PURCHASE AGREEMENT
Credit Suisse Institutional Fund, Inc. (the "Fund"), a corporation
organized under the laws of the State of Maryland, with respect to the Cash
Reserve Portfolio, the Global Telecommunications Portfolio, the High Yield
Portfolio, the Long-Short Market Neutral Portfolio and the Major Foreign Markets
Portfolio (the "Portfolios"), and Credit Suisse Asset Management, LLC ("CSAM")
hereby agree as follows:
1. The Fund offers CSAM and CSAM hereby purchases one share of common stock
of each of the Portfolios, having a par value of $.001 per share, at a price of
$10.00 per Share, in the case of each Portfolio other than the Cash Reserve
Portfolio, and at a price of $1.00 per Share in the case of the Cash Reserve
Portfolio (each an "Initial Share"). CSAM hereby acknowledges receipt of
certificates representing each Initial Share and the Fund hereby acknowledges
receipt from CSAM of $41.00 in full payment for the Initial Shares.
2. CSAM represents and warrants to the Fund that the Initial Shares are
being acquired for investment purposes and not for the purpose of distribution.
3. CSAM agrees that if any holder of the Initial Shares redeems the Initial
Shares in a Portfolio before five years after the date upon which the Portfolio
commences its investment activities, the redemption proceeds will be reduced by
the amount of unamortized organizational expenses in the same proportion as the
number of Initial Shares being redeemed bears to the number of Initial Shares
outstanding at the time of redemption. The parties hereby acknowledge that any
shares acquired by CSAM other than the Initial Shares have not been acquired to
fulfill the requirements of Section 14 of the Investment Company Act of 1940, as
amended, and, if redeemed, their redemption proceeds will not be subject to
reduction based on the unamortized organizational expenses of the Portfolios.
