THOUSAND DOLLARS ($6,500,000), or so much thereof as shall be outstanding, in lawful money of the United States of America and in immediately available funds, on September 15, 2004 (the
"Maturity Date") in one lump-sum payment of $6,500,000 (or so much thereof as shall be outstanding), and from and after the date of this
Convertible Subordinated Promissory Note to pay interest on the principal amount hereof outstanding from time to time, at Borrower's election in cash or in eSoft Common Stock, par value $0.01 per
share ("Common Stock"), at the Fair Market Value (as defined in the next paragraph) at such office, at the rate per annum of seven percent (7.0%), in
arrears on a quarterly basis on the 15th day of each December, March, June and September, commencing December 15, 2001;provided, however, that
the principal amount hereof was $12,500,000 between September 15, 2001 and November 20, 2001, and thereafter the principal
amount hereof was reduced to $6,500,000 pursuant to a prepayment of principal by the Borrower and the forgiveness of certain indebtedness by the Lender (as described in that certain Note Prepayment
and Amendment Agreement, dated as of November 20, 2001, between Borrower and Lender).

Capitalized
terms not otherwise defined herein shall have the respective meanings assigned to them in the Stock and Warrant Purchase and Investor Rights Agreement dated April 26,
2000 between the Borrower and the Lender, as amended on September 15, 2000 (the "Purchase Agreement"). For purposes of this Convertible
Subordinated Promissory Note, "Fair Market Value" of the Common Stock shall be determined by the average of the closing prices of the Common Stock on
the principal securities exchange or market on which it is then being listed for the ten (10) trading days preceding the date of determination of the Fair Market Value.

Unless
all or part of the principal amount of this Convertible Subordinated Promissory Note is converted to the Borrower's Common Stock by the Lender on or before the Maturity Date as
provided for herein, all outstanding principal and accrued interest hereunder shall be due and payable on the Maturity Date. The Borrower may not prepay all or any part of the principal amount of this
Convertible Subordinated Promissory Note before maturity. The loan represented by this Convertible Subordinated Promissory Note shall be subordinated to all other debt of the Borrower outstanding at
any time.

A.Payments:All payments of principal, interest and other amounts to be made by the Borrower under this
Convertible Subordinated Promissory Note shall be made, (i) if in cash in immediately available funds to the Lender no later than 1:00 p.m. local time in Broomfield, Colorado, on the
date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding business day), and (ii) if in stock to
the Lender no later than 1:00 p.m. local time in Broomfield, Colorado, five (5) business days following the date on which such payment shall become due (each such payment made
after such time on such due date to be deemed to have been made on the next succeeding business day). If an Event of Default (as defined below) has occurred and is continuing, the Lender may apply any
such payment as it may elect in its discretion. If the due date of any payment under this Agreement or the Note would otherwise fall on a day that is not a business day, such date shall be extended to
the next succeeding business day and

---

interest shall be payable for any principal so extended for the period of such extension. Interest shall be computed on the basis of the actual days elapsed (including the first day but
excluding the last day) occurring in the period for which payable, relative to a year of 365 or 366 days, as the case may be.

B.Conversion:The aggregate amount of outstanding principal of this Convertible Subordinated Promissory Note
plus accrued and unpaid interest is convertible, in whole or in part, at the option of the Lender, at any time commencing on the date of issuance of this Convertible Subordinated Promissory Note and
ending on the Maturity Date, as follows:

1.Mechanics of Conversion.The Lender shall notify the Borrower in writing (the
"Conversion Notice"), in the manner prescribed in Section 11(e) of the Purchase Agreement, of its desire to convert all or part of the
aggregate amount of principal of this Convertible Subordinated Promissory Note plus interest, if any, that has accrued but remains unpaid thereon. The Conversion Notice shall be accompanied by the
original of this Convertible Subordinated Promissory Note (or reasonable written assurance of the loss or destruction of the original of this Convertible Subordinated Promissory Note). The Conversion
Notice shall specify (i) the aggregate amount of principal of this Convertible Subordinated Promissory Note plus interest, if any, that has accrued but remains unpaid thereon to be converted
(the "Conversion Amount"), (ii) the date of the desired conversion (the "Conversion Date") and
(iii) the name(s) which should appear on the stock certificate(s) to be issued by the Borrower which represent the Common Stock acquired by the Lender upon conversion. If reasonably required by
the Borrower, certificates surrendered for conversion shall be accompanied by a written instrument or instruments of transfer in form reasonably satisfactory to the Borrower. The Borrower shall not be
required to pay any tax that may be payable in respect of any transfer involving the issuance and delivery of such certificates upon conversion in a name other than that of the Lender, and the
Borrower shall not be required to issue or deliver such certificates unless or until the persons requesting the issuance thereof shall have established to the Borrower's reasonable satisfaction that
any such taxes have been paid or will be paid by parties other than the Borrower.

2.Common Stock Issuable upon Conversion.Within three (3) business days of receipt of a
Conversion Notice, the Borrower shall issue to the Lender that number of shares of Common Stock determined by dividing the Conversion Amount by the Fair Market Value of the Common Stock as of the
Conversion Date (the "Conversion Price"). If the calculation of the Conversion Price set forth in the preceding sentence would result in a Conversion
Price of less than $11.00 (as adjusted for stock splits, stock dividends, recapitalizations and the like), then the Conversion Price shall instead be $11.00 (as adjusted for stock splits, stock
dividends, recapitalizations and the like). If the calculation of the Conversion Price set forth in the second preceding sentence would result in a Conversion Price of greater than $19.507 (as
adjusted for stock splits, stock dividends, recapitalizations and the like), then the Conversion Price shall instead be $19.507 (as adjusted for stock splits, stock dividends, recapitalizations and
the like). The Conversion Price shall be subject to adjustment as set forth below. If less than the entire outstanding principal amount of this Convertible Subordinated Promissory Note is being
converted, a new Convertible Subordinated Promissory Note shall promptly be delivered to the Lender for the unconverted principal balance and shall be of like tenor as to all terms as the Convertible
Subordinated Promissory Note surrendered.

shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to the Holders in respect of this Convertible Subordinated Promissory Note, unless and
until the Holders shall have received written notice thereof from the Borrower or a holder of Senior Indebtedness; and, prior to the receipt of any
such written notice, the Holders shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Holders shall not have received the notice provided for in this

trustee, custodian, assignee for the benefit of the creditors, agent or other person making such payment or distribution, delivered to the holders of this Convertible Subordinated Promissory Note, for
the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Borrower, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Section D.

None
of the terms or provisions of this Convertible Subordinated Promissory Note may be amended, modified or waived except by a written agreement duly executed on behalf of the Lender
and the Borrower and specifically setting forth the provision so amended, modified or waived. No failure on the part of the Lender to exercise and no delay in exercising, and no course of dealing with
respect to any right, power or privilege under this Convertible Subordinated Promissory Note shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or
privilege under this Convertible
Subordinated Promissory Note preclude any other or further exercise thereof or the exercise of any other right, power or privilege.
