                     EXCHANGE REGISTRATION RIGHTS AGREEMENT
                     --------------------------------------


                                                                    May 10, 1995

CS First Boston Corporation
  As Representative of the Several Initial Purchasers
    Park Avenue Plaza
      New York, New York  10055

Ladies and Gentlemen:

     Cincinnati Milacron Inc., a Delaware corporation (the "Company"), proposes
to issue and sell to CS First Boston Corporation, BT Securities Corporation and
J.P. Morgan Securities Inc. (collectively, the "Initial Purchasers"), upon the
terms set forth in a purchase agreement of even date herewith (the "Purchase
Agreement"), $100,000,000 principal amount of its 7-7/8% Notes due 2000 (the
"Notes").  The Notes will be issued pursuant to an indenture, dated as of July
1, 1985, between the Company and BankAmerica National Trust Company (formerly
BankAmerica Trust Company of New York), as trustee (the "Trustee"), as such
indenture was supplemented by a first supplemental indenture, dated February 26,
1987, a second supplemental indenture, dated March 16, 1994 and a third
supplemental indenture dated May 17, 1995 (as so supplemented, the "Indenture").
As an inducement to the Initial Purchasers, the Company agrees with the Initial
Purchasers, for the benefit of the holders of the Notes (including, without
limitation, the Initial Purchasers, herein referred to as the "Holders"), as
follows:

     1.  Registered Exchange Offer.  The Company shall prepare and, not later
         -------------------------                                           
than 30 days after the date of original issue of the Notes, file with the
Securities and Exchange Commission (the "Commission") a registration statement
(the "Exchange Offer Registration Statement") on an appropriate form under the
Securities Act of 1933, as amended (the "Securities Act"), with respect to a
proposed offer (the "Registered Exchange Offer") to the Holders of the Notes to
issue and deliver to such Holders, in exchange for the Notes, a like principal
amount of

 
debt securities of the Company identical in all material respects to the Notes,
except for the transfer restrictions relating to the Notes (the "Exchange
Notes").  The Company shall use its best efforts to cause such Exchange Offer
Registration Statement to become effective under the Securities Act within 120
days after the date of original issue of the Notes.  Following the declaration
of the effectiveness of the Exchange Offer Registration Statement, the Company
shall promptly commence the Registered Exchange Offer, it being the objective of
such Registered Exchange Offer to enable each Holder of the Notes electing to
exchange the Notes for Exchange Notes and (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the
Exchange Notes in the ordinary course of such Holder's business and has no
arrangements with any person to participate in the distribution of the Exchange
Notes) to trade such Exchange Notes from and after their receipt without any
limitations or restrictions under the Securities Act and the securities laws of
the several states of the United States.  In connection with such Registered
Exchange Offer, the Company shall take such further action, including, without
limitation, appropriate filings under state securities laws, as may be necessary
to realize the foregoing objective subject to the proviso of Section 3(h).

     The Company shall include within the prospectus contained in the Exchange
Offer Registration Statement a section entitled "Plan of Distribution,"
reasonably acceptable to the Initial Purchasers, which shall contain a summary
statement of the positions taken or policies made by the staff of the Commission
with respect to the potential "underwriter" status of any broker-dealer that is
the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act
of 1934, as amended (the "Exchange Act")) of Exchange Notes received by such
broker-dealer in the Registered Exchange Offer (a "Participating Broker-
Dealer"), whether such positions or policies have been publicly disseminated by
the staff of the Commission or such positions or policies, in the reasonable
judgment of the Initial Purchasers based upon advice of counsel (which may be
in-house counsel), represent the prevailing views of the staff of the
Commission.  Such "Plan of Distribution" section shall also allow the use of the
prospectus by all persons subject to the prospectus delivery requirements of the
Securities Act, including Participating Broker-Dealers, and include a statement
describing the means by which Participating Broker-Dealers may resell the
Exchange Notes.

     The Company shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the prospectus
contained therein, in order to permit such prospectus to be lawfully delivered
by all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such

                                      -2-

 
requirements in order to resell the Exchange Notes; provided that such period
shall not exceed 180 days (or such longer period if extended pursuant to Section
3(j) below).

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Notes acquired by it as part of its initial distribution, the
Company upon the request of such Initial Purchaser shall simultaneously with the
delivery of the Exchange Notes pursuant to the Registered Exchange Offer issue
and deliver to such Initial Purchaser, in exchange (the "Private Exchange") for
the Notes held by such Initial Purchaser, a like principal amount of debt
securities of the Company identical in all material respects (including the
existence of restrictions on transfer under the Securities Act and the
securities laws of the several states of the United States) to the Notes (the
"Private Exchange Notes").  The Private Exchange Notes shall bear the same CUSIP
number as the Exchange Notes.

     In connection with the Registered Exchange Offer, the Company shall:

     (a)  mail to each Holder a copy of the prospectus forming part of the
Exchange Offer Registration Statement, together with an appropriate letter of
transmittal and related documents;

     (b)  keep the Registered Exchange Offer open for not less than 30 days
after the date notice thereof is mailed to the Holders (or longer if required by
applicable law);

     (c)  utilize the services of a depositary for the Registered Exchange Offer
with an address in the Borough of Manhattan, The City of New York, which may be
the Trustee or an affiliate of the Trustee;

     (d)  permit Holders to withdraw tendered Notes at any time prior to the
close of business, New York time, on the last business day on which the
Registered Exchange Offer shall remain open; and

     (e)  otherwise comply in all material respects with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (i) accept for exchange all the Notes validly tendered and not
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange; and

                                      -3-

 
          (ii) deliver to the Trustee for cancellation all the Notes so accepted
     for exchange, and cause the Trustee to authenticate and deliver promptly to
     each Holder of the Notes, Exchange Notes or Private Exchange Notes, as the
     case may be, equal in principal amount to the Notes of such Holder so
     accepted for exchange.

          The Exchange Notes and the Private Exchange Notes may be issued under
the Indenture (or a supplement thereto) or an indenture substantially similar to
the Indenture, which in any event will provide that the Exchange Notes will not
be subject to the transfer restrictions set forth in the Indenture and that the
Exchange Notes, the Private Exchange Notes and the Notes will vote and consent
together on all matters as one class and that none of the Exchange Notes, the
Private Exchange Notes or the Notes will have the right to vote or consent as a
class separate from one another on any matter.

          2.  Shelf Registration.  If, (i) because of any change in law or in
              ------------------                                             
currently prevailing interpretations of the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within
180 days of the date of this Agreement, (iii) any Initial Purchaser so requests
with respect to the Notes (or the Private Exchange Notes) not eligible to be
exchanged for Exchange Notes in the Registered Exchange Offer and held by it
following consummation of the Registered Exchange Offer or (iv) any Holder is
not eligible to participate in the Registered Exchange Offer or, in the case of
any Holder that participates in the Registered Exchange Offer or the Private
Exchange, such Holder does not receive freely tradeable Exchange Notes on the
date of the exchange, the Company shall take the following actions:

          (a)  The Company shall as promptly as practicable file with the
     Commission and thereafter shall use its best efforts to cause to be
     declared effective a registration statement (the "Shelf Registration
     Statement" and, together with the Exchange Offer Registration Statement, a
     "Registration Statement") on an appropriate form under the Securities Act
     relating to the offer and sale of the relevant Notes or, if applicable, the
     relevant Private Exchange Notes by the Holders thereof from time to time in
     accordance with the methods of distribution set forth in the Shelf
     Registration Statement and Rule 415 under the Securities Act (hereinafter,
     the "Shelf Registration").

          (b)  The Company shall use its best efforts to keep the Shelf
     Registration Statement continuously effective in order to permit the
     prospectus included therein to be lawfully delivered by the Holders of the
     relevant Notes or, if

                                      -4-

 
     applicable, the relevant Private Exchange Notes, for a period of three
     years (or for such longer period if extended pursuant to Section 3(j)
     below) from the date of its effectiveness or such shorter period that will
     terminate when all the Notes or, if applicable, the Private Exchange Notes
     covered by the Shelf Registration Statement have been sold pursuant
     thereto.

          (c)  Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause the Shelf Registration Statement and the
     related prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement, amendment or
     supplement, (i) to comply in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations of the
     Commission and (ii) not to contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

          3.  Registration Procedures.  In connection with any Shelf
              -----------------------                               
Registration contemplated by Section 2 hereof and, to the extent applicable, any

     any such filing, which shall not be unreasonably withheld.

          (b)  The Company shall give written notice to the Initial Purchasers,
     the Holders of the Notes and any Participating Broker-Dealer from whom the
     Company has received prior written notice that it will be a Participating
     Broker-Dealer in the Registered Exchange Offer:

                 (i) when the Registration Statement or any amendment thereto
          has been filed with the Commission and when the Registration Statement
          or any post-effective amendment thereto has become effective;

                 (ii) of any request by the Commission for amendments or
          supplements to the Registration Statement or the prospectus included
          therein or for additional information, provided that the contents need
                                                 --------                       
          only be disclosed to the Initial Purchasers and one counsel

                                      -5-

          any jurisdiction or the initiation or threatening of any proceeding
          for such purpose; and

                 (v) of the happening of any event that requires the Company to
          make changes in the Registration Statement or the prospectus in order
          to make the statements therein not misleading (which notice shall be
          accompanied by an instruction to suspend the use of the prospectus
          until the requisite changes have been made).

          (c)  The Company shall use its best efforts to prevent the issuance or
     obtain the withdrawal of any order suspending the effectiveness of the
     Registration Statement at the earliest possible time.

          (d)  The Company shall furnish to each Holder of the Notes or, if

     Statement and any amendment or supplement thereto as such

                                      -6-

 
     person may reasonably request.  The Company consents, subject to the
     provisions of this Agreement, to the use of the prospectus or any amendment
     or supplement thereto by each of the selling Holders of the Notes or, if
     applicable, the Private Exchange Notes in connection with the offering and
     sale of the Notes or, if applicable, the Private Exchange Notes covered by
     the prospectus, or any amendment or supplement thereto, included in the
     Shelf Registration Statement.

          (g)  The Company shall deliver to each Initial Purchaser, any

     the Registered Exchange Offer in connection with the offering and sale of
     the Exchange Notes covered by the prospectus, or any amendment or
     supplement thereto, included in such Exchange Offer Registration Statement.

          (h)  Prior to any public offering of the Notes or, if applicable, the
     Private Exchange Notes, pursuant to the Shelf Registration, the Company
     shall register or qualify or cooperate with the Holders of the Notes or, if
     applicable, the Private Exchange Notes, included therein and their
     respective counsel in connection with the registration or qualification of
     the Notes or, if applicable, the Private Exchange Notes, for offer and sale
     under the securities or "blue sky" laws of such states of the United States
     as any Holder of the Notes or the Private Exchange Notes reasonably
     requests in writing and do any and all other acts or things necessary or
     advisable to enable the offer and sale in such jurisdictions of the Notes
     or, if applicable, the Private Exchange Notes, covered by the Shelf
     Registration; provided that the Company shall not be required to (i)
                   --------

     service of process or to taxation in any jurisdiction where it is not then
     so subject.

     Shelf Registration.

          (j)  Upon the occurrence of any event contemplated by Section 3(b)(v)
     above, the Company shall promptly prepare a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus or file
     any other required document so that, as thereafter delivered to Holders of
     the Notes, the Exchange Notes or, if applicable, the Private Exchange
     Notes, as the case may be, the prospectus will not contain an untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein, in light of the circumstances under which
     they were made, not misleading.  If the Company notifies the Initial
     Purchasers, the Holders of the Notes and any known Participating Broker-
     Dealer in accordance with Section 3(b)(v) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,

     Participating Broker-Dealers shall suspend use of such prospectus, and the
     period of effectiveness of the Shelf Registration Statement provided for in
     Section 2(b) above and the Exchange Offer Registration Statement provided

     Participating Broker-Dealer shall have received such amended or
     supplemented prospectus pursuant to this Section 3(j).

          (k)  Not later than the effective date of the applicable Registration
     Statement, the Company will provide a CUSIP number for the Notes or
     Exchange Notes, as the case may be, and provide the applicable trustee with
     printed certificates for the Notes or Exchange Notes, as the case may be,
     in a form eligible for deposit with The Depository Trust Company.

          (l)  The Company will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the

     with Section 11(a) of the Securities Act) an earnings statement satisfying
     the provisions of Section 11(a) of the Securities Act, no later than 45
     days after the end of a 12-month

     first month of the Company's first fiscal quarter commencing after the
     effective date of the Shelf Registration, which statement shall cover such
     12-month period.

          (m)  The Company shall cause the Indenture (or an indenture
     substantially identical to the indenture in the case of a Registered
     Exchange Offer) to be qualified under the Trust Indenture Act of 1939, as
     amended, containing such changes, if any, as shall be necessary for such
     qualification.

          (n)  The Company may require each Holder of the Notes to be sold
     pursuant to the Shelf Registration Statement to furnish to the Company such
     information regarding the Holder and the distribution of the Notes as the
     Company may from time to time reasonably require for inclusion in the Shelf
     Registration Statement.

          (o)  The Company shall enter into such customary agreements (including
     if requested an underwriting agreement in customary form) and take all such
     other action, if any, as any Holder of the Notes shall reasonably request
     in order to facilitate the disposition of the Notes pursuant to any Shelf
     Registration.

     corporate documents and properties of the Company and (ii) cause the
     Company's officers, directors and employees to supply all relevant
     information reasonably requested by the Initial Purchasers, such

     the foregoing inspection and information gathering shall be coordinated on
     behalf of the Initial Purchasers by you and on behalf of the other parties,
     by one counsel designated by and on behalf of such other parties as
     described in Section 4.

          (t)  If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Notes by Holders to the Company (or to

expenses incurred in connection with the performance of its obligations under
Sections 1 through 3 hereof (including the reasonable fees and expenses of
Mayer, Brown & Platt, counsel for the Initial Purchasers, incurred in connection
with the Registered Exchange Offer), whether or not the Registered Exchange
Offer or a Shelf Registration is filed or becomes effective, and, in the event
of a Shelf Registration, shall bear or reimburse the Holders of the Notes
covered thereby or, if applicable, the Private Exchange Notes covered thereby
for the reasonable fees and disbursements of one firm of counsel designated by
the Holders of a majority in principal amount of the Notes covered thereby and,
if applicable, the Private Exchange Notes covered thereby to act as counsel for
the Holders of the Notes covered thereby, and, if applicable, the Private
Exchange Notes covered thereby in connection therewith.

          5.  Indemnification.  (a)  The Company agrees to indemnify and hold
              ---------------                                                
harmless each Holder of the Notes or, if applicable, the Private Exchange Notes
and each person, if any, who controls such Holder within the meaning of the
Securities Act or the Exchange Act (each Holder and such controlling persons are
referred to collectively as the "Indemnified Parties") from and against any
losses, claims, damages or liabilities, joint or several, or any actions in
respect thereof (including, but not limited to, any losses, claims, damages,
liabilities or actions relating to purchases and sales of the Notes) resulting
from sales made pursuant to a Registration Statement, to which each

                                      -11-

 
Indemnified Party may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as such losses, claims, damages, liabilities or actions
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in a Registration Statement or prospectus or in any
amendment or supplement thereto, or arise out of, or are based upon, the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
shall reimburse, as incurred, the Indemnified Parties for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action in respect thereof;
provided, however, that the Company shall not be liable in any such case to the
- --------  -------                                                              
extent that such loss, claim, damage or liability arises out of or is based upon
any untrue statement or alleged untrue statement or omission or alleged omission
made in a Registration Statement or prospectus or in any amendment or supplement
thereto or in any preliminary prospectus relating to a Shelf Registration in
reliance upon and in conformity with written information pertaining to such
Holder and furnished to the Company by or on behalf of such Holder specifically
for inclusion therein; and provided, further, that this indemnity agreement will
                           --------  -------                                    
be in addition to any liability which the Company may otherwise have to such
Indemnified Party.  The Company shall also indemnify underwriters, selling
brokers, dealer managers and similar securities industry professionals
participating in the distribution (as described in such Registration Statement),
their officers and directors and each person who controls such persons within
the meaning of the Securities Act or the Exchange Act to the same extent as
provided above with respect to the indemnification of the Holders of the Notes
if requested by such Holders.

          (b)  The Company agrees to indemnify and hold harmless each Initial
Purchaser, any Participating Broker-Dealer and each person, if any, who controls
such Initial Purchaser or such Participating Broker-Dealer within the meaning of
the Securities Act or the Exchange Act (each Initial Purchaser, any
participating Broker-Dealer and such controlling persons are referred to
collectively as the "Exchange Offer Indemnified Parties") from and against any
losses, claims, damages or liabilities, joint or several, or any actions in
respect thereof (including, but not limited to, any losses, claims, damages,
liabilities or actions relating to purchases and sales of Exchange Notes), to
which each Exchange Offer Indemnified Party may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such losses, claims,
damages, liabilities or actions arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Exchange Offer Registration Statement or prospectus contained therein or in any
amendment or supplement thereto, or arise out

                                      -12-

 
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and shall reimburse, as incurred, the Exchange Offer
Indemnified Parties for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action in respect thereof; provided, however, that the Company
                                        --------  -------                  
shall not be liable in any such case to the extent that such loss, claim, damage
or liability arises out of or is based upon any untrue statement or alleged
untrue statement or omission or alleged omission made in any Exchange Offer
Registration Statement or prospectus contained therein or in any amendment or
supplement thereto in reliance upon and in conformity with written information
pertaining to such Exchange Offer Indemnified Party and furnished to the Company
by or on behalf of such Initial Purchaser or such Participating Broker-Dealer
specifically for inclusion therein; and provided, further, that this indemnity
                                        --------  -------                     
agreement will be in addition to any liability which the Company may otherwise
have to such Exchange Offer Indemnified Party.

          (c)  Each Holder of the Notes or, if applicable, the Private Exchange
Notes, severally and not jointly, will indemnify and hold harmless the Company
and each person, if any, who controls the Company within the meaning of the
Securities Act or the Exchange Act from and against any losses, claims, damages
or liabilities or any actions in respect thereof, to which the Company or any
such controlling person may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities
or actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in a Registration Statement or prospectus
or in any amendment or supplement thereto or in any preliminary prospectus
relating to a Shelf Registration, or arise out of or are based upon the omission
or alleged omission to state therein a material fact necessary to make the
statements therein not misleading, but in each case only to the extent that the
untrue statement or alleged untrue statement or omission or alleged omission was
made in reliance upon and in conformity with written information pertaining to
such Holder and furnished to the Company by or on behalf of such Holder
specifically for inclusion therein; and, subject to the limitation set forth
immediately preceding this clause, shall reimburse, as incurred, the Company for
any legal or other expenses reasonably incurred by the Company or any such
controlling person in connection with investigating or defending any loss,
claim, damage, liability or action in respect thereof.  This indemnity agreement
will be in addition to any liability which such Holder may otherwise have to the
Company or any of its controlling persons.

                                      -13-

 
          (d)  Promptly after receipt by an indemnified party under this Section
5 of the notice of the commencement of any action or proceeding (including a
governmental investigation), such indemnified party will, if a claim in respect
thereof is to be made against the indemnifying party under this Section 5,
notify the indemnifying party of the commencement thereof; but the omission so
to notify the indemnifying party will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a), (b) or (c) above.  In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof the
indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof.  No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement of any pending
or threatened action in respect of which any 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 any claims that are the subject matter
of such action.

          (e)  If the indemnification provided for in this Section 5 is
unavailable or insufficient to hold harmless an indemnified party under
subsections (a), (b) or (c) above, then each indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of the
losses, claims, damages or liabilities (or actions in respect thereof) referred
to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate
to reflect the relative benefits received by the indemnifying party or parties
on the one hand and the indemnified party on the other from the offering of the
Notes or (ii) if the allocation provided by the foregoing clause (i) is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the indemnifying party or parties on the one hand and the indemnified
party on the other in connection with the statements or omissions that resulted
in such losses, claims, damages or liabilities (or actions in respect thereof)
as well as any other relevant

                                      -14-

 
equitable considerations.  The relative fault of the parties 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 on the one hand or
such Holder or such other indemnified person, as the case may be, on the other,
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.  The amount paid by an
indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (e) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any action or claim which is
the subject of this subsection (e).  Notwithstanding any other provision of this
Section 5(e), the Holders of the Notes or, if applicable, the Private Exchange
Notes shall not be required to contribute any amount in excess of the amount by
which the net proceeds received by such Holders from the sale of the Notes or,
if applicable, the Private Exchange Notes pursuant to a Registration Statement
exceeds the amount of damages which such Holders have otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  For
purposes of this paragraph (e), each person, if any, who controls such
indemnified party within the meaning of the Securities Act or the Exchange Act
shall have the same rights to contribution as such indemnified party and each
person, if any, who controls the Company within the meaning of the Securities
Act or the Exchange Act shall have the same rights to contribution as the
Company.

          (f)  The agreements contained in this Section 5 shall survive the sale
of the Notes, the Exchange Notes or, if applicable, the Private Exchange Notes
pursuant to a Registration Statement and shall remain in full force and effect,
regardless of any termination or cancellation of this Agreement or any
investigation made by or on behalf of any indemnified party.

          6.  Additional Interest Under Certain Circumstances.  (a)  Additional
              -----------------------------------------------                  
interest (the "Additional Interest") with respect to the Notes shall be assessed
as follows:

          (i) if the Exchange Offer Registration Statement in respect of the
     Notes or a Shelf Registration Statement in respect of the Notes is not
     filed with the Commission by June 16, 1995, Additional Interest shall be
     accrued on the Notes over and above the stated interest from and including
     June 17, 1995, until but excluding the earlier of (A) the date the Exchange
     Offer Registration Statement in respect of

                                      -15-

 
     the Notes is filed with the Commission and (B) September 15, 1995, at a
     rate of .50% per annum;

          (ii) if by September 14, 1995, neither the Registered Exchange Offer
     is consummated nor the Shelf Registration Statement in respect of the Notes
     is declared effective by the Commission, Additional Interest shall be
     accrued on the Notes over and above the stated interest from and including
     September 15, 1995, until but excluding the earlier of (A) the date of the
     consummation of the Registered Exchange Offer and (B) the effective date of
     a Shelf Registration Statement in respect of the Notes, at a rate of .50%
     per annum;

          (iii)  Any amounts of Additional Interest due pursuant to clause
     (a)(i) or (a)(ii) of Section 6 above will be payable in cash on the same
     original interest payment dates of the Notes.  The amount of Additional
     Interest will be determined by multiplying the applicable Additional
     Interest rate by the principal amount of the Notes, multiplied by a
     fraction, the numerator of which is the number of days such Additional
     Interest rate was applicable during such period (determined on the basis of
     a 360-day year comprised of twelve 30-day months), and the denominator of
     which is 360.

          (b)  If the Company effects the Registered Exchange Offer, the Company
will be entitled to close the Registered Exchange Offer 30 days after the
commencement thereof provided that the Company has accepted all the Notes
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer.

          7.     Miscellaneous.
                 ------------- 

          (a)  Amendments and Waivers.  The provisions of this Agreement may not
