RE: OPTION AND LICENSE AGREEMENT BETWEEN CORIXA AND PMC - ▇▇▇▇ ▇▇▇▇▇▇▇▇
Dear ▇▇▇▇:
I have been informed that the LeIF sample has been received by PMC on March 4,
1997, which date will be the Delivery Date in accordance with Section 1.1.(j) of
the above-mentioned Agreement, provided said sample meets Material
Specifications as described in Schedule C to the Agreement.
Subject to such proviso, the cut-off date under Section 2.2.1. thereof will be
September 3, 1997.
By such date, PMC will have to exercise at least one (1) Option with respect to
at least one (1) Field of Use if PMC wants to maintain its rights under the
Agreement.
Please note that Section 14.1 of the Agreement has been mixed up by your outside
counsel (word processing incident?). Such Section should now read:
"14.1. Automatic Termination.
Unless terminated earlier pursuant to this Article 14 or in accordance
with Article 16 hereof, the Agreement shall automatically terminate
effective September 3, 1997, unless on or before September 2, 1997, PMC
exercises at least one (1) Option in one (1) Field of Use in accordance
with Sections 2.2.1. and 2.2.4. hereof. Any termination of the Research
Program shall also terminate this Agreement as a whole."
If you agree with the foregoing, please have the two original copies of this
letter duly signed for CORIXA in the space herebelow provided for to that
effect.

Such letter will be an amendment to the Agreement in accordance with its Section
19.4; terms and conditions of the Agreement not expressly amended hereby will
remain unchanged.
With best regards,
Sincerely yours
/s/ HERVE TAINTURIER
