               Each

Advances pursuant to Section 2.12 and utilize the resulting increase in the

terms hereof.  In no event shall any Borrower be entitled to request
or receive any Borrowing that would cause the aggregate Outstanding Credits (x)
of all Borrowers to exceed the Commitments or (y) of such Borrower to exceed the
Borrower Sublimit of such Borrower.

     

    SECTION
2.02. Making
the Ratable Advances.

     

    (a) Each
Borrowing (other than with respect to Swingline Advances) shall be in an amount
not less than $10,000,000 (or, if less, the lesser of the Available Commitments
and the Borrower Sublimit of the relevant Borrower at such time) or an integral
multiple of $1,000,000 in excess thereof and shall consist of Advances (other
than Swingline Advances) of the same Type made on the same day by the Lenders
ratably according to their respective Commitment Percentages.  Each
Borrowing (other than with respect to Swingline Advances) shall be made on
notice, given not later than 11:00 A.M. on the third Business Day prior to the
date of the proposed Borrowing in the case of a Borrowing consisting of
Eurodollar Rate Advances, or not later than 9:30 A.M. on the date of the
proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances,
by the applicable Borrower to the Administrative Agent, which shall give to each
Lender prompt notice thereof by telecopier or telex.  Each such notice
of a Borrowing (a “Notice of
Borrowing”) shall be by telephone, confirmed immediately in writing, or
telecopier or telex in substantially the form of Exhibit A hereto, specifying
therein the requested (i) Borrowing Date for such Borrowing, (ii) Type of
Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing,
and (iv) in the case of a Borrowing consisting of Eurodollar Rate Advances, the
initial Interest Period for each such Advance.  Each Lender shall,
before 12:00 noon on the applicable Borrowing Date, make available for the
account of its Applicable Lending Office to the Administrative Agent at the
Agent’s Account, in same day funds, such Lender’s ratable portion of the
Borrowing to be made on such Borrowing Date.  After the Administrative
Agent’s receipt of such funds and upon fulfillment of the applicable conditions
set forth in Article III, the Administrative Agent will promptly make such funds
available to the applicable Borrower in such manner as the applicable Borrower
shall have specified in the applicable Notice of Borrowing and as shall be
reasonably acceptable to the Administrative Agent.

     

    (b) Anything
in subsection (a) above to the contrary notwithstanding, (i) no Borrower may
select Eurodollar Rate Advances for any Borrowing if the aggregate amount of
such Borrowing is less than $10,000,000 or if the obligation of the Lenders to
make Eurodollar Rate Advances shall then be suspended pursuant to Section
2.10(c), 2.10(f) or 2.14, and (ii) there shall be not more than 20 Borrowings at
any one time outstanding.

     

    (c) Each
Notice of Borrowing shall be irrevocable and binding on the applicable
Borrower.  In the case of any Borrowing that the related Notice of
Borrowing specifies is to comprise Eurodollar Rate Advances, the applicable
Borrower shall indemnify each Lender against any loss, cost or expense incurred
by such Lender as a result of any failure to fulfill on or before the date
specified in such Notice of Borrowing for such Borrowing the applicable
conditions set forth in Article III, including, without limitation, any loss
(including loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Lender to fund the Advance to be made by such Lender as part of such Borrowing
when such Advance, as a result of such failure, is not made on such
date.

     

    (d) Unless
the Administrative Agent shall have received notice by telegram, telex or
telecopier from a Lender prior to any Borrowing Date or, in the case of a Base
Rate Advance, prior to the time of Borrowing, that such Lender will not make
available to the Administrative Agent such Lender’s Advance as part of the
Borrowing to be made on such Borrowing Date, the Administrative Agent may assume
that such Lender has made such portion available to the Administrative Agent on
such Borrowing Date in accordance with subsection (a) of this Section 2.02, and
the Administrative Agent may (but it shall not be required to), in reliance upon
such assumption, make available to the applicable Borrower on such date a
corresponding amount.  If and to the extent that such Lender shall not
have so made such Advance available to the Administrative Agent, such Lender and
the applicable Borrower severally agree to repay to the Administrative Agent
forthwith on demand such corresponding amount, together with interest thereon,
for each day from the date such amount is made available to such Borrower until
the date such amount is repaid to the Administrative Agent, at (i) in the case
of such Borrower, the interest rate applicable at the time to Advances
comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds
Rate.  If such Lender shall repay to the Administrative Agent such
corresponding amount, such amount so repaid shall constitute such Lender’s
Advance as part of such Borrowing for purposes of this Agreement.

     

    (e) The
failure of any Lender to make the Advance to be made by it as part of any
Borrowing shall not relieve any other Lender of its obligation, if any,
hereunder to make its Advance on the date of such Borrowing, but no Lender shall
be responsible for the failure of any other Lender to make the Advance to be
made by such other Lender on the date of any Borrowing.

     

    SECTION

aggregate principal amount of outstanding Swingline Advances exceeding
$65,000,000 or (ii) the Outstanding Credits exceeding the Commitments; provided that the Swingline
Bank shall not be required to make a Swingline Advance to refinance an
outstanding Swingline Advance.  Within the limits as hereinabove and
hereinafter provided, AEP may request Swingline Advances hereunder, and repay or
prepay Swingline Advances pursuant to Section 2.12 and utilize the resulting
increase in the Available Commitments for further Swingline Advances in
accordance with the terms hereof.  Each Swingline Advance shall be a
Base Rate Advance and shall be in an amount that is an integral multiple of
$500,000 and not less than $1,000,000.

     

    (b)           To
request a Swingline Advance, AEP shall notify the Swingline Bank of such request

Advance.  Each such notice shall be irrevocable and shall specify the
requested date (which shall be a Business Day) and amount of the requested
Swingline Advance.  The Swingline Bank shall make each Swingline
Advance available to AEP by means of a credit to the general deposit account of
AEP with the Swingline Bank by 3:00 p.m., New York City time, on the requested
date of such Swingline Advance.

     

    (c)           The
Swingline Bank may by written notice given to the Administrative Agent not later
than 12:00 p.m., New York City time, on any Business Day require the Lenders to
acquire participations on such Business Day in all or a portion of the Swingline
Advances outstanding.  Such notice shall specify the aggregate amount
of Swingline Advances in which the Lenders will participate.  Promptly
upon receipt of such notice, the Administrative Agent will give notice thereof
to each Lender, specifying in such notice such Lender's Commitment Percentage of
such Swingline Advance or Advances.  Each Lender hereby absolutely and
unconditionally agrees, upon receipt of notice as provided above, to pay to the
Administrative Agent, for the account of the Swingline Bank, such Lender’s
Commitment Percentage of such Swingline Advance or Advances.  Each
Lender acknowledges and agrees that its obligation to acquire participations in
Swingline Advances pursuant to this subsection is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or reduction or termination of the Commitments, and
that each such payment shall be made without any offset, abatement, withholding
or reduction whatsoever.  Each Lender shall comply with its obligation
under this subsection by wire transfer of immediately available funds, in the
same manner as provided in Section 2.02(a) with respect to Advances made by such
Lender (and Section 2.02 shall apply, mutatis mutandis, to the
payment obligations of the Lenders), and the Administrative Agent shall promptly
pay to the Swingline Bank the amounts so received by it from the
Lenders.  The Administrative Agent shall notify AEP of any
participations in any Swingline Advance acquired pursuant to this subsection,
and thereafter payments in respect of such Swingline Advance shall be made to
the Administrative Agent and not to the Swingline Bank.  Any amounts
received by the Swingline Bank from AEP (or other party on behalf of AEP) in
respect of a Swingline Advance after receipt by the Swingline Bank of the
proceeds of a sale of participations therein shall be promptly remitted to the
Administrative Agent; any such amounts received by the Administrative Agent
shall be promptly remitted by the Administrative Agent to the Lenders that shall
have made their payments pursuant to this subsection (to the extent of each
applicable Lender’s participation) and to the Swingline Bank to the extent of
its retained interest; provided that any such payment so remitted shall be
repaid to the Swingline Bank or to the Administrative Agent, as applicable, if
and to the extent such payment is required to be refunded to AEP for any
reason.  The purchase of participations in a Swingline Advance
pursuant to this subsection shall not relieve AEP of any default in the payment
thereof.

     

    SECTION
2.04. Letters
of Credit.

     

    (a) Each of
JPMCB and RBS has agreed to act as an LC Issuing Bank and, in such capacity,
each has agreed to issue Letters of Credit having an aggregate face amount not
greater than $325,000,000 for each such LC Issuing Bank.  AEP may also
from time to time appoint one or more other Lenders (with the consent of any
such Lender, which consent may be withheld in the sole discretion of each
Lender) to act, either directly or through an Affiliate of such Lender, as an LC
Issuing Bank hereunder.  Any such appointment and the terms thereof
shall be evidenced in a separate written agreement executed by AEP and the
relevant LC Issuing Bank, a copy of which agreement shall be delivered by AEP to
the Administrative Agent.  The Administrative Agent shall give prompt
notice of any such appointment to the other Lenders.  Upon such
appointment, if and for so long as such Lender shall have any obligation to
issue any Letters of Credit hereunder or any Letter of Credit issued by such
Lender shall remain outstanding, such Lender shall be deemed to be, and shall
have all the rights and obligations of, an “LC Issuing Bank” under this
Agreement.

     

    (b) Subject
to the terms and conditions hereof, each Letter of Credit shall be issued (or
the stated maturity thereof extended or terms thereof modified or amended) on
not less than two Business Days’ prior notice thereof by delivery of (i) a
Request for Issuance to the Administrative Agent (which shall promptly
distribute copies thereof to the Lenders) and the relevant LC Issuing Bank and
(ii) the relevant LC Issuing Bank’s standard form of Letter of Credit
application to such LC Issuing Bank for the account of the applicable Borrower
or any of its Subsidiaries; provided that such Borrower shall be the account
party for the purposes of this Agreement and shall have the reimbursement
obligations with respect thereto.  Each Letter of Credit shall be
issued in a form acceptable to the LC Issuing Bank.  Each Request for
Issuance shall specify (i) the identity of the relevant LC Issuing Bank, (ii)
the date (which shall be a Business Day) of issuance of such Letter of Credit
(or the date of effectiveness of such extension, modification or amendment) and
the stated expiry date thereof (which shall be not more than one year after the
date of issuance, provided, that if the expiry date
of such Letter of Credit is later than the Termination Date, the applicable
Borrower will (x) five Business Days prior to the Termination Date if such
Borrower’s Applicable Rating Level is 5 or above and (y) 15 days prior to the
Termination Date if such Borrower’s Applicable Rating Level is 6, deposit in an
account designated with the Administrative Agent (the “LC Collateral
Account”), in the name of the Administrative Agent and for the benefit of
the Lenders and LC Issuing Banks, in same day funds, an amount equal to 103% of
the aggregate undrawn stated amount of such Letter of Credit), (iii) the
proposed stated amount of such Letter of Credit (which amount shall not (A) be
less than $100,000 and (B) be subject to any automatic increase provisions),
(iv) the name and address of the beneficiary of such Letter of Credit and (v) a
statement of drawing conditions applicable to such Letter of
Credit.  Notwithstanding any Borrower’s deposit of funds into the LC
Collateral Account pursuant to Section 2.04(b)(ii), such Borrower’s
reimbursement obligations with respect to such Letter of Credit shall remain in
effect until such Letter of Credit is no longer outstanding.  Each
Request for Issuance shall be irrevocable unless modified or rescinded by the
applicable Borrower not less than two Business Days prior to the proposed date
of issuance (or effectiveness) specified therein.  On the proposed
date of issuance (or effectiveness) specified in such Request for Issuance, and
upon fulfillment of the applicable conditions precedent and the other
requirements set forth herein, the applicable LC Issuing Bank shall issue (or
extend, amend or modify) such Letter of Credit and provide notice and a copy
thereof to the Administrative Agent, which shall promptly furnish copies thereof
to the Lenders; provided that the LC Issuing Bank shall not issue or amend any
Letter of Credit if such LC Issuing Bank has received notice from the
Administrative Agent that the applicable conditions precedent have not been
satisfied.

     

    (c) No Letter
of Credit shall be requested or issued hereunder if, after the issuance thereof,
the Outstanding Credits would exceed the aggregate Commitments.

     

    (d) Each
Borrower hereby agrees to pay to the Administrative Agent for the account of
each LC Issuing Bank and, if they shall have purchased participations in the
reimbursement obligations of any Borrower pursuant to subsection (e) below, the
participating Lenders, on demand made by such LC Issuing Bank to such Borrower,
on and after each date on which such LC Issuing Bank shall pay any amount under
any Letter of Credit issued by such LC Issuing Bank, a sum equal to the amount
so paid plus interest on such amount from the date so paid by such LC Issuing
Bank until repayment to such LC Issuing Bank in full at a fluctuating interest
rate per annum equal to the interest rate applicable to Base Rate Advances plus,
if any amount paid by such LC Issuing Bank under a Letter of Credit is not
reimbursed by such Borrower on the next succeeding Business Day after such
demand, 2%.

     

    (e) If any LC
Issuing Bank shall not have been reimbursed in full for any payment made by such
LC Issuing Bank under a Letter of Credit issued by such LC Issuing Bank on the
date of such payment, such LC Issuing Bank shall give the Administrative Agent
and each Lender prompt notice thereof (an “LC Payment
Notice”) no later than 12:00 noon on the Business Day immediately
succeeding the date of such payment by such LC Issuing Bank.  Each
Lender severally agrees to purchase a participation in the reimbursement
obligation of the applicable Borrower to such LC Issuing Bank by paying to the
Administrative Agent for the account of such LC Issuing Bank an amount equal to
such Lender’s Commitment Percentage of such unreimbursed amount paid by such LC
Issuing Bank, plus interest on such amount at a rate per annum equal to the
Federal Funds Rate from the date of the payment by such LC Issuing Bank to the
date of payment to such LC Issuing Bank by such Lender.  Each such
payment by a Lender shall be made not later than 3:00 P.M. on the later to occur
of (i) the Business Day immediately following the date of such payment by such
LC Issuing Bank and (ii) the Business Day on which such Lender shall have
received an LC Payment Notice from such LC Issuing Bank.  Each
Lender’s obligation to make each such payment to the Administrative Agent for
the account of such LC Issuing Bank shall be several and shall not be affected
by the occurrence or continuance of a Default or the failure of any other Lender
to make any payment under this Section 2.04(e).  Each Lender further
agrees that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

     

    (f) The
failure of any Lender to make any payment to the Administrative Agent for the
account of any LC Issuing Bank in accordance with subsection (e) above shall not
relieve any other Lender of its obligation to make payment, but no Lender shall
be responsible for the failure of any other Lender.  If any Lender (a
“non-performing
Lender”) shall fail to make any payment to the Administrative Agent for
the account of any LC Issuing Bank in accordance with subsection (e) above,
then, for so long as such failure shall continue, such LC Issuing Bank shall be
deemed, for purposes of Sections 6.01 and 8.01 hereof, to be a Lender owed a
Borrowing in an amount equal to the outstanding principal amount due and payable
by such non-performing Lender to the Administrative Agent for the account of
such LC Issuing Bank pursuant to subsection (e) above.  Any
non-performing Lender and the applicable Borrower (without waiving any claim
against such Lender for such Lender’s failure to purchase a participation in the
reimbursement obligations of such Borrower under subsection (e) above) severally
agree to pay to the Administrative Agent for the account of such LC Issuing Bank
forthwith on demand such amount, together with interest thereon for each day
from the date such Lender would have purchased its participation had it complied
with the requirements of subsection (e) above until the date such amount is paid
to the Administrative Agent at (i) in the case of such Borrower, the interest
rate applicable at the time to Base Rate Advances plus, if any amount paid by
such LC Issuing Bank under a Letter of Credit is not reimbursed by such Borrower
in accordance with Section 2.04(d), and (ii) in the case of such Lender, the
Federal Funds Rate.

     

    (g) The
payment obligations of each Lender under Section 2.04(e) and of the Borrowers
under this Agreement in respect of any payment under any Letter of Credit shall
be unconditional and irrevocable, and shall be paid strictly in accordance with
the terms of this Agreement under all circumstances, including, without
limitation, the following circumstances:

     

    (i) any lack
of validity or enforceability of this Agreement or any other agreement or
instrument relating thereto or to such Letter of Credit;

     

    (ii) any
amendment or waiver of, or any consent to departure from, the terms of this
Agreement or such Letter of Credit;

     

    (iii) the
existence of any claim, set-off, defense or other right that any Borrower may
have at any time against any beneficiary, or any transferee, of such Letter of
Credit (or any Persons for whom any such beneficiary or any such transferee may
be acting), any LC Issuing Bank, or any other Person, whether in connection with
this Agreement, the transactions contemplated hereby, thereby or by such Letter
of Credit, or any unrelated transaction;

     

    (iv) any
statement or any other document presented under such Letter of Credit proving to
be forged, fraudulent, invalid or insufficient in any respect or any statement
therein being untrue or inaccurate in any respect;

     

    (v) payment
in good faith by any LC Issuing Bank under the Letter of Credit issued by such
LC Issuing Bank against presentation of a draft or certificate that does not
comply with the terms of such Letter of Credit;

     

    (vi) the use
that may be made of any Letter of Credit by, or any act or omission of, the
beneficiary of any Letter of Credit (or any Person for which the beneficiary may
be acting); or

     

    (vii) any other
circumstance or happening whatsoever, whether or not similar to any of the
foregoing.

     

    Without
limiting the foregoing, the obligations with respect to Letters of Credit of
each Lender shall be reinstated, to the extent that funds deposited in the Cash
Collateral Account by any Borrower pursuant to Section 2.04(b), the application
thereof or reimbursement in respect thereof, is required to be returned to such
Borrower by the LC Issuing Bank after the Termination Date.

    


    (h) Without
limiting any other provision of this Section 2.04, for purposes of this Section
2.04 any LC Issuing Bank may rely upon any oral, telephonic, telegraphic,
facsimile, electronic, written or other communication believed in good faith to
have been authorized by the applicable Borrower, whether or not given or signed
by an authorized Person of such Borrower.

     

    (i) Each
Borrower assumes all risks of the acts and omissions of any beneficiary or
transferee of any Letter of Credit.  Neither any LC Issuing Bank, the
Lenders nor any of their respective officers, directors, employees, agents or
Affiliates shall be liable or responsible for  (i) the use that may be
made of such Letter of Credit or any acts or omissions of any beneficiary or
transferee thereof in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; (iii) payment by any LC Issuing Bank against presentation of documents
that do not comply with the terms of such Letter of Credit, including failure of
any documents to bear any reference or adequate reference to such Letter of
Credit; or (iv) any other circumstances whatsoever in making or failing to make
payment under such Letter of Credit, except that the applicable Borrower and
each Lender shall have the right to bring suit against each LC Issuing Bank, and
each LC Issuing Bank shall be liable to such Borrower and any Lender, to the
extent of any direct, as opposed to consequential, damages suffered by such
Borrower or such Lender that such Borrower or such Lender proves were caused by
such LC Issuing Bank’s willful misconduct or gross negligence, including, in the
case of such Borrower, such LC Issuing Bank’s willful failure to make timely
payment under such Letter of Credit following the presentation to it by the
beneficiary thereof of a draft and accompanying certificate(s) that strictly
comply with the terms and conditions of such Letter of Credit.  In
furtherance and not in limitation of the foregoing, each LC Issuing Bank may
accept sight drafts and accompanying certificates presented under the Letter of
Credit issued by such LC Issuing Bank that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary, and payment against such documents shall not
constitute willful misconduct or gross negligence by such LC Issuing Bank.
Notwithstanding the foregoing, no Lender shall be obligated to indemnify any
Borrower for damages caused by any LC Issuing Bank’s willful misconduct or gross
negligence.

     

    SECTION
2.05. Fees.

     

    (a) AEP
agrees to pay to the Administrative Agent for the account of each Lender a
commitment fee on such Lender’s Commitment Percentage of the Available
Commitments from the date hereof in the case of each Initial Lender and from the
effective date specified in the Assignment and Acceptance pursuant to which it
became a Lender in the case of each other Lender until the Termination Date,
payable quarterly in arrears on the last day of each March, June, September and
December, commencing June 30, 2008, and ending on the Termination Date; provided that, solely for
purposes of calculating the Outstanding Credits of such Lender in order to
determine such Lender’s Available Commitment under this Section 2.05(a), the
aggregate principal amount of Swingline Advances then outstanding (other than
Swingline Advances in which such Lender has a participation) shall be deemed to
be zero.  The commitment fee for any period will be equal to the
Commitment Fee Rate in effect from time to time during such period, times the
Commitments minus the aggregate principal amount of Advances outstanding during
such period.

     

    (b) AEP shall
pay to the Administrative Agent for the account of the Administrative Agent such
fees as may from time to time be agreed between the AEP and the Administrative
Agent.

     

    (c) Each
Borrower shall pay to the Administrative Agent for the account of each Lender a
fee (the “LC Fee”)
on the average daily aggregate principal amount of each such Lender’s Commitment
Percentage of the LC Outstandings with respect to such Borrower from the date
hereof until the later to occur of the Termination Date and the date on which no
Letters of Credit are outstanding, payable on the last day of each March, June,
September and December (commencing on June 30, 2008), and on such later date, at
a rate equal at all times to the Applicable Margin in effect from time to time
for Eurodollar Rate Advances.

     

    (d) Each
Borrower shall pay to each LC Issuing Bank such fees for the issuance and
maintenance of Letters of Credit issued by such LC Issuing Bank and for drawings
thereunder as may be separately agreed between such Borrower and such LC Issuing
Bank.

     

    SECTION
2.06. Termination
or Reduction of the Commitments.

     

    (a) AEP shall
have the right, upon at least three Business Days’ notice to the Administrative
Agent, to terminate in whole or reduce ratably in part the Available
Commitments, provided
that (i) each partial reduction shall be in the aggregate amount of $5,000,000
or an integral multiple of $1,000,000 in excess thereof and (ii) no such
termination or reduction shall be made that would reduce the aggregate
Commitments to an amount less than the Outstanding Credits on the date of such
termination or reduction.

     

    (b) The
Commitments shall automatically terminate on the Termination Date.

     

    (c) Once
terminated, a Commitment, or any portion thereof, may not be
reinstated.

     

    SECTION
2.07. Repayment
of Advances.

     

    (a) Each
Borrower shall repay to the Administrative Agent for the account of each Lender
on the Termination Date with respect to such Lender the aggregate principal
amount of the Advances (other than Swingline Advances) made by such Lender to
such Borrower then outstanding.  AEP will repay to the Swingline Bank
the then unpaid principal amount of each Swingline Advance on the earliest of
the Termination Date, the fifth Business Day after such Swingline Advance is
made and any date on which a Borrowing (other than with respect to a Swingline
Advance) is made.

     

    (b) If at any
time (i) the aggregate principal amount of Advances outstanding exceeds the
aggregate Commitments, the Borrowers shall pay or prepay so much of the
Borrowings as shall be necessary in order that the principal amount of Advances
outstanding will not exceed the Commitments.

     

    SECTION
2.08. Evidence
of Indebtedness.

     

    (a) Each
Lender shall maintain in accordance with its usual practice an account or
accounts evidencing the indebtedness to such Lender resulting from each Advance
made by such Lender from time to time, including the amounts of principal and
interest payable and paid to such Lender from time to time under this
Agreement.

     

    (b) The
Administrative Agent shall maintain accounts in which it will record (i) the
amount and Borrower of each Advance made hereunder, the Type of each Advance
made and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from each
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder from each Borrower and each Lender’s share
thereof.

     

    (c) The
entries made in the accounts maintained pursuant to subsections (a) and (b) of
this Section 2.08 shall, to the extent permitted by Applicable Law, be prima
facie evidence of the existence and amounts of the obligations therein recorded;
provided, however, that the failure of
any Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligations of any Borrower to repay
the Advances and interest thereon in accordance with their terms.

     

    (d) Any
Lender may request that any Advances made by it be evidenced by one or more
promissory notes.  In such event, each Borrower shall prepare, execute
and deliver to such Lender one or more promissory notes payable to the order of
such Lender (or, if requested by such Lender, to such Lender and its assignees)
and in a form approved by the Administrative Agent.  Thereafter, the
Advances evidenced by such promissory notes and interest thereon shall at all
times (including after assignment pursuant to Section 8.07) be represented by
one or more promissory notes in such form payable to the order of the payee
named therein.

     

    SECTION
2.09. Interest
on Advances.

     

    Each
Borrower shall pay interest on the unpaid principal amount of each Advance made
to such Borrower from the date of such Advance until such principal amount shall
be paid in full, at the following rates per annum:

     

    (a) Base Rate
Advances.  During such periods as such Advance is a Base Rate
Advance or a Swingline Advance, a rate per annum equal at all times to the sum
of (x) the Base Rate plus (y) the Applicable Margin for Base Rate Advances in
effect from time to time, payable in arrears quarterly on the last day of each
March, June, September and December during such periods and on the date such
Base Rate Advance shall be Converted or paid in full.  

     

    (b) Eurodollar Rate
Advances.  During such periods as such Advance is a Eurodollar
Rate Advance, a rate per annum equal at all times during each Interest Period
for such Advance to the sum of (x) the Eurodollar Rate for such Interest Period
for such Advance plus (y) the Applicable Margin for Eurodollar Rate Advances in
effect from time to time, payable in arrears on the last day of such Interest
Period and, if such Interest Period has a duration of more than three months, on
each day that occurs during such Interest Period every three months from the
first day of such Interest Period and on the date such Eurodollar Rate Advance
shall be Converted or paid in full.  

     

    (c) Additional
Interest on Eurodollar Rate Advances.  Each Borrower shall pay
to each Lender, so long as such Lender shall be required under regulations of
the Board of Governors of the Federal Reserve System to maintain reserves with
respect to liabilities or assets consisting of or including Eurocurrency
Liabilities, additional interest on the unpaid principal amount of each
Eurodollar Rate Advance of such Lender made to such Borrower, from the date of
such Advance until such principal amount is paid in full, at an interest rate
per annum equal at all
times to the remainder obtained by subtracting (i) the Eurodollar Rate for the
Interest Period for such Advance from (ii) the rate obtained by dividing such
Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate
Reserve Percentage of such Lender for such Interest Period, payable on each date
on which interest is payable on such Advance.  Such additional
interest shall be determined by such Lender and notified to such Borrower
through the Administrative Agent.

     

    SECTION
2.10. Interest
Rate Determination.

     

    (a) To the
extent required hereunder, each Reference Bank agrees to furnish to the
Administrative Agent timely information for the purpose of determining each
Eurodollar Rate.  If fewer than two Reference Banks furnish such
timely information to the Administrative Agent for the purpose of determining
any such rate, the Administrative Agent shall determine such interest rate on
the basis of timely information furnished by the remaining Reference
Bank.

     

    (b) The
Administrative Agent shall give prompt notice to the applicable Borrower and the
Lenders of the applicable interest rate determined by the Administrative Agent
for purposes of Section 2.09(a) or (b), and, if applicable, the applicable rate,
if any, furnished by each Reference Bank for the purpose of determining the
applicable interest rate under Section 2.09(b).

     

    (c) If, with
respect to any Eurodollar Rate Advances, (i) the Required Lenders notify the
Administrative Agent that the Eurodollar Rate for any Interest Period for such
Advances will not adequately reflect the cost to such Required Lenders of
making, funding or maintaining their respective Eurodollar Rate Advances for
such Interest Period, or (ii) the Reference Banks notify the Administrative
Agent that adequate and fair means do not exist for ascertaining the applicable
interest rate on the basis provided for in the definition of Eurodollar Rate,
the Administrative Agent shall forthwith so notify the Borrowers and the
Lenders, whereupon (A) each Eurodollar Rate Advance will automatically, on the
last day of the then existing Interest Period therefor, Convert into a Base Rate
Advance, and (B) the obligation of the Lenders to make, or to Convert Advances
into, Eurodollar Rate Advances shall be suspended until the Administrative Agent
shall notify the Borrowers and the Lenders that the circumstances causing such
suspension no longer exist.

     

    (d) If the
applicable Borrower shall fail to select the duration of any Interest Period for
any Eurodollar Rate Advances in accordance with the provisions contained in the
definition of “Interest Period” in Section 1.01, the Administrative Agent will
forthwith so notify such Borrower and the Lenders and such Advances will
automatically, on the last day of the then existing Interest Period therefor,
Convert into Base Rate Advances.

     

    (e) On the
date on which the aggregate unpaid principal amount of Eurodollar Rate Advances
comprising any Borrowing shall be reduced, by payment or prepayment or
otherwise, to less than $10,000,000, such Advances shall automatically Convert
into Base Rate Advances.

     

    (f) Upon the
occurrence and during the continuance of any Event of Default, (i) each
Eurodollar Rate Advance will automatically, on the last day of the then existing
Interest Period therefor, Convert into a Base Rate Advance and (ii) the
obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate
Advances shall be suspended.

     

    SECTION
2.11. Optional
Conversion of Advances.

     

    Each
Borrower may on any Business Day, upon notice given to the Administrative Agent
not later than 12:00 noon on the third Business Day prior to the date of the
proposed Conversion and subject to the provisions of Sections 2.10 and 2.14,
Convert all or any part of Advances made to such Borrower of one Type comprising
the same Borrowing into Advances of the other Type or of the same Type but
having a new Interest Period; provided, however, that any Conversion
of Eurodollar Rate Advances into Base Rate Advances shall be made only on the
last day of an Interest Period for such Eurodollar Rate Advances, any Conversion
of Base Rate Advances into Eurodollar Rate Advances shall be in an amount not
less than the minimum amount specified in Section 2.02(b) and no Conversion of
any Advances shall result in more separate Borrowings than permitted under
Section 2.02(b).  Each such notice of a Conversion shall, within the
restrictions specified above, specify (i) the date of such Conversion, (ii) the
Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate
Advances, the duration of the initial Interest Period for each such
Advance.  Each notice of Conversion shall be irrevocable and binding
on the applicable Borrower.  This Section shall not apply to Swingline
Borrowings, which may not be Converted.

     

    SECTION
2.12. Optional
Prepayments of Advances.

     

    Each
Borrower may, upon notice not later than 11:00 A.M. (i) at least two Business
Days’ prior to the date of prepayment, in the case of Eurodollar Rate Advances
and (ii) on the date of prepayment, in the case of Base Rate Advances and
Swingline Advances, to the Administrative Agent (and, in the case of a Swingline
Advance, the Swingline Bank) stating the proposed date and aggregate principal
amount of the prepayment, and, if such notice is given, such Borrower shall
prepay the outstanding principal amount of the Advances made to such Borrower
comprising part of the same Borrowing in whole or ratably in part, together with
accrued interest to the date of such prepayment on the principal amount prepaid;
provided, however, that (x) each
partial prepayment shall be in an aggregate principal amount of $5,000,000 or an
integral multiple of $1,000,000 in excess thereof and (y) in the event of any
such prepayment of a Eurodollar Rate Advance, the applicable Borrower shall be
obligated to reimburse the Lenders in respect thereof pursuant to Section
8.04(c).

     

    SECTION
2.13. Increased
Costs.

     

    (a) If, due
to any Regulatory Change, there shall be any increase in the cost to any Lender
of agreeing to make or making, funding or maintaining any Extension of Credit
(excluding for purposes of this Section 2.13 any such increased costs resulting
from (i) Taxes or Other Taxes (as to which Section 2.16 shall govern) and (ii)
changes in the basis of taxation of overall net income or overall gross income
by the United States or by the foreign jurisdiction or state under the laws of
which such Lender is organized or has its Applicable Lending Office or any
political subdivision thereof), then AEP shall from time to time, promptly upon
demand by such Lender (with a copy of such demand to the Administrative Agent),
pay to the Administrative Agent for the account of such Lender additional
amounts sufficient to compensate such Lender for such increased
cost.  Each Lender will promptly notify AEP of any determination made
by it referred to above, but the failure to give such notice shall not affect
such Lender’s right to compensation, provided, however, that AEP shall not
be required to pay such additional amounts in respect of any Regulatory Change
for any period ending prior to the date that is 180 days prior to the giving of
the notice of the determination of such additional amounts (unless such period
shall have commenced after the date that such Lender notified AEP that
additional amounts were payable as a result of such Regulatory Change); except,
if such Regulatory Change shall have been imposed retroactively, for the period
from the effective date of such Regulatory Change to the date that is 180 days
after the first date on which such Lender reasonably should have had knowledge
of such Regulatory Change.

     

    (b) If any
Lender determines that any Regulatory Change affects or would affect the amount
of capital required or expected to be maintained by such Lender or any
corporation controlling such Lender and that the amount of such capital is
increased by or based upon the existence of such Lender’s commitment to make
Extensions of Credit hereunder and other commitments of this type, then, upon
demand by such Lender (with a copy of such demand to the Administrative Agent),
AEP shall pay to the Administrative Agent for the account of such Lender,
promptly upon demand from time to time and as specified by such Lender,
additional amounts sufficient to compensate such Lender or such corporation in
the light of such circumstances, to the extent that such Lender reasonably
determines such increase in capital to be allocable to the existence of such
Lender’s commitment to make Extensions of Credit hereunder; provided, however, that AEP shall not
be required to pay such additional amounts in respect of any Regulatory Change
for any period ending prior to the date that is 180 days prior to the making of
such Lender’s initial request for such additional amounts (unless such period
shall have commenced after the date that such Lender notified AEP that
additional amounts were payable as a result of such Regulatory Change); except,
if such Regulatory Change shall have been imposed retroactively, for the period
from the effective date of such Regulatory Change to the date that is 180 days
after the first date on which such Lender reasonably should have had knowledge
of such Regulatory Change.

     

    (c) In making
the determinations contemplated by Sections 2.13(a) and (b), each Lender may
make such estimates, assumptions, allocations and the like that such Lender in
good faith determines to be appropriate, and such Lender’s selection thereof in
accordance with this Section 2.13(c), and the determinations made by such Lender
on the basis thereof, shall be final, binding and conclusive upon AEP, except,
in the case of such determinations, for manifest errors in computation or
transmission.  Each Lender shall furnish to AEP upon request a
certificate explaining the basis for any amounts claimed by it under Section
2.13(a) or (b), provided, that no Lender
shall be required to disclose in any such certificate any confidential
information relating to such Lender or any Person controlling such
Lender.

     

    SECTION
2.14. Illegality.

     

    If due to
any Regulatory Change it shall become unlawful or impossible for any Lender (or
its Eurodollar Lending Office) to make, maintain or fund its Eurodollar Rate
Advances, and such Lender shall so notify the Administrative Agent, the
Administrative Agent shall forthwith give notice thereof to the other Lenders
and the Borrowers, whereupon, until such Lender notifies the Borrowers and the
Administrative Agent that the circumstances giving rise to such suspension no
longer exist, the obligation of such Lender to make Eurodollar Rate Advances, or
to Convert outstanding Advances into Eurodollar Rate Advances, shall be
suspended.  Before giving any notice to the Administrative Agent
pursuant to this Section 2.14, such Lender shall use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions
applicable to such Lender) to designate a different Eurodollar Lending Office if
such designation would avoid the need for giving such notice and would not, in
the judgment of such Lender, be otherwise disadvantageous to such
Lender.  If such notice is given, each Eurodollar Rate Advance of such
Lender then outstanding shall be converted to a Base Rate Advance either (i) on
the last day of the then current Interest Period applicable to such Eurodollar
Rate Advance if such Lender may lawfully continue to maintain and fund such
Advance to such day or (ii) immediately if such Lender shall determine that it
may not lawfully continue to maintain and fund such Advance to such
day.

     

    SECTION
2.15. Payments
and Computations.

     

    (a) Each
Borrower shall make each payment to be made by it hereunder not later than 1:00
P.M. on the day when due in Dollars to the Administrative Agent at the Agent’s
Account (except payments to be made directly to the Swingline Bank as expressly
provided herein) in same day funds without condition or deduction for any
counterclaim, defense, recoupment or setoff.  The Administrative Agent
will promptly thereafter cause to be distributed like funds relating to the
payment of principal or interest or commitment fees ratably (other than amounts
payable pursuant to Section 2.09(c), 2.13, 2.16 or 8.04(c)) to the Lenders for
the account of their respective Applicable Lending Offices, and like funds
relating to the payment of any other amount payable to any Lender to such Lender
for the account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement.  In the event that such
payment is required to be returned to such Borrower for any reason, each Lender
will return to the Administrative Agent any portion thereof previously
distributed to such Lender.  Upon its acceptance of an Assignment and
Acceptance and recording of the information contained therein in the Register
pursuant to Section 8.07(c), from and after the effective date specified in such
Assignment and Acceptance, the Administrative Agent shall make all payments
hereunder in respect of the interest assigned thereby to the Lender assignee
thereunder, and the parties to such Assignment and Acceptance shall make all
appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.

     

    (b) Each
Borrower hereby authorizes each Lender, if and to the extent payment owed to
such Lender is not made by such Borrower when due hereunder, after any
applicable grace period, to charge from time to time against any or all of such
Borrower’s accounts with such Lender any amount so due.

     

    (c) All
computations of interest based on the rate referred to in clause (i) of the
definition of the “Base Rate” contained in Section 1.01 shall be made by the
Administrative Agent on the basis of a year of 365 or 366 days, as the case may
be, and all computations of interest based on the Eurodollar Rate or the Federal
Funds Rate and of commitment fees and LC Fees shall be made by the
Administrative Agent on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest, commitment fees or LC Fees are
payable.  Each determination by the Administrative Agent of an
interest rate hereunder shall be conclusive and binding for all purposes, absent
manifest error.

     

    (d) Whenever
any payment hereunder shall be stated to be due on a day other than a Business
Day, such payment shall be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the computation of payment
of interest or commitment fees, as the case may be; provided, however, that, if
such extension would cause payment of interest on or principal of Eurodollar
Rate Advances to be made in the next following calendar month, such payment
shall be made on the next preceding Business Day.

     

    (e) Unless
the Administrative Agent shall have received notice from any Borrower prior to
the date on which any payment is due from such Borrower to a Lender hereunder
that such Borrower will not make such payment in full, the Administrative Agent
may assume that such Borrower has made such payment in full to the
Administrative Agent on such date, and the Administrative Agent may, in reliance
upon such assumption, cause to be distributed to each Lender on such due date an
amount equal to the amount then due such Lender.  If and to the extent
that such Borrower shall not have so made such payment in full to the
Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at the Federal Funds Rate.

     

    SECTION
2.16. Taxes.

     

    (a) Any and
all payments by each Borrower hereunder shall be made, in accordance with
Section 2.15, free and clear of and without deduction for any and all present or
future Taxes, excluding, in the case of each Lender and the Administrative
Agent, Bank Taxes.  If any Borrower shall be required by law to deduct
any Taxes from or in respect of any sum payable by such Borrower hereunder to
any Lender or the Administrative Agent, (i) the sum payable shall be increased
as may be necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 2.16) such
Lender or the Administrative Agent (as the case may be) receives an amount equal
to the sum it would have received had no such deductions been made, (ii) such
Borrower shall make such deductions and (iii) such Borrower shall, to the
fullest extent permitted by Applicable Law, pay the full amount deducted to the
relevant taxation authority or other authority in accordance with Applicable
Law.

     

    (b) In
addition, each Borrower shall pay any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies that
arise from any payment made by such Borrower hereunder or from the execution,
delivery or registration of, performing under, or otherwise with respect to,
this Agreement (hereinafter referred to as “Other
Taxes”).

     

    (c) Each
Borrower shall indemnify each Lender and the Administrative Agent for and hold
it harmless against the full amount of Taxes or Other Taxes attributable to such
Borrower (including, without limitation, taxes of any kind imposed by any
jurisdiction on amounts payable by such Borrower under this Section 2.16), but
excluding Bank Taxes, imposed on or paid by such Lender or the Administrative
Agent (as the case may be) and any liability (including penalties, interest and
expenses that do not arise from such Lender’s failure timely to give notice
thereof or request payment pursuant to this Section 2.16) arising therefrom or
with respect thereto.  This indemnification shall be made within 30
days from the date such Lender or the Administrative Agent (as the case may be)
makes written demand therefor.

     

    (d) Within 30
days after the date of any payment by any Borrower of Taxes, such Borrower shall
furnish to the Administrative Agent, at its address referred to in Section 8.02,
the original or a certified copy of a receipt evidencing such
payment.  In the case of any payment hereunder by or on behalf of such
Borrower through an account or branch outside the United States or by or on
behalf of such Borrower by a payor that is not a United States person, if such
Borrower determines that no Taxes are payable in respect thereof, such Borrower
shall furnish, or shall cause such payor to furnish, to the Administrative
Agent, at such address, an opinion of counsel reasonably acceptable to the
Administrative Agent stating that such payment is exempt from
Taxes.  For purposes of this subsection (d) and subsection (e), the
terms “United States” and “United States person” shall have the meanings
specified in Section 7701 of the Internal Revenue Code.

     

    (e) Each
Lender organized under the laws of a jurisdiction outside the United States, on
or prior to the date of its execution and delivery of this Agreement in the case
of each Initial Lender and on the date of the Assignment and Acceptance pursuant
to which it becomes a Lender in the case of each other Lender, and from time to
time thereafter as requested in writing by AEP (but only so long as such Lender
remains lawfully able to do so), shall provide each of the Administrative Agent
and AEP with two original Internal Revenue Service Form W-8BEN or W-8ECI, as
appropriate, or any successor or other form prescribed by the Internal Revenue
Service, certifying that such Lender is exempt from or entitled to a reduced
rate of United States withholding tax on payments pursuant to this
Agreement.  If the form provided by a Lender at the time such Lender
first becomes a party to this Agreement indicates a United States interest
withholding tax rate in excess of zero, withholding tax at such rate shall be
considered excluded from Taxes unless and until such Lender provides the
appropriate forms certifying that a lesser rate applies, whereupon withholding
tax at such lesser rate only shall be considered excluded from Taxes for periods
governed by such form; provided, however, that, if at the date
of the Assignment and Acceptance pursuant to which a Lender assignee becomes a
party to this Agreement, the Lender assignor was entitled to payments under
subsection (a) in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term Taxes shall include
(in addition to withholding taxes that may be imposed in the future or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Lender assignee on such date.  If any
form or document referred to in this subsection (e) requires the disclosure of
information, other than information necessary to compute the tax payable and
information required on the date hereof by Internal Revenue Service Form W-8BEN
or W-8ECI, that the Lender reasonably considers to be confidential, the Lender
shall give notice thereof to AEP and shall not be obligated to include in such
form or document such confidential information.

     

    (f) For any
period with respect to which a Lender has failed to provide AEP with the
appropriate form described in Section 2.16(e) (other than if such failure is due
to a change in law occurring subsequent to the date on which a form originally
was required to be provided, or if such form otherwise is not required under
subsection (e) above), such Lender shall not be entitled to indemnification
under Section 2.16(a) or (c) with respect to Taxes imposed by the United States
by reason of such failure; provided, however, that
should a Lender become subject to Taxes because of its failure to deliver a form
required hereunder, the relevant Borrower shall take such steps as the Lender
shall reasonably request to assist the Lender to recover such
Taxes.

     

    SECTION
2.17. Sharing
of Payments, Etc.

     

    If any
Lender shall obtain any payment (whether voluntary, involuntary, through the
exercise of any right of set-off, or otherwise) on account of the Advances owing
to it by any Borrower or participations in Swingline Advances or Letters of
Credit (other than pursuant to Section 2.09(c), 2.13, 2.16 or 8.04(c) or in
respect of Eurodollar Rate Advances converted into Base Rate Advances pursuant
to Section 2.14) with respect to such Borrower, in excess of its ratable share
of payments on account of the Advances to such Borrower and participations in
Swingline Advances and Letters of Credit, obtained by all the Lenders, such
Lender shall forthwith purchase from the other Lenders such participations in
such Advances owing to them and participations in Swingline Advances and Letters
of Credit as shall be necessary to cause such purchasing Lender to share the
excess payment ratably with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender’s ratable share (according to the
proportion of (i) the amount of such Lender’s required repayment to (ii) the
total amount so recovered from the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered.  Each Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 2.17 may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Lender were the direct creditor of such Borrower in the amount of such
participation.

Borrower is a corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction in which it is incorporated or otherwise
organized, and each Significant Subsidiary of such Borrower is duly organized,
validly existing and in good standing under the laws of the jurisdiction in

    (c) This
Agreement has been duly executed and delivered by such Borrower.  This
Agreement is the legal, valid and binding obligation of such Borrower
enforceable against such Borrower in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, fraudulent
conveyance or other similar laws affecting the enforcement of creditors’ rights
in general, and except as the availability of the remedy of specific performance
is subject to general principles of equity (regardless of whether such remedy is
sought in a proceeding in equity or at law) and subject to requirements of
reasonableness, good faith and fair dealing.

     

    (d) No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or any other third party is
required for the due execution, delivery and performance by such Borrower of
this Agreement, except for such Governmental Approvals that may be required to

for the account of such Borrower, each of which Governmental Approvals will have
been obtained and will be in full force and effect on or prior to the date of

    (e) There is
no pending or threatened action, suit, investigation, litigation or proceeding,
including, without limitation, any Environmental Action, affecting such Borrower
or any of its Significant Subsidiaries before any court, governmental agency or

as disclosed in the Disclosure Documents.

     

    (f) The
consolidated balance sheet of each Borrower and its Consolidated Subsidiaries as
at December 31, 2007, and the related consolidated statements of income and cash
flows of such Borrower and its Consolidated Subsidiaries for the fiscal year
then ended, accompanied by an opinion of Deloitte & Touche LLP, an

Borrower.

     

    (g) No
written statement, information, report, financial statement, exhibit or schedule
furnished by or on behalf of such Borrower to the Administrative Agent, any
Lender or any LC Issuing Bank in connection with the syndication or negotiation
of this Agreement or included herein or delivered pursuant hereto contained,
contains, or will contain any material misstatement of fact or intentionally
omitted, omits, or will omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were,
are, or will be made, not misleading.

     

    (h) Except as
disclosed in the Disclosure Documents, such Borrower and each Significant
Subsidiary of such Borrower is in material compliance with all laws (including
ERISA and Environmental Laws) rules, regulations and orders of any governmental
authority applicable to it.

     

    (i) No
accumulated funding deficiency (as defined in Section 302 of ERISA and Section
412 of the Internal Revenue Code) that could reasonably be expected to have a
Material Adverse Effect, whether or not waived, exists with respect to any
Plan.  Such Borrower has not incurred, and does not presently expect
to incur, any withdrawal liability under Title IV of ERISA with respect to any
Multiemployer Plan that could reasonably be expected to have a Material Adverse
Effect.  Such Borrower and each of its ERISA Affiliates have complied
in all material respects with ERISA and the Internal Revenue
Code.  Such Borrower and each of its Subsidiaries have complied in all
material respects with foreign law applicable to its Foreign Plans, if
any.  As used herein, the term “Plan”
shall mean an “employee pension benefit plan” (as defined in Section 3 of ERISA)
which is and has been established or maintained, or to which contributions are
or have been made or should be made according to the terms of the plan by any
Borrower or any of its ERISA Affiliates.  The term “Multiemployer
Plan” shall mean any Plan which is a “multiemployer plan” (as such term
is defined in Section 4001(a)(3) of ERISA).  The term “Foreign
Plan” shall mean any pension, profit-sharing, deferred compensation, or
other employee benefit plan, program or arrangement maintained by any entity
subsidiary which, under applicable local foreign law, is required to be funded
through a trust or other funding vehicle.

Borrower and its Subsidiaries have filed or caused to be filed all material
Federal, state and local tax returns that are required to be filed by them, and
have paid or caused to be paid all material taxes shown to be due and payable on
such returns or on any assessments received by them (to the extent that such
taxes and assessments have become due and payable) other than those taxes
contested in good faith and for which adequate reserves have been established in
accordance with GAAP.

     

    (k) Such
Borrower is not engaged in the business of extending credit for the purpose of
buying or carrying Margin Stock, and no proceeds of any Advance will be used to
buy or carry any Margin Stock or to extend credit to others for the purpose of
buying or carrying any Margin Stock.  Not more than 25% of the assets
of such Borrower subject to the restrictions of Section 5.02(a), (c) or (d)
constitutes Margin Stock.

     

    (l) Neither
such Borrower nor any Significant Subsidiary of such Borrower is an “investment
company,” or an “affiliated person” of, or “promoter” or “principal underwriter”
for, an “investment company,” as such terms are defined in the Investment
Company Act of 1940, as amended.  Neither the making of any Extension
of Credit, the application of the proceeds or repayment thereof by such Borrower
nor the consummation of the other transactions contemplated hereby will violate
any provision of such Act or any rule, regulation or order of the SEC
thereunder.

     

    (m) All
Significant Subsidiaries of such Borrower as of the date hereof are listed on
Schedule 4.01(m) hereto.

V

    COVENANTS
OF THE BORROWERS

     

    SECTION
5.01. Affirmative
Covenants.

     

    So long
as any Advance or any other amount payable hereunder shall remain unpaid, any
Letter of Credit shall remain outstanding or any Lender shall have any
Commitment hereunder, each Borrower will:

     

    (a) Preservation of
Existence, Etc.  Preserve and maintain, and cause each
Significant Subsidiary of such Borrower to preserve and maintain, its corporate,
partnership or limited liability company (as the case may be) existence and all
material rights (charter and statutory) and franchises; provided, however, that each Borrower
and any Significant Subsidiary of such Borrower may consummate any merger or
consolidation permitted under Section 5.02(a); and provided further that neither such
Borrower nor any Significant Subsidiary of such Borrower shall be required to
preserve any right or franchise if (i) the board of directors of such Borrower
or such Significant Subsidiary, as the case may be, shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
such Borrower or such Significant Subsidiary, as the case may be, and that the
loss thereof is not disadvantageous in any material respect to such Borrower or
such Significant Subsidiary, as the case may be, or to the Lenders; (ii)
required in connection with or pursuant to any Restructuring Law; or (iii)
required in connection with the RTO Transaction; and provided further, that no Significant
Subsidiary of any Borrower shall be required to preserve and maintain its
corporate existence if (x) the loss thereof is not disadvantageous in any
material respect to such Borrower or to the Lenders or (y) required in
connection with or pursuant to any Restructuring Law or (z) required in
connection with the RTO Transaction.

     

    (b) Compliance with
Laws, Etc.  Comply, and cause each Significant Subsidiary of
such Borrower to comply, in all material respects, with Applicable Law, with
such compliance to include, without limitation, compliance with ERISA and
Environmental Laws.

     

    (c) Performance and
Compliance with Other Agreements.  Perform and comply, and
cause each Significant Subsidiary of such Borrower to perform and comply, with
the provisions of each indenture, credit agreement, contract or other agreement
by which it is bound, the non-performance or non-compliance with which would
result in a Material Adverse Change.

     

    (d) Inspection
Rights.  At any reasonable time and from time to time, permit
the Administrative Agent, any LC Issuing Bank or any Lender or any agents or

the date hereof (other than the election or nomination of an individual whose
initial assumption of office is in connection with an actual or threatened
election contest relating to the election of the directors of AEP) shall be, for
purposes of this provision, considered as though such person were a member of
the board as of the date hereof (which shall constitute an Event of Default for
all Borrowers); or (iii) AEP shall fail to own directly or indirectly 100% of
the common equity of any other Borrower (which shall constitute an Event of
Default for such Borrower); or

Subsidiary of such Borrower and either (i) enforcement proceedings shall have

Administrative Agent determines that any funds held in the LC Collateral Account
are subject to any right or claim of any Person other than the Administrative
Agent, the Lenders and the LC Issuing Banks or that the total amount of such
funds is less than 103% of the aggregate undrawn stated amounts of all Letters
of Credit that are outstanding on such date, such Borrower will, forthwith upon
demand by the Administrative Agent, pay to the Administrative Agent, as
additional funds to be deposited and held in the LC Collateral Account, an
amount equal to the excess of (i) 103% of such aggregate undrawn stated amounts
of all Letters of Credit that are outstanding on such date over (ii) the total
amount of funds, if any, then held in the LC Collateral Account that the
Administrative Agent determines to be free and clear of any such right and
claim.  Upon the drawing of any Letter of Credit for which funds are
on deposit in the LC Collateral Account, such funds shall be applied to
reimburse the relevant LC Issuing Bank or Lender holding a participation in the
reimbursement obligation of such Borrower to such LC Issuing Bank to the extent
permitted by applicable law.

    THE
ADMINISTRATIVE AGENT

     

    SECTION
7.01. Authorization
and Action.

     

    Each
Lender hereby appoints and authorizes the Administrative Agent to take such
action as agent on its behalf and to exercise such powers and discretion under
this Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers and discretion as are reasonably incidental
thereto.  As to any matters expressly provided for in this Agreement
as being subject to the discretion of the Administrative Agent, such matters
shall be subject to the sole discretion of the Administrative Agent, its
directors, officers, agents and employees.  As to any matters not
expressly provided for by this Agreement (including, without limitation,
enforcement or collection of the outstanding Borrowings), the Administrative
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Lenders, and such instructions shall be binding upon all Lenders; provided, however, that the
Administrative Agent shall not be required to take any action that exposes the
Administrative Agent to personal liability or that is contrary to this Agreement
or Applicable Law.  The Administrative Agent agrees to give to each
Lender prompt notice of each notice given to it by any Borrower pursuant to the
terms of this Agreement.

     

    SECTION
7.02. Agent’s
Reliance, Etc.

     

    Neither
the Administrative Agent nor any of its respective directors, officers, agents
or employees shall be liable for any action taken or omitted to be taken by it
or them under or in connection with this Agreement, except for its or their own
gross negligence or willful misconduct.  Without limitation of the
generality of the foregoing, the Administrative Agent:  (i) may treat
each Lender recorded in the Register as the owner of the Commitment recorded for
such Lender in the Register until the Administrative Agent receives and accepts
an Assignment and Acceptance entered into by such Lender, as assignor, and an
Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult
with legal counsel (including counsel for the Borrowers), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants or experts; (iii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations (whether written or oral) made in or
in connection with this Agreement; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement on the part of any Lender or to inspect the
property (including the books and records) of any Lender; (v) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, this Agreement or any
other instrument or document furnished pursuant thereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telegram,
telecopy or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

     

    SECTION
7.03. JPMCB
and its Affiliates.

     

    With
respect to its Commitments and the Advances made by it, JPMCB shall have the
same rights and powers under this Agreement as any other Lender and may exercise
the same as though it were not the Administrative Agent; and the term “Lender”
or “Lenders” shall, unless otherwise expressly indicated, include JPMCB in its
individual capacity.  JPMCB and its Affiliates may accept deposits
from, lend money to, act as trustee under indentures of, accept investment
banking engagements from and generally engage in any kind of business with, any
Lender, any of its Subsidiaries and any Person who may do business with or own
securities of any Lender or any such Subsidiary, all as if JPMCB were not the
Administrative Agent and without any duty to account therefor to the
Lenders.

     

    SECTION
7.04. Lender
Credit Decision.

     

    Each
Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on the financial statements
referred to in Section 4.01 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement.  Each Lender also acknowledges that it will, independently
and without reliance upon the Administrative Agent or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement.

     

    SECTION
7.05. Indemnification.

     

    Each
Lender severally agrees to indemnify the Administrative Agent (to the extent not
promptly reimbursed by the Borrowers) from and against such Lender’s ratable
share (determined as provided below) of any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by, or asserted against the Administrative Agent in any way relating to or
arising out of this Agreement or any action taken or omitted by the
Administrative Agent under this Agreement; provided, however, that no Lender shall
be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Administrative Agent’s gross negligence or willful
misconduct.  Without limitation of the foregoing, each Lender agrees
to reimburse the Administrative Agent promptly upon demand for its ratable share
of any costs and expenses (including, without limitation, fees and reasonable
expenses of counsel) payable by AEP under Section 8.04, to the extent that the
Administrative Agent is not promptly reimbursed for such costs and expenses by
AEP after request therefor.  For purposes of this Section 7.05, the
Lenders’ respective ratable shares of any amount shall be determined, at any
time, according to the sum of (i) the aggregate principal amount of the Advances
outstanding at such time and owing to the respective Lenders and (ii) the
aggregate unused portions of their respective Commitments at such
time.  In the event that any Lender shall have failed to make any
Advance as required hereunder, such Lender’s Commitment shall be considered to
be unused for purposes of this Section 7.05 to the extent of the amount of such
Advance.  The failure of any Lender to reimburse the Administrative
Agent promptly upon demand for its ratable share of any amount required to be
paid by the Lender to the Administrative Agent as provided herein shall not
relieve any other Lender of its obligation hereunder to reimburse the
Administrative Agent for its ratable share of such amount, but no Lender shall
be responsible for the failure of any other Lender to reimburse the
Administrative Agent for such other Lender’s ratable share of such
amount.  Without prejudice to the survival of any other agreement of
any Lender hereunder, the agreement and obligations of each Lender contained in
this Section 7.05 shall survive the payment in full of principal, interest and
all other amounts payable hereunder.

     

    SECTION
7.06. Successor
Agent.

     

    The
Administrative Agent may resign at any time by giving written notice thereof to
the Lenders and the Borrowers and may be removed at any time with or without
cause by the Required Lenders.  Upon any such resignation or removal,
the Required Lenders shall have the right to appoint a successor Agent to the
Administrative Agent that has resigned or been removed.  If no
successor Administrative Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after the
retiring Administrative Agent’s giving of notice of resignation or the Required
Lenders’ removal of such retiring Administrative Agent, then such retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws
of the United States or of any State thereof and having a combined capital and
surplus of at least $500,000,000.  Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Agent, such
successor Administrative Agent shall succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations under this Agreement. After any retiring Administrative Agent’s
resignation or removal hereunder as Administrative Agent, the provisions of this
Article VII shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.

    SECTION
8.01. Amendments,
Etc.

     

    No
amendment or waiver of any provision of this Agreement, nor consent to any
departure by any Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Required Lenders and the affected
Borrowers, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided, however, that no amendment,
waiver or consent shall, unless in writing and signed by all the Lenders, do any
of the following: (i) amend Section 3.01 or 3.02 or waive any of the conditions
specified therein, (ii) increase the Commitment of any Lender, extend the
Commitments, increase any Borrower Sublimit or subject any Lender to any
additional obligations, (iii) reduce the principal of, or interest on, the
outstanding Advances or any fees or other amounts payable hereunder, (iv)
postpone any date fixed for any payment of principal of, or interest on, the
outstanding Advances, reimbursement obligations or any fees or other amounts
payable hereunder, (v) change the percentage of the Commitments or of the
aggregate unpaid principal amount of the outstanding Borrowings, or the number
or the percentage of Lenders, that shall be required for the Lenders or any of
them to take any action hereunder or (vi) amend or waive this Section 8.01 or
any provision of this Agreement that requires pro rata treatment of the Lenders;
and provided further that no amendment,
waiver or consent shall, unless in writing and signed by the Administrative
Agent, the Swingline Bank or any LC Issuing Bank in addition to the Lenders
required above to take such action, affect the rights or duties of the
Administrative Agent, the Swingline Bank or such LC Issuing Bank, as the case
may be, under this Agreement.  Notwithstanding the foregoing, any
provision of this Agreement may be amended by an agreement in writing entered
into by the Borrowers, the Required Lenders and the Administrative Agent if (i)
by the terms of such agreement the Commitment of each Lender or LC Issuing Bank
not consenting to the amendment provided for therein shall terminate (but such
Lender or LC Issuing Bank shall continue to be entitled to the benefits of
Sections 2.13, 2.16 and 8.04) upon the effectiveness of such amendment and (ii)
at the time such amendment becomes effective, each Lender or LC Issuing Bank not
consenting thereto receives payment in full of the principal amount of and
interest accrued on each Advance made by it or any Letter of Credit issued by it
and outstanding, as the case may be, and all other amounts owing to it or
accrued for its account under this Agreement and is released from its
obligations hereunder.

    (b) The
Borrowers and the Lenders hereby agree that the Administrative Agent may make
any information required to be delivered under Section 5.01(i)(i), (ii), (iv)
and (v) (the “Communications”)
available to the Lenders by posting the Communications on Intralinks or a
substantially similar electronic transmission systems (the “Platform”).  The
Borrowers and the Lenders hereby acknowledge that the distribution of material
through an electronic medium is not necessarily secure and that there are
confidentiality and other risks associated with such distribution.

     

    (c) THE
PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”.  THE AGENT PARTIES
(AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE
COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY
FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS.  NO WARRANTY OF ANY
KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY
OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF
THIRD-PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE
AGENT PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE
PLATFORM.  IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS
AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ADVISORS OR REPRESENTATIVES (COLLECTIVELY, “AGENT
PARTIES”) HAVE ANY LIABILITY TO ANY BORROWER, ANY LENDER OR ANY OTHER
PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT
OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES
(WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF ANY BORROWER’S OR THE
ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET,
EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL,
NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED
PRIMARILY FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT.

     

    The
Administrative Agent agrees that the receipt of the Communications by the
Administrative Agent at its e-mail address set forth above shall constitute
effective delivery of the Communications to the Administrative Agent for
purposes of the Loan Documents.  Each Lender agrees that notice to it
(as provided in the next sentence) specifying that the Communications have been
posted to the Platform shall constitute effective delivery (if received during
such Lender’s normal business hours) of the Communications to such Lender for
purposes of the Loan Documents.  Each Lender agrees (i) to notify
the Administrative Agent in writing (including by electronic communication) from
time to time of such Lender’s e-mail address to which the foregoing notice may
be sent by electronic transmission and (ii) that the foregoing notice may
be sent to such e-mail address.

     

    Nothing
herein shall prejudice the right of the Administrative Agent or any Lender to
give any notice or other communication pursuant to any Loan Document in any
other manner specified in such Loan Document.

     

    SECTION
8.03. No
Waiver; Remedies.

     

    No
failure on the part of any Lender or the Administrative Agent to exercise, and
no delay in exercising, any right hereunder shall operate as a waiver thereof;
nor shall any single or partial exercise of any such right preclude any other or
further exercise thereof or the exercise of any other right.  The
remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

     

    SECTION
8.04. Costs
and Expenses.

     

    (a) AEP
agrees to pay promptly upon demand all reasonable out-of-pocket costs and
expenses of the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification and amendment of this
Agreement and the other documents to be delivered hereunder, including, without
limitation, (i) all due diligence, syndication (including printing, distribution
and bank meetings), transportation, computer, duplication, appraisal,
consultant, and audit expenses and (ii) the reasonable fees and expenses of
counsel for the Administrative Agent with respect thereto and with respect to
advising the Administrative Agent as to its rights and responsibilities under
this Agreement.  AEP further agrees to pay promptly upon demand all
costs and expenses of the Administrative Agent and the Lenders, if any
(including, without limitation, counsel fees and expenses), in connection with
the enforcement (whether through negotiations, legal proceedings or otherwise)
of this Agreement and the other documents to be delivered hereunder, including,
without limitation, reasonable fees and expenses of counsel for the
Administrative Agent and the Lenders in connection with the enforcement of
rights under this Section 8.04(a).

     

    (b) AEP
agrees to indemnify and hold harmless each Lender, the Administrative Agent, the
Swingline Bank, the LC Issuing Banks and each of their respective Affiliates and
their officers, directors, controlling persons, employees, agents and advisors
(each, an “Indemnified
Party”) from and against any and all claims, damages, losses and
liabilities, joint or several, to which any such Indemnified Party may become
subject, in each case arising out of or in connection with or relating to
(including, without limitation, in connection with any investigation, litigation
or proceeding or preparation of a defense in connection therewith) (i) this
Agreement, any of the transactions contemplated herein or the actual or proposed
use of the proceeds of the Extensions of Credit or (ii) the actual or alleged
presence of Hazardous Materials on any property of any Borrower or any of its
Subsidiaries or any Environmental Action relating in any way to any Borrower or
any of its Subsidiaries, and to reimburse any Indemnified Party for any and all
reasonable expenses (including, without limitation, reasonable fees and expenses
of counsel) as they are incurred in connection with the investigation of or
preparation for or defense of any pending or threatened claim or any action or
proceeding arising therefrom, whether or not such Indemnified Party is a party
and whether or not such claim, action or proceeding is initiated or brought by
or on behalf of such Borrower or any of its Affiliates and whether or not any of
the transactions contemplated hereby are consummated or this Agreement is
terminated, except to the extent such claim, damage, loss, liability or expense
is found in a judgment by a court of competent jurisdiction to have resulted
from such Indemnified Party’s gross negligence or willful
misconduct.  In the case of an investigation, litigation or other
proceeding to which the indemnity in this Section 8.04(b) applies, such
indemnity shall be effective whether or not such investigation, litigation or
proceeding is brought by any Borrower, its directors, shareholders or creditors
or an Indemnified Party or any other Person or any Indemnified Party is
otherwise a party thereto and whether or not the transactions contemplated
hereby are consummated.  Each Borrower agrees not to assert any claim
against the Administrative Agent, any Lender, any of their respective
Affiliates, or any of their respective directors, officers, employees, attorneys
and agents, on any theory of liability, for special, indirect, consequential or
punitive damages arising out of or otherwise relating to this Agreement, any of
the transactions contemplated herein or the actual or proposed use of the
proceeds of the Extensions of Credit.

     

    (c) If any
payment of principal of, or Conversion of, any Eurodollar Rate Advance is made
by any Borrower to or for the account of a Lender other than on the last day of
the Interest Period for such Advance, as a result of a payment or Conversion
pursuant to Section 2.07, 2.10(e), 2.13 or 2.15, acceleration of the maturity of
the outstanding Borrowings pursuant to Section 6.01 or for any other reason (in
the case of any such payment or Conversion), such Borrower shall, promptly upon
demand by such Lender (with a copy of such demand to the Administrative Agent),
pay to the Administrative Agent for the account of such Lender any amounts
required to compensate such Lender for any additional losses, costs or expenses
that it may reasonably incur as a result of such payment or Conversion,
including, without limitation, any loss (other than loss of Applicable Margin),
cost or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by any Lender to fund or maintain such
Advance.

     

    (d) Without
prejudice to the survival of any other agreement of the Borrowers hereunder, the
respective agreements and obligations of the Borrowers contained in Sections
2.14, 2.17 and 8.04 shall survive the payment in full of principal, interest and
all other amounts payable hereunder.

     

    (e) Each
Borrower agrees that no Indemnified Party shall have any liability (whether
direct or indirect, in contract or tort or otherwise) to such Borrower or its
respective security holders or creditors related to or arising out of or in
connection with this Agreement, the Extensions of Credit or the use or proposed
use of the proceeds thereof, any of the transactions contemplated by any of the
foregoing or in the loan documentation and the performance by an Indemnified
Party by any of the foregoing except to the extent that any loss, claim, damage,
liability or expense is found in a judgment by a court of competent jurisdiction
to have resulted from such Indemnified Party’s gross negligence or willful
misconduct.

     

    (f) In the
event that an Indemnified Party is requested or required to appear as a witness
in any action brought by or on behalf of or against any Borrower or any of its
Affiliates in which such Indemnified Party is not named as a defendant, such
Borrower agrees to reimburse such Indemnified Party for all reasonable expenses
incurred by it in connection with such Indemnified Party’s appearing and
preparing to appear as such a witness, including, without limitation, the fees
and disbursements of its legal counsel.

     

    SECTION
8.05. Right
of Set-off.

     

    Upon (i)
the occurrence and during the continuance of any Event of Default with respect
to a Borrower and (ii) the making of the request or the granting of the consent
specified by Section 6.01 to authorize the Administrative Agent to declare the
outstanding Borrowings of such Borrower due and payable pursuant to the
provisions of Section 6.01, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender or such Affiliate to or for the credit or the account
of such Borrower against any and all of the obligations of such Borrower now or
hereafter existing under this Agreement held by such Lender, whether or not such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured.  Each Lender agrees promptly to notify
such Borrower after any such set-off and application, provided that the failure to
give such notice shall not affect the validity of such set-off and
application.  The rights of each Lender and its Affiliates under this
Section are in addition to other rights and remedies (including, without
limitation, other rights of set-off) that such Lender and its Affiliates may
have.

     

    SECTION
8.06. Binding
Effect.

     

    This
Agreement shall become effective when it shall have been executed by the
Borrowers and the Administrative Agent and when the Administrative Agent shall
have been notified by each Initial Lender that such Initial Lender has executed
it and thereafter shall be binding upon and inure to the benefit of the
Borrowers, the Administrative Agent, each Lender, the Swingline Bank and each LC
Issuing Bank and their respective successors and assigns, except that no
Borrower shall have the right to assign its rights hereunder or any interest
herein without the prior written consent of all of the Lenders.

     

    SECTION
8.07. Assignments
and Participations.

     

    (a) Each
Lender may, with the written consent (unless such assignment is to a Lender, a
wholly owned Affiliate of such Lender or a wholly owned Affiliate of the
assigning Lender, in which case no such consent, and only notice to the
Administrative Agent and AEP shall be required) of the Administrative Agent, AEP
(unless a Default shall have occurred and be continuing), the Swingline Bank and
each LC Issuing Bank (in each case, with each consent not to be unreasonably
withheld), assign to one or more Persons all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment and the Advances owing to it); provided, however, that (i) each such
assignment shall be of a constant, and not a varying, percentage of all rights
and obligations under this Agreement, (ii) except in the case of an assignment
to a Person that, immediately prior to such assignment, was a Lender or an
assignment of all of a Lender’s rights and obligations under this Agreement, the
amount of the Commitment of the assigning Lender being assigned pursuant to each
such assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $10,000,000 or an
integral multiple of $1,000,000 in excess thereof, (iii) each such assignment
shall be to an Eligible Assignee, and (iv) the parties to each such assignment
shall execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with a
processing and recordation fee of $3,500 (to be paid by the assigning Lender or,
in the case of an assignment pursuant to Section 8.07(i), AEP).  Upon
such execution, delivery, acceptance and recording, from and after the effective
date specified in each Assignment and Acceptance, (x) the assignee thereunder
shall be a party hereto and, to the extent that rights and obligations hereunder
have been assigned to it pursuant to such Assignment and Acceptance, have the
rights and obligations of a Lender hereunder and (y) the Lender assignor
thereunder shall, to the extent that rights and obligations hereunder have been
assigned by it pursuant to such Assignment and Acceptance, relinquish its rights
and be released from its obligations under this Agreement (and, in the case of
an Assignment and Acceptance covering all or the remaining portion of an
assigning Lender’s rights and obligations under this Agreement, such Lender
shall cease to be a party hereto).

     

    (b) By
executing and delivering an Assignment and Acceptance, the Lender assignor
thereunder and the assignee thereunder confirm to and agree with each other and
the other parties hereto as follows:  (i) other than as provided in
such Assignment and Acceptance, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto; (ii) such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition of any
Borrower or the performance or observance by any Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such assigning Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such assignee confirms that it is an Eligible
Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers and
discretion under this Agreement as are delegated to the Administrative Agent by
the terms hereof, together with such powers and discretion as are reasonably
incidental thereto; and (vii) such assignee agrees that it will perform in
accordance with their terms all of the obligations that by the terms of this
Agreement are required to be performed by it as a Lender.

     

    (c) Upon its
receipt of an Assignment and Acceptance executed by an assigning Lender and an
assignee representing that it is an Eligible Assignee, the Administrative Agent
shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C hereto, accept such Assignment and
Acceptance, record the information contained therein in the Register and forward
a copy thereof to the Borrowers.

     

    (d) The
Administrative Agent shall maintain at its address referred to in Section 8.02 a
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and, the
Commitment of, and principal amount of the Advances owing to, each Lender by
each Borrower from time to time (the “Register”).  The
entries in the Register shall be conclusive and binding for all purposes, absent
manifest error, and each Borrower, the Administrative Agent and the Lenders may
treat each Person whose name is recorded in the Register as a Lender hereunder
for all purposes of this Agreement.  The Register shall be available
for inspection by each Borrower, the Administrative Agent or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

     

    (e) Each
Lender may sell participations to one or more banks or other entities (other
than the Borrowers or any of their Affiliates) in or to all or a portion of its
rights and/or obligations under this Agreement (including, without limitation,
all or a portion of its Commitment and the Advances) without the consent of AEP,
the Administrative Agent or any Lender; provided, however, that (i) such
Lender’s obligations under this Agreement (including, without limitation, its
Commitment hereunder) shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) each Borrower, the Administrative Agent, the Swingline Bank,
the LC Issuing Banks and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and
obligations under this Agreement and (iv) no Lender shall be entitled to receive
any greater amount pursuant to Section 2.13 or 2.16 than such Lender would have
been entitled to receive had such Lender not sold such
participation.  No Lender may grant to any holder of a participation
in the rights and obligations of such Lender hereunder the right to require such
Lender to take or omit to take any action under this Agreement, except that such
Lender may grant to any such holder the right to require such holder’s consent
to (i) reduce the principal of or interest on the outstanding Borrowings or the
fees or other amounts payable to such Lender hereunder, (ii) postpone any date
fixed for any payment of principal of or interest on the outstanding Borrowings
or the fees payable to such Lender hereunder or (iii) permit any Borrower to
assign any of its obligations under this Agreement to any other
Person.  Each holder of a participation in any rights and obligations
under this Agreement, if and to the extent the applicable participation
agreement so provides, shall, with respect to such participation, be entitled to
all of the rights of a Lender as fully as though it were a Lender under Sections
2.09(c), 2.13, 2.16 8.01, 8.04(b) and 8.04(c) (subject to any conditions imposed
on each Lender hereunder with respect thereto, including delivery of the forms
and certificates required under Section 2.16(e)); provided, however, that no holder of a
participation shall be entitled to any amounts that would otherwise be payable
to it with respect to its participation under Section 2.13(a) or 2.16 unless (x)
such amounts are payable in respect of a Regulatory Change enacted after the
date the applicable participation agreement was executed or (y) such amounts
would have been payable to the Lender that granted such participation if such
participation had not been granted.  Each Lender selling or granting a
participation shall indemnify each Borrower and the Administrative Agent for any
liabilities for Taxes that such Borrower or the Administrative Agent, as the
case may be, might incur as a result of such Lender’s failure to withhold and
pay any Taxes applicable to payments by such Lender to its participant in
respect of such participation.

     

    (f) Notwithstanding
anything to the contrary contained herein, any Lender (a “Granting
Lender”) may grant to a special purpose funding vehicle (an “SPV”) of
such Granting Lender identified as such in writing from time to time by the
Granting Lender to the Administrative Agent and the Borrowers, the option to
provide to any Borrower all or any part of any Advance that such Granting Lender
would otherwise be obligated to make to such Borrower pursuant to this
Agreement; provided
that (i) nothing herein shall constitute a commitment by any such SPV to make
any Advance, (ii) if such SPV elects not to exercise such option or otherwise
fails to provide all or any part of such Advance, the Granting Lender shall be
obligated to make such Advance pursuant to the terms hereof and (iii) no SPV or
Granting Lender shall be entitled to receive any greater amount pursuant to
Section 2.09(c), 2.13 or 2.16 than the Granting Lender would have been entitled
to receive had the Granting Lender not otherwise granted such SPV the option to
provide any Advance to such Borrower.  The making of an Advance by an
SPV hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Advance were made by such Granting
Lender.  Each party hereto hereby agrees that no SPV shall be liable
for any indemnity or similar payment obligation under this Agreement for which a
Lender would otherwise be liable so long as, and to the extent that, the related
Granting Lender provides such indemnity or makes such payment.  In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior indebtedness of any SPV, it will not institute against or
join any other Person in instituting against such SPV any bankruptcy,
reorganization, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State
thereof.  Notwithstanding the foregoing, the Granting Lender
unconditionally agrees to indemnify each Borrower, the Administrative Agent and
each Lender against all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be incurred by or asserted against such Borrower,
the Administrative Agent or such Lender, as the case may be, in any way relating
to or arising as a consequence of any such forbearance or delay in the
initiation of any such proceeding against its SPV.  Each party hereto
hereby acknowledges and agrees that no SPV shall have the rights of a Lender
hereunder, such rights being retained by the applicable Granting
Lender.  Accordingly, and without limiting the foregoing, each party
hereby further acknowledges and agrees that no SPV shall have any voting rights
hereunder and that the voting rights attributable to any Advance made by an SPV
shall be exercised only by the relevant Granting Lender and that each Granting
Lender shall serve as the administrative agent and attorney-in-fact for its SPV
and shall on behalf of its SPV receive any and all payments made for the benefit
of such SPV and take all actions hereunder to the extent, if any, such SPV shall
have any rights hereunder.  In addition, notwithstanding anything to
the contrary contained in this Agreement any SPV may (i) with notice to, but
without the prior written consent of any other party hereto, assign all or a
portion of its interest in any Advances to the Granting Lender and (ii) in
accordance with Section 8.08, disclose on a confidential basis any Confidential
Information relating to its Advances to any rating agency, commercial paper
dealer or provider of any surety, guarantee or credit or liquidity enhancement
to such SPV.  This Section may not be amended without the prior
written consent of each Granting Lender, all or any part of whose Advance is
being funded by an SPV at the time of such amendment.

     

    (g) Any
Lender may, in connection with any assignment, designation, participation or
grant to an SPV or proposed assignment, designation, participation or grant to
an SPV pursuant to this Section 8.07, disclose to the assignee, designee or
participant or proposed assignee, designee or participant, any information
relating to any Borrower furnished to such Lender by or on behalf of such
Borrower; provided
that, prior to any such disclosure, the assignee, designee or participant or
proposed assignee, designee or participant shall agree to preserve the
confidentiality of any Confidential Information relating to any Borrower
received by it from such Lender.

     

    (h) Notwithstanding
any other provision set forth in this Agreement, any Lender may at any time
create a security interest in all or any portion of its rights under this
Agreement in favor of any Federal Reserve Bank in accordance with Regulation A
of the Board of Governors of the Federal Reserve System.

     

    (i) In the
event that any Lender, or any participant of such Lender pursuant to Section
8.07(e), shall have delivered a notice or certificate pursuant to Section 2.14,
or any Borrower shall be required to make additional payments to any Lender
under Section 2.09(c), 2.13 or 2.16, AEP shall have the right, at its own
expense, upon notice to such Lender, to require such Lender to transfer and
assign without recourse (in accordance with and subject to the restrictions
contained in this Section 8.07) all such Lender’s interests, rights and
obligations under this Agreement to another Eligible Assignee identified by AEP
and approved by the Administrative Agent, the Swingline Bank and each LC Issuing
Bank (which approval shall not be unreasonably withheld), which financial
institution shall assume such obligations of such Lender for consideration equal
to the outstanding principal amount of such Lender’s Advances, and if
satisfactory arrangements are made for the payment to such Lender of interest
and fees accrued hereunder to the date of such transfer and all other amounts
payable hereunder to such Lender on or prior to the date of such transfer; provided that (i) no Default
shall have occurred and be continuing, (ii) no such assignment shall conflict
with any law, rule or regulation or order of any governmental authority and
(iii) the relevant Borrower shall have paid to the assignor in immediately
available funds on or prior to the date of such assignment all amounts accrued
for the account of such Lender or owed to it under Section 2.09(c), 2.13 or
2.16.

     

    SECTION
8.08. Confidentiality.

     

    Neither
the Administrative Agent nor any Lender shall disclose any Confidential
Information to any other Person without the consent of AEP, other than (i) to
the Administrative Agent’s or such Lender’s Affiliates and their officers,
directors, employees, agents and advisors, to the Administrative Agent or a
Lender and, as contemplated by Section 8.07, to actual or prospective assignees
and participants, and then only on a confidential basis, (ii) as required by any
law, rule or regulation or judicial process, (iii) to any rating agency when
required by it, or to any rating agency, commercial paper dealer or provider of
any surety, guarantee or credit or liquidity enhancement in connection with a
grant to an SPV under Section 8.07(f), provided, that, prior to any
such disclosure, such rating agency, commercial paper dealer or provider shall
undertake to preserve the confidentiality of any Confidential Information
received by it from such Lender, (iv) as requested or required by any state,
federal or foreign authority or examiner regulating banks, banking or other
financial institutions and (v) to direct or indirect counterparties in
connection with swaps or derivatives, and then only on a confidential
basis.

    SECTION
8.12. Jurisdiction,

    (a) Each of
the parties hereto hereby irrevocably and unconditionally submits, for itself

or federal court of the United States of America sitting in New York, New York,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard
and determined in any such New York State court or, to the extent permitted by
law, in such federal court.  Each of the parties hereto agrees that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.  Nothing in this Agreement shall affect any right
that any party may otherwise have to bring any action or proceeding relating to

    (b) Each of

    SECTION
8.13. Waiver

relating to this Agreement or the actions of the Administrative Agent, any LC
Issuing Bank, the Swingline Bank, the Borrowers or any Lender in the
negotiation, administration, performance or enforcement thereof.

     

    SECTION
8.14. USA
Patriot Act.

     

    Each
Lender and LC Issuing Bank hereby notifies the Borrowers that pursuant to the
requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into
law as of October 26, 2001)) (as amended, restated, modified or otherwise
supplemented from time to time, the “Act”), it is required to obtain, verify and
record information that identifies the Borrowers, which information includes the
name and address of each Borrower and other information that will allow such
Lender or LC Issuing Bank, as the case may be, to identify such Borrower in
accordance with the Act.

     

    SECTION
8.15.  No
Fiduciary Duty. 

     

    Each of
the Administrative Agent, each Lender, the Swingline Bank, the LC Issuing Banks
and each of their respective Affiliates and their officers, directors,
controlling persons, employees, agents and advisors (collectively, solely for
purposes of this Section 8.15, the “Lenders”) may have economic interests that
conflict with those of the Borrowers.  The Borrowers agree that nothing in
the Loan Documents or otherwise will be deemed to create an advisory, fiduciary
or agency relationship or fiduciary or other implied duty between the Lenders
and any Borrower, its stockholders or its Affiliates.  Each Borrower
acknowledges and agrees that (i) the transactions contemplated by the Loan
Documents are arm’s-length commercial transactions between the Lenders, on the
one hand, and the Borrowers, on the other, (ii) in connection therewith and with
the process leading to such transaction each of the Lenders is acting solely as
a principal and not the agent or fiduciary of any Borrower, its management,
stockholders, creditors or any other person, (iii) no Lender has assumed an
advisory or fiduciary responsibility in favor of any Borrower with respect to
the transactions contemplated hereby or the process leading thereto
(irrespective of whether any Lender or any of its Affiliates has advised or is
currently advising any Borrower on other matters) or any other obligation to any
Borrower except the obligations expressly set forth in the Loan Documents and
(iv) each Borrower has consulted its own legal and financial advisors to the
extent it deemed appropriate.  Each Borrower further acknowledges and
agrees that it is responsible for making its own independent judgment with
respect to such transactions and the process leading thereto.  Each
Borrower agrees that it will not claim that any Lender has rendered advisory
services of any nature or respect, or owes a fiduciary or similar duty to any
Borrower, in connection with such transaction or the process leading
thereto.

    To each
of the Lenders party to the

    Credit
Agreement referred to below

    and to
JPMorgan Chase Bank, N.A.,

    as
Administrative Agent thereunder

    


    [Date]

    


    Ladies
and Gentlemen:

    


    This
opinion is furnished to you pursuant to Section 3.01(a)(iii) of the Credit
Agreement, dated as of April 4, 2008 (the “Credit
Agreement”) among AEP Texas Central Company, AEP Texas North Company,
American Electric Power Company, Inc., Appalachian Power Company, Columbus
Southern Power Company (“CSPC”),
Indiana Michigan Power Company, Kentucky Power Company, Ohio Power Company
(“OPC”),
Public Service Company of Oklahoma and Southwestern Electric Power Company
(collectively, the “Borrowers”),
the Lenders party thereto, the LC Issuing Banks party thereto and JPMorgan Chase
Bank, N.A., as Administrative Agent for the Lenders and LC Issuing
Banks.  Terms defined in the Credit Agreement are used herein as
therein defined.

    


    I am an
Associate General Counsel for American Electric Power Service Corporation, an
affiliate of the Borrowers, and have acted as counsel to the Borrowers in
connection with the preparation, execution and delivery of the Credit
Agreement.  I am generally familiar with the Borrowers’ corporate
history, properties, operations and charter (including amendments, restatements
and supplements thereto).

    


    In
connection with this opinion, I, or attorneys over whom I exercise supervision,
have examined:

    


    
      	
              (1)  

            	
              The
      Credit Agreement.

            


    

    


    
      	
              (2)  

            	
              The
      documents furnished by the Borrowers pursuant to Article III of the Credit
      Agreement.

            


    

    


    
      	
              (3)  

            	
              The
      certificates of incorporation of the Borrowers and all amendments
      thereto.

            


    

    


    
      	
              (4)  

            	
              The
      by-laws of the Borrowers and all amendments
  thereto.

            


    

    


    
      	
              (5)  

            	
              Certificates
      of the Secretary of State or equivalent officer of each state in which a
      Borrower is incorporated or otherwise formed, dated as of a recent date,
      attesting to the continued existence and good standing of the Borrowers
      incorporated or otherwise formed in that
State.

            


    

    


    In
addition, I, or attorneys over whom I exercise supervision, have examined the
originals, or copies certified to my satisfaction, of such other corporate
records of the Borrowers, certificates of public officials and of officers of
the Borrowers, and agreements, instruments and other documents, as I have deemed
necessary as a basis for the opinions expressed below.

     

    In my
examination, I, or attorneys over whom I exercise supervision, have assumed the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals and the conformity
with the originals of all documents submitted to us as copies.  In
making our examination of documents and instruments executed or to be executed
by persons other than the Borrowers, I, or attorneys over whom I exercise
supervision, have assumed that each such other person had the requisite power
and authority to enter into and perform fully its obligations thereunder, the
due authorization by each such other person for the execution, delivery and
performance thereof and the due execution and delivery thereof by or on behalf
of such person of each such document and instrument.  In the case of
any such person that is not a natural person, I, or attorneys over whom I
exercise supervision, have also assumed, insofar as it is relevant to the
opinions set forth below, that each such other person is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it was
created and is duly qualified and in good standing in each other jurisdiction
where the failure to be so qualified could reasonably be expected to have a
material effect upon its ability to execute, deliver and/or perform its
obligations under any such document or instrument.  I, or attorneys
over whom I exercise supervision, have further assumed that each document,
instrument, agreement, record and certificate reviewed by us for purposes of
rendering the opinions expressed below has not been amended by any oral
agreement, conduct or course of dealing between the parties
thereto.

     

    As to
questions of fact material to the opinions expressed herein, I have relied upon
certificates and representations of officers of the Borrowers (including but not
limited to those contained in the Credit Agreement and certificates delivered
upon the execution and delivery of the Credit Agreement) and of appropriate
public officials, without independent verification of such matters except as
otherwise described herein.

     

    Whenever
my opinions herein with respect to the existence or absence of facts are stated
to be to my knowledge or awareness, it is intended to signify that no
information has come to my attention or the attention of other counsel working
under my direction in connection with the preparation of this opinion letter
that would give me or them actual knowledge of the existence or absence of such
facts.  However, except to the extent expressly set forth herein,
neither I nor they have undertaken any independent investigation to determine
the existence or absence of such facts, and no inference as to my or their
knowledge of the existence or absence of such facts should be
assumed.

     

    I am a
member of the Bar of the States of New York and Ohio and do not purport to be
expert on the laws of any jurisdiction other than the laws of the States of New
York and Ohio and the Federal laws of the United States.  My opinions
expressed below are limited to the law of the States of New York and Ohio and
the Federal law of the United States.

    


    Based
upon the foregoing and upon such investigation as I have deemed necessary, and
subject to the limitations, qualifications and assumptions set forth herein, I
am of the following opinion:

    


    
      	
              1.  

            	
              Each
      Borrower (a) is a corporation duly organized, validly existing and in good
      standing under the laws of the state of its incorporation or formation;
      (b) has the corporate power and authority, and the legal right, to own and
      operate its property, to lease the property which it operates as lessee
      and to conduct the business in which it is currently engaged and in which
      it proposes to be engaged after the date hereof; (c) is duly qualified as
      a foreign corporation and is in good standing under the laws of each
      jurisdiction where its ownership, lease or operation of property or the
      conduct of its business requires such qualification, except any such
      jurisdiction where the failure to so qualify could not, in the aggregate,
      reasonably be expected to result in a Material Adverse Change; (d) owns or
      possesses all material licenses and permits necessary for the operation by
      it of its business as currently conducted; and (e) is in compliance with
      all Requirements of Law, except as disclosed in the Disclosure Documents
      referenced in Section 4.01(e) of the Credit Agreement or to the extent
      that the failure to comply therewith could not, in the aggregate,
      reasonably be expected to have a Material Adverse Effect.  The
      term “Requirements of Law” means the laws of the State of Ohio and the
      laws, rules and regulations of the United States of America (including,
      without limitation, ERISA and Environmental Laws) and orders of any
      governmental authority applicable to the
  Borrowers.

            


    

    


    
      	
              2.  

            	
              Each
      Borrower has the corporate power and authority, and the legal right, to
      execute and deliver the Credit Agreement and to perform under, and to
      borrow under, the Credit Agreement.  Each Borrower has taken all
      necessary corporate action to authorize the execution, delivery and
      performance of the Credit Agreement and the incurrence of Advances on the
      terms and conditions of the Credit Agreement, and the Credit Agreement has
      been duly executed and delivered by each of the
  Borrowers.

            


    

    


    
      	
              3.  

            	
              The
      execution, delivery and performance of the Credit Agreement and the
      Advances made thereunder will not violate any Requirements of Law, any
      Borrower's certificate of incorporation or by-laws, or any material
      contractual restriction binding on or affecting such Borrower or any of
      its properties.

            


    

    


    
      	
              4.  

            	
              Except
      as required with respect to CSPC and OPC pursuant to Section 3.03 of the
      Credit Agreement, no approval or authorization or other action by, and
      notice to or filing with, any governmental agency or regulatory body or
      other third person is required in connection with the due execution and
      delivery of the Credit Agreement and the performance, validity or
      enforceability of the Credit
Agreement.

            


    

    


    
      	
              5.  

            	
              Except
      as described in Section 4.01(e) of the Credit Agreement, no action, suit,
      investigation, litigation, or proceeding, including, without limitation,
      any Environmental Action, affecting the Borrowers or any of their
      Significant Subsidiaries before any court, government agency or arbitrator
      is pending or, to my knowledge, threatened, that is reasonably likely to
      have a Material Adverse Effect.

            


    

    


    
      	
              6.  

            	
              No
      Borrower nor any of their respective Significant Subsidiaries is an
      “investment company”, or an “affiliated person” of, or “promoter” or
      “principal underwriter” for, an “investment company”, as such terms are
      defined in the Investment Company Act of 1940, as
      amended.  Neither the making of any Advances, the application of
      the proceeds or repayment thereof by the Borrowers nor the consummation of
      the other transactions contemplated by the Credit Agreement will violate
      any provision of such Act or any rule, regulation or order of the
      Securities and Exchange Commission
thereunder.

            


    

    


    
      	
               
      

            	
              7.  
      

            	
              In
      any action or proceeding arising out of or relating to the Credit
      Agreement in any court of the State of Ohio or in any Federal court
      sitting in the State of Ohio, such court would recognize and give effect
      to the provisions of Section 8.09 of the Credit Agreement, wherein the
      parties thereto agree that the Credit Agreement shall be governed by, and
      construed in accordance with, the laws of the State of New
      York.  However, if a court of the State of Ohio or a Federal
      court sitting in the State of Ohio were to hold that the Credit Agreement
      is governed by, and to be construed in accordance with, the laws of the
      State of Ohio, the Credit Agreement would be, under the State of Ohio, the
      legal, valid and binding obligation of the Borrowers enforceable against
      the Borrowers in accordance with its
terms.

            


    

     

    The
opinion set forth above in the last sentence of paragraph 7 above is subject to
the effect of any applicable bankruptcy, insolvency, reorganization, moratorium
or similar laws affecting creditor’s rights generally and to general principles
of equity, including (without limitation) concepts of materiality,
reasonableness, good faith and fair dealing (regardless of whether considered in
a proceeding in equity or at law.)

    


    I express
no opinion as to (i) Section 8.05 of the Credit Agreement; (ii) the effect of
the law of any jurisdiction (other than the State of Ohio) wherein any Lender
may be located which limits the rates of interest which may be charged or
collected by such Lender; and (iii) whether a Federal or state court outside of
the States of New York or Ohio would give effect to the choice of New York law
provided for in the Credit Agreement.


    
      
         


      

      
         


        
          

        

      

      
         


      

    


    This
opinion has been rendered solely for your benefit in connection with the Credit
Agreement and the transactions contemplated thereby and may not be used,
circulated, quoted, relied upon or otherwise referred to by any other person
(other than your respective counsel, auditors and any regulatory agency having
jurisdiction over you or as otherwise required pursuant to legal process or
other requirements of law) for any other purpose without my prior written
consent; provided that
(i) King & Spalding LLP, special counsel for the Administrative Agent, may
rely on the opinions expressed in this opinion letter in connection with the
opinion to be furnished by them in connection with the transactions contemplated
by the Credit Agreement and (ii) any Person that becomes a Lender or an LC
Issuing Bank after the date hereof may rely on the opinions expressed in this
opinion letter as though addressed to such Person.  I undertake no
responsibility to update or supplement this opinion in response to changes in
law or future events or circumstances.

    


    Very
truly yours,

Berkemeyer

    


    



    
      
         


      

      
         


        
          

        

      

      
         


      

    


    EXHIBIT

    (to

    FORM
OF OPINION OF COUNSEL

    FOR
THE ADMINISTRATIVE AGENT

     

    [DATE]

     

    To each
of the Lenders party to the

    Credit Agreement referred to
below

    and to JPMorgan Chase Bank,
N.A.,

     

    as Administrative Agent

     

    American
Electric Power Company, Inc.

     

    Ladies
and Gentlemen:

     

    We have
acted as special New York counsel to JPMorgan Chase Bank, N.A., individually and
as Administrative Agent, in connection with the preparation, execution and
delivery of the Credit Agreement, dated as of April 4, 2008 (the “Credit
Agreement”), among AEP Texas Central Company, AEP Texas North Company,
American Electric Power Company, Inc., Appalachian Power Company, Columbus
Southern Power Company, Indiana Michigan Power Company, Kentucky Power Company,
Ohio Power Company, Public Service Company of Oklahoma and Southwestern Electric
Power Company (collectively, the “Borrowers”),
the Lenders party thereto, the LC Issuing Banks party thereto and JPMorgan Chase
Bank, N.A., as Administrative Agent for the Lenders and LC Issuing
Banks.  Terms defined in the Credit Agreement are used herein as
therein defined.  This opinion is furnished to you pursuant to Section
3.01(a)(iv) of the Credit Agreement.  Unless otherwise indicated,
terms defined in the Credit Agreement are used herein as therein
defined.

     

    In that
connection, we have examined the following documents:

     

    (1)           Counterparts
of the Credit Agreement, executed by the Borrowers, the Administrative Agent,
the LC Issuing Banks and the Lenders; and

     

    (2)           The
other documents furnished by the Borrowers pursuant to Section 3.01 of the
Credit Agreement, including (without limitation) the opinion of Thomas G.
Berkemeyer, Associate General Counsel for American Electric Power Service
Corporation, an affiliate of the Borrowers (the “Opinion”).

     

    In our
examination of the documents referred to above, we have assumed the authenticity
of all such documents submitted to us as originals, the genuineness of all
signatures, the due authority of the parties executing such documents and the
conformity to the originals of all such documents submitted to us as
copies.  We have assumed that you independently evaluated, and are
satisfied with, the creditworthiness of the Borrowers and the business terms
reflected in the Credit Agreement.  We have also assumed that each of
the Lenders and the Administrative Agent has duly executed and delivered, with
all necessary power and authority (corporate and otherwise), the Credit
Agreement.

     

    To the
extent that our opinions expressed below involve conclusions as to matters
governed by law other than the law of the State of New York, we have relied upon
the Opinion and have assumed without independent investigation the correctness
of the matters set forth therein, our opinions expressed below being subject to
the assumptions, qualifications and limitations set forth in the
Opinion.  We note that we do not represent the Borrowers and,
accordingly, are not privy to the nature or character of their
businesses.  Accordingly, we have also assumed that the Borrowers are
subject only to statutes, rules, regulations, judgments, orders, and other
requirements of law of general applicability to corporations doing business in
the State of New York.  As to matters of fact, we have relied solely
upon the documents we have examined.

     

    Based
upon the foregoing, and subject to the qualifications set forth below, we are of
the opinion that:

     

    (i)           The
Credit Agreement is the legal, valid and binding obligation of the Borrowers
enforceable against the Borrowers in accordance with its terms.

     

    (ii)           While
we have not independently considered the matters covered by the Opinion to the
extent necessary to enable us to express the conclusions stated therein, the
Opinion and the other documents referred to in item (2) above are substantially
responsive to the corresponding requirements set forth in Section 3.01 of the
Credit Agreement pursuant to which the same have been delivered.

     

    Our
opinions are subject to the following qualifications:

     

    (a) Our
opinion in paragraph (i) above is subject to the effect of any applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or
similar law affecting creditors’ rights generally.

     

    (b) Our
opinion in paragraph (i) above is subject to the effect of general principles of
equity, including (without limitation) concepts of materiality, reasonableness,
good faith and fair dealing (regardless of whether considered in a proceeding in
equity or at law).  Such principles of equity are of general
obligation, and, in applying such principles, a court, among other things, might
not allow a contracting party to exercise remedies in respect of a default
deemed immaterial, or might decline to order an obligor to perform
covenants.

     

    (c) We note
further that, in addition to the application of equitable principles described
above, courts have imposed an obligation on contracting parties to act
reasonably and in good faith in the exercise of their contractual rights and
remedies, and may also apply public policy considerations in limiting the right
of parties seeking to obtain indemnification under circumstances where the
conduct of such parties in the circumstances in question is determined to have
constituted negligence.

     

    (d) We
express no opinion herein as to (i) Section 8.05 of the Credit Agreement, (ii)
the enforceability of provisions purporting to grant to a party conclusive
rights of determination, (iii) the availability of specific performance or other
equitable remedies, (iv) the enforceability of rights to indemnity under Federal
or state securities laws and (v) the enforceability of waivers by parties of
their respective rights and remedies under law.

     

    (e) Our
opinions expressed above are limited to the law of the State of New York, and we
do not express any opinion herein concerning any other law.  Without
limiting the generality of the foregoing, we express no opinion as to the effect
of the law of any jurisdiction other than the State of New York wherein any
Lender may be located or wherein enforcement of the Credit Agreement may be
sought that limits the rates of interest legally chargeable or
collectible.

     

    The
foregoing opinion is solely for your benefit and may not be relied upon by any
other Person other than any Person that may become a Lender under the Credit
Agreement after the date hereof.

     

    Very
truly yours,
