3. COLLATERAL.

(a)

Until the declaration of any default, Debtor shall remain in possession of the Collateral; except that Secured Party shall have the right to possess (i) any chattel paper or instrument that constitutes a part of the Collateral, and (ii) any other Collateral in which Secured Party’s security interest may be perfected only by possession. Secured Party may inspect any of the Collateral during normal business hours after giving Debtor reasonable prior written notice except (i) in the event of exigent circumstances or (ii) after the occurrence of an event of default or

an event (which with the passage of time might ripen into an event of default) has occurred in which verbal notice shall suffice. In connection with any such inspection, Secured Party shall coordinate with Debtor in order to minimize the disruption to Debtor’s use of the Collateral. Secured Party hereby acknowledges that Debtor’s use of the Collateral includes the storage and handling of hazardous materials and biologic agents and that Secured Party’s entry into the premises where the Collateral is located, without a Debtor representative, will be at Secured Party’s peril. Notwithstanding anything to the contrary set forth in this Agreement, Secured Party will not be permitted access to areas previously designated in writing by Debtor as security areas, unless Secured Party or its representatives are accompanied by (i) an agent of Debtor designated by Debtor for such purpose or (ii) other qualified expert familiar with the necessary precautions to be taken in the presence of any extant biohazards. Any inspection by Secured Party or its agents and invitees hereunder shall be subject to compliance with such reasonable confidentiality and security procedures as are reasonably imposed on Debtor’s business operations and Debtor’s standard operating procedures except to the extent that: (i) an event of default or an event (which with the passage of time might ripen into an event of default) has occurred; or (ii) Secured Party has determined in its sole and reasonable discretion that (a) the Collateral is in jeopardy or (b) its Security Interest in the Collateral is in jeopardy. Any such entry into the premises by Secured Party where the Collateral is located, without a Debtor representative, will be at Secured Party’s peril.

	(b)		Debtor shall use commercially reasonable efforts to (i) use the Collateral only in its trade or business, (ii) maintain all of the Collateral in good operating order and repair, normal wear and tear excepted, (iii) use and maintain the Collateral only in compliance with manufacturers recommendations and all applicable laws, and (iv) keep all of the Collateral free and clear of all liens, claims and encumbrances (except for Permitted Liens).
	(c)		Secured Party does not authorize and Debtor agrees it shall not (i) part with possession of any of the Collateral (except to Secured Party or for maintenance and repair), (ii) remove any of the Collateral from the continental United States, or (iii) sell, rent, lease, mortgage, license, grant a security interest in or otherwise transfer or encumber (except for Permitted Liens) any of the Collateral, provided that Debtor may, with the consent of Secured Party, such consent not to be unreasonably withheld, sell, rent, encumber, license, lease or otherwise transfer or dispose of any Collateral that is obsolete and has been replaced in the ordinary course.
	(d)		Debtor shall pay promptly when due all taxes, license fees, assessments and public and private charges levied or assessed on any of the Collateral, on its use, or on this Agreement or any of the other Debt Documents, except for those contested in good faith. At its option, Secured Party may discharge taxes, liens, security interests or other encumbrances at any time levied or placed on the Collateral and may pay for the maintenance, insurance and preservation of the

Collateral and effect compliance with the terms of this Agreement or any of the other Debt Documents. Debtor agrees to reimburse Secured Party, on demand, all reasonable costs and expenses incurred by Secured Party in connection with such payment or performance and agrees that such reimbursement obligation shall constitute Indebtedness.

	(e)		Debtor shall, at all times, keep accurate and complete records of the Collateral, and Secured ▇▇▇▇▇ shall have the right to inspect and make copies of all of Debtor’s books and records relating to the Collateral during normal business hours, after giving Debtor reasonable prior written notice except (i) in the event of exigent circumstances or (ii) after the occurrence of an event of default or an event (which with the passage of time might ripen into an event of default) has occurred in which verbal notice shall suffice.
	(f)		Debtor agrees and acknowledges that any third person who may at any time possess all or any portion of the Collateral shall be deemed to hold, and shall hold, the Collateral as the agent of, and as pledge holder for, Secured Party. Secured Party may at any time give written notice to any third person described in the preceding sentence that such third person is holding the Collateral as the agent of, and as pledge holder for, the Secured Party.

4. INSURANCE.

	(a)		Debtor shall at all times bear the entire risk of any loss, theft, damage to, or destruction of, any of the Collateral from any cause whatsoever.
	(b)		Debtor agrees to keep the Collateral insured against loss or damage by fire and extended coverage perils, theft, burglary, and for any or all Collateral, which are vehicles, for risk of loss by collision, and if requested by Secured Party, against such other risks as Secured Party may reasonably require. The insurance coverage shall be in an amount no less than the full replacement- value of the Collateral, and deductible amounts, insurers and policies shall be reasonably acceptable to Secured Party. Debtor shall deliver to Secured Party policies or certificates of insurance evidencing such coverage. Each policy shall name Secured Party as a loss payee, shall provide for coverage to Secured Party regardless of the breach by Debtor of any warranty or representation made therein, shall not be subject to co-insurance, and shall provide that coverage may not be canceled or altered by the insurer except upon thirty (30) days prior written notice to Secured Party. Debtor appoints Secured Party as its attorney-in-fact to make proof of loss, claim for insurance and adjustments with insurers, and to receive payment of and execute or endorse all documents, checks or drafts in connection with insurance payments. Secured Party shall not act as Debtor’s attorney-in-fact unless Debtor is in default. Proceeds of insurance during a default hereunder shall be applied, at the option of Secured Party, to repair or replace the Collateral or to reduce any of the Indebtedness. Any excess proceeds shall be paid to, and retained by, Debtor.

	(b)		Debtor will deliver to Secured Party within ninety (90) days of the close of each fiscal year of Debtor, Debtor’s complete financial statements including a balance sheet, income statement, statement of shareholders’ equity and statement of cash flows, each prepared in accordance with generally accepted accounting principles consistently applied, certified by a recognized firm of certified public accountants reasonably satisfactory to Secured Party.

Debtor will deliver to Secured Party copies of all Forms 10-K and 10-Q, if any, within 30 days after the dates on which they are filed with the Securities and Exchange Commission. Debtor will deliver to Secured Party copies of Debtor’s monthly financial statements including a balance sheet and income statement, each prepared by Debtor in accordance with generally accepted accounting principles consistently applied by Debtor within forty-five (45) days after the close of each month. Debtor will deliver to Secured Party promptly upon request of Secured Party, in form reasonably satisfactory to Secured Party, such other and additional information relating hereto as Secured Party may reasonably request from time to time.

6. FURTHER ASSURANCES.

(a)

Debtor shall, upon request of Secured Party, furnish to Secured Party such further information, execute and deliver to Secured Party such documents and instruments (including, without limitation, Uniform Commercial Code financing statements) and shall do such other acts and things as Secured Party may at any time reasonably request relating to the perfection or protection of the security interest created by this Agreement or for the purpose of carrying out the intent of this Agreement. Without limiting the foregoing, Debtor shall cooperate and do all acts deemed reasonably necessary by Secured Party to continue in Secured Party a perfected first security interest in the Collateral, and shall use in commercially reasonable efforts to obtain and furnish to Secured Party any subordinations, releases, landlord waivers, lessor waivers, mortgagee waivers, or control agreements, and similar documents as may be from time to time reasonably requested by, and in form and substance reasonably satisfactory to, Secured Party.

	(b)		Debtor shall perform any and all acts requested by the Secured Party to establish, maintain and continue the Secured Party’s security interest and liens in the Collateral, including but not limited to, executing or authenticating financing statements and such other instruments and documents when and as reasonably requested by the Secured Party. Debtor hereby authorizes Secured Party through any of Secured Party’s employees, agents or attorneys to file any and all financing statements, including, without limitation, any original filings, continuations, transfers or amendments thereof required to perfect Secured Party’s security interest and liens in the Collateral under the UCC without authentication or execution by Debtor. Debtor hereby irrevocably authorizes the Secured Party at any time and from time to time to file in any filing office in any Uniform Commercial Code jurisdiction any initial financing statement(s) and amendments thereto that (a) indicate the Collateral (i) as assets of the Debtor or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the Uniform Commercial Code of the State or such jurisdiction, or (ii) as being of an equal or lesser scope or with greater detail, and (b) provide any other information required by part 5 of Article 9 of the Uniform Commercial Code of the State or such other jurisdiction for the sufficiency or filing office acceptance of any financing statement or amendment, including (i) whether the Debtor is an organization, the type of organization and any organization identification number issued to the Debtor, and (ii) in the case of a financing statement filed as a fixture filing, a sufficient description of real property to which the Collateral relates. The Debtor agrees to furnish any such information to the Secured Party promptly upon the Secured Party’s request.
	(c)		Debtor shall indemnify and defend the Secured Party, its successors and assigns, and their respective directors, officers and employees (collectively, the “Indemnitees”), from and against all claims, actions and suits (including, without limitation, related reasonable attorneys’ fees) of any kind whatsoever arising, directly or indirectly, in connection with any of the Collateral except such as may be caused by gross negligence or willful misfeasance of the applicable Indemnitee.

7. DEFAULT AND REMEDIES.

(a)

Debtor shall be in default under this Agreement and each of the other Debt Documents if,

	(i)		Debtor breaches its obligation to pay when due any amount under any of the Debt Documents and fails to cure such breach within five (5) days;
	(ii)		Debtor, without the prior written consent of Secured Party, attempts to or does sell, rent, lease, license, mortgage, grant a security interest in, or otherwise transfer or encumber (except for Permitted Liens) any of the Collateral, it being understood that Debtor may, with the consent of Secured Party, such consent not to be unreasonably withheld, sell, rent,

	(iii)		Debtor breaches any of its insurance obligations under Section 4;

	(vi)		Any material portion of the Collateral is subjected to attachment, execution, levy, seizure or confiscation in any legal proceeding or otherwise, or if any legal or administrative proceeding is commenced against Debtor or any of the Collateral, which in the good faith judgment of Secured Party subjects any material portion of the Collateral to a material risk of attachment, execution, levy, seizure or confiscation and no bond is posted or protective order obtained to negate such risk;
	(vii)		Debtor breaches or is in material default under any other agreement between Debtor and Secured Party;
	(viii)		Debtor dissolves, terminates its existence, becomes insolvent or ceases to do business as a going concern;
	(ix)		A receiver is appointed for all or of any part of the property of Debtor and is not discharged within forty-five (45) days, or Debtor makes any assignment for the benefit of creditors;

	(x)		Debtor files a petition under any bankruptcy, insolvency or similar law, or any such petition is filed against Debtor and is not dismissed within forty-five (45) days;
	(xi)		Debtor’s improper filing of an amendment or termination statement relating to a filed financing statement describing the Collateral;
	(xii)		Debtor, without the prior written consent of Secured Party, shall (i) merge with or consolidate into any other entity if the resulting entity’s overall financial condition after the merger or consolidation is materially worse than the overall financial condition of Debtor before the merger or consolidation in the Secured Party’s reasonable opinion or (ii) sell all or substantially all of its assets. Upon Debtor’s merger or consolidation, sale of all or substantially all of its assets, or liquidation or other termination of existence, Debtor may prepay the Indebtedness upon payment of (i) all accrued and unpaid interest and the outstanding principal balances of the Notes as of the date of such payment and (ii) an amount equal to three

(3%) of the outstanding principal balance of the Notes on the date of prepayment. If Secured Party consents to the merger or consolidation, the acquiring, surviving or successor entity must agree in writing to assume the Debtor’s obligations under the Debt Documents;

	(xiii)		If Debtor is a privately held corporation, more than 25% of Debtor’s voting capital stock, or effective control of Debtor’s voting capital stock, issued and outstanding from time to time, is not retained by the holders of such stock on the date the Agreement is executed, except as may result from the initial public offering of the Debtor’s securities;
	(xiv)		If Debtor is a publicly held corporation, there shall be a change in the ownership of Debtor’s stock such that Debtor is no longer subject to the reporting requirements of the Securities Exchange Act of 1934 or no longer has a class of equity securities registered under Section 12 of the Securities Act of 1933;
	(xv)		Debtor’ defaults under any other financing arrangement between Debtor and a third party (other than a default where the aggregate payment by Debtor to a third party amounts to less than $100,000 annually); and
	(xvi)		Secured Party shall have determined in its good faith, sole and reasonable judgment that there has been a material adverse change in the Debtor’s business plan, from the date hereof, and as amended and accepted in its entirety by Secured Party from time to time, which would materially impair the ability of Debtor to perform its obligations hereunder or of Secured Party to enforce the Indebtedness or realize upon the Collateral.

	(b)		If Debtor is in default, the Secured Party, at its option, may declare any or all of the Indebtedness to be immediately due and payable, without demand or notice to Debtor. The accelerated obligations and liabilities shall bear interest (both before and after any judgment) until paid in full at the lower of thirteen percent (13%) per annum or the maximum rate not prohibited by applicable law.
	(c)		For so long as a default has occurred and is continuing, Secured Party shall have all of the rights and remedies of a Secured Party under the Uniform Commercial Code “UCC”, and under any other applicable law. Without limiting the foregoing, Secured Party shall have the right to (i) notify any account debtor of Debtor or any obligor on any instrument which constitutes part of the Collateral to make payment to the Secured Party, (ii) with or without legal process, enter any premises where the Collateral may be and take possession of and remove the Collateral from the premises or store it on the premises, (iii) sell the Collateral at public or private sale, in whole or in part, and have the right to bid and purchase at said sale (subject to the commercially reasonableness requirements of Section 9-610 of the UCC), or (iv) lease or otherwise dispose (subject to the commercially reasonableness requirements of Section 9-610 of the UCC) of all or part of the Collateral, applying proceeds from such disposition to the obligations then in

default. If requested by Secured Party, Debtor shall promptly assemble the Collateral and make it available to Secured Party at a place to be designated by Secured Party, which is reasonably convenient to both parties. Secured Party may also render any or all of the Collateral unusable at the Debtor’s premises and may dispose of such Collateral on such premises without liability for rent or costs. Any notice that Secured Party is required to give to Debtor under the Uniform Commercial Code of the time and place of any public sale or the time after which any private sale or other intended disposition of the Collateral is to be made shall be deemed to constitute reasonable notice if such notice is given to the last known address of Debtor at least ten (10) days prior to such action. Upon the occurrence and during the continuation of a default, Debtor hereby appoints Secured Party as Debtor’s attorney-in-fact, with full authority in Debtor’s place and stead and in Debtor’s name or otherwise, from time to time in Secured Party’s sole and arbitrary discretion, to take any action and to execute any instrument which Secured Party may deem reasonably necessary or advisable to accomplish the purpose of this Agreement.

	(d)		Proceeds from any sale or lease or other disposition shall be applied: first, to all reasonable costs of repossession, storage, and disposition including without limitation reasonable attorneys’, appraisers’, and auctioneers’ fees; second, to discharge the obligations then in default; third, to discharge any other Indebtedness of Debtor to Secured Party, whether as obligor, endorser, guarantor, surety or indemnitor; fourth, to expenses incurred in paying or settling liens and claims against the Collateral; and lastly, to Debtor, if there exists any surplus. Debtor shall remain fully liable for any deficiency.
	(e)		Debtor agrees to pay all reasonable attorneys’ fees and other costs incurred by Secured Party in connection with the enforcement, assertion, defense or preservation of Secured Party’s rights and remedies under this Agreement, or if prohibited by law, such lesser sum as may be permitted. Debtor further agrees that such fees and costs shall constitute Indebtedness.
	(f)		Secured Party’s rights and remedies under this Agreement or otherwise arising are cumulative and may be exercised singularly or concurrently. Neither the failure nor any delay on the part of the Secured Party to exercise any right, power or privilege under this Agreement shall operate as a waiver, nor shall any single, or partial exercise of any right, power or privilege preclude any other or further exercise of that or any other right, power or privilege. SECURED PARTY SHALL NOT BE DEEMED TO HAVE WAIVED ANY OF ITS RIGHTS UNDER THIS AGREEMENT OR UNDER ANY OTHER AGREEMENT, INSTRUMENT OR PAPER SIGNED BY DEBTOR UNLESS SUCH WAIVER IS EXPRESSED IN WRITING AND SIGNED BY SECURED PARTY. A waiver on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion.

(g)

DEBTOR AND SECURED PARTY UNCONDITIONALLY WAIVE THEIR RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION

BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN DEBTOR AND SECURED PARTY.

	(a)		This Agreement, any Note and/or any of the other Debt Documents may be assigned, in whole or in part, by Secured Party with written notice to Debtor, and Debtor agrees not to assert against any such assignee, or assignee’s assigns, any defense, set-off, recoupment claim or counterclaim which Debtor has or may at any time have against Secured Party for any reason whatsoever. Debtor agrees that if Debtor receives written notice of an assignment from Secured Party, Debtor will pay all amounts payable under any assigned Debt Documents to such assignee or as instructed by Secured Party.

This Agreement shall automatically be reinstated if Secured Party is ever required to return or restore the payment of all or any portion of the Indebtedness (all as though such payment had never been made).
