any of the Registrable Securities included in the Registration Statement. An Investor shall provide such information to the Company at least four (4) Business Days prior to the first anticipated filing date of such Registration Statement if such Investor elects to have any of the Registrable Securities included in the Registration Statement.

(b) Each Investor, by its acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of the Registration Statement hereunder, unless such Investor has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement.

(c) Each Investor agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(g) hereof, such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until the Investor is advised by the Company that such dispositions may again be made.

6. Indemnification.

(a) Indemnification by the Company. The Company will indemnify and hold harmless each Investor and its officers, directors, members, employees and agents, successors and assigns, and each other person, if any, who controls such Investor within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof; (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called a “Blue Sky Application “); (iii) 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 (iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by an Investor or any controlling person of an Investor in writing specifically for use in such Registration Statement or Prospectus.

(b) Indemnification by the Investors. Each Investor agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary Prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by such Investor or any controlling person of such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 6 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation. In addition, an Investor shall not be liable hereunder to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of the Company’s, or any underwriter’s, or their representatives’ failure to send or give a copy of a final Prospectus, as the same may be then supplemented or amended, to the person or entity asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of securities to such person or entity if such statement or omission was corrected in such final Prospectus.

5

(c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation.

(d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

Exhibit A

Plan of Distribution

The selling stockholders, which 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:

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, pledgees 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

10

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. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of the warrants.

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, provided that they meet the criteria and conform to the requirements of that rule.

The selling stockholders and 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. Selling stockholders will be subject to the prospectus delivery requirements of the Securities Act, unless an exemption therefrom is available.

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 agents, 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.

There can be no assurance that any selling shareholder will sell any or all of the shares of common stock registered pursuant to the shelf registration statement, of which this prospectus forms a part.

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. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We will pay all expenses of the registration of the shares of common stock pursuant to the registration rights agreement, estimated to be $35,000 in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities or “blue sky” laws and the selling stockholders’ expenses; provided, however, that a selling shareholder will pay all underwriting discounts and selling commissions, if any.

We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144 of the Securities Act without regard to any volume limitation requirements under Rule 144 of the Securities Act.

APPENDIX A

DEFINITIONS OF CERTAIN TERMS

IN SELLING SHAREHOLDERS QUESTIONNAIRE

(Arranged Alphabetically)

1. “Affiliate.” An “affiliate” of any entity is a person that, directly or indirectly, through one or more intermediaries, controls, is controlled by or is under common control with such person (for example, a parent subsidiary or sister corporation).

2. “Associate.” “Associate” for the purpose of Question 4 means (1) any corporation or organization (other than the Company or a majority-owned subsidiary of the Company) of which you are an officer or partner or are, directly or indirectly, the beneficial owner of 10% or more of any class of equity securities; (2) any trust or other estate in which you have a substantial beneficial interest or as to which you serve as a trustee or in a similar fiduciary capacity; and (3) any member of your immediate family. “Associate” for the purpose of Question 13 means the same as the foregoing, except that subsection (1) shall state “any corporation or organization … of which you are an executive officer.”

3. “Beneficially Owned” or “Beneficial Ownership.”

a. General Rule. Under the rules of the SEC, you are deemed to “beneficially own” or be the “beneficial owner” of any security with respect to which you have or share, directly or indirectly, through any contract, arrangement, understanding, relationship, agreement or otherwise: (1) Voting Power (which includes the power to vote, or to direct the voting of, such security); and/or (2) Investment Power (which includes the power to dispose, or to direct the disposition of, such security). You are also the beneficial owner of a security if you, directly or indirectly, create or use a trust, proxy, power of attorney, pooling arrangement or any other contract, arrangement, or device with the purpose or effect of divesting yourself of beneficial ownership of a security or preventing the vesting of such beneficial ownership.

Some specific applications of the above definition of beneficial ownership are:

(i) Family situations. Although the determination of beneficial ownership of securities is necessarily a question to be determined in light of the facts of each particular case, family relationships may result in your having, or sharing, the power to vote, or direct the voting of, or dispose, or direct the disposition of, shares held by your family members. In view of the broad definition of “Beneficial Ownership,” it may be prudent to include such shares in your beneficial ownership disclosure and then disclaim beneficial ownership of such securities pursuant to Question 6.

(ii) Shares held by others for your benefit. There are numerous instances in which you may have, or share, voting or investment power (as defined above) over securities, although the securities are held by another person or entity. For example, you may have or share such power in securities held for you or your family members living with you by custodians, brokers, relatives, executors, administrators or trustees; securities held for your account by pledgees; securities owned by a partnership in which you are a member; and securities owned by a corporation which is or should be regarded as a personal holding company of yours or is controlled by you.

(iii) Shares held by you for the benefit of others. Beneficial ownership of securities also includes securities held in your name as a trustee, custodian or other fiduciary where you have, or share, voting or investment power with respect to such securities.

b. Options and other rights to acquire securities. In addition to being beneficial owner of securities over which you have, or share, voting or investment power, the SEC has determined that you are deemed to be the beneficial owner of a security if you have a right to acquire beneficial ownership of (i.e., the right to obtain or share voting or investment power over) such security at any time within sixty days. Examples of such rights would include the right to acquire: (i) through the exercise of any option, warrant or similar right; (ii) through conversion of any

13

security; or (iii) pursuant to the power to revoke, or the provision for automatic termination of, a trust, discretionary account or similar arrangement. Also, if you have acquired or hold any options, convertible securities or power to revoke such a trust with the “purpose or effect” of changing or influencing control of the Company, you are deemed the beneficial owner of the underlying securities upon such acquisition, without regard to the sixty-day rule stated above.

4. “Control” or “Controlled.” The term “control” means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of the Company, whether through the ownership of voting securities, by contract or otherwise. An executive officer or director of a company generally is considered to control that company. It is suggested that, if you are in doubt as to the meaning of “control” in a particular context, you communicate with counsel.

5. “Equity Security.” The definition of “equity security” encompasses more than common and preferred stock. It includes for instance convertible debt instruments as well as warrants and options to acquire stock or similar securities. If you have a question as to the proper characterization of your holdings you should consult with the Company’s legal counsel.

6. “Executive Officer.” “Executive officer” for the purpose of this Questionnaire means the president of a company, any vice president of it in charge of a principal business unit, division or function (such as sales, administration or finance), any other officer who performs a policy-making function or any other person who performs similar policy-making functions for the company. Executive officers of subsidiaries may be deemed executive officers of a company if they perform such policy-making functions for the company.

7. “Immediate Family.” “Immediate family” for the purpose of this Questionnaire includes your spouse, parents, children, siblings, mothers-and fathers-in-law, sons- and daughters-in-law, and brothers- and sisters-in-law.

8. “Officer.” “Officer” means a president, vice president, secretary, treasurer or principal financial officer, comptroller or principal accounting officer, and any person routinely performing corresponding functions with respect to any organization whether incorporated or unincorporated.

9. “Person.” “Person” for the purpose of this Questionnaire means an individual, a corporation, a partnership, an association, a joint-stock company, a business trust, an unincorporated organization, or any other entity.

10. “Transaction” or “Transactions.” “Transaction” or “transactions” is to be understood in its broadest sense, and includes the direct or indirect receipt of anything of value. No transaction or interest therein need be disclosed where: (a) the rates or charges involved in the transaction are determined by competitive bids, or the transaction involves the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental authority; (b) the transaction involves services as a bank depository of funds, transfer agent, registrar, trustee under a trust indenture or similar services; or (c) the interest in question arises solely from the ownership of securities of the Company and the interested party receives no extra or special benefit not shared on a pro-rata basis by all shareholders.
