Box 7777 San Mateo, CA 94403-7777 REMINDER: SPECIAL MEETING OF SHAREHOLDERS TO BE HELD JUNE 5, 1998 Dear Shareholder: We have not yet received your vote for the upcoming Special Meeting of Shareholders scheduled to be held June 5, 1998. It is critical that you vote your proxy. All votes are vital no matter how many shares you hold and YOUR SHARES CANNOT BE REPRESENTED UNLESS WE RECEIVE VOTING INSTRUCTIONS FROM YOU! The Reorganization proposal requires the affirmative vote of two-thirds of the outstanding shares of the Fund, making it critical that all shareholders participate! Thus far, we have received voting instructions from approximately 50% of the outstanding shares of which an overwhelming 90% are voting in favor of the Reorganization. In order for your shares to be represented at the meeting, we must receive your vote on or before Friday, JUNE 5, 1998. The meeting has been called in order to consider and approve a Reorganization which would result in an exchange of the assets of Franklin Principal Maturity Trust for Class I shares of Franklin Income Fund. Franklin Income Fund is a series of Franklin Custodian Funds, Inc., an open-end investment company also managed by Franklin Advisers, Inc. If the proposal is approved, on the date of the Reorganization, you will receive Class I shares of the Income Series equal to the value of your investment in the Fund on that date (at net asset value rather than the New York Stock Exchange price). Please see the proxy statement which was previously mailed to you for further information. For your convenience, we have established three easy methods by which to register your vote: 1. BY PHONE: Please call SHAREHOLDER COMMUNICATIONS CORPORATION toll free at 1-800-733-8481, EXTENSION "480." Operators will be available to take your vote Monday thru Friday between the hours of 9:00 a.m. and 11:00 p.m. and Saturday from 12:00 p.m. to 6:00 p.m. Eastern Time. 2. BY FAX: Fax your executed proxy to us toll free at 1-800-733-1885, anytime. 3. BY MAIL: Return your executed proxy in the enclosed postage paid envelope. Please utilize this option only if methods 1 and 2 are both unavailable, as we may not receive your proxy by mail by the June 5, 1998 meeting. If you have any questions regarding the proxy statement or need assistance executing your vote, please call SHAREHOLDER COMMUNICATIONS CORPORATION at the above-mentioned number. We urge you to act promptly so that your vote may be received before the meeting and further proxy solicitation expenses will not be incurred. Thank you for your consideration of this matter.
