Ladies and Gentlemen:

          Midcoast Energy Resources, Inc., a Nevada corporation (the "Company"),
and the persons listed in Schedule B hereto (the "Selling Shareholders"),
confirm their respective agreements with Merrill Lynch & Co., Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), CIBC World Markets Corp.,
Prudential Securities Incorporated  and each of the other Underwriters named in
Schedule A hereto (collectively, the "Underwriters", which term shall also
include any underwriter substituted as hereinafter provided in Section 10
hereof), for whom Merrill Lynch, CIBC World Markets Corp., and Prudential
Securities Incorporated are acting as representatives (in such capacity, the
"Representatives"), with respect to (i) the sale by the Company and the Selling
Shareholders, acting severally and not jointly, and the purchase by the
Underwriters, acting severally and not jointly, of the respective numbers of
shares of Common Stock, par value $.01 per share, of the Company ("Common
Stock") set forth in Schedules A and B hereto and (ii) the grant by the Company
to the Underwriters, acting severally and not jointly, of the option described
in Section 2(b) hereof to purchase all or any part of 519,000 additional shares
of Common Stock to cover over-allotments, if any.  The aforesaid 3,460,000
shares of Common Stock (the "Initial Securities") to be purchased by the
Underwriters and all or any part of the 519,000 shares of Common Stock subject
to the option described in Section 2(b) hereof (the "Option Securities") are
hereinafter called, collectively, the "Securities."

     The Company and the Selling Shareholders understand that the Underwriters
propose to make a public offering of the Securities as soon as the
Representatives deem advisable after this Agreement has been executed and
delivered.

                                       4
<PAGE>

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-70371) for the
registration of the Securities under the Securities Act of 1933, as amended (the
"1933 Act"), and the offering thereof from time to time in accordance with Rule
415 of the rules and regulations of the Commission under the 1933 Act (the "1933
Act Regulations").  Such registration statement has been declared effective by
the Commission, the Company has filed such post-effective amendments thereto as
may be required, and each such post-effective amendment has been declared
effective by the Commission.  Such registration statement (as so amended, if
applicable), including the information, if any, deemed to be a part thereof
pursuant to Rule 430A(b) of the 1933 Act Regulations (the"Rule 430A
Information") are referred to herein as the "Registration Statement"; and the
final prospectus and the final prospectus supplement relating to the offering of
the Securities, in the forms first furnished to the Underwriters by the Company
for use in connection with the offering of the Securities, are collectively
referred to herein as the "Prospectus"; provided, however, that all references
to the "Registration Statement" and the "Prospectus" shall also be deemed to
include all documents incorporated therein by reference pursuant to the
Securities Exchange Act of 1934, as amended (the "1934 Act").  A "preliminary
prospectus" shall be deemed to refer to (i) any prospectus used before the
Registration Statement became effective and (ii) any prospectus that omitted, as
applicable, the Rule 430A Information or other information to be included upon
pricing in a form of prospectus filed with the Commission pursuant to Rule
424(b) of the 1933 Act Regulations and was used after such effectiveness and
prior to the initial delivery of the Prospectus to the Underwriters by the
Company.  For purposes of this Agreement, all references to the Registration
Statement, Prospectus or preliminary prospectus or to any amendment or
supplement to any of the foregoing shall be deemed to include any copy filed
with the Commission pursuant to its Electronic Data Gathering, Analysis and
Retrieval system ("EDGAR").

     All references in this Agreement to financial statements and schedules and
other information which are "contained," "included" or "stated" (or other
references of like import) in the Registration Statement, Prospectus or
preliminary prospectus shall be deemed to mean and include all such financial
statements and schedules and other information which are incorporated by
reference in the Registration Statement, Prospectus or preliminary prospectus,
as the case may be; and all references in this Agreement to amendments or
supplements to the Registration Statement, Prospectus or preliminary prospectus
shall be deemed to include the filing of any document under the 1934 Act which
is incorporated by reference in the Registration Statement, prospectus or
preliminary prospectus, as the case may be.

     SECTION 1.  Representations and Warranties.

     (a)  Representations and Warranties by the Company.  The Company
represents and warrants to each Underwriter, as of the date hereof and as of the
Closing Time referred to in Section 2(c) hereof, and as of the each Date of
Delivery (if any) referred to in Section 2(b) hereof, and agrees with each
Underwriter as follows:

                                       5
<PAGE>

          (i)    Compliance with Registration Requirements.  The Company meets
     the requirements for use of Form S-3 under the 1933 Act.  The Registration
     Statement has become effective under the 1933 Act and no stop order
     suspending the effectiveness of the Registration Statement has been issued
     under the 1933 Act and no proceedings for that purpose have been instituted
     or are pending or, to the knowledge of the Company, are contemplated by the
     Commission, and any request on the part of the Commission for additional
     information has been complied with.

          At the respective times the Registration Statement and 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 and at the Closing Time (as hereinafter
     defined) (and, if any Option Securities are purchased, at the Date of
     Delivery (as hereinafter defined)), the Registration Statement and any
     amendments thereto complied and will comply in all material respects with
     the requirements of the 1933 Act and the 1933 Act Regulations and did not
     and will not contain an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading.  At the date of the Prospectus and
     at the Closing Time (and, if any Option Securities are purchased, at the
     Date of Delivery), neither the Prospectus nor any amendments and
     supplements thereto included or will include an untrue statement of a
     material fact or omitted or will 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.  Notwithstanding the foregoing,
     the representations and warranties in this subsection shall not apply to
     statements in or omissions from the Registration Statement or the
     Prospectus made in reliance upon and in conformity with information
     furnished to the Company in writing by any Underwriter through Merrill
     Lynch or by any Selling Shareholder expressly for use in the Registration
     Statement or the Prospectus.

          Each preliminary prospectus and prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so
     filed in all material respects with the 1933 Act Regulations, and each
     preliminary prospectus and the Prospectus delivered to the Underwriters for
     use in connection with the offering of Securities will, at the time of such
     delivery, be identical to any electronically transmitted copies thereof
     filed with the Commission pursuant to EDGAR, except to the extent permitted
     by Regulation S-T.

          (ii)   Incorporated Documents.  The documents incorporated or deemed
     to be incorporated by reference in the Registration Statement and the
     Prospectus, when they became effective or at the time they were or
     hereafter are filed with the Commission, complied with and will comply in
     all material respects with the requirements of the 1934 Act and the rules
     and regulations of the Commission thereunder (the "1934 Act Regulations")
     and, when read together with the other information in the Prospectus, at
     the date of the Prospectus and at the Closing Time, did not and will not
     contain an untrue statement of

                                       6
<PAGE>

     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.

          (iii)  Independent Accountants.  The accountants who certified the
     financial statements and any supporting schedules thereto included in the
     Registration Statement and the Prospectus are independent public
     accountants as required by the 1933 Act and the 1933 Act Regulations.

          (iv)   Financial Statements.  The historical consolidated financial
     statements of the Company included in the Registration Statement and the
     Prospectus, together with the related schedules and notes, present fairly
     in all material respects the financial position of the Company and its
     consolidated subsidiaries at the dates indicated and the statements of
     operations, stockholders' equity and cash flows of the Company and its
     consolidated subsidiaries for the periods specified except, in the case of
     unaudited consolidated financial statements, for normal year end audit
     adjustments that have not been made and footnote disclosure necessary for
     GAAP (as defined below) purposes that may not have been presented.  The
     historical financial statements of each of the AlaTenn Subsidiaries and the
     El Paso Field Services Company - Anadarko Gas Gathering System included in
     the Registration Statement and the Prospectus pursuant to Rule 3-05 of
     Regulation S-X promulgated by the Commission ("Regulation S-X"), together
     with the related notes, present fairly in all material respects the
     financial position of the AlaTenn Subsidiaries (on a combined basis) and
     the El Paso Field Services Company - Anadarko Gas Gathering System at the
     respective dates indicated and for the periods specified except, in the
     case of unaudited consolidated financial statements, for normal year end
     audit adjustments that have not been made and footnote disclosure necessary
     for GAAP (as defined below) purposes that may not have been presented. Such
     financial statements have been prepared in conformity with generally
     accepted accounting principles ("GAAP") applied on a consistent basis
     throughout the periods involved.  The schedules supporting the historical
     financial statements of the Company and its consolidated subsidiaries, if
     any, included in the Registration Statement and the Prospectus present
     fairly and in all material respects in accordance with GAAP the information
     required to be stated therein.  The selected financial data and the summary
     financial information relating to the historical financial statements of
     the Company and its consolidated subsidiaries included in the Prospectus
     present fairly the information shown therein and have been compiled on a
     basis consistent with that of the audited financial statements included in
     the Registration Statement.

          (v)    No Material Adverse Change in Business.  Since the respective
     dates as of which information is given in the Registration Statement and
     the Prospectus, except as otherwise stated therein, (A) there has been no
     material adverse change in the condition, financial or otherwise, or in the
     earnings, business affairs or business prospects of the Company and its
     subsidiaries considered as one enterprise, whether or not arising in the
     ordinary course of business (a "Material Adverse Effect"), (B) there have
     been no transactions entered into by the Company or any of its
     subsidiaries, other than those in the

                                       7
<PAGE>

     ordinary course of business, which are material with respect to the Company
     and its subsidiaries considered as one enterprise, and (C) except for
     regular quarterly dividends on the Common Stock in amounts per share that
     are disclosed in the Prospectus, there has been no dividend or distribution
     of any kind declared, paid or made by the Company on any class of its
     capital stock.

          (vi)   Good Standing of the Company.  The Company has been duly
     organized and is validly existing as a corporation in good standing under
     the laws of the State of Nevada and has corporate power and authority to
     own, lease and operate its properties and to conduct its business as
     described in the Prospectus and to enter into and perform its obligations
     under, or as contemplated under, this Agreement.  The Company is duly
     qualified as a foreign corporation to transact business and is in good
     standing in each other jurisdiction in which such qualification is
     required, whether by reason of the ownership or leasing of property or the
     conduct of business, except where the failure to so qualify or be in good
     standing would not result in a Material Adverse Effect.

          (vii)  Good Standing of Subsidiaries.  Each "significant subsidiary"
     of the Company (as such term is defined in Rule 1-02 of Regulation S-X
     promulgated under the 1933 Act) is listed in Exhibit D of this Agreement
     (each, a "Subsidiary" and, collectively, the "Subsidiaries") and has been
     duly organized and is validly existing as a corporation in good standing
     under the laws of the jurisdiction of its incorporation, has corporate
     power and authority to own, lease and operate its properties and to conduct
     its business as described in the Prospectus and is duly qualified as a
     foreign corporation to transact business and is in good standing in each
     jurisdiction in which such qualification is required, whether by reason of
     the ownership or leasing of property or the conduct of business, except
     where the failure to so qualify or be in good standing would not result in
     a Material Adverse Effect.  Except as otherwise stated in the Registration
     Statement and the Prospectus, all of the issued and outstanding capital
     stock of each Subsidiary has been duly authorized and is validly issued,
     fully paid and non-assessable and, except for directors' qualifying shares,
     is owned by the Company, directly or through subsidiaries, free and clear
     of any security interest, mortgage, pledge, lien, encumbrance, claim or
     equity.  None of the outstanding shares of capital stock of any Subsidiary
     was issued in violation of preemptive or other similar rights of any
     security holder of such Subsidiary. The only other subsidiaries of the
     Company are certain other subsidiaries which, if considered in the
     aggregate as a single subsidiary, would not constitute a "significant
     subsidiary" as defined in Rule 1-02 of Regulation S-X.

          (viii) Capitalization.  The authorized, issued and outstanding
     capital stock of the Company is as set forth in the Prospectus in the

     subsequent issuances, if any, pursuant to this Agreement, pursuant to
     reservations, agreements or employee benefit plans referred to in the
     Prospectus or pursuant to the exercise of convertible securities or options
     referred to in the Prospectus and except for stock repurchases in the
     amount of not more than 27,000 shares).  The shares of issued and
     outstanding capital stock, including the Securities to be purchased by the

                                       8

     Underwriters from the Selling Shareholders, have been duly authorized and
     validly issued and are fully paid and non-assessable; none of the
     outstanding shares of capital stock, including the Securities to be
     purchased by the Underwriters from the Selling Shareholders, was issued in
     violation of the preemptive or other similar rights of any securityholder
     of the Company.

          (ix)   Authorization of this Agreement.  This Agreement has been duly
     authorized, executed and delivered by the Company.

          (x)    Authorization and Description of the Securities.  The
     Securities to be purchased by the Underwriters from the Company have been
     duly authorized for issuance and sale to the Underwriters pursuant to this
     Agreement and, when issued and delivered by the Company pursuant to this
     Agreement against payment of the consideration set forth herein, will be
     validly issued and fully paid and non-assessable; the Common Stock conforms
     to all statements relating thereto contained in the Prospectus and such
     description conforms to the rights set forth in the instruments defining
     the same; no holder of the Securities will be subject to personal liability
     by reason of being such a holder; and the issuance of the Securities is not
     subject to the preemptive or other similar rights of any securityholder of
     the Company.

          (xi)   Absence of Defaults and Conflicts.  Neither the Company nor
     any of its subsidiaries is in violation of its charter or by-laws or in
     default in the performance or observance of any obligation, agreement,
     covenant or condition contained in any contract, indenture, mortgage, deed
     of trust, loan or credit agreement, note, lease or other agreement or
     instrument to which the Company or any of its subsidiaries is a party or by
     which it or any of them may be bound, or to which any of the property or
     assets of the Company or any subsidiary is subject (collectively,
     "Agreements and Instruments") except for such defaults that would not
     result in a Material Adverse Effect; and the execution, delivery and
     performance of this Agreement and the consummation of the transactions
     contemplated herein and in the Registration Statement (including  the
     issuance and sale of the Securities and the use of the proceeds from the
     sale of the Securities as described in the Prospectus under the caption
     "Use of Proceeds") and compliance by the Company with its obligations
     hereunder have been duly authorized by all necessary corporate action and
     do not and will not, whether with or without the giving of notice or
     passage of time or both, conflict with or constitute a breach of, or
     default or Repayment Event (as defined below) under, or result in the
     creation or imposition of any lien, charge or encumbrance upon any property
     or assets of the Company or any subsidiary pursuant to, the Agreements and
     Instruments (except for such conflicts, breaches or defaults or liens,
     charges or encumbrances that would not result in a Material Adverse
     Effect), nor will such action result in any violation of the provisions of
     the charter or by-laws of the Company or any subsidiary or any applicable
     law, statute, rule, regulation, judgment, order, writ or decree of any
     government, government instrumentality or court, domestic or foreign,
     having jurisdiction over the Company or any subsidiary or any of their
     assets, properties or operations.  As used herein, a "Repayment

                                       9
<PAGE>

     Event" means any event or condition which gives the holder of any note,
     debenture or other evidence of indebtedness (or any person acting on such
     holder's behalf) the right to require the repurchase, redemption or
     repayment of all or a portion of such indebtedness by the Company or any
     subsidiary

          (xii)  Absence of Labor Dispute.  No labor dispute with the
     employees of the Company or any subsidiary exists or, to the knowledge of
     the Company, is imminent, and the Company is not aware of any existing or
     imminent labor disturbance by the employees of any of its or any
     subsidiary's principal suppliers, manufacturers, customers or contractors,
     which, in either case, may reasonably be expected to result in a Material
     Adverse Effect.

          (xiii) Absence of Proceedings.  There is no action, suit,
     proceeding, inquiry or investigation before or brought by any court or
     governmental agency or body, domestic or foreign, now pending, or, to the
     knowledge of the Company, threatened, against or affecting the Company or
     any Subsidiary, which is required to be disclosed in the Registration
     Statement (other than as disclosed therein), or which might reasonably be
     expected to result in a Material Adverse Effect, or which might reasonably
     be expected to materially and adversely affect the properties or assets
     thereof or the consummation of the transactions contemplated in this
     Agreement or the performance by the Company of its obligations hereunder;
     the aggregate of all pending legal or governmental proceedings to which the
     Company or any subsidiary is a party or of which any of their respective
     property or assets is the subject which are not described in the
     Registration Statement, including ordinary routine litigation incidental to
     the business, could not reasonably be expected to result in a Material
     Adverse Effect.

          (xiv)  Accuracy of Exhibits.  There are no contracts or documents
     which are required to be described in the Registration Statement, or the
     Prospectus or to be filed as exhibits thereto which have not been so
     described and filed as required.

          (xv)   Absence of  Further Requirements.  No filing with, or
     authorization, approval, consent, license, order, registration,
     qualification or decree of, any court or governmental authority or agency,
     domestic or foreign, is necessary or required for the due authorization,
     execution and delivery by the Company of this Agreement or for the
     performance by the Company of the transactions contemplated under the
     Prospectus, this Agreement, except  such as have been already made,
     obtained or rendered, as applicable or as may be required under the 1933

     (including trade secrets and other unpatented and/or unpatentable
     proprietary or confidential information, systems or procedures),
     trademarks, service marks, trade names or other intellectual property
     (collectively, "Intellectual

     neither the Company nor any of its subsidiaries has received any notice or
     is otherwise aware of any infringement of or conflict with asserted rights
     of others with respect to any Intellectual Property or of any facts or
     circumstances which would render any Intellectual Property invalid or
     inadequate to protect the interest of the Company or any of its
     subsidiaries therein, and which infringement or conflict (if the subject of
     any unfavorable decision, ruling or finding) or invalidity or inadequacy,
     singly or in the aggregate, would result in a Material Adverse Effect.

          (xvii)  Possession of Licenses and Permits.  The Company and its
     subsidiaries possess such permits, licenses, approvals, consents and other
     authorizations (collectively, "Governmental Licenses") issued by the
     appropriate federal, state, local or foreign regulatory agencies or bodies
     necessary to conduct the business now operated by them except for such
     Governmental Licenses which the failure to possess would not, singly or in
     the aggregate, have a Material Adverse Effect; the Company and its
     subsidiaries are in compliance with the terms and conditions of all such
     Governmental Licenses, except where the failure so to comply would not,
     singly or in the aggregate, have a Material Adverse Effect; all of the
     Governmental Licenses are valid and in full force and effect, except when
     the invalidity of such Governmental Licenses or the failure of such
     Governmental Licenses to be in full force and effect would not have a
     Material Adverse Effect; and neither the Company nor any of its
     subsidiaries has received any notice of proceedings relating to the
     revocation or modification of any such Governmental Licenses which, singly
     or in the aggregate, if the subject of an unfavorable decision, ruling or

     conditional instructions to deliver such Securities to the Underwriters
     pursuant to this Agreement.

          (ix)    No Association with NASD.  Neither such Selling Stockholder
     nor any of his affiliates directly, or indirectly through one or more
     intermediaries, controls, or is controlled by, or is under common control
     with, or has any other association with (within the meaning of Article I,
     Section 1(m) of the By-laws of the National Association of Securities
     Dealers, Inc.), any member firm of the National Association of Securities
     Dealers, Inc.

          In order to document the Underwriters' compliance with the reporting
and withholding provisions of the Tax Equity and Fiscal Responsibility Act of
1982 with respect to the transactions herein contemplated, each of the Selling
Shareholders agrees to deliver to Merrill Lynch prior to or at the Closing Time
a properly completed and executed United States Treasury Department Form W-9 (or
other applicable form or statement specified by Treasury Department regulations
in lieu thereof).

          Each of the Selling Shareholders specifically agrees that the
Securities to be held in custody for such Selling Shareholder under the Power of
Attorney and Custody Agreement will be subject to the interests of the
Underwriters hereunder, and that the arrangements made by such Selling
Shareholder for such custody, and the appointment by such Selling Shareholder of
the Attorney-in-Fact by the power of attorney contained in the Power of Attorney
and Custody Agreement, are to that extent irrevocable.  Each Selling Stockholder
specifically agrees that his obligations hereunder shall not be terminated by
operation of law, whether by the death or incapacity of such Selling
Shareholder.  If such Selling Shareholder or any such executor or trustee should
die or become incapacitated, or if any other such event should occur, before the
delivery of the Securities hereunder, certificates representing the Securities
shall be delivered by or on behalf of such Selling Shareholder in accordance
with the terms and conditions of this Agreement and of the Power of Attorney and
Custody Agreement, and actions taken by the Attorney-in-Fact pursuant to the
powers of attorney in the Power of Attorney and Custody Agreement shall be as
valid as if such death,  incapacity or other event had not occurred, regardless
of whether or not the Custodian, the Attorney-in-Fact, or any of them, shall
have received notice of such death, incapacity or other event.

                                       16

     (c)  Officer's Certificates.  Any certificate signed by any officer of
the Company or any of its subsidiaries delivered to the Representatives or to
counsel for the Underwriters pursuant to the terms of this Agreement shall be
deemed a representation and warranty by the Company to each Underwriter as to
the matters covered thereby; and any certificate signed by or on behalf of the
Selling Shareholders as such and delivered to the Representatives or to counsel
for the Underwriters pursuant to the terms of this Agreement shall be deemed a
representation and warranty by such Selling Shareholder to the Underwriters as
to the matters covered thereby.

     SECTION 2.   Sale and Delivery to Underwriters; Closing.

     (a)  Initial Securities.  On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein  set
forth, the Company and each Selling Shareholder, severally and not jointly,
agree to sell to each Underwriter, severally and not jointly, and each
Underwriter, severally and not jointly, agrees to purchase from the Company and
each Selling Shareholder, at the price per share set forth in Schedule C, that
proportion of the number of Initial Securities set forth in Schedule B opposite
the name of the Company or such Selling Shareholder, as the case may be, which
the number of Initial Securities set forth in Schedule A opposite the name of
such Underwriter, plus any additional number of Initial Securities which such
Underwriter may become obligated to purchase pursuant to the provisions of
Section 10 hereof, bears to the total number of Initial Securities, subject, in
each case, to such adjustments among the Underwriters as the Representatives in
their sole discretion shall make to eliminate any sales or purchases of
fractional securities.

     (b)  Option Securities.  In addition, on the basis of the representations
and warranties herein contained and subject to the terms and conditions herein
set forth, the Company hereby grants an option to the Underwriters, severally
and not jointly, to purchase up to an additional 519,000 shares of Common Stock,
as set forth in Schedule B, at the price per share set forth in Schedule C, less
an amount per share equal to any dividends or distributions declared by the
Company and payable on the Initial Securities but not payable on the Option
Securities.  The option hereby granted will expire 30 days after the date hereof
and may be exercised in whole or in part from time to time only for the purpose
of covering over-allotments which may be made in connection with the offering
and distribution of the Initial Securities upon notice by the Representatives to
the Company setting forth the number of Option Securities as to which the
several Underwriters are then exercising the option and the time and date of
payment and delivery for such Option Securities (if other than the Closing
Time).  Any such time and date of delivery (a "Date of Delivery") shall be
determined by the Representatives, but shall not be later than seven full
business days after the exercise of said option, nor in any event prior to the
Closing Time, as hereinafter defined.  If the option is exercised as to all or
any portion of the Option Securities, each of the Underwriters, acting severally
and not jointly, will purchase that proportion of the total number of Option
Securities then being purchased which the number of Initial Securities set forth
in Schedule A opposite the name of such Underwriter bears to the total number of
Initial Securities, subject in each case to such adjustments as the
Representatives in their discretion shall make to eliminate any sales or
purchases of fractional shares.

                                       17
<PAGE>

     (c)  Payment.  Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of Andrews
& Kurth L.L.P. or at such other place as shall be agreed upon by the
Representatives and the Company and the Selling Shareholders, at 8:30 a.m.
(Central time) on the third (fourth, if the pricing occurs after 4:30 p.m.
(Eastern time) on any given day) business day after the date hereof (unless
postponed in accordance with the provisions of Section 10), or such other time
not later than ten business days after such date as shall be agreed upon by the
Representatives and the Company and the Selling Shareholders (such time and date
of payment and delivery being herein called "Closing Time").

     In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates for, such Option Securities shall be made at the above-mentioned
offices, or at such other place as shall be agreed upon by the Representatives
and the Company, on each Date of Delivery as specified in the notice from the
Representatives to the Company.

     Payment shall be made to the Company and the Selling Shareholders by wire
transfer of immediately available funds to  bank accounts designated by the
Company and the Custodian pursuant to each Selling Shareholder's Power of
Attorney and Custody Agreement, as the case may be, against delivery to the
Representatives for the respective accounts of the Underwriters of certificates
for the Securities to be purchased by them.  It is understood that each
Underwriter has authorized the Representatives, for its account, to accept
delivery of, receipt for, and make payment of the purchase price for, the
Initial Securities and the Option Securities, if any, which it has agreed to
purchase.  Merrill Lynch, individually and not as representative of the
Underwriters, may (but shall not be obligated to) make payment of the purchase
price for the Initial Securities or the Option Securities, if any, to be
purchased by any Underwriter whose funds have not been received by the Closing
Time or the relevant Date of Delivery, as the case may be, but such payment
shall not relieve such Underwriter from its obligations hereunder.

     (d)  Denominations; Registration.  Certificates for the Initial
Securities and the Option Securities, if any, shall be in such denominations and
registered in such names as the Representatives may request in writing at least
two full business days before the Closing Time or the relevant Date of Delivery,
as the case may be.  The certificates for the Initial Securities and the Option
Securities, if any, will be made available for examination and packaging by the
Representatives in The City of New York not later than 10:00 a.m. (Eastern time)
on the business day prior to the Closing Time or the relevant Date of Delivery,
as the case may be.

     SECTION 3.   Covenants of the Company.  The Company covenants with each
Underwriter participating in the offering of Securities, as follows:

     (a)  Compliance with Securities Regulations and Commission Requests.  The
Company, subject to Section 3(b), will comply with the requirements of Rule 430A
of the 1933 Act Regulations and will notify the Representatives immediately, and
confirm the notice in writing, of (i) the effectiveness of any post-effective
amendment to the Registration Statement or the filing of any

                                       18
<PAGE>

supplement or amendment to the Prospectus, (ii) any request by the Commission
for any amendment to the Registration Statement or any amendment or supplement
to the Prospectus or for additional information, and (iii) the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus, or of the suspension of the qualification of the Securities for
offering or sale in any jurisdiction, or of the initiation or threatening of any
proceedings for any of such purposes. The Company will promptly effect the
filings necessary pursuant to Rule 424 of the 1933 Act Regulations and will take
such steps as it deems necessary to ascertain promptly whether the Prospectus
transmitted for filing under Rule 424 was received for filing by the Commission
and, in the event that it was not, it will promptly file the Prospectus. The
Company will make every reasonable effort to prevent the issuance of any stop
order and, if any stop order is issued, to obtain the lifting thereof at the
earliest possible moment.

     (b)  Filing of Amendments.  The Company will give the Representatives
notice of its intention to file or prepare any amendment to the Registration
Statement (including any filing under Rule 462(b)), any Term Sheet or any
amendment, supplement or revision to either the prospectus included in the
Registration Statement at the time it became effective or to the Prospectus,
whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the
Representatives with copies of any such documents a reasonable amount of time
prior to such proposed filing or use, as the case may be, and will not file or
use any such document to which the Representatives or counsel for the
Underwriters shall reasonably object.

     (c)  Delivery of Registration Statements.  The Company has furnished or
will deliver to the Representatives and counsel for the Underwriters, without
charge, signed copies of the Registration Statement as originally filed and of
each amendment thereto (including exhibits filed therewith or incorporated by
reference therein and documents incorporated or deemed to be incorporated by
reference therein) and signed copies of all consents and certificates of
experts, and will also deliver to the Representatives, without charge, a
conformed copy of the Registration Statement as originally filed and of each
amendment thereto (without exhibits) for each of the Underwriters.  The
Registration Statement and each amendment thereto furnished to the Underwriters
will be identical to any electronically transmitted copies thereof filed with
the Commission pursuant to EDGAR, except to the extent permitted by Regulation
S-T.

     (d)  Delivery of Prospectuses.  The Company has delivered to each
Underwriter, without charge, as many copies of each preliminary prospectus as
such Underwriter may reasonably request, and the Company hereby consents to the
use of such copies for purposes permitted by the 1933 Act.  The Company will
furnish to each Underwriter, without charge, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such
number of copies of the Prospectus as such Underwriter may reasonably request.
The Prospectus and any amendments or supplements thereto furnished to the
Underwriters will be identical to any electronically transmitted copies thereof
filed with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

                                       19
<PAGE>

     (e)  Continued Compliance with Securities Laws.  The Company will comply
with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act
Regulations so as to permit the completion of the distribution of the Securities
as contemplated in this Agreement and in the Registration Statement and the
Prospectus.  If at any time when the Prospectus is required by the 1933 Act or
the 1934 Act to be delivered in connection with sales of the Securities, any
event shall occur or condition shall exist as a result of which it is necessary,
in the opinion of counsel for the Underwriters or for the Company, to amend the
Registration Statement in order that the Registration Statement will not contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
or to amend or supplement the Prospectus in order that the Prospectus will not
include an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein not misleading in the light of
the circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of such counsel, at any such time to amend
the Registration Statement or amend or supplement the Prospectus in order to
comply with the requirements of the 1933 Act or the 1933 Act Regulations, the
Company will promptly prepare and file with the Commission, subject to Section
3(b), such amendment or supplement as may be necessary to correct such statement
or omission or to make the Registration Statement or the Prospectus comply with
such requirements, and the Company will furnish to the Underwriters, without
charge, such number of copies of such amendment or supplement as the
Underwriters may reasonably request.

     (f)  Blue Sky Qualifications.  The Company will use its reasonable
commercial efforts, in cooperation with the Underwriters, to qualify the
Securities for offering and sale under the applicable securities laws of such
states and other jurisdictions (domestic or foreign) as the Representatives may
designate and to maintain such qualifications in effect for a period of not less
than one year from the date of this Agreement; provided, however, that the
Company shall not be obligated to file any general consent to service of process
or to qualify as a foreign corporation or as a dealer in securities in any
jurisdiction in which it is not so qualified or to subject itself to taxation in
respect of doing business in any jurisdiction in which it is not otherwise so
subject.  In each jurisdiction in which the  Securities have been so qualified,
the Company will file such statements and reports as may be required by the laws
of such jurisdiction to continue such qualification in effect for a period of
not less than one year from the date of this Agreement.

     (g)  Earnings Statement.  The Company will timely file such reports
pursuant to the 1934 Act as are necessary in order to make generally available
to its securityholders an earnings statement for the purposes of, and to provide
the benefits contemplated by, the last paragraph of Section 11(a) of the 1933
Act.

     (h)  Use of Proceeds.  The Company will use the net proceeds received by
it from the sale of the  Securities in the manner specified in the Prospectus
under "Use of Proceeds."

     (i)  Restriction on Sale of Securities.  During a period of 180 days from
the date of the Prospectus, the Company will not, without the prior written
consent of Merrill Lynch on behalf of

                                       20
<PAGE>

the Underwriters, (i) directly or indirectly, offer, pledge, sell, sell short,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase or otherwise
transfer or dispose of any share of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock or file any registration
statement under the 1933 Act with respect to any of the foregoing (other than on
Form S-4 in connection with the acquisition of a business, Form S-8 or any
successor form) or (ii) enter into any swap or any other agreement or any
transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of the Common Stock, whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise. The foregoing
sentence shall not apply to (A) the Securities to be sold hereunder, (B) any
shares of Common Stock issued by the Company upon the exercise of an option or
warrant or the conversion of a security outstanding on the date hereof and
referred to in the Prospectus, (C) any shares of Common Stock issued or options
to purchase Common Stock granted pursuant to existing employee benefit plans of
the Company referred to in the Prospectus, (D) any shares of Common Stock issued
pursuant to any non-employee director stock plan or dividend reinvestment plan,
or (E) the issuance of unregistered shares of Common Stock in connection with
the Company's acquisition of a business provided that the transferee of such
shares shall be subject to a contractual transfer restriction similar to this
paragraph.

     (j)  Reporting Requirements.  The Company, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will
file all documents required to be filed with the Commission pursuant to the 1934
Act within the time periods required by the 1934 Act and the 1934 Act
Regulations.

     SECTION 4.   Payment of Expenses.

     (a)  Expenses. The Company will pay all expenses incident to the
performance of its obligations under this Agreement, including (i) the

Agreement, and such other documents as may be required in connection with the
offering, purchase, sale, issuance or delivery of the Securities, (iii) the

contemplated hereby are consummated or this Agreement is terminated, all costs

their out-of-pocket expenses, including the reasonable fees and disbursements of
counsel for the Underwriters.

affect any agreement that the Company and the Selling Shareholders may make for

     any untrue statement or alleged untrue statement of a material fact
     included in any preliminary prospectus or the Prospectus (or any amendment
     or supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)    against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such

                                       25
<PAGE>

     alleged untrue statement or omission; provided that (subject to Section
     6(d) below) any such settlement is effected with the written consent of the
     Company; and

          (iii)   subject to Section 6(c), against any and all expense
     whatsoever, as incurred (including the reasonable fees and disbursements of
     counsel chosen by the Representatives), reasonably incurred in
     investigating, preparing or defending against any litigation, or any
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through Merrill Lynch expressly for use in the Registration
Statement (or any amendment thereto), including the Rule 430A Information deemed
to be a part thereof, if applicable, or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto).

     (2)  Each of the Selling Shareholders, severally and not jointly, agrees to
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act against any and all loss, liability, claim, damage
and expense described in the indemnity contained in subsection (a)(1) of this
Section, as incurred, but only with respect to untrue statements or omissions,
or alleged untrue statements or omissions, made in the Registration Statement
(or any amendment thereto, including any Rule 424(b) Information and the Rule
430A Information deemed to be a part thereof, if applicable), or any preliminary
prospectus or the Prospectuses (or any amendment or supplement thereto) in
reliance upon and in conformity with information related to such Outside Selling
Shareholder furnished to the Company by such Outside Selling Shareholder
expressly for use in the Registration Statement (or any amendment thereto),
including the Rule 424(b) Information and the Rule 430A Information deemed to be
a part thereof, if applicable, or any preliminary prospectus or the Prospectuses
(or any amendment or supplement thereto); provided, however, that the liability
of such Outside Selling Shareholder under this subsection (a)(2) shall be
limited to an amount equal to the net proceeds (after deducting the
Underwriters' discount but before deducting expenses) received by such Outside
Selling Shareholder pursuant to the sale of its Securities hereunder.

     (b)  Indemnification of Company, Directors and Officers and Selling
Shareholders.  Each Underwriter severally agrees to indemnify and hold
harmless the Company, its directors, each of its officers who signed the
Registration Statement, and each person, if any, who controls the Company within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and
each Selling Shareholder and each person, if any, who controls any Selling
Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act, against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a)(1) of this Section, as

                                       26
<PAGE>

incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto), including the Rule 430A Information deemed to be a part
thereof, if applicable, or any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through Merrill Lynch
expressly for use in the Registration Statement (or any amendment thereto) or
such preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

     (c)  Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In case any such action is brought against any indemnified party and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party;
provided however, that if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded (based on advice of counsel in writing) that there may
be one or more legal defenses available to it and/or other indemnified parties
that are different from or additional to those available to the indemnifying
party, the indemnifying party shall not have the right to direct the defense of
such action on behalf of such indemnified party or parties and such indemnified
party or parties shall have the right to select separate counsel to defend such
action on behalf of such indemnified party or parties. After notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section 6 for any legal or other expenses, other than
reasonable costs of investigation, subsequently incurred by such indemnified
party in connection with the defense thereof, unless (i) the indemnified party
shall have employed separate counsel in accordance with the proviso to the next
preceding sentence (it being understood, however, that in connection with such
action the indemnifying party shall not be liable for the expenses of more than
one separate counsel (in addition to local counsel) in any one action or
separate but substantially similar actions in the same jurisdiction arising out
of the same general allegations or circumstances, designated by the
Representatives in the case of paragraph (a) of this Section 6, representing the
indemnified parties under such paragraph (a) who are parties to such action or
actions) or (ii) the indemnifying party does not promptly retain counsel
reasonably satisfactory to the indemnified party or (iii) the indemnifying party
has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party.  After such notice from the indemnifying
party to such indemnified party, the indemnifying party will not be liable for
the costs and expenses of any settlement of such action effected by such
indemnified party without the consent of the indemnifying party .  No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any

                                       27
<PAGE>

claim whatsoever in respect of which indemnification or contribution could be
sought under this Section 6 or Section 7 hereof (whether or not the indemnified
parties are actual or potential parties thereto), unless such settlement
compromise or consent (i) includes an unconditional release of each indemnified
party from all liability arising out of such litigation, investigation,
proceeding or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act by or on behalf of any indemnified
party.

     (d)  Settlement without Consent if Failure to Reimburse.  Subject to
Section 6(c), if at any time an indemnified party shall have requested an
indemnifying party to reimburse the 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 6(a)(1)(ii) effected without
its written consent if (i) such settlement is entered into more than 45 days
after receipt by such indemnifying party of the aforesaid request, (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 prior to the date of such settlement.

     (e)  Other Agreements with Respect to Indemnification.  The provisions of
this Section shall not affect any agreement among the Company and the Selling
Shareholders with respect to indemnification.

     SECTION 7.   Contribution. If the indemnification provided for in Section
6 hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, labilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Selling Shareholders, on the one hand, and the Underwriters, on the other hand,
from the offering of the  Securities pursuant to this Agreement or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company and the
Selling Shareholders, on the one hand, and of the Underwriters, on the other
hand, in connection with the statements or omissions which resulted in such
losses, liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

     The relative benefits received by the Company and the Selling Shareholders,
on the one hand, and the Underwriters, on the other hand, in connection with the
offering of the  Securities pursuant to this Agreement shall be deemed to be in
the same respective proportions as the total net proceeds from the offering of
such  Securities (before deducting expenses) received by the Company and the
Selling Shareholders and the total underwriting discount received by the
Underwriters, in each case as set forth on the cover of the Prospectus, bear to
the aggregate initial public offering price of such  Securities as set forth on
such cover.

                                       28
<PAGE>

     The relative fault of the Company and the Selling Shareholders, on the one
hand, and the Underwriters, on the other hand, shall be determined by reference
to, among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Selling Shareholders or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     The Company, the Selling Shareholders and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
7. The aggregate amount of losses, liabilities, claims, damages and expenses
incurred by an indemnified party and referred to above in this Section 7 shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of any 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.

     For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company or any
Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to contribution as the Company or
such Selling Shareholder, as the case may be.  The Underwriters' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the number of Initial Securities set forth opposite their respective names in
Schedule A hereto and not joint.

     Any party entitled to contribution will, promptly after receipt of notice
of commencement of any action, suit or proceeding against such party in respect
of which a claim for contribution may be made against another party or parties
under this Section 7, notify such party or parties from whom contribution may be
sought, but the omission so to notify such party or parties from whom
contribution may be sought shall not relieve the party or parties from whom
contribution may be

                                       29
<PAGE>

sought from any other obligation it or they may have hereunder or otherwise than
under this Section 7.

     The provisions of this Section shall not affect any agreement among the
Company and the Selling Shareholders with respect to contribution.

     SECTION 8.   Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or the Selling
Shareholders submitted pursuant hereto shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of any
Underwriter or controlling person, or by or on behalf of the Company or the
Selling Shareholders, and shall survive delivery of the Securities to the
Underwriters.

     SECTION 9.   Termination of Agreement.

     (a)  Termination; General. The Representatives may terminate this
Agreement, by notice to the Company and the Selling Shareholders, at any time at
or prior to the Closing Time, if (i)  there has been, since the time of
execution of this Agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
there has occurred any material adverse change in the financial markets in the
United States, any outbreak of hostilities or escalation thereof or other
calamity or crisis or any change or development involving a prospective change
in national or international political, financial or economic conditions, in
each case the effect of which is such as to make it, in the judgment of the
Representatives, impracticable to market the  Securities or to enforce contracts
for the sale of the  Securities, or (iii) trading in any securities of the
Company has been suspended or materially limited by the Commission or by the
American Stock Exchange, or if trading generally on the New York Stock Exchange
or the American Stock Exchange or in the Nasdaq National Market has been
suspended or materially limited, or minimum or maximum prices for trading have
been fixed, or maximum ranges for prices have been required, by either of said
exchanges or by such system or by order of the Commission, the NASD or any other
governmental authority, or (iv) a banking moratorium has been declared by either
Federal or New York authorities.

     (b)  Liabilities. If this Agreement is terminated pursuant to this
Section , such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6, 7 and 8 shall survive such termination and remain in full force and
effect.

     SECTION 10.  Default by One or More of the Underwriters.  If one or more
of the Underwriters shall fail at the Closing Time or a Date of Delivery to
purchase the  Securities which it or they are obligated to purchase under this
Agreement (the "Defaulted Securities"), the Representatives shall have the
right, within 24 hours thereafter, to make arrangements for one or

                                       30
<PAGE>

more of the non-defaulting Underwriters, or any other underwriters, to purchase
all, but not less than all, of the Defaulted Securities in such amounts as may
be agreed upon and upon the terms herein set forth; if, however, the
Representatives shall not have completed such arrangements within such 24-hour
period, then:

          (a) if the number of Defaulted Securities does not exceed 10% of the
     aggregate principal amount of Securities to be purchased on such date, each
     of the non-defaulting Underwriters shall be obligated, severally and not
     jointly, to purchase the full amount thereof in the proportions that their
     respective underwriting obligations hereunder bear to the underwriting
     obligations of all non-defaulting Underwriters, or

          (b) if the number of Defaulted Securities exceeds 10% of the
     aggregate principal amount of  Securities to be purchased on such date this
     Agreement or, with respect to any Date of Delivery which occurs after the
     Closing Time, the Company shall have one additional business day within
     which it may, but is not obligated to, find one or more substitute
     underwriters reasonably satisfactory to the Representatives to purchase the
     Defaulted Securities upon the terms set forth in this Agreement and if the
     Company is unable, or elects not, to find such substitute underwriters
     within said one business day period, the obligation of the Underwriters to
     purchase and of the Company to sell the Option Securities to be purchased
     and sold on such Date of Delivery, shall terminate without liability on the
     part of any non-defaulting Underwriter.

     No action taken pursuant to this Section 10 shall relieve any defaulting
Underwriter from liability in respect of its default.  A substitute underwriter
shall become an Underwriter for all purposes of this Agreement.

     In the event of any such default which does not result in a termination of
this Agreement or, in the case of a Date of Delivery which is after the Closing
Time, which does not result in a termination of the obligation of the
Underwriters to purchase and the Company to sell the relevant Option Securities,
as the case may be,  either (i) the Representatives or (ii) the Company and the
Selling Shareholders shall have the right to postpone the Closing Time for a
period not exceeding seven days in order to effect any required changes in the
Registration Statement or the Prospectus or in any other documents or
arrangements.  As used herein, the term "Underwriter" includes any person
substituted for an Underwriter under this Section 10.

     SECTION 11.  Default by One or More of the Selling Shareholders or the
Company.

     (a)  If a Selling Shareholder shall fail at Closing Time or at a Date of
Delivery to sell and deliver the number of Securities which such Selling
Shareholder or Selling Shareholders are obligated to sell hereunder, and the
remaining Selling Shareholders do not exercise the right hereby granted to
increase, pro rata or otherwise, the number of Securities to be sold by them
hereunder to the total number to be sold by all Selling Shareholders as set
forth in Schedule B hereto, then the Underwriters may, at option of the
Representatives, by notice from the Representatives to the

                                       31
<PAGE>

Company and the non-defaulting Selling Shareholders, either (a) terminate this
Agreement without any liability on the fault of any non-defaulting party except
that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and
effect or (b) elect to purchase the Securities which the non-defaulting Selling
Shareholders and the Company have agreed to sell hereunder. No action taken
pursuant to this Section 11 shall relieve any Selling Shareholder so defaulting
from liability, if any, in respect of such default.

     In the event of a default by any Selling Shareholder as referred to in this
Section 11, each of the Representatives,  the Company and the non-defaulting
Selling Shareholders shall have the right to postpone Closing Time or Date of
Delivery for a period not exceeding seven days in order to effect any required
change in the Registration Statement or Prospectus or in any other documents or
arrangements.

     (b)  If the Company shall fail at Closing Time or at the Date of Delivery
to sell the number of Securities that it is obligated to sell hereunder, then
this Agreement shall terminate without any liability on the part of any
nondefaulting party; provided, however, that the provisions of Sections 1, 4, 6,
7 and 8 shall remain in full force and effect.  No action taken pursuant to this
Section shall relieve the Company from liability, if any, in respect of such
default.

     SECTION 12.  Notices. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the
Underwriters shall be directed to Merrill Lynch at World Financial Center, North
Tower, New York, New York 10281-1201, attention of Ira H. Green, Jr.; notices to
the Company shall be directed to it at 1100 Louisiana Street, Suite 2950,
Houston, Texas 77002, attention of Dan C. Tutcher, President; and notices to any
of the Selling Shareholders shall be directed to Dan C. Tutcher, Custodian, 1100
Louisiana Street, Suite 2950, Houston, Texas 77002.

     SECTION 13.  Parties. This Agreement shall inure to the benefit of and
be binding upon the Underwriters, the Company and the Selling Shareholders and
their respective successors.  Nothing expressed or mentioned in this Agreement
is intended or shall be construed to give any person, firm or corporation, other
than the Underwriters, the Company and the Selling Shareholders and their
respective successors and the controlling persons and officers and directors
referred to in Sections 6 and 7 and their heirs and legal representatives, any
legal or equitable right, remedy or claim under or in respect of this Agreement
or any provision herein contained.  This Agreement and all conditions and
provisions hereof are intended to be for the sole and exclusive benefit of the
Underwriters, the Company and the Selling Shareholders and their respective
successors, and said controlling persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm or
corporation.  No purchaser of Securities from any Underwriter shall be deemed to
be a successor by reason merely of such purchase.

     SECTION 14. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

corporation in good standing under the laws of the State of Nevada.

    (ii)    The Company has corporate power and authority to own, lease and
operate its properties and to conduct its business as described in the
Prospectus and to enter into and perform its obligations under the Purchase
Agreement.

    (iii)   The Company is duly qualified as a foreign corporation to transact
business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or

    (iv)    The authorized, issued and outstanding capital stock of the Company
is as set forth in the Prospectus in the column entitled "Actual" under the
caption "Capitalization" (except for subsequent issuances, if any, pursuant to
the Purchase Agreement or pursuant to reservations, agreements or employee
benefit plans referred to in the Prospectus or pursuant to the exercise of
convertible securities or options referred to in the Prospectus and except for
27,000 shares that have been repurchased by the Company since March 31, 1999 as
treasury shares); the shares of issued and outstanding capital stock of the
Company, including the Securities to be purchased by the Underwriters from the
Selling Shareholders, have been duly authorized and validly issued and are fully
paid and non-assessable; and none of the outstanding shares of capital stock of
the Company was issued in violation of the preemptive or other similar rights of
any securityholder of the Company.

    (v)     The Securities to be purchased by the Underwriters from the Company
have been duly authorized for issuance and sale to the Underwriters pursuant to

of the Securities by the Selling Shareholders is not subject to the preemptive
or other similar rights of any securityholder of the Company.

    (vii)   Each Subsidiary has been duly incorporated or organized and is
validly existing in good standing under the laws of the jurisdiction of its
formation, has power and authority to own, lease and operate its properties and
to conduct its business as described in the Prospectus and is duly qualified as
a foreign entity to transact business and is in good standing in each
jurisdiction in which such qualification is required, whether by reason of the
ownership or leasing of property or the conduct of business, except where the
failure so to qualify or to be in good standing would not result in a Material
Adverse Effect; except as otherwise disclosed in the Registration Statement, all
of the issued and outstanding capital stock of each Subsidiary has been duly
authorized and validly issued, is fully paid and non-assessable and, to the best
of our knowledge, is owned by the Company, directly or through subsidiaries,
free and clear of any security interest, mortgage, pledge, lien, encumbrance,
claim or equity; none of the outstanding shares of capital stock of any
Subsidiary was issued in violation of the preemptive or similar rights of any
securityholder of such Subsidiary.

    (viii)  The Purchase Agreement has been duly authorized, executed and
delivered by the Company.

    (ix)    The Registration Statement has been declared 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 best of our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued under the 1933 Act and no proceedings for
that purpose have been instituted or are pending or threatened by the
Commission.

    (x)     The Registration Statement, the Rule 430A Information, as
applicable, the Prospectus, and each amendment or supplement to the Registration
Statement and Prospectus, as of their respective effective or issue dates (other
than the financial statements and supporting schedules included therein or
omitted therefrom, as to which we need express no opinion) complied as to form
in all material respects with the requirements of the 1933 Act and the 1933 Act
Regulations.

    (xi)    The form of certificate used to evidence the Common Stock complies
in all material respects with all applicable statutory requirements, with any
applicable requirements of the charter and by-laws of the Company and the
requirements of the American Stock Exchange.

    (xii)   To the best of our knowledge, except as disclosed in the Prospectus,
there is not pending or threatened any action, suit, proceeding, inquiry or
investigation, to which the Company or any subsidiary is a party, or to which
the property of the Company or any subsidiary is subject, before or brought by
any court or governmental agency or body, domestic or foreign, which might
reasonably be expected to result in a Material Adverse Effect, or which might
reasonably be expected to materially and adversely affect the properties or
assets thereof or the consummation of the transactions contemplated in the
Purchase Agreement or the performance by the Company of its obligations
thereunder.

    (xiii)  The information in the Prospectus under "Description of Capital
Stock--Common Stock" and in the supplement constituting part of the Prospectus
under "Business--Regulatory Matters" and in the Registration Statement under
Item 15, to the extent that it constitutes matters of




                                      A-2

<PAGE>

law, summaries of legal matters, the Company's charter and bylaws or legal
proceedings, or legal conclusions, has been reviewed by us and is correct in all
material respects.

    (xiv)   All descriptions in the Registration Statement of contracts and
other documents to which the Company or its subsidiaries are a party are
accurate in all material respects; to the best of our knowledge, there are no
franchises, contracts, indentures, mortgages, loan agreements, notes, leases or
other instruments required to be described or referred to in the Registration
Statement or to be filed as exhibits thereto other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the descriptions thereof or references thereto are correct in all material
respects.

    (xv)    To the best of our knowledge, neither the Company nor any subsidiary
is in violation of its charter or by-laws and no default by the Company or any
subsidiary exists in the due performance or observance of any material
obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument that is described or referred to in the Registration Statement or the
Prospectus or filed or incorporated by reference as an exhibit to the
Registration Statement where the consequences of such default might reasonably
be expected to result in a Material Adverse Effect.

    (xvi)   No filing with, or authorization, approval, consent, license, order,
registration, qualification or decree of, any court or governmental authority or
agency, domestic or foreign (other than under the 1933 Act and the 1933 Act
Regulations, which have been obtained, or as may be required under the
securities or blue sky laws of the various states, as to which we express no
opinion) is necessary or required in connection with the due authorization,
execution and delivery of the Purchase Agreement or for the offering, issuance,
sale or delivery of the Securities.

    (xvii)  The execution, delivery and performance of the Purchase Agreement
and the consummation of the transactions contemplated in the Purchase Agreement
and in the Registration Statement (including the issuance and sale of the
Securities and the use of the proceeds from the sale of the Securities as
described in the Prospectus under the caption "Use Of Proceeds") and compliance
by the Company with its obligations under the Purchase Agreement do not and will
not, whether with or without the giving of notice or lapse of time or both,
conflict with or constitute a breach of, or default or Repayment Event (as
defined in Section 1(a)(xi) of the Purchase Agreement) under or result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the Company or any subsidiary pursuant to any contract, indenture,
mortgage, deed of trust, loan or credit agreement, note, lease or any other
agreement or instrument, known to us, to which the Company or any subsidiary is
a party or by which it or any of them may be bound, or to which any of the
property or assets of the Company or any subsidiary is subject (except for such
conflicts, breaches or defaults or liens, charges or encumbrances that would not
have a Material Adverse Effect), nor will such action result in any violation of
the provisions of the charter or by-laws of the Company or any subsidiary, or
any applicable law, statute, rule, regulation, judgment, order, writ or decree,
known to us, of any government, government instrumentality or court,


                                      A-3

<PAGE>

domestic or foreign, having jurisdiction over the Company or any subsidiary or
any of their respective properties, assets or operations.

    (xviii)  To the best of our knowledge, except as disclosed in the
Prospectus, there are no persons with registration rights or other similar
rights to have any securities registered pursuant to the Registration Statement
or otherwise registered by the Company under the 1933 Act.

          Although we are not passing upon and do not assume any responsibility
for the accuracy, completeness or fairness of the statements contained in the
Prospectus or Registration Statement (except as specified in the foregoing
opinion), nothing has come to our attention that would lead us to believe that
the Registration Statement or any amendment thereto, including the Rule 430A
Information (if applicable), (except for financial statements and schedules and
other financial data included therein or omitted therefrom, as to which we need
make no statement), at the time such Registration Statement or any such
amendment became effective, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus or any
amendment or supplement thereto (except for financial statements and schedules
and other financial data included therein or omitted therefrom, as to which we
need make no statement), at the time the Prospectus was issued, at the time any
such amended or supplemented prospectus was issued or at the Closing Time,
included or includes an 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.

          In rendering such opinion, such counsel may rely (A) as to matters
involving the application of the laws of Nevada, upon the opinion of Woodburn
and Wedge, special counsel to the Company (which opinion shall be dated and
furnished to the Representatives at the Closing Time, shall be satisfactory in
form and substance to counsel for the Underwriters and shall expressly state
that the Underwriters may rely on such opinion as if it were addressed to them),
provided that Porter & Hedges, L.L.P. shall state in their opinion that they
believe that they and the Underwriters are justified in relying upon such
opinion, (B), as to matters of fact (but not as to legal conclusions), to the
extent they deem proper, on certificates of responsible officers of the Company
and public officials.  Such opinion shall not state that it is to be governed or
qualified by, or that it is otherwise subject to, any treatise, written policy
or other document relating to legal opinions, including, without limitation, the
Legal Opinion Accord of the ABA Section of Business Law (1991).  In rendering
such opinion, matters expressly stated as within the "knowledge" of counsel
shall be limited to matters within the knowledge of the attorneys of such
counsel's firm who have rendered substantive attention to matters for the
Company and its subsidiaries.

pursuant to, any contract, indenture, mortgage, deed of trust, loan or credit
agreement, note, license, lease or other instrument or agreement to which any
Selling Shareholder is a party or by which he may be bound, or to which any of

    (vi)    To the best of our knowledge, each Selling Shareholder has good and

Shareholder and who are otherwise bona fide purchasers for purposes of the
Uniform Commercial Code) valid and marketable title to such Securities, free and
clear of any pledge, lien, security interest, charge, claim, equity or
encumbrance of any kind.
