Administrative Agent's failure to make such demand for payment under the Equity
Letter of Credit shall not relieve the Equity Contributor of its obligations

provisions corresponding to the provisions hereof for an equity contribution
to be made by GTS Sponsor. In the event that GTS Sponsor is in default of its
obligations under its Equity Contribution Agreement and the Equity
Contributor is in default of its obligations under this Agreement, then the
Administrative Agent agrees that it will act in parallel to initiate remedies
available under the respective Equity Contribution Agreements whether such
initiative is by demand, drawing upon the Equity Letter of Credit (and the
letter of credit provided by the LOC Issuer of GTS Sponsor) or exercise of
remedies of enforcement available pursuant to the respective Equity
Contribution Agreements. Except as expressly provided for herein, this
undertaking shall in no respect diminish or delay the exercise by the
Administrative Agent of all rights available pursuant to the Equity Letter of
Credit, the Letter of Credit provided by the LOC Issuer of GTS Sponsor and
the respective Equity Contribution Agreements. Notwithstanding anything to
the contrary provided for in Section 2.1 and Section 4.9 of this Agreement,
in the event that the exercise of rights by the Administrative Agent under
either Equity Contribution Agreement should be delayed, deferred, enjoined or
for any other reason whatsoever the Administrative Agent is unable to
exercise in full or realize in full its rights and obligations under either
Equity Contribution Agreement, the Administrative Agent may proceed in the
exercise of its remedies under the other Equity Contribution Agreement to the
fullest extent permitted by law. It is expressly acknowledged by the
Administrative Agent that the Equity Contribution Agreement entered into by
GTS Sponsor (as defined in Section 4.7) has a provision corresponding to this
provision.

     Section 4.8. SUBSTANTIAL SIMILARITY. It is confirmed by the
Company and the Administrative Agent that GTS Transatlantic Holdings ("GTS
SPONSOR") has entered into an Equity Contribution Agreement (the "GTS EQUITY
CONTRIBUTION AGREEMENT") on substantially the same terms as the terms of this
Agreement.

     Section 4.9. CALLS AND DEMANDS. It is agreed that the Company
and the Administrative Agent will to the extent that equal amounts are due under
each such agreements, make parallel calls and demands under this Agreement and
the GTS Equity Contribution Agreement (and if required under any supporting
Letter of Credits) at the same time and for the same amounts and (without
prejudice to section 4.7) will use all


                                         10

<PAGE>


reasonable endeavors to enforce such calls and demands with a view to treating
the Equity Contributor and the GTS Sponsor on an equal footing.

     Section 4.10. SEVERABILITY OF PROVISIONS. Any provision of
this Agreement which is prohibited or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     Section 4.11. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
each party hereto, and on their permitted successors and assigns, and shall
inure to the benefit of the Company and its successors and assigns; PROVIDED,
HOWEVER, that neither the Company nor the Equity Contributor shall transfer or
assign all or any portion of its obligations under this Agreement without the
prior written consent of the other and the Administrative Agent. The Equity
Contributor hereby consents to the collateral assignment of this Agreement by
the Company to the Administrative Agent for the benefit of the Secured Parties
pursuant to the Company Security Agreement (U.S.) or otherwise, and the Equity
Contributor hereby agrees that (i) pursuant to the exercise of remedies under
any of the Financing Documents the Administrative Agent or its designee or
transferee may succeed to the rights, powers, privileges, interests and remedies
of the Company, whether arising under this Agreement or by statute or in law or
in equity or otherwise and (ii) the Administrative Agent either as party to or
third party beneficiary of this Agreement shall have the right to enforce
directly the provisions hereof against each of the parties hereto. The Equity
Contributor shall be fully protected in making payments to the Administrative
Agent hereunder, such payments shall fully discharge the Equity Contributor's
obligations to the Company or any other Person hereunder and under no
circumstances may the Equity Contributor be required to make Equity
Contributions hereunder that exceed, together with all amounts available to be
drawn under the Equity Letter of Credit and Limited Guarantee Agreement (FLAG),
the Equity Contribution Commitment.

     Section 4.12. HEADINGS DESCRIPTIVE. The headings of the several sections of
this Agreement are inserted for convenience only and shall not in any way affect
