ITEM 4. Description Of Securities.

         Not applicable.

ITEM 5. Interests Of Named Experts And Counsel.

         Not applicable.

ITEM 6. Indemnification Of Directors And Officers.

         Section 102 of the Delaware General Corporation Law, or DGCL, allows
a corporation, in its original certificate of incorporation or an amendment
thereto, to eliminate or limit the personal liability of a director for
violations of the director's fiduciary duty, except where the director
breached his duty of loyalty, failed to act in good faith, engaged in
intentional misconduct or knowingly violated a law, authorized the payment of
a dividend or approved a stock repurchase or redemption in violation of the
DGCL or obtained an improper personal benefit.

         Section 145 of the DGCL empowers a Delaware corporation to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of such corporation) by reason of the fact that such person is or was a
director, officer, employee or agent of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise.
The indemnity may include expenses (including attorney's fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding, provided that such
person acted in good faith and in a manner such person reasonably believed to
be in or not opposed to the best interests of the corporation and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe such person's conduct was unlawful. A Delaware corporation may
indemnify directors, officers, employees and other agents of such corporation
in an action by or in the right of a corporation under the same conditions
against expenses (including attorney's fees) actually and reasonably incurred
by the person in connection with the defense and settlement of such action or
suit, except that no indemnification is permitted without judicial approval if
the person to be indemnified has been adjudged to be liable to the
corporation. Where a present or former director or officer of the corporation
is successful on the merits or otherwise in the defense of any action, suit or
proceeding referred to above or in defense of any claim, issue or matter
therein, the corporation must indemnify such person against the expenses
(including attorneys' fees) which he or she actually and reasonably incurred
in connection therewith.

         Section 174 of the DGCL provides, among other things, that a director
who willfully or negligently approves of an unlawful payment of dividends or
an unlawful stock purchase or redemption, may be held liable for such actions.
A director who was either absent when the unlawful actions were approved or
dissented at the time, may avoid liability by causing his or her dissent to
such actions to be entered into the books containing the minutes of the
meetings of the board of directors at the time such action occurred or
immediately after such absent director receives notice of the unlawful acts.

         We have implemented indemnification provisions in our certificate of
incorporation, providing that officers and directors shall be entitled to be
indemnified by us to the fullest extent permitted by law against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
incurred in connection with any action, suit or proceeding by reason of the
fact that he or she is or was an officer or director of us.

         The above discussion of our certificate of incorporation and Sections
102, 145 and 174 of the DGCL is not intended to be exhaustive and is qualified
in its entirety by such certificate of incorporation and statutes.

         Under Section 145(g) of the DGCL, we maintain insurance on behalf of
the directors and officers serving at our request.

ITEM 9. Undertakings.

A.       Subsequent Disclosure.

         The undersigned Registrant hereby undertakes:

         (1)  To file, during any period in which offers or sales are being
              made, a post-effective amendment to this Registration
              Statement;

              (i)    To include any prospectus required by Section
                     10(a)(3) of the Securities Act;

             (ii)    To reflect in the prospectus any facts or events arising
                     after the effective date of this Registration Statement
                     (or the most recent post-effective amendment thereof)
                     which, individually or in the aggregate, represent a
                     fundamental change in the information set forth in this
                     Registration Statement. Notwithstanding the foregoing,
                     any increase or decrease in volume of securities offered
                     (if the total dollar value of securities offered would
                     not exceed that which was registered) and any deviation
                     from the low or high end of the estimated maximum
                     offering range may be reflected in the form of prospectus
                     filed with the Commission pursuant to Rule 424(b) if, in
                     the aggregate, the changes in volume and price represent
                     no more than 20 percent change in the maximum aggregate
                     offering price set forth in the "Calculation of
                     Registration Fee" table in the effective Registration
                     Statement; and

             (iii)   To include any material information with respect to the
                     plan of distribution not previously disclosed in this
                     Registration Statement or any material change to such
                     information in this Registration Statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii)
above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the Registrant, pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement.

      (2)   That, for the purpose of determining any liability under the
            Securities Act, each such post-effective amendment 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.

      (3)   To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.

B.   Incorporation By Reference.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in this Registration Statement 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.

C.   Commission Position On Indemnification.

         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 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.

         Pursuant to the requirements of the Securities Act of 1933, the

                 Re:  KFx Inc. Registration Statement on Form S-8

Ladies and Gentlemen:

         We have acted as special counsel for KFx Inc., a Delaware corporation
(the "Company"), in connection with the proposed issuance by the Company of up
to 2,000,000 shares (the "Shares") of common stock, par value $0.001 per share
(the "Common Stock"), pursuant to the Company's 2002 Stock Incentive Plan (the
"Plan").

         This opinion is being furnished in accordance with the requirements
of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as
amended (the "Securities Act").

         In connection with this opinion, we have examined originals or
copies, certified or otherwise identified to our satisfaction, of: (i) the
Company's Registration Statement on Form S-8 as filed with the Securities and
Exchange Commission (the "Commission") on the date hereof under the Securities
Act (together with all exhibits thereto, the "Registration Statement"); (ii)
the Restated Certificate of Incorporation of the Company, as amended to date
and currently in effect; (iii) the Second Amended and Restated By-Laws of the
Company, as amended to date and currently in effect; (iv) a specimen
certificate representing the Common Stock; (v) certain resolutions of the
Board of Directors of the Company; and (vi) the Plan. We have also examined
originals or copies, certified or otherwise identified to our satisfaction, of
such records of the Company and such agreements, certificates of public
officials, certificates of officers or other representatives of the Company
and others, and such other documents, certificates and records, as we have
deemed necessary or appropriate as a basis for the opinions set forth herein.

                  In our examination, we have assumed the legal capacity of
all natural persons, the genuineness of all signatures, the authenticity of
all documents submitted to us as originals, the conformity to original
documents of all documents submitted to us as certified, conformed or
photostatic copies and the authenticity of the originals of such latter
documents. In making our examination of executed documents, we have assumed
that the parties thereto had the power, corporate or other, to enter into and
perform all obligations thereunder and have also assumed the due authorization
by all requisite action, corporate or other, and execution and delivery by
such parties of such documents and the validity and binding effect thereof on
such parties. We have further assumed that all the Shares will be issued
pursuant to award agreements duly authorized by the Board of Directors of the
Company and validly executed and delivered by the parties thereto and that no
options will be granted under the Plan with per Share exercise prices below
the par value of the Common Stock. As to any facts material to the opinions
expressed herein which have not been independently established or verified, we
have relied upon statements and representations of officers and other
representatives of the Company and others.

         Members of our firm are admitted to the bar in the State of New York,
and we do not express any opinion as to the laws of any other jurisdiction
other than the General Corporation Law of the State of Delaware, and we do not
express any opinion as to the effect of any other laws on the opinion stated
herein.

         Based upon the foregoing and subject to the limitations,
qualifications, exceptions and assumptions set forth herein, we are of the
opinion that the issuance of the Shares has been duly authorized by the
Company, and when (a) certificates representing the Shares in the form of the
specimen certificate examined by us have been countersigned by an authorized
officer of the transfer agent and registrar of the Company's common stock (the
"Transfer Agent"), (b) the Shares have been registered by the Transfer Agent
on the stock record books of the Company, and (c) the Shares have been issued
and delivered by the Company, and the entire amount of the consideration
therefor has been received in full by the Company, in each case in accordance
with the terms of the Plan and the applicable award agreement, the Shares will
be validly issued, fully paid and nonassesable.

         We hereby consent to the filing of this opinion with the Commission
as an exhibit to the Registration Statement. We also consent to the reference
to our firm under the caption "Legal Matters" in the Registration Statement.
In giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Commission.

                                     Very truly yours,

                                     Skadden, Arps, Slate, Meagher & Flom LLP
