EMPLOYMENT AGREEMENT 

Between 
 Rentech, Inc. 

and 
 Harold Wright 

THIS AGREEMENT is made effective as of November 3, 2009 between Rentech, Inc. (the “Company”) and Harold Wright
(“Executive”). 
 In consideration of the mutual covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Employment. The Company shall employ
Executive, and Executive hereby agrees to continue employment with the Company, upon the terms and conditions set forth in this Agreement, for the period beginning on November 3, 2009 (the “Effective Date”) and ending as
provided in Section 4 hereof (the “Employment Period”).
 2. Position and Duties. 

(a) During the Employment Period, Executive shall serve as Senior Vice President and Chief Technology Officer of the Company. During the
Employment Period, Executive shall render such administrative, financial and other executive and managerial services to the Company and its affiliates (the “Company Group”) as are consistent with Executive’s position and the
by-laws of the Company and as the Chief Executive Officer (“CEO”) may from time to time reasonably direct. Executive shall also serve for no additional compensation or remuneration as an officer or director of such subsidiaries
of the Company as may from time to time be designated by the CEO or the Board of Directors of the Company (the “Board”). 

(b) During the Employment Period, Executive shall report to the Executive Vice President, Commercial Affairs and Technology and shall devote
his best efforts and his full business time and attention (except for permitted vacation periods and reasonable periods of illness or other incapacity) to the business and affairs of the Company. Executive shall perform his duties,
responsibilities and functions to the Company hereunder to the best of his abilities in a diligent, trustworthy, professional and efficient manner and shall comply with the Company’s policies and procedures in all material respects. In
performing his duties and exercising his authority under this Agreement, Executive shall support and implement the business and strategic plans approved from time to time by the Board and shall support and cooperate with the Company’s efforts
to operate in conformity with the business and strategic plans approved by the Board. During the Employment Period, Executive shall not serve as an officer or director of, or otherwise perform services for compensation for, any other entity
without the prior written consent of the Board which shall not be unreasonably withheld. Executive may serve as an officer or director of or otherwise participate in purely educational, welfare, social, religious and civic organizations so long as
such activities do not interfere with Executive’s regular performance of duties and responsibilities hereunder in any material respect. Nothing contained herein shall preclude Executive from (i) engaging in charitable and community
activities, (ii) participating in industry and trade organization activities, and (iii) managing his and his family’s personal investments and affairs; provided, that Executive shall not have any ownership interest (of record
or beneficial) in any firm, corporation, partnership, proprietorship or other business that competes directly with the Company’s Fischer-Tropsch business except for (x) an investment of not more than 1.0% of the outstanding securities of a
company traded on a public securities exchange or (y) investments made through public mutual funds. 

  








 3. Compensation and Benefits. 

(a) Base Salary. The Company shall pay Executive an annual salary (the “Base Salary”) at the rate of $256,800 in
regular installments in accordance with the Company’s ordinary payroll practices (in effect from time to time), but in any event no less frequently than monthly. Executive shall be eligible for an annual review of his Base Salary based on
performance as determined by the Board in its sole discretion. 
 (b) Bonuses and Incentive Compensation. For each fiscal year ending
during the Employment Period, Executive will be eligible to earn an annual bonus based on achievement of performance criteria established by the Board as soon as administratively practicable following the beginning of each such fiscal year (the
“Annual Bonus”). The target amount (the “Target Bonus”) of Executive’s Annual Bonus shall equal 50% of Executive’s Base Salary (at the annual rate in effect at the start of the fiscal year), with a
maximum Annual Bonus in an amount equal to 100% of Executive’s Base Salary (at the annual rate in effect at the start of the fiscal year). For the avoidance of doubt, the amount of any Annual Bonus may be less than the Target Bonus (and may
equal zero), as determined in the sole discretion of the Board or the Board’s Compensation Committee. The Company shall pay the Annual Bonus for each fiscal year after the end of the Company’s fiscal year in accordance with procedures
established by the Board, but in no event later than the fifteenth day of the third month following the end of such fiscal year. To be eligible for an Annual Bonus pursuant to this Section 3(b), Executive must be an employee of the Company on
the last day of the relevant fiscal year. 
 (c) Expenses. During the Employment Period, the Company shall, subject to Section 19
below, (i) reimburse Executive for all reasonable business expenses incurred by him in the course of performing his duties and responsibilities under this Agreement in accordance with the Company’s policies in effect from time to time with
respect to travel, entertainment and other business expenses for senior executives and (ii) pay to Executive a monthly automobile allowance of $1,000. 

(d) Other Benefits. Executive shall also be entitled to the following benefits during the Employment Period: 

(i) participation in the Company’s retirement plans, health and welfare plans, disability insurance plans and other benefit plans of the
Company as in effect from time to time, under the terms of such plans and to the same extent and under the same conditions such participation and coverages are provided generally to other senior executives of the Company; 

(ii) coverage for services rendered to the Company, its subsidiaries and affiliates while Executive is a director or officer of the Company, or
of any of its subsidiaries or affiliates, under director and officer liability insurance policy(ies) maintained by the Company from time to time; and 

(iii) five weeks of vacation per year. 
 Nothing
contained in this Section 3(d) shall, or shall be construed so as to, obligate the Company to adopt or maintain any plan, program or policy at any time.

 4. Termination. The Employment Period shall end on the first anniversary of the Effective Date;
provided, however, that the Employment Period shall be automatically renewed for successive one-year terms thereafter on the terms and conditions of this Agreement in effect at the time of such renewal unless either party provides the
other party with notice that it has elected not to renew the Employment Period at least 90 days prior to the end of the initial Employment Period or any subsequent extension thereof. Notwithstanding the foregoing, (i) the Employment Period
shall terminate immediately upon Executive’s resignation (with or without Good Reason, as defined herein), death or Disability (as defined herein) and (ii) the Employment Period may be terminated by the Company at any time prior to such
date for Cause (as defined herein) or without Cause. Except as otherwise provided herein, any termination of the Employment Period by the Company shall be effective as specified in a written notice from the Company to Executive, but in no event
more than 90 days from the date of such notice. The termination of the Employment Period shall not affect the respective rights and obligations of the parties which, pursuant to the terms of this Agreement, apply following the date of
Executive’s termination of employment with the Company. 
 5. Severance. 

(a) Termination Without Cause or for Good Reason. In the event that Executive incurs a “separation from service” from the
Company (within the meaning of Section 409A(a)(2)(A)(i) of the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury Regulation Section 1.409A-1(h)) (“Separation from Service”) (1) by
the Company without Cause (as defined herein), or (2) by Executive for Good Reason (as defined herein), then, subject to Executive’s execution and non-revocation of a Release substantially in the form attached as Exhibit A

Section 409A (as defined below). 
 (i) The Company shall pay Executive an amount equal to one times Executive’s Base Salary plus
one times Executive’s Target Bonus (as in effect on the date of Executive’s termination). The severance amount described in the previous sentence shall be paid as follows, subject to Section 19 below: (A) the continuation of
Base Salary shall be paid in substantially equal installments over a period of one year from Executive’s Separation from Service in accordance with the payroll practices of the Company in effect from time to time, beginning on the first payroll
date occurring on or after the thirtieth day following Executive’s Separation from Service (such payroll date, the “First Payroll Date”) (with amounts otherwise payable prior to the First Payroll Date paid on the First Payroll
Date) and (B) the Target Bonus shall be paid on the date that executive bonuses are paid generally for the fiscal year in which the date of termination took place, which shall, in any event, be no earlier than the First Payroll Date and no
later than two and one-half months after the end of such fiscal year; 
 (ii) Any outstanding equity awards held by Executive shall be
governed by the terms of the applicable award agreements. 
 (iii) Executive shall be entitled to benefits mandated under the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), under Section 4980B of the Code, or any replacement or successor provision of United States tax law, subject to Executive’s valid election to receive COBRA
benefits, with the premium paid at the Company’s expense until the first to occur of (A) eighteen months from the date of termination, (B) the expiration of the period of time during which Executive is entitled to continuation
coverage under the Company’s group health plan under COBRA, or (C) such date that Executive becomes eligible for coverage under the group health plan of another employer, provided, that if any plan pursuant to which such benefits
are provided is not, or ceases prior to the expiration of the period of continuation coverage to be, exempt from the application of Section 409A under Treasury Regulation Section 1.409A-1(a)(5), then an amount equal to each remaining
premium payment shall thereafter be paid to Executive as currently taxable compensation in substantially equal monthly installments over the continuation coverage period (or the remaining portion thereof).

 In addition, if Executive’s employment terminates pursuant to this Section 5(a), the
Company shall pay Executive the amounts described in Section 5(d)(i), (ii) and (iii) within 30 days of the date of termination (or such earlier date as may be mandated by applicable law) and shall pay or provide the other benefits

(iii) within 30 days of the date of termination (or such earlier date as may be mandated by applicable law) and shall pay or provide the other benefits described in Section 5(d) in accordance therewith. 

For purposes of this Agreement, Executive’s voluntary resignation or retirement shall be considered Executive’s resignation from the
Company without Good Reason. 
 (c) Death or Disability. In the event that Executive’s employment with the Company is

the Board or the Board’s Compensation Committee and communicated to Executive prior to Executive’s termination of employment, (iii) any vacation pay, expense reimbursements and other cash entitlements accrued by Executive, in
accordance with Company policy for senior executives, as of the date of termination to the extent not previously paid, and (iv) all vested benefits accrued by Executive under all benefit plans and qualified and nonqualified retirement, pension,
401(k) and similar plans and arrangements of the Company, in such manner and at such times as are provided under the terms of such plans and arrangements. Any equity awards held by Executive that are outstanding at the time of termination shall be
governed by the terms of the plans or arrangements under which such awards were created or maintained. 
 (e) Termination Without Cause,
Non-Renewal or for Good Reason Following a Change in Control. In the event that Executive incurs a Separation from Service during the period beginning three months before and ending two-years immediately following a Change in Control (as
defined herein) of the Company (1) by the Company without Cause, (2) as a result of the Company electing not to renew the Agreement in accordance with Section 4 above on terms and conditions substantially similar to those contained

 4 








 (i) The Company shall pay Executive the payments set forth in Section 5(a)(i) in accordance
with the terms and conditions set forth in Section 5(a); provided, however, that in determining the amount of payment due under Section 5(a)(i), Executive’s actual Annual Bonus for the year preceding the Change in
Control shall be used, if higher than his Target Bonus; and provided, further, that, subject to Section 19 below, payments pursuant to Sections 5(a)(i) shall be made in a lump sum (A) if the Separation from Service occurs
during the three-month period preceding the Change in Control, on the 95th day following such Separation from Service (to the extent not previously paid in accordance with Section 5(a)(i)),

described in Section 5(d)(i), (ii) and (iii) within 30 days of the date of termination (or such earlier date as may be mandated by applicable law) and shall pay or provide the other benefits described in Section 5(d) in
accordance therewith. 
 (f) Non-Renewal. In the event that Executive incurs a Separation from Service as a result of the
Company electing not to renew the Agreement in accordance with Section 4 above on terms and conditions substantially similar to those contained herein and, (A) at the time of such non-renewal, Executive is willing and able to continue
providing services on terms and conditions substantially similar to those contained in this Agreement and (B) Section 5(e) does not apply to such non-renewal, then, subject to Executive’s execution and non-revocation of a Release
substantially in the form attached as Exhibit A within 30 days after such Separation from Service, Executive shall be entitled to the benefits set forth below in this Section 5(f). 

(i) The Company shall pay Executive an amount equal to twelve months of Executive’s Base Salary (as in effect on the date of
Executive’s termination), which amount shall, subject to Section 19 below, be paid in substantially equal installments over a period of twelve months from Executive’s Separation from Service in accordance with the payroll practices of

payment for purposes of Section 409A. In addition, upon a non-renewal described in this Section 5(f), if Executive has not already been awarded an Annual Bonus in respect of the fiscal year immediately preceding such non-renewal, the
Company may, in its sole discretion, award some portion of an Annual Bonus to Executive in respect of such fiscal year based on Executive’s service and the attainment of applicable performance objectives during such fiscal year.

to such Payment (through withholding or otherwise), an additional amount (a “Gross-Up Payment”) which, after the imposition of all income, employment, excise and other taxes, penalties and interest thereon, is equal to the sum of
(A) the Excise Tax on such Payment plus (B) any penalty and interest assessments associated with such Excise Tax. 
 (ii) The
determinations to be made with respect to this Section 5(g) shall be made by a certified public accounting firm designated by the Company and reasonably acceptable to Executive and Executive may rely on such determination in making

any income or other taxes to be paid by the Company under this Section 5(g) shall be made by the Company no later than the end of Executive’s taxable year next following Executive’s taxable year in which Executive remits the related

Executive’s termination of employment for whatever reason, Executive shall be under no obligation to seek other employment, and there shall be no offset against amounts due him under this Agreement or otherwise on account of any remuneration
attributable to any subsequent employment or claims asserted by the Company or any affiliate, provided, that this provision shall not apply with respect to any amounts that Executive owes to the Company or any member of the Company Group on

any successor (whether direct or indirect, by purchase, merger, reorganization, consolidation, acquisition of property or stock, liquidation, or otherwise) to all or a majority of its assets, by agreement in form and substance satisfactory to
Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform this Agreement if no such succession had taken place. Executive may not assign his rights
(except by will or the laws of descent and distribution or to a trust for the purpose of estate or tax planning for the benefit of Executive’s spouse and/or children) or delegate his duties or obligations hereunder. Except as provided by
this Section 16, this Agreement is not assignable by any party and no payment to be made hereunder shall be subject to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or other charge. 

17. Choice of Law. All issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement and the
exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the State of California regardless of the law that might be applied under principles of conflicts of laws. 

18. Amendment and Waiver. The provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and
Executive, and no course of conduct or course of dealing or failure or delay by any party hereto in enforcing or exercising any of the provisions of this Agreement (including, without limitation, the Company’s right to terminate the Employment
Period for Cause) shall affect the validity, binding effect or enforceability of this Agreement or be deemed to be an implied waiver of any provision of this Agreement. 

19. Internal Revenue Code Section 409A. 

(a) General. To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Code and
Department of Treasury regulations and other interpretative guidance issued thereunder, including without limitation any such regulations or other such guidance that may be issued after the Effective Date (“Section 409A”).
Notwithstanding any provision of this Agreement to the contrary, in the event that following the Effective Date, the Company determines in good faith that any compensation or benefits payable under this Agreement may not be either exempt from or
compliant with Section 409A, the Company shall consult with Executive and adopt such amendments to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effective), or take any
other commercially reasonable actions necessary or appropriate to (i) preserve the intended tax treatment of the compensation and benefits payable hereunder, to preserve the economic benefits of such compensation and benefits, and/or to avoid
less favorable accounting or tax consequences for the Company and/or (ii) to exempt the compensation and benefits payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application
of penalty taxes thereunder; provided, however, that this Section 19(a) does not, and shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any
other such actions or to indemnify the Executive for any failure to do so. 
 (b) Specified Employee. Notwithstanding anything to the
contrary in this Agreement, no compensation or benefits, including without limitation any severance payment under Section 5 above, shall be paid to Executive during the 6-month period following his Separation from Service to the extent that the
Company determines that Executive is a “specified employee” at the time of such Separation from Service (within the meaning of Section 409A) and that that paying such amounts at the time or times indicated in this Agreement would be a
prohibited distribution under Section 409A(a)(2)(b)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such 6-month period (or such earlier
date upon which such amount can be paid under Section 409A without being subject to such additional taxes, including as a result of Executive’s death), the Company shall pay to Executive a lump-sum amount equal to the cumulative amount
that would have otherwise been payable to Executive during such 6-month period, along with interest at the prime rate (as reported in the Wall Street Journal or such other source as the Company deems reliable) from the date such payments were
otherwise due to the date of payment. The Company’s determination as to whether such six-month delay is required by this sub-paragraph shall be made in good faith by the Company after consultation between the Company and Executive. 

  
 11 








 (c) Reimbursements. To the extent that any reimbursements, including without limitation
any reimbursements pursuant to Section 3(c) above, are determined to constitute taxable compensation to Executive, then such reimbursements shall be paid to Executive promptly following proper substantiation in accordance with applicable
Company policy, but in no event after December 31st of the year following the year in which the expense was incurred (and such reimbursements shall be contingent upon Executive’s timely
submission of proper substantiation). The amount of any such expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year and Executive’s right to reimbursement of any such expenses shall not be
subject to liquidation or exchange for any other benefit. 
 20. Insurance. The Company may, at its discretion, apply for and procure in its own
name and for its own benefit life and/or disability insurance on Executive in any amount or amounts considered advisable. Executive agrees to cooperate in any medical or other examination, supply any information and execute and deliver any
applications or other instruments in writing as may be reasonably necessary to obtain and constitute such insurance. Executive hereby represents that he has no reason to believe that his life is not insurable at rates now prevailing for healthy
men of his age. 
 21. Withholding. Any payments made or benefits provided to Executive under this Agreement shall be reduced by any applicable
withholding taxes or other amounts required to be withheld by law or contract. 
 22. Arbitration. Any dispute or controversy arising under or in
connection with this Agreement or otherwise in connection with the Executive’s employment by the Company that cannot be mutually resolved by the parties to this Agreement and their respective advisors and representatives shall be settled
exclusively by arbitration in Los Angeles, California in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who shall be selected jointly by an individual to be
designated by the Company and an individual to be selected by Executive, or if such two individuals cannot agree on the selection of the arbitrator, who shall be selected by the American Arbitration Association. The Company will pay the direct costs
and expenses of any such arbitration, including the fees and costs of the arbitrator; provided, however, that the arbitrator may, at his or her election, award attorneys’ fees to the prevailing party, if permitted by applicable
law. 
 23. Executive’s Cooperation. During the Employment Period and thereafter, Executive shall cooperate with the Company and its
affiliates, upon the Company’s reasonable request, with respect to any internal investigation or administrative, regulatory or judicial proceeding involving matters within the scope of Executive’s duties and responsibilities to the Company
Group during the Employment Period (including, without limitation, Executive being available to the Company upon reasonable notice for interviews and factual investigations, appearing at the Company’s reasonable request to give testimony
without requiring service of a subpoena or other legal process, and turning over to the Company all relevant Company documents which are or may come into Executive’s possession during the Employment Period); provided, however,
that any such request by the Company shall not be unduly burdensome or interfere with Executive’s personal schedule or ability to engage in gainful employment. In the event the Company requires Executive’s cooperation in
accordance with this Section 23, the Company shall reimburse Executive for reasonable out-of-pocket expenses (including travel, lodging and meals) incurred by Executive in connection with such cooperation, subject to reasonable documentation.
In the event that the obligations under this Section 23 require more than 20 hours of the Executive’s time after the termination of the Employment Period, the Company shall thereafter also pay to Executive compensation at an hourly rate
equal to the result of (a) the Base Salary applicable on the date of the termination of Executive’s employment, divided by (b) 1,750.

 EXHIBIT A 

FORM OF RELEASE 
 This General Release of all
Claims (this “Agreement”) is entered into by Harold Wright (“Executive”) and Rentech, Inc. (the “Company”), effective as of
[            ]. 
 In further consideration of the promises and mutual obligations set forth in

1. Return of Property. All Company files, access keys, desk keys, ID badges, computers, electronic devices, telephones and credit cards, and such other

(a) Release. In consideration of the payments and benefits provided to Executive under the Employment Agreement and after consultation

provided, however, that Executive does not release, discharge or waive any rights to payments and benefits provided under the Employment Agreement that are contingent upon the execution by Executive of this Agreement, any vested

 1 








 THE EXECUTIVE ACKNOWLEDGES THAT HE HAS BEEN ADVISED OF AND IS FAMILIAR WITH THE PROVISIONS OF
CALIFORNIA CIVIL CODE SECTION 1542, WHICH PROVIDES AS FOLLOWS: 
 “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH, IF KNOWN BY HIM OR HER, MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” 

BEING AWARE OF SAID CODE SECTION, THE EXECUTIVE HEREBY EXPRESSLY WAIVES ANY RIGHTS HE MAY HAVE THEREUNDER, AS WELL AS UNDER ANY OTHER STATUTES
OR COMMON LAW PRINCIPLES OF SIMILAR EFFECT. 
 (b) Specific Release of ADEA Claims. In further consideration of the payments and
benefits provided to Executive under the Employment Agreement, the Releasors hereby unconditionally release and forever discharge the Releasees from any and all Claims that the Releasors may have as of the date Executive signs this Agreement arising
under the Federal Age Discrimination in Employment Act of 1967, as amended, and the applicable rules and regulations promulgated thereunder (“ADEA”). By signing this Agreement, Executive hereby acknowledges and confirms the
following: (i) Executive was, and is hereby, advised by the Company in connection with his termination to consult with an attorney of his choice prior to signing this Agreement and to have such attorney explain to Executive the terms of this
Agreement, including, without limitation, the terms relating to Executive’s release of claims arising under ADEA, and Executive has in fact consulted with an attorney; (ii) Executive was given a period of not fewer than 21 days to consider
the terms of this Agreement and to consult with an attorney of his choosing with respect thereto; (iii) Executive knowingly and voluntarily accepts the terms of this Agreement; (iv) the payments and benefits provided to Executive in
consideration of this release are in addition to any amounts otherwise owed to Executive; and (v) this Agreement is written in a manner designed to be understood by Executive and he understands it. Executive also understands that he has seven
days following the date on which he signs this Agreement within which to revoke the release contained in this paragraph, by providing the Company a written notice of his revocation of the release and waiver contained in this paragraph. 

(c) No Assignment. Executive represents and warrants that he has not assigned any of the Claims being released under this Agreement.

 3. Proceedings. Executive has not filed, and agrees not to initiate or cause to be initiated on his behalf, any complaint, charge, claim or
proceeding against the Releasees before any local, state or federal agency, court or other body relating to any Claims released under this Agreement, including without limitation, any Claims relating to his employment or the termination of his
employment, (each, individually, a “Proceeding”), and agrees not to participate voluntarily in any Proceeding. Notwithstanding the foregoing, Executive may bring to the attention of the United States Equal Employment Opportunity
Commission (the “EEOC”) claims of discrimination. Executive waives any right he may have to benefit in any manner from any relief (whether monetary or otherwise) arising out of any Proceeding. 

  
 2 








 4. Remedies. In the event Executive initiates or voluntarily participates in any Proceeding, or if he
fails to abide by any of the terms of this Agreement or his post-termination obligations contained in the Employment Agreement, or if he revokes the ADEA release contained in Paragraph 2(b) of this Agreement within the seven-day period provided
under Paragraph 2(b), the Company may, in addition to any other remedies it may have, reclaim any amounts paid to him under the severance provisions of the Employment Agreement or terminate any benefits or payments that are subsequently due under
the Employment Agreement, without waiving the release granted herein. The foregoing shall not apply to Executive’s bringing to the attention of the EEOC any claims of discrimination. Executive acknowledges and agrees that the remedy at law
available to the Company for breach of any of his post-termination obligations under the Employment Agreement or his obligations under Paragraphs 2 and 3 of this Agreement would be inadequate and that damages flowing from such a breach may not
readily be susceptible to being measured in monetary terms. Accordingly, Executive acknowledges, consents and agrees that, in addition to any other rights or remedies that the Company may have at law or in equity, the Company shall be entitled to
seek a temporary restraining order or a preliminary or permanent injunction, or both, without bond or other security, restraining Executive from breaching his post-termination obligations under the Employment Agreement or his obligations under
Paragraphs 2 and 3 of this Agreement. Such injunctive relief in any court shall be available to the Company, in lieu of, or prior to or pending determination in, any arbitration proceeding. 

Executive understands that by entering into this Agreement he will be limiting the availability of certain remedies that he may have against
the Company and limiting also his ability to pursue certain claims against the Company. 
 5. Severability Clause. In the event any provision or part
of this Agreement is found to be invalid or unenforceable, only that particular provision or part so found, and not the entire Agreement, will be inoperative. 

6. Non-admission. Nothing contained in this Agreement will be deemed or construed as an admission of wrongdoing or liability on the part of the Company.

 7. Governing Law. All matters affecting this Agreement, including the validity thereof, are to be governed by, and interpreted and construed in
accordance with, the laws of the State of California regardless of the law that might be applied under principles of conflicts of laws. 
 8.
Arbitration. Any dispute or controversy arising under or in connection with this Agreement or otherwise in connection with Executive’s employment by the Company that cannot be mutually resolved by the parties to this Agreement and their
respective advisors and representatives shall be settled exclusively by arbitration in Los Angeles, California in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who
shall be selected jointly by an individual to be designated by the Company and an individual to be selected by Executive or, if such two individuals cannot agree on the selection of the arbitrator, who shall be selected by the American Arbitration
Association. The Company will pay the direct costs and expenses of any such arbitration, including the fees and costs of the arbitrator; provided, however, that the arbitrator may, at his or her election, award attorneys’ fees to
the prevailing party, if permitted by applicable law. 
 9. Notices. All notices or communications hereunder shall be in writing, addressed as
