(1) Consists of 1,000,000 shares of common stock, par value $.10 per share (the
"Common Stock") reserved for issuance to employees of Kirby Corporation (the
"Corporation") pursuant to the 2001 Employee Stock Option Plan for Kirby
Corporation (the "2001 Employee Plan") and 300,000 shares of Common Stock
reserved for issuance to directors of the Corporation pursuant to the 2000
Nonemployee Director Stock Option Plan for Kirby Corporation (the "Nonemployee
Director Plan," and together with the 2001 Employee Plan, the "Plans"). In
addition, pursuant to Rule 416 under the Securities Act of 1933, this
Registration Statement also covers an indeterminate number of additional shares
of Common Stock issuable pursuant to the exercise of options and/or awards
granted or to be granted under the Plans to prevent dilution that may result
from any future stock splits, stock dividends or similar transactions affecting
the Common Stock.
(2)  Estimated solely for the purpose of computing the registration fee.
(3) Calculated pursuant to Rule 457(c) and (h). Accordingly, the price per share
of common stock offered hereunder pursuant to the Plans is based upon 942,000
shares of Common Stock reserved for issuance under the Plans at a price of
$26.37, which is the average of the highest and lowest price per share of
Common Stock on the New York Stock Exchange on October 30, 2001; and (ii)
258,000 shares of Common Stock reserved for issuance and subject to stock
options already granted under the 2001 Employee Plan at an exercise price of
$21.53 per share.
(4) An aggregate of 100,000 shares of the shares being registered under the
Nonemployee Director Plan are shares which were previously registered under the
2000 Director Stock Option Plan for Kirby Corporation (the "Predecessor Plan")
on the Registration Statement on Form S-8 (Registration No. 333-42794). The
Corporation has filed a post-effective amendment to deregister those shares, and
accordingly, the associated registration fee previously paid on these shares
under the prior registration statement is hereby also carried forward to cover
that portion of the registration fee under this Registration Statement that
corresponds to the shares which were previously available for grant under the
Predecessor Plan. Accordingly, the registration fee under this registration
statement is calculated with respect to 1,200,000 shares.

Indemnification of Directors and Officers ----------------------------------------- (a) The Restated Articles of Incorporation of the Corporation provide for indemnification as follows: "TWELFTH: 1. The Corporation shall 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, except 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, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he acted in good faith and in a manner which 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, has no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, and that, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful. 2. The Corporation shall 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 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, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys' fees actually and reasonably incurred by him in connection with the defense or

settlement of the action or suit if he acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation. Indemnification shall not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the Corporation or for amounts paid in settlement to the corporation unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. 3. To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in sections 1 and 2 of this Article Twelfth, or in defense of any claim, issue or matter therein, he must be indemnified by the corporation against expenses, including attorneys' fees, actually and reasonably incurred by him in connection with the defense. 4. Any indemnification under section 1 and 2 of this Article Twelfth, unless ordered by a court or advanced pursuant to section 5 of this Article Twelfth, must be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances. The determination must be made: (a) By the stockholders; (b) By the board of directors by majority vote of a quorum consisting of directors who were not parties to the act, suit or proceeding; (c) If a majority vote of a quorum consisting of directors who were not parties to the act, suit or proceeding so orders, by independent legal counsel in a written opinion; or (d) If a quorum consisting of directors who were not parties to the act, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion. 5. The expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding must be paid by the Corporation as they are incurred and in advance of the final disposition of the action, suit or proceeding upon receipt of an undertaking by or on behalf of the director

or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by the Corporation. The provisions of this section 5 of this Article Twelfth do no affect any rights to advancement of expenses to which corporate personnel other than directors or officers may be entitled under any contract or otherwise by law. 6. The indemnification and advancement of expenses provided by this Article Twelfth: (a) Does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under these articles of incorporation or any bylaws, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in his official capacity or an action in another capacity while holding his office, except that indemnification, unless ordered by a court pursuant to section 2 of this Article Twelfth or for the advancement of expenses of any director or officer, if a final adjudication establishes that his acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and was material to the cause of action. (b) Continues for a person who has ceased to be a director, officer, employee or agent and inures to the benefit of the heirs, executors and administrators of such person. 7. The Corporation may purchase and maintain insurance or make other financial arrangements on behalf of 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, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise for any liability asserted against him and liability and expenses incurred by him in his capacity as a director, officer, employee or agent, or arising out of his status as such, whether or not the corporation has the authority to indemnify him against such liability and expenses. 8. The other financial arrangements made by the corporation pursuant to section 7 of this Article Twelfth may include the following: (a) The creation of a trust fund. (b) The establishment of a program of self-insurance. (c) The securing of its obligation of indemnification by granting a security interest or other lien on any assets of the Corporation.

(d) The establishment of a letter of credit, guaranty or surety. No financial arrangement made pursuant to this section may provide protection for a person adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable for intentional misconduct, fraud or a knowing violation of law, except with respect to the advancement of expenses or indemnification ordered by a court. 9. Any insurance or other financial arrangement made on behalf of a person pursuant to this Article Twelfth may he provided by the Corporation or any other person approved by the board of directors, even if all or part of the other person's stock or other securities is owned by the Corporation. 10. In the absence of fraud: (a) The decision of the board of directors as to the propriety of the terms and conditions of any insurance or other financial arrangement made pursuant to this Article Twelfth and the choice of the person to provide the insurance or other financial arrangement shall be conclusive; and (b) The insurance or other financial arrangement: (1) is not void or voidable; and (2) does not subject any director approving it to personal liability for his action, even if a director approving the insurance or other financial arrangement is a beneficiary of the insurance or other financial arrangement." (b) The Corporation's Bylaws provide that the Corporation shall indemnify each and every present and former director and officer of the Corporation, and each and every person who may have served at the Corporation's request as a director or officer of another corporation in which the Corporation owns shares of capital stock or of which the Corporation is a creditor (each of which other corporation is individually referred to herein as an "Other Enterprise"), against any and all expenses (including attorneys' fees) actually and necessarily incurred by him in connection with the defense of any action, suit or proceeding in which he was or is a party by reason of being or having been a director or officer of the Corporation or Other Enterprise to the fullest extent permitted by law. The rights of indemnification provided in the Bylaws are in addition to any other rights to which a person may otherwise be entitled by any other provisions of the Corporation's Restated Articles of Incorporation, statute, agreement, vote of stockholders or otherwise.

The Corporation's Bylaws further provide that the Corporation shall indemnify officers and directors of the Corporation, as well as other persons who serve as agents and employees of the Corporation, to the extent set forth in the Corporation's Restated Articles of Incorporation. Additionally, the Corporation's Bylaws provide that the Corporation may purchase and maintain insurance on behalf of, and contractually agree to indemnify, 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, officer, employee or agent of another corporation, 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 the provisions of the Bylaws. (c) The Corporation has entered into agreements with each Director and certain key officers, including C. Berdon Lawrence, J.H. Pyne, Norman W. Nolen, Mark R. Buese, Jack M. Sims, Connie C. Power, Howard G. Runser, G. Stephen Holcomb and Thomas G. Adler, and certain officers of subsidiaries of the Corporation, including Steven P. Valerius and Dorman L. Strahan, that provide for the indemnification of such individuals for certain liabilities incurred in such capacity. Item 8. Exhibits. -------- (a) Exhibits.

Item 9. Undertakings. ------------ A. 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 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; (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; and (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. B. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933 (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 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference

in the 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. C. 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 of 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.

Each Option shall be evidenced by an option agreement containing any terms deemed necessary or desirable by the Committee that are not inconsistent with the Plan or applicable law. Section 2.2. Exercise Price. The exercise price per Share for any Option shall be determined by the Committee, but shall not be less than the Fair Market Value on the Date of Grant and shall not be less than 110% of the Fair Market Value on the Date of Grant for any Incentive Stock Option if the Optionee is a person who owns directly or indirectly (within the meaning of Section 422(b)(6) of the Code) stock possessing more than 10% of the total combined voting power of all classes of stock of the Company. Section 2.3. Term of Option. The term of an Option shall be determined by the Committee, provided that, in the case of an Incentive Stock Option, the term of the Option shall not exceed ten years from the Date of Grant unless the grant is to a person who owns directly or indirectly (within the meaning of Section 422(b)(6) of the Code) stock possessing more than 10% of the total combined voting power of all classes of the Company, in which case the term of the Option shall not exceed five years from the Date of Grant. Notwithstanding any other provision of this Plan, no Option shall be exercised after the expiration of its term. Section 2.4. Vesting. Options shall be exercisable at such times and subject to such terms and conditions as the Committee shall specify in the option agreement. Unless the option agreement specifies otherwise, the Committee shall have discretion at any time to accelerate such times and otherwise waive or amend any conditions in respect of all or any portion of the Options held by any Optionee. Notwithstanding the other provisions of this Section 2.4 and unless otherwise provided in the option agreement, upon the occurrence of a Change in Control, all Options outstanding at the time of the Change in Control shall become immediately exercisable.

Section 2.5. Termination of Options. (a) Except as otherwise provided in the option agreement, the portion of an Option that is exercisable shall automatically and without notice terminate upon the earliest to occur of the following: (i) thirty (30) days after the date on which Optionee ceases to be an Employee for any reason other than (x) death, (y) mental or physical disability as determined by a medical doctor satisfactory to the Committee or (z) termination for cause; (ii) one (1) year after the date on which Optionee ceases to be an Employee as a result of a mental or physical disability as determined by a medical doctor satisfactory to the Committee; (iii) either (y) one (1) year after the death of Optionee or (z) six (6) months after the death of Optionee if Optionee dies during the 30-day period described in Section 2.5(a)(i) or the one-year period described in Section 2.5(a)(ii); (iv) the date on which Optionee ceases to be an Employee as a result of a termination for cause; and (v) the tenth anniversary of the Date of Grant of the Option. (b) The portion of an Option that is not exercisable shall automatically and without notice terminate on the date on which Optionee ceases to be an Employee for any reason. (c) The Committee shall have discretion at any time to extend the term of any Nonincentive Stock Option to any date that is not later than the date described in Section 2.5(a)(v). Section 2.6. Exercise of Options. An Option may be exercised in whole or in part to the extent exercisable in accordance with Section 2.4 and the option agreement. An Option shall be deemed exercised when (i) the Company has received written notice of such exercise in accordance with the terms of the Option and (ii) full payment of the aggregate exercise price of the Shares as to which the Option is exercised has been made. Unless further limited by the Committee in any Option, the exercise price of any Shares purchased shall be paid solely in cash, by certified or cashier's check, by money order, by personal check or with Shares owned by the Optionee for at least six months, or by a combination of the foregoing. If the exercise price is paid in whole or in part with Shares, the value of the Shares surrendered shall be their Fair Market Value on the date received by the Company.

Section 2.7. Adjustment of Shares. (a) If at any time while the Plan is in effect or unexercised Options are outstanding, there shall be any increase or decrease in the number of issued and outstanding Shares through the declaration of a stock dividend or through any recapitalization resulting in a stock split, combination or exchange of Shares, then and in such event: (i) appropriate adjustment shall be made in the maximum number of Shares then subject to being optioned under the Plan so that the same proportion of the Company's issued and outstanding Shares shall continue to be subject to being so optioned, and (ii) appropriate adjustment shall be made in the number of Shares and the exercise price per Share thereof then subject to any outstanding Option, so that the same proportion of the Company's issued and outstanding Shares shall remain subject to purchase at the same aggregate exercise price. (b) In the event of a merger, consolidation or other reorganization of the Company in which the Company is not the surviving entity, the Board or the Committee may provide for any or all of the following alternatives: (i) for Options to become immediately exercisable, (ii) for exercisable Options to be cancelled immediately prior to such transaction, (iii) for the assumption by the surviving entity of the Plan and the Options, with appropriate adjustments in the number and kind of shares and exercise prices or (iv) for payment in cash or stock in lieu of and in complete satisfaction of Options. (c) Any fractional shares resulting from any adjustment under this Section 2.7 shall be disregarded and each Option shall cover only the number of full shares resulting from such adjustment. (d) Except as otherwise expressly provided herein, the issuance by the Company of shares of its capital stock of any class, or securities convertible into shares of capital stock of any class, either in connection with direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or

obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of or exercise price of Shares then subject to outstanding Options granted under the Plan. (e) Without limiting the generality of the foregoing, the existence of outstanding Options granted under the Plan shall not affect in any manner the right or power of the Company to make, authorize or consummate (i) any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its business; (ii) any merger or consolidation of the Company; (iii) any issue by the Company of debt securities, or preferred or preference stock that would rank above the Shares subject to outstanding Options; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the assets or business of the Company; or (vi) any other corporate act or proceeding, whether of a similar character or otherwise. Section 2.8. Transferability of Options. An Option shall not be transferable by the Optionee otherwise than by will or the laws of descent and distribution. So long as an Optionee lives, only such Optionee or his or her guardian or legal representative shall have the right to exercise such Option. Section 2.9. Issuance of Shares. No person shall be, or have any of the rights or privileges of, a stockholder of the Company with respect to any of the Shares subject to any Option unless and until certificates representing such Shares shall have been issued and delivered to such person. ARTICLE III. RESTRICTED STOCK Section 3.1. Grant of Restricted Stock Awards. The Committee may from time to time grant Restricted Stock Awards to Eligible Persons. Subject to the provisions of the Plan and applicable law, all Restricted Stock Awards under the Plan shall be in such form and shall have such terms and conditions as the Committee, in its discretion, may from time to time determine. Section 3.2. Terms and Conditions of Restricted Stock Awards. Each Restricted Stock Award shall specify the number of shares of Restricted Stock awarded, the price, if any, to be paid by the Participant receiving the Restricted Stock Award and the date or dates on which the Restricted Stock will vest. The vesting and number of shares of Restricted Stock may be conditioned upon the completion of a specified period of service with the Company or its Subsidiaries or upon the attainment of any performance goals established by the Committee, including without limitation goals related to the performance of the Company or any Subsidiary, division, department or other unit of the Company, the performance of the Company's common stock or other securities, the performance of the recipient of the Restricted Stock Award or any combination of the foregoing. Section 3.3. Restrictions on Transfer. Unless otherwise provided in the grant relating to a Restricted Stock Award, stock certificates representing the Restricted Stock granted to a Participant shall be registered in the Participant's name or, at the option of the Committee, not issued until such time as the Restricted Stock shall become vested or as otherwise determined by the Committee. If certificates are issued prior to the shares of Restricted Stock becoming vested, such certificates shall either be held by the Company on behalf of the Participant, or delivered to the Participant bearing a legend to restrict transfer of the certificate until the Restricted Stock has vested, as determined by the Committee. The Committee shall determine whether the Participant shall have the right to vote and/or receive dividends on the Restricted Stock before it has vested. Except as may otherwise be expressly permitted by the Committee, no share of Restricted Stock may be sold,

transferred, assigned or pledged by the Participant until such share has vested in accordance with the terms of the Restricted Stock Award. Unless the grant of a Restricted Stock Award specifies otherwise, in the event of a Participant's termination of employment before all the Participant's Restricted Stock has vested, or in the event other conditions to the vesting of Restricted Stock have not been satisfied prior to any deadline for the satisfaction of such conditions set forth in the award, the shares of Restricted Stock that have not vested shall be forfeited and any purchase price paid by the Participant shall be returned to the Participant. At the time Restricted Stock vests (and, if the Participant has been issued legended certificates for Restricted Stock, upon the return of such certificates to the Company), a certificate for such vested shares shall be delivered to the Participant (or the beneficiary designated by the Participant in the event of death), free of all restrictions. Section 3.4. Accelerated Vesting. Notwithstanding the vesting conditions set forth in a Restricted Stock Award, unless the Restricted Stock Award grant or other agreement with the Participant specifies otherwise: (a) the Committee may in its discretion at any time accelerate the vesting of Restricted Stock or otherwise waive or amend any conditions of a grant of a Restricted Stock Award, and (b) all shares of Restricted Stock shall vest upon a Change of Control of the Company. Section 3.5. Section 83(b) Election. If a Participant receives Restricted Stock that is subject to a "substantial risk of forfeiture," such Participant may elect under Section 83(b) of the Code to include in his or her gross income, for the taxable year in which the Restricted Stock is received, the excess of the Fair Market Value of such Restricted Stock on the Date of Grant (determined without regard to any restriction other than one which by its terms will never lapse), over the amount paid for the Restricted Stock. If the Participant makes the Section 83(b) election, the Participant shall (a) make such election in a manner that is satisfactory to the Committee, (b) provide the Company with a copy of such election, (c) agree to promptly notify the Company if any Internal Revenue Service or state tax agent, on audit or otherwise, questions the validity or correctness of such election or of the amount of income reportable on account of such election and (d) agree to such federal and state income tax withholding as the Committee may reasonably require in its sole discretion.

ARTICLE IV. ADDITIONAL PROVISIONS Section 4.1. Administration of the Plan. The Plan shall be administered by the Committee. The Committee shall have the authority to interpret the provisions of the Plan, to adopt such rules and regulations for carrying out the Plan as it may deem advisable, to decide conclusively all questions arising with respect to the Plan and to make all other determinations and take all other actions necessary or desirable for the administration of the Plan. All decisions and acts of the Committee shall be final and binding upon all affected Optionees and Participants. If there is no Committee, the Board shall administer the Plan and in such case all references to the Committee shall be deemed to be references to the Board. Section 4.2. Amendment. The Board may amend or modify the Plan in any respect at any time. Such action shall not impair any of the rights of any holder of any Option or Restricted Stock outstanding on the date of the amendment or modification without the holder's written consent. Section 4.3. Duration and Termination. The Plan shall be of unlimited duration, provided that no Incentive Stock Option shall be granted under the Plan on or after the tenth anniversary of the approval of the Plan by the stockholders of the Company. The Board may suspend, discontinue or terminate the Plan at any time. Such action shall not impair any of the rights of any holder of any Option or Restricted Stock outstanding on the date of the Plan's suspension, discontinuance or termination without the holder's written consent. Section 4.4. Withholding. Prior to the issuance of any Shares under the Plan, arrangements satisfactory to the Committee in its sole discretion shall have been made for the Optionee's or Participant's payment to the Company of the amount, if any, that the Committee determines to be necessary for the Company or Subsidiary employing the Optionee or Participant to withhold in accordance with applicable federal or state income tax withholding requirements. Section 4.5. Agreements and Undertakings. As a condition of any issuance or transfer of a certificate for Shares, the Committee may obtain such agreements or undertakings, if any, as it may deem necessary or advisable to assure compliance with any provision of the Plan, any agreement or any law or regulation including, but not limited to, the following: (a) a representation, warranty or agreement by the Optionee or Participant to the Company that the Optionee or Participant is acquiring the Shares for investment and not with a view to, or for sale in connection with, the distribution of any such Shares; and (b) a representation, warranty or agreement to be bound by any legends that are, in the opinion of the Committee, necessary or appropriate to comply with the provisions of any securities law deemed by the Committee to be applicable to the issuance of the Shares and are endorsed on the Share certificates.

Section 4.6. Governing Law. The Plan shall be governed by the laws of the State of Texas except to the extent that federal law or Nevada corporate law is controlling. Section 4.7. Effective Date. The Plan shall be effective as of January 15, 2001. If the Plan is not approved by a majority of the Company's stockholders represented in person or by proxy at a duly convened meeting on or before the first anniversary of the effective date of the Plan, (a) each Nonincentive Stock Option theretofore granted under the Plan shall remain outstanding, (b) each Incentive Stock Option theretofore granted under the Plan shall be deemed to be a Nonincentive Stock Option and shall remain outstanding as such, (c) any Restricted Stock theretofore granted under the Plan shall remain outstanding and (d) no further Options or Restricted Stock shall be granted under the Plan after the first anniversary of the effective date of the Plan or, if earlier, the date of a meeting of stockholders of the Company at which the Plan is proposed for approval but is not approved.

An Option shall be deemed exercised when (i) the Company has received written notice of such exercise in accordance with the terms of the Option and (ii) full payment of the aggregate option price of the Shares as to which the Option is exercised has been made. Unless further limited by the Committee in any Option, the option price of any Shares purchased shall be paid solely in cash, by certified or cashier's check, by money order, by personal check or with Shares owned by the

Optionee for at least six months, or by a combination of the foregoing. If the option price is paid in whole or in part with Shares, the value of the Shares surrendered shall be their Fair Market Value on the date received by the Company. 13. Adjustment of Shares. (a) If at any time while the Plan is in effect or unexercised Options are outstanding, there shall be any increase or decrease in the number of issued and outstanding Shares through the declaration of a stock dividend or through any recapitalization resulting in a stock split, combination or exchange of Shares, then and in such event: (i) appropriate adjustment shall be made in the maximum number of Shares then subject to being optioned under the Plan, and the numbers of Options to be granted under Sections 5, 6 and 7, so that the same proportion of the Company's issued and outstanding Shares shall continue to be subject to being so optioned, and (ii) appropriate adjustment shall be made in the number of Shares and the exercise price per Share thereof then subject to any outstanding Option, so that the same proportion of the Company's issued and outstanding Shares shall remain subject to purchase at the same aggregate exercise price. (b) In the event of a merger, consolidation or other reorganization of the Company in which the Company is not the surviving entity, the Board or the Committee may provide for any or all of the following alternatives: (i) for Options to become immediately exercisable, (ii) for exercisable Options to be cancelled immediately prior to such transaction, (iii) for the assumption by the surviving entity of the Plan and the Options, with appropriate adjustments in the number and kind of shares and exercise prices or (iv) for payment in cash or stock in lieu of and in complete satisfaction of Options. (c) Any fractional shares resulting from any adjustment under this Section 13 shall be disregarded and each Option shall cover only the number of full shares resulting from such adjustment. (d) Except as otherwise expressly provided herein, the issuance by the Company of shares of its capital stock of any class, or securities convertible into shares of capital stock of any class, either in connection with direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of or exercise price of Shares then subject to outstanding Options granted under the Plan. (e) Without limiting the generality of the foregoing, the existence of outstanding Options granted under the Plan shall not affect in any manner the right or power of the Company to make, authorize or consummate (i) any or all adjustments, recapitalizations, reorganizations or other changes in the

Company's capital structure or its business; (ii) any merger or consolidation of the Company; (iii) any issue by the Company of debt securities, or preferred or preference stock that would rank above the Shares subject to outstanding Options; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the assets or business of the Company; or (vi) any other corporate act or proceeding, whether of a similar character or otherwise. 14.

Issuance of Shares. No person shall be, or have any of the rights or privileges of, a stockholder of the Company with respect to any of the Shares subject to any Option unless and until certificates representing such Shares shall have been issued and delivered to such person. As a condition of any transfer of the certificate for Shares, the Committee may obtain such agreements or undertakings, if any, as it may deem necessary or advisable to assure compliance with any provision of the Plan, any agreement or any law or regulation including, but not limited to, the following: (a) a representation, warranty or agreement by the Optionee to the Company, at the time any Option is exercised, that the Optionee is acquiring the Shares for investment and not with a view to, or for sale in connection with, the distribution of any such Shares; and (b) a representation, warranty or agreement to be bound by any legends that are, in the opinion of the Committee, necessary or appropriate to comply with the provisions of any securities law deemed by the Committee to be applicable to the issuance of the Shares and are endorsed upon the Share certificates. 16. Administration of the Plan. The Plan shall be administered by the Committee. The Committee shall have the authority to interpret the provisions of the Plan, to adopt such rules and regulations for carrying out the Plan as it may deem advisable, to decide conclusively all questions arising with respect to the Plan and to make all other determinations and take all other actions necessary or desirable for the administration of the Plan. All decisions and acts of the Committee shall be final and binding upon all affected Optionees. If there is no Committee, the Board shall administer the Plan and in such case all references to the Committee shall be deemed to be references to the Board. 17. Amendment. The Board may amend or modify the Plan in any respect at any time. 18. Duration and Termination. The Plan shall be of unlimited duration. The Board may suspend, discontinue or terminate the Plan at any time. Such action shall not impair any of the rights of any holder of any Option outstanding on the date of the Plan's suspension, discontinuance or termination without the holder's written consent.

         Re:      Registration Statement on Form S-8

Gentlemen:

         We have acted as counsel to Kirby Corporation, a Nevada corporation
(the "Corporation"), in connection with the preparation of the Registration
Statement on Form S-8 (the "Registration Statement") to be filed with the
Securities and Exchange Commission on October 31, 2001, under the Securities
Act of 1933, as amended (the "Securities Act"), relating to 1,300,000 shares of
the $0.10 par value common stock (the "Common Stock") of the Corporation that
have been or may be issued upon the exercise of options granted or that may be
granted under the 2001 Employee Stock Option Plan for Kirby Corporation (the
"2001 Employee Plan") and 300,000 shares of Common Stock that have been or may
be issued upon exercise of options granted or that may be granted under the 2000
Nonemployee Director Stock Option Plan for Kirby Corporation (the "Nonemployee
Director Plan," and together with the 2001 Employee Plan, the "Plans").

         You have requested the opinion of this firm with respect to certain
legal aspects of the proposed offering. In connection therewith, we have
examined and relied upon the original, or copies identified to our satisfaction,
of (1) the Articles of Incorporation and the Bylaws of the Corporation, as
amended; (2) minutes and records of the corporate proceedings of the Corporation
with respect to the establishment of the Plans and the reservation of 1,000,000
shares of Common Stock to be issued under the 2001 Employee Plan and the
reservation of 300,000 shares of Common Stock to be issued under the Nonemployee
Director Plan to which the Registration Statement relates; (3) the Registration
Statement and exhibits thereto, including the Plans; and (4) such other
documents and instruments as we have deemed necessary for the expression of the
opinions herein contained. In making the foregoing examinations, we have assumed
the genuineness of all signatures and the authenticity of all documents
submitted to us as originals, and the conformity to original documents of all
documents submitted to us as certified or photostatic copies. As to various
questions of fact material to this opinion, and as to the content and form of
the Articles of Incorporation, the Bylaws, minutes, records, resolutions and
other documents or writings of the Corporation, we have relied, to the extent we
deem reasonably appropriate, upon representations or certificates of officers or
directors of the Corporation and upon documents, records and instruments
furnished to us by the Corporation, without independent check or verification of
their accuracy.

         Based upon our examination and consideration of, and reliance on, the
documents and other matters described above, and subject to the comments and
assumptions noted below, we are of the opinion that the Corporation presently
has available at least 1,300,000 shares of authorized but unissued shares of
Common Stock and/or treasury shares of Common Stock. From these shares of Common
Stock, the shares of Common Stock proposed to be sold through the 2001 Employee
Plan and Nonemployee Director Plan may be issued. Assuming that: (i) the
outstanding options were duly granted in accordance with the terms of the 2001
Employee Plan, the options to be granted in the future are duly granted in
accordance with the terms of the 2001 Employee Plan, and the shares of Common
Stock to be issued pursuant to the exercise of options under the 2001 Employee
Plan are duly issued in accordance with the terms of the 2001 Employee Plan,
(ii) the outstanding options were duly granted in accordance with the terms of
the Nonemployee Director Plan, the options to be granted in the future are duly
granted in accordance with the terms of the Nonemployee Director Plan, and the
shares of Common Stock to be issued pursuant to the exercise of options under
the Nonemployee Director Plan are duly issued in accordance with the terms of
the Nonemployee Director Plan, (iii) the Corporation maintains an adequate
number of authorized but unissued shares and/or treasury shares of Common Stock
available for issuance to those persons who exercise options pursuant to the
Plans, (iv) the consideration for shares of Common Stock issued pursuant to the
exercise of options under the 2001 Employee Plan is actually received by the
Corporation in accordance with the terms of the 2001 Employee Plan, and exceeds
the par value of such shares, and (v) the consideration for shares of Common
Stock issued pursuant to the exercise of options under the Nonemployee Director
Plan is actually received by the Corporation in accordance with the terms of the
Nonemployee Director Plan, and exceeds the par value of such shares, then we are
of the opinion that the shares of Common Stock issued pursuant to the exercise
of options and in accordance with the terms of the Plans, will be duly and
validly issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to references to our firm included in or made a part
of the Registration Statement. In giving this consent, we do not admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act or the Rules and Regulations of the Securities and Exchange
Commission thereunder.

                                           Very truly yours,

                                           JENKENS & GILCHRIST,
                                           a Professional Corporation
