AMENDED AND RESTATED

EMPLOYMENT AGREEMENT

 

This AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the “Agreement”) is made February 29, 2012 by and between Supernus Pharmaceuticals, Inc., a Delaware corporation (the “Employer”), and Jack Khattar (the “Executive”).  In consideration of the mutual covenants contained in this Agreement, the Employer and the Executive agree as follows:

 

WHEREAS the Executive and the Employer originally entered into an employment agreement dated December 22, 2005; and

 

WHEREAS the Executive and the Employer have agreed to execute the Agreement to govern their relationship effective as of January 1, 2012 (the “Effective Date”).

 

NOW THEREFORE, in consideration of the foregoing premises and other consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be bound hereby, agree as follows:

 

1.                                      Employment.  The Employer agrees to employ the Executive and the Executive agrees to be employed by the Employer on the terms and conditions set forth in this Agreement.

 

2.                                      Capacity.  The Executive shall continue to serve the Employer as President and Chief Executive Officer.  The Executive shall also serve the Employer in such other or additional offices as the Executive may be requested to serve by the Board of Directors of the Employer (the “Board of Directors”), provided that (a) such other offices are commensurate with the Executive’s background and skills and his position as a Member of the Board and (b) the Executive reports directly to the Board of Directors in such other offices.  In such capacity or capacities, the Executive shall perform such services and duties in connection with the business, affairs and operations of the Employer as may be assigned or delegated to the Executive from time to time by or under the authority of the Board of Directors.

 

3.                                      At-Will Employment.  The Employer and the Executive agree and acknowledge that the Executive’s employment is at-will and may be terminated by either party at any time for any or no reason.

 

4.                                      Compensation and Benefits.  The regular compensation and benefits payable to the Executive under this Agreement shall be as follows:

 

(a)                                 Salary.  For all services rendered by the Executive under this Agreement, the Employer shall pay the Executive a salary (the “Salary”) at the annual rate of Four Hundred Thirty-Two Thousand Seven Hundred Eighty-Six Dollars ($432,786), subject to increase from time to time in the discretion of the Board of Directors or the Compensation Committee of the Board of Directors (the “Compensation Committee”).  The Salary shall be payable in periodic installments in accordance with the Employer’s usual practice for its senior executives.

 

(b)                                 Bonus.  The Executive shall be entitled to participate in an annual bonus program established by the Board of Directors or the Compensation Committee with such terms as may be established in the sole discretion of the Board of Directors or Compensation

 











 

Committee, provided that the gross amount of such annual bonus paid to the Executive, if any, shall not exceed forty percent (40%) of the Executive’s Salary for that calendar year.

 

(c)                                  Regular Benefits.  The Executive shall also be entitled to participate in any employee benefit plans, incentive plans, medical insurance plans, life insurance plans, disability income plans, retirement plans, vacation plans, expense reimbursement plans and other benefit plans which the Employer may from time to time have in effect for employees at or above the level of Executive Vice President, as well as any benefits that may be made available to all or a majority of lower- level senior executives.  Such participation shall be subject to the terms of the applicable plan documents, generally applicable policies of the Employer, applicable law and the discretion of the Board of Directors, the Compensation Committee or any administrative or other committee provided for in or contemplated by any such plan.  Nothing contained in this Agreement shall be construed to create any obligation on the part of the Employer to establish any such plan or to maintain the effectiveness of any such plan which may be in effect from time to time.

 

(d)                                 Vacation.  The Executive is entitled to paid vacation of twenty (20) days per year, or such greater number as may be provided in Employer’s policy for senior executives, in addition to all holidays provided in such policies.  The amount of accrued but unused vacation time payable to the Executive upon termination of the Executive’s employment shall be calculated pro rata based on the number of months the Executive worked in the year of termination, reduced by the number of vacation days taken by the Executive in the year of termination.

 

(e)                                  Taxation of Payments and Benefits.  All payments made by the Employer under this Agreement shall be reduced by any tax or other amounts required to be withheld by the Employer under applicable law.  Nothing in this Agreement shall be construed to require the Employer to make any payments to compensate the Executive for any adverse tax effect associated with any payments or benefits or for any deduction or withholding from any payment or benefit.

 

(f)                                   Exclusivity of Salary and Benefits.  The Executive shall not be entitled to any payments or benefits other than those provided under this Agreement.

 

5.                                      Extent of Service.  During the Executive’s employment under this Agreement, the Executive shall, subject to the direction and supervision of the Board of Directors, devote the Executive’s full business time, best efforts and business judgment, skill and knowledge to the advancement of the Employer’s interests and to the discharge of the Executive’s duties and responsibilities under this Agreement.  The Executive shall not engage in any other business activity, except as may be approved by the Board of Directors; provided that nothing in this Agreement shall be construed as preventing the Executive from:

 

(a)                                 investing the Executive’s assets in any company or other entity in a manner not prohibited by Section 7(d) and in such form or manner as shall not require any material activities on the Executive’s part in connection with the operations or affairs of the companies or other entities in which such investments are made; or

 

2











 

(b)                                 engaging in religious, charitable or other community or non-profit activities that do not impair the Executive’s ability to fulfill the Executive’s duties and responsibilities under this Agreement.

 

6.                                      Termination Benefits.  Unless otherwise specifically provided in this Agreement or otherwise required by law, all compensation and benefits payable to the Executive under this Agreement shall terminate on the date of termination of the Executive’s employment.

 

(a)                                 Termination Benefits.  Notwithstanding the provisions of Section 3, if the Executive’s employment is terminated by the Executive for Good Reason, or by the Executive for Good Reason after a Change of Control, or by the Employer without Cause, the Employer shall provide to the Executive the following termination benefits (“Termination Benefits”), subject to the Executive’s execution of a release of any and all legal claims in a form satisfactory to the Employer no later than 45 days following the date of such termination and subject to the Executive not revoking such release:

 

(i)                                     payments, made in substantially equal periodic installments until the date that is eighteen months following such date of termination on the Employer’s regular payroll dates for its senior executives, the sum of which is equivalent to the sum of (A) eighteen (18) months of the Executive’s Salary at the rate in effect as of the date of termination pursuant to Section 4(a), and (B) the most recent bonus paid to the Executive by the Employer pursuant to Section 4(b); and

 

(ii)                                  a monthly payment made on the Employer’s first regular payroll date of each month during the installment period described in Section 6(a)(i) above equal on an after-tax basis (as determined on an estimated basis by the Company using such reasonable assumptions as the Company shall determine in its discretion) to the monthly amount that the Company was paying for the Executive and his family’s medical and dental coverage as in effect immediately prior to termination;

 

provided, that Termination Benefits shall first become payable on the first regular payroll date for senior executives that is at least 60 days after the date of termination and that the first payment of Termination Benefits shall include such amounts as would have been paid to the Executive had such payments begun with the first payroll date for senior executives following the date of termination.

 

(b)                                 Taxes.  Anything in this Agreement to the contrary notwithstanding, in the event that any payment or distribution by the Employer to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, including but not limited to the Termination Benefits (the “CIC Payments”), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), the following provisions shall apply:

 

(A)                               If the CIC Payments, reduced by the sum of (1) the Excise Tax and (2) the total of the federal, state, and local income and employment taxes payable by the Executive on the amount of the CIC Payments which are in excess of the

 

3











 

Threshold Amount, are greater than or equal to the Threshold Amount, the Executive shall be entitled to the full benefits payable under this Agreement; or

 

(B)                               If the Threshold Amount is less than (x) the CIC Payments, but greater than (y) the CIC Payments reduced by the sum of (1) the Excise Tax and (2) the total of the federal, state, and local income and employment taxes payable by the Executive on the amount of the CIC Payments which are in excess of the Threshold Amount, then the benefits payable under this Agreement shall be reduced (but not below zero) to the extent necessary so that the maximum CIC Payments shall not exceed the Threshold Amount.  To the extent that there is more than one method of reducing the CIC Payments to bring them within the Threshold Amount, the CIC Payments shall be reduced to the Threshold Amount in the following order: (i) first, by reducing the Termination Benefits to the extent necessary, (ii) second, if necessary, by reducing CIC Payments other than Termination Benefits that are not subject to the rule described in Treasury Regulation Section 1.280G-1 Q&A 24(c), and (iii) third, if necessary, by reducing CIC Payments other than Termination Benefits that are subject to the rule described in Treasury Regulation Section 1.280G-1 Q&A 24(c); provided, however, that in each case where amounts are paid in more than one installment, each installment shall be reduced proportionally; and provided, further, that in each case payments are reduced starting with any cash payments that shall be exempt from Section 409A and proceeding to other payments that are not exempt from Section 409A.

 

For the purposes of this Section 6(b), “Threshold Amount” shall mean three times the Executive’s “base amount” within the meaning of Section 280G(b)(3) of the Code and the regulations promulgated thereunder less one dollar ($1.00); and “Excise Tax” shall mean the excise tax imposed by Section 4999 of the Code.

 

The determination as to which of the alternative provisions set forth above shall apply to the Executive shall be made by a nationally recognized accounting firm selected by the Employer (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Employer and the Executive within 15 business days of the date of termination of the Executive’s employment, if applicable, or at such earlier time as is reasonably requested by the Employer or the Executive.  For purposes of determining which of the alternative provisions set forth above shall apply, the Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in the state and locality of the Executive’s residence on the date of termination of the Executive’s employment, net of the maximum reduction in Federal income taxes which could be obtained from deduction of such state and local taxes.  Any determination by the Accounting Firm shall be binding upon the Employer and the Executive.

 

(c)                                  Cause.  Only the following shall constitute “Cause” for purposes of this Agreement:

 

4











 

(i)                                     the commission by the Executive of criminal acts involving moral turpitude, deceit, dishonesty or fraud;

 

(ii)                                  gross negligence, willful misconduct or insubordination of the Executive with respect to the Employer or any affiliate of the Employer;

 

(iii)                               material breach by the Executive of any of the Executive’s obligations under this Agreement or under any other agreement the Executive has entered into with the Employer; or

 

(iv)                              the inability of the Executive to perform the Executive’s duties for a period of six (6) months or more as a result of a disability, provided that the Employer has a long-term disability insurance policy in place at such time which provides for payment of up to 60% of an eligible employee’s salary and the Executive qualifies for same.

 

If any question shall arise as to whether during any period the Executive is disabled so as to be unable to perform the Executive’s duties, the Executive may, and at the request of the Employer shall, submit to the Employer a certification in reasonable detail by a physician selected by the Employer to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue.  The Executive shall cooperate with any reasonable request of the physician in connection with such certification.  If such question shall arise and the Executive shall fail to submit such certification, the Employer’s determination of such issue shall be binding on the Executive.

 

(d)                                 Good Reason.  Only the following shall constitute “Good Reason” prior to a Change of Control for purposes of this Agreement:

 

(i)                                     a reduction of the Executive’s salary, other than a reduction that (1) is based on the Employer’s financial performance or (2) is similar to the reduction made to the salaries provided to all or most other senior executives of the Employer; or

 

(ii)                                  a significant change in the Executive’s responsibilities and/or duties which constitutes, when compared to the Executive’s previous responsibilities and/or duties, a demotion; or

 

(iii)                               the relocation of the offices at which the Executive is principally employed to a location more than fifty (50) miles from such offices, which relocation is not approved by the Executive.

 

The Executive shall provide the Employer with reasonable notice and an opportunity to cure any of the events listed in this Section 6(d) and shall not be entitled to compensation pursuant to this Section 6 unless the Employer fails to cure within a reasonable period.

 

(e)                                  Good Reason After Change of Control.  Only the following shall constitute “Good Reason” after a Change of Control for purposes of this Agreement:

 

5











 

(i)                                     a reduction of the Executive’s salary after a Change of Control; or

 

(ii)                                  a significant change in the Executive’s responsibilities and/or duties which constitutes, when compared to the Executive’s responsibilities and/or duties before the Change of Control, a demotion; or

 

(iii)                               the relocation of the offices at which the Executive is principally employed as of the Change of Control to a location more than fifty (50) miles from such offices, which relocation is not approved by the Executive.

 

The Executive shall provide the Employer with reasonable notice and an opportunity to cure any of the events listed in this Section 6(e) and shall not be entitled to compensation pursuant to this Section 6 unless the Employer fails to cure within a reasonable period.

 

(f)                                   Change of Control.  “Change of Control” shall mean the occurrence of one or more of the following events:

 

(i)                                     any “person” (as such term is used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) becomes a “beneficial owner” (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) (other than the Employer, any trustee or other fiduciary holding securities under an employee benefit plan of the Employer, or any corporation owned, directly or indirectly, by the stockholders of the Employer, in substantially the same proportions as their ownership of stock of the Employer), directly or indirectly, of securities of the Employer, representing fifty percent (50%) or more of the combined voting power of the Employer’s then outstanding securities; or

 

(ii)                                  persons who, as of the date of this Agreement, constituted the Employer’s Board of Directors (the “Incumbent Board”) cease for any reason including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board of Directors, provided that any person becoming a director of the Employer subsequent to the date of this Agreement whose election was approved by at least a majority of the directors comprising the Incumbent Board at the time of such approval shall, for purposes of this Agreement, be considered a member of the Incumbent Board; or

 

(iii)                               the stockholders of the Employer approve a merger or consolidation of the Employer with any other corporation or other entity, other than (1) a merger or consolidation which would result in the voting securities of the Employer outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the combined voting power of the voting securities of the Employer or such surviving entity outstanding immediately after such merger or consolidation or (2) a merger or consolidation effected to implement a recapitalization of the Employer (or similar transaction) in which no “person” (as hereinabove defined) acquires more than fifty percent (50%) of the combined voting power of the Employer’s then outstanding securities; or

 

6









 

(iv)          the stockholders of the Employer approve a plan of complete liquidation of the Employer or an agreement for the sale or disposition by the Employer of all or substantially all of the Employer’s assets.

 

7.             Confidential Information, Noncompetition and Cooperation.

 

(a)           Confidential Information.  As used in this Agreement, “Confidential Information” means information belonging to the Employer which is of value to the Employer in the course of conducting its business and the disclosure of which could result in a competitive or other disadvantage to the Employer.  Confidential Information includes, without limitation, financial information, reports, and forecasts; inventions, improvements and other intellectual property; trade secrets; know-how; designs, processes or formulae; software; market or sales information or plans; customer lists; and business plans, prospects and opportunities (such as possible acquisitions or dispositions of businesses or facilities) which have been discussed or considered by the management of the Employer.  Confidential Information includes information developed by the Executive in the course of the Executive’s employment by the Employer, as well as other information to which the Executive may have access in connection with the Executive’s employment.  Confidential Information also includes the confidential information of others with which the Employer has a business relationship.  Notwithstanding the foregoing, Confidential Information does not include information in the public domain, unless due to breach of the Executive’s duties under Section 7(b).

 

(b)           Confidentiality.  The Executive understands and agrees that the Executive’s employment creates a relationship of confidence and trust between the Executive and the Employer with respect to all Confidential Information.  At all times, both during the Executive’s employment with the Employer and after its termination, the Executive will keep in confidence and trust all such Confidential Information, and will not use or disclose any such Confidential Information without the written consent of the Employer, except as may be necessary in the ordinary course of performing the Executive’s duties to the Employer.

 

(c)           Documents, Records, etc.  All documents, records, data, apparatus, equipment and other physical property, whether or not pertaining to Confidential Information, which are furnished to the Executive by the Employer or are produced by the Executive in connection with the Executive’s employment will be and remain the sole property of the Employer.  The Executive will return to the Employer all such materials and property as and when requested by the Employer.  In any event, the Executive will return all such materials and property immediately upon termination of the Executive’s employment for any reason.  The Executive will not retain with the Executive any such material or property or any copies thereof after such termination.  The Executive will not retain with the Executive any such material or property or any copies thereof after such termination without the Employer’s knowledge and consent.  The Employer’s consent shall not be unreasonably withheld with regard to personnel information related exclusively to the Executive’s compensation or evaluations of the Executive’s performance.

 

(d)           Noncompetition and Nonsolicitation.  During the Executive’s employment with the Employer and for twelve (12) months thereafter (or during the Termination Benefits period, if longer), the Executive (i) will not, directly or indirectly, whether as owner, partner,

 

7











 

shareholder, consultant, agent, employee, co-venturer or otherwise, engage, participate, assist or invest in any Competing Business (as hereinafter defined); (ii) will refrain from directly or indirectly employing, attempting to employ, recruiting or otherwise soliciting, inducing or influencing any person to leave employment with the Employer (other than terminations of employment of subordinate employees undertaken in the course of the Executive’s employment with the Employer); and (iii) will refrain from soliciting or encouraging any customer or supplier to terminate or otherwise modify adversely its business relationship with the Employer.  The Executive understands that the restrictions set forth in this Section 7(d) are intended to protect the Employer’s interest in its Confidential Information and established employee, customer and supplier relationships and goodwill, and agrees that such restrictions are reasonable and appropriate for this purpose.  For purposes of this Agreement, the term “Competing Business” shall mean a business conducted anywhere in the world whose primary business is the development, manufacture or marketing of oral drug delivery technologies.  Notwithstanding the foregoing, the Executive may own up to one percent (1%) of the outstanding stock of a publicly held corporation which constitutes or is affiliated with a Competing Business.

 

(e)           Third-Party Agreements and Rights.  The Executive hereby confirms that the Executive is not bound by the terms of any agreement with any previous employer or other party which restricts in any way the Executive’s use or disclosure of information or the Executive’s engagement in any business.  The Executive represents to the Employer that the Executive’s execution of this Agreement, the Executive’s employment with the Employer and the performance of the Executive’s proposed duties for the Employer will not violate any obligations the Executive may have to any such previous employer or other party.  In the Executive’s work for the Employer, the Executive will not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other party, and the Executive will not bring to the premises of the Employer any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party.

 

(f)            Litigation and Regulatory Cooperation.  During and after the Executive’s employment, the Executive shall cooperate fully with the Employer in the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Employer which relate to events or occurrences that transpired while the Executive was employed by the Employer.  The Executive’s full cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Employer at mutually convenient times.  During and after the Executive’s employment, the Executive also shall cooperate fully with the Employer in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Employer.  The Employer shall reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this Section 7(f).  To the extent the Employer has control over scheduling, Employer shall use its best efforts to schedule all matters requiring the Executive’s participation at times that do not result in a financial burden to Executive or adversely impact his subsequent employment.

 

8











 

(g)           Injunction.  The Executive agrees that it would be difficult to measure any damages caused to the Employer which might result from any breach by the Executive of the promises set forth in this Section 7, and that in any event money damages would be an inadequate remedy for any such breach.  Accordingly, subject to Section 8 of this Agreement, the Executive agrees that if the Executive breaches, or proposes to breach, any portion of this Agreement, the Employer shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any actual damage to the Employer.

 

8.             Arbitration of Disputes.  Any controversy or claim arising out of or relating to this Agreement or the breach thereof or otherwise arising out of the Executive’s employment or the termination of that employment (including, without limitation, any claims of unlawful employment discrimination whether based on age or otherwise) shall, to the fullest extent permitted by law, be settled by arbitration in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the American Arbitration Association (“AAA”) in Washington, D.C. in accordance with the Employment Dispute Resolution Rules of the AAA, including, but not limited to, the rules and procedures applicable to the selection of arbitrators.  In the event that any person or entity other than the Executive or the Employer may be a party with regard to any such controversy or claim, such controversy or claim shall be submitted to arbitration subject to such other person or entity’s agreement.  Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.  This Section 8 shall be specifically enforceable.  Notwithstanding the foregoing, this Section 8 shall not preclude either party from pursuing a court action for the sole purpose of obtaining a temporary restraining order or a preliminary injunction in circumstances in which such relief is appropriate; provided that any other relief shall be pursued through an arbitration proceeding pursuant to this Section 8.  It is understood that in the event that (a) the Executive initiates an arbitration proceeding for the purpose of challenging a decision by Employer to terminate Executive’s employment for Cause (a “Cause Arbitration”), or (b) Employer initiates an arbitration proceeding for the purpose of challenging a decision by the Executive to resign for Good Reason (whether prior to or after a Change of Control), that time is of the essence and that arbitration of such issues, and the determination of whether the Executive is entitled to Termination Benefits must be completed as soon as practicable.  To the extent permitted by law, the Employer shall be responsible for any fees charged by AAA for a Cause Arbitration unless the arbitrator orders otherwise as a remedy.  The arbitrator will have the power to award all damages that would otherwise be available in a court of law.  The arbitrator shall also award the prevailing party its reasonable costs and attorneys fees unless the arbitrator finds that the non-prevailing party acted in good faith and with a reasonable belief that its conduct was not in violation of this Agreement.

 

9.             Section 409A.

 

(a)           Notwithstanding anything to the contrary in this Agreement, if at the time of the Executive’s termination of employment, the Executive is a “specified employee,” as defined below, any and all amounts payable under this Agreement on account of such separation from service that would (but for this provision) be payable within six (6) months following the date of termination and that constitute nonqualified deferred compensation subject to the

 

9











 

requirements of Section 409A of the Code, shall instead be paid on the next business day following the expiration of such six (6) month period or, if earlier, upon the Executive’s death.

 

(b)           For purposes of this Agreement, all references to “termination of employment” and correlative phrases shall be construed to require a “separation from service” (as defined in Section 1.409A-1(h) of the Treasury regulations after giving effect to the presumptions contained therein), and the term “specified employee” means an individual determined by the Employer to be a specified employee under Treasury regulation Section 1.409A-1(i).

 

(c)           Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments.

 

10.          Consent to Jurisdiction.  To the extent that any court action is permitted consistent with or to enforce Section 8 of this Agreement, the parties hereby consent to the jurisdiction of the courts of the State Maryland and the United States District Court for the District of Maryland.  Accordingly, with respect to any such court action, the Executive (a) submits to the personal jurisdiction of such courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process.

 

11.          Integration.  This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements (including, without limitation, the employment agreement between the Executive and the Employer dated December 22, 2005) between the parties with respect to any related subject matter; provided, that this Agreement shall not supersede the Option Agreement.  The parties agree that in the event of any conflict between the terms of this Agreement and the terms of the Option Agreement, the terms of the Option Agreement shall control.

 

12.
