                     NOTES TO UNAUDITED FINANCIAL STATEMENTS

                                  JUNE 30, 2001

1.       BASIS OF PRESENTATION

         The financial statements have been prepared by the Company, without
         audit, pursuant to the rules and regulations of the Securities and
         Exchange Commission and reflect all adjustments which are, in the
         opinion of management, necessary to present fairly the information
         required herein. Certain information and footnote disclosures normally
         included in the financial statements prepared in accordance with
         generally accepted accounting principles have been omitted pursuant to
         such rules and regulations, although management believes that the
         disclosures are adequate to make the information presented not
         misleading. The results of operations for the six-month periods ended
         June 30, 2001 and 2000 are not necessarily indicative of the results of
         operations to be expected for the full year.

         These statements should be read in conjunction with the financial
         statements of Voicenet, Inc. and notes thereto included in the
         Company's Annual Report on Form 10-KSB for the year ended December 31,
         2000 and Form 8-K dated June 5, 2001.

2.       NATURE OF BUSINESS

         Voicenet, Inc. (the "Company"), a Delaware corporation, was
         incorporated on April 2, 1996. The Company was established for the
         marketing and distribution of continuous speech and voice recognition
         systems. The Company has had minimal sales and, has incurred losses
         since inception. The Company is currently in the developmental stage
         and has no significant operations to date. The Company is majority
         owned by Voicenet (Aust.) Ltd. ("VNA") an Australian company.

3.       NET LOSS PER COMMON SHARE

         Net loss per common share is computed based on the weighted average
         number of shares of common stock outstanding for the periods presented.
         The effect of stock options and warrants on the net loss per share was
         anti-dilutive for the periods presented.

4.       PURCHASE OF TECHNOLOGY

         On August 1, 1996, the Company entered into a Technology and Sales
         Agreement (the "technology agreement") with VNA to acquire certain
         exclusive rights and ownership with respect to the development, use,
         marketing, sales and distribution of a continuous computer based
         digital voice compression, recognition and recording technology. The
         term of the agreement is for the longer of 25 years or the life of any
         patents and extensions granted under the patent applications.

MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION:

The Company had no revenues from continuing operations through the six months
ended June 30, 2001. The Company has incurred losses since its inception in
1996. The Company's losses incurred since inception have resulted principally
from professional, marketing and travel expenditures incurred in connection with
its capital raising activities and from amortization of intangibles and
stock-based compensation. The Company expects to incur operating costs and
possible losses there from over the next several years due primarily to costs
associated with seeking potential acquisition candidates and to expanded sales
and marketing efforts, including the establishment of product sales office, the
staffing of such office and other marketing activities and costs to be incurred
as they seek potential customers for the Company's products.

There can be no assurance of when and whether the Company will generate revenue
or become profitable on a sustained basis, if at all. The timing of revenues, if
any, may not match the timing of associated product development and other
expenses.

RESULTS OF OPERATIONS FOR THE SIX-MONTH PERIOD ENDED JUNE 30, 2001; AS COMPARED
WITH JUNE 30, 2000

Net loss for the six-month period ended June 30, 2001 was $1,731,670 as compared
to $482,362 for the six-month period ended June 30, 2000. There were no revenues
for the six-month period ended June 30, 2001 or for the six-month period ended
June 30, 2000. Total selling and administrative expenses were $948,414 for 2001
as compared to $195,233 for the six-month period ended June 30, 2000. This
increase was primarily attributable to approximately $315,000 of costs incurred
in connection with a planned merger with ESS Communications, Inc. that was
terminated. Additionally, the Company has increased travel and conference
expenses of approximately $200,000. These expenses are associated with the
Company's ongoing attempts to acquire an operating company in connection with
its overall business plan.

As previously reported, the Company's former chief executive officer Mr. Alan
Dawson resigned in June 2001. The total severance expense for the six-month
period ended June 30, 2001 was $173,000, which consisted of a one-time payment
of $98,000 and an agreement to waive repayment of approximately $75,000 of
advances made to Mr. Dawson.

LIQUIDITY AND CAPITAL RESOURCES

The Company had working capital of $2,212,836 on December 31, 2000, in
comparison to working capital of $929,632 on June 30, 2001. The decrease in
working capital was primarily due to the advances of funds in anticipation of a
proposed merger and selling and administrative expenses, including costs
incurred in connection with the proposed merger. The Company has terminated any
negotiations in connection with the merger. The increase in the accumulated
deficit is primarily related to continuing operating costs with minimal
operating and / or investment income. In addition, the Company recognized
$219,325 of equity in the loss of Unveil Technologies, Inc. (an unconsolidated
affiliate) during the six-month period ended June 30, 2001. For the six-month
period ended June 30, 2001, the Company's cash requirements were satisfied from
the cash reserves in its operating accounts.

                                        7

In the course of its development activities the Company has sustained continuing
losses and expects such losses to continue for at least the foreseeable future.
The Company's management plans on conserving and advancing funds on an as needed
basis. In the longer term, the Company will be dependant upon revenues from the
operations of its existing and/or other business opportunities. The Company's
ability to continue as a going concern is dependent on these additional
management advances, and, ultimately, upon achieving profitable operations.
