     This Registration Rights Agreement (the “Agreement”) is made as of the date set forth below between Quantum Fuel Systems Technologies Worldwide, Inc., a Delaware corporation (the “Company”), and the purchasers of its Common Stock (as defined below) pursuant to a Securities Purchase Agreement dated as of the date hereof (each in “Investor” and, collectively, the “Investors”). Capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Securities Purchase Agreement.

     WHEREAS, the Company has sold to up to 12,500,000 shares (the “Shares”) of its common stock, $0.001 par value per share, (the “Common Stock”), to certain investors in a private placement (the “Offering”); and

     WHEREAS, the execution and delivery of this Agreement by the Company is a condition to the completion of the Offering.

NOW, THEREFORE, the parties hereto agree as follows:

(“SEC”), within thirty (30) Calendar Days after the Closing Date (the “First Required Filing Date”), a Registration Statement on Form S-3 or such other form as is available to the Company to enable the resale by the Investors from time to time of the Shares, and any securities issued or issuable upon any stock split, dividend or other distribution, recapitalization or similar event with respect to the foregoing ("First Registration Statement”);

(ii) prepare and file with the Securities and Exchange Commission

(“SEC”), within ten (10) Calendar Days after the date that shareholder approval is obtained authorizing the Company to amend its Certificate of Incorporation for the purpose of increasing the number of the Company’s authorized shares of common stock (the “Second Required Filing Date”), a Registration Statement on Form S-3 or such other form as is available to the Company to enable the resale by the Investors from time to time of the Warrant Shares, and any securities issued or issuable upon any stock split, dividend or other distribution, recapitalization or similar event with respect to the foregoing (“Second Registration Statement”)

The First Registration Statement and the Second Registration Statement are sometimes hereinafter referred to collectively as Registration Statements. The securities to be registered on the Registration Statements are collectively, the “Registrable Securities”;

     (b) use its best efforts, subject to receipt of necessary information from the Investors, to cause the First Registration Statement and Second Registration Statement to become effective as soon as possible, but in no event shall the First Registration Statement become effective later than ninety (90) days following the Closing Date and shall the Second Registration Statement become effective later than ninety (90) days following the Second Required Filing Date (each a “Required Effective Date”). If the First Registration Statement and/or the Second Registration Statement (i) has not been filed by the First Required Filing Date or the Second Required Filing Date, as applicable, or (ii) has

{33164\10\DT262983.DOC;1}

not been declared effective by the SEC on or before its Required Effective Date, then the Company shall, immediately following the First Required Filing Date or Second Required Filing Date, as applicable, (if not then so filed) and the applicable Required Effective Date (if not then so effective), and on each 30^th day anniversary thereafter, make a payment to the Investor as compensation for such delay (the “Late Registration Payments”) an amount equal to one percent (1%) of the Purchase Price paid for the Shares purchased by the Investor, until the Registration Statement is filed or declared effective by the SEC. Notwithstanding the foregoing, in no event shall the total of all Late Registration Payments exceed in the aggregate twelve percent (12%) of such Purchase Price. Late Registration Payments, if any, will be prorated on a daily basis and will be paid to Investor by wire transfer or check within five (5) Business Days after the date that each payment is due. If the Company fails to pay any liquidated damages pursuant to this Section or Section 3(c) in full within seven days after the date payable, the Company will pay interest thereon at a rate of 12% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Investor, accruing daily from the date such liquidated damages are due until such amounts, plus all such interest thereon, are paid in full;

     (c) use its commercially reasonable best efforts to prepare and file with the SEC such amendments and supplements to the Registration Statement and the Prospectus as may be necessary to keep the Registration Statement current and effective for a period ending on the earlier of (i) the date on which the Investor may sell Registrable Securities pursuant to paragraph (k) of Rule 144 under the Securities Act or any successor rule (“Rule 144”) or (ii) such time as all Registrable Securities purchased by such Investor in this Offering have been sold pursuant to a registration statement or Rule 144 (the “Effectiveness Period”), and to notify each Investor promptly upon the Registration Statement and each post-effective amendment thereto, being declared effective by the SEC;

     (d) with a view to making available to the Investor the benefits of Rule 144 or other rule that may permit the Investor to sell Shares without registration, the Company agrees to use its commercially reasonable efforts to: (i) make and keep public information available, as those terms are understood and defined in Rule 144, until the earlier of (A) such date as all of the Investor’s Shares may be resold pursuant to Rule 144(k) or (B) such date as all of the Investor’s Shares shall have been sold; (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and under the Exchange Act; and (iii) furnish to the Investor upon request a written statement that the Company has complied with the reporting requirements of the Securities Act and the Exchange Act, a copy (in paper or electronic version) of the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be reasonably requested that permits the selling of any such Shares without registration.

     The Company understands that the Investor disclaims being an underwriter, but acknowledges that a determination by the SEC that the Investor is deemed an underwriter shall not relieve the Company of any obligations it has hereunder.

     (a) Not less than three Business Days prior to the filing of a Registration Statement or any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated or deemed to be incorporated therein by reference), the Company shall (i) furnish to the Investors and Investor 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 such Investors and Investor Counsel, and (ii) cause its officers and directors, counsel and

independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act.

     (b) (i) Prepare and file with the SEC 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 SEC 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 SEC with respect to the Registration Statement or any amendment thereto and as promptly as reasonably possible provide the Investors true and complete copies of all correspondence from and to the SEC 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 Investors thereof set forth in the Registration Statement as so amended or in such Prospectus as so supplemented.

     (c) Notify the Investors of Registrable Securities to be sold and Investor Counsel as promptly as reasonably possible, and (if requested by any such Person) confirm such notice in writing no later than one Business Day thereafter, of any of the following events: (i) the SEC notifies the Company whether there will be a “review” of any Registration Statement; (ii) the SEC comments in writing on any Registration Statement (in which case the Company shall deliver to each Investor 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 SEC 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 SEC 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 or incorporated by reference in any Registration Statement become ineligible for inclusion or incorporation 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 Investor and Investor 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 SEC.

     (f) Promptly deliver to each Investor and Investor 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.

     (i) Cooperate with the Investors 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 Investors may request.

     (j) Upon the occurrence of any event described in Section 2.1(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 Investors 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 Investor material, nonpublic information unless such Investor specifically requests in advance to receive material, nonpublic information in writing.

     (b) Indemnification by Investors. Each Investor 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 Investor 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 Investor furnished in writing to the Company by such Investor expressly for use therein, or to the extent that such information relates to such Investor or such Investor’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Investor 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 2.1(c)(v)-(vii), the use by such Investor of an outdated or defective Prospectus after the Company has notified such Investor in writing that the Prospectus is outdated or defective and prior to the receipt by such Investor of the Advice contemplated in Section 2.4. In no event shall the liability of any selling Investor hereunder be greater in amount than the dollar amount of the net proceeds received by such Investor 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 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). 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. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, 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 Business Days of written notice thereof to the Indemnifying Party (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 2.3(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 2.3(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 2.3(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 2.3(d), no Investor shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Investor from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Investor 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.

     2.4 Dispositions. Each Investor agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement. Each Investor further agrees that, upon receipt of a Suspension Notice or a notice from the Company of the occurrence of any event of the kind described in Sections 2.1(c)(v), (vi) or (vii), such Investor will discontinue disposition of such Registrable Securities under the Registration Statement until such Investor’s receipt of the copies of the supplemented Prospectus and/or amended Registration Statement contemplated by Section 2.1(j), or until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Company may provide appropriate stop orders to enforce the provisions of this paragraph.

     2.5 No Piggyback on Registrations. Except as set forth on Schedule 2.5, neither the Company nor any of its security holders (other than the Investors in such capacity pursuant hereto) may include securities of the Company in the Registration Statement other than the Registrable Securities, and the Company shall not after the date hereof enter into any agreement providing any such right to any of its security holders.

     2.6 Piggy-Back Registrations. If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the SEC 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 stock option or other employee benefit plans, then the Company shall send to each Investor written notice of such determination and if, within fifteen days after receipt of

such notice, any such Investor shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such Investor requests to be registered.

of the Shares or its right to purchase the Shares that would constitute a sale within the meaning of the Securities Act other than transactions exempt from the registration requirements of the Securities Act, as contemplated in the Registration Statement and as described below, and that it will promptly notify the Company of any material changes in the information set forth in the Registration Statement regarding the Investor (other than the number of Securities beneficially owned by it) or its plan of distribution attached as Exhibit “B” hereto.

     (b) Except in the event that paragraph (c) below applies, the Company shall: (i) if deemed necessary by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not 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 not misleading, and so that, as thereafter delivered to purchasers of the Shares being sold thereunder, such Prospectus will not 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 light of the circumstances under which they were made, not misleading; (ii) provide the Investor with either copies of any documents filed pursuant to Section 3(b)(i) or access to such documents electronically; and (iii) upon request, inform each Investor who so requests that the Company has complied with its obligations in Section 3(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared effective, the Company will notify the Investor to that effect, will use its best efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly notify the Investor pursuant to Section 3(b)(i) hereof when the amendment has become effective).

     (c) Subject to paragraph (d) below, in the event: (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to the Registration Statement or related Prospectus or for additional information; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Shares for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) following the 60^th Business Day of the Effective Date, if the Board of Directors determines in good faith, by appropriate resolutions, that, as a result of an event or circumstance which necessitates the making of any material changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any 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 not misleading, and that in the case of the Prospectus, it will not contain any 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; then the Company shall promptly deliver a certificate in writing or electronically to the Investor (the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investor will refrain from selling any Shares pursuant to the Registration Statement (a “Suspension”) until the Investors are advised in writing by the Company that the current Prospectus may be used, and has received copies of any additional or supplemental filings that are

incorporated or deemed incorporated by reference in any such Prospectus. Notwithstanding the foregoing, the right of the Company to implement a Suspension shall be limited to two such Suspensions and an aggregate of 45 days in any twelve-month period. In the event of any Suspension, the Company will use its reasonable best efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable after delivery of a Suspension Notice to the Investors. In the event, within any twelve month period, of (i) three or more such Suspensions or (ii) one or two Suspensions exceeding an aggregate of 45 days, (an “Excess Suspension”) the Company shall make payment to the Investor as liquidated damages therefore an amount equal to one percent (1%) of the Purchase Price paid for the Shares then held by the Investor per each 30 day period of the Excess Suspension, provided that in no event shall the total of all such amounts plus any Late Registration Payments under Section 1(b) exceed in the aggregate twelve percent (12%) of the Purchase Price. Any liquidated damages payable as the result of an Excess Suspension shall be paid on each 30^th anniversary date of each Excess Suspension, and liquidated damages payable on account of Excess Suspension periods of less than 30 days shall be pro rated on a daily basis. In addition, the Investor shall be entitled to specific performance in the event that the Company fails to comply with the provisions of this Section 3(c). The Investor covenants that from the date hereof it will maintain in confidence the receipt and content of any Suspension Notice provided in accordance with this paragraph (c) in accordance with and subject to Section 4.6 of Annex I to the Securities Purchase Agreement.

     (d) If a Suspension is not then in effect, the Investor may sell Shares under the Registration Statement, provided that it complies with any applicable prospectus delivery requirements. Upon receipt of a request therefor, the Company will provide an adequate number of current Prospectuses to the Investor and to any other parties requiring such Prospectuses.

     (e) In the event of a sale of Shares by the Investor, unless such requirement is waived by the Company in writing, the Investor must also deliver to the Company’s transfer agent, with a copy to the Company, such documentation reasonably requested by the transfer agent including, without limitation, a Certificate of Subsequent Sale substantially in the form attached hereto as Exhibit A, so that the Shares may be properly transferred.

     (f) Following the Effective Date or at such earlier time as a legend is no longer required for certain Shares, the Company will no later than three (3) Business Days following the delivery by an Investor to the Company or the Transfer Agent (with notice to the Company) of (i) a legended certificate representing such Shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to effect the reissuance and/or transfer and an opinion of Investor’s counsel reasonably acceptable to the Company), and (ii) if applicable, the Certificate of Subsequent Sale in the form attached hereto as Exhibit “A”, issue irrevocable transfer agent instructions and to deliver or cause to be delivered to such Investor a certificate representing such Shares that is free from all restrictive and other legends.

CERTIFICATE OF SUBSEQUENT SALE

     The undersigned hereby certifies, in connection with the sale of shares of Common Stock of the Company included in the table of Selling Shareholders in the Prospectus, that the undersigned has sold the Shares pursuant to the Prospectus and in a manner described under the caption “Plan of Distribution” in the Prospectus and that such sale complies with all applicable securities laws.

     In the event that you receive a stock certificate(s) representing more shares of Common Stock than have been sold by the undersigned, then you should return to the undersigned a newly issued certificate for such excess shares in the name of the Record Holder and BEARING A RESTRICTIVE LEGEND. Further, you should place a stop transfer on your records with regard to such certificate.

A-1

     The selling security holders may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling security holders may use any one or more of the following methods when selling shares:

     In connection with the sale of our common stock or interests therein, the selling security holders 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 security holders 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 security holders 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 selling security holders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

B-3

     The selling security holders may also engage in short sales against the box, puts and calls and other transactions in our securities or derivatives of our securities and may sell or deliver shares in connection with these trades.

     Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling security holders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling stockholder. The selling security holders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

     The selling security holders 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 after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling security holders to include the pledgee, transferee or other successors in interest as selling security holders under this prospectus.

     The selling security holders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the shares of common stock from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling security holders to include the pledgee, transferee or other successors in interest as selling security holders under this prospectus.

     The selling security holders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

     We are required to pay all fees and expenses incident to the registration of the shares of common stock. We have agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

     The selling security holders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares of common stock, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling stockholder. If we are notified by any selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file a supplement to this prospectus. If the selling security holders use this prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.

B-3

     The anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934 may apply to sales of our common stock and activities of the selling security holders.
