(c) "Public Float Target Date" shall mean the first date following the initial public offering of Common Stock on which the aggregate market value of the Common Stock held by persons other than Tiger Management Corporation ("TMC"), affiliates of TMC, The Horsham Corporation ("Horsham"), affiliates of Horsham and employees of the Corporation exceeds $150 million. 4 The "Purchase Price" means, (a) if the Liquidation occurs prior to the Conversion Date (as hereinafter defined), $13.33 per share and (b) if the Liquidation occurs after the Conversion Date, the Share Price for the applicable Conversion Level (as defined below) as set forth in the chart in Article 4.D.3(e) below.

Conversion. (a) Five business days after final determination of the Corporation's 1995 EBITDA and the Corporation's 1995 Net Income in accordance with Subsection (c) below, the Class B Common Stock and Class C Common Stock automatically shall be converted as set forth in subsection (e) below. (b) No later than March 31, 1996, the Corporation shall furnish to TMC (i) copies of the audited consolidated financial statements of the Corporation for the calendar year 1995 (the "Corporation's 1995 Financials") which are to be prepared in accordance with United States generally accepted accounting principals consistently applied ("GAAP") and accompanied by the unqualified opinion of the Corporation's auditors, and (ii) a certificate from the Corporation attested to by the Corporation's auditors calculating the Corporation's 1995 EBITDA and the Corporation's 1995 Net Income. A copy of the certificate referred to in (ii) above shall be filed in the minute book of the Corporation. (c) The "Corporation's 1995 EBITDA" shall be equal to the Corporation's earning before interest, taxes, depreciation and amortization (as determined in accordance with GAAP), as set forth in the Corporation's 1995 Financials, as adjusted as provided in this subsection (c) and the "Corporation's 1995 Net Income" shall be equal to the Corporation's net income (as determined in accordance with GAAP), as set forth in the Corporation's 1995 Financials, as adjusted as provided in this subsection (c). In calculating the Corporation's 1995 EBITDA and the Corporation's 1995 Net Income, all items of expense shall be included. Notwithstanding the foregoing, in calculating the Corporation's 1995 EBITDA and the Corporation's 1995 Net Income, (a) any write-ups or write-downs of inventory (which shall be determined based on the lower of cost or market value of the Corporation's raw materials, work in process, supplies used in operations and finished goods, determined based on a last in, first out (LIFO) basis), based on changes in the market prices of petroleum feedstocks, blendstocks and refined products, (b) any nonrecurring events which accrue profit to the Corporation (e.g., settlements of litigation), (c) any gains or losses in the Corporation's portfolio of investment securities, (d) any book loss (which does not affect cash flow) on the Corporation's diesel desulfurizer, (e) EBITDA and Net Income of any entities acquired by the Corporation after February 27, 1995 (unless a binding acquisition agreement relating thereto shall have been entered into prior to such date), and (f) any items which artificially inflate EBITDA or Net Income for calendar year 1995, shall be disregarded. In determining the "Corporation's 1995 EBITDA" and the "Corporation's 1995 Net Income" 1995 turnaround expenditures in excess of $4,000,000 shall be expensed rather than 6 capitalized, and such amounts in excess of $4,000,000 which are expensed shall not be amortized. (d) Auditors selected by TMC shall have the right to review the determination of the Corporation's 1995 EBITDA and the Corporation's 1995 Net Income (including a review of accountants' working papers). Any disputes relating to such calculation shall be finally determined by auditors selected jointly by the other two auditing firms. Each of the three auditors described in this Section shall be a "Big Six" accounting firm and the cost of its services shall be paid by the Corporation. (e) Five days after the Corporation's 1995 EBITDA and the Corporation's 1995 Net Income are finally determined as provided for in subsection (c) and (d) above (the "Conversion Date"), each share of the Class B Common Stock and the Class C Common Stock shall be subject to a mandatory conversion into the number of shares of Common Stock and the number of shares of Class A Common Stock respectively as set forth under the Applicable Conversion Level. The "Applicable Conversion Level" shall be the conversion level set forth in the chart below (EBITDA and Net Income numbers being expressed in millions of U.S. dollars) for the lower of the Corporation's 1995 EBITDA or the Corporation's 1995 Net Income (e.g., if the Corporation's 1995 EBITDA is 160 (conversion level 2) and the Corporation's 1995 Net Income is 47 (conversion level 4), the "Applicable Conversion Level" will be conversion level 2). 7 - ----------------------------------------------------------------------------------- Conversion Conversion AND Ratio Ratio If Net per share of per share of Conversion EBITDA Income Class B into Class C Share Level is: is: shares of into shares Price Common of Class A - --------------------------------------------------------------------------------- 1 less than 158 less than 32 0.0 2.0 $13.33 - --------------------------------------------------------------------------------- 2 158-169 32-38 0.4 1.6 $13.64 - --------------------------------------------------------------------------------- 3 170-181 39-46 0.8 1.2 $13.95 - --------------------------------------------------------------------------------- 4 182-193 47-53 1.2 0.8 $14.29 - --------------------------------------------------------------------------------- 5 194-205 54-60 1.6 0.4 $14.63 - --------------------------------------------------------------------------------- 6 greater than 205 greater than 60 2.0 0.0 $15.00 - --------------------------------------------------------------------------------- 4. Anti-Dilution. The Corporation shall not take any action (including, without limitation, payment of a dividend or distribution on the capital stock, subdividing or reclassifying any outstanding shares of capital stock, issuing capital stock at less than its book value, a merger or consolidation, or any other action) which may have the effect of diluting the value Class C Common Stock (or the Class A Common Stock into which the Class C Common Stock is convertible or the Common Stock into which such Class A Common Stock is convertible), except with the prior written consent of TMC (which consent shall not be unreasonably withheld so long as TMC is satisfied that appropriate anti-dilution protection and adjustments have been put into effect by the Company with respect to such capital stock). 5. Liquidation, Dissolution or Winding Up. In the event of any Liquidation prior to the Conversion Date, for purposes of distributing the Liquidation Proceeds, each share of the Class C Common Stock is to be assumed to have been automatically converted into Class A Common Stock at a ratio of one share of Class C Common Stock to two shares of Class A Common Stock and the holders of Class C Common Stock shall be entitled to share on such basis, with the holders of Common Stock and Class A Common Stock, in the Liquidation Proceeds. E. Amendment of this Article. The Corporation may not amend, alter, change or repeal in any manner adverse to the holders of the Class A Common Stock or the Class C Common Stock the rights or preferences of the holders of the Class A Common Stock or Class C Common Stock contained in this Article 4 without the consent of the holders of 95% of the Class A Common Stock or Class C Common Stock, as the case may be. 8 FOURTH: That such amendment has been duly adopted in accordance with the provisions of the General Corporation Law of the State of Delaware by the unanimous written consent of the holders of all outstanding shares entitled to vote thereon in accordance with the provisions of Section 228 of the General Corporation Law.
