                     SUPPLEMENT TO DEBT CONVERSION AGREEMENT


         This Supplement to the Debt Conversion Agreement (this "Supplement") is
made to be effective as of the 31st day of December, 2003, (the "Effective
Date") by and between EDT Learning, Inc., a Delaware corporation ("EDT"), Leeds
Equity Partners III, L.P., a Delaware limited partnership ("Leeds"), Investor
Growth Capital Limited, a Guernsey corporation ("IGCLTD") and Investor Group,
L.P., a Guernsey limited partnership ("IGCLP") (IGCLTD AND IGCLP collectively
referred to herein as "IGC"), with IGC and Leeds collectively referred to herein
as "Quisic Investors."

                                 R E C I T A L S

         WHEREAS, EDT entered into agreements with the Quisic Investors (with
these agreements herein after collectively referred to as the "2002 Agreements")
on or about June 14, 2002 whereby the Quisic Investors acquired shares of EDT
common stock. All capitalized terms not defined herein have the meaning given to
them in those respective Agreements.

         WHEREAS, Pursuant to the 2002 Agreements, EDT is obligated to pay the
Quisic Investors an amount of cash that is collected from the Public
Broadcasting Systems ("PBS") Contract.

         WHEREAS, As of the Effective Date, EDT has collected from PBS $300,000
(the "Payment").

         WHEREAS, The Quisic Investors on or before December 31, 2003 entered
into a debt conversion agreement of which a copy is attached as Exhibit A (the
"Debt Conversion Agreement") that was to be final and effective on December 31,
2003 in which the Quisic Investors agreed to convert the Payment due from the
Company into shares of the Company's common stock (the "Shares").

         WHEREAS, The parties wish to provide for further representations and
covenants between the parties to supplement the terms of the Debt Conversion
Agreement.

         NOW THEREFORE, in consideration of the mutual promises and covenants
contained herein and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:

1. CONVERSION ACKNOWLEDGEMENT. The parties hereby confirm and ratify their
agreement to convert the Payment into Shares on the terms specified in the Debt
Conversion Agreement and therefore, EDT will instruct its transfer agent to
deliver to Quisic Investors stock certificates representing an aggregate of
333,333 Shares immediately upon execution of this Supplement, and shall
immediately thereafter cause each Quisic Investor to receive a stock certificate
representing the number of Shares opposite its name on Exhibit B to this
Supplement.

         Each certificate representing Shares issued pursuant to the terms of
this Supplement shall bear the following legend:

                                       2
<PAGE>

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
         INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED. SUCH SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED
         IN THE ABSENCE OF SUCH REGISTRATION WITHOUT AN EXEMPTION UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF LEGAL COUNSEL
         REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT
         REQUIRED."

2. REPRESENTATIONS AND WARRANTIES OF QUISIC INVESTORS. Each Quisic Investor
hereby severally, but not jointly, represents and warrants (with respect to
itself only) to EDT as follows:

         2.1 REQUISITE POWER AND AUTHORITY. Quisic Investor has all necessary
power and authority under all applicable provisions of law to execute, deliver
and perform its obligations under this Supplement and to carry out its
provisions. This Supplement will be the valid and binding obligation of Quisic
Investor, enforceable against Quisic Investor in accordance with its terms,
except (a) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other laws of general application affecting enforcement of
creditors' rights, and (b) general principles of equity that restrict the
availability of equitable remedies.

         2.2 INVESTMENT REPRESENTATIONS. Quisic Investor understands that the
Shares have not been registered under the Securities Act of 1933, as amended
(the "Securities Act"). Quisic Investor also understands that the Shares are
being offered and sold pursuant to an exemption from registration contained in
the Securities Act based in part upon Quisic Investor's representations
contained in this Supplement. Quisic Investor hereby represents and warrants as
follows:

                  (a) QUISIC INVESTOR BEARS ECONOMIC RISK. Quisic Investor has
         substantial experience in evaluating and investing in private placement
         transactions of securities in companies similar to EDT so that it is
         capable of evaluating the merits and risks of its investment in EDT and
         has the capacity to protect its own interests. Quisic Investor must
         bear the economic risk of this investment indefinitely unless the
         Shares are registered pursuant to the Securities Act, or an exemption
         from registration is available.

                  (b) ACQUISITION FOR OWN ACCOUNT. Quisic Investor is acquiring
         the Shares for Quisic Investor's own account for investment only, and
         not with a view towards their distribution in violation of state or
         federal securities laws.

                  (c) ACCREDITED INVESTOR. Quisic Investor represents that it is
         an accredited investor within the meaning of Regulation D under the
         Securities Act.

                  (d) RULE 144. Quisic Investor acknowledges and agrees that the
         Shares will be offered as restricted securities, unless they are
         subsequently registered under the Securities Act or sale pursuant to an
         exemption from such registration is available. Quisic Investor has been
         advised or is aware of the provisions of Rule 144 promulgated under the
         Securities Act as in effect from time to time ("Rule 144"), which
         permits limited resale of shares purchased in a private placement
         subject to the satisfaction of certain conditions, including, among
         other things: the availability of certain current public information
         about EDT, the resale occurring following the required holding period
         under Rule 144 and the number of shares being sold during any
         three-month period not exceeding specified limitations.

                                       3

3. REPRESENTATIONS AND WARRANTIES OF EDT. EDT represents and warrants to Quisic
Investors the following:

         3.1 CORPORATE EXISTENCE: GOOD STANDING. EDT is a corporation duly
organized and existing and in good standing under the laws of the State of
Delaware.

         3.2 POWER AND AUTHORITY. EDT has corporate power to execute, deliver
and perform this Supplement and all agreements and other documents executed and
delivered by it pursuant to this Supplement or to be executed and delivered and
taken all actions required by law, its Certificate of Incorporation, its Bylaws
or otherwise, to authorize the execution, delivery and performance of this
Supplement and such related documents. EDT has the legal capacity to enter into
and perform this Supplement and the other agreements to be executed and
delivered by it in connection herewith. This Supplement and all agreements and
documents executed and delivered in connection herewith have been or will be
duly executed and delivered by EDT, and constitute or will constitute the legal,
valid, and binding obligations of EDT enforceable against EDT in accordance with
their respective terms, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies. The execution and delivery of this
Supplement and the agreements related hereto executed and delivered pursuant to
this Supplement or to be executed and delivered on the Effective Date do not and
the consummation of the transactions contemplated hereby will not, violate any
provision of the Certificate of Incorporation or Bylaws of EDT or any provisions
of, or result in the acceleration of, any obligation under any mortgage, lien,
lease, agreement instrument, order, arbitration award, judgment or decree to
which EDT is a party or by which it is bound, or violate any restrictions of any
kind to which EDT is subject.

         3.3 EDT SHARES. All of the Shares issued to Quisic Investor will be,
when so issued, (i) duly authorized, validly issued, fully paid and
nonassessable and (ii) free of preemptive rights created by statute, EDT's
Certificate of Incorporation or Bylaws or any agreement to which EDT is a party
or by which EDT is bound. All other issued and outstanding shares of common
stock of EDT are duly authorized, fully paid and non-assessable and were issued
in accordance with the registration or qualification provisions of the
Securities Act, and of any relevant state securities laws or pursuant to valid
exemptions therefrom.

         3.4 FINANCIAL STATEMENTS. EDT's audited financial statements for the
fiscal year ended March 31, 2003 and the unaudited financial statements for the
interim period ending December 31, 2003 (the "EDT Financials Date"), reflecting
the results of the operations and financial condition of EDT at such dates have
been prepared in accordance with generally accepted accounting principles,
consistently applied (the "Financial Statements") and are on file with the SEC.
The Financial Statements: (i) fairly and accurately present the financial
position of EDT as of the dates indicated and present the results of EDT's
operations for the periods then ended; and (ii) are in accordance with the books
and records of EDT, as the case may be, which have been properly maintained and
are complete and correct in all material respects.


                                       4
<PAGE>

         3.5 SEC DOCUMENTS AND REPORTS. EDT has filed all required documents
with the Securities and Exchange Commission (the "SEC") (the "SEC Documents").
As of their respective dates, the SEC Documents complied in all material
respects with the requirements of the Securities Act or the Securities Exchange
Act of 1934, as amended, as the case may be, and, at the respective times they
were filed, none of the SEC Documents contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

4. QUISIC INVESTORS' REGISTRATION RIGHTS.

         4.1 EDT will file with the SEC within fifteen (15) days from execution
of this Supplement, a registration statement (the "Registration Statement")
registering the sale under the Securities Act of the Shares issued to Quisic
Investors pursuant to the terms of this Supplement, and will use its reasonable
best efforts to have the Registration Statement declared effective, and cause
said registration statement to remain effective until the earliest of (i) two
(2) years after the date it is declared effective, (ii) the date all the Shares
registered thereby have been sold, or, (iii) in the reasonable opinion of EDT's
counsel, which opinion shall qualify as a satisfactory opinion of counsel
pursuant to the legend condition hereof, the Shares may be sold publicly without
registration. Each Quisic Investor will, in a timely fashion, provide EDT and
its counsel with such information and execute such documents as EDT's counsel
may reasonably require to prepare and to process the Registration Statement.

         4.2 EDT will bear all expenses (except underwriting discounts and
commission, if any, and the legal fees and expenses, if any, of counsel to
Quisic Investors) necessary and incidental to the performance of its obligations
under this Section.

         4.3 Anything to the contrary notwithstanding, EDT shall not be required
to register any Shares issued to any Quisic Investor pursuant to the terms of
this Supplement or provide notices under this Supplement to any Quisic Investor
if such Shares are either (i) covered by a then currently effective registration
statement or (ii) in the reasonable opinion of EDT's counsel, may be sold
pursuant to the exemption from registration provided by Section (k) of Rule 144.

5. MISCELLANEOUS.

         5.1 SUCCESSORS AND ASSIGNS. This Supplement shall not be assignable, by
operation of law or otherwise, without the prior written consent of all parties.
Subject to the foregoing, this Supplement shall inure to the benefit of, be
enforceable by and be binding upon the parties, their successors and permitted
assigns.

         5.2 ENTIRE AGREEMENT. This Supplement, the Debt Conversion Agreement,
and the Exhibits hereto contain and constitute the entire agreement among the
parties hereto relating to the subject mater hereof. Neither this Supplement nor
any provision hereof may be changed, waived, discharged or terminated orally,
but only by an agreement in writing signed by the party against whom or which
the enforcement of such change, waiver, discharge or termination is sought.

shall govern the relative rights, obligations, powers, duties and other internal
affairs of such party and its board of directors.

         5.4 COUNTERPARTS. This Supplement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same agreement.
