PROXY STATEMENT
FOR ANNUAL MEETING OF STOCKHOLDERS
To Be Held June 28, 2007

General

     This Proxy Statement and the enclosed proxy card are furnished in connection with the 2007 Annual Meeting of Stockholders (the “Annual Meeting”) of Smith Micro Software, Inc. (“Smith Micro,” the “Company,” “we,” “our” or “us”), which will be held at our corporate headquarters located at 51 Columbia, Aliso Viejo, California 92656, on Thursday, June 28, 2007, at 10:00 a.m., Pacific Time. Stockholders of record at the close of business on April 30, 2007, the record date, are entitled to notice of and to vote at the Annual Meeting and any adjournment thereof. This Proxy Statement, the enclosed proxy card and the Smith Micro Annual Report on Form 10-K for the fiscal year ended December 31, 2006 (the “Annual Report”), were first mailed on or about May 7, 2007, to stockholders of record as of the record date.

Purpose of the Meeting

     The specific proposals to be considered and acted upon at the Annual Meeting are summarized in the accompanying Notice and are described in more detail in this Proxy Statement. We are not aware of any matter to be presented other than those described in this Proxy Statement.

Voting

     Our outstanding common stock, par value $0.001 per share (the “Common Stock”) is the only class of securities entitled to vote at the Annual Meeting. Common stockholders of record on April 30, 2007, the record date, are entitled to notice of and to vote at the Annual Meeting. As of April 30, 2007, there were 29,631,649 shares of Common Stock outstanding and approximately 123 holders of record according to information provided by our transfer agent. Each share of Common Stock is entitled to one vote. Stockholders may not cumulate votes in the election of directors. A majority of the outstanding shares of Common Stock entitled to vote at the Annual Meeting will constitute a quorum.

     All votes will be tabulated by our inspector of elections for the Annual Meeting who will separately tabulate affirmative and negative votes, abstentions and “broker non-votes” (i.e., shares held by a broker or other nominee having discretionary power to vote on some matters but not others). Abstentions and broker non-votes are counted as present for purposes of determining the presence or absence of a quorum for the transaction of business. Abstentions will be counted towards the tabulations of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. In the election of directors, the nominee receiving the highest number of affirmative votes shall be elected; broker non-votes and votes marked “withhold” will not affect the outcome of the election. Proposal II requires the affirmative vote of a majority of shares present in person or represented by proxy at the Annual Meeting and entitled to vote. Broker non-votes will not be counted for purposes of determining whether such proposals have been approved.

Proxies

     Properly executed proxies will be voted in the manner specified therein. If no direction is made on the proxies, such properly executed proxies will be voted FOR the election of the nominees named under the caption “Election of Directors” as our directors, and FOR the ratification of the selection of Singer Lewak Greenberg & Goldstein LLP as our independent registered public accounting firm for the 2007 fiscal year. You may revoke or change your proxy at anytime before the Annual Meeting by filing with the corporate Secretary at our principal executive offices at 51 Columbia, Aliso Viejo, California 92656, a notice of revocation or another signed Proxy with a later date. You may also revoke your proxy by attending the Annual Meeting and voting in person. Your attendance at the Annual Meeting does not, by itself constitute a revocation of your proxy. Please note that if your shares are held of record by a broker, bank or other nominee, you will not be able to vote in person at the Annual Meeting unless you have obtained and present a proxy issued in your name from the record holder.

Voting Electronically via the Internet

     If your shares are registered in the name of a bank or brokerage firm, you may be eligible to vote your shares electronically over the Internet. A large number of banks and brokerage firms provide eligible stockholders who receive a paper copy of the Annual Report and Proxy Statement the opportunity to vote in this manner. If your bank or brokerage firm allows for this, your voting form will provide instructions for such alternative method of voting. If your voting form does not reference Internet information, please complete and return the paper Proxy in the self-addressed, postage prepaid envelope provided.

Solicitation

     The enclosed proxy is being solicited by our Board of Directors, and Smith Micro will bear the entire cost of solicitation, including the preparation, assembly, printing and mailing of this Proxy Statement, the proxy card and any additional solicitation materials furnished to the stockholders. Copies of solicitation materials will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward solicitation material to such beneficial owners. We may reimburse such persons for their costs in forwarding the solicitation materials to such beneficial owners. In addition, the original solicitation of proxies by mail may be supplemented by a solicitation by Internet or other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services, although we may reimburse reasonable out-of-pocket expenses. Except as described above, we do not presently intend to solicit proxies other than by mail.

Deadline for Receipt of Stockholder Proposals

     Stockholders may present proposals for action at a future meeting only if they comply with the requirements of the proxy rules established by the Securities and Exchange Commission (“SEC”) and our Bylaws. Stockholder proposals that are intended to be presented at our 2008 Annual Meeting of Stockholders (the “2008 Annual Meeting”) and included in the proxy solicitation materials related to that meeting must be received by us no later than January 8, 2008, which is 120 calendar days prior to the anniversary date of the mailing of this Proxy Statement. Stockholders are also advised to review our Bylaws which contain additional advance notice requirements, including requirements with respect to advance notice of stockholder proposals and director nominations. Under our current Bylaws, the deadline for submitting a stockholder proposal is not less than 30 days and no more than 90 days prior to the date of the Annual Meeting and the deadline for submitting a nomination for a director is not less than 60 days prior to the date of the Annual Meeting. Stockholder proposals must be in writing and should be addressed to the corporate Secretary at our principal executive offices located at 51 Columbia, Aliso Viejo, California 92656.

     In addition, the proxy solicited by the Board of Directors for the 2008 Annual Meeting will confer discretionary authority to vote on any stockholder proposal presented at that meeting, unless we receive notice of such proposal not later than March 23, 2008, which is 45 calendar days prior to the anniversary date of the mailing of this Proxy Statement. It is recommended that stockholders submitting proposals direct them to our corporate Secretary and utilize certified mail, return receipt requested in order to provide proof of timely receipt. The Chairman of the Annual Meeting reserves the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these and other applicable requirements, including conditions set forth in our Bylaws and conditions established by the Securities and Exchange Commission.

     We have not been notified by any stockholder of his or her intent to present a stockholder proposal from the floor at this year’s Annual Meeting. The enclosed proxy grants the proxy holders discretionary authority to vote on any matter properly brought before the Annual Meeting.

MATTERS TO BE CONSIDERED AT ANNUAL MEETING

PROPOSAL 1:

ELECTION OF DIRECTORS

     Our Amended and Restated Certificate of Incorporation and Bylaws provide for our Board of Directors to be divided into three classes, as nearly equal in number as is reasonably possible, serving staggered terms that expire in different years. At each annual meeting of stockholders, the successors to the class of directors whose term expires are elected to hold office for a term of three years. The term of one class of directors expires at each annual meeting. The preceding notwithstanding, directors serve until their successors have been duly elected and qualified or until they earlier resign, become disqualified or disabled, or are otherwise removed.

     Our Board currently has six directors: Thomas G. Campbell, Samuel Gulko, Ted Hoffman, William C. Keiper, William W. Smith, Jr. and Gregory J. Szabo. The class whose term expires at this Annual Meeting contains two directors. The Nominating Committee of the Board of Directors selected, and the Board of Directors approved, Mr. Gulko and Mr. Szabo as nominees for election at the Annual Meeting to the class being elected at this meeting. The enclosed proxy will be voted, unless authority is withheld or the proxy is revoked, FOR the election of each nominee for election named below to hold office until the date of our 2010 Annual Meeting or until his successor has been duly elected and qualified or until he earlier resigns, becomes disqualified or disabled, or is otherwise removed. Each returned proxy cannot be voted for a greater number of persons than the nominees named on the proxy. In the unanticipated event that a nominee becomes unable or declines to serve at the time of the Annual Meeting, the proxies will be voted for a substitute person selected by the Nominating Committee of the Board of Directors and approved by the Board of Directors. Each nominee for election has agreed to serve if elected, and management has no reason to believe that such nominee will be unavailable to serve.

     Stockholders may communicate with members of the Board of Directors by mail addressed to the full Board, a specific member of the Board or to a particular committee of the Board at our principal executive offices located at 51 Columbia, Aliso Viejo, California 92656.

     Although we do not have a formal policy regarding attendance by members of the Board of Directors at our annual meeting of stockholders, directors are encouraged to attend our annual meetings. One of our current directors attended our annual meeting of stockholders in 2006.

     The Board of Directors has three committees: an Audit Committee, a Compensation Committee, and a Governance and Nominating Committee. Each of these committees has adopted a written charter. All members of the committees are appointed by the Board of Directors and are non-employee directors and independent within the meaning of the Nasdaq Stock Market listing standards.

The Audit Committee reviews our financial statements and accounting practices, makes recommendations to the Board of Directors regarding the selection of our independent registered public accounting firm and reviews the results and scope of our annual audit and other services provided by our independent registered public accounting firm. The Audit Committee also is responsible for establishing, and has established, procedures for the receipt, retention and treatment of complaints regarding accounting, internal

accounting controls or auditing matters, and for the confidential, anonymous submission by our employees of concerns regarding questionable accounting or auditing matters. In addition, all related party transactions are reviewed and approved by the Audit Committee.

The designation does not impose on Mr. Gulko any duties, obligations or liability that are greater than are generally imposed on him as a member of the Audit Committee and the Board, and his designation as an Audit Committee financial expert pursuant to this SEC requirement does not affect the duties, obligations or liability of any other member of the Audit Committee or Board.

There are no differences in the manner in which the Nominating Committee evaluates a candidate that is recommended for nomination for membership on our Board of Directors by a stockholder. The Nominating Committee has not received any recommended nominations from any of our stockholders in connection with this Annual Meeting. Each of the current nominees for this Annual Meeting is standing for re-election.

     The Nominating Committee will consider stockholder nominations for directors submitted in accordance with the procedure set forth in Article II, Section 12 of our Bylaws.

     The Board of Directors recommends a vote FOR the nominees named above or their substitutes as set forth herein.

PROPOSAL 2:

RATIFICATION OF APPOINTMENT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

     On April 17, 2005, Deloitte & Touche LLP (“Deloitte”) advised the Audit Committee that it declined to stand for re-appointment as our independent registered public accounting firm, and would resign upon completion of its review of our interim financial statements to be included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2005. Deloitte’s report on our consolidated financial statements for the years ended December 31, 2003 and 2004 did not contain any adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles. During the two year period ended December 31, 2004, and the period from January 1, 2005, through the date of Deloitte’s resignation, there were no disagreements between us and Deloitte on any matter of accounting principles or practice, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Deloitte’s satisfaction, would have caused Deloitte to make reference to the subject matter of such disagreements in connection with the issuance of its report on our financial statements. During the two year period ended December 31, 2004, and the period from January 1, 2005, through the date of its resignation, Deloitte did not advise us that any “reportable events” (as described in Item 304(a)(1)(v) of Regulation S-K) had occurred.

     On May 27, 2005, the Audit Committee appointed BDO Seidman, LLP (“BDO”) as our independent registered public accounting firm for the fiscal year ending December 31, 2005. During the two year period ended December 31, 2004 and the period from January 1, 2005 through the date BDO was engaged, we did not consult with BDO regarding any of the items described under Item 304(a)(1)(iv)(b), Item 304(a)(2) or Item 304(b) of Regulation S-K. On December 8, 2005, our Audit Committee dismissed BDO as our independent registered public accounting firm. On the same date, our Audit Committee engaged Singer Lewak Greenbaum & Goldstein LLP (“Singer Lewak”) as our independent registered public accounting firm to audit our financial statements for the year ending December 31, 2005. BDO had not been asked to provide, nor has it provided, any report on our financial statements. We did not have any disagreement with BDO, regardless whether resolved, on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure. During the period from May 27, 2005, when BDO was initially engaged, through the date of its dismissal, BDO did not advise us that any “reportable events,” as defined in Item 304(a)(1)(v) of Regulation S-K, had occurred.

     During the two year period ended December 31, 2004, and the period from January 1, 2005 through the date Singer Lewak was engaged, we did not consult with Singer Lewak regarding any of the items described under Item 304(a)(1)(iv)(b), Item 304(a)(2) or Item 304(b) of Regulation S-K.

     The Audit Committee has selected Singer Lewak as the Company’s independent auditors for the fiscal year ending December 31, 2007 and has further directed that the selection of the independent auditors be submitted for ratification by the stockholders at the Annual Meeting. Representatives of Singer Lewak are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

     Stockholder ratification of the selection of Singer Lewak as the Company’s independent auditors is not required by the Company’s Bylaws or otherwise. However, the Board of Directors is submitting the selection of Singer Lewak to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm.

COMPENSATION DISCUSSION AND ANALYSIS

Overview

     This compensation discussion and analysis explains the material elements of the compensation awarded to, earned by, or paid to each of our executive officers who served as our named executive officers during the last completed fiscal year.

Compensation Program Objectives and Philosophy

     The compensation committee of our board of directors currently oversees the design and administration of our executive compensation program. Our compensation committee’s primary objectives in structuring and administering our executive officer compensation program are to:

     1. attract, motivate and retain talented and dedicated executive officers;

     2. tie annual and long-term cash and stock incentives to achievement of measurable corporate and individual performance objectives; and

     3. reinforce business strategies and objectives for enhanced stockholder value

     To achieve these goals, our compensation committee maintains compensation plans that tie a portion of executives’ overall compensation to key strategic goals such as financial and operational performance, as measured by metrics such as revenue and sales. Our compensation committee evaluates individual executive performance with a goal of setting compensation at levels the committee believes are comparable with those of executives at other companies of similar size and stage of growth, while taking into account our relative performance and our own strategic goals.

     The principal elements of our executive compensation program are base salary, cash bonus awards, long-term equity incentives in the form of stock options and/or restricted stock, other benefits and perquisites, post-termination severance and acceleration of stock option vesting for certain named executive officers upon termination and/or a change in control. Our other benefits and perquisites consist of life and health insurance benefits and a qualified 401(k) savings plan.

     We view these components of compensation as related but distinct. Although our compensation committee does review total compensation, we do not believe that significant compensation derived from one component of compensation should negate or offset compensation from other components. We determine the appropriate level for each compensation component based in part, but not exclusively, on competitive benchmarking consistent with our recruiting and retention goals, our view of internal equity and consistency, and other considerations we deem relevant, such as rewarding extraordinary performance.

Determination of Compensation Awards

     Our compensation committee performs at least annually a strategic review of our executive officers’ compensation to determine whether they provide adequate incentives and motivation to our executive officers and whether they adequately compensate our executive officers relative to comparable officers in other similarly situated companies. Our compensation committee’s most recent review occurred in February 2007. Our compensation committee also met individually with members of our senior management to learn about our business operations and strategy, key performance metrics and target goals, and the labor and capital markets in which we compete, and developed recommendations that were reviewed and approved by our board of directors.

     Our compensation committee meetings typically have included, for all or a portion of each meeting, not only the committee members but also our chief executive officer and our chief financial officer. For compensation decisions, including decisions regarding the grant of equity compensation, relating to executive officers other than our chief executive officer, our compensation committee typically considers recommendations from our chief executive officer.

Benchmarking of Compensation

     The compensation committee believes it is important when making its compensation-related decisions to be informed as to current practices of similarly situated companies. As a result, the compensation committee reviews third-party surveys and other information collected from public sources for executive officers at peer companies. The compensation committee also receives the recommendation of our chief executive officer on compensation for other executive officers. Historically, the compensation committee has not engaged third party consultants to advise the compensation committee on compensation matters, but we may do so in the future. While benchmarking may not always be appropriate as a stand-alone tool for setting compensation due to the aspects of our business and objectives that may be unique to us, we generally believe that gathering this information is an important part of our compensation-related decision-making process.

Base Compensation

     We provide our named executive officers and other executives with base salaries that we believe enable us to hire and retain individuals in a competitive environment and to reward individual performance and contribution to our overall business goals. We review base salaries for our named executive officers annually in February and increases are based on our performance and individual performance. We also take into account the base compensation that is payable by companies that we believe to be our competitors and by other public companies with which we believe we generally compete for executives. The base salary of our chief executive officer, Mr. Smith, is reviewed and recommended by our compensation committee and approved by our full board of directors with Mr. Smith abstaining, and had been set at $350,000 in 2006 and will remain at that amount for 2007. Our compensation committee and our board determined that this salary would provide a salary commensurate with Mr. Smith’s experience and would recognize his contributions to our recent growth. Additionally, our compensation committee recommended, and our board approved, base salary increases for 2007 as follows:

Andrew Schmidt		$260,000 (a 9% increase from 2006)
David Sperling		$210,000 (a 6.4% increase from 2006)
William R. Wyand		$185,000 (a 7.7% increase from 2006)
Christopher Lippincott		$180,000 (a 9% increase from 2006)

Cash Bonus Awards

     As part of our compensation program and in order to maintain appropriate financial incentives, our executive officers are eligible for cash bonus compensation pursuant to an annual cash bonus plan. Under the plan, cash bonuses are determined and paid each fiscal year on a quarterly basis based upon the achievement of certain performance objectives. Our cash bonus plan is designed to focus our management on achieving key corporate financial objectives, to motivate certain desirable behaviors and to reward achievement of our key corporate financial objectives and individual goals. Our bonus plan contains between one and two performance objectives with a dollar value ascribed to each objective so that the sum total equals the approved cash bonus potential for each executive officer, according to our bonus plan. In 2006 the objective(s) (i) for Messrs. Smith and Schmidt were: (1) revenue achievement, and (2) profitability achievement; (ii) for Messrs. Sperling and Kahn was revenue achievement; and (iii) for Messrs. Wyand and Lippincott was sales attainment. We believe that the performance objectives are moderately difficult to achieve and that performance at a high level while devoting full time and attention to their responsibilities is required for our executive officers to earn their respective cash bonuses.

     For 2006, based on the achievement of the objectives for our executive officers under our bonus plan, we paid bonuses of $45,527 to Mr. Smith, $34,494 to Mr. Schmidt, $63,149 to Mr. Sperling, $48,500 to Mr. Kahn, $135,385 to Mr. Wyand and $57,376 to Mr. Lippincott. The cash bonuses paid to our chief executive officer accounted for approximately 5% of his total compensation in 2006. For our other named executive officers in 2006, their cash bonuses, on average, accounted for 5.6% to 28.1% of their total compensation.

     For 2007, our compensation committee has worked with our senior management to establish the target bonus amounts and performance objectives under our bonus plan. The target bonuses for our executive officers for the 2007 fiscal year are as follows: $75,000 for Mr. Smith, $65,000 for Mr. Schmidt, $46,000 for Mr. Sperling, $60,000 for Mr. Kahn, $145,000 for Mr. Wyand and $30,000 for Mr. Lippincott.

     The performance objectives for fiscal year 2007, described below, have been approved by the compensation committee. For each performance objective there is a formula that establishes a specific cash payout for each executive officer based on a percentage of the individual’s target bonus amount. For the 2007 fiscal year, the formula for payments under the bonus plan will be based on the achievement of the following objectives: (1) revenue attainment, (2) profitability and (3) cost savings (in some cases). With respect to these objectives, we have to achieve a specified minimum in order for the objective to be considered in the determination of bonuses.

     The compensation committee may also award discretionary bonuses throughout the year based on our achievements and the individual’s contributions to those achievements, if it deems such an award to be appropriate. For 2006, the compensation committee awarded the following discretionary bonuses: $31,195 to Mr. Sperling, $20,000 to Mr. Wyand and $16,000 to Mr. Lippincott.

Equity Compensation

     We believe that for growth companies in the technology sector, equity awards are a significant compensation-related motivator in attracting and retaining executive-level employees. Accordingly, we have provided our named executive officers and other executives with long-term equity incentive awards that incentivize those individuals to stay with us for long periods of time, which in turn should provide us with greater stability over such periods than we would experience without such awards. While the majority of our long-term equity compensation awards historically have also been in the form of stock options, we provided grants of restricted stock to each of our executive officers in 2006. We felt that granting restricted stock in 2006 provided additional incentive to our executives by providing them with immediate stock ownership, which helped align their interests with those of our stockholders.

     We account for equity compensation paid to our employees under the rules of SFAS No. 123R, which requires us to estimate and record compensation expense over the vesting period of the award. All equity awards to our employees, including executive officers, and to our directors have been granted and reflected in our consolidated financial statements, based upon the applicable accounting guidance, at fair market value on the grant date.

     We grant equity compensation to our executive officers and other employees under our 2005 Stock Option/Stock Incentive Plan, which we refer to as the 2005 Plan.

     Generally, we grant long-term equity awards to our named executive officers upon commencement of their employment, and the terms of those awards typically vest over four years. Additionally, from time to time, we grant subsequent long-term equity awards to our named executive officers based upon a number of factors, including: rewarding executives for superior performance, maintaining a sufficient number of unvested long-term equity awards as a means to retain the services of such executives, providing increased motivation to such executives and ensuring that the total long-term equity awards are competitive with those of other companies competing for our named executive officers.

     Restricted Stock. Over our history we have made several grants of restricted stock to our executive officers. On March 8, 2006, restricted stock grants were made to William W. Smith, Jr. of 50,000 shares and to Andrew Schmidt of 25,000 shares. On April 20, 2006 grants of 30,000 shares were made to William W. Smith, Jr., Andrew Schmidt, David Sperling, Jonathan Kahn, William R. Wyand and Christopher Lippincott. Each of these grants vested equally over 24 months. We have also granted restricted stock to certain of our directors. See “—Summary of Director Compensation” below for additional information.

     Stock Options. There were no stock option grants made to executive officers in 2006. In 2007 options for 200,000 shares were granted to William W. Smith, Jr. and options for 100,000 shares each were granted to Andrew Schmidt, David Sperling, Jonathan Kahn, William R. Wyand and Christopher Lippincott. The exercise price of these options was $12.55. Each option vests 25% after one year, with the remainder vesting pro rate over the succeeding 36 month period.

     For a discussion of the determination of the fair market value of these grants, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies — Stock-Based Compensation.”

     Our stock options have a 10-year contractual term. In general, the option grants are also subject to post-termination and change in control provisions. These terms are more fully described below in “—Employment Agreements” and “—Potential Payments upon Termination or Change in Control.”

Executive Benefits and Perquisites

     We provide the opportunity for our named executive officers and other executives to receive certain perquisites and general health and welfare benefits. We also offer participation in our defined contribution 401(k) plan. We provide a 20% match on all eligible employee contributions to our 401(k) plan. We provide these benefits to create additional incentives for our executives and to remain competitive in the general marketplace for executive talent.

Change in Control and Severance Benefits

     We provide the opportunity for certain of our named executive officers to receive additional compensation or benefits under the severance and change in control provisions contained in their employment agreements. We provide this opportunity to attract and retain an appropriate caliber of talent in key positions. Our severance and change in control provisions for certain of our named executive officers are summarized below in “— Employment Agreements” and “— Potential Payments Upon Termination or Change in Control.” Our analysis indicates that our severance and change in control provisions are reasonable and consistent with the provisions and benefit levels of other companies disclosing such provisions in public SEC filings.

Executive Compensation

Employment Agreements

     Letter Agreement with Andrew C. Schmidt

     Effective on June 14, 2005 we entered into a letter agreement with Andrew C. Schmidt, our Chief Financial Officer. The agreement provides for an initial base salary of $220,000 per annum and eligibility to receive bonus awards at the discretion of the compensation committee of the board of directors. Mr. Schmidt is also eligible to participate in any and all plans providing general benefits to our employees, subject to the provisions, rules and regulations applicable to each such plan. For our 2007 fiscal year, the Board of Directors approved an increase in Mr. Schmidt’s base compensation to $260,000 plus a bonus opportunity of $65,000.

     Mr. Schmidt’s employment letter agreement also provides that he is eligible to participate in our 2005 Stock Option Plan. In 2005 Mr. Schmidt was granted options to purchase 100,000 shares of stock at an exercise price of $4.95, which vested over two years. In 2006 Mr. Schmidt received grants of 55,000 shares of restricted stock, which vest ratably over 24 months. In 2007, Mr. Schmidt has been granted options to purchase 100,000 shares of stock at an exercise price of $12.55. These options vest over four years.

     Mr. Schmidt’s employment may be terminated at any time, with or without cause and with or without notice, by Mr. Schmidt or by us. If Mr. Schmidt’s employment is terminated by us without cause within twelve months following a Corporate Transaction (as defined in the agreement), we will provide Mr. Schmidt payment of salary for the six months following the termination of employment.

     The letter agreement states that Mr. Schmidt’s employment is of no set duration.

     Employment Agreement with William Wyand

     We entered into an employment agreement on April 9, 1999 with William Wyand in connection with our purchase of STF Technologies, where Mr. Wyand was President and Chief Executive Officer. The employment agreement provides for an initial base salary of $150,000 per annum, plus commissions and an annual bonus based on the attainment of certain targets. Mr. Wyand is also eligible to participate in any and all plans providing general benefits to our employees, subject to the provisions, rules and regulations applicable to each such plan. The Board has approved an increase in Mr. Wyand’s base compensation to $175,000 and changes to his commission schedule, effective on January 1, 2006. In 2007, the Board increased Mr. Wyand’s base compensation to $185,000 and paid a one-time bonus of $25,000.

     Pursuant to the agreement, on April 9, 1999 we granted Mr. Wyand an option to purchase 50,000 shares of our common stock at an exercise price of $2.00. This option vested 25% after one year, with the remainder vesting pro rata over the succeeding 36 month period.

     Mr. Wyand’s employment may be terminated at any time, with or without cause and with or without notice, by Mr. Wyand or by us. If Mr. Wyand’s employment is terminated by us other than for cause (as defined in the agreement), we will provide Mr. Wyand payment of salary for six months following the termination of employment.

     The agreement was for an initial term of one year. After the expiration of such initial term, the agreement automatically renews each year for a period of one additional year, on the same terms and conditions, unless either party gives the other notice of non-renewal at least one month prior to the end of the current term. We may, in our sole discretion, elect to pay Mr. Wyand the equivalent of one month base salary in lieu of notice in the event of non-renewal of the agreement.

     Employment Agreement with Jonathan Kahn

     We entered into an employment agreement on July 1, 2005 with Jonathan Kahn in connection with our purchase of Allume Systems, Inc., where Mr. Kahn was President. The employment agreement provides for an initial base salary of $200,000 per annum, plus an annual bonus based on the attainment of certain targets. Mr. Kahn is also eligible to participate in any and all plans providing general benefits to our employees, subject to the provisions, rules and regulations applicable to each such plan. The Board has approved changes to his commission schedule, effective on April 1, 2007. The employment agreement is for a term of three years.

     Mr. Kahn’s employment may be terminated at any time, with or without cause and with or without notice, by Mr. Kahn or by us. If Mr. Kahn’s employment is terminated by us other than for cause (as defined in the agreement) or if Mr. Kahn terminates his employment for good reason following a Change of Control (as defined in the agreement), we will provide Mr. Kahn a severance payment equal to eighteen months at his then-current base salary. Such amount shall be payable in equal monthly increments over the period following termination. In addition, if we terminate Mr. Kahn without cause or if he terminates his employment for good reason following a Change of Control: (i) we will provide Mr. Kahn with continuation of medical, health and life insurance benefits, at the same benefit level at which he was participating on the date of termination, for such eighteen month period, and (ii) all of Mr. Kahn’s unvested stock options will immediately vest and be exercisable in full within two years of termination.

     Agreement with William W. Smith, Jr.

     In June 2005, the Company entered into an agreement with William W. Smith, Jr., Chief Executive Officer, pursuant to which the Company agreed to a lifetime payment of $6,000 annually, subject to annual increases of 5%, in connection with his future retirement or resignation from employment by the Company. The agreement provides that the Company may, at its option, discharge its obligations under the agreement by purchasing a single premium annuity for the benefit of Mr. Smith, the estimated cost of which was approximately $150,000.

     Other than as disclosed above, none of the Named Executive Officers has an employment agreement with us, and the employment of each of the Named Executive Officers may accordingly be terminated at any time at the discretion of the Board of Directors.

Potential Payments Upon Termination or Change in Control

     Mr. Schmidt

     Pursuant to the employment letter agreement with Mr. Schmidt, if his employment is terminated without cause within twelve months following a Corporate Transaction he is entitled to a severance benefit equal to six months base salary, subject to required withholding and payable in accordance with our regular and customary payroll practices. Assuming the employment of Mr. Schmidt were to be terminated without cause within twelve months following a Corporate Transaction as of December 31, 2006, he would be entitled to be paid $120,000 over the six month period following such termination, subject to required withholding and in accordance with our regular and customary payroll practices. We are not required to make any cash payments to Mr. Schmidt if his employment is terminated by us for cause or on account of death or disability or by Mr. Schmidt.

     For purposes of Mr. Schmidt’s employment letter agreement, (i) “Corporate Transaction” is defined as any of the following stockholder approved transactions to which we are a party: (a) a merger or consolidation in which securities possessing more than fifty percent (50%) of the total combined voting power of our outstanding securities are transferred to a person or persons different from the persons holding those securities immediate prior to such transaction, or (b) the sale, transfer or other disposition of all or substantially all of our assets in complete liquidation or dissolution of Smith Micro; and (ii) “cause” is not defined.

     Mr. Schmidt is bound by the terms of a Proprietary Information and Inventions Agreement which survives the termination of his employment. This agreement provides in part that he will not disclose our confidential information to any third party.

     Mr. Wyand

     Pursuant to the employment agreement with Mr. Wyand, in the event we terminate Mr. Wyand’s employment other than for cause, he is entitled to receive severance payments equal to six months of salary, payable in accordance with our regular payroll practices during such six month period. Assuming the employment of Mr. Wyand were terminated without cause as of December 31, 2006, he would be entitled to be paid $87,500 over the six month period following such termination in accordance with our regular payroll practices. We are not required to make any cash payments to Mr. Wyand if his employment is terminated by us for cause or on account of death or disability or by Mr. Wyand.

     In connection with a termination without cause under Mr. Wyand’s employment agreement, no payments are due if Mr. Wyand breaches his representations and covenants contained in Article V and Article VI of the employment agreement, which provide that (i) Mr. Wyand is subject to a Proprietary Information and Inventions Agreement (which agreement provides in part that he will not disclose our confidential information and survives his termination), (ii) upon termination of his employment Mr. Wyand will return all our confidential information in his possession to us, (iii) Mr. Wyand will not, for a period of 2 years following termination of his employment, directly or indirectly solicit any of our employees or customers, and (iv) Mr. Wyand will not, for a period of 6 months following termination of his employment without cause, directly or indirectly engage in the development, manufacture or distribution of fax/modem and internet protocol/telephony software products.

     For purposes of Mr. Wyand’s employment agreement, “Cause” means (i) the willful refusal of Mr. Wyand to comply with a lawful instruction of our board of directors; (ii) an act or acts of personal dishonesty by Mr. Wyand; (iii) Mr. Wyand’s conviction of any felony; (iv) Mr. Wyand performing any act of race, sex, national origin, religion, disability, age-based or other illegal discrimination or an act of sexual harassment; or (v) Mr. Wyand’s gross negligence, incompetence, willful insubordination or misconduct, failure to abide by our policies, or material breach of any provision of his employment agreement, including without limitation, any representation or covenant contained in Article V or Article VI of the employment agreement.

     Mr. Kahn

     Pursuant to the employment agreement with Mr. Kahn, if we terminate him without cause or if he terminates his employment for good reason upon a change of control, we are obligated to provide Mr. Kahn a severance payment equal to eighteen months at his then-current base salary. Such amount shall be payable in equal monthly increments over the period following termination. In addition, if we terminate Mr. Kahn without cause or if he terminates his employment for good reason upon a Change of Control, we will provide Mr. Kahn with continuation of medical, health and life insurance benefits, at the same benefit level at which he was participating on the date of termination, for such eighteen month period. In addition, the employment agreement provides that all of Mr. Kahn’s unvested stock options will immediately vest and be exercisable in full within two years of the date we terminate him without cause or he terminates his employment for good reason upon a Change of Control.

     Assuming either a Change of Control occurred on December 31, 2006 and Mr. Kahn terminated his employment as a result thereof or we terminated Mr. Kahn without cause on December 31, 2006, Mr. Kahn would be entitled to be paid $300,000 over the eighteen month period following such termination in accordance with our regular payroll practices. In addition, we would have to pay approximately $26,000 to continue Mr. Kahn’s medical, health and life insurance benefits for the eighteen month period following termination. Also, options to purchase 43,750 shares of our common stock having a value of $404,250 (based on the closing price of our common stock on the last trading day of 2006) held by Mr. Kahn would have immediately vested.

     For purposes of Mr. Kahn’s employment agreement, (i) “Change of Control” means a change in a majority of the membership of our board of directors, the sale of all or substantially all of our assets or the merger or consolidation of our company as a result of which Mr. Kahn does not remain a Senior Vice President, and (ii) “cause” means Mr. Kahn’s conviction of, or plea of “guilty” or “no contest” to, a felony involving turpitude, persistent dishonesty or fraud, persistent willful breaches of the material terms of the agreement, or willful neglect of the duties which he is required to perform under his agreement.

     Mr. Smith

     We have an agreement with Mr. Smith pursuant to which we agreed to a lifetime payment of $6,000 annually, subject to annual increases of 5%, in connection with his future retirement or resignation from employment; provided that we may, at our option, discharge our obligations under the agreement by purchasing a single premium annuity for the benefit of Mr. Smith, the estimated cost of which was approximately $150,000. Assuming Mr. Smith’s employment was terminated as of December 31, 2006, and further assuming that we determined to satisfy our obligations under his agreement by purchasing a single premium annuity for the benefit of Mr. Smith, we would have been obligated to expend $150,000 to purchase the annuity.

     Stock Options and Restricted Stock

     In addition, each of our named executive officers holds options and shares of restricted stock that would vest, subject to the satisfaction of certain other conditions included in the option agreements and restricted stock agreements, upon a “Corporate Transaction.” For purposes of these agreements, “Corporate Transaction” is defined as either of the following stockholder-approved transactions to which we are a party: (i) a merger or consolidation in which securities possessing more than fifty percent (50%) of the total combined voting power of our outstanding securities are transferred to a person or persons different from the persons holding those securities immediately prior to such transaction, or (ii) the sale, transfer or other disposition of all or substantially all of our assets in our complete liquidation or dissolution.

Summary of Director Compensation

     Non-employee members of the Board of Directors receive fees of $2,500 quarterly for Board and committee service, and are reimbursed for their out-of-pocket expenses in connection with service on the Board of Directors. Non-employee members of the Board of Directors are eligible to receive periodic option grants pursuant to the Automatic Option Grant Program in effect under the 2005 Stock Option / Stock Issuance Plan and are eligible to receive discretionary awards under the Plan’s Discretionary Option Grant and Stock Issuance Programs, if such Plan is approved and adopted by Stockholders.

     Each non-employee director will receive an option grant for 10,000 shares in connection with his or her initial appointment to the Board of Directors. Each such option will have an exercise price per share equal to the closing sale price per share of Common Stock on the grant date and a maximum term of 10 years measured from the grant date. Each option will be immediately exercisable for all the option shares, but any shares purchased under the option will be subject to repurchase by us, at the option exercise price paid per share, in the event the optionee ceases to serve as a member of the Board of Directors prior to vesting in the option shares. The option shares will vest in a series of four successive equal annual installments over the optionee’s period of service on the Board of Directors, with the first installment to vest upon his or her completion of one year of serving as a member of the Board of Directors measured from the grant date. The option shares will immediately vest in full upon certain changes in control or ownership or upon the optionee’s death or disability while still serving as a member of the Board of Directors.

     At each Annual Meeting of Stockholders, each individual who will continue to serve as a non-employee member of the Board of Directors will receive an additional option grant for 5,000 shares, provided such individual has served on the Board of Directors for at least six months. Each option will have an exercise price per share equal to the closing sale price per share of Common Stock on the date of the Annual Meeting and a maximum term of 10 years measured from such date, subject to earlier termination upon the optionee’s cessation of service on the Board of Directors. The option will be immediately exercisable for all the option shares, but any shares purchased under the option will be subject to repurchase by us, at the option exercise paid per share, should the optionee stop serving as a member of the Board of Directors prior to the completion of one year of service measured from the grant date. On July 24, 2006, in connection with continuing service on the Board of Directors, each of Messrs. Campbell, Gulko, Hoffman, Keiper and Szabo received option grants of 5,000 shares at an exercise price of $13.97 per share, the fair market value per share of Common Stock on the date of grant. On March 8, 2006, each director received a special discretionary grant of 10,000 shares of Restricted Stock valued at $8.80 per share and vesting in equal installments over the next 12 months. On February 19, 2007, each director received a special discretionary grant of 10,000 shares of Restricted Stock valued at $12.55 per share and vesting in equal installments over the next 12 months.

     Report of the Compensation Committee

     The compensation committee establishes and oversees the design and functioning of our executive compensation program. We have reviewed and discussed the foregoing Compensation Discussion and Analysis with the management of the Company. Based on this review and discussion, we recommended to the Board of Directors that the Compensation Discussion and Analysis be included in our Proxy Statement for the 2007 Annual Meeting.

Certain Relationships and Related Transactions

     Since January 1, 2006, there has not been, nor is there currently proposed, any transaction or series of similar transactions to which we were or are a party in which the amount involved exceeds $120,000 and in which any director, executive officer or beneficial holder of more than 5% of any class of our voting securities or members of such person’s immediate family had or will have a direct or indirect material interest.

Procedures for Approval of Related Party Transactions

     Pursuant to the charter of our audit committee, all transactions between us and any of our directors, executive officers or related parties are subject to the review by our audit committee.

Board Member Independence

     The Board of Directors has determined that, except for Mr. Smith, all of the members of the Board of Directors are “independent” as independence is defined in the Nasdaq Stock Market qualification standards. Mr. Smith is not considered independent because he is currently employed by the Company.

Compensation Committee Interlocks and Insider Participation

     In fiscal 2006, the members of the Company’s Compensation Committee were Messrs. Campbell and Keiper, who are both non-employee directors of the Company. None of such committee members (i) was, during fiscal 2006, an officer or employee of the Company or any of its subsidiaries, (ii) was formerly an officer of the Company or any of its subsidiaries, or (iii) had any relationship requiring disclosure by the Company pursuant to any paragraph of Item 404 of SEC Regulation S-K.

     In fiscal 2006, (1) no executive officer of the Company served as a member of a board of directors or compensation committee of any entity that has one or more executive officers serving as a member of the Company’s Compensation Committee; and (2) no executive officer of the Company served as a member of a compensation committee of any entity that has one or more executive officers serving as a member of the Company’s Board of Directors.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

     Section 16(a) of the Exchange Act requires certain of the company’s executive officers, as well as its directors and persons who own more than then percent (10%) of a registered class of the Company’s equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission.

     Based solely on its review of the copies of such forms received by the Company, or written representations from certain reporting person, the Company believes that during the last fiscal year all executive officers and directors complied with their filing requirements under Section 16(a) for all reportable transactions during the year.

ANNUAL REPORT

     Our Annual Report on Form 10-K for the 2006 fiscal year, filed with the Securities and Exchange Commission on March 30, 2007, is being mailed concurrently with this Proxy Statement to all stockholders entitled to notice of and to vote at the Annual Meeting.
