The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).

The purchase by such Purchaser of the Shares, the Additional Investment Rights and the Warrants hereunder has been duly authorized by all necessary action on the part of such Purchaser. This Agreement has been duly executed and delivered by such Purchaser and constitutes the valid and binding obligation of such Purchaser, enforceable against it in accordance with its terms.

(b) Investment Intent. Such Purchaser is acquiring the Securities as principal for its own account for investment purposes only and not with a view to or for distributing or reselling such Securities or any part thereof, without prejudice, however, to such Purchaser's right, subject to the provisions of this Agreement, at all times to sell or otherwise dispose of all or any part of such Securities pursuant to an effective registration statement under the Securities Act or under an exemption from such registration and in compliance with applicable federal and state securities laws.

Such Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

(a) Securities may only be disposed of pursuant to an effective registration statement under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with any applicable state securities laws.

Notwithstanding the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its transfer agent, without any such legal opinion, any transfer of Securities by a Purchaser to an Affiliate of such Purchaser, provided that the transferee certifies to the Company that it is an "accredited investor" as defined in Rule 501(a) under the Securities Act and such transferee executes a joinder to this Agreement.

(b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1(b), of the following legend on any certificate evidencing Securities:

Certificates evidencing Securities shall not be required to contain such legend or any other legend (i) while a Registration Statement covering the resale of such Securities is effective under the Securities Act, or (ii) following any sale of such Securities pursuant to Rule 144, or (iii) if such Securities are eligible for sale under Rule 144(k). The Company shall cause its counsel to issue the legal opinion included in the Transfer Agent Instructions to the Company's transfer agent on the Effective Date. Following the Effective Date or at such earlier time as a legend is no longer required for certain Securities, the Company will no later than three Trading Days following the delivery by a Purchaser to the Company or the Company's transfer agent of a legended certificate representing such Securities, deliver or cause to be delivered to such Purchaser a certificate representing such Securities that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section, except as required by law, regulation or the requirements of the applicable Trading Market. Each Purchaser, individually as to itself only, agrees to indemnify the Company or any of its officers or directors from any Losses and any reasonable legal and other expenses (including the costs of any investigation, preparation and travel) arising solely out of such Purchaser's failure to (i) comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of the Registrable Securities pursuant to the Registration Statement, or (ii) sell such Registrable Securities in a manner described in the Registration Statement. The indemnification obligations under this paragraph shall be in addition to any liability that the Purchaser may otherwise have and shall be binding upon and inure to the benefit of any successors or assigns of the Company.

(c) The Company acknowledges and agrees that a Purchaser may from time to time pledge or grant a security interest in some or all of the Securities in connection with a bona fide margin agreement or other loan or financing arrangement secured by the Securities and, if required under the terms of such agreement, loan or arrangement, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser's expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder.

(d) Certain Trading Limitations. Each Purchaser agrees that beginning on the date hereof until the earlier to occur of (a) 120 days from the Closing Date and (b) the Effective Date of the Registration Statement, it will not enter into any Short Sales. For purposes of this Section 4.1(d), a "Short Sale" by a Purchaser means a sale of Common Stock that is marked as a short sale and that is executed at a time when such Purchaser has no equivalent offsetting long position in the Common Stock. For purposes of determining whether a Purchaser has an equivalent offsetting long position in the Common Stock, all Common Stock and all Common Stock that would be issuable upon conversion or exercise in full of all Options then held by such Purchaser (assuming that such Options were then fully convertible or exercisable, notwithstanding any provisions to the contrary, and giving effect to any conversion or exercise price adjustments scheduled to take effect in the future) shall be deemed to be held long by such Purchaser.

(a) From the date hereof until the Effective Date, the Company will not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of) any of its or the Subsidiaries' equity or equity equivalent securities, including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for Common Stock or Common Stock Equivalents (any such offer, sale, grant, disposition or announcement being referred to as a "Subsequent Placement").

(b) From the Effective Date until 30 Trading Days after the Effective Date (the "Blockout Period"), the Company will not, directly or indirectly, effect any Subsequent Placement except as set forth in Section 4.5(e).

(c) The Blockout Period set forth in Section 4.5(b) above shall be extended for the number of Trading Days during such period in which (i) trading in the Common Stock is suspended by any Trading Market, (excluding general suspensions of trading in such Trading Market), (ii) the Registration Statement is not effective after the Required Effectiveness Date, or (iii) the prospectus included in the Registration Statement may not be used by the Purchasers for the resale of Registrable Securities thereunder.

(d) From the end of the Blockout Period until the one year anniversary thereof, the Company will not, directly or indirectly, effect any Subsequent Placement unless the Company shall have first complied with this Section 4.5(d).

(e) The restrictions contained in paragraphs (a), (b) and (d) of this Section 4.5 shall not apply to Excluded Stock.

(a) Representations and Warranties. The representations and warranties of the Company contained herein shall be true and correct in all material respects as of the date when made and as of the Closing as though made on and as of such date; and

(b) Performance. The Company and each other Purchaser shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by the Transaction Documents to be performed, satisfied or complied with by it at or prior to the Closing.

(a) Representations and Warranties. The representations and warranties of the Purchasers contained herein shall be true and correct in all material respects as of the date when made and as of the Closing Date as though made on and as of such date; and

(b) Performance. The Purchasers shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by the Transaction Documents to be performed, satisfied or complied with by the Purchasers at or prior to the Closing.

(a) As promptly as possible, and in any event on or prior to the Filing Date, the Company shall prepare and file with the Commission a "Shelf" Registration Statement covering the resale of all Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith as the Purchasers may consent) and shall contain (except if otherwise directed by the Purchasers) the "Plan of Distribution" attached hereto as Exhibit D.

(b) The Company shall use its best efforts to cause the Registration Statement to be declared effective by the Commission as promptly as possible after the filing thereof, but in any event prior to the Required Effectiveness Date, and shall use its best efforts to keep the Registration Statement continuously effective under the Securities Act until the fifth anniversary of the Effective Date or such earlier date when all Registrable Securities covered by such Registration Statement have been sold publicly or may be sold pursuant to paragraph (k) of Rule 144 (the "Effectiveness Period").

(c) The Company shall notify each Purchaser in writing promptly (and in any event within one business day) after receiving notification from the Commission that the Registration Statement has been declared effective.

(d) (d) Subject to Section 6.1(e) below, upon the occurrence of any Event (as defined below) and on every monthly anniversary thereof until the applicable Event is cured, as partial relief for the damages suffered therefrom by the Purchasers (which remedy shall not be exclusive of any other remedies available under this Agreement, at law or in equity), the Company shall pay to each Purchaser an amount in cash, as liquidated damages and not as a penalty, equal to 1.0% of the aggregate purchase price paid by such Purchaser hereunder for the first month and 1.5% for each month thereafter, prorated for any partial month. The payments to which a Purchaser shall be entitled pursuant to this Section 6.1(d) are referred to herein as "Event Payments". Any Event Payments payable pursuant to the terms hereof shall apply on a pro-rata basis for any portion of a month prior to the cure of an Event. In the event the Company fails to make Event Payments in a timely manner, such Event Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full.

For such purposes, each of the following shall constitute an "Event":

(e) Notwithstanding anything in this Agreement to the contrary, the Company may, by written notice to the Purchasers, suspend sales under a Registration Statement after the Effective Date thereof and/or require that the Purchasers immediately cease the sale of shares of Common Stock pursuant thereto and/or defer the filing of any subsequent Registration Statement if at any time the Company determines in good faith that such Registration Statement contains 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, in the light of the circumstances under which they were made, not misleading and cannot be utilized in connection with the sale of shares of Common Stock until it has been appropriately amended. Upon receipt of such notice, each Purchaser shall immediately discontinue any sales of Registrable Securities pursuant to such registration until such Purchaser has received copies of a supplemented or amended Prospectus or until such Purchaser is advised in writing by the Company that the then-current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. In no event, however, shall this right be exercised to suspend sales beyond the period during which (in the good faith determination of the Company) the failure to require such suspension would be materially detrimental to the Company. Furthermore, in no event may the Company exercise its rights hereunder more than two times or for a period of more than 30 days in any twelve month period. Immediately after the end of any suspension period under this Section 6.1(e), the Company shall take all necessary actions (including filing any required supplemental prospectus) to restore the effectiveness of the applicable Registration Statement and the ability of the Purchasers to publicly resell their Registrable Securities pursuant to such effective Registration Statement.

(f) The Company shall not, prior to the Effective Date of the Registration Statement, prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities. 

(a) (a) Not less than three Trading Days prior to the filing of a Registration Statement or any related Prospectus or any amendment, or not less than one Trading Day for any supplement thereto (including any document that would be incorporated or deemed to be incorporated therein by reference), the Company shall (i) furnish to each Purchaser and any counsel designated by any Purchaser (each, a "Purchaser Counsel", and Vertical Ventures, LLC, a Purchaser, has initially designated Proskauer Rose LLP as its Purchaser Counsel) copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of each Purchaser and Purchaser Counsel, and (ii) cause its officers and directors, counsel and independent certified public accountants to respond to such reasonable inquiries as shall be necessary, in the reasonable opinion of respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file a Registration Statement or any such Prospectus or any amendments or supplements thereto to which Purchasers holding a majority of the Registrable Securities shall reasonably object in writing within three Trading Days of receiving (or one Trading Day in the case of supplements).

(b) (i) Prepare and file with the Commission such amendments, including post-effective amendments, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible, and in any event within ten days, to any comments received from the Commission with respect to the Registration Statement or any amendment thereto and promptly provide the Purchasers true and complete copies of all correspondence from and to the Commission relating to the Registration Statement; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by the Registration Statement during the applicable period in accordance with the intended methods of disposition by the Purchasers thereof set forth in the Registration Statement as so amended or in such Prospectus as so supplemented

(c) Notify the Purchasers of Registrable Securities to be sold and each Purchaser Counsel as promptly as reasonably possible, and (if requested by any such Person) confirm such notice in writing no later than one Trading Day thereafter, of any of the following events: (i) the Commission notifies the Company whether there will be a "review" of any Registration Statement; (ii) the Commission comments in writing on any Registration Statement (in which case the Company shall deliver to each Purchaser a copy of such comments and of all written responses thereto); (iii) any Registration Statement or any post-effective amendment is declared effective; (iv) the Commission or any other Federal or state governmental authority requests any amendment or supplement to any Registration Statement or Prospectus or requests additional information related thereto; (v) the Commission issues any stop order suspending the effectiveness of any Registration Statement or initiates any Proceedings for that purpose; (vi) the Company receives notice of any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, or the initiation or threat of any Proceeding for such purpose; or (vii) the financial statements included in any Registration Statement become ineligible for inclusion therein or any statement made in any Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference is untrue in any material respect or any revision to a Registration Statement, Prospectus or other document is required so that it will not contain any untrue statement of a material fact or omit to state any 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.

(d) Use its best efforts to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of any Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as possible.

(e) Furnish to each Purchaser and Purchaser Counsel, without charge, at least one conformed copy of each Registration Statement and each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission.

(f) Promptly deliver to each Purchaser and Purchaser Counsel, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Purchasers in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(g) (i) In the time and manner required by each Trading Market, prepare and file with such Trading Market an additional shares listing application covering all of the Registrable Securities; (ii) take all steps necessary to cause such Registrable Securities to be approved for listing on each Trading Market as soon as possible thereafter; (iii) provide to the Purchasers evidence of such listing (if applicable); and (iv) maintain the listing of such Registrable Securities on each such Trading Market or another Eligible Market.

(h) Prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate with the selling Purchasers and respective Purchaser Counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Purchaser requests in writing, to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement.

(i) Cooperate with the Purchasers to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by this Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Purchasers may request.

(j) Upon the occurrence of any event described in Section 6.2(c)(vii), as promptly as reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither the Registration Statement nor such Prospectus will 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.

(k) Cooperate with any due diligence investigation undertaken by the Purchasers in connection with the sale of Registrable Securities, including, without limitation, by making available any documents and information; provided that the Company will not deliver or make available to any Purchaser material, nonpublic information unless such Purchaser specifically requests in advance to receive material, nonpublic information in writing.

(l) Comply with all applicable rules and regulations of the Commission. 

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Purchaser, the officers, directors, partners, members, agents, brokers, investment advisors and employees of each of them, each Person who controls any such Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all Losses, as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (i) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding such Purchaser furnished in writing to the Company by such Purchaser expressly for use therein, or to the extent that such information relates to such Purchaser or such Purchaser's proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (ii) in the case of an occurrence of an event of the type specified in Section 6.2(c)(v)-(vii), the use by such Purchaser of an outdated or defective Prospectus after the Company has notified such Purchaser in writing that the Prospectus is outdated or defective and prior to the receipt by such Purchaser of the Advice contemplated in Section 6.5. The Company shall notify the Purchasers promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.

(b) Indemnification by Purchasers. Each Purchaser shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising solely out of any untrue statement of a material fact contained in the Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising solely out of any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Purchaser to the Company specifically for inclusion in such Registration Statement or such Prospectus or to the extent that (i) such untrue statements or omissions are based solely upon information regarding such Purchaser furnished in writing to the Company by such Purchaser expressly for use therein, or to the extent that such information relates to such Purchaser or such Purchaser's proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (ii) in the case of an occurrence of an event of the type specified in Section 6.2(c)(v)-(vii), the use by such Purchaser of an outdated or defective Prospectus after the Company has notified such Purchaser in writing that the Prospectus is outdated or defective and prior to the receipt by such Purchaser of the Advice contemplated in Section 6.5. In no event shall the liability of any selling Purchaser hereunder be greater in amount than the dollar amount of the net proceeds received by such Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an "Indemnified Party"), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the "Indemnifying Party") in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised in writing by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party provided that such separate counsel shall be reasonably satisfactory to the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying Party, together with reasonable documentation of such expenses, (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

(d) Contribution. If a claim for indemnification under Section 6.4(a) or (b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 6.4(c), any reasonable attorneys' or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6.4(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 6.4(d), no Purchaser shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Purchaser from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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.

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.
