ITEM 5.    OTHER EVENTS.

         On May 31, 2001, Metretek Technologies, Inc., a Delaware corporation
(the "Company"), together with its wholly-owned subsidiaries Metretek,
Incorporated, a Florida corporation ("Metretek Florida"), and Southern Flow
Companies, Inc., a Delaware corporation ("Southern Flow"), along with Sigma VI,
Inc., a Florida corporation and Metretek Florida's wholly-owned subsidiary
("Sigma VI"), as pledgor, entered into a Sixth Amendment (the "Amendment") to
the Loan and Security Agreement, dated as of April 14, 1998 (the "Loan
Agreement"), between the Company, Metretek Florida, Southern Flow and Sigma VI
with National Bank of Canada, a Canadian chartered bank (the "Lender"). The
Amendment extends the "Maturity Date" of the Loan Agreement until September 30,
2001, subject to earlier termination upon (i) the occurrence of any default
under the Loan Agreement, (ii) the failure of the Company to perform its
obligations under the Amendment, (iii) an event that, with notice of the passage
of time or both, constitutes an "Event of Default" under the Loan Agreement or
any other agreement or (iv) a default in the Company's obligation to pay
interest. The Amendment facilitates a mutual agreement by the parties to
terminate their relationship and the Loan Agreement.

         The Amendment, a copy of which is filed as an exhibit hereto, amends
certain provisions in the Loan Agreement, including (i) reducing the maximum
available amount of loan availability from $5 million to $3 million; (ii)
increasing the rate of interest by one percent (1%); (iii) modifying the minimum
tangible net worth covenant to not less than $5,387,000, counting all approved
subordinate debt and Series B Preferred Stock as equity; (iv) requiring the
Company, on a consolidated basis, to maintain a positive net profit before
taxes, preferred stock dividends, depreciation, amortization, extraordinary
gains and income from cancellation of debt; and (v) waiving the requisite 2 to 1
ratio of consolidated earnings before interest, taxes, depreciation,
amortization and extraordinary gains to interest expense for the period ending
March 31, 2001.

         The Company intends to pay off the balance of the Loan Agreement and
terminate the credit facility by no later than the Maturity Date, and has made a
refinancing commitment in the Amendment to that effect. In lieu of refinancing
the Loan Agreement with a similar agreement with a third party, the Company may
also seek to raise additional funds from the proceeds of public or private
financings, debt financings or other sources. The Company may seek additional
capital funds through financing at the parent or the subsidiary level, depending
upon the availability of capital, market conditions, its consolidated operations
and operations of that subsidiary. In addition, if the Company raises additional
capital by issuing capital stock or securities convertible into convertible
stock, stockholders could suffer here dilution of represented ownership
interest, and the new capital stock or other securities could have rights,
preferences or privileges senior to those of our current stockholders. Depending
on how it is structured, any capital raising could require the consent of the
holders of the Company's B Preferred Stock.

         The Company fully expects to be able to arrange for the refinancing
and/or repayment and termination of the Loan Agreement by the Maturity Date.
However, it cannot provide absolute assurance that it will be able to replace
its current credit facility. Nor can it provide absolute assurance that
sufficient additional funds can be obtained on terms satisfactory to its Series
B Preferred Stock, if their consents are required. The Company's inability to
obtain sufficient additional capital on a timely basis on terms that are
acceptable could have a material adverse effect on the Company's business,
financial condition and results of operations.
