Exercise. -------- (a) General. The Option may be exercised by the Participant as a whole ------- or from time to time in part by completion and delivery to PIP Funding I of an exercise notice (together with any documents specified therein) in one of several forms to be prescribed by PIP Funding I depending on whether the Participant proposes to pay the Purchase Price for the Debentures being purchased in cash or by delivery of a secured recourse note or by application of the proceeds from a simultaneous conversion of Debentures into Convertible Preferred Stock and then into Common Stock and the sale of all or a portion of such Common Stock. Upon exercise of the Option the Participant will be required to pay to PIP Funding I an amount equal to the Purchase Price (i.e., $100,000 for each $105,264 principal amount of Option Debentures being purchased) plus interest, if any (which payment of interest may be in cash or by a short-term secured recourse note). If requested several days in advance of exercise of the Option, PIP Funding I will endeavor to ascertain and advise the Participant of the approximate amount of any interest to be paid upon such exercise and the next date on which the Option may be exercised without payment of interest. The communications in the preceding sentence may be oral or in writing. (b) Delivery of Notes. If payment of the Purchase Price and/or any ----------------- interest is to be made by delivery of a secured recourse note or notes, the Purchased Option Debentures will be retained by PIP Funding I as security for the payment of the notes. The notes shall be in such forms as shall be prescribed by PIP Funding I and shall require a pledge of such Debentures and the delivery to PIP Funding I of such other documents as it may require in connection therewith. (c) Schedule. Upon each exercise of the Option, the Participant will -------- be required to submit to PIP Funding I the Participant's copy of this -6- Investment Option Agreement for notation by PIP Funding I on the schedule annexed hereto of the principal amount of Option Debentures purchased, the date of exercise and the remaining principal amount of Option Debentures for which the Option may be exercised. When the Option has been fully exercised, the Participant's copy of this Investment Option Agreement will be marked cancelled. Upon any repurchase of the Option, the Participant will be required to deliver the Participant's copy of this Investment Option Agreement to PIP Funding I for similar marking. 7. Conversion. Conversion of Debentures acquired by a Participant ---------- upon exercise of the Option shall be effected by completion and delivery to the Company of a conversion notice (together with the documents specified therein) in one of several forms to be prescribed by the Company depending on the manner of payment of the Purchase Price and the disposition to be made of the Convertible Preferred Stock issuable upon conversion of the Debentures and the Common Stock issuable upon conversion of the Convertible Preferred Stock. 8. Subordinated Guarantee of the Company. The Company unconditionally ------------------------------------- and irrevocably guarantees that if PIP Funding I does not repay the investment Option Amount (including any premium with respect thereto) in connection with any repurchase of the Option required herein, the Company shall pay such amount as if the Company instead of PIP Funding I were the primary obligor for such amount under this Investment Option Agreement; provided, however, that this -------- ------- obligation of the Company is subordinated to the extent and in the manner provided in the Debentures as originally issued to PIP Funding I with regard to the Company's obligations under such Debentures, to the prior payment in full of all "Senior Debt" of the Company, as such term is defined in such Debentures. 9.

Upon exercise of the Option by the Participant, the purchased Debentures may be pledged, assigned, hypothecated or transferred, subject to compliance with applicable securities laws and delivery to the Company of a legal opinion satisfactory to the Company with respect to such compliance (except that the purchased Debentures may be pledged as security for any secured recourse notes delivered to PIP Funding I without the delivery of a legal opinion); provided, -------- however, that, concurrently with such sale, pledge, assignment, hypothecation or ------- transfer, the Participant repays the outstanding balance of any secured recourse notes delivered by such Participant or the Company approves the assignment of the Participant's secured recourse notes to the transferee. Thereafter the Debentures shall be convertible only by the transferee. (c) Tax Withholding. The Company and its subsidiaries shall have the --------------- right to require the Participant to remit to the Company, prior to the delivery of any certificate or certificates for Debentures, Convertible Preferred Stock or Common Stock or the payment of any money or other property, an amount sufficient to satisfy any Federal, state and/or local tax withholding requirements. (d) Amendment. This Investment Option Agreement may not be modified, --------- amended or waived in any manner except by an instrument in writing signed by each of the parties hereto.
