Ladies and Gentlemen:

         The undersigned, Sygnet Wireless, Inc. (the "COMPANY"), an Ohio
corporation, hereby agrees with you (the "INVESTOR") as follows:

         1. AUTHORIZATION OF SECURITIES. The Company has authorized the issue
and sale of an aggregate of 200,000 shares of its Series A Senior Cumulative
Nonvoting Preferred Stock (the "PREFERRED STOCK"), having the rights,
preferences and privileges set forth in the Company's Certificate of Amendment
to Articles of Incorporation (hereinafter referred to as the "CERTIFICATE"), a
copy of which is attached hereto as Annex A. The Company has also authorized
the issue and sale of warrants (the "WARRANTS") to purchase such percentages
as are set forth in Section 2(b) of the shares of the Company's Class A Common
Stock, $0.01 par value per share (the "CLASS A COMMON STOCK"), calculated on a
fully diluted basis as set forth in, and with the rights, preferences and
privileges set forth in, the form warrant certificate attached hereto as Annex
B (the "WARRANT CERTIFICATE"). The Preferred Stock, Warrants and Class A
Common Stock issuable upon exercise of the Warrants are sometimes referred to
collectively herein as the "SECURITIES".

         2. SALE AND PURCHASE OF PREFERRED STOCK AND WARRANTS.

               (a)   Upon the terms and subject to the conditions herein
contained, (i) the Company agrees to sell to Investor, and Investor agrees to
purchase from the Company, at the Closing (as hereinafter defined) on the
Closing Date (as hereinafter defined), 200,000 shares of Preferred Stock, (ii)
the Company agrees to issue to Investor Warrants to purchase shares of Class A
Common Stock at the times and in the percentages set forth herein, and (iii)
Investor shall pay to the Company twenty million dollars ($20,000,000) (the
"REQUIRED PAYMENT") in immediately available funds.



                                      -1-

                                                                        Page 2





               (b)   So long as any shares of Preferred Stock remain
outstanding, (i) upon the nine-month anniversary of the Closing Date, a
Warrant to purchase Class A Common Stock representing, in the aggregate, one
percent (1%) of the then-outstanding Class A and Class B Common Stock
combined, and (ii) within five (5) Business Days of each fiscal quarter end
thereafter, a Warrant to purchase Class A Common Stock representing three
eighths of a percent (3/8%) of the then-outstanding Class A and Class B Common
Stock combined as of such quarter end, in each case calculated on a fully
diluted basis (including in such calculation the maximum number of shares of
Class A and Class B Common Stock issuable upon conversion, exchange or
exercise of (A) all then-outstanding securities (whether debt or equity) of
the Company convertible or exchangeable for Class A or Class B Common Stock
and (B) all then-outstanding warrants and options to purchase Class A or Class
B Common Stock, but excluding shares underlying Warrants issued pursuant to
this Agreement), will be issued to Investor (or such permitted transferees of
Investor's rights to such Warrants as Investor shall designate in accordance
with this Agreement) as additional consideration for the purchase and sale
contemplated hereby; provided, that the percentage of then-outstanding shares
of Class A and Class B Common Stock purchasable pursuant to the Warrant
issuable on the nine-month anniversary of the Closing Date shall be adjusted
pro rata to reflect the number of shares of Preferred Stock outstanding if
shares of Preferred Stock are redeemed pursuant to an optional redemption (as
provided in the Certificate) by the Company within the six-month period
immediately following the Closing Date.

         3.    CLOSING.
                    
               3.1   CLOSING. The closing of the sale to and purchase by
Investor of the Preferred Stock and Warrants (the "CLOSING") shall occur at
the offices of Bryan Cave LLP, 700 Thirteenth Street, N.W., Washington, D.C.
20005, at the hour of 10:00 A.M., Eastern daylight time, on October 9, 1996 or
at such different time or day as Investor and the Company shall agree (the
"CLOSING DATE"). At the Closing, the Company will deliver to Investor a
certificate evidencing 200,000 shares of Preferred Stock, which shall be
registered in Investor's name as stated on the signature page hereto, against
delivery to the Company of payment by wire transfer in immediately available
funds in an amount equal to the Required Payment. As additional consideration
for its commitment to engage in the transactions described herein, on or
before the Closing the Company shall pay to Investor by wire transfer a
structuring fee equal to One Million Dollars ($1,000,000.00), one half of
which shall have been paid on or before October 15, 1996 (if earlier than the
Closing Date).

         4.    REGISTER OF SECURITIES; RESTRICTIONS ON TRANSFER OF SECURITIES;
REMOVAL OF RESTRICTIONS ON TRANSFER OF SECURITIES.

               4.1   REGISTER OF SECURITIES. The Company or its duly appointed
agent shall maintain a separate register for the shares of Preferred Stock and
Class A and Class B Common Stock and for the Warrants, in which it shall
register the issue and sale of all such shares and the issuance of the
Warrants. All transfers of Preferred Stock, Class A or Class B Common Stock or
Warrants shall be recorded on the register maintained by the Company or its
agent, and the Company shall be entitled to regard the registered holder of
such Securities as the actual holder of the Securities so registered until the
Company or its agent


                                      -2-


<PAGE>   6



is required to record a transfer of such Securities on its register. Subject
to Section 4.2 hereof, the Company or its agent shall be required to record
any such transfer by Investor or another registered holder thereof when it
receives the Security to be transferred, duly and properly endorsed by
Investor or another registered holder thereof or by its attorney-in-fact duly
authorized in writing.

         4.2    RESTRICTIONS ON TRANSFER.

               (a)   Investor understands and agrees that the Securities it will
be acquiring have not been registered under the Securities Act of 1933, as
amended (together with the rules and regulations promulgated thereunder, the
"SECURITIES ACT"), or under applicable state securities laws and that
accordingly they will not be transferable except as permitted under various
exemptions contained in the Securities Act and any applicable state securities
laws, or upon satisfaction of the registration and prospectus delivery
requirements of the Securities Act and applicable state securities laws.
Investor acknowledges and agrees that it must bear the economic risk of its
investment in the Securities for an indefinite period of time (subject,
however, to the Company's obligation to redeem the Preferred Stock in
accordance with the Certificate and to the Company's obligation to effect the
registration of the Class A Common Stock issuable upon exercise of the
Warrants under the Securities Act in accordance with the terms thereof as set
forth in the Warrant Certificate) because they have not been registered under
the Securities Act or applicable state securities laws, and therefore cannot
be sold, unless they are subsequently registered or an exemption from
registration is available; provided, that, prior to the sale of Securities
pursuant to an exemption, the Company may request delivery (not at the
Company's expense) of an unqualified opinion (reasonably satisfactory in form
and substance to the Company and its counsel) of counsel for Investor expert
in federal and state securities laws (which may be Company counsel) to the
effect that an exemption from registration is available. Prior to transferring
Securities pursuant to an exemption from registration, Investor shall provide
the Company with two (2) Business Days' prior notice. Investor further
acknowledges and agrees that, in addition to securities law restrictions on
transfer, the Securities may be transferred only in compliance with the rules
and regulations of the FCC.

               (b)   Investor hereby represents and warrants to the Company that
(i) it is acquiring the Securities it has agreed to purchase for investment
purposes, for its own account, and not with the view to, or for resale in
connection with, any distribution thereof within the meaning of the Securities
Act, (ii) it is an "accredited investor" as that term is defined in Rule 501
under the Securities Act, and a "qualified institutional buyer" as defined in
Rule 144A under the Securities Act, (iii) it has the power and authority under
Applicable Law and its organizational documents, and has taken all necessary
corporate or similar action to authorize it, to enter into this Agreement and
to purchase the Securities, (iv) approval of the FCC for the purchase by
Investor of the Securities is not required as a result of Investor's status
and (v) it has reviewed, among other things, the Prospectus and the bank
information memorandum prepared by the Company for delivery to potential
lenders under the Credit Agreement.

               (c) Investor hereby agrees with the Company as follows:

                   (i) Subject to Section 4.3 hereof, the certificates
evidencing the Securities it has agreed to purchase, and each certificate
issued in transfer thereof, will bear the following legend:

            "The securities evidenced by this certificate have not been
            registered under the Securities Act of 1933, as amended, or under
            any applicable state securities laws. These securities may not be
            sold or transferred in the absence of such registration or an
            exemption therefrom under such Act and under any applicable state
            securities laws."

Certificates evidencing the Securities Investor has agreed to purchase, and
each certificate issued in transfer thereof, will also bear the following
legend:

            "The rights of holders of the securities evidenced by this
            certificate are subject to the terms and conditions set forth in
            that certain Preferred Stock and Common Stock Warrant Purchase
            Agreement between Sygnet Wireless, Inc. and Toronto Dominion
            Investments, Inc. dated October 9, 1996, a copy of which will be
            provided by Sygnet Wireless, Inc. at the request of the holder
            hereof."

                   (ii) The certificates representing such Securities, and
each certificate issued in transfer thereof, will also bear any legend
required under any applicable state securities law.

                   (iii) Absent an effective registration statement under the
Securities Act covering the disposition of the Securities, Investor will not
sell, transfer, assign, pledge, hypothecate or otherwise dispose of any of the
Securities except in compliance with the Securities Act and the registration
or qualification requirements of any applicable state securities laws or any
exemption therefrom.

                   (iv) The Company may make a notation on its records or give
instructions to any transfer agent of the Class A Common Stock or Preferred
Stock in order to implement the restrictions on transfer of the Securities set
forth in this subsection (c).

         4.3   REMOVAL OF SECURITIES ACT TRANSFER RESTRICTIONS. Any legend
endorsed on a certificate evidencing a Security pursuant to Section 4.2(c)(i)
hereof and the stop transfer instructions and record notations with respect to
such Security shall be removed and the Company shall issue a certificate
without such legend to the Holder of such Security (a) if such Security is
registered under the Securities Act, or (b) if such Security may be sold under
Rule 144(k) of the Commission under the Securities Act or (c) if the Holder
provides the Company with an opinion of counsel expert in federal and state
securities laws (which may be counsel for the Company) in form and substance
reasonably acceptable to the Company and its counsel to the effect that a sale
or transfer of such Security may be made without registration under the
Securities Act and applicable state



                                      -4-

securities laws.

         4.4        TRANSFEREE ACKNOWLEDGEMENT. In addition to such other 
conditions as are stated above, to effect a transfer of Securities pursuant
hereto, each transferee of Securities hereunder shall acknowledge and agree in
writing that its rights and obligations with respect to such Securities are
governed by the terms and conditions of this Agreement.

         5.   REPRESENTATIONS AND WARRANTIES BY THE COMPANY. In order to induce
Investor to enter into this Agreement and to purchase the Preferred Stock and
Warrants, the Company hereby represents and warrants to Investor as follows:

                     5.1       REORGANIZATION; ORGANIZATION; POWER; 
                               QUALIFICATION; CAPITAL STOCK.

                               (a) The Reorganization was fully consummated on
September 30, 1996. The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Ohio. The Company
has the corporate power and authority to own or lease and operate its
properties and to carry on its business as it is now being conducted or as it
is proposed to be conducted in the immediate future. The Company is duly
qualified, in good standing and authorized to do business in each jurisdiction
in which the character of its properties or the nature of its businesses
requires such qualification or authorization, except in such jurisdictions
where the failure to so qualify would not have a Materially Adverse Effect.
ANNEX 5.1 correctly sets forth and identifies the number of authorized shares
of each class and series of capital stock of the Company and the number of
issued and outstanding shares of each such class and series on the date
hereof, after giving effect to the transactions contemplated hereby. Except as
described on ANNEX 5.1 attached hereto, the Company does not have outstanding
any stock or securities convertible into or exchangeable for any shares of its
Class A or Class B Common Stock, nor are there any preemptive or similar
rights to subscribe for or to purchase, or any other rights to subscribe for
or to purchase, or any options for the purchase of, or any agreements
providing for the issuance (contingent or otherwise) of, or any calls,
commitments, or claims of any character relating to, any Class A or Class B
Common Stock or any stock or securities convertible into or exchangeable for
any Class A or Class B Common Stock. Except as set forth on ANNEX 5.1, the
Company is not subject to any obligation (contingent or otherwise) to
repurchase or otherwise acquire or retire any shares of its Common Stock or to
register any shares of its Common Stock, and (other than restrictions on
changes in control of the Company under the Credit Facilities and the
Certificate) there are no agreements restricting the transfer of any shares of
the Company's Common Stock.

                               (b) Other than the Preferred Stock to be issued 
to the Investor pursuant to this Agreement and except as set forth on ANNEX
5.1, the Company has no authorized classes of preferred stock and there are no
shares of preferred stock outstanding. The Preferred Stock has been duly
authorized and, when issued and paid for pursuant to the terms of this
Agreement, will be duly authorized, validly issued, fully paid and
nonassessable, will have the rights, preferences and privileges specified in
the



                                      -5-


<PAGE>   9



Certificate and will be free and clear of all Liens and restrictions, other
than Liens that might have been created by Investor and restrictions on
transfer imposed by Section 4.2 hereof or applicable securities laws; the
Warrants have been duly authorized and, when issued pursuant to the terms of
this Agreement, will be duly authorized and validly issued and free and clear
of all Liens and restrictions, other than Liens that might have been created
by Investor and restrictions imposed by Section 4.2 hereof or applicable
securities laws; and the number of shares of Common Stock issuable upon
exercise in full of the Warrants has been or will timely be duly authorized
and has been or will timely be reserved for issuance upon exercise of the
Warrants and such shares, when issued upon exercise and in accordance with the
terms of the Warrant Certificate, will be duly authorized, validly issued,
fully paid and nonassessable Common Stock and free and clear of all Liens and
restrictions, other than Liens that might have been created by Investor and
restrictions imposed by Section 4.2 hereof or applicable securities laws.

                     5.2  AUTHORIZATION.  The Company has the corporate power 
and has taken all necessary corporate action to authorize it to issue the
Preferred Stock and the Warrants and to execute, deliver and perform this
Agreement, the Certificate, and the Warrant Certificate in accordance with
their respective terms, and to consummate the transactions contemplated hereby
and thereby. This Agreement has been duly executed and delivered by the
Company and is, and each of the Warrant Certificate and the Certificate is, a
legal, valid and binding obligation of the Company enforceable in accordance
with its terms, subject, as to enforcement, to the following qualifications:
(i) certain legal and equitable remedies are discretionary and, in particular,
may not be available where damages are considered an adequate remedy at law,
(ii) enforcement may be limited by bankruptcy, insolvency, liquidation,
reorganization, reconstruction, fraudulent conveyance, fraudulent transfer and
other similar laws affecting enforcement of creditors' rights generally, and
(iii) enforcement may be limited by FCC rules and regulations (and
corresponding federal law).

                     5.3  SUBSIDIARIES.  The only Subsidiary of the Company is 
Sygnet Communications, Inc. Each such Subsidiary is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. Each such Subsidiary has the corporate
power and authority to own or lease and operate its properties and to carry on

stock of the Company.

            9.   FAILURE TO PURCHASE PREFERRED STOCK UPON EXERCISE OF PUT. If,
for any reason whatsoever, all outstanding shares of Preferred Stock are not

Four, Paragraph H, Section 2(b)(v) of the Certificate. In addition, at the
request of Holders of a majority of the shares of Preferred Stock
participating in the Put (the "Sale Request"), the Company shall use its best
efforts, and those Holders of Class B Common Stock of the Company executing
the Joinder hereto shall use their best efforts, to effect the sale of all of
the outstanding stock of the Company, the merger or consolidation of the
Company with another entity or the sale of all or substantially all of the
assets of the Company in such manner so as to provide sufficient funds to pay
the Redemption Price in full (including all dividends which have accrued and
remain unpaid from the date of exercise of the Put until the date the Price is
actually paid). Such sale of the Company shall be consummated within twelve
(12) months from the date of the Sale Request.

            10.  ENFORCEMENT.

                 10.1   REMEDIES.  Except as provided in this Section 10 and in 
Section 11.6 of the Warrant Certificate, (a) the increase in the dividend
Applicable Rate for the Preferred Stock as provided in Section 2(b)(v) of the
Certificate (provided that the dividend Applicable Rate, upon notice from
Holders of a Majority of the Preferred Stock, shall also be increased in such
manner upon the failure to secure Raymond Tittle, Jr.'s signature to the
Joinder within the period set forth in Section 6.4(d), for a material Default
of the covenants set forth in Sections 7.1 through 7.6 and 8 hereof or
repeated failure to deliver the documents and notices required by Sections 7.7
through 7.9 hereof after written notice of failure to deliver from Holders of
a Majority of the Preferred Stock or for failure to deliver Warrants in
accordance with Section 2(b) hereof) and (b) the remedies provided in Section
9 hereof for a failure to purchase Preferred Stock upon exercise of the Put
are the sole remedies available to Investor or any Holder of Securities for
any Default or any other breach of this Agreement and related documents;
provided, that, nothing herein shall preclude a Holder of Securities from
pursuing such remedies as are available at law or equity for fraud (including
securities fraud) in connection with such Holder's investment in Securities of
the Company. Upon the failure to consummate a sale within twelve (12) months
from the date of a Sale Request as specified in Section 9 hereof, the Holders
of Preferred Stock may proceed to protect and enforce their rights by suit in
equity either through an action for the specific performance of Section 9 of
this Agreement or an action for an injunction against the breach of such
Section or in aid of the exercise of any power granted therein, or to enforce
any other equitable right of such Holders as a result of the breach of Section
9, or to take any one or more of such actions. In connection with such an
action the Holders may bring a claim against the Company for monetary damages
for a breach of the standard set forth in Section 9; provided, that, no action
other than an action for specific performance may be instituted against the
Holders of Class B Common Stock referred to in Section 9. In the event a
Holder brings an action pursuant hereto, the prevailing party in such dispute
shall be entitled to recover from the losing party all fees,



                                     -15-

expenses of attorneys and accountants, which shall include, without
limitation, all fees, costs and expenses of appeals.

                  10.2    CUMULATIVE REMEDIES.  None of the rights, powers or 
remedies conferred by this Agreement, the Certificate or the Warrant

Security created by the Certificate or by the Ohio General Corporation Law

Holder at a later time to enforce the same. No waiver by any party of the

deemed to be, or construed as, a further or continuing waiver of any such
