fact required to be stated therein or necessary to make the statements therein

the case may be, in an instrument duly executed by such Indemnitee and
specifically stating that it is for use in the preparation of such Related

reason the indemnity provided for in Section 2(a) is unavailable or is

contribute to the amount paid or payable by such Indemnitee as a result of such
Obligation in such proportion as is appropriate to reflect (i) the relative
                                                            -              
fault of each of Holding, the Company and their Subsidiaries, on the one hand,
and such Indemnitee, on the other, in connection with the state of facts giving
rise to such Obligation, (ii) if such Obligation results from, arises out of, is
                          --                                                    
based upon or relates to any Securities Offering, the relative benefits received
by each of Holding, the Company and their Subsidiaries, on the one hand, and

required by applicable law, any other relevant equitable considerations.

          (b) If for any reason the indemnity specifically provided for in
Section 2(b) is unavailable or is insufficient to hold harmless any Indemnitee
from any of the Obligations covered by such indemnity, then Holding and the
Company,jointly and severally, shall contribute to the amount paid or payable by
such Indemnitee as a result of such Obligation in such proportion as is
appropriate to reflect (i) the relative fault of each of Holding, the Company
                        -                                                    
and their Subsidiaries, on the one hand, and such Indemnitee, on the other, in
connection with the information contained in or omitted from any Related
Document, which inclusion or omission resulted in the inaccuracy or breach of or
default under any representation, warranty, covenant or agreement therein, or
which information is or is alleged to be untrue, required to be stated therein
or necessary to make the statements therein not misleading, (ii) the relative
                                                             --              
benefits received by Holding, the Company and their Subsidiaries, on the one
hand, and such Indemnitee, on the other, from such Securities Offering and (iii)
                                                                            --- 
if required 

                                       8

 
by applicable law, any other relevant equitable considerations.

          (c) For purposes of Section 3(a), the relative fault of each of
Holding, the Company and their Subsidiaries, on the one hand, and of the
Indemnitee, on the other, shall be determined by reference to, among other
things, their respective relative intent, knowledge, access to information and
opportunity to correct the state of facts giving rise to such Obligation.  For
purposes of Section 3(b), the relative fault of each of Holding, the Company and
their Subsidiaries, on the one hand, and of the Indemnitee, on the other, shall

                                                    -                         
omitted information relates to information supplied by Holding, the Company or a
Subsidiary, on the one hand, or by such Indemnitee, on the other, and (ii) their
                                                                       --       
respective relative intent, knowledge, access to information and opportunity to
correct such inaccuracy, breach, default, untrue or alleged untrue statement, or
omission or alleged omission.  For purposes of Section 3(a) or 3(b), the
relative benefits received by each of Holding, the Company and their
Subsidiaries, on the one hand, and the Indemnitee, on the other, shall be
determined by weighing the direct monetary proceeds to Holding, the Company and
their Subsidiaries, on the one hand, and such Indemnitee, on the other, from
such Securities Offering.

          (d) The parties hereto acknowledge and agree that it would not be just
and equitable if contributions pursuant to Section 3(a) or 3(b) were determined
by pro rata allocation or by any other method of allocation that does not take
into account the equitable considerations referred to in such respective
Section.  Holding and the Company shall not be liable under Section 3(a) or
3(b), as applicable, for contribution to the amount paid or payable by any
Indemnitee except to the extent and under such circumstances as Holding or the
Company would have been 

                                       9

 
liable to indemnify, defend and hold harmless such Indemnitee under the
corresponding Section 2(a) or 2(b), as applicable, if such indemnity were
enforceable under applicable law. No Indemnitee shall be entitled to
contribution from Holding or the Company with respect to any Obligation covered
by the indemnity specifically provided for in Section 2(b) in the event that
such Indemnitee is finally determined to be guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
in connection with such Obligation and Holding and the Company are not guilty of
such fraudulent misrepresentation.

          4.  Indemnification Procedures.
              -------------------------- 

          (a) Whenever any Indemnitee shall have actual knowledge of the
reasonable likelihood of the assertion of a Claim, CD&R (acting on its own
behalf or, if requested by any such Indemnitee other than itself, on behalf of
such Indemnitee) or such Indemnitee shall notify Holding or the Company, as the
case may be, in writing of the Claim (the "Notice of Claim") with reasonable
promptness after such Indemnitee has such knowledge relating to such Claim and
has notified CD&R thereof.  The Notice of Claim shall specify all material facts
known to CD&R (or if given by such Indemnitee, such Indemnitee) that give rise
to such Claim and the monetary amount or an estimate of the monetary amount of
the Obligation involved if CD&R (or if given by such Indemnitee, such
Indemnitee) has knowledge of such amount or a reasonable basis for making such
an estimate. The failure to give such Notice of Claim shall not relieve Holding
and the Company of their respective indemnification obligations under this
Agreement except to the extent that such omission results in a failure of actual
notice to them and they are materially injured as a result of the failure to
give such Notice of Claim.  Holding and the Company shall, at their expense,
undertake the defense of such Claim with attorneys of their own choosing
satisfactory in all re-

                                       10

 
spects to CD&R. CD&R may participate in such defense with counsel of CD&R's
choosing at the expense of Holding and the Company. In the event that none of
Holding and the Company undertakes the defense of the Claim within a reasonable
time after CD&R has given the Notice of Claim, CD&R may, at the expense of
Holding and the Company and after giving notice to Holding and the Company of
such action, undertake the defense of the Claim and compromise or settle the
Claim, all for the account of and at the risk of Holding and the Company. In the
defense of any Claim, Holding and the Company shall not, except with the consent
of CD&R, consent to entry of any judgment or enter into any settlement that
includes any injunctive or other non-monetary relief, or that does not include
as an unconditional term thereof the giving by the person or persons asserting
such Claim to each Indemnitee of a release from all liability with respect to
such Claim. In each case, CD&R and each other Indemnitee seeking indemnification
hereunder will cooperate with Holding and the Company, so long as Holding and
the Company are conducting the defense of the Claim, in the preparation for and
the prosecution of the defense of such Claim, including making available
evidence within the control of CD&R or such Indemnitee, as the case may be, and
persons needed as witnesses who are employed by CD&R or such Indemnitee, as the
case may be, in each case as reasonably needed for such defense and at cost,
which cost, to the extent reasonably incurred, shall be paid by Holding and the
Company.

          (b) Holding and the Company hereby agree to advance costs and
expenses, including attorney's fees, incurred by CD&R (acting on its own behalf
or, if requested by any such Indemnitee other than itself, on behalf of such
Indemnitee) or any Indemnitee in defending any Claim in advance of the final
disposition of such Claim upon receipt of an undertaking by or on behalf of CD&R
or such Indemnitee to repay amounts so advanced if it shall ultimately be
determined that CD&R or such Indemnitee is not entitled to 

                                       11

 
be indemnified by Holding and the Company as authorized by this Agreement.

          (c) CD&R shall notify Holding and the Company in writing of the amount
of any Claim actually paid by CD&R (the "Notice of Payment").  The amount of any
Claim actually paid by CD&R shall bear simple interest at the rate equal to the
prime rate most recently set forth in The Wall Street Journal as of the date of
                                      -----------------------                  
such payment plus 2% per annum, from the date Holding or the Company receives
the Notice of Payment to the date on which Holding or the Company shall repay
the amount of such Claim plus interest thereon to CD&R.

          5.   Certain Covenants.  Holding agrees to cause the Company to
               -----------------                                         
perform its obligations under this Agreement. The rights of each Indemnitee to
be indemnified under any other agreement, document, certificate or instrument or
applicable law are independent of and in addition to any rights of such
Indemnitee to be indemnified under this Agreement.  The rights of each
Indemnitee and the obligations of Holding and the Company hereunder shall remain
in full force and effect regardless of any investigation made by or on behalf of
such Indemnitee.  Each of Holding and the Company shall maintain the State of
Delaware as its state of incorporation and shall implement and maintain in full
force and effect any and all corporate charter and by-law provisions that may be
necessary or appropriate to enable it to carry out its obligations hereunder to
the fullest extent permitted by Delaware corporate law, including without
limitation a provision of its certificate of incorporation eliminating liability
of a director for breach of fiduciary duty to the fullest extent permitted by
Section 102(b)(7) (or any successor section thereto) of the General Corporation
Law of the State of Delaware, as it may be amended from time to time.

including validity, interpretation and effect, by the law of the State of New

of laws, except to the extent that the corporate law of the State of Delaware
specifically and mandatorily applies, in which case such law shall apply.

          8.   Severability.  If any provision or provisions of this Agreement
               ------------                                                   
shall be held to be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions hereof shall not in any way be
affected or impaired thereby.

          9.   Miscellaneous.  The headings contained in this Agreement are for
               -------------                                                   
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.  This Agreement shall be binding upon and
inure to the benefit of each party hereto and its successors and permitted
assigns, and each other Indemnitee, but neither this Agreement nor any right,
interest or obligation hereunder shall be assigned, whether by operation of law
or otherwise, by Holding or the Company without the prior written consent of
CD&R and the C&D Fund.  This Agreement is not intended to confer any right or
remedy hereunder upon any person other than each of the parties hereto and their
respective successors and permitted assigns and each other Indemnitee.  No
amendment, modification, supplement or 

                                       14

 
discharge of this Agreement, and no waiver hereunder shall be valid and binding
unless set forth in writing and duly executed by the party or other Indemnitee
against whom enforcement of the amendment, modification, supplement or discharge
is sought. Neither the waiver by any of the parties hereto or any other
Indemnitee of a breach of or a default under any of the provisions of this
Agreement, nor the failure by any party hereto or any other Indemnitee on one or
more occasions, to enforce any of the provisions of this Agreement or to
exercise any right, powers or privilege hereunder, shall be construed as a
waiver of any other breach or default of a similar nature, or as a waiver of any
provisions hereof, or any rights, powers or privileges hereunder. The rights and
remedies herein provided are cumulative and are not exclusive of any rights or
remedies that any party or other Indemnitee may otherwise have at law or in
equity or otherwise. This Agreement may be executed in several counterparts,
each of which shall be deemed an original, and all of which together shall
constitute one and the same instrument.

                                       15

 
          IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement by their authorized representatives as of the date first above
written.
