ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

      On March 28, 2002, Stratus Services Group, Inc. (the "Company") completed
the sale of the assets of its Engineering Services Division (the "Division") to
SEA Consulting Services Corporation (the "Purchaser") pursuant to the Asset
Purchase Agreement dated as of January 24, 2002 among the Company, SEP, LLC
("SEP"), Charles Sahyoun, Sahyoun Holdings LLC and the Purchaser. The
transaction was approved by a vote of the Company's stockholders at the
Company's annual meeting of stockholders held on March 28, 2002.

      The assets of the Division had been transferred to SEP, a limited
liability company in which the Company owns a 70% interest, at the time of the
execution of the Asset Purchase Agreement. Sahyoun Holdings, LLC, a company
wholly owned by Charles Sahyoun, the President of the Division and a
newly-elected director of the Company, owns the remaining 30% interest in SEP.

      Under the terms of the Asset Purchase Agreement, the Company received an
initial cash payment of $1,560,000, which represented 80% of the initial
$2,200,000 installment of the purchase price payable to SEP after the
satisfaction of certain liabilities and expenses of SEP. Sahyoun Holdings, LLC
received the other 20% of the initial net installment of the purchase price, or
$440,000.

      The Asset Purchase Agreement requires the Purchaser to make the following
additional payments to SEP:

(a)   A payment of $1 million, plus or minus the amount by which the Purchaser's
      profit for the six months ending June 30, 2002, as determined pursuant to
      the Asset Purchase Agreement, is greater or less than $600,000 (the
      "Second Payment");

(b)   A payment of $1 million, plus or minus the amount by which the Purchaser's
      profit for the six months ending December 31, 2002, as determined pursuant
      to the Asset Purchase Agreement, is greater or less than $600,000 (the
      "Third Payment");

(c)   Five subsequent annual payments (the "Subsequent Payments") which will be
      based upon a multiple of the annual successive increases, if any, in the
      Purchaser's profit during the five year period beginning on January 1,
      2003 and ending December 31, 2007.

      Pursuant to an allocation and indemnity agreement entered into by the
Company, Sahyoun Holdings, LLC and Mr. Sahyoun (the "Allocation and Indemnity
Agreement"), the Company is entitled to $250,000 of each of the Second Payment
and Third Payment. Sahyoun Holdings LLC and Mr. Sahyoun have guaranteed the
$250,000 payments to be made to the Company from each of the Second Payment and
Third Payment, regardless of the operating results of the Purchaser. Upon its
receipt of the payments required under the Allocation and Indemnity Agreement,
the Company's interest in SEP will terminate and the Company will not be
entitled to any additional payments under the Asset Purchase Agreement,
including the Subsequent Payments. Sahyoun Holdings LLC will be entitled to all
amounts paid to SEP under the Asset Purchase Agreement other than $500,000 of
payments payable to the Company pursuant to the Allocation and Indemnity
Agreement and guaranteed by Charles Sahyoun and Sahyoun Holdings, LLC as
described above. Under the terms of the Asset Purchase Agreement, Sahyoun
Holdings LLC will not be entitled to any Subsequent Payments or its allocable
share of the Second and Third Payments if Mr. Sahyoun's employment with
Purchaser ceases for any reason other than death or permanent disability prior
to December 31, 2003.

      Mr. Sahyoun and Sahyoun Holdings LLC have jointly and severally agreed to
indemnify the Company from and against all losses, damages, costs and expenses
arising out of or relating to (i) breaches of any covenants or agreements
required to be performed or complied with by Mr. Sahyoun or Sahyoun Holdings LLC
prior to the closing of the sale of the Division (the "Closing"); (ii) breaches
of any agreements, certificates, documents or instruments executed by Mr.
Sahyoun or Sahyoun Holdings LLC delivered pursuant to or in connection with the


                                       2
<Page>

Asset Purchase Agreement prior to or at Closing; (iii) the breach or fulfillment
of certain representations and warranties set forth in the Asset Purchase
Agreement; (iv) the negligence of the Company or the Division in conducting the
business of the Division, to the extent that any such losses related to a claim
of a party other than the Company; (v) illegal conduct or willful misconduct on
the part of the employees of the Division; and (vi) breaches prior to the
Closing of any contracts pertaining to the provision of engineering services by
the Division to a party other than the Company. The obligations of Mr. Sahyoun
and Sahyoun Holdings LLC to provide indemnity apply only to the extent that the
Company's losses are not covered by insurance.

      The Company has agreed to indemnify Mr. Sahyoun and Sahyoun Holdings LLC
from and against all losses, damages, costs and expenses arising out of or
related to (i) breaches of any covenants or agreements required to be performed
or complied with by the Company prior to the Closing, (ii) breaches of any
agreements, certificates, documents or instruments executed by the Company prior
to or at the Closing, and (iii) the breach or nonfulfillment of certain
representations and warranties set forth in the Asset Purchase Agreement.

      The Asset Purchase Agreement provides that Mr. Sahyoun will be entitled to
an annual salary of $175,000 from the Purchaser and, provided that the Purchaser
meets certain earnings tests, a bonus of $25,000 on each June 30 and December 31
during the term of his employment.

ITEM 5. OTHER EVENTS AND REGULATION FD DISCLOSURE

      In March 2002, the Company entered into an agreement with the holder (the
"Debenture Holder") of its outstanding 6% Convertible Debentures (the
"Debentures") pursuant to which it issued to the Debenture Holder 231,300 shares
of Series B Convertible Preferred Stock (the "Series B Preferred Stock") in
exchange for (i) $456,499 aggregate principal amount of Debentures, (ii) the
cancellation of a $400,000 promissory note previously issued by the Company to
the Debenture Holder and (iii) $300,000 in cash. In addition, the Debenture
Holder converted, between January 2002 and March 2002, $643,501 principal amount
of Debentures into 1,736,979 shares of Common Stock. As a result of these
transactions, there are no Debentures currently outstanding.

      The shares of Series B Preferred Stock have a stated value of $5 per
share. Holders of the Series B Preferred Stock are entitled to cumulative
dividends at a rate of 6% of the stated value per annum, payable when and as
declared by the Board of Directors. Dividends may be paid in cash or, at the
option of the Company, in shares of Common Stock, under certain circumstances.
Holders of Series B Preferred Stock are entitled to a liquidation preference of
$5.00 per share plus accrued dividends. The Series B Preferred Stock is
convertible into shares of Common Stock at the option of the holder at any time.
The number of shares of Common Stock into which each share of Series B
Convertible Preferred Stock is convertible is determined by dividing the
aggregate liquidation preference of the shares being converted by the lesser of
(i) $4.65 or (ii) 75% of the average closing price of the Common Stock during
the five (5) days preceding the date of conversion. If the Company's Common
Stock is reinstated for trading on the Nasdaq Stock Market, the Company will be
required to seek approval from its stockholders of a proposal to approve the
issuance of shares of Common Stock upon conversion of the Series B Preferred
Stock in excess of the limits imposed by the rules of the Nasdaq Stock Market.

      In addition to the transactions described above, in March 2002, the holder
of a $160,000 promissory note previously issued by the Company exchanged the
note for 32,000 shares of Series B Preferred Stock. Further, the Company and the
holders of the Company's Series A Preferred Stock agreed to an amendment of the
Certificate of Designation which will permit the Company to pay the redemption
price of the Series A Preferred Stock through the issuance of shares of the
Company's Common Stock. For purposes of determining the number of shares which
the Company will be required to issue if it chooses to pay the redemption price
in shares of Common Stock, the Common Stock will have a value equal to the
average closing price of the Common Stock during the five trading days
immediately preceding the date of redemption.

                Notes to Unaudited Pro Forma Financial Statements

(1)      Basis of Presentation

         The accompanying pro forma condensed balance sheet as of December 31,
         2001 and statement of operations for the year ended September 30, 2001
         and three months ended December 31, 2001 are presented to give effect
         to the sale of the assets of the Engineering Services Division ("SED")
         which occurred on March 28, 2002. The pro forma condensed balance sheet
         as of December 31, 2001 assumes that the sale occurred as of December
         31, 2001. The pro forma condensed statements of operations assume that
         the sale occurred October 1, 2000.

         The accompanying pro forma condensed balance sheet as of February 28,
         2002 is presented at the request of The Nasdaq Stock Market, Inc.
         ("Nasdaq") in connection with its consideration of the Company's appeal
         to reverse Nasdaq's previous determination to delist the Company's
         common stock from The Nasdaq SmallCap Market. This pro forma condensed
         balance sheet gives effect to the sale of the assets of SED which
         occurred on March 28, 2002 and certain other transactions that occurred
         in March 2002.

                  net of $199,610 of assets sold, resulting in a gain of
