At any time and from time to time after 180 days following the commencement of the Initial Offering, upon written request by the Requisite Holders that the Company effect the registration under the Securities Act of all or part of the Registrable Securities (a "Demand Request"), the Company will use reasonable best efforts to register the Registrable Securities which the Company has been so requested to register by the Holders under the Securities Act for resale by the Holders in an underwritten offering (a "Subsequent Offering") pursuant to a registration statement (the "Subsequent Registration Statement") that has been declared effective by the Commission, which registration statement shall be kept effective by the Company until the earlier of such time as the Subsequent Offering is completed or the expiration of 60 days following the effectiveness of the Subsequent Registration Statement. The Company will use reasonable best efforts to have each Subsequent Registration Statement declared effective by the Commission within ninety (90) days after receipt of such request or within sixty (60) days after receipt of such request if the Company is qualified to file a registration statement on Commission Form S-3, S-2 or any successor or similar short-form registration statement (collectively, "Commission Form S-3"). Subject to subdivision (g), the Company may include in such Subsequent Registration Statement and Subsequent Offering other securities of the Company for sale, for the Company's account or for the account of any other person. Upon receipt of a Demand Request, the Company shall promptly give written notice of such request to all Holders, and all Holders shall be afforded the opportunity to participate in such request as follows: subject to subdivision (g), the Company will include in each Subsequent Registration Statement and Subsequent Offering such number of Registrable Securities of any Holder joining in such request as are specified in a written request by the Holder received by the Company within 20 days after receipt of such written notice from the Company. (c) INCIDENTAL REGISTRATION. For so long as Registrable Securities are outstanding, if the Company for itself or any of its security holders shall at any time or times after the date hereof determine to register under the Securities Act any shares of its capital stock or - 3 - other securities (other than: (i) the registration of an offer, sale or other disposition of securities solely to employees of, or other persons providing services to, the Company, or any subsidiary pursuant to an employee or similar benefit plan; or (ii) the issuance of securities in a merger, acquisition or other transaction of the type described in Rule 145 under the Securities Act or a comparable or successor rule, registered on Form S-4 or similar or successor forms), on each such occasion the Company will notify each Holder of Registrable Securities of such determination at least thirty (30) days prior to the filing of such registration statement, and upon the request of any Holder given in writing within twenty (20) days after the receipt of such notice, the Company will cause any of the Registrable Securities specified by any such Holder to be included in such registration statement to the extent such registration is permissible under the Securities Act and subject to the conditions of the Securities Act and subdivision (g) (an "Incidental Registration"). (d) REGISTRATION STATEMENT FORM. The Company shall, if permitted by law, effect any registration requested under Section 2 by the filing of a registration statement on Commission Form S-3. (e) EXPENSES. The Company shall pay all Registration Expenses incurred in connection with the Initial Registration Statement, any Subsequent Registration Statement and any Incidental Registration Statement. Those Holders of Registrable Securities participating in the Initial Offering, any Subsequent Offering and any Incidental Registration shall bear their respective PRO RATA share of any applicable underwriting discounts and commissions; such participating Holders agree that the proceeds received by them upon consummation of any such offering shall be net of any and all such discounts and commissions. (f) EFFECTIVE REGISTRATION STATEMENT. Neither the Initial Registration Statement, a Subsequent Registration Statement, nor an Incidental Registration requested pursuant to this Section 2 shall be deemed to have been effected until it has become effective with the Commission. Notwithstanding the foregoing, a registration statement will not be deemed to have been effected if: (i) after it has become effective with the Commission, such registration is interfered with by any stop order, injunction, or other order or requirement of the Commission or other governmental agency or any court proceeding for any reason other than a misrepresentation or omission by any Holder; or (ii) the conditions to consummation of the Initial Offering or any Subsequent Offering contained in the underwriting agreement entered into in connection with such registration are not satisfied, other than solely by reason of some act or omission by any Holder. (G) PRIORITY IN UNDERWRITTEN REGISTRATIONS. If a registration is an underwritten registration and the managing underwriters shall give written advice to the Company and the Persons requesting such registration that, in their opinion, market conditions dictate that no more than a specified maximum number of securities could successfully be included in such registration, then the maximum number of securities included in such registration statement shall be limited to such specified number, and the rights of the - 4 - Holders to participate in such registration shall be subject to the following cutback provisions: (i) In the case of the Initial Offering, the securities sought to be included in such offering by the Holders shall be excluded on a PRO RATA basis with the securities sought to be included in the Initial Offering by the Company and all other Persons seeking inclusion of securities in such offering (including pursuant to so-called piggyback registration rights), based upon the Holder's, the Company's and the other Persons' relative number of securities sought to be so included until the aggregate market value of the securities sought to be included in such offering by the Holders has been reduced to approximately $125 million, after which any additional securities required to be excluded from such offering in order to comply with the advice of the managing underwriter shall be securities that were to have been offered for the Company's account until the offering includes no such securities, after which the securities sought to be included in such offering by the Holders shall be excluded on a PRO rata basis with the securities sought to be included in the Initial Offering by all other Persons seeking inclusion of securities in such offering (including pursuant to so-called piggyback registration rights), based upon the Holder's and the other Persons' relative number of securities sought to be so included; (ii) In the case of any Subsequent Offering, (a) the securities sought to be included in such offering by the Company for its own account shall have priority for inclusion over any Registrable Securities held by the Holders and (b) Registrable Securities held by the Holders may be excluded on a PRO RATA basis with all other Persons seeking inclusion of securities in such offering pursuant to the exercise of so-called piggyback registration rights, based upon such Holder's and other Persons' relative number of securities sought to be so included; and (iii) If the registration is an Incidental Registration, (a) the securities sought to be registered by the Company for its own account shall have priority for inclusion, (b) the securities sought to be registered for the account of other Persons exercising demand registration rights shall have priority for inclusion to the extent such rights require such priority and (c) Registrable Securities held by the Holders may be excluded on a PRO RATA basis with all other Persons seeking inclusion of securities in such registration pursuant to the exercise of so-called piggyback registration rights, based upon such Holder's and other Persons' relative number of securities sought to be so included. (h) BLACKOUT AND POSTPONEMENT. Notwithstanding anything in paragraphs (a), (b), and (c) of this Section 2, the Company shall have the right (i) to delay any registration of Registrable Securities requested pursuant to paragraph (a), (b) or (c) of this Section 2 or (ii) upon written notice to the Holders, to prohibit the Holders from selling Registrable Securities under the Initial Registration Statement, any Subsequent Registration Statement, or any Incidental Registration, in any case for up to 120 days if such - 5 - registration or sale, as applicable, would, in the judgment of the Company as reflected in an officer's certificate delivered to the Holders, require disclosures that would not be in the Company's best interest to make at such time, as applicable; PROVIDED, HOWEVER, that (i) the Initial Registration Statement and the Initial Offering shall not be delayed or blacked-out for more than 120 days in the aggregate and (ii) registrations other than the Initial Registration Statement shall not be delayed and/or sale prohibitions relating to offerings other than the Initial Offering shall not be in effect pursuant to the provisions of this paragraph (h) for more than 270 days during any period of 365 days. The time period during which any sale prohibition relating to the Initial Registration Statement or a Subsequent Registration Statement is in effect under this Section 2(h) shall be added to the time period for which the Initial Registration Statement or a Subsequent Registration Statement, as the case may be, is otherwise required to remain effective under this Agreement. 3. REGISTRATION PROCEDURES. (a) If and whenever the Company is required to effect the registration of any Registrable Securities under the Securities Act as provided in Section 2, the Company, as expeditiously as possible and subject to the terms and conditions of Section 2, will: (i) prepare and file with the Commission the requisite registration statement to effect such registration and use its best efforts to cause such registration to become and remain effective; (ii) permit any Holder which, in the reasonable judgment of the Holder, might be deemed to be an underwriter or a controlling person of the Company, to participate in the preparation of such registration 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 and which is not reasonably objected to by the Company and its counsel; (iii) 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 and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement until the earlier of such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement or the expiration of 60 days after such registration statement becomes effective (in the case of the Initial Registration Statement or a Subsequent Registration Statement); (iv) furnish to the Holders such number of conformed copies of such registration statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus - 6 - and any summary prospectus) and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such other documents, as the purchaser or any Holder of Registrable Securities to be sold under such registration statement may reasonably request in order to facilitate the distribution of such Registrable Securities; (v) use its best efforts to register or qualify all Registrable Securities covered by such registration statement under such other United States state securities or blue sky laws of such jurisdictions as any Holder of Registrable Securities to be sold under registration statement shall reasonably request, to keep such registration or qualification in effect for so long as such registration remains in effect, and take any other action which may be customary in similar offerings to enable the Holder of Registrable Securities to be sold under such registration statement to consummate the disposition in such jurisdictions of the securities owned by such Holder, except that the Company shall not for any such purpose be required to (a) qualify generally to do business as a foreign corporation in any jurisdiction wherein it would not but for the requirements of this subdivision (v) be obligated to be so qualified, or (b) subject itself to taxation in any such jurisdiction. (vi) use its best efforts to cause all Registrable Securities covered by such registration statement to be registered with or approved by such other United States state governmental agencies or authorities as may be necessary to enable the Holder of Registrable Securities to be sold under such registration statement to consummate the intended disposition of such Registrable Securities; (vii) in the event of the issuance of any stop order suspending the effectiveness of the registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Registrable Securities included in such registration statement for sale in any jurisdiction, the Company shall use its best efforts promptly to obtain the withdrawal of such order; (viii) furnish to the Holders of Registrable Securities to be sold under such registration statement an opinion, dated the effective date of the registration statement, of the independent counsel representing the Company for the purposes of such registration, addressed to the underwriters, if any, and to the Holders making such request, stating that such registration statement has become effective under the Securities Act and that (i) 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; (ii) the registration statement, the related prospectus, and each amendment or supplement thereto, comply as to form in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder (except that such counsel need express - 7 - no opinion as to financial statements and related schedules and other projected financial or statistical data contained therein); (iii) the descriptions in the registration statement or the prospectus, or any amendment or supplement thereto, of all legal and governmental matters and contracts and other legal documents or instruments are accurate and fairly present the information required to be shown; and (v) such counsel does not know of any legal or governmental proceedings, pending or contemplated, required to be described in the registration statement or prospectus, or any amendment or supplement thereto, which are not described as required nor of any contracts or documents or instruments of a character required to be described in the registration statement or prospectus, or any amendment or supplement thereto or to be filed as exhibits to the registration statement which are not described and filed as required. Such counsel shall also opine that, in the course of assisting the Company in preparing the Registration Statement, nothing has come to their attention that would cause them to believe that the Registration Statement (excluding the financial and statistical information contained therein) contains any untrue statement of a material fact or omits a material fact necessary to make the statements therein, in light of the circumstances under which they were made not misleading. (ix) furnish to the Holders of Registrable Securities to be sold under the Registration Statement a letter, dated the effective date of the registration statement, from the independent certified public accountants of the Company, addressed to the underwriters, if any, and to the Holders making such request, stating that they are independent certified public accountants within the meaning of the Securities Act and that in the opinion of such accountants, the financial statements and other financial data of the Company included in the registration statement or the prospectus, or any amendment or supplement thereto, comply as to form in all material respects with the applicable accounting requirements of the Securities Act. Such letter from the independent certified public accountants shall additionally cover such other financial matters (including information as to the period ending not more than five business days prior to the date of such letter) with respect to the registration in respect of which such letter is being given as the Holders may reasonably request. (x) immediately notify the Holders of Registrable Securities included in 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 as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and at the request of the Holders promptly prepare and furnish to the Holders a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include an untrue statement of a material - 8 - fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; (xi) otherwise use all reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months, but not more than eighteen months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder, and not file any amendment or supplement to such registration statement or prospectus to which any Holder shall have reasonably objected in writing on the grounds that such amendment or supplement does not comply in all material respects with the requirements of the Securities Act or of the rules or regulations thereunder, having been furnished with a copy thereof at least two business days prior to the filing thereof to the extent reasonably possible; (xii) provide a transfer agent for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement; (xiii) use all reasonable best efforts to cause to be quoted or listed all Registrable Securities covered by such registration statement on NASDAQ and any securities exchange on which any of the Registrable Securities are then quoted or listed; (xiv) confer with the Stockholders' Representative as to mutually beneficial and appropriate time to schedule the Initial Offering and the first Subsequent Offering and make available the Company's management to participate in roadshow presentations and conference calls with respect to such offerings; and (xv) confer with the Stockholders' Representative as to mutually beneficial and appropriate time to schedule any other underwritten offerings of Company Common Stock that will include Registrable Securities and use all reasonable best efforts to work with the Stockholders' Representative to schedule such offerings so that the Company's management will be able to participate in roadshow presentations and conference calls with respect to any additional Subsequent Offerings in excess of $100 million, the availability of its senior management, however, being subject to conflicting business necessities. (b) As a condition to the Company's obligation under this Section with respect to any Holder, the Company may require such Holder of Registrable Securities to be sold under such registration statement, at the Company's expense, to furnish the Company with such information and undertakings as it may reasonably request regarding such Holder and the - 9 - distribution of such securities as the Company may from time to time reasonably request in writing. (c) Each Holder, by execution of this Agreement, agrees (A) that upon receipt of any notice of the Company of the happening of any event of the kind described in subdivision (a)(x) of this Section 3, such Holder will forthwith discontinue its disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until the receipt by such Holder of the copies of the supplemented or amended prospectus contemplated by subdivision (a)(x) of this Section 3 and, if so directed by the Company, will deliver to the Company all copies (other than permanent file copies), then in possession of the Holders of the prospectus relating to such Registrable Securities current at the time of receipt of such notice and (B) that it will immediately notify the Company, at any time when a prospectus relating to the registration of such Registrable Securities is required to be delivered under the Securities Act, of the happening of any event as a result of which information previously furnished in writing by such Holder to the Company for inclusion in such prospectus contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made. In the event the Company or any such Holder shall give any such notice, the period referred to in subdivision (a)(iii) of this Section 3 shall be extended by a number of days equal to the number of days during the period from and including the giving of notice pursuant to subdivision (a)(x) of this Section 3 to and including the date when such Holder shall have received the copies of the supplemented or amended prospectus contemplated by subdivision (a)(x) of this Section 3. 4. UNDERWRITTEN OFFERINGS. (a) UNDERWRITTEN OFFERING. In connection with any underwritten offering pursuant to a registration under Section 2, the Company will enter into an underwriting agreement with the underwriters for such offering, such agreement to be in form and substance reasonably satisfactory to all Holders requesting such registration and such underwriters in their reasonable judgment and to contain such representations and warranties by the Company and such other terms as are customarily contained in agreements of that type, including, without limitation, indemnities to the effect and to the extent provided in Section 6. Each such Holder shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of each such Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of each such Holder. No Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder and its intended method of distribution and any other representation required by law. - 10 - (b) SELECTION OF UNDERWRITERS. The Company shall select its customary underwriter or, alternatively, an underwriting firm of national reputation, with expertise in comparable offerings by companies engaged in businesses similar to that of the Company that is reasonably satisfactory to the Stockholders' Representative, for the Initial Offering, any Subsequent Offering and any underwritten offering pursuant to an Incidental Registration. (c) HOLDBACK AGREEMENTS. Each Holder agrees, if required by the managing underwriter in any offering, not to effect any public sale or distribution of Registrable Securities (other than sales pursuant to the Initial Registration Statement), any sale or distribution thereof pursuant to Rule 144 or 145 under the Securities Act, or any short sale thereof or any transaction or series of transactions having a substantially similar economic effect during the period beginning, in the case of the Initial Registration Statement, on the date hereof and ,in the case of each Subsequent and Incidental Registration, beginning seven days prior to the effective date of such registration statement, and ending on the date 180 days after the Initial Registration Statement, any Subsequent Registration Statement or any Incidental Registration Statement shall have been declared effective, PROVIDED that in the event the Initial Registration Statement shall not have been declared effective within 30 days following the Closing Date and a majority-in-interest of the Holders participating in the Initial Offering shall have voted to be released, in whole or in part, from such restrictions, all of the Holders shall be released, in whole or in part, as so determined, from such restrictions with respect to the Initial Offering. In addition, if (i) the gross proceeds to the Holders in the Initial Offering are less than $150 million and a majority-in-interest of the Holders participating in such offering vote to be released, in whole or in part, from the restrictions contained in the preceding sentence or (ii) the gross proceeds to the Holders in any Subsequent Offering are less than $30 million and a majority-in-interest of all Holders of Registrable Securities vote to be released, in whole or in part, from the restrictions contained in the preceding sentence then all Holders shall be released from the restrictions contained in the preceding sentence with respect to such offering, in whole or in part, as so determined. 5. PREPARATION, REASONABLE INVESTIGATION. In connection with the preparation and filing of each registration statement under the Securities Act, the Company will give the Stockholders' Representative, the underwriters, if any, and their respective counsel and accountants, drafts and final copies of such registration statement, each prospectus included therein or filed with the Commission and each amendment thereof or supplement thereto, at least 5 business days prior to the filing thereof with the Commission, and will give each of them such access to its books and records and such opportunities to discuss the business of the Company with its officers and the independent public accountants who have certified its financial statements as shall be necessary, in the opinion of such Holders' and such underwriters' respective counsel, to conduct a reasonable investigation within the meaning of the - 11 - Securities Act. 6. INDEMNIFICATION AND CONTRIBUTION. (a) INDEMNIFICATION BY THE COMPANY. In the event of any registration under the Securities Act pursuant to Section 2 of any Registrable Securities covered by such registration, the Company will, and hereby does, indemnify and hold harmless each Holder of Registrable Securities to be sold under such registration statement, each such Holder's legal counsel, each other person who participates as an underwriter in the offering or sale of such securities (if so required by such underwriter as a condition to including the Registrable Securities of the Holders in such registration) and each other person, if any, who controls any such Holder or any such underwriter within the meaning of the Securities Act (collectively, the "Indemnified Parties"), against any losses, claims, damages or liabilities, joint or several, to which the Holders or underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, 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 securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein or any document incorporated therein by reference, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or arise out of any violation by the Company of any rule or regulation promulgated under the Securities Act or state securities law applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, and the Company will reimburse the Indemnified Parties for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; PROVIDED, HOWEVER, that the Company shall not be liable to any Indemnified Party in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Indemnified Party specifically for use therein. (b) INDEMNIFICATION BY THE HOLDERS. The Company may require, as a condition to including any Registrable Securities of any Holder in any registration statement filed pursuant to Section 2, that the Company shall have received an undertaking reasonably satisfactory to it from such Holder to indemnify and hold harmless (in the same manner and to the same extent as set forth in subdivision (a) of this Section 6) the Company, each director of the Company, each officer of the Company and each other person, if any, who controls the Company within the meaning of the Securities Act, with respect to any - 12 - statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if, and only if, and only to the extent that, such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with information furnished in writing to the Company directly by such Holder specifically for use therein; provided, however, that the obligation of any Holder hereunder shall be limited to an amount equal to the net proceeds received by such Holder upon the sale of Registrable Securities sold in the offering covered by such registration. (c) NOTICES OF CLAIMS, ETC. Promptly after receipt by an Indemnified Party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding subdivisions of this Section 6, such Indemnified Party will, if a claim in respect thereof is to be made against a party required to provide indemnification (an "Indemnifying Party"), give written notice to the latter of the commencement of such action, PROVIDED, HOWEVER, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligation under the preceding subdivisions of this Section 6, except to the extent that the Indemnifying Party is actually prejudiced by such failure to give notice. In case any such action is brought against an Indemnified Party, unless in such Indemnified Party's reasonable judgment a conflict of interest between such Indemnified and indemnifying parties may exist in respect of such claim, the Indemnifying Party shall be entitled to participate in and to assume the defense thereof, jointly with any other Indemnifying Party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense thereof, the Indemnifying Party shall not be liable to such Indemnified Party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. No Indemnifying Party shall consent to entry of any judgment or enter into any settlement without the consent of the Indemnified Party which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (d) OTHER INDEMNIFICATION. Indemnification substantially equivalent to that specified in the preceding subdivisions of this Section 6 (with appropriate modifications) shall be given by the Company and each Holder of Registrable Securities included in any registration statement with respect to any required registration or other qualification of securities under any Federal or state law or regulation of any governmental authority, other than the Securities Act. (e) INDEMNIFICATION PAYMENT. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred. - 13 - (f) SURVIVAL OF OBLIGATIONS. The obligations of the Company and of the Holders under this Section 6 shall survive the completion of any offering of Registrable Securities under this Agreement. (g) CONTRIBUTION. If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an Indemnified Party, then each Indemnifying Party shall contribute to the amount paid or payable to such Indemnified Party as a result of the losses, claims, damages or liabilities referred to in this Section 6 an amount or additional amount, as the case may be, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party or parties on the one hand and the Indemnified Party on the other in connection with the statements or omissions which resulted in such losses, claims, demands or liabilities as well as any other relevant equitable considerations. The relative fault 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 parties on the one hand or the Indemnified Party on the other and the parties' relative, intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid to an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 6(g) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim which is the subject of this Section 6. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 7.
