Acceptance by Hirshfield Law (the "Escrow Agent") of its duties under the Escrow Agreement to which this is attached is subject to the following terms and conditions (the "Standard Terms"), which all parties to the Escrow Agreement hereby agree shall govern and control the rights, duties and privileges of the Escrow Agent and shall be deemed incorporated by reference into the Escrow Agreement as if set forth in full therein (the Escrow Agreement and these Standard Terms shall together be referred to as the "Agreement"):

The duties of the Escrow Agent are to be determined solely by the express provisions of the Agreement and the Escrow Agent shall have no responsibilities except the performance of such duties and obligations as are specifically set forth in the Agreement.

The Escrow Agent shall not be liable for any error of judgment, or for any act taken or omitted by it, or for any mistake in fact or law, or for anything which it may do or refrain from doing in connection herewith, except for its own willful misconduct. Without limiting the generality of the foregoing, the Escrow Agent shall not incur liability and shall be fully protected in respect of any action taken, omitted or suffered by it in good faith.

The Escrow Agent shall be entitled to act on or rely upon any written notice, direction, request, waiver, consent, receipt or other paper or document which appears to have been signed or presented by the party or parties entitled to execute or deliver such document, and the Escrow Agent shall have no duty to inquire of or investigate the authorization, signature or authenticity of such person or document.

The Escrow Agent shall have no duty to invest or earn interest on any funds held in escrow. It may, however, deposit such funds or proceeds thereof in or with any bank, savings or loan association, trust company, money market mutual fund or financial institution (in its own name or in the name of any of its members or nominees). The Escrow Agent has no obligation to, and does not undertake to, perfect any security interests in any of the property, register any of the property or the proceeds thereof, invest or redeem any of the property or proceeds thereof, or surrender or tender any of the property or the proceeds thereof for any reason, or in any other respect enforce the obligations or preserve the rights of any party relating to any notes, debt instruments, securities, contracts or other property or proceeds thereof held in escrow.

The Escrow Agent may resign its duties and shall thereupon be discharged from all further duties or obligations hereunder at any time upon giving 10 days' written notice to the parties to the Agreement. The parties to the Agreement will thereupon jointly designate a successor escrow agent hereunder within said 10-day period to whom the property held in escrow shall be delivered and shall deliver to the Escrow Agent a general release executed by all parties to the Agreement (other than the Escrow Agent) and shall pay the Escrow Agent in full any amounts owed to it under the Agreement. In default of such a joint designation of a successor escrow agent and delivery of such release and amounts, and unless the Escrow Agent has deposited the property held in escrow with a court, the Escrow Agent shall retain the property theretofore held in escrow as custodian thereof until otherwise directed by the parties to the Agreement jointly, without further liability or responsibility.

The parties to the Agreement other than the Escrow Agent (collectively referred to as the "Indemnitors")jointly and severally agree to indemnify the Escrow Agent and its members, employees and agents (jointly and severally the "Indemnitees") against, and hold them harmless of and from, any and all loss, liability, cost, damage and expense, including, without limitation, reasonable counsel fees (including those of the Escrow Agent computed at its regular hourly rates), which the Indemnitees may suffer or incur by reason of any action, claim or proceeding brought or threatened to be brought, whether by any party hereto or by any other person or entity, against any Indemnities or in which any Indemnities may become involved arising out of or relating directly or indirectly in any way to the Agreement or any transaction to which the Agreement directly or indirectly relates. If the indemnification provided for in this paragraph for any reason is held to be unavailable, the Indemnitors shall contribute such amounts as are, as between the Indemnitors, just and equitable to pay to the Indemnitees or to reimburse them for, the aggregate of any and all losses, liabilities, costs, damages and expenses, including counsel fees, incurred by the Indemnitees as a result of or in connection with, and any amount paid in settlement of, any action, claim or proceeding arising out of or relating directly or indirectly in any way to the Agreement or any transaction to which the Agreement directly or indirectly relates. The provisions of this paragraph shall survive any termination of the Agreement, whether by disbursement of the property held in escrow, the resignation of the Escrow Agent or otherwise.

The Escrow Agent may, but shall not be obligated to, in its sole discretion at any time and from time to time, for any reason or for no reason, commence an interpleaded or other action, suit or proceeding for the resolution of any controversy regarding this Agreement or the subject matter of its escrow.

THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS BY, AND BE CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CALIFORNIA WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICT OF LAWS, AND THIS AGREEMENT CANNOT BE CHANGED OR TERMINATED EXCEPT BY A WRITING SIGNED BY ALL OF THE PARTIES HERETO. THE PARTIES TO THIS AGREEMENT HEREBY AGREE THAT NO ACTION, SUIT OR PROCEEDING SHALL BE COMMENCED AGAINST THE ESCROW AGENT UNLESS (A) THE ESCROW AGENT SHALL FIRST HAVE BEEN GIVEN 30 DAYS' WRITTEN NOTICE OF THE CLAIM AND (B) THE SAME IS BROUGHT IN A COURT OF COMPETENT JURISDICTION LOCATED IN THE COUNTY OF SAN FRANCISCO, STATE OF CALIFORNIA. THE PARTIES TO THE AGREEMENT OTHER THAN THE ESCROW AGENT AGREE THAT IN ANY ACTION, SUIT OR OTHER PROCEEDING COMMENCED BY THE ESCROW AGENT, SERVICE BY MAIL AS PROVIDED HEREIN SHALL BE DEEMED GOOD, PROPER AND EFFECTIVE SERVICE UPON SAID PARTY, AND EACH CONSENTS TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN THE COUNTY OF SAN FRANCISCO (OR ANY OTHER COURT SELECTED BY THE ESCROW AGENT) IN ANY ACTION, SUIT OR PROCEEDING HEREUNDER, HEREBY WAIVING ANY AND ALL RIGHT TO OBJECT TO THE JURISDICTION OR VENUE OF SAID COURT.

If a controversy arises between one or more of the parties hereto, or between any of the parties hereto and any person not a party hereto, as to whether or not or to whom the Escrow Agent shall deliver the property held in escrow or any portion thereof, or as to any other matter arising out of or relating to the Agreement or the property held in escrow, the Escrow Agent shall not be required to make any inquiry or investigation, or make any determination as to such controversy, and need not make any delivery of such property but may retain it until the rights of the parties to the dispute shall have finally been determined by agreement in form, substance and formalities satisfactory to the Escrow Agent or by final order of a court of competent jurisdiction from which final order the time for appeal has expired without an appeal having been taken. If and to the extent directed to do so by said agreement or final order the Escrow Agent shall deliver the property held in escrow within a reasonable time after the Escrow Agent has received written notice of any such agreement or final order, accompanied by proof satisfactory to it of the validity of such agreement and/or the finality of such order. The Escrow Agent shall be entitled to assume that no such controversy has arisen unless it has received a written notice that such a controversy has arisen which refers specifically to the Agreement and identifies by name and address all parties to the controversy. Notwithstanding anything to the contrary set forth in the Agreement, the Escrow Agent shall be entitled to comply with any order of any court or other lawful authority which has not been stayed.

All notices, requests and other communications which may or must be given hereunder shall be in writing and shall be deemed to have been duly given when mailed by registered or certified mail, return receipt requested, to each of the parties at their addresses set forth in the Agreement. Any of the parties hereto by notice in writing delivered or mailed to the other parties hereto, as aforesaid, may change the name or address, or both, to which future notices to it shall be delivered or mailed.

This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, personal representatives, successors and permitted assigns, but not to the benefit of any third party. The Agreement and any rights thereunder may not be assigned without the prior written consent of the Escrow Agent, and any purported assignment without the Escrow Agent's prior written consent shall be null and void and of no effect whatsoever. The rights granted the Escrow Agent herein are cumulative and the exercise of any one or more rights hereunder shall not constitute a waiver of the Escrow Agent's right to assert all other legal and equitable remedies available to it under the circumstances. If one or more of the provisions or paragraphs of the Agreement shall be held to be illegal or otherwise void or invalid, the remainder of the Agreement shall not be affected and shall remain in full force and effect.

The parties to the Agreement acknowledge that the Escrow Agent has or may have represented one or more of the parties to the Agreement in the past, and consent to the continued representation by the Escrow Agent of one or more parties to the Agreement.

To the extent inconsistent with any terms or provisions of the Escrow Agreement to which this is attached, the provisions of these Standard Terms shall govern.
