STOCK OPTION ASSUMPTION AGREEMENT

Dear [Field: Full Name]:

As you know, on November 14, 2011 (the "Closing Date") Cisco Systems, Inc. ("Cisco") acquired Beaumaris Networks, Inc. (d/b/a BNI) ("BNI") (the "Acquisition") pursuant to the Agreement and Plan of Merger by and among Cisco Sytems, Inc., Boost Acquisition Corp., Beaumaris Networks, Inc. and the Stockholders153 Agent dated as of October 19, 2011. On the Closing Date you held one or more outstanding options to purchase shares of common stock granted to you under the Beaumaris Networks, Inc. 2009 Stock Plan (the "Plan"). Pursuant to the Merger Agreement, on the Closing Date, Cisco assumed all obligations of BNI under your outstanding option (or options). This Stock Option Assumption Agreement (the "Agreement") evidences the terms of Cisco153s assumption of an option (or options) to purchase BNI common stock granted to you under the Plan (the "BNI Option(s)"), and documented by a stock option agreement (or stock option agreements) and any amendment(s) and/or option assumption agreements entered into by and between you and BNI (the "Option Agreement(s)"), including the necessary adjustments for assumption of the BNI Option(s) that are required by the Acquisition.

The table below summarizes your BNI Option(s) immediately before and after the Acquisition:

Grant Details

The post-Acquisition adjustments are based on the Option Exchange Ratio of 0.3067180780 as determined in accordance with the terms of the Merger Agreement, and are intended to: (i) assure that the total spread of your assumed BNI Option(s) (i.e., the difference between the aggregate fair market value and the aggregate exercise price) does not exceed the total spread that existed immediately prior to the Acquisition; and (ii) to preserve, on a per share basis, the ratio of exercise price to fair market value that existed immediately prior to the Acquisition. The number of shares of Cisco common stock subject to your assumed BNI Option(s) was determined by multiplying the Option Exchange Ratio by the number of shares remaining subject to your BNI Option(s) on the Closing Date and rounding the resulting product down to the next whole number of shares of Cisco common stock. The exercise price per share of your assumed BNI Option(s) was determined by dividing the exercise price per share of your BNI Option(s) by the Option Exchange Ratio and rounding the resulting quotient up to the next whole cent.

Unless the context otherwise requires, any references in the Plan or the Option Agreement(s) to: (i) the "Company" or the "Corporation" means Cisco, (ii) "Stock," "Common Stock" or "Shares" means shares of Cisco common stock, (iii) the "Board of Directors" or the "Board" means the Board of Directors of Cisco and (iv) the "Committee" means the Compensation and Management Development Committee of the Board of Directors of Cisco. All references in the Option Agreement(s) and the Plan relating to your status as an employee or consultant of BNI will now refer to your status as an employee or consultant of Cisco or any present or future Cisco subsidiary.

The vesting commencement date, vesting schedule and expiration date of your assumed BNI Option(s) remain the same as set forth in the Option Agreement(s) (in this respect, please note that any discussion of option terms (including vesting acceleration) in any employment offer letter (whether from Cisco, BNI or any other related employer) is explanatory in nature and will not result in duplication of benefits (including vesting) with respect to your assumed BNI Option(s)) but with the number of shares subject to each vesting installment and the exercise price per share adjusted to reflect the effect of the Acquisition. Vesting of your assumed BNI Option(s) will be suspended during all leaves of absence in accordance with Cisco153s policies and, the only permissible methods to exercise your assumed BNI Option(s) are cash, check, wire transfer, or through a cashless exercise program with a Cisco-designated broker. All other provisions which govern either the exercise or the termination of your assumed BNI Option(s) remain the same as set forth in the Option Agreement(s), and the provisions of the Option Agreement(s) will govern and control your rights under this Agreement to purchase shares of Cisco common stock, except (i) no assumed BNI Option(s) may be "early exercised" (i.e., an assumed BNI Option(s) may be exercised for shares of Cisco common stock only to the extent vested at the time of exercise pursuant to the applicable vesting schedule) and (ii) as expressly modified by this Agreement, the Merger Agreement or otherwise in connection with the Acquisition. Upon termination of your employment with Cisco or any present or future Cisco subsidiary, you will have the

applicable limited post-termination exercise period specified in your Option Agreement(s) for your assumed BNI Option(s) to the extent vested and outstanding at the time of termination after which time your assumed BNI Option(s) will expire and NOT be exercisable for Cisco common stock.

To exercise your assumed BNI Option(s), you must utilize one of Cisco153s preferred brokers, the Charles Schwab Corporation (telephone number is ) or Morgan Stanley Smith Barney (telephone number is ).

Nothing in this Agreement or the Option Agreement(s) interferes in any way with your right and your employer153s right, which rights are expressly reserved, to terminate your employment at any time for any reason. Future options, if any, you may receive from Cisco will be governed by the terms of the Cisco stock option plan under which such options are granted, and such terms may be different from the terms of your assumed BNI Option(s), including, but not limited to, the time period in which you have to exercise vested options after your termination of employment.

Until Cisco153s Stock Administration Department is in receipt of your understanding and acceptance of this Agreement (which can be accomplished electronically by following the instructions under the heading of Acknowledgment below) your Cisco account will not be activated and your assumed BNI Option(s) will not be exercisable.
