<PAGE>
                                      5

          (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
shall:

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     tendered and not validly withdrawn pursuant to the Exchange Offer; and

          (ii)   deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Securities or portions thereof so accepted for
     exchange by the 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 reasonable 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 

<PAGE>
                                      6

the Exchange Offer does not violate applicable law or any applicable 
interpretation of the Staff of the SEC. The Company shall inform the 
Placement Agents of the names and addresses of the Holders to whom the 
Exchange Offer is made, and the Placement Agents shall have the right, 
subject to applicable law, to contact such Holders and otherwise facilitate 
the tender of Registrable Securities in the Exchange Offer.  Each Holder who 
participates in the Exchange Offer will be required to represent that any 
Exchange Securities received by it will be acquired in the ordinary course of 
its business, that at the time of the consummation of the Exchange Offer such 
Holder will have no arrangement or understanding with any person to 
participate in the distribution of the Exchange Securities, and that such 
Holder is not an affiliate of the Company within the meaning of Rule 405 
promulgated under the 1933 Act or if it is such an affiliate, that it will 
comply with the registration and prospectus delivery requirements of the 1933 
Act, to the extent applicable.

          (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
June 21, 1999 or (iii) any Holder of Registrable Securities shall provide the
Company prior to the 20th day following the consummation of the Exchange Offer
an opinion of counsel that (A) such Holder is prohibited by applicable law or
applicable interpretation of the Staff of the SEC from participating in the
Exchange Offer, or (B) such Holder may not resell the 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, the Company and the
Guarantors shall use their reasonable 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 is 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 reasonable
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 and the Guarantors
agree to use their reasonable 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 and the Guarantors further agree to supplement or amend
the Shelf Registration 

<PAGE>
                                      7

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 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.

          (e)    Without limiting the remedies available to the Placement
Agents and the Holders, the Company and the Guarantors acknowledge that any
failure by the Company and the Guarantors to comply with their obligations under
Section 2(a) and Section 2(b) hereof may result in material irreparable injury
to the Placement Agents or the Holders for which there is no adequate remedy at
law, that it will not be possible to measure damages for such injuries precisely
and that, in the event of any such failure, the Placement Agents or any Holder
may obtain such relief as may be required to specifically enforce the
obligations of the Company and the Guarantors under Section 2(a) and
Section 2(b) hereof.

          (f)     As provided for in the Indenture, in the event the Exchange
Offer is not consummated and the Shelf Registration Statement is not declared
effective (or not deemed to have become effective pursuant to clause (d) above)
on or prior to June 21, 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.

     prospectus supplement and, as so supplemented, to be filed pursuant to 
     Rule 424 under the 1933 Act; to keep each Prospectus current during the

                                      9

     declared effective by the SEC, to cooperate with such Holders in connection
     with any filings required to be made with the National Association of 
     Securities Dealers, Inc. and do any and all other acts and things which may
     be reasonably necessary or advisable to enable such Holder to consummate 
     the disposition in each such jurisdiction of such Registrable Securities 
     owned by such Holder; PROVIDED, HOWEVER, that 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

     and the closing of any sale of Registrable Securities covered thereby, the
     representations and warranties of the Company or any Guarantor contained in
     any underwriting agreement, securities sales agreement or other similar
     agreement, if any, relating to the offering cease to be true and correct in
     all material respects or if the Company or any Guarantor 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

     therein by reference or exhibits thereto, unless requested);

          (h)    in the case of a Shelf Registration, cooperate with the
     selling Holders of Registrable Securities to facilitate the timely
     preparation and delivery of certificates representing Registrable
     Securities to be sold and not bearing any restrictive legends and enable
     such Registrable Securities to be in such denominations (consistent with
     the provisions of the Indenture) and registered in such names as the
     selling Holders may reasonably request at least one business day prior to
     the closing of any sale of Registrable Securities;

          (i)    in the case of a Shelf Registration, upon the occurrence of
     any event contemplated by Section 3(e)(v) hereof, use their reasonable 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 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 Agents and their counsel (and, in the case of a
     Shelf Registration Statement, the Holders and their counsel) and make such
     of the representatives of the Company and the Guarantors as shall be
     reasonably requested by the Placement Agents or their counsel (and, in the
     case of a Shelf Registration Statement, the Holders or their counsel)
     available for discussion of such document, and shall not at any time file
     or make any amendment to the Registration Statement, any Prospectus or any
     amendment of or supplement to a Registration Statement or a Prospectus or
     any document which is to be incorporated by reference into a Registration
     Statement or a Prospectus, of which the Placement Agents and their counsel
     (and, in the case of a Shelf Registration Statement, the Holders and their
     counsel) shall not have previously been advised and furnished a copy or to
     which the 

<PAGE>
                                      11

     Placement Agents or their counsel (and, in the case of a Shelf Registration
     Statement, the Holders or their counsel) 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 reasonable
     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 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; 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 such
     representative, any Holders or any such Underwriter, attorney or
     accountant, 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)    use its reasonable 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), if such Exchange Securities
     or Registrable Securities are not already so rated;

          (o)    if 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 and the terms of such sale of Registrable Securities as is
     required by the applicable rules and regulations of the SEC  and (ii) make
     all required filings of such Prospectus supplement or such 

<PAGE>
                                      12

     post-effective amendment as soon as 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, 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, the Guarantors and their subsidiaries, the Registration
     Statement, Prospectus and documents incorporated by reference or deemed
     incorporated by reference, if any, in each case, in form, substance and
     scope as are customarily made by issuers to underwriters in underwritten
     offerings and confirm the same if and when requested, (ii) obtain opinions
     of counsel to the 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. 

          In the case of a Shelf Registration Statement, the Company or 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 or the Guarantors 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 

<PAGE>
                                      13

Section 3(e)(v) hereof, such Holder will forthwith discontinue disposition of 
Registrable Securities pursuant to a Registration Statement until such 
Holder's receipt of the copies of the supplemented or amended Prospectus 
contemplated by Section 3(i) hereof, and, if so directed by the Company, such 
Holder will deliver to the Company (at its expense) all copies in its 
possession, other than permanent file copies then in such Holder's 
possession, of the Prospectus covering such Registrable Securities current at 
the time of receipt of such notice.  If the Company shall give any such 
notice to suspend the disposition of Registrable Securities pursuant to a 
Registration Statement, the Company shall extend the period during which the 
Registration Statement shall be maintained effective pursuant to this 
Agreement by the number of days during the period from and including the date 
of the giving of such notice to and including the date when the Holders shall 
have received copies of the supplemented or amended Prospectus necessary to 
resume such dispositions. Any such suspensions may not exceed 60 days in the 
aggregate 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.

          (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 

<PAGE>
                                      14

extent, and with such reasonable modifications thereto as may be, reasonably 
requested by the Placement Agents or by one or more Participating 
Broker-Dealers, in each case as provided in clause (ii) below, in order to 
expedite or facilitate the disposition of any Exchange Securities by 
Participating Broker-Dealers consistent with the positions of the Staff 
recited in Section 4(a) above; PROVIDED that:

          (i)    the 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 or 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 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 and the Guarantors shall be obligated 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.

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

          (d)    Each Holder who wishes to exchange Securities for Exchange
Securities in the Exchange Offer and who is not a Broker-Dealer shall represent
that it is not engaged in, and does not intend to engage in, the distribution of
the Exchange Securities.

          (e)    Each Holder who wishes to exchange Securities for Exchange
Securities in the Exchange Offer and who is a Broker-Dealer that will receive
Exchange Securities for its own account in exchange for Securities that were
acquired as a result of market-making activities or other trading activities
shall acknowledge that it will deliver a prospectus in connection with any
resale of such Exchange Securities.

          5.     INDEMNIFICATION AND CONTRIBUTION.

          (a)    Each of the Company and the Guarantors, jointly and severally,
agrees to indemnify and hold harmless the Placement Agents, each Holder and each
Person, if any, who controls any Placement Agent or any Holder within the
meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or
is under common control with, or is controlled by, any Placement Agent or any
Holder, from and against all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred by the
Placement 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 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 by Morgan Stanley & Co. Incorporated or any
selling Holder expressly for use therein PROVIDED, HOWEVER, that, in the case of
a Shelf Registration, the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of any indemnified party
from whom the person asserting any such losses, claims, damages or liabilities
purchased Securities or of any person controlling such indemnified party, if a
copy of the final prospectus (as amended or supplemented if the Company shall
have furnished any amendments or supplements thereto) was provided to such
indemnified party by the Company but was not sent or given by or on behalf of
such indemnified party 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 amended or supplemented) would
have cured the defect giving rise to such losses, claims, damages or
liabilities.  In connection with any Underwritten Offering permitted by Section
3, each of 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.

<PAGE>
                                      16

          (b)    Each Holder agrees, severally and not jointly, to indemnify
and hold harmless the Company, the Guarantors, the Placement Agents and the
other selling Holders, and each of their respective directors, officers who sign
the Registration Statement and each Person, if any, who controls the Company,
any 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 and the Guarantors
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.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  It is understood that the indemnifying party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for (a) the fees and expenses of more than one separate
firm (in addition to any local counsel) for the Placement Agents and all
Persons, if any, who control any Placement Agent within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Company, the Guarantors and their directors and officers who sign the
Registration Statement and each Person, if any, who controls the Company or any
Guarantor 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 

<PAGE>
                                      17

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 60 days after receipt by such indemnifying party of 
the aforesaid request, (ii) the indemnifying party has been provided with a 
copy of the proposed terms of the settlement at least 30 days prior to such 
settlement being entered into, and (iii) 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; 
provided that the indemnifying party shall not be required to reimburse such 
amounts pursuant to a settlement effected without its consent pursuant to 
this sentence during the period that such indemnifying party is contesting 
such reimbursement obligation in good faith by appropriate proceedings.  No 
indemnifying party shall, without the prior written consent of the 
indemnified party, effect any settlement of any pending or threatened 
proceeding in respect of which such indemnified party is or could have been a 
party and indemnity could have been sought hereunder by such indemnified 
party, unless such settlement includes an unconditional release of such 
indemnified party from all liability on claims that are the subject matter of 
such proceeding.

          (d)    If the indemnification provided for in paragraph (a) or
paragraph (b) of this Section 5 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the indemnifying party or parties on the one hand and of the indemnified
party or parties on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations.  The relative fault of the
Company and 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 and 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.  

<PAGE>
                                      18

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

          The indemnity and contribution provisions contained in this Section 5
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
the Placement Agents, any Holder or any Person controlling any Placement Agent
or any Holder, or by or on behalf of the Company, the Guarantors, their officers
or directors or any Person controlling the Company or any Guarantor,
(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 and the Guarantors
have 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 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, 

<PAGE>
                                      19

modification, supplement, waiver or consent; PROVIDED, HOWEVER, that no 
amendment, modification, supplement, waiver or consent to any departure from 
the provisions of Section 5 hereof shall be effective as against any Holder 
of Registrable Securities unless consented to in writing by such Holder.

          (c)    NOTICES.  All notices and other communications provided for 
or permitted hereunder shall be made in writing by hand-delivery, registered 
first-class mail, telex, telecopier, or any courier guaranteeing overnight 
delivery (i) if to a Holder, at the most current address given by such Holder 
to the 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 and 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
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 or any Guarantor 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.

<PAGE>
                                      20

          (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 and the
Guarantors, on the one hand, and the Placement Agents, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder.

          (g)    COUNTERPARTS.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
