Ladies and Gentlemen:

          The undersigned PARKER-HANNIFIN CORPORATION, an Ohio corporation
("Company"), confirms its agreement with the several Underwriters
("Underwriters") as follows:

     1.   Description of Securities. The Company proposes to issue and sell to
the several Underwriters $225,000,000 principal amount of its 4.875% Senior
Notes Due February 15, 2013 ("Securities"), to be issued under an indenture
("Indenture"), dated as of May 3, 1996, between the Company and National City
Bank, as trustee ("Trustee").

     2.   Representations and Warranties of the Company. The Company represents
and warrants to, and agrees with, each Underwriter as of the date hereof and as
of the Closing Date (as defined in Section 3 below) (each, a "Representation
Date") that:

          (a)  The Company meets the requirements for use of Form S-3 under the
     Securities Act of 1933 (the "Act") and has prepared a registration
     statement (File No. 333-82806) with respect to the Securities, including a
     preliminary form of prospectus, in conformity with the requirements of the
     Act, the Trust Indenture Act of 1939 ("Trust Indenture Act") and the rules
     and regulations ("Rules and Regulations") of the Securities and Exchange
     Commission ("Commission") thereunder. The registration statement has been
     filed with the Commission and has become effective. No stop order
     suspending the effectiveness of the registration statement has been issued
     and no proceeding for that purpose has been instituted or threatened by the
     Commission. No amendment or supplement thereto or to any document
     incorporated by reference therein has heretofore been filed with the
     Commission. Copies of such registration statement, any such amendments and
     each related preliminary prospectus ("Preliminary Prospectus") have been
     delivered to you. A supplemental prospectus relating to the Securities has
     been or will be prepared and will be filed pursuant to Rule 424 under the
     Act. As filed, such



     registration statement as amended at the time it became effective is herein
     referred to as the "Registration Statement", and such supplemental
     prospectus (including all documents and information incorporated by
     reference therein), as the "Prospectus." Any reference herein to the
     Registration Statement, any Preliminary Prospectus or the Prospectus
     includes all documents and information incorporated by reference therein
     and any reference herein to the terms "amend," "amendment" or "supplement"
     with respect to the Registration Statement, any Preliminary Prospectus or
     the Prospectus shall be deemed to refer to and include any documents filed
     with the Commission after the date of such Registration Statement,
     Preliminary Prospectus or Prospectus, as the case may be, under the
     Securities Exchange Act of 1934 ("Exchange Act") and so incorporated by
     reference.

          (b)  No order preventing or suspending the use of any Preliminary
     Prospectus has been issued by the Commission and each Preliminary
     Prospectus, at the time of filing thereof, did 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, in the light
     of the circumstances under which they were made, not misleading, except
     that the foregoing shall not apply to statements in or omissions from any
     Preliminary Prospectus in reliance upon, and in conformity with, written
     information furnished to the Company by you specifically for use in the
     preparation thereof.

          (c)  Each part of the registration statement, when such part became
     effective, each Preliminary Prospectus, on the date of filing thereof with
     the Commission, and the Prospectus and any amendment or supplement thereto,
     on the date of filing thereof with the Commission and on the Closing Date,
     conformed or will conform in all material respects with the requirements of
     the Act, the Trust Indenture Act and the Rules and Regulations; each part
     of the registration statement, when such part became effective, did not or
     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; each Preliminary Prospectus, on the date
     of filing thereof with the Commission, and the Prospectus and any amendment
     or supplement thereto, on the date of filing thereof with the Commission
     and on the Closing Date, did not or will not include 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, in the light of the
     circumstances under which they were made, not misleading; except that the
     foregoing shall not apply to statements in or omissions from any such
     document in reliance upon, and in conformity with, written information
     furnished to the Company by you specifically for use in the preparation
     thereof.

          (d)  The documents from which information is incorporated by reference
     in the Prospectus, when they became effective or were filed with the
     Commission, as the case may be, conformed in all material respects to the
     requirements of the Act, the Exchange Act, as applicable, and the Rules and
     Regulations, and any documents so filed and incorporated by reference
     subsequent to the effective date of the Registration Statement will, when
     they are filed with the Commission, conform in all material respects to the

                                        2



     requirements of the Act and the Exchange Act, as applicable, and the Rules
     and Regulations.

          (e)  The financial statements of the Company and its subsidiaries set
     forth in the Registration Statement and Prospectus, together with the
     related schedules and notes, fairly present the financial condition of the
     Company and its subsidiaries as of the dates indicated and the results of
     operations and changes in financial position for the periods therein
     specified, in conformity with generally accepted accounting principles
     consistently applied throughout the periods involved.

          (f)  The Company and each of its subsidiaries has been duly
     incorporated and is an existing corporation in good standing under the laws
     of its jurisdiction of incorporation, has full power and authority
     (corporate and other) to conduct its business as described in the
     Registration Statement and Prospectus, and is duly qualified to do business
     in each jurisdiction in which it owns or leases real property or in which
     the conduct of its business requires such qualification except where the
     failure to be so qualified, considering all such cases in the aggregate,
     does not involve a material risk to the business, properties, financial
     position or results of operations of the Company and its subsidiaries
     (taken as a whole); and all of the outstanding shares of capital stock of
     each such subsidiary have been duly authorized and validly issued, are
     fully paid and non-assessable and (except as otherwise stated in the
     Prospectus) are owned beneficially by the Company subject to no security
     interest, mortgage, pledge, lien, other encumbrance or adverse claim.

          (g)  The Indenture and the Securities have been duly authorized, the
     Indenture has been duly qualified under the Trust Indenture Act, executed
     and delivered and constitutes, and the Securities, when duly executed,
     authenticated, issued and delivered as contemplated hereby and by the
     Indenture, will constitute valid and legally binding obligations of the
     Company enforceable in accordance with their terms subject, as to
     enforcement, to bankruptcy, insolvency, reorganization and other laws of
     general applicability relating to or affecting creditors' rights and to
     general equity principles. The Securities will be in the form contemplated
     by, and each registered holder thereof will be entitled to the benefits of,
     the Indenture.

          (h)  This agreement has been duly authorized, executed and delivered
     by the Company.

          (i)  Except as contemplated in the Prospectus, subsequent to the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, neither the Company nor any of its
     subsidiaries has incurred any liabilities or obligations, direct or
     contingent, or entered into any transactions, not in the ordinary course of
     business, that are material to the Company and its subsidiaries (taken as a
     whole), and there has not been any material change, on a consolidated
     basis, in the capital stock, short-term debt or long-term debt of the
     Company and its subsidiaries, or any material adverse change, or any
     development involving a prospective material adverse change, in

                                        3



     the condition (financial or other), business, prospects, net worth or
     results of operations of the Company and its subsidiaries (taken as a
     whole).

          (j)  Except as set forth in the Prospectus, there is not pending or,
     to the knowledge of the Company, threatened, any action, suit or proceeding
     to which the Company or any of its subsidiaries is a party before or by any
     court or governmental agency or body, which might result in any material
     adverse change in the condition (financial or other), business, prospects,
     net worth or results of operations of the Company and its subsidiaries, or
     might materially and adversely affect the properties or assets thereof or
     the consummation of the transactions contemplated in the Indenture and this
     Agreement or the performance by the Company of its obligations under the
     Indenture and this Agreement.

          (k)  There are no contracts or documents of the Company or any of its
     subsidiaries that are required to be filed as exhibits to the Registration
     Statement by the Act or by the Rules and Regulations that have not been so
     filed.

          (l)  The statements in the Prospectus under the captions "Description
     of the Notes" and "Underwriting", insofar as they purport to constitute a
     summary of the terms of the Securities, this Agreement or the Indenture,
     are accurate, complete and fair. This Agreement will be incorporated by
     reference as an exhibit to the Registration Statement.

          (m)  Except for such breaches, defaults and violations which in the
     aggregate do not materially and adversely affect the business, properties,
     financial position or results of operations of the Company and its
     subsidiaries (taken as a whole) or which do not materially and adversely
     affect the consummation of the transactions contemplated in the Indenture
     and this Agreement or the performance by the Company of its obligations
     under the Indenture and this Agreement, the performance of this Agreement
     and the consummation of the transactions herein contemplated will not
     result in a breach or violation of any of the terms and provisions of, or
     constitute a default under (i) any agreement or instrument to which the
     Company or its subsidiaries is a party or by which it or any of them may be
     bound or to which any of the property of the Company or its subsidiaries is
     subject; (ii) the charter or bylaws or other constitutive documents of the
     Company or its subsidiaries; or (iii) any order, statute, law, rule or
     regulation of any court or governmental agency or body having jurisdiction
     over the Company or its subsidiaries or any of their respective properties.
     No consent, approval, authorization or order of, or filing with, any court
     or governmental agency or body is required for the consummation of the
     transactions contemplated by the Indenture and this Agreement, in
     connection with the issuance or sale of the Securities by the Company,
     except such as may be required under the Act, the Trust Indenture Act or
     state securities laws and the Company has full power and authority to
     authorize, issue and sell the Securities as contemplated by this Agreement.

     3.   Purchase, Sale and Delivery of Securities. On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set

                                        4

a purchase price of 98.615% of the principal amount of the Securities, plus
accrued interest from February 10, 2003, the amount of Securities set forth

order of the Company, at the office of Sullivan & Cromwell, 125 Broad Street,
New York, New York, at 10:00 A.M., New York City time, February 10, 2003 (or if

thereafter as you and the Company determine, such time being herein referred to

     4.   Covenants. The Company covenants and agrees with each Underwriter
that:

          (a)  The Company will use its best efforts to cause any amendments to
     the Registration Statement to become effective as promptly as possible; it
     will notify you promptly of the time when any such amendment to the
     Registration Statement has become effective or any supplement to the
     Prospectus has been filed and of any request by the Commission for any
     amendment or supplement to the Registration Statement or Prospectus or for
     additional information; it will prepare and file with the Commission,
     promptly upon your request, any amendments or supplements to the
     Registration Statement or Prospectus that, in your opinion, may be
     necessary or advisable in connection with the distribution of the
     Securities by the Underwriters; and it will file no amendment or supplement
     to the Registration Statement or Prospectus (other than any document
     required to be filed under the Exchange Act that upon filing is deemed to
     be incorporated by reference therein) to which you shall reasonably object
     by notice to the Company after having been furnished a copy a reasonable
     time prior to the filing, and it will furnish to you at or prior to the
     filing thereof a copy of any document that upon filing is deemed to be
     incorporated by reference in whole or in part in the Prospectus.

          (b)  The Company will advise you, promptly after it shall receive
     notice or obtain knowledge thereof, of (i) the issuance by the Commission
     of any stop order suspending the effectiveness of the Registration
     Statement, (ii) the suspension of the qualification of the Securities for
     offering or sale in any jurisdiction, or (iii) the initiation or
     threatening of any proceeding for any such purpose. The Company will
     promptly use its best efforts to prevent the issuance of any stop order or
     to obtain its withdrawal if such a stop order should be issued.

                                        5



          (c)  Within the time during which a prospectus relating to the
     Securities is required to be delivered under the Act, the Company will use
     its best efforts to comply with all requirements imposed upon it by the
     Act, as now and hereafter amended, and by the Rules and Regulations, as
     from time to time in force, so far as necessary to permit the continuance
     of sales of or dealings in the Securities as contemplated by the provisions
     hereof and the Prospectus. If during such period any event occurs as a
     result of which the Prospectus as then amended or supplemented would
     include an untrue statement of a material fact or omit to state a material
     fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, or if during such
     period it is necessary to amend the Registration Statement or supplement
     the Prospectus to comply with the Act, the Exchange Act or the Rules and
     Regulations, the Company will (i) promptly notify you, (ii) will prepare
     and file with the Commission, subject to the first sentence of paragraph
     (a) of this Section 4 an amendment or supplement to the Registration
     Statement or Prospectus (at the expense of the Company) so as to correct
     such statement or omission or effect such compliance and (iii) supply any
     supplement to the Prospectus to you in such quantities as you may
     reasonably request.

          (d)  The Company will use its best efforts to qualify the Securities
     for sale under the securities law of such jurisdictions as you reasonably
     designate and to continue such qualifications in effect so long as required
     for the distribution of the Securities, except that the Company shall not
     be required in connection therewith to qualify as a foreign corporation
     where it is not now so qualified or to execute a general consent to service
     of process in any state where it is not now so subject. The Company will
     also arrange for the determination of the eligibility for investment of the
     Securities under the laws of such jurisdictions as you reasonably request.

          (e)  The Company will furnish to the Underwriters copies of the
     Registration Statement (three of which will include all exhibits), each
     Preliminary Prospectus, the Prospectus (including all documents from which
     information is incorporated by reference), and all amendments and
     supplements to such documents, in each case as soon as available and in
     such quantities as you may from time to time reasonably request.

          (f)  The Company will make generally available to its security holders
     as soon as practicable, but in any event not later than 15 months after the
     end of the Company's current fiscal quarter, an earnings statement (which
     need not be audited) covering a 12-month period beginning after the date
     upon which the Prospectus is filed pursuant to Rule 424 under the Act that
     shall satisfy the provisions of Section 11(a) of the Act.

          (g)  The Company, whether or not the transactions contemplated
     hereunder are consummated or this Agreement is terminated, will pay all
     expenses incident to the performance of its obligations hereunder, will pay
     the expenses of printing all documents relating to the offering, and will
     reimburse the Underwriters for any expenses (including fees and
     disbursements of counsel) incurred by them in connection with the matters
     referred to in Section 4(d) hereof and the preparation of memoranda
     relating thereto and for any fees charged by investment rating agencies for
     rating the Securities. If the sale of

                                        6



     the Securities provided for herein is not consummated by reason of any
     failure, refusal or inability on the part of the Company to perform any
     agreement on its part to be performed, or because any other condition of
     the Underwriters' obligations hereunder required to be fulfilled by the
     Company is not fulfilled, the Company will reimburse the several
     Underwriters for all reasonable out-of-pocket disbursements (including fees
     and disbursements of counsel) incurred by the Underwriters in connection
     with their investigation, preparing to market and marketing the Securities
     or in contemplation of performing their obligations hereunder. The Company
     shall not in any event be liable to any of the Underwriters for loss of
     anticipated profits from the transactions covered by this Agreement.

          (h)  The Company will apply the net proceeds from the sale of the
     Securities to be sold by it hereunder for the purposes set forth in the
     Prospectus.

          (i)  During the period beginning from the date hereof and continuing
     to and including the Closing Date, the Company will not, without the prior
     written consent of Banc of America Securities, LLC, offer, sell, contract
     to sell, pledge, or otherwise dispose of, (or enter into any transaction
     which is designed to, or might reasonably be expected to, result in the
     disposition (whether by actual disposition or effective economic
     disposition due to cash settlement or otherwise) by the Company or any
     affiliate of the Company or any person in privity with the Company or any
     affiliate of the Company) directly or indirectly, including the filing (or
     participation in the filing) of a registration statement with the
     Commission in respect of, or establish or increase a put equivalent
     position or liquidate or decrease a call equivalent position within the
     meaning of Section 16 of the Exchange Act, any debt securities issued or
     guaranteed by the Company (other than the Securities) or publicly announce
     an intention to effect any such transaction.

     5.   Conditions of Underwriters' Obligations. The obligations of the
several Underwriters to purchase and pay for the Securities, as provided herein,
shall be subject to the accuracy, as of the date hereof and the Closing Date (as
if made at the Closing Date), of the representations and warranties of the
Company herein, to the performance by the Company of its obligations hereunder
and to the following additional conditions:

          (a)  If filing of the Prospectus, or any supplement thereto, is
     required pursuant to Rule 424(b), the Prospectus, and any such supplement,
     will be filed in the manner and within the time period required by Rule
     424(b); and no stop order suspending the effectiveness of the Registration
     Statement shall have been issued and no proceeding for that purpose shall
     have been instituted or, to the knowledge of the Company or any
     Underwriter, threatened by the Commission, and any request of the
     Commission for additional information (to be included in the Registration
     Statement or the Prospectus or otherwise) shall have been complied with to
     your satisfaction.

          (b)  No Underwriter shall have advised the Company that the
     Registration Statement or Prospectus, or any amendment or supplement
     thereto, contains an untrue statement of fact which in your opinion is
     material, or omits to state a fact which in your

                                        7



     opinion is material and is required to be stated therein or is necessary to
     make the statements therein (in the case of the Prospectus, in the light of
     the circumstances under which they were made) not misleading.

          (c)  Except as contemplated in the Prospectus, subsequent to the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, (i) neither the Company nor any of its
     subsidiaries has incurred any liabilities or obligations, direct or
     contingent, or entered into any transactions, not in the ordinary course of
     business and (ii) there shall not have been any change, on a consolidated
     basis, in the capital stock, short-term debt or long-term debt of the
     Company and its subsidiaries, or any change, or any development involving a
     prospective change, in the condition (financial or other), business,
     prospects, net worth or results of operations of the Company and its
     subsidiaries (taken as a whole), that, in each case in your judgment, is so
     material and adverse as to make it impractical or inadvisable to offer or
     deliver the Securities on the terms and in the manner contemplated in the
     Prospectus.

          (d)  You shall have received the opinion of Jones, Day, Reavis &
     Pogue, counsel for the Company, dated the Closing Date, in substantially
     the form attached as Exhibit I hereto.

          (e)  You shall have received the opinion of Thomas A. Piraino, Jr.,

     the Closing Date, covering the matters in the paragraph numbered (4) on
     Exhibit I and to the effect that:

          to do business in each state in which it owns or leases real property,
          except where the failure to be so qualified, considering all such
          cases in the aggregate, does not involve a material risk to the
          business, properties, financial position or results of operations of
          the Company and its subsidiaries (taken as a whole).

               (ii) each "significant subsidiary" of the Company (as such term
          is defined in Rule 1-01 of Regulation S-X) organized under the laws of

          described in the Prospectus and is qualified to do business in each
          state in which it owns or leases real property, except where the
          failure to be so qualified, considering all such cases in the
          aggregate, does not involve a material risk to the business,
          properties, financial position or results of the operations of the
          Company and its Domestic Subsidiaries (taken as a whole); all of the
          outstanding shares of capital stock of each of the Domestic

          of the outstanding shares of capital stock of each of the Significant
          Foreign Subsidiaries have been duly authorized and validly issued, are
          fully paid and non-assessable and (except for shareholders' or
          directors' qualifying shares) are owned, directly or indirectly, by
          the Company subject to no security interest, other encumbrance, or
          adverse claim (such counsel being entitled to rely upon opinions of
          local counsel, provided that such counsel shall furnish to you signed
          copies thereof and state that he believes that both you and he are
          justified in relying upon such opinion); and

               (iv)  Neither the execution and delivery of this agreement nor
          the performance of the transactions herein contemplated will result in
          the violation of any statute or regulation or any order or decree of
          any court or governmental authority known to the Company which is
          binding upon the Company or its property, or conflict with or result
          in a default under any of the terms and provisions of the Company's
          Amended Articles of Incorporation or Code of Regulations or any
          indenture, loan agreement or any agreement to which the Company is a
          party or by which it is bound listed on an exhibit to such opinion and
          attached thereto.

          (f)  You shall have received from Sullivan & Cromwell, counsel for the
     several Underwriters, such opinion or opinions, dated the Closing Date,
     with respect to the incorporation of the Company, the validity of the
     Securities, the Registration Statement, the Prospectus and other related
     matters as you reasonably may request, and such counsel shall have received
     such papers and information as they request to enable them to pass upon
     such matters. In rendering their opinion, such counsel may rely upon the
     opinion of Jones, Day, Reavis & Pogue referred to above as to all matters
     governed by Ohio law.

          (g)  On the Closing Date, you shall have received a letter from
     Pricewaterhouse Coopers, dated the date of delivery thereof, to the effect
     set forth in Exhibit II hereto.

                                        9



          (h)  You shall have received from the Company a certificate, signed by
     the Chairman of the Board, the President or a Vice President and by the
     principal financial or accounting officer, dated the Closing Date, to the
     effect that, to the best of their knowledge based upon reasonable
     investigation:

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

               (ii)  No stop order suspending the effectiveness of the
          Registration Statement has been issued, and no proceeding for that
          purpose has been instituted or is threatened by the Commission; and

               (iii) Since the effective date of the Registration Statement,
          there has occurred no event required to be set forth in an amendment
          or supplement to the Registration Statement or Prospectus that has not
          been so set forth and there has been no document required to be filed
          under the Exchange Act and the rules and regulations thereunder that
          upon such filing would be deemed to be incorporated by reference in
          the Prospectus that has not been so filed.

          (i)  The Company shall have furnished to you such further certificates
     and documents as you shall have reasonably requested.

All such opinions, certificates, letters and other documents will be in
compliance with the provisions hereof only if they are satisfactory in form and
substance to you. The Company will furnish you with such conformed copies of
such opinions, certificates, letters and other documents as you shall reasonably
request.

     6.   Indemnification and Contribution. (a) The Company agrees to indemnify
and hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Act or Section 20 of
the Exchange Act from and against any and all losses, claims, damages and
liabilities, (including, without limitation, any legal or other expenses
reasonably incurred by any Underwriter or any such controlling person in
connection with defending or investigating any such action or claim) based upon,
arising out of or caused by any untrue statement or alleged untrue statement of
a material fact contained in the Registration Statement or any amendment
thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or based upon, arising out of or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to any Underwriter furnished to the Company in writing by such
Underwriter through you expressly for use therein. This indemnity agreement will
be in addition to any liability which the Company may otherwise have.

                                       10



          (b) Each Underwriter agrees, severally and not jointly, to indemnify
     and hold harmless the Company, its directors, its officers who sign the
     Registration Statement and each person, if any, who controls the Company
     within the meaning of either Section 15 of the Act or Section 20 of the
     Exchange Act to the same extent as the foregoing indemnity from the Company
     to such Underwriter, but only with reference to information relating to
     such Underwriter furnished to the Company in writing by such Underwriter
     through you expressly for use in the Registration Statement, any
     preliminary prospectus, the Prospectus or any amendments or supplements
     thereto. This indemnity agreement will be in addition to any liability
     which any Underwriter may otherwise have.

          (c) In case any proceeding (including any governmental investigation)
     shall be instituted involving any person in respect of which indemnity may
     be sought pursuant to either paragraph (a) or (b) of this Section 6, such
     person (the "indemnified party") shall promptly notify the person against
     whom such indemnity may be sought (the "indemnifying party") in writing and
     the indemnifying party, upon request of the indemnified party, shall retain
     counsel reasonably satisfactory to the indemnified party to represent the
     indemnified party and any others the indemnifying party may designate in
     such proceeding and shall pay the fees and disbursements of such counsel
     related to such proceeding. In any such proceeding, any indemnified party
     shall have the right to retain its own counsel, but the fees and expenses
     of such counsel shall be at the expense of such indemnified party unless
     (i) the indemnifying party and the indemnified party shall have mutually
     agreed to the retention of such counsel or (ii) the named parties to any
     such proceeding (including any impleaded parties) include both the
     indemnifying party and the indemnified party and representation of both
     parties by the same counsel would be inappropriate due to actual or
     potential differing interests between them. It is understood that the
     indemnifying party shall not, in respect of the legal expenses of any
     indemnified party in connection with any proceeding or related proceedings
     in the same jurisdiction, be liable for the fees and expenses of more than
     one separate firm (in addition to any local counsel) for all such
     indemnified parties and that all such fees and expenses shall be reimbursed
     as they are incurred. Such firm shall be designated in writing by Banc of
     America Securities LLC, in the case of parties indemnified pursuant to
     paragraph (a) above and by the Company, in the case of parties indemnified
     pursuant to paragraph (b) above. The indemnifying party shall not be liable
     for any settlement of any proceeding effected without its written consent,
     but if settled with such consent or if there be a final judgment for the
     plaintiff, the indemnifying party agrees to indemnify the indemnified party
     from and against any loss or liability by reason of such settlement or
     judgment. Notwithstanding the foregoing sentence, if at any time an
     indemnified party shall have requested an indemnifying party to reimburse
     the indemnified party for fees and expenses of counsel as contemplated by
     the second and third sentences of this paragraph, the indemnifying party
     agrees that it shall be liable for any settlement of any proceeding
     effected without its written consent if (i) such settlement is entered into
     more than 30 days after receipt by such indemnifying party of the aforesaid
     request and (ii) such indemnifying party shall not have reimbursed the
     indemnified party in accordance with such request prior to the date of such
     settlement. No indemnifying party shall, without the prior written consent
     of the indemnified party, effect any settlement of or consent to

                                       11



     the entry of any judgment with respect to any pending or threatened
     proceeding in respect of which any indemnified party is or could have been
     a party and indemnity could have been sought hereunder by such indemnified
     party, unless (i) such settlement includes an unconditional release of such
     indemnified party from all liability on claims that are the subject matter
     of such proceeding and (ii) does not include a statement as to an admission
     of fault, culpability or a failure to act, by or on behalf of any
     indemnified party.

          (d) To the extent the indemnification provided for in paragraph (a) or
     (b) of this Section 6 is unavailable to an indemnified party or
     insufficient in respect of any losses, claims, damages or liabilities
     referred to therein, then each indemnifying party under such paragraph, in
     lieu of indemnifying such indemnified party thereunder, shall contribute to
     the amount paid or payable by such indemnified party as a result of such
     losses, claims, damages or liabilities (i) in such proportion as is
     appropriate to reflect the relative benefits received by the Company on the
     one hand and the Underwriters on the other hand from the offering of the
     Securities or (ii) if the allocation provided by clause (i) above is not
     permitted by applicable law, in such proportion as is appropriate to
     reflect not only the relative benefits referred to in clause (i) above but
     also the relative fault of the Company on the one hand and of the
     Underwriters on the other hand in connection with the statements or
     omissions that resulted in such losses, claims, damages or liabilities, as
     well as any other relevant equitable considerations. The relative benefits
     received by the Company on the one hand and the Underwriters on the other
     hand in connection with the offering of the Securities shall be deemed to
     be in the same respective proportions as the net proceeds from the offering
     of the Securities (before deducting expenses) received by the Company and
     the total underwriting discounts and commissions received by the
     Underwriters, in each case as set forth in the table on the cover of the
     Prospectus, bear to the aggregate Public Offering Price of the Securities.
     The relative fault of the Company on the one hand and the Underwriters on
     the other hand shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or the
     omission or alleged omission to state a material fact relates to
     information supplied by the Company or by the Underwriters and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such statement or omission. The Underwriters' respective
     obligations to contribute pursuant to this Section 6 are several in
     proportion to the respective principal amounts of Securities they have
     purchased hereunder, and not joint.

          (e) The Company and the Underwriters agree that it would not be just
     or equitable if contribution pursuant to this Section 6 were determined by
     pro rata allocation (even if the Underwriters were treated as one entity
     for such purpose) or by any other method of allocation that does not take
     account of the equitable considerations referred to in paragraph (d) of
     this Section 6. The amount paid or payable by an indemnified party as a
     result of the losses, claims, damages and liabilities referred to in the
     immediately preceding paragraph shall be deemed to include, subject to the
     limitations set forth above, any legal or other expenses reasonably
     incurred by such indemnified party in connection with investigating or
     defending any such action or claim. Notwithstanding the provisions of this
     Section 6, no Underwriter shall be required to contribute any amount in
     excess of

                                       12



     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 that such Underwriter has otherwise been required to
     pay by reason of such untrue or alleged untrue statement or omission or
     alleged omission. No person guilty of fraudulent misrepresentation (within
     the meaning of Section 11(f) of the Act) shall be entitled to contribution
     from any person who was not guilty of such fraudulent misrepresentation.
     The remedies provided for in this Section 6 are not exclusive and shall not
     limit any rights or remedies which may otherwise be available to any
     indemnified party at law or in equity.

     7.   Representations and Agreements to Survive Delivery. All
representations, warranties, and agreements of the Company herein or in
certificates delivered pursuant hereto, and the agreements of the several
Underwriters contained in Section 6 hereof, shall remain operative and in full
force and effect regardless of any termination of this Agreement, any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, or the Company or any of its officers, directors or any person
controlling the Company, and shall survive delivery of the Securities to the
Underwriters hereunder.

     8.   Substitution of Underwriters. (a) If any Underwriter or Underwriters
shall fail to take up and pay for the amount of Securities agreed by such
Underwriter or Underwriters to be purchased hereunder, upon tender of such
Securities in accordance with the terms hereof, and the amount of Securities not
purchased does not aggregate more than 10% of the total amount of Securities set
forth in Schedule A hereto, the remaining Underwriters shall be obligated to
take up and pay for (in proportion to their respective underwriting obligations
hereunder as set forth in Schedule A hereto except as may otherwise be
determined by you) the Securities that the withdrawing or defaulting
Underwriters agreed but failed to purchase.

          (b) If any Underwriter or Underwriters shall fail to take up and pay
     for the amount of Securities agreed by such Underwriter or Underwriters to
     be purchased hereunder, upon tender of such Securities in accordance with
     the terms hereof, and the amount of Securities not purchased aggregates
     more than 10% of the total amount of Securities set forth in Schedule A
     hereto, and arrangements satisfactory to you and the Company for the
     purchase of such Securities by other persons are not made within 36 hours
     thereafter, this Agreement shall terminate. In the event of any such
     termination the Company shall not be under any liability to any Underwriter
     (except to the extent provided in Section 4(g) and Section 6 hereof) nor
     shall any Underwriter (other than an Underwriter who shall have failed,
     otherwise than for some reason permitted under this Agreement, to purchase
     the amount of Securities agreed by such Underwriter to be purchased
     hereunder) be under any liability to the Company (except to the extent
     provided in Section 6 hereof).

     9.  Termination. You shall have the right to terminate this Agreement by
giving notice as hereinafter specified at any time at or prior to the Closing
Date if (i) the Company shall have failed, refused or been unable, at or prior
to the Closing Date, to perform any agreement on its part to be performed
hereunder, (ii) any other condition of the Underwriters' obligations

                                       13



hereunder is not fulfilled, (iii) a suspension or material limitation in trading
in securities generally on the New York Stock Exchange or the American Stock
Exchange shall have occurred; (iv) a suspension or material limitation in
trading the Company's securities on the New York Stock Exchange shall have
occurred; (v) a general moratorium on commercial banking activities shall have
been declared by either Federal or New York State authorities or a material
disruption in commercial banking or securities settlement or clearance services
in the United States shall have occurred; (vi) any downgrading shall have
occurred in the rating accorded the Company's debt securities by any "nationally
recognized statistical rating organization," as that term is defined by the
Commission for purposes of Rule 436(g)(2) under the Act or any such organization
shall have publicly announced that it has under surveillance or review, with
possible negative implications, its rating of any of the Company's debt
securities; (vii) the outbreak or escalation of hostilities involving the United
States or the declaration by the United States of a national emergency or war
shall have occurred or (viii) the occurrence of any other calamity or crisis or
any change in financial, political or economic conditions in the United States
or elsewhere, if the effect of any such event specified in clause (vii) or
(viii) in your judgment makes it impracticable or inadvisable to proceed with
the public offering or the delivery of the Securities on the terms and in the
manner contemplated in the Prospectus. Any such termination shall be without
liability of any party to any other party except that the provisions of Section
4(g) and Section 6 hereof shall at all times be effective. If you elect to
prevent this Agreement from becoming effective or to terminate this Agreement as
provided in this Section, the Company shall be notified promptly by you by
telephone or telegram, confirmed by letter.

     10. Notices. All notices or communications hereunder, except as herein
otherwise specifically provided, shall be in writing and if sent to you shall be

LLC, Transaction Management (fax no. (704) 388-9459) and confirmed to Banc of
America Securities LLC at 100 North Tryon Street, Charlotte, North Carolina,

questionnaire or other notice furnished to the Company in writing for the
purpose of communications hereunder. Any party to this Agreement may change such
address for notices by sending to the parties to this Agreement written notice
of a new address for such purpose.

     11. Parties. This Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and the controlling
persons, officers and directors referred to in Section 6, and no other person
will have any right or obligation hereunder.

     12. Applicable Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York.

     13. Counterparts. This Agreement may be signed in two or more counterparts,
each of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument.

     (1)  The Indenture has been duly authorized, executed and delivered by the
Company and duly qualified under the Trust Indenture Act of 1939 and is a valid
and binding instrument of the Company, enforceable against the Company in
accordance with its terms, subject to the effect of (i) general principles of
equity, regardless of whether such enforceability is considered in a proceeding
in equity or at law, and (ii) any applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights
generally.

     (2)  The Securities have been duly authorized and, when executed and
authenticated in accordance with the provisions of the Indenture and delivered
to and paid for by the purchasers thereof on the date of such opinion, will be
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms, subject to the effect of (i) general principles of
equity, regardless of whether such enforceability is considered in a proceeding
in equity or at law, and (ii) any applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights
generally.

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

     (4)  Neither the execution and delivery of the Underwriting Agreement nor
the performance of the transactions therein contemplated will result in the
violation of any statute or regulation or any order or decree of any court or
governmental authority known to us which is binding upon the Company or its
property, or conflict with or result in a default under any of the terms and
provisions of the Company's Amended Articles of Incorporation or Code of
Regulations or any indenture, loan agreement or any agreement listed on Exhibit
A attached hereto.

     (5)  No consent, approval, authorization or order of any governmental
agency or body is required for the issuance or sale by the Company of the
Securities, except such as have been obtained under the Act and the Trust
Indenture Act and such as may be required under state securities or Blue Sky
laws in connection with the purchase and distribution of the Securities by the
Underwriters.

          We have participated in the preparation of the Registration Statement
and Prospectus (certain of the documents incorporated into the Prospectus by
reference having previously been prepared and filed by the Company without our
participation). From time to time we have had discussions with officers and
employees of the Company, accountants and auditors, the independent accountants
who examined certain of the financial statements of the Company and its
consolidated subsidiaries included in the Registration Statement and Prospectus,
and your representatives concerning the information contained in the
Registration Statement and Prospectus and the proposed responses to various
items in Form S-3. Based thereupon we are of the opinion that the Registration
Statement and the Prospectus (except for financial statements, financial
schedules, and other financial data included therein, as to which we express no
opinion) at the time the Registration Statement became effective under the Act

                                       18



complied as to form in all material respects with the Act and the Trust
Indenture Act and the respective rules and regulations thereunder, and that the
documents incorporated or deemed to be incorporated by reference into the
Prospectus that were filed prior to the date of this opinion (except for
financial statements, financial schedules, and other financial data included
therein, as to which we express no opinion) at the time they were filed complied
as to form in all material respects with the requirements of the Exchange Act
and the rules and regulations thereunder.

               We do not know of any litigation or governmental proceedings
required to be described in the Prospectus that are not described as required,
or of any contracts or other documents of a character required to be described
in the Registration Statement or Prospectus or to be filed as exhibits to the
Registration Statement which are not described and filed as required. The
descriptions in the Registration Statement and Prospectus of statutes, legal and
governmental proceedings, contracts and other documents present fair summaries
of such statutes, legal and governmental proceedings, contracts or other
documents. We further are of the opinion that the statements contained in the
Prospectus under the caption "Description of the Notes" and "Certain United
States Federal Income Tax Considerations," insofar as they purport to summarize
the provisions of documents or the United States Federal tax laws described
therein, present fair summaries of such provisions or such United States Federal
tax laws in effect as of the date of the Prospectus.

               The Registration Statement has become effective under the Act,
and to the best of our knowledge, no stop order suspending the effectiveness of
the Registration Statement has been issued and no proceeding for that purpose or
challenging the accuracy of any document incorporated by reference into the
Prospectus are pending or, to the best of our knowledge, threatened by the
Commission.

               We have not independently verified and are not passing upon, and
do not assume any responsibility for, the accuracy, completeness or fairness
(except as set forth in the second preceding paragraph above) of the information
contained in the Registration Statement and Prospectus, including any document
incorporated or deemed to be incorporated therein by reference. Based upon the
participation and discussions described above, however, no facts have come to
our attention that cause us to believe that the Registration Statement (except
for financial statements, financial schedules, and other financial data included
therein), at the time it became effective contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein not misleading, or that the
Prospectus (with the foregoing exceptions), on the date of the Prospectus
contained or on the Closing Date contains any untrue statement of a material
fact or omitted or omits to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

                                                                      EXHIBIT II

     (1)  They are independent certified public accountants with respect to the
Company and its subsidiaries within the meaning of the Act and the Rules and
Regulations and the answer to Item 10 of the Registration Statement form is
correct insofar as it relates to them.

     (2)  In their opinion, the financial statements and schedules examined by
them and included or incorporated by reference in the Registration Statement and
Prospectus comply as to form in all material respects with the applicable
accounting requirements of the Act or the Exchange Act, as applicable, and the
published rules and regulations thereunder.

     (3)  On the basis of procedures referred to in such letter, including a
reading of the latest available interim financial statements of the Company and
inquiries of officials of the Company responsible for financial and accounting
matters, nothing caused them to believe that:

          (A) any unaudited financial statements included or incorporated in the
     Prospectus do not comply as to form in all material respects with the
     applicable accounting requirements of the Exchange Act and the published
     rules and regulations thereunder or are not stated on a basis substantially
     consistent with that of the audited financial statements included in the
     Company's most recent Annual Report on Form 10-K; or

          (B) at a specified date not more than five days prior to the date of
     such letter, there was any change in the capital stock, short-term debt or
     long-term debt of the Company and its subsidiaries or any decrease in
     consolidated net current assets or net assets as compared with amounts
     shown in the most recent unaudited balance sheet included or incorporated
     by reference in the Prospectus, except in all cases for changes or
     decreases which the Prospectus discloses have occurred or may occur or as
     may be set forth in such letter; or

          (C) for the period from the date of the most recent unaudited balance
     sheet included or incorporated by reference in the Prospectus to a
     subsequent specified date not more than five days prior to the date of such
     letter, there was any decrease, as compared with the corresponding period
     of the previous year and with the period of corresponding length ended the
     date of such unaudited balance sheet, in consolidated net sales,
     consolidated net income before taxes, or net income, except in all cases
     for changes or decreases which the Prospectus discloses have occurred or
     may occur or as may be set forth in such letter.

     (4)  In addition to their examination referred to in their report included
or incorporated by reference in the Registration Statement and Prospectus and
the procedures referred to in (3) above, they have carried out certain other
specified procedures, not constituting an audit, with respect to certain of the
dollar amounts, percentages and other financial information to be agreed upon by
the Company and the Underwriters (in each case to the extent that such dollar
amounts, percentages and other financial information, are derived directly or by
analysis or computation, from the general accounting records of the Company and
its subsidiaries) that are included or

                                       20



incorporated by reference in the Prospectus and appear or are incorporated by
reference in the Company's Annual Report on Form 10-K under the captions "Item
1. - Business", "Item 6. - Selected Financial Data", and "Item 7. - Management's
Discussion and Analysis of Financial Condition and Results of Operations", and
have found such dollar amounts, percentages and financial information to be in
agreement with the general accounting records of the Company and its
subsidiaries.
