15. Standard of Care. The powers conferred on the Secured Party hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers.

and/or appraisal which the Borrower Parties now have or may at any time in the future have under any applicable law. The Borrower Parties agree that, to the extent notice of sale shall be required by law, at least ten days’ notice to the Borrower Parties of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. The Borrower Parties hereby waive any claims against the Secured Party arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Secured Party accepts the first offer received and does not offer such Collateral to more than one offeree.

(b) Lockbox.

(i) At any time after the occurrence and during the continuance of an Event of Default, the Borrower Parties shall cooperate with the Secured Party to establish the Lockbox and Cash Collateral Account (each as defined below), under the sole dominion and control of the Secured Party (to the extent permitted by applicable law), into which monies, checks, notes, drafts or other payment for or proceeds of the Collateral shall be paid as set forth in clause (ii) below.

(ii) If an Event of Default shall have occurred and be continuing, the Borrower Parties shall direct all Account Debtors to make payments on the Borrower Parties’ Accounts directly into a lockbox established by the Borrower Parties with an institution acceptable to the Secured Party and over which the Secured Party shall have sole control and authority (to the extent permitted by applicable law) pursuant to documentation in form and substance satisfactory to the Secured Party (the “Lockbox”). Thereafter, if any monies, checks, notes, drafts or other payment for or proceeds of the Collateral shall come into the possession or under the control of the Borrower Parties, the Borrower Parties shall hold same in trust for Secured Party, and the Borrower Parties shall remit or cause the same to be remitted, in kind, to Secured Party or to any agent or agents appointed by Secured Party for that purpose, and such monies, checks, notes, drafts or other payment for or proceeds of the Collateral shall be credited to the Cash Collateral Account, unless the Secured Party shall otherwise elect. Following the occurrence and during the continuance of an Event of Default, the Secured Party may, in its sole discretion, take control of and endorse the Borrower Parties’ name(s) to any of the items of payment or proceeds described in this Section 16. For the purposes of this section, the Borrower Parties irrevocably, hereby make, constitute and appoint the Secured Party, and all persons designated by the Secured Party for that purpose, as the Borrower Parties’ true and lawful attorney and agent-in-fact to take any such actions following the occurrence and during the continuance of an Event of Default. All such items of payment or proceeds received through the Lockbox or directly from the Borrower Parties during the continuance of an Event of Default shall, unless the Secured Party shall otherwise elect, be deposited into a cash collateral account maintained with an institution acceptable to the Secured Party (the “Cash Collateral Account”) over which the Secured Party has sole control and authority (to the extent permitted by applicable law) and shall be applied by the Secured Party to the Secured Obligations.

(iii) The Borrower Parties shall execute all documents requested by the Secured Party with respect to the Cash Collateral Account and the Lockbox and agrees to pay the Secured Party promptly upon demand for any and all fees, costs and expenses which the Secured Party reasonably incurs or that the relevant third party institution customarily charges in connection with the opening and maintaining of the Cash Collateral Account and the Lockbox and depositing for collection by the Secured Party any monies, checks, notes, drafts or other items of payment received and/or delivered on account of the Secured Obligations.

The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

17. No Marshalling. The Secured Party has no obligation to, and the Borrower Parties waive any right they may have to require the Secured Party to, marshal any assets in favor of the Borrower Parties, or against or in payment of any of the Secured Obligations.

18. Sales on Credit. If the Secured Party sells any of the Collateral upon credit, the Borrower Parties will be credited only with payments actually made by the purchaser, received by the Secured Party and applied to the Secured Obligations. In the event that the purchaser fails to pay for the Collateral, the Secured Party may resell the Collateral and the Secured Obligations will be credited with the proceeds of such sale.

19. Deficiency Judgments. If the proceeds of any sale or other disposition of the Collateral are insufficient to pay all the Secured Obligations, the Borrower Parties shall be liable for the deficiency and the reasonable fees of any attorneys employed by the Secured Party to collect such deficiency. If it is determined by an authority of competent jurisdiction that a disposition by the Secured Party did not occur in a commercially reasonable manner, the Secured Party may obtain a deficiency from the Borrower Parties for the difference between the amount of the Secured Obligations foreclosed and the amount that a commercially reasonable sale would have yielded.

20. Retention of Collateral. The Secured Party will not be considered to have offered to retain the Collateral in satisfaction of the Secured Obligations unless the Secured Party has entered into a written agreement with the Borrower Parties to that effect.

21. Application of Proceeds. During the continuance of an Event of Default, all proceeds received by the Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied by the Secured Party, unless otherwise required by law, to the Secured Obligations in any manner that the Secured Party, in its sole discretion, may determine until all Secured Obligations are paid in full, with the excess, if any, remitted to the Borrower Parties.

22. Continuing Security Interest. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the indefeasible payment in full of the Secured Obligations, (b) be binding upon the Borrower Parties, their respective successors and assigns and (c) inure, together with the rights and remedies hereunder, to the benefit of the Secured Party and its successors, transferees and assigns. Upon the indefeasible payment in full of all Secured Obligations, the security interest granted hereby shall automatically terminate and all rights to the Collateral shall immediately revert to the Borrower Parties.

23. Amendments; No Waiver. No amendment, modification, termination or waiver of any provision of this Agreement, and no consent to any departure by the Borrower Parties or the Secured Party therefrom, shall in any event be effective unless the same shall be in writing and signed by the Secured Party and the Borrower Parties in a document which is clearly identified as an amendment to this Agreement. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. No other act, including but not limited to a failure to exercise or a delay in exercising any right, power or privilege hereunder, on the part of the Secured Party shall be deemed to be a waiver of such right, power or privilege or an acquiescence of any default or Event of Default.

24. Notices. All notices provided for herein shall be sent to the addresses and in the manner set forth in the Note.

11

25. Severability. In case any provision in or obligation under this Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

26. Headings. Section and subsection headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose or be given any substantive effect.

27. Governing Law; Terms. This Agreement is being delivered in and shall be deemed to be a contract governed by the laws of the State of Florida and shall be interpreted and the rights and obligations of the parties hereunder enforced in accordance with the internal laws of that state without regard to the principles of conflicts of laws providing for the application of the laws of another jurisdiction.

28. Submission to Jurisdiction; Service of Process.

(e) AGREES THAT THE SECURED PARTY RETAINS THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST THE BORROWER PARTIES IN THE COURTS OF ANY OTHER JURISDICTION.

29. Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE.

31. Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document.
