securities or rights convertible or exchangeable into shares of Common Stock. Except
as set forth on Section 3.7(b) of the Disclosure Schedule, the issuance and
sale of the Notes will not obligate the Company to issue shares of Common Stock
or other securities to any Person (other than the Purchasers) and will not
result in a right of any holder of Company securities to adjust the exercise,
conversion, exchange or reset price under such securities. No anti-dilution
rights of any capital stock or other securities issued by the Company shall be
triggered as a result of the transactions contemplated hereby. To the Knowledge
of the Company, except as specifically disclosed in Section 3.7(b) of the
Disclosure Schedule, no Person or group of related Persons beneficially owns
(as determined pursuant to Rule 13d-3 under the Exchange Act), or has the right
to acquire, by agreement with or by obligation binding upon the Company,
beneficial ownership of in excess of 5% of the outstanding Common Stock,
ignoring for such purposes any limitation on the number of shares of Common
Stock that may be owned at any single time.

 

(c)                                  Set forth in Section 3.7(c) of the Disclosure
Schedule is a complete and accurate list of all securities of the Company that
are entitled to preemptive, registration or similar rights accompanied by

a description of such rights.
No Person has any right of first refusal, preemptive right, right of
participation, or any similar right to participate in the issuance and sale of
the Notes in the transactions contemplated by the Transaction Documents.

 

(d)                                 The Notes are duly authorized, will be issued
in compliance with the registration and qualification requirements of all
applicable federal, state, provincial, and foreign securities laws and will be
free and clear of all other Liens, other than any Liens created by the
Purchasers. All of the issued and outstanding shares of the Company’s capital
stock are duly authorized, validly issued, fully paid and non-assessable, and
were issued in compliance with the registration and qualification requirements
of all applicable federal, state, provincial, and foreign securities laws.

 

(e)                                  Section 3.7(e) of the Disclosure
Schedule sets forth a true and complete list of (x) each of the
Subsidiaries of the Company and (y) the aggregate number of authorized
shares of capital stock of such Subsidiary. The Company owns all of the issued
and outstanding capital stock of the Subsidiaries, free and clear of all Liens
other than Liens in favor of the holders of the Existing Notes. All of such
shares of capital stock are duly authorized, validly issued, fully paid and non-assessable,
and were issued in compliance with the registration and qualification
requirements of all applicable federal, state, provincial, and foreign
securities laws. There are no options, warrants, conversion privileges,
subscription or purchase rights or other rights presently outstanding to
purchase or otherwise acquire any authorized but unissued, unauthorized or
treasury shares of capital stock or other securities of, or any proprietary
interest in, any of the Subsidiaries, and there is no outstanding security of
any kind convertible into or exchangeable for such shares or proprietary
interest.

 

Section 3.8                                                No Default or Breach; Contractual
Obligations; Restrictions on Business.

 

(a)                                  Except as set forth on Section 3.8(a) of the
Disclosure Schedule, neither the Company nor any Subsidiary has received notice
of a default and is not in material default under, or with respect to, any
Contractual Obligation filed as an exhibit to or described in the SEC Documents
or which is otherwise material to the Condition of the Company, nor does any condition
exist that with notice or lapse of time or both would constitute a material
default thereunder. All of such Contractual Obligations are valid, subsisting,
in full force and effect and binding upon the Company or such Subsidiary and
the other parties thereto, and the Company or such Subsidiary has paid in full
or accrued all amounts due thereunder and has satisfied in full or provided for
all of its liabilities and obligations thereunder. To the Knowledge of the
Company, no other party to any such Contractual Obligation is in material
default thereunder, nor does any condition exist that with notice or lapse of
time or both would constitute a material default by such other party thereunder.
There is no agreement (non-competition or otherwise), commitment, judgment,
injunction, order or decree to which the Company or any of its Subsidiaries is
a party or otherwise binding upon the Company or any of its Subsidiaries which
has or may reasonably be expected to have the effect of (i) prohibiting or
impairing (A) any business practice of the Company or any of its
Subsidiaries, (B) any acquisition of property (tangible or intangible) by
the Company or any of its Subsidiaries, or (C) the conduct of business by
the Company or any of its Subsidiaries, or (ii) otherwise limiting the
freedom of the Company or any of its Subsidiaries, to engage in any line of
business or to compete with any Person. Without limiting the generality of the
foregoing, neither the Company nor any of its Subsidiaries has entered into any
Contract under which the Company or any Subsidiary is, restricted from selling,
licensing, manufacturing or otherwise distributing any of its Company
Intellectual Property or Company or Subsidiary products or from providing
services to customers or potential customers or any class of customers, in any
geographic area, during any period of time, or in any segment of the market.

(b)                                 Section 3.8(b) of the Disclosure Schedule
identifies (i) each Contractual Obligation which involves prospective fixed
and/or contingent payments or expenditures by the Company or its Subsidiaries
of more than $250,000, and (ii) each Contractual Obligation that is material to
the Condition of the Company other than those filed as an exhibit to or
described in the SEC Documents.

 

Section 3.9                                                Title to Properties.  The Company has provided Purchasers
true, correct and complete copies of all leases, lease guaranties, subleases,
agreements for the leasing, use or occupancy of, or otherwise granting a right
in or relating to property leases or otherwise occupied by the Company or any
of its Subsidiaries (the “Leased Real Property”), including all
amendments, terminations and modifications thereof (the “Lease Agreements”);
and there are no other Lease Agreements for real property to which the Company
or any of its Subsidiaries is bound, other than those identified in the Lease
Agreements. All such Lease Agreements are valid,  in full force and effect, enforceable in
accordance with their terms, and (x) with respect to the Company and its
Subsidiaries under any of such leases, no rentals are past due and there is no
existing default or event of default (or event which with notice or lapse of
time, or both, would constitute a default) and (y) to the Knowledge of the
Company, with respect to any other Person under any of such leases, no rentals
are past due and there is no existing default or event of default (or event
which with notice or lapse of time, or both, would constitute a default). Neither
the Company nor any of its Subsidiaries could be required to expend more than
$50,000 in causing any Leased Real Property to comply with the surrender
conditions set forth in the applicable Lease Agreement. Neither the Company nor
or any of its Subsidiaries have received any notice of a default, alleged
failure to perform, or any offset or counterclaim with respect to any such
Lease Agreement, which has not been fully remedied and withdrawn. There are no
other parties occupying, or with a right to occupy, the Leased Real Property
other than the Company and its Subsidiaries.

 

Section 3.10                                          SEC Documents; Proxy Statement; Financial
Statements.

 

(a)                                  Since August 1, 2004, the Company has filed
all reports, schedules, forms, statements and other documents required to be
filed by it with the SEC pursuant to the reporting requirements of the Exchange
Act (all of the foregoing filed prior to the date hereof and all exhibits
included therein and financial statements and schedules thereto and documents
incorporated by reference therein being hereinafter referred to as the “SEC
Documents”). As of their respective dates, the SEC Documents complied with
the requirements of the Exchange Act and the rules and regulations of the SEC
promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they were filed with the SEC, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading.

 

(b)                                 As of their respective dates, the Financial
Statements of the Company and its Subsidiaries included in the SEC Documents
complied as to form with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto. The Financial Statements
have been prepared in accordance with GAAP, consistently applied, during the
periods involved (except in the case of unaudited interim statements, to the
extent they may exclude footnotes or may be condensed or summary statements)
and fairly present the financial position of the Company and its Subsidiaries
as of the dates thereof and the results of its operations and cash flows for
the periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments).

 

Section 3.11                                          Taxes.  The Company and each Subsidiary has timely paid all Taxes which
have come due and are required to be paid by it, and all deficiencies or other
additions to Tax,

being disputed by the Company or any Subsidiary in good faith for which
adequate reserves have been made in accordance with GAAP. The Company and each
Subsidiary have timely paid or withheld with respect to their employees and
other third parties (and timely paid over any withheld amounts to the
appropriate Taxing authority) all federal, state and provincial income taxes,
Federal Insurance Contribution Act amounts, Federal Unemployment Tax Act
amounts and other Taxes required to be withheld. The Company and each
Subsidiary has timely filed or caused to be filed all Tax returns, reports,
forms and other such documents (“Tax Returns”) that it is required to
file (including all applicable extensions), and all such Tax Returns are
accurate and complete in all material respects. With respect to all Tax Returns
of the Company and each Subsidiary, (i) there is no unassessed Tax
deficiency proposed or, to the Knowledge of the Company, threatened against the
Company or any Subsidiary and (ii) no audit is in progress with respect to
any Tax Return, no extension of time is in force with respect to any date on which
any Tax Return was or is to be filed and no waiver or agreement is in force for
the extension of time for the assessment or payment of any Tax. No claim has
ever been made by an authority in a jurisdiction where the Company or any
Subsidiary does not file Tax Returns that the Company or any Subsidiary is or
may be subject to taxation by that jurisdiction. All provisions for Tax
liabilities of the Company and its Subsidiaries with respect to the Financial
Statements have been made in accordance with GAAP consistently applied, and all
liabilities for Taxes of the Company and its Subsidiaries attributable to
periods prior to or ending on the Closing Date have been adequately provided
for on the Financial Statements, and neither the Company nor any Subsidiary has
incurred any liability for Taxes since the date of the most recent Financial
Statements prior to the date hereof other than in the ordinary course of
business. There are no Liens for Taxes on the assets of the Company or any
Subsidiary. The Company is not a “United States real property holding
corporation” as that term is defined in Section 897(c)(2) of the Code and
the regulations promulgated thereunder. Neither the Company nor any Subsidiary
has (I) ever been a member of an affiliated group (within the meaning of Code
§1504(a)) filing a consolidated federal income Tax Return (other than a group
the common parent of which was the Company), (II) ever been a party to any Tax
sharing, indemnification or allocation agreement, nor does the Company or any
Subsidiary owe any amount under any such agreement, or (III) any liability for
the Taxes of any person, including under Treas. Reg. § 1.1502-6 (or any similar
provision of state, local or foreign law, including any arrangement for group
or consortium relief or similar arrangement), as a transferee or successor, by
contract, or otherwise. Neither the Company nor any Subsidiary has constituted
a “distributing corporation” or a “controlled corporation” in a distribution of
stock intended to qualify for tax-free treatment under Section 355 of the
Code. Neither the Company nor any Subsidiary has engaged in a reportable
transaction under Treas. Reg. § 1.6011-4(b), including any transaction that is
the same as or substantially similar to one of the types of transactions that
the Internal Revenue Service has determined to be a tax avoidance transaction
and identified by notice, regulation, or other form of published guidance as a
listed transaction, as set forth in Treas. Reg. § 1.6011-4(b)(2). None of the
indebtedness of the Company or any Subsidiary constitutes (i) “corporate
acquisition indebtedness” (as defined in Section 279(b) of the Code) with
respect to which any interest deductions may be disallowed under Section 279 of
the Code (ii) an “applicable high yield discount obligation” under Section
163(i) of the Code or (iii) a “disqualified debt instrument” under Section
163(l) of the Code.

 

Section 3.12                                          No Material Adverse Change; Ordinary Course
of Business.  Since
December 31, 2006, there has not been any material adverse change in the
Condition of the Company or any Subsidiary and no event has occurred or
circumstance exists which may result in such a material adverse change, except
to the extent any such change results from or is attributable to changes in
general economic or political conditions or changes affecting the industry
generally in which the Company or any Subsidiary operates (provided that such
changes do not affect the Company or any Subsidiary in a disproportionate
manner). Except as set forth in the SEC Documents filed prior to the date
hereof or as set forth on Section 3.12 of the Disclosure Schedule, since
December 31, 2006, neither the Company nor any 

 

12

 

Subsidiary
has (a) participated in any transaction material to the Condition of the
Company or any Subsidiary or otherwise acted outside the ordinary course of
business, (b) increased the compensation of any of its officers or the
rate of pay of any of its employees, except as part of regular compensation

general advertising was used by the Company or its representatives in
connection with the offer, sale or issuance of the Notes. Provided that the
representations of the Purchasers set forth in Article IV of this Agreement are
true, correct and complete, no registration of the Notes, pursuant to the
provisions of the Securities Act or any state securities or “blue sky” laws,
will be required by the offer, sale or issuance of the Notes. The Company
agrees that neither it, nor anyone acting on its behalf, shall offer to sell
the Notes or any other securities of the Company so as to require the
registration of the Notes pursuant to the provisions of the Securities Act or any
state securities or “blue sky” laws.

including Laws relating to worker classification, wages and hours, tax
withholding, prohibited discrimination, equal employment, fair employment

to any of its respective employees or independent contractors. Neither the
Company nor any Subsidiary is party to a conciliation agreement, consent decree
or other agreement or order with any federal, state, or local agency or
governmental authority with respect to employment practices. Neither the
Company nor any Subsidiary has taken any action which would constitute a “plant
closing” or “mass layoff” within the meaning of the WARN Act or similar Law,
issued any notification of a plant closing or mass layoff required by the WARN
Act or similar Law, and no terminations prior to the Closing would trigger any
notice or other obligations under the WARN Act or similar Law.

 

(b)                                 (i) Neither the Company nor any Subsidiary
has engaged in any unfair labor practices; (ii) there is (A) no

Controlled Entity maintains or contributes to, or has within the preceding six
years maintained or contributed to, or may have any liability with respect to
any Plan subject to Title IV of ERISA or Section 412 of the Code or
any “multiple employer plan” within the meaning of the Code or ERISA. Each Plan

administered in all material respects in accordance with its terms, and
complies in all material respects in form and in operation with the applicable
requirements of ERISA and the Code and other applicable Requirements of Law. All
contributions (including all employer contributions and employee salary
reduction contributions) which are due have been paid to each Plan.

 

(b)                                 No Claim with respect to the administration
or the investment of the assets of any Plan (other than routine claims for

compensation due to any employee or former employee or director or independent
contractor.

affecting any Plan requires or permits a retroactive increase in contributions,
premiums or other payments due under such insurance policy or agreement. The
level of insurance reserves under each Plan is reasonable and sufficient to
provide for all incurred but unreported claims.

 

(h)                                 Neither the Company nor any Subsidiary has
any liability, whether absolute or contingent, including any obligations under

date on which the committee or other administrator of such Equity Plans with
authority thereunder to make such awards has taken all necessary corporate
action to grant or complete such awards. No awards made under the Equity Plans

effect of failing to comply with the foregoing sentence.

Intellectual Property licensed to Company under the licenses set forth on
Section 3.19(a)(i) of the Disclosure Schedule, the Company Intellectual
Property constitutes all of the Intellectual Property that is used in,
necessary to or would otherwise be infringed by the operation of the business
of Company and its Subsidiaries as presently conducted and as contemplated in

3.19(a)(ii) of the Disclosure Schedule is subject to any outstanding Order, and
no action, suit, proceeding, hearing, investigation, charge, complaint, claim
or demand is pending or, to the Knowledge of the Company, threatened, which

all obligations imposed upon it under all IP Licenses, and is not, nor to the
Knowledge of the Company is any other party thereto, in breach of or default

to be so on identical terms immediately following the Closing except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, fraudulent conveyance or transfer, moratorium or similar laws
affecting the enforcement of creditors’ rights generally and by general principles
of equity relating to enforceability (regardless of whether considered in a
proceeding at law or in equity).

 

(b)                                 The operation of the business of Company and
its Subsidiaries, including in connection with the exploitation of the Company
Intellectual Property and the design, development, use, import, branding,
advertising, promotion, marketing, manufacture and sale of any products or
services, has not, does not, and when conducted following the Closing in the
manner presently contemplated in the respective business plans of the Company
and its Subsidiaries, will not, infringe upon, misappropriate or otherwise
violate any Intellectual Property Rights of others.

 

(c)                                  Except as set forth on Section 3.19(c) of the
Disclosure Schedule, no litigation is pending and no Claim has been made
against the Company or any Subsidiary or, to the Knowledge of the Company, is
threatened, alleging infringement, misappropriation or other violation by the
Company or any Subsidiary of any Intellectual Property Rights of others (nor
does the Company or any Subsidiary have Knowledge of any reasonable basis
therefor).

 

(d)                                 To the Knowledge of the Company, no Person is

ARTICLE VI

PREEMPTIVE RIGHTS

 

Section 6.1                                      Subsequent Offerings. Each Purchaser shall have a right of first
refusal to purchase its pro rata share
of fifty percent (50%) of all New Securities (as defined below) that the
Company may, from time to time, propose to sell and issue after the date of
this Agreement. Each Purchaser’s pro rata
share is based on such Purchaser’s pro rata portion of the aggregate
principal amount of the Notes purchased hereunder. Each Purchaser shall be
entitled to apportion the right to purchase New Securities among itself and its
general partners, limited partners, members and Affiliates in such proportions
as it deems appropriate.

 

Section 6.2                                      Exercise of Rights. If the Company proposes to issue any New
Securities, it shall give each Purchaser written notice of its intention,
describing the New Securities, the price and the terms and conditions upon which
the Company proposes to issue the same. Each Purchaser shall have twenty (20)
days from the giving of such notice to agree to purchase its pro rata share of
fifty percent (50%) of the New Securities for the price and upon the terms and
conditions specified in the notice by giving written notice to the Company and
stating therein the quantity of New Securities to be purchased. Notwithstanding
the foregoing, the Company shall not be required to offer or sell such New
Securities to any Purchaser who would cause the Company to be in violation of
applicable federal securities laws by virtue of such offer or sale.

 

Section 6.3                                      Issuance of New Securities to Other Persons. If not all of the Purchasers elect to
purchase their pro rata share of
fifty percent (50%) of the New Securities, then the Company shall promptly
notify in writing the Purchasers who do so elect and shall offer such
Purchasers the right to acquire such unsubscribed shares. Each such Purchaser
shall have ten (10) days after receipt of such notice to notify the
Company of its election to purchase all or a portion thereof of the
unsubscribed shares. If the Purchasers fail to exercise in full the rights of
first refusal, the Company shall have ninety (90) days thereafter to sell the
New Securities in respect of which the Purchaser’s rights were not exercised,
at a price and upon general terms and conditions not more favorable to the
purchasers thereof than specified in the Company’s notice to the Purchasers
pursuant to Section 6.2 hereof. If the Company has not sold such New
Securities within ninety (90) days of the notice provided pursuant to Section 6.2,
the Company shall not thereafter issue or sell any New Securities, without
first offering such securities to the Purchasers in the manner provided above.

 

Section 6.4                                      Termination. The preemptive rights provided in this Article VI shall remain
in existence until all Obligations hereunder are repaid in full; provided,
however, that if the Company does not consummate a bona fide financing
transaction involving the issuance and sale of Common Stock or Common Stock
Equivalents to the Purchasers prior to the repayment in full of the Obligations
hereunder on substantially the terms and conditions set forth in a term sheet
dated on or around the date of this Agreement, the preemptive rights provided
in this Article VI shall remain in existence until the earlier to occur of
November 30, 2009 or the second anniversary of the Tranche 2 Closing Date.

 

Section 6.5                                      Definition of New Securities. For the purposes of this Article VI, “New
Securities” shall mean, whether or not authorized on the date hereof, any
Common Stock, Common Stock Equivalent or any other security of the Company or
any of its subsidiaries; provided, however, that “New Securities” do not
include the following:

 

28

 

(a)                                  any securities that are issued or granted, to
officers, directors and employees of, or consultants or advisors to, the
Company pursuant to a stock grant, employee restricted stock purchase
agreement, option plan or purchase plan or other stock incentive program or
otherwise as part of their compensation arrangement, where such issuance
and grants are approved by the Board of Directors, or any securities issued in
respect of the exercise of any such securities;

 

(b)                                 any securities issued in connection with any
stock split, stock dividend, reclassification, reorganization or similar event
by the Company;

 

(c)                                  any securities issued or to be issued
pursuant to an acquisition or merger of another company that is approved by the
Board of Directors (not primarily for the purpose of obtaining cash);

 

(d)                                 any securities issued upon the conversion of
convertible securities or upon the exercise or rights, options or warrants, in
each case outstanding as of the Closing Date (as defined in the Purchase
Agreement), provided that such exercise or conversion occurs in accordance with
the terms thereof without amendment or modification;

 

(e)                                  any securities issued in connection with the
payment of principal and/or interest pursuant to the Existing Notes;

 

(f)                                    securities issued in connection with a bona
fide joint venture, strategic partnership or strategic alliance approved by the
Board of Directors, the primary purpose of which is not to raise capital; and

 

(g)                                 any Common Stock or Common Stock Equivalents
issued pursuant to a bona fide firm commitment underwritten public offering
with a nationally recognized underwriter in an aggregate offering amount
greater than $20,000,000.

 

ARTICLE VII

LEGENDS

 

Section 7.1                                                Legends. Each certificate representing any of the Notes shall bear legends
substantially in the following form:

 

“THIS NOTE HAS BEEN ACQUIRED
BY THE HOLDER FOR ITS OWN ACCOUNT, FOR INVESTMENT PURPOSES AND NOT WITH A VIEW
TO THE DISTRIBUTION THEREOF. THIS NOTE HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) AND ANY APPLICABLE

PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN
COMPLIANCE WITH SUCH STATE SECURITIES LAWS, IN COMPLIANCE WITH RULE 144
UNDER THE SECURITIES ACT, OR AN OPINION OF COUNSEL OR OTHER EVIDENCE REASONABLY
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION AND/OR COMPLIANCE IS NOT
REQUIRED.”

 

The Company may instruct its transfer agent not
to register the transfer of the Notes, unless the conditions specified in the
foregoing legend are satisfied.

 

Section 7.2                                                Removal of Legends. Any legend endorsed on a certificate
pursuant to Section 6.1 and the stop transfer instructions with
respect to such Notes as it applies to Section 6.1 

 

29

 

shall
be removed and the Company shall issue a certificate without such legend to the
holder of such Notes (i) if such legend may be properly removed under
the terms of Rule 144 promulgated under the Securities Act or another
exemption under the Securities Act or (ii) if such holder provides the
Company with an opinion of counsel for such holder, reasonably satisfactory to
legal counsel for the Company, to the effect that a sale, transfer or
assignment of such Notes may be made without Registration.

 

ARTICLE VIII

INDEMNIFICATION

 

Section 8.1                                                Indemnity. The Company agrees to indemnify and defend and hold harmless the Purchasers,
their Affiliates, successors and assigns and each of their respective officers,
directors, members, partners, employees and agents (each, a “Indemnified
Party,” and collectively, the “Indemnified Parties”) from and
against, and agrees to pay or cause to be paid to the Indemnified Parties all
amounts equal to the sum of, any and all claims, demands, costs, expenses,
losses and other liabilities of any kind (“Losses”) that the Indemnified
Parties may incur or suffer (including without limitation all reasonable
legal fees and expenses) which arise or result from any breach of any of its
representations or warranties, or failure by the Company to perform any of
its covenants or agreements, in, or any transactions contemplated by, this
Agreement or any other Transaction Document or any certificate or document
delivered pursuant to this Agreement or any other Transaction Document,
including but not limited to any third party claims arising or resulting in
connection therewith, except to the extent such Losses arise out of the gross
negligence or willful misconduct of such Indemnified Party. The rights of the
Purchasers hereunder shall be in addition to, and not in lieu of, any other
rights and remedies which may be available to them by law or under this
Agreement or the Transaction Documents.

 

Section 8.2                                                Procedures. If a third party shall notify an Indemnified Party with respect to
any matter that may give rise to a claim for indemnification under the
indemnity set forth above in Section 7.1, the procedures set forth
below shall be followed.

 

(a)                                  Notice. The respective Indemnified Party shall give to the Company (the “Indemnifying
Party”) written notice of any Claim for which indemnity may be sought
under Section 7.1 promptly but in any event within 30 days after
the Indemnified Party receives notice thereof, provided,
however, that failure by the
Indemnified Party to give such notice shall not relieve the Indemnifying Party
from any liability it shall otherwise have pursuant to this Agreement except to
the extent that the Indemnifying Party is actually prejudiced by such failure. Such
notice shall set forth in reasonable detail (x) the basis for such
potential claim and (y) the dollar amount, or an estimated dollar amount,
as applicable, of such claim. The Indemnifying Party shall have a period of 30
days within which to respond thereto. If the Indemnifying Party does not
respond within such 30-day period, the Indemnifying Party shall be deemed to
have accepted responsibility for such indemnity.

 

(b)                                 Defense of Claim. With respect to a claim by a third party
against an Indemnified Party for which indemnification may be sought under
this Agreement, the Indemnifying Party shall have the right, at its option and
subject to the remainder of this Section 7.2, to be represented by
counsel of its choice and to assume the defense or otherwise control the
handling of any Claim, which is set forth in the notice sent by the Indemnified
Party, by notifying the Indemnified Party in writing to such effect within 30
days of receipt of such notice; provided,
however, that the Indemnified
Party shall have the right to employ counsel to represent it if, in the
Indemnified Party’s reasonable judgment based upon the advice of counsel, it is
advisable in light of the separate interests of the Indemnified Party, to be
represented by separate counsel (including, as applicable, local counsel), and
in that event the reasonable fees and expenses of one such 

 

30

 

separate
counsel shall be paid by the Indemnifying Party plus appropriate local counsel,
if applicable, for all Indemnified Parties; and, provided  further,
that the Indemnifying Party shall not have the right to assume the defense of
such Claim unless (i) the Indemnifying Party acknowledges fully the rights
of the Indemnified Party (and does not contest, as a whole or in part) the
Indemnified Party’s indemnification rights for the Claim, (ii) the counsel
selected by the Indemnifying Party is reasonably satisfactory to the
Indemnified Party, (iii) the Indemnified Party is kept informed of all
material developments and is furnished copies of all material papers filed or
sent to or from the opposing party or parties and (iv) the Indemnifying
Party prosecutes the defense of such Claim with commercially reasonable
diligence in a manner which does not materially prejudice the defense of such
Claim. If the Indemnifying Party does not give timely notice in accordance with
the preceding sentence, the Indemnifying Party shall be deemed to have given
notice that it does not wish to control the handling of such Claim. In the
event the Indemnifying Party elects (by notice in writing within such 30-day
period) to assume the defense of or otherwise control the handling of any such
Claim for which indemnity is sought, the Indemnifying Party shall indemnify and
hold harmless the Indemnified Party from and against any and all reasonable
professional fees (including attorneys’ fees, accountants, consultants and
engineering fees) and investigation expenses incurred by the Indemnified Party
after it provides notice under clause (a) and prior to such election,
notwithstanding the fact that the Indemnifying Party may not have been so
liable to the Indemnified Party had the Indemnifying Party not elected to
assume the defense of or to otherwise control the handling of such Claim. In
the event that the Indemnifying Party does not assume the defense or otherwise
control the handling of such matter, the Indemnified Party may retain
counsel, as an indemnification expense, to defend such Claim.

 

(c)                                  Final Authority. The Parties shall cooperate in the defense
of any such Claim and each shall make available all books and records which are
relevant in connection with such claim or litigation. In connection with any
Claim with respect to which the Indemnifying Party has assumed the defense or
control, the Indemnifying Party will not consent to the entry of any judgment
or enter into any settlement with respect to any matter which does not include
a provision whereby the plaintiff or claimant in the matter releases the
Indemnified Party from all liability with respect thereto, without the written
consent of the Indemnified Party, which shall not be unreasonably withheld. In
connection with any Claim with respect to which the Indemnifying Party has not
assumed the defense or control, the Indemnified Party may not compromise
or settle such Claim without the consent of the Indemnifying Party, which shall
not be unreasonably withheld or delayed.

 

(d)                                 Claims Between the Indemnifying Party and the
Indemnified Party. Any Claim
for indemnification under this Agreement which does not result from the
assertion of a Claim by a third party shall be asserted by written notice given
by the Indemnified Party to the Indemnifying Party. The Indemnifying Party
shall have a period of 30 days within which to respond thereto.

Company or any of its Subsidiaries (other than any Transaction Document), whether

expressly waived, anything contained in this Note or in the other Transaction
Documents to the contrary notwithstanding. In addition to the foregoing
remedies, upon the occurrence or existence of any Event of Default, the Holder may exercise

hereby agree as follows:

 

1.                                      Definitions and
Interpretation.

 

(a)                                  Definition. When used in this Guaranty, the following terms shall have the
following respective meanings:

 

“Adjusted Maximum
Guaranty Amount” shall mean, with respect to any Guarantor, the
maximum liability of such Guarantor under this Guaranty, limited to the extent
provided in Section 2(d) hereof (except that, for purposes of
calculating the Adjusted Maximum Guaranty Amount of a Guarantor only, any
assets or liabilities of such Guarantor arising under Section 6
hereof shall be ignored).

 

“Aggregate
Guaranty Payments” shall mean, with respect to any Guarantor at any
time, the aggregate net amount of all  payments

computed at the rate provided in the Notes and claims for reimbursement, costs,
expenses or indemnities under the terms of any of the Transaction Documents
accruing or claimed at any time after the commencement of any Insolvency 

 

 

Proceeding,
if the claim for such interest, reimbursement, costs, expenses or indemnities
is not allowable, allowed or enforceable against the Company in such Insolvency
Proceeding.

 

“Fair Share”
shall mean, with respect to any Guarantor at any time, an amount equal to (i) a
fraction, the numerator of which is the Adjusted Maximum Guaranty Amount of
such Guarantor and the denominator of which is the aggregate Adjusted Maximum
Guaranty Amounts of all  Guarantors,
multiplied by (ii) the aggregate amount paid by all Funding Guarantors
under this Guaranty at or prior to such time.

 

“Fair Share
Shortfall” shall mean, with respect to any Guarantor at any time,
the amount, if any, by which the Fair Share of such Guarantor at such time
exceeds the Aggregate Guaranty Payments of such Guarantor at such time.

 

“Funding Guarantor”
shall have the meaning given to that term in Section 6 hereof.

 

“Guaranteed
Obligations” shall mean the Obligations.

 

“Guarantor”
shall have the meaning given to that term in the introductory paragraph hereof.

States Bankruptcy Code or any other similar law, rule or regulation of the
United States or any jurisdiction or any other action or proceeding for the
reorganization, liquidation, appointment of a receiver, rearrangement of debts,
marshalling of assets or similar action relating to any Guarantor, their respective
creditors or any substantial part of their respective assets, whether or
not any such case, proceeding or action is voluntary or involuntary.

 

“Investor”
shall have the meaning given to that term in the introductory paragraph hereof.

 

“Purchase Agreement”
shall have the meaning given to that term in Recital A hereof

 

“Subordinated
Obligations” shall have the meaning given to that term in Section 4
hereof.

 

Unless otherwise defined herein, all other
capitalized terms used herein and defined in the Purchase Agreement shall have
the respective meanings given to those terms in the Purchase Agreement.

 

(b)                                 Other Interpretive Provisions. The rules of construction set forth in
the Purchase Agreement shall, to the extent not inconsistent with the terms of
this Guaranty, apply to this Guaranty and are hereby incorporated by reference.
Each Guarantor acknowledges receipt of copies of the Purchase Agreement and the
other Transaction Documents.

 

2.                                      Guaranty.

 

(a)                                  Payment Guaranty. Each Guarantor unconditionally guarantees
and promises to pay and perform as and when due, whether at stated
maturity, upon acceleration or otherwise, any and all of the Guaranteed
Obligations. If any Insolvency Proceeding relating to the Company is commenced,
each Guarantor further unconditionally guarantees and promises to pay and
perform, upon the demand of Purchasers, any and all of the Guaranteed
Obligations (including any and all Disallowed Post-Commencement Interest and

Proceeding. This Guaranty is a guaranty of payment and not of collection.

 

D-2

 

(b)                                 Continuing Guaranty. This Guaranty is an irrevocable continuing
guaranty of the Guaranteed Obligations which shall continue in effect until all
of the Guaranteed Obligations have been fully, finally and indefeasibly paid. If
any payment on any Guaranteed Obligation is set aside, avoided or rescinded or
otherwise recovered from the Purchasers, such recovered payment shall
constitute a Guaranteed Obligation hereunder and, if this Guaranty was
previously released or terminated, it automatically shall be fully reinstated,
as if such payment was never made.

 

(c)                                  Independent Obligation. The liability of each Guarantor hereunder
is independent of the Guaranteed Obligations and of the obligations of each
other Guarantor hereunder, and a separate action or actions may be brought
and prosecuted against each Guarantor irrespective of whether action is brought
against the Company, any other Guarantor or any other guarantor of the
Guaranteed Obligations or whether the Company, any other Guarantor or any other
guarantor of the Guaranteed Obligations is joined in any such action or
actions.

 

(d)                                 Fraudulent Transfer Limitation. If, in any action to enforce this Guaranty,
any court of competent jurisdiction determines that enforcement against any
Guarantor for the full amount of the Guaranteed Obligations is not lawful under
or would be subject to avoidance under Section 548 of the United States
Bankruptcy Code or any applicable provision of any comparable law of any state
or other jurisdiction, the liability of such Guarantor under this Guaranty
shall be limited to the maximum amount lawful and not subject to such
avoidance.

 

(e)                                  Termination. Notwithstanding any termination of this Guaranty, this Guaranty shall
continue to be in full force and effect and applicable to any Guaranteed
Obligations arising thereafter which arise because prior payments of Guaranteed
Obligations are rescinded or otherwise required to be surrendered by the
Purchasers after receipt.

 

3.                                      Authorizations, Waivers, Etc.

 

(a)                                  Authorizations. Each Guarantor authorizes the Purchasers,
in their discretion, without notice to such Guarantor, irrespective of any
change in the financial condition of the Company, such Guarantor, any other
Guarantor or any other guarantor of the Guaranteed Obligations since the date
hereof, and without affecting or impairing in any way the liability of such
Guarantor hereunder, from time to time to:

of sale thereof; and purchase such security at public or private sale;

 

(iii)                               Otherwise exercise any right or remedy they may have against the

Guaranteed Obligations or any security, including, without limitation, the
right to foreclose upon any such security by judicial or nonjudicial sale;

(b)                                 Waivers. Each Guarantor hereby waives:

 

(i)                                     Any right to require the Purchasers to (A) proceed
against the Company, any other Guarantor or any other guarantor of the
Guaranteed Obligations, (B) proceed against or exhaust any security
received from the Company, such Guarantor, any other Guarantor or any other
guarantor of the Guaranteed Obligations or otherwise marshal the assets of the
Company, such Guarantor, any other Guarantor or any other guarantor of the

of reimbursement, subrogation, contribution or other right or remedy of
Guarantor against the Company, any other Guarantor, any other guarantor of the
Guaranteed Obligations or any security, whether resulting from an election by
the Purchasers to foreclose upon security by nonjudicial sale, or otherwise;

 

(iv)                              Any setoff or counterclaim of the Company or any defense which results

enforcement from any cause whatsoever of the liability of the Company
(including, without limitation, the lack of validity or enforceability of any
of the Transaction Documents);

indefeasibly paid, any right to revoke this Guaranty;

 

(xii)                             Any defense arising from an election for the application of Section 1111(b)(2) of
the United States Bankruptcy Code which applies to the Guaranteed Obligations;

(c)                                  Financial Condition of the Company, Etc. Each Guarantor is fully aware of the
financial condition and affairs of the Company. Each Guarantor has executed this
Guaranty without reliance upon any representation, warranty, statement or
information concerning the Company furnished to such Guarantor by the
Purchasers and has, independently and without reliance on the Purchasers and
based on such documents and information as it has deemed appropriate, made its
own appraisal of the financial condition and affairs of the Company and of
other circumstances affecting the risk of nonpayment or nonperformance of the
Guaranteed Obligations. Each Guarantor is in a position to obtain, and assumes
full responsibility for obtaining, any additional information about the
financial condition and affairs of the Company and of other circumstances
affecting the risk of nonpayment or nonperformance of the Guaranteed
Obligations and will, independently and without reliance upon the Purchasers,
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own appraisals and decisions in taking or not taking
action in connection with this Guaranty.

 

4.                                      Subordination. Each Guarantor hereby subordinates any and
all debts, liabilities and obligations owed to such Guarantor by the Company or
any Subsidiary of the Company (the “Subordinated
Obligations”) to the Guaranteed Obligations as provided in this Section 4.

 

(a)                                  Prohibited Payments, Etc. Until the occurrence of a Default or an
Event of Default or any default by any Guarantor hereunder, each Guarantor and
its Subsidiaries may receive regularly scheduled payments from the Company
on account of Subordinated Obligations. After the occurrence and during the
continuance of any Default or Event of Default or any default by any Guarantor
hereunder (including the commencement and continuation of any Insolvency
Proceeding relating to the Company, however, unless the Purchasers otherwise
request, no Guarantor shall, nor shall it permit any of its Subsidiaries to,
demand, accept or take any action to collect any payment on account of the
Subordinated Obligations.

 

(b)                                 Prior Payment of Guaranteed Obligation. In any Insolvency Proceeding relating to
the Company, each Guarantor agrees that the Purchasers shall be entitled to
receive payment of all Guaranteed Obligations (including any and all Disallowed
Post-Commencement Interest and Expenses) before such Guarantor or any of its
Subsidiaries receives payment of any Subordinated Obligations.

 

(c)                                  Turn-Over. After the occurrence and during the continuance of any Default or
Event of Default (including the commencement and continuation of any Insolvency
Proceeding relating to the Company), each Guarantor and its Subsidiaries shall,
if the Purchasers so request, collect, enforce and receive payments on account
of the Subordinated Obligations as trustee for the Purchasers and deliver such
payments to the Purchasers on account of the Guaranteed Obligations (including
any and all Disallowed Post-Commencement Interest and Expenses), together with
any necessary endorsements or other instruments of 

 

D-5

 

transfer,
but without reducing or affecting in any manner the liability of such Guarantor
under the other provisions of this Guaranty.

 

(d)                                 Investor Authorization. After the occurrence and during the
continuance of any Default or Event of Default or any default by a Guarantor hereunder
(including the commencement and continuation of any Insolvency Proceeding
relating to the Company, the Purchasers are authorized and empowered (but
without any obligation to so do), in their discretion, (i) in the name of
each Guarantor and its Subsidiaries, to collect and enforce, and to submit
claims in respect of, Subordinated Obligations and to apply any amounts
received thereon to the Guaranteed Obligations (including any and all
Disallowed Post-Commencement Interest and Expenses), and (ii) to require
each Guarantor (A) to collect and enforce, and to submit claims in respect
of, Subordinated Obligations and (B) to pay any amounts received on such
obligations to the Purchasers for application to the Guaranteed Obligations
(including any and all Disallowed Post-Commencement Interest and Expenses).

 

5.                                      General Pledge; Setoff.

 

(a)                                  Pledge. In addition to all liens upon and rights of setoff against the
property of any Guarantor given to the Purchasers by law or separate agreement
to secure the liabilities of any Guarantor hereunder, to the extent permitted
by law, each Guarantor hereby grants to the Purchasers, as security for such
Guarantor’s obligations hereunder, a security interest in all monies,
securities and other property of such Guarantor now or hereafter in the
possession of the Purchasers; and the Purchasers shall have all rights and
remedies of a secured party with respect to such property.

 

(b)                                 Setoff. In addition to any rights and remedies of the Purchasers provided by
law, each Investor shall have the right, without prior notice to any Guarantor,
any such notice being expressly waived by each Guarantor to the extent
permitted by applicable law, upon the occurrence and during the continuance of
a Default or an Event of Default, to set-off and apply against the Guaranteed
Obligations any amount owing from such Investor to such Guarantor.

 

(c)                                  Nonwaiver. No security interest or right of setoff shall be deemed to have been
waived by any act or conduct on the part of the Purchasers or by any failure
to exercise such right of setoff or to enforce such security interest, or by
any delay in so doing; and every right of setoff and security interest shall
continue in full force and effect until such right of setoff or security
interest is specifically waived or released by an instrument in writing
executed by the Purchasers.

 

6.                                      Contribution among
Guarantors. The
Guarantors desire to allocate among themselves, in a fair and equitable manner,
their rights of contribution from each other when any payment is made by any
Guarantor under this Guaranty. Accordingly, if any payment is made by any
Guarantor under this Guaranty (a “Funding
Guarantor”) that exceeds its Fair Share, the Funding Guarantor shall
be entitled to a contribution from each other Guarantor in the amount of such
other Guarantor’s Fair Share Shortfall, so that all such contributions shall
cause each Guarantor’s Aggregate Guaranty Payments to equal its Fair Share. The
amounts payable as contributions hereunder shall be determined by the Funding
Guarantor as of the date on which the related payment or distribution is made
by the Funding Guarantor, and such determination shall be binding on the other
Guarantors absent manifest error. The allocation and right of contribution
among the Guarantors set forth in this Section 6 shall not be
construed to limit in any way the liability of any Guarantor under this
Guaranty or the amount of the Guaranteed Obligations.

rent, or otherwise dispose of or transfer any Collateral or right or interest
therein, and to keep the Collateral free of all Liens except, in each case, as
permitted under the Purchase Agreement; (k) if requested by Collateral
Agent, to type, print or stamp conspicuously on the face of all original copies
of all Collateral consisting of chattel paper a legend satisfactory to
Collateral Agent indicating that such chattel paper is subject to the security
interest granted hereby; (l) to collect, enforce and receive delivery of
the accounts receivable and payment intangibles in accordance with past
practice until otherwise notified by Collateral Agent; (m) to comply with
all material requirements of law relating to the production, possession,

right, at any time during normal business hours, upon reasonable prior notice,

and operating records, and make abstracts therefrom, and to discuss such Debtor’s
affairs, finances and accounts with its directors, officers and independent
public accountants; and (m) to promptly notify Collateral Agent in writing if

Security Agreement, with such writing to be in form and substance
reasonably satisfactory to Collateral Agent.

 

6.                                       Covenants Regarding Intellectual Property. Each Debtor hereby agrees:

 

E-3

 

(a)                                  Debtor will perform all acts and execute
all documents, including notices of security interest for each relevant type of
intellectual property in forms suitable for filing with the Patent and
Trademark Office or the Copyright Office, that may be necessary or
desirable to record, maintain, preserve, protect and perfect Collateral Agent’s
interest in the Collateral, the Lien granted to Collateral Agent in the
Collateral and the first priority of such Lien;

 

(b)                                 Except to the extent that Collateral Agent
gives its prior written consent:

 

(i)                                     Each Debtor (either itself or through
licensees) will continue to use its material trademarks in connection with each
and every trademark class of goods or services applicable to its current
line of products or services as reflected in its current catalogs, brochures,
price lists or similar materials in order to maintain such trademarks in full
force and effect free from any claim of abandonment for nonuse, and the Debtors
will not (and will not permit any licensee thereof to) do any act or knowingly
omit to do any act whereby any material trademark may become invalidated;

 

(ii)                                  No Debtor will do any act or omit to do any
act whereby any material patent registrations may become abandoned or
dedicated to the public domain or the remedies available against potential
infringers weakened and shall notify Collateral Agent immediately if it knows
of any reason or has reason to know that any material patent registration may become
abandoned or dedicated; and

 

(iii)                               No Debtor will do any act or omit to do any act whereby any material
copyrights or mask works may become abandoned or dedicated to the public
domain or the remedies available against potential infringers weakened and
shall notify Collateral Agent immediately if it knows of any reason or has
reason to know that any material copyright or mask work may become
abandoned or dedicated to the public domain.

 

(c)                                  Each Debtor will promptly (and in any event
within 5 days) notify Collateral Agent upon the filing, either by such Debtor
or through any agent, employee, licensee or designee, of (i) an
application for the registration of any patent or trademark, with the Patent
and Trademark Office or any similar office or agency in any other country or
any political subdivision thereof, (ii) any assignment of any patent or
trademark, which such Debtor may acquire from a third party, with the
Patent and Trademark Office or any similar office or agency in any other
country or any political subdivision thereof, or (iii) any assignment of
any copyright or mask work, which such Debtor may acquire from a third
party, with the Copyright Office or any similar office or agency in any other
country or any political subdivision thereof. Upon the request of Collateral
Agent, each Debtor shall execute and deliver any and all agreements,
instruments, documents and papers as Collateral Agent may request to
evidence Collateral Agent’s security interest in such patent, trademark (and
the goodwill and general intangibles of such Debtor relating thereto or
represented thereby), copyright or mask work, and each Debtor authorizes
Collateral Agent to amend an original counterpart of the applicable notice
of security interest executed pursuant to Section 6(a) of this
Security Agreement without first obtaining such Debtor’s approval of or
signature to such amendment and to record such document with the Patent and
Trademark Office or Copyright Office, as applicable;

 

(d)                                 While any Obligations remain outstanding, no
Debtor shall register or cause to be registered with the United States
Copyright Office any copyright registrations with respect to any proprietary
software of such Debtor or any other property that is subject to registration
with the United States Copyright Office; provided, that a Debtor may register
or cause to be registered such proprietary software or other property of such
Debtor with the United States Copyright Office if (i) such copyright
registration is made in connection with the enforcement against third parties
of such Debtor’s rights with respect to such proprietary 

 

E-4

 

software
or other property and (ii) such Debtor provides Collateral Agent five (5) business
days prior notice of such copyright registration. While any Obligations remain
outstanding, each Debtor shall file or cause to be filed with the United States
Copyright Office a copyright application with respect to any major revisions or
upgrades to any proprietary software that has previously been registered by
such Debtor with the United States Copyright Office. Each Debtor shall file for
such registration within thirty (30) days from such major revision or upgrade
and shall notify Collateral Agent in writing five (5) business days prior
to such filing.

 

(e)                                  Each Debtor will take all necessary steps in
any proceeding before the Patent and Trademark Office, the Copyright Office or
any similar office or agency in any other country or any political subdivision
thereof, to diligently prosecute or maintain, as applicable, each application and
registration of the patents, trademarks, copyrights and mask works, including
filing of renewals, affidavits of use, affidavits of incontestability and
opposition, interference and cancellation proceedings (except to the extent
that dedication, abandonment or invalidation is permitted hereunder);

 

(f)                                    Each Debtor shall (i) use proper
statutory notice in connection with its use of the patents, trademarks,
copyrights and mask works, (ii) maintain consistent standards of quality
in its manufacture of products sold under the trademarks or provision of
services in connection with the trademarks, and (iii) take all steps
necessary to protect the secrecy and the validity under applicable law of all
material trade secrets;

 

(g)                                 Each Debtor agrees that if it learns of any
use by any Person of any term or design likely to cause confusion with any
trademark, such Debtor shall promptly notify Collateral Agent of such use and
of all steps taken and to be taken to remedy any infringement of any trademark;
and

 

(h)                                 Each Debtor shall maintain with each employee
who may have access to the trade secrets of such Debtor an agreement by
which such employee agrees not to disclose such trade secrets and with each
employee who may be the inventor of patentable inventions (invented within
the scope of such employee’s employment) an invention assignment agreement
requiring such employee to assign all rights to such inventions, including
patents and patent applications, to such Debtor and further requiring such
employee to cooperate fully with such Debtor, its successors in interest,
including Collateral Agent, and their counsel, in the prosecution of any patent
application or in any litigation involving the invention, whether such
cooperation is required during such employee’s employment with such Debtor or
after the termination of such employment.

 

7.                                       Authorized Action by Collateral Agent. Each Debtor hereby irrevocably appoints
Collateral Agent as its attorney-in-fact (which appointment is coupled with an
interest) and agrees that Collateral Agent may perform (but
Collateral Agent shall not be obligated to and shall incur no liability to any
Debtor or any third party for failure so to do) any act which such Debtor is
obligated by this Security Agreement to perform, and to exercise such rights
and powers as such Debtor might exercise with respect to the Collateral,
including the right to (a) collect by legal proceedings or otherwise and
endorse, receive and receipt for all dividends, interest, payments, proceeds
and other sums and property now or hereafter payable on or on account of the
Collateral; (b) enter into any extension, reorganization, deposit, merger,
consolidation or other agreement pertaining to, or deposit, surrender, accept,
hold or apply other property in exchange for the Collateral; (c) make any
compromise or settlement, and take any action it deems advisable, with respect
to the Collateral; (d) insure, process and preserve the Collateral; (e) pay
any indebtedness of such Debtor relating to the Collateral; and (f) file
UCC financing statements and execute other documents, instruments and
agreements required hereunder; provided, however, that Collateral Agent shall
not exercise any such powers granted pursuant to subsections (a) through (e) prior
to the occurrence of an Event of Default and shall only exercise 

 

E-5

 

such
powers during the continuance of an Event of Default. Each Debtor agrees to
reimburse Collateral Agent upon demand for any reasonable costs and expenses,
including attorneys’ fees, Collateral Agent may incur while acting as such
Debtor’s attorney-in-fact hereunder, all of which costs and expenses are
included in the Obligations. It is further agreed and understood between the
parties hereto that such care as Collateral Agent gives to the safekeeping of
its own property of like kind shall constitute reasonable care of the
Collateral when in Collateral Agent’s possession; provided, however, that
Collateral Agent shall not be required to make any presentment, demand or
protest, or give any notice and need not take any action to preserve any rights
against any prior party or any other person in connection with the Obligations
or with respect to the Collateral.

 

8.                                       Litigation and Other Proceedings.

 

(a)                                   Each Debtor shall have the right and
obligation to commence and diligently prosecute such suits, proceedings or
other actions for infringement or other damage, or reexamination or reissue
proceedings, or opposition or cancellation proceedings as are reasonable to
protect any of the patents, trademarks, copyrights, mask works or trade secrets.
No such suit, proceeding or other actions shall be settled or voluntarily
dismissed, nor shall any party be released or excused of any claims of or
liability for infringement, without the prior written consent of Collateral
Agent, which consent shall not be unreasonably withheld.

 

(b)                                  Upon the occurrence and during the
continuation of an Event of Default, Collateral Agent shall have the right but
not the obligation to bring suit or institute proceedings in the name of each
Debtor or Collateral Agent to enforce any rights in the Collateral, including
any license thereunder, in which event such Debtor shall at the request of
Collateral Agent do any and all lawful acts and execute any and all documents
reasonably required by Collateral Agent in aid of such enforcement. If
Collateral Agent elects not to bring suit to enforce any right under the
Collateral, including any license thereunder, each Debtor agrees to use all
reasonable measures, whether by suit, proceeding or other action, to cause to
cease any infringement of any right under the Collateral by any Person and for
that purpose agrees to diligently maintain any action, suit or proceeding
against any Person so infringing necessary to prevent such infringement.

 

9.                                       Default and Remedies.

 

(a)                                  Default. The Debtors shall be deemed in default under this Security Agreement
upon the occurrence and during the continuance of an Event of Default (as
defined in the Notes).

 

(b)                                 Remedies. Upon the occurrence and during the continuance of any such Event of
Default, Collateral Agent shall have the rights of a secured creditor under the
UCC, all rights granted by this Security Agreement and by law, including the
right to:  (a) require each Debtor
to assemble the Collateral and make it available to Collateral Agent and the
Purchasers at a place to be designated by Collateral Agent and the Purchasers;
and (b) prior to the disposition of the Collateral, store, process, repair
or recondition it or otherwise prepare it for disposition in any manner and to
the extent Collateral Agent and the Purchasers deem appropriate. Each Debtor
hereby agrees that ten (10) days’ notice of any intended sale or
disposition of any Collateral is reasonable. In furtherance of Collateral Agent’s
rights hereunder, each Debtor hereby grants to Collateral Agent an irrevocable,
non-exclusive license, exercisable without royalty or other payment by
Collateral Agent, and only in connection with the exercise of remedies
hereunder, to use, license or sublicense any patent, trademark, trade name,
copyright or other intellectual property in which such Debtor now or hereafter
has any right, title or interest together with the right of access to all media
in which any of the foregoing may be recorded or stored.

 

E-6

 

(c)                                  Application of Collateral Proceeds. The proceeds and/or avails of the
Collateral, or any part thereof, and the proceeds and the avails of any
remedy hereunder (as well as any other amounts of any kind held by Collateral
Agent at the time of, or received by Collateral Agent after, the occurrence of
an Event of Default) shall be paid to and applied as follows:

 

(i)                                     First, to the payment of reasonable costs and expenses, including all
amounts expended to preserve the value of the Collateral, of foreclosure or
suit, if any, and of such sale and the exercise of any other rights or
remedies, and of all proper fees, expenses, liability and advances, including
reasonable legal expenses and attorneys’ fees, incurred or made hereunder by
Collateral Agent;

 

(ii)                                  Second, to the payment to each Purchaser of the amount then owing or unpaid
on such Purchaser’s Note, and in case such proceeds shall be insufficient to
pay in full the whole amount so due, owing or unpaid upon such Note, then its
Pro Rata Share of the amount remaining to be distributed (to be applied first
to accrued interest and second to outstanding principal);

 

(iii)                               Third, to the payment of other amounts then payable to each Purchaser under
any of the Transaction Documents, and in case such proceeds shall be
insufficient to pay in full the whole amount so due, owing or unpaid under such
Transaction Documents, then its Pro Rata Share of the amount remaining to be
distributed; and

 

(iv)                              Fourth, to the payment of the surplus, if any, to the Debtor, its successors
and assigns, or to whomsoever may be lawfully entitled to receive the
same.

 

For purposes of this Security Agreement, the term “Pro
Rata Share” shall mean, when calculating a Purchaser’s portion of any
distribution or amount, that distribution or amount (expressed as a percentage)
equal to a fraction (i) the numerator of which is the original outstanding
principal amount of such Purchaser’s Note and (ii) the denominator of
which is the original aggregate outstanding principal amount of all Notes
issued under the Purchase Agreement. In the event that a Purchaser receives
payments or distributions in excess of its Pro Rata Share, then such Purchaser
shall hold in trust all such excess payments or distributions for the benefit
of the other Purchasers and shall pay such amounts held in trust to such other
Purchasers upon demand by such Purchasers.

 

10.                                 Collateral Agent.

 

(a)                                  Appointment. The Purchasers hereby appoint [RockPort Capital Partners II, L.P.] as
collateral agent for the Purchasers under this Security Agreement (in such
capacity, the “Collateral Agent”)
to serve from the date hereof until the termination of the Security Agreement.

 

(b)                                 Powers and Duties of Collateral Agent, Indemnity
by Purchasers.

 

(i)                                     Each Purchaser hereby irrevocably authorizes
the Collateral Agent to take such action and to exercise such powers hereunder
as provided herein or as requested in writing by the Purchasers of a Majority
in Interest in accordance with the terms hereof, together with such powers as
are reasonably incidental thereto. Collateral Agent may execute any of its
duties hereunder by or through agents or employees and shall be entitled to
request and act in reliance upon the advise of counsel concerning all matters
pertaining to its duties hereunder and shall not be liable for any action taken
or omitted to be taken by it in good faith in accordance therewith.

 

E-7

 

(ii)                                  Neither the Collateral Agent nor any of its
directors, officers or employees shall be liable or responsible to any
Purchaser or to the Debtors for any action taken or omitted to be taken by
Collateral Agent or any other such person hereunder or under any related
agreement, instrument or document, except in the case of gross negligence or
willful misconduct on the part of the Collateral Agent, nor shall the
Collateral Agent or any of its directors, officers or employees be liable or
responsible for (i) the validity, effectiveness, sufficiency,
enforceability or enforcement of the Notes, this Security Agreement or any
instrument or document delivered hereunder or relating hereto; (ii) the
title of the Debtors to any of the Collateral or the freedom of any of the
Collateral from any prior or other liens or security interests; (iii) the
determination, verification or enforcement of each Debtor’s compliance with any
of the terms and conditions of this Security Agreement; (iv) the failure
by a Debtor to deliver any instrument  or
document required to be delivered pursuant to the terms hereof; or (v) the
receipt, disbursement, waiver, extension or other handling of payments or
proceeds made or received with respect to the collateral, the servicing of the
Collateral or the enforcement or the collection of any amounts owing with
respect to the Collateral.

 

(iii)                               In the case of this Security Agreement and the transactions
contemplated hereby and any related document relating to any of the Collateral,
each of the Purchasers agrees to pay to the Collateral Agent, on demand, its
Pro Rata Share of all fees and all expenses incurred in connection with the
operation and enforcement of this Security Agreement, the Notes or any related
agreement to the extent that such fees or expenses have not been paid by the
Debtors. In the case of this Security Agreement 
and each instrument and document relating to any of the Collateral, each
of the Purchasers and the Debtors hereby agree to hold the Collateral Agent
harmless, and to indemnify the Collateral Agent from and against any and all
loss, damage, expense or liability which may be incurred by the Collateral
Agent under this Security Agreement and the transactions contemplated hereby
and any related agreement or other instrument or document, as the case may be,
unless such liability shall be caused by the willful misconduct or gross
negligence of the Collateral Agent.

 

11.                                 Miscellaneous.

(b)                                 Termination of Security Interest. Upon the payment in full of all
Obligations, the security interest granted herein shall terminate and all
rights to the Collateral shall revert to the respective Debtor. Upon such
termination Collateral Agent hereby authorizes the Debtors to file any UCC
termination statements necessary to effect such termination and Collateral
Agent will, at such Debtor’s expense, execute and deliver to such Debtor any
additional documents or instruments as such Debtor shall reasonably request to
evidence such termination.

 

(c)                                  Nonwaiver. No failure or delay on Collateral Agent’s part in exercising any
right hereunder shall operate as a waiver thereof or of any other right nor
shall any single or partial exercise of any such right preclude any other
further exercise thereof or of any other right.

 

(d)                                 Amendments and Waivers. This Security Agreement may not be
amended or modified, nor may any of its terms be waived, except by written
instruments signed by the Debtors and Collateral Agent. Each waiver or consent
under any provision hereof shall be effective only in the specific instances
for the purpose for which given.

 

(e)                                  Assignments. This Security Agreement shall be binding upon and inure to the
benefit of Collateral Agent and the Debtors and their respective successors and
assigns; provided, however, that no Debtor may sell, assign
or delegate rights and obligations hereunder without the prior written consent
of Collateral Agent.

 

(f)                                    Cumulative Rights, etc. The rights, powers and remedies of Collateral
Agent under this Security Agreement shall be in addition to all rights, powers
and remedies given to Collateral Agent by 

 

E-9

 

virtue
of any applicable law, rule or regulation of any governmental authority,
any Transaction Document or any other agreement, all of which rights, powers,
and remedies shall be cumulative and may be exercised successively or
concurrently without impairing Collateral Agent’s rights hereunder. Each Debtor
waives any right to require Collateral Agent to proceed against any person or
entity or to exhaust any Collateral or to pursue any remedy in Collateral Agent’s
power.

 

(g)                                 Payments Free of Taxes, Etc. All payments made by each Debtor under the
Transaction Documents shall be made by such Debtor free and clear of and
without deduction for any and all present and future taxes, levies, charges,
deductions and withholdings. In addition, each Debtor shall pay upon demand any
stamp or other taxes, levies or charges of any jurisdiction with respect to the
execution, delivery, registration, performance and enforcement of this Security
Agreement. Upon request by Collateral Agent, each Debtor shall furnish evidence
satisfactory to Collateral Agent that all requisite authorizations and
approvals by, and notices to and filings with, governmental authorities and
regulatory bodies have been obtained and made and that all requisite taxes,
levies and charges have been paid.

 

(h)                                 Partial Invalidity. If at any time any provision of this
Security Agreement is or becomes illegal, invalid or unenforceable in any
respect under the law or any jurisdiction, neither the legality, validity or enforceability
of the remaining provisions of this Security Agreement nor the legality,
validity or enforceability of such provision under the law of any other
jurisdiction shall in any way be affected or impaired thereby.

 

(i)                                     Expenses. Each Debtor shall pay on demand all fees and expenses, including
reasonable attorneys’ fees and expenses, incurred by Collateral Agent in
connection with custody, preservation or sale of, or other realization on, any
of the Collateral or the enforcement or attempt to enforce any of the
Obligations which is not performed as and when required by this Security
Agreement.

 

(j)                                     Construction. Each of this Security Agreement and the
other Transaction Documents is the result of negotiations among, and has been
reviewed by, the Debtors, Purchasers, Collateral Agent and their respective
counsel. Accordingly, this Security Agreement and the other Transaction
Documents shall be deemed to be the product of all parties hereto, and no
ambiguity shall be construed in favor of or against the Debtors, Purchasers or
Collateral Agent.

 

(k)                                  Entire Agreement. This Security Agreement taken together with
the other Transaction Documents constitute and contain the entire agreement of
the Debtors, Purchasers and Collateral Agent and supersede any and all prior
agreements, negotiations, correspondence, understandings and communications
among the parties, whether written or oral, respecting the subject matter

additional
securities of any Issuer hereafter acquired by Debtor (collectively, with the

(c)                                  All proceeds of the foregoing (“Proceeds”).

 

3.                                       Security for Obligations. The obligations secured by this Pledge
Agreement (the “Obligations”) shall mean and include all loans,
advances, debts, liabilities and obligations, howsoever arising, owed by
Company to Collateral Agent and the Purchasers of every kind and description
(whether or not evidenced by any note or instrument and whether or not for the
payment of money), now existing or hereafter arising under or pursuant to the
terms of the Note Purchase Agreement, the Notes and the other Transaction

Statements. All certificates
or instruments representing or evidencing the Pledged Collateral shall be
promptly delivered to Collateral Agent and shall be in suitable form for
transfer by delivery, or shall be accompanied by duly executed assignment in
blank, in the form attached as Exhibit A hereto.

 

5.                                       Representations and Warranties. Debtor hereby represents and warrants as
follows:

 

(a)                                  Issuance of Pledged Securities, Etc. The Pledged Securities are owned by Debtor
free and clear of any and all liens, pledges, encumbrances or charges, and
Debtor has not optioned or otherwise agreed to sell, hypothecate, pledge, or
otherwise encumber or dispose of the Pledged Securities.

 

(b)                                 Security Interest. The pledge of the Pledged Collateral
creates a valid security interest in the Pledged Collateral, which security
interest is a perfected and first priority security interest, securing the
payment of the Obligations and the obligations hereunder.

 

(c)                                  Restatement of Representations and Warranties. On and as of the date any property becomes
Pledged Collateral, the foregoing representations and warranties shall be
deemed restated with respect to such additional Pledged Collateral.

 

6.                                       Further Assurances. Debtor agrees that at any time and from
time to time, at Debtor’s expense, Debtor will promptly execute and deliver all
further instruments and documents, including without limitation all additional
Pledged Securities, and take all further action, that may be necessary or
desirable, or that Collateral Agent may reasonably request, in order to
perfect and protect any security interest granted or purported to be granted
hereby or to enable Collateral Agent to exercise and enforce its rights and
remedies hereunder with respect to any Pledged Collateral.

7.                                       Voting Rights; Dividends; Etc.

 

(a)                                  Rights Prior to an Event of Default. So long as no Event of Default shall have
occurred and be continuing:

 

(i)                                     Debtor shall be entitled to exercise any and
all voting and other consensual rights pertaining to the Pledged Securities or
any part thereof for any purpose not inconsistent with the terms of this
Pledge Agreement.

 

(ii)                                  Debtor shall be entitled to receive and
retain free any and all dividends and interest paid in respect of the Pledged
Securities, provided, however, that any and all (A) dividends and interest
paid or payable other than in cash in respect of, and instruments and other
property received, receivable or otherwise distributed in respect of, or in
exchange for any Pledged Securities, (B) dividends and other distributions
paid or payable in cash in respect of any Pledged Securities in connection with
a partial or total liquidation or dissolution or in connection with a reduction
of capital, capital surplus or paid-in-surplus, and (C) cash paid, payable
or otherwise distributed in respect of principal of, or in redemption of, or in
exchange for, any Pledged Securities, shall be, and shall be forthwith
delivered to Collateral Agent to hold as, Pledged Collateral and shall, if
received by Debtor, be received in trust for the benefit of Collateral Agent,
be segregated from the other property or funds of Debtor and be forthwith
delivered to Collateral Agent as Pledged Collateral in the same form as so
received (with any necessary endorsement) to be held as part of the
Pledged Collateral.

 

(b)                                 Rights Following an Event of Default. Upon the occurrence and during the
continuance of an Event of Default:

 

(i)                                     All rights of Debtor to exercise the voting
and other consensual rights which it would otherwise be entitled to exercise
pursuant to Section 7(a)(i) and to receive the dividends and interest
payments which it would otherwise be authorized to receive and retain pursuant
to Section 7(a)(ii) shall cease and all such rights shall thereupon
become vested in Collateral Agent which shall thereupon have the sole right,
but not the obligation, to exercise such voting and other consensual rights and
to receive and hold as Pledged Collateral such dividends and interest payments.

 

(ii)                                  All dividends and interest payments which are
received by Debtor contrary to the provisions of subparagraph (i) of
this Section 7(b) shall be received in trust for the benefit of
Collateral Agent, shall be segregated from other funds of Debtor and shall be
forthwith delivered to Collateral Agent as Pledged Collateral in the same form as
so received (with any necessary endorsement).

 

8.                                       Events of Default; Remedies.

 

(a)                                  Event of Default. An Event of Default shall be deemed to have
occurred under this Pledge Agreement upon the occurrence and during the
continuance of an Event of Default under the Notes.

 

(b)                                 Rights Under the UCC. In addition to all other rights granted
hereby, and otherwise by law, Collateral Agent shall have, with respect to the
Pledged Collateral, the rights and obligations of a secured party under the
UCC.

 

(c)                                  Sale of Pledged Collateral. Debtor acknowledges and recognizes that
Collateral Agent may be unable to effect a public sale of all or a part of
the Pledged Securities and may be compelled to resort to one or more
private sales to a restricted group of purchasers who will be obligated to
agree, among other things, to acquire the Pledged Securities for their own
account, for investment and not with a view to the 

 

F-3

 

distribution
or resale thereof. Debtor acknowledges that any such private sales may be
at prices and on terms less favorable to Collateral Agent than those of public
sales, and agrees that so long as such sales are made in good faith such
private sales shall be deemed to have been made in a commercially reasonable
manner and that Collateral Agent has no obligation to delay sale of any Pledged
Securities to permit the issuer thereof to register it for public sale under
the Securities Act of 1933, as amended or under any state securities law.

 

(d)                                 Compliance with the Exchange Act. Upon the occurrence of an Event of Default
and at Collateral Agent’s request, Debtor agrees to use Debtor’s best efforts
to cause Issuer to disseminate publicly all information required to be
disseminated pursuant to the Securities Exchange Act of 1934, as amended, in
the event that Issuer or Debtor is required to file reports under such Act, or
to otherwise make available such information as to permit the public or private
sale of the Pledged Collateral in accordance with the terms of this Pledge
Agreement. Debtor further agrees to use Debtor’s best efforts to cause Issuer
to cooperate with Collateral Agent in taking whatever additional action may be
required to effect such public or private sale of the Pledged Collateral.

 

(e)                                  Notice, Etc. In any case where notice of sale is
required, ten (10) days’ notice shall be deemed reasonable notice. Collateral
Agent may have resort to the Pledged Collateral or any portion thereof
with no requirement on the part of Collateral Agent to proceed first
against any other Person or property.

 

(f)                                    Other Remedies. Upon the occurrence and during the
continuance of an Event of Default, (i) at the request of Collateral
Agent, Debtor shall assemble and make available to Collateral Agent all records
relating to the Pledged Securities at any place or places specified by
Collateral Agent, together with such other information as Collateral Agent
shall request concerning Debtor’s ownership of the Pledged Securities and
relationship to Issuer; and (ii) Collateral Agent or its nominee shall
have the right, but shall not be obligated, to vote or give consent with
respect to the Pledged Securities or any part thereof.

 

9.                                       Collateral Agent Appointed Attorney-in-Fact.

 

Debtor hereby appoints Collateral Agent as Debtor’s
attorney-in-fact, with full authority in the place and stead of Debtor and in
the name of Debtor or otherwise, from time to time in Collateral Agent’s
discretion and to the full extent permitted by law to take any action and to
execute any instrument which Collateral Agent may deem reasonably
necessary or advisable to accomplish the purposes of this Pledge Agreement in
accordance with the terms and provisions hereof, including without limitation,
to receive, endorse and collect all instruments made payable to Debtor
representing any dividend, interest payment or other distribution in respect of
the Pledged Collateral or any part thereof and to give full discharge for
the same.

 

Debtor hereby ratifies all reasonable actions that
said attorney shall lawfully do or cause to be done by virtue hereof. This
power of attorney is a power coupled with an interest and shall be irrevocable.
The powers conferred on Collateral Agent hereunder are solely to protect its
interests in the Pledged Collateral and shall not impose any duty upon
Collateral Agent to exercise any such powers. Collateral Agent shall be
accountable only for amounts that it actually receives as a result of the
exercise of such powers and in no event shall Collateral Agent or any of its
officers, directors, employees or agents be responsible to Debtor for any act
or failure to act, except for gross negligence or willful misconduct.

the Collateral Agent to take such action and to exercise such powers hereunder
as provided herein or as requested in writing by the Purchasers of a Majority
in Interest in accordance with the terms hereof, together with such powers as
are reasonably incidental thereto. Collateral Agent may execute any of its
duties hereunder by or through agents or employees and shall be entitled to
request and act in reliance upon the advise of counsel concerning all matters
pertaining to its duties hereunder and shall not be liable for any action taken
or omitted to be taken by it in good faith in accordance therewith.

 

(ii)                                  Neither the Collateral Agent nor any of its
directors, officers or employees shall be liable or responsible to any
Purchaser or to Company for any action taken or omitted to be taken by
Collateral Agent or any other such person hereunder or under any related
agreement, instrument or document, except in the case of gross negligence or
willful misconduct on the part of the Collateral Agent, nor shall the
Collateral Agent or any of its directors, officers or employees be liable or
responsible for (i) the validity, effectiveness, sufficiency,
enforceability or enforcement of the Notes, this Pledge Agreement or any
instrument or document delivered hereunder or relating hereto; (ii) the
title of Company to any of the Collateral or the freedom of any of the
Collateral from any prior or other liens or security interests; (iii) the

receipt, disbursement, waiver, extension or other handling of payments or
proceeds made or received with respect to the collateral, the servicing of the
Collateral or the enforcement or the collection of any amounts owing with
respect to the Collateral.

 

(iii)                               In the case of this Pledge Agreement and the transactions contemplated
hereby and any related document relating to any of the Collateral, each of the

(as defined in the Security Agreement) of all fees and all expenses incurred in
connection with the operation and enforcement of this Pledge Agreement, the
Notes or any related agreement to the extent that such fees or expenses have
not been paid by Company. In the case of this Pledge Agreement  and each instrument and document relating to
any of the Collateral, each of the Purchasers and the Company hereby agrees to
hold the Collateral Agent harmless, and to indemnify the Collateral Agent from
and against any and all loss, damage, expense or liability which may be
incurred by the Collateral Agent under this Pledge Agreement and the
transactions contemplated hereby and any related agreement or other instrument
or document, as the case may be, unless such liability shall be caused by
the willful misconduct or gross negligence of the Collateral Agent.

shall any single or partial exercise of any such right preclude any other
further exercise thereof or of any other right.

 

(c)                                  Amendments and Waivers. This Pledge Agreement may not be

require Collateral Agent to proceed against any Person or to exhaust any

levies and charges have been paid.

 

(g)                                 Partial Invalidity. If any time any provision of this Pledge
Agreement is or becomes illegal, invalid or unenforceable in any respect under

Agent’s rights and remedies (including, without limitation, all such fees and
expenses incurred in connection with any “workout” or restructuring affecting

Section 1, the Extended Maturity Date for all purposes under the Loan Documents
shall instead mean the Second Extended Maturity Date.  All terms and conditions of the Loan
Documents shall apply to the extended term. 
This Section 1 shall supercede any provisions in Section 2.13 or 10.01
of the Agreement to the contrary.
