through June 30, 1998.  This unaudited interim information should be read in
conjunction with the audited consolidated financial statements of the Company
and the notes thereto for the year ended December 31, 1997.  Operating results
for the period May 13, 1998 (inception) through June 30, 1998 are not
necessarily indicative of the results that may be expected for the period
May 13, 1998 (inception) through December 31, 1998.


2.   MANDATORILY REDEEMABLE PREFERRED SECURITIES

     During May 1998, Funding completed the sale of Preferred Securities for
gross proceeds of $110,000,000.  Net proceeds from the offering, after offering
costs, were approximately $105,940,000.  The recorded amount of the Preferred
Securities will fully accrete to the face value of $110,000,000 on June 1, 2010.
The restricted cash at June 30, 1998 of approximately $21,539,000 includes the
proceeds of the offering which are designated for the payment of cash dividends
on the Preferred Securities through June 1, 2001.  Funding invested the
restricted cash in U.S. Treasury strips ("Treasury Strips") which were placed in
escrow upon the closing of the offering of the Preferred Securities.  The
Treasury Strips have been pledged to The Bank of New York as escrow agent (the
"Escrow Agent") pursuant to an escrow agreement for the benefit of the holders
of the Preferred Securities.  The Escrow Agent is required under the Escrow
Agreement to release from escrow amounts sufficient to pay quarterly dividends
on the Preferred Securities through September 1, 2001.

     The Preferred Securities consist of 4,400,000 exchangeable preferred
securities of Funding that bear a cumulative dividend at the rate of 7% per
annum.  The dividend is paid quarterly in arrears each March 1, June 1,
September 1 and December 1, commencing September 1, 1998.  The dividend is
payable in cash through June 1, 2001 and thereafter, by cash or shares of
CellNet common stock, at the option of Funding.  The Preferred Securities are
exchangeable at any time prior to June 1, 2010, at the option of the holders,
into CellNet common stock, at a rate of 1.8328 shares of common stock per
Preferred Security, or $13.64 per share, subject to adjustment.  On or prior to
June 1, 2001, the Preferred Securities must be automatically exchanged for
common stock of the Company at an exchange price of $13.64 per share in the
event the Current Market Value (which is a formula as defined in the Written
Action of the Manager of  Funding, the "Written Action") of the Company's common
stock equals or exceeds the following percentage of the exchange price, for at
least 20 days of any 30-day trading period during the 12 month period ending
prior to June 1 of the indicated year: 170% prior to June 1, 1999; 160% from
June 1, 1999 through June 1, 2000; and 150% from June 2, 2000 up to and prior to
June 1, 2001.  The Preferred Securities are subject to mandatory redemption on
June 1, 2010 at a redemption price of 100% of the liquidation preference of the
Preferred Securities, plus accrued and unpaid dividends, if any.  Funding may
redeem, at its option, the Preferred Securities, in whole or in part, at any
time on or after June 1, 2001 at certain redemption prices equal to


                                         -6-
<PAGE>

a percentage of the liquidation preference (set forth in the Written Action)
which declines each year until maturity of the Preferred Securities, together
with accrued and unpaid dividends, if any.

     Pursuant to and to the extent set forth in the guarantee of the Preferred
Securities (the "Guarantee") by  the Company for the benefit of the holders of
Preferred Securities, CellNet has agreed to pay in full to the holders of the
Preferred Securities (except to the extent paid by Funding), as and when due,
regardless of any defense, right of set off or counterclaim which Funding may
have or assert, the following payments (the "Guarantee Payments"), without
duplication:  (i) any accrued and unpaid distributions that are required to be
paid on the Preferred Securities, to the extent Funding has sufficient funds
legally available thereof, (ii) the redemption price, with respect to any
Preferred Securities called for redemption by Funding, to the extent Funding has
sufficient funds legally available therefor and (iii) upon a voluntary or
involuntary dissolution, winding-up or termination of Funding, the lesser of (a)
the aggregate of the liquidation preference and all accrued and unpaid dividends
on the Preferred Securities to the date of payment to the extent Funding has
sufficient funds legally available therefor and (b) the amount of assets of
Funding remaining for distribution to holders of Preferred Securities upon the
liquidation of Funding.  The Guarantee may also be subject to contractual
restrictions under agreements governing future indebtedness of the Company.

     On May 19, 1998, after the investment in Treasury Strips, Funding applied
the remaining net proceeds from the offering of the Preferred Securities
together with other capital contributed by CellNet to purchase $93,500,000 of
CellNet Data Systems, Inc. Preferred Stock (the "CellNet Preferred Stock") which
pays dividends each March 1, June 1, September 1 and December 1 in additional
shares of CellNet Preferred Stock through June 1, 2001.  Subsequent to June 1,
2001, dividends are payable in cash or shares of common stock, at the option of
CellNet.  The CellNet Preferred Stock is exchangeable, at the option of Funding,
at any time prior to June 1, 2010 into shares of common stock at an exchange
rate based on the exchange rate of the Preferred Securities.  The CellNet
Preferred Stock is subject to mandatory redemption on June 1, 2010.

FUNDING'S ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THE RESULTS DISCUSSED IN THE
FORWARD-LOOKING STATEMENTS AND THE VARIATIONS MAY BE MATERIAL AS A RESULT OF
CERTAIN FACTORS SET FORTH IN "RISK FACTORS" AND ELSEWHERE IN THIS REPORT.  AS A
WHOLLY-OWNED SUBSIDIARY OF CELLNET DATA SYSTEMS, INC. WITH NO INDEPENDENT
OPERATIONS, FUNDING'S SUCCESS IS ENTIRELY DEPENDENT ON THE SUCCESS OF IT PARENT,
AND ACCORDINGLY, REFERENCE MUST ALSO BE MADE TO THE RISK FACTORS AND OTHER
CAUTIONARY STATEMENTS SET FORTH IN CELLNET DATA SYSTEM'S ANNUAL REPORT ON FORM
10-K, QUARTERLY REPORTS ON FORM 10-Q AND OTHER FILINGS WITH THE SECURITIES AND
EXCHANGE COMMISSION.

OVERVIEW

     CellNet Funding, L.L.C. ("Funding") is  a special purpose limited liability
company formed under the laws of the State of Delaware on May 13, 1998 as a
wholly-owned subsidiary of CellNet Data Systems, Inc. ("CellNet" or the
"Company").  Funding has no independent operations and exists for the exclusive
purposes of issuing exchangeable preferred securities, investing the proceeds of
the sale thereof and engaging in other activities necessary or incidental
thereto.  During May 1998, Funding completed the sale of 7% Exchangeable
Preferred Securities Mandatorily Redeemable 2010 (the "Preferred Securities")
for gross proceeds of $110,000,000.  Net proceeds from the offering, after
offering costs, were approximately $105,940,000.

     The Preferred Securities consist of 4,400,000 exchangeable preferred
securities of Funding that bear a cumulative dividend at the rate of 7% per
annum.  The dividend is paid quarterly in arrears each March 1, June 1,
September 1 and December 1, commencing September 1, 1998.  The dividend is
payable in cash through June 1, 2001 and thereafter, by cash or shares of
CellNet common stock, at the option of Funding.  The Preferred Securities are
exchangeable at any time prior to June 1, 2010, at the option of the holders,
into CellNet common stock, at a rate of 1.8328 shares of common stock per
Preferred Security, or $13.64 per share, subject to adjustment.  On or prior to
June 1, 2001, the Preferred Securities must be automatically exchanged for
common stock of the Company at an exchange price of $13.64 per share in the
event the Current Market Value (which is a formula as defined in the Written
Action of the Manager of Funding, the "Written Action") of the Company's common
stock equals or exceeds the following percentage of the exchange price, for at
least 20 days of any 30-day trading period during the 12 month period ending
prior to June 1 of the indicated year: 170% prior to June 1, 1999; 160% from
June 1, 1999 through June 1, 2000; and 150% from June 2, 2000 up to and prior to
June 1, 2001.  The Preferred Securities are subject to mandatory redemption on
June 1, 2010 at a redemption price of 100% of the liquidation preference of the
Preferred Securities, plus accrued and unpaid dividends, if any.  Funding may
redeem, at its option, the Preferred Securities, in whole or in part, at any
time on or after June 1, 2001 at certain redemption prices equal to a percentage
of the liquidation preference (set forth in the Written Action) which declines
each year until maturity of the Preferred Securities, together with accrued and
unpaid dividends, if any.

     Pursuant to and to the extent set forth in the guarantee of the Preferred
Securities (the "Guarantee") by  the Company for the benefit of the holders of
Preferred Securities, CellNet has agreed to pay in full to the holders of the
Preferred Securities (except to the extent paid by Funding), as and when due,
regardless of any defense, right of set off or counterclaim which Funding may
have or assert, the following payments, without duplication:  (i) any accrued
and unpaid distributions that are required to be paid on the Preferred
Securities, to the extent Funding has sufficient funds legally available
thereof, (ii) the redemption price, with respect to any Preferred Securities
called for redemption by Funding, to the extent Funding has sufficient funds
legally available therefor and (iii) upon a voluntary or involuntary
dissolution, winding-up or termination of Funding, the lesser of (a) the
aggregate of the liquidation preference and all accrued and unpaid dividends on
the Preferred Securities to the date of payment to the extent Funding has
sufficient funds legally available therefor and (b) the amount of assets of
Funding remaining


                                         -8-
<PAGE>

for distribution to holders of Preferred Securities upon the liquidation of
Funding.  The Guarantee may also be subject to contractual restrictions under
agreements governing future indebtedness of the Company.

     The Preferred Securities are subject to mandatory redemption on June 1,
2010 at a redemption price of 100% of the liquidation preference of the
Preferred Securities, plus accrued and unpaid dividends, if any.  Funding may
redeem, at its option, the Preferred Securities, in whole or in part, at any
time on or after June 1, 2001 at certain redemption prices equal to a percentage
of the liquidation preference (set forth in the Written Action) which declines
each year until maturity of the Preferred Securities, together with accrued and
unpaid dividends, if any.

RESULTS OF OPERATIONS

     Funding is a wholly-owned finance subsidiary of CellNet, has no independent
operations, and exists for the purposes of issuing Preferred Securities and
investing the proceeds from the sale thereof  and engaging in other activities
necessary or incidental thereto. The restricted cash at June 30, 1998 of
approximately $21,539,000 includes a portion of the proceeds of the offering of
Preferred Securities which are designated for the payment of cash dividends
through June 1, 2001.  Funding invested the restricted cash in U.S. Treasury
strips ("Treasury Strips") which were placed in escrow upon the closing of the
offering of the Preferred Securities.  During the period of inception of Funding
through June 30, 1998, Funding earned $136,000 of interest on the amounts
invested in Treasury Strips and incurred $938,000 of dividend expense and
accretion on the Preferred Securities, for an aggregate net loss of $802,000.
Funding expects that dividend expenses will be approximately $1.9 million per
quarter, absent conversions or redemptions of the Preferred Securities.

LIQUIDITY AND CAPITAL RESOURCES

     During May 1998, Funding completed the sale of  Preferred Securities for
gross proceeds of $110,000,000.  Net proceeds from the offering, after offering
costs, were approximately $105,940,000.  The amount recorded as equity for the
Preferred Securities will fully accrete to the face value of $110,000,000 on
June 1, 2010.

     The restricted cash at June 30, 1998 of approximately $21,539,000 includes
the proceeds of the offering which are designated for the payment of cash
dividends on the Preferred Securities through June 1, 2001.  Funding invested
the restricted cash in Treasury Strips which were placed in escrow upon the
closing of the offering of the Preferred Securities. On May 19, 1998, after the
investment in Treasury Strips, Funding applied the remaining net proceeds from
the offering of the Preferred Securities together with other capital contributed
by CellNet to purchase $93,500,000 of CellNet Preferred Stock (the "CellNet
Preferred Stock") which pays dividends each March 1, June 1, September 1 and
December 1 in additional shares of CellNet Preferred Stock through June 1, 2001.
Subsequent to June 1, 2001, dividends are payable in cash or shares of common
stock, at the option of CellNet.  The CellNet Preferred Stock is exchangeable,
at the option of Funding, at any time prior to June 1, 2010 into shares of
common stock at an exchange rate based on the exchange rate of the Preferred
Securities.  The CellNet Preferred Stock is subject to mandatory redemption on
June 1, 2010.

     The Preferred Securities bear a cumulative dividend at the rate of 7% per
annum which must be paid quarterly in arrears each March 1, June 1, September 1
and December 1, commencing September 1, 1998.  The dividend is payable in cash
through June 1, 2001 and thereafter, by cash or shares of CellNet common stock,
at the option of Funding.  The Treasury Strips have been pledged to The Bank of
New York as escrow agent (the "Escrow Agent") pursuant to an escrow agreement
for the benefit of the holders of the Preferred Securities.  The Escrow Agent is
required under the Escrow Agreement to release from escrow amounts sufficient to
pay quarterly dividends on the Preferred Securities through September 1, 2001.

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

     FUNDING IS A WHOLLY-OWNED FINANCE SUBSIDIARY OF CELLNET, HAS NO INDEPENDENT
OPERATIONS AND EXISTS FOR THE PURPOSES OF ISSUING PREFERRED SECURITIES AND
INVESTING THE PROCEEDS FROM THE SALE THEREOF AND ENGAGING IN OTHER ACTIVITIES
NECESSARY OR INCIDENTAL THERETO.  THE SUCCESS OF FUNDING IS COMPLETELY DEPENDENT
UPON THE SUCCESS OF CELLNET, AND ACCORDINGLY, REFERENCE MUST BE MADE TO THE RISK
FACTORS AND OTHER CAUTIONARY STATEMENTS SET FORTH IN CELLNET'S ANNUAL REPORT ON
FORM 10-K, QUARTERLY REPORTS ON FORM 10-Q AND OTHER FILINGS WITH THE SECURITIES
AND EXCHANGE COMMISSION.

NO OPERATIONS OF FUNDING

     Funding, the issuer of the Preferred Securities, is a special purpose
subsidiary of CellNet which is a newly formed Delaware limited liability company
with no operations or assets other than the CellNet Preferred Stock and Treasury
Strips which were purchased with the proceeds of the offering of the Preferred
Securities.  Funding will have no other funds to pay cash dividends.  In order
to pay subsequent dividends, Funding will be dependent on CellNet (i) to
distribute cash dividends in respect of the CellNet Preferred Stock (which
distribution is restricted by the terms of the indenture governing the 1997
Notes) (the "Indenture")), (ii) provide to Funding funds or (iii) issue to
Funding common stock (which is required by the terms of the CellNet Preferred
Stock).  Funding's assets will consist almost entirely of its interest in the
CellNet Preferred Stock and the Treasury Strips.

NO PRACTICAL BENEFIT TO HOLDERS FROM THE GUARANTEE

     CellNet will guarantee the payment in full to the holders of the Preferred
Securities of (i) accrued and unpaid dividends on the Preferred Securities, if
and only to the extent Funding has funds sufficient and legally available
therefor to make such payment, (ii) the redemption price with respect to the
Preferred Securities redeemed, if and only to the extent Funding has funds
sufficient and legally available therefor to make such payment and (iii) upon a
voluntary termination or involuntary dissolution, winding-up or termination of
Funding (other than in connection with a redemption of all of the Preferred
Securities), the lesser of (a) the aggregate of the liquidation preference and
all accrued and unpaid dividends on the Preferred Securities to the date of
payment, to the extent Funding has funds sufficient and legally available
therefor to make such payment, and (b) the amount of assets of Funding remaining
available for distribution to holders of the Preferred Securities upon
liquidation of Funding.  The Guarantee may also be subject to contractual
restrictions under agreements governing future indebtedness of CellNet.

     Because the obligations supported by the Guarantee are limited by the
amount of the funds in Funding, if CellNet were to default on its obligation to
pay amounts payable on the CellNet Preferred Stock, Funding would lack available
funds for the payment of dividends or amounts payable on redemption of the
Preferred Securities or otherwise, and, in such event, holders of the Preferred
Securities would not be able to rely upon the Guarantee for payment of such
amounts.  In addition, upon the initiation of any proceedings by or against
Funding under bankruptcy, insolvency or similar laws, or upon the occurrence of
certain other events, funds held by Funding may not be legally available for
distribution to the holders of the Preferred Securities and the holders would
then not be able to rely on the Guarantee for payment of such amounts.

     Because the obligations supported by the Guarantee are limited to the
amount of the funds held by Funding that are legally available to make the
payments described above and because the Guarantee is subordinated to CellNet's
existing and future obligations not expressly subordinated to the Guarantee, the
Guarantee is of no practical benefit to holders of the Preferred Securities.


                                         -10-
<PAGE>

RANKING OF CELLNET PREFERRED STOCK; PRIOR PAYMENT OBLIGATIONS OF CELLNET;
UNCERTAINTY OF REDEMPTION

     The CellNet Preferred Stock will be subordinated to all existing and future
indebtedness and other liabilities of CellNet, and will, with respect to
dividend distributions and distributions upon the liquidation, winding-up or
dissolution of CellNet, rank senior to all common stock and senior to or PARI
PASSU with all other capital stock of CellNet.  There are no terms in the
CellNet Preferred Stock, the Preferred Securities or the Guarantee that limit
CellNet's ability to incur additional indebtedness or issue PARI PASSU preferred
stock.  As of June 30, 1998, the Company had approximately $291.7 million of
indebtedness outstanding and no preferred stock outstanding other than the
CellNet Preferred Stock issued to Funding.  CellNet has authorized the issuance
of up to 15 million shares of preferred stock.  The Indenture permits CellNet to
incur substantial additional indebtedness and issue additional preferred stock.
Any new indebtedness incurred by CellNet, any securities issued to refinance
existing indebtedness and any future issuances of new series of CellNet
preferred stock may prohibit or restrict the redemption of the CellNet Preferred
Stock for cash, thus effectively prohibiting or restricting Funding's ability to
redeem the Preferred Securities for cash.

RISK FACTORS RELATED TO CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     PARTNERSHIP STATUS

     Funding's ability to pay dividends on Preferred Securities depends, in
part, on the classification and treatment of Funding as a partnership for
federal income tax purposes.  Assuming the accuracy of certain factual matters
as to which Funding has made representations, counsel is of the opinion that,
under current law, Funding will be classified and treated as a partnership for
federal income tax purposes.  No ruling from the Internal Revenue Service (the
"IRS") as to such classification or treatment has been or is expected to be
requested.  Instead, Funding intends to rely on such opinion of counsel (which
is not binding on the IRS).

     If Funding were classified or treated as an association taxable as a
corporation for federal income tax purposes, Funding would pay tax on its income
at corporate rates (currently a maximum 35% federal rate), distributions would
generally be taxed again to the holders of Preferred Securities as corporate
distributions, and no income, gains, losses or deductions would flow through to
the holders of Preferred Securities.  Because a tax would be imposed upon
Funding as an entity, the cash available for distribution to the holders of
Preferred Securities would be substantially reduced.  Classification or
treatment of Funding as an association taxable as a corporation or otherwise as
a taxable entity would result in a material reduction in the anticipated cash
flow and after-tax return of the holders of Preferred Securities and thus would
likely result in a substantial reduction in the value of Preferred Securities.

     FUNDING ALLOCATIONS

     It is possible that a holder of Preferred Securities may receive
allocations of taxable income without matching cash distributions.  Furthermore,
a holder who disposes of Preferred Securities between record dates for dividends
may be required pursuant to Funding's method of allocation to include its pro
rata share of Funding's income (and deductions) through the end of the
applicable fiscal period in which such disposition occurs in the holder's
calculation of taxable income (and to add such amount to (or subtract such
amount from) the adjusted tax basis in the holder's Preferred Securities)
without receiving the dividend for the quarter in which such disposition occurs.
Furthermore, certain allocation methods used by Funding may be challenged by the
IRS, which may result in greater tax liability to holders of Preferred
Securities during their period of ownership or upon disposition.


                                         -11-
<PAGE>

     DISPOSITION OF PREFERRED SECURITIES

     A holder that sells Preferred Securities will recognize gain or loss equal
to the difference between the amount realized and its adjusted tax basis in such
Preferred Securities.  Thus, prior Funding distributions in excess of cumulative
net taxable income in respect of Preferred Securities which decreased a holder's
tax basis in such Preferred Securities will, in effect, become taxable income or
gain if the Preferred Securities are sold at a price greater than the holder's
tax basis in such Preferred Securities, even if the price is less than such
holder's original cost.  To the extent the selling price is less than the
holder's adjusted tax basis, a holder will recognize a capital loss.  Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.

LIMITED VOTING RIGHTS

     Generally, holders of the Preferred Securities do not have any voting
rights.  However, the vote of a majority of the Preferred Securities is required
to approve any amendment to the Operating Agreement governing Funding or any
proposed action by Funding that would (i) have a material adverse effect on the
powers, preferences or special rights of the holders of the Preferred Securities
or (ii) cause the dissolution, winding-up or termination of Funding.  The
approval of the holders of a majority of the CellNet Preferred Stock is required
to approve any change to CellNet's charter or any proposed action by CellNet
that would (i) have a material adverse effect on the powers, preferences or
special rights  of the holder of the CellNet Preferred Stock or (ii) cause the
dissolution, winding-up or termination of Funding.  Funding is expected to be
the sole holder of the CellNet Preferred Stock.  Funding has agreed not to grant
such approval without the consent of the holders of a majority of the Preferred
Securities then outstanding.

ANTI-TAKEOVER PROVISIONS

     The Board of Directors of CellNet, without further stockholder approval,
can issue preferred shares with dividend, liquidation, conversion, voting,
exchange or other rights which could adversely affect the voting power or other
rights of the holders of the common stock.  In the event of issuance, the
preferred shares could be utilized, under certain circumstances, as a method of
discouraging, delaying or preventing a change of control of CellNet.  In
addition, the Company is, and will continue to be, subject to the anti-takeover
provisions of the Delaware General Corporation Law, which could have the effect
of delaying or preventing a change of control of the Company.  Furthermore, upon
a change of control, the holders of substantially all of the Company's
outstanding indebtedness are entitled, at their option, to be repaid in cash and
the holders of CellNet's preferred stock may, at their option, require CellNet
to redeem their shares for cash.  Such provisions may have the effect of
delaying or preventing changes in control or management of the Company.  All of
these factors could materially adversely affect the price of the Preferred
Securities.
