                          ALPHA NATURAL RESOURCES, INC.

                                 PROMISSORY NOTE

                                                               February __, 2005

       FOR VALUE RECEIVED, ALPHA NATURAL RESOURCES, INC., a Delaware corporation
(the "COMPANY"), hereby promises to pay to the order of [_____________], or its
successors and registered assignee (the "HOLDER"), in lawful money of the United
States of America, the principal sum of $[______________] (the "ORIGINAL
PRINCIPAL AMOUNT"), as adjusted pursuant to Section 1(b) of this Note, or such
lesser amount as shall equal the unpaid principal amount of this Note (the
"PRINCIPAL AMOUNT"), together with interest, on the date and in the manner set
forth below.

       This Note is subject to the following terms and conditions:

       1.   INTERNAL RESTRUCTURING; ADJUSTMENT TO PRINCIPAL AMOUNT.

            (a) INTERNAL RESTRUCTURING. This Note is one of a series of
Promissory Notes of the Company (the "INTERNAL RESTRUCTURING NOTES") issued
pursuant to that certain Internal Restructuring Agreement dated as of February
__, 2005 among the Company, Alpha NR Ventures, Inc., ANR Holdings, LLC, the "FRC
Parties" (as defined therein), the "AMCI Parties" (as defined therein), Madison
Capital Funding LLC, Alpha Coal Management, LLC, and the "Management Members"
(as defined therein) (the "INTERNAL RESTRUCTURING AGREEMENT"). To the extent any
provision of this Note conflicts with the express provisions of the Internal
Restructuring Agreement, the provisions of the Internal Restructuring Agreement
shall govern and be controlling.

            (b) ADJUSTMENT TO PRINCIPAL AMOUNT. The Principal Amount of this
Note will be automatically increased by (A) the amount, if any, by which the
"Actual Net Proceeds" (as defined below) exceeds the "Estimated Net Proceeds"
(as defined below), multiplied by (B) a fraction, the numerator of which is the
Original Principal Amount and the denominator of which is the Estimated Net
Proceeds. The Principal Amount of this Note will be automatically decreased by
(Y) the amount, if any, by which the Estimated Net Proceeds exceeds the Actual
Net Proceeds, multiplied by (Z) a fraction, the numerator of which is the
Original Principal Amount and the denominator of which is the Estimated Net
Proceeds. Any adjustment to the Principal Amount pursuant to this Section 1(b)
will be effective as of the original issue date of this Note for all purposes
hereunder, including calculation of interest due under Section 3 of this Note.

            (c) DEFINITIONS. The term "ESTIMATED NET PROCEEDS" means $[_____].
The term "ACTUAL NET PROCEEDS" means (A) the proceeds received by the Company,
net of underwriting discounts and offering expenses, in the initial public
offering (the "IPO") of the Company's
<PAGE>

common stock registered on the Company's registration statement on Form S-1
(File No. 333-121002) originally filed with the Securities and Exchange
Commission on December 6, 2004, as amended from time to time, minus (B) the
amount of all accrued interest on this Note paid or payable by the Company to
the Holder pursuant to this Note.

       2. PAYMENT OF PRINCIPAL AMOUNT; MATURITY DATE. The Principal Amount of
this Note shall mature and be payable on the earliest to occur (the "MATURITY
DATE") of (i) three (3) business days after written demand therefore is made by
the Holder to the Company, and (ii) the first date that the Company receives
proceeds from the IPO. The Company may prepay this Note, in whole or in part, at
any time or from time to time prior to the Maturity Date without penalty or
premium.

       3. COMPUTATION AND PAYMENT OF INTEREST. Interest on the Principal Amount
from time to time remaining unpaid on this Note shall accrue from the original
issue date of this Note at the rate of [___] percent ([__]%) per annum
(calculated on the basis of a 365 day year) (the "BASE RATE")1 and shall be
payable on the Maturity Date or earlier repayment of this Note. Past-due
Principal Amount (and, to the extent permitted by applicable law, past-due
interest) shall bear interest at a rate equal to the Base Rate plus two percent
(2%) per annum.

       4. PLACE, MANNER AND APPLICATION OF PAYMENTS. All amounts payable under
this Note shall be payable to the Holder at the address for notice set forth in
the Internal Restructuring Agreement, or such other address as the Holder may
specify to the Company in writing, in immediately available United States funds.
All payments on this Note shall be applied first to accrued interest and
thereafter to the outstanding Principal Amount balance hereof.

      5. INTEREST SAVINGS CLAUSE. Notwithstanding any provision to the contrary
contained in this Note, neither the Company shall be required to pay, nor the
Holder shall be permitted to collect, any amount of interest in excess of the
maximum amount of interest permitted by law ("EXCESS INTEREST"). If any Excess
Interest is provided for or determined by a court of competent jurisdiction to
have been provided for in this Note, then in such event: (a) the provisions of
this Section 5 shall govern and control; (b) the Company shall not be obligated
to pay any Excess Interest; (c) any Excess Interest that the Holder may have
received under this Note shall be, at the Holder's option and to the extent
permitted by applicable law, (i) deemed a prepayment of the outstanding
Principal Amount of this Note, (ii) promptly refunded to the Company, or (iii)
any combination of the foregoing, as necessary to avoid violation of any
applicable usury statute; (d) the interest rate provided for in this Note shall
be automatically reduced to the maximum lawful rate allowed from time to time
under applicable law (the "MAXIMUM RATE"), and this Note shall be deemed to have
been and shall be, reformed and modified to reflect such reduction; and (e) the
Company shall not have any action against the Holder for any damages arising out
of the payment or collection of any Excess Interest. Notwithstanding the
foregoing, if for any period of time interest on the outstanding indebtedness
under this Note is calculated at the Maximum Rate rather than the applicable
rate under this

-------------

      federal rate for federal income tax purposes on the original issue date of
      the Note.
<PAGE>
Note, and thereafter such applicable rate becomes less than the Maximum Rate,
the rate of interest payable on the indebtedness under this Note shall remain at
the Maximum Rate until the Holder shall have received the amount of interest
which such Holder would have received during such period on such indebtedness
had the rate of interest not been limited to the Maximum Rate during such
period.

       6.    MISCELLANEOUS.

            (a) GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE.

 delivery or by facsimile transmission or mail. The person sending any notice
 shall prepay all transmission charges. Any notice personally delivered or given
 by mail shall be deemed effective upon receipt. Transmission by a recognized
 courier service shall be deemed personal delivery and any notice so delivered
 shall be deemed received at the time of delivery confirmed by the courier
 service. Any notice sent by facsimile transmission shall be deemed received
 upon confirmation of transmission by the sender's facsimile machine. Notices
 given by a Holder shall be addressed to the Company at 406 West Main Street,
 Abingdon, Virginia, 24212, Attention: Chief Financial Officer, fax: (276)
 628-3116. Notices given by the Company to the Holder shall be addressed to the
 Holder at the address for notice specified in the Internal Restructuring
 Agreement.

            (c) EXERCISE OF RIGHTS. No delay on the part of the Holder in the
exercise of any power or right under this Note shall operate as a waiver
thereof.

            (d) WAIVERS. The Company waives presentment, demand for payment,
notice of dishonor, protest, notice of protest, and all other notices of any
kind with respect to this Note. The right to plead any and all statutes of
limitations as a defense to any demands hereunder is hereby waived to the
fullest extent permitted by law.

            (e) SEVERABILITY. If any term of this Note is, to any extent,
invalid or unenforceable, the remainder of this Note shall not be affected
thereby, and this Note shall be construed as if such invalid or unenforceable
provision had never been contained herein.

            (f) LOSS OR THEFT OF NOTE. Upon receipt of evidence satisfactory to
the Company of the loss, theft, mutilation or destruction of this Note, and, if
requested by the Company, a reasonable indemnification by the Holder, the
Company shall make and deliver without expense to the Holder a new Note, of like
tenor and issue, in lieu of the lost, stolen, destroyed or mutilated Note.

            (g) AMENDMENT. The Notes may not be amended except by an instrument
in writing referring to this Note signed by the Company and the Holder.
