@medicalresearch.org＞ Subject: Due Date Date: February 20 Dear Dr. Ericsson, Once again, I would like to congratulate your institute on being selected as a recipient of the grant from Sullivan Charities. We are especially pleased that you will be focusing your research on family medicine and trust that your final report, "Treatment for Hepatitis B" will be of great value to the medical field. I want to point out that there was a mistake in the official grant letter dated February 5. I incorrectly specified November 30 as the due date for submission of the final report. The correct due date is November 15. Kindly make changes on page 2 of both grant letters. Also, I want to remind you that you must submit a formal letter of acceptance to us no later than March 1. As I mentioned earlier, the grant will be divided into four installments. If you accept our offer, the first quarterly payment will be credited to your bank account by April 1. Please inform. us of your bank account number as well.
