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 purchase the

8

 

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
hereto, 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 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

9

 

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 Common Deemed Outstanding immediately prior to such
issuance or sale, plus (2) the consideration, if any, received by the

10

 

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, the Series C
Warrants or the Series D Warrants;

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

          (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 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 Eight Hundred Thousand (800,000) shares (or such greater or
lesser number of shares as may be approved by a majority of the Board (including at least
one of the Investor Directors)) 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;

          (ix) shares of Common Stock issued or issuable in connection with bona-fide sponsored

Shares, voting as a single class on a Common Equivalent Basis, then outstanding, if required
pursuant to Section 3(c) of the Amended Series B Designation);

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

          (xi) Permitted Issuances; or

          (xii) Options (covering up to an aggregate of Three Hundred Thirty Thousand (330,000)
shares of Common Stock) issued in substitution for outstanding Options;

provided that the aggregate number of shares of Common issued or issuable pursuant to clauses
(viii) and (ix) above shall not exceed Three Hundred Fifty Thousand (350,000) shares (or such
greater or lesser number of shares as may be approved by a majority of the Board (including at
least one of the Investor Directors)) 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.

12

 

          (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 issuance 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 subsection (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 subsection (d), the expiration or 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

13

 

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.

          (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

14

 

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 Organic Change, 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.

     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

15

 

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.

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
securities for the purpose of determining the holders thereof who are entitled to receive any
dividend or distribution, (other than cash dividends payable upon shares of Preferred Stock of the
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
reclassification or recapitalization of the capital stock of the Company or any consolidation or
merger involving the Company and any other Person or any transfer or other disposition of all or
substantially all the assets of the Company to another Person, (c) any voluntary or involuntary
dissolution, liquidation or winding-up of the Company, (d) any amendment of the Certificate of
Incorporation of the Company or (e) any registration or public offering of Common Stock, the
Company shall mail to each Holder of a Warrant in accordance with the provisions of Section
14.2 a notice specifying (i) in the case of a dividend or distribution, the date or expected
date on which 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

16

 

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.

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

17

 

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 AN
AMENDED AND RESTATED WARRANT AGREEMENT, DATED AS OF AUGUST 27, 2009, A COPY OF WHICH IS ON
FILE WITH THE SECRETARY OF THE COMPANY.”

          (iii) “THE TRANSFER, SALE, ASSIGNMENT, PLEDGE OR OTHER DISPOSITION OF THE SECURITIES

SPECIFIED IN THAT CERTAIN SECOND AMENDED AND RESTATED SECURITYHOLDERS’ AGREEMENT, DATED AS
OF AUGUST 27, 2009, AS AMENDED AND MODIFIED FROM TIME TO TIME, AMONG XSTREAM SYSTEMS, INC.

THE TRANSFER OF SUCH
SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO SUCH TRANSFER. A
COPY OF SUCH SECOND 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

SUCH TRANSFER. A COPY OF SUCH SECOND 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 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

19

 

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

     12.1 Deliveries. 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:

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 4.1, 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.

and the Warrants and the consummation of the transactions contemplated hereby and thereby do not
and will not, with or without the passage of time or the 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

14. MISCELLANEOUS

     14.1 Nonwaiver.

          No course of dealing or any delay or failure to exercise any right hereunder on the part of

rights, powers or remedies of such Person.

          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
for any loss incurred by reason of a breach by it of the provisions of this Agreement, and hereby
agrees, in an action for specific performance, to waive the defense that a remedy at law would be
adequate.

     14.6 Successors and Assigns.

assigns.

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.

8

 

          (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 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

9

 

     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
hereto, 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 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”).

10

 

     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 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, the Series B
Warrants or the Series D Warrants;

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

          (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 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 Eight Hundred Thousand (800,000) shares (or such greater or
lesser number of shares as may be approved by a majority of the Board (including at least
one of the Investor Directors)) 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;

11

 

          (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;

          (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 Amended Series C Designation);

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

          (xi) Permitted Issuances; or

          (xii) Options (covering up to an aggregate of Three Hundred Thirty Thousand (330,000)
shares of Common Stock) issued in substitution for outstanding Options;

provided that the aggregate number of shares of Common issued or issuable pursuant to clauses
(viii) and (ix) above shall not exceed Three Hundred Fifty Thousand (350,000) shares (or such
greater or lesser number of shares as may be approved by a majority of the Board (including at
least one of the Investor Directors)) 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

12

 

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.

          (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 issuance 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 subsection (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

13

 

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 subsection (d), the expiration or 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

14

 

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.

          (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 Organic Change, 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.

     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.

15

 

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

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.

17

 

     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 AN
AMENDED AND RESTATED
WARRANT AGREEMENT, DATED AS OF AUGUST 27, 2009, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.”

          (iii) “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

OF AUGUST 27, 2009, 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 TRANSFER. A COPY OF SUCH SECOND 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 ANY APPLICABLE STATE

18

 

SECURITIES LAWS, OR IS MADE IN A TRANSACTION EXEMPT FROM SUCH REGISTRATION REQUIREMENTS.”

          (ii) “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 SECOND AMENDED AND RESTATED SECURITYHOLDERS’ AGREEMENT, DATED AS

THE TRANSFER OF SUCH SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO
SUCH TRANSFER. A COPY OF SUCH SECOND 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 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,

19

 

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.

and what actions the Company has taken or has proposed to take with respect thereto;

          (e) promptly upon receipt thereof, any additional reports, management letters or other

statements to changes resulting from normal year-end adjustments (none of which would, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect).

13. REPRESENTATIONS AND WARRANTIES

     13.1 Holders.

          Each Holder, by its acceptance of a Warrant, represents that (i) it is an “accredited
investor,” as that term is defined in Rule 501(a) of Regulation D promulgated under the Securities
Act, (ii) it is acquiring such Warrant for its own account, not as a nominee or agent, with the
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 4.1, 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.

21

 

     13.2 Company.

          The Company has full legal right, power and authority to enter into and perform this Agreement
and to issue the Warrants and to perform all its obligations relating thereto. The execution and
delivery of this Agreement, the issuance of the Warrants by the Company and the consummation of the
transactions contemplated hereby and thereby have all been duly authorized by the Board of the
Company and, where required, the stockholders of the Company. No consent, waiver or authorization
of, or filing with any other Person is required in connection with any of the foregoing or with the
validity or enforceability against the Company of this Agreement or the Warrants. This Agreement
has been duly executed and delivered by the Company and constitutes the legal, valid and binding
obligation of the Company, enforceable in accordance with its terms, except as may be limited by
bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally and
subject to general principles of equity. The execution, delivery and performance of this Agreement
and the Warrants and the consummation of the transactions contemplated hereby and thereby do not
and will not, with or without the
passage of time or the 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 authorized and validly issued free and clear of all liens,
encumbrances, equities and claims, are fully paid and non-assessable, and constitutes the legal,
valid and binding obligations of the Company, enforceable in accordance with their terms, except as
may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’
rights generally and subject to general principles of equity.

14. MISCELLANEOUS

     14.1 Nonwaiver.

          No course of dealing or any delay or failure to exercise any right hereunder on the part of
the Company or the Holders shall operate as a waiver of such right or otherwise prejudice the
rights, powers or remedies of such Person.

     14.2 Notice Generally.

          Any notice, demand, request, consent, approval, declaration, delivery or communication
hereunder to be made pursuant to the provisions of this Agreement shall be sufficiently given or
made if in writing and either delivered in person with receipt acknowledged or sent by registered
or certified mail, return receipt requested, postage prepaid, addressed as follows:

          (i) if to any Holder of Warrants, at its last known address appearing on the books of
the Company maintained for such purpose;

          (ii) if to the Company, at its Designated Office;

or at such other address as may be substituted by notice given as herein provided. The giving of
any notice required hereunder may be waived in writing by the party entitled to receive such
notice. Every notice, demand, request, consent, approval, declaration, delivery or other

22

 

communication hereunder shall be deemed to have been duly given or served on the date on which
personally delivered, with receipt acknowledged, or three (3) Business Days after the same shall
have been deposited in the United States mail, or one (1) Business Day after the same shall have
been delivered to Federal Express or another overnight courier service.

     14.3 Indemnification.

          If the Company fails to make, when due, any payments provided for in this Agreement, the
Company shall pay to the applicable Holder (a) interest at the Agreed Rate on
any amounts due and owing to such Holder and (b) such further amounts as shall be sufficient
to cover any costs and expenses including reasonable attorneys’ fees and expenses incurred by such
Holder in collecting any amounts due hereunder. The Company shall indemnify, save and hold
harmless the Holders from and against any and all liability, loss, cost, damage, reasonable
attorneys’ and accountants’ fees and expenses, court costs and all other out-of-pocket expenses
incurred in connection with or arising from a Company Default. This indemnification provision
shall be in addition to the rights of such Holder or Holders to bring an action against the Company
for breach of contract based on such Company Default.

     14.4 Limitation of Liability; No Stockholder Rights.

          No provision hereof, in the absence of affirmative action by the Holder to purchase shares of
Common Stock, and no enumeration herein of the rights or privileges of the Holders, shall give rise
to any liability or right of any such Holder to pay the Exercise Price for any Warrant Stock or any
liability or rights as a stockholder of the Company, in each case other than pursuant to an
exercise of a Warrant and in each case whether such liability is asserted by the Company or by
creditors of the Company.

     14.5 Remedies.

          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
for any loss incurred by reason of a breach by it of the provisions of this Agreement, and hereby
agrees, in an action for specific performance, to waive the defense that a remedy at law would be
adequate.

     14.6 Successors and Assigns.

          Subject to the provisions of Sections 4.1 and 9, this Agreement and the rights
evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company
and the permitted successors and assigns of the Holders. The provisions of this Agreement are
intended to be for the benefit of all Holders from time to time of Warrants, and shall be
enforceable by any such Holder and, as provided in Section 4.1, such Holder’s permitted
assigns.

provided, however, that no such modification or amendment that would treat any Holder in a
discriminatory manner may be made without the prior written consent of such Holder.

     14.8 Severability.

          Wherever possible, each provision of this Agreement shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this Agreement shall be
prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Agreement.

     14.9 Governing Law; Jurisdiction.

          In all respects, including all matters of construction, validity and performance, this
Agreement and the Warrants and the obligations arising hereunder and thereunder shall be governed

contracts made and performed in such state, except with respect to the validity of this Agreement
and the Warrants, the issuance of Warrant Stock upon exercise of the Warrants and the rights and
