Dear Sir/Madam:

This revised letter constitutes our agreement with respect to compensation to be paid to PNC Global Investment Servicing (U.S.) Inc. (formerly, PFPC Inc.) (“PNC”) under the terms of a Transfer Agency Services Agreement dated February 10, 1999 between BlackRock Liquidity Funds (formerly, BlackRock Provident Institutional Funds) (“you” or the “Fund”) and PNC, as amended or amended and restated from time to time (the “Agreement”) for services provided on behalf of each of the Fund’s investment portfolios (each a “Portfolio”). Pursuant to the Agreement, and in consideration of the services to be provided to each Portfolio, the Fund will pay PFPC certain fees and reimburse PFPC for its out-of-pocket and other expenses incurred on its behalf, as set forth below. This letter supercedes all previous fee agreements with respect to the fees set forth herein.

1) Account Fee:

Open Account	$16.00 per account per annum
Closed Account:	$ 1.50 per account per annum

Fees shall be calculated and paid monthly based on one-twelfth (1/12th) of the annual fee. A closed account is defined as having a zero balance with no dividend payable. Closed accounts are purged annually after year-end tax reporting.

2) Annual Base Fee:

The annual base fee shall be $1,750,000, excluding out-of-pocket expenses, for the first 40 classes plus $50,000 for each additional class beyond the first 40. The monthly aggregate base fee will be allocated pro-rata to each class based on average net assets.

3) Transaction Charges:

Wires (receipt/disbursement;
international/domestic) $ 4.00 per wire

The fee for the period from the date hereof until the end of the year shall be prorated according to the proportion which such period bears to the full annual period.

Each party hereto is represented by counsel, and no presumptions shall arise favoring any party by virtue of the authorship of any provision of this letter.
