Mr. Michael J. Kolosowsky
First Union National Bank
One First Union Center
301 South College Street, TW-5
Charlotte, NC 28288-0735

Dear Michael:

          Pursuant to our conversations, First Union National Bank (the "Bank")
is making available to PP&L Capital Funding, Inc. (the "Company") a line of
credit in the aggregate principal amount of $80,000,000.00 (the "Facility").
The Facility will commence on the date hereof and terminate on July 7, 1999 (the
"Termination Date"), unless sooner terminated in accordance herewith or with the
Note (as hereinafter defined); provided that the Termination Date may be
extended from the initial or any extended Termination Date upon written request
of the Company to the Bank not more than 45 days nor less than 30 days prior to
the Termination Date, and approval of such extension by the Bank.

          Approval of any such extension shall be in the sole discretion of the
Bank.  The Bank's approval of such extension shall be provided by written notice
to the Company specifying the date to which the Termination Date is extended.
Notwithstanding the foregoing, the Termination Date shall in no event be
extended to a date that is more than 364 days from the date of such notice.
Failure of the Bank to provide written notice of approval of such extension
shall be deemed to mean that the Facility is not so extended.

          Borrowings under this Facility shall become due and payable without
setoff, counterclaim or deduction whatsoever on the date selected by the Company
in the Request (as hereinafter defined) with respect to each advance, not later
than the Termination Date, and will be evidenced by a promissory note in the
form of Exhibit A attached hereto (the "Note").  Provided that the aggregate
principal amount outstanding at any one time does not exceed $80,000,000.00,
borrowings may be effected using either of the following alternatives:

   1. Domestic Dollar Loans maturing not later than the Termination Date,
      bearing an annual interest rate equal to the higher of

          (i)  the Bank's floating prime lending rate (calculated on the basis
               of a 365-day year) as announced from time to time (which rate
               shall not necessarily be the lowest or best rate offered by the
               Bank at such time); and

          (ii) .5% in excess of the Bank's overnight Federal Funds Rate
               (calculated on the basis of a 360-day year) which shall mean the
               per annum rate at which the Bank can acquire federal funds in the
               interbank overnight federal funds market;

      this rate (the "Base Rate") to be determined daily; or
<PAGE>
 
                                    Page 2

   2. Eurodollar Loans with maturities of one, two, or three months (but in no
      event shall a Eurodollar Loan mature later than the Termination Date),
      bearing an annual interest rate (calculated on the basis of a 360-day year
      for the actual number of days elapsed) equal to .30% over the London
      interbank Offered Rate, as determined by the Bank, for periods and in
      amounts corresponding to the terms of such Eurodollar Loans two London
      business days prior to the date of the requested advance, such
      determination to be made by the Bank in its normal and customary manner.

          Interest on each Domestic Dollar Loan and Eurodollar Loan
(individually a "Loan" and collectively the "Loans") is due and payable at the
maturity thereof and, if such maturity is longer than one month, at one month
intervals after the making of such Loan.  Domestic Dollar Loans shall be
prepayable at any time without premium or penalty.  In the event the Company
repays any Eurodollar Loan on any day other than the last day of an interest
period therefor (whether by acceleration or otherwise), the Company shall pay to
the Bank, on demand, any resulting loss or expense incurred by the Bank
including, without limitation, any loss or expense incurred in obtaining,
liquidating or employing deposits from third parties.  All amounts not paid when
due on any Loan (whether by acceleration or otherwise) will bear interest
payable on demand at a rate equal to 1% in excess of the Base Rate.

          The Bank expressly reserves the right to suspend offering Eurodollar
Loans if the Bank determines that making or maintaining any such Loan shall have
become impracticable or unlawful or if the effective cost thereof to the Bank
shall exceed the quoted rate of interest with respect thereto.

BORROWING NOTIFICATION AND FUNDING PROVISIONS

          Minimum drawdowns for all Loans made under this Facility shall be
$10,000,000.00 or whole multiples of $1,000,000 in excess thereof.  Loans
hereunder may be effected by telephone request ("Request") by those individuals
authorized to request such Loans as designated in writing to the Bank by the
Company's Treasurer.  A request for any Loan is deemed as confirmation by the
Company that no event as described in paragraph 2 of the Note shall have
occurred and be continuing and that all representations and warranties contained
in this letter agreement are true as of the date of the borrowing as if made on
such date.  Upon receipt of such Request or as provided for in the following
paragraph, the Bank shall transfer the amount of the Loan in immediately
available funds to the Company's Account Number 28065 with Mellon Bank,
Delaware, ABA No. 031100047 or such other bank account of the Company as may be
directed in writing by the Company's Treasurer.

          For Domestic Dollar Loans, the Company may initiate a Loan by
providing a Request prior to 11:00 A.M. on the date on which the funds are
required.  For Eurodollar Loans, the Company may initiate a Loan by providing a
Request prior to 11:00 A.M. at least three business days prior to the date on
which the funds are required.

LOAN DOCUMENTATION

          The Bank shall record all borrowings and repayments of principal and
interest and the dates of such transactions on its records.  The Company agrees
that the Bank's records, barring manifest evidence to the contrary, shall
conclusively evidence the Company's outstanding obligations under the terms of
this letter agreement and Note.

FACILITY FEE

          The Company agrees to pay to the Bank a facility fee (the "Fee") of
 .10% per annum on the aggregate amount of the Facility.  This Fee, which shall
be based on the actual 
<PAGE>
 
                                    Page 3

number of days elapsed on a 360-day year, shall begin to accrue on the date
hereof and shall be payable in arrears on the last business day of each calendar
quarter and on any date on which the Bank's commitment hereunder shall be
terminated in full.

          All payments made by the Company under this letter agreement or the
Note will be made to the Bank at One First Union Center, 5th Floor, 301 South
College Street, Charlotte, North Carolina 28288 or such other address as the
Bank may designate.

CANCELLATION

          The Company, in its sole discretion, may cancel the whole or any part
of the unused portion of the Facility in $10,000,000.00 increments by giving the
Bank not less than 10 business days prior notice to that effect, specifying the
date and amount of the proposed cancellation.

REPRESENTATIONS AND WARRANTIES

          The Company has full power and authority to enter into this letter
agreement, to execute and deliver the Note and to incur the obligations provided
for herein and therein, all of which have been duly authorized by all proper and
necessary corporate action.

          Except as provided by applicable laws of bankruptcy, insolvency,
liquidation, or other laws of general application: (i) this letter agreement
constitutes, and the Note, when issued and delivered pursuant hereto, will
constitute valid and legally binding obligations of the Company, enforceable in
accordance with their terms; and (ii) the Loans will rank pari passu in respect
of priority of payment with all other senior unsecured indebtedness of the
Company.

          The execution, delivery and performance of its obligations under this
Agreement and the Note will not violate in any material respect any provisions
of any agreement to which the Company is bound and will not be in conflict with,
result in a breach of, or constitute (with due notice and/or lapse of time) a
default under any such agreement or result in the creation or imposition of any
lien, charge or encumbrance of any nature whatsoever upon any of the properties
or assets of the Company.

          The audited balance sheet of PP&L Resources, Inc. ("Resources"),
parent corporation of the Company, on a consolidated basis as of December 31,
1997 together with audited statements of income and expense, retained earnings,
paid in capital and surplus and changes in financial position, together with
notes thereto, for the fiscal year then ended, heretofore delivered to the Bank,
fairly present the financial condition of Resources and its consolidated
subsidiaries (including the Company) and the results of their operations, as of
the date and for the period referred to and have been prepared in accordance
with generally accepted accounting principles consistently maintained throughout
the period involved.  There has been no material adverse change in the business,
properties, condition (financial or other) or operations of Resources or any of
its subsidiaries since the date of such audited financial statements which would
adversely affect Resources' ability to meet its obligations under the terms of a
Guarantee of even date by Resources of the Company's obligations hereunder
("Guarantee").

          The Company has heretofore delivered to the Bank unaudited financial
statements, specifically an income statement, balance sheet, and statement of
cash flows, for the period ended December 31, 1997.  There has been no material
adverse change in the business, properties, condition (financial or other) or
operations of the Company since the date of the statements which would adversely
affect the Company's ability to meet its obligations hereunder and under the
Note.

FINANCIAL STATEMENTS

          As long as the Facility is available to the Company or outstandings
exist, the Company shall promptly provide the Bank with annual and quarterly
financial statements of both the Company and Resources on a consolidated basis.
Annual statements shall be supplied within 120 days from the closing of the
respective annual fiscal period and Resources' statements shall be audited by a
nationally recognized independent accountant.  Quarterly financial statements,
prepared in accordance with generally accepted principles and practices of
accounting, shall be supplied within 60 days of the close of each of the first
three quarters of Resources' fiscal year.  The Company will provide the Bank
with any other information the Bank may reasonably request from time to time.

WAIVER OF JURY TRIAL

          Each party hereto hereby waives, to the fullest extent permitted by
applicable law, any right it may have to a trial by jury in any legal proceeding
directly or indirectly arising out of or relating to this agreement or the
transactions contemplated hereby (whether based on contract, tort or any other
theory).  Each party hereto (a) certifies that no representative, agent  or
attorney of any other party has represented, expressly or otherwise, that such
other party would not, in the event of litigation, seek to enforce the foregoing
waiver; and (b) acknowledges that it and the other parties hereto have been
induced to enter into this agreement by, among other things, the mutual waivers
and certifications in this section.

INDEMNIFICATION

          The Company agrees to indemnify the Bank and each of its respective
affiliates, directors, officers and employees (each an "Indemnitee") against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all expenses of litigation or preparation
therefore whether or not the Bank is a party thereto) which any of them may pay
or incur arising out of or relating to the letter agreement, the Note, or any
other agreement executed in connection therewith, the transactions contemplated
hereby, or the direct or indirect application or proposed application of the
proceeds of any Loan hereunder; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee.

Bank shall be in possession of the following:

AGREED TO AND ACCEPTED BY:

FIRST UNION NATIONAL BANK

                       GUARANTEE OF PP&L RESOURCES, INC.
                                        

          In order to induce First Union National Bank (the "Bank") to extend
credit to PP&L Capital Funding, Inc. (the "Company"), under the agreement
between the Bank and the Company dated July 8, 1998 (the "Agreement"), PP&L
Resources, Inc., (Resources) hereby irrevocably and unconditionally guarantees,
as primary obligor and not merely as a surety, the Company's obligations to the
Bank under the Agreement and the Note (as defined in the Agreement), whether for
principal, interest, fees or otherwise (collectively, the "Company
Obligations").  Resources further agrees that the due and punctual payment of
Company Obligations may be extended, in whole or in part, without notice to or
further assent from it, and that it will remain bound upon its Guarantee
hereunder notwithstanding any such extension or renewal of any Company
Obligation.

          Resources waives presentment to, demand of payment from and protest to
the Company of any of the Company Obligations, and also waives notice of
acceptance of its obligations and notice of protest for nonpayment.  The
obligations of Resources hereunder shall not be affected by (a) the failure of
the Bank to assert any claim or demand or to enforce any right or remedy against
the Company under the provisions of this Guarantee, the Agreement, the Note or
otherwise, (b) change or increase in the amount of any of the Company
Obligations, whether or not consented to by Resources, or (c) any rescission,
waiver, amendment or modification of any of the terms or provisions of this
Agreement or any other agreement.

          Resources expressly waives all rights it may now or in the future have
under any statute, or at law or in equity, or otherwise, to compel the Bank to
proceed in respect of the Company obligations against the Company or any other
party or against any security for other guaranty of payment and performance of
the Company obligations before proceeding against, or as a condition to
proceeding against Resources.

          Resources further agrees that its agreement hereunder constitutes a
promise of payment when due (whether or not any bankruptcy or similar proceeding
shall have stayed the accrual or collection of any of the Company Obligations or
operated as a discharge thereof) and not merely of collection, and waives any
right to require that any resort be had by the Bank to any balance of any
deposit account or credit on the books of the Bank in favor of any other person.

          The obligations of Resources hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, and shall not
be subject to any defense or setoff, counterclaim, recoupment or termination
whatsoever, by reason of the invalidity, illegality or unenforceability of the
Company Obligations, any impossibility in the performance of the Company
Obligations or otherwise.  Without limiting the generality of the foregoing, the
obligations of Resources hereunder shall not be discharged or impaired or
otherwise affected by the failure of the Bank to assert any claim or demand or
to enforce any remedy under the Agreement or any other agreement, by any waiver
or modification in respect of any thereof, by any default, failure or delay,
willful or otherwise, in the performance of Company Obligations, or by any other
act or omission which may or might in any manner or to any extent vary the risk
of Resources or otherwise operate as a discharge of Resources or the Company as
a matter of law or equity.

          Resources further agrees that its obligations hereunder shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of any Company Obligation is rescinded or must otherwise be
restored by the Bank upon the bankruptcy or reorganization of the Company or
otherwise.

          In furtherance of the foregoing and not in limitation of any other
right which the Bank may have at law or in equity against Resources by virtue
hereof, upon the 
<PAGE>
 
                                    Page 2

failure of the Company to pay any Company Obligation when and as the same shall
become due, whether at maturity, by acceleration, after notice of prepayment or
otherwise, Resources hereby promises to and will, upon receipt of written demand
by the Bank, forthwith pay, or cause to be paid, in cash the amount of such
unpaid Company Obligations.

          Until such time as the Company Obligations shall have been paid in
full, Resources waives any right of subrogation which it may have in connection
with any payment hereunder; provided, however, that upon payment in full of the
Company Obligations the Bank shall, in reasonable manner, assign to Resources
the amount of such Company Obligations owed to it and so paid, such assignment
to be pro tanto to the extent to which the Company Obligations in question was
      --- -----                                                               
discharged by Resources, or make such disposition thereof as Resources shall
direct (all without recourse to the Bank and without any representation or
warranty by the Bank).

          IN WITNESS WHEREOF, PP&L Resources, Inc. has caused this Guaranty to
be executed this 8th day of July, 1998.

$80,000,000.00                                   July 8, 1998
Commitment of Bank

          PP&L Capital Funding, Inc. (the "Company"), for value received, hereby
promises to pay to the order of First Union National Bank (the "Bank"), for the
account of its appropriate lending office, at its office, One First Union
Center, 5th Floor, 301 South College Street, Charlotte, North Carolina 28288, in
lawful money of the United States, the principal sum of $80,000,000.00, or, if
less, the aggregate unpaid principal amount of all loans made by the Bank to the
Company pursuant to the letter agreement dated July 8, 1998, between the Company
and the Bank (the "Agreement"), on the dates specified for the repayment of such
loans as set forth on the Bank's records or, if not so specified, as provided in
the Agreement.  Each loan evidenced by this Note shall bear interest, payable as
provided in the Agreement.

          The Bank may, at its option, declare this Note immediately due and
payable and terminate its commitment under the Agreement without further
formality, if:

      (a) neither the Company nor PP&L Resources, Inc. ("Resources") pays (x)
          within 5 business days of the due date thereof any interest or fees on
          this Note or under the Agreement, or (y) when due, the principal on
          any loan or any other amount payable hereunder or under the Agreement;

      (b) any representation or warranty by the Company or Resources to the
          Bank in any financial statement, certificate, or other agreement
          proves to have been false or misleading in any material respect when
          made or deemed to have been made;

      (c) the Company or Resources,  as guarantor under a guarantee (the
          "Guarantee") dated the date hereof relating to this Note, shall (i)
          fail to pay any principal or interest, regardless of amount, due in
          respect of any indebtedness in a principal amount in excess of
          $40,000,000, in the case of indebtedness of  Resources or indebtedness
          of the Company guaranteed by Resources or, in the case of indebtedness
          of the Company not guaranteed by Resources, $10,000,000, if such
          failure shall continue beyond any period of grace provided with
          respect thereto, or (ii) fail to observe or perform any other term,
          covenant, condition or agreement contained in any agreement or
          instrument (including any term, covenant, condition or agreement
          herein or in the Agreement) evidencing or governing any such
          indebtedness in a principal amount in excess of, in the case of
          indebtedness of Resources or indebtedness of the Company guaranteed by
          Resources, $40,000,000 or, in the case of indebtedness of the Company
          not guaranteed by Resources, $10,000,000, if such failure shall
          continue beyond any period of grace provided with respect thereto if
          the effect of any failure referred to in this clause (ii) is to cause,
          or to permit the holder or holders of such indebtedness or a trustee
          on its or their

          maturity; or

      (d) the Company or Resources ceases to pay its debts or makes an
          assignment for the benefit of creditors, or any proceeding relating to
          the Company or Resources under any bankruptcy, reorganization,
          arrangement, readjustment of debt, dissolution, or liquidation law or
          statute of any jurisdiction, whether now or hereafter in effect, is
          commenced by or against the Company or Resources or the Company or
          Resources becomes or is adjudicated insolvent or bankrupt, or
          petitions or applies to any tribunal for any receiver of or any
          trustee for the Company or Resources or any substantial part of the
          property of the Company or Resources;

      (e) the ratio of Consolidated Indebtedness of Resources to Consolidated
          Capitalization of Resources exceeds 70% at any time and Resources
          shall have failed to reduce such ratio to 70% or less within 30 days
          after written notice to Resources from the Bank.  For this purpose,
          "Consolidated Indebtedness of Resources" shall mean the Consolidated
          Indebtedness of Resources (determined in accordance with United States
          generally accepted accounting principles (GAAP)), except that for
          purposes of this definition (1) Consolidated Indebtedness of Resources
          shall exclude Non-Recourse Indebtedness of Resources and (2)
          Consolidated Indebtedness of Resources shall exclude any Hybrid
          Preferred Securities of Resources.  Also for this purpose,
          Consolidated Capitalization of Resources shall mean the sum of (A) the
          Consolidated Indebtedness of Resources and (B) (i) the consolidated
          shareowners' equity (determined in accordance with GAAP) of the
          common, preference and preferred stockholders of Resources and (ii)
          the aggregate amount of Hybrid Preferred Securities of Resources,
          except that for purposes of calculating Consolidated Capitalization of
          Resources, Consolidated Indebtedness of Resources shall exclude Non-
          Recourse Indebtedness of Resources and Consolidated Capitalization of
          Resources shall exclude that portion of shareowners' equity
          attributable to assets securing Non-Recourse Indebtedness of
          Resources.  "Hybrid Preferred Securities" of Resources means (1) the
          preferred securities and subordinated debt described in the Prospectus
          dated as of April 3, 1997 of PP&L Capital Trust and PP&L, Inc. and the
          preferred securities and subordinated debt described in the Prospectus
          dated as of June 9, 1997 of PP&L Capital Trust II and PP&L, Inc.
          (collectively, the "Existing TOPrS") and (2) any additional preferred
          securities and subordinated debt (with a maturity of at least twenty
          years) similar to the Existing TOPrS and in an aggregate amount not to

          companies, limited partnerships (or similar entities) (i) all of the
          common equity, general partner or similar interests of which are owned
          (either directly or indirectly through one or more wholly-owned

          been formed for the purpose of

                                    Page 3

          issuing hybrid preferred securities and (iii) substantially all the
          assets of which consist of (A) subordinated debt of Resources or a
          Subsidiary of Resources, as the case may be, and (B) payments made
          from time to time on the subordinated debt. "Indebtedness" of any
          person shall mean, without duplication, (a) all obligations of such
          person for borrowed money, (b) all obligations of such person with
          respect to deposits or advances of any kind, (c) all obligations of
          such person evidenced by bonds, debentures, notes or similar
          instruments, (d) all obligations of such person under conditional sale
          or other title retention agreements relating to property or assets
          purchased by such person, (e) all obligations of such person issued or

          the ordinary course of business), (f) all Indebtedness of others
          secured by (or for which the holder of such Indebtedness has an
          existing right, contingent or otherwise, to be secured by) any Lien or
          property owned or acquired by such person, whether or not the
          obligations secured thereby have been assumed but shall not include
          any obligations that are without recourse to such person, (g) all
          Guarantees by such person of Indebtedness of others, (h) all capital
          lease obligations of such person, (i) all obligations of such person
          in respect of interest rate protection agreements, foreign currency
          exchange agreements or other interest or exchange rate hedging
          arrangements (the amount of any such obligation to be the amount that
          would be payable upon the acceleration, termination or liquidation
          thereof) and (j) all obligations of such person as an account party in
          respect of letters of credit and bankers' acceptances. "Non-Recourse
          Indebtedness of Resources" shall mean indebtedness that is nonrecourse
          to Resources, the Company, PP&L, Inc. ("PP&L") or any of PP&L's
          Subsidiaries; or

      (f) the Guarantee of Resources shall, for any reason, cease to be in full
          force and effect;

provided, that upon the happening of any event specified in subparagraph (d)
above, this Note and any other obligations of the Company to the Bank shall
become immediately due and payable and commitments under the Agreement shall be
terminated without declaration or other notice to the Company.

          If, for any reason (including acceleration), the principal of any
Eurodollar Loan as defined in the Agreement and evidenced by this Note, or any
portion thereof, is paid prior to the last day of an interest period therefore,
the Company shall reimburse the Bank on demand for any resulting loss or expense
incurred by it, including (without limitation) any loss or expense incurred in
obtaining, liquidating or employing deposits from third parties.

          If the Bank reasonably determines at any time that any applicable law,
governmental rule or regulation, or any change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency or compliance by the Bank with any regulatory directive subjects the Bank
to any tax with respect to this Note or payments by the Company of principal or
interest thereunder or hereunder (except for 
<PAGE>
 
                                    Page 4

taxes on or measured by the net income of the Bank), or will have the effect of
increasing the Bank's reserve requirements, deposit requirements, or the amount
of capital required or expected to be maintained by the Bank based on the
existence of the Facility or the Bank's obligations under the Agreement, then
promptly upon receipt of a written demand from the Bank, the Company shall pay
the Bank such additional amounts as shall be required to compensate the Bank for
the increased cost to the Bank as a result of these increases. Each such written
demand shall specify (a) the event pursuant to which the Bank is entitled to
claim the additional amount, (b) the date on which the event occurred and became
applicable to the Bank and (c) the compensation period for which the amount is
due. The period for which the additional amounts may be claimed by the Bank (the
"Compensation Period") shall be the number of days actually elapsed since the
date the event occurred and became applicable to the Bank. Payments made by the
Company to the Bank shall be made on the later of the last day of the
Compensation Period specified in each written demand or 30 days after any such
written demand. Provided that the Bank acts reasonably and in good faith in
determining any additional amounts due, the Bank's determination of compensation
owing shall, absent manifest error, be final, conclusive and binding on the
Company.

          If any loan evidenced by this Note becomes due and payable on a
Saturday, Sunday or public or other banking holiday under the laws of the State
of North Carolina, the maturity thereof shall be extended to the next succeeding
business day, and interest shall be payable thereon at the rate herein specified
during such extension; provided, however, that if any such extension would
result in the interest period for a Eurodollar Loan being carried into another
calendar month, such interest period shall end on the preceding business day.

          If the Bank institutes any action for the enforcement or collection of
this Note, the Company shall pay on demand all costs and expenses of such action
including reasonable legal fees.

          If the unpaid principal amount of any Loan, interest accrued thereon
or any amount owing by the Company hereunder or under the Agreement shall have
become due and payable (by acceleration or otherwise), the Bank shall have the
right, in addition to all other rights and remedies available to it, without
notice to the Company, to set-off against and to appropriate and apply to such
due and payable amounts any debt owing to, and any other funds held in any
manner for the account of, the Company by the Bank including, without
limitation, all funds in all deposit accounts (whether time or demand, general
or special, provisionally credited or finally credited, or otherwise) now or
hereafter maintained by the Company with the Bank.  Such right shall exist
whether or not the Bank shall have given notice or made any demand hereunder,
and regardless of the existence or adequacy of any collateral, guarantee or any
other security, right or remedy available to the Bank.  Nothing herein or in the
Agreement shall be deemed a waiver or prohibition of or restriction on the
Bank's rights of banker's lien or set-off.  Presentment for payment, notice of
dishonor, protest and notice of protest are hereby waived.
