order to (a) allow (i) Hedge Agreements entered into by Tenneco Management
(Europe) Limited or any Subsidiary that succeeds Tenneco Management (Europe)

Collateral and guaranteed pursuant to the Security Documents, (b) update the
Security Documents for changes in law, including changes in the Uniform
Commercial Code, (c) add additional Collateral thereunder and (d) effect other
similar changes. In furtherance of the foregoing, the parties hereto agree that,
upon or following the effectiveness of this Fourth Amendment, the Guarantee and
Collateral Agreement (including the schedules and annexes thereto) may be
amended, amended and restated, or otherwise modified as the Borrower and the
Administrative Agent shall agree from time to time for the purposes of (i)
updating the terms of the Guarantee and Collateral Agreement to conform to
changes in law, including revisions to Article 9 of the Uniform Commercial Code,
(ii) refining the representations, warranties and covenants contained therein
with respect to the description of and perfection of security interests in
foreign and ancillary intellectual property collateral and (iii) conforming the
representation in Section 4.2 thereof in a manner consistent with the
representation set forth in Section 4.19(a) of the Credit Agreement, as amended
by this Fourth Amendment.




                                                                               8


                  6. Continuing Effect of the Credit Agreement. This Fourth
Amendment shall not constitute an amendment of any provision of the Credit
Agreement not expressly referred to herein and shall not be construed as a
waiver or consent to any further or future action on the part of the Borrower
that would require a waiver or consent of the Lenders, the Administrative Agent
or the Other Agents. Except as expressly amended hereby, the provisions of the
Credit Agreement are and shall remain in full force and effect. Sections 2(d)
and 5 of this Fourth Amendment shall be deemed to be in effect for all
applicable periods prior to the Effective Date.

                  7. Counterparts. This Fourth Amendment may be executed by the
parties hereto in any number of separate counterparts (including telecopied
counterparts), each of which shall be deemed to be an original, and all of which
taken together shall be deemed to constitute one and the same instrument.

                  8. GOVERNING LAW. THIS FOURTH AMENDMENT SHALL BE GOVERNED BY,
AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK.
