Holders of H.A.A. season tickets will have their choice of three price rates when they exchange their coupons for scats to Crimson basketball games at the Boston Garden, ticket manager Frank O. Lunden announced yesterday.

Sixty cents plus the coupon in the H.A.A. ticket booklet will purchase a $1.25 seat, $1 plus the coupon will be needed for a $2 seat, and $1.25 and the coupon nets a $2.75 location, Lunden continued.

The H.A.A. official emphasized the fact that such exchanges will be transacted only through the Association's offices at Quincy Street. The Garden will not honor season ticket coupons. Purchases for weekday games con be made until 5 o'clock on game days, while locations for Saturday night contests at the special rate can be obtained before noon on Saturdays.

For basketball games at the Indoor Athletic Building, such as the engagement tonight between the Varsity and M.I.T., the season ticket coupon is the admission fee. Non-ticket holders, as always, will be charged.

The first basketball game scheduled for the Garden will be next Tuesday's Varsity-Holy Cross encounter. Arrangements for the Crimson hockey games at the Garden will be announced at a later date.
