BOARD OF DIRECTORS

Board of Directors Composition and Election of Directors

Our Board of Directors currently consists of five directors. Certain members of our Board of Directors were elected pursuant to the provisions of a voting agreement with certain holders of our preferred stock. The voting agreement terminated upon the closing of our initial public offering. Pursuant to our Certificate, as long as Hitachi Chemical Co., Ltd., or Hitachi owns at least 5% of the issued and outstanding shares of capital stock of the Company, Hitachi is entitled to elect one Class III director. Except for the rights of Hitachi and the rights of holders of preferred stock, if any, none of our stockholders will have any special rights regarding the election or designation of members of our Board of Directors.

Our Board of Directors consists of five members. In accordance with our Certificate our Board of Directors is divided into three classes.

Class II consists of Mr. Labrum and Mr. Chawla and Class III consists of Mr. Ashton. In the event Hitachi elects a director, such director will be a Class III director. All directors hold office until their successors have been elected and qualified or until their earlier death, resignation or removal. At each annual meeting of stockholders after the initial classification, the successors to directors whose terms will then expire will serve from the time of election and qualification until the third annual meeting following election and until their successors are duly elected and qualified. The number of directors to constitute the whole board of directors will consist of not fewer than three and not more than twelve directors, as fixed from time to time by resolution adopted by a majority of the entire Board of Directors. The section of our Amended and Restated Bylaws (“Bylaws”) relating to the size of our Board of Directors may not be altered, amended or repealed except by the board or by the affirmative vote of holders of at least two-thirds of our outstanding voting stock. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one third of the directors.

There are no family relationships among any of our directors or executive officers.

Code of Business Conduct and Ethics

Our Board of Directors has adopted a written Code of Business Conduct and Ethics applicable to our employees, officers and directors, including those officers responsible for financial reporting. The Code of Business Conduct and Ethics is available on our website at www.gbscience.com. We expect that any amendments to the code, or any waivers of its requirements, will be disclosed on our website.

Board Role in Risk Oversight

Our Board of Directors is responsible for overseeing the Company’s management of risk. The Board strives to effectively oversee the Company’s enterprise-wide risk management in a way that balances managing risks while enhancing the long-term value of the Company for the benefit of the stockholders. The Board of Directors understands that its focus on effective risk oversight is critical to setting the Company’s tone and culture towards effective risk management. To administer its oversight function, the Board seeks to understand the Company’s risk philosophy by having discussions with management to establish a mutual understanding of the Company’s overall appetite for risk. Our Board of Directors maintains an active dialogue with management about existing risk management processes and how management identifies, assesses, and manages the Company’s most significant risk exposures. Our Board expects frequent updates from management about the Company’s most significant risks so as to enable it to evaluate whether management is responding appropriately.

Our Board relies on each of its committees to help oversee the risk management responsibilities relating to the functions performed by such committees. Our Audit Committee periodically discusses with management the Company’s major financial risk exposures and the steps management has taken to monitor and control such exposures, including the Company’s risk assessment and risk management policies. Our Compensation Committee helps the Board to identify the Company’s exposure to any risks potentially created by our compensation programs and practices. Our Nominating and Corporate Governance Committee oversees risks relating to the Company’s corporate compliance programs and assists the Board and management in promoting an organizational culture that encourages commitment to ethical conduct and a commitment to compliance with the law. Each of these committees is required to make regular reports of its actions and any recommendations to the Board, including recommendations to assist the Board with its overall risk oversight function.

Director Compensation

Members of our Board of Directors who are our employees do not receive any fees for their service on our Board of Directors or for their service as a chair or committee member. Ryan Ashton is our only employee director. Our non-employee directors earned the following compensation for their service during our fiscal year ended December 31, 2014:

(3)	During 2014 Mr. Spafford was granted 75,000 stock options with a nominal fair value per share, which represents all of his outstanding option awards.

Ryan Ashton, our Chief Executive Officer, will not be receiving the fees set forth above.

Also, we adopted the 2014 Incentive Plan, which permits the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, and other stock-based awards.

Communications with Directors

We have not adopted a formal process for stockholder communications with the Board. We believe it is appropriate to not have a formal process for stockholder communications with the Board, because historically we have received such stockholder communications very infrequently. Nevertheless, we have tried to ensure that the views of stockholders are heard by the Board or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner. We believe our responsiveness to stockholder communications to the Board has been good. A stockholder may submit any communication with directors to us at our corporate offices, to the attention of Jeffrey Rona.

Master Lease Agreement with Onset and Related Warrants and Letters of Credit

We entered into a Master Lease Agreement to provide for the sale-leaseback of molecular diagnostic analyzers. We have completed two lease schedules under this lease agreement: Lease Schedule 001 dated October 16, 2013, amended December 10, 2013, for the sale of 125 molecular diagnostic analyzers for a purchase price of $2,500,000, which are being leased back for 36 monthly payments of $74,875 and Lease Schedule 002 dated March 14, 2014, amended March 18, 2014, for the sale of 75 molecular diagnostic analyzers for a purchase price of $1,500,000, which are being leased back for 24 monthly payments of $64,665. At the end of the lease term of Schedule 001, the lease will automatically renew for twelve additional months at the current monthly rate unless we give written notice 150 days prior to the end of the lease. If timely notice is given we have the opportunity to: 1) repurchase the analyzers for a purchase price determined by lessor not to exceed forty percent of the original costs; or 2) terminate the lease, return the property and enter into a new lease with new property that replaces the property of the old lease. Both we and the lessor will have the right to reject any terms of option 1 or 2 and if rejected, the 12 month extension will apply. Schedule 002 includes similar end of term options as found in Schedule 001, except that if we give timely notice, we have the option to purchase the analyzers at a price to be determined by lessor and us. Schedule 002 also includes a provision that during the first 14 months of the base period of the Schedule, provided there is no event of default and if we complete a successful capital raise, then lessor will use commercially acceptable best efforts to rewrite this Schedule 002 at more favorable terms. We are accounting for these transactions as a capital lease sale-leaseback in accordance with ASC 840 “Leases.”

Our obligations pursuant to the sale-leaseback agreement are secured by letters of credit obtained by Spring Forth Investments, LLC, an entity controlled by David Spafford, and Utah Autism Foundation, an entity for which

Mr. Spafford serves on the Board of Trustees and as a Founder Trustee, in an aggregate amount of $3,000,000. These letters of credit were issued by a bank for the benefit of the lessor. Pursuant to three reimbursement agreements we entered into with those entities in connection with the letters of credit, we have agreed to pay each of them 10% interest per annum on the total amount of the letter of credit. Under the reimbursement agreements, we are also obligated to reimburse those third parties for any draws made under the letters of credit. As of December 31, 2014, no draws on either letter of credit had taken place. Our obligations under the reimbursement agreements are secured by a security interest in all of our assets pursuant to security agreements effective the dates of the respective lease schedule.

Ryan Ashton, our chief executive officer, and David Spafford, one of our directors, each personally guaranteed our obligations under the sale-lease agreement. These guarantees cover “the full amount of liability for any amounts due” from us to Onset under the lease agreement. On November 25, 2013, we issued Mr. Ashton warrants to purchase 50,000 shares of common stock and Mr. Spafford warrants to purchase 50,000 shares of common stock, each in compensation for their personal guarantees of our obligations under the lease agreement, with an exercise price of $2.00 per share.

The foregoing constitutes a summary of the material terms of the lease documents and is qualified in its entirety by the full text of the lease documents, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part.

Voting Agreement

On February 16, 2010 we entered into a voting agreement under which certain holders of our preferred stock, including entities affiliated with certain of our directors, have agreed to vote in a certain way on certain matters, including with respect to the election of directors. In connection with the issuance of Series D Preferred Stock, the Voting Agreement was amended and restated on April 21, 2014 and July 30, 2014. Pursuant to the July 2014 amendment and restatement, (i) the parties agreed to vote their shares to set the size of the board at five directors, (ii) the holders of common stock, voting as a separate class, elect one director to our board (initially Ryan Ashton), and (iii) for long as Hitachi owns 5% of the issued and outstanding shares of the capital stock of the Company, Hitachi will be entitled to elect one director. Upon the closing of our initial public offering, the board election voting provisions contained in the voting agreement terminated; however, pursuant to the terms of the Series D Stock Purchase Agreement and our Certificate, Hitachi will continue to be entitled to elect one director.

Investor Rights Agreement

On February 16, 2010, we entered into an investor rights agreement with the holders of our outstanding Series A preferred stock, including entities affiliated with certain of our directors. On November 26, 2013, the investor rights agreement was amended in connection with the issuance of Series C Preferred Stock and Series C-1 Preferred Stock. On April 21, 2014, the investor rights agreement was amended in connection with the issuance of Series D Preferred Stock and on July 30, 2014 the investor rights agreement and was further amended in connection with the issuance of additional shares of Series D Preferred Stock.

Indemnification Provisions

We intend to enter into indemnification agreements with each of our directors and officers. These indemnification agreements, and our Certificate and Bylaws, require us to indemnify our directors and officers to the fullest extent permitted by Delaware law.

Policies and Procedures for Transactions with Related Persons

In the event that a related party transaction is identified, such transaction must be reviewed and approved or ratified by our Audit Committee. If it is impracticable for our Audit Committee to review such transaction, the transaction will be reviewed by the chair of our Audit Committee, whereupon the chair of our Audit Committee will report to the Audit Committee the approval or disapproval of such transaction.

In reviewing and approving related person transactions, the Audit Committee, or its chair, considers all information that the Audit Committee, or its chair, believes to be relevant and important to a review of the transaction. The Audit Committee or its chair, as the case may be, approves only those related person transactions that are determined to be in, or not inconsistent with, our best interests and that of our stockholders, taking into account all available relevant facts and circumstances available to the Audit Committee or the chair. These facts and circumstances will typically include, but not be limited to, the benefits of the transaction to us; the impact on a director’s independence in the event the related person is a director, an immediate family member of a director or an entity in which a director is a partner, stockholder or executive officer; the availability of other sources for comparable products or services; the terms of the transaction; and the terms of comparable transactions that would be available to unrelated third parties or to employees generally. No member of the Audit Committee will participate in any review, consideration or approval of any related person transaction with respect to which the member or any of his or her immediate family members is the related person.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act, requires our directors, officers, and persons that own more than 10 percent of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC. Officers, directors and greater than 10 percent stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

Based solely upon our review of the copies of such forms received by us during the year ended December 31, 2014, we believe that each person who, at any time during such year, was a director, officer, or beneficial owner of more than 10% of our common stock met the filing requirements during such year, except for a late Form 3 filing by Hitachi.

AUDIT COMMITTEE REPORT

The Audit Committee has reviewed and discussed our audited financial statements with our management and has discussed with Mantyla McReynolds LLC the matters required to be discussed by Statements of Auditing Standards No. 16, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

The Audit Committee has received the written disclosures and the letter from Mantyla McReynolds LLC required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accountant’s communications with the Audit Committee concerning independence, and has discussed with Mantyla McReynolds LLC its independence from us.

PROPOSAL 1: Election of Two Class I Directors

Overview

Our Certificate provides for a classified Board of Directors consisting of three classes of directors, each serving staggered three-year terms and each class as nearly equal in number as possible as determined by our Board of Directors. As a result, a portion of our Board of Directors will be elected each year. David Spafford has been designated a Class I director and his term expires at this Annual Meeting. Kirk Calhoun has not previously served on our Board of Directors, but if elected would be a Class I director. If elected, Mr. Spafford and Mr. Calhoun’s terms would expire at the annual meeting of stockholders to be held in 2018.

Mr. Spafford currently serves as members of our Board of Directors and has agreed to serve if elected. Mr. Calhoun has not served previously as a member of our Board of Directors but has agreed to serve if elected.

PROPOSAL 2: Approval and Adoption of Amendment to Seventh Amended and Restated Certificate of Incorporation

Overview

We are seeking stockholder approval to adopt an amendment to the Certificate (the “Amended Certificate”). We believe amending the Certificate is necessary in order to increase the number of authorized shares of common stock from 50,000,000 to 200,000,000.

The text of the proposed amendment to Article IV.A of the Certificate, marked to show changes from the current Certificate, is attached to this proxy statement asAppendix A and is incorporated herein by reference.

Description of Amended Certificate

If this proposal is approved by the Company’s stockholders, the first sentence of Article IV.A of the Certificate will be updated to read as follows:

The additionalyour shares of Common Stock that will be available for issuance will be identical in terms toat the shares of Common Stock currently authorized under the Certificate. The additionalSpecial Meeting (or any adjournments or postponements) as you have instructed on your proxy card. With proxy voting, your shares of Common Stock will be voted whether or not have preemptive rights.you attend the Special Meeting. Even if you plan to attend the Special Meeting, it is a good idea to complete, sign and return your proxy card in advance of the Special Meeting, just in case your plans change.

If an issue comes up for vote at the Special Meeting (or any adjournments or postponements) that is not described in this Proxy Statement, your representatives will vote your shares of Common Stock under your proxy, at their discretion, subject to any limitations imposed by law.

When is the Record Date?

The Board has fixed November 2, 2015 as the Record Date for the Special Meeting. Only holders of shares of Common Stock as of the close of business on that date will be entitled to vote at the Special Meeting.

How many shares of Common Stock are outstanding?

As of February 28,November 2, 2015, wethe Company had 5,086,458[190,679,941] shares of Common Stock issued and outstanding.

What am I voting on?

You are being asked to vote on the following:

How many votes do I get?

Each share of Common Stock is entitled to one vote. Dissenters’ rights are not applicable to any of the matters being voted upon.

The Board recommends a voteFORthe approval of the Reverse Stock Split,FORthe approval of the Authorized Share Increase, andFORthe approval of the Adjournment Proposal.

How do I vote?

You have several voting options. You may vote by:

If your shares of Common Stock are held in an account with a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of such shares held in a “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote the shares in your account. You are also invited to attend the Special Meeting. However, since you are not the stockholder of record, you may not vote your shares of Common Stock in person at the Special Meeting unless you request and obtain a valid proxy card from your broker, bank, or other nominee.

Can stockholders vote in person at the Special Meeting?

The Company will pass out written ballots to anyone who wants to vote at the Special Meeting. If you hold your shares of Common Stock through a brokerage account but do not have a physical share certificate, or the shares are registered in someone else’s name, you must request a legal proxy from your stockbroker or the registered owner to vote at the Special Meeting.

What if I change my mind after I return my proxy?

You may revoke your proxy and change your vote at any time before the polls close at the Special Meeting. You may do this by:

Beneficial stockholders should refer to the instructions received from their stockbroker or the registered holder of the shares of Common Stock if they wish to change their vote.

How many votes do you need to hold the Special Meeting?

To conduct the Special Meeting, the Company must have a quorum, which means that a majority of the outstanding voting shares of the Company as of the Record Date must be present at the Special Meeting. The Company’s Common Stock is the only type of security entitled to vote at the Special Meeting. Based on [190,679,941] shares of Common Stock outstanding as wellof the Record Date of November 2, 2015, [95,339,971] shares of Common Stock must be present at the Special Meeting, in person or by proxy, for there to be a quorum. Your shares of Common Stock will be counted as 29,652,040 shares reserved for issuancepresent at the Special Meeting if you:

What if I abstain from voting?

Abstentions with respect to a proposal are counted for the exercisepurposes of warrants to purchase sharesestablishing a quorum. Since the Reverse Stock Split and the Authorized Share Increase each require the affirmative vote of our Common Stock and 11,440,800 shares reserved for issuance for the conversiona majority of previously issued shares of Series E Convertible Preferred Stock.

As the number of issued andour outstanding shares of Common Stock and shares reserved for issuance is approaching the 50,000,000 limit in our Certificate, the Board believes that failure to approve this proposal would seriously restrict our ability to manage our capital needs and to take advantage of potential business opportunities,since, pursuant to the detriment of our stockholders’ interests. The Board believes additional authorized shares will allowCompany’s bylaws, the Company to act with flexibility when and as the need arises to issue additional shares in the future without the delays necessitated by having to obtain a stockholder vote (except as otherwise required by law orAdjournment Proposal must be approved by the rulesmajority of any securities exchange on which the shares of Common Stock are listed)present at the meeting, a properly executed proxy card markedABSTAIN with respect to any proposal at the Special Meeting will have the same effect as votingAGAINST that proposal.

What effect does a broker non-vote have?

Brokers and to take advantage of attractive business opportunities and changing market and financial conditions in a more timely manner.

We have no current plan, agreement or arrangement for the issuance of anyother intermediaries, holding shares of Common Stock other than under (i) already existing warrantsin street name for their customers, are generally required to purchase common stockvote such shares in the manner directed by their customers. If their customers do not give any direction, brokers may vote such shares on routine matters but not on non-routine matters. Our management believes that the Reverse Stock Split, the Authorized Share Increase and the Adjournment Proposal are routine matters. Consequently, if customers do not give any direction, brokers will be permitted to vote shares of Series E Convertible PreferredCommon Stock and (ii) our Stock Option Plan, our Amended and Restated 2014 Stock Option Plan, and our 2014 Omnibus Incentive Plan.at the Special Meeting in relation to these matters. However, the additional authorized shares would be available for issuance (subjectwe encourage you to further stockholder approval as required by law or by the rules of any securities exchange on which thesubmit your voting instructions to your broker to ensure your shares of Common Stock are listed)voted at such times and for such purposes as the Board may approve, including possible future financing transactions, acquisitions, stock dividends, and other general corporate purposes.Special Meeting.

If this proposal is approved and our Certificate is amended, the Board generally may issue such additional authorized

Any shares of our Common Stock without further stockholder approval, in return for such consideration in money, property,represented at the Special Meeting but not voted (whether by abstention, broker non-vote or other things of value asotherwise) with respect to the Board, in its discretion, will determine. In some instances, stockholder approval forproposals to approve the issuance of additional shares may be required by law or byReverse Stock Split, the requirements of The NASDAQ Capital Market, on which our Common Stock is now listed,Authorized Share Increase, or the obtaining ofAdjournment Proposal will have the same effect as a voteAGAINST such approvals may be otherwise necessary or desirable.

The Board has not proposedHow many votes are needed to approve the increase in the amount of authorized shares with the intention of discouraging tender offers or takeover attempts of the Company. However, the availability of additional authorized shares for issuance could discourage or render more difficult a merger, tender offer, proxy contest or other attempt to obtain control of the Company. Additionally, such issuance could have a dilutive effect on the equity, earnings, and voting interests of existing stockholders.

Effectiveness of Amendment

If the proposed Amended Certificate is adopted, it will become effective upon the filing of the Amended Certificate with the State of Delaware, which we expect to file shortly after receiving stockholder approval.

Request for Additional Shares and Dilution

The following table sets forth information regarding historical awards granted and earnedRecord Date for the fiscal 2012 through fiscal 2014 period, and the corresponding burn rate, which is defined as the number of shares subject to equity-based awards granted in a year divided by the weighted average common and preferred shares outstandingreasonable expenses incurred for that year, for eachmailing copies of the last three fiscal years. We have included preferred shares in this calculation as all preferred shares outstanding at the time of our initial public offering converted into common shares upon the completion of our initial public offering in October 2014.

A copy of the 2014 Incentive Plan is attached as Appendix B to this proxy statement. The following summary of the material terms of the 2014 Incentive Plan is qualified in its entirety by referencematerials to the full textbeneficial owners of the 2014 Incentive Plan.

Purpose.

The purpose of the 2014 Incentive Plan is to promote the interests of us and our stockholders by aiding us in attracting and retaining employees, officers, consultants, advisors and non-employee directors capable of assuring the future success of the Company, to offer such persons incentives to put forth maximum efforts for the success of our business and to compensate such persons through various stock and cash-based arrangements and provide them with opportunities for stock ownership in the Company, thereby aligning the interests of such persons with our stockholders.

Eligible Participants.Any employee, officer, non-employee director, consultant, independent contractor or consultant providing services to us or any of our affiliates, or any such person to whom an offer of employment or engagement with us or any of our affiliates is extended, is eligible to receive awards under the 2014 Incentive Plan.

Types of Awards Available Under the 2014 Incentive Plan.

The 2014 Incentive Plan permits the granting of:

Stock Options

The holder of an option will be entitled to purchase a number of shares of our common stock at a specified exercise price during a specified time period, all as determined by the administrator. The exercise price per share is the purchase price for each share of common stock that may be purchased pursuant to the option. Options may be designated as “incentive stock options,” which are intended to meet the requirements of Section 422 of the Code, or as “non-qualified stock options,” which are not intended to meet the requirements of Section 422. Options will vest and become exercisable in accordance with the vesting schedule established by the Compensation Committee of the Board and set forth in an award agreement. Under the 2014 Incentive Plan, the exercise price of stock options must be not less than 100% of the fair market value of the stock on the date of grant. Notwithstanding the foregoing, an incentive stock option granted to an eligible person who owns directly or indirectly more than 10% of our common stock will have an exercise price of not less than 110% of the fair market value of our common stock on the date of grant.

SARs

The holder of an SAR will be entitled to receive the excess of the fair market value of one share of our common stock (or other securities or property) on the date the SAR is exercised (or, if the Compensation Committee so provides, at any time during a specified period before or after the date of exercise) over the grant price of the

SAR. The Compensation Committee has the ability to determine the dates of exercise, methods of settlement and any other terms and conditions of the SARs. SARs will vest and become exercisable in accordance with the vesting schedule established by the Compensation Committee and set forth in the award agreement. The grant price of a SAR will be determined by the Compensation Committee, and may not be less than 100% of the fair market value of one share of our common stock (or other securities or property) on the date the SAR is granted (unless granted in substitution for an SAR previously granted by an acquired or merged entity). In its discretion, the Compensation Committee may impose conditions or restrictions on the exercise of any SAR.

Restricted Stock and Restricted Stock Units

Restricted Stock. The holder of restricted stock will own shares of our common stock subject to restrictions imposed by the Compensation Committee in its discretion for a specified time period determined by the Compensation Committee. The restrictions may include restrictions on transfer of the restricted stock, limitations on the right to vote or receive dividends with respect to the shares subject to the restricted stock award, and other restrictions as determined by the Compensation Committee. The restriction period begins on the date of grant of the restricted stock. The restrictions may lapse or be waived separately or collectively at such time or times, in installments or otherwise, as determined by the Compensation Committee and set forth in the award agreement. After the restrictions have lapsed, a holder of restricted stock will have all of the rights of a stockholder of our common stock with respect to the shares that have become unrestricted. If a holder’s employment or service with the Company terminates during the applicable restriction period, the restricted stock will be forfeited, unless the Compensation Committee determines otherwise, or as otherwise provided in the award agreement.

Restricted Stock Units. The holder of restricted stock units will have the right, subject to any restrictions imposed by the Compensation Committee, to receive shares of our common stock promptly following the lapse or waiver of such restrictions. The restriction period relating to the restricted stock units will begin on the date of grant of the restricted stock units. If a holder’s employment or service with the Company terminates during the applicable restriction period, the restricted stock units will be forfeited, unless the Compensation Committee determines otherwise, or as otherwise provided in the award agreement.

Performance Awards

The Compensation Committee may grant performance awards payable in cash, shares of common stock, or other awards, securities or property, upon the achievement of specified performance goals during a specified period of time as established by the Compensation Committee. These awards are intended to be “qualified performance-based compensation” within the meaning of Section 162(m) of the Code. The performance goals that must be met, the length of any performance period, the amounts to be paid if the performance goals are met, the certification of the achievement of the performance goals, and any other terms or conditions of each performance award will be determined by the Compensation Committee.

Dividend Equivalents

The Compensation Committee may grant dividend equivalents payable in cash, shares of common stock or other awards, securities or property, as determined in the discretion of the Compensation Committee, equivalent to the amount of cash dividends paid by us to holders of shares with respect to a number of shares determined by the committee. Subject to the terms of the 2014 Incentive Plan, the terms and conditions of each dividend equivalents will be determined by the Compensation Committee. However, in no case will dividend equivalents be granted in connection to (i) option or SAR grants or (ii) performance awards prior to the performance-based vesting conditions being satisfied, waived or lapsed.

Other Stock-Based Awards

The committee may grant other awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, shares of our common stock (including securities convertible

into shares of our common stock) or other securities, in compliance with applicable law. The Compensation Committee will determine the terms and conditions of any such awards. If the other stock-based award is a right to purchase shares or other securities, the purchase price and the method and form of payment will be determined by the Compensation Committee.

Performance Goals under the 2014 Incentive Plan.

The performance goals under the 2014 Incentive Plan will be based upon one or more of the following performance measures, applied either individually, alternatively or in any combination, applied on a corporate, subsidiary, division, business unit or line of business basis: economic value added (EVA); sales or revenue; costs or expenses; net profit after tax; gross profit; income (including without limitation operating income, pre-tax income and income attributable to the Company); cash flow (including without limitation free cash flow and cash flow from operating, investing or financing activities or any combination thereof); earnings (including without limitation earnings before or after taxes, earnings before interest and taxes (EBIT), earnings before interest, taxes, depreciation and amortization (EBITDA) and earnings (whether before or after taxes), EBIT or EBITDA as a percentage of net sales); earnings per share (EPS) (basic or diluted); earnings per share from continuing operations; returns (including one or more of return on actual or pro forma assets, net assets, equity, investment, revenue, sales, capital and net capital employed, total shareholder return (TSR) and total business return (TBR)); margins (including one or more of gross, operating and net income margin); ratios (including one or more of price to earnings, debt to assets, debt to net assets and ratios regarding liquidity, solvency, fiscal capacity, productivity or risk); budget comparisons; unit volume; stock price; net working capital; value creation; market share; market capitalization; workforce satisfaction and diversity goals; employee retention; production metrics; development; implementation or completion of key projects; strategic plan development and implementation.

Each performance goal mentioned above may be based (i) solely by reference to absolute results of individual performance or organizational performance at various levels (e.g., the Company’s performance or the performance of a subsidiary, division, business segment or business unit of the Company) or (ii) upon organizational performance relative to the comparable performance of other companies selected by the Compensation Committee. To the extent consistent with Section 162(m) of the Code, the Compensation Committee may, when it establishes performance criteria, also provide for the exclusion of charges related to an event or occurrence which the Compensation Committee determines should appropriately be excluded, including(x) asset-write downs, litigation or claim judgments or settlements, reorganizations, the impact of acquisitions and divestitures, restructurings, discontinued operations, extraordinary items, and other unusual ornon-recurring charges, (y) foreign exchange gains and losses or an event either not directly related to the operations of the Company or not within the reasonable control of the Company’s management, or (z) the cumulative effects of tax or accounting changes in accordance with U.S. generally accepted accounting principles (or other accounting principles which may then be in effect). To the extent that Section 162(m) of the Code or applicable tax and/or securities laws change to permit Compensation Committee discretion to alter the governing performance measures without disclosing to stockholders and obtaining stockholder approval of such changes and without thereby exposing the Company to potentially adverse tax or other legal consequences, the Compensation Committee has the sole discretion to make such changes without obtaining stockholder approval.

Limits on Awards under the 2014 Incentive Plan.

Aggregate Award Limitations

The aggregate number of shares of Common Stock that may be delivered under the 2014 Incentive Plan is currently 500,000 plus any shares of Common Stock subject to outstanding awards as of September 5, 2014, under the Great Basin Scientific, Inc. Amended and Restated 2014 Stock Option Plan and the Great Basin Scientific, Inc. Stock Option Plan (together, the “Prior Plans”), that are subsequently forfeited or terminated for any reason before being exercised. However, if Proposal 3 is approved by our Stockholders, the aggregate number of shares of Common Stock that may be delivered under the 2014 Incentive Plan will increase to

2,940,000 and the amount of shares available for grant under the 2014 Incentive Plan would adjust automatically on the first day of each fiscal quarter to an amount equal to the greater of (i) fifteen percent (15%) of the number of shares of Common Stock outstanding on the last day of the immediately preceding fiscal quarter or (ii) 2,940,000 shares of Common Stock.

All shares available for grant

What materials accompany or are subjectattached to adjustment in the event of stock splits, stock dividends and other capital changes. If any award under the 2014 Incentive Plan or Prior Plans terminates without having been exercised in full, or if any award under the 2014 Incentive Plan or Prior Plans is satisfied in cash rather than Common Stock, the number of shares of Common Stock as to which the award was not exercised or for which cash was substituted will be available for future grants. No fractional shares may be issued under the 2014 Incentive Plan.

Individual Award Limitations

No eligible person under the 2014 Incentive Plan may be granted any stock options, SARs or performance awards denominated in shares, for more than 250,000 shares (subject to certain adjustments), in the aggregate in any calendar year.

The maximum amount payable pursuant to all performance awards denominated in cash to any participant in the 2014 Incentive Plan in the aggregate in any calendar year shall be $1,000,000 in value. This limitation does not apply to any award or awards subject to the limitation contained in the paragraph above. However, no director who is not also an employee of the Company or an affiliate of the Company may be granted any award or awards denominated in shares that exceed in the aggregate $250,000 (such value computed as of the date of grant in accordance with applicable financial accounting rules) in any calendar year. The foregoing limit shall not apply to any award made pursuant to any election by the director to receive an award in lieu of all or a portion of annual and committee retainers and annual meeting fees.

Certain Federal Income Tax Consequences

The following is a summary of the principal U.S. federal income tax consequences generally applicable to awards made under the 2014 Incentive Plan.

Grant of Options and SARs. The grant of a stock option (either an incentive stock option or a non-qualified stock option) or SAR is not expected to result in any taxable income for the recipient.

Exercise of Incentive Stock Options. No taxable income is realized by the optionee upon the grant or exercise of an incentive stock option. The holder of an incentive stock option generally will have no taxable income upon exercising the option (except that an alternative minimum tax liability may arise), and we will not be entitled to an income tax deduction. If stock is issued to the optionee pursuant to the exercise of an incentive stock option, and if no disqualifying disposition of such shares is made by such award holder within two years after the date of grant or within one year after the transfer of such shares to such award holder, then (1) upon the sale of such shares, any amount realized in excess of the option price will be taxed to such optionee as a long-term capital gain and any loss sustained will be a long-term capital loss, and (2) we will not be entitled to a deduction for federal income tax purposes.

If the stock acquired upon the exercise of an incentive stock option is disposed of prior to the expiration of either holding period described above, generally (1) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of such shares at exercise (or, if less, the amount realized on the disposition of such shares) over the option price paid for such shares, and (2) we will be entitled to deduct such amount for federal income tax purposes if the amount represents an ordinary and necessary business expense. Any further gain (or loss) realized by the optionee will be taxed as short-term or long-term capital gain (or loss), as the case may be, and will not result in any deduction by us.

Exercise of Non-Qualified Stock Options and SARs. Upon exercising a non-qualified stock option, the optionee must recognize ordinary income equal to the excess of the fair market value of the shares of our common stock acquired on the date of exercise over the exercise price, and we generally will be entitled at that time to an income tax deduction for the same amount. Upon exercising a SAR, the amount of any cash received and the fair market value on the exercise date of any shares of our common stock received are taxable to the recipient as ordinary income and generally are deductible by us.

The tax consequence upon a disposition of shares acquired through the exercise of an option or SAR will depend on how long the shares have been held and whether the shares were acquired by exercising an incentive stock option or by exercising a non-qualified stock option or SAR. Generally, there will be no tax consequence to us in connection with the disposition of shares acquired under an option or SAR, except that we may be entitled to an income tax deduction in the case of the disposition of shares acquired under an incentive stock option before the applicable incentive stock option holding periods set forth in the Internal Revenue Code have been satisfied.

Restricted Stock. Recipients of grants of restricted stock generally will be required to include as taxable ordinary income the fair market value of the restricted stock at the time it is no longer subject to a substantial risk of forfeiture. However, an award holder who makes an 83(b) election within thirty days of the date of grant of the restricted stock will incur taxable ordinary income on the date of grant equal to the fair market value of such shares of restricted stock (determined without regard to forfeiture restrictions). With respect to the sale of shares after the forfeiture restrictions have expired, the holding period to determine whether the award recipient has long-term or short-term capital gain or loss generally begins when the restrictions expire and the tax basis for such shares will generally be based on the fair market value of the shares on that date. However, if the award holder made an 83(b) election as described above, the holding period commences on the date of such election and the tax basis will be equal to the fair market value of the shares on the date of the election (determined without regard to the forfeiture restrictions on the shares). Dividends, if any, that are paid or accrued while the restricted stock is subject to a substantial risk of forfeiture will also be taxed as ordinary income. We will be entitled to an income tax deduction equal to amounts the award holder includes in ordinary income at the time of such income inclusion.

Restricted Stock Units, Performance Awards and Dividend Equivalents. Recipients of grants of restricted stock units, performance awards or dividend equivalents (collectively, “deferred awards”) will not incur any federal income tax liability at the time the awards are granted. Award holders will recognize ordinary income equal to (a) the amount of cash received under the terms of the award or, as applicable, (b) the fair market value of the shares received (determined as of the date of receipt) under the terms of the award. Dividend equivalents received with respect to any deferred award will also be taxed as ordinary income. Cash or shares to be received pursuant to a deferred award generally become payable when applicable forfeiture restrictions lapse; provided, however, that, if the terms of the award so provide, payment may be delayed until a later date to the extent permitted under applicable tax laws. We will be entitled to an income tax deduction for any amounts included by the award holder as ordinary income. For awards that are payable in shares, a participant’s tax basis is equal to the fair market value of the shares at the time the shares become payable. Upon the sale of the shares, appreciation (or depreciation) after the shares are paid is treated as either short-term or long-term capital gain (or loss) depending on how long the shares have been held.

Other Stock Grants. As to other grants of shares of our common stock made under the 2014 Incentive Plan not subject to a substantial risk of forfeiture, the holder of the award must recognize ordinary income equal to the excess of (i) the fair market value of the shares received (determined as of the date of receipt) over (ii) the amount (if any) paid for the shares by the holder of the award. We generally will be entitled at that time to an income tax deduction for the same amount.

Special Rules. Special rules may apply in the case of individuals subject to Section 16 of the Securities Exchange Act of 1934. In particular, unless a special election is made pursuant to Section 83(b) of the Code, shares of our common stock received pursuant to the exercise of an option or SAR may be treated as restricted as to transferability and subject to a substantial risk of forfeiture for a period of up to six months after the date of exercise. Accordingly, the amount of any ordinary income recognized, and the amount of our tax deduction, may be determined as of the end of such period.

Deductibility of Executive Compensation Under Code Section 162(m). Section 162(m) generally limits to $1,000,000 the amount that a publicly-held corporation is allowed each year to deduct for the compensation paid to each of the corporation’s “covered employees”, which include the chief executive officer and the corporation’s other three most highly compensated executive officers other than the chief financial officer. However, “qualified performance-based compensation” is not subject to the $1,000,000 deduction limit. In general, to qualify as performance-based compensation, the following requirements need to be satisfied: (1) payments must be computed on the basis of an objective, performance-based compensation standard determined by a committee consisting solely of two or more “outside directors,” (2) the material terms under which the compensation is to be paid, including the business criteria upon which the performance goals are based, and a limit on the maximum

bonus amount which may be paid to any participant with respect to any performance period, must be approved by a majority of the corporation’s stockholders and (3) the committee must certify that the applicable performance goals were satisfied before payment of any performance-based compensation.

The 2014 Incentive Plan has been designed to permit grants of options and SARs issued under the 2014 Incentive Plan to qualify under the performance-based compensation rules so that income attributable to the exercise of a non-incentive stock option or an SAR may be exempt from $1,000,000 deduction limit. Grants of performance awards made to Covered Employees under the 2014 Incentive Plan also qualify for this exemption. The 2014 Incentive Plan’s provisions are consistent in form with the performance-based compensation rules, so that if the committee that grants options, SARs or performance awards to Covered Employees consists exclusively of members of our board of directors who qualify as “outside directors,” and the exercise price (or deemed exercise price, with respect to SARs) is not less than the fair market value of the shares of our common stock to which such grants relate, the compensation income arising on exercise of those options or SARs should qualify as performance-based compensation which is deductible even if that income would be in excess of the otherwise applicable limits on deductible compensation income under Section 162(m).

Overview of Proposal 3

On April 13, 2015 the Board approved and made the following amendments to the 2014 Incentive Plan (as proposed to be amended in this Proposal 3, the “Amended 2014 Incentive Plan”):

A copy of the Amended 2014 Incentive Plan is attached to this proxy statement asAppendix B, which is marked to show changes from the previously approved 2014 Incentive Plan, is attached to this proxy statement asAppendix B and is incorporated herein by reference.

The Board approved the 2014 Incentive Plan on September 5, 2014, pursuant to which 500,000 shares of Common Stock were reserved for issuance pursuant to the grant of stock awards to employees, officers, consultants, advisors andnon-employee directors. Options are granted at an exercise price determined by the Compensation Committee of the Board of Directors, which, unless a substitute award, may not be less than the fair market value of the stock on the date of grant. Vesting terms and expiration are also approved by the Compensation Committee. Under the 2014 Incentive Plan, approximately 363,216 shares were available for future option grants as of February 28, 2015.

As of February 28, 2015, the Board of Directors has authorized the grant of a total of 703,034 stock options, having a total fair value of approximately $1.8 million, with certain options fully vested and the remaining options having remaining vesting periods ranging from three to four years. These options expire between February 14, 2020 and December 12, 2024.

We expect this proposal would allow us to continue to grant equity to our employees in connection with our annual incentive compensation, long-term incentive awards, and hiring and retention efforts for the duration of the 2014 Incentive Plan’s ten-year term, consistent with our past practices and the recent trading price of our shares of Common Stock.

Description of Amendment to the 2014 Incentive Plan

If this Proposal 3 is approved by the Company’s stockholders, Section 4(a) of the 2014 Incentive Plan will be updated to read as follows:

In addition, if the proposal is approved by the Company’s stockholders, Section 6(a)(iv)(A) of the 2014 Incentive Plan will be updated to read as follows:

Overview of Proposal 4

In order for the Company to continue to make awards under the 2014 Incentive Plan that qualify as “performance-based compensation” that is exempt from the $1 million deduction limit imposed by Section 162(m) of the Internal Revenue Code of 1986 (the “Code”), the 2014 Incentive Plan (and in particular, the material terms thereof, including the performance measures on which performance goals may be based and the individual dollar limitations on payments in any calendar year) must be approved by the stockholders of the Company.

Section 162(m) of the Code (“Section 162(m)”) generally does not allow a publicly held company to obtain a tax deduction for compensation of more than $1,000,000 paid in any fiscal year to certain “covered employees” unless, among other exceptions, such compensation is considered “performance-based” in accordance with Section 162(m). Under Section 162(m) as currently interpreted by the Internal Revenue Service, the group of “covered employees” as of the end of any taxable year consists of a company’s chief executive officer and its three other most highly compensated executive officers, other than the chief financial officer. The 2014 Incentive Plan is designed to permit the Compensation Committee to issue awards that qualify as “performance-based” under Section 162(m), provided the procedures associated with them comply with all of the requirements of Section 162(m). 2014 Incentive Plan awards other than options and stock appreciation rights, referred to as “full value awards,” will only be treated as qualified performance-based compensation under Section 162(m) if the awards are conditioned upon the achievement of certain performance goals during a specified performance period.

Among the requirements that must be satisfied if compensation provided under the 2014 Incentive Plan in connection with full value awards is to qualify as performance-based compensation under Section 162(m) is that the material terms under which the compensation is to be paid, specifically the nature of the performance goals and the maximum amounts that may be paid to any employee, must be approved by our stockholders. Section 162(m) also requires that such material terms must be re-approved by our stockholders at least every five years.

The nature of the performance goals (“Performance Goals”) is discussed more fully above in the Description of the 2014 Incentive Plan under “Performance Goals under the 2014 Incentive Plan.” The annual limit on share-denominated awards and cash-denominated awards intended to represent “qualified performance-based awards” are described above under “Limits on Awards under the 2014 Incentive Plan.”Shareholder approval of the Performance Goals for purposes of awards intended to qualify as performance-based compensation under Section 162(m) includes approval of the business criteria on which performance goals are based and the maximum awards that may be made to any individual

If the Performance Goals are approved, the Company will be able to structure annual and other incentive awards in a manner that should qualify for the performance-based compensation exemption from the deduction limitations of Section 162(m) of the Code. However, neither the 2014 Incentive Plan nor this Proxy Statement is intended to ensure that the compensation we pay to our executive officers or other employees qualifies as performance-based compensation. There are a number of requirements that must be met in order for particular compensation to qualify as performance-based compensation and, as such, there can be no assurance that such compensation under the 2014 Incentive Plan will be fully deductible under all circumstances. Moreover, there is no guarantee that the terms of the 2014 Incentive Plan or the compensation provided pursuant thereto will comply with the requirements of performance-based compensation. In addition, other awards under the 2014 Incentive Plan may or may not qualify depending on the terms of the awards and we currently have, and intend to retain, the ability to provide compensation that is not exempt from the Section 162(m) deductibility limits.

Vote Required

A majority of the votes present in person or represented by proxy at the Annual Meeting is required to approve each of Proposal 3 and Proposal 4. Abstentions will have the same effect as votes against the proposals. Broker non-votes will have no effect on the vote for the proposals.

The Board of Directors unanimously recommends that the stockholders of the company voteFOR the amendments to the 2014 Incentive Plan to (i) expand the aggregate number of shares of Common Stock that may be issued under all awards under the plan from 500,000 to 2,940,000, including a similar increase in the number of shares of Common Stock that may be issued under all incentive stock options under the 2014 Incentive Plan, to account for the additional shares of Common Stock underlying our Series E Convertible Preferred Stock, and (ii) add an evergreen provision to the plan whereby the amount of shares of common stock available under the plan will adjust automatically each fiscal quarter.

The Board of Directors unanimously recommends that the stockholders of the company voteFOR the approval of the performance measures available under the 2014 Incentive Plan for the purpose of complying with section 162(m) of the Code.

                    , 2015

APPENDIX A

Proposed Amendment toamend Article IV.A of the Seventh Amended and Restated Certificate of Incorporation (such amendment as shown in Appendix B) to effect a reverse stock split of our issued and outstanding shares of Common Stock at a ratio and effective upon a date to be determined by the Board and effect a corresponding change in the par value of our of shares of Common Stock from $0.001 to $0.0001 (the “Reverse Stock Split”).

Why did the Board approve the Reverse Stock Split?

Reverse Stock Split

We have received a delisting notice from The NASDAQ Stock Market. Our Common Stock may be involuntarily delisted from trading on The NASDAQ Capital Market if we fail to regain compliance with (i) the minimum closing bid price requirement of $1.00 per share of Common Stock and (ii) the market value of listed securities requirement of $35 million. A delisting of our Common Stock is likely to reduce the liquidity of our Common Stock and may inhibit or preclude our ability to raise additional financing and may also materially and adversely impact our credit terms with our vendors.

The textquantitative listing standards of The NASDAQ Stock Market, or NASDAQ, require, among other things, that listed companies maintain a minimum closing bid price of $1.00 per share and maintain a minimum value of listed securities of $35 million. We failed to satisfy the minimum bid price threshold and the minimum value of listed securities threshold for 30 consecutive trading days and on October 14, 2015, we received a letter from NASDAQ indicating our deficiency and that we have been provided an initial period of 180 calendar days, or until April 11, 2016, in which to regain compliance.

If the Company does not regain compliance within the 180-day grace period, it may be eligible to receive an additional 180-day grace period; provided that the Company meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market including the minimum market value of listed securities of $35 million, with the exception of the proposed amendmentbid price requirements, and provides written notice of its intention to cure the bid price deficiency during the second 180-day grace period, by effecting a reverse stock split, if necessary. This additional 180-day grace period does not apply to the Company’s deficiency regarding the minimum value of listed securities.

Par Value Change

Our Board believes that the change to $0.0001 par value Common Stock will provide the Company with additional flexibility in utilizing its shares of common stock for various corporate purposes. Par value is used to designate the lowest value for which a company can legally sell its shares. Historically, the concept of par value was to protect creditors and senior security holders by ensuring that when issuing its own shares a company received at least par value as consideration for the shares. As markets have become more liquid, with stock prices responding more rapidly to market developments, par value has become a generally outdated concept. Instead, for public companies like us, the market sets the price at which stock may be issued or otherwise sold. The reduction in par value will have no impact on the value of the Company’s stock or the rights of its stockholders. The change in par value to $0.0001 per share will give the Company greater flexibility for structuring future transactions and making future financial decisions.

What is the purpose of the Reverse Stock Split?

Reverse Stock Split

If we do not regain compliance by April 11, 2016, and we do not qualify or are not granted an additional 180-day grace period in which to regain compliance, the NASDAQ staff will provide written notice that our Common Stock is subject to delisting.

Given the increased market volatility, the challenging environment in our industry and our lack of liquidity, we may be unable to regain compliance with the closing bid price requirement within our 180-day grace period. A delisting of our Common Stock is likely to reduce the liquidity of our Common Stock and may inhibit or preclude our ability to raise additional financing and may make it difficult for our stockholders to sell any securities if they desire or need to sell them.

The Board has considered the potential harm to the Company and our stockholders should NASDAQ delist our Common Stock. Delisting from NASDAQ would adversely affect our ability to raise additional financing through the public or private sale of equity securities and would significantly affect the ability of investors to trade our securities. Delisting would also likely negatively affect the value and liquidity of our Common Stock because alternatives, such as the OTC Bulletin Board and the pink sheets, are generally considered to be less efficient markets.

We believe that the Company’s best option to meet NASDAQ’s $1.00 minimum bid price requirement before the end of our initial 180-day grace period is to effect the Reverse Stock Split to increase the per-share trading price of our Common Stock. Given the volatility and fluctuations in the capital markets, the Board believes that the likelihood of our stock price increasing to meet the NASDAQ listing requirements within the 180-day grace period without the Reverse Stock Split is remote and that the Company likely will have to take additional actions to comply with NASDAQ requirements.

If our stockholders do not approve the Reverse Stock Split, the Company may be delisted from the NASDAQ Capital Market due to our failure to maintain a minimum bid price for our Common Stock of $1.00 per share as required by the NASDAQ Marketplace Rules.

Even if the Company effects the Reverse Stock Split, the Company may still be subject to delisting if the Company fails to meet the minimum value of listed securities requirement by April 11, 2016.

Par Value Change

Our board of directors believes that the decrease in par value of our Common Stock is our best interests and the best interests of our stockholders because it will bring the par value in line with the par value of other similar companies and will provide our Board and our management with more flexibility in setting the consideration that may be received for shares of Common Stock in purchases and sales and other corporate transactions, although no such transactions are currently contemplated.

In addition, under the DGCL, the aggregate par value must be deducted from the amount available for dividends (the result being “surplus,” out of which dividends can be paid). While we have no current plans to pay dividends on our Common Stock or Series E Preferred Stock, we could in the future decide to pay cash dividends. Accordingly, the reduction in par value contemplated by this proposal would increase our surplus for DGCL purposes, and therefore our potential dividend paying ability.

What amendments are being made to the Certificate of Incorporation?

The first paragraph of Article IV.A of the Seventh Amended and Restated Certificate of Incorporation marked to show changes to the current Article IV.A, is set forthwhich currently reads as follows:

“ARTICLE IV.A

The total number of shares of capital stock the Corporation is authorized to issue isFifty-Five Million (55,000,000) Two-Hundred Two Hundred and Five Million (205,000,000) shares, consisting ofFifty Two Hundred Million (50,000,000) Two-Hundred Million (200,000,000) shares of common stock, par value $0.001 per share (the “Common Stock”), and Five Million (5,000,000) shares of preferred stock, par value $0.001 per share (“Preferred Stock”).”

shall be amended to read as follows:

“APPENDIX BARTICLE IV.A

The full texttotal number of shares of capital stock the Corporation is authorized to issue is Two Hundred and Five Million (205,000,000) shares, consisting of Two Hundred Million (200,000,000) shares of common stock, par value $0.0001 per share (the “Common Stock”), and Five Million (5,000,000) shares of preferred stock, par value $0.001 per share (“Preferred Stock”).”

Note that if the Authorized Share Increase under Proposal 2 is approved and implemented, the number of authorized shares of Common Stock will also be amended.

The following paragraph will be added to Article IV.A of the 2014 Incentive Plan, including marked changesCertificate of Incorporation:

“Upon the effectiveness of this Certificate of Amendment to show the proposed amendments to Sections 4(a) and 6(a)(iv)(A), is set forth as follows:

GREAT BASIN SCIENTIFIC, INC.

2014 OMNIBUS INCENTIVE PLAN

Section 1. Purpose

The purposeCertificate of Incorporation of the PlanCorporation, every [number of shares] shares of the Corporation’s issued and outstanding Common Stock, par value $0.001 per share, that are issued and outstanding immediately prior to [date] shall, automatically and without any further action on the part of the Corporation or the holder thereof, be combined into one (1) validly issued, fully paid and non-assessable share of the Corporation’s Common Stock, par value $0.0001 per share, provided that in the event a stockholder would otherwise be entitled to a fraction of a share of Common Stock pursuant to the provisions of this Article, such stockholder shall receive one whole share of Common Stock in lieu of such fractional share and no fractional shares shall be issued.”

Does the Board recommend approval of the Reverse Stock Split?

Yes. After considering the entirety of the circumstances, the Board has unanimously concluded that the Reverse Stock Split is to promotein the best interests of the Company and its stockholders and the Board unanimously recommends that the Company’s stockholders vote in favor of the Reverse Stock Split.

What vote is required to approve the Reverse Stock Split?

The affirmative vote of the holders of a majority of the outstanding shares of our Common Stock is required to amend the Certificate of Incorporation to effect the Reverse Stock Split. Failures to vote and abstentions will be the equivalent of a vote against this proposal.

Material Effects of the Proposed Reverse Stock Split

Upon the effectiveness of the amendment to our Certificate of Incorporation effecting the Reverse Stock Split, the outstanding shares of our Common Stock will be combined into a lesser number of shares such that one share of our Common Stock will be issued for a specified number of shares, which number shall be equal to or greater than 50 and equal to or less than 60, of outstanding shares of our Common Stock, with the exact number within such range to be determined by aiding the CompanyBoard prior to the effective time of such amendment. In connection with the Reverse Stock Split, any fractional shares that would otherwise be issued as a result of the Reverse Stock Split will be rounded up to the nearest whole share. Even if stockholder approval of the Reverse Stock Split is obtained, the Board may abandon the Reverse Stock Split in attracting and retaining employees, officers, consultants, advisors andnon-employee Directors capable of assuringits sole discretion if it determines that the future successReverse Stock Split is no longer in the best interests of the Company and its stockholders.

The Reverse Stock Split will not change the number of authorized shares of our Common Stock (see Proposal 2 regarding the Authorized Share Increase). The Reverse Stock Split will change the par value of our Common Stock from $0.001 to offer$0.0001.

The Reverse Stock Split will affect all holders of our Common Stock uniformly and will not affect any stockholder’s percentage ownership interest in the Company (subject to the treatment of fractional shares). In

addition, the Reverse Stock Split will not affect any holder of Common Stock’s proportionate voting power (subject to the treatment of fractional shares).

Based on our shares of Common Stock outstanding as of the Record Date, the principal effects of the Reverse Stock Split will be that the number of shares of our Common Stock issued and outstanding will be reduced from [190,679,941] shares as of the Record Date to a range of [3,813,599] shares (if a 1-for-50 ratio is chosen) to [3,177,999] shares (if a 1-for-60 ratio is chosen), depending on the exact exchange ratio chosen by the Board and without giving effect to any rounding up of fractional shares.

The table below sets forth, as of [November 2], 2015 and for illustrative purposes only, certain effects of the potential ratios of between 50-for-1 and 60-for-1, inclusive, including on our total outstanding Common Stock equivalents (without giving effect to the treatment of fractional shares).

As illustrated by the table above, the Reverse Stock Split would significantly increase the number of authorized and unissued shares of Common Stock available to settle the exercise or conversion, of our outstanding derivative securities and avoid the penalties associated with being unable to settle such persons incentivesconversions and exercises. In addition, the Reverse Stock Split would significantly increase the ability of our Board to put forth maximum effortsissue authorized and unissued shares in future equity financings.

In determining which ratio to implement, if any, following receipt of stockholder approval, our Board may consider, among other things, various factors such as:

The principal effects of the Reverse Stock Split will be as follows:

Possible Anti-Takeover Implications of the Reverse Stock Split

The issuance in the future of additional shares of our Common Stock made available by the Reverse Stock Split may have the effect of diluting the earnings or loss per share and book value per share, as well as the ownership and voting rights of the holders of our then-outstanding shares of Common Stock. In addition, an increase in the number of authorized but unissued shares of our Common Stock due to the Reverse Stock Split may have a potential anti-takeover effect, as our ability to issue additional shares could be used to thwart persons, through various stock andcash-based arrangements and provide them with opportunities foror otherwise dilute the stock ownership inof stockholders, seeking to control us. Further, the ability to issue our shares of Common Stock at a lower price may afford the Company thereby aligningadded flexibility to deter a potential takeover of the interests of such persons withCompany by diluting the Company’s stockholders.

Section 2. Definitions

As used in the Plan, the following terms shall have the meanings set forth below:

(a) “Affiliate” shall mean any entityshares held by a potential suitor or issuing shares to a stockholder that directly or indirectly through one or more intermediaries, is controlled by the Company.

(b) “Award” shall mean any Option, Stock Appreciation Right, Restricted Stock, Restricted Stock Unit, Performance Award, Dividend Equivalent or Other Stock-Based Award granted under the Plan.

(c) “Award Agreement” shall mean any written agreement, contract or other instrument or document evidencing an Award granted under the Plan (including a document in an electronic medium) executedwill vote in accordance with the Board’s desires at a very low par value. A takeover may be beneficial to independent stockholders because, among other reasons, a potential suitor may offer such stockholders a premium for their shares of Common Stock compared to the then-existing market price. The Reverse Stock Split is not being recommended by our Board as part of an anti-takeover strategy.

Reservation of Right to Delay the Filing of, or Abandon, the Reverse Stock Split and Par Value Change

If stockholder approval is obtained to effect the Reserve Stock Split, the Board expects to select an appropriate ratio and implement the Reverse Stock Split on or before February 28, 2016. However, the Board reserves the authority to decide, in its sole discretion, to delay or abandon the Reverse Stock Split after such vote and before the effectiveness of the Reverse Stock Split if it determines that the Reverse Stock Split is no longer in the best interests of the Company and its stockholders.

The Board will also consider whether the Authorized Share Increase (see Proposal 2 below) is approved and implemented in determining whether to effect the Reverse Stock Split. The Board will, however, implement the Reverse Stock Split, if at all, prior to February 28, 2016.

Fractional Shares

Our stockholders will not receive fractional post-Reverse Stock Split shares in connection with the Reverse Stock Split. Instead, any fractional shares that would otherwise be issuable as a result of the Reverse Stock Split will be rounded up to the nearest whole share. No stockholders will receive cash in lieu of fractional shares.

No Going Private Transaction

The Reverse Stock Split is not intended as, and will not have the effect of, a “going private transaction” covered by Rule 13e-3 under the U.S. Exchange Act. Following the Reverse Stock Split, the Company will continue to be subject to the periodic reporting requirements of Section 9(b).

(d) “Board” shall mean the BoardSecurities Exchange Act of Directors of the Company.

(e) “Code” shall mean the Internal Revenue Code of 1986,1934, as amended from time to time, and any regulations promulgated thereunder.

(f)(the “Committee” shall mean the Compensation Committee of the Board or such other committee designated by the Board to administer the Plan.

(g) “Company” shall mean Great Basin Scientific, Inc. and any successor corporation.

(h) “Director” shall mean a member of the Board.

(i) “Dividend Equivalent” shall mean any right granted under Section 6(e) of the Plan.

(j) “Eligible Person” shall mean any employee, officer,non-employee Director, consultant, independent contractor or advisor providing services to the Company or any Affiliate, or any such person to whom an offer of employment or engagement with the Company or any Affiliate is extended.

(k) “Exchange Act” shall mean).

Effective Time

The proposed Reverse Stock Split would become effective as of 12:01 a.m., Eastern Time (the “Effective Time”) on the Securities Exchange Actdate specified in the amendment to the Certificate of 1934,Incorporation effecting the Reverse Stock Split as amended.

(l) “Fair Market Value”filed with the office of the Secretary of State of Delaware. Except as explained above with respect to fractional shares, at the Effective Time, shares of our Common Stock issued and outstanding immediately prior thereto will be combined, automatically and without any action on the part of our stockholders, into one Shareshare of our Common Stock in accordance with the ratio of between 1 for 50 and 1 for 60.

After the Effective Time, our Common Stock will have a new committee on uniform securities identification procedures (“CUSIP”) number, which is a number used to identify our equity securities, and stock certificates with the older CUSIP numbers will need to be exchanged for stock certificates with the new CUSIP numbers by following the procedures described below.

After the Effective Time, we will continue to be subject to periodic reporting and other requirements of the Exchange Act. Unless our Common Stock is delisted by NASDAQ because of our failure to comply with the $1.00 minimum bid price requirement or the minimum value of listed securities, our Common Stock will continue to be listed on The NASDAQ Capital Market under the symbol “GBSN.”

Procedures for effecting the Reverse Stock Split and Exchange of Stock Certificates

If the Company’s stockholders approve the Reverse Stock Split and the Board determines that it is in the Company’s best interest to effect the Reverse Stock Split, the Reverse Stock Split would become effective at such time as the amendment to the Certificate of Incorporation, the form of which is attached asAppendix B to this Proxy Statement, is filed with the Secretary of State of Delaware or such time and date as stated therein when filed.

As soon as practicable after the effective date of the Reverse Stock Split, the Company will notify its stockholders that the Reverse Stock Split has been implemented. American Stock Transfer & Trust Company, the Company’s transfer agent, will act as exchange agent for purposes of implementing the exchange of stock certificates. Holders of pre-Reverse Stock Split shares of our Common Stock will be asked to surrender to the exchange agent certificates representing pre-Reverse Stock Split shares of our Common Stock in accordance with the procedures to be set forth in a letter of transmittal that will be delivered to the Company’s common stockholders. No new certificates will be issued to a stockholder until the stockholder has surrendered to the exchange agent his, her or its outstanding certificate(s) together with the properly completed and executed letter of transmittal. STOCKHOLDERS SHOULD NOT DESTROY ANY STOCK CERTIFICATES AND SHOULD NOT SUBMIT ANY CERTIFICATES UNTIL REQUESTED TO DO SO. Stockholders whose shares are held by their stockbroker do not need to submit old share certificates for exchange. These shares will automatically reflect the new quantity of shares based on the Reverse Stock Split. Beginning on the effective date of the

Reverse Stock Split, each certificate representing pre-Reverse Stock Split shares will be deemed for all corporate purposes to evidence ownership of post-Reverse Stock Split shares.

Effect on Registered and Beneficial Holders of Common Stock

Upon the effectiveness of the Reverse Stock Split, shares of our Common Stock held by stockholders that hold their shares through a broker or other nominee will be treated in the same manner as shares held by registered stockholders that hold their shares in their names. Brokers and other nominees that hold shares of our Common Stock will be instructed to effect the Reverse Stock Split for the beneficial owners of such shares. However, those brokers or other nominees may implement different procedures than those to be followed by registered stockholders for processing the Reverse Stock Split. Stockholders whose shares of our Common Stock are held in the name of a broker or other nominee are encouraged to contact their broker or other nominee with any questions regarding the procedure of implementing the Reverse Stock Split with respect to their shares.

Effect on Registered “Book-Entry” Holders of Our Common Stock

Registered holders of shares of our Common Stock may hold some or all of their shares electronically in book-entry form under the direct registration system for the securities. Those stockholders will not have stock certificates evidencing their ownership of shares of our Common Stock, but generally have a statement reflecting the number of shares registered in their accounts.

Stockholders that hold registered shares of our Common Stock in book-entry form do not need to take any action to receive post-Reverse Stock Split shares. Any such stockholder that is entitled to post-Reverse Stock Split shares will automatically receive, at the stockholder’s address of record, a transaction statement indicating the number of post-Reverse Stock Split shares held following the implementation of the Reverse Stock Split.

Dissenters’ Rights

Our stockholders will not be entitled to dissenters’ rights with respect to the proposed amendment to the Certificate of Incorporation in connection with the Reverse Stock Split.

No Effect on Authorized Preferred Stock

Pursuant to our Certificate of Incorporation, our capital stock consists of a total of 205,000,000 authorized shares, of which 200,000,000 shares, par value $0.001 per share, are designated as Common Stock and 5,000,000 shares, par value $0.001 per share, are designated as preferred stock. The proposed Reverse Stock Split would not impact the total authorized number of shares of preferred stock or the par value of the preferred stock.

Effect on Dividends

The payment of dividends, including the timing and amount dividends, must be made in accordance with our Certificate of Incorporation and the requirements of the Delaware General Corporation Law (the “DGCL”). We cannot assure you that any dividends will be paid in the future on the shares of Common Stock. Any declaration and payment of future dividends to holders of our Common Stock will be at the discretion of our Board and will depend on many factors, including our financial condition, earnings, capital requirements, level of indebtedness, statutory future prospects and contractual restrictions applicable to the payment of dividends, and other considerations that our Board deems relevant. The decrease in par value may affect our ability to make dividend payments. Under the DGCL, the aggregate par value must be deducted from the amount available for dividends (the result being “surplus,” out of which dividends can be paid). Accordingly, the reduction in par value contemplated by this proposal would increase our surplus for DGCL purposes, and therefore our potential dividend paying ability.

Accounting Matters

The Reverse Stock Split will change the par value of the shares of our Common Stock and the number of shares of Common Stock issued and outstanding. As a result, as of the effective time of the Reverse Stock Split, the stated capital attributable to the shares of our Common Stock on our balance sheet will be reduced proportionately based on the ratio chosen by the Board for the Reverse Stock Split to reflect the new number of shares outstanding and the new par value, and the additional paid-in capital account will be credited with the amount by which the stated capital is reduced. The per share net income or loss will be restated because there will be fewer shares of Common Stock outstanding.

Effect on Our Preferred Shares, Options and Warrants

If the Reverse Stock Split is effected, the number of shares of Common Stock issuable upon exercise or conversion of our outstanding preferred shares, stock options (including shares reserved for issuance under the Company’s stock plans) and warrants will be proportionately adjusted by the applicable administrator, using the ratio as the Reverse Stock Split, rounded up to the nearest whole share. In connection with the Reverse Stock Split, the Board or the applicable administrator will implement only applicable technical, conforming changes to the securities, including ratably reducing the authorized shares of Common Stock available for awards under the Company’s stock plans. In addition, the conversion price for each outstanding preferred shares and the exercise price for each outstanding stock option and warrant would be increased in inverse proportion to the split ratio such that upon an conversion or exercise, the aggregate conversion price for conversion of preferred stock and the aggregate exercise price payable by the optionee or warrantholder to the Company for the shares subject to the option or warrant would remain approximately the same as the aggregate exercise price prior to the Reverse Stock Split.

Interests of Directors and Executive Officers

Our directors and executive officers do not have substantial interests, directly or indirectly, in the matters set forth in this proposal except to the extent of their ownership of shares of our Common Stock or any other of our securities.

Certain Material U.S. Federal Income Tax Consequences of the Reverse Stock Split

The following is a summary of material United States federal income tax consequences of the Reverse Stock Split to holders of our Common Stock. Except where noted, this summary deals only with our Common Stock that is held as a capital asset.

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and United States Treasury regulations, rulings and judicial decisions as of the date shall mean (a)hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below.

This summary does not address all aspects of United States federal income taxes that may be applicable to holders of Common Stock and does not deal with non-U.S., state, local or other tax considerations that may be relevant to stockholders in light of their particular circumstances. In addition, it does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws (including if you are a dealer in securities or currencies; a financial institution; a regulated investment company; a real estate investment trust; an insurance company; a tax-exempt organization; a person holding shares as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle; a trader in securities that has elected the mark-to-market method of accounting for your securities; a person liable for alternative minimum tax; a person who owns or is deemed to own 10% or more of our voting stock; a partnership or other pass-through entity for United States federal income tax purposes; a person whose “functional currency” is not the United States dollar; a United States expatriate; a “controlled foreign corporation”; or a “passive foreign investment company”).

We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary. No ruling from the Internal Revenue Service or opinion of counsel will be obtained regarding the federal income tax consequences to stockholders as a result of the Reverse Stock Split.

If a partnership (or other entity treated as a partnership for United States federal income tax purposes) holds our Common Stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our Common Stock, you should consult your own tax advisors.

We believe that the Reverse Stock Split, if implemented, would be a tax-free recapitalization under the Code. If the Reverse Stock Split qualifies as a tax-free recapitalization under the Code, then, generally, for United States federal income tax purposes, no gain or loss will be recognized by the Company in connection with the Reverse Stock Split, and no gain or loss will be recognized by stockholders that exchange their shares of pre-split Common Stock for shares of post-split Common Stock. The post-split Common Stock in the hands of a stockholder following the Reverse Stock Split will have an aggregate tax basis equal to the aggregate tax basis of the pre-split Common Stock held by that stockholder immediately prior to the Reverse Stock Split. A stockholder’s holding period for the post-split Common Stock generally will be the same as the holding period for the pre-split Common Stock exchanged therefor.

Alternative characterizations of the Reverse Stock Split are possible. For example, while the Reverse Stock Split, if implemented, would generally be treated as a tax-free recapitalization under the Code, stockholders whose fractional shares resulting from the Reverse Stock Split are rounded up to the nearest whole share may recognize gain for United States federal income tax purposes equal to the value of the additional fractional share. However, we believe that, in such case, the resulting tax liability may not be material in view of the low value of such fractional interest. Stockholders should consult their own tax advisors regarding the characterization of the Reverse Stock Split for United States federal income tax purposes.

Certain Risks Associated with the Reverse Stock Split

The Board believes that the Reverse Stock Split will increase the price level of our shares of Common Stock and, as a result, may enable the Company to maintain listing of our Common Stock on The NASDAQ Capital Market. Given the volatility and fluctuations in the capital markets, however, the Board believes that the likelihood of our stock price increasing to meet the NASDAQ listing requirements within the 180-day grace period without the Reverse Stock Split is remote and that the Company likely will have to take additional actions to comply with NASDAQ requirements. There are a number of risks associated with the Reverse Stock Split, including as follow:

THE BOARD RECOMMENDS A VOTE “FOR” THE AMENDMENT OF THE CERTIFICATE OF INCORPORATION TO EFFECT THE REVERSE STOCK SPLIT.

PROPOSAL 2—AUTHORIZED SHARE INCREASE

Introduction

Our Board has unanimously determined that it is in the best interests of the Company and our stockholders to amend Article IV.A of the Certificate of Incorporation (such amendment as shown inAppendix B) to increase the number of authorized shares of Common Stock by 750,000,000 shares from 200,000,000, par value $0.001, to 950,000,000, par value $0.001.

Why did the Board approve the Authorized Share Increase?

As of November 2, 2015, there were no shares of unissued and unreserved Common Stock available for issuance under our authorized capital. Because the Company’s authorized share capital is currently 200,000,000 shares of Common Stock, we have insufficient shares to cover our obligations unless the Company’s stockholders approve either the Authorized Share Increase or the Reverse Stock Split. As of [November 2,] 2015, there were [190,679,941] shares of Common Stock outstanding, [792,534] shares reserved for future issuance pursuant to issued options under our stock based employee compensation plans, [2,703,716] shares reserved for future issuance of options under our 2014 Omnibus plan and [417,944] shares reserved upon the conversion of our Series E Convertible Preferred Stock. Additionally, there were [362,520,622] shares issuable upon exercise of warrants issued and outstanding, including our Series C Warrants. Based on the price of our Common Stock on [November 2,] 2015 of [$0.0866], we would need [329,338,911] shares of Common Stock to settle the cashless exercise of all outstanding Series C Warrants.

What is the purpose of the Authorized Share Increase?

The Board recommends the Authorized Share Increase for the following reasons:

Why doesn’t the Company have sufficient shares of Common Stock to issue shares of Common Stock upon the exercise of the Series C Warrants?

On February 25, 2015, we sold 2,724,000 units (“Units”) in a public offering. Each Unit consisted of one Shareshare of Series E Convertible Preferred Stock and eight Series C Warrants. Each share of Series E Convertible Preferred Stock is convertible into four shares of Common Stock at the closeoption of the regular trading sessionholder. The Series C Warrants may be exercised for cash at an exercise price of $2.55 or on a cashless basis pursuant to a formula disclosed therein. On June 23, 2015, the Series C Warrants were amended and restated in order to allow certain early exercises.

As of 9:00 AM on September 21, 2015, we had 73,820,468 shares of authorized and unissued shares of Common Stock available for issuance pursuant to the Series C Warrants, which number of authorized and unissued shares of Common Stock was not sufficient to satisfy all exercises that we received on that day and although we allocated shares of Common Stock to permit the exercise of some of the Series C Warrants, such shares were insufficient and we had to stop accepting exercises of the Series C Warrants. Pursuant to the terms of the Series C Warrants, at such time as the Company no longer has sufficient authorized and unissued shares of Common Stock to settle the exercises of the Series C Warrants, the Series C Warrants shall not be exercisable into shares of Common Stock unless and until we obtain stockholder approval for the Authorized Share Increase.

What could happen if the stockholders do not approve the Authorized Share Increase?

If the stockholders approve the Authorized Share Increase, does the Company have plans for future issuances of shares of Common Stock?

Given the Company’s current available capital, its cash and cash equivalents, its history of operating at a loss and its need for additional capital to implement its plan of operations, the Company currently anticipates that it will be required to commence an offering of its equity securities in the near future. As of the date of this Proxy Statement, the Company has not entered into any formal agreements with respect to the securities it might offer or the terms and conditions of such offering, but the Company anticipates that the securities it offers might consist of units, shares of Common Stock, Common Stock purchase warrants, convertible debt or other derivative securities of the Company. Such securities would be offered at a price negotiated at arm’s length under the current market conditions at the time of pricing.

The Company is also currently contemplating its options in relation to the settlement of the Series C Warrants, which might include a private or public restructuring of the terms of the Series C Warrants or the private or public exchange of the Series C Warrants for other equity or debt securities of the Company. As of the date of this Proxy Statement, the Company has not entered into any agreement with respect to a potential restructuring or exchange onoffer involving the Series C Warrants and there can be no assurance that such date, as reported by The Wall Street Journalrestructuring or exchange offer will occur.

We do not believe that we currently have sufficient available capital to fully execute our current strategy through December 31, 2015, particularly if we are required to pay cash penalties for the failure to settle the conversions and exercises.

Our current strategy involves significant efforts to expand our customer base and increase our number of available tests and assays. To potentially become profitable, we will need to significantly increase our revenues. We do not expect that sales will increase sufficiently to cover our total costs of operations in 2015. We believe additional funding will be required in the near term. It is likely that such funding would require authorized shares beyond what is currently authorized without effecting either the Authorized Share Increase or the Reverse Stock Split. This Proxy Statement does not constitute an offer of any securities for sale or a comparable reporting service,solicitation of an offer to buy any securities.

Approval of the Authorized Share Increase will provide us with the necessary flexibility to raise capital and restructure our capital using equity, if and when the opportunities arise.

If the Authorized Share Increase is approved and we engage in one or if no salemore transactions involving the issuance of Shares shall have occurred on our equity securities, current stockholders of the Company may be substantially diluted as a result of

such date, on the next preceding date on which there was a salefuture issuances. The amount of Shares; (b)potential dilution will be even greater if the SharesReverse Stock Split is approved and implemented by the Board. See “Proposal 1—Reverse Stock Split” above.

What amendments are not so listed on any established stock exchange,being made to the averageCertificate of Incorporation?

The first paragraph of Article IV.A of the closing “bid”Certificate of Incorporation which currently reads as follows:

“ARTICLE IV.A

The total number of shares of capital stock the Corporation is authorized to issue is Two Hundred and “asked” prices quoted byFive Million (205,000,000) shares, consisting of Two Hundred Million (200,000,000) shares of common stock, par value $0.001 per share (the “Common Stock”), and Five Million (5,000,000) shares of preferred stock, par value $0.001 per share (“Preferred Stock”).”

shall be amended to read as follows:

“ARTICLE IV.A

The total number of shares of capital stock the OTC Bulletin Board, the National Quotation Bureau, or any comparable reporting service on such date or, if there are no quoted “bid”Corporation is authorized to issue is Nine Hundred and “asked” prices on such date, on the next preceding date for which there are such quotes for a Share; or (c)Fifty-Five Million (955,000,000) shares, consisting of Nine Hundred and Fifty Million (950,000,000) shares of common stock, par value $0.001 per share (the “Common Stock”), and Five Million (5,000,000) shares of preferred stock, par value $0.001 per share (“Preferred Stock”).”

Note that if the Shares are not publicly traded as of such date, the per share value of a Share, as determinedReverse Stock Split under Proposal 1 is approved and implemented by the Board, the par value of the Common Stock of $0.001 will also be amended to $0.0001.

Does the Board recommend approval of the Authorized Share Increase?

Yes. After considering the entirety of the circumstances, the Board has unanimously concluded that the Authorized Share Increase is in the best interests of the Company and its stockholders and the Board unanimously recommends that the Company’s stockholders vote in favor of the Authorized Share Increase.

What vote is required to approve the Authorized Share Increase?

The affirmative vote of the holders of a majority of the outstanding shares of our Common Stock is required to amend our Certificate of Incorporation to effect the Authorized Share Increase. Failures to vote, abstentions and broker “non-votes”, if any, will be the equivalent of a vote AGAINST this proposal.

IF OUR STOCKHOLDERS DO NOT APPROVE THE AUTHORIZED SHARE INCREASE, THE BOARD BELIEVES THAT THE LONG-TERM FINANCIAL VIABILITY OF THE COMPANY COULD BE THREATENED DUE TO (I) THE PENALTIES INCURRED FROM FAILURE TO SETTLE THE EXERCISES OF THE SERIES C WARRANTS AND (II) THE COMPANY’S INABILITY TO CONSUMMATE FUTURE EQUITY OFFERINGS TO MEET ITS ONGOING EXPENSES. SOME OF THESE CONSEQUENCES MAY BE MITITGATED IF THE REVERSE STOCK SPLIT IS APPROVED AND IMPLEMENTED.

Possible Anti-Takeover Implications of the Authorized Share Increase

The Company has no intent or plan to employ the additional unissued authorized shares as an anti-takeover device. As indicated above, the purpose of the Authorized Share Increase is to ensure that we have sufficient authorized Common Stock to, among other things, consummate future equity financings and attempt to mitigate risk in connection with the exercise of the Series C Warrants. However, the Company’s authorized but unissued shares of Common Stock could (within the limits imposed by applicable law, regulation and NASDAQ rules) be issued in one or more transactions that could make a change of control more difficult and therefore more unlikely.

Our Board did not propose the Authorized Share Increase in response to any effort known to our Board to accumulate Common Stock or to obtain control of the Company by means of a merger, tender offer or solicitation in opposition to management. Further, our Board does not currently contemplate recommending the adoption of any other amendments to our Certificate of Incorporation that could be construed as limiting the ability of third parties to take over or effect a change of control.

The issuance in the future of additional authorized shares of Common Stock may have the effect of diluting the earnings or loss per share and book value per share, as well as the ownership and voting rights of the holders of our then-outstanding shares of Common Stock. In addition, an increase in the number of authorized but unissued shares of Common Stock may have a potential anti-takeover effect, as our ability to issue additional shares could be used to thwart persons, or otherwise dilute the stock ownership of stockholders, seeking to control us. The Authorized Share Increase is not being recommended by our Board as part of an anti-takeover strategy.

No Effect on Authorized Preferred Stock

Pursuant to our Certificate of Incorporation, our capital stock consists of a total of 205,000,000 authorized shares, of which 200,000,000 shares, par value $0.001 per share, are designated as Common Stock and 5,000,000 shares, par value $0.001 per share, are designated as preferred stock. The proposed Authorized Share Increase would not impact the total authorized number of shares of preferred stock or the par value of the preferred stock.

Effect on Dividends

The payment of dividends, including the timing and amount dividends, must be made in accordance with our Certificate of Incorporation and the requirements of the DGCL. We cannot assure you that any dividends will be paid in the future on the shares of Common Stock. Any declaration and payment of future dividends to holders of our Common Stock will be at the discretion of our Board and will depend on many factors, including our financial condition, earnings, capital requirements, level of indebtedness, statutory future prospects and contractual restrictions applicable to the payment of dividends, and other considerations that our Board deems relevant.

Interests of Directors and Executive Officers

Our directors and executive officers do not have substantial interests, directly or indirectly, in the matters set forth in this proposal except to the extent of their ownership of shares of our Common Stock or any duly authorized Committeeother of our securities.

Reservation of Right to Delay the Filing of, or Abandon the Authorized Share Increase

We reserve the right to delay the filing of, or abandon, the Authorized Share Increase without further action by our stockholders at any time before February 28, 2016, even if the Authorized Share Increase has been approved by our stockholders at the Special Meeting. By voting in favor of the Authorized Share Increase, you are expressly also authorizing our Board to delay (until February 28, 2016) or abandon the Authorized Share Increase if it determines, in its sole discretion, by applying principles of valuation with respect thereto.

(m) “Incentive Stock Option” shall mean an option granted under Section 6(a) ofthat such action is in the Plan that is intended to meet the requirements of Section 422 of the Code or any successor provision.

(n) “Non-Qualified Stock Option” shall mean an option granted under Section 6(a) of the Plan that is not intended to be an Incentive Stock Option.

(o) “Option” shall mean an Incentive Stock Option or aNon-Qualified Stock Option to purchase shares of the Company.

(p) “Participant” shall mean an Eligible Person designated to be granted an Award under the Plan.

(q) “Performance Award” shall mean any right granted under Section 6(d) of the Plan.

(r) “Performance Goal” shall mean one or more of the following performance goals, either individually, alternatively or in any combination, applied on a corporate, subsidiary, division, business unit or line of business basis:

Each such Performance Goal may be based (i) solely by reference to absolute results of individual performance or organizational performance at various levels (e.g., the Company’s performance or the performance of a subsidiary, division, business segment or business unit of the Company) or (ii) upon organizational performance relative to the comparable performance of other companies selected by the Committee. To the extent consistent with Section 162(m), the Committee may, when it establishes performance criteria, also provide for the exclusion of charges related to an event or occurrence which the Committee determines should appropriately be excluded, including(X) asset-write downs, litigation or claim judgments or settlements, reorganizations, the impact of acquisitions and divestitures, restructurings, discontinued operations, extraordinary items, and other unusual ornon-recurring charges, (Y) foreign exchange gains and losses or an event either not directly related to the operationsbest interests of the Company or not withinand its stockholders.

The Board will consider whether the reasonable controlReverse Stock Split (see Proposal 1 above) is approved and implemented in determining whether to effect the Authorized Share Increase.

Effective Date

Delaware law and our Certificate of Incorporation require stockholder approval of the Company’samendment effecting the Authorized Share Increase. If the amendment is approved by a majority of the outstanding shares entitled to vote thereon and our Board determines to proceed with the Authorized Share Increase, we will amend Article IV.A to increase the number of authorized Common Stock as described above. The Authorized Share Increase will become effective upon the filing of the Authorized Share Increase with the Delaware Secretary of State. The only change in our Certificate of Incorporation to effect the Authorized Share Increase would be the numeric change required to reflect the increase of the number of authorized shares of our Common Stock.

No Dissenters’ Rights

Our stockholders are not entitled to dissenters’ rights in connection with the Authorized Share Increase. Furthermore, we do not intend to independently provide our stockholders with any such rights.

THE BOARD RECOMMENDS A VOTE “FOR” THE AMENDMENT OF THE CERTIFICATE OF INCORPORATION TO EFFECT THE AUTHORIZED SHARE INCREASE.

PROPOSAL 3—ADJOURNMENT PROPOSAL

Introduction

In this Adjournment Proposal, we are asking you to authorize the holder of any proxy solicited by the Board to vote in favor of adjourning, postponing or continuing the Special Meeting and any later adjournments. If the stockholders approve the Adjournment Proposal, we could adjourn, postpone or continue the Special Meeting, and any adjourned session of the Special Meeting, to use the additional time to solicit additional proxies in favor of the Reverse Stock Split and/or the Authorized Share Increase. Among other things, approval of the Adjournment Proposal could mean that, even if proxies representing a sufficient number of votes against the Reverse Stock Split and/or the Authorized Share Increase have been received, we could adjourn, postpone or continue the Special Meeting without a vote on the Reverse Stock Split and/or the Authorized Share Increase and seek to convince the holders of those shares to change their votes to votes in favor of the Authorize Share Increase and/or the Reverse Stock Split.

What vote is required to approve the Adjournment Proposal?

The Adjournment Proposal will be approved if a majority of the shares of Common Stock present in person or by proxy votesFORthe proposal. Accordingly, abstentions and broker non-votes, if any, will be counted as votesAGAINST the Adjournment Proposal. No proxy that is specifically markedAGAINST the Reverse Stock Split and/or the Authorized Share Increase will be voted in favor of the Adjournment Proposal, unless it is specifically marked FOR the discretionary authority to adjourn, postpone or continue the Special Meeting to a later date.

Why am I being asked to vote on the Adjournment Proposal?

The Board believes that if the number of shares of Common Stock present or represented at the Special Meeting and voting in favor of the proposal to Authorized Share Increase and/or the Reverse Stock Split are insufficient to approve such proposals, it is in the best interests of the stockholders to enable the Board, for a limited period of time, to continue to seek to obtain a sufficient number of additional votes to approve the amendment.
