the SEC, the Company and the Guarantors shall use their commercially reasonable
efforts to (i) cause to be filed an Exchange Offer Registration Statement
covering an offer to the Holders to exchange all the Registrable Securities for
Exchange Securities and (ii) have such Registration Statement remain effective

days after such effective date.

      The Company and the Guarantors shall commence the Exchange Offer by
mailing the related Prospectus, appropriate letters of transmittal and other
accompanying documents to each Holder stating, in addition to such other

(i)   that the Exchange Offer is being made pursuant to this Agreement and that
      all Registrable Securities validly tendered and not properly withdrawn
      will be accepted for exchange;

(ii)  the dates of acceptance for exchange (which shall be a period of at least
      20 Business Days from the date such notice is mailed) (the "Exchange
      Dates");

(iii) that any Registrable Security not tendered will remain outstanding and
      continue to accrue interest but will not retain any rights under this
      Agreement;

      to the Exchange Offer will be required to surrender such Registrable
      Security, together with the appropriate letters of transmittal, to the

      City of New York) and in the manner specified in the notice, prior to the
      close of business on the last Exchange Date; and

(v)   that any Holder will be entitled to withdraw its election, not later than
      the close of business on the last Exchange Date, by sending to the
      institution and at the address (located in the Borough of Manhattan, The
      City of New York) specified in the notice, a telegram, telex, facsimile
      transmission or letter setting forth the name of such Holder, the
      principal amount of Registrable Securities delivered for

                                       5
<PAGE>

      exchange and a statement that such Holder is withdrawing its election to
      have such Securities exchanged.

      As a condition to participating in the Exchange Offer, a Holder will be
required to represent to the Company and the Guarantors that (i) any Exchange
Securities to be received by it will be acquired in the ordinary course of its
business, (ii) at the time of commencement of the Exchange Offer it has no
arrangement or understanding with any Person to participate in the distribution
(within the meaning of the Securities Act) of the Exchange Securities, (iii) it
is not an "affiliate" (within the meaning of Rule 405 under Securities Act) of
the Company or any Guarantor and (iv) if such Holder is a broker-dealer that
will receive Exchange Securities for its own account in the Exchange Offer in
exchange for Securities that were acquired by such broker-dealer as a result of
market-making or other trading activities (a "Participating Broker-Dealer"),
then such Holder will deliver a Prospectus in connection with any resale of such
Exchange Securities.

      As soon as practicable after the last Exchange Date, the Company and the
Guarantors shall

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

(ii)  deliver, or cause to be delivered, to the Trustee for cancellation all
      Registrable Securities or portions thereof so accepted for exchange by the
      Company and issue, and cause the Trustee to promptly authenticate and
      deliver to each Holder, Exchange Securities equal in principal amount to
      the principal amount of the Registrable Securities surrendered by such
      Holder provided that, except as may be otherwise required by the
      Indenture, in the case of any Registrable Securities held in global form
      by a depositary, authentication and delivery to such depositary of one or
      more Exchange Securities in global form in an equivalent principal amount
      thereto for the account of such Holders in accordance with the Indenture
      shall satisfy such authentication and delivery requirement.

      The Company and the Guarantors shall use their commercially reasonable
efforts to complete the Exchange Offer as provided above and shall comply with
the applicable requirements of the Securities Act, the Exchange Act and other
applicable laws and regulations in connection with the Exchange Offer. The
Exchange Offer shall not be subject to any conditions, other than (i) that the
Exchange Offer does not violate any applicable law or applicable interpretations
of the Staff of the SEC and (ii) no action or proceeding shall have been
instituted or threatened in any court or by any governmental agency with respect
to the Exchange Offer.

            (b) In the event that (i) the Company and the Guarantors determine
that the Exchange Offer Registration provided for in Section 2(a) above is not
available

                                       6
<PAGE>

or may not be completed as soon as practicable after the last Exchange Date
because it would violate any applicable law or applicable interpretation of the
Staff of the SEC, (ii) the Exchange Offer is not for any other reason completed
by the 210th day after the Closing Date, or (iii) if any Initial Purchaser
holds any Securities acquired by it that have, or that are reasonably likely to
be determined to have, the status of an unsold allotment in an initial
distribution, and any such Initial Purchaser so requests in writing on or prior
to the 60th day after the consummation of the Exchange Offer, the Company and
the Guarantors shall use commercially reasonable efforts to cause to be filed as
soon as practicable after such determination, date or request, as the case may
be, a Shelf Registration Statement providing for the sale of all the Registrable
Securities by the Holders (or, in the case of clause (iii), any requesting
Initial Purchaser) thereof and to have such Shelf Registration Statement
declared effective by the SEC.

      In the event that the Company and the Guarantors are required to file a
Shelf Registration Statement pursuant to clause (iii) of the preceding sentence,
the Company and the Guarantors shall use commercially reasonable efforts to file
and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Registrable Securities
and a Shelf Registration Statement (which may be a combined Registration
Statement with the Exchange Offer Registration Statement) with respect to offers
and sales of Registrable Securities held by the Initial Purchasers after
completion of the Exchange Offer. Notwithstanding the foregoing, the Company and
the Guarantors may delay filing a Shelf Registration Statement, and any
amendment thereto, and may withhold efforts to cause such Shelf Registration
Statement, and any such amendment thereto, to become effective for a period of
up to 60 days, if (i) the Company determines in good faith that such Shelf
Registration Statement, and any such amendment thereto, might interfere with or
affect the negotiation or completion of any transaction that is being
contemplated by the Company (whether or not a final decision has been made to
undertake such transaction) at the time the right to delay is exercised or (ii)
such Shelf Registration Statement, and any such amendment thereto, would
otherwise require premature disclosure of non-public information that, in the
Company's judgment, exercised reasonably and in good faith, would have a
material adverse effect on or otherwise be detrimental to the Company; provided,
however, the Company may only exercise such right of delay or withholding of
efforts other than for purposes of avoiding its obligations under this
Agreement; provided further however, that the Company may not exercise such
right of delay or withholding of efforts more frequently than two times in any
12-month period and the aggregate period of any such delays or withholdings
shall not exceed 60 days in any such 12-month period.

      The Company and the Guarantors agree to use commercially reasonable
efforts to keep the Shelf Registration Statement continuously effective until
all of the Registrable Securities covered thereby are eligible for resale under
Rule 144(k) under the Securities Act upon the expiration of the time period
referred to in such rule or such earlier

                                       7
<PAGE>

time when all the Registrable Securities covered by the Shelf Registration
Statement have been sold pursuant to the Shelf Registration Statement (the
"Shelf Effectiveness Period"). The Company and the Guarantors further agree to
supplement or amend the Shelf Registration Statement and the related Prospectus
if required by the rules, regulations or instructions applicable to the
registration form used by the Company and the Guarantors for such Shelf
Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registration or if reasonably requested by a
Holder of Registrable Securities with respect to information relating to such
Holder, and to use commercially reasonable efforts to cause any such amendment
to become effective and such Shelf Registration Statement and Prospectus to
become usable as soon as thereafter practicable. The Company and the Guarantors
agree to furnish to the Holders of Registrable Securities covered by any such
Shelf Registration Statement copies of any such supplement or amendment promptly
after its being used or filed with the SEC.

            (c) The Company and the Guarantors shall pay all Registration Ex
penses in connection with the registration pursuant to Section 2(a) and Section
2(b) hereof. 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 Exchange Offer Registration Statement or
Shelf Registration Statement.

            (d) An Exchange Offer Registration Statement pursuant to Section
2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof
will not be deemed to have become effective unless it has been declared
effective by the SEC.

      In the event that (i) either the Exchange Offer is not completed or a
Shelf Registration Statement required under Section (2)(b)(i) or (ii) hereof is
not declared effective on or prior to the 210th day after the Closing Date (the
"Target Registration Date") or (ii) a Shelf Registration Statement required
under Section 2(b)(iii) hereof is not declared effective on or prior to the 60th
day following the Filing Date (also a "Target Registration Date"), the interest
rate on the Registrable Securities will be increased by (i) 0.25% per annum for
the first 90-day period immediately following the applicable Target Registration
Date and (ii) an additional 0.25% per annum with respect to each subsequent
90-day period, in each case until the Exchange Offer is completed or the Shelf
Registration Statement, if required hereby, is declared effective by the SEC or
the Securities covered thereby are eligible for resale under Rule 144(k) under
the Securities Act upon the expiration of the time period referred to in such
rule; provided however, that in no event shall the aggregate amount of
additional interest accruing under this paragraph exceed in the aggregate 1.00%
per annum.

      If the Shelf Registration Statement has been declared effective and
thereafter either ceases to be effective or the Prospectus contained therein
ceases to be usable at

                                       8
<PAGE>

any time during the Shelf Effectiveness Period, and such failure to remain
effective or usable exists for more than 60 days (whether or not consecutive) in
any 12-month period, then the interest rate on the Registrable Securities will
be increased by 1.00% per annum commencing on the 61st day in such 12-month
period and ending on such date that the Shelf Registration Statement has again
been declared effective or the Prospectus again becomes usable.

      In no event shall the Company or Guarantors be obligated to pay additional
interest under more than one provisions of this Section 2(d) at any one time.
Upon the effectiveness of the Exchange Offer Registration Statement or the Shelf
Registration Statement (in the case of clauses (i) and (ii) of the second
paragraph of this Section 2(d), as applicable) or the Shelf Registration
Statement which had ceased to remain effective (in the case of the penultimate
paragraph of this Section 2(d)), or the Securities become eligible for sale
pursuant to Rule 144(k) under the Securities Act upon the expiration of the
time period referred to in such rule (in the case of the second and third
paragraphs of this Section 2(d)), additional interest on the Securities as a
result of such provisions (or the relevant subclause thereof), as the case may
be, shall cease to accrue.

            (e) Without limiting the remedies available to the Initial
Purchasers and the Holders, the Company and the Guarantors acknowledge that any
failure by the Company or the Guarantors to comply with their obligations under
Section 2(a) and Section 2(b) hereof may result in material irreparable injury
to the Initial Purchasers or the Holders for which there is no adequate remedy
at law, that it will not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, the Initial Purchasers or
any Holder may obtain such relief as may be required to specifically enforce
the Company's and the Guarantors' obligations under Section 2(a) and Section
2(b) hereof.

            (f) No Holder of Registrable Securities may include any of its
Regis- trable Securities in any Shelf Registration if such Holder shall have
failed to furnish to the Company the information with respect to such Holder and
the proposed disposition specified in Items 507 and 508 (as applicable) of
Regulation S-K under the Securities Act and any other applicable rules,
regulations or policies of the SEC for use in connection with any Shelf
Registration or Prospectus included therein. No Holder of Registrable
Securities shall be entitled to additional interest pursuant to Section 2(b) if
such Holder shall have failed to provide all such information. Each selling
Holder as to which a Shelf Registration is being effected agrees to furnish
promptly to the Company additional information to be disclosed so that the
information previously furnished to the Company by such Holder does not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statement therein not
misleading.

            3. Registration Procedures. In connection with their obligations
pursuant to Section 2(a) and Section 2(b) hereof, the Company and the Guarantors
shall as expeditiously as possible:

      propriate form under the Securities Act, which form (x) shall be selected

      be included therein by the selling Holders thereof and (z) shall comply as
      to form in all material respects with the requirements of the applicable
      form and include all financial statements required by the SEC to be filed
      therewith; and use commercially reasonable efforts to cause such
      Registration Statement to become effective and remain effective for the
      applicable period 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 to keep such

      re quired prospectus supplement and, as so supplemented, to be filed
      pursuant to Rule 424 under the Securities Act; and keep each Prospectus
      current during the period described in Section 4(3) of and Rule 174 under
      the Securities Act that is applicable to transactions by brokers or
      dealers with respect to the Registrable Securities or Exchange Securities;

            (c) in the case of a Shelf Registration, furnish to each Holder of
      Registrable Securities covered thereby, to counsel for the Initial
      Purchasers, to counsel for such Holders and to each Underwriter of an
      Underwritten Offering of Registrable Securities, if any, without charge,
      as many copies of each Prospectus, including each preliminary
      Prospectus, and any amendment or supplement thereto, as may be reasonably
      requested in order to facilitate the sale or other disposition of the
      Registrable Securities covered thereunder; and the Company and the
      Guarantors consent to the use of such Prospectus and any amendment or
      supplement thereto in accordance with applicable law by each of the
      selling Holders of Registrable Securities and any such Underwriters in
      connection with the offering and sale of the Registrable Securities
      covered by and in the manner described in such Prospectus or any amendment
      or supplement thereto in accordance with applicable law;

            (d) use commercially reasonable efforts to register or qualify the
      Registrable Securities under all applicable state securities or blue sky
      laws of such jurisdictions in the United States of America as any Holder
      of Registrable Securities covered by a Registration Statement shall
      reasonably request in writing by

                                       10
<PAGE>

      the time the applicable Registration Statement is declared effective by
      the SEC; cooperate with the Holders in connection with any filings
      required to be made with the National Association of Securities Dealers,
      Inc.; and do any and all other acts and things that may be reasonably
      necessary or advisable to enable each Holder to complete the disposition
      in each such jurisdiction of the Registrable Securities owned by such
      Holder; provided that neither the Company nor any Guarantor shall be
      required to (i) qualify as a foreign corporation or other entity or as a

      be required to so qualify, (ii) file any general consent to service of

      proceedings for that purpose, (iv) if, between the effective date of a
      Registration Statement and the closing of any sale of Registrable
      Securities covered thereby, the representations and warranties of the
      Company or any Guarantor contained in any underwriting agreement,
      securities sales agreement or other similar agreement, if any, relating to
      an offering of such Registrable Securities cease to be true and correct in
      all material respects or if the Company or any Guarantor receives any
      notification with respect to the suspension of the qualification of the
      Registrable Securities for sale in any jurisdiction or the initiation of
      any proceeding for such purpose, (v) of the happening of any event during
      the period a Shelf Registration Statement is effective that makes any
      statement made in such Registration Statement or the related Prospectus
      untrue in any material respect or that requires the making of any changes
      in such Registration Statement or Prospectus in order to make the
      statements therein not misleading and of the delay in filing a Shelf
      Registration Statement, or any amendment thereto, or of the withholding of
      efforts to cause such Shelf Registration Statement, or any such amendment
      thereto, to become effective, pursuant to the third sentence of Section
      2(b) and (vi) of any determination by the Company or any Guarantor that a
      post-effective amendment to a Registration Statement would be appropriate;
      provided that, in the case of clause (iv), (v) or (vi), with respect to
      any event, development or transaction that would permit the Company to
      exercise its rights of

                                       11
<PAGE>

      delay or withholding of efforts under the third sentence of Section 2(b),
      the Company shall provide written notice that, in its good faith judgment,
      such an event, development or transaction has occurred or is pending and
      that it is exercising its rights of delay or withholding of efforts
      pursuant to the third sentence of Section 2(b) of this Agreement; provided
      further that the Company shall not be required to describe such event,
      development or transaction in the written notice provided.

            (f) use their commercially reasonable efforts to obtain the
      withdrawal of any order suspending the effectiveness of a Registration
      Statement at the earliest possible moment and provide immediate notice to
      each Holder of the withdrawal of any such order;

            (g) in the case of a Shelf Registration, furnish to each Holder of
      Registrable Securities covered thereby, without charge, at least one
      conformed copy of each Registration Statement and any post-effective
      amendment thereto (without any documents incorporated therein by reference
      or exhibits thereto, unless requested);

            (h) in the case of a Shelf Registration, cooperate with the selling
      Holders of Registrable Securities covered thereby to facilitate the timely
      preparation and delivery of certificates representing Registrable
      Securities to be sold and not bearing any restrictive legends and enable
      such Registrable Securities to be issued in such denominations and
      registered in such names (consistent with the provisions of the Indenture)
      as the selling Holders may reasonably request at least one Business Day
      prior to the closing of any sale of Registrable Securities;

            (i) subject to the third sentence of Section 2(b), in the case of a
      Shelf Registration, upon the occurrence of any event contemplated by
      Section 3(e)(v) hereof, use their commercially reasonable efforts to
      prepare and file with the SEC a supplement or post-effective amendment to
      a 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 purchasers of the Registrable Securities,
      such Prospectus will not contain any untrue statement of a material fact
      or omit to state a material fact necessary to make the statements therein,
      in the light of the circumstances under which they were made, not
      misleading; and the Company and the Guarantors shall notify the Holders of
      Registrable Securities covered by such Shelf Registration to suspend use
      of the Prospectus as promptly as practicable after the occurrence of such
      an event, and such Holders hereby agree to suspend use of the Prospectus
      until the Company and the Guarantors have amended or supplemented the
      Prospectus to correct such misstatement or omission and expressly agree to
      maintain the information contained in such notice confidential (except
      that such information may be dis-

                                       12
<PAGE>

      closed to their counsel) until it has been publicly disclosed by the
      Company; provided that, with respect to any event, development or
      transaction that would permit the Company and the Guarantors to exercise
      their rights of delay or withholding of efforts under the third sentence
      of Section 2(b), such notice shall state that, in the Company's good faith
      judgment, such an event, development or transaction has occurred or is
      pending and that it is exercising its rights of delay or withholding of
      efforts pursuant to the third sentence of Section 2(b) of this Agreement;
      provided further that the Company shall not be required to describe such
      event, development or transaction in such notice.

            (j) a reasonable time prior to the filing of any Registration
      Statement, any Prospectus, any amendment to a Registration Statement or
      amendment or supplement to a Prospectus or of any document that 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 and their counsel (and, in the case of
      a Shelf Registration Statement, to the Holders of Registrable Securities
      covered thereby and their counsel) and make such of the representatives of
      the Company and the Guarantors as shall be reasonably requested by the
      Initial Purchasers or their counsel (and, in the case of a Shelf
      Registration Statement, the Holders of such Registrable Securities or
      their counsel) available for discussion of such document; and the Company
      and the Guarantors shall not, at any time after initial filing of a
      Registration Statement, file any Prospectus, any amendment of or
      supplement to a Registration Statement or a Prospectus, or any document
      that is to be incorporated by reference into a Registration Statement or a
      Prospectus, of which the Initial Purchasers and their counsel (and, in the
      case of a Shelf Registration Statement, the Holders of Registrable
      Securities covered thereby and their counsel) shall not have previously
      been advised and furnished a copy or to which the Initial Purchasers or
      their counsel (and, in the case of a Shelf Registration Statement, such
      Holders or their counsel) shall reasonably object on a timely basis,
      except for any Registration Statement or amendment thereto or related
      Prospectus or supplement thereto (a copy of which has been previously
      furnished as provided in the preceding sentence) which counsel to the
      Company has advised the Company in writing (with a copy to the objecting
      Initial Purchasers or Holders, as the case may be) is required to be filed
      in order to comply with applicable law;

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

            (l) cause the Indenture to be qualified under the Trust Indenture
      Act in connection with the registration of the Exchange Securities or
      Registrable Securi-

                                       13
<PAGE>

      ties, as the case may be; 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 Trust Indenture
      Act; and execute, and use their reasonable 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;

            (m) in the case of a Shelf Registration, make available for
      inspection by a representative of the Holders of the Registrable
      Securities covered thereby (an "Inspector"), any underwriter participating
      in any disposition pursuant to such Shelf Registration Statement, and
      attorneys and accountants designated by the Holders, at reasonable times
      and in a reasonable manner, all pertinent financial and other records,
      documents and properties of the Company and the Guarantors, and cause the
      respective officers, directors and employees of the Company and the
      Guarantors to supply all information reasonably requested by any such
      Inspector, Underwriter, attorney or accountant in connection with a Shelf
      Registration Statement; provided that each such representative,
      Underwriter, attorney or accountant shall agree in writing that it will
      keep such information confidential and that it will not disclose any of
      the information that the Company determines, in good faith, to be
      confidential and notifies them is confidential unless (i) the disclosure
      of such information is required by law (including as necessary to avoid or
      correct a material misstatement or material omission in such Registration
      Statement or Prospectus), (ii) the release of such information is ordered
      pursuant to a subpoena or other order from a court of competent
      jurisdiction, or (iii) such information has been made generally available
      to the public other than by any of such persons or their affiliates;
      provided, however, that each such representative, underwriter, attorney or
      accountant shall use commercially reasonable efforts to give prior notice
      as soon as practicable to the Company of the potential disclosure of any
      information by such person pursuant to clause (i) or (ii) of this sentence
      in order to permit the Company to obtain a protective order (or waive the
      provisions of this paragraph (m));

            (n) if reasonably requested by any Holder of Registrable Securities
      covered by a Registration Statement, promptly incorporate in a Prospectus
      supplement or post-effective amendment such information with respect to
      such Holder as such Holder reasonably requests to be included therein and
      make all required filings of such Prospectus supplement or such
      post-effective amendment as soon as the Company has received notification
      of the matters to be incorporated in such filing; and

                                       14
<PAGE>

            (o) in the case of a Shelf Registration, enter into such customary
      agreements and take all such other actions in connection therewith
      (including those requested by the Holders of a majority in principal
      amount of the Registrable Securities being sold) in order to expedite or
      facilitate the disposition of such Registrable Securities including, but
      not limited to, an Underwritten Offering and in such connection, (i) to
      the extent possible, make such representations and warranties to the
      Holders and any Underwriters of such Registrable Securities with respect
      to the business of the Company and its subsidiaries, the Registration
      Statement, Prospectus and documents incorporated by reference or deemed
      incorporated by reference, if any, in each case, in form, substance and
      scope as are customarily made by issuers to underwriters in underwritten
      offerings and confirm the same if and when requested, (ii) obtain opinions
      of counsel to the Company and the Guarantors (which counsel and opinions,
      in form, scope and substance, shall be reasonably satisfactory to the
      Holders and such Underwriters and their respective counsel) addressed to
      each selling Holder and Underwriter of Registrable Securities, covering
      the matters customarily covered in opinions requested in underwritten
      offerings, (iii) obtain "comfort" letters from the independent certified
      public accountants of the Company and the Guarantors (and, if necessary,
      any other certified public accountant of any subsidiary of the Company or
      any Guarantor, or of any business acquired by the Company or any Guarantor
      for which financial statements and financial data are or are required to
      be included in the Registration Statement) addressed to each selling
      Holder and Underwriter of Registrable Securities, such letters to be in
      customary form and covering matters of the type customarily covered in
      "comfort" letters in connection with underwritten offerings and (iv)
      deliver such documents and certificates as may be reasonably requested by
      the Holders of a majority in principal amount of the Registrable
      Securities being sold thereunder or the Underwriters, and which are
      customarily delivered in underwritten offerings, to evidence the continued
      validity of the representations and warranties of the Company and the
      Guarantors made pursuant to clause (i) above and to evidence compliance
      with any customary conditions contained in an underwriting agreement.

      In the case of a Shelf Registration Statement, each Holder of Registrable
Securities agrees that, upon receipt of any notice from the Company and the
Guarantors of the happening of any event of the kind described in Section
3(e)(iii) or 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(i) hereof and, if so directed by the Company and the
Guarantors, such Holder will deliver to the Company and the Guarantors all
copies in its possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities that is
current at the time of receipt of such notice.

                                       15
<PAGE>

      If the Company and the Guarantors shall give any such notice to suspend
the disposition of Registrable Securities pursuant to a Registration Statement,
the Company and the Guarantors shall extend the period during which the
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. The Company and the Guarantors may give any such notice only
twice during any 365-day period and any such suspensions shall not exceed 30
days for each suspension and there shall not be more than two suspensions in
effect during any 365-day period.

      The Holders of Registrable Securities covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Securities in an
Underwritten Offering. In any such Underwritten Offering, the investment banker
or investment bankers and manager or managers (the "Underwriters") that will
administer the offering will be selected by the Majority Holders of the
Registrable Securities included in such offering.

            4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff
of the SEC has taken the position that any broker-dealer that receives Exchange
Securities for its own account in the Exchange Offer in exchange for Securities
that were acquired by a Participating Broker-Dealer may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Securities.

      The Company and the Guarantors understand that it is the Staff,s position
that if the Prospectus contained in the Exchange Offer Registration Statement
includes a plan of distribution containing a statement to the above effect and
the means by which Participating Broker-Dealers may resell the Exchange
Securities, without naming the Participating Broker-Dealers or specifying the
amount of Exchange Securities owned by them, such Prospectus may be delivered by
Participating Broker-Dealers to satisfy their prospectus delivery obligation
under the Securities Act in connection with resales of Exchange Securities for
their own accounts, so long as the Prospectus otherwise meets the requirements
of the Securities Act.

            (b) In light of the above, and notwithstanding the other provisions
of this Agreement, the Company and the Guarantors agree to amend or supplement
the Prospectus contained in the Exchange Offer Registration Statement, as would
otherwise be contemplated by Section 3(i), for a period of up to 180 days after
the last Exchange Date (as such period may be extended pursuant to the
penultimate paragraph of Section 3 of this Agreement), if reasonably requested
by the initial Purchasers or by one or more Participating Broker-Dealers, in
order to expedite or facilitate the disposition of any Exchange Securities by
Participating Broker-Dealers consistent with the po-

                                       16
<PAGE>

sitions of the Staff recited in Section 4(a) above. The Company and the
Guarantors further agree that Participating Broker-Dealers shall be authorized
to deliver such Prospectus during such period in connection with the resales
contemplated by this Section 4.

            (c) The Initial Purchasers shall have no liability to the Company,
any Guarantor or any Holder with respect to any request that they may make
pursuant to Section 4(b) above.

            5. Indemnification and Contribution. (a) The Company and each
Guarantor, jointly and severally, agree to indemnify and hold harmless each
Initial Purchaser and each Holder, their respective affiliates, directors and
officers and each person, if any, who controls any Initial Purchaser or any
Holder within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, from and against any and all losses, claims, damages and
liabilities (including, without limitation, reasonable legal fees and other
expenses incurred in connection with any suit, action or proceeding or any claim
asserted, as such fees and expenses are incurred), joint or several, that arise
out of, or are based upon, any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement or any Prospectus or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, except
(i) insofar as such losses, claims, damages or liabilities arise out of, or are
based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information relating
to any Initial Purchaser or any Holder furnished to the Company in writing by
any Initial Purchaser or any selling Holder expressly for use therein or (ii)
that with respect to any such untrue statement in or omission from or alleged
untrue statement in or omission from any preliminary Prospectus, the indemnity
provided in this Section 5(a) shall not inure to the benefit of any Holder from
whom the person asserting any such loss, claim, damage or liability received
Registrable Securities or Exchange Securities to the extent that such loss,
claim, damage or liability results from the fact that (A) such Holder was
required under the Securities Act to deliver a copy of the final Prospectus to
such person at or prior to the written confirmation of the sale of Registrable
Securities or Exchange Securities to such person, (B) a copy of the final
Prospectus was not so sent or given to such person at or prior to the written
confirmation of the sale of such Registrable Securities or Exchange Securities
to such person and (C) such untrue statement in or omission from or alleged
untrue statement in or omission from the preliminary Prospectus was corrected in
the final Prospectus unless, in either case, such failure to deliver the final
Prospectus was a result of non-compliance by the Company or any of the
Guarantors with Section 2(b) or 3 hereof. In connection with any Underwritten
Offering permitted by Section 3, the Company and the Guarantors, jointly and
severally, will also indemnify the Underwriters, if any, selling brokers,
dealers and similar securities industry professionals participating in the
distribution, their respective af-

                                       17
<PAGE>

filiates and each Person who controls such Persons (within the meaning of the
Securities Act and the Exchange Act) to the same extent as provided above with
respect to the indemnification of the Holders, if requested in connection with
any Registration Statement.

            (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Guarantors, the Initial Purchasers and the other
selling Holders, their respective affiliates, the directors of the Company and
the Guarantors, each officer of the Company and the Guarantors who signed the
Registration Statement and each Person, if any, who controls the Company, the
Guarantors, any Initial Purchaser and any other selling Holder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the indemnity set forth in paragraph (a) above, but only with
respect to any losses, claims, damages or liabilities that arise out of, or are
based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information re lating
to such Holder furnished to the Company in writing by such Holder expressly for
use in any Registration Statement or any Prospectus.

            (c) If any suit, action, proceeding (including any governmental or
regu latory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnification may be sought pursuant to either
paragraph (a) or (b) above, such Person (the "Indemnified Person") shall
promptly notify the Person against whom such indemnification may be sought (the
"Indemnifying Person") in writing; provided that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under this Section 5 except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and
provided, further, that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have to an Indemnified Person
otherwise than under this Section 5. If any such proceeding shall be brought or
asserted against an Indemnified Person and it shall have notified the
Indemnifying Person thereof, the Indemnifying Person shall retain counsel
reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others entitled to indemnification pursuant to this Section 5
that the Indemnifying Person may designate in such proceeding and shall pay the
reasonable fees and expenses of such counsel related to such proceeding, as
incurred. In any such proceeding, any Indemnified Person shall have the right to
retain its own counsel, but the reasonable fees and expenses of such counsel
shall be at the expense of such Indemnified Person unless (i) the Indemnifying
Person and the Indemnified Person shall have mutually agreed to the contrary;
(ii) the Indemnifying Person has failed within a reasonable time to retain
counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified
Person shall have reasonably concluded that there may be legal defenses
available to it that are different from or in addition to those available to the
Indemnifying Person; or (iv) the named parties in any such proceeding (including
any im-

                                       18
<PAGE>

pleaded parties) include both the Indemnifying Person and the Indemnified Person
and representation of both parties by the same counsel would be inappropriate
due to actual or potential differing interests between them. It is understood
and agreed that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
reasonable fees and expenses of more than one separate firm (in addition to any
local counsel) for all Indemnified Persons, and that all such fees and expenses
shall be reimbursed as they are incurred. Any such separate firm (x) for any
Initial Purchaser, its affiliates, directors and officers and any control
Persons of such Initial Purchaser shall be designated in writing by Banc of
America Securities LLC, (y) for any other Holders, their affiliates, directors
and officers and any control Persons of such Holders shall be designated in
writing by the Majority Holders and (z) in all other cases shall be designated
in writing by the Company. The Indemnifying Person shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there be a final judgment for the plaintiff, the
Indemnifying Person agrees to indemnify each Indemnified Person from and against
any loss or liability by reason of such settlement or judgment to the extent
provided herein and therein. Notwithstanding the foregoing sentence, if at any
time an Indemnified Person shall have requested that an Indemnifying Person
reimburse the Indemnified Person for reasonable fees and expenses of counsel as
contemplated by this paragraph, the Indemnifying Person shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 60 days after receipt by the Indemnifying
Person of such request and (ii) the Indemnifying Person shall not have
reimbursed the Indemnified Person in accordance with such request prior to the
date of such settlement. No Indemnifying Person shall, without the written
consent of the Indemnified Person, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnification could have been sought hereunder by such
Indemnified Person, unless such settlement (A) includes an unconditional release
of such Indemnified Person, in form and substance reasonably satisfactory to
such Indemnified Person, from all liability on claims that are the subject
matter of such proceeding and (B) does not include any statement as to or any
admission of fault, culpability or a failure to act by or on behalf of any
Indemnified Person.

            (d) If the indemnification provided for in paragraphs (a) and (b)
above is unavailable to an Indemnified Person or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Guarantors from the offering of the
Securities and the Exchange Securities, on the one hand, and by the Holders from
receiving Securities or Exchange Securities registered under the Securities Act,
on the other

                                       19
<PAGE>

hand, 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) but also the relative fault of the
Company and the Guarantors on the one hand and the Holders on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantors on the one
hand and the Holders on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Guarantors or by the Holders and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

            (e) The Company, the Guarantors and the Holders agree that it would
not be just and equitable if contribution pursuant to this Section 5 were
determined by pro rata allocation (even if the Holders were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in paragraph (d) above. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any reasonable
legal or other expenses incurred by such Indemnified Person in connection with
any such action or claim. Notwithstanding the provisions of this Section 5, in
no event shall a Holder be required to contribute any amount in excess of the
amount by which the total price at which the Securities or Exchange Securities
sold by such Holder exceeds the amount of any damages that such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11 (f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

            (f) The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies that may otherwise be available to
any Indemnified Person at law or in equity.

            (g) The indemnity and contribution provisions contained in this
Section 5 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of the Initial Purchasers or any Holder, their respective affiliates or any
Person controlling any Initial Purchaser or any Holder, or by or on behalf of
the Company or the Guarantors, their respective affiliates or the officers or
directors of or any Person controlling the Company or the Guarantors, (iii)
acceptance of any of the Exchange Securities and (iv) any sale of Registrable
Securities pursuant to a Shelf Registration Statement.

            6. General.

            (a) No Inconsistent Agreements. The Company and the Guarantors,
jointly and severally, represent, warrant and agree that (i) the rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of any other outstanding
securities issued or guaranteed by the Company or any Guarantor under any other
agreement and (ii) neither the Company nor any Guarantor has entered into, or
on or after the date of this Agreement will enter into, any agreement that is
inconsistent with the rights granted to the Holders of Registrable Securities in
this Agreement or otherwise conflicts with the provisions hereof.

            (b) Amendments and Waivers. The provisions of this Agreement, in-
cluding the provisions of this sentence, may not be amended, modified or supple-

Guarantors with respect to any failure by a Holder to comply with, or any breach
by any Holder of, any of the obligations of such Holder under this Agreement.

            (e) Purchases and Sales of Securities. The Company and the Guaran-
tors shall not, and shall use their reasonable best efforts to cause their

            (f) Third Party Beneficiaries. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, 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 or the rights of
other Holders hereunder.

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

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

in accordance with the laws of the State of New York.

            (j) Miscellaneous. This Agreement contains the entire agreement

covenant or restriction contained in this Agreement is held by a court of
competent jurisdiction to be inva-

                                       22

lid, void or unenforceable or against public policy, the remainder of the terms,
provisions, covenants and restrictions contained herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated. The
Company, the Guarantors and the Initial Purchasers shall endeavor in good faith
negotiations to replace the invalid, void or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to that of
the invalid, void or unenforceable provisions.
