8. Default. If default be made in the payment of the whole or any part of the debt evidenced hereby beyond any applicable notice and cure period, or if an Event of Default (as defined in the Deed of Trust) be made in the performance of any of the terms, agreements, covenants, or conditions contained herein or contained in the Guaranty, Additional Guaranty or in any Loan Document, then, in any of these events, the entire unpaid balance of the Principal Sum due hereunder, plus all accrued interest, together with all other sums evidenced hereby or secured by the Guaranty and/or Additional Guaranty, shall, at the option of the holder hereof, at once become and be due and payable, without notice to Borrower or any other person.

11. Payment of Costs. If, after any default hereunder or under the Deed of Trust, the Guaranty or the Additional Guaranty which continues beyond any applicable notice and cure period, the Holder retains an attorney with respect to any enforcement action which the Holder may be entitled to take, including but not limited to, any suit or action, which is instituted to collect any or all of the Principal Sum, any interest accrued thereon or any other sum falling due under the provisions of this Note, or if this Note is placed in the hands of an attorney for collection, the Borrower hereby agrees to pay all reasonable costs thereby incurred by the Holder, including reasonable attorneys’ fees, all of which shall be added to and become part of the debt evidenced hereby.

12. Confessed Judgment. Upon the occurrence of a default in the payment of the whole or any part of the debt evidenced hereby beyond any applicable notice and cure period, or if an Event of Default (as defined in the Deed of Trust) be made in the performance of any of the terms, agreements, covenants, or conditions contained herein or contained in the Additional Guaranty, the Deed of Trust or in any Loan Document, Borrower authorizes and empowers any attorney or any clerk of any court of record in the United States of America to appear on behalf of Borrower in any court having jurisdiction, in one or more proceedings, or before any clerk thereof or other court official, and TO CONFESS JUDGMENT AGAINST BORROWER, WITHOUT PRIOR NOTICE OR OPPORTUNITY OF BORROWER FOR PRIOR HEARING, in favor of Lender or the Holder for and in the amount of the unpaid Principal Sum, all interest accrued and unpaid thereon, all other amounts due and payable by Borrower to Lender or the Holder under the terms of this Note, court costs, expenses, and attorneys’ fees of five percent (5%) of the total amount then due hereunder. Notwithstanding the Lender’s right to the attorneys’ fees described above in connection with any confession of judgment proceeding, the Lender may only collect such actual reasonable attorneys’ fees and expenses that are incurred by its counsel in connection therewith, and upon payment of the amount of the judgment, including such actual reasonable attorneys’ fees and expenses, the judgment shall be considered satisfied. Borrower waives and releases, to the extent permitted by applicable law, the benefit of any and every statute, ordinance, rule of court and all errors and all rights of exemption, appeal, stay of execution, inquisition, other relief from the enforcement or immediate enforcement of a judgment or related proceedings on a judgment, and other rights to which Borrower may otherwise be entitled under the laws of the United States of America or of any state or possession of the United States of America now in force or which may hereafter be enacted. The authority and power to appear for and enter judgment against Borrower shall not be exhausted by one or more exercises thereof, or by any imperfect exercise thereof, and shall not be extinguished by any judgment entered pursuant thereto. Such authority and power may be exercised on one or more occasions, from time to time, in the same or different jurisdictions as often as Lender or the Holder shall deem necessary or advisable, for all of which this Note shall be sufficient authority.

13. Commercial Loan. Borrower stipulates and warrants that (a) the loan evidenced hereby is a “commercial loan” within the meaning of Section 12-101(c) of the Commercial Law Article of the Annotated Code of Maryland, and (b) all loan proceeds will be used for such commercial loan purpose.

14. Severability. If any provision (or any part of any provision) contained in this Note shall for any reason be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision (or remaining part of the affected provision) of this Note, but this Note shall be construed as if such invalid, illegal or unenforceable provision (or part thereof) had never been contained herein, but only to the extent it is invalid, illegal, or unenforceable.

15. Governing Law; Jurisdiction; Service of Process. Borrower hereby acknowledges, consents and agrees (a) that the provisions of this Note

and the rights of all parties mentioned herein shall be governed by Maryland law and interpreted and construed in accordance with such laws (excluding Maryland conflict of laws), and (b) that the United States District Court for the Northern District of Maryland, or any Maryland court of competent jurisdiction, shall have jurisdiction in any proceeding instituted to enforce this Note, and any objections to venue are hereby waived. Borrower hereby consents to process being served in any suit, action, or proceeding instituted in connection with this Note by (a) the mailing of a copy thereof by certified mail, postage prepaid, return receipt requested, to it at its address designated herein and (b) serving a copy thereof upon John H. Gurley, Esquire, the agent hereby designated and appointed by Borrower as Borrower’s agent for service of process. Borrower irrevocably agrees that such service shall be deemed in every respect to be effective service of process in any such suit, action, or proceeding. Nothing in this Note shall affect the right of Lender to serve process in any manner otherwise permitted by law and nothing in this Note will limit the right of Lender otherwise to bring proceedings against Borrower in the courts of any other appropriate jurisdiction or jurisdictions.

16. Time of the Essence. The Borrower agrees that time is strictly of the essence hereof.

17. Extensions. The Maturity Date and/or any other date by which payment is required to be made hereunder may be extended by the Holder from time to time in its sole discretion, without in any way altering or impairing the Borrower’s liability hereunder.

18. Estoppel Certificates. The Borrower agrees to furnish to the Holder at any time and from time to time, within fifteen (15) days after written request therefor, a written estoppel certificate, duly executed and acknowledged, setting forth the amount then due under this Note, and whether any claim, offset or defense then exists hereunder.

19. Remedies Cumulative. Each right, power, and remedy of Lender as provided for in this Note or any of the other Loan Documents, or now or hereafter existing under any applicable law or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power or remedy provided for in this Note or any of the other Loan Documents or now or hereafter existing under any applicable law. The exercise or beginning of the exercise by Lender of any one or more of such rights, powers, or remedies shall not preclude the simultaneous or later exercise by Lender of any or all such other rights, powers or remedies. No failure or delay by Lender to insist on the strict performance of any term, condition, covenant or agreement of this Note or any of the other Loan Documents, or to exercise any right, power or remedy consequent on a breach thereof, shall constitute a waiver of any such term, condition, covenant, or agreement or of any such breach, or preclude Lender from exercising any such right, power or remedy at a later time or times. No provision hereof may be waived or modified orally, but all such waivers or modifications shall be in writing, expressly waiving or modifying such provision and signed by the party against whom enforcement of any waiver or modification is sought.

20. Assignability. This Note may be assigned by the Lender or any subsequent Holder at any time and from time to time, and shall inure to the benefit of and shall be enforceable by the Lender and its successors and assigns and any other person to whom the Lender may grant an interest in the Borrower’s obligations to the Lender, and shall be binding and enforceable against the Borrower and the Borrower’s successors and assigns.

21. Waiver of Jury Trial. BORROWER, ON BEHALF OF ITSELF AND ITS SUCCESSORS AND ASSIGNS, WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ALL RIGHT TO TRIAL BY JURY OF ANY AND ALL CLAIMS ARISING UNDER THIS NOTE, THE DEED OF TRUST, OR ANY OTHER DOCUMENTS AND AGREEMENTS EXECUTED IN CONNECTION, DIRECTLY OR INDIRECTLY, WITH THIS LOAN TRANSACTION, AND ANY AND ALL CLAIMS ARISING UNDER COMMON LAW OR UNDER ANY STATUTE OF ANY STATE OR THE UNITED STATES OF AMERICA, WHETHER ANY SUCH CLAIMS BE NOW EXISTING OR HEREAFTER ARISING, NOW KNOWN OR UNKNOWN. IN MAKING THIS WAIVER BORROWER ACKNOWLEDGES AND AGREES THAT ANY AND ALL CLAIMS MADE BY THE HOLDER OF THIS NOTE AGAINST THE BORROWER AND ALL CLAIMS MADE BY BORROWER AGAINST THE HOLDER OF THIS NOTE SHALL BE HEARD BY A JUDGE OF A COURT OF PROPER JURISDICTION AND SHALL NOT BE HEARD BY A JURY. THIS WAIVER IS KNOWINGLY, WILLINGLY AND VOLUNTARILY MADE BY THE BORROWER, AND THE BORROWER HEREBY REPRESENTS AND WARRANTS THAT NO REPRESENTATIONS OF FACT OR OPINION HAVE BEEN MADE BY ANY INDIVIDUAL TO INDUCE THIS WAIVER OF TRIAL BY JURY OR TO IN ANY WAY MODIFY OR NULLIFY ITS EFFECT. THE BORROWER FURTHER REPRESENTS AND WARRANTS THAT IT HAS BEEN REPRESENTED IN THE SIGNING OF THIS NOTE AND IN THE MAKING OF THIS WAIVER BY INDEPENDENT LEGAL COUNSEL, SELECTED OF ITS OWN FREE WILL, AND THAT IT HAS HAD THE OPPORTUNITY TO DISCUSS THIS WAIVER WITH COUNSEL.
