In the event of an involuntary termination due to a Corporate Transaction prior to the Award Payment Date or the Eligibility Date, a Participant may be considered for an Award subject to the other terms and conditions of the Plan and with any arrangements with a third party involved in the Corporate Transaction.

In the event of any Corporate Transaction, the Shares of restricted stock not otherwise vested shall automatically vest in full.

Corporate Transaction. In the event of a Corporate Transaction (including without limitation a Change of Control), the Administrator may, in its discretion, # provide for the assumption or substitution of, or adjustment to, each outstanding Award by the successor corporation or a parent or subsidiary of the successor corporation (the “Successor Corporation”); # accelerate the vesting and termination of outstanding Awards, in whole or in part, so that such Awards can be exercised before or otherwise in connection with the closing or completion of the transaction or event but then terminate; and/or # provide for termination of Awards as a result of the Corporate Transaction on such terms and conditions as it deems appropriate, including providing for the cancellation of Awards for a cash payment to the Participant. The Board or Committee need not provide for identical treatment of each outstanding Award.

Merger, Consolidation or Similar Corporate Transaction. In the event of a merger or consolidation of the Company with or into another corporation or a sale of substantially all of the stock of the Company (a “Corporate Transaction”), unless the Option is assumed by the surviving company in the Corporate Transaction (the “Surviving Company”) or replaced with an equivalent award granted by the Surviving Company in substitution for the Option, the Committee shall cancel any portion of the Option that is not vested and nonforfeitable as of the consummation of such Corporate Transaction (unless the vesting of the Option is accelerated by the Committee in its sole discretion or pursuant to a written agreement between the Company and the Grantee) and with respect to any vested and nonforfeitable portion of the Option, the Committee may either # allow the Grantee to exercise the Option within a reasonable period prior to the consummation of the Corporate Transaction and cancel any portion of the Option that remains unexercised upon consummation of the Corporate Transaction, or # cancel the Option in exchange for a payment (in cash, or in securities or other property) in an amount equal to the amount that the Grantee would have received (net of the Exercise Price with respect to the Option) if such vested Option was settled or distributed or such vested Option was exercised immediately prior to the consummation of the Corporate Transaction. Notwithstanding the foregoing, if an Option is not assumed by the Surviving Company or replaced with an equivalent award issued by the Surviving Company and the Exercise Price with respect to the Option exceeds the Fair Market Value of the shares of Common Stock immediately prior to the consummation of the Corporation Transaction, the Option shall be cancelled without any payment to the Grantee.

Except as provided otherwise in an individual Award Letter, in the event of a Corporate Transaction if permitted by the applicable laws:

Awards to Corporate participants will be based on their Guideline Incentive (eligible salary multiplied by the applicable guideline percentage) multiplied by the Corporate Final Performance Index. The Corporate Final Performance Index shall be based on the consolidated financial performance of the Company including Graybar Corporate, districts, zones and all subsidiaries as determined from time to time in accordance with guidelines adopted by the Board.

Each party shall be responsible for its own costs and expenses incurred in connection with the preparation, negotiation and delivery of this Agreement and the Transaction Documents, including but not limited to attorneys’ and accountants’ fees and expenses; except that in no event shall any of such costs or expenses be borne by or charged to the Company.

Fundamental Transaction. If, at any time while this Warrant is outstanding, # the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, # the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, # any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, # the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization, or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or # the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, the Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

Fundamental Transaction. If, at any time while this Note is outstanding, # [[Organization A:Organization]], directly or indirectly, in one or more related transactions effects any merger or consolidation of [[Organization A:Organization]] with or into another Person, # [[Organization A:Organization]] (and all of its Subsidiaries, taken as a whole), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, # any, direct or indirect, purchase offer, tender offer or exchange offer (whether by [[Organization A:Organization]] or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, # [[Organization A:Organization]], directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or # [[Organization A:Organization]], directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent conversion of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in [Section 4(c)] on the conversion of this Note), the number of shares of Common Stock of the successor or acquiring corporation or of [[Organization A:Organization]], if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in [Section 4(c)] on the conversion of this Note). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of Common Stock in such Fundamental Transaction, and [[Organization A:Organization]] shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash, or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following such Fundamental Transaction. [[Organization A:Organization]] shall cause any successor entity in a Fundamental Transaction in which [[Organization A:Organization]] is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of [[Organization A:Organization]] under this Note and the other Transaction Documents (as defined in the Purchase Agreement) in accordance with the provisions of this [Section 5(a)] pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Note, deliver to the Holder in exchange for this Note a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Note which is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon conversion of this Note (without regard to any limitations on the conversion of this Note) prior to such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such conversion price being for the purpose of protecting the economic value of this Note immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of [[Organization A:Organization]] and shall assume all of the obligations of [[Organization A:Organization]] under this Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as [[Organization A:Organization]] herein.
