Can a conditional gift deed be revoked?

My late grandfather (the donor) donated a piece of land to a education society (donee) through conditional gift deed with the first condition that the donor will be the permanent member of the educational society and on his death his nominee, second condition the land should be used for education purpose and nothing else, the school should be named specifically after the donor's name. The gift deed ends with the term that breach of any terms and conditions by the donee in future the donor reserves the right to revoke the gift deed. The definition of donor is specified as his legal heirs, administrators or nominee in the said gift deed. After my grandfather's death my father was taken as a member of the said educ. society and not as permanent member. My father recently expired and the said donee is denying to take me as permanent member, changed the school name, using the said premises for marriage and politics. In the above condition do I have a right to revoke the deed as it's clear breach of the conditions mentioned in the gift deed. The gift deed was registered and accepted by donee. What is the remedy.
