GEOSPATIAL HOLDINGS, INC.

WARRANT TO PURCHASE COMMON STOCK

Void After March 2, 2012

THIS WARRANT (the “Warrant”) CERTIFIES THAT, for value received, Ridge Global LLC, a limited liability company duly organized under the laws of the State of Delaware (the “Holder”), or any authorized successor or assign, is entitled, on and subject to the terms set forth below, to purchase from Geospatial Holdings, Inc., a Nevada corporation (the “Company”), two million four hundred thousand (2,400,000) shares (the “Share Number”) of Common Stock (as defined below) of the Company. The Share Number shall also be subject to adjustment as set forth below in Section 5.

1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings:

(a) “Common Stock” shall mean shares of the Company’s common stock each having a par value of $0.001.

(b) “Exercise Period” shall mean the period commencing with the Issuance Date, and ending March 2, 2012, unless sooner terminated as provided below.

(c) “Exercise Price” shall mean one dollar ($1.00) per share of Common Stock.

(d) “Exercise Shares” shall mean the shares of Common Stock issuable upon exercise of this Warrant.

2. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth below (or at such other address as it may designate by notice in writing to the Holder):

(a) an executed Notice of Exercise in the form attached hereto;

1.

(b) payment of the Exercise Price in cash by wire transfer of immediately available funds; and

(c) this Warrant.

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased, registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

2.1. Net Exercise. Notwithstanding any provisions herein to the contrary, if the fair market value of one share of the Company’s Common Stock is greater than the Exercise Price (at the date of exercise), in lieu of exercising this Warrant by payment of cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y (A-B)

            A

For purposes of the above calculation, fair market value means on any date, as it relates to a share of the Company’s Common Stock (each a “Share”): (i) if the Shares are readily tradable on an established securities market, (x) the average of the high and low prices of such Shares as reported on the principal national securities exchange on which the Shares are then listed on the date specified herein, or if there were no sales on such date, on the next preceding day on which there were sales, or (y) if such Shares are not listed on a national securities exchange, the average

2.

of the last reported bid price, as reported by Financial Industry Regulatory Authority, Inc. or a similar organization, in the over-the-counter market for such Shares for each of the twenty (20) business days preceding the specified date, or (ii) if the Shares are not readily tradable on an established securities market, the value determined by any means determined fair and reasonable by the board of directors of the Company, which determination shall be final and binding on all parties.

3. COVENANTS OF THE COMPANY.

3.1. Covenants as to Exercise Shares. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

3.2. No Impairment. Except and to the extent as waived or consented to by the Holder, the Company will not, by amendment of its organizational documents or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment.

3.3. Notices of Record Date. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend which is the same as cash dividends paid in previous quarters) or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution.

4. REPRESENTATIONS OF HOLDER.

4.1. Acquisition of Warrant for Personal Account. The Holder represents and warrants that it is acquiring the Warrant solely for its account for investment and not with a view to or for sale or distribution of said Warrant or any part thereof. The Holder also represents that the entire legal and beneficial interests of the Warrant and Exercise Shares the Holder is acquiring is being acquired for, and will be held for, its account only.

3.

4.2. Securities Are Not Registered.

(a) The Holder understands that the Warrant and the Exercise Shares have not been registered under the Securities Act of 1933, as amended (the “Act”) on the basis that no distribution or public offering of the stock of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention.

(b) The Holder recognizes that the Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available. The Holder recognizes that the Company has no obligation to register the Warrant or the Exercise Shares of the Company, or to comply with any exemption from such registration.

(c) The Holder is aware that neither the Warrant nor the Exercise Shares may be sold pursuant to Rule 144 adopted under the Act unless certain conditions are met, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale following the required holding period under Rule 144 and the number of shares being sold during any three month period not exceeding specified limitations. Holder is aware that the conditions for resale set forth in Rule 144 have not been satisfied and that the Company presently has no plans to satisfy these conditions in the foreseeable future.

4.3. Disposition of Warrant and Exercise Shares.

(a) The Holder further agrees not to make any disposition of all or any part of the Warrant or Exercise Shares in any event unless and until:

(i) the Company shall have received a letter secured by the Holder from the Securities and Exchange Commission stating that no action will be recommended to the Commission with respect to the proposed disposition; or

(ii) there is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with said registration statement; or

(iii) the Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the effect that such disposition will not require registration of such Warrant or Exercise Shares under the Act or any applicable state securities laws.

4.

(b) The Holder understands and agrees that all certificates evidencing the shares to be issued to the Holder may bear the following legend:

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”). THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

(c) The Holder hereby agrees not to sell or otherwise transfer or dispose of all or any part of this Warrant or the Exercise Shares during a period specified by the representative of the underwriters of Common Stock (not to exceed one hundred eighty (180) days) following the effective date of any registration statement of the Company filed under the Act. Holder further agrees that the Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period.

4.4. Accredited Investor. The Holder represents that it is an accredited investor within the meaning of Regulation D of the Securities Act.

5. ADJUSTMENT OF EXERCISE PRICE. In the event of changes in the outstanding Common Stock of the Company by reason of stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had the Warrant been exercised prior to the event and had the Holder continued to hold such shares until after the event requiring adjustment; provided, however, that such adjustment shall not be made with respect to, and this Warrant shall terminate if not exercised prior to the end of the Exercise Period. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant.

6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the Exercise Price by such fraction.

7. NO STOCKHOLDER RIGHTS. This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.

8. TRANSFER OF WARRANT. Subject to applicable laws and the restriction on transfer set forth on the first page of this Warrant, this Warrant and all rights hereunder are

5.

transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. The transferee shall sign an investment letter in form and substance satisfactory to the Company.

9. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

10. NOTICES, ETC. All notices and other communications required or permitted hereunder shall be in writing and shall be sent by telex, telegram, express mail or other form of rapid communications, if possible, and if not then such notice or communication shall be mailed by first-class mail, postage prepaid, addressed in each case to the party entitled thereto at the following addresses:
