BACKSTOP AND SUBSCRIPTION AGREEMENT

 

This Backstop and Subscription
Agreement (this “Agreement”), made as of May 11, 2017 by and among Pacific Special Acquisition Corp.,
a British Virgin Islands business company with limited liability (the “Company”), and Zhengqi International
Holding Limited, a company incorporated in the British Virgin Islands (the “Subscriber”), is intended
to set forth certain representations, covenants and agreements among the Company and the Subscriber, with respect to the acquisition
by Subscriber of the Company’s ordinary shares of no par value (the “Ordinary Shares”), for aggregate
consideration of up to Twenty-Four Million U.S. Dollars ($24,000,000), through such acquisitions as are described in Sections 1(a)(iii)
and (iv) hereof, which representations, covenants and agreements are made in connection with the Company’s acquisition of
Borqs International Holding Corp, an exempted company incorporated under the laws of the Cayman Islands with limited liability
(“Borqs”), in accordance with that certain Merger Agreement, dated as of December 27, 2016 (as amended,
including by Amendment No.1 thereto on or about the date hereof, the “Merger Agreement”), by and among
the Company, PAAC Merger Subsidiary Limited, Zhengqi International Holding Limited in its capacity thereunder as the Purchaser
Representative, Zhengdong Zou in its capacity thereunder as the Seller Representative and, for certain limited purposes thereunder,
the Subscriber. Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the
Merger Agreement.

 

1.             Transfer
and Voting of Shares.

 

(a)        Subscriber
covenants and agrees that until the earlier of (i) the closing under the Merger Agreement (the “Merger Closing”)
or (ii) the date on which the Merger Agreement is terminated in accordance with its terms (the “Termination Date”),
it shall not, and shall ensure that each of its Affiliates do not, Transfer any Ordinary Shares (other than Ordinary Shares held
by the Subscriber as of the date hereof, the proceeds of which were not deposited by the Company into the Trust Account in connection
with the IPO). For purposes hereof, “Affiliate” shall mean affiliate as such term is defined in Rule
12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and “Transfer”
shall mean any direct or indirect transfer, redemption, disposition or monetization in any manner whatsoever, including through
redemption election or any derivative transactions.

 

(b)        Subscriber
covenants and agrees that it shall, and shall cause each of its Affiliates to, (i) vote all of the Ordinary Shares that it owns
as of the record date (the “Record Date”) for the Shareholder Meeting in favor of the Merger and the
other Shareholder Approval Matters at the Shareholder Meeting and (ii) not exercise its redemption or conversion rights with respect
to any Ordinary Shares that it owns as of the Record Date in connection with the Shareholder Meeting.

 

2.             Backstop.

 

(a)        Commencing
on the date hereof and through 5:00 p.m. Eastern Time on the last date on which it may purchase Ordinary Shares such that the
settlement of such purchase shall occur on or before the Record Date (the “Market Deadline”), Subscriber
shall (provided it is lawful to do so) have the right to purchase up to Twenty-Four Million U.S. Dollars ($24,000,000) of Ordinary
Shares in the open market or in other privately negotiated transactions with third parties. On the date immediately following
the Market Deadline and promptly at other times requested by the Company from time to time, Subscriber shall notify the Company
in writing of the number of Ordinary Shares so purchased (the “Open Market Shares”) and the aggregate
purchase price paid therefor by the Subscriber.

 

     

     

    

 

(b)        Between
the Market Deadline and the close of business on the third Trading Day prior to the Shareholder Meeting (the “Private
Purchase Deadline”), if the Company reasonably believes in good faith that it will have less than Twenty-Four Million
U.S. Dollars ($24,000,000) in Closing Proceeds (as defined below) after giving effect to any Open Market Shares previously purchased
by the Subscriber pursuant to Section 2(a) hereof, it will promptly notify the Subscriber of the anticipated shortfall of Closing
Proceeds below $24,000,000 (the “Expected Shortfall”), and Subscriber shall (provided it is lawful to
do so) use its commercially reasonable efforts to purchase an amount of Ordinary Shares up to the Expected Shortfall in privately
negotiated transactions with third parties, including forward contracts (such shares, the “Private Purchase Shares”
and, together with the Open Market Shares, the “Market Shares”), provided that: (i) such transactions
settle no later than, and are conditioned upon, the Merger Closing and (ii) Subscriber shall not be required to purchase any Ordinary
Shares at a price above $10.40 per share. Notwithstanding the foregoing, Subscriber shall be permitted (provided it is lawful
to do so) prior to the Private Purchase Deadline to buy additional Ordinary Shares in such private transactions in excess of the
Expected Shortfall, up to a total of $24,000,000 in total Market Shares. On the date immediately following the Private Purchase
Deadline, and at such other times as may be requested by the Company from time to time, Subscriber shall (x) notify the Company
in writing of the number of Private Purchase Shares so purchased and the aggregate purchase price paid therefor by Subscriber
and (y) provide the Company, for all Private Purchase Shares acquired, all documentary evidence reasonably requested by the Company
and its advisors (including its legal counsel) and its transfer agent and proxy solicitor to confirm that: (i) the Subscriber
purchased, or has contracted to purchase, such shares, and (ii) the seller of such shares has provided to the Subscriber a representation
that (A) the seller voted such shares in favor of the Merger and the other Shareholder Approval Matters and (B) the seller of
such shares did not exercise its redemption or conversion rights for such shares in connection with the Shareholder Meeting or
the Merger Closing. Notwithstanding the foregoing, and for the avoidance of doubt, if the Merger Agreement is terminated in accordance
with its terms prior to the Merger Closing, then the Subscriber’s obligations to purchase Ordinary Shares under this Section
2(b) will immediately terminate and be extinguished. For purposes of this Agreement, (i) “Closing Proceeds”
means the sum of (A) the funds left in the Trust Account as of the Merger Closing, after giving effect to any redemptions or conversions
by Public Stockholders, but before giving effect to the payment of any Transaction Expenses, plus (B) the amount of funds from
any private placements of the Company’s capital stock (or binding commitments therefor, other than the Subscriber’s
obligations in the Backstop Offering) occurring or to occur at or prior to the Merger Closing, and (ii) “Trading Day”
shall mean a day during which trading in the Ordinary Shares generally occurs on the Nasdaq or, if the Ordinary Shares are not
listed on the Nasdaq, on the principal other national or regional securities exchange on which the Ordinary Shares are then listed
or, if the Ordinary Shares are not listed on a national or regional securities exchange, on the principal other market on which
the Ordinary Shares are then listed or admitted for trading.

 

(c)         Immediately after the deadline for the Public Stockholders to elect to redeem or convert their Ordinary Shares from
funds in the Trust Account in connection with the Merger Closing, the Company shall notify the Subscriber of the updated Expected
Shortfall anticipated at such time and after giving effect to any Market Shares previously purchased (or committed to be purchased)
by the Subscriber pursuant to Sections 2(a) and 2(b) hereof (the “Final Shortfall”). The Subscriber hereby
irrevocably subscribes for and agrees, subject to the substantially concurrent Merger Closing and the other terms and conditions
set forth herein, to purchase from the Company that number of Ordinary Shares equivalent to the Final Shortfall at a purchase price
of $10.40 per share (such shares, the “Backstop Shares”), and the Company agrees to sell such Backstop
Shares to the Subscriber at such price per share (such offering, the “Backstop Offering”); provided,
that, if requested by the Subscriber, the Company shall (provided it is lawful to do so) issue and sell to the Subscriber an additional
number of Backstop Shares in the Backstop Offering, up to a total of Twenty-Four Million U.S. Dollars ($24,000,000) when aggregated
with all amounts for Market Shares and Backstop Shares (the “Backstop Cap”). For the avoidance of doubt,
if the Merger Agreement is terminated in accordance with its terms prior to the Merger Closing, then the Subscriber’s obligations
to purchase Backstop Shares under this Section 2(c) will immediately terminate and be extinguished. Any such purchase under this
Section 2(c) shall be consummated substantially concurrent with the Merger Closing. For the avoidance of doubt, in the event that
no Market Shares are acquired by the Subscriber pursuant to Sections 2(a) and 2(b) hereof, the Subscriber’s obligations under
this Section 2(c) shall nevertheless continue to apply.

Shares will be issued in the name of the Subscriber and deposited in the Guarantee Escrow Account, to be held by the Escrow Agent
in accordance with the terms of the Merger Agreement and the Escrow Agreement for the Guarantee Escrow Account, and the Subscriber
shall be entitled to receive the Backstop Guarantee Escrow Share Amount from the Guarantee Escrow Account subject to, and in accordance
with, the terms and conditions of the Merger Agreement. The Company will, and will use its reasonable efforts to cause the Seller
Representative to, promptly provide any required notices to the Escrow Agent to cause the timely release of the Backstop Guarantee
Escrow Share Amount in accordance with the Merger Agreement to the extent that the Subscriber is entitled to such amounts in accordance
with the Merger Agreement.

attached hereto as Exhibit A (the “Investor Questionnaire”) and, in respect of the Backstop Offering
pursuant to Section 2(c) hereof, upon notice from the Company setting forth the reasonably anticipated date of the Merger Closing,
the Subscriber shall, no fewer than two (2) Business Days prior to such anticipated date (the “Funding Date”),
cause a wire transfer to be made for payment for the Backstop Shares in immediately available funds in the aggregate amount equal
to $10.40 multiplied by the number of Backstop Shares to be purchased by the Subscriber (the “Subscription Amount”)
to the account(s) designated in writing by the Company to the Subscriber prior to the Merger Closing. In the event that the Subscriber
enters into privately negotiated transactions with third parties in accordance with Section 2(b) hereof subsequent to the Funding
Date but prior to the Merger Closing, unless otherwise requested in writing by the Subscriber (but subject to the Backstop Cap),
the Subscription Amount shall be reduced by the dollar amount of such purchases and such excess funds (not to exceed the Subscription
Amount) shall be returned to the Subscriber. The payments provided for in this Section 2(a) shall be deposited in escrow with
Continental Stock Transfer & Trust Company (or other nationally recognized escrow agent with whom in all cases, whether with
Continental Stock Transfer & Trust Company or otherwise, the Company shall have an escrow agreement in place for purposes
hereof, which such agreement shall be on reasonable and customary terms) pending the Company’s acceptance of the subscription.

 

(b)        The
subscription of the Subscriber for the Backstop Shares shall be deemed to be accepted only (and shall not otherwise be accepted
by the Company except) when (i) the Company has confirmed in writing to the Subscriber that the Company’s representations
and warranties contained herein are, or shall be, true and correct as of the date of the Company’s acceptance of such subscription
and (ii) the Merger Closing occurs substantially concurrent with the Company’s acceptance of such subscription. If such
acceptance does not occur on or prior to the earlier of (x) the Merger Closing or (y) the Termination Date, the Subscriber’s
subscription shall automatically be deemed rejected (the “Subscription Rejection”). The payment of the
Subscription Amount will be returned promptly, without interest, to the Subscriber if the subscription is rejected in whole or
in part or if the Backstop Offering is withdrawn or canceled.

 

(c)        The
representations and warranties of the Company and the Subscriber set forth herein shall be true and correct as of the date that
the Company accepts the subscriptions set forth herein.

5.             Expenses.
Each party hereto shall pay all of its own expenses in connection with this Agreement and the transactions contemplated hereby.

 

6.             Registration
Rights.

 

(a)        At the Merger Closing, the Company and the Subscriber shall enter into a Registration Rights Agreement (the “Registration
Rights Agreement”), pursuant to which the Company will agree to (i) register the resale of the Backstop Shares, any
Guarantee Escrow Shares received by the Subscriber from the applicable Escrow Account and not forfeited in accordance with the
Merger Agreement (the “Subscriber Earnout Shares”), and any Market Shares requested by the Subscriber
under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations promulgated
thereunder, and applicable state securities laws, (ii) use reasonable best efforts to cause such registration with respect to such
Backstop Shares and such Market Shares to be declared effective no later than one-hundred and twenty (120) days following the Merger
Closing (provided, that the Company shall have no obligation to register the resale of any Subscriber Earnout Shares until they
are actually received by the Subscriber from the Escrow Account) and (iii) provide the Subscriber with customary demand and piggyback
registration rights. The Registration Rights Agreement shall include such additional terms and conditions as are customary and
reasonably satisfactory to the Company and the Subscriber.

 

(b)        None
of the Backstop Shares or Subscriber Earnout Shares may be Transferred except pursuant to an effective registration statement
or in a transaction that is exempt from the registration requirements of the Securities Act and applicable state securities laws.

 

(c)        Without
limitation to the generality of the foregoing, the Subscriber shall not execute any short sales or engage in other hedging transactions
of any kind with respect to any Ordinary Shares during the period from the date of the Merger Closing through the date that is
forty-five (45) consecutive days thereafter. For the avoidance of doubt, the prohibition set forth in this Section 6(c) shall
not be applicable on or after the Termination Date.

 

7.             Representations,
Warranties, Understandings, Risk Acknowledgments, and Covenants of The Subscriber. The Subscriber hereby represents, warrants
and covenants to the Company as follows:

 

(a)        The
Subscriber is purchasing the Backstop Shares and acquiring the Subscriber Earnout Shares, if any, for its own account, not as
a nominee or agent, for investment purposes and not with a view towards distribution or resale within the meaning of the Securities
Act (absent the registration of the Backstop Shares and Subscriber Earnout Shares for resale under the Securities Act or a valid
exemption from registration). The Subscriber will not Transfer such shares at any time in violation of the Securities Act or applicable
state securities laws. The Subscriber acknowledges that the Backstop Shares and Subscriber Earnout Shares cannot be sold unless

from the registration and prospectus delivery requirements of the Securities Act, (C) will be issued in reliance upon exemptions
from the registration and prospectus delivery requirements of applicable state securities laws which relate to private offerings
and (D) may be required to be held indefinitely because of the fact that the Backstop Shares and Subscriber Earnout Shares have

of bearing the economic risk of its investment hereunder indefinitely unless a subsequent disposition thereof is registered under
the Securities Act and applicable state securities laws or is exempt therefrom. The Subscriber further understands that such exemptions
depend upon, among other things, the bona fide nature of the investment intent of the Subscriber expressed herein. Pursuant to
the foregoing, the Subscriber acknowledges that until such time as the resale of the Backstop Shares and Subscriber Earnout Shares
has been registered under the Securities Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant
to an exemption from registration, the certificates representing any Backstop Shares and Subscriber Earnout Shares acquired by
the Subscriber shall bear a restrictive legend substantially as follows (and a stop-transfer order may be placed against transfer

(c)        The Subscriber has knowledge, skill and experience in financial, business and investment matters relating to an investment
of this type and is capable of evaluating the merits and risks of such investment and protecting the Subscriber’s interest
in connection with the acquisition of the Backstop Shares, Subscriber Earnout Shares and the Market Shares (collectively, the “Shares”).
The Subscriber understands that the acquisition of the Shares is a speculative investment and involves substantial risks and that

the risks identified in the Disclosure Documents (as defined below) and (ii) carefully considered the risks related to the Merger,
the Company, and Borqs and has taken full cognizance of and understands all of the risks related to the Company, Borqs, the Merger,
the Shares and the transactions contemplated hereby, including the purchase of the Shares. Acknowledging the very significant tax
impact analysis and other analyses that is warranted in determining the consequences to it of purchasing and owning the Shares,
to the extent deemed necessary by the Subscriber, the Subscriber has had the opportunity to retain, at its own expense, and relied
upon, appropriate professional advice regarding the investment, tax and legal merits and consequences of the foregoing, including
purchasing and owning the Shares. The Subscriber has the ability to bear the economic risks of the Subscriber’s investment
in the Company, including a complete loss of the investment, and the Subscriber has no need for liquidity in such investment.

 

(d)        The
Subscriber has been furnished by the Company all information (or provided access to all information it reasonably requested) regarding

No. 1 thereto; and (iv) the proposed draft amendments to the preliminary Proxy Statement based on the SECs comments, Amendment
No. 1 to the Merger Agreement and this Agreement and other recent events. The Subscriber understands the significant extent to
which certain of the disclosures contained in items (i) and (ii) above shall no longer apply following the Merger Closing.

 

(f)         The
Subscriber acknowledges that neither the Company nor any of its Affiliates has made or makes any representation or warranty to

(g)        In
making its investment decision to purchase the Shares, the Subscriber is relying solely on investigations made by the Subscriber
and the Subscriber’s representatives. The offer to sell the Backstop Shares and issue the Subscriber Earnout Shares was
communicated to the Subscriber in such a manner that the Subscriber was able to ask questions of and receive answers from the
management of the Company concerning the terms and conditions of the proposed transaction and that at no time was the Subscriber
presented with or solicited by or through any advertisement, article, leaflet, public promotional meeting, notice or other communication

or any other form of general or public advertising or solicitation.

Subscriber acknowledges that it has been advised that:

 

(i)            The
Backstop Shares and Subscriber Earnout Shares offered or issued or issuable hereby have not been approved or disapproved by the
SEC or any applicable state securities commission nor has the SEC or any applicable state securities commission passed upon the
accuracy or adequacy of any representations by the Company. Any representation to the contrary is a criminal offense.

 

(ii)           In
making an investment decision, the Subscriber must rely on its own examination of the Company, the Merger, Borqs and the Backstop
Offering, including the merits and risks involved. The Shares have not been recommended by any applicable federal or state securities
commission or regulatory authority. Furthermore, the foregoing authorities have not confirmed the accuracy or determined the adequacy
of any representation by the Company. Any representation to the contrary is a criminal offense.

 

(iii)          The
Backstop Shares and the Subscriber Earnout Shares will be “restricted securities” within the meaning of Rule 144 under
the Securities Act, are subject to restrictions on transferability and resale and may not be transferred or resold except as permitted
under the Securities Act and applicable state securities laws, pursuant to the applicable registration requirements or exemption
therefrom. The Subscriber is aware that the provisions of Rule 144 are not currently available and, in the future, may not become
available for resale of any of the Backstop Shares and Subscriber Earnout Shares and that the Company is an issuer subject to
Rule 144(i) under the Securities Act. The Subscriber is aware that it may be required to bear the financial risks of this investment
for an indefinite period of time.

Subscriber agrees to furnish the Company with such other information as the Company may reasonably request in order to verify
the accuracy of the information contained herein and agrees to notify the Company immediately of any material change in the information
provided herein that occurs prior to the acceptance of this Agreement by the Company.

 

(j)          The
Subscriber further represents and warrants that the Subscriber is a “qualified institutional buyer” within the meaning

the Securities Act, and Subscriber has executed the Investor Questionnaire and shall provide to the Company an updated Investor
Questionnaire promptly following any change in circumstances at any time on or prior to the Merger Closing.

 

(k)         As
of the date of this Agreement, the Subscriber and its Affiliates do not have, and during the thirty (30) day period prior to the
date of this Agreement the Subscriber and its Affiliates did not enter into, any “put equivalent position” as such
term is defined in Rule 16a-1 of under the Exchange Act or short sale positions with respect to the securities of the Company.
In addition, the Subscriber shall comply with all applicable provisions of Regulation M promulgated under the Securities Act.

 

(l)         If the Subscriber is a natural person, the Subscriber has reached the age of majority in the state in which the Subscriber
resides, has adequate means of providing for the Subscriber’s current financial needs and contingencies, is able to bear
the substantial economic risks of an investment in the Shares for an indefinite period of time, has no need for liquidity in such
investment and, at the present time, can afford a complete loss of such investment.

 

    	 	7	 

     

    

 

(m)       If
the Subscriber is a partnership, corporation, trust, estate or other entity (an “Entity”): (i) the Entity
has the full legal right and power and all authority and approval required (a) to execute and deliver, or authorize execution
and delivery of, this Agreement and all other instruments executed and delivered by or on behalf of the Entity in connection with
the acquisition of the Shares, (b) to delegate authority pursuant to power of attorney and (c) to acquire and hold such Shares;
(ii) the signature of the party signing on behalf of the Entity is binding upon the Entity; and (iii) the Entity has not been
formed for the specific purpose of acquiring the Shares, unless each beneficial owner of such entity is a “qualified institutional
buyer” within the meaning of Rule 144A under the Securities Act or is qualified as an accredited investor within the meaning
of Rule 501(a) of Regulation D promulgated under the Securities Act and has submitted information substantiating such individual
qualification.

 

(n)        If
the Subscriber is a retirement plan or is investing on behalf of a retirement plan, the Subscriber acknowledges that investment
in the Shares poses additional risks including the inability to use losses generated by an investment in the Shares to offset
taxable income.

 

(o)        This
Agreement has been duly authorized, executed and delivered by the Subscriber and constitutes a legal, valid and binding obligation
of the Subscriber enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited
by: (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws in effect that limit creditors’
rights generally; (ii) equitable limitations on the availability of specific remedies; (iii) principles of equity (regardless
of whether such enforcement is considered in a proceeding in law or in equity); and (iv) to the extent rights to indemnification
and contribution may be limited by federal securities laws or the public policy underlying such laws.

 

(p)              
The Subscriber understands and confirms that the Company will rely on the representations and covenants of the Subscriber
contained herein in effecting the transactions contemplated by this Agreement and the other Transaction Documents (as defined herein).
All representations and warranties provided to the Company by or on behalf of the Subscriber, taken as a whole, are true and correct
and do not contain any untrue statement of material fact or omit to state any material fact necessary in order to make the statements
made therein, in the light of the circumstances under which they were made, not misleading.

 

(q)        Neither the purchase of the Backstop Shares nor the acquisition of the Subscriber Earnout Shares by the Subscriber
will subject the Company to any of the “Bad Actor” disqualifications described in Rule 506(d) under the Securities
Act.

 

(r)         Unless
otherwise specified in the Investor Questionnaire, the Subscriber is not a U.S. person (as defined in the Securities Act) and
is acquiring the Backstop Shares and Subscriber Earnout Shares in an offshore transaction in accordance with the requirements
of Regulation S under the Securities Act.

and performance of this Agreement and the other Transaction Documents by the Company and the consummation by it of the transactions
contemplated hereby and thereby have been duly and validly authorized by all requisite corporate action, and no other proceedings
on the Company’s part are necessary to authorize the execution, delivery or performance of this Agreement and the other
Transaction Documents. This Agreement and each of the other Transaction Documents have been duly executed and delivered by the
Company, and, assuming that this Agreement and the Registration Rights Agreement constitute a valid and binding obligation of
the Subscriber, this Agreement and each of the other Transaction Documents will constitute upon execution and delivery by the
Company, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except
as such enforceability may be limited by: (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws
in effect that limit creditors’ rights generally; (ii) equitable limitations on the availability of specific remedies; (iii)
principles of equity (regardless of whether such enforcement is considered in a proceeding in Law or in equity); and (iv) to the
extent rights to indemnification and contribution may be limited by federal securities laws or the public policy underlying such
laws.

 

(b)        Subject to obtaining the Required Approvals, the execution, delivery and performance of this Agreement and the other
Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby will
not (i) conflict with or result in a violation of any provision of the Company’s Organizational Documents, (ii) violate or
conflict with, or result in a breach of any provision of, or constitute a default (or an event which with notice or lapse of time
or both could become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of,
any material agreement, to which the Company is a party, or (iii) result in a violation of any Law applicable to the Company or
by which any property or asset of the Company is bound or affected (except for such conflicts, defaults, terminations, amendments,
accelerations, cancellations and violations in clauses (ii) or (iii) of this Section 8(b) as have not had or would not reasonably
be expect to have, individually or in the aggregate, a material adverse effect on the business, properties, condition (financial
or otherwise) or results of operations of the Company and its Subsidiaries, taken as a whole (“Material Adverse Effect”)).
The Company is not in violation of its Organizational Documents in any material respect.

 

(c)         Except
for (i) the applicable requirements of any applicable Antitrust Laws, the federal securities Laws or any applicable state securities
or “blue sky” Laws and (ii) the filing of the Plan of Merger with the Registrar of Companies of the Cayman Islands
(and subject to obtaining the Required Approvals), the Company is not required to submit any notice, report or other filing with
any Governmental Authority in connection with the execution, delivery or performance by it of the Transaction Documents or the
consummation of the transactions contemplated by the Transaction Documents and no consent, approval or authorization of any Governmental
Authority or any other Person is required to be obtained by the Company in connection with its execution, delivery and performance
of this Agreement and each of the other Transaction Documents or the consummation of the transactions contemplated hereby and
thereby, (other than such consents, approvals or authorizations, the failure of which to obtain, have not had and would not reasonably
be expected to have, individually or in the aggregate, a Material Adverse Effect).

(d)        The
Company has timely filed all forms, reports and other documents required to be filed by it with the SEC (all of the foregoing
filed prior to the date hereof and all exhibits included therein and financial statements and schedules thereto and documents
(other than exhibits to such documents) incorporated by reference therein, being hereinafter referred to herein as the “SEC
Documents”) since the date of its IPO (the “IPO Date”), or has timely filed for a valid
extension of such time of filing and has filed any such SEC Document prior to the expiration of any such extension. As of their
respective dates, the SEC Documents complied in all material respects in accordance with the requirements of the Securities Act
and the Exchange Act, as the case may be, and the rules and regulations thereunder, and none of the SEC Documents, at the time
they were filed with the SEC (except to the extent that information contained in any SEC Document has been superseded by a later
timely filed SEC Document), contained any untrue statement of a material fact or omitted to state a material fact required to
be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were
made, not misleading.

 

(e)         Each
of the financial statements (including, in each case, any notes thereto) contained in the SEC Documents was prepared in accordance
with U.S. generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout
the periods indicated (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by
Form 10-Q of the SEC) and each fairly presents, in all material respects, the financial position, results of operations and cash
flows of the Company as at the respective dates thereof and for the respective periods indicated therein.

 

(f)         The
Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the
Exchange Act). Such disclosure controls and procedures: (i) are designed to ensure that material information relating to the Company
and its Subsidiaries is made known to the Company’s chief executive officer and its chief financial officer by others within
those entities, particularly during the periods in which the Company’s reports and filings under the Exchange Act are being
prepared, (ii) have been evaluated for effectiveness as of the end of the most recent quarterly period reported to the SEC, and
(iii) are effective to perform the functions for which they were established. The Company is in compliance in all material respects
with the provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder that are applicable
to it.

 

(g)        As
of the date hereof, there are no, and since the Company’s formation, there have not been any Actions pending or, to the
knowledge of the Company, threatened in writing against the Company, including any such Actions that (i) challenges the validity
or enforceability of the Company’s obligations under this Agreement or the other Transaction Documents or (ii) seeks to
prevent, delay or otherwise would reasonably be expected to adversely affect the consummation by the Company of the transactions
contemplated herein or therein.

 

(h)        Except
as and to the extent set forth on the balance sheet of the Company as of December 31, 2016, including the notes thereto, the Company
has no liability or obligation of a type required to be reflected in a balance sheet prepared in accordance with GAAP or in the
footnotes thereto, except for (i) liabilities and obligations incurred since December 31, 2016 in the ordinary course of business
that are not, individually or in the aggregate, material to the Company and none of which results from or arises out of any material
breach of or material default under any contract, material breach of warranty, tort, material infringement or material violation
of Law; (ii) liabilities and obligations incurred in connection with the transactions contemplated by this Agreement and other
Transaction Documents; and (iii) liabilities and obligations which have not had and would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect.

 

(i)         The
Company will file with the SEC a Current Report on Form 8-K or other periodic report under the Exchange Act disclosing the form
of this Agreement within four (4) Business Days after the date of this Agreement.

(j)                
The Company understands and confirms that the Subscriber will rely on the representations and covenants contained
herein in effecting the transactions contemplated by this Agreement.

 

9.             Understandings.
The Subscriber understands, acknowledges and agrees with the Company as follows:

 

(a)        The
Subscriber hereby acknowledges and agrees that, subject to the terms and conditions of this Agreement, the subscription hereunder
is irrevocable by the Subscriber, that, except as required by applicable Law, the Subscriber is not entitled to cancel, terminate
or revoke this Agreement or any agreements of the Subscriber hereunder, and that this Agreement and such other agreements shall
survive the death or disability of the Subscriber and shall be binding upon and inure to the benefit of the parties and their
respective heirs, executors, administrators, successors, legal representatives and permitted assigns.

 

(b)        No
federal or state agency has made any finding or determination as to the accuracy or adequacy of the Disclosure Documents or as
to the suitability of this offering for investment nor any recommendation or endorsement of the Shares.

 

(c)        The
Backstop Offering is intended to be exempt from registration, which is dependent upon the truth, completeness and accuracy of
the statements made by the Subscriber herein.

 

(d)        There
is only a limited public market for the Ordinary Shares. There can be no assurance that a Subscriber will be able to sell or dispose
of the Shares.

 

(e)        The
representations and warranties of the Subscriber contained in this Agreement and in any other writing delivered in connection
with the transactions contemplated hereby shall be true and correct in all respects on and as of the date hereof and the date
of the consummation of each offering of the Backstop Shares and issuance of the Subscriber Earnout Shares as if made on and as
of such date and such representation and warranties and all agreements of the Subscriber contained herein and in any other writing
delivered in connection with the transactions contemplated hereby.

 

10.          Survival.
All representations, warranties and covenants contained in this Agreement shall survive (i) the acceptance of this Agreement by
the Company and (ii) changes in the transactions, documents and instruments described herein which are not material or which are
to the benefit of the Subscriber, in each case until the earlier of the (A) Merger Closing or (B) Termination Date. The Subscriber
acknowledges the meaning and legal consequences of the representations, warranties and covenants contained herein and that the
Company has relied upon such representations, warranties and covenants in determining the Subscriber’s qualification and
suitability to purchase the Shares.

 

    	 	11	 

     

    

 

11.          Waiver
Against Trust. Reference is made to the IPO Prospectus. The Subscriber represents and warrants that it has read the IPO Prospectus
and understands that Company has established the Trust Account containing the proceeds of the IPO (including interest accrued
from time to time thereon) for the benefit of the Public Stockholders and that, except as otherwise described in the IPO Prospectus,
the Company may disburse monies from the Trust Account only: (a) to the Public Shareholders in the event they elect to redeem
their Ordinary Shares in connection with the consummation of its Business Combination, (b) to the Public Shareholders if the Company
fails to consummate a Business Combination by August 21, 2017 or such earlier date as determined by the Company’s directors
(as extended from April 20, 2017), (c) to pay any taxes and for working capital purposes from the interest accrued in the Trust
Account, and (d) to the Company after or concurrently with the consummation of its Business Combination. For and in consideration
of the Company entering into this Agreement and for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the Subscriber hereby agrees on behalf of itself and its Affiliates that, notwithstanding anything to
the contrary in this Agreement, neither the Subscriber nor its Affiliates does now or shall at any time hereafter have any right,
title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make any claim against
the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result of, in connection
with or relating in any way to, any proposed or actual business relationship between the Company or its Representatives, on the
one hand, and the Subscriber or its Representatives, on the other hand, this Agreement or any other matter, and regardless of
whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are
collectively referred to hereafter as the “Released Claims”). The Subscriber on behalf of itself and
its Affiliates hereby irrevocably waives any Released Claims that the Subscriber or its Affiliates may have against the Trust
Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, contracts
or agreements with the Company or its Representatives and will not seek recourse against the Trust Account (including any distributions
therefrom) for any reason whatsoever (including for an alleged breach of this Agreement or any other agreement with the Company
or its Affiliates). The Subscriber agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically
relied upon by the Company and its Affiliates to induce the Company to enter in this Agreement, and the Subscriber further intends
and understands such waiver to be valid, binding and enforceable under applicable Law. To the extent the Subscriber or any of
its Affiliates commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating
to the Company or its Representatives, which proceeding seeks, in whole or in part, monetary relief against the Company or its
Representatives, the Subscriber hereby acknowledges and agrees its sole remedy shall be against funds held outside of the Trust
Account and that such claim shall not permit any the Subscriber or its Affiliates (or any Person claiming on any of their behalves
or in lieu of them) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained
therein. In the event that the Subscriber or any of its Affiliates commences Action based upon, in connection with, relating to
or arising out of any matter relating to the Company or its Representatives which proceeding seeks, in whole or in part, relief
against the Trust Account (including any distributions therefrom) or the Public Shareholders, whether in the form of money damages
or injunctive relief, the Company and its Representatives shall be entitled to recover from the Subscriber, its Affiliates, and
the Subscriber Shareholders, the associated legal fees and costs in connection with any such Action, in the event the Company
or its Representatives, as applicable, prevails in such Action. Notwithstanding anything to the contrary in this Section 11, the
Released Claims shall not include, and this Section 11 shall not otherwise affect, any rights of the Subscriber or its Affiliates
as a Public Stockholder of the Company to receive distributions from the Trust Account in its capacity as a Public Stockholder.
This Section 11 shall survive termination of this Agreement for any reason.

13.           Notification
of Changes. The Subscriber agrees and covenants to notify the Company and Borqs immediately upon the occurrence of any event
prior to the Merger Closing that would cause any representation, warranty, covenant or other statement contained in this Agreement
to be false or incorrect in any material respect or of any material change in any statement made herein occurring prior to the
Merger Closing. The Company agrees and covenants to notify the Subscriber immediately upon the occurrence of any event prior to
the Merger Closing that would cause any representation, warranty, covenant or other statement contained in this Agreement to be
false or incorrect in any material respect or of any material change in any statement made herein occurring prior to the Merger
Closing.

 

14.           Obligations Irrevocable. Subject to the terms and conditions contained herein, the obligations of the Subscriber
to make its subscription provided for hereunder shall be irrevocable, except with the consent of the Company and Borqs, until the
Subscription Rejection.

 

15.          Amendments;
Waiver. This Agreement may be amended, supplemented or modified only by execution of a written instrument signed by the Company,
the Subscriber and Borqs. This Agreement may not be waived except by an instrument in writing signed by the party against whom
enforcement of waiver is sought (and, with respect to any waiver by the Company, Borqs).

 

16.          Assignment.
This Agreement shall not be assigned without the prior written consent of the Company, the Subscriber and Borqs, and any assignment
without such consent shall be null and void ab initio. Notwithstanding the foregoing, the Company and Borqs will not unreasonably
withhold, delay or condition their consent to transfer and assign all or a proportion of the Subscriber’s obligations under
this Agreement to an investor that is a “qualified institutional buyer” within the meaning of Rule 144A under the
Securities Act or an institutional “accredited investor” within the meaning of Rule 501 of Regulation D under the
Securities Act and who otherwise is reasonably expected to be capable of satisfying the Subscriber’s obligations transferred
to such assignee. Such assignee shall be entitled to receive a proportionate share of the Guarantee Escrow Shares based on the
portion of the Subscriber’s obligations transferred to such assignee, as well as entitled to receive the rights and obligations
of the Subscriber under the Registration Rights Agreement with respect to its Shares. Upon any such approved assignment by the
Subscriber, such assignee shall be deemed to be the “Subscriber” under this Agreement (and the Registration Rights
Agreement) with respect to the rights and obligations under this Agreement (and the Registration Rights Agreement) transferred
to such assignee; provided, that each Subscriber shall be severally, and not jointly, liable for any breach of this Agreement
or the Registration Rights Agreement. Notwithstanding the foregoing, in the event that an assignee does not fulfill its purchase
obligations hereunder, the original Subscriber shall be secondarily responsible for fulfilling such purchase obligations, and
the original Subscriber shall (i) be permitted to enforce this Agreement against such assignee on behalf of the Company, (ii)
receive such defaulting assignee’s rights under this Agreement (including its share of the Guarantee Escrow Shares), and
(iii) be entitled to seek any remedies against the defaulting assignee for such default to which it or the Company may be entitled
under this Agreement, such assignment, at law or in equity.

 

17.          Binding
Effect; Third Party Beneficiaries. Except as otherwise provided herein, this Agreement shall be binding upon and inure to
the benefit of the parties and their heirs, successors and assigns, and the agreements, representations, warranties and acknowledgments
contained herein shall be deemed to be made by and be binding upon such heirs, executors, administrators, successors, legal representatives
and assigns. This Agreement does not confer any rights or remedies upon any person or entity other than the parties hereto and
their heirs, successors and permitted assigns, provided, however, that Borqs is an intended third-party beneficiary
of this Agreement, and the Company and the Subscriber hereby acknowledge and agree that Borqs has the right to cause the Company
to enforce its rights and perform its obligations under this Agreement including the right to cause the Company to make or not
make any election or otherwise exercise or not exercise a right hereunder.

 

    	 	14	 

     

    

 

18.           Governing
Law; Jurisdiction; WAIVER OF JURY TRIAL. This Agreement shall be governed by, construed and enforced in accordance with the
Laws of the State of Delaware without regard to the conflict of laws principles thereof. All Actions arising out of or relating
to this Agreement shall be heard and determined exclusively in any state or federal court located in New York, New York (or in
any court in which appeal from such courts may be taken) (the "Specified Courts"). Each party hereto (and
Borqs to the extent of its third party beneficiary rights) hereby (a) submits to the exclusive jurisdiction of any Specified Court
for the purpose of any Action arising out of or relating to this Agreement and (b) irrevocably waives, and agrees not to assert
by way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of
the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient
forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated hereby may not be enforced
in or by any Specified Court. Each party (and Borqs to the extent of its third party beneficiary rights) agrees that a final judgment
in any Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided
by Law. Each party irrevocably consents to the service of the summons and complaint and any other process in any other Action
relating to the transactions contemplated by this Agreement, on behalf of itself, or its property, by personal delivery of copies
of such process to such party at the applicable address set forth in Section 12. Nothing in this Section 18 shall affect the right
of any party to serve legal process in any other manner permitted by Law. EACH PARTY HERETO (AND BORQS TO THE EXTENT OF ITS THIRD
PARTY BENEFICIARY RIGHTS) HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY WITH RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

 

19.           Specific
Performance. Each party acknowledges that the rights of each party to consummate the transactions contemplated by this Agreement
are unique, recognizes and affirms that in the event of a breach of this Agreement by any party, money damages may be inadequate
and the non-breaching party (or Borqs) may have not adequate remedy at law, and agree that irreparable damage would occur in the
event that any of the provisions of this Agreement were not performed by an applicable party in accordance with their specific
terms or were otherwise breached. Accordingly, each party (and Borqs as a third party beneficiary) shall be entitled to seek an
injunction or restraining order to prevent breaches of this Agreement and to seek to enforce specifically the terms and provisions
hereof, without the requirement to post any bond or other security or to prove that money damages would be inadequate, this being
in addition to any other right or remedy to which such party may be entitled under this Agreement, at law or in equity.

 

20.           Severability.
In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction, such provision shall
be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable,
and the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired
thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon
such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties will substitute
for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out, so far as may be valid,
legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

 

    	 	15	 

     

    

 

21.           Entire
Agreement. This Agreement and the Registration Rights Agreement, and to the extent incorporated herein, the Merger Agreement,
constitutes the entire agreement of the Subscriber and the Company relating to the matters contained herein and therein, superseding
all prior contracts or agreements relating to such matters, whether oral or written. Notwithstanding the foregoing, this Section
21 shall not affect any confidentiality obligations of the Subscriber to the Company or Borqs pursuant to any confidentiality
agreements entered into by the Subscriber prior to the date hereof.

 

22.           Interpretation.
The headings, titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing
or interpreting this Agreement. In this Agreement, unless the context otherwise requires: (i) any pronoun used in this Agreement
shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall
include the plural and vice versa; (ii) “including” (and with correlative meaning “include”) means including
without limiting the generality of any description preceding or succeeding such term and shall be deemed in each case to be followed
by the words “without limitation”; (iii) the words “herein,” “hereto,” and “hereby”
and other words of similar import in this Agreement shall be deemed in each case to refer to this Agreement as a whole and not
to any particular section or other subdivision of this Agreement; and (iv) the term “Dollars” or “$” means
United States dollars. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently,
in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly
by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship
of any provision of this Agreement.

 

23.           Counsel.
The Subscriber hereby acknowledges that the Company and its counsel represent the interests of the Company and not those of the
Subscriber in any agreement (including this Agreement) to which the Company is a party.

 

24.           Further
Assurances. From time to time, at another party's request and without further consideration (but at the requesting party's
reasonable cost and expense), each party shall execute and deliver such additional documents and take all such further action
as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

 

25.           Counterparts;
Facsimile. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall
be deemed to be an original and all of which together shall be deemed to be one and the same agreement. A facsimile or other electronic
transmission of this signed Agreement shall be legal and binding on all parties hereto.
