Company 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 said Schedule A and with respect
to the grant by the Company to the Underwriters, acting severally and not

3,450,000 additional shares of Common Stock to cover over-allotments, in each
case except as may otherwise be provided in the Pricing Agreement, as
hereinafter defined.  The 23,000,000 shares of Common Stock (the "Initial
Securities") to be purchased by the Underwriters and all or any of the
3,450,000 shares of Common Stock subject to the option described in Section
2(b) hereof (the "Option Securities") are collectively hereinafter called the
"Securities."
   3
         Prior to the purchase and public offering of the Securities by the
several Underwriters, the Company and the Representatives, acting on behalf of
the several Underwriters, shall enter into an agreement substantially in the
form of Exhibit A hereto (the "Pricing Agreement").  The Pricing Agreement may
take the form of an exchange of any standard form of written telecommunication
between the Company and the Representatives and shall specify such applicable
information as is indicated in Exhibit A hereto.  The offering of the
Securities will be governed by this Agreement, as supplemented by the Pricing
Agreement.  From and after the date of the execution and delivery of the
Pricing Agreement, this Agreement shall be deemed to incorporate the Pricing
Agreement.

         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33- _______) and a
related preliminary prospectus for the registration of the Securities under the
Securities Act of 1933, as amended (the "1933 Act"), has filed each such
amendment thereto, if any, and each such amended prospectus as may have been
required to the date hereof, and will file such additional amendments thereto
and such amended prospectuses as may hereafter be required.  Such registration
statement (as amended, if applicable) and the prospectus constituting a part
thereof (including in each case all documents filed by the Company pursuant to
the Securities Exchange Act of 1934, as amended (the "1934 Act"), that are
incorporated by reference therein and the information, if any, deemed to be a
part thereof pursuant to Rule 430A(b) of the rules and regulations of the
Commission under the 1933 Act (the "1933 Act Regulations")), as from time to
time amended or supplemented pursuant to the 1933 Act or otherwise, are
hereinafter referred to as the "Registration Statement" and the "Prospectus",
respectively, except that if any revised prospectus shall be provided to the
Underwriters by the Company in connection with the offering of the Securities
which differs from the Prospectus on file at the Commission at the time the
Registration Statement becomes effective (whether or not such revised
prospectus is required to be filed by the Company pursuant to Rule 424(b) of
the 1933 Act Regulations), the term "Prospectus" shall refer to such revised
prospectus from and after the time it is first provided to the Underwriters for
such use.  All references in this Agreement to financial statements and
schedules and other information which are "contained," "included" or "stated"
in the Registration Statement or the Prospectus (and all other references of
like import) shall be deemed to mean and include all such financial statements
and schedules and other information which are or are deemed to be incorporated
by reference in the Registration Statement or the Prospectus, as the case may
be; and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include
the filing of any document under the 1934 Act which is or is deemed to be
incorporated by reference in the Registration Statement or the Prospectus, as
the case may be.

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

         (a)     The Company represents and warrants to each Underwriter as of
the date hereof and, if later than the date hereof, as of the date of the
Pricing Agreement (such latter date being hereinafter referred to as the
"Representation Date") as follows:

                 (1)      At the time the Registration Statement becomes
         effective and at the Representation Date, the Registration Statement
         will comply in all material respects with the requirements of the 1933
         Act and the 1933 Act Regulations and will not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or





                                      -2-
   4
         necessary to make the statements therein not misleading.  The
         Prospectus, at the Representation Date and at each Closing Time
         referred to in Section 2 hereof, 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, in the light of the circumstances
         under which they were made, not misleading; provided, however, that
         the representations and warranties in this subsection shall not apply
         to statements in or omissions from the Registration Statement or
         Prospectus made in reliance upon and in conformity with information
         furnished to the Company in writing by any Underwriter through the
         Representatives expressly for use in the Registration Statement or
         Prospectus.

         by the 1933 Act and the 1933 Act Regulations.

                 (3)      The consolidated financial statements, including the
         notes thereto, and financial statement schedules included in the
         Registration Statement and the Prospectus present fairly the

         of the dates indicated and the results of their operations and cash
         flows for the periods specified in conformity with generally accepted
         accounting principles applied, except as otherwise stated in the
         Registration Statement, on a consistent basis; and the financial
         statement schedules included in the Registration Statement present
         fairly the information required to be stated therein.  The selected
         financial data included in the Registration Statement and the
         Prospectus present fairly the information shown therein and have been
         compiled on a basis consistent with that of the audited consolidated
         financial statements included therein.

                 (4)      Since the respective dates as of which information is
         given in the Prospectus, except as otherwise stated or contemplated

         course of business, (ii) there have been no transactions entered into

         its business, except where the failure to so qualify or be in good
         standing would not have a material adverse effect on the condition,
         financial or otherwise, or the earnings, business affairs or business
         prospects of the Company and its subsidiaries considered as one
         enterprise.

         determined, shall be set forth in the Pricing Agreement and the
         Prospectus.  In the event that such prices have not been agreed upon
         and the Pricing Agreement has not been executed and delivered by all
         parties thereto by the close of business on the fourth business day
         following the date of this Agreement, this Agreement shall terminate
         forthwith, without liability of any party to any other party, unless
         otherwise agreed to by the Company and the Representatives.

                 (b)      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 3,450,000 shares of Common Stock at the price per share set
         forth in the Pricing Agreement.  The option hereby granted will expire
         30 days after the Representation Date, and may be exercised in whole
         or in part at any 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 Underwriters are exercising the option and
         the time and date of payment and delivery for such Option Securities.
         Such time and date of delivery for the Option Securities (the "Second
         Closing Time") shall be determined by the Representatives, but shall
         not be later than seven full business days after the exercise of said
         option, and in no event prior to the First Closing Time, as
         hereinafter defined, unless otherwise agreed by the Representatives
         and the Company.  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 (except as
         otherwise provided in the Pricing Agreement), subject in each case to
         such adjustments as the Representatives in their discretion shall make
         to eliminate any sales or purchases of fractional shares.

                 (c)      Payment of the purchase price for, and delivery of
         certificates for, the Initial Securities shall be made at the office
         of Merrill Lynch & Co., Merrill Lynch World Headquarters, North Tower,
         World Financial Center, New York, New York 10281, or at such other
         place as shall be agreed upon by the Representatives and the Company,
         at 10:00 A.M. on the fifth business day after execution of the Pricing
         Agreement, or such other time not later than ten business days after
         such date as shall be agreed upon by the Representatives and the
         Company (such time and date of payment and delivery being herein
         called the "First Closing





                                      -7-
   9
         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 of Merrill Lynch & Co.,
         or at such other place as shall be agreed upon by the Representatives
         and the Company, at the Second Closing Time as specified in the notice
         from the Representatives to the Company.  Each of the First Closing
         Time and the Second Closing Time is herein called a "Closing Time."
         Payment shall be made to the Company by certified or official bank
         check or checks drawn in New York Clearing House funds, or by wire
         transfer into one or more accounts designated by the Company or
         similar next day funds payable to the order of the Company against
         delivery to the Representatives for the respective accounts of the
         Underwriters of certificates for the Securities to be purchased by
         them.  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
         business days before the Closing Time at which such certificates are
         to be delivered.  It is understood that each Underwriter has
         authorized the Representatives, for their 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.  The Representatives, individually and not as
         representatives 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 check has not been received by the First Closing Time or the
         Second Closing Time, as the case may be, but such payment shall not
         relieve such Underwriter from its obligations hereunder.  The
         certificates for the Initial Securities and the Option Securities, if
         any, will be made available for examination and packaging by the
         Representatives not later than 10:00 A.M. on the last business day
         prior to the Closing Time at which such certificates are to be
         delivered.

         SECTION 3. COVENANTS OF THE COMPANY.  The Company covenants with each
Underwriter as follows:

                 (a)      The Company will notify the Representatives
         immediately, and confirm the notice in writing, (i) of the
         effectiveness of the Registration Statement and any amendment thereto,
         (ii) of the receipt of any comments from the Commission, (iii) of 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 (iv) of the issuance by the Commission of
         any stop order suspending the effectiveness of the Registration
         Statement or the initiation of any proceedings for that purpose.  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)      The Company will give the Representatives notice of
         its intention to file or prepare any amendment to the Registration
         Statement (including any document incorporated by reference therein
         and any post-effective amendment) or any amendment or supplement to
         the Prospectus (including any document incorporated by reference
         therein and any revised prospectus that the Company proposes for use
         by the Underwriters in connection with the offering of the Securities
         which differs from the prospectus on file at the Commission at the
         time the Registration Statement becomes effective, whether or not such
         revised prospectus is required to be filed pursuant to Rule 424(b) of
         the 1933 Act Regulations), will furnish the Representatives copies of
         any such amendment or supplement a reasonable amount of time prior to
         such proposed filing or use, as the case may be, and will not file any
         such amendment or supplement,





                                      -8-
   10
         except as required by Section 3(e), or use any such prospectus to
         which the Representatives or counsel for the Underwriters shall
         object.

                 (c)      The Company will deliver to the Representatives five
         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 will also deliver to the
         Representatives one conformed copy of the Registration Statement as
         originally filed and of each amendment thereto (without exhibits) for
         each of the Underwriters.

                 (d)      The Company will furnish to each Underwriter, from
         time to time 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 amended or supplemented) as such Underwriter may
         reasonably request for the purposes contemplated by the 1933 Act or
         the 1934 Act or the respective applicable rules and regulations of the
         Commission thereunder.

                 (e)      If any event shall occur as a result of which it is
         necessary, in the opinion of counsel for the Company or counsel for
         the Underwriters, to amend or supplement the Prospectus in order to
         make the Prospectus not misleading in the light of the circumstances
         existing at the time it is delivered to a purchaser, the Company will
         forthwith amend or supplement the Prospectus so that, as so amended or
         supplemented, the Prospectus will not include any untrue statement of
         a material fact or omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances
         existing at the time it is delivered to a purchaser, not misleading,
         and the Company will furnish to the Underwriters a reasonable number
         of copies of such amendment or supplement.

                 (f)      The Company will endeavor, in cooperation with the
         Underwriters and their counsel, to qualify the Securities for offering
         and sale under the applicable securities laws of such states and other
         jurisdictions of the United States as the Representatives may
         designate; provided, however, that the Company shall not be obligated
         to qualify as a foreign corporation in any jurisdiction in which it is
         not so qualified.  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 effective date of the Registration Statement.

                 (g)      The Company will make generally available to its
         security holders as soon as practicable, but not later than 50 days
         after the close of the period covered thereby, an earnings statement
         (in form complying with the provisions of Rule 158 of the 1933 Act
         Regulations) covering a period of at least twelve months beginning not
         later than the first day of the Company's fiscal quarter next
         following the effective date (as defined in said Rule 158) of the
         Registration Statement.

                 (h)      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)      If, at the time that the Registration Statement
         becomes effective, any information shall have been omitted therefrom
         in reliance upon Rule 430A of the 1933 Act Regulations, then,
         immediately following the execution of the Pricing Agreement, the
         Company will prepare, and file or transmit for filing with the
         Commission, in accordance with such Rule 430A and





                                      -9-
   11
         Rule 424(b) of the 1933 Act Regulations, copies of an amended
         Prospectus or, if required by such Rule 430A, a post-effective
         amendment to the Registration Statement (including an amended
         Prospectus), containing all information so omitted.

                 (j)      The Company will use its best efforts to cause the
         Securities to be duly authorized for listing on the New York Stock
         Exchange, subject to official notice of issuance, on or before the
         Closing Time at which such Securities are to be delivered hereunder.

                 (k)      For a period of five years from the Representation
         Date, the Company will furnish to the Representatives as soon as they
         are publicly available copies of all annual, quarterly and current
         reports that it shall file with the Commission on Forms 10-K, 10-Q and
         8-K or such other similar forms as may be designated by the
         Commission, and such other documents, reports and information as shall
         be furnished by the Company to its public stockholders generally.

                 (l)      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
         Section 13, 14 or 15 of the 1934 Act within the time periods required
         by the 1934 Act and the 1934 Act Regulations.

                 (m)      During a period of 120 days from the Representation
         Date, the Company will not, without Merrill Lynch's prior written
         consent, directly or indirectly, offer, sell or otherwise dispose of
         any shares of Common Stock or securities convertible into or
         exercisable for Common Stock, except that the Company may, without
         such consent, issue shares of Common Stock upon the exercise of
         options under its stock option plan and may grant stock options
         thereunder.

         SECTION 4.       PAYMENT OF EXPENSES.  The Company will pay all
expenses incident to the performance of its obligations under this Agreement,
including (i) the printing and filing of the Registration Statement as
originally filed and of each amendment thereto, (ii) the reproduction of this
Agreement and the Pricing Agreement, (iii) the preparation, issuance and
delivery of the certificates for the Securities to the Underwriters, (iv) the
fees and disbursements of the Company's counsel, engineers and accountants, (v)
the qualification of the Securities under securities laws in accordance with
the provisions of Section 3(f) hereof, including filing fees and the fees and
disbursements of counsel for the Underwriters in connection therewith and in
connection with the preparation of the Blue Sky Survey, (vi) the printing and
delivery to the Underwriters of copies of the Registration Statement as
originally filed and of each amendment thereto, of each preliminary prospectus,

(ix) the listing fees of the New York Stock Exchange.

with the provisions of Section 5 or Section 9(a)(i) hereof, the Company shall
reimburse the Underwriters for all of their out-of-pocket expenses, including
the reasonable fees and disbursements of counsel for the Underwriters.

         SECTION 5.       CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The
obligations of the Underwriters hereunder to purchase and pay for the
Securities to be delivered at either Closing Time are subject to the accuracy
of the representations and warranties of the Company herein contained or in

hereof, to the performance by the Company of its obligations hereunder, and to
the following further conditions:

         effective not later than 5:30 P.M. on the date hereof, or with the
         consent of Merrill Lynch, at a later time and date, not later,
         however, that 5:30 P.M. on the first business day following the date
         hereof, or at such later time and date as may be approved by the
         majority in interest of the Underwriters; and at such Closing Time no
         stop order suspending the effectiveness of the Registration Statement
         shall have been issued under the 1933 Act or proceedings therefor
         initiated or threatened by the Commission.  If the Company has elected
         to rely upon Rule 430A of the 1933 Act Regulations, the price of the
         Securities and any price-related information previously omitted from
         the effective Registration Statement pursuant to such Rule 430A shall
         have been transmitted to the Commission for filing pursuant to Rule
         424(b) of the 1933 Act Regulations within the prescribed time period,
         and prior to the First Closing Time the Company shall have provided
         evidence satisfactory to the Underwriters of such timely filing, or a
         post-effective amendment providing such information shall have been
         promptly filed and declared effective in accordance with the
         requirements of Rule 430A of the 1933 Act Regulations.

         Closing Time.

                 (c)      At such Closing Time, the Representatives shall have
         received the favorable opinion of Baker & Botts, L.L.P., counsel to
         the Company, dated as of such Closing Time, to the following effect:

                 Limited Partnership Act and is validly existing as a limited

                 Commission or became effective under the 1934 Act, as the case
                 may be, appeared on the face thereof to comply, as to form in
                 all material respects with the requirements of the 1934 Act
                 and the 1934 Act Regulations (except that such counsel need
                 express no opinion as to the exhibits, financial statements,
                 schedules and other financial, reserve or statistical
                 information included or incorporated by reference in any such
                 document).

                           (x) The Purchase Agreement and the Pricing Agreement
                 have been duly authorized, executed and delivered by the 
                 Company.

                          (xi) The Securities to be issued and sold by the
                 Company under the Purchase Agreement at such Closing Time have
                 been duly authorized and will, upon payment therefor as
                 contemplated by this Agreement, be validly issued, fully paid
                 and nonassessable; and there are no preemptive or similar
                 rights with respect to such issuance of such Securities.

                          (xii) The Registration Statement has become effective
                 under the 1933 Act and, to their knowledge, no stop order
                 suspending the effectiveness of the Registration Statement has
                 been issued under the 1933 Act or proceedings therefor
                 initiated or threatened by the Commission.

                          (xiii) At the time the Registration Statement became
                 effective, the Registration Statement appeared on its face to
                 comply as to form in all material respects with the
                 requirements of the 1933 Act and the 1933 Act Regulations
                 (except that such counsel need express no opinion in this
                 paragraph (xiii) as to any documents incorporated therein by
                 reference or as to the exhibits, financial statements,
                 schedules and other financial, reserve or statistical
                 information contained in the Registration Statement or the
                 Prospectus or incorporated by reference therein).

                          (xiv) No authorization, approval or consent of any
                 court or governmental authority or agency (other than pursuant
                 to the securities or blue sky laws of the various states) is
                 required to be obtained by the Company for the sale of the
                 Securities being delivered at such Closing Time under the
                 Purchase Agreement, except for the order of the Commission
                 declaring the Registration Statement effective under the 1933
                 Act, which order has been obtained.


                 (d)      At such Closing Time, the Representatives shall have
         received the favorable opinion of Vinson & Elkins L.L.P., counsel for
         the Underwriters, dated as of such Closing Time, with respect to the
         incorporation of the Company, the validity of the Securities being
         delivered at such Closing Time, the Registration Statement, the
         Prospectus and such other related matters as the Representatives may
         require.  In giving their opinions required by subsections (c) and
         (d), respectively, of this Section 5, Baker & Botts, L.L.P. and Vinson
         & Elkins L.L.P. may rely, as to all matters governed by laws other
         than the law of the State of Texas, the federal law of the United
         States or the General Corporation Law of the State of Delaware, upon
         the opinions of other counsel satisfactory to the Representatives.
         Such counsel may also state that, insofar as such counsel's opinion
         involves factual matters, they have relied, to the extent they deem
         proper, upon certificates of officers of the Company and certificates
         of public officials.  In giving such opinions, Baker & Botts, L.L.P.
         and Vinson & Elkins L.L.P. shall each additionally state that they
         have participated in conferences with officers and other
         representatives of the Company, representatives of the independent
         public accountants for the Company, representatives of the
         Underwriters and other persons, at which conferences the contents of
         the Registration Statement and the Prospectus and related matters were
         discussed and, although such counsel are not passing upon, and do not
         assume any responsibility for, the accuracy, completeness or fairness
         of the statements contained in the Registration Statement or the
         Prospectus (except, in the case of Baker & Botts, L.L.P., as set forth
         in paragraph (vii) of subsection (c) above) and have not made any
         independent check or verification thereof, on the basis of the
         foregoing (relying as to materiality to a large extent upon officers
         and other representatives of the Company and upon the
         Representatives), no facts have come to such counsel's attention that
         lead them to believe that (A) the Registration Statement (including
         documents incorporated by reference therein), at the time it 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 (B) the Prospectus
         (including documents incorporated by reference therein), at the time
         it was issued or at such Closing Time, contained an untrue statement
         of a material fact or omitted to state a material fact necessary to
         make the statements therein, in light of the





                                      -13-
   15
         circumstances under which they were made, not misleading, except that
         such counsel need not comment on the exhibits, financial statements,
         schedules and other financial, reserve or statistical information
         included in the Registration Statement or the Prospectus.

                 (e)      At such Closing Time, there shall not have been,
         since the date hereof 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, and the Representatives shall have received a
         certificate of the President or a Vice President of the Company and
         the chief financial or chief accounting officer of the Company, dated
         as of such Closing Time, to the effect that: (i) there has been no
         such material adverse change, (ii) the representations and warranties
         in Section 1 hereof are true and correct with the same force and
         effect as though expressly made at and as of such Closing Time, (iii)
         the Company has complied with all agreements and satisfied all
         conditions on its part to be performed or satisfied at or prior to
         such Closing Time, and (iv) no stop order suspending the effectiveness
         of the Registration Statement has been issued and, to the best of each
         such officer's knowledge, no proceedings for that purpose have been
         initiated or threatened by the Commission.  As used in this Section
         5(e), the term "Prospectus" means the Prospectus in the form first
         used to confirm sales of the Securities.

                 (f)      At the time that this Agreement is executed by the
         Company, the Representatives shall have received from Arthur Andersen
         & Co. a letter, dated such date, in form and substance satisfactory to
         the Representatives, confirming that they are independent public
         accountants with respect to the Company and its subsidiaries within
         the meaning of the 1933 Act and the 1933 Act Regulations, and stating
         in effect that:

                          (i)     in their opinion, the audited consolidated
                 financial statements and the related financial statement
                 schedules included in the Registration Statement comply as to
                 form in all material respects with the applicable accounting
                 requirements of the 1933 Act and the 1933 Act Regulations;

                          (ii)    on the basis of procedures (but not an audit
                 in accordance with generally accepted auditing standards)
                 consisting of a reading of the latest available unaudited
                 interim consolidated financial statements of the Company, a
                 reading of the minutes of all meetings of the stockholders and
                 directors of the Company and its subsidiaries and the Audit
                 and Compensation Committees of the Company's Board of
                 Directors from the date of the latest audited financial
                 statements of the Company and its subsidiaries, inquiries of
                 certain officials of the Company 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 unaudited financial statements
                          included in the Registration Statement do not comply
                          as to form in all material respects with the
                          applicable accounting requirements of the 1933 Act
                          and the 1933 Act Regulations or that such unaudited
                          financial statements are not presented in conformity
                          with generally accepted accounting principles applied
                          on a basis substantially consistent with that of
                          audited financial statements referred to above,
                          except as disclosed in the notes to such unaudited
                          financial statements or as otherwise described in the
                          Registration Statement,

                                  (B)      at a specified date not more than
                          five days prior to the date of this Agreement, there
                          was any change (other than as a result of issuance of
                          Common Stock related to employee stock options) in
                          the consolidated capital stock or any increase in the
                          consolidated long-term debt of the Company and its
                          subsidiaries or any decrease in the consolidated net
                          assets or common shareholders' equity of the Company
                          and its subsidiaries, in each case as compared with
                          amounts shown in the December 31, 1993 balance sheet
                          included in the Registration Statement, except in
                          each case for changes or decreases that the
                          Registration Statement discloses have occurred or may
                          occur, or

                                  (C)      for the period from January 1, 1994
                          to a specified date not more than five days prior to
                          the date of this Agreement, there was any decrease in
                          consolidated revenues, consolidated net income or
                          consolidated net income per share, in each case as
                          compared with the comparable period in the preceding
                          year, except in each case for any decreases that the
                          Registration Statement discloses have occurred or may
                          occur; and

                          (iii)   in addition to the procedures referred to in
                 clause (ii) above, they have performed other specified
                 procedures, not constituting an audit, with respect to certain
                 amounts, percentages, numerical data and financial information
                 appearing in the Registration Statement, which have previously
                 been specified by the Representatives and which shall be
                 specified in such letter, and have compared certain of such
                 items with, and have found such items to be in agreement with,
                 the accounting and financial records of the Company and its
                 subsidiaries identified in such letter.

                 (g)      At such Closing Time, the Representatives shall have
         received from Arthur Andersen & Co. a letter, in form and substance
         satisfactory to them and dated as of such Closing Time, to the effect
         that they reaffirm the statements made in the letter furnished
         pursuant to Section 5(f), except that the specified date referred to
         shall be a date not more than five days prior to such Closing Time.

                 (h)      The Securities to be delivered hereunder at such
         Closing Time shall have been duly authorized for listing by the New
         York Stock Exchange, subject only to official notice of issuance.

                 (i)      The Company shall have furnished to the
         Representatives and counsel for the Underwriters, in form and
         substance satisfactory to the Representatives and to such counsel,
         such other documents, certificates and opinions as such counsel may
         reasonably request for the purpose of enabling such counsel to pass
         upon the matters referred to in Section 5(d) hereof and in order to
         evidence the accuracy and completeness of any of the representations,
         warranties or statements, the performance of any covenant by the
         Company theretofore to be performed, or the compliance with any of the
         conditions in this Agreement.

         If any of the conditions specified in this Section 5 shall not have
been fulfilled when and as required by this Agreement to be fulfilled, this
Agreement may be terminated by you on notice to the Company at any time at or
prior to such Closing Time, and such termination shall be without liability of
any party to any other party, except as provided in Section 4 hereof .
Notwithstanding any such termination, the provisions of Sections 6, 7 and 8
hereof shall remain in effect.

         SECTION 6. Indemnification.  (a) The Company 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 as follows:

                 (i)      against any and all loss, liability, claim, damage
         and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement (or any amendment thereto), including the
         information deemed to be a part of the Registration Statement pursuant
         to Rule 430A(b) of the 1933 Act Regulations, if applicable, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact contained in any preliminary prospectus
         or the Prospectus (or 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, any investigation or
         proceeding by any governmental agency or body, commenced or
         threatened, or any claim whatsoever, insofar as such litigation,
         investigation, proceeding or claim is based upon such untrue statement
         or omission, or any such alleged untrue statement or omission, if such
         settlement is effected with the written consent of the Company; and

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

provided, however, that (A) the foregoing indemnity agreement shall not apply
to any loss, liability, claim, damage or expense to the extent it arises 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 the Representatives expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto) and (B) such
indemnity with respect to any preliminary prospectus shall not inure to the
benefit of any Underwriter (or any person controlling such Underwriter) from
whom the person asserting such loss, liability, claim, damage or expense
purchased the Securities which are the subject thereof if such person did not
receive a copy of the Prospectus at or prior to the confirmation of the sale of
such Securities to such person in any case where such delivery is required by
the 1933 Act and the untrue statement or omission of a material fact contained
in such preliminary prospectus was corrected in the Prospectus, provided the
Company has delivered the Prospectus to the Underwriters on a timely basis to
permit the Prospectus to be sent or given.

         (b)     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





                                      -16-
   18
controls the Company within the meaning of Section 15 of the 1933 Act against
any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) 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) 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 the Representatives 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)     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
so to notify an indemnifying party shall not relieve such indemnifying party
from any liability which it may have otherwise than on account of this
indemnity agreement.  An indemnifying party may participate at its own expense
in the defense of any such action.  If it so elects within a reasonable time
after receipt of such notice, an indemnifying party, jointly with any other
parties receiving such notice, may assume the defense of such action with
counsel chosen by it and approved by the indemnified parties defendant in such
action, unless such indemnified parties reasonably object to such assumption on
the ground that there may be legal defenses available to them which are
different from or in addition to those available to such indemnifying party. If
an indemnifying party assumes the defense of such action, the indemnifying
parties shall not be liable for any fees and expenses of counsel for the
indemnified parties incurred thereafter in connection with such action.  In no
event shall any indemnifying party be liable for fees and expenses of more than
one counsel (in addition to any local counsel) separate from their own counsel
for all 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.

         SECTION 7.Contribution.  In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 hereof is for any reason held to be unenforceable by the indemnified
parties although applicable in accordance with its terms, the Company and the
Underwriters shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agreement
incurred by the Company and one or more Underwriters, as incurred, in such
proportions that the Underwriters are responsible for that portion represented
by the percentage that the underwriting discount appearing on the cover page of
the Prospectus bears to the initial public offering price appearing thereon and
the Company is responsible for the balance; provided, however, that 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,
each person, if any, who controls an Underwriter within the meaning of Section
15 of the 1933 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 within the meaning of Section 15 of the 1933 Act, shall have the same
rights to contribution as the Company.

         SECTION 8. Representations, Warranties, Agreements to Survive
Delivery.  The representations, warranties, indemnities, agreements and other
statements of the Company or its officers set forth in or made pursuant to this
Agreement will remain operative and in full force and effect regardless of any
investigation made by or on behalf of the Company or any Underwriter or
controlling person and will survive delivery of and payment for the Securities.

   19
         Section 9. Termination of Agreement.  (a) The Representatives may
terminate this Agreement, by notice to the Company at any time at or prior to a
Closing Time, (i) if there has been, since the date of this Agreement or 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) if there has occurred any material adverse
change in the financial markets, or any outbreak of hostilities or escalation
thereof or other calamity or crisis, the effect of which is such as to make it,
in the judgment of the Representatives, impracticable to market the Securities
or enforce contracts for the sale of the Securities or (iii) if trading in the
Common Stock has been suspended by the Commission or if trading generally on
the New York Stock Exchange has been suspended or materially limited, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices for securities have been required, by such exchange or by order of the
Commission, or any other governmental authority or (iv) if a banking moratorium
has been declared by federal or New York authorities.

         (b)     If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party, except
to the extent provided in Section 4 hereof.  Notwithstanding any such
termination, the provisions of Sections 6, 7 and 8 hereof shall remain in
effect.

         (c)     This Agreement may also terminate pursuant to the provisions

the Securities which it or they are obligated to purchase under this Agreement
and the Pricing Agreement (the "Defaulted Securities"), the Representatives
shall have the right, within 24 hours thereafter, to make arrangements for one
or 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:

                          (i)     if the number of Defaulted Securities does
                 not exceed 10% of the number of such Securities, the non-
                 defaulting Underwriters shall be obligated 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

                          (ii)    if the number of Defaulted Securities exceeds
                 10% of the number of such Securities, this Agreement shall
                 terminate without liability on the part of any non-defaulting
                 Underwriter.

                 (b)      No action taken pursuant to this Section shall
         relieve any defaulting Underwriter from liability in respect of its
         default.

                 (c)      In the event of any such default which does not
result in a termination of this Agreement, both the Representatives and the
Company shall have the right to postpone such Closing Time for a period not
exceeding seven days in order to effect any required changes in the
Registration Statement or Prospectus or in any other documents or arrangements.
