 The parties hereto therefore

that is defined in the Margin Loan Agreement has the meaning assigned to such term in the Margin Loan Agreement. Each reference to “hereof”, “hereunder”, “herein” and “hereby” and each other similar reference
and each reference to “this Agreement” and each other similar reference contained in the Margin Loan Agreement shall, after this Amendment becomes effective, refer to the Margin Loan Agreement as amended hereby. For the avoidance of doubt,
after the Amendment No. 1 Effective Date (as defined below), any references to “date hereof,” or “date of this Agreement,” in the Margin Loan Agreement, shall continue to refer to December 21, 2012. 

SECTION 2. Amendments to Margin Loan Agreement. Effective on and as of the Amendment No. 1 Effective Date: 

 

	 	(a)	Section 1.01 of the Margin Loan Agreement is hereby amended by

	 	(ii)	amending and restating the definitions of the following terms to read as follows: 


“Adjusted Initial Basket” means, as of the Amendment No. 1 Effective Date, a number of TGP Shares and TOO Shares
equal to the Initial Basket (after giving effect to Amendment No. 1), which number shall from time to time be (x) reduced by the number of TGP Shares or TOO Shares, as the case may be, released pursuant to Section 2.10(b) or
Section 2.10(c) and (y) increased by the number of any additional TGP Shares or TOO Shares, as the case may be, pledged by Borrower pursuant to Section 2.10(c) that constitute Eligible Collateral; provided that neither the
number of TGP Shares nor the number of TOO Shares in the Adjusted Initial Basket may be so increased to exceed the number of TGP Shares or TOO Shares, respectively, in the Initial Basket (after giving effect to Amendment No. 1). 

  
 1 








 “Commitment” means, with respect to each Lender, the commitment of such
Lender to make the Advances hereunder, as reduced or increased from time to time pursuant to assignments by or to such Lender pursuant to Section 9.09. The amount of each Lender’s Commitment is such Lender’s Original Commitment plus
such Lender’s Incremental Commitment, or is the amount set forth opposite such Lender’s name on the signature page in the Assignment and Assumption pursuant to which such Lender shall have assumed its Commitment, as applicable. 

“Initial Basket” means (a) as of any date prior to the Amendment No. 1 Effective Date, the number of TGP
Shares and the number of TOO Shares constituting Eligible Collateral immediately prior to the first Borrowing hereunder and (b) as of any date from and after the Amendment No. 1 Effective Date, the number of TGP Shares and the number of
TOO Shares constituting Eligible Collateral on the Amendment No. 1 Effective Date after giving effect to the additional pledge referred to in Section 4(b) of Amendment No. 1. 

“Initial Share Collateral Value” means (a) as of any date prior to the Amendment No. 1 Effective Date, the
Share Collateral Value as of December 21, 2012 and (b) as of any date from and after the Amendment No. 1 Effective Date, the Share Collateral Value as of the Amendment No. 1 Effective Date after giving effect to the additional

 (c) Section 2.08(b) is hereby amended and restated in its entirety to read as follows: 

(b) Borrower shall pay to Administrative Agent for the account of each Lender a commitment fee (the “Commitment
Fee”) (i) on the average daily undrawn portion of the Original Commitment for such Lender during the Commitment Fee Period at a rate equal to the Original Commitment Fee Rate, calculated on the basis of the actual days elapsed and
a year of 360 days and payable in arrears on each day the interest is due (or would be due if Borrowings were outstanding) pursuant to Section 2.07 and (ii) on the average daily undrawn portion of the Incremental Commitment for such Lender
during the Commitment Fee Period at a rate equal to the Incremental Commitment Fee Rate, calculated on the basis of the actual days elapsed and a year of 360 days and payable in arrears on each day the interest is due (or would be due if Borrowings
were outstanding) pursuant to Section 2.07. For purposes of determining whether undrawn Commitments at any time are attributable to the Original Commitments or the Incremental Commitments, it shall be assumed that all Original Commitments are
fully drawn before any Incremental Commitments are drawn. The Commitment Fee shall accrue at all times during the Commitment Fee Period (but not, for the avoidance of doubt, during any Commitment Unavailability Period), including at any time during

 “Incremental Commitment Fee Rate” means 1.25% per annum;
provided that if the average daily aggregate principal amount of all Advances outstanding hereunder over the period from the Amendment No. 1 Effective Date to the first anniversary of the Amendment No. 1 Effective Date is equal to

immediately available funds to the account of Administrative Agent most recently designated by it for such purpose by notice to the Lenders an amount equal to such Lender’s Excess Incremental Commitment Fee Amount, and Administrative Agent will
make all funds so received available to Borrower by crediting the amounts so received, in like funds as received by Administrative Agent, to the Funding Account. “Excess Incremental Commitment Fee Amount” means,
with respect to any Lender, the excess of (x) the aggregate amount of Commitment Fee actually paid to such Lender (or to Administrative Agent for the account of such Lender) prior to the first anniversary of the Amendment No. 1 Effective
Date over (y) the amount of Commitment Fee that would have been paid to such Lender (or to Administrative Agent for the account of such Lender) prior to such first anniversary if the Incremental Commitment Fee Rate had been 0.75% per annum
at all times from the Amendment No. 1 Effective Date, as determined by the Calculation Agent.
