               -----------------------

               (a) Sears shall indemnify, defend and hold the Company and each
of its officers, directors and affiliates, including WAH immediately following
the Closing (each, a "Company Indemnitee"), harmless from and against, and shall
reimburse each Company Indemnitee for, any and all Losses (as defined below)
that may be incurred or suffered by such Company Indemnitee relating to, based
upon, resulting from or arising out of (i) any breach or other violation of any
representation, warranty, agreement, obligation or commitment of Sears under
this Agreement or the Assumption Agreement, (ii) any WAH Liabilities (as defined
below), (iii) the Share Exchange or Merger Transaction; provided, that Sears
will not indemnify the Company for any Losses that arise out of or result from
(w) the Company's breach or violation of any representation or warranty (without
regard to any materiality or knowledge qualifiers otherwise pertaining thereto),
agreement, obligation or commitment of the Company under this Agreement or the
Assumption Agreement, including any of the covenants contained in Section 1.6 of
this Agreement, (x) any liabilities which arise out of or result from any

Company or its subsidiaries that exists either as of or prior to the Closing
(the "Company Liabilities") or (y) any liabilities of WAH, contractual or
otherwise, that occur as a result of or arise from the Company Liabilities
through agreement, operation of law or otherwise or (iv) Sears' ownership of the
equity of WAH, except that any such Losses relating to, based upon, resulting
from or arising out of any breach or other violation of any representation and
warranty set forth in Section 3.8 or subject to indemnification under Section
5.2 shall be governed exclusively by Section 5. The parties hereto agree that
this Agreement, including the indemnification provisions hereof, shall not be
deemed to alter in any way Sears' liability under the Merger Agreement (as
defined in Schedule 3.6 hereto), except to the extent that Sears' liability
under the Merger Agreement will be sole rather than joint and several with WAH.

               (b) The Company shall indemnify, defend and hold Sears and each
of its officers, directors and affiliates (each, a "Sears Indemnitee"), harmless
from and against, and shall reimburse each Sears Indemnitee for, any and all
Losses that may be incurred or suffered by such Sears Indemnitee relating to,
based upon, resulting from or arising out of any breach or other violation of
any representation, warranty, agreement, obligation or commitment of the Company
under this Agreement or the Assumption Agreement, including any of the covenants
contained in Section 1.6 of this Agreement.

                -----------------
indemnification under any provision of Section 4.

                                       10

<PAGE>

               "Indemnifying Party" shall mean any Person against whom a claim
                ------------------
for indemnification is being asserted under any provision of Section 4.

               "Losses" shall mean any and all direct or indirect claims, suits,
                ------
actions, proceedings, liabilities, obligations, judgments, fines, penalties,
settlements, losses, damages, costs and expenses of any kind or nature
(including, without limitation, the reasonable fees and disbursements of outside
counsel, accountants and other experts whether incurred in connection with any
of the foregoing or in connection with any investigative, administrative or
adjudicative proceeding whether or not such Indemnified Party shall be
designated a party thereto), together with any and all reasonable costs and
actual out-of-pocket expenses associated with the investigation of the same.

               "WAH Liabilities" shall mean any and all liabilities,
                ---------------
obligations, duties, responsibilities and commitments, contractual or otherwise,
of WAH arising or resulting from or relating to any fact, event or circumstance
that existed or occurred at any time prior to the time of the consummation of
the Closing, whether or not described, referenced or listed in this Agreement
(including any Schedule hereto) or any Related Agreement and whether or not it
is known, should have been known or becomes known by the Company or any of its
officers, directors, employees, affiliates, agents or representatives, and shall
include, without limitation, any and all liabilities and obligations of WAH
arising out of or resulting from the Affidavit of Lost Stock Certificate dated
February 5, 2002, which was made by WAH to the Company with respect to
11,474,606 shares of Common Stock held by WAH.

          4.2 Indemnification Principles; Claims Against an Indemnified Party by
              -----------------------------------------------------------------
Third Parties. In the event of any claim for indemnification hereunder resulting
-------------
from or in connection with any claim, suit, arbitration or other legal
proceeding by a third party, the notice to the Indemnifying Party provided
pursuant to Section 4.3 shall specify the nature of and the basis for such
claim, together with the amount, or if then not reasonably determinable, the
estimated amount, determined in good faith, of the claim.

          4.3 Defense of Indemnified Party Against Claims by Third Parties. If
              ------------------------------------------------------------
any Indemnified Party shall receive notice of any third party claim, suit,
arbitration or other legal proceeding giving rise to indemnity under this
Agreement, the Indemnified Party shall give the Indemnifying Party written
notice in compliance with Section 4.2 of the same within fifteen (15) days of
the receipt by the Indemnified Party of such third party notice; provided,
however, that failure to provide such written notice shall not release the
Indemnifying Party from any of its obligations under this Section 4, except to
the extent (and only to the extent) the Indemnifying Party is materially
prejudiced by such failure. The Indemnifying Party may, upon prompt written
notice furnished to the Indemnified Party, assume the defense of any such claim,
suit, arbitration or other proceeding, with counsel reasonably satisfactory to
the Indemnified Party, if the Indemnifying Party acknowledges to the Indemnified
Party in writing its obligations to indemnify the Indemnified Party with respect
to all elements of such claim. If the Indemnified Party furnishes such written
acknowledgment, the Indemnifying Party will be entitled to assume and control
the defense of such claim, suit, arbitration or other legal proceeding, and the
Indemnified

                                       11

<PAGE>

Party shall be entitled to participate in (but not control) the defense of any
such action, with its own counsel and at its own expense. If the Indemnifying
Party does not assume the defense of any such claim, suit, arbitration or other
legal proceeding as provided above, (i) the Indemnified Party may defend against
the same, in such manner as it may reasonably deem appropriate and at the
Indemnifying Party's cost and expense, including, without limitation, settling
such claim, arbitration or other proceeding, after giving notice of the same to
the Indemnifying Party (which settlement shall only be with the written consent
of the Indemnifying Party, which consent shall not be unreasonably withheld)
and (ii) the Indemnifying Party shall be entitled to participate in (but not
control) the defense of such action, with its own counsel and at its own
expense. If the Indemnifying Party thereafter seeks to question the manner in
which the Indemnified Party defended such claim, suit, arbitration or other
proceeding, the Indemnifying Party shall have the burden of proving by a
preponderance of the evidence that the Indemnified Party did not defend such
third party claim in a reasonably prudent manner. No Indemnifying Party may
seek to question the amount or nature of any settlement entered into or made by
any Indemnified Party in accordance with this Section 4.3 if such settlement
was consented to or approved by the Indemnifying Party in writing.

          4.4 Claims Against an Indemnifying Party by an Indemnified Party. In
              ------------------------------------------------------------
the event any Indemnified Party should have a claim under this Section 4 against
any Indemnifying Party that does not involve a claim by a third party, the
Indemnified Party shall deliver written notice with reasonable promptness
specifying the nature of and the basis for such claim, together with the amount,
or if not then reasonably determinable, the estimated amount, determined in good
faith, of the Losses arising from such claim to the Indemnifying Party;
provided, however, that failure to provide such written notice shall not release
the Indemnifying Party from any of its obligations under this Section 4, except
to the extent (and only to the extent) the Indemnifying Party is materially
prejudiced by such failure. If the Indemnifying Party notifies the Indemnified
Party that it does not dispute the claim described in such notice, the Losses
arising from the claim specified in the notice will be conclusively deemed a
liability of the Indemnified Party and the Indemnifying Party shall pay the
amount of the Losses to the Indemnified Party on demand following the final
determination thereof. If the Indemnifying Party fails to notify the Indemnified
Party, such failure to be deemed a dispute of the claim, then the Indemnifying
Party and the Indemnified Party will proceed in good faith to negotiate a
resolution of such dispute, and if not resolved through negotiations, such
dispute may, if desired by the Indemnified Party, be resolved by litigation in a
court of competent jurisdiction.

          4.5 Insurance Offset. If the amount of any indemnifiable Losses, at
              ----------------
any time following the payment of an indemnified obligation, is offset or
reduced by the payment of any insurance proceeds, the amount of such insurance
proceeds, less any costs, expenses, premiums or taxes incurred in connection
therewith (including, but not limited to, any future increase in insurance
premiums, retroactive premiums, costs associated with any loss of insurance and
replacement thereof or self-insured component of such insurance coverage) will
promptly be repaid to the Indemnifying Party.

                                       12

<PAGE>

          4.6  Survival of Obligation. The covenants contained in this Agreement
               ----------------------
shall survive the Closing without limitation, and the indemnification agreements
contained in this Agreement shall survive for so long as their underlying claims
survive. The representations and warranties contained in this Agreement (i)
shall survive the Closing without limitation except to the extent there is an
applicable statute of limitations, in which case, each such representation and
warranty shall survive until the ninetieth (90th) day following the expiration
of such statute of limitation (taking into account any extensions thereof) and
(ii) shall in no way be affected by any investigation made by or on behalf of or
knowledge of the subject matter thereof by the Company or Sears or any of their
officers, directors, employees, affiliates, representatives or agents.
Notwithstanding anything in this Section 4.6 to the contrary, as to any breach
of any representation or warranty with respect to which a claim is submitted in
accordance with the terms of this Agreement and within the time periods
permitted by the immediately preceding sentence, (i) such claim may only be made
with respect to an event that occurred prior to the expiration of the applicable
statute of limitations, (ii) subject to the preceding clause (i), such
representation and warranty shall survive until the claim is resolved and (iii)
in any event, each Indemnified Party shall be entitled to be indemnified by the
Indemnifying Party for any costs and expenses (including the reasonable fees and
disbursements of outside counsel) it incurs in asserting the statute of
limitations as a defense to any claim (for which it would otherwise be entitled
to indemnification under this Agreement but for the expiration of such statute
of limitations) being brought against such Indemnified Party.

                                    SECTION 5
                                   TAX MATTERS

required to be filed by or on behalf of any consolidated, combined, unitary or
other group in which WAH was or is a member, including, but not limited to, the

               "Governmental Authority" shall mean any nation or government, any

legislative, judicial, regulatory or administrative functions of or pertaining
to government, including, without limitation, any governmental authority,

organization.

               "Other WAH Tax Returns" shall mean all material Tax Returns other
                ---------------------
than the Consolidated WAH Tax Returns required to be filed by or on behalf of
WAH.

                                       13

<PAGE>

               "Person" shall mean any corporation, partnership, limited
                ------
liability company, trust, individual, unincorporated organization or a

require.

               "Tax Return" shall mean any return, report, information return,
                ----------
registration form or other document (including any related or supporting
information) related to the obligations of any Person filed or required to be
filed with any taxing authority in connection with the determination of any Tax
or the administration of any laws, regulations or administrative requirements
relating to any Tax.

               "Taxes" means any income, alternative or add-on minimum tax,

whatsoever, addition to tax or additional amount related to the obligations of
any Person, imposed by any Governmental Authority responsible for the imposition
of any such tax (domestic or foreign), together with any interest and any
penalty thereon.

          5.2  Tax Indemnification. Sears shall be liable for, shall pay or
               -------------------
cause to be paid and shall indemnify and hold the Company Indemnitees (as
defined in Section 4.1(a)) harmless from and against any and all Taxes and other
Losses, if any, arising out of or based upon or for or in respect of each of the
following: (i) any and all Taxes with respect to WAH for any and all taxable
periods (including any and all Taxes arising on and after the Closing, including
any Taxes arising out of the Share Exchange and any Taxes arising out of the
Merger Transaction); (ii) any and all Taxes resulting solely from WAH having
been included in the Consolidated WAH Tax Returns or any other consolidated,
combined, unitary or other group Tax Return that included WAH for any taxable
period (or portion thereof) pursuant to Treasury Regulation Section 1.1502-6(a)
or any analogous or similar state, local or foreign law or regulations (other
than any liability arising under such Treasury Regulation or analogous law by
reason of WAH being a member of the consolidated, combined, unitary or other

other group Tax Return that includes WAH and the Company, and the Merger
Transaction; and (iv) any breach of a representation and warranty set forth in
Section 3.8. of this Agreement. If the Company shall breach its covenant under
Section 1.6 of this Agreement, then Sears' liabilities under this Section 5.2
shall be determined as if such breach had not occurred.

          5.3  Preparation of Tax Returns; Payment of Taxes.
               --------------------------------------------

               (a) Sears shall prepare or cause to be prepared and file or cause
to be filed all Consolidated WAH Tax Returns and all material Other WAH Tax
Returns which are required to be filed for all periods except for Tax Returns in
which WAH is part of a

                                       14

<PAGE>

consolidated, combined, unitary, or other group including the Company. Sears
shall pay the amount of any Taxes shown to be due thereon to the appropriate
Governmental Authority.  Upon written request by the Company, Sears shall
provide the Company with (i)(A) a written statement that all Consolidated WAH
Tax Returns have been filed, and all Taxes shown as due thereon have been paid
and (B) portions of such Consolidated WAH Tax Returns showing any of the WAH
activities and (ii) copies of all Other WAH Tax Returns and copies of checks
for any payment of Taxes shown as due thereon.

              (b) For federal income Tax purposes, the taxable year of WAH ends
as of the close of the Closing Date and, with respect to all other Taxes, Sears
and the Company will, unless prohibited by applicable law, close the taxable
period of WAH as of the close of the Closing Date. Neither Sears nor the Company
shall take any position inconsistent with the preceding sentence on any Tax
Return.

              (c) Sears shall be responsible for filing any amended
Consolidated WAH Tax Returns that are required as a result of examination
adjustments made by the Internal Revenue Service or by the applicable state,
local or foreign taxing authorities for such taxable years as finally
determined. Any required amended Other WAH Tax Returns resulting from such
examination adjustments, as finally determined, shall be prepared by Sears and
furnished to the Company for approval (which approval shall not be unreasonable
withheld), signature (if necessary) and filing at least 30 days prior to the due
date for filing such amended returns.

          5.4 Tax Proceedings. In the event of a contest with a taxing authority
              ---------------
over Taxes for which Sears is liable pursuant to Section 5.2 or the treatment of
an indemnity payment under Section 5.5(b), the Company shall deliver written
notice with reasonable promptness specifying the nature of and the basis for
such contest, together with the amount, or if not then reasonably determinable,
the estimated amount, determined in good faith, of the amount in dispute to
Sears; provided, however, that the failure to provide such written notice shall
not release Sears from any of its obligations under this Section 5, except to
the extent (and only to the extent) Sears is materially prejudiced by such
failure. Sears will be entitled to control, at its expense, the proceedings with
respect to such Taxes, but only if Sears submits to the Company an executed
acknowledgment that it is liable for all Taxes (including interest and
penalties) resulting from such contest. Notwithstanding the preceding sentence,
the Company will in any event be entitled to control the proceedings which
relate to a consolidated, combined, unitary or other group Tax Return filed by
the Company and its subsidiaries, as the case may be. If the Company is not
entitled to control the proceedings under the foregoing provisions, Sears will
provide, or cause to be provided, to the Company copies of all correspondence
received from the taxing authority in connection with such proceedings. The
party in control of the proceeding under this Section 5.4 shall not enter into
any agreement or compromise or settlement of such contest that could affect a
period that is the responsibility of the non-controlling party without the
written consent of the non-controlling party (which consent shall not be
unreasonably withheld). The party which is not entitled to control any such
proceeding shall be afforded a reasonable opportunity to participate in the
defense thereof at its own expense and shall reimburse the party

                                       15

<PAGE>

entitled to control such proceedings for any additional expenses incurred by
such controlling party as a result of the non-controlling party's participation
in such proceeding.

                                       16

<PAGE>

          5.5 Payment of Indemnification.
              --------------------------

              (a) If a claim shall be made by any taxing authority, which, if
successful, might result in an indemnity payment to the Company pursuant to
Section 5.2, the Company shall promptly notify Sears in writing of such claim (a
"Tax Claim"). If notice of a Tax Claim is not given to Sears within a sufficient
period of time to allow Sears to effectively contest such Tax Claim, or in
reasonable detail to apprise Sears of the nature of the Tax Claim, in each case
taking into account the facts and circumstances with respect to such Tax Claim,
Sears shall not be liable to the Company, to the extent that Sears' position is
actually prejudiced as a result thereof. Upon payment of any Taxes with respect
to which a party is entitled to receive indemnification hereunder, such party
shall submit an invoice to the indemnifying party stating that such Taxes have
been paid and giving in reasonable detail the particulars relating thereto. The
indemnifying party shall remit payment for such Taxes promptly upon receipt of
such invoice.

              (b) Any payment for indemnification hereunder (whether under
Section 4 or Section 5) shall be treated for federal income tax purposes as
payments to which Section 118 of the Code applies. To the extent that such
treatment is ultimately determined to be inapplicable and that an
indemnification payment is in whole or in part taxable to any Company
Indemnitee, then any such indemnification payment shall be "grossed up" to take
into account any Taxes imposed upon such Company Indemnitee with respect to such
indemnification payment so that the net "after-tax" amount of such payment is
sufficient to satisfy the Taxes, Losses, WAH Liabilities or other indemnified
amounts under Section 4 and Section 5; provided, however, that any such gross up
shall take into account Section 4.5 of this Agreement and the tax effect to the
Indemnified Party of the amounts so indemnified.

          5.6 Assistance and Cooperation. After the Closing Date, each of Sears
              --------------------------
and the Company shall:

              (a) assist (and cause its respective affiliates to assist) the
other party in preparing any Tax Returns which such other party is responsible
for preparing and filing in accordance with Section 5.3 hereof;

              (b) cooperate fully in preparing for any audits of, or disputes,
contests or proceedings with, taxing authorities regarding any Tax Returns which
relate to WAH;

              (c) make available to the other and to any taxing authority as
reasonably requested all information, records and documents relating to Tax
liabilities which are attributable to WAH;

              (d) preserve all such information, records and documents until the
expiration of any applicable statutes of limitations or extensions thereof and
as otherwise required by law;

                                       17

<PAGE>

               (e) make available to the other, as reasonably requested,
personnel responsible for preparing or maintaining information, records and
documents in connection with Tax matters;

               (f) provide timely notice to the other in writing upon receipt of
notice of any pending or threatened Tax audits or assessments relating to WAH
for any period;

               (g) furnish the other with copies of all correspondence received
from any taxing authority in connection with any Tax audit or information
request with respect to any period;

               (h) keep confidential any information obtained pursuant to this
Section 5.6, except as may otherwise be necessary in connection with the filing
of Tax Returns or claims for refund or in conducting any audit or other Tax
proceeding; and

               (i) furnish the other with adequate information which would
enable the other party to determine its entitlement to, and the amount of, any
refund or credit to which either party reasonably believes the other party may
be entitled.

          5.7  Tax Sharing Agreements. All Tax sharing and similar agreements
               ----------------------
(other than the provisions of this Agreement) between WAH and Sears or any other
Person shall be terminated as of the Closing Date, and WAH shall have no
liability from and after the Closing Date under any such agreement.

          5.8  Survival of Obligations. The obligations of the parties set forth
               -----------------------
in this Section 5 shall be governed by Section 4.6 of this Agreement.

          5.9  Treatment of the Exchange and Merger Transaction. Sears and the
               ------------------------------------------------
Company shall treat this Agreement as a Plan of Reorganization under Section 368
of the Code and comparable provisions of state and local Tax law.

          5.10 Provisions of this Section to Control. In the event of a conflict
               -------------------------------------
between the provisions of this Section 5 and any other provisions of this
Agreement, the provisions of this Section 5 shall control.

                                    SECTION 6
                                  MISCELLANEOUS

          6.1  Governing Law. This Agreement shall be governed by and
               -------------
interpreted under the laws of the State of Delaware, without giving effect to
principles of conflicts of laws.

          6.2  Expenses. Prior to the Closing, (i) the Company shall inform
               --------
Sears in writing of the aggregate amount of expenses the Company shall have
incurred or good faith

                                       18

<PAGE>

estimates that it will incur in connection with this Agreement and the
consummation of the transactions contemplated hereunder and (ii) Sears shall
have contributed an equal amount of cash to an account held by WAH.

          6.3  Transfer Taxes. Sears shall be liable for and shall pay all
               --------------
excise, sales, use, transfer (including real property transfer or gains), stamp,
documentary, filing, recordation and other similar Taxes which may be imposed in
connection with the transactions contemplated by this Agreement, together with
any interest, additions or penalties with respect thereto ("Transfer Taxes").
Each party hereto hereby agrees to file all necessary documentation in
connection with the payment and reporting of Transfer Taxes.

          6.4  Further Assurances. At any time or from time to time after the
               ------------------
Closing, the Company and Sears agree to cooperate with each other, and at the
request of the other party, to execute and deliver any further instruments or
documents and to take all such further action as the other party may reasonably
request in order to evidence or effectuate the consummation of the transactions
contemplated hereby and to otherwise carry out the intent of the parties
hereunder.

          6.5  Successors and Assigns. Neither this Agreement nor any right,
               ----------------------
interest or obligation hereunder may be assigned by any party hereto without the
prior written consent of the other party hereto and any attempt to do so will be
void, except for (a) assignments and transfers by operation of law and (b) the
Company or Sears may assign any or all of their respective rights, interests and
obligations hereunder to an Affiliate, provided that any such Affiliate agrees
in writing to be bound by all of the terms and conditions and provisions
contained herein, but no such assignment referred to in clause (b) shall relieve
the Company or Sears of their respective obligations hereunder. Subject to the
preceding sentence, this Agreement is binding upon, inures to the benefit of and
is enforceable by the parties hereto and their respective successors and
assigns.

          For purposes of this Section 6.5, "Affiliate" means any Person that

controlled by or is under common control with the Person specified. For purposes
of the definition of "Affiliate," control of a Person means the power, direct or
indirect, to direct or cause the direction of the management and policies of
such Person whether by contract or otherwise and, in any event and without
limitation of the previous sentence, any Person owning ten percent (10%) or more
of the voting securities of another Person shall be deemed to control that
Person.

          6.6  No Third Party Beneficiaries. The terms and provisions of this
               ----------------------------
Agreement are intended solely for the benefit of each party hereto and their
respective successors or permitted assigns, and it is not the intention of the

         B.  Bank is willing to waive such defaults and restructure Borrower's

AGREEMENTS BETWEEN BORROWER AND BANK INCLUDING, BUT NOT LIMITED TO, THE LOAN
DOCUMENTS, NOT SPECIFICALLY MODIFIED HEREIN, SHALL REMAIN IN FULL FORCE AND
EFFECT IN ACCORDANCE WITH THEIR ORIGINAL TERMS.

                                    AGREEMENT
                                    ---------

         NOW, THEREFORE, in consideration of (i) the above recitals and the

Agreement and all documents, instruments and agreements required to be executed
in accordance with this Agreement; (iii) the satisfaction of all Conditions

         A.  The Credit Agreement and Other Loan Documents.
             ---------------------------------------------

             1. On or about April 12, 2000, Borrower and Bank entered into that
         certain Credit Agreement (as amended, restated, modified, supplemented
         or revised from time to time, the "Credit Agreement"), pursuant to
         which Borrower promised to pay Bank the principal amount of up to Ten
         Million Dollars ($10,000,000.00), together with interest on the funds

                                       -1-

<PAGE>

         disbursed thereunder at the rate provided for in the promissory notes
         described below. The Credit Agreement was amended pursuant to a First
         Amendment to Credit Agreement dated as of April 18, 2000 ("First
         Amendment"), and by a Second Amendment to Credit Agreement dated as of
         November 14, 2000 ("Second Amendment").

                2. Pursuant to the Credit Agreement, Borrower executed and
         delivered to Bank a (a) Promissory Note in the principal amount of Six
         Million Dollars ($6,000,000.00) (as amended, restated, modified,
         supplemented or revised from time to time, the "Term Note") and a (b)
         Revolving Note in the principal amount of Four Million Dollars
         ($4,000,000.00) (as amended, restated, modified, supplemented or
         revised from time to time, the "Revolving Note"). Pursuant to the
         Second Amendment, Borrower executed and delivered to Bank a new Term
         Note in the principal amount of Six Million Three Hundred Thousand
         Dollars ($6,300,000.00) (The Term Note and Revolving Note, as amended,
         restated, modified, supplemented or revised from time to time, are
         referred to herein collectively as the "Notes").

                3. Also pursuant to the Credit Agreement: (a) Borrower executed
         and delivered to Bank: (i) that certain Commercial Security Agreement
         dated as of April 12, 2000 (as amended, restated, modified,
         supplemented or revised from time to time, the "Commercial Security
         Agreement"); (ii) that certain Commercial Pledge and Security Agreement
         dated as of April 12, 2000 (as amended, restated, modified,
         supplemented or revised from time to time, the "Commercial Pledge
         Agreement"); (iii) that certain Patent Security Agreement dated as of
         April 12, 2000 (as amended, restated, modified, supplemented or revised
         from time to time, the "Patent Security Agreement"); and (iv) that
         certain Trademark Security Agreement dated as of April 12, 2000 (as
         amended, restated, modified, supplemented or revised from time to time,
         the "Trademark Security Agreement"); and (b) W3Commerce LLC, a Delaware
         limited liability company, executed and delivered to Bank a Commercial
         Security Agreement dated as of April 12, 2000 (as amended, restated,
         modified, supplemented or revised from time to time, the "W3C
         Commercial Security Agreement"). The Credit Agreement, Commercial
         Security Agreement, Commercial Pledge Agreement, Patent Security
         Agreement, Trademark Security Agreement and W3C Commercial Security
         Agreement each grant Bank a valid, perfected, first priority security
         interest in the property described therein as collateral (the
         "Collateral") securing the Borrower's obligations to Bank under the
         Loan Documents.

                4. On or about April 12, 2000, Borrower executed and delivered
         to Bank two form UCC-1 financing statements. Bank filed the financing
         statements with the office of the Secretary of State of California.
         Bank has filed the Patent Security Agreement and the Trademark Security
         Agreement with the United States Patent and Trademark Office.

                5. Borrower has delivered to Bank a warrant to purchase stock
         dated December 1, 2000 granting to Bank stock warrants in Borrower for
         a total of 250,000 shares of Borrower's Common Stock, on terms and
         conditions more fully set forth therein.

                6. The documents referenced above and all documents, security
         agreements and written amendments, notes and so forth related thereto
         are hereinafter collectively referred to as "Loan Documents." Upon
         execution and delivery of the Amended Promissory Note (defined below),
         it shall be deemed one of the Loan Documents. All capitalized terms not
         defined herein shall have the meaning described in the Loan Documents.

                                       -2-

<PAGE>

              7. The Borrower acknowledges that the Loan Documents constitute
         duly authorized, valid, binding, fully perfected and continuing
         agreements and obligations of Borrower to Bank, enforceable in
         accordance with their respective terms; and that Borrower has no
         claims, cross-claims, counterclaims, setoffs or defenses of any kind or
         nature which would in any way reduce or offset its obligations to Bank
         under the Loan Documents as of the date of this Agreement.

         B.   Existing Indebtedness. Borrower acknowledges and agrees that the
              ---------------------
current outstanding principal balance owed to Bank under the Loan Documents is
Seven Million One Hundred and Thirty-two Thousand Dollars ($7,132,000.00) (the
"Existing Principal Amount"). The amount owed under the Loan Documents includes
the Existing Principal Amount, plus interest accrued thereon from December 31,
2001 to January 25, 2002 in the amount of Thirty-Four Thousand Four Hundred
Seventy-One and 33/100s Dollars ($34,471.33), together with the Bank's costs,
expenses and reasonable attorneys' fees (collectively, the "Existing
Indebtedness"). The Existing Principal Amount shall be evidenced by the Amended
Promissory Note (defined below). All attorneys' fees and costs incurred by Bank
through and including January 25, 2002, in an amount not exceeding One Hundred
Sixty Thousand Dollars ($160,000.00), and all interest accrued to January 25,
2002, shall be paid by Borrower upon execution of this Agreement.

         C.   Defaults Under Credit Agreement and Other Loan Documents;
              ---------------------------------------------------------
Remedies.
--------
Borrower acknowledges and agrees that Borrower is in default under the terms and
conditions of the Loan Documents in that, inter alia, Borrower failed to:
                                          ----- ----
maintain compliance with financial covenants and to eliminate over advances
(collectively, the "Defaults"). Borrower acknowledges and agrees that but for
this Agreement, the Bank is fully entitled to exercise all of its rights and
remedies under the Loan Documents, including but not limited to foreclosing on
its Collateral. Borrower has no defense at law or equity, including the right of
setoff, to the Bank's claims for repayment of the Existing Indebtedness.

         II.  Limited Scope of Agreement. Nothing contained in this Agreement
              --------------------------
shall be interpreted as or be deemed a release or a waiver by Bank of any of the
terms and conditions of the Loan Documents, or any other documents, instruments
and agreements between the parties hereto except as specifically provided in
this Agreement. Unless specifically modified herein, all other terms and
provisions of the Loan Documents shall remain in full force and effect in
accordance with their original terms, and are hereby ratified and confirmed in
all respects. This Agreement does not constitute a waiver or release by Bank of
any obligations between Borrower and Bank, or a waiver by Bank of any defaults
by Borrower under the Loan Documents, unless expressly so provided herein, nor
between Bank and any other person or entity. The Bank has no duty to advance any
funds under the Loan Documents.

         III. Waiver of Defaults.  Subject to, and effective upon, satisfaction
              ------------------
of the Conditions Precedent set forth in section VIII. hereof:

         A.   Bank hereby waives all past defaults, including without limitation
those described in Section I.C. of this Agreement.

         B.   Borrower acknowledges and agrees that Bank's waiver of Defaults
set forth immediately above concerns only Borrower's Defaults identified in

("Existing Defaults"), but not as to any defaults

                                       -3-

which may arise in the future, or which are unknown to Bank, or which are not
specified in Section I.C. hereof.

         IV.  Amendments to Credit Agreement and Other Loan Documents. Subject

         A.   Section 1.01 of the Credit Agreement specifying the Term Loan

         attached hereto as Exhibit A (the "Amended Promissory Note"). The
         principal amount of the Amended Promissory Note shall be equal to the
         Existing Principal Amount. The interest rate, maturity date and other

         which Borrower's EBITDA for the year 2002 exceeds the sum of Four
         Million Dollars ($4,000,000.00). Such additional principal payment
         shall be made by the earlier of March 31, 2003 or the date Borrower
         files its audited financial statements with the United States
         Securities and Exchange Commission. For purposes of this provision,

Agreement concerning certain reporting requirements and financial covenants are
hereby deleted in their entirety.

         E.   Section 4.16 of the Credit Agreement concerning asset sales is

         Bank shall apply such net cash proceeds first toward the remaining
         principal reductions due under the Amended Promissory Note in inverse
         order of maturity; provided, however, that upon the occurrence of an
         Event of Default, Bank shall have the right to apply such net cash
         proceeds in its sole and absolute discretion.

         F.   Section 5.05 of the Credit Agreement is amended by adding the
following to the existing text:

                                       -4-

         exchange for cash consideration not less than Two Million Eight Hundred
         Thousand Dollars ($2,800,000.00).

         H.   Section 5.08 of the Credit Agreement is amended by adding the
following to the existing text:

         Notwithstanding the foregoing, nothing in this Agreement shall prohibit
         Borrower from paying dividends on preferred stock held by Redwood;
         provided, however, that no such dividends shall be paid while there is
         an Event of Default under this Agreement or any condition, act or event
         which, with the passage of time or the giving of notice or both would
         constitute an Event of Default under this Agreement; and further
         provided, however, that the maximum amount of such dividends that may
         be paid in any calendar quarter shall not exceed the sum of
         $240,000.00.

affiliates fees for management services in a total amount not exceeding
$15,000.00 (collectively) per month, or such greater amount as Bank shall agree
in writing, in its sole and absolute discretion; provided, however, Borrower
shall not pay any amounts to Redwood and/or its affiliates for management
services while there is an Event of Default under this Agreement or any
condition, act or event which, with the passage of time or the giving of notice
or both would constitute an Event of Default under this Agreement.

         D.   Borrower hereby authorizes Bank to collect all amounts due Bank
under any of the Loan Documents by charging Borrower's accounts at Bank.

                                       -5-

specified in this paragraph shall not in any way be construed as a warranty or
representation that Bank's attorneys' fees and other costs incurred in preparing

Thousand Five Hundred Dollars ($2,500.00).

         VII.  Affirmative Covenants.

               written notification of any such change;

         X.   Representations and Waivers Concerning Release Provisions.
              ---------------------------------------------------------

         Borrower understands and has been advised by its legal counsel of the
provisions of Section 1542 of the California Civil Code, which provides as
follows:

            A general release does not extend to claims which the creditor does
            not know or suspect to exist in his favor at the time of executing
            the release, which if known by him must have materially affected his
            settlement with the debtor.

Borrower understands and hereby waives the provisions of California Civil Code
Section 1542 and declares that it realizes it may have damages Borrower
presently knows nothing about and that, as to them, Bank has been released
pursuant to these release provisions. Borrower also declares that it understands
that Bank would not agree to enter into this Agreement if the release provisions
set forth above did not cover damages and their results which may not yet have
manifested themselves or may be unknown to or not anticipated at the present
time by Borrower.

         Borrower represents and warrants that Borrower is the owner of the
claims hereby compromised and that Borrower has not heretofore assigned or
transferred, nor purported to assign or transfer, to any person or entity
("Person") any of the Released Matters. Borrower further agrees to indemnify and
hold harmless Bank from all liabilities, claims, demands, damages, costs,
expenses, and attorneys' fees incurred by Bank as the result of any Person
asserting any such assignment or transfer of any rights or claims.

         XI.  Events of Default. In addition to any other Events of Default set
              -----------------
forth in this Agreement or the Loan Documents, an "Event of Default" shall exist
under this Agreement and under the Loan Documents if any one or more of the
following events occur:

         A.   All of the Conditions Precedent set forth in Section VIII. hereof
are not fully satisfied or waived, each in Bank's sole and absolute discretion,
on or before January 25, 2002; or

         B.   Borrower shall fail to pay any payment as provided herein within
five (5) days of its due date; or

         C.   Any representation or warranty made under or in connection with
this Agreement, or any certificate or statement furnished or made to Bank
pursuant thereto, shall prove to be untrue or misleading in any material respect
as of the date on which such representation or warranty is made; or

         D.   Borrower shall take any action to the effect that, or make any
claim that any Loan Document, including without limitation this Agreement,
is/are not legal, valid, binding agreements enforceable against any party

inoperative the same; or shall in any way whatsoever cease to give or provide
the respective liens, security interests, rights, titles, interests, remedies,
powers or privileges intended to be created thereby; or

         E.   A default, other than the Existing Defaults, shall occur in the
performance of any material term, condition, covenant or agreement contained in
the Loan Documents, in this Agreement, or in connection with any other
obligation owing by Borrower to Bank; or

                                       -8-

judgment or decree shall be entered by any court of competent jurisdiction or
other competent authority approving a petition seeking reorganization of
Borrower; (ii) an order shall be entered by any court of competent jurisdiction
or other competent authority appointing a receiver, custodian, trustee,
intervenor or liquidator for Borrower as to all or substantially all of its
assets, and such order, judgment or decree shall continue un-stayed and in
effect for a period of sixty (60) days; or (iii) an involuntary petition seeking
bankruptcy, reorganization or receivership shall be filed against Borrower which
is not dismissed within sixty (60) days of the filing thereof; or (iv) an event

     XII. Remedies.
          --------

     A. If an Event of Default shall occur under this Agreement, any other Loan
Document, or any other agreement referenced herein or executed in connection
herewith, Bank may exercise, at its election, and without notice, demand,
protest or presentment (which notice, demand, protest and presentment are
expressly waived) in addition to all rights and remedies granted to it in the
Loan Documents, any or all of the following (failure to specify any remedy
herein shall not limit Bank's remedies, nor be deemed to create a conflict or
contradiction with the Loan Documents):

          1. Bank may exercise all of its rights and remedies and may declare
     all amounts owed under the Loan Documents immediately due and payable;

          2. Bank may proceed to enforce the Loan Documents and this Agreement
     and exercise any or all of the rights and remedies afforded to Bank by the
     California Commercial Code, the California Civil Code, the California Code
     of Civil Procedure or otherwise possessed by Bank;

          3. Bank may, to the fullest extent permitted by law: (1) sell its
     Collateral or any interest therein at public or private sale for cash or
     upon credit and for immediate or future delivery and for such price and on
     such terms as Bank shall deem appropriate, and negotiate, endorse, assign,
     transfer and deliver to the purchaser or purchasers thereof (which may be
     Bank) the Collateral so sold, and each purchaser at any sale shall hold the
     property sold absolutely free from any claim or right on the part of
     Borrower (and Borrower hereby waives, to the extent permitted by law, all
     rights of redemption, stay and/or appraisal which Borrower now has or may
     at any time in the future have); and/or

                                       -9-

<PAGE>

      (2) obtain specific performance by Borrower of any covenant or undertaking
      of Borrower in the Loan Documents herein; and/or (3) without notice to
      Borrower, proceed by suit or suits at law or in equity to foreclose its
      security interest and sell its Collateral or any portion thereof pursuant
      to judgment or decree of a court, courts or referee having competent
      jurisdiction; and/or (4) without notice to Borrower, exercise any of its
      rights under, or foreclose its Collateral thereunder;

          4. Without regard to the adequacy of Bank's Collateral, or to the
      solvency of Borrower, Bank may institute legal proceedings for the
      appointment of a receiver or receivers with respect to any or all of its
      Collateral pending foreclosure hereunder or for the sale of any or all of
      its Collateral under the order of a court of competent jurisdiction or
      under other legal process;

          5. Either personally, or by means of a court-appointed receiver, Bank
      may enter onto the premises where its Collateral is located and take
      possession of all or any of its Collateral and exclude therefrom Borrower
      and all others claiming under Borrower, and perform any acts necessary or
      appropriate to care for, maintain, preserve and protect its Collateral. In
      the event Bank demands or attempts to take possession of its Collateral in
      the exercise of any rights hereunder, Borrower promises and agrees to turn
      over promptly and to deliver complete possession thereof to Bank;

          6. Without notice to or demand upon Borrower, Bank may make such
      payments and do such acts as Bank may deem necessary to protect its
      security interest in its Collateral including, without limitation, paying,
      purchasing, contesting or compromising any encumbrance, charge or lien
      which is prior to or superior to the security interests granted in the
      Loan Documents and, in exercising any such powers or authority, to pay all
      expenses incurred in connection therewith; and/or

          7. Enforce any of the rights and remedies available to it under the
      Loan Documents or this Agreement, or according to applicable law.

      B.  All rights and remedies granted to Bank hereunder are cumulative, and
Bank shall have the right to exercise any one or more of such rights and
remedies alternatively, successively or concurrently as Bank may, in its sole
and absolute discretion, deem advisable.

      XIII. Revival Clause; Solvency.
            ------------------------

      If the incurring of any debt or the payment of money or transfer of
property made to Bank by or on behalf of Borrower should for any reason
subsequently be declared to be "fraudulent" or "preferential" within the meaning
of any state or federal law relating to creditor's rights, including, without
limitation, fraudulent conveyances, preferences or otherwise voidable or
recoverable payments of money or transfers of property, in whole or in part, for
any reason (collectively, "Voidable Transfers") under the Bankruptcy Code or any
other federal or state law, and Bank is required to repay or restore any such
Voidable Transfer or the amount or any portion thereof, or upon the advice of
its in-house counsel or outside counsel is advised to do so, then, as to such
Voidable Transfer or the amount repaid or restored (including all reasonable
costs, expenses and attorneys' fees of Bank related thereto), the liability of
Borrower under the Credit Agreement and Loan Documents, and all of Bank's rights
and remedies under the Credit

                                      -10-

<PAGE>

Agreement and Loan Documents, shall automatically be revived, reinstated and
restored and shall exist as though such Voidable Transfer had never been made to
the extent of any harm to Bank.

         Borrower represents and warrants that the execution, delivery and
performance of this Agreement will not (i) render Borrower insolvent as that
term is defined below; (ii) leave Borrower with remaining assets which
constitute unreasonably small capital given the nature of Borrower's business;
or (iii) result in the incurrence of Debts (as defined below) beyond Borrower's
ability to pay them when and as they mature and become due and payable. For the
purposes of this paragraph, "Insolvent" means that the present fair salable
value of assets is less than the amount that will be required to pay the
probable liability on existing Debts as they become absolute and matured. For
the purposes of this paragraph, "Debts" includes any legal liability for
indebtedness, whether matured or unmatured, liquidated or unliquidated,
absolute, fixed or contingent. Borrower hereby acknowledges and warrants that it
has derived or expects to derive a financial or other benefit or advantage from
this Agreement.
