        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

        of such Holder, the principal amount of Registrable Securities delivered
        for exchange and a statement that such Holder is withdrawing its
        election to have such Securities exchanged.

                As soon as practicable after the last Exchange Date, the Company
        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        thereof tendered and not validly withdrawn pursuant to the Exchange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

        surrendered by such Holder.

The Company shall use its best efforts to complete the Exchange Offer as
provided above and shall comply with the applicable requirements of the 1933

   7

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.

                (b)     In the event that (i) the Company determines 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 September 23, 1999 or (iii) in the opinion of counsel for the
Placement Agents addressed to the Company and the Guarantor 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 by a
Holder that (A) is or was prohibited by law or Commission policy from
participating in the Exchange Offer or (B) may not resell the Exchange
Securities acquired by it in the Exchange Offer to the public without delivering
a prospectus and the Prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales by such Holder or (C)
is a Broker-Dealer and holds Registrable Securities acquired directly from the
Company or any of its Affiliates, the Company shall use its best efforts to
cause to be filed as soon as practicable after such determination, date or
receipt of such opinion of counsel by the Company, 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 Company and the Guarantor 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 Company and the Guarantor
shall use their best 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 Company agrees to use its
best 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 Company further
agrees to supplement or amend the Shelf Registration Statement if required by
the rules, regulations or instructions applicable to the registration form used
by the Company 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 Shelf Holder with respect to information relating to
such Shelf Holder, and to use its best efforts to cause any such amendment to
become effective and such Shelf Registration Statement to become usable as soon
as thereafter practicable. The Company agrees to furnish to the Shelf Holders
copies of any such supplement or amendment promptly after its being used or
filed with the SEC.

                (c)     The Company 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; provided further
that if the offering of Registrable Securities pursuant to a Shelf Registration
Statement is interfered with as described in the previous sentence by reason of
any information relating to a Shelf Holder furnished to the Company in writing
by such Shelf Holder expressly for use in such Shelf Registration Statement,
then the provisions of the following sentence shall be inapplicable with respect
to such Shelf Holder. In the event that either the Exchange Offer is not
consummated or any Shelf Registration Statement required to be filed pursuant to
this Agreement is not declared effective on or prior to September 23, 1999, the
interest rate on the Securities will be increased by 0.5% per annum until the
Exchange Offer is consummated or the Shelf Registration Statement is declared
effective by the SEC; provided that such interest rate shall not be increased
pursuant to this Section 2(d) if the Company and the Guarantor are required to
file the Shelf Registration Statement solely as a result of matters referred to
in clause (iii) of the first sentence of Section 2(b) hereof and the Company and
the Guarantor shall not have received the opinion of counsel referred to in such
clause (iii) upon or prior to the consummation of the Exchange Offer.

                (e)     Without limiting the remedies available to the Placement
Agents and the Holders, the Company acknowledges that any failure by the Company
to comply with its 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 Company's obligations under Section 2(a)
and Section 2(b) hereof.

                3.      Registration Procedures.

                In connection with the obligations of the Company with respect
to the Registration Statements pursuant to Section 2(a) and Section 2(b) hereof,
the Company 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 Company 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 its best efforts to cause such Registration Statement
to become effective and remain effective in accordance with Section 2 hereof;




                                       7
   9

                (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 the
extent required, 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 Company consents 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 its best efforts to register or qualify the
Registrable Securities under all applicable state securities or "blue sky" laws
of such jurisdictions as may be required in connection with the Exchange Offer
and, in connection with the Shelf Registration, as any Shelf Holder 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 Shelf Holder to consummate the disposition
in each such jurisdiction of such Registrable Securities owned by such Shelf
Holder; provided, however, that the Company 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 Shelf
Holder, 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 Shelf 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 Shelf Registration Statement and Prospectus or for additional
information after the Shelf 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 Shelf Registration Statement or the initiation
of any proceedings for that purpose, (iv) if, between the effective date of a
Shelf Registration Statement and the closing of any sale of Registrable
Securities covered thereby, the representations and warranties of the Company
contained in any underwriting agreement, securities sales agreement or other
similar agreement, if any, relating to the offering




                                       8

cease to be true and correct in all material respects or if the Company receives
any notification with respect to the suspension of the qualification of the
Registrable Securities for sale in any jurisdiction or the initiation of any
proceeding for such purpose, (v) of the happening of any event during the period
a Shelf Registration Statement is effective which makes any statement made in
such Shelf Registration Statement or the related Prospectus untrue in any
material respect or which requires the making of any changes in such Shelf
Registration Statement or Prospectus in order to make the statements therein not
misleading and (vi) of any determination by the Company that a post-effective
amendment to a Shelf 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
Shelf Holder, 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
Shelf Holders 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 Shelf Holders may reasonably request at least two business days 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 its 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 Company agrees to notify the
Shelf 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 Company has amended or supplemented the Prospectus to
correct such misstatement or omission;

                (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 Shelf Holders and one counsel to be chosen by the Majority Shelf
Holders) and make such of the representatives of the Company as shall be
reasonably requested by the




                                       9
   11

Placement Agents or their counsel (and, in the case of a Shelf Registration
Statement, the Shelf Holders or their counsel chosen as provided in this
paragraph) 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 Shelf Holders and their counsel
chosen as provided in this paragraph) 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 Shelf Holders or their counsel
chosen as provided in this paragraph) shall reasonably object.

                (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 its best efforts to cause the
Trustee to execute, all documents as may be required to effect such changes and
all other forms and documents required to be filed with the SEC to enable the
Indenture to be so qualified in a timely manner;

                (m)     in the case of a Shelf Registration, make available for
inspection by a representative of the Shelf Holders designated by the Majority
Shelf Holders, any Underwriter participating in any Underwritten Offering
pursuant to such Shelf Registration Statement, and attorneys and accountants
designated by the Majority Shelf Holders, at reasonable times and in a
reasonable manner, all financial and other records, pertinent documents and
properties of the Company, and cause the respective officers, directors and
employees of the Company to supply all information reasonably requested by any
such representative, Underwriter, attorney or accountant in connection with a
Shelf Registration Statement;

                (n)     in the case of a Shelf Registration, use its best
efforts to cause all Registrable Securities to be listed on any securities
exchange or any automated quotation system on which similar securities issued by
the Company are then listed if requested by the Majority Shelf Holders, to the
extent such Registrable Securities satisfy applicable listing requirements;

                (o)     use its best efforts to cause the Exchange Securities or
Registrable Securities, as the case may be, to be rated by two nationally
recognized statistical rating organizations (as such term is defined in Rule
436(g)(2) under the 1933 Act);

                (p)     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-




                                       10
   12

effective amendment as promptly as practicable after the Company has received
notification of the matters to be incorporated in such filing; and

                (q)     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, pursuant to an
Underwritten Offering and in such connection, (i) to the extent possible, make
such representations and warranties to the Holders and any Underwriters of such
Registrable Securities with respect to the business of the Company and its
subsidiaries, the Registration Statement, Prospectus and documents incorporated
by reference or deemed incorporated by reference, if any, in each case, in form,
substance and scope as are customarily made by issuers to underwriters in
underwritten offerings and confirm the same if and when requested, (ii) obtain
opinions of counsel to the Company (which counsel and opinions, in form, scope
and substance, shall be reasonably satisfactory to a representative designated
by the Majority Shelf 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 Company (and, if necessary, any other
certified public accountant of any subsidiary of the Company, or of any business
acquired by the Company 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 Majority
Shelf Holders or the Underwriters, and which are customarily delivered in
underwritten offerings, to evidence the continued validity of the
representations and warranties of the Company 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 Company may
require each Shelf Holder to furnish to the Company such information regarding
the Shelf Holder and the proposed distribution by such Shelf Holder as the
Company 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 Company 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 Shelf Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof, and, if
so directed by the Company, such Shelf Holder will deliver to the Company (at
its expense) all copies in its possession, other than permanent file copies then
in such Shelf Holder's possession, of the Prospectus covering such Registrable
Securities current at the time of receipt of such notice. If the Company shall
give any such notice to suspend the disposition of Registrable Securities
pursuant to a Shelf Registration Statement, the Company shall extend the period
during which




                                       11
   13

the Shelf Registration Statement shall be maintained effective pursuant to this
Agreement by the number of days during the period from and including the date of
the giving of such notice to and including the date when the Shelf Holders shall
have received copies of the supplemented or amended Prospectus necessary to
resume such dispositions.

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

                4.      Participation of Broker-Dealers in Exchange Offer.

                (a)     The staff of the SEC has taken the position that any
broker-dealer that receives Exchange Securities for its own account in the
Exchange Offer in exchange for Securities that were acquired by 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 Company understands 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 Company agrees 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 of the
SEC recited in Section 4(a) above; provided that:

                (i)     the Company 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 and Participating
        Broker-Dealers shall not be authorized by the Company 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




                                       12
   14

        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 Company by the Placement Agents or with the
        reasonable request in writing to the Company by one or more
        broker-dealers who certify to the Placement Agents and the Company 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 Company 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, in which case it shall be designated by
        Participating Broker-Dealers holding a majority in principal amount of
        all Securities held by Participating Broker-Dealers (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.

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

                5.      Indemnification and Contribution.

                (a)     The Company and the Guarantor, jointly and severally,
agree 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 any Placement
Agent, 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 Company or the
Guarantor 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 Company in writing through Morgan Stanley
& Co. Incorporated or any Holder expressly for use therein, provided, however,
that the foregoing indemnity agreement with respect to any preliminary
Prospectus shall not inure to the benefit of any Holder




                                       13
   15

from whom the person asserting any such losses, claims, damages or liabilities
purchased Securities, or any person controlling such Holder, if a copy of the
final Prospectus (as then amended or supplemented if the Company 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 Securities
to such person, and if the final Prospectus (as so amended or supplemented)
would have cured the defect giving rise to such losses, claims, damages or
liabilities, unless such failure is the result of the Company to provide such
Holder with as many copies of such final Prospectus as such Holder may
reasonably request. In connection with any Underwritten Offering permitted by
Section 3, the Company and the Guarantor, jointly and severally, 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 Company, the Guarantor, each Placement Agent and
the other selling Holders, and each of their respective directors, officers of
the Company or the Guarantor who sign the Registration Statement and each
Person, if any, who controls the Company, the Guarantor, 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 Company to the Placement Agents and the Holders, but only with reference to
information relating to such Holder furnished to the Company 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 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.
The Company may assume at its sole expense the defense of any such litigation or
proceeding; such defense shall be conducted by counsel reasonably satisfactory
to such indemnified person and the Company shall pay the fees and disbursements
of such counsel related to such proceeding. Notwithstanding the foregoing, in
any such proceeding, any indemnified party shall have the right to retain its
own counsel and assume its own defense in such proceeding, 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




                                       14
   16

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 reasonably satisfactory to the
indemnifying party) 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 Company, its directors,
its officers who sign the Registration Statement and each Person, if any, who
controls the Company 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 Company. 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 45 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 such
indemnifying party and such indemnified party 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 such indemnifying party or such indemnified
party 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




                                       15
   17

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 parties hereto 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 any Placement Agent, any Holder or any Person controlling any Placement Agent
or any Holder, or by or on behalf of the Company, its officers or directors or
any Person controlling the Company, (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. The Company has not 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 Company's 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 Company has obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or 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.




                                       16
   18

                (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 Company 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 in the Placement Agreement; and (ii) if to the Company,
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 Company with respect to any failure by a Holder to comply
with, or any breach by any Holder of, any of the obligations of such Holder
under this Agreement.

                (e)     Purchases and Sales of Securities. The Company shall
not, and shall use its best efforts to cause its 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 Company, 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.
