Section 17. Expenses Of Collection And Attorneys' Fees. Should this GUARANTY be referred to an attorney for collection, the GUARANTOR shall pay all of the holder's reasonable costs, fees and expenses resulting from such referral, including reasonable attorneys' fees, which the holder may incur, even though judgment has not been confessed or suit has not been filed. Section 18. Confession Of Judgment. Upon the occurrence of an EVENT OF DEFAULT, the GUARANTOR authorizes any attorney admitted to practice before any court of record in the 5 United States, or the clerk of such court, to appear on behalf of the GUARANTOR and to confess judgment in any such court against the GUARANTOR in the full amount due on this GUARANTY at such time plus an attorneys' fee equal to fifteen percent (15%) of the amount due. The GUARANTOR waives any right to notice or a hearing prior to the entry of judgment and to the benefit of any and every statute, ordinance, or rule of court which may be lawfully waived conferring upon the GUARANTOR any right or privilege of exemption, appeal, stay of execution, or supplementary proceedings, or other relief from the enforcement or immediate enforcement of a judgment or related proceedings on a judgment. The authority and power which the GUARANTOR has given for any attorney admitted to practice before any court of record in the United States, or the clerk of such court, to appear for and confess judgment against the GUARANTOR shall be a continuous authority which shall not be exhausted or extinguished by any one or more exercises or imperfect exercises thereof or by any one or more judgments entered pursuant thereto and may be exercised on one or more occasions and at such times and from time to time after default and in the same or different courts or jurisdictions as the LENDER may consider necessary or advisable. In the event that the LENDER receives, as a result of execution on a judgment confessed hereunder, attorneys' fees which exceed the actual legal fees incurred by the LENDER in connection with the enforcement of this GUARANTY, then upon full and final payment of all other sums due and owing to the LENDER in accordance with this GUARANTY and the payment to the LENDER of the actual attorneys' fees incurred by the LENDER, the LENDER shall remit such excess amount of attorneys' fees to the GUARANTOR. Section 19. Interest Rate After Judgment. If judgment is entered against the GUARANTOR on this GUARANTY, the amount of the judgment entered (which, unless applicable law specifically provides to the contrary, includes all principal, prejudgment interest, late charges, prepayment charges if any are provided for, collection expenses, attorneys' fees, and court costs) shall bear interest at the highest rate after default authorized by the LOAN DOCUMENTS as of the date of entry of the judgment to the extent permitted by applicable law. In the event any statute or rule of court specifies the rate of interest which a judgment on this GUARANTY may bear or the amount on which such interest rate may apply and such rate or amount is less than that called for in the preceding sentence absent a restriction under applicable law, the GUARANTOR: (a) agrees to pay to the order of the LENDER an amount as will equal the interest computed at the highest rate after default provided for in the LOAN DOCUMENTS which would be due on the judgment amount (which, for this purpose, shall be considered to include all principal, prejudgment interest, late charges, prepayment charges if any are provided for, collection expense fees, attorneys' fees, and court costs) less the interest due on the amount of the judgment which bears judgment interest; and (b) authorizes the confession of judgment pursuant to the confession of judgment provision of this GUARANTY if the GUARANTOR fails to make payment thereof. Section 20. Enforcement During Bankruptcy. Enforcement of this GUARANTY shall not be stayed or in any way delayed as a result of the filing of a petition under the United States Bankruptcy Code, as amended, by or against the BORROWER. Should the LENDER be required to obtain an order of the United States Bankruptcy Court to begin enforcement of this GUARANTY after the filing of a petition under the United States Bankruptcy Code, as amended, by or against the BORROWER, the GUARANTOR hereby consents to this relief and agrees to file or cause to be filed all appropriate pleadings to evidence and effectuate such consent and to enable the LENDER to obtain the relief requested. Section 21. Remedies Cumulative. All of the LENDER'S rights and remedies shall be cumulative and any failure of the LENDER to exercise any right hereunder shall not be construed 6 as a waiver of the right to exercise the same or any other right at any time, and from time to time, thereafter. Section 22. Continuing Guaranty. This GUARANTY is a continuing guaranty of all existing and future obligations of the BORROWER to the LENDER and may not be terminated by the GUARANTOR until the LOAN DOCUMENTS are terminated, in accordance with the provisions thereof, and the payment (which payment shall not be subject to challenge or contest) in full of all of the OBLIGATIONS and all of the BORROWER'S obligations and liabilities to the LENDER under the LOAN DOCUMENTS. Section 23. Reinstatement. If at any time any payment, or portion thereof, made by, or for the account of, the BORROWER or the GUARANTOR on account of any of the obligations and liabilities under any of the LOAN DOCUMENTS is set aside by any court or trustee having jurisdiction as a voidable preference, or fraudulent conveyance or must otherwise be restored or returned by the LENDER to the BORROWER or any other person or entity under any insolvency, bankruptcy or other federal and/or state laws or as a result of any dissolution, liquidation or reorganization of the BORROWER or any other person or entity, or for any other reason, the GUARANTOR hereby agrees that this GUARANTY shall continue and remain in full force and effect or be reinstated, as the case may be, all as though such payment(s) had not been made. Section 24. Rights Of Subrogation, Etc. In the event the GUARANTOR pays any sum to or for the benefit of the LENDER pursuant to this GUARANTY, the GUARANTOR may not enforce any right of contribution, indemnification, exoneration, reimbursement, subrogation or other right or remedy against the BORROWER, any other guarantor, or any collateral, whether real, personal, or mixed, securing the obligations of the BORROWER to the LENDER or the obligations of any other guarantor to the LENDER until such time as the LENDER has been paid in full and has no further claim against the BORROWER, any other guarantor, or any collateral. The GUARANTOR waives and releases any claim which the GUARANTOR hereafter may have against the LENDER if some action of the LENDER, whether intentional or negligent, impairs, destroys, or in any way adversely affects any right of contribution, indemnification, exoneration, reimbursement, subrogation, or the like which the GUARANTOR may have upon the payment of any sum to or for the benefit of the LENDER pursuant to this GUARANTY. Section 25. Subordination Of Certain Indebtedness. If the GUARANTOR advances any sums to the BORROWER or its successors or assigns or if the BORROWER or its successors or assigns shall hereafter become indebted to the GUARANTOR, such sums and indebtedness shall be subordinate in all respects to the amounts then or thereafter due and owing to the LENDER by the BORROWER. Section 26. Setoff. The LENDER shall have the right to setoff and apply against the OBLIGATIONS any sums which the GUARANTOR at any time has on deposit with the LENDER whether such deposits are general or special, time or demand, provisional or final, and the GUARANTOR hereby pledges and grants to the LENDER a security interest in all such deposits. Section 27. Renewals, Etc. This GUARANTY shall apply to all sums now or hereafter owed by the BORROWER to the LENDER and to all extensions, modifications, amendments, renewals, substitutions, and refinancings thereof. Section 28. Choice Of Law. The laws of the State of Maryland (excluding, however, conflict of law principles) shall govern and be applied to determine all issues relating to this 7 GUARANTY and the rights and obligations of the parties hereto, including the validity, construction, interpretation, and enforceability of this GUARANTY and its various provisions and the consequences and legal effect of all transactions and events which resulted in the issuance of this GUARANTY or which occurred or were to occur as a direct or indirect result of this GUARANTY having been executed. Section 29. Consent To Jurisdiction; Agreement As To Venue. The GUARANTOR irrevocably consents to the non-exclusive jurisdiction of the courts of the State of Maryland and of the United States District Court for the District of Maryland, if a basis for federal jurisdiction exists. The GUARANTOR agrees that venue shall be proper in any circuit court of the State of Maryland selected by the LENDER or in the United States District Court for the District of Maryland if a basis for federal jurisdiction exists and waives any right to object to the maintenance of a suit in any of the state or federal courts of the State of Maryland on the basis of improper venue or of inconvenience of forum. Section 30. Proofs Of Sums Due On Guaranty. In any action or proceeding brought by the LENDER to collect the sums owed on this GUARANTY, a certificate signed by an officer of the LENDER setting forth the unpaid balances of principal, and any accrued interest, default interest, attorneys' fees, and late charges owed with respect hereto shall be presumed correct and shall be admissible in evidence for the purpose of establishing the truth of what it asserts. Section 31. Actions Against Lender. Any action brought by the GUARANTOR against the LENDER which is based, directly or indirectly, on this GUARANTY or any matter in or related to this GUARANTY, including but not limited to the obligations of the BORROWER to the LENDER, the administration, collection, or enforcement thereof, shall be brought only in the courts of the State of Maryland. The GUARANTOR may not file a counterclaim against the LENDER in a suit brought by the LENDER against the GUARANTOR in a state other than the State of Maryland unless under the rules of procedure of the court in which the LENDER brought the action or the counterclaim is mandatory, and not merely permissive, and will be considered waived unless filed as a counterclaim in the action instituted by the LENDER. The GUARANTOR agrees that any forum other than the State of Maryland is an inconvenient forum and that a suit brought by the GUARANTOR against the LENDER in a court of any state other than the State of Maryland should be forthwith dismissed or transferred to a court located in the State of Maryland by that court. Section 32. Invalidity Of Any Part. If any provision or part of any provision of this GUARANTY shall for any reason be held invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions or the remaining part of any effective provisions of this GUARANTY, and this GUARANTY shall be construed as if such invalid, illegal, or unenforceable provision or part thereof had never been contained herein, but only to the extent of its invalidity, illegality, or unenforceability.
