Dear Sirs:

         Eastern States Oil & Gas, Inc., a Delaware corporation (the "Company"),
proposes to sell to the Underwriters named in Schedule 1 hereto (the
"Underwriters") 7,875,000 units (the "Firm Units") of beneficial interest (the
"Trust Units") in the Appalachian Natural Gas Trust, a grantor trust formed
under the laws of the State of Delaware (the "Trust") to hold net profits
interests (the "Net Profits Interests") in certain natural gas producing
properties owned by the Company (the "Underlying Properties") in the Appalachian
Basin area of Kentucky and West Virginia. In addition, the Company proposes to
grant to the Underwriters an option to purchase up to an additional 1,181,250
Trust Units on the terms and for the purposes set forth in Section 2 (the
"Option Units"). The Firm Units and the Option Units, if purchased, are
hereinafter collectively called the "Units."

         1. Representations and Warranties of the Statoil Parties. The Company,
Statoil Energy, Inc., a Virginia corporation ("Statoil Energy"), and Statoil
Energy Holdings, Inc., a Delaware corporation ("Statoil Energy Holdings" and,
collectively with the Company and Statoil Energy, the


   2


"Statoil Parties"), jointly and severally represent and warrant to, and agree
with, each of the Underwriters that:

         (a) A joint registration statement on Form S-1 (File No. 333-85955)
with respect to the Units (i) has been prepared by the Company and the Trust in
conformity with the requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and the rules and regulations (the "Rules and Regulations")
of the Securities and Exchange Commission (the "Commission") thereunder, (ii)
has been filed with the Commission under the Securities Act and (iii) has become
effective under the Securities Act. Copies of such registration statement as
amended to date have been delivered by the Company to you as the representatives
(the "Representatives") of the Underwriters. As used in this Agreement,
"Effective Time" means the date and the time as of which such registration
statement, or the most recent post-effective amendment thereto, if any, was
declared effective by the Commission; "Effective Date" means the date of the
Effective Time; "Preliminary Prospectus" means each prospectus included in such
registration statement, or amendments thereof, before it became effective under
the Securities Act and any prospectus filed with the Commission by the Company
and the Trust with the consent of the Representatives pursuant to Rule 424(a) of
the Rules and Regulations; "Registration Statement" means such registration
statement, as amended at the Effective Time, including, if the Effective Date is
on or before the date of this Agreement, all information contained in the final
prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and
Regulations ("Rule 424(b)") in accordance with Section 5(a) hereof and deemed to
be a part of the registration statement as of the Effective Time pursuant to
paragraph (b) of Rule 430A of the Rules and Regulations; and "Prospectus" means
such final prospectus, as first filed with the Commission pursuant to paragraph
(1) or (4) of Rule 424(b) of the Rules and Regulations. If it is contemplated,
at the time this Agreement is executed, that a registration statement or
post-effective amendment will be filed pursuant to Rule 462(b) or Rule 462(d)
under the Securities Act before the offering of the Units may commence, the term
"Registration Statement" as used in this Agreement includes such registration
statement. The Commission has not issued any order preventing or suspending the
use of any Preliminary Prospectus.

         (b) Any Preliminary Prospectus, at the date of filing thereof with the
Commission, conformed in all material respects with the requirements of the
Securities Act and the Rules and Regulations and did not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. The
Registration Statement conforms, and the Prospectus and any further amendments
or supplements to the Registration Statement or the Prospectus will, when they
become effective or are filed with the Commission, conform in all material
respects to the requirements of the Securities Act and the Rules and Regulations
and do not and will not, as of the applicable effective date (as to the
Registration Statement and any amendment thereto) and as of the applicable
filing date (as to the Prospectus and any amendment or supplement thereto)
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading. Each of the statements made by the Company and the Trust in such
documents within the coverage of Rule 175(b) of the Rules and Regulations,
including (but not limited to) any statements with respect to future cash
distributions of the Trust, was made or will be made with a reasonable basis and
in good faith.

securities in the securities registered pursuant to the Registration Statement
or in any securities being registered pursuant to any other registration

instrument to which any of the Statoil Parties or any of their subsidiaries or

over any of the Statoil Parties or any of their subsidiaries or the Trust or any

         (t) All consents, approvals, authorizations and orders necessary for
the transfer of the Net Profits Interests to the Trust as described in the
Prospectus have been obtained and such transfer has not had the effect of
creating any lien, encumbrance, security interest, equity, charge or claim of
any kind in favor of any person with respect to any of the Net Profits Interests
(including any preferential right of purchase, or, with respect to any
properties in which the Company has acted as operator, any right to remove the
Company as operator) except to the extent such rights have been validly waived
in writing.

         (u) None of the Statoil Parties nor any of their subsidiaries is in (i)
violation of its certificate or articles of incorporation or bylaws or other
organizational documents, or of any law, statute, ordinance, administrative or
governmental rule or regulation applicable to it or of any order, judgment,
decree or injunction of any court or governmental agency or body having
jurisdiction over it, or (ii) breach, default (or an event which, with notice or
lapse of time or both, would constitute such an event) or violation in the
performance of any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or in any agreement,
indenture, lease or other instrument to which it is a party or by which it or
any of its properties may be bound. To the knowledge of the Statoil Parties, no
third party to any indenture, mortgage, deed of trust, loan agreement or other
agreement or instrument to which any of the Statoil Parties is a party or by
which any of them is bound or to which any of their properties are subject, is
in default under any such agreement.

         (v) Neither the Company nor any of its subsidiaries nor the Underlying
Properties has sustained since the date of the latest audited financial
statements included in the Prospectus any material loss or interference with its
business from fire, explosion, flood or other calamity, whether or not covered
by insurance, or from any labor dispute or court or governmental action, order
or decree, otherwise than as set forth or contemplated in the Prospectus; and,
since the respective dates as of which information is given in the Registration
Statement and the Prospectus, (i) neither the Company nor any of its
subsidiaries or the Trust has incurred any liability or obligation, indirect,
direct or contingent, or entered into any transactions, not in the ordinary
course of business, that, singly or in the aggregate, is material to the Company
and its subsidiaries, taken as a whole, or the Trust, (ii) there has not been
any change in the long-term debt of the Company or any of its subsidiaries or
any change in the number of outstanding Trust Units or (iii) there has not been
any

                                       -6-

   7


material adverse change, or any development involving a prospective material
adverse change, in or affecting the general affairs, management, financial
position, stockholders' equity or results of operations of the Company and its
subsidiaries, taken as a whole, the Trust or the Underlying Properties,
otherwise than as set forth or contemplated in the Prospectus.

         (w) The financial statements (including the related notes and
supporting schedules) included in the Registration Statement and the Prospectus
(and any amendment or supplement thereto) present fairly in all material
respects the financial position, results of operations and cash flows of the
entities or properties purported to be shown thereby, at the dates and for the
periods indicated, and have been prepared in conformity with generally accepted
accounting principles applied on a consistent basis throughout the periods
indicated, except to the extent disclosed therein. The pro forma statement of
distributable cash of the Trust included in the Registration Statement and the
Prospectus (and any amendment or supplement thereto) has been prepared in all
material respects in accordance with the applicable accounting requirements of
Article 11 of Regulation S-X of the Commission; the assumptions used in the
preparation of such pro forma financial statement are, in the opinion of the
management of the Statoil Parties, reasonable; and the pro forma adjustments
reflected in such pro forma financial statement have been properly applied to
the historical amounts in compilation of such pro forma financial statement.

         (x) Ernst & Young LLP, who have certified certain financial statements
of the Trust, the Company and the Underlying Properties included in the
Prospectus, are independent public accountants as required by the Securities Act
and the Rules and Regulations.

         (y) The information supplied by the Company to its independent
petroleum engineering consultants, Ryder Scott Company, L.P., for purposes of
preparing the reserve reports used to calculate estimates of reserves of the
Company, the Underlying Properties and the Net Profits Interest included in the
Prospectus, including, without limitation, information relating to production,
costs of operation and development, current prices for production, agreements
relating to current and future operations and sales of production, was true and
correct in all material respects on the date supplied and was prepared in
accordance with customary industry practices. Ryder Scott Company, L.P. is
independent with respect to the Statoil Parties and the Trust.

         (z) The Company has good and marketable title to the Underlying
Properties, free and clear of all liens, claims, security interests or other
encumbrances, except (i) royalties, overriding royalties and other burdens under
oil and gas leases that do not reduce the Company's net revenue interests in the
Underlying Properties below those stated in Ryder Scott Company, L.P.'s reserve
report for the Underlying Properties included in the Prospectus, (ii) easements,
restrictions, rights-of-way and other matters that commonly affect property,
(iii) liens securing taxes and other governmental charges, or claims of
materialmen, mechanics and similar persons, not yet due and payable, (iv) liens
and encumbrances under operating agreements and unitization, pooling and
communitization agreements, declarations and orders, securing payment of amounts
not yet due and payable and of a scope and nature customary in the oil and gas
industry and (v) liens, encumbrances and defects that do not in the aggregate
materially affect the value of the Underlying Properties or materially interfere
with the use made or proposed to be made of such Underlying Properties by the

                                       -7-

   8



Company. All contracts, agreements or underlying leases that comprise a portion
of the Underlying Properties are in full force and effect, and the Company has
paid all royalties, rents and other charges to the extent due and payable
thereunder, is not in default under any of such underlying contracts, agreements
or leases, has received no notice of default from any other party thereto and
knows of no material default by any other party thereto.

         (aa) The working interests in oil, gas and mineral leases or mineral
interests which constitute a portion of the Underlying Properties held by the
Company reflect in all material respects the right of the Company to explore or
receive production from such Underlying Properties, and the care taken by the
Company and its subsidiaries with respect to acquiring or otherwise procuring
such leases or mineral interests was generally consistent with standard industry
practices for acquiring or procuring leases and interests therein to explore for
hydrocarbons.

         (bb) At each Delivery Date, the Trust will have good and marketable
title to the Net Profits Interests, free and clear of all liens, encumbrances,
security interests, equities, charges or claims, except liens securing taxes and
other governmental charges and liens, encumbrances and defects that do not in
the aggregate materially affect the value of the Net Profits Interests. The
descriptions of the Net Profits Interests in the Conveyances, including the
exhibits thereto, are complete and accurate in all material respects.

         (cc) The Company and its subsidiaries maintain insurance covering their
properties, operations, personnel and businesses against such losses and risks
as are reasonably adequate to protect them and their businesses in a manner
consistent with other businesses similarly situated. None of the Company nor its
subsidiaries has received notice from any insurer or agent of such insurer that
substantial capital improvements or other expenditures will have to be made in
order to continue such insurance; and all such insurance is outstanding and duly
in force on the date hereof and will be outstanding and duly in force on each
Delivery Date.

         (dd) Other than as set forth in the Prospectus, there are no legal or
governmental proceedings pending to which the Company or any of its subsidiaries
or the Trust is a party or of which any Underlying Property or the Net Profits
Interests is the subject which are required to be described in the Prospectus;
and, to the best of the Company's knowledge, no such proceedings are threatened
or contemplated by governmental authorities or threatened by others; and there
are no agreements, contracts, indentures, leases or other instruments that are
required to be described in the Registration Statement or the Prospectus or to
be filed as an exhibit to the Registration Statement that are not described or
filed as required by the Securities Act.

         (ee) Except as described in the Prospectus, no labor dispute by the
employees of the Company or any of its subsidiaries exists or, to the knowledge
of the Company, is imminent which might reasonably be expected to have a
material adverse effect on the condition (financial or other), business,
prospects, properties, net worth or results of operations of the Company or the
Trust.

         (ff) Each of the Company and its subsidiaries has filed (or has
obtained extensions with respect to) all material tax returns required to be
filed through the date hereof, which returns are

                                       -8-

   9


complete and correct in all material respects, and has timely paid all taxes
shown to be due pursuant to such returns, other than those (i) which, if not
paid, would not have a material adverse effect on the condition (financial or
other), business, prospects, properties, net worth or results of operations of
the Company and its subsidiaries, taken as a whole, or (ii) which are being
contested in good faith.

         (gg) The Company and its subsidiaries have, or at each Delivery Date
will have, such permits, consents, licenses, franchises and authorizations of
governmental or regulatory authorities ("permits") as are necessary to own or
lease their properties and to conduct their business in the manner described in
the Prospectus, subject to such qualifications as may be set forth in the
Prospectus and except for such permits which, if not obtained, would not have,
individually or in the aggregate, a material adverse effect upon the ability of
the Company and its subsidiaries, considered as a whole, to conduct their
businesses in all material respects as currently conducted and as contemplated
by the Prospectus to be conducted; the Company and its subsidiaries have, or at
each Delivery Date will have, fulfilled and performed all their material
obligations with respect to such permits and no event has occurred which allows,
or after notice or lapse of time would allow, revocation or termination thereof
or results in any impairment of the rights of the holder of any such permit,
except for such revocations, terminations and impairments that would not have a
material adverse effect upon the ability of the Company and its subsidiaries
considered as a whole to conduct their businesses in all material respects as
currently conducted and as contemplated by the Prospectus to be conducted,
subject in each case to such qualification as may be set forth in the
Prospectus.

         (hh) The Company (i) makes and keeps books, records and accounts,
which, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of assets and (ii) maintains systems of internal accounting
controls sufficient to provide reasonable assurances that (A) transactions are
executed in accordance with management's general or specific authorization; (B)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets; (C) access to assets is permitted only in
accordance with management's general or specific authorization; and (D) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

         (ii) To the knowledge of the Company, neither the Company nor any of
its subsidiaries, nor any director, officer, agent, employee or other person
associated with or acting on behalf of the Company or any of its subsidiaries,
has used any corporate funds for any unlawful contribution, gift, entertainment
or other unlawful expense relating to political activity; made any direct or
indirect unlawful payment to any foreign or domestic government official or
employee from corporate funds; violated or is in violation of any provision of
the Foreign Corrupt Practices Act of 1977; or made any bribe, rebate, payoff,
influence payment, kickback or other unlawful payment.

         (jj) The Company has reviewed its operations and that of its
subsidiaries and is in the process of reviewing the relevant operations of third
parties with which the Company or any of its subsidiaries has a material
relationship to evaluate the extent to which the business or operations of the
Company or any of its subsidiaries will be affected by the Year 2000 Problem. As
a result of such review, the Company has no reason to believe, and does not
believe, that the Year 2000 Problem will


                                      -9-
   10


have a material adverse effect on the condition (financial or other), business,
prospects, properties, net worth or results of operations of the Company and its
subsidiaries or result in any material loss or interference with the Company's
business or operations. The "Year 2000 Problem" as used herein means any
significant risk that computer hardware or software used in the receipt,
transmission, processing, manipulation, storage, retrieval, retransmission or

         (mm) Neither the Company nor the Trust is or, after giving effect to
the offering and sale of Trust Units, will be (i) an "investment company" or a
company "controlled by" an "investment company" as such terms are defined in the
Investment Company Act of 1940, as amended (the "Investment Company Act") or
(ii) a "public utility company," "holding company" or a "subsidiary company" of
a "holding company" or an "affiliate" thereof, under the Public Utility Holding
Company Act of 1935, as amended.

         (nn) The Company has not distributed and, prior to the later to occur
of (i) the First Delivery Date and (ii) completion of the distribution of the
Units, will not distribute, any prospectus (as defined under the Securities Act)
in connection with the offering and sale of the Units other than the
Registration Statement, any Preliminary Prospectus, the Prospectus or other
materials, if any, permitted by the Securities Act, including Rule 134 of the
Rules and Regulations.

         (oo) The Units have been approved for listing on the New York Stock
Exchange ("NYSE"), subject only to official notice of issuance.

         2. Purchase of the Units by the Underwriters. On the basis of the
representations and warranties contained in, and subject to the terms and
conditions of, this Agreement, the Company agrees to sell 7,875,000 Firm Units
to the several Underwriters, and each of the Underwriters, severally and not
jointly, agrees to purchase the number of Firm Units set opposite that
Underwriter's name in Schedule 1 hereto. The respective purchase obligations of
the Underwriters with respect to the Firm Units shall be rounded among the
Underwriters to avoid fractional shares, as the Representatives may determine.

         In addition, the Company grants to the Underwriters an option to
purchase up to 1,181,250 Option Units. Such option is granted solely for the
purpose of covering over-allotments in the sale of Firm Units and is exercisable
as provided in Section 4 hereof. Option Units shall be purchased severally for
the account of the Underwriters in proportion to the number of Firm Units set
opposite the names of such Underwriters in Schedule 1 hereto. The respective
purchase obligations of each Underwriter with respect to the Option Units shall
be adjusted by the Representatives so that no Underwriter shall be obligated to
purchase Option Units other than in 100 Unit amounts. The price of both the Firm
Units and any Option Units shall be $_____ per Unit.

         The Company shall not be obligated to deliver any of the Units to be
delivered on the First Delivery Date or the Second Delivery Date (as defined in
Section 4), as the case may be, except upon payment for all the Units to be
purchased on such Delivery Date as provided herein.

         3. Offering of Units by the Underwriters. Upon authorization by the
Representatives of the release of the Firm Units, the several Underwriters
propose to offer the Firm Units for sale upon the terms and conditions set forth
in the Prospectus.

         4. Delivery of and Payment for the Units. Delivery of and payment for
the Firm Units shall be made at the office of Lehman Brothers Inc. at 10:00
A.M., New York City time, on the fourth full business day following the date of
this Agreement or at such other date or place as shall be


                                      -11-
   12


determined by agreement between the Representatives and the Company. This date
and time are sometimes referred to as the "First Delivery Date." On the First
Delivery Date, the Company shall deliver or cause to be delivered certificates
representing the Firm Units to the Representatives for the account of each
Underwriter against payment to or upon the order of the Company of the purchase
price by wire transfer of immediately available funds. Time shall be of the
essence, and delivery at the time and place specified pursuant to this Agreement
is a further condition of the obligation of each Underwriter hereunder. Upon
delivery, the Firm Units shall be registered in such names and in such
denominations as the Representatives shall request in writing not less than two
full business days prior to the First Delivery Date. For the purpose of
expediting the checking and packaging of the certificates for the Firm Units,
the Company shall make the certificates representing the Firm Units available
for inspection by the Representatives in New York, New York, not later than 2:00
P.M., New York City time, on the business day prior to the First Delivery Date.

         At any time on or before the thirtieth day after the date of this
Agreement, the option granted in Section 2 may be exercised by written notice
being given to the Company by the Representatives. Such notice shall set forth
the aggregate number of Option Units as to which the option is being exercised,
the names in which the Option Units are to be registered, the denominations in
which the Option Units are to be issued and the date and time, as determined by
the Representatives, when the Option Units are to be delivered; provided,
however, that this date and time shall not be earlier than the First Delivery
Date nor earlier than the second business day after the date on which the option
shall have been exercised nor later than the fifth business day after the date
on which the option shall have been exercised. The date and time the Option
Units are delivered are sometimes referred to as the "Second Delivery Date," and
the First Delivery Date and the Second Delivery Date are sometimes each referred
to as a "Delivery Date."

         Delivery of and payment for the Option Units shall be made at the place
specified in the first sentence of the first paragraph of this Section 4 (or at
such other place as shall be determined by agreement between the Representatives
and the Company) at 10:00 A.M., New York City time, on the Second Delivery Date.
On the Second Delivery Date, the Company shall deliver or cause to be delivered
the certificates representing the Option Units to the Representatives for the
account of each Underwriter against payment to or upon the order of the Company
of the purchase price by wire transfer of immediately available funds. Time
shall be of the essence, and delivery at the time and place specified pursuant
to this Agreement is a further condition of the obligation of each Underwriter
hereunder. Upon delivery, the Option Units shall be registered in such names and
in such denominations as the Representatives shall request in the aforesaid
written notice. For the purpose of expediting the checking and packaging of the
certificates for the Option Units, the Company shall make the certificates
representing the Option Units available for inspection by the Representatives in
New York, New York, not later than 2:00 P.M., New York City time, on the
business day prior to the Second Delivery Date.

Prospectus as then amended or supplemented would include an untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were

reason it shall be necessary to amend or supplement the Prospectus in order to
comply with the Securities Act, to notify the Representatives and, upon their
request, to file such document and to prepare and furnish without charge to each
Underwriter and to any dealer in securities as many copies as the
Representatives may from time to time reasonably request of an amended or
supplemented Prospectus which will correct such statement or omission or effect
such compliance.

         (iv) To file promptly with the Commission any amendment to the
Registration Statement or the Prospectus or any supplement to the Prospectus
that may, in the reasonable judgment of the Company or the Representatives, be
required by the Securities Act or requested by the Commission.

         (v) Not to (A) file any amendment to the Registration Statement or make

sale under the securities laws of such jurisdictions as the Representatives may
request and to comply with such laws so as to permit the continuance of sales

complete the distribution of the Units; provided that in no event shall the
Company be obligated in connection therewith to qualify as a foreign corporation
or to execute a general consent to service of process.

         (vii) For a period of 180 days following the date of this Prospectus,
not to, directly or indirectly, (A) offer for sale, sell, pledge or otherwise
dispose of (or enter into any transaction or device which is designed to, or

future of) any Trust Units or any securities that are convertible into, or
exercisable or exchangeable for, or that represent the right to receive, Trust
Units, or sell or grant options, rights or warrants with respect to any Trust
Units or securities that are convertible into, or exercisable or exchangeable
for, or that represent the right to receive, Trust Units, except as disclosed in

satisfactory to the Representatives, to the effect that:

                  (i) Each of the Company and Statoil Energy Holdings has been
         duly incorporated and is validly existing as a corporation in good
         standing under the laws of the State of Delaware, with full corporate
         power and authority to own or lease its properties and conduct its

         counsel's knowledge, such jurisdictions are the only jurisdictions in
         which the character of the business conducted by the Company or Statoil
         Energy Holdings or the nature or location of the properties owned or
         leased by the Company or Statoil Energy Holdings makes such
         registration or qualification necessary, except where the failure to so
         register or qualify would not have a material adverse effect on the
         condition (financial or other), business, prospects, properties, net
         worth or results of operations of the Statoil Parties or the Trust.


                                      -16-

         the only jurisdictions in which the character of the business conducted
         by Statoil Energy or the nature or location of the properties owned or
         leased by it makes such registration or qualification necessary, except
         where the failure to so register or qualify would not have a material
         adverse effect on the condition (financial or otherwise), business,
         prospects, properties, net worth or results of operations of Statoil
         Parties or the Trust.

                  (v) Statoil Energy owns 100% of the outstanding common stock

         Holdings is on file in the office of the Secretary of State of the
         States of Delaware or the Commonwealth of Virginia or (b) otherwise

         applicable bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium or similar laws relating to or affecting creditors' rights
         generally and by general principles of equity (regardless of whether
         such enforceability is considered in a proceeding in equity or at law)
         and (B) public policy, applicable law relating to fiduciary duties and
         indemnification and an implied covenant of good faith and fair dealing.

         in the office of the Secretary of State of the State of Delaware or (B)

         payment by the Underwriters of the purchase price for the Units, the
         Underwriters will acquire the Units free of any adverse claim (as such
         term is defined in Article 8 of the New York Uniform Commercial Code),
         assuming that the Underwriters are acting in good faith and without
         notice of any adverse claim.

         granting such person the right to require the Company or the Trust to
         file a registration statement under the Securities Act with respect to
         any securities of the Company or the Trust owned or to be owned by such

         Statement or in any securities being registered pursuant to any other

         Securities Act.

                  (xii) None of the formation of the Trust by the execution and
         delivery of the Trust Agreement and the transfer of the Net Profits
         Interests by the Company to the Trust by the execution and delivery of
         the Conveyances, the sale of the Units by the Company hereunder, the
         compliance by the Statoil Parties with all of the provisions of this
         Agreement, the Trust Agreement and the Conveyances and the consummation
         of the transactions herein contemplated (A) constitutes or will
         constitute a violation of the certificate or articles of incorporation
         or bylaws or other organizational documents of any of the Statoil
         Parties or any of their subsidiaries, (B) constitutes or will
         constitute a breach or violation of, or a default under (or an event
         which, with notice or lapse of time or both, would constitute such an
         event), any agreement filed as an exhibit to the Registration Statement
         (other than the Trust Agreement) or any credit agreement, note

         governing indebtedness of any of the Statoil Parties or any of their
         subsidiaries, (C) violates or will violate any statute, law, rule or

         their properties in a proceeding to which any of them or their property
         is a party or (D)


                                      -18-
   19


         results or will result in the creation or imposition of any lien,
         charge or encumbrance upon any property or assets of any of the Statoil
         Parties or any of their subsidiaries.

                  (xiii) No permit, consent, approval, authorization, order,
         registration, filing, recordation or qualification of or with any

         Agreement, the Trust Agreement or the Conveyances, except as required
         under the Securities Act, the Exchange Act and state securities or
         "Blue Sky" laws.

                  (xiv) The statements in the Registration Statement and the

         Interests," "The Underlying Properties -- Title to Properties,"
         "Computation of Net Proceeds," "Description of the Trust Agreement,"

         conclusions, are accurate and complete in all material respects, and
         the Trust Units conform in all material respects to the description
         thereof contained in the Registration Statement and the Prospectus.

                  (xv) The opinion of Andrews & Kurth L.L.P. that is filed as
         Exhibit 8.1 to the Registration Statement is confirmed and the
         Underwriters may rely upon such opinion as if it were addressed to
         them.

                  (xvi) The Registration Statement was declared effective under
         the Securities Act on October ___, 1999; to the knowledge of such
         counsel, no stop order suspending the effectiveness of the Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or threatened by the Commission; and any required filing of
         the Prospectus pursuant to Rule 424(b) has been made in the manner and
         within the time period required by such Rule.

                  (xvii) The Registration Statement and the Prospectus (except
         for the financial statements and the notes and the schedules thereto,
         the reserve information contained therein and the other financial,
         statistical and accounting data included in the Registration Statement
         or the Prospectus, as to which such counsel need not express any
         opinion) comply as to form in all material respects with the
         requirements of the Act and the rules and regulations promulgated
         thereunder.

                  (xviii) To the knowledge of such counsel, (A) there is no
         legal or governmental proceeding pending or threatened to which any of

         respective properties is subject that is required to be disclosed in
         the Prospectus and is not so disclosed and (B) there are no agreements,
         contracts or other documents to which any of the Statoil Parties or the
         Trust is a party that are required to be


                                      -19-
   20


         described in the Registration Statement or the Prospectus or to be
         filed as exhibits to the Registration Statement that are not described
         or filed as required.

                  (xix) None of the Statoil Parties is an "investment company"
         as such term is defined in the Investment Company Act of 1940, as
         amended.

         In addition, such counsel shall state that they have participated in
conferences with officers and other representatives of the Statoil Parties and
the independent public accountants of the Company and the Trust and your
representatives, at which the contents of the Registration Statement and the
Prospectus and related matters were discussed, and although such counsel has not
independently verified, is not passing on, and is not assuming any
responsibility for the accuracy, completeness or fairness of the statements
contained in, the Registration Statement and the Prospectus (except to the
extent specified in the foregoing opinion), no facts have come to such counsel's
attention that lead such counsel to believe that the Registration Statement
(other than (i) the financial statements included therein, including the notes
and schedules thereto and the auditors' reports thereon, (ii) the reserve report
and other reserve information included therein and (iii) the other financial and
accounting data included therein, as to which such counsel need not comment), as
of its effective date 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 (other than
(i) the financial statements included therein, including the notes and schedules
thereto and the auditors' reports thereon, (ii) the reserve report and other
reserve information included therein and (iii) the other financial and
accounting data included therein, as to which such counsel need not comment), as
of its issue date and each Delivery Date contained an untrue statement of a
material fact or omitted to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                  In rendering such opinion, such counsel may (A) rely in
respect of matters of fact upon certificates of officers and employees of the
Statoil Parties and upon information obtained from public officials, (B) assume
that all documents submitted to them as originals are authentic, that all copies
submitted to them conform to the originals thereof, and that the signatures on

Statoil Parties, state that such opinions are based upon the opinions of Vorys,
Sater, Seymour, and Pease LLP and Goodwin and Goodwin provided pursuant to
Section 7 (g) below and upon certificates of foreign qualification or
registration provided by the Secretaries of State of the States of Delaware,
Indiana, Kentucky, Michigan, Mississippi, New Mexico, New York, Ohio,
Pennsylvania, Virginia and West Virginia (each of which shall be dated as of a
date not more than fourteen days prior to the Closing Date and shall be provided
to you), (E) state that they express no opinion with respect to the title of any
of the Underlying Properties or the Net Profits Interest and (F) state that they

         (e) Richards, Layton & Finger, P.A. shall have furnished to the
Representatives their written opinion, as counsel to the Trust, addressed to the
Underwriters and dated such Delivery Date, in form and substance reasonably
satisfactory to the Representatives, to the effect that:

                  (i) The Trust has been duly formed and is validly existing as
         a business trust within the meaning of the Delaware Business Trust Act
         (12 Del. Code Section 3801, et seq. (the "Delaware Business Trust
         Act")) and has full trust power and authority to own or lease its
         properties as described in the Prospectus.

                  (ii) There are 10,500,000 Trust Units representing units of
         undivided beneficial interest in the Trust authorized and issued under
         the Trust Agreement, all of which have been duly authorized and validly
         issued and are fully paid and nonassessable and conform to the
         descriptions thereof in the Prospectus.

                  (iii) Each of the Trust Agreement and the Conveyances,
         assuming the due authorization, execution and delivery thereof by the
         Company, is a valid and legally binding obligation of the Trustee and
         the Delaware Trustee enforceable against the Trustee and the Delaware
         Trustee in accordance with their respective terms, except as such
         enforceability may be limited by (A) applicable bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium or similar laws
         relating to or affecting creditors' rights generally and by general
         principles of equity (regardless of whether such enforceability is
         considered in a proceeding in equity or at law) and (B) public policy,
         applicable law relating to fiduciary duties and indemnification and an
         implied covenant of good faith and fair dealing.

                  (iv) All action of the Trustee, the Delaware Trustee and the
         Trust required under the Delaware Business Trust Act and the Trust
         Agreement with respect to the authorization and issuance of the Trust
         Units has been taken; Unitholders (as defined in the Trust Agreement)
         are entitled to the benefits of the Trust Agreement; except as
         described in the Prospectus under the heading "Description of the Trust
         Agreement -- Conditional Right of Repurchase," the issuance of such
         Trust Units is not subject to any preemptive rights or similar rights
         arising under the Delaware Business Trust Act or the Trust Agreement.

                  (v) None of the formation of the Trust by the execution and
         delivery of the Trust Agreement and the transfer of the Net Profits
         Interests by the Company to the Trust by the execution and delivery of
         the Conveyances, the sale of the Units by the Company hereunder, the
         compliance by the Statoil Parties with all of the provisions of this
         Agreement, the Trust Agreement and the Conveyances and the consummation
         by the Statoil Parties, the Trustee and the Delaware Trustee of the
         transactions herein contemplated (A) constitutes or will constitute a
         violation of the Trust Agreement or the Trust's certificate of trust,
         (B) constitutes or will constitute a breach or violation of, or a
         default under (or an event which, with notice or lapse of time or both,
         would constitute such an event), any credit agreement, note agreement,
         indenture, promissory note or any other agreement known to such counsel
         to which the Trust is a party or by which the Trust is bound, (C)
         violates or will violate any statute, law, rule or regulation or any
         order, judgment, decree or injunction of any court or governmental
         agency


                                      -21-
   22


         or body known to such counsel having jurisdiction over the Trust or (D)
         results or will result in the creation or imposition of any lien,
         charge or encumbrance upon any property or assets of any of the Trust.

                  (vi) Each Unitholder shall be entitled to the same limitation
         on personal liability as is extended to stockholders of private
         corporations for profit under the DGCL.

                  (vii) The Trust Agreement complies in all respects with the
         requirements of the Delaware Business Trust Act; the conditional right
         of repurchase of the Company provided for in Section 9.04 of the Trust
         Agreement is permitted by and lawful under the Delaware Business Trust
         Act and compliance by the Trustee with such Section 9.04 will not
         violate any fiduciary duty requirements of the Trustee under applicable
         provisions of Delaware law, including, without limitation, the Delaware
         Business Trust Act; compliance by the Trustee and the Delaware Trustee
         with Article XI of the Trust Agreement providing for arbitration will
         not violate any fiduciary duty requirements of the Trustee or the
         Delaware Trustee under applicable provisions of Delaware law,
         including, without limitation, the Delaware Business Trust Act.

                  (viii) Assuming that the Trustee conducts all of its
         activities with respect to the Trust at its offices in Forth Worth,
         Texas, (A) the Trustee is not required to qualify to do business as a
         trust company under 5 Del. Code Ann. Section 901, et seq. solely by
         reason of acting as a trustee of the Trust, (B) no consent, approval,
         authorization or filing is required under any other law or any rule or
         regulation of the State of Delaware in order to permit the Trustee to
         act as Trustee of the Trust, and (C) the compliance by the Trustee with
         the provisions of the Trust Agreement will not result in the violation
         of any statute, rule or regulation of the State of Delaware applicable
         to the Trust.

                  (ix) The specimen temporary certificate for the Trust Units
         and the specimen definitive certificate for the Trust Units are in
         proper legal form.

In rendering such opinion, such counsel may (A) rely in respect of matters of
fact upon certificates of officers and employees of the Statoil Parties and upon
information obtained from public officials, (B) assume that all documents
submitted to them as originals are authentic, that all copies submitted to them
conform to the originals thereof, and that the signatures on all documents
examined by them are genuine and (C) state that their opinion is limited to the
laws of the State of Delaware.

         (f) Kerry W. Eckstein shall have furnished to the Representatives his
written opinion, as General Counsel of the Company, addressed to the
Underwriters and dated such Delivery Date, in form and substance reasonably
satisfactory to the Representatives, to the effect that:

                  (i) None of the formation of the Trust by the execution and
         delivery of the Trust Agreement and the transfer of the Net Profits
         Interests by the Company to the Trust by the execution and delivery of
         the Conveyances, the sale of the Units by the Company hereunder, the
         compliance by the Statoil Parties and the Trust with all of the
         provisions of this


                                      -22-
   23


         Agreement, the Trust Agreement and the Conveyances and the consummation
         of the transactions herein contemplated (A) constitutes or will
         constitute a breach or violation of, or a default under (or an event
         which, with notice or lapse of time or both, would constitute such an
         event), any indenture, mortgage, deed of trust, loan agreement, lease
         or other agreement or instrument known to such counsel to which any of
         the Statoil Parties or any of their subsidiaries or the Trust is a
         party or by which any of the Statoil Parties or any of their
         subsidiaries or the Trust is bound or to which any of the property or
         assets of any of the Statoil Parties or any of their subsidiaries or
         the Net Profit Interests is subject (other than any agreement filed as
         an exhibit to the Registration Statement or any credit agreement, note
         agreement, indenture, promissory note or other agreement evidencing or
         governing indebtedness of any of the Statoil Parties or their
         subsidiaries) or (B) violates or will violate any order, judgment,
         decree or injunction of any court or governmental agency or body known
         to such counsel directed to any of the Statoil Parties or any of their
         subsidiaries or the Trust or any of their properties in a proceeding to
         which any of them or their property is a party.

                  (ii) All consents, approvals, authorizations and orders
         necessary for the transfer of the Net Profits Interests to the Trust as
         described in the Prospectus have been obtained and such transfer has
         not had the effect of creating any lien, encumbrance, security
         interest, equity, charge or claim of any kind in favor of any person
         with respect to any of the Net Profits Interests (including any
         preferential right of purchase, or, with respect to any properties in
         which the Company has acted as operator, any right to remove the
         Company as operator) except to the extent such rights have been validly
         waived in writing.

                  (iii) To the knowledge of such counsel, none of the Statoil
         Parties nor any of their subsidiaries is in (A) violation of its
         certificate or articles of incorporation or bylaws or other
         organizational documents, or of any law, statute, ordinance,
         administrative or governmental rule or regulation applicable to it or
         of any order, judgment, decree or injunction of any court or
         governmental agency or body having jurisdiction over it, or (B) breach,
         default (or an event which, with notice or lapse of time or both, would
         constitute such an event) or violation in the performance of any
         obligation, agreement or condition contained in any bond, debenture,
         note or any other evidence of indebtedness or in any agreement,
         indenture, lease or other instrument to which it is a party or by which
         it or any of its properties may be bound, which breach, default or
         violation would, if continued, have a material adverse effect on the
         condition (financial or other), business, prospects, properties, net
         worth or results of operations of the Statoil Parties, taken as a
         whole, or the Trust or could materially impair the ability of any of
         the Statoil Parties or the Trust to perform its obligations under this
         Agreement, the Trust Agreement or the Conveyances.

                  (iv) To the knowledge of such counsel, the Company and its
         subsidiaries have such permits, consents, licenses, franchises and
         authorizations of governmental or regulatory authorities ("permits") as
         are necessary to own or lease their properties and to conduct their
         business in the manner described in the Prospectus, subject to such
         qualifications as may be set forth in the Prospectus and except for
         such permits which, if not obtained, would not have, individually or in
         the aggregate, a material adverse effect upon the ability of the
         Company and


                                      -23-
   24


         its subsidiaries, considered as a whole, to conduct their businesses in
         all material respects as currently conducted and as contemplated by the
         Prospectus to be conducted; and, to the knowledge of such counsel,
         neither the Company nor its subsidiaries has received any notice of
         proceedings relating to the revocation or modification of any such
         permits which, individually or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would reasonably be expected
         to have a material adverse effect upon the operations conducted by the
         Trust.

                  (v) Except as described in the Prospectus, to the knowledge of
         such counsel, there is no litigation, proceeding or governmental
         investigation pending or threatened against any of the Statoil Parties
         or their subsidiaries or the Trust which, if adversely determined to
         such party, is reasonably likely to have a material adverse effect on
         the financial condition, business, properties or results of operations
         of the Trust.

         In addition, such counsel shall state that he has participated in
conferences with officers and other representatives of the Statoil Parties and
the independent public accountants of the Company and the Trust and your
representatives, at which the contents of the Registration Statement and the
Prospectus and related matters were discussed, and although such counsel has not
independently verified, is not passing on, and is not assuming any
responsibility for the accuracy, completeness or fairness of the statements
contained in, the Registration Statement and the Prospectus, no facts have come
to such counsel's attention that lead such counsel to believe that the
Registration Statement (other than (i) the financial statements included
therein, including the notes and schedules thereto and the auditors' reports
thereon, (ii) the reserve report and other reserve information included therein
and (iii) the other financial and accounting data included therein, as to which
such counsel need not comment), as of its effective date 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 (other than (i) the financial statements included therein,
including the notes and schedules thereto and the auditors' reports thereon,
(ii) the reserve report and other reserve information included therein and (iii)
the other financial and accounting data included therein, as to which such
counsel need not comment), as of its issue date and each Delivery Date contained
an untrue statement of a material fact or omitted to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

                  In rendering such opinion, such counsel may (A) rely in
respect of matters of fact upon certificates of officers and employees of the
Statoil Parties and upon information obtained from public officials, (B) assume
that all documents submitted to him as originals are authentic, that all copies
submitted to him conform to the originals thereof, and that the signatures on
all documents examined by him are genuine, (C) state that such opinions are
limited to federal laws, the DGCL and the laws of the State of Virginia, (D)
state that he expresses no opinion with respect to the title of any of the
Underlying Properties or the Net Profits Interest and (E) state that he
expresses no opinion with respect to state or local taxes or tax statutes.

         (g) Each of Vorys, Sater, Seymour, and Pease LLP, special local counsel
for the Company and the Trust in the State of Kentucky, and Goodwin and Goodwin,
special local counsel for the Company and the Trust in the State of West
Virginia, shall have furnished to the Representatives its written opinion,
addressed to the Underwriters and dated such Delivery Date, in form and
substance reasonably satisfactory to the Representatives, to the effect that:

                  (i) The Company has been duly registered or qualified as a
         foreign corporation for the transaction of business and is in good
         standing under the laws of [insert applicable state].

                  (ii) Neither the Trust, the Trustee nor the Delaware Trustee
         is required to qualify to transact business or appoint an agent for
         service of process in [insert applicable state] as a result of the
         ownership, operation or activities of the Trust, the Trustee or the
         Delaware Trustee with respect to the Trust, and the activities of the
         Trustee and the Delaware Trustee pursuant to the Trust Agreement will
         not require the appointment of an ancillary trustee in the State of
         [insert applicable state].

                  (iii) The [applicable] Conveyance, assuming the due
         authorization, execution and delivery thereof by the parties thereto,
         is the valid and legally binding obligation of the Company enforceable
         against the Company in accordance with its terms, except as such
         enforceability of the [applicable] Conveyance may be limited by (A)
         applicable bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium or similar laws relating to or affecting creditors' rights
         generally and by general principles of equity (regardless of whether
         such enforceability is considered in a proceeding in equity or at law)
         and (B) public policy, applicable law relating to fiduciary duties and
         indemnification and an implied covenant of good faith and fair dealing.
         A court of competent jurisdiction of [insert applicable state] should

as of which specified financial information is given in the Prospectus, as of a
date not more than five days prior to the date hereof), the conclusions and
findings of such firm with respect to the financial information and other
matters ordinarily covered by accountants' "comfort letter" to underwriters in
connection with registered public offerings.

         (n) With respect to the letter of Ernst & Young referred to in the

contemplated in the Prospectus nor (ii) since such date there shall not have
been any change in the capital stock, short-term debt or long-term debt of the
Company, its subsidiaries or the Trust or any change, or any development
involving a prospective change, in or affecting the general affairs, management,
financial position, stockholders' equity or results of operations of the
Company, its subsidiaries or the Trust, otherwise than as set forth or
contemplated in the Prospectus, the effect of which, in any such case described
in clause (i) or (ii), is, in the judgment of the Representatives, so material

         (q) Subsequent to the execution and delivery of this Agreement there

         (a) The Company and the Trust (solely from the assets of the Trust and
without liability or obligation of the Trustee or any Unitholder), jointly and
severally, shall indemnify and hold harmless each Underwriter, its officers and
employees and each person, if any, who controls any Underwriter within the
meaning of the Securities Act, from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to
purchases and sales of Units), to which that Underwriter, officer, employee or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus or in any amendment or supplement thereto, (ii) the omission or
alleged omission to state in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or in any amendment or supplement thereto, any

failure to act by any Underwriter in connection with, or relating in any manner
to, the Units or the offering contemplated hereby, and which is included as part
of or referred to in any loss, claim, damage, liability or action arising out of
or based upon matters covered by clause (i) or (ii) above (provided that neither
the Company nor the Trust shall be liable under this clause (iii) to

                                      -31-
   32


the extent that it is determined in a final judgment by a court of competent
jurisdiction that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be taken
by such Underwriter through its gross negligence or willful misconduct), and
shall reimburse each Underwriter and each such officer, employee or controlling
person promptly upon demand for any legal or other expenses reasonably incurred
by that Underwriter, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that neither the Company nor the Trust shall be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus, or in any such amendment or supplement, in reliance upon and
in conformity with written information concerning such Underwriter furnished to
the Company through the Representatives by or on behalf of any Underwriter
specifically for inclusion therein which information consists solely of the
information specified in Section 8(e). The foregoing indemnity agreement is in
addition to any liability which the Company and the Trust may otherwise have to
any Underwriter or to any officer, employee or controlling person of that
Underwriter.

         (b) Each Underwriter, severally and not jointly, shall indemnify and
hold harmless the Company, the Trust and the Trustee, their officers and
employees, each of their directors (including any person who, with his or her
consent, is named in the Registration Statement as about to become a director of
the Company), and each person, if any, who controls the Company, the Trust or
the Trustee within the meaning of the Securities Act, from and against any loss,
claim, damage or liability, joint or several, or any action in respect thereof,
to which the Company and the Trust or any such director, officer or controlling
person may become subject, under the Securities Act or otherwise, insofar as
such loss, claim, damage, liability or action arises out of, or is based upon,
(i) any untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus or in any amendment or supplement thereto, or (ii) the omission or
alleged omission to state in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or in any amendment or supplement thereto, any
material fact required to be stated therein or necessary to make the statements
therein not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information concerning such
Underwriter furnished to the Company, the Trust or the Trustee through the
Representatives by or on behalf of that Underwriter specifically for inclusion
therein, and shall reimburse the Company, the Trust and the Trustee and any such
director, officer or controlling person for any legal or other expenses
reasonably incurred by the Company, the Trust or the Trustee or any such
director, officer or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred. The foregoing indemnity agreement is in
addition to any liability which any Underwriter may otherwise have to the
Company, the Trust or the Trustee or any such director, officer, employee or
controlling person.

         (c) Promptly after receipt by an indemnified party under this Section 8
of notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in


                                      -32-
   33


writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure, and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 8.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party. After notice from
the indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of such indemnified party unless (i) the
employment of such counsel has been specifically authorized in writing by the
indemnifying party, (ii) the indemnifying party shall have failed to assume the
defense and employ counsel or (iii) the named parties to any such action
(including any impleaded parties) include both such indemnified party and the
indemnifying party and such indemnified party shall have been advised by such
counsel that there may be one or more legal defenses available to it which are
different from or additional to those available to the indemnifying party (in
which case the indemnifying party shall not have the right to assume the defense
of such action on behalf of such indemnified party and the fees and expenses of
such separate counsel shall be paid by the indemnifying party). No indemnifying
party shall, in connection with any one such action or proceeding or separate
but substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) at any time for such indemnified
party, which firm shall be designated by the indemnified party. No indemnifying
party shall (i) without the prior written consent of the indemnified parties
(which consent shall not be unreasonably withheld), settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified parties are
actual or potential parties to such claim or action) unless such settlement,
compromise or consent includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit or proceeding,
or (ii) be liable for any settlement of any such action effected without its
written consent (which consent shall not be unreasonably withheld), but if
settled with the consent of the indemnifying party or if there be a final
judgment of the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss or
liability by reason of such settlement or judgment.

         (d) If the indemnification provided for in this Section 8 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability,
or any action in respect thereof, referred to therein, then each indemnifying
party shall, in lieu of indemnifying such indemnified party, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability, or action


                                      -33-

in respect thereof, (i) in such proportion as shall be appropriate to reflect
the relative benefits received by the Company and the Trust, on the one hand,
and the Underwriters on the other from the offering of the Units 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 and
the Trust, on the one hand, and the Underwriters on the other, with respect to
the statements or omissions which resulted in such loss, claim, damage or
liability, or action in respect thereof, as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Trust, on
the one hand, and the Underwriters on the other, with respect to such offering
shall be deemed to be in the same proportion as the total net proceeds from the
offering of the Units purchased under this Agreement (before deducting expenses)
received by the Company, on the one hand, and the total underwriting discounts
and commissions received by the Underwriters with respect to the Units purchased
under this Agreement, on the other hand, bear to the total gross proceeds from
the offering of the Units under this Agreement, in each case as set forth in the
table on the cover page of the Prospectus. The relative fault shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company and the Trust or the Underwriters, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Trust and the Underwriters agree that it would not be just and equitable if
contributions pursuant to this Section 8 were to be determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 8 shall be deemed
to include, for purposes of this Section 8(d), any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 8(d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Units underwritten by
it and distributed to the public was offered to the public exceeds the amount of
any damages which such Underwriter has otherwise paid or becomes liable to pay
by reason of any untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute as provided in this Section 8(d) are
several in proportion to their respective underwriting obligations and not
joint.

         (e) The Underwriters severally confirm and the Company and the Trust
acknowledge that the statements with respect to the public offering of the Units
by the Underwriters set forth on the cover page of the Prospectus, the
information in the chart in the first paragraph under the caption "Underwriting"
in the Prospectus, the concession and reallowance figures appearing in the
fourth paragraph under the caption "Underwriting" in the Prospectus and the
statements in the eighth, ninth, tenth, eleventh, twelfth, thirteenth (to the
extent relating to the Underwriters), fourteenth and sixteenth paragraphs under
the caption "Underwriting" in the Prospectus are correct and constitute the only
information concerning such Underwriters furnished in writing to the Company or
the Trust by or on behalf of the Underwriters specifically for inclusion in the
Registration Statement and the Prospectus.

         9. Defaulting Underwriters.

         If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Underwriters shall be obligated to purchase the Units which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of Firm Units set opposite the name
of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the
total number of Firm Units set opposite the names of all the remaining
non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the
remaining non-defaulting Underwriters shall not be obligated to purchase any of
the Units on such Delivery Date if the total number of Units which the
defaulting Underwriter or Underwriters agreed but failed to purchase on such
date exceeds 9.09% of the total number of Units to be purchased on such Delivery
Date, and any remaining non-defaulting Underwriter shall not be obligated to
purchase more than 110% of the number of the Units which it agreed to purchase
on such Delivery Date pursuant to the terms of Section 2. If the foregoing
maximums are exceeded, the remaining non-defaulting Underwriters, or those other
underwriters satisfactory to the Representatives who so agree, shall have the
right, but shall not be obligated, to purchase, in such proportion as may be
agreed upon among them, all the Units to be purchased on such Delivery Date. If
the remaining Underwriters or other underwriters satisfactory to the
Representatives do not elect to purchase the Units which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such Delivery Date,
this Agreement (or, with respect to the Second Delivery Date, the obligation of
the Underwriters to purchase, and of the Company to sell, the Option Units)
shall terminate without liability on the part of any non-defaulting Underwriter,
the Company or the Trust except that the Company will continue to be liable for
the payment of expenses to the extent set forth in Sections 6 and 11. As used in
this Agreement, the term "Underwriter" includes, for all purposes of this
Agreement unless the context requires otherwise, any party not listed in
Schedule 1 hereto who, pursuant to this Section 9, purchases Firm Units which a
defaulting Underwriter agreed but failed to purchase.

         Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages, including expenses paid by the
Company pursuant to Sections 6 and 11, caused by its default. If other
underwriters are obligated or agree to purchase the Units of a defaulting or
withdrawing Underwriter, either the Representatives or the Company may postpone
the Delivery Date for up to seven full business days in order to effect any
changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

         10. Termination. The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the Company
prior to delivery of and payment for the Firm Units if, prior to that time, any
of the events described in Section 7(p) or Section 7(q) shall have occurred or
if the Underwriters shall decline to purchase the Units for any reason permitted
under this Agreement.

         11. Reimbursement of Underwriters' Expenses. If the Company shall fail
to tender the Units for delivery to the Underwriters by reason of any failure,
refusal or inability on the part of the Company or the Trust to perform any
agreement on its part to be performed, or because any other


                                      -35-
   36


condition of the Underwriters' obligations hereunder required to be fulfilled by
the Company or the Trust is not fulfilled, the Company and the Trust will
reimburse the Underwriters for all reasonable out-of-pocket expenses (including
fees and disbursements of counsel) incurred by the Underwriters in connection
with this Agreement and the proposed purchase of the Units, and upon demand the
Company and the Trust shall pay the full amount thereof to the Representatives.
If this Agreement is terminated pursuant to Section 9 by reason of the default
of one or more Underwriters, neither the Company nor the Trust shall be
obligated to reimburse any defaulting Underwriter on account of those expenses.

         12. Notices, etc. Any notice, consent, request, instruction, approval
and other communication provided for herein shall be in writing, shall be
delivered or sent by mail, telex or facsimile transmission and shall be deemed
validly given, made or served (a) on the date on which it is delivered

to the Director of Litigation, Office of the General Counsel, Lehman Brothers
Inc., 3 World Financial Center, 10th Floor, New York, New York 10285; provided,
however, that any notice to an Underwriter pursuant to Section 8(c) shall be

at its address set forth in its acceptance telex to the Representatives, which
address will be supplied to any other party hereto by the Representatives upon
request. Any such statements, requests, notices or agreements shall take effect
at the time of receipt thereof. The Company shall be entitled to act and rely
upon any request, consent, notice or agreement given or made on behalf of the
Underwriters by Lehman Brothers Inc. on behalf of the Representatives.

         13. Persons Entitled to Benefit of Agreement. This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Company, the
Trust and their respective successors. This Agreement and the terms and
provisions hereof are for the sole benefit of only those persons, except that

and the Trust contained in this Agreement shall also be deemed to be for the
benefit of the person or persons, if any, who control any Underwriter within the

Trust within the meaning of Section 15 of the Securities Act. Nothing in this
Agreement is intended or shall be construed to give any person, other than the
persons referred to in this Section 13, any legal or equitable right, remedy or
claim under or in respect of this Agreement or any provision contained herein.

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

         15. Definition of the Terms "Business Day" and "Subsidiary". For
purposes of this Agreement, (a) "business day" means any day on which the NYSE
is open for trading, and (b) "subsidiary" has the meaning set forth in Rule 405
of the Rules and Regulations.

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

         17. Counterparts. This Agreement may be executed in one or more

counterparts shall each be deemed to be an original but all such counterparts
