After the Effective Time, the former holders of the Brunton Shares (other than USE) shall be entitled only to receive the USE Shares to which they are entitled under this Agreement, or to the benefit of their rights as Dissenting Shareholders. 4.2 Exchange of Old Certificates for New Certificates. a. Appointment of Exchange Agent. From and after the Effective Time until the end of the twelve-month period following the Effective Time, USE shall make available or cause to be made available to Society Investment Management and Trust Services, Denver, Colorado (the "Exchange Agent") certificates ("New Certificates") representing the USE Shares, for the Exchange Agent to deliver New Certificates to the former holders of the Brunton shares in exchange for certificates therefor ("Old Certificates"). b. Exchange Procedures. Promptly after the Effective Time, USE shall cause the Exchange Agent to mail or deliver to each person (other than any Dissenting Shareholder) who was, at the Effective Time, a holder of record of Brunton Shares a form of transmittal letter with instructions for surrender of Old Certificates in exchange for New Certificates, or for deposit of Old Certificates by Dissenting Shareholders. Upon surrender to the Exchange Agent of an Old Certificate for cancellation together with the completed transmittal letter, the holder of such Old Certificate shall be entitled to receive a New Certificate representing the USE Shares, and the Old Certificate as surrendered shall forthwith be canceled. If any New Certificate is to be issued in a name other than that in which the Old Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the person requesting such exchange shall pay any transfer or other taxes required by reason of the issuance of such New Certificate in a name other than the registered holder of the Old Certificate surrendered, or shall establish to the satisfaction of the Exchange Agent that any such taxes have been paid or are not applicable. Twelve months after the Effective Time, USE shall be entitled to cause the Exchange Agent to deliver back any unclaimed New Certificates. Any former Brunton shareholders who have not theretofore exchanged their Old Certificates for New Certificates shall thereafter look exclusively to USE only as general creditors thereof for the USE Shares to which they became entitled, subject to exchange of their Old Certificates. Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of Brunton Shares for USE Shares delivered to public officials pursuant to escheat laws. USE shall pay all expenses of the exchange of New Certificates for Old Certificates. c. Fractional Shares. No fractional USE Share shall be issued in the Exchange, and any fraction to which a former holder of Brunton Shares would otherwise be entitled, shall be rounded up to the next full USE Share if the former holder of Brunton Shares owned 10 or more thereof, and down to the next lower full USE Share if the former holder of Brunton Shares owned 9 or fewer thereof. d. Distributions with Respect to Unexchanged Shares. No dividends on USE Shares shall be paid to a former holder of Brunton Shares holding an Old Certificate, until the Old Certificate is surrendered for exchange. Subject to the effect of applicable laws, following surrender of any such Old Certificate by any holder thereof other than a Dissenting Shareholder, there shall be paid to the holder of the New Certificate issued in exchange therefor, without interest (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the USE Shares represented thereby and not paid, less any required withholding taxes, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to the time of such surrender and a payment date subsequent to the time of such surrender payable with respect to the USE Shares represented thereby, less the amount of any required withholding taxes. e. Transfers. At and after the Effective Time, there shall be no transfers of Brunton Shares on the Brunton stock transfer books, except to transfer all issued and outstanding Brunton Shares to USE as record and beneficial owner. f. No Liability. If any Old Certificate shall have been lost, stolen or destroyed, upon making of an affidavit of that fact by the person claiming such, and if required by USE the posting by such person of a bond in reasonable amount as indemnity against possible future claim against it with respect to such Old Certificate, USE shall cause the Exchange Agent to issue the USE Shares in respect thereof pursuant to this Article IV. 4.3 Dissenters' Rights. If any Brunton Dissenting Shareholder gives written notice to Brunton under WBCA Section 17- 60-1321 to seek payment of the "fair value" of his or her Brunton Shares as provided in the WBCA, Brunton shall give USE notice thereof, and USE shall have the right to participate in negotiations with respect to such demands. Only Brunton shall make any such payments, and then only from Brunton funds. Pursuant to the WBCA, a Dissenting Shareholder who fails to perfect, or loses the right to dissent, shall only be entitled to USE Shares based on the Exchange, and shall be entitled to no payment for his or her Brunton Shares.
