In furtherance and not in limitation of the foregoing, the Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary; provided, that if the Bank shall receive prior written notification from the Borrower that sufficiently identifies, in the opinion of the Bank, documents to be presented to the Bank that are not to be honored, the Bank agrees that it will not honor such documents.

     Section 7.7 Expenses and Taxes. The Borrower will promptly pay all Expenses.

     Section 7.8 No Waiver; Conflict.

          (a) Neither any failure nor any delay on the part of the Bank in exercising any right, power or privilege hereunder, nor any course of dealing with respect to any of the same, shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

          (b) To the extent of any conflict between this Agreement on the one hand and any other Related Document on the other hand, this Agreement shall control as between the Borrower and the Bank.

     Section 7.9 Modification, Amendment, Waiver, Etc.

     Section 7.11 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction, and the remaining portion of such provision and all other remaining provisions hereof will be construed to render them enforceable to the fullest extent permitted by law.

the Bank relating to the Letter of Credit, including those contained in any commitment letter between the Bank and the Borrower executed in anticipation of this Agreement.

     Section 7.15 CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER.

          (a) THE VALIDITY OF THIS AGREEMENT AND THE OTHER RELATED DOCUMENTS (UNLESS EXPRESSLY PROVIDED TO THE CONTRARY IN ANOTHER LOAN DOCUMENT IN RESPECT OF SUCH OTHER RELATED DOCUMENT), THE CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF AND THEREOF, AND THE RIGHTS OF THE PARTIES HERETO AND THERETO WITH RESPECT TO ALL MATTERS ARISING HEREUNDER OR THEREUNDER OR RELATED HERETO OR THERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF CALIFORNIA, WITHOUT REGARD FOR PRINCIPLES OF CONFLICTS OF LAWS.

          (b) THE PARTIES AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT AND THE OTHER RELATED DOCUMENTS SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF SANTA CLARA, STATE OF CALIFORNIA, PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT BANK’S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE BANK ELECTS TO BRING SUCH ACTION OR WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. THE BORROWER AND THE BANK WAIVE, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, ANY RIGHT EACH MAY HAVE TO ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION.

          (c) THE BORROWER AND THE BANK HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE RELATED DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. THE BORROWER AND BANK REPRESENT THAT EACH HAS REVIEWED THIS WAIVER AND EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

     Section 7.16 Reference Provision.

          (a) In the event the Jury Trial Waiver provision contained in Section 7.16(c) is invalid or unenforceable, the parties elect to proceed under this Judicial Reference Provision.

          (b) Other than (i) nonjudicial foreclosure of security interests in real or personal property, (ii) the appointment of a receiver or (iii) the exercise of other provisional remedies (any of which may be initiated pursuant to applicable law), any controversy, dispute or claim (each, a "Claim”) between the parties arising out of or relating to this Agreement or any Loan Document, will be resolved by a reference proceeding in California in accordance with the provisions of Section 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided herein or in the Related Documents, venue for the reference proceeding will be in the Superior Court or Federal District Court in the County or District where the real property, if any, is located or in a County or District where venue is otherwise appropriate under applicable law (the “Court”).

          (c) The referee shall be a retired Judge or Justice selected by mutual written agreement of the parties. If the parties do not agree, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. The referee shall be appointed to sit with all the powers provided by law. Each party shall have one peremptory challenge pursuant to CCP §170.6. Pending appointment of the referee, the Court has power to issue temporary or provisional remedies.

          (d) The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested to (i) set the matter for a status and trial- setting conference within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try all issues of law or fact within ninety (90) days after the date of the conference and (iii) report a statement of decision within twenty (20) days after the matter has been submitted for decision. Any decision rendered by the referee will be final, binding and conclusive, and judgment shall be entered pursuant to CCP §644.

          (e) The referee will have power to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered, no party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding.

          (f) Except as expressly set forth in this Agreement, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to

award costs to the prevailing party, the parties will equally share the cost of the referee and the court reporter at trial.

          (g) The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, provide all temporary or provisional remedies, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a trial, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. The referee’s decision shall be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision.

          (h) If the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or Justice, in accordance with the California Arbitration Act §1280 through §1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding.

          (i) THE PARTIES RECOGNIZE AND AGREE THAT ALL DISPUTES RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY, AND THAT THEY ARE IN EFFECT WAIVING THEIR RIGHT TO TRIAL BY JURY IN AGREEING TO THIS REFERENCE PROVISION. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY AND FOR THEIR MUTUAL BENEFIT AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO ANY DISPUTE BETWEEN THEM WHICH ARISES OUT OF OR IS RELATED TO THIS AGREEMENT OR THE RELATED DOCUMENTS.
