RE: Transition and Consulting Services Agreement

Dear Doug,

Griffon Corporation (the “Company”) has agreed to accommodate your expressed wish to retire.  You confirm that your retirement is not as a result of any disagreement with the Company regarding the operations, disclosures, policies and practices of the Company and its subsidiaries.  We wish to confirm the arrangements to which you and the Company have agreed and pursuant to which you will provide certain transition and consulting services to the Company following your retirement.

This letter agreement (this “Agreement”) (i) confirms your retirement, effective July 31, 2015 (the “Effective Date”), as an Executive Vice President and as the Chief Financial Officer of the Company and from all other positions that you hold with the Company, its subsidiaries and all committees of which you are a member (and you hereby resign from all such offices, positions and memberships effective July 31, 2015 and agree to promptly sign all documents and take such other actions that the Company deems necessary or desirable to give effect to such resignations); and (ii) sets forth the terms and conditions regarding the transition and consulting services you agree to provide to the Company following the Effective Date. This letter supersedes and replaces all obligations that the Company and/or any subsidiary thereof has to you with respect to your compensation and benefits commencing with the Effective Date.

You and the Company agree that, for purposes of your employment agreement with the Company, dated August 6, 2009 (the “Employment Agreement”), and, except as otherwise expressly set forth in this Agreement with respect to the restricted stock awards set forth in Section 2(d) below, your retirement on the Effective Date will be treated as a termination under Section 9(a) of the Employment Agreement. You acknowledge and agree that the Company’s obligation to pay you the amounts set forth in this Agreement will be contingent on your compliance with all of the terms and conditions set forth herein.

Transition and Consulting Services.

(a)Term. The term of the transition and consulting services under this Agreement will begin on August 1, 2015 and continue until November 30, 2017, unless terminated earlier pursuant to Section 3 below (the “Term”).

(a)Consulting Services. During the Term, you will perform such transition and consulting services for the Company as are reasonably requested from time to time by the Company’s Chief Executive Officer, Chief Operating Officer and/or Chief Financial Officer (the “Consulting Services”). You will devote your reasonable best efforts for up to 8 hours per week during normal business hours to the performance of the Consulting Services. You will provide the Consulting Services telephonically or by email exchange whenever possible and, subject to reasonable advance notice, in-person only when requested. You will not have an office at any Company location, any Company car or driver entitlement or any secretarial or administrative assistance. You may engage in such other pursuits during the term of this Agreement as shall not interfere with the performance of your duties or the observance of your obligations under this Agreement, subject to offset as provided in Sections 2 and 3 below.

(b)Release of Claims. On or within three business days following July 31, 2015, you shall execute and deliver to the Company a release of claims in the form set forth in Section 5 below (the “Release”). If you fail to execute the Release on or within three business days following July 31, 2015 or if you subsequently revoke the Release within the applicable revocation period, the Term shall immediately terminate and you shall not be entitled to any payments or benefits hereunder or under the restricted stock awards described in Section2(d).

2.Fees and Other Entitlements.

(a)Consulting Fee. During the Term, you will be entitled to a monthly consulting fee, payable in arrears, equal to $35,785; subject to offset for any compensation you receive for any employment other than consulting assignments and board of director appointments as an independent director that, in each case, do not violate Section 6 or any other provision of this Agreement.

(b)Expense Reimbursement. During and in respect of the Term, you will be reimbursed for all reasonable expenses incurred by you in the performance of the Consulting Services hereunder in accordance with the Company’s expense reimbursement policy, as in effect from time to time. Notwithstanding the above, any expense in excess of $100 must be approved in writing in advance by the Company’s Chief Operating Officer.

(c)FYE 2015 Bonus. Subject to your continued service with the Company hereunder (except as provided below) and the attainment of applicable performance criteria and levels of performance achievement adopted by the Compensation Committee in December 2014, the Company will pay you a maximum bonus in the amount of $600,000 even if performance achievement would result in a bonus in excess of this maximum amount (pro-rated in the event of your termination due to death or Disability (as defined in Section 3 below) prior to September 30, 2015) for the fiscal year ending September 30, 2015 at such time as the Company pays bonuses for such fiscal year to its senior executives generally, but in no event later than March 15, 2016.

(d)Equity Awards. During the Term, you will have the opportunity to vest in the restricted stock awards granted to you by letter agreement dated February 11, 2011 (90,000 shares), as amended on January 10, 2012 (“2011 Award”), the restricted stock award granted to you by letter agreement dated January 29, 2013 (41,667 shares) (“2013 Award”), and the restricted stock award granted to you by letter agreement dated January 30, 2014 (29,433 shares) (“2014 Award”) (collectively, the “Awards”) in accordance with the terms and conditions of the 2011 Equity Incentive Plan (the “2011 Plan”) and each applicable Award, except as is otherwise expressly provided by Section 3 of this Agreement, and subject to your continued compliance with this Agreement, with the term “service” in each of the Awards to include Consulting Services under Section 1(b) of this Agreement, and the phrase “, so long as any such amendment is made equally for all executives having the same Award (other than in connection with the number of covered shares)” is added to the end of the first sentence of the ninth paragraph of the 2011 Award, the first sentence of the tenth paragraph of the 2013 Award and the first sentence of the twelfth paragraph of the 2014 Award. The Closing Price Target under the 2011 Award was met on April 22, 2015. As of the Effective Date, you agree that you will forfeit the 25,000 restricted shares granted to you on January 28, 2015 with no compensation due therefor.

(e)The determination of achievement against the applicable performance goals and performance criteria, for purposes of the 2015 Bonus under Section 2(c) above and the Awards under Section 2(d) above, together with the level of attainment determined by the Compensation Committee under such 2015 Bonus and under each Award, will be determined by the Compensation Committee in the same manner as for the other senior executive officers covered by the 2015 Bonus plan or such Award, as applicable, and without exercise of negative discretion to reduce the amount of any payment or benefit to you thereunder, except to the extent that negative discretion is exercised in respect of other senior executives and in proportion thereto.

During the first 18 months of the Term or, if earlier, only until you become eligible for medical benefits from a subsequent employer, (i) the Company will directly pay the premiums under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, for the continuation of your last elected medical, dental and vision coverage, as applicable, for you and your dependent children (and, as to dental coverage, your spouse) and (ii) you will continue to participate in the Company’s Supplemental Health Benefits Plan for Senior Executives (“Supplemental Plan”) (with a maximum benefit payable under the Supplemental Plan of up to $10,000 in calendar year 2015, up to $10,000 in calendar year 2016 and up to $833 for the portion of calendar year 2017 ending on January 31, 2017), provided that such COBRA benefits and participation in such Supplemental Plan do not (x) violate any applicable law or regulation and does not result in penalties or similar costs to the Company under applicable law or regulation or (y) contravene the terms and provisions of any insurance policy or plan provision (which cannot be amended to accommodate such participation on a commercially reasonable basis). If, and only if, the Company is prevented by application of clauses (x) and/or (y) above from providing you the premium payment benefits described in clause (i) above, then, provided that doing so will not violate any applicable law or regulation and does not result in penalties or similar costs to the Company under applicable law or regulation, the Company will pay you an amount in cash equal to the amount of premium it would have otherwise paid under clause (i) on your behalf.

(g)Indemnification. You will be entitled to the rights set forth in Section 25 of the Employment Agreement (with the Employment Term therein to include the Term) and in your Indemnification Agreement with the Company, dated August 6, 2013 (the “Indemnification Agreement”), in accordance with the terms thereof. This Section 2(g) will survive any termination or expiration of this Agreement.

(h)Insurance. The Company will pay the premium for one year of additional coverage under the life insurance policy purchased by the Company on your life on or as soon as reasonably practicable following the first renewal date for such policy following the date hereof. The Company agrees to reasonably cooperate with you to facilitate your assumption, continuation and/or conversion, as the case may be, at your cost, of such life insurance policy thereafter.

(i)Computer. You shall be permitted to retain your Company-issued computer following the Effective Date and the termination of the Term; provided that you shall deliver such computer to the Company’s information technology department on or prior to July 31, 2015 for inspection and removal (in your presence, if you so desire) of all proprietary information of the Company and its subsidiaries and affiliates, and, if requested by the Company, within a reasonable period of time after the termination of the Term. During the Term, you will not be provided a Company email address and you will not be given access to the Company’s computer networks.

Upon the termination of the Term and your service hereunder by you or the Company for any reason, you will be entitled to any rights you may have under Section 2(d) above as of the date of any such termination and the Company will (i) pay you any earned and accrued (but unpaid) portion of your consulting fee under Section 2(a) as of the termination date and (ii) reimburse you for any unreimbursed expenses in accordance with Section 2(b) as of the termination date; provided that if such termination of the Term and your service hereunder is by the Company without Cause, then, subject to your continued compliance with the terms and provisions of this Agreement, the Company will also (A) continue to pay you the consulting fee under Section 2(a) until November 30, 2017, subject to offset for any compensation you receive for any employment after the earlier termination of the Term other than consulting assignments and board of director appointments as an independent director that, in each case, do not violate Section 6 or any other provision of this Agreement; (B) pay you any bonus earned but not paid for the fiscal year ending September 30, 2015 in accordance with Section 2(c); (C) continue to provide you the COBRA benefits and supplemental medical benefits described in Section 2(f) for the period set forth therein or, if earlier, only until you become eligible for medical benefits from a subsequent employer; (D) provide for the continued opportunity to vest in the equity awards described in Section 2(d) until November 30, 2016 in accordance with and subject to your compliance with the terms and conditions of this Agreement and, except as otherwise expressly provided herein, the Plan and the applicable Award agreements; and (E) you will continue to have all of your rights under Sections 2(e), (g), (h) and (i), 6(e)(ii), 10, 11, 14, 15 and 17 of this Agreement. Notwithstanding anything herein to the contrary, (I) in the event of your termination due to death or Disability prior to September 30, 2015 you will also be paid a pro-rata portion of the bonus earned but not paid for the fiscal year ending September 30, 2015 in accordance with and subject to Section 2(c); (II) in the event of your termination due to Disability prior to the first renewal date following the date hereof for the life insurance policy described in Section 2(h), the Company will pay the premium for one additional year of coverage thereunder in accordance with Section 2(h); (III) in the event of your termination due to death or Disability, the Company will continue to provide you the COBRA benefits and supplemental medical benefits described in Section 2(f) for the period set forth therein or, if earlier, only until you become eligible for medical benefits from a subsequent employer; and (IV) in the event of your termination due to death or Disability prior to November 30, 2016, notwithstanding anything to the contrary in the applicable award agreements and to the extent not previously forfeited, (i) the 2011 Award will vest on April 22, 2016, (ii) you will continue to have the opportunity to vest in the 2013 Award until November 30, 2016, and (iii) the 2014 Award will vest on the date of such termination, in each case, subject to the satisfaction of all other applicable terms and conditions, including, without limitation, the attainment of all applicable performance criteria.

From the date hereof until November 30, 2017 (the “Non-Solicit Period”), you will not, for any reason, solicit, assist or encourage the solicitation of, or employ any person who was a full-time employee of, or independent contractor to, the Company or its subsidiaries or affiliates on the date of your termination of employment and/or Consulting Services hereunder, or within six (6) months prior thereto, to work for an entity other than the Company. For this purpose, the term “solicit” will include, but not be limited to, contacting, or providing information to others who may be reasonably expected to contact, any employee or independent contractor of the Company or its subsidiaries or affiliates regarding such employee’s or independent contractor’s interest in seeking employment or engagement with an entity other than the Company.

(c)Non-Solicitation of Clients or Customers/Non-Interference with Vendors. During the Non-Solicit Period, you will not, for any reason, solicit or encourage any vendor, Client or Prospective Client to cease any relationship with the Company or any of its subsidiaries or affiliates, or to cease any service in any way to or from any Client or Prospective Client. For this purpose, the term “solicit” will mean contacting, or providing information to others who may be reasonably expected to contact, any such vendor, Client or Prospective Client of the Company or any of its subsidiaries or affiliates regarding such Client or Prospective Client’s interest in receiving your services or the services of any entity with which you are affiliated or the cessation of any such relationship. The term “Client” will mean all persons for whom the Company or any of its subsidiaries or affiliates currently maintains an active account or file in the active records of the Company or any such subsidiary or affiliate, or for whom the Company or any of its subsidiaries or affiliates have otherwise performed or performs any services or provided products within the twelve (12) month period preceding your termination of employment or Consulting Services hereunder. The term “Prospective Client” means those persons and entities who have been approached by or on behalf of the Company or any of its subsidiaries or affiliates to become a client or who have been entered into the internal records of the Company or any of its subsidiaries or affiliates as a prospective or potential client.

(d)Non-Compete. You expressly covenant and agree that during the Non-Solicit Period, you will not directly or indirectly, own, manage, operate, join, control, receive compensation or benefits from, or participate in the ownership, management, operation, or control of, or be employed by, serve as a director of, consult for or be otherwise connected in any manner with, any business which directly or indirectly competes in any material manner with any of the businesses of the Company or any of its subsidiaries or affiliates, as conducted or planned by the Company or any of its subsidiaries or affiliates during your employment with the Company.

(e)Mutual Non-Disparagement.

(i)You agree that, during your employment or other service with or to the Company and at all times thereafter, you will not defame, disparage or publicly criticize the Company and/or its subsidiaries or affiliates and/or their executive officers or directors to any person or entity. Subsequent to your termination of employment or other service for any reason, you will not speak in a negative or disparaging manner about the Company (and/or its subsidiaries, affiliates, executive officers, directors and/or its business), to the media, whether electronic, print or otherwise, without the prior written approval of the Company. Nothing herein, however, will prohibit you from making truthful statements to the extent legally compelled or otherwise required by applicable laws or governmental regulations or judicial or regulatory proceedings.

(ii)The Company agrees that, during your employment or other service with or to the Company and at all times thereafter, it (and/or its subsidiaries or affiliates) and the Company’s executive officers will not (i) defame, disparage or publicly criticize you, or (ii) speak in a negative or disparaging manner about you to the media, whether electronic, print or otherwise, without your prior written approval. Nothing herein, however, will prohibit the Company, its subsidiaries or affiliate or their executive officers from making truthful statements to the extent legally compelled or otherwise required by applicable laws or governmental regulations or judicial or regulatory proceedings.

(f)Survival. You understand and agree that the rights and obligations set forth in this Section 6 may extend beyond the Term.

(g)Remedies/Sanctions. You acknowledge that the services you rendered under the Employment Agreement are of a unique and special nature, the loss of which cannot reasonably or adequately be compensated for in monetary damages, and that irreparable injury and damage may result to the Company or any of its subsidiaries or affiliates in the event of any breach of this Agreement or default by you. Because of the unique nature of the Confidential Information and the importance of the prohibitions against competition and solicitation, you further acknowledge and agree that the Company and its subsidiaries and affiliates will suffer irreparable harm if you fail to comply with you obligations under Section 6 and that monetary damages would be inadequate to compensate the Company for any such breach. Accordingly, you agree that, in addition to any other remedies available to either party at law, in equity or otherwise, the Company will be entitled to seek injunctive relief or specific performance to enforce the terms, or prevent or remedy the violation, of any provisions of this Agreement.

(h)Clawback.

7.Your Representations. You hereby affirm and acknowledge:

(a)You have not filed, caused to be filed, or presently are a party to any claim, complaint, or action against any of the Released Parties herein in any forum or form.

8.Amendments. This Agreement may not be modified, altered, or amended except in writing and signed by you and the Company. You acknowledge that you have not relied on any representations, promises, or agreements of any kind made to you in connection with your decision to enter into this Agreement.

9.Governing Law and Jurisdiction. This Agreement will be governed by and construed and interpreted in accordance with the laws of the State of New York without reference to principles of conflict of laws thereof. Each party irrevocably submits to the exclusive jurisdiction of both the Supreme Court of the State of New York, New York County and the United States District Court for the Southern District of New York (collectively, the “New York Courts”) for the purposes of any suit, action or other proceeding permitted by and arising out of this Agreement. Each party irrevocably and unconditionally waives any objection to the laying of venue of any legal proceeding brought in compliance with this Agreement in the New York Courts, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such proceeding brought in any New York Court has been brought in an inconvenient forum.

10.Arbitration. Any contest or dispute arising under this Agreement will be submitted to binding arbitration for resolution in New York, New York, in accordance with the applicable rules of the American Arbitration Association then in effect; provided, however, that the Company may bring an action in any court of law or equity to specifically enforce any confidentiality, non-compete, non-interference, non-disparagement or non-solicitation covenant, and you may bring an action in any court of law or equity to enforce the Company’s non-disparagement covenant under Section 6(e) or your rights to indemnification or expense advancement. Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. The costs of commencing such arbitration will be borne equally by the parties.

11.Legal Fees. The Company will reimburse you for up to $10,000 in reasonable legal fees incurred by you in the negotiation of this Agreement, subject to your submission of all applicable invoices.

12.Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original and each of which will together constitute one and the same agreement.

13.Section 409A. It is the intent of the parties that all payments under this Agreement are either exempt from or comply with Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations issued thereunder (“Section 409A”). Notwithstanding anything in this Agreement to the contrary, any payments or benefits due hereunder, if any, that constitute non-exempt “deferred compensation” (as defined in Section 409A) that are payable by reason of your termination of employment will not be paid or provided to you until you have undergone a “separation from service” (as defined in Section 409A). If it is determined that any payments or benefits due to you hereunder would otherwise cause the application of an accelerated or additional tax under Section 409A if paid or provided to you pursuant to this Agreement during the six-month period immediately following your “separation from service” (as defined in Section 409A), such payments or benefits will instead be payable in a single lump sum on the first business day after the date that is six (6) months following such “separation from service” or, if earlier, within ten (10) business days following receipt of notice by the Company of your death. Your right to receive any installment payments under this Agreement will be treated as a right to receive a series of separate payments and, accordingly, each such installment payment will at all times be considered a separate and distinct payment as permitted under Section 409A. If you are entitled to be paid or reimbursed for any taxable expenses, and such payments or reimbursements are includable in your federal gross taxable income, the amount of such expenses reimbursable in any one calendar year will not affect the amount reimbursable in any other calendar year, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. No right to reimbursement of expenses under this Agreement will be subject to liquidation or exchange for another benefit. You will be solely responsible for all taxes and other amounts due in connection with any payment hereunder, including, without limitation, any additional taxes, interest or other amounts owed by you resulting from the application of Section 409A.
