                           PARKER-HANNIFIN CORPORATION

     Parker is a leading worldwide full-line manufacturer of motion control
products, including fluid power systems, electromechanical controls and related
components. Fluid power involves the transfer and control of power through the
medium of liquid, gas or air, in hydraulic, pneumatic and vacuum applications.
Fluid power systems move and position materials, control machines, vehicles and
equipment and improve industrial efficiency and productivity. Components of a
simple fluid power system include a pump or compressor which generates pressure,
valves which control the fluid's flow, an actuator which translates the pressure
in the fluid into mechanical energy, a filter to insure proper fluid condition
and numerous hoses, couplings, fittings and seals. Electromechanical control
involves the use of electronic components and systems to control motion and
precisely locate or vary speed in automation applications. In addition to motion
control products, we also are a leading worldwide producer of fluid
purification, fluid flow, process instrumentation, air conditioning,
refrigeration, and electromagnetic shielding and thermal management products and
we design and manufacture custom-engineered buildings. Also, through Wynn Oil
Company and its subsidiaries, we develop, manufacture and market specialty
chemical products and automotive service equipment and market vehicle service
contracts and product warranty programs.

     Our manufacturing, service, distribution and administrative facilities are
located in 38 states, Puerto Rico and worldwide in 44 foreign countries. Our
motion control technology is used in products of our two principal business
segments, Industrial and Aerospace, and also in our third segment, Other. The
products are sold as original and replacement equipment through product and
distribution centers worldwide. We market our products through our direct-sales
employees, independent distributors, sale representatives and builder/dealers.
Our products are supplied to over 425,000 customers in virtually every
significant manufacturing, transportation and processing industry.

     Parker was incorporated in Ohio in 1938. Its principal executive offices
are located at 6035 Parkland Boulevard, Cleveland, Ohio 44124-4141, telephone
(216) 896-3000.

                                  RISK FACTORS

Any further downturn in the general economy could adversely affect our earnings
and results of operations further.

     Our ability to be profitable depends in part on the varying conditions in
the markets we serve, including the industrial and aerospace markets. These
markets move in response to the overall business environment and demand for our
products depends on general economic conditions. As a result, we have
experienced, and in the future we expect to experience, fluctuations in our net
sales and net income as general economic conditions have fluctuated. For
example, the downturn in the general economy in fiscal 2002 adversely affected
our business and results of operations as net sales (without giving effect to
acquisitions or the inclusion of businesses previously classified as assets held
for sale) decreased 12.4% for the first nine months of fiscal 2002 as compared
to the prior year period, and net income decreased 51.3% for the first nine
months of fiscal 2002 as compared to the prior year period. Over the past two
fiscal years, the downturn in general economic conditions has negatively
impacted our sales, which has resulted in an underabsorbtion of fixed costs and
consequently lower operating margins. In addition, as the general economy has
worsened, our product mix in certain markets has shifted to lower margin
products. Consequently, if there is further degradation in the general economy,
or in the industries that we sell our products and services, our business,
results of operations and financial condition would be adversely affected.





We may face limitations on our ability to complete acquisitions or successfully
integrate acquired businesses.

     We expect to continue our strategy of identifying and acquiring businesses
with complementary products and services that we believe will enhance our
operations and profitability. However, we cannot give any assurance that we will
be able to continue to find suitable businesses to purchase or that we will be
able to acquire such businesses on acceptable terms.

     In addition, we cannot guarantee that we will be able to successfully
integrate any business that we purchase into our existing business or that any
acquired businesses will be profitable. The successful integration of new
businesses depends on our ability to manage these new businesses and cut excess
costs. If we are unable to complete the integration of new businesses in a
timely manner, our results of operations and financial condition could be
adversely affected.

We are subject to risks relating to our foreign operations.

     Foreign operations represent a significant portion of our business. For the
first nine months of fiscal 2002, approximately 29% of our revenue was derived
from customers outside of the United States. We expect revenue from foreign
markets to continue to represent a significant portion of our total revenue. In
addition, we own or lease operating facilities in over 40 foreign countries. Our
foreign operations are subject to risks in addition to the risks of our domestic
operations. The risks that relate to our foreign operations include:

     o    potential political, economic and social instability in the foreign
          countries in which we operate;

     o    imposition of or increases in currency exchange controls;

     o    potential inflation in the applicable foreign economies;

     o    imposition of or increases in import duties and other tariffs on our
          products;

     o    imposition of or increases in foreign taxation of our earnings and
          withholding on payments received by us from our subsidiaries;

     o    regulatory changes affecting our international operations; and

     o    stringent labor regulations.

     If we are unable to successfully manage the risks associated with expanding
our global business or to adequately manage operational fluctuations
internationally, it could have a material effect on our business, results of
operations or financial condition.

Demand for and supply of our products may be adversely affected by numerous
factors, some of which we cannot predict or control, which could adversely
affect our results of operations.

     Numerous factors may affect the demand for and supply of our products,
including:

     o    changes in the market acceptance of our products;

     o    increased competition in the markets we serve;

     o    declines in the general level of industrial production; or


                                       2



     o    declines in the availability or increases in the prices of raw
          materials.

If any of these factors occur, the demand for and supply of our products could
suffer, which would adversely affect our results of operations.

We operate in a highly competitive environment.

     Our domestic and foreign operations are subject to significant competitive
pressures. To compete successfully, our Industrial Segment and Other Segment
must excel in terms of product quality and innovation, customer service,
manufacturing and distribution capability and competitive price, and our
Aerospace Segment must excel on the basis of technological and engineering
capability, quality, delivery and service, and price competitiveness. The
financial resources of certain of our competitors may put us a competitive
disadvantage.

We may be adversely affected by the impact of environmental and safety
regulations to which we are subject.

     Our operations necessitate the use and handling of hazardous materials and,
as a result, we are subject to various federal, state and local laws and
regulations designed to protect the environment and to regulate the discharge of
materials into the environment. These laws impose penalties, fines and other
sanctions for non-compliance and liability for response costs, property damages
and personal injury resulting from past and current spills, disposals or other
releases of, or the exposure to, hazardous materials. Among other laws, we are
subject to the federal "Superfund" law, under which we have been designated as a
"potentially responsible party" and may be liable for cleanup costs associated
with various waste sites, some of which are on the U.S. Environmental Protection
Agency's Superfund priority list. We could incur substantial costs as a result
of the noncompliance with or liability for cleanup or other costs or damages
under environmental laws, including the Superfund law.

     We may be subject to more stringent environmental laws in the future. If
more stringent environmental laws are enacted in the future, these laws could
have a material adverse effect on our business, results of operations or
financial condition.

                   DISCLOSURE ABOUT FORWARD-LOOKING STATEMENTS

     This prospectus contains or incorporates by reference statements that do
not directly or exclusively relate to historical facts. These types of
statements are forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. You can typically identify
forward-looking statements by the use of forward-looking words, such as "may,"
"will," "could," "project," "believe," "anticipate," "expect," "estimate,"
"continue," "potential," "plan" and "forecast." Those statements represent our
intentions, plans, expectations, assumptions and beliefs about future events and
are subject to risks, uncertainties and other factors. Many of those factors are
outside of our control and could cause actual results to differ materially from
the results expressed or implied by the forward-looking statements. Those
factors include:

     o    changes in business relationships with and purchases by or from major
          customers or suppliers, including delays or cancellations in
          shipments;

     o    ability of suppliers to provide materials as needed;

     o    uncertainties surrounding timing, successful completion or integration
          of acquisitions;

     o    competitive market conditions and resulting effects on sales and
          pricing;

     o    increases in raw-material and other production costs that cannot be
          recovered in product pricing;


                                       3



     o    threats associated with terrorism;

     o    difficulties in introducing new products and entering new markets; and

     o    uncertainties surrounding the global economy and global market
          conditions, including any federal government policies to stimulate the
          economy, interest rate levels and the potential devaluation of
          currencies.

     These and other factors are discussed in our reports filed with the SEC. In
light of these risks, uncertainties and assumptions, the forward-looking events
referred to in this prospectus might not occur. We undertake no obligation to
publicly update or revise any forward-looking statements, whether as a result of
new information, future events or otherwise.

of the common shares offered by this prospectus.

                         DETERMINATION OF OFFERING PRICE

     The common shares are being registered for sale on a continuous basis
pursuant to Rule 415 of the Securities Act of 1933 and the selling shareholder
may sell the shares from time to time on one or more exchanges or the
over-the-counter market in regular brokerage transactions, in transactions
directly with market makers or in privately-negotiated transactions at prices
and on terms prevailing at the time of any such sale. The price to the public,
underwriting discounts and commissions and net proceeds to the selling
shareholder from the sale of the shares will depend on the nature and timing of
the sales and therefore will not be known until the sales are actually made, if
at all.

     the selling shareholder under the Purchase Agreement. The exact number of

                              PLAN OF DISTRIBUTION

     We are registering all 294,676 shares on behalf of the selling shareholder.
The selling shareholder or its pledgees, donees, transferees or other
successors-in-interest selling shares received from the selling shareholder as a
gift, partnership distribution or other non-sale-related transfer after the date
of this prospectus may sell the shares from time to time. The selling
shareholder may also decide not to sell all the shares it is allowed to sell
under this prospectus. The selling shareholder will act independently of us in
making decisions with respect to the timing, manner and size of each sale. The
sales may be made on one or more exchanges or in the over-the-counter market or
otherwise, at prices and at terms then prevailing or at prices related to the
then current market prices, or in negotiated transactions. The selling
shareholder may effect such transactions by selling the shares to or through
broker-dealers. The shares may be sold by one or more of, or a combination of,
the following:

     o    a block trade in which the broker-dealer so engaged will attempt to
          sell shares as agent but may position and resell a portion of the
          block as principal to facilitate the transaction,

     o    purchases by a broker-dealer as principal and re-sale by such
          broker-dealer for its account pursuant to this prospectus,

     o    an exchange distribution in accordance with the rules of such
          exchange,

     o    ordinary brokerage transactions and transactions in which the broker
          solicits purchasers, and

     o    privately negotiated transactions.

     To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. In effecting sales,
broker-dealers engaged by the selling shareholder may arrange for other
broker-dealers to participate in the re-sales.

     The selling shareholder may enter into hedging transactions with
broker-dealers in connection with distributions of shares or otherwise. In such
transactions, broker-dealers may engage in short sales of shares in the course
of hedging the positions they assume with the selling shareholder. The selling
shareholder also may sell shares short and redeliver shares to close out such
short positions. The selling shareholder may enter into option or other
transactions with broker-dealers which require the delivery of


                                       6



shares to the broker-dealer. The broker-dealer may then resell or otherwise
transfer such shares pursuant to this prospectus. The selling shareholder also
may lend or pledge shares to a broker-dealer. The broker-dealer may sell the
shares so loaned, or upon a default the broker-dealer may sell the shares so
pledged, pursuant to this prospectus.

     Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from the selling shareholder.
Broker-dealers or agents may also receive compensation from the purchasers of
shares for whom they act as agents or to whom they sell as principals, or both.
Compensation to a particular broker-dealer might be in excess of customary
commissions and will be in amounts to be negotiated in connection with
transactions involving shares. Broker-dealers or agents and any other
participating broker-dealers or the selling shareholder may be deemed to be an
"underwriter" within the meaning of Section 2(11) of the Securities Act of 1933
in connection with sales of shares. Accordingly, any such commission, discount
or concession received by them and any profit on the re-sale of shares purchased
by them may be deemed to be underwriting discounts or commissions under the
Securities Act of 1933. Because the selling shareholder may be deemed to be an
"underwriter" within the meaning of Section 2(11) of the Securities Act of 1933,
the selling shareholder will be subject to the prospectus delivery requirements
of the Securities Act of 1933. In addition, any shares covered by this
prospectus which qualify for sale pursuant to Rule 144 promulgated under the
Securities Act of 1933 may be sold under Rule 144 rather than pursuant to this
prospectus. The selling shareholder has advised us that it has not entered into
any agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of its shares.

     The shares may be sold only through registered or licensed brokers or
dealers if required under applicable state securities laws. In addition, in
certain states the shares may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with.

     Under applicable rules and regulations under the Exchange Act of 1934, any
person engaged in the distribution of shares may not simultaneously engage in
market making activities with respect to our common shares for a period of two
business days prior to the commencement of such distribution. In addition, the
selling shareholder will be subject to applicable provisions of the Exchange Act
of 1934 and the associated rules and regulations under the Exchange Act of 1934,
including Regulation M, which provisions may limit the timing of purchases and
sales of shares of our common shares by the selling shareholder. We will make
copies of this prospectus available to the selling shareholder and have informed
them of the need for delivery of copies of this prospectus to purchasers at or
prior to the time of any sale of the shares.

     We will file a supplement to this prospectus, if required, pursuant to Rule
424 under the Securities Act of 1933 upon being notified by the selling
shareholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares through a block trade, special offering,
exchange distribution or secondary distribution or a purchase by a broker or
dealer. Such supplement will disclose:

     o    the name of the selling shareholder and of the participating
          broker-dealer(s),

     o    the number of shares involved,

     o    the price at which such shares were sold,

     o    the commissions paid or discounts or concessions allowed to such
          broker-dealer(s), where applicable,

     o    that such broker-dealer(s) did not conduct any investigation to verify
          the information set out or incorporated by reference in this
          prospectus, and

     o    other facts material to the transaction.


                                       7



     We will bear all costs, expenses and fees in connection with the
registration of the shares. The selling shareholder will bear all commissions
and discounts, if any, attributable to the sales of the shares. The selling
shareholder may agree to indemnify any broker-dealer or agent that participates
in transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act.

                                  LEGAL MATTERS

     Thomas A. Piraino, Jr., Parker's Vice President, General Counsel and
Secretary, will pass upon the validity of our common shares offered hereby.

Item 15. Indemnification of Directors and Officers.

     Section VII of our regulations provides that we will indemnify, to the
fullest extent permitted or authorized by the Ohio Revised Code, as it may from
time to time be amended and including Section 1701.13(E), any person made party
or who is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he or she is or was a member of our
board of directors or an officer, employee or agent of ours, or is or was
serving at our request as a director, trustee, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise. The
indemnification provided by our regulations is not exclusive of any other rights
to which any person seeking indemnification may be entitled under our articles
or our regulations, or any agreement, vote of shareholders or disinterested
directors, or otherwise. This extends to both his or her official actions and
his or her actions in another capacity while holding a position with us.
Further, coverage shall continue as to a person who has ceased to be our
director, trustee, officer or employee and shall inure to the benefit of his or
her heirs, executors and administrators.

     Section 1701.13(E) of the Ohio Revised Code provides as follows:

          (E)(1) A corporation may indemnify or agree to indemnify any person
     who was or is a party, or is threatened to be made a party, to any
     threatened, pending, or completed action, suit, or proceeding, whether
     civil, criminal, administrative, or investigative, other than an action by
     or in the right of the corporation, by reason of the fact that he is or was
     a director, officer, employee, or agent of the corporation, or is or was
     serving at the request of the corporation as a director, trustee, officer,
     employee, member, manager, or agent of another corporation, domestic or
     foreign, nonprofit or for profit, a limited liability company, or a
     partnership, joint venture, trust, or other enterprise, against expenses,
     including attorney's fees, judgments, fines, and amounts paid in settlement
     actually and reasonably incurred by him in connection with such action,
     suit, or proceeding, if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation, and, with respect to any criminal action or proceeding, if he
     had no reasonable cause to believe his conduct was unlawful. The
     termination of any action, suit, or proceeding by judgment, order,
     settlement, or conviction, or upon a plea of nolo contendere or its
     equivalent, shall not, of itself, create a presumption that the person did
     not act in good faith and in a manner he reasonably believed to be in or
     not opposed to the best interests of the corporation, and, with respect to
     any criminal action or proceeding, he had reasonable cause to believe that
     his conduct was unlawful.

          (2) A corporation may indemnify or agree to indemnify any person who
     was or is a party, or is threatened to be made a party, to any threatened,
     pending, or completed action or suit by or in


                                       II-1



     the right of the corporation to procure a judgment in its favor, by reason
     of the fact that he is or was a director, officer, employee, or agent of
     the corporation, or is or was serving at the request of the corporation as
     a director, trustee, officer, employee, member, manager, or agent of
     another corporation, domestic or foreign, nonprofit or for profit, a
     limited liability company, or a partnership, joint venture, trust, or other
     enterprise, against expenses, including attorney's fees, actually and
     reasonably incurred by him in connection with the defense or settlement of
     such action or suit, if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation, except that no indemnification shall be made in respect of any
     of the following:

          (a) Any claim, issue, or matter as to which such person is adjudged to
          be liable for negligence or misconduct in the performance of his duty
          to the corporation unless, and only to the extent that, the court of
          common pleas or the court in which such action or suit was brought
          determines, upon application, that, despite the adjudication of
          liability, but in view of all the circumstances of the case, such
          person is fairly and reasonably entitled to indemnity for such
          expenses as the court of common pleas or such other court shall deem
          proper;

          (b) Any action or suit in which the only liability asserted against a
          director is pursuant to section 1701.95 of the Revised Code.

          (3) To the extent that a director, trustee, officer, employee, member,
     manager, or agent has been successful on the merits or otherwise in defense
     of any action, suit, or proceeding referred to in division (E)(1) or (2) of
     this section, or in defense of any claim, issue, or matter therein, he
     shall be indemnified against expenses, including attorney's fees, actually
     and reasonably incurred by him in connection with the action, suit, or
     proceeding.

          (4) Any indemnification under division (E)(1) or (2) of this section,
     unless ordered by a court, shall be made by the corporation only as
     authorized in the specific case, upon a determination that indemnification
     of the director, trustee, officer, employee, member, manager, or agent is
     proper in the circumstances because he has met the applicable standard of
     conduct set forth in division (E)(1) or (2) of this section. Such
     determination shall be made as follows:

          (a) By a majority vote of a quorum consisting of directors of the
          indemnifying corporation who were not and are not parties to or
          threatened with the action, suit, or proceeding referred to in
          division (E)(1) or (2) of this section;

          (b) If the quorum described in division (E)(4)(a) of this section is
          not obtainable or if a majority vote of a quorum of disinterested
          directors so directs, in a written opinion by independent legal
          counsel other than an attorney, or a firm having associated with it an
          attorney, who has been retained by or who has performed services for
          the corporation or any person to be indemnified within the past five
          years;

          (c) By the shareholders;

          (d) By the court of common pleas or the court in which the action,
          suit, or proceeding referred to in division (E)(1) or (2) of this
          section was brought.

          Any determination made by the disinterested directors under division
     (E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this
     section shall be promptly communicated to the person who threatened or
     brought the action or suit by or in the right of the corporation under
     division (E)(2) of this section, and, within ten days after receipt of such
     notification, such person shall have the right to petition the court of
     common pleas or the court in which such action or suit was brought to
     review the reasonableness of such determination.


                                       II-2



          (5)(a) Unless at the time of a director's act or omission that is the
          subject of an action, suit, or proceeding referred to in division
          (E)(1) or (2) of this section, the articles or the regulations of a
          corporation state, by specific reference to this division, that the
          provisions of this division do not apply to the corporation and unless
          the only liability asserted against a director in an action, suit, or
          proceeding referred to in division (E)(1) or (2) of this section is
          pursuant to section 1701.95 of the Revised Code, expenses, including
          attorney's fees, incurred by a director in defending the action, suit,
          or proceeding shall be paid by the corporation as they are incurred,
          in advance of the final disposition of the action, suit, or
          proceeding, upon receipt of an undertaking by or on behalf of the
          director in which he agrees to do both of the following:

               (i) Repay such amount if it is proved by clear and convincing
          evidence in a court of competent jurisdiction that his action or
          failure to act involved an act or omission undertaken with deliberate
          intent to cause injury to the corporation or undertaken with reckless
          disregard for the best interests of the corporation;

               (ii) Reasonably cooperate with the corporation concerning the
          action, suit, or proceeding.

          (b) Expenses, including attorney's fees, incurred by a director,
          trustee, officer, employee, member, manager, or agent in defending any
          action, suit, or proceeding referred to in division (E)(1) or (2) of
          this section, may be paid by the corporation as they are incurred, in
          advance of the final disposition of the action, suit, or proceeding,
          as authorized by the directors in the specific case, upon receipt of
          an undertaking by or on behalf of the director, trustee, officer,
          employee, member, manager, or agent to repay such amount, if it
          ultimately is determined that he is not entitled to be indemnified by
          the corporation.

          (6) The indemnification authorized by this section shall not be
     exclusive of, and shall be in addition to, any other rights granted to
     those seeking indemnification under the articles, the regulations, any
     agreement, a vote of shareholders or disinterested directors, or otherwise,
     both as to action in their official capacities and as to action in another
     capacity while holding their offices or positions, and shall continue as to
     a person who has ceased to be a director, trustee, officer, employee,
     member, manager, or agent and shall inure to the benefit of the heirs,
     executors, and administrators of such a person.

          (7) A corporation may purchase and maintain insurance or furnish
     similar protection, including, but not limited to, trust funds, letters of
     credit, or self-insurance, on behalf of or for any person who is or was a
     director, officer, employee, or agent of the corporation, or is or was
     serving at the request of the corporation as a director, trustee, officer,
     employee, member, manager, or agent of another corporation, domestic or
     foreign, nonprofit or for profit, a limited liability company, or a
     partnership, joint venture, trust, or other enterprise, against any
     liability asserted against him and incurred by him in any such capacity, or
     arising out of his status as such, whether or not the corporation would
     have the power to indemnify him against such liability under this section.
     Insurance may be purchased from or maintained with a person in which the
     corporation has a financial interest.

          (8) The authority of a corporation to indemnify persons pursuant to
     division (E)(1) or (2) of this section does not limit the payment of
     expenses as they are incurred, indemnification, insurance, or other
     protection that may be provided pursuant to divisions (E)(5), (6), and (7)
     of this section. Divisions (E)(1) and (2) of this section do not create any
     obligation to repay or return payments made by the corporation pursuant to
     division (E)(5), (6), or (7).

          (9) As used in division (E) of this section, "corporation" includes
     all constituent entities in a consolidation or merger and the new or
     surviving corporation, so that any person who is or was a director,
     officer, employee, trustee, member, manager, or agent of such a constituent
     entity, or is or was serving at the request of such constituent entity as a
     director, trustee, officer, employee, member,


                                       II-3



     manager, or agent of another corporation, domestic or foreign, nonprofit or
     for profit, a limited liability company, or a partnership, joint venture,
     trust, or other enterprise, shall stand in the same position under this
     section with respect to the new or surviving corporation as he would if he
     had served the new or surviving corporation in the same capacity.

     We carry directors' and officers' liability insurance that covers certain
liabilities and expenses of our directors and officers.

Item 17. Undertakings.

     The undersigned registrant hereby undertakes:

     1. To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;


                                       II-4



          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective Registration Statement; and

          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the Registration Statement or any
     material change to such information in the Registration Statement;

provided, however, that the undertakings set forth in paragraphs (1)(i) and
(1)(ii) above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the registrant pursuant to section
13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this Registration Statement.

     2. That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     3. To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     4. That, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     5. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
