For purposes of this paragraph 2.2 any material breach by Puritan-Bennett of its obligations hereunder which are not cured after thirty days written notice given to Puritan-Bennett by you, may, at your option, be treated by you as a termination of your employment without cause. 2.3 You shall have the option to terminate your employment hereunder in the event that: (i) Puritan-Bennett shall merge or consolidate with any other corporation(s) 3 Mr. Bert Dole April 25, 1980 Page 3 wherein Puritan-Bennett shall not be the surviving corporation; (ii) Puritan-Bennett shall liquidate or dissolve or shall sell, transfer or otherwise dispose of substantially all of its properties, business and assets; or (iii) any other corporation, person, entity or group thereof acting in concert shall directly or indirectly acquire control of voting stock of Puritan-Bennett representing 50% or more of all voting stock of Puritan-Bennett, provided that appointment as a proxy for purposes of voting shares at any meeting of stockholders shall not be considered to be a direct or indirect acquisition of control of the shares subject to such proxy. Upon occurrence of any of the foregoing events and you shall have a period of ninety days thereafter to exercise the termination option herein provided by giving written notice of such exercise to Puritan-Bennett.
