               Re: Term Loan Facility

Ladies and Gentlemen:

HSBC BANK USA, National Association. (the “Lender”) is pleased to make available to PAREXEL INTERNATIONAL CORPORATION, a Massachusetts corporation (the “Borrower”), a term loan on the terms and subject to the conditions set forth below. Terms not defined herein have the meanings assigned to them in Exhibit A hereto.

1.

The Facility.

	(a)		The Term Loan. Subject to the terms and conditions set forth herein, the Lender agrees to make a single loan to the Borrower on the Closing Date in an aggregate principal amount equal to $25,000,000 (the “Term Loan”). Amounts borrowed under this Paragraph 1(a) and repaid or prepaid may not be reborrowed.
	(b)		Borrowings, Conversions, Continuations. The Borrower may request that the Term Loan or, subject to the terms and conditions set forth herein, any portion thereof be (i) made as or converted to a Base Rate Loan by irrevocable notice to be received by the Lender not later than 11:00 a.m. on the Business Day of the borrowing or conversion, or (ii) made or continued as, or converted to, a Eurodollar Rate Loan by irrevocable notice to be received by the Lender not later than 11:00 a.m. three Business Days (or in the case of the initial Term Loan to be made on the Closing Date, such shorter period as may be agreed to by the Lender) prior to the Business Day of the borrowing, continuation or conversion. If the Borrower fails to give a notice of conversion or continuation prior to the end of any Interest Period in respect of any Eurodollar Rate Loan, the Borrower shall be deemed to have requested such Eurodollar Rate Loan to be converted to a Base Rate Loan on the last day of the applicable Interest Period. If the Borrower requests that any portion of the Term Loan be continued as or converted to a Eurodollar Rate Loan, but fails to specify an Interest Period with respect thereto, the Borrower shall be deemed to have selected an Interest Period of one month. Notices pursuant to this Paragraph 1(b) may be given by telephone if promptly confirmed in writing by a Responsible Officer.
			Each Eurodollar Rate Loan shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Each Base Rate Loan shall be in a minimum principal amount of $500,000. There shall not be more than 3 different Interest Periods in effect at any time.

	(c)		Interest. At the option of the Borrower, the Term Loan shall bear interest at a rate per annum equal to (i) the Eurodollar Rate plus the Applicable Margin; or (ii) the Base Rate plus the Applicable Margin. All computations of interest for Base Rate Loans shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other interest hereunder shall be calculated on the basis of a year of 360 days and actual days elapsed.
			The Borrower promises to pay interest and fees (i) on the last Business Day of each calendar month commencing January 31, 2011 and each calendar month thereafter; and (iii) on the Maturity Date. If the time for any payment is extended by operation of law or otherwise, interest shall continue to accrue for such extended period.
			After the date any principal amount of the Term Loan is due and payable (whether on the Maturity Date, upon acceleration or otherwise), or after any other monetary obligation hereunder shall have become due and payable (in each case without regard to any applicable grace periods), the Borrower shall pay interest (after as well as before judgment) on such amounts at a rate per annum equal to the Base Rate plus the Applicable Margin plus 5%. Accrued and unpaid interest on past due amounts shall be payable on demand.
			In no case shall interest hereunder exceed the amount that the Lender may charge or collect under applicable law.
	(d)		Evidence of Loans. The Term Loan and all payments thereon shall be evidenced by the Lender’s loan accounts and records; provided, however, that upon the request of the Lender, the Term Loan may be evidenced by a promissory note in a form reasonably acceptable to the Lender in addition to such loan accounts and records. Such loan accounts, records and promissory note, if any, shall be conclusive absent manifest error of the amount of the Term Loan and payments thereon. Any failure to record the Term Loan or payment thereon or any error in doing so shall not limit or otherwise affect the obligation of the Borrower to pay any amount owing with respect to the Term Loan.
	(e)		Closing Fee. The Borrower agrees to pay to the Lender a closing fee of $25,000 (the “Closing Fee”). The Closing Fee shall be due and payable on the Closing Date and, upon payment, shall not be refundable for any reason whatsoever.
	(f)		Repayment. (i) The Borrower hereby promises, absolutely and unconditionally, to pay the aggregate principal amount of the Term Loan then outstanding on the Maturity Date. The Borrower shall make all payments required hereunder not later than 2:00 p.m. on the date of payment in same day funds in Dollars at the office of the Lender located at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇ Tower, 16th Floor, Boston, Massachusetts 02110 or such other address as the Lender may from time to time designate in writing.

(ii)

All payments by the Borrower to the Lender hereunder shall be made to the Lender in full without set-off or counterclaim and free and clear of and exempt from, and without deduction or withholding for or on account of, any present or future taxes, levies, imposts, duties or charges of whatsoever nature imposed by any government or any political subdivision or taxing authority thereof unless the Borrower is required to deduct or withhold such amounts by law. If the Borrower is required to deduct or withhold taxes by law, the Borrower shall reimburse the Lender for any taxes imposed on or withheld from such payments (other than taxes imposed on the Lender’s income, franchise taxes imposed on the Lender, or branch profits taxes or similar taxes imposed on the Lender, by the jurisdiction under the laws of which the Lender is organized or any political subdivision thereof or in which its principal or lending office is located or by any jurisdiction as a result of a present or former connection between the Lender and such jurisdiction, other than any such connection arising solely as a result of this Agreement). On or prior to the Closing Date, the Lender shall deliver to the Borrower, a duly executed and properly completed copy of IRS Form W-9 (or applicable successor form) establishing an exemption from United States federal backup withholding tax. Borrower shall not reimburse the Lender for any withholding taxes resulting from Lender’s failure to deliver such form. No assignee or participant shall be entitled to reimbursement for taxes hereunder or reimbursement or payment of any costs, losses or payments under Paragraph 5(d) hereof, to the extent that the assignor or grantor of participation rights, as applicable, was not entitled to such reimbursement or payment at the time of such assignment or grant of participation. Any assignee or participant shall provide the Borrower with a duly completed and properly completed IRS Form W-9 or appropriate IRS Form W-8, as applicable.

(g)

Prepayments. The Borrower may, upon three Business Days’ notice, in the case of Eurodollar Rate Loans, and upon same-day notice in the case of Base Rate Loans, prepay Base Rate Loans on any Business Day; provided that the Borrower pays all Breakage Costs (if any) associated with such prepayment on the date of such prepayment. Prepayments of Eurodollar Rate Loans must be accompanied by a payment of interest on the amount so prepaid. Prepayments of Eurodollar Rate Loans must be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Prepayments of Base Rate Loans must be in a principal amount of at least $500,000 or, if less, the entire principal amount thereof then outstanding.
