I am the holder of a stock appreciation right (“SAR”) granted to me under the Casa Systems, Inc. (the “Company”) 2011 Stock Incentive Plan on 2 (the “Grant Date”) measured by the appreciation from and after the Grant Date in the Fair Market Value of 3 shares of Common Stock of the Company.

No Right to Continued Service or Awards. Nothing in the adoption of the Plan, nor the award of the DSUs thereunder pursuant to the Grant Notice and this Agreement, shall confer upon the Participant the right to a continued service relationship with the Company or any Affiliate, or any other entity, or affect in any way the right of the Company or any such Affiliate, or any other entity to terminate such service relationship at any time. The grant of the DSUs is a one-time benefit and does not create any contractual or other right to receive a grant of deferred stock units or other Awards or any payment or benefits in the future. Any future Awards will be granted at the sole discretion of the Board or the Committee acting on behalf of the Company.

Right to Grant Security Interest; No Further Encumbrances. The Grantors have the right to grant a security interest in the Collateral.

For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

Nothing herein or in the Grant Notice or in the Plan confers any right or obligation on you to continue in the employ of the Company or any subsidiary or shall affect in any way your right or the right of the Company or any subsidiary, as the case may be, to terminate your employment at any time. This Grant Agreement, the Grant Notice, and the Plan, including any future amendments thereto, shall be binding upon you, your estate, any person succeeding to your rights hereunder and any successor or successors of the Company. The RSUs do not confer to you or any person succeeding to your rights hereunder any rights of a shareholder of the Company unless and until shares of Common Stock are in fact issued to you or such person in connection with the settlement of the RSUs.

No Rights to Continued Employment. Neither this Plan nor the grant of any Option hereunder shall confer any right on any employee to remain in the employ of the Company or any Participating Subsidiary, or restrict the right of the Company or any Participating Subsidiary to terminate such employee's employment.
