ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Registrant is incorporated under the laws of Delaware. Section 145 of
the Delaware General Corporation Law provides that a Delaware corporation may
indemnify any person against expenses, fines and settlements actually and
reasonably incurred by any such person in connection with a threatened, pending
or completed action, suit or proceeding in which he is involved by reason of the
fact that he is or was a director, officer, employee or agent of such
corporation, provided that (i) he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and (ii) with respect to any criminal action or proceeding, he had
no reasonable cause to believe his conduct was unlawful. If the action or suit
is by or in the name of the corporation, the corporation may indemnify any such
person against expenses actually and reasonably incurred by him in connection
with the defense or settlement of such action or suit if he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interest of the corporation, except that no indemnification may be made in
respect to any claim, issue or matter as to which such person shall have been
adjudged to be liable for negligence or misconduct in the performance of his
duty to the corporation, unless and only to the extent that the Delaware Court
of Chancery or the court in which the action or suit is brought determines upon
application that, despite the adjudication of liability but in light of the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the court deems proper.
 
     As permitted by the Delaware General Corporation Law, the Registrants'
Certificate of Incorporation provides that the directors and officers of the
Registrant shall be indemnified by the Registrant against certain liabilities
that those persons may incur in their capacities as directors or officers. The
Certificate of Incorporation eliminates the liability of directors of the
Registrant, under certain circumstances, to the maximum extent permitted by the
Delaware General Corporation Law. See "Description of Capital Stock -- Special
Provisions of the Certificate of Incorporation and By-laws" included in the
Prospectus.
 
     The Underwriting Agreement to be filed as Exhibit 1.1 hereto contains
reciprocal agreements of indemnity between the Registrant and the underwriters
as to certain liabilities, including liabilities under the Securities Act of
1933, as amended (the "Securities Act"), and in certain circumstances provides
for indemnification of the Registrant's directors and officers.
 
                                      II-1
<PAGE>   3
 
     Additionally, pursuant to an employment agreement between Mr. Silverman and
the Registrant and an employment agreement between Mr. McNairy and the
Registrant, the Registrant shall, to the maximum extent not prohibited by law,
indemnify Mr. Silverman and Mr. McNairy if Mr. Silverman or Mr. McNairy is made,
or threatened to be made, a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative, including an action by or in the right of the Registrant to
procure a judgment in its favor (collectively, a "Proceeding"), by reason of the
fact that Mr. Silverman or Mr. McNairy is or was a director or officer of the
Registrant, or is or was serving in any capacity at the request of the
Registrant for any other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against judgments, fines, penalties,
excise taxes, amounts paid in settlement and costs, charges and expenses
(including attorneys' fees and disbursements) paid or incurred in connection
with any such Proceeding. The Registrant anticipates that it may enter into
similar contractual indemnification arrangements with its other executive
officers and directors.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     During the previous three years, the Registrant has issued and sold the
following securities without registration under the Securities Act (none of
which sales were underwritten):
 
     The Company was formed in December 1996, at which time it issued 1,000 of
its shares of Common Stock for a cash purchase price of $1.00 per share to the
Selling Stockholder. Such issuance of shares was exempt from registration under
the Securities Act pursuant to Section 4(2) thereof as a transaction by the
issuer not involving any public offering.
 
     On May 22, 1997, the Company effected a stock split pursuant to which the
1,000 outstanding shares of Common Stock were subdivided into 3,400,000 shares
of Common Stock. All such shares were issued to the Selling Stockholder as sole
stockholder of the Company. Such issuance was exempt from registration under the
Securities Act pursuant to Section 3(a)(9) thereof as securities exchanged by
the issuer with its existing security holders exclusively where no commission or
other remuneration was given directly or indirectly for soliciting such
exchange.
 
     On July 23, 1997, Jay N. Silverman, President of the Company, purchased
25,000 shares of Common Stock from the Company at the initial public offering
price for a promissony note. This issuance of shares was exempt from
registration under the Securities Act pursuant to Section 4(2) thereof as a
transaction by the issuer not involving any public offering.
 
     Pursuant to an agreement dated June 2, 1997, contemporaneously with the
consummation of the Offering, the Company will issue an aggregate of 600,000
shares of Common Stock to Oliveira Limited, Dormera Limited, Balmedie Limited,
and Larlane Limited in exchange for the 81.0% of the outstanding shares of
Energy Research International owned by such entities. Gerald Harrison, George
Purdie, Neil Campbell, and David Burns, all of whom will be directors, officers
or employees of the Company after the consummation of the Offering, are the
beneficial owners of Oliveira Limited, Dormera Limited, Balmedie Limited, and
Larlane Limited, respectively. This issuance of shares will be exempt from
registration under the Securities Act pursuant to Section 4(2) thereof as a
transaction by the issuer not involving any public offering.

     (b) Financial Statement Schedules
 
     The following financial statement schedules are included in Part II of the
Registration Statement:
 
          None
 
     All other schedules are omitted because they are inapplicable or the
requested information is shown in the financial statements or noted therein.
 
ITEM 17. UNDERTAKINGS.
 
     (a) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     (b) The undersigned Registrant hereby undertakes to provide to the
representatives of the underwriters at the closing specified in the Underwriting
Agreement certificates in such denominations and registered in such names as
required by the representatives of the underwriters to permit prompt delivery to
each purchaser.
 
     (c) The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
                                      II-6
<PAGE>   8
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
     (d) If the Underwriters do not exercise their option to purchase additional
shares of Common Stock to cover over-allotments, if any, or if such option is
partially exercised, the Registrant hereby undertakes to file a post-effective
amendment to the Registration Statement deregistering all such shares as to
which such option shall not have been exercised.
