                        PREFERRED STOCK SALE AGREEMENT
                        ------------------------------


         THIS PREFERRED STOCK SALE AGREEMENT (this "Agreement"), dated as of
April 3, 1997, by and among Sygnet Redemption Corp., an Ohio corporation (the
"Company"), and each of the entities set forth on the signature page of this
Agreement (each a "Seller" and collectively the "Sellers"), and agreed and
consented to by Sygnet Wireless, Inc., an Ohio corporation ("Wireless").

         WHEREAS:

         A.   The Company is a wholly owned subsidiary of Wireless;

         B.   Pursuant to the Preferred Stock and Common Stock Warrant Purchase
Agreement between Wireless and Toronto Dominion Investments, Inc. ("TDI"),
dated as of October 9, 1996 (the "Purchase Agreement"), Wireless sold 200,000
shares of its Series A Senior Cumulative Nonvoting Preferred Stock (the
"Shares") and rights to receive certain warrants to purchase shares of its
Class A Common Stock (the "Warrant Rights") to TDI. Subsequently, pursuant to
letter agreements dated October 18, 1996, and November 27, 1996, respectively,
TDI sold certain of the Shares and the proportionate divided interests in the
Warrant Rights associated with such Shares to each of the other Sellers (such
interests referred to in this Agreement as the "Warrant Rights associated
therewith");

         C.   Under its articles of incorporation, Wireless has the right to
redeem the Shares at any time;

         D.   The Indenture (the "Indenture") relating to certain outstanding
11 1/2 % Senior Notes issued by Wireless generally limits the payments which may
be made by Wireless to redeem the Shares, but permits Wireless to redeem the
Shares with the proceeds of a substantially concurrent sale of its capital
stock or to use up to $10 million for investment in an Unrestricted Subsidiary
(as defined in the Indenture) which may be used by such Subsidiary, among
other things, to purchase Shares;

         E.   Wireless has chosen to invest $10,000,000 in the Company, and has
designated the Company as an Unrestricted Subsidiary; and

         F.   Each Seller wishes to sell and the Company wishes to purchase,
upon the terms and conditions set forth in this Agreement, the number of
Shares set forth below such Seller's name on the signature page of this
Agreement.
