     3. Required Registration.

          (a) At any time after the earlier of (i) the 181st day following the closing of Company’s initial public offering and (ii) May 8, 2010, Investors holding at least twenty-five percent (25%) in interest of the then outstanding Preferred Registrable Securities may request the Company to register under the Securities Act all or any portion of the shares of Registrable Securities held by such requesting holder or holders for sale in the manner specified in such notice, provided, however, that Investors holding less than the aforementioned twenty-five percent (25%) in interest may make such request for registration by the Company if the Registrable Securities for which registration is requested have a reasonably anticipated aggregate offering price to the public of at least $5,000,000.

Notwithstanding anything to the contrary contained herein, no request may be made under this Section 3 within 90 days after the effective date of any registration statement on Form S-1 filed by the Company.

          (b) Following receipt of any notice under this Section 3, the Company shall immediately notify all holders of Registrable Securities from whom notice has not been received and such holders shall then be entitled within 15 days thereafter to request the Company to include in the requested registration all or any portion of their shares of Registrable Securities. The Company shall use its best efforts to register under the Securities Act, for public sale in accordance with the method of disposition described in paragraph (a) above, the number of shares of Registrable Securities specified in such notice (and in all notices received by the Company from other holders of Registrable Securities within 15 days after the giving of such notice by the Company). The Company shall be obligated to register Registrable Securities pursuant to this Section 3 on two (2) occasions only (which limitation shall not restrict the number of demands for registration that are permitted pursuant to and subject to Section 5 hereof) and only when the Investors propose to register Registrable Securities that may not be immediately registered on Form S-3 pursuant to a request for registration made pursuant to

Section 5; provided, however, that such obligation shall be deemed satisfied only when a registration statement covering all shares of Registrable Securities specified in notices received as aforesaid for sale in accordance with the method of disposition specified by the requesting holders (other than any such shares excluded solely (i) due to a holder’s failure to provide the Seller Information (as defined in Section 6) in accordance with Section 6 hereof or (ii) in the case of an underwritten public offering, due to refusal of a holder to enter into the Underwriting Agreement (as defined in Section 6) in accordance with Section 6 hereof) shall have become effective or if such registration statement has been withdrawn prior to the consummation of the offering at the request of the holders of Registrable Securities (other than as a result of a Material Adverse Change of which the holders of Registrable Securities initiating such registration were not aware at the time of their request under this Section 3) and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto (not including shares eligible for sale pursuant to the underwriters’ over-allotment option).

          (c) The Company shall not be entitled to include in any registration statement referred to in this Section 3 shares of Common Stock to be sold by the Company for its own account. Except for registration statements on Form ▇-▇, ▇-▇ or any successor thereto, the Company will not file with the Commission any other registration statement with respect to its Common Stock, whether for its own account or that of other stockholders, from the date of receipt of a notice from requesting holders requesting sale pursuant to an underwritten offering pursuant to this Section 3 until the completion of the period of distribution of the registration contemplated thereby.

          (d) If in the opinion of the managing underwriter the inclusion of all of the Registrable Securities requested to be registered under this Section would adversely affect the marketing of such shares, Registrable Securities shall be excluded from such registration to the extent deemed advisable by the managing underwriter and shall be excluded in the following order:

               (i) first, the Common Registrable Securities, pro rata among the holders thereof based upon the number of Common Registrable Shares requested to be registered by each such holder; and

               (ii) second, the Preferred Registrable Securities, pro rata among the holders thereof based upon the number of Preferred Registrable Shares requested to be registered by each such holder.

          (e) Notwithstanding the foregoing, the Company shall not be obligated to effect, or to take any action to effect, any registration requested pursuant to this Section 3 if, within 30 days of the receipt of such request, the Company notifies the Investors requesting such registration, that the Company intends to file a registration statement for a Company-initiated registration within 90 days from that date such notice is provided.

     3.1 Canadian Prospectus Requirements. If the Company at any time proposes to make a public offering of its securities for its own account, it will be in the Company’s discretion as to whether any such public offering will be made in both the United States or Canada, or in

only one of the aforementioned jurisdictions; provided, however, that notwithstanding the foregoing:

          (a) unless the initial public offering of the Company’s securities already involves such a filing, the Company shall, if requested by the holders of at least twenty percent (20%) of the Registrable Securities held by Persons resident in Canada, concurrently file a prospectus in a jurisdiction specified in Appendix B of MI 45-102 promulgated under Canadian securities laws for the purposes of becoming a “reporting issuer” therein, and use its commercially reasonable efforts to obtain a receipt therefor; and

          (b) in the event that the escrow of any Registrable Securities is required under applicable Canadian securities laws in connection with the initial public offering of the Company’s securities and a choice of escrow regime or policy is available to the Company, the Company agrees that it will adopt such regime or policy as would be most beneficial to the holders of Registrable Securities, as determined by the holders holding at least sixty-seven percent (67%) in interest of the then outstanding Registrable Securities.

     The Company shall cease to be subject to the obligations in paragraph (a) above to file a prospectus in any jurisdiction of Canada for the purposes of becoming a reporting issuer if the Company demonstrates (i) with an opinion of counsel reasonably acceptable to the holders of at least sixty-seven percent (67%) of the then outstanding Registrable Securities held by residents of Canada that such holders are permitted to publicly sell their Registrable Securities on a stock exchange or market in the United States without a prospectus in Canada, or (ii) with an opinion of counsel reasonably acceptable to the holders of at least sixty-seven percent (67%) of the then outstanding Registrable Securities held by residents of Canada that such holders are permitted to publicly sell their Registrable Securities on a stock exchange or market in the United States in reliance on a prospectus exemption under applicable Canadian securities laws other than a private placement exemption.

     4. Incidental Registration. If the Company at any time (other than pursuant to Section 3 or Section 5) proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to a registration statement in connection with the Company’s initial public offering of Common Stock and registration statements on Forms ▇-▇, ▇-▇ or another form not available for registering the Registrable Securities for sale to the public), each such time it will give written notice to all holders of outstanding Registrable Securities of its intention so to do. Upon the written request of any such holder, received by the Company within 15 days after the giving of any such notice by the Company, to register any of its Registrable Securities, the Company will use its best efforts to cause the Registrable Securities as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Company, all to the extent required to permit the sale or other disposition by the holder of such Registrable Securities so registered. In the event that any registration pursuant to this Section 4 shall be, in whole or in part, an underwritten public offering of Common Stock, the number of shares of Registrable Securities to be included in such an underwriting may be reduced if in the opinion of the managing underwriter the inclusion of all of the Registrable Securities requested to be registered under this Section would adversely affect the marketing of such shares. In such case, shares to be excluded from such registration shall be

to the extent deemed advisable by the managing underwriter and shall be excluded in the following order:

          (a) first, the Common Registrable Securities and IBM Registrable Securities, pro rata among the holders thereof based upon the number of Common Registrable Shares and IBM Registrable Securities requested to be registered by each such holder;

          (b) second, the Preferred Registrable Securities, pro rata among the holders thereof based upon the number of Preferred Registrable Shares requested to be registered by each such holder; provided, that, in no event will less than thirty-five percent (35%) of the total number of shares of Common Stock be included in such underwriting; and

           (c) third, the securities to be registered for the Company’s own account.

     5. Registration on Form S-3. If at any time (i) holders of at least thirty percent (30%) of then outstanding Registrable Securities request that the Company file a registration statement on Form S-3 or any successor thereto for a public offering of all or any portion of the shares of Registrable Securities held by such requesting holders, and (ii) the Company is a registrant entitled to use Form S-3 or any successor thereto to register such shares, then the Company shall use its best efforts to register under the Securities Act on Form S-3 or any successor thereto, for public sale in accordance with the method of disposition specified in such notice, the number of shares of Registrable Securities specified in such notice; provided, however, that the Registrable Securities for which registration has been requested have a reasonably anticipated aggregate offering price to the public of at least $1,000,000. Whenever the Company is required by this Section 5 to use its best efforts to effect the registration of Registrable Securities, each of the procedures and requirements of Section 3 (including but not limited to the requirement that the Company notify all holders of Registrable Securities from whom notice has not been received and provide them with the opportunity to participate in the offering and the requirement that such request not be made within 90 days after the effective date of any registration statement on Form S-1 filed by the Company) shall apply to such registration, provided, however, that there shall be no limitation on the number of registrations on Form S-3 which may be requested and obtained under this Section 5, and provided, further, however, that the requirements contained in the first sentence of Section 3(a) shall not apply to any registration on Form S-3 which may be requested and obtained under this Section 5. Notwithstanding anything to the contrary in this Section 5, the Company shall not be required to effect more than two (2) registrations pursuant to this Section 5 in any 12 month period.

     5.1. Notwithstanding the obligations set forth in Section 3 and Section 5, if the Company furnishes to Investors requesting a registration pursuant to Section 3 or Section 5 a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board of Directors it would be materially detrimental to the Company and its stockholders for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (a) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the Company; (b) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; (c) render the Company unable to comply with requirements under the Securities Act or

Exchange Act or (d) result in the filing of, or continued effectiveness of, as applicable, a registration statement or prospectus, or any document incorporated or deemed to be incorporated therein by reference, which, in the case of a registration statement, would contain an untrue statement of a material fact or omit a material fact required to be stated therein or necessary to make the statements therein not misleading, or, in the case of the Prospectus, would 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, in the light of the circumstances under which they were made, not misleading, then the Company shall have the right to defer taking action with respect to registration request made pursuant Section 3 or Section 5 or may suspend an effective registration statement filed pursuant to this Agreement; provided, however, that the Company may not invoke this right for more than two periods not in excess of 90 days in the aggregate in any twelve (12) month period.

     6. Registration Procedures. If and whenever the Company is required by the provisions of Sections 3, 4 or 5 to use its best efforts to effect the registration of any shares of Registrable Securities under the Securities Act, the Company will, as expeditiously as possible:

          (a) prepare and file with the Commission a registration statement (which, in the case of an underwritten public offering pursuant to Section 3, shall be on Form S-1 or other form of general applicability satisfactory to the managing underwriter selected as therein provided) with respect to such securities and use its best efforts to cause such registration statement to become and remain effective for the period of the distribution contemplated thereby (determined as hereinafter provided);

          (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for the period specified in paragraph (a) above and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement in accordance with the sellers’ intended method of disposition set forth in such registration statement for such period;

          (c) furnish to each seller of Registrable Securities and to each underwriter such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such registration statement;

          (d) use its best efforts to register or qualify the Registrable Securities covered by such registration statement under the securities or “blue sky” laws of such jurisdictions as the sellers of Registrable Securities or, in the case of an underwritten public offering, the managing underwriter reasonably shall request, provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction;

          (e) use its best efforts to list the Registrable Securities covered by such registration statement with any securities exchange on which the Common Stock of the Company is then listed;

          (f) provide a transfer agent and registrar for all such Registrable Securities registered pursuant hereto and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration statement;

          (g) immediately notify each seller of Registrable Securities and each underwriter under such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, 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;

          (h) if the offering is underwritten and at the request of any seller of Registrable Securities, use its best efforts to furnish on the date that Registrable Securities are delivered to the underwriters for sale pursuant to such registration: (i) an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters and to such seller, stating that such registration statement has become effective under the Securities Act and that (A) to the best knowledge of such counsel, no stop order suspending the effectiveness thereof has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Securities Act, (B) the registration statement, the related prospectus and each amendment or supplement thereof comply as to form in all material respects with the requirements of the Securities Act (except that such counsel need not express any opinion as to financial statements contained therein) and (C) to such other effects as reasonably may be requested by counsel for the underwriters or by such seller or its counsel and (ii) a letter dated such date from the independent public accountants retained by the Company, addressed to the underwriters and to such seller, stating that they are independent public accountants within the meaning of the Securities Act and that, in the opinion of such accountants, the financial statements of the Company included in the registration statement or the prospectus, or any amendment or supplement thereof, comply as to form in all material respects with the applicable accounting requirements of the Securities Act, and such letter shall additionally cover such other financial matters (including information as to the period ending no more than five (5) business days prior to the date of such letter) with respect to such registration as such underwriters reasonably may request;

          (i) make available for inspection by each seller of Registrable Securities, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement. The rights granted pursuant to this subsection (i) may not be assigned or otherwise conveyed by such person or by any subsequent transferee of any such rights without the written consent of the Company, which consent shall not be unreasonably withheld; provided that the Company may

refuse such written consent if the proposed transferee is a competitor of the Company as determined by the Board of Directors; and provided further, that no such written consent shall be required if the transfer is made to a party who is not a competitor of the Company and who is a parent, subsidiary, affiliate, partner or group member of such person;

          (j) advise each selling holder of Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for such purpose and promptly use all reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

          (k) cooperate with the selling holders of Registrable Securities and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, such certificates to be in such denominations and registered in such names as such holders or the managing underwriters may request at least two (2) business days prior to any sale of Registrable Securities; and

          (l) permit any holder of Registrable Securities which holder, in the sole and exclusive judgment, exercised in good faith, of such holder, might be deemed to be a controlling person of the Company, to participate in good faith in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such holder and its counsel should be included, subject to review by the Company and its counsel after consultation with such holder.

     For purposes of Section 6(a) and 6(b) and of Section 3(c), the period of distribution of Registrable Securities in a firm commitment underwritten public offering shall be deemed to extend until each underwriter has completed the distribution of all securities purchased by it, and the period of distribution of Registrable Securities in any other registration shall be deemed to extend until the earlier of the sale of all Registrable Securities covered thereby and 180 days after the effective date thereof.

     In connection with each registration hereunder, the sellers of Registrable Securities will furnish to the Company in writing such information with respect to themselves and the proposed distribution by them as reasonably shall be necessary in order to assure compliance with federal and applicable provincial or state securities laws (the “Seller Information”).

     In connection with each registration pursuant to Sections 3, 4 or 5 covering an underwritten public offering, the Company and each seller agree to enter into a written agreement with the managing underwriter selected in the manner herein provided in such form and containing such provisions as are customary in the securities business for such an arrangement between such underwriter and companies of the Company’s size and investment stature (the “Underwriting Agreement”).

     7. Expenses. All expenses incurred by the Company in complying with Sections 3, 4 and 5, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel (including the reasonable fees and expenses of one counsel selected by the Investors participating in the applicable registration holding a majority of the Registrable

Securities being registered, which fees and expenses shall not exceed $30,000) and independent public accountants for the Company, fees and expenses (including counsel fees) incurred in connection with complying with state securities or “blue sky” laws, fees of the National Association of Securities Dealers, Inc., fees of transfer agents and registrars, costs of insurance, and fees and disbursements of one counsel for the sellers of Registrable Securities, but excluding any Selling Expenses, are called “Registration Expenses”. All underwriting discounts, selling commissions and transfer taxes applicable to the sale of Registrable Securities are called “Selling Expenses”.

     The Company will pay all Registration Expenses in connection with each registration statement under Sections 3, 4 or 5. All Selling Expenses in connection with each registration statement under Sections 3, 4 or 5 shall be borne by the participating sellers in proportion to the number of shares sold by each, or by such participating sellers other than the Company (except to the extent the Company shall be a seller) as they may agree.

     8. Indemnification and Contribution.

          (a) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Sections 3, 4 or 5, the Company will indemnify and hold harmless each seller of such Registrable Securities thereunder, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person 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 any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities were registered under the Securities Act pursuant to Sections 3, 4 or 5, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, 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, and will reimburse each such seller, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability (i) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by any such seller, any such underwriter or any such controlling person in writing specifically for use in such registration statement or prospectus or (ii) arises solely due to failure of such seller to deliver any amendment or supplement to such registration statement or prospectus which has previously been provided to such seller by the Company.

          (b) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Sections 3, 4 or 5, each seller of such Registrable Securities thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of the Securities Act, each officer of the Company who signs the registration statement, each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the Securities

Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or such officer, director, underwriter or controlling person 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 any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the Securities Act pursuant to Sections 3, 4 or 5, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, 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, and will reimburse the Company and each such officer, director, underwriter and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, provided, however, that such seller will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to the Company by such seller specifically for use in such registration statement or prospectus, and provided, further, however, that the liability of each seller hereunder shall be limited to the proportion of any such loss, claim, damage, liability or expense which is equal to the proportion that the public offering price of the shares sold by such seller under such registration statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the net proceeds received by such seller from the sale of Registrable Securities covered by such registration statement.

          (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 8 and shall only relieve it from any liability which it may have to such indemnified party under this Section 8 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof 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 and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred.

          (d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any holder of Registrable Securities exercising rights under this Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this Section 8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 8 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling holder or any such controlling person in circumstances for which indemnification is provided under this Section 8; then, and in each such case, the Company and such holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that such holder is responsible for the portion represented by the percentage that the public offering price of its Registrable Securities offered by the registration statement bears to the public offering price of all securities offered by such registration statement, and the Company is responsible for the remaining portion; provided, however, that, in any such case, (A) no such holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered by it pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

     9. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, at all times after 90 days after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, the Company agrees to:

          (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act;

          (b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

          (c) furnish to each holder of Registrable Securities forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of such Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as such holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such holder to sell any Registrable Securities without registration.

     10. Right of First Refusal

          (a) Right of First Refusal. The Company shall not issue, sell or exchange, agree or obligate itself to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange, any Equity Securities, unless the Company shall have first offered to sell such securities (the “Offered Securities”) to the Investors (each an “Offeree” and collectively, the

“Offerees”) as follows: Each Offeree shall have the right to purchase (x) that portion of the Offered Securities as the number of shares of Registrable Securities then held by such Offeree bears to total number of shares of Common Stock of the Company (including any shares of Preferred Stock or Exchangeable Shares, on an as-exchanged and as-converted to Common Stock basis) (the “Basic Amount”), and (y) such additional portion of the Offered Securities as such Offeree shall indicate it will purchase should the other Offerees subscribe for less than their Basic Amounts (the “Undersubscription Amount”), at a price and on such other terms as shall have been specified by the Company in writing delivered to such Offeree (the “Offer”), which Offer by its terms shall remain open and irrevocable for a period of 20 days from receipt of the Offer.

          (b) Notice of Acceptance. Notice of each Offeree’s intention to accept, in whole or in part, any Offer made pursuant to Section 10(a) shall be evidenced by a writing signed by such Offeree and delivered to the Company prior to the end of the 20-day period of such offer, setting forth such of the Offeree’s Basic Amount as such Offeree elects to purchase and, if such Offeree shall elect to purchase all of its Basic Amount, such Undersubscription Amount as such Offeree shall elect to purchase (the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Offerees are less than the total Offered Securities, then each Offeree who has set forth Undersubscription Amounts in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, all Undersubscription Amounts it has subscribed for; provided, however, that should the Undersubscription Amounts subscribed for exceed the difference between the aggregate Basic Amounts of all the Offerees and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), each Offeree who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Undersubscription Amount subscribed for by such Offeree bears to the total Undersubscription Amounts subscribed for by all Offerees, subject to rounding by the Company to the extent it reasonably deems necessary.

          (c) Conditions to Acceptances and Purchase.

               (i) Permitted Sales of Refused Securities. In the event that Notices of Acceptance are not given by the Offerees in respect of all the Offered Securities, the Company shall have 90 days from the expiration of the period set forth in Section 10(a) to close the sale of all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Offerees (the “Refused Securities”) to the Person or Persons specified in the Offer, but only for cash and otherwise in all respects upon terms and conditions, including, without limitation, unit price and interest rates, which are no more favorable, in the aggregate, to such other Person or Persons or less favorable to the Company than those set forth in the Offer.

               (ii) Reduction in Amount of Offered Securities. In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 10(c)(i) above), then each Offeree may, at its sole option and in its sole discretion, reduce the number of, or other units of the Offered Securities specified in its respective Notices of Acceptance to an amount which shall be not less than the amount of the Offered Securities which the Offeree elected to purchase pursuant to Section 10(b) multiplied by a fraction, (i) the numerator of which shall be the amount of Offered Securities which the Company actually proposes to sell, and (ii) the denominator of which shall be the

amount of all Offered Securities. In the event that any Offeree so elects to reduce the number or amount of Offered Securities specified in its respective Notices of Acceptance, the Company may not sell or otherwise dispose of more than the reduced amount of the Offered Securities until such securities have again been offered to the Offerees in accordance with Section 10(a).

               (iii) Closing. Upon the closing, which shall include full payment to the Company, of the sale to such other Person or Persons of all or less than all the Refused Securities, the Offerees shall purchase from the Company, and the Company shall sell to the Offerees, the number of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 10(c)(ii) if the Offerees have so elected, upon the terms and conditions specified in the Offer. The purchase by the Offerees of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Offerees of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Offerees and their respective counsel.

          (d) Further Sale. In each case, any Offered Securities not purchased by the Offerees or other Person or Persons in accordance with Section 10(c) may not be sold or otherwise disposed of until they are again offered to the Offerees under the procedures specified in Sections 10(a), 10(b) and 10(c).

          (e) Exception. The rights of the Investors under this Section 10 shall not apply to:

               (i) shares of Common Stock issued or issuable upon conversion of the Preferred Stock;

               (ii) shares of Special Common Voting Stock and Special A-1 Voting Stock;

               (iii) shares of Common Stock and Preferred Stock issued or issuable upon exchange of Exchangeable Shares of the Canadian Subsidiary;

               (iv) shares of Common Stock issued by reason of a dividend, stock split, split-up, subdivision, combination or other distribution on shares of Common Stock;

               (v) securities issued in connection with a bona fide business acquisition of the Company;

               (vi) securities issued or issuable pursuant to strategic transactions entered into for primarily non-equity financing purposes and approved by the Board of Directors (including a majority of the members of the Board of Directors elected solely by the holders of the Series A-1 Preferred and Special A-1 Voting Stock);

               (vii) securities issued or issuable pursuant to equipment lease financings or bank credit arrangements entered into for primarily non-equity financing purposes approved by the Board of Directors (including a majority of the members of the Board of Directors elected solely by the holders of the Series A-1 Preferred and Special A-1 Voting Stock); and

               (viii) Reserved Employee Shares.

          (f) Holders of Exchangeable Shares. If an Investor holding Exchangeable Shares (an “Exchangeable Holder”) exercises its right of first refusal pursuant to this Section 10, the Company and the Canadian Subsidiary shall, at the request of the Exchangeable Holder, use commercially reasonable efforts to structure the proposed offer of Equity Securities to the Exchangeable Holder as an offer of securities of the Canadian Subsidiary which are exchangeable into such offered securities (the “Alternative Securities”), and make appropriate provision (through special voting stock of the Company or otherwise) to provide for voting rights representing such Exchangeable Holder’s interest; provided, however, that, the Exchangeable Holders exercising their respective rights of first refusal pursuant to this Section 10 and requesting Alternative Securities pursuant to this Section 10(f) shall have agreed to purchase Equity Securities with an aggregate purchase price of at least $1,000,000 pursuant to this Section 10.

          (g) Termination. The rights of the Offerees under this Section 10 shall terminate immediately prior to, but subject to the consummation of: (i) a Qualified Public Offering; (ii) the sale of all or substantially all of the assets of the Company; or (iii) the merger or consolidation (or equivalent transaction in any foreign jurisdiction) of the Company or any Subsidiary with or into, any other entity or entities (except a merger in which the Company is the surviving Corporation and the holders of the Company’s voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction or a consolidation or merger of a Subsidiary, the result of which is that the Company, directly or indirectly, owns all of the issued and outstanding capital stock, and any rights to acquire capital stock of the surviving Corporation immediately following the transaction)

     11. [Reserved]

     12. Covenants of the Company.

          (a) Affirmative Covenants of the Company Other Than Reporting Requirements. Without limiting any other covenants and provisions hereof, and except to the extent the following covenants and provisions of this Section 12(a) are waived in any instance by the holders of a majority in interest of the holders of Registrable Securities, the Company covenants and agrees that until the consummation of a Qualified Public Offering it will perform and observe the following covenants and provisions, and will cause each Subsidiary, if and when such Subsidiary exists, to perform and observe such of the following covenants and provisions as are applicable to such Subsidiary:

               (i) Payment of Taxes and Trade Debt. Pay and discharge, and cause each Subsidiary to pay and discharge, all taxes, assessments and governmental charges or levies imposed upon it or upon its income, profits or business, or upon any properties belonging to it, prior to the date on which penalties attach thereto, and all lawful claims which, if unpaid, might become a lien or charge upon any properties of the Company or any Subsidiary; provided, however, that neither the Company nor any Subsidiary shall be required to pay any such tax, assessment, charge, levy or claim which is being contested in good faith and by appropriate

proceedings if the Company or any Subsidiary shall have set aside on its books sufficient reserves, if any, with respect thereto. Pay and cause each Subsidiary to pay, when due, or in conformity with customary trade terms, all lease obligations, all trade debt, and all other Indebtedness incident to the operations of the Company or its Subsidiaries, except such as are being contested in good faith and by proper proceedings if the Company or Subsidiary concerned shall have set aside on its books sufficient reserves, if any, with respect thereto.

               (ii) Maintenance of Insurance. Use its best efforts to maintain from a responsible and reputable insurance company or association a Directors and Officers insurance policy in an aggregate amount of at least $5,000,000. Maintain, and cause each Subsidiary to maintain, insurance with responsible and reputable insurance companies or associations in such amounts and covering such risks as is customarily carried by companies engaged in similar businesses and owning similar properties in the same general areas in which the Company or such Subsidiary operates, but in any event in amounts sufficient to prevent the Company or Subsidiary from becoming a co-insurer. The Company will continue to include Toronto Dominion Investments, Inc. and The VenGrowth Investment Fund Inc. as notice parties to such policy and will request that the issuer(s) of such policy provide such designees with at least ten (10) days’ notice before such policy is terminated (for failure to pay premiums or otherwise) or assigned, or before any change is made in the designation of the beneficiary thereof.

               (iii) Preservation of Corporate Existence. Preserve and maintain, and, unless the Company deems it not to be in its best interests, cause each Subsidiary to preserve and maintain, its corporate existence, rights, franchises and privileges in the jurisdiction of its incorporation, and qualify and remain qualified, and cause each Subsidiary to qualify and remain qualified, as a foreign corporation in each jurisdiction in which such qualification is necessary or desirable in view of its business and operations or the ownership or lease of its properties. Secure, preserve and maintain, and cause each Subsidiary to secure, preserve and maintain, all licenses and other rights to use Intellectual Property Rights owned or possessed by it and deemed by the Company to be necessary to the conduct of its business and the businesses of its Subsidiaries, taken as a whole.

               (iv) Compliance with Laws. Comply, and cause each Subsidiary to comply, with the requirements of all applicable laws, rules, regulations and orders of any governmental authority, where noncompliance would have a material adverse effect on the Company or any Subsidiary or their business operations, prospects or condition (financial or otherwise).

               (v) Inspection. Permit, upon reasonable request and notice, each of the Investors holding at least 3,333,333 Shares (on an as-exchanged and as-converted basis, and as adjusted for any stock splits, stock dividends, combinations, reclassifications, recapitalizations or similar events occurring after the date of this Agreement) or any agents or representatives • thereof, to examine and make copies of and extracts from the books of account of, and visit and inspect the properties of the Company and any Subsidiary, to discuss the affairs, finances and accounts of the Company and any Subsidiary with any of its officers, directors or employees and independent accountants, and consult with and advise the management of the Company and any Subsidiary as to their affairs, finances and accounts, all at reasonable times during normal business hours. Subject to the disclosure of information of a non-technical nature, including

financial information, which such Investor discloses to its partners and/or shareholders generally, each such Investor agrees that it will keep confidential and will not disclose or divulge any confidential, proprietary or secret information which such Investor may obtain from the Company pursuant to financial statements, reports and other materials submitted by the Company as required hereunder, or pursuant to visitation or inspection rights granted hereunder unless such information is or becomes known to such Investor from a source other than the Company or is or becomes publicly known, or unless the Company gives its written consent to such Investor’s release of such information, except that no such written consent shall be required (and such Investor shall be free to release such information to such recipient) if such information is to be provided to such Investor’s counsel or accountant, or to an officer, director or partner of such Investor, provided that such Investor shall inform the recipient of the confidential nature of such information, and shall instruct the recipient to treat the information as confidential.

          (vi) Keeping of Records and Books of Account. Keep, and cause each Subsidiary to keep, adequate records and books of account in which complete entries will be made in accordance with United States generally accepted accounting principles consistently applied, reflecting all financial transactions of the Company and any Subsidiary, and in which, for each fiscal year, all proper reserves for depreciation, depletion, returns of merchandise, obsolescence, amortization, taxes, bad debts and other purposes in connection with its business shall be made.

          (vii) Maintenance of Properties. Maintain and preserve, and cause each Subsidiary to maintain and preserve, all of its properties and assets, necessary for the proper conduct of its business, in good repair, working order and condition, ordinary wear and tear excepted.

          (viii) Financings. Inform the Board of Directors of any negotiations, offers or contracts relating to possible financings of any nature for the Company, whether initiated by the. Company or any other Person, except for (A) arrangements with trade creditors, and (B) utilization by the Company or any Subsidiary of commercial lending arrangements with financial institutions.

          (ix) By-laws.. At all times, cause the bylaws of the Company to provide that, unless otherwise required by the laws of the State of Delaware, (i) any two directors and (ii) any holder or holders of at least twenty-five (25%) of the outstanding Registrable Securities, shall have the right to call a meeting of the Board of Directors or stockholders. At all times maintain provisions in the bylaws or certificate of incorporation of the Company indemnifying all directors against liability to the maximum extent permitted under the laws of State of Delaware. Cause each of its directors and officers, and each director and officer elected or appointed following the date hereof, to read the bylaws of the Company.

               (iii) Annual Reports: as soon as available and in any event within 90 days after the end of each fiscal year of the Company, a copy of the annual audited financial statements for such year for the Company and its Subsidiaries, including therein consolidated balance sheets of the Company and its Subsidiaries as of the end of such fiscal year and consolidated statements of operations and cash flow of the Company and its Subsidiaries for such fiscal year, setting forth in each case in comparative form the corresponding figures for the preceding fiscal year, all such consolidated statements to be duly certified by the chief financial officer of the Company and by such independent public accountants of recognized national standing approved by a majority of the Board of Directors; provided, however, that any information related to SR&ED tax credits may be furnished as soon as available and in any event within 120 days after the end of each fiscal year;

          (d) Observer Rights.

               (i) Until the consummation of a Qualified Public Offering, the Company shall invite representatives with relevant knowledge of the Company’s industry (each, a “Representative”) sponsored by (i) if at any time Samsung does not have the right to designate a member of the Board of Directors pursuant to Section 6 of the Company’s Amended and Restated Stockholders. Agreement (the “Stockholders Agreement”), dated as of the date hereof, Samsung, (ii) if at any time 3i Technology Partners L.P. (“3i”) does not have the right to designate a member of the Board of Directors pursuant to Section 6 of the Stockholders Agreement, 3i, and (iii) if at any time The VenGrowth Investment Fund Inc. and The VenGrowth II Investment Fund Inc. (together, “VenGrowth”) do not have the right to designate a member of the Board of Directors pursuant to Section 6 of the Stockholders Agreement, VenGrowth, in each case to attend at the expense of the respective sponsoring party in a

nonvoting observer capacity all meetings of the Board of Directors and, in this respect, shall give each Representative copies of all notices, minutes, consents, and other material that it provides to its directors (subject to the limitations and exceptions in this Section 12(d)). Each Representative shall be subject to the approval of the Board of Directors in its good faith judgment. No Representative will have the right to attend any meetings of the committees of the Board of Directors.

                 (ii) The Company reserves the right to exclude any Representative from access to any material or meeting or portion thereof if the Company believes that such exclusion is reasonably necessary to preserve the attorney-client privilege, fulfill the Company’s obligations with respect to confidential or proprietary or similar confidential information of third parties, or preserve the integrity of the Company’s trade secrets, or protect similar proprietary information.

                 (iii) Each Representative shall immediately report to the Board of Directors if he or she becomes aware of the existence of conflict of interest of such Representative or the business organization affiliated with such Representative (for the purpose of such determination, it shall be assumed that the Representative is in a fiduciary relationship with the Company). In the event that a majority of the Board, acting reasonably and in good faith (and after deliberation in a closed session in which they can exclude the applicable Representative), determines that the presence of the Representative at portions of a Board meeting would result in an actual or potential conflict of interest, inhibit deliberations by the Board on a material matter or could otherwise be injurious to the Company, the Company shall have the right to exclude the Representative from portions of any meetings of the Board dealing with such matter and to omit to provide the Representative with certain information if such information involves information or analysis dealing with such matter.

                 (iv) Samsung, 3i and VenGrowth each covenants and agrees that all of the information disclosed to its Representative pursuant to the provisions of this Section 12(d) shall be treated in accordance with Section 12(a)(v) of this Agreement. Each person who is sponsored as a Representative, shall agree to treat information disclosed to him or here in accordance with Section 12(a)(v) of this Agreement and to otherwise comply with the requirements of this Section 12(d).

                 (v) Notwithstanding the foregoing, in the event any of Samsung, VenGrowth or 3i for any reason ceases to hold Shares representing a value of at least $1,250,000 calculated based on the original cost of such capital stock, then such party shall no longer be entitled to sponsor an observer as specified above.

          (e) Notice of Certain Transactions. Samsung shall be entitled to notice in the event that the Company receives a bona fide offer to be acquired by means of (i) a merger, consolidation or other business combination pursuant to which the stockholders of the Company immediately prior to the effective time of such transaction have beneficial ownership of less than a majority of the total combined voting power with respect to the election of directors of the surviving entity (and the entity that controls such surviving entity) immediately following such transaction, or (ii) the sale, lease or other disposition of all or substantially all of the assets of the Company, within ten (10) business days after receipt of a proposal for any such transaction. The

Company shall provide Samsung only with written notice that an offer has been received and shall not be required to disclose the name of the proposed acquirer or any summary of the terms of the proposed transaction. Samsung agrees that information disclosed to it pursuant to the provisions of this Section 12(e) shall be treated in accordance with Section 12(a)(v) of this Agreement.

     13. Representations and Warranties of the Company and the Canadian Subsidiary. The Company and the Canadian Subsidiary represent and warrant as follows:

               (b) If the Company believes public disclosure of Samsung’s relationship with the Company is required by law, it shall no less than five (5) days prior to the filing of such public disclosure (including, without limitation, filing any document or material with the Commission, or any other competent regulatory authority, which contains a reference to Samsung) provide Samsung with notice of and a copy of such disclosure, and revise such disclosure as reasonably requested by Samsung within two (2) days following the delivery of such information to Samsung, and if available, seek confidential treatment for such portions of such disclosure as may be reasonably requested by Samsung.

          (b) Successors and Assigns; Certain Transfers. All covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto (including without limitation permitted transferees of any Registrable Securities), whether so expressed or not, provided, however, that registration rights conferred herein on the Investors shall only inure to the benefit of a transferee of Registrable Securities if (i) there is transferred to such transferee at least 1,666,667 shares of Registrable Securities (subject to equitable adjustment in the event of any stock splits, stock dividends, combinations, reclassifications, recapitalizations or other similar events occurring after the date of this Agreement) or (ii) such transferee is, in the case of a transfer by a partnership, a partner or retired partner, in the case of a transfer by a limited liability company, a member or former member, or in any other case, a shareholder or affiliate, of a party hereto; and provided further, however, that in all cases such transferees agree in writing to be bound by the terms hereof to the same extent as if such transferees were Investors hereunder.

This Agreement shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts, without regard to its principles of conflicts of laws.

          (e) Waiver; Amendment.

               (i) Any of the rights of holders of Registrable Securities pursuant to this Agreement may be waived by an instrument in writing executed and delivered by the holders of a majority in interest of the Preferred Registrable Securities; provided, however, that any rights of any Regulated Fund pursuant to Section 10(f) hereof may not be waived without the written consent of such Regulated Fund. Any waiver effected in accordance with this paragraph shall be binding on all holders of Registrable Securities. Any waiver by any party of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach of that provision or of any other provision hereof.

               (ii) This Agreement may not be amended or modified, and except as provided in subsection (e)(i) above, no provision hereof may be waived, without the written consent of the Company and the holders of a majority in interest of the Preferred Registrable Securities. Notwithstanding the foregoing, (A) no amendment to Section 10(f) hereof which adversely affects a Regulated Fund’s rights thereunder shall be effective without the written consent of such Regulated Fund, and (B) no amendment to this Agreement that materially and adversely affects Investors holding Exchangeable Shares in a manner different than the Investors holding shares of capital stock of the Company shall be effective without the written consent of a majority in interest of the Investors holding Exchangeable Shares. Additional purchasers of Series A-1 Preferred or Class A-1 Exchangeable Shares pursuant to the Purchase Agreement who are not already parties to this Agreement may become parties to this Agreement without further action or consent by any party thereto, by executing and delivering to the Company an Instrument of Accession. Such additional purchasers shall thereafter be “Investors” for purposes of this Agreement and Schedule A shall be updated accordingly.

          (g) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

          (h) Termination of Registration Obligations. The obligations of the Company to register shares of Registrable Securities under Sections 3, 4 or 5 shall terminate on the earlier of: (i) the fifth anniversary of the date of a Qualified Public Offering or (ii) with respect to any particular shares of Registrable Securities, the date on which such Registrable Securities are eligible for resale pursuant to Rule 144(k) promulgated under the Securities Act.

          (i) Lock-up. If requested in writing by the underwriters for the initial underwritten public offering of securities of the Company, each holder of Registrable Securities who is a party to this Agreement hereby agrees in connection with such initial public offering, not to sell publicly any shares of Registrable Securities or any other shares of Common Stock (other than shares of Registrable Securities or other shares of Common Stock being registered in such offering), without the consent of the managing underwriter for a period not to exceed 180 days following the effective date of the registration statement relating to such offering and, at such underwriter’s request, shall sign a lock-up agreement to such effect; provided, however, that all persons entitled to registration rights with respect to shares of Common Stock who are not parties to this Agreement, all other persons selling shares of Common Stock in such offering, all persons holding in excess of five percent (5%) of the capital stock of the Company on a fully

diluted basis and all executive officers and directors of the Company shall also have agreed not to sell publicly any Registrable Securities or other shares of Common Stock under the circumstances and pursuant to the terms set forth in this Section 16(i); and provided, further, however, that any such lock-up agreement shall provide that if the managing underwriter releases any shares from the lock-up with respect to such offering (other than discretionary releases due to financial hardship with respect to such number of shares as does not exceed an aggregate of $50,000 in value for any holder) prior to the scheduled expiration date, the managing underwriter shall contemporaneously release a pro rata portion of the Registrable Securities held by all other persons subject to such lock-up. Notwithstanding the foregoing, if: (x) during the last 17 days of the 180-day lock-up period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (y) prior to the expiration of the 180-day lock-up period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 180-day lock-up period, the restrictions described above shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

          (j) Subsequent Grants of Registration Rights. Except to the extent that additional purchasers of Series A-1 Preferred and Class A-1 Exchangeable Shares are permitted to become parties to this agreement after the date hereof, the Company shall not grant to any third party any registration rights more favorable than or inconsistent with any of those contained herein, so long as any of the registration rights under this Agreement remains in effect.

          (k) Severability. If any provision of this Agreement shall be held to be illegal, invalid or unenforceable, such illegality, invalidity or unenforceability shall attach only to such provision and shall not in any manner affect or render illegal, invalid or unenforceable any other provision of this Agreement, and this Agreement shall be carried out as if any such illegal, invalid or unenforceable provision were not contained herein.

          (l) Entire Agreement. This Agreement amends, restates and supersedes the Prior Agreement in its entirety and the Company and the Investors representing the holders of a majority in interest of the Registrable Securities hereby consent to such amendment and restatement.

Exhibit A

Notice Regarding European Directive on Data Protection

     This Notice of Article VIII of the By-Laws of SiGe Semiconductor, Inc. (the “Company”) is being delivered to you pursuant to Section 12(a)(xviii) of that certain Amended and Restated Investor Rights Agreement, dated May 8, 2007 (the “Rights Agreement”) by and among the Company, the Canadian Subsidiary and the Investors (as defined in the Rights Agreement).

     3i Group plc, a holding company of one of the holders of the Company’s Preferred Stock (the “3i Entity”), is incorporated in Europe and is subject to a European Directive on data protection (as enshrined by UK Act of Parliament in The Data Protection Act of 1998) (the “Directive”). The primary effect of the Directive is to prohibit the processing of personal data without notification and consent. Because it is possible that the 3i Entities may be deemed to have processed personal data within the meaning of the Directive in connection with their investments in portfolio companies, the 3i Entity requires each of their portfolio companies to insert certain standard language regarding the Directive into such portfolio company’s certificate of incorporation or bylaws. The language regarding the Directive contained in the Company’s Certificate of Incorporation is set forth below:

For the purposes of all applicable legislation and regulation, each of the stockholders, officers and directors of SiGe Semiconductor, Inc. authorize 3i Technology II Partners LP, 3i Group plc and affiliates of 3i Group plc (both within and outside the United States) (“3i Group”) to process (but only amongst the 3i Group and its advisers and only within the meaning of European Directive 95/46/EC) any data or information concerning them which is obtained in the course of its and their due diligence and other investment business. The data and information which may be processed for such purposes shall include any information which may have a bearing on the prudence or commercial merits of investing, or disposing of any stock (or other investment or security) in the Company. Nothing in this authority shall entitle any 3i Group entity to make any disclosure of such data or information for third parties.
