Securities Act, as soon as practicable, but no later than 60 days after the
Closing, a registration statement relating to an offer to exchange (such
registration statement, the "Exchange Registration Statement," and such offer,

Trust Indenture Act), except that they have been registered pursuant to an
effective registration statement under the Securities Act and do not contain
provisions for the additional interest contemplated in Section 2(c) below (such

Registration Statement to become effective under the Securities Act as soon as

will be registered under the Securities Act on the appropriate form and will
comply with all applicable tender offer rules and regulations under the Exchange
Act. The Company and the Guarantors further agree to use their respective best
efforts to commence and complete the Exchange Offer promptly, but no later than
45 days after such registration statement has become effective, hold the
Exchange Offer open for at least 30 days and issue Exchange Notes for all
Registrable Notes that have been properly tendered and not withdrawn on or prior
to the expiration of the Exchange Offer. The Exchange Offer will be deemed to
have been "completed" only if the debt securities received by holders other than
Restricted Holders in the Exchange Offer for Registrable Notes are, upon
receipt, transferable by each such holder without need for further compliance
with Section 5 of 


                                        4
   5

the Securities Act and the Exchange Act (except for the requirement to deliver a
prospectus included in the Exchange Registration Statement applicable to resales
by any broker-dealer of Exchange Securities received by such broker-dealer
pursuant to an Exchange Offer in exchange for Registrable Notes other than those
acquired by the broker-dealer directly from the Company), and without material
restrictions under the blue sky or securities laws of a substantial majority of
the States of the United States of America. The Exchange Offer shall be deemed
to have been completed upon the earlier to occur of (i) the Company having
exchanged the Exchange Notes for all outstanding Registrable Notes pursuant to
the Exchange Offer and (ii) the Company having exchanged, pursuant to the
Exchange Offer, Exchange Notes for all Registrable Notes that have been properly
tendered and not withdrawn before the expiration of the Exchange Offer, which
shall be on a date that is at least 30 days following the commencement of the
Exchange Offer. The Company and the Guarantors agree (x) to include in the
Exchange Registration Statement a prospectus for use in connection with any
resales of Exchange Notes by a broker-dealer, other than resales of Exchange
Notes received by a broker-dealer pursuant to an Exchange Offer in exchange for
Registrable Notes acquired by the broker-dealer directly from the Company, and
(y) to keep such Exchange Registration Statement effective for a period (the
"Resale Period") beginning when Exchange Notes are first issued in the Exchange
Offer and ending upon the earlier of the expiration of the 90th day after the
Exchange Offer has been completed or such time as such broker-dealers no longer
own any Registrable Notes. With respect to such Exchange Registration Statement,
each broker-dealer that holds Exchange Notes received in an Exchange Offer in
exchange for Registrable Notes not acquired by it directly from the Company
shall have the benefit of the rights of indemnification and contribution set
forth in Sections 6 hereof.

      (b) the Exchange Offer is completed existing Commission interpretations
are changed such that the Initial Notes received by holders other than
Restricted Holders in the Exchange Offer for Registrable Notes are not or would
not be, upon receipt, transferable by each such holder without need for further
compliance with Section 5 of the Securities Act (except for the requirement to
deliver a prospectus included in the Exchange Registration Statement applicable
to resales by broker-dealers of Exchange Securities received by such
broker-dealer pursuant to an Exchange Offer in exchange for Registrable Notes
other than those acquired by the broker-dealer directly from the Company), in
lieu of conducting the Exchange Offer contemplated by Section 2(a) the Company
and the Guarantors shall file under the Securities Act as soon as practicable,
but no later than the later of 30 days after the time such obligation to file
arises and 60 days after the Closing, a "shelf" registration statement providing
for the registration of, and the sale on a continuous or delayed basis by the
holders of, all of the Registrable Notes, pursuant to Rule 415 or any similar
rule that may be adopted by the Commission (such filing, the "Shelf
Registration" and such registration statement, the "Shelf Registration
Statement"). In addition, in the event that the Initial Purchasers shall not
have resold all of the Initial Notes initially purchased by them from the
Company 


                                        5
   6

pursuant to the Purchase Agreement prior to the consummation of the Exchange
Offer, the Company shall file under the Securities Act as soon as practicable a
Shelf Registration Statement. The Company and the Parent agree to use their
respective best efforts (i) to cause the Shelf Registration Statement to become
or be declared effective no later than 180 days after Closing and to keep such
Shelf Registration Statement continuously effective in order to permit the
prospectus forming a part thereof to be usable by holders for resales of
Registrable Notes for a period ending on the earlier of the second anniversary
of the Closing (or the first anniversary if the Shelf Registration is filed
because the Initial Purchasers have not resold all of the Initial Notes) or such
time as there are no longer any Registrable Notes outstanding, provided,
however, that no holder shall be entitled to be named as a selling
securityholder in the Shelf Registration Statement or to use the prospectus
forming a part thereof for resales of Registrable Notes unless such holder is an
Electing Holder, and (ii) after the Effective Time of the Shelf Registration
Statement, promptly upon the request of any holder of Registrable Notes that is
not then an Electing Holder, to take any action reasonably necessary to enable
such holder to use the prospectus forming a part thereof for resales of
Registrable Notes, including, without limitation, any action necessary to
identify such holder as a selling securityholder in the Shelf Registration
Statement, provided, however, that nothing in this clause (ii) shall relieve any
such holder of the obligation to return a completed and signed Notice and
Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The
Company further agrees to supplement or make amendments to the Shelf
Registration Statement, as and when required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or rules and regulations
thereunder for shelf registration, and the Company agrees to furnish to each
Electing Holder copies of any such supplement or amendment prior to its being
used or promptly following its filing with the Commission.

      (c) In the event that (i) the Company has not filed the Exchange
Registration Statement on or prior to the 60th day after the Closing, or (ii)
such Exchange Registration Statement has not become effective or been declared
effective by the Commission on or before the 150th day after the Closing, or
(iii) the Exchange Offer is not consummated or a Shelf Registration Statement is
not declared effective on or prior to the 180th day after the Closing, or (iv)
any Exchange Registration Statement or Shelf Registration Statement required by
Section 2(a) or 2(b) hereof is filed and declared effective but shall thereafter
either be withdrawn by the Company or shall become subject to an effective stop
order issued pursuant to Section 8(d) of the Securities Act suspending the
effectiveness of such registration statement (except as specifically permitted
herein) without being succeeded immediately by an additional registration
statement filed and declared effective (each such event referred to in clauses
(i) through (iv), a "Registration Default", then, as liquidated damages for each
such Registration Default, subject to the provisions of Section 9(b), the
interest rate borne by the Registrable Notes shall be increased by 0.25% per
annum following such 60-day period in the case of clause (i) 


                                        6
   7

above, following such 150-day period in the case of clause (ii) above, following
such 180-day period in the case of clause (iii) above and following the date on
which such Exchange Offer Registration Statement or the Shelf Registration
Statement, as the case may be, ceases to become effective in the case of clause
(iv) above. The amount of such additional interest will increase by an
additional 0.25% for each subsequent 90-day period until such Registration
Default has been cured; provided that the aggregate amount of such increase in
the original interest rate will in no event exceed 1.50% per annum. Upon (w) the
filing of the Exchange Offer Registration Statement after the 60-day period
described in clause (i) above, (x) the effectiveness of the Exchange Offer
Registration Statement after the 150-day period described in clause (ii) above,
(y) the consummation of the Exchange Offer or the effectiveness of the Shelf
Registration Statement, as the case may be, after the 180-day period described
in clause (iii) above or (z) the effectiveness of a succeeding registration
statement after the date in clause (iv) above, the interest rate borne by the
Registrable Notes from the date of filing, effectiveness or consummation, as the
case may be, will be reduced to the original interest rate.

      (d) The Company shall take all reasonable actions necessary or advisable
to be taken by it to ensure that the transactions contemplated herein are
effected as so contemplated.

      (e) Any reference herein to a registration statement as of any time shall
be deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time and any reference herein to any
post-effective amendment to a registration statement as of any time shall be
deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time.

      3. Registration Procedures. If the Company and the Guarantors file a
registration statement pursuant to Section 2(a) or Section 2(b), the following
provisions shall apply:

      (a) At or before the Effective Time of the Exchange Offer or the Shelf
Registration, as the case may be, the Company and the Guarantors shall qualify
the Indenture under the Trust Indenture Act.

      (b) In the event that such qualification would require the appointment of
a new trustee under the Indenture, the Company shall appoint a new trustee
thereunder pursuant to the applicable provisions of the Indenture.

      (c) In connection with the Company's and the Guarantors' obligations with
respect to the registration of Exchange Securities as contemplated by Section

      permit the Exchange Offer and resales of Exchange Notes by broker-dealers
      during the Resale Period to be effected as contemplated by Section 2(a),
      and use their respective best efforts to cause such Exchange Registration
      Statement to become effective as soon as practicable thereafter, but no

      Registration Statement or any post-effective amendment thereto at the
      earliest practicable date;

            (vi) use their respective reasonable best efforts to (A) register or

      member of an underwriting syndicate or selling group or "assist in the
      distribution" (within the meaning of the Rules of Fair Practice and the
      By-Laws of the National Association of Securities Dealers, Inc. ("NASD")
      or any successor thereto, as amended from time to time) thereof, whether
      as a holder of such Registrable Notes or as an underwriter, a placement or
      sales agent or a broker or dealer in respect thereof, or otherwise, assist
      such broker-dealer in complying with the requirements of such Rules and
      By-Laws, including by (A) if such Rules or By-Laws shall so require,
      engaging a "qualified independent underwriter" (as defined in such
      Schedule (or any successor thereto)) to participate in the preparation of
      the Shelf Registration Statement relating to such Registrable Notes, to
      exercise usual standards of due diligence in respect thereto and, if any
      portion of the offering contemplated by such Shelf Registration Statement
      is an underwritten offering or is made through a placement or sales agent,
      to recommend the yield of such Registrable Notes, (B) indemnifying any
      such qualified independent underwriter to the extent of the
      indemnification of underwriters provided in Section 6 hereof (or to such

      providing such information to such broker-dealer as may be required in
      order for such broker-dealer to comply with the requirements of the Rules

      Commission, and make generally available to its securityholders as soon as
      practicable but in any event not later than eighteen months after the
      effective date of such Shelf Registration Statement, an earning statement
      of the Company and its subsidiaries complying with Section 11(a) of the
      Securities Act (including, at the option of the Company, Rule 158
      thereunder).

      (e) In the event that the Company and the Parent would be required,
pursuant to Section 3(d)(viii)(F) above, to notify the Electing Holders, the
placement or sales agent, if any, therefor and the managing underwriters, if
any, thereof, the Company shall without delay prepare and furnish to each of the
Electing Holders, to each placement or sales agent, if any, and to each such
underwriter, if any, a reasonable number of copies of a prospectus supplemented
or amended so that, as thereafter delivered to purchasers of Registrable Notes,
such prospectus shall conform in all material respects to the applicable
requirements of the Securities Act and the Trust Indenture Act and the rules and
regulations of the Commission thereunder and shall not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or 


                                       16
   17

necessary to make the statements therein not misleading in light of the
circumstances then existing. Each Electing Holder agrees that upon receipt of
any notice from the Company pursuant to Section 3(d)(viii)(F) hereof, such
Electing Holder shall forthwith discontinue the disposition of Registrable Notes
pursuant to the Shelf Registration Statement applicable to such Registrable
Notes until such Electing Holder shall have received copies of such amended or
supplemented prospectus, and if so directed by the Company, such Electing Holder
shall deliver to the Company (at the Company's expense) all copies, other than
permanent file copies, then in such Electing Holder's possession of the
prospectus covering such Registrable Notes at the time of receipt of such
notice.

      (f) In the event of a Shelf Registration, in addition to the information
required to be provided by each Electing Holder in its Notice and Questionnaire,
the Company may require such Electing Holder to furnish to the Company such
additional information regarding such Electing Holder and such Electing Holder's
intended method of distribution of Registrable Notes as may be required in order
to comply with the Securities Act. Each such Electing Holder agrees to notify
the Company as promptly as practicable of any inaccuracy or change in
information previously furnished by such Electing Holder to the Company or of
the occurrence of any event in either case as a result of which any prospectus
relating to such Shelf Registration contains or would contain an untrue
statement of a material fact regarding such Electing Holder or such Electing
Holder's intended method of disposition of such Registrable Notes or omits to
state any material fact regarding such Electing Holder or such Electing Holder's
intended method of disposition of such Registrable Notes required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing, and promptly to furnish to the Company any
additional information required to correct and update any previously furnished
information or required so that such prospectus shall not contain, with respect
to such Electing Holder or the disposition of such Registrable Notes, an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing.

      (g) Until the expiration of two years after the Closing, the Company will
not, and will not permit any of its "affiliates" (as defined in Rule 144) to,
resell any of the Initial Notes that have been reacquired by any of them except
pursuant to an effective registration statement under the Securities Act.

      4. Registration Expenses. The Company agrees to bear and to pay or cause
to be paid promptly all expenses incident to the Company's performance of or

Initial Purchasers, any holder or any underwriter expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the prospectus included in such Registration Statement (or any amendment or
supplement thereto) and (ii) the Company and the Parent shall not be liable to
any indemnified party under this indemnity agreement with respect to the
Registration Statement or prospectus to the extent that any such loss, 


                                       19
   20

claim, damage or liability of such indemnified party results solely from an
untrue statement of a material fact contained in, or the omission of a material
fact from, the Registration Statement or prospectus which untrue statement or
omission was corrected in an amended or supplemented Registration Statement or
prospectus, if the person alleging such loss, claim, damage or liability was not
sent or given, at or prior to the written confirmation of such sale, a copy of
the amended or supplemented Registration Statement or prospectus if the Company
had previously furnished copies thereof to such indemnified party and if
delivery of a prospectus is required by the Securities Act and was not so made.
This indemnity agreement will be in addition to any liability which the Company
and the Parent may otherwise have.

      (b) In the case of a Shelf Registration, each holder agrees, severally and
not jointly, to indemnify and hold harmless the Company, the Parent, the Initial
Purchasers, each underwriter who participates in an offering of Registrable
Notes and the other selling holders and each of their respective directors and
officers (including each officer of each of the Company who signed the
Registration Statement) and each person, if any, who controls the Company and
the Parent, each Initial Purchaser, any underwriter or any other selling holder
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, against any and all losses, liabilities, claims, damages and
expenses described in the indemnity contained in Section 5(a) hereof, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or the prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company by such holder, as the case may be, expressly for use in the
Registration Statement (or any amendment thereto), or the prospectus (or any
amendment or supplement thereto); provided, however, that no such holder shall
be liable for any claims hereunder in excess of the amount of net proceeds
received by such holder from the sale of Registrable Notes pursuant to such
Shelf Registration Statement.

      (c) Each indemnified party shall give notice in writing as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. In case any such
action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party); provided, however, that if (i) the use of counsel chosen by
the indemnifying party to represent the indemnified party would present such
counsel with a conflict of interest, (ii) the actual or potential defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have been advised by counsel that there may be
one or more legal defenses available to it and/or other indemnified parties that
are different from or additional to those available to the indemnifying party,
or 


                                       20
   21

(iii) the indemnifying party shall not have employed counsel reasonably
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after receipt by the indemnifying party of notice of the
institution of such action, then, in each such case, the indemnifying party
shall not have the right to direct the defense of such action on behalf of such
indemnified party or parties and such indemnified party or parties shall have
the right to select separate counsel to defend such action on behalf of such
indemnified party or parties. After notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof and approval
by such indemnified party of counsel appointed to defend such action, the
indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof, unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the immediately preceding
sentence (it being understood, however, that in connection with such action the
indemnifying party shall not be liable for the reasonable fees and expenses of
more than one separate counsel (in addition to any local counsel) in any one
action or separate but substantially similar actions in the same jurisdiction
arising out of the same general allegations or circumstances, designated by the
Initial Purchasers in the case of paragraph (a) of this Section 5 or the Company
in the case of paragraph (b) of this Section 5, representing the indemnified
parties under such paragraph (a) or paragraph (b), as the case may be, who are
parties to such action or actions) or (ii) the indemnifying party has authorized
in writing the employment of counsel for the indemnified party at the expense of
the indemnifying party. No indemnifying party shall, without the prior written
consent of the indemnified parties, settle or compromise or consent to the entry
of any judgment with respect to any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever in respect of which indemnification or contribution could be
sought under this Section 5 (whether or not the indemnified parties are actual
or potential parties thereof), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

      (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for reasonable fees and
expenses of counsel and the indemnifying party is obligated to reimburse the
indemnified party under the foregoing provisions of this Section 5, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 5(a)(ii) hereof effected without its written
consent if (i) such settlement is entered into more than 20 business days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least five business days prior to such settlement being entered into and (iii)
such indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior


                                       21
   22

to the date of such settlement.

      (e) If the indemnification provided for in any of the indemnity provisions
set forth in this Section 5 is for any reason unavailable to or insufficient to
hold harmless an indemnified party in respect of any losses, liabilities,
claims, damages or expenses referred to therein, then each indemnifying party
shall contribute to the aggregate amount of such losses, liabilities, claims,
damages and expenses incurred by such indemnified party, as incurred, (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company, the Parent, the Initial Purchaser and the holders, from the
offering of the Exchange Notes or Registrable Notes included in such offering or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company, the Parent, the Initial Purchasers, and the holders, in connection with
the statements or omissions which resulted in such losses, liabilities, claims,
damages or expenses, as well as any other relevant equitable considerations. The
relative fault of the Company, the Parent, the Initial Purchasers, and the
holders shall be determined by reference to, among other things, whether any
such untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company, the Parent, the Initial Purchasers or the holders and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company, the Parent, the Initial
Purchasers and the holders of the Registrable Notes 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 Initial Purchasers were treated as one entity,
and the holders were treated as one entity, for such purpose) or by another
method of allocation which does not take account of the equitable considerations
referred to above in this Section 5. The aggregate amount of losses,
liabilities, claims, damages and expenses incurred by an indemnified party and
referred to above in this Section 5 shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in investigating,
preparing or defending against any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue or alleged untrue statement or
omission or alleged omission. 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. For purposes of this Section 5, each person, if any, who
controls an Initial Purchaser or holder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to
contribution as such Initial Purchaser or holder, and each director of the
Company and each officer of the Company who signed the Registration Statement,
and each person, if any, who controls the Company and the Parent within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
shall have the same rights to contribution as the Company and the Parent. The
parties hereto agree that any underwriting discount or 


                                       22
   23

commission or reimbursement of fees paid to any Initial Purchaser pursuant to
the Purchase Agreement shall not be deemed to be a benefit received by any
Initial Purchaser in connection with the offering of the Exchange Notes or
Registrable Notes in such offering.

      6. Underwritten Offerings. (a) Selection of Underwriters. If any of the
Registrable Notes covered by the Shelf Registration are to be sold pursuant to
an underwritten offering, the managing underwriter or underwriters thereof shall
be designated by Electing Holders holding at least a majority in aggregate
principal amount at maturity of the Registrable Notes to be included in such
offering, provided that such designated managing underwriter or underwriters is
or are reasonably acceptable to the Company.

      (b) Participation by Holders. Each holder of Registrable Notes hereby
agrees with each other such holder that no such holder may participate in any
underwritten offering hereunder unless such holder (i) agrees to sell such
holder's Registrable Notes on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

      7. Rules 144 and 144A. Each of the Parent and the Company covenants to the
holders of Registrable Notes that to the extent the Company and the Parent shall
be required to do so under the Exchange Act, each of the Company and the Parent
shall use its reasonable best efforts to timely file the reports required to be
filed by it under the Exchange Act or the Securities Act and the rules and
regulations adopted by the Commission thereunder, and shall take such further
action as any holder of Registrable Notes may reasonably request, all to the
extent required from time to time to enable such holder to sell Registrable
Notes without registration under the Securities Act within the limitations of
the exemption provided by Rules 144 and 144A under the Securities Act, as such
Rule may be amended from time to time, or any similar or successor rule or
regulation hereafter adopted by the Commission. Upon the request of any holder
of Registrable Notes in connection with that holder's sale pursuant to Rule 144
or 144A, the Company and the Parent shall deliver to such holder a written
statement as to whether it has complied with such requirements.

      8. Miscellaneous. (a) No Inconsistent Agreements. Neither the Parent nor
the Company has, as of the date hereof, entered into nor will the Parent or the
Company on or after the date of this Agreement enter into any agreement which is
inconsistent with the rights granted to the holders of Registrable Notes 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 Parent's or the
Company's other issued and outstanding securities under any such 


                                       23
   24

agreements.

      (b) Specific Performance. The parties hereto acknowledge that there would
be no adequate remedy at law if the Company or the Parent fails to perform any
of their respective obligations hereunder and that the Initial Purchasers and
the holders from time to time of the Registrable Notes may be irreparably harmed
by any such failure, and accordingly agree that the Initial Purchasers and such
holders, in addition to any other remedy to which they may be entitled at law or
in equity, shall be entitled to compel specific performance of the obligations
of the Company and the Parent under this Agreement in accordance with the terms
and conditions of this Agreement, in any court of the United States or any State
thereof having jurisdiction.

      (c) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company have obtained the written consent of holders of at
least a majority in aggregate principal amount of the outstanding Registrable
Notes affected by such amendment, modification, supplement, waiver or departure;
provided, however, that no amendment, modification, supplement or waiver or
consent to any departure from the provisions of Section 5 hereof shall be
effective as against any holder of Registrable Notes unless consented to in
writing by such holder.

      (d) 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 Company by means of a notice given in accordance with the provisions of this
Section 8(d), which address initially is, with respect to an Initial Purchaser,
the address set forth in the Purchase Agreement; and (ii) if to the Company or
the Parent, initially at the Company's address set forth in the Purchase
Agreement and thereafter at such other address, notice of which is given in
accordance with the provisions of this Section 8(d).

      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 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.


                                       24
   25

      (e) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors, assigns and transferees of each of the
panics, including, without limitation and without the need for an express
assignment subsequent holders; provided, however, that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Notes in violation of the terms hereof or of the Purchase Agreement or the
Indenture. If any transferee of any holder shall acquire Registrable Notes, in
any manner, whether by operation of law or otherwise, such Registrable Notes
shall be held subject to all of the terms of this Agreement, and by taking and
holding such Registrable Notes, such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement, including the restrictions on resale set forth in this Agreement and,
if applicable, the Purchase Agreement, and such person shall be entitled to
receive the benefits hereof.

      (f) Third Party Beneficiary. The holders shall be third party
beneficiaries to the agreements made hereunder between the Company and the
Parent, on the one hand, and the Initial Purchasers, on the other hand, and the
Initial Purchasers shall have the right to enforce such agreements directly to
the extent they deem such enforcement necessary or advisable to protect their
rights 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 AND CONSTRUED IN
ACCORDANCE WITH 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.

      IN WITNESS WHEREOF, the parties have executed this Agreement as of the
