In the event that participation in the Subsequent Advance is limited to the Lenders on Schedule I-C, such Lenders may in their sole discretion fund, in addition to their Pro Rata Share of the Advance, an amount equal to Pro Rata Share of the Advances of the Lenders not listed on Schedule I-C based on the Pro Rata Share of the Advance for each such Lender relative to the Pro Rata Share of the Advance for all the Lenders listed on Schedule I-C.

(b) Failures to Fund Commitment Amount. If Borrower has requested an Advance pursuant to Section 2.5(a) of this Agreement and all of the conditions to the Lender’s obligation to make such Advance as set forth in Section 3 have been satisfied or waived, then (A) if a Lender has nonetheless failed to advance his, her or its Pro Rata Share of an Advance (hereinafter, with respect to any applicable Lender, referred to as the “Unfunded Capital Commitment Amount”) and such failure is not remedied within five Business Days after written notice thereof is provided by Borrower to such Lender (the date of such notice, a “Default Notice Date”), in addition to any other remedies Borrower may have for breach of this Agreement, such Lender shall be assessed and shall immediately pay to Borrower a fee in an amount equal to 5% multiplied by the amount of such Lender’s Unfunded Capital Commitment Amount (such Lender hereinafter referred to as a “Defaulting Lender”), and (B) if such Defaulting Lender

- 11 -

fails to fund such Unfunded Capital Commitment Amount within ten Business Days after the proposed Default Notice Date, in addition to any other remedies Borrower may have for breach of this Agreement, such Defaulting Lender shall be assessed and shall immediately pay to Borrower an additional fee in an amount equal to 5% multiplied by the amount of such Defaulting Lender’s Unfunded Capital Commitment Amount, such Defaulting Lender shall forfeit the right to participate in any future requests for Advances made by Borrower, and the other non-Defaulting Lenders who participated in such Advance may fund their respective pro rata shares of the Unfunded Capital Commitment Amount of the Defaulting Lender based on the Pro Rata Share of the Advance for such non-Defaulting Lenders relative to the Pro Rata Share of the Advance for all the non-Defaulting Lenders. To the extent that any Defaulting Lender does not pay the fee, the amount of the outstanding Obligations for such Defaulting Lender shall be reduced by the amount of such fee. In no event shall a Lender be deemed a Defaulting Lender if the Lender is unable to make a Subsequent Advance because the Company limits participation in the Subsequent Advances to the Lenders on Schedule I-C pursuant to Section 2.1(a) above.

(c) Loans Evidenced by Notes. The obligation of Borrower to repay the unpaid principal amount of and all PIK Interest on the Loans shall be evidenced by one or more Notes.

(d) Issuance of Warrants or Common Stock. On the Funding Date for the Initial Advance, the Company issued to each Lender specified on Schedule I-A hereto, shares of Common Stock of the Company or warrants to purchase shares of Common Stock of the Company as set forth on Schedule I-A. On the Funding Date for the Second Advance, (i) for each Lender participating in the Second Advance specified on Schedule I-B hereto as purchasing shares of Common Stock, Borrower shall issue and sell to such Lender, and such Lender shall purchase from Borrower, the number of shares of Common Stock set forth opposite such Lender’s name on Schedule I-B hereto, at a purchase price of $0.58 per share, and in connection with such purchase the Lender hereby makes to Borrower the representations and warranties set forth in Section 5 of Schedule II, and (ii) for each other Lender participating in the Second Advance, the Company shall issue such Lender a Warrant covering the number of shares of Common Stock set forth opposite such Lender’s name in Schedule I-B hereto.

(e) Use of Proceeds. The proceeds of the Loans shall be used solely for working capital and other general corporate purposes of Borrower.

(f) Termination of Commitment to Lend. Notwithstanding anything in the Loan Documents, the Lenders obligation to lend the undisbursed portion of the Commitment Amount to Borrower hereunder shall terminate on the earlier of (i) at the Required Lenders’ sole election, the occurrence of any Default or Event of Default hereunder, and (ii) the applicable Commitment Termination Date.

2.2 Conversion; Payments.

(a) Lender’s Option to Convert. The outstanding balances of the Loans made hereunder shall be convertible into capital stock of Borrower on the terms and conditions set forth in Schedule II to this Agreement.

(b) Repayment of Initial Advance, Second Advance and Subsequent Advances. Subject to the terms and conditions of the Subordination Agreement, all Loans made under this Agreement (including all unpaid principal, accrued interest and PIK Interest thereon) shall be due and payable in full on the Maturity Date, except to the extent a Loan has been prepaid pursuant to Section 2.3 or converted into capital stock of Borrower pursuant to Schedule II.

- 12 -

(c) Interest on Loans. Subject to Sections 2.2(a) and (b), the Loans shall bear interest (in addition to any “original issue discount” as defined in the IRC) at the Loan Rate from the date of the applicable Advance, compounding monthly on each Interest Payment Date; provided, however, Borrower shall not pay such interest in cash but instead all such accrued and unpaid interest shall be paid in kind as described in the immediately following sentence, on each Interest Payment Date (any such interest paid in kind, the “PIK Interest”). All interest due and payable hereunder by Borrower shall be capitalized, added to the then-outstanding principal amount of the Loans as additional principal obligations hereunder on and as of such Interest Payment Date and shall automatically constitute a part of the outstanding principal amount of the Loans for all purposes hereof (including the accrual of interest thereon at the rates applicable to the Loans generally). Any determination of the principal amount outstanding under the Loans after giving effect to any PIK Interest hereunder or otherwise that is reasonably made by the Agent or the Lenders in good faith shall be prima facie evidence of the correctness of such determination in the absence of manifest error. All computations of interest (including interest at the Default Rate, if applicable) shall be based on a year of twelve 30-day months. Notwithstanding any other provision hereof, the amount of interest payable hereunder shall not in any event exceed the maximum amount permitted by the law applicable to interest charged on commercial loans.

(d) Application of Payments. All payments due to the Lenders hereunder prior to an Event of Default shall be applied as follows: (1) first, to Lenders’ Expenses then due and owing, if applicable, and (2) second, pro rata to the outstanding Loans under Advances made by the Lenders. After an Event of Default, all payments and application of proceeds shall be made as set forth in Section 9.7.

(e) Default Rate. Borrower shall pay interest at a per annum rate equal to the Default Rate on any amounts required to be paid by Borrower under this Agreement or the other Loan Documents, payable with respect to each Loan, accrued and unpaid interest, and any fees or other amounts which remain unpaid after such amounts are due. If an Event of Default has occurred and the Obligations have been accelerated (whether automatically or by Lender’s election), Borrower shall pay interest on the aggregate, outstanding accelerated balance hereunder from the date of the Event of Default until all Events of Default are cured, at a per annum rate equal to the Default Rate.

2.3 Prepayments.

(a) Mandatory Prepayment Upon an Acceleration. If a Loan is accelerated following the occurrence of an Event of Default pursuant to Section 9.1(a) hereof, then Borrower, in addition to any other amounts which may be due and owing hereunder, shall immediately pay to Lender the amount set forth in Section 2.3(b) below, as if Borrower had opted to prepay on the date of such acceleration.

(b) Subject to the terms of Section 2.3(a), no prepayments shall be permitted with respect to the Convertible Portion of the Loans (as defined in Schedule II to this Agreement). Upon ten (10) Business Days’ prior written notice to each Lender, Borrower may, at its option, at any time, prepay all or any portion of the Loans comprising only the Non-Convertible Portion of the Loans by paying to such Lender an amount equal to (i) any accrued and unpaid interest and PIK Interest on the outstanding principal balance of such Loan(s); (ii) the outstanding principal balance of such Loan(s) and (iii) all other sums, if any, that shall have become due and payable hereunder.

2.4 Other Payment Terms.

- 13 -

payable by Borrower hereunder shall be made, in immediately available funds, not later than 10:00 a.m. Pacific time, on the date on which such payment is due. Borrower shall make such payments to each Lender via wire transfer in immediately available funds or ACH or by certified check at the address set forth for such Lender in Schedule I-A hereto, as indicated by such Lender in Schedule I-A (or in a writing delivered by such Lender to Borrower from and after the Effective Date).

(b) Date. Whenever any payment is due hereunder on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of interest or fees, as the case may be.

2.5 Procedure for Making the Loans.

4.3 Duration of Security Interest. Agent’s security interest in the Collateral shall continue until the payment in full and the satisfaction of all Obligations (other than inchoate indemnity obligations) and termination of Agent and each of the other Lender’s commitment to fund the Loans, whereupon such security interest shall terminate.

Upon the occurrence of an Event of Default, to the extent permitted by law, Borrower covenants that it will not at any time insist upon or plead, or in any manner whatsoever claim or take any benefit or advantage of, any stay or extension law now or at any time hereafter in force, nor claim, take nor insist upon any benefit or advantage of or from any law now or hereafter in force providing for the valuation or appraisement of the Collateral or any part thereof prior to any sale or sales thereof to be made pursuant to any provision herein contained, or to the decree, judgment or order of any court of competent jurisdiction; nor, after such sale or sales, claim or exercise any right under any statute now or hereafter made or enacted by any state or otherwise to redeem the property so sold or any part thereof, and, to the full extent legally permitted, except as to rights expressly provided herein, hereby expressly waives for itself and on behalf of each and every Person, except decree or judgment creditors of Borrower, acquiring any interest in or title to the Collateral or any part thereof subsequent to the date of this Agreement, all benefit and advantage of any such law or laws, and covenants that it will not invoke or utilize any such law or laws or otherwise hinder, delay or impede the execution of any power herein granted and delegated to Agent, but will suffer and permit the execution of every such power as though no such power, law or laws had been made or enacted. Any sale, whether under any power of sale hereby given or by virtue of judicial proceedings, shall operate to divest all right, title, interest, claim and demand whatsoever, either at law or in equity, of Borrower in and to the Property sold, and shall be a perpetual bar, both at law and in equity, against Borrower, its successors and assigns, and against any and all Persons claiming the Property sold or any part thereof under, by or through Borrower, its successors or assigns.

9.4 Power of Attorney in Respect of the Collateral. Borrower does hereby irrevocably appoint Agent (which appointment is coupled with an interest), the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name to file any notices of security interests, financing statements and continuations and amendments thereof pursuant to the Code or federal law, as may be necessary to perfect, or to continue the perfection of Agent’s security interests in the Collateral. Borrower does hereby irrevocably appoint Agent (which appointment is coupled with an interest) on the occurrence of an Event of Default, the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name: (a) to ask, demand, collect, receive, receipt for, xxx for, compound and give acquittance for any and all rents, issues, profits, avails, distributions, income, payment draws and other sums in which a security interest is granted under Section 4 with full power to settle, adjust or compromise any claim thereunder as fully as if Agent were Borrower itself; (b) to receive payment of and to endorse the name of Borrower to any items of Collateral (including checks, drafts and other orders for the payment of money) that come into Agent’s possession or under Agent’s control; (c) to make all demands, consents and waivers, or take any other action with respect to, the Collateral; (d) in Agent’s discretion to file any claim or take any other action or proceedings, either in its own name or in the name of Borrower or otherwise, which Agent may reasonably deem necessary or appropriate to protect and preserve the right, title and interest of Agent in and to the Collateral; (e) endorse Borrower’s name on any checks or other forms of payment or security; (f) sign Borrower’s name on any invoice or xxxx of lading for any account or drafts against account debtors; (g) make, settle, and adjust all claims under Borrower’s insurance policies; (h) settle and adjust disputes and claims about the accounts directly with account debtors, for amounts and on terms Agent determines reasonable; (i) transfer the Collateral into the name of Agent or a third party as the Code permits; and (j) to otherwise act with respect thereto as though Agent were the outright owner of the Collateral.

9.5 Lenders’ Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Agent, with the written consent or at the written direction of the Required Lenders, may do any or all of the following: (a) make payment of the same or any part thereof; or (b) obtain and maintain insurance policies of the type discussed in Section 6.8 of this Agreement, and take any action with respect to such policies as Agent deems prudent. Any amounts paid or deposited by Agent shall constitute Lenders’

- 31 -

Expenses (and payable and reimbursable to Agent), shall be immediately due and payable, shall bear interest at the Default Rate and shall be secured by the Collateral. Any payments made by Agent or any Lender shall not constitute an agreement by Agent or such Lender to make similar payments in the future or a waiver by Agent or such Lender of any Event of Default under this Agreement. Borrower shall pay all reasonable fees and expenses, including without limitation, Lenders’ Expenses, incurred by Agent or any Lender in the enforcement or attempt to enforce any of the Obligations hereunder not performed when due.

9.6 Remedies Cumulative. Each of Agent’s and each Lender’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Agent and each Lender shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Agent or any Lender of one right or remedy shall be deemed an election, and no waiver by Agent or such Lender of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Agent or any Lender shall constitute a waiver, election, or acquiescence by it.

9.7 Application of Collateral Proceeds. The proceeds and/or avails of the Collateral, or any part thereof, and the proceeds and the avails of any remedy hereunder (as well as any other amounts of any kind held by Agent or any Lender, at the time of or received by Agent or any Lender after the occurrence of an Event of Default hereunder) shall be paid to and applied as follows:

(a) First, to the payment of out-of-pocket costs and expenses, including all amounts expended to preserve the value of the Collateral, of foreclosure or suit, if any, and of such sale and the exercise of any other rights or remedies, and of all proper fees, expenses, liability and advances, including reasonable legal expenses and attorneys’ fees, incurred or made hereunder by Agent and the Lenders, including, without limitation, Lenders’ Expenses;

(b) Second, to the payment to each Lender, on a ratable basis, of the amount then owing or unpaid on the Loans for any accrued and unpaid interest, the amounts which would have otherwise come due under Section 2.3(b)(ii), if the Loans had been voluntarily prepaid, the principal balance of the Loans, and all other Obligations with respect to the Loans held by such Lender (provided, however, if such proceeds shall be insufficient to pay in full the whole amount so due, owing or unpaid upon the Loans, then to the unpaid interest thereon, then to the amounts which would have otherwise come due under Section 2.3(b)(ii), if the Loans had been voluntarily prepaid, then to the principal balance of the Loans, and then to the payment of other amounts then payable to Lender under any of the Loan Documents); and

(c) Third, to the payment of the surplus, if any, to Borrower, its successors and assigns, or to the Person lawfully entitled to receive the same.

9.8 Reinstatement of Rights. If Agent and any Lender shall have proceeded to enforce any right under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely, then and in every such case (unless otherwise ordered by a court of competent jurisdiction), Agent and any such Lender shall be restored to its former position and rights hereunder with respect to the Property subject to the security interest created under this Agreement.

10. Waivers; Indemnification.

10.1 Demand; Protest. Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity,

- 32 -

release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by the Lenders on which Borrower may in any way be liable.

10.2 Lender’s Liability for Collateral. So long as Agent or any Lender complies with its obligations, if any, under the Code, neither Agent nor any Lender shall in any way or manner be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause other than Lender’s gross negligence or willful misconduct; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person whomsoever. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower.

10.3 Indemnification and Waiver. Whether or not the transactions contemplated hereby shall be consummated:

(a) General Indemnity. Borrower agrees upon demand to pay or reimburse each Lender for all liabilities, obligations and out-of-pocket expenses, including all Lenders’ Expenses and reasonable fees and expenses of counsel for Lender from time to time arising in connection with the enforcement or collection of sums due under the Loan Documents, and in connection with any amendment or modification of the Loan Documents or any “work-out” in connection with the Loan Documents. Borrower shall indemnify, reimburse and hold each Lender, and each of its respective successors, assigns, agents, attorneys, officers, directors, equity holders, servants, agents and employees (each an “Indemnified Person”) harmless from and against all liabilities, losses, damages, actions, suits, demands, claims of any kind and nature (including claims relating to environmental discharge, cleanup or compliance), all costs and expenses whatsoever to the extent they may be incurred or suffered by such Indemnified Person in connection therewith (including reasonable attorneys’ fees and expenses), fines, penalties (and other charges of any applicable Governmental Authority), licensing fees relating to any item of Collateral, damage to or loss of use of property (including consequential or special damages to third parties or damages to Borrower’s property), or bodily injury to or death of any person (including any agent or employee of Borrower) (each, a “Claim”), directly or indirectly relating to or arising out of the use of the proceeds of the Loans or otherwise, the falsity of any representation or warranty of Borrower or Borrower’s failure to comply with the terms of this Agreement or any other Loan Document. The foregoing indemnity shall cover, without limitation, (i) any Claim in connection with a design or other defect (latent or patent) in any item of equipment or product included in the Collateral, (ii) any Claim for infringement of any patent, copyright, trademark or other intellectual property right, (iii) any Claim resulting from the presence on or under or the escape, seepage, leakage, spillage, discharge, emission or release of any Hazardous Materials on the premises owned, occupied or leased by Borrower, including any Claims asserted or arising under any Environmental Law, (iv) any Claim for negligence or strict or absolute liability in tort, or (v) any Claim asserted as to or arising under any Account Control Agreement or any Landlord Agreement; provided, however, Borrower shall not indemnify any Lender for any liability incurred by such Lender as a direct and sole result of such Lender’s gross negligence or willful misconduct. Such indemnities shall continue in full force and effect, notwithstanding the expiration or termination of this Agreement. Upon any Lender’s written demand, Borrower shall assume and diligently conduct, at its sole cost and expense, the entire defense of such Lender, each of its members, partners, and each of their respective, agents, employees, directors, officers, equity holders, successors and assigns against any indemnified Claim described in this Section 10.3(a). Borrower shall not settle or compromise any Claim against or involving any Lender without first obtaining such Lender’s written consent thereto, which consent shall not be unreasonably withheld.

(b) Waiver. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT OR ANYWHERE ELSE, BORROWER AGREES THAT IT

- 33 -

SHALL NOT SEEK FROM LENDER UNDER ANY THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS), ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES.

(c) Survival; Defense. The obligations in this Section 10.3 shall survive payment of all other Obligations pursuant to Section 12.8. At the election of any Indemnified Person, Borrower shall defend such Indemnified Person using legal counsel satisfactory to such Indemnified Person in such Person’s reasonable discretion, at the sole cost and expense of Borrower. All amounts owing under this Section 10.3 shall be paid within thirty (30) days after written demand.

13. Relationship of Parties. Borrower and each Lender acknowledge, understand and agree that the relationship between Borrower, on the one hand, and such Lender, on the other, is, and at all time shall remain solely that of a borrower and lender. Such Lender shall not under any circumstances be construed to be a partner or a joint venturer of Borrower or any of its Affiliates; nor shall such Lender under any circumstances be deemed to be in a relationship of confidence or trust or a fiduciary relationship with Borrower or any of its Affiliates, or to owe any fiduciary duty to Borrower or any of its Affiliates.

SCHEDULE II

Terms for Conversion of Outstanding Balance on Advances

1. DEFINITION. The following definitions shall apply for all purposes of this Schedule II to the Agreement:

“Actual Conversion Amount” means the amount of the outstanding balance of a Loan (including for clarity the aggregate outstanding principal and all accrued interest and PIK Interest in respect of such Loan) converted into Conversion Stock pursuant to Section 2 of this Schedule II.

“Actual Conversion Date” means the date on which any of the outstanding balance of a Loan is converted pursuant to Section 2 of this Schedule II.

“Conversion Price” means the lower of (a) $0.98 or (b) the lowest per share selling price of any shares of capital stock sold by Borrower following the Effective Date, other than shares of capital stock sold in a transaction that would be exempt from the anti-dilution rights of the holders of Borrower’s preferred stock pursuant to clauses (i) through (viii) of Article V, Section 5.8 of Borrower’s certificate of incorporation, as in effect on the Effective Date. The Conversion Price is subject to adjustment as provided herein.

“Conversion Stock” means Borrower’s Common Stock. The number and character of shares of Conversion Stock are subject to adjustment as provided in Section 4 of this Schedule II and the term “Conversion Stock” shall include the stock and other securities and property that are, on the Actual Conversion Date, receivable or issuable upon such conversion of a Note in accordance with Section 4 of this Schedule II.

“Dividend Event” has the meaning set forth in Section 4.2 of this Schedule II.

“Lost Note Documentation” means documentation reasonably satisfactory to Borrower with regard to a lost or stolen Note, including, if required by Borrower, an affidavit of lost note and an indemnification agreement by the respective Lender in favor of Borrower with respect to such lost or stolen Note.

“Maximum Conversion Amount” means:

(a) with respect to any Loan comprising part of the Initial Advance or Second Advance, the amount of the entire outstanding balance of such Loan (including for clarity the aggregate outstanding principal and all accrued interest and PIK Interest in respect of such Loan), and

(b) with respect to any Loan comprising part of a Subsequent Advance, an amount equal to fifty percent (50%) of the initial outstanding principal amount of such Loan plus all accrued interest and PIK Interest in respect of such portion of the principal amount (the outstanding balance of the Initial Advance, the Second Advance and convertible portion of the Subsequent Advances being sometimes referred to herein as the “Convertible Portion of the Loans” and the non-convertible portion of the Subsequent Advances being referred to herein as the “Non-Convertible Portion of the Loans”)); provided that if the Maturity Date occurs by reason of an IPO and either (i) Borrower is prohibited from paying, (ii) the Lenders are otherwise prohibited from receiving or accepting payment for, or (iii) Borrower otherwise fails to pay when due the outstanding balance on any Subsequent Advance due in connection with the consummation of the IPO, including without limitation by reason of a default or event of default under the Senior Secured Loan and Security Agreement and/or the Senior Subordinated Secured Loan and Security

1

Agreement or the application of the terms of the Subordination Agreement, then the “Maximum Conversion Amount” with respect to the foregoing clause (b) shall be deemed to be one hundred percent (100%) of the amount of the outstanding balance of such Loans.

“Reorganization Event” has the meaning set forth in Section 4.3 of this Schedule II.

“Stock Event” has the meaning set forth in Section 4.4 of this Schedule II.

2. CONVERSION.

2.1 Optional Conversion Prior to Repayment. Upon the election of a Lender with respect to any Loan made by it, which election shall be exercised by written notice from such Lender given to Borrower prior to Borrower’s repayment in full of the outstanding balance of such Loan (which election, in the event the Maturity Date is anticipated to occur due to the consummation of a Change in Control or IPO, may at Lender’s option be made contingent upon the completion of such Change in Control or IPO), the entire Maximum Conversion Amount of such Loan, or any portion thereof as specified in such election of the Lender, shall be cancelled and converted into that number of shares of Conversion Stock obtained by dividing (i) the entire Maximum Conversion Amount of such Loan or portion thereof specified by the Lender, by (ii) the Conversion Price.

2.2 Timing of Conversion; Tender of Note for Conversion. In connection with a conversion pursuant to Section 2.1, a Lender shall deliver the original Note corresponding to such Loan (or Lost Note Documentation, if applicable) to Borrower. If a Lender elects to convert only a portion of the Loan represented by a Note, then promptly after (and in any event within 7 days after) receipt of the original Note (or Lost Note Documentation, if applicable) Borrower shall re-issue such Lender a new Note reflecting the portion of such Loan that was not converted and remains outstanding. If a Lender delivers written notice of an election to convert a Loan (or portion thereof) within the time period specified in Section 2.1, the conversion of such Loan (or portion thereof) into Conversion Stock shall be deemed to occur upon the earlier of (i) the date of such Lender’s written notice (unless the Lender has elected to make conversion of the Loan contingent on the consummation of a Change in Control or IPO) and (ii) immediately prior to the Maturity Date, without regard to whether Lender has then delivered to Borrower the Note(s) corresponding to the Loan so converted (or the Lost Note Documentation where applicable) or executed any other documents.

2.3 Termination of Rights. Except for the right to obtain certificates representing the Conversion Stock under Section 3 below, all rights with respect to a Loan (or portion thereof) converted pursuant this Section 2 shall terminate upon the effective conversion of such Loan (or portion thereof) as provided in Section 2.1 above.

3. CERTIFICATES; NO FRACTIONAL SHARES. Subject to Section 2.2 above, as soon as practicable after conversion of a Loan pursuant to Section 2.1 above, Borrower at its expense will register such shares of Conversion Stock in Borrower’s stockholder register in the name of the applicable Lender and will cause to be issued in the name of such Lender and to be delivered to such Lender, a certificate or certificates for the number of shares of Conversion Stock to which such Lender shall be entitled upon such conversion (bearing such legends as may be required by applicable state and federal securities laws in the opinion of legal counsel of Borrower, by Borrower’s Certificate of Incorporation and Bylaws and by any agreement between Borrower and such Lender), together with any other securities and property to which such Lender is entitled upon such conversion under the terms of such Loan; provided that in the event that the conversion is effected upon an IPO, Borrower may issue uncertificated shares. No fractional shares shall be issued upon conversion of a Loan. If upon any conversion of a Loan, a fraction of a share would otherwise be issued, then in lieu of such fractional share, Borrower shall

pay to the applicable Lender an amount in cash equal to such fraction of a share multiplied by the applicable Conversion Price.

4. ADJUSTMENT PROVISIONS. So long as any of the aggregate balance of the Loans remains outstanding, the number and character of shares of Conversion Stock issuable upon conversion of a Loan upon an Actual Conversion Date and, to the extent set forth in this Section 4, the Conversion Price therefor, are each subject to adjustment upon each occurrence of an adjustment event described in Sections 4.1 through 4.4 below occurring between the Effective Date and such Actual Conversion Date:

4.1 Adjustment for Stock Splits and Stock Dividends. The Conversion Price and the number of shares of Conversion Stock shall each be proportionally adjusted to reflect any stock dividend, stock split, reverse stock split or other similar event affecting the number of outstanding shares of Conversion Stock without the payment of consideration to Borrower therefor at any time before an Actual Conversion Date.

4.2 Adjustment for Other Dividends and Distributions. If Borrower shall make or issue, or shall fix a record date for the determination of eligible holders of its capital stock entitled to receive, a dividend or other distribution payable with respect to the Conversion Stock that is payable in securities of Borrower (other than issuances with respect to which adjustment is made under Section 4.1 or 4.3 of this Schedule II), or in assets (other than cash dividends) (each, a “Dividend Event”), and such dividend or other distribution is actually made, then, and in each such case, a Lender, upon conversion of an Actual Conversion Amount at any time after such Dividend Event, shall receive, in addition to the Conversion Stock issuable upon such conversion of its Note, the securities or other assets that would have been issuable to such Lender had such Lender, immediately prior to such Dividend Event, converted such Actual Conversion Amount into Conversion Stock.

4.3 Adjustment for Consolidation or Merger. If Borrower shall consolidate with or merge into one or more other corporations or other entities (and for clarity the Loans shall not have already been repaid and/or are not being repaid in connection with the consummation of such consolidation or merger), and pursuant to such consolidation or merger stock, other securities or other property is issued or paid to holders of Conversion Stock (each, a “Reorganization Event”), then, and in each such case, a Lender, upon conversion of an Actual Conversion Amount after the consummation of such Reorganization Event, shall be entitled to receive (in lieu of the stock or other securities and property that such Lender would have been entitled to receive under the terms of its Note upon such conversion but for such Reorganization Event), the stock or other securities or property that such Lender would have been entitled to receive upon the consummation of such Reorganization Event if, immediately prior to such Reorganization Event, such Lender had converted such Actual Conversion Amount into Conversion Stock, all subject to further adjustment as provided herein, and the successor corporation or other successor entity in such Reorganization Event shall duly execute and deliver to such Lender a supplement to such Note acknowledging such corporation’s or other entity’s obligations under such Note; and in each such case, the terms of such Note shall be applicable to the shares of stock or other securities or property receivable upon the conversion of such Note after the consummation of such Reorganization Event.

4.4 Conversion of Stock. In each case not otherwise covered in Section 4.3 above where (i) all the outstanding Conversion Stock is converted, pursuant to the terms of Borrower’s Certificate of Incorporation, into other securities or property, or (ii) the Conversion Stock otherwise ceases to exist or to be authorized under Borrower’s Certificate of Incorporation (each a “Stock Event”), then Lender, upon conversion of this Note at any time after such Stock Event, shall receive, in lieu of the number of shares of Conversion Stock that would have been issuable upon conversion of this Note immediately prior to such Stock Event, the stock and other securities and property that Lender would

have been entitled to receive upon the Stock Event, if immediately prior to such Stock Event, Lender had converted the Actual Conversion Amount into Conversion Stock.

4.5 Notice of Adjustments. Borrower shall promptly give written notice of each adjustment of the Conversion Price or the number or type of shares of Conversion Stock or other securities or property issuable upon conversion of a Note that is required under this Section 4. The notice shall describe the adjustment or readjustment and show in reasonable detail the facts on which the adjustment or readjustment is based.

4.6 Reservation of Stock. If the number of shares of Conversion Stock or other securities authorized and reserved for issuance upon conversion of the Notes shall not be sufficient to effect the conversion of the aggregate Maximum Conversion Amounts of the Notes, then Borrower shall take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Conversion Stock or other securities issuable upon conversion of the Notes as shall be sufficient for such purpose.

5. REPRESENTATIONS AND WARRANTIES AND COVENANTS OF THE LENDERS

5.1 Purchase for Own Account. Each Lender represents that it is acquiring the Notes, the Warrants, the Conversion Stock and the Common Stock, as the case may be (collectively, the “Securities”), solely for its own account and beneficial interest for investment and not for sale or with a view to distribution of the Securities or any part thereof, has no present intention of selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the same, and does not presently have reason to anticipate a change in such intention. Notwithstanding the foregoing, KPCB Holdings, Inc. is acquiring the Securities as a nominee.

5.2 Information and Sophistication. Without lessening or obviating the representations and warranties of the Borrower set forth in Section 5 of the Loan Agreement, each Lender hereby: (i) acknowledges that it has received all the information it has requested from the Borrower and it considers necessary or appropriate for deciding whether to acquire the Securities, (ii) represents that it has had an opportunity to ask questions and receive answers from the Borrower regarding the terms and conditions of the offering of the Securities and to obtain any additional information necessary to verify the accuracy of the information given the Lender and (iii) further represents that it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risk of this investment.

5.3 Ability to Bear Economic Risk. Each Lender acknowledges that investment in the Securities involves a high degree of risk, and represents that it is able, without materially impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment.

5.4 Further Limitations on Disposition. Without in any way limiting the representations set forth above, each Lender further agrees not to make any disposition of all or any portion of the Securities unless and until:

(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) The Lender shall have notified the Borrower of the proposed disposition and shall have furnished the Borrower with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Borrower, such Lender shall have furnished the

Borrower with an opinion of counsel, reasonably satisfactory to the Borrower, that such disposition will not require registration under the Act or any applicable state securities laws, provided that no such opinion shall be required for dispositions in compliance with Rule 144, except in unusual circumstances.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such registration statement or opinion of counsel shall be required: (i) for any transfer of any Conversion Stock, Common Stock and shares of Common Stock issued or issuable upon exercise of any Warrant in compliance with SEC Rule 144 or Rule 144A, or (ii) for any transfer of any Conversion Stock, Common Xxxxxxx shares of Common Stock issued or issuable upon exercise of any Warrant that is a partnership, limited liability company or corporation to (A) a partner (or retired partner) or member (or retired member) of such Lender in accordance with partnership or limited liability company interests or stock or other equity interests of such entity or (B) an Affiliate of such Lender that is a limited liability company or corporation, or (iii) for any transfers by gift, will or intestate succession to any spouse or lineal descendants or ancestors, if all transferees agree in writing to be subject to the terms hereof to the same extent as if they were Lenders hereunder.

5.5 Accredited Investor Status. Each Lender is an “accredited investor” as such term is defined in Rule 501 under the Act.

5.7 Lock-Up Agreement. Each Lender acknowledges that the Conversion Stock, Common Stock and any shares of Common Stock issued upon exercise of the Warrant held by such Lender shall be bound by the lock-up provisions set forth in Section 1.13 of the Amended and Restated Investors’ Rights Agreement dated as of March 15, 2010 by and between the Borrower and certain investors in the Borrower, to which Lender, or an Affiliate of the Lender, is a party.

SCHEDULE III

Terms relating to Agent and Agency

Each of the Lenders hereby irrevocably appoints the Agent as its agent and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. Without limiting the generality of the foregoing, the Agent is hereby expressly authorized to execute, and thereby to bind each Lender to, (i) any and all documents (including releases) with respect to the Collateral and the rights of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the Loan Documents and (ii) the Subordination Agreement.

The person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such person and its affiliates may provide debt financing, equity capital or other services (including financial advisory services) to any of the Lenders (or any person engaged in similar business as that engaged in by any of the Lenders) as if such person was not performing the duties specified herein, and may accept fees and other consideration from any of the Lenders for services in connection with this Agreement and otherwise without having to account for the same to the Lenders.

Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that such Agent is instructed in writing to exercise by the Required Lenders, and (c) except as expressly set forth in the Loan Documents, Agent shall not have any duty to disclose, nor shall it be liable for the failure to disclose, any information relating to Borrower or any of the Subsidiaries that is communicated to or obtained by the person serving as Agent and/or Collateral Agent or any of its Affiliates in any capacity. Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders or in the absence of its own gross negligence or willful misconduct. Agent shall not be deemed to have knowledge of any Default unless and until written notice thereof is given to such Agent by Borrower or a Lender, and Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Section 3 of the Loan Agreement or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to such Agent.

Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper person. Agent may also rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon. Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by it. Agent and any such sub-agent may perform any and all its duties and

exercise its rights and powers by or through their respective Affiliates. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Affiliates of each Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Credit Facilities as well as activities as Agent.

Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, if no Event of Default has occurred and is continuing, with the consent of the Borrower which shall not be unreasonably conditioned, withheld or delayed, the Required Lenders shall have the right, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent which shall be one of the other Lenders under this Agreement, or an Affiliate of any such Lender. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The Borrower shall pay the reasonable fees of a successor Agent. After an Agent’s resignation hereunder, the provisions of this Schedule III shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Affiliates in respect of any actions taken or omitted to be taken by any of them while acting as Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

FORM OF LEGAL OPINION OF BORROWER’S COUNSEL

November 16, 2011

To the persons and entities listed on Schedule I-B of

the Subordinated Convertible Loan Facility

and Security Agreement

Re: Subordinated Convertible Loan Facility and Security Agreement

Ladies and Gentlemen:

We have acted as counsel for Enphase Energy, Inc., a Delaware corporation (“Borrower”), in connection with the extension of loans to the Borrower pursuant to that certain Amended and Restated Subordinated Convertible Loan Facility and Security Agreement dated as of November 16, 2011 (the “Loan Facility Agreement”), by and among the Borrower, the lenders listed on Schedule I-A to the Loan Facility Agreement (each a “Lender” and collectively the “Lenders”), and KPCB Holdings, Inc., as Nominee, as a Lender pursuant to the Loan Facility Agreement and in its capacity as Agent on behalf of the Lenders.

This opinion is furnished to you at the request and on behalf of the Borrower pursuant to Section 3.3(k) of the Loan Facility Agreement. For convenience, unless otherwise indicated, all capitalized terms used in this opinion letter are to have the respective meanings given to them in the Loan Facility Agreement.

In connection with this opinion, we have examined the following documents, each of which is dated as of November 16, 2011 unless another date is specified below:

1. the Loan Facility Agreement;

2. the warrants to purchase common stock of the Company issued on November 16, 2011 pursuant to the Loan Facility Agreement (the “Warrants”);

3. the secured convertible promissory notes issued by the Company on November 16, 2011 pursuant to the Loan Facility Agreement (the “Notes”);

4. the Amended and Restated Certificate of Incorporation of Borrower, as filed with the Secretary of State of the State of Delaware on March 15, 2010, and as amended by the Certificate of Amendments filed on May 21, 2010 and June 14, 2011, as certified by the Secretary of the Borrower not to have been further amended, modified, supplemented or restated since such date and to be in full force and effect as of the date of this opinion letter (the “Charter”); and

5. the Bylaws of Borrower as certified by the Secretary of Borrower not to have been amended, modified, supplemented or restated since such date and to be in full force and effect as of the date of this opinion letter.

Items (1) through (3) above will from time to time hereinafter be collectively referred to as the “Loan Documents”. Items (4) and (5) above are hereinafter collectively referred to as the “Organizational Documents.”

In connection with this opinion, we have examined and relied upon the representations and warranties as to factual matters contained in and made pursuant to the Loan Documents by the various parties and upon originals or copies certified to our satisfaction of such records, agreements, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. As to certain factual matters, we have relied upon certificates of an officer of the Borrower and have not sought to independently verify such matters.

Where we render an opinion “to our knowledge” or concerning an item “known to us” or our opinion otherwise refers to our knowledge, it is based solely upon (a) an inquiry of attorneys currently within this firm who worked on this transaction and (b) receipt of a certificate executed by an officer of the Borrower covering such matters. We have made no further investigation.

In rendering the opinions expressed below, we have assumed, without investigation:

(a) the genuineness and authenticity of all signatures on original written documents (except that such assumption is not made with respect to the signatures of the person executing the Loan Documents on behalf of the Borrower);

(b) the authenticity of all documents submitted to us as originals;

(c) the conformity to originals of all documents submitted to us as copies;

(d) the accuracy, completeness and authenticity of certificates of public officials;

(e) the due incorporation or formation, valid existence, good standing and the corporate or similar power to enter into, and perform in accordance with their respective terms, the Loan Documents, of all parties thereto (except that such assumption is not made with respect to the Borrower);

(f) the due authorization, execution and delivery of all documents (except that such assumption is not made with respect to the due authorization, execution and delivery of the Loan Documents by the Borrower), in each case where the authorization, execution and delivery thereof by such parties are prerequisites to the effectiveness of such documents;

(g) the legal capacity of all individuals executing and delivering documents to so execute and deliver;

(h) that the Loan Documents are obligations binding upon all parties thereto (except that such assumption is not made with respect to the Borrower); and

(i) there are no extrinsic agreements or understandings among the parties to the Loan Documents that would modify or interpret the terms of the Loan Documents or the respective rights or obligations of the parties thereunder.

We have also assumed, without investigation, that each party to the Loan Documents other than the Company has filed any required California franchise or income tax returns and has paid any required California franchise, income or similar taxes.

Our opinion is expressed only with respect to the federal laws of the United States of America, the laws of the State of California and the General Corporation Law of the State of Delaware. Opinions of counsel in Delaware have not been obtained. We express no opinion as to whether the laws of any particular jurisdiction apply, and no opinion to the extent that the laws of any jurisdiction other than those identified above are applicable to the subject matter hereof.

Our opinion in paragraph 1 below with respect to the good standing of the Company and with respect to the Company’s qualifications to do business as a foreign corporation, we have relied solely upon an examination of certificates of the Secretaries of State of the indicated jurisdictions as of a recent date. We have made no further investigation.

We express no opinion relative to usury, or the applicability or effect of (a) any law, rule or regulation relating to securities or to the sale or issuance thereof, (b) any pension, employee benefit or tax laws, including, without limitation, the Internal Revenue Code and the Employee Retirement Income Security Act of 1974, as amended, and other similar laws, statutes, rules, acts, regulations or ordinances, or any decrees or decisional law with respect thereto, (c) any federal or state law, rule or regulation relating to antitrust, unfair competition or trade practice laws, (d) compliance with fiduciary duties by the Company’s Board of Directors or stockholders, (e) any federal or state environmental, land use, safety or similar law, laws or regulations, (f) compliance with any antifraud law, rule or regulation relating to securities or the sale or issuance thereof, (g) compliance with safe harbors for disinterested Board of Director or stockholder approvals; (h) compliance with state securities or blue sky laws except as specifically set forth below; (i) compliance with the Investment Company Act of 1940; (j) compliance with laws that place limitations on corporate distributions; (k) Regulations T, U or X of the Board of Governors of the Federal Reserve System; or (l) local law.

With regard to our opinion in paragraph 4 below with respect to securities of Borrower to be issued after the date hereof, we express no opinion as to whether, notwithstanding its current reservation of shares of Common Stock, future issuances of securities of Borrower and/or antidilution adjustments to outstanding securities of Borrower will cause the Warrants to be exercisable for more Shares (as defined in the Warrants) than the number of shares of Common Stock that then remain authorized but unissued.

With regard to our opinion in paragraph 7 concerning exemption from registration, our opinion is expressed only with respect to the offer and sale of the Notes, Warrants and shares of Common Stock without regard to any offers or sales of other securities occurring prior to or subsequent to the date hereof.

On the basis of the foregoing, in reliance thereon, and with the foregoing qualifications, we are of the opinion that:

1. Borrower has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware, and is duly qualified and authorized to do business in the State of California.

2. Borrower has the requisite corporate power to execute and deliver the Loan Documents and to perform its obligations thereunder.

3. The Loan Documents have been duly authorized, executed and delivered by Borrower and constitute valid, legal and binding agreements of Borrower that is party thereto, and are enforceable in accordance with their terms.

4. The Common Stock purchased by certain of the Lenders on the date of the Second Advance, the Shares (as defined in the Warrants) issuable pursuant to exercise of the Warrants, and the Conversion Stock issuable upon conversion of the Notes, assuming conversion as of the date hereof, have been duly authorized and reserved for issuance by Borrower and, when issued in accordance with the terms of the Loan Facility Agreement and Warrants, will be validly issued, fully paid and nonassessable.

5. Neither the execution nor the delivery by Borrower of the Loan Documents will result in a violation of the Organizational Documents as in effect on the date hereof, or violate, in any material respect (i) any California or United States federal law, governmental rule or regulation, which in our experience is typically applicable to transactions of the nature contemplated by the Loan Documents, or (ii) any order, writ, judgment, injunction, decree, determination or award which has been entered against Borrower and of which we are aware.

6. To our knowledge, there is no action, suit, investigation or proceeding pending against Borrower in any court or before any governmental commission, agency, board or authority that questions the validity of the Loan Documents.

7. Assuming the accuracy of the representations and warranties of the Lenders set forth in Section 5 of Schedule II to the Loan Facility Agreement, the offer and sale of the Common Stock purchased by certain of the Lenders on the date of the Second Advance and the issuance of the Notes and the Warrants on the date of the Second Advance are exempt from the registration requirements of the Securities Act of 1933, as amended, subject to the timely filing of a Form D pursuant to Securities and Exchange Commission Regulation D.

The opinions expressed herein are subject to and limited by the following additional qualifications, assumptions, limitations and exceptions:

(a) The legality, validity, binding nature and enforceability of Borrower’s obligations under the Loan Documents may be subject to or limited by (i) general equity principles and the limitations on the availability of equitable relief, including, without limitation, specific performance, concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether in a proceeding in equity or at law; (ii) the effect of applicable bankruptcy, insolvency, fraudulent transfer or conveyance, reorganization, arrangement, dissolution, moratorium or other similar laws relating to or affecting creditors’ rights generally; (iii) limitations created by or arising under statute or case law on (A) a debtor’s or guarantor’s ability to waive rights or benefits or (B) a party’s ability to enforce its rights due to a waiver or other conduct by the party which is inconsistent with its intent to enforce such rights; and (iv) limitations imposed by law and public policy on indemnification or exculpation.

(b) We express no opinion as to the enforceability of “choice of forum” or “consent to jurisdiction” or “waiver of jury trial” provisions contained in any of the Loan Documents.

(c) Our opinions are subject to the effect of the limitations imposed by the California Uniform Commercial Code relating to or affecting the rights and remedies available to secured creditors.

(d) We express no opinion as to the enforceability of provisions in the Loan Documents (a) imposing late charges, premiums, penalties, or forfeitures, (b) imposing an increase in interest rate upon delinquency in payment or the occurrence of a default or (c) requiring any prepayment fee, breakage or yield maintenance charges, including, without limitation, a requirement for the payment thereof upon the occurrence of a default under the Loan Documents for whatever cause or upon acceleration of the Obligations.

(e) We express no opinion as to the creation, relative priority or perfection of any security interest, lien, charge or other encumbrance purported to be created by or under the Loan Documents, nor as to the effect of any such security interest, lien, charge or other encumbrance on any rights or interests, if any, of any Person.

(f) We have assumed that the Lender (i) will act fairly, in good faith and in a commercially reasonable and prudent manner in exercising its rights and (ii) will not trespass or commit any breach of peace in any taking of possession of any of the Collateral.

Our opinions set forth above are limited to the matters expressly set forth in this opinion letter, and no opinion is implied or may be inferred beyond the matters expressly stated. This opinion speaks only as to law and facts in effect or existing as of the date hereof and we undertake no obligation or responsibility to update or supplement this opinion to reflect any facts or circumstances that may hereafter come to our attention or any changes in law which may hereafter occur.

[SIGNATURE PAGE FOLLOWS]

This opinion letter is intended solely for the benefit of the addressees of this letter, and is not to be made available to or relied upon by any other Person, firm or entity without our prior written consent.

Very truly yours,
