Item 7.  Exhibits

         (c)      Exhibits

         Exhibit 99.1    Press Release of Pinnacor Inc. dated October 23, 2003
                         reporting financial results for the third quarter
                         of 2003


Item 12.  Disclosure of Results of Operations and Financial Condition

On October 23, 2003 the Registrant will announce its financial results for the
third quarter of 2003 in a presentation broadly accessible to the public by
dial-in conference call and via webcast.

The following information, including the exhibit attached hereto, shall not be
deemed "filed" for purposes of Section 18 of the Securities Act of 1934, nor
shall it be deemed incorporated by reference in any filing under the
Securities Act of 1933, except as shall be expressly set forth by specific
reference in such filing.

In addition to financial results determined in accordance with generally
accepted accounting principles ("GAAP"), Pinnacor utilizes non-GAAP financial
measures (within the meaning of Regulation G promulgated by the Securities and
Exchange Commission) in its third quarter 2003 press release and conference
call. For purposes of Regulation G, a non-GAAP financial measure is a
numerical measure of a registrant's historical or future financial
performance, financial position or cash flows that excludes amounts, or is
subject to adjustments that have the effect of excluding amounts, that are
included in the most directly comparable measure calculated and presented in
accordance with GAAP in the statement of income, balance sheet or statement of
cash flows (or equivalent statements) of the issuer; or includes amounts, or
is subject to adjustments that have the effect of including amounts, that are
excluded from the most directly comparable measure so calculated and
presented. These measures should be considered in addition to results prepared
in accordance with GAAP, but are not a substitute for or superior to GAAP
results. Non-GAAP financial measures are used because management believes this
information provides investors useful information in evaluating the results of
the continuing operations and believes that this information provides the
users of the financial statements a valuable insight into the operating
results of Pinnacor. The non-GAAP measure of adjusted EBITDA is presented to
supplement the consolidated financial statements in accordance with GAAP.
Pinnacor defines adjusted EBITDA as operating loss excluding depreciation and
amortization, restructuring and asset abandonment charges, stock-based
compensation and transaction related charges. Specifically, management
believes that adjusted EBITDA is of interest to its investors because Pinnacor
excludes these costs when analyzing operations. Adjusted EBITDA does not
represent cash flow from operations, as defined by GAAP. Adjusted EBITDA
should not be considered a substitute for net income or loss, or as an
indicator of operating performance or whether cash flows will be sufficient to
fund cash needs.

Attached and incorporated herein by reference as Exhibit 99.1 is a copy of a
press release of the Registrant, dated October 23, 2003, reporting the
Registrant's financial results for the third quarter of 2003.
