              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

(1)    BUSINESS AND ORGANIZATION

       CDSI Holdings Inc. (the "Company" or "CDSI") was incorporated in Delaware
       on December 29, 1993. On January 12, 1999, the Company's stockholders
       voted to change the corporate name of the Company from PC411, Inc. to
       CDSI Holdings Inc. Prior to May 8, 1998, the Company's principal business
       was an on-line electronic delivery information service that transmits
       name, address, telephone number and other related information digitally
       to users of personal computers (the "PC411 Service"). On May 8, 1998, the
       Company acquired Controlled Distribution Systems, Inc. ("CDS", formerly
       known as Coinexx Corporation), a company engaged in the marketing and
       leasing of an inventory control system (the "Coinexx Star 10") for
       tobacco products. In February 2000, CDSI announced CDS will no longer
       actively engage in the business of marketing and leasing an inventory
       control system for tobacco products.

       CDSI intends to explore investments in other Internet-related businesses
       as well as other business opportunities. As CDSI has only limited cash
       resources, CDSI's ability to complete any acquisition or investment
       opportunities it may identify will depend on its ability to raise
       additional financing, as to which there can be no assurance.

(2)    PRINCIPLES OF REPORTING

       The financial statements of the Company as of June 30, 2001 presented
       herein have been prepared by the Company and are unaudited. In the
       opinion of management, all adjustments, consisting only of normal
       recurring adjustments, necessary to present fairly the financial position
       as of June 30, 2001 and the results of operations and cash flows for all
       periods presented have been made. Results for the interim periods are not
       necessarily indicative of the results for the entire year.

       These financial statements should be read in conjunction with the audited
       financial statements and notes thereto for the year ended December 31,
       2000 included in the Company's Form 10-KSB filed with the Securities and
       Exchange Commission (Commission File No. 0001-22563).

       USE OF ESTIMATES

       The preparation of the financial statements in conformity with generally
       accepted accounting principles requires management to make estimates and
       assumptions that affect the reported amounts of assets and liabilities
       and disclosure of contingent assets and liabilities at the date of the
       financial statements and the reported amounts of revenue and expenses
       during the reporting period. Actual results could differ from those
       estimates.

                                   (UNAUDITED)

(3)    CDS ACQUISITION

       On May 8, 1998, the Company acquired CDS, a company engaged in the
       marketing and leasing of an inventory control system for tobacco
       products. Under the terms of the acquisition, the CDS stockholders
       received 147,500 shares of the Company's Common Stock at closing. In
       addition, the Company agreed to issue an additional 147,500 shares to CDS
       stockholders on each of the second, third and fourth anniversaries of the
       closing provided that, on each such delivery date, CDS was actively
       engaged in the business it is now engaged. As the Company is no longer
       engaged in the marketing and leasing of the Coinexx Star 10, the
       contingent shares will not be issued.

       CDS did not have any significant tangible assets at the time of
       acquisition. The fair value of the shares issued and issuable to the CDS
       stockholders as consideration for the acquisition of $339,250 and the
       legal and other costs incurred in the acquisition of $104,250 have been
       capitalized and were being amortized over an estimated useful life of
       five years. In the second quarter of 1999, based on the results of such
       business since the acquisition and future projections, the Company
       expensed the remaining unamortized acquisition costs of $340,017.

       In February 2000, CDSI announced CDS would no longer actively engage in
       the business of marketing and leasing an inventory control system for
       tobacco products. CDSI determined that CDS could not generate sufficient
       revenues from the sale and leasing of the Coinexx Star 10 to justify
       continuation of the business. The Company did not receive any material
       proceeds from the disposition of the assets of the business.

       In 1998, CDS acquired substantially all of the assets of TD Rowe
       Corporation's New York state cigarette vending route, including vending
       machines, for $59,250. CDS paid $20,000 in 1998 and the remaining $39,250
       in the first quarter of 1999. CDS amortized the costs of the vending
       route over an estimated useful life of five years. In the second quarter
       of 2000, based on the results of the vending route and future projections
       of its fair market value, the Company expensed the remaining unamortized
       acquisition costs of $40,488.

       On October 5, 2000, CDS completed the sale to Gutlove and Shirvint Inc.
       ("Gutlove") of the assets of its cigarette vending route, including
       vending machines and a van. The purchase price for the vending route,
       which is primarily located in New York state, was $34,140 in cash and the
       assumption of a $10,219 note secured by the van. The cash portion of the
       purchase price was based on the cigarette and coin inventory of the
       vending route at the open of business on October 2, 2000, and was paid
       $29,140 on October 5, 2000 with the remaining $5,000 paid on December 1,
       2000.

(4)    THINKDIRECTMARKETING TRANSACTION

       On November 5, 1998, the Company contributed the non-cash assets and
       certain liabilities of the PC411 Service to ThinkDirectMarketing Inc.
       (formerly known as Digital Asset Management,



                                       6

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                                   (UNAUDITED)

       Inc.). ThinkDirectMarketing was organized by Dean Eaker, the former
       President, Chief Executive Officer and director of the Company, and
       Edward Fleiss, the former Vice President and Chief Technology Officer of
       the Company, to continue to operate and develop the PC411 Service. The
       Company received 1,250 shares of preferred stock representing an initial
       42.5% interest in ThinkDirectMarketing in exchange for the contribution
       of the PC411 Service's net assets. Acxiom Corporation ("Acxiom")
       purchased preferred stock representing a 42.5% interest in
       ThinkDirectMarketing for $1,250,000 and initially designated a majority
       of the Board of Directors of ThinkDirectMarketing. ThinkDirectMarketing's
       management, including Messrs. Eaker and Fleiss, held an initial 15%
       interest in ThinkDirectMarketing with options which would have increased
       their ownership position to 50% upon satisfaction of operational and
       financial benchmarks over a three-year period. The Company's carrying
       value in the net assets contributed to ThinkDirectMarketing totaled
       $73,438. The Company recorded $462,360 as a capital contribution in
       connection with the transaction, which represented the Company's 42.5%
       interest in the capital raised by ThinkDirectMarketing in excess of the
       carrying value of the Company's net assets contributed to
       ThinkDirectMarketing. The Company agreed, under certain conditions, to
       fund up to $200,000 of an $800,000 working capital line to be provided to
       ThinkDirectMarketing by Acxiom, the Company and Dean Eaker. The Company
       funded $100,000 of the working capital line in the second quarter of
       1999.

       From July 1999 to September 2000, ThinkDirectMarketing issued
       approximately $3,112,000 of convertible notes and warrants to purchase
       ThinkDirectMarketing preferred stock. In connection with such issuances,
       Mr. Eaker and Acxiom have agreed to extend the maturity of their working
       capital lines from June 30, 1999 to December 31, 2001 and have received
       warrants to purchase preferred shares. The Eaker and Acxiom working
       capital lines are also convertible into ThinkDirectMarketing preferred
       stock. The Company agreed in July 1999 to extend the maturity of its
       working capital line from June 30, 1999 to August 31, 1999 and was
       released from any further obligation to fund additional amounts under the
       working capital line.

       In October 2000, ThinkDirectMarketing and VoyagerIT.com PLC
       ("VoyagerIT.com") entered into an agreement where VoyagerIT.com purchased
       shares of convertible preferred stock for $1,000,000 (the "VoyagerIT.com
       Preferred Stock") and agreed to purchase $4,000,000 of convertible notes
       the "Notes") on various dates between November 10, 2000 and June 8, 2001.
       ThinkDirectMarketing's management has informed the Company that
       VoyagerIT.com has completed its scheduled purchases of $4,000,000 of the
       Notes. In connection with the completion of VoyagerIT.com's scheduled
       purchase of the Notes in February 2001, ThinkDirectMarketing converted
       $3,312,000 of its notes into various classes of preferred stock ranking
       pari passu with CDSI's preferred stock. At June 30, 2001, the aggregate
       stated liquidation preference of ThinkDirectMarketing's preferred stock
       was $6,852,000, of which $1,250,000 was owned by CDSI. Also, at June 30,
       2001, ThinkDirectMarketing had notes payable due to Acxiom and
       VoyagerIT.com of $400,000 and $3,110,000, respectively. In connection
       with the agreement to purchase the VoyagerIT.com Preferred Stock and the
       Notes, ThinkDirectMarketing granted VoyagerIT.com an option to acquire
       the remaining shares of ThinkDirectMarketing's stock for $20 million,
       subject to downward adjustment if certain targets

                       CDSI HOLDINGS INC. AND SUBSIDIARIES

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                                   (UNAUDITED)

       related to revenue, subscriptions, number of clients, expenses and net
       income are not met on or before October 31, 2001 (which may be extended
       under certain circumstances to March 31, 2002).

       In connection with such agreements, the Company agreed to extend the
       maturity of its working capital line from August 31, 1999 until the
       earlier of June 8, 2001 or the date on which VoyagerIT.com does not close
       on any of its scheduled purchases of the Notes. In June 2001,
       VoyagerIT.com completed its scheduled purchases and the Company's note
       receivable was repaid. The Company's interest in ThinkDirectMarketing
       would decrease to approximately 6% assuming the conversion and exercise
       of all notes and warrants issued in the above transactions.

       ThinkDirectMarketing has incurred significant losses and negative cash
       flow since its inception and currently has only limited cash resources.
       ThinkDirectMarketing requires a significant amount of additional capital
       to continue its operations and to develop its business. No assurance can
       be given that VoyagerIT.com will exercise its option to acquire
       ThinkDirectmarketing or that ThinkDirectMarketing will achieve the
       targets stated in the option agreement. As a result, there is a
       substantial risk that ThinkDirectMarketing will not be able to raise
       sufficient additional capital to continue its operations or, if
       ThinkDirectMarketing is able to raise additional capital that the
       Company's ownership percentage will be diluted.

       The Company has accounted for its non-controlling interest in
       ThinkDirectMarketing using the equity basis of accounting since November
       5, 1998. The Company's equity in ThinkDirectMarketing's losses for the
       year ended December 31, 1999 was adjusted to reflect the difference in
       the Company's contribution of its net assets to ThinkDirectMarketing and
       the fair value of those assets recorded by ThinkDirectMarketing. In the
       second quarter of 1999, the carrying value of the Company's investment in
       ThinkDirectMarketing, including the $100,000 note receivable, was reduced
       to zero as the cumulative equity in ThinkDirectMarketing's losses
       exceeded the Company's investment in ThinkDirectMarketing of $635,798,
       which consisted of the initial carrying value of $535,798 and the
       $100,000 working capital loan to ThinkDirectMarketing. Since the Company
       has no intention or commitment to fund future ThinkDirectMarketing
       losses, commencing in the second quarter of 1999, the Company suspended
       recognizing its share of the additional losses of ThinkDirectMarketing.
       The Company recorded income of $100,000 in the second quarter in
       connection with the repayment of the $100,000 note receivable from
       ThinkDirectMarketing.

 (5)   RELATED PARTY TRANSACTIONS

       Certain accounting and related finance functions are performed on behalf
       of the Company by employees of New Valley Corporation, the principal
       stockholder of the Company. Expenses incurred relating to these functions
       are allocated to the Company and paid as incurred to New Valley based on
       management's best estimate of the cost involved. The amounts allocated
       were immaterial for all periods presented herein.

(6)    NET INCOME (LOSS) PER SHARE

       Basic income (loss) per share of common stock is computed by dividing net
       loss applicable to common stockholders by the weighted average shares of
       common stock outstanding during the period (3,120,000 shares). Diluted
       per share results reflect the potential dilution from the exercise or
       conversion of securities into common stock.

       Stock options and warrants (both vested and non-vested) totaling
       2,979,288 shares at June 30, 2001 and 2000, respectively, were excluded
       from the calculation of diluted per share results presented because their
       effect was anti-dilutive. Accordingly, diluted net income (loss) per
       common share is the same as basic net loss per common share.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

OVERVIEW

         The Company owns 100% of the issued and outstanding shares of common
stock of CDS and an approximate 6% interest on a fully diluted basis in
ThinkDirectMarketing. In February 2000, the Company terminated all operations
relating to marketing and leasing the Coinexx Star 10 inventory control system.
In October 2000, CDS sold the assets of its cigarette vending route, the only
current source of revenue for CDS and the Company.

         The Company intends to seek new Internet-related businesses or other
business opportunities. As the Company has only limited cash resources, the
Company's ability to complete any acquisition or investment opportunities it may
identify will depend on its ability to raise additional financing, as to which
there can be no assurance. As of the date of this report, the Company has not
identified any potential acquisition or investment. There can be no assurance
that the Company will successfully identify, complete or integrate any future
acquisition or investment, or that acquisitions or investments, if completed,
will contribute favorably to its operations and future financial condition.

CDS

         CDS was acquired in May 1998. Under the terms of the acquisition, the
former stockholders of CDS received an aggregate of 147,500 shares of Common
Stock at closing. In addition, the former stockholders were to receive an
additional 147,500 shares of Common Stock on each of May 8, 2000, 2001 and 2002
so long as CDS was actively engaged in the business of marketing and leasing the
Coinexx Star 10 inventory control system. As CDS is no longer actively engaged
in that business, the contingent shares of Common Stock will not be issued to
the former stockholders of CDS.

       CDS did not have any significant tangible assets at the time of
acquisition. The fair value of the Common Stock issued and issuable to the CDS
stockholders as consideration for the acquisition of $339,250 and the legal and
other costs incurred in connection with the acquisition of $104,250 have been
capitalized and were being amortized over a five-year period. In the second
quarter of 1999, based on the results of the business since the acquisition and
future projections, the Company expensed the remaining unamortized acquisition
costs of $340,017.

       In 1998, CDS acquired substantially all of the assets of TD Rowe
Corporation's New York state cigarette vending route, including vending
machines, for $59,250. CDS paid $20,000 in 1998 and the remaining $39,250 in the
first quarter of 1999. CDS amortized the costs of the vending route over an
estimated useful life of five years. In the second quarter of 2000, based on the
results of the vending route and future projections of its fair market value,
the Company expensed the remaining unamortized acquisition costs of $40,488.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS - (CONTINUED)


       On October 5, 2000, CDS completed the sale to Gutlove of the assets of
its cigarette vending route, including vending machines and a van. The purchase
price for the vending route, which is primarily located in New York state, was
$34,140 in cash and the assumption of a $10,219 note secured by the van. The
cash portion of the purchase price was based on the cigarette and coin inventory
of the vending route at the open of business on October 2, 2000, and was paid
$29,140 on October 5, 2000 with the remaining $5,000 paid on December 1, 2000.

THINKDIRECTMARKETING

         On November 5, 1998, the Company contributed substantially all the
non-cash assets and certain liabilities related to its on-line electronic
delivery information service to ThinkDirectMarketing. See Note 4 to the
financial statements for additional information concerning the Company's
investment in ThinkDirectMarketing.

       The Company's interest in ThinkDirectMarketing is accounted for using the
 equity method of accounting. Commencing in the second quarter of 1999, the
 carrying value of the Company's investment in ThinkDirectMarketing was reduced
 to zero, and the Company suspended recognizing its share of the additional
 losses of ThinkDirectMarketing. In the second quarter of 2001,
 ThinkDirectMarketing repaid a $100,000 note receivable due to the Company. As a
 result, CDS recorded $100,000 of income associated with the repayment.

RESULTS OF OPERATIONS

         For the three and six months ended June 30, 2001 and 2000, the results
of operations of CDS, the Company's primary operating unit, were as follows:

CDS

         REVENUES. CDS had revenues of $105,047 and $177,030 for the three and
six months ended June 30, 2000. The revenues for the three-month period resulted
from sales of cigarettes. The revenues for the six-month period resulted from
the following: $1,102 from machine leases, $8,162 from machine sales and
$167,766 from the sales of cigarettes.

         COST OF REVENUES. Cost of revenues of $94,573 and $150,483 for CDS for
the three and six months ended June 30, 2000, respectively, consisted primarily
of costs of cigarettes of $94,573 and $140,398. Cost of revenues also included
warehouse expenses and shipping of machines held for lease. CDS depreciated its
machines held for lease over five years once the asset was placed in service.

         SALES AND MARKETING EXPENSES. Sales and marketing expenses for CDS were
$6,458 and $22,580 for the three and six months ended June 30, 2000,
respectively. The expenses consisted primarily of personnel costs.

         GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative
expenses for CDS were $31,251 and $105,749 for the three and six months ended
June 30, 2000, respectively. The expenses consisted primarily of payroll,
consulting and office expenses.

         AMORTIZATION OF INTANGIBLE ASSETS. CDS amortized its intangible assets
over a 60-month life. In the second quarter of 2000, based on the results of the
vending route and future projections of its fair market value, the Company
expensed the remaining unamortized acquisition costs of $40,488.

CORPORATE AND OTHER

         Expenses associated with corporate activities were $16,278 and $35,681
for the three and six months ended June 30, 2001, respectively, as compared to
$2,809 and $16,096 for the same periods in the prior year. The expenses were
primarily associated with costs necessary to maintain a public company.

OTHER INCOME (EXPENSE)

         Interest and other income was $1,933 and $5,008 for the three and six
months ended June 30, 2001, compared to $2,130 and $5,192 for the three and six
months ended June 30, 2000. The decrease is principally related to lower
interest rates in 2001 offset by higher cash balances. CDS recorded $100,000 in
income in the second quarter of 2001 relating to the repayment of a loan
receivable from ThinkDirectMarking. The carrying value of the loan had been
reduced to zero in the second quarter of 1999 when CDS suspended recognizing its
share of the additional losses of ThinkDirectMarketing.

LIQUIDITY AND CAPITAL RESOURCES

         The Company has limited available cash, limited cash flow, limited
liquid assets and no credit facilities. The Company has not been able to
generate sufficient cash from operations and, as a consequence, financing has
been required to fund ongoing operations. Since completion of the Company's
initial public offering of its common stock (the "IPO") in May 1997, the Company

has primarily financed its operations with the net proceeds of the IPO. The
funds were used to complete the introduction of the PC411 Service over the
Internet, to expand marketing, sales and advertising, to develop or acquire new
services or databases, to acquire CDS and for general corporate purposes.

         Cash used for operations for the six months ended June 30, 2001 and
2000 was $65,474 and $133,409, respectively. The decrease is primarily due to a
decreased operating loss of $140,304 offset by lower amortization expense of
$45,491.

         Capital expenditures of $900 for the six months ended June 30, 2000
consisted primarily of the purchase of office equipment. The Company does not
expect significant capital expenditures during the year ended December 31, 2001.

         At June 30, 2001, the Company had cash and cash equivalents of
$287,713. The Company does not currently have any commitments for any additional
financing, and there can be no assurance that any such commitments can be
obtained. Any additional equity financing may be dilutive to its existing
stockholders, and debt financing, if available, may involve pledging some or all
of its assets and may contain restrictive covenants with respect to raising
future capital and other financial and operational matters.

         Inflation and changing prices had no material impact on revenues or the
results of operations for the six months ended June 30, 2001 and 2000.

         Management is currently evaluating alternatives to supplement the
Company's present cash and cash equivalents to meet its liquidity requirements
over the next twelve months. Such alternatives include seeking additional
investors and/or lenders and disposing of the interest in ThinkDirectMarketing.
Although there can be no assurance, the Company believes that it will be able to
continue as a going concern for the next twelve months.

         ThinkDirectMarketing has incurred significant losses and negative cash
flow since its inception and currently has only limited cash resources.
ThinkDirectMarketing requires a significant amount of additional capital to
continue its operations and to develop its business. As a result, there is a
substantial risk that ThinkDirectMarketing will not be able to raise sufficient
additional capital to continue its operations or, if ThinkDirectMarketing is
able to raise additional capital that the Company's ownership percentage will be
diluted.

         The Company or its affiliates, including New Valley, may, from time to
time, based upon present market conditions, purchase shares of the Common Stock
in the open market or in privately negotiated transactions.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         The Company and its representatives may from time to time make oral or
written "forward-looking statements" within the meaning of the Private
Securities Reform Act of 1995 (the "Reform Act"), including any statements that
may be contained in the foregoing "Management's Discussion and Analysis of

Financial Condition and Results of Operations", in this report and in other
filings with the Securities and Exchange Commission and in its reports to
stockholders, which represent the Company's expectations or beliefs with respect
to future events and financial performance. These forward-looking statements are
subject to certain risks and uncertainties and, in connection with the
"safe-harbor" provisions of the Reform Act, the Company has identified under
"Risk Factors" in Item 1 of the Company's Form 10-KSB for the year ended
December 31, 2000 filed with the Securities and Exchange Commission and in this
section important factors that could cause actual results to differ materially
from those contained in any forward-looking statements made by or on behalf of
the Company.

         The Company's plans and objectives are based, in part, on assumptions
involving judgments with respect to, among other things, future economic,
competitive and market conditions and future business decisions, all of which
are difficult or impossible to predict accurately and many of which are beyond
the control of the Company. Although the Company believes that its assumptions
underlying the forward-looking statements are reasonable, any of the assumptions
could prove inaccurate and, therefore, there can be no assurance that the
forward-looking statements included in this report will prove to be accurate. In
light of the significant uncertainties inherent in the forward-looking
statements included herein, particularly in view of the Company's limited
operations, the inclusion of such information should not be regarded as a
representation by the Company or any other person that the objectives and plans
of the Company will be achieved. Readers are cautioned not to place undue
reliance on such forward-looking statements, which speak only as of the date on
which such statements are made. The Company does not undertake to update any
forward-looking statement that may be made from time to time on its behalf.
