SECTION 1

Description of Securities

The Companies propose to offer and sell to qualified investors up to 4,000,000 units of SRKP’s securities (the “Units”) at a price of $1.00 per Unit.

The offering will be conducted on a best-efforts basis with a minimum offering of $2,000,000, and a maximum offering of $4,000,000.  The Companies may accept subscriptions for an additional $800,000 if the Offering is oversubscribed.

SECTION 3

Issue, Sale and Delivery of the Units

3.01.

Placement Agents’ Appointment.  The Companies hereby appoint the Placement Agents as their exclusive agents to solicit purchasers for 2,000,000 Units (“Escrow Units”) on a "best efforts, all-or-none" basis, and to solicit purchasers for an additional 2,000,000 Units on a "best efforts" basis.  The Offering will terminate if the following have not occurred by September 1, 2011 (the “Escrow Date”), which date may be extended by the Companies and the Placement Agents to October 15, 2011:  (a) at least the Escrow Units are not sold; (b) the Licenses described in Section 3.03 have not been acquired; and (c) the Exchange described in 3.04 has not been consummated)(the acquisition of the Licenses and the completion of the Exchange are hereafter sometimes referred to as the “Additional Conditions”).  If the Escrow Units are sold by the Escrow Date and the Additional Conditions fulfilled by the Escrow Date, the Offering will continue until all of the Units are sold or until the Offering is terminated by the Companies and the Placement Agents.  The Placement Agents, on the basis of the representations and warranties herein contained, but subject to the terms and conditions herein set forth, accept such appointment and agree to use their best efforts to find purchasers for the Units at the Unit price of $1.00, provided that the Companies reserve the right to reject in good faith any prospective investor ("Investor") and no commission shall be payable to the Placement Agents in respect of any proposed sale to any rejected Investor.  No other person will be or has been authorized to solicit purchasers for the Units, except those persons selected by the Placement Agents.  Each Investor must subscribe for at least 25,000 Units and must certify to the Companies that such investor is an "Accredited Investor" as defined in Rule 501(a) of Regulation D.  Notwithstanding the above, the Companies and the Placement Agents may mutually agree to accept a subscription for less than $25,000.  

3.02.

Escrow Account.  It is hereby agreed between the Companies and the Placement Agents that unless 2,000,000 Units (“Escrow Units”) are sold and paid for by Investors and/or the Additional Conditions have not been fulfilled by the Escrow Date, this Agreement shall automatically be terminated and the entire proceeds received from the sale of the Units shall be returned to the Investors, without deduction therefrom or interest thereon.  During the period of the offering, the proceeds from the sale of all of the Units shall be promptly deposited in an escrow account ("Escrow Account") entitled “Arrogene NanoTechnology, Inc. Escrow Account" with Steele Street Bank and Trust, Denver, Colorado (the "Escrow Agent").  The agreement establishing the Escrow Account ("Escrow Agreement") shall be in form and content satisfactory to counsel for the Placement Agents and the Companies.  The proceeds from any sale of Units after the Initial Closing (hereinafter defined) shall continue to be deposited to the Escrow Account.  If the Escrow Units are sold by the Escrow Date, funds will be released in accordance with paragraph 3.06 until a total of 4,000,000 Units (or 4,800,000 Units if it is over-subscribed) are sold.  

3.03.

Licenses from Cedar Sinai.  Arrogene has an option to license certain technologies and patents from Cedar Sinai Medical Center (the “Licenses”).  The exercise of that option and the acquisition of the Licenses is a condition of closing of the Offering.

3.04.

The Exchange.  The Companies intend to enter into an Agreement and Plan of Reorganization pursuant to which the shareholders of Arrogene will become shareholders of SRKP (the “Exchange”).   The closing of the Minimum Offering will be contingent on the closing of the Exchange and the Exchange will be continent on the closing of Minimum Offering so that there will be simultaneous, or near-simultaneous, closings of the Minimum Offering and the Exchange.  Arrogene and SRKP will sometimes be referred to herein as the “Reorganized Company.” 

  

3.05.

Subscription Agreement.  Each Investor desiring to purchase Units will be required to complete and execute a Subscription Agreement and, if applicable, other offering documents.  The Placement Agents shall have the right to review such documents for each Investor and to reject the tender 

Arrogene NanoTechnology, Inc.

July 18, 2011

Page 5

of any Investor that it deems not acceptable.  All documents concerning any Investor the Placement Agents have not rejected will be promptly forwarded to Arrogene at the address set forth below.  Arrogene, upon receipt of the documents, will determine within three (3) business days whether it, on its own behalf and on behalf of SRKP wishes to accept the Investor.  Payment for the Units subscribed for in the Subscription Agreements that have been accepted by Arrogene is to be delivered to the Companies on the Closing Date (as hereinafter defined).

3.06.

Subscription Acceptance.  The acceptance of subscriptions for Units tendered by Investors will be conditional upon (i) the tendering of Subscriptions for at least 2,000,000 Units ("Minimum Subscriptions") by the Escrow Date; (ii) the receipt, on the Closing Date, of the net proceeds from subscribers for the Minimum Subscriptions ($2,000,000)("Minimum Payments") less commissions due the Placement Agents as provided hereinafter; (iii) the fulfillment of the Additional Conditions.  If    subscriptions are received for more than $4,000,000, the Companies may accept up to an additional $800,000, and/or it may, in its own discretion, accept one subscription over another and/or allocate available Units among subscribers as it deems appropriate.  

3.07.

Compensation of Placement Agents.  In consideration for the Placement Agents' execution of this Agreement, and for the performance of their obligations hereunder, the Companies agree to pay the Placement Agents a commission of ten percent (10%) of the gross proceeds received from the sale of the Units; provided that in the conditions specified in paragraph 3.06 are not satisfied and the Offering is terminated, the Placement Agents shall not receive any commission.  For any Investor that is referred to the Placement Agents by an officer or director of Arrogene, the commission will be reduced to 5%.  Any commissions payable to the Placement Agents under this paragraph shall be payable on the Closing Date or as otherwise provided herein.  

3.08.

Payment.  Payment for Units sold shall be made by the Escrow Agent to the Reorganized Company at such place as may be agreed on among the Companies and the Placement Agents, at such a time and on such a date, as shall be fixed by agreement between the parties, which in no case shall be, with respect to the Escrow Units, any later than eight (8) days after the Exchange Date.  The delivery of the Units against payment therefore is defined as the "Closing" and the time and date thereof are defined as the "Closing Date."  The Initial Closing Date will be held when the Minimum Payments are received and deemed cleared by the Escrow Agent ("Initial Closing") and the Additional Conditions have been satisfied.  It is anticipated that there may be additional Closings as additional funds are received, and the final Closing will be referred to as the "Final Closing."  The Final Closing could also be the Initial Closing in the event that no Units are sold after the Initial Closing.  As soon as practicable after each Closing Date, the Reorganized Company shall deliver by mail to each Investor a certificate for the securities underlying the Units that have been purchased and which contains a legend conforming to the requirements of Rule 502(d)(3) under the Securities Act.

3.09.

Obligations of Placement Agents.  The Companies agree that the obligations of the Placement Agents under this Agreement: (i) shall not preclude the Placement Agents from contemporaneously participating in the offering or underwriting of securities of other issuers; (ii) shall not impose any obligation on the Placement Agents to require their registered representatives to offer or to sell the Units, (iii) shall require the Placement Agents to make an effort to find purchasers for the Units only to the extent the Placement Agents are motivated to do so by the compensation and other provisions of this Agreement, (iv) shall not otherwise limit or prevent the Placement Agents from carrying on their customary businesses as securities broker-dealers, and (v)shall not require the Placement Agents to engage in any conduct which violates any law or industry standard of conduct applicable to the Placement Agents.

3.13.

Future Investment Banking Roles.  (a)   The Company agrees that if, at any time within 12 months following the closing of the Exchange, the Company determines to raise additional capital by means of a public offering or private placement of equity, debt or convertible securities, the Placement Agents shall have the right to act as the lead underwriters or placement agents with respect to such financing. Any decision by the Placement Agents to act in such capacity will be documented in a separate agreement or amendment hereto, which would include, among other things, customary fees, indemnification of the Placement Agents, the terms of any such financing, conditions precedent including due diligence, and current conditions, as well as customary representations and warranties.

(b)  

During the term of this Agreement or at any time within 12 months following the Closing of the Exchange, if the Company or any of its affiliates proposes (i) to dispose of an interest in any material assets or businesses (including sale or merger of the Company), or (ii) to acquire or purchase any material interest or investment in any other company or business, the Placement Agents shall have the right, at their option, to act as exclusive financial advisor with respect to such transaction.

7.01.

Indemnification by Company.  The Company agrees to indemnify, defend and hold harmless the Placement Agents, their agents, managers, members, representatives, guarantors, sureties and each person who controls the Placement Agents within the meaning of either Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) ("Indemnified Persons") from and against any and all losses, claims, damages, liabilities or expenses, joint or several, (including reasonable legal or other expenses incurred by each such person in connection with defending or investigating any such claims or liabilities, whether or not resulting in any liability to such Indemnified Persons) which they or any of them may incur under the Securities Act the Rules and Regulations, any state securities law, or any rules and regulations under any state securities laws or any other statute or at common law or otherwise and to reimburse such Indemnified Persons for any legal or other expense (including the cost of any investigation and preparation) incurred by any of them in connection with any litigation, whether or not resulting in any liability, but only insofar as such losses, claims, damages, liabilities and expenses arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Memorandum or any amendment or supplement thereto or any authorized sales literature or any application or other document filed with the Commission or any state or other jurisdiction in order to qualify the Units under the securities laws thereof, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to 

Arrogene NanoTechnology, Inc.

July 18, 2011

Page 10

make the statements therein not misleading, all as of the date of the Memorandum or such amendment or supplement, as the case may be; provided, however, that the indemnity agreement contained in this Section 7.01 shall not apply to amounts paid in settlement of any such litigation if such settlements are effected without the consent of the Company, nor shall it apply to any Indemnified Persons in respect of any such losses, claims, damages, liabilities or actions arising out of or based upon any such untrue statement or alleged untrue statement, or any such omission or alleged omission, if such statement or omission was made in reliance upon information furnished in writing to the Company by such Indemnified Persons specifically for use in connection with the preparation of the Memorandum or any such amendment or supplement thereto.  This indemnity agreement is in addition to any other liability that the Company may otherwise have to the Indemnified Persons.

7.02.

Notification to Company.  The Indemnified Persons agree to notify the Company promptly of the commencement of any litigation or proceeding against the Indemnified Persons, of which it may be advised, in connection with the offer and sale of any of the Units of the Company, and to furnish to the Company at its request copies of all pleadings therein and permit the Company to be an observer therein and apprise it of all the developments therein.  In case of commencement of any action in which indemnity may be sought from the Company on account of the indemnity agreement contained in Section 7.01, the Indemnified Persons within ten (10) days after the receipt of written notice of the commencement of any action against the Indemnified Persons, shall notify the Company in writing of the commencement thereof.  The failure to notify the indemnifying party shall not relieve it of any liability that it may have to an Indemnified Party, except to the extent that the indemnifying party did not otherwise have knowledge of the commencement of the action and the indemnifying party’s ability to defend against the action was prejudiced by such failure.  Such failure shall not relieve the indemnifying party from any other liability that it may have to the Indemnified Party.  In case any such action shall be brought against the Indemnified Persons of which the Indemnified Persons shall have notified the Company of the commencement thereof, the Company shall be entitled to participate in (and to the extent that it shall wish, to direct) the defense thereto at its own expense, but such defense shall be conducted by counsel of recognized standing and reasonably satisfactory to the Indemnified Persons in such litigation.  After notice that the Company elects to direct the defense, the Company will not be liable for any legal or other expenses incurred by the Indemnified Persons without the prior written consent of the Company.  The Company shall not be liable for amounts paid in settlement of any litigation if such settlement was effected without its consent.

7.03.

Indemnification by Placement Agents.  The Placement Agents agree to indemnify and hold harmless the Company, its agents, officers, directors, representatives, guarantors, sureties and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities or expenses, joint or several, (including reasonable legal or other expenses incurred by each such person in connection with defending or investigating any such claims or liabilities, whether or not resulting in any liability to such person) which they or any of them may incur under the Securities Act, any Rules or Regulations, any state securities law or the rules and regulations under any state securities laws or any other statute or at common law or otherwise and to reimburse persons indemnified as above for any legal or other expense (including the cost of any investigation and preparation) incurred by any of them in connection with any litigation, whether or not resulting in any liability, but only insofar as such losses, claims, damages, liabilities and litigation arise out of or are based upon any statement in or omission from the Memorandum or any amendment or supplement thereto, or any application or other document filed with the Commission or in any state or other jurisdiction in order to qualify the Units under the securities laws thereof, or any information furnished pursuant to Section 3.10 hereof, if such statements or omissions were made in reliance upon information furnished in writing to the Company by the Placement Agents or on its behalf specifically for use in connection with the preparation of the Memorandum or amendment or supplement thereto or application or document filed.  This indemnity

agreement is in addition to any other liability which the Placement Agents may otherwise have to the Company and other Indemnified Persons.

7.04.

Notification to Placement Agents.  The Company and other Indemnified Persons agree to notify the Placement Agents promptly of commencement of any litigation or proceedings against the Placement Agents or other Indemnified Persons, in connection with the offer and sale of any of the Units and to furnish to the Placement Agents, at their request, copies of all pleadings therein and permit the Placement Agents to be an observer therein and apprise the Placement Agents of all developments therein, all at the Company's expense.  In case of commencement of any action in which indemnity may be sought from the Placement Agents on account of the indemnity agreement contained in Section 7.03, the Company or other Indemnified Persons shall notify the Placement Agents of the commencement thereof in writing within ten (10) days after the receipt of written notice of the commencement of any action against the Company or against any other person indemnified.  The failure to notify the indemnifying party shall not relieve it of any liability that it may have to an Indemnified Party, except to the extent that the indemnifying party did not otherwise have knowledge of the commencement of the action and the indemnifying party’s ability to defend against the action was prejudiced by such failure.  Such failure shall not relieve the indemnifying party from any other liability that it may have to the Indemnified Party.  In case any such action shall be brought against the Company or any other person indemnified of which the Company shall have notified the Placement Agents of the commencement thereof, the Placement Agents shall be entitled to participate in (and to the extent that it shall wish, to direct) the defense thereto at its own expense, but such defense shall be conducted by counsel of recognized standing and reasonably satisfactory to the Company or other persons indemnified in such litigation.  After notice that the Placement Agents elects to direct the defense, the Placement Agents will not be liable for any legal or other expenses incurred by the indemnified party without the prior written consent of the Placement Agents.  The Placement Agents shall not be liable for amounts paid in settlement of any litigation if such settlement was effected without their consent.

7.05.

Indemnification of Selected Dealers.  The Company agrees to indemnify Selected Dealers, if any, and their agents, officers, directors, representatives, guarantors and sureties on substantially the same terms and conditions as it indemnifies the Placement Agents and Indemnified Persons pursuant to Section 7.01 provided that each such Selected Dealer will have agreed in writing with the Placement Agents to indemnify the Company and its agents, officers, directors, representatives, guarantors and sureties on substantially the same terms and conditions as the Placement Agents indemnifies the Company in Section 7.03.  The Company hereby authorizes the Placement Agents to enter into agreements with Selected Dealers providing for such indemnity by the Company.

7.06.

Contribution.  If the indemnification provided for in Sections 7.01, 7.03 and 7.05 is unavailable to an indemnified party in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under either such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities:  (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Placement Agents or Selected Dealers on the other from the offering and sale of the Units, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Placement Agents or Selected Dealers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Placement Agents or Selected Dealers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bears to the total commissions received by the Placement Agents or Selected Dealers, as in each case set forth in the 

Arrogene NanoTechnology, Inc.

July 18, 2011

Page 12

Memorandum.  The relative fault of the Company and of the Placement Agents or Selected Dealers shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or by the Placement Agents or Selected Dealers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Placement Agents agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph.  The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 7, the Placement Agents shall not be required to contribute any amount in excess of the amount by which the total price at which the Units sold by it and distributed exceeds the amount of any damages which such Placement Agents otherwise has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution hereunder from any person who was not guilty of such fraudulent misrepresentation.

7.07.

Limitation of Legal Expenses.  Notwithstanding anything herein to the contrary, the indemnification for legal expenses included in Sections 7.01, 7.03,  and 7.05 shall be limited to the legal expenses of one law firm, except in the event of a bona fide conflict of interest, in which event such legal expenses shall be limited to the legal expenses of two law firms.

ESCROW AGREEMENT

This Escrow Agreement (this “Agreement”) is entered into as of July 18, 2011, by and among SRKP 16, Inc., a Delaware corporation (“SRKP”), Arrogene NanoTechnology, Inc. (“Arrogene”) (SRKP and Arrogene are sometimes referred to herein as the “Companies”), GVC Capital LLC, a Colorado limited liability company, and WestPark Capital, Inc., a California corporation (“Placement Agents”), and Steele Street Bank & Trust (in its capacity as escrow holder, the “Escrow Agent”).

RECITALS

This Agreement is entered into in reference to the following facts:

A.

The Companies intend to offer for sale up to 4,800,000 Units of SRKP’s securities (the “Units”) at $1.00 per Unit, in a private placement pursuant to Rule 506 of Regulation D, promulgated under the Securities Act of 1933, as amended, including the over-allotment option described below (the “Offering”).  The sales shall be made through the Placement Agents only to Accredited Investors, as that term is defined in Rule 501(a) of Regulation D (the “Investors”), on a best efforts basis for a minimum offering of 2,000,000 Units (the “Minimum Offering”) or $2,000,000 (the “Minimum Amount”) and a maximum offering of 4,000,000 Units or $4,000,000 (the “Maximum Offering”) with a 800,000 Unit over-allotment option (an additional $800,000).  

B.

Arrogene has an option to license certain technologies and patents from Cedar Sinai Medical Center (the “Licenses”).  The exercise of that option and the acquisition of the Licenses is a condition of closing of this Offering.

C.

The Companies intend to enter into an Agreement and Plan of Merger and Reorganization (the “Exchange”).  A condition of closing of the Exchange is the sale of at least the Minimum Offering.  The Closing of the Minimum will be contingent on the closing of the Exchange.      

D.

The Companies and the Placement Agents desire that the Escrow Agent act as escrow holder for the funds from the Investors for the Units (the “Offering Proceeds”) received by the Companies or the Placement Agents until (a) (i) the proceeds from the Maximum Offering, (including the over-allotment option) and written request for closing from the Placement Agents and the Companies have been received by the Escrow Agent; (ii) the Closing of the Exchange; and (iii) the Licenses have been acquired; or (b) the Escrow Termination Date (defined below), whichever shall first occur.  

C.

The Escrow Agent is willing to act in such capacity, subject to the terms and conditions hereof.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto hereby agree as follows.

ARTICLE 1 – ESCROW FUNDS

1.1

1.2

Escrow Account.  Immediately following the Escrow Agent’s execution of this Agreement and prior to the date of the commencement of the Offering, the parties shall establish an account at Steele Street Bank & Trust (the "Escrow Account”) for the sole purpose of receiving, holding and disbursing the Offering Proceeds in accordance with the terms hereof.  The account shall be a demand deposit account, and deposits in such Escrow Account will not bear interest and will not otherwise be invested by the Escrow Agent on behalf of the Companies or the Investors.

(b)

The Offering Proceeds in the form of wires are deemed deposited into the Escrow Account when delivered to the Escrow Agent.  Any Offering Proceeds deposited in the form of a check, draft or similar instrument are deemed deposited only when such item is collected by the Escrow Agent (hereinafter, “Collected Funds”).  All such checks and similar instruments shall be made payable to “Arrogene NanoTechnology, Inc. Escrow Account.”  Any checks or other instruments that are not made so payable shall be returned by the Escrow Agent to the party submitting the check or other similar instrument.  Any check returned unpaid to the Escrow Agent shall be returned to the party that submitted the check, and the Escrow Agent shall promptly notify the Companies and Placement Agents of such return.

(c)

The Offering Proceeds shall be disbursed by the Escrow Agent from the Escrow Account by wire transfer of funds or by check payable to the appropriate distributee in accordance with instructions provided at the time of the Closing by a writing signed by Arrogene, SRKP, GVC, and WestPark, with respect to the Companies and the Placement Agent, and in accordance with the information provided to the Escrow Agent pursuant to Section 1.3(a), with respect to each Investor.

Subject to the foregoing, the amount of Collected Funds to be disbursed shall be determined by the Companies and the Placement Agents.  After the Initial Closing, there may be one or more additional closings until the Maximum Offering and over-allotment option amount has been dispersed.  The Companies shall determine, in their sole discretion, which investor’s funds will be in such disbursals.  The Companies and Placement Agents shall notify the Escrow Agent that they intend to conduct an additional closing of the Offering (each, an “Additional Closing”), and at least one (1) business day thereafter, at the written request of the Companies and the Placement Agents, any funds that have been held in the Escrow Account but not disbursed (but not more than a total of $4,800,000) may be disbursed (the “Final Closing”).

The Companies represents, warrants and agrees that the Offering Proceeds returned to each such Investor are and shall be free and clear of any and all claims of the Companies and its creditors.

 (ii)

Promptly after its receipt of such notice, the Escrow Agent shall return to the subject Investor, as a complete distribution, his subscription amount.  If the Companies or Placement Agents rejects any subscription for which the Escrow Agent has not yet received Collected Funds, but has submitted the Investor’s check for collection, then the Escrow Agent shall promptly issue a check in the amount of the Investor’s check to the rejected Investor after the Escrow Agent has cleared such funds.  If the Escrow Agent has not yet submitted a rejected Investor’s check for collection or the Investor’s check is returned uncollected, then the Escrow Agent shall promptly remit the Investor’s check directly to the Investor.

(e)

The Escrow Agent shall not be required to take any action under this Section 2.1 until it shall have received proper written notification from the Companies or the Placement Agents when required under this Agreement.

Upon final disbursement of the Offering Proceeds, the Escrow Agent shall deliver to the Companies and Placement Agents a complete accounting of all transactions relating to the Offering Proceeds.

3.2

Duties.  The Escrow Agent’s duties and obligations hereunder shall be determined solely by the express provisions of this Agreement.  The Escrow Agent’s duties and obligations are purely ministerial in nature, and nothing in this Agreement shall be construed to give rise to any fiduciary obligations of the Escrow Agent with respect to the Investors or to the other parties to this Agreement.  The Escrow Agent is not charged with any duties or responsibilities with respect to the Offering Memorandum or any related document and shall not otherwise have a duty to be concerned with the terms thereof.  For purposes of communications and directives, the Escrow Agent shall only accept instructions from the Companies or the Placement Agents as may be required by this Agreement.  The Escrow Agent shall not be required to notify or obtain the consent, approval, authorization or order of any court or governmental body or of any Investor or any other person to perform its obligations under this Agreement.

3.3

Disputes.  If there is any disagreement or the presentation of any adverse claim or demand in connection with the disbursement of the Offering Proceeds, the Escrow Agent, at its option, after providing written notice to the Companies and the Placement Agents of such disagreement or adverse claim or demand, may refuse to comply with any such claims or demands during the continuance of such disagreement and may refrain from delivering any item affected hereby, and in so doing, the Escrow Agent shall not become liable to the undersigned or to any other person, due to its failure to comply with such adverse claim or demand.  If the Companies and Placement Agents do not provide satisfactory assurances to the Escrow Agent that it may act in accordance with the other provisions of this Agreement, then the Escrow Agent shall be entitled to continue, without liability, to refrain and refuse to act until:

(a)

authorized to disburse the Offering Proceeds by an order from a court purporting to have jurisdiction over the parties and the Offering Proceeds, after which time the Escrow Agent shall be entitled to act in conformity with such order; or

4

(b)

the Escrow Agent (i) shall have been notified that all differences shall have been adjusted by agreement, and (ii) shall have been directed in writing to take certain actions with respect to the Offering Proceeds subject to the adverse claim or demand, signed jointly or in counterpart by the Companies, the Placement Agents and by all persons making adverse claims or demands, at which time the Escrow Agent shall be protected in acting in compliance therewith.

At any time prior to the Escrow Agent’s receipt of a court order or a notice, as provided in Section 3.3(a) or Section 3.3(b), the Escrow Agent may, but is not required to, file a suit in interpleader and deposit the Offering Proceeds with the District Court and obtain an order from the court requiring the parties to interplead and litigate in such court adverse claims or demands raised pursuant to this Section 3.3.  If such interpleader suit is brought, the Escrow Agent shall ipso facto be fully released and discharged from all obligations to further perform any and all duties or obligations imposed upon it in relation to the disputed amount.  The Companies and Placement Agents agree to reimburse the Escrow Agent for all costs, expenses and reasonable attorney’s fees expended or incurred by the Escrow Agent in connection with such adverse claim or demand, the amount thereof to be fixed and judgment thereof to be rendered by the court in such lawsuit.  In addition and without the institution of legal proceedings, the Escrow Agent shall have the right to consult with attorneys or other advisors of its choosing concerning its rights, duties or obligations hereunder, and the Companies and Placement Agents shall pay or reimburse the Escrow Agent for all costs, fees and expenses thereby incurred.

3.4

Liability Limited.  The Escrow Agent shall not be liable to anyone whatsoever by any reason of error of judgment or for any act done or step taken or omitted by it in good faith or for any mistake of fact or law or for anything which it may do or refrain from doing in connection herewith unless caused by or arising out of its own gross negligence or willful misconduct.  In no event shall the Escrow Agent be liable for any indirect, special, consequential or punitive damages.  The Companies and Placement Agents represent to the Escrow Agent that they have and shall continue to solicit the advice of their respective counsel regarding compliance with all applicable state and federal securities laws in connection with the offer and sale of the Units, and that they will act in accordance with such laws.  The Escrow Agent shall have no responsibility to ensure the Companies’ or Placement Agents’ compliance with any such securities laws in connection with the Offering.  

3.5

Reliance on Documents, Etc.  The Escrow Agent may rely on and shall be protected in acting in reliance upon any instructions or directions furnished to it in writing or pursuant to any provisions of this Agreement and shall be entitled to treat as genuine, and as the document it purports to be, any letter, paper or other document furnished to it and believed by it to be genuine and to have been signed and presented by the proper party or parties.  The Companies and Placement Agents shall not include the Escrow Agent’s name in any document unless such document has been approved in writing by the Escrow Agent, except with regard to those documents pertaining to and referring to the Escrow Agent’s functions as escrow holder pursuant to this Agreement.

3.6

Indemnification.  The Companies and Placement Agents, jointly and severally, agree to indemnify, defend and hold harmless the Escrow Agent from and against all losses, damages, costs, charges, payments, liabilities and expenses, including all costs of litigation, investigation and reasonable legal fees incurred by the Escrow Agent and arising directly or indirectly out of its role as Escrow Agent pursuant to this Agreement, except as caused by its willful misconduct or gross negligence.  The Companies and Placement Agents hereby agree that the Escrow Agent does not assume any responsibility for the failure of any other of the parties to make payments or perform the conditions of this Agreement as set forth herein.  The Escrow Agent may consult with counsel of its choice and shall have full and complete authorization and protection for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel.  The provisions of this Section 3.6 shall survive the termination of this Agreement.

3.7

Resignation.  The Escrow Agent may resign as the escrow holder at any time by giving thirty (30) days prior written notice thereof to all other parties.  Upon notice of resignation by the Escrow Agent, the other parties shall appoint a replacement escrow holder within that thirty (30) day period.  The Escrow Agent may deliver the Offering Proceeds to the replacement escrow holder upon (a) notice of the appointment of a new escrow holder, and (b) payment to the Escrow Agent in full of all fees then due and payable to the Escrow Agent.  If no such replacement or substitute has been appointed within 30 days of the Escrow Agent’s notice of resignation, then the Escrow Agent, at the expense of the Companies and Placement Agents, may petition any court of competent jurisdiction for the appointment of a successor escrow holder.  Upon appointment of successor escrow holder, the Escrow Agent shall forward all documents and deposits pertaining to the escrow to the successor, and the Escrow Agent shall thereafter have no duties or obligations hereunder.
