however, that the failure of Borrowers to comply with Section 13c of this Agreement prior
to the date of the First Amendment to Forbearance Agreement shall not constitute an Event of

     2. Except as herein amended, all terms and conditions of the Forbearance Agreement are hereby
reaffirmed and shall remain in full force and effect as originally written and shall be construed
as one document with this Amendment.

     3. Ratification of Existing Agreements and Amounts Owing. Borrowers hereby reaffirm
all of the terms, conditions, representations and warranties of each of the Documents and the

this Amendment, ratified and confirmed in all respects by Borrowers. Borrowers acknowledge that,

Lien on the Collateral, whether now owned or hereafter acquired, created or arising, as set forth

priority lien status in the Collateral.

     4. Representations and Warranties. Borrowers hereby represent and warrant that: (a)
Borrowers are duly formed, validly existing and in legal good standing in the State of Delaware,
that each of Borrowers has the power and authority to enter into this Amendment; (b) Borrowers have
duly executed and delivered this Amendment and this Amendment constitutes the valid, binding and
legal obligation of Borrowers; (c) this Amendment is not being entered into with the intent to
hinder or defraud any person; and (d) the recitals set forth in the Recitals of this Amendment and
all information and documents provided to Lenders in connection herewith are true, accurate and
complete in all material respects. Further, Borrowers confirm, reaffirm and restate in all material
respects to the Lenders, on and as of the date of this Amendment first indicated above, the
representations and warranties set forth in the Loan Agreement, the Credit Agreement, the Former
Forbearance Agreement, the Forbearance Agreement and the other Documents, except as may be set
forth herein or to the extent that such representations and warranties solely relate to a specific
earlier date in which case Borrowers confirm, reaffirm and restate in all material respects such
representations and warranties as of such earlier date. Each request for an Advance under the
Revolving Facility shall constitute Borrowers’ confirmation, reaffirmation and restatement in all
material respects of the representations and warranties set forth in this Amendment, the Loan
Agreement, the Credit Agreement, the Former Forbearance Agreement, the Forbearance Agreement and
the other Documents as of the date of each such request, except as set forth herein or except to
the extent that such representations and warranties relate to a specific earlier date in which case
each such request shall constitute Borrowers’

2

 

confirmation, reaffirmation and restatement in all material respects of such representations
and warranties as of such earlier date.

     5. Release of Lenders. By execution of this Amendment, Borrowers acknowledge and
confirm that they do not have any offsets, defenses or claims whatsoever against Agents, Lenders,
or any of Agents or Lenders’ subsidiaries, affiliates, officers, directors, employees, agents,
consultants, attorneys, predecessors, successors or assigns whether asserted or unasserted as of
the date of this Amendment first indicated above. To the extent that such offsets, defenses or
claims may exist, Borrowers for each of themselves and their successors, assigns, parents,
subsidiaries, affiliates, predecessors, employees, agents, heirs and executors, as applicable
(collectively, “Releasors”), jointly and severally, knowingly, voluntarily and
intentionally release and forever discharge Agents, Lenders, their subsidiaries, affiliates,
officers, directors, employees, agents, consultants, attorneys, predecessors, successors and
assigns, both present and former (individually, a “Releasee” and collectively, the
“Releasees”) of and from any and all manner of actions, causes of action, suits, debts,
controversies, torts, damages, judgments, executions, claims and demands whatsoever, including,
without limitation, any so-called “lender liability” claims or defenses which it has, asserted or
unasserted, in law or in equity, which Releasors ever had or now have against the Releasees,
including, without limitation, any presently existing claim or defense whether or not presently
suspected, contemplated or anticipated based upon, or in any manner connected with (i) any
transaction, event circumstance, action, omission, failure to act or occurrence of any sort or
type, whether known or unknown, which occurred, existed, or was taken or permitted prior to the
execution of this Amendment with respect to the Obligations, the Documents, including the Former
Forbearance Agreement and the Forbearance Agreement, or the administration thereof (ii) any
discussions, commitments, negotiations, conversations or communications, whether oral or evidenced
by a writing of any sort prior to the execution of this Amendment with respect to the Obligations,
or (iii) any thing or matter related to any of the foregoing prior to the execution of this
Amendment. Borrowers acknowledge and agree that the inclusion of this paragraph in this Amendment
and the execution of this Amendment by the Agents and Lenders does not constitute an acknowledgment
or admission by the Agents or Lenders of liability for any matter, or a precedent upon which any
liability may be asserted. If Borrowers assert or commence any claim, counter-claim, demand,
obligation, liability or cause of action in derogation of the foregoing release or challenges the
enforceability of the foregoing release (in each case, a “Violation”), then the Borrowers
jointly and severally agree to pay in addition to such other damages as any Releasee may sustain as
a result of such Violation, all attorneys’ fees and expenses (including in-house and outside
counsels’) incurred by such Releasee as a result of such Violation.

     6. This Amendment may be executed in counterparts, each of which will be deemed an original
document, but all of which will constitute a single document. Facsimile and pdf versions of
signatures hereto shall be deemed original signatures, which may be relied upon by all Parties
hereby and shall be binding on the respective signor.

	 	November 28, 2006

THIS AMENDED AND RESTATED SENIOR SECURED CONVERTIBLE NOTE (this “Note”) executed by Zila,
Inc., a Delaware corporation (“Company”), amends, restates and replaces that certain 6%
Senior Secured Convertible Note, dated as of November 28, 2006 (the “Original Note”), in
the principal amount of                     , executed by Company in favor of
                                        
(the “Holder”). This Note and the Original Note constitute a
single, ongoing obligation of the Company.

     FOR VALUE RECEIVED, the Company hereby unconditionally promises to pay to the order of the
Holder, having an address at                     , at such address or at such other place as
may be designated in writing by the Holder, or its assigns, the aggregate principal sum of                     
Million United States Dollars ($                    ), together with interest from July 29, 2007 on the
unpaid principal balance of this Note outstanding at a rate equal to seven percent (7%) per annum
(computed on the basis of the actual number of days elapsed in a 360-day year) and continuing on
the outstanding principal until this Note is converted into Common Stock as provided herein or
indefeasibly and irrevocably paid in full by the Company. Notwithstanding the preceding sentence,
the Company shall have the right, at its option, to pay interest at a rate equal to eight percent
(8%) per annum (computed on the basis of the actual number of days elapsed in a 360-day year) in
the form of duly authorized, fully paid and nonassessable shares of Common Stock (the “PIK
Shares”). Each PIK Share shall have a value equal to 90% of the average closing bid price per
share of the Common Stock for the ten (10) Trading Days immediately prior to the relevant Interest
Payment Date. Interest on this Note shall accrue and shall be payable quarterly on each January
31, April 30, July 31, and October 31 for the preceding quarter (each, an “Interest Payment
Date”), commencing on October 31, 2007. Subject to the other provisions of this Note, the
principal of this Note and all accrued and unpaid interest hereon shall mature and become due and
payable on July 31, 2010 (the “Stated Maturity Date”). Except as provided herein, all
payments of principal and interest by the Company under this Note shall be made in United States
dollars in immediately available funds to an account specified by the Holder. In no event shall
any interest charged, collected or reserved under this Note exceed the maximum rate then permitted
by applicable law and if any such payment is paid

 

 

by the Company, then such excess sum shall be credited by the Holder as a payment of
principal.

          Upon the occurrence and during the continuation of any Event of Default hereunder, all amounts
outstanding hereunder shall bear interest at an annual rate of fifteen percent (15%). For purposes
of any of the covenants set forth in Sections 5(a)(xiii) and 5(a)(xiv) only, any Event of Default
caused by a breach of any such covenant shall be cured and shall no longer continue upon the
satisfaction by the Company of such covenant for the next succeeding quarter, to the extent
applicable. In no event shall any interest charged, collected or reserved under this Note exceed
the maximum rate then permitted by applicable law and if any such payment is paid by the Company,
then such excess sum shall be credited by the Holder as a payment of principal.

          This Note is one of a series of Notes (the “Company Notes”) of like tenor in an

8

 

     3. Prepayment. This Note shall not be prepayable or redeemable by the Company prior

     4. Conversion.

          (a) The Holder shall have the right, at its option, exercisable at any time, effective upon
delivery to the Company of a Conversion Notice, to convert all or a portion of the principal amount
of this Note and any accrued and unpaid interest due on the portion of the principal amount of this
Note being converted into fully paid and nonassessable shares of the Common Stock at the Conversion
Price then in effect. The date of any optional conversion is hereinafter referred to as the
“Optional Conversion Date.”

          (b) [reserved]

          (c) Promptly after any Optional Conversion Date, the Holder of this Note shall deliver this
Note to the Company (or, in lieu thereof, an appropriate lost security affidavit in the event this
Note shall have been lost or destroyed, together with a customary indemnity agreement) to the
Company at its principal office (or such other office or agency of the Company as the Company may
designate by notice in writing to the Holder), together with a statement of the name or names (with
address) in which the certificate or certificates for the Conversion Shares issuable upon such
conversion shall be issued. Promptly following the surrender of this Note (or, in lieu thereof,
delivery of an appropriate lost security affidavit in the event this Note shall have been lost or
destroyed, together with a customary indemnity agreement) as aforesaid, but in no event more than
three (3) Business Days thereafter, the Company shall issue and deliver, or cause to be issued and
delivered, to the Holder, registered in such name or names as the Holder may direct in writing, a
certificate or certificates for the number of whole Conversion Shares issuable upon the conversion
of this Note and, in the case of the conversion of less than the entire amount of this Note, a new
note of like tenor in the principal amount of this Note not being converted on the relevant
Optional Conversion Date. To the extent permitted by law, such conversion shall be deemed to have
been effected, and the Conversion Price shall be determined, as of the close of business on the
Optional Conversion Date and at such time, the rights of the Holder shall cease with respect to the
Note, or amount thereof, being converted, and the Person or Persons in whose name or names any
certificate or certificates for Conversion Shares shall be issuable upon such conversion shall be
deemed to have become the holder or holders of record of the Conversion Shares represented thereby.

          (d) No fractional shares shall be issued upon any conversion of this Note into Common Stock.
If any fractional share of Common Stock would, except for the provisions of the first sentence of
this Section 4(d), be delivered upon such conversion, the Company, in lieu of delivering such
fractional share, shall pay to the Holder an amount in cash equal to the Market Price of such
fractional share of Common Stock.

          (e) If the Company shall, at any time or from time to time while this Note is outstanding, pay
a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its
outstanding shares of Common Stock into a greater number of shares or combine its outstanding
shares of Common Stock into a smaller number of shares or issue by reclassification of its
outstanding shares of Common Stock any shares of its capital stock

9

 

(including any such reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation), then (i) the Conversion Price in effect immediately prior
to the date on which such change shall become effective shall be adjusted by multiplying such
Conversion Price by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such change and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after giving effect to such change and (ii) the
number of Conversion Shares issuable upon conversion of this Note shall be adjusted by multiplying
the number of Conversion Shares issuable upon conversion of this Note immediately prior to the date
on which such change shall become effective by a fraction, the numerator of which is shall be the
Conversion Price in effect immediately prior to the date on which such change shall become
effective and the denominator of which shall be the Conversion Price in effect immediately after
giving effect to such change, calculated in accordance with clause (i) above. Such adjustments
shall be made successively whenever any event listed above shall occur.

          (f) If any capital reorganization, reclassification of the capital stock of the Company,
consolidation or merger of the Company with another corporation in which the Company is not the
survivor, or sale, transfer or other disposition of all or substantially all of the Company’s
assets to another Person shall be effected, then, as a condition of such reorganization,
reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate
provision shall be made whereby the Holder shall thereafter have the right, at its option, either
(i) to purchase and receive upon the basis and upon the terms and conditions herein specified and
in lieu of the Conversion Shares immediately theretofore issuable upon conversion of this Note such
shares of stock, securities or assets as would have been issuable or payable with respect to or in
exchange for a number of Conversion Shares equal to the number of Conversion Shares immediately
theretofore issuable upon conversion of this Note, had such reorganization, reclassification,
consolidation, merger, sale, transfer or other disposition not taken place, and in any such case
appropriate provision shall be made with respect to the rights and interests of the Holder to the
end that the provisions hereof (including, without limitation, provision for adjustment of the
Conversion Price) shall thereafter be applicable, as nearly equivalent as may be practicable in
relation to any shares of stock, securities or assets thereafter deliverable upon the conversion
hereof or (ii) in the event or any such consolidation or merger of the Company or such sale,
transfer or other disposition of all or substantially all of the Company’s assets only, to cause
the Company to redeem this Note at a redemption price equal to 110% of the outstanding principal
amount of this Note, together with all accrued and unpaid interest hereon to the date of
redemption, which right must be exercised by the Holder within ten (10) Business Days after receipt
by it from the Company of written notice of the occurrence of any transaction giving rise to such
right. The Company shall not effect any such consolidation, merger, sale, transfer or other
disposition unless prior to or simultaneously with the consummation thereof the successor
corporation (if other than the Company) resulting from such consolidation or merger, or the
corporation purchasing or otherwise acquiring such assets or other appropriate corporation or
entity shall assume the obligation to deliver to the Holder, at the last address of the Holder
appearing on the books of the Company, such shares of stock, securities or assets as, in accordance
with the foregoing provisions, the Holder may be entitled to purchase, without regard to any
conversion limitation specified in Section 4, and the other obligations under this Note. The
provisions of this paragraph (f) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales, transfers or other dispositions.

10

 

          (g) In case the Company shall fix a payment date for the making of a distribution to all
holders of Common Stock (including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing corporation) of evidences of indebtedness or assets
(other than cash dividends or cash distributions payable out of consolidated earnings or earned
surplus or dividends or distributions referred to in Section 4(e)), or subscription rights or
warrants, the Conversion Price to be in effect after such payment date shall be determined by
multiplying the Conversion Price in effect immediately prior to such payment date by a fraction,
the numerator of which shall be the total number of shares of Common Stock outstanding multiplied
by the Market Price of Common Stock immediately prior to such payment date, less the fair market
value (as determined by the Board in good faith) of said assets or evidences of indebtedness so
distributed, or of such subscription rights or warrants, and the denominator of which shall be the
total number of shares of Common Stock outstanding multiplied by such Market Price immediately
prior to such payment date. Such adjustment shall be made successively whenever such a payment
date is fixed.

          (h) An adjustment to the Conversion Price shall become effective immediately after the payment
date in the case of each dividend or distribution and immediately after the effective date of each
other event which requires an adjustment.

          (i) In the event that, as a result of an adjustment made pursuant to this Section 4, the
Holder shall become entitled to receive any shares of capital stock of the Company other than
shares of Common Stock, the number of such other shares so receivable upon conversion of this Note
shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions contained in this Note.

          (j) Except as provided in Section 4(j) hereof, if and whenever the Company shall issue or
sell, or is, in accordance with any of Sections 4(j)(i) through 4(j)(vii) hereof, deemed to have
issued or sold, any Additional Shares of Common Stock (as defined below) for no consideration or
for a consideration per share less than the Conversion Price in effect immediately prior to the
time of such issuance or sale, then and in each such case (a “Trigger Issuance”) the
then-existing Conversion Price, shall be reduced, as of the close of business on the effective date
of the Trigger Issuance, to a price determined as follows:

          Adjusted Conversion Price = (A x B) + D

                                                              A+C

                    where

                    “A” equals the number of shares of Common Stock outstanding, including Additional Shares of
Common Stock (as defined below) deemed to be issued hereunder, immediately preceding such Trigger
Issuance;

                    “B” equals the Conversion Price in effect immediately preceding such Trigger Issuance;

                    “C” equals the number of Additional Shares of Common Stock issued or deemed issued hereunder
as a result of the Trigger Issuance; and

11

 

                    “D” equals the aggregate consideration, if any, received or deemed to be received by the
Company upon such Trigger Issuance;

provided, however, that in no event shall the Conversion Price after giving effect to such Trigger
Issuance be greater than the Conversion Price in effect prior to such Trigger Issuance.

          For purposes of this subsection (j), “Additional Shares of Common Stock” shall mean
all shares of Common Stock issued or sold by the Company or deemed to be issued or sold pursuant to
this subsection (j), other than Excluded Issuances (as defined in subsection (k) hereof).

          For purposes of this Section 4(j), the following subsections (j)(i) to (j)(viii) shall also be
applicable (subject, in each such case, to the provisions of Section 4(k) hereof):

          (i) In case at any time the Company shall in any manner grant (directly and not by assumption
in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any
options for the purchase of, Common Stock or any stock or security convertible into or exchangeable
for Common Stock (such warrants, rights or options being called “Options” and such
convertible or exchangeable stock or securities being called “Convertible Securities”)
whether or not such Options or the right to convert or exchange any such Convertible Securities are
immediately exercisable, and the price per share for which Common Stock is issuable upon the
exercise of such Options or upon the conversion or exchange of such Convertible Securities
(determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of
(x) the total amount, if any, received or receivable by the Company as consideration for the
granting of such Options, plus (y) the aggregate amount of additional consideration payable to the
Company upon the exercise of all such Options, plus (z), in the case of such Options which relate
to Convertible Securities, the aggregate amount of additional consideration, if any, payable upon
the issuance or sale of such Convertible Securities and upon the conversion or exchange thereof, by
(ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options
or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of
such Options) shall be less than the Conversion Price immediately prior to the time of the granting
of such Options, then the total number of shares of Common Stock issuable upon the exercise of such
Options or upon conversion or exchange of the total amount of such Convertible Securities issuable
upon the exercise of such Options shall be deemed to have been issued for such price per share as
of the date of granting of such Options or the issuance of such Convertible Securities and
thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price.
Except as otherwise provided in subsection 4(i)(iii), no adjustment of the Conversion Price shall
be made upon the actual issuance of such Common Stock or of such Convertible Securities upon
exercise of such Options or upon the actual issuance of such Common Stock upon conversion or
exchange of such Convertible Securities.

          (ii) In case the Company shall in any manner issue (directly and not by assumption in a merger
or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert
any such Convertible Securities are immediately exercisable, and the price per share for which
Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the sum
(which sum shall constitute the applicable consideration) of (x) the total amount received or
receivable by the Company as consideration for the issuance or

12

 

sale of such Convertible Securities, plus (y) the aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the
total number of shares of Common Stock issuable upon the conversion or exchange of all such
Convertible Securities) shall be less than the Conversion Price immediately prior to the time of
such issuance or sale, then the total maximum number of shares of Common Stock issuable upon
conversion or exchange of all such Convertible Securities shall be deemed to have been issued for
such price per share as of the date of the issuance or sale of such Convertible Securities and
thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price,
provided that (a) except as otherwise provided in subsection 4(j)(iii), no adjustment of the
Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion or
exchange of such Convertible Securities and (b) no further adjustment of the Conversion Price shall
be made by reason of the issuance or sale of Convertible Securities upon exercise of any Options to
purchase any such Convertible Securities for which adjustments of the Conversion Price have been
made pursuant to the other provisions of Section 4(j).

          (iii) Upon the happening of any of the following events, namely, if the purchase price
provided for in any Option referred to in subsection 4(j)(i) hereof, the additional consideration,
if any, payable upon the conversion or exchange of any Convertible Securities referred to in
subsections 4(j)(i) or 4(j)(ii), or the rate at which Convertible Securities referred to in
subsections 4(j)(i) or 4(j)(ii) are convertible into or exchangeable for Common Stock shall change
at any time (including, but not limited to, changes under or by reason of provisions designed to
protect against dilution), the Conversion Price in effect at the time of such event shall forthwith
be readjusted to the Conversion Price which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase price, additional
consideration or conversion rate, as the case may be, at the time initially granted, issued or
sold. On the termination of any Option for which any adjustment was made pursuant to this
subsection 4(j) or any right to convert or exchange Convertible Securities for which any adjustment
was made pursuant to this subsection 4(j) (including without limitation upon the redemption or
purchase for consideration of such Convertible Securities by the Company), the Conversion Price
then in effect hereunder shall forthwith be changed to the Conversion Price which would have been
in effect at the time of such termination had such Option or Convertible Securities, to the extent
outstanding immediately prior to such termination, never been issued.

          (iv) Subject to the provisions of this Section 4(j), in case the Company shall declare a
dividend or make any other distribution upon any stock of the Company (other than the Common Stock)
payable in Common Stock, Options or Convertible Securities, then any Common Stock, Options or
Convertible Securities, as the case may be, issuable in payment of such dividend or distribution
shall be deemed to have been issued or sold without consideration; provided, that if any adjustment
is made to the Conversion Price as a result of a declaration of a dividend and such dividend is
rescinded, the Conversion Price shall be appropriately readjusted to the Conversion Price in effect
had such dividend not been declared.

          (v) In case any shares of Common Stock, Options or Convertible Securities shall be issued or
sold for cash, the consideration received therefor shall be deemed to be the net amount received by
the Company therefor, after deduction therefrom of any expenses incurred or any underwriting
commissions or concessions paid or allowed by the Company in connection

13

 

therewith. In case any shares of Common Stock, Options or Convertible Securities shall be
issued or sold for a consideration other than cash, the amount of the consideration other than cash
received by the Company shall be deemed to be the fair value of such consideration as determined in
good faith by the Board, after deduction of any expenses incurred or any underwriting commissions
or concessions paid or allowed by the Company in connection therewith. In case any Options shall
be issued in connection with the issuance and sale of other securities of the Company, together
comprising one integral transaction in which no specific consideration is allocated to such Options
by the parties thereto, such Options shall be deemed to have been issued for such consideration as
determined in good faith by the Board of Directors of the Company. If Common Stock, Options or
Convertible Securities shall be issued or sold by the Company and, in connection therewith, other
Options or Convertible Securities (the “Additional Rights”) are issued, then the
consideration received or deemed to be received by the Company shall be reduced by the fair market
value of the Additional Rights (as determined using the Black-Scholes option pricing model or
another method mutually agreed to by the Company and the Holder). The Board shall respond
promptly, in writing, to an inquiry by the Holder as to the fair market value of the Additional
Rights. In the event that the Board and the Holder are unable to agree upon the fair market value
of the Additional Rights, the Company and the Holder shall jointly select an appraiser, who is
experienced in such matters. The decision of such appraiser shall be final and conclusive, and the
cost of such appraiser shall be borne evenly by the Company and the Holder.

          (vi) In case the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock,
Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or
Convertible Securities, then such record date shall be deemed to be the date of the issuance or
sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

          (vii) The number of shares of Common Stock outstanding at any given time shall not include
shares owned or held by or for the account of the Company or any of its wholly-owned subsidiaries,
and the disposition of any such shares (other than the cancellation or retirement thereof) shall be
considered an issuance or sale of Common Stock for the purpose of this subsection (j).

          (viii) Notwithstanding any other provision in this subsection (j) to the contrary, if a
reduction in the Conversion Price pursuant to this subsection (j) (other than as set forth in this
clause (viii)) would require the Company to obtain stockholder approval of the transactions
contemplated by the Purchase Agreement to be consummated on the Closing Date pursuant to Nasdaq
Marketplace Rule 4350(i) and such stockholder approval has not been obtained, (i) the Conversion
Price shall be reduced to the maximum extent that would not require stockholder approval under such
Rule, and (ii) the Company shall use its commercially reasonable efforts to obtain such stockholder
approval as soon as reasonably practicable, including by calling a special meeting of stockholders
to vote on such Conversion Price adjustment. This provision shall not restrict the number of
shares of Common Stock which a Holder may receive or beneficially own in order to determine the
amount of securities or other consideration that such Holder may receive in the event of a
transaction contemplated by Section 4 of this Note.

14

 

          (k) Anything herein to the contrary notwithstanding, the Company shall not be required to make
any adjustment of the Conversion Price in the case of the issuance of (A) capital stock, Options or
Convertible Securities issued to directors, officers, employees or consultants of the Company in
connection with their service as directors of the Company, their employment by the Company or their
retention as consultants by the Company pursuant to an equity compensation program approved by the
Board of Directors of the Company or the compensation committee of the Board of Directors of the
Company, (B) shares of Common Stock issued upon the conversion or exercise of Options or
Convertible Securities issued prior to the date hereof, provided such securities are not amended
after the date hereof to increase the number of shares of Common Stock issuable thereunder or to
lower the exercise or conversion price thereof, (C) securities issued pursuant to the Purchase
Agreement and securities issued upon the exercise or conversion of those securities, (D) shares of
Common Stock issued or issuable by reason of a dividend, stock split or other distribution on
shares of Common Stock (but only to the extent that such a dividend, split or distribution results
in an adjustment in the Conversion Price pursuant to the other provisions of this Note) and (E) the
issuance of any PIK Shares (collectively, “Excluded Issuances”).

          (l) In case at any time:

          (i) the Company shall declare any dividend upon its Common Stock or any other class or series
of capital stock of the Company payable in cash or stock or make any other distribution to the
holders of its Common Stock or any such other class or series of capital stock;

          (ii) the Company shall offer for subscription pro rata to the holders of its
Common Stock or any other class or series of capital stock of the Company any additional shares of
stock of any class or other rights; or

          (iii) there shall be any capital reorganization or reclassification of the capital stock of
the Company, any acquisition or a liquidation, dissolution or winding up of the Company;

then, in any one or more of said cases, the Company shall give, by delivery in person or by
certified or registered mail, return receipt requested, addressed to the Holder at the address of
such Holder as shown on the books of the Company, (a) at least 20 Business Days’ prior written
notice of the date on which the books of the Company shall close or a record shall be taken for
such dividend, distribution or subscription rights or for determining rights to vote in respect of
any event set forth in clause (iii) of this Section 4(l) and (b) in the case of any event set forth
in clause (iii) of this Section 4(l), at least 20 Business Days’ prior written notice of the date
when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also
specify, in the case of any such dividend, distribution or subscription rights, the date on which
the holders of Common Stock or such other class or series of capital stock shall be entitled
thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on
which the holders of Common Stock and such other series or class of capital stock shall be entitled
to exchange their Common Stock and other stock for securities or other property deliverable upon
consummation of the applicable event set forth in clause (iii) of this Section 4(l).

15

 

          (m) Upon any adjustment of the Conversion Price, then and in each such case the Company shall
give prompt written notice thereof, by delivery in person or by certified or registered mail,
return receipt requested, addressed to the Holder at the address of such Holder as shown on the
books of the Company, which notice shall state the Conversion Price resulting from such adjustment
and setting forth in reasonable detail the method upon which such calculation is based.

          (n) The Company shall at all times reserve and keep available out of its authorized Common
Stock, solely for the purpose of issuance upon conversion of this Note as herein provided, such
number of shares of Common Stock as shall then be issuable upon the conversion of this Note. The
Company covenants that all shares of Common Stock which shall be so issued shall be duly and
validly issued and fully paid and nonassessable, and free from all taxes, liens and charges with
respect to the issue thereof, and, without limiting the generality of the foregoing, and that the
Company will from time to time take all such action as may be requisite to assure that the par
value per share of the Common Stock is at all times equal to or less than the Conversion Price in
effect at the time. The Company shall take all such action as may be necessary to assure that all
such shares of Common Stock may be so issued without violation of any applicable law or regulation,
or of any requirement of any national securities exchange or trading market upon which the Common
Stock may be listed. The Company shall not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and issuable after such
action upon conversion of this Note would exceed the total number of shares of Common Stock then
authorized by the Company’s Certificate of Incorporation.

          (o) The issuance of certificates for shares of Common Stock upon conversion of this Note shall
be made without charge to the holders thereof for any issuance tax in respect thereof, provided
that the Company shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issuance and delivery of any certificate in a name other than that of the
Holder. When the Company is required to issue Conversion Shares hereunder, if: (1) certificates
representing such Conversion Shares are not delivered to the Holder within three (3) Business Days
of the Optional Conversion Date, and (2) prior to the time such certificates are received, the
Holder, or any third party on behalf of such Holder or for the Holder’s account, purchases (in an
open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale
by the Holder of such certificates (a “Buy-In”), then the Company shall pay in cash to the
Holder (for costs incurred either directly by such Holder or on behalf of a third party) the amount
by which the total purchase price paid for Common Stock as a result of the Buy-In (including
brokerage commissions, if any) exceeds the proceeds received by the Holder as a result of the sale
to which such Buy-In relates. The Holder shall provide the Company written notice indicating the
amounts payable to the Holder in respect of the Buy-In.

          (p) The Company will not at any time close its transfer books against the transfer, as
applicable, of this Note or of any shares of Common Stock issued or issuable upon the conversion of
this Note in any manner which interferes with the timely conversion of this Note, except as may
otherwise be required to comply with applicable securities laws.

          (q) Notwithstanding anything to the contrary contained herein, the number of Conversion Shares
that may be acquired by the Holder upon any conversion of this Note (or

16

 

otherwise in respect hereof) shall be limited to the extent necessary to insure that,
following such conversion (or other issuance), the total number of shares of Common Stock then
beneficially owned by such Holder and its Affiliates and any other Persons whose beneficial
ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”), does not exceed
9.999% of the total number of issued and outstanding shares of Common Stock (including for such
purpose the shares of Common Stock issuable upon such conversion). For such purposes, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules
and regulations promulgated thereunder. This provision shall not restrict the number of shares of
Common Stock which a Holder may receive or beneficially own in order to determine the amount of
securities or other consideration that such Holder may receive in the event of a transaction
contemplated by Section 4(f) of this Note. This restriction may not be waived.

          (ix) The Company shall and shall cause each Subsidiary to comply with all laws, rules,

Office and any corresponding foreign patent and/or trademark office required for the Company or any

Company shall not and shall cause each Subsidiary not to transfer, assign or otherwise convey the
Intellectual Property, any registrations or applications thereof and all goodwill associated
therewith, to any person or entity.

          (b) So long as any amount due under this Note is outstanding and until the earlier of (i) the
indefeasible payment in full of all amounts payable by the Company hereunder and (ii) the
conversion of this Note, without the prior written consent of the Majority Holders (for purposes of
this Section 5(b), any Company Notes held by any employee, director or officer of the Company or
any Subsidiary shall not be deemed to be outstanding):

          (i) The Company shall not and shall cause each Subsidiary not to create, incur, guarantee,
issue, assume or in any manner become liable in respect of any Indebtedness, other than Permitted
Indebtedness.

          (ii) The Company shall not and shall cause each Subsidiary not to create, incur, assume or

ability of the Company or any Subsidiary to grant Liens.

19

 

          (iii) The Company shall not and shall cause each Subsidiary not to, directly or indirectly,
enter into or permit to exist any transaction or series of related transactions (including, without
limitation, the purchase, sale, lease or exchange of any property or the rendering of any service
(other than service as an employee)) with, or for the benefit of, any of its Affiliates other than
a wholly owned Subsidiary, except for consulting arrangements with directors approved by the Board.

          (iv) The Company shall not, and shall cause each of its Subsidiaries not to, directly or

     6. Event of Default. The occurrence of any of following events shall constitute an
“Event of Default” hereunder:

          (a) the failure of the Company to make any payment of principal on this Note when due, whether
at maturity, upon acceleration or otherwise;

          (b) the failure of the Company to make any payment of interest on this Note, or any other
amounts due under the other Transaction Documents (as defined under the Purchase Agreement) when
due, whether on an Interest Payment Date, at maturity, upon acceleration or otherwise, and such
failure continues for more than five (5) days;

          (c) the Company and/or its Subsidiaries fail to make a required payment or payments on
Indebtedness of $250,000 or more in aggregate principal amount and such failure continues for more
than ten (10) days;

          (d) there shall have occurred an acceleration of the stated maturity of any Indebtedness of
the Company or its Subsidiaries of $250,000 or more in aggregate principal amount (which
acceleration is not rescinded, annulled or otherwise cured within ten (10) days of receipt by the
Company or a Subsidiary of notice of such acceleration);

          (e) the Company makes an assignment for the benefit of creditors or admits in writing its
inability to pay its debts generally as they become due; or an order, judgment or decree is entered
adjudicating the Company as bankrupt or insolvent; or any order for relief with respect to the
Company is entered under title 11 of the United States Code or any other bankruptcy or insolvency
law; or the Company petitions or applies to any tribunal for the

21

 

appointment of a custodian, trustee, receiver or liquidator of the Company or of any
substantial part of the assets of the Company, or commences any proceeding relating to it under any
bankruptcy, reorganization, arrangement, insolvency, readjustment of debt, dissolution or
liquidation law of any jurisdiction; or any such petition or application is filed, or any such
proceeding is commenced, against the Company and either (i) the Company by any act indicates its
approval thereof, consents thereto or acquiescence therein or (ii) such petition application or
proceeding is not dismissed within sixty (60) days;

          (f) a final, non-appealable judgment which, in the aggregate with other outstanding final
judgments against the Company and its Subsidiaries, exceeds $250,000 shall be rendered against the
Company or a Subsidiary and within sixty (60) days after entry thereof, such judgment is not
discharged or execution thereof stayed pending appeal, or within sixty (60) days after the
expiration of such stay, such judgment is not discharged; provided, however, that a judgment that
provides for the payment of royalties subsequent to the date of the judgment shall be deemed to be
discharged so long as the Company or the Subsidiary affected thereby is in compliance with the
terms of such judgment;

          (g) the Company is in breach of the requirements of Sections 5(a)(xiii) or 5(a)(xiv) or
Section 5(b) hereof;

          (h) if any representation or statement of fact made in the Amendment Agreement, any
Transaction Document, certificate or other document furnished to the Holder at any time by or on
behalf of the Company proves to have been false in any material respect when made or furnished;

          (i) any Liens created by the Security Documents shall at any time not constitute a valid and
perfected first priority Lien on the collateral intended to be covered thereby (to the extent
perfection by filing, registration, recordation or possession is required herein or therein) in
favor of the Holders, free and clear of all other Liens (other than Permitted Liens), or any of the
security interests granted pursuant to the Security Documents shall be determined to be void,
voidable, invalid or unperfected, are subordinated or are ineffective to provide the Holder with a
perfected, first priority security interest in the collateral covered by the Security Documents,
free and clear of all other Liens (other than Permitted Liens) or, except for expiration or
termination in accordance with their terms, the Security Agreement shall for whatever reason be
terminated or cease to be in full force and effect, or the enforceability thereof or any other
Transaction Documents shall be contested by the Company; or

          (j) if the Company fails to observe or perform in any material respect any of its covenants
contained in the Transaction Documents (other than any failure covered by Section 6(a), (b) or
(g)), and such failure continues for thirty (30) days after receipt by the Company of notice
thereof.

     Upon the occurrence of any such Event of Default, except as provided in the following
paragraph, all unpaid principal and accrued interest under this Note shall become immediately due
and payable (A) upon election of the Holder, with respect to (a) through (d) and (f) through (j),
and (B) automatically, with respect to (e). Except as provided in the following paragraph, upon
the occurrence of any Event of Default, the Holder may, in addition to declaring all

22

 

amounts due hereunder to be immediately due and payable, pursue any available remedy, whether
at law or in equity, including, without limitation, exercising its rights under the other
Transaction Documents. If an Event of Default occurs, the Company shall pay to the Holder the
reasonable attorneys’ fees and disbursements and all other reasonable out-of-pocket costs incurred
by the Holder in order to collect amounts due and owing under this Note or otherwise to enforce the
Holder’s rights and remedies hereunder and under the other Transaction Documents.

     So long as the only Events of Default that have occurred and are continuing are Qualifying
Events of Default, upon the first occurrence of a Qualifying Event of Default which is not cured by
the Company or waived or rescinded by the Holder, the Holder’s right to accelerate the principal
and interest due under this Note shall be limited to one-third of the outstanding principal amount
and all accrued interest then due under this Note (the “First Default Amount”). The date
on which notice of the acceleration of the First Default Amount is given by the Holder is
hereinafter referred to as the “First Acceleration Date.” Upon the second occurrence of a
Qualifying Event of Default which is not cured or waived or rescinded by the Holder or upon the
continuation of an existing Qualifying Event of Default more than 90 days after the First
Acceleration Date and provided that the Holder shall have received the indefeasible payment in full
of the First Default Amount, the Holder’s right to accelerate the principal and interest due under
this Note shall be limited to one-half of the outstanding principal amount and all accrued interest
then due under this Note (the “Second Default Amount”); provided, however, that no such
acceleration shall be effective until 90 days after the First Acceleration Date. The date on which
notice of the acceleration of the Second Default Amount is given by the Holder is hereinafter
referred to as the “Second Acceleration Date.” Upon the third occurrence of a Qualifying
Event of Default which is not cured by the Company or waived or rescinded by the Holder or upon the
continuation of an existing Qualifying Event of Default more than 90 days after the Second
Acceleration Date and provided that the Holder shall have received the indefeasible payment in full
of the First Default Amount and the Second Default Amount, the Holder shall not have the right to
accelerate the remaining outstanding principal amount and all accrued interest then due under this
Note until 90 days after the Second Acceleration Date. The failure of the Company to indefeasibly
pay in full the First Default Amount or the Second Default Amount within three days of the First
Acceleration Date or the Second Acceleration Date, as applicable, shall constitute an additional
Event of Default hereunder and shall entitle the Holder, at its option, to declare the entire
principal amount of this Note and all accrued interest hereunder immediately due and payable. In
no event shall the Holder proceed against the collateral pursuant to the terms of the Security
Agreement in respect of one or more Qualifying Events of Default subject to the provisions of this
paragraph unless and until the Company shall have failed to pay the First Default Amount or the
Second Default Amount, as applicable, within three days of the First Acceleration Date or the
Second Acceleration Date, as applicable.

     7. No Waiver. To the extent permitted by applicable law, no delay or omission on the
part of the Holder in exercising any right under this Note shall operate as a waiver of such right
or of any other right of the Holder, nor shall any delay, omission or waiver on any one occasion be
deemed a bar to or waiver of the same or any other right on any future occasion.

     8. Amendments in Writing. Any term of this Note may be amended or waived upon the
written consent of the Company and the holders of Company Notes representing at least 50% of the
principal amount of Company Notes then outstanding (the “Majority Holders”);
provided,

23

 

that (x) any such amendment or waiver must apply to all outstanding Company Notes; and (y)
without the consent of the Holder hereof, no amendment or waiver shall (i) change the Stated
Maturity Date of this Note, (ii) reduce the principal amount of this Note or the interest rate due
hereon, (iii) change the Conversion Price or (iv) change the place of payment of this Note. No
such waiver or consent on any one instance shall be construed to be a continuing waiver or a waiver
in any other instance unless it expressly so provides.

     9. Waivers. The Company hereby forever waives presentment, demand, presentment for
payment, protest, notice of protest, notice of dishonor of this Note and all other demands and
notices in connection with the delivery, acceptance, performance and enforcement of this Note.

     10. Waiver of Jury Trial. THE COMPANY HEREBY WAIVES ITS RIGHT TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS NOTE OR ANY CONTEMPLATED TRANSACTION,
INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THE COMPANY HAS REVIEWED THIS
WAIVER WITH ITS COUNSEL.

     11. Secured Obligation. This Note is one of the Notes referred to in the Security
Agreement and is secured by the collateral described therein. The Security Agreement grants the
Holder certain rights with respect to such collateral upon an Event of Default.

     12. Governing Law; Consent to Jurisdiction. This Note shall be governed by and
construed under the law of the State of New York, without giving effect to the conflicts of law
principles thereof. The Company and, by accepting this Note, the Holder, each irrevocably submits
to the exclusive jurisdiction of the courts of the State of New York located in New York County and
the United States District Court for the Southern District of New York for the purpose of any suit,
action, proceeding or judgment relating to or arising out of this Note and the transactions
contemplated hereby. Service of process in connection with any such suit, action or proceeding may
be served on each party hereto anywhere in the world by the same methods as are specified for the
giving of notices under this Note. The Company and, by accepting this Note, the Holder, each
irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding
and to the laying of venue in such court. The Company and, by accepting this Note, the Holder,
each irrevocably waives any objection to the laying of venue of any such suit, action or proceeding
brought in such courts and irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.

     13. Costs. If action is instituted to collect on this Note, the Company promises to
pay all reasonable costs and expenses, including reasonable attorney’s fees, incurred in connection
with such action.

     14. Notices. All notices hereunder shall be given in writing and shall be deemed
delivered when received by the other party hereto at the address set forth in the Purchase
Agreement or at such other address as may be specified by such party from time to time in
accordance with the Purchase Agreement.

24

 

     15. Successors and Assigns. This Note shall be binding upon the successors or assigns
of the Company and shall inure to the benefit of the successors and assigns of the Holder.
