          2.5  Additional Shares.

               (a) After the Closing, subject to the specifications and
limitations in this Agreement, the Purple Ray Shareholders who held Purple Ray
Preferred Stock immediately prior to the Effective Time of the Merger (the
"PURPLE RAY PREFERRED SHAREHOLDERS") will be entitled to receive additional
shares of ISSI Common Stock as follows (collectively the "ADDITIONAL MERGER
CONSIDERATION"):

                    (i) an aggregate of 16,483 shares of ISSI Common Stock upon
the completion on or before August 15, 2002 by ISSI of ten (10) fully functional
engineering samples, which do not have to be fully qualified, of the PRSP4000
product, all of which are capable of performing at least 533 million searches
per second (the "SAMPLE CONDITION");

                    (ii) if the Sample Condition is not completed on or before
August 15, 2002, but is completed on or before November 15, 2002, an aggregate
of 8,242 shares of ISSI Common Stock;

                    (iii) an aggregate of 16,483 shares of ISSI Common Stock
upon the delivery on or before November 15, 2002 to ISSI of a letter confirmed
by an agent or employee of ISSI from a responsible manager of a customer or
prospective customer of ISSI stating that such customer has committed a design
intended for production with the PRSP4000 product (the "DESIGN WIN CONDITION");

                    (iv) if the Design Win Condition is not completed on or
before November 15, 2002, but is completed on or before February 15, 2003, an
aggregate of 8,242 shares of ISSI Common Stock;

                    (v) an aggregate of 16,483 shares of ISSI Common Stock upon
recognition on or before February 15, 2003 in accordance with ISSI's internal
accounting policies (which shall conform to United States generally accepted
accounting principles) of cumulative revenue on sales of the PRSP4000 product of
at least $10,000 by ISSI (the "SALES CONDITION," and, collectively with the
Sample Condition and the Design Win Condition, the "CONDITIONS"); and

                    (vi) if the Sales Condition is not completed on or before
February 15, 2003, but is completed on or before May 15, 2003, an aggregate of
8,242 shares of ISSI Common Stock.

                                      -4-


               (b) The aggregate number of shares of ISSI Common Stock that
constitutes the Additional Merger Consideration, if any, shall be delivered to
the Purple Ray Preferred Shareholders as soon as practicable (but no later than
thirty (30) days) after the delivery of the Final Compliance Notice (as defined
below); provided, however, that should there be at such time any dispute as to
whether a Condition was satisfied or not, then such shares of ISSI Common Stock
shall be delivered to the Purple Ray Preferred Shareholders as soon as
practicable (but no later than thirty (30) days) after the final resolution of
all such disputes pursuant to Section 2.5(c). The shares of ISSI Common Stock
that constitutes the Additional Merger Consideration shall be allocated to each
such Purple Ray Preferred Shareholder pro rata based on the number of shares of
Purple Ray Preferred Stock held by such Purple Ray Shareholders immediately
prior to the Effective Time of the Merger.

               (c) The officer or general manger of ISSI (the "ISSI
REPRESENTATIVE") in charge of the division in which the Purple Ray assets are
used and the PRSP4000 product is being developed (the "DIVISION") shall, on or
before 10 days after each deadline for the satisfaction of a Condition described
in Section 2.5(a), deliver to the Agent, or a designee of the Agent who was a
Purple Ray employee immediately prior to the Effective Time of the Merger and
who is then employed by ISSI in such division (the "PURPLE RAY REPRESENTATIVE")
a written notice (the "COMPLIANCE NOTICE") indicating whether such Condition has
been satisfied, and if such Condition has not been satisfied, a brief
description of the criteria that have not been met. Notwithstanding the
foregoing, the final Compliance Notice (the "FINAL COMPLIANCE NOTICE") shall be
delivered on or before 10 days after the earlier of (i) May 15, 2003, or (ii)
the satisfaction of the Sales Condition. Unless otherwise determined by an
arbitration proceeding pursuant to Sections 2.5(d), the determination of the
ISSI Representative shall be the conclusive determination as to whether any
Condition was satisfied for purposes of this Section 2.

               (d) If the Purple Ray Representative does not agree with the
conclusions made in any Compliance Notice, then each of the ISSI Representative
and the Purple Ray Representative shall attempt to resolve the issue in good
faith. If the ISSI Representative and the Purple Ray Representative have not,
within ten (10) business days after the date of the delivery of the Final
Compliance Notice, reached an agreement as to whether a Condition covered in any
Compliance Notice was satisfied on or before the applicable deadline described
in Section 2.5(a), then the Purple Ray Representative may demand in writing on
or before twenty (20) business days after the date of the delivery of the Final
Compliance Notice that the issue of whether such Condition has been satisfied be
settled by arbitration conducted by three (3) arbitrators. For any such
arbitration, ISSI and the Agent shall each select one (1) arbitrator, and the
two (2) arbitrators so selected shall select a third arbitrator. The arbitrators
shall, within ten (10) business days after the last day of any hearings on any
motion, issue a definitive ruling on such motion. The arbitrators shall also,
within twenty (20) business days from the last day of any hearings, issue a
definitive ruling on the imposition of any such sanctions or the issuance of any
such award in such arbitration. The arbitrators shall also establish procedures
designed to reduce the cost and time for discovery while allowing the parties an
opportunity, adequate in the sole judgment of the arbitrators, to discover
relevant information from the opposing parties about the subject matter of the
dispute. The arbitrators shall rule upon motions to compel or limit discovery
and shall have the authority to impose sanctions, including attorneys fees and
costs, to the same extent as a court of competent law or equity, should the
arbitrators

                                      -5-


determine that discovery was sought without substantial justification or that
discovery was refused or objected to without substantial justification. The
decision of a majority of the three (3) arbitrators shall be binding and
conclusive upon the parties to this Agreement. Such decision shall be written
and shall be supported by written findings of fact and conclusions that shall
set forth the award, judgment, decree or order awarded by the arbitrators.

               (e) Notwithstanding any provision of this Section 2.5, if the
satisfaction of any Condition is delayed as a direct result of a fire,
earthquake, general strike, significant power outage, government restriction,
act of God or act of war or insurrection, then the deadline for such Condition
shall be delayed for a period of time equal to the period of time from the date
of such event to the date in which the Division is first reasonably able to
resume pursuit of the Condition.

               (f) ISSI agrees to use all commercially reasonable efforts
consistent with the goal of achieving the Conditions to provide commercially
reasonable resources and to permit commercially reasonable focus on achieving
the Conditions, and further agrees not to make operational or other decisions
with respect to the PRSP4000 product for the purpose of decreasing the
Additional Merger Consideration.

     3.   Effect of Merger; Exchange of Certificates.

          3.1 Conversion of Purple Ray Capital Stock. As of the Effective Time
of the Merger, each share of Purple Ray Capital Stock that is issued and
outstanding immediately prior to the Effective Time of the Merger (other than
shares, if any, held by persons exercising dissenters' rights in accordance with
Chapter 13 of the CCL ("DISSENTING SHARES") as provided for in Section 3.3
below), shall, by virtue of the Merger and without any action on the part of
Purple Ray Shareholders, be converted into shares of ISSI Common Stock as
follows: (i) each share of Purple Ray Common Stock issued and outstanding
immediately prior to the Effective Time of the Merger will be converted into
0.03266 (the "COMMON STOCK CONVERSION RATIO") shares of the ISSI Common Stock,
and (ii) each share of Purple Ray Preferred Stock issued and outstanding
immediately prior to the Effective Time of the Merger will be converted into
0.04250 (the "PREFERRED STOCK CONVERSION RATIO") shares of ISSI Common Stock
(the consideration to be paid pursuant to (i) and (ii) above is hereinafter
referred to as the "MERGER CONSIDERATION"). The Common Stock Conversion Ratio
and the Preferred Stock Conversion Ratio will be adjusted as appropriate to give
effect to any reclassification, stock split, reverse split, stock dividend
(including any dividend or distribution of securities convertible into ISSI
Common Stock), reorganization, recapitalization or other like change with
respect to ISSI Common Stock occurring after the date hereof and prior to the
Effective Time of the Merger.

          3.2 Assumption of Options. At the Effective Time of the Merger, each
Purple Ray Option outstanding shall be assumed by ISSI and be converted into an
Option to purchase ISSI Common Stock. Each Purple Ray Option so assumed by ISSI
under this Agreement shall continue to have, and be subject to, the same terms
and conditions, including vesting, set forth in the Purple Ray, Inc. 2000 Stock
Plan (the "PLAN") and the option agreement applicable to such Purple Ray Option,
except that (i) such assumed Purple Ray Option will be exercisable for that
number of whole shares of ISSI Common Stock equal to the product of the number
of shares of Purple Ray Common

                                      -6-


Stock that were issuable upon exercise of such Purple Ray Option immediately
prior to the Effective Time of the Merger multiplied by 0.03266 (the "OPTION
CONVERSION RATIO"), rounded down to the nearest whole number of shares of ISSI
Common Stock, and (ii) the per share exercise price for the shares of ISSI
Common Stock issuable upon exercise of such assumed or replaced Purple Ray
Option shall be equal to the quotient obtained by dividing the exercise price
per share of Purple Ray Common Stock at which such assumed Purple Ray Option was
exercisable immediately prior to the Effective Time of the Merger by the Option
Conversion Ratio, rounded up to the nearest whole cent.

          3.3 Dissenters' Rights. If holders of Purple Ray Capital Stock are
entitled to dissenters' rights at the Effective Time of the Merger under Section
1300 et seq. of the CCC, the shares as to which dissenters' rights are available
("DISSENTING SHARES") shall not be converted into the Merger Consideration on or
after the Effective Time of the Merger, but shall instead be converted into the
right to receive from the Surviving Corporation such consideration as may be
determined to be due with respect to such Dissenting Shares pursuant to the CCC.
Each holder of Dissenting Shares (a "DISSENTING SHAREHOLDER") who, pursuant to
the provisions of Section 1300 et seq. of the CCC, becomes entitled to payment
of the value of shares of Purple Ray Capital Stock held by such Dissenting
Shareholder shall receive payment therefor (but only after the value therefor
shall have been agreed upon or finally determined pursuant to such provisions).
In the event of the legal obligation, after the Effective Time of the Merger, to
deliver the Merger Consideration to any Dissenting Shareholder who shall have
failed to make an effective demand for appraisal or shall have lost his status
as a Dissenting Shareholder, ISSI shall issue and deliver, upon surrender by
such Dissenting Shareholder of his certificate or certificates representing
shares of Purple Ray Capital Stock, the Merger Consideration to which such
Dissenting Shareholder is then entitled under this Section 3.3 and Section 1300
et seq. of the CCC.

          3.4 Fractional Shares. No fractional shares of ISSI Common Stock shall
be issued in the Merger. In lieu thereof, each holder of shares of Purple Ray
Capital Stock who would otherwise be entitled to receive a fraction of a share
of ISSI Common Stock shall receive from ISSI an amount of cash (rounded to the
nearest whole cent) equal to the product of the fraction of a share of ISSI
Common Stock to which such holder would otherwise be entitled, multiplied by the
average closing price per share for the ISSI Common Stock for the ten
consecutive trading days ending on and including the Effective Date of the
Merger. For the purpose of determining fractional shares with respect to each
Purple Ray Shareholder, all shares of ISSI Common Stock to be issued to such
Purple Ray Shareholder as a result of the conversion of Purple Ray Capital Stock
at the Effective Time of the Merger shall be aggregated.

          3.5 Exchange of Certificates.

               (a) Exchange Agent. Prior to the Closing Date, ISSI shall appoint
itself or Mellon Shareholder Services, L.L.C. to act as the exchange agent (the
"EXCHANGE AGENT") in the Merger.

               (b) ISSI to Provide ISSI Common Stock. Promptly after the
Effective Date of the Merger, ISSI shall make available for exchange in
accordance with this Section 3.5, through such reasonable procedures as ISSI may
adopt that are not inconsistent with this Agreement, the shares of

                                      -7-


ISSI Common Stock issuable pursuant to Section 3.1 in exchange for outstanding
shares of Purple Ray Capital Stock.

               (c) Exchange Procedures. As soon as practicable, but no later
than thirty (30) days after the Effective Date of the Merger, the Exchange Agent
shall mail to each holder of record of a certificate or certificates which
immediately prior to the Effective Date of the Merger represented outstanding
shares of Purple Ray Capital Stock (the "CERTIFICATES") whose shares are being
converted into the Merger Consideration pursuant to Section 3.1 hereof (less any
shares held in escrow pursuant to Section 3.7 hereof), (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and which shall be in such form and have such
other provisions as ISSI may reasonably specify, including appropriate
investment representations to be made by each such shareholder) (the "LETTER OF
TRANSMITTAL") and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for the Merger Consideration (less any shares held in
escrow pursuant to Section 3.7 hereof). Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by ISSI, together with such letter of transmittal, duly executed, the
holder of such Certificate shall be entitled to receive in exchange therefor the
number of shares of ISSI Common Stock (less any shares held in escrow pursuant
to Section 3.7 hereof) to which the holder of Purple Ray Capital Stock is
entitled pursuant to Section 3.1 hereof. The Certificate so surrendered shall
forthwith be canceled. No interest will accrue or be paid to the holder of any
outstanding Purple Ray Capital Stock. From and after the Effective Date of the
Merger, until surrendered as contemplated by this Section 3.5(c), each
Certificate shall be deemed for all corporate purposes to evidence the number of
shares of ISSI Common Stock into which the shares of Purple Ray Capital Stock
represented by such Certificate have been converted. Notwithstanding the
foregoing procedures, ISSI shall use its reasonable efforts to provide the form
of Letter of Transmittal to Purple Ray as soon as practical after the date
hereof, and Purple Ray shall provide such Letter of Transmittal to each Purple
Ray Shareholder. The parties agree that the Exchange Agent shall not be
obligated to mail such Letter of Transmittal to any Purple Ray Shareholders to
whom Purple Ray provided the Letter of Transmittal prior to Closing. ISSI agrees
that to the extent a Purple Ray Shareholder provides a fully executed and
completed Letter of Transmittal together with the related Certificates held by
such shareholder to ISSI at least five (5) business days prior to the Closing,
then ISSI will use its reasonable best efforts to provide to such Purple Ray
Shareholder at the Closing, or as soon as practicable thereafter, a certificate
representing the shares of ISSI Common Stock to which such shareholder is
entitled pursuant to the terms hereof.

               (d) No Further Ownership Rights in Capital Stock of Purple Ray.
The Merger Consideration delivered upon the surrender for exchange of shares of
Purple Ray Capital Stock in accordance with the terms hereof shall be deemed to
have been delivered in full satisfaction of all rights pertaining to such Purple
Ray Capital Stock. There shall be no further registration of transfers on the
stock transfer books of the Surviving Corporation of Purple Ray Capital Stock
which were outstanding immediately prior to the Effective Date of the Merger.
If, after the Effective Date of the Merger, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in this Section 3.5, provided that the presenting holder is listed on
Purple Ray's shareholder list as a holder of Purple Ray Common Stock.

                                      -8-


          3.6 Taking of Necessary Action; Further Action. ISSI and Purple Ray
shall take all such actions as may be necessary or appropriate in order to
effect the Merger as promptly as possible. If, at any time after the Effective
Date of the Merger, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Purple Ray, the officers and directors of the Surviving
Corporation are fully authorized in the name of the Surviving Corporation or
otherwise to take, and shall take, all such action.

          3.7 Escrow Agreement. The parties hereto agree that 16,483 shares of
the shares of ISSI Common Stock to be issued to the Purple Ray Preferred
Shareholders in the Merger and 3,539 shares of the shares of ISSI Common Stock
to be issued to the holders of Purple Ray Common Stock immediately prior to the
Effective Time of the Merger (the "PURPLE RAY COMMON SHAREHOLDERS") (all of such
share, collectively, the "ESCROW AMOUNT") shall be held in escrow pursuant to
the terms of an escrow agreement in substantially the form attached hereto as
Exhibit B (the "ESCROW AGREEMENT"). Notwithstanding anything to the contrary in
this Agreement, no Purple Ray Shareholder shall receive certificates for any
shares of ISSI Common Stock held in escrow unless and until permitted under the
terms of the Escrow Agreement.

          3.8 Lost Certificates. If any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
ISSI or the Exchange Agent, the posting by such person of a bond in such
reasonable amount as ISSI or the Exchange Agent may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the shares of ISSI Common Stock, cash in lieu of fractional shares,
if any, and unpaid dividends and distributions, if any, on shares of ISSI Common
Stock deliverable in respect thereof pursuant to Section 3 of this Agreement.

     4.   Securities Act Compliance.

          4.1 Securities Act Exemption. The issuance of the ISSI Common Stock in
the Merger shall not be registered under the Securities Act of 1933, as amended
(the "SECURITIES ACT"), in reliance upon Section 4(2) and/or Rule 506 under
Regulation D of the Securities Act.

          4.2 Securities Restrictions. The certificates representing the shares
of ISSI Common Stock issued pursuant to this Agreement shall bear a restrictive
legend (and stop transfer orders shall be placed against the transfer thereof
with ISSI's transfer agent), stating substantially as follows:

               "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
               SHARES MAY NOT BE SOLD, OFFERED FOR SALE, TRANSFERRED, ASSIGNED
               OR OTHERWISE DISPOSED OF EXCEPT (I) PURSUANT TO AN EFFECTIVE
               REGISTRATION STATEMENT RELATED THERETO, (II) IN COMPLIANCE WITH
               RULE 144 OR (III) PURSUANT TO AN OPINION OF COUNSEL FOR ISSI THAT

                                      -9-


               SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
               1933."

     5.   Representations and Warranties of Purple Ray. Purple Ray represents
and warrants to ISSI that the statements contained in this Section 5 are correct
and complete as of the date of this Agreement, except as set forth in the
disclosure schedule delivered by Purple Ray to ISSI on the date hereof (and
initialed by ISSI), a copy of which is attached hereto as Exhibit C (referred to
herein as the "PURPLE RAY DISCLOSURE SCHEDULE"). The Purple Ray Disclosure
Schedule will be arranged in paragraphs corresponding to the lettered and
numbered paragraphs contained in this Section 5.

          5.1 Organization, Qualification, and Corporate Power. Purple Ray is a
corporation duly organized, validly existing, and in good standing under the
laws of the State of California. Purple Ray is duly authorized to conduct
business and is in good standing under the laws of each other jurisdiction where
the failure to obtain such qualification would be reasonably likely to result in
a Material Adverse Effect. There is no state, other than California, in which
Purple Ray owns any property or in which it has any employees, offices or
operations. Purple Ray has full corporate power and authority, and has all
necessary licenses and permits, to carry on the businesses in which it is
engaged and to own and use the properties owned and used by it. Section 5.1 of
the Purple Ray Disclosure Schedule lists the directors and officers of Purple
Ray. The operations now being conducted by Purple Ray are not now and have never
been conducted under any other name. Purple Ray has delivered to ISSI a true,
correct and complete copy of the Articles of Incorporation and Bylaws or other
charter documents, as applicable, of Purple Ray, each as amended to date.

          5.2 Authorization. Purple Ray has full corporate power and authority
to execute and deliver this Agreement, the Certificate of Merger, and any other
agreements or documents executed by Purple Ray pursuant to this Agreement or the
Merger (the "PURPLE RAY RELATED AGREEMENTS"), and subject to receipt of the
requisite approval of its shareholders, to consummate the transactions
contemplated hereunder and to perform its obligations hereunder and no other
proceedings on the part of Purple Ray are necessary to authorize the execution,
delivery and performance of this Agreement. This Agreement and the transactions
contemplated hereby have been approved by the unanimous vote of Purple Ray's
Board of Directors. Each of this Agreement, the Certificate of Merger and the
Purple Ray Related Agreements, constitutes the valid and legally binding
obligation of Purple Ray, enforceable against Purple Ray in accordance with
their respective terms and conditions, subject to the effect of (i) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to rights of creditors generally and (ii) rules of
law and equity governing specific performance, injunctive relief and other
equitable remedies. Purple Ray need not give any notice to, make any filing
with, or obtain any authorization, consent, or approval of any government or
governmental agency in order to consummate the transactions contemplated by this
Agreement.

               (a) Capital Stock. As of the date of this Agreement, the entire
authorized capital stock of Purple Ray consists of 33,000,000 shares of Purple
Ray Capital Stock, consisting of 25,000,000 shares of Purple Ray Common Stock,
7,642,000 of which are issued and outstanding,

                                      -10-


and 8,000,000 shares of Purple Ray Preferred Stock, all of which are designated
Series A Preferred Stock, 6,570,000 shares of which are issued and outstanding.
All of the issued and outstanding shares of capital stock have been duly
authorized, are validly issued, fully paid, and non-assessable, are free of any
liens or encumbrances and are held of record by the respective shareholders as
set forth in Section 5.3(a) of the Purple Ray Disclosure Schedule. All of the
outstanding shares of capital stock have been offered, issued and sold by Purple
Ray in compliance with applicable Federal and state securities laws. These are
no declared or accrued but unpaid dividends with respect to any shares of Purple
Ray Capital Stock.

               (b) No Other Rights or Agreements. Section 5.3(b) of the Purple
Ray Disclosure Schedule lists all of the holders, as of the date of this
Agreement, of options, warrants, purchase rights, subscription rights,
conversion rights, exchange rights and other rights that could require Purple
Ray to issue, sell or otherwise cause to become outstanding any of its capital
stock (the "STOCK RIGHTS"), and the number of shares of Purple Ray Common Stock
subject to such Stock Rights. For each such holder, Section 5.3(b) of the Purple
Ray Disclosure Schedule lists for each such Stock Right the applicable exercise
price or conversion ratio, the date of grant or issuance, the vesting schedule,
if any, the number of shares of Purple Ray Common Stock or Purple Ray Preferred
Stock that are vested as of the date of this Agreement, and, if an option
granted under the Purple Ray, Inc. 2000 Stock Plan, whether such option is
intended to qualify as an incentive stock option as defined in Section 422 of
the Code. Except as set forth in Section 5.3(b) of the Purple Ray Disclosure
Schedule, there are no other outstanding or authorized Stock Rights. There are
no outstanding or authorized stock appreciation, phantom stock, profit
participation, or similar rights with respect to Purple Ray. There are no voting
trusts, proxies, or other agreements or understandings with respect to the
voting of the capital stock of Purple Ray.

          5.4 Noncontravention. Except as set forth in Section 5.4 of the Purple
Ray Disclosure Schedule, neither the execution and the delivery of this
Agreement by Purple Ray nor the consummation by Purple Ray of the transactions
contemplated hereby, will (A) violate any constitution, statute, regulation,
rule, injunction, judgment, order, decree, ruling, charge, or other restriction
of any government, governmental agency, or court to which Purple Ray is subject
or any provision of its Articles of Incorporation or bylaws, or (B) (i) conflict
with, (ii) result in a breach of, (iii) constitute a default under, (iv) result
in the acceleration of, (v) create in any party the right to accelerate,

assets is subject (or result in the imposition of any Security Interest upon any
of its assets).

          5.5 Fees. Purple Ray has no liability or obligation to pay any fees or
commissions to any broker, finder, agent or attorney with respect to the
transactions contemplated by this Agreement.

          5.6 Financial Statements. Section 5.6 of the Purple Ray Disclosure
Schedule contains the unaudited balance sheets and statements of income and cash
flow as of and for the fiscal years ended December 31, 2000 and 2001 for Purple
Ray (collectively the "FINANCIAL STATEMENTS"). The Financial Statements
(including the notes thereto) are true and correct and have been prepared on a

                                      -11-


consistent basis throughout the periods covered thereby. The Financial
Statements present fairly the financial condition of Purple Ray as of such dates
and the results of operations of Purple Ray for such periods. The books of
account of Purple Ray reflect as of the dates shown thereon all items of income
and expenses, and all assets, liabilities and accruals of Purple Ray required to
be reflected therein in order to accurately represent the financial condition of
Purple Ray in all material respects.

          5.7 Subsidiaries. Purple Ray has no subsidiaries and has not been a

leasehold interest in, the properties and assets (including, without limitation,
all Intellectual Property) used by it, located on its premises, or shown on the
balance sheet dated as of December 31, 2001 contained within the Financial
Statements (the "MOST RECENT BALANCE SHEET") or acquired after the date thereof,
free and clear of all Security Interests. No Person other than Purple Ray will
own at the time of the Closing any assets or properties currently utilized in or
necessary to the operations or business of Purple Ray or situated on any of the
premises of Purple Ray. There are no existing contracts, agreements, commitments
or arrangements with any Person to acquire any of the assets or properties of
Purple Ray (or any interest therein) except for this Agreement.

          5.11 Legal Compliance. Purple Ray has complied in all material
respects with all applicable laws (including rules, regulations, codes, plans,
injunctions, judgments, orders, decrees, rulings, and charges thereunder) of
federal, state, local, and foreign governments (and all agencies thereof). No
action, suit, proceeding, hearing, investigation, charge, complaint, claim,
demand, notice or inquiry has been filed or commenced against, or received by,
any governmental body alleging any failure to so comply. Purple Ray has all
licenses, permits, approvals, registrations, qualifications, certificates and
other governmental authorizations that are necessary for the operations of
Purple Ray as they are presently conducted, except for such licenses, permits,
approvals, registrations, qualifications, certificates and other governmental
authorizations the absence of which, individually or in the aggregate, have not
resulted in, and are not reasonably likely to result in, a Material Adverse
Effect.

          5.12 Tax Matters.

               (a) For purposes of this Agreement, "TAXES" means all federal,
state, municipal, local or foreign income, gross receipts, windfall profits,
severance, property, production, sales, use, value added, license, excise,
franchise, employment, withholding, capital stock, levies, imposts, duties,
transfer and registration fees or similar taxes or charges imposed on the
income, payroll, properties or operations of Purple Ray, together with any
interest, additions or penalties, deficiencies or assessments with respect
thereto and any interest in respect of such additions or penalties.

               (b) Purple Ray has filed all reports and returns with respect to
any Taxes ("TAX RETURNS") that it was required to file. All such Tax Returns
were correct and complete in all respects, except for any errors or omissions
that are not, individually or in the aggregate, reasonably likely to have a
Material Adverse Effect on Purple Ray, and no such Tax Returns are currently the
subject of audit. All Taxes owed by Purple Ray (whether or not shown on any Tax
Return) were paid in full when due or are being contested in good faith and are
supported by adequate reserves on the Most Recent Balance Sheet. Purple Ray has
provided adequate reserves on its Financial Statements for the payment of any
taxes accrued but not yet due and payable. Purple Ray is not currently the
beneficiary of any extension of time within which to file any Tax Return, and
Purple Ray has not waived any statute of limitations in respect of Taxes or
agreed to any extension of time with respect to any Tax assessment or
deficiency.

               (c) There is no dispute or claim concerning any Tax liability of
Purple Ray either (A) claimed or raised by any authority in writing or (B) based
upon personal contact with any agent of such authority. There are no tax liens
of any kind upon any property or assets of Purple Ray, except for inchoate liens
for taxes not yet due and payable.

               (d) Purple Ray has not filed a consent under Sec. 341(f) of the
Internal Revenue Code of 1986, as amended (the "CODE") concerning collapsible
corporations. Purple Ray has not made any payments, is not obligated to make any
payments, and is not a party to any agreement that under any circumstances could
obligate it to make any payments as a result of the consummation of the Merger
that will not be deductible under Code Sec. 280G. Purple Ray has not been a
United States real property holding corporation within the meaning of Code Sec.
897(c)(2)

                                      -15-


during the applicable period specified in Code Sec. 897(c)(1)(A)(ii). Purple Ray
is not a party to any tax allocation or sharing agreement. Purple Ray (A) has
not been a member of any affiliated group within the meaning of Code Sec. 1504
or any similar group defined under a similar provision of state, local, or
foreign law (an "AFFILIATED GROUP") filing a consolidated federal Income Tax
Return (other than a group the common parent of which was Purple Ray) and (B)
has no any liability for the taxes of any Person (other than any of Purple Ray)
under Treas. Reg. Section 1.1502-6 (or any similar provision of state, local, or
foreign law), as a transferee or successor, by contract, or otherwise.

               (e) The unpaid Taxes of Purple Ray (A) did not, as of the Most
Recent Fiscal Year End, exceed by any amount the reserve for Tax liability
(other than any reserve for deferred taxes established to reflect timing
differences between book and tax income) set forth on the face of the Most
Recent Balance Sheet (rather than in any notes thereto) and (B) will not exceed
that reserve as adjusted for operations and transactions through the Closing
Date in accordance with the past custom and practice of Purple Ray in filing its
Tax Returns.

business by the employees of Purple Ray, nor the conduct of Purple Ray's
business as presently proposed, will, to Purple Ray's Knowledge, conflict with
or result in a breach of the terms, conditions or provisions of, or constitute a

                    (i) Each such Employee Benefit Plan (and each related trust,

Revenue Service is deemed to have approved the form of such Plan under
applicable IRS Revenue Procedures. A copy of such determination letters have
been provided to ISSI and nothing has occurred since the date of each such
determination letter that would cause such Employee Pension Benefit Plan to lose

Benefit Plan. The terms of any such documentation or other communication do not
prohibit ISSI from amending or terminating any such Employee Benefit Plan.

ever has been required to contribute:

                    (i) There have been no prohibited transactions within the
meaning of ERISA Sec 406 and Code Sec. 4975 with respect to any such Employee
Benefit Plan. No fiduciary within the meaning of ERISA Sec. 3(21) (a
"FIDUCIARY"), has any liability for breach of fiduciary duty or any other
failure to act or comply in connection with the administration or investment of
the assets of any such Employee Benefit Plan. No action, suit, proceeding,
hearing, or investigation with respect to the administration or the investment
of the assets of any such Employee Benefit Plan (other than routine claims for

               (d) There is no liability in connection with any Employee Benefit
Plan that is not fully disclosed or provided for on the Most Recent Balance
Sheet for which disclosure would be required under generally accepted accounting
principles.

               (e) No Employee Benefit Plan of Purple Ray has any liability to
any plan participant, beneficiary or other person by reason of the payment of
benefits or the failure to pay benefits with respect to benefits under or in
connection with any such Employee Benefit Plan, other than claims in the normal
administration of such plans.

the event and for so long as any Party actively is contesting or defending
against any action, suit, proceeding, hearing, investigation, charge, complaint,
claim, or demand in connection with (i) any transaction contemplated under this
Agreement or (ii) any fact, situation, circumstance, status, condition,
activity, practice, plan, occurrence, event, incident, action, failure to act,
or transaction (A) on or prior to the Effective Time of the Merger involving
Purple Ray or (B) arising out of ISSI's operation of the business of the
Surviving Corporation following the Effective Time of the Merger in the manner
in which it is presently conducted and planned to be conducted, each of the
other Parties will cooperate with the party, its counsel in the contest or
defense, make available their personnel, and provide such testimony and access
to their books and records as shall be reasonably necessary in connection with

          8.3 Transition. None of the officers or directors of Purple Ray will
take any action that is designed or intended to have the effect of discouraging
any lessor, licensor, customer, supplier, or other business associate of Purple
Ray from maintaining the same business relationships

                                      -31-


with the Surviving Corporation after the Effective Time of the Merger as it
maintained with Purple Ray prior to the Effective Time of the Merger.

          8.4 Confidentiality. Each of the parties hereto hereby agrees to keep
such information or knowledge obtained in any due diligence or other
investigation pursuant to the negotiation and execution of this Agreement or the
effectuation of the transactions contemplated hereby, confidential, except to
the extent that such information is or becomes publicly known or available or is
independently acquired or developed. In this regard, Purple Ray acknowledges
that ISSI's Common Stock is publicly traded and that any information obtained
during the course of its due diligence could be considered to be material
non-public information within the meaning of federal and state securities laws.
Accordingly, Purple Ray agrees not to, and agrees to advise its shareholders,
employees and agents not to, engage in any transactions in ISSI's Common Stock
in violation of applicable insider trading laws.

          8.5 Purple Ray Employees. All employees of Purple Ray immediately
prior to the Effective Time of the Merger shall become employees of ISSI or the
Surviving Corporation following the Effective Time of the Merger and will be

               (a) On or before the Closing Date, Purple Ray and each holder of
a Purple Ray Option that is then an employee of Purple Ray shall enter into a
written agreement pursuant to which the shares of Purple Ray Common Stock that
may be purchased upon exercise of such Purple Ray Option that are then unvested
shall thereafter vest pursuant to vesting provisions that are the same as the
vesting provisions included in the Restricted Stock Purchase Agreement attached
hereto as Exhibit F-2 (an "OPTION MODIFICATION AGREEMENT").

               (b) At the Effective Time of the Merger, each Purple Ray Option
outstanding shall be assumed by ISSI and be converted into an option to purchase
ISSI Common Stock in accordance with Section 3.2 of this Agreement. Consistent
with the terms of the Plan and the documents governing the outstanding options
under the Plan, the Merger will not terminate any of the outstanding Purple Ray
Options under the Plan or accelerate the exercisability or vesting of such
options or the shares of ISSI Common Stock which will be subject to those
options upon ISSI's assumption of the Purple Ray Options in the Merger. ISSI
shall take all corporate action necessary for the assumption of the Plan,
including the reservation for issuance of a sufficient number of shares of ISSI
Common Stock for delivery under the Plan assumed in accordance with this Section
8.6. It is the intention of the parties that the options so assumed by ISSI
qualify, to the maximum extent permissible, following the Effective Time of the
Merger as incentive stock options as defined in Section 422 of the Code to the
extent such options qualified as incentive stock options prior to the Effective
Time of the Merger. As soon as practicable after the Effective Time of the
Merger, ISSI will issue to each person who, immediately prior to the Effective
Time of the Merger, was a holder of an outstanding Purple Ray Non-Employee
Option under the Plan a document evidencing the foregoing assumption of such
option by ISSI.

to the fullest extent permitted by law, for a period of six years from the
Effective Time of the Merger, honor all of Purple Ray's obligations under its
Articles of Incorporation or the CCC to indemnify and hold harmless each present
and former director and officer of Purple Ray (the "INDEMNIFIED PARTIES"),
against any costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages, liabilities or amounts paid in settlement
incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of or pertaining to matters existing or occurring at or prior to the

          8.11 Securities Law Exemption; Information Statement. Purple Ray shall
as soon as practicable after the date of this Agreement conduct a reasonable
inquiry of each of the Purple Ray Shareholders for the purpose of determining
whether such Purple Ray Shareholder is an accredited investor within the meaning
of Regulation D under the Act, and shall report the results of such inquiry to
ISSI. If ISSI is unable to form a reasonable belief that all of the Purple Ray
Shareholders are accredited investors, then ISSI and Purple Ray shall prepare an
information statement (the "INFORMATION STATEMENT") to be distributed to the
Purple Ray Shareholders, which shall constitute a disclosure document for the
offer and issuance of the shares of ISSI Common Stock to be received by the
holders of the Purple Ray Capital Stock. Each of ISSI and Purple Ray shall use
all their reasonable efforts to cause the Information Statement to comply with
applicable federal and state securities laws, including Regulation D promulgated

regarding Purple Ray and ISSI, the terms of this Agreement and the Merger and
the unanimous recommendation of the Board of Directors of Purple Ray in favor of
this Agreement and the Merger. Each of ISSI and Purple Ray agrees to provide
promptly to the other such information concerning its business and financial
statements and affairs as, in the reasonable judgment of the providing party or
its counsel, may be required or appropriate for including in the Information
Statement, or in any amendment or supplements thereto, and to cause its counsel
to cooperate with the other's counsel and auditors in preparation of the
Information Statement. ISSI will promptly advise Purple Ray, and Purple Ray will
promptly advise ISSI, in writing if at any time prior to the Effective Time of
the Merger such party shall obtain knowledge of any facts that might make it
necessary or appropriate to amend or supplement the Information Statement in
order to make statements contained or incorporated by reference therein not
misleading or to comply with applicable law.

          8.12 Tax Return Preparation. To the extent not completed by Purple Ray
on or before the Closing, ISSI shall file the federal income tax returns for
Purple Ray for the year ended December 31, 2001 and for the stub period ending
on the Effective Date of the Merger. The cumulative expenses incurred by Purple
Ray or ISSI for the preparation of the federal income tax returns for Purple Ray
for the year ended December 31, 2001 and for the stub period ending on the
Effective Date of the Merger that exceed $5,000 shall constitute a claim against

representations and warranties of Purple Ray in this Agreement or in any

period of twelve (12) months from the Effective Time of the Merger. Following
the Effective Time of the Merger, the remedies of ISSI for breach of any of the

performed prior to the Effective Time of the Merger, and all representations and
warranties of ISSI in this Agreement or in any instrument delivered pursuant to

the Effective Time of the Merger.

          10.2 Escrow Arrangements.

               (a) Escrow Fund. As soon as practicable after the Effective Time
of the Merger, shares of ISSI Common Stock which comprise the Escrow Amount,
without any act of any

                                      -37-


Purple Ray Shareholder, will be deposited with an escrow agent mutually agreed
to by ISSI and Purple Ray as Escrow Agent (the "ESCROW AGENT"), such deposit to
constitute an escrow fund (the "ESCROW FUND") to be governed by the terms set
forth herein and at a cost and expense to be borne by ISSI. The shares of ISSI
Common Stock included in the Escrow Fund shall not have any repurchase rights in
favor of any Person or any restrictions on transferability. Each of the Purple
Ray Preferred Shareholders shall contribute to the Escrow Fund their pro rata
share, based on their percentage ownership of the Purple Ray Preferred Stock
outstanding at the Effective Time of the Merger, of the 16,483 shares of ISSI
Common Stock that are contributed to the Escrow Fund by the Purple Ray Preferred
Shareholders. Each of the Purple Ray Common Shareholders shall contribute to the
Escrow Fund their pro rata share, based on their percentage ownership of the
Purple Ray Common Stock outstanding at the Effective Time of the Merger, of the
3,539 shares of ISSI Common Stock that are contributed to the Escrow Fund by the
Purple Ray Common Shareholders. The Escrow Agent shall not be responsible for
confirming that the shares contributed to the Escrow Fund comprise the Escrow
Amount or that the portion contributed on behalf of each holder of Purple Ray
Capital Stock is in the proper proportion.

               (b) Indemnification. The shareholders of Purple Ray shall (pro
rata in accordance with their interest in the Escrow Fund) indemnify and hold
harmless ISSI and each of its Affiliates from and against, and the Escrow Fund
shall be available to compensate ISSI and each of its Affiliates for, any and
all actions, suits, proceedings, hearings, investigations, charges, complaints,
claims, demands, injunctions, judgments, orders, decrees, rulings, damages,
dues, penalties, fines, costs, reasonable amounts paid in settlement,
liabilities, obligations, taxes, liens, losses, expenses, and fees, including
court costs and reasonable attorneys' fees and expenses in connection with any
action, suit or proceeding to the extent of the amount of such actions, suits,
proceedings, hearings, investigations, charges, complaints, claims, demands,
injunctions, judgments, orders, decrees, rulings, damages, dues, penalties,
fines, costs, reasonable amounts paid in settlement, liabilities, obligations,
taxes, liens, losses, expenses or fees (collectively "LOSSES") that ISSI or any
of its Affiliates has incurred by reason of the breach by Purple Ray of any
representation, warranty, covenant or agreement of Purple Ray contained herein
(including the Purple Ray Disclosure Schedule), or by reason of any
misrepresentation by Purple Ray made herein (including the Purple Ray Disclosure
Schedule). After the Closing, resort to the Escrow Fund shall be the exclusive
contractual remedy of ISSI and its Affiliates against Purple Ray or any of its
directors, officers, representatives, agents or shareholders for any such
breaches and misrepresentations; provided, however, that nothing herein shall
limit any remedy for Losses incurred as a result of fraud. Notwithstanding the
foregoing, and except for a claim arising under Sections 8.12 and 11.3(a), ISSI
may not receive any amounts from the Escrow Fund unless and until Officer's
Certificates (as defined in Section 10.2(e) below) identifying Losses, the
aggregate amount of which exceed $50,000, have been delivered to the Escrow
Agent as provided in Section 10.2(e) (and any dispute as to such Losses has been
resolved in ISSI's favor). In such case ISSI may thereafter recover from the
Escrow Fund the total of its Losses, including the first $50,000.

               (c) Escrow Period; Distribution upon Termination of Escrow
Periods. Subject to the following requirements, the Escrow Fund shall remain in
existence during the period following the Closing for twelve (12) months (the
"ESCROW PERIOD"). At the expiration of the Escrow Period a portion of the Escrow
Fund shall be released from Escrow to the appropriate

                                      -38-


persons who, prior to the Merger, were shareholders of Purple Ray, in an amount
equal to the initial Escrow Fund less an amount equal to the sum of (i) all
amounts theretofore distributed out of the Escrow Fund to ISSI and its
Affiliates pursuant to this Section 10, (ii) an amount equal to such portion of
the Escrow Fund which, in the reasonable judgment of ISSI, based on the dollar
amount of any unsatisfied claims specified in any Officer's Certificate (as
defined below) theretofore delivered to the Escrow Agent prior to the end of the
Escrow Period and the Fair Market Value of the ISSI Common Stock under Section
10.2(e)(iv) hereof, subject to the objection of the Agent (as defined below) and
the subsequent arbitration of the matter in the manner provided in Section
10.2(g) hereof, is necessary to satisfy such unsatisfied claims, which amount
shall remain in the Escrow Fund (and the Escrow Fund shall remain in existence)
until such claims have been resolved, and (iii) to pay expenses as provided in
the Escrow Agreement. As soon as all such claims have been resolved (such
resolution to be evidenced by the written agreement of ISSI and Agent (as
defined below) or the written decision of the arbitrators as described in
Section 10.2(g)), the Escrow Agent shall deliver to the appropriate persons who,
prior to the Merger, were shareholders of Purple Ray the remaining portion of
the Escrow Fund not required to satisfy such claims. Deliveries of Escrow
Amounts to the shareholders of Purple Ray pursuant to this Section 10.2(c) and
Section 10.2(e)(ii) shall be made in proportion to their respective original
contributions to the Escrow Fund, as calculated by the Agent (as defined below).

               (d) Protection of Escrow Fund. The Escrow Agent shall hold and
safeguard the Escrow Fund during the Escrow Period, shall treat such fund as a
trust fund in accordance with the terms of this Agreement and not as the
property of ISSI and shall hold and dispose of the Escrow Fund only in
accordance with the terms hereof.

               (e) Distributions; Voting; Claims Upon Escrow Fund.

                    (i) Any shares of ISSI Common Stock or other equity
securities issued or distributed by ISSI (including shares issued upon a stock
split) ("NEW SHARES") in respect of ISSI Common Stock in the Escrow Fund which
have not been released from the Escrow Fund, shall be added to the Escrow Fund
and become a part thereof. Any cash dividends paid on ISSI Common Stock in the
Escrow Fund, shall be paid to the persons who, prior to the Merger, were
shareholders of Purple Ray in accordance with their respective contributions to
the Escrow Fund. New Shares and cash dividends issued in respect of shares of
ISSI Common Stock which have been released from the Escrow Fund shall not be
added to the Escrow Fund, but shall be distributed to the record holders
thereof.

                    (ii) Each person who, prior to the Merger was a shareholder
of Purple Ray shall have voting rights with respect to the shares of ISSI Common
Stock contributed to the Escrow Fund on behalf of such shareholder (and on any
voting securities added to the Escrow Fund in respect of such shares of ISSI
Common Stock) so long as such shares of ISSI Common Stock or other voting
securities are held in the Escrow Fund.

                    (iii) Upon receipt by the Escrow Agent at any time on or
before the last day of the Escrow Period of a certificate signed by any officer
of ISSI (an "OFFICER'S CERTIFICATE"): (A) stating that ISSI has incurred and
paid or properly accrued Losses, or reasonably

                                      -39-


anticipates that it may have to pay or accrue Losses, and the dollar amount of
such Losses, (B) specifying in reasonable detail the individual items of Losses
included in the amount so stated, the date each such item was incurred and paid
or properly accrued, or the basis for such anticipated liability, and the nature
of the misrepresentation, breach of warranty or claim to which such item is
related, and (C) indicating the number of shares of ISSI Common Stock to be
disbursed to ISSI out of the Escrow Fund (assuming for this purpose no objection
is received under Section 10.2(f) hereof), the Escrow Agent shall, subject to
the provisions of Section 10.2(f) hereof, deliver to ISSI out of the Escrow
Fund, as promptly as practicable, such amounts held in the Escrow Fund equal to
such Losses. In the event that the number of shares to be disbursed to ISSI out
of the escrow fund changes due to a change in the Fair Market Value during the
period of time provided herein for the objection of the Agent and the subsequent
arbitration of the matter, ISSI shall provide a further instruction to the
Escrow Agent as to the number of shares to be disbursed based on the updated
Fair Market Value (determined in accordance with Section 10.2(e)(iv) below).

                    (iv) For the purposes of determining the number of shares of
ISSI Common Stock to be disbursed to ISSI out of the Escrow Fund, the shares of
ISSI Common Stock shall be valued at the Fair Market Value of such shares. For
purposes hereof, the "FAIR MARKET VALUE" of the ISSI Common Stock shall be
determined by using the average closing price of the ISSI Common Stock as
reported in the Wall Street Journal, for the ten (10) consecutive trading days
ending five (5) days prior to the date that the shares of ISSI Common Stock are
disbursed to ISSI out of the Escrow Fund; provided, however, that for purposes
of any unresolved claims as of the end of the Escrow Period pursuant to Section
10.2(c) hereof or any period thereafter, the "Fair Market Value" of the ISSI
Common Stock shall be determined by using the average closing price of the ISSI
Common Stock as reported in the Wall Street Journal for the ten (10) consecutive
trading days ending five (5) days prior to the last day of the Escrow Period.

               (f) Objections to Claims. At the time of delivery of any
Officer's Certificate to the Escrow Agent, a duplicate copy of such certificate
shall be delivered to the Agent (as defined in Section 10.2(h)), and for a
period of thirty (30) days after such delivery the Escrow Agent shall make no
delivery to ISSI of any Escrow Amount specified in such Officer's Certificate
unless the Escrow Agent shall have received written authorization from the Agent
to make such delivery. After the expiration of such thirty (30) day period, the
Escrow Agent shall make delivery of an amount from the Escrow Fund in accordance
with such Officer's Certificate and Section 10.2(e) hereof, provided that no
such payment or delivery may be made if the Agent shall object in a written
statement to the claim made in the Officer's Certificate, and such statement
shall have been delivered to the Escrow Agent prior to the expiration of such
thirty (30) day period.

               (g) Resolution of Conflicts; Arbitration.

                    (i) In case the Agent shall so object in writing to any
claim or claims made in any Officer's Certificate, the Agent and ISSI shall
attempt in good faith to agree upon the rights of the respective parties with
respect to each of such claims. If the Agent and ISSI should so agree, a
memorandum setting forth such agreement shall be prepared and signed by both
parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be
entitled to rely on

                                      -40-


any such memorandum and distribute amounts from the Escrow Fund in accordance
with the terms thereof.

                    (ii) If no such agreement can be reached after good faith
negotiation, either ISSI or the Agent may demand arbitration of the matter
unless the amount of the damage or loss is at issue in pending litigation with a
third party, in which event arbitration shall not be commenced until such amount
is ascertained or both parties agree to arbitration; and in either such event
the matter shall be settled by arbitration conducted by three (3) arbitrators.
ISSI and the Agent shall each select one (1) arbitrator, and the two (2)
arbitrators so selected shall select a third arbitrator. The arbitrators shall,
within ten (10) business days after the last day of any hearings on any motion,
issue a definitive ruling on such motion. The arbitrators shall also, within
twenty (20) business days from the last day of any hearings regarding the
imposition of sanctions or the issuance of any awards, issue a definitive ruling
on the imposition of any such sanctions or the issuance of any such award in
such arbitration. The arbitrators shall also establish procedures designed to
reduce the cost and time for discovery while allowing the parties an
opportunity, adequate in the sole judgment of the arbitrators, to discover
relevant information from the opposing parties about the subject matter of the
dispute. The arbitrators shall rule upon motions to compel or limit discovery
and shall have the authority to impose sanctions, including attorneys fees and
costs, to the same extent as a court of competent law or equity, should the
arbitrators determine that discovery was sought without substantial
justification or that discovery was refused or objected to without substantial
justification. The decision of a majority of the three (3) arbitrators as to the
validity and amount of any claim in such Officer's Certificate shall be binding
and conclusive upon the parties to this Agreement, and notwithstanding anything
in Section 10.2(f) hereof, the Escrow Agent shall be entitled to act in
accordance with such decision and make or withhold payments out of the Escrow
Fund in accordance therewith. Such decision shall be written and shall be
supported by written findings of fact and conclusions which shall set forth the
award, judgment, decree or order awarded by the arbitrators. In the event that
the Escrow Agent has not received evidence of resolution under either Section
10.2(g)(i) or this Section 10.2(g)(ii), Escrow Agent shall continue to hold the
Escrow Funds in accordance herewith.

                    (iii) Judgment upon any award rendered by the arbitrators
may be entered in any court having jurisdiction. Any such arbitration shall be
held in Santa Clara County, California under the rules then in effect of the
American Arbitration Association. The non-prevailing party (as determined by the
arbitrators) in any arbitration pursuant to this Section 10.2(g) shall pay the
reasonable fees and expenses of each party to such arbitration, as well as the
fees of each arbitrator and the administrative fee of the American Arbitration
Association; provided, however, that if the non-prevailing party is the
shareholders of Purple Ray, such expenses may only be recovered from the
proceeds from the sale of Escrow Stock from the Escrow Fund.

               (h) Agent of the Shareholders; Power of Attorney.

                    (i) In the event that the Merger is approved by the
shareholders of Purple Ray, effective upon such vote, and without further act of
any shareholder, Chris Wu is appointed as agent and attorney-in-fact (together,
the "AGENT") for each shareholder of Purple Ray on whose behalf shares were
deposited into escrow, for and on behalf of shareholders of Purple Ray,

                                      -41-


to give and receive notices and communications, to authorize delivery to ISSI of
shares from the Escrow Fund in satisfaction of claims by ISSI, to object to such
deliveries, to agree to, negotiate, enter into settlements and compromises of,
and demand arbitration and comply with orders of courts and awards of
arbitrators with respect to such claims, and to take all actions necessary or
appropriate in the judgment of Agent for the accomplishment of the foregoing.
Such agency may be changed by the shareholders of Purple Ray from time to time
upon not less than thirty (30) days' prior written notice to ISSI and Escrow
Agent signed by former Purple Ray Shareholders representing a majority in
interest of the Escrow Amount in the Escrow Fund; provided that the Agent may
not be removed unless former Purple Ray Shareholders representing a two-thirds
interest of the Escrow Amount in the Escrow Fund agree to such removal and to
the identity of the substituted agent. No bond shall be required of the Agent,
and the Agent shall not receive compensation for his or her services. Notices or
communications to or from the Agent shall constitute notice to or from each of
the shareholders of Purple Ray.

                    (ii) The Agent shall not be liable for any act done or
omitted hereunder as Agent while acting in good faith and in the exercise of
reasonable judgment. The shareholders of Purple Ray on whose behalf the Escrow
Amount was contributed to the Escrow Fund shall severally indemnify the Agent
and hold the Agent harmless against any loss, liability or expense incurred
without negligence or bad faith on the part of the Agent and arising out of or
in connection with the acceptance or administration of the Agent's duties
hereunder, including the reasonable fees and expenses of any legal counsel
retained by the Agent.

               (i) Actions of the Agent. A decision, act, consent or instruction
of the Agent shall constitute a decision of all the shareholders for whom a
portion of the Escrow Amount otherwise issuable to them are deposited in the
Escrow Fund and shall be final, binding and conclusive upon each of such
shareholders, and the Escrow Agent and ISSI may rely upon any such decision,
act, consent or instruction of the Agent as being the decision, act, consent or
instruction of each every such shareholder of Purple Ray. The Escrow Agent and
ISSI are hereby relieved from any liability to any person for any acts done by
them in accordance with such decision, act, consent or instruction of the Agent.
After all claims for Losses by ISSI set forth in Officer's Certificates
delivered to the Escrow Agent and the Agent have been satisfied, or reserved
against, the Agent, in the manner provided in the Escrow Agreement, may recover
from the Escrow Fund at the end of the Escrow Period payments not yet paid for
any expenses incurred in connection with the Agent's representation hereby.

               (j) Third-Party Claims. In the event ISSI becomes aware of a
third-party claim which ISSI believes may result in a demand against the Escrow
Fund, ISSI shall notify the Agent as soon as practicable of such claim, and the
Agent and the shareholders of Purple Ray shall be entitled, at their expense, to
participate in any defense of such claim. ISSI shall have the right in its sole
discretion to settle any such claim; provided, however, that except with the
consent of the Agent, no settlement of any such claim with third-party claimants
shall alone be determinative of the amount of any claim against the Escrow Fund.
In the event that the Agent has consented to any such settlement, the Agent
shall have no power or authority to object under any provision of this Section
10 to the amount of any claim by ISSI against the Escrow Fund with respect to
such settlement to the extent that such amount is consistent with the terms of
such settlement.

                                      -42-


               (k) Escrow Agent's Duties.

                    (i) The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth in this Agreement, the
Escrow Agreement and as set forth in any additional written escrow instructions
which the Escrow Agent may receive after the date of this Agreement which are
signed by an officer of ISSI and the Agent, and may rely and shall be protected
in relying or refraining from acting on any instrument reasonably believed to be
genuine and to have been signed or presented by the proper party or parties. The
Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow
Agent while acting in good faith and in the exercise of reasonable judgment, and
any act done or omitted pursuant to the advice of counsel shall be conclusive
evidence of such good faith.

                    (ii) The Escrow Agent is hereby expressly authorized to
disregard any and all warnings given by any of the parties hereto or by any
other person, excepting only orders or process of courts of law, and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree of any court, the Escrow Agent shall not be liable to any of the
parties hereto or to any other person by reason of such compliance,
notwithstanding any such order, judgment or decree being subsequently reversed,
modified, annulled, set aside, vacated or found to have been entered without
jurisdiction.

                    (iii) The Escrow Agent shall not be liable in any respect on
account of the identity, authority or rights of the parties executing or
delivering or purporting to execute or deliver this Agreement or any documents
or papers deposited or called for hereunder.

                    (iv) The Escrow Agent shall not be liable for the expiration
of any rights under any statute of limitations with respect to this Agreement or
any documents deposited with the Escrow Agent.

                    (v) The Escrow Agent may resign as Escrow Agent at any time
with or without cause by giving at least thirty (30) days' prior written notice
to each of ISSI and the Agent, such resignation to be effective thirty (30) days
following the date such notice is given. In addition, ISSI and Agent may jointly
remove the Escrow Agent as escrow agent at any time with or without cause, by an
instrument (which may be executed in counterparts) given to the Escrow Agent,
which instrument shall designate the effective date of such removal. In the
event of any such resignation or removal, a successor escrow agent which shall
be a bank or trust company organized under the laws of the United States of
America or any state thereof having a combined capital and surplus of not less
than $100,000,000, shall be appointed by ISSI with the approval of Agent, which
approval shall not be unreasonably withheld. Any such successor escrow agent
shall deliver to ISSI and the Agent a written instrument accepting such
appointment, and thereupon it shall succeed to all the rights and duties of the
Escrow Agent hereunder and shall be entitled to receive the Escrow Fund.
Thereafter, the predecessor Escrow Agent shall be discharged for any further
duties and liabilities under this Agreement.

                                      -43-


                    (vi) The parties hereto, and their respective shareholders,
successors and assigns hereby agree that, to the extent that the matters
addressed in the Escrow Agreement, including with respect to the liability of
the Escrow Agent and indemnification of the Escrow Agent are not otherwise
addressed herein, such Escrow Agreement shall be deemed to be incorporated by
reference herein.

(10) days after such written notice is delivered by ISSI to Purple Ray;
provided, however, that no cure period shall apply if such breach is not capable
of cure, (ii) if the Closing shall not have occurred on or before March 11, 2002
by reason of the failure of any condition precedent under Section 9.1 hereof,
other than Section 9.1(k), unless the failure results primarily from ISSI itself
breaching any representation, warranty, or covenants contained in this
Agreement, or (iii) if the Closing shall not have occurred on or before March
11, 2002 by reason of the failure of the condition precedent under Section
9.1(k);

               (c) ISSI may terminate this Agreement immediately if (i) the

recommendation of this Agreement or the Merger or have recommended, endorsed,

otherwise failed to comply with any provision of Section 7.7; and

               (d) Purple Ray may terminate this Agreement by giving written

breached any representation, warranty, or covenant contained in this Agreement
such that any of the conditions set forth in Sections 9.2(a) and 9.2(b) of the
Agreement would not be satisfied, provided that Purple Ray has notified ISSI in
writing of the basis for claiming such breach and such breach has not been cured

ISSI; provided, however, that no cure period shall apply if such breach is not
capable of cure, (ii) if the Closing shall not have occurred on or before March
11, 2002, by reason of the failure of any condition precedent under Section 9.2
hereof, other than Section 9.2(f) unless the failure results primarily from
Purple Ray breaching any representation, warranty, or covenants contained in
this Agreement, or (iii) if the Closing shall not have occurred on or before
March 11, 2002 by reason of the failure of the condition precedent under Section
9.2(f).

                                      -44-


          11.2 Effect of Termination. If any Party terminates this Agreement
pursuant to Section 11.1 above, all rights and obligations of the Parties
hereunder shall terminate without any liability of any Party to any other Party;
provided, however, that each Party hereto shall remain liable for any breach of
any representation, warranty, covenant or other provision of this Agreement that
occurs prior to the Agreement's termination; and provided further, however, that
the provisions of Sections 8.4, 11.3 and 12.1 above shall survive termination.

provided, however that if the Merger is consummated, ISSI shall bear up to
$60,000 of the expenses incurred by Purple Ray (including amounts paid by Purple
Ray prior to the Effective Time of the Merger) in connection with the Merger.
Any expenses incurred by Purple Ray in connection with the Merger in excess of
such $60,000 shall give rise to a claim by ISSI against the Escrow Fund.

               (b) In the event

                    (i) ISSI shall terminate this Agreement pursuant to Section
11.1(c)(i),

                    (ii) ISSI shall terminate this Agreement pursuant to Section

press release or make any public announcement relating to the subject matter of
this Agreement prior to the Closing without the prior written approval of ISSI
