                            ROCKY MOUNTAIN AGREEMENTS
                    ASSIGNMENT AND ASSUMPTION AGREEMENT (P1)

        This ROCKY MOUNTAIN AGREEMENTS ASSIGNMENT AND ASSUMPTION AGREEMENT (P1),
dated as of December 30, 1996 (as amended, supplemented or otherwise modified
from time to time in accordance with the provisions hereof, this "Rocky Mountain
Agreements Assignment"), between OGLETHORPE POWER CORPORATION (AN ELECTRIC
MEMBERSHIP GENERATION & TRANSMISSION CORPORATION), an electric membership
corporation organized under the laws of the State of Georgia (together with its
successors and permitted assigns, the "Assignor"), and SUNTRUST BANK, ATLANTA, a
state banking corporation, not in its individual capacity but solely as
Co-Trustee under the Trust Agreement (P1), dated as of December 30, 1996, with
the Owner Trustee and the Owner Participant (together with its successors and
permitted assigns, the "Assignee").

        WHEREAS, the Assignor and Georgia Power Company, a corporation organized
under the laws of the State of Georgia (together with its successors and
permitted assigns, Georgia Power") own the Rocky Mountain Site as tenants in
common under Georgia law;

        WHEREAS, by the Rocky Mountain Agreements, the Assignor and Georgia
Power established their respective rights and obligations as tenants in common
of the Rocky Mountain Site and of all improvements thereafter to be constructed,
and all personal property thereafter to be situated, on the Rocky Mountain Site.
Such improvements and personal property owned by the Assignor and Georgia Power
as tenants in common under Georgia law include the Facility;

        WHEREAS, as tenants in common of such real and personal property, the
Assignor and Georgia Power hold a 74.61% and 25.39% undivided interest,
respectively, in such real and personal property, including the right to

rights of the other to nonexclusive possession and the terms and conditions of
the Rocky Mountain Agreements;

        WHEREAS, by this Rocky Mountain Agreements Assignment, the Assignor will
assign the Assigned Rocky Mountain Interests to the Assignee for a term which is
coterminous with the term of the Head Lease.

        NOW, THEREFORE, in consideration of the foregoing premises, the mutual
agreements herein contained, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

SECTION 1. DEFINITIONS.

        Capitalized terms used in this Rocky Mountain Agreements Assignment,
including the recitals, and not otherwise defined herein shall have the
respective meanings specified in Appendix A to the Participation Agreement (P1),
dated as of December 30, 1996, among the


Assignor, the Assignee, Fleet National Bank, not in its individual capacity but
solely as Owner Trustee under the Trust Agreement (the "Owner Trustee"), Rocky
Mountain Leasing Corporation, a Delaware corporation ("RMLC"), Philip Morris
Capital Corporation, a Delaware corporation (the "Owner Participant") and
Utrecht-America Finance Co. The general provisions of Appendix A shall apply to
terms used in this Rocky Mountain Agreements Assignment and specifically defined
herein.

SECTION 2. ASSIGNMENT OF ASSIGNED ROCKY MOUNTAIN INTERESTS TO ASSIGNEE.

        The Assignor hereby assigns the Assigned Rocky Mountain Interests to the
Assignee. The assignment effected by this Section 2 shall become effective on
and as of the Closing Date and shall terminate on the expiration or earlier
termination of the Head Lease Term.

SECTION 3. ASSUMPTION BY ASSIGNEE.

        The Assignee hereby assumes, and agrees to perform, any and all
liabilities and obligations of the Assignor incurred with respect to the
Assigned Rocky Mountain Interests, recourse with respect to such obligations to
be limited to the Assignee's interest in the Undivided Interest with respect to
any obligations based on circumstances occurring prior to the termination of the
Facility Lease. This assumption shall terminate (except with respect to any
liability or obligation which has accrued prior to such termination) on the
expiration or earlier termination of the Head Lease Term. Simultaneously
herewith, RMLC is executing and delivering the Rocky Mountain Agreements
Re-assignment pursuant to which RMLC will assume and agree to perform any and
all liabilities and obligations of the Assignee incurred with respect to the
Assigned Rocky Mountain Interests resulting from the Assignee's assumption of
the liabilities and the obligations of the Assignor under this Section 3. The
Assignor acknowledges such assumption and agreement by RMLC and agrees that
during the effective period of the assumption and agreement by RMLC pursuant to
the Rocky Mountain Agreements Re-assignment, (i) by entering into the Facility
Lease and the Rocky Mountain Agreements Re-assignment, the Assignee shall be
deemed to have complied with all duties or obligations with respect to the
liabilities or obligations assumed or agreed to be performed by the Assignee in
respect of the Assigned Rocky Mountain Interests under this Section 3, (ii) any
default by RMLC in the performance of the liabilities and obligations assumed
and agreed to be performed by RMLC in accordance with the Rocky Mountain
Agreements Re-assignment, shall not be (or be deemed to be) a default by the
Assignee in the performance of the liabilities and obligations assumed and
agreed to be performed by the Assignee under this Section 3 and (iii) the
consequences of any action or inaction on the part of RMLC (other than full and
complete performance) in the performance of the liabilities and obligations
assumed and agreed to be performed by RMLC in accordance with the Rocky Mountain
Agreements Re-assignment, or otherwise with respect to the Assigned Rocky
Mountain Interests, shall not be attributed to the Assignee (including, without
limitation, any Liens, incurred, assumed or suffered to exist by RMLC on the
Assigned Rocky Mountain Interests).


                                        2


SECTION 4. NONTERMINABILITY.

        Subject to Section 2 hereof notwithstanding anything herein or otherwise
to the contrary, neither the rights of the Assignee nor the obligations of the
Assignor under this Rocky Mountain Agreements Assignment shall be terminated,
extinguished, diminished, lost or otherwise impaired by any circumstances of any
character or for any reason whatsoever, whether or not the same involves the
loss of all or any part of the interest assigned by this Rocky Mountain
Agreements Assignment, including, without limitation, any of the following
circumstances or reasons: (a) any damage to or loss or destruction of all or any
part of the Facility for any reason whatsoever and of whatever duration, (b) the
condemnation, requisition (by eminent domain or otherwise), seizure or other
taking of title or use of all or any part of the Facility by any Governmental
Entity or otherwise, (c) any prohibition, limitation or restriction on the use

use by any Person, or any foreclosure or deed in lieu of foreclosure of the
Oglethorpe Mortgage, or any termination of the interests created by this Rocky
Mountain Agreements Assignment as a result thereof by operation of law or
contract, or any eviction by paramount title or otherwise, (d) any inadequacy,
incorrectness or failure of the description of the Facility or the Assigned
Rocky Mountain Interests or any part thereof or any rights or property in which
an interest is intended to be granted or conveyed by this Rocky Mountain
Agreements Assignment, (e) the insolvency, bankruptcy, reorganization or similar
proceedings by or against the Assignor, the Assignee or any other Person, (f)
the failure by the Assignee to comply with any provision hereof or of any other
Operative Document or (g) any other reason whatsoever, whether similar or
dissimilar to any of the foregoing.

SECTION 5. TERMINATION OPTION.

        After the expiration or earlier termination of the Facility Lease Term,
the Assignee may terminate this Rocky Mountain Agreements Assignment upon thirty
days prior written notice to the Assignor; provided, however, that the Assignee
shall simultaneously terminate the Head Lease pursuant to Section 3.5 thereof.

SECTION 6. SECURITY FOR ASSIGNEE'S OBLIGATION TO THE LENDER.

        In the order to secure the Secured Indebtedness, the Assignee will by
the Loan Agreement grant and assign a Lien, and by the Deed to Secure Debt
convey security title, to the Lender in, to and under this Rocky Mountain
Agreements Assignment and the Facility Lessor's Rocky Mountain Interest (other
than Excepted Payments and Excepted Rights). The Assignor hereby consents to
such assignment and the creation of such Lien and security title and
acknowledges receipt of copies of the Loan Agreement and the Deed to Secure
Debt, it being understood that such consent shall not affect any requirement or
the absence of any requirement for any consent under any other circumstances.
Unless and until the Assignor shall have received written notice from the Lender
that the Lien of the Loan Agreement and


                                        3


the security title of the Deed to Secure Debt have been fully terminated, the
Lender shall have the right to exercise the rights of the Assignee under this

each case to the exceptions set forth in the Loan Agreement or the Deed to
Secure Debt.
