                                       5
   7

            In connection with the Exchange Offer, the Company shall:

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

            (b) keep the Exchange Offer open for acceptance for a period of not
less than 30 calendar days after the date notice thereof is mailed to the
Holders (or longer if required by applicable law) (such period referred to
herein as the "Exchange Period");

            (c) utilize the services of the Depositary for the Exchange Offer,

            (d) permit Holders to withdraw tendered Registrable Securities at
any time prior to the expiration time of the Exchange Period. (Eastern Standard
Time), on the last business day of the Exchange Period, by sending to the
institution specified in the notice, a telegram, telex, facsimile transmission
or letter setting forth the name of such Holder, the principal, the principal
amount of Registrable Securities delivered for exchange, and a statement that
such Holder is withdrawing his election to have such Securities exchanged;

            (e) notify each Holder that any Registrable Security not tendered
will remain outstanding and continue to accrue interest, but will not retain any
rights under this Agreement (except in the case of the Initial Purchasers and
Participating Broker-Dealers as provided herein); and

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

            As soon as practicable after the close of the Exchange Offer, the
Company shall:

            (i) accept for exchange all Registrable Securities duly tendered and
      not validly withdrawn pursuant to the Exchange Offer in accordance with
      the terms of the Exchange Offer Registration Statement and the letter of
      transmittal which shall be an exhibit thereto;

            (ii) deliver to the Trustee for cancellation all Registrable
      Securities so accepted for exchange; and

            (iii) cause the Trustee promptly to authenticate and deliver
      Exchange Securities to each Holder of Registrable Securities so accepted
      for exchange in a principal amount


                                       6
   8

      equal to the principal amount of the Registrable Securities of such Holder
      so accepted for exchange.

            Interest on each Exchange Security will accrue from the most recent
interest payment date to which interest has been paid on the Registrable
Securities surrendered in exchange therefor or, if no interest has been paid on
the Registrable Securities, from the date of original issuance. The Exchange
Offer shall not be subject to any conditions, other than (i) that the Exchange
Offer, or the making of any exchange by a Holder, does not violate applicable
law or any applicable interpretation of the staff of the SEC, (ii) the due
tendering of Registrable Securities in accordance with the Exchange Offer, (iii)
that each Holder of Registrable Securities exchanged in the Exchange Offer shall
have represented that all Exchange Securities to be received by it shall be
acquired in the ordinary course of its business and that at the time of the
consummation of the Exchange Offer it shall have no arrangement or understanding
with any person to participate in the distribution (within the meaning of the
1933 Act) of the Exchange Securities and shall have made such other
representations as may be reasonably necessary under applicable SEC rules,
regulations or interpretations to render the use of Form S-4 or other
appropriate form under the 1933 Act available and (iv) that no action or
proceeding shall have been instituted or threatened in any court or by or before
any governmental agency with respect to the Exchange Offer which, in the
Company's judgment, would reasonably be expected to impair the ability of the
Company to proceed with the Exchange Offer. The Company shall inform the Initial
Purchasers of the names and addresses of the Holders to whom the Exchange Offer
is made, and the Initial Purchasers shall have the right to contact such Holders
and otherwise facilitate the tender of Registrable Securities in the Exchange
Offer.

            2.2. Shelf Registration. (i) If, because of any changes in law, SEC
rules or regulations or applicable interpretations thereof by the staff of the
SEC, the Company is not permitted to effect the Exchange Offer as contemplated
by Section 2.1 hereof, (ii) if for any other reason the Exchange Offer
Registration Statement is not declared effective within 120 calendar days
following the Closing Date or the Exchange Offer is not consummated within 150
calendar days after the Closing Date, (iii) upon the written request of any of
the Initial Purchasers with respect to any Registrable Securities which any of
them acquired directly from the Company or (iv) upon the written request of any
Holder that either (x) is not permitted pursuant to applicable law, SEC rules or
regulations or applicable interpretations thereof by the staff of the SEC to
participate in the Exchange Offer or (y) participates in the Exchange Offer and
does not receive fully tradable Exchange Securities pursuant to the Exchange
Offer, then in case of each of clauses (i) through (iv) the Company shall, at
its cost:

            (a) As promptly as practicable, file with the SEC, and thereafter
      shall use its best efforts to cause to be declared effective as promptly
      as practicable but no later than


                                       7
   9

      150 calendar days after the Closing Date, a Shelf Registration Statement
      relating to the offer and sale of the Registrable Securities by the
      Holders from time to time in accordance with the methods of distribution
      elected by the Majority Holders participating in the Shelf Registration
      and set forth in such Shelf Registration Statement.

            (b) Use its best efforts 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 of two years from the date
      the Shelf Registration Statement is declared effective by the SEC, or for
      such shorter period that will terminate when all Registrable Securities
      covered by the Shelf Registration Statement have been sold pursuant to the
      Shelf Registration Statement or cease to be outstanding or otherwise to be
      Registrable Securities.

            (c) Notwithstanding any other provisions hereof, use its best
      efforts to ensure that (i) any Shelf Registration Statement and any
      amendment thereto and any Prospectus forming part thereof and any
      supplement thereto complies in all material respects with the 1933 Act and
      the rules and regulations thereunder, (ii) any Shelf Registration
      Statement and any amendment thereto does not, when it becomes effective,
      contain an untrue statement of a material fact or omit to state a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading and (iii) any Prospectus forming part of any Shelf
      Registration Statement, and any supplement to such Prospectus (as amended
      or supplemented from time to time), does not include an untrue statement
      of a material fact or omit to state a material fact necessary in order to
      make the statements, in light of the circumstances under which they were
      made, not misleading.

            The Company further agrees, if necessary, to supplement or amend the
Shelf Registration Statement, as required by Section 3(b) below, and to furnish
to the Holders of Registrable Securities copies of any such supplement or
amendment promptly as reasonably practicable after its being used or filed with
the SEC.

            2.3. Expenses. The Company shall pay all Registration Expenses in
connection with the registration pursuant to Section 2.1 or 2.2. Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Securities
pursuant to the Shelf Registration Statement.

            2.4. Effectiveness. (a) The Company will be deemed not to have used
its best efforts to cause the Exchange Offer Registration Statement or the Shelf
Registration Statement,


                                       8
   10

as the case may be, to become, or to remain, effective during the requisite
period if the Company voluntarily takes any action that would, or omits to take
any action which omission would, result in any such Registration Statement not
being declared effective or in the holders of Registrable Securities covered
thereby not being able to exchange or offer and sell such Registrable Securities
during that period as and to the extent contemplated hereby, unless such action
is required by applicable law.

            (b) An Exchange Offer Registration Statement pursuant to Section 2.1
hereof or a Shelf Registration Statement pursuant to Section 2.2 hereof will not
be deemed to have become effective unless it has been declared effective by the
SEC; provided, however, that if, after it has been declared effective, the
offering of Registrable Securities pursuant to a Shelf Registration Statement is
interfered with by any stop order, injunction or other order or requirement of
the SEC or any other governmental agency or court, such Registration Statement
will be deemed not to have become effective during the period of such
interference, until the offering of Registrable Securities pursuant to such
Registration Statement may legally resume.

            2.5. Interest. The Indenture executed in connection with the
Securities will provide that in the event that either (a) the Exchange Offer
Registration Statement is not filed with the Commission on or prior to the 45th
calendar day following the Closing Date, (b) the Exchange Offer Registration
Statement has not been declared effective on or prior to the 120th calendar day
following the Closing Date, (c) the Exchange Offer is not consummated or, if
required, a Shelf Registration Statement is not declared effective, in either
case, on or prior to the 150th calendar day following the Closing Date or (d)
the Exchange Offer Registration Statement is declared effective but thereafter
ceases to be effective or usable (each such event referred to in clauses (a)
through (d) above, a "Registration Default"), the interest rate borne by the
Securities shall be increased by one-quarter of one percent per annum (0.25%)
upon the occurrence of each Registration Default, which rate will increase by
one-quarter of one percent (0.25%) each 90-day period that such additional
interest continues to accrue under any such circumstance, with an aggregate
maximum increase in the interest rate equal to one-half of one percent (0.50%)
per annum until such Registration Default has been cured. Upon (w) the filing of
the Exchange Offer Registration Statement after the 45-day period described in
clause (i) above, (x) the effectiveness of the Exchange Offer Registration
Statement after the 120-day period described in clause (ii) above, (y) the
consummation of the Exchange Offer or the effectiveness of a Shelf Registration
Statement, as the case may be, after the 150-day period described in clause
(iii) above, or (z) the cure of any Registration Default described in clause
(iv) above, the interest rate borne by the Securities from the date of such
filing, effectiveness, consummation or cure, as the case may be, will be reduced
to the original interest rate if the Company is otherwise in compliance with
this paragraph; provided, however, that if, after any 


                                       9
   11

such reduction in interest rate, a different event specified in clause (i),
(ii), (iii) or (iv) above occurs, the interest rate will again be increased
pursuant to the foregoing provisions.

            3. Registration Procedures. In connection with the obligations of
the Company with respect to Registration Statements pursuant to Sections 2.1 and
2.2 hereof, the Company shall:

            (a) prepare and file with the SEC a Registration Statement, within
      the relevant time period specified in Section 2, on the appropriate form
      under the 1933 Act, which form (i) shall be selected by the Company, (ii)
      shall in the case of a Shelf Registration, be available for the sale of
      the Registrable Securities by the selling Holders thereof, (iii) shall
      comply as to form in all material respects with the requirements of the
      applicable form and include or incorporate by reference all financial
      statements required by the SEC to be filed therewith or incorporated by
      reference therein, and (iv) shall comply in all respects with the
      requirements of Regulation S-T under the Securities Act, and use its best
      efforts to cause such Registration Statement to become effective and
      remain effective in accordance with Section 2 hereof;

            (b) prepare and file with the SEC such amendments and post-effective
      amendments to each Registration Statement as may be necessary under

      agreement or other similar agreement, if any, relating to the offering
      cease to be true and correct in all material respects, (v) of the
      happening of any event or the discovery of any facts during the period a
      Shelf Registration Statement is effective which makes any statement made
      in such Registration Statement or the related Prospectus untrue in any

      Registration Statement or Prospectus in order to make the statements
      therein not misleading and (vi) of the receipt by the Company of any

      activities and that will be the beneficial owner (as defined in Rule 13d-3
      under the Exchange Act) of Exchange Securities to be received by such
      broker-dealer in the Exchange Offer, whether such positions or policies
      have been publicly disseminated by the staff of the SEC or such positions
      or policies, in the reasonable judgment of the Initial Purchasers and its
      counsel, represent the prevailing views of the staff of the SEC, including
      a statement that any such broker-dealer who receives Exchange Securities
      for Registrable Securities pursuant to the Exchange Offer may be deemed a
      statutory underwriter and must deliver a prospectus meeting the
      requirements of the 1933 Act in connection with any resale of such

            Securities acquired for its own account as a result of market-making
            activities or other trading activities, it will deliver a prospectus
            meeting the requirements of the 1933 Act in connection with any
            resale of Exchange Securities received in respect of such
            Registrable Securities pursuant to the Exchange Offer;" and

      Company agrees to deliver to the Initial Purchasers on behalf of the

      customary form) at least as broad in scope and coverage as the comfort
      letter or comfort letters delivered to the Initial Purchasers in
      connection with the initial sale of the Securities to the Initial
      Purchasers;

            (g) (i) in the case of an Exchange Offer, furnish counsel for the

      Holders of Registrable Securities to facilitate the timely preparation and
      delivery of certificates representing Registrable Securities to be sold

      underwriters, if any, may reasonably request at least three business days
      prior to the closing of any sale of Registrable Securities;

            (k) in the case of a Shelf Registration, upon the occurrence of any
      event or the discovery of any facts, each as contemplated by Sections
      3(e)(v) and 3(e)(vi) hereof, use its best efforts to prepare a supplement
      or post-effective amendment to the Registration Statement or the related
      Prospectus or any document incorporated therein by reference or file any
      other required document so that, as thereafter delivered to the purchasers
      of the Registrable Securities or Participating Broker-Dealers, such
      Prospectus will not contain at the time of such delivery any untrue
      statement of a material fact or omit to state a material fact necessary to
      make the statements therein, in light of the circumstances under which
      they were made, not misleading or will remain so qualified;

      the filing of any Registration Statement, any Prospectus, any amendment to
      a Registration Statement or amendment or supplement to a Prospectus or any
      document which is to be incorporated by reference into a Registration
      Statement or a Prospectus after initial filing of a Registration
      Statement, provide copies of such document to the Initial Purchasers on
      behalf of such Holders; and make representatives of the Company as shall

      Initial Purchasers on behalf of such Holders, available for discussion of
      such document;

            (m) obtain a CUSIP number for all Exchange Securities or Registrable
      Securities, as the case may be, not later than the effective date of a

      be, in a form eligible for deposit with the Depositary;

            (n) (i) cause the Indenture to be qualified under the Trust
      Indenture Act of 1939 (the "TIA") in connection with the registration of
      the Exchange Securities or Registrable Securities, as the case may be,
      (ii) cooperate with the Trustee and the Holders to effect such changes to
      the Indenture as may be required for the Indenture to be so qualified in
      accordance with the terms of the TIA and (iii) execute, and use its best
      efforts to cause the Trustee to execute, all documents as may be required
      to effect such changes, and all other forms and documents required to be
      filed with the SEC to enable the Indenture to be so qualified in a timely
      manner;

            (o) in the case of a Shelf Registration, enter into agreements
      (including underwriting agreements) and take all other customary and
      appropriate actions in order to expedite or facilitate the disposition of
      such Registrable Securities and in such connection whether or not an
      underwriting agreement is entered into and whether or not the registration
      is an underwritten registration:

   16

            (i) make such representations and warranties to the Holders of such

            (ii) obtain opinions of counsel to the Company and updates thereof
      (which counsel and opinions (in form, scope and substance) shall be
      reasonably satisfactory to the managing underwriters, if any, and the

      being sold) addressed to each selling Holder and the underwriters, if any,
      covering the matters customarily covered in opinions requested in sales of
      securities or underwritten offerings and such other matters as may be
      reasonably requested by such Holders and underwriters;

      comfort" letters to underwriters in connection with similar underwritten
      offerings;

            (iv) enter into a securities sales agreement with the Holders and an
      agent of the Holders providing for, among other things, the appointment of
      such agent for the selling Holders for the purpose of soliciting purchases

      requested and as are customarily delivered in similar offerings to the

            (p) in the case of a Shelf Registration, make available for
      inspection by representatives of the Holders of the Registrable Securities

      requested by any such representative, underwriter, special counsel or
      accountant in connection with a Registration Statement, and make such
      representatives of the Company available for discussion of such documents
      as shall be reasonably requested by the Initial Purchasers;

            (q) (i) in the case of an Exchange Offer Registration Statement, a

      provide copies of such document to the Initial Purchasers and make such
      changes in any such document prior to the filing thereof as the Initial
      Purchasers may reasonably request and, except as otherwise required by
      applicable law, not file any such document in a form to which the Initial
      Purchasers on behalf of the Holders of Registrable Securities shall
      reasonably object, and make the representatives of the Company available

      Majority Holders or the Initial Purchasers on behalf of the Holders of
      Registrable Securities or any underwriter may reasonably object and make
      the representatives of the Company available for discussion of such
      document as shall be reasonably requested by the Holders of Registrable
      Securities, the Initial Purchasers on behalf of such Holders, or any
      underwriter.


                                       16
   18

            (r) otherwise use its best efforts to comply with all applicable
      rules and regulations of the SEC and make available to its security
      holders, as soon as reasonably practicable, an earnings statement covering
      at least 12 months which shall satisfy the provisions of Section 11(a) of
      the 1933 Act and Rule 158 thereunder;

            (s) cooperate and assist in any filings required to be made with the
      NASD and, in the case of a Shelf Registration, in the performance of any
      due diligence investigation by any underwriter and its counsel (including
      any "qualified independent underwriter" that is required to be retained in
      accordance with the rules and regulations of the NASD); and

            (t) upon consummation of an Exchange Offer, obtain a customary
      opinion of counsel to the Company addressed to the Trustee for the benefit
      of all Holders of Registrable Securities participating in the Exchange
      Offer, and which includes an opinion that (i) the Company has duly
      authorized, executed and delivered the Exchange Securities and the related
      indenture, and (ii) each of the Exchange Securities and related indenture
      constitute a legal, valid and binding obligation of the Company,
      enforceable against the Company in accordance with its respective terms
      (with customary exceptions).

            In the case of a Shelf Registration Statement, the Company may (as a
condition to such Holder's participation in the Shelf Registration) require each
Holder of Registrable Securities to furnish to the Company such information
regarding the Holder and the Proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing for use in connection with any Shelf Registration Statement or
Prospectus included therein, including, without limitation, information
specified in item 507 of Regulation S-K under the 1933 Act. Each Holder as to
which any Shelf Registration is being effected agrees to furnish promptly to the
Company all information required to be disclosed with respect to such Holder in
order to make any information with respect to such Holder previously furnished
to the Company by such Holder not materially misleading.

            In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
or the discovery of any facts, each of the kind described in Section 3(e)(v)
hereof, such Holder will forthwith discontinue disposition of Registrable
Securities pursuant to a Registration Statement until such Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
3(k) hereof, and, if so directed by the Company, such Holder will deliver to the
Company (at its expense) all copies in such Holder's possession, other than
permanent file copies then in such Holder's possession, of the Prospectus
covering such Registrable Securities current at the time of receipt of such
notice. If the Company shall give any such notice to


                                       17
   19

suspend the disposition of Registrable Securities pursuant to a Shelf
Registration Statement as a result of the happening of any event or the
discovery of any facts, each of the kind described in Section 3(e)(v) hereof,
the Company shall be deemed to have used its best efforts to keep the Shelf
Registration Statement effective during such period of suspension provided that
the Company shall use its best efforts to file and have declared effective (if
an amendment) as soon as practicable an amendment or supplement to the Shelf
Registration Statement and shall extend the period during which the Shelf
Registration Statement shall be maintained effective pursuant to this Agreement
by the number of days during the period from and including the date of the
giving of such notice to and including the date when the Holders shall have
received copies of the supplemented or amended Prospectus necessary to resume
such dispositions.

            In the event that the Company fails to effect the Exchange Offer or
file any Shelf Registration Statement and maintain the effectiveness of any
Shelf Registration Statement as provided herein, the Company shall not file any
Registration Statement with respect to any securities (within the meaning of
Section 2(l) of the 1933 Act) of the Company other than Registrable Securities.

            If any of the Registrable Securities covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the
underwriter or underwriters and manager or managers that will manage such
offering will be selected by the Majority Holders of such Registrable Securities
included in such offering and shall be acceptable to the Company. No Holder of
Registrable Securities may participate in any underwritten registration
hereunder unless such Holder (a) agrees to sell such Holder's Registrable
Securities on the basis provided in any underwriting arrangements approved by
the persons entitled hereunder to approve such arrangements and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements.

            4. Indemnification, Contribution. (a) The Company agrees to
indemnify and hold harmless the Initial Purchasers, each Holder, each
Participating Broker-Dealer, each Person who participates as an underwriter (any
such Person being an "Underwriter") and each Person, if any, who controls any
Holder or Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

            (i) against any and all loss, liability, claim, damage and expense
      whatsoever, as incurred, arising out of any untrue statement or alleged
      untrue statement of a material fact contained in any Registration
      Statement (or any amendment or supplement thereto) pursuant to which
      Exchange Securities or Registrable Securities were registered under the
      1933 Act, including all documents incorporated therein by reference, or
      the 


                                       18
   20

      omission or alleged omission therefrom of a material fact required to be
      stated therein or necessary to make the statements therein not misleading,
      or arising out of any untrue statement or alleged untrue statement of a
      material fact contained in any Prospectus (or any amendment or supplement
      thereto) or the omission or alleged omission therefrom of a material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading;

            (ii) against any and all loss, liability, claim, damage and expense
      whatsoever, as incurred, to the extent of the aggregate amount paid in
      settlement of any litigation, or any investigation or proceeding by any
      governmental agency or body, commenced or threatened, or of any claim
      whatsoever based upon any such untrue statement or omission, or any such
      alleged untrue statement or omission; provided that (subject to Section
      4(d) below) any such settlement is effected with the written consent of
      the Company; and

            (iii) against any and all expense whatsoever, as incurred (including
      the fees and disbursements of counsel chosen by any indemnified party as
      provided herein), reasonably incurred in investigating, preparing or
      defending against any litigation, or any investigation or proceeding by
      any governmental agency or body, commenced or threatened, or any claim
      whatsoever based upon any such untrue statement or omission, or any such
      alleged untrue statement or omission, to the extent that any such expense
      is not paid under subparagraph (i) or (ii) above; provided, however, that
      this indemnity agreement shall not apply to any loss, liability, claim,
      damage or expense to the extent arising out of any untrue statement or
      omission or alleged untrue statement or omission made in reliance upon and
      in conformity with written information furnished to the Company by the
      Initial Purchasers, such Holder or Underwriter expressly for use in a
      Registration Statement (or any amendment thereto) or any Prospectus (or
      any amendment or supplement thereto).

            (b) Each Holder severally, but not jointly, agrees to indemnify and
hold harmless the Company, the Initial Purchasers, each Underwriter and the
other selling Holders, and each of their respective directors and officers, and
each Person, if any, who controls the Company, the Initial Purchasers, any
Underwriter or any other selling Holder within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act, against any and all loss, liability,
claim, damage and expense described in the indemnity contained in Section 4(a)
hereof, as incurred, but only with respect to untrue statements or omissions, or
alleged untrue statements or omissions, made in the Shelf Registration Statement
(or any amendment thereto) or any Prospectus included therein (or any amendment
or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company expressly for use in the Shelf Registration
Statement (or any amendment thereto) or such Prospectus (or any 



                                       19
   21

amendment or supplement thereto); provided, however, that no such Holder shall
be liable for any claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
Shelf Registration Statement.

            (c) Each indemnified party shall give written notice as promptly as
reasonably practicable to each indemnifying party of any action or proceeding
commenced against it in respect of which indemnity may be sought hereunder, but
failure so to notify an indemnifying party shall not relieve such indemnifying
party from any liability hereunder to the extent it is not materially prejudiced
as a result thereof and in any event shall not relieve it from any liability
which it may have otherwise than on account of this indemnity agreement. An
indemnifying party may participate at its own expense in the defense of such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying party or parties be liable
for the fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 4 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

            (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.
Notwithstanding the immediately preceding sentence, if at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, an indemnifying party shall
not be liable for any settlement of the nature contemplated by Section 4(a)(ii)
effected without its consent if such indemnifying party (i) reimburses such
indemnified party in accordance with such request to the extent it considers


                                       20
   22

such request to be reasonable and (ii) provides written notice to the
indemnified party substantiating the unpaid balance as unreasonable, in each
case prior to the date of such settlement.

            (e) If the indemnification provided for in this Section 4 is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand, the
Holders on another hand, and the Initial Purchasers on another hand, from the
offering of the Securities, the Exchange Securities and the Registrable
Securities (taken together) included in such offering or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the Company on the one hand, the
Holders on another hand and the Initial Purchasers on another hand in connection
with the statements or omissions which resulted in such losses, liabilities,
claims, damages or expenses, as well as any other relevant equitable
considerations.

            The relative benefits received by the Company from the offering of
the Securities, the Exchange Securities and the Registrable Securities (taken
together) included in such offering shall in each case be deemed to include the
proceeds received by the Company in connection with the offering of the
Securities pursuant to the Purchase Agreement. The parties hereto agree that any
underwriting discount or commission or reimbursement of fees paid to the Initial
Purchasers pursuant to the Purchase Agreement shall not be deemed to be a
benefit received by the Initial Purchasers in connection with the offering of
the Exchange Securities or Registrable Securities included in such offering.

            The relative fault of the Company on the one hand, the Holders on
another hand, and the Initial Purchasers on another hand shall be determined by
reference to, among other things, whether any such untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Company, the Holders or the Initial
Purchasers and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

            The Company, the Holders and the Initial Purchasers agree that it
would not be just and equitable if contribution pursuant to this Section 4 were
determined by pro rata allocation (even if the Initial Purchasers 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 above in this
Section 4. The aggregate amount of losses, liabilities, claims, damages and


                                       21
   23

expenses incurred by an indemnified party and referred to above in this
Section 4 shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in investigating, preparing or defending
against any litigation, or any investigation or proceeding by any governmental
agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission.

            Notwithstanding the provisions of this Section 4, no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Securities sold by it were offered exceeds
the amount of any damages which such Initial Purchaser 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 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

            For purposes of this Section 4, each person, if any, who controls an
Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser or Holder, and each director of the Company, and each person,
if any, who controls the Company within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act shall have the same rights to contribution as
the Company. The Initial Purchasers' respective obligations to contribute
pursuant to this Section 7 are several in proportion to the principal amount of
Securities set forth opposite their respective names in Schedule A to the
Purchase Agreement and not joint.

            5.  Miscellaneous.

            5.1. Rule 144 and Rule 144A. For so long as the Company is subject
to the reporting requirements of Section 13 or 15 of the 1934 Act, the Company
covenants that it will file the reports required to be filed by it under the
1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules and
regulations adopted by the SEC thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the
request of any Holder of Registrable Securities (a) make publicly available such
information as is necessary to permit sales pursuant to Rule 144 under the 1933
Act, (b) deliver such information to a prospective purchaser as is necessary to
permit sales pursuant to Rule 144A under the 1933 Act, and (c) take such further
action that is reasonable in the circumstances, in each case, to the extent
required from time to time to enable such Holder to sell its Registrable
Securities without registration under the 1933 Act within the limitation of the
exemptions 


                                       22
   24

provided by (i) Rule 144 under the 1933 Act, as such Rule may be amended from
time to time, (ii) Rule 144A under the 1933 Act, as such Rule may be amended
from time to time, or (iii) any similar rules or regulations hereafter adopted
by the SEC. Upon the request of any Holder of Registrable Securities, the
Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

            5.2. No Inconsistent Agreements. The Company has not entered into
and the Company will not after the date of this Agreement enter into any
agreement which is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with the rights granted to the holders of the Company's other issued
and outstanding securities under any such agreements.

            5.3. Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure.

            5.4. Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (a) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 5.4, which address initially is the address set forth in the Purchase
Agreement with respect to the initial Purchasers; and (b) if to the Company,
initially at the Company's address set forth in the Purchase Agreement, and
thereafter at such other address of which notice is given in accordance with the
provisions of this Section 5.4.

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

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

            5.5. Successor and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees 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 Registrable
Securities in violation of the terms of the Purchase Agreement. If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement, 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.

            5.6. Third Party Beneficiaries. The Initial Purchasers (even if the
Initial Purchasers are not Holders of Registrable Securities) shall be third
party beneficiaries to the agreements made hereunder between the Company, on the
one hand, and the Holders, on the other hand, and shall have the right to
enforce such agreements directly to the extent they deem such enforcement
necessary or advisable to protect their rights or the rights of Holders
hereunder. Each Holder of Registrable Securities shall be a third party
beneficiary to the agreements made hereunder between the Company, 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 it deems such enforcement
necessary or advisable to protect its rights hereunder.

            5.7. 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.

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

            5.9. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICT OF LAWS THEREOF.

            5.10. 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 


                                       24
   26

respect and of the remaining provisions contained herein shall not be affected
or impaired thereby.


                                       25
   27

            IN WITNESS WHEREOF, the parties have executed this Agreement as of
the date first written above.

                                                                       Exhibit A


                           Form of Opinion of Counsel

            We are of the opinion that the Exchange Offer Registration Statement
and the Prospectus (other than the financial statements, notes or schedules
thereto and other financial data and supplemental schedules included or
incorporated by reference therein or omitted therefrom and the Form T-1, as to
which we need express no opinion), comply as to form in all material respects
with the requirements of the 1933 Act and the applicable rules and regulations
promulgated under the 1933 Act.

            In addition, we have participated in conferences with officers and
other representatives of the Company and the Note Guarantors, representatives of
the independent public accountants of the Company and the Note Guarantors and
representatives of the Initial Purchasers, at which the contents of the
Registration Statement and the Prospectus and related matters were discussed
and, although we are not passing upon, and do not assume any responsibility for,
the accuracy, completeness or fairness of the statements contained in the
Registration Statement and the Prospectus and have not made any independent
check or verification thereof, during the course of such participation, no facts
came to our attention that caused us to believe that the Registration Statement
or any amendment thereto, at the time the Registration Statement or any such
amendment became effective, 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 or any
amendment or supplement thereto, at the time the Prospectus was issued, at the
time any such amended or supplemented Prospectus was issued or at the Closing
Time, included or includes an untrue statement of a material fact or omitted or
omits 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; it being understood that we express no belief with respect to the
financial statements and schedules and other financial data included in the
Registration Statement and the Prospectus.
