To further secure to Lender the prompt full and faithful payment and performance of Borrower’s Liabilities and the prompt, full and complete performance by Borrower of each of its covenants and duties under this Loan Agreement and the Other Agreements, Borrower grants to Lender, a valid, first priority continuing security interest in and lien upon all of the following (except as to assets or property with Permitted Liens, upon which a lien which may be other than a first priority lien is granted), whether now owned or hereafter acquired and wherever located:

Borrower shall make appropriate entries upon its financial statements and its books and records disclosing Lender’s security interest in the Collateral.

Borrower hereby further agrees that, except as expressly permitted herein including with respect to Permitted Liens, Borrower shall not hereafter grant a security interest in or pledge any of its Intellectual Property to any other party.

5.2 Further Assurances. Borrower shall execute and/or deliver to Lender, at any time and from time to time hereafter at the request of Lender, all agreements, instruments, UCC financing statements (or other required perfection instruments), documents and other written matter (hereinafter individually and/or collectively, referred to as “Additional Documentation”) that Lender reasonably may request, in a form and substance reasonably acceptable to Lender, to perfect and maintain Lender’s perfected security interest in the Collateral and to consummate the transactions contemplated in or by this Loan Agreement and the Other Agreements. Borrower, irrevocably, (a) hereby makes, constitutes and appoints Lender (and all Persons designated by Lender for that purpose) as Borrower’s true and lawful attorney (and agent-in-fact) to sign the name of Borrower on the Additional Documentation and to deliver the Additional Documentation to such Persons as Lender, in its sole and absolute discretion, may elect, (b) authorizes completion and filing of any such Additional Documentation by Lender or its agents, whether paper or electronic, (c) hereby ratifies and confirms the completion and filing of Additional Documentation by Lender or its agent, paper or electronic, occurring prior to the date hereof, and (d) declares that Borrower has the present intention to authenticate and process any such Additional Documentation, whether paper or electronic, and whether or not completed and filed by Lender or its agents before or after the date hereof.

5.3 Inspection of Collateral. Lender (by any of its officers, employees and/or agents) shall have the right, at any time or times during Borrower’s usual business hours, to inspect the Collateral and all related records (and the premises upon which it is located) and to verify the amount and condition of or any other and all financial records and matters whether or not relating to the Collateral. During the continuance of an Event of Default, all costs, fees and expenses incurred by Lender, or for which Lender has become obligated, in connection with such inspection and/or verification shall be payable by Borrower to Lender. Borrower agrees to use its best efforts to cause its employees and agents to cooperate with Lender in all inspections.

5.4 Controlled Accounts; Proceeds of Collateral. (a) Borrower shall deliver, or cause to be delivered to Lender the Account Control Agreement; provided, however, that Lender will not exercise its right to control amounts in a Controlled Account unless an Event of Default hereunder has occurred and is continuing.

(b) All proceeds arising from the disposition of any Collateral by Borrower shall be deposited in a Controlled Account within one Business Day after receipt by Borrower. Nothing in this Section limits the restrictions on disposition of Collateral set forth elsewhere in this Loan Agreement.

5.5 Third Party Claims. Lender, in its sole and absolute discretion, without waiving or releasing any obligation, liability or duty of Borrower under this Loan Agreement or the Other Agreements or any Event of Default, may (but shall be under no obligation to) at any time or times hereafter, pay, acquire and/or accept an assignment of any security interest, lien, encumbrance or claim asserted (other than Permitted Liens) by any Person against the Collateral. All sums paid by Lender in respect thereof and all costs, fees and expenses, including reasonable

attorneys’ fees, court costs, expenses and other charges relating thereto incurred by Lender on account thereof shall be payable by Borrower to Lender.

5.6 Insurance. Borrower shall at all times throughout the term of this Loan Agreement and any extension hereof procure and maintain at its own expense the following minimum insurance coverages which shall be provided by insurance carriers with an AM Best rating of A, Class C or as otherwise acceptable to Lender and with such deductibles and exclusions as approved by Lender: (1) All risk property damage insurance covering the Collateral which shall include but not be limited to fire and extended coverage and where applicable mechanical breakdown and electrical malfunction, and which shall be written in amount not less than the greater of (x) the outstanding loan balance or (y) the current replacement cost; and, (2) Commercial general liability insurance which may include excess liability insurance written on occurrence basis with a limit of not less than $2,000,000, and (3) Workers’ compensation insurance in accordance with statutory limits and employers’ liability coverage which may include excess liability in an amount not less than $2,000,000.

Any insurance carried and maintained in accordance with this Loan Agreement by Borrower shall be endorsed to provide that: (i) Lender shall be additional insured and loss payee with respect to the property insurance described in subsection (1) of the prior paragraph (and such insurance shall provide that the interest of Lender shall not be invalidated by any act or neglect of Lender, Borrower or other person), and Lender shall be an additional insured with respect to the liability insurance described in subsection (2) of the prior paragraph; and (ii) The insurers thereunder waive all rights of subrogation against Lender, any right of setoff and counterclaim and any other right to deduction due to outstanding premiums, whether by attachment or otherwise; and (iii) Such insurance shall be primary without right of contribution of any other insurance carried by or on behalf of Lender; and (iv) Inasmuch as such policies are written to cover more than one insured, all terms, conditions, insuring agreements and endorsements (other than the limits of liability) shall operate in the same manner as if there were a separate policy covering each insured; and (v) If such insurance is canceled for any reason whatsoever, including nonpayment of premium, or any substantial change is made in the coverage that affects the interests of Lender, such cancellation or change shall not be effective as to Lender until thirty (30) days after receipt by Lender of written notice sent by registered mail from such insurer of such cancellation or change; providing, however, that such thirty (30) day period shall be reduced to ten (10) days in the case where cancellation results from the nonpayment of premiums. Borrower, irrevocably, appoints Lender as Borrower’s true and lawful attorney (and agent-in fact) for the purpose of making, settling and adjusting claims under such policies, endorsing the name of Borrower on any check, draft, instrument or other item of payment for the proceeds of such policies and for making all determinations and decisions with respect to such policies, and such appointment will be immediately effective upon the occurrence of an Event of Default hereunder.

On or before the initial funding by Lender hereunder, and at each policy anniversary date, Borrower shall arrange to furnish Lender with appropriate Certificates of Insurance. Such Certificates of Insurance shall be executed by each insurer or by an authorized representative of each insurer, and shall identify insurers, the type of insurance, the insurance limits and the policy term and shall specifically list the special endorsements (i) through (v) above.

In case of the failure to procure or maintain such insurance, Lender shall have the right, but not the obligation, to obtain such insurance and any premium paid by Lender shall be immediately due and payable by Borrower to Lender. The maintenance of any policy or policies of insurance pursuant to this Section shall not limit any obligation or liability of Borrower pursuant to any other Sections or provisions of this Loan Agreement.

5.7 Charges on Collateral. Borrower shall not permit any Charges (other than Permitted Liens) to arise, or to remain, and Borrower shall pay promptly when due, and discharge, such Charges. In the event Borrower, at any time or times hereafter, shall fail to pay such Charges when due or to obtain such discharges, Borrower shall so advise Lender thereof in writing. Lender may, without waiving or releasing any obligation or liability of Borrower hereunder or Event of Default, in its sole and absolute discretion, at any time or times thereafter, make such payment, or any part thereof, or obtain such discharge and take any other action with respect thereto which Lender deems advisable. All sums so paid by Lender and any expenses, including reasonable attorneys’ fees, court costs, expenses and other charges relating thereto, shall be payable by Borrower to Lender upon demand.

5.8 UCC Filing Authorization. Borrower hereby authorizes Lender and its counsel and other representatives to file, at any time on or after the date hereof, Uniform Commercial Code financing statements and continuation statements, and amendments to financing statements, in any jurisdictions and with any filing offices as Lender may reasonably determine, in its sole discretion, are necessary or advisable to perfect the security interests granted to Lender hereunder and under the Other Agreements. Such financing statements may describe the Collateral in the same manner as described herein or therein or may contain an indication or description of Collateral that describes such property in any other manner as Lender may reasonably determine is necessary or advisable to ensure the

perfection of the security interest in the Collateral.

5.9 Accounts. So long as no Event of Default has occurred and is continuing, subject to Section 7.4 hereof, Borrower may settle, adjust or compromise any claim, offset, counterclaim or dispute with any Account Debtor. At any time that an Event of Default has occurred and is continuing, Lender may, at its option, notify Borrower that Lender intends to have the exclusive right to settle, adjust or compromise any claim, offset, counterclaim or dispute with Account Debtors or grant any credits, discounts or allowances and on and after such notice from Lender to Borrower, Lender shall have such exclusive right.

Borrower shall provide written notice of any events or circumstances which would give rise to an Event of Default under this Section 8.1 promptly (but in no event more than two (2) Business Days) after becoming aware of such events or circumstances. Failure of Borrower to give such notice promptly shall constitute an Event of Default hereunder.

8.2 Lender’s Rights and Remedies. Upon an Event of Default under Section 8.1(f), without notice by Lender to, or demand by Lender of, Borrower, all of Borrower’s Liabilities shall be automatically accelerated and shall be due and payable forthwith and any other commitments to provide any financing hereunder shall automatically terminate, and upon any other Event of Default, without notice by Lender, to or demand by Lender of, Borrower, Lender may accelerate all of Borrower’s Liabilities and same shall be due and payable forthwith and/or Lender may terminate any other commitments to provide any financing hereunder. Lender may, in its sole and absolute discretion: (a) exercise any one or more of the rights and remedies accruing to a Lender under the Uniform Commercial Code or other applicable law of the relevant state or states or other applicable jurisdiction, and in equity, and under any other instrument or agreement now or in the future entered into between Lender and Borrower, including under this Loan Agreement and the Other Agreements; (b) enter, with or without process of law and without breach of the peace, any premises where the Collateral or the books and records of Borrower related thereto is or may be located, and without charge or liability to Lender therefor seize and remove the Collateral (and copies of Borrower’s books and records relating to the Collateral) from said premises and/or remain upon said premises and use the same (together with said books and records) for the purpose of collecting, preparing and disposing of the Collateral; (c) sell, lease, license or otherwise dispose of the Collateral or any part thereof by one or more contracts at one or more public or private sales for cash or credit, provided, however, that Borrower shall be credited with the net proceeds of such sale(s) only when such proceeds are actually received by Lender; and (d) require Borrower to assemble the Collateral and make it available to Lender at a place or places to be designated by Lender which is reasonably convenient to Lender and Borrower.

In addition, at any time an Event of Default has occurred and is continuing, Lender may, in its discretion, enforce the rights of Borrower against any Account Debtor, secondary obligor or other obligor in respect of any of the Accounts. Without limiting the generality of the foregoing, at any time or times that an Event of Default has occurred and is continuing, Lender may, in its discretion, at such time or times (1) notify any or all Account Debtors, secondary obligors or other obligors in respect thereof that the Accounts have been assigned to Lender and that Lender has a security interest therein and Lender may direct any or all accounts debtors, secondary obligors and other obligors to make payment of Accounts directly to Lender, (2) extend the time of payment of, compromise, settle or adjust for cash, credit, return of merchandise or otherwise, and upon any terms or conditions, any and all Accounts or other obligations included in the Collateral and thereby discharge or release the account debtor or any secondary obligors or other obligors in respect thereof without affecting any of Borrower’s Liabilities, (3) demand, collect or enforce payment of any Accounts or such other obligations, but without any duty to do so, and Lender

shall not be liable for any failure to collect or enforce the payment thereof nor for the negligence of its agents or attorneys with respect thereto and (4) take whatever other action Lender may deem necessary or desirable for the protection of its interests. At any time that an Event of Default has occurred and is continuing, at Lender’s request, all invoices and statements sent to any Account Debtor shall state that the Accounts and such other obligations have been assigned to Lender and are payable directly and only to Lender and Borrower shall deliver to Lender such originals of documents evidencing the sale and delivery of goods or the performance of services giving rise to any Accounts as Lender may require.

All of Lender’s rights and remedies under this Loan Agreement and the Other Agreements are cumulative and non-exclusive. Exercise or partial exercise by Lender of one or more of its rights or remedies shall not be deemed an election, nor bar Lender from subsequent exercise or partial exercise of any other rights or remedies. Lender agrees to give notice of any sale to Borrower at least ten (10) days prior to any public sale or at least ten (10) days before the time after which any private sale may be held. Borrower agrees that Lender may purchase any such Collateral (including by way of credit bid), and may postpone or adjourn any such sale from time to time by an announcement at the time and place of sale or by announcement at the time and place of such postponed or adjourned sale, without being required to give a new notice of sale. Borrower agrees that Lender has no obligation to preserve rights against prior parties to the Collateral.

8.3 Power of Attorney. Upon the occurrence of any Event of Default, without limiting Lender’s other rights and remedies, Borrower grants to Lender an irrevocable power of attorney coupled with an interest (in addition to such other powers of attorney granted to Lender elsewhere in this Loan Agreement), authorizing and permitting Lender at any time, at its option, but without obligation, with or without notice to Borrower, and at Borrower’s expense, to execute on behalf of Borrower any Additional Documentation, or such other instruments or documents as may be reasonably necessary in order to exercise a right of Borrower or Lender, including but not limited to the execution of any proof of claim in bankruptcy, any notice of lien, claim of mechanic’s or other lien, or assignment or satisfaction of mechanic’s or other lien, or to take control in any manner of any cash or non-cash proceeds of Collateral and take any action or pay any sum required of Borrower pursuant to this Loan Agreement and any Other Agreement. In no event shall Lender’s rights under the foregoing power of attorney or any of Lender’s other rights under this Loan Agreement be deemed to indicate that Lender is in control of the business, management or properties of Borrower.

Payment may be made (i) in cash or by certified or official bank check, payable to the order of the Company, (ii) by cancellation by the Holder of indebtedness or other obligations of the Company to the Holder, or (iii) by a combination of the consideration described in sub-clauses (i) and (ii) above. Notwithstanding the foregoing, in the event that the Company undertakes undergoes a sale or merger transaction, then (A) if the Fair Market Value (as defined in Section 3(d) below) of one share of Common Stock is greater than the Exercise Price in effect on such date, then this Warrant shall be deemed automatically exercised pursuant to Section 3(d) below or (B) if the Fair Market Value of one Share is less than the Exercise Price in effect on such date, then this Warrant shall automatically terminate and be of no further force and effect.

(c) This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the Warrant Shares shall be treated for all purposes as the holder of record of such Warrant Shares as of the close of business on such date. As promptly as practicable on or after such date and in any event within ten (10) days thereafter, the Company at its expense shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the number of shares issuable upon such exercise. In the event that this Warrant is exercised in part, the Company at its expense will execute and deliver a new Warrant of like tenor exercisable for the number of shares for which this Warrant may then be exercised.

(d) Net Issue Exercise. Notwithstanding any provisions herein to the contrary, if the Fair Market Value of one share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of making payment of the consideration provided for in Section 3(a) above upon the exercise of all or any part of this Warrant, the Holder may surrender this Warrant at the principal office of the Company, together with the duly executed Notice of Exercise Form and, if the date of exercise is prior to the Initial Public Offering, the

C-2

duly executed Shareholders Agreement, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:


X =		Y (A - B)
		A


	X =	the number of shares of Common Stock to be issued to the Holder upon exercise

	Y =	the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised (at the date of such calculation)

	A =	the Fair Market Value of one share of the Company’s Common Stock (at the date of such calculation)

	B =	the Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the term “Fair Market Value” shall mean (i) if the principal market for the Common Stock is The NASDAQ Stock Market or any other national securities exchange, the last sales price of the Common Stock on such day as reported by such exchange or market, or on a consolidated tape reflecting transactions on such exchange or market, (ii) if the principal market for the Common Stock is not a national securities exchange or The NASDAQ Stock Market and the Common Stock is quoted on the National Association of Securities Dealers Automated Quotations System, the mean between the closing bid and the closing asked prices for the Common Stock on such day as quoted on such System or (iii) if the Common Stock is not quoted on the National Association of Securities Dealers Automated Quotations System, the mean between the highest bid and lowest asked prices for the Common Stock on such day as reported by Pink Sheets LLC; provided, however, that if none of (i), (ii) or (iii) above is applicable, or if no trades have been made or no quotes are available for such day, the Fair Market Value of the Common Stock shall be reasonably determined, in good faith, by the Board of Directors of the Company.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. In lieu of any fractional share to which the Holder would otherwise be entitled, the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction.

5. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

6. Rights of Shareholders. Subject to Sections 12, 14 and 16 of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of Common Stock or

C-3

any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised as provided herein.

7. Transfer of Warrant.

(a) Warrant Register. The Company will maintain a register (the “Warrant Register”) containing the names and addresses of the Holder or Holders. Any Holder of this Warrant or any portion thereof may change his or her address as shown on the Warrant Register by written notice to the Company, requesting such change. Any notice or written communication required or permitted to be given to the Holder may be delivered or given by mail to such Holder as shown on the Warrant Register and at the address shown on the Warrant Register. Until this Warrant is transferred on the Warrant Register of the Company, the Company may treat the Holder as shown on the Warrant Register as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the contrary.

(b) Warrant Agent. The Company may, by written notice to the Holder, appoint an agent for the purpose of maintaining the Warrant Register referred to in Section 7(a) above, issuing the Common Stock or other securities then issuable upon the exercise of this Warrant, exchanging this Warrant, replacing this Warrant, or any or all of the foregoing. Thereafter, any such registration, issuance, exchange, or replacement, as the case may be, shall be made at the office of such agent.

(i) The Holder hereby acknowledges that neither this Warrant nor the Warrant Shares have been registered under the Securities Act of 1933, as amended (the “Act”) and are “restricted securities” under the Act inasmuch as they are being acquired in a transaction not involving a public offering. The Holder hereby agrees not to sell, transfer, assign, distribute, offer to sell, hypothecate or otherwise dispose of this Warrant or the Warrant Shares in the absence of: (i) an effective registration statement under the Act as to this Warrant or the Warrant Shares and the registration and/or qualification of this Warrant or the Warrant Shares under any applicable federal or state securities laws then in effect, or (ii) an exemption therefrom exists.

(ii) Subject to compliance with Section 7(c)(i) above and the provisions of Section 9(f) of this Warrant, this Warrant may be transferred by the Holder with respect to any or all of the shares purchasable hereunder. Upon surrender of this Warrant to the Company, together with the Assignment Form, attached hereto as Exhibit C duly executed, and funds sufficient to pay any transfer tax, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination or denominations specified in the Assignment Form and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned. Thereafter, this Warrant shall promptly be cancelled. This Warrant may be divided or combined with other

C-4

Warrants that carry the same rights upon presentation hereof at the office of the Company or at the office of its stock transfer agent, if any, together with a written notice specifying the names and denominations in which new Warrants are to be issued and signed by the Holder hereof. Notwithstanding the foregoing, the Company shall not be required to issue a Warrant covering less than 1,000 shares of Common Stock.

Xxxxxxxxx).

C-6

(a) Reclassification, etc. In case of any reorganization of the Company (or any other corporation, the securities of which are at the time receivable on the exercise of this Warrant) after the Warrant Issue Date or in case after such date the Company (or any such other corporation) shall consolidate with or merge into another corporation or convey all or substantially all of its assets to another corporation, then, and in each such case, the Holder of this Warrant upon the exercise thereof as provided herein at any time after the consummation of such reorganization, consolidation, merger or conveyance, shall be entitled to receive, in lieu of the securities and property receivable upon the exercise of this Warrant prior to such consummation, the securities or property to which such Holder would have been entitled upon such consummation if such Holder had exercised this Warrant immediately prior thereto; in each such case, the terms of this Warrant shall be applicable to the securities or property receivable upon the exercise of this Warrant after such consummation.

(b) Split, Subdivision or Combination of Shares. If the Company at any time while this Warrant, or any portion hereof, remains outstanding and unexpired shall split, subdivide or combine the securities as to which purchase rights under this Warrant exist, into a different number of securities of the same class, the Exercise Price for such securities shall be proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination.

(c) Adjustments for Dividends in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired, the holders of the securities as to which purchase rights under this Warrant exist at the time shall have received, or, on or after the record date fixed for the determination of eligible shareholders, shall have become entitled to receive, without payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend, then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of the security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of such other or additional stock or other securities or property (other than cash) of the Company that such holder would hold on the date of such exercise had it been the holder of record of the security receivable upon exercise of this Warrant on the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares and/or all other additional stock available by it as aforesaid during such period, giving effect to all adjustments called for during such period by the provisions of this Section 14.

Upon the occurrence of each adjustment or readjustment pursuant to this Section 14, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Holder of this Warrant a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request, at any time, of any such Holder, furnish or cause to be furnished to such Holder a like certificate setting forth: (i) such adjustments and readjustments; (ii) the Exercise Price at the time in effect; and (iii) the number of Warrant Shares and the amount, if any, of other property that at the time would be received upon the exercise of the Warrant.

C-9

(e) No Impairment. The Company will not, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 14 and in the taking of all such action as may be reasonably necessary or appropriate in order to protect the rights of the Holder of this Warrant against impairment.

15. Piggyback Registration Rights

15.1. If at any time during the period commencing on the Six Month Post-IPO Exercise Date and ending on the Expiration Date (the “Piggyback Registration Period”), the Company proposes to register any shares of its Common Stock under the Securities Act on any form for registration thereunder (the “Registration Statement”) for its own account or the account of shareholders (other than a registration solely relating to (i) shares of Common Stock underlying a stock option, restricted stock, stock purchase or compensation or incentive plan or of stock issued or issuable pursuant to any such plan, or a dividend investment plan; (ii) a registration of securities proposed to be issued in exchange for securities or assets of, or in connection with a merger or consolidation with, another corporation or other entity; or (iii) a registration of securities proposed to be issued in exchange for other securities of the Company), it will at such time give prompt written notice to the Holder of its intention to do so (the “Section 15.1 Notice”). Upon the written request of the Holder given to the Company within ten (10) days after the giving of any Section 15.1 Notice setting forth the number of shares of Warrant Shares intended to be disposed of by the Holder and the intended method of disposition thereof, the Company will include or cause to be included in the Registration Statement the shares of Warrant Shares which the Holder has requested to register, to the extent provided in this Section 15 (a “Piggyback Registration”). Notwithstanding the foregoing, the Company may, at any time, withdraw or cease proceeding with any registration pursuant to this Section 15.1 if it shall at the same time withdraw or cease proceeding with the registration of all of the Common Stock originally proposed to be registered. The Company shall be obligated to file and cause the effectiveness of only one (1) Piggyback Registration; provided however, that to the extent that shares for which registration is requested pursuant hereto are excluded under Section 15.5, such shares shall be eligible for Piggyback Registration, notwithstanding the one Piggyback Registration limit. The shares of Warrant Shares set forth in the Section 15.1 Notice are referred to for purposes of this Section 15 as the “Registrable Shares”.

15.2 Company Covenants. Whenever required under this Section 15 to include Registrable Shares in a Registration Statement, the Company shall, as expeditiously as reasonably possible:

(a) Use its commercially reasonable efforts to cause such Registration Statement to become effective and cause such Registration Statement to remain effective until the earlier of the Holder having completed the distribution of all its Registrable Shares described in the Registration Statement or six (6) months from the effective date of the Registration Statement (or such later date by reason of suspensions the effectiveness as provided hereunder). The Company will also use its commercially reasonable efforts to, during the period that such Registration

C-10

Statement is required to be maintained hereunder, file such post-effective amendments and supplements thereto as may be required by the Securities Act and the rules and regulations thereunder or otherwise to ensure that the Registration Statement does not contain any untrue statement of material fact or omit to state a fact required to be stated therein or necessary to make the statements contained therein, in light of the circumstances under which they are made, not misleading; provided, however, that if applicable rules under the Securities Act governing the obligation to file a post-effective amendment permits, in lieu of filing a post-effective amendment that (i) includes any prospectus required by Section 10(a)(3) of the Securities Act or (ii) reflects facts or events representing a material or fundamental change in the information set forth in the Registration Statement, the Company may incorporate by reference information required to be included in (i) and (ii) above to the extent such information is contained in periodic reports filed pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) in the Registration Statement.

(b) Prepare and file with the Unites States Securities and Exchange Commission (the “SEC”) such amendments and supplements to such Registration Statement, and the prospectus used in connection with such Registration Statement, as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement.

(c) Furnish to the Holder such numbers of copies of a prospectus, including a preliminary prospectus as amended or supplemented from time to time, in conformity with the requirements of the Securities Act, and such other documents as it may reasonably request in order to facilitate the disposition of Registrable Shares owned by the Holder; provided that, in no event, shall the Company be required to incur printing expenses in excess of $1,000 in complying with its obligations under this Section 15.2(c).

(d) Use its commercially reasonable efforts to register and qualify the securities covered by such Registration Statement under such other federal or state securities laws of such jurisdictions as shall be reasonably requested by the Holder; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act.

(e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering.

(f) Notify the Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, (a) when the Registration Statement or any post-effective amendment and supplement thereto has become effective; (b) of the issuance by the SEC of any stop order or the initiation of proceedings for that purpose (in which event the Company shall make use commercially reasonable efforts to obtain the withdrawal of any order suspending effectiveness of the Registration Statement. at the earliest possible time or prevent the entry thereof); (c) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Shares for sale in any jurisdiction or the initiation of any proceeding for such purpose; and (d) of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing.

C-11

(g) Cause all such Registrable Shares registered hereunder to be listed on each exchange or quotation service on which similar securities issued by the Company are then listed or quoted.

(h) Provide a transfer agent and registrar for all Registrable Shares registered pursuant hereunder and CUSIP number for all such Registrable Shares, in each case not later than the effective date of such registration.

15.3 Furnish Information. In connection with a registration in which the Holder is participating, such Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, the Holder shall provide, within ten (10) days of such request, such information related to such Holder as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act.

15.4 Expenses of Company Registration. All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Section 15.1, including, without limitation, all registration, filing and qualification fees, printers’ and accounting fees and fees, disbursements of counsel for the Company and disbursements of counsel for the Holder up to $10,000 (the “Registration Expenses”) shall be borne by the Company.

15.5 Underwriting Requirements. In connection with any offering involving an underwriting of shares of the Company’s capital stock, the Company shall not be required under Section 15.1 to include any of the Holder’s Registrable Shares in such underwriting unless the Holder accepts the terms of the underwriting as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine in their sole and reasonable discretion will not materially jeopardize the success of the offering by the Company, and the Holder enters into such lock-up agreements as may be reasonably required of other selling shareholders in such Registration Statement. If the total amount of securities, including Registrable Shares, requested by shareholders to be included in such offering exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole and reasonable discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Shares, which the underwriters determine in their sole and reasonable discretion will not materially jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling shareholders according to the total amount of securities entitled to be included therein owned by each selling shareholder or in such other proportions as shall mutually be agreed to by such

C-12

selling shareholders). For purposes of the preceding parenthetical concerning apportionment, for any selling shareholder who is a holder of Registrable Shares and is a partnership or corporation, the partners, retired partners and shareholders of such holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling shareholder”, and any pro-rata reduction with respect to such “selling shareholder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “selling shareholder”, as defined in this sentence.

15.6 Indemnification. In the event that any Registrable Shares are included in a Registration Statement under this Section 15.

(a) To the extent permitted by law, the Company will promptly indemnify and hold harmless the Holder, any underwriter (as defined in the Securities Act) for the Holder and each person, if any, who controls the Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, or the Exchange Act, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, or any rule or regulation promulgated under the Securities Act, or the Exchange Act, and the Company will pay to the Holder, underwriter or controlling person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 15.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action incurred by the Holder, underwriter or controlling person to the extent that such party’s loss, claim, damage, liability or action arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such party.

(b) To the extent permitted by law, the Holder will indemnify and hold harmless the Company, its directors, officers, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, any underwriter, any other holder selling securities in such Registration Statement and any controlling person of any such underwriter or other holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Securities Act, or the Exchange Act, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information

C-13

furnished by the Holder expressly for use in connection with such registration; and the Holder will pay, as incurred, any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this Section 15.6(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 15.6(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, further, that, in no event shall any indemnity under this Section 15.6(b) exceed 20% of the cash value of the gross proceeds from the offering received by the Holder.

(c) Promptly after receipt by an indemnified party under this Section 15.6 of notice of the commencement of any action (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party under this Section 15.6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly notified, to assume the defense thereof with counsel selected by the indemnifying party and approved by the indemnified party (whose approval shall not be unreasonably withheld); provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 15.6, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 15.6.

(d) If the indemnification provided for in this Section 15.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

C-14

(f) The obligations of the Company and the Holder under this Section 15.6 shall survive the completion of any offering of Registrable Shares in a Registration Statement under this Section 15, and otherwise.

15.7. Reports Under Securities Exchange Act of 1934. With a view to making available to the Holder the benefits of Rule 144 under the Securities Act (“Rule 144”) and any other rule or regulation of the SEC that may at any time permit the Holder to sell shares of the Company’s Common Stock to the public without registration, commencing immediately after the date on which a registration statement filed by the Company under the Securities Act becomes effective, the Company agrees to use its best efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144;

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(c) furnish to the Holder, so long as the Holder owns any Registrable Shares, forthwith upon request (i) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (ii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

15.8. Permitted Transferees. The rights to cause the Company to register Registrable Shares granted to the Holder by the Company under this Section 15 may be assigned in full by a Holder in connection with a transfer by the Holder of its Registrable Shares or Warrants if: (a) the Holder gives prior written notice to the Company; (b) such transferee agrees to comply with and be bound by the terms and provisions of this Agreement; (c) such transfer is otherwise in compliance with this Agreement and (d) such transfer is otherwise effected in accordance with applicable securities laws. Except as specifically permitted by this Section 15.8, the rights of a Holder with respect to Registrable Shares as set out herein shall not be transferable to any other person, and any attempted transfer shall cause all rights of the Holder therein to be forfeited.

15.9 Termination of Registration Rights. The Holder shall no longer be entitled to exercise any registration rights provided for in Section 15.1 after such time at which all Registrable Shares held by the Holder can be sold in any three-month period without registration in compliance with Rule 144 of the Act.

16. Information. So long as the Holder holds the Warrant and/or shares of Common Stock, the Company shall deliver to the Holder, promptly after mailing, copies of all notices, reports, financial statements, proxies or other written communication delivered or mailed to the holders of the Common Stock.

C-15

17. Descriptive Headings. The description headings of the several sections and paragraphs of this Warrant are inserted for convenience only and do not constitute a part of this Warrant.

18. Governing Law. This Warrant shall be construed and enforced under the laws of the State of Florida without regard to conflicts of law provisions

19. Waiver of Jury Trial. THE COMPANY AND THE HOLDER HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, OR RELATED TO, THE SUBJECT MATTER OF THIS AGREEMENT. THIS WAIVER IS KNOWINGLY, INTENTIONALLY AND VOLUNTARILY MADE BY THE HOLDER AND THE COMPANY.

FORM OF LEGAL OPINION

June 1, 2007

BlueCrest Capital Finance, L.P.
000 Xxxx Xxxxxxxxxx, Xxxxx 000
Xxxxxxx, XX 00000

Ladies and Gentlemen:

We have acted as Florida counsel to Bioheart, Inc., a Florida corporation (the “Borrower”), in connection with the transactions contemplated by the Loan and Security Agreement, dated May 31, 2007 (the “Loan Agreement”) by and between the Borrower and BlueCrest Capital Finance, L.P., a Delaware limited partnership (the “Lender”). This opinion is being furnished to you pursuant to Section 2.5(xiii) of the Loan Agreement. Capitalized terms used herein and not otherwise defined herein have the meanings assigned to them in the Loan Agreement.

This opinion is delivered at Borrower’s request as required by Lender in connection with the closing of the Loan. In our capacity as counsel to the Borrower, we have examined the following documents:

	a)		the Loan Agreement;

	b)		the Promissory Note, dated May 31, 2007, by the Borrower in favor of Lender in respect of Term Loan (the “Term Note”);

	c)		the Warrant Agreement, dated May 31, 2007, issued by the Borrower in favor of Lender (the “Warrant”);

	d)		the Deposit Account Control Agreement, dated May 31, 2007;

	e)		the form of UCC-1 financing statement to be filed with the Florida Secured Transactions Registry (the “Filing Office”) naming Lender as secured party and Borrower as debtor (the “Financing Statement”);

	f)		a certificate of the Chief Executive Officer, Chief Financial Officer and Executive Chairman of the Borrower, dated as of June 1, 2007 (the “Officers’ Certificate”), to which the following documents, among others, are attached: (i) the Articles of

D-1

			Incorporation (the “Articles”) of the Borrower, as amended, as certified on August 16, 2006, by the Secretary of State of the State of Florida; (ii) the Amended and Restated Bylaws of the Borrower (the “Bylaws” and with the Articles, the “Organizational Documents”); (iii) resolutions of the Board of Directors of the Borrower dated as of May 16, 2007; and (iv) minutes of a joint meeting of the Board of Directors and Audit Committee of the Borrower dated as of May 29, 2007; and

	g)		a certificate dated May 31, 2007 issued by the Secretary of State of the State of Florida to the effect that the Borrower is incorporated under the laws of the State of Florida and is in good standing.

The Loan Agreement, the Term Note, the Warrant and the Deposit Account Control Agreement are hereinafter collectively called the “Loan Documents.” The documents and instruments listed in (a) through (h) above are collectively referred to as the “Documents.”

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such other documents, agreements, certificates, corporate records, certificates of public officials and other instruments as we have deemed necessary or appropriate for the purposes of this opinion.

We are relying solely on the Loan Documents and the Organizational Documents in rendering the opinions set forth in this letter, subject to the limitations, assumptions and qualifications set forth below.

As to questions of fact material to the opinions expressed in this letter, we have relied upon, without independent investigation, and have assumed the correctness of the representations and warranties made in the Loan Documents and upon the certificates and documents referred to above, although we have no actual knowledge that they are true and correct.

In rendering the opinions expressed in this letter, we have assumed, and do not express an opinion with respect to (a) the power of each party (other than Borrower) to the agreements and documents submitted, (b) the due authorization of the execution, delivery and performance of each agreement and document submitted to us by each party thereto (other than Borrower), (c) the validity and binding nature of each agreement and document submitted to us on each party thereto (other than Borrower), (d) the genuineness of all signatures not witnessed by us and the authority of all persons signing each of the agreements and documents examined by us on which a signature appears (other than the authority of the officers of Borrower to execute and deliver the Loan Documents), (e) the accuracy, completeness and authenticity of all documents submitted to us as originals, (f) the conformity to original documents of all documents submitted

D-2

to us as certified or photostatic copies and that each such document has been duly executed and delivered by each party thereto pursuant to due authorization (other than the due execution and delivery by Borrower), (g) the veracity of all documents, affidavits and certificates submitted to us, (h) the legal capacity of natural persons and (i) the valid existence and good standing of all parties to the Loan Documents (other than the valid existence and good standing of Borrower). In further rendering the opinions expressed in this letter, we do not express an opinion with respect to the following and we have assumed that (i) the signed Loan Documents to which we opine will be in substantially the same form as the drafts submitted to us for our review, (ii) there have been no further modifications to the documents described above, (iii) the execution and delivery of the Loan Documents are free from any fraud, unconscionability, misrepresentation, mistake of fact, duress or criminal activity, (iv) there are no other documents or agreements among the Lender and the Borrower which would expand, modify or otherwise alter the respective obligations and rights of the parties to the Loan Documents, (v) in the event the Lender ever seeks to enforce its rights under the Loan Documents, the Lender will not itself be in breach thereof nor will any applicable statute of limitations have expired, (vi) the Lender shall act in a commercially reasonable manner and in compliance with all laws applicable to the Lender, and (vii) valid and adequate consideration has been received in connection with the transactions contemplated by the Loan Documents. We have also assumed, without investigation, that all conditions precedent to closing the transactions contemplated by the Loan Documents have been satisfied in all material respects.

We have further assumed (a) that the Lender has all requisite power and authority to carry on its business as now being conducted; and (b) that the Lender has duly authorized by all necessary corporate or other applicable action, the execution, delivery and performance of the Loan Documents to which it is a party.

Our opinions set forth in this letter as to the legality, validity, binding effect and enforceability of the Loan Documents are specifically qualified to the extent that the legality, validity, binding effect or enforceability of any obligations of the Borrower under the Loan Documents, or the availability or enforceability of any of the remedies provided in the Loan Documents, may be subject to or limited by (a) bankruptcy, insolvency, reorganization, fraudulent conveyance and fraudulent transfer, moratorium and other statutory or decisional laws, now or hereafter in effect, affecting the rights of creditors generally, (b) State of Florida and federal constitutional limitations, including, without limitation, notice and due process requirements, the right to a trial by jury and the right to present permissible counterclaims, cross-claims or other actions, provided that none of such matters affect the overall validity of the Loan Documents or interfere with the practical realization of the principal benefits intended to be provided by the Loan Documents, (c) the exercise of judicial or administrative discretion in accordance with general equitable principles, including, without limitation, concepts of specific

D-3

performance, injunctive relief and other equitable remedies (regardless of whether enforcement is sought in a proceeding at law or in equity), (d) the Lender’s implied duty of good faith, (e) the rights of the United States of America pursuant to the Federal Tax Lien Act of 1966, as amended, and (f) the availability or enforceability of particular remedies, of exculpatory provisions, of indemnities and rights of contribution and of waivers contained in the Loan Documents, which particular remedies, exculpatory provisions, indemnities and rights of contribution and waivers may be limited by or subject to equitable principles, applicable laws, rules, regulations, court decisions and constitutional requirements and the discretion of the court before which any proceeding for relief may be brought.

No opinion is expressed herein with respect to the existence of or any title to property (real or personal, tangible or intangible), the perfection or priority of any security interest or other lien, environmental laws, antitrust laws, state securities law exemptions or the law of fiduciary duty. No opinion is expressed as to choice of law provisions in any of the Loan Documents or to the adequacy of the description of any of the collateral contained in the Loan Documents. We express no opinion as to the validity or enforceability of a security interest arising out of any transaction not subject to Article 9 of the Uniform Commercial Code as in effect on the date hereof in the State of Florida (the “Florida UCC”), including those described in §§ 679.1091(3) and (4) of the Florida UCC.

With respect to the opinions expressed in paragraph 3 below, we note that the perfection of any security interest that has been perfected by the filing of the Financing Statement in Florida will expire upon the earliest to occur of (i) the expiration of four months after the debtor so changes its name that the financing statement becomes seriously misleading under § 9-506 and § 9-507 of the Uniform Commercial Code as in effect in Florida (the “Florida UCC”) as to any collateral acquired more than four months after such change, unless within such four-month period an amendment which renders the financing statement not seriously misleading is filed; (ii) with respect to collateral, a security interest in which has not attached on or prior to the date of change of location, the expiration of the four-month period after a change of the debtor’s location, unless the secured party becomes perfected within such four-month period under the law of the debtor’s new jurisdiction, or (iv) the expiration of one year after the transfer of collateral by the debtor to a person that becomes a debtor and is located in another jurisdiction within the meaning of § 9-307 of the Florida UCC, unless the secured party becomes perfected as to the transferred collateral within the one-year period under the laws of the location of the transferee debtor. To the extent that Florida law continues to govern the effect of the Financing Statement, continuation statements complying with the Florida UCC must be filed in the Filing Office in order to maintain the effectiveness of the Financing Statement, as provided therein.

D-4

The opinions set forth in paragraph 3 below also are subject to the following additional limitations and exclusions:

(i) We express no opinion as to the validity, perfection or enforceability of a security interest arising out of any transaction not subject to Article 9 of the Florida UCC, including those described in §§ 9-109(c) and (d) of the Florida UCC, and therefore our opinions set forth in paragraph 3 below do not address (A) laws other than Article 9 of the Florida UCC, (B) collateral of a type not subject to Article 9 of the Florida UCC, and (C) what law governs perfection of the security interests granted in the collateral covered by this opinion letter.

(ii) We express no opinion with respect to any “commercial tort claim,” “letter-of-credit-right,” collateral arising from a “consumer transaction,” “health-care-insurance-receivable,” “agricultural lien,” “farm products” or “as-extracted collateral,” “investment property” or “manufactured home collateral” (as those terms are defined in Article 9 of the Florida UCC), collateral subject to a certificate of title, goods consigned by or to the Borrower, documents or goods covered by documents, electronic chattel paper (other than perfection by filing as set forth above), or standing timber.

(iii) Under §§ 9-315 of the Florida UCC, the continuation of perfection of a security interest in proceeds is limited to the extent set forth in such section.

(iv) Under § 9-316 of the Florida UCC, the continuation of perfection of a security interest following a change in the jurisdiction, the laws of which govern perfection, the effect of perfection and non-perfection and priority, is limited to the extent set forth in such section.

(v) In the case of property that becomes collateral after the date hereof, Section 552 of the Federal Bankruptcy Code limits the extent to which property acquired by a debtor after the commencement of a case under the Federal Bankruptcy Code may be subject to a security interest arising from a security agreement entered into by the debtor before the commencement of such a case.

(vi) The Financing Statement might become ineffective due to events that cause them to be “seriously misleading” under §§ 9-506 through § 9-508 of the Florida UCC.

(vii) We note that the secured party’s rights against account debtors will be subject to the terms of the assigned account, chattel paper or general intangible, to dealings between such account debtor and the Borrower, and to the other limitations provided in §§ 9-403, 9-404, 9-405 and 9-406 of the Florida UCC, and will be subject to defenses as provided in § 9-404 of the Florida UCC.

D-5

(viii) We express no opinion as to the effectiveness of the secured party’s security interest as to any rights (including rights of payment) under any account or other obligation on which the United States government or any other federal, state, local, foreign or other government or any agency, department or subdivision thereof is an obligor.

(ix) We note that pursuant to §§ 9-203(f) and (g) and §§ 9-308(d) and (e) of the Florida UCC, (i) perfection of a security interest in collateral also perfects a security interest in any supporting obligation (as defined in Article 9 of the Florida UCC) for such collateral and (ii) perfection of a security interest in a right to payment or performance also perfects a security interest in any security interest, mortgage or other lien on personal or real property securing such right to payment or performance (a “Supporting Lien”). Except to the extent that any such supporting obligation or Supporting Lien constitutes Collateral, we express no opinion as to the creation or perfection, respectively, of a security interest therein.

(x) We express no opinion with respect to the enforceability of a security interest in any security entitlement credited to a securities account or any commodity contract credited to a commodities account.

(xi) We express no opinion as to whether any deposit account of the Borrower constitutes a “deposit account” within the meaning of Article 9 of the Florida UCC.

For the purposes of the opinions in paragraph 3 below, we also have assumed that:

(i) The Borrower is not a “transmitting utility” as defined in § 9-102 of the Florida UCC;

(ii) The requirements for enforceability of the security interest under § 9-203(b) of the Florida UCC have been satisfied; and

(iii) None of the Collateral has been leased by the Borrower to any third party in what would be characterized as a “lease intended as security” within the meaning of § 1-201(37) of the Florida UCC.

For the purposes of the opinions in paragraph 5 below, we have also assumed that:

(i) The Lender will file the Financing Statement with the Filing Office; and

D-6

(ii) The Lender will pay the documentary stamp taxes on behalf of the Borrower, since the amount of such taxes is to be deducted by the Lender from the proceeds of the Term Loan.

We express no opinion regarding (i) the submission of jurisdiction to the extent it relates to the subject matter jurisdiction of any court, (ii) the enforceability of any waiver of a trial by jury or waiver of objection to venue or claim of an inconvenient forum with respect to proceedings, (iii) the waiver of any right to have service of process made in the manner presented by applicable law, (iv) the appointment of any party as attorney in fact insofar as exercise of such power of attorney may be limited by public policy or limitations referred to elsewhere in this opinion, (v) the enforceability of indemnification or contribution provided for in the Loan Documents for claims, losses or liabilities in an unreasonable amount, for claims, losses or liabilities attributable to the indemnified party’s negligence, or to the extent enforceability of such indemnifications may be barred or limited by federal or state securities laws, (vi) the ability of any party to receive the remedies of specific performance, injunctive relief, liquidated damages, penalties or any similar remedy in any proceeding (including, without limitation prepayment penalties and yield maintenance provisions), (vii) any right to the appointment of a receiver or the enforceability of any agreement by the owner of the applicable property to consent to such appointment, (viii) any right to obtain possession of any property or the exercise of self-help remedies or other remedies without judicial process, (ix) any waiver or limitation concerning mitigation of damages, (x) the availability of the right of rescission, (xi) whether a Florida court would enforce provisions of the Loan Documents purporting to override applicable rules of court procedure, evidence or due process of law, (xii) arbitration or mediation provisions, (xiii) provisions to the effect that the Lender’s or any other party’s failure to exercise any right, remedy or option under the Loan Documents shall not operate as a waiver, (xiv) provisions for the reimbursement by the non-prevailing party of the prevailing party’s legal fees and expenses, (xv) the waiver of defenses, rights or remedies or the delay or omission of enforcement thereof, (xvi) waiver of the benefit of any constitutional, statutory or common law right to the extent that such a waiver is deemed to violate public policy, (xvii) the enforceability of any provision modifying the interest rate ipso facto under the Note or other interest “savings” clause to the extent that the interest rate is determined to be usurious, (xviii) waiver or renouncement of the benefits of any moratorium, statute of limitations, reinstatement, marshalling, forbearance, appraisement, exemption or homestead laws, (xix) any rights of set-off, (xx) the payment of interest on interest, or (xxi) the application of foreclosure sales proceeds in any manner contrary to Florida law; (xxii) any release, discharge or covenant not to xxx with respect to unknown act or omissions to act or acts which subsequently accrue or mature; (xxiii) the waiver of any rights, rules or duties imposed upon a secured party under the Florida Uniform Commercial Code which are stated to be non-waivable thereunder; or (xxiv) the imposition of joint and several liability.

D-7

We have assumed that there are no oral modifications or written agreements or understandings which limit, modify or otherwise alter the terms, provisions, and conditions of, or relate to, the Loan Documents and the other transactions contemplated by the Loan Documents.

The phrases “to our knowledge,” “to the best of our knowledge,” “known to us” or the like mean to the current actual knowledge of the attorneys of this firm who have actively and directly participated in the negotiation and closing of the transactions contemplated by the Loan Documents and who have devoted substantive attention to the transactions contemplated by the Loan Documents and does not include matters of which such attorneys could otherwise be deemed to have constructive knowledge.

We have not undertaken or reviewed any search of court or governmental dockets or records in any jurisdiction, any search with respect to the rights or assets of any party to the Loan Documents or any Uniform Commercial Code, suit, judgment, lien or other type of search or investigation, except as stated above.

We express no opinion as to the effect on the opinions expressed herein of the compliance or non-compliance of the Borrower or any other party to the Loan Documents with any state, federal or other laws or regulations applicable to it.

As to matters of fact relevant to this opinion, we have relied without independent investigation on, and assumed the accuracy and completeness of, the representations and warranties of all parties in the Loan Documents and the Officers’ Certificate. We have not made an investigation as to, and have not independently verified the facts underlying such representations and warranties or the matters covered by the Officers’ Certificate.

Except for the opinions expressly set forth in the numbered paragraphs below, we express no opinions and no opinions should be implied or inferred. Based upon and subject to the foregoing, we are of the opinion that:

	1.		The Borrower is a corporation duly organized, validly existing and in good standing under the laws of Florida with corporate powers adequate for the execution, delivery, and performance of the Loan Documents. The Borrower has all requisite corporate power and authority to own and operate its properties and assets and to carry on its business as it is currently being conducted.

	2.		Each of the Loan Documents has been duly authorized, executed and delivered by the Borrower, constitutes the legal, valid, and binding obligation of the Borrower, and is enforceable against the Borrower in accordance with its terms.

D-8

	3.		The Financing Statement is in form suitable for filing. The Filing Office is the only office in which the Financing Statement is required to be filed to publish notice of the security interest in that personal property and other collateral described in the Financing Statement in which a security interest may be perfected solely by filing under the Florida UCC (the “FL UCC Collateral”). The filing of the Financing Statement in the Filing Office will result in the perfection of the security interests in such portions of the Florida UCC Collateral which are described in said Financing Statement and in which a security interest may be perfected solely by filing under Article 9 of the Florida UCC. No opinion is expressed herein with respect to the relative priority of these security interests.

	4.		The execution and delivery by the Borrower of the Loan Documents do not, and the performance by the Borrower of the terms of the Loan Documents will not, (i) result in any violation or breach by the Borrower of any statute, rule or regulation, or, to our knowledge, any judgment, ruling, decree, or order of any court or other governmental agency or body applicable to the business or properties of the Borrower, (ii) violate the Articles of Incorporation, as amended, or the By-Laws, as amended, of the Borrower, or (iii) result in any default under any agreement or instrument listed on Exhibit A hereto.

	5.		Under material provisions of law, no approval or authorization by, or notice to or filing with, any federal or state governmental authority or the Secretary of State of Florida is required to be obtained or performed by the Borrower in connection with the execution, delivery, or performance of the Loan Documents.

	6.		Except as previously disclosed by the Borrower to the Lender, and to the knowledge of the attorneys who have actively and directly participated in the representation of the Borrower, there is no litigation or governmental proceeding or investigation pending, or threatened, against the Borrower which questions the validity or enforceability of the Loan Documents or, if determined adversely to the Borrower, could be reasonably expected to have a material adverse impact on the business or assets of the Borrower.

However, while certain members of this firm are admitted to practice in other jurisdictions, in this opinion letter we do not express any opinion covering any law other than the laws of the State of Florida. We are members of the bar of the State of Florida and are not purporting to be experts on, or generally familiar with, or qualified to express legal conclusions based upon, laws of any state or jurisdiction other than the United States of America and the State of Florida.

D-9

The opinions expressed above are subject to the exception that the enforceability of any of the documents may be limited by public policy and concepts of materiality, unconscionability, reasonableness, good faith and fair dealing.

This opinion is solely for your benefit and it is not to be quoted in whole or in part or otherwise referred to, nor is it to be filed with any governmental agency or any other person, and no person or entity other than you (or any successors or assigns of the Loan Agreement and the Term Note) shall be entitled to rely upon this opinion without our express written consent. This opinion is given as of the date hereof, and we assume no obligation to advise you after the date hereof of facts or circumstances that come to our attention or changes in law that occur which could affect the opinion contained herein. We undertake no duty to inform you of events occurring subsequent to the date hereof.
