Item 4.  Purpose of Transaction.

Item 4 is hereby amended to add the following:

On April 23, 2018, Sierra, HCPF, HCP, HCM, AVI, MAIM, MP, MGP, MAGP and Messrs. Manko and Wallis (collectively, the “Investor Group”) and the Issuer entered into a Cooperation Agreement (the “Cooperation Agreement”) regarding the composition of the Issuer’s Board of Directors (the “Board”) and certain other matters. The following description of the Cooperation Agreement is qualified in its entirety by reference to the Cooperation Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

Pursuant to the terms of the Cooperation Agreement, the Issuer agreed to, among other things: (i) increase the size of its Board from seven (7) to nine (9) members; (ii) appoint each of Russell D. Glass and Ira M. Lubert to the Board (collectively, the “New Directors”) with a term expiring at the Issuer’s 2018 Annual Meeting of Shareholders (the “2018 Annual Meeting”); (iii) nominate each of the New Directors and three (3) members of the Board who are on the Board prior to the execution of the Cooperation Agreement to be selected by the members of the Board who are on the Board prior to the execution of the Cooperation Agreement (the “Incumbent Slate,” and together with the New Directors, the “2018 Nominees”) for election at the 2018 Annual Meeting with a term expiring at the Issuer’s 2019 Annual Meeting of Shareholders (the “2019 Annual Meeting”), such that a total of five (5) directors are to be elected at the 2018 Annual Meeting and such that upon the certification of the voting results for the 2018 Annual Meeting, the size of the Board shall be reduced to five (5) members; (iv) recommend each of the 2018 Nominees for election as directors of the Issuer at the 2018 Annual Meeting; (v) support and solicit proxies for the election of each of the New Directors in substantially the same manner as the Issuer supports and solicits proxies for the election of each of the members of the Incumbent Slate at the 2018 Annual Meeting; (vi) appoint one of the New Directors to the Nominating and Corporate Governance Committee of the Board and appoint the other New Director to the Compensation Committee of the Board; (vii) hold the 2018 Annual meeting no later than Friday, June 22, 2018; and (viii) not increase the size of the Board beyond five (5) members until the expiration of the Standstill Period (as defined below) without the unanimous approval of the Board, subject to certain limitations.

The Cooperation Agreement also provides that if any of the New Directors (or any replacement director) is unable or unwilling to serve as a director, resigns as a director or is removed as a director of the Issuer for any reason, other than failure to be elected or re-elected, and at such time the Investor Group beneficially owns in the aggregate at least the lesser of five percent (5.0%) of the Issuer’s then outstanding shares of Common Stock, and 1,028,037 shares of Common Stock, subject to adjustment, then the Issuer and the Investor Group will work together in good faith to identify and propose a replacement director to be appointed to the Board who shall only be appointed to the Board after having been mutually agreed upon by both the Issuer and the Investor Group.

Pursuant to the terms of the Cooperation Agreement, the Investor Group has agreed that at each annual and special meeting of shareholders held during the Standstill Period, the Investor Group will (i) appear at such meeting or otherwise cause all shares of Common Stock beneficially owned by it and its respective Affiliates and Associates (as such terms are defined in Rule 12b-2 of the Exchange Act) to be counted as present thereat for purposes of establishing a quorum; (ii) vote, or cause to be voted, all shares of Common Stock beneficially owned by it and its respective Affiliates and Associates on the Issuer’s proxy card or voting instruction form in favor of (a) the directors nominated and recommended by the Board (and not in favor of any other nominees to serve on the Board), and (b) except in connection with any Opposition Matter (as defined below) or Other Voting Recommendation (as defined below), each of the shareholder proposals listed on the Issuer’s proxy card or voting instruction form in accordance with the Board’s recommendations; and (iii) not execute any proxy card or voting instruction form in respect of such shareholders’ meeting other than the proxy card and related voting instruction form being solicited by or on behalf of the Board. Pursuant to the Cooperation Agreement, in the event that Institutional Shareholder Services Inc. (“ISS”) issues a recommendation with respect to any matter (other than with respect to the election or removal of directors) that is different from the recommendation of the Board, the Investor Group shall have the right to vote its shares of Common Stock on the Issuer’s proxy card or voting instruction form in accordance with the ISS recommendation (the “Other Voting Recommendation”). Under the Cooperation Agreement, “Opposition Matter” means any of the following transactions, but only to the extent submitted by the Board to shareholders for approval: (A) the sale or transfer of all or substantially all of the Issuer’s assets in one or a series of transactions; (B) the sale or transfer of a majority of the outstanding shares of the Issuer’s Common Stock (through a merger, stock purchase, or otherwise); (C) any merger, consolidation, acquisition of control, or other business combination; (D) any tender or exchange offer; (E) any dissolution, liquidation, or reorganization; (F) any changes in the Issuer’s capital structure (but excluding any proposals relating to the adoption, amendment or continuation of any equity plans); (G) any proposals relating to the Tax Benefits Plan (as defined in the Cooperation Agreement); or (H) any other transactions that would result in a Change of Control (as defined in the Cooperation Agreement) of the Issuer. The Investor Group also irrevocably withdrew its (i) Nomination Notice delivered to the Issuer on February 23, 2018 and any and all amendments and supplements thereto and (ii) Shareholder Inspection Demand delivered to the Issuer on March 12, 2018, pursuant to Section 1508 of the Pennsylvania Business Corporation Law, as amended.

The Investor Group also agreed to certain standstill provisions from the date of the Cooperation Agreement until 11:59 p.m., Eastern Time, on the date that is the earlier of (i) ten (10) calendar days prior to the expiration of the advance notice period for the submission by shareholders of director nominations for consideration at the 2019 Annual Meeting and (ii) one hundred (100) calendar days prior to the first anniversary of the 2018 Annual Meeting (the “Standstill Period”). The standstill provisions generally prohibit the Investor Group and its Affiliates (as defined in the Cooperation Agreement) from taking specified actions during the Standstill Period with respect to the Issuer and its securities, including, among others: (i) soliciting or participating in any solicitation of proxies or written consents to vote any voting securities of the Issuer, (ii) conducting any non-binding referendum with respect to any voting securities of the Issuer; (iii) joining any other “group” for purposes of Section 13(d) of the Exchange Act or becoming party to any voting arrangement or agreement; (iv) seeking or encouraging others to submit nominations for the election or removal of directors; (v) seeking, alone or in concert with others, representation on the Board, except as expressly permitted by the Cooperation Agreement; (vi) advising, encouraging or influencing any person with respect to the voting of or disposition of any securities of the Issuer; (vii) making shareholder proposals at any annual or special meeting of shareholders; (viii) calling, or supporting another shareholder’s call of, any meeting of shareholders; (ix) initiating, encouraging or participating in any “vote no,” “withhold” or similar campaign relating to the Issuer; (x) acquiring any additional securities of the Issuer or any rights decoupled from the underlying securities of the Issuer representing in the aggregate in excess of ten percent (10%) of the shares of Common Stock then outstanding, provided that any such additional share acquisitions can only be made to the extent that the Issuer was to determine to grant the Investor Group a waiver or exemption under the Tax Benefits Plan; or (xi) publicly announce or otherwise publicly disclose an intent to propose or enter into or agree to enter into, singly or with any other person, directly or indirectly, any form of business combination or acquisition or other transaction relating to a material amount of assets or securities of the Issuer or any of its subsidiaries.
