SULPHCO, INC.
STOCK OPTION AGREEMENT

This Stock Option Agreement (the "Agreement") is made and entered into as of May
23, 2006 (hereinafter referred to as the "Effective Date"), by and between
SULPHCO, INC., a Nevada corporation (the "Company"), and RUDOLF W. GUNNERMAN
("Optionee"), with reference to the following facts:

A.  The Company has duly adopted the 2006 Stock Option Plan (hereinafter
referred to as the "Plan"), subject to stockholder approval, which authorizes
the Option Committee (the "Committee") to grant stock options, and which Plan is
intended to encourage ownership of stock of the Company by officers, directors,
consultants, advisors and other key management employees and to provide
additional incentive for them to promote the success of the Company.

B. The Committee has determined that Optionee is entitled to participate in the
Plan, and has taken appropriate action to authorize the granting of a stock
option to Optionee for the number of shares, at the price per share and on the
terms set forth in this Agreement, subject to stockholder approval of the Plan.

C. Optionee desires to participate in the Plan and to receive an option on the
terms and conditions set forth in this Agreement.

NOW, THEREFORE, the parties agree as follows:

1. Grant of Option. The Company hereby grants to Optionee the right and option
(hereinafter referred to as the "Option") to purchase all or any part of an
aggregate of One Million (1,000,000) shares (the "Option Shares") of common
stock, $.001 par value, of the Company (the "Common Stock") at the times and on
the terms and conditions set forth in this Agreement. The Option shall be a
“non-statutory stock option” under the Internal Revenue Code of 1986.

2. Exercise Price. The purchase price (the "Exercise Price") of each Option
Share shall be $9.03 per share of the Company’s Common Stock.

3. Option Period. 

3.1 The Option shall be exercisable on and after the first to occur of a “Change
in Control” or a “Vesting Event” (as such quoted terms are defined in paragraph
3 this Agreement) and shall expire, and all rights to purchase the Option Shares
shall terminate, at the close of business on the day immediately preceding the
third anniversary of the Effective Date, unless terminated earlier as provided
in this Agreement. The Option shall not be exercisable until the time at which
all legal requirements in connection with the Plan have been fully complied
with, including stockholder approval of the Plan. If Optionee is subject to the
reporting requirements of Section 16(a) of the Securities Exchange Act of 1934
(the "Exchange Act"), the Option shall not be exercisable until at least six
months and one day from the Effective Date.

--------------------------------------------------------------------------------

 
3.2 For purposes of this Agreement, “Vesting Event” shall mean the reporting by
the Company of $50,000,000 or more of gross revenues in a fiscal year.    

3.3 (a)  A Change in Control shall be deemed to have occurred if (i) a Takeover
Transaction (as defined in paragraph (2) of this Section 3.10) occurs; or
(ii) any election of directors of the Company takes place (whether by the
directors then in office or by the stockholders at a meeting or by written
consent) and a majority of the directors in office following such election are
individuals who were not nominated by a vote of two-thirds of the members of the
Board of Directors, or, if the Company had a nominating committee at such time,
its nominating committee, immediately preceding such election; or (iii) the
Company effectuates a complete liquidation or a sale or disposition of all or
substantially all of its assets.

       (b)  A “Takeover Transaction” shall mean (i) a merger or consolidation of
the Company with, or an acquisition of the Company or all or substantially all
of its assets by, any other corporation or entity, other than a merger,
consolidation or acquisition in which the individuals who were members of the
Board of Directors of the Company immediately prior to such transaction continue
to constitute a majority of the Board of Directors or other governing body of
the surviving corporation or entity (or, in the case of an acquisition involving
a holding company, constitute a majority of the Board of Directors or other
governing body of the holding company) for a period of not less than twelve
(12) months following the closing of such transaction, or (ii) one or more
occurrences or events as a result of which any “person” (as such term is used in
Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”)), becomes the “beneficial owner” (as such term is defined
in Rule 13d-3 under the Exchange Act), directly or indirectly, of thirty percent
(30%) or more of the combined voting power of the Company’s then outstanding
securities.   
 
4. Option Exercise.

  4.1  The Option shall be exercised by delivering this Agreement for
endorsement to the Company, at its principal office, attention of the Corporate
Secretary, together with a Notice and Agreement of Exercise (in the form
attached hereto or specified from time to time by the Committee) indicating the
number of Option Shares Optionee wishes to purchase and full payment of the
Exercise Price of such shares. In no event shall the Company be required to
issue or transfer fractional shares.

4.2 Payment for Option Shares may be made in cash, by cashier’s or certified
check.

--------------------------------------------------------------------------------

5. Employment of Optionee.

5.1. Except as otherwise provided in paragraph 6 of this Agreement, Optionee may
not exercise the Option unless, at the time of exercise, Optionee is employed by
the Company or a parent or a subsidiary thereof and has been in the employ of
the Company or a parent or a subsidiary thereof continuously since the Effective
Date. For purposes of this paragraph, the period of continuous employment with
the Company shall be deemed to include (without extending the term of the
Option) any period during which Optionee is on leave of absence with the consent
of the Company, provided that such leave of absence shall not exceed three
months and Optionee returns to the employ of the Company at the expiration of
such leave of absence. If Optionee fails to return to the employ of the Company
at the expiration of such leave of absence, Optionee’s employment with the
Company shall be deemed terminated as of the date such leave of absence
commenced.

The continuous employment of Optionee with the Company shall also be deemed to
include any period during which Optionee is a member of the military, provided
that Optionee returns to the employ of the Company within 90 days (or such
longer period as may be prescribed by law) from the date Optionee first becomes
entitled to discharge. If Optionee does not return to the employ of the Company
within 90 days from the date Optionee first becomes entitled to discharge (or
such longer period as may be prescribed by law), Optionee’s employment with the
Company shall be deemed to have terminated as of the date Optionee’s military
service ended.

5.2 Nothing contained herein shall be construed to impose upon the Company or
subsidiary thereof any obligation to employ Optionee for any period or to
supersede or in any way alter, increase or diminish the respective rights and
obligations of the Company or any parent or subsidiary thereof and Optionee
under any employment contract now or hereafter existing between them.

6. Termination of Employment. 

6.1.  If the employment of Optionee with the Company shall terminate because of
Retirement, Disability (as such terms are defined in the Plan) or death, unless
otherwise provided
by the Committee (with the consent of Optionee) or otherwise expressly provided
herein, (a) the Option, to the extent then presently exercisable, shall remain
in full force and effect and may be exercised pursuant to the provisions hereof,
including expiration at the end of the fixed term hereof, and (b) the Option, to
the extent not then presently exercisable, shall terminate as of the date of
such termination of employment and shall not be exercisable thereafter.

6.2 If the employment of Optionee with the Company shall terminate for any
reason other than the reasons set forth in paragraph 6.1 hereof, unless
otherwise provided by the Committee, (a) the Option, to the extent then
presently exercisable, shall remain exercisable only for a period of ninety (90)
days after the date of such termination of employment and may be exercised
during such period pursuant to the provisions hereof, including expiration at
the end of the fixed term hereof, and (b) the Option, to the extent not then
presently exercisable, shall terminate as of the date of such termination of
employment and shall not be exercisable thereafter.

--------------------------------------------------------------------------------

 
7. Securities Laws Requirements. 

7.1 The Option shall not be exercisable unless and until any applicable
registration or qualification requirements of federal and state securities laws,
and all other requirements of law or any regulatory bodies having jurisdiction
over such exercise or issuance and delivery, have been fully complied with. The
Company will use reasonable efforts to maintain the effectiveness of a
Registration Statement under the Securities Act of 1933 (the “Securities Act”)
for the issuance of the Option and the Option Shares but there may be times when
no such Registration Statement will be currently effective. Exercise of the
Option may be temporarily suspended without liability to the Company during
times when no such Registration Statement is currently effective, or during
times when, in the reasonable opinion of the Committee, such suspension is
necessary to preclude violation of any requirements of applicable law or
regulatory bodies having jurisdiction over the Company. If the Option would
expire for any reason except the end of its term during such a suspension, then
if exercise of the Option is duly tendered before its expiration, the Option
shall be exercisable and exercised (unless the attempted exercise is withdrawn)
as of the first day after the end of such suspension. The Company shall have no
obligation to file any Registration Statement covering resales of the Option
Shares.

7.2. Upon each exercise of the Option, Optionee shall represent, warrant and
agree, by the Notice and Agreement of Exercise delivered to the Company, that
(a) no Option Shares will be sold or otherwise distributed in violation of the
Securities Act or any other applicable federal or state securities laws, (b) if
Optionee is subject to the reporting requirements under Section 16(a) of the
Exchange Act, Optionee will furnish to the Company a copy of each Form 4 or Form
5 filed by Optionee and will timely file all reports required under federal
securities laws, and (c) Optionee will report all sales of Option Shares to the
Company in writing on the form prescribed from time to time by the Company. All
Option Share certificates may be imprinted with legend
conditions reflecting federal and state securities law restrictions and
conditions and the Company may comply therewith and issue “stop transfer”
instructions to its transfer agents and registrars without liability.

8. Transferability of Option. The Option may not be transferred by Optionee
without the prior written consent of the Committee unless such transfer is
pursuant to a Will of Optionee or the laws governing the distribution of
Optionee’s property upon his or her death. The Option may be exercised, during
the lifetime of Optionee, only by Optionee and Optionee’s permitted transferees.
Notwithstanding the foregoing, the Option shall not be assignable by operation
of law and shall not be subject to attachment, execution, garnishment,
sequestration, the law of bankruptcy or any other legal or equitable process.
Any attempted assignment, transfer, pledge, hypothecation or other disposition
contrary to the provisions of this Agreement, and the levy of any execution,
attachment or similar process thereupon, shall be null and void and without
effect.

--------------------------------------------------------------------------------

 
9. Changes in Capitalization.

9.1 The number and class of shares subject to the Option, the Exercise Price
(but not the total price), and the minimum number of shares as to which the
Option may be exercised at any one time, shall be proportionately adjusted in
the event of any increase or decrease in the number of the issued shares of
Common Stock which results from a split-up or consolidation of shares, payment
of a stock dividend or stock dividends exceeding a total of two and one-half
percent (2.5%) for which the record dates occur in any one fiscal year, a
recapitalization (other than the conversion of convertible securities according
to their terms), a combination of shares or other like capital adjustment, so
that upon exercise of the Option, Optionee shall receive the number and class of
shares Optionee would have received had Optionee been the holder of the number
of shares of Common Stock for which the Option is being exercised upon the date
of such change or increase or decrease in the number of issued shares of the
Company.

9.2 Upon a reorganization, merger or consolidation of the Company with one or
more corporations as a result of which the Company is not the surviving
corporation, or in which the Company survives as a wholly-owned subsidiary of
another corporation, or upon a sale of all or substantially all of the property
of the Company to another corporation, or any dividend or distribution to
stockholders of more than 10% of the Company's assets, adequate adjustment or
other provisions shall be made by the Company or other party to such transaction
so that there shall remain and/or be substituted for the Option Shares provided
for herein, the shares, securities or assets which would have been issuable or
payable in respect of or in exchange for the Option Shares then remaining under
the Option, as if Optionee had been the owner of such shares as of the
applicable date. Any securities so substituted shall be subject to similar
successive adjustments.

10. Relationship.  The Option shall not be deemed to be salary or other
compensation to Optionee for purposes of any pension, thrift, profit sharing,
stock purchase or other employee benefit plan now maintained or hereafter
adopted by the Company.

11. Privileges of Ownership. Optionee shall not have any of the rights of a
stockholder with respect to the shares covered by the Option except to the
extent that share certificates have actually been issued and registered in
Optionee's name on the books of the Company or its registrar upon the due
exercise of the Option. The Company shall be allowed a reasonable time following
notice of exercise in which to accomplish the issuance and registration.

12. Reference to Plan. This Agreement and the Option are subject to all of the
terms and conditions of the Plan, which are hereby incorporated by reference. In
the event of any conflict between this Agreement and the Plan, the provisions of
the Plan shall prevail.
 
 
5

--------------------------------------------------------------------------------

 
13. Notices. Any notice to be given under the terms of this Agreement shall be
addressed to the Company in care of its Corporate Secretary at its principal
executive offices and any notice to be given to Optionee shall be addressed to
Optionee at the address appearing on the employment records of the Company, or
at such other address or addresses as either party may hereafter designate in
writing to the other. Any such notice shall be deemed duly given when personally
delivered or enclosed in a properly sealed envelope, addressed as herein
required and deposited, postage prepaid, in a post office or branch post office
regularly maintained by the jurisdiction in which it is deposited.

14. Withholding Taxes. The Company shall have the right at the time of exercise
of the Option to make adequate provision for any federal, state, local or
foreign taxes which it believes are or may be required by law to be withheld
with respect to such exercise ("Tax Liability"), to ensure the payment (through
withholding from Optionee's salary or the Option Shares or otherwise as the
Company shall deem in its sole and conclusive discretion to be in its best
interests) of any such Tax Liability.

15. Number and Gender. Terms used herein in any number or gender include other
numbers or genders, as the context may require.

16. Counterparts. This Agreement may be executed in one or more counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

 

6

--------------------------------------------------------------------------------

17. Governing Law. This Agreement and performance under it, shall be construed
in accordance with and under the laws of the State of Nevada, U.S.A. Should a
court or other body of competent jurisdiction determine that any term or
provision of this Agreement is excessive in scope, such term or provision shall
be adjusted rather than voided and interpreted so as to be enforceable to the
fullest extent possible, and all other terms and provisions of this Agreement
shall be deemed valid and enforceable to the fullest extent possible.

IN WITNESS WHEREOF, the Company and Optionee have executed this Agreement as of
the Effective Date.
