     The undersigned, Evergreen Resources, Inc., a Colorado corporation (the
"Company"), hereby addresses you as the underwriters (the "Underwriters") and
hereby confirms its agreement with the Underwriters as follows:

     1. DESCRIPTION OF SHARES. The Company proposes to issue and sell to the
Underwriters 2,840,000 shares of its common stock, no par value per share (the
"Common Stock"), as set forth on Schedule I hereto (such 2,840,000 shares of
Common Stock are herein collectively referred to as the "Firm Shares"). Solely
for the purpose of covering over-allotments in the sale of the Firm Shares, the
Company further proposes to grant to the Underwriters the right to purchase up
to an additional 426,000 shares of Common Stock (the "Option Shares"), as
provided in Section 3 of this Agreement. The Firm Shares and the Option Shares
are herein sometimes referred to as the "Shares" and are more fully described in
the Prospectus hereinafter defined.

     2. PURCHASE, SALE AND DELIVERY OF FIRM SHARES. On the basis of the
representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and each such Underwriter agrees, severally and not jointly,
(a) to purchase from the Company, at a purchase price of $27.935 per share
(which represents the public offering price of $29.375 per share minus the
underwriting discount of $1.44 per share), the number of Firm Shares set
forth opposite the name of such Underwriter in Schedule I hereto and (b) to
purchase from the Company any additional number

<PAGE>

of Option Shares that such Underwriter may become obligated to purchase pursuant
to Section 3 hereof.

     The Company will deliver the Firm Shares to the Underwriters, against
payment of the purchase price therefor in immediately available funds by wire
transfer, prior to 1:00 p.m., New York time, on November 8, 2000, or at such
other time and date as may be agreed upon in writing by the Company and A.G.
Edwards & Sons, Inc. Delivery of the Firm Shares will be in book-entry form
through the facilities of The Depository Trust Company, New York, New York
("DTC"). Delivery of the documents required by Section 6 hereof with respect to
the Shares shall be made at such time and date at the offices of Vinson & Elkins
L.L.P., The Willard Office Building, 1455 Pennsylvania Avenue, N.W., Suite 700,
Washington, D.C. 20004, or at such other location as may be agreed upon in
writing by the Company and A.G. Edwards & Sons, Inc. For purposes of this
Agreement, "Closing Date" shall mean the hour and date of such delivery and
payment.

     The Company will cause its transfer agent to deposit as original issue the
Firm Shares pursuant to the Full Fast Delivery Program of DTC.

     It is understood that an Underwriter, individually, may (but shall not be
obligated to) make payment on behalf of the other Underwriters whose funds shall
not have been received prior to the Closing Date for Shares to be purchased by
such Underwriter. Any such payment by an Underwriter shall not relieve the other
Underwriters of any of their obligations hereunder.

     It is understood that the Underwriters propose to offer the Shares to the
public upon the terms and conditions set forth in the Registration Statement
hereinafter defined.

     3. PURCHASE, SALE AND DELIVERY OF THE OPTION SHARES. The Company hereby
grants an option to the Underwriters to purchase from the Company up to 426,000
Option Shares on the same terms and conditions as the Firm Shares; provided,
however, that such option may be exercised only for the purpose of covering any
over-allotments that may be made by them in the sale of the Firm Shares. No
Option Shares shall be sold or delivered unless the Firm Shares previously have
been, or simultaneously are, sold and delivered.

     The option is exercisable by the Underwriters at any time, and from time to
time, before the expiration of 30 days from the date of the Prospectus (or, if
such 30th day shall be a Saturday or Sunday or a holiday, on the next day
thereafter when the New York Stock Exchange is open for trading) (the "Option
Period"), for the purchase of all or part of the Option Shares covered thereby,
by notice given by the Underwriters to the Company in the manner provided in
Section 12 hereof, setting forth the number of Option Shares as to which the
Underwriters are exercising the option, and the date of delivery of said Option
Shares, which date shall not be more than five business days after such notice
unless otherwise agreed to by the parties. The Underwriters may


                                       2
<PAGE>

terminate the option at any time, as to any unexercised portion thereof, by
giving written notice to the Company to such effect.

     The Underwriters shall make such allocation of the Option Shares among them
as may be required to eliminate purchases of fractional Shares.

     The Company will deliver the Option Shares to the Underwriters, in
book-entry form through the facilities of DTC (or at such other place as the
Company and A.G. Edwards & Sons, Inc. may mutually agree upon), against payment
by the Underwriters of the per share purchase price to the Company by wire
transfer of immediately available funds. Such payment and delivery shall be made
at 10:00 a.m., New York time, on the date designated in the notice given by the
Underwriters as above provided for (which may be the same as the Closing Date),
unless some other date and time are agreed upon, which date and time of payment
and delivery are called the "Option Closing Date." On the Option Closing Date,
the Company shall provide the Underwriters such representations, warranties,
agreements, opinions, letters, certificates and covenants with respect to the
Option Shares as are required to be delivered on the Closing Date with respect
to the Firm Shares.

     The Company will cause its transfer agent to deposit as original issue the
Option Shares pursuant to the Full Fast Delivery Program of DTC.

     4. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY. (a) The
Company represents and warrants to and agrees with each Underwriter that:

          (i) A registration statement (Registration No. 333-78203) on Form S-3
     with respect to the Shares, including a preliminary prospectus, and such
     amendments to such registration statement as may have been required to the
     date of this Agreement, has been prepared by the Company pursuant to and in
     conformity with the requirements of the Securities Act of 1933, as amended
     (the "1933 Act"), and the rules and regulations thereunder (the "1933 Act
     Rules and Regulations") of the Securities and Exchange Commission (the
     "SEC") and has been filed with and declared effective by the SEC under the
     1933 Act. The Company meets the requirements for use of Form S-3 under the
     1933 Act. Copies of such registration statement, including any amendments
     thereto, the base prospectus, dated May 24, 1999, and preliminary
     prospectus supplement relating to the Shares, dated October 13, 2000 (such
     preliminary prospectus supplement, including the base prospectus, being
     referred to herein together as the "Preliminary Prospectus"), and the
     exhibits, financial statements and schedules thereto have heretofore been
     delivered by the Company to the Underwriters. A final prospectus and
     prospectus supplement relating to the Shares, the terms of the offering
     thereof and the other matters set forth therein has been prepared and will
     be promptly filed by the Company with the SEC pursuant to Rule 424(b) of
     the 1933 Act Rules and Regulations. The term "Registration Statement" as


                                       3
<PAGE>

     used herein means the registration statement as amended at the time it
     became effective under the 1933 Act and at the time any post-effective
     amendments thereto (including the filing of the Company's most recent
     Annual Report on Form 10-K with the Commission (the "Annual Report on Form
     10-K")) became effective (the "Effective Date"), including financial
     statements and all exhibits and all documents incorporated by reference
     therein pursuant to Item 12 of Form S-3 under the 1933 Act. If it is
     contemplated, at the time this Agreement is executed, that a post-effective
     amendment to such registration statement will be filed and must be declared
     effective before the offering of Shares may commence, the term
     "Registration Statement" as used herein means the registration statement as
     amended by said post-effective amendment. If an abbreviated registration
     statement is prepared and filed with the SEC in accordance with Rule 462(b)
     under the 1933 Act (an "Abbreviated Registration Statement"), the term
     "Registration Statement" as used in this Agreement includes the Abbreviated
     Registration Statement. The term "Prospectus" as used herein means the
     final prospectus and prospectus supplement relating to the Shares as first
     filed with the SEC pursuant to Rule 424(b) of the 1933 Act Rules and
     Regulations, including the documents incorporated by reference therein
     pursuant to Item 12 of Form S-3 under the 1933 Act. For purposes of this
     Agreement, the words "amend," "amendment," "amended," "supplement" or
     "supplemented" with respect to the Registration Statement or the Prospectus
     shall mean amendments to the Registration Statement or supplements to the
     Prospectus, as the case may be, as well as documents filed after the date
     of this Agreement and prior to the completion of the distribution of the
     Shares and incorporated by reference therein as described above.

          (ii) Neither the SEC nor any state or other jurisdiction or other
     regulatory body has issued, and neither is, to the knowledge of the
     Company, threatening to issue, any stop order under the 1933 Act or other
     order suspending the effectiveness of the Registration Statement (as
     amended or supplemented) or preventing or suspending the use of any
     Preliminary Prospectus or the Prospectus or suspending the qualification or
     registration of the Shares for offering or sale in any jurisdiction nor
     instituted or, to the knowledge of the Company, threatened to institute
     proceedings for any such purpose. Each Preliminary Prospectus at its date
     of issue, the Registration Statement and the Prospectus and any amendments
     or supplements thereto contain or will contain, as the case may be, all
     statements that are required to be stated therein by, and in all material
     respects conform or will conform, as the case may be, to the requirements
     of, the 1933 Act and the 1933 Act Rules and Regulations. None of (x) the
     Registration Statement, as of the Effective Date, (y) any amendment
     thereto, as of its effective date, or (z) any Abbreviated Registration
     Statement, as of its filing date, contains or will contain, as the case may
     be, any untrue statement of a material fact or omits or will omit to state
     any material fact required to be stated therein or necessary to make the
     statements therein, not misleading; and neither any Preliminary Prospectus,
     the Prospectus nor any supplement thereto contains or will contain, as the
     case may be, any untrue statement of a material


                                       4
<PAGE>

     fact or omits or will 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; provided, however, that the Company makes no
     representation or warranty as to information contained in or omitted from
     the Registration Statement or the Prospectus, or any such amendment or
     supplement, in reliance upon, and in conformity with, written information
     relating to the Underwriters furnished to the Company by A.G. Edwards &
     Sons, Inc. on behalf of the Underwriters expressly for use in the
     preparation thereof (as provided in Section 13 hereof). There is no
     contract or document required to be described in the Registration Statement
     or Prospectus or to be filed as an exhibit to the Registration Statement
     that is not described or filed as required. The documents incorporated by
     reference in the Prospectus pursuant to Item 12 of Form S-3 under the 1933
     Act, at the time they were filed with the SEC, complied in all material
     respects with the requirements of the Securities Exchange Act of 1934, as
     amended (the "1934 Act"), and the rules and regulations adopted by the SEC
     thereunder (the "1934 Act Rules and Regulations"). Any future documents
     incorporated by reference so filed, when they are filed, will comply in all
     material respects with the requirements of the 1934 Act and the 1934 Act
     Rules and Regulations; no such incorporated document contained or will
     contain any untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; and, when read together and with the other
     information in the Prospectus, at the time the Registration Statement
     became effective and at the Closing Date, each such incorporated document
     did not or will not, as the case may be, 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.

          (iii) This Agreement has been duly authorized, executed and delivered
     by the Company and constitutes a valid and legally binding obligation of
     the Company enforceable against the Company in accordance with its terms,
     except as enforceability may be limited by bankruptcy, insolvency,
     fraudulent conveyance, reorganization, moratorium and other similar laws
     relating to or affecting creditors' rights generally and by general
     principles of equity and except as rights to indemnity and contribution may
     be limited under applicable law (the "Exceptions").

          (iv) The Company and its subsidiaries have been duly organized and are
     validly existing as companies in good standing under the laws of the states
     or other jurisdictions in which they are incorporated or organized, as the
     case may be, with full power and authority (corporate and other) to own,
     lease and operate their properties and conduct their businesses as
     described in the Prospectus and, with respect to the Company, to execute
     and deliver, and perform the Company's obligations under, this Agreement;
     the Company and its subsidiaries are duly qualified to do business as
     foreign companies in good standing in each state or other jurisdiction in
     which their ownership or leasing of


                                       5
<PAGE>

     property or conduct of business legally requires such qualification, except
     where the failure to be so qualified, individually or in the aggregate,
     would not have a Material Adverse Effect. The term "Material Adverse
     Effect" as used herein means any material adverse effect on the condition
     (financial or other), net worth, business, management, prospects, results
     of operations or cash flow of the Company and its subsidiaries, taken as a
     whole.

          (v) Except as contemplated in the Prospectus (or, if the Prospectus is
     not in existence, the most recent Preliminary Prospectus), neither the
     Company nor any of its subsidiaries has sustained since the date of the
     latest audited financial statements included or incorporated by reference
     in the Prospectus (or Preliminary 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. Subsequent to the respective
     dates as of which information is given in the Registration Statement and
     the Prospectus (or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus), (1) the Company and its subsidiaries have not
     incurred any material liability or obligation, direct or contingent, nor
     entered into any material transaction not in the ordinary course of
     business; (2) the Company has not purchased any of its outstanding capital
     stock, nor declared, paid or otherwise made any dividend or distribution of
     any kind on its capital stock; (3) there has not been any change in the
     capital stock, short-term debt or long-term debt of the Company or any of
     its subsidiaries (except that (A) the long-term debt of the Company has
     increased from approximately $122 million to approximately $127 million,
     (B) the Company has issued approximately 20,000 shares of Common Stock and
     (C) the Company has granted options to acquire approximately 150,000 shares
     of Common Stock); and (4) there has not been any material adverse change,
     or any development involving a prospective material adverse change, in or
     affecting the business, management, financial position, stockholders'
     equity or results of operations of the Company and its subsidiaries taken
     as a whole, except in each case as described in or contemplated by the
     Prospectus (or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus)

          (vi) The issuance and sale of the Shares and the execution, delivery
     and performance by the Company of this Agreement, and the consummation of
     the transactions herein contemplated, will not conflict with or result in a
     breach or violation of any of the terms or provisions of, or constitute a
     default under, or result in the creation or imposition of any lien, charge
     or encumbrance upon any properties or assets of the Company or any of its
     subsidiaries under, any indenture, mortgage, deed of trust, loan agreement
     or other agreement or instrument to which the Company or any of its
     subsidiaries is a party or by which the Company or any of its subsidiaries
     is bound or to which any of the properties or assets of the Company or any
     of its subsidiaries is subject, except to such extent as, individually or
     in the aggregate, does not have a Material


                                       6
<PAGE>

     Adverse Effect, nor will such action result in any violation of the
     provisions of the Company's articles of incorporation or bylaws or any
     statute, rule, regulation or other law, or any order or judgment, of any
     court or governmental agency or body having jurisdiction over the Company
     or any of its subsidiaries or any of their properties; and no consent,
     approval, authorization, order, registration or qualification of or with
     any such court or governmental agency or body is required for the
     execution, delivery and performance of this Agreement, the issuance and
     sale of the Shares or the consummation of the transactions contemplated
     hereby, except such as have been, or will be prior to the Closing Date,
     obtained under the 1933 Act or as may be required by the National
     Association of Securities Dealers, Inc. (the "NASD") and such consents,
     approvals, authorizations, registrations or qualifications as may be
     required under state securities or blue sky laws in connection with the
     purchase and distribution of the Shares by the Underwriters.

          (vii) The Company has duly and validly authorized capital stock as set
     forth in the Prospectus; all outstanding shares of Common Stock and the
     Shares conform, or when issued will conform, to the description thereof in
     the Prospectus and have been, or, when issued and paid for in the manner
     described herein will be, duly authorized, validly issued, fully paid and
     non-assessable; and the issuance of the Shares is not subject to preemptive
     or other similar rights, or any restriction upon the voting or transfer
     thereof pursuant to applicable law or the Company's articles of
     incorporation, bylaws or governing documents or any agreement to which the
     Company or any of its subsidiaries is a party or by which any of them may
     be bound. All corporate action required to be taken by the Company for the
     authorization, issuance and sale of the Shares has been duly and validly
     taken. Except as disclosed in the Prospectus, there are no outstanding
     subscriptions, rights, warrants, options, calls, convertible securities,
     commitments of sale or rights related to or entitling any person to
     purchase or otherwise to acquire any shares of, or any security convertible
     into or exchangeable or exercisable for, the capital stock of, or other
     ownership interest in, the Company. The outstanding shares of capital stock
     of the Company's subsidiaries have been duly authorized and validly issued,
     are fully paid and non-assessable and are owned by the Company free and
     clear of any mortgage, pledge, lien, encumbrance, charge or adverse claim
     and are not the subject of any agreement or understanding with any person
     and were not issued in violation of any preemptive or similar rights; and
     there are no outstanding subscriptions, rights, warrants, options, calls,
     convertible securities, commitments of sale or instruments related to or
     entitling any person to purchase or otherwise acquire any shares of, or any
     security convertible into or exchangeable or exercisable for, the capital
     stock of, or other ownership interest in any of the subsidiaries.


                                       7

          (viii) The statements set forth in the Prospectus describing the
     Shares and this Agreement, insofar as they purport to describe the
     provisions of the laws and documents referred to therein, are accurate,
     complete and fair.

          (ix) Each of the Company and its subsidiaries is in possession of and
     is operating in compliance with all franchises, grants, authorizations,
     licenses, certificates, permits, easements, consents, orders and approvals
     ("Permits") from all state, federal, foreign and other regulatory
     authorities, and has satisfied the requirements imposed by regulatory
     bodies, administrative agencies or other governmental bodies, agencies or
     officials, that are required for the Company and its subsidiaries lawfully
     to own, lease and operate their properties and conduct their businesses as
     described in the Prospectus, and each of the Company and its subsidiaries
     is conducting its business in compliance with all of the laws, rules and
     regulations of each jurisdiction in which it conducts its business, in each
     case with such exceptions, individually or in the aggregate, as would not
     have a Material Adverse Effect; each of the Company and its subsidiaries
     has filed all notices, reports, documents or other information ("Notices")
     required to be filed under applicable laws, rules and regulations, in each
     case, with such exceptions, individually or in the aggregate, as would not
     have a Material Adverse Effect; and, except as otherwise specifically
     described in the Prospectus, neither the Company nor any of its
     subsidiaries has received any notification from any court or governmental
     body, authority or agency, relating to the revocation or modification of
     any such Permit or, to the effect that any additional authorization,
     approval, order, consent, license, certificate, permit, registration or
     qualification ("Approvals") from such regulatory authority is needed to be
     obtained by any of them, in any case where it could be reasonably expected
     that obtaining such Approvals or the failure to obtain such Approvals,
     individually or in the aggregate, would have a Material Adverse Effect.

          (x) The Company and its subsidiaries have filed all necessary federal,
     state and foreign income and franchise tax returns and paid all taxes shown
     as due thereon; all such tax returns are complete and correct in all
     material respects; all tax liabilities are adequately provided for on the
     books of the Company and its subsidiaries except to such extent as would
     not have a Material Adverse Effect; the Company and its subsidiaries have
     timely made all necessary payroll tax payments and are current and
     up-to-date; and the Company and its subsidiaries have no knowledge of any
     tax proceeding or action pending or threatened against the Company or its
     subsidiaries that, individually or in the aggregate, might have a Material
     Adverse Effect.

          (xi) Except as described in the Prospectus, the Company and its
     subsidiaries own or possess, or can acquire on reasonable terms, adequate
     patents, patent licenses, trademarks, service marks and trade names
     necessary to conduct the business now operated by them, and neither the
     Company nor any of its subsidiaries has received any

<PAGE>

     notice of infringement of or conflict with asserted rights of others with
     respect to any patents, patent licenses, trademarks, service marks or trade
     names that, individually or in the aggregate, if the subject of an
     unfavorable decision, ruling or finding, would have a Material Adverse
     Effect.

          (xii) The Company and its subsidiaries have legal, valid and
     defensible title to all of their interests in oil and gas properties and to
     all other real and personal property owned by them, in each case free and
     clear of all mortgages, pledges, security interests, claims, liens,
     encumbrances, restrictions and defects of any kind, except (1) such as are
     described in the Prospectus, (2) liens and encumbrances under operating
     agreements, unitization and pooling agreements, production sales contracts,
     farm-out agreements and other oil and gas exploration and production
     agreements, in each case that secure payment of amounts not yet due and
     payable for the performance of other inchoate obligations and are of a
     scope and nature customary in connection with similar drilling and
     producing operations, or (3) those that do not materially affect the value
     of such property and do not interfere with the use made and proposed to be
     made of such property; and any property held under lease or sublease by the
     Company or any of its subsidiaries is held under valid, subsisting and
     enforceable leases or subleases with such exceptions as are not material

     property by the Company and its subsidiaries or except such as are
     described in the Prospectus; and neither the Company nor any of its
     subsidiaries has any notice or knowledge of any material claim of any sort
     that has been, or may be, asserted by anyone adverse to the Company's or
     any of its subsidiaries rights as lessee or sublessee under any lease or
     sublease described above, or affecting or questioning the Company's or any
     of its subsidiaries' rights to the continued possession of the leased or
     subleased premises under any such lease or sublease in conflict with the
     terms thereof.

          (xiii) Except as described in the Prospectus or as would not have a
     Material Adverse Effect, there is no factual basis for any action, suit or
     other proceeding involving the Company or any of its subsidiaries or any of
     their material assets for any failure of the Company or any of its
     subsidiaries, or any predecessor thereof, to comply with any requirements
     of federal, state or local regulation relating to air, water, solid waste
     management, hazardous or toxic substances, or the protection of health or
     the environment. Except as described in the Prospectus or as would not have
     a Material Adverse Effect, none of the property owned or leased by the
     Company or any of its subsidiaries is, to the knowledge of the Company,
     contaminated with any waste or hazardous substances, and neither the
     Company nor any of its subsidiaries may be deemed an "owner or operator" of
     a "facility" or "vessel" that owns, possesses, transports, generates or
     disposes of a "hazardous substance" as those terms are defined in Section
     9601 of the Comprehensive Environmental Response, Compensation and
     Liability Act of 1980, 42 U.S.C. Section9601 ET SEQ.


                                       9

          (xiv) No labor disturbance exists with the employees of the Company or
     any of its subsidiaries or is imminent that, individually or in the
     aggregate, would have a Material Adverse Effect. None of the employees of
     the Company or any of its subsidiaries is represented by a union and, to
     the knowledge of the Company and its subsidiaries, no union organizing
     activities are taking place. Neither the Company nor any of its
     subsidiaries has violated any federal, state or local law or foreign law
     relating to discrimination in hiring, promotion or pay of employees, nor
     any applicable wage or hour laws, or the rules and regulations thereunder,
     or analogous foreign laws and regulations, that would reasonably be
     expected, individually or in the aggregate, to result in a Material Adverse
     Effect.

          (xv) The Company and its subsidiaries are in compliance in all
     material respects with all presently applicable provisions of the Employee
     Retirement Income Security Act of 1974, as amended, including the
     regulations and published interpretations thereunder ("ERISA"); no
     "reportable event" (as defined in ERISA) has occurred with respect to any
     "pension plan" (as defined in ERISA) for which the Company and its
     subsidiaries would have any liability; the Company and its subsidiaries
     have not incurred and do not expect to incur liability under (1) Title IV
     of ERISA with respect to termination of, or withdrawal from, any "pension
     plan" or (2) Sections 412 or 4971 of the Internal Revenue Code of 1986, as
     amended, including the regulations and published interpretations thereunder
     (the "Code"); and each "pension plan" for which the Company or any of its
     subsidiaries would have any liability that is intended to be qualified
     under Section 401(a) of the Code is so qualified in all material respects,
     and nothing has occurred, whether by action or by failure to act, that
     would cause the loss of such qualification.

          (xvi) The Company and its subsidiaries maintain insurance of the types
     and in the amounts generally deemed adequate for its business, including,
     but not limited to, directors' and officers' insurance, insurance covering
     real and personal property owned or leased by the Company and its
     subsidiaries against theft, damage, destruction, acts of vandalism and all
     other risks customarily insured against, all of which insurance is in full
     force and effect. Neither the Company nor any of its subsidiaries has been
     refused any insurance coverage sought or applied for, and the Company has
     no reason to believe that it and its subsidiaries will not be able to renew
     their existing insurance coverage as and when such coverage expires or to
     obtain similar coverage from similar insurers as may be necessary to
     continue its business at a cost that would not have a Material Adverse
     Effect.

          (xvii) Neither the Company nor any of its subsidiaries is, or with the
     giving of notice or lapse of time or both would be, in default or violation
     with respect to its articles of incorporation or bylaws. Neither the
     Company nor any of its subsidiaries is, or with


                                       10
<PAGE>

     the giving of notice or lapse of time or both would be, in default in the
     performance or observance of any material obligation, agreement, covenant
     or condition contained in any indenture, mortgage, deed of trust, loan
     agreement, lease or other agreement or instrument to which the Company or
     any of its subsidiaries is a party or by which the Company or any of its
     subsidiaries is bound or to which any of the properties or assets of the
     Company or any of its subsidiaries is subject, or in violation of any
     statutes, laws, ordinances or governmental rules or regulations or any
     orders or decrees to which it is subject, including, without limitation,
     Section 13 of the 1934 Act, which default or violation, individually or in
     the aggregate, would have a Material Adverse Effect. Neither the Company
     nor any of its subsidiaries has, at any time during the past five years,
     (1) made any unlawful contributions to any candidate for any political
     office, or failed fully to disclose any contribution in violation of law,
     or (2) made any payment to any state, federal or foreign government
     official, or other person charged with similar public or quasi-public duty
     (other than payment required or permitted by applicable law).

          (xviii) 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 is a party or of which any property of the Company or any of
     its subsidiaries is the subject that, if determined adversely to the
     Company or any of its subsidiaries, would individually or in the aggregate
     have a Material Adverse Effect or that would materially and adversely
     affect the consummation of the transactions contemplated hereby or that is
     required to be disclosed in the Prospectus; and to the Company's knowledge,
     no such proceedings are threatened or contemplated.

          (xix) The Company is not and, after giving effect to the offering and
     sale of the Shares, will not be a "holding company," or a "subsidiary
     company" of a "holding company," or an "affiliate" of a "holding company"
     or of a "subsidiary company," as such terms are defined in the Public
     Utility Holding Company Act of 1935, as amended (the "1935 Act").

          (xx) The Company is not and, after giving effect to the offering and
     sale of the Shares, will not be an "investment company" or an entity
     "controlled" by an "investment company," as such terms are defined in the
     Investment Company Act of 1940, as amended (the "1940 Act").

          (xxi) BDO Seidman, LLP, the accounting firm that has certified the
     financial statements filed with or incorporated by reference in and as a
     part of the Registration Statement, is an independent public accounting
     firm within the meaning of the 1933 Act and the 1933 Act Rules and
     Regulations. The Company and each of its subsidiaries maintains a system of
     internal accounting controls sufficient to provide reasonable assurance
     that: (1) transactions are executed in accordance with management's general
     or


                                       11
<PAGE>

     specific authorizations; (2) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain accountability for assets;
     (3) access to assets is permitted only in accordance with management's
     general or specific authorization; and (4) the recorded accounts for assets
     are compared with the existing assets at reasonable intervals and
     appropriate action is taken with respect thereto. The consolidated
     financial statements and schedules of the Company, including the notes
     thereto, filed with (or incorporated by reference) and as a part of the
     Registration Statement or Prospectus, are accurate in all material respects
     and present fairly the financial condition of the Company and its
     subsidiaries as of the respective dates thereof and the consolidated
     results of operations and changes in financial position and consolidated
     statements of cash flow for the respective periods covered thereby, all in
     conformity with generally accepted accounting principles applied on a
     consistent basis throughout the periods involved except as otherwise
     disclosed therein. All adjustments necessary for a fair presentation of
     results for such periods have been made. The selected financial data
     included or incorporated by reference in the Registration Statement and
     Prospectus present fairly the information shown therein and have been
     compiled on a basis consistent with that of the audited financial
     statements. Any operating or other statistical data included or
     incorporated by reference in the Registration Statement and Prospectus
     comply in all material respects with the 1933 Act and the 1933 Act Rules
     and Regulations and present fairly the information shown therein. The pro
     forma financial statements and the related notes thereto included or
     incorporated by reference in the Registration Statement and the Prospectus
     present fairly the information shown therein, have been prepared in
     accordance with the SEC's rules with respect to pro forma financial
     statements and have been properly compiled on the bases described therein,
     and the assumptions used in the preparation thereof are reasonable and the
     adjustments used therein are appropriate to give effect to the transactions
     and circumstances referred to therein

          (xxii) The historical financial statements (including the notes
     thereto) included or incorporated by reference in the Registration
     Statement and the Prospectus present fairly the revenues and direct
     operating expenses of the Acquisition Properties (as defined in the
     Prospectus), for the periods specified; except as otherwise stated in the
     Registration Statement or the Prospectus, said financial statements have
     been prepared in conformity with generally accepted accounting principles
     applied on a consistent basis and comply with the applicable accounting
     requirements of the 1933 Act, and all adjustments necessary for a fair
     presentation of the results for such periods have been made; the supporting
     schedules included or incorporated by reference in the Registration
     Statement and the Prospectus present fairly the information required to be
     stated therein.

          (xxiii) Except as disclosed in the Prospectus, no holder of any
     security of the Company has any right that has not been waived to require
     registration of shares of


                                       12
<PAGE>

     Common Stock or any other security of the Company because of the filing of
     the Registration Statement or the consummation of the transactions
     contemplated hereby and, except as disclosed in the Prospectus, no person
     has the right to require registration under the 1933 Act of any shares of
     Common Stock or other securities of the Company. No person has the right,
     contractual or otherwise, to cause the Company to permit such person to
     underwrite the sale of any of the Shares. Except for this Agreement, there
     are no contracts, agreements or understandings between the Company or any
     of its subsidiaries and any person that would give rise to a valid claim
     against the Company, its subsidiaries or any Underwriter for a brokerage
     commission, finder's fee or like payment in connection with the issuance,
     purchase and sale of the Shares.

          (xxiv) The Company has not distributed and, prior to the later to
     occur of (1) the Closing Date or the Option Closing Date, if any, and (2)
     completion of the distribution of the Shares, will not distribute any
     offering material in connection with the offering and sale of the Shares
     other than the Registration Statement, the Preliminary Prospectus or the
     Prospectus or any other materials permitted by the 1933 Act or the 1933 Act
     Rules and Regulations.

          (xxv) The Company has not taken and will not take, directly or
     indirectly, any action designed to or that might reasonably be expected to
     cause or result in stabilization or manipulation of the price of the
     Company's Common Stock, and the Company is not aware of any such action
     taken or to be taken by affiliates of the Company.

          (xxvi) Except for the shares of capital stock of each subsidiary owned
     by the Company and its subsidiaries, neither the Company nor any subsidiary
     owns any shares of capital stock or any other equity securities of any
     corporation or has any equity interest in any firm, partnership,
     association or other entity, except as described in the Prospectus.

          (xxvii) The petroleum engineers who have consented to being named as
     having reviewed certain reserve data included or incorporated by reference
     in the Prospectus are independent engineers with respect to the Company and
     its subsidiaries and the Acquisition Properties.

          (xxviii) The information underlying the estimates of oil and gas
     reserves as described in the Prospectus is complete and accurate in all
     material respects; other than production of the reserves in the ordinary
     course of business and intervening product price fluctuations described in
     the Prospectus, the Company is not aware of any facts or circumstances that
     would result in a material adverse change in the reserves or the present
     value of future net cash flows therefrom as described in the Prospectus.
     Estimates of such reserves and present values comply in all material
     respects with the applicable requirements of Regulation S-X and Industry
     Guide 2 under the 1933 Act.


                                       13
<PAGE>

          (xxix) No subsidiary of the Company is currently prohibited, directly
     or indirectly, from paying any dividends to the Company, from making any
     other distribution on such subsidiary's capital stock, from repaying to the
     Company any loans or advances to such subsidiary from the Company or from
     transferring any of such subsidiary's property of assets to the Company or
     any other subsidiary of the Company, except as described in or contemplated
     by the Prospectus (or, if the Prospectus is not in existence, the most
     recent Preliminary Prospectus).

     (b) Any certificate signed by any officer of the Company and delivered to
the Underwriters or to counsel for the Underwriters shall be deemed a
representation and warranty by the Company to each Underwriter as to the matters
covered thereby.

     5. ADDITIONAL COVENANTS. The Company covenants and agrees with the several
Underwriters that:

     (a) The Company will timely transmit copies of the Prospectus, and any
amendments or supplements thereto, to the SEC for filing pursuant to Rule 424(b)
of the 1933 Act Rules and Regulations.

     (b) The Company will deliver to each of the Underwriters, and to counsel

therein) as the Underwriters may reasonably request for the purposes
contemplated by the 1933 Act; the Company will promptly advise the Underwriters
of any request of the SEC for amendment of the Registration Statement or for
supplement to the Prospectus or for any additional information, and of the
issuance by the SEC or any state or other jurisdiction or other regulatory body
of any stop order under the 1933 Act or other order suspending the effectiveness
of the Registration Statement (as amended or supplemented) or preventing or
suspending the use of any Preliminary Prospectus or the Prospectus or suspending
the qualification or registration of the Shares for offering or sale in any
jurisdiction, and of the institution or threat of any proceedings therefor, of
which the Company shall have received notice or otherwise have knowledge prior
to the completion of the distribution of the Shares; and the Company will use
its best efforts to prevent the issuance of any such stop order or other order
and, if issued, to secure the prompt removal thereof.

<PAGE>

     (c) The Company will not file any amendment or supplement to the
Registration Statement, the Prospectus (or any other prospectus relating to the
Shares filed pursuant to Rule 424(b) of the 1933 Act Rules and Regulations that
differs from the Prospectus as filed pursuant to such Rule 424(b)) and will not
file any document under the 1934 Act before the termination of the offering of
the Shares by the Underwriters if the document would be deemed to be
incorporated by reference into the Registration Statement or the Prospectus, of
which the Underwriters shall not previously have been advised and furnished with
a copy or to which the Underwriters shall have reasonably objected or that is
not in compliance with the 1933 Act Rules and Regulations; and the Company will
promptly notify the Underwriters after it shall have received notice thereof of
the time when any amendment to the Registration Statement becomes effective or
when any supplement to the Prospectus has been filed.

     (d) During the period when a prospectus relating to any of the Shares is
required to be delivered under the 1933 Act by any Underwriter or dealer, the
Company will comply, at its own expense, with all requirements imposed by the
1933 Act and the 1933 Act Rules and Regulations, as now and hereafter amended,
and by the rules and regulations of the SEC thereunder, as from time to time in
force, so far as necessary to permit the continuance of sales of or dealing in
the Shares during such period in accordance with the provisions hereof and as
contemplated by the Prospectus.

     (e) If, during the period when a prospectus relating to any of the Shares
is required to be delivered under the 1933 Act by any Underwriter or dealer, (i)
any event relating to or affecting the Company or of which the Company shall be
advised in writing by the Underwriters shall occur as a result of which, in the
opinion of the Company or the Underwriters, the Prospectus as then amended or
supplemented would 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 or (ii) it
shall be necessary to amend or supplement the Registration Statement or the
Prospectus to comply with the 1933 Act, the 1933 Act Rules and Regulations, the
1934 Act or the 1934 Act Rules and Regulations, the Company will forthwith at
its expense prepare and file with the SEC, and furnish to the Underwriters a
reasonable number of copies of, such amendment or supplement or other filing
that will correct such statement or omission or effect such compliance.

     (f) During the period when a prospectus relating to any of the Shares is
required to be delivered under the 1933 Act by any Underwriter or dealer, the
Company will furnish such proper information as may be lawfully required and
otherwise cooperate in qualifying the Shares for offer and sale under the
securities or blue sky laws of such jurisdictions as the Underwriters may
reasonably designate and will file and make in each year such statements or
reports as are or may be reasonably required by the laws of such
jurisdictions; provided, however, that the Company shall not be required to
qualify as a foreign corporation or shall be required to qualify


                                       15

as a dealer in securities or to file a general consent to service of process
under the laws of any jurisdiction.

     (g) The Company will make generally available to its securityholders and to
holders of the Shares, as soon as practicable, a consolidated earnings statement

the provisions of Section 11(a) of the 1933 Act and Rule 158 of the 1933 Act
Rules and Regulations.

     (h) During any period in which a prospectus relating to any of the Shares
is required by law to be delivered under the 1933 Act by any Underwriter or
dealer, the Company will file promptly all documents required to be filed with
the SEC pursuant to Sections 13, 14 or 15(d) of the 1934 Act. The Company will
furnish to its security holders annual reports containing financial statements
audited by independent public accountants and quarterly reports containing
financial statements and financial information that may be unaudited. The
Company will, for a period of five years from the Closing Date, deliver to the
Underwriters at their principal executive offices a reasonable number of copies
of annual reports, quarterly reports, current reports and copies of all other
documents, reports and information furnished by the Company to its shareholders
or filed with any securities exchange or market pursuant to the requirements of
such exchange or market or with the SEC pursuant to the 1933 Act or the 1934
Act. The Company will deliver to the Underwriters similar reports with respect
to any significant subsidiaries, as that term is defined in the 1933 Act Rules
and Regulations, which are not consolidated in the Company's financial
statements, to the extent such reports are prepared in the ordinary course of
such subsidiary's business. Any report, document or other information required
to be furnished under this paragraph (h) shall be furnished as soon as
practicable after such report, document or information becomes available.

     (i) During the period beginning from the date of this Agreement and
continuing to and including 120 days after the date hereof, the Company will
not, without the prior written consent of A.G. Edwards & Sons, Inc., directly or
indirectly, offer for sale, sell or enter into any agreement to sell, or
otherwise dispose of, any shares of Common Stock, or any securities convertible
into or exchangeable for shares of Common Stock, except for the Shares and
except for issuances pursuant to the exercise of employee stock options
outstanding on the date hereof.

     (j) The Company will apply the proceeds from the sale of the Shares as set
forth in the description under "Use of Proceeds" in the Prospectus, which
description complies in all respects with the requirements of Item 504 of
Regulation S-K.

any documents incorporated by reference into the Registration Statement or the

covered by the financial statements appearing in the Registration Statement and
the Prospectus.

     (m) Prior to the Closing Date, the Company will not, without the prior
consent of A.G. Edwards & Sons, Inc., which consent shall not be unreasonably
withheld, issue any press releases or other public communications directly or
indirectly and will hold no press conferences, in each case relating to the

liabilities of the Company or any of its subsidiaries or the offering of the

non-routine press conferences, in each case relating to the financial condition,
results or operations, business, properties, assets or liabilities of the
Company or any of its subsidiaries or the offering of the Shares.

     (n) The Company will use its best efforts to obtain approval for, and
maintain the listing of the Shares on, the New York Stock Exchange.

     (o) The Company will cause its directors and officers to furnish to the
Underwriters, on or prior to the date of this Agreement, a letter or letters, in
form and substance satisfactory to counsel for the Underwriters, pursuant to
which each such person shall agree not to, directly or indirectly, offer for
sale, contract to sell, sell, distribute, grant any option, right or warrant to
purchase, pledge, hypothecate or otherwise dispose of any shares of Common
Stock, any securities convertible into, or exercisable or exchangeable for,
Common Stock or any other rights to acquire such shares, for a period of 120
days from the date hereof, without the prior written consent of A.G. Edwards &
Sons, Inc.

     (p) The Company and its subsidiaries will maintain and keep accurate books
and records reflecting their assets and maintain internal accounting controls
which provide reasonable assurance that (1) transactions are executed in
accordance with management's authorization, (2) transactions are recorded as
necessary to permit the preparation of the Company's consolidated financial
statements and to maintain accountability for the assets of the Company and its
subsidiaries, (3) access to the assets of the Company and its subsidiaries is
permitted only in accordance with management's authorization, and (4) the

Option Closing Date), respectively, in form and substance satisfactory to the
Underwriters, confirming that they are independent public accountants with
respect to the Company within the meaning of the 1933 Act and the published
Rules and Regulations, and stating to the effect set forth in Schedule II
hereto.

     (g) On the business day immediately preceding the date of this Agreement
and on the Closing Date (and, if applicable, the Option Closing Date), the
Underwriters shall have received from BDO Seidman, LLP, a letter or letters,
dated the date of this Agreement and the Closing Date (and, if applicable, the
Option Closing Date), respectively, confirming that they are independent public
accountants with respect to the Acquisition Properties within the meaning of the
1933 Act and the published Rules and Regulations, and otherwise in form and
substance satisfactory to the Underwriters.

     (h) Except as contemplated in the Prospectus, (i) neither the Company nor
any of its subsidiaries shall have sustained since the date of the latest
audited financial statements included or incorporated by reference in the
Prospectus any 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; and (ii) subsequent to
the respective dates as of which information is given in the Registration
Statement and the Prospectus, neither the Company nor any of its subsidiaries
shall have incurred any liability or obligation, direct or contingent, or
entered into any transactions, and there shall not have been any change in the
capital stock or short-term or long-term debt of the Company and its
subsidiaries or any change,


                                       19

or any development involving or that might reasonably be expected to involve a
prospective change in the condition (financial or other), net worth, business,
management, prospects, results of operations or cash flow of the Company or its
subsidiaries, the effect of which, in any such case described in clause (i) or
(ii), is in the judgment of the Underwriters so materially adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Shares being delivered on such Closing Date (and, if applicable, the
Option Closing Date) on the terms and in the manner contemplated in the
Prospectus.

     (i) There shall not have occurred any of the following: (i) a suspension or
material limitation in trading in securities generally on the New York Stock
Exchange or the American Stock Exchange or The Nasdaq National Market or the
establishing on such exchanges or market by the SEC or by such exchanges or
market of minimum or maximum prices that are not in force and effect on the date
hereof; (ii) a suspension or material limitation in trading in the Company's
securities on the New York Stock Exchange or the establishing on such exchange
by the SEC or by such exchange of minimum or maximum prices that are not in
force and effect on the date hereof; (iii) a general moratorium on commercial
banking activities declared by federal or New York or Colorado state
authorities; (iv) the outbreak or escalation of hostilities involving the United
States or the declaration by the United States of a national emergency or war,
which in the judgment of the Underwriters makes it impracticable or inadvisable
to proceed with the public offering or the delivery of the Shares in the manner
contemplated in the Prospectus; or (v) any calamity or crisis, change in
national, international or world affairs, act of God, change in the
international or domestic markets, or change in the existing financial,
political or economic conditions in the United States or elsewhere, which in the
judgment of the Underwriters makes it impracticable or inadvisable to proceed
with the public offering or the delivery of the Shares in the manner
contemplated in the Prospectus.

     (j) The Underwriters shall have received certificates, dated the Closing
Date (and, if applicable, the Option Closing Date) and signed by the President
and Chief Executive Officer and the Vice President Finance, Chief Financial
Officer and Treasurer of the Company, in their capacities as such, stating that:

          (i) the condition set forth in Section 6(a) has been fully satisfied;

          (ii) they have carefully examined the Registration Statement and the
     Prospectus as amended or supplemented and all documents incorporated by
     reference therein and nothing has come to their attention that would lead
     them to believe that either the Registration Statement (including any
     document filed under the 1934 Act and deemed incorporated by reference
     therein), as of the Effective Date and as of the date hereof, contained or
     contains an untrue statement of a material fact or omitted or omits to
     state a material fact required to be stated therein or necessary in order
     to make the statements therein not misleading, or the Prospectus or any
     amendment or supplement thereto


                                       20
<PAGE>

     (including any document filed under the 1934 Act and deemed incorporated by
     reference therein) as of its respective issue date and as of the Closing
     Date, or, if applicable, the Option Closing Date, contained or contains any
     untrue statement of a material fact or omitted or omits 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;

          (iii) since the most recent Effective Date, there has occurred no
     event required to be set forth in an amendment or supplement to the
     Registration Statement or the Prospectus that has not been so set forth and
     there has been no document required to be filed under the 1934 Act and the
     1934 Act Rules and Regulations that upon such filing would be deemed to be
     incorporated by reference into the Prospectus that has not been so filed;

          (iv) all representations and warranties made herein by the Company are
     true and correct at such Closing Date, with the same effect as if made on
     and as of such Closing Date, and all agreements herein to be performed or
     complied with by the Company on or prior to such Closing Date have been
     duly performed and complied with by the Company;

          (v) neither the Company nor any of its subsidiaries has sustained
     since the date of the latest audited financial statements included or
     incorporated by reference in the Prospectus any material loss or
     interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree;

          (vi) except as disclosed in the Prospectus, subsequent to the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, neither the Company nor any of its
     subsidiaries has incurred any liabilities or obligations, direct or
     contingent, other than in the ordinary course of business, or entered into
     any transactions not in the ordinary course of business, which in either
     case are material to the Company or such subsidiary; and there has not been
     any change in the capital stock or material increase in the short-term debt
     or long-term debt of the Company or any of its subsidiaries or any material
     adverse change or any development involving or that may reasonably be
     expected to involve a prospective material adverse change, in the condition
     (financial or other), net worth, business, management, prospects, results
     of operations or cash flow of the Company and its subsidiaries taken as a
     whole; and there has been no dividend or distribution of any kind, paid or
     made by the Company on any class of its capital stock;


                                       21
<PAGE>

          (vii) there has not been any change or decrease specified in paragraph
     6(a) of the letter or letters delivered to the Underwriters referred to in
     Section 6(f) above, except those changes and decreases that are disclosed
     therein; and

          (viii) covering such other matters as the Underwriters may reasonably
     request.

     (k) The Company shall not have failed, refused, or been unable, at or prior
to the Closing Date (and, if applicable, the Option Closing Date) to have
performed any agreement on its part to be performed or any of the conditions
herein contained and required to be performed or satisfied by the Company at or
prior to such Closing Date.

     (l) The Company shall have furnished to the Underwriters at the Closing
Date (and, if applicable, the Option Closing Date) such further information,
opinions, certificates, letters and documents as the Underwriters may have
reasonably requested.

     (m) The Shares shall have been approved for trading upon official notice of
issuance on the New York Stock Exchange.

     (n) The Underwriters shall have received duly and validly executed letter
agreements referred to in Section 5(o) hereof.

     (o) At the time of execution of this Agreement and on the Closing Date
(and, if applicable, the Option Closing Date), the Underwriters shall have
received a signed letter, dated the date of this Agreement and the Closing Date
(and, if applicable, the Option Closing Date), respectively, in form and
substance satisfactory to the Underwriters from each of Netherland, Sewell &
Associates, Inc. and Resource Services International, Inc.

     All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are satisfactory in form and
substance to the Underwriters and to Vinson & Elkins L.L.P., counsel for the
several Underwriters. The Company will furnish the Underwriters with such signed
and conformed copies of such opinions, certificates, letters and documents as
they may request.

     If any of the conditions specified above in this Section 6 shall not have
been satisfied at or prior to the Closing Date (and, if applicable, the Option
Closing Date) or waived by the Underwriters in writing, this Agreement may be
terminated by the Underwriters on notice to the Company.

     7. INDEMNIFICATION AND CONTRIBUTION. (a) The Company will indemnify and
hold harmless each Underwriter for and against any losses, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the 1933 Act or otherwise, insofar as such


                                       22
<PAGE>

losses, damages or liabilities (or actions or claims in respect thereof) arise
out of or are based upon (i) an untrue statement or alleged untrue statement of
a material fact contained in any Preliminary Prospectus, the Registration
Statement, the Prospectus or any other prospectus relating to the Shares, or any
amendment or supplement thereto, or in any blue sky application or other
document executed by the Company or based on any information furnished in
writing by the Company, filed in any state or other jurisdiction in order to
qualify any or all of the Shares under the securities laws thereof (the "Blue
Sky Application"), or (ii) 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 will reimburse each Underwriter for any legal or
other expenses incurred by such Underwriter in connection with investigating,
preparing, pursuing or defending against or appearing as a third party witness
in connection with any such loss, damage, liability or action or claim,
including, without limitation, any investigation or proceeding by any
governmental agency or body, commenced or threatened, including the reasonable
fees and expenses of counsel to the indemnified party, as such expenses are
incurred (including such losses, damages, liabilities or expenses to the extent
of the aggregate amount paid in settlement of any such action or claim, provided
that (subject to Section 7(c) hereof) any such settlement is effected with the
written consent of the Company); provided, however, that the Company shall not
be liable in any such case to the extent, but only to the extent, that any such
loss, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement, the Prospectus or any other prospectus
relating to the Shares, or any such amendment or supplement, in reliance upon
and in conformity with written information relating to the Underwriter furnished
to the Company by any Underwriter, expressly for use in the preparation thereof
(as provided in Section 13 hereof); and provided, further, that the Company will
not be liable to any Underwriter (or any person who controls such Underwriter or
any officer, director, employee, agent or other representative of such
Underwriter) with respect to any such untrue statement or omission made in any
Preliminary Prospectus that is corrected in the Prospectus (or any supplement
thereto) if the person asserting any such loss, claim, damage or liability
purchased the Shares from such Underwriter but was not sent or given a copy of
the Prospectus (as supplemented), other than the documents incorporated by
reference therein, at or prior to the written confirmation of the sale of such
Shares to such person in any case where such delivery of the Prospectus (as
supplemented) is required by the 1933 Act, unless the failure to deliver the
Prospectus (as supplemented) was a result of noncompliance by the Company with
Section 5(e) of this Agreement.

     (b) Each Underwriter, severally and not jointly, will indemnify and hold
harmless the Company for and against any losses, damages or liabilities to which
the Company may become subject, under the 1933 Act or otherwise, insofar as such
losses, damages or liabilities (or actions or claims in respect thereof) arise
out of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement, the Prospectus or any other prospectus relating to the Shares, or any
amendment or supplement


                                       23
<PAGE>

thereto, or any Blue Sky Application, or arise out of 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, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement, the Prospectus or any other
prospectus relating to the Shares, or any such amendment or supplement, or any
Blue Sky Application, in reliance upon and in conformity with written
information relating to the Underwriter furnished to the Company by any
Underwriter, expressly for use in the preparation thereof (as provided in
Section 13 hereof), and will reimburse the Company for any legal or other
expenses incurred by the Company in connection with investigating or defending
any such action or claim as such expenses are incurred (including such losses,
damages, liabilities or expenses to the extent of the aggregate amount paid in
settlement of any such action or claim, provided that (subject to Section 7(c)
hereof) any such settlement is effected with the written consent of the
Underwriters).

     (c) Promptly after receipt by an indemnified party under Section 7(a) or
7(b) hereof of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against an indemnifying party
under Section 7(a) or 7(b) hereof, notify each such indemnifying party in
writing of the commencement thereof, but the failure so to notify such
indemnifying party shall not relieve such indemnifying party from any liability
except to the extent that it has been prejudiced in any material respect by such
failure or from any liability that it may have to any such indemnified party
otherwise than under Section 7(a) or 7(b) hereof. In case any such action shall
be brought against any such indemnified party and it shall notify each
indemnifying party of the commencement thereof, each such indemnifying party
shall be entitled to participate therein and, to the extent that it shall wish,
jointly with any other indemnifying party under Section 7(a) or 7(b) hereof
similarly notified, to assume the defense thereof, with counsel satisfactory to
such indemnified party (who shall not, except with the consent of such
indemnified party, be counsel to such indemnifying party), and, after notice
from such indemnifying party to such indemnified party of its election so to
assume the defense thereof, such indemnifying party shall not be liable to such
indemnified party under Section 7(a) or 7(b) hereof for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. The indemnified party shall have the right to employ its
own counsel in any such action, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the employment of counsel
by such indemnified party at the expense of the indemnifying party has been
authorized by the indemnifying party, (ii) the indemnified party shall have been
advised by such counsel that there may be a conflict of interest between the
indemnifying party and the indemnified party in the conduct of the defense, or
certain aspects of the defense, of such action (in which case the indemnifying
party shall not have the right to direct the defense of such action with respect
to those matters or aspects of the defense on which a conflict exists or may
exist on behalf of the indemnified party) or (iii) the indemnifying party shall
not in fact have employed counsel reasonably satisfactory to such


                                       24
<PAGE>

indemnified party to assume the defense of such action, in any of which events
such fees and expenses to the extent applicable shall be borne, and shall be
paid as incurred, by the indemnifying party. If at any time such indemnified
party shall have requested such indemnifying party under Section 7(a) or 7(b)
hereof to reimburse such indemnified party for fees and expenses of counsel,
such indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 7(a) or 7(b) hereof effected without its written
consent if (i) such settlement is entered into more than 45 days after receipt
by such indemnifying party of such request for reimbursement, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request for reimbursement prior to the date of such
settlement. No such indemnifying party shall, without the written consent of
such indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not such indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (A)
includes an unconditional release of such indemnified party from all liability
arising out of such action or claim and (B) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any such indemnified party. In no event shall such indemnifying parties be
liable for the fees and expenses of more than one counsel, including any local
counsel, for all such indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

     (d) If the indemnification provided for in this Section 7 is unavailable to
or insufficient to indemnify or hold harmless an indemnified party under Section
7(a) or 7(b) hereof in respect of any losses, damages or liabilities (or actions
or claims in respect thereof) referred to therein, then each indemnifying party
under Section 7(a) or 7(b) hereof shall contribute to the amount paid or payable
by such indemnified party as a result of such losses, damages or liabilities (or
actions or claims in respect thereof) in such proportion as is appropriate to
reflect the relative benefits received by the Company, on the one hand, and the
Underwriters, on the other hand, from the offering of the Shares. If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law or if the indemnified party failed to give the notice required
under Section 7(c) hereof and such indemnifying party was prejudiced in a
material respect by such failure, then each such indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault, as applicable, of the Company, on the one hand, and the
Underwriters, on the other hand, in connection with the statements or omissions
that resulted in such losses, damages or liabilities (or actions or claims in
respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by, as applicable, the Company, on the one hand, and
the Underwriters, on the other hand, shall be deemed to be in the same
proportion as the total net proceeds from such offering


                                       25
<PAGE>

(before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters. The
relative fault, as applicable, of the Company, on the one hand, and the
Underwriters, on the other hand, shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company, on the one hand, or the Underwriters, on
the other hand, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contribution pursuant to this Section 7(d) were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to above in this Section 7(d). The amount paid
or payable by such an indemnified party as a result of the losses, damages or
liabilities (or actions or claims in respect thereof) referred to above in this
Section 7(d) shall be deemed to include any legal or other expenses incurred by
such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 7(d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Shares underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such 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 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The obligations of the Underwriters in this
Section 7(d) to contribute are several in proportion to their respective
underwriting obligations with respect to the Shares and not joint.

     (e) The obligations of the Company and the Underwriters under this Section
7 shall be in addition to any liability that they may otherwise have and shall
extend, upon the same terms and conditions, to each officer, director, employee,
agent or other representative and to each person, if any, who controls the
Company or any Underwriter within the meaning of the 1933 Act.

     (f) The parties to this Agreement hereby acknowledge that they are
sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof, including, without limitation, the
provisions of this Section 7, and are fully informed regarding such provisions.
They further acknowledge that the provisions of this Section 7 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, and any
supplement or amendment thereof, as required by the 1933 Act.

     8. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. The respective
representations, warranties, agreements and statements of the Company and the
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain operative and in full
force and effect regardless of any investigation (or any statement as to the
results thereof) made by or on behalf of any Underwriter or any controlling
person of any Underwriter, or the Company or any of its officers, directors or
any controlling persons, and shall survive delivery of and payment for the
Shares hereunder.

     9. SUBSTITUTION OF UNDERWRITERS. (a) If any Underwriter shall default in
its obligation to purchase the Shares that it has agreed to purchase hereunder,
the Underwriters may in their discretion arrange for one or more of the
Underwriters or another party or other parties to purchase such Shares on the
terms contained herein. If within thirty-six hours after such default by any
Underwriter the Underwriters do not arrange for the purchase of such Shares,
then the Company shall be entitled to a further period of thirty-six hours
within which to procure another party or parties reasonably satisfactory to the
Underwriters to purchase such Shares on such terms. In the event that, within
the respective prescribed periods, the Underwriters notify the Company that they
have so arranged for the purchase of such Shares, or the Company notifies the
Underwriters that it has so arranged for the purchase of such Shares, the
Underwriters or the Company shall have the right to postpone the Closing Date
for a period of not more than seven days, in order to effect whatever changes
may thereby be made necessary in the Registration Statement or the Prospectus,
or in any other documents or arrangements, and the Company agrees to file
promptly any amendments to the Registration Statement or the Prospectus that in
the opinion of the Underwriters may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any persons substituted
under this Section 9 with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

     (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters made by the Underwriters and
the Company as provided in subsection (a) above, the aggregate number of Shares
that remains unpurchased does not exceed one-eleventh of the total Shares to be
sold on the Closing Date, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the Shares which such Underwriter agreed
to purchase hereunder and, in addition, to require each non-defaulting
Underwriter to purchase its pro rata share (based on the number of Shares which
such Underwriter agreed to purchase hereunder) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

     (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters made by the Underwriters and
the Company as provided in subsection (a) above, the number of Shares which
remains unpurchased exceeds one-eleventh of the total Shares to be sold on the
Closing Date, or if the Company shall not exercise the right


                                       27
<PAGE>

described in subsection (b) above to require the non-defaulting Underwriters to
purchase Shares of the defaulting Underwriter or Underwriters, then this
Agreement (or, with respect to the Option Closing Date, the obligations of the
Underwriters to purchase and of the Company to sell the Option Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company except for the expenses to be borne by the Company
and the Underwriters as provided in Section 11 hereof and the indemnity and
contribution agreements in Section 7 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     10. EFFECTIVE DATE AND TERMINATION. (a) This Agreement may be terminated by
the Underwriters at any time at or prior to the Closing Date by notice to the
Company if any condition specified in Section 6 hereof shall not have been
satisfied on or prior to the Closing Date. Any such termination shall be without
liability of any party to any other party except as provided in Sections 7 and
11 hereof.

     (b) This Agreement also may be terminated by the Underwriters, by notice to
the Company, as to any obligation of the Underwriters to purchase the Option
Shares, if any condition specified in Section 6 hereof shall not have been
satisfied at or prior to the Option Closing Date or as provided in Section 9 of
this Agreement.

     (c) If the Underwriters terminate this Agreement as provided in Sections
10(a) or 10(b), the Underwriters shall notify the Company by telephone or
telegram, confirmed by letter.

     11. COSTS AND EXPENSES. The Company, whether or not the transactions
contemplated hereby are consummated or this Agreement is prevented from becoming
effective under Section 10 hereof or is terminated, will bear and pay the costs
and expenses incident to the registration of the Shares and public offering
thereof, including, without limitation, (a) all expenses (including stock
transfer taxes) incurred in connection with the delivery to the several
Underwriters of the Shares, the filing fees of the SEC, the fees and expenses of
the Company's counsel and accountants and the fees and expenses of counsel for
the Company, (b) the preparation, printing, filing, delivery and shipping of the
Registration Statement, each Preliminary Prospectus, the Prospectus and any
amendments or supplements thereto (except as otherwise expressly provided in
Section 5(d) hereof) and the printing, delivery and shipping of this Agreement
and other underwriting documents, including the Agreement Among Underwriters,
the Selected Dealer Agreement, Underwriters' Questionnaires and Powers of
Attorney, and any instruments or documents related to any of the foregoing, (c)
the furnishing of copies of such documents (except as otherwise expressly
provided in Section 5(d) hereof) to the Underwriters, (d) the registration or
qualification of the Shares for offering and sale under the securities laws of
the various states and other jurisdictions, including the fees and disbursements
of counsel to the Underwriters relating to such registration or qualification,
(e) the filing fees of the NASD (if any) and fees and disbursements of counsel
to the Underwriters relating to any


                                       28
<PAGE>

review of the offering by the NASD, (f) all printing and engraving costs related
to preparation of the certificates for the Shares, including transfer agent and
registrar fees, (g) all fees and expenses relating to the authorization of the
Shares for trading on the New York Stock Exchange, (h) all travel expenses,
including air fare and accommodation expenses, of representatives of the Company
in connection with the offering of the Shares (other than shall have been
specifically approved by A.G. Edwards & Sons, Inc. to be paid for by the
Underwriters), and (i) all of the other costs and expenses incident to the
performance by the Company of the registration and offering of the Shares;
provided, that the Underwriters will bear and pay the fees and expenses of the
Underwriters' counsel (except as provided in this Section 11), the Underwriters'
out-of-pocket expenses, and any advertising costs and expenses incurred by the
Underwriters incident to the public offering of the Shares.

<PAGE>

                                   SCHEDULE II

     Pursuant to Section 6(f) of the Underwriting Agreement, BDO Seidman, LLP
shall furnish letters to the Underwriters to the effect that:

         (i) They are independent certified public accountants with respect to
the Company and its subsidiaries within the meaning of the 1933 Act and the
applicable Rules and Regulations thereunder.

         (ii) In their opinion, the financial statements and any supplementary
financial information and schedules audited (and, if applicable, prospective
financial statements and/or pro forma financial information examined) by them
and included or incorporated by reference in the Prospectus or the Registration
Statement comply as to form in all material respects with the applicable
accounting requirements of the 1933 Act and the applicable Rules and Regulations
with respect to registration statements on Form S-3; and, if applicable, they
have made a review in accordance with standards established by the American
Institute of Certified Public Accountants of the unaudited consolidated interim
financial statements, selected financial data, pro forma financial information,
prospective financial statements and/or condensed financial statements derived
from audited financial statements of the Company for the periods specified in
such letter, as indicated in their reports thereon, copies of which have been
furnished to the Underwriters.

         (iii) On the basis of limited procedures, not constituting an audit in
accordance with generally accepted auditing standards, consisting of a reading
of the unaudited financial statements and other information referred to below,
performing the procedures specified by the AICPA for a review of interim
financial information as discussed in SAS No. 71, Interim Financial Information,
on the latest available interim financial statements of the Company and its
subsidiaries, inspection of the minute books of the Company and its subsidiaries
since the date of the latest audited financial statements included in the
Prospectus, inquiries of officials of the Company and its subsidiaries
responsible for financial and accounting matters and such other inquiries and
procedures as may be specified in such letter, nothing came to their attention
that caused them to believe that:

               (A) any material modifications should be made to the unaudited
          statements of consolidated income, statements of consolidated
          financial position and statements of consolidated cash flows included
          or incorporated by reference in the Prospectus for them to be in
          conformity with generally accepted accounting principles, or the
          unaudited statements of consolidated income, statements of
          consolidated financial position and statements of consolidated cash
          flows included in the Prospectus do not comply as to form in all
          material respects with the


                                 Schedule II-1
<PAGE>

          applicable accounting requirements of the 1933 Act and the related
          published Rules and Regulations thereunder.

               (B) any other unaudited income statement data and balance sheet
          items included or incorporated by reference in the Prospectus do not
          agree with the corresponding items in the unaudited consolidated
          financial statements from which such data and items were derived, and
          any such unaudited data and items were not determined on a basis
          substantially consistent with the basis for the corresponding amounts
          in the audited consolidated financial statements included or
          incorporated by reference in the Prospectus.

               (C) the unaudited financial statements which were not included or
          incorporated by reference in the Prospectus but from which were
          derived any unaudited condensed financial statements referred to in
          Clause (A) and any unaudited income statement data and balance sheet
          items included in the Prospectus and referred to in Clause (B) were
          not determined on a basis substantially consistent with the basis for
          the audited consolidated financial statements included or incorporated
          by reference in the Prospectus.

               (D) any unaudited pro forma consolidated condensed financial
          statements included or incorporated by reference in the Prospectus do
          not comply as to form in all material respects with the applicable
          accounting requirements of the 1933 Act and the published rules and
          regulations thereunder or the pro forma adjustments have not been
          properly applied to the historical amounts in the compilation of those
          statements.

               (E) as of a specified date not more than five days prior to the
          date of such letter, there have been any changes in the consolidated
          capital stock or any increase in the consolidated long-term debt of
          the Company and its subsidiaries, or any decreases in consolidated
          working capital, net current assets or net assets, or any changes in
          any other items specified by the Underwriters, in each case as
          compared with amounts shown in the latest balance sheet included or
          incorporated by reference in the Prospectus, except in each case for
          changes, increases or decreases which the Prospectus discloses have
          occurred or may occur or that are described in such letter.

               (F) for the period from the date of the latest financial
          statements included or incorporated by reference in the Prospectus to
          the specified date referred to in Clause (E) there were any decreases
          in consolidated net revenues or operating profit or the total or per
          share amounts of consolidated net income or any changes in any other
          items specified by the Underwriters, in each case as


                                 Schedule II-2
<PAGE>

          compared with the comparable period of the preceding year and with any
          other period of corresponding length specified by the Underwriters,
          except in each case for changes, decreases or increases which the
          Prospectus discloses have occurred or may occur or which are described
          in such letter.

         (iv) In addition to the audit referred to in their report(s) included
or incorporated by reference in the Prospectus and the limited procedures,
inspection of minute books, inquiries and other procedures referred to in
paragraph (iii) above, they have carried out certain specified procedures, not
constituting an audit in accordance with generally accepted auditing standards,
with respect to certain amounts, percentages and financial information specified
by the Underwriters, which are derived from the general accounting records of
the Company and its subsidiaries for the periods covered by their reports and
any interim or other periods since the latest period covered by their reports,
which appear or are incorporated by reference in the Prospectus, or in Part II
of, or in exhibits and schedules to, the Registration Statement specified by the
Underwriters, and have compared certain of such amounts, percentages and
financial information with the accounting records of the Company and its
subsidiaries and have found them to be in agreement.


                                 Schedule II-3

<PAGE>

                                     ANNEX A

                OPINION OF WOMBLE CARLYLE SANDRIDGE & RICE, PLLC

          1. The Company and each of its "significant subsidiaries," as such
     term is defined in Rule 1-02(w) of Regulation S-X under the 1933 Act (each,
     a "Subsidiary" and, collectively, the "Subsidiaries"), have been duly
     incorporated and are validly existing as corporations in good standing
     under the laws of their respective jurisdictions of incorporation and
     are duly qualified to transact business as foreign corporations and are in
     good standing under the laws of all other jurisdictions where the ownership
     or leasing of their respective properties or the conduct of their
     respective businesses requires such qualification, except where the failure
     to be so qualified does not amount to a material liability or disability
     to the Company and the Subsidiaries, taken as a whole.

          2. The Company and each of the Subsidiaries have corporate power to
     own or lease their respective properties and conduct their respective
     businesses as described in the Registration Statement and the Prospectus,
     and the Company has corporate power to enter into this Agreement and to
     carry out all the terms and provisions hereof to be carried out by it.

          3. The issued shares of capital stock of each of the Subsidiaries have
     been duly authorized and validly issued, are fully paid and non-assessable
     and, except for directors' qualifying shares and as otherwise set forth in
     the Prospectus, are owned beneficially by the Company free and clear of any
     perfected security interests, or to such counsel's knowledge, any other
     security interests, liens, encumbrances, equities or claims, and are not
     the subject of any agreement or understanding with any person, and were not
     issued in violation of any preemptive or similar rights; and, to the
     knowledge of such counsel, except as disclosed in the Prospectus, there are
     no outstanding subscriptions, rights, warrants, options, calls, convertible
     securities, commitments of sale, or instruments related to or entitling any
     person to purchase or otherwise acquire any shares of, or any security
     convertible into or exercisable or exchangeable for any such shares of,
     capital stock or other ownership interest of any of the Subsidiaries.

          4. The Company has an authorized, issued and outstanding
     capitalization as set forth in the Prospectus; all of the issued shares of
     capital stock of the Company have been duly authorized and validly issued
     and are fully paid and non-assessable, during the past three (3) years have
     been issued in compliance with all applicable federal and state securities
     laws and were not issued in violation of or subject to any preemptive
     rights or other rights to subscribe for or purchase securities; the Shares
     have been duly authorized by all necessary corporate action of the Company
     and, when issued and delivered to and


                                    Annex A-1
<PAGE>

     paid for by the Underwriters pursuant to this Agreement, will be validly
     issued, fully paid and non-assessable; and no holders of outstanding shares
     of capital stock of the Company are entitled as such to any preemptive or
     other rights to subscribe for any of the Shares.

          5. The Shares are duly authorized for trading, subject to official
     notice of issuance and evidence of satisfactory distribution, on the New
     York Stock Exchange. The issuance of the Shares is not subject to
     preemptive or other similar rights, or any restriction upon the voting or
     transfer thereof pursuant to applicable law or the articles of
     incorporation, bylaws or governing documents of the Company; and, to such
     counsel's knowledge, except as described in the Prospectus, there are no
     outstanding subscriptions, rights, warrants, options, calls, convertible
     securities, commitments of sale or rights related to or entitling any
     person to purchase or otherwise acquire any shares of, or any security
     convertible into or exercisable or exchangeable for, the capital stock of,
     or other ownership interest in, the Company.

          6. The Common Stock conforms to the description thereof set forth in
     the Prospectus under the heading "Description of Common Stock" and, insofar
     as such description constitutes a summary of the legal matters, documents
     or proceedings referred to therein, it provides a fair summary of such
     legal matters, documents and proceedings.

          7. The execution and delivery of this Agreement have been duly
     authorized by all necessary corporate action of the Company, and this
     Agreement has been duly executed and delivered by the Company.

          8. To the knowledge of such counsel after due inquiry, no legal or
     governmental proceedings are pending to which the Company or any of the
     Subsidiaries is a party or to which the property of the Company or any of
     the Subsidiaries is subject that are required to be described in the
     Registration Statement or the Prospectus and are not described therein, and
     to such counsel's knowledge, no such proceedings have been threatened
     against the Company or any of the Subsidiaries or with respect to any of
     their respective properties; and, to such counsel's knowledge after due
     inquiry, no contract or other document is required to be filed as an
     exhibit to the Registration Statement that is not filed as required.

          9. The issuance, offering and sale of the Shares to the Underwriters
     by the Company pursuant to this Agreement, the compliance by the Company
     with the other provisions of this Agreement and the consummation of the
     other transactions provided for herein do not (A) require the consent,
     approval, authorization, registration or qualification of or with any
     governmental authority, except such as have been obtained and such as may
     be required under state securities or blue sky laws, or (B) violate any of
     the terms and provisions of, or constitute a default under, any instrument
     to which the

                                    Annex A-2
<PAGE>

     Company or any of the Subsidiaries is a party and filed as an exhibit to
     (i) the Registration Statement, (ii) the most recent Annual Report on Form
     10-K incorporated by reference therein or (iii) any other report filed by
     the Company with the SEC under Section 13(a) of the 1934 Act after the date
     of such Annual Report on Form 10-K, except for such violations and defaults
     that would not have a material adverse effect on the business, financial
     condition or results of operations of the Company and the Subsidiaries,
     taken as a whole, or violate the articles of incorporation or bylaws of the
     Company or the governing documents of any of the Subsidiaries or, to such
     counsel's knowledge, any applicable law or any order of any court or other
     governmental authority or any arbitrator known to such counsel and
     applicable to the Company or any of the Subsidiaries.

          10. The Registration Statement is effective under the 1933 Act; any
     required filing of the Prospectus pursuant to Rule 424(b) has been made in
     the manner and within the time period required by Rule 424(b); and, to the
     knowledge of such counsel after due inquiry, no stop order suspending the
     effectiveness of the Registration Statement or any post-effective amendment
     thereto and no order directed at any document incorporated by reference in
     the Registration Statement, the Prospectus or any amendment or supplement
     thereto has been issued, and, to such counsel's knowledge after due
     inquiry, no proceedings for that purpose have been instituted or threatened
     or are contemplated by the SEC.

          11. The Registration Statement originally filed with respect to the
     Shares and each amendment thereto and the Prospectus (in each case,
     including the documents incorporated by reference therein, but not
     including the financial statements and other financial or statistical
     information contained or incorporated by reference therein and any
     information furnished by the Underwriters, as to which such counsel need
     express no opinion) comply as to form in all material respects with the
     applicable requirements of the 1933 Act, the Exchange Act and the
     respective rules and regulations of the SEC thereunder.

          12. The Company is not and, after giving effect to the offering and
     sale of the Shares, will not be an "investment company" or an entity
     "controlled" by an "investment company," as such terms are defined in the
     1940 Act.

          13. To the knowledge of such counsel after due inquiry and except as
     disclosed in the Prospectus, no holder of any security of the Company has
     any right, which has not been waived, to require registration of shares of
     Common Stock or any other security of the Company because of the filing of
     the Registration Statement or the consummation of the transactions
     contemplated hereby.


                                    Annex A-3
<PAGE>

     Such counsel shall confirm that during the preparation of the Registration
Statement and the Prospectus, such counsel participated in conferences with the
Underwriters and their counsel and with officers and representatives of the
Company and its independent accountants, at which conferences the contents of
the Registration Statement and the Prospectus (including all documents filed
under the 1934 Act and deemed incorporated by reference therein) were discussed,
reviewed and revised. On the basis of the information that was developed in the
course thereof, considered in light of such counsel's understanding of
applicable law and the experience gained by such counsel through their practice
thereunder, without such counsel assuming responsibility for the accuracy and
completeness of such statements except to the extent expressly provided above,
such counsel shall confirm that nothing came to their attention that would lead
them to believe that either the Registration Statement (including any document
filed under the 1934 Act and deemed incorporated by reference therein), as of
the Effective Date, contained or contains an untrue statement of a material fact
or omitted or omits to state a material fact required to be stated therein or
necessary in order to make the statements therein not misleading, or the
Prospectus or any amendment or supplement thereto (including any document filed
under the 1934 Act and deemed incorporated by reference therein) as of its
respective issue date and as of the Closing Date, or, if applicable, the Option
Closing Date, contained or contains any untrue statement of a material fact or
omitted or omits 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 (other than the financial statements or other financial
data as to which such counsel need express no opinion).

     In rendering the foregoing opinion, such counsel may rely, (1) as to the
matters set forth in paragraphs 1 through 5 (except the first sentence of
paragraph 5) and paragraph 7 solely on the opinion of Berenbaum, Weinshienk &
Eason, P.C., (2) as to matters involving the application of the laws of Colorado
solely on the opinion of Berenbaum, Weinshienk & Eason, P.C., or such other
counsel satisfactory to them and Vinson & Elkins L.L.P., and (3) as to all
matters of fact, upon certificates and written statements of the executive
officers of, and accountants for, the Company, provided, in either case, that
such counsel shall state in their opinion that they and the Underwriters are
justified in relying thereon.
