      WHEREAS, PCH has incurred Debt (as hereinafter defined), and intends to
incur Debt from time to time from parties other than Progress to enable PCH to

      WHEREAS, Progress and PCH desire to enter into this Agreement for the

            d.  "Guarantee" means the liability of PCH under any agreement by

such case, the liability of PCH to be reasonably capable of being calculated, 
and shall include, without limitation, the contingent liability of PCH under any

members of the Board of Directors of PCH (except for any shares of PCH's stock
having the special right to vote for directors in circumstances involving PCH's
default in the payment of dividends or sinking funds), and will not pledge,
encumber or dispose of any of such shares unless required to do so pursuant to a
court order or decree of any governmental authority which, in the opinion of
counsel to Progress, may not be successfully challenged.

      3.  Guaranty.

            a.  Subject to the provisions of paragraph 4 below, Progress hereby
unconditionally guarantees to each Holder of any Debt that:  (i) in the event of
the nonpayment by PCH, when due, of the full amount of (a) any Debt stated in
any Operative Instrument to be payable by PCH, and (b) all other amounts payable
by PCH pursuant to any Operative Instrument in respect of any Debt, including,
without limitation, the principal of, the interest and any premium on, the Debt
and including any such amount payable pursuant to any waiver, modification,
amendment or change of any provision of any of the Operative Instruments in
accordance with the terms of the applicable waiver, modification, amendment or
change, Progress will promptly pay in full such amount when due in accordance
with the provisions of the applicable Operative Instrument, whether at maturity,
or as a prepayment or by acceleration or otherwise, all at the time and place
and in the amount and manner prescribed in, and otherwise in accordance with,
the applicable Operative Instrument, and (ii) Progress will, promptly after
demand, pay to each Holder of any Debt the costs and expenses incurred in
connection with enforcing the rights of such Holder against PCH by reason of
PCH's failure to pay, or against Progress by reason of Progress' failure to pay,
in accordance with this paragraph 3, including, without limitation, the
reasonable fees and expenses of counsel and including the reasonable fees and
expenses incurred in any insolvency or bankruptcy case or proceeding. 

            b.  This is an unconditional and absolute guaranty of payment and
not a guaranty of collection.  If for any reason PCH fails to pay, when due and
in the full amount, 

                                     2


any amount referred to in paragraph 3.a. hereof, Progress will pay such amount, 
in full, to the Person entitled to receive the same, regardless of any defense 
or set-off or counterclaim which PCH or any other Person may have or assert and 
regardless of whether or not the Holder of any Debt or anyone acting on behalf 
of such Holder shall have instituted any suit, action or proceeding or exhausted
its remedies or taken any steps to enforce any rights against PCH or any other 
Person to compel any such payment or to collect all or part of any such amount, 
either pursuant to the provisions of any Operative Instrument or at law or in 
equity, and regardless of any other condition or contingency.

            c.  Progress hereby unconditionally:  (i) waives any requirement
that, in the event of any default by PCH in the payment, when due, of the full
amount payable in respect of any Debt of PCH, the Holder of any such Debt first
make demand upon, or seek to enforce remedies against, PCH or any other Person
before demanding payment under or seeking to enforce such Holder's rights under
this Agreement; (ii) covenants that such Holder's rights under this Agreement
will not be discharged except by complete performance of all payment obligations
of PCH in respect of Debt contained in every Operative Instrument or as
otherwise expressly agreed to in writing by each Holder of the Debt; (iii)
agrees that such Holder's rights under this Agreement shall remain in full force
and effect without regard to, and shall not be affected or impaired, without
limitation, by, any invalidity, irregularity or unenforceability in whole or in
part of any Debt of PCH or any Operative Instrument or any limitation on the
liability of PCH thereunder, or any impossibility or illegality of performance
on the part of PCH under any Debt of PCH or any of the Operative Instruments or
any limitation on the method or terms of payment thereunder which may now or
hereafter be caused or imposed in any manner whatsoever; and (iv) waives
diligence, presentment and protest with respect to, and any notice of default in
the payment of any amount at any time payable by PCH under or in connection
with, any Debt of PCH or any Operative Instrument.  

           d.  The obligations, covenants, agreements and duties of Progress 
under this paragraph 3 shall not be released, affected or impaired by any 
assignment or transfer, in whole or in part, of any Debt or Operative 
Instrument, although made without notice to or the consent of Progress, or any 
waiver by the Holder of any Debt, or by any other Person, of the performance or 
observance by PCH or Progress of any of the agreements, covenants, terms or 
conditions contained in any Operative Instrument, or any indulgence in or the 
extension of time for payment by PCH or renewal thereof, or the modification or 
amendment (whether material or otherwise) of any duty, agreement or obligation 
of PCH or any guaranty set forth in any Operative Instrument, or the voluntary 
or involuntary liquidation, administration, sale or other disposition of all or 
substantially all of the assets of PCH or Progress, or any receivership, 
insolvency, bankruptcy, reorganization, or other similar proceeding, affecting 
PCH or Progress or any assets of PCH or Progress, or the release of any property
from any security for any Debt, or the impairment of any such property or 
security, or the release or discharge of PCH or Progress from the performance or
observance of any agreement, covenant, term or condition contained in any
Operative Instrument by operation of law, or the merger or consolidation of PCH
or Progress, or any other cause, whether similar or dissimilar to the foregoing.
Progress agrees that no Holder of any Debt shall be under any obligations to
marshall any assets in favor 

                                      3


of Progress or otherwise in connection with obtaining payment of any or all of 
the obligations under the Operative Instruments from any Person or source.

            e.  If Progress shall be required to make any payments on account
of any Debt or otherwise in accordance with any Operative Instruments and
pursuant to this paragraph 3, Progress shall be subrogated to the rights of the
Holder of such Debt (subject to the prior payment in full in cash of all
principal, interest and premium, if any, due on all the Debt and all amounts
payable under any Operative Instrument on account of Debt) to receive payments
or distributions of assets of PCH payable or distributable to such Holder until
Progress shall have been repaid in full.

            f.  If at any time any payment received by any Holder of any Debt
under any Operative Instrument is required to be repaid by such Holder, the
obligations, covenants, agreements and duties of Progress under this paragraph 3
shall be reinstated as if such payment had not been made.

            g.  The obligations of Progress under this paragraph 3 are
continuing obligations and a separate cause of action shall arise in respect of
each default hereunder.  No failure on the part of the Holder of any Debt 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 right hereunder
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 or any of the Operative Instruments.  This paragraph 3
constitutes a continuing guaranty and shall (i) remain in full force and effect
until indefeasible payment in full of all the payment obligations under the
Operative Instruments and all other amounts payable under this paragraph 3, (ii)
be binding upon Progress, its successors and assigns, including, without
limitation, a receiver, trustee or debtor-in-possession of or for Progress, and
(iii) inure to the benefit of and be enforceable by each Holder of any Debt and
its respective successors, transferees and assigns.  Without limiting the
generality of the foregoing clause (iii), the Holder of any Debt may assign or
otherwise transfer any Debt to any other Person, and such other Person shall
thereupon become vested with all the rights in respect thereof granted to such
Holder therein or otherwise with respect to such Debt so transferred or
assigned.
 
      4.  Rights of Holders.  Notwithstanding the foregoing, in no event may any
Holder of any Debt, on default by Progress or PCH or upon failure to comply with
this Agreement by Progress, have recourse to or against the stock of Florida
Power Corporation held by Progress, the assets of Florida Power Corporation or
any interest of Progress or PCH in such stock or assets.  
 
      5.  Amendments and Termination.  This Agreement may be amended or modified
at any time by the parties hereto; provided, however, that no such amendment or
modification which adversely affects the Holders of Debt outstanding at the time
of execution thereof shall be binding on or in any manner become effective with
respect to such Debt except with the prior written consent of the Holders of not
less than a majority in principal amount of Debt at the time 

                                     4


outstanding.  This Agreement may be terminated by either party hereto upon 30 
days prior written notice to the other party; provided, however, that this 
Agreement shall not terminate until such time as all Debt outstanding on or 
prior to the date of the giving of notice of termination shall have been paid.  
Notwithstanding the foregoing, the parties hereto may not modify or terminate 
any or all of the provisions of this Agreement with respect to any Debt then 
outstanding unless two nationally recognized rating organizations confirm in 
writing that their rating for such Debt would be the same whether or not such 
provisions were in effect.

      6.  Successors.  This Agreement shall be binding upon the parties hereto
and their respective successors and assigns and is also intended for the benefit
of the Holders from time to time of the Debt and, notwithstanding that such
Holders are not parties hereto, each such Holder shall be entitled to the full
benefits of this Agreement and to enforce the covenants and agreements contained
herein.  This Agreement is not intended for the benefit of any person other than
the Holders of the Debt, and shall not confer or be deemed to confer upon any
other such person any benefits, rights or remedies hereunder.

      7.  Governing Law.  This Agreement shall be governed by the laws of the
State of Florida.

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed and delivered by their respective officers thereunto duly authorized as
of the day and year first above written.
