Guarantor further agrees to pay all reasonable out-of-pocket costs and expenses, including, without limitation, all court costs and reasonable attorneys' and paralegals' fees paid or actually incurred by the Agent or the Lenders, in endeavoring to collect all or any part of Borrowers' Liabilities from, or in prosecuting any action against, Guarantor or any other guarantor of all or any part of Borrowers' Liabilities. All amounts payable by Guarantor under this Guaranty shall be payable upon demand by the Agent. Guarantor hereby agrees that, except as hereinafter provided, his obligations under this Guaranty shall be unconditional, irrespective of (i) the validity or enforceability of Borrowers' Liabilities or any part thereof, or of any promissory note or other document evidencing all or any part of Borrowers' Liabilities, (ii) the absence of any attempt to collect Borrowers' Liabilities from Borrowers or any other guarantor or other action to enforce the same, (iii) the waiver or consent by the Agent or the Lenders with respect to any provision of any instrument evidencing Borrowers' Liabilities, or any part thereof, or any other agreement heretofore, now or hereafter executed by any Borrower and delivered to the Agent or the Lenders, (iv) failure by the Agent to take any steps to perfect and maintain its security interest in, or to preserve its rights to, any security or collateral for Borrowers' Liabilities, (v) the institution of any proceeding under Chapter 11 of Title 11 of the United States Code (11 U.S.C.

Guarantor is delivering to the Agent herewith Guarantor's personal financial statement for the year ending December 31, 1994 (the "Financial Statement"). Guarantor acknowledges and agrees that the Agent and the Lenders have relied on, and have been justified in their reliance on, the truth and completeness of each of the items contained in the Financial Statement in determining to enter into the Fourth Amendment, to consummate the transactions contemplated thereby and to accept this Guaranty on an unsecured basis from the Guarantor. In connection, therewith, the Guarantor hereby represents and warrants in favor of the Agent and the Lenders, and hereby covenants to each of them, that: (i) the Financial Statement is true and complete in all material respects and does not omit the statement of any facts material to the financial condition of the Guarantor; (ii) no event or development has occurred since the effective date of the Financial Statement which has had or is reasonably likely to have a material adverse effect on Guarantor's condition, financial or otherwise, business, assets, liabilities or prospects (a "Material Adverse Effect"); and (iii) so long as this Guaranty remains in effect, Guarantor shall promptly advise the Agent in writing of the occurrence of any event or condition which has had or is reasonably likely to have a Material Adverse Effect.

The Agent shall have The exclusive right to determine The time and manner of application of any payments or credits, whether received from Borrowers or any other source, and such determination shall be binding on Guarantor. All such payments and credits may be applied, reversed and reapplied, in whole or in part, to any of Borrowers' Liabilities as the Agent shall determine in its sole discretion without affecting the validity or enforceability of this Guaranty (unless otherwise required pursuant to the Loan Agreement). Guarantor hereby assumes responsibility for keeping himself informed of the Financial condition of Borrowers, and any and all endorsers and/or other guarantors of any instrument or document evidencing all or any part of Borrowers' Liabilities and of all other circumstances bearing upon the risk of nonpayment of Borrowers' Liabilities or any part thereof that diligent inquiry would reveal and Guarantor hereby agrees that neither the Agent nor the Lenders shall have any duty to advise Guarantor of information known to any of them regarding such condition or any such circumstances or to undertake any investigation not a part of their respective regular business routines. If the Agent or any Lender, in its sole discretion, undertakes at any time or from time to time to provide any such information to the Guarantor, neither the Agent or such Lender, as the case may be, shall be under any obligation to update any such information or to provide any such information to Guarantor on any subsequent occasion. Guarantor consents and agrees that neither the Agent nor the Lenders shall be under any obligation to marshall any assets in favor of Guarantor or against or in payment of any or all of Borrowers' Liabilities. Guarantor further agrees that, to the extent that any -3- Borrower makes a payment or payments to the Agent or the Lenders, or the Agent or the Lenders receive any proceeds of collateral, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to such Borrower, its estate, trustee, receiver or any other party, including, without limitation, Guarantor, under any bankruptcy law, state or federal law, common law or equitable theory, then to the extent of such payment or repayment, Borrowers' Liabilities or the part thereof which has been paid, reduced or satisfied by such amount, and Guarantor's obligations hereunder with respect to such portion of Borrowers' Liabilities, shall be reinstated and continued in full force and effect as of the date such initial payment, reduction or satisfaction occurred. Guarantor hereby waives any and all claims (including without limitation any claim for reimbursement, contribution or subrogation) of Guarantor against Borrowers, any endorser or any other guarantor of all or any part of Borrowers' Liabilities, or against any of Borrowers' properties, arising by reason of any payment by Guarantor to the Agent or the Lenders pursuant to the provisions hereof. Each Lender may, without notice to anyone, sell or assign Borrowers' Liabilities or any part thereof, or grant participations therein, and in any such event each and every immediate or remote assignee or holder of, or participant in, all or any of Borrowers' Liabilities shall have the right to enforce this Guaranty, by suit or otherwise for the benefit of such assignee, holder, or participant, as fully as if herein by name specifically given such right. This Guaranty shall be binding upon Guarantor and upon the heirs, successors (including without limitation, any receiver, trustee or debtor in possession of or for Guarantor) and assigns, of Guarantor and shall inure to the benefit of the Agent, the Lenders and their respective successors and assigns.

In case of any such discontinuance, this Guaranty and the obligations of Guarantor and his heirs, successors or assigns shall remain in full force and effect with respect to all of Borrowers' Liabilities incurred prior to the receipt by the Agent of written notice of such discontinuance.

As used herein, the term "Stock Pledge" shall mean: (i) the execution and delivery to the Agent, for the ratable benefit of the Lenders, by each member of the Smith -4- Group (each such member, for purposes of the Stock Pledge, a "Pledgor"), of a stock pledge agreement in substantially the form of Annex 1 attached hereto; (ii) the delivery to the Agent of a stock certificate or certificates, duly authorized and appropriately completed, evidencing such Pledgor's unrestricted ownership, beneficially and of record, of such Smith Securities, together with financing statements on form UCC-1, executed by such Pledgor as debtor and listing the Agent, for the ratable benefit of the Lenders, as Secured Party, describing the collateral as such shares of Smith Securities, together with the proceeds thereof, which financing statements shall be suitable for recordation in all appropriate jurisdictions; (iii) the execution and delivery by such Pledgor to the Agent of appropriate stock powers in blank; (iv) the execution or delivery by such Pledgor to the Agent of all other agreements, documents and instruments which the Agent shall determine, in its commercially reasonable judgment, to be necessary or desirable in connection with such Pledgor's pledge and assignment of the Smith Securities, as hereinabove described and (iv) the pledge and assignment to the Agent, as hereinabove described, of not less than 800,000 shares, in the aggregate, of Smith Securities, which shares shall constitute not less than thirteen percent (13%) of the Smith Securities.
