                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

DualStar Technologies Corporation ("DualStar" or the "Company"), through its
wholly owned subsidiaries, operates two separate lines of business: (a)
construction and (b) communications.

The Company has continued to further curtail its communications business. Its
communications segment is now primarily limited to the subscription video
business in the New York City metropolitan area and in Florida. The Company's
communications segment's telephone service business was discontinued in August
2002. The effects of the discontinuation of the business are immaterial and
thus, presentation as discontinued operations is not considered necessary.

In addition, the Company has sold certain communications assets in locations
outside of the New York City metropolitan area and Florida. In April 2002, the
Company sold certain communications assets for $0.4 million. The transaction
resulted in a loss of $0.5 million. In August 2002, the Company sold certain
access agreements on properties located in the Los Angeles area and the
communications assets located in the properties for $0.4 million. The
transaction resulted in a gain of $0.1 million.

Due to the Company's continuing re-focus and resulting curtailment of its
communications business efforts and resources, a $2.5 million charge for the
impairment of certain remaining communications assets was recorded in fiscal
year 2002. Additionally, the Company evaluated its network infrastructure
equipment during the previous quarter by comparing the net book value of the
assets to their fair market value and determined there was an impairment loss of
$700,000. Such loss is reflected in the accompanying condensed consolidated
statement of operations for the nine months ended March 31, 2003. In January
2003, the Company sold the network infrastructure assets in conjunction with its
exit out of the Internet service business for a nominal amount. The net book
value of the assets sold was $587,104. A gain of $112,897 on the sale of these
assets, due to the recovery of an over-impairment in the previous quarter, is
reflected in the accompanying condensed consolidated statement of operations for
the three months ended March 31, 2003.

The Company incurred significant losses in the last several fiscal years,
primarily in the communications segment, and it expects that the communications
segment, even significantly limited, will continue to incur losses going forward
and will require additional capital to fund those losses. The Company has
implemented and will continue to implement cost reductions designed to minimize
such losses. There can be no assurance that these efforts will be successful or
that the construction segment will sustain profitability or positive cash flow
from future operations or that positive cash flow, if any, will be sufficient to
offset continued losses from the communications segment. Given the current U.S.
economic climate, market conditions and the financial condition of the Company,
there is a substantial likelihood that the Company will be unable to raise
additional funds on terms satisfactory to it, if at all, to fund the expected
operating losses. Moreover, the Company presently owes Madeleine L.L.C.
("Madeleine") approximately $16.3 million and is in default under the loan
(described below). Madeleine may call the loan due and payable at any time, and,
if it is not paid, foreclose on significant assets of the Company's subsidiaries
that secure such loan. If the Company cannot raise additional funds or if
Madeleine demands payment on its loan, the Company will likely be forced to
cease operations. Accordingly, there is substantial doubt about the Company's
ability to continue as a going concern.

In November 2000, the Company consummated a $12.5 million senior secured loan
transaction with Madeleine, an affiliate of Blackacre Capital Management L.L.C.
("Blackacre") (the "Madeleine Loan"). The Madeleine Loan, which is due and
payable in November 2007, bears interest at a fixed rate of 11% per annum. The
Madeleine Loan is a senior secured obligation of the Company and is guaranteed
by certain subsidiaries of the Company, which have pledged

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


substantially all of their respective assets to collateralize such guarantee. In
connection with the Madeleine Loan, the Company issued warrants to purchase
3,125,000 shares of common stock at an exercise price of $4.00 per share,
subject to antidilution provisions, expiring in December 2007, to an affiliate
of Madeleine. A portion of the Madeleine Loan proceeds was used to retire
existing indebtedness of the Company in the principal amount of $7 million owed
to Madeleine and to pay expenses of obtaining the Madeleine Loan. The remaining
proceeds were used for the Company's working capital purposes. No value was
allocated to the warrants because the value was deemed immaterial.

The Company has not made payments to Madeleine pursuant to the Madeleine Loan
agreement. The de-listing of the Company's common shares from the Nasdaq
National Market has also created a default under the Madeleine Loan agreement.
In August 2002, the Company, Blackacre and Madeleine began negotiating, with a
view towards reducing the Madeleine Loan by selling certain of the Company's
communications assets to Blackacre at fair market value and by converting the
remaining Madeleine Loan balance to stock of the Company. In November 2002, the
Company announced that it entered into a letter of intent with Madeleine under
which Madeleine or its designee would purchase substantially all the assets of
ParaComm Inc. The assets to be acquired are ParaComm's private cable television
systems and associated assets related to its principal properties in the State
of Florida. The purchase price will be satisfied by a reduction of principal in
the amount of $3,000,000 plus a reduction of related accrued and unpaid
interest on the note. The ParaComm sale to Madeleine is subject to the execution
of a definitive purchase agreement, receipt of a fairness opinion from an
independent financial advisor and the approval of the transaction by the
Company's Board of Directors. There is no assurance that the Company, Blackacre
and Madeleine will be able to reach definitive agreement or that they will reach
agreement with respect to further elimination or reduction of the Madeleine
Loan.

The Company presently owes Madeleine approximately $16.3 million under the
Madeleine Loan and is in default under the Madeleine Loan agreement. Madeleine
has the right to call the loan due and payable at any time. If Madeleine were to
demand payment, the Company would be unable to make such payment. In such an
event, Madeleine would have the right to foreclose on significant assets of the
Company that collateralize the Madeleine Loan. Such foreclosure would result in
the Company being unable to continue in business.

Due to the downturn affecting corporate America, the bonding industry has come
under increased pressure and claims, and in general, the bonding market has
tightened. Consequently, it has become more difficult for the Company to secure
surety bonds due to the Company's financial position and overall market
conditions. The Company is currently considering ways to improve its ability to
obtain bonding. There can be no assurance that the Company will be able to
obtain bonding or, if so, at a reasonable cost. If the Company is unable to
obtain surety bonds as needed, this may have a material adverse effect on the
Company.


NOTE A - BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include certain information and
disclosures required by accounting principles generally accepted in the

NOTE A  (CONTINUED)


United States of America for complete consolidated financial statements. In the
opinion of management, all adjustments considered necessary for a fair
presentation have been included and are of normal and recurring nature.
Operating results for the three and nine-month periods ended March 31, 2003 are
not necessarily indicative of the results that may be expected for the fiscal
year ending June 30, 2003. The interim statements should be read in conjunction
with the financial statements and notes, thereto included in the Company's
Annual Report on Form 10-K for the fiscal year ended June 30, 2002.

NOTE B - PER SHARE DATA

The computation of basic and diluted net income (loss) per share is based on the
weighted average number of shares of common stock outstanding. For diluted net
loss and income per share, when dilutive, stock options and warrants are
included as share equivalents using the treasury stock method, and shares
available for conversion under the convertible note are included as if converted
at the date of issuance. For the three and nine months ended March 31, 2003 and
2002, respectively, stock options and warrants have been excluded from the
calculation of diluted loss per share as their effect would have been
antidilutive.

NOTE C - CONTINGENCIES

(a) Until 1995, Centrifugal was a partner with DAK Electric Contracting Corp.
("DAK") in a joint venture that performed mechanical and electrical services for
a general contractor on a construction project in Manhattan known as the Lincoln
Square project. Centrifugal was responsible for the mechanical portion of the
contract, and its co-venturer, DAK, was responsible for the electrical portion.
In 1995, DAK became insolvent, thereby obligating Centrifugal to complete the
work on this project. As a result, in fiscal 1996 the Company wrote off
approximately $3.7 million with respect to accounts receivable, loans
receivable, claims and other costs that the Company incurred on behalf of DAK in
fulfillment of DAK's obligations under the contract on the Lincoln Square
project.

As of June 30, 1996, all of the known claims and liens of subcontractors of the
joint venture were settled and discharged, and all of the vendor lawsuits which
arose out of these claims were also settled with the exception of the following:
The joint venture's bonding companies have claims over for indemnity against
Centrifugal and under a guarantee agreement against the Company in the event
that a judgment is rendered against the bonding companies in a suit brought by
an employee benefit fund for DAK's employees' union seeking contributions to the
fund which the fund claims were due but not paid by DAK. The complaint alleges
several causes of action against several defendants in connection with several
projects and seeks a total of approximately $450,000 in damages on all of these
causes against the named defendants; however, only one of the several causes of
action, which seeks an unspecified portion of the total damages demanded,
relates to the Company. In February 2003, the Company was informed that the
bonding company reached a settlement with the union on account of the claim for
unpaid benefits on the Lincoln Square project in the amount of $270,000. The
bonding company expressed its intent to pursue reimbursement for such settlement
amount through the cross-claims alleged against the Company in such action.
Additionally, the Company may be exposed to such legal fees and other expenses
as the Company's bonding company may have incurred or will incur in connection
with this claim. Centrifugal and the Company have asserted, among other
defenses, that such contributions were not guaranteed under the terms of the
joint venture's bonds.

NOTE C (CONTINUED)

 (b) In August 2001, OnTera signed a promissory note and security agreement with
Nokia to finance the purchase of various network equipment totaling
approximately $668,000. The note bears interest at a rate of 11% per annum and
requires eighteen monthly installments effective April 1, 2001. The note is
secured by the network equipment financed by the note. OnTera has not made
monthly installments since June 2001, therefore the Company is in default of the
agreement. As such, the remaining balance at March 31, 2003 of $564,370 is
included in accrued expenses and other current liabilities. In August 2002,
Nokia filed suit in the District Court of Dallas County, Texas, claiming damages
of approximately $607,000 plus interest, costs and attorneys on the promissory
note.

(c) In 1999, ParaComm purchased from Golden Sky Systems (GSS) GSS's contract
with DirecTV which authorized it to be a DirecTV Master Systems Operator (MSO).
Along with the contract so purchased, ParaComm acquired a GSS contract with one
of its System Operators, Cable America, Inc. In May, 2002 Cable America, Inc.
filed suit in the Circuit Court of Cook County, Illinois against ParaComm,
OnTera, DirecTV, GSS and Pegasus Communications Inc., which had subsequently
acquired GSS. The suit claims damages for allegedly unpaid commissions in the
claimed amount of $339,000 and also seeks an accounting.

(d) In July 2002, plaintiff Harvey Wayne filed a verified shareholders'
derivative complaint against directors and officers of the Company, various
other entities and the Company as a nominal defendant, in the United States
District Court for the Eastern District of New York. The complaint alleges
breach of fiduciary duties and seeks to compel the Company to hold a
shareholders' meeting for the election of directors. The complaint seeks
injunctive relief and unspecified damages. Motions to dismiss have been filed by
the Company and other defendants and are pending before the Court.

(e) In the ordinary course of business, the Company is involved in claims
concerning personal injuries and property damage, all of which the Company
refers to its insurance carriers. The Company believes that the claims are
covered under its liability policies and that no loss to the Company is
probable. No provision for such claims has been made in the accompanying
financial statements.

NOTE D - SEGMENT INFORMATION

The Company has the following two reportable segments: construction and
communications. The construction segment primarily provides electrical and
mechanical contracting services in the New York Metropolitan area. The
communications segment primarily provides cable television services to buildings
in New York City and Florida.

The accounting policies used to develop segment information correspond to those
disclosed in the Company's Annual Report on Form 10-K for the fiscal year ended
June 30, 2002. The Company does not allocate certain corporate expenses incurred
by the parent company to its segments. Segment profit (loss) is based on profit
(loss) from operations before income taxes (benefits) and does not include those
corporate expenses incurred by the parent company. Sales and transfers between
segments are accounted for at cost. The reportable segments are distinct
business units operating in different industries. They are separately managed,
with separate marketing systems.

NOTE E - DEBT

Senior Secured Promissory Note


In November 2000, the Company consummated a $12.5 million senior secured loan
transaction with Madeleine, an affiliate of Blackacre Capital Management L.L.C.
("Blackacre") (the "Madeleine Loan"). The Madeleine Loan, which is due and
payable in November 2007, bears interest at a fixed rate of 11% per annum. The
Madeleine Loan is a senior secured obligation of the Company and is guaranteed
by certain subsidiaries of the Company, which have pledged substantially all of
their respective assets to collateralize such guarantee. In connection with the
Madeleine Loan, the Company issued warrants to purchase 3,125,000 shares of
common stock at an exercise price of $4.00 per share, subject to antidilution
provisions, expiring in December 2007, to an affiliate of Madeleine. A portion
of the Madeleine Loan proceeds was used to retire existing indebtedness of the
Company in the principal amount of $7 million owed to Madeleine and to pay
expenses of obtaining the Madeleine Loan. The remaining proceeds were used for
the Company's working capital purposes. No value was allocated to the warrants
because the value was deemed immaterial.

The Company has not made payments to Madeleine pursuant to the Madeleine Loan
agreement. The de-listing of the Company's common shares from the Nasdaq
National Market has also created a default under the loan agreement. In August
2002, the Company, Blackacre and Madeleine began negotiating, with a view
towards reducing the Madeleine Loan by selling certain of the Company's
communications assets to Blackacre at fair market value and by converting the
remaining Madeleine Loan balance to stock of the Company. In November 2002, the
Company announced that it entered into a letter of intent with Madeleine under
which Madeleine or its designee would purchase substantially all the assets of
ParaComm Inc. The assets to be acquired are ParaComm's private cable television
systems and associated assets related to its principal properties in the State
of Florida. The purchase price will be satisfied by a reduction of principal in
the amount of $3,000,000 plus a reduction of related accrued and unpaid
interest on the note. The ParaComm sale to Madeleine is subject to the execution
of a definitive purchase agreement, receipt of a fairness opinion from an
independent financial advisor and the approval of the transaction by the
Company's Board of Directors. There is no assurance that the Company, Blackacre
and Madeleine will be able to reach definitive agreement or that they will reach
agreement with respect to further elimination or reduction of the Madeleine
Loan.

The Company presently owes Madeleine approximately $16.3 million under the
Madeleine Loan and is in default under the Madeleine Loan agreement. Madeleine
has the right to call the loan due and payable at any time. If Madeleine were to
demand payment, the Company would be unable to make such payment. In such an
event, Madeleine would have the right to foreclose on significant assets of the
Company that collateralize the Madeleine Loan. Such foreclosure would result in
the Company being unable to continue in business.

Mortgage Payable

In March 2003, the Company paid off its mortgage in the amount of $1,693,885.

NOTE F - NEW ACCOUNTING STANDARDS ADOPTED

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based
Compensation - Transition and Disclosure - an amendment of FASB Statement No.
123." SFAS No. 148 amends SFAS No. 123, "Accounting for Stock-Based
Compensation," to provide alternative

NOTE F  (CONTINUED)

methods of transition for a voluntary change to the fair value based method of
accounting for stock-based employee compensation. In addition, SFAS No. 148
amends the disclosure requirements of SFAS No. 123 to require prominent
disclosures in both annual and interim financial statements about the method of
accounting for stock-based employee compensation and the effect of the method
used on reported results. The disclosure requirements apply to all companies for
fiscal years ending after December 15, 2002. The interim disclosure provisions
are effective for financial reports containing financial statements for interim
periods beginning after December 15, 2002. The adoption of SFAS No. 148 is not
expected to have a material impact on the Company's financial statements.

NOTE G - NEW ACCOUNTING STANDARDS NOT YET ADOPTED

In June 2002, the FASB issued SFAS No.146, "Accounting for Costs Associated with
Exit or Disposal Activities." SFAS No. 146 addresses financial accounting and
reporting for costs associated with exit or disposal activities and nullified
Emerging Issues Task Force Issue No. 94-3, "Liability Recognition for Certain
Employee Termination Benefits and Other Costs to Exit an Activity (including
Certain Costs Incurred in a Restructuring)." SFAS No. 146 requires that a
liability for a cost associated with an exit or disposal activity be recognized
when the liability is incurred. A fundamental conclusion reached by the FASB in
this statement is that an entity's commitment to a plan, by itself, does not
create a present obligation to others that meets the definition of a liability.
SFAS No. 146 also establishes that fair value is the objective for initial
measurement of the liability. The provisions of this statement are effective for
exit or disposal activities that are initiated after March 31, 2003, with early
application encouraged. The Company has not yet determined the impact of SFAS
No.146 on its financial position and results of operations, if any.

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

GENERAL

DualStar Technologies Corporation ("DualStar" or the "Company"), through its
wholly owned subsidiaries, operates two separate lines of business: (a)
construction businesses; and (b) communications businesses. For a description of
the Company's businesses and operations, see Item 1 of the Company's Annual
Report on Form 10-K, for the fiscal year ended June 30, 2002. The statements
contained in this Quarterly Report on Form 10-Q, including the exhibits hereto,
relating to operations of DualStar Technologies Corporation and its subsidiaries
(DualStar or the Company) may constitute forward-looking statements within the
meaning of Section 21E of the Securities Exchange Act of 1934, as amended.
Please note that the words intends, expects, plans, estimates, projects,
believes, anticipates and similar expressions are intended to identify
forward-looking statements. Actual results of the Company may differ materially
from those in the forward-looking statements and may be affected by a number of
factors including the Company's ability to continue operations, including if
Madeleine L.L.C. were to call its loan, the ability of the Company's
communications segment to continue to implement its cost reduction plan, the
ability of the Company to raise and provide the capital resources to fund the
continuing communications operating losses, the Company's ability to obtain
bonding or insurance coverage, regulatory or legislative changes, the Company's
dependence on key personnel, and the Company's ability to manage growth, in
addition to those risk factors, set forth in the section captioned "Risk
Factors" and the assumptions, risks and uncertainties set forth in the other
sections of the Company's Annual Report on Form 10-K for the fiscal year ended
June 30, 2002 as well as in DualStar's other filings with the SEC. The Company
can give no assurance that its plans, intentions, and expectations will be
achieved and actual results could differ materially from forecasts and
estimates.

Due to the downturn affecting corporate America, the bonding industry has come
under increased pressure and claims, and in general, the bonding market has
tightened. Consequently, it has become more difficult for the Company to secure
surety bonds due to the Company's financial position and overall market
conditions. The Company is currently considering ways to improve its ability to
obtain bonding. There can be no assurance that the Company will be able to
obtain bonding or, if so, at a reasonable cost. If the Company is unable to
obtain surety bonds as needed, this may have a material adverse effect on the
Company.

CAPITAL RESOURCES AND LIQUIDITY

Cash balances at March 31, 2003 and June 30, 2002 were $2.8 million and $2.5
million, respectively. The Company was provided with $1.7 million of cash in the
nine months ended March 31, 2003 by operating activities. The net cash provided
by operating activities was primarily due to decrease in receivables of the
construction businesses. In the nine months ended March 31, 2002, the Company
used net cash of $2.5 million in operating activities to fund the operating loss
incurred by the communications segment. The Company's operating cash flows are
primarily generated from the construction segment. Due to the relatively high
dollar value of each construction contract, generally ranging from $3 million to
$10 million, should the collection of contract receivables be delayed, the
Company's operations may be materially adversely affected.

The Company incurred significant losses in the last several fiscal years,
primarily in the communications segment, and it expects that the communications
segment will continue to incur losses going forward and will require additional
capital to fund those losses. The Company has implemented and will continue to
implement cost reductions designed to minimize such losses. There can be no
assurance that these efforts will be successful or that the construction segment
will sustain profitability or positive cash flow from future operations or that
any positive cash flow will be sufficient to offset continued losses from the
communications segment. Given the current U.S. economic climate and market
conditions and the financial condition of the Company, there is a substantial
likelihood that the Company will be unable to raise additional

<PAGE>

funds on terms satisfactory to it, if at all, to fund the expected operating
losses. Moreover, the Company presently owes Madeleine approximately $16.3
million and is in default under the loan. Madeleine may call the loan due and
payable at any time, and, if it is not paid, foreclose on significant assets of
the Company's subsidiaries that secure such loan. If the Company cannot raise
additional funds or if Madeleine demands payment on its loan, the Company will
likely be forced to cease operations. Accordingly, there is substantial doubt
about the Company's ability to continue as a going concern.

In November 2000, the Company consummated a $12.5 million senior secured loan
transaction with Madeleine, an affiliate of Blackacre Capital Management L.L.C.

Construction revenue decreased $4.0 million or 21.3% from $18.8 million in the
three months ended March 31, 2002 to $14.8 million in the three months ended
March 31, 2003. The decrease was primarily due to fewer and smaller construction
contracts.

Construction revenue decreased $11.3 million or 20.8% from $54.4 million in the
nine months ended March 31, 2002 to $43.1 million in the nine months ended March
31, 2003. The decrease was primarily due to fewer and smaller construction
contracts.

Cost of construction revenue decreased $5.6 million or 33.1% from $16.9 million
in the three months ended March 31, 2002 to $11.3 million in the three months
ended March 31, 2003. The decrease was primarily due to the decrease in
construction revenue. Gross profit percentages were 23.6% and 10.1% in the three
months ended March 31, 2003 and 2002, respectively. The improvement in gross
profit percentage was due primarily to a higher gross margin percentage in the
new contracts.

Cost of construction revenue decreased $12.9 million or 26.7% from $48.3 million
in the nine months ended March 31, 2002 to $35.4 million in the nine months
ended March 31, 2003. The decrease was primarily due to the decrease in
construction revenue. Gross profit percentages were 17.9% and 11.2% in the nine
months ended March 31, 2003 and 2002, respectively. The

<PAGE>

improvement in gross profit percentage was due primarily to a higher gross
margin percentage in the new contracts.

Construction operating income increased $1.1 million or 366.7% from $0.3 million
in the three months ended March 31, 2002 to $1.4 million for the three months
ended March 31, 2003. The increase was due primarily to higher gross margins in
the new contracts.

Construction operating income increased $0.8 million or 57.1% from $1.4 million
in the nine months ended March 31, 2002 to $2.2 million for the nine months
ended March 31, 2003. The increase was due primarily to higher gross margins in
the new contracts.

Communications revenue decreased $0.6 million or 66.7% from $0.9 million in the
three months ended March 31, 2002 to $0.3 million in the three months ended
March 31, 2003. Communications revenue decreased $1.5 million or 57.7% from $2.6
million in the nine months ended March 31, 2002 to $1.1 million in the nine
months ended March 31, 2003. The decreases were due primarily to the
discontinuance of the Company's telephone and Internet service businesses.

Cost of communications revenue decreased $0.3 million or 60.0% from $0.5 million
in the three months ended March 31, 2002 to $0.2 million in the three months
ended March 31, 2003. The decrease was primarily due to the decrease in revenue.
Gross profit percentages were 33.3% and 44.4% in the three months ended March
31, 2003 and 2002, respectively. The decrease was due primarily to the
recognition of direct costs attributable to the termination of the Internet
service business.

Cost of communications revenue decreased $0.8 million or 57.1% from $1.4 million
in the nine months ended March 31, 2002 to $0.6 million in the nine months ended
March 31, 2003. The decrease was due primarily to the decrease in revenue. Gross
profit percentages were 45.5% and 46.2% in the nine months ended March 31, 2003
and 2002, respectively. The decrease was due primarily to the recognition of
direct costs attributable to the termination of the telephone and Internet
service businesses.

Operating loss of the communications segment decreased $3.1 million or 86.1%
from ($3.6) million in the three months ended March 31, 2002 to ($0.5) million
in the three months ended March 31, 2003. Operating loss of the communications
segment decreased $4.0 million or 65.6% from ($6.1) million in the nine months
ended March 31, 2002 to ($2.1) million in nine months ended March 31, 2003.
Included in the nine months ended March 31, 2003 is a $0.7 million impairment
charge related to the sale of the Internet business.

The improvement in lowering the operating loss of the communications segment was
due primarily to the Company's decision to further limit its communications
business efforts and resources to the subscription video business in the New
York City metropolitan area and in Florida. The Company's communications
segment's telephone service business was discontinued in August 2002. The
Company is presently engaged in negotiating to sell substantially all of its
assets in Florida. There can be no assurance that the Company will be able to
raise and provide the capital resources to fund the expected communications
operating losses. In addition, in the event that additional working capital
becomes necessary to fund communications operations, there can be no assurance
that the Company will be able to obtain financing on terms satisfactory to it.

In August 2002, OnTera, Inc. sold certain access agreements on properties
located in the Los Angeles area and the communications assets located in the
properties for $0.4 million. The transaction resulted in a gain of $0.1 million.
In the quarter ended December 31, 2002, the Company took a $0.7 million charge
for the impairment of certain communications assets in contemplation of exiting
the Internet service business. The Company exited the Internet service

<PAGE>

business in January 2003 and sold the impaired communications assets. In the
quarter ended March 31, 2003, the Company recognized a gain of $112,897 on the
sale of the assets.

On a consolidated basis, the general and administrative expenses increased $0.2
million or 7.7% from $2.6 million in the three months ended March 31, 2002 to
$2.8 million in the three months ended March 31, 2003. The increase in general
and administrative expenses included a $0.2 million increase in payroll and
related costs, a $0.3 million increase in insurance, and a $0.3 million decrease
in rent expense.

As a result of the continuing restructuring of the communications segment, on a
consolidated basis, the general and administrative expenses decreased $0.9
million or 10.5% from $8.6 million in the nine months ended March 31, 2002 to
$7.7 million in the nine months ended March 31, 2003. The decrease in general
and administrative expenses included a $0.4 million decrease in payroll and
related costs, a $0.1 million decrease in telephone expense, a $0.1 million
decrease in bad debt expense, and a $0.3 million decrease in rent expense.

Depreciation and amortization decreased $0.4 million or 66.7% from $0.6 million
in the three months ended March 31, 2002 to $0.2 million in the three months
ended March 31, 2003. The decrease was primarily due to charges of impairment of
communications assets recorded in the previous fiscal year, as well as the sale
of communications assets.

Depreciation and amortization decreased $1.1 million or 61.1% from $1.8 million
in the nine months ended March 31, 2002 to $0.7 million in the nine months ended
March 31, 2003. The decrease was primarily due to charges of impairment of
communications assets recorded in the previous fiscal year, as well as the sale
of communications assets.

Interest income was insignificant in the three months ended March 31, 2003 and
the three months ended March 31, 2002. Interest income was insignificant in the
nine months ended March 31, 2003 compared to $0.2 million in the nine months
ended March 31, 2002. The decrease was due to a decrease in investment of the
Company's excess cash, which was used instead to fund the operating losses of
the communications segment.

Interest expense increased $0.1 million or 25% from $0.4 million in the three
months ended March 31, 2002 to $0.5 million in the three months ended March 31,
2003. Interest expense increased $0.1 million or 7.1% from $1.4 million in the
nine months ended March 31, 2002 to $1.5 million in the nine months ended March
31, 2003. The increase is due to the compounding of the accrued interest on the
Madeleine Loan.

NEW ACCOUNTING STANDARDS ADOPTED

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based
Compensation - Transition and Disclosure - an amendment of FASB Statement No.
123." SFAS No. 148 amends SFAS No. 123, "Accounting for Stock-Based
Compensation," to provide alternative methods of transition for a voluntary
change to the fair value based method of accounting for stock-based employee
compensation. In addition, SFAS No. 148 amends the disclosure requirements of
SFAS No. 123 to require prominent disclosures in both annual and interim
financial statements about the method of accounting for stock-based employee
compensation and the effect of the method used on reported results. The
disclosure requirements apply to all companies for fiscal years ending after
December 15, 2002. The interim disclosure provisions are effective for financial
reports containing financial statements for interim periods beginning after
December 15, 2002. The adoption of SFAS No. 148 is not expected to have a
material impact on the Company's financial statements.

NEW ACCOUNTING STANDARDS NOT YET ADOPTED

In June 2002, the FASB issued SFAS No.146, "Accounting for Costs Associated with
Exit or Disposal Activities." SFAS No. 146 addresses financial accounting and
reporting for costs

<PAGE>

associated with exit or disposal activities and nullified Emerging Issues Task
Force Issue No. 94-3, "Liability Recognition for Certain Employee Termination
Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred
in a Restructuring)." SFAS No. 146 requires that a liability for a cost
associated with an exit or disposal activity be recognized when the liability is
incurred. A fundamental conclusion reached by the FASB in this statement is that
an entity's commitment to a plan, by itself, does not create a present
obligation to others that meets the definition of a liability. SFAS No. 146 also
establishes that fair value is the objective for initial measurement of the
liability. The provisions of this statement are effective for exit or disposal
activities that are initiated after December 31, 2002, with early application
encouraged. The Company has not yet determined the impact of SFAS No.146 on its
financial position and results of operations, if any.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of March 31, 2003, the Company had debt of $16.3 million with a fixed
interest rate of 11.0%. The Company does not have any derivative financial
instruments as of March 31, 2003. The Company believes that the interest rate
risk associated with its investments is not material to the results of
operations of the Company.

ITEM 4 - CONTROLS AND PROCEDURES

(a) Evaluation of disclosure controls and procedures. Based on their evaluation
of the Company's disclosure controls and procedures (as defined in Rules
13a-14(c) and 15-d-14(c) under the Securities Exchange Act of 1934) as of a date
within 90 days of the filing date of this Quarterly Report on Form 10-Q, the
Company's chief executive officer and chief financial officer have concluded
that the Company's disclosure controls and procedures are designed to ensure
that information required to be disclosed by the Company in the reports that it
files or submits under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the SEC's rules and forms and are
operating in an effective manner.

(b) Changes in internal controls. There were no significant changes in the
Company's internal controls or in other factors that could significantly affect
these controls subsequent to the date of their most recent evaluation.
