                                AMENDMENT TO THE
                        INFINITY BROADCASTING CORPORATION
                                STOCK OPTION PLAN

         The Plan is amended in the manner set forth below:

         i.  Section  2(a) of the  Plan is  amended  to  reflect  the  Company's
three-for-two  stock split in the form of a stock  dividend,  effective  May 19,
1995, so that the first sentence thereof reads in its entirety as follows:

         "Subject to adjustment  as provided in Section 9, the aggregate  number
         of shares of the Class A Common Stock of the Company ("Class A Shares")
         to be delivered  upon  exercise of all options  granted  under the Plan
         shall be 6,996,525  and the  aggregate  number of shares of the Class B
         Common Stock of the Company ("Class B Shares" and together with Class A
         Shares,  "Shares") to be delivered upon exercise of all options granted
         under the Plan shall be 1,181,250."

Section 2(a) is further amended to delete the last sentence thereof.

         ii.  Section  7(c) of the Plan is  deleted  in its  entirety  and a new
Section 7(c) is added in lieu thereof, to read as follows:

         "(c)  NONTRANSFERABILITY OF AWARDS. An option shall not be transferable
         otherwise  than by will or by the laws of descent and  distribution  or
         pursuant to a qualified domestic relations order as defined by the Code
         or Title I of the Employee  Retirement  Income Security Act of 1974, as
         amended  (or  the  rules  thereunder),  or to a  Permitted  Transferee;
         PROVIDED that no otherwise permitted transfer shall be effective unless
         the deceased Optionee's beneficiary or the representative of his estate
         or the Permitted  Transferee  acknowledges and agrees in writing,  in a
         form  reasonably  acceptable  to  the  Company,  to  be  bound  by  the
         provisions of the Plan and the Option  Agreement  covering such Options
         as if such  beneficiary  or estate were the  Optionee.  All rights with
         respect  to  Options  granted  to an  Optionee  under the Plan shall be
         exercisable during his lifetime by such Optionee (or, if applicable,  a
         Permitted  Transferee).  Following an Optionee's death, all rights with
         respect to Options that were exercisable at the time of such Optionee's
         death and have not  terminated  shall be  exercised  by his  designated
         beneficiary or estate (or, if applicable,  a Permitted Transferee).  As
         used in this Section 7(c), a Permitted  Transferee shall be a member of
         the Optionee's  family or a trust or similar vehicle for the benefit of
         such family members to whom or to which the Administrator  shall permit
         (on such terms and  conditions  as it shall  establish) an Option to be
         transferred."
