        4. POST TERMINATION TRANSITION. The provisions of this Section 4 shall
apply commencing on the Termination Date notwithstanding anything in the
Representation Agreement to the contrary:

               4.1. Employees. The parties agree that the provisions of Sections
3.3(a), (b) and (c) of the Representation Agreement shall continue to apply

such date and Geneva will fund such receivables to Mannesmann within five (5)
days after having received notice of such assignment.

               4.3. Geneva Option. Notwithstanding the payment dates provided
for in Section 4.2 above, if the aggregate of such payment exceeds $3 million
Geneva shall have the right to defer the assignment of Open Accounts and payment
of such amount through and including December 28, 2000 upon the giving of at
least thirty (30) days prior written notice to Mannesmann.

               4.4. Administration of Open Orders. Mannesmann, upon Geneva's
request, shall continue to administer all orders that are open on the
Termination Date, including, but not limited to, making payment for any material
delivered or produced and identified to such orders, such payment to be made by

Agreement. The administration of any orders which remain open after September
30, 2000 shall become the responsibility of Geneva, and any payments which
Mannesmann may have made for material under such orders that remain undelivered
at such time shall be refunded to Mannesmann no later than October 5, 2000. If
any warehouse receipt has been issued for any of the material covered by such
order, as a condition to such payment Mannesmann shall deliver to Geneva the
original of such warehouse receipt(s) and thereupon title to such material shall
vest in Geneva. Mannesmann shall promptly cause any protective form UCC-1 filed
in any state with respect to such material to be terminated and released of
record.

               4.5. No Affect on Other Provisions. Except as expressly set forth
in this Section 4, the provisions of the Representation Agreement intended to
survive termination shall survive such termination, including, but not limited
to, the provisions of Section 3.3(d) and Section 12 thereof which the parties
hereby agree shall apply in full force and effect notwithstanding the
termination effected by this Agreement.

        5. EX-L-TUBE SETTLEMENT. Concurrently with the execution of this
Agreement, the parties agree to enter into that certain Settlement Agreement

Mannesmann hereby waives any claim or right or remedy against Ex-L-Tube or
Geneva in relation to the matters that are the subject of the
Ex-L-Tube-Settlement, including any right to any additional payment. In the
event the payment of the Initial Settlement Amount received by Geneva from
Ex-L-Tube should for any reason subsequently be determined to be void, avoidable
or the property of another, in whole or in part, including, without limitation,
fraudulent conveyances, preferential transfers or property subject to a prior
perfected security interest or lien of another entity, and if Geneva is required
to repay or restore any portion thereof, or, upon the advice of Geneva's
counsel, does so after demand, then, as to such amount repaid or restored,
Mannesmann shall immediately pay to Geneva its pro rata portion of such amount
repaid or restored.

        6. WAIVER OF PRE-PETITION CLAIMS BY MANNESMANN. In consideration of
Geneva's entering into this Agreement, Mannesmann has agreed to waive and
release and hereby waives and releases all pre-petition claims, disputes and
controversies against Geneva arising out of the Representation Agreement and

Proceeding , including, without limitation all such claims of Mannesmann filed
or listed, or which could have been filed or listed, in the Chapter 11
Proceeding but excluding those pre-petition product claims, if any, identified
in Section 8 hereof. Without limiting the generality of the foregoing,
Mannesmann expressly waives and releases all claims identified in the Proof of
Claim filed by Mannesmann on July 30, 1999, a copy of which is attached hereto
as Exhibit 6.

        7. MUTUAL RELEASE OF CLAIMS. In consideration of Mannesmann's release of
its Proof of Claim and Geneva's assumption of the Representation Agreement, the
parties hereby release and discharge each other from all claims and obligations,
except for the obligations set forth in and claims arising under this Agreement
and, subject to Section 6 hereof, the Representation Agreement as assumed.
