CATCHER HOLDINGS, INC.

WARRANT TO PURCHASE [            ] SHARES OF

COMMON STOCK, PAR VALUE $0.001 PER SHARE

For VALUE RECEIVED, [                    ] (“Warrantholder”), is entitled to purchase, subject to the provisions of this Warrant, from Catcher Holdings, Inc., a Delaware corporation (the “Company”), at any time not later than 5:00 P.M., Eastern time, on the Expiration Date (as defined above), at an exercise price per share equal to $2.50 (the exercise price in effect being herein called the “Warrant Price”), [            ] shares (“Warrant Shares) of the Company’s Common Stock, par value $0.001 per share (“Common Stock”). The Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time as described herein.

Section 1. Registration. The Company shall maintain books for the transfer and registration of the Warrant. Upon the initial issuance of this Warrant, the Company shall issue and register the Warrant in the name of the Warrantholder.

Section 2. Transfers. As provided herein, this Warrant may be transferred only pursuant to a registration statement filed under the Securities Act of 1933, as amended (the “Securities Act”), or an exemption from such registration. Subject to such restrictions, the Company shall transfer this Warrant from time to time upon the books to be maintained by the Company for that purpose, upon surrender thereof for transfer properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including, if required by the Company, an opinion of the Warrantholder’s counsel to the effect that such transfer is exempt from the registration requirements of the Securities Act, to establish that such transfer is being made in accordance with the terms hereof, and a new Warrant shall be issued to the transferee and the surrendered Warrant shall be canceled by the Company.

Section 3. Exercise of Warrant. Subject to the provisions hereof, the Warrantholder may exercise the Warrant in whole or in part at any time prior to its expiration upon surrender of the Warrant, together with delivery of the duly executed Warrant exercise form attached hereto as Appendix A (the “Exercise Agreement”) and payment by cash, certified check or wire transfer of funds for the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal business hours on any business day at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the Warrantholder). The Warrant Shares so purchased shall be deemed to be issued to the Warrantholder or the Warrantholder’s designees, as the record owner of such shares, as of the

close of business on the date on which this Warrant shall have been surrendered (or evidence of loss, theft or destruction thereof and security or indemnity satisfactory to the Company), the Warrant Price shall have been paid and the completed Exercise Agreement shall have been delivered. Certificates for the Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall be delivered to the Warrantholder within reasonable time, not exceeding five (5) business days, after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the Warrantholder and shall be registered in the name of the Warrantholder or such other name as shall be designated by the Warrantholder. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the Warrantholder a new Warrant representing the number of shares with respect to which the Warrant shall not then have been exercised. As used herein, “business day” means a day, other than a Saturday or Sunday, on which banks in New York City are open for the general transaction of business.

Section 4. Warrantholder Representations and Warranties.

(a) The Warrantholder represents that the Warrantholder is an “accredited investor” as such term is defined in Rule 501 of Regulation D (“Regulation D”) promulgated under the Securities Act and that the Warrantholder is able to bear the economic risk of an investment in the Warrants and the Common Stock.

(b) The Warrantholder understands that the Warrants have not been registered under the Securities Act by reason of a claimed exemption under the provisions of the Securities Act that depends, in part, upon the Warrantholder’s investment intention. In this connection, the Warrantholder hereby represents that the Warrantholder is purchasing the Warrants for the Warrantholder’s own account for investment and not with a view toward the resale or distribution to others. The Warrantholder, if an entity, further represents that it was not formed for the purpose of purchasing the Warrants and the Common Stock.

(c) The Warrantholder consents to the placement of a legend on any certificate or other document evidencing the securities that such securities have not been registered under the Securities Act or any state securities or “blue sky” laws and setting forth or referring to the restrictions on transferability and sale thereof contained in this Agreement. The Warrantholder is aware that the Company will make a notation in its appropriate records with respect to the restrictions on the transferability of such securities. The legend to be placed on each certificate shall be in form substantially similar to the legend set forth on the first page of this Warrant.

Section 5. Payment of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the Warrantholder in respect of which such shares are issued, and in such case, the Company shall not be required to issue or deliver any certificate for Warrant Shares or any Warrant until the person requesting the same has paid to the Company the amount of such tax or has established to the Company’s reasonable satisfaction that such tax has been paid. The Warrantholder shall be responsible for income taxes due under federal, state or other law, if any such tax is due.

Section 6. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and upon cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or

2

destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with respect thereto, if requested by the Company.

Section 7. Reservation of Common Stock. The Company hereby covenants that there will be reserved, and the Company shall at all applicable times thereafter keep reserved until issued (if necessary) as contemplated by this Section 7, out of the authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of purchase represented by this Warrant. The Company agrees that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company.

Section 8. Adjustments. Subject and pursuant to the provisions of this Section 8, unless waived in a particular case by the Warrantholder, the Warrant Price and number of Warrant Shares subject to this Warrant shall be subject to adjustment from time to time as set forth hereinafter.

(a) If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the Company is continuing the corporation), then the number of Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in effect immediately prior to the date upon which such change shall become effective, shall be adjusted by the Company so that the Warrantholder thereafter exercising the Warrant shall be entitled to receive the number of shares of Common Stock or other capital stock which the Warrantholder would have received if the Warrant had been exercised immediately prior to such event upon payment of the Warrant Price. Such adjustments shall be made successively whenever any event listed above shall occur.

(b) If the Company shall, at any time or from time to time while this Warrant is outstanding, reclassify its capital stock, consolidate or merge with or into another corporation (where the Company is not the surviving corporation or where there is a change in or distribution with respect to the Common Stock), or sell, transfer or otherwise dispose of its property, assets or business to another corporation and, pursuant to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in lieu of common stock of the successor or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Stock of the Company, then, from and after the consummation of such transaction or event, the Warrantholder shall have the right thereafter to receive, instead of the Warrant Shares, at the sole option of the Warrantholder, upon exercise of this Warrant, the number of shares of common stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and Other Property receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets by a Warrantholder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event. The foregoing provisions of this Section 8(b) shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or disposition of assets.

3

(c) Anything herein to the contrary notwithstanding, the Company shall not be required to make any adjustment to the Warrant Price in the case of the issuance of (A) capital stock, options or convertible securities issued to directors, officers, employees or consultants of the Company in connection with their service as directors of the Company, their employment by the Company or their retention as consultants by the Company pursuant to an equity compensation program approved by the Board of Directors of the Company or the compensation committee of the Board of Directors of the Company, (B) shares of the Common Stock issued upon the conversion or exercise of options or convertible securities issued prior to the date hereof, (C) shares of Common Stock issued or issuable by reason of a dividend, stock split or other distribution on shares of Common Stock (but only to the extent that such a dividend, split or distribution results in an adjustment in the Warrant Price pursuant to the other provisions of this Warrant).

Section 9. Fractional Interest. The Company shall not be required to issue fractions of Warrant Shares upon the exercise of this Warrant. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 9, be deliverable upon such exercise, the Company, in lieu of delivering such fractional share, shall pay to the exercising Warrantholder an amount in cash equal to the Market Price of such fractional share of Common Stock on the date of exercise.

Section 10. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder.

Section 11. Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price or number of Warrant Shares subject to this Warrant, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company, stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment.

Section 12. Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery, (ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, (iii) if given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one business day after delivery to such carrier and (v) if given by electronic mail with no notice of delivery failure, then such notice shall be deemed given upon the date of delivery.
