Mr. Robert Annunziata
95 Minisink Road
Short Hills, NJ 07078

Dear Bob:

         This letter ("Letter Agreement") will confirm the terms of your
employment with Velocita Corporation (the "Company"), where you will serve as
the Executive Chairman of the Board of Directors of the Company (the "Board").
Your employment will commence on October 1, 2001 (the "Commencement Date") and
will continue until December 31, 2002 (the "Employment Term"), unless the
Company and you agree to extend the Employment Term until December 31, 2003.

         DUTIES.

         Except as otherwise provided below, you will devote your full business
time to the performance of your duties as Executive Chairman and, you agree to
use your best efforts in the performance of such duties. Your primary duties
will include, leading, with Kirby G. Pickle, Jr., the Company's (i) mergers and
acquisitions efforts, (ii) strategic financing efforts, (iii) capital
conservation efforts, (iv) strategic network development efforts, (v) strategic
sales efforts and (vi) any other area of the Company's business or duties that a
majority of the Board determines warrants your attention, provided such area or
duties are consistent with your position. You will not accept any other full or
part-time position of any kind, and you agree to limit your outside board
directorships to three (3), and you further agree that you will not be the
Chairman of any other company or accept any board position with a competitive
entity without the prior written consent of the Board. Notwithstanding the
foregoing, you may (a) devote a portion of your time to the Atlantic Enterprise
Fund, Inc. and its affiliates and (b) you may manage your personal and family
passive investments, provided the activities in (a) and (b) in the aggregate do
not materially interfere or conflict with the performance of your duties
hereunder.

         COMPENSATION.

         During the Employment Term, the Company will pay you a base salary at
the rate of

<Page>

$500,000 per year, subject to the next sentence, in accordance with the usual
payroll practices of the Company. If the Employment Term is extended, your base
salary will be reviewed by the Board for increase, but may not be decreased. For
calendar year 2002 (and, for calendar year 2003, if the Employment Term is
extended), you will receive a minimum annual performance bonus in the amount of
$500,000 payable when annual bonuses are normally paid to other executives of
the Company, provided that you are employed by the Company at the end of the
applicable calendar year (the "Annual Bonus"). If the Employment Term is
extended, your minimum Annual Bonus will be reviewed by the Board and, you may
be awarded an additional bonus, as determined by the Board in its sole
discretion.

         You acknowledge receipt of $1,250,000 which is a portion of the sign-on
bonus referenced in Section 5 of the Term Sheet entered into between you and the
Company, dated October 9, 2001 and, the Company agrees to pay you an additional
$1,250,000 on January 1, 2002, provided you are employed by the Company on such
date or are terminated prior thereto without Cause (as defined below) or you
voluntarily resign for Good Reason (as defined below). If prior to December 31,
2002, you cease to be employed by the Company for any reason other than your
death, your termination without Cause or your voluntary resignation for Good
Reason, you agree to repay (on a full-recourse basis) to the Company an amount
equal to $2,500,000 multiplied by a fraction, the numerator of which is the
number of days remaining in the period commencing on the Commencement Date and
ending on December 31, 2002 after your termination of employment and, the
denominator of which is 457, within fifteen (15) days of your termination of
employment.

         You will be eligible to receive a merger transaction bonus payable in
accordance with the provisions of this paragraph. You will receive $3,000,000
(the "Transaction Bonus") upon the closing of (i) a merger or consolidation of
the Company with any other corporation or (ii) an agreement for the sale or
disposition by the Company of all or substantially all of the Company's assets
(or any transaction having a similar effect) ((i) and/or (ii) referred to as a
"Transaction"), provided that a majority of the Board (with you entitled to vote
as a Board member if you are then on the Board) determines in good faith (which
determination shall not be unreasonably withheld) that such Transaction is
likely to (x) assure the financial viability of the Company for the next twenty
four (24) months following the applicable Transaction and (y) provide each
shareholder with value in the Company after the Transaction that is not less
than each shareholder's (and its affiliates) investment (including debt) in the
Company. In the event (x) above is satisfied but, not (y), as soon as
practicable after the parties hereto know the material terms of such
Transaction, you and the Board shall discuss, in good faith, what, if any
portion of the Transaction Bonus you will receive in consideration of your
efforts regarding the resulting Transaction. Notwithstanding the foregoing, you
will only receive the Transaction Bonus if you are employed by the Company at
the time of execution of the contract for the applicable Transaction, such
Transaction closes and, you fulfill your obligations hereunder through the end
of the Employment Term or you incurred within one (1) year prior to the
execution of such contract, a termination of employment by the Company without
Cause, you voluntarily resigned for Good Reason or your employment was
terminated on December 31, 2002 as a result of non-renewal of the Employment
Term by the Company (i.e., while you were willing to continue to work on the
same basis as set forth herein (other than your right to the sign-on bonus any
other provision not applicable by its terms)) and the Transaction thereafter
closes. You are only


                                       2
<Page>

eligible to receive one Transaction Bonus hereunder, regardless of the number of
transactions that occur or how long this Letter Agreement is effective.
Notwithstanding the execution of any contract, the Transaction Bonus shall not
be paid to you unless and until the closing of a Transaction.

         You will be eligible to receive a bonus in connection with Major Asset
Sales (as defined below) for contracts both entered into and closed after the
Commencement Date while you are employed by the Company. You will receive an
amount equal to one percent (1%) of the Net Sales (as defined below) (the "Asset
Sale Bonus") provided each transaction or series of related transactions result
in Net Sales greater than $2,500,000. The Asset Sale Bonus will be paid to you
as and when cash proceeds are received from the buyer and are subject to all
adjustments or settlements with the buyer. In addition, you will receive an
amount equal to one percent (1%) of strategic cash invested in the Company for
equity capital while you are employed other than from current investors and debt
holders and their affiliates (the "Equity Bonus"). The Equity Bonus will be paid
to you as and when the proceeds are received from the investors.

         The Board, in its sole discretion, will make the determination of
whether or not to enter into, or close, any sales or investment transactions(s)
pursuant to the above paragraph or any Transaction, and, therefore, you agree
and acknowledge that you have no claim or rights of any kind whatsoever as a
result of the Board's decision not to enter into, or close, any Transaction(s),
sale or investment transaction(s) or to pursue any claim for payment or to
settle any claim.

         While you are employed by the Company, you will be entitled to
participate, to the extent eligible thereunder, in all employee benefit plans
and programs, in accordance with the terms thereof in effect from time to time,
as are provided by the Company to senior management of the Company.

         TERMINATION.

         Your service as Executive Chairman, unless extended by the mutual
written agreement of you and the Company, will terminate at the end of the
Employment Term or, if earlier, on the earliest to occur of your death,
termination by the Company for Disability, termination by the Company with or
without Cause or your voluntary termination with or without Good Reason. In the
event of a non-renewal of the Employment Term by either party, the Company will
only be obligated to pay you the amounts described in (i) through (iii) below,
and as provided with regard to a Transaction Bonus above, and in no event shall
such non-extension be deemed a termination without Cause or a voluntary
resignation for Good Reason.

         In the event your employment with the Company is terminated during the
Employment Term by you or by the Company for any reason the Company will pay you
(i) any earned but unpaid base salary through the date of termination, (ii) any
unreimbursed business expenses otherwise reimbursable in accordance with the
Company's policies, (iii) benefits in accordance with the terms of the
applicable plans and programs of the Company and (iv) if your employment is
terminated by the Company without Cause or by you for Good Reason (but not a
non-renewal of the Employment Term) and, subject to your execution of a release
of all claims against the Company in such form as reasonably requested by the
Company, your base salary through the


                                       3
<Page>

remainder of the Employment Term or, twelve (12) months, if greater and the
guaranteed Annual Bonus for the year of termination. Upon such payments the
Company shall have no further obligations under this Agreement, except as
provided with regard to the Transaction Bonus.

specifying the failure and, that it will be treated as Cause if you fail to
promptly perform such duties; or (iii) your conviction of, or pleading of NOLO
CONTENDERE to, a felony. For these purposes (other than subsection (ii) above),

is given and the right to cure any breach within fifteen (15) days.
