This prospectus provides you with a general description of the securities we may offer. This prospectus does not contain all the information set forth in the registration statement as permitted by the rules of the SEC. Each time we offer securities, we will provide a supplement to this prospectus that will contain specific information about the terms of the offering and the offered securities. That prospectus supplement may also add, update or change information contained in this prospectus. Any statement that we make in this prospectus will be modified or superseded by any inconsistent statement made by us in a prospectus supplement. Before purchasing any securities, you should carefully read both this prospectus and any applicable prospectus supplement, together with the additional information described in this prospectus under the headings “Where You Can Find More Information” and “Incorporation by Reference.”

You should rely only on the information contained in this prospectus and in any applicable prospectus supplement, including any information incorporated by reference. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. You should not assume that the information appearing in this prospectus, any prospectus supplement or any document incorporated by reference is accurate at any date other than as of the date of each such document. Our business, financial condition, results of operations and prospects may have changed since the date indicated on the cover page of such documents.

The distribution of this prospectus may be restricted by law in certain jurisdictions. You should inform yourself about and observe these restrictions. This prospectus does not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which the offer or solicitation is not authorized, or in which the person making the offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make the offer or solicitation.

When used in this prospectus or in any supplement to this prospectus, the terms “GulfSlope,” “we,” “our,” “us,” or “the Company” refer to GulfSlope Energy, Inc. and its subsidiaries, unless otherwise indicated or the context otherwise requires.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information in this prospectus, including information in documents incorporated by reference, contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act of 1934, as amended (the “Exchange Act”). All statements, other than statements of historical facts, included in this prospectus, any prospectus supplement and the documents incorporated by reference herein and therein, are forward looking statements, including, without limitation, statements regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management. These forward-looking statements may be, but are not always, identified by their use of terms and phrases such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “project,” “plan,” “will,” “shall,” “should,” and similar terms and phrases, including when used in the negative. Although we believe that the expectations reflected in these forward-looking statements are reasonable, they do involve certain assumptions, risks and uncertainties. Actual results could differ materially from those anticipated in these forward-looking statements. You should consider carefully the risks described under the "Risk Factors" section of this prospectus, as well as the risks described in our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and the other disclosures contained or incorporated by reference herein and therein, which describe factors that could cause our actual results to differ from those anticipated in the forward-looking statements. All forward-looking statements are expressly qualified in their entirety by the cautionary statements in this paragraph and elsewhere in this prospectus and the documents incorporated by reference. Other than as required under the securities laws, we do not assume a duty to update these forward-looking statements, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.

THE COMPANY

The Company has leased 21 federal Outer Continental Shelf blocks (referred to as “prospect,” “portfolio” and “leases” in this prospectus) and licensed 2.2 million acres of three-dimensional (3-D) seismic data in its area of concentration.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making a decision to invest in our securities, you should carefully consider the risks described under “Risk Factors” in the applicable prospectus supplement and in our most recent Annual Report on Form 10-K, and any updates in our Quarterly Reports on Form 10-Q, together with all of the other information appearing or incorporated by reference into this prospectus and any applicable prospectus supplement. These risks are the material risks of which we are currently aware; however, they may not be the only risks that we may face. Additional risks and uncertainties not currently known to us or that we currently view as immaterial may also impair our business operations. Any of these risks could materially and adversely affect our business, prospects, financial condition and results of operations. In that case, you may lose all or part of your investment.

USE OF PROCEEDS

Unless we state otherwise in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities we are offering for general corporate purposes. This may include, among other things, the acquisition of assets, businesses or securities, capital expenditures, repaying all or a portion of our existing debt, and additions to our working capital. Any specific allocation of the net proceeds of an offering of securities to a specific purpose will be determined at the time of the offering and will be described in an accompanying prospectus supplement.

RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED DIVIDENDS

The following table sets forth our ratios of earnings to combined fixed charges and preferred dividends for each of the periods indicated.

	Nine Months Ended June 30, 2014	Year Ended September 30,
	Nine Months Ended June 30, 2014	2013	2012
Ratio of earnings to combined fixed charges and preference securities dividends (1)	−−(2)	−−(3)	−−(4)
Deficiency of earnings to cover fixed charges	$ (4,702,742)	$ (17,452,513)	$ (1,537,275)

______________________

(1)

For purposes of determining the ratio of combined fixed charges and preference dividends to earnings, earnings are defined as income before income taxes, plus fixed charges (excluding amortization of capitalized interest) less capitalized interest. Fixed charges consist of interest incurred (whether expensed or capitalized) and amortization of deferred financing costs. Preference dividends represent the amount of pre-tax earnings that are required to pay the dividends on outstanding preference securities, which is computed as the amount of the dividend divided by (1 minus the effective income tax rate applicable to continuing operations). No preferred dividends were paid for the periods shown.

(2)	For the nine months ended June 30, 2014, earnings were insufficient to cover fixed charges by $ (4,702,742).

(3)	For the fiscal year ended September 30, 2013, earnings were insufficient to cover fixed charges by $ (17,452,513).

(4)	For the fiscal year ended September 30, 2012, earnings were insufficient to cover fixed charges by $ (1,537,275).

DESCRIPTION OF OUR CAPITAL STOCK

We are authorized to issue 975,000,000 shares of common stock, par value $0.001, of which 660,672,345 shares are issued and outstanding as of November 12, 2014. We are also authorized to issue 50,000,000 shares of preferred stock, par value $0.001, none of which have been issued as of November 12, 2014.

Common Stock

The holders of common stock are entitled to one vote per share with respect to all matters required by law to be submitted to stockholders. The holders of common stock have the sole right to vote, except as otherwise provided by law or by our certificate of incorporation, including provisions governing any preferred stock. The common stock does not have any cumulative voting, preemptive, subscription or conversion rights. Election of directors requires the affirmative vote of a plurality of shares represented at a meeting, and other general stockholder action requires the affirmative vote of a majority of shares represented at a meeting in which a quorum is represented. All outstanding shares of common stock are fully paid and non-assessable, and the shares of common stock that will be issued under this prospectus will be fully paid and non-assessable.

At our 2014 annual meeting, our stockholders approved one or a series of reverse splits of the Company’s outstanding shares of common stock at a ratio of not less than 1-for-2 and not greater than 1-for-15. The exact ratio for such reverse split will be determined by our board of directors without further approval or authorization of the Company’s stockholders, provided that our board of directors determines to effect the reverse stock split and any amendments to the Company’s certificate of incorporation are filed with the Delaware Secretary of State (if necessary) no later than April 30, 2015.

Subject to the rights of any outstanding shares of preferred stock, the holders of common stock are entitled to receive dividends, if declared by our board of directors, out of funds legally available. In the event of liquidation, dissolution or winding up of the affairs of the Company, the holders of common stock are entitled to share ratably in all assets remaining available for distribution to them after payment or provision for all liabilities and any preferential liquidation rights of any preferred stock then outstanding.

Preferred Stock

Our certificate of incorporation authorizes our board of directors, subject to any limitations prescribed by law, without further stockholder approval, to establish and to issue from time to time one or more classes or series of preferred stock. As of the date of this prospectus, there were no shares of preferred stock issued and outstanding.

Each class or series of preferred stock will cover the number of shares and will have the powers, preferences, rights, qualifications, limitations and restrictions determined by the board of directors, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights, preemptive rights and redemption rights. Except as provided by law or in a preferred stock designation, the holders of preferred stock will not be entitled to vote at or receive notice of any meeting of stockholders.

The particular terms of any series of preferred stock being offered by us under this shelf registration statement will be described in the prospectus supplement relating to that series of preferred stock. Those terms may include:

the class, series title or designation and stated value (if any);

the maximum number of shares of offered preferred stock in such series, the liquidation preference per share and the offering price per share for such series;

the dividend preferences and the dividend rates, periods and/or payment dates or methods of calculation;

the date from which dividends on such offered preferred stock will accumulate, if applicable, and whether dividends will be cumulative;

the provisions for a retirement or sinking fund, if any;

the provisions for redemption, if applicable;

the voting rights, if any;

any listing of the preferred stock on any securities exchange or market;

whether the preferred stock will be convertible into our common stock and, if applicable, the conversion price, or how it will be calculated, and the conversion period;

preemptive rights, if any;

restrictions on transfer, sale or other assignment, if any;

a discussion of federal income tax considerations applicable to such offered preferred stock; and

any other specific terms, preferences, rights, limitations or restrictions of such offered preferred stock.

If the terms of any series of preferred stock being offered differ from the terms set forth in this prospectus, we will describe those terms in the prospectus supplement relating to that series of preferred stock. You should refer to the certificate of designations relating to the series of the preferred stock for the complete terms of that preferred stock. We will file that certificate of designations with the SEC promptly after the offering of the preferred stock.

The preferred stock will, when issued, be fully paid and nonassessable. Unless otherwise specified in the prospectus supplement, if we liquidate, dissolve or wind-up our business, each series of preferred stock will have the same rank as to dividends and distributions as each other series of the preferred stock we may issue in the future.

The issuance of preferred stock could adversely affect the rights of the holders of our common stock and therefore, reduce the value of the common stock. The ability of the board of directors to issue preferred stock could discourage, delay, or prevent a takeover of us.

Delaware Anti-Takeover Statute

We have elected not to be governed by Section 203 (“Section 203”) of the Delaware General Corporation Law (“DGCL”). In general, Section 203 prohibits a publicly held Delaware corporation from engaging in various “business combination” transactions with any interested stockholder for a period of three years following the time that such person became an interested stockholder, unless certain conditions are satisfied.

Provisions of Our Certificate of Incorporation, as Amended and Restated

Classified Board of Directors. Our certificate of incorporation provides that the members of our board of directors will be divided into three classes as nearly equal as possible, beginning at our 2015 annual meeting of stockholders. Initially, the three classes will be designated with one-, two- and three-year terms, after which directors in each class will be elected for three-year terms. As a result, the term for service on our board of directors expires for only a portion of our board of directors at each annual stockholder meeting, beginning at our 2016 annual stockholder meeting. The classification of our board of directors into separate classes with staggered terms may delay or prevent a change of our board of directors as a whole or our management or a change in control of our company.

Stockholder Action by Written Consent. Delaware law provides that, unless otherwise stated in a corporation’s certificate of incorporation, the stockholders may act by written consent without a meeting. Our certificate of incorporation provides that any action required or permitted to be taken by our stockholders at an annual meeting or special meeting of the stockholders may only be taken at an annual or special meeting before which it is properly brought, and not by written consent without a meeting.

Provisions of Our Bylaws, as Amended and Restated

Requirements for Advance Notification of Stockholder Nominations and Proposals. Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors.

Special Meetings. Our bylaws limit the ability to call special meetings of stockholders to the Board, the Chairman of the Board or the chief executive officer;

Quorum. Our bylaws reduce the quorum required for a stockholder meeting to one-third of the outstanding shares entitled to vote at the meeting.

Stockholder Vote Required to Amend Our Bylaws. Our bylaws require 50.1% of the issued and outstanding shares entitled to vote to amend the Bylaws.

Limitation of Liability and Indemnification

Our certificate of incorporation limits the liability of our directors for monetary damages for breach of their fiduciary duty as directors, except for liability that cannot be eliminated under the DGCL. Delaware law provides that directors of a company will not be personally liable for monetary damages for breach of their fiduciary duty as directors, except for liabilities:

for any breach of their duty of loyalty to us or our stockholders;

for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

for unlawful payment of dividend or unlawful stock repurchase or redemption, as provided under Section 174 of the DGCL; or

for any transaction from which the director derived an improper personal benefit.

Any amendment, repeal or modification of these provisions will be prospective only and would not affect any limitation on liability of a director for acts or omissions that occurred prior to any such amendment, repeal or modification.

Our certificate of incorporation and bylaws also provide that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. Our bylaws also permit us to purchase insurance on behalf of any officer, director, employee or other agent for any liability arising out of that person’s actions as our officer, director, employee or agent, regardless of whether Delaware law would permit indemnification. We have entered into an indemnification agreement with each of our directors and executive officers. The indemnification agreements provide the directors and executive officers with contractual rights to the indemnification and expense advancement rights provided under our bylaws, as well as contractual rights to additional indemnification as provided in the indemnification agreement.

Transfer Agent

The transfer agent and registrar for our common stock is VStock Transfer LLC whose address is 18 Lafayette Place, Woodmere, New York 11598.

DESCRIPTION OF DEPOSITARY SHARES

We may offer fractional interests in shares of preferred stock rather than full shares of preferred stock. In that event, depositary receipts will be issued to evidence depositary shares, each of which will represent a fraction of a share of a particular series of preferred stock, as described in the prospectus supplement relating to the particular issue of depositary shares.

The shares of preferred stock represented by depositary shares will be deposited under a deposit agreement between us and a depositary that is a bank or trust company, as depositary, that we select as set forth in the prospectus supplement relating to the particular issue of depositary shares. Unless otherwise specified in the prospectus supplement relating to a particular issue of depositary shares, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all the rights and preferences of the shares of preferred stock represented by such depositary share, including dividend and liquidation rights and any right to convert the shares of preferred stock into common stock.

We will describe the terms of any depositary shares we offer and the related depositary agreement, as well as the terms of the shares of preferred stock represented thereby, in the prospectus supplement relating to the particular issue of depositary shares. The forms of the depositary agreement and the depositary receipts relating to any particular issue of depositary shares will be filed with the SEC prior to our offering of the depositary shares, and you should read such documents for provisions that may be important to you.

DESCRIPTION OF WARRANTS

We may issue warrants entitling the holder to purchase our common stock, preferred stock or any combination thereof. Warrants may be issued independently or together with our common stock or preferred stock and may be attached to or separate from any such offered securities. The warrants will be issued under warrant agreements to be entered into between us and a bank, a trust company or our transfer agent, as warrant agent. The warrant agent will act solely as our agent in connection with warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants.

We will file the form of any warrant agreement with the SEC, and you should read the warrant agreement for provisions that may be important to you. The prospectus supplement will describe the terms of any warrants offered, including the following:

the title of the warrants;

the offering price for the warrants, if any;

the aggregate number of the warrants;

the designation and terms of the common stock or preferred stock that may be purchased upon exercise of the warrants;

if applicable, the date from and after which the warrants and any securities issued with the warrants will be separately transferable;

the number of shares of common stock or preferred stock that may be purchased upon exercise of a warrant and the exercise price for the warrants;

the dates on which the right to exercise the warrants shall commence and expire;

if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;

the anti-dilution provisions of the warrants, if any;

the redemption or call provisions, if any, applicable to the warrants;

any provisions with respect to holder’s right to require us to repurchase the warrants upon a change in control;

a discussion of certain U.S. federal income tax, accounting and other special considerations, procedures and limitations relating to the warrants; and

any other material terms of the warrants.

Holders of the equity warrants will not be entitled to:

vote, consent or receive dividends;

receive notice as stockholders with respect to any meeting of stockholders for the election of our directors or any other matter; or

exercise any rights as stockholders of the Company.

Warrants will be offered and exercisable for United States dollars only. Warrants will be issued in registered form only. Each warrant will entitle its holder to purchase such number of shares of common stock or preferred stock at such exercise price as is in each case set forth in, or calculable from, the prospectus supplement relating to the warrants. The exercise price may be subject to adjustment upon the occurrence of events described in such prospectus supplement. After the close of business on the date on which the right to exercise the warrants shall expire (or such later date to which we may extend such expiration date), unexercised warrants will become void. The place or places where, and the manner in which, warrants may be exercised will be specified in the prospectus supplement relating to such warrants.

PLAN OF DISTRIBUTION

We may sell the securities under this prospectus in one or more of the following ways (or in any combination) from time to time:

to or through one or more underwriters or dealers;

in short or long transactions;

directly to investors;

through agents; or

through a combination of these methods.

If underwriters or dealers are used in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including:

in privately negotiated transactions;

in one or more transactions at a fixed price or prices, which may be changed from time to time;

in “at-the-market offerings,” within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;

at prices related to those prevailing market prices; or

at negotiated prices.

As applicable, we and our underwriters, dealers or agents, reserve the right to accept or reject all or part of any proposed purchase of the securities. We will set forth in a prospectus supplement the terms and offering of securities by us, including:

the names of any underwriters, dealers or agents;

any agency fees or underwriting discounts or commissions and other items constituting agents’ or underwriters’ compensation;

any discounts or concessions allowed or reallowed or paid to dealers;

details regarding over-allotment options under which underwriters may purchase additional securities from us, if any;

the purchase price of the securities being offered and the proceeds we will receive from the sale;

the public offering price; and

the securities exchanges on which such securities may be listed, if any.

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions from time to time. If the applicable prospectus supplement indicates, in connection with those derivative transactions, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative transactions to close out any related open borrowings of securities. The third parties (or affiliates of such third parties) in such sale transactions by us will be underwriters and will be identified in an applicable prospectus supplement (or a post-effective amendment). We may also sell securities under this prospectus upon the exercise of rights that may be issued to our securityholders.

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus and an applicable prospectus supplement. Such financial institution or third party may transfer its economic short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus.

Underwriters, Agents and Dealers

If underwriters are used in the sale of our securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the securities if they purchase any of the securities. We may use underwriters with which we have a material relationship and will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

We may sell the securities through agents from time to time. When we sell securities through agents, the prospectus supplement will name any agent involved in the offer or sale of securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase our securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Underwriters, dealers and agents may contract for or otherwise be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments made by the underwriters, dealers or agents, under agreements between us and the underwriters, dealers and agents.

We may grant underwriters who participate in the distribution of our securities an option to purchase additional securities to cover over-allotments, if any, in connection with the distribution.

Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from us or our purchasers, as their agents in connection with the sale of our securities. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discounts and commissions. The prospectus supplement for any securities offered by us will identify any such underwriter, dealer or agent and describe any compensation received by them from us. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

Pursuant to a requirement by the Financial Industry Regulatory Authority (“FINRA”), the maximum commission or discount to be received by any FINRA member or independent broker/dealer must be considered fair and reasonable, as determined by FINRA based on specific factors set forth in the FINRA rules. If more than 5% of the net proceeds of any offering of securities made under this prospectus will be received by a FINRA member participating in the offering or its affiliates or associated persons of such FINRA member, the offering will be conducted in accordance with FINRA Conduct Rule 5110(h).

Any underwriter may engage in over-allotment transactions, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short-covering transactions involve purchases of our securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. We make no representation or prediction as to the direction or magnitude of any effect these transactions may have on the price of our securities. For a description of these activities, see the information under the heading “Underwriting” in the applicable prospectus supplement.

Underwriters, broker-dealers or agents who may become involved in the sale of our securities may engage in transactions with and perform other services for us for which they receive compensation.

Stabilization Activities

In connection with an offering through underwriters, an underwriter may, to the extent permitted by applicable rules and regulations, purchase and sell securities in the open market. These transactions, to the extent permitted by applicable rules and regulations, may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional securities from us in the offering, if any. If the underwriters have an over-allotment option to purchase additional securities from us, the underwriters may consider, among other things, the price of securities available for purchase in the open market as compared to the price at which they may purchase securities through the over-allotment option. “Naked” short sales, which may be prohibited or restricted by applicable rules and regulations, are any sales in excess of such option or where the underwriters do not have an over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.

Accordingly, to cover these short sales positions or to otherwise stabilize or maintain the price of the securities, the underwriters may bid for or purchase securities in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of the securities to the extent that it discourages resale of the securities. The magnitude or effect of any stabilization or other transactions is uncertain.

Direct Sales

We may also sell securities directly to one or more purchasers without using underwriters or agents. In this case, no agents, underwriters or dealers would be involved. We may sell securities upon the exercise of rights that we may issue to our securityholders. We may also sell securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities.

At-the-Market Offerings

To the extent that we make sales through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a sales agency financing agreement or other at-the-market offering arrangement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to any such agreement, we will issue and sell our securities through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell securities on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The agreement will provide that any securities sold will be sold at prices related to the then prevailing market prices for our securities. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time. Pursuant to the terms of the agreement, we may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common stock or other securities. The terms of each such agreement will be set forth in more detail in a prospectus supplement to this prospectus.

Subscription Offerings

We may also make direct sales through subscription rights distributed to our existing stockholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to our stockholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Item 15. Indemnification of Directors and Officers

Delaware General Corporation Law

Section 145 of the DGCL, pursuant to which the Company is incorporated, provides generally and in pertinent part that a Delaware corporation may indemnify its directors, officers, employees and agents (or persons serving at the request of the Company as a director, officer, employee or agent of another entity) against expenses, judgments, fines, and settlements actually and reasonably incurred by them in connection with any civil, criminal, administrative, or investigative suit or action except actions by or in the right of the corporation if, in connection with the matters in issue, they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and in connection with any criminal suit or proceeding, if in connection with the matters in issue, they had no reasonable cause to believe their conduct was unlawful. Section 145 further provides that in connection with the defense or settlement of any action by or in the right of the corporation, a Delaware corporation may indemnify its directors, officers, employees and agents (or persons serving at the request of the Company as a director, officer, employee or agent of another entity) against expenses actually and reasonably incurred by them if, in connection with the matters in issue, they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue, or matter as to which such person has been adjudged liable to the corporation unless the Delaware Court of Chancery or other court in which such action or suit is brought approves such indemnification. Section 145 further permits a Delaware corporation to grant its directors and officers additional rights of indemnification through bylaw provisions and otherwise, and or purchase indemnity insurance on behalf of its directors and officers.

Certificate of Incorporation and Bylaws

As permitted by the DGCL, in accordance with Section 102(b)(7) of the DGCL, our certificate of incorporation eliminates the personal liability of directors to us and to our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to us or our stockholders, (ii) for acts or omissions which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit. Our certificate of incorporation further provides that, if the DGCL is amended after the effective date of our certificate of incorporation to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Our certificate of incorporation and bylaws contains provisions that provide for indemnification of officers and directors to the full extent permitted by, and in the manner permissible under Delaware law. Delaware law empowers a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. A Delaware corporation may indemnify directors, officers, employees and other agents of such corporation in an action by or in the right of a corporation under the same conditions against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense and settlement of such action or suit, except that no indemnification is permitted without judicial approval if the person to be indemnified has been adjudged to be liable to the corporation.

II-1

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and executive officers, whereby we agree to indemnify the director or executive officer to the fullest extent permitted by law, if such individual was, is or becomes a party to, a witness to, or other participant in or threatened to be made a participant of a suit, proceeding, hearing or such whether civil, criminal, administrative, or investigative. The indemnification agreement shall not be deemed exclusive of any other rights to which such person may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall inure to the benefit of the heirs, executors and administrators of such person. The indemnification agreement also provides for, among other things, the advancement of expenses relating to the indemnification obligations, subject to reimbursement in the event the individual is not entitled to indemnification under applicable law and our certificate of incorporation.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to sections 13 or 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

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

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

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided , however , that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-3

(5) That, for the purpose of determining liability of a registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

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

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

II-4

GulfSlope Energy, Inc. 2500 City West, Suite 800 Houston, Texas 77042

Ladies and Gentlemen:

We have acted as counsel for GulfSlope Energy, Inc., a Delaware corporation (the "Company"), in connection with the preparation of a Registration Statement on Form S-3 (the "Registration Statement"), to be filed by the Company with the Securities and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended (the "Securities Act"). The Registration Statement relates to, among other things, the issuance and sale from time to time pursuant to Rule 415 of the General Rules and Regulations promulgated under the Securities Act, of the following securities:

(i) shares of common stock, par value $0.001 per share, including shares of common stock issuable upon conversion or exercise of other securities described herein to be offered and sold by the Company (the "Common Stock");

(ii) shares of preferred stock of the Company, par value $0.001 per share, including shares of preferred stock issuable upon conversion or exercise of other securities described herein (the "Preferred Stock");

(iii) depositary shares of the Company (“Depositary Shares”), each representing a fractional interest in a share of Preferred Stock, which may be issued pursuant to a deposit agreement (the “Deposit Agreement”) among the Company, a depositary to be named therein (the “Depositary”) and the holders from time to time of the Depositary Shares issued thereunder; and

(iv) warrants (the "Warrants") to purchase Common Stock or Preferred Stock.

The Common Stock, the Preferred Stock, the Depositary Shares and the Warrants are collectively referred to herein as the "Securities."

The Warrants may be issued pursuant to one or more warrant agreements (the terms and conditions of which will be set forth in one or more prospectus supplements relating to the issuance of Warrants) entered into between the Company and a financial institution identified therein as warrant agent, as such warrant agreements may be supplemented from time to time (each such warrant agreement, a "Warrant Agreement").

Mayer Brown LLP operates in combination with other Mayer Brown entities with offices in Europe and Asia

and is associated with Tauil & Chequer Advogados, a Brazilian law partnership.

In our capacity as counsel to the Company, we have examined the Registration Statement, the Amended and Restated Certificate of Incorporation of the Company and the Amended and Restated Bylaws of the Company. We have also examined originals, or duplicates or conformed copies, of such documents, corporate records, agreements and other instruments, and have made such other investigations, as we have deemed relevant and necessary for purposes of the opinions hereinafter set forth. As to questions of fact material to this opinion letter, we have relied upon certificates or comparable documents of public officials and upon oral or written statements and representations of officers and representatives of the Company.

During the course of such examination and review, and in connection with furnishing the opinions set forth below, we have assumed the accuracy and completeness of all documents and records that we have reviewed, the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of the documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as certified, conformed or reproduced copies. We are familiar with the proceedings taken and proposed to be taken by the Company in connection with the authorization and issuance of the Securities, and, for the purposes of this opinion letter, we have assumed that any future, similar or other required proceedings will be timely completed in the manner presently contemplated.

Based upon the foregoing, we are of the opinion that:

(1) With respect to any Common Stock, when necessary corporate action on the part of the Company has been taken to authorize a particular issuance and sale of Common Stock (including any issuance of Common Stock (i) upon the exchange or conversion of any validly issued, fully paid and non-assessable Preferred Stock that are exchangeable or convertible into Common Stock or (ii) upon the exercise of any validly issued Warrants to purchase Common Stock) and upon the issuance and delivery of and payment for such Common Stock in the manner contemplated by the Registration Statement (and in the case of the issuance of Common Stock pursuant to clauses (i) or (ii) above, upon the satisfaction of and compliance with the conditions to such exchange, conversion or exercise), such Common Stock will be validly issued, fully paid and non-assessable.

(2) With respect to any Preferred Stock, when necessary corporate action on the part of the Company has been taken to authorize a particular issuance and sale of Preferred Stock (including any issuance of shares of a series or class of Preferred Stock upon the exercise of any validly issued Warrants for the purchase of Preferred Stock) and upon the issuance and delivery of and payment for such Preferred Stock in the manner contemplated by the Registration Statement (and in the case of the issuance of Preferred Stock pursuant to the exercise of any Warrants, upon the satisfaction of and compliance with the conditions to the exercise), such Preferred Stock of such series or class will be validly issued, fully paid and non-assessable.
