On the first Business Day after such Defaulting Lender obtains written acknowledgment of the Borrower, the Administrative Agent and each Multicurrency Issuing Lender acknowledging the cure of all (but not less than all) Specified Lender Defaults of such Lender (such date, the “Reinstatement Date”), (a) such Lender will no longer be deemed to be a Defaulting Lender under this Agreement, (b) all such Lender’s voting rights and rights to payment under the Loan Documents that were

suspended as a result of its status as a Defaulting Lender shall be restored and (c) the Borrower shall no longer have the right to replace such Lender pursuant to Section 2.24 with respect to the cured Specified Lender Defaults. Prior to any Reinstatement Date, each Defaulting Lender shall remain liable to the Borrower and the other Loan Parties for any and all damages arising out of, in connection with, or as a result of, each Specified Lender Default, consistent with the terms of this Agreement. If one or more additional Lender defaults occur after the Reinstatement Date with respect to such Lender, the prior written consent of the Required Lenders in their sole discretion and, so long as no Event of Default shall have occurred and be continuing, the Borrower in its sole discretion shall be required to restore such Lender as a non-Defaulting Lender.

(c) Notwithstanding anything in this Agreement to the contrary, (i) prior to and as of the First Amendment Effective Date, LCPI shall not be, nor shall it be deemed to be, a Defaulting Lender and (ii) at no time on or after the First Amendment Effective Date shall LCPI be or be deemed to be (x) an Impacted Lender or (y) a Defaulting Lender under clause (a) (other than any obligations arising after the First Amendment Effective Date under Section 2.26) or clause (c) of the definition thereof.

SECTION 1.07. Resignation and Waiver. Each of the Lenders party hereto hereby (i) acknowledges the resignation of LCPI as Administrative Agent under the Loan Documents, (ii) waives the requirement under Section 9.9 of the 2007 Credit Agreement that LCPI provide 30 days’ prior written notice prior to its resignation under the Assignment and Assumption becoming effective and (iii) agrees that LCPI’s resignation as Administrative Agent shall become effective as of the Effective Date.

SECTION 1.08. LCPI and the Amended Credit Agreement. The parties hereto hereby confirm that, as of the date hereof, all of the provisions of the Amended Credit Agreement (including, without limitation, Section 9 and Section 10.5, to the extent they pertain to LCPI as Administrative Agent, and Section 2.21, to the extent it pertains to LCPI as Lender), continue in effect for the benefit of LCPI, its sub-agents and their respective affiliates in respect of any actions taken or omitted to be taken by any of them as Administrative Agent or a sub-agent thereof or as a Lender, as the case may be, and inure to the benefit of LCPI.

SECTION 1.09. LCPI as Bailee. On and after the Effective Date, all possessory collateral held by LCPI for the benefit of the Lenders or Secured Parties, as applicable shall be deemed to be held by LCPI as agent and bailee for the Successor Administrative Agent for the benefit of the Lenders or Secured Parties, as applicable, until such time as such possessory collateral has been delivered to the Successor Administrative Agent. Notwithstanding anything herein to the contrary, each Loan Party agrees that all of such Liens granted by any Loan Party, shall in all respects be continuing and in effect and are hereby ratified and reaffirmed by each Loan Party. Without limiting the generality of the foregoing, any reference to LCPI on any publicly filed document, to the extent such filing relates to the liens and security interests in the Collateral assigned hereby or by the Assignment and Assumption and until such filing is modified to reflect the interests of the Successor Administrative Agent, shall, with respect to such liens and security interests, constitute a reference to LCPI as collateral representative of the

Successor Administrative Agent; provided, that the parties hereto agree that LCPI’s role as such collateral representative shall impose no duties, obligations, or liabilities on LCPI, including, without limitation, any duty to take any type of direction regarding any action to be taken against such Collateral, whether such direction comes from the Successor Administrative Agent, the Required Lenders, or otherwise and LCPI shall have the full benefit of the protective provisions of Section 9 of the Amended Credit Agreement while serving in such capacity.

SECTION 1.10. Release. Each of the Borrower and the other Loan Parties hereby unconditionally and irrevocably waive all claims, suits, debts, liens, losses, causes of action, demands, rights, damages or costs, or expenses of any kind, character or nature whatsoever, known or unknown, fixed or contingent, which any of them may have or claim to have against LCPI (in its capacity as Administrative Agent, Swing Line Lender, a Lender, hedging counterparty, or any other capacity under the Loan Documents) or its agents, employees, officers, affiliates, directors, representatives, attorneys, successors and assigns (collectively, the “Released Parties”) to the extent arising at any time on or before the Effective Date out of or in connection with the Loan Documents (collectively, the “Claims”). Each of the Borrower and the Loan Parties further agree forever to refrain from commencing, instituting or prosecuting any lawsuit, action or other proceeding against any Released Parties with respect to such Claims and from exercising any rights of recoupment or setoff that it may have under a master netting agreement or otherwise against any obligation under the Loan Documents. Each of the Released Parties shall be a third party beneficiary of this Amendment. Notwithstanding anything herein to the contrary, in no event shall this Section 1.10 release or be deemed to release LCPI or any other Released Party from any claims, suits, debts, liens, losses, causes of actions, damages, costs or expenses of any kind, character or nature arising under this Amendment or the Assignment and Assumption.

SECTION 1.11. Effect of Agreement. The parties hereto acknowledge that, notwithstanding anything to the contrary in the Amended Credit Agreement, any other Loan Document or herein, LCPI, in its capacity as Administrative Agent or as Lender shall have no obligation to provide any further financial accommodations to or for the benefit of the Borrower, its Affiliates or any Loan Party pursuant to the Loan Documents.

SECTION 1.12. Limitation and Reservation of Rights. Each party hereto hereby confirms and agrees that (a) this Amendment (i) does not impose on LCPI affirmative obligations or indemnities not existing as of the date of its petition commencing its proceeding under chapter 11 of title 11 of the United States Code and that could give rise to administrative expense claims, and (ii) is not inconsistent with the terms of the 2007 Credit Agreement, (b) (i) LCPI’s rights to indemnification in its capacity as resigning Administrative Agent under Section 9.9 of the Amended Credit Agreement and (ii) any rights to indemnification of LCPI in its capacity as a Lender under any of the Loan Documents, shall continue in effect for the benefit of LCPI, its sub-agents and their respective affiliates, and (c) any rights to reimbursement or indemnification of LCPI in its capacity (i) as Pledgee arising under the Deed of Pledge of Registered Shares, dated July 27, 2007, by and between Syniverse Technologies, Inc., LCPI as Pledgee and Syniverse Technologies B.V. as the Company, including, without limitation, Section 15 thereof, (ii) in its capacity as Security Agent arising under the Share Pledge Agreement dated December 17, 2007 by and between Highwoods Corporation, LCPI as Security Agent and in the presence of Billing Services Group Luxembourg S.à.▇.▇. as the Company, including, without

limitation, Sections 13 and 18 thereof, and (iii) as Administrative Agent under the Share Mortgage, dated September 27, 2006, by and between Syniverse Technologies, Inc., and LCPI as Administrative Agent, including, without limitation, Section 10 thereof, shall continue in effect for the benefit of LCPI in such capacity.

SECTION 1.13. Appointment of Successor Agent. Effective as of the Effective Date, each of the undersigned Lenders hereby (a) appoints Bank of America as successor Administrative Agent under the Loan Documents and (b) acknowledges and agrees that Bank of America, as successor Administrative Agent under the Loan Documents is the beneficiary of Section 9 of the Amended Credit Agreement and all other indemnification and exculpatory provisions of the Loan Documents; provided, that under no circumstances does Bank of America assume, nor shall Bank of America be deemed to assume or be responsible for, (i) any obligations of the Administrative Agent under or pursuant to any Loan Document arising prior to the Effective Date or (ii) any claim of any nature arising at any time or from time to time against LCPI as Administrative Agent, Swing Line Lender or in any other capacity under or with respect to any Loan Documents or this Amendment or the transactions contemplated thereby or hereby.
