provision contained in the Series A Preferred Stock Purchase Agreement, except as

other than the State of Florida. In furtherance of the foregoing, the internal law of the State of

connection with any amendment of, or waiver or consent requested under, this Amendment or any
Transaction Document, except for waivers, amendments or consents (a) not originally requested by
the Company and (b) not involving a change to or modification of any of the Company’s obligations,
covenants or agreements hereunder.

     6. Interpretation.

     (a) Capitalized terms used herein without definition shall have the respective
definitions assigned to those terms in the Series A Preferred Stock Purchase Agreement.

mean “including without limitation,” (ii) the word “or” is not exclusive and (iii) the words
“herein,” “hereof,” “hereby,” “hereto” and “hereunder” refer to this Amendment as a whole.

     (c) Unless the context otherwise requires, references herein to Sections, Exhibits and
Schedules mean the Sections of, and the Exhibits and Schedules attached to, this Amendment.

a part of or to affect the meaning or interpretation of this Amendment. The Schedules and
Exhibits referred to herein shall be construed with and as an integral part of this
Amendment to the same extent as if they were set forth verbatim herein.

     (d) Each of the parties to this Amendment has had the benefit of counsel in connection
with its review and negotiation of this Amendment. Consequently, the parties confirm that
this Amendment shall not be construed on the basis of any presumption or rule requiring

EXHIBIT A-l

Series A Certificate of Designations

 

 

TERMS OF

SERIES A REDEEMABLE CONVERTIBLE PREFERRED STOCK

OF

XSTREAM SYSTEMS, INC.

     (1) Designation, Par Value and Number. This series of Preferred Stock shall be
designated as “Series A Redeemable Convertible Preferred Stock.” The Corporation shall have the
authority to issue 962,101 shares of the Series A Preferred with a par value of $.0001 per share.
In accordance with the terms hereof, each share of Series A Preferred shall have the same relative
rights as, and be identical in all respects with, each other share of Series A Preferred.

     (2) Dividends.

          a. General. When and as declared by the Board, and to the fullest extent permitted
under the General Corporation Law of the State of Delaware, the Corporation shall pay preferential
dividends on each issued and outstanding share of the Series A Preferred; provided, however, that
no dividend shall be declared on the Series A Preferred unless a pro rata amount (based upon
relative Liquidation Value) is declared on each of the other series of Pari Passu Preferred.
Subject to Section 6(b)(ii), dividends on each issued and outstanding share of Series A
Preferred shall be cumulative and shall accrue on a daily basis at a rate of 5% per annum of the
Series A Liquidation Value thereof (with such accrued and unpaid dividends compounding on each
annual anniversary of the Series A Original Issuance Date) from and including the Series A Original
Issuance Date to and including the first to occur of (i) the date on which the Series A Liquidation
Value of such share (plus all accrued and unpaid dividends thereon) is paid to the holder thereof
in connection with the liquidation of the Corporation, (ii) the date on which such share is
converted into shares of Common hereunder or (iii) the date on which such share is otherwise
acquired by the Corporation. Such dividends shall accrue whether or not they have been declared and
whether or not there are profits, surplus or other funds of the Corporation legally available for
the payment of dividends, and such dividends shall be cumulative such that all accrued and unpaid
dividends shall be fully paid or declared with funds irrevocably set apart for payment before any
dividends, distributions, redemptions or other payments may be made with respect to any Series A
Junior Securities. If, under Delaware law, any dividends cannot be declared and paid in full when
due, the full amount which can be paid shall be paid pro rata to the holders of the Series A
Preferred and the aggregated deficiency shall be increased as provided below.

          b. Distribution of Partial Dividend Payments. Except as otherwise provided herein, if
at any time the Corporation pays less than the total amount of dividends then accrued with respect
to the Series A Preferred, such payment shall be distributed pro rata among the holders thereof
based upon the aggregate accrued but unpaid dividends on the Series A Preferred held by each such
holder.

          c. Participation in Common Dividends. If the Corporation declares or pays a dividend
or makes any distribution on the Common, then the holders of the outstanding shares of Pari Passu
Preferred (on a Common Equivalent Basis as of the record date for such dividend or distribution)
and the holders of the Common shall share pro rata in such dividend or distribution.

 

 

     (3) Voting Rights.

          a. General. In addition to the rights provided by law and Sections 3(b), 3(c)
and 3(d) below, the holders of the Series A Preferred shall be entitled to notice of all meetings
of stockholders in accordance with the Corporation’s By-laws, and except as otherwise provided
herein or required by applicable law, the holders of the Series A Preferred shall be entitled to
vote on all matters submitted to the stockholders for a vote, voting as a single class with the
Common and other securities that vote with the Common, with the holders of Series A Preferred
entitled to one vote for each share of Common issuable upon conversion of the Series A Preferred
held as of the record date for such vote or, if no record date is specified, as of the date of such
vote.

          b. Actions Requiring the Consent of the Holders of Series A Preferred. So long as any
shares of Series A Preferred are outstanding, without the approval of at least a majority of the
shares of Series A Preferred then outstanding, the Corporation shall not file any resolution of the
Board with the Delaware Secretary of State that contains any provisions, or take any other action,
that would amend the terms of the Series A Preferred, increase the number of authorized Series A
Preferred, approve a reverse stock split or adversely affect or otherwise impair the rights or the
relative preferences or priorities of the holders of the Series A Preferred under this Certificate
of Incorporation or the By-laws.

          c.
Actions Requiring the Consent of the Holders of Pari Passu Preferred and Conversion
Common Shares. So long as any shares of Pari Passu Preferred or Conversion Common Shares are
outstanding, the Corporation shall not take, and shall not permit any of its Subsidiaries to take,
any of the following actions without the approval of the holders of at least a majority of the
shares of all of the Pari Passu Preferred and Conversion Common Shares, voting as a single class on
a Common Equivalent Basis, then outstanding:

     (i) amend this Certificate of Incorporation or the By-laws;

     (ii) except for Permitted Issuances, authorize, issue or enter into any agreement
providing for the issuance (contingent or otherwise) of any capital stock or other equity
securities of the Corporation ranking pari passu or senior to the Series A Preferred (or any
securities convertible into or exchangeable for any capital stock or other equity securities
of the Corporation ranking pari passu or senior to the Series A Preferred);

     (iii) except for the ratable payment of dividends on the Pari Passu Preferred,
directly or indirectly declare or pay any cash or property dividends or make any cash or
property distributions upon any of its capital stock or other equity securities;

     (iv) directly or indirectly redeem, purchase or otherwise acquire any of the
Corporation’s capital stock or other equity securities (including, without limitation,
Options) other than (A) the Pari Passu Preferred pursuant to the terms of this Certificate
of Incorporation, (B) repurchases of the Corporation’s securities from employees upon
termination of an employee’s employment with the Corporation pursuant to terms approved by
the Board, (C) repurchases of Options outstanding as of the First Closing

-2-

 

Date pursuant to the terms of such Options or (D) pursuant to the terms of the
Shareholders Agreement;

     (v) merge or consolidate with any Person (other than a wholly owned Subsidiary) or
take any action which results in a Change in Ownership;

     (vi) sell, license, lease or otherwise transfer all or substantially all of its assets to
any Person (other than to a wholly owned Subsidiary of the Corporation) in any transaction or
series of related transactions;

     (vii) liquidate, dissolve or effect a recapitalization, bankruptcy or reincorporation in
any form of transaction (including, without limitation, any reincorporation into a limited
liability company, a partnership or any other non-corporate entity that is treated as a partnership
for Federal income tax purposes);

     (viii) make any loans or advances to, guarantees for the benefit of, or investments in, any
Person (other than a wholly owned Subsidiary established under the laws of a jurisdiction of the
United States or any of its territorial possessions), except for (A) reasonable advances to
employees in the ordinary course of business consistent with past practice and (B) advances to
newly-hired employees in order to cover such employees’ relocation expenses;

     (ix) except as provided in the current Budget, create, incur, assume or suffer to exist
any Indebtedness;

     (x) create, incur, assume or suffer to exist any Liens other than (A) Permitted Liens
and (B) Liens incurred in connection with the incurrence of Indebtedness not prohibited by clause
(ix) above;

     (xi) acquire any interest in any company or business (whether by a purchase of assets,
purchase of stock, merger or otherwise), or enter into any joint venture, in either case, that is
material to the business of the Corporation and its Subsidiaries, taken as a whole (each, an
“Acquisition”), other than Acquisitions the aggregate value of which (after taking into account the
assumption of any Indebtedness or other liabilities in connection therewith) do not exceed $300,000
in any twelve-month period, measured after giving effect to any purchase price adjustments relating
thereto;

     (xii) become subject to (including, without limitation, by way of amendment to or
modification of) any agreement or instrument that by its terms would (under any circumstances)
restrict the Corporation’s right to perform the provisions of the Preferred Stock Purchase
Agreement, the Shareholders Agreement, the Registration Rights Agreement, this Certificate of
Incorporation or the By-laws;

     (xiii) except as provided in the current Budget, make or commit to make capital
expenditures for any fiscal year;

     (xiv) except as required by Section 6(b)(i), increase the size of the Board to a
number greater than seven (7);

     (xv) enter into or become a party to any license, agreement or other
arrangement after the First Closing Date with respect to Intellectual Property Rights
licensed to, or owned or developed by, the Corporation, except that the foregoing
shall not prevent the Corporation from entering into, or becoming a party to, any
such license, agreement or other arrangement that (A) has a term of one year or
less, (B) is nonexclusive and would be customary in connection with the sale of the
Corporation’s products or services, (C) relates to “off the shelf” software licenses
to the Corporation by a third party or (D) is approved by a majority of the Board
(including at least one of the Investor Directors); or

     (xvi) change the primary line of business of the Corporation from materials
identification, verification and analysis, and any related field, or enter into any
material new line of business.

          d. Election of Directors. Subject to Section 6(b)(i), for so
long as any shares of Pari Passu Preferred or Conversion Common Shares remain outstanding,
the holders of the Pari Passu Preferred and Conversion Common Shares, voting together as a
single class on a Common Equivalent Basis, shall be entitled to elect two (2) members of
the Board at each meeting or pursuant to each consent of the Corporation’s stockholders
for the election of directors, and to remove from office any such director and to fill any
vacancy caused by the resignation, death or removal of any such director.

     (4) Liquidation, Dissolution, etc.

          a. Significant Event. Upon any liquidation, Fundamental Change,
Change in Ownership, dissolution or winding up of the Corporation (whether voluntary or
involuntary) (each, a “Significant Event”):

     (i) Each holder of Series A Preferred shall be entitled to receive,
prior and in preference to any distribution or payment made upon any Series A Junior
Securities, an amount equal to (i) the aggregate Series A Liquidation Value of all
shares of Series A Preferred held by such holder plus (ii) all accrued and unpaid
dividends on such shares of Series A Preferred. If, upon any Significant Event, the
Corporation’s assets to be distributed among the holders of the Pari Passu Preferred
are insufficient to permit payment to such holders of the aggregate amount to which
they are entitled to be paid under this Section 4(a)(i) and the equivalent
provisions of the other series of Pari Passu Preferred, then the entire assets
available to be distributed to the Corporation’s stockholders shall be distributed
pro rata among such holders of the Pari Passu Preferred based upon the aggregate
Liquidation Value (plus all accrued and unpaid dividends) of the shares of Pari
Passu Preferred held by each such holder.

     (ii) After payment to the holders of the Series A Preferred of the
amounts set forth in the first sentence of Section 4(a)(i), the entire remaining
assets and funds of the Corporation legally available for distribution, if any,
shall be distributed pro rata among the holders of the Common and the holders of
the Pari Passu Preferred (on a Common Equivalent Basis).

-4-

 

          b. Form of Consideration. Whenever the distribution provided for in this Section
4 shall be payable in a form other than securities or cash, the value of such distribution
shall be the fair market value as determined in good faith by the Board, including a majority of
the Investor Directors.

          c. Distribution upon Change in Ownership. Upon any Significant Event effected as a
result of a Change in Ownership, any proceeds received by stockholders of the Corporation other
than holders of Pari Passu Preferred in accordance with the terms of such Pari Passu Preferred
(including, without limitation, any amounts received by any stockholders in respect of any
employment, non-competition, consulting or other similar agreement entered into in connection with
such Change in Ownership that, in the case of employment or consulting agreements, provide for
payments to such stockholder that are in excess of the compensation payable to such stockholder
prior to such Change in Ownership (other than, in the case of employment, for increases in annual
compensation not in excess of 20% of the annual compensation payable to such stockholder in the
last completed fiscal year prior to such Change in Ownership)) shall be construed as being received
by the Corporation and thereafter distributed to the holders of the Pari Passu Preferred and Common
in accordance with Section 4(a)(ii).

     (5) Redemptions.

          a. Redemption at the Option of Holders. At any time on or after March 14,
2012, upon the request of the holders of at least a majority of the then outstanding shares of
Series A Preferred, each of the holders of the then outstanding Series A Preferred shall have the
right (a “Redemption Right”) to require the Corporation to redeem all or any of their shares of
Series A Preferred at a price per share equal to the Series A Liquidation Value plus a rate of
return on such amount (after taking into account all dividends paid by the Corporation pursuant to
Section 2(a)) equal to 7% per annum, compounded annually. Any holder of Series A Preferred
may exercise his, her or its Redemption Right by delivering to the Corporation a Redemption Notice
on or after March 14, 2012, provided that holders of at least a majority of the then outstanding
shares of Pari Passu Preferred have requested a redemption pursuant to this Section 5(a)
and the equivalent provisions of the other series of Pari Passu Preferred. Within ten (10) days
after the date of a Redemption Notice delivered by any holder of Series A Preferred, the
Corporation shall notify all other holders of Pari Passu Preferred that the Redemption Right has
been exercised, and each other holder of Pari Passu Preferred shall have the right, exercisable by
written notice delivered to the Corporation within thirty (30) days after receipt of such notice
from the Corporation, to request that all or a portion of such other holder’s shares of Pari Passu
Preferred be redeemed on the Redemption Date together with the shares of Series A Preferred of the
holder who delivered the Redemption Notice. The Corporation shall be obligated to redeem the total
number of shares of Series A Preferred requested to be redeemed in accordance herewith on the
Redemption Date. For each share of Series A Preferred which is to be redeemed on a particular
Redemption Date in accordance with this Section 5 (a), the Corporation shall be obligated
on the date specified for redemption thereof in the written notice with respect thereto, to pay to
the holder thereof (upon surrender by such holder at the Corporation’s principal office of the
certificate representing such share) such amount specified in this Section 5(a) in
immediately available funds.

          b. Inadequate Funds: Redemption Notes. If the funds of the
Corporation

-5-

 

legally available for redemption of Series A Preferred on any Redemption Date are insufficient to
redeem the total number of shares of Series A Preferred and all other shares of Pari Passu
Preferred to be redeemed on such date: (i) those funds which are legally available shall be used to
redeem the maximum possible number of shares of Pari Passu Preferred ratably among the holders of
such shares to be redeemed based upon the aggregate amount to which they are entitled to be paid
under this Section 5 and the equivalent provisions of the other series of Pari Passu
Preferred; and (ii) with respect to those shares of Pari Passu Preferred requested to be redeemed
but for which funds are not legally available (the “Non-Funded Shares”), the Corporation shall
issue and deliver to each holder of Non-Funded Shares a promissory note (each a “Redemption Note”).
Each Redemption Note shall be payable one year from date of issuance and shall bear interest at the
rate of 8% per annum, compounded quarterly, and shall have an aggregate principal amount per
Non-Funded Share equal to the Series A Liquidation Value plus a rate of return on such amount
(after taking into account all dividends paid by the Corporation pursuant to Section 2(a))
equal to 7% per annum, compounded annually. A Redemption Note may be prepaid by the Company at any
time without penalty. The issuance of Redemption Notes shall be made without charge to the holders
of the Non-Funded Shares receiving such Redemption Notes for any issuance tax in respect thereof or
other cost incurred by the Corporation in connection with the issuance thereof, and the Corporation
shall pay the fees and expenses of each holder of Non-Funded Shares in connection with the issuance
of Redemption Notes, including reasonable attorney’s fees and expense. Subject to the terms of any
then existing senior debt or credit facility, the terms and documentation relating to each
Redemption Note shall provide that the debt obligation evidenced thereby shall at all times be pari
passu with the most senior debt or credit facility of the Corporation outstanding at any time
during the term of the Redemption Note. Each Redemption Note shall also contain customary terms and
conditions, including, without limitation, a cross-acceleration provision with respect to any
amount of Indebtedness of the Company or any of its Subsidiaries and appropriate negative
covenants, including, without limitation, negative covenants prohibiting the Corporation, without
the consent of the holders of a majority of aggregate principal amount of all of the Redemption
Notes outstanding, from taking, or permitting any of its Subsidiaries to take, any of the actions
specified in Sections 3(b)(i) - xvi.

          c. Reissuance of Certificate. If fewer than the total number of shares of Series A
Preferred represented by any certificate are redeemed in any installment, a new certificate
representing the number of unredeemed shares of Series A Preferred (other than any Non-Funded
Shares) will be issued to the holder thereof without cost to such holder promptly after surrender
of the certificate representing the redeemed shares of Series A Preferred.

          d. Redeemed or Otherwise Acquired Shares. All rights pertaining to shares of the
Series A Preferred that are redeemed or otherwise acquired by the Corporation and, subject to
Section 5(b), all rights pertaining to shares that are deemed to be Non-Funded Shares,
shall cease, and such shares  shall not thereafter be (i) reissued, sold or transferred, (ii)
entitled to any dividends accruing after the date of redemption or acquisition or (iii) deemed to
be issued and outstanding for any purpose whatsoever. The shares of Series A Preferred not redeemed
(other than any Non-Funded Shares) shall remain issued and outstanding and entitled to all the
rights and preferences provided herein.

     (6) Events of Noncompliance.

          a. Definition. An “Event of Noncompliance” shall
be deemed to have occurred if:

     (i) the Corporation shall fail to make any redemption payment required under Section 5
or the equivalent provisions of the other series of Pari Passu Preferred (whether or not
such payment is legally permissible or is prohibited by any agreement to which the
Corporation is subject);

     (ii) (v) the Corporation breaches any of its covenants or agreements contained in
the Preferred Stock Purchase Agreement, which breach has, or is more likely than not to
have, an adverse effect of $100,000 or more in the aggregate on the holders of the Pari
Passu Preferred, (x) such breach does not result directly from action by the Corporation at
express the direction of the Board (including in such direction a majority of the Investor
Directors), (y) the Corporation fails to cure such breach within 30 days of written notice
thereof from any holder of the Pari Passu Preferred and (z) the holders of at least a
majority of the outstanding shares of Pari Passu Preferred after such 30-day period send a
notice of such Event of Noncompliance to the Corporation;

     (iii) (x) any representation or warranty made by the Corporation under the
Preferred Stock Purchase Agreement shall have been untrue or incorrect in any material
respect when made, the result of which has, or is more likely than not to have, an adverse
effect of $100,000 or more on (A) the condition (financial or otherwise), operating results,
business, assets, operations, employee relations or client relations of the Corporation,
taken as a whole (other than to the extent resulting from a change in accounting methods
required by GAAP) or (B) the holders of the Pari Passu Preferred, (y) the Corporation fails
to cure such breach within 30 days of written notice thereof from any holder of the Pari
Passu Preferred and (z) the holders of at least a majority of the outstanding shares of Pari
Passu Preferred send a notice of such Event of Noncompliance to the Corporation;

     (iv) the Corporation shall commence or enter into any bankruptcy,
receivership, liquidation or assignment for the benefit of any creditors;

     (v) the Corporation shall default under one or more indentures, agreements or
other instruments under which any Indebtedness aggregating at least $100,000 of the
Corporation or any of its Subsidiaries is or may be issued, and such default shall continue
for a period of time sufficient to permit the acceleration of the maturity of any
Indebtedness of the Corporation or any of its Subsidiaries outstanding thereunder (which
default has not been cured or waived), other than a default which directly results from
action by the Corporation at the express direction of the Board (including in such direction
a majority of the Investor Directors); or

     (vi) a judgment in excess of $500,000 is rendered against the Corporation and, within 60
days after entry thereof, such judgment is not discharged or execution thereof stayed
pending appeal, or within 60 days after the expiration of such stay, such judgment

-7-

 

is not discharged.

          b. Consequences of Events of Noncompliance.

     (i) Additional Directors. Upon the occurrence of an Event of Noncompliance and
for so long as such Event of Noncompliance continues, the holders of Pari Passu Preferred and
Conversion Common Shares shall be entitled to appoint such number of additional Investor Directors
to the Board (selected by the holders of a majority of the Pari Passu Preferred and Conversion
Common Shares) such that the holders of Pari Passu Preferred and Conversion Common Shares have
appointed a majority of the Board. Upon notice from the holders of a majority of the outstanding
Pari Passu Preferred and Conversion Common Shares, voting as a single class on a Common Equivalent
Basis, then outstanding that they intend to exercise their rights under this Section 6(b)(i), the
Corporation shall immediately take whatever action is necessary so as to effectuate this
Section 6(b)(i), including, without limitation, increasing the size of the Board and
electing such additional Investor Directors.

     (ii) Increased Dividend Rate. Upon the occurrence of an Event of Noncompliance
and for so long as such Event of Noncompliance continues, the dividend rate on the Series A
Preferred set forth in Section 2(a) shall be increased from 5% to 7% per annum.

     (iii) Redemption of Pari Passu Preferred. Upon the occurrence of an Event of
Noncompliance and for so long as such Event of Noncompliance continues, the holders of a majority
of the shares of Pari Passu Preferred then outstanding may require by notice given to the
Corporation that all of the shares of Pari Passu Preferred be immediately (and in no event later
than five business days after such request) redeemed by the Corporation at a price per share of
Pari Passu Preferred equal to the their respective Liquidation Values plus a rate of return on such
amount (after taking into account all dividends paid by the Corporation pursuant to Section
2(a)) equal to 7% per annum, compounded annually.

     (iv) Inadequate Funds. If the funds of the Corporation legally available for
redemption of Pari Passu Preferred pursuant to Section 6(b)(iii) are insufficient to redeem
all shares of Pari Passu Preferred, the provisions of Sections 5(b) and (c) shall apply to
the same extent as if such provisions were set forth in their entirety in this Section 6(b)(iv).

     (v) Reissuance of Certificate. If fewer than the total number of shares of
Series A Preferred or Conversion Common Shares represented by any certificate are redeemed in any
installment pursuant to Section 6(b)(iv), a new certificate representing the number of
unredeemed shares of such Series A Preferred or Conversion Common Shares, as the case may be, will
be issued to the holder thereof without cost to such holder promptly after surrender of the
certificate representing the redeemed shares of Series A Preferred or Conversion Common Shares, as
the case may be.

          c. No Limitation of Rights. If any Event of Noncompliance exists, each

-8-

 

holder of Series A Preferred shall also have any other rights that such holder is entitled to under
any contract or agreement at any time and any other rights that such holder may have pursuant to
applicable law.

          d. Survival of Representations and Warranties. For the purposes of
determining an Event of Noncompliance, the representations and warranties referred to in
Section 6(a)(iii) shall have the respective survival periods set forth in the
Preferred Stock Purchase Agreement.

     (7) Conversion.

          a. Conversion Procedure.

     (i) At any time and from time to time, a holder of Series A Preferred shall have
the right to convert all or any portion of its shares of Series A Preferred into the number
of shares of Common computed by dividing (x) the aggregate Series A Liquidation
Value of the shares of Series A Preferred to be converted by (y) the Series A Conversion
Price then in effect.

     (ii) All shares of Series A Preferred shall automatically convert into Common
(pursuant to the computation set forth in Section 7(a)(i)) upon (A) the affirmative written
consent of the holders of at least a majority of the outstanding shares of Pari Passu
Preferred or (B) receipt by the Corporation of total gross offering proceeds of at least
$50,000,000 from the sale of shares of Common pursuant to the Corporation’s firm commitment
underwritten Public Offering of the Common, at a gross price per share not less than $16 (as
adjusted to reflect stock splits, stock dividends, stock combinations, recapitalizations and
like occurrences) (a “Qualified IPO”).

     (iii) Each conversion of Series A Preferred shall be deemed to have been effected
as of the close of business on the earlier of (A) the date specified in the affirmative
written consent of the holders of at least a majority of the outstanding shares of Series A
Preferred or (B) the date immediately prior to the closing date of a Qualified IPO (any such
date referred to in clause (A) or (B) being referred to as a “Conversion Date”). At the time
any such conversion has been effected, the rights of the holder of the shares of Series A
Preferred converted as a holder of Series A Preferred shall cease and the Person or Persons
in whose name or names any certificate or certificates for shares of Common are to be issued
upon such conversion shall be deemed to have become the holder or holders of record of the
shares of Common represented thereby.

     (iv) As soon as possible after a conversion has been effected (but in any event
within five (5) business days in the case of subparagraph (A) below), the Corporation shall
deliver to the converting holder:

               (A) certificates representing the number of shares of Common issuable by reason of
such conversion in such name or names and such denomination or denominations as the
converting holder has specified; and

               (B) a certificate representing any shares of Series A Preferred

-9-

 

which were represented by the certificate or certificates delivered to the Corporation in
connection with such conversion but which were not converted.

     (v) The issuance of certificates for shares of Common upon conversion of Series A
Preferred shall be made without charge to the holders of such Series A Preferred or Common for any
issuance tax in respect thereof or other cost incurred by the Corporation in connection with such
conversion and the related issuance of shares of Common. Upon conversion of each share of Series A
Preferred, the Corporation shall take all such actions as are necessary in order to insure that the
Common issuable with respect to such conversion shall be validly issued, fully paid and
nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the
issuance thereof.

     (vi) The Corporation shall not close its books against the transfer of Series A Preferred
or of Common issued or issuable upon conversion of Series A Preferred in any manner that interferes
with the timely conversion of Series A Preferred. The Corporation shall assist and cooperate with
any holder of shares of Series A Preferred required to make any governmental filings or obtain any
governmental approval prior to or in connection with any conversion of shares hereunder (including,
without limitation, making any filings required to be made by the Corporation).

     (vii) The Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common, solely for the purpose of issuance upon the conversion of shares of
the Series A Preferred, such number of shares of Common as are issuable upon the conversion of all
outstanding Series A Preferred. All shares of Common which are so issuable shall, when issued, be
duly and validly issued, fully paid and nonassessable and free from all taxes, liens, charges and
encumbrances. The Corporation shall take all such actions as may be necessary to insure that all
such shares of Common may be so issued without violation of any applicable law or governmental
regulation or any requirements of any domestic securities exchange upon which shares of Common may
be listed (except for official notice of issuance which shall be delivered immediately by the
Corporation upon each such issuance). The Corporation shall not take any action that would cause
the number of authorized but unissued shares of Common to be less than the number of such shares
required to be reserved hereunder for issuance upon conversion of the Series A Preferred.

     (viii) If any fractional interest in a share of Common would, except for the provisions of
this subparagraph, be delivered upon any conversion of the Series A Preferred, the Corporation, in
lieu of delivering the fractional share therefor, may pay an amount to the holder thereof equal to
the fair market value per share of Common as of the date of conversion as determined in good faith
by the Board, including a majority of the Investor Directors, multiplied by such fractional
interest; provided, however, that in the case of a Qualified IPO the fair market value per share
of Common shall be the gross price per share of Common in such Qualified IPO. The determination as
to whether or not to make any cash payment in lieu of the issuance of fractional shares shall be
based upon the total number of shares of Series A Preferred being converted at any one time by the
holder thereof, not upon each share of Series A Preferred being converted.

-10-

 

     (ix) All certificates representing shares of Series A Preferred which are required
to be surrendered for conversion in accordance with the provisions hereof shall, from and after the
Conversion Date, be deemed to have been retired and cancelled, and  the shares of Series A
Preferred converted pursuant to this Section 7 represented thereby shall, from and after
the Conversion Date, be deemed to have been converted into Common for all purposes, notwithstanding
any failure of the holder or holders thereof to surrender such certificates on or prior to the
Conversion Date. The Corporation from time to time may take such appropriate corporate action as
may be necessary to reduce the authorized number of shares of the Series A Preferred Stock
accordingly.

     b. Conversion Price.

     (i) The initial Series A Conversion Price shall be $3.7999696 per share of Common
(subject to adjustment in the event of stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences). In order to prevent dilution of the conversion rights
granted under this Section 7, the Series A Conversion Price shall be subject to adjustment
from time to time pursuant to this Section 7(b).

     (ii) If and whenever on or after the Series A Original Issuance Date the Corporation
issues or sells or, in accordance with this Section 7, is deemed to have issued or sold,
any shares of its Common for a consideration per share less than the Series A Conversion Price in
effect immediately prior to the time of such issuance, then immediately upon such issuance or sale
or deemed issuance or sale the Series A Conversion Price shall be reduced to the conversion price
determined by dividing (A) the sum of (1) the product derived by multiplying the Series A
Conversion Price in effect immediately prior to such issuance or sale by the number of shares of
Common Deemed Outstanding immediately prior to such issuance or sale, plus (2) the consideration,
if any, received by the Corporation upon such issuance or sale, by (B) the number of shares of
Common Deemed Outstanding immediately after such issue or sale.

     (iii) Notwithstanding the foregoing, there shall be no adjustment in the Series A
Conversion Price as a result of any issuance or sale (or deemed issuance or sale) of:

     (A) shares of Common issued upon conversion of the Series A Preferred;

     (B) shares of Common issued upon the exercise of Options or other Convertible
Securities outstanding as of the First Closing Date;

     (C) securities issued pursuant to a Board-approved (including at least one of
the Investor Directors) bona fide acquisition of an entity by merger, purchase of
substantially all of the assets or other reorganization;

     (D) shares of Common issued to Catalyst pursuant to the Options granted
under the Catalyst Letter Agreements;

     (E) shares of Common or other securities issued as a dividend or distribution
on, or in connection with a split of or recapitalization of,

-11-

 

any of the capital stock of the Corporation;

     (F) up to an aggregate of 250,000 shares of Common reserved for issuance
per year pursuant to the Option Plan (subject to adjustment in the event of
stock splits, stock dividends, stock combinations, recapitalizations and like
occurrences) and shares of Common reserved for issuance pursuant to the
Option Plan in lieu of the repayment of certain salary deferrals as approved
by a majority of the Board (including at least one of the Investor
Directors), which foregoing shares may be subject to Options or restricted
stock awards granted under the Option Plan; provided that any Options that
expire or terminate unexercised or any restricted stock awards that are
repurchased by the Corporation pursuant to the terms of such award shall not
be counted toward the maximum number set forth in this subparagraph (F)
unless and until such shares are subject to new restricted stock awards (or
new Options) pursuant to the terms of the Option Plan;

     (G) shares of Common issued or issuable (including options to acquire
such shares of Common) to suppliers or third-party service providers in
connection with the provision of goods or services pursuant to transactions
in the ordinary course of business and approved by a majority of the Board,
including at least one of the Investor Directors;

     (H) shares of Common issued or issuable in connection with
bona-fide sponsored research, collaboration, technology license, development,
OEM, marketing or other similar agreements or strategic partnerships or joint
ventures entered into in the ordinary course of business and approved by a
majority of the Board, including at least one of the Investor Directors (and
by at least a majority of the shares of Pari Passu Preferred and Conversion
Common Shares, voting as a single class on a Common Equivalent Basis, then
outstanding, if required pursuant to Section 3(c)); or

     (I) securities issued in connection with a Qualified IPO;

provided that the aggregate number of shares of Common issued or issuable pursuant to
clauses (G) and (H) above shall not exceed 100,000 in any twelve-month period;

          c. Effect on Conversion Price of Certain Events. For purposes of
determining the Series A Conversion Price under Section 7, the following shall be
applicable:

     (i) Issuance of Options. If the Corporation in any manner grants, issues
or sells any Options (other than any Options permitted by Section 7(b)(iii)) and the
price per share for which Common is issuable upon the exercise of such Options, or upon
conversion or exchange of any Convertible Securities issuable upon exercise of such Options,
is less than the Series A Conversion Price in effect immediately prior to the time of the
granting, issuance or sale of such Options, then the total maximum number of

-12-

 

shares of Common issuable upon the exercise of such Options or upon conversion or exchange of the
total maximum amount of such Convertible Securities issuable upon the exercise of such Options
shall be deemed to be outstanding and to have been issued and sold by the Corporation at the time
of the granting, issuance or sale of such Options for such price per share. For purposes of this
paragraph, the “price per share for which Common is issuable” shall be determined by
dividing (A) the sum of (1) the total amount, if any, received or receivable by the
Corporation as consideration for the granting, issuance or sale of such Options, plus (2) the
minimum aggregate amount of additional consideration payable to the Corporation upon exercise of
all such Options, plus (3) in the case of such Options which relate to Convertible Securities, the
minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the
issuance or sale of such Convertible Securities and the conversion or exchange thereof, by (B) the
total maximum number of shares of Common 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. No further adjustment of the Conversion Price shall be made when Convertible Securities
are actually issued upon the exercise of such Options or when Common is actually issued upon the
exercise of such Options or the conversion or exchange of such Convertible Securities.

     (ii) Issuance of Convertible Securities. If the Corporation in any manner issues
or sells any Convertible Securities and the price per share for which Common is issuable upon
conversion or exchange thereof is less than the Series A Conversion Price in effect immediately
prior to the time of such issuance or sale, then the maximum number of shares of Common issuable
upon conversion or exchange of such Convertible Securities shall be deemed to be outstanding and to
have been issued and sold by the Corporation at the time of the issuance or sale of such
Convertible Securities for such price per share. For the purposes of this paragraph, the “price per
share for which Common is issuable” shall be determined by dividing (A) the sum of (1) the
total amount received or receivable by the Corporation as consideration for the issue or sale of
such Convertible Securities, plus (2) the minimum aggregate amount of additional consideration, if
any, payable to the Corporation upon the conversion or exchange thereof, by (B) the total maximum
number of shares of Common issuable upon the conversion or exchange of all such Convertible
Securities. No further adjustment of the Series A Conversion Price shall be made when Common is
actually issued upon the conversion or exchange of such Convertible Securities, and if any such
issuance or sale of such Convertible Securities is made upon exercise of any Options for which
adjustments of the Series A Conversion Price had been or are to be made pursuant to other
provisions of this Section 7, no further adjustment of the conversion price shall be made
by reason of such issue or sale.

     (iii) Change in Option Price or Conversion Rate. If the purchase price provided for
in any Options, the additional consideration, if any, payable upon the conversion or exchange of
any Convertible Securities or the rate at which any Convertible Securities are convertible into or
exchangeable for Common changes at any time, the Series A Conversion Price in effect at the time of
such change shall be immediately adjusted to the Series A Conversion Price that would have been in
effect at such time had such Options or Convertible Securities still outstanding provided for such

-13-

 

changed purchase price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold; provided, that, if such adjustment of the Series A
Conversion Price would result in an increase in the Series A Conversion Price then in effect, the
Corporation will promptly give all holders of Series A Preferred written notice of such increase.
For purposes of this Section 7(c)(iii), if the terms of any Option or Convertible Security
that was outstanding as of the Series A Original Issuance Date are changed in the manner described
in the immediately preceding sentence, then such Option or Convertible Security and the Common
deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued
as of the date of such change; provided, that, no such change shall at any time cause the Series A
Conversion Price hereunder to be increased.

     (iv) Treatment of Expired Options and Unexercised Convertible Securities. Upon
the expiration of any Option or the termination of any right to convert or exchange any Convertible
Security without the exercise of any such Option or right, the Series A Conversion Price then in
effect hereunder shall be adjusted immediately to the Series A Conversion Price that would have
been in effect at the time of such expiration or termination had such Option or Convertible
Security, to the extent outstanding immediately prior to such expiration or termination, never been
issued; provided, that, if such expiration or termination would result in an increase in the Series
A Conversion Price then in effect, the Corporation will promptly give all holders of Series A
Preferred written notice of such increase. For purposes of this Section 7(c)(iv), the expiration or termination of any Option or Convertible Security that was outstanding as of
the Series A Original Issuance Date shall not cause the Series A Conversion Price hereunder to be
adjusted unless, and only to the extent that, a change in the terms of such Option or Convertible
Security caused it to be deemed to have been issued after the Series A Original Issuance Date.

     (v) Calculation of Consideration Received. If any Common, Option or Convertible
Security is issued or sold or deemed to have been issued or sold for cash, the consideration
received therefor shall be deemed to be the amount received by the Corporation therefor (net of
discounts, commissions and related expenses). If any Common, Option or Convertible Security is
issued or sold for a consideration other than cash, the amount of the consideration other than cash
received by the Corporation shall be the fair market value of such consideration as determined in
good faith by the Board. If any Common, Option or Convertible Security is issued to the owners of
the non-surviving entity in connection with any merger in which the Corporation is the surviving
corporation, the amount of consideration therefor shall be deemed to be the fair value of such
portion of the net assets and business of the non-surviving entity as is attributable to such
Common, Option or Convertible Security, as the case may be. The fair value of any consideration
other than cash and securities shall be the fair market value as determined in good faith by the
Board.

     (vi) Integrated Transactions. In case any Option is issued in connection with the
issuance or sale of other securities of the Corporation, together comprising one integrated
transaction in which no specific exercise price is allocated to such Option by the parties thereto,
the Option shall be deemed to have been issued at an exercise price of
$0.01.

-14-

 

     (vii) Treasury Shares. The number of shares of Common outstanding at any given time
shall not include shares owned or held by or for the account of the Corporation, and the
disposition of any shares so owned or held shall be considered an issuance or sale of such shares.

     (viii) Record Date. If the Corporation takes a record of the holders of Common for the
purpose of entitling them (A) to receive a dividend or other distribution payable in Common,
Options or in Convertible Securities or (B) to subscribe for or purchase Common, Options or
Convertible Securities, then such record date shall be deemed to be the date of the issue or sale
of the shares of Common deemed to have been issued or sold upon the declaration of such dividend
or upon the making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

     (ix)
Subdivisions or Combinations of Common. If the Corporation at
any time subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes
of its outstanding shares of Common into a greater number of shares, the Series A Conversion Price
in effect immediately prior to such subdivision shall be reduced proportionately, and if the
Corporation at any time combines (by reverse stock split or otherwise) one or more classes of its
outstanding shares of Common into a smaller number of shares, the Series A Conversion Price in
effect immediately prior to such combination shall be increased proportionately.

     (x) Recapitalization, Reorganization, Reclassification, Consolidation, Merger
or_Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of
all or substantially all of the Corporation’s assets or other transaction, in each case which is
effected in such a manner that the holders of Common are entitled to receive (either directly or
upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common,
is referred to herein as an “Organic Change” Prior to the consummation of any Organic Change, the
Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the
holders of a majority of the Series A Preferred then outstanding) to insure that each of the
holders of Series A Preferred shall thereafter have the right to acquire and receive, in lieu of or
in addition to (as the case may be) the shares of Common immediately theretofore acquirable and
receivable upon the conversion of such holder’s Series A Preferred, such shares of stock,
securities or assets as such holder would have received in connection with such Organic Change if
such holder had converted its Series A Preferred immediately prior to such Organic Change. In each
such case, the Corporation shall also make appropriate provisions (in form and substance reasonably
satisfactory to the holders of a majority of the Series A Preferred then outstanding) to insure
that the provisions of this Section 7(c)shall thereafter be applicable to the securities
issued in exchange for the Series A Preferred (including, in the case of any such consolidation,
merger or sale in which the successor entity or purchasing entity is other than the Corporation and
the value for the Common reflected by the terms of such consolidation, merger or sale is less than
the Series A Conversion Price in effect immediately prior to such consolidation, merger or sale, an
immediate adjustment of the Series A Conversion Price to the value for the

-15-

 

Common so reflected and a corresponding immediate adjustment in the number of shares of
Common acquirable and receivable upon conversion of Series A Preferred). The Corporation
shall not effect any such consolidation, merger or sale, unless prior to the consummation
thereof, the successor entity (if other than the Corporation) resulting from consolidation
or merger or the entity purchasing such assets assumes by written instrument (in form and
substance satisfactory to the holders of a majority of the Series A Preferred then
outstanding) the obligation to deliver to each such holder such shares of stock, securities
or assets as, in accordance with the foregoing provisions, such holder may be entitled to
acquire.

     (xi) Certain Other Events. If any event occurs of the type contemplated by
the provisions of this Section 7 but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights, phantom stock
rights or other rights with equity features), then the Board shall make an appropriate
adjustment in the Series A Conversion Price so as to protect the rights of the holders of
Series A Preferred; provided, that, no such adjustment shall increase the Series A Conversion
Price as otherwise determined pursuant to this Section 7 or decrease the number of
shares of Common issuable upon conversion of each share of Series A Preferred.

     d. Notices.

     (i) Immediately upon any adjustment of the Series A Conversion Price, the
Corporation shall give written notice thereof to all holders of Series A Preferred, setting
forth in reasonable detail and certifying the calculation of such adjustment.

     (ii) The Corporation shall give written notice to all holders of Series A
Preferred at least 10 days prior to the date on which the Corporation closes its books or

     (iii) The Corporation shall also give written notice to the holders of Series A

stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or
mutilated certificate, and dividends shall accrue on the Common or Series A Preferred represented

     (2) Dividends.

          a. General. When and as declared by the Board, and to the fullest extent
permitted under the General Corporation Law of the State of Delaware, the Corporation shall pay

material to the business of the Corporation and its Subsidiaries, taken as a whole (each, an
“Acquisition”), other than Acquisitions the aggregate value of which (after taking into account the
assumption of any Indebtedness or other liabilities in connection therewith) do not exceed $300,000
in any twelve-month period, measured after giving effect to any purchase price adjustments relating
thereto;

     (xii) become subject to (including, without limitation, by way of amendment to or
modification of) any agreement or instrument that by its terms would (under any circumstances)
restrict the Corporation’s right to perform the provisions of the Preferred Stock Purchase
Agreement, the Shareholders Agreement, the Registration Rights Agreement, this Certificate of
Incorporation or the By-laws;

     (xiii) except as provided in the current Budget, make or commit to make capital
expenditures for any fiscal year;

     (xiv)
except as required by Section 6(b)(i), increase the size of the Board to a
number greater than seven (7);

-3-

 

     (xv) enter into or become a party to any license, agreement or other arrangement
after the First Closing Date with respect to Intellectual Property Rights licensed to, or
owned or developed by, the Corporation, except that the foregoing shall not prevent the
Corporation from entering into, or becoming a party to, any such license, agreement or other
arrangement that (A) has a term of one year or less, (B) is nonexclusive and would be
customary in connection with the sale of the Corporation’s products or services, (C) relates
to “off the shelf” software licenses to the Corporation by a third party or (D) is approved
by a majority of the Board (including at least one of the Investor Directors); or

     (xvi) change the primary line of business of the Corporation from materials
identification, verification and analysis, and any related field, or enter into any material
new line of business.

          d. Election of Directors. Subject to Section 6(b)(i), for so long as
any shares
of Pari Passu Preferred or Conversion Common Shares remain outstanding, the holders of the Pari
Passu Preferred and Conversion Common Shares, voting together as a single class on a Common
Equivalent Basis, shall be entitled to elect two (2) members of the Board at each meeting or
pursuant to each consent of the Corporation’s stockholders for the election of directors, and to
remove from office any such director and to fill any vacancy caused by the resignation, death or
removal of any such director.

     (4) Liquidation, Dissolution, etc.

          a. Significant Event. Upon any liquidation, Fundamental Change, Change in
Ownership, dissolution or winding up of the Corporation (whether voluntary or involuntary)
(each, a “Significant Event”):

     (i) Each holder of Series B Preferred shall be entitled to receive, prior and
in preference to any distribution or payment made upon any Series B Junior Securities, an
amount equal to (i) the aggregate Series B Liquidation Value of all shares of Series B
Preferred held by such holder plus (ii) all accrued and unpaid dividends on such shares of
Series B Preferred. If, upon any Significant Event, the Corporation’s assets to be
distributed among the holders of the Pari Passu Preferred are insufficient to permit
payment to such holders of the aggregate amount to which they are entitled to be paid under
this Section 4(a)(i) and the equivalent provisions of the other series of Pari
Passu Preferred, then the entire assets available to be distributed to the Corporation’s
stockholders shall be distributed pro rata among such holders of the Pari Passu Preferred
based upon the aggregate Liquidation Value (plus all accrued and unpaid dividends) of the
shares of Pari Passu Preferred held by each such holder.

     (ii) After payment to the holders of the Series B Preferred of the amounts set
forth in the first sentence of Section 4(a)(i), the entire remaining assets and
funds of the Corporation legally available for distribution, if any, shall be distributed
pro rata among the holders of the Common and the holders of the Pari Passu Preferred (on a
Common Equivalent Basis).

-4-

 

          b. Form of Consideration. Whenever the distribution provided for in this
Section 4 shall be payable in a form other than securities or cash, the value of such distribution
shall be the fair market value as determined in good faith by the Board, including a majority of
the Investor Directors.

          c. Distribution upon Change in Ownership. Upon any Significant Event effected
as a result of a Change in Ownership, any proceeds received by stockholders of the Corporation
other than holders of Pari Passu Preferred in accordance with the terms of such Pari Passu
Preferred (including, without limitation, any amounts received by any stockholders in respect of
any employment, non-competition, consulting or other similar agreement entered into in connection
with such Change in Ownership that, in the case of employment or consulting agreements, provide
for payments to such stockholder that are in excess of the compensation payable to such
stockholder prior to such Change in Ownership (other than, in the case of employment, for
increases in annual compensation not in excess of 20% of the annual compensation payable to such
stockholder in the last completed fiscal year prior to such Change in Ownership)) shall be
construed as being received by the Corporation and thereafter distributed to the holders of the
Pari Passu Preferred and Common in accordance with Section 4(a)(ii).

     (5) Redemptions.

          a. Redemption at the Option of Holders. At any time on or after March 14,
2012, upon the request of the holders of at least a majority of the then outstanding shares of
Series B Preferred, each of the holders of the then outstanding Series B Preferred shall have the
right (a “Redemption Right” to require the Corporation to redeem all or any of their shares of
Series B Preferred at a price per share equal to the Series B Liquidation Value plus a rate of
return on such amount (after taking into account all dividends paid by the Corporation pursuant to
Section 2(a)) equal to 7% per annum, compounded annually. Any holder of Series B Preferred may
exercise his, her or its Redemption Right by delivering to the Corporation a Redemption Notice on
or after March 14, 2012, provided that holders of at least a majority of the then outstanding
shares of Pari Passu Preferred have requested a redemption pursuant to this Section 5(a) and the
equivalent provisions of the other series of Pari Passu Preferred. Within ten (10) days after the
date of a Redemption Notice delivered by any holder of Series B Preferred, the Corporation shall
notify all other holders of Pari Passu Preferred that the Redemption Right has been exercised, and
each other holder of Pari Passu Preferred shall have the right, exercisable by written notice
delivered to the Corporation within thirty (30) days after receipt of such notice from the
Corporation, to request that all or a portion of such other holder’s shares of Pari Passu Preferred
be redeemed on the Redemption Date together with the shares of Series B Preferred of the holder who
delivered the Redemption Notice. The Corporation shall be obligated to redeem the total number of
shares of Series B Preferred requested to be redeemed in accordance herewith on the Redemption
Date. For each share of Series B Preferred which is to be redeemed on a particular Redemption Date
in accordance with this Section 5(a), the Corporation shall be obligated on the date
specified for redemption thereof in the written notice with respect thereto, to pay to the holder
thereof (upon surrender by such holder at the Corporation’s principal office of the certificate
representing such share) such amount specified in this Section 5(a) in immediately
available funds.

          b. Inadequate Funds; Redemption Notes. If the funds of the Corporation

-5-

 

legally available for redemption of Series B Preferred on any Redemption Date are insufficient to
redeem the total number of shares of Series A Preferred and all other shares of Pari Passu
Preferred to be redeemed on such date: (i) those funds which are legally available shall be used to
redeem the maximum possible number of shares of Pari Passu Preferred ratably among the holders of
such shares to be redeemed based upon the aggregate amount to which they are entitled to be paid
under this Section 5 and the equivalent provisions of the other series of Pari Passu
Preferred; and (ii) with respect to those shares of Pari Passu Preferred requested to be redeemed
but for which funds are not legally available (the “Non-Funded Shares”), the Corporation shall
issue and deliver to each holder of Non-Funded Shares a promissory note (each a “Redemption Note”).
Each Redemption Note shall be payable one year from date of issuance and shall bear interest at the
rate of 8% per annum, compounded quarterly, and shall have an aggregate principal amount per
Non-Funded Share equal to the Series B Liquidation Value plus a rate of return on such amount
(after taking into account all dividends paid by the Corporation pursuant to Section 2(a))
equal to 7% per annum, compounded annually. A Redemption Note may be prepaid by the Company at any
time without penalty. The issuance of Redemption Notes shall be made without charge to the holders
of the Non-Funded Shares receiving such Redemption Notes for any issuance tax in respect thereof or
other cost incurred by the Corporation in connection with the issuance thereof, and the Corporation
shall pay the fees and expenses of each holder of Non-Funded Shares in connection with the issuance
of Redemption Notes, including reasonable attorney’s fees and expense. Subject to the terms of any
then existing senior debt or credit facility, the terms and documentation relating to each
Redemption Note shall provide that the debt obligation evidenced thereby shall at all times be pari
passu with the most senior debt or credit facility of the Corporation outstanding at any time
during the term of the Redemption Note. Each Redemption Note shall also contain customary terms and
conditions, including, without limitation, a cross-acceleration provision with respect to any
amount of Indebtedness of the Company or any of its Subsidiaries and appropriate negative
covenants, including, without limitation, negative covenants prohibiting the Corporation, without
the consent of the holders of a majority of aggregate principal amount of all of the Redemption
Notes outstanding, from taking, or permitting any of its Subsidiaries to take, any of the actions
specified in Sections 3(b)(i) — xvi.

          c. Reissuance of Certificate. If fewer than the total number of shares of Series B
Preferred represented by any certificate are redeemed in any installment, a new certificate
representing the number of unredeemed shares of Series B Preferred (other than any Non-Funded
Shares) will be issued to the holder thereof without cost to such holder promptly after surrender
of the certificate representing the redeemed shares of Series B Preferred.

          d. Redeemed or Otherwise Acquired Shares. All rights pertaining to shares of the
Series B Preferred that are redeemed or otherwise acquired by the Corporation and, subject to
Section 5(b), all rights pertaining to shares that are deemed to be Non-Funded Shares,
shall cease, and such shares shall not thereafter be (i) reissued, sold or transferred, (ii)
entitled to any dividends accruing after the date of redemption or acquisition or (iii) deemed to
be issued and outstanding for any purpose whatsoever. The shares of Series B Preferred not redeemed
(other than any Non-Funded Shares) shall remain issued and outstanding and entitled to all the
rights and preferences provided herein.

     (6) Events of Noncompliance.

          a. Definition. An “Event of Noncompliance” shall be deemed to have
occurred if:

     (i) the Corporation shall fail to make any redemption payment required under Section 5
or the equivalent provisions of the other series of Pari Passu Preferred (whether or not
such payment is legally permissible or is prohibited by any agreement to which the
Corporation is subject);

     (ii) (v) the Corporation breaches any of its covenants or agreements contained in
the Preferred Stock Purchase Agreement, which breach has, or is more likely than not to
have, an adverse effect of $100,000 or more in the aggregate on the holders of the Pari
Passu Preferred, (x) such breach does not result directly from action by the Corporation at
express the direction of the Board (including in such direction a majority of the Investor
Directors), (y) the Corporation fails to cure such breach within 30 days of written notice
thereof from any holder of the Pari Passu Preferred and (z) the holders of at least a
majority of the outstanding shares of Pari Passu Preferred after such 30-day period send a
notice of such Event of Noncompliance to the Corporation;

     (iii) (x) any representation or warranty made by the Corporation under the
Preferred Stock Purchase Agreement shall have been untrue or incorrect in any material
respect when made, the result of which has, or is more likely than not to have, an adverse
effect of $100,000 or more on (A) the condition (financial or otherwise), operating results,
business, assets, operations, employee relations or client relations of the Corporation,
taken as a whole (other than to the extent resulting from a change in accounting methods
required by GAAP) or (B) the holders of the Pari Passu Preferred, (y) the Corporation fails
to cure such breach within 30 days of written notice thereof from any holder of the Pari
Passu Preferred and (z) the holders of at least a majority of the outstanding shares of Pari
Passu Preferred send a notice of such Event of Noncompliance to the Corporation;

     (iv) the Corporation shall commence or enter into any bankruptcy,
receivership, liquidation or assignment for the benefit of any creditors;

     (v) the Corporation shall default under one or more indentures, agreements or
other instruments under which any Indebtedness aggregating at least $100,000 of the
Corporation or any of its Subsidiaries is or may be issued, and such default shall continue
for a period of time sufficient to permit the acceleration of the maturity of any
Indebtedness of the Corporation or any of its Subsidiaries outstanding thereunder (which
default has not been cured or waived), other than a default which directly results from
action by the Corporation at the express direction of the Board (including in such direction
a majority of the Investor Directors); or

     (vi) a judgment in excess of $500,000 is rendered against the Corporation and,
within 60 days after entry thereof, such judgment is not discharged or execution thereof
stayed pending appeal, or within 60 days after the expiration of such stay, such judgment

-7-

 

is not discharged.

          b. Consequences of Events of Noncompliance.

     (i) Additional Directors. Upon the occurrence of an Event of Noncompliance and
for so long as such Event of Noncompliance continues, the holders of Pari Passu Preferred and
Conversion Common Shares shall be entitled to appoint such number of additional Investor Directors
to the Board (selected by the holders of a majority of the Pari Passu Preferred and Conversion
Common Shares) such that the holders of Pari Passu Preferred and Conversion Common Shares have
appointed a majority of the Board. Upon notice from the holders of a majority of the outstanding
Pari Passu Preferred and Conversion Common Shares, voting as a single class on a Common Equivalent
Basis, then outstanding that they intend to exercise their rights under this Section
6(b)(i), the Corporation shall immediately take whatever action is necessary so as to
effectuate this Section 6(b)(i), including, without limitation, increasing the size of the
Board and electing such additional Investor Directors.

     (ii) Increased Dividend Rate. Upon the occurrence of an Event of Noncompliance
and for so long as such Event of Noncompliance continues, the dividend rate on the Series B
Preferred set forth in Section 2(a) shall be increased from 5% to 7% per annum.

     (iii) Redemption of Pari Passu Preferred. Upon the occurrence of an Event of
Noncompliance and for so long as such Event of Noncompliance continues, the holders of a majority
of the shares of Pari Passu Preferred then outstanding may require by notice given to the
Corporation that all of the shares of Pari Passu Preferred be immediately (and in no event later
than five business days after such request) redeemed by the Corporation at a price per share of
Pari Passu Preferred equal to the their respective Liquidation Values plus a rate of return on such
amount (after taking into account all dividends paid by the Corporation pursuant to Section
2(a)) equal to 7% per annum, compounded annually.

     (iv) Inadequate Funds. If the funds of the Corporation legally available for
redemption of Pari Passu Preferred pursuant to Section 6(b)(iii) are insufficient to redeem
all shares of Pari Passu Preferred, the provisions of Sections 5(b) and (c) shall apply to
the same extent as if such provisions were set forth in their entirety in this Section
6(b)(iv).

     (v) Reissuance of Certificate. If fewer than the total number of shares of
Series B Preferred or Conversion Common Shares represented by any certificate are redeemed in any
installment pursuant to Section 6(b)(iv), a new certificate representing the number of
unredeemed shares of such Series B Preferred or Conversion Common Shares, as the case may be, will
be issued to the holder thereof without cost to such holder promptly after surrender of the
certificate representing the redeemed shares of Series B Preferred or Conversion Common Shares, as
the case may be.

          c. No Limitation of Rights. If any Event of Noncompliance exists, each

-8-

 

holder of Series B Preferred shall also have any other rights that such holder is entitled to under
any contract or agreement at any time and any other rights that such holder may have pursuant to
applicable law.

          d. Survival of Representations and Warranties. For the purposes of
determining an Event of Noncompliance, the representations and warranties referred to in
Section 6(a)(iii) shall have the respective survival periods set forth in the
Preferred Stock Purchase Agreement.

     (7) Conversion.

     a. Conversion Procedure.

     (i) At any time and from time to time, a holder of Series B Preferred shall have
the right to convert all or any portion of its shares of Series B Preferred into the number
of shares of Common computed by dividing (x) the aggregate Series B Liquidation
Value of the shares of Series B Preferred to be converted by (y) the Series B Conversion
Price then in effect.

     (ii) All shares of Series B Preferred shall automatically convert into Common
(pursuant to the computation set forth in Section 7(a)(i)) upon (A) the affirmative
written consent of the holders of at least a majority of the outstanding shares of Pari
Passu Preferred or (B) receipt by the Corporation of total gross offering proceeds of at
least $50,000,000 from the sale of shares of Common pursuant to the Corporation’s firm
commitment underwritten Public Offering of the Common, at a gross price per share not less
than $16 (as adjusted to reflect stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences) (a “Qualified IPO”).

     (iii) Each conversion of Series B Preferred shall be deemed to have been effected
as of the close of business on the earlier of (A) the date specified in the affirmative
written consent of the holders of at least a majority of the outstanding shares of Series B
Preferred or (B) the date immediately prior to the closing date of a Qualified IPO (any such
date referred to in clause (A) or (B) being referred to as a “Conversion
Date”). At the time
any such conversion has been effected, the rights of the holder of the shares of Series B
Preferred converted as a holder of Series B Preferred shall cease and the Person or Persons
in whose name or names any certificate or certificates for shares of Common are to be issued
upon such conversion shall be deemed to have become the holder or holders of record of the
shares of Common represented thereby.

     (iv) As soon as possible after a conversion has been effected (but in any event
within five (5) business days in the case of subparagraph (A) below), the Corporation shall
deliver to the converting holder:

               (A) certificates representing the number of shares of Common issuable by reason of
such conversion in such name or names and such denomination or denominations as the
converting holder has specified; and

               (B) a certificate representing any shares of Series B Preferred

-9-

 

which were represented by the certificate or certificates delivered to the Corporation in
connection with such conversion but which were not converted.

     (v) The issuance of certificates for shares of Common upon conversion of Series B
Preferred shall be made without charge to the holders of such Series B Preferred or Common for any
issuance tax in respect thereof or other cost incurred by the Corporation in connection with such
conversion and the related issuance of shares of Common. Upon conversion of each share of Series B
Preferred, the Corporation shall take all such actions as are necessary in order to insure that the
Common issuable with respect to such conversion shall be validly issued, fully paid and
nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the
issuance thereof.

     (vi) The Corporation shall not close its books against the transfer of Series B Preferred
or of Common issued or issuable upon conversion of Series B Preferred in any manner that interferes
with the timely conversion of Series B Preferred. The Corporation shall assist and cooperate with
any holder of shares of Series B Preferred required to make any governmental filings or obtain any
governmental approval prior to or in connection with any conversion of shares hereunder (including,
without limitation, making any filings required to be made by the Corporation).

     (vii) The Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common, solely for the purpose of issuance upon the conversion of shares of
the Series B Preferred, such number of shares of Common as are issuable upon the conversion of all
outstanding Series B Preferred. All shares of Common which are so issuable shall, when issued, be
duly and validly issued, fully paid and nonassessable and free from all taxes, liens, charges and
encumbrances. The Corporation shall take all such actions as may be necessary to insure that all
such shares of Common may be so issued without violation of any applicable law or governmental
regulation or any requirements of any domestic securities exchange upon which shares of Common
may be listed (except for official notice of issuance which shall be delivered immediately by the
Corporation upon each such issuance). The Corporation shall not take any action that would cause
the number of authorized but unissued shares of Common to be less than the number of such shares
required to be reserved hereunder for issuance upon conversion of the Series B Preferred.

     (viii) If any fractional interest in a share of Common would, except for the provisions of
this subparagraph, be delivered upon any conversion of the Series B Preferred, the Corporation, in
lieu of delivering the fractional share therefor, may pay an amount to the holder thereof equal to
the fair market value per share of Common as of the date of conversion as determined in good faith
by the Board, including a majority of the Investor Directors, multiplied by such fractional
interest; provided, however, that in the case of a Qualified IPO the fair market value per share of
Common shall be the gross price per share of Common in such Qualified IPO. The determination as to
whether or not to make any cash payment in lieu of the issuance of fractional shares shall be based
upon the total number of shares of Series B Preferred being converted at any one time by the holder
thereof, not upon each share of Series B Preferred being converted.

-10-

 

     (ix) All certificates representing shares of Series B Preferred which are required to be
surrendered for conversion in accordance with the provisions hereof shall, from and after the
Conversion Date, be deemed to have been retired and cancelled, and ‘ the shares of Series B
Preferred converted pursuant to this Section 7 represented thereby shall, from and after
the Conversion Date, be deemed to have been converted into Common for all purposes, notwithstanding
any failure of the holder or holders thereof to surrender such certificates on or prior to the
Conversion Date. The Corporation from time to time may take such appropriate corporate action as
may be necessary to reduce the authorized number of shares of the Series B Preferred Stock
accordingly.

     b. Conversion Price.

     (i) The initial Series B Conversion Price shall be $3.00 per share of Common (subject
to adjustment in the event of stock splits, stock dividends, stock combinations, recapitalizations
and like occurrences). In order to prevent dilution of the conversion rights granted under this
Section 7, the Series B Conversion Price shall be subject to adjustment from time to time
pursuant to this Section 7(b).

     (ii) If and whenever on or after the Series B Original Issuance Date the Corporation
issues or sells or, in accordance with this Section 7, is deemed to have issued or sold,
any shares of its Common for a consideration per share less than the Series B Conversion Price in
effect immediately prior to the time of such issuance, then immediately upon such issuance or sale
or deemed issuance or sale the Series B Conversion Price shall be reduced to the conversion price
determined by dividing (A) the sum of (1) the product derived by multiplying the Series B
Conversion Price in effect immediately prior to such issuance or sale by the number of shares of
Common Deemed Outstanding immediately prior to such issuance or sale, plus (2) the consideration,
if any, received by the Corporation upon such issuance or sale, by (B) the number of shares of
Common Deemed Outstanding immediately after such issue or sale.

     (iii) Notwithstanding the foregoing, there shall be no adjustment in the Series B
Conversion Price as a result of any issuance or sale (or deemed issuance or sale) of:

     (A) shares of Common issued upon conversion of the Pari Passu Preferred;

     (B) shares of Common issued upon the exercise of the Warrants;

     (C) shares of Common issued upon the exercise of Options or other Convertible
Securities outstanding as of the First Closing Date;

     (D) securities issued pursuant to a Board-approved (including at least one of
the Investor Directors) bona fide acquisition of an entity by merger, purchase of
substantially all of the assets or other reorganization;

     (E) shares of Common issued to Catalyst pursuant to the Options granted
under the Catalyst Letter Agreements;

-11-

 

     (F) shares of Common or other securities issued as a dividend
or distribution on, or in connection with a split of or recapitalization
of, any of the capital stock of the Corporation;

     (G) up to an aggregate of 250,000 shares of Common reserved for
issuance per year pursuant to the Option Plan (subject to adjustment in the
event of stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences) and shares of Common reserved for
issuance pursuant to the Option Plan in lieu of the repayment of certain
salary deferrals as approved by a majority of the Board (including at least
one of the Investor Directors), which foregoing shares may be subject to
Options or restricted stock awards granted under the Option Plan; provided
that any Options that expire or terminate unexercised or any restricted
stock awards that are repurchased by the Corporation pursuant to the terms
of such award shall not be counted toward the maximum number set forth in
this subparagraph (G) unless and until such shares are subject to new
restricted stock awards (or new Options) pursuant to the terms of the
Option Plan;

     (H) shares of Common issued or issuable (including options to
acquire such shares of Common) .to suppliers or third-party service
providers in connection with the provision of goods or services pursuant to
transactions in the ordinary course of business and approved by a majority
of the Board, including at least one of the Investor Directors;

     (I) shares of Common issued or issuable in connection with
bona-fide sponsored research, collaboration, technology license, development,
OEM, marketing or other similar agreements or strategic partnerships or joint
ventures entered into in the ordinary course of business and approved by a
majority of the Board, including at least one of the Investor Directors (and
by at least a majority of the shares of Pari Passu Preferred and Conversion
Common Shares, voting as a single class on a Common Equivalent Basis, then
outstanding, if required pursuant to Section 3(c));

     (J) securities issued in connection with a Qualified IPO;
or

     (K) Permitted Issuances;

provided that the aggregate number of shares of Common issued or issuable pursuant to
clauses (H) and (I) above shall not exceed 100,000 in any twelve-month period;

          c. Effect on Conversion Price of Certain Events. For purposes of determining
the Series B Conversion Price under Section 7, the following shall be applicable:

     (i) Issuance of Options. If the Corporation in any manner grants, issues or
sells any Options (other than any Options permitted by Section 7(b)(iii)) and the price per
share for which Common is issuable upon the exercise of such Options, or upon

-12-

 

conversion or exchange of any Convertible Securities issuable upon exercise of such Options, is
less than the Series B Conversion Price in effect immediately prior to the time of the granting,
issuance or sale of such Options, then the total maximum number of shares of Common issuable upon
the exercise of such Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities issuable upon the exercise of such Options shall be deemed to be outstanding
and to have been issued and sold by the Corporation at the time of the granting, issuance or sale
of such Options for such price per share. For purposes of this paragraph, the “price per share for
which Common is issuable” shall be determined by dividing (A) the sum of (1) the total
amount, if any, received or receivable by the Corporation as consideration for the granting,
issuance or sale of such Options, plus (2) the minimum aggregate amount of additional
consideration payable to the Corporation upon exercise of all such Options, plus (3) in the
case of such Options which relate to Convertible Securities, the minimum aggregate amount of
additional consideration, if any, payable to the Corporation upon the issuance or sale of such
Convertible Securities and the conversion or exchange thereof, by (B) the total maximum number of
shares of Common 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. No further adjustment
of the Conversion Price shall be made when Convertible Securities are actually issued upon the
exercise of such Options or when Common is actually issued upon the exercise of such Options or the
conversion or exchange of such Convertible Securities.

     (ii) Issuance of Convertible Securities. If the Corporation in any manner issues
or sells any Convertible Securities and the price per share for which Common is issuable upon
conversion or exchange thereof is less than the Series B Conversion Price in effect immediately
prior to the time of such issuance or sale, then the maximum number of shares of Common issuable
upon conversion or exchange of such Convertible Securities shall be deemed to be outstanding and to
have been issued and sold by the Corporation at the time of the issuance or sale of such
Convertible Securities for such price per share. For the purposes of this paragraph, the “price per
share for which Common is issuable” shall be determined by dividing (A) the sum of (1) the
total amount received or receivable by the Corporation as consideration for the issue or sale of
such Convertible Securities, plus (2) the minimum aggregate amount of additional consideration, if
any, payable to the Corporation upon the conversion or exchange thereof, by (B) the total maximum
number of shares of Common issuable upon the conversion or exchange of all such Convertible
Securities. No further adjustment of the Series B Conversion Price shall be made when Common is
actually issued upon the conversion or exchange of such Convertible Securities, and if any such
issuance or sale of such Convertible Securities is made upon exercise of any Options for which
adjustments of the Series B Conversion Price had been or are to be made pursuant to other
provisions of this Section 7, no further adjustment of the conversion price shall be made by reason
of such issue or sale.

     (iii) Change in Option Price or Conversion Rate. If the purchase price provided
for in any Options, the additional consideration, if any, payable upon the conversion or exchange
of any Convertible Securities or the rate at which any Convertible Securities are convertible into
or exchangeable for Common changes at any

-13-

 

time, the Series B Conversion Price in effect at the time of such change shall be immediately
adjusted to the Series B Conversion Price that 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; provided, that, if such adjustment of the Series B Conversion Price would result in
an increase in the Series B Conversion Price then in effect, the Corporation will promptly give all
holders of Series B Preferred written notice of such increase. For purposes of this Section
7(c)(iii), if the terms of any Option or Convertible Security that was outstanding as of the
Series B Original Issuance Date are changed in the manner described in the immediately preceding
sentence, then such Option or Convertible Security and the Common deemed issuable upon exercise,
conversion or exchange thereof shall be deemed to have been issued as of the date of such change;
provided, that, no such change shall at any time cause the Series B Conversion Price hereunder to
be increased.

     (iv)
Treatment of Expired Options and Unexercised Convertible
Securities. Upon the expiration of any Option or the termination of any right to convert or exchange any Convertible
Security without the exercise of any such Option or right, the Series B Conversion Price then in
effect hereunder shall be adjusted immediately to the Series B Conversion Price that would have
been in effect at the time of such expiration or termination had such Option or Convertible
Security, to the extent outstanding immediately prior to such expiration or termination, never been
issued; provided, that, if such expiration or termination would result in an increase in the Series
B Conversion Price then in effect, the Corporation will promptly give all holders of Series B
Preferred written notice of such increase. For purposes of this Section 7(c)(iv), the
expiration or termination of any Option or Convertible Security that was outstanding as of the
Series B Original Issuance Date shall not cause the Series B Conversion Price hereunder to be
adjusted unless, and only to the extent that, a change in the terms of such Option or Convertible
Security caused it to be deemed to have been issued after the Series B Original Issuance Date.

     (v)
Calculation of Consideration Received. If any Common, Option or Convertible
Security is issued or sold or deemed to have been issued or sold for cash, the consideration
received therefor shall be deemed to be the amount received by the Corporation therefor (net of
discounts, commissions and related expenses). If any Common, Option or Convertible Security is
issued or sold for a consideration other than cash, the amount of the consideration other than cash
received by the Corporation shall be the fair market value of such consideration as determined in
good faith by the Board. If any Common, Option or Convertible Security is issued to the owners of
the non-surviving entity in connection with any merger in which the Corporation is the surviving
corporation, the amount of consideration therefor shall be deemed to be the fair value of such
portion of the net assets and business of the non-surviving entity as is attributable to such
Common, Option or Convertible Security, as the case may be. The fair value of any consideration
other than cash and securities shall be the fair market value as determined in good faith by the
Board.

     (vi)
Integrated Transactions. In case any Option is issued in connection with

-14-

 

the issuance or sale of other securities of the Corporation, together comprising one integrated
transaction in which no specific exercise price is allocated to such Option by the parties thereto,
the Option shall be deemed to have been issued at an exercise price of $0.01.

     (vii) Treasury Shares. The number of shares of Common outstanding at any given time
shall not include shares owned or held by or for the account of the Corporation, and the
disposition of any shares so owned or held shall be considered an issuance or sale of such shares.

     (viii) Record Date. If the Corporation takes a record of the holders of Common for
the purpose of entitling them (A) to receive a dividend or other distribution payable in Common,
Options or in Convertible Securities or (B) to subscribe for or purchase Common, Options or
Convertible Securities, then such record date shall be deemed to be the date of the issue or sale
of the shares of Common deemed to have been issued or sold upon the declaration of such dividend or
upon the making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

     (ix) Subdivisions or Combinations of Common. If the Corporation at any time
subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes
of its outstanding shares of Common into a greater number of shares, the Series B Conversion Price
in effect immediately prior to such subdivision shall be reduced proportionately, and if the
Corporation at any time combines (by reverse stock split or otherwise) one or more classes of its
outstanding shares of Common into a smaller number of shares, the Series B Conversion Price in
effect immediately prior to such combination shall be increased proportionately.

     (x)
Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or
substantially all of the Corporation’s assets or other transaction, in each case which is effected
in such a manner that the holders of Common are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in exchange for Common, is
referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the
Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the
holders of a majority of the Series B Preferred then outstanding) to insure that each of the
holders of Series B Preferred shall thereafter have the right to acquire and receive, in lieu of or
in addition to (as the case may be) the shares of Common immediately theretofore acquirable and
receivable upon the conversion of such holder’s Series B Preferred, such shares of stock,
securities or assets as such holder would have received in connection with such Organic Change if
such holder had converted its Series B Preferred immediately prior to such Organic Change. In each
such case, the Corporation shall also make appropriate provisions (in form and substance reasonably
satisfactory to the holders of a majority of the Series B Preferred then outstanding) to insure
that the provisions of this Section 7(c) shall thereafter be applicable to the securities
issued in exchange for the Series B Preferred (including, in the case of any such consolidation,
merger or sale in which the successor entity or purchasing entity is other than the Corporation and
the value for the

-15-

 

Common reflected by the terms of such consolidation, merger or sale is less than the Series
B Conversion Price in effect immediately prior to such consolidation, merger or sale, an
immediate adjustment of the Series B Conversion Price to the value for the Common so
reflected and a corresponding immediate adjustment in the number of shares of Common
acquirable and receivable upon conversion of Series B Preferred). The Corporation shall not
effect any such consolidation, merger or sale, unless prior to the consummation thereof,
the successor entity (if other than the Corporation) resulting from consolidation or merger
or the entity purchasing such assets assumes by written instrument (in form and substance
satisfactory to the holders of a majority of the Series B Preferred then outstanding) the
obligation to deliver to each such holder such shares of stock, securities or assets as, in
accordance with the foregoing provisions, such holder may be entitled to acquire.

     (xi) Certain Other Events. If any event occurs of the type contemplated
by the provisions of this Section 7 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation rights,
phantom stock rights or other rights with equity features), then the Board shall make an
appropriate adjustment in the Series B Conversion Price so as to protect the rights of the
holders of Series B Preferred; provided, that, no such adjustment shall increase the Series
B Conversion Price as otherwise determined pursuant to this Section 7 or decrease
the number of shares of Common issuable upon conversion of each share of Series B
Preferred.

     d. Notices.

     (i) Immediately upon any adjustment of the Series B Conversion Price, the
Corporation shall give written notice thereof to all holders of Series B Preferred, setting
forth in reasonable detail and certifying the calculation of such adjustment.

     (ii) The Corporation shall give written notice to all holders of Series B
Preferred at least 10 days prior to the date on which the Corporation closes its books or

     (ix) except as provided in the current Budget, create, incur, assume or suffer to
exist any Indebtedness;

     (x) create, incur, assume or suffer to exist any Liens other than (A) Permitted

whole (each, an “Acquisition”), other than Acquisitions the aggregate value of which (after
taking into account the assumption of any Indebtedness or other liabilities in connection
therewith) do not exceed $300,000 in any twelve-month period, measured after giving effect
to any purchase price adjustments relating thereto;

     (xii) become subject to (including, without limitation, by way of amendment to or

     (xiii) except as provided in the current Budget, make or commit to make capital

          d.

any shares of Pari Passu Preferred or Conversion Common Shares remain outstanding, the holders of
the Pari Passu Preferred and Conversion Common Shares, voting together as a single class on a Common
Equivalent Basis, shall be entitled to elect two (2) members of the Board at each meeting or
pursuant to each consent of the Corporation’s stockholders for the election of directors, and to
remove from office any such director and to fill any vacancy caused by the resignation, death or
removal of any such director.

     (4) Liquidation, Dissolution, etc.

          a. Significant Event. Upon any liquidation, Fundamental Change, Change in
Ownership, dissolution or winding up of the Corporation (whether voluntary or involuntary) (each, a
“Significant Event”):

     (i) Each holder of Series C Preferred shall be entitled to receive, prior and
in preference to any distribution or payment made upon any Series C Junior Securities, an
amount equal to (i) the aggregate Series C Liquidation Value of all shares of Series C
Preferred held by such holder plus (ii) all accrued and unpaid dividends on such shares of
Series C Preferred. If, upon any Significant Event, the Corporation’s assets to be
distributed among the holders of the Pari Passu Preferred are insufficient to permit
payment to such holders of the aggregate amount to which they are entitled to be paid under
this Section 4(a)(i) and the equivalent provisions of the other series of Pari
Passu Preferred, then the entire assets available to be distributed to the Corporation’s
stockholders shall be distributed pro rata among such holders of the Pari Passu Preferred
based upon the aggregate Liquidation Value (plus all accrued and unpaid dividends) of the
shares of Pari Passu Preferred held by each such holder.

     (ii) After payment to the holders of the Series C Preferred of the amounts set
forth in the first sentence of Section 4(a)(i), the entire remaining assets and funds of
the Corporation legally available for distribution, if any, shall be distributed pro rata
among the holders of the Common and the holders of the Pari Passu Preferred (on a Common
Equivalent Basis).

-4-

 

          b. Form of Consideration. Whenever the distribution provided for in this Section
4 shall be payable in a form other than securities or cash, the value of such distribution
shall be the fair market value as determined in good faith by the Board, including a majority of
the Investor Directors.

          c. Distribution upon Change in Ownership. Upon any Significant Event effected as a
result of a Change in Ownership, any proceeds received by stockholders of the Corporation other,
than holders of Pari Passu Preferred in accordance with the terms of
such Pari Passu Preferred
(including, without limitation, any amounts received by any stockholders in respect of any
employment, non-competition, consulting or other similar agreement entered into in connection with
such Change in Ownership that, in the case of employment or consulting agreements, provide for
payments to such stockholder that are in excess of the compensation payable to such stockholder
prior to such Change in Ownership (other than, in the case of employment, for increases in annual
compensation not in excess of 20% of the annual compensation payable to such stockholder in the
last completed fiscal year prior to such Change in Ownership)) shall be construed as being received
by the Corporation and thereafter distributed to the holders of the
Pari Passu Preferred and Common
in accordance with Section 4(a)(ii).

	 	 	(5)	 	Redemptions.

          a. Redemption at the Option of Holders. At any time on or after March 14,
2012, upon the request of the holders of at least a majority of the then outstanding shares of
Series C Preferred, each of the holders of the then outstanding Series C Preferred shall have the
right (a “Redemption Right”) to require the Corporation to redeem all or any of their shares of
Series C Preferred at a price per share equal to the Series C Liquidation Value plus a rate of
return on such amount (after taking into account all dividends paid by the Corporation pursuant to
Section 2(a)) equal to 7% per annum, compounded annually. Any holder of Series C Preferred
may exercise his, her or its Redemption Right by delivering to the Corporation a Redemption Notice
on or after March 14, 2012, provided that holders of at least a majority of the then outstanding
shares of Pari Passu Preferred have requested a redemption pursuant to this Section 5 (a)
and the equivalent provisions of the other series of Pari Passu Preferred. Within ten (10) days
after the date of a Redemption Notice delivered by any holder of Series C Preferred, the
Corporation shall notify all other holders of Pari Passu Preferred that the Redemption Right has
been exercised, and each other holder of Pari Passu Preferred shall have the right, exercisable by
written notice delivered to the Corporation within thirty (30) days after receipt of such notice
from the Corporation, to request that all or a portion of such other holder’s shares of Pari Passu
Preferred be redeemed on the Redemption Date together with the shares of Series C Preferred of the
holder who delivered the Redemption Notice. The Corporation shall be obligated to redeem the total
number of shares of Series C Preferred requested to be redeemed in accordance herewith on the
Redemption Date. For each share of Series C Preferred which is to be redeemed on a particular
Redemption Date in accordance with this Section 5(a), the Corporation shall be obligated on the
date specified for redemption thereof in the written notice with respect thereto, to pay to the
holder thereof (upon surrender by such holder at the Corporation’s principal office of the
certificate representing such share) such amount specified in this Section 5(a) in immediately
available funds.

          b. Inadequate Funds; Redemption Notes. If the funds of the Corporation

-5-

 

legally available for redemption of Series C Preferred on any Redemption Date are insufficient to
redeem the total number of shares of Series A Preferred and all other shares of Pari Passu
Preferred to be redeemed on such date: (i) those funds which are legally available shall be used to
redeem the maximum possible number of shares of Pari Passu Preferred ratably among the holders of
such shares to be redeemed based upon the aggregate amount to which they are entitled to be paid
under this Section 5 and the equivalent provisions of the other series of Pari Passu
Preferred; and (ii) with respect to those shares of Pari Passu Preferred requested to be redeemed
but for which funds are not legally available (the “Non-Funded Shares”), the Corporation shall
issue and deliver to each holder of Non-Funded Shares a promissory note (each a “Redemption Note”).
Each Redemption Note shall be payable one year from date of issuance and shall bear interest at the
rate of 8% per annum, compounded quarterly, and shall have an aggregate principal amount per
Non-Funded Share equal to the Series C Liquidation Value plus a rate of return on such amount
(after taking into account all dividends paid by the Corporation pursuant to Section 2(a))
equal to 7% per annum, compounded annually. A Redemption Note may be prepaid by the Company at any
time without penalty. The issuance of Redemption Notes shall be made without charge to the holders
of the Non-Funded Shares receiving such Redemption Notes for any issuance tax in respect thereof or
other cost incurred by the Corporation in connection with the issuance thereof, and the Corporation
shall pay the fees and expenses of each holder of Non-Funded Shares in connection with the issuance
of Redemption Notes, including reasonable attorney’s fees and expense. Subject to the terms of any
then existing senior debt or credit facility, the terms and documentation relating to each
Redemption Note shall provide that the debt obligation evidenced thereby shall at all times be pari
passu with the most senior debt or credit facility of the Corporation outstanding at any time
during the term of the Redemption Note. Each Redemption Note shall also contain customary terms and
conditions, including, without limitation, a cross-acceleration provision with respect to any
amount of Indebtedness of the Company or any of its Subsidiaries and appropriate negative
covenants, including, without limitation, negative covenants prohibiting the Corporation, without
the consent of the holders of a majority of aggregate principal amount of all of the Redemption
Notes outstanding, from taking, or permitting any of its Subsidiaries to take, any of the actions
specified in Sections 3(b)(i) — xvi.

          c. Reissuance of Certificate. If fewer than the total number of shares of Series C
Preferred represented by any certificate are redeemed in any installment, a new certificate
representing the number of unredeemed shares of Series C Preferred (other than any Non-Funded
Shares) will be issued to the holder thereof without cost to such holder promptly after surrender
of the certificate representing the redeemed shares of Series C Preferred.

          d. Redeemed or Otherwise_Acquired Shares. All rights pertaining to shares of the
Series C Preferred that are redeemed or otherwise acquired by the Corporation and, subject to
Section 5(b), all rights pertaining to shares that are deemed to be Non-Funded Shares,
shall cease, and such shares shall not thereafter be (i) reissued, sold or transferred, (ii)
entitled to any dividends accruing after the date of redemption or acquisition or (iii) deemed to
be issued and outstanding for any purpose whatsoever. The shares of Series C Preferred not redeemed
(other than any Non-Funded Shares) shall remain issued and outstanding and entitled to all the
rights and preferences provided herein.

     (6) Events of Noncompliance.

          a. Definition. An “Event of Noncompliance” shall be deemed to have
occurred if:

     (i) the Corporation shall fail to make any redemption payment required under Section 5
or the equivalent provisions of the other series of Pari Passu Preferred (whether or not
such payment is legally permissible or is prohibited by any agreement to which the
Corporation is subject);

     (ii) (v) the Corporation breaches any of its covenants or agreements contained in
the Preferred Stock Purchase Agreement, which breach has, or is more likely than not to
have, an adverse effect of $100,000 or more in the aggregate on the holders of the Pari
Passu Preferred, (x) such breach does not result directly from action by the Corporation at
express the direction of the Board (including in such direction a majority of the Investor
Directors), (y) the Corporation fails to cure such breach within 30 days of written notice
thereof from any holder of the Pari Passu Preferred and (z) the holders of at least a
majority of the outstanding shares of Pari Passu Preferred after such 30-day period send a
notice of such Event of Noncompliance to the Corporation;

     (iii) (x) any representation or warranty made by the Corporation under the
Preferred Stock Purchase Agreement shall have been untrue or incorrect in any material
respect when made, the result of which has, or is more likely than not to have, an adverse
effect of $100,000 or more on (A) the condition (financial or otherwise), operating results,
business, assets, operations, employee relations or client relations of the Corporation,
taken as a whole (other than to the extent resulting from a change in accounting methods
required by GAAP) or (B) the holders of the Pari Passu Preferred, (y) the Corporation fails
to cure such breach within 30 days of written notice thereof from any holder of the Pari
Passu Preferred and (z) the holders of at least a majority of the outstanding shares of Pari
Passu Preferred send a notice of such Event of Noncompliance to the Corporation;

     (iv) the Corporation shall commence or enter into any bankruptcy,
receivership, liquidation or assignment for the benefit of any creditors;

     (v) the Corporation shall default under one or more indentures, agreements or
other instruments under which any Indebtedness aggregating at least $100,000 of the
Corporation or any of its Subsidiaries is or may be issued, and such default shall continue
for a period of time sufficient to permit the acceleration of the maturity of any
Indebtedness of the Corporation or any of its Subsidiaries outstanding thereunder (which
default has not been cured or waived), other than a default which directly results from
action by the Corporation at the express direction of the Board (including in such direction
a majority of the Investor Directors); or

     (vi) a judgment in excess of $500,000 is rendered against the Corporation and, within 60
days after entry thereof, such judgment is not discharged or execution thereof stayed pending
appeal, or within 60 days after the expiration of such stay, such judgment

-7-

 

is not discharged.

          b. Consequences of Events of Noncompliance.

     (i) Additional Directors. Upon the occurrence of an Event of Noncompliance and for so
long as such Event of Noncompliance continues, the holders of Pari Passu Preferred and Conversion
Common Shares shall be entitled to appoint such number of additional Investor Directors to the
Board (selected by the holders of a majority of the Pari Passu Preferred and Conversion Common
Shares) such that the holders of Pari Passu Preferred and Conversion Common Shares have appointed a
majority of the Board. Upon notice from the holders of a majority of the outstanding Pari Passu
Preferred and Conversion Common Shares, voting as a single class on a Common Equivalent Basis, then
outstanding that they intend to exercise their rights under this
Section 6(b)(i), the
Corporation shall immediately take whatever action is necessary so as to effectuate this Section
6(b)(i), including, without limitation, increasing the size of the Board and electing such
additional Investor Directors.

     (ii) Increased Dividend Rate. Upon the occurrence of an Event of Noncompliance
and for so long as such Event of Noncompliance continues, the dividend rate on the Series C
Preferred set forth in Section 2(a) shall be increased from 5% to 7% per annum.

     (iii)
Redemption of Pari Passu Preferred. Upon the occurrence of an Event of
Noncompliance and for so long as such Event of Noncompliance continues, the holders of a majority
of the shares of Pari Passu Preferred then outstanding may require by notice given to the
Corporation that all of the shares of Pari Passu Preferred be immediately (and in no event later
than five business days after such request) redeemed by the Corporation at a price per share of
Pari Passu Preferred equal to the their respective Liquidation Values plus a rate of return on such
amount (after taking into account all dividends paid by the Corporation pursuant to Section 2fa))
equal to 7% per annum, compounded annually.

     (iv) Inadequate Funds. If the funds of the Corporation legally available for
redemption of Pari Passu Preferred pursuant to Section 6(b)(Viii) are insufficient to
redeem all shares of Pari Passu Preferred, the provisions of Sections 5(b) and (c) shall
apply to the same extent as if such provisions were set forth in their entirety in this Section
6(b)(iv).

     (v) Reissuance of Certificate. If fewer than the total number of shares of
Series C Preferred or Conversion Common Shares represented by any certificate are redeemed in any
installment pursuant to Section 6(b)(iv), a new certificate representing the number of
unredeemed shares of such Series C Preferred or Conversion Common Shares, as the case may be, will
be issued to the holder thereof without cost to such holder promptly after surrender of the
certificate representing the redeemed shares of Series C Preferred or Conversion Common Shares, as
the case may be.

          c. No Limitation of Rights. If any Event of Noncompliance exists, each

-8-

 

holder of Series C Preferred shall also have any other rights that such holder is entitled to under
any contract or agreement at any time and any other rights that such holder may have pursuant to
applicable law.

          d. Survival of Representations and Warranties. For the purposes of
determining an Event of Noncompliance, the representations and warranties referred to in
Section 6(a)(iii) shall have the respective survival periods set forth in the
Preferred Stock Purchase Agreement.

     (7) Conversion.

          a. Conversion Procedure.

     (i) At any time and from time to time, a holder of Series C Preferred shall have
the right to convert all or any portion of its shares of Series C Preferred into the number
of shares of Common computed by dividing (x) the aggregate Series C Liquidation Value of the
shares of Series C Preferred to be converted by (y) the Series C Conversion Price then in
effect.

     (ii) All shares of Series C Preferred shall automatically convert into Common
(pursuant to the computation set forth in Section 7(a)(i)) upon (A) the affirmative
written consent of the holders of at least a majority of the outstanding shares of Pari Passu
Preferred or (B) receipt by the Corporation of total gross offering proceeds of at least
$50,000,000 from the sale of shares of Common pursuant to the Corporation’s firm commitment
underwritten Public Offering of the Common, at a gross price per share not less than $16 (as
adjusted to reflect stock splits, stock dividends, stock combinations, recapitalizations and
like occurrences) (a “Qualified IPO”).

     (iii) Each conversion of Series C Preferred shall be deemed to have been effected
as of the close of business on the earlier of (A) the date specified in the affirmative
written consent of the holders of at least a majority of the outstanding shares of Series C
Preferred or (B) the date immediately prior to the closing date of a Qualified IPO (any such
date referred to in clause (A) or (B) being referred to as
a “Conversion Date”). At the time
any such conversion has been effected, the rights of the holder of the shares of Series C
Preferred converted as a holder of Series C Preferred shall cease and the Person or Persons
in whose name or names any certificate or certificates for shares of Common are to be issued
upon such conversion shall be deemed to have become the holder or holders of record of the
shares of Common represented thereby.

     (iv) As soon as possible after a conversion has been effected (but in any event
within five (5) business days in the case of subparagraph (A) below), the Corporation shall
deliver to the converting holder:

                    (A) certificates representing the number of shares of Common issuable by reason of such
conversion in such name or names and such denomination or denominations as the converting
holder has specified; and

                    (B) a certificate representing any shares of Series C Preferred

-9-

 

which were represented by the certificate or certificates delivered to the Corporation in
connection with such conversion but which were not converted.

     (v) The issuance of certificates for shares of Common upon conversion of Series C
Preferred shall be made without charge to the holders of such Series C Preferred or Common for any
issuance tax in respect thereof or other cost incurred by the Corporation in connection with such
conversion and the related issuance of shares of Common. Upon conversion of each share of Series C
Preferred, the Corporation shall take all such actions as are necessary in order to insure that the
Common issuable with respect to such conversion shall be validly issued, fully paid and
nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the
issuance thereof.

     (vi) The Corporation shall not close its books against the transfer of Series C Preferred
or of Common issued or issuable upon conversion of Series C Preferred in any manner that interferes
with the timely conversion of Series C Preferred. The Corporation shall assist and cooperate with
any holder of shares of Series C Preferred required to make any governmental filings or obtain any
governmental approval prior to or in connection with any conversion of shares hereunder (including,
without limitation, making any filings required to be made by the Corporation).

     (vii) The Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common, solely for the purpose of issuance upon the conversion of shares of
the Series C Preferred, such number of shares of Common as are issuable upon the conversion of all
outstanding Series C Preferred. All shares of Common which are so issuable shall, when issued, be
duly and validly issued, fully paid and nonassessable and free from all taxes, liens, charges and
encumbrances. The Corporation shall take all such actions as may be necessary to insure that all
such shares of Common may be so issued without violation of any applicable law or governmental
regulation or any requirements of any domestic securities exchange upon which shares of Common
may be listed (except for official notice of issuance which shall be delivered immediately by the
Corporation upon each such issuance). The Corporation shall not take any action that would cause
the number of authorized but unissued shares of Common to be less than the number of such shares
required to be reserved hereunder for issuance upon conversion of the Series C Preferred.

     (viii) If any fractional interest in a share of Common would, except for the provisions of
this subparagraph, be delivered upon any conversion of the Series C Preferred, the Corporation, in
lieu of delivering the fractional share therefor, may pay an amount to the holder thereof equal to
the fair market value per share of Common as of the date of conversion as determined in good faith
by the Board, including a majority of the Investor Directors, multiplied by such fractional
interest; provided, however, that in the case of a Qualified IPO the fair market value per share of
Common shall be the gross price per share of Common in such Qualified IPO. The determination as to
whether or not to make any cash payment in lieu of the issuance of fractional shares shall be based
upon the total number of shares of Series C Preferred being converted at any one time by the holder
thereof, not upon each share of Series C Preferred being converted.

-10-

 

     (ix) All certificates representing shares of Series C Preferred which are required
to be surrendered for conversion in accordance with the provisions hereof shall, from and
after the Conversion Date, be deemed to have been retired and cancelled, and the shares of
Series C Preferred converted pursuant to this Section 7 represented thereby shall;
from and after the Conversion Date, be deemed to have been converted into Common for all
purposes, notwithstanding any failure of the holder or holders thereof to surrender such
certificates on or prior to the Conversion Date. The Corporation from time to time may take
such appropriate corporate action as may be necessary to reduce the authorized number of
shares of the Series C Preferred Stock accordingly.

	 	b.	 	Conversion Price.

        
(i) The initial Series C Conversion Price shall be $3.00 per share of Common
(subject to adjustment in the event of stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences). In order to prevent dilution of the conversion
rights granted under this Section 7, the Series C Conversion Price shall be subject
to adjustment from time to time pursuant to this Section 7(b).

        
(ii) If and whenever on or after the Series C Original Issuance Date the
Corporation issues or sells or, in accordance with this Section 7, is deemed to have
issued or sold, any shares of its Common for a consideration per share less than the Series
C Conversion Price in effect immediately prior to the time of such issuance, then
immediately upon such issuance or sale or deemed issuance or sale the Series C Conversion
Price shall be reduced to the conversion price determined by dividing (A) the sum of (1) the
product derived by multiplying the Series C Conversion Price in effect immediately prior to
such issuance or sale by the number of shares of Common Deemed Outstanding immediately prior
to such issuance or sale, plus (2) the consideration, if any, received by the Corporation
upon such issuance or sale, by (B) the number of shares of Common Deemed Outstanding
immediately after such issue or sale.

         (iii) Notwithstanding the foregoing, there shall be no adjustment in the Series C
Conversion Price as a result of any issuance or sale (or deemed issuance or sale) of:

        (A) shares of Common issued upon conversion of the Pari Passu
Preferred;

        (B) shares of Common issued upon the exercise of the Warrants;

        (C) shares of Common issued upon the exercise of Options or other
Convertible Securities outstanding as of the First Closing Date;

        (D) securities issued pursuant to a Board-approved (including at least
one of the Investor Directors) bona fide acquisition of an entity by merger,
purchase of substantially all of the assets or other reorganization;

        (E) shares of Common issued to Catalyst pursuant to the
Options granted under the Catalyst Letter Agreements;

-11-

 

          (F) shares of Common or other securities issued as a dividend or
distribution on, or in connection with a split of or recapitalization of,
any of the capital stock of the Corporation;

          (G) up to an aggregate of 250,000 shares of Common reserved for
issuance per year pursuant to the Option Plan (subject to adjustment in the
event of stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences) and shares of Common reserved for
issuance pursuant to the Option Plan in lieu of the repayment of certain
salary deferrals as approved by a majority of the Board (including at least
one of the Investor Directors), which foregoing shares may be subject to
Options or restricted stock awards granted under the Option Plan; provided
that any Options that expire or terminate unexercised or any restricted
stock awards that are repurchased by the Corporation pursuant to the terms
of such award shall not be counted toward the maximum number set forth in
this subparagraph (G) unless and until such shares are subject to new
restricted stock awards (or new Options) pursuant to the terms of the Option
Plan;

          (H) shares of Common issued or issuable (including options to
acquire such shares of Common) to suppliers or third-party service providers
in connection with the provision of goods or services pursuant to
transactions in the ordinary course of business and approved by a majority
of the Board, including at least one of the Investor Directors;

          (I) shares of Common issued or issuable in connection with
bona-fide sponsored research, collaboration, technology license,
development, OEM, marketing or other similar agreements or strategic
partnerships or joint ventures entered into in the ordinary course of
business and approved by a majority of the Board, including at least one of
the Investor Directors (and by at least a majority of the shares of Pari
Passu Preferred and Conversion Common Shares, voting as a single class on a
Common Equivalent Basis, then outstanding, if required pursuant to
Section 3(c));

          (J) securities issued in connection with a Qualified IPO;
or

          (K) Permitted Issuances;

provided that the aggregate number of shares of Common issued or issuable pursuant to
clauses (H) and (I) above shall not exceed 100,000 in any twelve-month period;

          c. Effect on Conversion Price of Certain Events. For purposes of determining
the Series C Conversion Price under Section 7, the following shall be applicable:

     (i)
Issuance of Options. If the Corporation in any manner grants, issues or
sells any Options (other than any Options permitted by Section 7(b)(iii)) and the price
per
share for which Common is issuable upon the exercise of such Options, or upon

-12-

 

conversion or exchange of any Convertible Securities issuable upon exercise of such Options,
is less than the Series C Conversion Price in effect immediately prior to the time of the granting,
issuance or sale of such Options, then the total maximum number of shares of Common issuable upon
the exercise of such Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities issuable upon the exercise of such Options shall be deemed to be outstanding
and to have been issued and sold by the Corporation at the time of the granting, issuance or sale
of such Options for such price per share. For purposes of this paragraph, the “price per share for
which Common is issuable” shall be determined by dividing (A) the sum of (1) the total
amount, if any, received or receivable by the Corporation as consideration for the granting,
issuance or sale of such Options, plus (2) the minimum aggregate amount of additional
consideration payable to the Corporation upon exercise of all such Options, plus (3) in the
case of such Options which relate to Convertible Securities, the minimum aggregate amount of
additional consideration, if any, payable to the Corporation upon the issuance or sale of such
Convertible Securities and the conversion or exchange thereof, by (B) the total maximum
number of shares of Common 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. No further
adjustment of the Conversion Price shall be made when Convertible Securities are actually issued
upon the exercise of such Options or when Common is actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities.

     (ii) Issuance of Convertible Securities. If the Corporation in any manner issues
or sells any Convertible Securities and the price per share for which Common is issuable upon
conversion or exchange thereof is less than the Series C Conversion Price in effect immediately
prior to the time of such issuance or sale, then the maximum number of shares of Common issuable
upon conversion or exchange of such Convertible Securities shall be deemed to be outstanding and to
have been issued and sold by the Corporation at the time of the issuance or sale of such
Convertible Securities for such price per share. For the purposes of this paragraph, the “price per
share for which Common is issuable” shall be determined by dividing (A) the sum of (1) the
total amount received or receivable by the Corporation as consideration for the issue or sale of
such Convertible Securities, plus (2) the minimum aggregate amount of additional consideration, if
any, payable to the Corporation upon the conversion or exchange thereof, by (B) the total
maximum number of shares of Common issuable upon the conversion or exchange of all such Convertible
Securities. No further adjustment of the Series C Conversion Price shall be made when Common is
actually issued upon the conversion or exchange of such Convertible Securities, and if any such
issuance or sale of such Convertible Securities is made upon exercise of any Options for which
adjustments of the Series C Conversion Price had been or are to be made pursuant to other
provisions of this Section 7, no further adjustment of the conversion price shall be made
by reason of such issue or sale.

     (iii) Change in Option Price or Conversion Rate. If the purchase price provided
for in any Options, the additional consideration, if any, payable upon the conversion or exchange
of any Convertible Securities or the rate at which any Convertible Securities are convertible into
or exchangeable for Common changes at any

-13-

 

time, the Series C Conversion Price in effect at the time of such change shall be immediately
adjusted to the Series C Conversion Price that 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; provided, that, if such adjustment of the Series C Conversion Price would result in
an increase in the Series C Conversion Price then in effect, the Corporation will promptly give all
holders of Series C Preferred written notice of such increase. For purposes of this Section
7(c)(iii), if the terms of any Option or Convertible Security that was outstanding as of the
Series C Original Issuance Date are changed in the manner described in the immediately preceding
sentence, then such Option or Convertible Security and the Common deemed issuable upon exercise,
conversion or exchange thereof shall be deemed to have been issued as of the date of such change;
provided, that, no such change shall at any time cause the Series C Conversion Price hereunder to
be increased.

     (iv)
Treatment of Expired Options and Unexercised Convertible Securities. Upon
the expiration of any Option or the termination of any right to convert or exchange any Convertible
Security without the exercise of any such Option or right, the Series C Conversion Price then in
effect hereunder shall be adjusted immediately to the Series C Conversion Price that would have
been in effect at the time of such expiration or termination had such Option or Convertible
Security, to the extent outstanding immediately prior to such expiration or termination, never been
issued; provided, that, if such expiration or termination would result in an increase in the Series
C Conversion Price then in effect, the Corporation will promptly give all holders of Series C
Preferred written notice of such increase. For purposes of this Section 7(c)(iv), the
expiration or termination of any Option or Convertible Security that was outstanding as of the
Series C Original Issuance Date shall not cause the Series C Conversion Price hereunder to be
adjusted unless, and only to the extent that, a change in the terms of such Option or Convertible
Security caused it to be deemed to have been issued after the Series C Original Issuance Date.

     (v) Calculation of Consideration Received. If any Common, Option or Convertible
Security is issued or sold or deemed to have been issued or sold for cash, the consideration
received therefor shall be deemed to be the amount received by the Corporation therefor (net of
discounts, commissions and related expenses). If any Common, Option or Convertible Security is
issued or sold for a consideration other than cash, the amount of the consideration other than cash
received by the Corporation shall be the fair market value of such consideration as determined in
good faith by the Board. If any Common, Option or Convertible Security is issued to the owners of
the non-surviving entity in connection with any merger in which the Corporation is the surviving
corporation, the amount of consideration therefor shall be deemed to be the fair value of such
portion of the net assets and business of the non-surviving entity as is attributable to such
Common, Option or Convertible Security, as the case may be. The fair value of any consideration
other than cash and securities shall be the fair market value as determined in good faith by the
Board.

     (vi) Integrated Transactions. In case any Option is issued in connection with

-14-

 

the issuance or sale of other securities of the Corporation, together comprising one
integrated transaction in which no specific exercise price is allocated to such Option by
the parties thereto, the Option shall be deemed to have been issued at an exercise price of
$0.01.

     (vii) Treasury Shares. The number of shares of Common outstanding at any
given time shall not include shares owned or held by or for the account of the Corporation,
and the disposition of any shares so owned or held shall be considered an issuance or sale
of such shares.

     (viii) Record Date. If the Corporation takes a record of the holders of
Common for the purpose of entitling them (A) to receive a dividend or other distribution
payable in Common, Options or in Convertible Securities or (B) to subscribe for or purchase
Common, Options or Convertible Securities, then such record date shall be deemed to be the
date of the issue or sale of the shares of Common deemed to have been issued or sold upon
the declaration of such dividend or upon the making of such other distribution or the date
of the granting of such right of subscription or purchase, as the case may be.

     (ix) Subdivisions or Combinations of Common. If the Corporation at any
time subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or
more classes of its outstanding shares of Common into a greater number of shares, the
Series C Conversion Price in effect immediately prior to such subdivision shall be reduced
proportionately, and if the Corporation at any time combines (by reverse stock split or
otherwise) one or more classes of its outstanding shares of Common into a smaller number of
shares, the Series C Conversion Price in effect immediately prior to such combination shall
be increased proportionately.

     (x)
Recapitalization, Reorganization, Reclassification, Consolidation, Merger or
Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of
all or substantially all of the Corporation’s assets or other transaction, in each case which is
effected in such a manner that the holders of Common are entitled to receive (either directly or
upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common,
is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the
Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the
holders of a majority of the Series C Preferred then outstanding) to insure that each of the
holders of Series C Preferred shall thereafter have the right to acquire and receive, in lieu of or
in addition to (as the case may be) the shares of Common immediately theretofore acquirable and
receivable upon the conversion of such holder’s Series C Preferred, such shares of stock,
securities or assets as such holder would have received in connection with such Organic Change if
such holder had converted its Series C Preferred immediately prior to such Organic Change. In each
such case, the Corporation shall also make appropriate provisions (in form and substance reasonably
satisfactory to the holders of a majority of the Series C Preferred then outstanding) to insure
that the provisions of this Section 7(c) shall thereafter be applicable to the securities
issued in exchange for the Series C Preferred (including, in the case of any such consolidation,
merger or sale in which the successor entity or purchasing entity is other than the Corporation and
the value for the

-15-

 

Common reflected by the terms of such consolidation, merger or sale is less than the
Series C Conversion Price in effect immediately prior to such consolidation, merger or
sale, an immediate adjustment of the Series C Conversion Price to the value for the
Common so reflected and a corresponding immediate adjustment in the number of shares
of Common acquirable and receivable upon conversion of Series C Preferred). The
Corporation shall not effect any such consolidation, merger or sale, unless prior to the
consummation thereof, the successor entity (if other than the Corporation) resulting from
consolidation or merger or the entity purchasing such assets assumes by written
instrument (in form and substance satisfactory to the holders of a majority of the Series
C Preferred then outstanding) the obligation to deliver to each such holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions, such holder
may be entitled to acquire.

     (xi) Certain Other Events. If any event occurs of the type
contemplated by the provisions of this Section 7 but not expressly
provided for by such provisions (including, without limitation, the granting of
stock appreciation rights, phantom stock rights or other rights with equity
features), then the Board shall make an appropriate adjustment in the Series C
Conversion Price so as to protect the rights of the holders of Series C
Preferred; provided, that, no such adjustment shall increase the Series C
Conversion Price as otherwise determined pursuant to this Section 7 or
decrease the number of shares of Common issuable upon conversion of each share of
Series C Preferred.

          d. Notices.

     (i) Immediately upon any adjustment of the Series C Conversion Price,
the Corporation shall give written notice thereof to all holders of Series C
Preferred, setting forth in reasonable detail and certifying the calculation of
such adjustment.

     (ii) The Corporation shall give written notice to all holders of
Series C Preferred at least 10 days prior to the date on which the Corporation
closes its books or takes a record (A) with respect to any dividend or
distribution upon Common, (B) with respect to any pro rata subscription offer to
holders of Common or (C) for determining rights to vote with respect to any
Organic Change, dissolution or liquidation.

     (iii) The Corporation shall also give written notice to the holders of
Series C Preferred at least 10 days prior to the date on which any Organic
Change shall take place.

affidavit of the registered holder shall be satisfactory) of the ownership and the loss,
theft, destruction or mutilation of any certificate evidencing shares of Common or Series C
Preferred, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably
satisfactory to the Corporation, or, in the case of any such mutilation upon surrender of such
certificate, the Corporation shall (at its expense) execute and deliver in lieu of such
certificate a new certificate of like kind representing the number of shares of such class represented by
such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen,
destroyed or mutilated certificate, and dividends shall accrue on the Common or Series C Preferred
represented by such new certificate from the date to which dividends have been fully paid on
such lost, stolen, destroyed or mutilated certificate.

          c. Except as otherwise expressly provided hereunder, all notices referred to
herein shall be in writing and shall be delivered by registered or certified mail, return
receipt requested and postage prepaid, by reputable overnight courier service, charges prepaid or by

being sent by registered or certified mail, (ii) one business day after being deposited with such an
overnight courier service, and (iii) upon delivery, if by personal delivery, if mailed or
delivered (A) to the Corporation, at its principal executive offices, or (B) to any stockholder, at such

indicated by any such holder).

          d. Any of the rights, powers or preferences of the holders of Series C
Preferred and Conversion Common Shares set forth herein may be waived or otherwise defeased
by the affirmative written consent of the holders of at least a majority of the shares of
Series C Preferred and Conversion Common Shares then outstanding, voting as a single class on a

          (j) The transactions contemplated by the Transaction Documents comply with all tests of

          (k) Routine procedural matters such as service of process or qualification to do

respective rights or obligations of the parties to those documents;

          (n) With respect to the transactions contemplated by the Transaction Documents, there

          (o) All documents incorporated by reference into, or referred to in the Transaction
Documents, which are not themselves Transaction Documents, are enforceable against the
parties thereto in accordance with their terms.

     Whenever in this letter our opinion, with respect to the existence or absence of facts, is
intended to be based on our knowledge or attention, it is intended to signify that during
the course of our representation of the Company, no information has come to the attention of
those attorneys in this law firm who have represented the Company in connection with the
transactions described in this opinion letter which gave those attorneys actual knowledge of
the existence or absence of those facts. Except to the extent expressly set forth in this
letter, as noted above, we have not undertaken any independent investigation to determine
the existence or absence of any facts material to our opinion, and no inference as to our
knowledge of the existence or absence of those facts should be drawn from our representation
of the Company.

     Subject to the foregoing and the exclusions, assumptions and qualifications
contained below, we are of the opinion that:

     1. Based solely on the Good Standing Certificate (as defined in Exhibit “B”), the
Company is a corporation, validly existing and in good standing under the laws of the State of

Delaware. Based solely on the Authority Certificate (as defined in Exhibit “B”), the Company is
qualified as a foreign corporation in the State of Florida.

     2. The Company has all requisite corporate power and authority to execute and
deliver the Transaction Documents, and to close the transactions contemplated thereby. All
corporate action required to be taken by the Company to authorize the execution and delivery
of the Transaction Documents and the closing of the transactions contemplated thereby, have
been duly and properly taken.

     3. Each of the Transaction Documents constitutes the valid and binding obligation of
the Company, enforceable against the Company in accordance with its terms.

     4. The execution and delivery of the Transaction Documents by the Company, and
the closing of the transactions contemplated thereby do not conflict with, or result in any
violation of or default under, or give rise to a right of termination, cancellation or
acceleration of any obligation under, (i) any provision of the certificate of incorporation or bylaws of the
Company, as amended, or (ii) any statute, regulation or rule of the State of Delaware or
the State of Florida, which is applicable in our experience to transactions of the kind contemplated
by the Transaction Documents, or, to our knowledge, any injunction, order or decree of any
executive, legislative, judicial, administrative or regulatory body of the State of Delaware or the
State of Florida (collectively, a “Governmental Authority”) that is binding upon the Company.

     5. The shares of Series B Preferred Stock and the Series B Warrants underlying the
Series B Units, when issued in accordance with the provisions of the Amendment and upon
receipt of all consideration specified in the Amendment, will be validly issued, fully paid
and nonassessable.

     6. The shares of common stock issuable upon exercise of the Series B Warrants,
when issued in accordance with the provisions of the Series B Warrant Agreement and upon
receipt of all consideration specified in the Series B Warrant Agreement, will be validly
issued, fully paid and nonassessable.

     The opinions expressed herein are subject in all respects to the following limitations and
qualifications:

          (i) We express no opinion whatsoever as to the effect of bankruptcy, reorganization,
insolvency, fraudulent conveyance, fraudulent transfer, moratorium and other similar laws or

equity (including, without limitation, concepts of conscionability, materiality, reasonableness,
good faith and fair dealing) on the enforceability of the Transaction Documents regardless of
whether considered in a proceeding at law or in equity.

3. EXERCISE OF WARRANT

          3.1 Exercise.

          Each Warrant shall initially entitle the Holder thereof to purchase shares of Common Stock at
a per share exercise price equal to the Exercise Price (subject to adjustment as provided in
Section 5), in each case as provided herein and all on the terms and conditions and pursuant to the
provisions hereinafter set forth.

          3.2 Manner of Exercise.

          (a) From and after the Original Issue Date and until 5:00 P.M., New York, New York time, on
the Expiration Date, a Holder of a Warrant may from time to time exercise such Warrant, on any
Business Day, for all or any part of the number of shares of Common Stock purchasable
thereunder. In order to exercise a Warrant, in whole or in part, the Holder shall (i) deliver to
the Company at the Designated Office a written notice of the Holder’s election to exercise such
Warrant (an “Exercise Notice”), which Exercise Notice shall be irrevocable (except as otherwise
provided in Section 3.2(e)) and specify the number of shares of Common Stock being purchased,
together with the Warrant, (ii) pay to the Company the Warrant Price (the date on which both
such delivery and payment shall have first taken place being hereinafter sometimes referred to
as the “Exercise Date”) and (iii) if such Holder has not already done so, become a party to each
of the Shareholders Agreement and the Registration Rights Agreement by completing and executing
a signature page thereof. Such Exercise Notice shall be in the form of the subscription form
appearing as Annex A to Exhibit A, duly executed by the Holder or its duly authorized
agent or attorney.

          (b) Upon receipt of such Exercise Notice, Warrant and payment and any other materials
required to be provided under Section 3.2(a), the Company shall, as promptly as practicable, and
in any event within five (5) Business Days thereafter, execute (or cause to be executed) and
deliver (or cause to be delivered) to the Holder a certificate or certificates representing the
aggregate number of full shares of Common Stock issuable upon such exercise, together with
either any fraction of a share or cash in lieu of any fraction of a share, as hereafter provided
in Section 3.4. The stock certificate or certificates so delivered shall be, to the extent
possible, in such denomination or denominations as the exercising Holder shall reasonably
request in the Exercise Notice and shall be registered in the name of the Holder or the name of
its nominee. A Warrant shall be deemed to have been exercised and such certificate or
certificates shall be deemed to have been issued, and the Holder or any other Person so
designated to be named therein shall be deemed to have become a holder of record of such shares
for all purposes, as of the Exercise Date.

          (c) Payment of the Warrant Price may be made by check payable to the order of the Company
or, at the option of the Holder, by wire transfer of funds to an account designated by the
Company for such purpose.

          (d) If a Warrant shall have been exercised in part, the Company shall, at the time of
delivery of the certificate or certificates representing the shares of Common Stock being
issued, deliver to the Holder a new Warrant evidencing the rights of the Holder to

7

 

purchase the number of unexercised shares called for by such Warrant. Such new Warrant shall
in all other respects be identical with the original Warrant and subject to the terms of
this Agreement.

          (e) Notwithstanding the foregoing provisions of this Section 3.2, a Holder (i) may
expressly condition the effectiveness of any exercise of a Warrant upon the simultaneous closing
of the sale, in an offering registered under the Securities Act or pursuant to the exercise of
any drag-along or co-sale rights under the Shareholders Agreement, of the shares of Common Stock
as to which the conditional exercise is being made and (ii) may revoke any such conditional
exercise in the event that the closing of such sale shall not occur. In the event that such
simultaneous exercise and sale shall occur, the Company shall cooperate with such Holder and any
third parties involved in such sale to facilitate the issuance and sale of the shares of Common
Stock involved.

          3.3 Payment of Charges.

          All shares of Common Stock issuable upon the exercise of a Warrant pursuant to the terms
hereof shall be validly issued, fully paid and nonassessable, issued without violation of any
preemptive rights and free and clear of all Liens (other than, to the extent permitted by Section
9, any created by actions of the Holder). The Company shall pay all expenses in connection with the
issue or delivery thereof, unless such charge is imposed by law upon the Holder, in which case such
charge shall be paid by the Holder and the Company shall reimburse the Holder therefor.

          3.4 Fractional Shares.

          The Company shall not be required to issue a fractional share of Common Stock upon exercise of
any Warrant. As to any fraction of a share that the Holder of one or more Warrants, the rights
under which are exercised in the same transaction, would otherwise be entitled to purchase upon
such exercise, the Company shall, at its option, issue upon exercise either (i) the fractional
share of Common Stock to which the Holder of one or more Warrants would otherwise be entitled or
(ii) a cash adjustment in respect of such final fraction in an amount equal to the same fraction of
(A) the Current Market Price of one share of Common Stock on the Exercise Date, if the Common Stock
is then publicly traded or (B) the Book Value per share of Common Stock based on the most recent
available consolidated balance sheet of the Company, if the Common Stock is not then publicly
traded.

4. TRANSFER, DIVISION AND COMBINATION

          4.1 Transfer.

          Subject to compliance with Section 9 and the Shareholders Agreement, each transfer of a
Warrant and all rights hereunder, in whole or in part, shall be registered on the books of the
Company to be maintained for such purpose, upon surrender of a Warrant at the Designated Office,
together with a written assignment of such Warrant in the form of Annex B to Exhibit A, duly
executed by the Holder or its agent or attorney. Upon such surrender and delivery, (i) the Company
shall, subject to Section 9, execute and deliver a new Warrant or

8

 

Warrants in the name of the assignee or assignees and in the denominations specified in such
instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of
the original Warrant not so assigned and the original Warrant shall promptly be cancelled and (ii)
if not already a party to the Shareholders Agreement and the Registration Rights Agreement, each
assignee shall become a party to each of the Shareholders Agreement and the Registration Rights
Agreement by completing and executing a joinder agreement thereto. A Warrant, if properly assigned
in compliance with Section 9 and the Shareholders Agreement, may be exercised by the new Holder
for the purchase of shares of Common Stock without having a new Warrant issued.

          4.2 Division and Combination.

          Subject to compliance with the applicable provisions of this Agreement, a Warrant may be
divided or combined with other Warrants upon presentation thereof at the Designated Office,
together with a written notice specifying the names and denominations in which new Warrants are to
be issued, signed by the Holder or its agent or attorney. Subject to compliance with the
applicable provisions of this Agreement and the Shareholders Agreement as to any transfer which
may be involved in such division or combination, the Company shall execute and deliver a new
Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

          4.3 Expenses.

          The Company shall prepare, issue and deliver at its own expense any new Warrant or
Warrants required to be issued under this Section 4.

          4.4 Maintenance of Books.

          The Company agrees to maintain, at the Designated Office, books for the registration
and transfer of the Warrants.

5. EXERCISE PRICE; ANTIDILUTION PROVISIONS

          5.1 Exercise Price.

          The initial exercise price shall be $3.00 per share of Common Stock (subject to adjustment
from time to time as provided in this Section 5) (as so adjusted, the “Exercise Price”).

          5.2 Adjustments; Exceptions.

          (a) If and whenever on or after the Original Issue Date the Company issues or sells or, in
accordance with this Section 5, is deemed to have issued or sold, any shares of its Common Stock
for a consideration per share less than the Exercise Price in effect immediately prior to the time
of such issuance, then immediately upon such issuance or sale or deemed issuance or sale the
Exercise Price shall be reduced to the exercise price determined by dividing (i) the sum of
(1) the product derived by multiplying the Exercise Price in effect immediately prior to
such issuance or sale by the number of shares of

9

 

Common Deemed Outstanding immediately prior to such issuance or sale, plus (2) the consideration,
if any, received by the Company upon such issuance or sale, by (ii) the number of shares of Common
Deemed Outstanding immediately after such issue or sale.

          (b) Notwithstanding the foregoing, there shall be no adjustment in the Exercise
Price as a result of any issuance or sale (or deemed issuance or sale) of:

     (i) shares of Common Stock issued upon conversion of the Preferred Stock;

     (ii) shares of Common Stock issued upon the exercise of the Warrants or the Series C
Warrants;

     (iii) shares of Common Stock issued upon the exercise of Options or other
Convertible Securities outstanding as of March 14, 2007;

     (iv) securities issued pursuant to a Board-approved (including at least one of the

substantially all of the assets or other reorganization;

     (v) shares of Common Stock issued to Catalyst Capital Investments LLC, a Delaware
limited liability company pursuant to the Options granted under the Catalyst Letter
Agreements;

     (vi) shares of Common Stock or other securities issued as a dividend or distribution
on, or in connection with a split of or recapitalization of, any of the capital
stock of the Company;

     (vii) up to an aggregate of 250,000 shares of Common Stock reserved
for issuance per year pursuant to the Option Plan (subject to adjustment in the
event of stock splits, stock dividends, stock combinations, recapitalizations and
like occurrences) and shares of Common Stock reserved for issuance pursuant to the
Option Plan in lieu of the repayment of certain salary deferrals as approved by a
majority of the Board (including at least one of the Investor Directors), which
foregoing shares may be subject to Options or restricted stock awards granted under
the Option Plan; provided that any Options that expire or terminate unexercised or
any restricted stock awards that are repurchased by the Company pursuant to the
terms of such award shall not be counted toward the maximum number set forth in
this subparagraph (vii) unless and until such shares are subject to new restricted
stock awards (or new Options) pursuant to the terms of the Option Plan;

     (viii) shares of Common Stock issued or issuable (including
options to acquire such shares of Common Stock) to suppliers or third-party
service providers in connection with the provision of goods or services
pursuant to transactions in the ordinary course of business and approved by a
majority of the Board, including at least one of the Investor Directors;

10

 

     (ix) shares of Common Stock issued or issuable in connection with
bona-fide sponsored research, collaboration, technology license, development, OEM,
marketing or other similar agreements or strategic partnerships or joint ventures
entered into in the ordinary course of business and approved by a majority of the
Board, including at least one of the Investor Directors (and by at least a majority
of the shares of Preferred Stock and Conversion Common Shares, voting as a single
class on a Common Equivalent Basis, then outstanding, if required pursuant to
Section 3(c) of the Preferred Stock Certificates of Designation);

     (x) securities issued in connection with a Qualified IPO; or

     (xi) Permitted Issuances;

provided that the aggregate number of shares of Common issued or issuable pursuant to
clauses (viii) and (ix) above shall not exceed 100,000 in any twelve-month period.

          5.3 Effect on Exercise Price of Certain Events.

          For purposes of determining any adjustments to the Exercise Price under this Section 5,
the following shall be applicable:

          (a) Issuance of Options. If the Company in any manner grants, issues or sells any
Options (other than any Options permitted by Section 5.2(b)) and the price per share for which
Common Stock is issuable upon the exercise of such Options, or upon conversion or exchange of
any Convertible Securities issuable upon exercise of such Options, is less than the Exercise
Price in effect immediately prior to the time of the granting, issuance or sale of such Options,
then the total maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon conversion or exchange of the total maximum amount of such Convertible
Securities issuable upon the exercise of such Options shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the granting, issuance or sale of such
Options for such price per share. For purposes of this paragraph, the “price per share for which
Common Stock is issuable” shall be determined by dividing (i) the sum of (1) the total amount,
if any, received or receivable by the Company as consideration for the granting, issuance or
sale of such Options, plus (2) the minimum aggregate amount of additional consideration payable
to the Company upon exercise of all such Options, plus (3) in the case of such Options which
relate to Convertible Securities, the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the issuance or sale of such Convertible Securities and 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. No further adjustment of the
Exercise Price shall be made when Convertible Securities are actually issued upon the exercise
of such Options or when Common Stock actually issued upon the exercise of such Options or the
conversion or exchange of such Convertible Securities.

11

 

          (b) Issuance of Convertible Securities. If the Company in any manner issues or sells
any Convertible Securities and the price per share for which Common Stock is issuable upon
conversion or exchange thereof is less than the Exercise Price in effect immediately prior to the
time of such issuance or sale, then the maximum number of shares of Common Stock issuable upon
conversion or exchange of such Convertible Securities shall be deemed to be outstanding and to have
been issued and sold by the Company at the time of the issuance or sale of such Convertible
Securities for such price per share. For the purposes of this paragraph, the “price per share for
which Common Stock is issuable” shall be determined by dividing (i) the sum of (1) the total amount
received or receivable by the Company as consideration for the issue or sale of such Convertible
Securities, plus (2) the minimum aggregate amount of additional consideration, if any, payable to
the Company upon the conversion or exchange thereof, by (B) the total maximum number of shares of
Common Stock issuable upon the conversion or exchange of all such Convertible Securities. No
further adjustment of the Exercise Price shall be made when Common Stock is actually issued upon
the conversion or exchange of such Convertible Securities, and if any such issuance or sale of such
Convertible Securities is made upon exercise of any Options for which adjustments of the Exercise
Price had been or are to be made pursuant to other provisions of this Section 5, no further
adjustment of the Exercise Price shall be made by reason of such issue or sale.

          (c) Change in Option Price or Conversion Rate. If the purchase price
provided for in any Options, the additional consideration, if any, payable upon the conversion or
exchange of any Convertible Securities or the rate at which any Convertible Securities are
convertible into or exchangeable for Common Stock changes at any time, the Exercise Price in effect
at the time of such change shall be immediately adjusted to the Exercise Price that 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; provided, that, if such adjustment of the Exercise
Price would result in an increase in the Exercise Price then in effect, the Company will promptly
give all Holders written notice of such increase. For purposes of this Section 5.3.(c), if the
terms of any Option or Convertible Security that was outstanding as of the Original Issue Date are
changed in the manner described in the immediately preceding sentence, then such Option or
Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange
thereof shall be deemed to have been issued as of the date of such change; provided, that, no such
change shall at any time cause the Exercise Price hereunder to be increased.

          (d) Treatment of Expired Options and Unexercised Convertible Securities.Upon the
expiration of any Option or the termination of any right to convert or exchange any Convertible
Security without the exercise of any such Option or right, the Exercise Price then in effect
hereunder shall be adjusted immediately to the Exercise Price that would have been in effect at the
time of such expiration or termination had such Option or Convertible Security, to the extent
outstanding immediately prior to such expiration or termination, never been issued; provided, that,
if such expiration or termination would result in an increase in the Exercise Price then in effect,
the Company will promptly give all Holders of Warrants written notice of such increase. For
purposes of this Section 5.3(d), the expiration or

12

 

termination of any Option or Convertible Security that was outstanding as of the Original Issue
Date shall not cause the Exercise Price hereunder to be adjusted unless, and only to the extent
that, a change in the terms of such Option or Convertible Security caused it to be deemed to have
been issued after the Original Issue Date.

          (e) Calculation of Consideration Received. If any Common Stock, Option or Convertible
Security is issued or sold or deemed to have been issued or sold for cash, the consideration
received therefor shall be deemed to be the amount received by the Company therefor (net of
discounts, commissions and related expenses). If any Common Stock, Option or Convertible Security
is issued or sold for a consideration other than cash, the amount of the consideration other than
cash received by the Company shall be the fair market value of such consideration as determined in
good faith by the Board. If any Common Stock, Option or Convertible Security is issued to the
owners of the non-surviving entity in connection with any merger in which the Company is the
surviving corporation, the amount of consideration therefor shall be deemed to be the fair value of
such portion of the net assets and business of the non-surviving entity as is attributable to such
Common Stock, Option or Convertible Security, as the case may be. The fair value of any
consideration other than cash and securities shall be the fair market value as determined in good
faith by the Board.

          (f) Integrated Transactions. In case any Option is issued in connection with the
issuance or sale of other securities of the Company, together comprising one integrated transaction
in which no specific exercise price is allocated to such Option by the parties thereto, the Option
shall be deemed to have been issued at an exercise price of $0.01.

          (g) Treasury Shares. 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, and the
disposition of any shares so owned or held shall be considered an issuance or sale of such shares.

          (h) Record Date. If the Company takes a record of the holders of Common Stock for the purpose
of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options
or in 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 issue or sale
of the shares of Common Stock deemed to have been issued or sold upon the declaration of such
dividend or upon the making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

          (i) Subdivisions or Combinations of Common Stock. If the Company at any time
subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes
of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in
effect immediately prior to such subdivision shall be reduced proportionately, and if the Company
at any time combines (by reverse stock split or otherwise) one or more classes of its outstanding
shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately
prior to such combination shall be increased proportionately.

13

 

          (j)
Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale.
Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or
substantially all of the Company’s assets or other transaction, in each case which is effected in
such a manner that the holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in exchange for Common
Stock, is referred to herein as an “Organic Change.” Prior to the consummation of any Organic
Change, the Company shall make appropriate provisions (in form and substance reasonably
satisfactory to the Majority Warrant Holders) to insure that each of the Holders shall thereafter
have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares
of Common Stock immediately theretofore acquirable and receivable upon the exercise of such
Holder’s Warrant, such shares of stock, securities or assets as such Holder would have received in
connection with such Organic Change if such Holder had exercised its Warrant immediately prior to
such Organic Change. In each such case, the Company shall also make appropriate provisions (in form
and substance reasonably satisfactory to the Majority Warrant Holders) to insure that the
provisions of this Section 5 shall thereafter be applicable to the securities issued upon exercise
of the Warrants (including, in the case of any such consolidation, merger or sale in which the
successor entity or purchasing entity is other than the Company and the value for the Common Stock
reflected by the terms of such consolidation, merger or sale is less than the Exercise Price in
effect immediately prior to such consolidation, merger or sale, an immediate adjustment of the
Exercise Price to the value for the Common Stock so reflected and a corresponding immediate
adjustment in the number of shares of Common Stock acquirable and receivable upon the exercise of
the Warrants). The Company shall not effect any such consolidation, merger or sale, unless prior to
the consummation thereof, the successor entity (if other than the Company) resulting from
consolidation or merger or the entity purchasing such assets assumes by written instrument (in form
and substance satisfactory to the Majority Warrant Holders) the obligation to deliver to each such
Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

          (k) Certain Other Events. If any event occurs of the type contemplated by the
provisions of this Section 5 but not expressly provided for by such provisions (including, without
limitation, the granting of stock appreciation rights, phantom stock rights or other rights with
equity features), then the Board shall make an appropriate adjustment in the Exercise Price so as
to protect the rights of the Holders of Warrants; provided that no such adjustment shall increase
the Exercise Price as otherwise determined pursuant to this Section 5 or decrease the number of
shares of Common Stock issuable upon exercise of each Warrant.

14

 

          5.4 Notices.

          Immediately upon any adjustment of the Exercise Price, the Company shall give written notice
thereof to all Holders, setting forth in reasonable detail and certifying the calculation of such
adjustment.

6. NO IMPAIRMENT

          The Company shall not by any action, including amending its charter documents or through any
reorganization, reclassification, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other similar voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of this Agreement, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may be necessary or
appropriate to protect the rights of the Holder of any Warrant against impairment. Without limiting
the generality of the foregoing, the Company shall take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable
shares of Common Stock upon the exercise of the Warrants, free and clear of all Liens (other than,
to the extent permitted by Section 9, any created by actions of the Holder), and shall use its
commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be necessary to enable the Company to
perform its obligations under this Agreement.

			
	7.	 	RESERVATION AND AUTHORIZATION OF COMMON STOCK: REGISTRATION WITH OR APPROVAL OF ANY GOVERNMENTAL AUTHORITY

          From and after the Original Issue Date, the Company shall at all times reserve and keep
available for issuance upon the exercise of the Warrants such number of its authorized but unissued
shares of Common Stock as will be sufficient to permit the exercise in full of all outstanding
Warrants. All shares of Common Stock issuable pursuant to the terms hereof, when issued upon
exercise of Warrants with payment therefor in accordance with the terms hereof, shall be duly and
validly issued and fully paid and nonassessable, not subject to preemptive rights and shall be free
and clear of all Liens (other than, to the extent permitted by Section 9, any created by actions of
the Holder). Before taking any action that would result in an adjustment in the number of shares of
Common Stock for which the Warrants are exercisable, the Company shall obtain all such
authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction over such action. If any shares of Common Stock

qualification with any governmental authority under any federal or state law (other than under the
Securities Act or any state securities law) before such shares may be so issued, the Company will
in good faith and as expeditiously as possible and at its expense endeavor to cause such shares to

signature page thereof. The Company shall not be obligated to register any transfer of Warrants and
no such purported transfer shall be effective unless and until the transferee has executed and
delivered a joinder agreement pursuant to which such assignee becomes a party to the Shareholders
Agreement and the Registration Rights Agreement.

          9.2 Legends.

          (a) Each Warrant Certificate shall be stamped or otherwise imprinted with a legend in
substantially the following form:

     (i) “NEITHER THE WARRANTS REPRESENTED BY THIS
CERTIFICATE NOR ANY OF THE SECURITIES ISSUABLE UPON EXERCISE THEREOF HAVE BEEN
REGISTERED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, AND NEITHER THE WARRANTS REPRESENTED BY THIS CERTIFICATE NOR

FURNISHED BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT
CHARGE.”

          (b) Each certificate for shares of Warrant Stock shall be stamped or otherwise
imprinted with a legend in substantially the following form:

HAVE NOT BEEN REGISTERED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED, SOLD, PLEDGED,
HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS SUCH DISPOSITION IS PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND

THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE.”

          (c) In addition, Warrant Certificates and any certificates for shares of Warrant
Stock shall bear any legends required by applicable state law. When any Warrants or shares of
Warrant Stock have been registered under the Securities Act, and such Warrants or shares of
Warrant Stock have been sold pursuant to such registration or pursuant to Rule 144 under the
Securities Act or are eligible to be sold pursuant to paragraph (k) of such Rule, the Holder
of
such Warrants or shares of Warrant Stock shall be entitled to exchange, as the case may be,
the
Warrant Certificate representing such Warrants for a Warrant Certificate, or a certificate
representing such shares of Warrant Stock for a new certificate, in each case not bearing the
legend required by clause (a)(i) or (b)(i), as the case may be, of this Section 9. If any
Warrants
or shares of Warrant Stock cease to be subject to this Agreement or the Shareholders
Agreement,
as the case may be, the Holder of such Warrants or Warrant Stock shall be entitled to
exchange,
as the case may be, the Warrant Certificate representing such Warrants for a Warrant
Certificate,
or a certificate representing such shares of Warrant Stock for a new certificate, in each case
not

18

 

bearing the legend required by clauses (a)(ii), (a)(iii) or (b)(ii), as the case may be, of
this Section

elsewhere in this Agreement, such Holder will not directly or indirectly Transfer any Warrants
(or solicit any offers to buy, purchase or otherwise acquire or take a pledge of any Warrants) in
violation of the Securities Act, applicable state securities or “blue sky” laws or any rules or
regulations thereunder, and such Holder will not Transfer any Warrants unless the conditions set
forth in the legend required by clause (a)(i) of this Section 9. are satisfied.

10. LOSS OR MUTILATION

          Upon receipt by the Company from any Holder of evidence reasonably satisfactory to it of the
ownership of and the loss, theft, destruction or mutilation of a Warrant Certificate and an
indemnity reasonably satisfactory to it (it being understood that the written indemnification
agreement of or affidavit of loss of a Holder of an Original Warrant shall be a sufficient
indemnity) and, in case of mutilation, upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder; provided,
however, in the case of mutilation, no indemnity shall be required if a Warrant Certificate
in identifiable form is surrendered to the Company for cancellation.

11. OFFICE OF THE COMPANY

          As long as any of the Warrants remain outstanding, the Company shall maintain an office or
agency, which may be the principal executive offices of the Company (the “Designated Office”),

as provided in this Agreement. Such Designated Office shall initially be the office of the Company

to time change the Designated Office to another office of the Company or its agent within the
United States by notice given to all registered holders of Warrants at least ten (10) Business Days
prior to the effective date of such change.

present intention of holding it for purposes of investment, and that it has no present intention of
selling it in a public distribution in violation of the federal securities laws or any applicable
state securities laws, provided, that nothing contained herein shall prevent such Holder from
transferring such Warrant in compliance with the provisions of Section 9, and (iii) it understands
that the Warrant has not been registered under the Securities Act, or applicable state securities
laws, and is being issued in reliance on exemptions from such registration requirements and that,
as a result, the Warrant may not be re-offered or resold except in compliance with Section 9.

giving of notice or both, (i) violate any provision of the Company’s Certificate of Incorporation
or By-laws or (ii) violate any requirement of law or any material agreement to which the Company is
a party. The Warrants have been duly executed and delivered by the Company, have been duly

          Each Holder of Warrants, in addition to being entitled to exercise its rights granted by law,
including recovery of damages, shall be entitled to specific performance of its rights provided
under this Agreement. The Company agrees that monetary damages would not be adequate compensation

agrees, in an action for specific performance, to waive the defense that a remedy at law would be
adequate.

3. EXERCISE OF WARRANT

             3.1 Exercise.

          Each Warrant shall initially entitle the Holder thereof to purchase shares of Common Stock at
a per share exercise price equal to the Exercise Price (subject to adjustment as provided in
Section 5), in each case as provided herein and all on the terms and conditions and pursuant to the
provisions hereinafter set forth.

             3.2 Manner of Exercise.

          (a) From and after the Original Issue Date and until 5:00 P.M., New York, New York time,
on the Expiration Date, a Holder of a Warrant may from time to time exercise such Warrant, on
any Business Day, for all or any part of the number of shares of Common Stock purchasable
thereunder. In order to exercise a Warrant, in whole or in part, the Holder shall (i) deliver
to the Company at the Designated Office a written notice of the Holder’s election to exercise
such Warrant (an “Exercise Notice”), which Exercise Notice shall be irrevocable (except as
otherwise provided in Section 3.2(e)) and specify the number of shares of Common Stock being
purchased, together with the Warrant, (ii) pay to the Company the Warrant Price (the date on
which both such delivery and payment shall have first taken place being hereinafter sometimes
referred to as the “Exercise Date”) and (iii) if such Holder has not already done so, become a
party to each of the Shareholders Agreement and the Registration Rights Agreement by completing
and executing a signature page thereof Such Exercise Notice shall be in the form of the
subscription form appearing as Annex A to Exhibit A, duly executed by the
Holder or its duly authorized agent or attorney.

          (b) Upon receipt of such Exercise Notice, Warrant and payment and any other materials
required to be provided under Section 3.2(a), the Company shall, as promptly as practicable,
and in any event within five (5) Business Days thereafter, execute (or cause to be executed)
and deliver (or cause to be delivered) to the Holder a certificate or certificates representing
the aggregate number of full shares of Common Stock issuable upon such exercise, together with
either any fraction of a share or cash in lieu of any fraction of a share, as hereafter provided
in Section 3.4. The stock certificate or certificates so delivered shall be, to the extent
possible, in such denomination or denominations as the exercising Holder shall reasonably
request in the Exercise Notice and shall be registered in the name of the Holder or the name of
its nominee. A Warrant shall be deemed to have been exercised and such certificate or
certificates shall be deemed to have been issued, and the Holder or any other Person so
designated to be named therein shall be deemed to have become a holder of record of such shares
for all purposes, as of the Exercise Date.

          (c) Payment of the Warrant Price may be made by check payable to the order of the Company
or, at the option of the Holder, by wire transfer of funds to an account designated by the
Company for such purpose.

          (d) If a Warrant shall have been exercised in part, the Company shall, at the time of
delivery of the certificate or certificates representing the shares of Common Stock being
issued, deliver to the Holder a new Warrant evidencing the rights of the Holder to

7

 

purchase the number of unexercised shares called for by such Warrant. Such new Warrant
shall in all other respects be identical with the original Warrant and subject to the terms of
this Agreement.

          (e) Notwithstanding the foregoing provisions of this Section 3.2, a Holder (i)
may expressly condition the effectiveness of any exercise of a Warrant upon the
simultaneous closing of the sale, in an offering registered under the Securities
Act or pursuant to the exercise of any drag-along or co-sale rights under the
Shareholders Agreement, of the shares of Common Stock as to which the conditional
exercise is being made and (ii) may revoke any such conditional exercise in the
event that the closing of such sale shall not occur. In the event that such
simultaneous exercise and sale shall occur, the Company shall cooperate with such
Holder and any third parties involved in such sale to facilitate the issuance and
sale of the shares of Common Stock involved.

             3.3 Payment of Charges.

     All shares of Common Stock issuable upon the exercise of a Warrant pursuant to
the terms hereof shall be validly issued, fully paid and nonassessable, issued without
violation of any preemptive rights and free and clear of all Liens (other than, to the
extent permitted by Section 9, any created by actions of the Holder). The Company
shall pay all expenses in connection with the issue or delivery thereof, unless such
charge is imposed by law upon the Holder, in which case such charge shall be paid by
the Holder and the Company shall reimburse the Holder therefor.

             3.4 Fractional Shares.

          The Company shall not be required to issue a fractional share of Common Stock
upon exercise of any Warrant. As to any fraction of a share that the Holder of one or
more Warrants, the rights under which are exercised in the same transaction, would
otherwise be entitled to purchase upon such exercise, the Company shall, at its
option, issue upon exercise either (i) the fractional share of Common Stock to which
the Holder of one or more Warrants would otherwise be entitled or (ii) a cash
adjustment in respect of such final fraction in an amount equal to the same fraction
of (A) the Current Market Price of one share of Common Stock on the Exercise Date, if
the Common Stock is then publicly traded or (B) the Book Value per share of Common
Stock based on the most recent available consolidated balance sheet of the Company, if
the Common Stock is not then publicly traded.

4. TRANSFER, DIVISION AND
COMBINATION

             4.1 Transfer.

          Subject to compliance with Section 9 and the Shareholders Agreement, each
transfer of a Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of a Warrant at the Designated Office, together with a written assignment of
such Warrant in the form of Annex B to Exhibit A, duly executed by the Holder or its
agent or attorney. Upon such surrender and delivery, (i) the Company shall, subject to
Section 9, execute and deliver a new Warrant or

8

 

Warrants in the name of the assignee or assignees and in the denominations specified in such
instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of
the original Warrant not so assigned and the original Warrant shall promptly be cancelled and (ii)
if not already a party to the Shareholders Agreement and the Registration Rights Agreement, each
assignee shall become a party to each of the Shareholders Agreement and the Registration Rights
Agreement by completing and executing a joinder agreement thereto. A Warrant, if properly assigned
in compliance with Section 9 and the Shareholders Agreement, may be exercised by the new Holder for
the purchase of shares of Common Stock without having a new Warrant issued.

             4.2 Division and Combination.

          Subject to compliance with the applicable provisions of this Agreement, a Warrant may be
divided or combined with other Warrants upon presentation thereof at the Designated Office,
together with a written notice specifying the names and denominations in which new Warrants are to
be issued, signed by the Holder or its agent or attorney. Subject to compliance with the applicable
provisions of this Agreement and the Shareholders Agreement as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such
notice.

             4.3 Expenses.

          The Company shall prepare, issue and deliver at its own expense any new Warrant or
Warrants required to be issued under this Section 4.

             4.4 Maintenance of Books.

          The Company agrees to maintain, at the Designated Office, books for the registration
and transfer of the Warrants.

5. EXERCISE PRICE; ANTIDILUTION PROVISIONS

             5.1 Exercise Price.

          The initial exercise price shall be $3.00 per share of Common Stock (subject to adjustment
from time to time as provided in this Section 5) (as so adjusted, the “Exercise Price”).

             5.2 Adjustments; Exceptions.

          (a) If and whenever on or after the Original Issue Date the Company issues or sells or, in
accordance with this Section 5, is deemed to have issued or sold, any shares of its Common Stock
for a consideration per share less than the Exercise Price in effect immediately prior to the time
of such issuance, then immediately upon such issuance or sale or deemed issuance or sale the
Exercise Price shall be reduced to the exercise price determined by dividing (i) the
sum of (1) the product derived by multiplying the Exercise Price in effect immediately prior
to such issuance or sale by the number of shares of

9

 

Common Deemed Outstanding immediately prior to such issuance or sale, plus (2) the consideration, if
any, received by the Company upon such issuance or sale, by (ii) the number of shares of
Common Deemed Outstanding immediately after such issue or sale.

          (b) Notwithstanding the foregoing, there shall be no adjustment in the Exercise Price as a result of any issuance or sale (or deemed issuance or
sale) of:

     (i) shares of Common Stock issued upon conversion of the Preferred
Stock;

     (ii) shares of Common Stock issued upon the exercise of the Warrants
or the Series B Warrants;

     (iii) shares of Common Stock issued upon the exercise of Options or
other Convertible Securities outstanding as of March 14, 2007;

     (iv) securities issued pursuant to a Board-approved (including at least
one of the Investor Directors) bona fide acquisition of an entity by
merger, purchase of substantially all of the assets or other
reorganization;

     (v) shares of Common Stock issued to Catalyst Capital Investments
LLC, a Delaware limited liability company pursuant to the Options
granted under the Catalyst Letter Agreements;

     (vi) shares of Common Stock or other securities issued as a dividend or distribution on, or in
connection with a split of or recapitalization of, any of the capital stock of the Company;

     (vii) up to an aggregate of 250,000 shares of Common Stock
reserved for issuance per year pursuant to the Option Plan (subject to
adjustment in the event of stock splits, stock dividends, stock
combinations, recapitalizations and like occurrences) and shares of Common
Stock reserved for issuance pursuant to the Option Plan in lieu of the
repayment of certain salary deferrals as approved by a majority of the
Board (including at least one of the Investor Directors), which foregoing
shares may be subject to Options or restricted stock awards granted under
the Option Plan; provided that any Options that expire or terminate
unexercised or any restricted stock awards that are repurchased by the
Company pursuant to the terms of such award shall not be counted toward the
maximum number set forth in this subparagraph (vii) unless and until such
shares are subject to new restricted stock awards (or new Options) pursuant
to the terms of the Option Plan;

     (viii) shares of Common Stock issued or issuable (including
options to acquire such shares of Common Stock) to suppliers or third-party
service providers in connection with the provision of goods or services
pursuant to transactions in the ordinary course of business and approved by
a majority of the Board, including at least one of the Investor Directors;

10

 

     (ix) shares of Common Stock issued or issuable in connection with
bona-fide sponsored research, collaboration, technology license, development,
OEM, marketing or other similar agreements or strategic partnerships or joint
ventures entered into in the ordinary course of business and approved by a majority
of the Board, including at least one of the Investor Directors (and by at least a
majority of the shares of Preferred Stock and Conversion Common Shares, voting as a
single class on a Common Equivalent Basis, then outstanding, if required pursuant to
Section 3(c) of the Preferred Stock Certificates of Designation);

     (x) securities issued in connection with a Qualified IPO; or

     (xi) Permitted Issuances;

          provided that the aggregate number of shares of Common issued or issuable pursuant to
clauses (viii) and (ix) above shall not exceed 100,000 in any twelve-month period.

          5.3 Effect on Exercise Price of Certain Events.

          For purposes of determining any adjustments to the Exercise Price under this Section 5,
the following shall be applicable:

          (a) Issuance of Options. If the Company in any manner grants, issues or sells any
Options (other than any Options permitted by Section 5,2(b)) and the price per share for which
Common Stock is issuable upon the exercise of such Options, or upon conversion or exchange of
any Convertible Securities issuable upon exercise of such Options, is less than the Exercise
Price in effect immediately prior to the time of the granting, issuance or sale of such Options,
then the total maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon conversion or exchange of the total maximum amount of such Convertible
Securities issuable upon the exercise of such Options shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the granting, issuance or sale of such
Options for such price per share. For purposes of this paragraph, the “price per share for which
Common Stock is issuable” shall be determined by dividing (i) the sum of (1) the total amount,
if any, received or receivable by the Company as consideration for the granting, issuance or
sale of such Options, plus (2) the minimum aggregate amount of additional consideration payable
to the Company upon exercise of all such Options, plus (3) in the case of such Options which
relate to Convertible Securities, the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the issuance or sale of such Convertible Securities and 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. No further adjustment of the
Exercise Price shall be made when Convertible Securities are actually issued upon the exercise
of such Options or when Common Stock actually issued upon the exercise of such Options or the
conversion or exchange of such Convertible Securities.

11

 

          (b) Issuance of Convertible Securities. If the Company in any manner issues or
sells any Convertible Securities and the price per share for which Common Stock is issuable upon
conversion or exchange thereof is less than the Exercise Price in effect immediately prior to
the time of such issuance or sale, then the maximum number of shares of Common Stock issuable
upon conversion or exchange of such Convertible Securities shall be deemed to be outstanding and
to have been issued and sold by the Company at the time of the issuance or sale of such
Convertible Securities for such price per share. For the purposes of this paragraph, the “price
per share for which Common Stock is issuable” shall be determined by dividing (i) the sum of (1)
the total amount received or receivable by the Company as consideration for the issue or sale of
such Convertible Securities, plus (2) the minimum aggregate amount of additional consideration,
if any, payable to the Company upon the conversion or exchange thereof, by (B) the total maximum
number of shares of Common Stock issuable upon the conversion or exchange of all such
Convertible Securities. No further adjustment of the Exercise Price shall be made when Common
Stock is actually issued upon the conversion or exchange of such Convertible Securities, and if
any such issuance or sale of such Convertible Securities is made upon exercise of any Options
for which adjustments of the Exercise Price had been or are to be made pursuant to other
provisions of this Section 5, no further adjustment of the Exercise Price shall be made by
reason of such issue or sale.

          (c) Change in Option Price or Conversion Rate. If the purchase price
provided for in any Options, the additional consideration, if any, payable upon the conversion
or exchange of any Convertible Securities or the rate at which any Convertible Securities are
convertible into or exchangeable for Common Stock changes at any time, the Exercise Price in
effect at the time of such change shall be immediately adjusted to the Exercise Price that 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; provided, that, if such adjustment
of the Exercise Price would result in an increase in the Exercise Price then in effect, the
Company will promptly give all Holders written notice of such increase. For purposes of this
Section 5.3(c), if the terms of any Option or Convertible Security that was outstanding as of
the Original Issue Date are changed in the manner described in the immediately preceding
sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon
exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of
such change; provided, that, no such change shall at any time cause the Exercise Price hereunder
to be increased.

          (d) Treatment of Expired Options and Unexercised Convertible Securities. Upon the
expiration of any Option or the termination of any right to convert or exchange any Convertible
Security without the exercise of any such Option or right, the Exercise Price then in effect
hereunder shall be adjusted immediately to the Exercise Price that would have been in effect at the
time of such expiration or termination had such Option or Convertible Security, to the extent
outstanding immediately prior to such expiration or termination, never been issued; provided, that,
if such expiration or termination would result in an increase in the Exercise Price then in effect,
the Company will promptly give all Holders of Warrants written notice of such increase. For
purposes of this Section 5.3(d), the expiration or

12

 

termination of any Option or Convertible Security that was outstanding as of the Original Issue
Date shall not cause the Exercise Price hereunder to be adjusted unless, and only to the extent
that, a change in the terms of such Option or Convertible Security caused it to be deemed to have
been issued after the Original Issue Date.

          (e) Calculation of Consideration Received. If any Common Stock, Option or Convertible
Security is issued or sold or deemed to have been issued or sold for cash, the consideration
received therefor shall be deemed to be the amount received by the Company therefor (net of
discounts, commissions and related expenses). If any Common Stock, Option or Convertible Security
is issued or sold for a consideration other than cash, the amount of the consideration other than
cash received by the Company shall be the fair market value of such consideration as determined in
good faith by the Board. If any Common Stock, Option or Convertible Security is issued to the
owners of the non-surviving entity in connection with any merger in which the Company is the
surviving corporation, the amount of consideration therefor shall be deemed to be the fair value of
such portion of the net assets and business of the non-surviving entity as is attributable to such
Common Stock, Option or Convertible Security, as the case may be. The fair value of any
consideration other than cash and securities shall be the fair market value as determined in good
faith by the Board.

          (f) Integrated Transactions. In case any Option is issued in connection with the issuance or
sale of other securities of the Company, together comprising one integrated transaction in which no
specific exercise price is allocated to such Option by the parties thereto, the Option shall be
deemed to have been issued at an exercise price of $0.01.

          (g) Treasury Shares. 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, and the
disposition of any shares so owned or held shall be considered an issuance or sale of such shares.

          (h) Record Date. If the Company takes a record of the holders of Common Stock for the
purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock,
Options or in 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 issue or sale
of the shares of Common Stock deemed to have been issued or sold upon the declaration of such
dividend or upon the making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

          (i) Subdivisions or Combinations of Common Stock. If the Company at any time
subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes
of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in
effect immediately prior to such subdivision shall be reduced proportionately, and if the Company
at any time combines (by reverse stock split or otherwise) one or more classes of its outstanding
shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately
prior to such combination shall be increased proportionately.

13

 

          (j) Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale.
Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or
substantially all of the Company’s assets or other transaction, in each case which is effected in
such a manner that the holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in exchange for Common
Stock, is referred to herein as an “Organic Change” Prior to the consummation of any Organic
Change, the Company shall make appropriate provisions (in form and substance reasonably
satisfactory to the Majority Warrant Holders) to insure that each of the Holders shall thereafter
have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares
of Common Stock immediately theretofore acquirable and receivable upon the exercise of such
Holder’s Warrant, such shares of stock, securities or assets as such Holder would have received in
connection with such Organic Change if such Holder had exercised its Warrant immediately prior to
such Organic Change. In each such case, the Company shall also make appropriate provisions (in form
and substance reasonably satisfactory to the Majority Warrant Holders) to insure that the
provisions of this Section 5 shall thereafter be applicable to the securities issued upon exercise
of the Warrants (including, in the case of any such consolidation, merger or sale in which the
successor entity or purchasing entity is other than the Company and the value for the Common Stock
reflected by the terms of such consolidation, merger or sale is less than the Exercise Price in
effect immediately prior to such consolidation, merger or sale, an immediate adjustment of the
Exercise Price to the value for the Common Stock so reflected and a corresponding immediate
adjustment in the number of shares of Common Stock acquirable and receivable upon the exercise of
the Warrants). The Company shall not effect any such consolidation, merger or sale, unless prior to
the consummation thereof, the successor entity (if other than the Company) resulting from
consolidation or merger or the entity purchasing such assets assumes by written instrument (in form
and substance satisfactory to the Majority Warrant Holders) the obligation to deliver to each such
Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

          (k) Certain Other Events. If any event occurs of the type contemplated by the
provisions of this Section 5 but not expressly provided for by such provisions (including, without
limitation, the granting of stock appreciation rights, phantom stock rights or other rights with
equity features), then the Board shall make an appropriate adjustment in the Exercise Price so as
to protect the rights of the Holders of Warrants; provided that no such adjustment shall increase
the Exercise Price as otherwise determined pursuant to this Section 5 or decrease the number of
shares of Common Stock issuable upon exercise of each Warrant.

14

 

             5.4 Notices.

          Immediately upon any adjustment of the Exercise Price, the Company shall give written notice
thereof to all Holders, setting forth in reasonable detail and certifying the calculation of such
adjustment.

6. NO IMPAIRMENT

          The Company shall not by any action, including amending its charter documents or through any
reorganization, reclassification, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other similar voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of this Agreement, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may be necessary or
appropriate to protect the rights of the Holder of any Warrant against impairment. Without limiting
the generality of the foregoing, the Company shall take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable
shares of Common Stock upon the exercise of the Warrants, free and clear of all Liens (other than,
to the extent permitted by Section 9, any created by actions of the Holder), and shall use its
commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be necessary to enable the Company to
perform its obligations under this Agreement.

	7.	 	RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR APPROVAL OF ANY
GOVERNMENTAL AUTHORITY

          From and after the Original Issue Date, the Company shall at all times reserve and keep
available for issuance upon the exercise of the Warrants such number of its authorized but unissued
shares of Common Stock as will be sufficient to permit the exercise in full of all outstanding
Warrants. All shares of Common Stock issuable pursuant to the terms hereof, when issued upon
exercise of Warrants with payment therefor in accordance with the terms hereof, shall be duly and
validly issued and fully paid and nonassessable, not subject to preemptive rights and shall be free
and clear of all Liens (other than, to the extent permitted by Section 9, any created by actions of
the Holder). Before taking any action that would result in an adjustment in the number of shares of
Common Stock for which the Warrants are exercisable, the Company shall obtain all such
authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction over such action. If any shares of Common Stock
required to be reserved for issuance upon exercise of Warrants require registration or
qualification with any governmental authority under any federal or state law (other than under the
Securities Act or any state securities law) before such shares may be so issued, the Company will
in good faith and as expeditiously as possible and at its expense endeavor to cause such shares to
be duly registered.

15

 

8. NOTICE OF CORPORATE ACTIONS; TAKING OF RECORD; TRANSFER BOOKS

             8.1 Notices of Corporate Actions.

          In the event of: (a) any taking by the Company of a record of the holders of any class of

Company), or any right to subscribe for, purchase or otherwise acquire any shares of capital stock
of any class or any other securities, (b) any capital reorganization of the Company, any

dissolution, liquidation or winding-up of the Company, (d) any amendment of the Certificate of

any such record is to be taken for the purpose of such dividend, distribution or right, and the
amount and character of such dividend, distribution or right, (ii) in the case of a reorganization,
reclassification, recapitalization, consolidation, merger, transfer, disposition, dissolution,
liquidation or winding-up, the date or expected date on which any such reorganization,
reclassification, recapitalization, consolidation, merger, transfer, disposition, dissolution,
liquidation or winding-up is to take place, the time, if any such time is to be fixed, as of which
the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock
for the shares of stock, securities or assets deliverable upon such reorganization,
reclassification, recapitalization, consolidation, merger, transfer, disposition, dissolution,
liquidation or winding-up and a description in reasonable detail of the transaction and (iii) in
case of an amendment of the Certificate of Incorporation or any registration or public offering of
Common Stock, the expected date of such event and a description in reasonable detail of the event.
Such notice shall be mailed to the extent practicable at least thirty (30), but not more than
ninety (90) days prior to the date therein specified. In the event that the Company at any time
sends any other notice to the holders of its Common Stock, it shall concurrently send a copy of
such notice to each Holder of a Warrant.

             8.2 Taking of Record.

          In the case of all dividends or other distributions by the Company to the holders of its
Common Stock with respect to which any provision of any Section hereof refers to the taking of a
record of such holders, the Company will in each such case take such a record and will take such
record as of the close of business on a Business Day.

             8.3 Closing of Transfer Books.

          The Company shall not at any time, except upon dissolution, liquidation or winding up of
the Company, close its stock transfer books or Warrant transfer books so as to result in
preventing or delaying the exercise or transfer of any Warrant.

16

 

9. TRANSFER RESTRICTIONS; LEGENDS

          9.1 Restrictions on Transfer and Entry into Shareholders Agreement and Registration
Rights Agreement.

          Concurrently with the execution and delivery of this Agreement, each Holder of an Original
Warrant is entering into and becoming a party to each of the Shareholders Agreement and the
Registration Rights Agreement, if not already a party thereto, by completing and executing a
signature page thereof. The Company shall not be obligated to register any transfer of Warrants and
no such purported transfer shall be effective unless and until the transferee has executed and
delivered a joinder agreement pursuant to which such assignee becomes a party to the Shareholders
Agreement and the Registration Rights Agreement.

          9.2 Legends.

          (a) Each Warrant Certificate shall be stamped or otherwise imprinted with a legend in
substantially the following form:

     (i) “NEITHER THE WARRANTS REPRESENTED BY THIS
CERTIFICATE NOR ANY OF THE SECURITIES ISSUABLE UPON EXERCISE THEREOF HAVE BEEN
REGISTERED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, AND NEITHER THE WARRANTS REPRESENTED BY THIS CERTIFICATE NOR
ANY OF THE SECURITIES ISSUABLE UPON EXERCISE THEREOF MAY BE TRANSFERRED, SOLD,
PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS SUCH DISPOSITION IS PURSUANT
TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
AND ANY APPLICABLE STATE SECURITIES LAWS, OR IS MADE IN A TRANSACTION EXEMPT FROM
SUCH REGISTRATION REQUIREMENTS.”

     (ii) “THE WARRANTS REPRESENTED BY THIS CERTIFICATE
ARE SUBJECT TO THE PROVISIONS OF A WARRANT AGREEMENT, DATED AS OF DECEMBER 19, 2007,
A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.”

     (iii) “THE TRANSFER, SALE, ASSIGNMENT, PLEDGE OR

DATED AS OF DECEMBER 19, 2007, AS AMENDED AND MODIFIED FROM TIME TO TIME, AMONG XSTREAM SYSTEMS,
INC. (THE “COMPANY”) AND CERTAIN SECURITYHOLDERS, AND THE COMPANY RESERVES THE RIGHT TO REFUSE THE
TRANSFER OF SUCH SECURITIES UNTIL SUCH
CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO SUCH

17

 

TRANSFER. A COPY OF SUCH AMENDED AND RESTATED SECURITYHOLDERS AGREEMENT SHALL BE
FURNISHED BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT
CHARGE.”

          (b) Each certificate for shares of Warrant Stock shall be stamped or otherwise imprinted with
a legend in substantially the following form:

     (i) “THE SECURITIES REPRESENTED BY THIS CERTIFICATE
HAVE NOT BEEN REGISTERED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED, SOLD, PLEDGED,
HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS SUCH DISPOSITION IS PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND

SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO SUCH TRANSFER.
A COPY OF SUCH AMENDED AND RESTATED SECURITYHOLDERS AGREEMENT SHALL BE FURNISHED BY
THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE.”

          (c) In addition, Warrant Certificates and any certificates for shares of Warrant Stock shall
bear any legends required by applicable state law. When any Warrants or shares of Warrant Stock
have been registered under the Securities Act, and such Warrants or shares of Warrant Stock have
been sold pursuant to such registration or pursuant to Rule 144 under the Securities Act or are
eligible to be sold pursuant to paragraph (k) of such Rule, the Holder of such Warrants or shares
of Warrant Stock shall be entitled to exchange, as the case may be, the Warrant Certificate
representing such Warrants for a Warrant Certificate, or a certificate representing such shares of
Warrant Stock for a new certificate, in each case not bearing the legend required by clause (a)(i)
or (b)(i), as the case may be, of this Section 9. If any Warrants or shares of Warrant Stock cease
to be subject to this Agreement or the Shareholders Agreement, as the case may be, the Holder of
such Warrants or Warrant Stock shall be entitled to exchange,
as the case may be, the Warrant Certificate representing such Warrants for a Warrant
Certificate, or a certificate representing such shares of Warrant Stock for a new certificate, in
each case not

18

 

bearing the legend required by clauses (a)(ii), (a)(iii) or (b)(ii), as the case may be, of
this Section 9. Each Holder agrees that, in addition to complying with the restrictions on transfer
set forth elsewhere in this Agreement, such Holder will not directly or indirectly Transfer any
Warrants (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of any
Warrants) in violation of the Securities Act, applicable state securities or “blue sky” laws or any
rules or regulations thereunder, and such Holder will not Transfer any Warrants unless the
conditions set forth in the legend required by clause (a)(i) of this Section 9. are satisfied.

10. LOSS OR MUTILATION

          Upon receipt by the Company from any Holder of evidence reasonably satisfactory to it of the
ownership of and the loss, theft, destruction or mutilation of a Warrant Certificate and an
indemnity reasonably satisfactory to it (it being understood that the written indemnification
agreement of or affidavit of loss of a Holder of an Original Warrant shall be a sufficient
indemnity) and, in case of mutilation, upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder; provided,
however, in the case of mutilation, no indemnity shall be required if a Warrant Certificate in
identifiable form is surrendered to the Company for cancellation.

11. OFFICE OF THE COMPANY

          As long as any of the Warrants remain outstanding, the Company shall maintain an office or
agency, which may be the principal executive offices of the Company (the “Designated Office”),
where the Warrants may be presented for exercise, registration of transfer, division or combination
as provided in this Agreement. Such Designated Office shall initially be the office of the Company
at 10305 102nd Terrace, Suite 101, Sebastian, Florida 32958. The Company may from time
to time change the Designated Office to another office of the Company or its agent within the
United States by notice given to all registered holders of Warrants at least ten (10) Business Days
prior to the effective date of such change.

12. FINANCIAL AND BUSINESS INFORMATION

          (a) Until the applicable Exercise Date with respect to a Warrant, the Company shall
deliver to the Holder of such Warrant one copy of each of the following items:

     (i) as soon as available but in any event within 30 days after the end

Securities; and

          WHEREAS, the execution and delivery of this Agreement is a condition to the obligations of the

Agreement or (ii) to any Permitted Transferee. Any Transfer made or attempted in violation
of this Agreement shall be null and void.

          (b) Notwithstanding anything to the contrary contained in this Agreement, no Management
Shareholder shall Transfer any of such Management Shareholder’s Securities other than to a
Permitted Transferee until March 14, 2012.

          (c) Each Securityholder agrees not to, directly or indirectly, Transfer any of such
Securityholder’s Securities to any Person whose activities, products or services directly
compete with the activities, products or services of the Corporation as reasonably
determined in good faith by the Board as of the date of such proposed Transfer; provided
that the foregoing limitation shall not apply to Transfers registered under the Securities
Act or Rule 144 promulgated thereunder. The Corporation may impose stop transfer
instructions with its transfer agent in order to enforce the foregoing limitation.

          2.2 Holdback. Each Securityholder agrees not to effect any public sale or
distribution (including sales pursuant to Rule 144 promulgated under the Securities Act (as
such rule may be amended from time to time) of Securities, or any securities, options or

pledge, contract to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or
dispose of, directly or indirectly, any Securities, or any securities, options or rights

(such period not to exceed 180 days), except as part of such offering and unless the

the standard lock-up agreement of the underwriters managing such offering reflecting the
foregoing. In order to enforce the foregoing, the Corporation may impose stop-transfer
instructions with respect to the Securities of each Securityholder until the end of such
period.

7

 

          2.3 Transferees Required to Execute this Agreement. With respect to any Transfer

ARTICLE III

RIGHT OF FIRST REFUSAL AND CO-SALE RIGHT

ON PROPOSED TRANSFERS OF SECURITIES

          3.1 Right of First Refusal. Each Securityholder hereby grants to (a) each Preferred
Shareholder and (b) the Corporation a right of first refusal (a “Right of First Refusal”) to
purchase any or all Securities which such Securityholder (the “Selling Securityholder”) may, from
time to time, propose to Transfer (other than with respect to a Transfer to a Permitted
Transferee).

          3.2
Procedure. (a) In the event a Selling Securityholder wishes to make a Transfer of
Securities (other than with respect to a Transfer to a Permitted Transferee), the Selling
Securityholder shall deliver written notice (the “Transfer Notice”) to the Corporation specifying,
in reasonable detail, (i) its bona fide intention to Transfer such Securities, (ii) the type of
Securities to be Transferred, (iii) the number of such Securities to be Transferred, (iv) the
proposed price per security therefor and material terms and conditions upon which the proposed
Transfer is to be made, (v) the identity of each of the proposed Transferees and (vi) all other
information reasonably necessary or requested by the Corporation to fully describe and confirm the
bona fide nature of the proposed Transfer. As soon as practicable after the receipt of the Transfer
Notice, the Corporation shall distribute such Transfer Notice to each Preferred Shareholder (or, in
the case of a Selling Securityholder that is a Preferred Shareholder, to each other Preferred
Shareholder) (the “Non-Selling Securityholders”). Each Non-Selling Securityholder shall have 15
days from the date of the receipt of the Transfer Notice to exercise its Right of First Refusal to
purchase such Non-Selling Securityholder’s respective Pro Rata Share (but not less than such
Non-Selling Securityholder’s Pro Rata Share) of the Securities subject to the Transfer Notice (for
the price and upon the terms specified therein). If any Non-Selling Securityholder elects to
purchase its respective Pro Rata Share, such Non-Selling Securityholder shall notify the
Corporation and the Selling Securityholder within the 15-day period referenced above by written
notice (the “Right of First Refusal Election Notice”).

          (b) If, after the expiration of the 15-day period referenced above, any Non-Selling
Securityholder has not exercised its Right of First Refusal to purchase its respective Pro Rata
Share, the Corporation shall, within 5 days of the expiration of such 15-day period, provide the
other Non-Selling Securityholders with written notice (the “Over-Allotment Notice”) indicating the
aggregate amount of Securities as to which all Non-Selling Securityholders shall not have exercised
their Rights of First Refusal. Each Non-Selling Securityholder who shall have elected to purchase
its full Pro Rata Share of the Securities proposed to be Transferred by the Selling Securityholder
shall have 10 days upon receipt of the Over-Allotment Notice to give notice (the “Over-Allotment
Election Notice”) to the Corporation and the Selling Securityholder whether it elects to exercise
its Over-Allotment Option granted in Section 3.3.

8

 

          (c) If, after expiration of the additional 10-day period referenced in Section 3.2(b),
the Non-Selling Securityholders in the aggregate have elected not to purchase all of the Securities
subject to the Transfer Notice, then the Corporation shall have 10 days from the expiration of such
additional 10-day period to purchase any or all of the Securities subject to the Transfer Notice
and not purchased by the Non-Selling Securityholders by delivering written notice to the Selling
Securityholder.

          (d) If the Corporation or any Non-Selling Securityholder shall have failed to deliver to the
Selling Securityholder or the Corporation written notice with respect to its Right of First Refusal
within the time periods described in this Section 3.2, it shall be deemed to have waived the rights
described herein.

          (e) Settlement for the Securities to be purchased by either the Corporation or any Non-Selling
Securityholder pursuant to this Section 3.2 shall be made in cash within 50 days from the
Corporation’s deemed date of receipt of the Transfer Notice; provided, however, that if the terms
of payment for the Securities specified in the Transfer Notice were for other than cash against
delivery, each of the Corporation and the Non-Selling Securityholders may pay to the Selling
Securityholder the fair market value of such consideration (as determined in good faith by the
Board) in cash.

          3.3 Over-Allotment Option. In the event that the Non-Selling Securityholders in the
aggregate do not purchase all of the Securities offered by the Selling Securityholder pursuant to
the Right of First Refusal described in this Article III, then any Non-Selling
Securityholder that shall have exercised its Right of First Refusal to purchase its full Pro Rata
Share of such Securities shall also have the right (the “Over-Allotment Option”) to purchase up to
all of its respective pro rata share among such Non-Selling Securityholders (or such other
proportion as may be agreed to by all of the Non-Selling Securityholders that have exercised their
Rights of First Refusal) of the remaining Securities (the “Over-Allotment Option Securities”)
offered in accordance with this Section 3.3, in addition to such Securities it has already elected
to purchase, as provided in Section 3.2(b).

          3.4 Co-Sale Rights, (a) If, after the expiration of the 40-day period beginning on the
Corporation’s deemed receipt of the Transfer Notice (the “Offer Period”), the Corporation and the
Non-Selling Securityholders have not elected to purchase, in aggregate, all of the Securities
subject to the Transfer Notice, then each of the Non-Selling Securityholders shall have a co-sale
right (a “Co-Sale Right”) to sell, upon the terms and conditions contained in the applicable
Transfer Notice and in accordance with the procedures set forth in this Section 3.4 (it
being understood that, if more than one class or type of Securities is to be sold, the relative
prices of such Securities shall be determined as provided in Section 3.4(d)), to the
proposed Transferee up to that number of Securities of the same class or type proposed to be
Transferred equal to its Co-Sale Pro Rata Share (as defined below); provided, however, that if the
Selling Securityholder is Transferring Common Stock, each of the Non-Selling Securityholders may
sell shares of Preferred Stock (the number of which shall be determined on an as-converted basis)
to the proposed Transferee; provided further that notwithstanding the immediately preceding
proviso, in the event that a Non-Selling Securityholder that wishes to exercise its Co-Sale right
holds Securities of the same class or type proposed to be Transferred by the Selling
Securityholder,

9

 

such Non-Selling Securityholder must sell such Securities to the proposed Transferee prior to
selling Securities of any other class or type to the proposed Transferee.

          (b) Each Non-Selling Securityholder shall have 15 days from the expiration of the Offer Period
(the “Co-Sale Period”) to exercise its Co-Sale Right as provided in this Section 3.4 by
delivering written notice (the “Co-Sale Election Notice”) to the Selling Securityholder, with a
copy to the Corporation. The Co-Sale Election Notice shall specify the number of Securities that
such Non-Selling Securityholder elects to sell (up to such Co-Sale Pro Rata Share). A Non-Selling
Securityholder’s failure to deliver a Co-Sale Election Notice with respect to such Securities
within such 15-day period shall be deemed a waiver of its Co-Sale Right with respect to the
proposed Transfer.

          (c) If a prospective Transferee refuses to purchase Securities from a Non-Selling
Securityholder exercising its Co-Sale Right hereunder, the Selling Securityholder shall not sell
any Securities to such prospective Transferee unless and until, simultaneously with such sale, the
Selling Securityholder shall purchase such Securities from the Non-Selling Securityholder for the
same consideration (or cash equal to the fair market value thereof as determined in good faith by a
majority of the Board) and on the same terms and conditions as the proposed Transfer described in
the Transfer Notice.

          (d) In the event that a Non-Selling Securityholder has delivered a Co-Sale Election Notice
with respect to Securities that are of a class or type other than the class or type being sold by
the Selling Securityholder to the proposed Transferee, the price per share to be paid by the
proposed Transferee for such Non-Selling Securityholder’s Securities shall be determined in good
faith by a majority of the Board and shall be equal on a relative basis to the price per share
being paid by the proposed Transferee for the Selling Securityholder’s Securities, taking into
account the relative rights and privileges of the respective classes of Securities.

          (e) Each Non-Selling Securityholder’s “Co-Sale
Pro Rata Share” with respect to any proposed
Transfer is that number of Securities equal to the product obtained
by multiplying  (i) the
aggregate number of shares of Common Stock (calculated on a Fully-Diluted Basis) subject to the
Transfer Notice by (ii) a fraction, (x) the numerator of which is the number of shares of Common
Stock (calculated on a Fully-Diluted Basis) then held by such Non-Selling Securityholder and (y)
the denominator of which is the total number of shares of Common Stock then outstanding (calculated
on a Fully-Diluted Basis).

          3.5 Transfer of Securities upon Failure to Exercise Right of First Refusal or
Co-Sale Right. The Selling Securityholder may, during the 60-day period following the
expiration of the Co-Sale Period, conclude a Transfer of any or all of the Securities covered by
the Transfer Notice and not otherwise subject to the Right of First Refusal or Co-Sale Right, on
terms and conditions the same or the same in all material respects as those described in the
Transfer Notice; provided, however, that if the Selling Securityholder fails to consummate the
proposed Transfer described in the Transfer Notice during the 60-day period following the
expiration of the Co-Sale Period, or if a proposed Transfer is to be consummated on terms that are
not the same in all material respects as those disclosed in the Transfer Notice or with a proposed
Transferee other than that identified in the Transfer Notice, then the Selling

10

 

Securityholder shall be required to comply anew with the requirements of this Article III
prior to consummating the proposed Transfer.

ARTICLE IV

DRAG-ALONG OBLIGATIONS

          4.1 Drag-Along Obligations of Securityholders. (a) For so long as the Investors own
(or would own after giving effect to all of the transactions contemplated by the Purchase
Agreement) at least 20% of the outstanding Securities (on a Fully-Diluted Basis), if the Board
(including a majority of the Investor Directors (as defined in Section 6.1(b)) and a
majority of the holders of outstanding shares of Common Stock and Preferred Stock (voting on a
Common Stock equivalent basis) approve a Sale of the Corporation (an “Approved Sale”), then each
Securityholder covenants and agrees to vote for, consent to and raise no objections against such
Approved Sale. If the Approved Sale is structured as a (x) merger or consolidation, each
Securityholder covenants and agrees to waive any dissenters’ rights, appraisal rights or similar
rights in connection with such merger or consolidation, (y) sale of Securities, each
Securityholder covenants and agrees to sell all of his, her or its Securities and rights to
acquire Securities on the terms and conditions so approved or (z) sale of all or substantially
all of the assets of the Corporation, each Securityholder covenants and agrees to approve any
subsequent liquidation of the Corporation in connection therewith. In addition, each
Securityholder covenants and agrees to take all necessary or desirable actions in connection with
the consummation of the Approved Sale as requested by the Board.

          (b) Conditions to Drag-Along Obligations. The obligations of the
Securityholders described in Section 4.1 (a) with respect to an Approved Sale are subject
to the satisfaction of the following conditions: (i) upon the consummation of the Approved Sale,
each Securityholder shall receive the same portion of the aggregate consideration that such
Securityholder would have received if such aggregate consideration had been distributed by the
Corporation in complete liquidation pursuant to the rights and preferences set forth in the
Corporation’s Certificate of Incorporation as in effect immediately prior to such Approved Sale
(giving effect to applicable orders of priority); and (ii) upon the consummation of any such
Approved Sale, all of the Securityholders of a particular class of Securities shall receive (or
shall have the option to receive) the same form of consideration.

          4.2
Indemnification in Approved Sale. (a) In connection with any Approved Sale, the
Securityholders shall be obligated to join on a pro rata basis (based on each such
Securityholder’s share of the aggregate proceeds paid with respect to its equity interest in the
Corporation) in any indemnification obligation agreed to in connection with such Approved Sale
(other than any such obligations that relate specifically to a particular Securityholder such as
indemnification with respect to representations and warranties given by a Securityholder
regarding such Securityholder’s title to and ownership of Securities); provided, that: (x) no
such Securityholder shall be obligated in connection with such Approved Sale to indemnify the
prospective Transferee or its Affiliates with respect to an amount in excess of the net cash
proceeds paid to such Securityholder in connection with such Approved Sale; (y) any escrow of
proceeds of any such transaction shall be withheld on a pro rata basis among all Securityholders;
and (z) each such Securityholder shall pay its pro rata share of the expenses incurred by the
Securityholders in connection with such Approved Sale.

11

 

          (b) Notwithstanding anything contained in this Agreement, in no event will any Securityholder
be required to make any representations or warranties in connection with an Approved Sale that are
joint and several with any other Securityholder(s) or that pertain to
matters other than title to the Common Stock or other securities held by such
Securityholder, such Securityholder’s capacity, authority or power to consummate or
participate in the transaction in question and other matters peculiar to such
Securityholder and customary for the type of transaction being consummated.

ARTICLE V

PREEMPTIVE RIGHTS

          5.1 Preemptive Rights. (a) If the Corporation proposes to issue or sell
any New Securities (as defined in this Section 5.1) after the date hereof, the
Corporation shall notify in writing each Preferred Shareholder (each a “Preemptive Right
Holder”) of such proposed transaction (the “Preemptive Right Notice”). The Preemptive
Right Notice shall describe the proposed issuance or sale, identify the proposed buyer and
contain an offer to sell to each Preemptive Right Holder, at the same price and for the
same consideration (subject to the last sentence of this paragraph) to be paid by the
proposed buyer, additional New Securities of the same class and type being offered to the
proposed buyer in an amount equal to the product obtained by multiplying (i) the
number of New Securities being offered to the proposed buyer
by (ii) a fraction,
(x) the numerator of which is the number of shares of Preferred Stock and Conversion
Common Shares held by such Preemptive Right Holder (calculated on a Fully-Diluted Basis)
and (y) the denominator of which is the total number of shares of Preferred Stock and
Conversion Common Shares then outstanding (on a Fully-Diluted Basis). If the purchase
price for the New Securities to be paid by the proposed buyer is in some form other than
cash, then a Preemptive Right Holder may pay for the additional New Securities it is
entitled to purchase hereunder in cash (with the fair market value of any non-cash
consideration to be paid by such buyer to be determined in good faith by the Board). A
Preemptive Right Holder shall have 15 days from the receipt of a Preemptive Right Notice
to accept the offer contained in such Preemptive Right Notice, and any purchase of New
Securities by a Preemptive Right Holder shall be made within 30 days of receipt of the
Preemptive Right Notice by such Preemptive Right Holder.

          (b) If any Preemptive Right Holder fails to accept the offer contained in the
Preemptive Right Notice within 15 days after the receipt thereof, the Corporation shall be
entitled to sell such New Securities free of any right on the part of such Preemptive
Right Holder under this Section 5.1 during the 180 days following such 15-day
period at a price not less than, and on other terms and conditions not more favorable
than, that offered to such Secondary Preemptive Right Holder. Any New Securities offered
or sold by the Corporation after such
180-day period must be reoffered to all Preemptive Right Holders, in accordance with the
terms of this Section 5.1.

          (c) Except as set forth in the immediately following sentence, “New Securities” shall
mean any shares of capital stock of the Corporation, including Common Stock and preferred
stock (including Preferred Stock), whether or not now authorized, and rights, options or
warrants to purchase shares of Common Stock or preferred stock (including Preferred Stock)
and securities of any type whatsoever that are, or may by their terms become, convertible into or

12

 

exchangeable for shares of Common Stock or preferred stock. Notwithstanding the foregoing, “New
Securities” shall not include the following:

     (i) shares of Common Stock issued upon the conversion of the
Preferred Stock;

     (ii) the Warrants or any shares of Common Stock issued upon exercise of
the Warrants;

     (iii) shares of Common Stock issued upon the exercise of Options or other
Convertible Securities outstanding as of March 14, 2007;

     (iv) securities issued pursuant to a Board-approved (including at least
one of the Investor Directors) acquisition of an entity by merger, purchase of
substantially all of the assets or other reorganization;

granted under the Catalyst Letter Agreements;

     (vi) shares of Common Stock issued as a dividend or distribution on, or in
connection with a split of or recapitalization of, any of the capital stock of the
Corporation;

     (vii) up to an aggregate of 250,000 shares of Common Stock reserved for
issuance per year pursuant to the Option Plan (subject to adjustment in the event of
stock splits, stock dividends, stock combinations, recapitalizations and like
occurrences) and shares of Common Stock reserved for issuance pursuant to the Option
Plan in lieu of the repayment of certain salary deferrals as approved by a majority
of the Board (including at least one of the Investor Directors), which foregoing
shares may be subject to Options or restricted stock awards granted under the Option
Plan; provided that any Options that expire or terminate unexercised or any
restricted stock awards that are repurchased by the Corporation pursuant to the
terms of such award shall not be counted toward the maximum number set forth in this
subparagraph (vii) unless and until such shares are subject to new restricted stock
awards (or new Options) pursuant to the terms of the Option Plan;

     (viii) shares of Common Stock issued or issuable (including pursuant to
Options) to suppliers or third-party service providers in connection with the
provision of goods or services pursuant to transactions in the ordinary course of

          7.2 Restrictions on Other Agreements. No Securityholder shall enter into any
shareholder agreement or other arrangements of any kind with any Person with respect to the
Securities on terms inconsistent with the provisions of this Agreement (whether or not such
agreements and arrangements are with other Securityholders), including agreements or arrangements
with respect to the acquisition, disposition or voting of Securities.

          7.3 Specific Enforcement. Each Securityholder expressly agrees that the other
Securityholders will be irreparably damaged if this Agreement is not specifically enforced. Upon a
breach or threatened breach of the terms, covenants or conditions of this Agreement by any

entitled to a temporary or permanent injunction, without showing any actual damage, and/or a decree
for specific performance, in accordance with the provisions hereof.

          7.4 Legend. Each certificate or instrument representing any of the Securities shall
bear a legend in substantially the following form:

“THE TRANSFER, SALE, ASSIGNMENT, PLEDGE OR OTHER DISPOSITION OF THE SECURITIES
REPRESENTED BY THIS CERTIFICATE IS RESTRICTED BY AND SUBJECT TO THE TERMS AND
CONDITIONS SPECIFIED IN THAT CERTAIN AMENDED AND RESTATED SECURITYHOLDERS AGREEMENT,
DATED AS OF DECEMBER 19, 2007, AS AMENDED AND MODIFIED FROM TIME TO TIME, AMONG
XSTREAM SYSTEMS, INC. (THE “COMPANY”) AND CERTAIN SECURITYHOLDERS, AND THE COMPANY
RESERVES THE RIGHT TO REFUSE THE TRANSFER OF SUCH SECURITIES UNTIL SUCH CONDITIONS
HAVE BEEN FULFILLED WITH RESPECT TO SUCH

16

 

TRANSFER. A COPY OF SUCH AMENDED AND RESTATED SECURITYHOLDERS AGREEMENT SHALL BE
FURNISHED BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT
CHARGE.”

          7.5 Confidentiality, (a) Each Securityholder agrees to keep all Confidential
Information (as defined below) confidential and not use or disclose such information to others
during the term of this Agreement and at all times thereafter, except (i) to such
Securityholder’s attorneys, accountants or financial advisors, provided that, prior to any such
disclosure, such Securityholder has delivered written notice to such attorneys, accountants and
financial advisors that the information is subject to prohibitions upon use or disclosure
pursuant to the terms of this Agreement, and provides the Company concurrently with a copy of
each such notice or (ii) as required by law. In the event any Securityholder is no longer a
securityholder of the Company, such securityholder shall neither take nor retain, without prior
written authorization from the Company, any other Confidential Information, or copies thereof,
of any kind belonging to the Company. Without limiting other possible rights or remedies to the
Company for such Securityholder’s breach of this covenant, each Securityholder acknowledges and
agrees that injunctive or other equitable relief shall be available to the Company to enforce
this covenant, without having to post a bond, cash or otherwise.

          (b) “Confidential Information” means and shall include any and all of the following: (i)
the parties to this Agreement; (ii) the respective ownership or other economic interest that
each Securityholder has with respect to the Company; and (iii) all trade secrets, know-how, and
all information concerning the business and affairs of the Company and its Subsidiaries
(including historical financial statements, financial projections and budgets, historical and
projected sales, capital spending budgets and client data and information), however documented,
that has been or may hereafter be provided or shown to a Securityholder by the Company or by the
directors, officers, employees, agents, consultants, advisors or other representatives,
including legal counsel, accountants and financial advisors, of the Company. Confidential
Information does not include information which (i) is in the public domain; (ii) is received by
a Securityholder outside of the Securityholder’s relationship with the Company or any of its
Subsidiaries from a party not directly or indirectly under an obligation of confidentiality to
the Company or its Subsidiaries; (iii) later becomes public, unless such information is made
public by the Securityholder in breach of this Agreement or by any other party directly or
indirectly under an obligation of confidentiality to the Company or its Subsidiaries; or (iv)
which a Securityholder is required to disclose by or to any court of competent jurisdiction or
any other governmental or quasi-governmental agency, authority or instrumentality of competent
jurisdiction; provided, that such Securityholder shall, prior to any such disclosure,
immediately notify the Company or the Securityholder to which the information required to be
disclosed relates of such requirement in order to allow the Company or such affected
Securityholder a reasonable opportunity to seek protective measures of such Confidential
Information.

          7.6 Notices. Any notices required or permitted to be sent hereunder to a
Securityholder shall be delivered personally, transmitted by fax, mailed via certified mail
(return receipt requested) or delivered by overnight courier service to the address set forth on the
stock

17

 

	 	 	

record books of the Corporation, or such other address as shall be given by notice delivered

mailed, or one business day after delivery to the courier if delivered by overnight courier
service. Any notices to the Corporation shall be sent to the following:

          7.7 Entire Agreement. This Agreement constitutes the entire agreement
of the parties with respect to the subject matter hereof and supersedes all prior
agreements, arrangements and understandings between or among the parties hereto (whether
written or oral), including that certain Stockholders Agreement, dated as of October 7,
2004, among the Company, the Investors named therein and Brian Mayo, and the Original
Shareholders Agreement.

          7.8 Governing Law. This Agreement shall be governed by the laws of the State
of Delaware without regard to the choice of law provisions of such State or any other
State.

          7.9 Successors and Assigns. This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective heirs, executors, legal
representatives, successors and Permitted Transferees.

          7.10 Further Assurances. The parties hereto agree, upon the reasonable
request of the Board, to execute any further documents or instruments necessary or
desirable to carry out the purposes or intent of this Agreement.

          7.11 Amendments and Waivers. The provisions of this Agreement may be amended
or waived at any time only by the written agreement of (i) the Corporation and (ii) the
holders of a majority of the shares of Common Stock (on a Fully-Diluted Basis) held by the
Securityholders party hereto, including a majority of the Conversion Common Shares, acting
separately as a single class on a Fully-Diluted Basis, provided that if a proposed waiver
or amendment would treat any Securityholder in respect of such Securityholder’s Securities
differently from the other Securityholders holding the same Securities, then the consent
of such Securityholder shall be required to effect any such waiver or amendment. Any
waiver, permit, consent or approval of any kind or character on the part of any such
holders of any provision or condition of this Agreement must be made in writing and shall
be effective only to the extent specifically set forth in writing. The failure of any
party hereto to enforce at any time any provision of this Agreement shall not be construed
to be a waiver of such provision, nor in any way to affect the validity of this Agreement
or any part hereof or the right of any party hereafter to enforce each and every such
provision. No waiver of any breach of this Agreement shall be
held to constitute a waiver of any other or subsequent breach.

18

 

          7.12 Addition of Securityholders. As requested by the Corporation, this Agreement
shall be binding upon additional securityholders upon the acquisition by them of capital stock of
the Corporation, and upon execution of a Joinder by the additional Securityholder and the
Corporation, as if all such signatories were original signatories to this Agreement, as
Securityholders.

          7.13 Severability. If any provision of this Agreement shall be held to be illegal,
invalid or unenforceable, such illegality, invalidity or unenforceability shall attach only to such
provision and shall not in any manner affect or render illegal, invalid or unenforceable any other
provision of this Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

          7.14 Counterparts. This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

          7.15 Interpretation. For purposes of this Agreement, (i) the words “include,”
“includes” and “including” shall be deemed to be followed by the words “without limitation,” (ii)
the word “or” is not exclusive and (iii) the words “herein,” “hereof,” “hereby,” “hereto” and
“hereunder” refer to this Agreement as a whole. Unless the context otherwise requires, references
herein: (i) to an agreement, instrument or other document means such agreement, instrument or other
document as amended, supplemented and modified from time to time to the extent permitted by the
provisions thereof and by this Agreement; and (ii) to a statute means such statute as amended from
time to time and includes any successor legislation thereto and any regulations promulgated
thereunder. Titles to Articles and headings of Sections are inserted for convenience of reference
only and shall not be deemed a part of or to affect the meaning or interpretation of this
Agreement. This Agreement shall be construed without regard to any presumption or rule requiring
construction or interpretation against the party drafting an instrument or causing any instrument
to be drafted.

          7.16 Delivery by Facsimile. This Agreement, to the extent signed and delivered by
means of a facsimile machine, shall be treated in all manner and respects as an original agreement
or instrument and shall be considered to have the same binding legal effect as if it were the
original signed version thereof delivered in person. At the request of any party, each other party
shall reexecute original forms thereof and deliver them to all other parties. No party shall raise
the use of a facsimile machine to deliver a signature or the fact that any signature or agreement
or instrument was transmitted or communicated through the use of a facsimile machine as a defense
to the formation or enforceability of a contract and each such party forever waives any such
defense.

          7.17 Failure to Deliver Securities. If any Securityholder who has become obligated to
sell Securities hereunder shall fail to deliver such Securities to the Corporation in accordance
with the terms of this Agreement, the Corporation may, at its option, send to such Securityholder
by registered mail, return receipt requested, the consideration for such Securities as is herein
specified. Thereupon, the Corporation shall (i) cancel on its books the certificate or certificates
in the name of the Corporation representing such Securities and (ii) issue, in lieu
thereof, a new certificate or certificates in the name of the Corporation representing such

19

 

Securities, and thereupon all of such Securityholder’s rights in and to such Securities
shall terminate, subject to any previously asserted and outstanding claim by such Securityholder.

EXECUTION COPY

FIRST AMENDMENT TO REGISTRATION RIGHTS AGREEMENT

          THIS FIRST AMENDMENT TO REGISTRATION RIGHTS AGREEMENT (this “Amendment”) is entered into as of this
19th day of December, 2007 by and among XStream Systems, Inc., a Delaware corporation
(the “Company”), and the Persons named on Schedule I attached hereto as Investors (individually an
“Investor” and collectively the “Investors”).

RECITALS

          WHEREAS, pursuant to a Series A Preferred Stock Purchase Agreement dated as of March 14, 2007 (the
 “Original Purchase Agreement”) among the Company and certain of the Investors (collectively, the
“First Round Investors”), the First Round Investors have purchased shares of the Company’s Series A
Redeemable Convertible Preferred Stock, $.0001 par value per share (the “Series A Preferred
Stock”);

          WHEREAS, pursuant to a First Amendment dated as of December 19, 2007 to the Original Purchase
Agreement (the “First Amendment”) among the Company and certain of the Investors (collectively, the
“Second Round Investors”), (i) the Second Round Investors have purchased shares of the Company’s
Series B Redeemable Convertible Preferred Stock, $.0001 par value per share (the “Series B
Preferred Stock”), together with warrants (the “Series B Warrants”) to purchase shares of the
Company’s Common Stock, $.0001 par value per share (the “Common Stock”) and (ii) certain of the
Second Round investors have the option to purchase shares of the Company’s Series C Redeemable
Convertible Preferred Stock, $.0001 par value per share (the “Series C Preferred Stock”), together
with warrants (the “Series C Warrants”) to purchase shares of the Company’s Common Stock;

          WHEREAS, the First Round Investors and the Company are parties to a Registration Rights Agreement
dated as of March 14, 2007 (the “Registration Rights Agreement”), which they desire to amend, among
other things, to allow the Second Round Investors who are not already parties to the Registration
Rights Agreement to become parties, to include the Series B Preferred Stock and the Series B
Warrants as “Registrable Securities” and to include the Series C Preferred Stock and the Series C
Warrants as “Registrable Securities,” if such stock and warrants are issued;

          WHEREAS, the execution and delivery of this Amendment is a condition to the obligations of the
Second Round Investors under the First Amendment.

          NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained
herein, and for other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto hereby agree as follows:

     1. Amendments to the Registration Rights Agreement.

     (a) Section 10 of the Registration Rights Agreement shall be amended as follows:

1

 

     (i) to delete the existing definition of the term “Additional Preferred Stock.”

     (ii) to amend the existing definitions of the terms “Preferred Stock,” “Purchase Agreement,”
“Registrable Securities” and “Shareholders Agreement” to read in their entirety as follows:

     “Preferred Stock” means the Company’s (i) Series A Redeemable Convertible Preferred Stock, $.0001
par value per share, (ii) Series B Redeemable Convertible Preferred Stock, $.0001 par value per
share and (iii) Series C Redeemable Convertible Preferred Stock, $.0001 par value per share.

     “Purchase Agreement” means the Series A Preferred Stock Purchase Agreement dated as of March 14,
2007, as amended, among the Company and certain of the Investors (as the same may be amended,
modified, restated or replaced).

     “Registrable Securities” means (i) any Common Stock issued or issuable upon the conversion or
redemption of the Preferred Stock or any Warrants, (ii) any Common Stock issued or issuable
directly or indirectly with respect to the securities referred to in clause (i) by way of stock
dividend, stock conversion or stock split or in connection with a combination of shares,
recapitalization, merger, consolidation or other reorganization and (iii) any other shares of
Common Stock held by Persons holding securities described in clause (i). As to any particular
Registrable Securities, such securities shall cease to be Registrable Securities (x) when they have
been distributed to the public pursuant to an offering registered under the Securities Act, (y)
when they have been sold to the public through a broker, dealer or market maker in compliance with
Rule 144 under the Securities Act (or any similar rule then in force) or (z) when they may be sold
without registration in compliance with Rule 144(k) under the Securities Act (or any similar rule
then in force). For purposes of this Agreement, a Person shall be deemed to be the holder of
Registrable Securities, and the Registrable Securities shall be deemed to be outstanding and in
existence, whenever such Person has the right to acquire such Registrable Securities upon
conversion of Preferred Stock, exercise of Warrants or conversion or exercise of any other
securities held by such Person, whether or not such acquisition has actually been effected, and
such Person shall be entitled to exercise the rights of a holder of such Registrable Securities
hereunder.

     “Shareholders Agreement” means the Amended and Restated Securityholders Agreement dated as of
December 19, 2007 by and among the Corporation and the securityholders of the Company named therein
(as the same may be amended, modified, restated or replaced).

2

 

     (iii) to add the definition of the term “Warrants” as follows:

     “Warrants” means the warrants to purchase Common Stock of the Company issued by the Company
pursuant to the Series B Warrant Agreement dated as of December 19, 2007 and the warrants to
purchase Common Stock of the Company to be issued by the Company pursuant to the Series C Warrant
Agreement dated as of December 19, 2007.

     (b) Section 11 (m) of the Registration Rights Agreement shall be amended to read in its entirety as
follows:

     (m) Assignment of Registration Rights. The rights to cause the Company to register
Registrable Securities pursuant to Sections 1 and 2 may be assigned (but only with
all related obligations) by a holder to a transferee or assignee of such Registrable Securities
that (i) is a Permitted Transferee (as defined in the Shareholders Agreement) of such holder or
(ii) after such assignment or transfer, holds at least 6,575 shares of Registrable Securities (as
adjusted to reflect stock splits, stock dividends, stock combinations, recapitalizations and like
occurrences); provided that (A) the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such transferee or assignee and
the Registrable Securities with respect to which such rights are being assigned and (B) such
transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of
this Agreement. For the purposes of determining the number of shares of Registrable Securities held
by a transferee or assignee, the holdings of a transferee or assignee (1) that is a subsidiary,
parent, partner, limited partner, retired partner, member, retired member or stockholder of a
holder, (2) that is an Affiliate of the holder, (3) who is a holder’s immediately family member or
(4) that is a trust for the benefit of an individual holder or such holder’s immediate family
member, shall be aggregate together and with those of the assigning holder; provided that
all transferees and assignees who would not qualify individually for assignment of registration
rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving
notices or taking any action under Sections 1 and 2. Notwithstanding the foregoing,
any transferee of a Warrant shall be entitled to, and shall become, a party to this Agreement as a
condition to the transfer of such Warrant and shall be considered an “Investor” and a holder of
Registrable Securities with the rights and obligations provided in this Agreement.

     (c) Section 11 (j) of the Registration Rights Agreement shall be amended to read in its entirety as
follows:

     All notices or other communications required or permitted hereunder shall be in writing and shall
be deemed given or delivered (a) when delivered personally, (b) if transmitted by facsimile when
confirmation of transmission is received, (c) if sent by registered or certified mail, postage
prepaid, return receipt requested, three business days after mailing or (d) if sent by reputable

executed counterpart of a signature page to this Amendment, whether manually executed or a

“hereof,” “hereby,” “hereto” and “hereunder” refer to this Amendment as a whole.

     (c) Unless the context otherwise requires, references herein to Sections, Exhibits and Schedules
mean the Sections of, and the Exhibits and Schedules attached to, this Amendment. Headings of
Sections are inserted for convenience of reference only and shall not be deemed a part of or to
affect the meaning or interpretation of this Amendment. The Schedules and Exhibits referred to
herein shall be construed with and as an integral part of this Amendment to the same extent as if
they were set forth verbatim herein.

     (d) Each of the parties to this Amendment has had the benefit of counsel in connection with its
review and negotiation of this Amendment. Consequently, the parties confirm that this Amendment
shall not be construed on the basis of any presumption or rule requiring construction or
interpretation against the party drafting an agreement or instrument or causing any agreement or
instrument to be drafted.

waive a condition specified in this Article III (a “Non-Participating
Investor”), the Company and the remaining Investors may elect to proceed with the
First Closing, the Second Closing or the Third Closing, as the case may be, with the

of such Investor’s (but not any other Investor’s) rights or remedies against the
Company for any claims or losses based solely on such waived condition not being
satisfied at the applicable Closing, but shall not constitute a waiver by such
Investor of any rights or remedies accruing to such Investor thereafter.

Ladies and Gentlemen:

     We

“Transaction Documents”); (2) Exhibit

     Furthermore, in rendering the opinions below, we have assumed, to the extent relevant to any
of our opinions expressed herein, the following matters to be true:

          (a) The execution, delivery and performance of the Transaction Documents by all parties
thereto (other than the Company) and the consummation by such parties of the transactions
contemplated by the Transaction Documents do not and will not conflict with or violate and will
not cause or result in a violation or breach of: (i) any statute, regulation or rule by which any
such party is bound or to which any such party is subject, or (ii) any contracts, instruments,
agreements, injunctions, orders or decrees by which any such party is bound;

          (b) All factual matters contained in the Transaction Documents are true and correct and are
not inconsistent with the opinions set forth in this letter;

          (c) No authorization, approval or consent of, or filing or registration with, any
governmental or regulatory body is required by any party to the Transaction Documents (other than
the Company) in connection with the execution, delivery or performance, or validity or
enforceability of the Transaction Documents;

          (d) There is proper consideration for the Company’s execution of the Transaction Documents;

          (e) The legal capacity of each natural person; the legal existence of all parties to the
Transaction Documents (other than the Company); the power and authority of each party to execute,
deliver and perform each document executed and delivered and to do each other act done or to be
done by such party; and the due authorization, execution and delivery by each party of each
document executed and delivered or to be executed and delivered by such party;

          (f) The validity, binding effect and enforceability as to each party, other than the Company,
of each Transaction Document executed and delivered or to be executed
and delivered and of each
other act done or to be done by such party;

          (g) There have been no undisclosed modifications of any provision of any document reviewed by
us in connection with the rendering of these opinions and no undisclosed prior waiver of any right
or remedy contained in any of the documents;

to the original of each document reviewed by us as a copy and the authenticity of the original of
each document received by us as a copy;

          (i) Each Purchaser has acted in good faith, without notice of adverse claims, and has
complied with all laws applicable to it that affect the transaction contemplated by the
Transaction Documents;

          (j) The transactions contemplated by the Transaction Documents comply with all tests of good
faith, fairness and conscionability required by law;

the Company in the future that might result in a violation of any statute, regulation or rule;

Documents that would modify the terms of the Transaction Documents or the respective rights or
obligations of the parties to those documents;

          (n) With respect to the transactions contemplated by the Transaction Documents, there has
been no mutual mistake of fact and there exists no fraud or duress; and

          (o) All documents incorporated by reference into, or referred to in the Transaction
Documents, which are not themselves Transaction Documents, are enforceable against the parties
thereto in accordance with their terms.

     Whenever in this letter our opinion, with respect to the existence or absence of facts, is
intended to be based on our knowledge or attention, it is intended to signify that during the
course of our representation of the Company, no information has come to the attention of those
attorneys in this law firm who have represented the Company in connection with the transactions
described in this opinion letter which gave those attorneys actual knowledge of the existence or
absence of those facts. Except to the extent expressly set forth in this letter, as noted above, we
have not undertaken any independent investigation to determine the existence or absence of any
facts material to our opinion, and no inference as to our knowledge of the existence or absence of
those facts should be drawn from our representation of the Company.

     Subject to the foregoing and the exclusions, assumptions and qualifications contained below,
we are of the opinion that:

Greenberg Traurig, P.A.

     1. Based solely on the Good Standing Certificate (as defined in Exhibit “B”), the Company is a
corporation, validly existing and in good standing under the laws of the State of Delaware. Based
solely on the Authority Certificate (as defined in Exhibit “B”), the Company is qualified as a
foreign corporation in the State of Florida.

     2. The Company has all requisite corporate power and authority to execute and deliver the
Transaction Documents, and to close the transactions contemplated thereby. All corporate action
required to be taken by the Company to authorize the execution and delivery of the Transaction
Documents and the closing of the transactions contemplated thereby, have been duly and properly
taken.

     3. Each of the Transaction Documents constitutes the valid and binding obligation of
the Company, enforceable against the Company in accordance with its terms.

     4. The execution and delivery of the Transaction Documents by the Company, and the closing of
the transactions contemplated thereby do not conflict with, or result
in any violation of or
default under, or give rise to a right of termination, cancellation or acceleration of any
obligation under, (i) any provision of the certificate of incorporation or bylaws of the Company,
as amended, or (ii) any statute, regulation or rule of the State of Delaware or the State of
Florida, which is applicable in our experience to transactions of the kind contemplated by the
Transaction Documents, or, to our knowledge, any injunction, order or decree of any executive,
legislative, judicial, administrative or regulatory body of the State of Delaware or the State of
Florida (collectively, a “Governmental Authority”) that is binding upon the Company.

     5. The shares of Series B Preferred Stock and the Series B Warrants underlying the Series B
Units, when issued in accordance with the provisions of the Amendment and upon receipt of all
consideration specified in the Amendment, will be validly issued, fully paid and nonassessable.

     6. The shares of common stock issuable upon exercise of the Series B Warrants, when issued in
accordance with the provisions of the Series B Warrant Agreement and upon receipt of all
consideration specified in the Series B Warrant Agreement, will be validly issued, fully paid and
nonassessable.

	 	 	The opinions expressed herein are subject in all respects to the following limitations and
qualifications:

          (i) We express no opinion whatsoever as to the effect of bankruptcy, reorganization,
insolvency, fraudulent conveyance, fraudulent transfer, moratorium and other similar laws or
equitable principles affecting creditors’ rights and remedies generally or general principles of
equity (including, without limitation, concepts of conscionability, materiality,

reasonableness, good faith and fair dealing) on the enforceability of the Transaction Documents
regardless of whether considered in a proceeding at law or in equity.

          (ii) This opinion letter is limited to the laws of the States of Delaware and Florida. We
give no opinion with respect to any provision specifying that the law of a particular state is to
apply, and we assume that the Transaction Documents are governed by the laws of the States of
Delaware or Florida.

     Notwithstanding anything in this opinion letter to the contrary, we express no opinion
whatsoever regarding the following:

          1. the compliance or noncompliance of any real estate, personal property or business
operations of the Company with federal, state or local laws, statutes, ordinances, rules or
regulations;

an indemnitee from the gross negligence or willful misconduct of such indemnitee, its predecessor

          6. as to the validity, enforceability or effectiveness of the following contractual
provisions to the extent included in the Transaction Documents: (a) provisions which authorize
self-help, (b) provisions which purport to establish evidentiary standards, (c) provisions which
purport to render ineffective any waiver or modification not in writing, (d) provisions related to
the waiver of rights or remedies (including, without limitation, waivers of notices and hearing,

and stays of execution, waivers of statutes of limitations and waivers of duties which may be
imposed upon a Purchaser) or the delay or omission of enforcement thereof, (e) provisions
purporting to waive any objection to the laying of venue or any claim that an action or proceeding
has been brought in an inconvenient forum, (f) agreements by the Company to submit to the
