                     LOAN EXTENSION AND CONVERSION AGREEMENT

      This Extension and Conversion Agreement ("Agreement") is entered into as
of June 29, 2003, by and between Frastacky Associates, Inc. ("Frastacky") and
Interchange Corporation (formerly known as eLibration.com Corporation), a
Delaware corporation (the "Company") to provide for the extension of the
maturity date and conversion of the outstanding balance of principal and accrued
interest under the promissory notes ("Notes") made by the Company in favor of
Frastacky, on the following terms and conditions:

      1. Notes. The Notes which are the subject of this Agreement are the
following: (a) that certain Promissory Note dated August 15, 2001, in the
principal sum of $350,000, (b) that certain Promissory Note dated October 24,
2001 in the principal sum of $125,000, (c) that certain Promissory Note dated
November 28, 2001 in the principal sum of $75,000, (d) that certain Promissory
Note dated November 21, 2002 in the principal sum of $250,000, (e) that certain
Promissory Note dated January 17, 2003, in the principal sum of $150,000, and
(f) that certain Promissory Note dated January 30, 2003, in the principal sum of
$250,000. Each of the Notes is secured by a written Security Agreement dated
August 15, 2001.

      2. Extension of Maturity Date. The "Maturity Date" of each of the Notes is
hereby extended to April 30, 2004; provided that (a) it shall be an additional
Event of Default under each of the Notes if gross proceeds of at least
$1,000,000 are not received by the Company from an offering of its securities
arranged by GunnAllen Financial, Inc. on or before October 1, 2003, and (b)
Frastacky may declare all of the Notes to be in default if an Event of Default
occurs under any of the Notes prior to the Maturity Date.

      3. Conversion Right. At the sole option of Frastacky, the outstanding
balance of principal and interest due under the Notes ("Conversion Amount") may
be converted into shares of the Company's common stock ("Converted Shares") at a
purchase price of $0.50 per share, at any time prior to payment in full of the
Notes. To effect such conversion, Frastacky shall deliver the Notes to the
Company for cancellation together with written notice of conversion. The Company
shall, no later than ten (10) business days after receipt of the Notes and
notice of conversion, cancel the Notes and issue to Frastacky or the holder of
the Notes stock certificates representing the Converted Shares. If any change is
made in the Company's common stock (through reorganization, recapitalization,
stock dividend, dividend in property other than cash, stock split or reverse
stock split, liquidating dividend, combination of shares, exchange of shares,
change in corporate structure or otherwise), the class and number of shares and
price per share of Common Stock subject to conversion will be appropriately
adjusted.

      4. Piggyback Registration. As a material inducement for Frastacky to enter
into this Agreement, the Company agrees to provide "piggyback" registration
rights as follows: At such time as the Company first files for registration of
shares of any class of stock of the Company under the Securities Act of 1933, as
amended, except for newly issued shares to be offered pursuant to an Initial
Public Offering, the Company shall include in such registration not less than
the number of the Converted Shares which when multiplied by the last price per
share of the Company's common stock sold by the Company prior to the
registration filing equals the Conversion Amount. For example, if the Conversion
Amount is $1,400,000 on the date that Frastacky delivers its written notice of
conversion and the last price per share of the Company's common stock sold by
the Company prior to the registration filing is $2.00, then the Company shall
register not less than 700,000 of the Converted Shares pursuant to this
paragraph. All fees, charges, costs and expenses of any kind (including legal
fees) in connection with such piggyback registration shall be borne by the
Company.

          the Company. The person signing this Agreement on behalf of the
          Company is duly authorized to do so.

      6. Interests Affected. Except as expressly modified by this Agreement, the
Notes and Security Agreement remain fully enforceable in accordance with their
terms. Except for rights expressly evidenced by the Notes, this Agreement does
not affect any other interests or rights which Frastacky has relating to the
Company. Without limitation, this Agreement does not affect the other shares of
stock of the Company held by Frastacky, the warrants to acquire shares of stock
of the Company held by Frastacky or the registration rights of Frastacky.

expenses are subject to reimbursement hereunder, and provided, further, that in
no event shall such expenses exceed $1,500.

entitled to the registration rights set forth below with respect to the shares
of Common Stock issuable upon both the conversion of the Notes and the exercise
of Warrants (collectively, for purposes of this Section the "Underlying
Shares").

            (a) "Piggyback" Registration Rights. At any time commencing six
months after the Company has completed an initial public offering ("IPO"), if
the Company shall determine to proceed with the actual preparation and filing of
a new registration statement under the 1933 Act in connection with the proposed
offer and sale of any of its securities by it or any of its security holders
(other than a registration statement on Form S-4), the Company will give written
notice of its determination to all record holders (the "Holders") of the
Underlying Shares. Upon the written request from any of such holders (the
"Requesting Holders"), within fifteen (15) days after receipt of any such notice
from the Company, the Company will, except as herein provided, cause all of the
Underlying Shares covered by such request (the "(A) "Piggyback" Registration
Rights. At any time commencing six months after the Company has completed an
initial public offering ("IPO"), if the Company shall determine to proceed with
the actual preparation and filing of a new registration statement under the 1933
Act in connection with the proposed offer and sale of any of its securities by
it or any of its security holders (other than a registration statement on Form
S-4), the Company will give written notice of its determination to all record
holders (the "Holders") of the Underlying Shares. Upon the written request from
any of such holders (the "Requesting Holders"), within fifteen (15) days after
receipt of any such notice from the Company, the Company will, except as herein
provided, cause all of the Underlying Shares covered by such request (the
"Requested Stock") held by the Requesting Holders to be included in such
registration statement, all to the extent requisite to permit the sale or other
disposition by the prospective seller or sellers of the Requested Stock;
provided, however, that nothing herein shall prevent the Company from, at any
time, abandoning or delaying any registration. If any registration pursuant to
this Section 4.1 shall be underwritten in whole or in part, the Company may
require that the Requested Stock be included in the underwriting on the same
terms and conditions as the securities otherwise being sold through the
underwriters. In such event, the Requesting Holders shall, if requested by the
underwriters, execute an underwriting agreement containing customary
representations and warranties by selling stockholders. If in the good faith
judgment of the managing underwriter of such public offering the inclusion of
all of the Requested Stock would reduce the number of shares to be offered by
the Company or interfere with the successful marketing of the shares of stock
offered by the Company, the number of shares of Requested Stock otherwise to be
included in the underwritten public offering may be reduced pro rata (by number
of shares) among the Requesting Holders and all other holders of registration
rights who have requested inclusion of their securities and whose registration
rights are not superior to those of the Holders, or excluded in their entirety
if so required by the underwriter. The obligation of the Company under this
Section 4.1 shall not apply after the earlier of (a) the date that all of the
Underlying Shares have been sold pursuant to Rule 144 under the 1933 Act or an
effective registration statement, or (b) such time as the Underlying Shares held
by any Holder (i) are eligible for immediate resale pursuant to Rule 144(k)
under the 1933 Act or (ii) are otherwise eligible for resale pursuant to Rule
144(k) within a period of three months..

<PAGE>

            (b)   Automatic Registration. In the event that prior to the IPO
referred to in paragraph A above the Company voluntarily or is required to file
periodic reports with the Securities and Exchange Commission under the
Securities and Exchange Act of 1934, as amended, the Company shall, within 180
days of such date that reports are first filed, file a registration statement on
appropriate form so as to provide for the resale by the holders of the
Underlying shares to sell such securities pursuant to the Securities Act of
1933.

            REGISTRATION PROCEDURES. To the extent required by Section 5 hereof,
the Company will:

      prepare and file with the SEC a registration statement with respect to
such securities, and use its best efforts to cause such registration statement
to become and remain effective for the longer of (i)at least ninety (90) days or
(ii) the unexpired term of the Warrants;

that the Company shall not for any purpose be required to execute a general
consent to service of process or to qualify to do business as a foreign

which, in the opinion of counsel for such Holders (and concurred in by counsel
for the Company), is required under the 1933 Act or the rules and regulations
thereunder in connection with the distribution of Common Stock by such Holders;

      prepare and promptly file with the SEC and promptly notify such Holders of
the filing of such amendment or supplement to such registration statement or
prospectus as may be necessary to correct any statements or omissions if, at the
time when a prospectus relating to such securities is required to be delivered
under the 1933 Act, any event shall have occurred as the result of which any
such prospectus or any other prospectus as then in effect would include an
untrue statement of a material fact or omit to state any material fact necessary

Section 4.1 hereof, all fees, costs and expenses of and incidental to such
registration, inclusion and public offering in connection therewith shall be

expressly included above.

contained in such registration statement, any prospectus contained therein or
any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was so made in reliance upon and in
strict conformity with written information furnished by or on behalf of such
Holder specifically for use in the preparation thereof.

      Promptly after receipt by an indemnified party pursuant to the provisions
of paragraph (a) or (b) of this Section 4.4 of notice of the commencement of any
action involving the subject matter of the foregoing indemnity provisions such
indemnified party will, if a claim thereof is to be made against the
indemnifying party pursuant to the provisions of said paragraph (a) or (b),
promptly notify the indemnifying party of the commencement thereof; but the
omission to so notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise under this
Section except to the extent the defense of the claim is prejudiced. In case
such action is brought against any indemnified party and it notifies the
indemnifying party of the commencement thereof, the indemnifying party shall
have the right to participate in, and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party,
provided, however, if counsel for the indemnifying party concludes that a single
counsel cannot under applicable legal and ethical considerations, represent both
the indemnifying party and the indemnified party, the indemnified party or
parties have the right to select separate counsel to participate in the defense
of such action on behalf of such indemnified party or parties; provided that
there shall be no more than one such separate counsel. After notice from the
indemnifying party to such indemnified party of its election so to assume the
defense

<PAGE>

thereof, the indemnifying party will not be liable to such indemnified
party pursuant to the provisions of said paragraph (a) or (b) for any legal or
other expense subsequently incurred by such indemnified party in connection with
the defense thereof other than reasonable costs of investigation, unless (i) the
indemnified party shall have employed counsel in accordance with the provisions
of the preceding sentence, (ii) the indemnifying party shall not have employed
counsel reasonably satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after the notice of the commencement
of the action or (iii) the indemnifying party has, in its sole discretion,
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party.
