Item 11.    Executive Compensation.

COMPENSATION DISCUSSION AND ANALYSIS

        This compensation discussion and analysis explains our strategy, design and decision-making around our compensation programs and practices as they relate to our named executive officers (the "Named Executive Officers") as defined by the rules promulgated under the Exchange Act. The Compensation Committee has the responsibility for evaluating, approving and recommending to the Board of Directors MRV compensation programs. The Compensation Committee is also responsible for reviewing and evaluating the performance of our CEO and his direct reports, including all of the Named Executive Officers, relative to meeting corporate goals and objectives, and determining compensation levels for these officers based on this evaluation.

Philosophy

        The Compensation Committee believes that the best mix of compensation consists of base salary, performance-based cash bonuses and longer-term equity incentive compensation in the form of stock options. Base salaries are a necessary part of our compensation program and provide executives with a fixed portion of pay that is not performance-based. However, our compensation policies are generally structured to establish a competitive overall compensation package that is heavily weighted towards pay-for-performance. Accordingly, we set base salaries within a market-based range where the midpoint of the range is set below the industry average, and weight accomplishment of corporate performance objectives in the form of incentive bonuses and long-term equity awards.

        In March 2010, the Board of Directors approved the MRV Incentive Compensation Plan (the "Plan"), a performance-based incentive plan applicable to the Named Executive Officers and other management. In order to determine performance-based annual incentive compensation, the Compensation Committee uses factors including certain financial metrics in an effort to align the financial interests of our management, including the Named Executive Officers, with long-term shareholder value creation. Specifically, the Plan ties bonus payments to operating income and revenue targets as well as the achievement of other key performance objectives, which the Compensation Committee and Board deem to be areas of focus for management at this time. For 2011, the Compensation Committee and Board of Directors added operating cash flow to revenue and operating income for the financial objectives, and eliminated the subjective individual performance objective component from the bonus determinations.

        We believe long-term equity awards attract and motivate a highly-talented executive team. Our equity awards are designed to create a strong connection between executive compensation and sustainable long-term shareholder value.

        This philosophy may cause compensation to fluctuate from year to year, and as a result, the Named Executive Officers' compensation levels may be above or below the comparable range of our peers. The Compensation Committee has reviewed our compensation policies and practices for all employees, including executive and non-executive officers, and determined that our compensation programs do not give rise to risks reasonably likely to have a material adverse effect on MRV. The Committee noted several design features of MRV's incentive programs for all executive officers in particular that reduce the likelihood of excessive risk-taking and instead encourage behaviors that support sustainable long-term stockholder value. For example:

•

The program design provides a balanced mix of annual and longer-term incentives.



•

There is a significant weighting towards long-term incentive compensation that discourages short-term risk-taking. Further, in March 2011, our Board approved a framework of stock ownership guidelines for executive officers as well as directors that will require them to maintain a meaningful equity ownership level before they can sell their equity grants, thereby increasing their alignment with long-term stockholder value.



•

Pay-for-performance features such as the minimum operating income target are balanced by appropriate target setting and sliding payout scales.

        To the extent readily determinable, the Compensation Committee considers the anticipated tax treatment to MRV and to the officers and employees of various types of compensation, including the limitation of Section 162(m) of the Internal Revenue Code of 1986, as amended. Some types of compensation and associated deductibility for Company tax purposes depend upon the timing, pricing, vesting or exercise of granted stock options. Interpretations of and changes in the tax laws also affect the deductibility of compensation.

Annual Compensation Methodology

        The Compensation Committee meets annually to review the salary, bonus and stock option award compensation given to the Named Executive Officers and our other highly compensated employees, and reviews and recommends to the Board the incentive plans for each of our subsidiaries and business segments. In addition, the Plan provides for bonuses based on corporate and business unit performance, as applicable, and each year the Compensation Committee will adjust targets pursuant to the Plan. For Named Executive Officers, the Compensation Committee determines whether MRV's financial performance for the preceding year justifies adjustments to base salaries, bonuses and granting of share-based compensation as part of its annual review. In addition, from time to time, the Compensation Committee may consider discretionary bonuses for performance exceeding expectations. The Compensation Committee then recommends its overall compensation plan to the full Board for its approval. The full Board also approves the annual operating plan for the year on which the financial targets of the Plan are based.

        Each year, the Compensation Committee reviews and approves proposed grants of awards for equity incentive plan participants. The total amount of grants and specific grants for senior officers are further recommended to the full Board for approval. Common Stock-based awards are viewed as an important component of total executive pay, aligning compensation with increasing stockholder value and, thus, providing an important benefit to stockholders. Stock options provide a financial reward only in the event that stockholder values are increased. Generally, within compensation programs, stock options are viewed as a cost-effective method for providing equity-based long-term incentive compensation.

The Role of Consultants

        The Compensation Committee retained the services of Farient Advisors, an executive compensation consulting firm in January of 2010, and has continued to engage the consulting firm to present. Farient serves as our outside compensation advisor to provide advice regarding executive compensation decisions. Under the terms of the engagement, Farient provides the Compensation Committee with relevant competitive market data and alternative program designs to consider. Farient has no relationship with MRV other than as our compensation consultant, and will not provide additional services to us without the advance consent of the Compensation Committee.

        To support our Compensation Committee's decision-making in 2011, Farient prepared a comprehensive assessment of compensation for the top 30 executive positions in the six countries in which these positions are located. The review was intended to help the Compensation Committee:

•

understand current competitive positioning across business entities and locations;



•

establish a competitive pay structure that can be applied consistently across MRV, while taking into account country-specific market practices and the relative impact of positions internally; and



•

institute a total compensation philosophy and structure that is weighted towards pay-for-performance.

        The Farient study set forth our competitiveness regarding base salaries, total cash compensation, long-term incentive and total direct compensation. Farient then made recommendations to move MRV into alignment over a two to three year period with our market peers, taking into consideration the Compensation Committee's philosophy to weight overall compensation towards pay-for-performance.

The Role of Executive Officers in Determining Executive Compensation

        Consistent with our Compensation Committee charter, the Compensation Committee, or the Board upon recommendation of the Compensation Committee, makes all final compensation decisions related

to the CEO and his direct reports, which includes all of the Named Executive Officers other than the CEO. However, our CEO and the VP, Human Resources provided information and recommendations to the Compensation Committee, including information relating to the performance of the executive officers, appropriate levels and components of compensation, including equity grants, and the targets for business unit performance or other goals for our annual cash incentives.

        In particular, our typical practice calls for our CEO and senior Human Resources officer to meet with the Compensation Committee at or near the beginning of each fiscal year to present for review and approval, as applicable:

•

An analysis of the 30 most highly compensated employees at MRV, which includes, among other things, their salary, short-term cash incentive bonus, long-term bonus incentive, and benefits.



•

Recommendations on aggregate base salary merit increases by entity and entity bonus pools based on market global compensation data and our financial performance during the prior fiscal year for all employees on the payroll to be included as part of the annual budget process.



•

A recommended corporate performance rating structure for determination of the annual cash incentive awards, which structure will be based upon key metrics that, if achieved, should create positive market performance and a basis for creation of long-term shareholder value.

        At the end of each year, our CEO also assists our Compensation Committee in evaluating our corporate performance and provides performance ratings for each of his direct reports for the recently completed fiscal year. Our compensation philosophy requires that the CEO must seek prior Board approval for all compensation for all executive officers and all individuals with a direct reporting relationship to the CEO. Our Human Resources department also supports the Compensation Committee in various other compensation-related tasks and in some cases acts pursuant to delegated authority to fulfill various functions in administering our compensation programs.

Determination of CEO's Compensation

        Mr. Singh's compensation was determined by the Board of Directors to incentivize him to stabilize the Company's financial results and implement a turnaround plan. He was given a one-year employment agreement beginning on July 1, 2010 with a base salary of $500,000, no bonus, and a grant of 1,750,000 stock options that vest on June 30, 2011. He was also given certain protections on termination without cause prior to the end of his one-year term. These protections are described below under "Employment Agreements and Change of Control Arrangements" beginning on page 17 below. The significant stock option grant was intended to reward him for improving shareholder value during the one-year term. The Board of Directors intends to re-negotiate Mr. Singh's employment agreement this spring for future service, and will be considering such factors as his performance in his first year as MRV's CEO, industry market data provided by Farient as described below, and MRV's financial performance and progress towards the Company's 2011 operating plan.

The Role of Peer Groups and Benchmarking

        Farient Advisors provided a competitive analysis of market pay practices for our executive officers. In consultation with the Compensation Committee, Farient selected a compensation peer group of the following 11 public communication equipment and networking companies that it believed to be similar to MRV based on product and customer profile.

•

Aviat Networks, Inc.



•

Bel Fuse Inc.



•

CIENA Corp.

Opnext, Inc.



•

Sonus Networks, Inc.



•

        The peer group revenues ranged from $200 million to $700 million, with a median annual revenue of approximately $400 million. Two peers from last year's compensation peer group (Finisar Corp. and Oclaro, Inc.) were removed because they were more closely competitive with our optical networking business which we divested in October 2010, and a third peer (F5 Networks, Inc.) was excluded because its revenue exceeded the target revenue range maximum. The peers were also selected due to their substantial international presence, with international revenue near 60% of total revenue. The peer group compensation data was analyzed along with published survey data. The general compensation survey information was provided by iPas Global Technology Survey, Mercer LLC and Towers Watson.

Incentive Compensation Plan and Bonus Targets

        In March 2010, the Board of Directors, upon recommendation by the Compensation Committee, approved the Plan, our annual cash incentive plan, and bonus targets for management and other participants under the Plan. In approving the targets for performance-based cash bonus compensation, the Compensation Committee and Board took the Farient benchmarking study into consideration and the committee's philosophy of weighting performance-based compensation. Mr. Singh has a separate compensation arrangement which he entered into upon his hire on July 1, 2010, and is not a participant in the Plan. Mr. Gorsun's bonus target was set at 45% upon his hire in October 2010. The targets, which were reaffirmed by the Board of Directors in March 2011 for the 2011 fiscal year, are calculated as percentages of base pay, and are as set forth for the following Named Executive Officers:

        The Plan, which sets forth the terms for which an annual bonus is earned, states that a majority of the individual's bonus is based on the operating income and revenues of the business operating unit to which the participant of the Plan belongs. For 2010, the bonuses for participants were also based in part on pre-determined individual objectives, which are aligned with the objectives of the Company. In March 2011, at the recommendation of the Compensation Committee, the Board eliminated the use of individual objectives as a component of the Plan, and instead such annually defined objectives are used in performance evaluations and assist with promotional reviews and determinations. For Mr. King and Mmes. Painter and Tuller, 25% of their 2011 target is allocated to revenue objectives, 25% to operating cash flow objectives and the remaining 50% is allocated to operating income objectives based on the Company's Board-approved consolidated annual operating plan. Mr. Gorsun's bonus target weighs the objectives in the same ratios, but are split 80% to his business unit's approved annual operating plan, and 20% to the Company's consolidated annual operating plan.

Table of Contents

        No bonus will be earned or paid under the Plan in 2011 if operating income falls below 80% of the Board-approved annual operating plan, nor will a bonus be earned unless the participant is employed as of the end of the Plan year, regardless of the reason for termination (unless otherwise set forth in a severance agreement). The target bonus percentages are based on the individual participant's level of responsibility in the Company and market factors.

Policy Governing Grant of Stock Options

        We have adopted a written stock option policy to supplement the provisions of our equity-compensation plans and to govern the timing of stock option grants to employees generally and to officers and directors in particular. The goal in adopting the policy was to seek to ensure that equity-based awards were made in a manner consistent with the terms of the governing plans and at prices and times that are determinable, and only upon approval by the Compensation Committee, or the Board of Directors for certain executives including the Named Executive Officers.

Fiscal Year 2010 and First Quarter 2011 Compensation Decisions

        Base Salary and Annual Cash Bonus.    In 2010, the Compensation Committee requested a study from Farient Advisors for the Company's highly compensated employees based on the peer group identified for last year, which helped the committee benchmark targets for base pay and performance — based compensation, both long- and short-term, In consultation with Farient Advisors and information provided in the study, the Board of Directors increased the base salaries of Mr. King and Ms. Painter to $230,000 each in March 2010. Farient Advisors provided a similar study for 2011 based on the peer group identified above. Taking the compensation study and personal performance into account, at its March 2011 meeting, the Board approved the following base salary increases for the Named Executive Officers:

        Messrs. Singh's and Gorsun's base salaries were set at the time of their hire in 2010 at $500,000 and $230,000, respectively.

        The Board had set the annual incentive bonus targets for Messrs. Lotan and King and Mmes. Painter and Tuller at 75%, 60%, 60% and 40%, respectively, at its March 2010 Board meeting. Mr. Gorsun's target was set at 45% upon his hire, and Mr. Singh does not have an annual incentive bonus target. In March 2011, the Board kept these targets the same as the prior year, but revised the performance objectives to reach the targets as set forth above under "Incentive Compensation Plan and Bonus Targets."

        In March 2011, the Compensation Committee approved bonus payouts for all participants of the Incentive Compensation Plan during 2010. Extraordinary transaction costs related to the sale of Source Photonics and the settlement of litigation with Finisar Corporation were excluded for purposes of calculating achievement of the objectives. The bonus payout amounts paid in March 2011 pursuant to

Table of Contents

the Incentive Compensation Plan for 2010 for the Named Executive Officers ranged from 109 to 110 percent of their targets (with the exception of Mr. Gorsun's partial year payout), and were as follows:

        Mr. Gorsun's bonus was pro rated for the time he was employed by MRV in 2010. In addition to the annual incentive bonus payouts, the Board approved discretionary bonuses in the amounts of $15,000, $25,000 and $7,091 for Mr. King and Mmes. Painter and Tuller in 2010, respectively. The Board wanted to reward Mr. King and Ms. Painter for their dedicated efforts in completing the sale of Source Photonics, Inc. and Source Photonics Santa Clara, Inc. (together, "Source Photonics"), and Ms. Tuller received her bonus for her exceptional efforts with the close of the second quarter financial statements despite finance staff reductions in that period.

        Stock Option Grants.    Pursuant to Mr. Singh's employment agreement, he received 1,750,000 stock options on his hire date, July 1, 2010, that vest in full on June 30, 2011 and have an exercise price equal to the closing price of MRV's Common Stock on July 1, 2010, the date of grant. This option grant exceeded the limits of the 2007 Omnibus Incentive Plan (the "2007 Plan") and therefore were granted outside of the plan. Under the 2007 Plan, on August 13, 2010, 252,728 stock options were granted to Mr. King, 235,476 to Ms. Painter, and 40,000 to Ms. Tuller. As an inducement for Mr. Gorsun to take the position of President of our OCS division, he was granted 250,000 stock options on December 1, 2010 under the 2007 Plan. The options for the Messrs. King and Gorsun and Mmes. Painter and Tuller have an exercise price equal to the closing price of MRV's Common Stock on the date of grant, and vest pro rata over four years in annual increments beginning on the first anniversary of the grant date and accelerate upon a change of control.

        The Compensation Committee believes that equity grants are an important part of long-term variable incentive compensation which aligns management with shareholder value, and as such, the committee approved annual stock option grant amounts for 2011 for specified employees at its March 2011 meeting. The grants for senior officers, including the Named Executive Officers, were further approved by the full Board of Directors at the recommendation of the committee. These stock options continue to have an exercise price equal to the closing price of the share s of MRV's Common Stock on the date of grant, and accelerate upon a change of control. However, they will vest pro rata over three years in annual increments beginning on the first anniversary of the grant date, and if an employee works for a subsidiary, 50% of the unvested stock options shall vest on the change of control of that subsidiary. The grant date for the approved stock options will be June 1, 2011, and the following Named Executive Officers will receive the following number of stock options: Mr. King, 230,000; Ms. Painter, 200,000; and Ms. Tuller, 40,000.

Employee Benefits

        Executives are generally entitled only to benefits consistent with those offered to our other employees. We offer group life, disability, medical, dental and vision insurance and a 401(k) plan.

Compensation Committee Interlocks and Insider Participation

        Messrs. Tartavull and Gillman and Ms. Herman served on the Compensation Committee in 2010, with the exception that Mr. McConnell replaced Mr. Gillman on the committee on May 21, 2010 since Mr. McConnell was not serving on any committees at that time. No member of the Compensation

Summary Compensation Table

        The following table summarizes information regarding compensation paid and the fair value of option grants during each of the past three fiscal years to the Named Executive Officers serving at December 31, 2010.

---

(1)

Ms. Tuller received a discretionary bonus in August 2010 of $7,091 for her work closing the second quarter financial statements despite finance staff reductions in that period. Mr. King and Ms. Painter each received discretionary bonuses in December 2010 in the amounts of $15,000 and $25,000, respectively, for their efforts in completing the sale of Source Photonics. The remainder of the cash bonuses set forth in 2010 for Messrs. King and Gorsun and Mmes. Painter and Tuller were earned in 2010 and paid out in March 2011. In 2009, Mr. King and Ms. Painter received discretionary bonuses to reinstate approximately 35% of the 10% reduction in the base salary incurred the prior nine months and for their work in connection with completing the restatement of our financial statements, in aggregate amounts of $35,995 and $34,670, respectively. The remainder of the cash bonuses set forth in 2010 for Mr. King and Ms. Painter were earned in 2009 and paid out in March 2010. The annual cash bonus earned in 2008 by Mr. King was paid out in January 2009.

(2)

Amounts reflect the aggregate grant date fair value determined by MRV calculated in accordance with Financial Accounting Standards Board ASC 718 Compensation — Stock Compensation ("ASC 718"). Due to a change in the SEC's rules effective February 28, 2010, this column no longer reflects the dollar amount recognized in the current year for financial statement reporting purposes in accordance with ASC 718, but instead, reflects the aggregate grant date fair value on the grant date. Therefore, 2008 amounts differ from those reflected in prior filings. The stated amounts do not reflect whether the recipient will actually realize a financial benefit from the awards. For additional information regarding valuation assumptions, refer to Note 13 (Share-Based Compensation) in the Notes to our financial statements included in our Original Filing.

(3)

None of the Named Executive Officers received perquisites in excess of $10,000, and therefore such amounts are not included in the "All other compensation" or "Total" columns. For each Named Executive Officer, "All other compensation" includes life insurance premiums paid by MRV and contributions made by MRV to the Company's 401(k) savings plan on the officer's behalf.

(4)

Mr. Singh joined MRV as its CEO in July 2010, and has a base salary of $500,000.

(5)

Mr. King joined MRV in January 2008 as VP, Finance and Chief Compliance Officer, and was promoted to CFO in July 2009.

(6)

Mr. Gorsun was hired in October 2010 and has a base salary of $230,000 per year.

(7)

Ms. Painter joined MRV in February 2009 as VP, General Counsel, added the Chief Compliance Officer role in July 2009, and became the Company's Secretary in November 2009.

(8)

Ms. Tuller was hired as the Director of Finance in January 2009 and was promoted to the position of VP, Finance in July 2009.

Grants of Plan-Based Awards in 2010

        The following table summarizes awards to Named Executive Officers during 2010:

---

(1)

Each of these awards were pursuant to the Company's Incentive Compensation Plan, and were paid out in March 2011.

(2)

Each of these non-qualified stock option awards was granted under the 2007 Plan and vests pro rata over four years in annual increments from the date of grant, provided the executive officer is employed by the Company on such vesting dates, with the exception of Mr. Singh's grant which vests in full on July 1, 2011 and was not granted under the 2007 Plan.

(3)

The exercise price for the stock options granted was the closing price of our Common Stock as reported by the OTC Pink Sheets on the date of grant.

(4)

Dollar amounts reflect the value of the awards determined using the Black-Scholes model, which is the method we use to report the fair value for option awards in our financial statements in accordance with ASC 718, and do not reflect the actual value that may be realized upon exercise. The grant date fair value per option is $0.92 for the stock option grant on July l, 2010, $0.86 for the stock option grants on August 13, 2010, and $1.21 for the stock option grant on December 1, 2010. The assumptions used to calculate the value of the option awards are set forth under Note 13 (Share-Based Compensation) in the Notes to the financial statements included in our Original Filing.

Other Compensation Information

        There were no option exercises by Named Executive Officers during 2010. We did not grant to any Named Executive Officer, nor did any Named Executive Officer vest in, any stock appreciation rights, or similar instruments, restricted stock, restricted stock units, or similar instruments during 2010. We generally do not have pension or other retirement plans, except for a 401(k) savings plan under which we make employer contributions on behalf of U.S. employees and a pension plan for our Swiss and Taiwan subsidiaries, and we make contributions to a 401(k)-type insurance fund for our Israeli employees. We do not have any nonqualified defined contribution or other nonqualified deferred compensation plans that provide for the deferral of compensation on a basis that is not tax-qualified.

Employment Agreements and Change of Control Arrangements

        Singh Employment Agreement.    Mr. Singh entered into a one-year employment agreement on July 8, 2010 to be our CEO, from July 1, 2010 to June 30, 2011, unless earlier terminated or further extended. Pursuant to his employment agreement, Mr. Singh receives a base salary of $500,000, and as an inducement to his employment, he received a one-time stock option grant to purchase 1,750,000 shares of our Common Stock at an exercise price equal to the closing price of our Common Stock on the grant date, which was July 1, 2010. The stock option vests in full on June 30, 2011, provided that Mr. Singh is still employed by MRV on such date. The stock option will also become fully vested upon a "change of control" or the termination of his employment by MRV other than for "cause." If Mr. Singh is terminated prior to June 30, 2011 by MRV without cause or by Mr. Singh for "good reason," then MRV will pay him a lump sum equal to the greater of the remaining base salary he otherwise would have been entitled to through such date, or $125,000. As of this date, the amount he would receive is $125,000. The agreement also includes, among other things, confidentiality, non-solicitation and non-disparagement provisions.

        Mr. Singh's employment agreement states that a "change of control" shall occur if one of the events set forth in our 2007 Plan occurs, which are, in summary: (a) the acquisition by any individual, entity or group (other than by MRV or related parties), of a number of our voting securities in excess of 25% of our voting securities unless such acquisition has been approved by the Board; (b) any election has occurred of persons to the Board that causes two-thirds of the Board to consist of persons other than persons who were members of the Board on the effective date of the 2007 Plan and persons who were nominated for elections as members of the Board at a time when two-thirds of the Board consisted of persons who were members of the Board on the effective date of the 2007 Plan, provided, however, that any person nominated for election by a Board at least two-thirds of whom constituted persons described above or by persons who were themselves nominated by such Board shall, for this purpose, be deemed to have been nominated by a Board composed of persons described above; (c) a reorganization, merger or consolidation involving MRV; (d) a sale or other disposition of all or substantially all the assets of MRV; or (e) a complete liquidation or dissolution of MRV. In Mr. Singh's agreement, "cause" is defined as: (w) willful misconduct or gross negligence which, in the good faith judgment of the Board of Directors, has a material adverse impact on MRV (either economically or on its reputation); (x) conviction of, or pleading of guilty or nolo contendere to, a felony (or equivalent outside of the United States) or any crime involving fraud or material dishonesty; (y) failure to attempt in good faith to perform his duties or to follow the legal direction of the Board, which failure is not remedied within 30 days of written notice from the Board specifying the details of the failure; and (z) any other material breach by Mr. Singh of his employment agreement, MRV's written code of conduct, written code of ethics or other written policy that is not remedied within 30 days of written notice from the Board specifying the details of such breach. "Good reason" is defined as, without Mr. Singh's prior consent: (i) a material diminution of his duties or responsibilities; (ii) a material diminution in Mr. Singh's base salary; or (iii) any material breach by MRV of a material provision of the employment agreement, subject to notice and cure provisions.

        Lotan Severance Agreement.    We entered into a Separation and Release Agreement with Mr. Lotan, our prior CEO, on June 8, 2010 which governed the terms of his separation from service with MRV and his resignation from the Board of MRV and from all other positions arising from or relating to his employment effective as of June 30, 2010. Mr. Lotan's separation agreement provided for a severance payment in two installments aggregating $633,528, with $548,538 payable on July 30, 2010, and the remaining $85,000 payable on January 2, 2011. In addition, Mr. Lotan is entitled to continued participation in the medical, dental and vision plans maintained by MRV for a period of up to 18 months subject to compliance with the Consolidated Budget Omnibus Reconciliation Act of 1985, as amended ("COBRA"), and payment of an amount equal to the employer portion of COBRA premium costs for the six-month period following such 18-month period; outplacement services for a period of six months up to a maximum cost of $7,500; a lump sum cash payment on July 30, 2010 equal to any unreimbursed business and entertainment expenses incurred prior to June 8, 2010 and accrued but unused vacation time; and pro-rated vesting of an outstanding stock option to purchase 100,000 shares of the Company's Common Stock, which resulted in the stock option being vested and exercisable with respect to 76,767 shares. All vested stock options held by Mr. Lotan remain exercisable for a period of three years (i.e., until June 30, 2013), but not beyond the stated term of the applicable stock option. All other stock options he held that were not vested as of June 30, 2010 were forfeited. In addition, Mr. Lotan retains the protection of the indemnification provisions under our by-laws as well as the right to coverage under any directors' and officers' liability insurance in the same amount and to the same extent that coverage is provided MRV's officers and directors. The separation agreement contained a mutual general release of claims (subject to certain exclusions) and a mutual non-disparagement covenant. Mr. Lotan further agreed to continue to be bound by limitations on post-employment activities and by customary covenants relating to the non-solicitation of employees and business partners that apply for a period of two years, as well as customary confidentiality and cooperation covenants.

        Gorsun Executive Agreement.    Mr. Gorsun entered into an executive agreement with our Optical Communications Systems ("OCS") subsidiary, MRV Communications — Boston Division, Inc. ("MRV Boston") in March 2011 that provides for the compensation, severance and other terms of employment for Mr. Gorsun, our OCS division president. The Executive Agreement provides for a base salary of $230,000, a target cash incentive bonus of 45% of his base salary for 2011 pursuant to the Company's Incentive Compensation Plan, and standard benefits as provided to similarly situated executives. Mr. Gorsun will receive a lump sum payment equal to six months base salary and payment of premiums of COBRA or its equivalent for 12 months upon termination by MRV Boston without "cause" or by him for "good reason." Further, if there is a "change of control" of MRV Boston, he will receive a lump sum payment equal to 12 months base salary and accelerated vesting of, and up to a three-year extended expiration period for, unvested equity grants. Upon his termination by MRV Boston without cause or by him for good reason in the 12-month period following a change of control of MRV Boston, he shall receive a lump sum payment equal to 12 months base salary and payment of premiums of COBRA or its equivalent for 12 months. The agreement includes, among other things, non-compete, non-solicitation and non-disparagement provisions.

        In Mr. Gorsun's agreement, "cause" is determined by MRV and defined as his (a) willful failure to perform the material duties of his position after receiving written notice of such failure and being given reasonable opportunity to cure such failure; (b) willful misconduct injurious to MRV Boston; or (c) conviction of, or plea of nolo contendere to, a felony or any other crime involving moral turpitude; subject to a good faith provision. "Good reason" is defined as: (x) a material diminution in Mr. Gorsun's duties or responsibilities; (y) a reduction in his base salary by greater than 15%; or (z) in any year a reduction in the target ratio of his annual short-term incentive compensation, bonus or other such payments to base compensation greater than 15%; or a change in the method of calculation of his annual short-term incentive compensation, bonus or other such payments that results in a reduction of this target annual short-term incentive compensation, bonus or other such payments to base compensation greater than 15%, unless such reductions are due to an increase in base compensation

(subject to notice and cure provisions). A "change of control" is defined as: (i) the acquisition by any person, other than MRV Boston or other related entities, of beneficial ownership of 50% or more of the combined voting power of MRV Boston's then outstanding voting securities; (ii) the purchase of a majority of the shares of common stock of MRV Boston under a tender or exchange offer, other than an offer by MRV Boston or other related entities; or (iii) completion of an merger, liquidation or dissolution of MRV Boston, or the sale of all or substantially all of its assets, in each case that does not result in MRV retaining direct or indirect control of the entity.

        Executive Severance Agreements.    In May 2010, Mr. King and Mmes. Painter and Tuller entered into executive severance agreements with us that provide for their continued dedication, loyalty and service. The severance agreements provide for a lump sum payment equal to one year base salary upon termination by MRV without "cause" or by the executive for "good reason," and payment of a pro-rated bonus based on the number of months worked in the year of separation and continuation of benefits for one year. The agreements also include, among other things, confidentiality, non-complete and non-solicitation provisions.

        "Cause" and "good reason" have the same definitions as in Mr. Gorsun's executive agreement, with the exceptions that: (a) references to MRV Boston in Mr. Gorsun's agreement are to MRV in the severance agreements; and (b) the severance agreements' "good reason" definition includes a requirement by MRV that the executives, without their consent, be based at a location more than 50 miles from their principal work location on the date of the request.

        King and Tuller Employment Agreements.    In addition to the executive severance agreements, Mr. King, our CFO, and Ms. Tuller, our VP, Finance, entered into standard employment agreements with us in July 2009 and December 2008, respectively, that set forth their title at that time, duties, compensation, and other standard terms.

Potential Payments upon Termination or Change of Control

        Singh Employment Agreement.    In accordance with Mr. Singh's employment agreement, he will receive a lump sum equal to the greater of the remaining base salary he otherwise would have been entitled to through June 30, 2011, or $125,000 if he is terminated prior to June 30, 2011 by MRV without cause or by Mr. Singh for good reason. As of this date, the amount he would receive is $125,000. In addition, his stock option will become fully vested upon a "change of control" or the termination of his employment by MRV other than for "cause" if he is terminated prior to June 30, 2011.

        Termination of Employment without Cause or for Good Reason (as of December 31, 2010)

        Executive Severance Agreements.    In accordance with the severance agreements for Mr. King and Mmes. Painter and Tuller, each of them would receive a lump sum payment equal to one year base salary upon their termination by MRV without cause or by the executive for good reason, payment of a pro-rated bonus based on the number of months worked in the year of separation, and continuation of benefits for one year. They do not receive any special benefits or compensation upon a change of control other than the acceleration of stock options which all employees receive.

Compensation of Non-Employee Directors

        Our compensation program for non-employee directors is designed to achieve the following goals: compensation should fairly pay directors for work required for a company of MRV's size and scope; compensation should align directors' interests with the long-term interest of our stockholders; and the structure of the compensation should be simple, transparent and easy to understand. In November 2009, the Board of Directors approved a change in the structure of its compensation plan, and revised it again in November 2010.

        Cash Compensation.    In November 2009, the Board of Directors approved a cash compensation arrangement in which each non-employee director was entitled to an annual cash retainer fee of $40,000, with no per meeting fees. Members of the Audit Committee received an additional $3,000 annual cash retainer fee and the members of the Compensation and Nomination and Governance Committees receive an additional $2,500 annual cash retainer fee. The Chair of the Audit Committee received an additional $5,000 annual cash retainer, the Chairs of the Compensation and Nomination and Governance Committees received an additional $4,000 annual cash retainer, and the Chair of the Board of Directors received an additional $60,000 annual cash retainer. The Chair of the Board also received an annual fee for the Chair of the Board equal to her Chair fee in order to compensate her for the extraordinary efforts that she was expected to contribute in her initial 12-month term. The cash retainer fees are paid in quarterly installments, and are prorated as appropriate based upon the dates and capacities in which each individual non-employee director served.

        In November 2010, the Board of Directors approved a revised compensation arrangement for non-employee directors. The annual cash retainer fee for all non-employee directors was increased to $42,000, with no per meeting fees. All non-Chair committee members receive an additional $4,000 cash retainer fee per committee, while the Chairs of the committees receive the following additional cash retainer fees: Audit Committee Chair, $10,000; Compensation Committee Chair, $7,000; and Nomination and Governance Committee Chair, $6,000. The Chair of the Board receives an additional cash retainer fee of $100,000 for his services, and this fee was made retroactive to August 24, 2010, which was the date Dr. Shubin Stein became Chairman of the Board. The cash retainer fees were paid in quarterly installments, and were prorated as appropriate based upon the dates and capacities in which each individual non-employee director serves.

        Equity Compensation.    The compensation arrangement for non-employee directors approved in November 2009 included automatic annual grants of stock options and restricted stock. Under the arrangement, each non-employee director was granted an option to purchase 20,000 shares of Common Stock, at an exercise price equal to the closing price of Common Stock on the date of grant, which is the same date as the annual grant to employees. These options vest over four years pro rata in annual installments beginning on the first anniversary of the date of grant, however, the options will vest in full on an accelerated basis upon a change of control (as defined in our 2007 Omnibus Incentive Plan). On the same grant date, each non-employee director was granted 10,000 shares of restricted stock, which vest upon the earlier of one year from date of grant or a change of control. The Chair of the Board of Directors was granted an additional 18,000 shares of restricted stock and 36,000 stock options. No stock options or restricted stock were granted to directors in 2009.

        In November 2009, the Board further noted that certain directors had promised our stockholders that they would not take cash compensation or restricted stock if elected to the Board. Therefore, the Board provided all of its directors the ability to elect to receive stock options in lieu of payment of the cash compensation or restricted stock grants described above. The equivalent stock options are valued pursuant to the Black-Scholes valuation method, and are granted on the same date as the annual grant of stock options to Board members. In November 2010, the Board approved that the stock option grants in lieu of payment for cash compensation are to be granted annually in advance.

        In November 2010, the Board approved a revised equity compensation arrangement for non-employee directors, in which they receive an equivalent of $50,000 of equity each year, which amount they can elect to receive in stock options or restricted stock, with a maximum of 50% election in restricted stock. The number of shares to be received in stock options is determined by using the Black-Scholes valuation method, the number of shares of restricted stock is determined by using the closing price of MRV's Common Stock on the valuation date, and the valuation date is set at three business days prior to the grant date. The stock options and restricted stock each vest in full upon the earlier of one year from date of grant or a change of control. The stock options have an exercise price equal to the closing price of the Company's Common Stock on the date of grant. Due to the change in the non-employee

directors equity compensation, a make-up equity grant was awarded to the directors on December 1, 2010 pro rated to provide additional equity for their services through May 31, 2011. This special make-up grant had reduced vesting terms since the grants were for services that would be completed in six months, and the vesting schedules for the restricted stock and stock option grants were accordingly reduced to six months. All other terms remained the same.

        Due to the approval of a new compensation arrangement for the directors, Board members received two equity grants during 2010. The annual grant date occurred on August 13, 2010, and the Black-Scholes valuation used to convert cash to stock options for the directors who elected such was $1.24 per share. Upon revision of the non-employee directors compensation arrangement in November 2010, a make-up equity grant was awarded to the directors on December 1, 2010 pro rated to provide additional equity for their services through May 31, 2011. The Black-Scholes valuation of a stock option for the second grant was $1.15 per share, and this valuation was used to convert cash into an equivalent number of stock options for those directors who elected not to receive cash compensation and to determine the number of options to be granted on the second grant date of December 1, 2010.

Item 12.    Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

        The following table sets forth information with respect to each holder known to MRV to be the beneficial owner of 5% or more of the outstanding shares of Common Stock as of March 31, 2011.

Beneficial Ownership of Common Stock by Directors
and Named Executive Officers and Adoption of Stock Ownership Guidelines

        We encourage our directors, officers and employees to own our Common Stock, as we believe that owning Common Stock aligns their interest with the interests of our stockholders. In addition, the Board of Directors approved a framework for stock ownership guidelines at its March 9, 2011 meeting. The approved framework will require directors to hold equity in MRV with a value equal to three times their annual retainer prior to being able to sell shares issued upon exercise of stock options, restricted shares or other equity grants received after the date of implementation of the policy. Our CEO will be required to hold equity in MRV with a value equal to five times his annual base salary, executive vice presidents and above (including the CFO and presidents of our divisions) will be required to hold three times their

annual base salaries, and senior vice presidents and vice presidents will be required to hold equity with a value equal to two times their annual base salaries, prior to being able to sell shares issued upon exercise of stock options, restricted shares or other equity grants received after the date of implementation of the policy. When the directors and officers obtain the threshold stock ownership amounts, they may sell up to 40% of their shares issued upon exercise of stock options, restricted shares and other equity grants received after the date of implementation of the policy. The policy will also include a hardship provision for appropriate circumstances. The following table summarizes the number of shares of Common Stock beneficially owned by our Named Executive Officers, by our directors and by our directors and executive officers as a group as of March 31, 2011. This table is based on information provided by our officers and directors.

Item 14.    Principal Accountant Fees and Services.

        The Audit Committee's policy and procedure is to pre-approve all audit and permissible non-audit related services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and generally subject to a specific budget. The policy authorizes the Audit Committee to delegate to one or more of its members pre-approval authority with respect to permitted services.

        The independent registered public accounting firm and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed through the date of the auditor's periodic report. The Audit Committee may also pre-approve particular services on a case-by-case basis. The Audit Committee approved 100% of the professional services for the Audit, Audit-Related, Tax and Other Fees indicated below for the years ended December 31, 2010 and 2009.
