SUBSCRIPTION AGREEMENT SPECTRAL MOLECULAR IMAGING, INC.

EXHIBIT 4.2

SPECTRAL MOLECULAR IMAGING, INC.

To:

Spectral Molecular Imaging, Inc.

This Subscription Agreement (this “Subscription Agreement”) is made by and between Spectral Molecular Imaging, Inc., a Nevada corporation (the “Company”), and the undersigned prospective purchaser (the “Investor”) who is subscribing hereby for units (“Units”). Each Unit consists of one share of the Company’s common stock, $0.001 par value (sometimes referred to herein as the “Common Stock” and sometimes, the “Shares”) and one Common Stock purchase warrant (a “Warrant”). The Investor has received that certain Offering Memorandum of the Company, dated July 5, 2005 and all exhibits and any supplements referred to therein (the “Memorandum”). Each Warrant is exercisable for one share of Common Stock at two dollars and fifty cents ($2.50) per share for a period of three years. The Units are offered and sold in multiples of 20,000 Units for $1.00 per Unit. All information contained in this Subscription Agreement is after taking into effect a pending stock split of the Common Stock described in the Memorandum. The Company may, in its discretion, sell a limited number of Units in multiples of 10,000 Units (for $10,000). The Units are offered to Accredited Investors (hereinafter defined) only. All funds received by the Company pursuant to subscriptions for the Units will be deposited in a segregated bank account established by the Company. The Company is selling certain of the Units through finders, who will receive compensation described in the Memorandum in connection with introducing purchasers of the Units to the Company.

In consideration of the Company’s agreement to sell Units to the Investor upon the terms and conditions summarized in the Memorandum, the Investor or Company, as the case may be, agrees and represents as follows:

A.	SUBSCRIPTION.

1. The Investor hereby irrevocably subscribes for and agrees to purchase the number of Units indicated on the signature page hereof at a purchase price of one dollar ($1.00) per Unit. The Investor encloses herewith a check payable to “Spectral Molecular Imaging, Inc.—Special Account” or has wire transferred to Bank of America, routing number ▇▇▇▇▇▇▇▇▇, for deposit to the Company’s account number 2151940728 in the amount of the purchase price of the Units for which the Investor is subscribing (the “Payment”). Subscription payments shall be made in U.S. funds, although the Company reserves the right to accept payment in Canadian funds at the prevailing exchange rate at the time of the subscription at its sole discretion.

2. No Units will be sold unless (a) the Company receives and accepts subscriptions for at least 1,500,000 Units on or before August 31, 2005, which date may be extended by the Company in its sole discretion to not later than September 30, 2005, and with the Offering continuing after receipt and acceptance of the subscriptions for at least 1,500,000 Units by the foregoing deadline (the “Minimum Subscription Date”) until October 31, 2005 or such earlier date as the Company in its sole discretion shall determine (the “Provisional Offering Closing”), and (b) the Company completes the Reorganization transaction with Patco Industries, Ltd., a Delaware corporation (the “Public Company”) in the manner described in the Memorandum (the “Reorganization”) within 30 days after the Provisional Offering Closing (the “Final Closing”). The date of the Provisional Offering Closing shall be that date as shall be chosen by the Company. All subscription funds for the purchase of Units

will be held in a segregated bank account of the Company (the “Escrow”) until immediately prior to the Reorganization. If subscriptions for at least 1,500,000 Units are not received and accepted by the Minimum Subscription Date or if the Final Closing does not occur within 30 days after the Provisional Offering Closing, all funds held in the Escrow will be promptly returned to investors without deduction therefrom or interest thereon. The sale of the Units will be deemed to have been completed immediately prior to the Final Closing, the Investor will become a stockholder of the Company immediately prior to the Final Closing, and the name of such purchaser will be registered on the stock transfer books of the Company immediately prior to the Final Closing as the record owner of such Shares and Warrants. Immediately following the foregoing sale of Shares and Warrants, the Shares and Warrants purchased by the Investor will be exchanged in the Reorganization for shares of the Public Company’s common stock and a warrant to purchase shares of the Public Company’s common stock, and the Public Company shall issue to each subscriber whose subscription is accepted, (i) one or more stock certificates representing the shares of the Public Company’s common stock for which the Shares were exchanged in the Reorganization, and (ii) a Warrant representing the purchaser’s right to purchase additional shares of the Public Company’s common stock. The Company may reject any subscription, in whole or in part, for any reason. The Payment (or, in the case of rejection of a portion of the Investor’s subscription, the part of the Payment relating to such rejected portion) will be returned promptly if the Investor’s subscription is rejected in whole or in part.

B.	REGISTRATION.

As part of the Reorganization, the Public Company has agreed to file within 90 days following the completion of the Reorganization a registration statement with the SEC to register all of the shares of Common Stock and all of the shares of Common Stock underlying the Warrants purchased by the Investor. The terms, conditions and limitations of the foregoing registration rights are set forth on Appendix I to this Subscription Agreement. The Investor hereby agrees to be bound by the terms and conditions set forth on Appendix I.

C.	REPRESENTATIONS AND WARRANTIES.

C.1 Representations and Warranties by All Investors.

The Investor hereby represents and warrants to, and agrees with, the Company as follows:

1. The Investor has sufficient liquid assets to sustain a loss of the Investor’s entire investment.

2. The Investor represents that he is resident in the jurisdiction set forth on the signature page to this Subscription Agreement and is an Accredited Investor as that term is defined in Regulation D (“Regulation D”) promulgated under the Securities Act of 1933, as amended (the “Act”), and summarized in the Memorandum. The Investor also represents that he, either alone or with the Investor’s representative(s), has such knowledge and experience in financial and business matters that the Investor is capable of evaluating the merits and risks of the investment in the Units.

3. The Investor represents that he: (i) has adequate means of providing for his current financial needs and possible personal contingencies, and has no need for liquidity of his investment in the Company; (ii) can afford (a) to hold unregistered securities for an indefinite period of time and (b) sustain a complete loss of the entire amount of the subscription; and (iii) has not made an overall commitment to investments which are not readily marketable that is so disproportionate as to cause such overall commitment to become excessive.

4. The Investor’s Units are being purchased for the Investor’s own account, for investment purposes only, not for the account of any other person, and not with a view to distribution, assignment or resale to others or to fractionalization in whole or in part. No other person has or will have a direct or indirect beneficial interest in the Investor’s Units. The Investor will not sell, hypothecate or otherwise transfer the Investor’s Units unless: (a) there is an effective registration statement under the Act and applicable state securities laws covering any transaction involving such securities, or (b) an exemption from the registration requirements of the Act and such state laws is available.

5. The Investor has been furnished with and has carefully read the Memorandum and is familiar with and understands the terms of the offering. In evaluating the suitability of an investment in the Company, the Investor has not relied upon any representations or other information (whether oral or written) from the Company, other than as set forth in the Memorandum. With respect to the Investor’s tax and other economic considerations involved in this investment, the Investor is not relying on the Company. The Investor has carefully considered and has, to the extent the Investor believes such discussion necessary, discussed with the Investor’s professional legal, tax, accounting and financial advisors the suitability of an investment in the Units for the Investor’s particular tax and financial situation and has determined that the Units being subscribed for by the Investor are a suitable investment for the Investor.

6. The Company has made available to the Investor all documents and information that the Investor has requested relating to an investment in the Units.

7. The Investor has received, read, understands and is familiar with the Memorandum, including, without limitation, the “Risk Factors” section contained therein and the exhibits attached thereto.

8. The Investor confirms that the Company has made available to the Investor the opportunity to ask questions of, and receive answers from, representatives of the Company concerning the Offering, the Company and the activities of the Company, the Public Company, and otherwise to obtain any additional information, to the extent that the Company possesses such information or could acquire it without unreasonable effort or expense, necessary to verify the accuracy of the information contained in the Memorandum, and the Investor does not require any additional information concerning the foregoing.

9. The Investor recognizes that the Company is an early development stage company that has not generated any revenues to date and is not expected to have any products commercially available for a number of years, if at all. In addition, the Public Company has not conducted any business operations in recent years. Therefore, the Investor realizes that an investment in the Company involves substantial risks, including loss of the entire amount of such investment, and has taken full cognizance of and understands all of the risk factors relating to the purchase of the Units.

10. If this Subscription Agreement is executed and delivered on behalf of a partnership, corporation, trust or estate: (i) such partnership, corporation, trust or estate has the full legal right and power and all authority and approval required: (a) to execute and deliver, or authorize execution and delivery of, this Subscription Agreement and all other instruments executed and delivered by or on behalf of such partnership, corporation, trust or estate in connection with the purchase of its Units, (b) to delegate authority pursuant to a power of attorney, and (c) to purchase and hold such Units; (ii) the signature of the party signing on behalf of such partnership, corporation, trust or estate is binding upon such partnership, corporation, trust or estate, and (iii) such partnership, corporation or trust has not been formed for the specific purpose of acquiring such Units, unless each beneficial owner of such

entity is qualified as an Accredited Investor within the meaning of Rule 501 (a) of Regulation D, and has submitted information substantiating such individual qualification.

11. The Investor shall indemnify and hold harmless the Company, and each officer, director or control person of any such entity, who is or may be a party or is or may be threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of or arising from any actual or alleged misrepresentation or misstatement of facts or omission to represent or state facts made or alleged to have been made by the Investor to the Company or omitted or alleged to have been omitted by the Investor, concerning the Investor or the Investor’s authority to invest or financial position in connection with the offering or sale of the Units, including, without limitation, any such misrepresentation, misstatement or omission contained in the Questionnaire submitted by the Investor, against losses, liabilities and expenses for which the Company or any officer, director or control person of any such entity has not otherwise been reimbursed (including, without limitation, attorneys’ fees, judgments, fines and amounts paid in settlement) actually and reasonably incurred by the Company or such officer, director or control person in connection with such action, suit or proceeding.

C.2 Additional Representations and Warranties by Canadian Residents.

1. The Investor, if resident in either British Columbia or Alberta, hereby represents and warrants to, and agrees with, the Company:

that the Investor is purchasing as principal, or is deemed to be purchasing as principal under the Securities Act (British Columbia) (the “B.C. Act”), and is an “accredited investor” as defined in Multilateral Instrument 45-103 Capital Raising Exemptions (“MI 45-103”) and the Investor has completed and executed the British Columbia and Alberta Accredited Investor Certificate attached hereto as Appendix II and confirms the truth and accuracy of all statements made therein by the Investor.

2. If the Investor is a resident of, incorporated under or otherwise subject to the laws of the Province of Ontario, the Investor is an “accredited investor” as that term is defined in Ontario Securities Commission Rule 45-501, and the Investor has completed and executed the Ontario Accredited Investor Certificate attached hereto as Appendix III to this Subscription Agreement and confirms the truth and accuracy of all statements made therein by the Investor;

3. the Units and any securities of the Public Company acquired following the Reorganization will be subject to resale or transfer restrictions, including the following:

(i)

the Units or any Public Company securities will be subject to resale restrictions under applicable securities legislation;

(ii)

the Investor will not be able to resell, assign or otherwise dispose of the Units or any Public Company securities unless they are subsequently distributed under a prospectus or in compliance with all applicable resale restrictions;

(iii)

the Company may be required to legend the certificates representing the Units or any Public Company securities regarding these and any other restrictions on resale; and

(iv)

the Company is under no obligation to qualify the resale of the Units or any Public Company securities under a prospectus, or assist the Investor in

complying with any exemption from the prospectus requirement or resale restrictions set out under applicable securities legislation.

D.	UNDERSTANDINGS.

The Investor understands, acknowledges and agrees with the Company as follows:

1. This Subscription may be rejected, in whole or in part, by the Company, in its sole and absolute discretion, at any time before the Final Closing, notwithstanding prior receipt by the Investor of notice of acceptance of the Investor’s Subscription.

2. This Subscription is and shall be irrevocable, except that the Investor shall have no obligations hereunder in the event that this Subscription is rejected in full for any reason.

3. No Federal or state agency has made any finding or determination as to the accuracy or adequacy of the Memorandum or as to the fairness of the terms of this offering for investment, nor any recommendation or endorsement of the Units.

4. The offering and sale of the Units is intended to be exempt from registration under the Act by virtue of Section 4(2) of the Act, and Rule 506 thereunder, which is in part dependent upon the truth, completeness and accuracy of the statements made by the Investor herein and in the Questionnaire.

5. The Company currently is a private company whose shares have not been registered with any governmental agency. In addition, the offer and sale of the Shares under the Memorandum have not been registered. Accordingly, the Common Stock contained in the Units will not be freely transferable. In the Reorganization, the Company will exchange the Shares for shares of common stock of the Public Company. The shares of the Public Company’s stock that an Investor will receive in the Reorganization will also not be registered or freely transferable, and unless those shares are registered sooner, cannot be publicly resold for at least one year after the date of the Reorganization. Although the Public Company will be required to file a registration statement within 90 days following the Final Closing to register the Shares and shares of Common Stock issuable upon exercise of the Warrants, the Public Company may encounter delays in completing this registration and the Investor may have to bear the economic risk of his investment in the Units for an indefinite period of time. Although the Public Company’s shares are eligible for trading on the OTC-Other Market, there may not be a significant market in such stock in the future. In addition, there can be no assurance that a regular and established market will be developed and maintained for the securities upon completion of the Reorganization and this Offering. There can also be no assurance as to the depth or liquidity of any market for the Public Company’s common stock or the prices at which holders may be able to sell the shares.

6. If the Company decides to use any placement agents, each of the placement agents will receive compensation in connection with the offering and sale of the Units but none of them will guarantee or assume responsibility for the operation or possible liability of the Company, and none of them will supervise or participate in the operation or management of the Company.

7. The Investor understands that, in connection with the Reorganization, the Company will conduct a limited due diligence investigation of the Public Company, including a reasonable investigation of the Public Company’s assets and liabilities, management and operations. The Investor acknowledges that, notwithstanding the Company’s due diligence investigation, undiscovered liabilities and other problems with the Public Company may subsequently arise that will affect the

value of the shares of the Public Company’s securities that the Investor will receive following the Reorganization. The Investor acknowledges that in making its investment in the Units it is not relying upon any due diligence investigation of the Company to detect the Public Company’s undisclosed liabilities or problems.

8. The Investor acknowledges that no general solicitation or general advertising (including, without limitation, communications published in any newspaper, magazine or other broadcast) has been received by him and that no public solicitation or advertisement with respect to the offering of the Units has been made to him.

9. The Investor acknowledges that the information contained in the Memorandum is confidential and non-public and agrees that all such information shall be kept in confidence by the Investor and neither used by the Investor for the Investor’s personal benefit (other than in connection with this Subscription) nor disclosed to any third party for any reason; provided, however, that this obligation shall not apply to any such information that (i) is part of the public knowledge or literature and readily accessible at the date hereof, (ii) becomes part of the public knowledge or literature and readily accessible by publication (except as a result of a breach of this provision) or (iii) is received from third parties (except third parties who disclose such information in violation of any confidentiality agreements or obligations). The Investor acknowledges that the information contained in the Memorandum regarding the Reorganization is non-public information and is material in nature. The applicable provisions of the United States Federal and state securities laws, particularly Rule 10b-5 promulgated under the Securities Exchange Act of 1934, as amended, prohibit the purchase or sale of publicly traded securities on the basis of material non—public information. Accordingly, the Investor agrees not to purchase or sell shares of the Public Company until the Reorganization has been completed and has been fully disclosed to the public and the Securities and Exchange Commission.

10. IN MAKING AN INVESTMENT DECISION PURCHASERS MUST RELY ON THEIR OWN EXAMINATION OF THE COMPANY AND THE TERMS OF THE OFFERING, INCLUDING THE MERITS AND RISKS INVOLVED. THESE UNITS HAVE NOT BEEN RECOMMENDED BY ANY FEDERAL OR STATE OR FOREIGN SECURITIES COMMISSION OR REGULATORY AUTHORITY. FURTHERMORE, THE FOREGOING AUTHORITIES HAVE NOT CONFIRMED THE ACCURACY OR DETERMINED THE ADEQUACY OF THE MEMORANDUM OR THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

11. THE UNITS (INCLUDING THE SHARES OF COMMON STOCK, WARRANTS AND WARRANT SHARES CONTAINED THEREIN) MAY NOT BE TRANSFERRED, RESOLD OR OTHERWISE DISPOSED OF EXCEPT AS PERMITTED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933 OR UNDER APPLICABLE STATE SECURITIES LAWS. PURCHASERS SHOULD BE AWARE THAT THEY WILL BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.

12. FOR RESIDENTS OF ALL STATES. THE SECURITIES OFFERED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE AND ARE BEING OFFERED AND SOLD IN RELIANCE ON EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND SUCH LAWS. THE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER

SAID ACT AND SUCH LAWS PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. THE CERTIFICATES EVIDENCING THE SECURITIES SHALL BEAR A RESTRICTIVE LEGEND REFLECTING THE FOREGOING AND REQUIRING THE TRANSFEROR TO PROVIDE AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY FOR ANY TRANSFER PURSUANT TO AN EXEMPTION UNDER THE ACT. INVESTORS SHOULD BE AWARE THAT THEY WILL BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.

13. ANY UNITS PURCHASED BY RESIDENTS OF BRITISH COLUMBIA, ALBERTA OR ONTARIO WILL BE SUBJECT TO RESALE RESTRICTIONS IMPOSED UNDER THE SECURITIES LAWS OF THOSE PROVINCES AND MAY ONLY BE SOLD PURSUANT TO AN AVAILABLE EXEMPTION.

4. Failure of the Company to exercise any right or remedy under this Subscription Agreement or any other agreement between the Company and the Investor, or otherwise, or delay by the Company in exercising such right or remedy, will not operate as a waiver thereof. No waiver by the Company will be effective unless and until it is in writing and signed by the Company.

6. The Investor hereby irrevocably nominates, constitutes and appoints the President of the Company as his, her or its agent and true and lawful attorney to act on his, her or its behalf, whether in the best interest of the Investor or otherwise, with full power and authority in his, her or its

name, place and stead to execute, under seal or otherwise, swear to, acknowledge, deliver and file or record when, as and where required:

Unless otherwise stated, all Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the Holders of such securities pro rata on the basis of the number of shares so registered or proposed to be so registered.

2.3 Registration Procedures. In the case of the registration effected by the Public Company pursuant to this Exhibit, the Public Company will keep each Holder advised in writing as to the initiation of such registration and as to the completion thereof. The Public Company will:

(a) Prepare and file with the Commission a registration statement and such amendments and supplements as may be necessary and use its commercially reasonable best efforts to cause such registration statement to become and remain effective until (i) the first anniversary following the date the registration statement is declared effective, or (ii) all of the Registrable Securities included in the registration statement have been sold, whichever comes first, except that the Public Company shall be permitted to suspend the use of the registration statement during certain periods as set forth below in this Section 2.3;

(b) Furnish to the Holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as such underwriters may reasonably request in order to facilitate the public offering of such securities;

Notwithstanding the foregoing, the Public Company shall notify each Holder whose securities are included in a registration of the happening of any event which makes any statement made in the registration statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or which requires the making of any changes in the

registration statement or prospectus so that, in the case of the registration statement, it will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the prospectus, it will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. In such event, the Public Company may suspend use of the prospectus on written notice to each participating Holder, in which case each participating Holder shall not dispose of Registrable Securities covered by the registration statement or prospectus until copies of a supplemented or amended prospectus are distributed to the participating Holders or until the participating Holders are advised in writing by the Public Company that the use of the applicable prospectus may be resumed (the period of such suspension shall be a “Blackout Period”). The Public Company shall ensure that the use of the prospectus may be resumed as soon as is reasonably practicable. The Public Company shall, upon the occurrence of any event contemplated by this paragraph, prepare a supplement or post-effective amendment to the registration statement or a supplement to the related prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such prospectus will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. In the event that the Public Company declares one or more Blackout Periods, the one-year anniversary period set forth in Section 2.3(a) shall be extended by the number of days that constitute any such Blackout Periods.

2.4 Indemnification.

(a) The Public Company will indemnify each Holder, each of its officers and directors and partners, and each person controlling such Holder within the meaning of Section 12 of the Securities Act, with respect to which registration has been effected pursuant to this Exhibit, against all expenses, claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or any violation by the Public Company of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Public Company in connection with any such registration, and the Public Company will reimburse each such Holder, each of its officers and directors, and each person controlling such Holder, for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that the Public Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Public Company by or on behalf of such Holder for use therein.

(b) Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration is being effected, indemnify the Public Company, each of its officers and directors, each person who controls the Public Company within the meaning of Section 15 of the Securities Act, each other holder of the Public Company’s securities covered by such registration statement, and each such holder’s officers and directors and each person controlling such holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or

other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Holder of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Holder, and will reimburse the Public Company, such other holders, such officers, directors, or control persons for any legal or any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating or defending any such claim, loss, damage, liability or action, but in the case of the Public Company or the other holders or their officers, directors, or control persons, only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with information furnished to the Public Company in writing by such Holder. Notwithstanding the foregoing, the liability of each Holder under this Section 2.4(b) shall be limited to an amount equal to the net proceeds from the offering received by such Holder. A Holder will not be required to enter into any agreement or undertaking in connection with any registration under this Section 2 providing for any indemnification or contribution on the part of such Holder greater than the Holder’s obligations under this Section 2.4(b).

(c) Each party entitled to indemnification under this Section 2.4 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Exhibit unless the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action and provided further, that the Indemnifying Party shall not assume the defense for matters as to which there is a conflict of interest or there are separate and different defenses. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (whose consent shall not be unreasonably withheld), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(d) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

3. Transfer of Rights. The rights granted under Section 2 of this Exhibit may be assigned to any transferee or assignee in connection with any transfer or assignment by the Holder of such Holder’s Warrants or Registrable Securities, provided that: (i) such transfer is otherwise effected in accordance with applicable securities laws and the terms of this Exhibit; (ii) written notice is promptly given to the Public Company; and (iii) such transferee or assignee agrees in writing to be bound by the provisions of this Exhibit and by any other agreement reasonably necessary to ensure compliance with the Federal and state securities laws.
