1.2 Registration.

(a) Registration Requirement. The Company shall file with the Commission a Shelf Registration Statement meeting the requirements of the Securities Act within thirty (30) days following the Closing, and will use its best efforts to cause the Shelf Registration Statement to be declared effective by the Commission as soon as reasonably practicable thereafter and in any event not later than seventy-five (75) days after the Closing. Each Holder agrees to furnish to the Company all information with respect to such Holder necessary to make the information set forth in the Shelf Registration Statement or Prospectus not materially misleading.

(b) Effectiveness Requirement. The Company agrees to use its best efforts to keep the Shelf Registration Statement continuously effective and the Prospectus usable for resales for a period commencing on the date that such Shelf Registration Statement is initially declared effective by the Commission and terminating on the date when all of the Registrable Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement or cease to be Registrable Securities (the “Effectiveness Period’); provided, however, the Company is permitted to suspend sales of the Registrable Securities during any Delay Period. The Company will be deemed not to have used its best efforts to cause the Shelf Registration Statement to become, or to remain, effective during the requisite period if it voluntarily takes any action or omits to take any action that would result in the Shelf Registration Statement not being declared effective or that would result in the Holders of Registrable Securities covered thereby not being able to offer and sell such Registrable Securities during that period, unless such action or omission is required by applicable law and except during any Delay Period.

(c) Delay Period. The term “Delay Period” means, with respect to any obligation to keep any Shelf Registration Statement or Prospectus usable for resales pursuant to this Section 1.2, the shortest period of time determined in good faith by the Company’s Board of Directors to be necessary for such purpose when there exist circumstances relating to a material pending development, including, but not limited to, a pending or contemplated material acquisition or merger or other material transaction or similar event, which would require disclosure by the Company in such Shelf Registration Statement or Prospectus of material information which the Company determines in good faith upon the advice of its counsel that it has a bona fide business purpose for keeping confidential and non-public and the non-disclosure of which in such Shelf Registration Statement or Prospectus might cause such Shelf Registration Statement or Prospectus to fail to comply with applicable disclosure requirements. A Delay Period shall commence on and include the date that the Company gives written notice (a “Delay Notice”) to the Holders that the Prospectus is no longer usable as a result of a material pending development and shall end on the date when the Holders are advised in writing by the Company that the current Delay Period has terminated (it being understood that the Company shall give such notice to all Holders promptly upon making the determination that the Delay Period has ended); provided, however, and notwithstanding anything herein to the contrary the Company is only entitled to three (3) Delay Periods having durations of not more than thirty (30) days each during any consecutive 12 month period, and not to exceed more than seventy-five (75) days in the aggregate in any consecutive 12 month period. The Company covenants and agrees that it will not deliver a Delay Notice with respect to a Delay Period unless Company employees, officers and directors and their Affiliates and any other holders of registration rights with respect to the Company’s Common Stock are also prohibited by the Company for the duration of such Delay Period from effecting any public sales of shares of Common Stock or Preferred Stock beneficially owned by them. The Company represents that it has no knowledge of any circumstance that would reasonably be expected at the time of the effectiveness of the Shelf Registration Statement pursuant to Section 1.2(a) to cause the Company to exercise its rights under this Section 1.2(c). Without limiting any of the foregoing, but for the purpose of additional clarity, the Company shall not commence any Delay Period until after the Shelf Registration Statement is filed with the Commission.

(d) Notice. The Company will, in the event a Shelf Registration Statement is declared effective, provide to each Holder a reasonable number of copies of the Prospectus which is a part of such Shelf

Registration Statement, notify each such Holder when such Shelf Registration Statement has become effective and take such other actions as are required to permit unrestricted resales of the Registrable Securities. The Company further agrees to supplement or amend each Shelf Registration Statement if and as required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder for shelf registrations, and the Company agrees to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the Commission.

(e) Liquidated Damages. If the Shelf Registration Statement is not effective by the ninetieth (90^th) day after the Closing, then the Company will pay to each Holder as liquidated damages and not a penalty, an amount in cash equal to 1.0% of the amount invested by each such Holder for each month or part thereof that such Shelf Registration Statement is not so effective, payable in weekly installments. If a stop order, injunction or other order or requirement of the Commission or any other governmental agency or court is imposed or if for any other reason the effectiveness of the Shelf Registration Statement is suspended, then the Company shall pay liquidated damages to each Holder, as liquidated damages and not a penalty, an amount in cash equal to 1.0% of the amount invested by each such Holder for each month or part thereof that such Shelf Registration Statement is not so effective, payable in weekly installments. Notwithstanding the preceding sentence, the Holders will not be entitled to receive liquidated damages under this Section 1.2(e) during a Delay Period (subject to the duration restrictions in Section 1.2(c)). Liquidated damages shall be deemed to commence accruing on the day on which the event triggering such liquidated damages occurs. The liquidated damages to be paid to the Holders pursuant to this Section 1.2(e) shall cease to accrue (i) with respect to the liquidated damages for failure to have the Shelf Registration Statement declared effective on or prior to the ninetieth (90^th) day after the Closing, on the day after the Holders have received notice from the Company that the Shelf Registration Statement is declared effective, or (ii) with respect to the liquidated damages for the suspension of effectiveness of the Shelf Registration Statement, on the day after the Holders have received notice from the Company regarding the reinstatement of effectiveness of the Shelf Registration Statement. The Company shall pay the liquidated damages due under this section at the end of each week during which such damages accrue and, to the extent such liquidated damages are not paid when due, shall thereafter accrue interest at a rate equal to the U.S. prime rate plus the lesser of (i) 3.0% per annum and (ii) the maximum amount permitted by law. Liquidated damages shall be paid to the Holders by wire transfer in immediately available funds to the accounts designated by the Holders. The parties hereto agree that the liquidated damages provided for in this Section 1.2(e) constitute a reasonable estimate of the damages that will be suffered by the Holders by reason of the failure of the Shelf Registration Statement to be declared effective and/or to remain effective, as the case may be, in accordance with this Agreement.

director, agent, affiliate and employee of each Holder, underwriter and controlling Person, against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal, state or provincial law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such Shelf Registration Statement, including any preliminary Prospectus or final Prospectus contained therein, any document incorporated by reference in such Shelf Registration Statement or any amendments or supplements thereto, (ii) the 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 (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation. promulgated under the Securities Act, the Exchange Act or any state or provincial securities law directly related to, or in connection with, the Shelf Registration Statement or the related offering; and the Company will pay to a Holder, underwriter or controlling Person or officer, director, agent, affiliate or employee of a Holder, underwriter or controlling Person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 1.4(a) does not apply to (x) amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company, which consent may not be unreasonably withheld, conditioned or delayed; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in a Shelf Registration Statement or final Prospectus or any amendment or supplement thereto or any related preliminary Prospectus, in reliance upon and in conformity with written information furnished to the Company by the Holder specifically for inclusion therein or (y) any untrue statement or alleged untrue statement of material fact or omission or alleged omission to state therein a material fact in any preliminary Prospectus, if a copy of the final Prospectus in which such untrue statement or alleged untrue statement or omission or alleged omission was corrected was required to be sent or given but had not been sent or given to such person prior to the settlement of the sale, so long as the final Prospectus and any amendments or supplements thereto were provided by the Company to the Indemnified Holder in the requisite quantity and on a timely basis to permit proper delivery on or prior to the settlement of the sale. The Company shall notify the Holders promptly of the institution, threat or assertion of any action, claim, suit, investigation or proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.

(b) To the fullest extent permitted by law, each Holder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors, officers, employees and Affiliates, each Person, if any, who controls the Company within the meaning of the Securities Act, any underwriter, any other stockholder selling securities in such Shelf Registration Statement and any controlling Person of any such underwriter or other stockholder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing Persons may become subject, under the Securities Act, the Exchange Act or other federal, state or provincial law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in such Shelf Registration Statement, including any preliminary Prospectus or final Prospectus contained therein or any amendments or supplements thereto; and such Holder will pay, as incurred, any legal or other expenses reasonably incurred by any Person intended to be indemnified pursuant to this Section 1.4(b), in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 1.4(b) does not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such Holder, which consent may not be unreasonably withheld, conditioned or delayed; and further provided, that, in no event will any indemnity under this Section 1.4(b) exceed the net proceeds received by such Holder from the sale of Registrable Securities giving rise to such indemnification obligation.

(c) Promptly after receipt by an indemnified party under this Section 1.4 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.4, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party will have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof, including the employment of counsel reasonably satisfactory to the indemnified party, if (i) the indemnifying party acknowledges its obligation to indemnify the indemnified party for any losses, damages or liabilities resulting from such claim and provide reasonable evidence to the indemnified party of its financial ability to satisfy such obligation; (ii) the claim does not seek to impose any liability or obligation on the indemnified party other than for money damages; and (iii) the claim does not relate to the indemnified party’s relationship with its customers or employees. An indemnified party shall have the right to employ separate counsel in any such action, claim, suit, investigation or 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: (1) the indemnifying party has agreed in writing to pay such fees and expenses; (2) the indemnifying party shall have failed promptly to assume the defense of such action, claim, suit, investigation or proceeding and to employ counsel reasonably satisfactory to such indemnified party in any such action, claim, suit, investigation or proceeding; (3) the indemnifying party is not entitled to assume and control the defense of any such action, claim, suit, investigation or proceeding pursuant to clauses (ii) or (iii) of the immediately preceding sentence; or (4) such indemnified party shall have been advised 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 the reasonable fees and expenses of one separate counsel for all indemnified parties shall be at the expense of the indemnifying party).The indemnifying party will not be liable for any settlement of any action, claim, suit, investigation or proceeding effected without its consent, which consent may not be unreasonably withheld, conditioned or delayed. No indemnifying party shall, without the prior written consent of the 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 an unconditional release from all liability in respect of such claim or litigation. The failure by the indemnified party to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any obligation or liability to the indemnified party under this Section 1.4, except (and only) to the extent that such failure shall have prejudiced the indemnifying party.

(d) If the indemnification provided for in this Section 1.4 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, will 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 that resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations; provided, that, in no event will any contribution by a Holder under this Section 1.4(d) exceed the net proceeds received by a Holder from the sale of Registrable Securities giving rise to such indemnification obligation. The relative fault of the indemnifying party and of the indemnified party will 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, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 1.4(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 sentence. 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 amount paid or payable by a party as a result of any loss, liability, claim, damage or expense shall be deemed to include, subject to the limitations set forth in Section 1.4(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any action, claim, suit, investigation or 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.

(e) The obligations of the Company and Holders under this Section 1.4 will survive the completion of any offering of Registrable Securities in the Shelf Registration Statement under this Section 1 and otherwise.

1.5 Reports Under the Exchange Act.

(a) The Company shall file as and when applicable, on a timely basis, all reports required to be filed by it under the Exchange Act. If the Company is not required to file reports pursuant to the Exchange Act, upon the request of any Holder of Registrable Securities, the Company shall make publicly available the information specified in subparagraph (c)(2) of Rule 144. The Company shall take such further action as may be reasonably required from time to time and as may be within the reasonable control of the Company, to enable the Holders to Transfer Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 or any other exemption from registration. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements and, if not, the specifics thereof.

(b) In connection with any sale, transfer or other disposition by a Holder of any Registrable Securities pursuant to Rule 144, the Company shall cooperate with such Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any Securities Act legend, and enable certificates for such Registrable Securities to be for such number of shares and registered in such names as the Holder may reasonably request at least two (2) business days prior to any sale of Registrable Securities.

(c) So long as the Shelf Registration Statement is effective covering the resale of Registrable Securities owned by a Holder, the Company will furnish to such Holder: (i) as soon as practicable after it is available, one copy of (1) its Annual Report to Stockholders (which Annual Report shall contain financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants), (2) its Annual Report on Form 10-K and (3) its Quarterly Reports on Form 10-Q (the foregoing, in each case, excluding exhibits); and (ii) upon the request of the Holder, all exhibits excluded by the parenthetical to clause (i) of this Section 1.5(c) as filed with the SEC and all other information that is made available to shareholders.

1.6 Registration Expenses. The Company shall bear and pay all expenses incurred in connection with any registration, filing, or qualification of Registrable Securities with respect to a Shelf Registration Statement for each selling Holder, including all registration, exchange listing, accounting, filing and NASD fees, all fees and expenses of complying with securities or blue sky laws, all word processing, duplicating and printing expenses, messenger and delivery expenses, the reasonable fees and disbursements of counsel for the Company, and of the Company’s independent public accountants, including the expenses of “comfort letters” required by or incident to such performance and compliance and reasonable fees and disbursements of one firm of counsel and one firm of accountants for the Holders. Holders shall be responsible for any underwriting discounts and commissions and taxes of any kind (including without limitation, transfer taxes) relating to any disposition, sale or transfer of Registrable Securities.

1.7 Piggy-Back Registrations; Other Registrations. Subject to the terms of the Company’s existing registration rights agreements in effect prior to the date hereof, if at any time during the Effectiveness Period there is not an effective Shelf Registration Statement covering all of the Registrable Securities and the Company

shall determine to 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, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the stock option or other employee benefit plans, then the Company shall send to each Holder a written notice of such determination and, if within fifteen days after the date of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered, subject to customary underwriter cutbacks applicable to all holders of registration rights. The Company agrees that it will not grant to any person any registration rights that are senior to the rights granted in Section 1 of this Agreement. In no event at any time before the Shelf Registration Statement becomes effective with respect to the Shares shall the Company publicly announce or file any other, registration statement, other than registrations on Form S-8 without the consent of the Holders of a majority of the Registrable Securities.

1.8 Future Offerings. If the Company proposes to effect any private offering of its Common Stock or other securities convertible into or exercisable or exchangeable for shares of its Common Stock (other than (i) shares of Common Stock and stock options issued pursuant to the Company’s 2003 Management Equity Incentive Plan, (ii) shares of Common Stock issued pursuant to warrants outstanding pursuant to a Secured Lender Warrant Agreement, dated as of December 12, 2003, (iii) shares of Common Stock issued pursuant to warrants outstanding pursuant to a Senior Discount Warrant Agreement, dated as of December 12, 2003, (iv) shares of Common Stock issuable upon conversion of a promissory note issued to Xxxxxxxx Xxxxx Xxxxxx & Xxxxx, and (v) shares of Common Stock and options issued pursuant to the Company’s 2003 Directors Equity Incentive Plan) prior to the first anniversary of the date of this Agreement, the Company shall notify each Holder in writing of such offering at least five business days prior to the consummation thereof and the Holders will be permitted to participate in such offering on the same terms and conditions applicable to the other investors participating in the offering. If the number of shares subscribed for by the Holders and the other investors participating in such offering exceeds the number of shares the Company proposes to sell in the offering, the shares will be prorated among the Holders and such other investors on the basis of the number of shares subscribed for by each party.

1.9 Assignment of Rights.

(a) Except as expressly provided in this Section 1.9, the rights of the parties hereto cannot be assigned and any purported assignment or transfer to the contrary shall be void ab initio. So long as the terms of this Section 1.9 are followed, any Holder may assign any of its rights under this Agreement, without the consent of the Company, to any Person, including, without limitation, an Affiliate of such Holder, to whom such Holder Transfers any Registrable Securities or any rights to acquire Registrable Securities so long as such Transfer is not made pursuant to an effective Registration Statement or pursuant to Rule 144 or Rule 145 (or any successor provisions) or in any other manner the effect of which is to cause the Transferred securities to be freely transferable without regard to the volume and manner of sale limitations set forth in Rule 144 (or any successor provision) in the hands of the transferee as of the date of such Transfer.

(b) The nature and extent of any rights assigned shall be as agreed to between the assigning party and the assignee. No Person may be assigned any rights under this Agreement unless (i) the Company is given written notice by the assigning party at the time of such assignment stating the name and address of the assignee and identifying the securities of the Company as to which the rights in question are being assigned, (ii) such assignment is exempt from the registration requirements of the Securities Act, and (iii) and the assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including, without limitation, the provisions of this Section 1.9.

Exhibit A

Plan of Distribution

The selling securityholders, or their pledgees, donees, transferees, or any of their successors in interest selling shares received from a named selling securityholder as a gift, partnership distribution or other non-sale-related transfer after the date of this prospectus (all of whom may be selling securityholders), may sell the securities from time to time on any stock exchange or automated interdealer quotation system on which the securities are listed, in the over-the-counter market, in privately negotiated transactions or otherwise, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at prices otherwise negotiated. The selling securityholders may sell the securities by one or more of the following methods, without limitation:

(a) block trades in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

(b) purchases by a broker or dealer as principal and resale by the broker or dealer for its own account pursuant to this prospectus;

(d) ordinary brokerage transactions and transactions in which the broker solicits purchases;

(e) privately negotiated transactions;

(f) short sales;

(g) through the writing of options on the securities, whether or not the options are listed on an options exchange;

(h) through the distribution of the securities by any selling securityholder to its partners, members or stockholders;

(i) one or more underwritten offerings on a firm commitment or best efforts basis; and

(j) any combination of any of these methods of sale.

The selling securityholders may also transfer the securities by gift. We do not know of any arrangements by the selling securityholders for the sale of any of the securities.

The selling securityholders may engage brokers and dealers, and any brokers or dealers may arrange for other brokers or dealers to participate in effecting sales of the securities. These brokers, dealers or underwriters may act as principals, or as an agent of a selling securityholder. Broker-dealers may agree with a selling securityholder to sell a specified number of the securities at a stipulated price per security. If the broker-dealer is unable to sell securities acting as agent for a selling securityholder, it may purchase as principal any unsold securities at the stipulated price. Broker-dealers who acquire securities as principals may thereafter resell the securities from time to time in transactions in any stock exchange or automated interdealer quotation system on which the securities are then listed, at prices and on terms then prevailing at the time of sale, at prices related to the then-current market price or in negotiated transactions. Broker-dealers may use block transactions and sales to and through broker-dealers, including transactions of the nature described above. The selling securityholders may also sell the securities in accordance with Rule 144 under the Securities Act of 1933, as amended, rather than pursuant to this prospectus, regardless of whether the securities are covered by this prospectus.

From time to time, one or more of the selling securityholders may pledge, hypothecate or grant a security interest in some or all of the securities owned by them. The pledgees, secured parties or persons to whom the

securities have been hypothecated will, upon foreclosure in the event of default, be deemed to be selling securityholders. As and when a selling securityholder takes such actions, the number of securities offered under this prospectus on behalf of such selling securityholder will decrease. The plan of distribution for that selling securityholder’s securities will otherwise remain unchanged. In addition, a selling securityholder may, from time to time, sell the securities short, and, in those instances, this prospectus may be delivered in connection with the short sales and the securities offered under this prospectus may be used to cover short sales.

To the extent required under the Securities Act of 1933, the aggregate amount of selling securityholders’ securities being offered and the terms of the offering, the names of any agents, brokers, dealers or underwriters and any applicable commission with respect to a particular offer will be set forth in an accompanying prospectus supplement. Any underwriters, dealers, brokers or agents participating in the distribution of the securities may receive compensation in the form of underwriting discounts, concessions, commissions or fees from a selling securityholder and/or purchasers of selling securityholders’ securities of securities, for whom they may act (which compensation as to a particular broker-dealer might be in excess of customary commissions).

The selling securityholders and any underwriters, brokers, dealers or agents that participate in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, and any discounts, concessions, commissions or fees received by them and any profit on the resale of the securities sold by them may be deemed to be underwriting discounts and commissions.

A selling securityholder may enter into hedging transactions with broker-dealers and the broker-dealers may engage in short sales of the securities in the course of hedging the positions they assume with that selling securityholder, including, without limitation, in connection with distributions of the securities by those broker-dealers. A selling securityholder may enter into option or other transactions with broker-dealers that involve the delivery of the securities offered hereby to the broker-dealers, who may then resell or otherwise transfer those securities. A selling securityholder may also loan or pledge the securities offered hereby to a broker-dealer and the broker-dealer may sell the securities offered hereby so loaned or upon a default may sell or otherwise transfer the pledged securities offered hereby.

The selling securityholders and other persons participating in the sale or distribution of the securities will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including Regulation M. This regulation may limit the timing of purchases and sales of any of the securities by the selling securityholders and any other person. The anti-manipulation rules under the Securities Exchange Act of 1934 may apply to sales of securities in the market and to the activities of the selling securityholders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities with respect to the particular securities being distributed for a period of up to five business days before the distribution. These restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.

We have agreed to indemnify in certain circumstances the selling securityholders and any brokers, dealers and agents who may be deemed to be underwriters, if any, of the securities covered by the registration statement, against certain liabilities, including liabilities under the Securities Act of 1933. The selling securityholders have agreed to indemnify us in certain circumstances against certain liabilities, including liabilities under the Securities Act of 1933, as amended.

The securities offered hereby were originally issued to the selling securityholders pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended. We agreed to register the securities under the Securities Act of 1933, and to keep the registration statement of which this prospectus is a part effective until the date on which the selling securityholders have sold all of the securities. We have agreed to pay all expenses in connection with this offering, including the fees and expenses of counsel or other advisors to the selling securityholders, but not including underwriting discounts, concessions, commissions or fees of the selling securityholders.

We will not receive any proceeds from sales of any securities by the selling securityholders.

We cannot assure you that the selling securityholders will sell all or any portion of the securities offered hereby.
