Description of the Registrants Securities

Exhibit 4.5

DESCRIPTION OF SECURITIES

The following summary of the material terms of the securities of PTK Acquisition Corporation (“we,” “us,” “our” or “the company”) is not intended to be a complete summary of the rights and preferences of such securities and is subject to and qualified by reference to our amended and restated memorandum and articles of association incorporated by reference as an exhibit to the company’s Annual Report on Form 10-K for the year ended December 31, 2020, and applicable law. We urge you to read our amended and restated memorandum and articles of association in their entirety for a complete description of the rights and preferences of our securities.

Certain Terms

Unless otherwise stated in this Exhibit or the context otherwise requires, references to:

General

Our certificate of incorporation currently authorizes the issuance of 100,000,000 shares of common stock, par value $0.0001 and we filed an amended and restated certificate of incorporation prior to the completion of the Initial Public Offering authorizing 1,000,000 shares of undesignated preferred stock, $0.0001 par value. No shares of preferred stock are currently outstanding. The following description summarizes all of the material terms of our securities. Because it is only a summary, it may not contain all the information that is important to you. For a complete description you should refer to our amended and restated certificate of incorporation, bylaws, and the forms of warrant agreement, which are filed with the SEC. The following description summarizes certain terms of our shares as set out more particularly in our amended and restated memorandum and articles of association. Because it is only a summary, it may not contain all the information that is important to you.

Units

Each unit has an offering price of $10.00 and consists of one share of common stock and one redeemable warrant. Each redeemable warrant entitles the holder thereof to purchase one half of one share of common stock. Each redeemable warrant has an exercise price $11.50 per whole share and shall expire on the five year anniversary of the effective date of the registration statement of which this Annual Report on Form 10-K forms a part. In addition, we will not issue fractional shares. As a result, you must exercise warrants in multiples of two warrants, at a price of $11.50 per full share, subject to adjustment as described in this Annual Report on Form 10-K, to validly exercise your warrants.

The common stock and warrants comprising the units began separate trading on September 23, 2020. Holders now have the option to continue to hold units or separate their units into the component pieces. Holders will need to have their brokers contact our transfer agent in order to separate the units into shares of common stock and warrants.

Common Stock

Our holders of record of our common stock are entitled to one vote for each share held on all matters to be voted on by stockholders. In connection with any vote held to approve our initial business combination, our insiders, officers and directors, have agreed to vote their respective shares of common stock owned by, including both the insider shares and any shares acquired in the Initial Public Offering or in the open market, in favor of the proposed business combination.

We will consummate our initial business combination only if public stockholders do not exercise conversion rights in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of the initial business combination and a majority of the outstanding shares of common stock voted are voted in favor of the business combination.

Pursuant to our amended and restated certificate of incorporation, if we do not consummate our initial business combination within 18 months from the Initial Public Offering, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject (in the case of (ii) and (iii) above) to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our insiders have agreed to waive their rights to share in any distribution with respect to their insider shares, although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within the prescribed time period.

Our stockholders have no conversion, preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to the shares of common stock, except that public stockholders have the right to sell their shares to us in any tender offer or have their shares of common stock converted to cash equal to their pro rata share of the trust account if they vote on the proposed business combination and the business combination is completed. If we hold a stockholder vote to amend any provisions of our certificate of incorporation relating to stockholder’s rights or pre-business combination activity (including the substance or timing within which we have to complete a business combination), we will provide our public stockholders with the opportunity to redeem their shares of common stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our franchise and income taxes, divided by the number of then outstanding public shares, in connection with any such vote. In either of

2

such events, converting stockholders would be paid their pro rata portion of the trust account promptly following consummation of the business combination or the approval of the amendment to the certificate of incorporation. Public stockholders who sell or convert their stock into their share of the trust account still have the right to exercise the warrants that they received as part of the units. If the business combination is not consummated or the amendment is not approved, stockholders will not be paid such amounts.

Insider Shares

The insider shares are identical to the shares of common stock, and our insiders have the same stockholder rights as public stockholders, except that (i) the insider shares are subject to certain transfer restrictions, as described in more detail below and (ii) our insiders have agreed (A) to vote their insider shares and any public shares acquired in or after the Initial Public Offering in favor of any proposed business combination, (B) not to propose, or vote in favor of, (x) an amendment to our certificate of incorporation that would affect the substance or timing of our obligation to redeem 100% of our public shares if we do not complete our initial business combination within 18 months from the Initial Public Offering or (y) which adversely affects the rights of our public stockholders, unless we provide our public stockholders with the opportunity to redeem their shares of common stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, net of taxes payable, divided by the number of then outstanding public shares, (C) not to convert any shares (including the insider shares) into the right to receive cash from the trust account in connection with a stockholder vote to approve our proposed initial business combination (or sell any shares they hold to us in a tender offer in connection with a proposed initial business combination) or a vote to amend the provisions of our certificate of incorporation relating to the substance or timing of our obligation to redeem 100% of our public shares if we do not complete our initial business combination within 18 months from the Initial Public Offering, and (D) that the insider shares shall not be entitled to be redeemed for a pro rata portion of the funds held in the trust account if a business combination is not consummated.

The insider shares were placed into an escrow account maintained in New York, New York by Continental Stock Transfer & Trust Company, acting as escrow agent. Subject to certain limited exceptions, 50% of these shares will not be transferred, assigned, sold or released from escrow until the earlier of six months after the date of the consummation of our initial business combination and the date on which the closing price of our common stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the consummation of our initial business combination and the remaining 50% of the insider shares will not be transferred, assigned, sold or released from escrow until six months after the date of the consummation of our initial business combination, or earlier, in either case, if, subsequent to our initial business combination, we complete a liquidation, merger, stock exchange or other similar transaction which results in all of our stockholders having the right to exchange their shares of common stock for cash, securities or other property. The limited exceptions referred to above include (1) transfers among the insiders, to our officers, directors, advisors and employees, (2) transfers to an insider’s affiliates or its members upon its liquidation, (3) transfers to relatives and trusts for estate planning purposes, (4) transfers by virtue of the laws of descent and distribution upon death, (5) transfers pursuant to a qualified domestic relations order, (6) private sales made at prices no greater than the price at which the securities were originally purchased or (7) transfers to us for cancellation in connection with the consummation of an initial business combination, in each case (except for clause 7) where the transferee agrees to the terms of the escrow agreement and forfeiture, as the case may be, as well as the other applicable restrictions and agreements of the holders of the insider shares.

Preferred Stock

There are no shares of preferred stock outstanding. Our certificate of incorporation filed with the State of Delaware authorizes the issuance of 1,000,000 shares of preferred stock with such designation, rights and preferences as may be determined from time to time by our board of directors. No shares of preferred stock are being issued or registered as of the date of this Annual Report on Form 10-K. Accordingly, our board of directors

3

is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of common stock. However, the underwriting agreement prohibits us, prior to a business combination, from issuing preferred stock which participates in any manner in the proceeds of the trust account, or which votes as a class with the common stock on our initial business combination. We may issue some or all of the preferred stock to effect our initial business combination. In addition, the preferred stock could be utilized as a method of discouraging, delaying or preventing a change in control of us. Although we do not currently intend to issue any shares of preferred stock, we reserve the right to do so in the future.

Redeemable Warrants

Public Warrants

Each redeemable warrant entitles the registered holder to purchase one half of one share of common stock at a price of $11.50 per full share, subject to adjustment as discussed below, at any time commencing on the later of the completion of an initial business combination and 12 months from the date of the Initial Public Offering. Because the warrants may only be exercised for whole numbers of shares, only an even number of warrants may be exercised at any given time. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares. This means that only an even number of warrants may be exercised at any given time by a warrant holder. However, except as set forth below, no warrants will be exercisable for cash unless we have an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. The warrants will expire five years from the consummation of a Business Combination at 5:00 p.m., Eastern Standard Time.

We may call the outstanding warrants for redemption (excluding the private warrants and warrants underlying the units that may be issued upon conversion of working capital loans), in whole and not in part, at a price of $0.01 per warrant:

The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.

The redemption criteria for our warrants have been established at a price which is intended to provide warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then-prevailing share price and the warrant exercise price so that if the share price declines as a result of our redemption call, the redemption will not cause the share price to drop below the exercise price of the warrants.

If we call the warrants for redemption as described above, our management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants,

4

multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of our common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. Whether we will exercise our option to require all holders to exercise their warrants on a “cashless basis” will depend on a variety of factors including the price of our common stock at the time the warrants are called for redemption, our cash needs at such time and concerns regarding dilutive share issuances.

In addition, if (x) we issue additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at an issue price or effective issue price of less than $9.50 per share of common stock (with such issue price or effective issue price to be determined in good faith by our board of directors), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination, and (z) the market price is below $9.50 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the market price, and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the market value.

The warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the holders of a majority of the then outstanding warrants in order to make any change that adversely affects the interests of the registered holders.

The exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or our recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuances of shares of common stock at a price below their respective exercise prices.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of common stock and any voting rights until they exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Except as described above, no public warrants will be exercisable for cash and we will not be obligated to issue shares of common stock unless at the time a holder seeks to exercise such warrant, a prospectus relating to the shares of common stock issuable upon exercise of the warrants is current and the shares of common stock have been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. Under the terms of the warrant agreement, we have agreed to use our best efforts to meet these conditions and to maintain a current prospectus relating to the shares of common stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so and, if we do not maintain a current prospectus relating to the shares of common stock issuable upon exercise of the warrants, holders will be unable to exercise their warrants and we will not be required to settle any such warrant exercise. If the prospectus relating to the shares of common stock issuable upon the exercise of the warrants is not current or if the common stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, we will not be required to net cash settle or cash settle the warrant exercise, the warrants may have no value, the market for the warrants may be limited and the warrants may expire worthless.

5

Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.9% of the shares of common stock outstanding. Notwithstanding the foregoing, any person who acquires a warrant with the purpose or effect of changing or influencing the control of our company, or in connection with or as a participant in any transaction having such purpose or effect, immediately upon such acquisition will be deemed to be the beneficial owner of the underlying shares of common stock and not be able to take advantage of this provision.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of shares of common stock to be issued to the warrant holder.

An exchange offer made to both the publicly traded warrants and the warrants held by our sponsor on the same terms will not constitute an amendment requiring consent of any warrant holder.

Private Warrants

We have agreed that so long as the private warrants are still held by the initial purchasers or their affiliates, we will not redeem such warrants and we will allow the holders to exercise such warrants on a cashless basis (even if a registration statement covering the shares of common stock issuable upon exercise of such warrants is not effective). However, once any of the foregoing warrants are transferred from the initial purchasers or their affiliates, these arrangements will no longer apply. Additionally, the representative of the underwriters has agreed that it will not be permitted to exercise any private warrants to be issued to it and/or its designees upon consummation of the Initial Public after the five year anniversary of the effective date of the registration statement of which this Annual Report on Form 10-K forms a part. Furthermore, because the private warrants will be issued in a private transaction, the holders and their transferees will be allowed to exercise the private warrants for cash even if a registration statement covering the shares of common stock issuable upon exercise of such warrants is not effective and receive unregistered shares of common stock.

Dividends

We have not paid any cash dividends on our shares of common stock to date and do not intend to pay cash dividends prior to the completion of a business combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to completion of a business combination. The payment of any dividends subsequent to a business combination will be within the discretion of our then board of directors. It is the present intention of our board of directors to retain all earnings, if any, for use in our business operations and, accordingly, our board does not anticipate declaring any dividends in the foreseeable future.

Our Transfer Agent and Warrant Agent

The transfer agent for our securities, warrant agent for our warrants is Continental Stock Transfer & Trust Company, 1 State Street, 30th Floor, New York, NY 10004-1561.

Certain Anti-Takeover Provisions of Delaware Law and our Amended and Restated Certificate of Incorporation and By-Laws

We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

6

A “business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section 203 do not apply if:

Exclusive Forum For Certain Lawsuits

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (1) derivative action or proceeding brought on behalf of our company, (2) action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of our company to our company or our stockholders, or any claim for aiding and abetting any such alleged breach, (3) action asserting a claim against our company or any director or officer of our company arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or our bylaws, or (4) action asserting a claim against us or any director or officer of our company governed by the internal affairs doctrine except for, as to each of (1) through (4) above, any claim (A) as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or (C) arising under the federal securities laws, including the Securities Act as to which the Court of Chancery and the federal district court for the District of Delaware shall concurrently be the sole and exclusive forums. Notwithstanding the foregoing, the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers. Furthermore, the enforceability of choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable.

Special Meeting of Stockholders

Our amended and restated certificate of incorporation and bylaws provide that special meetings of our stockholders may be called only by a majority vote of our board of directors, by our chief executive officer or by our chairman.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our amended and restated certificate of incorporation and bylaws provides that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at

7

our annual meeting of stockholders must provide timely notice of their intent in writing. To be timely, a stockholder’s notice will need to be delivered to our principal executive offices not later than the close of business on the 90th day nor earlier than the opening of business on the 120th day prior to the scheduled date of the annual meeting of stockholders. Our bylaws also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

Authorized but Unissued Shares

Our authorized but unissued common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Action by Written Consent

Subsequent to the consummation of the offering, any action required or permitted to be taken by our common stockholders must be effected by a duly called annual or special meeting of such stockholders and may not be effected by written consent of the stockholders.

Classified Board of Directors

Our board of directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. Our amended and restated certificate of incorporation will provide that the authorized number of directors may be changed only by resolution of the board of directors. Subject to the terms of any preferred stock, any or all of the directors may be removed from office at any time, but only for cause and only by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class. Any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

SHARES ELIGIBLE FOR FUTURE SALE

Immediately after the Initial Public Offering, we had 14,375,000 shares of common stock outstanding. Of these shares, the 11,500,000 shares of common stock sold in the Initial Public Offering, are freely tradable without restriction or further registration under the Securities Act, except for any shares purchased by one of our affiliates within the meaning of Rule 144 under the Securities Act. All of the remaining shares are restricted securities under Rule 144, in that they were issued in private transactions not involving a public offering.

Rule 144

A person who has beneficially owned restricted shares of common stock for at least six months would be entitled to sell their shares provided that (1) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (2) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale. Persons who have beneficially owned restricted shares of common stock for at least six months but who are our affiliates at the time of, or any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period a number of shares that does not exceed the greater of either of the following:

8

Sales under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

As a result, it is likely that pursuant to Rule 144, our insiders will be able to sell their insider shares freely without registration one year after we have completed our initial business combination assuming they are not an affiliate of ours at that time.

Registration Rights

The holders of our insider shares issued and outstanding on the date of the Initial Public Offering, as well as the holders of any shares our insiders, officers, directors or their affiliates may be issued in payment of working capital loans made to us, will be entitled to registration rights pursuant to an agreement to be signed contemporaneously with the Initial Public Offering. The holders of a majority of these securities are entitled to make up to two demands that we register such securities. The holders of the majority of the insider shares can elect to exercise these registration rights at any time commencing three months prior to the date on which these shares of common stock are to be released from escrow. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to our consummation of our initial business combination. We will bear the expenses incurred in connection with the filing of any such registration statements.

Resale Restrictions

We are distributing our securities in the Province of Ontario, Canada (the “Canadian Offering Jurisdiction”) by way of a private placement and exempt from the requirement that we prepare and file a prospectus with the securities regulatory authorities in such Canadian Offering Jurisdiction. Any resale of our securities in Canada must be made under applicable securities laws that will vary depending on the relevant jurisdiction, and which may require resales to be made under available statutory exemptions or under a discretionary exemption granted by the applicable Canadian securities regulatory authority. Canadian resale restrictions in some circumstances may apply to resales of interests made outside of Canada. Canadian purchasers are advised to seek legal advice prior to any resale of our securities. We may never be a “reporting issuer”, as such term is defined under applicable Canadian securities legislation, in any province or territory of Canada in which our securities will be offered and there currently is no public market for any of the securities in Canada, and one may never develop. Canadian investors are advised that we have no intention to file a prospectus or similar document with any securities regulatory authority in Canada qualifying the resale of the securities to the public in any province or territory in Canada.

Representations of Purchasers

A Canadian purchaser will be required to represent to us and the dealer from whom the purchase confirmation is received that:

Rights of Action — Ontario Purchasers Only

Under Ontario securities legislation, certain purchasers who purchase a security during the period of distribution will have a statutory right of action for damages, or while still the owner of our securities, for rescission against us in the event that our SEC filings contain a misrepresentation without regard to whether the purchaser relied on the misrepresentation. The right of action for damages is exercisable not later than the earlier of 180 days from the date the purchaser first had knowledge of the facts giving rise to the cause of action and three years from the date on which payment is made for our securities. The right of action for rescission is exercisable not later than 180 days from the date on which payment is made for our securities. If a purchaser elects to exercise the right of action for rescission, the purchaser will have no right of action for damages against us. In no case will the amount recoverable in any action exceed the price at which our securities were offered to the purchaser and if the purchaser is shown to have purchased the securities with knowledge of the misrepresentation, we will have no liability. In the case of an action for damages, we will not be liable for all or any portion of the damages that are proven to not represent the depreciation in value of our securities as a result of the misrepresentation relied upon. These rights are in addition to, and without derogation from, any other rights or remedies available at law to an Ontario purchaser. The foregoing is a summary of the rights available to an Ontario purchaser. Ontario purchasers should refer to the complete text of the relevant statutory provisions.

Enforcement of Legal Rights

All of our directors and officers as well as the experts named herein are located outside of Canada and, as a result, it may not be possible for Canadian purchasers to effect service of process within Canada upon us or those persons. All of our assets and the assets of those persons are located outside of Canada and, as a result, it may not be possible to satisfy a judgment against us or those persons in Canada or to enforce a judgment obtained in Canadian courts against us or those persons outside of Canada.

Collection of Personal Information

If a Canadian purchaser is resident in or otherwise subject to the securities laws of the Province of Ontario, the Purchaser authorizes the indirect collection of personal information pertaining to the Canadian purchaser by the Ontario Securities Commission (the “OSC”) and each Canadian purchaser will be required to acknowledge and agree that the Canadian purchaser has been notified by us (i) of the delivery to the OSC of personal information pertaining to the Canadian purchaser, including, without limitation, the full name, residential address and telephone number of the Canadian purchaser, the number and type of securities purchased and the total purchase price paid in respect of the securities, (ii) that this information is being collected indirectly by the OSC under the authority granted to it in securities legislation, (iii) that this information is being collected for the purposes of the administration and enforcement of the securities legislation of Ontario, and (iv) that the title, business address and business telephone number of the public official in Ontario who can answer questions about the OSC’s indirect collection of the information is the Administrative Assistant to the Director of Corporate Finance, the Ontario Securities Commission, Suite 1903, Box 5520, Queen Street West, Toronto, Ontario, M5H 3S8, Telephone: (416) 593-8086, Facsimile: (416) 593-8252.

Notice to Proposed Investors in Hong Kong

The units may not be offered or sold in Hong Kong by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap. 32, Laws of Hong Kong), or (ii) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap. 32, Laws of Hong Kong) and no advertisement, invitation or document relating to the units may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the laws of Hong Kong) other than with respect to units which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

The contents of this document have not been reviewed by any regulatory authority in Hong Kong. You are advised to exercise caution in relation to the offer. If you are in any doubt about any of the contents of this document, you should obtain independent professional advice.
