COMMON STOCK PURCHASE WARRANT

OMTOOL, LTD.

1.             Issuance.  This Warrant is issued to Broadband Capital Management LLC by Omtool, Ltd., a Delaware corporation (hereinafter with its successors called the “Company”).

2.             Purchase Price; Number of Shares.  Subject to the terms and conditions hereinafter set forth, the registered holder of this Warrant (the “Holder”) is entitled upon surrender of this Warrant with the subscription form annexed hereto duly executed, at the office of the Company, 8A Industrial Way, Salem, New Hampshire 03079, or such other office as the Company shall notify the Holder of in writing, to purchase from the Company, at a price per share equal to Twelve Dollars ($12.00) (the “Purchase Price”), Twenty-five Thousand Five Hundred (25,500) fully paid and nonassessable shares (the “Warrant Shares”) of Common Stock, $0.01 par value per share, of the Company (the “Common Stock”).  Until such time as this Warrant is exercised in full, expires or otherwise terminates, the Purchase Price and the Common Stock issuable upon exercise of this Warrant are subject to adjustment as hereinafter provided.

3.             Exercise Date.  Except as otherwise provided in this Section 3 or Section 10, this Warrant may only be exercised during the period commencing on October 1, 2004 (the “Exercise Date”) and ending on the Expiration Date (as defined in Section 7).

4.             Payment of Purchase Price.  (a) The Purchase Price may be paid by check or by wire transfer of immediately available funds.

(b)           Net Issue Election.  The holder hereof may elect to receive, without the payment by such holder of any additional consideration, shares equal to the value of this Warrant or any portion hereof by the surrender of this Warrant or such portion to the Company, with the form of subscription at the end hereof duly executed by such holder, at the office of the Company.  Thereupon, the Company shall issue to such holder such number of fully paid and nonassessable shares of Common Stock as is computed using the following formula:

X = Y (A-B)

  A

where     X =          the number of shares to be issued to such holder pursuant to this subsection 1.4.

Y =          the number of shares covered by this Warrant in respect of which the net issue election is made pursuant to this subsection 1.4.

A =         the fair market value (“FMV”) of one share of Common Stock, as determined in accordance with the provisions of this Section 4(b), as at the time the net issue election is made pursuant to this subsection 1.4.

B =          the Purchase Price in effect under this Warrant at the time the net issue election is made pursuant to this subsection 1.4.

For the purposes of this Section 4(b), FMV shall be determined at the time of exercise and shall mean:  (A) if the Common Stock is then publicly traded, the average of the last sale price per share as reported by the Nasdaq National Market or the Nasdaq SmallCap Market (or on any other national securities exchange on which the Common Stock is traded) (or if the last reported sale price is not available for any such days, the average of the mean of the closing bid and ask prices for such days) for the ten (10) prior trading days or (B) if the Common Stock is not then publicly traded, the fair market value of one share of Common Stock shall be determined in good faith by the Board of Directors of the Company.  In the event the Common Stock is not publicly traded, the Board of Directors of the Company shall promptly respond in writing to an inquiry by the holder hereof as to the fair market value of one share of Common Stock for purpose of this Section 4(b).

5.             Partial Exercise.  This Warrant may be exercised in part, in which event the Holder shall be entitled to receive a new warrant, which shall have the same terms and shall be dated as of the date of this Warrant, covering the number of Warrant Shares in respect of which this Warrant shall not have been exercised.

6.             Issuance Date.  The person or persons in whose name or names any certificate representing shares of Common Stock is issued hereunder shall be deemed to have become the holder of record of the shares represented thereby as at the close of business on the date this Warrant is exercised with respect to such shares, whether or not the transfer books of the Company shall be closed.

7.             Expiration Date.  Unless earlier terminated as provided in Section 10, this Warrant shall expire on the close of business on September 30, 2009 (the “Expiration Date”), and shall be void thereafter.

8.             Reserved Shares; Valid Issuance.  The Company covenants that it will at all times from and after the date hereof reserve and keep available such number of its authorized shares of Common Stock, free from all preemptive or similar rights therein, as will be sufficient to permit the exercise of this Warrant in full.  The Company further covenants that such shares as may be issued pursuant to the exercise of this Warrant will, upon issuance, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof.

9.             Adjustment.  Each of the Purchase Price and the number of shares issuable on the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of the following events, after the Original Issue Date.

(a)           Stock Splits, Stock Dividends, Combinations.  In the event that the Company shall after the Original Issue Date (i) issue additional shares of the Common Stock as a dividend or other distribution on outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock, or (iii) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the Purchase Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Purchase Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Purchase Price then in effect.  The Purchase Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this subsection 9(a).  The holder of this Warrant shall thereafter, on the exercise hereof, be entitled to receive that number of shares of Common Stock determined by multiplying the number of shares of Common Stock which would otherwise (but for the provisions of this section 9(a)) be issuable on such exercise by a fraction of which (i) the numerator is the Purchase Price which would otherwise (but for the provisions of this section 9(a)) be in effect, and (ii) the denominator is the Purchase Price in effect on the date of such exercise.

(b)           No Voting or Dividend Rights.  Nothing contained in this Warrant shall be construed as conferring upon the Holder hereof the right to vote or to consent or to receive notice as a stockholder in respect of meetings of stockholders for the election of directors of the Company, to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger or conveyance) or any other matters or any rights whatsoever as a stockholder of the Company.  No dividends or interest shall be payable or accrued in respect of this Warrant or the interest represented hereby or, until and only to the extent that this Warrant shall have been exercised, the shares purchasable hereunder.

11.           Fractional Shares.  In no event shall any fractional share of Common Stock be issued upon any exercise of this Warrant.  If, upon exercise of this Warrant as an entirety, the Holder would, except as provided in this Section 11, be entitled to receive a fractional share of Common Stock, then, in lieu thereof, the Company shall pay cash to the Holder equal to such fraction multiplied by the closing price per share of the Common Stock on the Nasdaq National Market or the Nasdaq SmallCap Market, as applicable on the trading day period preceding the date of such exercise (or, if the Common Stock is not then so quoted, by the fair market value of one share of Common Stock as determined by the Company).

14.           Representations and Covenants of the Holder.

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

(a)           Investment Purpose.  This Warrant and the shares of Common Stock issuable upon exercise of this Warrant are being and will be acquired for investment and not with a view to or in connection with any distribution thereof, and the Holder has no present intention of selling or engaging in any public distribution of the same except in accordance with the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”) or pursuant to an exemption from such registration requirements.

(b)           Private Issue.  The Holder understands (i) that the shares of Common Stock issuable upon exercise of this Warrant are not registered under the Securities Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this Warrant 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 14.

(c)           Disposition of Holder’s Rights.  In no event will the Holder make a disposition of any of the shares of Common Stock issuable upon exercise of this Warrant except (i) pursuant to a registration under the Securities Act, or (ii) in compliance with Rule 144 under, or in compliance with another exemption from the registration requirements of, the Securities Act.  In connection with any disposition of any shares in compliance with Rule 144 or any other exemption from the registration requirements of the Securities Act, the Holder shall furnish the

Company with representation letters and an opinion of counsel, each reasonably satisfactory in form and substance to the Company and its counsel, to the effect that such exemption from the registration requirements of the Securities Act is available.  Notwithstanding the foregoing, the restrictions imposed upon the transferability of any the shares of Common Stock issuable upon the exercise of this Warrant 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, and shall terminate as to any particular share of Common Stock when (1) such securities shall have been effectively registered under the Securities Act and sold by the holder thereof in accordance with such registration or (2) such securities shall have been sold without registration in compliance with Rule  144 under, or another exemption from the registration requirements of, the Securities Act.  Whenever the restrictions imposed hereunder shall terminate, as hereinabove provided, the holder of a share of Common Stock then outstanding as to which such restrictions have terminated shall be entitled to receive from the Company one or more new certificates for such shares of Common Stock not bearing any restrictive legend.

(d)           Financial Risk.  The Holder 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 Holder understands that if the Company does not register with the Securities and Exchange Commission (the “Commission”) pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or file reports pursuant to Section 15(d) of the Exchange Act, or if a registration statement covering the Common Stock issuable upon the exercise of this Warrant under the Securities Act is not in effect when it desires to sell the Common Stock issuable upon exercise of this Warrant, it may be required to hold such securities for an indefinite period.  The Holder also understands that any sale of the shares of Common Stock issuable upon exercise of this Warrant which might be made by it in reliance upon Rule 144 under the Securities Act may be made only in accordance with the terms and conditions of that Rule.

(f)            Accredited Investor.  The Holder is an “accredited investor” within the meaning of Rule 501 of Regulation D under the Securities Act.

(g)           Permitted Designee.  Notwithstanding anything contained herein, the Company shall, upon written request of the original Holder to be delivered to the Company on or before April 15, 2004, permit the original Holder to transfer this Warrant in whole or in part to officers and employees of the original Holder (collectively, “Permitted Designees”) who shall thereafter be bound by the terms of this Warrant; provided, however, the Company shall not be required to issue such Warrants to any person who is not an “accredited investor” within the meaning of Regulation D promulgated under the Securities Act of 1933, as amended (the “Act”) or who has not executed and delivered an Investor Representation Letter and an Investor Questionnaire in form and substance reasonably satisfactory to the Company.
