Dear Mr. Miller:

This letter serves as notice that MacroGenics is applying its right to obtain two months of rent abatement under Section 13 of the amended lease to the months of March and April of 2006. As a consequence, no rent payment will be due from MacroGenics for those two months.

If you have any questions regarding this matter, please do not hesitate to contact me at 301-354-0686.

Sincerely,
