        2.    Registration Under the 1933 Act.    


        (a)   To
the extent not prohibited by any applicable law or applicable interpretation of the Staff of the SEC, the Issuers shall use their commercially reasonable efforts to
cause to be filed an Exchange Offer
Registration Statement covering the offer by the Issuers to the Holders to exchange all of the Registrable Securities for Exchange Securities and to have such Registration Statement remain effective
until the closing of the Exchange Offer. The Issuers shall commence the Exchange Offer promptly after the Exchange Offer Registration Statement has been declared effective by the SEC and use their
commercially reasonable efforts to have the Exchange Offer consummated not later than 60 days after such effective date. 


        The
Issuers shall commence the Exchange Offer by mailing the related exchange offer Prospectus and accompanying documents to each Holder stating, in addition to such other disclosures as
are required by applicable law: 



          (i)  that
the Exchange Offer is being made pursuant to this Registration Rights Agreement and that all Registrable Securities validly tendered 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 Registration Rights
Agreement; 


        (iv)  that
Holders electing to have a Registrable Security exchanged pursuant to the Exchange Offer will be required to surrender such Registrable Security, together with the
enclosed letters of transmittal, to the institution and at the address (located in the Borough of Manhattan, The City of New York) specified in the notice prior to the close of business on the last
Exchange Date; and 


         (v)  that
Holders will be entitled to withdraw their 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 exchange and a statement that such Holder is withdrawing his election to have such Securities exchanged. 




        As
soon as practicable after the last Exchange Date, the Issuers shall: 



          (i)  accept
for exchange Registrable Securities or portions thereof tendered and not validly 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 Issuers and issue, and
cause the Trustee to promptly authenticate and mail to each Holder, an Exchange Security equal in principal amount to the principal amount of the Registrable Securities surrendered by such Holder. 




The
Issuers shall use their commercially reasonable efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the 1933 Act, the 1934 Act and other
applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any material conditions, other than that the Exchange Offer does not violate
applicable law or any applicable interpretation of the Staff of the SEC. The Issuers shall inform the Placement Agents of the names and addresses of the Holders to whom the Exchange Offer is made, and
the Placement Agents shall have the right, subject to applicable law, to contact such Holders and otherwise facilitate the tender of Registrable Securities in the Exchange Offer. 



4





 

        (b)   In
the event that (i) the Issuers determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be
consummated as soon as practicable after the last Exchange Date because it would violate applicable law or the applicable interpretations of the Staff of the SEC, (ii) the Exchange Offer is not
for any other reason consummated by 210 days after the Closing Date or (iii) the Exchange Offer has been completed and in the opinion of counsel for the Placement Agents a Registration
Statement must be filed and a Prospectus must be delivered by the Placement Agents in connection with any offering or sale of Registrable Securities, the Issuers shall use their commercially
reasonable efforts to cause to be filed as soon as practicable after such determination, date or notice of such opinion of counsel is given to the Issuers, as the case may be, a Shelf Registration
Statement providing for the sale by the Holders of all of the Registrable Securities and to have such Shelf Registration Statement declared effective by the SEC. In the event the Issuers are required
to file a Shelf Registration Statement solely as a result of the matters referred to in clause (iii) of the preceding sentence, the Issuers shall use their 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 Placement Agents after
completion of the Exchange Offer. The Issuers agree to use their commercially reasonable efforts to keep the Shelf Registration Statement continuously effective until the expiration of the period
referred to in Rule 144(k) with respect to the Registrable Securities or such shorter period that will terminate when all of the Registrable Securities covered by the Shelf Registration
Statement have been sold pursuant to the Shelf Registration Statement. The Issuers further agree to supplement or amend the Shelf Registration Statement if required by the rules, regulations or
instructions applicable to the registration form used by the Issuers for such Shelf Registration Statement or by the 1933 Act or by any other rules and regulations thereunder for shelf registration or
if reasonably requested by a Holder with respect to information relating to such Holder, and to use their commercially reasonable efforts to cause any such amendment to become effective and such Shelf
Registration Statement to become usable as soon as thereafter practicable. The Issuers agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly
after its being used or filed with the SEC. 


        (c)   The
Issuers shall pay all Registration Expenses in connection with the registration pursuant to Section 2(a) and Section 2(b). 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. 


        (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; 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. In the event the Exchange Offer is not consummated and the Shelf Registration Statement is not declared effective as
set forth below, then, the interest rate on the Securities will be increased (the "Additional Interest") as follows: 



          (i)  if
(A) neither the Exchange Offer Registration Statement nor a Shelf Registration Statement has been filed with the SEC within 120 days after the Closing
Date or (B) the Issuers are required to file a Shelf Registration Statement pursuant to Section 2(b)(iii) hereof 




5





 


and
such Shelf Registration Statement is not filed on or prior to the Filing Date applicable thereto then, commencing on the day after either such 120th day in the case of
clause (A) or such Filing Date in the case of clause (B), Additional Interest shall accrue on the principal amount of the Registrable Securities at a rate of 0.25% per annum for the
first 90 days immediately following thereafter, and such Additional Interest rate shall increase by an additional 0.25% per annum at the beginning of each subsequent 90-day period;
or 


         (ii)  if
(A) neither the Exchange Offer Registration Statement nor a Shelf Registration Statement is declared effective by the SEC within 180 days after the
Closing Date or (B) the Issuers are required to file a Shelf Registration Statement pursuant to Section 2(b)(iii) hereof and such Shelf Registration Statement is not
declared effective by the SEC on or prior to the 60th day following the Filing Date applicable thereto then, commencing on the day after either such 180th day in the case
of clause (A) or 60th day following the Filing Date in the case of clause (B), Additional Interest shall accrue on the principal amount of the Registrable Securities at a
rate of 0.25% per annum for the first 90 days immediately following thereafter, and such Additional Interest rate shall increase by an additional 0.25% per annum at the beginning of each
subsequent 90-day period; or 


        (iii)  subject
to Sections 2(f) and 2(g), if (A) the Issuers have not exchanged Exchange Securities for all Securities validly tendered in accordance with the terms of
the Exchange Offer on or prior to the 210th day after the Closing Date or (B) if applicable, the Shelf Registration Statement has been declared effective and such Shelf
Registration Statement ceases to be effective at any time prior to the second
anniversary of the Closing Date (or, if earlier, the date when all Securities have been disposed of thereunder), then Additional Interest shall accrue on the principal amount of the Registrable
Securities at a rate of 0.25% per annum for the first 90 days commencing on (x) the 211th day after the Closing Date, in the case of (A) above, or (y) the day
such Shelf Registration Statement ceases to be effective in the case of (B) above, and such Additional Interest rate shall increase by an additional 0.25% per annum at the beginning of each
subsequent 90-day period; 




provided, however, that the Additional Interest rate on the Securities may not exceed in the aggregate
1.0% per annum; provided further, that the Issuers shall in no event be required to pay additional interest for more than one event in
clauses (i), (ii), or (iii) at any one time; provided further, however, that (1) upon the
filing of the Exchange Offer Registration Statement or a Shelf Registration Statement (in the case of clause (i) above), (2) upon the effectiveness of the Exchange Offer Registration or a Shelf
Registration Statement (in the case of clause (ii) above), or (3) upon the exchange of Exchange Securities for all Securities tendered (in the case of clause (iii)(A) above), or (4) upon
the effectiveness of the Shelf Registration Statement which had ceased to remain effective (in the case of clause (iii)(B) above), Additional Interest on the Securities as a result of such
clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. 



        (e)   Without
limiting the remedies available to the Placement Agents and the Holders, the Issuers acknowledge that any failure by the Issuers to comply with their obligations
under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Placement Agents 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 Placement Agents or any Holder may obtain such relief as may be required to specifically
enforce the Issuers' obligations under Section 2(a) and Section 2(b) hereof.

        3.    Registration Procedures.    


        In
connection with the obligations of the Issuers with respect to the Registration Statements pursuant to Section 2(a) and Section 2(b) hereof, the Issuers shall as
expeditiously as possible: 



        (a)   prepare
and file with the SEC a Registration Statement on the appropriate form under the 1933 Act, which form (x) shall be selected by the Issuers and
(y) shall, in the case of a Shelf Registration, be available for the sale of the Registrable Securities 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 their commercially reasonable 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 to keep such Registration
Statement effective for the applicable period and cause each Prospectus to be supplemented by any required prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424 under
the 1933 Act; to keep each Prospectus current during the period described under Section 4(3) and Rule 174 under the 1933 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, to counsel for the Placement Agents, to counsel for the 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 and such other documents as such Holder or Underwriter may reasonably request, in order to facilitate the public sale or other disposition of the Registrable Securities; and the Issuers
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
their best efforts to register or qualify the Registrable Securities under all applicable state securities or "blue sky" laws of such jurisdictions as any Holder of
Registrable Securities covered by a Registration Statement shall reasonably request in writing by the time the applicable Registration Statement is declared effective by the SEC, to cooperate with
such 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 which may be reasonably
necessary or advisable to enable such Holder to consummate the disposition in each such jurisdiction of such Registrable Securities owned by such Holder;  provided, however, that the Issuers shall not be required to (i) qualify as a foreign corporation
or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (ii) file any general consent to service of process or
(iii) subject itself to taxation in any such jurisdiction if it is not so subject; 


        (e)   in
the case of a Shelf Registration, notify each Holder of Registrable Securities, counsel for the Holders and counsel for the Placement Agents promptly and, if
requested by any such Holder or counsel, confirm such advice in writing (i) when a Registration Statement has become effective and when any post-effective amendment thereto has been
filed and becomes effective, (ii) of any request by the SEC or any state securities authority for amendments and supplements to a Registration Statement and Prospectus or for additional
information after the Registration Statement has become effective, (iii) of the issuance by the SEC or any state securities authority of any stop order suspending the effectiveness of a 




7





 





Registration
Statement or the initiation of any 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 Issuers contained in any underwriting agreement, securities sales agreement or other similar agreement, if any, relating to the
offering cease to be true and correct in all material respects or if the Issuers receive 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 which makes any statement
made in such Registration Statement or the related Prospectus untrue in any material respect or which requires the making of any changes in such Registration Statement or Prospectus in order to make
the statements therein not misleading and (vi) of any determination by the Issuers that a post-effective amendment to a Registration Statement would be appropriate; 



        (f)    make
every reasonable effort 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, without charge, at least one conformed copy of each Registration Statement and any
post-effective amendment thereto (without 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 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 in such denominations (consistent with the provisions of the
Indenture) and registered in such names as the selling Holders may reasonably request at least one business day prior to the closing of any sale of Registrable Securities; 


        (i)    in
the case of a Shelf Registration, upon the occurrence of any event contemplated by Section 3(e)(v) hereof, use their best 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 the 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 light of the circumstances under which they were made, not misleading. The Issuers agree to notify the Holders to suspend use of the Prospectus as promptly
as practicable after the occurrence of such an event, and the Holders hereby agree to suspend use of the Prospectus until the Issuers have amended or supplemented the Prospectus to correct such
misstatement or omission; 




8













  




        (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 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
Placement Agents and their counsel (and, in the case of a Shelf Registration Statement, the Holders and their counsel) and make such of the representatives of the Issuers as shall be reasonably
requested by the Placement Agents or their counsel (and, in the case of a Shelf Registration Statement, the Holders or their counsel) available for discussion of such document, and shall not at any
time file or make any amendment to the Registration Statement, any Prospectus or any amendment of or supplement to a Registration Statement or a Prospectus or any document which is to be incorporated
by reference into a Registration Statement or a Prospectus, of which the Placement Agents and their counsel (and, in the case of a Shelf Registration Statement, the Holders and their counsel) shall
not have previously been advised and furnished a copy or to which the Placement Agents or their counsel (and, in the case of a Shelf Registration Statement, the Holders or their counsel) shall
reasonably object within five days after receipt thereof. 


        (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 of 1939, as amended (the "TIA"), in connection with the registration of the Exchange Securities or
Registrable Securities, 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 TIA and execute, and use their 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, 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 financial and other records,
pertinent documents and properties of the Issuers and subsidiaries of the Issuers, and cause the respective officers, directors and employees of the Issuers to supply all information reasonably
requested by any such representative, Underwriter, attorney or accountant in connection with a Shelf Registration Statement; provided that any such representative, underwriter or other recipient shall
agree in writing that any information designated as confidential by the Company shall be kept confidential by such recipient except to the extent reasonably necessary in connection with an offering; 


        (n)   in

on which similar securities issued by the Issuers are then listed if requested by the Majority Holders, to the extent such Registrable Securities satisfy applicable listing requirements; 



        (o)   if
reasonably requested by any Holder of Registrable Securities covered by a Registration Statement, (i) 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 (ii) make all required filings of such Prospectus
supplement or such post-effective amendment as soon as the Issuers have received notification of the matters to be incorporated in such filing; and 




9





 





        (p)   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 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 Issuers and their 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 Issuers
(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 "cold comfort" letters from the independent
certified public accountants of the Issuers (and, if necessary, any other certified public accountant of any subsidiary of the Issuers, or of any business acquired by the Issuers 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 "cold 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 or the Underwriters, and which are customarily delivered in underwritten offerings, to
evidence the continued validity of the representations and warranties of the Issuers 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, the Issuers may require each Holder of Registrable Securities to furnish to the Issuers such information regarding the Holder and the
proposed distribution by such Holder of such Registrable Securities as the Issuers may from time to time reasonably request in writing. 


        In
the case of a Shelf Registration Statement, each Holder agrees that, upon receipt of any notice from the Issuers of the happening of any event 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(i) hereof, and, if so directed by the Issuers, such Holder will deliver to the Issuers (at their expense) all copies in its
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 Issuers
shall give any such notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the Issuers 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 Issuers may give any such notice only twice during any 365 day period and any such
suspensions may not exceed 30 days for each suspension and there may 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 



10





 




"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 such broker-dealer as a result of market-making or other trading activities (a "Participating Broker-Dealer"), may be deemed to be an "underwriter" within the meaning of the 1933
Act and must deliver a prospectus meeting the requirements of the 1933 Act in connection with any resale of such Exchange Securities. 



        The
Issuers 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 1933 Act in connection with resales of
Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the 1933 Act. 



        (b)   In
light of the above, notwithstanding the other provisions of this Agreement, the Issuers agree that the provisions of this Agreement as they relate to a Shelf
Registration shall also apply to an Exchange Offer Registration to the extent, and with such reasonable modifications thereto as may be, reasonably requested by the Placement Agents or by one or more
Participating Broker-Dealers, in each case as provided in clause (ii) below, in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers
consistent with the positions of the Staff recited in Section 4(a) above; provided that: 



          (i)  the
Issuers shall not be required 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 exceeding 180 days after the last Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement)
and Participating Broker-Dealers shall not be authorized by the Issuers to deliver and shall not deliver such Prospectus after such period in connection with the resales contemplated by this
Section 4; and 


         (ii)  the
application of the Shelf Registration procedures set forth in Section 3 of this Agreement to an Exchange Offer Registration, to the extent not required by
the positions of the Staff of the SEC or the 1933 Act and the rules and regulations thereunder, will be in conformity with the reasonable request to the Issuers by the Placement Agents or with the
reasonable request in writing to the Issuers by one or more broker-dealers who certify to the Placement Agents and the Issuers in writing that they anticipate that they will be Participating
Broker-Dealers; and provided further that, in connection with such application of the Shelf Registration procedures set forth in Section 3 to an
Exchange Offer Registration, the Issuers shall be obligated (x) to deal only with one entity representing the Participating Broker-Dealers, which shall be Morgan Stanley & Co.
Incorporated unless it elects not to act as such representative, (y) to pay the fees and expenses of only one counsel representing the Participating Broker-Dealers, which shall be counsel to
the Placement Agents unless such counsel elects not to so act and (z) to cause to be delivered only one, if any, "cold comfort" letter with respect to the Prospectus in the form existing on the
last Exchange Date and with respect to each subsequent amendment or supplement, if any, effected during the period specified in clause (i) above. 




11





 





        (a)   The
Placement Agents shall have no liability to the Issuers or any Holder with respect to any request that it may make pursuant to Section 4(b) above. 




        5.    Indemnification and Contribution.    


        (a)   Each
of the Issuers, jointly and severally, agrees to indemnify and hold harmless the Placement Agents, each Holder and each Person, if any, who controls any Placement
Agent or any Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under common control with, or is controlled by, any Placement Agent or
any Holder, from and against all losses,
claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by the Placement Agents, any Holder or any such controlling or affiliated Person in
connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any
amendment thereto) pursuant to which Exchange Securities or Registrable Securities were registered under the 1933 Act, including all documents incorporated therein by reference, or caused by any
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or caused by any untrue statement or alleged
untrue statement of a material fact contained in any Prospectus (as amended or supplemented if the Issuers shall have furnished any amendments or supplements thereto), or caused by any omission or
alleged omission to state therein a material fact necessary to make the statements therein in light of the circumstances under which they were made not misleading, except insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Placement Agents or any Holder
furnished to the Issuers in writing through Morgan Stanley & Co. Incorporated or any selling Holder expressly for use therein, provided that, the foregoing indemnity with respect to any
preliminary Prospectus shall not inure to the benefit of any Holder from whom the person asserting any such losses, claims, damages or liabilities purchased Notes, or any person controlling such
Holder, if a copy of the final Prospectus (as then amended or supplemented if the Company and the Guarantors shall have furnished any amendments or supplements thereto) was not sent or given by or on
behalf of such Holder to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Notes to such person, and if the final Prospectus (as so
amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability. In connection with any Underwritten Offering permitted by Section 3, the Issuers will
also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their officers and directors and each Person who
controls such Persons (within the meaning of the 1933 Act and the 1934 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 Issuers, the Placement Agents and the other selling Holders, and each of their
respective directors, officers who sign the Registration Statement and each Person, if any, who controls the Issuers, any Placement Agent and any other selling Holder within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Issuers to the Placement Agents and the Holders, but only with reference
to information relating to such Holder furnished to the Issuers in writing by such Holder expressly for use in any Registration Statement (or any amendment thereto) or any Prospectus (or any amendment
or supplement thereto). 


        (c)   In
case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to either
paragraph (a) or paragraph (b) above, such Person (the "indemnified party") shall promptly notify the Person 



12





 




against
whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party
unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (a) the fees and
expenses of more than one separate firm (in addition to any local counsel) for the Placement Agents and all Persons, if any, who control any Placement Agent within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Issuers, their
directors, their officers who sign the Registration Statement and each Person, if any, who controls the Issuers within the meaning of either such Section and (c) the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Holders and all Persons, if any, who control any Holders within the meaning of either such Section, and that all such fees and
expenses shall be reimbursed as they are incurred. In such case involving the Placement Agents and Persons who control the Placement Agents, such firm shall be designated in writing by Morgan
Stanley & Co. Incorporated. In such case involving the Holders and such Persons who control Holders, such firm shall be designated in writing by the Majority Holders. In all other cases, such
firm shall be designated by the Issuers. The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing 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 as
contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if
(i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed
the indemnified party for such fees and expenses of counsel in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding in respect of which such indemnified party is or could have been a party and indemnity could have been sought hereunder
by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. 


        (d)   If
the indemnification provided for in paragraph (a) or paragraph (b) of this Section 5 is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid
or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties
on the one hand and of the indemnified party or parties on the other hand 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 Issuers and the Holders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the 



13





 




omission
or alleged omission to state a material fact relates to information supplied by the Issuers or by the Holders and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Holders' respective obligations to contribute pursuant to this Section 5(d) are several in proportion to the respective
principal amount of Registrable Securities of such Holder that were registered pursuant to a Registration Statement. 



        (e)   The
Issuers and each Holder agree that it would not be just or equitable if contribution pursuant to this Section 5 were determined by pro
rata allocation 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 party 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 legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this
Section 5, no Holder shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which Registrable Securities were 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 1933 Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The remedies
provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 



        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 Placement Agents, any Holder or any Person controlling any Placement Agent or any Holder, or by or on behalf of the Issuers, their
officers or directors or any Person controlling the Issuers, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf
Registration Statement. 


        6.    Miscellaneous.    



        (a)    No Inconsistent Agreements.    None of the Issuers has entered into, and on or after the date of this Agreement
will not enter into, any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The
rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Issuers' other issued and outstanding securities under
any such agreements. 


        (b)    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 Issuers have 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 consent;  provided, however, that no amendment, modification, supplement, waiver or consent to any departure from
the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder. 


        (c)    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 (i) if to a Holder, at the most current address given by such Holder
to the Issuers by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to the Placement Agents, the address set forth 



14





 




in
the Placement Agreement; and (ii) if to the Issuers, initially at the Company's address set forth in the Placement Agreement and thereafter at such other address, notice of which is given in
accordance with the provisions of this Section 6(c). 


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


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



        (d)    Successors 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 Placement 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 and such Person shall be entitled to receive the benefits hereof. The Placement Agents (in their capacity as Placement Agents) shall have no liability or obligation to the
Issuers 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.    Until the earlier of (1) two years after the Closing Date and
(2) the consummation of the Exchange Offer, the Issuers shall not, and shall use their best efforts to cause their affiliates (as defined in Rule 405 under the 1933 Act) not to, purchase
and then resell or otherwise transfer any Securities. 


        (f)    Third Party Beneficiary.    The Holders shall be third party beneficiaries to the agreements made hereunder
between the Issuers, on the one hand, and the Placement Agents, 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 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 and shall not limit or
otherwise affect the meaning hereof. 


        (i)    Governing Law.    This Agreement shall be governed by the laws of the State of New York. 


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