                            -                                                 
     the Company or any Subsidiary or any of their predecessors, whether such
     action or failure has occurred or is yet to occur or (C) except to the
                                                           -               
     extent that any such Obligation is found in a final judgment by a court of
     competent jurisdiction to have resulted from the gross negligence or
     intentional misconduct of CD&R, the performance by CD&R of management
     consulting, monitoring, financial advisory or other services for MergerCo,
     the Company or any Subsidiary (whether performed prior to the date hereof,
     hereafter, pursuant to the Consulting Agreement or otherwise); and

          (ii) to the fullest extent permitted by applicable law, from and
     against any and all Obligations in any way resulting from, arising out of
     or in connection with, based upon or relating to (A) the fact that such
                                                       -                    
     Indemnitee is or was a director or an officer of MergerCo, the Company or
     any Subsidiary, as the case may be, or is or was serving at the request of
     such corporation as a director, officer, employee or agent of or advisor or
     consultant to another corporation, partnership, joint venture, trust or
     other enterprise or (B) any breach or alleged breach by such Indemnitee of
                          -                                                    
     his or her fiduciary duty as a director or an officer of MergerCo, the
     Company or any Subsidiary, as the case may be;

in each case including but not limited to any and all fees, costs and expenses
(including without limitation fees and disbursements of attorneys) incurred by
or on behalf of any 

                                       6

 
Indemnitee in asserting, exercising or enforcing any of its rights, powers,
privileges or remedies in respect of this Agreement or the Consulting Agreement.

          (b) Without in any way limiting the foregoing Section 2(a), each of
the Indemnifying Parties agrees, jointly and severally, to indemnify, defend and
hold harmless each Indemnitee from and against any and all Obligations resulting
from, arising out of or in connection with, based upon or relating to
liabilities under the Securities Act, the Exchange Act or any other applicable
securities or other laws, rules or regulations in connection with (i) the
                                                                   -     
inaccuracy or breach of or default under any representation, warranty, covenant
or agreement in any Related Document, (ii) any untrue statement or alleged
                                       --                                 
untrue statement of a material fact contained in any Related Document or (iii)
                                                                          --- 
any omission or alleged omission to state in any Related Document a material
fact required to be stated therein or necessary to make the statements therein
not misleading.  Notwithstanding the foregoing, the Indemnifying Parties shall
not be obligated to indemnify such Indemnitee from and against any such
Obligation to the extent that such Obligation arises out of or is based upon an
untrue statement or omission made in such Related Document in reliance upon and
in conformity with written information furnished to MergerCo or the Company as
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
Document.

          3. Contribution.
             ------------ 

          (a) Except to the extent that Section 3(b) is applicable, if for any
reason the indemnity provided for in Section 2(a) is unavailable or is
insufficient to hold harmless any Indemnitee from any of the Obligations covered
by such indemnity, then the Indemnifying Parties, 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 MergerCo, the Company and the 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 the Transactions or any Securities Offering, the
relative benefits received by each of MergerCo, the Company and the
Subsidiaries, on the one hand, and such Indemnitee, on the other, from such
Transaction or Securities Offering and (iii) if 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 the Indemnifying
Parties, 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 MergerCo, the Company
                        -                                                     
and the Subsidiaries, on the one hand, and such indemnitee, on the 

                                       7

 
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 MergerCo, the Company and the Subsidiaries, on
the one hand, and such Indemnitee, on the other, from such Transaction or
Securities Offering and (iii) if required by applicable law, any other relevant
                         ---
equitable considerations.

          (c) For purposes of Section 3(a), the relative fault of each of
MergerCo, the Company and the 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 MergerCo, the Company
and the Subsidiaries, on the one hand, and of the Indemnitee, on the other,
shall be determined by reference to, among other things, (i) whether the
                                                          -             
included or omitted information relates to information supplied by MergerCo, the
Company and the Subsidiaries, 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 MergerCo, the
Company and the Subsidiaries, on the one hand, and the Indemnitee, on the other,
shall be determined by weighing the direct monetary proceeds to MergerCo, the
Company and the Subsidiaries, on the one hand, and such Indemnitee, on the
other, from such Transaction or 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.  The Indemnifying Parties 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 the Indemnifying
Parties would have been 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 the Indemnifying Parties 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 the Indemnifying Parties 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 in writing by any such Indemnitee other than itself, on
behalf of such Indemnitee) or such Indemnitee shall notify the Indemnifying
Parties 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 may 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 of CD&R or such Indemnitee to give such Notice of
Claim shall not relieve the Indemnifying Parties of their respective
indemnification obligations under this Agreement except to the extent that such
omission results in a failure of actual notice to the Indemnifying Parties and
they are materially injured as a result of the failure to give such Notice of
Claim.  The Indemnifying Parties shall, at their expense, undertake the de
fense of such Claim with attorneys of their own choosing reasonably satisfactory
both to CD&R and to any Indemnitee that, in the exercise of such Indemnitee's
good faith judgement, reasonably determines that the Claim presents an actual or
potential conflict of interest with CD&R.  CD&R may participate in such defense
with counsel of CD&R's choosing at the expense of the Indemnifying Parties.  If
in the exercise of their good faith judgment any one or more other Indemnitee
reasonably determines that the Claim presents an actual or potential conflict of
interest with CD&R, such Indemnitee or Indemnitees may participate in the
defense of the Claim with one counsel of the Indemnitee or Indemnitees' choosing
at the expense of the Indemnifying Parties.  In the event that the Indemnifying
Parties do not undertake the defense of the Claim within a reasonable time after
CD&R has given the Notice of Claim, or in the event that CD&R shall in good
faith determine that the defense of any claim by the Indemnifying Parties is
inadequate or may conflict with the interests of any Indemnitee, CD&R may, at
the expense of the Indemnifying Parties and after giving notice to the
Indemnifying Parties 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 the
Indemnifying Parties.  In the defense of any Claim, the Indemnifying Parties
shall not, except with the consent of CD&R (or, in the case of any entry of any
judgment or settlement that is binding on any other Indemnitee, such other
Indemnitee), 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 such 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 the Indemnifying Parties, so long
as the Indemnifying Parties are conducting the defense of the Claim, in the
preparation for and the prosecution of the 

                                       9

 
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 the Indemnifying Parties.

          (b) The Indemnifying Parties 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 be indemnified by the
Indemnifying Parties as authorized by this Agreement.

          (c) Each Indemnitee shall notify the Indemnifying Parties in writing
of the amount of any Claim actually paid by such Indemnitee (the "Notice of
                                                                  ---------
Payment").  The amount of any Claim actually paid by an Indemnitee shall bear
- -------                                                                      
simple interest at the rate equal to Credit Suisse First Boston's prime rate as
of the date of such payment plus 2% per annum, from the date the Indemnifying
Parties receive the Notice of Payment to the date on which the Indemnifying
Parties shall repay the amount of such Claim plus interest thereon to such
Indemnitee.

          5.   Certain Covenants.  The Company and TTC jointly and severally
               -----------------                                            
agree to perform their 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 the Company hereunder shall remain in full
force and effect regardless of any investigation made by or on behalf of such
Indemnitee.  The Indemnifying Parties shall implement and maintain in full force
and effect any and all corporate articles or charter and by-law provisions that
may be necessary or appropriate to enable them to carry out their obligations
hereunder to the fullest extent permitted by applicable corporate law, including
without limitation a provision of their articles or certificate of incorporation
eliminating liability of a director for breach of fiduciary duty to the fullest
extent permitted by applicable corporate law, as it may be amended from time to
time.

including as to validity, interpretation and effect, by the law of the State of
New York without giving effect to its principles or rules of conflict of laws to
the extent such principles or rules would require or permit the application of
the laws of another jurisdiction, except to the extent that the corporate law of
another jurisdiction 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 the Company or TTC without the prior written consent of 

                                       12

 
CD&R and the CD&R 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 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.

                                       13

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