In addition, the Purchaser is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interest. 2.3 RELIANCE ON EXEMPTIONS.

(b) advise the Holders within five Business Days: (i) when the Registration Statement or any amendment thereto has been filed with the SEC and when the Registration Statement or any post-effective amendment thereto has become effective; (ii) of any request by the SEC for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for such purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (v) of the occurrence of any event that requires the making of any changes in the Registration Statement or the prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading; (c) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time; (d) promptly furnish to each Holder, without charge, at least one copy of such Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits in the form filed with the SEC; (e) during the Registration Period, promptly deliver to each Holder, without charge, as many copies of the prospectus included in such Registration Statement and any amendment or supplement thereto as such Holder may reasonably request; and the Company consents to the use, consistent with the provisions hereof, of the prospectus or any amendment or supplement thereto by each of the selling Holders of Registrable Securities in connection with the offering and sale of the Registrable Securities covered by the prospectus or any amendment or supplement thereto. In addition, upon the reasonable request of the Holder and subject in all cases to confidentiality protections reasonably acceptable to the Company, the Company will meet with a Holder or a representative thereof at the Company's headquarters to discuss all information relevant for disclosure in the Registration Statement covering the Registrable Securities, and will otherwise cooperate with any Holder conducting an investigation for the purpose of reducing or eliminating such Holder's exposure to liability under the Securities Act, including the reasonable production of information at the Company's headquarters; (f) during the Registration Period, promptly deliver to each Holder, without charge, (i) as soon as practicable (but in the case of the annual report of the Company to its stockholders, within 120 days after the end of each fiscal year of the Company) one copy of the following documents, other than those documents available via EDGAR: (A) its annual report to 13. its stockholders, if any (which annual report shall contain financial statements audited in accordance with generally accepted accounting principles in the United States of America by a firm of certified public accountants of recognized standing); (B) if not included in substance in its annual report to stockholders, its annual report on Form 10-K (or similar form); (C) each of its quarterly reports to its stockholders, and, if not included in substance in its quarterly reports to stockholders, its quarterly report on Form 10-Q (or similar form), and (D) a copy of the full Registration Statement (the foregoing, in each case, excluding exhibits); and (ii) upon reasonable request, all exhibits excluded by the parenthetical to the immediately preceding clause (D), and all other information that is generally available to the public; (g) prior to any public offering of Registrable Securities pursuant to any Registration Statement, promptly take such actions as may be necessary to register or qualify or obtain an exemption for offer and sale under the securities or blue sky laws of such jurisdictions as any such Holders reasonably request in writing, provided that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Securities covered by such Registration Statement; (h) upon the occurrence of any event contemplated by Section 6.4(b)(v) above, the Company shall use its commercially reasonable efforts to promptly prepare a post?effective amendment to the Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; (i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC which could affect the sale of the Registrable Securities; (j) use its commercially reasonable efforts to cause all Registrable Securities to be listed on each securities exchange or market, if any, on which equity securities issued by the Company have been listed; and (k) use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated hereby and to enable the Holders to sell Registrable Securities under Rule 144. 6.6 The Holders shall have no right to take any action to restrain, enjoin or otherwise delay any registration pursuant to Section 6.2 hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement. 6.7 (a) To the extent permitted by law, the Company shall indemnify each Holder, each underwriter of the Registrable Securities and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which any registration that has 14. been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.6(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in the Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any such registration, qualification or compliance or based on 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, in light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated by the Securities Act applicable to the Company and relating to any action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each Holder, each underwriter of the Registrable Securities and each person controlling such Holder, for reasonable legal and other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder and stated to be specifically for use in preparation of such Registration Statement, prospectus; provided that the Company will not be liable in any such case where the claim, loss, damage or liability arises out of or is related to the failure of the Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the Registration Statement becomes effective or in the amended prospectus filed with the SEC pursuant to Rule 424(b) or in the prospectus subject to completion under Rule 434 of the Securities Act, which together meet the requirements of Section 10(a) of the Securities Act (the "FINAL PROSPECTUS"), such indemnity shall not inure to the benefit of any such Holder, any such underwriter or any such controlling person, if a copy of the Final Prospectus furnished by the Company to the Holder for delivery was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and the Final Prospectus would have cured the defect giving rise to such loss, liability, claim or damage. (b) Each Holder will severally, if Registrable Securities held by such Holder are included in the securities as to which such registration is being effected, indemnify the Company, each of its directors and officers, each underwriter of the Registrable Securities and each person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.6(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in the Registration Statement, prospectus, or any amendment or supplement thereof, incident to any such registration, or based on 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, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers, each underwriter of the Registrable Securities and each person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such 15. claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Holder and stated to be specifically for use in preparation of the Registration Statement, prospectus; provided that the indemnity shall not apply to the extent that such claim, loss, damage or liability results from the fact that a current copy of the prospectus was not made available to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and the Final Prospectus would have cured the defect giving rise to such loss, claim, damage or liability. Notwithstanding the foregoing, (x) a Holder's aggregate liability pursuant to this subsection (b) and subsection (d) shall be limited to the net amount received by the Holder from the sale of the Registrable Securities and (y) the Holder shall not be liable to the Company for any consequential damages, including lost profits, solely with respect to losses, claims, damages, liabilities or expenses to which the Company (or any officer, director or controlling person as set forth above) may become subject (under the Securities Act or otherwise), arising out of, or based upon, any failure to comply with the covenants and agreements concerning its sale or other disposition of the Registrable Securities. (c) Each party entitled to indemnification under this Section 6.6 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such Indemnified Party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent will not be unreasonably withheld). No Indemnifying Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement 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) If the indemnification provided for in this Section 6.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties' relative intent, 16. knowledge, access to information and opportunity to correct or prevent such statement or omission. 6.8 (a) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Securities so that, as thereafter delivered to the Holders, such prospectus shall not contain an 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 not misleading, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 6.2 until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. (b) Each Holder shall suspend, upon request of the Company, any disposition of Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 6.2 during (i) any period not to exceed two 90-day periods within any one 12-month period the Company requires in connection with a primary underwritten offering of equity securities and (ii) any period, not to exceed one 45-day period per circumstance or development, when the Company determines in good faith that offers and sales pursuant thereto should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the disclosure that would be required in such a prospectus is premature or would have an adverse effect on the Company. (c) As a condition to the inclusion of its Registrable Securities, each Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may request in writing, including completing a Registration Statement Questionnaire in the form provided by the Company, or as shall be required in connection with any registration referred to in this Article 6. (d) Each Holder hereby covenants with the Company (i) not to make any sale of the Registrable Securities without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied, and (ii) if such Registrable Securities are to be sold by any method or in any transaction other than on a national securities exchange, Nasdaq or in the over-the-counter market, in privately negotiated transactions, or in a combination of such methods, to notify the Company at least five business days prior to the date on which the Holder first offers to sell any such Registrable Securities. (e) Each Holder acknowledges and agrees that the Registrable Securities sold pursuant to the Registration Statement are not transferable on the books of the Company unless the stock certificate submitted to the transfer agent evidencing such Registrable Securities is accompanied by a certificate reasonably satisfactory to the Company to the effect that (i) the Registrable Securities have been sold in accordance with such Registration Statement and (ii) the requirement of delivering a current prospectus has been satisfied. 17. (f) Each Holder agrees not to take any action with respect to any distribution deemed to be made pursuant to such Registration Statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law. (g) At the end of the Registration Period the Holders shall discontinue sales of shares pursuant to such Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such Registration Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company. 6.9 With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which at any time permit the sale of the Registrable Securities to the public without registration, so long as the Holders still own Registrable Securities, the Company shall use its reasonable best efforts to: (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times; (b) file with the SEC in a timely manner all reports and other documents required of the Company under the Exchange Act; and (c) so long as a Holder owns any Registrable Securities, furnish to such Holder, upon any reasonable request, a written statement by the Company as to its compliance with Rule 144 under the Securities Act, and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing a Holder to sell any such securities without registration. 6.10 The rights to cause the Company to register Registrable Securities granted to the Holders by the Company under Section 6.1 may be assigned in full by a Holder in connection with a transfer by such Holder of its Registrable Securities, provided, however, that such transfer must be made at least ten days prior to the Filing Date and that (i) such transfer may otherwise be effected in accordance with applicable securities laws; (ii) such Holder gives prior written notice to the Company at least ten days prior to the Filing Date; and (iii) such transferee agrees to comply with the terms and provisions of this Agreement, and such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 6.9, the rights of a Holder with respect to Registrable Securities as set out herein shall not be transferable to any other Person, and any attempted transfer shall cause all rights of such Holder therein to be forfeited. 6.11 With the written consent of the Company and the Holders holding at least a majority of the Registrable Securities that are then outstanding, any provision of this Article 6 may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended. Upon the effectuation of each such waiver or amendment, the Company shall promptly give written notice thereof to the Holders, if any, who have not previously received notice thereof or consented thereto in writing. 18. ARTICLE 7 INDEMNIFICATION In consideration of Purchaser's execution and delivery of this Agreement and its acquisition of the Units hereunder, and in addition to all of the Company's other obligations under this Agreement, the Company will indemnify and hold harmless Purchaser and each other holder of the Units and all of their stockholders, officers, directors, employees and direct or indirect Purchasers and any of the foregoing person's agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the "INDEMNITEES") from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (regardless of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys' fees and disbursements (the "INDEMNIFIED LIABILITIES"), incurred by an Indemnitee as a result of, or arising out of, or relating to (a) any breach of any representation or warranty made by the Company in Section 3 of this Agreement (b) any breach of any covenant, agreement or obligation of the Company contained in Section 4 of this Agreement or (c) any cause of action, suit or claim brought against such Indemnitee and arising out of or resulting from the execution, delivery, performance, breach or enforcement of this Agreement by the Company. To the extent that the foregoing undertaking by the Company is unenforceable for any reason, the Company will make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.
