Dear Joe:

      As an inducement for you to acquire a financial interest in Stratus
Services Group, Inc. (the "Company"), the Company hereby grants to you the
option (the "Option") to purchase all or any part of an aggregate of One Million
(1,000,000) shares (the "Shares") of its Common Stock, $.01 par value, after
giving effect to the proposed two-for-three reverse split (the "Reverse Split")
of the Company's Common Stock, on the terms and conditions hereinafter set
forth.

1. PURCHASE PRICE. The per share purchase price for the Shares of Common Stock
covered by this Option Agreement shall be equal to the public offering price of
one share of Common Stock in the initial public offering of the Common Stock
registered under the Securities Act of 1933, as amended.

2. TERM OF OPTION. The term of the Option shall be for a period of ten (10)
years from the date hereof (such date to be referred to herein as the
"Expiration Date"). The Option is subject to earlier termination as provided
herein.

3. VESTING OF OPTION. The Option shall vest and become exercisable in full only
after five (5) years or such time as the Company, after giving effect to the
Reverse Split, achieves earnings of $1.00 per basic share in a fiscal year, as
demonstrated by the Company's audited financial statements for such fiscal year.
The Option shall not be exercisable prior to vesting as provided above. To the
extent that the Option becomes exercisable, it may thereafter be exercised
either in whole or in part at any time prior to the expiration of the Option.

4. EXERCISE OF OPTION. Subject to the terms and provisions of this Option
Agreement, the Option may be exercised by written notice to the Company at its
executive office at 500 Craig Road, Manalapan, New Jersey, 07726, at any time
after it vests as provided in Section 3 above and until its expiration in
accordance with the terms hereof. Such notice shall state the

election to exercise the Option and the number of Shares in respect of which it
is being exercised. The notice shall be signed by the person exercising the
Option and shall be accompanied by payment in an amount equal to the aggregate
purchase price to be paid for the Shares purchased in cash or by cashier's check
made payable to the Company or such other form of payment as the Compensation
Committee of the Company's Board of Directors considers acceptable.

5. TERMINATION OF OPTION. If your employment with the Company:

           (i)        Terminates by reason of your voluntary resignation other
                      than for "Good Reason" or is terminated by the Company for
                      "Good Cause" (as the terms "Good Reason" and "Good Cause"
                      are defined in the Employment Agreement between you and
                      the Company dated September 1, 1997), the Option will
                      terminate upon the effective date of termination.

           (ii)       Terminates by reason of your death or disability (as such
                      term is defined in Section 22(e)(3) of the Internal
                      Revenue Code of 1986, as amended), the Option will
                      terminate upon the earlier of (a) the expiration of the
                      one (1) year period following the date of such termination
                      or (b) the Expiration.

           (iii)      Is terminated by the Company other than for Good Cause or
                      Good Reason, the Option will terminate upon the earlier of
                      (a) the expiration of the two (2) year period following
                      the date of such termination or (b) the Expiration.
