                          NOTES TO UNAUDITED PRO FORMA
                            STATEMENTS OF OPERATIONS

    On June 9, 1999, the Company acquired all of the outstanding capital stock
of Convoy Corporation, a Delaware corporation ("Convoy"), by means of the
statutory merger of a wholly owned subsidiary with and into Convoy. Convoy is a
worldwide provider of application integration software for PeopleSoft
applications.

    The aggregate consideration paid by the Company was $42,809,000. At closing,
the Company issued 807,115 unregistered shares of its common stock valued at
$36,267,000. The Company also issued 105,333 stock options exercisable for
shares of the Company's common stock to assume all outstanding Convoy stock
options and warrants valued at approximately $4,733,000. Fees and expenses
related to the acquisition were approximately $1,809,000. The acquisition was
accounted for under the purchase method of accounting and, accordingly, the
assets, liabilities and operating results of Convoy have been included in the
accompanying consolidated financial statements from June 1, 1999.

    An independent valuation of Convoy's net assets was performed to assist in
the allocation of the purchase price. A portion of the purchase price was
assigned to marketable software products ($8,500,000) and goodwill
($35,903,000), which are being amortized on a straight-line basis over three and
seven-year periods, respectively. Convoy's other assets were valued at
approximately $2,129,000 and its liabilities assumed totaled approximately
$3,723,000.

    In August 1999, the Company agreed with the former stockholders of Convoy to
provide additional consideration to more closely reflect the value agreed upon
in the original purchase negotiations. Accordingly, 618,225 shares of the
Company's common stock will be issued to the prior Convoy stockholders subject
to final documentation and approval by the parties. As of the date of this
report, the Company has received approval of the agreement from a number of the
former Convoy stockholders. This adjustment to the purchase consideration will
be reflected in the Company's financial statements for the third quarter of 1999
as a one-time charge to net income of approximately $8,500,000 and has not been
reflected in the accompanying pro forma statements.

    The NEON and Convoy statements of operations have been combined for the year
ended December 31, 1998 and the six-month period ended June 30, 1999 for the
presentation of unaudited pro forma statements of operations only. For pro forma
purposes, the historical statements of operations of NEON and Convoy have been
combined as if the acquisition had occurred as of the beginning of the earliest
period presented (January 1, 1998). These unaudited pro forma statements of
operations, including the notes thereto, should be read in conjunction with the
historical consolidated financial statements of NEON and Convoy for the
indicated periods. Certain reclassifications to the Convoy historical financial
statements have been made to conform to the NEON presentation.

    NOTE 1. The Convoy acquisition was effective for accounting purposes as of
June 1, 1999, and, accordingly, Convoy's June 1999 results of operations have
been consolidated in NEON's historical Statement of Operations for the six
months ended June 30, 1999.

    NOTE 2. The unaudited pro forma net loss per share is based on the actual
weighted average number of shares of NEON common stock outstanding during the
period, adjusted to give effect to 807,115 shares of the Company's common stock
issued pursuant to this acquisition as if they were outstanding from January 1,
1998.

    NOTE 3. Reflects the agreement to provide additional consideration to the
former stockholders of Convoy valued at $8,500,000 as discussed above.

    NOTE 4. Pro forma adjustments related to the Convoy purchase price
allocation reflects the amortization of intangibles associated with the purchase
of Convoy as if the acquisition was completed as of January 1, 1998.
