under this Agreement, the Notes, the Purchase Agreement and any other instruments, agreements or
other documents executed and/or delivered in connection herewith or therewith, in each case,
whether now or hereafter existing, voluntary or involuntary, direct or indirect, absolute or
contingent, liquidated or unliquidated, whether or not jointly owed with others, and whether or not
from time to time decreased or extinguished and later increased, created or incurred, and all or
any portion of such obligations or liabilities that are paid, to the extent all or any part of such
payment is avoided or recovered directly or indirectly from the Collateral Agent as a preference,
fraudulent transfer or otherwise as such obligations may be amended, supplemented, converted,
extended or modified from time to time. Without limiting the generality of the foregoing, the term
“Obligations” shall include, without limitation: (i) principal of, and interest on, and any premium

be deemed to have guaranteed the Obligations of the Debtor and is referred to herein as a
"Guarantor”) in accordance with the terms hereof and any other instruments, agreements or
other documents executed and/or delivered in connection herewith or therewith; and (iii) all

(h) “UCC” means the Uniform Commercial Code of the State of Delaware and/or
any other applicable law of any state or states which have jurisdiction with respect to all, or any
portion of, the Collateral or this Agreement, from time to time. It is the intent of the parties
that defined terms in the UCC should be construed in their broadest sense so that the term
“Collateral” will be construed in its broadest sense. Accordingly if there are, from time to time,
changes to defined terms in the UCC that broaden the definitions, they are incorporated herein, and
if existing definitions in the UCC are broader than the amended definitions, the existing ones
shall be controlling.

2. Grant of Security Interest in Collateral. As an inducement for the Investors to
extend the loans as evidenced by the Notes and to secure the complete and timely payment,
performance and discharge in full, as the case may be, of all of the Obligations, the Debtor hereby
unconditionally and irrevocably pledges, grants and hypothecates to the Collateral Agent a security
interest in and to, a lien upon, and a right of set-off against, all of its respective right, title
and interest of whatsoever kind and nature in and to the Collateral (a “Security Interest”
and collectively, the “Security Interests”). To the extent there is at any time more than
one Collateral Agent hereunder, the Collateral will secure the Obligations to the Collateral Agent
on a pari passu basis, based on the then outstanding amount of such Obligations.

3. Delivery of Certain Collateral. If a direct or indirect subsidiary of the Debtor
is formed, the Debtor shall take all actions required by Section 3.15 of the Purchase Agreement
and/or Section 4(ii) of this Agreement within five (5) business days of such formation. In each
case, the Debtor shall deliver or cause to be delivered to the Collateral Agent (a) any and all
certificates and other instruments representing or evidencing the Pledged Securities, and (b) any
and all certificates and other instruments or documents representing any of the other Collateral,
in each case, together with all Necessary Endorsements. The Debtor shall deliver to the Collateral
Agent true and correct copy of each Organizational Document governing any of the Pledged
Securities. Throughout the term of this Agreement, so long as no Event of Default is uncured and
continuing, the Debtor shall have the right to vote the Pledged Securities in all matters presented
to the stockholders of the Pledge Securities for vote thereon, except in a manner inconsistent with
the terms of this Agreement or detrimental to the interests of the Investors. The Collateral Agent
shall hold the Pledged Securities in the form in which the same are delivered herewith, unless
there shall occur an Event of Default. To the extent that the Collateral Agent (or the Investors)
shall not previously have taken, acquired, sold, transferred, disposed of or otherwise realized
value on the Pledged Securities in accordance with this Agreement, on the date on which the
Obligations have been indefeasibly discharged, any remaining security interest in the Pledged
Securities shall automatically terminate, cease to exist and be released, and the Collateral Agent
shall forthwith return any remaining Pledged Securities and irrevocably release such shares from
collateral.

4. Representations, Warranties, Covenants and Agreements of the Debtors. Except as
set forth under the corresponding section of the disclosure schedules delivered to the Collateral
Agent concurrently herewith (the “Disclosure Schedules”), which Disclosure Schedules shall
be deemed a part hereof, the Debtor represents and warrants to, and covenants and agrees with, the
Collateral Agent as follows:

(a) The Debtor has the requisite corporate, partnership, limited liability company
or other power and authority to enter into this Agreement and otherwise to carry out its
obligations hereunder. The execution, delivery and performance by Debtor of this Agreement and the
filings contemplated therein have been duly authorized by all necessary action on the part of
Debtor and no further action is required by the Debtor. This Agreement has been duly executed by
the Debtor. This Agreement constitutes the legal, valid and binding obligation of the Debtor,
enforceable against the Debtor in accordance with its terms except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization and similar laws of general
application relating to or affecting the rights and remedies of creditors and by general principles
of equity.

(b) The Debtor has no place of business or office where its books of account and
records are kept or places where Collateral is stored or located, except as set forth on
Schedule A attached hereto. The Debtor shall use its reasonable best efforts to provide to
the Collateral Agent, as soon as reasonably practicable following the closing under the Purchase
Agreement, a landlord access agreement in customary form. Except as disclosed on Schedule
A, none of such Collateral is in the possession of any consignee, bailee, warehouseman, agent
or processor.

(c) Except as set forth on Schedule B attached hereto, the Debtors are the
sole owners of the Collateral, free and clear of any liens, security interests, encumbrances,
rights or claims, and are fully authorized to grant the Security Interests. There is not on file
in any governmental or regulatory authority, agency or recording office an effective financing
statement, security agreement, license or transfer or any notice of any of the foregoing (other
than those that will be filed in favor of the Collateral Agent pursuant to this Agreement) covering
or affecting any of the Collateral. As long as this Agreement shall be in effect, the Debtor shall
not execute and shall not permit to be on file in any such office or agency any other financing
statement or other similar document or instrument (except to the extent filed or recorded in favor
of the Collateral Agent pursuant to the terms of this Agreement).

(d) No written claim has been received by the Debtor that any Collateral or Debtor’s
use of any Collateral violates the rights of any third party. There has been no adverse decision
to the Debtor’s claim of ownership rights in or exclusive rights to use the Collateral in any
jurisdiction or to the Debtor’s right to keep and maintain such Collateral in full force and
effect, and there is no proceeding involving said rights pending or, to the best knowledge of the
Debtor, threatened before any court, judicial body, administrative or regulatory agency, arbitrator
or other governmental authority.

(e) The Debtor shall at all times maintain its books of account and records relating
to the Collateral at its principal place of business (except when temporarily kept at the offices
of its attorneys or accountants) and its Collateral at the locations set forth on Schedule
A attached hereto and may not relocate such books of account and records or tangible Collateral
unless it delivers to the Collateral Agent at least 30 days prior to such relocation (i) written
notice of such relocation and the new location thereof (which must be within the United States) and
(ii) evidence that appropriate financing statements under the UCC and other necessary documents
have been filed and recorded and other steps have been taken to perfect the Security Interests to
create in favor of the Collateral Agent a valid, perfected and continuing perfected first priority
lien in the Collateral.

(f) This Agreement creates in favor of the Collateral Agent a valid, security
interest in the Collateral securing the payment and performance of the Obligations subject to no
other liens or security interests except as set forth on Schedule B. Upon making the
filings described in the immediately following paragraph, all security interests created hereunder
in any Collateral which may be perfected by filing UCC financing statements shall have been duly
perfected. Except for the filing of the UCC financing statements referred to in the immediately
following paragraph and the recordation of the Intellectual Property Security Agreement (as defined
below) with respect to the Intellectual Property listed in Schedule G in the United States
Patent and Trademark Office, no action is necessary to create, perfect or protect the security
interests created hereunder. Without limiting the generality of the foregoing, except for the
filing of said financing statements and the recordation of said Intellectual Property Security
Agreement, no consent of any third parties and no authorization, approval or other action by, and
no notice to or filing with, any governmental authority or regulatory body is required for (i) the
execution, delivery and performance of this Agreement, (ii) the creation or perfection of the
Security Interests created hereunder in the Collateral or (iii) the enforcement of the rights of
the Collateral Agent hereunder.

(g) The Debtor hereby authorizes the Collateral Agent to file one or more financing
statements under the UCC with respect to the Security Interests with the proper filing and
recording agencies in any jurisdiction deemed proper by it, which UCC financing statement may
describe the collateral as “All assets”.

(h) The execution, delivery and performance of this Agreement by the Debtors do not
(i) violate any of the provisions of any Organizational Documents of any Debtor or any judgment,
decree, order or award of any court, governmental body or arbitrator or any applicable law, rule or
regulation applicable to any Debtor or (ii) conflict with, or constitute a default (or an event
that with notice or lapse of time or both would become a default) under, or give to others any
rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of
time or both) of, any agreement, credit facility, debt or other instrument (evidencing any Debtor’s
debt or otherwise) or other understanding to which any Debtor is a party or by which any property
or asset of any Debtor is bound or affected. If any, all required consents (including, without
limitation, from stockholders or creditors of any Debtor) necessary for any Debtor to enter into
and perform its obligations hereunder have been obtained.

(i) The capital stock and other equity interests in each of the Guarantors (the
“Pledged Securities”) shall be pledged as required herein and in Section 3.15 of the
Purchase Agreement and shall represent all of the capital stock and other equity interests in and
to the Guarantors and shall represent all capital stock and other equity interests owned, directly
or indirectly, by the Debtor. All of the Pledged Securities shall be validly issued, fully paid
and nonassessable, and the Debtor shall be the legal and beneficial owner of the Pledged
Securities, free and clear of any lien, security interest or other encumbrance except for the
security interests created by this Agreement or as otherwise set forth on Schedule B. The
Debtor shall cause the pledge and security interest of the Collateral Agent to be duly noted in its
corporate books and records.

(j) The ownership and other equity interests in partnerships and limited liability
companies (if any) included in the Collateral (the “Pledged Interests”) by their express
terms shall not provide that they are securities governed by Article 8 of the UCC and shall not be
held in a securities account or by any financial intermediary.

(k) The Debtor shall at all times maintain the liens and Security Interests provided
for hereunder as valid and perfected first priority liens and security interests in the Collateral
in favor of the Collateral Agent until this Agreement and the Security Interests hereunder shall be
terminated pursuant to Section 14 hereof. The Debtor hereby agrees to use commercially reasonable
efforts to defend the same against the claims of any and all persons and entities and to safeguard
and protect all Collateral for the account of the Collateral Agent. At the reasonable request of
the Collateral Agent, the Debtor will sign and deliver to the Collateral Agent at any time or from
time to time one or more financing statements pursuant to the UCC in form reasonably satisfactory
to the Collateral Agent and will pay the cost of filing the same in all public offices wherever
filing is necessary to effect the rights and obligations provided for herein. Without limiting the
generality of the foregoing, the Debtor shall pay all fees, taxes and other amounts necessary to
maintain the Collateral and the Security Interests hereunder, and the Debtor shall obtain and
furnish to the Collateral Agent from time to time, upon demand, such releases and/or subordinations
of claims and liens which may be required to maintain in accordance with this Agreement the
priority of the Security Interests hereunder.

(l) The Debtor will not transfer, pledge, hypothecate, encumber, license, sell or
otherwise dispose of any of the Collateral (except for sales of inventory by the Debtor in its
ordinary course of business) without the prior written consent of the Collateral Agent.

(m) The Debtor shall keep and preserve its equipment, inventory and other tangible
Collateral in good condition, repair and order and shall not operate or locate any such Collateral
(or cause to be operated or located) in any area excluded from insurance coverage.

(n) The Debtor shall maintain with financially sound and reputable insurers,
insurance with respect to the Collateral, including Collateral hereafter acquired, against loss or
damage of the kinds and in the amounts customarily insured against by entities of established
reputation having similar properties similarly situated and in such amounts as are customarily
carried under similar circumstances by other such entities and otherwise as is prudent for entities
engaged in similar businesses but in any event sufficient to cover the full replacement cost
thereof. The Debtor shall cause each insurance policy issued in connection herewith to provide,
and the insurer issuing such policy to certify to the Collateral Agent that (a) the Collateral
Agent will be named as lender loss payee and additional insured under each such insurance policy;
(b) if such insurance be proposed to be cancelled or materially changed for any reason whatsoever,
such insurer will promptly notify the Collateral Agent and such cancellation or change shall not be
effective as to the Collateral Agent for at least thirty (30) days after receipt by the Collateral
Agent of such notice, unless the effect of such change is to extend or increase coverage under the
policy; and (c) the Collateral Agent will have the right (but no obligation) at its election to
remedy any default in the payment of premiums within thirty (30) days of notice from the insurer of
such default. If no Event of Default (as defined in the Notes) exists and if the proceeds arising
out of any claim or series of related claims do not exceed $10,000, loss payments in each instance
will be applied by the applicable Debtor to the repair and/or replacement of property with respect
to which the loss was incurred to the extent reasonably feasible, and any loss payments or the
balance thereof remaining, to the extent not so applied, shall be payable to the applicable Debtor,
provided, however, that payments received by any Debtor after an Event of Default occurs and is
continuing or in excess of $10,000 for any occurrence or series of related occurrences shall be
paid to the Collateral Agent and, if received by the Debtor, shall be held in trust for the
Collateral Agent and promptly paid over to the Collateral Agent unless otherwise directed in
writing by the Collateral Agent. Copies of such policies or the related certificates, in each
case, naming the Collateral Agent as lender loss payee and additional insured shall be delivered to
the Collateral Agent at least annually and at the time any new policy of insurance is issued.

(o) The Debtor shall, within ten (10) days of obtaining knowledge thereof, advise
the Collateral Agent promptly, in sufficient detail, of any material adverse change in the
Collateral, and of the occurrence of any event which would have a material adverse effect on the
value of the Collateral or on the Collateral Agent’s security interest therein.

(p) The Debtor shall promptly execute and deliver to the Collateral Agent such
further deeds, mortgages, assignments, security agreements, financing statements or other
instruments, documents, certificates and assurances and take such further action as the Collateral
Agent may from time to time request as necessary to perfect, protect or enforce the Collateral
Agent’s security interest in the Collateral (including, without limitation, the execution and
delivery of a separate security agreement with respect to the Debtor’s Intellectual Property
(“Intellectual Property Security Agreement”) to be delivered on the date hereof) in which
the Collateral Agent has been granted a security interest hereunder, substantially in a form
reasonably acceptable to the Collateral Agent.

(q) The Debtor shall permit the Collateral Agent and its representatives and agents
reasonable access to inspect the Collateral during normal business hours, upon reasonable prior
notice and without undue interference with the Debtor’s business operations, and to make copies of
records pertaining to the Collateral as may be reasonably requested by the Collateral Agent from
time to time.

(r) The Debtor shall take all steps reasonably necessary to diligently pursue and
seek to preserve, enforce and collect any rights, claims, causes of action and accounts receivable
in respect of the Collateral.

(s) The Debtor shall promptly notify the Collateral Agent in sufficient detail upon
becoming aware of any attachment, garnishment, execution or other legal process levied against any
Collateral and of any other information received by the Debtor that would have a material adverse
effect on the value of the Collateral, the Security Interest or the rights and remedies of the
Collateral Agent hereunder.

(t) All information heretofore, herein or hereafter supplied to the Collateral Agent
by or on behalf of any Debtor with respect to the Collateral is accurate and complete in all
material respects as of the date furnished.

(u) The Debtors shall at all times preserve and keep in full force and effect their
respective valid existence and good standing and any rights and franchises material to their
respective businesses.

(v) No Debtor will change its name, type of organization, jurisdiction of
organization, organizational identification number (if it has one), legal or corporate structure,
or identity, or add any new fictitious name unless it provides at least 30 days’ prior written
notice to the Collateral Agent of such change and, at the time of such written notification, the
Debtor provides any financing statements or fixture filings necessary to perfect and continue the
perfection of the Security Interests granted and evidenced by this Agreement.

(w) Except in the ordinary course of business, the Debtor may not consign any of its
Inventory or sell any of its Inventory on bill and hold, sale or return, sale on approval, or other
conditional terms of sale without the consent of the Collateral Agent, which shall not be
unreasonably withheld.

(x) The Debtor may not relocate its chief executive office to a new location without
providing 30 days’ prior written notification thereof to the Collateral Agent and providing to the
Collateral Agent, at the time of such written notification, any financing statements or fixture
filings necessary to perfect and continue the perfection of the Security Interests granted and
evidenced by this Agreement.

(y) The Debtor was organized and remains organized solely under the laws of the

(aa) At any time and from time to time that any Collateral consists of instruments,
certificated securities or other items that require or permit possession by the secured party to
perfect the security interest created hereby, the Debtor shall deliver such Collateral to the
Collateral Agent.

(bb) The Debtor, in its capacity as issuer, hereby agrees to comply with any and all
reasonable orders and instructions of Collateral Agent regarding the Pledged Interests consistent
with the terms of this Agreement without the further consent of any other party as contemplated by
Section 8-106 (or any successor section) of the UCC. Further, the Debtor agrees that it shall not
enter into a similar agreement (or one that would confer “control” within the meaning of Article 8
of the UCC) with any other person or entity.

(cc) The Debtor shall cause all tangible chattel paper constituting Collateral to be
delivered to the Collateral Agent, or, if such delivery is not possible, then to cause such
tangible chattel paper to contain a legend noting that it is subject to the security interest

the proceeds thereof to the Collateral Agent.

(ff) To the extent that any Collateral is in the possession of any third party, the
Debtor shall join with the Collateral Agent in notifying such third party of the Collateral Agent’s
security interest in such Collateral and shall endeavor to obtain an acknowledgement and agreement
from such third party with respect to the Collateral, in form and substance reasonably satisfactory
to the Collateral Agent.

(gg) If the Debtor shall at any time hold or acquire a commercial tort claim, the
Debtor shall promptly notify the Collateral Agent in a writing signed by the Debtor of the
particulars thereof and grant to the Collateral Agent in such writing a security interest therein
and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form
and substance reasonably satisfactory to the Collateral Agent.

(hh) The Debtor shall promptly provide written notice to the Collateral Agent of any
and all accounts which arise out of contracts with any governmental authority and, to the extent
necessary to perfect or continue the perfected status of the Security Interests in such accounts
and proceeds thereof, shall execute and deliver to the Collateral Agent an assignment of claims for
such accounts and cooperate with the Collateral Agent in taking any other steps required under the
Federal Assignment of Claims Act or any similar federal, state or local statute or rule to perfect

As of the date hereof, the Debtor represents and warrants that it has no subsidiaries or equity
interests in third parties. Concurrent therewith, the Additional Debtor shall deliver replacement

financing statements and other information and documentation as the Collateral Agent may reasonably
request. Upon delivery of the foregoing to the Collateral Agent, the Additional Debtor shall be

purposes hereof as fully and to the same extent as if it were an original signatory hereto and
shall be deemed to have made the representations, warranties and covenants set forth herein as of
the date of execution and delivery of such Additional Debtor Joinder, and all references herein to
the “Debtor” shall be deemed to include each Additional Debtor.

(jj) The Debtor shall vote the Pledged Securities to comply with the covenants and
agreements set forth herein and in the Notes and the other Transaction Documents (as defined in the
Purchase Agreement).

(kk) The Debtor shall register the pledge of the applicable Pledged Securities on

pledge of the applicable Pledged Securities in the name of the Collateral Agent on the books of
such issuer. Further, except with respect to certificated securities delivered to the Collateral
Agent, the Debtor shall endeavor to deliver to the Collateral Agent an acknowledgement of pledge
(which, where appropriate, shall comply with the requirements of the relevant UCC with respect to
perfection by registration) signed by the issuer of the applicable Pledged Securities, which

(b) at any time directed by the Collateral Agent during the continuation of an Event of Default,
such issuer will transfer the record ownership of such Pledged Securities into the name of any
designee of the Collateral Agent, will take such steps as may be necessary to effect the transfer,
and will comply with all other reasonable instructions of the Collateral Agent regarding such
Pledged Securities without the further consent of the Debtor.

(ll) In the event that, upon an occurrence of an Event of Default, the Collateral
Agent shall sell all or any of the Pledged Securities to another party or parties (herein called
the “Transferee”) or shall purchase or retain all or any of the Pledged Securities, the
Debtor shall, to the extent applicable: (i) deliver to the Collateral Agent or the Transferee, as
the case may be, the articles of incorporation, bylaws, minute books, stock certificate books,
corporate seals, deeds, leases, indentures, agreements, evidences of indebtedness, books of
account, financial records and all other Organizational Documents and records of the Debtor and its
direct and indirect subsidiaries; (ii) use its best efforts to obtain resignations of the persons
then serving as officers and directors of the Debtor and its direct and indirect subsidiaries, if
so requested; and (iii) use its best efforts to obtain any approvals that are required by any
governmental or regulatory body in order to permit the sale of the Pledged Securities to the
Transferee or the purchase or retention of the Pledged Securities by the Collateral Agent and allow
the Transferee or Collateral Agent to continue the business of the Debtor and its direct and
indirect subsidiaries.

(mm) Without limiting the generality of the other obligations of the Debtor
hereunder, the Debtor shall promptly (i) cause to be registered at the United States Copyright
Office all of its material copyrights, (ii) cause the security interest contemplated hereby with
respect to all Intellectual Property registered at the United States Copyright Office or United
States Patent and Trademark Office to be duly recorded at the applicable office, and (iii) give the
Collateral Agent notice whenever it acquires (whether absolutely or by license) or creates any
additional material Intellectual Property.

(nn) The Debtor will from time to time, at the expense of the Debtor, promptly
execute and deliver all such further instruments and documents, and take all such further action as
may be necessary or desirable, or as the Collateral Agent may reasonably request, in order to
perfect and protect any security interest granted or purported to be granted hereby or to enable
the Collateral Agent to exercise and enforce its rights and remedies hereunder and with respect to
any Collateral or to otherwise carry out the purposes of this Agreement.

(oo) Schedule G attached hereto lists all of the patents, patent
applications, trademarks, trademark applications, registered copyrights, and domain names owned by
the Debtor as of the date hereof. Schedule G lists all material licenses in favor of the
Debtor for the use of any patents, trademarks, copyrights and domain names as of the date hereof.

(pp) Except as set forth on Schedule H attached hereto, none of the account
debtors or other persons or entities obligated on any of the Collateral is a governmental authority
covered by the Federal Assignment of Claims Act or any similar federal, state or local statute or
rule in respect of such Collateral.

(qq) The Debtor shall cause the landlord under the lease for its headquarter space
located at 3216 South Highland Drive, Salt Lake City, Utah 84106 and any other lease for premises
at which any of the Collateral is located to enter into and deliver to the Collateral Agent, no
later than 60 days from the date hereof, a landlord access agreement providing the Collateral Agent
with access to the Collateral located at such premises upon the occurrence of an Event of Default
on customary terms and conditions.

(rr)  Each inventor listed on patent application 11/437,001 has either validly
assigned its interest in the inventions and claims that are the subject of such patent application
to the Debtor or executed an agreement pursuant to which it has assigned or is obligated to assign
such interest to the Debtor.

5. Effect of Pledge on Certain Rights. If any of the Collateral subject to this
Agreement consists of nonvoting equity or ownership interests (regardless of class, designation,
preference or rights) that may be converted into voting equity or ownership interests upon the
occurrence of certain events (including, without limitation, upon the transfer of all or any of the
other stock or assets of the issuer), it is agreed that the pledge of such equity or ownership
interests pursuant to this Agreement or the enforcement of any of the Collateral Agent’s rights
hereunder shall not be deemed to be the type of event which would trigger such conversion rights
notwithstanding any provisions in the Organizational Documents or agreements to which the Debtor is
subject or to which the Debtor is party.

6. Defaults. The following events shall be “Events of Default”:

(a) The occurrence of an Event of Default under the Notes;

(b) Any representation or warranty of the Debtor in this Agreement shall prove to
have been incorrect in any material respect when made; or

(c) The failure by the Debtor to observe or perform any of its obligations hereunder
for five (5) business days after delivery to the Debtor of notice of such failure by or on behalf
of the Collateral Agent.

7. Duty To Hold In Trust.

(a) Upon the occurrence and during the continuance of any Event of Default and at
any time thereafter, the Debtor shall, upon receipt of any revenue, income, dividend, interest or
other sums subject to the Security Interests, whether payable pursuant to the Notes or otherwise,
or of any check, draft, note, trade acceptance or other instrument evidencing an obligation to pay
any such sum, hold the same in trust for the Collateral Agent and shall forthwith endorse and
transfer any such sums or instruments, or both, to the Collateral Agent.

(b) If the Debtor shall become entitled to receive or shall receive any securities
or other property (including, without limitation, shares of Pledged Securities or instruments
representing Pledged Securities acquired after the date hereof, or any options, warrants, rights or
other similar property or certificates representing a dividend, or any distribution in connection
with any recapitalization, reclassification or increase or reduction of capital, or issued in
connection with any reorganization of the Debtor or any of its direct or indirect subsidiaries) in
respect of the Pledged Securities (whether as an addition to, in substitution of, or in exchange
for, such Pledged Securities or otherwise), the Debtor agrees to (i) accept the same as the agent
of the Collateral Agent; (ii) hold the same in trust on behalf of and for the benefit of the
Collateral Agent; and (iii) deliver any and all certificates or instruments evidencing the same to
the Collateral Agent on or before the close of business on the fifth business day following the
receipt thereof by the Debtor, in the exact form received together with the Necessary Endorsements,
to be held by the Collateral Agent subject to the terms of this Agreement as Collateral.

8. Rights and Remedies Upon Default.

(a) Upon the occurrence of any Event of Default and at any time thereafter, the
Collateral Agent shall have the right to exercise all of the remedies conferred hereunder and under
the Notes, and the Collateral Agent shall have all the rights and remedies of a secured party under
the UCC. Without limitation, the Collateral Agent shall have the following rights and powers:

(i) The Collateral Agent shall have the right to take possession of the
Collateral and, for that purpose, enter by reasonable means, with the aid and assistance of
any person, any premises where the Collateral, or any part thereof, is or may be placed and
remove the same, and the Debtor shall assemble the Collateral and make it available to the
Collateral Agent at places which the Collateral Agent shall reasonably select, whether at
the Debtor’s premises or elsewhere, and make reasonably available to the Collateral Agent,
without rent, all of the Debtor’s respective premises and facilities for the purpose of the
Collateral Agent taking possession of, removing or putting the Collateral in saleable or
disposable form.

(ii) Upon written notice to the Debtor by the Collateral Agent, all rights of
the Debtor to exercise the voting and other consensual rights which it would otherwise be
entitled to exercise and all rights of the Debtor to receive the dividends and interest
which it would otherwise be authorized to receive and retain, shall cease. Upon such
notice, the Collateral Agent shall have the right to receive any interest, cash dividends or
other payments on the Collateral and, at the option of the Collateral Agent, to exercise in
the Collateral Agent’s discretion all voting rights pertaining thereto. Without limiting
the generality of the foregoing, the Collateral Agent shall have the right (but not the
obligation) to exercise all rights with respect to the Collateral as if it were the sole and
absolute owner thereof, including, without limitation, to vote and/or to exchange, at its
sole discretion, any or all of the Collateral in connection with a merger, reorganization,
consolidation, recapitalization or other readjustment concerning or involving the Collateral
or any Debtor or any of its direct or indirect subsidiaries.

(iii) The Collateral Agent shall have the right to assign, sell, lease or
otherwise dispose of and deliver all or any part of the Collateral, at public or private
sale or otherwise, either with or without special conditions or stipulations, for cash or on
credit or for future delivery, in such parcel or parcels and at such time or times and at
such place or places, and upon commercially reasonable terms and conditions. Upon each such
sale, lease, assignment or other transfer of Collateral, the Collateral Agent, may, unless
prohibited by applicable law which cannot be waived, purchase all or any part of the
Collateral being sold, free from and discharged of all trusts, claims, right of redemption
and equities of the Debtor, which are hereby waived and released.

(iv) The Collateral Agent shall have the right (but not the obligation) to
notify any account debtors and any obligors under instruments or accounts to make payments
directly to the Collateral Agent, and to enforce the Debtor’s rights against such account
debtors and obligors.

(v) The Collateral Agent, may (but is not obligated to) direct any financial
intermediary or any other person or entity holding any investment property to transfer the
same to the Collateral Agent, or its designee.

(vi) The Collateral Agent may (but is not obligated to) transfer any or all
Intellectual Property registered in the name of the Debtor at the United States Patent and
Trademark Office and/or Copyright Office into the name of the Collateral Agent or any
designee or any purchaser of any Collateral.

(b) The Collateral Agent shall comply with any applicable law in connection with a
disposition of Collateral and such compliance will not be considered adversely to affect the
commercial reasonableness of any sale of the Collateral. The Collateral Agent may sell the
Collateral without giving any warranties and may specifically disclaim such warranties. In
addition, the Debtor waives any and all rights that it may have to a judicial hearing in advance of
the enforcement of any of the Collateral Agent’s rights and remedies hereunder, including, without
limitation, its right following an Event of Default to take immediate possession of the Collateral
and to exercise its rights and remedies with respect thereto.

(c) For the purpose of enabling the Collateral Agent to further exercise rights and
remedies under this Section 8 or elsewhere provided by agreement or applicable law, the Debtor
hereby grants to the Collateral Agent, an irrevocable, nonexclusive license (exercisable without
payment of royalty or other compensation to the Debtor) to use, license or sublicense following an
Event of Default, any Intellectual Property now owned or hereafter acquired by the Debtor, and
wherever the same may be located, and including in such license access to all media in which any of
the licensed items may be recorded or stored and to all computer software and programs used for the
compilation or printout thereof.

9. Applications of Proceeds. The proceeds of any sale, lease or other disposition
of the Collateral hereunder or from payments made on account of any insurance policy insuring any
portion of the Collateral shall be applied as provided in, and in the order of priority set forth
in, Section 7.18 of the Purchase Agreement. Without limitation, the Collateral Agent shall be
entitled to apply such proceeds to pay or reimburse the Collateral Agent for the reasonable and
actually incurred expenses of retaking, holding, storing, processing and preparing for sale,
selling, and the like (including, without limitation, any taxes, fees and other costs reasonably
incurred in connection therewith) of the Collateral and to the reasonable attorneys’ fees and
expenses incurred by the Collateral Agent in enforcing the Collateral Agent’s rights hereunder and
in connection with collecting, storing and disposing of the Collateral. To the extent permitted by
applicable law, the Debtor waives all claims, damages and demands against the Collateral Agent
arising out of the repossession, removal, retention or sale of the Collateral, unless due solely to
the gross negligence or willful misconduct of the Collateral Agent as determined by a final
judgment (not subject to further appeal) of a court of competent jurisdiction.

10. Securities Law Provision. The Debtor recognizes that the Collateral Agent may
be limited in its ability to effect a sale to the public of all or part of the Pledged Securities
by reason of certain prohibitions in the Securities Act of 1933, as amended, or other federal or
state securities laws (collectively, the “Securities Laws”), and may be compelled to resort
to one or more sales to a restricted group of purchasers who may be required to agree to acquire
the Pledged Securities for their own account, for investment and not with a view to the
distribution or resale thereof. The Debtor agrees that sales so made may be at prices and on terms
less favorable than if the Pledged Securities were sold to the public, and that the Collateral
Agent has no obligation to delay the sale of any Pledged Securities for the period of time
necessary to register the Pledged Securities for sale to the public under the Securities Laws. The
Debtor shall cooperate with the Collateral Agent in its reasonable attempt to satisfy any
requirements under the Securities Laws (including, without limitation, registration thereunder if
reasonably requested by the Collateral Agent) applicable to the sale of the Pledged Securities by
the Collateral Agent.

11. Costs and Expenses. The Debtor agrees to pay all reasonable out-of-pocket fees,
costs and expenses incurred in connection with any filing required hereunder, including without
limitation, any financing statements pursuant to the UCC, continuation statements, partial releases
and/or termination statements related thereto or any expenses of any searches reasonably required
by the Collateral Agent. The Debtor shall also pay all other claims and charges which would be
reasonably likely to prejudice, imperil or otherwise affect the Collateral or the Security
Interests therein. The Debtor will also, upon demand, pay to the Collateral Agent the amount of
any and all reasonable expenses, including the reasonable fees and expenses of its counsel and of
any experts and agents, which the Collateral Agent, may incur in connection with (i) the
enforcement of this Agreement, (ii) the custody or preservation of, or the sale of, collection
from, or other realization upon, any of the Collateral, or (iii) the exercise or enforcement of any
of the rights of the Collateral Agent under the Notes and the other Transaction Documents. Until
so paid, any fees payable hereunder shall be added to the principal amount of the Notes and shall
bear interest at the Default Rate.

12. Responsibility for Collateral. The Debtor assumes all liabilities and
responsibility in connection with all Collateral, and the Obligations shall in no way be affected
or diminished by reason of the loss, destruction, damage or theft of any of the Collateral or its
unavailability for any reason. Without limiting the generality of the foregoing, (a) in no event
shall the Collateral Agent (i) have any duty (either before or after an Event of Default) to
collect any amounts in respect of the Collateral or to preserve any rights relating to the
Collateral, or (ii) have any obligation to clean-up or otherwise prepare the Collateral for sale,
and (b) the Debtor shall remain obligated and liable under each contract or agreement included in
the Collateral to be observed or performed by the Debtor thereunder. The Collateral Agent shall
not have any obligation or liability under any such contract or agreement by reason of or arising
out of this Agreement or the receipt by the Collateral Agent of any payment relating to any of the
Collateral, nor shall the Collateral Agent be obligated in any manner to perform any of the
obligations of the Debtor under or pursuant to any such contract or agreement, to make inquiry as
to the nature or sufficiency of any payment received by the Collateral Agent in respect of the
Collateral or as to the sufficiency of any performance by any party under any such contract or
agreement, to present or file any claim, to take any action to enforce any performance or to
collect the payment of any amounts which may have been assigned to the Collateral Agent or to which
the Collateral Agent may be entitled at any time or times.

13. Security Interests Absolute. All rights and all obligations of the parties
hereunder, shall be absolute and unconditional, irrespective of: (a) any lack of validity or
enforceability of this Agreement, the Notes or any agreement entered into in connection with the
foregoing, or any portion hereof or thereof; (b) any change in the time, manner or place of payment
or performance of, or in any other term of, all or any of the Obligations, or any other amendment
or waiver of or any consent to any departure from the Notes or any other agreement entered into in
connection with the foregoing; (c) any exchange, release or nonperfection of any of the Collateral,
or any release or amendment or waiver of or consent to departure from any other collateral for, or
any guarantee, or any other security, for all or any of the Obligations; (d) any action by the
Collateral Agent to obtain, adjust, settle and cancel in its reasonable discretion any insurance
claims or matters made or arising in connection with the Collateral; or (e) any other circumstance
which might otherwise constitute any legal or equitable defense available to the Debtor, or a
discharge of all or any part of the Security Interests granted hereby. Until the Obligations shall
have been paid and performed in full, the rights of the Collateral Agent shall continue even if the
Obligations are barred for any reason, including, without limitation, the running of the statute of
limitations or bankruptcy. The Debtor expressly waives presentment, protest, notice of protest,
demand, notice of nonpayment and demand for performance. In the event that at any time any
transfer of any Collateral or any payment received by the Collateral Agent hereunder shall be
deemed by final order of a court of competent jurisdiction to have been a voidable preference or
fraudulent conveyance under the bankruptcy or insolvency laws of the United States, or shall be
deemed to be otherwise due to any party other than the Collateral Agent, then, in any such event
and to the extent thereof, the Debtor’s obligations hereunder shall survive cancellation of this
Agreement, and shall not be discharged or satisfied by any prior payment thereof and/or
cancellation of this Agreement, but shall remain a valid and binding obligation enforceable in
accordance with the terms and provisions hereof. The Debtor waives all right to require the
Collateral Agent to proceed against any other person or entity or to apply any Collateral which the
Collateral Agent may hold at any time, or to marshal assets, or to pursue any other remedy.

14. Term of Agreement. This Agreement and the Security Interests shall terminate on
the date on which all payments under the Notes have been indefeasibly paid or otherwise satisfied
in full (including by way of conversion of the Notes) and all other Obligations have been paid or
discharged in full.

15. Power of Attorney; Further Assurances.

(a) The Debtor authorizes the Collateral Agent, and does hereby make, constitute and
appoint the Collateral Agent and its officers, agents, successors or assigns with full power of
substitution, as the Debtor’s true and lawful attorney-in-fact, with power, in the name of the
Collateral Agent or the Debtor, to, after the occurrence and during the continuance of an Event of
Default, (i) endorse any note, checks, drafts, money orders or other instruments of payment
(including payments payable under or in respect of any policy of insurance) in respect of the
Collateral that may come into possession of the Collateral Agent; (ii) to sign and endorse any
financing statement pursuant to the UCC or any invoice, freight or express bill, bill of lading,
storage or warehouse receipts, drafts against debtors, assignments, verifications and notices in
connection with accounts, and other documents relating to the Collateral; (iii) to pay or discharge
taxes, liens, security interests or other encumbrances at any time levied or placed on or
threatened against the Collateral; (iv) to demand, collect, receipt for, compromise, settle and sue
for monies due in respect of the Collateral; (v) to transfer any Intellectual Property or provide
licenses respecting any Intellectual Property; and (vi) generally, at the option of the Collateral
Agent, and at the expense of the Debtor, at any time, or from time to time, to execute and deliver
any and all documents and instruments and to do all acts and things which the Collateral Agent
deems necessary to protect, preserve and realize upon the Collateral and the Security Interests
granted therein in order to effect the intent of this Agreement and the Notes all as fully and
effectually as the Debtor might or could do; and the Debtor hereby ratifies all that said attorney
shall lawfully do or cause to be done by virtue hereof. This power of attorney is coupled with an
interest and shall be irrevocable for the term of this Agreement and thereafter as long as any of
the Obligations shall be outstanding. The designation set forth herein shall be deemed to amend
and supersede any inconsistent provision in the Organizational Documents or other documents or
agreements to which any Debtor is subject or to which any Debtor is a party. Without limiting the
generality of the foregoing, after the occurrence and during the continuance of an Event of
Default, the Collateral Agent is specifically authorized to execute and file any applications for
or instruments of transfer and assignment of any patents, trademarks, copyrights or other
Intellectual Property with the United States Patent and Trademark Office and the United States
Copyright Office.

(b) On a continuing basis, the Debtor will make, execute, acknowledge, deliver, file
and record, as the case may be, with the proper filing and recording agencies in any jurisdiction,
including, without limitation, the jurisdictions indicated on Schedule C attached hereto,
all such instruments, and take all such action as may reasonably be deemed necessary or advisable,
or as reasonably requested by the Collateral Agent, to perfect the Security Interests granted
hereunder and otherwise to carry out the intent and purposes of this Agreement, or for assuring and
confirming to the Collateral Agent the grant or perfection of a perfected security interest in all
the Collateral under the UCC.

(c) The Debtor hereby irrevocably appoints the Collateral Agent as the Debtor’s
attorney-in-fact, with full authority in the place and instead of the Debtor and in the name of the
Debtor, from time to time in the Collateral Agent’s discretion, to take any action and to execute
any instrument which the Collateral Agent may deem necessary or advisable to accomplish the
purposes of this Agreement, including the filing, in its sole discretion, of one or more financing
or continuation statements and amendments thereto, relative to any of the Collateral without the
signature of the Debtor where permitted by law, which financing statements may (but need not)
describe the Collateral as “all assets” or “all personal property” or words of like import, and
ratifies all such actions taken by the Collateral Agent. This power of attorney is coupled with an
interest and shall be irrevocable for the term of this Agreement and thereafter as long as any of
the Obligations shall be outstanding.

16. Notices. Any demand upon or notice to the Debtor hereunder shall be effective
when (i) delivered personally by hand or a nationally-recognized overnight courier; (ii) mailed by
registered or certified mail (postage prepaid), return receipt requested; (iii) sent via facsimile;
or (iv) sent via email delivery of a “.pdf” format data file to the appropriate party, in each case

the Collateral Agent in writing. Any notice by the Debtor to the Collateral Agent shall be given
as aforesaid, addressed to the Collateral Agent at the address shown below or such other address as
the Collateral Agent may advise the Debtor in writing. All such notices and other written
communication will be effective: (x) if delivered personally or mailed, upon delivery; and (y) if
sent via facsimile or via email delivery of “.pdf” format data file, upon confirmation of receipt.

17. Other Security. To the extent that the Obligations are now or hereafter secured
by property other than the Collateral or by the guarantee, endorsement or property of any other
person, firm, corporation or other entity, then the Collateral Agent shall have the right, in its
sole discretion, to pursue, relinquish, subordinate, modify or take any other action with respect
thereto, without in any way modifying or affecting any of the Collateral Agent’s rights and
remedies hereunder.

18. Miscellaneous.

(a) No course of dealing between the Debtor and the Collateral Agent, nor any
failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, any right,
power or privilege hereunder or under the Notes shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder or thereunder preclude any
other or further exercise thereof or the exercise of any other right, power or privilege.

(b) All of the rights and remedies of the Collateral Agent with respect to the
Collateral, whether established hereby or by the Notes, the Transaction Documents or by any other
agreements, instruments or documents or by law shall be cumulative and may be exercised singly or
concurrently.

(c) This Agreement, together with the exhibits and schedules hereto, the Notes and
the related agreements contemplated hereby and thereby contain the entire understanding of the
parties with respect to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties acknowledge have
been merged into this Agreement and the exhibits and schedules hereto. No provision of this
Agreement may be waived, modified, supplemented or amended except in a written instrument signed,
in the case of an amendment, by the Debtor and the Collateral Agent or, in the case of a waiver, by
the party against whom enforcement of any such waived provision is sought.

(d) If any term, provision, covenant or restriction of this Agreement is held by a
court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use
their commercially reasonable efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision, covenant or
restriction. It is hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions without including
any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(e) No waiver of any default with respect to any provision, condition or requirement
of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any
subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall
any delay or omission of any party to exercise any right hereunder in any manner impair the
exercise of any such right.

(f) This Agreement shall be binding upon and inure to the benefit of the parties and
their successors and permitted assigns. The Debtor and the Guarantors may not assign this
Agreement or any rights or obligations hereunder without the prior written consent of the
Collateral Agent (other than by merger). The Collateral Agent may assign any or all of its rights
under this Agreement to any Person to whom the Collateral Agent assigns or transfers any
Securities, provided such transferee agrees in writing to be bound, with respect to the transferred
Securities, by the provisions of this Agreement that apply to the “Collateral Agent.”

(g) Each party shall take such further action and execute and deliver such further
documents as may be necessary or appropriate in order to carry out the provisions and purposes of
this Agreement.

(h) All questions concerning the construction, validity, enforcement and
interpretation of this Agreement shall be governed by and construed and enforced in accordance with
the internal laws of the State of Delaware, without regard to the principles of conflicts of law
thereof. The Debtor agrees that all proceedings concerning the interpretations, enforcement and
defense of the transactions contemplated by this Agreement, the Transaction Documents and the Notes
(whether brought against a party hereto or its respective affiliates, directors, officers,
shareholders, partners, members, employees or agents) shall be commenced exclusively in the state
and federal courts sitting in the State of Delaware. The Debtor hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in the State of Delaware for the
adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in
any proceeding, any claim that it is not personally subject to the jurisdiction of any such court
or that such proceeding is improper. Each party hereto hereby irrevocably waives personal service
of process and consents to process being served in any such proceeding by mailing a copy thereof
via registered or certified mail or overnight delivery (with evidence of delivery) to such party at
the address in effect for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner permitted by law.
Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any
and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement
or the transactions contemplated hereby. If any party shall commence a proceeding to enforce any
provisions of this Agreement, then the prevailing party in such proceeding shall be reimbursed by
the other party for its reasonable attorney’s fees and other reasonable costs and expenses incurred
with the investigation, preparation and prosecution of such proceeding.

(i) This Agreement may be executed in any number of counterparts, each of which when
so executed shall be deemed to be an original and all of which taken together shall constitute one
and the same Agreement. In the event that any signature is delivered by facsimile transmission,
such signature shall create a valid binding obligation of the party executing (or on whose behalf
such signature is executed) the same with the same force and effect as if such facsimile signature
were the original thereof.

(j) The Debtor shall indemnify, reimburse and hold harmless the Collateral Agent and
each Investor, and each of their respective partners, members, shareholders, officers, directors,
employees and agents (and any other persons with other titles that have similar functions)
(collectively, “Indemnitees”) from and against any and all losses, claims, liabilities, damages,
penalties, suits, costs and expenses, of any kind or nature, (including fees relating to the cost
of investigating and defending any of the foregoing) imposed on, incurred by or asserted against
such Indemnitee in any way related to or arising from or alleged to arise from this Agreement or
the Collateral, except any such losses, claims, liabilities, damages, penalties, suits, costs and
expenses which result from the gross negligence or willful misconduct of the Indemnitee as
determined by a final, nonappealable decision of a court of competent jurisdiction. This
indemnification provision is in addition to, and not in limitation of, any other indemnification
provision in the Notes, the Transaction Documents or any other agreement, instrument or other
document executed or delivered in connection herewith or therewith.

(k) Nothing in this Agreement shall be construed to subject the Collateral Agent to
liability as a partner in the Debtor or any of its direct or indirect subsidiaries that is a
partnership or as a member in the Debtor or any of its direct or indirect subsidiaries that is a
limited liability company, nor shall the Collateral Agent be deemed to have assumed any obligations
under any partnership agreement or limited liability company agreement, as applicable, of the
Debtor or any of its direct or indirect subsidiaries or otherwise, unless and until the Collateral
Agent exercises its right to be substituted for the Debtor as a partner or member, as applicable,
pursuant hereto.

(l) To the extent that the grant of the security interest in the Collateral and the
enforcement of the terms hereof require the consent, approval or action of any partner or member,
as applicable, of the Debtor or any direct or indirect subsidiary of the Debtor or compliance with
any provisions of any of the Organizational Documents, the Debtor hereby grants such consent and
approval and waives any such noncompliance with the terms of said documents.

(m) The Investors have, pursuant to the Purchase Agreement appointed the Agent, as
their agent for purposes of exercising any and all rights and remedies of the secured parties
hereunder. Such appointment shall continue until revoked in writing (with a copy delivered to the
Debtor) in accordance with the Purchase Agreement.

which are hereby acknowledged), the Debtor and the Collateral Agent, for the benefit of the
Investors, agree as follows:

Investors, a security interest (having priority over all other security interests) with power of
sale, to the extent permitted by law, in all of its now owned or existing, and hereafter acquired
or arising:

	 	(a)	 	patents and patent applications, including, without limitation, any

the world (all of the foregoing registered trademarks, trademark applications,
trade names, trade styles, registered service marks and service mark
applications, together with the items described in clauses (i)-(iv) in this

referred to as the “Trademarks”);

	 	(c)	 	the goodwill of Debtor’s business connected with and symbolized by the
Trademarks; and

	 	(d)	 	copyrights, and copyright applications, including without limitation,
those copyrights listed in Schedule C (being sometimes referred to individually
and/or collectively as the “Copyrights”);

together with all additions, accessions, accessories, amendments, attachments, modifications,
substitutions, and replacements, proceeds and products of the foregoing.

2. Recording of Patents and Trademarks. Debtor represents and warrants that
(1) the patents and patent applications listed in Schedule A, and (2) the registered trademark and
trademark applications described in Schedule B, have each been duly recorded in the U.S. Patent and
Trademark Office (the “PTO”); and that no other patents, patent applications, trademarks,
or trademark applications have been filed or recorded with the PTO in which the Debtor has an
interest.

3. Recording of Copyrights. Debtor represents and warrants that the
registered copyrights and copyright applications described in Schedule C have been duly recorded in
the U.S. Copyright Office, and that no other copyrights or copyright applications have been
recorded in the U.S. Copyright Office, in which the Debtor has an interest.

4. Restrictions on Future Agreements. Debtor will not, without the
Collateral Agent’s prior written consent, enter into any agreement, including, without limitation,
any license agreement, that is inconsistent with this Agreement, and Debtor further agrees that it
will not take any action, and will use reasonable efforts not to knowingly permit any action to be
taken by others subject to its control, including licensees, or knowingly fail to take any action,
which would affect the validity or enforcement of the rights transferred to the Collateral Agent,
for the benefit of the Investors, under this Agreement or the rights associated with those Patents,
Trademarks and/or Copyrights which are in Debtor’s reasonable business judgment, necessary or
desirable in the operation of Debtor’s business.

5. New Patents, Trademarks and Copyrights. Debtor represents and warrants
that the Patents, Trademarks, and Copyrights listed on Schedules A, B, and C, include all of the
patents, patent applications, trademark registrations, trademark applications, service marks
registrations, service mark applications, registered copyrights and copyright applications, now
owned or held by Debtor. If, prior to the termination of this Agreement, Debtor shall (i) create
or obtain rights to any new patents, patent applications, trademarks, trademark registrations,
trademark applications, trade names, trade styles, service marks, service marks registrations, or
service mark applications, or (ii) become entitled to the benefit of any patent, patent
application, trademark, trademark registration, trademark application, trade name, trade style,
service mark, service mark registration, service mark application, the provisions of Section 1
above shall automatically apply thereto and Debtor shall give the Collateral Agent prompt written
notice thereof. Debtor hereby authorizes the Collateral Agent to modify this Agreement by (a)
amending Schedules A, B, and/or C, as the case may be, to include any future patents, patent
applications, trademark registrations, trademark applications, service mark registrations, service
mark applications, registered copyrights and copyright applications (whether or not any such notice
from Debtor has been sent or received), and (b) filing, in addition to and not in substitution for
this Agreement, a supplement or addendum to this Agreement containing the changes in the
information set forth on Schedule A, B and/or C therein, as the case may be, and to take any action
the Collateral Agent otherwise deems appropriate to perfect or maintain the rights and interest of
the Collateral Agent, for the benefit of the Investor, under this Agreement.

6. Nature and Continuation of Security Interest; Notice to Third Parties.
This Agreement has the effect of giving third parties notice of the Collateral Agent’s Security
Interest in Debtor’s Patents, Trademarks and Copyrights. This Agreement is made for collateral
security purposes only. This Agreement shall create a continuing security interest in the Patents,
Trademarks and Copyrights and shall remain in full force and effect until the Obligations have been
paid and satisfied in full, including all obligations under the Purchase Agreement and the other
Transaction Documents (as defined in the Purchase Agreement).

7. Right to Inspect; Assignments and Security Interests. The Collateral
Agent shall have the right, at any reasonable time upon prior written request and from time to
time, to inspect Debtor’s premises and to examine Debtor’s books, records and operations relating
to the Patents and the Trademarks, including, without limitation, Debtor’s quality control
processes; provided, that in conducting such inspections and examinations, the Collateral Agent
shall use reasonable efforts not to disturb unnecessarily the conduct of Debtor’s ordinary business
operations. From and after the occurrence of an event of default, under the Purchase Agreement, or
any other Transaction Documents (“Event of Default”), Debtor agrees that the Collateral Agent, or a
conservator appointed by the Collateral Agent, shall have the right to take any action to renew or
to apply for registration of any Patents, Trademarks and Copyrights as the Collateral Agent or said
conservator, on its sole judgment, may deem necessary or desirable in connection with the
enforcement of the Collateral Agent’s rights hereunder. Debtor agrees (i) except in accordance
with Debtor’s reasonable business judgment, not to sell or assign its respective interests in the
Patents, Trademarks and/or Copyrights without the prior written consent of the Collateral Agent and
(ii) to maintain the quality of any and all products in connection with which the Patents,
Trademarks and/or Copyrights are used, consistent with the quality of said products as of the date
hereof.

8. Duties of Debtor. The Debtor shall have the duty to (i) prosecute
diligently any patent application, trademark application or service mark application that is part
of the Collateral pending as of the date hereof or thereafter until the termination of this
Agreement, and (ii) preserve and maintain all of Debtor’s rights in the patents, patent
applications, trademark applications, service mark applications and trademark and service mark
registrations that are part of the Collateral. Any expenses incurred in connection with the
foregoing shall be borne by Debtor. Debtor shall not, without thirty (30) days prior written
notice to the Collateral Agent, abandon any Patent, Trademark or Copyright. The Collateral Agent
shall not have any duty with respect to the Patents, Trademarks or Copyrights. Without limiting
the generality of the foregoing, the Collateral Agent shall not be under any obligation to take any
steps necessary to preserve rights in the Patents, Trademarks or Copyrights against any other
parties, but may do so at its option during the continuance of an Event of Default, and all
expenses incurred in connection therewith shall be for the sole account of the Debtor and added to
the Obligations secured hereby and by the Security Agreement.

9. Collateral Agent’s Right to Sue. Upon the occurrence and during the
continuance of any Event of Default, the Collateral Agent shall have the right, for the benefit of
the Investors, to exercise all rights and remedies available at law or in equity. From and after
the occurrence and during the continuance of an Event of Default, the Collateral Agent shall have
the right, but shall not be obligated, to bring suit or take any other action to enforce the
Patents, Trademarks and Copyrights and, if the Collateral Agent shall commence any such suit or
take any such action, the Debtor shall, at the request of the Collateral Agent, do any and all
reasonable lawful acts and execute any and all proper documents reasonably required by the
Collateral Agent in aid of such enforcement. The Debtor shall, upon demand, promptly reimburse and
indemnify the Collateral Agent for all reasonable out-of-pocket costs and expenses incurred by the
Collateral Agent in the exercise of its rights under this Section 9 (including, without limitation,
all attorneys’ fees). If, for any reason whatsoever, the Collateral Agent is not reimbursed with
respect to the costs and expenses referred to in the preceding sentence, such costs and expenses
shall be added to the Obligations secured hereby.

10. Waivers. The Debtor waives to the extent permitted by applicable law
presentment, demand, notice, protest, notice of acceptance of this Agreement, notice of any loans
made, credit or other extensions granted, collateral received or delivered or any other action
taken in reliance hereon and all other demands and notices of any description, except for such
demands and notices as are expressly required to be provided to the Debtor under this Agreement or
any other Transaction Document. With respect to both the Obligations and the Collateral, the
Debtor assents to any extension or postponement of the time of payment or any other forgiveness or
indulgence, to any substitution, exchange or release of Collateral, to the addition or release of
any party or person primarily or secondarily liable, to the acceptance of partial payment thereon
and the settlement, compromise or adjustment of any thereof, all in such manner and at such time or
times as the Collateral Agent may deem advisable. The Collateral Agent may exercise its rights
with respect to the Collateral without resorting, or regard, to other collateral or sources of
reimbursement for Obligations. The Collateral Agent shall not be deemed to have waived any of its
rights with respect to the Obligations or the Collateral unless such waiver is in writing and
signed by the Collateral Agent. No delay or omission on the part of the Collateral Agent in
exercising any right shall operate as a waiver of such right or any other right. A waiver on any
one occasion shall not bar or waive the exercise of any right on any future occasion. All rights
and remedies of the Collateral Agent in the Obligations or the Collateral, whether evidenced hereby
or by any other instrument or papers, are cumulative and not exclusive of any remedies provided by
law or any other agreement, and may be exercised separately or concurrently.

11. Successors and Assigns. This Agreement shall be binding upon the
Debtor, its respective successors and permitted assigns, and shall inure to the benefit of and be
enforceable by the Collateral Agent and its successors and assigns. Without limiting the
generality of the foregoing sentence, the Collateral Agent may assign or otherwise transfer any
agreement or any note held by it evidencing, securing or otherwise executed in connection with the
Obligations, or sell participations in any interest therein, to any other person or entity.

12. General; Term.

	 	(a)	 	This Agreement may not be amended or modified except by a writing
signed by the Debtor and the Collateral Agent, nor may the Debtor assign any of
its rights hereunder. This Agreement and the terms, covenants and conditions
hereof shall be construed in accordance with, and governed by, the laws of the
State of Delaware (without giving effect to any conflicts of law provisions
contained therein). In the event that any Collateral stands in the name of the
Debtor and another or others jointly, as between the Collateral Agent and the
Debtor, the Collateral Agent may deal with the same for all purposes as if it
belonged to or stood in the name of the Debtor alone.

	 	(b)	 	This Agreement and the security interests granted herein shall
terminate on the date on which all payments under the Notes (as defined in the
Purchase Agreement) have been indefeasibly paid or satisfied in full (including
as a result of the conversion in full of the Notes) and all other Obligations
have been paid or discharged (other than contingent indemnification
obligations).

13. WAIVER OF JURY TRIAL; VENUE.

THE BORROWER HEREBY WAIVES TRIAL BY JURY IN ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN
CONNECTION WITH OR, ARISING OUT OF: (A) THIS AGREEMENT OR ANY OTHER INSTRUMENT OR DOCUMENT
DELIVERED IN CONNECTION HEREWITH; (B) THE VALIDITY, INTERPRETATION, COLLECTION OR ENFORCEMENT
THEREOF; OR (C) ANY OTHER CLAIM OR DISPUTE HOWEVER ARISING BETWEEN THE BORROWER AND THE LENDERS OR
THE AGENT IN RESPECT OF THIS AGREEMENT.

DELAWARE AND CONSENTS TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS AND TO SERVICE OF PROCESS IN
ANY SUCH SUIT BEING MADE UPON THE BORROWER BY MAIL AT THE ADDRESS SPECIFIED IN THE PURCHASE
AGREEMENT. THE BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE

BORROWER SHALL NOT BE ENTITLED IN ANY SUCH ACTION OR PROCEEDING TO ASSERT ANY DEFENSE GIVEN OR
ALLOWED UNDER THE LAWS OF ANY STATE OTHER THAN THE STATE OF DELAWARE UNLESS SUCH DEFENSE IS ALSO
GIVEN OR ALLOWED BY THE LAWS OF THE STATE OF DELAWARE. NOTHING IN THIS SECTION SHALL AFFECT OR
IMPAIR IN ANY MANNER OR TO ANY EXTENT THE RIGHT OF THE AGENT TO COMMENCE LEGAL PROCEEDINGS OR
OTHERWISE PROCEED AGAINST THE BORROWER IN ANY JURISDICTION IN WHICH ANY COLLATERAL IS LOCATED, THE
BORROWER CONDUCTS ACTIVITIES OR WHERE LEGAL PROCEEDINGS MAY BE NECESSARY IN ORDER TO COLLECT OR
