     (b)   Upon the effectiveness of the Exchange Offer Registration Statement,
           the Issuer and the Company shall promptly commence the Registered
           Exchange Offer, it being the objective of such Registered Exchange
           Offer to enable each Holder electing to exchange Securities for New

           without any limitations or restrictions under the Act and without
           material restrictions under the securities laws of a substantial
           proportion of the several states of the United States.

     (c)   In connection with the Registered Exchange Offer, the Issuer and the

        (ii)   keep the Registered Exchange Offer open for not less than 30 days
               after the date notice thereof is mailed to the Holders (or longer
               if required by applicable law);

        (iii)  utilize the services of a depositary for the Registered Exchange
               Offer with an address in the Borough of Manhattan, The City of
               New York; and

        (iv)  comply in all respects with all laws of the United States,
              Luxembourg, The Netherlands and Poland applicable to the
              Registered Exchange Offer.

     (d)   As soon as practicable after the close of the Registered Exchange
           Offer, the Issuer shall:

              validly withdrawn pursuant to the Registered Exchange Offer;

<PAGE>   4

        (iii)  cause the Trustee promptly to authenticate and deliver to each
               Holder of Securities, New Securities equal in principal amount to
               the Securities of such Holder so accepted for exchange.

     (e)   The Initial Purchasers, the Issuer and the Company acknowledge that,
           pursuant to interpretations by the Commission's staff of Section 5 of
           the Act, and in the absence of an applicable exemption therefrom,
           each Exchanging Dealer is required to deliver a Prospectus in
           connection with a sale of any New Securities received by such
           Exchanging Dealer pursuant to the Registered Exchange Offer in
           exchange for Securities acquired for its own account as a result of
           market-making activities or other trading activities. Accordingly,
           the Issuer and the Company shall:

        (i)   include the information set forth in Annex A hereto on the cover
              of the Exchange Offer Registration Statement, in Annex B hereto in
              the forepart of the Exchange Offer Registration Statement in a
              section setting forth details of the Exchange Offer, and in Annex
              C hereto in the underwriting or plan of distribution section of
              the Prospectus forming a part of the Exchange Offer Registration
              Statement, and include the information set forth in Annex D hereto
              in the Letter of Transmittal delivered pursuant to the Registered
              Exchange Offer; and

        (ii)   take all reasonable steps to keep the Exchange Offer Registration
               Statement continuously effective under the Act during the
               Exchange Offer Registration Period for delivery of the Prospectus
               contained therein by Exchanging Dealers in connection with sales
               of New Securities received pursuant to the Registered Exchange
               Offer, as contemplated by Section 4(h) below.

        The Issuer and the Company shall be deemed not to have taken all
        reasonable steps to keep the Exchange Offer Registration Statement
        effective during the Exchange Offer Registration Period if they
        voluntarily take any action that would result in Exchanging Dealers
        holding New Securities received in the Registered Exchange Offer being
        unable to offer and sell such securities during that period, unless (x)
        such action is required by applicable law, or (y) such action is taken
        by the Issuer or the Company in good faith and for valid business
        reasons (not including avoidance of the Issuer's or the Company's
        obligations hereunder), including the acquisition or divestiture of
        assets, so long as the Issuer and the Company promptly thereafter comply
        with the requirements of Section 4(k), if applicable.

     (f)   In the event that any Initial Purchaser determines that it is not
           eligible to participate in the Registered Exchange Offer with respect
           to the exchange of Securities constituting any portion of an unsold
           allotment, at the request of such Initial Purchaser, the Issuer and
           the Company shall as soon as possible issue and deliver to such
           Initial Purchaser, for distribution pursuant to a Shelf Registration
           Statement as contemplated by Section 3 hereof, or to the party
           purchasing New Securities registered under such Shelf Registration
           Statement, in exchange for such Securities, a like principal amount
           of New Securities. The Issuer and the Company shall seek to cause the
           CUSIP Service Bureau to issue the same CUSIP number for such New
           Securities as for New Securities issued pursuant to the Registered
           Exchange Offer.

     (g)   The Issuer and the Company shall submit the Exchange Offer
           Registration Statement or a Shelf Registration Statement, as the case
           may be, to the Securities Board not later than 90 days following the
           date of original issuance of the Securities and shall take all
           reasonable steps to cause the Securities Board to grant a
           dispensation with respect thereto so that the transfer restrictions
           imposed by Netherlands law shall cease to apply within 150 days after
           the date of original issuance of the Securities.

     3.  SHELF REGISTRATION.  If, (i) because of any change in law or applicable
interpretations thereof by the Commission's staff, the Issuer determines upon
advice of outside counsel that it is not permitted to effect the Registered
Exchange Offer as contemplated by Section 2 hereof, or (ii) if for any other
reason the Registered Exchange Offer is not consummated within 180 days after
the date of original issuance of the Securities, or (iii) if any Holder (other
than an Initial Purchaser) is not eligible under U.S. state or federal
securities laws to participate in the Registered Exchange Offer (other than
because such Holder is unable or unwilling to make the representation set forth
in Rider B to Annex D hereto) or (iv) any Initial Purchaser that holds any
Securities
<PAGE>   5

constituting any portion of an unsold allotment or otherwise acquired by such
Initial Purchaser in connection with the Initial Placement (or any New
Securities issued in exchange therefor in the Registered Exchange Offer to such
Initial Purchaser) so requests (it being understood that, for purposes of this
Section 3, (x) the requirement that an Initial Purchaser deliver a Prospectus
containing the information required by Items 507 and/or 508 of Regulation S-K
under the Act in connection with sales of New Securities acquired in exchange
for such Securities shall result in such New Securities being not "freely
tradeable" but (y) the requirement that an Exchanging Dealer deliver a
Prospectus in connection with sales of New Securities acquired in the Registered
Exchange Offer in exchange for Securities acquired as a result of market-making
activities or other trading activities shall not result in such New Securities
being not "freely tradeable"), the following provisions shall apply:

     (a)   The Issuer and the Company shall as promptly as practicable (but in
           no event more than 30 days after so required or requested pursuant to
           this Section 3), file with the Commission and thereafter shall take
           all reasonable steps to cause to be declared effective under the Act
           by the 180th day after the original issuance of the Securities a
           Shelf Registration Statement relating to the offer and sale of the
           Securities or the New Securities, as applicable, by the Holders from
           time to time in accordance with the methods of distribution elected
           by such Holders and set forth in such Shelf Registration Statement;
           provided, that with respect to New Securities received by an Initial
           Purchaser in exchange for Securities constituting any portion of an
           unsold allotment, the Issuer and the Company may, if permitted by
           current interpretations by the Commission's staff, file a
           post-effective amendment to the Exchange Offer Registration Statement
           containing the information required by Regulation S-K Items 507
           and/or 508, as applicable, in satisfaction of their obligations under
           this paragraph (a) with respect thereto, and any such Exchange Offer
           Registration Statement, as so amended, shall be referred to herein
           as, and governed by the provisions herein applicable to, a Shelf
           Registration Statement; provided, further, that the Company and the
           Issuer shall not be required to file more than one Shelf Registration
           Statement pursuant to this Agreement.

     (b)   The Issuer and the Company shall take all reasonable steps to keep
           the Shelf Registration Statement continuously effective in order to
           permit the Prospectus forming part thereof to be usable by Holders
           for a period from the date of its effectiveness until (i) two years
           from the Issue Date, (ii) if such Shelf Registration Statement is
           filed at the request of an Initial Purchaser, one year from the Issue
           Date, or (iii) if applicable, such shorter period that will terminate
           when all the Securities or New Securities, as applicable, covered by
           the Shelf Registration Statement have been sold pursuant to the Shelf
           Registration Statement (in any such case, such period being called
           the "Shelf Registration Period"). The Issuer and the Company shall be
           deemed not to have taken all reasonable steps to keep the Shelf
           Registration Statement effective during the requisite period if
           either of them voluntarily takes any action that would result in
           Holders of securities covered thereby not being able to offer and
           sell such securities during that period, unless (i) such action is
           required by applicable law, or (ii) such action is taken by the
           Company in good faith and for valid business reasons (not including
           avoidance of the Issuer's or the Company's obligations hereunder),
           including the acquisition or divestiture of assets, so long as the
           Issuer and the Company promptly thereafter comply with the
           requirements of Section 4(k) hereof, if applicable.

        (ii)   of any request by the Commission for amendments or supplements to
               the Registration Statement or the Prospectus included therein or
               for additional information.

           without charge, as many copies of the Prospectus included in such
           Exchange Offer Registration Statement and any amendment or supplement
           thereto as such Exchanging Dealer may reasonably request for delivery
           by such Exchanging Dealer in connection with a sale of New Securities
           received by it pursuant to the Registered Exchange Offer; and each of
           the Issuer and the Company consents to the use of such Prospectus or
           any amendment or supplement thereto by any such Exchanging Dealer in
           connection with the offering and sale of the New Securities covered
           by such Prospectus or any amendment or supplement thereto, as
           aforesaid.

     (i)   The Issuer and the Company shall register or qualify or cooperate
           with the Exchanging Dealers that are holders of New Securities
           covered by the Prospectus contemplated by Section 2(g) hereof and
           with the Holders of Securities registered on any Shelf Registration
           Statement and their Designated Counsel in connection with the
           registration or qualification of such securities for offer and sale
           under the securities or blue sky laws of such jurisdictions in the
           United States as any such Holders reasonably request in writing and
           do any and all other acts or things necessary or advisable to enable
           the offer and sale in such jurisdictions of the securities covered by
           such Registration Statement or Prospectus, as the case may be;
           provided, however, that neither the Issuer nor the Company will be
           required to qualify generally to do business in any jurisdiction
           where it is not then so qualified or to take any action which would
           subject it to general service of process or to taxation in any such
           jurisdiction where it is not then so subject.

     (j)   The Issuer and the Company shall cooperate with the Holders of
           Securities to facilitate the timely preparation and delivery of
           certificates representing Securities or New Securities, as the case
           may be, to be sold pursuant to any Registration Statement free of any
           restrictive legends and in such denominations (subject only to the
           provisions of the Indenture regarding minimum denominations) and
           registered in such names as Holders may request prior to sales of
           securities pursuant to such Registration Statement.

     (k)   Upon the occurrence of any event contemplated by paragraph
           (c)(2)(iii) above, the Issuer and the Company shall promptly prepare
           a post-effective amendment to any Registration Statement or an
           amendment or supplement to the related Prospectus or file any other
           required document so that, as thereafter delivered to purchasers of
           the Securities or New Securities, as the case may be, included
           therein, the Prospectus will not include 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.

     (1)   Not later than the effective date of any such Registration Statement
           hereunder, the Issuer and the Company shall provide a CUSIP number
           for the Securities or New Securities, as the case may be, registered
           under such Registration Statement, and provide the applicable trustee
           with printed certificates for such Securities or New Securities, in a
           form eligible for deposit with The Depository Trust Company.

     (m)  The Issuer and the Company shall take all reasonable steps to comply
          with all applicable rules and regulations of the Commission and the
          Securities Board and shall make generally available to Holders as soon
          as practicable after the effective date of the applicable Registration
          Statement an earnings statement (which need not be audited) satisfying
          the provisions of Section 11(a) under the Act.

     (n)   The Issuer and the Company shall cause the Indenture to be qualified
           under the Trust Indenture Act of 1939, as amended, in a timely
           manner.

     (o)   The Issuer and the Company may require each Holder of Securities to
           be sold pursuant to any Shelf Registration Statement to furnish to
           the Company such information regarding the Holder and the
           distribution of such securities as the Company may from time to time
           reasonably require for inclusion in such Registration Statement.
<PAGE>   8

     (p)   The Issuer and the Company shall promptly incorporate in a Prospectus
           supplement or post-effective amendment to a Shelf Registration
           Statement, such information as the Managing Underwriters and Majority
           Holders agree and reasonably request should be included therein and
           shall make all required filings of such Prospectus supplement or
           post-effective amendment as soon as notified of the matters to be
           incorporated in such Prospectus supplement or post-effective
           amendment.

     (q)   In the case of any Shelf Registration Statement, the Issuer and the
           Company shall, if requested by the Majority Holders, enter into such
           agreements (including underwriting agreements) and take all other
           appropriate actions in order to expedite or facilitate the
           registration or the disposition of the Securities, and in connection
           therewith, if an underwriting agreement is entered into, cause the
           same to contain indemnification provisions and procedures no less
           favorable than those set forth in Section 6 hereof (or such other
           provisions and procedures reasonably acceptable to the Majority
           Holders and the Managing Underwriters, if any, with respect to all
           parties to be indemnified pursuant to Section 6 hereof.

     (r)   In the case of any Shelf Registration Statement, the Issuer and the
           Company shall (i) make reasonably available for inspection by the
           Holders of Securities to be registered thereunder who shall certify
           to the Company that they have a current intent to sell such
           securities pursuant to such Registration Statement, any underwriter
           participating in any disposition pursuant to such Registration
           Statement, and any attorney, accountant or other agent retained by
           the Majority Holders or any such underwriter, all relevant financial
           and other records, pertinent corporate documents and properties of
           the Company and its subsidiaries; (ii) cause the Issuer's, the
           Company's and the Company's subsidiaries' officers, directors and
           employees to supply all relevant information reasonably requested by
           the Majority Holders or any such underwriter, attorney, accountant or
           agent in connection with any such Registration Statement as is
           customary for similar due diligence examinations; provided, however,
           that any information provided pursuant to clause (i) or clause (ii)
           hereof that is designated in writing by the Issuer or the Company, in
           good faith, as confidential at the time of delivery of such
           information shall be kept confidential by the Holders and any such
           underwriter, attorney, accountant or agent (from whom the Company and
           the Issuer shall be entitled to receive written confidentiality
           undertakings substantially to the same effect as those set forth in
           this Section 4(r)), unless such disclosure is required to be made in
           connection with a court proceeding pursuant to the subpoena or order
           of any court or other governmental agency or body having jurisdiction
           over the matter or is required by law (in which case such party shall
           promptly and prior to such disclosure notify the Company of such
           disclosure requirement and cooperate with the Company and the Issuer
           in seeking to stay or limit such disclosure requirement), or such
           information becomes available to the public generally or through a
           third party without an obligation of confidentiality; (iii) make such
           representations and warranties to the Holders of securities
           registered thereunder and the underwriters, if any, in form,
           substance and scope as are customarily made by issuers to
           underwriters in primary underwritten offerings and covering matters
           including, but not limited to, those set forth in the Purchase
           Agreement; (iv) obtain opinions of counsel to the Issuer, Holdings
           and the Company and updates thereof (which counsel and opinions (in
           form, scope and substance) shall be reasonably satisfactory to the
           Managing Underwriters, if any) addressed to each selling Holder and
           the underwriters, if any, covering such matters as are customarily
           covered in opinions requested in underwritten offerings and such
           other matters as may be reasonably requested by such Holders and
           underwriters; (v) obtain "cold comfort" letters and updates thereof
           from the independent certified public accountants of the Issuer and
           the Company (and, if necessary, any other independent certified
           public accountants of any subsidiary of the Issuer or the Company or
           of any business acquired by the Issuer, Holdings or the Company for
           which financial statements and financial data are, or are required to
           be, included in such Registration Statement), addressed to each
           selling Holder of securities registered thereunder and the
           underwriters, if any, in form and covering matters of the type
           customarily covered in "cold comfort" letters in connection with
           primary underwritten offerings; and (vi) deliver such documents and
           certificates as may be reasonably requested by the Majority Holders
           and the Managing Underwriters, if any, including those to evidence
           compliance with Section 4(k) hereof and with any customary conditions
           contained in the underwriting agreement or other agreement entered
           into by the Issuer, Holdings or
<PAGE>   9

        the Company. The foregoing actions set forth in clauses (iii), (iv), (v)
        and (vi) of this Section 4(r) shall be performed at (A) the
        effectiveness of such Registration Statement and each post-effective
        amendment thereto and (B) each closing under any underwriting or similar
        agreement as and to the extent required thereunder.

     (s)   In the case of any Exchange Offer Registration Statement, the Issuer
           and the Company shall (i) make reasonably available for inspection by
           each Exchanging Dealer, and any counsel, accountant or other agent
           retained by Exchanging Dealers holding a majority of the aggregate
           principal amount of New Securities for which delivery of a Prospectus
           as contemplated by Section 2(e) hereof is required, all relevant
           financial and other records, pertinent corporate documents and
           properties of the Company and its subsidiaries; (ii) cause the
           Issuer's, the Company's and the Company's subsidiaries' officers,
           directors and employees to supply all relevant information reasonably
           requested by such Exchanging Dealers or any such counsel, accountant
           or agent, in connection with any such Registration Statement as is
           customary for similar due diligence examinations; provided, however,
           that any information provided pursuant to clause (i) or clause (ii)
           hereof that is designated in writing by the Issuer or the Company, in
           good faith, as confidential at the time of delivery of such
           information shall be kept confidential by each Exchanging Dealer or
           any such counsel, accountant or agent (from whom the Company and the
           Issuer shall be entitled to receive written confidentiality
           undertakings substantially-to the same effect as those set forth in
           this Section 4(s)), unless such disclosure is made in connection with
           a court proceeding or required by law, or such information becomes
           available to the public generally or through a third party without an
           obligation of confidentiality; (iii) make such representations and
           warranties to such Exchanging Dealers, in form, substance and scope
           as are customarily made by issuers to underwriters in primary
           underwritten offerings and covering matters including, but not
           limited to, those set forth in the Purchase Agreement; (iv) obtain
           opinions of counsel to the Issuer, Holdings and the Company and
           updates thereof (which counsel and opinions (in form, scope and
           substance) shall be reasonably satisfactory to such Exchanging
           Dealers and such counsel), addressed to such Exchanging Dealers,
           covering such matters as are customarily covered in opinions
           requested in underwritten offerings and such other matters as may be
           reasonably requested by such Exchanging Dealers or such counsel; (v)
           obtain "cold comfort" letters and updates thereof from the
           independent certified public accountants of the Issuer, Holdings and
           the Company (and, if necessary, any other independent certified
           public accountants of any subsidiary of the Issuer or the Company or
           of any business acquired by the Issuer, Holdings or the Company for
           which financial statements and financial data are, or are required to
           be, included in the Registration Statement), addressed to such
           Exchanging Dealers, in customary form and covering matters of the
           type customarily covered in "cold comfort" letters in action with
           primary underwritten offerings, or if requested by such Exchanging
           Dealers or such counsel in lieu of a "cold comfort" letter, an
           agreed-upon procedures letter under Statement on Auditing Standards
           No. 35, covering matters requested by such Exchanging Dealers or such
           counsel; and (vi) deliver such documents and certificates as may be
           reasonably requested by such Exchanging Dealers or such counsel,
           including those to evidence compliance with Section 4(k) hereof and
           with conditions customarily contained in underwriting agreements. The
           foregoing actions set forth in clauses (iii), (iv), (v), and (vi) of
           this Section 4(s) shall be performed at the close of the Registered
           Exchange Offer and the effective date of any post-effective amendment
           to the Exchange Offer Registration Statement.

     5.  REGISTRATION EXPENSES.  The Issuer and the Company shall bear all
expenses incurred in connection with the performance of its obligations under
Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement
or any requirement for an Exchanging Dealer to deliver a Prospectus included in
the Exchange Offer Registration Statement, will reimburse the Holders for the
reasonable fees and disbursements of one firm or counsel designated by the
Majority Holders or by Exchanging Dealers holding a majority of the aggregate
principal amount of New Securities covered by such Prospectus, as the case may
be, to act as counsel for the Holders in connection therewith ("Designated
Counsel").

     6.  INDEMNIFICATION AND CONTRIBUTION.  (a) In connection with any
Registration Statement, the Issuer and the Company agree, and the Company agrees
to cause Holdings, to indemnify and hold harmless each Holder
<PAGE>   10

selling securities covered thereby (including with respect to any Prospectus
delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the
directors, officers, employees and agents of each such Holder and each person
who controls any such Holder within the meaning of either the Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Act, the
Exchange Act or other federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the Registration
Statement as originally filed or in any amendment thereof, or in any preliminary
Prospectus or Prospectus, or in any amendment thereof or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, and agrees, and the Company agrees to cause
Holdings, to reimburse each such indemnified party for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Issuer, Holdings and the Company will not be liable in any case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Issuer, Holdings or the Company by or on behalf of
any such Holder specifically for inclusion therein; provided, further, that
neither the Issuer nor Holdings nor the Company will be liable in any such case
to the extent that any such loss, claim, damage or liability arises out of or is
based on an untrue statement or omission in any Prospectus which was corrected
in a subsequent Prospectus where the relevant Exchanging Dealer sold the
securities to a person to whom it is established that such Exchanging Dealer
failed to send or otherwise deliver, at or prior to the written confirmation of
such sale, a copy of the subsequent Prospectus, as then amended or supplemented.
This indemnity shall not extend to any losses, damages, claims or other
liabilities that may result from the settlement or compromise by any indemnified
party of any action or claim, or any admission by such indemnified party of any
liability, in each case without the prior consent of the Company, which consent
shall not be unreasonably withheld or delayed. This indemnity agreement will be
in addition to any liability which the Issuer and the Company may otherwise
have.

     The Issuer and the Company also agree, if requested by the Majority
Holders, to enter into an underwriting agreement that includes an undertaking to
indemnify or contribute to Losses of, as provided in Section 6(d) hereof, any
underwriters of Securities registered under a Shelf Registration Statement,
their officers and directors and each person who controls such underwriters on
substantially the same basis as that of the indemnification of the selling
Holders provided in this Section 6(a), as provided in Section 4(q) hereof.

     (b)   Each Holder of securities covered by a Registration Statement
           (including with respect to any Prospectus delivery as contemplated in
           Section 4(h) hereof, each Exchanging Dealer) severally agrees to
           indemnify and hold harmless (i) the Issuer, (ii) the Company, (ii)
           Holdings, (iii) each of their respective directors, (iv) each of
           their respective officers who signs such Registration Statement and
           (v) each person who controls the Issuer, Holdings or the Company
           within the meaning of either the Act or the Exchange Act to the same
           extent as the foregoing indemnity from the Issuer, Holdings and the
           Company to each such Holder, but only with reference to written
           information relating to such Holder furnished to the Issuer, Holdings
           or the Company by or on behalf of such Holder specifically for
           inclusion in the documents referred to in the foregoing indemnity.
           This indemnity agreement will be in addition to any liability which
           any such Holder may otherwise have.

     (c)   Promptly after receipt by an indemnified party under this Section 6
           of notice of the commencement of any action, such indemnified party
           will, if a claim in respect thereof is to be made against the
           indemnifying party under this Section 6, notify the indemnifying
           party in writing of the commencement thereof; but the failure so to
           notify the indemnifying party (i) will not relieve it from liability
           under paragraph (a) or (b) above unless and to the extent such
           failure results in the forfeiture by the indemnifying party of
           substantial rights and defenses and (ii) will not, in any event,
           relieve the indemnifying party from any obligations to any
           indemnified party other than the indemnification obligation provided
           in paragraph (a) or (b) above. The indemnifying party shall be
           entitled to appoint counsel of the indemnifying party's choice at the
           indemnifying party's expense to represent the indemnified party in
           any action for which indemnification is sought (in which case the
           indemnifying
<PAGE>   11

        party shall not thereafter be responsible for the fees and expenses of
        any separate counsel retained by the indemnified party or parties except
        as set forth below); provided, however, that such counsel shall be
        reasonably satisfactory to the indemnified party. Notwithstanding the
        indemnifying party's election to appoint counsel to represent the
        indemnified party in an action, the indemnified party shall have the
        right to employ counsel (including local counsel) separate from counsel
        appointed by the indemnifying party, and the indemnifying party shall
        bear the reasonable fees, costs and expenses of such separate counsel
        (and local counsel) if (i) the use of counsel chosen by the indemnifying
        party to represent the indemnified party would present such counsel with
        a conflict of interest, (ii) the actual or potential defendants in, or
        targets of, any such action include both the indemnified party and the
        indemnifying party and the indemnified party shall have reasonably
        concluded that there may be legal defenses available to it and/or other
        indemnified parties which are different from or additional to those
        available to the indemnifying party, (iii) the indemnifying party shall
        not have employed counsel reasonably satisfactory to the indemnified
        party to represent the indemnified party within a reasonable time after
        notice of the institution of such action or (iv) the indemnifying party
        shall authorize the indemnified party to employ separate counsel at the
        expense of the indemnifying party. An indemnifying party will not,
        without the prior written consent of the indemnified parties (which
        consent shall not be unreasonably withheld), settle or compromise or
        consent to the entry of any judgment with respect to any pending or
        threatened claim, action, suit or proceeding in respect of which
        indemnification or contribution may be sought hereunder (whether or not
        the indemnified parties are actual or potential parties to such claim or
        action) unless such settlement, compromise or consent (i) includes an
        unconditional release of each indemnified party from all liability
        arising out of such claim, action, suit or proceeding and (ii) does not
        include a statement as to or an admission of fault, culpability or a
        failure to act, by or on behalf of any indemnified party.

     (d)   In the event that the indemnity provided in paragraph (a) or (b) of
           this Section 6 is unavailable to or insufficient to hold harmless an
           indemnified party for any reason, then each applicable indemnifying
           party, in lieu of indemnifying such indemnified party, shall have a
           joint and several obligation to contribute to the aggregate losses,
           claims, damages and liabilities (including legal or other expenses
           reasonably incurred in connection with investigating or defending
           same) (collectively "Losses") to which such indemnified party may be
           subject in such proportion as is appropriate to reflect the relative
           benefits received by such indemnifying party, on the one hand, and
           such indemnified party, on the other hand, from the Initial Placement
           and the Registration Statement which resulted in such Losses;
           provided, however, that in no case shall any Holder of any Security
           or New Security be responsible, in the aggregate, for any amount in
           excess of the purchase discount or commission applicable to such
           Security, or in the case of a New Security, applicable to the
           Security which was exchangeable into such New Security, as set forth
           on the cover page of the Final Memorandum, nor shall any underwriter
           be responsible for any amount in excess of the underwriting discount
           or commission applicable to the securities purchased by such
           underwriter under the Registration Statement which resulted in such
           Losses. If the allocation provided by the immediately preceding
           sentence is unavailable for any reason, the indemnifying party and
           the indemnified party shall contribute in such proportion as is
           appropriate to reflect not only such relative benefits but also the
           relative fault of such indemnifying party, on the one hand, and such
           indemnified party, on the other hand, in connection with the
           statements or omissions which resulted in such Losses as well as any
           other relevant equitable considerations. Benefits received by the
           Company shall be deemed to be equal to the total net proceeds from
           the Initial Placement (before deducting expenses) as set forth on the
           cover page of the Final Memorandum. Benefits received by the selling
           Holders shall be deemed to be equal to the value of receiving
           Securities or New Securities, as applicable, registered under the
           Act. Benefits received by any underwriter shall be deemed to be equal
           to the total underwriting discounts and commissions, as set forth on
           the cover page of the Prospectus forming a part of the Registration
           Statement which resulted in such Losses. Relative fault shall be
           determined by reference to whether any alleged untrue statement or
           omission relates to information provided by the indemnifying party,
           on the one hand, or by the indemnified party, on the other hand. The
           parties agree that it would not be just and equitable if contribution
           were determined by pro rata allocation or any other method of
           allocation which does not
<PAGE>   12

        take account of the equitable considerations referred to above.
        Notwithstanding the provisions of this paragraph (d), no person guilty
        of fraudulent misrepresentation (within the meaning of Section ll(f) of
        the Act) shall be entitled to contribution from any person who was not
        guilty of such fraudulent misrepresentation. For purposes of this
        Section 6, each person who controls a Holder within the meaning of
        either the Act or the Exchange Act and each director, officer, employee
        and agent of such Holder shall have the same rights to contribution as
        such Holder, and each person who controls the Issuer, Holdings or the
        Company within the meaning of either the Act or the Exchange Act, each
        officer of the Issuer, Holdings or the Company who shall have signed the
        Registration Statement and each director of the Issuer, Holdings or the
        Company shall have the same rights to contribution as the Issuer,
        Holdings and the Company, subject in each case to the applicable terms
        and conditions of this paragraph (d).

     (e)   The provisions of this Section 6 will remain in full force and
           effect, regardless of any investigation made by or on behalf of any
           Holder or the Issuer, Holdings or the Company or any of the officers,
           directors or controlling persons referred to in Section 6 hereof, and
           will survive the sale by a Holder of securities covered by a
           Registration Statement.

     7.  MISCELLANEOUS.

     (a)   No Inconsistent Agreements.  Each of the Issuer, the Company and the
           Company's subsidiaries has not, as of the date hereof, entered into,
           nor shall it, on or after the date hereof, enter into, any agreement
           with respect to its securities that is inconsistent with the rights
           granted to the Holders herein or otherwise conflicts with the
           provisions hereof.

     (b)   Amendments and Waivers.  The provisions of this Agreement, including
           the provisions of this sentence, may not be amended, qualified,
           modified or supplemented, and waivers or consents to departures from
           the provisions hereof may not be given, unless the Issuer or the
           Company has obtained the written consent of the Holders of at least a
           majority of the then outstanding aggregate principal amount of
           Securities (or, after the consummation of any Exchange Offer in
           accordance with Section 2 hereof, of New Securities); provided that,
           with respect to any matter that directly or indirectly affects the
           rights of any Initial Purchaser hereunder, the Issuer and the Company
           shall obtain the written consent of each such Initial Purchaser
           against which such amendment, qualification, supplement, waiver or
           consent is to be effective. Notwithstanding the foregoing (except the
           foregoing proviso), a waiver or consent to departure from the
           provisions hereof with respect to a matter that relates exclusively
           to the rights of Holders whose securities are being sold pursuant to
           a Registration Statement and that does not directly or indirectly
           affect the rights of other Holders may be given by the Majority
           Holders determined on the basis of securities being sold rather than
           registered under such Registration Statement.

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

        (1)   if to a Holder, at the address of such Holder maintained by the
              Registrar under the relevant Indenture;

        (2)   if to you or another Initial Purchaser, initially at the
              respective addresses set forth in the Purchase Agreement; and

        (3)   if to the Issuer, initially at its address set forth in the
              Purchase Agreement.

        (4)   if to the Company, initially at its address set forth in the
              Purchase Agreement.

        All such notices and communications shall be deemed to have been duly
        given when received.

        The Initial Purchasers, the Issuer or the Company by notice to the other
        may designate additional or different addresses for subsequent notices
        or communications.

     (d)   Successors and Assigns.  This Agreement shall inure to the benefit of
           and be binding upon the successors and permitted assigns of each of
           the parties, including, without the need for an express assignment or
           any consent by the Issuer or the Company thereto, subsequent Holders
           of Securities and/or New Securities. The Issuer and the Company
           hereby agree to extend the benefits of this Agreement to any Holder
           of Securities and/or New Securities and any such Holder may
           specifically enforce the provisions of this Agreement as if an
           original party hereto.

     (e)   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.

     (f)   Headings.  The headings in this agreement are for convenience or
           reference only and shall not limit or otherwise affect the meaning
           hereof.

     (g)   GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
           ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE
           TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE.

     (h)   Jurisdiction.  Each of the Issuer and the Company agrees that any
           suit, action or proceeding against the Issuer or the Company brought
           by any Initial Purchaser, the directors, officers, employees and
           agents of any Initial Purchaser, or by any person who controls any
           Initial Purchaser, arising out of or based upon this Agreement or the
           transactions contemplated hereby may be instituted in any state or
           federal court in the Borough of Manhattan, City of New York, New
           York, and waives any objection which it may now or hereafter have to
           the laying of venue of any such proceeding, and irrevocably submits
           to the nonexclusive jurisdiction of such courts in any suit, action
           or proceeding. Each of the Issuer and the Company has appointed CT
           Corporation System, with offices on the date hereof at 111 Eighth
           Avenue, New York, New York 10011, as its authorized agent (the
           "Authorized Agent"), upon whom process may be served in any suit,
           action or proceeding arising out of or based upon this Agreement or
           the transactions contemplated herein which may be instituted in any
           state or federal court in the Borough of Manhattan, City of New York,
           New York, by any Initial Purchaser, the directors, officers,
           employees and agents of any Initial Purchaser, or by any person, if
           any, who controls any Initial Purchaser, and expressly accepts the
           nonexclusive jurisdiction of any such court in respect of any such
           suit, action or proceeding. Each of the Issuer and the Company hereby
           represents and warrants that the Authorized Agent has accepted such
           appointment and has agreed to act as said agent for service of
           process, and each of the Issuer and the Company agrees to take any
           and all action, including the filing of any and all documents that
           may be necessary to continue such appointment in full force and
           effect as aforesaid. Service of process upon the Authorized Agent
           shall be deemed, in every respect, effective service of process upon
           the Issuer and the Company. Notwithstanding the foregoing, any action
           involving the Company arising out of or based upon this Agreement may
           be instituted by any Initial Purchaser, the directors, officers,
           employees and agents of any Initial Purchaser, or by any person who
           controls any Initial Purchaser in any court of competent jurisdiction
           in Luxembourg, The Netherlands or the Republic of Poland.

     (i)   Severability.  In the event that any one of more of the provisions
           contained herein, or the application thereof in any circumstances, is
           held valid, illegal or unenforceable in any respect for any reason,
           the validity, legality and enforceability of any such provision in
           every other respect and of the remaining provisions hereof shall not
           be in any way impaired or affected thereby, it being intended that
           all of the rights and privileges of the parties shall be enforceable
           to the fullest extent permitted by law.

     (j)   Securities Held by the Company, etc.  Whenever the consent or
           approval of Holders of a specified percentage of principal amount of
           Securities or New Securities is required hereunder, Securities or New
           Securities, as applicable, held by the Company or its Affiliates
           (other than subsequent Holders of Securities or New Securities if
           such subsequent Holders are deemed to be Affiliates solely by reason
           of their holdings of such Securities or New Securities) shall not be
           counted in determining whether such consent or approval was given by
           the Holders of such required percentage.
