SUBSIDIARY GUARANTY

SUBSIDIARY GUARANTY dated as of March 12, 2010 made by The Black & Decker Corporation, a Maryland corporation (the “Guarantor”), in favor of the Administrative Agent and the Lenders (as defined in the Credit Agreement referred to below).

PRELIMINARY STATEMENT. Stanley Black & Decker, Inc. (formerly known as The Stanley Works), a Connecticut corporation (the “Company”), and the parent company of the Guarantor, is party to an Amended and Restated Credit Agreement dated as of February 27, 2008, and Amendment No. 1 thereto dated as of February 17, 2009 (such Credit Agreement, as so amended, the “Credit Agreement”; capitalized terms used herein have the meanings assigned to such terms in the Credit Agreement). The Guarantor may receive, directly or indirectly, a portion of the proceeds of the Advances under the Credit Agreement and will derive substantial direct and indirect benefits from the transactions contemplated by the Credit Agreement. It is a condition precedent to the effectiveness of Amendment No. 2 to the Credit Agreement dated as of the date hereof (the “Amendment”) and the continued making of Advances by the Lenders under the Credit Agreement from time to time that the Guarantor shall have executed and delivered this Guaranty.

NOW, THEREFORE, in consideration of the premises and in order to induce the Lenders to enter into the Amendment and to make Advances under the Credit Agreement from time to time, the Guarantor hereby agrees as follows:

SECTION 1. Guaranty; Limitation of Liability. (a) To induce the other parties to enter into the Amendment and for other valuable consideration, receipt of which is hereby acknowledged, the Guarantor hereby unconditionally and irrevocably guarantees to the Administrative Agent, each Lender and their respective successors and permitted assigns the prompt payment in full when due (whether at stated maturity, by acceleration or otherwise) of the principal of and interest on the Advances to and the Notes of each other Loan Party and all other amounts whatsoever now or hereafter payable or becoming payable by each other Loan Party under the Credit Agreement and each other Loan Document, in each case strictly in accordance with the terms thereof (collectively, the “Guaranteed Obligations”). The Guarantor hereby further agrees that if any other Loan Party shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the Guarantor will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal. This Section 1 is a continuing guaranty and is a guaranty of payment and is not merely a guaranty of collection and shall apply to all Guaranteed Obligations whenever arising.

(b) The Guarantor, and by its acceptance of this Guaranty, the Administrative Agent and each Lender, hereby confirms that it is the intention of all such Persons that this Guaranty and the obligations of the Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of any bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent

applicable to this guaranty and the obligations of the Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the Lenders and the Guarantor hereby irrevocably agree that the obligations of the Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the obligations of the Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance.

SECTION 2. Acknowledgments, Waivers and Consents. The Guarantor agrees that its obligations under this Guaranty shall be primary, absolute, irrevocable and unconditional under any and all circumstances and that the guaranty herein is made with respect to any Guaranteed Obligations now existing or in the future arising. Without limiting the foregoing, the Guarantor agrees that:

(a) The occurrence of any one or more of the following shall not affect the enforceability or effectiveness of this Guaranty in accordance with its terms or affect, limit, reduce, discharge or terminate the liability of the Guarantor, or the rights, remedies, powers and privileges of the Administrative Agent or any Lender, under this Guaranty:

(i) any modification or amendment (including by way of amendment, extension, renewal or waiver), or any acceleration or other change in the time for payment or performance of the terms of all or any part of the Guaranteed Obligations or any Loan Document, or any other agreement or instrument whatsoever relating thereto, or any modification of the Commitments;

(ii) any release, termination, waiver, abandonment, lapse or expiration, subordination or enforcement of the liability of any other guaranty of all or any part of the Guaranteed Obligations;

(iii) any application of the proceeds of any other guaranty (including the obligations of any other guarantor of all or any part of the Guaranteed Obligations) to all or any part of the Guaranteed Obligations in any such manner and to such extent as the Administrative Agent may determine;

(iv) any release of any other Person (including any other guarantor with respect to all or any part of the Guaranteed Obligations) from any personal liability with respect to all or any part of the Guaranteed Obligations;

(v) any settlement, compromise, release, liquidation or enforcement, upon such terms and in such manner as the Administrative Agent may determine or as applicable law may dictate, of all or any part of the Guaranteed Obligations or any other guaranty of (including any letter of credit issued with respect to) all or any part of the Guaranteed Obligations;

(vi) the giving of any consent to the merger or consolidation of, the sale of substantial assets by, or other restructuring or termination of the corporate existence of, any other Loan Party or any other Person or any disposition of any shares of any Loan Party;

(vii) any proceeding against any other Loan Party or any other guarantor of all or any part of the Guaranteed Obligations or any collateral provided by any other Person or the exercise of any rights, remedies, powers and privileges of the Administrative Agent and the Lenders under the Loan Documents or otherwise in such order and such manner as the Administrative Agent may determine, regardless of whether the Administrative Agent or the Lenders shall have proceeded against or exhausted any collateral, right, remedy, power or privilege before proceeding to call upon or otherwise enforce this Guaranty;

(viii) the entering into such other transactions or business dealings with any other Loan Party, any Subsidiary or affiliate thereof or any other guarantor of all or any part of the Guaranteed Obligations as the Administrative Agent or any Lender may desire; or

(ix) all or any combination of any of the actions set forth in this Section 2(a).

(b) The enforceability and effectiveness of this Guaranty and the liability of the Guarantor, and the rights, remedies, powers and privileges of the Administrative Agent and the Lenders, under this Guaranty shall not be affected, limited, reduced, discharged or terminated, and the Guarantor hereby expressly waives to the fullest extent permitted by law any defense now or in the future arising, by reason of:

(i) the illegality, invalidity or unenforceability of all or any part of the Guaranteed Obligations, any Loan Document or any other agreement or instrument whatsoever relating to all or any part of the Guaranteed Obligations;

(ii) any disability or other defense with respect to all or any part of the Guaranteed Obligations, including the effect of any statute of limitations that may bar the enforcement of all or any part of the Guaranteed Obligations or the obligations of any other guarantor of all or any part of the Guaranteed Obligations;

(iii) the illegality, invalidity or unenforceability of any security for or other guaranty (including any letter of credit) of all or any part of the Guaranteed Obligations or the lack of perfection or continuing perfection or failure of the priority of any Lien on any collateral for all or any part of the Guaranteed Obligations;

(iv) the cessation, for any cause whatsoever, of the liability of any other Loan Party or any other guarantor with respect to all or any part of the Guaranteed Obligations (other than, subject to Section 3, by reason of the full payment of all Guaranteed Obligations);

being under no obligation to take any such action notwithstanding the fact that all or any part of the Guaranteed Obligations may be due and payable and that such other Loan Party may be in default of its obligations under any Loan Document;

(vi) any counterclaim, set-off or other claim which any other Loan Party or any other guarantor of all or any part of the Guaranteed Obligations has or claims with respect to all or any part of the Guaranteed Obligations, or any counterclaim, set-off or other claim which the Guarantor may have with respect to all or any part of any obligations owed to the Guarantor by the Administrative Agent or any Lender (other than, without prejudice to Section 3, any counterclaim or other claim that the amount of the Guaranteed Obligation which is being claimed has been finally paid in full);

(vii) any failure of the Administrative Agent or any Lender or any other Person to file or enforce a claim in any bankruptcy or other proceeding with respect to any Person;

(ix) any action taken by the Administrative Agent or any Lender that is authorized under this Guaranty or by any other provision of any Loan Document or any omission to take any such action;

(x) any law, regulation, decree or order of any jurisdiction or Governmental Authority or any event affecting any term of the Guaranteed Obligations; or

(xi) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor.
