BROCADE COMMUNICATIONS SYSTEMS, INC.

2013 INDUCEMENT AWARD PLAN

STOCK OPTION AGREEMENT

Unless otherwise defined herein, the terms defined in the 2013 Inducement Award Plan (the “Plan”) shall have the same defined meanings in this Stock Option Agreement (the “Option Agreement”).

Termination Period:

This Option may be exercised for three months after Optionee ceases to be a Service Provider. Upon the death or Disability of the Optionee, this Option may be exercised for one year after Optionee ceases to be a Service Provider. In no event may this Option be exercised later than the Term/Expiration Date as provided above.

A. Grant of Option.

The Administrator hereby grants to the Optionee named in the Notice of Grant attached to this Option Agreement a Nonstatutory Stock Option (the “Option”) to purchase the number of Shares, as set forth in the Notice of Grant, at the exercise price per share set forth in the Notice of Grant (the “Exercise Price”), subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 20(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan will prevail.

B. Exercise of Option.

(a) Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant and the applicable provisions of the Plan and this Option Agreement.

(b) Method of Exercise. This Option is exercisable by delivery of written or electronic notice of exercise, in a form provided by the Administrator (the “Exercise Notice”), which will state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice will be completed by the Optionee and delivered to the Stock Administrator of the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price (together with any applicable tax withholdings) as to all Exercised Shares. This Option will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by such aggregate Exercise Price.

No Shares will be issued pursuant to the exercise of this Option unless such issuance and exercise complies with Applicable Laws. Assuming such compliance, for income tax purposes the Exercised Shares will be considered transferred to the Optionee on the date the Option is exercised with respect to such Exercised Shares.

C. Method of Payment.

Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the election of the Optionee:

(a) cash;

(b) check;

(c) other Shares which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option will be exercised;

(d) net issue exercise, whereby Optionee surrenders an Option at the principal office of the Company (or such other office or agency as the Company may designate) together with a properly completed and executed exercise notice reflecting such election, in which event the Company will issue to the Optionee that number of Shares computed using the following formula:

X = Y (A – B)

      A

Where:

X = the number of Shares to be issued to Optionee;

Y = the number of Shares subject to the Option or, if only a portion of the Option is being exercised, the portion of the Option being cancelled (at the date of such calculation);

A = the Fair Market Value of one Share (at the date of such calculation);

B = the exercise price per Share of the Option (as adjusted to the date of the calculation);

(e) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan; or

(f) any combination of the foregoing methods of payment.

D. Non-Transferability of Option.

This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by the Optionee. Notwithstanding the foregoing, Optionee may, in a manner and in accordance with terms specified by the Administrator, transfer this Option to Optionee’s spouse, former spouse or dependent pursuant to a court-approved domestic relations order which relates to the provision of child support, alimony payments or marital property rights. The terms of the Plan and this Option Agreement will be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.

E. Term of Option.

This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option Agreement.

F. Entire Agreement; Governing Law.

The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This agreement is governed by the internal substantive laws, but not the choice of law rules, of Delaware.

G. NO GUARANTEE OF CONTINUED SERVICE.

OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

By your signature and the signature of the Company’s representative, you and the Company agree that this Option is granted under and governed by the terms and conditions of the Plan and this Option Agreement. Optionee has reviewed the Plan and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option Agreement and fully understands all provisions of the Plan and Option Agreement. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions relating to the Plan and Option Agreement. Optionee further agrees to notify the Company upon any change in the residence address indicated on page one.
