Corporation, a Delaware corporation (the "Guarantor"), and Wilmington Trust
Company, as trustee (the "Preferred Guarantee Trustee"), for the benefit of the
Holders (as defined herein) from time to time of the Preferred Securities (as
defined herein) of PLC Capital Trust IV, a Delaware statutory business trust
(the "Issuer").

          WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of September 25, 2002, among the trustees of the Issuer
named therein, the Guarantor, as sponsor, and the holders from time to time of
undivided beneficial interests in the assets of the Issuer, the Issuer is
issuing on the date hereof 4,600,000 preferred securities, having an aggregate
liquidation amount of $115,000,000, designated the 7-1/4% Trust Originated
Preferred Securities (the "Preferred Securities") and 142,280 common securities,
having an aggregate liquidation amount of $3,557,000, designated the 7-1/4%
Trust Originated Common Securities (the "Common Securities");

          WHEREAS, as incentive for the Holders to purchase the Preferred
Securities, the Guarantor desires irrevocably and unconditionally to agree, to

and to make certain other payments on the terms and conditions set forth herein;
and

          WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "Common Securities Guarantee") in substantially identical terms
to this Preferred Securities Guarantee for the benefit of the holders of the
Common Securities (as defined herein), except that if an Event of Default (as
defined in the Indenture), has occurred and is continuing, the rights of holders
of the Common Securities to receive Guarantee Payments under the Common
Securities Guarantee are subordinated to the rights of Holders of Preferred
Securities to receive Guarantee Payments under this Preferred Securities
Guarantee.

          NOW, THEREFORE, in consideration of the purchase by each Holder of
Preferred Securities, which purchase the Guarantor hereby agrees shall benefit
the Guarantor, the Guarantor executes and delivers this Preferred Securities
Guarantee for the benefit of the Holders.

                           PREFERRED GUARANTEE TRUSTEE

          SECTION 3.1. POWERS AND DUTIES OF THE PREFERRED GUARANTEE TRUSTEE. (a)
This Preferred Securities Guarantee shall be held by the Preferred Guarantee
Trustee for the benefit of the Holders of the Preferred Securities, and the
Preferred Guarantee Trustee shall not transfer this Preferred Securities
Guarantee to any Person except a Holder of Preferred Securities exercising his
or her rights pursuant to Section 5.4(b) or to a Successor Preferred Guarantee
Trustee on acceptance by such Successor Preferred Guarantee Trustee of its
appointment to act as Successor Preferred Guarantee Trustee. The right, title
and interest of the Preferred Guarantee Trustee shall automatically vest in any
Successor Preferred Guarantee Trustee, and such vesting and cessation of title
shall be effective whether or not conveyancing documents have been executed and
delivered pursuant to the appointment of such Successor Preferred Guarantee
Trustee.

          (b) If an Event of Default actually known to a Responsible Officer of
the Preferred Guarantee Trustee has occurred and is continuing, the Preferred
Guarantee Trustee shall enforce this Preferred Securities Guarantee for the
benefit of the Holders of the Preferred Securities.

          (c) The Preferred Guarantee Trustee, before the occurrence of any
Event of Default and after the curing of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Preferred Securities Guarantee, and no implied covenants shall be
read into this Preferred Securities Guarantee against the Preferred Guarantee
Trustee. In case an Event of Default has occurred (that has not been cured or
waived pursuant to Section 2.6) and is actually known to a Responsible Officer
of the Preferred Guarantee Trustee, the Preferred Guarantee Trustee shall
exercise such of the rights and powers vested in it by this Preferred Securities
Guarantee, and use the same degree of care and skill in its exercise thereof, as
a prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

          (d) No provision of this Preferred Securities Guarantee shall be
construed to relieve the Preferred Guarantee Trustee from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                  (i) prior to the occurrence of any Event of Default and after
         the curing or waiving of all such Events of Default that may have
         occurred:

                           (A) the duties and obligations of the Preferred
                  Guarantee Trustee shall be determined solely by the express
                  provisions of this Preferred Securities Guarantee, and the
                  Preferred Guarantee Trustee shall not be liable except for the
                  performance of such duties and obligations as are specifically
                  set forth in this Preferred Securities

                                       6

<Page>

                  Guarantee, and no implied covenants or obligations shall be
                  read into this Preferred Securities Guarantee against the
                  Preferred Guarantee Trustee; and

                           (B) in the absence of bad faith on the part of the
                  Preferred Guarantee Trustee, the Preferred Guarantee Trustee
                  may conclusively rely, as to the truth of the statements and
                  the correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Preferred Guarantee
                  Trustee and conforming to the requirements of this Preferred
                  Securities Guarantee; but in the case of any such certificates
                  or opinions that by any provision hereof are specifically
                  required to be furnished to the Preferred Guarantee Trustee,
                  the Preferred Guarantee Trustee shall be under a duty to
                  examine the same to determine whether or not they conform to
                  the requirements of this Preferred Securities Guarantee;

                  (ii) the Preferred Guarantee Trustee shall not be liable for
         any error of judgment made in good faith by a Responsible Officer of
         the Preferred Guarantee Trustee, unless it shall be proved that the
         Preferred Guarantee Trustee was negligent in ascertaining the pertinent
         facts upon which such judgment was made;

                  (iii) the Preferred Guarantee Trustee shall not be liable with
         respect to any action taken or omitted to be taken by it in good faith
         in accordance with the direction of the Holders of not less than a
         Majority in liquidation amount of the Preferred Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Guarantee Trustee, or exercising any trust
         or power conferred upon the Preferred Guarantee Trustee under this
         Preferred Securities Guarantee; and

                  (iv) no provision of this Preferred Securities Guarantee shall
         require the Preferred Guarantee Trustee to expend or risk its own funds
         or otherwise incur personal financial liability in the performance of
         any of its duties or in the exercise of any of its rights or powers, if
         the Preferred Guarantee Trustee shall have reasonable grounds for
         believing that the repayment of such funds or liability is not
         reasonably assured to it under the terms of this Preferred Securities
         Guarantee or indemnity, reasonably satisfactory to the Preferred
         Guarantee Trustee, against such risk or liability is not reasonably
         assured to it.

Subject to the provisions of Section 3.1:

                  (i) The Preferred Guarantee Trustee may conclusively rely, and

         proper party or parties.

                  (iii) Whenever, in the administration of this Preferred
         Securities Guarantee, the Preferred Guarantee Trustee shall deem it
         desirable that a matter be proved or established before taking,
         suffering or omitting any action hereunder, the Preferred Guarantee
         Trustee (unless other evidence is herein specifically prescribed) may,
         in the absence of bad faith on its part, request and conclusively rely

         shall be promptly delivered by the Guarantor.

                  (iv) The Preferred Guarantee Trustee shall have no duty to see

         rerecording, refiling or registration thereof).

                  (v) The Preferred Guarantee Trustee may consult with counsel,
         and the written advice or opinion of such counsel with respect to legal
         matters shall be full and complete authorization and protection in
         respect of any action taken, suffered or omitted by it hereunder in
         good faith and in accordance with such advice or opinion. Such counsel
         may be counsel to the Guarantor or any of its Affiliates and may
         include any of its employees. The Preferred Guarantee Trustee shall
         have the right at any time to seek instructions concerning the
         administration of this Preferred Securities Guarantee from any court of
         competent jurisdiction.

                  (vi) The Preferred Guarantee Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by this
         Preferred Securities Guarantee at the request or direction of any
         Holder, unless such Holder shall have provided to the Preferred
         Guarantee Trustee such security and indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses and the expenses of the
         Preferred Guarantee Trustee's agents, nominees or custodians) and
         liabilities that might be incurred by it in complying with such request
         or direction, including such reasonable advances as may be requested by
         the Preferred Guarantee Trustee; provided that, nothing contained in
         this Section 3.2(a)(vi) shall be taken to relieve the Preferred
         Guarantee Trustee, upon the occurrence of an Event of Default, of its
         obligation to exercise the rights and powers vested in it by this
         Preferred Securities Guarantee.

                  (vii) The Preferred Guarantee Trustee shall not be bound to
         make any investigation into the facts or matters stated in any
         resolution, certificate, statement, instrument, opinion, report,
         notice, request, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document, but the
         Preferred Guarantee Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit.

                  (viii) The Preferred Guarantee Trustee may execute any of the
         trusts or powers hereunder or perform any duties hereunder either
         directly or by or through agents, nominees, custodians or attorneys,
         and the Preferred Guarantee Trustee shall not be responsible for any

                                       8

<Page>

         misconduct or negligence on the part of any agent or attorney appointed
         with due care by it hereunder.

                  (ix) Any action taken by the Preferred Guarantee Trustee or
         its agents hereunder shall bind the Holders of the Preferred
         Securities, and the signature of the Preferred Guarantee Trustee or its
         agents alone shall be sufficient and effective to perform any such
         action. No third party shall be required to inquire as to the authority
         of the Preferred Guarantee Trustee to so act or as to its compliance
         with any of the terms and provisions of this Preferred Securities
         Guarantee, both of which shall be conclusively evidenced by the
         Preferred Guarantee Trustee's or its agent's taking such action.

                  (x) Whenever in the administration of this Preferred
         Securities Guarantee the Preferred Guarantee Trustee shall deem it
         desirable to receive instructions with respect to enforcing any remedy
         or right or taking any other action hereunder, the Preferred Guarantee
         Trustee (i) may request instructions from the Holders of a Majority in
         liquidation amount of the Preferred Securities, (ii) may refrain from
         enforcing such remedy or right or taking such other action until such
         instructions are received, and (iii) shall be protected in conclusively
         relying on or acting in accordance with such instructions.

          (b) No provision of this Preferred Securities Guarantee shall be
deemed to impose any duty or obligation on the Preferred Guarantee Trustee to
perform any act or acts or exercise any right, power, duty or obligation
conferred or imposed on it in any jurisdiction in which it shall be illegal, or
in which the Preferred Guarantee Trustee shall be unqualified or incompetent in
accordance with applicable law, to perform any such act or acts or to exercise
any such right, power, duty or obligation. No permissive power or authority
available to the Preferred Guarantee Trustee shall be construed to be a duty.

          SECTION 3.3. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE.
The recitals contained in this Guarantee shall be taken as the statements of the
Guarantor, and the Preferred Guarantee Trustee does not assume any
responsibility for their correctness. The Preferred Guarantee Trustee makes no
representation as to the validity or sufficiency of this Preferred Securities
Guarantee.

         powers, having a combined capital and surplus of at least 50 million
         U.S. dollars ($50,000,000), and subject to supervision or examination
         by Federal, State, Territorial or District of Columbia authority. If
         such corporation publishes reports of condition at least annually,
         pursuant to law or to the requirements of the supervising or examining
         authority referred to above, then, for the purposes of this Section
         4.1(a)(ii), the combined capital and surplus of such corporation shall
         be deemed to be its combined capital and surplus as set forth in its
         most recent report of condition so published.

          (b) If at any time the Preferred Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Preferred Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section 4.2 (c).

Trustee may be appointed or removed without cause at any time by the Guarantor.

          (b) The Preferred Guarantee Trustee shall not be removed in accordance
with Section 4.2(a) until a Successor Preferred Guarantee Trustee has been
appointed and has accepted such appointment by written instrument executed by
such Successor Preferred Guarantee Trustee and delivered to the Guarantor.

          (c) The Preferred Guarantee Trustee appointed to office shall hold
office until a Successor Preferred Guarantee Trustee shall have been appointed
or until its removal or resignation. The Preferred Guarantee Trustee may resign
from office (without need for prior or subsequent accounting) by an instrument
in writing executed by the Preferred Guarantee Trustee and delivered to the
Guarantor, which resignation shall not take effect until a Successor Preferred
Guarantee Trustee has been appointed and has accepted such appointment by
instrument in writing executed by such Successor Preferred Guarantee Trustee and
delivered to the Guarantor and the resigning Preferred Guarantee Trustee.

          (d) If no Successor Preferred Guarantee Trustee shall have been

resigning Preferred Guarantee Trustee may petition any court of competent
jurisdiction for appointment of a Successor Preferred Guarantee Trustee. Such

defense, right of set-off or counterclaim that the Issuer may have or assert.
The Guarantor's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

          SECTION 5.2. WAIVER OF NOTICE AND DEMAND. The Guarantor hereby waives
notice of acceptance of this Preferred Securities Guarantee and of any liability

dishonor, notice of redemption and all other notices and demands.

          SECTION 5.3. OBLIGATIONS NOT AFFECTED. The obligations, covenants,

connection with, the Preferred Securities (other than an extension of time for

sum payable that results from the extension of any interest payment period on
the Debentures or any extension of the maturity date of the Debentures permitted

any action on the part of the Issuer granting indulgence or extension of any
kind;

Securities;

          (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

          (g) any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

          There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

          SECTION 5.4. RIGHTS OF HOLDERS. (a) The Holders of a Majority in
liquidation amount of the Preferred Securities have the right to direct the
time, method and place of conducting of any proceeding for any remedy available
to the Preferred Guarantee Trustee in respect of this Preferred Securities
Guarantee or exercising any trust or power conferred upon the Preferred
Guarantee Trustee under this Preferred Securities Guarantee.

          (b) If the Preferred Guarantee Trustee fails to enforce this Preferred
Securities Guarantee with respect to the right of any Holders to receive any
Guarantee Payment in accordance herewith, such Holder may directly institute a
proceeding against the Guarantor for enforcement of the Preferred Security
Guarantee for such payment. The Guarantor waives any right or remedy to require
that any action be brought first against the Issuer or any other Person or
entity before proceeding directly against the Guarantor.

the extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under this
Preferred Securities Guarantee, if, at the time of any such payment, any amounts
are due and unpaid under this Preferred Securities Guarantee. If any amount
shall be paid to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Preferred Securities Guarantee notwithstanding the occurrence of
any event referred to in subsections (a) through (g), inclusive, of Section 5.3

          SECTION 3.1. POWERS AND DUTIES OF THE COMMON GUARANTEE TRUSTEE. (a)
This Common Securities Guarantee shall be held by the Common Guarantee Trustee
for the benefit of the Holders of the Common Securities, and the Common

Person except a Holder of Common Securities exercising his or her rights
pursuant to Section 5.4(b) or to a Successor Common Guarantee Trustee on
acceptance by such Successor Common Guarantee Trustee of its appointment to act
as Successor Common Guarantee Trustee. The right, title and interest of the
Common Guarantee Trustee shall automatically vest in any Successor Common
Guarantee Trustee, and such vesting and cessation of title shall be effective
whether or not conveyancing documents have been executed and delivered pursuant
to the appointment of such Successor Common Guarantee Trustee.

          (b) If an Event of Default actually known to a Responsible Officer of
the Common Guarantee Trustee has occurred and is continuing, the Common
Guarantee Trustee shall enforce this Common Securities Guarantee for the benefit
of the Holders of the Common Securities.

          (c) The Common Guarantee Trustee, before the occurrence of any Event
of Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Common Securities Guarantee, and no implied covenants shall be read into
this Common Securities Guarantee against the Common Guarantee Trustee. In case
an Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6) and is actually known to a Responsible Officer of the Common
Guarantee Trustee, the Common Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Common Securities Guarantee, and use the
same degree of care and skill in its exercise thereof, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

                                       6

<Page>

          (d) No provision of this Common Securities Guarantee shall be
construed to relieve the Common Guarantee Trustee from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                  (i) prior to the occurrence of any Event of Default and after
         the curing or waiving of all such Events of Default that may have
         occurred:

                           (A) the duties and obligations of the Common
                  Guarantee Trustee shall be determined solely by the express
                  provisions of this Common Securities Guarantee, and the Common
                  Guarantee Trustee shall not be liable except for the
                  performance of such duties and obligations as are specifically
                  set forth in this Common Securities Guarantee, and no implied
                  covenants or obligations shall be read into this Common
                  Securities Guarantee against the Common Guarantee Trustee; and

                           (B) in the absence of bad faith on the part of the
                  Common Guarantee Trustee, the Common Guarantee Trustee may
                  conclusively rely, as to the truth of the statements and the
                  correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Common Guarantee
                  Trustee and conforming to the requirements of this Common
                  Securities Guarantee; but in the case of any such certificates
                  or opinions that by any provision hereof are specifically
                  required to be furnished to the Common Guarantee Trustee, the
                  Common Guarantee Trustee shall be under a duty to examine the
                  same to determine whether or not they conform to the
                  requirements of this Common Securities Guarantee;

                  (ii) the Common Guarantee Trustee shall not be liable for any
         error of judgment made in good faith by a Responsible Officer of the
         Common Guarantee Trustee, unless it shall be proved that the Common
         Guarantee Trustee was negligent in ascertaining the pertinent facts
         upon which such judgment was made;

                  (iii) the Common Guarantee Trustee shall not be liable with
         respect to any action taken or omitted to be taken by it in good faith
         in accordance with the direction of the Holders of not less than a
         Majority in liquidation amount of the Common Securities relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the Common Guarantee Trustee, or exercising any trust or
         power conferred upon the Common Guarantee Trustee under this Common
         Securities Guarantee; and

                  (iv) no provision of this Common Securities Guarantee shall
         require the Common Guarantee Trustee to expend or risk its own funds or
         otherwise incur personal financial liability in the performance of any
         of its duties or in the exercise of any of its rights or powers, if the
         Common Guarantee Trustee shall have reasonable grounds for believing
         that the repayment of such funds or liability is not reasonably assured
         to it under the terms of this Common Securities Guarantee or indemnity,
         reasonably satisfactory to the Common Guarantee Trustee, against such
         risk or liability is not reasonably assured to it.

         Direction (as defined in the Declaration) or an Officers' Certificate.

                  (iii) Whenever, in the administration of this Common
         Securities Guarantee, the Common Guarantee Trustee shall deem it
         desirable that a matter be proved or established before taking,
         suffering or omitting any action hereunder, the Common Guarantee
         Trustee (unless other evidence is herein specifically prescribed) may,
         in the absence of bad faith on its part, request and conclusively rely
         upon an Officers' Certificate which, upon receipt of such request,
         shall be promptly delivered by the Guarantor.

                  (iv) The Common Guarantee Trustee shall have no duty to see to
         any recording, filing or registration of any instrument (or any
         rerecording, refiling or registration thereof).

                  (v) The Common Guarantee Trustee may consult with counsel, and
         the written advice or opinion of such counsel with respect to legal
         matters shall be full and complete authorization and protection in
         respect of any action taken, suffered or omitted by it hereunder in
         good faith and in accordance with such advice or opinion. Such counsel
         may be counsel to the Guarantor or any of its Affiliates and may
         include any of its employees. The Common Guarantee Trustee shall have
         the right at any time to seek instructions concerning the
         administration of this Common Securities Guarantee from any court of
         competent jurisdiction.

                  (vi) The Common Guarantee Trustee shall be under no obligation
         to exercise any of the rights or powers vested in it by this Common
         Securities Guarantee at the request or direction of any Holder, unless
         such Holder shall have provided to the Common Guarantee Trustee such
         security and indemnity, reasonably satisfactory to the Common Guarantee
         Trustee, against the costs, expenses (including attorneys' fees and
         expenses and the expenses of the Common Guarantee Trustee's agents,
         nominees or custodians) and liabilities that might be incurred by it in
         complying with such request or direction, including such reasonable
         advances as may be requested by the Common Guarantee Trustee; provided
         that, nothing contained in this Section 3.2(a)(vi) shall be taken to
         relieve the Common Guarantee

                                       8

         Trustee, upon the occurrence of an Event of Default, of its obligation
         to exercise the rights and powers vested in it by this Common
         Securities Guarantee.

                  (vii) The Common Guarantee Trustee shall not be bound to make
         any investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Common Guarantee
         Trustee, in its discretion, may make such further inquiry or
         investigation into such facts or matters as it may see fit.

                  (viii) The Common Guarantee Trustee may execute any of the
         trusts or powers hereunder or perform any duties hereunder either
         directly or by or through agents, nominees, custodians or attorneys,
         and the Common Guarantee Trustee shall not be responsible for any
         misconduct or negligence on the part of any agent or attorney appointed
         with due care by it hereunder.

                  (ix) Any action taken by the Common Guarantee Trustee or its
         agents hereunder shall bind the Holders of the Common Securities, and
         the signature of the Common Guarantee Trustee or its agents alone shall
         be sufficient and effective to perform any such action. No third party
         shall be required to inquire as to the authority of the Common
         Guarantee Trustee to so act or as to its compliance with any of the
         terms and provisions of this Common Securities Guarantee, both of which
         shall be conclusively evidenced by the Common Guarantee Trustee's or
         its agent's taking such action.

                  (x) Whenever in the administration of this Common Securities
         Guarantee the Common Guarantee Trustee shall deem it desirable to
         receive instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Common Guarantee Trustee (i) may
         request instructions from the Holders of a Majority in liquidation
         amount of the Common Securities, (ii) may refrain from enforcing such
         remedy or right or taking such other action until such instructions are
         received, and (iii) shall be protected in conclusively relying on or
         acting in accordance with such instructions.

          (b) No provision of this Common Securities Guarantee shall be deemed
to impose any duty or obligation on the Common Guarantee Trustee to perform any
act or acts or exercise any right, power, duty or obligation conferred or
imposed on it in any jurisdiction in which it shall be illegal, or in which the
Common Guarantee Trustee shall be unqualified or incompetent in accordance with
applicable law, to perform any such act or acts or to exercise any such right,
power, duty or obligation. No permissive power or authority available to the
Common Guarantee Trustee shall be construed to be a duty.

          SECTION 3.3. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE.
The recitals contained in this Guarantee shall be taken as the statements of the
Guarantor, and the Common Guarantee Trustee does not assume any responsibility
for their correctness. The Common Guarantee

                  (i)  not be an Affiliate of the Guarantor; and

         trustee under the Trust Indenture Act, authorized under such laws to
         exercise corporate trust powers, having a combined capital and surplus
         of at least 50 million U.S. dollars ($50,000,000), and subject to
         supervision or examination by Federal, State, Territorial or District
         of Columbia authority. If such corporation publishes reports of
         condition at least annually, pursuant to law or to the requirements of
         the supervising or examining authority referred to above, then, for the
         purposes of this Section 4.1(a)(ii), the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

          (b) If at any time the Common Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Common Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section 4.2 (c).

          (c) If the Common Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Common Guarantee Trustee and Guarantor shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act.

          SECTION 4.2. APPOINTMENT, REMOVAL AND RESIGNATION OF COMMON GUARANTEE

appointed or removed without cause at any time by the Guarantor.

          (b) The Common Guarantee Trustee shall not be removed in accordance

          (c) The Common Guarantee Trustee appointed to office shall hold office
until a Successor Common Guarantee Trustee shall have been appointed or until
its removal or resignation. The Common Guarantee Trustee may resign from office
(without need for prior or subsequent accounting) by an instrument in writing
executed by the Common Guarantee Trustee and delivered to the Guarantor, which
resignation shall not take effect until a Successor Common Guarantee Trustee has
been appointed and has accepted such appointment by instrument in writing
executed by such Successor Common Guarantee Trustee and delivered to the
Guarantor and the resigning Common Guarantee Trustee.

          (d) If no Successor Common Guarantee Trustee shall have been appointed
and accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning Common
Guarantee Trustee may petition any court of competent jurisdiction for
appointment of a Successor Common Guarantee Trustee. Such court may thereupon,
after prescribing such notice, if any, as it may deem proper, appoint a
Successor Common Guarantee Trustee.

          (e) No Common Guarantee Trustee shall be liable for the acts or
omissions to act of any Successor Common Guarantee Trustee.

          (f) Upon termination of this Common Securities Guarantee or removal or
resignation of the Common Guarantee Trustee pursuant to this Section 4.2, the
Guarantor shall pay to the Common Guarantee Trustee all amounts accrued to the
date of such termination, removal or resignation.

                                    GUARANTEE

          SECTION 5.1. GUARANTEE. The Guarantor irrevocably and unconditionally
agrees to pay in full to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by the Issuer), as and when due, regardless of any
defense, right of set-off or counterclaim that the Issuer may have or assert.
The Guarantor's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

          SECTION 5.2. WAIVER OF NOTICE AND DEMAND. The Guarantor hereby waives
notice of acceptance of this Common Securities Guarantee and of any liability to
which it applies or may apply, presentment, demand for payment, any right to
require a proceeding first against the Issuer or any other Person before
proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.

          SECTION 5.3. OBLIGATIONS NOT AFFECTED. The obligations, covenants,
agreements and duties of the Guarantor under this Common Securities Guarantee
shall in no way be affected or impaired by reason of the happening from time to
time of any of the following:

observed by the Issuer;

          (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Common Securities or the extension of
time for the performance of any other obligation under, arising out of, or in
connection with, the Common Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sum payable that results from the extension of any interest payment period on
the Debentures or any extension of the maturity date of the Debentures permitted
by the Indenture);

          (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Common Securities, or any
action on the part of the Issuer granting indulgence or extension of any kind;

          (d) the voluntary or involuntary liquidation, dissolution, sale of any

          (e) any invalidity of, or defect or deficiency in, the Common
Securities;

          (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

          (g) any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

          There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

          SECTION 5.4. RIGHTS OF HOLDERS. (a) The Holders of a Majority in
liquidation amount of the Common Securities have the right to direct the time,
method and place of conducting of any proceeding for any remedy available to the
Common Guarantee Trustee in respect of this Common Securities Guarantee or
exercising any trust or power conferred upon the Common Guarantee Trustee under
this Common Securities Guarantee.

          (b) If the Common Guarantee Trustee fails to enforce this Common
Securities Guarantee with respect to the right of any Holders to receive any
Guarantee Payment in accordance herewith,

                                       12

<Page>

such Holder may directly institute a proceeding against the Guarantor for
enforcement of the Common Security Guarantee for such payment. The Guarantor
waves any right or remedy to require that any action be brought first against
the Issuer or any other Person or entity before proceeding directly against the
Guarantor.

any amounts paid to such Holders by the Guarantor under this Common Securities
Guarantee; provided, however, that the Guarantor shall not (except to the extent
required by mandatory provisions of law) be entitled to enforce or exercise any
right that it may acquire by way of subrogation or any indemnity, reimbursement
or other agreement, in all cases as a result of payment under this Common
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Common Securities Guarantee. If any amount shall be paid
to the Guarantor in violation of the preceding sentence, the Guarantor agrees to
hold such amount in trust for the Holders and to pay over such amount to the
Holders.

          SECTION 5.7. INDEPENDENT OBLIGATIONS. The Guarantor acknowledges that
its obligations hereunder are independent of the obligations of the Issuer with
respect to the Common Securities, and that the Guarantor shall be liable as
principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Common Securities Guarantee notwithstanding the occurrence of any
event referred to in subsections (a) through (g), inclusive, of Section 5.3
hereof.

                                   ARTICLE VI.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

          SECTION 6.1. LIMITATION OF TRANSACTIONS. So long as any Common

pursuant to an acquisition, the conversion or exchange provisions of such

Preferred Securities Guarantee, dated as of September 25, 2002 of the Guarantor
with respect to the 7-1/4% Trust Originated Preferred Securities, this
Agreement, the Preferred Securities Guarantee, dated as of April 29, 1997 and

an unsecured obligation of the Guarantor and will rank (i) subordinate and
junior in right of payment to all Senior Indebtedness as such term is defined in

Securities Guarantee of PLC Capital Trust's 7-1/4% Trust Originated Preferred

PASSU by their terms and (iii) senior to the Guarantor's common stock, the most
senior preferred or preference stock now or hereafter issued by the Guarantor
and with any guarantee now or hereafter entered into by the Guarantor in respect
of any preferred or preference stock of any affiliate of the Guarantor.

          If an Event of Default has occurred and is continuing under the
Declaration, the rights of the Holders of the Common Securities to receive
Guarantee Payments under this Common Securities Guarantee shall be subordinated
to the rights of the holders of the Preferred Securities to receive payment of
all amounts due and owing under the terms of the Preferred Securities Guarantee.

                                  ARTICLE VII.

          SECTION 7.1. TERMINATION. This Common Securities Guarantee shall
terminate upon (i) full payment of the Redemption Price of all Common
Securities, (ii) upon the distribution of the Debentures to the Holders of all
of the Common Securities or (iii) upon full payment of the amounts payable in
accordance with the Declaration upon liquidation of the Issuer. Notwithstanding
the foregoing, this Common Securities Guarantee will continue to be effective or
will be reinstated, as the case may be, if at any time any Holder of Common
Securities must restore payment of any sums paid under the Common Securities or
under this Common Securities Guarantee.

                                  ARTICLE VIII.

responsible or accountable in damages or otherwise to the Guarantor or any
Covered Person for any loss, damage

                                       14

<Page>

or claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith in accordance with this Common Securities
Guarantee and in a manner that such Indemnified Person reasonably believed to be
within the scope of the authority conferred on such Indemnified Person by this
Common Securities Guarantee or by law, except that an Indemnified Person shall
be liable for any such loss, damage or claim incurred by reason of such
Indemnified Person's negligence or willful misconduct with respect to such acts
or omissions.

          (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Guarantor and upon such information, opinions,
reports or statements presented to the Guarantor by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Guarantor, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Common Securities might properly be paid.

          SECTION 8.2. INDEMNIFICATION. (a) To the fullest extent permitted by
applicable law, the Guarantor shall indemnify and hold harmless each Indemnified
Person from and against any loss, damage or claim incurred by such Indemnified
Person by reason of any act or omission performed or omitted by such Indemnified
Person in good faith in accordance with this Guarantee Agreement and in a manner
such Indemnified Person reasonably believed to be within the scope of authority
conferred on such Indemnified Person by this Guarantee Agreement, except that no
Indemnified Person shall be entitled to be indemnified in respect of any loss,
damage or claim incurred by such Indemnified Person by reason of negligence or
willful misconduct with respect to such acts or omissions.

          (b) To the fullest extent permitted by applicable law, reasonable
expenses (including legal fees) incurred by an Indemnified Person in defending
any claim, demand, action, suit or proceeding shall, from time to time, be
advanced by the Guarantor prior to the final disposition of such claim, demand,
action, suit or proceeding upon receipt by the Guarantor of an undertaking by or
on behalf of the Indemnified Person to repay such amount if it shall be
determined that the Indemnified Person is not entitled to be indemnified as
authorized in Section 8.2(a).

          (c) The obligation to indemnify as set forth in this Section 8.2 shall
survive the termination of the Common Securities Guarantee.

                                   ARTICLE IX.
