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 12:00 p.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
the applicable Interest Period with respect to each Eurodollar Rate Loan (ii) on
the last Business Day of each calendar quarter with respect to Base Rate ; 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 2%. 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) 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 125 High Street, Oliver Street 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. Notwithstanding any provision of
this Agreement to the contrary, the Borrower shall not reimburse the Lender for
any U.S. federal withholding taxes imposed under Sections 1471 through 1474 of
the Internal Revenue Code of 1986, as of the date of this Agreement (and any
amended or successor version that is substantively comparable and not materially
more onerous to comply with), and any current or future regulations (whether
temporary or proposed) that are issued thereunder or official governmental
interpretations thereof.

(f) 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.

various factors including HSBC Bank USA's costs and desired return, general
economic conditions and other factors, and is used as a reference point for

change.

prepayment of any Eurodollar Rate Loan on a day other than the last day of the
Interest Period therefor (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise); or (ii) any failure by the Borrower to prepay,

Any event or condition that constitutes an Event of Default or that, with the
giving of any notice, the passage of time, or both, would be an Event of
Default.
Dollar or $:
The lawful currency of the United States of America.
Eurodollar Rate:

The rate per annum equal to (i) the British Bankers Association LIBOR Rate
("BBA LIBOR"), as published by Reuters (or such other commercially available

to the commencement of such Interest Period, for Dollar deposits (for delivery
on the first day of such Interest Period) with a term equivalent to such
Interest Period or, (ii) if such rate is not available at such time for any
reason, the rate per annum determined by the Lender to be the rate at which
deposits in Dollars for delivery on the first day of such Interest Period in
same day funds in the approximate amount of the Eurodollar Rate Loan being made,
continued or converted and with a term equivalent to such Interest Period would
be offered by Bank of America's London Branch to major banks in the London
interbank eurodollar market at their request at approximately 11:00 a.m. (London
time) two Business Days prior to the commencement of such Interest Period.

--------------------------------------------------------------------------------

decimal, carried out to five decimal places) in effect on such day applicable to
the Lender under regulations issued from time to time by the Board of Governors
of the Federal Reserve System for determining the maximum reserve requirement
(including any emergency, supplemental or other marginal reserve requirement)
with respect to Eurocurrency funding (currently referred to as "Eurocurrency
liabilities"). The Adjusted Eurodollar Rate for each outstanding Eurodollar Rate

such day shall be such rate on such transactions on the next preceding Business
Day as so published on the next succeeding Business Day, and (b) if no such rate
is so published on such next succeeding Business Day, the Federal Funds Rate for

as determined by the Lender.
