approximately 0.1% of the outstanding shares of Common Stock. Through his
ownership of stock of DNIC, Mr. De Nicolo also has an indirect beneficial

Common Stock held by the Foundation. Mr. De Nicolo disclaims beneficial
ownership with respect to all but 16,980 shares of Common Stock.

ITEM 5.           OWNERSHIP OF FIVE PERCENT OR LESS OF A CLASS

                  If this statement is being filed to report the fact that as of

more than five percent of the class of securities, check the following [X].

                  As of this date, the following reporting persons have ceased
to be the beneficial owner of more than five percent of the class of securities:

                  Columbia Capital Corporation
                  Columbia Cellular Investors
                  Mark J. Kington
                  David P. Mixer
                  James B. Murray, Jr.

ITEM 8.           IDENTIFICATION AND CLASSIFICATION OF MEMBERS OF THE GROUP.

                  Columbia Capital, DNIC, Motorola, and Telular Canada are
parties to an Amended and Restated Shareholders' Agreement dated November 2,
1993, as amended by Amendment No. 1 dated as of January 24, 1994 and as further
amended by Amendment No. 2 dated as of June 29, 1995 (the "Shareholders'
Agreement") that, until recently, imposed certain restrictions on the voting and
transfer of Common Stock held by those persons. Pursuant to the terms of the
Shareholders' Agreement, many of these restrictions have since expired. 

                  Because these restrictions are no longer applicable, Columbia
Capital, DNIC, Motorola, and Telular Canada, as parties to the Shareholders'
Agreement, no longer constitute a group. The remaining material provisions
permit Motorola to designate certain directors and provide Motorola     with a
limited right of first refusal.  Motorola has the right to nominate for
election a number of directors proportionate to its respective holdings of
outstanding shares, rounded up to the nearest whole number (provided, that, so
long as it holds at least 10% of the outstanding shares of Common Stock it may
nominate at least one director, and that as long as it holds at least 20% of
the outstanding shares of Common Stock it may nominate at least two directors).
The parties to the Shareholders' Agreement have agreed to vote in favor of each
such nominee.  If the Company or the reporting persons receive an unsolicited
offer to acquire a majority of the Common Stock or all or substantially all of
the Company's assets, they must notify Motorola. If the Company or the
reporting persons intend to consider the offer, Motorola will have the right to
submit a bid as well. The Company and such reporting persons may not approve a
transaction with a third party that is at a valuation lower than that offered
by Motorola. The rights of Motorola will terminate upon any sale by Motorola of
shares of Common Stock after which Motorola owns less than 20% of the
outstanding shares of Common Stock on a fully diluted basis.

                  Robert Blow, Mark Kington, David Mixer, James Murray and 
Mark Warner, in their capacities as directors of Columbia Capital, may be 
deemed to share voting and investment power with respect to the shares held
by Columbia Capital. Similarly, William De Nicolo, in his capacity as an
officer, director, and principal shareholder of DNIC and as an officer and
director of the Foundation, may be deemed to share voting and investment power
with respect to all shares of Common Stock held by DNIC and the Foundation.

ITEM 9.           NOTICE OF DISSOLUTION OF GROUP.

                  As discussed in the response to Item 8 hereof, Columbia
Capital, DNIC, Motorola, and Telular Canada, as parties to the Shareholders'
Agreement, no longer constitute a group for purposes of disclosure under
Schedule 13G. Any further filings

                               Page 17 of 23 pages
<PAGE>   18
with respect to transactions in the Common Stock will be filed, if required, by
these parties in their individual capacities.

                  Robert Blow, Mark Kington, David Mixer, James Murray and Mark
Warner, in their capacities as directors of Columbia Capital may be deemed to
share voting and investment power with respect to the shares held by Columbia
Capital. Any further filings with respect to transactions in the Common Stock
will be filed, if required, by Messrs. Blow, Kington, Mixer, Murray, Warner and
Columbia Capital separately.

                  Similarly, William De Nicolo, in his capacity as an officer,
director, and principal shareholder of DNIC, may be deemed to share voting and
investment power with respect to all shares of Common Stock held by DNIC. Any
further filings with respect to transactions in the Common Stock will be filed,
if required, by Mr. De Nicolo and DNIC separately.

ITEM 10.          CERTIFICATION.

                  By signing below, I certify that, to the best of my knowledge
and belief, the securities referred to above were acquired in the ordinary
course of business and were not acquired for the purpose of and do not have the
effect of changing or influencing the control of the issuer of such securities
and were not acquired in connection with or as a participant in any transaction
having such purposes or effect.

ITEM 8.           IDENTIFICATION AND CLASSIFICATION OF MEMBERS OF THE GROUP.

                  The reporting persons were all parties to an Amended and
Restated Shareholders' Agreement dated November 2, 1993, as amended January 24,
1994 (the "Shareholders' Agreement"), that contains certain provisions as to the
voting and transfer of Common Stock held by those persons. As of June 29, 1995,
the Shareholders' Agreement was amended by Amendment No. 2 thereto to release
certain shareholders from the terms and conditions of the Agreement. Columbia
Investors, Columbia Capital, DNIC, Motorola, and Telular Canada remain parties
to the Shareholders' Agreement, as amended.

                  Pursuant to the Shareholders' Agreement, each of Telular
Canada and Motorola has the right to nominate for election a number of directors
proportionate to its respective holdings of outstanding shares, rounded to the
nearest whole number in the case of Telular Canada and rounded up to the nearest
whole number in the case of Motorola (provided, in the case of Telular Canada,
that so long as it holds at least 10% of the outstanding shares of Common Stock
it may nominate at least one director and, in the case of Motorola, that so long
as it holds at least 10% of the outstanding shares of Common Stock it may
nominate at least one director, and that as long as it holds at least 20% of the
outstanding shares of Common Stock it may nominate at least two directors), and
the reporting persons have agreed to vote in favor of each such nominee.

                  Until such time as all Common Stock owned by Telular Canada is
freely available to be traded, subject to United States securities laws, the
shares held by the reporting parties are subject either to a right of first
refusal prior to sale or, in the event of a sale of more than 10% of the shares
held by a reporting person, a right to have their shares sold together with
those of the selling reporting person.

                  If at any time the Company or the reporting persons receive an
unsolicited offer to acquire a majority of the Common Stock or all or
substantially all of the Company's assets, they must notify Motorola. If the
Company or the reporting persons intend to consider the offer, Motorola will
have the right to submit a bid as well. The Company and such reporting persons
may not approve a transaction with a third party that is at a valuation lower
than that offered by Motorola. The rights of Motorola will terminate upon any
sale by Motorola of shares of Common Stock after which Motorola owns less than
20% of the outstanding shares of Common Stock on a fully diluted basis.

                  A copy of Amendment No. 2 to the Shareholders' Agreement is
attached.

ITEM 9.           NOTICE OF DISSOLUTION OF GROUP.

                  As discussed in the response to Item 8 hereof, the
Shareholders' Agreement was amended as of June 29, 1995 to release certain
shareholders from the

                             Page 30 of 36 pages

<PAGE>   58

Shareholders' Agreement. Joel Bellows, Marvin Benn, William L. De Nicolo, George
Hamman, Lars Nilsson, Robert Blow, Mark Kington, David Mixer, James Murray, Mark
Warner, Prudential, Menestrel, Richard T. Gerstner, Luis Romero Font, Luis
Romero Graziani, and Luis R. Ortiz Perez are no longer parties to the
Shareholders' Agreement and, therefore, are no longer members of the group that
was deemed constituted by inclusion in the Shareholders' Agreement. Any further
filings with respect to transactions in the Common Stock will be filed, if
required, by these parties in their individual capacities.

                  Nevertheless, Robert Blow, Mark Kington, David Mixer, James
Murray and Mark Warner, through their common ownership of Columbia Investors,
and Columbia Capital (the "Columbia Entities"), may be deemed to share
beneficial ownership with respect to the shares held by the Columbia Entities.
Any further filings with respect to transactions in the Common Stock will be
filed, if required, by Messrs. Blow, Kington, Mixer, Murray, Warner and the
Columbia Entities separately.

ITEM 10.          CERTIFICATION.

                  By signing below, I certify that, to the best of my knowledge
and belief, the securities referred to above were acquired in the ordinary
course of business and were not acquired for the purpose of and do not have the

having such purposes or effect.

ITEM 7.  IDENTIFICATION AND CLASSIFICATION OF THE SUBSIDIARY WHICH ACQUIRED THE
         SECURITY BEING REPORTED ON BY THE PARENT HOLDING COMPANY.

         Not applicable.

ITEM 8.  IDENTIFICATION AND CLASSIFICATION OF MEMBERS OF THE GROUP.

                  The reporting persons were all parties to an Amended and
Restated Shareholders' Agreement dated November 2, 1993, as amended January 24,
1994 (the "Shareholders' Agreement"), that contains certain provisions as to the
voting and transfer of Common Stock held by those persons. Pursuant to the
Shareholders' Agreement, each of Telular Canada and Motorola has the right to
nominate for election a number of directors proportionate to its respective
holdings of outstanding shares, rounded to the nearest whole number in the case
of Telular Canada and rounded up to the nearest whole number in the case of
Motorola (provided, in the case of Telular Canada, that so long as it holds at
least 10% of the outstanding shares of Common Stock it may nominate at least one
director and, in the case of Motorola, that so long as it holds at least 10% of
the outstanding shares of Common Stock it may nominate at least one director,
and that as long as it holds at least 20% of the outstanding shares of Common
Stock it may nominate at least two directors), and the reporting persons have
agreed to vote in favor of each such nominee.

                  Until such time as all Common Stock owned by Telular Canada is
freely available to be traded, subject to United States securities laws, the
shares held by the reporting parties are subject either to a right of first
refusal prior to sale or, in the event of a sale of more than 10% of the shares
held by a reporting person, a right to have their shares sold together with
those of the selling reporting person.

                  If at any time the Company or the reporting persons receive an
unsolicited offer to acquire a majority of the Common Stock or all or
substantially all of the Company's assets, they must notify Motorola. If the
Company or the reporting persons intend to consider the offer, Motorola will
have the right to submit a bid as well. The Company and such reporting persons
may not approve a transaction with a third party that is at a valuation lower
than that offered by Motorola. The rights of Motorola will terminate upon any
sale by Motorola of shares of Common Stock after which Motorola owns less than
20% of the outstanding shares of Common Stock on a fully diluted basis.

                  A copy of the Shareholders' Agreement is attached.
