SUBLEASE AGREEMENT

THIS SUBLEASE AGREEMENT (“Sublease”) made as of the 28th day of July, 2006 by and between Omtool, Ltd., a Delaware corporation (hereinafter “Omtool” or “Sublessor”) with a principal place of business at 6 Riverside Drive, Andover, MA 01810 and eSped.com, Inc., a Delaware corporation (hereinafter “eSped” or “Sublessee”) with a place of business at 8A Industrial Way Salem, NH 03079.

WHEREAS Omtool has leased approximately 44,048 square rentable feet of space (the “Omtool Premises”) located on the first and second floors of the building located at 6 Riverside Drive, Andover, MA (the “Building”) pursuant to that certain Lease Agreement dated January 6, 2006 (as the same may be modified or amended from time to time, the “Lease”) by and between Omtool, as tenant, and SFI I, LLC, as landlord (herein “Landlord”).  A copy of the Lease is annexed hereto as Exhibit A; and

WHEREAS eSped desires to sublease from Omtool, and Omtool desires to sublease to eSped, a portion of the Omtool Premises consisting of approximate seven thousand twenty five (7,025) rentable square feet of space, as more particularly described on Exhibit B attached hereto (the “Subleased Premises”), all subject to and in accordance with the provisions of this Sublease;

NOW THEREFORE, for Ten Dollars ($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby mutually acknowledged, Sublessor and Sublessee hereby covenant and agree as follows:

1.             Capitalized terms used in this Sublease and not otherwise defined herein shall have the meanings ascribed to such terms in the Lease.

2.             REFERENCE DATA.

2

3.             Sublessor hereby leases to Sublessee, and Sublessee hereby leases from Sublessor, the Subleased Premises and the common areas (to be used in common with others entitled thereto) more specifically described in the Lease for the Permitted Uses.

4.             The Term of this Sublease shall be for a period of fifty-eight (58) months commencing on the Commencement Date and terminating on the last calendar day of the fifty-eighth (58th) month of the Term, unless earlier terminated in accordance with the provisions hereof.

5.             Sublessee covenants and agrees to pay to Sublessor Base Rent in the amounts set forth above for so long as this Sublease remains in full force and effect.  Each payment of Base Rent shall be made in advance on or before the first day of each calendar month of the Term at Sublessor’s address shown herein or at such place as Sublessor shall from time to time designate in writing and otherwise in accordance with the provisions of the Lease.

6.             Sublessee shall pay to Sublessor as additional rent (“Additional Rent”) eSped’s Pro Rata Share of Operating Costs and Taxes.  Sublessor may make a good faith estimate of the Additional Rent to be due by Sublessee for any calendar year or part thereof during the Term.  During each calendar year or partial calendar year of the Term, Sublessee shall pay to Sublessor, in advance concurrently with each monthly installment of Base Rent, an amount equal to the estimated Additional Rent for such calendar year or part thereof divided by the number of months therein.  Sublessor and Sublessee agree that eSped’s estimated Pro Rata Share of Operating Costs and Taxes for the first Lease Year shall be $3.67 and $2.06 per rentable square foot of Subleased Premises, respectively; and accordingly, eSped shall pay to Sublessor, in advance concurrently with each monthly installment of Base Rent, $5.73 per rentable square foot of Subleased Premises as Additional Rent hereunder during the first lease year.  From time to time, Sublessor may estimate and re-estimate the Additional Rent to be due by Sublessee and deliver a copy of the estimate or re-estimate to Sublessee.  Thereafter, the monthly installments of Additional Rent payable by Sublessee shall be appropriately adjusted in accordance with the estimations so that, by the end of the calendar year in question, Sublessee shall have paid all of the Additional Rent as estimated by Sublessor.  Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Operating Costs  and Taxes are available for each calendar year or tax year, as applicable.  By May 1 of each calendar year, or as soon thereafter as practicable, Sublessor shall furnish to Sublessee a statement of Operating Costs for the previous year and of the Taxes for the previous year (the “Operating Costs and Tax Statement”).  If Sublessee’s estimated payments of Operating Costs or Taxes under this Section 6 for the year covered by the Operating Costs and Tax Statement exceed Subtenant’s share of such items as indicated in the Operating Costs and Tax Statement, then Sublessor shall promptly credit or reimburse Sublessee for such excess; likewise, if Sublessee’s estimated payments of Operating Costs or Taxes under this Section 6 for such year are less than Sublessee’s share of such items as indicated in the Operating Costs and Tax Statement, then Sublessee shall, within not more than ten (10) business days, pay Sublessor such deficiency.

3

Sublessee shall also pay to Sublessor, as Additional Rent, any additional operating expenses agreed by Sublessor and Sublessee to be required to keep the Building in good operating condition.

7.             Security Deposit.  [intentionally omitted].

8.             Additional Sublessee Covenants.  Sublessee hereby covenants:

(a)           To comply with the terms and provisions of the Lease applicable to the Subleased Premises except as specifically modified by provisions of this Sublease, and to do nothing which will subject the Lease to termination by Landlord under the provisions of the Lease.
