2.  DEMAND REGISTRATIONS.

(a)  Right to Request Registration.  At any time 180 days following the IPO, any Holder or Holders may request registration under the Securities Act (“Initiating Holders”) of all or part of the Registrable Common Shares (“Demand Registration”); provided, that (i) any time such Holder Demand Registration must cover an amount of Registrable Common Shares held by such Holder that is greater than or equal to 5% of the Company’s outstanding common shares.

Within 10 days after receipt of any such request for Demand Registration, the Company shall give written notice of such request to all other Holders of Registrable Common Shares and shall, subject to the provisions of Section 2(d) hereof, include in such registration all such Registrable Common Shares with respect to which the Company has received written requests for inclusion therein within 15 days after the receipt of the Company’s notice.

(b)  Number of Demand Registrations.  Subject to the provisions of Section 2(a), the Initiating Holders of Registrable Common Shares shall collectively be entitled to request an aggregate of three (3) Demand Registrations.  A registration shall not count as one of the permitted Demand Registrations (i) until it has become effective, (ii) if the Initiating Holders requesting such registration are not able to register at least 50% of the Registrable Common Shares requested by such Initiating Holder to be included in such registration or (iii) in the case of a Demand Registration that would be the last permitted Demand Registration requested hereunder, if the Initiating Holder requesting such registration is not able to register all of the Registrable Common Shares requested to be included by such Initiating Holder in such registration.

(c)  Priority on Demand Registrations.  Except as provided in Section 2(g), the Company shall not include in any Demand Registration any securities which are not Registrable Common Shares without the written consent of the Holders of a majority of the shares of Registrable Common Shares to be included in such registration, or, if such Demand Registration is an underwritten offering, without the written consent of the managing underwriters.  If the managing underwriters of the requested Demand Registration advise the Company in writing that in their opinion the number of shares of Registrable Common Shares proposed to be included in any such registration exceeds the number of securities which can be sold in such offering and/or that the number of shares

3

of Registrable Common Shares proposed to be included in any such registration would adversely affect the price per share of the Company’s equity securities to be sold in such offering, the Company shall include in such registration only the number of shares of Registrable Common Shares which in the opinion of such managing underwriters can be sold.  If the number of shares which can be sold is less than the number of shares of Registrable Common Shares proposed to be registered, the amount of Registrable Common Shares to be so sold shall be allocated pro rata among the Holders of Registrable Common Shares desiring to participate in such registration on the basis of the amount of such Registrable Common Shares initially proposed to be registered by such Holders.  If the number of shares which can be sold exceeds the number of shares of Registrable Common Shares proposed to be sold, such excess shall be allocated pro rata among the other holders of securities, if any, desiring to participate in such registration based on the amount of such securities initially requested to be registered by such holders or as such holders may otherwise agree.

(d)  Restrictions on Demand Registrations.  The Company shall not be obligated to effect any Demand Registration within three months after the effective date of a previous Demand Registration, or a previous registration under which the Initiating Holders had piggyback rights pursuant to Section 3 hereof wherein the Initiating Holders were permitted to register, and actually sold, at least 50% of the shares of Registrable Common Shares requested to be included therein.  The Company may postpone for up to ninety (90) days the filing or the effectiveness of a Registration Statement for a Demand Registration if, based on the good faith judgment of the Company’s board of directors, such postponement or withdrawal is necessary in order to avoid premature disclosure of a matter the board has determined would not be in the best interest of the Company to be disclosed at such time; provided, however, that in no event shall the Company withdraw a Registration Statement after such Registration Statement has been declared effective; and provided, further, however, that in the event described above, the Initiating Holders requesting such Demand Registration shall be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations.  The Company shall provide written notice to the Initiating Holders requesting such Demand Registration of (x) any postponement or withdrawal of the filing or effectiveness of a Registration Statement pursuant to this Section 2(d), (y) the Company’s decision to file or seek effectiveness of such Registration Statement following such withdrawal or postponement and (z) the effectiveness of such Registration Statement.  The Company may defer the filing of a particular Registration Statement pursuant to this Section 2(d) only once during any twelve-month period.

(e)  Selection of Underwriters.  If any of the Registrable Common Shares covered by a Demand Registration are to be sold in an underwritten offering, the Initiating Holders shall have the right to select the managing underwriter(s) to administer the offering subject to the approval of the Company, which will not be unreasonably withheld.

(f)  Other Registration Rights.  The Company shall not grant to any Person the right, other than as set forth herein, to request the Company to register any securities of the Company except such rights as are not more favorable than or inconsistent with the

4

rights granted to the Holders herein.  In the event the Company grants rights which are more favorable, the Company will make such provisions available to the Holders and will enter into any amendments necessary to confer such rights on the Holders.

(g)  Effective Period of Demand Registrations.  After any Demand Registration filed pursuant to this Agreement has become effective, the Company shall use its best efforts to keep such Demand Registration effective for a period equal to 180 days from the date on which the SEC declares such Demand Registration effective (or if such Demand Registration is not effective during any period within such 180 days, such 180-day period shall be extended by the number of days during such period when such Demand Registration is not effective), or such shorter period which shall terminate when all of the Registrable Common Shares covered by such Demand Registration have been sold pursuant to such Demand Registration.  If the Company shall withdraw any Demand Registration pursuant to Section 2(d) (a “Withdrawn Demand Registration”), the Initiating Holders of the Registrable Common Shares remaining unsold and originally covered by such Withdrawn Demand Registration shall be entitled to a replacement Demand Registration which (subject to the provisions of this Section 2) the Company shall use its best efforts to keep effective for a period commencing on the effective date of such Demand Registration and ending on the earlier to occur of the date (i) which is 180 days from the effective date of such Demand Registration and (ii) on which all of the Registrable Common Shares covered by such Demand Registration have been sold.  Such additional Demand Registration otherwise shall be subject to all of the provisions of this Agreement.

3.  PIGGYBACK REGISTRATIONS.

(a)  Right to Piggyback.  If at any time following the IPO the Company proposes to register any of its common equity securities under the Securities Act (other than a registration statement on Form S-8 or on Form F-4 or any similar successor forms thereto), whether for its own account or for the account of one or more shareholders of the Company, and the registration form to be used may be used for any registration of Registrable Common Shares (a “Piggyback Registration”), the Company shall give prompt written notice (in any event within 10 days after its receipt of notice of any exercise of other demand registration rights) to all Holders of its intention to effect such a registration and, subject to Sections 3(b) and 3(c), shall include in such registration all Registrable Common Shares with respect to which the Company has received written requests for inclusion therein within 15 days after the receipt of the Company’s notice.  The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion.

(b)  Priority on Primary Registrations.  If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering and/or that the number of shares of Registrable Common Shares proposed to be included in any such registration would adversely affect the price per share of the Company’s equity securities to be sold in such offering, the Company shall include in

5

such registration (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Common Shares requested to be included therein by the Holders, pro rata among the Holders of such Registrable Common Shares on the basis of the number of shares requested to be registered by such Holders, and (iii) third, other securities requested to be included in such registration pro rata among the holders of such securities on the basis of the number of shares requested to be registered by such holders or as such holders may otherwise agree.

(c)  Priority on Secondary Registrations.  If a Piggyback Registration is an underwritten secondary registration on behalf of a holder of the Company’s securities other than Registrable Common Shares, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering and/or that the number of shares of Registrable Common Shares proposed to be included in any such registration would adversely affect the price per share of the Company’s equity securities to be sold in such offering, the Company shall include in such registration (i) first the securities requested to be included therein by the holders requesting such registration and the Registrable Common Shares requested to be included in such registration, pro rata among the holders of such securities on the basis of the number of shares requested to be registered by such holders, and (ii) second, other securities requested to be included in such registration pro rata among the holders of such securities on the basis of the number of shares requested to be registered by such holders or as such holders may otherwise agree.

(d)  Selection of Underwriters.  If any Piggyback Registration is an underwritten primary offering, the Company shall have the right to select the managing underwriter or underwriters to administer any such offering.

(e)  Other Registrations.  If the Company has previously filed a Registration Statement with respect to Registrable Common Shares, and if such previous registration has not been withdrawn or abandoned, the Company shall not be obligated to cause to become effective any other registration of any of its securities under the Securities Act, whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least three months has elapsed from the effective date of such previous registration.

4.  HOLDBACK AGREEMENTS.

(a)  The Company agrees not to effect any sale or distribution of any of its equity securities during the 10 days prior to and during the 180 days beginning on the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration (except as part of such underwritten registration or pursuant to registrations on Form S-8 or F-4 or any successor forms thereto) unless the underwriters managing the offering otherwise agree to a shorter period.

5.  REGISTRATION PROCEDURES.

(a)  Whenever the Holders request that any Registrable Common Shares be registered pursuant to this Agreement, the Company shall use its best efforts to effect the registration and the sale of such Registrable Common Shares in accordance with the intended methods of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

(i)  prepare and file with the SEC a Registration Statement with respect to such Registrable Common Shares and use its best efforts to cause such Registration Statement to become effective as soon as practicable thereafter; and before filing a Registration Statement or Prospectus or any amendments or supplements thereto, furnish to the Holders of Registrable Common Shares covered by such Registration Statement and the underwriter or underwriters, if any, copies of all such documents proposed to be filed, including documents incorporated by reference in the Prospectus and, if requested by such Holders, the exhibits incorporated by reference, and such Holders shall have the opportunity to object to any information pertaining to such Holders that is contained therein and the Company will make the corrections reasonably requested by such Holders with respect to such information prior to filing any Registration Statement or amendment thereto or any Prospectus or any supplement thereto;

(ii)  prepare and file with the SEC 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 a period of not less than 180 days, in the case of a Demand Registration or such shorter period as is necessary to complete the distribution of the securities covered by such Registration Statement and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement;

(iii)  furnish to each seller of Registrable Common Shares such number of copies of such Registration Statement, each amendment and supplement thereto, the Prospectus included in such Registration Statement (including each preliminary Prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Common Shares owned by such seller;

(iv)  use its best efforts to register or qualify such Registrable Common Shares under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Common Shares owned by such seller (provided, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph (d), (ii) subject itself to taxation in

7

any such jurisdiction or (iii) consent to general service of process in any such jurisdiction);

(v)  notify each seller of such Registrable Common Shares, at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, of the occurrence of any event as a result of which the Prospectus included in such Registration Statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, at the request of any such seller, the Company shall prepare a supplement or amendment to such Prospectus so that, as thereafter delivered to the purchasers of such Registrable Common Shares, such Prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading;

(vi)  in the case of an underwritten offering, enter into such customary agreements (including underwriting agreements in customary form with customary indemnification provisions) and take all such other actions as the Holders of a majority of the Registrable Common Shares being sold or the underwriters reasonably request in order to expedite or facilitate the disposition of such Registrable Common Shares (including, without limitation, making members of senior management of the Company available to participate in, and cause them to cooperate with the underwriters in connection with, “road-show” and other customary marketing activities (including one-on-one meetings with prospective purchasers of the Registrable Common Shares)) and cause to be delivered to the underwriters and the sellers, if any, opinions of counsel to the Company in customary form, covering such matters as are customarily covered by opinions for an underwritten public offering as the underwriters may request and addressed to the underwriters and the sellers;

(vii)  make available, for inspection by any seller of Registrable Common Shares, any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement;

(viii)  use its best efforts to cause all such Registrable Common Shares to be listed on each securities exchange on which securities of the same class issued by the Company are then listed;

(ix)  if requested, cause to be delivered, immediately prior to the effectiveness of the Registration Statement (and, in the case of an underwritten offering, at the time of delivery of any Registrable Common Shares sold pursuant thereto), letters from the Company’s independent certified public accountants addressed to each selling Holder (unless such selling Holder does not provide to

8

such accountants the appropriate representation letter required by rules governing the accounting profession) and each underwriter, if any, stating that such accountants are independent public accountants within the meaning of the Securities Act and the applicable rules and regulations adopted by the SEC thereunder, and otherwise in customary form and covering such financial and accounting matters as are customarily covered by letters of the independent certified public accountants delivered in connection with primary or secondary underwritten public offerings, as the case may be;

(x)  make generally available to its shareholders a consolidated earnings statement (which need not be audited) for the 12 months beginning after the effective date of a Registration Statement as soon as reasonably practicable after the end of such period, which earnings statement shall satisfy the requirements of an earning statement under Section 11(a) of the Securities Act; and

(1)  promptly notify each seller of Registrable Common Shares and the underwriter or underwriters, if any:

(2)  when the Registration Statement, any pre-effective amendment, the Prospectus or any Prospectus supplement or post-effective amendment to the Registration Statement has been filed and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective;

(3)  of any comments of the SEC or of any written request by the SEC for amendments or supplements to the Registration Statement or Prospectus;

(4)  of the notification to the Company by the SEC of its initiation of any proceeding with respect to the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement; and

(5)  of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Common Shares for sale under the applicable securities or blue sky laws of any jurisdiction.

(b)  The Company shall ensure that no Registration Statement (including any amendments or supplements thereto and Prospectuses contained therein) shall contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading (except, with respect to any Holder, for an untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made in reliance on and in conformity with written information furnished to the Company by or on behalf of such Holder specifically for use therein).

(c)  The Company shall make available to each Holder whose Registrable Common Shares are included in a Registration Statement (i) promptly after the same is

9

prepared and publicly distributed, filed with the SEC, or received by the Company, one copy of each Registration Statement and any amendment thereto, each preliminary Prospectus and Prospectus and each amendment or supplement thereto, each letter written by or on behalf of the Company to the SEC or the staff of the SEC (or other governmental agency or self-regulatory body or other body having jurisdiction, including any domestic or foreign securities exchange), and each item of correspondence from the SEC or the staff of the SEC (or other governmental agency or self-regulatory body or other body having jurisdiction, including any domestic or foreign securities exchange), in each case relating to such Registration Statement (other than any portion thereof which contains information for which the Company has sought confidential treatment), and (ii) such number of copies of a Prospectus, including a preliminary Prospectus, and all amendments and supplements thereto and such other documents as such Holder may reasonably request in order to facilitate the disposition of the Registrable Common Shares owned by such Holder.  The Company will promptly notify each Holder by facsimile of the effectiveness of each Registration Statement or any post-effective amendment.  The Company will promptly respond to any and all comments received from the SEC, with a view towards causing each Registration Statement or any amendment thereto to be declared effective by the SEC as soon as practicable and shall file an acceleration request as soon as practicable following the resolution or clearance of all SEC comments or, if applicable, following notification by the SEC that any such Registration Statement or any amendment thereto will not be subject to review.

(d)  At all times after the Company has filed a registration statement with the SEC pursuant to the requirements of either the Securities Act or the Exchange Act, the Company shall file all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, and take such further action as any Holders may reasonably request, all to the extent required to enable such Holders to be eligible to sell Registrable Common Shares pursuant to Rule 144 (or any similar rule then in effect).

(e)  The Company may require each seller of Registrable Common Shares as to which any registration is being effected to furnish to the Company any other information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request in writing.

(f)  Each seller of Registrable Common Shares agrees by having its shares treated as Registrable Common Shares hereunder that, upon notice of the happening of any event as a result of which the Prospectus included in such Registration Statement contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein not misleading (a “Suspension Notice”), such seller will forthwith discontinue disposition of Registrable Common Shares for a reasonable length of time not to exceed 60 days until such seller is advised in writing by the Company that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by Section 5(e) hereof, and, if so directed by the Company, such seller will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such seller’s possession, of the Prospectus covering such Registrable Common Shares current at the time of receipt of such notice;

10

provided, however, that such postponement of sales of Registrable Common Shares by the Holders shall not exceed ninety (90) days in the aggregate in any one year.  If the Company shall give any notice to suspend the disposition of Registrable Common Shares pursuant to a Prospectus, the Company shall extend the period of time during which the Company is required to maintain the Registration Statement effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date such seller either is advised by the Company that the use of the Prospectus may be resumed or receives the copies of the supplemented or amended Prospectus contemplated by Section 5(e).  In any event, the Company shall not be entitled to deliver more than three (3) Suspension Notices in any one year.

6.  REGISTRATION EXPENSES.

(a)  All expenses incident to the Company’s performance of or compliance with this Agreement, including, without limitation, all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, listing application fees, printing expenses, transfer agent’s and registrar’s fees, cost of distributing Prospectuses in preliminary and final form as well as any supplements thereto, and fees and disbursements of counsel for the Company and all independent certified public accountants and other Persons retained by the Company (but not including any underwriting discounts or commissions attributable to the sale of Registrable Common Shares or fees and expenses of counsel representing the Holders of Registrable Common Shares) (all such expenses being herein called “Registration Expenses”), relating to Demand Registrations shall be borne by the Holders participating in the Demand Registration in which such excess Registration Expenses are incurred with such Holders paying their portion of such excess Registration Expenses on a pro rata basis.  All Registration Expenses relating to Piggyback Registrations shall be borne on a pro rata basis between the Holders and the Company based on the number of shares being registered by each party in the offering.  In a Piggyback Registration, the Company shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which they are to be listed.

(b)  The obligation of the Company to bear the expenses described in Section 6(a) shall apply irrespective of whether a registration, once properly demanded, if applicable, becomes effective, is withdrawn or suspended, is converted to another form of registration and irrespective of when any of the foregoing shall occur; provided, however, that Registration Expenses for any Registration Statement withdrawn solely at the request of a Holder of Registrable Common Shares (unless withdrawn following postponement of filing by the Company in accordance with Section 2(d)(i) or (ii)) or any supplements or amendments to a Registration Statement or Prospectus resulting from a misstatement furnished to the Company by a Holder shall be borne by such Holder.

11

7.  INDEMNIFICATION.

(a)  The Company shall indemnify, to the fullest extent permitted by law, each Holder, its officers, directors and Affiliates and each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses arising out of or based upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or any violation or alleged violation by the Company of the Securities Act, the Exchange Act or applicable “blue sky” laws, except insofar as the same are made in reliance and in conformity with information relating to such Holder furnished in writing to the Company by such Holder expressly for use therein or caused by such Holder’s failure to deliver to such Holder’s immediate purchaser a copy of the Registration Statement or Prospectus or any amendments or supplements thereto (if the same was required by applicable law to be so delivered) after the Company has furnished such Holder with a sufficient number of copies of the same.  In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holders.

(b)  In connection with any Registration Statement in which a Holder of Registrable Common Shares is participating, each such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, shall indemnify, to the fullest extent permitted by law, the Company, its officers, directors Affiliates, and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to such Holder furnished in writing to the Company by such Holder expressly for use therein or caused by such Holder’s failure to deliver to such Holder’s immediate purchaser a copy of the Registration Statement or Prospectus or any amendments or supplements thereto (if the same was required by applicable law to be so delivered) after the Company has furnished such Holder with a sufficient number of copies of the same; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders and the liability of each such Holder shall be in proportion to and limited to the net amount received by such Holder from the sale of Registrable Common Shares pursuant to such Registration Statement.

(c)  Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification, provided that the failure to notify the indemnifying party shall not

12

relieve the indemnifying party from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to an indemnified party otherwise than under this Section 7 and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party.  If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld).  An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party which are in addition to or may conflict with those available to another indemnified party with respect to such claim.  Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

(d)  The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of securities.

(e)  If the indemnification provided for in or pursuant to this Section 7 is due in accordance with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses 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 result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations.  The relative fault of the indemnifying party on the one hand and of the indemnified Person on the other 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 by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  In no event shall the liability of any selling Holder be greater in amount than the amount of net proceeds received by such Holder upon such sale or the amount for which such indemnifying party would have been obligated to pay by way of indemnification if the indemnification provided for under Section 7(a) or 7(b) hereof had been available under the circumstances.

8.  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

9.  RULE 144.
