The Investor (also referred to hereinafter as the "Holder") shall pay any and all underwriting commissions, if any, in connection with the registration and sale of the Securities under this Section 4.3, but the Company shall bear all fees and expenses attendant to registering the Securities under federal, state and any other securities laws, and any required filings with the NASD, including, without limitation, all printing costs.


(iv) The Company shall use its best efforts through its officers, directors, auditors, and counsel to cause such registration statement to become effective as promptly as practicable.


(v) The Company shall use its best efforts to cause the Securities to be registered or qualified for sale under the securities or blue sky laws of such jurisdictions as the Holder may reasonably request; provided, however, that the Company shall not by reason of this Section 4.3 be required to qualify to do business in any state in which it is not otherwise required to qualify to do business or to file a general consent to service of process in such jurisdiction.


(vi) Upon request, the Company shall furnish the Holder and its counsel copies of all registration statements and amendments and supplements thereto, each preliminary and final prospectus and amendment and supplement thereto, comment letters from the SEC, the National Association of Securities Dealers ("NASD") and state securities commissions, and such other documents as the Investor shall reasonably request to facilitate the disposition of the Securities included in such registration.

amended and supplemented) 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, or any violation by the Company of any rule or regulation promulgated under the Act or any state securities or blue sky laws applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will promptly reimburse the Holder, and each partner, officer, director, and each controlling person of the Holder, for any legal and other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided, that the Company will not be liable to the Holder or any partner, officer, director and controlling person of the Holder, to the extent that any such claim, loss, dam age, liability or expense arises out of or is based on any untrue statement or omission contained in information furnished to the Company by the Holder in writing for use therein.





(viii) In connection with any registration statement in which the Holder is participating, the Holder shall furnish to the Company in writing such information and affidavits as the Company and any underwriter reasonably requests for use in connection with any such registration statement or prospectus and shall indemnify the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by the Holder.


(ix) If the indemnification provided for in subparagraph (vi) above 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 hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such of loss, liability, claim, damage, 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 that 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 a court of competent jurisdiction 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 party's relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.


(x) With a view to making available the benefits of certain rules and regulations of the SEC which may permit the sale of restricted securities (as that term is used in Rule 144 under the Act) to the public without registration, the Company undertakes to use its best efforts to:

(ix) Notwithstanding the forgoing, if at any time or from time to time after the date of effectiveness of the Registration Statement, the Company notifies the Holder in writing of the existence of a Potential Material Event, the Holder shall not offer or sell any Securities, or engage in any other transaction involving or relating to the Securities, from the time of the giving of notice with respect to a Potential Material Event until either the events or circumstances comprising such Potential Material Event have been disclosed to the public or no longer constitute a Potential Material Event; provided however, that the Company may not so suspend the right to the Holder during the periods the Registration Statement is required to be in effect other than during a Permitted Suspension Period. The term "Permitted Suspension Period" means one or more suspension periods during any consecutive 12-month period and the term "Potential Material Even t" shall mean any of the following: (i) the possession by the Company of material information not ripe for disclosure in a registration statement, which shall be evidenced by determinations in good faith by the Board of Directors of the Company that disclosure of such information in the registration statement would be detrimental to the business and affairs of the Company; or (ii) any material engagement or activity by the Company which would, in the good faith determination of the Board of Directors of the Company, be adversely affected by disclosure in a registration statement at such time, which determination shall be accompanied by a good faith determination. Notwithstanding anything to the contrary contained herein, the provisions hereof shall not apply to the extent that any of the Securities then included in such Registration Statement may be sold or otherwise transferred under Rule 144 under the Act or are transferred in a private non-brokerage transaction.
