 The Class B(2003-4) Notes 
  
 Section 2.01. Creation and Designation. There is hereby created a tranche of Card Series Class B Notes to be issued pursuant to the Indenture, the
Asset Pool 1 Supplement and the Indenture Supplement to be known as the “Card Series Class B(2003-4) Notes.” 
  
 Section 2.02. Adjustments to Required Subordinated Percentages. 
  
 (a) On any date, the Issuer may increase the Required Subordinated Percentage of Class C Notes or the Required Subordinated
Percentage of Class D Notes, in each case, for the Class B(2003-4) Notes without the consent of any Noteholders or the Note Rating Agencies. 
  
 (b) On any date, the Issuer may reduce the Required Subordinated Percentage of Class C Notes or the Required Subordinated Percentage of Class D Notes, in
each case for the Class B(2003-4) Notes, provided that the Issuer has (i) received written confirmation from each Note Rating Agency that has rated any Outstanding Notes of the Card Series that the change in such percentage will not result in a
Ratings Effect with respect to any Outstanding Class B(2003-4) Notes and (ii) delivered to the Indenture Trustee and the Note Rating Agencies a Master Trust Tax Opinion for each Master Trust and an Issuer Tax Opinion. 
  
 Section 2.03. Interest Payment. 
  
 (a) For each Interest Payment Date, the amount of interest due with respect
to the Class B(2003-4) Notes shall be an amount equal to the product of (i)(A) a fraction, the numerator of which is the actual number of days in the related Interest Period and the denominator of which is 360, times (B) the Note Interest
Rate in effect with respect to the related Interest Period, times (ii) the Outstanding Dollar Principal Amount of the Class B(2003-4) Notes determined as of the Record Date preceding the related Distribution Date. Any interest on the Class
B(2003-4) Notes will be calculated on the basis of the actual number of days in the related Interest Period and a 360-day year. 
  
 (b) Pursuant to Section 3.03 of the Indenture Supplement, on each Distribution Date, the Indenture Trustee shall deposit into the Class B(2003-4)
Interest Funding sub-Account the portion of Card Series Finance Charge Amounts allocable to the Class B(2003-4) Notes. 
  
 Section 2.04. Calculation Agent; Determination of LIBOR. 
  

(a) The Issuer hereby agrees that for so long as any Class B(2003-4) Notes are Outstanding, there shall at all times be an agent appointed to calculate
LIBOR for each Interest Period (the “Calculation Agent”). The Issuer hereby initially appoints the Indenture Trustee as the Calculation Agent for purposes of determining LIBOR for each Interest Period. The Calculation Agent may be
removed by the Issuer at any time. If the Calculation Agent is unable or unwilling to act as such or is removed by the Issuer, or if the Calculation Agent fails to determine LIBOR for an Interest Period, the Issuer shall promptly appoint a
replacement Calculation Agent that does not control or is not controlled by or under common control with the Issuer or its Affiliates. The Calculation Agent may not resign its duties, and the Issuer may not remove the Calculation Agent, without a
successor having been duly appointed. 
  

 8 

 (b) On each LIBOR Determination Date, the Calculation Agent shall determine LIBOR on the basis of the
rate for deposits in United States dollars for a one-month period which appears on Telerate Page 3750 as of 11:00 a.m., London time, on such date. If such rate does not appear on Telerate Page 3750, the rate for that LIBOR Determination Date shall
be determined on the basis of the rates at which deposits in United States dollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for a one-month period. The
Calculation Agent shall request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, the rate for that LIBOR Determination Date shall be the arithmetic mean of
the quotations. If fewer than two quotations are provided as requested, the rate for that LIBOR Determination Date will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the Beneficiary, at approximately 11:00
a.m., New York City time, on that day for loans in United States dollars to leading European banks for a one-month period. 
  
 (c) The Note Interest Rate applicable to the then current and the immediately preceding Interest Periods may be obtained by telephoning the Indenture
Trustee at its corporate trust office at (212) 815-3247 or such other telephone number as shall be designated by the Indenture Trustee for such purpose by prior written notice by the Indenture Trustee to each Noteholder from time to time.

shall send to the Indenture Trustee, the Issuer and the Beneficiary, by facsimile transmission, notification of LIBOR for the following Interest Period. 
  
 Section 2.05. Payments of Interest and Principal. 
  
 (a) Any installment of interest or principal, if any, payable on any Class B(2003-4) Note which is punctually paid or duly provided for by the Issuer and
the Indenture Trustee on the applicable Interest Payment Date or Principal Payment Date shall be paid by the Paying Agent to the Person in whose name such Class B(2003-4) Note (or one or more Predecessor Notes) is registered on the Record Date, by
wire transfer of immediately available funds to such Person’s account as has been designated by written instructions received by the Paying Agent from such Person not later than the close of business on the third Business Day preceding the date
of payment or, if no such account has been so designated, by check mailed first-class, postage prepaid to such Person’s address as it appears on the Note Register on such Record Date, except that with respect to Notes registered on the Record
Date in the name of the nominee of Cede & Co., payment shall be made by wire transfer in immediately available funds to the account designated by such nominee. 
  
 (b) The right of the Class B(2003-4) Noteholders to receive payments from the Issuer will terminate on the first Business
Day following the Class B(2003-4) Termination Date.

2.06. Form of Delivery of Class B(2003-4) Notes; Depository; Denominations.

Documents to which it is a party has been or will be duly executed by the

are accurate in all material respects and do not contain any untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements made therein, in light of the circumstances under which they were
made, not misleading.

          (k) Manner of Offering. Assuming the Purchaser's representations and
warranties contained in Section 3.2 are true and correct, based on legal
opinions received from Jehu Hand, (a) the Securities are being offered and sold
to the Purchaser without registration under the Securities Act in a private
placement that is exempt from registration pursuant to Rule 504 of Regulation D
of the Securities Act and without registration under the Colorado Securities Act
of the Colorado Revised Statues (the "Colorado Act") in reliance upon the
exemption provided by Section 11-51-308 of the Colorado Act and regulation
51-3.13B promulgated

                                       11

thereunder; and (b) accordingly, the Securities are being issued without
restriction and may be freely traded pursuant to Rule 504 of Regulation D of the
Securities Act.

          (l) Non-Registered Offering. Neither the Company nor any Person acting
on its behalf has taken or will take any action (including, without limitation,
any offering of any securities of the Company under circumstances which would

the Securities to the registration requirements of Section 5 of the Securities
Act.

          (m) Not a Reporting Company; Eligibility to use Exemption under
504(b). As of the date hereof, the Company is not subject to the reporting
requirements of Section 13 or Section 15(d) of the Exchange Act. The Company has

the legal opinions from Jehu Hand, the Company is eligible to issue securities

the Securities Act. The Company is a development stage company that has a
specific business plan that is other than to engage in a merger or acquisition
with an unidentified company or companies.

contemplated in this Agreement and the Merger Agreement, there are no material

or warranty with respect to itself or the transactions contemplated hereby other
than those specifically set forth in Section 3.1 hereof.

represents and warrants to the Company all of which shall survive the
Post-Closing until the earlier of two years from the date hereof and the date
the Debentures have been converted or redeemed:

          (a) Organization; Authority. The Purchaser is a limited liability
company, duly organized, validly existing and in good standing under the laws of
Colorado with the requisite power and authority to enter into and to consummate
the transactions contemplated hereby and by the other Transaction Documents and
otherwise to carry out its obligations hereunder and thereunder. The acquisition
of the Debentures to be purchased by the Purchaser hereunder has been duly
authorized by all necessary action on the part of the Purchaser. This Agreement
has been duly executed and delivered by the Purchaser and constitutes the valid
and legally binding obligation of the Purchaser, enforceable against it in

applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to, or affecting generally the enforcement of, creditors rights and
remedies or by other general principles of equity.

          (b) Investment Intent. The Purchaser is acquiring the Debentures to be
purchased by it hereunder, and will acquire the Underlying Shares relating to
such Debentures, for its own account for investment purposes only and not with a
view to or for distributing or

                                       12

<PAGE>

reselling such Debentures or Underlying Shares or any part thereof or interest
therein, without prejudice, however, to such Purchaser's right, subject to the
provisions of this Agreement, at all times to sell or otherwise dispose of all
or any part of such Debentures or Underlying Shares in compliance with
applicable federal and state securities laws.

          (c) Purchaser Status. At the time the Purchaser was offered the
Debentures to be acquired by it hereunder, it was, at the date hereof it is and
at the Post-Closing it will be an "accredited investor" as defined in Rule
501(a) under the Securities Act. Purchaser is a resident in the State of
Colorado and no other jurisdiction.

          (d) Experience of Purchaser. The Purchaser, either alone or together
with its representatives, has such knowledge, sophistication and experience in
business and financial matters so as to be capable of evaluating the merits and
risks of an investment in the Securities to be acquired by it hereunder, and has
so evaluated the merits and risks of such investment.

          (e) Ability of Purchaser to Bear Risk of Investment. The Purchaser is
able to bear the economic risk of an investment in the Securities to be acquired
by it hereunder and, at the present time, is able to afford a complete loss of
such investment.

          (f) Prohibited Transactions. The securities to be acquired by the
Purchaser hereunder are not being acquired, directly or indirectly, with the
assets of any "employee benefit plan," within the meaning of Section 3(3) of the
Employment Retirement Income Security Act of 1974, as amended.

          (g) Access to Information. The Purchaser acknowledges receipt of the
Disclosure Documents and further acknowledges that it has been afforded (i) the
opportunity to ask such questions as it has deemed necessary of, and to receive
answers from, representatives of the Company concerning the terms and conditions
of the Securities and the merits and risks of investing in the Securities; (ii)
access to information about the Company and the Company's financial condition,
results of operations, business, properties, management and prospects sufficient
to enable it to evaluate its investment in the Securities; and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an
informed investment decision with respect to the investment and to verify the
accuracy and completeness of the information contained in the Disclosure
Documents.

          (h) Reliance. The Purchaser understands and acknowledges that (i) the
Debentures being offered and sold to it hereunder are being offered and sold
without registration under the Securities Act in a private placement that is
exempt from the registration provisions of the Securities Act under Rule 504 of
Regulation D under the Securities Act and (ii) the availability of such
exemption depends in part on, and that the Company will rely upon the accuracy
and truthfulness of, the foregoing representations and such Purchaser hereby
consents to such reliance.

     The Company acknowledges and agrees that the Purchaser makes no
representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in this Section 3.2.

     4.1 Manner of Offering. The Securities are being issued pursuant to Rule
504 (b) of Regulation D of the Securities Act. Based on the legal opinions from
Jehu Hand, the Securities will be exempt from restrictions on transfer, and will
carry no restrictive legend with respect to the exemption from registration
under the Securities Act. The Company will use its commercially reasonable best
efforts to insure that it takes no actions that would jeopardize the
availability of the exemption from registration under Rule 504(b) for the
Securities and, if for any reason such exemption becomes unavailable due to the
Company's action or failure to act, the Company shall cause the Securities to be
registered under the Securities Act as required by Section 4.29.

Securities, and unless and until the Securities are assumed by ISV or the

promptly furnish to the Purchaser financial information similar to that required
to be reported in annual and quarterly reports comparable to those required by
Section 13(a) or 15(d) of the Exchange Act (the "Non-Public Filings").

     4.3 Notice of Certain Events. The Company shall, on a continuing basis, as
long as the Purchaser owns any of the Securities, (i) advise the Purchaser
promptly after obtaining knowledge of, and, if requested by the Purchaser,
confirm such advice in writing, of (A) the issuance by any state securities
commission of any stop order suspending the qualification or exemption from
qualification of the Securities, for offering or sale in any jurisdiction, or
the initiation of any proceeding for such purpose by any state securities
commission or other regulatory authority, or (B) any event that makes any
statement of a material fact made by the Company in Section 3.1 or in the
Disclosure Documents untrue or that requires the making of any additions to or
changes in Section 3.1 or in the Disclosure Documents in order to make the
statements therein, in each case at the time such Disclosure Documents were
delivered to the Purchaser and in the light of the circumstances under which
they were made, not misleading, (ii) use its commercially reasonable best
efforts to prevent the issuance of any stop order or order suspending the
qualification or exemption from qualification of the Securities under any state
securities or Blue Sky laws, and (iii) if at any time any state securities
commission or other regulatory authority shall issue an order suspending the
qualification or exemption from qualification of the Securities under any such
laws, use its commercially reasonable best efforts to obtain the withdrawal or
lifting of such order at the earliest possible time.

     4.4 Copies and Use of Disclosure Documents and Non-Public Filings. The
Company (or, following the Post-Closing, ISV) shall furnish the Purchaser,
without charge, as many copies of the Disclosure Documents and the Non-Public

reasonably request. The Company consents to the use of the Disclosure Documents
and the Non-Public Filings and any amendments and supplements to any of them by
the Purchaser in connection with resales of the Securities.

                                       14

<PAGE>

     4.5 Modification to Disclosure Documents. If any event shall occur as a
result of which, in the reasonable judgment of the Company or the Purchaser, it
becomes necessary or advisable to amend or supplement any of the Disclosure
Documents or the Non-Public Filings in order to make the statements therein, at
the time such Disclosure Documents or the Non-Public Filings were delivered to
the Purchaser and in the light of the circumstances under which they were made,
not misleading, or if it becomes necessary to amend or supplement any of the
Disclosure Documents or the Non-Public Filings to comply with applicable law,
the Company shall as soon as practicable prepare an appropriate amendment or
supplement to each such document in form and substance reasonably satisfactory
to both the Purchaser and Company so that (i) as so amended or supplemented,
each such document will not include an untrue statement of material fact or omit
to state a material fact necessary in order to make the statements therein, in
the light of the circumstances existing at the time it is delivered to the
Purchaser, not misleading and (ii) the Disclosure Documents and the Non-Public
Filings will comply with applicable law in all material respects.

     4.6 Blue Sky Laws. The Company shall cooperate with the Purchaser in
connection with the exemption from registration of the Securities under the
securities or Blue Sky laws of such jurisdictions as the Purchaser may request;
provided, however, that the Company shall be not required in connection
therewith to (a) qualify as a foreign corporation where they are not now so

and pay all necessary state filing or notice fees to enable the Company to sell
the Securities to the Purchaser.

reasonable best efforts to ensure that no Affiliate shall sell, offer for sale
or solicit offers to buy or otherwise negotiate in respect of any security (as

offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities to the Purchaser.

     4.8 Furnishing of Rule 144(c) Materials. The Company shall, for so long as
any of the Securities remain outstanding and during any period in which the
Company is not subject to Section 13 or 15(d) of the Exchange Act, make
available to any registered holder of the Securities ("Holder" or "Holders") in
connection with any sale thereof and any prospective purchaser of such
Securities from such Person, such information in accordance with Rule 144(c)(2)
promulgated under the Securities Act as is required to sell the Securities under
Rule 144 promulgated under the Securities Act.

     4.9 Solicitation Materials. The Company shall not (i) distribute any
offering materials in connection with the offering and sale of the Debentures or
the Underlying Shares other than the Disclosure Documents and any amendments and
supplements thereto prepared in compliance herewith or (ii) solicit any offer to
buy or sell the Debentures or the Underlying Shares by means of any form of
general solicitation or advertising.

the full conversion of the Debentures.

          (b) After the Post-Closing Date, if not otherwise publicly available,

shall (a) use its commercially reasonable best efforts to maintain the listing
of its Common Stock on the AMEX, OTCBB or such other exchange on which the
Common Stock is then listed until expiration of each of the periods during which
the Debentures may be converted and (b) shall provide to the Purchaser evidence
of such listing. After the Post-Closing Date, the references in this Section
4.12 to Company and Common Stock shall be deemed references to ISV and the

simultaneously with the execution and delivery of this Agreement, the escrow
agreement attached hereto and made part hereof as Exhibit F (the "Escrow
Agreement"), and to issue into escrow (A) the certificates to be held by the
Escrow Agent, registered in the name of the Purchaser and without any
restrictive legend of any kind, pursuant to the terms of such escrow and (B) the

Share Limit") and to Section 4.14(e), the Company agrees that, at any time the
conversion price of the Debentures is such that the number of Escrow Shares for
the Debentures is less than 200% of the number of shares of Common Stock that
would be needed to satisfy full conversion of all of such Debentures then
outstanding, given the then current conversion price (the "Full Conversion
Shares"), upon five (5) Business Days written notice of such circumstance to the
Company by the Purchaser and/or the Escrow Agent, the Company shall issue
additional share certificates in

Conversion Shares.

     (c) The Purchaser shall not be entitled to convert the First Debenture A,
First Debenture B and the Second Debenture into a number of shares of Common
Stock exceeding the Maximum Share Limit.

     (d) Subject to Section 4.14(e), if the Per Share Market Value of the Common
Stock is such that the aggregate number of shares of Common Stock issued and
then issuable upon conversion of the Debentures would exceed 5,000,000 shares
(as adjusted for stock splits, reverse stock splits, and the like), then the
Company may, at its option, (a) increase the Maximum Share Limit to comply with
Section 4.14(b) or (b) redeem the unconverted amount of the Debentures in whole
or in part at one hundred forty percent (140%) of the unconverted amount of the
Debentures being redeemed plus accrued interest thereon.

     (e) After the Post-Closing Date, if ISV is required or elects pursuant to
this Section 4.14 to issue and deliver additional shares of common stock of ISV
(the "Additional Shares") to the Escrow Agent and such issuance would trigger
the shareholder approval requirements set forth in Section 712 of the AMEX
Company Guide, as then in effect or any equivalent rule or regulation of AMEX,
or would require an increase in the number of shares of common stock of ISV
authorized to be issued under the ISV Certificate of Incorporation, or, in the
event ISV is not at such time listed on AMEX, any equivalent rule or regulation
of any stock market, exchange or OTCBB on which the common stock of ISV is then
listed (collectively, "Shareholder Approval Rules"), then prior to issuing and
delivering such Additional Shares to the Escrow Agent and in accordance with any
applicable Shareholder Approval Rules (i) ISV shall immediately prepare and file
a proxy statement soliciting its stockholders' vote on a proposal to issue three
times the number of Additional Shares sufficient to cover 200% of the Full
Conversion Shares (the "Proposal") (provided that in no event shall ISV ever be
required to issue Escrow Shares exceeding 200% of the number of shares of its
common stock that will at such time be needed to satisfy full conversion of all
such Debentures then outstanding, given the then current conversion price) and
thereafter, as soon as allowed under the Exchange Act, the charter documents of
ISV and any other applicable law, rule or regulation, hold a special stockholder
meeting to vote upon the Proposal; (ii) ISV shall not be required to hold more
than one stockholder meeting to obtain such approval and shall not be required
to hire more than one proxy solicitor in connection with such special
stockholder meeting; and (iii) notwithstanding any other provision of this
Agreement or the Debentures, ISV shall not be required to issue and deliver the
Additional Shares to the Escrow Agent unless such issuance and delivery complies
with all applicable Shareholder Approval Rules, and the Escrow Agent can possess
the Additional Shares without violating any applicable Shareholder Approval
Rules.

     4.15 Attorney-in-Fact. To effectuate the terms and provisions of this
Agreement, the Escrow Agreement and the Note, the Company hereby agrees to give
a power of attorney as is evidenced by Exhibit G annexed hereto. Other than acts
of willful misconduct or gross negligence, all acts done under such power of
attorney are hereby ratified and approved and neither the Attorney-in-Fact nor
any designee or agent thereof shall be liable for any acts of

                                       17

<PAGE>

commission or omission, for any error of judgment or for any mistake of fact or
law, as long as the Attorney-in-Fact is operating within the scope of the power
of attorney and this Agreement and its exhibits. The power of attorney, being
coupled with an interest, shall be irrevocable while any of the Debentures
remain unconverted or any portion of this Agreement or the Escrow Agreement
remains unsatisfied. In addition, the Company shall give the Attorney-in-Fact
resolutions executed by the Board of Directors of the Company which authorize
transfers of the Debentures, future issuances of the Underlying Shares for the
Debentures, and which resolutions state that they are irrevocable while any of
the Debentures remain unconverted, or any portion of this Agreement or the
Escrow Agreement remains unsatisfied.

     4.16 Indemnification.

          (a) Indemnification

               (i) The Company shall, notwithstanding termination of this
     Agreement, indemnify and hold harmless the Purchaser and its officers,
     directors, agents, employees and affiliates, each Person who controls the
     Purchaser (within the meaning of Section 15 of the Securities Act or
     Section 20 of the Exchange Act) (each such Person, a "Control Person") and
     the officers, directors, agents, employees and affiliates of each such
     Control Person, to the fullest extent permitted by applicable law, from and
     against any and all losses, claims, damages, liabilities, costs (including,
     without limitation, costs of preparation and reasonable attorneys' fees)
     and expenses (collectively, "Losses"), as incurred, arising out of, or
     relating to, a breach or breaches of any representation, warranty, covenant
     or agreement by the Company under this Agreement or any other Transaction
     Document.

               (ii) The Purchaser shall, notwithstanding termination of this
     Agreement, indemnify and hold harmless the Company, its officers,
     directors, agents and employees, each Control Person of the Company and the
     officers, directors, agents and employees of each Control Person, to the
     fullest extent permitted by applicable law, from and against any and all
     Losses, as incurred, arising out of, or relating to, a breach or breaches
     of any representation, warranty, covenant or agreement by the Purchaser
     under this Agreement or any other Transaction Documents.

          (b) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

                                       18

<PAGE>

          An Indemnified Party shall have the right to employ separate counsel
in any such] Proceeding and to participate in, but not control, the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed
to pay such fees and expenses; or (2) the Indemnifying Party shall have failed
promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impeded parties) include
both such Indemnified Party and the Indemnifying Party, and such Indemnified
Party shall have been advised by counsel that a conflict of interest is likely
to exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of the claim against the Indemnified Party but will
retain the right to control the overall Proceedings out of which the claim arose
and such counsel employed by the Indemnified Party shall be reasonably
acceptable to the Indemnifying Party and shall be at the expense of the
Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending Proceeding in respect of which any
Indemnified Party is a party, unless such settlement includes an unconditional
release of such Indemnified Party from all liability on claims that are the
subject matter of such Proceeding, provided, however, the Indemnifying Party may
settle or compromise any asserted liability without the consent of the
Indemnitee so long as such settlement or compromise releases the Indemnitee and
does not include any admission or statement of fault against the Indemnitee.

          All fees and expenses of the Indemnified Party to which the
Indemnified Party is entitled hereunder (including reasonable fees and expenses
to the extent incurred in connection with investigating or preparing to defend
such Proceeding in a manner not inconsistent with this Section) shall be paid to
the Indemnified Party, as incurred, within twenty (20) Business Days of written
notice thereof to the Indemnifying Party.

          No right of indemnification under this Section 4.16 shall be available
as to a particular Indemnified Party if there is a non-appealable final judicial
determination that such Losses arise solely or substantially out of the
negligence or bad faith of such Indemnified Party in performing the obligations
of such Indemnified Party under this Agreement or a breach by such Indemnified
Party of its obligations under this Agreement.

          (c) Contribution. If a claim for indemnification under Section 4.16(a)
is unavailable to an Indemnified Party or is insufficient to hold such
Indemnified Party harmless for any Losses in respect of which this Section 4.16
would apply by its terms (other than by reason of exceptions provided in this
Section 4.16), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses in such proportion as is
appropriate to reflect the relative benefits received by the Indemnifying Party
on the one hand and the Indemnified Party on the other and the relative fault of
the Indemnifying Party and Indemnified Party in connection with the actions or
omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified
Party shall be determined by reference to, among other things, whether there was
a judicial determination that

                                       19

<PAGE>

such Losses arise in part out of the negligence or bad faith of the Indemnified
Party in performing the obligations of such Indemnified Party under this
Agreement or the Indemnified Party's breach of its obligations under this
Agreement. The amount paid or payable by a party as a result of any Losses shall
be deemed to include any attorneys' or other fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in
this Section was available to such party.

          (d) Non-Exclusivity. The indemnity and contribution agreements
contained in this Section are in addition to any obligation or liability that
the Indemnifying Parties may have to the Indemnified Parties.

     4.17 Exclusivity. (a) During the four month period commencing on the
Post-Closing Date (the "Restriction Period"), (A) except for the First Debenture
B, the Company and its Affiliates shall not issue or offer (i) any floorless
convertible security and (ii) any security issued pursuant to Rule 504 of
Regulation D promulgated under the Securities Act and (B) the Company and its
Affiliates shall not offer any equity lines of credit. The Company may request
that the restrictions in this Section 4.17(a) be waived. Except as specifically
set forth above, the Company may engage in any other debt or equity financing
during the Restriction Period.

          (b) Subject to Section 4.17(a), during the thirty (30) days
immediately following the Restriction Period (the "Rights Period") the Company
and its Affiliates hereby grant to the Purchaser, or its successors or assigns,
a right of first refusal to participate in any and all additional equity or debt
financings (the "New Financing") of the Company or its Affiliates ("Right of
First Refusal"). For the purposes of this Section 4.17(b), "New Financing" shall
not include (i) up to two (2) million shares of Common Stock, options to
purchase up to two (2) million shares of Common Stock or some combination of
Common Stock and options to purchase Common Stock that would together total,
when the options were exercised, two (2) million shares of Common Stock, issued
to employees or directors of the Company pursuant to any stock option plan or
stock purchase plan of the Company or (ii) Common Stock issued upon the exercise
of convertible securities of the Company outstanding on the date hereof or
issued in connection with this Agreement. The Company or its Affiliates shall
notify the Purchaser in writing immediately upon its intent to issue the New
Financing (the "Company Notice") and the Purchaser shall be entitled to exercise
the Right of First Refusal by notifying the Company or its Affiliates in writing
of such election within five (5) Business Days of its receipt of the Company
Notice. The Company Notice shall include all of the terms and conditions of the
proposed New Financing. If the Purchaser does not respond within five (5)
Business Days of its receipt of the Company Notice, the Company or its
Affiliates have the right to offer the New Financing to third parties on the
same terms offered to the Purchaser for five (5) Business Days with a definitive
purchase agreement, related to the New Financing, to be executed no later than
forty-five (45) Business Days after the date of the Company Notice to Purchaser.
The Right of First Refusal shall be exercisable following the Rights Period if
the Company Notice is delivered within the Rights Period.

     4.18 Purchaser's Ownership of Common Stock. In addition to and not in lieu
of the limitations on conversion set forth in the Debentures, the conversion
rights of the Purchaser set forth in the Debentures shall be limited, solely to
the extent required, from time to time, such

                                       20

<PAGE>

that, unless the Purchaser gives written notice 75 days in advance to the
Company of the Purchaser's intention to exceed the Limitation on Conversion as
defined herein, with respect to all or a specified amount of the Debentures and
the corresponding number of the Underlying Shares in no instance shall the
Purchaser (singularly, together with any Persons who in the determination of the
Purchaser, together with the Purchaser, constitute a group as defined in Rule
13d-5 of the Exchange Act) be entitled to convert the Debentures to the extent
such conversion would result in the Purchaser beneficially owning more than five
percent (5%) of the outstanding shares of Common Stock of the Company. For these
purposes, beneficial ownership shall be defined and calculated in accordance
with Rule 13d-3, promulgated under the Exchange Act (the foregoing being herein
referred to as the "Limitation on Conversion"); provided, however, that the
Limitation on Conversion shall not apply to any forced or automatic conversion
pursuant to this Agreement or the Debentures; and provided, further that if the
Purchaser shall have declared an Event of Default and, if a cure period is
provided, the Company shall not have properly and fully cured such Event of
Default within any such cure period, the provisions of this Section 4.18 shall
be null and void from and after such date. The Company shall, promptly upon its
receipt of a Notice of Conversion tendered by the Purchaser (or its sole
designee) for the Debentures, as applicable, notify the Purchaser by telephone
and by facsimile (the "Debenture Notice") of the number of shares of Common
Stock outstanding on such date and the number of Underlying Shares, which would
be issuable to the Purchaser (or its sole designee, as the case may be) if the
conversion requested in such Notice of Conversion were effected in full and the
number of shares of Common Stock outstanding giving full effect to such
conversion whereupon, in accordance with the Debentures, notwithstanding
anything to the contrary set forth in the Debentures, the Purchaser may, by
written notice to the Company within one (1) Business Day of its receipt of the
Debenture Notice by facsimile, revoke such conversion to the extent (in whole or
in part) that such Purchaser determines that such conversion would result in the
ownership by such Purchaser of shares of Common Stock in excess of the
Limitation on Conversion. The Debenture Notice shall begin the 75 day advance
notice required in this Section 4.18.

     4.19 Purchaser's Rights if Trading in Common Stock is Suspended. If the
Common Stock is listed on any exchange, then at any time after the Post-Closing
if trading in the shares of the Common Stock is suspended (and not reinstated
within ten (10) Trading Days) on such stock exchange or market upon which the
Common Stock is then listed for trading (other than as a result of the
suspension of trading in securities on such market generally or temporary
suspensions pending the release of material information), or the Common Stock is
delisted from the OTCBB (and not reinstated within ten (10) Trading Days), and,
in either case, if not so reinstated, is not listed on another exchange, market
or the OTCBB, within such ten (10) Trading Day period, then, at the option of
the Purchaser exercisable by giving written notice to the Company (the
"Redemption Notice"), the Company shall redeem, as applicable, all of the
Debentures and Underlying Shares owned by such Purchaser within seven (7)
Business Days at an aggregate purchase price equal to the sum of:

          (i) the product of (1) the average Per Share Market Value for the five
(5) Trading Days immediately preceding (a) the date of the Redemption Notice,
(b) the date of payment in full of the repurchase price under this Section 4.19
recalculated as of such payment date, or (c) the day when the Common Stock was
suspended, delisted or deleted from trading,

                                       21

<PAGE>

whichever is greater, multiplied by (2) the aggregate number of Underlying
Shares then held and owned by such Purchaser;

          (ii) the greater of (A) the outstanding principal amount and accrued
and unpaid interest on the Debentures owned by such Purchaser and (B) the
product of (1) the average Per Share Market Value for the five (5) Trading Days
immediately preceding (a) the date of the Redemption Notice, (b) the date of
payment in full of the repurchase price under this Section 4.19 recalculated as
of such payment date, or (c) the day when the Common Stock was suspended,
delisted or deleted from trading, whichever is greater, and (2) the aggregate
number of Underlying Shares issuable upon the conversion of the outstanding
Debentures then held and owned by the Purchaser utilizing the conversion
procedures contained in the Debentures (without taking into account the
Limitation on Conversion described in Section 4.18 hereof); and

          (iii) interest on such amounts set forth in (i) and (ii) above
accruing from the seventh (7th) Business Day after the date of the Redemption
Notice until the repurchase price under this Section 4.19 is paid in full, at
the rate of eight percent (8%) per annum;

provided, however, if the Note has not been paid in full by the Purchaser to the
Company (whether or not it is otherwise then due or payable by its terms), (i)
any payments from the Company to the Purchaser pursuant to this Section 4.19
will be offset by the principal amount of the Note and (ii) "Debentures" shall
specifically refer to First Debenture A, First Debenture B and the Second
Debenture.

     4.20 No Violation of Applicable Law. Notwithstanding any provision of this
Agreement to the contrary, if the redemption of the Debentures or the Underlying
Shares otherwise required under this Agreement or the Debentures would be
prohibited by the relevant provisions of Delaware law, such redemption shall be
effected as soon as it is permitted under such law; provided, however, that
interest payable by the Company with respect to any such redemption shall accrue
in accordance with Section 4.19.

     4.21 Redemption Restrictions. Notwithstanding any provision of this
Agreement to the contrary, if any redemption of the Debentures or the Underlying
Shares otherwise required under this Agreement or the Debentures would be
prohibited in the absence of consent from any lender to the Company, or by the
holders of any class of securities of the Company, the Company shall use its
commercially reasonable best efforts to obtain such consent as promptly as
practicable after any such redemption is required. Interest payable by the
Company with respect to any such redemption shall accrue in accordance with
Section 4.19 until such consent is obtained. Nothing contained in this Section
4.21 shall be construed as a waiver by the Purchaser of any rights it may have
by virtue of any breach of any representation or warranty of the Company herein
as to the absence of any requirement to obtain any such consent.

     4.22 No Other Registration Rights. During the period commencing on the date
hereof and ending on the Post-Closing Date, the Company shall not file any
registration statement that provides for the registration of shares of Common
Stock to be sold by security holders of the Company, other than the Purchaser
and/or its respective Affiliates or assigns, without the prior written consent
of the Purchaser or its assigns, provided, however, that the limitation on the
right to file registration statements contained in this Section 4.22 shall not
apply to registration

                                       22

<PAGE>

statements relating solely to (i) employee benefit plans, notwithstanding the
inclusion of a resale prospectus for securities received under any such employee
benefit plan, or (ii) business combinations not otherwise prohibited by the
terms of this Agreement or the other Transaction Documents. This registration
restriction is in addition to the Company's registration restrictions set forth
in Section 4.24.

     4.23 Merger or Consolidation. Until the earlier of (a) the full conversion
of the Debentures and (b) the Maturity Date of the Debentures (as that term is
defined in the Debentures), the Company will not, in a single transaction or a
series of related transactions (other than the Merger), (i) consolidate with or
merge with or into any other Person, or (ii) permit any other Person to
consolidate with or merge into it, unless (w) either (A) the Company shall be
the survivor of such merger or consolidation or (B) the surviving Person shall
expressly assume by supplemental agreement all of the obligations of the Company
under the Debentures, this Agreement and the other Transaction Documents; (x)
immediately before and immediately after giving effect to such transactions
(including any indebtedness incurred or anticipated to be incurred in connection
with the transactions), no Event of Default shall have occurred and be
continuing; (y) if the Company is not the surviving entity, such surviving
entity's common shares will be listed on either The New York Stock Exchange,
AMEX, Nasdaq National Market or Nasdaq SmallCap Market, or the OTCBB on or prior
to the closing of such transaction(s) and (z) the Company shall have delivered
to the Purchaser an officer's certificate and opinion of counsel, each stating
that such consolidation, merger (other than the Merger) or transfer complies
with this Agreement, that the agreements relating to such transaction(s) provide
that the surviving Person agrees to be bound by this Agreement and that all
conditions precedent in this Agreement relating to such transaction(s) have been
satisfied.

     4.24 Registration of Escrow Shares. (a) So long as the Purchaser and/or its
assigns owns any of the Securities and to the Company's knowledge, the
Underlying Shares would not be freely transferable without registration, the
Company agrees not to file a registration statement with the SEC without
Purchaser's express written consent, other than on Form 10, Form S-4 (except for
a public reoffering or resale) or Form S-8 without first having registered (or
simultaneous registering) the Registrable Securities for resale under the
Securities Act and in such states of the United States as the holders thereof
shall reasonably request.

     (b) If the Company shall propose to file with the SEC any registration
statement other than a Form 10, Form S-4 (except for a public reoffering or
resale) or Form S-8 which would cause, or have the effect of causing, the
Company to become a Reporting Issuer or to take any other action, other than the
sale of the Debentures to the Purchaser hereunder, the effect of which would be
to cause the Underlying Shares to be restricted securities (as such term is
defined in Rule 144 promulgated under the Securities Act), the Company agrees to
give written notification of such to the holders of the Securities at least two
weeks prior to such filing or taking of the proposed action. If any of the
Securities are then outstanding, the Company agrees to include in such
registration statement the Registrable Securities unless the Underlying Shares
would be freely transferable upon conversion of the Debentures without such
registration, so as to permit the public resale thereof.

     If the registration of which the Company gives notice is for a registered
public offering involving an underwriting, the Company will so advise the
holders of the Securities. In such

                                       23

<PAGE>

event, these registration rights shall be conditioned upon such holder's
participation in such underwriting and the inclusion of such holder's
Registrable Securities in the underwriting to the extent provided herein. All
holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriter selected by the Company. In the event that the lead or managing
underwriter in its good faith judgment determines that material adverse market
factors require a limitation on the number of shares to be underwritten, the
underwriter may limit the number of Registrable Securities. In such event, the
Company shall so advise all holders of securities requesting registration, and
the number of shares of the Registrable Securities that are entitled to be
included in the registration and underwriting shall be allocated pro rata among
all holders and other participants, including the Company, in proportion, as
nearly as practicable, to the respective amounts of Registrable Securities and
other securities which they had requested to be included in such registration
statement at the time of filing the registration statement. If any holder
disapproves of the terms of any such underwriting, he may elect to withdraw
therefrom by written notice to the Company and the underwriter, provided such
notice is delivered within sixty (60) days of full disclosure of such terms to
such holder, without thereby affecting the right of such holder to participate
in subsequent offerings hereunder.

     (c) Notwithstanding the foregoing, if the Company for any reason shall have
taken any action, other than the sale of the Debentures to the Purchaser
hereunder, the effect of which would be to cause the Registrable Securities to
be restricted securities (as such term is defined in Rule 144 promulgated under
the Securities Act), the Company agrees to use its commercially reasonable best
efforts to file a registration statement with the SEC and use its commercially
reasonable best efforts to have such registration statement declared effective
by the SEC which would permit the public resale of the Registrable Securities
under the Securities Act and in such states of the United States as the holders
thereof shall reasonably request.

     (d) The Company agrees to use its commercially reasonable best efforts keep
any registration required pursuant to this Section 4.24 continuously effective
under the Securities Act and with such states of the United States as the
holders of the Registrable Securities shall reasonably request until the earlier
of (i) the date on which all of the Registrable Securities covered by any such
registration have been sold, (ii) two (2) years from the effective date of any
such registration, or (iii) the date on which all of the Registrable Securities
may be sold without restriction pursuant to Rule 144 of the Securities Act. All
costs and expenses of any such registration and related Blue Sky filings and
maintaining continuous effectiveness of such registration and filings shall be
borne by the Company, other than underwriters and brokers, fees and commissions.

     (e) The Escrow Shares shall be registered by the Company under the
Securities Act if required by Section 4.29 and subject to the conditions stated
therein.

     (f) Each holder of Registrable Securities agrees to cooperate and assist
the Company in preparing and filing any registration statement required to be
filed pursuant to this Agreement, including, without limitation, providing the
Company with such information about the holder and answering such questions as
deemed reasonably necessary by the Company in order to complete such
registration statement. Until such time as the Company is no longer required to
keep the registration statement effective, each holder of Registrable Securities
agrees to immediately

                                       24

<PAGE>

notify the Company of any change to the information provided to the Company in
connection with the preparation or maintenance of the registration statement,
and each such holder agrees to certify to the accuracy and completeness of all
information provided by it to the Company or its representatives in connection
with such registration statement.

     4.25 Liquidated Damages. The Company understands and agrees that a breach
by the Company of Section 4.1, Section 4.24, Section 4.29, Section 4.30 or an
Event of Default as contained in this Agreement and/or any other Transaction
Document will result in substantial economic loss to the Purchaser, during the
period Purchaser owns the Securities which loss will be extremely difficult to
calculate with precision. Therefore, if, for any reason during the period
Purchaser owns the Securities, the Company breaches Sections 4.1, Section 4.24,
Section 4.29, Section 4.30 or fails to cure any Event of Default under Section
5.1 (a) (iii), (v), (vi) and (viii) within the time, if any, given to cure such
Event of Default, as compensation and liquidated damages for such breach or
default, and not as a penalty, the Company agrees to pay the Purchaser an amount
equal to the Purchase Price and the Purchaser, upon receipt of such payment,
shall return any unconverted Debentures to the Company. The Company shall, upon
demand, pay the Purchaser such liquidated damages by wire transfer of
immediately available funds to an account designated by the Purchaser. Nothing
herein shall limit the right of the Purchaser to pursue actual damages (less the
amount of any liquidated damages received pursuant to the foregoing) for the
Company's breach of Section 4.1, Section 4.24, Section 4.29, Section 4.30 or
failure to cure an Event of Default under Section 5.1 (a) (iii) (v) (vi) and
(viii), consistent with the terms of this Agreement.

     4.26 Short Sales. The Purchaser agrees neither it nor any of its Affiliates
will enter into any Short Sales (as hereinafter defined) until the earlier to
occur of the date that the Purchaser no longer owns the Debentures and the
Maturity Date. For purpose hereof, a "Short Sale" shall mean a sale of Common
Stock by the Purchaser or any of its Affiliates that is marked as a short sale
and that is made at a time when there is no equivalent offsetting long position
in the Common Stock by the Purchaser or such Affiliate. For the purposes of
determining whether there is an equivalent offsetting long position in the
Common Stock held by the Purchaser, shares of Common Stock issuable upon
conversion of the Debentures shall be deemed to be held long by the Purchaser
with respect to the Underlying Shares for which a Notice of Conversion is
delivered within two (2) Trading Days following the Trading Day that such Short
Sale is entered into. The Purchaser will comply with all rules and regulations
contained in the Securities Act and the Exchange Act.

     4.27 Fees. The Company will pay the following fees and expenses in
connection with the transactions contemplated hereby: (a) to G&P (i) legal fees
for document production in the amount of $20,000 and (ii) all reasonable
out-of-pocket expenses incurred in connection with such document production in
an amount not to exceed $5,000 and (b) to the Escrow Agent, $5,000 for the
escrow agent fee. ISV has already paid $20,000 to G&P. Unless paid prior, all
fees and expenses will be paid at Post-Closing and the Company and the Purchaser
hereby authorize and direct the Escrow Agent to deduct such fees and expenses
directly from escrow prior to distributing any funds to the Company. Except with
respect to the fees set forth in part (b) of this Section 4.27 and except as
otherwise set

                                       25

<PAGE>

forth in the Retainer Agreement, all fees and expenses shall be paid regardless
of whether the transactions contemplated hereby are closed or otherwise
completed. Except for the $20,000 already paid to G&P and except as otherwise
set forth in the Retainer Agreement, all fees to be paid hereunder shall have no
offsets, are non-refundable and non-cancelable.

     4.28 First Debenture B and Note. Notwithstanding anything contained herein,
in the Debentures, or in the Note to the contrary, the First Debenture B shall
not accrue interest, shall not be convertible, and shall not be subject to
repayment by the Company at its maturity, and the Note shall not be due and
payable and shall not be deemed part of the "Purchase Price" for purposes of
Section 4.25 hereof, unless and until:

          (i) the closing bid price per share of the common stock of ISV having
          been at or above the Fixed Conversion Price (as defined in the First
          Debenture A) (the "Initial Fixed Conversion Price") for thirty (30)
          consecutive Trading Days at any time from the date hereof until the
          Maturity Date (as defined in the First Debenture B); and

          (ii) the number of Escrow Shares for the aggregate principal amount of
          the First Debenture A and the Second Debenture then outstanding and
          First Debenture B is at least 200% of the number of shares of common
          stock of ISV that would be needed to satisfy full conversion of all
          such unconverted Debentures,

          provided, however, that if subparagraph (i) is satisfied and
          subparagraph (ii) is not, ISV shall increase in accordance with
          Section 4.14, the number of Escrow Shares to cover 200% of the number
          of shares of common stock of ISV that would be needed to satisfy full
          conversion of all of such Debenture pursuant to the procedures set
          forth in Section 4.14(e); provided, further, that, notwithstanding the
          foregoing, the First Debenture B shall not accrue interest, shall not
          be convertible, and shall not be subject to repayment by the Company
          at its maturity, and the Note shall not be deemed part of the
          "Purchase Price" for purposes of Section 4.25 hereof, unless and until
          the Note is paid in full by the Purchaser or its successors and
          assigns.

     4.29 Changes to Federal and State Securities Laws. If any of the Securities
require registration with or approval of any governmental authority under any
federal (including but not limited to the Securities Act or similar federal
statute then in force) or state law, or listing on any national securities
exchange, before they may be resold or transferred without any restrictions on
their resale or transfer for reasons including, but not limited to, a material
change in Rule 504 of Regulation D promulgated under the Securities Act or a
change to the exemption for sales made to Accredited Investors in the state in
which the Purchaser resides, the Company will, at its expense, (a) as
expeditiously as possible cause the Registrable Securities to be duly registered
or approved or listed on the relevant national securities exchange, as the case
may be, and (b) keep such registration, approval or listing, as the case may be,
continuously effective until the earlier of (i) the date on which all of the
Registrable Securities have been sold, (ii) two (2) years from the effective
date of any such registration, or (iii) the date on which all of the Securities
may be sold without restriction pursuant to Rule 144 of the Securities Act;
subject to the terms and limitations set forth in section 4.24. The Registrable
Securities shall be registered by the

                                       26

<PAGE>

Company under the Securities Act if required by Section 4.24 and subject to the
conditions stated therein.

     4.30 Merger Agreement. Immediately upon the Effective Date, all of the
transactions contemplated by the Merger Agreement annexed hereto as Exhibit C
shall be consummated in accordance with the terms thereof.

     4.31 Future Financing. If, at any time any of the Debentures are
outstanding, the Company, or its successors in interest due to mergers,
consolidations and/or acquisitions (the "Successors-in-Interest"), receives debt
or equity financing in an amount equal to or exceeding Five Million United
States dollars ($5,000,000) in a single transaction or series of related
transactions (excluding any portion of such financing consisting of forgiveness
of debt or other obligations and excluding the financing represented by this
Agreement and the Debentures), the Company or the Successors-in-Interest, as the
case may be, agrees to pay the Purchaser an amount equal to One Hundred Fifty
Percent (150%) of the then outstanding Debentures (the "Lump Sum Payment"). Upon
the Purchaser's receipt of the Lump Sum Payment, any and all remaining
obligations then outstanding between the Company or the Successors-in-Interest,
as the case may be, and Purchaser in connection with this Agreement and the
Debentures shall be deem satisfied, and the Agreement and the Debentures shall
be terminated. This provision shall survive both Closing and Post-Closing;
provided, however, if the Note has not been paid in full by the Purchaser to the
Company (whether or not it is otherwise then due or payable by its terms), (i)
any payments from the Company to the Purchaser pursuant to this Section 4.31
will be offset by the principal amount of the Note and (ii) "Debentures" shall
specifically refer to First Debenture A, First Debenture B and the Second
Debenture.

     4.32 Applicability of Agreements after Post-Closing. At the Effective Date
or upon the consummation of any other merger or other transaction pursuant to
which the Company's obligations under the Debentures are assumed by another
party (whether or not such assumption is joint and several), the Company shall
be released from, and have no further obligation pursuant to Sections 4.1
through 4.6, 4.8, 4.10, 4.12, 4.14, 4.16 through 4.27, 4.29 and 4.31 hereof, and
any reference to the Company in such sections shall instead be deemed to refer
solely to the party that assumes the debentures. Notwithstanding the foregoing
or anything else to the contrary contained in this Agreement, any references to
Disclosure Documents or representations, warranties and agreements or statements
of Company made in Section 3.1 or elsewhere contained in this Agreement
(including, without limitation, the above referenced sections) shall remain
references to the Company and not to ISV. ISV is not making or adopting any of
the Disclosure Documents or the representations, warranties and agreements made
in Section 3.1, all of which remain Disclosure Documents and representations,
warranties, and agreements of the Company.

     4.33 Second Debenture Restriction. The Purchaser shall not convert the
Second Debenture in a principal amount in excess of $3,625, unless and until the
First Debenture B becomes convertible by the Purchaser and subject to repayment
at its maturity by the Company and the Note is paid in full by the Purchaser.

                                       27

     4.34 Company's Right of Redemption. In addition to any right of the Company
to redeem any unconverted amount of the Debentures, in whole or in parts set
forth in this Agreement, the Company shall have any redemption right set forth
in the Debentures.

     injunction of any court of or governmental authority having competent
     jurisdiction;

               (ii) the Post-Closing shall not have occurred by the Post-Closing

     is reported under Item 2 that involves a change in the nature of ISV's
     business; Item 3; Item 4 (provided further, that as to Item 4, only if the

     dissemination of material information regarding ISV, and not reinstated or
     listed on another exchange, market or OTCBB within ten (10)

                                       28

Business Days following receipt by the Company of notice of such breach.

          (c) Prior to Post-Closing by the Company, by giving written notice of

the other Transaction Documents and such breach is not cured within five (5)

     5.2 Remedies. Notwithstanding anything else contained herein to the
contrary, if an Event of Default has occurred pursuant to Section 5.1, and only
with respect to Section 5.1(b) has not been cured within the cure period
provided for therein, the defaulting party shall be deemed in default hereof and
the non-defaulting party shall be entitled to pursue all available rights
without further notice. The defaulting party shall pay all attorney's fees and
costs incurred in enforcing this Agreement and the other Transaction Documents.
In addition, all unpaid amounts shall accrue interest at a rate of 8% per annum.

                                   ARTICLE VI

                      LEGAL FEES AND DEFAULT INTEREST RATE

under this Agreement or any other Transaction Document, the non-prevailing party
shall pay all reasonable costs and expenses (including but not limited to
reasonable attorney's fees, accountant's fees, appraiser's fees and
investigative fees) incurred in enforcing such rights. In the event of an
uncured Event of Default by any party hereunder, interest shall accrue on all

                                  MISCELLANEOUS

     7.1 Fees and Expenses. Except as set forth in this Agreement or in the

<PAGE>

fees of $5,000 to the Escrow Agent as set forth in Section 4.27 hereto and all
stamp and similar taxes and duties levied in connection with the issuance of the
Debentures (and, upon conversion, the Underlying Shares) pursuant hereto. The
Purchaser shall be responsible for any taxes (other than income taxes) payable
by the Purchaser that may arise as a result of the investment hereunder or the
transactions contemplated by this Agreement or any other Transaction Document.
Whether or not the transactions contemplated hereby and thereby are consummated
or this Agreement is terminated. The Company shall pay (i) all costs, expenses,
fees and all taxes incident to and in connection with: (A) the preparation,

Exhibits and Schedules annexed hereto, the Retainer Agreement and any other
Transaction Document contain the entire understanding of the parties with

amended except in a written instrument signed, in the case of an amendment, by
both the Company and the Purchaser, or, in the case of a waiver, by the party
against whom enforcement of any such waiver is sought. No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall
be deemed to be a continuing waiver in the future or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission of
either party to exercise any right hereunder in any manner impair the exercise
of any such right accruing to it thereafter.

     7.5 Headings. The headings herein are for convenience only, do not

any of the provisions hereof.

                                       31

<PAGE>

     7.6 Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties and their respective successors and permitted
assigns. This Agreement and any of the rights, interests or obligations
hereunder may be assigned by the Purchaser to an accredited investor without the
consent of the Company as long as such assignee agrees to be bound by this
Agreement. This Agreement and any of the rights, interests or obligations
hereunder may not be assigned by the Company without the prior written consent
of the Purchaser. It is agreed that the Company may assign all of the rights,
interests and obligations hereunder to ISV pursuant to the Merger Agreement.

     7.7 No Third Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other person, except in accordance with Section 4.16 and Section 7.14.

     7.8 Governing Law; Venue; Service of Process. The parties hereto
acknowledge that the transactions contemplated by this Agreement and the
exhibits hereto bear a reasonable relation to the State of New York. The parties
hereto agree that the internal laws of the State of New York shall govern this
Agreement and the exhibits hereto, including, but not limited to, all issues
related to usury. Any action to enforce the terms of this Agreement or any of
its exhibits shall be brought exclusively in the state and/or federal courts
situated in the County and State of New York. Service of process in any action
by the Purchaser to enforce the terms of this Agreement may be made by serving a

forth in this Agreement.

     7.9 Survival. The agreements and covenants of the parties contained in
Article IV and this Article VII shall survive the Post-Closing (or any earlier
termination of this Agreement) so long as any of the Securities are outstanding.

     7.10 Counterpart Signatures. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

     7.11 Publicity. The Company and the Purchaser shall consult with each other
in issuing any press releases or otherwise making public statements with respect
to the transactions contemplated hereby and neither party shall issue any such
press release or otherwise make any such public statement without the prior
written consent of the other, which consent shall not be unreasonably withheld
or delayed, unless counsel for the disclosing party deems such public statement
to be required by applicable federal and/or state securities laws. Except as
otherwise required by applicable law or regulation, the Company will not
disclose to any third party the names of the Purchaser.

<PAGE>

     7.12 Severability. In case any one or more of the provisions of this
Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affected or impaired thereby and the parties will attempt to agree
upon a valid and enforceable provision which shall be a reasonable substitute
therefore, and upon so agreeing, shall incorporate such substitute provision in
this Agreement.

     7.13 Limitation of Remedies. With respect to claims by the Company or the
Purchaser or any person acting by or through the Company or the Purchaser for
remedies at law or at equity relating to or arising out of a breach of this
Agreement, liability, if any, shall, in no event, include loss of profits or
incidental, indirect, exemplary, punitive, special or consequential damages of
any kind.

     7.14 Confidential Information. The Company and the Purchaser each
represents to ISV that, at all times, they have maintained in confidence all
non-public information regarding ISV (including the existence of the
transactions contemplated herein) received by them from ISV or its agents, and
covenants that it they will continue to maintain in confidence such information
until such information (a) becomes generally publicly available other than
through a violation of this provision by the Company and the Purchaser, or any
of their respective agents or (b) is required to be disclosed in legal
proceedings (such as by deposition, interrogatory, request for documents,
subpoena, civil investigation demand, filing with any governmental authority or
similar process), provided, however, that before making any use or disclosure in
reliance on this subparagraph (b) the Company and the Purchaser, as applicable,
shall give ISV at least fifteen (15) days prior written notice (or such shorter
period as required by law) specifying the circumstances giving rise thereto and
will furnish only that portion of the non-public information which is legally
required and will exercise its best efforts to obtain reliable assurance that
confidential treatment will be accorded any non-public information so furnished.

     7.15 Omnibus Provision. Anything contained herein or in the other
Transaction Documents notwithstanding, in the event that the Common Stock shall
become listed on the AMEX and subsequently ceases to be listed for trading on
the AMEX, then any reference thereto in this Agreement or the other Transaction
Documents shall be deemed to be a reference to (a) the principal national
securities exchange on which the Common Stock is then listed or admitted to
trading, or (b) if the Common Stock is not then listed or admitted to trading on
any national securities exchange, Nasdaq, or (c) if the Common Stock is not then
listed or admitted to trading on Nasdaq, OTCBB, or (d) if the Common Stock is
not then listed or admitted to trading on OTCBB, then the over-the-counter
market reported by the Pinksheets LLC (or similar organization or agency
succeeding to its functions of reporting prices).
