SECTION 2. HOLDERS

               A Person is deemed to be a holder of Transfer Restricted
Securities (each, a "Holder") whenever such Person owns Transfer Restricted
Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

               (a) Unless the Exchange Offer shall not be permitted by
applicable federal law (after the procedures set forth in Section 6(a)(i) below
have been complied with), the Issuers shall (i) cause the Exchange Offer
Registration Statement to be filed with the Commission as soon as practicable
after the Closing Date, but in no event later than 150 days after the Closing
Date (such 150th day being the "Filing Deadline"), (ii) use their commercially
reasonable best efforts to cause such Exchange Offer Registration Statement to
become effective at the earliest possible time, but in no event later than 210
days after the Closing Date (such 210th day being the "Effectiveness Deadline"),
(iii) in connection with the foregoing, (A) file all pre-effective amendments to
such Exchange Offer Registration Statement as may be necessary in order to cause
it to become effective, (B) file, if applicable, a post-effective amendment to
such Exchange Offer Registration Statement pursuant to Rule 430A under the
Securities Act and (C) cause all necessary filings, if any, in connection with
the registration and qualification of the Exchange Securities to be made

                                       3
<PAGE>   5

under the Blue Sky laws of such jurisdictions as are necessary to permit
Consummation of the Exchange Offer, and (iv) upon the effectiveness of such
Exchange Offer Registration Statement, commence and Consummate the Exchange
Offer. The Exchange Offer shall be on the appropriate form permitting (i)
registration of the Exchange Securities to be offered in exchange for the
Securities that are Transfer Restricted Securities and (ii) resales of Exchange
Securities by Broker-Dealers that tendered into the Exchange Offer Securities
that such Broker-Dealer acquired for its own account as a result of market
making activities or other trading activities (other than Securities acquired
directly from the Trust or any of its Affiliates) as contemplated by Section
3(c) below.

               (b) The Trust and the Guarantor shall use their respective
commercially reasonable best efforts to cause the Exchange Offer Registration
Statement to be effective continuously, and shall keep the Exchange Offer open
for a period of not less than the minimum period required under applicable
federal and state securities laws to Consummate the Exchange Offer; provided,
however, that in no event shall such period be less than 20 business days. The
Trust and the Guarantor shall cause the Exchange Offer to comply with all
applicable federal and state securities laws. No securities other than the
Exchange Securities shall be included in the Exchange Offer Registration
Statement. The Trust and the Guarantor shall use their respective commercially
reasonable best efforts to cause the Exchange Offer to be Consummated on the
earliest practicable date after the Exchange Offer Registration Statement has
become effective, but in no event later than 45 business days thereafter (such
45th day being the "Consummation Deadline").

               (c) The Trust shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Broker-Dealer who holds Transfer Restricted Securities
that were acquired for the account of such Broker-Dealer as a result of
market-making activities or other trading activities (other than Securities
acquired directly from the Trust or any Affiliate of the Trust), may exchange
such Transfer Restricted Securities pursuant to the Exchange Offer. Such "Plan
of Distribution" section shall also contain all other information with respect
to such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement. See the Shearman & Sterling no-action letter (available
July 2, 1993).

               Because such Broker-Dealer may be deemed to be an "underwriter"
within the meaning of the Securities Act and must, therefore, deliver a
prospectus meeting the requirements of the Securities Act in connection with its
initial sale of any Exchange Securities received by such Broker-Dealer in the
Exchange Offer, the Trust and Guarantor shall permit the use of the Prospectus
contained in the Exchange Offer Registration Statement by such Broker-Dealer to
satisfy such prospectus delivery requirement. To the extent necessary to ensure
that the prospectus contained in the Exchange Offer Registration Statement is
available for sales of Exchange Securities by Broker-Dealers, the Trust and the
Guarantor agree to use their respective commercially reasonable best efforts to
keep the Exchange Offer Registration Statement continuously effective,
supplemented, amended and current as required by and subject to the

                                       4
<PAGE>   6

provisions of Section 6(a) and (c) hereof and in conformity with the
requirements of this Agreement, the Securities Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
one year from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto. The Trust and the Guarantor shall provide
sufficient copies of the latest version of such Prospectus to such
Broker-Dealers, promptly upon request, and in no event later than one day after
such request, at any time during such period.

SECTION 4. SHELF REGISTRATION

               (a) Shelf Registration. If (i) the Exchange Offer is not
permitted by applicable law (after the Trust and the Guarantor have complied
with the procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of
Transfer Restricted Securities shall notify the Trust within 20 business days
following the Consummation Deadline that (A) such Holder was prohibited by law
or Commission policy from participating in the Exchange Offer or (B) such Holder
may not resell the Exchange Securities acquired by it in the Exchange Offer to
the public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds
Securities acquired directly from the Trust or any of its Affiliates, then the
Trust and the Guarantor shall:

                (x)     cause to be filed, on or prior to 30 days after the
        earlier of (i) the date on which the Trust determines that the Exchange
        Offer Registration Statement cannot be filed as a result of clause
        (a)(i) above and (ii) the date on which the Trust receives the notice
        specified in clause (a)(ii) above, (such earlier date, the "Filing
        Deadline"), a shelf registration statement pursuant to Rule 415 under
        the Securities Act (which may be an amendment to the Exchange Offer
        Registration Statement (the "Shelf Registration Statement")), relating
        to all Transfer Restricted Securities, and

                (y)     shall use their respective commercially reasonable best
        efforts to cause such Shelf Registration Statement to become effective
        on or prior to 60 days after the Filing Deadline for the Shelf
        Registration Statement (such 60th day the "Effectiveness Deadline").

               If, after the Trust has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Trust is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
provided that, in such event, the Trust shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y).

               To the extent necessary to ensure that the Shelf Registration
Statement is available for sales of Transfer Restricted Securities by the
Holders thereof entitled to the benefit of this Section 4(a) and the other
securities required to be registered therein pursuant to Section 6(b)(ii)
hereof, the Trust and the Guarantor shall use their respective best efforts to
keep any Shelf

                                       5
<PAGE>   7

Registration Statement required by this Section 4(a) continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Sections 6(b) and (c) hereof and in conformity with the requirements of this
Agreement, the Securities Act and the policies, rules and regulations of the
Commission as announced from time to time, for a period of at least two years
(as extended pursuant to Section 6(c)(i)) following the Closing Date, or such
shorter period as will terminate when all Transfer Restricted Securities covered
by such Shelf Registration Statement have been sold pursuant thereto.

               (b) Provision by Holders of Certain Information in Connection
with the Shelf Registration Statement. No Holder of Transfer Restricted
Securities may include any of its Transfer Restricted Securities in any Shelf
Registration Statement pursuant to this Agreement unless and until such Holder
furnishes to the Trust in writing, within 20 days after receipt of a request
therefor, the information specified in Item 507 or 508 of Regulation S-K, as
applicable, of the Securities Act for use in connection with any Shelf
Registration Statement or Prospectus or preliminary Prospectus included therein.
No Holder of Transfer Restricted Securities shall be entitled to liquidated
damages pursuant to Section 5 hereof unless and until such Holder shall have
provided all such information. Each selling Holder agrees to promptly furnish
additional information required to be disclosed in order to make the information
previously furnished to the Issuers by such Holder not materially misleading.

SECTION 5. LIQUIDATED DAMAGES

               If (i) any Registration Statement required by this Agreement is
not filed with the Commission on or prior to the applicable Filing Deadline,
(ii) any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
or (iv) any Registration Statement required by this Agreement is filed and
declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective immediately (each such event referred to
in clauses (i) through (iv), a "Registration Default"), then the Issuers hereby
jointly and severally agree to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages in an amount equal to $.05 per
week per $1,000 in liquidation amount of Transfer Restricted Securities held by
such Holder for each week or portion thereof that the Registration Default
continues for the first 90-day period immediately following the occurrence of
such Registration Default. The amount of the liquidated damages shall increase
by an additional $.05 per week per $1,000 in liquidation amount of Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of liquidated
damages of $.25 per week per $1,000 in liquidation amount of Transfer Restricted
Securities; provided that the Issuers shall in no event be required to pay
liquidated damages for more than one Registration Default at any given time.
Notwithstanding anything to the contrary set forth herein, (1) upon filing of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (i) above, (2) upon the effectiveness of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (ii) above, (3) upon Consummation of the
Exchange Offer, in the case of (iii) above, or (4) upon the filing of a
post-effective amendment to the Registration

                                       6
<PAGE>   8

Statement or an additional Registration Statement that causes the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration Statement)
to again be declared effective or made usable in the case of (iv) above, the
liquidated damages payable with respect to the Transfer Restricted Securities as
a result of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.

               All accrued liquidated damages shall be paid to the Holders
entitled thereto, in the manner provided for the payment of distributions in the
Declaration, on each Distribution Date, as more fully set forth in the
Declaration and the Securities. Notwithstanding the fact that any Securities for
which liquidated damages are due cease to be Transfer Restricted Securities, all
obligations of the Issuers to pay liquidated damages with respect to Securities
shall survive until such time as such obligations with respect to such
Securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

               (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Trust and the Guarantor shall (x) comply with all applicable
provisions of Section 6(c) below, (y) use their respective commercially
reasonable best efforts to effect such exchange and to permit the resale of
Exchange Securities by Broker-Dealers that tendered in the Exchange Offer
Securities that such Broker-Dealer acquired for its own account as a result of
its market making activities or other trading activities (other than Securities
acquired directly from the Trust or any of its Affiliates) being sold in
accordance with the intended method or methods of distribution thereof, and (z)
comply with all of the following provisions:

               (i) If, following the date hereof there has been announced a
        change in Commission policy with respect to exchange offers such as the
        Exchange Offer that, in the reasonable opinion of counsel to the Trust
        raises a substantial question as to whether the Exchange Offer is
        permitted by applicable federal law, the Issuers hereby agree to seek a
        no-action letter or other favorable decision from the Commission
        allowing the Issuers to Consummate an Exchange Offer for such Transfer
        Restricted Securities. The Issuers hereby agree to pursue the issuance
        of such a decision to the Commission staff level. In connection with the
        foregoing, the Trust and the Guarantor hereby agree to take all such
        other actions as may be requested by the Commission or otherwise
        required in connection with the issuance of such decision, including
        without limitation (A) participating in telephonic conferences with the
        Commission, (B) delivering to the Commission staff an analysis prepared
        by counsel to the Trust setting forth the legal bases, if any, upon
        which such counsel has concluded that such an Exchange Offer should be
        permitted and (C) diligently pursuing a resolution (which need not be
        favorable) by the Commission staff.

               (ii) As a condition to its participation in the Exchange Offer,
        each Holder of Transfer Restricted Securities (including, without
        limitation, any Holder who is a Broker Dealer) shall furnish, upon the
        request of the Trust, prior to the Consummation of the Exchange Offer, a
        written representation to the Issuers (which may be contained in the
        letter of transmittal contemplated by the Exchange Offer Registration
        Statement) to the effect that (A) it is not an Affiliate of the Trust,
        (B) it is not engaged in, and does not intend to engage in, and has no
        arrangement or understanding with any person to

                                       7
<PAGE>   9

        participate in, a distribution of the Exchange Securities to be issued
        in the Exchange Offer and (C) it is acquiring the Exchange Securities in
        its ordinary course of business. As a condition to its participation in
        the Exchange Offer, each Holder using the Exchange Offer to participate
        in a distribution of the Exchange Securities shall acknowledge and agree
        that, if the resales are of Exchange Securities obtained by such Holder
        in exchange for Securities acquired directly from the Trust or an
        Affiliate thereof, it (1) could not, under Commission policy as in
        effect on the date of this Agreement, rely on the position of the
        Commission enunciated in Morgan Stanley and Co., Inc. (available June 5,
        1991) and Exxon Capital Holdings Corporation (available May 13, 1988),
        as interpreted in the Commission's letter to Shearman & Sterling dated
        July 2, 1993, and similar no-action letters (including, if applicable,
        any no-action letter obtained pursuant to clause (i) above), and (2)
        must comply with the registration and prospectus delivery requirements
        of the Securities Act in connection with a secondary resale transaction
        and that such a secondary resale transaction must be covered by an
        effective registration statement containing the selling security holder
        information required by Item 507 or 508, as applicable, of Regulation
        S-K.

               (iii) Prior to effectiveness of the Exchange Offer Registration
        Statement, the Issuers shall provide a supplemental letter to the
        Commission (A) stating that the Issuers are registering the Exchange
        Offer in reliance on the position of the Commission enunciated in Exxon
        Capital Holdings Corporation (available May 13, 1988), Morgan Stanley
        and Co., Inc. (available June 5, 1991) as interpreted in the
        Commission's letter to Shearman & Sterling dated July 2, 1993, and, if
        applicable, any no-action letter obtained pursuant to clause (i) above,
        (B) including a representation that none of the Issuers has entered into
        any arrangement or understanding with any Person to distribute the
        Exchange Securities to be received in the Exchange Offer and that, to
        the best of the Issuer's information and belief, each Holder
        participating in the Exchange Offer is acquiring the Exchange Securities
        in its ordinary course of business and has no arrangement or
        understanding with any Person to participate in the distribution of the
        Exchange Securities received in the Exchange Offer and (C) any other
        undertaking or representation required by the Commission as set forth in
        any no-action letter obtained pursuant to clause (i) above, if
        applicable.

               (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Issuers shall:

               (i) comply with all the provisions of Section 6(c) below and use
        their respective commercially reasonable best efforts to effect such
        registration to permit the sale of the Transfer Restricted Securities
        being sold in accordance with the intended method or methods of
        distribution thereof (as indicated in the information furnished to the
        Issuers pursuant to Section 4(b) hereof), and pursuant thereto the
        Issuers shall prepare and file with the Commission a Registration
        Statement relating to the registration on any appropriate form under the
        Securities Act, which form shall be available for the sale of the

               (ii) issue, upon the request of any Holder or purchaser of
        Securities covered by any Shelf Registration Statement contemplated by
        this Agreement, Exchange Securities having an aggregate liquidation
        amount equal to the aggregate liquidation amount of Securities sold
        pursuant to the Shelf Registration Statement and surrendered to the
        Trust for cancellation; the Trust shall register Exchange Securities on
        the Shelf Registration Statement for this purpose and issue the Exchange
        Securities to the purchaser(s) of securities subject to the Shelf
        Registration Statement in the names as such purchaser(s) shall
        designate.

               (iii) make available, at reasonable times, for inspection by each
        Holder eligible to include Securities in the Shelf Registration
        Statement and any attorney or accountant retained by such Holders, all
        financial and other records, pertinent corporate documents of the
        Issuers and cause the respective Issuers' officers, directors and
        employees to supply all information reasonably requested by any such
        Holder, attorney or accountant in connection with such Registration
        Statement or any post-effective amendment thereto subsequent to the
        filing thereof and prior to its effectiveness;

               (iv) if requested by any Holders eligible to include Securities
        in the Shelf Registration Statement in connection with a sale or any
        Affiliated Market Maker, promptly include in any Registration Statement
        or Prospectus, pursuant to a supplement or post-effective amendment if
        necessary, such information as such Holders may reasonably request to
        have included therein, including, without limitation, information
        relating to the "Plan of Distribution" of the Transfer Restricted
        Securities; and make all required filings of such Prospectus supplement
        or post-effective amendment as soon as practicable after the Issuers are
        notified of the matters to be included in such Prospectus supplement or
        post-effective amendment.

               (c) General Provisions. In connection with any Registration
Statement and any related Prospectus required by this Agreement, the Issuers
shall:

               (i) use their respective commercially reasonable best efforts to
        keep such Registration Statement continuously effective and provide all
        requisite financial statements for the period specified in Sections 3 or
        4 of this Agreement, as applicable. Upon the occurrence of any event
        that would cause any such Registration Statement or the Prospectus
        contained therein (A) to contain an untrue statement of material fact or
        omit to state any material fact necessary to make the statements therein
        not misleading or (B) not to be effective and usable for the exchange or
        resale of Transfer Restricted Securities during the period required by
        this Agreement, the Issuers shall file promptly an appropriate amendment
        to such Registration Statement curing such defect, and, if Commission
        review is required, use their respective best efforts to cause such
        amendment to be declared effective as soon as practicable;

               (ii) prepare and file with the Commission such amendments and
        post-effective amendments to the applicable Registration Statement as
        may be necessary to keep such Registration Statement effective for the
        applicable period set forth in Sections 3 or 4 hereof, as the case may
        be; cause the Prospectus to be supplemented by any required

                                       9
<PAGE>   11

        Prospectus supplement, and as so supplemented to be filed pursuant to
        Rule 424 under the Securities Act, and to comply fully with Rules 424,
        430A and 462, as applicable, under the Securities Act in a timely
        manner; and comply with the provisions of the Securities Act with
        respect to the disposition of all securities, instruments or exchange
        instruments, as the case may be, covered by such Registration Statement
        during the applicable period in accordance with the intended method or
        methods of distribution by the sellers thereof set forth in such
        Registration Statement or supplement to the Prospectus;

               (iii) advise each Holder promptly and, if requested by such
        Holder, confirm such advice in writing, (A) when the Prospectus or any
        Prospectus supplement or post-effective amendment has been filed, and,
        with respect to any applicable Registration Statement or any
        post-effective amendment thereto, when the same has become effective,
        (which advice shall be furnished by the issuance of a press release or
        similar public announcement and through the Depository Trust Corporation
        or any successor clearing agent), (B) of any request by the Commission
        for amendments to the Registration Statement or amendments or
        supplements to the Prospectus or for additional information relating
        thereto, (C) of the issuance by the Commission of any stop order
        suspending the effectiveness of the Registration Statement under the
        Securities Act or of the suspension by any state securities commission
        of the qualification of the Exchange Securities or the Transfer
        Restricted Securities for offering or sale in any jurisdiction, or the
        initiation of any proceeding for any of the preceding purposes, (D) of
        the existence of any fact or the happening of any event that makes any
        statement of a material fact made in the Registration Statement, the
        Prospectus, any amendment or supplement thereto or any document
        incorporated by reference therein untrue, or that requires the making of
        any additions to or changes in the Registration Statement in order to
        make the statements therein not misleading, or that requires the making
        of any additions to or changes in the Prospectus in order to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading. If at any time the Commission shall issue any
        stop order suspending the effectiveness of the Registration Statement,
        or any state securities commission or other regulatory authority shall
        issue an order suspending the qualification or exemption from
        qualification of the Exchange Securities or the Transfer Restricted
        Securities under state securities or Blue Sky laws, the Issuers shall
        use their respective best efforts to obtain the withdrawal or lifting of
        such order at the earliest possible time;

               (iv) subject to Section 6(c)(i), if any fact or event
        contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
        prepare a supplement or post-effective amendment to the Registration
        Statement or related Prospectus or any document incorporated therein by
        reference or file any other required document so that, as thereafter
        delivered to the purchasers of Exchange Securities or Transfer
        Restricted Securities, the Prospectus will not contain an untrue
        statement of a material fact or omit to state any material fact
        necessary to make the statements therein, in the light of the
        circumstances under which they were made, not misleading;

               (v) furnish to each Holder in connection with such exchange or
        sale, if any, before filing with the Commission, copies of any
        Registration Statement or any Prospectus included therein or any
        amendments or supplements to any such Registration Statement or

                                       10
<PAGE>   12

        Prospectus (including all documents incorporated by reference after the
        initial filing of such Registration Statement), which documents will be
        subject to the review and comment of such Holders in connection with
        such sale, if any, for a period of at least five Business Days, and the
        Trust will not file any such Registration Statement or Prospectus or any
        amendment or supplement to any such Registration Statement or Prospectus
        (including all such documents incorporated by reference) to which such
        Holders shall reasonably object within five Business Days after the
        receipt thereof. A Holder shall be deemed to have reasonably objected to
        such filing if such Registration Statement, amendment, Prospectus or
        supplement, as applicable, as proposed to be filed, contains an untrue
        statement of a material fact or omit to state any material fact
        necessary to make the statements therein not misleading or fails to
        comply with the applicable requirements of the Securities Act;

               (vi) promptly prior to the filing of any document that is to be
        incorporated by reference into a Registration Statement or Prospectus,
        provide copies of such document to each Holder in connection with such
        exchange or sale, if any, make the respective Issuers' representatives
        available for discussion of such document and other customary due
        diligence matters, and include such information in such document prior
        to the filing thereof as such Holders may reasonably request;

               (vii) furnish to each Holder in connection with such exchange or
        sale, without charge, at least one copy of the Registration Statement,
        as first filed with the Commission, and of each amendment thereto,
        including all documents incorporated by reference therein and all
        exhibits (including exhibits incorporated therein by reference);

               (viii) deliver to each Holder without charge, as many copies of
        the Prospectus (including each preliminary prospectus) and any amendment
        or supplement thereto as such Persons reasonably may request; the
        Issuers hereby consent to the use (in accordance with law) of the
        Prospectus and any amendment or supplement thereto by each selling
        Holder in connection with the offering and the sale of the Exchange
        Securities or the Transfer Restricted Securities covered by the
        Prospectus or any amendment or supplement thereto;

               (ix) upon the request of any Holder, enter into such agreements
        (including underwriting agreements) and make such representations and
        warranties and take all such other actions in connection therewith in
        order to expedite or facilitate the disposition of the Transfer
        Restricted Securities pursuant to any applicable Registration Statement
        contemplated by this Agreement as may be reasonably requested by any
        Holder in connection with any sale or resale pursuant to any applicable
        Registration Statement. In such connection, the Issuers shall:

                        (A) upon request of any Holder, furnish (or in the case
                of paragraphs (2) and (3), use their commercially reasonable
                best efforts to cause to be furnished) to each Holder, upon
                Consummation of the Exchange Offer or upon the effectiveness of
                the Shelf Registration Statement, as the case may be:

                                (1) a certificate, dated such date, signed on
                        behalf of the Issuers by (x) the President or any Vice
                        President, or in the case of the Guarantor and

                                       11

                        DGmbH (as defined in the Purchase Agreement) members of
                        the board (Vorstand or Geschaftsfuhrung), as the case
                        may be, and (y) a principal financial or accounting
                        officer of such Issuer, confirming, as of the date
                        thereof, the matters set forth in Sections 6(y)(iv),
                        9(a) and 9(b) of the Purchase Agreement and such other
                        similar matters as such Holders may reasonably request;

                                (2) an opinion, dated the date of Consummation
                        of the Exchange Offer or the date of effectiveness of
                        the Shelf Registration Statement, as the case may be, of
                        counsel for the Issuers covering matters similar to
                        those set forth in paragraph (f) of Section 9 of the
                        Purchase Agreement and as to the effectiveness of the
                        Registration Statement, the absence of stop orders with
                        respect thereto and compliance of the Registration
                        Statement as to form with the requirements of the
                        Securities Act and the TIA and in any event including a
                        statement substantially to the effect that such counsel
                        has participated in conferences with officers and other
                        representatives of the Issuers, representatives of the
                        independent public accountants for the Guarantor
                        regarding the Registration Statement and the Prospectus
                        contained therein and have considered the matters
                        required to be stated therein and the statements
                        contained therein, although such counsel has not
                        independently verified the accuracy, completeness or
                        fairness of such statements; and that such counsel
                        advises that, on the basis of the foregoing (relying as
                        to materiality to the extent such counsel deems
                        appropriate upon the statements of officers and other
                        representatives of the Trust and the Guarantor) and
                        without independent check or verification), no facts
                        came to such counsel's attention that caused such
                        counsel to believe that the applicable Registration
                        Statement, at the time such Registration Statement or
                        any post-effective amendment thereto became effective
                        and, in the case of the Exchange Offer Registration
                        Statement, as of the date of Consummation of the
                        Exchange Offer, contained an untrue statement of a
                        material fact or omitted to state a material fact
                        required to be stated therein or necessary to make the
                        statements therein not misleading, or that the
                        Prospectus contained in such Registration Statement as
                        of its date and, in the case of the opinion dated the
                        date of Consummation of the Exchange Offer, as of the
                        date of Consummation, contained an untrue statement of a
                        material fact or omitted to state a material fact
                        necessary in order to make the statements therein, in
                        the light of the circumstances under which they were
                        made, not misleading. Without limiting the foregoing,
                        such counsel may state further that such counsel assumes
                        no responsibility for, and has not independently
                        verified, the accuracy, completeness or fairness of the
                        financial statements, notes and schedules and other
                        financial data included in any Registration Statement
                        contemplated by this Agreement or the related
                        Prospectus; and

                                (3) a customary comfort letter, dated the date
                        of Consummation of the Exchange Offer, or as of the date
                        of effectiveness of the Shelf

                        Registration Statement, as the case may be, from the
                        Guarantor's independent accountants, in the customary
                        form and covering matters of the type customarily
                        covered in comfort letters to underwriters in connection
                        with underwritten offerings, and affirming the matters
                        set forth in the comfort letters delivered pursuant to
                        Section 9(e) of the Purchase Agreement.

                        (B) deliver such other documents and certificates as may
                be reasonably requested by the selling Holders to such Persons
                to evidence compliance with the matters covered in clause (A)
                above and with any customary conditions contained in the any
                agreement entered into by the Issuers pursuant to this clause
                (ix);

                (x) prior to any public offering of Exchange Securities or
        Transfer Restricted Securities, cooperate with the selling Holders and
        their counsel in connection with the registration and qualification of
        the Exchange Securities or Transfer Restricted Securities under the
        state securities or Blue Sky laws of such jurisdictions within the
        United States as the selling Holders may request and do any and all
        other acts or things necessary or advisable to enable the disposition in
        such jurisdictions of the Exchange Securities or Transfer Restricted
        Securities covered by the applicable Registration Statement; provided,
        however, that none of the Issuers shall be required to register or
        qualify as a foreign corporation where it is not now so qualified or to
        take any action that would subject it to the service of process in suits
        or to taxation, other than as to matters and transactions relating to
        the Registration Statement, in any jurisdiction where it is not now so
        subject;

                (xi) in connection with any sale of Transfer Restricted
        Securities that will result in such securities no longer being Transfer
        Restricted Securities, cooperate with the Holders to facilitate the
        timely preparation and delivery of global certificates representing
        Transfer Restricted Securities to be sold and not bearing any
        restrictive legends; and to register such Transfer Restricted Securities
        in such denominations and such names as the selling Holders may request
        at least two Business Days prior to such sale of Transfer Restricted
        Securities;

                (xii) use their respective commercially reasonable best efforts
        to cause the disposition of the Transfer Restricted Securities covered
        by the Registration Statement to be registered with or approved by such
        other governmental agencies or authorities as may be necessary to enable
        the seller or sellers thereof to consummate the disposition of such
        Transfer Restricted Securities, subject to the proviso contained in
        clause (x) above;

                (xiii) provide a CUSIP number for all Exchange Securities or
        Transfer Restricted Securities, as the case may be, not later than the
        effective date of a Registration Statement covering such Transfer
        Restricted Securities and provide the Trustee under the Declaration with
        printed certificates for the Transfer Restricted Securities which are in
        a form eligible for deposit with the Depository Trust Company;

                (xiv) otherwise use their respective commercially reasonable
        best efforts to comply with all applicable rules and regulations of the
        Commission, and make generally

                                       13

        available to its security holders with regard to any applicable
        Registration Statement, as soon as practicable, a consolidated earnings
        statement meeting the requirements of Rule 158 to the Securities Act
        (which need not be audited) covering a twelve-month period beginning
        after the effective date of the Registration Statement (as such term is
        defined in paragraph (c) of Rule 158 under the Securities Act);

               (xv) cause the Declaration and the Indenture to be qualified
        under the TIA not later than the effective date of the first
        Registration Statement required by this Agreement and, in connection
        therewith, cooperate with the Trustee and the Holders to effect such
        changes to the Declaration and the Indenture as may be required for such
        Declaration or Indenture to be so qualified in accordance with the terms
        of the TIA; and execute and use their best efforts to cause the Trustee
        to execute, all documents that may be required to effect such changes
        and other forms and documents required to be filed with the Commission
        to enable such Declaration or Indenture to be so qualified in a timely
        manner;

               (xvi) provide promptly to each Holder, upon request, each
        document filed with the Commission pursuant to the requirements of
        Section 13 or Section 15(d) of the Exchange Act; and

               (xvii) to use their commercially reasonable best efforts to
        cause the Exchange Securities to be listed on the Luxembourg Stock
        Exchange.

               (d) Restrictions on Holders. Each Holder agrees by acquisition of
a Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(iii)(C) or any notice from the Trust of the existence of any fact
of the kind described in Section 6(c)(iii)(D) hereof (in each case, a
"Suspension Notice"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration Statement
until (i) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is
advised in writing by the Trust that the use of the Prospectus may be resumed,
and has received copies of any additional or supplemental filings that are
incorporated by reference in the Prospectus (in each case, the "Recommencement
Date"). Each Holder receiving a Suspension Notice hereby agrees that it will
either (i) destroy any Prospectuses, other than permanent file copies, then in
such Holder's possession which have been replaced by the Trust with more
recently dated Prospectuses or (ii) deliver to the Trust (at the Trust's
expense) all copies, other than permanent file copies, then in such Holder's
possession of the Prospectus covering such Transfer Restricted Securities that
was current at the time of receipt of the Suspension Notice. The time period
regarding the effectiveness of such Registration Statement set forth in Sections
3 or 4 hereof, as applicable, shall be extended by a number of days equal to the
number of days in the period from and including the date of delivery of the
Suspension Notice to the date of delivery of the Recommencement Date.

printing of Prospectuses, messenger and delivery services and telephone; (iv)
all fees and disbursements of counsel for the Issuers; (v) all application and

               The Trust will, in any event, bear its and the Guarantor's
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expenses
of any annual audit and the fees and expenses of any Person, including special
experts, retained by the Trust or the Guarantor.

               (b) In connection with any Registration Statement required by

Statement and the Shelf Registration Statement), the Guarantor will reimburse
the Initial Purchasers and the Holders of Transfer Restricted Securities who are
tendering Securities into the Exchange Offer and/or selling or reselling
Securities or Exchange Securities pursuant to the "Plan of Distribution"
contained in the Exchange Offer Registration Statement or the Shelf Registration
Statement, as applicable, for the reasonable fees and disbursements of not more
than one counsel, who shall be Shearman & Sterling, 9 Appold Street, London EC2A
2AP, unless another firm shall be chosen by the Holders of a majority in
liquidation amount of the Transfer Restricted Securities for whose benefit such
Registration Statement is being prepared.

SECTION 8. INDEMNIFICATION

               (a) The Issuers agree, jointly and severally, to indemnify and
hold harmless each Holder, its directors, officers and each Person, if any, who
controls such Holder (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act), from and against any and all losses, claims,
damages, liabilities, judgments, (including without limitation, any legal or
other expenses incurred in connection with investigating or defending any
matter, including any action that could give rise to any such losses, claims,
damages, liabilities or judgments) caused by any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement,
preliminary prospectus or Prospectus (or any amendment or supplement thereto)
provided by the Trust to any Holder or any prospective purchaser of Exchange
Securities or registered Securities, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by an untrue
statement or omission or alleged untrue statement or omission that is based upon
information relating to any of the Holders furnished in writing so the Trust by
any of the Holders.

               (b) Each Holder of Transfer Restricted agrees, severally and not
jointly, to indemnify and hold harmless the Issuers, and their respective
directors and officers, and each person, if any, who controls (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
any Issuer, to the same extent as the foregoing indemnity from the Issuers

                                       15
<PAGE>   17

set forth in section (a) above, but only with reference to information relating
to such Holder furnished in writing to the Trust by such Holder expressly for
use in any Registration Statement. In no event shall any Holder, its directors,
officers or any Person who controls such Holder be liable or responsible for any
amount in excess of the amount by which the total amount received by such Holder
with respect to its sale of Transfer Restricted Securities pursuant to a
Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages that such
Holder, its directors, officers or any Person who controls such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

               (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and,
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all indemnified parties and all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by a majority of the
Holders, in the case of the parties indemnified pursuant to Section 8(a), and by
the Guarantor, in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against any and all losses, claims, damages, liabilities and judgments by
reason of any settlement of any action (i) effected with the indemnifying
party's written consent or (ii) effected without the indemnifying party's
written consent if the settlement is entered into more than twenty business days
after the indemnifying party shall have received a request from the indemnified
party for reimbursement for the fees and expenses of counsel (in any case where
such fees and expenses are at the expense of the indemnifying party) and, prior
to the date of such settlement, the indemnifying party shall have failed to
comply with such reimbursement request. No indemnifying party shall, without the
prior

                                       16
<PAGE>   18

written consent of the indemnified party, effect any settlement or compromise
of, or consent to the entry of judgment with respect to, any pending or
threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action 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 the indemnified party.

               (d) To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments (i) in such proportion
as is appropriate to reflect the relative benefits received by the Issuers, on
the one hand, and the Holders, on the other hand, from their sale of Transfer
Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause 8(d)(i) above but also the
relative fault of the Issuers, on the one hand, and of the Holder, on the other
hand, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative fault of the Issuers, on the one hand,
and of the Holder, 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 Issuers, on the one hand, or by the Holder, on the
other hand, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

               The Issuers and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any matter, including any
action that could have given rise to such losses, claims, damages, liabilities
or judgments. Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any Person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds (i) the
amount paid by such Holder for such Transfer Restricted Securities and (ii) the
amount of any damages which such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. 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 who was not guilty of such fraudulent misrepresentation. The Holders'
obligations to contribute pursuant to this Section 8(d) are several in
proportion to the

                                       17
<PAGE>   19

respective liquidation amount of Transfer Restricted Securities held by each
Holder hereunder and not joint.

SECTION 9. RULE 144A AND RULE 144

               The Issuers agree with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Guarantor (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Securities Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

SECTION 10. MISCELLANEOUS

               (a) Remedies. The Issuers acknowledge and agree that any failure
by the Issuers to comply with their respective obligations under Sections 3 and
4 hereof may result in material irreparable injury to the Initial Purchasers or
the Holders for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Initial Purchasers or any Holder may obtain such relief
as may be required to specifically enforce the Issuers' obligations under
Sections 3 and 4 hereof. The Issuers further agree to waive the defense in any
action for specific performance that a remedy at law would be adequate.

               (b) No Inconsistent Agreements. None of the Issuers will, on or
after the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. Nothing in this
Agreement shall preclude or limit the Issuers from (i) conducting the Exchange
Offer pursuant to a single registration statement relating to both (A) the
Exchange Offer and (B) a substantially identical exchange offer relating to up
to Euro 300 million of euro-denominated trust preferred securities (and related
trust guarantees, senior subordinated notes and note guaranties) having
substantially identical terms to the Securities (other than this currency, their
price in the initial offering, their coupon and the identity of the
issuer-trust) ("Euro Exchange Offer") or (ii) preparing and filing a single
shelf registration statement with respect to both the Preferred Securities and
the additional trust preferred securities described in the preceding clause
(i)(B), and no actions taken pursuant to or as contemplated by this sentence
will be deemed inconsistent with the rights granted to the Holders in this
Agreement, it being understood that in the event that it is impracticable to
conduct the Exchange Offer and the Euro Exchange Offer pursuant to a single
registration statement, each of the Exchange Offer and Euro Exchange Offer will
proceed separately. Except for the agreement dated as of March 2, 2000 between
the Guarantor and Persons who acquired non-voting Preference shares of the
Guarantor in the "Franconia" transaction, none of the Issuers is a party to any
agreement granting any registration rights with respect to its securities to any
person. The rights granted to the Holders hereunder do not in any

                                       18
<PAGE>   20

way conflict with and are not inconsistent with the rights granted to the
holders of the Issuer's securities of the Issuers under any agreement in effect
on the date hereof.

               (c) Amendments and Waivers. The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case of
Section 5 hereof and this Section 10(c)(i), the Trust has obtained the written
consent of Holders of all outstanding Transfer Restricted Securities and (ii) in
the case of all other provisions hereof, the Trust has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Trust or its Affiliates). Notwithstanding the foregoing, a waiver or consent to
departure from the provisions hereof that relates exclusively to the rights of
Holders whose Transfer Restricted Securities are being tendered pursuant to the
Exchange Offer, and that does not affect directly or indirectly the rights of
other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

               (d) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Issuers, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce such agreements directly to the extent they may deem such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

               (e) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail

benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express

permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms hereof or of the Purchase Agreement, the
Declaration or applicable law. If any transferee of any Holder shall acquire
Transfer Restricted Securities in any manner, whether by operation of law or
otherwise, such Transfer Restricted Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding such Transfer Restricted
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, including
the restrictions on resale set forth in this Agreement and, if applicable, the
Purchase Agreement, and such Person shall be entitled to receive the benefits
hereof.

               (g) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO THE CONFLICT OF LAW RULES THEREOF.

               (j) Severability. In the event that any one or more of the

SECTION 2. HOLDERS

               A Person is deemed to be a holder of Transfer Restricted
Securities (each, a "Holder") whenever such Person owns Transfer Restricted
Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

               (a) Unless the Exchange Offer shall not be permitted by
applicable federal law (after the procedures set forth in Section 6(a)(i) below
have been complied with), the Issuers shall (i) cause the Exchange Offer
Registration Statement to be filed with the Commission as soon as practicable
after the Closing Date, but in no event later than 150 days after the Closing
Date (such 150th day being the "Filing Deadline"), (ii) use their commercially
reasonable best efforts to cause such Exchange Offer Registration Statement to
become effective at the earliest possible time, but in no event later than 210
days after the Closing Date (such 210th day being the "Effectiveness Deadline"),
(iii) in connection with the foregoing, (A) file all pre-effective amendments to
such Exchange Offer Registration Statement as may be necessary in order to cause
it to become effective, (B) file, if applicable, a post-effective amendment to
such Exchange Offer Registration Statement pursuant to Rule 430A under the
Securities Act and (C) cause all necessary filings, if any, in connection with
the registration and qualification of the Exchange Securities to be made

                                       3
<PAGE>   5

under the Blue Sky laws of such jurisdictions as are necessary to permit
Consummation of the Exchange Offer, and (iv) upon the effectiveness of such
Exchange Offer Registration Statement, commence and Consummate the Exchange
Offer. The Exchange Offer shall be on the appropriate form permitting (i)
registration of the Exchange Securities to be offered in exchange for the
Securities that are Transfer Restricted Securities and (ii) resales of Exchange
Securities by Broker-Dealers that tendered into the Exchange Offer Securities
that such Broker-Dealer acquired for its own account as a result of market
making activities or other trading activities (other than Securities acquired
directly from the Trust or any of its Affiliates) as contemplated by Section
3(c) below.

               (b) The Trust and the Guarantor shall use their respective
commercially reasonable best efforts to cause the Exchange Offer Registration
Statement to be effective continuously, and shall keep the Exchange Offer open
for a period of not less than the minimum period required under applicable
federal and state securities laws to Consummate the Exchange Offer; provided,
however, that in no event shall such period be less than 20 business days. The
Trust and the Guarantor shall cause the Exchange Offer to comply with all
applicable federal and state securities laws. No securities other than the
Exchange Securities shall be included in the Exchange Offer Registration
Statement. The Trust and the Guarantor shall use their respective commercially
reasonable best efforts to cause the Exchange Offer to be Consummated on the
earliest practicable date after the Exchange Offer Registration Statement has
become effective, but in no event later than 45 business days thereafter (such
45th day being the "Consummation Deadline").

               (c) The Trust shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Broker-Dealer who holds Transfer Restricted Securities
that were acquired for the account of such Broker-Dealer as a result of
market-making activities or other trading activities (other than Securities
acquired directly from the Trust or any Affiliate of the Trust), may exchange
such Transfer Restricted Securities pursuant to the Exchange Offer. Such "Plan
of Distribution" section shall also contain all other information with respect
to such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement. See the Shearman & Sterling no-action letter (available
July 2, 1993).

               Because such Broker-Dealer may be deemed to be an "underwriter"
within the meaning of the Securities Act and must, therefore, deliver a
prospectus meeting the requirements of the Securities Act in connection with its
initial sale of any Exchange Securities received by such Broker-Dealer in the
Exchange Offer, the Trust and Guarantor shall permit the use of the Prospectus
contained in the Exchange Offer Registration Statement by such Broker-Dealer to
satisfy such prospectus delivery requirement. To the extent necessary to ensure
that the prospectus contained in the Exchange Offer Registration Statement is
available for sales of Exchange Securities by Broker-Dealers, the Trust and the
Guarantor agree to use their respective commercially reasonable best efforts to
keep the Exchange Offer Registration Statement continuously effective,
supplemented, amended and current as required by and subject to the

                                       4
<PAGE>   6

provisions of Section 6(a) and (c) hereof and in conformity with the
requirements of this Agreement, the Securities Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
one year from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto. The Trust and the Guarantor shall provide
sufficient copies of the latest version of such Prospectus to such
Broker-Dealers, promptly upon request, and in no event later than one day after
such request, at any time during such period.

SECTION 4. SHELF REGISTRATION

               (a) Shelf Registration. If (i) the Exchange Offer is not
permitted by applicable law (after the Trust and the Guarantor have complied
with the procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of
Transfer Restricted Securities shall notify the Trust within 20 business days
following the Consummation Deadline that (A) such Holder was prohibited by law
or Commission policy from participating in the Exchange Offer or (B) such Holder
may not resell the Exchange Securities acquired by it in the Exchange Offer to
the public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds
Securities acquired directly from the Trust or any of its Affiliates, then the
Trust and the Guarantor shall:

               (x)     cause to be filed, on or prior to 30 days after the
        earlier of (i) the date on which the Trust determines that the
        Exchange Offer Registration Statement cannot be filed as a result of
        clause (a)(i) above and (ii) the date on which the Trust receives the
        notice specified in clause (a)(ii) above, (such earlier date, the
        "Filing Deadline"), a shelf registration statement pursuant to Rule 415
        under the Securities Act (which may be an amendment to the Exchange
        Offer Registration Statement (the "Shelf Registration Statement")),
        relating to all Transfer Restricted Securities, and

                (y)     shall use their respective commercially reasonable best
        efforts to cause such Shelf Registration Statement to become effective
        on or prior to 60 days after the Filing Deadline for the Shelf
        Registration Statement (such 60th day the "Effectiveness Deadline").

               If, after the Trust has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Trust is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
provided that, in such event, the Trust shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y).

               To the extent necessary to ensure that the Shelf Registration
Statement is available for sales of Transfer Restricted Securities by the
Holders thereof entitled to the benefit of this Section 4(a) and the other
securities required to be registered therein pursuant to Section 6(b)(ii)
hereof, the Trust and the Guarantor shall use their respective best efforts to
keep any Shelf

                                       5
<PAGE>   7

Registration Statement required by this Section 4(a) continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Sections 6(b) and (c) hereof and in conformity with the requirements of this
Agreement, the Securities Act and the policies, rules and regulations of the
Commission as announced from time to time, for a period of at least two years
(as extended pursuant to Section 6(c)(i)) following the Closing Date, or such
shorter period as will terminate when all Transfer Restricted Securities covered
by such Shelf Registration Statement have been sold pursuant thereto.

               (b) Provision by Holders of Certain Information in Connection
with the Shelf Registration Statement. No Holder of Transfer Restricted
Securities may include any of its Transfer Restricted Securities in any Shelf
Registration Statement pursuant to this Agreement unless and until such Holder
furnishes to the Trust in writing, within 20 days after receipt of a request
therefor, the information specified in Item 507 or 508 of Regulation S-K, as
applicable, of the Securities Act for use in connection with any Shelf
Registration Statement or Prospectus or preliminary Prospectus included therein.
No Holder of Transfer Restricted Securities shall be entitled to liquidated
damages pursuant to Section 5 hereof unless and until such Holder shall have
provided all such information. Each selling Holder agrees to promptly furnish
additional information required to be disclosed in order to make the information
previously furnished to the Issuers by such Holder not materially misleading.

SECTION 5. LIQUIDATED DAMAGES

               If (i) any Registration Statement required by this Agreement is
not filed with the Commission on or prior to the applicable Filing Deadline,
(ii) any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
or (iv) any Registration Statement required by this Agreement is filed and
declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective immediately (each such event referred to
in clauses (i) through (iv), a "Registration Default"), then the Issuers hereby
jointly and severally agree to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages in an amount equal to Euro .05
per week per Euro 1,000 in liquidation amount of Transfer Restricted Securities
held by such Holder for each week or portion thereof that the Registration
Default continues for the first 90-day period immediately following the
occurrence of such Registration Default. The amount of the liquidated damages
shall increase by an additional Euro .05 per week per Euro 1,000 in liquidation
amount of Transfer Restricted Securities with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum amount
of liquidated damages of Euro .25 per week per Euro 1,000 in liquidation amount
of Transfer Restricted Securities; provided that the Issuers shall in no event
be required to pay liquidated damages for more than one Registration Default at
any given time. Notwithstanding anything to the contrary set forth herein, (1)
upon filing of the Exchange Offer Registration Statement (and/or, if applicable,
the Shelf Registration Statement), in the case of (i) above, (2) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon
the filing of a post-effective amendment to the Registration

                                       6
<PAGE>   8

Statement or an additional Registration Statement that causes the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration Statement)
to again be declared effective or made usable in the case of (iv) above, the
liquidated damages payable with respect to the Transfer Restricted Securities as
a result of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.

               All accrued liquidated damages shall be paid to the Holders
entitled thereto, in the manner provided for the payment of distributions in the
Declaration, on each Distribution Date, as more fully set forth in the
Declaration and the Securities. Notwithstanding the fact that any Securities for
which liquidated damages are due cease to be Transfer Restricted Securities, all
obligations of the Issuers to pay liquidated damages with respect to Securities
shall survive until such time as such obligations with respect to such
Securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

               (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Trust and the Guarantor shall (x) comply with all applicable
provisions of Section 6(c) below, (y) use their respective commercially
reasonable best efforts to effect such exchange and to permit the resale of
Exchange Securities by Broker-Dealers that tendered in the Exchange Offer
Securities that such Broker-Dealer acquired for its own account as a result of
its market making activities or other trading activities (other than Securities
acquired directly from the Trust or any of its Affiliates) being sold in
accordance with the intended method or methods of distribution thereof, and (z)
comply with all of the following provisions:

               (i) If, following the date hereof there has been announced a
        change in Commission policy with respect to exchange offers such as the
        Exchange Offer that, in the reasonable opinion of counsel to the Trust
        raises a substantial question as to whether the Exchange Offer is
        permitted by applicable federal law, the Issuers hereby agree to seek a
        no-action letter or other favorable decision from the Commission
        allowing the Issuers to Consummate an Exchange Offer for such Transfer
        Restricted Securities. The Issuers hereby agree to pursue the issuance
        of such a decision to the Commission staff level. In connection with the
        foregoing, the Trust and the Guarantor hereby agree to take all such
        other actions as may be requested by the Commission or otherwise
        required in connection with the issuance of such decision, including
        without limitation (A) participating in telephonic conferences with the
        Commission, (B) delivering to the Commission staff an analysis prepared
        by counsel to the Trust setting forth the legal bases, if any, upon
        which such counsel has concluded that such an Exchange Offer should be
        permitted and (C) diligently pursuing a resolution (which need not be
        favorable) by the Commission staff.

               (ii) As a condition to its participation in the Exchange Offer,
        each Holder of Transfer Restricted Securities (including, without
        limitation, any Holder who is a Broker Dealer) shall furnish, upon the
        request of the Trust, prior to the Consummation of the Exchange Offer, a
        written representation to the Issuers (which may be contained in the
        letter of transmittal contemplated by the Exchange Offer Registration
        Statement) to the effect that (A) it is not an Affiliate of the Trust,
        (B) it is not engaged in, and does not intend to engage in, and has no
        arrangement or understanding with any person to

                                       7
<PAGE>   9

        participate in, a distribution of the Exchange Securities to be issued
        in the Exchange Offer and (C) it is acquiring the Exchange Securities in
        its ordinary course of business. As a condition to its participation in
        the Exchange Offer, each Holder using the Exchange Offer to participate
        in a distribution of the Exchange Securities shall acknowledge and agree
        that, if the resales are of Exchange Securities obtained by such Holder
        in exchange for Securities acquired directly from the Trust or an
        Affiliate thereof, it (1) could not, under Commission policy as in
        effect on the date of this Agreement, rely on the position of the
        Commission enunciated in Morgan Stanley and Co., Inc. (available June 5,
        1991) and Exxon Capital Holdings Corporation (available May 13, 1988),
        as interpreted in the Commission'sletter to Shearman & Sterling dated
        July 2, 1993, and similar no-action letters (including, if applicable,
        any no-action letter obtained pursuant to clause (i) above), and (2)
        must comply with the registration and prospectus delivery requirements
        of the Securities Act in connection with a secondary resale transaction
        and that such a secondary resale transaction must be covered by an
        effective registration statement containing the selling security holder
        information required by Item 507 or 508, as applicable, of Regulation
        S-K.

               (iii) Prior to effectiveness of the Exchange Offer Registration
        Statement, the Issuers shall provide a supplemental letter to the
        Commission (A) stating that the Issuers are registering the Exchange
        Offer in reliance on the position of the Commission enunciated in Exxon
        Capital Holdings Corporation (available May 13, 1988), Morgan Stanley
        and Co., Inc. (available June 5, 1991) as interpreted in the
        Commission's letter to Shearman & Sterling dated July 2, 1993, and, if
        applicable, any no-action letter obtained pursuant to clause (i) above,
        (B) including a representation that none of the Issuers has entered into
        any arrangement or understanding with any Person to distribute the
        Exchange Securities to be received in the Exchange Offer and that, to
        the best of the Issuer's information and belief, each Holder
        participating in the Exchange Offer is acquiring the Exchange Securities
        in its ordinary course of business and has no arrangement or
        understanding with any Person to participate in the distribution of the
        Exchange Securities received in the Exchange Offer and (C) any other
        undertaking or representation required by the Commission as set forth in
        any no-action letter obtained pursuant to clause (i) above, if
        applicable.

        being sold in accordance with the intended method or methods of
        distribution thereof (as indicated in the information furnished to the

        Issuers shall prepare and file with the Commission a Registration
        Statement relating to the registration on any appropriate form under the
        Securities Act, which form shall be available for the sale of the
        Transfer Restricted Securities in accordance with the intended method or
        methods of distribution thereof within the time periods and otherwise in
        accordance with the provisions hereof.

               (ii) issue, upon the request of any Holder or purchaser of
        Securities covered by any Shelf Registration Statement contemplated by
        this Agreement, Exchange Securities having an aggregate liquidation
        amount equal to the aggregate liquidation amount of Securities sold
        pursuant to the Shelf Registration Statement and surrendered to the
        Trust for cancellation; the Trust shall register Exchange Securities on
        the Shelf Registration Statement for this purpose and issue the Exchange
        Securities to the purchaser(s) of securities subject to the Shelf
        Registration Statement in the names as such purchaser(s) shall
        designate.

               (iii) make available, at reasonable times, for inspection by
        each Holder eligible to include Securities in the Shelf Registration
        Statement and any attorney or accountant retained by such Holders, all
        financial and other records, pertinent corporate documents of the
        Issuers and cause the respective Issuers' officers, directors and
        employees to supply all information reasonably requested by any such
        Holder, attorney or accountant in connection with such Registration
        Statement or any post-effective amendment thereto subsequent to the
        filing thereof and prior to its effectiveness;

               (iv) if requested by any Holders eligible to include Securities
        in the Shelf Registration Statement in connection with a sale or any
        Affiliated Market Maker, promptly include in any Registration Statement
        or Prospectus, pursuant to a supplement or post-effective amendment if
        necessary, such information as such Holders may reasonably request to
        have included therein, including, without limitation, information
        relating to the "Plan of Distribution" of the Transfer Restricted
        Securities; and make all required filings of such Prospectus supplement
        or post-effective amendment as soon as practicable after the Issuers are
        notified of the matters to be included in such Prospectus supplement or
        post-effective amendment.

               (c) General Provisions. In connection with any Registration
Statement and any related Prospectus required by this Agreement, the Issuers
shall:

               (i) use their respective commercially reasonable best efforts to
        keep such Registration Statement continuously effective and provide all
        requisite financial statements for the period specified in Sections 3 or
        4 of this Agreement, as applicable. Upon the occurrence of any event
        that would cause any such Registration Statement or the Prospectus
        contained therein (A) to contain an untrue statement of material fact or
        omit to state any material fact necessary to make the statements therein
        not misleading or (B) not to be effective and usable for the exchange or
        resale of Transfer Restricted Securities during the period required by
        this Agreement, the Issuers shall file promptly an appropriate amendment
        to such Registration Statement curing such defect, and, if Commission
        review is required, use their respective best efforts to cause such
        amendment to be declared effective as soon as practicable;

               (ii) prepare and file with the Commission such amendments and
        post-effective amendments to the applicable Registration Statement as
        may be necessary to keep such Registration Statement effective for the
        applicable period set forth in Sections 3 or 4 hereof, as the case may
        be; cause the Prospectus to be supplemented by any required

                                       9
<PAGE>   11

        Prospectus supplement, and as so supplemented to be filed pursuant to
        Rule 424 under the Securities Act, and to comply fully with Rules 424,
        430A and 462, as applicable, under the Securities Act in a timely
        manner; and comply with the provisions of the Securities Act with
        respect to the disposition of all securities, instruments or exchange
        instruments, as the case may be, covered by such Registration Statement
        during the applicable period in accordance with the intended method or
        methods of distribution by the sellers thereof set forth in such
        Registration Statement or supplement to the Prospectus;

               (iii) advise each Holder promptly and, if requested by such
        Holder, confirm such advice in writing, (A) when the Prospectus or any
        Prospectus supplement or post-effective amendment has been filed, and,
        with respect to any applicable Registration Statement or any
        post-effective amendment thereto, when the same has become effective,
        (which advice shall be furnished by the issuance of a press release or
        similar public announcement and through the Depository Trust Corporation
        or any successor clearing agent), (B) of any request by the Commission
        for amendments to the Registration Statement or amendments or
        supplements to the Prospectus or for additional information relating
        thereto, (C) of the issuance by the Commission of any stop order
        suspending the effectiveness of the Registration Statement under the
        Securities Act or of the suspension by any state securities commission
        of the qualification of the Exchange Securities or the Transfer
        Restricted Securities for offering or sale in any jurisdiction, or the
        initiation of any proceeding for any of the preceding purposes, (D) of
        the existence of any fact or the happening of any event that makes any
        statement of a material fact made in the Registration Statement, the
        Prospectus, any amendment or supplement thereto or any document
        incorporated by reference therein untrue, or that requires the making of
        any additions to or changes in the Registration Statement in order to
        make the statements therein not misleading, or that requires the making
        of any additions to or changes in the Prospectus in order to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading. If at any time the Commission shall issue any
        stop order suspending the effectiveness of the Registration Statement,
        or any state securities commission or other regulatory authority shall
        issue an order suspending the qualification or exemption from
        qualification of the Exchange Securities or the Transfer Restricted
        Securities under state securities or Blue Sky laws, the Issuers shall
        use their respective best efforts to obtain the withdrawal or lifting of
        such order at the earliest possible time;

               (iv) subject to Section 6(c)(i), if any fact or event
        contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
        prepare a supplement or post-effective amendment to the Registration
        Statement or related Prospectus or any document incorporated therein by
        reference or file any other required document so that, as thereafter
        delivered to the purchasers of Exchange Securities or Transfer
        Restricted Securities, the Prospectus will not contain an untrue
        statement of a material fact or omit to state any material fact
        necessary to make the statements therein, in the light of the
        circumstances under which they were made, not misleading;

               (v) furnish to each Holder in connection with such exchange or
        sale, if any, before filing with the Commission, copies of any
        Registration Statement or any Prospectus included therein or any
        amendments or supplements to any such Registration Statement or
        Prospectus (including all documents incorporated by reference after the
        initial filing of such Registration Statement), which documents will be
        subject to the review and comment of such Holders in connection with
        such sale, if any, for a period of at least five Business Days, and the
        Trust will not file any such Registration Statement or

                                       10

<PAGE>   12

        Prospectus or any amendment or supplement to any such Registration
        Statement or Prospectus (including all such documents incorporated by
        reference) to which such Holders shall reasonably object within five
        Business Days after the receipt thereof. A Holder shall be deemed to
        have reasonably objected to such filing if such Registration Statement,
        amendment, Prospectus or supplement, as applicable, as proposed to be
        filed, contains an untrue statement of a material fact or omit to state
        any material fact necessary to make the statements therein not
        misleading or fails to comply with the applicable requirements of the
        Securities Act;

               (vi) promptly prior to the filing of any document that is to be
        incorporated by reference into a Registration Statement or Prospectus,
        provide copies of such document to each Holder in connection with such
        exchange or sale, if any, make the respective Issuers' representatives
        available for discussion of such document and other customary due
        diligence matters, and include such information in such document prior
        to the filing thereof as such Holders may reasonably request;

               (vii) furnish to each Holder in connection with such exchange or
        sale, without charge, at least one copy of the Registration Statement,
        as first filed with the Commission, and of each amendment thereto,
        including all documents incorporated by reference therein and all
        exhibits (including exhibits incorporated therein by reference);

               (viii) deliver to each Holder without charge, as many copies of
        the Prospectus (including each preliminary prospectus) and any amendment
        or supplement thereto as such Persons reasonably may request; the
        Issuers hereby consent to the use (in accordance with law) of the
        Prospectus and any amendment or supplement thereto by each selling
        Holder in connection with the offering and the sale of the Exchange
        Securities or the Transfer Restricted Securities covered by the
        Prospectus or any amendment or supplement thereto;

               (ix) upon the request of any Holder, enter into such agreements
        (including underwriting agreements) and make such representations and
        warranties and take all such other actions in connection therewith in
        order to expedite or facilitate the disposition of the Transfer
        Restricted Securities pursuant to any applicable Registration Statement
        contemplated by this Agreement as may be reasonably requested by any
        Holder in connection with any sale or resale pursuant to any applicable
        Registration Statement. In such connection, the Issuers shall:

                       (A) upon request of any Holder, furnish (or in the case
                of paragraphs (2) and (3), use their commercially reasonable
                best efforts to cause to be furnished) to each Holder, upon
                Consummation of the Exchange Offer or upon the effectiveness of
                the Shelf Registration Statement, as the case may be:

                               (1) a certificate, dated such date, signed on
                        behalf of the Issuers by (x) the President or any Vice
                        President, or in the case of the Guarantor and

                                       11

                        DGmbH (as defined in the Purchase Agreement) members of
                        the board (Vorstand or Geschaftsfuhrung), as the case
                        may be, and (y) a principal financial or accounting
                        officer of such Issuer, confirming, as of the date
                        thereof, the matters set forth in Sections 6(y)(iv),
                        9(a) and 9(b) of the Purchase Agreement and such other
                        similar matters as such Holders may reasonably request;

                               (2) an opinion, dated the date of Consummation
                        of the Exchange Offer or the date of effectiveness of
                        the Shelf Registration Statement, as the case may be, of
                        counsel for the Issuers covering matters similar to
                        those set forth in paragraph (f) of Section 9 of the
                        Purchase Agreement and as to the effectiveness of the
                        Registration Statement, the absence of stop orders with
                        respect thereto and compliance of the Registration
                        Statement as to form with the requirements of the
                        Securities Act and the TIA and in any event including a
                        statement substantially to the effect that such counsel
                        has participated in conferences with officers and other
                        representatives of the Issuers, representatives of the
                        independent public accountants for the Guarantor
                        regarding the Registration Statement and the Prospectus
                        contained therein and have considered the matters
                        required to be stated therein and the statements
                        contained therein, although such counsel has not
                        independently verified the accuracy, completeness or
                        fairness of such statements; and that such counsel
                        advises that, on the basis of the foregoing (relying as
                        to materiality to the extent such counsel deems
                        appropriate upon the statements of officers and other
                        representatives of the Trust and the Guarantor) and
                        without independent check or verification), no facts
                        came to such counsel's attention that caused such
                        counsel to believe that the applicable Registration
                        Statement, at the time such Registration Statement or
                        any post-effective amendment thereto became effective
                        and, in the case of the Exchange Offer Registration
                        Statement, as of the date of Consummation of the
                        Exchange Offer, contained an untrue statement of a
                        material fact or omitted to state a material fact
                        required to be stated therein or necessary to make the
                        statements therein not misleading, or that the
                        Prospectus contained in such Registration Statement as
                        of its date and, in the case of the opinion dated the
                        date of Consummation of the Exchange Offer, as of the
                        date of Consummation, contained an untrue statement of a
                        material fact or omitted to state a material fact
                        necessary in order to make the statements therein, in
                        the light of the circumstances under which they were
                        made, not misleading. Without limiting the foregoing,
                        such counsel may state further that such counsel assumes
                        no responsibility for, and has not independently
                        verified, the accuracy, completeness or fairness of the
                        financial statements, notes and schedules and other
                        financial data included in any Registration Statement
                        contemplated by this Agreement or the related
                        Prospectus; and

                               (3) a customary comfort letter, dated the date
                        of Consummation of the Exchange Offer, or as of the date
                        of effectiveness of the Shelf

                        Registration Statement, as the case may be, from the
                        Guarantor's independent accountants, in the customary
                        form and covering matters of the type customarily
                        covered in comfort letters to underwriters in connection
                        with underwritten offerings, and affirming the matters
                        set forth in the comfort letters delivered pursuant to
                        Section 9(e) of the Purchase Agreement.

                        (B) deliver such other documents and certificates as may
                be reasonably requested by the selling Holders to such Persons
                to evidence compliance with the matters covered in clause (A)
                above and with any customary conditions contained in the any
                agreement entered into by the Issuers pursuant to this clause
                (ix);

                (x) prior to any public offering of Exchange Securities or
        Transfer Restricted Securities, cooperate with the selling Holders and
        their counsel in connection with the registration and qualification of
        the Exchange Securities or Transfer Restricted Securities under the
        state securities or Blue Sky laws of such jurisdictions within the
        United States as the selling Holders may request and do any and all
        other acts or things necessary or advisable to enable the disposition in
        such jurisdictions of the Exchange Securities or Transfer Restricted
        Securities covered by the applicable Registration Statement; provided,
        however, that none of the Issuers shall be required to register or
        qualify as a foreign corporation where it is not now so qualified or to
        take any action that would subject it to the service of process in suits
        or to taxation, other than as to matters and transactions relating to
        the Registration Statement, in any jurisdiction where it is not now so
        subject;

                (xi) in connection with any sale of Transfer Restricted
        Securities that will result in such securities no longer being Transfer
        Restricted Securities, cooperate with the Holders to facilitate the
        timely preparation and delivery of global certificates representing
        Transfer Restricted Securities to be sold and not bearing any
        restrictive legends; and to register such Transfer Restricted Securities
        in such denominations and such names as the selling Holders may request
        at least two Business Days prior to such sale of Transfer Restricted
        Securities;

                (xii) use their respective commercially reasonable best efforts
        to cause the disposition of the Transfer Restricted Securities covered
        by the Registration Statement to be registered with or approved by such
        other governmental agencies or authorities as may be necessary to enable
        the seller or sellers thereof to consummate the disposition of such
        Transfer Restricted Securities, subject to the proviso contained in
        clause (x) above;

                (xiii) provide a CUSIP number for all Exchange Securities or
        Transfer Restricted Securities, as the case may be, not later than the
        effective date of a Registration Statement covering such Transfer
        Restricted Securities and provide the Trustee under the Declaration with
        printed certificates for the Transfer Restricted Securities which are in
        a form eligible for deposit with the Depository Trust Company;

                (xiv) otherwise use their respective commercially reasonable
        best efforts to comply with all applicable rules and regulations of the
        Commission, and make generally

                                       13

        available to its security holders with regard to any applicable
        Registration Statement, as soon as practicable, a consolidated earnings
        statement meeting the requirements of Rule 158 to the Securities Act
        (which need not be audited) covering a twelve-month period beginning
        after the effective date of the Registration Statement (as such term is
        defined in paragraph (c) of Rule 158 under the Securities Act);

                (xv) cause the Declaration and the Indenture to be qualified
        under the TIA not later than the effective date of the first
        Registration Statement required by this Agreement and, in connection
        therewith, cooperate with the Trustee and the Holders to effect such
        changes to the Declaration and the Indenture as may be required for such
        Declaration or Indenture to be so qualified in accordance with the terms
        of the TIA; and execute and use their best efforts to cause the Trustee
        to execute, all documents that may be required to effect such changes
        and other forms and documents required to be filed with the Commission
        to enable such Declaration or Indenture to be so qualified in a timely
        manner;

               (xvi) provide promptly to each Holder, upon request, each
        document filed with the Commission pursuant to the requirements of
        Section 13 or Section 15(d) of the Exchange Act; and

               (xvii) to use their commercially reasonable best efforts to
        cause the Exchange Securities to be listed on the Luxembourg Stock
        Exchange.

               (d) Restrictions on Holders. Each Holder agrees by acquisition of
a Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(iii)(C) or any notice from the Trust of the existence of any fact
of the kind described in Section 6(c)(iii)(D) hereof (in each case, a
"Suspension Notice"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration Statement
until (i) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is
advised in writing by the Trust that the use of the Prospectus may be resumed,
and has received copies of any additional or supplemental filings that are
incorporated by reference in the Prospectus (in each case, the "Recommencement
Date"). Each Holder receiving a Suspension Notice hereby agrees that it will
either (i) destroy any Prospectuses, other than permanent file copies, then in
such Holder's possession which have been replaced by the Trust with more
recently dated Prospectuses or (ii) deliver to the Trust (at the Trust's
expense) all copies, other than permanent file copies, then in such Holder's
possession of the Prospectus covering such Transfer Restricted Securities that
was current at the time of receipt of the Suspension Notice. The time period
regarding the effectiveness of such Registration Statement set forth in Sections
3 or 4 hereof, as applicable, shall be extended by a number of days equal to the
number of days in the period from and including the date of delivery of the
Suspension Notice to the date of delivery of the Recommencement Date.

SECTION 7. REGISTRATION EXPENSES

               (a) All expenses incident to the Issuers' performance of or
compliance with this Agreement will be borne by the Guarantor, regardless of
whether a Registration Statement becomes effective, including without
limitation: (i) all registration and filing fees and expenses;

                                       14
<PAGE>   16

(ii) all fees and expenses of compliance with federal securities and state Blue

printing of Prospectuses, messenger and delivery services and telephone; (iv)
all fees and disbursements of counsel for the Issuers; (v) all application and
filing fees in connection with a listing of the Exchange Securities on the
Luxembourg Stock Exchange; and (vi) all fees and disbursements of independent
certified public accountants of the Trust and the Guarantor (including the
expenses of any special audit and comfort letters required by or incident to
such performance).

               The Trust will, in any event, bear its and the Guarantor's
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expenses
of any annual audit and the fees and expenses of any Person, including special
experts, retained by the Trust or the Guarantor.

               (b) In connection with any Registration Statement required by
this Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Guarantor will reimburse
the Initial Purchasers and the Holders of Transfer Restricted Securities who are
tendering Securities into the Exchange Offer and/or selling or reselling
Securities or Exchange Securities pursuant to the "Plan of Distribution"
contained in the Exchange Offer Registration Statement or the Shelf Registration
Statement, as applicable, for the reasonable fees and disbursements of not more
than one counsel, who shall be Shearman & Sterling, 9 Appold Street, London EC2A
2AP, unless another firm shall be chosen by the Holders of a majority in
liquidation amount of the Transfer Restricted Securities for whose benefit such
Registration Statement is being prepared.

SECTION 8. INDEMNIFICATION

               (a) The Issuers agree, jointly and severally, to indemnify and
hold harmless each Holder, its directors, officers and each Person, if any, who
controls such Holder (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act), from and against any and all losses, claims,
damages, liabilities, judgments, (including without limitation, any legal or
other expenses incurred in connection with investigating or defending any
matter, including any action that could give rise to any such losses, claims,
damages, liabilities or judgments) caused by any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement,
preliminary prospectus or Prospectus (or any amendment or supplement thereto)
provided by the Trust to any Holder or any prospective purchaser of Exchange
Securities or registered Securities, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by an untrue
statement or omission or alleged untrue statement or omission that is based upon
information relating to any of the Holders furnished in writing so the Trust by
any of the Holders.

               (b) Each Holder of Transfer Restricted agrees, severally and not
jointly, to indemnify and hold harmless the Issuers, and their respective
directors and officers, and each person, if any, who controls (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
any Issuer, to the same extent as the foregoing indemnity from the Issuers

                                       15
<PAGE>   17

set forth in section (a) above, but only with reference to information relating
to such Holder furnished in writing to the Trust by such Holder expressly for
use in any Registration Statement. In no event shall any Holder, its directors,
officers or any Person who controls such Holder be liable or responsible for any
amount in excess of the amount by which the total amount received by such Holder
with respect to its sale of Transfer Restricted Securities pursuant to a
Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages that such
Holder, its directors, officers or any Person who controls such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

               (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and,
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all indemnified parties and all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by a majority of the
Holders, in the case of the parties indemnified pursuant to Section 8(a), and by
the Guarantor, in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against any and all losses, claims, damages, liabilities and judgments by
reason of any settlement of any action (i) effected with the indemnifying
party's written consent or (ii) effected without the indemnifying party's
written consent if the settlement is entered into more than twenty business days
after the indemnifying party shall have received a request from the indemnified
party for reimbursement for the fees and expenses of counsel (in any case where
such fees and expenses are at the expense of the indemnifying party) and, prior
to the date of such settlement, the indemnifying party shall have failed to
comply with such reimbursement request. No indemnifying party shall, without the
prior

                                       16
<PAGE>   18

written consent of the indemnified party, effect any settlement or compromise
of, or consent to the entry of judgment with respect to, any pending or
threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action 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 the indemnified party.

               (d) To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments (i) in such proportion
as is appropriate to reflect the relative benefits received by the Issuers, on
the one hand, and the Holders, on the other hand, from their sale of Transfer
Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause 8(d)(i) above but also the
relative fault of the Issuers, on the one hand, and of the Holder, on the other
hand, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative fault of the Issuers, on the one hand,
and of the Holder, 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 Issuers, on the one hand, or by the Holder, on the
other hand, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

               The Issuers and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any matter, including any
action that could have given rise to such losses, claims, damages, liabilities
or judgments. Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any Person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds (i) the
amount paid by such Holder for such Transfer Restricted Securities and (ii) the
amount of any damages which such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. 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 who was not guilty of such fraudulent misrepresentation. The Holders'
obligations to contribute pursuant to this Section 8(d) are several in
proportion to the

                                       17
<PAGE>   19

respective liquidation amount of Transfer Restricted Securities held by each
Holder hereunder and not joint.

SECTION 9. RULE 144A AND RULE 144

               The Issuers agree with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Guarantor (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Securities Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

SECTION 10. MISCELLANEOUS

               (a) Remedies. The Issuers acknowledge and agree that any failure
by the Issuers to comply with their respective obligations under Sections 3 and
4 hereof may result in material irreparable injury to the Initial Purchasers or
the Holders for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Initial Purchasers or any Holder may obtain such relief
as may be required to specifically enforce the Issuers' obligations under
Sections 3 and 4 hereof. The Issuers further agree to waive the defense in any
action for specific performance that a remedy at law would be adequate.

               (b) No Inconsistent Agreements. None of the Issuers will, on or
after the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. Nothing in this
Agreement shall preclude or limit the Issuers from (i) conducting the Exchange
Offer pursuant to a single registration statement relating to both (A) the
Exchange Offer and (B) a substantially identical exchange offer relating to $225
million of United States dollar-denominated trust preferred securities (and
related trust guarantees, senior subordinated notes and note guaranties) having
substantially identical terms to the Securities (other than their currency,
their price in the initial offering, their coupon and the identity of the
issuer-trust) ("Dollar Exchange Offer") or (ii) preparing and filing a single
shelf registration statement with respect to both the Preferred Securities and
the additional trust preferred securities described in the preceding clause
(i)(B), and no actions taken pursuant to or as contemplated by this sentence
will be deemed inconsistent with the rights granted to the Holders in this
Agreement, it being understood that in the event that it is impracticable to
conduct the Exchange Offer and the Dollar Exchange Offer pursuant to a single
registration statement, each of the Exchange Offer and Dollar Exchange Offer
will proceed separately. Except for the agreement dated as of March 2, 2000
between the Guarantor and Persons who acquired non-voting Preference shares of
the Guarantor in the "Franconia" transaction and the A/B registration rights
agreement dated as of June 6, 2001 relating to the Dollar Exchange Offer, none
of the Issuers is a party to any agreement granting any registration rights with
respect to its securities to any person. The rights granted to the Holders

                                       18
<PAGE>   20

hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Issuer's securities of the Issuers under
any agreement in effect on the date hereof.

               (c) Amendments and Waivers. The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case of
Section 5 hereof and this Section 10(c)(i), the Trust has obtained the written
consent of Holders of all outstanding Transfer Restricted Securities and (ii) in
the case of all other provisions hereof, the Trust has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Trust or its Affiliates). Notwithstanding the foregoing, a waiver or consent to
departure from the provisions hereof that relates exclusively to the rights of
Holders whose Transfer Restricted Securities are being tendered pursuant to the
Exchange Offer, and that does not affect directly or indirectly the rights of
other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

               (d) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Issuers, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce such agreements directly to the extent they may deem such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

               (e) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery;

benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express
assignment, subsequent Holders; provided, that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms hereof or of the Purchase Agreement, the
Declaration or applicable law. If any transferee of any Holder shall acquire
Transfer Restricted Securities in any manner, whether by operation of law or
otherwise, such Transfer Restricted Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding such Transfer Restricted
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, including
the restrictions on resale set forth in this Agreement and, if applicable, the
Purchase Agreement, and such Person shall be entitled to receive the benefits
hereof.

               (g) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
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 GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO THE CONFLICT OF LAW RULES THEREOF.

               (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
