 VOID AFTER 5:00 P.M. NEW YORK CITY LOCAL TIME, MAY 10, 2011. 
 UNIT PURCHASE OPTION 
 FOR THE PURCHASE OF 
              UNITS 
 OF 
 EPAK INTERNATIONAL LIMITED 
 1. Purchase Option.

 THIS CERTIFIES THAT, in consideration of $             duly paid by
or on behalf of                  (“Holder”), as registered owner of this Purchase Option, to ePAK International Limited
(“Company”), Holder is entitled, at any time or from time to time, at or before 5:00 p.m., New York City local time, May 10, 2011 (“Expiration Date”), but not thereafter, to subscribe for,
purchase and receive, in whole or in part, up to                  units (“Units”) of the Company, each Unit consisting of one share of
common stock of the Company, par value $0.0001 per share (“Common Stock”), and two warrants (“Warrant(s)”) expiring on the Expiration Date. Each Warrant is the same as the warrants issued by the
Company in exchange for the warrants of Ascend Acquisition Corp. in the redomestication merger described in the proxy statement/ prospectus dated             , 2008
(“Public Warrants”). 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 $7.50 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 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 Legend. Each certificate for the securities
purchased under this Purchase Option shall bear a legend as follows unless such securities have been registered under the Securities Act of 1933, as amended (“Act”): 
 “The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (“Act”) or applicable
state law. The securities may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable state law.”








 2.3 Cashless Exercise. 
 2.3.1 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 (“Cashless Exercise Right”) as follows: upon exercise of the Cashless Exercise 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 

  

 2 








 
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 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 2.3 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. 
 2.3.1
Mechanics of Cashless Exercise. 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. 

2.4 No Obligation to Net Cash Settle. Notwithstanding anything to the contrary contained in this Purchase Option, if the Company is unable to
deliver any securities pursuant to the exercise of this Purchase Option, the Purchase Option and underlying securities may expire unexercised or unredeemed if there is no effective registration statement covering the securities underlying the
Purchase Option and the Company will have no obligation to pay such registered holder any cash or otherwise “net cash settle” the Purchase Option or the Warrants underlying the Purchase Option. 
 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 except in 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 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 

  

 3 








 
opinion of Graubard Miller 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 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 register (the “Demand Registration”) under the Act on one
occasion, all or any portion 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 or a post-effective amendment to the Registration Statement covering the Registrable
Securities 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 number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. 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 

  

 4 








 
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 such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten
offering. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable
Securities in the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their securities through 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, 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 (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 May 11, 2006 (the 

  

 5 








 
“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 the Company does not have to continue its obligations under Section 5.1 with respect to such proposed offering. 
 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 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 cause any registration statement or post-effective amendment filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of
nine consecutive months from the effective date of such registration statement or post-effective amendment. 
 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 

  

 6 








 
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 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, 

  

 7 








 
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 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 Intentionally Omitted. 
 5.4 General Terms. 
 5.4.1
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 5 of the Underwriting Agreement between the Company, EBC 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. 
 5.4.2 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. 
 5.4.3 Documents Delivered to Holders. The Company shall furnish EBC, as representative of 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’ 

  

 9 








 
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 EBC, as representative of 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 EBC, as
representative of 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 EBC, as representative of the Holders, shall reasonably request. The Company shall not be required to disclose any confidential information or other
records to EBC, as representative of 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. 
 5.4.4 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. 
 5.4.5 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 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). 
  

 10 








 5.4.6 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 6.4 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
$6.00 per whole Unit (each Warrant underlying the Units is exercisable for $5.00 per share), upon effectiveness of the dividend, this Purchase Option will be adjusted to allow for the purchase of one Unit at $6.00 per Unit, each Unit entitling the
holder to receive two shares of Common Stock and four Warrants (each Warrant exercisable for $2.50 per share). 
 6.1.2 Aggregation of
Shares. If after the date hereof, and subject to the provisions of Section 6.4, 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 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. 
 6.2 [Intentionally Omitted] 
 6.3
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. 
 6.4 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 

  

 12 








 
the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the 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 

  

 13 








 
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 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:

 9. Miscellaneous. 
 9.1 Amendments. The Company and EBC 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 and EBC may deem necessary or desirable and that the Company and EBC deem 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. 
  

 14 








 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 New York or of the United States of America for the Southern District of New York, 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 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 Exchange
Agreement. As a condition of the Holder’s receipt and acceptance of this Purchase Option, Holder agrees that, at any time prior to the complete exercise of this Purchase Option by Holder, if the Company and EBC enter into an agreement
(“Exchange Agreement”) pursuant to which they agree that all outstanding Purchase Options will be exchanged for securities or cash or a combination of both, then Holder shall agree to such exchange and become a party to the
Exchange Agreement. 
 9.9 Intentionally Omitted.
