ITEM 4.  PURPOSE OF TRANSACTION

         Mr. Hamilton has acquired 224,506 shares of Common Stock pursuant to a
Combination Agreement dated as of June 6, 1997 (the "Combination Agreement")
among the Company, Carrizo Production, Inc., a Texas corporation
("Production"), Encinitas Partners Ltd., a Texas limited partnership
("Encinitas"), La Rosa Partners Ltd., a Texas limited partnership ("La Rosa"),
Carrizo Partners Ltd., a Texas limited partnership ("Carrizo Partners"), Paul
B. Loyd, Jr., Steven A. Webster, S.P. Johnson IV, Mr. Hamilton and Frank A.
Wojtek, a copy of which has been filed as Exhibit 1 hereto and is incorporated
herein by reference, and as described in the Company's Registration Statement
on Form S-1 (Reg. No. 333-29187), as amended (the "Registration Statement").
Mr. Hamilton acquired 77,175 shares and 14,610 shares of Common Stock in the
mergers of each of Production and La Rosa with the Company, respectively, in
respect of shares of common stock of Production and the limited partner
interests in La Rosa held by Mr. Hamilton.  Mr. Hamilton acquired an additional
132,721 shares of Common Stock in the acquisition of Encinitas by the Company
in respect of the limited partner interests of Encinitas held by Mr. Hamilton.
On August 11, 1997, the Company granted options for 10,000 shares of Common
Stock to Mr. Hamilton pursuant to the Company's Incentive Plan, a copy of which
has been filed as Exhibit 2 hereto and is incorporated herein by reference.
Such options are exercisable in cumulative annual increments of one-third of
the total number of shares of Common Stock subject thereto, beginning on the
first anniversary of the date of grant, at a purchase price of $11.00 per share

         Mr. Hamilton will review on a continuous basis his investment in the 
Common Stock and the Company's business affairs and financial condition, as 
well as conditions in the securities





                                     -4-
<PAGE>   5
markets and general economic and industry conditions.  Mr. Hamilton may in the
future take such actions in respect of his investment in the Common Stock as he
deems appropriate in light of the circumstances existing from time to time.
Currently, these actions include continuing to hold the shares he now
beneficially owns or disposing of shares.  Such dispositions could be effected
in private transactions, through a public offering or, upon compliance with the
rules under the Securities Act of 1933, as amended (the "Securities Act"), in
the open market.   Additionally, it is possible that Mr. Hamilton could seek to
acquire additional shares, although he has no current plans to do so, other
than through the Incentive Plan or other benefit plans or arrangements with the
Company.  Any acquisition of shares could be effected in the open market, in
privately negotiated transactions, or otherwise.  Shares may be transferred
from time to time to entities or trusts controlled by Mr. Hamilton and to
family members.  Any sales, purchases or transfers or other actions described
herein may be made at any time without further prior notice.  In reaching any
conclusion as to the foregoing matters, Mr. Hamilton may take into
consideration various factors, such as the Company's business and prospects,
other developments concerning the Company, the obligations of, cash and
financial resources and needs of, investment goals of and other business
opportunities available to him, developments with respect to his business,
general economic conditions, the market price for shares of Common Stock and
stock market conditions.

         Dispositions of the 224,506 shares of Common Stock received by Mr.
Hamilton pursuant to the Combination Agreement are restricted (subject to
certain limitations) by the Company's Bylaws, a copy of which has been filed as
Exhibit 3 hereto and is incorporated herein by reference, without the prior
written consent of the Company.  Additionally, pursuant to a Lock-up Agreement
dated July 31, 1997 of Mr. Hamilton (the "Lock-up Agreement"), a copy of which
has





                                     -5-
<PAGE>   6
been filed as Exhibit 4 hereto and is incorporated herein by reference,
delivered pursuant to the Underwriting Agreement of the Company dated August 5,
1997, Mr. Hamilton agreed not to sell (subject to certain limitations) any
shares of Common Stock until February 2, 1998 (180 days after August 6, 1997
(the date of the Prospectus of the Company (the "Prospectus") relating to the
initial public offering of shares of Common Stock (the "IPO") as described in
the Company's Registration Statement) without the prior written consent of the
underwriters for the IPO.

         Except as set forth in Item 6, Contracts, Arrangements, Understandings
or Relationships with Respect to Securities of the Issuer, Mr. Hamilton has no
present plans or proposals which relate to or would result in any of the
actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         Mr. Hamilton beneficially owns an aggregate of 1,000,796 shares of
Common Stock (approximately 10.0% of the 10,000,000 shares outstanding,
determined by reference to the approximately 10,000,000 shares of Common Stock
the Company reported in the Prospectus would be outstanding following the
consummation of the Combination Agreement and the completion of the Offering,
assuming no exercise of the underwriters' overallotment option).  Mr. Hamilton
has the sole power to vote and dispose of the shares of Common Stock
beneficially owned by him. Mr. Hamilton is among the beneficiaries of a
charitable remainder trust that is the limited partner of DAPHAM Partnership
L.P., which beneficially owns 395,960 shares of Common Stock.  See Item 6,
Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer, for a discussion of Mr. Hamilton's options.





                                     -6-
<PAGE>   7
         Except as set forth in this Schedule 13D, to the best of Mr.
Hamilton's knowledge, he has not effected any transaction in Common Stock
during the past sixty days.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER

         Except as described in this statement or in the documents referred to
herein, there are no contracts, arrangements, understandings or relationships
(legal or otherwise) between Mr. Hamilton and any person with respect to any
securities of the Company.

         The Company was formed in September 1993.  Prior to consummation of
the Combination Agreement, the Company conducted its operations directly, with
industry partners and through the following affiliated entities: Production,
Encinitas, La Rosa and Carrizo Partners.  The Company was the general partner
of Carrizo Partners and La Rosa.  Production was the general partner of
Encinitas.  On August 11, 1997, pursuant to the Combination Agreement, the
Company the following transactions were consummated:  (i) Production was merged
into the Company and the outstanding shares of capital stock of Production were
converted into an aggregate of 343,000 shares of Common Stock; (ii) the Company
acquired Encinitas in two steps: (a) the Company acquired the limited partner
interests in Encinitas held by certain of the Company's directors, including
Mr. Hamilton, for an aggregate consideration of 468,533 shares of Common Stock
and (b) Encinitas was merged into the Company, and the outstanding limited
partner interests in Encinitas were converted into an aggregate of 860,699
shares of Common Stock; (iii) La Rosa was merged into the Company and the
outstanding partnership interests in La Rosa converted into an aggregate of
48,700 shares of Common Stock; and (iv) Carrizo Partners was merged into the
Company and the outstanding partnership interests in Carrizo Partners converted
into an aggregate of 569,068 shares of Common Stock.  The closing of the
transactions under Combination Agreement occurred





                                     -7-
<PAGE>   8
simultaneously with the closing of the sale of 2,500,000 shares of Common Stock
pursuant to the Company's IPO as described in the Registration Statement.

         The current directors of the Company are S.P. Johnson IV, Frank A.
Wojtek, Steven A. Webster, Paul B. Loyd, Jr. and Mr. Hamilton.  Prior to the
consummation of the Combination Agreement, the shareholders of the Company at
such time ratified the appointment of each of such directors to the Board of
Directors of the Company by unanimous written consent.

         Pursuant to the Company's Incentive Plan, on August 11, 1997, the
Company granted options for 10,000 shares of Common Stock to Mr. Hamilton.
Such options are exercisable in cumulative annual increments of one-third of
the total number of shares of Common Stock subject thereto, beginning on the
first anniversary of the date of grant, at a purchase price of $11.00 per share
and expire ten years from the date of their issuance.  In addition, pursuant
to the Incentive Plan, if Mr. Hamilton remains a director of the Company and is
not an employee of the Company or a subsidiary of the Company, he will
automatically be granted options for 2,500 shares of Common Stock on the first
business day following the date on which each annual meeting of the Company's
shareholders is held.  Such options are exercisable in cumulative annual
increments of one-third of the total number of shares of Common Stock subject
thereto, beginning on the first anniversary of the date of grant, at a purchase
price per share equal to the fair market value of a share of Common Stock on
the date of grant and expire ten years from the date of their issuance.  Mr.
Hamilton will be deemed to be the beneficial owner of such shares 60 days prior
to the exercisability of the options related to such shares.

         The Company's Bylaws restrict the disposition of the 224,506 shares of
Common Stock received by Mr. Hamilton pursuant to the Combination Agreement
(subject to certain





                                     -8-
<PAGE>   9
limitations) without the prior written consent of the Company in order to
ensure that such dispositions are made pursuant to registration under the
Securities Act or an exemption therefrom.  The Lock-up Agreement restricts the
disposition by Mr. Hamilton of shares of Common Stock until February 2, 1998
(subject to certain limitations) without the prior written consent of the
underwriters for the Company's IPO.

         The Registration Rights Agreement dated as of June 6, 1997 among the
Company, Paul B. Loyd, Jr., Steven A.  Webster, S. P. Johnson IV, Mr. Hamilton,
Frank A. Wojtek and DAPHAM Partnership L.P. ("Registration Rights Agreement"),
a copy of which has been filed as Exhibit 5 hereto and is incorporated herein
by reference, provides registration rights with respect to shares of Common
Stock that were outstanding prior to the IPO and the issuance of shares
pursuant to the Combination Agreement, as well as shares issued pursuant to the
Combination Agreement or otherwise purchased from the Company (the "Registrable
Securities") (currently approximately 6,267,069 shares of Common Stock).
Shareholders owning not less than 51% of the then-outstanding shares of
Registrable Securities may demand that the Company effect a registration under
the Securities Act for the sale of not less than 5% of the shares of
Registrable Securities then outstanding.  The holders of the registration
rights also have limited rights to require the Company to include their shares
of Common Stock in connection with registered offerings by the Company.  The
Company may generally be required to effect three demand registrations
(provided that no such registration may occur prior to February 11, 1998 (the
date six months after the closing of the IPO)) and three additional demand
registrations for certain offerings registered on SEC Form S-3, subject to
certain conditions and limitations.  The registration rights will terminate as
to any holder of Registrable Securities at the later of (i) one year after the
closing of the IPO or (ii) at such time as





                                     -9-
<PAGE>   10
such holder may sell under Rule 144 in a three-month period all Registrable
Securities then held by such holder.  The holders of the registration rights
may not exercise their registration rights with respect to any shares received
pursuant to the Combination Agreement for a period of at least one year
following the effective date of the Registration Statement.

         Registration of shares under the Securities Act would result in such
shares becoming freely tradeable without restriction under the Securities Act
(except for shares purchased by affiliates of the Company) immediately upon the
effectiveness of such registration.

         The foregoing are summaries of certain provisions of the Combination
Agreement, the Company's Incentive Plan, the Company's Bylaws, the Lock-up
Agreement and the Registration Rights Agreement, copies of which have been
filed as Exhibits 1, 2, 3, 4 and 5, respectively, hereto and are incorporated
by reference herein; and such summaries are qualified by, and subject to, the
more complete information contained in such agreements.
