                        STATEMENT PURSUANT TO RULE 13D-1
                                     OF THE
                         GENERAL RULES AND REGULATIONS
                                   UNDER THE
                  SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

Item 1.           Security and Issuer.

                  This Statement on Schedule 13D (this "Schedule 13D") relates
to the common stock, par value $0.10 per share (the "Common Stock"), of Kirby
Corporation, a Nevada corporation (the "Issuer"). The principal executive
offices of the Issuer are located at 1775 St. James Place, Suite 200, Houston,

Item 2.           Identity and Background.

Trusts are sometimes hereinafter collectively referred to as the "Reporting
Persons." Collectively, the Reporting Persons own more than 5% of the issued
and outstanding Common Stock. The Reporting Persons are making this single,
joint filing because they may be deemed to constitute a "group" within the
meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended

herein shall be deemed to be an admission by the Reporting Persons that a group
exists.

or administrative body of competent jurisdiction and as a result of such
proceeding was or is subject to a judgment, decree or final order enjoining

federal or state securities laws or finding any violation with respect to such
laws.
                  All of the natural persons identified in this Item 2 are
citizens of the United States of America.

Item 3.           Source and Amount of Funds or Other Consideration.

                  All of the shares of Common Stock acquired by the Reporting
Persons were acquired from the Issuer on October 12, 1999, upon the closing of
the transactions (the "Closing") set forth in that certain Agreement and Plan
of Merger (the "Merger Agreement") dated July 28, 1999, by and among the
Issuer, Kirby Inland Marine, Inc., a Delaware corporation and a wholly-owned
subsidiary of the Issuer ("KIM"), Hollywood Marine, Inc., a Texas corporation
all of the stock of which was held by the Reporting Persons ("HMI") and the
Reporting Persons. Under the Merger Agreement, HMI was merged with and into KIM
with KIM being the surviving entity. The Reporting Persons, being all of the
shareholders of HMI, exchanged all of the issued and outstanding common stock
of HMI for approximately $128,658,000 in cash and a total of 4,383,756 shares
of Common Stock (the "Shares").



                             (Page 11 of 20 Pages)
<PAGE>   12

                  Lawrence exchanged 66,334 shares of HMI common stock for
3,489,477 shares of Common Stock, plus a ratable share of the cash portion of
the merger consideration. Each of the GST Trusts exchanged 4,166 shares of HMI
common stock for 219,151 shares of Common Stock, plus a ratable share of the
cash portion of the merger consideration. The GRAT Trust, of which Lawrence is
a beneficiary, exchanged 336 shares of HMI common stock for 17,675 shares of
Common Stock, plus a ratable share of the cash portion of the merger
consideration. While Lawrence is not a beneficiary under any of the GST Trusts,
under the terms of the instruments pursuant to which the Trusts were created,
Lawrence does have the right to reacquire the property constituting the
principal of the Trusts, including, but not limited to, the Shares owned by the
Trusts, by substituting property of equal value therefor.

Item 4.           Purpose of Transaction.

                  The Reporting Persons acquired and continue to hold the
Shares reported herein for investment purposes. As discussed below, the Issuer
has agreed to cause (and did on October 19, 1999 cause) (i) Lawrence to be
designated as Chairman of the Board, (ii) the size of its Board of Directors
(the "Board") to be increased by two (2) members, and (iii) Lawrence and one
(1) other person mutually agreeable to Lawrence and the Board to be elected by
the Board to fill such newly created directorships. Lawrence and the Trusts
intend to participate in and influence the affairs of the Issuer through his
position as Chairman of the Board and his membership on the Board.

                  The Shares issued to the Reporting Persons by the Issuer have
not been registered under the Securities Act of 1933, as amended. Depending on
market conditions and other factors that each of the Reporting Persons may deem
material to his or its respective investment decision, such Reporting Person
may purchase additional shares of Common Stock in the open market or in private
transactions. Depending on these same factors, such Reporting Person may sell
all or a portion of the shares of Common Stock that he or it now owns or
hereafter may acquire on the open market or in private transactions.

                  It was a condition to Closing under the Merger Agreement that
the Issuer cause Lawrence to be designated as Chairman of the Board of the
Issuer. Additionally, it was a condition to Closing under the Merger Agreement
that the Issuer cause the size of the Board to be increased by two (2) members
and that the Issuer cause Lawrence and one (1) other person



                             (Page 12 of 20 Pages)
<PAGE>   13

mutually agreeable to Lawrence and the Board to be elected by the Board to fill
such newly created directorships. The Board approved such restructuring on
October 19, 1999, and Lawrence was elected to the Board and designated as
Chairman of the Board as of October 19, 1999.

                  Except as set forth in this Item 4, at the present time the
Reporting Persons do not have any plans or proposals that would relate to any
transaction, change or event specified in clauses (a) through (j) of Item 4 of
the Schedule 13D form.

Item 5.           Interest in Securities of the Issuer.

                  (a) As of October 12, 1999, the Reporting Persons owned an
aggregate of 4,383,756 shares of Common Stock, constituting approximately 17.9%
of the 24,503,245 shares of Common Stock stated to be outstanding as of October
12, 1999 in the Merger Agreement (including the Shares issued to the Reporting
Persons thereunder). The number and percentage of Shares beneficially owned by

                  While Lawrence is not a beneficiary under any of the GST
Trusts, under the terms of the instruments pursuant to which the Trusts were
created, Lawrence does have the right to reacquire the property constituting
the principal of the Trusts, including, but not limited to, the Shares owned by
the Trusts, by substituting property of equal value therefor.



                             (Page 13 of 20 Pages)
<PAGE>   14
                  (b) Lawrence has the sole power to vote or to direct the vote
and sole power to dispose or direct the disposition of the 3,489,477 Shares held
directly by him. Given Lawrence's power to reacquire the property constituting
the principal of the Trusts, including, but not limited to, the Shares owned by
the Trusts, Lawrence indirectly holds and an additional 894,279 shares, but
Lawrence has no power to vote or direct the vote or dispose or direct the
disposition of any of those Shares. As the Co-Trustees of the Trusts, Egan and
Rogers share the power to vote or to direct the vote and the power to dispose or
direct the disposition of all of the Shares held by them for the benefit of the
Trusts. Lawrence has the power to remove Egan and Rogers as Co-Trustees of the
Trusts.

                  (c) On October 12, 1999, each of the Reporting Persons
acquired the number of shares of Common Stock shown in Item 5(a) above. Such
Shares were issued to the Reporting Persons by the Issuer as part of the merger
consideration received by the Reporting Persons under the Merger Agreement. For
purposes of determining the number of shares of Common Stock to be issued to
the Reporting Persons under the Merger Agreement, each of the Shares was valued
at the average trading value on the New York Stock Exchange for the twenty (20)
trading days preceding three (3) days prior to Closing, which average trading
value was $20.4359 per share.

                  (d) As discussed below in Item 6, the Shares held by Egan and
Rogers as Co-Trustees for the benefit of the GST Trusts and any proceeds that
may result from any sales thereof are subject to Pledge and Security Agreements
executed by each of the GST Trusts in favor of Lawrence to secure repayment of
certain indebtedness of the GST Trusts to Lawrence (the "Security Agreements").
Under certain circumstances, the Security Agreements could give Lawrence the
right to receive, or the power to direct the receipt of dividends from, or the
power to direct the receipt of proceeds of the sale of such Shares.

                  (e) Not applicable.

Item 6.           Contracts, Arrangements or Understandings with Respect to
                  Securities of the Issuer.

                  On July 28, 1999, the Issuer, KIM, HMI and the Reporting
Persons entered into the Merger Agreement described in Item 3 of this Schedule
13D above. The Merger Agreement contained certain conditions to the Closing of
the transactions contemplated thereby, including



                             (Page 14 of 20 Pages)
<PAGE>   15

the changes in the composition of the Board as described in Item 4 of this
Schedule 13D and the expiration or termination of the applicable waiting
periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1974, as
amended, and the rules promulgated thereunder. The Merger Agreement also
required, among other things, that prior to the Closing (i) the Issuer and
Lawrence enter into an Employment Agreement providing for the employment of
Lawrence by the Issuer as the Chairman of the Board for a term of three (3)
years, and (ii) the Issuer and the Reporting Persons enter into a registration
rights agreement providing the Reporting Persons with the right, subject to
certain terms and conditions, to require the Issuer to register their Shares
for sale and to "piggy-back" on any registration of shares by the Issuer. On
October 12, 1999, all of these conditions were satisfied, and the Closing of
the transactions contemplated by the Merger Agreement occurred.

         Under the terms of the instruments pursuant to which the Trusts were
created, Lawrence has the power to reacquire the property constituting the
principal of the Trusts, including, but not limited to, the Shares owned by the
Trusts, by substituting property of equal value therefor.

                  The Shares held by Egan and Rogers as Co-Trustees for the
benefit of the GST Trusts and any proceeds that may result from any sales
thereof are subject to the Security Agreements. Under each of the Security
Agreements, the applicable Trust retains the right to receive, or the power to
direct the receipt of dividends from, and the power to direct the receipt of
proceeds of the sale of such Trust's Shares so long as no demand for repayment
of the subject indebtedness has been made. After demand for repayment of the
subject indebtedness has been made and so long as such demand has not been
rescinded and the subject indebtedness has not been paid in full, Lawrence has
the right to exercise all voting and other consensual rights with respect to
such Trust's Shares, to receive or direct receipt of dividends from such
Trust's Shares and to direct the receipt of proceeds from any sale of any of
such Trust's Shares.

Item 7.           Material to be Filed as Exhibits.

                  Exhibit A. Written agreement relating to the filing of joint
statement of acquisition pursuant to Rule 13d-1(f).

                  Exhibit B. Agreement and Plan of Merger dated July 28, 1999,

                          REGISTRATION RIGHTS AGREEMENT

         This REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of
October 12, 1999, by and among Kirby Corporation, a Nevada corporation (the
"Company"), and the individuals and entities listed on Exhibit A hereto
(collectively, the "Stockholders");

                              W I T N E S S E T H:

         WHEREAS, the Company and each of the Stockholders have entered into an
Agreement and Plan of Merger (the "Merger Agreement") dated as of July 28, 1999
relating to the receipt by Stockholders of an aggregate of 4,383,756 shares
(including any and all additional shares that may be issued pursuant to the
Merger Agreement, the "Shares") of Common Stock, par value $0.10 per share
("Common Stock"), of the Company;

         WHEREAS, in order to induce the Stockholders to enter into the Merger
Agreement, the Company has agreed to grant certain registration rights to the
Stockholders with respect to the Shares;

         NOW, THEREFORE, in consideration or the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

1.       Definitions.

         As used herein, the following terms have the indicated meanings, unless
the context otherwise requires:

         "Act" means the Securities Act of 1933, as amended.

         "Commission" means the Securities and Exchange Commission.

         "Exchange Act" means the Securities Exchange Act of 1934, as amended.

         "Holder" means a Stockholder who owns Registrable Securities or any
permitted transferee thereof who owns Registrable Securities.

         "Registrable Securities" means the Shares and any other securities
issued or issuable by the Company with respect to the Shares by way of a stock
dividend or other distribution or stock split or in connection with a
combination of shares, recapitalization, merger, consolidation or
reorganization. Any Registrable Securities will cease to be such when (i) a
registration statement covering such Registrable Securities has been declared
effective by the Securities and Exchange Commission and such Registrable
Securities have been disposed of pursuant to such effective registration
statement, (ii) such Registrable Securities may be distributed to the public
pursuant to Rule 144 (or any similar provision then in force) under the Act or
(iii) the Company has delivered a new certificate or other evidence of ownership
for such Registrable Securities not


<PAGE>   2

bearing the legend required pursuant to the Merger Agreement and such
Registrable Securities may be resold to the public without restriction under the
Act in accordance with Rule 144(k).

         "Selling Holder" means a Stockholder or permitted transferee thereof
who is selling Registrable Securities pursuant to a registration statement.

2.       Piggy-Back Registration Rights.

         (a) At any time following one (1) year from the date of this Agreement
that the Stockholders in the aggregate own at least 438,376 shares (as adjusted
for stock dividends, mergers, etc.) of the Registrable Securities, if the
Company proposes to file a registration statement under the Act with respect to
an offering by the Company of any class of equity security for cash, including
any security convertible into or exchangeable for any equity securities (other
than (i) a registration statement on Form S-4 or S-8 (or any substitute form for
comparable purposes that may be adopted by the Commission), (ii) a registration
statement filed in connection with an exchange offer or an offering of
securities solely to the Company's existing security holders or (iii) pursuant
to Article 3 hereto), then the Company shall in each case give written notice of
such proposed filing to the Holders at least 30 days before the anticipated
filing date, and such notice shall offer the Holders the opportunity to register
such number of Registrable Securities as each such Holder may request. Upon the
written request of any Holder received by the Company within 15 business days
after the date of the Company's delivery of its notice to the Holders of its
intention to file such a registration statement, the Company shall, subject to
the conditions and in accordance with the procedures set forth herein, use
reasonable efforts to cause the managing underwriter or underwriters, if any, of
a proposed underwritten offering to permit the Registrable Securities requested
by the Holder to be included in the registration statement for such offering on
the same terms and conditions as any securities of the Company included therein
(a "Piggy-Back Registration"). Notwithstanding the foregoing, if the managing
underwriter or underwriters of an offering indicates in writing to the Holders
who have requested that their Registrable Shares be included in such offering,
its reasonable belief that because of the size of the offering intended to be
made, the inclusion of the Registrable Securities requested to be included might
reasonably be expected to jeopardize the ability to complete the offering of the
securities of the Company to be offered and sold by the Company for its own
account, then the amount of securities to be offered for the account of the
Holders shall be reduced on a pro rata basis with all sellers (whether or not
such sellers are Holders) other than the Company to the extent necessary to
reduce the total amount of securities to be included in such offering to the
amount recommended by such managing underwriter or underwriters; provided
however, that in no event shall the amount of securities of the Selling Holders
included in the offering be reduced below 15% of the total amount of securities
included in such offering. The Company will bear all Registration Expenses (as
hereinafter defined) in connection with a Piggy-Back Registration.

         (b) The Company may, without the consent of any Selling Holder,
withdraw any registration statement prior to the effectiveness thereof and
abandon any proposed offering initiated by the Company, notwithstanding the
request of a Holder to participate therein in accordance with this Section if
the Company determines that such action is in the best interests of the Company.


                                        2
<PAGE>   3



         (c) Notwithstanding anything contained herein to the contrary, the
Company will have no obligation under this Section to register any Registrable
Securities unless at least _______ shares (as adjusted for stock splits, stock
dividends or similar transaction) of Registrable Securities in the aggregate are
requested to be included in such offering.

3.       Demand Registration Rights.

         (a) If at any time following one (1) year from the date of this
Agreement the Holders of at least 438,376 shares (as adjusted for stock
dividends, mergers, etc.) of the Registrable Securities ("Initiating Holders")
make a written request to the Company that the Company effect the registration
of such Registrable Securities under the Act, then the Company shall, within 5
business days of the receipt of such request, give written notice of such
request to all other Holders, and such notice shall offer the Holders the
opportunity to register such number of Registrable Securities as each such
Holder may request (a "Demand Registration"). Upon the written request of
Holders of the Registrable Securities received by the Company within 10 days
after the date of the Company's delivery of its notice to the Holders as
described in this Section, the Company will as promptly as reasonably
practicable, but in any event within 30 days of receipt of the initial request,
prepare and file with the Commission a registration statement ("Demand
Registration Statement") covering such proposed sale of all such Registrable
Shares requested to be so registered. The Company will bear all Registration
Expenses (as hereinafter defined) in connection with a Demand Registration. The
underwriter or underwriters for a requested registration shall be selected by
the mutual consent of the Company and C. Berdon Lawrence.

         (b) Subject to paragraph (d) below, the Company will use reasonable
efforts to have the Demand Registration Statement declared effective by the
Commission as soon as practicable after the filing thereof and to maintain the
effectiveness thereof for 90 days (or until all Registrable Shares covered
thereby have been sold, if such sales are completed before the end of the 90-day
period).

         (c) The Company shall only be required to provide two effective Demand
Registrations under this Section 4 and shall not be required to effect a Demand
Registration within 12 months of the last Demand Registration.

         (d) The Company will be entitled to postpone the filing of the Demand
Registration Statement for an aggregate number of days not exceeding 90 days
following the effectiveness of a registration statement filed by the Company in
connection with an underwritten public offering by the Company of any equity
securities within the 60 days preceding the date of the request. The Company
shall give prompt written notice to the Holders of any such postponement and
shall likewise give prompt written notice to the Holders of termination of such
postponement.

         (e) Limitations, Conditions and Qualifications Under Registration
Covenants. If, prior to the effectiveness of any registration statement
otherwise required to be prepared and filed by the Company pursuant to this
SECTION 3, of the Board of Directors of the Company determines in good faith
either (i) that the sale of the Registrable Securities pursuant to such
registration statement would require disclosure of material non-public
information, the disclosure of which would have a material adverse effect on the
Company (an "Information Blackout") or



                                       3
<PAGE>   4

(ii) that the Company is required, pursuant to the Exchange Act, to prepare
financial statements in connection with a material acquisition or other event (a
"Financial Statement Blackout"), and in either such case shall furnish to each
holder of Registrable Securities a certificate regarding such determination,
then the Company's obligation to effect such registration hereunder shall be
deferred for a period not to extend beyond the earliest of (x) the date upon
which such material information is disclosed to the public or ceases to be
material, in the case of an Information Blackout, or the date on which the
preparation of such financial statements is complete, in the case of a Financial
Statement Blackout, (y) 90 days after the Company's Board of Directors makes
such good faith determination and (z) the date on which the Company files or is
required to file (whichever first occurs) with the Commission its next periodic
report on Form 10-K or Form 10-Q (or any successor form) under the Exchange Act,
in the case of an Information Blackout, or the first date on which the Company
is required to file with the Commission a report on Form 10-K, Form 10-Q or Form
8-K under the Exchange Act that includes such financial statements in the case
of a Financial Statement Blackout (a "Blackout Period"); provided, that if any
such registration statement is effective, the Company may, upon written notice
of an Information Blackout or a Financial Statement Blackout, as the case may
be, to each holder of Registrable Securities, suspend sales of Registrable
Securities pursuant to such registration statement for the Blackout Period;
provided, further, that the cumulative duration of all Blackout Periods shall
not any event exceed 90 days during any twelve-month period. If the Company
shall postpone the filing of a registration statement pursuant to the preceding
provisions of this paragraph, holders of Registrable Securities with respect to
which registration has been requested and constituting not less that 15% of the
Registrable Securities with respect to which registration has been requested and
constituting not less that 50% of the Initiating Holders, shall have the right
to withdraw the request for registration by giving written notice to the Company
within 30 days after receipt of the notice of postponement and, in the event of
such withdrawal, such requested registration shall not be counted for purposes
of the requested registrations to which holders of Registrable Securities are
entitled pursuant to this SECTION 3.

4.       Restrictions on Public Sale by Holder of Registrable Securities.

         If and to the extent requested by the managing underwriter or
underwriters in the case of an underwritten public offering, each Selling Holder
whose Registrable Securities are included in a registration statement agrees not
to effect any public sale or distribution of the security being registered or a
similar security of the Company or any securities convertible into or
exchangeable or exercisable for such securities (including a sale pursuant to
Rule 144 under the Act) during a period not to exceed 90 days (such period to be
no longer than as may be required with respect to any officer or director of the
Company) beginning on the effective date of a registration statement.

5.       Registration and Marketing Procedures.

         Whenever the Holders have requested that any Registrable Securities be
included in a registration statement, the Company shall (unless such
registration statement is not filed or is withdrawn) use reasonable efforts to
effect the registration and the sale of such Registrable Securities as soon as
reasonably practicable, and in connection with any such request, the Company
shall (unless such registration statement is not filed or is withdrawn):

         (a) (i) prior to filing a registration statement or prospectus or any
amendments or supplements thereto, furnish to each Selling Holder and counsel
selected by each Selling Holder copies of all such documents proposed to be
filed, which documents will be subject to the review of such counsel, (ii)
furnish to each Selling Holder, prior to filing a registration statement, copies
of such registration statement as proposed to be filed, and thereafter furnish
to each Selling Holder such number of copies of such registration statement,
each amendment and supplement thereto (in each case including all exhibits
thereto), the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as any Selling Holder may
reasonably require in order to facilitate the disposition of the Registrable
Securities owned by the Selling Holder, and (iii) after the filing of the
registration statement, promptly notify each Selling Holder of Registrable
Securities covered by such registration statement of any stop order issued or
threatened by the Commission and take all reasonable actions required to prevent
the entry of such stop order or to remove it if entered;

         (b) use reasonable efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
each Selling Holder reasonably requests and do any and all other acts and things
which may be reasonably necessary or advisable to enable the Selling Holder to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by the Selling Holder; provided, however, that the Company will not be
required to (i) qualify generally to do business in any jurisdiction where it
would not otherwise be required to qualify but for this paragraph (b), (ii)
subject itself to taxation in any such jurisdiction where it is not then so
subject or (iii) consent to general service of process in any such jurisdiction;

         (c) use reasonable efforts to cause such Registrable Securities to be
registered with or approved by such other governmental agencies or authorities
as may be necessary by virtue of the business and operations of the Company to
enable the Selling Holder thereof to consummate the disposition of such
Registrable Securities;

         (d) notify the Selling Holder, at any time when a prospectus relating
thereto is required to be delivered under the Act, of the occurrence of an event
requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable Securities,
such prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading and promptly make available to the Selling
Holder any such supplement or amendment;

         (e) enter into or arrange for the furnishing of customary agreements
and documents (including an underwriting agreement in customary form) and take
such other actions as are



                                       5
<PAGE>   6


reasonably required in order to expedite or facilitate the disposition of such
Registrable Securities;

         (f) make available for inspection by each Selling Holder, any
underwriter participating in any disposition pursuant to such registration
statement and any attorney, accountant or other professional retained by the
Selling Holder or underwriter (collectively, the "Inspectors"), all financial
and other records, pertinent corporate documents and properties of the Company
and its subsidiaries (collectively, the "Records") as shall be reasonably
necessary to enable them to exercise their due diligence responsibility, and
cause the Company's and its subsidiaries' officers and employees to supply all
information reasonably requested by any such Inspector in connection with such
registration statement. Each Selling Holder agrees that information obtained by
it as a result of such inspections that is material and deemed confidential
shall not be used by it as the basis for any market transactions in securities
of the Company unless and until such is made generally available to the public.
The Selling Holder further agrees that it will, upon learning that disclosure of
such Records is sought in a court of competent jurisdiction, give notice to the
Company and allow the Company, at the Company's expense, to undertake
appropriate action to prevent disclosure of the Records deemed confidential;

         (g) otherwise comply with all applicable rules and regulations of the
Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering a period of 12 months, beginning
within three months after the effective date of the registration statement,
which earnings statement shall satisfy the provisions of Section 11 (a) of the
Act;

         (h) use its reasonable efforts to cause all such Registrable Securities
to be quoted on New York Stock Exchange, if the Common Stock is then so quoted,
or to be listed on any securities exchange on which the Common Stock is then
listed; and

         (i) assist in marketing the offering, including conducting and
participating in a roadshow as recommended and scheduled by the underwriters.

         The Company may require the Selling Holder as to which any registration
is being effected to furnish to the Company such information regarding the
Selling Holder and the distribution of such Registrable Securities as the
Company may from time to time reasonably request in writing and such other
information as may be legally required in connection with such registration.

         In no event shall the Company be required to amend any registration
statement filed pursuant to this Agreement after it has become effective or to
amend or supplement any prospectus to permit the continued disposition of shares
of Common Stock owned by a Selling Holder registered under any such registration
statement beyond the period during which the Company is required to maintain the
effectiveness thereof pursuant to the terms of this Agreement.

         Each Selling Holder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in paragraph (d)
above, the Selling Holder will forthwith discontinue disposition of Registrable
Securities pursuant to the registration statement



                                       6
<PAGE>   7

covering such Registrable Securities until the Selling Holder's receipt of the
copies of the supplemented or amended prospectus contemplated by paragraph (d)
above, and, if so directed by the Company, the Selling Holder will deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies then in the Selling Holder's possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice. Each
Selling Holder also agrees to notify the Company of any event relating to the
Selling Holder that occurs that would require the preparation of a supplement or
amendment to the prospectus so that such prospectus 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.

6.       Registration Expenses.

         All expenses incident to the Company's performance of or compliance
with this Agreement, including, without limitation, all registration and filing
fees, fees and expenses of compliance with securities or blue sky laws
(including fees and disbursements of counsel in connection with blue sky
qualifications of the Registrable Securities), rating agency fees, printing
expenses, messenger and delivery expenses, internal expenses (including, without
limitation, all salaries and expenses of its officers and employees performing
legal or accounting duties), the fees and expenses incurred in connection with
the listing of the securities to be registered on New York Stock Exchange and
all securities exchanges on which similar securities issued by the Company are
then quoted or listed, marketing expenses including all expenses for travel,
hotels and other roadshow expenses, and fees and disbursements of counsel for
the Company and its independent certified public accountants (including the
expenses of any special audit or comfort letters required by or incident to such
performance), securities act liability insurance (if the Company elects to
obtain such insurance), the fees and expenses of any special experts retained by
the Company in connection with such registration, and fees and expenses of other
persons retained by the Company, in connection with each registration hereunder
(but not including any underwriting discounts or commissions attributable to the
sale of Registrable Securities (which are hereinafter referred to as
"Discounts")) and the reasonable fees and expenses of one counsel for the
Selling Holders selected by them, (collectively, the "Registration Expenses")
will be borne by the Company in the event of a registration of Registrable
Securities. All Discounts shall be borne solely by the Selling Holders.

7.       Indemnification; Contribution.

         (a) Indemnification by the Company. To the extent permitted by
applicable law, the Company agrees to indemnify and hold harmless each Selling
Holder, its officers, directors, partners and agents and each person, if any,
who controls a Selling Holder within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages (whether in contract, tort or otherwise), liabilities and expenses
(including reasonable costs of investigation) whatsoever (as incurred or
suffered) arising out of or based upon any untrue statement or alleged untrue
statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or based
upon 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,



                                       7
<PAGE>   8

damages, liabilities or expenses arise out of, or are based upon, any such
untrue statement or omission or allegation thereof based upon information
furnished in writing to the Company by such Selling Holder or on behalf of such
Selling Holder expressly for use therein and provided, that with respect to any
untrue statement or omission or alleged untrue statement or omission made in any
preliminary prospectus, the indemnity agreement contained in this paragraph
shall not apply to the extent that any such loss, claim, damage, liability or
expense results from the fact that a current copy of the prospectus was not sent
or given to the person asserting any such loss, claim, damage, liability or
expense at or prior to the written confirmation of the sale of the Registrable
Securities concerned to such person if it is determined that the Company had
previously provided such Selling Holder with such current copy of the
prospectus, it was the responsibility of such Selling Holder to provide such
person with such current copy of the prospectus and such current copy of the
prospectus would have cured the defect giving rise to such loss, claim, damage,
liability or expense. The Company also agrees to indemnify any underwriters of
the Registrable Securities, their officers, partners and directors and each
person who controls such underwriters on substantially the same basis as that of
the indemnification of the Selling Holder provided in this article or such other
indemnification customarily obtained by underwriters at the time of offering.

         (b) Conduct of Indemnification Proceedings. If any action or proceeding
(including any governmental investigation) shall be brought or asserted against
a Selling Holder (or its officers, directors, partners, attorneys or agents) or
any person controlling such Selling Holder in respect of which indemnity may be
sought from the Company, the Company shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Selling Holder, and
shall assume the payment of all expenses. Each Selling Holder or any controlling
person of a Selling Holder shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Selling Holder or such
controlling person unless (i) the Company has agreed to pay such fees and
expenses or (ii) the named parties to any such action or proceeding (including
any impleaded parties) include both the Selling Holder or such controlling
person and the Company, and the Selling Holder or such controlling person shall
have been advised by counsel that there may be one or more legal defenses
available to such Selling Holder or such controlling person which are different
from or additional to those available to the Company (in which case, if such
Selling Holder or such controlling person notifies the Company in writing that
it elects to employ separate counsel at the expense of the Company, the Company
shall not have the right to assume the defense of such action or proceeding on
behalf of such Selling Holder or such controlling person) or (iii) the use of
counsel chosen by the Company to represent the Selling Holder would present such
counsel with a conflict of interest or (iv) the Company shall not have employed
counsel satisfactory to the Selling Holder to represent the Selling Holder
within a reasonable time after notice of the institution of such action; it
being understood, however, that the Company shall not, in connection with any
one such action or proceeding or separate but substantially similar or related
actions or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (together with appropriate local counsel) at any
time for each Selling Holder, which firm shall be designated in writing by such
Selling Holder). The Company shall not be liable for any settlement of any such
action or proceeding effected without the Company's written consent, but if
settled with its written consent, or if there be a final judgment for the
plaintiff in any such action or proceeding, the Company agrees to indemnify and
hold harmless



                                       8
<PAGE>   9

each Selling Holder and controlling person from and against any loss or
liability (to the extent stated above) by reason of such settlement or judgment.
The Company shall not, without the prior written consent of the Selling Holder,
settle or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
Selling Holders are actual or potential parties to such claim or action) unless
such settlement, compromise or consent includes an unconditional release of each
Selling Holder from all liability arising out of such claim, action, suit or
proceeding.

         (c) Indemnification by Selling Holders. Each Selling Holder agrees to
indemnify and hold harmless the Company, its directors and officers 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 the Selling Holder, but only with
respect to information furnished in writing by the Selling Holder or on the
Selling Holder's behalf expressly for use in any registration statement or
prospectus relating to the Registrable Securities, or any amendment or
supplement thereto, or any preliminary prospectus. In case any action or
proceeding shall be brought against the Company or its directors or officers, or
any such controlling person, in respect of which indemnity may be sought against
a Selling Holder, such Selling Holder shall have the rights and duties given to
the Company, and the Company or its directors or officers or such controlling
person shall have the rights and duties given to a Selling Holder, by the
preceding paragraph. The Selling Holder also agrees that it will enter into an
indemnity agreement to indemnify and hold harmless underwriters of the
Registrable Securities, their officers and directors and each person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Company provided in this paragraph (c). Notwithstanding
the foregoing, the liability of a Selling Holder pursuant to this paragraph (c)
shall not exceed the aggregate proceeds from the sale of the Registrable
Securities actually received by the Selling Holder.

         (d) Contribution. If the indemnification provided for in this article
is unavailable to the Company or a Selling Holder in respect of any losses,
claims, damages, liabilities or judgments referred to herein, then each such
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) as between the
Company and such Selling Holder on the one hand and the underwriters on the
other, in such proportion as is appropriate to reflect the relative benefits
received by the Company and a Selling Holder on the one hand and the
underwriters on the other from the offering of the Registrable Securities, or if
such allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and such Selling Holder on the one hand and of the
underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or judgments, as well as
any other relevant equitable considerations and (ii) as between the Company, on
the one hand, and a Selling Holder on the other, in such proportion as is
appropriate to reflect the relative fault of the Company and of such Selling
Holder in connection with such statements or omissions, as well as any other
relevant equitable considerations. The relative benefits received by the Company
and a Selling Holder on the one hand and the underwriters on the other shall be
deemed to be in the same proportion as the total proceeds from the offering (net
of underwriting discounts and commissions but before deducting expenses)
received by the Company and such Selling Holder



                                       9
<PAGE>   10

bear to the total underwriting discounts and commissions received by the
underwriters, in each case as set forth in the table on the cover page of the
prospectus. The relative fault of the Company and such Selling Holder on the one
hand and of the underwriters on the other 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 and such Selling Holder or by the
underwriters. The relative fault of the Company on the one hand and of such
Selling Holder on the other 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 such party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

         The Company and each Selling Holder agree that it would not be just and
equitable if contribution pursuant to this paragraph (d) were determined by pro
rata allocation (even if the underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities, or judgments 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 paragraph (d), no underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and a Selling Holder
shall not be required to contribute any amount in excess of the amount of the
total price at which the Registrable Securities of the Selling Holder were
offered to the public. 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.

         (e) Indemnification Payments. The indemnification and contribution
required by this Article shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills are
received or expense, loss, damage or liability are incurred.

8.       Participation in Underwritten Registrations.

         No person may participate in any underwritten registration hereunder
unless such person (a) agrees to sell such person's securities on the basis
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (b) completes and executes all
questionnaires, powers of attorney, custody agreements, indemnities,
underwriting agreements and other documents reasonably required by the Company
or managing underwriter under the terms of such underwriting arrangements and
this Agreement.



                                       10
<PAGE>   11

9.       Rule 144 and Reports.

         The Company shall timely file the reports required to be filed by it
under the Securities Act and the Exchange Act (including but not limited to the
reports under Sections 13 and 15(d) of the Exchange Act referred to in
subparagraph (c)(1) of Rule 144 adopted by the Commission under the Securities
Act) and the rules and regulations adopted by the Commission thereunder (or, if
the Company is not required to file such reports, will, upon the request of any
holder of Registrable Securities, make publicly available other information) and
will take such further action as any holder of Registrable Securities may
reasonably request, all to the extent required from time to time to enable such
holder to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by (a) Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the Commission. Upon the request
of any holder of Registrable Securities, the Company will deliver to such holder
a written statement as to whether it has complied with such requirements.

10.      Miscellaneous.

         (a) Binding Effect; Assignability. Unless otherwise provided herein,
the provisions of this Agreement shall be binding upon and accrue to the benefit
of the parties hereto and their respective heirs and legal representatives and
permitted transferees, successors and assigns. The rights and obligations of a
Holder hereunder cannot be assigned or transferred without the prior written
consent of the Company except (i) by will or intestacy or (ii) to a transferee
or assignee who after such transfer or assignment holds at least 438,376 shares
(as adjusted for stock dividends, mergers, etc.) of Registrable Securities.

         (b) Amendment. This Agreement may be amended or terminated only by a
written instrument signed by the Company and each of the Holders.

         (c) Applicable Law. The internal laws of the State of Texas (without
regard to choice of law provisions thereof) shall govern the interpretation,

                                    FORM OF

                         PLEDGE AND SECURITY AGREEMENT


         This PLEDGE AND SECURITY AGREEMENT (this "Agreement"), dated October
12, 1999, is made by and between Robert B. Egan and Eddy J. Rogers, Jr. as
trustees of the Berdon Lawrence GST Trust [number of Trust] (the "Debtor"), in
favor of C. Berdon Lawrence (the "Secured Party").

                                    RECITALS

         A.       The Secured Party is the legal owner and holder of that
certain Demand Note dated May 25, 1999, executed by the Debtor in favor of the
Holder in the original principal sum of $4,500,000 (the "Note").

         B.       The Note is secured by a Pledge and Security Agreement (the
"Security Agreement") dated May 25, 1999 by and among the Secured Party and the
Debtor pursuant to which the Debtor pledged its interest in 17,000 shares of
the common stock of Hollywood Marine, Inc. (the "Shares") to the Secured Party.

         C.       The Note is also secured by a Financing Statement (the
"Financing Statement") dated May 25, 1999, executed by the Secured Party and
the Debtor and covering the Debtor's interest in the Shares.

         D.       Hollywood Marine, Inc. ("HMI") has agreed to merge with Kirby
Inland Marine, Inc. ("KIM") pursuant to the certain Agreement and Plan of
Merger (the "Merger Agreement") dated July 28, 1999, by and among HMI, KIM,
Kirby Corporation ("Kirby"), and each of the shareholders of HMI.

         E.       It is a condition of the Merger Agreement that the liens on
the Shares created by the Security Agreement and the Financing Statement be
released.

         F.       The Debtor, as a shareholder of HMI, desires that the
transactions contemplated by the Merger Agreement be consummated.

         G.       The Secured Party has agreed to execute that certain Full
Release of Lien of even date herewith (the "Release") releasing the Shares and
the liens thereon created by the Security Agreement and the Financing Statement
and the Shares on the condition that the Debtor execute an alternate security
agreement and financing statement continuing the Secured Party's original
security interest and covering the consideration received by the Debtor under
the Merger Agreement for the Debtor's interest in the Shares, which
consideration constitutes proceeds of the Shares.

                                   AGREEMENT

         In consideration of the promises herein contained, and in order to
induce the Secured Party to execute the Release, the parties agree as follows:

         SECTION 1. Grant of Security Interest in Investment Account. As
collateral security for all of the Obligations (as defined in Section 2
hereof), the Debtor hereby pledges and assigns to the Secured Party, and grants
to the Secured Party a continuing security interest in, the following
(collectively, the "Collateral"):

         (a)      all of the Debtor's right, title and interest in and to that
certain investment account at Chase Bank of Texas, N.A. in Houston, Texas in
the name of the Debtor and bearing the account number 55010012082205 (the
"Investment Account") and all money, whether in currency of the United States
or any foreign country, on deposit therein, and all investments of whatever
kind and nature arising therefrom or held therein;

         (b)      all of the shares of Kirby common stock received by the
Debtor under the Merger Agreement as consideration for the Shares (the "Pledged
Shares"), the certificates representing the Pledged Shares, all options and
other rights, contractual or otherwise, in respect thereof and all dividends,
cash, instruments and other property from time to time received, receivable or
otherwise distributed in respect of or in exchange for any or all of the
Pledged Shares;

         (c)      all additional shares of stock, from time to time acquired by
the Debtor, of Kirby, the certificates representing such additional shares, all
options and other rights, contractual or otherwise, in respect thereof and all
dividends, cash, instruments and other property from time to time received,
receivable or otherwise distributed in respect of or in exchange for any or all
of such additional shares; and

         (d)      all proceeds and products of any and all of the foregoing;

in each case, however the Debtor's interest therein may arise or appear
(whether by ownership, security interest, claim or otherwise) (all such
Collateral described in the foregoing clauses (b) and (c) and any proceeds
therefrom being hereinafter collectively referred to as the "Pledged
Collateral").

         SECTION 2. Security for Obligations. This Agreement and the lien and
security interest created hereby in the Collateral secure the prompt and
complete:

         (a)      payment of all obligations of the Debtor to the Secured Party
now or hereafter existing under the Note and any other document related thereto
or executed in connection therewith to which the Debtor is a party, as each may
be modified, amended, extended or renewed from time to time; and

         (b)      performance and observance by the Debtor of all covenants,
conditions and agreements contained in the Note and any other documents related
thereto or executed in

                                       2
<PAGE>   3

connection therewith to which the Debtor is a party, as each may be modified,
amended, extended or renewed from time to time (including, without limitation,
the covenants, conditions and agreements contained herein), whether for
principal, interest, fees, expenses or otherwise;

all such obligations, covenants, conditions and agreements described in the
foregoing clauses (a) and (b) being hereinafter collectively referred to as the
"Obligations".

         SECTION 3. Delivery of the Pledged Shares; Filing of Financing
Statements.

         (a)      All certificates representing the Pledged Shares shall be
delivered to or at the direction of the Secured Party upon the execution and
delivery of this Agreement. All other certificates and instruments constituting
Pledged Collateral from time to time shall be delivered to the Secured Party
promptly upon the receipt thereof by or on behalf of the Debtor. All such
certificates and instruments shall be held by or on behalf of the Secured Party
pursuant hereto and shall be delivered in suitable form for transfer by
delivery or shall be accompanied by duly executed instruments of transfer or
assignment in blank, all in form and substance satisfactory to the Secured
Party.

         (b)      If the Debtor shall receive, by virtue of the Debtor's being
or having been an owner of any Pledged Collateral, any (i) stock certificate
(including, without limitation, any certificate presenting a stock dividend or
distribution in connection with any increase or reduction of capital,
reclassification, merger, consolidation, sale of assets, combination of shares,
stock split, spinoff or split-off), promissory note or other instrument, (ii)
option or right, whether as an addition to, substitution for, or in exchange
for, any Pledged Collateral, or otherwise, (iii) payment of dividends or other
distribution payable in cash (except such dividends permitted to be retained by
the Debtor pursuant to Section 6 hereof) or in securities or other property or
(iv) payment of dividends or other distribution in connection with a partial or
total liquidation or dissolution or in connection with a reduction of capital,
capital surplus or paid-in surplus, the Debtor shall receive such stock
certificate, promissory note, instrument, option, right, payment or
distribution in trust for the benefit of the Secured Party, shall segregate it
from the Debtor's other property and shall deliver it forthwith to or at the
direction of the Secured Party in the exact form received, with any necessary
indorsement and/or appropriate stock powers duly executed in blank, to be held
by or on behalf of the Secured Party as Pledged Collateral and as further
collateral security for the Obligations.

         (c)      In addition to delivering the Pledged Collateral as provided
in the foregoing clauses (a) and (b), the parties shall additionally file
Financing Statements with the State of Texas covering all of the Collateral
thereby perfecting the lien and security interest in the Collateral created by
this Agreement.

         SECTION 4. Representations, Warranties, Covenants and Agreements. The
Debtor represents and warrants to and covenants and agrees with the Secured
Party as follows:

         (a)      The Debtor is and will be at all times the legal and
beneficial owner of the Collateral free and clear of any lien, security
interest, or other charge or encumbrance, including, without limitation, any
option, except for the security interest created by this Agreement.

                                       3
<PAGE>   4

         (b)      The exercise by the Secured Party of any of Secured Party'
rights and remedies hereunder will not contravene law or any contractual
restriction binding on or affecting the Debtor or any of the Debtor's
properties and will not result in or require the creation of any lien, security
interest or other charge or encumbrance upon or with respect to any of the
Debtor's properties.

         (c)      No authorization or approval or other action by, and no
notice to or filing with, any person or entity, including, without limitation,
any governmental authority or other regulatory body, is required for (i) the
due execution, delivery and performance by the Debtor of this Agreement, (ii)
the grant by the Debtor, or the perfection, of the lien and security interest
purported to be created hereby in the Collateral or (iii) the exercise by the
Secured Party of any of Secured Party' rights and remedies hereunder, except as
may be required in connection with any sale of any Pledged Collateral by laws
affecting the offering and sale of securities generally.

         (d)      This Agreement creates a valid security interest in favor of
the Secured Party in the Collateral, as security for the Obligations. Upon
delivery of the certificates representing the Pledged Shares and all other
certificates, instruments and cash constituting Pledged Collateral from time to
time, endorsed in blank, to the Secured Party, and the filing of a financing
statement with the Secretary of State of the State of Texas in favor of the
Secured Party, naming the Debtor as "Debtor" and describing the Collateral, the
lien and security interest created herein will be a fully perfected, first
priority security interest in the Collateral. All action necessary or desirable
to perfect and protect such security interest has been duly taken, except for
the Secured Party' having possession of certificates, instruments and cash
constituting Pledged Collateral and the filing of a financing statement with
the Secretary of State of the State of Texas covering all of the Collateral
after the date hereof.

         SECTION 5. Covenants as to the Collateral. So long as any of the
Obligations shall remain outstanding, the Debtor will, unless the Secured Party
shall otherwise consent in writing:

         (a)      keep adequate records concerning the Collateral and permit
the Secured Party or any of Secured Party' agents or representatives at any
reasonable time and from time to time to examine and make copies of and
abstracts from such records;

         (b)      at the Debtor's expense, promptly deliver to the Secured
Party a copy of each notice or other communication received by it in respect of
the Collateral;

         (c)      at the Debtor's expense, defend the Secured Party' right,
title and security interest in and to the Collateral against the claims of any
person or entity;

         (d)      at Debtor's expense, at any time and from time to time,
promptly execute and deliver all further instruments and documents and take all
further action that may be necessary or desirable or that the Secured Party may
request in order to (i) perfect and protect the security interest purported to
be created hereby, (ii) enable the Secured Party to exercise and enforce
Secured Party' rights and remedies hereunder in respect of the Collateral, or

                                       4
<PAGE>   5

(iii) otherwise effect the purposes of this Agreement, including, without
limitation, delivering to or at the direction of the Secured Party, after
default, irrevocable proxies in respect of the Pledged Collateral;

         (e)      not sell, assign (by operation of law or otherwise), exchange
or otherwise dispose of any Collateral or any interest therein except as
permitted by Section 6(a)(i) hereof;

         (f)      not create or suffer to exist any lien, security interest or
other charge or encumbrance upon or with respect to any Collateral except for
the security interest created hereby;

         (g)      not make or consent to any amendment or other modification or
waiver with respect to any Collateral or enter into any agreement or permit to
exist any restriction with respect to any Collateral other than pursuant
hereto;

         (h)      not take or fail to take any action which would in any manner
impair the value or enforceability of the Secured Party' security interest in
any Collateral.

         SECTION 6. Voting Rights, Dividends, Etc. Regarding the Pledged
Collateral; Management of the Investment Account.

         (a)      So long as no demand has been made on the Note:

                  (i)      the Debtor shall be entitled to exercise any and all
voting and other consensual rights pertaining to the Pledged Collateral or any
part thereof for any purpose not inconsistent with the terms of this Agreement
or the Note; provided, however, that (A) the Debtor shall give the Secured
Party at least five (5) days written notice of the manner in which it intends
to exercise, or the reasons for refraining from exercising, any voting or other
consensual rights pertaining to the Pledged Collateral or any part thereof,
which may have a material adverse effect on the value of the Pledged Collateral
or any part thereof;

                  (ii)     the Debtor shall be entitled to receive and retain
any and all dividends or other distributions and interest paid in respect of
the Pledged Collateral; and

                  (iii)    the Debtor shall be entitled to advise Chase Bank in
the management of the Investment Account.

         (b)      After demand has been made on the Note and so long as it has
not been rescinded:

                  (i)      all rights of the Debtor to exercise the voting and
other consensual rights which the Debtor would otherwise be entitled to
exercise pursuant to paragraph (i) of subsection (a) of this Section 6, and to
receive the dividends and interest payments which the Debtor would otherwise be
authorized to receive and retain pursuant to paragraph (ii) of subsection (a)
of this Section 6, shall cease, and all such rights shall thereupon become
vested in the Secured Party which shall thereupon have the sole right to
exercise such voting and other

                                       5
<PAGE>   6

consensual rights and to receive and hold as Pledged Collateral such dividends
and interest payments;

                  (ii)     all dividends and interest payments and other
distributions which are received by the Debtor shall be received in trust for
the benefit of the Secured Party, shall be segregated from other funds of the
Debtor, and shall be forthwith paid over to the Secured Party as Pledged
Collateral in the same form as so received (with any necessary endorsement);
and

                  (iii)    the Debtor shall execute and deliver (or cause to be
executed and delivered to the Secured Party) all such proxies and other
instruments as the Secured Party may reasonably request for the purpose of
enabling the Secured Party to exercise the voting and other rights which it is
entitled to exercise pursuant to clause (i) above and to receive the dividends
or interest payments which it is entitled to receive and retain pursuant to
clause (ii) above.

                  (iv)     the Secured Party and not the Debtor shall have the
right to advise Chase Bank in the management of the Investment Account.

         (c)      So long as this Agreement and the lien and security interest
created hereby are in effect, the Debtor shall have no right to withdraw or
otherwise transfer any funds or investments out of the Investment Account
without the express written consent of the Secured Party.

         SECTION 7. Additional Provisions Concerning the Collateral.

         (a)      The Debtor hereby authorizes the Secured Party to file,
without the signature of the Debtor where permitted by law, one or more
financing or continuation statements, and amendments thereto, relating to the
Collateral.

         (b)      To the extent permitted by applicable law, the Debtor hereby
irrevocably constitutes and appoints the Secured Party, with full power of
substitution, as the Debtor's true and lawful attorney-in-fact and proxy (which
appointment as attorney-in-fact and proxy is coupled with an interest)
effective upon demand under the Note, without requiring the Secured Party to
act as such, with full authority in the place and stead of the Debtor and in
the name of the Debtor or otherwise, from time to time in the Secured Party's
discretion, to take any action and to execute any instrument which the Secured
Party may deem necessary or advisable to perfect and continue Secured Party's
lien and security interest in and to protect and preserve the Collateral and
otherwise to accomplish the purposes of this Agreement (subject to the rights
of the Debtor under Section 6(a) hereof), including, without limitation, to
receive, indorse and collect all instruments made payable to the Debtor
representing any dividend or other distribution in respect of any Pledged
Collateral and to give full discharge for the same, and to execute any
financing statement in the name of the Debtor and to file any claims or
institute any proceedings to enforce the rights of the Secured Party with
respect to the Collateral.

         (c)      If the Debtor fails to perform any agreement or obligation
contained herein, the Secured Party may perform, or cause performance of, such
agreement or obligation,

                                       6
<PAGE>   7
and the expenses of the Secured Party incurred in connection therewith shall be
payable by the Debtor pursuant to Section 9 hereof.

         (d)      The powers conferred on the Secured Party hereunder are
solely to protect the Secured Party's interest in and rights regarding the
Collateral and shall not impose any duty upon the Secured Party to exercise any
such powers. Other than the exercise of reasonable care to assure the safe
custody of the Pledged Collateral while held hereunder, the Secured Party shall
have no duty or liability as to any of the Collateral, including, without
limitation, to preserve rights pertaining thereto and shall be relieved of all
responsibility for the Pledged Collateral upon surrendering it or tendering
surrender of it to the Debtor. The Secured Party shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in Secured Party's possession if the Pledged Collateral is accorded
treatment substantially equal to that which the Secured Party accords the
Secured Party's own property, it being understood that the Secured Party shall
not have responsibility for (i) ascertaining or taking action with respect to
calls, conversions, exchanges, maturities, tenders or other matters relating to
any Pledged Collateral, whether or not the Secured Party has or is deemed to
have knowledge of such matters, or (ii) taking any necessary steps to preserve
rights against any parties with respect to any Pledged Collateral.

         (e)      The Secured Party may at any time in Secured Party's
discretion (i) without notice to the Debtor, transfer or register in the name
of the Secured Party or any of the Secured Party's nominees any or all of the
Pledged Collateral, subject only to the revocable rights of the Debtor under
Section 6(a) hereof, and (ii) exchange certificates or instruments constituting
Pledged Collateral for certificates or instruments of smaller or larger
denominations.

         SECTION 8. Remedies Upon Default. After demand has been made under the
Note and so long as it has not been rescinded:

         (a)      The Secured Party may exercise in respect of the Collateral,
in addition to other rights and remedies provided for herein or otherwise
available to the Secured Party, all of the rights and remedies of a secured
party on default under Article 9 of the Uniform Commercial Code then in effect
in the State of Texas (whether or not the Code applies to the affected
Collateral), and in addition thereto and cumulative thereof, the following
rights: the right to sell, assign or otherwise dispose of the Collateral and
without notice except as specified below, sell or otherwise transfer the
Pledged Collateral at public or private sale, at any of the Secured Party's
offices or elsewhere, for cash, on credit or for future delivery, and upon such
other terms as the Secured Party may deem commercially reasonable. In the event
that the Secured Party deems it advisable to do so, the Secured Party may (i)
restrict the bidders or purchasers of any such sale, and notwithstanding that
the Pledged Collateral may not be of a type customarily sold in a recognized
market or which is the subject of widely distributed standard price quotations,
offer the Pledged Collateral for sale to a person or entity in a private sale
at such price and on such terms as the Secured Party shall deem fair, or (ii)
the Secured Party may be the purchaser of any or all of the Pledged Collateral
so sold and may apply the purchase price therefor to reduction of any
Obligation secured hereby in any order as the Secured Party shall select. The
Debtor agrees that, to the extent that notice of sale shall be required by law,
at least ten (10) days notice to the Debtor of the time and place of any public
sale or the time after which any private sale I is to be

                                       7
<PAGE>   8

made shall constitute reasonable notification. The Secured Party shall not be
obligated to make any sale of Pledged Collateral regardless of notice of sale
having been given. The Secured Party may adjourn any public or private sale
from time to time by announcement at the time and place fixed therefor, and
such sale may, without further notice, be made at the time and place to which
it was so adjourned. Each and every method of disposition of the Pledged
Collateral described in this clause (a) shall constitute disposition of the
Pledged Collateral in a commercially reasonable manner.

         (b)      In the event that the Secured Party determine to exercise
Secured Party's right to sell all or any part of the Pledged Collateral
pursuant to subsection (a) of this Section 8, the Debtor will, at the Debtor's
expense and upon request by the Secured Party: (i) execute and deliver, and
cause each issuer of such Pledged Collateral and the directors and officers
thereof to execute and deliver, all such instruments and documents, and do or
cause to be done all such other acts and things, as may be necessary or, in the

addition to those of the Note or other evidence of liability now or hereafter
held by the Secured Party in connection with any of the Obligations, all of
which shall be construed as complementary to each other. Nothing herein
contained shall prevent the Secured Party from enforcing any or all of the
other agreements in accordance with their respective terms.

         (b)      No Waiver; Enforcement by the Secured Party, Etc. No failure
on the part of the Secured Party to exercise, and no delay in exercising, any
right hereunder, the Note or any other agreement shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right preclude

rights and remedies of the Secured Party hereunder are cumulative and
concurrent and are in addition to, and not exclusive of, any rights or remedies
provided by law or under any other agreement. The rights of the Secured Party
hereunder against the Debtor are not conditional or contingent on any attempt
by the Secured Party to exercise any of Secured Party's rights under

                                       9
<PAGE>   10

any other agreement or any other instrument or other document or against any
other person or entity.

         (c)      Notices. All notices and other communications provided for
hereunder shall be in writing (including telegraphic, telex, facsimile or cable
communication) and mailed, telegraphed, telexed, transmitted, cabled or
delivered, if to the Debtor, at the Debtor's address at 55 Waugh Drive, P.O.
Box 1343, Houston, Texas 77251; if to the Secured Party, at the Secured Party's
address at 55 Waugh Drive, P.O. Box. 1343, Houston, Texas 77251; or as to each
party at such other address as shall be designated by such party in a written
notice to the other. All such notices and other communications shall, when
mailed, telegraphed, telexed, transmitted or cabled, be effective when
deposited in the mail, delivered to the telegraph company, confirmed by telex
answer-back, transmitted by telecopier or delivered to the cable company,
respectively.

         (d)      Waiver by the Debtor. To the fullest extent permitted by
applicable law, the Debtor waives (i) protest and notice of protest of all
commercial paper at any time held by or on behalf of the Secured Party on which
the Debtor is in any way liable; (ii) notice of intention to accelerate and
notice of acceleration; and (iii) notice and opportunity to be heard, after
acceleration in the manner provided in the Note, before exercise by the Secured
Party of the remedies of self-help or set-off or of other summary procedures
permitted by any applicable law or by any agreement to which the Debtor is a
party, and, except where required hereby or by any applicable law, notice of
any other action taken by the Secured Party.

         (e)      Amendments, Etc. No amendment of any provision of this
Agreement shall be effective unless it is in writing and signed by the Debtor
and the Secured Party, and no waiver of any provision of this Agreement, and no
consent to any departure by the Debtor therefrom, shall be effective unless it
is in writing and signed by the Secured Party, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given.

         (f)      Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas, except as required
by mandatory provisions of law and except to the extent that the validity or
perfection of the pledge, assignment and security interest granted hereunder,
or remedies hereunder, in respect of any particular Collateral are governed by
the laws of a jurisdiction other than the State of Texas.

         (g)      Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining portions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction, and, to this end,
the provisions hereof are severable. Without limiting the generality of the
foregoing, in the event that any of the Obligations is unenforceable in whole
or in part in any jurisdiction, as to such jurisdiction the lien and security
interest purported to be created hereby in the Collateral shall secure the
remaining Obligations with the same effect as if such unenforceable Obligations
were never secured by such lien and security interest, and the provisions of
this Agreement shall be interpreted accordingly.

         (j)      Continuing Security Interests. This Agreement, the delivery
of the Pledged Collateral and the filing of a financing statement with the
Secretary of State of the State of Texas creates a continuing security interest

in full of the Obligations; (ii) be binding upon the Debtor, the Debtor"
successors and assigns; and (iii) inure to the benefit of and be enforceable by
the Secured Party, and the Secured Party's devisees, heirs, personal
representatives, transferees and assigns. Without limiting the generality of
the foregoing clause (iii), the Secured Party may assign or otherwise transfer
any of the Secured Party's rights under this Agreement to any other person or
entity, and to the extent of such assignment such person or entity shall
thereupon become vested with all the benefits in respect thereof granted herein
or otherwise to the Secured Party.

         (k)      Termination. At such time as the Obligations (other than any
Obligations set forth in Section 9 of which neither the Debtor nor the Secured
Party is aware) shall be fully satisfied (i) except as otherwise provided in
Section 9 hereof with respect to the Obligations of the Debtor thereunder, this
Agreement and the liens and security interests created hereby shall terminate
and all rights to the Collateral shall revert to the Debtor, and (ii) the
Secured Party will, upon the Debtor's request and at the Debtor's expense, (A)
return to the Debtor such of the Pledged Collateral as shall not have been sold
or otherwise disposed of or applied pursuant to the terms hereof, and (B)
execute and deliver to the Debtor such documents as the Debtor shall reasonably
request to evidence such termination.

enforceability of the Note or any other agreement or security document or
instrument relating thereto or executed in connection therewith; (ii) any
change in the time, manner or place of payment of, or in any other term in
respect of, all or any of the Obligations, or any amendment or waiver of or
consent to any departure from the Note or any other agreement or security
document or instrument relating thereto or executed in connection therewith,
including, without limitation, any release or amendment or waiver of or consent
to departure from any guaranty for all or any of the Obligations; (iii) any
increase in, addition to, exchange or release of, or non-perfection of any lien
on or security interest in, or other charge or encumbrance on, any of the
Collateral or any other collateral; (iv) the absence of any action on the part
of the Secured Party to obtain payment or performance of any of the Obligations
from the Debtor or any obligation of any other person or entity, or; (v) any
other event or circumstance which might otherwise constitute a release of, or a
defense available to, or a discharge of, the Debtor or any other person or

the Debtor, including any such right with respect to the Collateral, are hereby
waived by the Debtor.

         (n)      Limitation by Law. All rights, remedies and powers provided
in this Agreement may be exercised only to the extent that the exercise thereof
does not violate any applicable provision of law, and all of the provisions of
this Agreement are intended to be subject to all applicable mandatory
provisions of law which may be controlling and to be limited to the extent
necessary so that they will not render this Agreement invalid, unenforceable,
in whole or in part, or not entitled to be recorded, registered or filed under
the provisions of any applicable law.

         (o)      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which
together constitute but one and the same instrument.

         (p)      Entire Agreement. This Agreement and the Note embody the
entire agreement between the parties as to the subject matter hereof and
thereof and supersede all prior agreements and understandings relating to the
subject matter hereof and thereof. WITHOUT LIMITING THE GENERALITY OF THE
FOREGOING, THIS AGREEMENT AND THE NOTE REPRESENT THE FINAL AGREEMENT BETWEEN
THE PARTIES AS TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
