Shelf Registration Statement in accordance with the provisions of Section 2(a)
in lieu of conducting an Exchange Offer in accordance with the foregoing
sentence, the Company may, if permitted in accordance with then applicable
regulations and the then current interpretations of the staff of the Commission,
elect to conduct an Exchange Offer in accordance with the terms set forth
herein, other than with respect to the specific timing requirements set forth in
the foregoing sentence. In the event the Company consummates an Exchange Offer
subsequent to the filing and effectiveness of a Shelf Registration Statement,
the Company's obligations to maintain such a Shelf Registration shall terminate
except for Private Exchange Securities (as defined below). Upon the
effectiveness of the Exchange Offer Registration Statement, the Company and the
Trust shall promptly commence the Exchange Offer, it being the objective of such
Exchange Offer to enable each Holder eligible and electing to exchange
Registrable Securities for a like principal amount of Exchange Debentures or a
like liquidation amount of Exchange Capital Securities, together with the
Exchange Guarantee, as applicable (assuming that such Holder (i) is not an
affiliate of the Company or the Trust within the meaning of Rule 405 under the
Securities Act, (ii) is not a broker-dealer tendering Registrable Securities
acquired directly from the Company for its own account, (iii) acquires the
Exchange Securities in the ordinary course of such Holder's business, and (iv)
has no arrangements or understandings with any Person to participate in the
Exchange Offer for the purpose of distributing the Exchange Securities) to
transfer such Exchange Securities from and after their receipt without any
limitations or restrictions under the Securities Act and under state securities
or blue sky laws.

           In connection with the Exchange Offer, the Company and the Trust
shall:

     (i)   mail to each Holder a copy of the Prospectus forming part of the
Exchange Offer Registration Statement, together with an appropriate letter of
transmittal and related documents;

 
     (ii)  keep the Exchange Offer open for acceptance for a period of not less
than 30 days after the date notice thereof is mailed to

                                       7

the Holders (or longer if required by applicable law) (such period referred to
herein as the "Exchange Period");
               ---------------   

     (iii) utilize the services of the Depositary for the Exchange Offer;

     (iv)  permit Holders to withdraw tendered Securities at any time prior to
the close of business, New York time, on the last Business Day of the Exchange
Period, by sending to the institution specified in the notice, a telegram,
telex, facsimile transmission or letter setting forth the name of such Holder,
the principal amount of Securities delivered for exchange, and a statement that
such Holder is withdrawing his election to have such Securities exchanged;

     (v)   notify each Holder that any Security not tendered by such Holder in
the Exchange Offer will remain outstanding and continue to accrue interest or
accumulate distributions, as the case may be, but will not retain any rights
under this Agreement (except in the case of the Initial Purchaser and
Participating Broker-Dealers as provided herein); and

     (vi)  otherwise comply in all respects with all applicable laws relating to
the Exchange Offer.

           If the Initial Purchaser determines upon advice of its outside
counsel that it is not eligible to participate in the Exchange Offer with
respect to the exchange of Securities constituting any portion of an unsold
allotment in the initial distribution as soon as practicable upon receipt by the
Company and the Trust of a written request from the Initial Purchaser, the
Company and the Trust, as applicable, shall issue and deliver to such Initial
Purchaser in exchange (the "Private Exchange") for the Securities held by the
                            ----------------
Initial Purchaser, a like liquidation amount of Capital Securities of the Trust,
together with the Exchange Guarantee, or a like principal amount of the
Subordinated Debentures of the Company, as applicable, that are identical
(except that such securities may bear a customary legend with respect to
restrictions on transfer pursuant to the Securities Act) to the Exchange
Securities (the "Private Exchange Securities") and which are issued pursuant to
                 ---------------------------                                   
the Indenture, the Declaration or the Guarantee (which provides that the
Exchange Securities will not be subject to the transfer restrictions set forth
in the Indenture or the Declaration, as applicable, and that the Exchange
Securities, the Private Exchange Securities and the Securities will vote and
consent together on all matters as one class and that neither the Exchange
Securities, the Private Exchange Securities nor the Securities will have the
right to vote or consent as a separate class on any matter). The Private
Exchange Securities shall be of the same series as the Exchange Securities and
the Company and the Trust will seek to cause the CUSIP Service Bureau to issue
the same

CUSIP Numbers for the Private Exchange Securities as for the Exchange Securities
issued pursuant to the Exchange Offer.

           As soon as practicable after the close of the Exchange Offer and, if
applicable, the Private Exchange, the Company and the Trust, as the case
requires, shall:

     (i)   accept for exchange all Securities or portions thereof tendered and
not validly withdrawn pursuant to the Exchange Offer or the Private Exchange;

     (ii)  deliver, or cause to be delivered, to the applicable Trustee for
cancellation all Securities or portions thereof so accepted for exchange by the
Company; and

     (iii) issue, and cause the applicable Trustee under the Indenture, the
Declaration or the Guarantee, as applicable, to promptly authenticate and
deliver to each Holder, new Exchange Securities or Private Exchange Securities,
as applicable, equal in principal amount to the principal amount of the
Subordinated Debentures or equal in liquidation amount to the liquidation amount
to the Capital Securities (together with the guarantee thereof) as are
surrendered by such Holder.

           Distributions on each Exchange Capital Security and interest on each
Exchange Debenture and Private Exchange Security issued pursuant to the
Registered Exchange Offer and in the Private Exchange will accrue from the last
date on which a Distribution or interest was paid on the Capital Security or the
Subordinated Debenture surrendered in exchange therefore or, if no Distribution
or interest has been paid on such Capital Security or Subordinated Debenture,
from the Issue Date. To the extent not prohibited by any law or applicable
interpretation of the staff of the SEC, the Company and the Trust shall use
their best efforts to complete the Exchange Offer, if commenced, as provided
above, and shall comply with the applicable requirements of the Securities Act,
the Exchange Act and other applicable laws in connection with the Exchange
Offer. The Exchange Offer shall not be subject to any conditions, other than (i)
that the Exchange Offer or the making of any exchange by a Holder does not
violate applicable law or any applicable interpretation of the staff of the SEC;
(ii) due tendering of the Registrable Securities in accordance with the Exchange
Offer; (iii) that each Holder of Registrable Securities to be exchanged in the
Exchange Offer shall make the customary representations set forth in the next
sentence of this paragraph and (iv) that no action or proceeding shall have been
instituted or threatened in any court or by or before any governmental agency
with respect to the Exchange Offer which, in the Company's judgment, could
reasonably be expected to impair the ability of the Company to proceed with the
Exchange Offer. Each Holder of Registrable Securities who wishes to exchange
such Registrable Securities for Exchange Securities in the Exchange Offer will
be

                                       9
<PAGE>
 
required to make certain customary representations in connection therewith,
including, in the case of any Holder of Capital Securities, representations that
(i) it is not an affiliate of the Trust or the Company, (ii) the Exchange
Securities to be received by it were acquired in the ordinary course of its
business, (iii) at the time of the Exchange Offer, it has no arrangement with
any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Capital Securities and (iv) such other
representations as may be reasonably necessary under applicable rules and
regulations to render the use of Form S-4 or other appropriate form under the
Securities Act available. The Company and the Trust shall inform the Initial
Purchaser, after consultation with the Trustee, of the names and addresses of
the Holders to whom the Exchange Offer is made, and the Initial Purchaser shall
have the right to contact such Holders and otherwise facilitate the tender of
Registrable Securities in the Exchange Offer.

           Upon consummation of the Exchange Offer in accordance with this
Section 2(b), the provisions of this Agreement shall continue to apply, mutatis
                                                                        -------

Exchange Securities and Exchange Securities held by Participating 
Broker-Dealers, and the Company and the Trust shall have no further obligation
to register the Registrable Securities (other than Private Exchange Securities)
pursuant to Section 2(a) of this Agreement.

           (c)   Expenses.  The Company shall pay all Registration Expenses in
                 --------                                                     
connection with the registration pursuant to Section 2(a) or 2(b) hereof and
will reimburse the Initial Purchaser for the reasonable fees and disbursements
of Brown & Wood LLP, counsel for the Initial Purchaser, incurred in connection
with the Exchange Offer and, if applicable, the Private Exchange Offer, and
either Brown & Wood LLP or any one other counsel designated in writing by the
Majority Holders to act as counsel for the Holders of the Registrable Securities
in connection with a Shelf Registration Statement, which other counsel shall be
reasonably satisfactory to the Company. Except as provided herein, each Holder
shall pay all expenses of its counsel, underwriting discounts and commissions
and transfer taxes, if any, relating to the sale or disposition of such Holder's
Registrable Securities pursuant to the Shelf Registration Statement and the
Exchange Offer, if any; provided, however that the Company shall pay any
transfer taxes with respect to any Exchange Offer.

           (d)   Effective Registration Statement.  A Shelf Registration
                 --------------------------------                        
Statement pursuant to Section 2(a) hereof or an Exchange Offer Registration
Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC; provided, however,

order, injunction or other order or requirement of the SEC or any other
governmental agency or court, such Registration Statement will be deemed not to
have been effective during the period of such interference, until the offering
of Registrable Securities pursuant to such Registration Statement may legally
resume. The Company and the Trust will be deemed not to have used their best
efforts to cause the Shelf Registration Statement or the Exchange Offer
Registration Statement, as the case may be, to become, or to remain, effective
during the requisite period if either of them voluntarily take any action that
would result in any such registration Statement not being declared effective or
in the Holders of Registrable Securities covered thereby not being able to
exchange or offer and sell such Registrable Securities during that period unless
such action is required by applicable law.

           (e)   Liquidated Damages.  In the event that (i) neither the Shelf

     (ii)  neither the Shelf Registration Statement nor an Exchange Offer
Registration Statement is declared effective by the SEC on or prior to the 30th
day after the applicable required filing date, then, commencing on the 31st day
after the applicable required filing date, additional interest shall accrue on
the principal amount of the Subordinated Debentures, and additional
distributions shall accumulate on the liquidation amount of the Capital
Securities each at a rate of 0.25% per annum; or

     (iii) (A) the Shelf Registration Statement has been declared effective and

the expiration of the Rule 144(k) Period (other than (a) after such time as all
Capital Securities have been disposed of thereunder or otherwise cease to be
Registrable Securities or (b) if the Company effects an Exchange Offer and
is no longer obligated to maintain the effectiveness of the Shelf Registration
Statement) or (B) if applicable, the Trust has not exchanged Exchange Capital
Securities for all Capital Securities or the Company has not exchanged Exchange
Guarantees or Exchange Subordinated Debentures for all Guarantees or
Subordinated Debentures validly tendered, in accordance with the terms of the
Exchange Offer on or prior to the 45th day after the date on which the Exchange
Offer Registration Statement was declared effective, then additional interest
shall accrue on the principal amount of Subordinated Debentures, and additional
distributions shall accumulate on the liquidation amount of the Capital
Securities, each at a rate of 0.25% per annum commencing on (x) the day the
Shelf Registration Statement ceases to be effective in the case of

above;

provided, however, that neither the additional interest rate on the Subordinated
Debentures, nor the additional distribution rate on the liquidation amount of
the Capital Securities, may exceed in the aggregate 0.25% per annum; provided,
further, however, that (1) upon the filing of the Shelf Registration Statement
or an Exchange Offer Registration Statement (in the case of clause (i) above),
(2) upon the effectiveness of the Shelf Registration Statement or an Exchange
Offer Registration Statement (in the case of clause (ii) above), or (3) upon the
effectiveness of the Shelf Registration Statement which had ceased to remain
effective (in the case of clause (iii)(A) above) or upon the exchange of
Exchange Capital Securities, Exchange Guarantees and Exchange Subordinated
Debentures for all Capital Securities, Guarantees and Subordinated Debentures

of the Capital Securities as a result of such clause (or the relevant subclause
thereof), as the case may be, shall cease to accrue or accumulate, as the case

     Any amounts of additional interest and additional Distributions due
pursuant to Section 2(e)(i), (ii) or (iii) above ("Liquidated Damages") will be
payable in cash on the next succeeding February 1 or August 1 , as the case may
be, to holders on the relevant record dates for the payment of interest and
Distributions pursuant to the Indenture and the Declaration, respectively.

           (f)   Specific Enforcement.  Without limiting the remedies

available to the Holders, the Company and the Trust acknowledge that any failure
by the Company or the Trust to comply with its obligations under Section 2(a)
and Section 2(b) hereof may result in material irreparable injury to the Holders
for which there is no adequate remedy at law, that it would not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, any Holder may obtain such relief as may be required to specifically
enforce the Company's and the Trust's obligations under Section 2(a) and Section
2(b) hereof.

           3.    Registration Procedures.  In connection with the obligations of

     Statement, (ii) the release of such Records is ordered pursuant to a
     subpoena or other order from a court of competent jurisdiction or is

     Exchange Securities to be received by such broker-dealer in the Exchange
     Offer, whether such positions or policies have been publicly disseminated
     by the staff of the SEC or such positions or policies, in the reasonable
     judgment of the Initial Purchaser or such other representative, represent
     the prevailing views of the staff of the SEC, including a statement that
     any such broker-dealer who receives Exchange Securities for Registrable
     Securities pursuant to the Exchange Offer may be deemed a statutory
     underwriter and must deliver a prospectus meeting the requirements of the
     Securities Act in connection with any resale of such Exchange Securities,
     (ii) furnish to each Participating Broker-Dealer who has delivered to the
     Company the notice referred to in Section 3(e), without charge, as many
     copies of each Prospectus included in the Exchange Offer Registration

     contained therein in order to permit such Prospectus to be lawfully
     delivered by all Persons subject to the prospectus delivery requirements of

          Securities acquired for its own account as a result of market-making
          activities or other trading activities, it will deliver a prospectus
          meeting the requirements of the Securities Act in connection with any
          resale of Exchange Securities received in respect of such Registrable
          Securities pursuant to the Exchange Offer";

          and (y) a statement to the effect that by a broker-dealer making the
     acknowledgment described in clause (x) and by delivering a Prospectus in
     connection with the exchange of Registrable Securities, the broker-dealer
     will not be deemed to admit that it is an underwriter within the meaning of
     the Securities Act; and

          (B) in the case of any Exchange Offer Registration Statement, the
     Company and the Trust agree to deliver to the Initial Purchaser or to
     another representative of the Participating Broker-Dealers, if requested
     by the Initial Purchaser or such other representative of the Participating
     Broker-Dealers, on behalf of the Participating Broker-Dealers upon
     consummation of the Exchange Offer (i) an opinion of counsel in form and
     substance reasonably satisfactory to the Initial Purchaser or such other
     representative of the Participating Broker-Dealers, covering the matters
     customarily covered in opinions requested in connection with Exchange Offer
     Registration Statements and such other matters as may be reasonably
     requested (it being agreed that the matters to be covered by such opinion
     may be subject to customary qualifications and exceptions), (ii) an
     officers' certificate containing certifications substantially similar to
     those set forth in Section 5(f) of the Purchase Agreement and such
     additional certifications as are customarily delivered in a public

     the Exchange Offer Registration Statement, a comfort letter, in each case,
     in customary form if permitted by Statement on Auditing Standards No. 72.

          The Company or the Trust may require each seller of Registrable
Securities as to which any registration is being effected to furnish to the
Company or the Trust, as applicable, such information regarding such seller as
may be required by the

                                      21
<PAGE>
 
staff of the SEC to be included in a Registration Statement.  The Company or the
Trust may exclude from such registration the Registrable Securities of any
seller who fails to furnish such information within a reasonable time after
receiving such request.  The Company shall have no obligation to register under
the Securities Act the Registrable Securities of a seller who so fails to
furnish such information.

          In the case of (1) a Shelf Registration Statement or (2) Participating
Broker-Dealers who have notified the Company and the Trust that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in Section 3(t) hereof, are seeking to sell Exchange Securities and
are required to deliver Prospectuses each Holder agrees that, upon receipt of
any notice (the "Notice") from the Company or the Trust of the happening of any
                 ------                                                        
event of the kind described in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi)
hereof, such Holder will forthwith discontinue disposition of Registrable
Securities pursuant to a Registration Statement until such Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
3(i) hereof or until it is advised in writing (the "Advice") by the Company and
                                                    ------                     
the Trust that the use of the applicable Prospectus may be resumed, and, if so
directed by the Company and the Trust, such Holder will deliver to the Company
or the Trust (at the Company's or the Trust's expense, as the case requires) all
copies in such Holder's possession, other than permanent file copies then in
such Holder's possession, of the Prospectus covering such Registrable Securities
or Exchange Securities, as the case may be, current at the time of receipt of
such notice.  If the Company or the Trust shall give any such notice to suspend
the disposition of Registrable Securities or Exchange Securities, as the case
may be, pursuant to a Registration Statement, the Company and the Trust shall
use their best efforts to file and have declared effective (if an amendment) as
soon as practicable an amendment or supplement to the Registration Statement
provided, however, that the Company and the Trust may delay the filing of an
amendment or supplement to the Registration Statement in good faith and for a
valid corporate purpose for a period not to exceed 120 days, such right to be
exercisable only once in any 365 day period; provided, further, however, that
the Company and the Trust shall provide each Holder with written notice of their
intention to effect such delay and written notice of the date on which such
supplement, post-effective amendment or other document has been filed with the
SEC or declared effective, as the case may be.  The Company and the Trust shall
extend the period during which such Registration Statement shall be maintained
effective pursuant to this Agreement by the number of days in the period from
and including the date of the giving of the Notice to and including the date
when the Company and the Trust shall have made available to the Holders (x)
copies of the supplemented or amended Prospectus necessary to resume such
dispositions or (y) the Advice.

              --------------------------------                             
Registration Statement, the Company and the Trust shall, jointly and severally,
indemnify and hold harmless the Initial Purchaser, each Holder, each underwriter
who participates in an offering of the Registrable Securities, each
Participating Broker-Dealer, each Person, if any, who controls any of such
parties within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act and each of their respective directors, officers, employees and
agents, as follows:

          (i)  from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, arising out of any
     untrue statement or alleged untrue statement of a material fact contained
     in any Registration Statement (or any amendment thereto), covering
     Registrable Securities or Exchange Securities, including all documents
     incorporated therein by reference, or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     Prospectus (or any amendment or supplement thereto) or the omission or
     alleged omission therefrom of a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading;

          (ii)  from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, to the extent of the
     aggregate amount paid in  settlement of any litigation, or any
     investigation or proceeding by any court or governmental agency or body,
     commenced or threatened, or of any claim whatsoever based upon any such
     untrue statement or omission, or any such alleged untrue statement or
     omission, if such settlement is effected with the prior written consent of
     the Company; and

          (iii)  from and against any and all expenses whatsoever, as incurred
     (including reasonable fees and disbursements of counsel chosen by such
     Holder, such Participating Broker-Dealer, or any underwriter (except to the
     extent otherwise expressly provided in Section 4(c) hereof)), reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any court or governmental agency or
     body, commenced or threatened, or any claim whatsoever based upon any such
     untrue statement or omission, or any such alleged untrue statement or
     omission, to the extent that any such expense is not paid under
     subparagraph (i) or (ii) of this Section 4(b);

provided, however, that (i) this indemnity does not apply to any loss,
--------  -------                                                     
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or

                                      23
<PAGE>
 
omission made in reliance upon and in conformity with written information
furnished in writing to the Company or the Trust by such Holder, such
Participating Broker-Dealer or any underwriter with respect to such Holder,
Participating Broker-Dealer or any underwriter, as the case may be, expressly
for use in the Registration Statement (or any amendment thereto) or any
Prospectus (or any amendment or supplement thereto) and (ii) with respect to any
preliminary prospectus, this indemnity shall not inure to the benefit of any
Person claiming indemnity hereunder ("Indemnified Person") from whom the person
asserting any such losses, claims, damages or liabilities purchased Registrable
Securities, or any Person controlling such Indemnified Person, if a copy of the
Prospectus (as then amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) was not sent or given by or on behalf of
such Indemnified Person to such person, if such is required by law, at or prior
to the written confirmation of the sale of such shares to such person and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim, damage or liability.  Any amounts advanced by the
Company or the Trust to an indemnified party pursuant to this Section 4 as a
result of such losses shall be returned to the Company or the Trust if it shall
be finally determined by such a court in a judgment not subject to appeal or
final review that such indemnified party was not entitled to indemnification by
the Company or the Trust.

          (b)  Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Trust, any underwriter and the other selling
Holders and each of their respective directors, officers (including each officer
of the Company and the Trust who signed the Registration Statement), employees
and agents and each Person, if any, who controls the Company, the Trust, any
underwriter or any other selling Holder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
loss, liability, claim, damage and expense whatsoever described in the indemnity
contained in Section 4(a) hereof, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or any Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company or the Trust by such selling Holder with
respect to such Holder expressly for use in the Registration Statement (or any
amendment thereto), or any such Prospectus (or any amendment or supplement
thereto); provided, however, that, in the case of the Shelf Registration
          --------  -------                                             
Statement, no such Holder shall be liable for any claims hereunder in excess of
the amount of net proceeds received by such Holder from the sale of Registrable
Securities pursuant to such Shelf Registration Statement.

          (c)  Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in

                                      24
<PAGE>
 
respect of which indemnity may be sought hereunder, enclosing a copy of all
papers properly served on such indemnified party, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
which it may have under this Section 4, except to the extent that it is
materially prejudiced by such failure.  An indemnifying party may participate at
its own expense in the defense of such action.  If an indemnifying party so
elects within a reasonable time after receipt of such notice, an indemnifying
party, severally or jointly with any other indemnifying parties receiving such
notice, may assume the defense of such action with counsel chosen by it and
reasonably acceptable to the indemnified parties defendant in such action,
provided, however, that if (i) representation of such indemnified party by the
--------  -------                                                             
same counsel would present a conflict of interest or (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and any such indemnified party
reasonably determines that there may be legal defenses available to such
indemnified party which are different from or in addition to those available to
such indemnifying party, then in the case of clauses (i) and (ii) of this
Section 4(c) such indemnifying party and counsel for each indemnifying party or
parties shall not be entitled to assume such defense.  If an indemnifying party
is not entitled to assume the defense of such action as a result of the proviso
to the preceding sentence, counsel for such indemnifying party and counsel for
each indemnified party or parties shall be entitled to conduct the defense of
such indemnified party or parties.  If an indemnifying party assumes the defense
of such action, in accordance with and as permitted by the provisions of this
paragraph, such indemnifying parties shall not be liable for any fees and
expenses of counsel for the indemnified parties incurred thereafter in
connection with such action.  In no event shall the indemnifying parties be
liable for the fees and expenses of more than one counsel (in addition to local
counsel), separate from its own counsel, for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 4 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional written release in form and substance satisfactory to
the indemnified parties of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

                                      25

          (d)  Notwithstanding the last sentence of Section 4(c), if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for reasonable fees and expenses of counsel pursuant to
Section 4(a)(iii) above, such indemnifying party agrees that it  shall be liable
for any settlement effected without its written consent if (i) such settlement
is entered into more than 45 days after receipt by such indemnifying party of
the aforesaid request, (ii) such indemnifying party shall have received notice
of the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement; provided that an indemnifying party shall not be liable for any such
settlement effected without its consent if such indemnifying party, prior to the
date of such settlement, (1) reimburses such indemnified party in accordance
with such request for the amount of such fees and expenses of counsel as the
indemnifying party believes in good faith to be reasonable and (2) provides
written notice to the indemnified party that the indemnifying party disputes in
good faith the reasonableness of the unpaid balance of such fees and expenses.

          (e)  In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is judicially determined to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company, the Trust, and
the Holders shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Company, the Trust, and the Holders, as incurred; provided that
                                                                  --------     
no Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
that was not guilty of such fraudulent misrepresentation.  As between the
Company, the Trust, and the Holders, such parties shall contribute to such
aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by such indemnity agreement in such proportion as shall be
appropriate to reflect the relative fault of the Company and Trust, on the one
hand, and the Holders, on the other hand, with respect to the statements or
omissions which resulted in such loss, liability, claim, damage or expense, or
action in respect thereof, as well as any other relevant equitable
considerations. The relative fault of the Company and the Trust, on the one
hand, and of the Holders, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Trust, on the one hand, or
by or on behalf of the Holders, on the other, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company, the Trust and the Holders of the Registrable
Securities agree that it would not

                                      26
<PAGE>
 
be just and equitable if contribution pursuant to this Section 4 were to be
determined by pro rata allocation or by any other method of allocation that does
not take into account the relevant equitable considerations.  For purposes of
this Section 4, each affiliate of a Holder, and each director, officer,
employee, agent and Person, if any, who controls a Holder or such affiliate
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act shall have the same rights to contribution as such Holder, and each
director of each of the Company or the Trust, each officer of each of the
Company or the Trust who signed the Registration Statement, and each Person, if
any, who controls each of the Company and the Trust within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have
the same rights to contribution as each of the Company or the Trust.

          5.   Participation in Underwritten Registrations.  No Holder may
               -------------------------------------------                
participate in any underwritten registration hereunder unless such Holder (a)
agrees to sell such Holder's Registrable Securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements, lock-up letters and
other documents reasonably required under the terms of such underwriting
arrangements.

          6.   Selection of Underwriters.  The Holders of Registrable
               -------------------------                              
Securities covered by the Shelf Registration Statement who desire to do so may
sell the securities covered by such Shelf Registration in an underwritten
offering.  In any such underwritten offering, the underwriter or underwriters
and manager or managers that will administer the offering will be selected by
the Holders of a majority in aggregate principal amount of the Registrable
Securities included in such offering; provided, however, that such underwriters
                                      --------  -------                        
and managers must be reasonably satisfactory to the Company and the Trust.  Any
such underwriter(s) shall enter into a customary underwriting agreement with
customary indemnification of the Company and the Trust.

          7.   Miscellaneous.
               ------------- 

          (a)  Rule 144 and Rule 144A.  For so long as the Company or the Trust
               ----------------------                                          
is subject to the reporting requirements of Section 13 or 15 of the Exchange Act
and any Registrable Securities remain outstanding, the Company and the Trust, as
the case may be, will use its best efforts to file the reports required to be
filed by it under the Securities Act and Section 13(a) or 15(d) of the Exchange
Act and the rules and regulations adopted by the SEC thereunder, that if it
ceases to be so required to file such reports, it will, upon the request of any
Holder of Registrable Securities (a) make publicly available such information as
is necessary to permit sales of their securities pursuant to Rule 144 under the
Securities Act, (b) deliver such information to a prospective purchaser as is

                                      27
<PAGE>
 
necessary to permit sales of their securities pursuant to Rule 144A under the
Securities Act and it will take such further action as any Holder of Registrable
Securities may reasonably request, and (c) take such further action that is
reasonable in the circumstances, in each case, to the extent required from time
to time to enable such Holder to sell its Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by (i) Rule 144 under the Securities Act, as such rule may be amended
from time to time, (ii) Rule 144A under the Securities Act, as such rule may be
amended from time to time, or (iii) any similar rules or regulations hereafter
adopted by the SEC.  Upon the request of any Holder of Registrable Securities,
the Company and the Trusts will deliver to such Holder a written statement as to
whether it has complied with such requirements.

          (b)  No Inconsistent Agreements.  The Company or the Trust has not
               --------------------------                                   
entered into nor will the Company or the Trust on or after the date of this
Agreement enter into any agreement which is inconsistent with the rights granted
to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof.  The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Company's or the Trust's other issued and
outstanding securities under any such agreements.

          (c)  Amendments and Waivers.  The provisions of this Agreement,
               ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Trust has obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or departure; provided no amendment, modification or
                                 --------                              
supplement or waiver or consent to the departure with respect to the provisions
of Section 4 hereof shall be effective as against any Holder of Registrable
Securities unless consented to in writing by such Holder of Registrable
Securities.  Notwithstanding the foregoing sentence, (i) this Agreement may be
amended, without the consent of any Holder of Registrable Securities, by
written agreement signed by the Company, the Trust and the Initial Purchaser, to
cure any ambiguity, correct or supplement any provision of this Agreement that
may be inconsistent with any other provision of this Agreement or to make any
other provisions with respect to matters or questions arising under this
Agreement which shall not be inconsistent with other provisions of this
Agreement, (ii) this Agreement may be amended, modified or supplemented, and
waivers and consents to departures from the provisions hereof may be given, by
written agreement signed by the Company, the Trust and the Initial Purchaser to
the extent that any such amendment, modification, supplement, waiver or consent
is, in their reasonable judgment, necessary or appropriate to comply with
applicable law (including any interpretation of the Staff of the SEC) or any

                                      28
<PAGE>
 
change therein and (iii) to the extent any provision of this Agreement relates
to the Initial Purchaser, such provision may be amended, modified or
supplemented, and waivers or consents to departures from such provisions may be
given, by written agreement signed by the Initial Purchaser, the Company and the
Trust.

          (d)  Notices.  All notices and other communications provided for or
               -------                                                       
permitted hereunder shall be made in writing by hand-delivery, registered first-
class mail, telex, telecopier, or any courier guaranteeing overnight delivery

Company or the Trust by means of a notice given in accordance with the
provisions of this Section 7(d), which address initially is, with respect to the
Initial Purchaser, the address set forth in the Purchase Agreement; and (ii) if
to the Company or the Trust, initially at the Company's address set forth in the
Purchase Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 7(d).

          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next Business Day, if timely delivered to an air courier guaranteeing

          Copies of all such notices, demands, or other communications shall be
concurrently delivered by the Person giving the same to the Trustee, at the
address specified in the Indenture.

          (e)  Successors and Assigns.  This Agreement shall inure to the
               ----------------------                                    
benefit of and be binding upon the successors, assigns and transferees of the
Initial Purchaser, including, without limitation and without the need for an
express assignment, subsequent Holders; provided, however, that nothing herein
                                        --------  -------                     
shall be deemed to permit any assignment, transfer or other disposition of
Registrable Securities in violation of the terms of the Purchase Agreement or
the Indenture.  If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person
shall be conclusively deemed to have agreed to be bound by and to perform all of
the terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

          (f)  Third Party Beneficiary.  The Initial Purchaser shall be a third
               -----------------------                                         
party beneficiary of the agreements made hereunder between the Company and the
Trust, on the one hand, and the Holders, on the other hand, and shall have the
right to enforce such agreements directly to the extent it deems such
enforcement

                                      29
<PAGE>
 
necessary or advisable to protect its rights or the rights of Holders hereunder.

          (g)  Counterparts.  This Agreement may be executed in any number of
               ------------

when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (h)  Headings.  The headings in this Agreement are for convenience of
               --------                                                        
reference only and shall not limit or otherwise affect the meaning hereof.

          (i)  GOVERNING LAW.  THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE
               -------------                                                   
IN THE STATE OF NEW YORK.  THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT,
AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING

HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW
YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

          (j)  Severability.  In the event that any one or more of the
               ------------                                           
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

          (k)  Securities Held by the Company, the Trust or its Affiliates.
               -----------------------------------------------------------  
Whenever the consent or approval of Holders of a specified percentage of
Registrable Securities is required hereunder, Registrable Securities held by the
Company, the Trust or its affiliates (as such term is defined in Rule 405 under

approval was given by the Holders of such required percentage.
