     2.2. Reserved.

     2.3. Obligations of the Company. The Company will use commercially reasonable efforts to effect the registration of the Registrable Securities, and pursuant thereto the Company shall, as expeditiously as reasonably possible:

     (a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective and keep such registration statement effective until the latter to occur of (i) the expiration of six months or, if earlier, such time that the distribution contemplated by the registration statement has been completed or (ii) such

time that the Registrable Securities may be resold by the Holder without restriction under Rule 144 (assuming that such Registrable Securities that consist of securities convertible into other securities of the Company are exercised solely in exchange for other securities (including Common Stock) of the Company as contemplated by Rule 144(d)(3)(ii));

     (b) prepare and file with the SEC such amendments and supplements to such registration statement, and the prospectus used in connection with such registration statement, as may be necessary to comply with the 1933 Act in order to enable the disposition of all securities covered by such registration statement;

     (c) provide copies to and permit counsel designated by the Investors, if any, in the selling Stockholder questionnaire attached hereto as Exhibit B (the “Selling Stockholder Questionnaire”) to review such registration statement and all amendments and supplements thereto no fewer than seven days prior to their filing with the SEC and not file any document to which such counsel reasonably objects;

     (d) furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus, as required by the 1933 Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities;

     (e) use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders; provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the 1933 Act;

     (f) use its commercially reasonable efforts to cause all such Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed;

     (g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

     (h) promptly make available for inspection by the selling Holders and any attorney or accountant or other agent retained by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; and

     (i) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed.

     2.4. Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities, including, without limitation the information required by Exhibit B.

     2.5. Expenses of Registration. All expenses incurred in connection with registrations, filings, or qualifications pursuant to Section 2, including all registration, filing, and qualification fees; printers’ and accounting fees; and fees and disbursements of counsel for the Company, shall be borne and paid by the Company. All selling expenses relating to Registrable Securities registered pursuant to Section 2 shall be borne and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf. Notwithstanding the foregoing, upon the registration of Registrable Securities pursuant to Section 2, Holders of a majority of the Registrable Securities that are to be registered pursuant to Section 2 shall be entitled to appoint one counsel in connection with the registration, and the Company shall pay such counsel’s fees and disbursements related to the registration in an amount not to exceed $10,000.

     2.6. Indemnification. If any Registrable Securities are included in a registration statement under this Section 2:

     (a) To the extent permitted by law, the Company will indemnify and hold harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the 1933 Act) for each such Holder; and each Person, if any, who controls such Holder or underwriter within the meaning of the 1933 Act or the 1934 Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling Person, or other aforementioned Person expressly for use in connection with such registration.

     (b) To the extent permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the registration statement, each Person (if any), who controls the Company within the meaning of the 1933 Act, legal counsel and accountants for the

Company, any underwriter (as defined in the 1933 Act), any other Holder selling securities in such registration statement, and any controlling Person of any such underwriter or other Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay, severally and not jointly, to the Company and each other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 2.6(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld.

     (c) Promptly after receipt by an indemnified party under this Section 2.6 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.6 give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflicting interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the indemnified party under this Section 2.6 unless such failure actually and materially prejudices the indemnifying party’s ability to defend such action.

     (d) Notwithstanding anything else herein to the contrary, the foregoing indemnity agreements of the Company and the selling Holders are subject to the condition that, insofar as they relate to any Damages arising from any untrue statement or alleged untrue statement of a material fact contained in, or omission or alleged omission of a material fact from, a preliminary prospectus (or necessary to make the statements therein not misleading) that has been corrected in the form of prospectus included in the registration statement at the time it becomes effective, or any amendment or supplement thereto filed with the SEC pursuant to Rule 424(b) under the 1933 Act (the “Final Prospectus”), such indemnity agreement shall not inure to the benefit of any Person if a copy of the Final Prospectus was furnished to the indemnified party and such indemnified party failed to deliver, at or before the confirmation of the sale of the shares registered in such offering, a copy of the Final Prospectus to the Person asserting the loss, liability, claim, or damage in any case in which such delivery was required by the 1933 Act.

     (e) To provide for just and equitable contribution to joint liability under the 1933 Act in any case in which either (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 2.6 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Section 2.6 provides for indemnification in such case, or (ii) contribution under the 1933 Act may be required on the part of any party hereto for which indemnification is provided under this Section 2.6, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect 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 allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case, no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

     (f) the obligations of the Company and Holders under this Section 2.6 shall survive the completion of any offering of Registrable Securities in a registration under Section 2, and otherwise shall survive the termination of this Agreement.

     2.7. Current Public Information. With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration, the Company shall:

     (a) make and keep available adequate current public information, as those terms are understood and defined in Rule 144, at all times; and

     (b) furnish to any Holder, so long as the Holder owns any Registrable Securities, upon request (A) to the extent accurate, a written statement by the Company that it has complied with the reporting requirements of Rule 144; (B) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company; and (C) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration.

     2.8. Obligations of the Investors.

     (a) Each Investor shall furnish to the Company a Selling Stockholder Questionnaire and shall furnish in writing to the Company such additional information

regarding itself, the Registrable Securities held by it, and the intended method of disposition of the Registrable Securities held by it, as shall be reasonably required to effect the registration of such Registrable Securities, and shall execute such documents in connection with such registration as the Company may reasonably request. At least twenty one Business Days prior to the first anticipated filing date of a registration statement, the Company shall notify the Investors of the information the Company requires from the Investors, to the extent not included in the Selling Stockholder Questionnaire, if the Investors elect to have any of the Registrable Securities included in the registration statement. The Investors shall provide such information to the Company at least fifteen Business Days prior to the first anticipated filing date of such registration statement.

     (b) The Investors, by their acceptance of the Registrable Securities, agree to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of a registration statement hereunder.

     2.9. Termination of Registration Statement. The Company’s obligation to maintain the effectiveness of the registration statement filed pursuant to Section 2.1 shall terminate upon such time that the Registrable Securities may be resold by all Holders without restriction under Rule 144 (as amended from time to time).

Exhibit A

Plan of Distribution

     The selling stockholders, which as used herein includes donees, pledgees, transferees, or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution, or other transfer, may, from time to time, sell, transfer, or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market, or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

     The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

	•		ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
	•		block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
	•		purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
	•		an exchange distribution in accordance with the rules of the applicable exchange;
	•		privately negotiated transactions;
	•		short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the SEC;
	•		through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
	•		broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
	•		a combination of any such methods of sale; and
	•		any other method permitted by applicable law.

     The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledges, or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

     In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

     The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

     The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, as amended, provided that they meet the criteria and conform to the requirements of that rule.

     Any underwriters, broker-dealers, or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the

Securities Act. Any discounts, commissions, concessions, or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act.

     To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer, or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

     In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

     We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates.
