(c) Nothing contained herein or in any other Note Document, and no action taken by Lenders pursuant hereto or thereto, shall be deemed to constitute Lenders as a partnership, an association, a joint venture or any other kind of entity. The amounts payable at any time hereunder to each Lender shall be a separate and independent debt, and each Lender shall be entitled to protect and enforce its rights arising out hereof and it shall not be necessary for any other Lender to be joined as an additional party in any proceeding for such purpose.

3. Representations and Warranties of the Company and the Guarantor. In connection with the transactions provided for herein, each of the Company and Guarantor hereby represents and warrants to the Lenders that:

3.1 Corporate Existence. Such Note Party (i) is duly organized, validly existing and in good standing under the laws of the State of Delaware, (ii) has all requisite power and authority to own and operate its properties, to carry on its business as now conducted and as proposed to be conducted, to enter into this Agreement and the other Note Documents to which such Note Party is a party and to carry out the transactions contemplated thereby, and (iii) is qualified to do business and in good standing in every jurisdiction where its assets are located and wherever necessary to carry out its business and operations, except in jurisdictions where the failure to be so qualified or in good standing has not had, and could not be reasonably expected to have, a Material Adverse Effect.

3.2 Authorization. All corporate action has been taken on the part of each Note Party and each of their respective managers, members, officers, directors and stockholders necessary for the authorization, execution and delivery of this Agreement and the Notes. The issuance of the Notes will not be subject to the preemptive rights of any stockholder of the Company or member of the Guarantor that has not already been waived.

3.3 Compliance with Other Instruments. Neither the authorization, execution and delivery of this Agreement, nor the issuance and delivery of the Notes, will constitute or result in a material default or violation of any material term or provision of the Company’s current Amended and Restated Certificate of Incorporation, as amended or bylaws or the Guarantor’s Amended and Restated Limited Liability Company Agreement, as amended, or any material agreement or instrument by which the Company or the Guarantor is bound or to which its properties or assets are subject.

3.4 No Government Action. The execution, delivery and performance by such Note Party of this Agreement and the other Note Documents to which such Note Party is a party and the consummation of the transactions contemplated by this Agreement do not and will

not require any registration with, consent or approval of, or notice to, or other action to, with or by, any Governmental Authority except (i) for filings and recordings with respect to the Collateral to be made, or otherwise delivered to Lenders for filing and/or recordation and (ii) any registration, consent, approval, notice or action to the extent that the failure to undertake or obtain such registration, consent, approval, notice or action could not reasonably be expected to have a Material Adverse Effect.

3.5 Valid and Binding. This Agreement and the other Note Documents to which such Note Party is a party have been duly executed and delivered by such Note Party and are the legally valid and binding obligations of such Note Party, enforceable against such Note Party in accordance with their respective terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or limiting creditors’ rights generally or by equitable principles relating to enforceability.

3.6 No Material Adverse Effect. Since March 31, 2007, no event, circumstance or change has occurred that has caused or evidences, either in any case or in the aggregate, a Material Adverse Effect.

3.7 Compliance with Law. Each of such Note Party is in compliance with all applicable statutes, regulations and orders of, and all applicable restrictions imposed by, all Governmental Authorities, in respect of the conduct of its business and the ownership of its property, except such non-compliance that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

4. Representations and Warranties of the Lenders. In connection with the transactions provided for herein, each Lender hereby represents and warrants to the Note Parties that:

4.1 Authorization. This Agreement constitutes such Lender’s valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights and (ii) laws relating to the availability of specific performance, injunctive relief or other equitable remedies. Each Lender represents that it has full corporate power and authority to enter into this Agreement.

4.2 Purchase Entirely for Own Account. Each Lender acknowledges that this Agreement is made with Lender in reliance upon such Lender’s representation to the Note Parties that the Notes will be acquired for investment for Lender’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that such Lender has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, each Lender further represents that such Lender does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Notes.

4.3 Disclosure of Information. Each Lender acknowledges that it has received all the information it considers necessary or appropriate for deciding whether to acquire

the Notes. Each Lender further represents that it has had an opportunity to ask questions and receive answers from the Note Parties regarding the terms and conditions of the offering of the Notes.

4.4 Investment Experience. Each Lender is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Notes. If other than an individual, each Lender also represents it has not been organized solely for the purpose of acquiring the Notes.

4.5 Accredited Investor. Each Lender is an “accredited investor” within the meaning of Rule 501 of Regulation D of the Securities and Exchange Commission (the “SEC”), as presently in effect.

4.6 Restricted Securities. Each Lender understands that the Notes are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Act only in certain limited circumstances. Each Lender represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Act.

4.7 Further Limitations on Disposition. Without in any way limiting the representations and warranties set forth above, each Lender further agrees not to make any disposition of all or any portion of the Notes unless and until such Lender has received the prior written consent of the other Lender and the transferee has agreed in writing for the benefit of the Company to be bound by this Section 4 and:

(a) There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b) (i) Lender has notified the Company of the proposed disposition and has furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition and (ii) if reasonably requested by the Company, Lender shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company that such disposition will not require registration of such shares under the Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in extraordinary circumstances.

4.8 Legends. It is understood that the Notes may bear the following legend:

“THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. IT MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION

OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.”

5. State Commissioners of Corporations. THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION FOR SUCH SECURITIES PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

6. Covenants and Agreements. Each Note Party hereby covenants and agrees that:

6.1 Corporate Existence. Each Note Party will at all times preserve and keep in full force and effect its existence and all rights and franchises, licenses and permits material to its business; provided, neither any such Note Party (other than the Company with respect to existence) shall be required to preserve any such existence, right or franchise, licenses and permits if an executive officer of such Note Party shall determine that the preservation thereof is no longer desirable in the conduct of the business of such Person, and that the loss thereof is not disadvantageous in any material respect to such Person or to Lenders.

6.2 Compliance with Law. Such Note Party will comply with the requirements of all applicable laws, rules, regulations and orders of any Governmental Authority (including those relating to environmental matters), noncompliance with which could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

6.3 Liens on Collateral. Except for the security interest created by this Agreement, such Note Party shall not create or suffer to exist any Lien upon or with respect to the Collateral, and the Company shall defend the Collateral against all Persons at any time claiming any other interest therein.

6.4 Rights in Collateral. Such Note Party shall not take or permit any action which could materially impair Lenders’ rights in the Collateral except as otherwise permitted under this Agreement.

6.5 Other Information. Such Note Party shall provide any information reasonably requested by Lenders with respect to the Collateral.

Upon any such termination Lenders shall, at the Note Parties’ expense, execute and deliver to the Note Parties or otherwise authorize the filing of such documents as any Note Party shall reasonably request, including financing statement amendments to evidence such termination.

This indemnification shall be paid within thirty (30) days from the date the Lender makes written demand therefore.

(d) Within thirty (30) days after the date of any payment of Taxes, the Company shall furnish to the relevant Lender, at its address referred to in Section 13.4, the original or a certified copy of a receipt evidencing payment thereof.

(e) Without prejudice to the survival of any other agreement of the Company hereunder, the agreements and obligations of the Company contained in paragraphs (a) through (d) of this Section 12.1 shall survive the payment in full of principal and interest hereunder and under any instrument delivered hereunder.

11.2 Expenses.

(a) The Company shall forthwith on demand pay to or reimburse the Lenders for all reasonable costs, charges and expenses (including legal and other fees and translation, communication, advertisement, travel and all other out-of-pocket expenses), as evidenced by reasonable documentary evidence, incurred by it in connection with the negotiation, preparation, execution and (where relevant) registration of this Agreement and any other documentation required hereunder and the arrangement of this Agreement and any amendment hereto and any inspection, calculation, approval, consent or waiver to be conducted, made or given by the Lenders pursuant to any provision of this Agreement.

(b) The Company shall from time to time forthwith on demand pay to or reimburse the Lender for all reasonable costs, charges and expenses (including legal and other fees on a full indemnity basis and all other out-of-pocket expenses) incurred by it in exercising any of its rights or powers under this Agreement or in suing for or seeking to recover any sums due under this Agreement or otherwise preserving or enforcing its rights under this Agreement following the Company’s failure to perform its obligations hereunder or in defending any claims brought against it in respect of this Agreement.

11.3 General Indemnification. The Company shall indemnify the Lenders and their respective officers, directors, Affiliates and shareholders (the “Indemnified Parties”) against all losses, liabilities, damages, and reasonable costs and expenses which the Lenders or any other Indemnified Parties may incur as a consequence of (i) any Event of Default, (ii) the receipt or recovery by the Lenders of all or any part of any Commitment or an overdue sum relating thereto; (iii) any other breach by the Company of any of its obligations under this Agreement or in connection with this Agreement; or (iv) the consummation of the transactions contemplated by this Agreement.

11.4 Guarantor Obligation. Section 11.1, 11.2 and 11.3 shall apply to Obligations of Guarantor under Section 13 of this Agreement, mutatis mutandis.

11.5 Survival. The provisions of this Section 11 shall survive payment of full of the Obligations and termination of this Agreement.

12.1 Successors and Assigns. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties, provided, however, that neither Note Party may assign its obligations under this Agreement without the written consent of the Lenders.

The Note Parties’ agreements with each of the Lenders are separate agreements, and the sales of the Notes to each of the Lenders are separate sales.

12.9 Further Assurance. From time to time, the Note Parties shall execute and deliver to the Lenders such additional documents and shall provide such additional information to the Lenders as any Lender may reasonably require to carry out the terms of this Agreement and the Notes and any agreements executed in connection herewith or therewith.

13. Guaranty.

13.1 Guaranty of the Obligations. Guarantor hereby irrevocably and unconditionally guarantees to Lenders the due and punctual payment in full of all Obligations when the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. § 362(a) or under any other applicable bankruptcy, insolvency or similar law now or hereafter in effect) (collectively, the “Guaranteed Obligations”).

13.2 Payment by Guarantor. Guarantor hereby agrees, in furtherance of the foregoing and not in limitation of any other right which Lenders may have at law or in equity against any Guarantor by virtue hereof, that upon the failure of the Company to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. § 362(a) or under any other applicable bankruptcy, insolvency or similar law now or hereafter in effect), Guarantor will upon demand pay, or cause to be paid, in cash, to Lenders, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for the Company’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against the Company for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to Lenders as aforesaid.

13.3 Liability of Guarantor Absolute. Guarantor agrees that its obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without limiting the generality thereof, Guarantor agrees as follows:

(a) this Guaranty is a guaranty of payment when due and not of collectability. This Guaranty is a primary obligation of Guarantor and not merely a contract of surety;

(b) Lenders may enforce this Guaranty upon the occurrence of an Event of Default notwithstanding the existence of any dispute between the Company and Lenders with respect to the existence of such Event of Default;

(c) the obligations of each Guarantor hereunder are independent of the obligations of the Company and the obligations of any other guarantor of the obligations of the Company, and a separate action or actions may be brought and prosecuted against Guarantor whether or not any action is brought against the Company or any of such other guarantors and whether or not the Company is joined in any such action or actions;

(d) payment by any Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge any Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing, if a Lender is awarded a judgment in any suit brought to enforce any Guarantor’s covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit and such judgment shall not, except to the extent satisfied by such Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of the Guaranteed Obligations;

(e) Lenders, upon such terms as they deem appropriate, without notice or demand and without affecting the validity or enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of any Guarantor’s liability hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed Obligations; (iv) release, surrender, exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or modify, with or without consideration, any security for payment of the Guaranteed Obligations, any other guaranties of the Guaranteed Obligations, or any other obligation of any Person (including any other Guarantor) with respect to the Guaranteed Obligations; (v) enforce and apply any security now or hereafter held by or for the benefit of Lenders in respect hereof or the Guaranteed Obligations and direct the order or manner of sale thereof, or exercise any other right or remedy that Lenders may have against any such security, in each case as a Lender in its discretion may determine consistent herewith and any applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable, and even though such action operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Guarantor against the Company or any security for the Guaranteed Obligations; and (vi) exercise any other rights available to it under the Note Documents; and

(f) this Guaranty and the obligations of Guarantor hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or not any Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Note Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to events of default) hereof, any of the other Note Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Note Document, or any agreement relating to such other guaranty or security; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Note Documents or from the proceeds of any security for the Guaranteed Obligations, except to the extent such security also serves as collateral for indebtedness other than the Guaranteed Obligations) to the payment of indebtedness other than the Guaranteed Obligations, even though Lenders might have elected to apply such payment to any part or all of the Guaranteed Obligations; (v) each Lender’s consent to the change, reorganization or termination of the corporate structure or

existence of the Company or Guarantor and to any corresponding restructuring of the Guaranteed Obligations; (vi) any failure to perfect or continue perfection of a security interest in any collateral which secures any of the Guaranteed Obligations; (vii) any defenses, set-offs or counterclaims which the Company may allege or assert against Lenders in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury; and (viii) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an obligor in respect of the Guaranteed Obligations.

13.4 Waivers by Guarantor. Guarantor hereby waives, for the benefit of Lenders: (a) any right to require Lenders, as a condition of payment or performance by Guarantor, to (i) proceed against the Company, any other guarantor (including any other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from the Company, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of Lenders in favor of the Company or any other Guarantor or any other Person, or (iv) pursue any other remedy in the power of Lenders whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Company or any other Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Company or any other Guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon Lenders’ errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to willful misconduct, gross negligence or bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments and counterclaims, and (iv) promptness, diligence and any requirement that Lenders protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder, or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to the Company, and notices of any of the matters referred to in Section 13.3 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

13.5 Guarantor’s Rights of Subrogation, Contribution, etc. Until the Guaranteed Obligations (other than contingent indemnification obligations for which no claim has been made) shall have been indefeasibly paid in full, Guarantor hereby waives any claim, right or remedy, direct or indirect, that Guarantor now has or may hereafter have against the Company or any of its assets in connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including (a) any right of

subrogation, reimbursement or indemnification that Guarantor now has or may hereafter have against the Company with respect to the Guaranteed Obligations, (b) any right to enforce, or to participate in, any claim, right or remedy that Lenders now have or may hereafter have against the Company, and (c) any benefit of, and any right to participate in, any collateral or security now or hereafter held by Lenders. In addition, until the Guaranteed Obligations (other than contingent indemnification obligations for which no claim has been made) shall have been indefeasibly paid in full, each Guarantor shall withhold exercise of any right of contribution such Guarantor may have against any other guarantor (including any other Guarantor) of the Guaranteed Obligations. Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification Guarantor may have against the Company or against any collateral or security, and any rights of contribution Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights Lenders may have against the Company, to all right, title and interest Lenders may have in any such collateral or security, and to any right Lenders may have against such other guarantor. If any amount shall be paid to any Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations (other than contingent indemnification obligations for which no claim has been made) shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for Lenders and shall forthwith be paid over to Lenders to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof.

13.6 Subordination of Other Obligations. Any indebtedness of the Company or Guarantor now or hereafter held by Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations, and any such indebtedness collected or received by the Obligee Guarantor after an Event of Default has occurred and is continuing shall be held in trust for Lenders and shall forthwith be paid over to Lenders to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof.

13.7 Continuing Guaranty. This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been paid in full. Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations.

13.8 Authority of Guarantor or the Company. It is not necessary for Lenders to inquire into the capacity or powers of Guarantor or the Company or the officers, directors or any agents acting or purporting to act on behalf of any of them.

13.9 Financial Condition of the Company. Lenders may purchase Notes from the Company in accordance with the terms of this Agreement without notice to or authorization from Guarantor regardless of the financial or other condition of the Company at the time of any such purchase. Lenders shall not have any obligation to disclose or discuss with Guarantor its assessment, or Guarantor’s assessment, of the financial condition of the Company. Guarantor has adequate means to obtain information from the Company on a continuing basis

concerning the financial condition of the Company and their ability to perform its obligations under the Note Documents, and Guarantor assumes the responsibility for being and keeping informed of the financial condition of the Company and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Guarantor hereby waives and relinquishes any duty on the part of Lenders to disclose any matter, fact or thing relating to the business, operations or conditions of the Company now known or hereafter known by Lenders.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first above written.

		, 0000

FOR VALUE RECEIVED, the undersigned, HELIO, INC., a Delaware corporation (the “Company”), promises to pay to [EARTHLINK, INC., a Delaware corporation][SK TELECOM USA HOLDINGS, INC., a Delaware corporation] (“Lender”), the principal amount of dollars ($ ), with interest thereon from the date hereof until paid in full on the Maturity Date at a rate per annum equal to ten percent (10.00%), calculated on the basis of a 360-day year and the actual number of days elapsed. Capitalized terms used in this Note without definition shall have the meanings provided in that certain Note Purchase and Security Agreement and Guaranty entered into as of July 23, 2007 (as amended, modified and supplemented from time to time, the “Purchase Agreement”), by and between the Company, HELIO, LLC, a Delaware LLC (“Guarantor”, together with the Company, the “Note Parties”, and individually, a “Note Party”) and Lender.

The principal amount of this Note and all accrued interest thereon shall be due and payable on the Maturity Date. On the Maturity Date the entire unpaid principal balance of this Note, together with any and all accrued and unpaid interest (including, without limitation, all interest that has been added to principal hereunder) and any and all costs and expenses provided for under this Note and the other Note Documents, shall be due and payable. This Note may be prepaid at any time without penalty.

All payments under this Note shall be made to Lender or its order, in lawful money of the United States of America and in immediately available funds delivered to Lender by wire transfer of immediately available funds to Lender’s account, ABA No. , Account No. at [name and address of bank], Reference: ,] or at such other place within the United States as Lender or any holder hereof shall designate in writing for such purpose from time to time. If a payment under this Note otherwise would become due and payable on a day that is not a Business Day, the due date thereof shall be extended to the next Business Day and interest shall be payable thereon during such extension. All amounts due under this Note and the other Note Documents shall be payable without defense, set off or counterclaim.

Each payment under this Note shall be applied in the following order: (i) to the payment of costs and expenses which the Company is required to pay pursuant to the provisions of this Note or any of the other Note Documents; (ii) to the payment of accrued and unpaid interest; and (iii) to the payment of outstanding principal. Lender and each holder hereof shall have the continuing and exclusive right to apply or reverse and reapply any and all payments under this Note.

This Note is one of a series of Notes issuable to the Lenders pursuant to the terms of the Purchase Agreement and in accordance with the Lenders Commitments as described therein. All payments made to Lenders under this Note and any other Notes shall be made by the Company to each Lender in equal amounts and at the same times. No Lender shall have a priority of payment over another Lender with respect to payments due under the Notes.

Upon the occurrence of any Event of Default, the obligations under this Note shall become due and payable in accordance with the provisions of the Purchase Agreement, and Lender shall have all other remedies available under the Purchase Agreement. In addition, upon the occurrence of an Event of Default, interest shall thereafter accrue on the entire unpaid principal balance under this Note, including without limitation (x) any accrued interest which has been added to the principal balance and (y) any delinquent interest which has been added to the principal amount due under this Note pursuant to the terms hereof, at the rate set forth herein plus two percent (2.00%) per annum (on the basis of a 360-day year and the actual number of days elapsed). All interest which has become payable and is then delinquent shall, without curing the default under this Note by reason of such delinquency, be added to the principal amount due under this Note, and shall thereafter bear interest at the same rate as is applicable to principal, with interest on overdue interest to bear interest, in each case to the fullest extent permitted by applicable law, both before and after default, maturity, foreclosure, judgment and the filing of any petition in a bankruptcy proceeding. In no event shall interest be charged under this Note which would violate any applicable law. If the rate of interest provided for herein would otherwise exceed the maximum rate permitted by applicable law, then the interest rate shall be reduced to the maximum rate permitted by applicable law.

This Note is secured as set forth in the Purchase Agreement. Reference is hereby made to the Purchase Agreement for a description of the nature and extent of the security for this Note and the rights and remedies available to the holder of this Note. Nothing herein shall be deemed to limit the rights of Lender under this Note or the Note Agreement, all of which rights and remedies are cumulative.

No waiver or modification of any of the terms of this Note shall be valid or binding unless set forth in a writing specifically referring to this Note and signed by a duly authorized officer of Lender or any holder of this Note, and then only to the extent specifically set forth therein.

If any default occurs in any payment due under this Note, the Company and all guarantors and endorsers hereof, and their successors and assigns, promise to pay all costs and expenses, including attorneys’ fees, incurred by each holder hereof in collecting or attempting to collect the indebtedness under this Note, whether or not any action or proceeding is commenced. None of the provisions hereof and none of the holder’s rights or remedies under

this Note on account of any past or future defaults shall be deemed to have been waived by the holder’s acceptance of any past due installments or by any indulgence granted by the holder to the Company.

The Company and all guarantors and endorsers hereof, and their successors and assigns, hereby waive presentment, demand, diligence, protest and notice of every kind (except such notices as may be required under the Purchase Agreement), and agree that they shall remain liable for all amounts due under this Note notwithstanding any extension of time or change in the terms of payment of this Note granted by any holder hereof, any change, alteration or release of any property now or hereafter securing the payment hereof or any delay or failure by the holder hereof to exercise any rights under this Note or the Purchase Agreement. The Company and all guarantors and endorsers hereof, and their successors and assigns, hereby waive the right to plead any and all statutes of limitation as a defense to a demand under this Note to the full extent permitted by law.

This Note shall inure to the benefit of Lender, its successors and assigns and shall bind the heirs, executors, administrators, successors and assigns of the Company. Each reference herein to powers or rights of Lender shall also be deemed a reference to the same power or right of such assignees, to the extent of the interest assigned to them.

In the event that any one or more provisions of this Note shall be held to be illegal, invalid or otherwise unenforceable, the same shall not affect any other provision of this Note and the remaining provisions of this Note shall remain in full force and effect.

This Note shall be governed by and construed in accordance with the laws of the State of Georgia, without giving effect to the principles thereof relating to conflicts of law; provided, that Lender and each holder hereof reserves any and all rights it may have under federal law, including without limitation those relating to the charging of interest.
