The Company hereby represents and warrants to the Purchaser as of the date of this Agreement as set forth below except as disclosed in the Company's filings under the Securities Exchange Act of 1934 (collectively, the "Exchange Act Filings"), or the Schedules hereto.

2.1 Organization, Good Standing and Qualification. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the jurisdiction of its incorporation and is qualified to do business and in good standing in each other jurisdiction in which the ownership or leasing of its properties or the nature of its business requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect. As used in this Agreement, "Material Adverse Effect" means any material adverse effect on the business, properties, assets, operations, results of operations or financial condition of the Company, or on the transactions contemplated hereby, or by the other Transaction Documents (as that term is defined herein) or the agreements and instruments to be entered into in connection herewith or therewith, or on the authority or ability of the Company to perform its obligations under the Transaction Documents.

2.2 Subsidiaries. Schedule 2.2 hereto sets forth each subsidiary of the Company, showing the jurisdiction of its incorporation or organization and showing the percentage of each person's ownership of the outstanding stock or other interests of such subsidiary. For the purposes of this Agreement, "subsidiary" shall mean any corporation or other entity of which at least a majority of the securities or other ownership interest having ordinary voting power (absolutely or contingently) for the election of directors or other persons performing similar functions are at the time owned directly or indirectly by the Company and/or any of its other subsidiaries. All of the outstanding shares of capital stock of each subsidiary (that is a corporation) have been duly authorized and validly issued, and are fully paid and nonassessable. There are no outstanding preemptive, conversion or other rights, options, warrants or agreements granted or issued by or binding upon any subsidiary for the purchase or acquisition of any shares of capital stock of any subsidiary or any other securities convertible into, exchangeable for or evidencing the rights to subscribe for any shares of such capital stock. Neither the Company nor any subsidiary is subject to any obligation (contingent or otherwise) to repurchase or otherwise acquire or retire any shares of the capital stock of any subsidiary or any convertible securities, rights, warrants or options of the type described in the preceding sentence. Neither the Company nor any subsidiary is party to, nor has any knowledge of, any agreement restricting the voting or transfer of any shares of the capital stock of any subsidiary.

The financial statements of the Company included in the SEC Reports comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC or other applicable rules and regulations with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") applied on a consistent basis during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed) and fairly present in all material respects the financial position of the Company and its subsidiaries as of the dates thereof and the results of operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments).

2.24 No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would cause the offering of the Securities pursuant to this Agreement to be integrated with prior offerings by the Company for purposes of the 1933 Act which would prevent the Company from selling the Securities pursuant to Rule 506 under the 1933 Act, or any applicable exchange-related stockholder approval provisions, nor will the Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings.

2.25 Stop Transfer. The Securities are restricted securities as of the date of this Agreement. The Company will agree to promptly cause to be removed any stop transfer order or other order impeding the sale and delivery of any of the Securities at such time as the Securities are resold if such securities are registered for public sale, whether as a result of the Registration Rights Agreement or otherwise, or an exemption from registration is available and the conditions for use thereof are satisfied, except as required by federal securities laws.

2.27 Material Agreements. There is no agreement that has not been filed with the SEC as an exhibit to a registration statement or other applicable form the breach of which could reasonably be expected to have a material adverse effect as to the Company and its subsidiaries, or would prohibit or otherwise interfere with the ability of the Company to enter into and perform any of its obligations under this Agreement in any material respect.

2.28 ERISA. Based upon the Employee Retirement Income Security Act of 1974 ("ERISA"), and the regulations and published interpretations thereunder: (i) the Company has not engaged in any Prohibited Transactions as defined in Section 406 of ERISA and Section 4975 of the Internal Revenue Code, as amended; (ii) the Company has met all applicable minimum funding requirements under Section 302 of ERISA in respect of its plans; (iii) the Company does not have any knowledge of any event or occurrence which would cause the Pension Benefit Guaranty Corporation to institute proceedings under Title IV of ERISA to terminate any employee benefit plan(s); (iv) the Company does not have any fiduciary responsibility for investments with respect to any plan existing for the benefit of persons other than Companies' employees; and (v) the Company has not withdrawn, completely or partially, from any multi-employer pension plan so as to incur liability under the Multiemployer Pension Plan Amendments Act of 1980.

2.29 Solvency. After taking into account the proceeds received by the Company, from the transactions contemplated hereby, the Company is solvent, able to pay its debts as they mature, has capital sufficient to carry on its business and all businesses in which such Company is about to engage and the fair saleable value of its assets (calculated on a going concern basis) is in excess of the amount of its liabilities.

3. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.

The Purchaser hereby represents and warrants to the Company as follows:

3.1 Requisite Power and Authority. The Purchaser has all necessary power and authority under all applicable provisions of law to execute and deliver this Agreement and the Transaction Documents and to carry out their provisions. All corporate action on Purchaser's part required for the lawful execution and delivery of this Agreement and the Transaction Documents have been or will be effectively taken prior to the Closing. Upon their execution and delivery, this Agreement and the other Transaction Documents will be valid and binding obligations of the Purchaser, enforceable in accordance with their terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting enforcement of creditors' rights, and (b) as limited by general principles of equity that restrict the availability of equitable and legal remedies.

3.2 Investment Representations. The Purchaser understands that the Securities are being offered and sold pursuant to an exemption from registration contained in the 1933 Act based in part upon the Purchaser's representations contained in this Agreement, including, without limitation, that the Purchaser is an "accredited investor" within the meaning of Regulation D. The Purchaser has had an opportunity to ask questions and receive answers from the Company regarding the Company's business, management and financial affairs and the terms and conditions of the offering and the Securities and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to the Purchaser or to which the Purchaser had access.

3.3 Purchaser Bears Economic Risk. The Purchaser has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. The Purchaser must bear the economic risk of this investment until the Securities are sold pursuant to (i) an effective registration statement under the 1933 Act, or (ii) an exemption from registration is available.

3.4 Acquisition for Own Account. The Purchaser is acquiring the Note and the Warrant its own account for investment only, and not as a nominee or agent and not with a view towards or for resale in connection with their distribution.

3.5 Purchaser Can Protect Its Interest. The Purchaser represents that by reason of its, or of its management's, business and financial experience, the Purchaser has the capacity to evaluate the merits and risks of its investment in the Securities and to protect its own interests in connection with the transactions contemplated in this Agreement, and the other Transaction Documents. Further, the Purchaser is aware of no publication of any advertisement in connection with the transactions contemplated in the Agreement or the other Transaction Documents. The Purchaser understands that an investment in the Company involves a high degree of risk for the reasons, among others, set forth on Schedule 3.5 attached hereto.

3.6 Accredited Investor. The Purchaser represents that it is an accredited investor within the meaning of Regulation D.

3.7 Legends.

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR IF APPLICABLE, STATE SECURITIES LAWS. THESE SHARES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH SECURITIES ACT AND APPLICABLE STATE LAWS OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO STOCKERYALE, INC. THAT SUCH REGISTRATION IS NOT REQUIRED."

(b) The Warrant shall bear substantially the following legend:

"THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THIS WARRANT MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THIS WARRANT OR THE UNDERLYING SHARES OF COMMON STOCK UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO STOCKERYALE, INC. THAT SUCH REGISTRATION IS NOT REQUIRED."

3.8 Market Manipulation. The Purchaser has not taken, and will not take, directly or indirectly, any action designed to, or that might reasonably be expected to, cause or result in stabilization or manipulation of the price of the Common Stock of the Company to facilitate the sale or resale of any of the Securities being offered hereby or affect the price at which any of the Securities being offered hereby may be issued. Notwithstanding the foregoing, nothing contained herein shall limit or be deemed in any manner whatsoever to limit any Purchaser hedging transactions following payment in full of the Note.

4. COVENANTS OF THE COMPANY.

The Company covenants and agrees with the Purchaser as follows:

4.1 Stop-Orders. The Company will advise the Purchaser, promptly after it receives notice of issuance by the SEC, any state securities commission or any other regulatory authority of any stop order or of any order preventing or suspending any offering of any securities of the Company, or of the suspension of the qualification of the Common Stock of the Company for offering or sale in any jurisdiction, or the initiation of any proceeding for any such purpose.

4.2 Listing. The Company will use commercially reasonable efforts to maintain the listing of its Common Stock on the Nasdaq Stock Market (including the Nasdaq SmallCap Market and the Nasdaq OTC Bulletin Board, but excluding the pink and yellow sheets), American Stock Exchange or New York Stock Exchange (a "Principal Market"), and will comply in all material respects with the Company's reporting, filing and other obligations under the bylaws or rules of the National Association of Securities Dealers ("NASD") and such exchanges, as applicable. The Company will provide the Purchaser copies of all notices it receives notifying the Company of the threatened and actual delisting of the Common Stock from any Principal Market.

4.3 Market Regulations. The Company shall notify the SEC, NASD and applicable state authorities, in accordance with their requirements, of the transactions contemplated by this Agreement, and shall take all other necessary action and proceedings as may be required and permitted by applicable law, rule and regulation, for the legal and valid issuance of the Securities to the Purchaser and promptly provide copies thereof to the Purchaser.

4.4 Reporting Requirements. The Company will timely file with the SEC all reports required to be filed pursuant to the Exchange Act and refrain from terminating its status as an issuer required by the Exchange Act to file reports thereunder even if the Exchange Act or the rules or regulations thereunder would permit such termination. Within fifteen (15) days after the end of each month, the Company will deliver to the Purchaser unaudited trial balances as at the end of such month.

4.5 Use of Funds. The Company agrees that it will use the proceeds of the sale of the Note and Warrant for general corporate purposes and the purposes set forth on Schedule 4.5 hereto and will not use any of such proceeds to repay any indebtedness of the Company (other than trade payables in the ordinary course) to any current executive officers, directors or principal stockholders of the Company.

4.6 Access to Facilities. The Company will permit any representatives designated by the Purchaser (or any transferee of the Purchaser), upon reasonable notice and during normal business hours, at such person's expense and accompanied by a representative of the Company, to (a) visit and inspect any of the properties of the Company, (b) examine the corporate and financial records of the Company (unless such examination is not permitted by federal, state or local law or by contract) and make copies thereof or extracts therefrom and (c) discuss the affairs, finances and accounts of any such corporations with the directors, officers and independent accountants of the Company.

4.7 Offering Restrictions. Except as previously disclosed in the SEC Reports or in the Exchange Act Filings, or stock or stock options granted to employees or directors of the Company; or equity or debt issued in connection with an acquisition of a business or assets by the Company; or the issuance by the Company of stock in connection with the establishment of a joint venture partnership or licensing arrangement (these exceptions hereinafter referred to as the "Excepted Issuances"), the Company will not issue any securities with a variable/floating conversion feature which are or could be (by conversion or registration) free-trading securities (i.e., common stock subject to a registration statement) prior to the full repayment or conversion of the Note. For the avoidance of doubt, the parties acknowledge and agree that the inclusion of customary antidilution provisions in securities will not constitute a variable/floating rate conversion feature.

4.8 Insurance. The Company will keep its assets which are of an insurable character insured by financially sound and reputable insurers against loss or damage by fire, explosion and other risks customarily insured against by companies in similar business similarly situated as the Company; and the Company will maintain, with financially sound and reputable insurers, insurance against other hazards and risks and liability to persons and property to the extent and in the manner customary for companies in similar business similarly situated as the Company and to the extent available on commercially reasonable terms.

4.9 Intellectual Property; Corporate Existence. The Company shall maintain in full force and effect its corporate existence, rights and franchises and all licenses and other rights to use Intellectual Property owned or possessed by it and reasonably deemed to be necessary to the conduct of its business.

4.10 Financial Information. The Company agrees to send the following to the Purchaser: (i) unless the following are filed with the SEC through EDGAR and are available to the public through EDGAR, within one (1) day after the filing thereof with the SEC, a copy of its Annual Report on Form 10-K, as amended, its Quarterly Reports on Form 10-Q, any Current Reports on Form 8-K and any registration statements (other than on Form S-8) or amendments filed pursuant to the 1933 Act; (ii) on the same day as the release thereof, facsimile copies of all press releases issued by the Company or any of its Subsidiaries, unless available through Bloomberg Financial Markets (or any successor thereto) contemporaneously with the release; and (iii) copies of any notices and other information made available or given to the stockholders of the Company generally, contemporaneously with the making available or giving thereof to the stockholders.

4.11 Reservation of Shares. The Company shall take all action necessary to at all times have authorized, and reserved for the purpose of issuance, no less than 110% of the number of shares of Common Stock needed to provide for the issuance of the Conversion Shares upon conversion of the entire outstanding Note (without regard to any limitations on conversions) and 110% of the number of shares of Common Stock needed to provide for the issuance of the Warrant Shares upon exercise of all outstanding Warrant (without regard to any limitations on exercises).

4.12 Confidentiality. The Company agrees that it will not disclose, and will not include in any public announcement, the name of the Purchaser, unless expressly agreed to by the Purchaser or unless and until such disclosure is required by law or applicable regulation, and then only to the extent of such requirement.

4.13 Corporate Existence. So long as the Purchaser beneficially owns any of the Securities, the Company shall maintain its corporate existence and shall not sell all or substantially all of the Company's assets, except in the event of a merger or consolidation or sale or transfer of all or substantially all of the Company's assets where the surviving or successor entity in such transaction (i) assumes the Company's obligations hereunder and the Transaction Documents and (ii) is a publicly traded company whose common stock is quoted or listed on a Principal Market.

4.14 Reissuance of Securities. The Company agrees to reissue certificates representing the Securities without the legends set forth in Section 5.7 above at such time as (a) the holder thereof is permitted to dispose of such Securities pursuant to Rule 144(k) under the 1933 Act, or (b) upon resale subject to an effective registration statement after such Securities are registered under the 1933 Act. The Company agrees to cooperate with the Purchaser in connection with all resales pursuant to Rule 144(d) and Rule 144(k) and, subject to satisfaction of all requirements of such rules, to provide legal opinions or such transfer agent instructions necessary to allow such resales provided the Company and its counsel receive reasonably requested representations from the selling Purchaser and broker, if any.

4.15 Priority of Notes. Except as set forth in Section 1.4 hereof and on Schedule 4.15 hereto, for so long as the Note is outstanding, in the event that the Company or any of its Subsidiaries issues or incurs any indebtedness, it shall, or it shall cause any Subsidiary to, first enter into, and cause the lender to enter into, a Subordination Agreement, containing terms and conditions acceptable to the Purchaser.

4.16 Expenses and Other Payments. The Company shall reimburse the Purchaser for its reasonable legal fees for services rendered to the Purchaser in preparation of this Agreement and the other Transaction Documents, and expenses in connection with the Purchaser's due diligence review of the Company and relevant matters, subject to reasonable documentation of such expenses. Amounts payable hereunder and under Section 6.10 of the Note shall be withheld by the Purchaser from the Purchase Price to be paid at Closing.

4.17 Transfer and Depositary Agent Instructions. Other than as provided below, all certificates issued for Conversion Shares or Warrant Shares shall bear the restrictive legend specified in Section 3.7. The Company warrants that the Securities shall be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the Registration Rights Agreement, other than in accordance with applicable securities laws. If the Purchaser provides the Company with an opinion of counsel, in a form reasonably acceptable to the Company, to the effect that a public sale, assignment or transfer of the Securities may be made without registration under the 1933 Act or the Purchaser provides the Company with reasonable assurances that the Securities can be sold pursuant to Rule 144 without any restriction as to the number of securities acquired as of a particular date that can then be immediately sold, the Company shall permit the transfer, and, in the case of the Conversion Shares and the Warrant Shares, promptly instruct its transfer agent to issue one or more certificates in such name and in such denominations as specified by the Purchaser and without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Purchaser by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 4.18 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.18, that the Purchaser shall be entitled, in addition to all other available remedies but subject to applicable securities laws, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

4.18 Pro Rata Requirement. The Company hereby agrees that if the Company takes any action or omits to take any action in connection with or relating to any of the Transaction Documents, including, without limitation, any prepayments, redemptions, repayments, conversions, determinations as to payments in cash or stock or a combination of stock or cash or otherwise, then it must simultaneously take the similar action or omission, pro rata as applicable, with respect to the documents having substantially identical terms to the Transaction Documents issued and entered into on the date hereof with Smithfield Fiduciary LLC (the "Other Investor Transaction Documents" and collectively with the Transaction Documents, the "December Transaction Documents"). Neither the Company nor any other person shall offer or pay any consideration to any person to amend or consent to a waiver or modification of any provision of any of the Other Investor Transaction Documents unless the same consideration also is offered to the Purchaser or its designee. The Company has not, directly or indirectly, made any agreements with any person relating to the terms or conditions of the transactions contemplated by the December Transaction Documents except as set forth in the December Transaction Documents. The terms of the Other Investor Transaction Documents are substantially identical to the terms of the Transaction Documents (other than the conditions to funding).

7. COVENANTS OF THE COMPANY AND THE PURCHASER REGARDING INDEMNIFICATION.

7.1 Company Indemnification. The Company agrees to indemnify, hold harmless, reimburse and defend the Purchaser, each of the Purchaser's officers, directors, agents, affiliates, control persons, and principal shareholders, against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed upon the Purchaser which results, arises out of or is based upon the negotiation, execution or performance of this Agreement including but not limited to (i) any misrepresentation by Company or breach of any warranty by Company in this Agreement or in any exhibits or schedules attached hereto or any Transaction Document, or (ii) any breach or default in performance by Company of any covenant or undertaking to be performed by Company hereunder, or any other agreement entered into by the Company and the Purchaser relating hereto.

7.2 Purchaser's Indemnification. The Purchaser agrees to indemnify, hold harmless, reimburse and defend the Company and each of the Company's officers, directors, agents, affiliates, control persons and principal shareholders, at all times against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees incurred in the defense thereof) of any nature, incurred by or imposed upon the Company which results, arises out of or is based upon any breach of the representations of the Purchaser contained in Section 3 of this Agreement.

7.3 Procedures. Promptly after receipt by an indemnified party pursuant to the provisions of Section 7.1 or 7.2 of notice of the commencement of any action involving the subject matter of the foregoing indemnity provisions such indemnified party will, if a claim thereof is to be made against the indemnifying party pursuant to the provisions of Section 7.1 or 7.2, promptly notify the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise under this Section except to the extent the defense of the claim is prejudiced. In case such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to participate in, and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, provided, however, if counsel for the indemnifying party concludes that a single counsel cannot under applicable legal and ethical considerations, represent both the indemnifying party and the indemnified party, the indemnified party or parties have the right to select separate counsel to participate in the defense of such action on behalf of such indemnified party or parties; provided that there shall be no more than one such separate counsel. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party pursuant to the provisions of said Section 7.1 or 7.2 for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, unless (i) the indemnified party shall have employed counsel in accordance with the provisions of the preceding sentence, (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after the notice of the commencement of the action or (iii) the indemnifying party has, in its sole discretion, authorized the employment of counsel for the indemnified party at the expense of the indemnifying party.

8. MISCELLANEOUS.

8.1 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to principles of conflicts of laws.

In the event that any provision of this Agreement or any other agreement delivered in connection herewith is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of any agreement.

8.2 Survival.

8.5 Severability. In case any provision of the Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

8.6 Amendment and Waiver.

(a) This Agreement may be amended or modified only upon the written consent of the Company and the Purchaser.

(b) The obligations of the Company and the rights of the Purchaser under this Agreement may be waived only with the written consent of the Purchaser.

It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or non-compliance by another party under this Agreement or the Transaction Documents, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.
