2 Assumptions

The following opinions are given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion letter. These opinions only relate to the laws of the British Virgin Islands which are in force on the date of this opinion letter. In giving the following opinions we have relied (without further verification) upon the completeness and accuracy of the Register of Members, the Director’s Certificate and the Certificate of Good Standing. We have also relied upon the following assumptions, which we have not independently verified:

2.1 Copy documents or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals.

2.3 There is nothing under any law (other than the law of the British Virgin Islands) which would or might affect the opinions set out below.

3 Opinion

Based upon the foregoing and subject to the qualifications set out below and having regard to such legal considerations as we deem relevant, we are of the opinion that:

3.1 The Company is a company limited by shares incorporated with limited liability under the BVI Business Companies Act (as amended) of the British Virgin Islands (the “Act”), is in good standing at the Registry of Corporate Affairs and validly exists under the laws of the British Virgin Islands.

4 Qualifications

Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions the subject of this opinion.

As a matter of British Virgin Islands law, a share is only issued when it has been entered in the register of members (shareholders). Under section 42 of the Act, the entry of the name of a person in the register of members of a company as a holder of a share in a company is prima facie evidence that legal title in the share vests in that person. A third party interest in the shares in question would not appear. An entry in the register of members may yield to a court order for rectification (for example, in the event of inaccuracy or omission).

In this opinion the phrase “non-assessable” means, with respect to the issuance of shares, that a shareholder shall not, in respect of the relevant shares, have any obligation to make further contributions to the Company’s assets (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our name under the heading, “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.

Yours faithfully

Dear Sirs

Borqs Technologies, Inc. (the “Company”)

I, the undersigned, being a director of the Company, am aware that you are being asked to provide a legal opinion in relation to certain aspects of British Virgin Islands law (the “Opinion”). Unless otherwise defined herein, capitalised terms used in this certificate have the meaning given to them in the Opinion. I hereby certify that:

2 The Resolutions were duly passed in the manner prescribed in the Memorandum and Articles of the Company, including as to the disclosure of any director’s interests in the Transaction Documents, and have not been amended, varied or revoked in any respect. The issue and allotment of the Offer Shares, the Warrant Shares and the Option Shares pursuant to the Proposed Sale is appropriate to fulfill the intent of the Resolutions and shall not cause any restriction or limitation set out in the Resolutions to be exceeded.

3 The members of the Company (the “Members”) have not restricted or limited the powers of the directors of the Company in any way.

4 The directors of the Company at the date of the resolutions are as follows:

Pat Sek Yuen Chan

Yaqi Feng

Joseph Wai Leung Wong

5 There is nothing contained in the Company’s register of members, minute book or other corporate records, which you have not inspected, which would or might affect the Opinion.

6 All of the Selling Shares are fully paid and non-assessable.

7 The issuance of the Selling Shares by the Company was duly authorised.

8 Prior to, at the time of, and immediately following execution of the Transaction Documents the Company was, or will be, able to pay its debts as they fell, or fall, due, and the transactions to which the Transaction Documents relate will not cause the Company to become unable to pay its debts as they fall due. The Company has entered, or will enter, into the Transaction Documents for proper value, not with an intention to defraud or wilfully defeat an obligation owed to any creditor and the transactions contemplated thereby do not and will not give any creditor an unfair preference.

9 Neither the Company nor any of its subsidiaries (if any) has an interest in any land in the British Virgin Islands.

10 Each director of the Company considers the transactions contemplated by the Transaction Documents to be of commercial benefit to the Company and has acted in good faith in the best interests of the Company, and for a proper purpose of the Company, in relation to the transactions which are the subject of the Opinion.

I confirm that you may continue to rely on this certificate as being true and correct on the day that you issue the Opinion, unless I shall have previously notified you in writing personally to the contrary.
