(f) Fractional Shares. No fraction of a share of Synergy Common Stock shall be issued by virtue of the Merger, but in lieu thereof, each holder of shares of Callisto Common Stock and Callisto Preferred Stock who would otherwise be entitled to a fraction of a share of Synergy Common Stock (after aggregating all fractional shares of Synergy Common Stock that otherwise would be received by such holder) shall be automatically converted into the right to receive one full additional share of Synergy Common Stock.

1.7 Share Issuance Process.

(a) Synergy to Provide Common Stock. Promptly following the Effective Time, Synergy shall make available for delivery in accordance with this Article I, the shares of Synergy Common Stock issuable pursuant to Section 1.6 hereof.

All shares of Callisto Common Stock and Callisto Preferred Stock shall be deemed to no longer be issued and outstanding as of the Effective Time, subject to rights of holders of Dissenting Shares as set forth below.

(b) Transfers of Ownership. If certificates representing shares of Synergy Common Stock are to be issued in a name other than that reflected on Callisto’s stock register, it will be a condition of the issuance thereof that the persons requesting such exchange will have paid to Synergy or any agent designated by it, any transfer or other taxes required by reason of the issuance of certificates representing shares of Synergy Common Stock in any name other than that of the registered holder of Callisto Common Stock, Callisto Preferred Stock, or established to the satisfaction of Synergy or any agent designated by it that such tax has been paid or is not payable.

(c) No Liability. Notwithstanding anything to the contrary in this Section 1.7, neither Synergy nor any other party hereto shall be liable to a holder of shares of Synergy Common Stock, Callisto Common Stock or Callisto Preferred Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

1.8 No Further Ownership Rights in Callisto Common Stock. All shares of Synergy Common Stock issued in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Callisto Common Stock and Callisto Preferred Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Callisto Common Stock and Callisto Preferred Stock which were outstanding immediately prior to the Effective Time. If, at any time following the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I.

1.9 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, Synergy shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, certificates representing the shares of Synergy Common Stock into which the shares of Callisto Common Stock or Callisto Preferred Stock represented by such Certificates were converted pursuant to Section 1.6 hereof.

1.10 Tax Consequences. It is intended by the parties hereto that the Merger shall constitute a reorganization within the meaning of Section 368 of the Code. The parties hereto adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Income Tax Regulations. None of the parties hereto shall take any action that would be reasonably expected to cause the Merger to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code.

1.11 Dissenting Shares. Notwithstanding anything contained herein, the shares of Callisto Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Callisto Stockholders who did not vote in favor of the Merger and who comply with all of the relevant provisions of Section 262 of Delaware Law (the “Dissenting Shares”) shall not be converted into Synergy Common Stock, unless and until such Callisto Common Stockholders shall have waived in writing or failed to perfect or shall have effectively withdrawn or lost their rights to appraisal under Section 262 of Delaware Law; and any such Callisto Common Stockholder shall have only such rights in respect of the Dissenting Shares owned by them as are provided by Delaware Law. If any such Callisto Common Stockholder shall have waived in writing or failed to perfect or shall have effectively withdrawn or lost such right, such Callisto Common Stockholder’s Dissenting Shares shall thereupon be deemed to have been converted into and to have become exchangeable, as of the Effective Time, for Synergy Common Stock without any interest thereon. Callisto will promptly comply with its obligations under Section 262 of the Delaware Law and will give Synergy prompt notice of any demands and withdrawals of such demands received by Callisto for appraisals of Dissenting Shares.

1.12 Taking of Necessary Action; Further Action. If, at any time following the Effective Time, any further action is necessary or desirable to carry out the purposes and intent of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Callisto, the officers and directors of Callisto shall take all such lawful and necessary action.

1.13 Callisto Statements Regarding Synergy. The parties acknowledge that Callisto filed consolidated financial statements that include the financial results of Synergy; however the intent of this Agreement is for Callisto to provide representations and warranties on all information in its possession other than information specific to Synergy that it would obtain from Synergy. Therefore, all references throughout this Agreement to “Callisto,” “Callisto and it subsidiaries,” “Callisto or its subsidiaries” and/or “Callisto nor any of its subsidiaries” shall be references to Callisto and all of its subsidiaries other than Synergy and any references to predecessor shall be references to all predecessors of Callisto other than Synergy and representations regarding financial statements shall be representations solely with regard to information that does not include information provided by Synergy and shall solely be information pertaining to Callisto and its subsidiaries other than Synergy.
