WARRANT AGREEMENT

To Purchase Shares of the Common Stock of

Planet Payment, Inc.

Dated as of            (the “Issue Date”)

WHEREAS, Planet Payment, Inc. a Delaware corporation (the “Company”) has agreed to grant to the person named on the signature page hereto (the “Warrantholder”), the right to purchase shares of its Common Stock;

NOW, THEREFORE, for good and valuable consideration, receipt whereof the Company hereby acknowledges and in consideration of mutual covenants and agreements contained herein, the Company and Warrantholder agree as follows:

1.             GRANT OF THE RIGHT TO PURCHASE COMMON STOCK.

The Company hereby grants to the Warrantholder, and the Warrantholder is entitled, upon the terms and subject to the conditions hereinafter set forth, to subscribe to and purchase, from the Company, such number of fully paid and non-assessable shares of the Company’s Common Stock of $0.01 par value each (“Common Stock”) as is set forth on the signature page hereto, at a purchase price of $           per share (the “Exercise Price”). The number and purchase price of such shares are subject to adjustment as provided in Section 8 hereof.

2.             TERM OF THE WARRANT AGREEMENT.

Except as otherwise provided for herein, the term of this Warrant Agreement and the right to purchase Common Stock as granted herein shall commence on the Issue Date (the “Exercise Commencement Date”) and shall be exercisable until 5:00 p.m. New York time on            (the “Expiration Date”).

3.             EXERCISE OF THE PURCHASE RIGHTS.

(a)           Exercise.  The purchase rights set forth in this Warrant Agreement are exercisable by the Warrantholder, in whole or in part, at any time, or from time to time, prior to the expiration of the term set forth in Section 2 above, by tendering to the Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly completed and executed. Promptly upon receipt of the Notice of Exercise and the payment of the purchase price in accordance with the terms set forth below, and in no event later than twenty-one (21) days thereafter, the Company shall issue to the Warrantholder a certificate for the number of shares of Common Stock purchased and shall execute the acknowledgment of exercise in the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain subject to future purchases, if any.

The Exercise Price may be paid at the Warrantholder’s election either (i) by cash or check, or (ii) by surrender of Warrants (“Net Issuance”) as determined below. If the Warrantholder elects the Net Issuance method, the Company will issue Common Stock in accordance with the following formula:

Where:   X =          the number of shares of Common Stock to be issued to the Warrantholder.

Y =          the number of shares of Common Stock requested to be exercised under this Warrant Agreement.

1

A =         the fair market value of one (1) share of Common Stock on the date of exercise.

B =          the Exercise Price.

For purposes of the above calculation, current fair market value of Common Stock shall mean with respect to each share of Common Stock:

(i)            if the exercise is in connection with an initial public offering of the Company’s Common Stock, and if the Company’s Registration Statement relating to such public offering has been declared effective by the SEC, then the fair market value per share shall be the initial “Price to Public” specified in the final prospectus with respect to the offering;

(ii)           if this Warrant is exercised after, and not in connection with the Company’s initial public offering, and:

(a)           if traded on a securities exchange including the AIM market of the London Stock Exchange Plc (“AIM”), the fair market value shall be deemed to be the average of the closing prices over a five (5) day period ending three days before the day the current fair market value of the securities is being determined; or

(b)           if actively traded over-the-counter, the fair market value shall be deemed to be the average of the closing bid and asked prices quoted on the OTCQX or NASDAQ system (or similar system) over the five (5) day period ending three days before the day the current fair market value of the securities is being determined;

(iii)         if at any time the Common Stock is not listed on any securities exchange or quoted in the OTCQX or NASDAQ System or the over-the-counter market, the current fair market value of Common Stock shall be the highest price per share which the Company could obtain from a willing buyer (not a current employee or director) for shares of Common Stock sold by the Company, from authorized but unissued shares, as determined in good faith by its Board of Directors, unless the Company shall become subject to a merger, acquisition or other consolidation pursuant to which the Company is not the surviving party, in which case the fair market value of Common Stock shall be deemed to be the value received by the holders of the Company’s Common Stock pursuant to such merger or acquisition.

Upon partial exercise by either cash or Net Issuance, the Company shall promptly issue an amended Warrant Agreement representing the remaining number of shares purchasable hereunder. All other terms and conditions of such amended Warrant Agreement shall be identical to those contained herein, including, but not limited to the Effective Date hereof.

(b)           Exercise Prior to Expiration. To the extent this Warrant is not previously exercised as to all Common Stock subject hereto, and if the fair market value of one share of the Common Stock is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised pursuant to Section 3(a) above (even if not surrendered) immediately before its expiration. For purposes of such automatic exercise, the fair market value of one share of the Common Stock upon such expiration shall be determined pursuant to Section 3(a) above. To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to promptly notify the Warrantholder of the number of Common Stock, if any, the Warrantholder is to receive by reason of such automatic exercise.

4.             RESERVATION OF SHARES.

During the term of this Warrant Agreement, the Company will at all times have authorized and reserved a sufficient number of shares of its Common Stock to provide for the exercise of the rights to purchase Common Stock as provided for herein. The company agrees that the issuance of this Warrant constitutes full authority of its officers who are charged with issuance of stock certificates to issue the necessary certificates for shares of Common Stock as the case may be, upon exercise of this Warrant.

5.             NO FRACTIONAL SHARES OR SCRIP.

No fractional shares or scrip representing fractional shares shall be issued upon the exercise of the Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Exercise Price then in effect.

2

6.             NO RIGHTS AS SHAREHOLDER.

This Warrant Agreement does not entitle the Warrantholder to any voting rights or other rights as a shareholder of the Company prior to the exercise of the Warrant. Warrantholder shall be deemed for all purposes to be a shareholder as of the date of proper exercise (including payment of the applicable exercise price) of this Warrant as to the shares acquired upon such exercise.

7.             WARRANTHOLDER REGISTRY.

The Company shall maintain a registry showing the name and address of the registered holder of this Warrant Agreement.

8.             ADJUSTMENT RIGHTS.

The purchase price per share and the number of shares of Common Stock purchasable hereunder are subject to adjustment, as follows:

(a)           Merger and Sale of Assets.  If at any time there shall be a capital reorganization of the shares of the Company’s stock (other than a combination, reclassification, exchange or subdivision of shares otherwise provided for herein), or a merger or consolidation of the Company with or into another corporation whether or not the Company is the surviving corporation, or the sale of all or substantially all of the Company’s properties and assets to any other person (hereinafter referred to as a “Merger Event”), then, as a part of such Merger Event, lawful provision shall be made so that the Warrantholder shall thereafter be entitled to receive, upon exercise of the Warrant, the number of shares of stock or other securities of the successor corporation resulting from such Merger Event, equivalent in value to that which would have been issuable if Warrantholder had exercised this Warrant immediately prior to the Merger Event. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board of Directors) shall be made in the application of the provisions of this Warrant Agreement with respect to the rights and interest of the Warrantholder after the Merger Event to the end that the provisions of this Warrant Agreement (including adjustments of the Exercise Price and number of shares of Common Stock purchasable) shall be applicable to the greatest extent possible.

(b)           Reclassification of Shares.  If the Company at any time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities as to which purchase rights under this Warrant Agreement exist into the same or a different number of securities of any other class or classes, this Warrant Agreement shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this Warrant Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change.

(c)           Subdivision or Combination of Shares.  If the Company at any time shall combine or subdivide its Common Stock, the Exercise Price shall be proportionately decreased in the case of a subdivision, or proportionately increased in the case of a combination.

(d)           Stock Dividends.  If the Company at any time shall pay a dividend payable in, or make any other distribution (except any distribution specifically provided for in the foregoing subsections (a) or (b)) of the Company’s stock, then the Exercise Price shall be adjusted, from and after the record date of such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction (i) the numerator of which shall be the total number of all shares of the Company’s stock outstanding immediately prior to such dividend or distribution, and (ii) the denominator of which shall be the total number of all shares of the Company’s stock outstanding immediately after such dividend or distribution. The Warrantholder shall thereafter be entitled to purchase, at the Exercise Price resulting from such adjustment, the number of shares of Common Stock (calculated to the nearest whole share) obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon the exercise hereof immediately prior to such a adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment.

(e)           Officer’s Certificate.  Whenever the Exercise Price or the shares issuable upon exercise of this Warrant shall be adjusted as required by the provisions of this Section, the Company shall promptly file with its Secretary and its stock transfer agent, if any, an officer’s certificate showing the adjusted Exercise Price and Warrant shares determined as provided in this Section and showing in reasonable detail the facts requiring such adjustment. Each such officer’s certificate shall be promptly delivered to Warrantholder after each such adjustment.

3

(f)            Notice of Adjustments.  If: (i) the Company shall declare any dividend or distribution payable in its stock; (ii) there shall be any Merger Event; (iii) there shall be an initial public offering; or (iv) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall send to the Warrantholder: (A) at least twenty (20) days’ prior written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution, or for determining rights to vote in respect of such Merger Event, dissolution, liquidation or winding up; (B) in the case of any such Merger Event, dissolution, liquidation or winding up, at least twenty (20) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding up); and (C) in the case of a public offering, the Company shall give the Warrantholder at least twenty (20) days written notice prior to the effective date thereof.

Each such written notice shall set forth, in reasonable detail, (i) the event requiring the adjustment, (ii) the amount of the adjustment, (iii) the method by which such adjustment was calculated, (iv) the Exercise Price, and (v) the number of shares subject to purchase hereunder after giving effect to such adjustment, and shall be given by first class mail, postage prepaid, addressed to the Warrantholder, at the address as shown on the books of the Company.

(g)           Timely Notice.  Failure to timely provide such notice required by subsection (f) above shall entitle Warrantholder to retain the benefit of the applicable notice period notwithstanding anything to the contrary contained in any insufficient notice received by Warrantholder. The notice period shall begin on the date Warrantholder actually receives a written notice containing all the information specified above.

9.             REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

(a)           Reservation of Common Stock.  The Common Stock issuable upon exercise of the Warrantholder’s rights has been duly and validly reserved and, when issued in accordance with the provisions of this Warrant Agreement, will be validly issued, fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; provided, however, that the Common Stock issuable pursuant to this Warrant Agreement may be subject to restrictions on transfer under state and/or Federal securities laws. The Company has made available to the Warrantholder true, correct and complete copies of its Charter and Bylaws, as amended. The issuance of certificates for shares of Common Stock upon exercise of the Warrant Agreement shall be made without charge to the Warrantholder for any issuance tax in respect thereof, or other cost incurred by the Company in connection with such exercise and the related issuance of shares of Common Stock. The Company shall not be required to pay any tax, which may be payable in respect of any transfer involved and the issuance and delivery of any certificate in a name other than that of the Warrantholder.

(b)           Due Authority.  The execution and delivery by the Company of this Warrant Agreement and the performance of all obligations of the Company hereunder, including the issuance to Warrantholder of the right to acquire the shares of Common Stock, have been duly authorized by all necessary corporate action on the part of the Company, and this Warrant Agreement is not inconsistent with the Company’s Charter or Bylaws, does not contravene any law or governmental rule, regulation or order applicable to it, do not and will not contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument to which it is a party or by which it is bound, and this Warrant Agreement constitutes the legal, valid and binding agreement of the Company, enforceable in accordance with its terms.

10.          REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

This Warrant Agreement has been entered into by the Company in reliance upon the following representations and covenants of the Warrantholder:

(a)           Investment Purpose.  The right to acquire Common Stock or the Common Stock issuable upon exercise of the Warrantholder’s rights contained herein will be acquired for investment and not with a view to the sale or distribution of any part thereof, and the Warrantholder has no present intention of selling or engaging in any public distribution of the same except pursuant to a registration or exemption.

4

(b)           Private Issue.  The Warrantholder understands (i) that the Common Stock issuable upon exercise of this Warrant is not registered under the 1933 Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this Warrant Agreement will be exempt from the registration and qualifications requirements thereof, and (ii) that the Company’s reliance on such exemption is predicated on the representations set forth in this Section 10.

(c)           Disposition of Warrantholder’s Rights.  In no event will the Warrantholder make a disposition of any of its rights to acquire Common Stock or Common Stock issuable upon exercise of such rights unless and until (i) it shall have notified the Company of the proposed disposition, and (ii) if requested by the Company, it shall have furnished the Company with an opinion of counsel (which counsel may either be inside or outside counsel to the Warrantholder) satisfactory to the Company and its counsel to the effect that (A) appropriate action necessary for compliance with the 1933 Act has been taken, or (B) an exemption from the registration requirements of the 1933 Act is available. Notwithstanding the foregoing, the restrictions imposed upon the transferability of any of its rights to acquire Common Stock or Common Stock issuable on the exercise of such rights do not apply to transfers from the beneficial owner of any of the aforementioned securities to its nominee or from such nominee to its beneficial owner nor from the Warrantholder to its general partners and shall terminate as to any particular share of Common Stock when (1) such security shall have been effectively registered under the 1933 Act and sold by the holder thereof in accordance with such registration or (2) such security shall have been sold without registration in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been issued to the Warrantholder at its request by the staff of the Securities and Exchange Commission or a ruling shall have been issued to the Warrantholder at its request by such Commission stating that no action shall be recommended by such staff or taken by such Commission, as the case may be, if such security is transferred without registration under the 1933 Act in accordance with the conditions set forth in such letter or ruling and such letter or ruling specifies that no subsequent restrictions on transfer are required. Whenever the restrictions imposed hereunder shall terminate, as hereinabove provided, the Warrantholder or holder of a share of Common Stock then outstanding as to which such restrictions have terminated shall be entitled to receive from the Company, without expense to such holder, one or more new certificates for the Warrant or for such shares of Common Stock not bearing any restrictive legend.

(d)           Financial Risk.  The Warrantholder has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment, and has the ability to bear the economic risks of its investment.

(e)           Risk of No Registration.  The Warrantholder understands that if the Company does not register with the Securities and Exchange Commission pursuant to Section 12 of the 1934 Act (the “1934 Act”), or file reports pursuant to Section 15(d), of the 1934 Act, or if a registration statement covering the securities under the 1933 Act is not in effect when it desires to sell (i) the rights to purchase Common Stock pursuant to this Warrant Agreement, or (ii) the Common Stock issuable upon exercise of the right to purchase, it may be required to hold such securities for an indefinite period. The Warrantholder also understands that any sale of its rights of the Warrantholder to purchase Common Stock or Common Stock, which might be made by it in reliance upon Rule 144 under the 1933 Act, may be made only in accordance with the terms and conditions of that Rule.

(f)            Accredited Investor.  Warrantholder is an “accredited investor” within the meaning of the Securities and Exchange Rule 501 of Regulation D promulgated under the 1933 Act, as presently in effect
