In case the Company shall grant any rights or options, other than options or rights granted pursuant to the Company's Incentive Stock Option Plan (or any similar plan it might adopt), to subscribe for, purchase or otherwise acquire Common Stock, there shall be determined the price per share for which Common Stock is issuable upon the exercise of such rights or options, such determination to be made by dividing (a) the total amount, if any, received or receivable by the Company as consideration for the granting of such rights or options, plus the minimum aggregate amount of additional consideration payable to the Company upon the exercise of such rights or options, by (b) the maximum number of shares of Common Stock of the Company issuable upon the exercise of such rights or options. If the price per share so determined shall be less than the applicable Purchase Price per share, then the granting of such rights or options shall be deemed to be an issue or sale for cash (as of the date of the granting of such rights or options) of such maximum number of shares of Common Stock at the price per share so determined, provided that, if such rights or options shall by their terms provide for an increase or increases, with the passage of time, in the amount of additional consideration payable to the Company upon the exercise thereof, the adjusted purchase price per share shall, forthwith upon any such increase becoming effective, be readjusted to reflect the same, and provided, further, that upon the expiration of such rights or options, if any thereof shall not have been exercised, the adjusted Purchase Price per share shall forthwith be readjusted and thereafter be the price which it would have been had an adjustment been made on the basis that the only shares of Common Stock so issued or sold were those issued or sold upon the exercise of such rights or options and that they were issued or sold for the consideration 10 SPECTRAN CORPORATION actually received by the Company upon such exercise, plus the consideration, if any, actually received by the Company for the granting of all such right or options, whether or not exercised. 9.

The Company will forthwith mail a copy of each such certificate to each holder of a Warrant. 11. Notices of Record Date, etc. In the event of (a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend payable out of earned surplus of the Company) or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, or (b) any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any transfer of all or substantially all the assets of the Company to or consolidation or merger of the Company with or into any other person, or (c) any voluntary or involuntary dissolution, liquidation or winding-up of the Company, or (d) any proposed issue or grant by the Company of any shares of stock of any class or any other securities, or any right or option to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities (other than (i) in connection with the Company's Incentive Stock Option Plan (or any similar plan it might adopt), or (ii) the issue of Common Stock on the exercise of the Warrants), then and in each such event the Company will mail or cause to be mailed to each holder of a Warrant a notice specifying (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, (ii) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up is to take 11 SPECTRAN CORPORATION place, and the time, if any, as of which the holder of record of Common Stock (or Other Securities) shall be entitled to exchange their shares of Common Stock (or Other Securities) for securities or other property deliverable upon such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up, and (iii) the amount and character of any stock or other securities, or rights or options with respect thereto, proposed to be issued or granted, the date of such proposed issue or grant and the persons or class of persons to whom such proposed issue or grant is to be offered or made.
