(c) The Corporation shall not be obligated to effect, or to take any action to effect, any such Registration pursuant to Section 2(a) if:

(i) the Corporation shall furnish to the Stockholders a certificate signed by the President of the Corporation stating that in the good faith judgment of the Board, the effect of the Demand Registration would materially impede the ability of the Corporation to consummate a significant transaction or there exists at the time of the request specified in Section 2(a) material non-public information relating to the Corporation the disclosure of which would be seriously detrimental to the Corporation and that it is in the best interests of the Corporation to defer the filing of a registration statement in respect of the demand Registration until a date that is not more than 90 days from the date of receipt of the request specified in Section 2(a); provided however, that the Corporation shall not defer its obligation in this manner pursuant to this Section 2(c)(i) more than once in any 12 month period; or

(ii) at the time of such request, the Corporation is engaged in a self-tender or exchange offer and the filing of a Prospectus would cause a violation of the Exchange Act or applicable Canadian Securities Laws; or

(iii) within 30 days of receipt of a written request that the Corporation effect a demand Registration pursuant to Section 2(a), the Corporation delivers a written notice to all holders of Registrable Shares of its intent to file a Prospectus for its Initial Registration within 90 days of the Corporation’s receipt of such written request; provided, however, that the Corporation shall not defer its obligation pursuant to this Section 2 (c) (iii) more than once in any 12 month period; or

(iv) such demand Registration will be completed within the 90 day period commencing on the date of any Registration in which the Stockholders were entitled (subject to underwriter cutbacks) to include Registrable Shares pursuant to this Agreement; or

(v) such demand Registration will be completed within the 180 day period commencing on the date of the Corporation’s Initial Registration.

(d) If the Demanding Investors so elect, the Registration of the Registrable Shares shall be in the form of an underwritten offering. The Stockholders (Demanding Investors and non-Demanding Investors) holding a majority of the Registrable Shares requested to be included in such Registration shall select one or more nationally recognized firms of investment bankers reasonably acceptable to the Corporation to act as the lead managing underwriter or underwriters in connection with such offering.

(e) At any time before the registration statement covering Registrable Shares pursuant to Section 2(a) becomes effective, the holders of a majority of the Registrable Shares requested to be included in such Registration (Demanding Investors and non-Demanding Investors) may request the Corporation to withdraw or not to file the registration statement. In that event, unless such request of withdrawal was caused by, or made (A) as a result of a delay pursuant

to Section 2(c) above, (B) in response to, the material adverse effect of an event on the business, properties, condition, financial or otherwise, or operations of the Corporation not actually known (without imputing the knowledge of any other Person to such holders) by a majority of such holders at the time the initial written request of the Demanding Investors was made, or (C) in response to material information with respect to the Corporation not actually known (without imputing the knowledge of any other Person to such holders) by a majority of such holders at the time the initial written request of the Demanding Investors was made, which material information would make it inadvisable or difficult to effect such Registration, then the holders shall be deemed to have used one of their Long-Form Registrations permitted under Section 2(a) and the Corporation shall no longer be obligated to Register Registrable Shares pursuant to the exercise of such Long-Form Registration pursuant to Section 2(a) unless the holders of Registrable Shares reimburse the Corporation for the expenses incurred by the Corporation through the date of the Corporation’s receipt of such request to withdraw or not file the Prospectus.

Section 3. Piggyback Registration.

(a) If the Corporation proposes for any reason to Register Primary Shares under the Securities Act and/or the Canadian Securities Laws (including the Initial Registration), it shall give written notice to the Stockholders of its intention to so register such Primary Shares at least thirty (30) days before the initial filing of the registration statement and, upon the written request, delivered to the Corporation within twenty (20) days after delivery of any such notice by the Corporation, of the Stockholders to include in such Registration of Registrable Shares (which request shall specify the number of Registrable Shares proposed to be included in such Registration and shall state that such Stockholders desire to sell such Registrable Shares in the public securities markets), the Corporation shall use its best efforts to cause all such Registrable Shares to be included in such Registration on the same terms and conditions as the securities otherwise being sold in such Registration; provided, however, that if the managing underwriter, if any, advises the Corporation that the inclusion of all Registrable Shares requested to be included in such Registration would be materially detrimental to the successful marketing (including pricing) of the Primary Shares proposed to be included in such Registration, then the number of Primary Shares and Registrable Shares proposed to be included in such Registration shall be included in the following order:

(i) first, the Primary Shares; and

(ii) second, the Preferred Registrable Shares and the Prior Common Registrable Shares requested to be included in such Registration pro rata among the holders thereof based on the number of Registrable Shares requested to be included in such Registration by each such holder.

(b) For the purposes of cutbacks pursuant to this Section 3, in no event shall the aggregate amount of the Registrable Shares held by the Series C Investors and Series A Investors included in the registration be reduced below 20% of the aggregate amount of securities included in such registration, except with respect to registration of securities in connection with the Corporation’s Initial Registration wherein the aggregate amount of Registrable Shares held by the Series C Investors and Series A Investors included in the registration may be reduced to zero. In the event the Registrable Shares held by the Series C Investors and the Series A Investors is so limited to 20% as set forth in this Section 3(b), then no other Stockholder shall be allowed to sell any Registrable Shares in such registration.

Section 4. Short-Form Demand Registration.

(a) After such time as the Corporation has completed an Initial Registration, it shall use its best efforts to become eligible, and to thereafter remain eligible, to satisfy all of the requirements for use of a Short-Form Registration other than the reporting history requirement and the public float requirement. Anything contained in Section 2 to the contrary notwithstanding, at such time as the Corporation shall have qualified for the use of a Short-Form Registration, the holders of the Series C Preferred Registrable Shares then outstanding, the holders of the Series A Preferred Registrable Shares then outstanding and the holders of Prior Common Registrable Shares then outstanding shall have the right to request in writing an unlimited number of Short-Form Registrations, which written request or requests shall (i) specify the number of Registrable Shares intended to be sold or disposed of and the holders thereof, (ii) state the intended method of disposition of such Registrable Shares and (iii) relate to Registrable Shares having an aggregate offering price of at least two million dollars ($2,000,000). The Corporation shall not be obliged to effect more than two registrations in any 12-month period. A request for a Short-Form Registration shall not count as a Long-Form Registration initiated pursuant to Section 2(a).

(b) If the Corporation shall receive a written request that the Corporation effect any Registration pursuant to Section 4 (a) with respect to all or a part of the Registrable Shares, the Corporation will:

(i) within ten Business Days of such receipt, give written notice of the proposed Registration to all the Stockholders; and

(ii) use its best efforts to effect such Registration (including, without limitation, filing post-effective amendments and appropriate qualifications under the applicable securities laws of the United States and the Canadian Securities Laws) as soon as practicable, but in any event, subject to Section 2(c), file or cause to be filed a registration statement within ninety (90) days after the receipt by the Corporation of the written request to effect any such Registration, and as would permit or facilitate the Registration of all or such portion of such Registrable Shares as are specified in such request, together with all or such portion of the Registrable Shares of any Stockholder or Stockholders joining in such request as are specified in a written request received by the Corporation

within 20 days after the written notice from the Corporation described in Section 4(b)(i) is delivered by the Corporation. [Notwithstanding any other provision contained herein, if the managing underwriter, if any, determines in good faith that marketing factors require a limitation of the number of securities of the Corporation to be underwritten, no Registrable Shares will be so excluded unless the underwriter first excludes all other securities of the Corporation proposed to be included in such Registration (including securities for the account of the Corporation) and the underwriter shall then allocate the number of Registrable Shares in the following order:

(A) first, the Primary Shares; and

(B) second, the Preferred Registrable Shares and the Prior Common Registrable Shares requested to be included in such Registration pro rata among the holders thereof based on the number of Registrable Shares requested to be included in such Registration by each such holder.

Section 5. Lock-Up Agreement.

In connection with the Initial Registration, each Stockholder agrees that he, she or it, shall, upon request of the managing underwriter, not sell publicly, make any short sale of, grant any option for the purchase of, or otherwise dispose publicly of, any shares of Common Stock (other than those shares of Common Stock included in such Registration) without the prior written consent of the managing underwriter, for a period (the “Lockup Period”) designated by the managing underwriter in writing to the Stockholders, which period shall not exceed 180 days after the effective date of the Prospectus, plus such period thereafter as may be necessary to comply with applicable National Association of Security Dealers, Inc. rules; provided, however, that each executive officer, director and holder of 1% or more of the Corporation’s outstanding capital stock must agree to a Lockup Period of at least the same duration. The Corporation shall obtain the agreement of any person permitted to sell shares of stock in a Registration to be bound by and to comply with this Section 5 as if such person was a Stockholder hereunder. Notwithstanding the foregoing, in the event any of the agreements or restrictions set forth above are waived or terminated with respect to any holder of securities of the Corporation, then the foregoing provisions shall be waived or terminated with respect to each Series C Investor, Series A Investor and Prior Stockholder to the same extent.

Section 6. Preparation and Filing.

(a) If and whenever the Corporation is under an obligation pursuant to the provisions of this Agreement to use its best efforts to effect a Registration of any Registrable Shares, the Corporation shall as expeditiously as practicable:

(i) use its best efforts to prepare and file with the appropriate securities regulatory authorities a Prospectus and any other documents necessary, including amendments and supplements in respect of those documents, to permit the Registration and use its best efforts to keep such Registration effective for a period of 120 days or until the Stockholder or Stockholders have completed the Registration in compliance with all applicable securities laws, whichever first occurs;

(ii) furnish, at least five Business Days before filing a Prospectus or any amendments or supplements relating to such Prospectus, to one counsel selected by the holders of Registrable Shares requesting such Registration (the “Stockholders’ Counsel”), copies of all such documents proposed to be filed (it being understood that such five Business-Day period need not apply to successive drafts of the same document proposed to be filed so long as such successive drafts are supplied to the Stockholders’ Counsel in advance of the proposed filing by a period of time that is customary and reasonable under the circumstances);

(iii) prepare and file with the Commission such amendments and supplements to such Prospectus used in connection therewith as may be necessary to keep such Prospectus effective until all of such Registrable Shares have been disposed of and to comply with the provisions of the Securities Act and/or Canadian Securities Laws with respect to the Registration of such Registrable Shares;

(viii) notify each Stockholder holding Registrable Shares covered by a Prospectus on a timely basis at any time when a Prospectus relating to such Registrable Shares is required to be delivered under the Securities Act and/or Canadian Securities Laws of the occurrence of any material change or event as a result of which the Prospectus, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing and, promptly file such amendments and supplements which may be required on account of such change or event and use its best efforts to cause such amendment and supplement to become effective;

(ix) subject to the execution of confidentiality agreements in form and substance satisfactory to the Corporation, make available upon reasonable notice and during normal business hours, for inspection by the Stockholders holding such Registrable Shares, any underwriter participating in any Registration pursuant to such Prospectus and any attorney, accountant or other agent retained by the Series C Investors, Series A Investors and/or underwriter (collectively, the “Inspectors”), all pertinent financial and other records, pertinent corporate documents and properties of the Corporation (collectively, the “Records”), as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Corporation’s officers, directors and employees to supply all information (together with the Records, the “Information”) reasonably requested by any such Inspector in connection with such Prospectus. Any of the Information which the Corporation determines in good faith to be confidential, and of which determination the Inspectors are so notified, shall not be disclosed by the Inspectors unless (a) the disclosure of such Information is necessary to avoid or correct a material misstatement or omission in the Prospectus, (b) the release of such Information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or (c) such Information has been made

generally available to the public through no breach of the nondisclosure obligations of the Inspectors or their affiliates; the Series C Investors and Series A Investors agree that they will, upon learning that disclosure of such Information is sought in a court of competent jurisdiction, give notice to the Corporation and allow the Corporation, at the Corporation’s expense, to undertake appropriate action to prevent disclosure of the Information deemed confidential;

(x) use its best efforts to furnish, at the request of any Stockholder requesting Registration of Registrable Shares pursuant to this Section 6(a), on the date that such Registrable Shares are delivered to the underwriters for sale in connection with a Registration pursuant to this Section 6, if such Registrable Shares are sold through underwriters, or if such Registrable Shares are not being sold through underwriters, on the date that the Prospectus with respect to such Registrable Shares becomes effective:

(xii) issue to any underwriter to which the Stockholders holding such Registrable Shares may sell shares in such offering certificates evidencing such Registrable Shares;

(xiii) list such Registrable Shares on any national securities exchange on which any shares of the Common Stock are listed or, if the shares of Common Stock are not listed on a national securities exchange, use its best efforts to qualify such Registrable Shares for inclusion on the automated quotation system of the National Association of Securities Dealers, Inc. (the “NASD”), or such other national securities exchange as the holders of a majority of such Registrable Shares shall reasonably request;

(xiv) otherwise use its best efforts to comply with all applicable rules and regulations of the Commission and make available to its Stockholders, as soon as reasonably practicable, earnings statements (which need not be audited) covering a period of 12 months beginning within three months after the effective date of the Prospectus; and

(xv) subject to all the other provisions of this Agreement, use its best efforts to take all other steps necessary to effect the Registration of such Registrable Shares contemplated hereby.

(b) Each holder of the Registrable Shares, upon receipt of any notice from the Corporation of any event of the kind described in Section 6(a) hereof, shall forthwith discontinue Registration of the Registrable Shares pursuant to the Prospectus covering such Registrable Shares until such holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(a) hereof, and, if so directed by the Corporation, such holder shall deliver to the Corporation all copies, other than permanent file copies then in such holder’s possession, of the Prospectus covering such Registrable Shares at the time of receipt of such notice.

Section 7. Registration Expenses.

The Corporation will pay all Registration Expenses in connection with all Registrations under Section 2(a), Section 3 or Section 4, provided, however, that any of the expenses for any Registration or Prospectus requested by any Stockholder pursuant to this Agreement and subsequently withdrawn solely by the Stockholder, and not due to the exercise of the right of the Corporation pursuant to Section 2(c) hereunder, will be borne by the Stockholder (or if applicable, the Stockholders on a pro rata basis) unless the Stockholders holding at least a majority of the then outstanding Registrable Shares agree to forfeit their right to one Long-Form Registration pursuant to Section 2(b); provided, further that, if at the time of that withdrawal, the Stockholder has learned of a material adverse change in the condition or business of the Corporation from that known to the Stockholder at the time of its request for a Registration and has withdrawn such request with reasonable promptness following discovery by the Stockholder of that material adverse change, then such Stockholder will not be required to pay any of the Registration Expenses. For greater certainty, a withdrawal by a Stockholder caused by a material adverse change in the condition, business or prospect of the Corporation in respect of a Long-Form Registration, shall not apply to reduce the number of remaining Long-Form Registrations permitted under Section 2 (b). All Selling Expenses in connection with each Registration under Section 2(a), Section 3 or Section 4 will be borne by the participating Stockholders in proportion to the number of Registrable Shares sold by each Stockholder relative to the total number of Registrable Shares sold pursuant to the Registration. For greater certainty, the Corporation will pay as part of the Registration Expenses the fees and disbursements of one legal counsel chosen by the Stockholders participating in the Registration. The fees and disbursements of any other legal counsel retained individually by a Stockholder or a group of Stockholders shall be borne by such Stockholders, as the case may be.

Section 8. Rule 144 Reporting.

With a view to making available to each Stockholder the benefits of Rule 144 and any other rule or regulation of the Commission that may at any time permit a Stockholder to sell securities of the Corporation to the public without registration or pursuant to a Short-Form Registration, the Corporation agrees to :

(a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times after 90 days after the effective date of the Corporation’s Initial Registration so long as the Corporation remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act;

(b) file with the Commission in a timely manner all other reports and documents required of the Corporation under the Exchange Act at any time after it has become subject to such reporting requirements; and

(c) so long as a Stockholder owns any Registrable Shares, furnish to the Stockholder forthwith upon written request a written statement by the Corporation as to its compliance with the reporting requirements of Rule 144 (at any time from and after 90 days following the effective date of the Corporation’s Initial Registration provided the Corporation has become subject to such reporting requirements), and of the Securities Act and the Exchange Act (at any time after the Corporation has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Corporation, and such other reports and documents so filed or other information as such Stockholder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Stockholder to sell any such securities without registration.

Section 9. Canadian Securities Law Requirements.

With a view to making available the benefits of certain rules and regulations of any Canadian Securities Laws that may at any time permit the sale of the Registrable Shares to the public without the filing of a Prospectus, the Corporation agrees to use its best efforts to:

(a) once a public market exists in Canada for the shares of Common Stock, maintain a listing of the shares of Common Stock on each Canadian stock exchange or quotation system on which the shares of Common Stock were listed or quoted in connection with the Initial Registration or subsequent Registration;

(b) file with the appropriate Canadian Securities Laws regulatory authorities in a timely manner all reports and other documents required of the Corporation under Canadian Securities Laws (at any time after the date that the Corporation becomes a reporting issuer under Canadian Securities Laws); and

(c) subject to the terms of this Agreement, qualify the shares of Common Stock as freely tradeable under any Prospectus filed by the Corporation or through a prospectus exemption in accordance with applicable Canadian Securities Laws including in connection with the Initial Registration.

Section 10. Indemnification.

(a) The Corporation shall indemnify and hold harmless the holders of Registrable Shares, each underwriter, broker or any other person acting on behalf of such holders of Registrable Shares (including such holders’ directors, officers, employees, partners, members, shareholders, legal counsels and agents) and each

other person, if any, who controls any of the foregoing persons within the meaning of the Securities Act (the “Investor Indemnified Parties”), to the fullest extent permitted by law, from and against any losses, claims, damages or liabilities, joint or several (or actions in respect thereof), to which the Investor Indemnified Parties may be subject under any securities laws or otherwise, insofar as those losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Prospectus under which such Registrable Shares were registered under the Securities Act, any preliminary Prospectus or final Prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to the Registration of any Registrable Shares, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, or any violation by the Corporation of the Securities Act or state, any securities or blue sky laws applicable to the Corporation and relating to action or inaction required of the Corporation in connection with such registration or qualification under such state securities or blue sky laws; and shall reimburse such Investor Indemnified Parties for any reasonable legal or other expenses reasonably incurred by any of them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Corporation shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action (including any legal or other expenses incurred) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in said Prospectus, amendment, supplement or document incident to registration or qualification of any Registrable Shares in reliance upon and in conformity with written information furnished to the Corporation through an instrument duly executed by the holders of Registrable Shares or their counsel or underwriter specifically for use inclusion therein; provided further, however, that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any untrue statement, alleged untrue statement, omission or alleged omission made in any preliminary Prospectus but eliminated or remedied in the final Prospectus, such indemnity agreement shall not inure to the benefit of any Investor Indemnified Parties from whom the person asserting any loss, claim, damage, liability or expense purchased the Restricted Shares which are the subject thereof, if a copy of such final Prospectus had been made available to such person and such Investor Indemnified Parties within a reasonable period of time prior to the sale, and such final Prospectus was not delivered to such person with or prior to the written confirmation of the sale of such Registrable Shares to such person.

(b) In connection with any Registration of Registrable Shares under the Securities Act pursuant to this Agreement, each holder of Registrable Shares shall severally and not jointly indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 10(a)) the Corporation, each director of the Corporation, each officer of the Corporation who shall sign such registration statement, each underwriter, broker or any other person acting on behalf of the holders of Registrable Shares and each person who controls any of the foregoing

persons within the meaning of the Securities Act (the “Corporation Indemnified Parties”) against any losses, claims, damages or liabilities (or actions in respect thereof), to which any of the foregoing persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the registration statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, if such untrue statement, alleged untrue statement, omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Corporation or such underwriter through an instrument duly executed by the holders of Registrable Shares or their counsel specifically for inclusion in such registration statement, preliminary prospectus, final prospectus, amendment, supplement or document; provided, however, that the maximum amount of liability in respect of such indemnification shall be limited, in the case of each seller of Registrable Shares, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Shares effected pursuant to such Registration.

(c) Promptly after receipt by an Investor Indemnified Party or a Corporation Indemnified Party, an “Indemnified Party” of notice of the commencement of any action involving a claim referred to in the Section 10(a) and Section 10(b), such Indemnified Party will, if a claim in respect thereof may be made against an indemnifying party, give written notice to the latter of the commencement of such action. The failure of any Indemnified Party to notify an indemnifying party of any such action shall not (except to the extent such failure shall have an adverse effect on the indemnifying party) relieve the indemnifying party from any liability in respect of such action that it may have to such Indemnified Party on account of this Section 10. In case any such action is brought against an Indemnified Party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof; provided, however, that if any Indemnified Party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such Indemnified Party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity agreement provided in this Section 10, the indemnifying party shall not have the right to assume the defense of such action on behalf of such Indemnified Party (but shall have the right to participate therein with counsel

of its choice) and such indemnifying party shall reimburse such Indemnified Party and any person controlling such Indemnified Party for that portion of the fees and expenses of any counsel retained by the Indemnified Party which is reasonably related to the matters covered by the indemnity agreement provided in this Section 10. If the indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it will not be obligated to pay the fees and expenses of more than one counsel with respect to such claim.

(d) If the indemnification provided for in this Section 10 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amounts paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and equitable if contribution pursuant hereto were determined by pro rata allocation or by any other method or allocation which does not take account of the equitable considerations referred to herein; provided, however, that the maximum amount of liability in respect of indemnification under this paragraph shall be limited, in the case of each holder of Registrable Shares, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Shares effected pursuant to such registration. No person guilty of fraudulent misrepresentation shall be entitled to contribution from any person.

Section 11. Underwriting Agreement.

Notwithstanding the provisions of Section 5, Section 6, Section 7 and Section 10, to the extent that the Stockholders shall enter into an underwriting or similar agreement, which agreement contains provisions covering one or more issues addressed in such Sections, the provisions contained in such agreement addressing such issue or issues shall control.

The Stockholders shall furnish to the Corporation such written information regarding the Stockholders and the distribution proposed by any Stockholders as the Corporation may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement.

Section 14. Termination.

This Agreement shall terminate and be of no further force or effect on the first to occur of (i) five years after the date of Initial Registration; (ii) when there shall no longer be any Registrable Shares outstanding, or (iii) as to any Stockholder, when all of the Registrable Shares held by such Stockholder may be disposed of within any 90 day period under Rule 144 under the Securities Act.

Section 15. Benefits of Agreement; Third Party Beneficiary.

This Agreement shall bind and inure to the benefit of the Corporation, the Stockholders and subject to Section 16, the respective successors and assigns of the Corporation and the Stockholders.

SECOND AMENDMENT TO THIRD AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT

This Second Amendment to Third Amended and Restated Registration Rights Agreement (the “Amendment”) is entered into, as of December 31, 2007 by and among Nexsan Corporation, a Delaware corporation (the “Corporation”), and the stockholders of the Corporation who are a party hereto. Unless otherwise specifically defined herein, all capitalized terms used in this Amendment shall have the meaning ascribed thereto in the Registration Rights Agreement (as defined below).

WHEREAS, the Corporation, the Prior Stockholders, the Other Rights Holders, the Series A Investors and Series C Investors are parties to a certain Third Amended and Restated Registration Rights Agreement, dated as of March 29, 2007, as amended by the Amendment to the Third Amended and Restated Registration Rights Agreement, dated November 14, 2007 (the “Registration Rights Agreement”);

WHEREAS, the Corporation is planning an underwritten initial public offering of its Common Stock (the “Offering”) pursuant to a registration statement to be filed with the U.S. Securities and Exchange Commission;

WHEREAS, in connection with the Offering, and as an inducement for the Corporation and the representatives of the investment banks that are underwriting the Offering to continue their efforts in connection with the Offering, the stockholders of the Corporation are requested to amend the Registration Rights Agreement as provided herein; and

1. Amendments. The Registration Rights Agreement is hereby amended as follows:

(A) Section 3(a) of the Registration Rights Agreement is hereby amended by deleting this section in its entirety and inserting in lieu thereof the following:

(a) If, at any time after the date on which the Corporation has consummated an Initial Registration, the Corporation proposes for any reason to Register Primary Shares under the Securities Act and/or the Canadian Securities Laws, it shall give written notice to the Stockholders of its intention to so Register such Primary Shares at least thirty (30) days before the initial filing of the registration statement and, upon the written request, delivered to the Corporation within twenty (20) days after delivery of any such

notice by the Corporation, of the Stockholders to include in such Registration of Registrable Shares (which request shall specify the number of Registrable Shares proposed to be included in such Registration and shall state that such Stockholders desire to sell such Registrable Shares in the public securities markets), the Corporation shall use its best efforts to cause all such Registrable Shares to be included in such Registration on the same terms and conditions as the securities otherwise being sold in such Registration; provided, however, that if the managing underwriter, if any, advises the Corporation that the inclusion of all Registrable Shares requested to be included in such Registration would be materially detrimental to the successful marketing (including pricing) of the Primary Shares proposed to be included in such Registration, then the number of Primary Shares and Registrable Shares proposed to be included in such Registration shall be included in the following order:

(i) first, the Primary Shares; and

(B) Section 3(b) of the Registration Rights Agreement is hereby amended by deleting this section in its entirety and inserting in lieu thereof the following:

(C) Section 5 of the Registration Rights Agreement is hereby amended by adding the sentence set forth below to the end of Section 5:

Notwithstanding anything to the contrary stated in this Section 5, neither the Corporation or the underwriters shall be prohibited or restricted in any way from permitting certain shares of the Corporation held by one or more stockholders from being registered and sold in the Initial Registration, nor shall any of the obligations of any Series A Investor, Series C Investor or Prior Stockholder under this Section 5 be waived or terminated as a result of any shares held by one or more stockholders of the Corporation being registered and sold in the Initial Registration.

2. Effective Date. This Amendment shall become effective without any further action on the date on which the Corporation shall have received counterparts hereof duly executed by necessary parties as required under Section 19 of the Registration Rights Agreement.

3. Full Force and Effect. The parties agree that all terms of the Registration Rights Agreement not otherwise amended hereunder shall remain in full force and effect.

[The remainder of this page intentionally left blank]

IN WITNESS WHEREOF, the parties hereto have executed this Second Amendment to Third Amended and Restated Registration Rights Agreement as of the date and year first above written.
