          2.   Registration Under the 1933 Act.
               -------------------------------

          (a)  To the extent not prohibited by any applicable law or applicable
interpretation of the Staff of the SEC, the Company and the Guarantors shall use
their best efforts to cause to be filed an Exchange Offer Registration Statement
covering the offer by the Company and the Guarantors to the Holders to exchange
all of the Registrable Securities for Exchange Securities and to have such
Registration Statement remain effective until the closing of the Exchange Offer.
The Company and the Guarantors shall commence the Exchange Offer promptly after
the Exchange Offer Registration Statement has been declared effective by the SEC
and use its best efforts to have the Exchange Offer consummated not later than
60 days after such effective date.  The Company and the Guarantors shall
commence the Exchange Offer by mailing the related exchange offer Prospectus and
accompanying documents to each Holder stating, in addition to such other
disclosures as are required by applicable law:

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

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

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

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

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

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


                                       6

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

          (ii) deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Securities or portions thereof so accepted for
     exchange by the Company and issue, and cause the Trustee to promptly
     authenticate and mail to each Holder, an Exchange Security equal in
     principal amount to the principal amount of the Registrable Securities
     surrendered by such Holder.

The Company and the Guarantors shall use their best efforts to complete the
Exchange Offer as provided above and shall comply with the applicable
requirements of the 1933 Act, the 1934 Act and other applicable laws and
regulations in connection with the Exchange Offer.  The Exchange Offer shall not
be subject to any conditions, other than that the Exchange Offer does not
violate applicable law or any applicable interpretation of the Staff of the SEC.
The Company shall inform the Placement Agent of the names and addresses of the
Holders to whom the Exchange Offer is made, and the Placement Agent 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 and the Guarantors determine
that the Exchange Offer Registration provided for in Section 2(a) above is not
available or may not be consummated as soon as practicable after the last
Exchange Date because it would violate applicable law or the applicable
interpretations of the Staff of the SEC, (ii) the Exchange Offer is not for any
other reason consummated by January 23, 2000 or (iii) the Exchange Offer has
been completed and in the opinion of counsel for the Placement Agent a
Registration Statement must be filed and a Prospectus must be delivered by the
Placement Agent in connection with any offering or sale of Registrable
Securities, the Company and the Guarantors shall use their best efforts to cause
to be filed as soon as practicable after such determination, date or notice of
such opinion of counsel is given to the 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 Guarantors 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
Guarantors shall use their best efforts to file and have declared effective by
the SEC 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 Agent after completion
of the Exchange Offer.  The Company and the Guarantors agree to use their 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


                                       7

Statement. The Company and the Guarantors further agree to supplement or amend
the Shelf Registration Statement if required by the rules, regulations or
instructions applicable to the registration form used by the 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
Holder with respect to information relating to such 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 and the Guarantors agree to furnish to the Holders of Registrable
Securities copies of any such supplement or amendment promptly after its being
used or filed with the SEC.

          (c) The Company and the Guarantors shall pay all Registration Expenses
in connection with the registration pursuant to Section 2(a) or 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.  As provided for in the Indenture, in
the event the Exchange Offer is not consummated and the Shelf Registration
Statement is not declared effective on or prior to January 23, 2000, the annual
interest rate on the Securities will be increased by .5% until the Exchange
Offer is consummated or the Shelf Registration Statement is declared effective
by the SEC.

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

          3.   Registration Procedures.

          In connection with the obligations of the Company and the Guarantors
with respect to the Registration Statements pursuant to Section 2(a) and Section
2(b) hereof, the Company and the Guarantors shall as promptly as practicable:

     so supplemented, to be filed pursuant to Rule 424 under the 1933 Act; to
     keep each Prospectus current during the period described under Section 4(3)
     and Rule 174 under the 1933 Act that is applicable to transactions by

     Securities;

          (c) in the case of a Shelf Registration, furnish to each Holder of

     may reasonably request, in order to facilitate the public sale or other
     disposition of the Registrable Securities; and the Company and the
     Guarantors consent to the use of such Prospectus and any amendment or
     supplement thereto in accordance with applicable law by each of the selling
     Holders of Registrable Securities and any such Underwriters in connection
     with the offering and sale of the Registrable Securities covered by and in
     the manner described in such Prospectus or any amendment or supplement
     thereto in accordance with applicable law;

          (d) use their best efforts to register or qualify the Registrable
     Securities under all applicable state securities or "blue sky" laws of such

     by the SEC, to cooperate with such Holders in connection with any filings
     required to be made with the National Association of Securities Dealers,
     Inc. and do any and all other acts and things which may be reasonably
     necessary or advisable to enable such Holder to consummate the disposition
     in each such jurisdiction of such Registrable Securities owned by such
     Holder; provided, however, that neither the Company nor any Guarantor shall
             --------  -------
     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

     Placement Agent promptly and, if requested by any such Holder or counsel,

     Registrable Securities for sale in any jurisdiction or the initiation of
     any proceeding for such purpose, (v) of the happening of any event during

     in such Registration Statement or Prospectus in order to make the
     statements therein not misleading and (vi) of any determination by the
     Company or any Guarantor that a post-effective amendment to a Registration

     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 and the Guarantors agree to notify the
     Holders to suspend use of the Prospectus as promptly as practicable after
     the occurrence of such an event, and the Holders hereby agree to suspend
     use of the Prospectus until the Company and the Guarantors have 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 Agent and its counsel and make such of the
     representatives of the Company and the Guarantors as shall be reasonably
     requested by the Placement Agent or its counsel available for discussion of
     such document, and shall not at any time file or make any amendment to the
     Registration Statement, any Prospectus or any amendment of or supplement to
     a Registration Statement or a Prospectus, of which the Placement Agent and
     its counsel shall not have previously been advised and furnished a copy or
     to which the Placement Agent or its counsel, acting on behalf of both the
     Placement Agent and the Holders, 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;


                                       11

          (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 Holders of the Registrable Securities, any
     Underwriter participating in any disposition pursuant to such Shelf
     Registration Statement, and attorneys and accountants designated by the
     Holders, at reasonable times and in a reasonable manner, all financial and
     other records, pertinent documents and properties of the Company and the
     Guarantors, and cause the respective officers, directors and employees of
     the Company and the Guarantors to supply all information reasonably
     requested by any such representative, Underwriter, attorney or accountant
     in connection with a Shelf Registration Statement; provided, however, that
     any information that is designated in writing by the Company, in good
     faith, as confidential at the time of delivery of such information shall be
     kept confidential by the Holders or any such Underwriter, attorney,
     accountant or other agent, unless such disclosure is made in connection
     with a court proceeding or required by law, or such information becomes
     available to the public generally or through a third party without an
     accompanying obligation of confidentiality.

          (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 or any Guarantor are then listed if requested by the Majority
     Holders, to the extent such Registrable Securities satisfy applicable
     listing requirements;

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

          (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


                                       12

     Prospectus supplement or such post-effective amendment as soon as the
     Company has received notification of the matt ers to be incorporated in
     such filing;

          (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, 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 material subsidiaries, the Registration Statement,
     Prospectus and documents incorporated by reference or deemed incorporated
     by reference, if any, in each case, in form, substance and scope as are
     customarily made by issuers to underwriters in underwritten offerings and
     confirm the same if and when requested, (ii) obtain opinions of counsel to
     the Company and the Guarantors (which counsel and opinions, in form, scope
     and substance, shall be reasonably satisfactory to the Holders and such
     Underwriters and their respective counsel) addressed to each selling Holder
     and Underwriter of Registrable Securities, covering the matters customarily
     covered in opinions requested in underwritten offerings, (iii) obtain "cold
     comfort" letters from the independent certified public accountants of the
     Company and the Guarantors (and, if necessary, any other certified public
     accountant of any subsidiary of the Company or any Guarantor, or of any
     business acquired by the Company or any Guarantor for which financial
     statements and financial data are or are required to be included in the
     Registration Statement) addressed to each selling Holder and Underwriter of
     Registrable Securities, such letters to be in customary form and covering
     matters of the type customarily covered in "cold comfort" letters in
     connection with underwritten offerings, and (iv) deliver such documents and
     certificates as may be reasonably requested by the Holders of a majority in
     principal amount of the Registrable Securities being sold or the
     Underwriters, and which are customarily delivered in underwritten
     offerings, to evidence the continued validity of the representations and
     warranties of the Company and the Guarantors made pursuant to clause (i)
     above and to evidence compliance with any customary conditions contained in
     an underwriting agreement; and

          (r) in the case of a Shelf Registration Statement, in the event that,
     in the reasonable judgment of the Company, it is advisable to suspend use
     of the Prospectus for a discrete period of time due to pending material
     corporate developments or similar material events that have not yet been
     publicly disclosed and as to which the Company reasonably believes public
     disclosure will be prejudicial to the Company, the Company shall deliver a
     certificate in writing, signed by its Chief Executive Officer or Chief
     Financial Officer, to the Holders to the effect of the foregoing and, upon
     receipt of such certificate, each such Holder shall not commence selling
     its Registrable Securities


                                       13

     pursuant to such Prospectus until such Holder's receipt of copies of the
     supplemented or amended Prospectus, or until it is advised in writing by
     the Company that the Prospectus may be used, and has received copies of any
     additional or supplemental filings that are incorporated or deemed
     incorporated by reference in such Prospectus. The Company will use its best
     efforts to ensure that the use of the Prospectus may be resumed, as
     promptly as is practicable and as soon as the earlier of (x) public
     disclosure of such pending material corporate development or similar
     material event or (y) in the reasonable judgment of the Company, public
     disclosure of such pending material corporate development or similar
     material event would not be prejudicial to the Company.

          In the case of a Shelf Registration Statement, the Company and the
Guarantors may require each Holder of Registrable Securities to furnish to the
Company and the Guarantors such information regarding the Holder and the
proposed distribution by such Holder of such Registrable Securities as the
Company and the Guarantors may from time to time reasonably request in writing.
No Holder of Registrable Securities will be entitled to have such Registrable
Securities included in a Shelf Registration Statement if such Holder does not
furnish the information required by the Company and the Guarantors.

          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company and the Guarantors of the
happening of any event of the kind described in Section 3(e)(v) or Section 3(r)
hereof, such Holder will forthwith discontinue disposition of Registrable
Securities pursuant to a Registration Statement until such Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
3(i) hereof, and, if so directed by the Company and the Guarantors, such Holder
will deliver to the Company and the Guarantors (at its expense) all copies, if
any, in its possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities current at
the time of receipt of such notice.  The Company and the Guarantors may give any
such notice only twice during any 365 day period and any such suspensions may
not exceed, in the aggregate, 60 days, regardless of whether consecutive, during
any 365 day period.

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

          4.   Participation of Broker-Dealers in Exchange Offer.
               --------------------------------------------------


                                       14

          (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 and the Guarantors understand that it is the Staff's
position that if the Prospectus contained in the Exchange Offer Registration
Statement includes a plan of distribution containing a statement to the above
effect and the means by which Participating Broker-Dealers may resell the
Exchange Securities, without naming the Participating Broker-Dealers or
specifying the amount of Exchange Securities owned by them, such Prospectus may
be delivered by Participating Broker-Dealers to satisfy their prospectus
delivery obligation under the 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 and the Guarantors agree that the provisions of this
Agreement as they relate to a Shelf Registration shall also apply to an Exchange
Offer Registration to the extent, and with such reasonable modifications thereto
as may be, reasonably requested by the Placement Agent or by one or more
Participating Broker-Dealers, in each case as provided in clause (ii) below, in
order to expedite or facilitate the disposition of any Exchange Securities by
Participating Broker-Dealers consistent with the positions of the Staff recited
in Section 4(a) above; provided that:
                       --------

          (i)  the Company and the Guarantors shall not be required to amend or
     supplement the Prospectus contained in the Exchange Offer Registration
     Statement, as would otherwise be contemplated by Section 3(i), for a period
     exceeding 180 days after the last Exchange Date (as such period may be
     extended pursuant to the penultimate paragraph of Section 3 of this
     Agreement) and Participating Broker-Dealers shall not be authorized by the
     Company and the Guarantors to deliver and shall not deliver such Prospectus
     after such period in connection with the resales contemplated by this
     Section 4; and

          (ii) the application of the Shelf Registration procedures set forth in
     Section 3 of this Agreement to an Exchange Offer Registration, to the
     extent not required by the positions of the Staff of the SEC or the 1933
     Act and the rules and regulations thereunder, will be in conformity with
     the reasonable request to the Company and the Guarantors by the Placement
     Agent or with the reasonable request in writing to the Company and the
     Guarantors by one or more broker-dealers who certify to the Placement Agent
     and the Company and the Guarantors in writing that they anticipate


                                       15

     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 and
     the Guarantors shall be obligated (x) to deal only with one entity
     representing the Participating Broker-Dealers, which shall be Morgan
     Stanley & Co. Incorporated unless it elects not to act as such
     representative, (y) to pay the fees and expenses of only one counsel
     representing the Participating Broker-Dealers, which shall be counsel to
     the Placement Agent 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 Agent shall have no liability to the Company, any
Guarantor or any Holder with respect to any request that it may make pursuant to
Section 4(b) above.

          5.  Indemnification and Contribution.
              --------------------------------


                                       16

          (a) Each of the Company and the Guarantors agrees jointly and
severally to indemnify and hold harmless the Placement Agent, each Holder and
each Person, if any, who controls the 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, the Placement Agent or any
Holder, from and against all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred by the
Placement 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 and the
Guarantors 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 Agent or any Holder furnished to the Company or the Guarantors in
writing by Morgan Stanley & Co. Incorporated or any selling Holder expressly for
use therein; provided that the foregoing indemnity with respect to any
preliminary Prospectus shall not inure to the benefit of any Holder from whom
the person asserting any such losses, claims, damages or liabilities purchased
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 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 loss, claim,
damage or liability.  In connection with any Underwritten Offering permitted by
Section 3, the Company and the Guarantors 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 and the Guarantors, the Placement Agent and the other
selling Holders, and each of their respective directors, officers who sign the
Registration Statement and each Person, if any, who controls the Company, the
Guarantors, the Placement Agent and any other selling Holder within the meaning
of either Section 15 of the 1933 Act or Section 20 of the


                                       17

1934 Act to the same extent as the foregoing indemnity from the Company and the
Guarantors to the Placement Agent and the Holders, but only with reference to
information relating to such Holder furnished to the Company and the Guarantors
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.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel and the
indemnifying party has agreed to pay the fees and expenses of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them.  It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (a) the fees and expenses of
more than one separate firm (in addition to any local counsel) for the Placement
Agent and all Persons, if any, who control the 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, the Guarantors, their directors, their officers who
sign the Registration Statement and each Person, if any, who controls the
Company or the Guarantors 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 upon written request and presentation of
invoices.  In such case involving the Placement Agent and Persons who control
the Placement Agent, 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


                                       18

party shall have requested an indemnifying party to reimburse the indemnified
party for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and (ii) such indemnifying party
shall not have reimbursed the indemnified party for such fees and expenses of
counsel in accordance with such request prior to the date of such settlement.
Notwithstanding the immediately preceding 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, an indemnifying party shall
not be liable for any settlement of the nature contemplated by this Section 8(c)
effected without its consent if such indemnifying party (i) reimburses such
indemnified party in accordance with such request to the extent that it in good
faith considers such request to be reasonable and (ii) provides written notice
to the indemnified party substantiating the unpaid balance as unreasonable, in
each case 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 referred to therein, then
each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the indemnifying party or parties on the one hand and of the indemnified
party or parties on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations.  The relative fault of the
Company, the Guarantors and the Holders shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Guarantors or by the Holders and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Holders' respective
obligations to contribute pursuant to this Section 5(d) are several in
proportion to the respective principal amount of Registrable Securities of such
Holder that were registered pursuant to a Registration Statement.

          (e) The Company, the Guarantors and each Holder agree that it would
not be just or equitable if contribution pursuant to this Section 5 were
determined by pro rata
              --- ----


                                       19

allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages
and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 5, no Holder shall be required to indemnify or contribute any amount in
excess of the amount by which the total price at which Registrable Securities
were sold by such Holder exceeds the amount of any damages that such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

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

          6.  Miscellaneous.
              -------------

          (a) No Inconsistent Agreements.  Neither the Company nor the
              --------------------------
Guarantors have 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 or the Guarantors' 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 and the Guarantors have obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or consent; provided, however, that no amendment,
                               --------  -------
modification, supplement, waiver or consent to any departure from the provisions
of Section 5


                                       20

hereof shall be effective as against any Holder of Registrable Securities unless
consented to in writing by such Holder.

          (c) Notices.  All notices and other communications provided for or
              -------
permitted hereunder shall be made in writing by hand-delivery, registered first-
class mail, telex, telecopier, or any courier guaranteeing overnight delivery
(i) if to a Holder, at the most current address given by such Holder to the
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 Agent,
the address set forth in the Placement Agreement; and (ii) if to the Company or
the Guarantors, 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
