Common Securities and (ii) thereafter to the Company Preferred Securityholders.

        Notwithstanding the foregoing, the Tax Matters Partner shall have the
power to alter any such allocations for federal, state, and local income tax

required to withhold and pay over any amounts to any authority with respect to

                          COMPANY PREFERRED SECURITIES

        Section 7.1 COMPANY COMMON SECURITIES AND COMPANY PREFERRED SECURITIES.

        (a)     The Company Securities shall be divided into two classes,
Company Common Securities and Company Preferred Securities. TECO, as the initial
Common Securityholder, shall be deemed to have been issued [_______] Company
Common Securities upon its designation as the Common Securityholder pursuant to
Section 2.2 of this Agreement.

        (b)     A Company Preferred Security shall be represented by the
corresponding Company Preferred Certificate. Company Common Securities shall not
be evidenced by any certificate or other written instrument, but shall only be
evidenced by this Agreement.

        (c)     In purchasing Company Preferred Securities, each Company
Preferred Securityholder agrees with TECO and the Company that TECO, the
Company, and the Company Preferred Securityholders (i) will treat Company
Preferred Securityholders as holders of the Company Preferred Securities for all
purposes, and not as the holders of an interest in TECO or in any other Person
and (ii) will follow allocations made by the Company, pursuant to Section 4.4 of
this Agreement.

        (d)     The Company Common Securities shall rank junior to the Company
Preferred Securities as to payment of dividends. Holders of Company Common
Securities will only receive dividends out of interest payments received by the
Company on the Notes not required to be applied to fund Preferred Dividends with
respect to the Company Preferred Securities or expenses of the Company. So long
as the Company Preferred Securities are outstanding, no dividends or other
distributions (including redemptions and purchases) may be made with respect to
Company Common Securities unless all accrued and unpaid Preferred Dividends on
the Company Preferred Securities have been paid. Upon issuance of the Company
Common Securities as provided in this Agreement, the Company Common Securities
shall be validly issued, fully paid and nonassessable.

                                       18

liquidation preference of $_____________. The specific designation, dividend
rate, liquidation preference, redemption terms, voting rights, exchange
limitations and other powers, preferences and special rights and limitations of
the Company Preferred Securities are set forth in Section 7.3 hereof.

liability company interests in the Company in addition to the Company Common
Securities and the Company Preferred Securities.

        (b)     The Company Preferred Securities shall rank pari passu with each
other and shall rank senior to all other Company Securities in respect of the
right to receive dividends, payments of any Redemption Price or other
distributions and the right to receive payments out of the assets of the
Company, upon voluntary or involuntary dissolution, winding-up or termination of
the Company in accordance with the provisions hereof. All Company Preferred
Securities redeemed, purchased or otherwise acquired by the Company shall be
cancelled. The Company Preferred Securities shall be issued in registered form
only, except as otherwise provided in this Agreement.

        (c)     Neither TECO, the Company, nor any of their respective
Affiliates shall have the right to vote or give or withhold consent with respect
to any Company Preferred Security owned by it, directly or indirectly, and, for
purposes of any matter upon which the Company Preferred Securityholders may vote
or give or withhold consent as provided in this Agreement, Company Preferred
Securities owned by any of TECO, the Company or any of their respective
Affiliates shall be treated as if they were not outstanding.

        Section 7.3 COMPANY PREFERRED SECURITIES.

        (a)     DESIGNATION. There shall hereby be designated as a series of
preferred limited liability company interests in the Company a series identified
as the Company's "______% Company Preferred Securities", liquidation preference
("LIQUIDATION PREFERENCE") $__________.00 per security, and aggregate
Liquidation Preference $_________ (the "COMPANY PREFERRED SECURITIES").

        The holders of the Company Preferred Securities will have no preemptive
rights with respect to any limited liability company interests in the Company or
any other securities of the Company convertible into or carrying rights or
options to purchase any such securities. Company Preferred Securities will not
be convertible into Company Common Securities or any other class or series of
limited liability company interests in the Company and will not be subject to
any sinking fund or other obligation of the Company for its repurchase or
retirement. Upon

                                       19
<PAGE>   21

issuance of the Company Preferred Securities as provided in this Agreement, the
Company Preferred Securities shall be validly issued, fully paid and
nonassessable.

        (b)     PREFERRED DIVIDENDS. Holders of the Company Preferred Securities
shall be entitled to receive, out of funds held by the Company to the extent
that the Company has cash on hand sufficient to permit such payments and funds
legally available therefor, distributions (the "PREFERRED DIVIDENDS") at a rate
of ___% per annum (the "PREFERRED RATE") of the Liquidation Preference of the
Company Preferred Securities. Preferred Dividends shall be cumulative, and will
accumulate whether or not there are funds of the Company available for their
payment. Preferred Dividends shall accrue from __________and, except as provided
below, shall be payable quarterly in arrears on ___________, ___________,
___________ and ___________ of each year, commencing on ___________, 20__, and
ending on _________, ____. Each such date of payment is a "DIVIDEND PAYMENT
DATE" and each period from and including a Dividend Payment Date, or the date of
initial issuance as applicable, to but not including the next Dividend Payment
Date, is a "DIVIDEND PERIOD"; provided, however, that if any Dividend Payment
Date is not a business day, dividends will be payable on the next business day
(and without any interest or other payment in respect of any such delay) except
that, if such business day is in the next succeeding calendar year, payment of
such Preferred Dividend shall be made on the immediately preceding Business Day,
in each case with the same force and effect as if made on such date. Preferred
Dividends shall accrue on a daily accrual basis on the basis of a 360-day year
of twelve 30-day months. Preferred Dividends in arrears will accumulate and
compound quarterly at the Preferred Rate.

        (c)     TECO has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the Notes
for a period not extending, in the aggregate, beyond the maturity date of the
Notes (each, an "EXTENSION PERIOD"). During such Extension Period, no interest
shall be due and payable on the Notes. As a consequence of such deferral,
Preferred Dividends will also be deferred. Despite such deferral, quarterly
Preferred Dividends will continue to accumulate, compounded quarterly, during
any such Extension Period (to the extent permitted by applicable law). Payments
of accrued Preferred Dividends will be payable to Company Preferred
Securityholders as they appear on the books and records of the Company on the
first record date after the end of the Extension Period. Upon the termination of
any Extension Period and the payment of all amounts then due, TECO may commence
a new Extension Period; provided that such Extension Period together with all
such previous and further extensions thereof may not extend beyond the maturity
date of the Notes.

        (d)     RANKING AND LIQUIDATION PREFERENCE. The Company Preferred
Securities will rank senior to the Company Common Securities as to payment of
dividends.

        If full dividends on the Company Preferred Securities are paid on any
Dividend Payment Date and, after giving effect to such payment, the Company has
additional funds available for the payment of dividends, the Company, in its
discretion, may apply such additional funds to pay dividends on the Company
Common Securities.

        Subject to the first sentence of Section 14.5, in the event of any
voluntary or involuntary dissolution, liquidation or winding up of the Company,
after satisfaction of liabilities to creditors, if any, but before any
liquidating distribution is made to holders of the Company Common

                                       20
<PAGE>   22

Securities, holders of the Company Preferred Securities will be entitled to
receive out of the assets of the Company available for distribution in
liquidation, liquidating distributions in respect of the Company Preferred
Securities equal to the "LIQUIDATION PREFERENCE CLAIM AMOUNT." That amount, for
each $__________.00 Liquidation Preference of Company Preferred Securities, is
equal to: (i) $__________.00, plus (ii) unpaid Preferred Dividends thereon with
respect to the current Dividend Period accrued on a daily basis through the date
of liquidation, plus (iii) accrued and unpaid Preferred Dividends, if any, for
any prior Dividend Period, plus (iv) the related amount of premium, if any, paid
by TECO upon the concurrent redemption of a Like Amount of Notes. After the
holders of the Company Preferred Securities have received the Liquidation
Preference Claim Amount with respect to such Securities, holders of the Company
Common Securities will be entitled to share equally and ratably in any remaining
assets of the Company.

        (e)     VOTING RIGHTS. Notwithstanding anything elsewhere in this
Agreement to the contrary, if (i) an Indenture Event of Default occurs and is
continuing; or (ii) TECO is in default on any of its payment or other
obligations under the Guarantee, then the holders of the Company Preferred
Securities will be entitled, by a vote of the majority of the aggregate stated
liquidation preference of outstanding Company Preferred Securities, to appoint
and authorize a special representative of the Company and the holders of the
Company Preferred Securities (the "SPECIAL REPRESENTATIVE") to enforce the
Company's rights under the Notes and the Indenture, and to enforce the
obligations of TECO under the Guarantee. If a Special Representative has been
appointed, the Special Representative shall have the exclusive right to enforce,
or direct the enforcement of, the Company's rights under the Notes and the
Indenture. In furtherance of the foregoing, and without limiting the powers of
any Special Representative so appointed and for the avoidance of any doubt
concerning the powers of the Special Representative, any Special Representative,
in its own name, in the name of the Company, in the name of the holders of the
Company Preferred Securities or otherwise, may, to the fullest extent permitted
by law, institute or cause to be instituted, any proceedings, including, without
limitation, any suit in equity, an action at law or other judicial or
administrative proceeding, to enforce the Company's or the holders of the
Company Preferred Securities' rights directly against TECO (including, without
limitation, the Company's rights under the Indenture or as a holder or
beneficial owner of the Notes), or any other obligor in connection with such
obligations on behalf of the Company or the holders of the Company Preferred
Securities, and may prosecute such proceeding to final judgment or decree,
including any appeals thereof, and enforce the same against TECO or any other
obligor in connection with such obligations and collect, out of the property,
wherever situated, of TECO or any such other obligor upon such obligations, the
monies adjudged or decreed to be payable in the manner provided by law.

        (f)     WITHDRAWAL; REDEPOSIT OF COMPANY PREFERRED SECURITIES. Pursuant
to (and under the circumstances provided for in) the Trust Agreement, any
beneficial owner of the Trust Preferred Securities may withdraw all, but not
less than all, of the Company Preferred Securities represented by such owner's
corresponding Trust Preferred Securities by providing a written notice to the
Trustee, with evidence of ownership in form satisfactory to the Trustee.

        Within a reasonable period after such request has been properly made,
(i) the Trustee shall reduce the amount of Company Preferred Securities
represented by the Company Preferred Certificate held by the Trust, by the
amount (by Liquidation Preference) of Company Preferred

                                       21
<PAGE>   23

Securities to be so withdrawn by the withdrawing Securityholder, and (ii) the
Company shall issue to the withdrawing Securityholder a Company Preferred
Security Certificate, representing the amount (by Liquidation Preference) of
Company Preferred Securities so withdrawn and cause the registration of such
transfer in the Securities Register. It is expected that withdrawn Company
Preferred Securities will only be issued in definitive fully registered form.

        Any holder of Company Preferred Securities may redeposit withdrawn
Company Preferred Securities by delivery to the Trustee of a certificate or
certificates for the Company Preferred Securities to be deposited, properly
endorsed or accompanied, if required by the Trustee, by a properly executed
instrument of transfer of endorsement in form satisfactory to the Trustee and in
compliance with the terms of this Agreement, together with all such
certifications as may be required by the Trustee in its sole discretion and in
accordance with the provisions of the Trust Agreement. Within a reasonable
period after such deposit is properly made, the Company shall cancel the Company
Preferred Securities so deposited and instruct the Trustee to increase the
number of Company Preferred Securities represented by the permanent global
certificate and the Company shall instruct the Trust Preferred Depositary to
increase the number of Trust Preferred Securities represented by the permanent
global certificate held by the Trust Preferred Depositary accordingly.

        (g)     REDEMPTION. The Company Preferred Securities are not redeemable
at the option of the holders of Company Preferred Securities at any time and are
not redeemable by the Company prior to _____________, 20_____, except in whole
upon the occurrence of a Tax Event or an Investment Company Act Event as
provided below.

                        On each Note Redemption Date and on the stated maturity
of the Notes, the Company will be required to redeem a Like Amount of Company
Securities at the Redemption Price. Notice of redemption shall be given by the
Company by first-class mail, postage prepaid, mailed not less than 30 nor more
than 60 days prior to the Redemption Date to each holder of Company Securities
to be redeemed. All notices of redemption shall state: (i) the Redemption Date;
(ii) the Redemption Price; (iii) if less than all the Company Securities are to
be redeemed, the identification and the total Liquidation Amount of the
particular Company Securities to be redeemed; and (iv) that on the Redemption
Date the Redemption Price will become due and payable upon each such Company
Security to be redeemed and that distributions thereon will cease to accrue on
and after said date.

        The Company Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Notes. Redemptions of the Company Securities shall be made and the
Redemption Price shall be payable on each Redemption Date only to the extent
that the Company has funds then on hand and available for the payment of such
Redemption Price. Notwithstanding any provision herein to the contrary, the
Company Preferred Securities shall rank senior to the Company Common Securities
in respect of the right to receive payment of any Redemption Price.

        If the Company gives a notice of redemption in respect of any Company
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, the Company will irrevocably deposit with the Trustee for the Trust funds
sufficient to pay the applicable Redemption Price of the Company Preferred
Securities represented by the Company Preferred

                                       22
<PAGE>   24

Certificate held by the Trust. The Company will irrevocably deposit with a
paying agent funds sufficient to pay the applicable Redemption Price on Company
Preferred Securities, if any, not represented by the Company Preferred
Certificate held by the Trust and will give the paying agent irrevocable
instructions and authority to pay the Redemption Price to the holders thereof
upon surrender of their Company Preferred Securities Certificates.
Notwithstanding the foregoing, Preferred Dividends payable on or prior to the
Redemption Date for any Company Preferred Securities called for redemption shall
be payable to the holders of such Securities as they appear on the Securities
Register for the Company Preferred Securities on the relevant record dates for
the related Dividend Payment Dates. If notice of redemption shall have been
given and funds deposited as required, then immediately prior to the close of
business on the date of such deposit, all rights of Securityholders holding
Company Securities so called for redemption will cease, except the right of such
Securityholders to receive the Redemption Price and any Dividend payable on or
prior to the Redemption Date, but without interest, and such Securities will
cease to be outstanding. In the event that any date on which any Redemption
Price is payable is not a Business Day, then payment of the Redemption Price
payable on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day falls in the next calendar year, such payment
will be made on the immediately preceding Business Day, in each case, with the
same force and effect as if made on such date. In the event that payment of the
Redemption Price in respect of any Company Preferred Securities called for
redemption is improperly withheld or refused and not paid either by the Company
or by TECO pursuant to the Guarantee, Preferred Dividends on such Company
Preferred Securities will continue to accrue, at the then applicable rate, from
the Redemption Date originally established by the Company for such Company
Preferred Securities to the date such Redemption Price is actually paid, in
which case the actual payment date will be the date fixed for redemption for
purposes of calculating the Redemption Price.

        Payment of the Redemption Price on the Company Preferred Securities
shall be made to the recordholders thereof as they appear on the Securities
Register for the Company Preferred Securities on the relevant record date, which
shall be fifteen calendar days prior to the relevant Redemption Date.

        If less than all the Company Securities are to be redeemed on a
Redemption Date, then no Company Common Securities shall be redeemed unless and
until all Company Preferred Securities have been redeemed. The particular
Company Preferred Securities to be redeemed shall be selected on a pro rata
basis (based upon Liquidation Amounts) not more than 60 days prior to the
Redemption Date by the Company from the outstanding Company Preferred Securities
not previously called for redemption which may provide for the selection for
redemption of portions (equal to $____ or an integral multiple of $___ in excess
thereof) of the Liquidation Amount of Preferred Securities of a denomination
larger than $____. The Company shall promptly notify the Trustee and the
Registrar in writing of the Company Preferred Securities selected for redemption
and, in the case of any Company Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Agreement, unless the context otherwise requires, all provisions relating
to the redemption of Company Preferred Securities shall relate, in the case of
any Company Preferred Securities redeemed or to be redeemed only in part, to the
portion of the Liquidation Amount of Company Preferred Securities that has been
or is to be redeemed.

                                       23
<PAGE>   25

        The Company will also have the right at any time prior to
_______________, 20_______, upon the occurrence of a Tax Event or an Investment
Company Act Event, and on not less than 30 or more than 60 days' notice by mail,
to redeem Company Preferred Securities, in whole (but not in part) at a
redemption price per security equal to the Redemption Price.

        Notwithstanding the foregoing, the Company Preferred Securities will not
be subject to any sinking fund or mandatory redemption.

        Any Company Preferred Securities redeemed shall be canceled. There shall
be no prescription period in respect of uncollected dividends on the Company
Preferred Securities.

        (h)     RIGHTS OF HOLDERS OF TRUST PREFERRED SECURITIES UNDER THE
COMPANY PREFERRED SECURITIES. To the fullest extent permitted by law, without
the need for any other action of any Person, including the Trustee and any other
holder of the Trust Preferred Securities, each holder of the Trust Preferred
Securities shall be entitled to enforce in the name of the Trust the Trust's
rights under the Company Preferred Securities represented by the Trust Preferred
Securities held by such holder.

        (i)     SUBORDINATION OF COMPANY COMMON SECURITIES. If on any Dividend
Payment Date or Redemption Date any Event of Default resulting from an Indenture
Event of Default shall have occurred and be continuing, no payment of any
Dividend on, or Redemption Price of, any Company Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of
Company Common Securities, shall be made unless payment in full in cash of all
accumulated and unpaid Preferred Dividends on all outstanding Company Preferred
Securities for all Dividend Periods terminating on or prior thereto, or in the
case of payment of the Redemption Price the full amount of such Redemption Price
on all outstanding Company Preferred Securities, shall have been made or
provided for, and all funds immediately available to the Company shall first be
applied to the payment in full in cash of all Preferred Dividends on, or the
Redemption Price of, Preferred Securities then due and payable. In the case of
the occurrence of any Event of Default resulting from any Indenture Event of
Default, the holders of Company Common Securities will be deemed to have waived
any right to act with respect to any such Event of Default under this Agreement
until the effect of all such Events of Default with respect to the Company
Preferred Securities have been cured, waived or otherwise eliminated. Until any
such Event of Default under this Agreement with respect to the Company Preferred
Securities has been so cured, waived or otherwise eliminated, the Board of
Directors shall act solely on behalf of the holders of the Company Preferred
Securities and not the holders of the Company Common Securities, and only the
holders of the Company Preferred Securities will have the right to direct the
Board of Directors to act on their behalf.

                                  ARTICLE VIII
                               VOTING AND MEETINGS

        Section 8.1 VOTING RIGHTS OF COMPANY PREFERRED SECURITYHOLDERS.

        (a)     Except as shall be otherwise expressly provided herein, in the
By-Laws, or as otherwise required by the Delaware Act, the Company Preferred
Securityholders shall have no

                                       24
<PAGE>   26

right or power to vote on any question or matter or in any proceeding or to be
represented at, or to receive notice of, any meeting of Securityholders.

        (b)     For so long as any Company Preferred Securities remain
Outstanding, if, upon a Note Event of Default, the Indenture Trustee fails or
the holders of not less than 25% in aggregate principal amount of the
outstanding Notes fail to declare the principal of all of the Notes to be
immediately due and payable, the holders of at least 25% in aggregate
Liquidation Preference of the Company Preferred Securities shall have such right
by a notice in writing to TECO and the Indenture Trustee; and upon any such
declaration such principal amount of and the accrued interest on all of the
Notes shall become immediately due and payable; provided that the payment of
principal and interest on such Notes shall remain subordinated to the extent
provided in the Indenture. At any time after such a declaration of acceleration
with respect to the Notes has been made and before a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as in the
Indenture provided, the holders of a majority in Liquidation Preference of the
Company Preferred Securities, by written notice to Registrar, TECO and the
Indenture Trustee may rescind and annul such declaration and its consequences
if:

                (i)     TECO has paid or deposited with the Indenture Trustee a
        sum sufficient to pay

                        (A)     all overdue installments of interest on all of
the Notes,

                        (B)     the principal of (and premium, if any, on) any
Notes which have become due otherwise than by such declaration of acceleration
and interest thereon at the rate borne by the Notes, and

                        (C)     all sums paid or advanced by the Indenture
Trustee under the Indenture and the reasonable compensation, expenses,
disbursements and advances of the Indenture Trustee, its agents and counsel; and

                (ii)    all Events of Default with respect to the Notes, other
        than the non-payment of the principal of the Notes which has become due
        solely by such acceleration, have been cured or waived as provided in
        Section 502 of the Indenture.

        The holders of a majority in aggregate Liquidation Preference of the
Company Preferred Securities may, on behalf of the holders of all the Company
Preferred Securities, waive any past default under the Indenture, except a
default in the payment of principal or interest (unless such default has been
cured and a sum sufficient to pay all matured installments of interest and
principal due otherwise than by acceleration has been deposited with the
Indenture Trustee) or a default in respect of a covenant or provision which
under the Indenture cannot be modified or amended without the consent of the
holder of each outstanding Note. No such waiver or rescission shall affect any
subsequent default or impair any right consequent thereon. Upon receipt by the
Registrar of written notice declaring such an acceleration, or rescission and
annulment thereof, by holders of the Company Preferred Securities all or part of
which is represented by Book-Entry Company Preferred Securities Certificates, a
record date shall be established for determining holders of outstanding Company
Preferred Securities entitled to join in such notice, which record date shall be
at the close of business on the day the Registrar

                                       25
<PAGE>   27

receives such notice. The holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such holders remain holders after such record date; provided,
that, unless such declaration of acceleration, or rescission and annulment, as
the case may be, shall have become effective by virtue of the requisite
percentage having joined in such notice prior to the day which is 90 days after
such record date, such notice of declaration of acceleration, or rescission and
annulment, as the case may be, shall automatically and without further action by
any holder be canceled and of no further effect. Nothing in this paragraph shall
prevent a holder, or a proxy of a holder, from giving, after expiration of such
90-day period, a new written notice of declaration of acceleration, or
rescission and annulment thereof, as the case may be, that is identical to a
written notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 8.1(b).

        (c)     For so long as any Company Preferred Securities remain
Outstanding, to the fullest extent permitted by law and subject to the terms of
this Agreement and the Indenture, upon a Note Event of Default specified in
Section 501(1) or 501(2) of the Indenture, any holder of Company Preferred
Securities shall have the right to institute a proceeding directly against TECO,
pursuant to the Indenture, for enforcement of payment to such holder of the
principal amount of or interest on Notes having a principal amount equal to the
Liquidation Preference of the Company Preferred Securities of such holder (a
"DIRECT ACTION"). In connection with any such Direct Action, TECO will be
subrogated to the rights of any holder of the Company Preferred Securities to
the extent of any payment made by TECO to such holder of Company Preferred
Securities as a result of such Direct Action.

        (d)     Notwithstanding that Securityholders holding Company Preferred
Securities are entitled to vote or consent under any of the circumstances
described in this Agreement or the By-Laws, any of the Company Preferred
Securities that are owned by TECO, the Common Securityholder, the Company or any
of their respective Affiliates, either directly or indirectly, shall not be
entitled to vote or consent and shall, for the purposes of such vote or consent,
be treated as if they were not outstanding.

        Section 8.2 VOTING RIGHTS OF COMMON SECURITYHOLDERS. Except as otherwise
provided herein and subject to the limited rights of holders of the Company
Preferred Securities, and except as otherwise provided by the Delaware Act, all
voting rights of the Securityholders shall be vested in the Common
Securityholders. The Company Common Securities shall entitle the Common
Securityholders to vote in proportion to the stated amounts represented by their
Company Common Securities.

        Section 8.3 MEETINGS OF THE SECURITYHOLDERS.

        (a)     Meetings of the Securityholders of any class or of all classes
of Securities may be called at any time by the Board of Directors or as provided
by this Agreement or the By-Laws. Except to the extent otherwise provided, the
following provisions shall apply to meetings of Securityholders.

                                       26
<PAGE>   28

        (b)     Securityholders may vote in person or by proxy at such meeting.
Whenever a vote, consent or approval of Securityholders is permitted or required
under this Agreement, such vote, consent or approval may be given at a meeting
of Securityholders or by written consent.

        (c)     Each Securityholder may authorize any Person to act for it by
proxy on all matters in which a Securityholder is entitled to participate,
including waiving notice of any meeting or voting or participating at a meeting.
Every proxy must be signed by the Securityholder or its attorney-in-fact. Every
proxy shall be revocable at the pleasure of the Securityholder executing it at
any time before it is voted.

        (d)     Each meeting of Securityholders shall be conducted by the Board
of Directors or by such other Person that the Board of Directors may designate.

        (e)     Any required approval of Company Preferred Securityholders may
be given at a separate meeting of such Company Preferred Securityholders
convened for such purpose or at a meeting of Securityholders of the Company or
pursuant to written consent. The Board of Directors shall cause a notice of any
meeting at which Company Preferred Securityholders holding Preferred Securities
are entitled to vote pursuant to Section 7.3, or of any matter upon which action
may be taken by written consent of such Company Preferred Securityholders, to be
mailed to each holder of record of the Company Preferred Securities. Each such
notice shall include a statement setting forth (i) the date of such meeting or
the date by which such action is to be taken, (ii) a description of any action
proposed to be taken at such meeting on which such Company Preferred
Securityholders are entitled to vote or of such matters upon which written
consent is sought and (iii) instructions for the delivery of proxies or
consents.

        (f)     Subject to Section 7.3(e) and Section 8.3(e) of this Agreement,
the Board of Directors, in their sole discretion, shall establish all other
provisions relating to meetings of Securityholders, including notice of the
time, place or purpose of any meeting at which any matter is to be voted on by
any Securityholders, waiver of any such notice, action by consent without a
meeting, the establishment of a record date, quorum requirements, voting in
person or by proxy or any other matter with respect to the exercise of any such
right to vote.

                                   ARTICLE IX
                                    DIVIDENDS

        Section 9.1 DIVIDENDS.

        (a)     Subject to the terms of this Article 9 and the provisions of the
Delaware Act: (i) Company Preferred Securityholders shall receive periodic
distributions ("DIVIDENDS") in accordance with Article 7 of this Agreement, out
of funds held by the Company to the extent that the Company has cash on hand
sufficient to permit such distributions, and (ii) subject to the rights of the
Company Preferred Securityholders as set forth in Article 7, Common
Securityholders shall receive Dividends when, as and if declared by the Board of
Directors, in its discretion.

        (b)     A Securityholder shall not be entitled to receive any Dividend
or other distribution with respect to any Dividend Payment Date (and any such
Dividend or other distribution shall not be considered due and payable),
irrespective of whether such Dividend or

                                       27
<PAGE>   29

other distribution is payable automatically or has been declared by the
Directors, until such time as the Company shall have funds legally available for
the payment of such dividend to such Securityholder pursuant to the terms of
this Agreement and the Delaware Act, and notwithstanding any provision of
Section 18-606 of the Delaware Act to the contrary, until such time, a
Securityholder shall not have the status of a creditor of the Company, or the
remedies available to a creditor of the Company.

        Section 9.2 LIMITATIONS ON DISTRIBUTIONS. Notwithstanding any provision
to the contrary contained in this Agreement, the Company shall not make a
distribution (including a Dividend or redemption payment) to any Securityholder
on account of a Company Security if such distribution would violate Section
18-607 of the Delaware Act or other applicable law.

        Section 9.3 PAYMENT. The Company will make payments in respect of the
Company Preferred Securities, at its election, by check or by crediting the

its discretion, deems necessary or desirable to perfect such designation,

Company may treat the Person in whose name any Company Preferred Certificate
shall be registered on the books and records of the Company as the sole holder
of such Company Preferred Certificate and of the Company Preferred Securities

dividends or other distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Company Preferred Certificate or in the Company Preferred
Securities represented by such Company Preferred Certificate on the part of any
other Person, whether or not the Company shall have actual or other notice
thereof. Notwithstanding the foregoing or anything to the contrary herein, the
Company agrees that at any time that the Trust shall be a holder of any Company
Preferred Securities, each holder of a preferred certificate issued by the Trust
shall, upon presentation to the Company or the Registrar of reasonable evidence
thereof, have the right to the fullest extent permitted by law and without the
need for any other action of any other Person, including the Trustee under the
Trust and any other holder of any other of such preferred certificates, (a) to
enforce in the name of the Trust the Trust's rights under the Company Preferred
Securities represented by the preferred certificates of such holder and (b) to
withdraw from the Trust upon written notice to such Trustee and the Company and
hold directly the underlying Company Preferred Securities represented by such
preferred certificates.

<PAGE>   32

Secretary of the Company. Company Preferred Certificates, other than Company
Preferred Certificates held by the Trust, shall also be manually signed by the
Registrar. Company Preferred Certificates bearing the signatures of individuals
who were, at the time when such signatures shall have been affixed, authorized
to sign on behalf of the Company shall be validly issued notwithstanding that
such individuals or any of them shall have ceased to be so authorized prior to
the delivery of such Company Preferred Certificates or did not hold such offices
at the date of delivery of such Company Preferred Certificates. A transferee of
a Company Preferred Certificate shall become a Securityholder, upon due
registration of such Company Preferred Certificate in such transferee's name

        Section 13.5 TRANSFER OF COMPANY PREFERRED CERTIFICATES.

        (a)     The Board of Directors shall provide for the registration and
transfer of Company Preferred Certificates in a record thereof (each a
"SECURITIES REGISTER") and shall appoint a securities registrar and transfer
agent (the "REGISTRAR") to act on its behalf, or may act as its own Registrar;
provided, however, that without any action on the part of the Board of Directors
being necessary, The Bank of New York, or any of its Affiliates, may be
appointed as the initial Registrar by any officer of the Company. Subject to the
other provisions of this Article 13, upon surrender for registration of transfer
of any Company Preferred Certificate, the Board of Directors shall cause one or
more new Company Preferred Certificates to be issued in the name of the
designated transferee or transferees. Every Company Preferred Certificate
surrendered for registration of transfer shall be accompanied by a written
instrument of transfer in form satisfactory to the Board of Directors duly
executed by the Company Preferred Securityholder or his or her attorney duly
authorized in writing. Any registration of transfer shall be effected upon the
Registrar being satisfied with the documents of title and identity of the Person
making the request, upon the receipt by the Registrar of any applicable
certificate relating to transfer restrictions as described below, and subject to
such reasonable regulations as the Company may from time to time establish. Each
Company Preferred Certificate surrendered for registration of transfer shall be
canceled by the Registrar. A transferee of a Company Preferred Certificate shall
be admitted to the Company, as a Company Preferred Securityholder and shall be
entitled to the rights and subject to the obligations of a Company Preferred
Securityholder hereunder upon receipt by such transferee of a Company Preferred
Certificate. By acceptance of a Company Preferred Certificate, each transferee
shall be bound by this Agreement. The transferor of a Company Preferred
Certificate, in whole, shall cease to be a Company Preferred Securityholder at
the time that the transferee of such Company Preferred Certificate is admitted
to the Company as a Company Preferred Securityholder in accordance with this
Section 13.5.

        (b)     Upon surrender for registration of transfer of any Company
Preferred Certificate at the office or agency of the Company or the Registrar
maintained for that purpose, subject to Section 13.6, the Company shall deliver
or cause to be delivered to the Registrar in a form duly executed on behalf of
the Company in the manner provided for in Section 13.4(a), and the Registrar
shall countersign in the manner provided in and to the extent required by
Section 13.4(a) and deliver, in the name of the designated transferee or
transferees, one or more new Company Preferred Certificates in authorized
denominations of a like aggregate liquidation preference dated the date of
execution by such Registrar.

                                       31
<PAGE>   33

        The Registrar shall not be required, (i) to issue, register the transfer
of or exchange any Company Preferred Security during a period beginning at the
opening of business 15 days before the day of selection for redemption of such
Company Preferred Securities and ending at the close of business on the day of
mailing of the notice of redemption, or (ii) to register the transfer of or
exchange any Company Preferred Security so selected for redemption in whole or
in part, except, in the case of any such Company Preferred Security to be
redeemed in part, any portion thereof not to be redeemed.

        No service charge shall be made for any registration of transfer or
exchange of Company Preferred Certificates, but the Registrar may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer or exchange of Company Preferred
Certificates.

        (c)     A Company Preferred Certificate may be transferred after the
Exchange Date as provided in Section 13.5(a), in whole or in part, to a Person
who takes delivery, in the form of another Company Preferred Certificate.

        Section 13.6 MUTILATED, DESTROYED, LOST OR STOLEN COMPANY PREFERRED
CERTIFICATES. If (a) any mutilated Company Preferred Certificate shall be
surrendered to the Registrar, or if the Registrar shall receive evidence to its
satisfaction of the destruction, loss or theft of any Company Preferred
Certificate, and (b) there shall be delivered to the Registrar and the Company
such security or indemnity as may be required by them to save each of them
harmless, then in the absence of notice that such Company Preferred Certificate
shall have been acquired by a protected purchaser, the Company shall sign, the
Registrar shall countersign to the extent required under Section 13.4(a), and
the Company and the Registrar shall make available for delivery (all in the
manner provided for in Section 13.4), in exchange for or in lieu of any
mutilated, destroyed, lost or stolen Company Preferred Certificate, a new
Company Preferred Certificate of like class, tenor and denomination. In
connection with the issuance of any new Company Preferred Certificate under this
Section 13.6, the Company or the Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Company Preferred Certificate issued
pursuant to this Section shall constitute conclusive evidence of a limited
liability company interest in the Company corresponding to that evidenced by the
lost, stolen or destroyed Company Preferred Certificate, as if originally
issued, whether or not the lost, stolen or destroyed Company Preferred
Certificate shall be found at any time.

        Section 13.7 BOOK-ENTRY COMPANY PREFERRED CERTIFICATES.

        Upon the distribution of the Company Preferred Securities to the holders
of the Trust Preferred Securities in accordance with the provisions of the Trust
Agreement, the Company Preferred Certificates will be issued in the form of a
typewritten Company Preferred Certificate or Certificates representing
Book-Entry Company Preferred Certificates and delivered to the Clearing Agency
and registered on the Securities Register in the name of the nominee of the
Clearing Agency, and no beneficial owner will receive a Definitive Company

Company Preferred Securities, except as provided in Section 13.10. Thereafter,
unless and until Definitive Company Preferred Certificates have been issued to
beneficial owners pursuant to Section 13.10:

<PAGE>   34

        (a)     the provisions of this Section 13.8 shall be in full force and
effect;

        (b)     the Registrar and the Company shall be entitled to deal with the
Clearing Agency for all purposes of this Agreement relating to the Book-Entry
Company Preferred Certificates (including the payment of the Liquidation Amount
of and distributions on the Book-Entry Company Preferred Certificate and the
giving of instructions or directions to Owners of Book-Entry Company Preferred
Securities) as the sole holder of Book-Entry Company Preferred Securities and
shall have no obligations to the Owners thereof;

        (c)     to the extent that the provisions of this Section 13.8 conflict
with any other provisions of this Agreement, the provisions of this Section 13.8
shall control; and

        (d)     the rights of the Owners of the Book-Entry Company Preferred
Certificates shall be exercised only through the Clearing Agency and shall be
limited to those established by law and agreements between such Owners and the
Clearing Agency and/or the Clearing Agency Participants. Pursuant to the
Certificate Depository Agreement, unless and until Definitive Company Preferred
Certificates are issued pursuant to Section 13.10, the initial Clearing Agency
will make book-entry transfers among the Clearing Agency Participants and
receive and transmit payments on the Company Preferred Securities to such
Clearing Agency Participants.

        Section 13.8 NOTICES TO CLEARING AGENCY.

        To the extent that a notice or other communication to the Owners is
required under this Agreement, from and after the date on which Company
Preferred Certificates shall have been delivered to a Clearing Agency, unless
and until Definitive Company Preferred Certificates shall have been issued to
Owners pursuant to Section 13.10, the Company shall give all such notices and
communications specified herein to be given to Owners to the Clearing Agency,
and shall have no obligations to the Owners.

        Section 13.9 DEFINITIVE COMPANY PREFERRED CERTIFICATES.

        If (a) the Clearing Agency is no longer willing or able to properly
discharge its responsibilities with respect to the Company Preferred
Certificates, and the Company is unable to locate a qualified successor, (b) the
Company elects to terminate the book-entry system through the Clearing Agency or
(c) after the occurrence of a Note Event of Default, Owners of Company Preferred
Certificates representing beneficial ownership interests aggregating at least a
majority of the Liquidation Amount advise the Company in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Company Preferred Certificates, then the
Company shall notify the Clearing Agency and the Clearing Agency shall notify
all Owners of Company Preferred Certificates of the occurrence of any such event
and of the availability of the Definitive Company Preferred Certificates to
Owners requesting the same. Upon surrender to the Registrar of the typewritten
Company Preferred Certificate or Certificates representing the Book-Entry
Company Preferred Certificates by the Clearing Agency, accompanied by
registration instructions, the Company shall execute the Definitive Company
Preferred Certificates in accordance with the instructions of the Clearing
Agency. Neither the Registrar nor the Company shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions.

Upon the issuance of Definitive Company Preferred Certificates, the Company and
the Registrar shall recognize the holders of the Definitive Company Preferred
Certificates as Securityholders. The Definitive Company Preferred Certificates

manner as is reasonably acceptable to the Company, as evidenced by the execution
thereof by the Company.

                    DISSOLUTION, LIQUIDATION AND TERMINATION

        Section 14.1 NO DISSOLUTION. The Company shall not be dissolved by the
admission of Securityholders. The death, insanity, retirement, resignation,
expulsion, bankruptcy or dissolution of a Securityholder, or the occurrence of
any other event which terminates the continued membership of a Securityholder in
the Company, shall not in and of itself cause the Company to be dissolved and
its affairs wound up. Upon the occurrence of any such event, the business of the
Company shall be continued without dissolution. The Bankruptcy of a
Securityholder shall not cause a Securityholder to cease to be a member of the
Company.

        Section 14.2 EVENTS CAUSING DISSOLUTION. The Company shall be dissolved
and its affairs shall be wound up in accordance with the Delaware Act if any of
the following events occur:

        (a)     a decree or order by a court of competent jurisdiction shall
have been entered adjudging the Company a bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or
composition of the Company under any applicable federal or state bankruptcy or
similar law, and such decree or order shall have continued undischarged and
unstayed for a period of 90 days; or a decree or order of a court having
jurisdiction in the premises for the appointment of a receiver, liquidator,
trustee, assignee, sequestrator or similar official in bankruptcy or insolvency
of the Company or of all or substantially all of its property, or for the
winding up or liquidation of its affairs, shall have been entered, and such
decree or order shall have continued undischarged and unstayed for a period of
90 days or the Company shall institute proceedings to be adjudicated a voluntary
bankrupt, or shall consent to the filing of a bankruptcy proceeding against it,
or shall file a petition or answer or consent seeking reorganization,
arrangement, adjustment or composition under any applicable federal or state
bankruptcy or similar law, or shall consent to the filing of any such petition,
or shall consent to the appointment of a receiver, liquidator, trustee,
assignee, sequestrator or similar official in bankruptcy or insolvency of the
Company or of all or substantially all of its property, or shall make an
assignment for the benefit of creditors, or shall admit in writing its inability
to pay its debts generally as they become due and its willingness to be adjudged
a bankrupt, or limited liability company action shall be taken by the Company in
furtherance of any of the aforesaid purposes;

        (b)     TECO is liquidated;

        (c)     the entry of a decree of judicial dissolution of the Company
under Section 18-802 of the Delaware Act;

                                       34
<PAGE>   36

        (d)     TECO's written direction, as holder of the Company Common
Securities, to the Board of Directors at any time (which direction is optional
and wholly within the discretion of TECO), to dissolve the Company and
distribute the Notes to the holders of the Company Preferred Securities; or

        (e)     the redemption of all of the Company Securities.

        Notwithstanding the foregoing, the Company shall not be dissolved until
all claims under the Guarantee Agreement shall have been paid in full pursuant
to its terms, to the fullest extent permitted by law.

        Section 14.3 NOTICE OF DISSOLUTION. Upon the dissolution of the Company,
the Board of Directors shall promptly notify the Securityholders of such
dissolution.

        Section 14.4 LIQUIDATION. Upon dissolution of the Company, the Board of
Directors or, in the event that the dissolution is caused by an event described
in Sections 14.2(b) or (c) of this Agreement and there are no Directors, a
Person or Persons who may be approved by the Company Preferred Securityholders
holding not less than a majority in liquidation amount, as liquidating trustees,
shall immediately commence to wind up the Company's affairs; provided, however,
that a reasonable time shall be allowed for the orderly liquidation of the
assets of the Company and the satisfaction of liabilities to creditors so as to
minimize the losses attendant upon a liquidation. The proceeds of liquidation
shall be distributed, as realized, in the manner provided in Section 18-804 of
the Delaware Act, subject to the provisions of Section 14.5.

        Section 14.5 CERTAIN RESTRICTIONS ON LIQUIDATION PAYMENTS. In the event
of any voluntary or involuntary dissolution of the Company, the board of
directors will distribute (after satisfying any liabilities to the Company's
creditors as provided by applicable law) to the holders of the Company
Securities a Like Amount of the Notes. However, if that distribution is
determined to be impractical by the Board of Directors, the holders of the
Company Securities will be entitled to receive out of the Company's assets
available for distribution to holders (after any liabilities to the Company's
creditors as provided by applicable law) a liquidation distribution in an amount
equal to the amounts set forth, and in the priority prescribed, in Section
7.3(d). If such liquidation distribution to the Company Preferred
Securityholders can be paid only in part because the Company has insufficient
assets available to pay in full the aggregate liquidation distribution, then the
amounts payable directly by the Company on its Company Preferred Securities will
be paid on a pro rata basis based on the Liquidation Amount

        Section 14.6 Designation of Successor Depositor. In the event of the
dissolution of the Company, TECO shall appoint an entity wholly owned and
controlled, directly or indirectly, by TECO as successor Depositor (as defined
in the Trust Agreement) to exercise all rights and perform all obligations as
the Depositor under the Trust Agreement. .

        Section 14.7 TERMINATION. This Agreement will terminate upon the latest
to occur of the redemption of all of the Company Preferred Securities, a final
distribution in respect of the Company Preferred Securities and delivery of such
distribution to the holders of the Company Preferred Securities, or dissolution,
winding up and termination of the Company.

                                  MISCELLANEOUS

        Section 15.1 AMENDMENTS. TECO may, at any time and from time to time,
enter into one or more agreements supplemental to this Agreement and the
Guarantee Agreement without the consent of the holders of the Company Preferred
Securities: (i) to evidence the succession of another entity to TECO and the
assumption by any such successor of the covenants of TECO in this Agreement;
(ii) to add to the covenants of TECO for the benefit of the holders of the
Company Preferred Securities, or to surrender any right or power therein
conferred upon TECO, (iii) to cure any ambiguity or correct or supplement any
provision in this Agreement which may be defective or inconsistent with any
other provision therein or to make any other provisions with respect to matters
or questions arising under this Agreement in a way consistent with the other
provisions of this Agreement; provided that any such action shall not materially
adversely affect the interests of the holders of the Company Preferred
Securities; or (iv) to modify, eliminate or add to any provisions of the limited
liability company agreement if necessary to ensure that the Company will be
classified for United States federal income tax purposes as a partnership or to
ensure that the Company will not be required to be registered under the 1940
Act. Any other amendment of this Agreement and the Guarantee Agreement must be
approved by holders of a majority of the Company Preferred Securities and the
Company must have received an Opinion of Counsel experienced in such matters to
the effect that the amendment or the exercise of any power granted in accordance
with the amendment will not affect the Company's status as a partnership for
United States federal income tax purposes or the Company's exemption from status
as an "investment company" under the 1940 Act. However, without the consent of
each holder of Company Preferred Securities, no amendment may: (i) change the
amount or timing of any distribution on the Company Preferred Securities or
otherwise adversely affect the amount of any distribution required to be made in
respect of the Company Preferred Securities as of a specified date; or (ii)
restrict the right of a holder of Trust Preferred Securities to sue for the
enforcement of any distribution payment. The Company must notify each holder of
Company Preferred Securities whenever it is notified of a default with respect
to the Notes.

        Section 15.2 NOTIFICATION; AMENDMENT OF CERTIFICATE OF FORMATION. In the
event this Agreement shall be amended pursuant to Section 15.1, the Board of
Directors shall promptly notify all Securityholders of such amendments and cause
the Certificate of Formation to be amended to reflect such change if it deems
such amendment of the Certificate of Formation to be necessary or appropriate.

        Section 15.3 SUCCESSORS. This Agreement shall be binding as to the
executors, administrators, estates, heirs and legal successors, or nominees or
representatives, of the Securityholders.

        Section 15.4 LAW; SEVERABILITY. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware. In particular,
this Agreement shall be construed to the maximum extent possible to comply with
all of the terms and conditions of the Delaware Act. If, nevertheless, it shall
be determined by a court of competent jurisdiction that any provisions or
wording of this Agreement shall be invalid or unenforceable under the Delaware
Act or other applicable law, such invalidity or unenforceability shall not
invalidate the

                                       36
<PAGE>   38

entire Agreement. In that case, this Agreement shall be construed so as to limit
any term or provision so as to make it enforceable or valid within the
requirements of applicable law, and, in the event such term or provisions cannot
be so limited, this Agreement shall be construed to omit such invalid or
unenforceable provisions. If it shall be determined by a court of competent
jurisdiction that any provision relating to the distributions and allocations of
the Company or to any fee payable by the Company is invalid or unenforceable,
this Agreement shall be construed or interpreted so as (a) to make it
enforceable or valid and (b) to make the distributions and allocations as
closely equivalent to those set forth in this Agreement as is permissible under
applicable law.

        Section 15.5 FILINGS. Following the execution and delivery of this
Agreement, the Board of Directors shall cause to be promptly prepared any
documents required to be filed and recorded under the Delaware Act, and the
Board of Directors shall cause to be promptly filed and recorded each such
document in accordance with the Delaware Act and, to the extent required by
local law, to be filed and recorded or notice thereof to be published in the
appropriate place in each jurisdiction in which the Company may hereafter
establish a place of business. The Board of Directors shall also promptly cause
to be filed, recorded and published such statements of fictitious business name
and any other notices, certificates, statements or other instruments required by
any provision of any applicable law of the United States or any, state or other
jurisdiction which governs the conduct of its business from time to time.

        Section 15.6 POWER OF ATTORNEY. Each Company Preferred Securityholder
does hereby constitute and appoint each Person specifically authorized by the
Board of Directors to act as its true and lawful representative and
attorney-in-fact, in its name, place and stead to make, execute, sign, deliver
and file (a) any amendment of the Certificate of Formation required because of
an amendment to this Agreement or in order to effectuate any change in the
ownership of the Company Securities, (b) any amendments to this Agreement made
in accordance with the terms hereof and (c) all such other instruments,
documents and certificates which may from time to time be required by the laws
of the United States of America, the State of Delaware or any other
jurisdiction, or any political subdivision or agency thereof, to effectuate,
implement and continue the valid and subsisting existence of the Company or to
dissolve the Company or for any other purpose consistent with this Agreement and
the transactions contemplated hereby.

        The power of attorney granted hereby is coupled with an interest and

disability, dissolution, termination or bankruptcy of the Company Preferred
Securityholder granting the same or the transfer of all or any portion of such
Company Preferred Securityholder's Preferred Securities and (b) extend to such
Company Preferred Securityholder's successors, assigns and legal

of a Director, such Director's fiduciary duty (if any) or, in the case of a
Director or an Officer, for any act or omission performed or omitted by such
Director or Officer in good faith on behalf of the Company, except for such
Director's or Officer's gross negligence or willful misconduct.

                                       37
<PAGE>   39

        (b)     Each Director and Officer shall be fully protected in relying in
good faith upon the records of the Company and upon such information, opinions,
reports or statements presented to the Company by any Person as to matters that
such Director or Officer 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 Company, 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 Securityholders might properly be paid.

        Section 15.8 INDEMNIFICATION. To the fullest extent permitted by
applicable law, each Director and Officer shall be entitled to indemnification
from the Company for any loss, damage, claim or expense (including reasonable
attorney's fees) incurred by such Director or Officer by reason of any act or
omission performed or omitted by such Director or Officer in good faith on
behalf of the Company and in a manner reasonably believed to be within the scope
of authority conferred on such Director or Officer by this Agreement, except
with respect to any act or omission determined by a court of competent
jurisdiction to have constituted gross negligence or willful misconduct of such
Director or Officer; provided, however, that any indemnity under this Section
15.8 shall be provided out of and to the extent of any director and officer
insurance policy, and no Securityholder shall have any personal liability on
account thereof. The right to indemnification under this Section 15.8 is a
contract right. The Company may purchase and maintain insurance to protect any
Director or Officer against liability asserted against him or her, or incurred
by him or her, arising out of his or her status as such.

        Without limiting the foregoing, the Company's directors shall have no
personal liability to the Company or its Securityholders for monetary damages
(i) for not voting to take enforcement action with respect to the Notes owned by
the Company, if any, prior to the occurrence of a Bankruptcy of the Company or
(ii) at any time for breach of any such director's fiduciary duty (if any)
except for such director's gross negligence or willful misconduct.

        Section 15.9 ADDITIONAL DOCUMENTS. Each Company Preferred

        have no obligation to indemnify any Administrator Indemnified Person

obligations under the Transaction Documents.

Board of Directors, to be held at such date, time and place, either within or
without the State of Delaware and outside of the State of Florida, except in the
case of an emergency, in which case meetings may be held within the State of
Florida, as may be stated in the notice of the meeting. A special meeting of
Securityholders shall be called by the Secretary upon the written request,
stating the purpose of the meeting, of Securityholders who together own of
record a majority of the Securities entitled to vote at such meeting.

        Section 1.3 Notice of Meetings. Whenever Securityholders are required or
permitted to take any action at a meeting, a written notice of the meeting shall
be given which shall state the place, date and hour of the meeting, and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called. Unless otherwise provided by law, the written notice of any meeting
shall be given not less than ten nor more than sixty days before the date of the
meeting to each Securityholder entitled to vote at such meeting. If mailed, such
notice shall be

<PAGE>   53

deemed to be given when deposited in the United States mail, postage prepaid,
directed to the Securityholder at such Securityholder's address as it appears on
the records of the Company.

        Section 1.4 Adjournments. Any meeting of Securityholders, annual or
special, may be adjourned from time to time, to reconvene at the same or some
other place, and notice need not be given of any such adjourned meeting if the
time and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the Company may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than thirty days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each Securityholder of record entitled to vote at the meeting.

        Section 1.5 Quorum. At each meeting of Securityholders, except where
otherwise provided by law or the Agreement or these By-Laws, the holders of at
least 50% of the Company Common Securities and the Company Preferred Securities
(together, the "Securities") entitled to vote on a matter at the meeting,
present in person or represented by proxy, shall constitute a quorum. In the
absence of a quorum of the holders of Securities entitled to vote on a matter,
the holders of a majority of the Securities present or represented may adjourn
such meeting from time to time in the manner provided by Section 1.4 of these
By-Laws until a quorum shall be so present or represented. Securities other than
Common Securities belonging on the record date for the meeting to the Company or
an Affiliate of the Company shall neither be entitled to vote nor be counted for
quorum purposes.

        Section 1.6 Organization. Meetings of Securityholders shall be presided
over by the Chairman of the Board, if any, or in the absence of the Chairman of
the Board by the President, or in the absence of the President by a chairman
designated by the Board of Directors, or in the absence of such designation, by
a chairman chosen at the meeting. The Secretary, or in the absence of the
Secretary, the chairman of the meeting may appoint any person to act as
secretary of the meeting.

        Section 1.7 Voting; Proxies. Unless otherwise provided in the Agreement,
each Securityholder entitled to vote at any meeting of Securityholders shall
have voting power proportionate to the outstanding amount, based on initial
issue price (in the case of Company Common Securities) and liquidation
preference (in the case of Company Preferred Securities), of the Securities held
by such Securityholder that have voting power upon the matter in question. Each
Securityholder entitled to vote at a meeting of Securityholders or to express
consent or dissent to action in writing without a meeting may authorize another
person or persons to act for such Securityholder by proxy, but no such proxy
shall be voted or acted upon after three years from its date, unless the proxy
provides for a longer period. A duly executed proxy shall be irrevocable if it
states that it is irrevocable and if, and only as long as, it is coupled with an
interest sufficient in law to support an irrevocable power, regardless of
whether the interest with which it is coupled is an interest in the Securities
themselves or an interest in the Company generally. A Securityholder may revoke
any proxy which is not irrevocable by attending the meeting and voting in person
or by filing an instrument in writing revoking the proxy or another duly
executed proxy, bearing a later date with the Secretary of the Company. Voting
at meetings of Securityholders need not be by written ballot unless the holders
of a majority of the outstanding Securities entitled to vote thereon present in
person or represented by proxy at such

                                       2
<PAGE>   54
meeting shall so determine. Directors shall be designated, removed and replaced
as provided in the Agreement and Article 2 hereof. Other than in the case of any
matter expressly set forth in the Agreement for which a higher vote may be
required, the affirmative vote of the holders of a majority of the Securities
present in person or represented by proxy at the meeting and entitled to vote on
the subject matter shall be the act of the Securityholders.

        Section 1.8 Fixing Date for Determination of Securityholders of Record.
In order that the Company may determine the Securityholders entitled to notice
of or to vote at any meeting of Securityholders or any adjournment thereof, the
Board of Directors may fix a record date, which record date shall not precede
the date upon which the resolution fixing the record date is adopted by the
Board of Directors, and which record date shall not be more than sixty nor less
than ten days before the date of such meeting. If no record date is fixed by the
Board of Directors, the record date for determining Securityholders entitled to
notice of or to vote at a meeting of Securityholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held. A determination of Securityholders of record entitled
to notice of or to vote at a meeting of Securityholders shall apply to any
adjournment of the meeting; provided, however, that the Board of Directors may
fix a new record date for the adjourned meeting.

        In order that the Company may determine the Securityholders entitled to
consent to action in writing without a meeting, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If no
record date has been fixed by the Board of Directors, the record date for
determining Securityholders entitled to consent to action in writing without a
meeting, when no prior action by the Board of Directors is required by law,
shall be the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the Company by delivery to
(a) its registered office in the State of Delaware, (b) its principal place of
business, or (c) an Officer or agent of the Company having custody of the book
in which proceedings of meetings of Securityholders are recorded. Delivery made
to the Company's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been fixed by
the Board of Directors and prior action by the Board of Directors is required by
law, the record date for determining Securityholders entitled to consent to
action in writing without a meeting shall be at the close of business on the day
on which the Board of Directors adopts the resolution taking such prior action.

        In order that the Company may determine the Securityholders entitled to
receive payment of any distribution or allotment of any rights or the
Securityholders entitled to exercise rights in respect of any exchange of
Securities, or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted, and which record
date shall be not more than sixty days prior to such action. If no record date
is fixed, the record date for determining Securityholders for any such purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto.

        Section 1.9 List of Securityholders Entitled to Vote. The Secretary
shall prepare and make, at least ten days before every meeting of
Securityholders, a complete list of the Securityholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
Securityholder and the amount of Securities registered in the name of each
Securityholder. Such list shall be open to the examination of any
Securityholder, for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten days prior to the meeting, either at a place
within the city where the meeting is to be held, which place shall be specified
in the notice of the meeting, or, if not so specified, at the place where the
meeting is to be held. The list shall also be produced and kept at the time and
place of the meeting during the whole time thereof and may be inspected by any
Securityholder who is present.

        Section 1.10 Consent of Securityholders in Lieu of Meeting. Unless
otherwise provided in the Agreement or by law, any action required by law to be
taken at any annual or special meeting of Securityholders of the Company, or any
action which may be taken at any annual or special meeting of such
Securityholders, may be taken without a meeting, without prior notice and
without a vote, if a consent or consents in writing, setting forth the action so
taken, shall be signed by the holders of outstanding Securities having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all Securities entitled to vote thereon were
present and voted and shall be delivered to the Company by delivery to (a) its
registered office in the State of Delaware by hand or by certified mail or
registered mail, return receipt requested, (b) its principal place of business,
or (c) an Officer or agent of the Company having custody of the book in which
proceedings of meetings of Securityholders are recorded. Every written consent
shall bear the date of signature of each Securityholder who signs the consent
and no written consent shall be effective to take the action referred to therein
unless, within sixty days of the earliest dated consent delivered in the manner
required by this By-Law to the Company, written consents signed by holders
representing a sufficient amount of Securities to take action are delivered to
the Company by delivery to (a) its registered office in the State of Delaware by
hand or by certified or registered mail, return receipt requested, (b) its
principal place of business, or (c) an Officer or agent of the Company having
custody of the book in which proceedings of meetings of Securityholders are
recorded. Prompt notice of the taking of the action without a meeting by less
than unanimous written consent shall be given to those Securityholders who have
not consented in writing.

                                    ARTICLE 2

                               Board of Directors

        Section 2.1 Number; Powers; By-Laws. The business and affairs of the
Company shall be managed by or under the direction of a Board composed of not
less than one nor more than seven Directors. The Board shall manage the business
and affairs of the Company and may exercise all powers in connection therewith,
except for such powers as are required to be exercised by Securityholders, all
in accordance with the Agreement, these By-Laws and applicable law. Except to
the extent that the Board or the Securityholders confer such authority on a
Director, no Director shall have the authority to bind the Company.

                                       4
<PAGE>   56

        Section 2.2 Voting Power. Each Director shall, in the consideration of
any matter by the Board, have a single vote at the time such vote is taken or
made (whether at a meeting or by written consent). Except where a greater
percentage approval may be provided for herein or in the Agreement or by law, an
action shall be deemed approved by the Board only if it has been approved by a
majority of the Directors.

        Section 2.3 Quorum. At all meetings of the Board, the presence of at
least a majority of Directors shall constitute a quorum for the transaction of
business. In case at any meeting of the Board a quorum shall not be present, any
Director present may adjourn the meeting from time to time until a quorum shall
be present.

        Section 2.4 Designation; Removal; Replacement. The term of office of a
Director shall be until the earliest of the following events: (i) his or her
successor is designated or (ii) he or she resigns or is removed. Any Director
may be removed, with or without cause by majority vote of the remaining
Directors. In the event of the resignation, removal or death of a Director, such
Director shall be replaced by another person designated by majority vote of the
remaining Directors. Any Director may resign at any time upon written notice to
the Board of Directors or to the President or the Secretary of the Company. Such
resignation shall take effect at the time specified therein, and unless
otherwise specified therein no acceptance of such resignation shall be necessary
to make it effective.

        Section 2.5 Regular Meetings. Regular meetings of the Board of Directors
may be held at such places, within or without the State of Delaware and outside
of the State of Florida, at such times as the Board may from time to time
determine, and if so determined notice thereof need not be given.

        Section 2.6 Special Meetings. Special meetings of the Board of Directors
may be held at any time or place, either within or without the State of Delaware
and outside of the State of Florida, except in the case of an emergency, in
which case a special meeting may be held within the State of Florida, as may be
stated in the notice of the meeting, whenever called by the Chairman of the
Board, by the President or by any two Directors. Reasonable notice thereof shall
be given by the person or persons calling the meeting.

        Section 2.7 Participation in Meetings by Conference Telephone Permitted.
Unless otherwise restricted by the Agreement or these By-Laws, the Board of
Directors, or any committee designated by the Board, may participate in a
meeting of the Board or of such committee, as the case may be, by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and participation in a
meeting pursuant to this By-Law shall constitute presence in person at such
meeting.

        Section 2.8 Organization. Meetings of the Board of Directors shall be
presided over by the Chairman of the Board, or in the absence of the Chairman of
the Board by the President, or in their absence, by a chairman chosen at the
meeting. The Secretary, or in the absence of the Secretary, an Assistant
Secretary, shall act as secretary of the meeting, but in the absence of the
Secretary and any Assistant Secretary, the chairman of the meeting may appoint
any person to act as secretary of the meeting.

        Section 2.9 Action by Directors Without a Meeting. Unless otherwise
restricted by the Agreement or these By-Laws, any action required or permitted
to be taken at any meeting of the Board of Directors, or of any committee
thereof, may be taken without a meeting if all of the Board or of such
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board or committee.

                                    ARTICLE 3

                                   Committees

        Section 3.1 Committees. The Board of Directors may, by resolution of the
Board adopted by majority vote, designate one or more committees, each committee
to consist of one or more of the Directors of the Company. Any such committee,
to the extent provided in the resolution of the Board of Directors or in these
By-Laws, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the Company, and
may authorize the seal of the Company to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to amending the Certificate of Formation, adopting an agreement of merger,
consolidation or conversion, recommending to the Securityholders the sale, lease
or exchange of all or substantially all of the Company's property and assets,
recommending to the Securityholders a dissolution of the Company or a revocation
of a dissolution or amending these By-Laws; and, unless the resolution, these
By-Laws or the Agreement expressly so provides, no such committee shall have the
power or authority to authorize the issuance of Securities, to adopt a
certificate of ownership and merger, consolidation or conversion or to remove or
indemnify Officers or Directors.

        Section 3.2 Committee Rules. Unless the Board of Directors otherwise
provides, each committee designated by the Board may adopt, amend and repeal
rules for the conduct of its business. In the absence of a provision by the
Board or a provision in the rules of such committee to the contrary, a majority
of the members of such committee shall constitute a quorum for the transaction
of business, the vote of a majority of the members present at a meeting at the
time of such vote if a quorum is then present shall be the act of such
committee, and in other respects each committee shall conduct its business in
the same manner as the Board conducts its business pursuant to Article 2 of
these By-Laws.

                                    ARTICLE 4

                                    Officers

        Section 4.1 Officers; Election. As soon as practicable after the annual
meeting of Securityholders in each year, the Board of Directors shall elect a
President and a Secretary, and may also elect one or more Vice Presidents, one
or more Assistant Vice Presidents, one or more Assistant Secretaries, a
Treasurer and one or more Assistant Treasurers and such other Officers as the
Board may deem desirable or appropriate and may give any of them such further
designations or alternate titles as it considers desirable. Any number of
offices may be held by the same person unless the Agreement or these By-Laws
otherwise provide.

        Section 4.2 Term of Office; Resignation; Removal; Vacancies. Unless
otherwise provided in the resolution of the Board of Directors electing any
Officer, each Officer shall hold

                                       6
<PAGE>   58

office until his or her successor is elected and qualified or until his or her
earlier resignation or removal. Any Officer may resign at any time upon written
notice to the Board or to the President or the Secretary of the Company. Such
resignation shall take effect at the time specified therein, and unless
otherwise specified therein no acceptance of such resignation shall be necessary
to make it effective. The Board may remove any Officer with or without cause at
any time. Any such removal shall be without prejudice to the contractual rights
of such Officer, if any, with the Company, but the election of an Officer shall
not of itself create contractual rights. Any vacancy occurring in any office of
the Company by death, resignation, removal or otherwise may be filled by the
Board at any regular or special meeting.

        Section 4.3 Powers and Duties. The Officers of the Company shall have
such powers and duties in the management of the Company as shall be stated in
these By-Laws or in a resolution of the Board of Directors which is not
inconsistent with these By-Laws and, to the extent not so stated, as generally
pertain to comparable offices in a corporation organized under the General
Corporation Law of the State of Delaware, subject to the control of the Board.
The Secretary shall have the duty to record the proceedings of the meetings of
the Securityholders, the Board of Directors and any committees in a book to be
kept for that purpose. The Board may require any Officer, agent or employee to
give security for the faithful performance of his or her duties.

                                    ARTICLE 5

                                   Securities

        Section 5.1 Certificates for Securities. The Securities shall be
registered in certificated form. If such certificate is manually countersigned
by a transfer agent or by a registrar, any other signature on the certificate
may be a facsimile. In case any Officer who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such
Officer before such certificate is issued, it may be issued by the Company with
the same effect as if such person were such Officer at the date of issue.

                                    ARTICLE 6

                                  Miscellaneous

        Section 6.1 Seal. The Company may have a company seal which shall have
the name of the Company inscribed thereon and shall be in such form as may be
approved from time to time by the Board of Directors. The company seal may be
used by causing it or a facsimile thereof to be impressed or affixed or in any
other manner reproduced.

        Section 6.2 Waiver of Notice of Meetings of Securityholders, Directors
and Committees. Whenever notice is required to be given by law or under any
provision of the Agreement or these By-Laws, a written waiver thereof, signed by
the person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to notice. Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends a
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the

                                       7
<PAGE>   59

Securityholders, Directors or a committee of Directors need be specified in any
written waiver of notice unless so required by the Agreement or these By-Laws.

        Section 6.3 Indemnification of Directors, Officers and Employees. The
Company shall indemnify to the full extent permitted under the Delaware Act any
person made or threatened to be made a party to any action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that such person or such person's testator or intestate is or was a Director,
Officer or employee of the Company or serves or served at the request of the
Company any other enterprise as a Director, director, officer or employee except
for such Director's or Officer's gross negligence or willful misconduct.
Expenses, including reasonable attorneys' fees, incurred by any such person in
defending any such action, suit or proceeding shall be paid or reimbursed by the
Company promptly upon receipt by it of an undertaking of such person to repay
such expenses if it shall ultimately be determined that such person is not
entitled to be indemnified by the Company. The rights provided to any person by
this By-Law shall be enforceable against the Company by such person who shall be
presumed to have relied upon it in serving or continuing to serve as a Director,
Officer or employee as provided above. No amendment of this By-Law shall impair
the rights of any person arising at any time with respect to events occurring
prior to such amendment. For purposes of this By-Law, the term "Company" shall
include any predecessor of the Company and any constituent company (including
any constituent of a constituent) absorbed by the Company in a consolidation or
merger; the term "other enterprise" shall include any limited liability company,
corporation, partnership, joint venture, trust or employee benefit plan; service
"at the request of the Company" shall include service as a Director, Officer or
employee of the Company which imposes duties on, or involves services by, such
Director, Officer or employee with respect to an employee benefit plan, its
participants or beneficiaries; any excise taxes assessed on a person with
respect to an employee benefit plan shall be deemed to be indemnifiable
expenses; and action by a person with respect to an employee benefit plan which
such person reasonably believes to be in the interest of the participants and
beneficiaries of such plan shall be deemed to be action not opposed to the best
interests of the Company. The rights conferred on any Person by this Section 6.3
shall not be exclusive of any other rights which such Person may have or
hereafter acquire under any statute, provision of these By-Laws, the Agreement,
any other agreement, vote of Securityholders or disinterested Directors or
otherwise. The Company's obligation, if any, to indemnify any Person who was or
is serving at its request as a director, officer, employee or agent of any other
enterprise shall be reduced by any amount such Person may collect as
indemnification from such other enterprise. Any repeal or modification of the
foregoing provisions of this Section 6.4 shall not adversely affect any right of
protection hereunder of any Person in respect of any act or omission occurring
prior to the time of such repeal or modification.

        Section 6.4 Interested Directors; Quorum. No contract or transaction
between the Company and one or more of its Directors or Officers, or between the
Company and any other limited liability company, corporation, partnership,
association or other organization in which one or more of its Directors or
Officers are Directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because the Director or Officer is
present at or participates in the meeting of the Board of Directors or committee
thereof which authorizes the contract or transaction, or solely because his or
her or their votes are counted for such purpose, if: (1) the material facts as
to his or her relationship or interest and as to the

                                       8
<PAGE>   60

contract or transaction are disclosed or are known to the Board or the
committee, and the Board or committee in good faith authorizes the contract or
transaction by the affirmative votes of disinterested Directors, even though the
disinterested Directors be less than a quorum; or (2) the material facts as to
his or her relationship or interest and as to the contract or transaction are
disclosed or are known to the Securityholders entitled to vote thereon, and the
contract or transaction is specifically approved in good faith by vote of the
Securityholders; or (3) the contract or transaction is fair as to the Company as
of the time it is authorized, approved or ratified, by the Board, a committee
thereof or the Securityholders. Common or interested Directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee which authorizes the contract or transaction.

        Section 6.5 Form of Records. Any records maintained by the Company in
the regular course of its business, including its Securities ledger, books of
account and minute books, shall be kept separate and apart from any records of
TECO, and may be kept on, or be in the form of, punch cards, magnetic tape or
disk, photographs, microphotographs or any other information storage device,
provided that the records so kept can be converted into clearly legible form
within a reasonable time. The Company shall so convert any records so kept upon
the request of any person entitled to inspect the same.

        Section 6.6 Amendment of By-Laws. These By-Laws may be amended or
repealed, and new by-laws adopted, by the Board of Directors in accordance with
the Agreement.

        as Successor Guarantee Trustee. The right, title and interest of the
        Guarantee Trustee shall automatically vest in any Successor Guarantee
        Trustee, upon acceptance by such Successor Guarantee Trustee of its
        appointment hereunder, 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 Guarantee
        Trustee.

                (b)     If an Event of Default has occurred and is continuing,
        the Guarantee Trustee shall enforce this Guarantee Agreement for the
        benefit of the Holders of the Company Preferred Securities.

                (c)     The Guarantee Trustee, before the occurrence of any
        Event of Default and after the curing or waiver of all Events of Default
        that may have occurred, shall undertake to perform only such duties as
        are specifically set forth in this Guarantee Agreement, and no implied
        covenants shall be read into this Guarantee Agreement against the
        Guarantee

                                        6

        Trustee. In case an Event of Default has occurred (that has not been
        cured or waived pursuant to Section 2.6), the Guarantee Trustee shall
        exercise such of the rights and powers vested in it by this Guarantee
        Agreement, 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 Guarantee Agreement shall be
        construed to relieve the 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
                        Guarantee Trustee shall be determined solely by the
                        express provisions of this Guarantee Agreement, and the
                        Guarantee Trustee shall not be liable except for the
                        performance of such duties and obligations as are
                        specifically set forth in this Guarantee Agreement; and

                                (B)     in the absence of bad faith on the part
                        of the Guarantee Trustee, the 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 Guarantee
                        Trustee and conforming to the requirements of this
                        Guarantee Agreement; but in the case of any such
                        certificates or opinions that by any provision hereof or
                        of the Trust Indenture Act are specifically required to
                        be furnished to the Guarantee Trustee, the Guarantee
                        Trustee shall be under a duty to examine the same to
                        determine whether or not they conform to the
                        requirements of this Guarantee Agreement;

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

                        (iii)   the 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 preference of the Company Preferred Securities
        relating to the time, method and place of conducting any proceeding for
        any remedy available to the Guarantee Trustee, or exercising any trust
        or power conferred upon the Guarantee Trustee under this Guarantee
        Agreement; and

                        (iv)    no provision of this Guarantee Agreement shall
        require the 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
        Guarantee Trustee shall have reasonable grounds for

                                        7

<PAGE>   11

        believing that the repayment of such funds or liability is not
        reasonably assured to it under the terms of this Guarantee Agreement or
        adequate indemnity against such risk or liability is not reasonably
        assured to it.

        SECTION 3.2 CERTAIN RIGHTS OF GUARANTEE TRUSTEE.

        (a)     Subject to the provisions of Section 3.1:

                (i)     The Guarantee Trustee may conclusively rely and shall be
        fully protected in acting or refraining from acting upon any resolution,
        certificate, statement, instrument, opinion, report, notice, request,
        direction, consent, order, bond, debenture, note, other evidence of
        indebtedness or other paper or document reasonably believed by it to be
        genuine and to have been signed, sent or presented by the proper party
        or parties.

                (ii)    Any direction or act of the Guarantor contemplated by
        this Guarantee Agreement shall be sufficiently evidenced by an Officer's
        Certificate unless otherwise prescribed herein.

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

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

                (v)     The Guarantee Trustee shall be under no obligation to
        exercise any of the rights or powers vested in it by this Guarantee
        Agreement at the request or direction of any Holder, unless such Holder
        shall have provided to the Guarantee Trustee such adequate security and
        indemnity as would satisfy a reasonable person in the position of the
        Guarantee Trustee, against the costs, expenses (including attorneys'
        fees and expenses) 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 Guarantee Trustee; provided that,
        nothing contained in this Section 3.2(a)(v) shall be taken to relieve
        the Guarantee Trustee, upon the

                                        8

<PAGE>   12

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

                (vi)    The 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 Guarantee Trustee, in
        its discretion, may make such further inquiry or investigation into such
        facts or matters as it may see fit, and if the Guarantee Trustee shall
        determine to make such further inquiry or investigation, it shall be
        entitled to examine the books, records and premises of the Guarantor,
        personally or by agent or attorney.

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

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

                (ix)    Whenever in the administration of this Guarantee
        Agreement the Guarantee Trustee shall deem it desirable to receive
        instructions with respect to enforcing any remedy or right or taking any
        other action hereunder, the Guarantee Trustee (A) may request
        instructions from the Holders of a Majority in Liquidation Amount of the
        Company Preferred Securities, (B) may refrain from enforcing such remedy
        or right or taking such other action until such instructions are
        received, and (C) shall be protected in acting in accordance with such
        instructions.

        (b)     No provision of this Guarantee Agreement shall be deemed to
impose any duty or obligation on the 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 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 Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

        The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold
it harmless against, any loss, liability or expense incurred without negligence
or bad faith on the part of the Guarantee Trustee, arising out of or in
connection with the acceptance or administration of this Guarantee Agreement,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder. The Guarantee Trustee will not claim or exact any lien or
charge on any Guarantee Payments as a result of any amount due to it under this
Guarantee Agreement.

        SECTION 4.1    GUARANTEE TRUSTEE: ELIGIBILITY.

                (a)     There shall at all times be a Guarantee Trustee which

                Trust Indenture Act to act as such and has a combined capital
                and surplus of at least $50,000,000, and shall be a corporation
                meeting the requirements of Section 310(c) of the Trust
                Indenture Act. If such corporation publishes reports of
                condition at least annually, pursuant to law or to the
                requirements of the supervising or examining authority, then,
                for the purposes of this Section and to the extent permitted by
                the Trust Indenture Act, 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 Guarantee Trustee shall cease to be

        immediately resign in the manner and with the effect set out in Section
        4.2(c).

                (c)     If the Guarantee Trustee has or shall acquire any
        "conflicting interest" within the meaning of Section 310(b) of the Trust
        Indenture Act, the 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 THE GUARANTEE
        TRUSTEE.

                (a)     Subject to Section 4.2(b), the Guarantee Trustee may be
        appointed or removed without cause at any time by the Guarantor.

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

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

                (d)     If no Successor 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 Guarantee Trustee may petition, at the
        expense of the Guarantor, any court of competent jurisdiction for
        appointment of a Successor Guarantee Trustee. Such court may thereupon,
        after prescribing such notice, if any, as it may deem proper, appoint a
        Successor Guarantee Trustee.

        The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders of the Company Preferred Securities the Guarantee Payments (without
duplication of amounts theretofore paid by or on behalf of the LLC), as and when
due, regardless of any defense, right of setoff or counterclaim which the LLC
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 of the Company Preferred Securities or by causing the LLC to pay such
amounts to the Holders.

        SECTION 5.2 WAIVER OF NOTICE AND DEMAND.

        The Guarantor hereby waives notice of acceptance of the Guarantee
Agreement and of any liability to which it applies or may apply, presentment,

        SECTION 5.3 OBLIGATIONS NOT AFFECTED.

        of the performance or observance by the LLC of any express or implied
        agreement, covenant, term or condition relating to the Company Preferred
        Securities to be performed or observed by the LLC;

                                       11

<PAGE>   15

                (b)     the extension of time for the payment by the LLC of all

        Price, Liquidation Distribution or any other sums payable under the

        Company Preferred Securities, or any action on the part of the LLC
        granting indulgence or extension of any kind;

                (d)     the voluntary or involuntary liquidation, dissolution,
        sale of any collateral, receivership, insolvency, bankruptcy, assignment
        for the benefit of creditors, reorganization, arrangement, composition
        or readjustment of debt of, or other similar proceedings affecting, the

        Company Preferred 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
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

        SECTION 5.4 RIGHTS OF HOLDERS.

Agreement; and (iv) to the fullest extent permitted by law, without the need for
any other action of any person, including the Guarantee Trustee or any other
Holder of Trust Preferred Securities or Company Preferred Securities, each

Securities under this Guarantee Agreement. The Guarantor waives, any right or
remedy to require that any action on this Guarantee Agreement be

brought first against the LLC or any other Person or entity before proceeding
directly against the Guarantor.

        SECTION 5.5 GUARANTEE OF PAYMENT.

        This Guarantee Agreement creates a guarantee of payment and not of
collection. This Guarantee Agreement will not be discharged except by payment of
the Guarantee Payments in full (without duplication of amounts theretofore paid
by the LLC) or upon distribution of Notes to Holders as provided in the LLC
Agreement and the Trust Agreement.

        SECTION 5.6 SUBROGATION.

        The Guarantor shall be subrogated to all (if any) rights of the Holders
against the LLC in respect of any amounts paid to the Holders by the Guarantor
under this Guarantee Agreement and shall have the right to waive payment by the
LLC pursuant to Section 5.1; provided, however, that the Guarantor shall not
(except to the extent required by mandatory provisions of law) be entitled to
enforce or exercise any rights which it may acquire by way of subrogation or any
indemnity, reimbursement or other agreement, in all cases as a result of payment
under this Guarantee Agreement, if at the time of any such payment, any amounts
are due and unpaid under this Guarantee Agreement. If any amount shall be paid

hold such amount in trust for the Holders of the Company Preferred Securities
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 LLC with respect to the Company Preferred
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.

        SECTION 6.1 [UNSECURED OBLIGATION][ SUBORDINATION].

        This Guarantee Agreement will constitute an unsecured obligation of the
Guarantor [and will rank subordinate and junior in right of payment to all
Senior Indebtedness and Subordinated Indebtedness of the Guarantor.]

        SECTION 6.2 PARI PASSU GUARANTEES.

        This Guarantee Agreement shall rank pari passu with any similar
Guarantee Agreements issued by the Guarantor on behalf of the Holders of Company
Preferred Securities issued by the LLC.

        This Guarantee Agreement shall terminate and be of no further force and
effect upon (i) full payment of the Redemption Price of all Company Preferred
Securities, (ii) the distribution of Notes to the Holders in exchange for all of
the Company Preferred Securities or (iii) full payment of the amounts payable in
accordance with the Trust Agreement upon liquidation of the LLC, provided,
however, that the provisions of Section 3.3 hereof shall survive the termination
of this Guarantee Agreement. Notwithstanding the foregoing, this Guarantee
Agreement will continue to be effective or will be reinstated, as the case may
be, if at any time any Holder must restore payment of any sums paid with respect
to Company Preferred Securities or this Guarantee Agreement.

                                  ARTICLE VIII

                                  MISCELLANEOUS

Preferred Securities then outstanding. Except in connection with a
consolidation, merger or sale involving the Guarantor that is permitted under
Article Eight of the Indenture and pursuant to which the assignee agrees in
writing to perform the Guarantor's obligations hereunder, the Guarantor shall
not assign its obligations hereunder.
