(i) Subject to the terms and conditions set forth herein and in the Ancillary Agreements, Calliope may make revolving loans (the “Revolving Loans”) to the Parent from time to time during the Term which, in the aggregate at any time outstanding, will not exceed the lesser of (x) (I) the Capital Availability Amount minus (II) such reserves as Calliope may reasonably in its good faith judgment deem proper and necessary from time to time (the “Reserves”) and (y) an amount equal to (I) the Accounts Availability plus (II) the Inventory Availability, minus (III) the Reserves. The amount derived at any time from Section 2(a)(i)(y)(I) plus Section 2(a)(i)(y)(II) minus 2(a)(i)(y)(III) shall be referred to as the “Formula Amount.” The Parent shall execute and deliver to Calliope on the Closing Date the Secured Revolving Note and the Secured Convertible Term Note. The Parent hereby acknowledges and agrees that Calliope’s obligation to purchase the Secured Revolving Note and the Secured Convertible Term Note from the Parent on the Closing Date shall be contingent upon the satisfaction (or waiver by Calliope in its sole discretion) of the items and matters set forth in the closing checklist provided by Calliope to the Parent on or prior to the Closing Date. The Parent hereby further acknowledges and agrees that, immediately prior to each borrowing hereunder and immediately after giving effect thereto, the Parent shall be deemed to have certified to Calliope that at the time of each such proposed borrowing and also after giving effect thereto (i) there shall exist no Event of Default, (ii) all representations, warranties and covenants made by the Parent in connection with this Agreement and the Ancillary Agreements are true, correct and complete and (iii) all of Parent’s covenant requirements under this Agreement and the Ancillary Agreements have been met. The Parent hereby agrees to provide a certificate confirming the foregoing concurrently with each request for a borrowing hereunder.

(ii) Notwithstanding the limitations set forth above, if requested by Parent, Calliope retains the right to lend to Parent from time to time such amounts in excess of such limitations as Calliope may determine in its sole discretion. In connection with each such request by Parent, the Parent shall be deemed to have certified, as of the time of such proposed borrowing and immediately after giving effect thereto, to the satisfaction of all Overadvance Conditions. For purposes hereof, “Overadvance Conditions” means (i) no Event of Default shall exist and be continuing as of such date; (ii) all representations, warranties and covenants made by the Parent in connection with the Security Agreement and the Ancillary Agreements shall be true, correct and complete as of such date; and (iii) the Parent shall have taken all action necessary to grant Calliope “control” over all of the Parent’s ’ Deposit Accounts (the “Control Accounts”), with any agreements establishing “control” to be in form and substance satisfactory to Calliope. “Control” over such Control Accounts shall be released upon the indefeasible repayment in full and termination of the Overadvance (together with all accrued interest and fees which remain unpaid in respect thereof). The Parent hereby agrees to provide a certificate confirming the satisfaction of the Overadvance Conditions concurrently with the request for same.

Security Agreement

(iii) The Parent acknowledges that the exercise of Calliope’s discretionary rights hereunder may result during the Term in increases or decreases in the advance percentages used in determining Accounts Availability and/or Inventory Availability and Parent hereby consents to any such increases or decreases which may limit or restrict advances requested by the Parent.

(iv) If any interest, fees, costs or charges payable to Calliope hereunder are not paid when due, Parent shall thereby be deemed to have requested, and Calliope is hereby authorized at its discretion to make and charge to the Parent’ account, a Loan as of such date in an amount equal to such unpaid interest, fees, costs or charges.

(v) If Parent at any time fails to perform or observe any of the covenants contained in this Agreement or any Ancillary Agreement, Calliope may, but need not, perform or observe such covenant on behalf and in the name, place and stead of Parent (or, at Calliope’s option, in Calliope’s name) and may, but need not, take any and all other actions which Calliope may deem necessary to cure or correct such failure (including the payment of taxes, the satisfaction of Liens, the performance of obligations owed to Account Debtors, lessors or other obligors, the procurement and maintenance of insurance, the execution of assignments, security agreements and financing statements, and the endorsement of instruments). The amount of all monies expended and all costs and expenses (including attorneys’ fees and legal expenses) incurred by Calliope in connection with or as a result of the performance or observance of such agreements or the taking of such action by Calliope shall be charged to the Parent’s account as a Revolving Loan and added to the Obligations. To facilitate Calliope’s performance or observance of such covenants by Parent, Parent hereby irrevocably appoints Calliope, or Calliope’s delegate, acting alone, as Parent’s attorney in fact (which appointment is coupled with an interest) with the right (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file in the name and on behalf of Parent any and all instruments, documents, assignments, security agreements, financing statements, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by Parent.

(vi) Calliope will account to Company Agent monthly with a statement of all Loans and other advances, charges and payments made pursuant to this Agreement, and such account rendered by Calliope shall be deemed final, binding and conclusive unless Calliope is notified by Company Agent in writing to the contrary within thirty (30) days of the date each account was rendered specifying the item or items to which objection is made.

(vii) During the Term, the Parent may borrow and prepay Loans in accordance with the terms and conditions hereof.

Until all Obligations have been fully and indefeasibly satisfied, Calliope shall retain its Lien in all Collateral. Calliope shall have, in addition to all other rights provided herein and in each Ancillary Agreement, the rights and remedies of a secured party under the UCC, and under other applicable law, all other legal and equitable rights to which Calliope may be entitled, including the right to take immediate possession of the Collateral, to require Parent to assemble the Collateral, at Parent’ joint and several expense, and to make it available to Calliope at a place designated by Calliope which is reasonably convenient to both parties and to enter any of the premises of Parent or wherever the Collateral shall be located, with or without force or process of law, and to keep and store the same on said premises until sold (and if said premises be the property of Parent, Parent agrees not to charge Calliope for storage thereof), and the right to apply for the appointment of a receiver for Parent’s property. Further, Calliope may, at any time or times after the occurrence of an Event of Default, sell and deliver all Collateral held by or for Calliope at public or private sale for cash, upon credit or otherwise, at such prices and upon such terms as Calliope, in Calliope’s sole discretion, deems advisable or Calliope may otherwise recover upon the Collateral in any commercially reasonable manner as Calliope, in its sole discretion, deems advisable. The requirement of reasonable notice shall be met if such notice is mailed postage prepaid to Company Agent at Company Agent’s address as shown in Calliope’s records, at least ten (10) days before the time of the event of which notice is being given. Calliope may be the purchaser at any sale, if it is public. In connection with the exercise of the foregoing remedies, Calliope is granted permission to use all of Parent’s Intellectual Property. The proceeds of sale shall be applied first to all costs and expenses of sale, including attorneys’

Security Agreement

fees, and second to the payment (in whatever order Calliope elects) of all Obligations. After the indefeasible payment and satisfaction in full of all of the Obligations, and after the payment by Calliope of any other amount required by any provision of law, including Section 9-608(a)(1) of the UCC (but only after Calliope has received what Calliope considers reasonable proof of a subordinate party’s security interest), the surplus, if any, shall be paid to Company Agent (for the benefit of the applicable Parent) or its representatives or to whosoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. The Parent shall remain liable to Calliope for any deficiency. Parent and Calliope acknowledge that the actual damages that would be incurred by Calliope after the occurrence of an Event of Default would be difficult to quantify and that Parent and Calliope have agreed that the fees and obligations set forth in this Section and in this Agreement would constitute fair and appropriate liquidated damages in the event of any such termination. The parties hereto each hereby agrees that the exercise by any party hereto of any right granted to it or the exercise by any party hereto of any remedy available to it (including, without limitation, the issuance of a notice of redemption, a borrowing request and/or a notice of default), in each case, hereunder or under any Ancillary Agreement shall not constitute confidential information and no party shall have any duty to the other party to maintain such information as confidential, except for the portions of such publicly filed documents that are subject to confidential treatment request made by the Parent to the SEC.

21. Waivers. To the full extent permitted by applicable law, Parent hereby waives (a) presentment, demand and protest, and notice of presentment, dishonor, intent to accelerate, acceleration, protest, default, nonpayment, maturity, release, compromise, settlement, extension or renewal of any or all of this Agreement and the Ancillary Agreements or any other notes, commercial paper, Accounts, contracts, Documents, Instruments, Chattel Paper and guaranties at any time held by Calliope on which Parent may in any way be liable, and hereby ratifies and confirms whatever Calliope may do in this regard; (b) all rights to notice and a hearing prior to Calliope’s taking possession or control of, or to Calliope’s replevy, attachment or levy upon, any Collateral or any bond or security that might be required by any court prior to allowing Calliope to exercise any of its remedies; and (c) the benefit of all valuation, appraisal and exemption laws. Parent acknowledges that it has been advised by counsel of its choices and decisions with respect to this Agreement, the Ancillary Agreements and the transactions evidenced hereby and thereby.

22. Expenses. The Parent shall pay all of Calliope’ out-of-pocket costs and expenses, including reasonable fees and disbursements of in-house or outside counsel and appraisers, in connection with (x) subject to the limitations set forth in Section 5(b)(iii), the preparation, execution and delivery of this Agreement and the Ancillary Agreements, and (y) in connection with the prosecution or defense of any action, contest, dispute, suit or proceeding concerning any matter in any way arising out of, related to or connected with this Agreement or any Ancillary Agreement. The Parent shall also pay all of Calliope’ reasonable and documented fees, charges, out-of-pocket costs and expenses, including fees and disbursements of counsel and appraisers, in connection with (a) the preparation, execution and delivery of any waiver, any amendment thereto or consent proposed or executed in connection with the transactions contemplated by this Agreement or the Ancillary Agreements, (b) Calliope’ obtaining performance of the Obligations under this Agreement and any Ancillary Agreements, including, but not limited to, the enforcement or defense of Calliope’ security interests, assignments of rights and Liens hereunder as valid perfected security interests, (c) any attempt to inspect, verify,

Security Agreement

protect, collect, sell, liquidate or otherwise dispose of any Collateral, (d) any appraisals or re-appraisals of any property (real or personal) pledged to Calliope by Parent as Collateral for, or any other Person as security for, the Obligations hereunder and (e) any consultations in connection with any of the foregoing. The Parent shall also pay Calliope’ customary bank charges for all bank services (including wire transfers) performed or caused to be performed by Calliope for Parent at Parent’s or such Subsidiary’s request or in connection with Parent’s loan account with Calliope. All such costs and expenses together with all filing, recording and search fees, taxes and interest payable by the Parent to Calliope shall be payable within five (5) days of presentment and shall be secured by the Collateral. If any tax by any Governmental Authority is or may be imposed on or as a result of any transaction between Parent and/or any Subsidiary thereof, on the one hand, and Calliope on the other hand, which Calliope is or may be required to withhold or pay (including, without limitation, as a result of a breach by Parent of Section 13(u) herein), the Parent hereby indemnifies and holds Calliope harmless in respect of such taxes, and the Parent will repay to Calliope the amount of any such taxes which shall be charged to the Parent’ account; and until the Parent shall furnish Calliope with indemnity therefor (or supply Calliope with evidence satisfactory to it that due provision for the payment thereof has been made), Calliope may hold without interest any balance standing to Parent’s credit and Calliope shall retain its Liens in any and all Collateral.

23. Assignment. Calliope may assign any or all of the Obligations together with any or all of the security therefor to any Person and any such assignee shall succeed to all of Calliope’s rights with respect thereto; provided that Calliope shall not be permitted to effect any such assignment to a competitor of Parent unless an Event of Default has occurred and is continuing. Upon such assignment, Calliope shall be released from all responsibility for the Collateral to the extent same is assigned to any transferee. Calliope may from time to time sell or otherwise grant participations in any of the Obligations and the holder of any such participation shall, subject to the terms of any agreement between Calliope and such holder, be entitled to the same benefits as Calliope with respect to any security for the Obligations in which such holder is a participant. Parent agrees that each such holder may exercise any and all rights of banker’s lien, set-off and counterclaim with respect to its participation in the Obligations as fully as though Parent were directly indebted to such holder in the amount of such participation. No Company may assign any of its rights or obligations hereunder without the prior written consent of Calliope. All of the terms, conditions, promises, covenants, provisions and warranties of this Agreement shall inure to the benefit of undersigned, and shall bind the representatives, successors and permitted assigns of Parent.

24. No Waiver; Cumulative Remedies. Failure by Calliope to exercise any right, remedy or option under this Agreement, any Ancillary Agreement or any supplement hereto or thereto or any other agreement between or among Parent and Calliope or delay by Calliope in exercising the same, will not operate as a waiver; no waiver by Calliope will be effective unless it is in writing and then only to the extent specifically stated. Calliope’s rights and remedies under this Agreement and the Ancillary Agreements will be cumulative and not exclusive of any other right or remedy which Calliope may have.

25. Application of Payments. Parent irrevocably waives the right to direct the application of any and all payments at any time or times hereafter received by Calliope from or on Parent’s behalf and Parent hereby irrevocably agrees that Calliope shall have the continuing

Security Agreement

exclusive right to apply and reapply any and all payments received at any time or times hereafter against the Obligations hereunder in such manner as Calliope may deem advisable notwithstanding any entry by Calliope upon any of Calliope’s books and records.

26. Indemnity. Parent hereby indemnifies and holds Calliope, and its respective affiliates, employees, attorneys and agents (each, an “Indemnified Person”), harmless from and against any and all suits, actions, proceedings, claims, damages, losses, liabilities and expenses of any kind or nature whatsoever (including attorneys’ fees and disbursements and other costs of investigation or defense, including those incurred upon any appeal) which may be instituted or asserted against or incurred by any such Indemnified Person as the result of credit having been extended, suspended or terminated under this Agreement or any of the Ancillary Agreements or with respect to the execution, delivery, enforcement, performance and administration of, or in any other way arising out of or relating to, this Agreement, the Ancillary Agreements or any other documents or transactions contemplated by or referred to herein or therein and any actions or failures to act with respect to any of the foregoing, except to the extent that any such indemnified liability is finally determined by a court of competent jurisdiction to have resulted solely from such Indemnified Person’s gross negligence or willful misconduct. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO PARENT OR TO ANY OTHER PARTY OR TO ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER THIS AGREEMENT OR ANY ANCILLARY AGREEMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

27. Revival. The Parent further agrees that to the extent Parent makes a payment or payments to Calliope, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy act, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, the obligation or part thereof intended to be satisfied shall be revived and continued in full force and effect as if said payment had not been made.

28. Borrowing Agency Provisions.

(a) Parent hereby irrevocably designates Company Agent to be its attorney and agent and in such capacity to borrow, sign and endorse notes, and execute and deliver all instruments, documents, writings and further assurances now or hereafter required hereunder, on behalf of Parent, and hereby authorizes Calliope to pay over or credit all loan proceeds hereunder in accordance with the request of Company Agent.

(b) The handling of this credit facility as a co-borrowing facility with a borrowing agent in the manner set forth in this Agreement is solely as an accommodation to the Parent and at their request. Calliope shall not incur any liability to Parent as a result thereof. To induce Calliope to do so and in consideration thereof, Parent hereby indemnifies Calliope and holds Calliope harmless from and against any and all liabilities, expenses, losses, damages and

Security Agreement

claims of damage or injury asserted against Calliope by any Person arising from or incurred by reason of the handling of the financing arrangements of the Parent as provided herein, reliance by Calliope on any request or instruction from Company Agent or any other action taken by Calliope with respect to this Paragraph 28.

(c) All Obligations shall be joint and several, and the Parent shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability on the part of the Parent shall in no way be affected by any extensions, renewals and forbearance granted by Calliope to Parent, failure of Calliope to give Parent notice of borrowing or any other notice, any failure of Calliope to pursue to preserve its rights against Parent, the release by Calliope of any Collateral now or thereafter acquired from Parent, and such agreement by Parent to pay upon any notice issued pursuant thereto is unconditional and unaffected by prior recourse by Calliope to Parent or any Collateral for Parent’s Obligations or the lack thereof.

(d) Parent expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which Parent may now or hereafter have against the other or other Person directly or contingently liable for the Obligations, or against or with respect to any other’s property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until all Obligations have been indefeasibly paid in full and this Agreement has been irrevocably terminated.

(e) Parent represents and warrants to Calliope that (i) Parent have common shareholders, directors and officers, (ii) the businesses and corporate activities of Parent are closely related to, and substantially benefit, the business and corporate activities of Parent, (iii) the financial and other operations of Parent are performed on a combined basis as if Parent constituted a consolidated corporate group, (iv) Parent will receive a substantial economic benefit from entering into this Agreement and will receive a substantial economic benefit from the application of each Loan hereunder, in each case, whether or not such amount is used directly by Parent and (v) all requests for Loans hereunder by the Company Agent are for the exclusive and indivisible benefit of the Parent as though, for purposes of this Agreement, the Parent constituted a single entity.

29. Notices. Any notice or request hereunder may be given to Parent, Company Agent or Calliope at the respective addresses set forth below or as may hereafter be specified in a notice designated as a change of address under this Section. Any notice or request hereunder shall be given by registered or certified mail, return receipt requested, hand delivery, overnight mail or telecopy (confirmed by mail).
