ADJUSTMENTS IN EVENT OF CHANGES IN CAPITALIZATION 7.1 In the event that a dividend shall be declared upon the Shares of the Company payable in Shares, the number of Shares then subject to any Option outstanding under the Plan and the number of Shares reserved for Options pursuant to the Plan but not yet subject to Options shall be adjusted by adding to each such Share the number of Shares which would be distributable in respect thereof if such Shares had been outstanding on the date fixed for determining the shareholders of the Company entitled to receive such Share dividend. 7.2 In the event that a dividend shall be declared upon the Shares of the Company payable in an equity security of the Company other than the Shares, each Option outstanding under the Plan and the number and type of securities issuable under the Plan shall be changed so that thereafter there shall be issuable upon the exercise of Options then outstanding or thereafter granted, in addition to Shares, such number of such other equity security that would have been distributable in respect of Shares subject to outstanding Options or issuable under the Plan had such Shares been outstanding on the date fixed for determining the shareholders of the Company entitled to receive such equity security dividend. 7.3 In the event that a dividend shall be declared upon Shares (or other securities that, with the Shares, comprise a Unit) of the Company payable in cash or other property (other than Shares or other equity securities of the Company) and the aggregate amount of the cash or Book Value of the property payable to shareholders pursuant to such dividend exceeds 10% of the Company's total assets on a consolidated basis, the Option exercise price for each Share (or Unit, if applicable) subject to an Option shall be reduced on the date following the payment date of such dividend by the aggregate amount of cash and the Fair Market Value of any other property payable with respect to each outstanding Share pursuant to such dividend. 7.4 In the event that the outstanding Shares shall be changed into or exchanged for a different number or kind of shares or other securities of the Company or of another entity, whether through reorganization, recapitalization, split-up, combination of shares, merger, consolidation or otherwise, then there shall be substituted for each Share subject to any outstanding Option and for each Share reserved for Options pursuant to the Plan but not yet subject to Options the number and kind of shares or other securities into which each outstanding Share shall have been so changed or for which each such share shall have been exchanged. 7.5 In the case of any substitution or adjustment as provided for in subsections 7.1, 7.2 or 7.4 hereof, the Option price set forth in each outstanding Option for each Share covered thereby prior to such substitution or adjustment will be the Option price for all Shares or other securities which shall have been substituted for such Share or to which such Share shall have been adjusted pursuant to such subsections. 4 7.6 In the case of any adjustment provided for in subsection 7.2 hereof, the Option may thereafter only be exercisable as to Units and the Option exercise price for each Unit will be the aggregate of the Option exercise price for the Shares included within the Unit. 7.7 No adjustment or substitution provided for in this Section 7 shall require the Company to sell or issue a fraction of a Share or other equity security, and the total substitution or adjustment with respect to each outstanding Option shall be limited accordingly. Upon any adjustment made pursuant to this Section, the Company will, upon request, deliver to the Option holder or to such person's Successor a certificate of its Chief Financial Officer setting forth, with respect to such Option, the Option price thereafter in effect and the number and kind of Shares or other securities thereafter purchasable thereunder. 8. EXERCISE OF RIGHTS UNDER OPTIONS 8.1 A person entitled to exercise an Option may do so by delivery of a written notice to that effect specifying the number of Shares with respect to which the Option is being exercised and any other information the Company may prescribe. 8.2 The notice of exercise shall be accompanied by payment in full of the purchase price for any Shares to be purchased, with such payment being made in cash or cash equivalents or in Pre-Owned Shares having a Fair Market Value at that time equivalent to the purchase price of the Shares or Units to be purchased, or a combination thereof. 8.3 In lieu of delivery of a stock certificate or certificates evidencing Shares tendered by the Grantee in payment of the purchase price in exercising an Option, the Grantee may furnish a notarized statement executed by the Grantee, in such form as prescribed by the Company, as payment for all or a portion of the purchase price for Shares or Units to be purchased. The statement shall recite the number of Shares or Units being purchased by the Grantee pursuant to the Option and the number of Pre-Owned Shares owned by the Grantee which otherwise could be freely delivered as payment of the purchase price by the Grantee based on their Fair Market Value at that time. The Grantee will then be issued a certificate(s) for (a) new Shares equal to the number of Shares acquired by the Grantee hereunder upon exercise of the Option, less the number of Pre-Owned Shares owned by the Grantee and described in the notarized statement, and (b) if applicable, other securities comprising the Units as to which the exercise relates. 8.4 No Shares or other securities shall be issued upon exercise of an Option until full payment has been made therefor. 8.5 Upon exercise of an Option but before a distribution of Shares or other securities in satisfaction thereof, the Grantee may request in writing that the Shares or other securities to be issued in satisfaction of the Option exercise be issued in the name of the Grantee and another person as joint tenants with right of survivorship or as tenants in common. 8.6 All notices or requests to the Company provided for herein shall be delivered to the Secretary of the Company. 9. EFFECTIVE DATE OF THE PLAN AND DURATION 9.1 The Plan shall become effective on the date upon which the Company files a definitive Proxy Statement with the Securities and Exchange Commission respecting a Special Meeting of Company shareholders, called for the purpose of considering and voting upon a proposal to amend the Company's Articles of Incorporation to change the Company's name to Lab Holdings, Inc. 5 9.2 The Plan shall remain in effect until all Options have been exercised in accordance herewith, but no Options may be granted under the Plan after September 15, 2007. The provisions of any Option may be amended at any time prior to the end of its Term in accordance with the Plan. 10.

POSTPONEMENT OR NON-EXERCISE The Company shall not be required to issue any certificate or certificates for Shares or other securities upon the exercise of an Option granted under the Plan prior to (i) the obtaining of any approval from any governmental agency which the Company shall, in its sole discretion, determine to be necessary or advisable, (ii) the taking of any action in order to comply with restrictions or regulations incident to the maintenance of a public market for its Shares or other securities, if any; and (iii) the completion of any registration or other qualification of such Shares or other securities, if any, under any state or Federal law or rulings or regulations of any governmental body which the Company shall, in its sole discretion, determine to be necessary or advisable. The Company shall not be obligated by virtue of the terms and conditions of any Option or any provisions of the Plan to recognize the exercise of an Option or to sell or issue Shares or other securities in violation of the Securities Act or the law of any government having jurisdiction thereof.
