                                DELTATHREE, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.    BASIS OF PRESENTATION

      The unaudited condensed consolidated financial statements of deltathree,
Inc. and its subsidiaries (collectively referred to in this report as the
"Company", "we", "us", or "our"), of which these notes are a part, have been
prepared in accordance with generally accepted accounting principles for interim
financial information and pursuant to the instructions of Form 10-Q and Article
10 of Regulation S-X. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for annual
financial statements. In the opinion of our management, all adjustments
(consisting only of normal recurring accruals) considered necessary for a fair
presentation of the financial information as of and for the periods presented
have been included.

      The results for the interim periods presented are not necessarily
indicative of the results that may be expected for any future period. The
unaudited condensed consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes for the
year ended December 31, 2004 included in our Annual Report on Form 10-K.


2.    NET LOSS PER SHARE

      The shares issuable upon the exercise of stock options and warrants are
excluded from the calculation of net loss per share, as their effect would be
antidilutive.


3.    STOCK-BASED COMPENSATION

      We follow accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" and Financial Accounting Standards Board (FASB)
Interpretation No. 44 for our stock-based compensation plans. Pursuant to these
accounting pronouncements, we do not recognize expense for stock options granted
to employees if the exercise price is at least equal to the market value of the
underlying stock at the date of grant. Deferred compensation is amortized to
compensation expense over the vesting period of the options.

      In accordance with Statement of Financial Accounting Standards (SFAS) No.
123, "Accounting for Stock-Based Compensation", as amended by SFAS No. 148, if
we had elected to recognize compensation expense for the issuance of options to
our employees based on the fair value method of accounting prescribed by SFAS
No. 123, net income (loss) and earnings (loss) per share would have been reduced
to the pro forma amounts as follows (in thousands, except per share amounts):

      For the purpose of presenting pro forma information required under SFAS
123, the fair value option grant has been estimated on the date of grant using
the Black-Scholes option pricing model for grants made after the Company became
a public entity.

      During the nine and three months ended September 30, 2005 there were new
option grants. The following assumptions were used for the nine and three months
periods ended September 30, 2005: dividend yield of 0.00% for all periods;
risk-free interest rate of 4.06% for all periods, an expected life of 3-years
for all periods; a volatility rate of 78% for all periods

Consolidated Financial Statements and the Notes thereto included in our Annual
Report on Form 10-K for the year ended December 31, 2004.

FORWARD-LOOKING STATEMENTS

      This Management's Discussion and Analysis of Financial Condition and
Results of Operation (MD&A) contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended. These forward-looking
statements are based on current expectations, estimates, forecasts and
projections about us, our future performance, the industries in which we

materially from what is expressed or forecasted in such forward-looking
statements. These risks and uncertainties include, but are not limited to, the
following: uncertainty of financial estimates and projections, the competitive
environment of Internet telephony and our ability to compete effectively, our
limited operating history, changes in the rates of all related
telecommunications services, the level and rate of customer acceptance of new
products and services, governmental regulation and legal uncertainties that may
affect the Internet telephony industry, and rapid changes in technology, as well
as other risks referenced from time to time in our filings with the Securities
and Exchange Commission (SEC). For a more complete list and description of such
risks and uncertainties, refer to our Form 10-K for the year ended December 31,
2004. Except as required under the federal securities laws and the rules and

million for the nine months ended September 30, 2005 from approximately $5.4
million for the nine months ended September 30, 2004 due primarily to a reduced

(including sales of our Hosted Communications Solution) increased approximately
$6.3 million or 68.4% to approximately $15.5 million for the nine months ended
September 30, 2005 from approximately $9.2 million for the nine months ended

COSTS AND OPERATING EXPENSES

      COST OF REVENUES. Cost of revenues increased by approximately $3.2 million
or 33% to approximately $12.9 million for the nine months ended September 30,

increased by approximately $0.6 million or 33% to approximately $2.4 million for
the nine months ended September 30, 2005 from approximately $1.8 million for the
nine months ended September 30, 2004, due to higher personnel costs associated
with the development of new services and enhancements to our existing services.

      SELLING AND MARKETING EXPENSES. Selling and marketing expenses increased
by approximately $0.5 million or 20.8% to approximately $2.9 million for the
nine months ended September 30, 2005 from approximately $2.4 million for the
nine months ended September 30, 2004 due to slightly higher personnel and
external marketing related costs associated with the sales and marketing of our
products and services.

increased by approximately $0.5 million or 31.25% to approximately $2.1 million
for the nine months ended September 30, 2005 from approximately $1.6 million for

approximately $0.6 million or 28.6% to approximately $1.5 million for the nine
months ended September 30, 2005 from approximately $2.1 million for the nine
months ended September 30, 2004 primarily due to a lower level of certain assets
purchased in prior years being included in the computation of depreciation
expense in 2005 compared to 2004 as they have already been fully depreciated in
prior periods.

LOSS FROM OPERATIONS

      Loss from operations decreased by approximately $1.7 million or 60.7% to
approximately $1.1 million for the nine months ended September 30, 2005 from

increased by approximately $0.1 million or 14.3% to approximately $0.8 million
for the three months ended September 30, 2005 from approximately $0.7 million
for the three months ended September 30, 2004, due to higher personnel costs
associated with the development of new services and enhancements to our existing
services.

      SELLING AND MARKETING EXPENSES. Selling and marketing expenses increased
by approximately $0.3 million or 42.8% to approximately $1 million for the three

approximately $0.2 million for the three months ended September 30, 2005 from

$40,000 for the three months ended September 30, 2005 from approximately $0.7
million for the three months ended September 30, 2004 due to the foregoing
factors.


LIQUIDITY AND CAPITAL RESOURCES

      Since our inception in March 1996, we have incurred significant operating
and net losses, due in large part to the start-up and development of our
operations. As of September 30, 2005, we had an accumulated deficit of
approximately $152 million.

      As of September 30, 2005, we had cash and cash equivalents of
approximately $4.8 million, marketable securities and other short-term
investments of approximately $0.5 million, long-term investments of $10 million
and working capital of approximately $1.2 million. We generated negative cash
flow from operating activities of approximately $0.5 million during the nine
months ended September 30, 2005 compared with positive cash flow from operating
activities of approximately $0.1 million during the nine months ended September
30, 2004. Accounts receivable were approximately $0.8 million and $0.3 million
at September 30, 2005 and September 30, 2004, respectively.

      Our capital expenditures were approximately $1.0 million expended in the
nine months ended September 30, 2005 compared to approximately $1.1 million
expended in the nine months ended September 30, 2004 as we continued to both
make moderate investments and optimize our overall utilization of our existing
domestic and international network infrastructure.


                                        9



      Short-term, we obtain our funding from our utilization of the remaining
proceeds from our initial public offering offset by positive or negative cash
flow from our operations. These proceeds are maintained as cash, cash
equivalents, and short-term investments with an original maturity of twelve
months or less. Based on current trends in our operations, we believe that these
funds will be sufficient to meet our working capital requirements, including
operating losses, and capital expenditure requirements for at least the next
fiscal year, assuming that our business plan is implemented successfully, and
that:

      o     our recent revenue trends, which reflected an increase in our
            higher-margin (primarily PC-to-Phone and Broadband Phone) products
            and services, continue to increase;

      o     our indirect expense trends remain at or near the rates of our third
            quarter 2005 rates, which were moderately increased compared to the
            past twelve months as we make moderate increases in personnel to
            support increased revenue generation activities and through the
            continued curtailment of discretionary expenditures, and reduced
            network rent and termination rates from our carriers; and

      o     our net cash-burn rate, which was reduced during the past twelve
            months due to the foregoing factors, and eliminated for the first
            quarter of 2005, continues to improve throughout the remainder of
            2005 and beyond.

      To the extent that these trends do not remain steady, or if in the
longer-term we are not able to successfully implement our business strategy, we
may be required to raise additional funds for our ongoing operations. Additional
financing may not be available when needed or, if available, such financing may
not be on terms favorable to us. If additional funds are raised through the
issuance of equity securities, our existing stockholders may experience
significant dilution. In addition, we cannot assure you that any third party
will be willing or able to provide additional capital to us on favorable terms
or at all.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The SEC's rule related to market risk disclosure requires that we describe
and quantify our potential losses from market risk sensitive instruments
attributable to reasonably possible market changes. Market risk sensitive
instruments include all financial or commodity instruments and other financial
instruments (such as investments and debt) that are sensitive to future changes
in interest rates, currency exchange rates, commodity prices or other market
factors. We believe that our exposure to market risk is immaterial. We currently
do not invest in, or otherwise hold, for trading or other purposes, any
financial instruments subject to market risk.


                                       10



ITEM 4. CONTROLS AND PROCEDURES

      (a) Evaluation of Disclosure Controls and Procedures.

      Our principal executive officer (CEO) and principal financial officer
(CFO), with the participation of our management, evaluated the effectiveness of
our disclosure controls and procedures. Based on that evaluation, the CEO and
CFO have concluded that as of the end of the period covered by this report, our
disclosure controls and procedures are effective to provide reasonable assurance
that information required to be disclosed by us in reports that we file or
submit under the Securities and Exchange Act of 1934, as amended, is recorded,
processed, summarized and timely reported as provided in the SEC rules and
forms.

      (b) Changes in Internal Controls.

      There have been no changes in our internal control over financial
reporting that occurred during the quarter ended September 30, 2005 that have
materially affected, or are reasonably likely to materially affect, our internal
control over financial reporting.


                                  11



                                PART II
                           OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

      We, as well as certain of our former officers and directors, were named as
defendants in a number of purported securities class actions in United States
District Court for the Southern District of New York, arising out of our initial
public offering in November 1999 (the "IPO"). On August 31, 2005, the Court
granted preliminary approval of an omnibus settlement of the litigation. Under
the terms of the proposed settlement agreement, we are not conceding any
liability and we presently do not expect to make any payments under the pending
settlement, other than legal fees we may incur.


      We are not a party to any other material litigation and are not aware of
any other pending or threatened litigation that could have a material adverse
effect on us or our business taken as a whole.
