filed with the Commission as soon as practicable after the Closing Date, but in

                                       3
<PAGE>

     (b)    The Company and the Guarantors shall cause the Exchange Offer
Registration Statement to be effective continuously and shall keep the Exchange
Offer open for a period of not less than the minimum period required under
applicable federal and state securities laws to Consummate the Exchange Offer;
provided, however, that in no event shall such period be less than 30 days after
the date notice of the Exchange Offer is mailed to the Holders. The Company
shall cause the Exchange Offer to comply with all applicable federal and state
securities laws. No securities other than the Notes shall be included in the
Exchange Offer Registration Statement. The Company shall use its best efforts to
cause the Exchange Offer to be Consummated on the earliest practicable date
after the Exchange Offer Registration Statement has become effective, but in no
event later than 30 days after the date on which the Exchange Offer Registration
Statement has been declared effective, unless required by any applicable federal
securities laws.

     (c)    The Company and the Guarantors shall indicate in a "Plan of
Distribution" section contained in the Prospectus forming a part of the Exchange
Offer Registration Statement that any Broker-Dealer who holds Initial Notes that
are Transfer Restricted Securities and that were acquired for its own account as
a result of market-making activities or other trading activities (other than
Transfer Restricted Securities acquired directly from the Company), may exchange
such Initial Notes pursuant to the Exchange Offer; however, such Broker-Dealer
may be deemed to be an "underwriter" within the meaning of the Securities Act
and must, therefore, deliver a prospectus meeting the requirements of the
Securities Act in connection with any resales of the Exchange Notes received by
such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement
may be satisfied by the delivery by such Broker-Dealer of the Prospectus
contained in the Exchange Offer Registration Statement. Such "Plan of
Distribution" section shall also contain all other information with respect to
such resales by Broker-Dealers that the Commission may require in order to
permit such resales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Notes held by any such
Broker-Dealer except to the extent required by the Commission as a result of a
change in policy after the date of this Agreement.

            The Company and the Guarantors shall use their best efforts to keep
the Exchange Offer Registration Statement continuously effective, supplemented
and amended as required by the provisions of Section 6(c) below to the extent
necessary to ensure that it is available for resales of Notes acquired by
Broker-Dealers for their own accounts as a result of market-making activities or
other trading activities, and to ensure that it conforms with the requirements
of this Agreement, the Securities Act and the policies, rules and regulations of
the Commission as announced from time to time, for a period ending on the
earlier of (i) 180 days from the date on which the Exchange Offer Registration
Statement is declared effective and (ii) the date on which a Broker-Dealer is no
longer required to deliver a prospectus in connection with market-making or
other trading activities.

            The Company and the Guarantors shall provide sufficient copies of
the latest version of such Prospectus to Broker-Dealers promptly upon request at
any time during such 180 day (or shorter as provided in the foregoing sentence)
period in order to facilitate such resales.

Section 4.  Shelf Registration

     (a)    Shelf Registration.  If (i) the Company is not required to file an
            ------------------
Exchange Offer Registration Statement or to consummate the Exchange Offer
because the Exchange Offer is not permitted by applicable law or Commission
policy (after the procedures set forth in Section 6(a) below have been complied
with) or (ii) with respect to any Holder of Transfer Restricted Securities
(other than a


                                       4

Restriced Securities from a director or officer of the Company) and (A) such
Holder is prohibited by applicable law or Commission policy from participating
in the Exchange Offer, or (B) such Holder may not resell the Exchange Notes
acquired by it in the Exchange Offer to the public without delivering a
prospectus and that the Prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales by such Holder, or
(C) such Holder is a Broker-Dealer and holds Initial Notes acquired directly
from the Company or one of its affiliates, then, upon such Holder's request
delivered to the Company not later than 20 days after the consummation of the
Exchange Offer, the Company and the Guarantors shall:

          (x)  cause to be filed a shelf registration statement pursuant to Rule
     415 under the Securities Act, which may be an amendment to the Exchange
     Offer Registration Statement (in either event, the "Shelf Registration
                                                         ------------------
     Statement") on or prior to 60 days after the earlier to occur of (1) the
     ---------
     date on which the Company determines that it is not required to file the
     Exchange Offer Registration Statement and (2) the date on which the Company
     receives notice from a Holder of Transfer Restricted Securities as
     contemplated by clause (ii) above 60 days after such earlier date being the
     "Shelf Filing Deadline"), which Shelf Registration Statement shall provide
      ---------------------
     for resales of all Transfer Restricted Securities the Holders of which
     shall have provided the information required pursuant to Section 4(b)
     hereof; and

          (y)  use their best efforts to cause such Shelf Registration Statement
     to be declared effective by the Commission on or before 150 days after the
     Shelf Filing Deadline.

The Company and the Guarantors shall use their best efforts to keep such Shelf
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Sections 6(b) and (c) hereof to the extent
necessary to ensure that it is available for resales of Notes by the Holders of
Transfer Restricted Securities entitled to the benefit of this Section 4(a), and
to ensure that it conforms with the requirements of this Agreement, the
Securities Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years following the
effective date of such Shelf Registration Statement (or shorter period that will
terminate when all the Notes covered by such Shelf Registration Statement have
been sold pursuant to such Shelf Registration Statement).

     (b)    Provision by Holders of Certain Information in Connection with the
            ------------------------------------------------------------------
Shelf Registration Statement.  No Holder of Transfer Restricted Securities may
----------------------------
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 business days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. Each Holder as to which any Shelf Registration
Statement is being effected agrees to furnish promptly to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

Section 5.  Liquidated Damages

            If (i) any of the Registration Statements required by this Agreement

filing in this Agreement, (ii) any of such Registration Statements has not been
declared effective by the Commission on or prior to the date specified for such
effectiveness in this Agreement (the "Effectiveness Target Date"), (iii) the
                                      -------------------------
Exchange Offer has not been Consummated within 30 business days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for


                                       5
<PAGE>

its intended purpose without being succeeded immediately by a post-effective
amendment to such Registration Statement that cures such failure and that is
itself immediately declared effective (each such event referred to in
clauses (i) through (iv), a "Registration Default"), the Company and the
                             --------------------
Guarantors hereby jointly and severally agree to pay to each Holder of Transfer
Restricted Securities affected thereby liquidated damages in an amount equal to
$.05 per week per $1,000 in principal amount of Transfer Restricted Securities
held by such Holder for each week or portion thereof that the Registration
Default continues for the first 90-day period immediately following the
occurrence of such Registration Default.  The amount of the liquidated damages
shall increase by an additional $.05 per week per $1,000 in principal amount of
Transfer Restricted Securities with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
liquidated damages of $.50 per week per $1,000 in principal amount of Transfer
Restricted Securities.  Following the cure of all Registration Defaults relating
to any particular Transfer Restricted Securities, liquidated damages payable
with respect to the Transfer Restricted Securities as a result of such clause
(i), (ii), (iii) or (iv), as applicable, shall cease.

            All obligations of the Company and the Guarantors set forth in the
preceding paragraph that are outstanding with respect to any Transfer Restricted
Security at the time such security ceases to be a Transfer Restricted Security
shall survive until such time as all such obligations with respect to such Note
shall have been satisfied in full.

            (i)  If in the reasonable opinion of counsel to the Company there
is a question as to whether the Exchange Offer is permitted by applicable law,

favorable decision from the Commission allowing the Company and the Guarantors
to Consummate an Exchange Offer for such Initial Notes. The Company and the
Guarantors each hereby agree to pursue the issuance of such a decision to the

to participate in a distribution of the securities to be acquired in the
Exchange Offer (1) could not under

applicable, of Regulation S-K if the resales are of Exchange Notes obtained by
such Holder in exchange for Initial Notes acquired by such Holder directly from
the Company.

     (b)    Shelf Registration Statement.  In connection with the Shelf
            ----------------------------

provisions of Section 6(c) below and shall use their best efforts to effect such
registration to permit the sale of the Transfer Restricted Securities being sold

with the Commission a Registration Statement relating to the registration on any
appropriate form under the Securities Act, which form shall be available for the
sale of the Transfer Restricted Securities in accordance with the intended
method or methods of distribution thereof.

            ------------------

Transfer Restricted Securities (including, without limitation, any Registration
Statement and the related Prospectus required to permit resales of Notes by
Broker-Dealers), the Company shall:

continuously effective and provide all requisite financial statements
(including, if required by the Securities Act or any regulation thereunder,
financial statements of the Guarantors for the period specified in Section 3 or
4 of this Agreement, as applicable; upon the occurrence of any event that would
cause any such Registration Statement or the Prospectus contained therein (A) to

usable for resale of Transfer Restricted Securities during the period required
by this Agreement, the Company shall file promptly an appropriate amendment to
such Registration Statement, in the case of clause (A), correcting any such
misstatement or omission, and, in the case of either clause (A) or (B), use its
best efforts to cause such amendment to be declared effective and such
Registration Statement and the related Prospectus to become usable for their
intended purpose(s) as soon as practicable thereafter;

            (ii) prepare and file with the Commission such amendments and post-
effective amendments to the Registration Statement as may be necessary to keep
the Registration Statement effective for the applicable period set forth in
Section 3 or 4 hereof, as applicable, or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold; cause the Prospectus to be supplemented by any required
Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424
under the Securities Act, and to comply fully with the applicable provisions of
Rules 424 and 430A under the Securities Act in a timely manner; and comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such Registration Statement during the applicable period

            (iii)  advise the selling Holders promptly and, if requested by
such Persons, to confirm such advice in writing, (A) when the Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to any Registration Statement or any post-effective amendment thereto,
when the same has become effective, (B) of any request by the Commission for
amendments to the Registration Statement or amendments or supplements to the
Prospectus or for additional information relating thereto, (C) of the issuance
by the Commission of any stop order suspending the effectiveness of the
Registration Statement under the Securities Act or of the suspension by any
state securities commission of the qualification of the Transfer Restricted
Securities for offering or sale in any jurisdiction, or the initiation of any
proceeding for any of the preceding purposes, (D) of the existence of any fact
or the happening of any event that makes any statement of a material fact made
in the Registration Statement, the Prospectus, any amendment or supplement
thereto, or any document incorporated by reference therein untrue, or that
requires the making of any additions to or changes in the Registration Statement
or the Prospectus in order to make the statements therein not misleading. If at
any time the Commission shall issue any stop order suspending the effectiveness
of the Registration Statement, or any state securities commission or other
regulatory authority shall issue an order suspending the qualification or
exemption from qualification of the Transfer Restricted Securities under state
securities or Blue Sky laws, the Company and the Guarantors shall use their best
efforts to obtain the withdrawal or lifting of such order at the earliest
possible time;

            (iv) furnish without charge to each of the Initial Purchasers and
each selling Holder named in any Registration Statement, before filing with the
Commission, copies of any Registration Statement or any Prospectus included
therein or any amendments or supplements to any such Registration Statement or
Prospectus (including all documents incorporated by reference after the initial
filing of such Registration Statement), which documents will be subject to the
review of such Persons in connection with such sale, if any, for a period of at
least five business days, and the Company will not file any such Registration
Statement or Prospectus or any amendment or supplement to any such Registration
Statement or Prospectus (including all such documents incorporated by reference)
to which an Initial Purchaser or Holder of Transfer Restricted Securities
covered by such Registration Statement shall reasonably object in writing within
five business days after the receipt thereof (such objection to be deemed timely
made upon confirmation of telecopy transmission within such period). The
objection of any such Person shall be deemed to be reasonable if such
Registration Statement, amendment, Prospectus or supplement, as applicable, as
proposed to be filed, contains a material misstatement or omission;

            (v)  promptly prior to the filing of any document that is to be
incorporated by reference into a Registration Statement or Prospectus, provide
copies of such document to the Initial Purchasers and to each selling Holder
named in any Registration Statement, make available the Company's
representatives and representatives of the Guarantors for discussion of such
document and other customary due diligence matters, and include such information
in such document prior to the filing thereof as such selling Holders reasonably
may request;

            (vi) make available at reasonable times for inspection by the
Initial Purchasers and each Holder, and any attorney or accountant retained by
such Persons, all financial and other records, pertinent corporate documents and
properties of the Company and the Guarantors and cause the Company's and the
Guarantors' officers, directors and employees to supply all information
reasonably requested by any such Holder, Initial Purchaser, attorney or
accountant in connection with such Registration Statement subsequent to the
filing thereof and prior to its effectiveness;

            (vii)  if requested by any selling Holders promptly incorporate in
any Registration Statement or Prospectus, pursuant to a supplement or post-
effective amendment if necessary, such information as such selling Holders may
reasonably request to have included therein, including, without limitation,
information relating to the "Plan of Distribution" of the Transfer Restricted
Securities, information with respect to the principal amount of Transfer
Restricted Securities being sold, the purchase price being paid therefor and any
other terms of the offering of the Transfer Restricted Securities to be


                                       8

sold in such offering; and make all required filings of such Prospectus
supplement or post-effective amendment as soon as practicable after the Company
is notified of the matters to be incorporated in such Prospectus supplement or
post-effective amendment;

            (viii)  cause the Transfer Restricted Securities covered by the
Registration Statement to be rated with the appropriate rating agencies, if so
requested by the Holders of a majority in aggregate principal amount of Notes
covered thereby;

            (ix) furnish to each selling Holder upon request, without charge,
at least one copy of the Registration Statement, as first filed with the
Commission, and of each amendment thereto, including financial statements and
schedules, all documents incorporated by reference therein and all exhibits
(including exhibits incorporated therein by reference);

            (x)  deliver to each selling Holder, without charge, as many copies
of the Prospectus (including each preliminary prospectus) and any amendment or
supplement thereto as such Persons reasonably may request; the Company and the
Guarantors hereby consent to the use of the Prospectus and any amendment or
supplement thereto by each of the selling Holders in connection with the
offering and the sale of the Transfer Restricted Securities covered by the
Prospectus or any amendment or supplement thereto;

            (xi) enter into, and cause the Guarantors to enter into, such
customary agreements, and make, and cause the Guarantors to make, such customary
representations and warranties, and take all such other actions in connection
therewith in order to expedite or facilitate the disposition of the Transfer
Restricted Securities pursuant to any Registration Statement contemplated by
this Agreement, all to such extent as may be reasonably requested by any Initial
Purchaser or by any Holder of Transfer Restricted Securities or underwriter in
connection with any sale or resale pursuant to any Registration Statement
contemplated by this Agreement; and the Company and the Guarantors shall:

            (A)  furnish to each Initial Purchaser and each selling Holder, in
     such substance and scope as they may request upon the date of the
     Consummation of the Exchange Offer and, if applicable, the effectiveness of
     the Shelf Registration Statement a certificate, dated the date of
     Consummation of the Exchange Offer or the date of effectiveness of the
     Shelf Registration Statement, as the case may be, signed by (y) the
     President or any Vice President and (z) a principal financial or accounting
     officer of each of the Company and the Guarantors, confirming, as of the
     date thereof, the matters set forth in paragraphs (i), (ii) and (iii) of
     Section 5(e) of the Purchase Agreement and such other matters as such
     parties may reasonably request;

            (B)  set forth in full in such agreements the indemnification
     provisions and procedures of Section 8 hereof with respect to all parties
     to be indemnified pursuant to said Section; and

            (C)  deliver such other documents and certificates as may be
     reasonably requested by such parties to evidence compliance with clause (A)
     above and with any customary conditions contained in any agreement entered
     into by the Company or the Guarantors pursuant to this clause (xi), if any.

            If at any time the representations and warranties of the Company and
the Guarantors contemplated in clause (A)(1) above cease to be true and correct,
the Company or the Guarantors shall so advise the Initial Purchasers and each
selling Holder promptly and, if requested by such Persons, shall confirm such
advice in writing;


                                       9
<PAGE>

            (xii)  prior to any public offering of Transfer Restricted
Securities, cooperate with, and cause the Guarantors to cooperate with, the
selling Holders, the underwriter(s), if any, and their respective counsel in
connection with the registration and qualification of the Transfer Restricted
Securities under the securities or Blue Sky laws of such jurisdictions as the
selling Holders or underwriter(s) may request and do any and all other acts or
things necessary or advisable to enable the disposition in such jurisdictions of
the Transfer Restricted Securities covered by the Shelf Registration Statement;
provided, however, that neither the Company nor the Guarantors shall be required
to register or qualify as a foreign corporation where it is not then so
qualified or to take any action that would subject it to the service of process
in suits or to taxation, other than as to matters and transactions relating to
the Registration Statement, in any jurisdiction where it is not then so subject;

            (xiii)  shall issue, upon the request of any Holder of Initial
Notes covered by the Shelf Registration Statement, Exchange Notes, having an
aggregate principal amount equal to the aggregate principal amount of Initial
Notes surrendered to the Company by such Holder in exchange therefor or being
sold by such Holder; such Exchange Notes to be registered in the name of such
Holder or in the name of the purchaser(s) of such Notes, as the case may be; in
return, the Initial Notes held by such Holder shall be surrendered to the
Company for cancellation;

            (xiv)  cooperate with, and cause the Guarantors to cooperate with,
the selling Holders to facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to be sold and not
bearing any restrictive legends; and enable such Transfer Restricted Securities
to be in such denominations and registered in such names as the Holders may
request at least two business days prior to any sale of Transfer Restricted
Securities;

            (xv) use its reasonable best efforts to cause the Transfer
Restricted Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to enable the seller or sellers thereof or the underwriter(s), if any,
to consummate the disposition of such Transfer Restricted Securities, subject to
the proviso contained in clause (xii) above;

            (xvi)  if any fact or event contemplated by clause (c)(iii)(D)
above shall exist or have occurred, prepare a supplement or post-effective
amendment to the Registration Statement or related Prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchasers of Transfer Restricted Securities, the
Prospectus will not contain an untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein not misleading;

            (xvii)  provide a CUSIP number for all Transfer Restricted
Securities not later than the effective date of the Registration Statement and
provide the Trustee under the Indenture with printed certificates for the
Transfer Restricted Securities which are in a form eligible for deposit with the
Depositary Trust Company;

            (xviii)  otherwise use its reasonable best efforts to comply with
all applicable rules and regulations of the Commission, and make generally
available to its security holders, as soon as practicable, a consolidated
earnings statement meeting the requirements of Rule 158 (which need not be
audited) for the twelve-month period beginning with the first month of the
Company's first fiscal quarter commencing after the effective date of the
Registration Statement;

            (xix)  cause the Indenture to be qualified under the Trust
Indenture Act not later than the effective date of the first Registration
Statement required by this Agreement, and, in connection therewith, cooperate,
and cause the Guarantors to cooperate with the Trustee and the Holders of Notes
to


                                      10
<PAGE>

effect such changes to the Indenture as may be required for such Indenture to
be so qualified in accordance with the terms of the Trust Indenture Act; and to
execute, and cause the Guarantors to execute, and use its best efforts to cause
the Trustee to execute, all documents that may be required to effect such
changes and all other forms and documents required to be filed with the
Commission to enable such Indenture to be so qualified in a timely manner;

            (xx) cause all Transfer Restricted Securities covered by the
Registration Statement to be listed on each securities exchange on which similar
securities issued by the Company are then listed if requested by the Holders of
a majority in aggregate principal amount of Initial Notes or the managing
underwriter(s), if any; and

            (xxi)  provide promptly to each Holder upon request each document
filed with the Commission pursuant to the requirements of Section 13 and Section
15 of the Exchange Act.

            Each Holder agrees by acquisition of a Transfer Restricted Security
that, upon receipt of any notice from the Company of the existence of any fact
of the kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the
applicable Registration Statement until such Holder's receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof,
or until it is advised in writing (the "Advice") by the Company that the use of
                                        ------
the Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus.  If
so directed by the Company, each Holder will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of such notice.  In the event
the Company shall give any such notice, the time period regarding the
effectiveness of such Registration Statement set forth in Section 3 or 4 hereof,
as applicable, shall be extended by the number of days during the period from
and including the date of the giving of such notice pursuant to Section
6(c)(iii)(D) hereof to and including the date when each selling Holder covered
by such Registration Statement shall have received the copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof or
shall have received the Advice; however, no such extension shall be taken into
account in determining whether liquidated damages are due pursuant to Section 5
hereof or the amount of such liquidated damages, it being agreed that the
Company's option to suspend use of a Registration Statement pursuant to this
paragraph shall be treated as a Registration Default for purposes of Section 5.

Section 7.  Registration Expenses

     (a)    All expenses incident to the Company's or the Guarantors'
performance of or compliance with this Agreement will be borne by the Company or
the Guarantors, regardless of whether a Registration Statement becomes
effective, including without limitation: (i) all registration and filing fees
and expenses (including filings made by any Initial Purchaser or Holder with the
NASD; (ii) all fees and expenses of compliance with federal securities and state
Blue Sky or securities laws; (iii) all expenses of printing (including printing
certificates for the Exchange Notes to be issued in the Exchange Offer and
printing of Prospectuses), messenger and delivery services and telephone; (iv)
all fees and disbursements of counsel for the Company, the Guarantors and,
subject to Section 7(b) below, the Holders of Transfer Restricted Securities;
(v) all application and filing fees in connection with listing the Exchange
Notes on a national securities exchange or automated quotation system pursuant
to the requirements thereof; and (vi) all fees and disbursements of independent
certified public accountants of the Company and the Guarantors (including the

such performance).


                                      11
<PAGE>

            The Company will, in any event, bear its and the Guarantors'
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expenses
of any annual audit and the fees and expenses of any Person, including special
experts, retained by the Company or the Guarantors.

     (b)    In connection with the Shelf Registration Statement, the Company
and the Guarantors will reimburse the Initial Purchasers and the Holders of
Transfer Restricted Securities being registered pursuant to the Shelf
Registration Statement for the reasonable fees and disbursements of not more
than one counsel, who shall be Latham & Watkins or such other counsel as may be
chosen by the Holders of a majority in principal amount of the Transfer
Restricted Securities for whose benefit the Shelf Registration Statement is
being prepared.

Section 8.  Indemnification

     (a)    The Company and the Guarantors, jointly and severally, agree to
indemnify and hold harmless (i) each Holder and (ii) each person, if any, who
controls (within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act) any Holder (any of the persons referred to in this clause
(ii) being hereinafter referred to as a "controlling person") and (iii) the
respective officers, directors, partners, employees, representatives and agents
of any Holder or any controlling person (any person referred to in clause (i),
(ii) or (iii) may hereinafter be referred to as an "Indemnified Holder"), to the
                                                    ------------------
fullest extent lawful, from and against any and all losses, claims, damages,
liabilities, judgments, actions and expenses (including without limitation and
as incurred, reimbursement of all reasonable costs of investigating, preparing,
pursuing, settling, compromising, paying or defending any claim or action, or
any investigation or proceeding by any governmental agency or body, commenced or
threatened, including the reasonable fees and expenses of counsel to any
Indemnified Holder), joint or several, directly or indirectly caused by, related
to, based upon, arising out of or in connection with any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement or Prospectus (or any amendment or supplement thereto), or 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,
except insofar as such losses, claims, damages, liabilities or expenses are
caused by an untrue statement or omission or alleged untrue statement or
omission that is made in reliance upon and in conformity with information
relating to any of the Holders furnished in writing to the Company by any of the
Holders expressly for use therein. This indemnity agreement shall be in addition
to any liability which the Company may otherwise have.

            In case any action or proceeding (including any governmental or
regulatory investigation or proceeding) shall be brought or asserted against any
of the Indemnified Holders with respect to which indemnity may be sought against
the Company or the Guarantors, such Indemnified Holder (or the Indemnified
Holder controlled by such controlling person) shall promptly notify the Company
and the Guarantors in writing (provided, that the failure to give such notice
shall not relieve the Company or the Guarantors of their respective obligations
pursuant to this Agreement).  Such Indemnified Holder shall have the right to
employ its own counsel in any such action and the fees and expenses of such
counsel shall be paid, as incurred, by the Company and the Guarantors
(regardless of whether it is ultimately determined that an Indemnified Holder is
not entitled to indemnification hereunder).  The Company and the Guarantors
shall not, in connection with any one such action or proceeding or separate but
substantially similar or related actions or proceedings in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) at any time for such Indemnified Holders, which
firm shall be designated by the Holders.  The Company shall be liable for any
settlement of any such action or proceeding effected with the Company's prior
written consent, which consent shall not be withheld unreasonably, and the
Company agrees to indemnify and hold harmless any Indemnified Holder


                                      12
<PAGE>

from and against any loss, claim, damage, liability or expense by reason of any
settlement of any action effected with the written consent of the Company. The
Company shall not, without the prior written consent of each Indemnified Holder,
settle or compromise or consent to the entry of judgment in or otherwise seek to
terminate any pending or threatened action, claim, litigation or proceeding in
respect of which indemnification or contribution may be sought hereunder
(whether or not any Indemnified Holder is a party thereto), unless such
settlement, compromise, consent or termination includes an unconditional release
of each Indemnified Holder from all liability arising out of such action, claim,
litigation or proceeding.

     (b)    Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Company and the Guarantors and
their respective directors, officers of the Company who sign a Registration
Statement, and any person controlling (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) the Company, and the
respective officers, directors, partners, employees, representatives and agents
of each such person, to the same extent as the foregoing indemnity from the
Company and the Guarantors to each of the Indemnified Holders, but only with
respect to claims and actions based on information relating to such Holder
furnished in writing by such Holder expressly for use in any Registration
Statement. In case any action or proceeding shall be brought against the Company
or its directors or officers or any such controlling person in respect of which
indemnity may be sought against a Holder of Transfer Restricted Securities, such
Holder shall have the rights and duties given the Company and the Company or its
directors or officers or such controlling person shall have the rights and
duties given to each Holder by the preceding paragraph. In no event shall the
liability of any selling Holder hereunder be greater in amount than the dollar
amount of the proceeds received by such Holder upon the sale of the Securities
giving rise to such indemnification obligation.

     (c)    If the indemnification provided for in this Section 8 is
unavailable to an indemnified party under Section 8(a) or Section 8(b) hereof
(other than by reason of exceptions provided in those Sections) in respect of
any losses, claims, damages, liabilities, judgments, actions or expenses
referred to therein, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Guarantors, on the one hand,
and the Holders on the other hand, from the Initial Placement (which in the case
of the Company shall be deemed to be equal to the total net proceeds from the
Initial Placement as set forth in the "Use of Proceeds" section of the offering
memorandum prepared in connection with the Initial Placement and the liquidated
damages which did not become payable as a result of the filing of the
Registration Statement resulting in such losses, claims, damages, liabilities,
judgments actions or expenses) and such Registration Statement, or if such
allocation is not permitted by applicable law, the relative fault of the Company
and the Guarantors on the one hand, and of the Indemnified Holder, on the other
hand, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative fault of the Company on the one hand and
of the Indemnified Holder 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 or by the Indemnified Holder and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set
forth in the second paragraph of Section 8(a), any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim.

            The Company, the Guarantors and each Holder of Transfer Restricted
Securities agree that it would not be just and equitable if contribution
pursuant to this Section 8(c) were determined by pro rata allocation (even if
the Holders were treated as one entity for such purpose) or by any other method
of


                                      13
<PAGE>

allocation which does not take account of the equitable considerations
referred to in the immediately preceding paragraph.  The amount paid or payable
by an indemnified party as a result of the losses, claims, damages, liabilities
or expenses referred to in the immediately preceding paragraph 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 8, none of the Holders (and its related Indemnified
Holders) shall be required to contribute, in the aggregate, any amount in excess
of the amount by which the total received by such Holder with respect to the
sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages which 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.  The Holders' obligations to contribute pursuant to this
Section 8(c) are several in proportion to the respective principal amount of
Initial Notes held by each of the Holders hereunder and not joint.

Section 9.  Rule 144A

            The Company and the Guarantors each hereby agrees with each Holder,
for so long as any Transfer Restricted Securities remain outstanding, to make
available to any Holder or beneficial owner of Transfer Restricted Securities in
connection with any sale thereof and any prospective purchaser of such Transfer
Restricted Securities from such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Securities Act in order to permit resales
of such Transfer Restricted Securities pursuant to Rule 144A.

Section 10. Participation in Underwritten Registrations

            No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all reasonable questionnaires, powers of attorney, indemnities,
underwriting agreements, lock-up letters and other documents required under the
terms of such underwriting arrangements.

Section 11. Miscellaneous

     (a)    Remedies.  The Company and the Guarantors each hereby agrees that
            --------
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Agreement and hereby agree to
waive the defense in any action for specific performance that a remedy at law
would be adequate.

     (b)    No Inconsistent Agreements.  The Company will not, and will cause
            --------------------------
the Guarantors not to, on or after the date of this Agreement enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders 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 Company's securities under any agreement in effect on the date hereof.

     (c)    Adjustments Affecting the Notes.  The Company will not take any
            -------------------------------
action, or permit any change to occur, with respect to the Notes that would
materially and adversely affect the ability of the Holders to Consummate any
Exchange Offer.


                                      14
<PAGE>

     (d)    Amendments and Waivers.  The provisions of this Agreement may not be
            ----------------------
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless the Company has obtained the
written consent of Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities. Notwithstanding the foregoing, a waiver or
consent to departure from the provisions hereof that relates exclusively to the
rights of Holders whose securities are being tendered pursuant to the Exchange
Offer and that does not affect directly or indirectly the rights of other
Holders whose securities are not being tendered pursuant to such Exchange Offer
may be given by the Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities being tendered or registered; provided that, with
respect to any matter that directly or indirectly affects the rights of any
Initial Purchaser hereunder, the Company shall obtain the written consent of
each such Initial Purchaser with respect to which such amendment, qualification,
supplement, waiver, consent or departure is to be effective.

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

            (i)  if to a Holder, at the address set forth on the records of the
Registrar under the Indenture, with a copy to the Registrar under the Indenture;
