UNIT PURCHASE OPTION 

FOR
THE PURCHASE OF 

750,000
UNITS 

OF

BOOMERANG
HOLDINGS, INC. 

1.     Purchase Option. 

        THIS
CERTIFIES THAT, in consideration of $100.00 duly paid by or on behalf of                          ("Holder"), as
registered owner of this Purchase Option, to Boomerang Holdings, Inc. ("Company"), Holder is entitled, at any time or from time to time upon the
later of the consummation of a Business Combination or                        , 2007 ("Commencement
Date"), and at or before 5:00 p.m., New York City
local time,                        , 2010 ("Expiration Date"), but not
thereafter, to subscribe for, purchase and receive, in whole or in part, up to seven-
hundred fifty thousand (750,000) units ("Units") of the Company, each Unit consisting of one share of common stock of the Company, par value $0.01 per
share ("Common Stock"), and one warrant ("Warrant") expiring four (4) years from the effective
date ("Effective Date") of the registration statement ("Registration Statement") pursuant to which Units
are offered for sale to the public ("Offering"). Each Warrant is the same as the warrants included in the Units being registered for sale to the public
by way of the Registration Statement ("Public Warrants"), except that the exercise price of the Warrant is $7.20 per share. If the Expiration Date is a
day on which banking institutions are authorized by law to close, then this Purchase Option may be exercised on the next succeeding day which is not such a day in accordance with the terms herein.
During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate the Purchase Option. This Purchase Option is initially exercisable at $9.60 per Unit so
purchased; provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted by this Purchase Option, including the exercise price per Unit and
the number of Units (and shares of Common Stock and Warrants) to be received upon such exercise, shall be adjusted as therein specified. The term "Exercise
Price" shall mean the initial exercise price or the adjusted exercise price, depending on the context. 

2.     Exercise. 

        2.1.    Exercise Form.    In order to exercise this Purchase Option, the exercise form
attached hereto must be duly executed and completed and delivered to the Company, together with this Purchase 

1

 

Option
and payment of the Exercise Price for the Units being purchased payable in cash or by certified check or official bank check. If the subscription rights represented hereby shall not be
exercised at or before 5:00 p.m., New York City local time, on the Expiration Date this Purchase Option shall become and be void without further force or effect, and all rights represented
hereby shall cease and expire. 

        2.2.    Cashless Exercise.    

	2.2.1
	Determination of Amount.    In lieu of the payment of the Exercise Price multiplied by the number of Units for which this
Purchase Option is exercisable (and in lieu of being entitled to receive Common Stock and Warrants) in the manner required by Section 2.1, the Holder shall have the right (but not the
obligation) to convert any exercisable but unexercised portion of this Purchase Option into Units ("Conversion Right") as follows: upon exercise of the
Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Exercise Price in cash) that number of Units (or that number of shares of Common Stock and
Warrants comprising that number of Units) equal to the quotient obtained by dividing (x) the Value (as defined below) of the portion of the Purchase Option being converted by (y) the
Current Market Value (as defined below). The "Value" of the portion of the Purchase Option being converted shall equal the remainder derived from
subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this Purchase Option being converted from (b) the Current Market Value of a
Unit multiplied by the number of Units underlying the portion of the Purchase Option being converted. As used herein, the term "Current Market Value"
per Unit at any date means: (A) in the event that neither the Units nor Public Warrants are still trading, the remainder derived from subtracting (x) the exercise price of the Warrants
multiplied by the number of shares of Common Stock issuable upon exercise of the Warrants underlying one Unit from (y) (i) the Current Market Price of the Common Stock multiplied by
(ii) the number of shares of Common Stock underlying one Unit, which shall include the shares of Common Stock underlying the Warrants included in such Unit; (B) in the event that the
Units, Common Stock and Public Warrants are still trading, (i) if the Units are listed on a national securities exchange or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or NASD
OTC Bulletin Board (or successor exchange), the last sale price of the Units in the principal trading market for the Units as reported by the exchange, Nasdaq or the NASD, as the case may be, on the
last trading day preceding the date in question; or (ii) if the Units are not listed on a national securities exchange or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or the
NASD OTC Bulletin Board (or successor exchange), but is traded in the residual over-the-counter market, the closing bid price for Units on the last trading day preceding the
date in question for which such quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations; and (C) in the event that the Units are not still trading but the Common
Stock and Public Warrants underlying the Units are still trading, the Current Market Price of the Common Stock plus the product of (x) the Current Market Price of the Public Warrants and
(y) the number of shares of Common Stock underlying the Warrants included in one Unit. The "Current Market Price" shall mean (i) if the
Common Stock (or Public Warrants, as the case may be) is listed on a national securities exchange or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or NASD OTC Bulletin Board (or
successor exchange), the last sale price of the Common Stock (or Public Warrants) in the principal trading market for the Common Stock as reported by the exchange, Nasdaq or the NASD, as the case may
be, on the last trading day preceding the date in question; (ii) if the Common Stock (or Public Warrants, as the case may be) is not listed on a national securities exchange or quoted on the
Nasdaq National Market, Nasdaq SmallCap Market or the NASD OTC Bulletin Board (or successor exchange), but is traded in the residual over-the-counter market, the closing bid
price for the Common Stock (or Public Warrants) on the last trading day preceding the date in question for which such quotations are reported by 

2

 

the
Pink Sheets, LLC or similar publisher of such quotations; and (iii) if the fair market value of the Common Stock cannot be determined pursuant to clause (i) or (ii) above,
such price as the Board of Directors of the Company shall determine, in good faith. In the event the Public Warrants have expired and are no longer exercisable, no
"Value" shall be attributed to the Warrants underlying this Purchase Option. Additionally, in the event that this Purchase Option is exercised pursuant
to this Section 2.2 and the Public Warrants are still trading, the "Value" shall be reduced by the difference between the Warrant Exercise Price
and the exercise price of the Public Warrants multiplied by the number of
Warrants underlying the Units included in the portion of this Purchase Option being converted. 

	2.2.2
	Mechanics of Cashless Exercise.    The cashless exercise right described in this Section 2.2 (the
"Cashless Exercise Right") may be exercised by the Holder on any business day on or after the Commencement Date and not later than the Expiration Date
by delivering the Purchase Option with the duly executed exercise form attached hereto with the cashless exercise section completed to the Company, exercising the Cashless Exercise Right and
specifying the total number of Units the Holder will purchase pursuant to such Cashless Exercise Right. 

3.     Transfer. 

        3.1.    General Restrictions.    The registered Holder of this Purchase Option, by its
acceptance hereof, agrees that it will not sell, transfer, assign, pledge or hypothecate this Purchase Option for a period of one year following the Effective Date to anyone other than
(i) Deutsche Bank or an underwriter or a selected dealer in connection with the Offering, or (ii) a bona fide officer or partner of Deutsche Bank or of any such underwriter or selected
dealer. On and after the first anniversary of the Effective Date, transfers to others may be made subject to compliance with or exemptions from applicable securities laws. In order to make any
permitted assignment, the Holder must deliver to the Company the assignment form attached hereto duly executed and completed, together with the Purchase Option and payment of all transfer taxes, if
any, payable in connection therewith. The Company shall within five business days transfer this Purchase Option on the books of the Company and shall execute and deliver a new Purchase Option or
Purchase Options of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of Units purchasable hereunder or such portion of such number as shall be
contemplated by any such assignment. 

        3.2.    Restrictions Imposed by the Act.    The securities evidenced by this Purchase Option
shall not be transferred unless and until (i) the Company has received the opinion of counsel for the Holder that the securities may be transferred pursuant to an exemption from registration
under the Securities Act of 1933, as amended ("Act") and applicable state securities laws, the availability of which is established to the reasonable
satisfaction of the Company (the Company hereby agreeing that the opinion of Sonnenschein Nath & Rosenthal LLP shall be deemed satisfactory evidence of the availability of an exemption), or
(ii) a registration statement or a post-effective amendment to the Registration Statement relating to such securities has been filed by the Company and declared effective by the
Securities and Exchange Commission (the "Commission") and compliance with applicable state securities law has been established. 

4.     New Purchase Options to be Issued. 

        4.1.    Partial Exercise or Transfer.    Subject to the restrictions in Section 3
hereof, this Purchase Option may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Option for cancellation,
together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax, the Company shall cause to be delivered to the Holder without charge a
new Purchase Option of like tenor to this Purchase Option in the name of the Holder evidencing the right of the Holder to 

3

 

purchase
the number of Units purchasable hereunder as to which this Purchase Option has not been exercised or assigned. 

        4.2.    Lost Certificate.    Upon receipt by the Company of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Purchase Option and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver a new Purchase Option of
like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute contractual obligation on the part of
the Company. 

5.     Registration Rights. 

        5.1.    Demand Registration.    

	5.1.1
	Grant of Right.    The Company, upon written demand ("Initial Demand
Notice") of the Holder(s) of at least 51% of the Purchase Options and/or the underlying Units and/or the underlying securities ("Majority
Holders"), agrees to use its best efforts to register (the "Demand Registration") under the Act on one occasion, all of the
Purchase Options requested by the Majority Holders in the Initial Demand Notice and all of the securities underlying such Purchase Options, including the Units, Common Stock, the Warrants and the
Common Stock underlying the Warrants (collectively, the "Registrable Securities"). On such occasion, the Company will file a registration
statement for use in an offering of the Registrable Securities from time-to-time or a post-effective amendment to the Registration Statement covering all of the
Registrable Securities that will permit an offering of the Registrable Securities from time-to-time within sixty days after receipt of the Initial Demand Notice and use its
best efforts to have such registration statement or post-effective amendment declared effective as soon as possible thereafter. The demand for registration may be made at any time during a
period of five years beginning on the Effective Date. The Initial Demand Notice shall specify the intended method(s) of distribution of the Registrable Securities. The Company will notify all holders
of the Purchase Options and/or Registrable Securities of the demand within ten days from the date of the receipt of any such Initial Demand Notice. Each holder of Registrable Securities who wishes to
include all or a portion of such holder's Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in such registration, a
"Demanding Holder") shall so notify the Company within fifteen (15) days after the receipt by the holder of the notice from the Company. Upon any
such request, the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand Registration, subject to Section 5.1.4.

	5.1.2
	Effective Registration.    A registration will not count as a Demand Registration until the registration statement filed
with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under this Agreement with respect thereto; provided,
however, that if, after such registration statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or
injunction of the Commission or any other governmental agency or court, the registration statement with respect to such Demand Registration will be deemed not to have been declared effective, unless
and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter
elect to continue the offering.

	5.1.3
	Underwritten Offering.    If the Majority Holders so elect and such holders so advise the Company as part of the Initial
Demand Notice, the offering of all or any portion of the Registrable Securities pursuant to such Demand Registration shall be in the form of one underwritten offering. All Demanding Holders proposing
to distribute their securities through 

4

 

such
underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Majority Holders. 

	5.1.4
	Reduction of Offering.    If the managing underwriter or underwriters for a Demand Registration that is to be an
underwritten offering advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell pursuant
to the underwritten offering, taken together with all other shares of Common Stock or other securities which the Company desires to sell and the shares of Common Stock, if any, as to which
registration has been requested pursuant to written contractual piggy-back registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar
amount or maximum number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such
offering (such maximum dollar amount or maximum number of shares, as applicable, the "Maximum Number of Shares"), then the Company shall include in such
registration: (i) first, the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders that want to participate in such underwritten offering (pro rata
in accordance with the number of shares that each such Person has requested be included in such registration, regardless of the number of shares held by each such Person (such proportion is referred
to herein as "Pro Rata")) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of
Shares has not been reached under the foregoing clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number
of Shares; (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (i) and (ii), the shares of Common Stock or other securities
registrable pursuant to the terms of the Registration Rights Agreement between the Company and the initial investors in the Company, dated as of    , 2006 (the
"Registration Rights Agreement" and such registrable securities, the "Investor Securities") as to which
"piggy-back" registration has been requested by the holders thereof, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (iv) fourth, to the extent that
the Maximum Number of Shares have not been reached under the foregoing clauses (i), (ii), and (iii), the shares of Common Stock or other securities for the account of other persons that the Company is
obligated to register pursuant to written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Shares.

	5.1.5
	Withdrawal.    If a majority-in-interest of the Demanding Holders disapprove of the terms of any
underwriting or are not entitled to include all of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from
such offering by giving written notice to the Company and the underwriter or underwriters of their request to withdraw prior to the effectiveness of the registration statement filed with the
Commission with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration,
then such registration shall not count as a Demand Registration provided for in Section 5.1.

	5.1.6
	Terms The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the expenses of any
legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders shall pay any and all underwriting commissions. The Company agrees to
use its reasonable best efforts to qualify or register the Registrable Securities in such states as are reasonably requested by the Majority Holder(s); provided, however, that in no event shall the
Company be required to register the Registrable Securities in a state in which such registration would cause (i) the Company to be obligated to qualify to do business in such state, or would
subject the 

5

 

Company
to taxation as a foreign corporation doing business in such jurisdiction or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the
Company. The Company shall use its best efforts to cause any registration statement or post-effective amendment filed pursuant to the demand rights granted under Section 5.1.1 to
remain effective until the expiration of the Warrants in accordance with the terms and conditions of that certain Warrant Agreement, dated as
of                        , 2006, between the Company and
Continental Stock Transfer & Trust Company. The Company shall not be obligated to deliver securities to the holder until such time, if any, that a registration statement is declared effective.
If the Company uses its best efforts to comply with such provisions then it shall have no liability due to a delay in the registration or the effectiveness of such registration statement and in no
event will the Company be required to net cash settle the exercise of the Purchase Option. 

        5.2.    Piggy-Back Registration.    

	5.2.1
	Piggy-Back Rights. If at any time during the seven year period commencing on the Effective Date the Company proposes to
file a registration statement under the Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity
securities, by the Company for its own account or for stockholders of the Company for their account (or by the Company and by stockholders of the Company including, without limitation, pursuant to
Section 5.1), other than a registration statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of
securities solely to the Company's existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment
plan, then the Company shall (x) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days
before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed
managing underwriter or underwriters, if any, of the offering, and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of
shares of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a "Piggy-Back
Registration"). The Company shall cause such Registrable Securities to be included in such registration and shall use its best efforts to cause the managing underwriter or
underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar
securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable
Securities proposing to distribute their securities through a Piggy-Back Registration that involves an underwriter or underwriters shall enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such Piggy-Back Registration.

	5.2.2
	Reduction of Offering.    If the managing underwriter or underwriters for a Piggy-Back Registration that is to
be an underwritten offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock which the Company desires to sell, taken
together with shares of Common Stock, if any, as to which registration has been demanded pursuant to written contractual arrangements with persons other than the holders of Registrable Securities
hereunder, the Registrable Securities as to which registration has been requested under this Section 5.2, and the shares of Common Stock, if any, as to which registration has been requested
pursuant to the written contractual 

6

 

piggy-back
registration rights of other stockholders of the Company, exceeds the Maximum Number of Shares, then the Company shall include in any such registration: 

        (a)   If
the registration is undertaken for the Company's account: (A) first, the shares of Common Stock or other securities that the Company desires to sell that can
be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of
Common Stock or other securities, if any, comprised of Registrable Securities and Investor Securities, as to which registration has been requested pursuant to the applicable written contractual
piggy-back registration rights of such
security holders, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of shares has not been reached under the
foregoing clauses (A) and (B), the shares of Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual
piggy-back registration rights with such persons and that can be sold without exceeding the Maximum Number of Shares; 

        (b)   If
the registration is a "demand" registration undertaken at the demand of holders of Investor Securities,
(A) first, the shares of Common Stock or other securities for the account of the demanding persons, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; (B) second,
to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Common Stock or other securities that the Company desires to sell that can be
sold without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the shares
of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth,
to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other securities for the account of other
persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Shares; and 

        (c)   If
the registration is a "demand" registration undertaken at the demand of persons other than either the holders of
Registrable Securities or of Investor Securities, (A) first, the shares of Common Stock or other securities for the account of the demanding persons that can be sold without exceeding the
Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Common Stock or other securities
that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the
foregoing clauses (A) and (B), collectively the shares of Common Stock or other securities comprised of Registrable Securities and Investor Securities, Pro Rata, as to which registration has
been requested pursuant to the terms hereof and of the Registration Rights Agreement, as applicable, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the
extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other securities for the account of other persons that
the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Shares. 

	5.2.3
	Withdrawal.    Any holder of Registrable Securities may elect to withdraw such holder's request for inclusion of
Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the registration statement. The
Company (whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a 

7

 

registration
statement at any time prior to the effectiveness of the registration statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of
Registrable Securities in connection with such Piggy-Back Registration as provided in Section 5.2.4. 

	5.2.4
	Terms.    The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the
expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities but the Holders shall pay any and all underwriting commissions related
to the Registrable Securities. In the event of such a proposed registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than fifteen days written
notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for each applicable registration statement filed (during the period in
which the Purchase Option is exercisable) by the Company until such time as all of the Registrable Securities have been registered and sold. The Holders of the Registrable Securities shall exercise
the "piggy-back" rights provided for herein by giving written notice, within ten days of the receipt of the Company's notice of its intention to file a registration statement. The
Company shall cause any registration statement filed pursuant to the above "piggyback" rights to remain effective for at least nine months from the date that the Holders of the Registrable Securities
are first given the opportunity to sell all of such securities. 

        5.3.    General Terms.    

	5.3.1
	Indemnification.    The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any
registration statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934,
as amended ("Exchange Act"), against all loss, claim, damage, expense or liability (including all reasonable attorneys' fees and other expenses reasonably incurred in investigating, preparing or
defending against litigation, commenced or threatened, or any claim whatsoever whether arising out of any action between the underwriter and the Company or between the underwriter and any third party
or otherwise) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect as the
provisions pursuant to which the Company has agreed to indemnify the underwriters contained in Section [8] of the Underwriting Agreement between the Company, Deutsche Bank and
the other underwriters named therein dated the Effective Date. The Holder(s) of the Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall
severally, and not jointly, indemnify the Company, its officers and directors and each person, if any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, against all loss, claim, damage, expense or liability (including all reasonable attorneys' fees and other expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders,
or their successors or assigns, in writing, for specific inclusion in such registration statement to the same extent and with the same effect as the provisions contained in Section 5 of the
Underwriting Agreement pursuant to which the underwriters have agreed to indemnify the Company.

	5.3.2
	Exercise of Purchase Options.    Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to
exercise their Purchase Options or Warrants underlying such Purchase Options prior to or after the initial filing of any registration statement or the effectiveness thereof. 

8

 

	5.3.3
	Documents Delivered to Holders.    The Company shall furnish to the Holders participating in any of the foregoing
offerings, a signed counterpart, addressed to the participating Holders, of (i) an opinion of counsel to the Company, dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, an opinion dated the date of the closing under any underwriting agreement related thereto), and (ii) a "cold comfort" letter dated the
effective date of such registration statement (and, if such registration includes an underwritten public offering, a letter dated the date of the closing under the underwriting agreement) signed by
the independent public accountants who have issued a report on the Company's financial statements included in such registration statement, in each case covering substantially the same matters with
respect to such registration statement (and the prospectus included therein) and, in the case of such accountants' letter, with respect to events subsequent to the date of such financial statements,
as are customarily covered in opinions of issuer's counsel and in accountants' letters delivered to underwriters in underwritten public offerings of securities. The Company shall also deliver promptly
to the Holders participating in the offering, the correspondence and memoranda described below and copies of all correspondence between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit the Holders, to do such investigation, upon reasonable advance notice, with
respect to information contained in or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of the National Association of
Securities Dealers, Inc. ("NASD"). Such investigation shall include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often as the Holders shall reasonably request. The Company shall
not be required to disclose any confidential information or other records to the Holders, or to any other person, until and unless such persons shall have entered into reasonable confidentiality
agreements (in form and substance reasonably satisfactory to the Company), with the Company with respect thereto. 

        5.4.    Underwriting Agreement.    The Company shall enter into an underwriting agreement with
the managing underwriter(s), if any, selected by any Holders whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably
acceptable to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and such managing underwriters, and shall contain such representations,
warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting
agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations, warranties and covenants of the Company to or for the
benefit of such underwriters shall also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with the Company
or the underwriters except as they may relate to such Holders and their intended methods of distribution. Such Holders, however, shall agree to such covenants and indemnification and contribution
obligations for selling stockholders as are customarily contained in agreements of that type used by the managing underwriter. Further, such Holders shall execute appropriate custody agreements and
otherwise cooperate fully in the preparation of the registration statement and other documents relating to any offering in which they include securities pursuant to this Section 5. Each Holder
shall also furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably required to
effect the registration of the Registrable Securities. 

	5.4.1
	Rule 144 Sale.    Notwithstanding anything contained in this Section 5 to the contrary, the Company shall
have no obligation pursuant to Sections 5.1 or 5.2 for the registration of 

9

 

Registrable
Securities held by any Holder (i) where such Holder would then be entitled to sell under Rule 144 within any three-month period (or such other period prescribed under
Rule 144 as may be provided by amendment thereof) all of the Registrable Securities then held by such Holder, and (ii) where the number of Registrable Securities held by such Holder is
within the volume limitations under paragraph (e) of Rule 144 (calculated as if such Holder were an affiliate within the meaning of Rule 144). 

	5.4.2
	Supplemental Prospectus.    Each Holder agrees, that upon receipt of any notice from the Company of the happening of any
event as a result of which the prospectus included in the registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, such Holder will immediately discontinue disposition of Registrable Securities
pursuant to the registration statement covering such Registrable Securities until such Holder's receipt of the copies of a supplemental or amended prospectus, and, if so desired by the Company, such
Holder shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of such destruction) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. 

6.     Adjustments. 

        6.1.    Adjustments to Exercise Price and Number of Securities.    The Exercise Price and the
number of Units underlying the Purchase Option shall be subject to adjustment from time to time as hereinafter set forth: 

	6.1.1
	Stock Dividends—Split-Ups.    If after the date hereof, and subject to the provisions of
Section 6.3 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split-up of shares of Common Stock or
other similar event, then, on the effective date thereof, the number of shares of Common Stock underlying each of the Units purchasable hereunder shall be increased in proportion to such increase in
outstanding shares. In such case, the number of shares of Common Stock, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be
adjusted in accordance with the terms of the Warrants. For example, if the Company declares a two-for-one stock dividend and at the time of such dividend this Purchase Option
is for the purchase of one Unit at $9.60 per whole Unit (each Warrant underlying the Units is exercisable for $7.20 per share), upon effectiveness of the dividend, this Purchase Option will be
adjusted to allow for the purchase of one Unit at $9.60 per Unit, each Unit entitling the holder to receive two shares of Common Stock and four Warrants (each Warrant exercisable for $3.30 per share).

	6.1.2
	Aggregation of Shares.    If after the date hereof, and subject to the provisions of Section 6.3, the number of
outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, on the effective date thereof, the number of
shares of Common Stock underlying each of the Units purchasable hereunder shall be decreased in proportion to such decrease in outstanding shares. In such case, the number of shares of Common Stock,
and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

	6.1.3
	Replacement of Securities upon Reorganization, etc.    In case of any reclassification or reorganization of the outstanding
shares of Common Stock other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such shares of Common 

10

 

Stock,
or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that
does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the property of the
Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have the right thereafter (until the expiration of
the right of exercise of this Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of
shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or
transfer, by a Holder of the number of shares of Common Stock of the Company obtainable upon exercise of this Purchase Option and the underlying Warrants immediately prior to such event; and if any
reclassification also results in a change in shares of Common Stock covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this
Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. 

	6.1.4
	Changes in Form of Purchase Option.    This form of Purchase Option need not be changed because of any change pursuant to
this Section, and Purchase Options issued after such change may state the same Exercise Price and the same number of Units as are stated in the Purchase Options initially issued pursuant to this
Agreement. The acceptance by any Holder of the issuance of new Purchase Options reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the
Commencement Date or the computation thereof.

	6.1.5
	Adjustments of Warrants.    To the extent the price of the Warrants is lowered pursuant to Section 3.1 of the
Warrant Agreement, dated                        , 2006, between the Company and Continental Stock Transfer & Trust
Company (the "Warrant Agreement") the
price of the Warrants underlying the Purchase Option shall be reduced on identical terms, subject to any limitations and conditions that may be imposed by NASD Corporate Financing Rule 2710 and
any such reduction must remain in effect for at least twenty (20) business days. To the extent the duration of the Warrants is extended pursuant to Section 3.2 of the Warrant Agreement,
the duration of the Warrants underlying the Purchase Option shall be extended on identical terms, subject to any limitations that may be imposed by NASD Corporate Financing Rule 2710. 

        6.2.    Substitute Purchase Option.    In case of any consolidation of the Company with, or
merger of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger which does not result in any reclassification or change of the outstanding Common
Stock), the corporation formed by such consolidation or merger shall execute and deliver to the Holder a supplemental Purchase Option providing that the holder of each Purchase Option then outstanding
or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Option) to receive, upon exercise of such Purchase Option, the kind and amount of shares of stock and
other securities and property receivable upon such consolidation or merger, by a holder of the number of shares of Common Stock of the Company for which such Purchase Option might have been exercised
immediately prior to such consolidation, merger, sale or transfer. Such supplemental Purchase Option shall provide for adjustments which shall be identical to the adjustments provided in
Section 6. The above provision of this Section shall similarly apply to successive consolidations or mergers. 

        6.3.    Elimination of Fractional Interests.    The Company shall not be required to issue
certificates representing fractions of shares of Common Stock or Warrants upon the exercise of the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any fractional
interests, it being the 

11

 

intent
of the parties that all fractional interests shall be eliminated by rounding any fraction up to the nearest whole number of Warrants, shares of Common Stock or other securities, properties or
rights. 

        7.    Reservation and Listing.    The Company shall at all times reserve and keep available
out of its authorized shares of Common Stock, solely for the purpose of issuance upon exercise of the Purchase Options or the Warrants underlying the Purchase Option, such number of shares of Common
Stock or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Options and payment of the Exercise
Price therefor, all shares of Common Stock and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive
rights of any stockholder. The Company further covenants and agrees that upon exercise of the Warrants underlying the Purchase Options and payment of the respective Warrant exercise price therefor,
all shares of Common Stock and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any
stockholder. As long as the Purchase Options shall be outstanding, the Company shall use its best efforts to cause all (i) Units and shares of Common Stock issuable upon exercise of the
Purchase Options, (iii) Warrants issuable upon exercise of the Purchase Options and (iv) shares of Common Stock issuable upon exercise of the Warrants included in the Units issuable upon
exercise of the Purchase Option to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on the Nasdaq National Market, SmallCap Market, OTC Bulletin Board
or any successor trading market) on which the Units, the Common Stock or the Public Warrants issued to the public in connection herewith may then be listed and/or quoted. 

8.     Certain Notice Requirements. 

        8.1.    Holder's Right to Receive Notice.    Nothing herein shall be construed as conferring
upon the Holders the right to vote or consent as a stockholder for the election of directors or any other matter, or as having any rights whatsoever as a stockholder of the Company. If, however, at
any time prior to the expiration of the Purchase Options and their exercise, any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give
written notice of such event at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such
dividend, distribution, conversion or exchange of securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such
record date or the date of the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder a copy of each notice given to the other
stockholders of the Company at the same time and in the same manner that such notice is given to the stockholders. 

        8.2.    Events Requiring Notice.    The Company shall be required to give the notice described
in this Section 8 upon one or more of the following events: (i) if the Company shall take a record of the holders of its shares of Common Stock for the purpose of entitling them to
receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained earnings, as indicated by the accounting treatment of such
dividend or distribution on the books of the Company, or (ii) the Company shall offer to all the holders of its Common Stock any additional shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor, or (iii) a dissolution, liquidation or winding up of the
Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business shall be proposed. 

        8.3.    Notice of Change in Exercise Price.    The Company shall, promptly after an event
requiring a change in the Exercise Price pursuant to Section 6 hereof, send notice to the Holders of such event and change ("Price Notice"). The
Price Notice shall describe the event causing the change and the 

12

 

method
of calculating same and shall be certified as being true and accurate by the Company's President and Chief Financial Officer. 

        8.4.    Transmittal of Notices.    All notices, requests, consents and other communications
under this Purchase Option shall be in writing and shall be deemed to have been duly made when hand delivered, or mailed by express mail or private courier service: (i) if to the registered
Holder of the Purchase Option, to the address of such Holder as shown on the books of the Company, or (ii) if to the Company, to the following address or to such other address as the Company
may designate by notice to the Holders: 

Boomerang

Chesterfield, Missouri 63017

Attn: Chief Executive Officer 

9.     Miscellaneous. 

        9.1.    Amendments.    The Company may from time to time supplement or amend this Purchase
Option without the approval of any of the Holders in order to cure any ambiguity, to correct or supplement any provision contained herein that may be defective or inconsistent with any other
provisions herein, or to make any other provisions in regard to matters or questions arising hereunder that the Company may deem necessary or desirable and that the Company, in the exercise of
reasonable judgment, determines that it shall not adversely affect the interest of the Holders. All other modifications or amendments shall require the written consent of and be signed by the party
against whom enforcement of the modification or amendment is sought. 

        9.2.    Headings.    The headings contained herein are for the sole purpose of convenience of
reference, and shall not in any way limit or affect the meaning or interpretation of any of the terms or provisions of this Purchase Option. 

        9.3.    Entire Agreement.    This Purchase Option (together with the other agreements and
documents being delivered pursuant to or in connection with this Purchase Option) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all
prior agreements and understandings of the parties, oral and written, with respect to the subject matter hereof. 

        9.4.    Binding Effect.    This Purchase Option shall inure solely to the benefit of and shall
be binding upon, the Holder and the Company and their permitted assignees, respective successors, legal representative and assigns, and no other person shall have or be construed to have any legal or
equitable right, remedy or claim under or in respect of or by virtue of this Purchase Option or any provisions herein contained. 

        9.5.    Governing Law; Submission to Jurisdiction.    This Purchase Option shall be governed
by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflict of laws. The Company hereby agrees that any action, proceeding or claim against it
arising out of, or relating in any way to this Purchase Option shall be brought and enforced in the courts of the State of Illinois or of the United States of America for the Northern District of
Illinois, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an
inconvenient forum. Any process or summons to be served upon the Company may be served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid,
addressed to it at the address set forth in Section 8 hereof. Such mailing shall be deemed personal service and shall be legal and binding upon the Company in any action, proceeding or claim.
The Company and the Holder agree that the prevailing party(ies) in any such action shall be entitled to recover from the other party(ies) all of its 

13

 

reasonable
attorneys' fees and expenses relating to such action or proceeding and/or incurred in connection with the preparation therefor. 

        9.6.    Waiver, Etc.    The failure of the Company or the Holder to at any time enforce any of
the provisions of this Purchase Option shall not be deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Purchase Option or any provision hereof or
the right of the Company or any Holder to thereafter enforce each and every provision of this Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of any
of the provisions of this Purchase Option shall be effective unless set forth in a written instrument executed by the party or parties against whom or which enforcement of such waiver is sought; and
no waiver of any such breach, non-compliance or non- fulfillment shall be construed or deemed to be a waiver of any other or subsequent breach or non-compliance. 

        9.7.    Execution in Counterparts.    This Purchase Option may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same
agreement, and shall become
effective when one or more counterparts has been signed by each of the parties hereto and delivered to each of the other parties hereto. 

        9.8.    Underlying Warrants.    At any time after exercise by the Holder of this Purchase
Option, the Holder may exchange his Warrants (with an initial exercise price of $7.20) for Public Warrants (with an initial exercise price of $6.00) upon payment to the Company of the difference
between the exercise price of his Warrant and the exercise price of the Public Warrants. Any such Public Warrants and the Common Stock underlying such Public Warrants shall constitute Registrable
Securities. 

        IN
WITNESS WHEREOF, the Company has caused this Purchase Option to be signed by its duly authorized officer as of the              day of
                         , 2006.

Exhibit 10.10  

 
 

STOCK ESCROW AGREEMENT    
    

        STOCK ESCROW AGREEMENT, dated as of                        , 2006
("Agreement"), by and among BOOMERANG
HOLDINGS, INC., a Delaware corporation ("Company"), each of the stockholders of the Company set forth on Exhibit A, annexed hereto
(collectively "Initial Stockholders") and CONTINENTAL STOCK TRANSFER & TRUST COMPANY, a New York corporation ("Escrow
Agent"). 

        WHEREAS,
the Company has entered into an Underwriting Agreement, dated                        , 2006 ("Underwriting Agreement"), with Deutsche
Bank Securities Inc. ("Deutsche Bank") acting as representative of the several underwriters (collectively, the
"Underwriters"), pursuant to which, among other matters, the Underwriters have agreed to purchase 15,000,000 units
("Units") of the Company. Each Unit consists of one share of the Company's common stock, par value $0.01 per share ("Common
Stock"), and one warrant to purchase one share of Common Stock, all as more fully described in the Company's final Prospectus,
dated                        , 2006 comprising part of
the Company's Registration Statement on Form S-1 (File No. 333-135081) under the Securities Act of 1933, as amended ("Registration
Statement"), declared effective on                        , 2006 ("Effective
Date"). 

        WHEREAS,
the Initial Stockholders have agreed as a condition of the sale of the Units to deposit their shares of Common Stock of the Company, as set forth opposite their respective names
on Exhibit A attached hereto (collectively "Escrow Shares"), in escrow as hereinafter provided. 

        WHEREAS,
the Company and the Initial Stockholders desire that the Escrow Agent accept the Escrow Shares, in escrow, to be held and disbursed as hereinafter provided. 

        IT
IS AGREED: 

        1.     Appointment of Escrow Agent.    The Company and the Initial Stockholders hereby appoint the Escrow Agent to act
in accordance with and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms. 

        2.     Deposit of Escrow Shares.    On or before the Effective Date, each of the Initial Stockholders shall deliver to
the Escrow Agent certificates (with a medallion guaranteed stock power) representing his respective Escrow Shares, to be held and disbursed subject to the terms and conditions of this Agreement. Each
Initial Stockholder acknowledges that the certificate representing his Escrow Shares is legended to reflect the deposit of such Escrow Shares under this Agreement. 

        3.     Disbursement of the Escrow Shares.    The Escrow Agent shall hold the Escrow Shares until the third anniversary
of the Effective Date ("Escrow Period") (provided, however, that with respect to 363,000 of Mr. Gregg Eisenberg's Escrow Shares, the Escrow
Period shall be ninety days following the consummation of a business combination (as such term is defined in the Registration Statement; hereinafter, a "Business
Combination")), on which date it shall, upon written instructions from each Initial Stockholder, disburse each of the Initial Stockholder's Escrow Shares to such Initial
Stockholder; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company is being liquidated at any time during the Escrow Period,
then the Escrow Agent shall promptly destroy the certificates representing the Escrow Shares; provided further, however, that if, after the Company consummates a Business Combination, it (or the
surviving entity) subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results in all of the stockholders of such entity having the right to exchange their
shares of Common Stock for cash, securities or other property, then the Escrow Agent will, upon receipt of a certificate, executed by the Chief Executive Officer or Chief Financial Officer of the
Company, in form reasonably acceptable to the Escrow Agent, that such transaction is then being consummated, release the Escrow Shares to the 

1

 

Initial
Stockholders upon consummation of the transaction so that they can similarly participate. The Escrow Agent shall have no further duties hereunder after the disbursement or destruction of the
Escrow Shares in accordance with this Section 3. 

4.     Rights of Initial Stockholders in Escrow Shares. 

        4.1.  Voting Rights as a Stockholder.    Subject to the terms of the Insider Letter described in Section 4.4
hereof and except as herein provided, the Initial Stockholders shall retain all of their rights as stockholders of the Company during the Escrow Period, including, without limitation, the right to
vote such shares. 

        4.2.  Dividends and Other Distributions in Respect of the Escrow Shares.    During the Escrow Period, all dividends
payable in cash with respect to the Escrow Shares shall be paid to the Initial Stockholders, but all dividends payable in stock or other non-cash property
("Non-Cash Dividends") shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term
"Escrow Shares" shall be deemed to include the Non-Cash Dividends distributed thereon, if any. 

        4.3.  Restrictions on Transfer.    During the Escrow Period, no sale, transfer or other disposition may be made of
any or all of the Escrow Shares except (i) by gift to a member of Initial Stockholder's immediate family or to a trust, the beneficiary of which is an Initial Stockholder or a member of an
Initial Stockholder's immediate family, (ii) by virtue of the laws of descent and distribution upon death of any Initial Stockholder, or (iii) pursuant to a qualified domestic relations
order; provided, however, that such permissive transfers may be implemented only upon the respective transferee's written agreement to be bound by the terms and conditions of this Agreement and of the
Insider Letter signed by the Initial Stockholder transferring the Escrow Shares. During the Escrow Period, the Initial Stockholders shall not pledge or grant a security interest in the Escrow Shares
or grant a security interest in their rights under this Agreement. 

        4.4.  Insider Letters.    Each of the Initial Stockholders has executed a letter agreement with the Company, dated
as indicated on Exhibit A hereto, and which is filed as an exhibit to the Registration Statement ("Insider Letter"), respecting the rights and
obligations of such Initial Stockholder in certain events, including but not limited to the liquidation of the Company. 

5.     Concerning the Escrow Agent. 

        5.1.  Good Faith Reliance.    The Escrow Agent shall not be liable for any action taken or omitted by it in good
faith and in the exercise of its own best judgment, and may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including
counsel chosen by the Escrow Agent), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the
truth and acceptability of any information therein contained) which is believed by the Escrow Agent to be genuine and to be signed or presented by the proper person or persons. The Escrow Agent shall
not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or
parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto. 

        5.2.  Indemnification.    The Escrow Agent shall be indemnified and held harmless by the Company from and against
any expenses, including counsel fees and disbursements, or loss suffered by the Escrow Agent in connection with any action, suit or other proceeding involving any claim which in any way, directly or
indirectly, arises out of or relates to this Agreement, the services of the Escrow Agent hereunder, or the Escrow Shares held by it hereunder, other than expenses or losses arising from the gross
negligence or willful misconduct of the Escrow Agent. Promptly after the receipt by the Escrow 

2

 

Agent
of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in writing. In the event of the receipt of such
notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine ownership or disposition of the Escrow Shares or it may
deposit the Escrow Shares with the clerk of any appropriate court or it may retain the Escrow Shares pending receipt of a final, non-appealable order of a court having jurisdiction over
all of the parties hereto directing to whom and under what circumstances the Escrow Shares are to be disbursed and delivered. The provisions of this Section 5.2 shall survive in the event the
Escrow Agent resigns or is discharged pursuant to Sections 5.5 or 5.6 below. 

        5.3.  Compensation.    The Escrow Agent shall be entitled to reasonable compensation from the Company for all
