                               COMMON STOCK OPTION

                         AMERICAN ENERGY SERVICES, INC.
                              (a Texas Corporation)

         FOR VALUE RECEIVED, AMERICAN ENERGY SERVICES, INC. (the "Company")
hereby grants to David Marks (the "Holder"), subject to the terms and conditions
hereinafter set forth, the option to purchase an aggregate of TWO HUNDRED
THOUSAND (200,000) shares of common stock, par value $.001 (the "Common Stock")
of the Company at an exercise price of $0.50 per share, subject to adjustment as
provided in Section 5 below.

     1. This Option may be exercised by the holder hereof, in whole or in part
(but not as to a fractional share), by the presentation and surrender of this
Option with the form of Election to Purchase duly executed, at the principal
office of the Company (or at such other address as the Company may designate by
notice in writing to the holder hereof at the address of such holder appearing
on the books of the Company), together with payment of the exercise price by
cash, certified check, cashier's check or wire transfer. The Company shall
deliver to the holder, as promptly as practicable, certificates representing the
shares being purchased; and, in case of exercise hereof in part only, the
Company upon surrender hereof, will deliver to the holder a new Option
Certificate or Option Certificates of like tenor entitling the holder to
purchase the number of shares as to which this Option has not been exercised.

     2. Nothing contained herein shall be construed to confer upon the holder of
this Option, as such, any of the rights of a shareholder of the Company.

     3. The Company shall not issue certificates representing fractions of
shares of Common Stock upon the exercise of this Option, but shall make a cash
payment for any fractional share based on the market price of the Common Stock
on the date of exercise, which shall be the closing sale price on the principal
exchange on which the Common Stock is traded; or if not traded on any exchange,
then the representative closing bid price in the over-the-counter market. All
calculations under this Section 3 and under Section 5 shall be made to the
nearest cent or shares, as the case may be.

     4. This Option is exchangeable, upon its surrender by the holder at the
office of the Company referred to in Section 1 above, for new Options
(containing the same terms as this Option) each representing the right to
purchase such number of shares of Common Stock as shall be designated by such
holder at the time of such surrender (but not exceeding in the aggregate the
remaining number of shares of Common Stock which may be purchased hereunder).
Upon receipt of evidence satisfactory to the Company of the loss, theft,
destruction or mutilation of this Option and upon delivery of a bond of
indemnity satisfactory to the Company (or, in the case of mutilation, upon

<PAGE>

surrender of this Option), the Company will issue to the holder a replacement
Option (containing the same terms as this Option). As used herein, "Option"
shall include all new Options issued in exchange for or replacement of this
Option.

     5. If the Company shall pay a dividend in shares of its Common Shares,
subdivide (split) its outstanding shares of Common Stock, combine (reverse
split) its outstanding shares of Common Stock, issue by reclassification of its
shares of Common Stock any shares or other securities of the Company, or
distribute to holders of its Common Stock any securities of the Company or of
another entity, the number of shares of Common Stock or other securities the
holder hereof is entitled to purchase pursuant to this Option immediately prior
thereto shall be adjusted so that the holder shall be entitled to receive upon
exercise the number of shares of Common Stock or other securities which he or
she would have owned or would have been entitled to receive after the happening
of any of the events described above had this Option been exercised immediately
prior to the happening of such event, and the exercise price per share shall be
correspondingly adjusted; provided, however, that no adjustment in the number of
shares and/or the exercise price shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such number
and/or price; and provided further, however, that any adjustments which by
reason of this Section 5 are not required to be made shall be carried forward
and taken into account in any subsequent adjustment. An adjustment made pursuant
to this Section 5 shall become effective immediately after the record date in
the case of the stock dividend or other distribution and shall become effective
immediately after the effective date in the case of a subdivision, combination
or reclassification. The holder of this Option shall be entitled to participate
in any subscription or other rights offering made to holders of the Company's
Common Stock to the extent he or she would have been entitled had this Option
been exercised in the full number of shares as to which this Option remains
unexercised immediately prior to the record date for such rights offering. If
the Company is consolidated or merged with or into another corporation or if all
or substantially all of its assets are conveyed to another corporation this
Option shall thereafter be exercisable for the purchase of the kind and number
of shares of stock or other securities or property, if any, receivable upon such
consolidation, merger or conveyance by a holder of the number of shares of
Common Stock of the Company which could have been purchased on the exercise of
this Option immediately prior to such consolidation, merger or conveyance; and,
in any such case, appropriate adjustment (as determined by the Board of
Directors) shall be made in the application of the provisions herein set forth
with respect to the rights and interests thereafter of the holder of this Option
to the end that the provisions set forth herein (including provisions with
respect to changes in and other adjustments of the number of shares of Common
Stock the holder of this Option is entitled to purchase) shall thereafter by
applicable, as nearly as possible, in relation to any shares of Common Stock or
other securities or other property thereafter deliverable upon the exercise of
this Option. Upon any adjustment of the number of shares of Common Stock or
other securities the holder of this Option is entitled to purchase, and of any
change in exercise price per share, then in each such case the Company shall
give written notice thereof to the then registered holder of this Option at the
address of such holder as shown on the books of the Company, which notice shall
state such change and set forth in reasonable detail the method of calculation
and the facts upon which such calculation is based. Each such notice shall be
accompanied by a statement of the firm of independent certified public
accountants retained to audit the financial statements of the Company to the
effect that such firm concurs in the Company's calculation of the change.

     6. If at any time:

     (a) The Company shall declare a dividend or other distribution on its
Common Stock payable otherwise than in cash at the same rate as the immediately
preceding regular dividend or in Common Stock; or

     (b) The Company shall authorize the granting to the holders of its Common
Stock of rights to subscribe for or purchase any shares of capital stock of any
class or of any other rights; or

     (c) There shall be any plan or agreement of reorganization, or
reclassification of the capital stock of the Company, or consolidation or merger
of the Company with, or sale of all or substantially all of its assets to,
another corporation; or

     (d) There shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Company;

then the Company shall give to the registered holder of this Option at the
address of such holder as shown on the books of the Company, at least ten (10)
days prior to the applicable record date or dates, a written notice summarizing
such action or event and stating the record date or dates for any such dividend
or rights (or if a record is not to be taken, the date or dates as of which the
holders of Common Stock of record to be entitled to such dividend or rights are
to be determined), the date on which any such reorganization, reclassification,
consolidation, merger, sale of assets, dissolution, liquidation or winding up is
expected to become effective, and the date or dates as of which it is expected
the holders of Common Stock of record shall be entitled to effect any exchange
of their shares of Common Stock for securities of other property deliverable
upon any such reorganization, reclassification, consolidation, merger, sale of
assets, dissolution, liquidation or winding up.

     In Witness Whereof, the Company has caused this Option to be signed by its
duly authorized officers on the ______ day of May, 2000.

4.  Administration.

     (a) The Plan shall be administered by the Committee. The Board shall
annually appoint the members of the Committee at the annual organizing meeting
of the Board. Each member of the Committee shall be a Disinterested Person.

     (b) The Board shall fill all vacancies on the Committee and may remove any
member of the Committee at any time with or without cause. The Committee shall
select its own chairman and shall adopt, alter or repeal such rules and
procedures as it may deem proper and shall hold its meetings at such times and
places as it may determine. The Committee shall keep minutes of its meetings.
Action by a majority of the Committee members present at any meeting at which a
quorum is present, or action approved in writing by all members of the Committee
without a meeting, shall constitute the acts of the Committee.

     (c) Subject to the provisions of the Plan, the Committee shall have the
full and final authority to (i) determine the eligible employees of the Company
and its Subsidiaries to whom, and the times at which, options shall be granted
and the number of shares subject to each option; (ii) prescribe, amend and
rescind rules and regulations relating to the Plan; (iii) determine the
provisions of options granted under the Plan (which need not be identical) and,
with the consent of the holder thereof, amend or modify any option; (iv)
interpret the Plan and the respective options; and (v) make all other
determinations necessary or advisable for administering the Plan. All
determinations and interpretations by the Committee shall be binding upon all
parties. No member of the Committee or the Board shall be liable for any action
or determination made in good faith in respect of the Plan or any option granted
under it.

Plan.

Company and its Subsidiaries. Any reference in the Plan to "employment by the
Company" shall also be deemed to include employment by any Subsidiary of the
Company. Determination by the Committee or the Board as to who are eligible
employees shall be conclusive.

     (b) A person who is a director of the Company shall not be considered an
officer or employee for the purpose of the Plan solely because he or she is a
director. However, a person who otherwise is an eligible officer or employee
shall not be disqualified by virtue of being a director of the Company or any
Subsidiary.

     (c) More than one option may be granted to any eligible employee.

                                        3

<PAGE>

6.  Option Price.

     The purchase price of the Common Stock under each option shall be
determined by the Committee. The purchase price shall be at least 100 percent
(100%) of the Fair Market Value of the Common Stock on the date of grant of
option. The purchase price under an option granted to an officer or employee who
is a Ten Percent Stockholder shall be at least 110% of the Fair Market Value of
the Common Stock on the date of the grant of the option.

7.  Annual Limitation on Grants to One Officer or Employee.

     No option shall be granted during any calendar year to any individual under
the Plan if the aggregate fair market value (as of the time the option is
granted) of the Common Stock with respect to which incentive stock options are
exercisable for the first time by such individual during any calendar year
(under the Plan and any other plan of the Company, its Parent, if any, and its
Subsidiaries) exceeds $200,000.

8.  Terms and Exercise of Option.

     (a) Maximum Ten-Year Termination Date. Each option shall expire no later
than ten years after the date on which it shall have been granted, but the
Committee in its discretion may prescribe a shorter period for any individual
option or options. Any option granted to a person who is a Ten Percent
Stockholder shall terminate no later than five years after the date on which the
option was granted. The date of termination pursuant to this paragraph is
referred to hereinafter as the "termination date of the option."

     (b) Vesting. Options shall be exercisable at such times and in such
installments, if any, as the Committee may determine. In the event any option is
exercisable in installments, any shares which may be purchased during any year
or other period which are not purchased during such year or other period may be
purchased at any time or from time to time during any subsequent year or period
during the term of the option unless otherwise provided in the Stock Option
Agreement.

     (c) Means of Exercise of Option. An option shall be exercised by written
notice to the Secretary or Treasurer of the Company at its then principal office
which is received not later than 5:00 p.m. of the expiration date. The notice
shall specify the number of shares as to which the option is being exercised and
shall be accompanied by payment in full of the purchase price for such shares.
An optionee at his discretion may, in lieu of cash payment, deliver Common Stock
already owned, with a Fair Market Value (on the date of exercise) equal to the
purchase price for the shares being acquired pursuant to the exercise of the
option, as payment for the exercise of any option. In the event an option is
being exercised in whole or in part, pursuant to Section 8 (f) or (g) hereof by
any person other than the optionee, a notice of election shall be accompanied by
proof satisfactory to the Company of the rights of such person to exercise said
option. An optionee shall not, by virtue of the granting of an option, be
entitled to any rights of a shareholder

                                        4

<PAGE>

in the Company and he or she shall not be considered a record holder of shares
purchased by him until the date on which he shall actually be recorded as the
holder of such shares upon the stock records of the Company. The Company shall
not be required to pay to the person exercising the option the cash equivalent
of any fractional share interest unless so determined by the Committee.

     (d) Options are Nontransferable. No option may be transferred by the
optionee (except in connection with death or disability as provided in Sections
8(f) and (g)).

     (e) Options Lapse Three Months after Termination of Employment. In the
event of the termination of an optionee's employment by the Company and its
Subsidiaries at any time for any reason (excluding disability or death), the
optionee's options and all rights thereunder shall expire three months after the
date of termination of employment. The option shall be exercisable by the
optionee at any time within three months, but only to the extent exercisable by
the optionee on the date of termination of his or her employment.

     (f) Option Exercisable Six Months After Termination in Event of Disability.
In the event the optionee is permanently and totally disabled (within the
meaning of Section 105(d)(4), or any successor section, of the Code), the
optionee's option and all rights thereunder shall expire six months after the
date of termination of employment. The option shall be exercisable by the
optionee (or the optionee's legal representative) at any time within such six
months.

     (g) Option Exercisable Six Months after Date of Death. If an optionee shall
die while in the employ of the Company or any of its Subsidiaries, his option
may be exercised by his designated beneficiaries (or if none have been
effectively designated, by his executor, administrator or the person to whom
rights under his option shall pass by way of his will or by the laws of descent
and distribution) at any time within six (6) months after date of his death, but
only to the extent exercisable by the optionee at his death. The option shall
expire six months after the date of the optionee's death.

     (h) No Right to Continued Employment. Nothing in the Plan or in any option
granted pursuant hereto shall confer on any individual any right to continue in
the employ of the Company or any of its Subsidiaries or prevent or interfere in
any way with the right of the Company or its Subsidiaries to terminate the
optionee's employment at any time, with or without cause.

     (i) Options Must be Evidenced by Writing. Each option granted pursuant to
the Plan shall be evidenced by a written Stock Option Agreement, duly executed
by the Company and the optionee, in such form and containing such provisions as
the Committee or Board may from time to time authorize or approve.

                                        5

9.  Adjustments.

     The Stock Option Agreement shall contain appropriate provisions for the
adjustment of the kind and number of shares subject to each outstanding option,
and for the adjustment of the exercise price per share, in the event of any
changes in the outstanding Common Stock of the Company by reason of stock
dividends, stock splits, recapitalization, reorganizations, mergers,
consolidations, combinations or exchanges of shares, and the like. In the event
of any such change or changes in the outstanding Common Stock, and as often as
the same shall occur, the kind and aggregate number of shares available under
the Plan shall be appropriately adjusted by the Committee or Board, whose
determination shall be binding and conclusive.

10.  Amendment and Termination.

     (a) Unless the Plan shall have been sooner terminated as provided herein,
it shall terminate on, and no option shall be granted thereunder after April 30,
2010. The Board may at any time prior to that date alter, suspend or terminate
the Plan as it may deem advisable, except that it may not without further
shareholder approval: (i) increase the maximum number of shares subject to the
Plan (except for changes pursuant to Section 9); (ii) extend the period during
which options may be granted or exercised; or (iii) make any other changes
unless the Board determines that the change would not materially increase the
cost of the Plan to the Company. Except as otherwise hereinafter provided, no
alteration, suspension or termination of the Plan may, without the consent of
the employee to whom any option shall have theretofore been granted (or the
person or persons entitled to exercise such option under Section 8(f) or (g) of
the Plan), terminate his option or adversely affect his rights thereunder.

     (b) Anything herein to the contrary notwithstanding, in the event that the
Board shall at any time declare it advisable to do so in connection with any
proposed sale or conveyance of all or substantially all of the assets of the
Company or of any proposed consolidation or merger of the Company, the Company
may give written notice to the holder of any option that his option may be
exercised only within thirty (30) days after the date of such notice but not
thereafter, and all rights under said option which shall have not been so
exercised shall terminate at the expiration of such thirty (30) days, provided
that the proposed sale, conveyance, consolidation or merger to which such notice
shall relate shall be consummated within six (6) months after the date of such
notice. In the event such notice shall have been given, any such option may be
exercised either in whole or in part notwithstanding the vested period required
under the terms of the option for the exercise thereof. If such proposed sale,
conveyance, consolidation or merger shall not be consummated within said time
period, no unexercised rights under any option shall be affected by such notice
except that such option may not be exercised between the date of expiration of
such thirty (30) days and the date of the expiration of such six (6) months.

                                        6

11.  Indemnification.

     Any member of the Committee or the Board who is made, or threatened to be
made, a party to any action or proceeding, whether civil or criminal, by reason
of the fact that the member is or was a member is or was a member of the
Committee or the Board insofar as it relates to the Plan shall be indemnified by
the Company, and the Company may advance his related expenses, to the full
extent permitted by law or to any greater extent as provided in the Company's
Certificate of Incorporation or By-Laws or in any agreement between the Company
and the member.

12.  Effective Date of the Plan.

     The Plan shall become effective on, and options may be granted thereunder
after May 1, 2000, provided, however, that if the Plan shall not be approved by
the holders of a majority of the outstanding voting stock of the Company within
12 months of said date, the Plan and all options granted thereunder shall be and
become null and void, and provided, further, that no options granted by the
Commission may be exercised prior to the approval of the Plan by shareholders.

13.  Expenses.

     The Company shall pay all fees and expenses incurred in connection with the
establishment and administration of the Plan.

14.  Government Regulations.  Registration and Listing of Stock.

     (a) The Plan, and the grant and exercise of options thereunder, and the
Company's obligation to sell and deliver stock under such options, shall be
subject to all applicable federal and state laws, rules and regulations and to
such approvals by any regulatory or governmental agency as may be required.

     (b) Unless a registration statement under the Securities Act of 1933 and
the applicable rules and regulations thereunder (collectively the "Act") is then
in effect with respect to shares issued upon exercise of any option (which
registration shall not be required), the Company shall require that the offer
and sale of such shares be exempt from the registration provisions of said act.
In furtherance of such exemption, the Company may require, as a condition
precedent to the exercise of any option, that the person exercising the option
give to the Company a written representation and undertaking, satisfactory in
the form and substance to the Company, that he or she is acquiring the shares
for his or her own account for investment and not with a view to the
distribution or resale thereof and otherwise establish to the Company's
satisfaction that the offer or sale of the shares issuable upon the exercise of
the option will not constitute or result in any breach or violation of the Act
or any similar state act or statute or any rules or regulations thereunder. In
the event a Registration Statement under the Act is not then in effect with
respect to the shares of Common Stock issued upon exercise of an option, the
Company shall place upon any stock certificate an appropriate legend referring
to the restrictions on disposition under the Act.

     (c) In the event the class of shares issuable upon the exercise of any
option is listed on

                                       7
<PAGE>

any national securities exchange, the Company shall not be required to issue or
deliver any certificate for shares upon the exercise of any options prior to the
listing of the shares so issuable on such national securities exchange and prior
to the registration of the same under the Exchange Act or any similar act or
statute.
