NOW, THEREFORE, in consideration of the foregoing and the mutual agreements set forth in the Agreement and this Amendment, the parties hereto, intending to be legally bound, hereby agree as follows:

1. Amendments to the Agreement. The Agreement is hereby amended as follows:

a.Section 1(c). The definition of “Acquiring Person” in Section 1(c) of the Agreement is hereby amended and restated in its entirety as follows:

“(c) “Acquiring Person” shall mean any Person who or that, together with all Affiliates and Associates of such Person, without the prior written approval of the Board, shall be the Beneficial Owner of 12.5% or more of the Common Shares then outstanding; provided, however, the term “Acquiring Person” shall be deemed to exclude: (i) the Company; (ii) any Subsidiary of the Company; (iii) any employee benefit or compensation plan of the Company or of any Subsidiary of the Company; (iv) any Person holding Common Shares for or

pursuant to the terms of any such employee benefit plan or compensation plan of the Company or any Subsidiary of the Company, but solely to the extent such Common Shares are held for or pursuant to the terms of any such plan; (v) a Passive Institutional Investor (but only if such Person remains a “Passive Institutional Investor” in accordance with the definition thereof or divests sufficient Common Shares after ceasing to be a Passive Institutional Investor as contemplated by the definition thereof (and following such divestment, such Person shall no longer be a Passive Institutional Investor)) and (vi) an Exempt Person (but only if such Person remains an “Exempt Person” in accordance with the definition thereof). Notwithstanding the foregoing: (A) any Person who or that, together with its Affiliates and Associates, (x) is, as of the time of the first public announcement of the declaration of the Rights dividend, the Beneficial Owner of 12.5% (or, in the case of a Person that would otherwise be a Passive Institutional Investor but for such ownership, 20%) or more of the Common Shares outstanding and (y) continuously maintains its level of Beneficial Ownership at or above 12.5% or 20%, as applicable, of the Common Shares outstanding from and after the time of such first public announcement shall not be deemed to be an “Acquiring Person” until such time after the first public announcement of the declaration of the Rights dividend that any such Person shall (I) become the Beneficial Owner of one or more additional Common Shares (other than by the declaration or payment of any dividend on the Common Shares payable in Common Shares) and (II) then beneficially own 12.5% (or, in the case of a Person that would otherwise be a Passive Institutional Investor but for such ownership, 20%) or more of the Common Shares then outstanding (it being understood that (x) this clause (A) shall grandfather the security or instrument underlying such Beneficial Ownership only in the type and form as of the time of the first public announcement of the declaration of the Rights dividend and shall not grandfather any subsequent change, modification, swap or exchange of such security or instrument underlying such Beneficial Ownership into a different type or form of security or instrument (unless such change, modification, swap or exchange is contemplated explicitly by the terms of such security or instrument (e.g., as would be the case for options to purchase shares of Common Stock, in which case the shares of Common Stock purchased upon the exercise of such options would be grandfathered)) and (y) cash-settled swap or exchange contracts for differences in the price of shares of Common Stock or other equity securities of the Company shall not be grandfathered under this Agreement); and (B) no Person shall become an “Acquiring Person” (x) as the result of an acquisition of Common Shares by the Company that, by reducing the number of shares outstanding, increases the proportionate number of shares beneficially owned by such Person to 12.5% (20% in the case of a Person who would otherwise be a Passive Institutional Investor but for such acquisition of Common Shares by the Company) or more of the Common Shares then outstanding (provided, however, that if a Person shall become the Beneficial Owner of 12.5% (20% in the case of a Person that would otherwise be a Passive Institutional Investor but for such acquisition) or more of the Common Shares then outstanding by reason of share purchases by the Company and, following written notice from, or public disclosure by, the Company of such share purchases by the Company, shall become the Beneficial Owner of one or more additional Common Shares (other than by the declaration or payment of any dividend on the Common Shares payable in Common Shares) without the prior written approval of the Board and shall then be the Beneficial Owner of 12.5% (20% in the case of a Person that would otherwise be a Passive Institutional Investor but for such ownership) or more of the Common Shares then outstanding, then such Person shall be deemed to be an “Acquiring Person”) or (y) if the Board determines in good faith that a Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this Section 1(c), has become such inadvertently (including, in the

case of an Exempt Person, because such Person inadvertently failed to comply with the requirements of such definition), and such Person does not, with such Person’s Affiliates and Associates, become the Beneficial Owner of any additional Common Shares after learning of or having been informed of such Person becoming (save for this clause) an Acquiring Person, and, only if requested by the Company, such Person divests, as promptly as practicable (as determined in good faith by the Board), following receipt of written notice from the Company of such event, Beneficial Ownership of a sufficient number of Common Shares so that such Person would no longer be an Acquiring Person, as defined pursuant to the foregoing provisions of this Section 1(c), then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement; provided, however, that if such Person shall again (I) become the Beneficial Owner of 12.5% (20% in the case of a Person who would otherwise be a Passive Institutional Investor but for such ownership) or more of the Common Shares then outstanding or (II) fail to comply with the requirements to constitute an Exempt Person, such Person shall be deemed an “Acquiring Person,” subject to the exceptions set forth in this Section 1(c).”

b.Section 1. The definition of “Final Expiration Date” in Section 1(w) of the Agreement is hereby amended and restated in its entirety as follows:

“(w) “Final Expiration Date” shall mean April 17, 2025.”
