FIRST SUPPLEMENTAL
INDENTURE






SUPPLEMENTAL
INDENTURE (this “Supplemental
Indenture”), dated as of December 3, 2009, among Powell Mountain
Energy, LLC (the “Material
Subsidiary”), a subsidiary of International Coal Group, Inc., a Delaware
corporation (the “Company”), the other
Guarantors (as defined in the Indenture referred to herein) and The Bank of New
York Mellon Trust  Company, N.A., as trustee under the Indenture
referred to below (the “Trustee”).






W
I T N E S S E T H




WHEREAS,
the Company has heretofore executed and delivered to the Trustee an indenture
(the “Indenture”), dated
as of July 31, 2007 providing for the issuance of 9.00% Convertible Senior
Notes due 2012 (the “Notes”);






WHEREAS,
Section 4.09 of the Indenture provides that new Material Subsidiaries shall
execute and deliver to the Trustee a supplemental indenture pursuant to which
the Material Subsidiary shall unconditionally guarantee all of the Company’s
payment obligations under the Notes and the Indenture on the terms and
conditions set forth herein (the “Note Guarantee”);
and






WHEREAS,
pursuant to Section 9.01 of the Indenture, the Trustee is authorized to
execute and deliver this Supplemental Indenture.






NOW,
THEREFORE, in consideration of the foregoing and for other good and valuable
consideration, the receipt of which is hereby acknowledged, the Material
Subsidiary and the Trustee mutually covenant and agree for the equal and ratable
benefit of the Holders of the Notes as follows:






1.
CAPITALIZED TERMS. Capitalized terms used herein without definition shall have
the meanings assigned to them in the Indenture.






2.
AGREEMENT TO GUARANTEE. The Material Subsidiary hereby agrees to provide an
unconditional Guarantee on the terms and subject to the conditions set forth in
the Note Guarantee and in the Indenture including but not limited to Article XI
thereof.






3.
NO RECOURSE AGAINST OTHERS. No past, present or future director, manager,
officer, employee, incorporator, member, stockholder or agent of the Material
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Material Subsidiary under the Notes, any Note Guarantees, the Indenture
or this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the SEC that such a waiver is against public policy.












4.
NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN
AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO
APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.






5.
COUNTERPARTS. The parties may sign any number of copies of this Supplemental
Indenture. Each signed copy shall be an original, but all of them together
represent the same agreement.






6.
EFFECT OF HEADINGS. The Section headings herein are for convenience only and
shall not affect the construction hereof.






7.
THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for
or in respect of the validity or sufficiency of this Supplemental Indenture or
for or in respect of the recitals contained herein, all of which recitals are
made solely by the Material Subsidiary and the Company.






IN
WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to
be duly executed and attested, all as of the date first above
written.
