                            INDEMNIFICATION AGREEMENT
                            -------------------------

         This Agreement is made as of this ___ day of _________ ("Agreement"),
by and between Metretek Technologies, Inc., a Delaware corporation (the
"Company," which term shall include, where appropriate, any Entity (as
hereinafter defined) controlled directly or indirectly by the Company), and
______________ ("Indemnitee").

         WHEREAS, it is essential to the Company that it be able to retain and
attract as directors the most capable persons available;

         WHEREAS, increased corporate litigation has subjected directors to
litigation risks and expenses, and the limitations on the availability of
directors and officers liability insurance have made it increasingly difficult
for the Company to attract and retain such persons;

         WHEREAS, the Company's Restated Certificate of Incorporation and
Amended and Restated By-laws permit it to indemnify its directors to the fullest
extent permitted by law and permit it to make other indemnification arrangements
and agreements;

         WHEREAS, the Company desires to provide Indemnitee with specific
contractual assurance of Indemnitee's rights to full indemnification against
litigation risks and expenses (regardless of, among other things, any amendment
to or revocation of such Certificate of Incorporation or By-laws or any change
in the ownership of the Company or the composition of its Board of Directors);
and

         WHEREAS, Indemnitee is relying upon the rights afforded under this
Agreement in becoming a director of the Company.

         NOW, THEREFORE, in consideration of the promises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:

and commitments hereunder, Indemnitee agrees to serve or continue to serve as a

         indemnified by the Company against all Expenses and Liabilities
         incurred or paid by Indemnitee in connection with such Proceeding

         Liabilities," respectively, and collectively as "Indemnifiable
         Amounts").

                                       2
<PAGE>   3
                  (b) Subject to the exceptions contained in Section 4(b) below,
         if Indemnitee was or is a party or is threatened to be made a party to
         any Proceeding by or in the right of the Company to procure a judgment
         in its favor by reason of Indemnitee's Corporate Status, Indemnitee
         shall be indemnified by the Company against all Indemnifiable Expenses.

                  (c) Notwithstanding the foregoing, the Company shall not be
         obligated to pay the Indemnitee for Expenses or Liabilities to the
         extent the Company's Officers' and Directors' Insurance Carrier has
         already paid the Indemnitee such amounts pursuant to the Company's
         Officers' and Directors' Liability Insurance Policy.

         4. Exceptions to Indemnification. Indemnitee shall be entitled to
indemnification under Sections 3(a) and 3(b) above in all circumstances other
than the following:

                  (a) If indemnification is requested under Section 3(a) and it
         has been adjudicated finally by a court of competent jurisdiction that,
         in connection with the subject of the Proceeding out of which the claim
         for indemnification has arisen, Indemnitee failed to act (i) in good
         faith and (ii) in a manner Indemnitee reasonably believed to be in or
         not opposed to the best interests of the Company, or, with respect to
         any criminal action or proceeding, Indemnitee had reasonable cause to
         believe that Indemnitee's conduct was unlawful, Indemnitee shall not be
         entitled to payment of Indemnifiable Amounts hereunder.

                  (b) If indemnification is requested under Section 3(b) and

                           (i) it has been adjudicated finally by a court of
                  competent jurisdiction that, in connection with the subject of
                  the Proceeding out of which the claim for indemnification has
                  arisen, Indemnitee failed to act (A) in good faith and (B) in
                  a manner Indemnitee reasonably believed to be in or not
                  opposed to the best interests of the Company, Indemnitee shall
                  not be entitled to payment of Indemnifiable Expenses
                  hereunder; or

                           (ii) it has been adjudicated finally by a court of
                  competent jurisdiction that Indemnitee is liable to the
                  Company with respect to any claim, issue or matter involved in
                  the Proceeding out of which the claim for indemnification has
                  arisen, including, without limitation, a claim that Indemnitee
                  received an improper personal benefit, no Indemnifiable
                  Expenses shall be paid with respect to such claim, issue or
                  matter unless the Court of Chancery or another court in which
                  such Proceeding was brought shall determine upon application
                  that, despite the adjudication of liability, but in view of
                  all the circumstances of the case, Indemnitee is fairly and
                  reasonably entitled to indemnity for such Indemnifiable
                  Expenses which such court shall deem proper.

                  (c) Any other provision herein to the contrary
         notwithstanding, the Company shall not be obligated pursuant to the
         terms of this Agreement:

                           (i) To indemnify or advance Expenses to the
                  Indemnitee with respect to Proceedings initiated or brought
                  voluntarily by the Indemnitee and not by way of defense,
                  EXCEPT with respect to Proceedings specifically authorized by
                  the Board or brought to

                                       3
<PAGE>   4
                  establish or enforce a right to indemnification and/or
                  advancement of Expenses arising under this Agreement, the
                  charter or bylaws of the Company or any subsidiary or any
                  statute or otherwise;

                           (ii) To indemnify the Indemnitee hereunder for any
                  amounts paid in settlement of a Proceeding unless the Company
                  consents in advance in writing to such settlement, which
                  consent shall not be unreasonably withheld; or

                           (iii) To indemnify the Indemnitee for Liabilities in
                  connection with a judgment against the Indemnitee on a claim
                  for an accounting of profits made from the purchase or sale by
                  the Indemnitee of securities of the Company pursuant to the
                  provisions of Section 16(b) of the Securities Exchange Act of
                  1934, as amended.

         5. Procedure for Payment of Indemnifiable Amounts. Indemnitee shall
submit to the Company a written request specifying the Indemnifiable Amounts for
which Indemnitee seeks payment under Section 3 of this Agreement and the basis
for the claim. The Company shall pay such Indemnifiable Amounts to Indemnitee
within twenty (20) calendar days of receipt of the request. At the request of
the Company, Indemnitee shall furnish such documentation and information as are
reasonably available to Indemnitee and necessary to establish that Indemnitee is
entitled to indemnification hereunder.

         6. Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provision of this Agreement, and without
limiting any such provision, to the extent that Indemnitee is, by reason of
Indemnitee's Corporate Status, a party to and is successful, on the merits or
otherwise, in any Proceeding, Indemnitee shall be indemnified against all
Expenses reasonably incurred by Indemnitee or on Indemnitee's behalf in
connection therewith. If Indemnitee is not wholly successful in such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than
all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses reasonably incurred by Indemnitee or on
Indemnitee's behalf in connection with each successfully resolved claim, issue
or matter. For purposes of this Agreement, the termination of any claim, issue
or matter in such a Proceeding by dismissal, with or without prejudice, shall be
deemed to be a successful result as to such claim, issue or matter.

         7. Effect of Certain Resolutions. Neither the settlement or termination
of any Proceeding nor the failure of the Company to award indemnification or to
determine that indemnification is payable shall create an adverse presumption
that Indemnitee is not entitled to indemnification hereunder. In addition, the
termination of any proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent shall not create a presumption
that Indemnitee did not act in good faith and in a manner which Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company
or, with respect to any criminal action or proceeding, had reasonable cause to
believe that Indemnitee's action was unlawful.

         8. Agreement to Advance Expenses; Conditions. The Company shall pay to
Indemnitee all Indemnifiable Expenses incurred by Indemnitee in connection with
any Proceeding, including a Proceeding by or in the right of the Company, in
advance of the final

                                       4
<PAGE>   5
disposition of such Proceeding. To the extent required by Delaware law,
Indemnitee hereby undertakes to repay the amount of Indemnifiable Expenses paid
to Indemnitee if it is finally determined by a court of competent jurisdiction
that Indemnitee is not entitled under this Agreement to indemnification with
respect to such Expenses. This undertaking is an unlimited general obligation of
Indemnitee.

         9. Procedure for Advance Payment of Expenses. Indemnitee shall submit
to the Company a written request specifying the Indemnifiable Expenses for which
Indemnitee seeks an advancement under Section 8 of this Agreement, together with
documentation evidencing that Indemnitee has incurred such Indemnifiable
Expenses. Payment of Indemnifiable Expenses under Section 8 shall be made no
later than twenty (20) calendar days after the Company's receipt of such
request.

         10. Remedies of Indemnitee.

                  (a) Right to Petition Court. In the event that Indemnitee
         makes a request for payment of Indemnifiable Amounts under Sections 3
         and 5 above or a request for an advancement of Indemnifiable Expenses
         under Sections 8 and 9 above and the Company fails to make such payment
         or advancement in a timely manner pursuant to the terms of this
         Agreement, Indemnitee may petition the Court of Chancery to enforce the
         Company's obligations under this Agreement.

                  (b) Burden of Proof. In any judicial proceeding brought under
         Section 10(a) above, the Company shall have the burden of proving that
         Indemnitee is not entitled to payment of Indemnifiable Amounts
         hereunder.

                  (c) Expenses. The Company agrees to reimburse Indemnitee in
         full for any Expenses incurred by Indemnitee in connection with
         investigating, preparing for, litigating, defending or settling any
         action brought by Indemnitee under Section 10(a) above, or in
         connection with any claim or counterclaim brought by the Company in
         connection therewith.

                  (d) Validity of Agreement. The Company shall be precluded from
         asserting in any Proceeding, including, without limitation, an action
         under Section 10(a) above, that the provisions of this Agreement are
         not valid, binding and enforceable or that there is insufficient
         consideration for this Agreement and shall stipulate in court that the
         Company is bound by all the provisions of this Agreement.

                  (e) Failure to Act Not a Defense. The failure of the Company
         (including its Board of Directors or any committee thereof, independent
         legal counsel or stockholders) to make a determination concerning the
         permissibility of the payment of Indemnifiable Amounts or the
         advancement of Indemnifiable Expenses under this Agreement shall not be
         a defense in any action brought under Section 10(a) above, and shall
         not create a presumption that such payment or advancement is not
         permissible.

         11. Defense of the Underlying Proceeding.

                                       5
<PAGE>   6
                  (a) Notice by Indemnitee. Indemnitee agrees to notify the
         Company promptly upon being served with any summons, citation,
         subpoena, complaint, indictment, information, or other document
         relating to any Proceeding which may result in the payment of
         Indemnifiable Amounts or the advancement of Indemnifiable Expenses
         hereunder; provide, however, that the failure to give any such notice
         shall not disqualify Indemnitee from the right to receive payments of
         Indemnifiable Amounts or advancements of Indemnifiable Expenses unless
         the Company's ability to defend in such Proceeding is materially and
         adversely prejudiced thereby.

                  (b) Defense by Company. Subject to the provisions of the last
         sentence of this Section 11 (b) and of Section 11 (c) below, the
         Company shall have the right to defend Indemnitee in any Proceeding
         which may give rise to the payment of Indemnifiable Amounts hereunder;
         provided, however that the Company shall notify Indemnitee of any such
         decision to defend within ten (10) days of receipt of notice of any
         such Proceeding under Section 11 (a) above. The Company shall not,
         without the prior written consent of Indemnitee, consent to the entry
         of any judgment against Indemnitee or enter into any settlement or
         compromise which (i) includes an admission of fault of Indemnitee or
         (ii) does not include, as an unconditional term thereof, the full
         release of Indemnitee from all liability in respect of such Proceeding,
         which release shall be in form and substance reasonably satisfactory to
         Indemnitee. This Section 1l(b) shall not apply to a Proceeding brought
         by Indemnitee under Section 10(a) above or pursuant to Section 19
         below.

                  (c) Indemnitee's Right to Counsel. Notwithstanding the
         provisions of Section 11 (b) above, if in a Proceeding to which
         Indemnitee is a party by reason of Indemnitee's Corporate Status,
         Indemnitee reasonably concludes that it may have separate defenses or
         counterclaims to assert with respect to any issue which may not be
         consistent with the position of other defendants in such Proceeding, or
         if the Company fails to assume the defense of such proceeding in a
         timely manner, Indemnitee shall be entitled to be represented by
         separate legal counsel of Indemnitee's choice at the expense of the
         Company. In addition, if the Company fails to comply with any of its
         obligations under this Agreement or in the event that the Company or
         any other person takes any action to declare this Agreement void or
         unenforceable, or institutes any action, suit or proceeding to deny or
         to recover from Indemnitee the benefits intended to be provided to
         Indemnitee hereunder, Indemnitee shall have the right to retain counsel
         of Indemnitee's choice, at the expense of the Company, to represent
         Indemnitee in connection with any such matter.

         12. Representations and Warranties of the Company. The Company hereby
represents and warrants to Indemnitee as follows:

                  (a) Authority. The Company has all necessary power and
         authority to enter into, and be bound by the terms of, this Agreement,
         and the execution, delivery and performance of the undertakings
         contemplated by this Agreement have been duly authorized by the
         Company.

                  (b) Enforceability. This Agreement, when executed and
         delivered by the Company in accordance with the provisions hereof,
         shall be a legal, valid and binding obligation of the Company,
         enforceable against the Company in accordance with its terms, except as
         such

                                       6
<PAGE>   7
         enforceability may be limited by applicable bankruptcy, insolvency,
         moratorium, reorganization or similar laws affecting the enforcement of
         creditors' rights generally.

         13. Insurance. The Company shall, from time to time, make the good
faith determination whether or not it is practicable for the Company to obtain
and maintain a policy or policies of insurance with a reputable insurance
company providing Indemnitee with coverage for losses from wrongful acts, and to
ensure the Company's performance of its indemnification obligations under this
Agreement. Among other considerations, the Company will weigh the costs of
obtaining such insurance coverage against the protection afforded by such
coverage. In all policies of director and officer liability insurance,
Indemnitee shall be named as an insured in such a manner as to provide
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's officers and directors. Notwithstanding the foregoing,
the Company shall have no obligation to obtain or maintain such insurance if the
Company determines in good faith that such insurance is not reasonably
available, if the premium costs for such insurance are disproportionate to the
amount of coverage provided, or if the coverage provided by such insurance is
limited by exclusions so as to provide an insufficient benefit. The Company
shall promptly notify Indemnitee of any good faith determination not to provide
such coverage.

         14. Contract Rights Not Exclusive. The rights to payment of
Indemnifiable Amounts and advancement of Indemnifiable Expenses provided by this
Agreement shall be in addition to, but not exclusive of, any other rights which
Indemnitee may have at any time under applicable law, the Company's By-laws or
Certificate of Incorporation, or any other agreement, vote of stockholders or
directors (or a committee of directors), or otherwise, both as to action in
Indemnitee's official capacity and as to action in any other capacity as a
result of Indemnitee's serving as a director of the Company.

         15. Successors. This Agreement shall be (a) binding upon all successors
and assigns of the Company (including any transferee of all or a substantial
portion of the business, stock and/or assets of the Company and any direct or
indirect successor by merger or consolidation or otherwise by operation of law)
and (b) binding on and shall inure to the benefit of the heirs, personal
representatives, executors and administrators of Indemnitee. This Agreement
shall continue for the benefit of Indemnitee and such heirs, personal
representatives, executors and administrators after Indemnitee has ceased to
have Corporate Status.

         16. Subrogation. In the event of any payment of Indemnifiable Amounts
under this Agreement, the Company shall be subrogated to the extent of such
payment to all of the rights of contribution or recovery of Indemnitee against
other persons, and Indemnitee shall take, at the request of the Company, all
reasonable action necessary to secure such rights, including the execution of
such documents as are necessary to enable the Company to bring suit to enforce
such rights.

         17. Change in Law. To the extent that a change in Delaware law (whether
by statute or judicial decision) shall permit broader indemnification or
advancement of expenses than is provided under the terms of the By-laws of the
Company and this Agreement, Indemnitee shall

                                       7
<PAGE>   8
be entitled to such broader indemnification and advancements, and this Agreement
shall be deemed to be amended to such extent.

         18. Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Agreement, or any clause thereof,
shall be determined by a court of competent jurisdiction to be illegal, invalid
or unenforceable, in whole or in part, such provision or clause shall be limited
or modified in its application to the minimum extent necessary to make such
