(b) For purposes of calculating the Total Leverage Ratio, the Fixed Charge Coverage Ratio, the Consolidated Secured Leverage Ratio and the First Lien Net Leverage Ratio, Specified Transactions (and the incurrence or repayment of any Indebtedness in connection therewith) that have been made (i) during the applicable Test Period and (ii) subsequent to such Test Period and prior to or simultaneously with the event for which the calculation of any such ratio is made shall be calculated on a pro forma basis assuming that all such Specified Transactions (and any increase or decrease in Consolidated EBITDA and the component financial definitions used therein attributable to any Specified Transaction) had occurred on the first day of the applicable

Test Period. If since the beginning of any applicable Test Period any Person that subsequently became a Restricted Subsidiary or was merged, amalgamated or consolidated with or into the Borrower or any of its Restricted Subsidiaries since the beginning of such Test Period shall have made any Specified Transaction that would have required adjustment pursuant to this Section 1.10, then the Total Leverage Ratio, the Fixed Charge Coverage Ratio, the Consolidated Secured Leverage Ratio and the First Lien Net Leverage Ratio shall be calculated to give pro forma effect thereto in accordance with this Section 1.10.

(c) Whenever pro forma effect is to be given to a Specified Transaction, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of Holdings and include, for the avoidance of doubt, the amount of cost savings, operating expense reductions and synergies projected by Holdings in good faith to be realized as a result of specified actions taken during such period (calculated on a pro forma basis as though such cost savings, operating expense reductions and synergies had been realized on the first day of such period as if such cost savings, operating expense reductions and synergies were realized during the entirety of such period) relating to such Specified Transaction, net of the amount of actual benefits realized during such period from such actions; provided, that (A) such amounts are reasonably identifiable and factually supportable in the good faith judgment of Holdings, (B) such actions are taken within eighteen (18) months after the date of such Specified Transaction, (C) any cost savings, operating expense reductions and synergies that are not actually realized during such period may no longer be added pursuant to this clause (c) after the end of the fourth full fiscal quarter ending after the date of such Specified Transaction, and (D) no amounts shall be added pursuant to this clause (c) to the extent duplicative of any amounts that are otherwise added back in computing Consolidated EBITDA, whether through a pro forma adjustment or otherwise, with respect to such period.

(d) In the event that Holdings or any Restricted Subsidiary incurs (including by assumption or guarantees) or repays (including by redemption, repayment, retirement or extinguishment) any Indebtedness included in the calculations of the Total Leverage Ratio, the Fixed Charge Coverage Ratio, the Consolidated Secured Leverage Ratio and the First Lien Net Leverage Ratio, as the case may be (in each case, other than Indebtedness incurred or repaid under any revolving credit facility in the ordinary course of business for working capital purposes), (i) during the applicable Test Period and (ii) subsequent to the end of the applicable Test Period and prior to or simultaneously with the event for

which the calculation of any such ratio is made, then the Total Leverage Ratio, the Fixed Charge Coverage Ratio, the Consolidated Secured Leverage Ratio and the First Lien Net Leverage Ratio shall be calculated giving pro forma effect to such incurrence or repayment of Indebtedness, to the extent required, as if the same had occurred on (A) the last day of the applicable Test Period in the case of the Total Leverage Ratio, the Consolidated Secured Leverage Ratio and the First Lien Net Leverage Ratio and (B) the first day of the applicable Test Period in the case of the Fixed Charge Coverage Ratio. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of the event for which the calculation of the Fixed Charge Coverage Ratio is made had been the applicable rate for the entire period (taking into account any hedging obligations applicable to such Indebtedness); provided, in the case of repayment of any Indebtedness, to the extent actual interest related thereto was included during all or any portion of the applicable Test Period, the actual interest may be used for the applicable portion of such Test Period. Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of Holdings to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a London interbank offered rate, or other rate, shall be determined to have been based upon the rate actually chose, or if none, then based upon such optional rate chosen as Holdings may designate.”.

“(a) The Borrower may at any time or from time to time after the Fifth Amendment Effective Date, by notice to the Administrative Agent (whereupon the Administrative Agent shall promptly deliver a copy to each of the Lenders), request one or more increases in the amount of the Revolving Credit Commitments on the same terms as the Revolving Credit Facility (a “Revolving Commitment Increase”) in an aggregate amount not to exceed $25,000,000 following the Fifth Amendment Effective Date, provided that (i) both at the time of any such request and upon the effectiveness of any Incremental Amendment referred to below, no Default or Event of Default shall exist, (ii) both at the time of any such request and upon the effectiveness of any Incremental Amendment referred to below, all of the representations and warranties of each Loan Party set forth in Article V and in each other Loan Document shall be true and correct in all material respects as of such time (except to the extent such representations and warranties expressly relate to an earlier date, in which case they shall be true and correct in all material respects as of such earlier date), and (iii) subject to compliance with the provisions set forth in the preceding clauses (i) and (ii), the Borrower may obtain additional Revolving Commitment Increases so long as the First Lien Net Leverage Ratio, determined on a Pro Forma Basis as of the date of the then most recently ended Test Period, in each case, as if such Revolving Commitment Increases were fully utilized and Revolving Loans available pursuant thereto had been outstanding on the last day of such Test Period, and without netting cash received from Borrowings under such Revolving Commitment Increases when calculating the First Lien Net Leverage Ratio, shall not exceed 2.25:1.00.

(c) Each Revolving Commitment Increase shall be in an aggregate principal amount that is not less than $5,000,000 and shall be in an increment of $1,000,000 (provided that such amount may be less if such amount represents all remaining availability under the limit set forth in the first sentence of Section 2.16(a)).

(d) Each notice from the Borrower pursuant to this Section 2.16 shall set forth the requested amount and proposed terms of the relevant Revolving Commitment Increases. Revolving Commitment Increases may be provided, by any existing Lender (but no existing Lender will have an obligation to make a portion of any Revolving Commitment Increase) or by any other bank or other financial institution (any such other bank or other financial institution being called an “Additional Lender”), provided that the Administrative Agent shall have consented (not to be unreasonably withheld) to such Lender’s or Additional

Lender’s providing such Revolving Commitment Increases if such consent would be required under Section 10.07(b) for an assignment of Revolving Credit Commitments to such Lender or Additional Lender. Commitments in respect Revolving Commitment Increases shall become Commitments (or in the case of a Revolving Commitment Increase to be provided by an existing Revolving Credit Lender, an increase in such Lender’s applicable Revolving Credit Commitment) under this Agreement pursuant to an amendment (an “Incremental Amendment”) to this Agreement and, as appropriate, the other Loan Documents, executed by the Borrower, each Lender agreeing to provide such Commitment, if any, each Additional Lender, if any, and the Administrative Agent. The Incremental Amendment may, without the consent of Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent and the Borrower, to effect the provisions of this Section 2.16. The effectiveness of any Incremental Amendment shall be subject to the satisfaction on the date thereof (each, an “Incremental Facility Closing Date”) of each of the conditions set forth in Section 4.02 (it being understood that all references to “the date of such Credit Extension” or similar language in such Section 4.02 shall be deemed to refer to the effective date of such Incremental Amendment) and such other conditions as the parties thereto shall agree. The Borrower will use the proceeds of the Revolving Commitment Increases for any purpose not prohibited by this Agreement. No Lender shall be obligated to provide any Revolving Commitment Increases unless it so agrees.

(e) Upon each increase in the Revolving Credit Commitments pursuant to this Section 2.16, (a) each Revolving Credit Lender immediately prior to such increase will automatically and without further act be deemed to have assigned to each Lender providing a portion of the Revolving Commitment Increase (each a “Revolving Commitment Increase Lender”), and each such Revolving Commitment Increase Lender will automatically and without further act be deemed to have assumed, a portion of such Revolving Credit Lender’s participations hereunder in outstanding Letters of Credit and Swing Line Loans such that, after giving effect to each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding (i) participations hereunder in Letters of Credit and (ii) participations hereunder in Swing Line Loans held by each Revolving Credit Lender (including each such Revolving Commitment Increase Lender) will equal the percentage of the aggregate Revolving Credit Commitments of all Revolving Credit Lenders represented by such Revolving Credit Lender’s Revolving Credit Commitment and (b) if, on the date of such increase, there are any Revolving Credit Loans under the applicable Facility outstanding, such Revolving Credit Loans shall on or prior to the effectiveness of such Revolving Commitment Increase be prepaid from the proceeds of additional Revolving Credit Loans made hereunder (reflecting such increase in Revolving Credit Commitments), which prepayment shall be accompanied by accrued interest on the Revolving Credit Loans being prepaid and any costs incurred by any Lender in accordance with Section 3.05. The Administrative Agent and the

Lenders hereby agree that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence.

(f) This Section 2.16 shall supersede any provisions in Section 2.13 or 10.01 to the contrary.”

“Section 3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund LIBO Rate Loans (whether denominated in Dollars or Euros), then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue LIBO Rate Loans in the affected currency or currencies shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (x) the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or (I) if applicable and such Loans are denominated in Dollars, convert all of such Lender’s LIBO Rate Loans to Base Rate Loans (the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the LIBO Rate component of the Base Rate) or (II) if applicable and such Loans are denominated in Euros, to the extent the applicable Borrower and all Appropriate Lenders agree, convert such Loans to Loans bearing interest at an alternative rate mutually acceptable to the Borrower and all of the Appropriate Lenders, in each case, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such LIBO Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such LIBO Rate Loans and (y) if such notice asserts the illegality of such Lender determining or charging interest rates based upon the LIBO Rate, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender without reference to the LIBO Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the LIBO Rate. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted and all amounts due, if any, in connection with such prepayment or conversion under Section 3.05. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.”.

(n) Amendment to Section 3.03 (Inability to Determine Rates). Section 3.03 of the Credit Agreement is hereby amended and restated in its entirety as follows:

“Section 3.03 Inability to Determine Rates. If the Required Lenders determine that for any reason adequate and reasonable means do not exist for determining the applicable LIBO Rate for any requested Interest Period with respect to a proposed LIBO Rate Loan, or that the LIBO Rate for any requested Interest Period with respect to a proposed LIBO Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, or that Dollar deposits or Euro deposits are not being offered to banks in the London interbank eurodollar, or other applicable, market for the applicable amount and the Interest Period of such LIBO Rate Loan, the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain LIBO Rate Loans shall be suspended until the Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of such LIBO Rate Loans or, failing that, will be deemed to have converted such request, if applicable, into a request for a Borrowing of Base Rate Loans in the amount specified therein (or, in the case of a pending request for a Loan denominated in Euros, the Borrower and the Lenders may establish a mutually acceptable alternative rate).”.

(o) Amendment to Section 3.04 (Increased Cost and Reduced Return; Capital Adequacy; Reserves on LIBO Rate Loans). Section 3.04 of the Credit Agreement is hereby amended by (1) inserting a new clause (c) as follows:

After giving effect to each and all parts of the Fifth Amendment, each Guarantor reaffirms each Lien granted by it to the Collateral Agent for the benefit of the Secured Parties under each of the Loan Documents to which it is a party, which Liens were always intended by the parties to secure the Obligations as amended from time to time (including any increases thereof) and shall continue in full force and effect during the term of the Credit Agreement as amended by each and all parts of the Fifth Amendment, and shall continue to secure the Obligations (after giving effect to each and all parts of the Fifth Amendment and including any increase of such Obligations), in each case, on and subject to the terms and conditions set forth in the Credit Agreement, as amended by each and all parts of the Fifth Amendment, and the other Loan Documents.

Notwithstanding anything to the contrary set out in this Consent, until such time as all required statutory whitewash processes under Section 76(10) of the Companies Act, Chapter 50 of Singapore have been completed, each Singapore Subsidiary and each Hong Kong Subsidiary executing this Consent as a Guarantor hereby consents, acknowledges, agrees and reaffirms as to the aforesaid matters other than in respect of the 2013 Senior Secured Notes.

Nothing in this Consent shall create or otherwise give rise to any right to consent on the part of the Guarantors to the extent not required by the express terms of the Loan Documents.

This Consent is a Loan Document and shall be governed by, and construed and interpreted in accordance with, the law of the state of New York (without regard to conflict of laws principles other than Sections 5-1401 and 5-1402 of the New York General Obligations Law).
