Prior to the completion of our IPO, we adopted the 2012 Plan. The purposes of the 2012 Plan are to provide additional incentives to our management, employees, directors, independent contractors and consultants, to strengthen their commitment, motivate them to faithfully and diligently perform their responsibilities and to attract and retain competent and dedicated persons whose contributions are essential to the success of our business and whose efforts will impact our long-term growth and profitability. To accomplish such purposes, the 2012 Plan provides for the issuance of stock options, share appreciation rights, restricted shares, restricted stock units, performance shares and other share-based awards, which we refer to as plan awards.

We reserved a total of 1,250,000 shares of common stock that are available for issuance under the 2012 Plan. The maximum aggregate awards that may be granted during any fiscal year to any individual will be 200,000 shares, and in the case of options to acquire shares, with a per share exercise price equal to the grant date fair market value of a share. If the shares underlying any plan award are forfeited, cancelled,canceled, exchanged or surrendered or if a plan award otherwise terminates or expires without a distribution of shares, the shares will again become available under the 2012 Plan provided that shares surrendered or withheld as payment of either the exercise price of an award (including shares otherwise underlying an award of a share appreciation right that are retained by us to account for the grant price of such share appreciation right) and/or withholding taxes in respect of an award will no longer be available for grant under the 2012 Plan, and notwithstanding that a share appreciation right is settled by the delivery of a net number of shares of the full number of shares underlying such share appreciation right will not be available for subsequent awards under the 2012 Plan. In addition, awards are paid or settled in cash, the number of shares with respect to which such payment or settlement is made will again be available for grants of awards under the 2012 Plan and shares underlying awards that can only be settled in cash will not be counted against the aggregate number of shares available for awards under the 2012 Plan.

The 2012 Plan is administered by our compensation committee (the "Plan Administrator"). The Plan Administrator may construe and interpret the 2012 Plan and may adopt, alter and repeal rules and make all other determinations necessary or desirable to administer the 2012 Plan.

The Plan Administrator may select the employees, directors, independent contractors and consultants who will receive plan awards, determine the terms and conditions of those awards, including but not limited to the exercise price, the number of shares of common stock subject to awards, the term of the awards, and the vesting schedule applicable to awards. Unless otherwise determined by the Plan Administrator, all awards that vest solely on a requirement of continued employment or service may not become fully vested prior to the second anniversary of the date upon which the award is granted.

We may issue stock options under the 2012 Plan. All stock options granted under the 2012 Plan are intended to be non-qualified stock options and are not intended to qualify as incentive stock options within the meaning of Section 422 of the Code. The option exercise price of all stock options granted under the 2012 Plan will be determined by the Plan Administrator, but in no event will the exercise price be less than 100% of the fair market value of the common stock on the date of grant. The term of all stock options granted under the 2012 Plan will be determined by the Plan Administrator, but may not exceed ten years from the date of grant. Each stock option will be exercisable at such time and subject to such terms and conditions as determined by the Plan Administrator in the applicable stock option agreement. Other than equitable adjustments made in connection to a change in capitalization, under no circumstances will an exercise price be reduced following the date of the grant of an option, nor will an option be cancelled in exchange for a replacement option with a lower exercise price without stockholder approval.

Unless the applicable stock option agreement provides otherwise, in the event of an optionee’s termination of employment or service for any reason other than for cause, disability or death, such optionee’s stock options (to the extent exercisable at the time of such termination) generally will remain exercisable until 30 days after such termination and then expire. Unless the applicable stock option agreement provides otherwise, in the event of an optionee’s termination of employment or service due to, disability or death, such optionee’s stock options (to the extent exercisable at the time of such termination) generally will remain exercisable until one year after such termination and will then expire. For certain employees, a demotion in position will result in a loss of unvested options. If termination was for any other reason other than for cause, stock options that were not exercisable on the date of termination will expire at the close of business on the date of such termination. In the event of an optionee’s termination of employment or service for cause, such optionee’s outstanding stock options will expire at the commencement of business on the date of such termination. The Plan Administrator may waive the vesting requirements based on such factors as the Plan Administrator deems appropriate.

Share appreciation rights (“SARs”) may be granted under the 2012 Plan either alone or in conjunction with all or part of any stock option granted under the 2012 Plan. A free-standing SAR granted under the 2012 Plan entitles its holder to receive, at the time of exercise, the number of shares, or alternate form of payment determined by the Plan Administrator, equal in value to the excess of the fair market value (at the date of exercise) over a specified price fixed by the Plan Administrator (which shall be no less than fair market value at the date of grant). A SAR granted in conjunction with all or part of an option under the 2012 Plan entitles its holder to receive, upon surrendering of the related option, the number of shares, or alternate form of payment determined by the Plan Administrator, equal in value to the excess of the fair market value (at the date of exercise) over the exercise price of the

related stock option. The term of all SARs granted under the 2012 Plan will be determined by the Plan Administrator, but may not exceed ten years from the date of grant. In the event of a participant’s termination of employment or service, free-standing SARs will be exercisable at such times and subject to such terms and conditions determined by the Plan Administrator, while SARs granted in conjunction with all or part of an option will be exercisable at such times and subject to terms and conditions applicable to the related option. Other than equitable adjustments made in connection to a change in capitalization, under no circumstances will an exercise price be reduced following the date of the grant of a SAR, nor will a SAR be cancelled in exchange for a replacement SAR with a lower exercise price without stockholder approval.

Restricted shares, restricted stock units and performance shares may be granted under the 2012 Plan. The Plan Administrator will determine the number of shares to be awarded, the purchase price, vesting schedule and performance objectives, if any, applicable to the grant of restricted shares, restricted stock units and performance shares. Participants with restricted shares and performance shares generally have all of the rights of a stockholder and restricted stock units generally do not have the rights of a stockholder. However, during the restricted period, restricted stock units may be paid dividends on the number of shares covered by the restricted stock units if the applicable award agreement so provides. If the performance goals and other restrictions are not satisfied, the restricted shares, restricted stock units and/or performance shares will be forfeited in accordance with the terms of the grant. Subject to the provisions of the 2012 Plan and applicable award agreement, the Plan Administrator has sole discretion to provide for the lapse of restrictions in installments or the acceleration or waiver of restrictions (in whole or part) under certain circumstances, based upon such factors including, but not limited to, the attainment of certain performance goals, a participant’s termination of employment or service or a participant’s death or disability.

The 2012 Plan also authorizes grants of other share-based awards, such as unrestricted shares, restricted stock units, dividend equivalents or performance units. The Plan Administrator will determine the terms and conditions of such awards, consistent with the terms of the 2012 Plan, at the date of grant or thereafter, including any performance goals and performance periods.

In the case of awards subject to performance goals, such goal may be based on one or more of the following criteria: (i)(a) earnings, including one or more of operating income, earnings before or after taxes, earnings before or after interest, depreciation, amortization, adjusted EBITDA, economic earnings, or extraordinary or special items or book value per share (which may exclude nonrecurring items); (ii)(b) pre-tax income or after-tax income; (iii)(c) earnings per share (basic or diluted); (iv)(d) operating profit; (v)(e) revenue, revenue growth or rate of revenue growth; (vi)(f) return on assets (gross or net), return on investment, return on capital, or return on equity; (vii)(g) returns on sales or revenues; (viii)(h) operating expenses; (ix)(i) share price appreciation; (x)(j) cash flow, free cash flow, cash flow return on investment (discounted or otherwise), net cash provided by operations, or cash flow in excess of cost of capital; (xi)(k) implementation or completion of critical projects or processes; (xii)(l) cumulative earnings per share growth; (xiii)(m) operating margin or profit margin; (xiv)(n) cost targets, reductions and savings, productivity and efficiencies; (xv)(o) strategic business criteria, consisting of one or more objectives based on meeting specified market penetration, geographic business expansion, customer satisfaction, employee satisfaction, human resources management, supervision of litigation, information technology, and goals relating to acquisitions, divestitures, joint ventures and similar transactions, and budget comparisons; (xvi)(p) personal professional objectives, including any of the foregoing performance goals, the implementation of policies and plans, the negotiation of transactions, the development of long term business goals, formation of joint ventures, research or development collaborations, and the completion of other corporate transactions; and (xvii)(q) any combination of, or a specified increase in, any of the foregoing. Where applicable, a performance goal may be expressed in terms of attaining a specified level of the particular criteria or the attainment of a percentage increase or decrease in the particular criteria, and may be applied to one or more of the company or a company affiliate, or a division or strategic business unit of the company, or may be applied to the performance of the company relative to a market index, a group of other companies or a combination thereof, all as determined by the Administrator. The performance goals may include a threshold level of performance below which no payment may be made (or no vesting may occur), levels of performance at which specified payments may be made (or specified vesting may occur), and a maximum level of performance above which no additional payment shall be made (or at which full vesting may occur). Each of the foregoing performance goals will determine in accordance with generally accepted accounting principles, as applicable, and may be subject to certification by the committee; provided, that the committee shall have the authority to make equitable adjustments to the performance goals, to the extent permitted under Section 162(m) of the Code, if applicable, in recognition of unusual or non-recurring events affecting the company or any company affiliate thereof or the financial statements of the company or any company affiliate thereof, in response to changes in applicable laws or regulations, or to account for items of gain, loss or expense determined to be extraordinary or unusual in nature or infrequent in occurrence or related to the disposal of a segment of a business or related to a change in accounting principles.

In the event of a merger, amalgamation, consolidation, recapitalization, reorganization, stock dividend, stock split or other change in corporate structure affecting the common stock, an equitable substitution or proportionate adjustment shall be made, as may be determined by the Plan Administrator, in (a) the aggregate number of shares of common stock reserved for issuance under the 2012 Plan and the maximum number of shares of common stock that may be subject to awards granted to any participant in any calendar year, (b) the kind, number and exercise price subject to outstanding stock options and SARs granted under the 2012 Plan, and (c) the kind, number and purchase price of shares of common stock subject to outstanding awards of restricted shares, restricted stock units, performance shares or other share-based awards granted under the 2012 Plan. In addition, the Plan Administrator, in

its discretion, may terminate all outstanding awards for the payment of cash or in-kind consideration. However, no adjustment or payment may cause any award under the 2012 Plan that is or becomes subject to Section 409A of the Code to fail to comply with the requirements of that section.

Unless otherwise determined by the Plan Administrator and evidenced in an award agreement, in the event that a change in control occurs and a participant’s employment or service is terminated without cause on or after the effective date of the change in control but prior to 24 months following the change in control, then any unvested or unexercisable portion of any award carrying a right to exercise shall become fully vested and exercisable, and the restrictions, deferral limitations, payment conditions and forfeiture

Until such time as the awards are fully vested and/or exercisable in accordance with the 2012 Plan, awards may not be sold, assigned, mortgaged, hypothecated, transferred, charged, pledged, encumbrance, gifted, transferred in trust (voting or other) or disposed in any other manner, except with the prior written consent of the administrator, which consent may be granted or withheld in the sole discretion of the Plan Administrator.

The 2012 Plan provides our board of directors with authority to suspend or terminate the 2012 Plan or any award, or revise and amend the 2012 Plan. However, stockholder approval is required for any amendment to the extent it is required to comply with applicable law or stock exchange listing requirements. The 2012 Plan will automatically terminate on the tenth anniversary of the effective date (although awards granted before that time will remain outstanding in accordance with their terms).

The award agreements for the 2012 Plan provide the board of directors and the Plan Administrator with the sole discretion to cancel or require repayments of awards in the event an award recipient engages in certain conduct deemed harmful to the Company.

In connection with the adoption of the 2012 Plan the board of directors terminated the 2006 Stock Option Plan (the "2006 Plan") effective as of July 27, 2012, and no further awards may be granted under the 2006 Plan after such date. However, the termination of the 2006 Plan did not affect awards outstanding under the 2006 Plan at the time of its termination and the terms of the 2006 Plan continue to govern outstanding awards granted under the 2006 Plan. The options granted under the 2006 Plan expire 10 years after the date of grant. Subject to the grantee’s continued employment with us, allThe outstanding options granted under the plan generally vest 20% on each2006 Plan were fully vested as of the first five anniversaries of the date of grant.December 31, 2017.
