If any holder of Investor -4- Shares has elected to participate in such contemplated Transfer, the Transferring Stockholder and each such electing holder shall be entitled to sell in the contemplated Transfer, at the same price and on the same terms, a number of Stockholder Shares equal to the product of (i) the quotient determined by dividing the percentage of Stockholder Shares owned by such Person by the aggregate percentage of Stockholder Shares owned by the Transferring Stockholder and the holders of Investor Shares participating in such sale and (ii) the number of Stockholder Shares to be sold in the contemplated Transfer.

(d) Termination of Restrictions. The restrictions on the Transfer of --------------------------- Stockholder Shares set forth in this Section 4 shall continue with respect to each Stockholder Share until the date on which such Stockholder Share has been transferred in a Public Sale or a Sale of the Company in accordance with Section 6. 5.

(b) Election. The Proposing Stockholders shall deliver written -------- notice to the Company and the Non-Proposing Stockholders setting forth in reasonable detail the terms of the proposed Sale of the Company (the "Sale ---- Notice").

If the Non-Proposing Stockholders have not ----------------------- delivered a Stockholder Offer within such 20-day period, the Proposing Stockholders shall have 180 days after the expiration of the Election Period to consummate the Sale of the Company, or during which the Company may enter into an agreement providing for such a sale, on the terms specified in the Sale Notice. If the Sale of the Company is not consummated or the Company fails to enter into such an agreement within such 180-day period, the Proposing Stockholders shall again comply with the provisions of this Section 6. If the Non-Proposing Stockholders have delivered a Stockholder Offer within the Election Period, the Non-Proposing Stockholders must (A) obtain an executed definitive and binding agreement to consummate the Stockholder Transaction and obtain binding commitments regarding the financing thereof satisfactory in all respects to the Proposing Stockholders both within 30 days after receipt by the Proposing Stockholders of the Stockholder Offer and (B) must consummate the Stockholder Transaction within 120 days after receipt by the Proposing Stockholders of the Stockholder Offer.

Upon receipt of any Put Notice, any other holder of Investor Shares - ------- may, by written notice delivered to the Company within five (5) business days after receiving such Put Notice specifying the number of Investor Shares that such holder elects to include in such Put, elect to participate in such Put, and upon delivery of such written notice each such other holder shall be deemed to be a Requesting Holder. (c) At the Put Closing, the Requesting Holders shall deliver to the Company certificates and other instruments (if any) representing the Investor Shares to be repurchased by the Company, and the Company shall deliver to the Requesting Holders the Put Price by cashier's or certified check payable to the Requesting Holders or by wire transfer of immediately available funds to an account designated by the Requesting Holders; provided that if, as the result of the payment in cash of the Put Price in accordance with this Section 7(c), there will exist an Event of Default (as defined in each of the Purchase Agreement and the Loan Agreement) and the Company shall have used its best efforts to obtain financing from an outside source for payment of the Put Price, then the Company may pay the Put Price by delivery (i) of cash (as provided above) up to the maximum portion of the Put Price, the payment of which will not result in the occurrence or existence of an Event of Default and (ii) a promissory note in a principal amount equal to that portion of the Put Price not being paid pursuant to the foregoing clause (i), payable in three successive annual installments, with the first installment due on the first anniversary of the delivery of the Put Notice, and otherwise containing terms substantially similar to the terms set forth in the Company's 12% Senior Subordinated Notes. If the Requesting Holder deliver to the Company all or any portion of the Investor Warrants in satisfaction of the sale of the Investor's Stockholder Shares hereunder, the Put Price shall be reduced by the aggregate exercise price of such portion of the Warrants. (d) The "Put Price", as of any date, of any Requesting Holder's --------- Investor Shares to be repurchased hereunder shall be determined based on a value of the Company=s common stock equal to the greater of (i) the product of 6.25, multiplied by the Company's EBITDA for the trailing -7- 12-month period (as defined in the Purchase Agreement) for its most recently completed fiscal year as reflected on the Company's audited consolidated income statement for such fiscal year, minus the Company's aggregate principal amount of, plus accrued and unpaid interest on, outstanding indebtedness as of such date minus the liquidation value of, plus accrued and unpaid dividends, if any, on, the then outstanding preferred stock of the Company, and (ii) the Market Value as of such date. The aggregate Put Price payable to each Requesting Holder shall be equal to the amount which such holder would receive with respect to the Investor Shares specified by such holder in such holder's Put Notice in the event of a Sale of the Company for an aggregate purchase price equal to the value attributable to the Company in accordance with the foregoing sentence. In calculating the Put Price, all accounting determinations shall be made in accordance with generally accepted accounting principles consistently applied.
