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

         Pursuant to a Stock Acquisition Agreement and Plan of Reorganization,
dated as of February 17, 1998 and amended as of April 21, 1998 (the "Stock
Acquisition Agreement"), among the Company, the Fund and 1818 Oil Corp., a
Delaware corporation and wholly-owned subsidiary of the Fund ("1818 Oil"), upon
the closing of the transactions contemplated by the Stock Acquisition Agreement
(the "Acquisition Closing"), the Company issued, and the Fund acquired from the
Company, (i) 10,000 shares of preferred stock, par value $25.00 per share (the
"Preferred Stock"), of the Company and (ii) 3,763,441 shares of Common Stock. A
copy of the Stock Acquisition Agreement and Amendment No. 1 thereto are attached
hereto as Exhibits 1 and 2 respectively and are hereby incorporated by
reference. The Fund has also entered into a Registration Rights Agreement, dated
as of April 21, 1998 (the "Registration Rights Agreement"), between the Company
and the Fund, pursuant to which the Company has agreed, under the terms and
conditions set forth therein, to register under the Securities Act of 1933, as
amended, the Common Stock issuable upon the conversion of the shares of
Preferred Stock held by the Fund and all other shares of Common Stock held by
the Fund. A copy of the Registration Rights Agreement is attached hereto as
Exhibit 3 and is hereby incorporated by reference.

         The consideration paid by the Fund for the shares of Preferred Stock it
purchased under the Stock Acquisition Agreement consisted of all of the issued
and outstanding shares of common stock, par value $.01 per share (the "1818 Oil

<PAGE>

                                                                               9

Common Stock"), of 1818 Oil and the consideration for the shares of Common Stock
it purchased under the Stock Acquisition Agreement consisted of $7,000,000 in
cash.1/

         The cash portion of the consideration (as well as the consideration the
Fund originally paid for the shares of 1818 Oil Common Stock) was obtained by
the Fund from capital contributions made by its partners pursuant to
pre-existing capital commitments.

Item 4.  Purpose of Transaction.

         The Fund has acquired the securities of the Company for investment
purposes only.

         As described below, in connection with the closing under the Stock
Acquisition Agreement, the Fund acquired certain rights and privileges with
respect to the Board of Directors and management of the Company which may impede
the acquisition of control of the Company by any person. Pursuant to the terms
of the Preferred Stock, all of the outstanding shares of which are held by the
Fund, for so long as the number of outstanding shares of Preferred Stock
represent (after giving effect to any adjustments) on a fully-diluted basis at
least five percent (5%) of the

<PAGE>

                                                                              10

total number of shares of Common Stock outstanding, the holders of the Preferred
Stock have the right to elect three members of the Board of Directors of the
Company. As of the Acquisition Closing, the number of members of the Board of
Directors was increased from five to eight to allow the Fund, as holder of all
of the outstanding shares of Preferred Stock, to designate three individuals to
be directors of the Company, and such individuals have been elected to the Board
of Directors. In addition, the holders of shares of Preferred Stock vote
together with the holders of shares of Common Stock on all matters submitted to
the holders of Common Stock at any annual or special meeting of the Company (or
any written consent in lieu thereof), including the election of directors.
Accordingly, as described in Item 5 below, as of the date hereof the combined
voting power of the shares of Common Stock and the shares of Preferred Stock
held by the Fund would allow the Fund to control any vote submitted to the
shareholders of the Company (or any written consent in lieu thereof) which
requires the consent of a majority of holders of shares of Common Stock. A copy
of the Certificate of Designation of the Preferred Stock is attached hereto as
Exhibit 4 and is hereby incorporated by reference.

         Pursuant to the terms of the Stock Acquisition Agreement, the By-Laws
of the Company were amended as of the Acquisition Closing to provide that the
consent of at least one director elected by the class vote of the holders of
shares of Preferred Stock is required for the Board of Directors to approve
certain actions by the Company, including, without limitation, (i) the issuance
of any equity securities of the Company or any subsidiary thereof, or rights of
any kind convertible or exchangeable for any equity securities of the Company or
any subsidiary thereof, or

<PAGE>

                                                                              11

any option, warrant or other subscription or purchase right with respect to
equity securities of the Company or any subsidiary thereof; (ii) any transaction
of merger or consolidation of the Company or any subsidiary thereof with one or
more persons or any transaction of merger or consolidation of one or more
persons into or with the Company or any subsidiary thereof; (iii) any sale,
conveyance, exchange or transfer to another person of (x) the voting stock of
the Company or any subsidiary thereof or (y) all or substantially all of the
assets of the Company or any subsidiary thereof, (iv) outside of the ordinary
course of business (x) any sale, conveyance, exchange, transfer or lease or
other disposition to another person of any material assets, rights or properties
of the Company or any subsidiary thereof or (y) any purchase, lease or other
acquisition of any material assets, rights or properties of another person; (v)
any amendment, modification or restatement of the Restated Certification of
Incorporation or By-Laws of the Company, or the certificate of incorporation of
any subsidiary of the Company (including, without limitation, a change in the
number of directors which constitutes the Board of Directors).

         The Company has informed the Fund that, as a result of the closing
under the Stock Acquisition Agreement and a separate private placement of shares
of Common Stock, the Company currently does not have reserved and available for
issuance such number of authorized but unissued shares of Common Stock as would

<PAGE>

                                                                              12

be sufficient to permit the conversion of all of the outstanding shares of
Preferred Stock and all outstanding warrants and options with respect to the
Common Stock (collectively, the "Options") into shares of Common Stock. Pursuant
to a letter agreement, dated as of April 21, 1998 (the "Letter Agreement"),
among the Company, the Fund, Robert L. Gerry ("Gerry") and W. Russell Scheirman
("Scheirman"), the Fund, Gerry and Scheirman (i) waived any breach by the
Company of the terms of the Preferred Stock and Options held by each of them as
a result of there not being a sufficient amount of Common Stock available for
issuance upon the conversion or exercise of such securities; (ii) agreed not to
convert a certain number of shares of Preferred Stock and Options held by each
of them so that the Company would not be in breach of its obligations to other
persons with respect to the Company's having a sufficient amount of authorized
but unissued shares of Common Stock to allow for the conversion into Common
Stock of all of the Options held by such other persons; and (iii) agreed to vote
in favor of an amendment to the Restated Certificate of Incorporation of the
Company to allow the Company to have reserved and available for issuance such
number of shares of Common Stock as would be sufficient to allow for the
conversion of all outstanding shares of Preferred Stock and all outstanding
Options. A copy of the Letter Agreement is attached hereto as Exhibit 5 and is
hereby incorporated by reference.

         The Reporting Persons may from time to time acquire additional shares
of Common Stock in the open market or in privately negotiated transactions,
subject to the availability of shares of Common Stock at prices deemed
favorable, the Company's business or financial condition and to other factors
and conditions the

<PAGE>

                                                                              13
Reporting Persons deem appropriate. Alternatively, the Reporting Persons may
sell all or a portion of the shares of Common Stock or Preferred Stock in open
market or in privately negotiated transactions, subject to the factors and
conditions referred to above and compliance with applicable laws.

         Except as described in the Registration Rights Agreement and the Letter
Agreement and as set forth above in this Item 4, no Reporting Person has any
present plans or proposals which relate to or would result in: (a) the
acquisition by any person of additional securities of the issuer, or the
disposition of securities of the issuer; (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Company or any of its subsidiaries; (c) a sale or transfer of a material amount

Item 5.  Interest in Securities of the Issuer.

         (a) through (c). As set forth above, in connection with the closing
under the Stock Acquisition Agreement the Fund acquired 10,000 shares of
Preferred Stock and 3,763,441 shares of Common Stock. Accordingly, as of April
27, 1998, assuming the conversion of the shares of Preferred Stock held by the
Fund into shares of Common Stock as of such date, the Fund may be deemed to own
31,263,441 shares of Common Stock, which, based on calculations made in
accordance with Rule 13-d3(d) promulgated under the Securities Exchange Act of
1934, as amended, and there being 16,986,527 shares of Common Stock outstanding
on April 27, 1998 (as represented to the Fund by the Company), represents 70.27%
of the outstanding shares of Common Stock.

         By virtue of BBH&Co.'s relationship with the Fund, BBH&Co. may be
deemed to beneficially own 31,263,441 shares of Common Stock, representing
approximately 70.27% of the outstanding shares of Common Stock (based on the

the Company to the Fund). By virtue of the resolution adopted by BBH&Co.
designating Long and Tucker, or either of them, as the sole and exclusive
partners of BBH&Co. having voting power (including the power to vote or to
direct the voting) and investment power (including the power to dispose or to
direct the disposition) with respect to the securities of the Company, each of
Long and Tucker may be deemed to beneficially own 33,263,441 shares of Common
Stock, representing approximately 70.27% of the outstanding shares of Common
Stock (based on the

shares of Common Stock during the proceeding 60 days.

         REGISTRATION RIGHTS AGREEMENT, dated April 21, 1998, between VAALCO
ENERGY, INC., a Delaware corporation (the "Company"), and THE 1818 FUND II,
L.P., a Delaware limited partnership (the "Purchaser").

         1. Background. Pursuant to a Stock Acquisition Agreement and Plan of
Reorganization, dated February 17, 1998 (the "Purchase Agreement"), among the
Company, the Purchaser and 1818 Oil Corp., a Delaware corporation, the Purchaser
has agreed to purchase from the Company, and the Company has agreed to issue to
the Purchaser (i) an aggregate of 10,000 shares of preferred stock, par value
$25.00 per share (the "Preferred Stock"), of the Company and (ii) an aggregate
of 3,763,441 shares of common stock, par value $.01 per share (the "Common
Stock"), of the Company. Capitalized terms used herein but not otherwise defined
shall have the meanings given them in Section 3.

         2. Registration Under Securities Act, etc.

                 2.1 Registration on Request.

                           (a) Request. At any time, or from time to time, one
or more holders (the "Initiating Holders") of not less than 20% of the Purchaser
Stock may, upon written request, require the Company to effect the registration
under the Securities Act of any Registrable Securities held by such Initiating
Holders. The Company promptly will give written notice of such requested
registration to all other holders of Registrable Securities who may join in such
registration, and thereupon the Company will use its best efforts to effect, at
the earliest possible date, the registration under the Securities Act

                                    (i) the Registrable Securities that the
         Company has been so requested to register by such Initiating Holders,
         and

                                    (ii) all other Registrable Securities that
         the Company has been requested to register by the holders thereof (such
         holders together with the Initiating Holders hereinafter are referred
         to as the "Selling Holders") by written request given to the Company
         within 30 days after the giving of such written notice by the Company,
         all to the extent requisite to permit the disposition of the
         Registrable Securities so to be registered.

                           (b) Registration of Other Securities. Whenever the
Company shall effect a registration pursuant to this Section 2.1, no securities
other than Registrable Securities shall be included among the securities covered
by such registration unless (subject to Section 2.1(f)) the Selling Holders of
not less than 51% of all Registrable Securities to be covered by such
registration shall have consented in writing to the inclusion of such other
securities.

<PAGE>

                                                                               2

                           (c) Registration Statement Form. Registrations under
this Section 2.1 shall be on such appropriate registration form of the
Commission as shall be reasonably selected by the Company.

                           (d) Effective Registration Statement. A registration
requested pursuant to this Section 2.1 shall not be deemed to have been effected
(i) unless a registration statement with respect thereto has become effective
and remained effective in compliance with the provisions of the Securities Act
with respect to the disposition of all Registrable Securities covered by such
registration statement until the earlier of (x) such time as all of such
Registrable Securities have been disposed of in accordance with the intended
methods of disposition by the seller or sellers thereof set forth in such
registration statement and (y) 180 days after the effective date of such
registration statement, except with respect to any registration statement filed
pursuant to Rule 415 under the Securities Act, in which case the Company shall
use its best efforts to keep such registration statement effective until such
time as all of the Registrable Securities cease to be Registrable Securities,
(ii) if after it has become effective, such registration is interfered with by
any stop order, injunction or other order or requirement of the Commission or
other governmental agency or court for any reason not attributable to the
Selling Holders and has not thereafter become effective, or (iii) if the
conditions to closing specified in the underwriting agreement, if any, entered
into in connection with such registration are not satisfied or waived, other
than solely by reason of a failure on the part of the Selling Holders.

                           (e) Selection of Underwriters. The underwriter or
underwriters of each underwritten offering of the Registrable Securities so to
be registered shall be selected by the Selling Holders of more than 50% of the
Registrable Securities to be included in such registration and shall be
reasonably acceptable to the Company.

                           (f) Priority in Requested Registration. If the
managing underwriter of any underwritten offering shall advise the Company in
writing (and the Company shall so advise each Selling Holder of Registrable
Securities requesting registration of such advice) that, in its opinion, the
number of securities requested to be included in such registration exceeds the
number that can be sold in such offering within a price range acceptable to the
Selling Holders of 66-2/3% of the Registrable Securities requested to be
included in such registration, the Company, except as provided in the following
sentence, will include in such registration, to the extent of the number and
type that the Company is so advised can be sold in such offering, Registrable
Securities requested to be included in such registration, pro rata among the
Selling Holders requesting such registration on the basis of the estimated gross
proceeds from the sale thereof. If the total number of Registrable Securities
requested to be included in such registration cannot be included as provided in
the preceding sentence, holders of Registrable Securities requesting
registration thereof pursuant to Section 2.1, representing not less than 33-1/3%
of the Registrable Securities with respect to which registration has been
requested and

<PAGE>

                                                                               3

constituting not less than 66-2/3% of the Initiating Holders, shall have the
right to withdraw the request for registration by giving written notice to the
Company within 20 days after receipt of such notice by the Company and, in the
event of such withdrawal, such request shall not be counted for purposes of the
requests for registration to which holders of Registrable Securities are
entitled pursuant to Section 2.1 hereof. In connection with any such
registration to which this Section 2.1(f) is applicable, no securities other
than Registrable Securities shall be covered by such registration.

                           (g) Limitations on Registration on Request.
Notwithstanding anything in this Section 2.1 to the contrary, in no event will
the Company be required to effect, in the aggregate, more than three
registrations pursuant to this Section 2.1.

                           (h) Expenses. The Company will pay all Registration
Expenses in connection with any registration requested pursuant to this Section
2.1.

                 2.2 Incidental Registration.

                           (a) Right to Include Registrable Securities. If the
Company at any time proposes to register any shares of Common Stock or any
securities convertible into Common Stock under the Securities Act by
registration on any form other than Forms S-4 or S-8, whether or not for sale
for its own account, it will each such time give prompt written notice to all
registered holders of Registrable Securities of its intention to do so and of
such holders' rights under this Section 2.2. Upon the written request of any
such holder (a "Requesting Holder") made as promptly as practicable and in any
event within 15 days after the receipt of any such notice, the Company will use
its best efforts to effect the registration under the Securities Act of all
Registrable Securities that the Company has been so requested to register by the
Requesting Holders thereof; provided, however, that prior to the effective date
of the registration statement filed in connection with such registration,
immediately upon notification to the Company from the managing underwriter of
the price at which such securities are to be sold, if such price is below the
price that any Requesting Holder shall have indicated to be acceptable to such
Requesting Holder, the Company shall so advise such Requesting Holder of such
price, and such Requesting Holder shall then have the right to withdraw its
request to have its Registrable Securities included in such registration
statement; provided further, that if, at any time after giving written notice of
its intention to register any securities and prior to the effective date of the
registration statement filed in connection with such registration, the Company
shall determine for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to each Requesting Holder of Registrable Securities and (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from any obligation of the Company to pay the Registration Expenses in
connection therewith), without prejudice, however, to the rights of any holder
or holders of

<PAGE>

                                                                               4

Registrable Securities entitled to do so to cause such registration to be
effected as a registration under Section 2.1, and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities, for the same period as the delay in registering such
other securities. Notwithstanding anything contained in this Section 2.2(a), the
Company shall not, if any Requesting Holder shall have requested the
registration of shares of Common Stock issuable upon conversion of any Preferred
Stock, consummate the sale of the securities included in the registration until
such time as any applicable waiting period under the Hart-Scott- Rodino Act
shall have expired or early termination thereunder shall have been granted if
such Requesting Holder notifies the Company that it is required to make a filing
under the Hart-Scott-Rodino Act before it may convert its Preferred Stock. No
registration effected under this Section 2.2 shall relieve the Company of its
obligation to effect any registration upon request under Section 2.1.

                           (b) Priority in Incidental Registrations. If the
managing underwriter of any underwritten offering shall inform the Company by
letter of its opinion that the number or type of Registrable Securities
requested to be included in such registration would materially adversely affect
such offering, and the Company has so advised the Requesting Holders in writing,
then the Company will include in such registration, to the extent of the number
and type that the Company is so advised can be sold in (or during the time of)
such offering, first, all securities proposed by the Company to be sold for its
own account and second, all other securities proposed to be registered pro rata
on the basis of the estimated proceeds from the sale thereof.

                           (c) Expenses. The Company will pay all Registration
Expenses in connection with any registration effected pursuant to this Section
2.2.

                 2.3 Registration Procedures. If and whenever the Company is
required to effect the registration of any Registrable Securities under the
Securities Act as provided in Sections 2.1 and 2.2, the Company will, as
expeditiously as possible:

                           (i) prepare and (within 90 days after the end of the
         period within which requests for registration may be given to the
         Company or in any event as soon thereafter as practicable) file with
         the Commission the requisite registration statement to effect such
         registration and thereafter use its best efforts to cause such
         registration statement to become effective; provided, however, that the
         Company may discontinue any registration of its securities that are not
         Registrable Securities (and, under the circumstances specified in
         Sections 2.2(a) or 2.6, if applicable, its securities that are
         Registrable Securities) at any time prior to the effective date of the
         registration statement relating thereto;

                           (ii) prepare and file with the Commission such
         amendments and supplements to such registration statement and the
         prospectus

<PAGE>

                                                                               5

         used in connection therewith as may be necessary to keep such
         registration statement effective and to comply with the provisions of
         the Securities Act with respect to the disposition of all Registrable
         Securities covered by such registration statement until the earlier of
         (a) such time as all of such Registrable Securities have been disposed
         of in accordance with the intended methods of disposition by the seller
         or sellers thereof set forth in such registration statement and (b) 180
         days after the effective date of such registration statement, except
         with respect to any registration statement filed pursuant to Rule 415
         under the Securities Act if the Company is eligible to file a
         registration statement on Form S-3, in which case the Company shall use
         its best efforts to keep the registration statement effective and
         updated, from the date such registration statement is declared
         effective until such time as all of the Registrable Securities cease to
         be Registerable Securities;

                           (iii) furnish to each seller of Registrable
         Securities covered by such registration statement, such number of
         conformed copies of such registration statement and of each such
         amendment and supplement thereto (in each case including all exhibits),
         such number of copies of the prospectus contained in such registration
         statement (including each preliminary prospectus and any summary
         prospectus) and any other prospectus filed under Rule 424 under the
         Securities Act, in conformity with the requirements of the Securities
         Act, and such other documents, as such seller may reasonably request;

                           (iv) use its best efforts (x) to register or qualify
         all Registrable Securities and other securities covered by such
         registration statement under such other securities or blue sky laws of
         such States of the United States of America where an exemption is not
         available and as the sellers of Registrable Securities covered by such
         registration statement shall reasonably request, (y) to keep such
         registration or qualification in effect for so long as such
         registration statement remains in effect and (z) to take any other
         action that may be reasonably necessary or advisable to enable such
         sellers to consummate the disposition in such jurisdictions of the
         securities to be sold by such sellers, except that the Company shall
         not for any such purpose be required to qualify generally to do
         business as a foreign corporation in any jurisdiction wherein it would
         not but for the requirements of this subdivision (iv) be obligated to
         be so qualified or to consent to general service of process in any such
         jurisdiction;

                           (v) use its best efforts to cause all Registrable
         Securities covered by such registration statement to be registered with
         or approved by such other federal or state governmental agencies or
         authorities as may be necessary in the opinion of counsel to the
         Company and counsel to the seller or sellers of Registrable Securities
         to enable the seller or sellers thereof to consummate the disposition
         of such Registrable Securities;

                           (vi) in the case of an underwritten or "best efforts"
         offering, furnish at the effective date of such registration statement
         to each seller of Registrable Securities, and each such seller's
         underwriters, if any, a signed counterpart of:

                                    (x) an opinion of counsel for the Company,
                  dated the effective date of such registration statement and,
                  if applicable, the date of the closing under the underwriting
                  agreement, and

                                    (y) a "comfort" letter signed by the

                  Company's financial statements included or incorporated by
                  reference in such registration statement,

         covering substantially the same matters with respect to such
         registration statement (and the prospectus included therein) and, in
         the case of the accountants' comfort letter, with respect to events
         subsequent to the date of such financial statements, as are customarily
         covered in opinions of issuer's counsel and in accountants' comfort
         letters delivered to the underwriters in underwritten public offerings
         of securities and, in the case of the accountants' comfort letter, such
         other financial matters, and, in the case of the legal opinion, such
         other legal matters, as the underwriters may reasonably request;

                           (vii) cause representatives of the Company to
         participate in any "road show" or "road shows" reasonably requested by
         any underwriter of an underwritten or "best efforts" offering of any
         Registrable Securities;

                           (viii) notify each seller of Registrable Securities
         covered by such registration statement at any time when a prospectus
         relating thereto is required to be delivered under the Securities Act,
         upon discovery that, or upon the happening of any event as a result of
         which, the prospectus included in such registration statement, as then
         in effect, includes an untrue statement of a material fact or omits to
         state any material fact required to be stated therein or necessary to
         make the statements therein not misleading, in the light of the
         circumstances under which they were made, and at the request of any
         such seller promptly prepare and furnish to it a reasonable number of
         copies of a supplement to or an amendment of such prospectus as may be
         necessary so that, as thereafter delivered to the purchasers of such
         securities, such prospectus shall not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         the light of the circumstances under which they were made;

                           (ix) otherwise use its best efforts to comply with
         all applicable rules and regulations of the Commission, and make
         available to its

<PAGE>

                                                                               7

                  security holders, as soon as reasonably practicable, an
                  earnings statement covering the period of at least twelve
                  months, but not more than eighteen months, beginning with the
                  first full calendar month after the effective date of such
                  registration statement, which earnings statement shall satisfy
                  the provisions of Section 11(a) of the Securities Act and Rule
                  158 promulgated thereunder, and promptly furnish to each such
                  seller of Registrable Securities a copy of any amendment or
                  supplement to such registration statement or prospectus;

                           (x) provide and cause to be maintained a transfer
                  agent and registrar (which, in each case, may be the Company)
                  for all Registrable Securities covered by such registration
                  statement from and after a date not later than the effective
                  date of such registration; and

                           (xi) if any class of securities of the Company is
                  listed on any national securities exchange or automated
                  quotation system at the time of the effectiveness of any
                  registration statement, the Company shall use its best efforts
                  to list all Registrable Securities covered by such
                  registration statement on such national securities exchange or
                  automated quotation system.

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish the Company in a reasonably prompt
manner such information regarding such seller and the distribution of such
securities as the Company may from time to time reasonably request in writing;
provided, that any such information shall be given or made by a seller of
Registrable Securities without representation or warranty of any kind whatsoever
except representations with respect to the identity of such seller, such
seller's Registrable Securities and such seller's intended method of
distribution or any other representations required by applicable law.

         Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in subdivision (viii) of this
Section 2.3, such holder will forthwith discontinue such holder's disposition of
Registrable Securities pursuant to the registration statement relating to such
Registrable Securities until such holder's receipt of the copies of the
supplemented or amended prospectus contemplated by subdivision (viii) of this
Section 2.3 and, if so directed by the Company, will deliver to the Company (at
the Company's expense) all copies, other than permanent file copies, then in
such holder's possession of the prospectus relating to such Registrable
Securities current at the time of receipt of such notice.

                 2.4 Underwritten Offerings.

                           (a) Requested Underwritten Offerings. If requested by
the underwriters for any underwritten offering by holders of Registrable
Securities pursuant to a registration requested under Section 2.1, the Company
will use its best

<PAGE>

                                                                               8

efforts to enter into an underwriting agreement with such underwriters for such
offering, such agreement to be reasonably satisfactory in substance and form to
each such holder of Registrable Securities and the underwriters and to contain
such representations and warranties by the Company and such other terms as are
generally prevailing in agreements of that type, including, without limitation,
indemnities to the effect and to the extent provided in Section 2.7. The holders
of the Registrable Securities proposed to be sold by such underwriters will
reasonably cooperate with the Company in the negotiation of the underwriting
agreement. Such holders of Registrable Securities to be sold by such
underwriters shall be parties to such underwriting agreement and may, at their
option, require that any or all of the representations and warranties by, and
the other agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of such holders of
Registrable Securities and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to the obligations of such holders of Registrable Securities. No
holder of Registrable Securities shall be required to make any representations
or warranties to, or agreements with, the Company other than representations or
warranties regarding the identity of such holder, such holder's Registrable
Securities and such holder's intended method of distribution or any other
representations required by applicable law.

                           (b) Incidental Underwritten Offerings. If the Company
proposes to register any of its securities under the Securities Act as
contemplated by Section 2.2 and such securities are to be distributed by or
through one or more underwriters, the Company will, if requested by any
Requesting Holder of Registrable Securities, use its best efforts to arrange for
such underwriters to include all the Registrable Securities to be offered and
sold by such Requesting Holder among the securities of the Company to be
distributed by such underwriters, subject to the provisions of Section 2.2(b).
The holders of Registrable Securities to be distributed by such underwriters
shall be parties to the underwriting agreement between the Company and such
underwriters and may, at their option, require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of such holders of Registrable Securities and that any or all of
the conditions precedent to the obligations of such underwriters under such
underwriting agreement be conditions precedent to the obligations of such
holders of Registrable Securities. Any such Requesting Holder of Registrable
Securities shall not be required to make any representations or warranties to or
agreements with the Company or the underwriters other than representations or
warranties regarding the identity of such Requesting Holder, such Requesting
Holder's Registrable Securities and such Requesting Holder's intended method of
distribution or any other representations required by applicable law.

                           (c) Underwriting Discounts and Commission. The
holders of Registrable Securities sold in any offering pursuant to Section
2.4(a) or

<PAGE>

                                                                               9

Section 2.4(b) shall pay all underwriting discounts and commissions of the
underwriter or underwriters with respect to the Registrable Securities sold
thereby.

                 2.5 Preparation; Reasonable Investigation. In connection with
the preparation and filing of each registration statement under the Securities
Act pursuant to this Agreement, the Company will give the holders of Registrable
Securities registered under such registration statement, the underwriters, if
any, and their respective counsel the opportunity to participate in the
preparation of such registration statement, each prospectus included therein or
filed with the Commission, and each amendment thereof or supplement thereto, and
will give each of them such reasonable access to its books and records and such
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of such holders' and such underwriters'
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

                 2.6 Limitations, Conditions and Qualifications to Obligations
under Registration Covenants. The Company shall be entitled to postpone for a
reasonable period of time (but not exceeding 90 days) the filing of any
registration statement otherwise required to be prepared and filed by it
pursuant to Section 2.1 if the Company determines, in its good faith judgment,
that such registration and offering would interfere with any material financing,
acquisition, corporate reorganization or other material transaction involving
the Company or any of its affiliates and promptly gives the holders of
Registrable Securities requesting registration thereof pursuant to Section 2.1
written notice of such determination, containing a general statement of the
reasons for such postponement and an approximation of the anticipated delay. If
the Company shall so postpone the filing of a registration statement, holders of
Registrable Securities requesting registration thereof pursuant to Section 2.1,
representing not less than 33-1/3% of the Registrable Securities with respect to
which registration has been requested and constituting not less than 66-2/3% 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
request shall not be counted for purposes of the requests for registration to
which holders of Registrable Securities are entitled pursuant to Section 2.1
hereof.

                 2.7 Indemnification.

                           (a) Indemnification by the Company. The Company will,
and hereby does, indemnify and hold harmless, in the case of any registration
statement filed pursuant to Section 2.1 or 2.2, each seller of any Registrable
Securities covered by such registration statement and each other Person who
participates as an underwriter in the offering or sale of such securities and
each other Person, if any, who controls such seller or any such underwriter
within the meaning of the Securities Act, and their respective directors,
officers, partners, members, agents and affiliates against any losses, claims,
damages or liabilities, joint or several,

<PAGE>

                                                                              10

to which such seller or underwriter or any such director, officer, partner,
member, agent, affiliate or controlling person may become subject under the
Securities Act or otherwise, including, without limitation, the fees and
expenses of legal counsel (including those incurred in connection with any claim
for indemnity hereunder), insofar as such losses, claims, damages or liabilities
(or actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein in light of the circumstances in which they were made not misleading,
and the Company will reimburse such seller or underwriter and each such
director, officer, partner, member, agent, affiliate and controlling Person for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such seller or underwriter, as the case may be, specifically stating that it is
for use in the preparation thereof; and provided, further, that the Company
shall not be liable to any Person who participates as an underwriter in the
offering or sale of Registrable Securities or any other Person, if any, who
controls such underwriter within the meaning of the Securities Act, in any such
case to the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of such Person's failure to
send or give a copy of the final prospectus, as the same may be then
supplemented or amended, to the Person asserting an untrue statement or alleged
untrue statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such Person if such
statement or omission was corrected in such final prospectus. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of such seller or any such director, officer, partner, member, agent
or controlling person and shall survive the transfer of such securities by such
seller.

                           (b) Indemnification by the Sellers. As a condition to
including any Registrable Securities in any registration statement, the Company
shall have received an undertaking satisfactory to it from the prospective
seller of such Registrable Securities, to indemnify and hold harmless (in the
same manner and to the same extent as set forth in Section 2.7(a)) the Company,
and each director of the Company, each officer of the Company and each other
Person, if any, who participates as an underwriter in the offering or sale of
such securities and each other Person who controls the Company or any such
underwriter within the meaning of the

<PAGE>

                                                                              11

Securities Act, with respect to any statement or alleged statement in or
omission or alleged omission from such registration statement, any preliminary
prospectus, final prospectus or summary prospectus contained therein, or any
amendment or supplement thereto, if such statement or alleged statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by such seller specifically stating
that it is for use in the preparation of such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement; provided, however, that the liability of such indemnifying party
under this Section 2.7(b) shall be limited to the amount of the net proceeds
received by such indemnifying party in the offering giving rise to such
liability. Such indemnity shall remain in full force and effect, regardless of
any investigation made by or on behalf of the Company or any such director,
officer or controlling person and shall survive the transfer of such securities
by such seller.

                           (c) Notices of Claims, etc. Promptly after receipt by
an indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in Section 2.7(a) or (b), such indemnified party
will, if a claim in respect thereof is to be made against an indemnifying party,
give written notice to the latter of the commencement of such action; provided,
however, that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligations under the
preceding subdivisions of this Section 2.7, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice. In
case any such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it may
wish, to assume the defense thereof, with counsel reasonably satis factory to
such indemnified party; provided, however, that any indemnified party may, at
its own expense, retain separate counsel to participate in such defense.
Notwithstanding the foregoing, in any action or proceeding in which both the
Company and an indemnified party is, or is reasonably likely to become, a party,
such indemnified party shall have the right to employ separate counsel at the
Company's expense and to control its own defense of such action or proceeding
if, in the reasonable opinion of counsel to such indemnified party, (a) there
are or may be legal defenses available to such indemnified party or to other
indemnified parties that are different from or additional to those available to
the Company or (b) any conflict or potential conflict exists between the Company
and such indemnified party that would make such separate representation
advisable; provided, however, that in no event shall the Company be required to
pay fees and expenses under this Section 2.7 for more than one firm of attorneys
in any jurisdiction in any one legal action or group of related legal actions.
No indemnifying party shall be liable for any settle ment of any action or
proceeding effected without its written consent, which consent shall not be
unreasonably withheld. No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability
in respect

<PAGE>

                                                                              12

to such claim or litigation or which requires action other than the payment of
money by the indemnifying party.

                           (d) Contribution. If the indemnification provided for
in this Section 2.7 shall for any reason be held by a court to be unavailable to
an indemnified party under Section 2.7(a) or (b) hereof in respect of any loss,
claim, damage or liability, or any action in respect thereof, then, in lieu of
the amount paid or payable under Section 2.7(a) or (b), the indemnified party
and the indemnifying party under Section 2.7(a) or (b) shall contribute to the
aggregate losses, claims, damages and liabilities (including legal or other
expenses reasonably incurred in connection with investigating the same,
including those incurred in connection with any claim for indemnity hereunder),
(i) in such proportion as is appropriate to reflect the relative fault of the
Company and the prospective sellers of Registrable Securities covered by the
registration statement which resulted in such loss, claim, damage or liability,
or action or proceeding in respect thereof, with respect to the statements or
omissions which resulted in such loss, claim, damage or liability, or action or
proceeding in respect thereof, as well as any other relevant equitable
considerations or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as shall be appropriate to
reflect the relative benefits received by the Company and such prospective
sellers from the offering of the securities covered by such registration
statement; provided, however, that for purposes of this clause (ii), the
relative benefits received by the prospective sellers shall be deemed not to
exceed the amount of proceeds received by such prospective sellers. No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation. Such prospective sellers'
obligations to contribute as provided in this Section 2.7(d) are several in
proportion to the relative value of their respective Registrable Securities
covered by such registration statement and not joint. In addition, no Person
shall be obligated to contribute hereunder any amounts in payment for any
settlement of any action or claim effected without such Person's consent, which
consent shall not be unreasonably withheld.

                           (e) Other Indemnification. Indemnification and
contribution similar to that specified in the preceding subdivisions of this
Section 2.7 (with appropriate modifications) shall be given by the Company and
each seller of Registrable Securities with respect to any required registration
or other qualification of securities under any federal or state law or
regulation of any governmental authority other than the Securities Act.

                           (f) Indemnification Payments. The indemnification and
contribution required by this Section 2.7 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 is incurred.

                 3. Definitions. As used herein, unless the context otherwise

foregoing, in the event the Company shall determine, in accordance with Section
2.2(a) or Section 2.6, not to register any securities with respect to which it

Registrable Securities, all of the costs of the type (and subject to any

Preferred Stock (or shares of Common Stock issued or issuable upon conversion of
the Preferred Stock) and Common Stock, any securities of the Company or any
other Person which are issued or issuable in respect of, or in exchange for,

particular section of the Securities Act of 1933, as amended, shall include a
reference to the comparable section, if any, of any such similar Federal
statute.

                 4. Rule 144 and Rule 144A. The Company shall take all actions
reasonably necessary to enable holders of Registrable Securities to sell such
securities without registration under the Securities Act within the limitation
of the provisions of (a) Rule 144 under the Securities Act, as such Rule may be
amended from time to time, (b) Rule 144A under the Securities Act, as such Rule

Registrable Securities, the Company will deliver to such holder a written
statement as to whether it has complied with such requirements.

                 5. Amendments and Waivers. This Agreement may be amended with
the consent of the Company and the Company may take any action herein

Registrable Securities at the time or thereafter outstanding shall be bound by
any consent authorized by this Section 5, whether or not such Registrable
Securities shall have been marked to indicate such consent.

                 6. Nominees for Beneficial Owners. In the event that any
Registrable Securities are held by a nominee for the beneficial owner thereof,
the beneficial owner thereof may, at its election in writing delivered to the
Company, be treated as the holder of such Registrable Securities for purposes of
any request or other action by any holder or holders of Registrable Securities
pursuant to this Agreement or any determination of any number or percentage of
shares of Registrable Securities held by any holder or holders of Registrable
Securities contemplated by this Agreement. If the beneficial owner of any
Registrable Securities so elects, the Company may require assurances reasonably
satisfactory to it of such owner's beneficial ownership of such Registrable
Securities.

                 7. Notices. All notices, demands and other communications
provided for or permitted hereunder shall be made in writing and shall be by
registered or certified first-class mail, return receipt requested, telecopier,
courier service or personal delivery:

                           (a) if to the Purchaser, addressed to it in the
manner set forth in the Purchase Agreement, or at such other address as the
Purchasers shall have furnished to the Company in writing in the manner set
forth herein;

                           (b) if to any other holder of Registrable Securities,
at the address that such holder shall have furnished to the Company in writing
in the manner set forth herein, or, until any such other holder so furnishes to
the Company an address, then to and at the address of the last holder of such
Registrable Securities who has furnished an address to the Company; or

                           (c) if to the Company, addressed to it in the manner
set forth in the Purchase Agreement, or at such other address as the Company
shall have furnished to each holder of Registrable Securities at the time
outstanding in the manner set forth herein.

         All such notices and communications shall be deemed to have been duly
given: when delivered by hand, if personally delivered; when delivered to a
courier, if delivered by overnight courier service; five Business Days after
being deposited in the mail, postage prepaid, if mailed; and when receipt is
acknowledged, if telecopied.

                 8. Assignment. This Agreement shall be binding upon and inure
to the benefit of and be enforceable by the parties hereto and, with respect to
the Company, its respective successors and permitted assigns and, with respect
to the Purchasers, any holder of any Registrable Securities, subject to the
provisions respecting the minimum numbers of percentages of shares of
Registrable Securities

<PAGE>

                                                                              16

required in order to be entitled to certain rights, or take certain actions,
contained herein. Except by operation of law, this Agreement may not be assigned
by the Company without the prior written consent of the holders of a majority in
interest of the Registrable Securities outstanding at the time such consent is
requested.

                 9. Calculation of Percentage Interests in Registrable
Securities. For purposes of this Agreement, all references to a percentage of
the Registrable Securities shall be calculated based upon the number of shares
of Registrable Securities outstanding at the time such calculation is made,
assuming the conversion of all the outstanding Preferred Stock.

                 10. No Inconsistent Agreements. The Company will not hereafter
enter into any agreement with respect to its securities that is inconsistent
with the rights granted to the holders of Registrable Securities in this
Agreement. Without limiting the generality of the foregoing, the Company will
not hereafter enter into any agreement with respect to its securities that
grants, or modifies any existing agreement with respect to its securities to
grant, to the holder of its securities in connection with an incidental
registration of such securities higher priority to the rights granted to the
Purchaser under Section 2.2(b).

                 11. Remedies. Each holder of Registrable Securities, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement. The Company agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of the
provisions of this Agreement and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.

                 12. Certain Distributions. The Company shall not at any time
make a distribution on or with respect to the Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the resulting or surviving corporation and such Registrable
Securities are not changed or exchanged) of securities of another issuer if
holders of Registrable Securities are entitled to receive such securities in
such distribution as holders of Registrable Securities and any of the securities
so distributed are registered under the Securities Act, unless the securities to
be distributed to the holders of Registrable Securities are also registered
under the Securities Act.

                 13. Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions contained herein shall not be in any way
impaired thereby, it being intended that all of the rights and privileges of the
Purchasers shall be enforceable to the fullest extent permitted by law.

                           CERTIFICATE OF DESIGNATION
                         OF CONVERTIBLE PREFERRED STOCK,
                       SERIES A SETTING FORTH THE POWERS,
                      PREFERENCES, RIGHTS, QUALIFICATIONS,
                         LIMITATIONS AND RESTRICTIONS OF
                              SUCH PREFERRED STOCK

               Pursuant to Section 151 of the Delaware General Corporation Law,
VAALCO ENERGY, INC., a Delaware corporation (the "Corporation"), DOES HEREBY
CERTIFY:

               That pursuant to the authority conferred upon the Board of
Directors of the Corporation by the Certificate of Incorporation of the
Corporation (the "Charter"), the Board of Directors of the Corporation on
February 9, 1998 duly adopted the following resolution creating a series of
Preferred Stock designated as Convertible Preferred Stock, Series A and such
resolution has not been modified and is in full force and effect on the date
hereof:

               RESOLVED that, pursuant to the authority vested in the Board of
Directors of the Corporation in accordance with the provisions of the Charter, a
series of authorized Preferred Stock, par value $25.00 per share, of the
Corporation are hereby created and that the designation and number of shares
thereof and the voting powers, preferences and relative, participating, optional
and other special rights of the shares of such series of Preferred Stock, and
the qualifications, limitations and restrictions thereof are as follows:

Section 1.     DESIGNATION AND NUMBER.

               (a) The shares of such series of Preferred Stock shall be
designated as "Convertible Preferred Stock, Series A" ("Preferred Stock"). The
number of shares initially constituting the Preferred Stock shall be 10,000,
which number may be decreased (but not increased) by the Board of Directors
without a vote of stockholders; PROVIDED, HOWEVER, that such number may not be
decreased below the number of then outstanding shares of such series of
Preferred Stock.

               (b) The Preferred Stock shall, with respect to rights on
liquidation, dissolution or winding up, rank prior to all other classes and
series of Junior Stock of the Corporation now or hereafter authorized including,
without limitation, the Common Stock.

               (c) Capitalized terms used herein and not otherwise defined shall
have the meanings set forth in Section 9 below.

Section 2. DIVIDENDS AND DISTRIBUTIONS. In the event that the Corporation shall
declare a cash dividend or make any other distribution (including, without
limitation, in capital stock (which shall include, without limitation, any
options, warrants or other rights to acquire capital stock) of the Corporation,
whether or not pursuant to a shareholder rights plan, "poison pill" or similar
arrangement, or other property or assets) to holders of Common Stock, then the
Board of Directors shall declare, and the holder of each share of Preferred
Stock shall be entitled to receive, a dividend or distribution in an amount
equal 

                                       1
<PAGE>

to the amount of such dividend or distribution received by a holder of the
number of shares of Common Stock for which such share of Preferred Stock is
convertible on the record date for such dividend or distribution. Any such
amount shall be paid to the holders of shares of Preferred Stock at the same
time such dividend or distribution is made to holders of Common Stock.

               The holders of shares of Preferred Stock shall not be entitled to
receive any dividends or other distributions except as provided herein.

Section 3.     VOTING RIGHTS.

               In addition to any voting rights provided by law, the holders of
shares of Preferred Stock shall have the following voting rights:

               (a) Except as otherwise required by applicable law and so long as
the Preferred Stock is outstanding, each share of Preferred Stock shall entitle
the holder thereof to vote, in person or by proxy or written consent, at a
special or annual meeting of stockholders or in connection with any stockholder
action taken in lieu of a meeting of stockholders, on all matters voted on by
holders of Common Stock, including the election of directors, voting together as
a single class with all other shares entitled to vote thereon. With respect to
any such vote, each share of Preferred Stock shall entitle the holder thereof to
cast that number of votes per share as is equal to the number of votes that such
holder would be entitled to cast had such holder converted his shares of
Preferred Stock into Common Stock on the record date for determining the
stockholders of the Corporation eligible to vote on any such matters.

               (b) Unless the consent or approval of a greater number of shares
shall then be required by law, the affirmative vote of the holders of at least
66-2/3% of the outstanding shares of Preferred Stock, voting separately as a
single class, in person or by proxy, at a special or annual meeting of
stockholders called for the purpose, shall be necessary to (i) authorize, adopt
or approve an amendment to the Charter that would increase or decrease the par
value of the shares of Preferred Stock, or alter or change the powers,
preferences or special rights of the shares of Preferred Stock, (ii) amend,
alter or repeal the Charter so as to affect the shares of Preferred Stock
adversely, including, without limitation, by granting any voting right to any
holder of notes, bonds, debentures or other debt obligations of the Corporation,
or (iii) authorize, increase the authorized number of shares of, or issue
(including on conversion or exchange of any convertible or exchangeable
securities or by reclassification) any additional shares of Preferred Stock.

               (c) The holders of shares of Preferred Stock shall have, in
addition to the other voting rights set forth herein, the exclusive right,
voting separately as a single class, to elect three directors of the
Corporation, by written consent as provided herein, or at a special meeting of
such holders called as provided herein, one of which director shall be elected
to each of the corporation's three classes if the Corporation has a classified
Board of Directors. Such directors shall continue as directors (subject to
reelection or removal as provided in Section 3(d)(ii)) and the holders of
Preferred Stock shall have such class voting rights until such time as the
number of outstanding shares of Preferred Stock represent (after giving effect
to any adjustments) on a fully-diluted basis less than 5% of the total number of
shares of Common Stock outstanding, at which time such additional director shall
cease to be a director and such additional voting rights of the holders of
Preferred Stock shall terminate subject to revesting in the event of each and
every subsequent event of the character indicated above.

                                       2
<PAGE>
               (d) (i) The foregoing right of holders of shares of Preferred
Stock to take any action as provided in Section 3(c) may be exercised at any
annual meeting of stockholders or at a special meeting of holders of shares of
Preferred Stock held for such purpose as hereinafter provided or at any
adjournment thereof, or by the written consent, delivered to the Secretary of
the Corporation, of the holders of the minimum number of shares required to take
such action.

               So long as such right to vote continues (and unless such right
has been exercised by written consent of the minimum number of shares required
to take such action), the Chief Executive Officer or President of the
Corporation may call, and upon the written request of holders of record of at
least 5% of the outstanding shares of Preferred Stock, addressed to the
Secretary of the Corporation at the principal office of the Corporation, shall
call, a special meeting of the holders of shares entitled to vote as provided
herein. Such meeting shall be held within 30 days after delivery of such request
to the Secretary, at the place and upon the notice provided by law and in the
by-laws of the Corporation for the holding of meetings of stockholders.

                      (ii) At each meeting of stockholders at which the holders
of shares of Preferred Stock shall have the right, voting separately as a single
class, to elect three directors of the Corporation as provided in Section 3(c)
or to take any action, the presence in person or by proxy of the holders of
record of one-third of the total number of shares of Preferred Stock then
outstanding and entitled to vote on the matter shall be necessary and sufficient
to constitute a quorum. At any such meeting or at any adjournment thereof:

                      (A) the absence of a quorum of the holders of shares of
               Preferred Stock shall not prevent the election of directors other
               than those to be elected by the holders of shares of Preferred
               Stock, and the absence of a quorum of the holders of shares of
               any other class or series of capital stock shall not prevent the
               election of directors to be elected by the holders of shares of
               Preferred Stock, or the taking of any action as provided in this
               Section 3: and

                      (B) in the absence of a quorum of the holders of shares of
               Preferred Stock, a majority of the holders of such shares present
               in person or by proxy shall have the power to adjourn the meeting
               as to the actions to be taken by the holders of shares of
               Preferred Stock from time to time and place to place without
               notice other than announcement at the meeting until a quorum
               shall be present.

               For taking of any action as provided in Section 3(b) or Section
3(c) by the holders of shares of Preferred Stock, each such holder shall have
one vote for each share of such stock standing in his or her name on the
transfer books of the Corporation as of any record date fixed for such purpose
or, if no such date be fixed, at the close of business on the Business Day next
preceding the day on which notice is given, or if notice is waived, at the close
of business on the Business Day next preceding the day on which the meeting is
held; provided, however, that shares of Preferred Stock held by the Corporation
or any Affiliate of the Corporation shall not be deemed to be outstanding for
purposes of taking any action as provided in this Section 3.

               Each director elected by the holders of shares of Preferred Stock
as provided in Section 3(c) shall, unless his or her term shall expire earlier
in accordance with the 

                                       3
<PAGE>

provisions thereof, hold office until the annual meeting of stockholders at
which directors of the class stand for election or until his or her successor,
if any, is elected and qualified.

               If any director so elected by the holders of Preferred Stock
shall cease to serve as a director before his or her term shall expire (except
by reason of the termination of the voting rights accorded to the holders of
Preferred Stock in accordance with Section 3(c)), the holders of the Preferred
Stock then outstanding and entitled to vote for such director may, by written
consent as provided herein, or at a special meeting of such holders called as
provided herein, elect a successor to hold office for the unexpired term of the
director whose place shall be vacant.

               Any director elected by the holders of shares of Preferred Stock
voting separately as a single class may be removed from office with or without
cause by the vote or written consent of the holders of at least a majority of
the outstanding shares of Preferred Stock, at the time of removal. A special
meeting of the holders of shares of Preferred Stock may be called in accordance
with the procedures set forth in Section 3(d)(i).

Section 4. REDEMPTION. The Corporation shall not have any right to redeem any
shares of Preferred Stock.

Section 5.     REACQUIRED SHARES.

               Any shares of Preferred Stock converted, exchanged, redeemed,
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after the acquisition thereof. All such
shares of Preferred Stock shall upon their cancellation become authorized but
unissued shares of preferred stock, par value $25.00 per share, of the
Corporation and, upon the filing of an appropriate Certificate of Designation
with the Secretary of State of the State of Delaware, may be reissued as part of
another series of preferred stock, par value $25.00 per share, of the
Corporation subject to the conditions or restrictions on issuance set forth
herein, but in any event may not be reissued as shares of Preferred Stock or
other Parity Stock unless all of the shares of Preferred Stock issued on the
Issue Date shall have already been redeemed, converted or exchanged.

Section 6.     LIQUIDATION, DISSOLUTION OR WINDING UP.

               (a) If the Corporation shall commence a voluntary case under the
United States bankruptcy laws or any applicable bankruptcy, insolvency or
similar law of any other country, or consent to the entry of an order for relief
in an involuntary case under any such law or to the appointment of a receiver,
liquidator, assignee, custodian, trustee, sequestrator (or other similar
official) of the Corporation or of any substantial part of its property, or make
an assignment for the benefit of its creditors, or admit in writing its
inability to pay its debts generally as they become due (any such event, a
"Voluntary Liquidation Event"), or if a decree or order for relief in respect of
the Corporation shall be entered by a court having jurisdiction in the premises
in an involuntary case under the United States bankruptcy laws or any applicable
bankruptcy, insolvency or similar law of any other country, or appointing a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or other
similar official) of the Corporation or of any substantial part of its property,
or ordering the winding up or liquidation of its affairs, and on account of any
such event the Corporation shall liquidate, dissolve or wind up, or if the
Corporation shall otherwise liquidate, dissolve or wind up, no distribution
shall be made (i) to the holders of 

                                       4
<PAGE>

shares of Junior Stock unless, prior thereto, the holders of shares of Preferred
Stock shall have received the Liquidation Preference.

               (b) Neither the consolidation or merger of the Corporation with
or into any other Person nor the sale or other distribution to another Person of
all or substantially all the assets, property or business of the Corporation
shall be deemed to be a liquidation, dissolution or winding up of the
Corporation for purposes of this Section 6.

Section 7.     CONVERSION.

               (a) Any holder of Preferred Stock shall have the right, at its
option, at any time and from time to time, to convert, subject to the terms and
provisions of this Section 7, any or all of such holder's shares of Preferred
Stock into such number of fully paid and non-assessable shares of Common Stock
as is equal, subject to Section 7(g), to the product of the number of shares of
Preferred Stock being so converted multiplied by the quotient of (i) the
Purchase Price divided by (ii) the Conversion Price (as defined below) then in
effect. The Conversion Price shall be $1.00, subject to adjustment as set forth
in Section 7(d). Such conversion right shall be exercised by the surrender of
the shares to be converted to the Corporation at any time during usual business
hours at its principal place of business to be maintained by it, accompanied by
written notice that the holder elects to convert such shares and specifying the
name or names (with address) in which a certificate or certificates for shares
of Common Stock are to be issued and (if so required by the Corporation) by a
written instrument or instruments of transfer in form reasonably satisfactory to
the Corporation duly executed by the holder or its duly authorized legal
representative and transfer tax stamps or funds therefor, if required pursuant
to Section 7(j). All shares of Preferred Stock surrendered for conversion shall
be delivered to the Corporation for cancellation and cancelled by it and no
shares of Preferred Stock shall be issued in lieu thereof.

               (b) As promptly as practicable after the surrender, as herein
provided, of any shares of Preferred Stock for conversion pursuant to Section
7(a), the Corporation shall deliver to or upon the written order of the holder
of such shares so surrendered a certificate or certificates representing the
number of fully paid and non-assessable shares of Common Stock into which such
shares of Preferred Stock may be or have been converted in accordance with the
provisions of this Section 7. Subject to the following provisions of this
paragraph and of Section 7(d), such conversion shall be deemed to have been made
immediately prior to the close of business on the date that such shares of
Preferred Stock shall have been surrendered in satisfactory form for conversion,
and the Person or Persons entitled to receive the Common Stock deliverable upon
conversion of such shares of Preferred Stock shall be treated for all purposes
as having become the record holder or holders of such Common Stock at such
appropriate time, and such conversion shall be at the Conversion Price in effect
at such time; PROVIDED, HOWEVER, that no surrender shall be effective to
constitute the Person or Persons entitled to receive the Common Stock
deliverable upon such conversion as the record holder or holders of such Common
Stock while the share transfer books of the Corporation shall be closed (but not
for any period in excess of five days), but such surrender shall be effective to
constitute the Person or Persons entitled to receive such Common Stock as the
record holder or holders thereof for all purposes immediately prior to the close
of business on the next succeeding day on which such share transfer books are
open, and such conversion shall be deemed to have been made at, and shall be
made at the Conversion Price in effect at, such time on such next succeeding
day.

                                       5

               (c) To the extent permitted by law, when shares of Preferred
Stock are converted, all dividends declared and unpaid on the Preferred Stock so
converted to the date of conversion shall be immediately due and payable and
must accompany the shares of Common Stock issued upon such conversion.

               (d) The Conversion Price shall be subject to adjustment as
follows:

               (i) In case the Corporation shall at any time or from time to
        time (A) pay a dividend or make a distribution (other than a dividend or
        distribution paid or made to holders of shares of Preferred Stock in the
        manner provided in Section 2) on the outstanding shares of Common Stock
        in capital stock (which, for purposes of this Section 7(d) shall
        include, without limitation, any dividends or distributions in the form
        of options, warrants or other rights to acquire capital stock) of the
        Corporation, (B) subdivide the outstanding shares of Common Stock into a
        larger number of shares, (C) combine the outstanding shares of Common
        Stock into a smaller number of shares, or (D) issue any shares of its
        capital stock in a reclassification of the Common Stock then, and in
        each such case, the Conversion Price in effect immediately prior to such
        event shall be adjusted (and any other appropriate actions shall be
        taken by the Corporation) so that the holder of any share of Preferred
        Stock thereafter surrendered for conversion shall be entitled to receive
        the number of shares of Common Stock or other securities of the
        Corporation that such holder would have owned or would have been
        entitled to receive upon or by reason of any of the events described
        above, had such share of Preferred Stock been converted immediately
        prior to the occurrence of such event. An adjustment made pursuant to
        this Section 7(d)(i) shall become effective retroactively (A) in the
        case of any such dividend or distribution, to a date immediately
        following the close of business on the record date for the determination
        of holders of Common Stock entitled to receive such dividend or
        distribution or (B) in the case of any such subdivision, combination or
        reclassification, to the close of business on the day upon which such
        corporate action becomes effective.

               (ii) In case the Corporation shall at any time or from time to
        time issue shares of Common Stock (or securities convertible into or
        exchangeable for Common Stock, or any options, warrants or other rights
        to acquire shares of Common Stock) for a consideration per share less
        than the Current Market Price per share of Common Stock then in effect
        at the record date or issuance date, as the case may be (the "Date"),
        referred to in the following sentence (treating the price per share of
        any security convertible or exchangeable or exercisable into Common
        Stock as equal to (A) the sum of the price for such security
        convertible, exchangeable or exercisable into Common Stock plus any
        additional consideration payable (without regard to any anti-dilution
        adjustments) upon the conversion, exchange or exercise of such security
        into Common Stock divided by (B) the number of shares of Common Stock
        initially underlying such convertible, exchangeable or exercisable
        security), then, and in each such case, the Conversion Price then in
        effect shall be adjusted by dividing the Conversion Price in effect on
        the day immediately prior to the Date by a fraction (x) the numerator of
        which shall be the sum of the number of shares of Common Stock
        outstanding on the Date plus the number of additional shares of Common
        Stock issued or to 

                                       6
<PAGE>

        be issued (or the maximum number into which such convertible or 
        exchangeable securities initially may convert or exchange or for which
        such options, warrants or other rights initially may be exercised) and
        (y) the denominator of which shall be the sum of the number of shares of
        Common Stock outstanding on the Date plus the number of shares of Common
        Stock which the aggregate consideration for the total number of such
        additional shares of Common Stock so issued or would be issued upon the
        conversion, exchange or exercise of such convertible or exchangeable
        securities or options, warrants or other rights (plus the aggregate
        amount of any additional consideration initially payable upon such
        conversion, exchange or exercise of such security) would purchase at the
        Current Market Price per share of Common Stock on the Date. Such
        adjustment shall be made whenever such shares, securities, options,
        warrants or other rights are issued, and shall become effective
        retroactively to a date immediately following the close of business (i)
        in the case of issuance to stockholders of the Corporation, as such, on
        the record date for the determination of stockholders entitled to
        receive such shares, securities, options, warrants or other rights and
        (ii) in all other cases, on the date ("issuance date") of such issuance;
        PROVIDED that: (A) the determination as to whether an adjustment is
        required to be made pursuant to this Section 7(d)(ii) shall be made upon
        the issuance of such shares or such convertible or exchangeable
        securities, options, warrants or other rights; (B) if any convertible or
        exchangeable securities, options, warrants or other rights (or any
        portions thereof) which shall have given rise to an adjustment pursuant
        to this Section 7(d)(ii) shall have expired or terminated without the
        exercise thereof and/or if by reason of the terms of such convertible or
        exchangeable securities, options, warrants or other rights there shall
        have been an increase or increases, with the passage of time or
        otherwise, in the price payable upon the exercise or conversion thereof,
        then the Conversion Price hereunder shall be readjusted (but to no
        greater extent than originally adjusted) on the basis of (x) eliminating
        from the computation any additional shares of Common Stock corresponding
        to such convertible or exchangeable securities, options, warrants or
        other rights as shall have expired or terminated, (y) treating the
        additional shares of Common Stock, if any, actually issued or issuable
        pursuant to the previous exercise of such convertible or exchangeable
        securities, options, warrants or other rights as having been issued for
        the consideration actually received and receivable therefor and (z)
        treating any of such convertible or exchangeable securities, options,
        warrants or other rights which remain outstanding as being subject to
        exercise or conversion on the basis of such exercise or conversion price
        as shall be in effect at this time; and (C) no adjustment in the
        Conversion Price shall be made pursuant to this Section 7(d)(ii) as a
        result of any issuance of securities by the Corporation in respect of
        which an adjustment to the Conversion Price is made pursuant to Section
        7(d)(i).

               (iii) In the case the Corporation, at any time or from time to
        time, shall take any action affecting its Common Stock similar to or
        having an effect similar to any of the actions described in any of
        Section 7(d)(i) and Section 7(d)(ii), or Section 7(h) (but not including
        any action described in any such Section) and the Board of Directors of
        the Corporation in good faith determines that it would be equitable in
        the circumstances to adjust the Conversion Price as a result of such
        action, then, and in each such case, the 

                                       7
<PAGE>
        Conversion Price shall be adjusted in such manner and at such time as
        the Board of Directors of the Corporation in good faith determines would
        be equitable in the circumstances (such determination to be evidenced in
        a resolution, a certified copy of which shall be mailed to the holders
        of the Preferred Stock).

               (iv) Notwithstanding anything herein to the contrary, no
        adjustment under this Section 7(d) need be made to the Conversion Price
        unless such adjustment would require an increase or decrease of at least
        1% of the Conversion Price then in effect. Any lesser adjustment shall
        be carried forward and shall be made at the time of and together with
        the next subsequent adjustment, which, together with any adjustment or
        adjustments so carried forward, shall amount to an increase or decrease
        of at least 1% of such Conversion Price. Any adjustment to the
        Conversion Price carried forward and not theretofore made shall be made
        immediately prior to the conversion of any shares of Preferred Stock
        pursuant hereto.

               (v) Notwithstanding anything herein to the contrary, no
        adjustment under this Section 7(d) shall be made upon the grant of
        options to employees or directors of the Corporation pursuant to benefit
        plans approved by the Board of Directors of the Corporation or upon the
        issuance of shares of Common Stock upon exercise of such options if the
        exercise price thereof was not less than the Market Price of the Common
        Stock on the date such options were granted.

               (e) If the Corporation shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, and shall thereafter and before the distribution to stockholders
thereof legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment in the Conversion Price then in
effect shall be required by reason of the taking of such record.

               (f) Upon any increase or decrease in the Conversion Price, then,
and in each such case, the Corporation promptly shall deliver to each registered
holder of Preferred Stock at least 10 Business Days prior to effecting any of
the foregoing transactions a certificate, signed by the President or a
Vice-President and by the Treasurer or an Assistant Treasurer or the Secretary
or an Assistant Secretary of the Corporation, setting forth in reasonable detail
the event requiring the adjustment and the method by which such adjustment was
calculated and specifying the increased or decreased Conversion Price then in
effect following such adjustment.

               (g) No fractional shares or scrip representing fractional shares
shall be issued upon the conversion of any shares of Preferred Stock. If more
than one share of Preferred Stock shall be surrendered for conversion at one
time by the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate Purchase
Price of the shares of Preferred Stock so surrendered. If the conversion of any
share or shares of Preferred Stock results in a fraction, an amount equal to
such fraction multiplied by the Current Market Price of the Common Stock on the
Business Day preceding the day of conversion shall be paid to such holder in
cash by the Corporation.

               (h) In case of any capital reorganization or reclassification or
other change of outstanding shares of Common Stock (other than a change in par
value, or from par value to no par value, or from 

                                       8
<PAGE>
no par value to par value), or in case of any consolidation or merger of the
Corporation with or into another Person (other than a consolidation or merger in
which the Corporation is the resulting or surviving Person and which does not
result in any reclassification or change of outstanding Common Stock), or in
case of any sale or other disposition to another Person of all or substantially
all of the assets of the Corporation (any of the foregoing, a "Transaction"),
the Corporation, or such successor or purchasing Person, as the case may be,
shall execute and deliver to each holder of Preferred Stock at least 10 Business
Days prior to effecting any of the foregoing Transactions a certificate that the
holder of each share of Preferred Stock then outstanding shall have the right
thereafter to convert such share of Preferred Stock into the kind and amount of
shares of stock or other securities (of the Corporation or another issuer) or
property or cash receivable upon such Transaction by a holder of the number of
shares of Common Stock into which such share of Preferred Stock could have been
converted immediately prior to such Transaction. Such certificate shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 7. If, in the case of any such
Transaction, the stock, other securities, cash or property receivable thereupon
by a holder of Common Stock includes shares of stock or other securities of a
Person other than the successor or purchasing Person and other than the
Corporation, which controls or is controlled by the successor or purchasing
Person or which, in connection with such Transaction, issues stock, securities,
other property or cash to holders of Common Stock, then such certificate also
shall be executed by such Person, and such Person shall, in such certificate,
specifically acknowledge the obligations of such successor or purchasing Person
and acknowledge its obligations to issue such stock, securities, other property
or cash to the holders of Preferred Stock upon conversion of the shares of
Preferred Stock as provided above. The provisions of this Section 7(h) and any
equivalent thereof in any such certificate similarly shall apply to successive
Transactions.

               (i) The Corporation shall at all times reserve and keep available
for issuance upon the conversion of the Preferred Stock, such number of its
authorized but unissued shares of Common Stock as will from time to time be
sufficient to permit the conversion of all outstanding shares of Preferred
Stock, and shall take all action required to increase the authorized number of
shares of Common Stock if at any time there shall be insufficient authorized but
unissued shares of Common Stock to permit such reservation or to permit the
conversion of all outstanding shares of Preferred Stock.

               (j) The issuance or delivery of certificates for Common Stock
upon the conversion of shares of Preferred Stock shall be made without charge to
the converting holder of shares of Preferred Stock for such certificates or for
any tax in respect of the issuance or delivery of such certificates or the
securities represented thereby, and such certificates shall be issued or
delivered in the respective names of, or (subject to compliance with the
applicable provisions of federal and state securities laws) in such names as may
be directed by, the holders of the shares of Preferred Stock converted;
PROVIDED, HOWEVER, that the Corporation shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issuance and
delivery of any such certificate in a name other than that of the holder of the
shares of Preferred Stock converted, and the Corporation shall not be required
to issue or deliver such certificate unless or until the Person or Persons
requesting the issuance or delivery thereof shall have paid to the Corporation
the amount of such tax or shall have established to the reasonable satisfaction
of the Corporation that such tax has been paid.

Gentlemen:

         Reference is made to (i) the Stock Acquisition Agreement and Plan of
Reorganization, dated as of February 17, 1998 and amended as of April 21, 1998
(the "Stock Acquisition Agreement"), among Vaalco Energy, Inc., a Delaware
corporation ("Vaalco"), The 1818 Fund II, L.P., a Delaware limited partnership
(the "Fund"), and 1818 Oil Corp., a Delaware corporation ("1818 Oil"), and (ii)
the Private Placement Memorandum dated April 15, 1998 of Vaalco (the "PPM").

         Vaalco hereby agrees that it shall, as soon as practicable after the
date hereof, take all action necessary to amend the Certificate of Incorporation
of Vaalco (including, without limitation, causing a special meeting of the
stockholders of Vaalco to be called or circulating a written consent and mailing
an information statement to stockholders in connection with any stockholder
action taken by written consent) so that Vaalco will have reserved and available
for issuance such number of authorized but unissued shares of Common Stock, par
value $.10 per share (the "Common Stock"), of Vaalco as would be sufficient to
permit the conversion of all outstanding (i) shares of Preferred Stock, par
value $25.00 per share (the "Preferred Stock"), of Vaalco and (ii) options,
warrants or similar rights with respect to shares of Common Stock (collectively,
the "Options"), and each of the undersigned agrees to vote all of their shares
of Common Stock and Preferred Stock in favor of such amendment.

         Notwithstanding anything to the contrary contained in the Certificate
of Designation of the Preferred Stock or in any plan or agreement pursuant to
which any Options were issued (collectively, the "Option Agreements'), each of
the undersigned

<PAGE>

                                                                               2

hereby understands and agrees that, upon the consummation of the transactions
contemplated by the Stock Acquisition Agreement and the PPM, Vaalco will not
have reserved and available for issuance such number of authorized but unissued
shares of Common Stock as would be sufficient to permit the conversion of all
outstanding Options and shares of Preferred Stock and each of the undersigned
hereby waives any breach by Vaalco of the terms of the Preferred Stock or any
Option Agreement in connection therewith.

         In furtherance of the foregoing, each person listed below agrees not to
convert the number of Options or shares of Preferred Stock set forth opposite
their name until such time as Vaalco has reserved and available for issuance
such number of authorized but unissued shares of Common Stock as would be
sufficient to permit the conversion of all outstanding Options and shares of
Preferred Stock:

                                  Shares of
                               Preferred Stock                 Options
