EXPLANATORY NOTE

This Post-Effective Amendment No. 3 to Form S-3 Registration Statement is being filed to convert the Registrant’s registration statement on Form S-3 (Registration No. 333-165661), or the Original Registration Statement, declared effective by the Securities and Exchange Commission, or the Commission, on May 19, 2010, which registered shares of common stock for resale, from time to time, on behalf of certain selling shareholders, back into a registration statement on Form S-3. Upon filing its Annual Report on Form 10-K for the fiscal year ended June 30, 2013 with the Commission, the Registrant was no longer eligible to use Form S-3 in connection with the current offering. On September 6, 2013 and September 18, 2013, the Registrant filed post-effective amendments to the Original Registration Statement converting the Original Registration Statement into a registration statement on Form S-1, which was declared effective by the Commission on September 19, 2013. In December 2013, the Registrant became eligible to use Form S-3 in connection with the current offering. All filing fees payable in connection with the registration of these securities were previously paid in connection with the filing of the Original Registration Statement.

The information in this preliminary prospectus is not complete and may be changed. The selling shareholders may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities, and the selling shareholders are not soliciting offers to buy these securities, in any state where the offer or sale of these securities is not permitted.

SUBJECT TO COMPLETION, DATED FEBRUARY 12, 2014

PROSPECTUS

14,611,809 Shares of Common Stock

This prospectus relates solely to the resale or other disposition by the selling shareholders identified in this prospectus, or their transferees, of up to an aggregate of (i) 4,521,619 shares of common stock issued upon conversion of 794,659 shares of Series A Convertible Preferred Stock, (ii) 10,028,888 shares of common stock issuable upon exercise of warrants, or the Warrants, and (iii) 61,302 shares of common stock issued upon exercise of a Warrant in July 2011. The shares of Series A Convertible Preferred Stock and Warrants were issued and sold to the selling shareholders pursuant to a Purchase Agreement, dated as of February 18, 2010, between us and the selling shareholders, or the Purchase Agreement.

We initially sold to the selling shareholders Warrants to purchase 6,373,266 shares of common stock at an exercise price of $2.583 per share. However, subsequent issuances of our securities triggered the weighted-average anti-dilution provisions of such warrants and as of January 22, 2014, there are outstanding Warrants to purchase up to an aggregate of 10,028,888 shares of common stock at an exercise price of $1.628 per share. If we issue shares of common stock at a price that is lower than the warrant exercise price in effect immediately prior to such issuance, then the Warrant exercise price would be adjusted downward. The magnitude of such adjustment is dependent on the number of shares we issue and the price at which such shares are issued.

The selling shareholders may, from time to time, sell, transfer, or otherwise dispose of any or all of their shares of common stock covered hereby 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. See “Plan of Distribution” for additional information.

We are not offering any shares of common stock for sale under this prospectus, and we will not receive any of the proceeds from the sale or other disposition of the shares of common stock covered hereby. However, we will receive the exercise price of any warrants exercised for cash.

Our common stock is traded on The NASDAQ Capital Market under the symbol “OVRL”. On February 11, 2014, the last reported sale price for our common stock on The NASDAQ Capital Market was $0.97 per share.

We will pay the expenses related to the registration of the shares of common stock covered by this prospectus. The selling shareholders will pay any commissions and selling expenses they may incur.

We have also filed registration statements with the Securities and Exchange Commission related to the resale or other disposition by certain selling shareholders of (i) up to an aggregate of 12,564,212 shares of our common stock, which are outstanding or are issuable upon exercise of outstanding warrants (Registration No. 333-173542); and (ii) up to an aggregate of 11,593,976 shares of our common stock, which were issued or are issuable upon conversion of convertible notes or were issued or are issuable as interest payments on such convertible notes in shares (Registration No. 333-187241).

Our business and an investment in our securities involve significant risks. You should read the section entitled “Risk Factors” on page 8 of this prospectus and the risk factors incorporated by reference into this prospectus as described in that section before investing in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is                     , 2014

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any prospectus supplement and the documents we incorporate by reference in this prospectus or any prospectus supplement contain certain forward-looking statements that involve risks, uncertainties and assumptions that are difficult to predict. Words and expressions reflecting optimism, satisfaction or disappointment with current prospects, as well as words such as “believes,” “hopes,” “intends,” “estimates,” “expects,” “projects,” “plans,” “anticipates” and variations thereof, or the use of future tense, identify forward-looking statements, but their absence does not mean that a statement is not forward-looking. Such forward-looking statements are not guarantees of performance and our actual results could differ materially from those contained in such statements. In evaluating such statements we urge you to specifically consider various factors identified in this prospectus, including the matters set forth under the heading “Risk Factors” on page 8 and the risk factors incorporated by reference into this prospectus as described in that section, and in the documents we may incorporate into this prospectus or any prospectus supplement by reference, any of which could cause actual results to differ materially from those indicated by such forward-looking statements. Forward-looking statements speak only as of the date of this prospectus or any prospectus supplement and we undertake no obligation to publicly update any forward-looking statements to reflect new information, events or circumstances after the date of this prospectus or any prospectus supplement.

These forward-looking statements reflect our current views with respect to future events and are based on our currently available financial, economic and competitive data and on current business plans. Such forward-looking statements are not guarantees of performance and our actual results could differ materially from those contained in such statements. We may not actually achieve the plans, intentions or expectations disclosed in these forward-looking statements and you should not place undue reliance on our forward-looking statements. Actual events or results may differ materially depending on risks and uncertainties that may affect our operations, markets, services, prices and other factors. Factors that could cause or contribute to such differences include, but are not limited to: our ability to maintain and increase sales volumes of our products; our ability to continue to aggressively control costs and operating expenses; our ability to achieve the intended cost savings and maintain quality with our manufacturing partner; our ability to generate cash from operations; the ability of our suppliers to provide an adequate supply of components for our products at prices consistent with historical prices; our ability to raise outside capital and to repay our debt as it comes due; our ability to introduce new competitive products and the degree of market acceptance of such new products; the timing and market acceptance of new products introduced by our competitors; our ability to maintain strong relationships with branded channel partners; our ability to maintain the listing of our common stock on The NASDAQ Capital Market; customers’, suppliers’ and creditors’ perceptions of our continued viability; rescheduling or cancellation of customer orders; loss of a major customer; our ability to enforce our intellectual property rights and protect our intellectual property; general competition and price measures in the market place; unexpected shortages of critical components; worldwide information technology spending levels; and general economic conditions.

We intend that all forward-looking statements made will be subject to safe harbor protection of the federal securities laws pursuant to Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Exchange Act. Except as required by law, we do not undertake any responsibility to update these forward-looking statements to take into account events or circumstances that occur after the date of this prospectus or any prospectus supplement.

February 2010 Financing

On February 18, 2010, we entered into a placement agency agreement, or the Placement Agency Agreement, with Roth Capital Partners, LLC, or the Placement Agent, relating to a proposed offering of our securities.

On February 18, 2010, we entered into the Purchase Agreement pursuant to which we issued and sold in a private placement an aggregate of 794,659 shares of Series A Convertible Preferred Stock, no par value per share, or the Series A Preferred Stock, initially convertible into 4,521,619 shares of common stock, and (ii) warrants initially exercisable to purchase up to 6,373,266 shares of common stock, or the Warrants, for an aggregate offering price of approximately $11.9 million, or the PIPE.

In addition, in connection with the PIPE and as partial compensation for the Placement Agent’s services, we issued to the Placement Agent warrants initially exercisable to purchase up to 180,865 shares of common stock at an exercise price of $2.952 per share, or the Placement Agent Warrants.

In connection with the PIPE, we agreed to solicit shareholder approval of the full conversion of outstanding shares of Series A Preferred Stock and the full exercise of the Warrants, or the Proposal, at a shareholders’ meeting to be held not later than April 30, 2010, or the Shareholders’ Meeting. We filed a definitive proxy statement dated March 31, 2010 with the SEC describing in detail the Proposal and the other matters included on the agenda for the Shareholders’ Meeting to be held on April 23, 2010. At the Shareholders’ Meeting, our shareholders approved all matters included on the agenda for the meeting, including the Proposal. Pursuant to the terms of the Certificate of Determination of Rights, Preferences, Privileges and Restrictions of Series A Convertible Preferred Stock, or the Certificate of Determination, all outstanding shares of Series A Preferred Stock automatically, and without any further action on the part of the holders thereof, converted into shares of common stock upon receipt of shareholder approval of the Proposal.

On April 29, 2010, we filed the Certificate of Amendment of Certificate of Determination (the “Certificate of Amendment”) with the Secretary of State of the State of California, which is effective as of April 29, 2010, to reduce the authorized number of shares of Series A Preferred Stock to zero.

Warrants

Each Warrant had an initial exercise price of $2.583 per share of common stock ($2.952 per share of common stock in the case of the Placement Agent Warrants). The Warrants and the Placement Agent Warrants are immediately exercisable, have a five year term and provide for weighted-average anti-dilution protection.

Subsequent issuances of our securities triggered the weighted-average anti-dilution provisions of such warrants and as of January 22, 2014, there are outstanding Warrants to purchase up to an aggregate of 10,028,888 shares of common stock at an exercise price of $1.628 per share. If we issue shares of common stock at a price that is lower than the warrant exercise price in effect immediately prior to such issuance, then the Warrant exercise price would be adjusted downward. The magnitude of such adjustment is dependent on the number of shares we issue and the price at which such shares are issued.

5

Registration Rights Agreement

We also entered into a Registration Rights Agreement, dated as of February 22, 2010, by and among the Company, the Investors and the Placement Agent, or the Registration Rights Agreement. Pursuant to the Registration Rights Agreement, we agreed to file a registration statement with the SEC within 30 days of closing the PIPE to register the shares of common stock issued upon conversion of the Series A Preferred Stock and issuable upon exercise of the Warrants and the Placement Agent Warrants. The registration statement of which this prospectus is a part has been filed to satisfy this obligation. The Placement Agent has elected to not include the shares of common stock issuable upon exercise of the Placement Agent Warrants in the registration statement of which this prospectus is a part. In addition, if we do not meet certain other obligations set forth in the Registration Rights Agreement, we will be required to pay liquidated damages in an amount equal to 1.5% of the aggregate amount invested by each selling shareholder for each 30-day period or pro rata portion thereof during which we are not in compliance with the terms of the Registration Rights Agreement.

The shares of Series A Preferred Stock, the Warrants and the Placement Agent Warrants, and the shares of common stock issued upon conversion of the Series A Preferred Stock and issuable upon exercise of the Warrants and the Placement Agent Warrants, were offered and sold by us pursuant to an exemption from the registration requirements of the Securities Act provided by Section 4(2) thereunder.

The above descriptions of the Placement Agency Agreement, the Purchase Agreement, the Certificate of Determination, the Warrants and the Registration Rights Agreement are qualified in their entirety by reference to Exhibits 1.1, 10.1, 3.1, 4.2 and 4.3, respectively, to our Current Report on Form 8-K filed with the SEC on February 24, 2010, and the above description is qualified in its entirety by reference to these documents. The above description of the Certificate of Amendment is qualified in its entirety by reference to Exhibit 3.1 to our Current Report on Form 8-K filed with the SEC on May 5, 2010, and the above description is qualified in its entirety by reference to this document.

RISK FACTORS

An investment in our securities involves a high degree of risk. In addition to the other information included in this prospectus, you should carefully consider each of the following risk factors, as well as those set forth in our most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q on file with the SEC, which are incorporated by reference into this prospectus. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus and any accompanying prospectus supplement. The risks and uncertainties not presently known to us or that we currently deem immaterial may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Risks Related to Our Company

We have pledged substantially all of our assets to our lenders.

We have existing obligations outstanding in the amount of $3.5 million in debt to Silicon Valley Bank and approximately $9.5 million in debt pursuant to outstanding convertible notes. We have pledged 65% of the stock of certain of our foreign subsidiaries as security on such convertible notes and the initial purchasers of such convertible notes may foreclose on 65% of the stock in such foreign subsidiaries if we fail to pay the convertible notes when they become due. If we fail to repay Silicon Valley Bank when our obligations are due, Silicon Valley Bank may foreclose on substantially all of our assets other than the 65% of the stock of such foreign subsidiaries, which could result in a complete loss of investment for our shareholders.

Risks Related to this Offering

Our stock price has been volatile and your investment in our common stock could decrease in value.

There has been significant volatility in the market price and trading volume of equity securities, in general, and in our stock price, specifically. Our specific performance as well as broad market fluctuations may negatively affect the market price of our common stock. You may not be able to resell your shares of common stock at or above the price you pay for those shares. Factors that could affect our market price include, among others:

• actual or anticipated fluctuations in our operating results or future prospects;

• our announcements or our competitors’ announcements of new products;

• public reaction to our press releases, our other public announcements and our filings with the SEC;

• actual or anticipated fluctuations in our operating results or future prospects;

• strategic actions by us or our competitors;

• changes in financial markets or general economic conditions;

• our ability to raise additional capital as needed;

• developments regarding our patents or proprietary rights or those of our competitors; and

• changes in stock market analyst recommendations or earnings estimates regarding our common stock, other comparable companies or our industry generally.

Future sales of our securities could adversely affect the market price of our common stock and our future capital-raising activities could involve the issuance of equity securities, which would dilute your investment and could result in a decline in the trading price of our common stock.

We may sell securities in the public or private equity markets if and when conditions are favorable, even if we do not have an immediate need for additional capital at that time. Sales of substantial amounts of shares of our common stock, or the perception that such sales could occur, could adversely affect the prevailing market

8

price of shares of common stock and our ability to raise capital. We may issue additional shares of common stock in future financing transactions or as incentive compensation for our executive management and other key personnel, consultants and advisors. Issuing any equity securities would be dilutive to the equity interests represented by our then-outstanding shares of common stock. The market price for our common stock could decrease as the market takes into account the dilutive effect of any of these issuances.

Sales of shares issued in the PIPE may cause the market price of our shares to decline.

On February 22, 2010, we closed the PIPE and issued 794,659 shares of Series A Preferred Stock, initially convertible into 4,521,619 shares of common stock, Warrants initially exercisable to purchase up to 6,373,266 shares of common stock, and Placement Agent Warrants initially exercisable to purchase up to 180,865 shares of common stock. Pursuant to the terms of the Certificate of Determination, all outstanding shares of Series A Preferred Stock automatically, and without any further action on the part of the holders thereof, converted into shares of common stock upon receipt of shareholder approval of the Proposal as described above. We have agreed to register with the SEC the shares of common stock issued upon conversion of the Series A Preferred Stock and issuable upon exercise of the Warrants and the Placement Agent Warrants for resale. The Placement Agent has elected to not include the shares of common stock issuable upon exercise of the Placement Agent Warrants in the registration statement of which this prospectus is a part. Upon the effectiveness of the registration statement of which this prospectus is a part, the 14,611,809 shares of common stock issued upon conversion of the Series A Preferred Stock, issued upon exercise of a Warrant in July 2011 and issuable upon exercise of the Warrants may be freely sold in the open market. The sale of a significant amount of these shares in the open market or the perception that these sales may occur could cause the market price of our common stock to decline or become highly volatile.

The exercise price of the Warrants may be further reduced upon the issuance of shares of common stock, which would result in our company receiving less proceeds per share from the exercise of the Warrants.

After the Warrants were issued, the initial exercise price of the Warrants was reduced because the issuance of additional securities triggered the weighted-average anti-dilution provisions of the Warrants. For example, in February 2013, we issued and sold convertible notes in an aggregate original principal amount of $13.25 million, or the Initial Notes. Upon issuing the Initial Notes, the exercise price of the Warrants was adjusted downward resulting in Warrants to purchase up to an aggregate of 9,258,730 shares of common stock at an exercise price of $1.763 per share. In June 2013, we issued an aggregate of 348,490 shares of common stock to the holders of the outstanding Initial Notes as payment of interest on the Initial Notes, which caused the exercise price of the Warrants to be adjusted downward resulting in Warrants to purchase up to an aggregate of 9,295,459 shares of common stock at an exercise price of $1.756 per share. In November 2013, we issued an aggregate of 379,310 shares of common stock to the holders of the outstanding Initial Notes as payment of interest on the Initial Notes and issued and sold additional convertible notes, or the Additional Notes, in an aggregate original principal amount of $3.0 million, which collectively caused the exercise price of the Warrants to be adjusted downward resulting in Warrants to purchase up to an aggregate of 9,629,274 shares of common stock at an exercise price of $1.695 per share. In addition, in December 2013 and January 2014, we issued and sold Additional Notes in an aggregate original principal amount of $4.0 million. Upon issuing such Additional Notes, the exercise price of the Warrants was adjusted downward resulting in Warrants to purchase up to an aggregate of 10,028,888 shares of common stock at an exercise price of $1.628 per share. If we issue shares of common stock at a price that is lower than the exercise price of the Warrants in effect immediately prior to such issuance, including any additional issuance of shares of common stock as payment of any or all of the interest on the outstanding Initial Notes or Additional Notes, as applicable, then the exercise price of the Warrants would be adjusted downward. The magnitude of such adjustment is dependent on the number of shares we issue and the price at which such shares are issued, which price, in the case of the Initial Notes, will not be less than $0.98 per share and, in the case of the Additional Notes, will not be less than $0.90 per share. Any such adjustment would cause us to receive less proceeds per share from the exercise of the Warrants.

We may have to pay liquidated damages to our investors, which will increase our negative cash flows.

In connection with the PIPE described above, we entered into the Registration Rights Agreement. Under the terms of the Registration Rights Agreement, if the registration statement of which this prospectus forms a part has not been declared effective within the time periods specified in the Registration Rights Agreement (with certain limited exceptions), or we otherwise fail to comply with certain provisions set forth in the Registration Rights Agreement, then we will be required to pay the investors, as liquidated damages, 1.5% of the amount invested for each 30-day period (or pro rata portion thereof) during which such failure continues until the shares are sold or can be sold without restriction under Rule 144. There can be no assurance that the registration statement of which this prospectus forms a part will be declared effective by the SEC or will remain effective for the time periods necessary to avoid payment of liquidated damages.

We have never paid cash dividends on our common stock and do not expect to pay cash dividends on our common stock for the foreseeable future.

We have never paid cash dividends on our common stock and do not anticipate that any cash dividends will be paid on shares of our common stock for the foreseeable future. The payment of any cash dividend by us will be at the discretion of our board of directors and will depend on, among other things, our earnings, capital, regulatory requirements and financial condition.

10

USE OF PROCEEDS

We will not receive any of the proceeds from the sale or other disposition of the shares of common stock offered hereby. However, we will receive the exercise price of any warrants exercised for cash. To the extent that we receive cash upon exercise of any warrants, we expect to use that cash for general corporate purposes.

SELLING SHAREHOLDERS

We have prepared this prospectus to allow the selling shareholders or their donees, pledgees, transferees or other successors in interest to sell or otherwise dispose of, from time to time, up to 14,611,809 shares of our common stock issued upon conversion of the Series A Preferred Stock or issued or issuable upon exercise of the Warrants acquired pursuant to the Purchase Agreement. The table below presents information regarding the selling shareholders, the shares of common stock beneficially owned by them prior to this offering and the shares of common stock that they may sell or otherwise dispose of from time to time under this prospectus.

We do not know when or in what amounts the selling shareholders may sell or otherwise dispose of the shares of common stock covered hereby. The selling shareholders might not sell any or all of the shares covered by this prospectus or may sell or dispose of some or all of the shares other than pursuant to this prospectus. Because the selling shareholders may not sell or otherwise dispose of some or all of the shares covered by this prospectus and because there are currently no agreements, arrangements or understandings with respect to the sale or other disposition of any of the shares, we cannot estimate the number of the shares that will be held by the selling shareholders after completion of this offering. However, for purposes of this table, we have assumed that all of the shares of common stock covered by this prospectus will be sold by the selling shareholders.

PLAN OF DISTRIBUTION

The selling shareholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling shareholder 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 shareholders may use any one or more of the following methods when disposing of shares or interests therein:

• ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

• block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

• purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

• an exchange distribution in accordance with the rules of the applicable exchange;

• privately negotiated transactions;

• short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

• through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

• broker-dealers may agree with the selling shareholders to sell a specified number of such shares at a stipulated price per share;

• a combination of any such methods of sale; and

• any other method permitted by applicable law.

The selling shareholders 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 shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The selling shareholders 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 shareholders 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 shareholders may also sell shares of 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 shareholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling shareholders 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

15

shareholders 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 Warrants for cash, however, we will receive the exercise price of such Warrants.

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

The selling shareholders 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 shareholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of common stock to be sold, the names of the selling shareholders, 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.

We have advised the selling shareholders 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 shareholders 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 shareholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling shareholders 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 shareholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling shareholders 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 without restriction pursuant to Rule 144 of the Securities Act.

Item 15. Indemnification of Directors and Officers

California Incorporation

Section 317 of the California General Corporation Law, or the CGCL, provides a detailed statutory framework covering limitation of liability of directors in certain instances and indemnification of any officer or other agent of a corporation who is made or threatened to be made a party to any legal proceeding by reason of his or her services on behalf of such corporation.

With respect to limitation of liability, the CGCL permits a California corporation to adopt a provision in its articles of incorporation reducing or eliminating the liability of a director to the corporation or its shareholders for monetary damages for breach of the fiduciary duty of care, provided that such liability does not arise from certain proscribed conduct (including intentional misconduct and breach of duty of loyalty). The CGCL in this regard relates only to actions brought by shareholders on behalf of the corporation (i.e., “derivative actions”) and does not apply to claims brought by outside parties.

With respect to indemnification, the CGCL provides that to the extent any officer, director or other agent of a corporation is successful “on the merits” in defense of any legal proceeding to which such person is a party or is threatened to be made a party by reason of his or her service on behalf of such corporation or in defense of any claim, issue, or matter therein, such agent shall be indemnified against expenses actually and reasonably incurred by the agent in connection therewith, but does not require indemnification in any other circumstance. The CGCL also provides that a corporation may indemnify any agent of the corporation, including officers and directors, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in a third party proceeding against such person by reason of his or her services on behalf of the corporation, provided the person acted in good faith and in a manner he or she reasonably believed to be in the best interests of such corporation. The CGCL further provides that in derivative suits a corporation may indemnify such a person against expenses incurred in such a proceeding, provided such person acted in good faith and in a manner he or she reasonably believed to be in the best interests of the corporation and its shareholders. Indemnification is not available in derivative actions (i) for amounts paid or expenses incurred in connection with a matter that is settled or otherwise disposed of without court approval or (ii) with respect to matters for which the agent shall have been adjudged to be liable to the corporation unless the court shall determine that such person is entitled to indemnification.

The CGCL permits the advancing of expenses incurred in defending any proceeding against a corporate agent by reason of his or her service on behalf of the corporation upon the giving of a promise to repay any such sums in the event it is later determined that such person is not entitled to be indemnified. Finally, the CGCL

II-1

provides that the indemnification provided by the statute is not exclusive of other rights to which those seeking indemnification may be entitled, by bylaw, agreement or otherwise, to the extent additional rights are authorized in a corporation’s articles of incorporation. The law further permits a corporation to procure insurance on behalf of its directors, officers and agents against any liability incurred by any such individual, even if a corporation would not otherwise have the power under applicable law to indemnify the director, officer or agent for such expenses.

The registrant’s articles of incorporation and bylaws implement the applicable statutory framework by limiting the personal liability of directors for monetary damages for a breach of a director’s fiduciary duty of care and making indemnification mandatory in those situations where it is merely permissible under the CGCL.

General

The registrant maintains insurance for officers and directors against certain liabilities, including liabilities under the Securities Act. The effect of this insurance is to indemnify any officer or director of the registrant against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement, incurred by an officer or director upon a determination that such person acted in good faith. The registrant pays the premiums for such insurance.

Pursuant to separate indemnification agreements with the registrant, each executive officer and director of the registrant is indemnified against all liabilities relating to his or her position as an executive officer or director of the registrant, to the fullest extent permitted under applicable law.

The registrant may also enter into indemnification agreements with underwriters or agents providing that the underwriters or agents, as applicable, have to indemnify and hold harmless the registrant, its directors, each officer who signed the registration statement and any person who controls the registrant within the meaning of the Securities Act, from and against certain civil liabilities, including liabilities under the Securities Act.

provided, however, that paragraphs (i), (ii), and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

2. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

4. That, for purposes of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Re:    Registration of Securities of Overland Storage, Inc.

Ladies and Gentlemen:

At your request, we have examined the Post-Effective Amendment No. 3 to Registration Statement on Form S-3 (the “Registration Statement”) to be filed by you (the “Company”) with the Securities and Exchange Commission (“SEC”), on or about February 12, 2014, in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of an aggregate of (i) 4,521,619 shares (the “Conversion Shares”) of your common stock, no par value per share (the “Common Stock”), issued upon conversion of 794,659 shares of your Series A Convertible Preferred Stock, (ii) 10,028,888 shares of Common Stock (the “Warrant Shares”) issuable upon exercise of outstanding warrants (the “Warrants”) and (iii) 61,302 shares of Common Stock issued upon exercise of a Warrant in July 2011 (the “July 2011 Shares” and, together with the Warrant Shares and the Conversion Shares, the “Shares”). The Shares are accompanied by a Common Stock purchase right (the “Purchase Right”) pursuant to the Shareholder Rights Agreement, dated August 22, 2005, as amended by Amendment No. 1 to Shareholder Rights Agreement dated March 21, 2011, between the Company and Wells Fargo Bank, N.A., as Rights Agent (the “Rights Agreement”). We understand that the Shares are to be sold by the selling shareholders to the public from time to time as described in the Registration Statement.

We have examined originals or copies of those corporate and other records and documents we considered appropriate. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such latter documents. As to any facts material to the opinions expressed herein which were not independently established or verified, we have relied upon oral or written statements and representations of officers and other representatives of the Company.

In connection with the opinions expressed below, we have assumed that, at or prior to the time of delivery of any Shares, (i) the Board of Directors of the Company (the “Board of Directors”) has taken all necessary corporate action to authorize the issuance and sale of such Shares and such authorization has not been modified or rescinded, (ii) the Registration Statement’s effectiveness has not been terminated or rescinded, (iii) an appropriate prospectus supplement with respect to such Shares has been prepared, delivered and filed in compliance with the Securities Act and the applicable rules and regulations thereunder, (iv) there has not occurred any change in law affecting the validity or enforceability of such Shares and (v) a sufficient number of shares of Common Stock is authorized and available for issuance. We have also assumed that the terms of the issuance and sale of any Shares have been duly established in conformity with the Amended and Restated Articles of Incorporation of the Company, as amended, as presently in effect (the “Articles of Incorporation”) and the Amended and Restated Bylaws of the Company, as amended, as presently in effect (the “Bylaws”), and that none of the terms of any Shares to be established after the date hereof, nor the issuance and delivery of such Shares, nor the compliance by the Company with the terms of such Shares will violate any applicable law or public policy or result in a violation of any provision of any instrument or agreement then binding upon the Company or any restriction imposed by any court or governmental body having jurisdiction over the Company.

On the basis of such examination, our reliance upon the assumptions in this opinion and our consideration of those questions of law we considered relevant, and subject to the limitations and qualifications in this opinion, we are of the opinion that when certificates representing the Shares in the form required under the California Corporations Code have been duly executed, countersigned, registered and delivered upon payment of the agreed upon consideration therefor, or, in the case of Shares issued in “street name,” the Shares have been entered on the books of the transfer agent and registrar under the names of the nominal owners, the issuance and sale of such Shares will have been duly authorized by all necessary corporate action on the part of the Company, and such Shares will be validly issued, fully paid and nonassessable and the Purchase Rights will be legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and under California law, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally (including, without limitation, fraudulent conveyance laws), and by general principles of equity including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law.

With respect to our opinion as to the Purchase Rights, we have assumed that, at the time of issuance and sale of the Shares, that the Rights Agreement has been duly authorized, executed and delivered by the Rights Agent and that the members of the Board of Directors have acted in a manner consistent with their fiduciary duties as required under applicable law in adopting the Rights Agreement. This opinion does not address the determination a court of competent jurisdiction may make regarding whether the Board of Directors of the Company would be required to redeem or terminate, or take other action with respect to, the Purchase Rights at some future time based on the facts and circumstances existing at that time. In addition, it should be understood that our opinion addresses the Rights Agreement and the Purchase Rights in their entirety and not any particular provision of the Rights Agreement or the Purchase Rights. It should also be understood that it is not settled whether the invalidity of any particular provision of a rights agreement or of rights issued thereunder would result in invalidating such rights in their entirety.

The law covered by this opinion is limited to the present law of the State of California and the State of New York. We express no opinion as to the laws of any other jurisdiction and no opinion regarding the statutes, administrative decisions, rules, regulations or requirements of any county, municipality, subdivision or local authority of any jurisdiction.

We hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the reference to this firm under the heading “Legal Matters” in the prospectus constituting part of the Registration Statement.

Respectfully submitted,
