Any reference herein to the Registration Statement, the Basic Prospectus, any

         offering and sale of the Securities. The Company may have filed one or
         more amendments thereto, including a Preliminary Final Prospectus, each
         of which has previously been furnished to you. The Company will next

         amendment to such registration statement (including the form of final
         prospectus supplement) or (3) a final prospectus in accordance with
         Rules 415 and 424(b). In the case of clause (1), the Company has

         Date, all information (other than Rule 430A Information) required by
         the Act and the rules thereunder to be included in such registration
         statement and the Final Prospectus. As filed, such final prospectus
         supplement or such amendment and form of final prospectus supplement
         shall contain all Rule 430A Information, together with all other such
         required information, and, except to the extent the Representatives
         shall agree in writing to a modification, shall be in all substantive
         respects in the form furnished to you prior to the Execution Time or,
         to the extent not completed at the Execution Time, shall contain only
         such specific additional information and other changes (beyond that
         contained in the Basic Prospectus and any Preliminary Final Prospectus)
         as the Company has advised you, prior to the Execution Time, will be
         included or made therein. The Registration Statement, at the Execution
         Time, meets the requirements set forth in Rule 415(a)(1)(x).

                  (b) On the Effective Date, the Registration Statement did or

         in all material respects with the applicable requirements of the Act,
         the Exchange Act and the Trust Indenture Act and the respective rules
         thereunder; on the Effective Date and at the Execution Time, the
         Registration Statement did not or will not contain any untrue statement
         of a material fact or omit to state any material fact required to be
         stated therein or necessary in order to make the statements therein not
         misleading; on the Effective Date and on the Closing Date the Indenture
         did or will comply in all material respects with the applicable
         requirements of the Trust Indenture Act and the rules thereunder; and,
         on the Effective Date, the Final Prospectus, if not filed pursuant to
         Rule 424(b), will not, and on the date of any filing pursuant to Rule
         424(b) and on the Closing Date, the Final Prospectus (together with any
         supplement thereto) will not, include 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; provided, however, that the
         Company makes no representations or warranties as to (i) that part of
         the Registration Statement which shall constitute the Statement of
         Eligibility and Qualification (Form T-1) under the Trust Indenture Act
         of the Trustee or (ii) the information contained in or omitted from the
         Registration Statement or the Final Prospectus (or any supplement

         the Representatives specifically for inclusion in the Registration
         Statement or the Final Prospectus (or any supplement thereto).

         Securities.

                  (j) The statements in the Final Prospectus under the heading

         the Indenture and delivered to and paid for by the Underwriters, will
         have been duly executed and delivered by the Company and will
         constitute the legal, valid and binding obligations of the Company
         entitled to the benefits of the Indenture (subject, as to the
         enforcement of remedies, to applicable bankruptcy, insolvency,
         moratorium or other laws affecting creditors' rights generally from
         time to time in effect and to general principles of equity).

                  (l) No consent, approval, authorization, filing with or order
         of any court or governmental agency or body is required in connection
         with the transactions contemplated herein or in the Indenture, except
         such as will be obtained under the Act and the Trust Indenture Act and

                  (m) Neither the execution and delivery of the Indenture or
         this Agreement, the issue and sale of the Securities, nor the
         consummation of any other of the transactions herein or therein
         contemplated, nor the fulfillment of the terms hereof or thereof will
         conflict with, result in a breach or violation or imposition of any
         lien, charge or encumbrance upon any property or assets of the Company
         or any of its subsidiaries pursuant to, (i) the charter or by-laws of
         the Company or any of its subsidiaries; (ii) the terms of any
         indenture, contract, lease, mortgage, deed of trust, note agreement,
         loan agreement or other agreement, obligation, condition, covenant or
         instrument to which the Company or any of its subsidiaries is a party
         or bound or to which its or their property is subject; or (iii) any
         statute, law, rule, regulation, judgment, order or decree applicable to
         the Company or any of its subsidiaries of any court, regulatory body,
         administrative agency, governmental body, arbitrator or other authority
         having jurisdiction over the Company or any of its subsidiaries or any
         of its or their properties.

                  (n) The consolidated historical financial statements and
         schedules of the Company and its consolidated subsidiaries included in

         Final Prospectus fairly present, on the basis stated in the Final
         Prospectus, the information included therein; the pro forma combined
         financial data included in the Final Prospectus includes assumptions
         that provide a reasonable basis for presenting the significant effects
         directly attributable to the transactions and events described therein,
         the related pro forma adjustments give appropriate effect to those
         assumptions, and the pro forma adjustments reflect the proper
         application of those adjustments to the historical financial statement
         amounts in the pro forma combined financial data included in the Final
         Prospectus; the

         pro forma combined financial data included in the Final Prospectus
         complies as to form in all material respects with the applicable
         accounting requirements of Regulation S-X under the Act; and the pro
         forma adjustments have been properly applied to the historical amounts
         in the compilation of such data.

                  (o) No action, suit or proceeding by or before any court or
         governmental agency, authority or body or any arbitrator involving the
         Company or any of its subsidiaries or its or their property is pending
         or, to the best knowledge of the Company, threatened that (i) could
         reasonably be expected to have a material adverse effect on the
         performance of this Agreement or the Indenture, or the consummation of
         any of the transactions contemplated hereby or thereby; or (ii) could
         reasonably be expected to have a material adverse effect on the
         condition (financial or otherwise), prospects, earnings, business or
         properties of the Company and its subsidiaries, taken as a whole,
         whether or not arising from transactions in the ordinary course of
         business, except as set forth in or contemplated in the Final
         Prospectus (exclusive of any amendment or supplement thereto).

                  (p) Each of the Company and each of its subsidiaries owns or
         leases all such properties as are necessary to the conduct of its
         operations as presently conducted.

                  (q) Neither the Company nor any subsidiary is in violation or
         default of (i) any provision of its charter or bylaws; (ii) the terms
         of any indenture, contract, lease, mortgage, deed of trust, note
         agreement, loan agreement or other agreement, obligation, condition,
         covenant or instrument to which it is a party or bound or to which its
         property is subject; or (iii) any statute, law, rule, regulation,
         judgment, order or decree applicable to the Company or any of its
         subsidiaries of any court, regulatory body, administrative agency,
         governmental body, arbitrator or other authority having jurisdiction
         over the Company or such subsidiary or any of its properties, as
         applicable, which violation or default in the case of clauses (ii) and
         (iii), individually or in the aggregate could, if continued, have a
         material adverse effect on the condition (financial or otherwise),
         prospects, earnings, business or properties of the Company and its
         subsidiaries taken as a whole.

                  (r) PricewaterhouseCoopers LLP and Arthur Andersen LLP, who
         have certified certain financial statements of the Company and Snyder

         local tax returns that are required to be filed or has requested
         extensions thereof (except in any case in which the failure so to file
         would not have a material adverse effect on the condition (financial or



                                       5

         otherwise), prospects, earnings, business or properties of the Company
         and its subsidiaries, taken as a whole, whether or not arising from
         transactions in the ordinary course of business, except as set forth in

         supplement thereto) and has paid all taxes required to be paid by it
         and any other assessment, fine or penalty levied against it, to the
         extent that any of the foregoing is due and payable, except for any
         such assessment, fine or penalty that is currently being contested in
         good faith or as would not have a material adverse effect on the
         condition (financial or otherwise), prospects, earnings, business or
         properties of the Company and its subsidiaries, taken as a whole,
         whether or not arising from transactions in the ordinary course of

         the Company or from transferring any of such subsidiary's property or
         assets to the Company or any other subsidiary of the Company, except as
         described in or contemplated by the Final Prospectus or as arise under
         applicable law.

                  (w) The Company and its subsidiaries possess all licenses,
         certificates, permits and other authorizations issued by the
         appropriate federal, state or foreign regulatory authorities necessary
         to conduct their respective businesses, and neither the Company nor any
         such subsidiary has received any notice of proceedings relating to the
         revocation or modification of any such certificate, authorization or
         permit which, singly or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would have a material adverse
         effect on the condition (financial or otherwise), prospects, earnings,
         business or properties of the Company and its subsidiaries, taken as a
         whole, whether or not arising from transactions in the ordinary course

         investigation or remediation of any disposal or release of hazardous or
         toxic substances or wastes, pollutants or contaminants, except where
         such non-compliance with Environmental Laws, failure to receive
         required permits, licenses or other approvals, or liability would not,
         individually or in the aggregate, have a material adverse change in the
         condition (financial or otherwise), prospects, earnings, business or
         properties of the Company and its subsidiaries, taken as a whole,
         whether or not arising from transactions

Underwriters that:

                  (a) The Company will use its best efforts to cause the
         Registration Statement, if not effective at the Execution Time, and any
         amendment thereof, to become effective. Prior to the termination of the
         offering of the Securities, the Company will not file any amendment of
         the Registration Statement or supplement (including the Final
         Prospectus or any Preliminary Final Prospectus) to the Basic Prospectus
         or any Rule 462(b) Registration Statement unless the Company has
         furnished you a copy for your review prior to filing and will not file
         any such proposed amendment or supplement to which you reasonably
         object. Subject to the foregoing sentence, if the Registration
         Statement has become or becomes effective pursuant to Rule 430A, or
         filing of the Final Prospectus is otherwise required under Rule 424(b),
         the Company will cause the Final Prospectus, properly completed, and
         any supplement thereto to be filed with the Commission pursuant to the
         applicable paragraph of Rule 424(b) within the time period prescribed
         and



                                       7

         will provide evidence satisfactory to the Representatives of such
         timely filing. The Company will promptly advise the Representatives (1)
         when the Registration Statement, if not effective at the Execution
         Time, shall have become effective, (2) when the Final Prospectus, and
         any supplement thereto, shall have been filed (if required) with the
         Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration
         Statement shall have been filed with the Commission, (3) when, prior to
         termination of the offering of the Securities, any amendment to the
         Registration Statement shall have been filed or become effective, (4)
         of any request by the Commission or its staff for any amendment of the
         Registration Statement, or any Rule 462(b) Registration Statement, or
         for any supplement to the Final Prospectus or for any additional
         information, (5) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or the
         institution or threatening of any proceeding for that purpose and (6)
         of the receipt by the Company of any notification with respect to the
         suspension of the qualification of the Securities for sale in any
         jurisdiction or the institution or threatening of any proceeding for
         such purpose. The Company will use its best efforts to prevent the
         issuance of any such stop order or the suspension of any such
         qualification and, if issued, to obtain as soon as possible the
         withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Final Prospectus as then supplemented would
         include any untrue statement of a material fact or omit to state any
         material fact necessary to make the statements therein in the light of
         the circumstances under which they were made not misleading, or if it
         shall be necessary to amend the Registration Statement or supplement
         the Final Prospectus to comply with the Act or the Exchange Act or the
         respective rules thereunder, the Company promptly will (1) notify the
         Representatives of such event, (2) prepare and file with the
         Commission, subject to the second sentence of paragraph (a) of this
         Section 5, an amendment or supplement which will correct such statement
         or omission or effect such compliance and (3) supply any supplemented
         Final Prospectus to you in such quantities as you may reasonably
         request.

                  (c) As soon as practicable, the Company will make generally
         available to its security holders and to the Representatives an
         earnings statement or statements of the Company and its subsidiaries
         which will satisfy the provisions of Section 11(a) of the Act and Rule
         158 under the Act.

                  (d) The Company will furnish to the Representatives and
         counsel for the Underwriters, without charge, signed copies of the
         Registration Statement (including exhibits thereto) and to each other
         Underwriter a copy of the Registration Statement (without exhibits
         thereto) and, so long as delivery of a prospectus by an Underwriter or
         dealer may be required by the Act, as many copies of each Preliminary
         Final Prospectus and the Final Prospectus and any supplement thereto as
         the Representatives may reasonably request. The Company will pay the
         expenses of printing or other production of all documents relating to
         the offering.

                  (e) The Company will arrange, if necessary, for the
         qualification of the Securities for sale under the laws of such
         jurisdictions as the Representatives may designate, will



                                       8
   9

         maintain such qualifications in effect so long as required for the
         distribution of the Securities and will pay any fee of the National
         Association of Securities Dealers, Inc., in connection with its review
         of the offering; provided that in no event shall the Company be
         obligated to qualify to do business in any jurisdiction where it is not
         now so qualified or to take any action that would subject it to service
         of process in suits, other than those arising out of the offering or
         sale of the Securities, in any jurisdiction where it is not now so
         subject.

                  (f) The Company will not, without the prior written consent of
         Salomon Smith Barney Inc., offer, sell, contract to sell, pledge, or
         otherwise dispose of, (or enter into any transaction which is designed
         to, or might reasonably be expected to, result in the disposition
         (whether by actual disposition or effective economic disposition due to
         cash settlement or otherwise) by the Company or any affiliate of the
         Company or any person in privity with the Company or any affiliate of
         the Company) directly or indirectly, including the filing (or
         participation in the filing) of a registration statement with the
         Commission in respect of, or establish or increase a put equivalent
         position or liquidate or decrease a call equivalent position within the
         meaning of Section 16 of the Exchange Act, any debt securities issued
         or guaranteed by the Company (other than the Securities) or publicly
         announce an intention to effect any such transaction, until the
         Business Day set forth on Schedule I hereto. For purposes of the
         foregoing, "affiliate" shall have the meaning assigned to such term
         under the Exchange Act.

                  (g) The Company will not take, directly or indirectly, any
         action designed to or which has constituted or which might reasonably
         be expected to cause or result, under the Exchange Act or otherwise, in
         stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the Securities.

                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Securities shall be subject to
the accuracy of the representations and warranties on the part of the Company
contained herein as of the Execution Time and the Closing Date, to the accuracy
of the statements of the Company made in any certificates pursuant to the
provisions hereof, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

                  (a) If the Registration Statement has not become effective
         prior to the Execution Time, unless the Representatives agree in
         writing to a later time, the Registration Statement will become
         effective not later than (i) 6:00 PM New York City time, on the date of
         determination of the public offering price, if such determination
         occurred at or prior to 3:00 PM New York City time on such date or (ii)
         9:30 AM on the Business Day following the day on which the public
         offering price was determined, if such determination occurred after
         3:00 PM New York City time on such date; if filing of the Final
         Prospectus, or any supplement thereto, is required pursuant to Rule
         424(b), the Final Prospectus, and any such supplement, will be filed in
         the manner and within the time period required by Rule 424(b); and no
         stop order suspending the effectiveness of the Registration Statement
         shall have been issued and no proceedings for that purpose shall have
         been instituted or threatened.

                  chartered or organized, with full corporate power and
                  authority to own or lease, as the case may be, and to operate

                  free and clear of any perfected security interest and, to the
                  knowledge of such counsel, after due inquiry, any other

                  or other laws affecting creditors' rights generally from time
                  to time in effect and to general principles of equity,

                  the Securities have been duly authorized and, when executed
                  and authenticated in accordance with the provisions of the
                  Indenture and delivered to and paid for by the Underwriters
                  pursuant to this Agreement, will constitute legal, valid and
                  binding obligations of the Company entitled to the benefits of
                  the Indenture;

                           (v) to the knowledge of such counsel, there is no
                  pending or threatened



                                       10

                  governmental agency, authority or body or any arbitrator
                  involving the Company or any of its subsidiaries or its or
                  their property, of a character required to be disclosed in the
                  Registration Statement which is not adequately disclosed in
                  the Final Prospectus, and there is no franchise, contract or
                  other document of a character required to be described in the
                  Registration Statement or Final Prospectus, or to be filed as
                  an exhibit thereto, which is not described or filed as
                  required; and the statements included or incorporated by
                  reference in the Final Prospectus under the captions "Certain
                  United States Federal Tax Consequences for Non-United States
                  Holders" and "Description of Notes" fairly summarize the
                  matters therein described.

                           (vi) the Registration Statement has become effective
                  under the Act; any required filing of the Basic Prospectus,
                  any Preliminary Final Prospectus and the Final Prospectus, and
                  any supplements thereto, pursuant to Rule 424(b) has been made
                  in the manner and within the time period required by Rule
                  424(b); to the knowledge of such counsel, no stop order
                  suspending the effectiveness of the Registration Statement has
                  been issued, no proceedings for that purpose have been
                  instituted or threatened, and the Registration Statement and
                  the Final Prospectus (other than the financial statements and
                  other financial information contained therein, as to which
                  such counsel need express no opinion) comply as to form in all
                  material respects with the applicable requirements of the Act,
                  the Exchange Act and the Trust Indenture Act and the
                  respective rules thereunder; and on the Effective Date or at
                  the Execution Time of the Registration Statement (A) each
                  document, if any, filed pursuant to the Exchange Act and
                  incorporated by reference in the Final Prospectus appeared on
                  its face to be appropriately responsive in all material
                  respects to the requirements of the Exchange Act and (B) the
                  Registration Statement and Final Prospectus appeared on their
                  face to be appropriately responsive in all material respects
                  to the requirements of the Exchange Act (in each case other
                  than financial statements and schedules and other financial or
                  statistical data and estimates of reserves or other
                  information included or incorporated by reference therein or
                  omitted therefrom as to which such counsel need not express
                  any opinion);

                           (vii) this Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (viii) the Company is not and, after giving effect to
                  the offering and sale of the Securities and the application of
                  the proceeds thereof as described in the Final Prospectus,
                  will not be an "investment company" as defined in the
                  Investment Company Act of 1940, as amended;

   12

                           (ix) no consent, approval, authorization, filing with
                  or order of any court or governmental agency or body is
                  required in connection with the transactions contemplated
                  herein, except such as have been obtained under the Act and
                  such as may be required under the blue sky laws of any
                  jurisdiction in connection with the purchase and distribution
                  of the Securities by the Underwriters in the manner
                  contemplated in this Agreement and in the Final Prospectus and
                  such other approvals (specified in such opinion) as have been
                  obtained;

                           (x) neither the execution and delivery of the
                  Indenture, the issue and sale of the Securities, nor the
                  consummation of any other of the transactions herein
                  contemplated nor the fulfillment of the terms hereof will
                  conflict with, result in a breach or violation of or
                  imposition of any lien, charge or encumbrance upon any
                  property or assets of the Company or its subsidiaries pursuant
                  to, (i) the charter or by-laws of the Company or any of its
                  subsidiaries listed in Exhibit A hereto, (ii) the terms of
                  any indenture, or any material contract, lease, mortgage, deed
                  of trust, note agreement, loan agreement or other agreement,
                  obligation, condition, covenant or instrument to which the
                  Company or its subsidiaries is a party or bound or to which
                  its or their property is subject, or (iii) any statute, law,
                  rule, regulation, judgment, order or decree applicable to the
                  Company or its subsidiaries of any court, regulatory body,
                  administrative agency, governmental body, arbitrator or other
                  authority having jurisdiction over the Company or its
                  subsidiaries or any of its or their properties; and

                           (xi) no holders of securities of the Company have
                  rights to the registration of such securities under the
                  Registration Statement.

                  In addition, such counsel's opinion shall state that in the
         course of the preparation by the Company of the Registration Statement
         and the Preliminary Final Prospectus and the Final Prospectus
         (including the documents incorporated by reference therein), such
         counsel has participated in conferences with certain of the officers
         and representatives of the Company, the Company's independent
         accountants, the Underwriters and counsel for the Underwriters at which
         the Registration Statement, the Preliminary Final Prospectus and Final
         Prospectus were discussed. Such counsel' opinion shall further state
         that between the date of effectiveness of the Registration Statement
         and the date hereof, such counsel participated in additional
         conferences with certain officers and representatives of the Company,
         the Company's independent accountants, the Underwriters and counsel for
         the Underwriters at which portions of the Registration Statement, the
         Preliminary Final Prospectus and the Final Prospectus were discussed.
         Further, 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, the Preliminary
         Final Prospectus or the Final Prospectus and has not made any
         independent check or verification thereof, except as specifically
         described in the opinion in paragraphs (v) and (vi) above. Subject to
         the foregoing, no facts have come to such counsel's attention that have
         caused such counsel to believe that the Registration Statement, at the
         time it became effective, contained any untrue statement of a material
         fact or omitted to state a material fact required to be stated therein
         or necessary in order to make the statements therein not



                                       12
   13

         misleading, or that the Final Prospectus, as of its date, contained any
         untrue statement of a material fact or omitted to state a material fact
         necessary in order to make the statements therein, in light of the
         circumstances under which they were made, not misleading. Also, subject
         to the foregoing, no facts have come to such counsel's attention in the
         course of the proceedings described in the first and second sentences
         of this paragraph that caused such counsel to believe that the Final
         Prospectus as of the date hereof contains any untrue statement of a
         material fact or omits to state a material fact necessary in order to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading. Such counsel will not express any
         belief, however, with respect to financial statements, schedules or
         notes thereto or other financial or statistical data or reserve reports
         included or incorporated by reference in or omitted from the
         Registration Statement or Final Prospectus, or the Form T-1 of the
         Trustee.



                  In rendering such opinion, such counsel may rely (A) as to
         matters involving the application of laws of any jurisdiction other
         than the State of Delaware or the Federal laws of the United States, to
         the extent they deem proper and specified in such opinion, upon the
         opinion of other counsel of good standing whom they believe to be
         reliable and who are satisfactory to counsel for the Underwriters and
         (B) as to matters of fact, to the extent they deem proper, on
         certificates of responsible officers of the Company and public
         officials. References to the Final Prospectus in this paragraph (b)
         include any supplements thereto at the Closing Date.

                  (c) The Representatives shall have received from Vinson &
         Elkins L.L.P., counsel for the Underwriters, such opinion or opinions,
         dated the Closing Date and addressed to the Representatives, with
         respect to the issuance and sale of the Securities, the Indenture, the
         Registration Statement, the Final Prospectus (together with any
         supplement thereto) and other related matters as the Representatives
         may reasonably require, and the Company shall have furnished to such
         counsel such documents as they request for the purpose of enabling them
         to pass upon such matters.

                  (d) The Company shall have furnished to the Representatives a
         certificate of the Company, signed by the Chairman of the Board or the
         Chief Executive Officer and the principal financial or accounting
         officer of the Company, dated the Closing Date, to the effect that the
         signers of such certificate have carefully examined the Registration
         Statement, the Final Prospectus, any supplements to the Final
         Prospectus and this Agreement and that:

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

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement has been issued and no proceedings
                  for that purpose have been



                                       13
   14

                  instituted or, to the Company's knowledge, threatened; and

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

                  (e) At the Execution Time and the Closing Date, each firm of
         accountants who have certified the financial statements of the Company
         and its Subsidiaries and other relevant entities, including, without
         limitation, Snyder Oil Corporation and Santa Fe Energy Resources, Inc.,
         included or incorporated by reference in the Registration Statement or
         Final Prospectus, shall have furnished to the Representatives a letter
         or letters, to the effect set forth in Annex I hereto, and including
         such other matters as the Representatives may reasonably request, in
         form and substance satisfactory to the Representatives.

                  (f) Subsequent to the Execution Time or, if earlier, the dates
         as of which information is given in the Registration Statement
         (exclusive of any amendment thereof) and the Final Prospectus
         (exclusive of any supplement thereto), there shall not have been (i)
         any change or decrease specified in the letter or letters referred to
         in paragraph (e) of this Section 6 or (ii) any change, or any
         development involving a prospective change, in or affecting the
         condition (financial or otherwise), earnings, business or properties of
         the Company and its subsidiaries, taken as a whole, whether or not
         arising from transactions in the ordinary course of business, except as
         set forth in or contemplated in the Final Prospectus (exclusive of any
         supplement thereto) the effect of which, in any case referred to in
         clause (i) or (ii) above, is, in the sole judgment of the
         Representatives, so material and adverse as to make it impractical or
         inadvisable to proceed with the offering or delivery of the Securities
         as contemplated by the Registration Statement (exclusive of any
         amendment thereof) and the Final Prospectus (exclusive of any
         supplement thereto).

                  (g) Subsequent to the Execution Time, there shall not have
         been any decrease in the rating of any of the Company's debt securities
         by any "nationally recognized statistical rating organization" (as
         defined for purposes of Rule 436(g) under the Act) or any notice given
         of any intended or potential decrease in any such rating or of a
         possible change in any such rating that does not indicate the direction
         of the possible change.

                  (h) Prior to the Closing Date, the Company shall have
         furnished to the Representatives such documents as the Representatives
         may reasonably request for the purpose of enabling them to pass upon
         the issuance and sale of the Securities as herein contemplated, or in
         order to evidence the accuracy of any of the representations or
         warranties, or the fulfillment of any of the conditions, herein
         contemplated.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and



                                       14
   15

certificates mentioned above or elsewhere in this Agreement shall not be in all
material respects reasonably satisfactory in form and substance to the
Representatives and counsel for the Underwriters, this Agreement and all
obligations of the Underwriters hereunder may be canceled at, or at any time
prior to, the Closing Date by the Representatives. Notice of such cancelation
shall be given to the Company in writing or by telephone or facsimile confirmed
in writing.

                  The documents required to be delivered by this Section 6 shall
be delivered on the Closing Date at a place and time agreed upon by the Company
and the Underwriters.

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

                  8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in the Basic
Prospectus, any Preliminary Final Prospectus or the Final Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any Underwriter through the Representatives
specifically for inclusion therein, provided further, however, that the
foregoing indemnity agreement with respect to any Preliminary Final Prospectus
shall not inure to the benefit of any Underwriter who failed to deliver a Final
Prospectus (as then amended or supplemented, provided by the Company to the
Underwriters in the requisite quantity and on a timely basis to permit proper
delivery on or prior to the Closing Date) to the person asserting any losses,
claims, damages and liabilities and judgments caused by any untrue statement or
alleged untrue statement of a material fact contained in any Preliminary Final
Prospectus or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or



                                       15
   16

necessary to make the statements therein not misleading, if such material
misstatement or omission or alleged material misstatement or omission was cured
in such Final Prospectus and such Final Prospectus was required by law to be
delivered at or prior to the written confirmation of sale to such person. This
indemnity agreement will be in addition to any liability which the Company may
otherwise have.

                  (b) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement, and each person who controls the
Company within the meaning of either the Act or the Exchange Act, to the same
extent as the foregoing indemnity from the Company to each Underwriter, but only
with reference to written information relating to such Underwriter furnished to
the Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have. The Company acknowledges that the statements
set forth in the last paragraph of the cover page, the paragraphs addressing
stabilization, syndicate transactions penalty bids and the performance of
financial advisory services by the underwriters under the caption
"Underwriting", the sentences related to concessions and reallowances, and the
list of Underwriters and their respective participation in the sale of the
Securities in any Final Prospectus or Preliminary Final Prospectus constitute
the only information furnished in writing by or on behalf of the several
Underwriters for inclusion in any Preliminary Final Prospectus or the Final
Prospectus.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the



                                       16
   17

institution of such action or (iv) the indemnifying party shall authorize the
indemnified party to employ separate counsel at the expense of the indemnifying
party. An indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters severally
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
and one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and by the Underwriters on the other from the offering of the Securities;
provided, however, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount
or commission applicable to the Securities purchased by such Underwriter
hereunder. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
of the Underwriters on the other in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses) received by
it, and benefits received by the Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the Final Prospectus. Relative fault shall be determined by
reference to, among other things, whether any untrue or any alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information provided by the Company on the one hand or
the Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Company and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such
Underwriter, and each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).



                                       17
   18

                  9. Default by an Underwriter. If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule II hereto bears to the
aggregate principal amount of Securities set forth opposite the names of all the
remaining Underwriters) the Securities which the defaulting Underwriter or
Underwriters agreed but failed to purchase; provided, however, that in the event
that the aggregate principal amount of Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of
the aggregate principal amount of Securities set forth in Schedule II hereto,
the remaining Underwriters shall have the right to purchase all, but shall not
be under any obligation to purchase any, of the Securities, and if such
nondefaulting Underwriters do not purchase all the Securities, this Agreement
will terminate without liability to any nondefaulting Underwriter or the
Company. In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Final Prospectus or in
any other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the Company and any nondefaulting Underwriter for damages occasioned by its
default hereunder.

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

                  11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the 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
the officers, directors, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

                  12. Notices. All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will be
mailed, delivered or telefaxed to the Salomon Smith Barney Inc. General Counsel
(fax no.: (212) 816-7912) and confirmed to the General Counsel, Salomon Smith
Barney Inc., at 388 Greenwich Street, New York, New York,

                  13. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers, directors, employees, agents and controlling persons referred to in
Section 8 hereof, and no other person will have any right or obligation
hereunder.

                  14. Applicable Law. This Agreement will be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

                  15. Counterparts. This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

         Appropriate Accountants (as defined herein) shall have furnished to the
         Representatives a letter or letters, dated respectively as of the
         Execution Time and as of the Closing Date, in form and substance
         satisfactory to the Representatives, confirming that they are
         independent accountants within the meaning of the Act and the Exchange
         Act and the respective applicable rules and regulations adopted by the
         Commission thereunder and that they have audited the year-end financial
         information included or incorporated in the Registration Statement and
         the Final Prospectus and performed a review of the unaudited interim
         financial information included or incorporated in the Registration
         Statement and the Final Prospectus in accordance with Statement on
         Auditing Standards No. 71, and stating in effect that:

                           (i) in their opinion the audited financial statements
                  and financial statement schedules and pro forma financial
                  statements included or incorporated by reference in the
                  Registration Statement and the Final Prospectus (including
                  those incorporated therein by reference) and reported on by
                  them comply as to form in all material respects with the
                  applicable accounting requirements of the Act and the Exchange
                  Act and the related rules and regulations adopted by the
                  Commission;

                           (ii) on the basis of a reading of the latest
                  unaudited financial statements made available by the Relevant
                  Entity (as defined herein); their limited review in accordance
                  with standards established under Statement on Auditing
                  Standards No. 71 of the unaudited interim financial
                  information as included in the Registration Statement and
                  Final Prospectus (including those incorporated therein by
                  reference), carrying out certain specified procedures (but not
                  an examination in accordance with generally accepted auditing
                  standards) which would not necessarily reveal matters of
                  significance with respect to the comments set forth in such
                  letter, a reading of the minutes of the meetings of the
                  stockholders, directors and any committees of the Relevant
                  Entity the Representatives may reasonably request; and
                  inquiries of certain officials of the Relevant Entity who have
                  responsibility for financial and accounting matters of the
                  Relevant Entity as to transactions and events subsequent to
                  the date of the most recent financial statements included in
                  the Final Prospectus, nothing came to their attention which
                  caused them to believe that:

                                    (1) any unaudited financial statements
                           included or incorporated by reference in the
                           Registration Statement and the Final Prospectus do
                           not comply as to form in all material respects with
                           applicable accounting requirements of the Act and
                           with the related rules and regulations adopted by the
                           Commission with respect to financial statements
                           included or incorporated by reference in quarterly
                           reports on Form 10-Q under the Exchange Act; and said
                           unaudited financial statements are not in conformity
                           with generally accepted accounting principles applied
                           on a



                                       22

                           basis substantially consistent with that of the
                           audited financial statements included or incorporated
                           by reference in the Registration Statement and the
                           Final Prospectus;

                                    (2) with respect to the period subsequent to
                           the date of the most recent financial statements
                           (other than capsule information), audited or
                           unaudited, included or incorporated by reference in
                           the Registration Statement and the Final Prospectus,
                           there were any changes, at a specified date not more
                           than five days prior to the date of the letter, in
                           the long-term debt or capital stock of the Relevant
                           Entity or decreases in the stockholders' equity of
                           the Relevant Entity or other balance sheet items the
                           Representatives may reasonably request as compared
                           with the amounts shown on the most recent financial
                           statements included or incorporated by reference in
                           the Registration Statement and the Final Prospectus
                           to such specified date, or there were any decreases,
                           as compared with the corresponding period in the
                           preceding year or the preceding quarter in net
                           revenues or income before income taxes or in total or
                           per share amounts of net income of the Relevant
                           Entity or any other income statement items as the
                           Representatives may reasonable request, except in all
                           instances for changes or decreases set forth in such
                           letter, in which case the letter shall be accompanied
                           by an explanation by the Company as to the
                           significance thereof unless said explanation is not
                           deemed necessary by the Representatives, or

                                     (3) the information included or
                           incorporated by reference in the Registration
                           Statement and Final Prospectus in response to
                           Regulation S-K, Item 301 (Selected Financial Data),
                           Item 302 (Supplementary Financial Information), Item
                           402 (Executive Compensation) and Item 503(d) (Ratio
                           of Earnings to Fixed Charges) is not in conformity
                           with the applicable disclosure requirements of
                           Regulation S-K; and

                           (iii) they have performed certain other specified
                  procedures as a result of which they determined that certain
                  information of an accounting, financial or statistical nature
                  (which is limited to accounting, financial or statistical
                  information derived from the general accounting records of the
                  Relevant Entity) set forth in the Registration Statement and
                  the Final Prospectus, including the information in Items 1, 2,
                  6, 7 and 11 of any Annual Report on Form 10-K, included or
                  incorporated by reference in the Registration Statement and
                  the Final Prospectus, and the information included in the
                  "Management's Discussion and Analysis of Financial Condition
                  and Results of Operations" included or incorporated by
                  reference in any Relevant Entity's Quarterly Reports on Form
                  10-Q, incorporated by reference in the Registration Statement
                  and the Final Prospectus, agrees with the accounting records
                  of the Relevant Entity, excluding any questions of legal
                  interpretation; and

                           (iv) on the basis of a reading of the unaudited pro
                  forma financial statements included or incorporated by
                  reference in the Registration Statement


                                       23

                  and the Final Prospectus (the "pro forma financial
                  statements"); carrying out certain specified procedures;
                  inquiries of certain officials of the Relevant Entity who have
                  responsibility for financial and accounting matters; and
                  proving the arithmetic accuracy of the application of the pro
                  forma adjustments to the historical amounts in the pro forma
                  financial statements, nothing came to their attention which
                  caused them to believe that the pro forma financial statements
                  do not comply as to form in all material respects with the
                  applicable accounting requirements of Rule 11-02 of Regulation
                  S-X or that the pro forma adjustments have not been properly
                  applied to the historical amounts in the compilation of such
                  statements.
