                  (a) REDEMPTION OF THE DEBENTURE; TERMINATION OF TRANSACTION
DOCUMENTS. Subject to and immediately prior to the consummation of the Merger
and subject to the satisfaction or waiver of the conditions set forth in

following the consummation of the Merger (the "E-STAMP SHARES") (for purposes of
such calculation, treating as issued and outstanding immediately following the
consummation of the Merger all shares of E-Stamp Common Stock issuable upon the
exercise of outstanding options and warrants (including options and warrants to
purchase shares of E-Stamp Common Stock which were issued pursuant to the terms
of the Merger Agreement in exchange for options and warrants to purchase shares
of Company Common Stock) which were included in the definition of "E-Stamp Total
Outstanding Shares" and/or "Learn2 Total Outstanding Shares" (as each such term
is defined in the Merger Agreement) immediately prior to the consummation of the
Merger). The issuance of the E-Stamp Shares to RGC shall be registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), pursuant to that
certain Registration Statement on Form S-4 to be filed by E-Stamp pursuant to
the Merger Agreement. The E-Stamp Shares shall be freely tradeable by RGC
without restriction under the Securities Act (except as provided by Rule 145
promulgated under the Securities Act and by this Agreement). E-Stamp agrees to
register the resale by RGC of the E-Stamp Shares under the Securities Act in
accordance with the terms and provisions set forth in that certain Registration
Rights Agreement of even date herewith by and between E-Stamp and RGC in the
form attached hereto as EXHIBIT D (the "E-STAMP REGISTRATION RIGHTS AGREEMENT").
Subject to the satisfaction or waiver of the conditions set forth in Sections 5
and 6 hereof, the closing of the redemption of the Debenture (the "CLOSING")
shall take place concurrent with the closing of the Merger at the offices of
Swidler Berlin Shereff Friedman LLP, 405 Lexington Avenue, New York, New York
10174 or at such other place as is agreed to by the parties hereto. Upon receipt
by RGC of such $1,000,000 and the Company Shares and concurrent with the Merger,
the Debenture shall be redeemed, the Transaction Documents shall


                                       2
<PAGE>

terminate and RGC shall have no further rights or remedies against the Company
and E-Stamp under the Transaction Documents.

                  (b) RETENTION OF RIGHTS. Subject to the terms and conditions
of the Waiver attached hereto as EXHIBIT E, RGC shall retain all of its rights
and remedies set forth in the Debenture and the Transaction Documents until such
time as the Debenture is redeemed pursuant to the terms and conditions of this
Agreement.

                  (c) TRADING LIMITATIONS. In the event that the Merger is
consummated and subject to the conditions set forth in the last sentence of this

of E-Stamp Common Stock in compliance with all relevant securities laws and
regulations and will not create any daily low trading prices in the E-Stamp
Common Stock, (ii) until one hundred eighty (180) days from the closing of the
Merger, it will not engage in any Sales of E-Stamp Common Stock, and (iii)

Merger, its Sales of E-Stamp Common Stock in any calendar month will not exceed
5% of the lesser of (a) the total trading volume of the E-Stamp Common Stock for
the previous calendar month and (b) the aggregate number of shares of E-Stamp
Common Stock beneficially owned by RGC immediately following the consummation of
the Merger; PROVIDED, HOWEVER, that the foregoing trading limitations shall not
prevent RGC from selling up to 5% of the aggregate trading volume in any Trading
Day (as defined in the Debenture); and, PROVIDED FURTHER, HOWEVER, that the
foregoing trading limitations shall not apply to block sales of at least 25,000
shares of E-Stamp Common Stock to a single purchaser (who is not an "affiliate"
(as such term is defined in the Securities Act) of RGC) at a price greater than
the immediately preceding sale price of E-Stamp Common Stock on the principal
securities exchange or trading market where such security is listed or traded as
reported by Bloomberg Financial Markets, PROVIDED that the aggregate block sales
effected by RGC in any calendar month will not exceed 15% of the total trading
volume of the E-Stamp Common Stock for the previous calendar month. The
restrictions set forth in clauses (i), (ii) and (iii) above shall only apply to
RGC if (x) each of the officers and directors of the Company and E-Stamp who are
serving in such capacity as of the date hereof and (y) each of the holders of

owned by them; PROVIDED, HOWEVER, that (1) in the case of any such officer,
director or five percent (5%) holder, the limitation referred to in subpart (b)
of clause (iii) above shall be deemed to refer to the aggregate number of shares
of E-Stamp Common Stock beneficially owned by such officer, director or five
percent (5%) holder immediately following the consummation of the Merger, (2)
the exceptions set forth in the provisos to clause (iii) above shall not apply
to Sales by any such officer or director and (3) notwithstanding the limitation
referred to in subpart (b) of clause (iii) above (but subject to the limitation
referred to in subpart (a) of clause (iii) above), each such officer and
director shall be permitted to sell up to 5,000 shares of E-Stamp Common Stock
(as adjusted for stock splits, stock dividends and similar events) in any
calendar month during the period specified in clause (iii) above; and, PROVIDED
FURTHER, that such restrictions shall expire with respect to any officer or
director (other than Stephen Gott and Donald Schupak) whose employment with or
service to the Company or E-Stamp is subsequently terminated, so long as such
officer or director is not (or would not be following consummation of the
Merger), at the time of such termination, a holder


                                       3
<PAGE>

of five percent (5%) or more of the outstanding shares of E-Stamp Common Stock.
"SALE", for purposes of this Section 1(c), shall mean the sale, assignment,
transfer, or other disposition of, or the entering into of any contract, option
or other agreement or understanding (including, without limitation, any short
sale (whether or not against the box) or any purchase, sale or grant of any
right (including, without limitation, any put or call option) with respect to
any security (other than a broad-based market basket or index) that includes,
relates to or derives any significant part of its value from E-Stamp Common
Stock) with respect to the direct or indirect sale, assignment, transfer or
other disposition of shares of E-Stamp Common Stock; PROVIDED, HOWEVER, that the
term "SALES" shall not include the pledge by RGC of the E-Stamp Shares as
collateral in connection with a BONA FIDE margin account or other lending
arrangement.

                  (d) NOTE. RGC acknowledges and consents to the issuance of the
Note to E-Stamp, the incurrence of the debt covered by the Note, and all related
transactions (including without limitation the grant of the option to E-Stamp to
purchase the Company's property located at One American Way, Pryor, Oklahoma
74361). RGC further agrees that the Note shall rank PARI PASSU and equal in
right of payment with the indebtedness of the Company evidenced by the
Debenture.

termination, amendment, acceleration or cancellation of, any agreement,
indenture, patent, patent license or instrument to which RGC or any of its
affiliates is a party (except for such conflicts, defaults, terminations,
amendments, accelerations and cancellations as would not, individually or in the

                                       4

and not with respect to the other) that:

                  (a) ORGANIZATION AND QUALIFICATION. Each of the Company and

issued to RGC are duly authorized and reserved for issuance and, upon issuance
in accordance with the terms hereof, will be validly issued, fully paid and
non-assessable, and free from all taxes, liens, claims and encumbrances and
shall not be subject to preemptive rights or other similar rights of


                                       5
<PAGE>

stockholders of the Company or E-Stamp and will not impose personal liability
upon the holder thereof.

                  (d) NO CONFLICTS. The execution, delivery and performance of
this Agreement and the E-Stamp Registration Rights Agreement by the Company and
E-Stamp and the consummation by the Company and E-Stamp of the transactions

their respective subsidiaries or by which any property or asset of the Company
or E-Stamp or any of their respective subsidiaries is bound or affected (except,

notification filings, if any, with the Nasdaq National Market or such national
securities exchange, automated quotation system or bulletin board, and the
requirement to file a Form S-4 containing a proxy statement/prospectus with the
Securities and Exchange Commission).

                  (e) NO INVESTMENT COMPANY. E-Stamp is not, and upon the
consummation of the Merger will not be, an "investment company" required to be

<PAGE>

3(f), as of the date of this Agreement, (i) there are no outstanding options,
warrants, scrip, rights to subscribe for, puts, calls, rights of first refusal,
agreements, understandings, claims or other commitments or rights of any
character whatsoever relating to, or securities or rights convertible into or
exchangeable for any shares of capital stock of the Company or any of its
subsidiaries, or arrangements by which the Company or any of its subsidiaries is
or may become bound to issue additional shares of capital stock of the Company
or any of its subsidiaries, (ii) there are no agreements or arrangements under
which the Company or any of its subsidiaries is obligated to register the sale
of any of its or their securities under the Securities Act (except the
Registration Rights Agreement) and (iii) there are no anti-dilution or price
adjustment provisions contained in any security issued by the Company (or in any
agreement providing rights to security holders) that will be triggered by the
redemption of the Debenture. The Company has furnished to RGC true and correct
copies of the Company's Certificate of Incorporation as in effect on the date
hereof ("CERTIFICATE OF INCORPORATION"), the Company's By-laws, as in effect on
the date hereof (the "BY-LAWS"), and the terms of all securities convertible
into or exercisable for Company Common Stock and the material rights of the
holders thereof in respect thereto (including any planned changes to the
exercise price or vesting schedule of any outstanding options or warrants). The
Company shall provide RGC with a written update of this representation signed by
the Company's President and Chief Executive or Chief Financial Officer on behalf
of the Company as of the closing date of the Merger.

            4. COVENANTS.

                  (a) LISTING. E-Stamp shall promptly secure the listing of the
E-Stamp Shares upon each national securities exchange or automated quotation
system (including the Nasdaq SmallCap Market), if any, upon which shares of
E-Stamp Common Stock are then listed (subject to official notice of issuance)
and, so long as RGC owns the E-Stamp Shares, shall maintain, so long as any
other shares of E-Stamp Common Stock shall be so listed, such listing of the
E-Stamp Shares. E-Stamp will obtain and, for two (2) years following the
consummation of the Merger, maintain the listing and trading of the E-Stamp
Common Stock (or the capital stock of any successor entity) on the Nasdaq
National Market (the "NNM"), the Nasdaq SmallCap Market, the New York Stock
Exchange, the American Stock Exchange or the Over-the-Counter Bulletin Board and
will comply in all respects with E-Stamp's reporting, filing and other
obligations under the bylaws or rules of the National Association of Securities
Dealers and such exchanges, as applicable. Following the consummation of the
Merger, at RGC's request, E-Stamp shall promptly provide to RGC copies of any
notices it receives from the NNM and any other exchanges or quotation systems on
which the E-Stamp Common Stock is then listed regarding the continued
eligibility of the E-Stamp Common Stock for listing on such exchanges and
quotation systems.

                  (b) TRANSFER AGENT INSTRUCTIONS. E-Stamp shall issue
irrevocable instructions to its transfer agent to issue unlegended certificates,
registered in the name of RGC or its nominee, for the E-Stamp Shares in such
amounts as may be specified from time to time by RGC (the "IRREVOCABLE TRANSFER
AGENT INSTRUCTIONS"), so long as (i) the E-Stamp Shares are registered for
resale by RGC pursuant to an effective registration statement under the
Securities Act of 1933, as amended, or otherwise may be sold under Rule 144
promulgated under the Securities Act of 1933, as amended ("RULE 144"), without
any restriction as to the number of securities as of a particular date that can
then be immediately sold, (ii) RGC provides E-Stamp


                                       7
<PAGE>

with an opinion of counsel, in form, substance and scope customary for opinions
of counsel in comparable transactions, to the effect that a public sale or
transfer of such E-Stamp Shares may be made without registration under the
Securities Act of 1933, as amended, and such sale or transfer is effected or
(iii) RGC has provided E-Stamp with reasonable assurances that such E-Stamp
Shares can be sold pursuant to Rule 144 or Rule 145, as applicable. E-Stamp
acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to RGC by obliterating the intent and purpose of the
transaction contemplated hereby. Accordingly, E-Stamp acknowledges that the
remedy at law for a breach of its obligations under this Section 4(b) will be
inadequate and agrees, in the event of a breach or threatened breach by E-Stamp
of the provisions of this Section 4(b), that RGC shall be entitled, in addition
to all other available remedies at law or in equity, to an injunction or
injunctions to prevent, cure or restrain any such breach and to enforce
specifically the terms and provisions of this Section 4(b), without the
necessity of showing economic loss and without any bond or other security being
required.

                  (c) APPROVAL OF MERGER; STOCKHOLDER APPROVALS. Subject to the
terms of the Merger Agreement, the Company and E-Stamp shall use their
respective best efforts to consummate the Merger and obtain the stockholder
approvals referred to in Section 3(b) hereof.

                  (d) TRANSFER OF DEBENTURE OR 2000 WARRANT. RGC agrees that,
prior to the consummation of the Merger, it will not transfer the Debenture or
the 2000 Warrant unless the transferee agrees to be bound by the provisions of
this Agreement.

                  (e) TRANSFER OR RESALE. RGC has been advised that RGC may be
deemed to be an "affiliate" of the Company at the effective time of the Merger,
as the term "affiliate" is used for purposes of paragraphs (c) and (d) of Rule
145 promulgated under the Securities Act, although nothing contained herein
shall be construed as an admission by RGC that RGC is in fact an "affiliate" of
the Company. RGC accordingly agrees that, in addition to the restrictions set
forth in Section 1(c) of this Agreement, RGC will not transfer any of the
E-Stamp Shares unless (a) such transfer is made in conformity with the
requirements of Rule 145(d) promulgated under the Securities Act, (b) such
E-Stamp Shares are sold pursuant to an effective registration statement under
the Securities Act, (c) RGC delivers to E-Stamp a written opinion of counsel,
reasonably acceptable to E-Stamp in form and substance, that such sale, transfer
or other disposition is otherwise exempt from registration under the Securities
Act, or (d) the E-Stamp Shares are sold pursuant to Rule 144. Notwithstanding
the foregoing or anything else contained herein to the contrary, the E-Stamp
Shares may be pledged as collateral in connection with a BONA FIDE margin
account or other lending arrangement. RGC agrees to sell the E-Stamp Shares,
including those represented by a certificate(s) from which the legend has been
removed pursuant to Section 4(b) hereof, in compliance with applicable
prospectus delivery requirements, if any.

                  (f) REVERSE STOCK SPLIT. RGC agrees that it will vote in favor
of any proposal approved by a majority of the members of the board of directors
of E-Stamp seeking stockholder approval of a reverse stock split at any annual
or special meeting of the stockholders of E-Stamp held for such purpose prior to
the one hundred eightieth (180th) day following consummation of the Merger.


                                       8
<PAGE>

                  (g) SIDE LETTER. The parties agree that if, pursuant to the
terms of that certain letter agreement, dated of even date herewith, between the
Company and E-Stamp, the Merger is restructured to be an acquisition by the
Company of E-Stamp, the parties shall amend this Agreement and the E-Stamp
Registration Rights Agreement (provided that the economic and other benefits to
be afforded RGC pursuant to this Agreement and the E-Stamp Registration Rights
Agreement are preserved in their entirety in such amended agreements) and take
such other actions as are necessary to reflect the Company as the surviving
company in the Merger and to consummate the transactions contemplated by this
Agreement and the E-Stamp Registration Rights Agreement.

            5. CONDITIONS TO THE COMPANY'S AND E-STAMP'S OBLIGATIONS.

                  The obligations of the Company and E-Stamp hereunder to pay to
RGC $1,000,000 and issue the Company Shares in redemption of the Debenture at
the Closing is subject to the satisfaction, at or before the date of the

suit on such judgment or in any other lawful manner.

                  (c) COUNTERPARTS; SIGNATURES BY FACSIMILE. This Agreement may

agreements among the parties with respect to the matters covered herein or
therein. Except as specifically set forth in this Agreement, the E-Stamp
Registration Rights Agreement and the Waiver, none of the Company, E-Stamp or
