Joint disclosure: these amounts are not allocated separately to each reporting owner.

10b5-1 filing: Not disclosed

Ownership: Indirect · By: Managed Accounts of Levin Capital Strategies, L.P.

Disclosed balance after: 11,247,392

F1 · security: This Form 4 is filed jointly by Levin Capital Strategies, L.P. ("LCS"), Levin Capital Strategies GP, LLC ("LCS GP"), Bi-Directional Disequilibrium Master Fund, Ltd. ("BDD")(formerly known as Levin Capital Trilogy Master Fund, Ltd.), LCS, LLC ("LCSL"), Levcap Alternative Fund, L.P. ("Levcap"), LCS Event Partners, LLC ("LCSEP"), Safinia Partners, L.P. ("Safinia"), LCS L/S, LLC ("LCSLS"), and John A. Levin (collectively, the "Reporting Persons"). The Reporting Persons are passive investors in the Issuer and are voluntarily filing this Form 4 as a result of acquiring over 20% of the Issuer's outstanding shares of Common Stock. The Reporting Persons have not acquired the shares with a purpose or effect of changing or influencing control of the Issuer.

F2 · security: Pursuant to Rule 16a-1(a)(4) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this filing shall not be construed as an admission that the Reporting Persons are, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owners of any of the securities reported herein under Section 16 or otherwise. Each of the Reporting Persons specifically disclaims beneficial ownership of the securities reported herein that are not directly owned by such Reporting Person, except to the extent of their pecuniary interest therein.

F10 · price: The price reported is a weighted average price. The reported shares were purchased in multiple transactions at prices ranging from $5.59 to $5.60. The Reporting Persons undertake to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the range set forth in this footnote 10.

F11 · balance_after: Change in amount of securities reported is due to an inadvertent accounting error.

F3 · ownership.nature: Shares held in certain separately managed accounts (the "Managed Accounts"). LCS, as the investment manager to the Managed Accounts, may be deemed to beneficially own such shares. LCS does not have a reportable pecuniary interest under Section 16a-1(a)(2) of the Exchange Act in the shares held in the Managed Accounts, as LCS receives an asset-based management fee for serving as investment manager to the Managed Accounts, except that with respect to 127,460 shares held in the Managed Accounts, LCS receives a performance-based incentive fee. The performance-based incentive fee LCS receives also does not constitute a reportable pecuniary interest under Section 16a-1(a)(2) of the Exchange Act, as such fee is based on the performance of the overall account, over a period of one year or more, and the shares of the Issuer held in such accounts constitute no more than 10% of the market value thereof.

F4 · ownership.nature: For the reasons set forth in footnote 3, none of LCS GP, BDD, LCSL, Levcap, LCSEP, Safinia, LCSLS and Mr. Levin have a reportable pecuniary interest in the shares held in the Managed Accounts.

("Safinia"), LCS L/S, LLC ("LCSLS"), and John A. Levin (collectively, the "Reporting Persons"). The Reporting Persons are passive investors in the Issuer and are voluntarily filing this Form 4 as a result of acquiring over 20% of the Issuer's outstanding shares of Common Stock. The Reporting Persons have not acquired the shares with a purpose or effect of changing or influencing control of the Issuer.

F2 · security: Pursuant to Rule 16a-1(a)(4) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this filing shall not be construed as an admission that the Reporting Persons are, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owners of any of the securities reported herein under Section 16 or otherwise. Each of the Reporting Persons specifically disclaims beneficial ownership of the securities reported herein that are not directly owned by such Reporting Person, except to the extent of their pecuniary interest therein.

F3 · ownership.nature: Shares held in certain separately managed accounts (the "Managed Accounts"). LCS, as the investment manager to the Managed Accounts, may be deemed to beneficially own such shares. LCS does not have a reportable pecuniary interest under Section 16a-1(a)(2) of the Exchange Act in the shares held in the Managed Accounts, as LCS receives an asset-based management fee for serving as investment manager to the Managed Accounts, except that with respect to 127,460 shares held in the Managed Accounts, LCS receives a performance-based incentive fee. The performance-based incentive fee LCS receives also does not constitute a reportable pecuniary interest under Section 16a-1(a)(2) of the Exchange Act, as such fee is based on the performance of the overall account, over a period of one year or more, and the shares of the Issuer held in such accounts constitute no more than 10% of the market value thereof.

F4 · ownership.nature: For the reasons set forth in footnote 3, none of LCS GP, BDD, LCSL, Levcap, LCSEP, Safinia, LCSLS and Mr. Levin have a reportable pecuniary interest in the shares held in the Managed Accounts.
