                  1.05 Third-Party Consents. To the extent that any Contract is
not assignable without the consent of another party, this Agreement shall not
constitute an assignment or an attempted assignment thereof if such assignment
or attempted assignment would constitute a breach of or a default under any
Contract either constituting or governing such Contract. TCR Holding shall use
its best efforts to obtain the consent of such other party to the assignment of
any such Contract in all cases in which such consent is or may be required for
such assignment. If any such consent shall not be obtained, TCR Holding shall
cooperate with TransContinental in any arrangement designed to provide
TransContinental with the benefits intended to be assigned to TransContinental
under or pursuant to such Contract, including enforcement at the cost and for
the account of TCR Holding of any and all rights of TCR Holding against the
other party thereto arising out of the breach or cancellation thereof by such

   6

                                 INDEMNIFICATION

                  2.01 Indemnification.

                  (a) TCR Holding shall indemnify TransContinental, its
officers, directors, Affiliates, agents and representatives and their respective
successors and assigns (collectively, the "TransContinental Parties") in respect
of, and hold the TransContinental Parties harmless from and against, any and all
Losses suffered, incurred or sustained, as suffered, incurred or sustained by
any of them or to which any of them becomes subject, resulting from, arising out
of or relating to (i) any breach of representation or warranty or nonfulfillment
of or failure to perform any agreement on the part of TCR Holding contained in
this Agreement or (ii) the Retained Assets or any Retained Liability.

                  (b) TransContinental shall indemnify TCR Holding, its
officers, directors, Affiliates, agents and representatives and their respective
successors and assigns (collectively, the "TCR Parties") in respect of, and
hold TCR Holding harmless from and against, any and all Losses suffered,
incurred or sustained by any of them or to which any of them becomes subject,
resulting from, arising out of or relating to the Assets or the Assumed
Liabilities except to the extent that any such loss arises out of any Loss
giving rise to indemnification under Section 2.01(a).

                  2.02 Survival of Indemnity and Representations and Warranties.
The indemnity provisions contained in this Article II shall survive indefinitely
regardless of (i) any investigation made at any time by or on behalf of any
TransContinental Party, (ii) any termination of this Agreement or the Securities
Purchase Agreement or (iii) acceptance of the Assets by TransContinental.

                  2.03 Indemnification Procedures. An Indemnified Party shall
give the party obligated to provide indemnification under Section 2.01 (the
"Indemnified Party") notice of any matter which an Indemnified Party has
determined has given or could give rise to a right of indemnification under this
Agreement, within 90 days of such determination, stating the amount of the Loss,
if known, and method of computation thereof, and containing a reference to the
provisions of this Agreement in respect of which such right of indemnification
is claimed or arises; provided, however, that the failure to provide such notice
shall not release the Indemnifying Party from any of its obligations under this
Article II except to the extent the Indemnifying Party is materially prejudiced
by such failure and shall not relieve the Indemnifying Party from any other
obligation or liability that it may have to any Indemnified Party otherwise than
under this Article II. The obligations and Liabilities of an Indemnifying Party
under this Article II with respect to Losses arising from claims of any third
party which are subject to the indemnification provided for in this Article II
("Third Party Claims") shall be governed by and contingent upon the following
additional terms and conditions: if an Indemnified Party shall receive notice of
any Third Party Claim, the Indemnified Party shall give the Indemnifying Party
notice of such Third Party Claim within 30 days of the receipt by the
Indemnified Party of such notice; provided, however, that the failure to provide
such notice shall 

   7

not release the Indemnifying Party from any of its obligations under this
Article II except to the extent the Indemnifying Party is materially prejudiced
by such failure and shall not relieve the Indemnifying Party from any other
obligation or liability that it may have to any Indemnified Party otherwise than
under this Article II. If the Indemnifying Party acknowledges in writing its
obligation to indemnify the Indemnified Party hereunder against any Losses that
may result from such Third Party Claim, then the Indemnifying Party shall be
entitled to assume and control the defense of such Third Party Claim at its
expense and through counsel of its choice if it gives notice of its intention to
do so to the Indemnified Party; provided, however, that if there exists or is
reasonably likely to exist a conflict of interest that would make it
inappropriate in the judgment of the Indemnified Party, in its sole and absolute
discretion, for the same counsel to represent both the Indemnified Party and the
Indemnifying Party, then the Indemnified Party shall be entitled to retain its
own counsel, in each jurisdiction for which the Indemnified Party determines
counsel is required, at the expense of the Indemnifying Party; provided further,
that in no event shall the Indemnifying Party be obligated to pay the fees and
expenses of more than one independent counsel for all Indemnified Parties in
each such jurisdiction. In the event the Indemnifying Party exercises the right
to undertake any such defense against any such Third Party Claim as provided
above, the Indemnified Party shall cooperate with the Indemnifying Party in such
defense and make available to the Indemnifying Party, at the Indemnifying
Party's expense, all witnesses, pertinent records, materials and information in
the Indemnified Party's possession or under the Indemnified Party's control
relating thereto as is reasonably required by the Indemnifying Party. Similarly,
in the event the Indemnified Party is, directly or indirectly, conducting the
defense against any such Third Party Claim, the Indemnifying Party shall
cooperate with the Indemnified Party in such defense and make available to the
Indemnified Party, at the Indemnifying Party's expense, all such witnesses,
records, materials and information in the Indemnifying Party's possession or
under the Indemnifying Party's control relating thereto as is reasonably
required by the Indemnified Party. No such Third Party Claim may be settled
without the prior written consent of each Indemnified Party subject to such
Third Party Claim unless such settlement (i) includes an unconditional release
of both the Indemnifying Party and each Indemnified Party from all liability
arising out of such Third Party claim and (ii) does not include a statement as
to or an admission of fault, culpability or a failure to act by or on behalf of
either the Indemnifying Party or any Indemnified Party. 

                                  ARTICLE III

                                       TAX

this Agreement, and shall indemnify, defend, and hold harmless TCR Holding on an
after-Tax basis with respect to such Transfer Taxes. TransContinental shall file
all necessary documentation and Tax Returns with respect to such Transfer Taxes.

                  3.02 Tax Cooperation. After the Closing Date, TCR Holding and
the affiliated group of which it is a member will cooperate in the preparation
of all Tax Returns, will provide any records and other information that TRC
Holding requests, will provide access to, and the cooperation of, its auditor,
and will cooperate with TRC Holding in connection with any Tax investigation,
audit or other proceeding.

out-of-pocket expenses and costs resulting from, arising out of or relating to,
all Taxes imposed on TCR Holding or any member of the affiliated group of which
TCR Holding is a member, including Taxes imposed on TCR Holding or any such
