AGREEMENT AND GENERAL RELEASE

This Agreement and General Release (“Agreement”) is made and entered into by and between Smith Micro Software, Inc. (“Employer”) on the one hand, and Von Cameron, his heirs, executors, administrators, successors and assigns (collectively, “Employee”) on the other. Employer and Employee agree that:

2.       Consideration. In consideration for signing this Agreement and compliance with the promises made herein, Employer agrees to pay Employee a lump sum amount of $83,333, less lawful deductions, fourteen (14) calendar days after the Employer’s receipt of an original of this Agreement signed by Employee, provided Employee does not revoke this Agreement as provided in section 4 below. In addition, Employer will pay the amount of Q2 and Q3 bonuses along with 31 days pro-rated portion of Q4 bonus, as calculated based on the Company’s operating results, in the ordinary course of business, anticipated to be early August, early November, 2013 and early February 2014 and subject to section 4 below.

Employer also agrees that, if Employee properly and timely elects to continue medical and dental coverage under the Cigna plan in accordance with the continuation requirements of COBRA, Employer shall reimburse the cost of the premium for such coverage for up to four (4) months beginning July 1, 2013 and ending on October 31, 2013. Thereafter, Employee shall be entitled to elect to continue such COBRA coverage for the remainder of the COBRA period, at Employee’s own expense, subject to the provisions of the American Recovery and Reinvestment Act of 2009.

3.       No Consideration Absent Execution of this Agreement. Employee understands and agrees that he would not receive the amount specified in section 2 above, except for his execution of this Agreement and the fulfillment of the promises contained in this Agreement.

predecessors, insurers, successors and assigns, and their current and former employees, attorneys, officers, directors and agents thereof both individually and in their business capacities (collectively, “Releasees”) of and from any and all claims, known and unknown, asserted or unasserted, which Employee has or may have against Releasees as of the date of execution of this Agreement, including, but not limited to, any alleged violation of:

6.           Waiver of Claims. Employee and Employer understand and agree that this Agreement extends to all claims, of every nature and kind whatsoever, known or unknown, suspected or unsuspected, enumerated in this Agreement or otherwise. Employee and Employer understand and agree that he or it may hereafter discover facts different from or in addition to those he or it now knows or believes to be true in respect to the claims, demands, damages, liabilities, actions or causes of action herein released, and Employee and Employer agree that this Agreement is and will remain in effect in all respects as a complete and general release as to the matters to be released, notwithstanding any such different and additional facts.

8.      Restricted Shares Vesting. A total of 23,980 restricted shares will be accelerated to the termination date. Accelerated shares will be processed in the same amount and manner set forth in the Restricted Stock Award Agreement entered into between Employer and Employee. These shares will also be eligible for a tax gross-up payment or share withholding procedure similar to Employee’s previous stock vesting transactions.

11.       No Disparagement. Employee agrees not to make any disparaging or negative statements about Employer after his employment ends. Employer agrees that it will make a neutral reference when its human resources department is contacted for information about the Employee. This reference will include only the Employee’s dates of employment and position(s).

12.       Governing Law and Interpretation. This Agreement will be governed and conformed in accordance with the laws of the state of California without regard to its conflict of laws provision. In the event the Employee or Employer breaches any provision of this Agreement, Employee and Employer affirm that either may institute an action specifically to enforce any term or terms of this Agreement and/or seek any damages for breach.

Nothing in this Agreement is intended to waive or release any claims arising out of a breach of this Agreement, and such claims are expressly omitted from the release in this Agreement.
