                        This Employment Agreement ("Agreement") is made by and between KFx Inc. ("Employer")
and Robert I. Hanfling ("Executive") (individually, a "party" and together, the "parties").  This Agreement shall be effective February 1, 2005.

            1.         Position.  Executive will begin employment with Employer on February 1, 2005, as President and
Chief Operating Officer. Executive's precise responsibilities and job description are subject to change at any time based on the discretion of the Employer's board of directors (the "Board").  Executive shall devote substantially full time and attention to the
business of the Employer during the term of this Agreement and shall perform all duties as may be required of him.

            2.         At-will Employment.  Executive and Employer expressly agree that Executive's employment with
Employer is "at-will," meaning that either Executive or Employer may terminate the employment relationship with or without cause and with or without notice at any time.  In the event that either Executive or the Employer terminates the employment relationship,
this Agreement shall also terminate, effective the same date as the termination of the employment relationship.  The at will nature of the employment relationship may only be modified in a writing signed by Executive and Employer's Chief Executive Officer, as
authorized by the Board.

            3.         Compensation.

                        3.1       Annual Salary.  Employer shall pay
to Executive an annual salary of $250,000.  Salary increases shall not be automatic, but instead shall be in the sole and absolute discretion of Employer's Board.

                        3.2       Bonus.  After Executive's first
year of employment, the Board shall grant Executive a guaranteed first-year bonus of $100,000.  Any subsequent bonuses are at the sole and absolute discretion of the Board.

                        3.3       Options.  The Board shall grant
stock options to the Executive pursuant to the terms and conditions of the stock option agreements attached hereto, and incorporated by reference herein, as Exhibit A; provided, that the grant of such options has been approved by the American Stock Exchange. 
The exercise price shall be the closing market price of Employer common stock on the date of grant by the Board.  The Board may, at its sole and absolute discretion, grant additional options from time to time.

                        3.4       Restricted Stock.  At the next
regular Board meeting, currently scheduled for March of 2005, the Board shall make a one-time only grant to the Executive of 100,000 shares of the Employer's restricted common stock from the Employer's 2002 Stock Incentive Plan to the extent that such shares are
available under such plan.  If 100,000 shares are not available under the 2002 Stock Incentive Plan, then the portion of the 100,000 shares of restricted stock that could not be granted under the 2002 Stock Incentive Plan shall be granted as an inducement grant
outside of the plan; provided, that the grant of such restricted stock has been approved by the American Stock Exchange.  Twenty percent of the restricted stock shall vest on

employed by the Employer on such dates.  The precise terms and conditions regarding the restricted stock grant shall be determined by the Board at or after the next regular Board meeting.  Executive shall sign such additional documents as requested by the
Board reflecting these terms and conditions.

            4.         Other Benefits.

                        4.1       Vacation.  Executive shall accrue
four weeks vacation each year.  The policies and rules regarding accrual and vesting are those set forth in Employer's Human Resources Policy & Procedures Manual.  Employer reserves the right to revise its policies and rules regarding accrual and
vesting of vacation.

                        4.2       Health Benefits.  Employer shall
offer Executive health benefits on the same terms that it offers benefits to other Executives.

                        4.3       Other Benefits.  With regard to
other benefits, Executive shall be entitled to those benefits on the same terms as Employer offers those benefits to regular, full-time Executives.

            5.         Relocation Expenses.  Employer will reimburse Executive with reasonable and customary expenses
associated with relocating from the Washington, DC area to Colorado.  Said expenses shall include moving expenses as well as temporary housing for up to six months, or for such longer period as Employer and Executive shall mutually agree.  Any such
reimbursement will be treated as taxable income as required by applicable state and federal law.

            6.         Nondisclosure of Confidential Information.  Executive acknowledges that the protection of
confidential or proprietary information and trade secrets (“Confidential Information”) is essential to the Employer.  To protect such information, Executive shall not, during the term of this Agreement or at any time thereafter, disclose any
Confidential Information that he may acquire in the performance of his duties to anyone outside of the Employer, except in accordance with the Company’s policies governing disclosure in the ordinary course of business and subject to a non-disclosure obligation
of the receiving party,  and will not use any Confidential Information for his own benefit or for the benefit of any third party, except as permitted by the Board or required by law.  He agrees that upon termination of employment, he will deliver promptly
to the Employer all memoranda, notices, records, reports, computer files, diskettes or other removable computer storage media, e-mail, and other documents (and copies thereof) relating to the business of the Employer, including but not limited to Confidential
Information, which he may then possess or have under his control.  Should Executive be compelled to disclose, by judicial or administrative process, any Confidential Information, he agrees that prior to disclosing such information, he will provide written notice
to the Employer as soon as practicable and, if possible, at least ten (10) days prior to producing such information.  Furthermore, Executive agrees to execute Employer's standard confidentiality, non-competition and inventions agreement.

-2-

            7.         Human Resources Policy and Procedures.  Executive agrees to review and abide by Employer's Human
Resources Policy & Procedures Manual.  Executive understands that Employer has the right to modify or rescind any policies in its Human Resource Manual, other than the policy regarding at-will employment, for any reason and with or without notice.

            8.         Executive Unrestricted by Other Agreements. Executive represents and warrants to the Employer that he
is not subject to any employment agreement, non-competition covenant, non-disclosure agreement or other agreement, covenant, understanding or restriction that would prohibit Executive from executing this Agreement and performing his duties and responsibilities
hereunder, or that would in any manner, directly or indirectly limit or adversely affect the duties and responsibilities which may now or in the future be assigned to Executive by the Employer.

            9.         General Provisions.

                        9.1       Governing Law and Forum.  This
Agreement shall be governed in accordance with the laws of the State of Colorado, without regard to its principles regarding conflicts of law.  Any disputes arising out of Executive's employment or this Agreement shall be brought in the City & County of
Denver, Colorado.

                        9.2       Severability.  If any provision in
this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions shall nevertheless continue in full force without being impaired or invalidated in any way.

                        9.3       Binding Effect; Assignability. 
This Agreement shall inure to the benefit of, and shall be binding upon, the parties hereto and their respective successors, assigns, heirs, and legal representatives.  The obligations of Executive hereunder are personal, and this Agreement may not be assigned
by Executive.

                        9.4       Entire Agreement.  This Agreement
and Exhibit A, attached, contain all of the terms agreed upon by the parties with respect to the subject matter of this Agreement, and supersede any and all prior agreements, arrangements, communications, understandings, documents or rules, either oral or in writing,
between the parties for the employment of Executive, and contain all of the covenants and agreements between the parties for such employment in any manner whatsoever.  Each party to this Agreement acknowledges that no representations, inducements, promises or
agreements, orally or otherwise, have been made by any party or anyone acting on behalf of any party which are not embodied in this Agreement.  Any modification of this Agreement will be effective only if in writing signed by Executive and Employer's Chief

 Participation, Development and Brokerage Rights

                        Section 2.1.  Investors’ Participation Rights
in Company Commercial Projects.  The Company hereby grants to the Investors the right to participate in Company Commercial Projects, subject to Section 2.7, Section 2.9, Section 4.1, Section 4.3 and the following terms and conditions:

	
          

	
                        (a)   After Total Production Capacity reaches or exceeds the Exempt
Capacity, the Investors shall have the right to participate in each new Company Commercial Project at a Participation Percentage up to fifteen percent (15%) of the Company’s Participation Percentage in such Company Commercial Project.  The Company may, in
its Discretion, offer the Investors a larger Participation Percentage on a per-project basis on whatever terms and conditions the Company in its Discretion elects to offer, and, unless otherwise provided by the terms of such additional participation, the additional
Investors Participation Percentage shall count towards Used Capacity; provided that the Investors shall be under no obligation to accept such an offer if presented.

	
          

	
	
          

	
                        (b)   Participation by the Investors in Company Commercial Projects
pursuant to this Section 2.1 will generally be on the same terms applicable to third parties, including the allocation of Development Costs, tax items, profits, losses and liabilities, provided, however, that the Investors shall not (i) be required

                        (c)   By way of example, if Total Production Capacity is more than the
Exempt Capacity and the Investors Project Rights have not terminated pursuant to Section 2.7, and the Company participates with a third party in a Commercial Project at a fifty percent (50%) Participation Percentage (prior to the Investors’ participation) with
an additional twenty-five percent (25%) Carried Interest, the Investors shall have the right to participate up to a seven and one-half percent (7.5%) Participation Percentage in such Commercial Project, without any adjustment for the Company’s Carried Interest

the Investors hereby covenants and agrees to, on behalf of itself and its Affiliates, and agrees to cause each of its Representatives, Affiliates and Affiliates’ Representatives to, coordinate with the Company in soliciting and negotiating with any potential
investors in a Investors Commercial Project or other related investment.

	
ARTICLE VIII

 Limited Liability; Exculpation

                        Section 8.1.  Exculpation.  In no
event shall the Company or any of its Subsidiaries be liable to any Investor, the Investor Representative or any other Person, whether in contract, tort or otherwise, for any loss, liability, cost, damage or other injury of any kind whatsoever, including any
consequential, incidental or special damages, including any lost profits or lost savings, even if the Company or its Affiliates or their respective Representatives have been advised of the possibility of such damages, suffered by any Investor in connection with
(i) any act, omission, appointment, resignation or removal of the Investors Representative, including because at any time there is no Investors Representative or because the Investor Representative is not entitled to receive any information pursuant to Section
2.7(d), or (ii) any act or omission of any Investor or third party.

	
ARTICLE IX

 Confidential Information.

                        Section 9.1.  Confidentiality.  Each
Investor and the Investor Representative hereby agrees not to use or disclose any Confidential Information except for (i) disclosure on a “need-to-know” basis to its Affiliates, its and its Affiliates’ Representatives and any prospective
assignee pursuant to ARTICLE VI, but only (A) for the express and limited purpose of discussing and evaluating potential participations by such Investor in Commercial Projects, or the potential assignment by such Investor of participation rights to such
prospective assignee, pursuant to this Agreement, and (B) in the case of disclosure to an Affiliate, any such Representative or any such prospective assignee, such Affiliate, Representative or prospective assignee covenants and agrees in writing, for the express
benefit of the Company, to (1) be bound by this ARTICLE IX, and (2) indemnify the Company for any breaches by such Affiliate, Representative or prospective assignee of its obligations under clause (1) next preceding, and such duly executed agreement is
delivered to the Company, (ii) disclosure or use with the prior

-27-

written consent of the Company or the Person which disclosed such Confidential Information, (iii) disclosure or use thereof after it has become a part of the public domain other than by reason of breach hereof by such
Investor or its Affiliates or any of their respective Representatives or prospective assignees, or (iv) disclosure pursuant to legal process or requirements of law, provided that to the extent practicable the Company shall be notified sufficiently in
advance of such requirement so that it may seek an appropriate protective order (or equivalent) with respect to such disclosure, with which such Investor shall, and shall cause its Affiliate, Representative or prospective assignee, fully to comply.  The Company shall use reasonable efforts to mark tangible Confidential Information as “confidential” and to confirm verbally disclosed Confidential Information as confidential in writing within thirty (30) days after the
oral disclosure, it being understood that a failure to do so does not constitute a designation of non-confidentiality, particularly when the confidential nature is apparent from the context and subject matter.

                        Section 9.2.  Company Project
Investors.  Without limiting the generality of Section 9.1, the names and identities of the Company’s proposed, prospective and actual sponsors, participants, partners or other investors (“Company Project Investors”) notified to
any Investor or the Investor Representative in connection with this Agreement or the transactions contemplated hereby shall be the proprietary and confidential property of the Company.  Each of the Investors hereby agrees to keep such Company Project Investors
confidential.

                        (d)   Its execution and delivery of this Agreement does not contravene
or conflict with its articles of incorporation, charter, partnership agreement, limited liability company agreement or other organizational or charter document, as applicable, or with any material agreement, contract or other instrument, or any law, rule, regulation,
order or decree, binding upon or applicable to it.

further understands that any such Commercial Project is likely to have additional restrictions or prohibitions against the sale or other Transfer of any interests in such Commercial Projects.

	
          

	
	
          

	
                        (e)   The Company has made available to it the opportunity to ask

ARTICLE XI

 Resolution of Disputes

                        Section
11.1.  Dispute Resolution.  All claims, controversies or disputes arising under, out of or in connection with or relation to this Agreement or the transactions contemplated hereby, whether
sounding in contract or tort or otherwise, including the interpretation or enforcement hereof,

-29-

arbitrability and any claim that this Agreement or the First Amendment was induced by fraud (the “Covered Claims”), shall be resolved in Denver, Colorado by mediation in accordance with Section 11.2 or,
failing that, by binding, non-appealable arbitration in accordance with Section 11.3.  All mediations and arbitrations pursuant to this Section 11.1 shall be conducted in English, and all documents, papers and other writings to be submitted
into evidence not originally in English shall be translated into English prior to their submission.

                        Section
11.2.  Mediation.  Any party may commence mediation of a Covered Claim by providing to Judicial Arbitration and Mediation Service (“JAMS”) and the other party a written request
for mediation in Denver, Colorado, setting forth the subject of the dispute and the relief requested.  The parties will cooperate with JAMS and with one another in selecting a mediator from JAMS panel of neutrals, and in scheduling the mediation
proceedings.  The parties covenant that they will participate in the mediation in good faith, and that they will share equally in its costs.  All offers, promises, conduct and statements, whether oral or written, made in the course of the mediation by any
of the parties, their agents, employees, experts and attorneys, and by the mediator or any JAMS employees, are confidential, privileged and inadmissible for any purpose, including impeachment, in any arbitration or other proceeding involving the parties, provided
that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation.  Either party may initiate arbitration pursuant to Section 11.3 with respect to the matters submitted to
mediation by filing a written demand for arbitration at any time following forty-five (45) days after the date of the initial mediation session.  The mediation may continue after the commencement of arbitration if the parties so desire.  Unless otherwise
agreed by the parties, the mediator shall be disqualified from serving as arbitrator in the case.  The provisions of this Section 11.2 may be enforced by any court of competent jurisdiction, and the party seeking enforcement shall be entitled to an award of all
costs, fees and expenses, including attorneys’ fees, to be paid by the party against whom enforcement is ordered.

                        Section 11.3.  Arbitration.  If the
parties are unable to resolve any Covered Claim by mediation pursuant to Section 11.2, they shall submit such Covered Claim to binding, non-appealable arbitration in Denver, Colorado, all in accordance with this Section 11.3.

	
          

	
                        (a)   Administrator.  The arbitration of all Covered Claims
will be administered by the American Arbitration Association, Inc., a New York not-for-profit corporation, together with its successors (the “Arbitration Administrator”).

	
          

	
	
          

	
                        (b)   Procedural Law.  Except as otherwise provided herein,
the arbitration of all Covered Claims will be governed by Colorado procedural law (including the rules of civil procedure, evidence and court (excluding local rules)) as if the Covered Claims had been brought in a District Court of the State of Colorado;
provided, however, that (i) the parties waive any right to jury, (ii) there shall be no appellate relief available, and (iii) discovery will be limited to matters which are directly relevant to the issues
in the arbitration.

	
          

	
	
          

	
                        (c)   Arbitrator.  The arbitration
shall be conducted by a single, neutral arbitrator (the “Arbitrator”) to be selected under this Section 11.3(c).  Within seven (7) business days from service of an arbitration complaint, the Company and Investors Representative will either
agree upon an Arbitrator or, failing such agreement, shall exchange lists containing the names of five (5) candidates proposed by each of them to serve in such capacity.

	
          

	
	
          

	
          

	
                        (1)   If any proposed candidate shall be common to both lists, that
individual shall serve as the Arbitrator (with the individual whose last name comes first alphabetically being chosen in case more than one individual is common to both lists).

	
          

	
          

	
	
-30-

 
	
          

	
          

	
                        (2)   If no proposed candidate shall be common to both lists, no later
than three (3) business days after such exchange of lists, the parties shall serve each other with a combined list comprised of the parties’ combined ten (10) proposed candidates, ranking each candidate in order of preference, with “1” being the
most preferred and “10” being the least preferred candidate.  The candidate with the lowest aggregate ranking shall serve as the Arbitrator (with the individual whose last name comes first alphabetically being chosen in case of a tie).

	
          

	
	
          

	
If any individual selected in accordance with the procedures provided in this Section 11.3(c) is at any time, including after the selection of the Arbitrator, unable or unwilling to act as the Arbitrator, the individual whose
ranking is next lowest shall be approached until an Arbitrator is selected.  If none of the candidates on the Combined List is capable or willing to serve as the Arbitrator, the Company and Investors Representative may either agree to repeat the process until an
Arbitrator is selected or, at the election of either of them, proceed in accordance with the then prevailing rules of the Arbitration Administrator regarding arbitrator selection.

	
          

	
	
          

	
                        (d)   Emergency Relief.  Applications for emergency relief
made prior to the appointment of the Arbitrator shall be made in accordance with the Arbitration Administrator’s Optional Rules for Emergency Measures of Protection.

	
          

	
	
          

	
                        (e)   Excluded Claims. 
“Covered Claims”, as used in this Agreement, shall not include compulsory or permissive cross-claims between or among the parties that arise in a legal action brought by or against a non-signatory hereto (each, a “Non-Signatory
Action”); provided, however, that a party that has the right to assert a permissive cross-claim against another party in a Non-Signatory Action may choose to treat that claim as a Covered Claim and assert it in accordance with the terms of
this Section 11.3(e).

	
          

	
	
          

	
                        (f)   Record and Proceedings.  A full stenographic or
electronic record of all proceedings in the arbitration shall be maintained, and the Arbitrator shall issue rulings, a statement of decisions and a judgment as if the Arbitrator were a sitting Judge of the District Court of the State of Colorado, with all of the
powers (including with respect to remedies) vested in such a judge.

	
          

	
	
          

	
                        (g)   Res Judicata, Collateral Estoppel and Law of the
Case.  A decision of the Arbitrator shall have the same force and effect with respect to collateral estoppel, res judicata and law of the case that such decision would have been entitled to if decided in a court of law, but in no event shall such a
decision be used by or against a party to this Agreement in a Non-Signatory Action.

	
          

	
	
          

	
                        (h)   Jurisdiction; Venue; Enforcement of Award.  The
parties hereto consent and submit to the exclusive personal jurisdiction and venue of the District Court and the Federal District Court, located in the County of Denver, State of Colorado, to compel arbitration of Covered Claims in accordance herewith, to enforce any
arbitration award granted pursuant hereto, including any award granting equitable relief, and to otherwise enforce this Agreement and carry out the intentions of the parties to resolve all Covered Claims through arbitration.

	
          

	
	
          

	
                        (i)   Confidentiality.  All
arbitration proceedings, including any appellate proceedings, will be closed to the public and confidential, and all records relating thereto will be permanently sealed, except as necessary to obtain court confirmation of the judgment of the Arbitrator and except as
necessary to give effect to res judicata and collateral estoppel (such as in a dispute between the parties to such arbitration proceedings that is not a Covered Claim), in

	
          

	
	
-31-

 
		
which case all filings with any court shall be sealed to the extent permissible by the court.  A party (including such party’s counsel or other representatives) may disclose to the media only the fact and generic
nature of a Covered Claim that is being, or has been, arbitrated pursuant hereto.  Nothing in this Section 11.3(i) is intended to, or shall, preclude a party from communicating with, or making disclosures to, its lawyers, tax advisors, auditors and insurers, as
necessary and appropriate, or from making such other disclosures as may be required by law.

	
 

	
	
          

	
                        (j)   Fees and Costs.  The Company and Investors shall split
equally the fees of the Arbitrator and the administrative costs of the arbitration.  All other costs associated with the arbitration, or any litigation to enforce any arbitration award granted pursuant hereto (including attorney’s fees and related costs),
shall be borne by the parties incurring such costs and expenses.

	
ARTICLE XII

and provisions of Section 3.3(b) (rights to Investors Improvements), ARTICLE VII (negative covenants), ARTICLE VIII (limited liability; indemnity), ARTICLE IX (confidentiality), ARTICLE XI (resolution of disputes) and Section 12.11 (jurisdiction and venue) shall
survive the termination of this Agreement.

                        Section 12.3.  Counterparts.  This Agreement may be executed
in one or more counterparts, each of which shall be deemed to constitute an original but all of which together shall constitute but one and the same instrument.

Waivers.  Any term of this Agreement may be amended, and the observance of any term hereof may be terminated or waived (either generally or in a particular instance and either retroactively or prospectively), but only with the written consent of the
Company and the Investors Representative; provided,however,that any amendment, termination or waiver (i) affecting any Investor in a manner substantially different (other than due to differences in the respective proportionate participation
of the Investors in the Investors Rights) than the Investors generally shall also require the written consent of such Investor, or (ii) amending, terminating or waiving this Section 12.4 shall require the written consent of all Investors.

                        Section 12.5.  Entire Agreement.  This Agreement and the
Investors’ Rights Agreement (including the Schedules thereto), as amended by the First Amendment, represents the entire agreement of the parties hereto with reference to the transactions contemplated hereby and supersede all prior negotiations, correspondence,

represents and agrees that neither it, nor any of its Affiliates, has made any representations, promises or statements to induce any other party to enter into this Agreement, and each party specifically disclaims reliance on any such representations, promises or
statements by any other party or any other party’s Affiliates and any rights arising therefrom.

-32-

                        Section 12.6.  No Third Party Beneficiaries.  Except as
provided in Section 8.2 (insofar as it provides any rights to the “Indemnified Persons” described therein), nothing in this Agreement, express or implied, is intended to confer upon any Person, other than the parties hereto or their respective successors
and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

                        Section 12.7.  Amendment of Investors’ Rights
Agreement.  To the extent, if any, it is determined that the First Amendment and this Agreement do not effectively amend the K‐Fuel Provisions for any parties to the Investors’ Rights Agreement that are not signatories hereto (such parties,
if any, the “Non-Signing Parties”), the rights granted to the Investors herein shall be (i) waived to the extent inconsistent with the rights granted by the K‐Fuel Provisions to the Non-Signing Parties, and (ii) proportionately
reduced for the Investors to the extent substantially similar rights are effectively exercised under the K‐Fuel Provisions by action of any Non-Signing Party.

                        Section 12.8.  Successors and Assigns.  All terms and
provisions of this Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns.

fullest extent permitted by applicable law, (i) any objection to the laying of venue of any such suit, action or proceeding brought in any such court, and (ii) any claim that any such suit, action or proceeding brought in any such court has been brought in
