Borrower and Lender intend legally to agree upon the rate or rates of interest (and the other amounts paid in connection herewith) and manner of payment stated within this Note; provided, however, that anything contained herein to the contrary notwithstanding, if said interest rate or rates of interest (or other amounts paid in connection herewith) or the manner of payment exceeds the maximum allowable under applicable law, then, ipso facto as of the date of this Note, Borrower is and shall be liable only for the payment of such maximum as allowed by law, and payment received from Borrower in excess of such legal maximum, whenever received, shall be applied to reduce the principal balance of this Note to the extent of such excess.

3. Voluntary prepayments of the principal balance of this Note shall be permitted at any time. Also, a prepayment may be deemed to have occurred regardless of whether such payment or other reduction (i) is voluntary or involuntary; (ii) is occasioned by Lender’s acceleration of the obligations hereunder or a demand hereunder; (iii) is made by Borrower or other third party, including a guarantor of Borrower’s obligation hereunder; (iv) results from Lender’s receipt or collection of proceeds of its collateral, including insurance proceeds and condemnation awards; (v) results from Lender’s exercise of its rights of setoff; and/or (iv) is made during an insolvency proceeding, or is made pursuant to any plan of reorganization or liquidation. Any such voluntary or involuntary prepayment shall be accompanied by all interest and any Administrative Fees that have accrued and remain unpaid with respect to the amount of principal being repaid and a prepayment fee equal to the following:

(a) ———-N/A———- percent (———-N/A———-%) of the amount prepaid with respect to any prepayments made during the first 12 months of the term of this Note; and

(b) ———-N/A———- percent (———-N/A———-%) of the amount prepaid with respect to any prepayments made thereafter.

Amounts repaid or prepaid with respect to this Note may not be reborrowed. Partial prepayments of principal shall be applied to scheduled payments of principal in the inverse order of their maturity.

4. If any installment of principal, interest, or Administrative Fee hereunder is not paid when due, the holder shall have the following rights in addition to the rights set forth herein, in the Loan Agreement, and under law:

(a) the right to compound interest and the Administrative Fee by adding the unpaid interest and/or Administrative Fee to principal, with such amount thereafter bearing interest and the Administrative Fee at the rates provided in this Note; and

(b) if any installment is more than ten (10) days past due, the right to collect a charge equal to the greater of Fifteen and 00/100 Dollars ($15.00) or five percent (5.00%) of the late payment for each month in which it is late. This charge is a result of a reasonable endeavor by Borrower and the holder to estimate the holder’s added legal and other costs and damages resulting from Borrower’s failure to make timely payments under this Note; hence Borrower agrees that the charge shall be presumed to be the amount of damage sustained by the holder since it is extremely difficult to determine the actual amount necessary to reimburse the holder for damages.

5. Borrower expressly waives presentment, demand, protest, notice of dishonor, notice of non-payment, notice of maturity, notice of protest, presentment for the purpose of accelerating maturity, diligence in collection, the benefit of any exemption under the homestead exemption laws, and all other notices and demands in connection with the delivery, acceptance, performance, or enforcement of this Note. Borrower agrees that Lender may release, surrender, exchange, or substitute any collateral now held or which may hereafter be held as security for the payment of this Note, and may extend the time for payment or otherwise modify the terms of payment of any part or the whole of the debt evidenced hereby. Borrower irrevocably waives the right to direct the application of all payments at any time hereafter received by Lender on behalf of Borrower, and Borrower agrees that Lender shall have the continuing exclusive right to apply any such payments against the then due and owing obligations of Borrower to Lender as Lender may deem advisable.

6. It is expressly agreed that if a default or breach occurs in the payment of any principal or interest, or other fee as provided above, or in the payment or performance of any other of Borrower’s Obligations (as that term is defined in the Loan Agreement), at Lender’s option, the unpaid principal balance of this Note, together with interest accrued thereon, and other fees as provided above shall forthwith be due and payable. Notwithstanding anything to the contrary in this Note, in the event the Revolving Line is due, owing and payable, all amounts due under this Note shall also be due, owing, and payable.

7. This Note is made subject to the terms and conditions of and is secured by security interests granted by Borrower in favor of Lender, and all covenants, conditions, and agreements contained in the Loan Agreement, and ———-N/A———-——-, all of which are hereby incorporated and made a part hereof. All capitalized terms used herein, unless otherwise defined herein, shall have the meanings ascribed to them in the Loan Agreement.

8. Borrower hereby consents to any and all renewals, replacements, and/or extensions of time for payment of this Note before, at, or after maturity. This Note shall be binding upon all legal representatives, successors, and assigns of Borrower. However, Borrower may not assign this Note or any rights hereunder without Lender’s prior written consent. Neither an unconsented assignment nor an assignment consented to by Lender shall release Borrower or any guarantor of any Obligation or indebtedness hereunder. Lender reserves the right to sell, assign, transfer, negotiate, or grant participations in all or any part of, or any interest in, Lender’s rights and benefits under each of the documents executed herewith or hereafter. In connection therewith, Lender may disclose all documents and information which Lender now has or may hereafter acquire relating to any credit extended by Lender to Borrower, or about Borrower or its business, any guarantor or the business of any guarantor, or any Collateral required hereunder. Any waiver of any rights under this Note, the Loan Agreement, or under any other agreement, instrument, or paper signed by Borrower is neither valid nor effective unless made in writing and signed by Lender. No delay or omission on the part of the Lender in exercising any right shall operate as a waiver thereof or of any other right.

9. Borrower promises to pay all legal and other costs and expenses of collection of this Note and to pay all reasonable attorneys’ fees incurred in such collection or in any suit or action to collect this Note or any appeal thereof. Borrower and Lender agree that this Note is entered into and Borrower’s performance to Lender occurs at San Jose, California. This Note shall be governed by, construed under, and enforced in accordance with the laws of the State of California.

10. Any collateral pledged to secure any obligation of Borrower shall also secure any other obligation of Borrower except that any real property pledged to secure any obligation of Borrower shall only secure any other obligation of Borrower if Lender specifically so agrees in writing.

11. An Event of Default under this Note or the Loan Agreement, or any other agreement referenced in Section 7 above shall be an Event of Default under each of such loan documents, and vice versa.

12. In the event any one or more of the provisions contained in this Note is held to be invalid, illegal or unenforceable in any respect, then such provision shall be ineffective only to the extent of such prohibition or invalidity, and the validity, legality, and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.
