3.1 Subject to the terms of this Guarantee, TR Corporation unconditionally and irrevocably undertakes and promises to TR PLC that it shall, as a continuing obligation, make to the Creditor to whom or to which it is owed (the “Relevant Creditor”) the proper and punctual payment of each Obligation if for any reason TR PLC does not make such payment on its due date. If for any reason TR PLC does not make such payment on its due date, TR Corporation shall pay the amount due and unpaid to the Relevant Creditor upon written demand upon TR Corporation by the Relevant Creditor. In this Clause 3, references to the Obligations include references to any part of them.

3.2 The obligations of TR Corporation under this Guarantee shall be continuing obligations and shall not be satisfied, discharged or affected by any intermediate payment or settlement of account.

3.3 In the event that TR Corporation is required to make any payment to any Creditor pursuant to Clause 3.1 and/or Clause 3.10 and does make such payment, TR PLC unconditionally and irrevocably agrees by way of a full indemnity (on an after-tax basis) to reimburse TR Corporation in respect of such payments, including interest thereon (payable from the date of demand for payment both before and after default and judgment) at LIBOR, plus 20 basis points per annum.

3.4 A demand may not be made under this Guarantee without:

(A) a demand first having been made by the Relevant Creditor on TR PLC; and

(B) to the extent, if any, that the terms of the relevant Obligation of TR PLC (or the underlying obligation of the relevant Principal Debtor) require such recourse, recourse first being had to any other Person or to any security.

3.5 Unless otherwise provided in this Guarantee, the liabilities and obligations of TR Corporation under this Guarantee shall remain in force notwithstanding any act, omission, neglect, event or matter which would not affect or discharge the liabilities of TR PLC owed to the Relevant Creditor. Without prejudice to its generality, the foregoing shall apply in relation to:

(A) anything which would have discharged TR Corporation (wholly or in part) but not TR PLC;

(B) anything which would have offered TR Corporation (but not TR PLC) any legal or equitable defence; and

(C) any winding-up, insolvency, dissolution and/or analogous proceeding of, or any change in constitution or corporate identity or loss of corporate identity by, TR PLC or any other Person.

3.6 Sections 3(2) and (4) of the Contracts (Rights of Third Parties) Act 1999 shall not apply to this Guarantee and accordingly:

(A) in respect of any claim against TR Corporation by a Creditor, TR Corporation shall not have available to it by way of defence or set-off any matter that arises from or in connection with this Guarantee, and which would have been available to TR Corporation by way of defence or set-off if the proceedings had been brought against TR Corporation by TR PLC;

(B) TR Corporation shall not have available to it by way of defence or set-off any matter that would have been available to it by way of defence or set-off against the Creditor if the Creditor had been a party to this Guarantee; and

(C) TR Corporation shall not have available to it by way of counterclaim any matter not arising from this Guarantee that would have been available to it by way of counterclaim against the Creditor if the Creditor had been a party to this Guarantee.

3.7 Any discharge or release of any liabilities and obligations of TR Corporation under this Guarantee, and any composition or arrangement which TR Corporation may effect with any Creditor in respect of any such liabilities or obligations, shall be deemed to be made subject to the condition that it will be void to the extent that any or all of the payment or security which the Creditor may previously have received or may thereafter receive from

any Person in respect of the relevant Obligations is set aside or reduced under any applicable law or proves to have been for any reason invalid.

3.8 Without prejudice to the generality of this Clause 3, and to Clause 3.9 in particular, none of the liabilities or obligations of TR Corporation under this Guarantee shall be impaired by any Creditor:

(A) agreeing with TR PLC any composition, arrangement, variation of or departure from (however substantial) the terms of any Obligation and any such composition, arrangement, variation or departure shall, whatever its nature, be binding upon TR Corporation in all circumstances; or

(B) releasing or granting any time or any indulgence whatsoever to TR PLC.

3.9 (A) Despite anything else in Clause 3, but subject to paragraph (B) below, if and to the extent that the relevant Creditor (or any Person duly acting on behalf of the relevant Creditor) at any time before or after the date of this Guarantee explicitly agrees with TR PLC or grants to TR PLC any discharge, release, composition, arrangement, variation, departure, time, indulgence or other limitation (whether as to amount, recourse or otherwise) of any kind in respect of any Obligation, it shall automatically operate for the benefit of, and be binding upon, TR Corporation to the same extent.

(B) Despite anything else in this Guarantee (including Clause 3.8), no composition, arrangement, variation of or departure from the terms of any Obligation (or any underlying obligation of any Principal Debtor) agreed with TR PLC or any Principal Debtor, as applicable, after termination of this Guarantee or exclusion of that Obligation from the scope of this Guarantee shall be binding on TR Corporation (or extend its liabilities and obligations under this Guarantee) except to the extent, if any, that:

(i) TR Corporation explicitly agrees in writing to that composition, arrangement, variation or departure at the same time as TR PLC or that Principal Debtor; or

(ii) it reduces TR Corporation’s obligations or liability under this Guarantee.

3.10 Subject to Clause 3.4, as a separate, additional and continuing obligation, TR Corporation unconditionally and irrevocably agrees that, should any Obligation not be recoverable from TR Corporation under Clause 3.1 as a result of the Obligation becoming void, voidable or unenforceable against TR PLC, TR Corporation will, as a sole, original and independent obligor, make payment of the Obligation to the Relevant Creditor by way of a full indemnity on the due date provided for payment by the terms of the Obligation.

3.11 TR Corporation shall, if requested by TR PLC, (i) enter into agreements to act as a co-issuer or co-borrower with respect to any Obligation of TR PLC or (ii) execute and deliver a separate guarantee agreement of any Obligation of TR PLC, in each case, on terms satisfactory to TR Corporation and TR PLC.

agree that such Obligation shall be excluded from the scope of this Guarantee in accordance with Clause 4.
