Representations and Warranties. Each of Guarantors represents and warrants to Agent, each of Lenders and Issuing Bank that: (a) Authority, Enforceability and Conflicts. Such Guarantor has full power and authority to enter into this Agreement and all other Credit Documents executed by it in con- nection with this Agreement, to execute and deliver all documents and instruments required hereunder and thereunder, and to incur and perform the obligations provided for herein and therein, all of which have been duly authorized by all necessary action, and no consent or approval of any person, including, without limita- tion, any Governmental Authority, which has not been obtained, is required as a condition to the validity or enforceability hereof or thereof. This Agreement and all other Credit Documents exe- cuted by such Guarantor in connection with this Agreement have been duly executed and delivered by such Guarantor and consti- tute, and will continue to constitute, the valid and legally binding obligations of such Guarantor and are, and will continue to be, fully enforceable against such Guarantor in accordance with their terms, subject to bankruptcy and other laws affecting the rights of creditors generally. The execution, delivery and performance by such Guarantor of this Agreement and all other Credit Documents executed by such Guarantor in connection with this Agreement, will not violate any Legal Requirement or any material contract, agreement, instrument or other document or obligation to which such Guarantor is a party or by which such Guarantor, or any of its property, is bound.

Such Guarantor is a cor- poration duly incorporated, legally existing and in good standing under the laws of the state of its incorporation, has the power to own its property and to conduct its business, and is duly qualified to do business, and is in good standing, in each juris- diction where the failure to be so qualified or in good standing would have a material adverse effect on its ability to own, lease or operate its property or conduct its business.

Such Guarantor is not insolvent (as defined in Section 101(32) of the United States Bankruptcy Code), unable to pay its debts as they mature or engaged in business for which its property is an unreasonably small capital.

Such Guarantor has duly obtained and now holds in full force and effect all licenses, permits, certifica- tions, approvals and the like which it is required by any Legal Requirement to hold and the failure to hold which could reason- ably be expected to have a Material Adverse Effect. Such Guaran- tor is not in violation of, or, to the knowledge and belief of such Guarantor, under investigation with respect to or threatened to be charged with or given notice of a violation of, any Legal Requirement, including, without limitation, ERISA, any Environ- mental Laws or any law, rule, regulation or order relating to the collection, payment and deposit of employees' income, unemploy- ment or social security taxes or of sales, use or excise taxes, or relating to occupational safety and health, or relating to public health, except for any non-compliance which could not reasonably be expected to result in the imposition of a Lien upon any of the property, assets or revenues of such Guarantor or any Other Obligor or expose such Guarantor or any Other Obligor to potential liability in excess of One Hundred Thousand Dollars ($100,000.00).

None of the proceeds of any Revolving Credit Loans or other credit extended pursuant to the Credit Agreement will be used, directly or indirectly, for the purpose of purchasing or carrying any "margin stock" (as defined in Regulation U of the Board of Governors of the United States Federal Reserve System) or for the purpose of maintaining, reduc- ing or retiring any Indebtedness which was originally incurred to purchase or carry any such margin stock or for any other purpose which might constitute any of the transactions contemplated by the Credit Agreement a "purpose credit" within the meaning of such Regulation U or any other regulation of such Board of Gover- nors. 4. Waiver of Trial by Jury. Each of Guarantors agrees and, by their acceptance hereof, each of Agent, Lenders and Issu- ing Bank agrees, that any action, suit or proceeding involving any claim, counterclaim or cross-claim arising out of or in any way relating, directly or indirectly, to this Guaranty, the Cred- it Agreement or the other Credit Documents, or any liabilities, rights or interests of such Guarantor, Agent, any Lender, Issuing Bank or any other person arising out of or in any way relating, directly or indirectly, to any of the foregoing, shall be tried by a court and not by a jury. To the fullest extent permitted by applicable law, each of Guarantors waives, and by their accep- tance hereof, each of Agent, Lenders and Issuing Bank waives, any right to trial by jury in any such action, suit or proceeding, with the understanding and agreement that this waiver constitutes a waiver of trial by jury of all claims, counterclaims and cross- claims against all parties to such actions, suits or proceedings, including claims, counterclaims and cross-claims against parties who are not parties to this Guaranty, the Credit Agreement or the other Credit Documents.

Each of Guar- antors agrees that service of process in any such suit, action or proceeding may be effected by mailing a copy thereof by regis- tered or certified mail (or any substantially similar form of mail), postage prepaid, to such Guarantor at the Guarantor Ad- dress (or at such other address as such Guarantor may specify to Agent, Lenders and Issuing Bank); provided, however, that nothing contained herein shall affect the right to effect service of process in any other manner permitted by law. 12. Successors and Invalidity. This Guaranty shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, and each reference in this Guaranty to any of the parties hereto shall be deemed to include the successors and assigns of such party, including, in the case of each Guarantor, the debtor, debtor in possession or trustee in any case under any chapter of the United States Bank- ruptcy Code in which such Guarantor is debtor. Each of Guaran- tors acknowledges and agrees that, subject to applicable law and agreements, any of Lenders or Issuing Bank may at any time, in its discretion, assign, transfer or pledge to any person, or grant to any person a security interest in, this Guaranty, the Credit Agreement, any of the other Credit Documents or any of its rights hereunder or thereunder. Subject to applicable law and agreements, any of Lenders or Issuing Bank may sell, in such amounts, upon such terms and to such persons as it may determine, participations in its interests under this Guaranty, the Credit Agreement and/or any of the other Credit Documents. If any term, provision or condition, or any part thereof, of this Guaranty shall for any reason be found or held invalid or unenforceable by any court or governmental agency, such invalidity or unenforceab- ility shall not affect the remainder of such term, provision or condition, nor any other term, provision or condition, and this Guaranty shall survive and be construed as if such invalid or unenforceable term, provision or condition had not been contained herein; provided, however, that if any rate of interest provided under this Guaranty does or shall exceed the maximum interest rate which any Guarantor is permitted by law to agree to pay, then such rate of interest shall immediately be deemed to be reduced to such maximum rate and all previous payments of inter- est in excess of the maximum rate shall be deemed to have been payments in reduction of amounts bearing interest and not of interest. 13. Survival and Merger. All representations, warran- ties, covenants and agreements of each of Guarantors contained herein shall survive the execution and delivery of this Guaranty. This Guaranty contains the entire agreement of the parties with respect to the matters covered and the transactions contemplated hereby, and no agreement, statement or promise made by any Guar- antor, Agent, any Lender or Issuing Bank, or by any of their employees, officers, agents or attorneys, which is not contained herein, shall be valid or binding. 14.
