             C-COR.NET CORP. NON-QUALIFIED STOCK OPTION AGREEMENT
             ----------------------------------------------------


          THIS STOCK OPTION AGREEMENT is made and entered into effective as of
the Effective Time by and between the Corporation and ____________, an employee
of Worldbridge (the "Optionee"), a wholly-owned subsidiary of the Corporation.

          Capitalized terms used herein shall have the meaning assigned to such
terms in the attached Appendix.

          WHEREAS, in connection with the Merger Agreement, all options granted
by Worldbridge to acquire Worldbridge common stock that were outstanding
immediately prior to the Effective Time of the Merger were assumed and converted
by the Corporation at the Effective Time into options to acquire Common Stock.
Each Worldbridge option was converted into an option (a "C-COR.net Option") to
acquire .219166 shares (the "Exchange Ratio") of Common Stock, rounded to the
nearest whole share, at an exercise price equal to the exercise price
immediately prior to the Effective Time divided by the Exchange Ratio, rounded
to the nearest cent; and

          WHEREAS, the Corporation desires to (1) provide a mechanism by which
the Corporation can administer the options that were assumed and converted by
the Corporation at the Effective Time in connection with the Merger Agreement;
and (2) promote the interests of the Corporation by providing the persons
holding such options with an opportunity to acquire a proprietary interest in
the Corporation as an incentive for them to remain in the service of
Worldbridge.

          NOW, THEREFORE, in consideration of the mutual covenants hereinafter
set forth and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound hereby, agree as follows:

          1    Assumption and Conversion of Option.  The Optionee's option to
               -----------------------------------
purchase Worldbridge common stock was assumed and converted at the Effective
Time pursuant to the terms of the Certificate of Assumption between the
Corporation and Optionee attached hereto as Exhibit A.

          2    Timing of Exercise.  All C-COR.net Options are fully vested and
               ------------------
fully exercisable as of the Effective Time, and, as stated in the Certificate of
Assumption, will expire with respect to any then unexercised portion on July 1,
2007 (ten (10) years from the date on which the original Worldbridge option was
granted).

          3    Manner of Exercise.  This C-COR.net Option shall be exercised by
               ------------------
the Optionee (or other party entitled to exercise the C-COR.net Option under
Section 4 or Section 5
---------    ---------
<PAGE>

of this Agreement) by delivering written notice to the Corporation stating the
number of shares of Common Stock to be purchased, the person or persons in whose
name the shares are to be registered and each such person's address and social
security number. Such notice shall not be effective unless accompanied by the
full purchase price for all shares so purchased. The purchase price shall be
payable in cash (payment in currency or by certified check, cashier's check,
postal money order or wire transfer shall be considered payment in cash), in the
form of shares of Common Stock already owned by Optionee or shares subject to
the C-COR.net Option. In the event of payment in the Corporation's Common Stock,
the shares used in payment of the purchase price shall be considered payment to
the extent of their Fair Market Value on the date of exercise of this C-COR.net
Option. The Corporation shall have the right to require the Optionee to remit to
the Corporation an amount of cash sufficient to satisfy any federal state and
local withholding tax requirements prior to the delivery of any certificate for
such shares.

          4    Nontransferability of Option.  This C-COR.net Option shall not be
               ----------------------------
transferable by the Optionee otherwise than by will or by the laws of descent
and distribution, and is exercisable during Optionee's lifetime only by the
Optionee.  The terms of this C-COR.net Option shall be binding on the executors,
administrators, heirs and successors of the Optionee.

          5    Corporate Transaction.
               ---------------------

               5.1   In the event of any Corporate Transaction, each outstanding
C-COR.net Option shall be (i) assumed by the successor corporation (or parent
thereof) or (ii) replaced with a comparable option to purchase shares of the
capital stock of the successor corporation (or parent thereof) at the time of
the Corporate Transaction which provides for subsequent payout in accordance
with the same schedule applicable to such C-COR.net Option. The determination of
option comparability under clause (ii) above shall be made by the Board, and its
determination shall be final, binding and conclusive.

               5.2   Unless otherwise provided by the Board, immediately
following the consummation of a Corporate Transaction, all outstanding C-COR.net
Options shall terminate and cease to be outstanding, except to the extent
assumed by the successor corporation (or parent thereof).

               5.3   Each C-COR.net Option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee upon consummation of such Corporate
Transaction, had the C-COR.net Option been exercised immediately prior to such
Corporate Transaction.  Appropriate adjustments shall also be made to (i) the
number and class of securities available for issuance under this Stock Option
Agreement following the consummation of such Corporate Transaction and (ii) the
exercise price payable per share under each outstanding C-COR.net Option,
provided the aggregate exercise price payable for such securities shall remain
--------
the same.
