Section 2.1 or in Section 2.2, be stamped or otherwise imprinted with a legend substantially in the following form: 

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, THE SECURITIES ACT (ONTARIO) OR ANY STATE OR PROVINCIAL SECURITIES LAWS
AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN REGISTERED UNDER SUCH ACT AND ALL SUCH APPLICABLE LAWS OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE. UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY
MUST NOT TRADE THE SECURITY BEFORE THE DATE THAT IS 4 MONTHS AND A DAY AFTER THE LATER OF (i) [INSERT THE DISTRIBUTION DATE], AND (ii) THE DATE THE ISSUER BECAME A REPORTING ISSUER IN ANY PROVINCE OR TERRITORY.

 A certificate shall not bear such legend if in the opinion of counsel satisfactory to the Company (it being
agreed that Goodwin Procter LLP and Stikeman Elliott LLP shall be satisfactory) the securities represented thereby may be publicly sold without registration under the Securities Act, Canadian Securities Laws and any applicable state securities
laws. 
 2.2 Notice of Proposed Transfer. Prior to any proposed transfer of any Preferred Shares (other than under the circumstances
described in Sections 2.3, 2.4 or 2.5), and subject to compliance with all applicable provisions in the Shareholders Agreement, the holder thereof shall give written notice to the Company of its intention to effect such
transfer. Each such notice shall describe the manner of the proposed transfer and, if requested by the Company, shall be accompanied by a written opinion of counsel satisfactory to the Company (it being agreed that Goodwin Procter LLP and Stikeman
Elliott LLP shall be satisfactory) to the effect that the proposed transfer may be effected without registration under the Securities Act, Canadian Securities Laws and any applicable state securities laws, whereupon the holder of such stock shall be
entitled under the securities laws to transfer such stock in accordance with the terms of its notice; provided, however, that no such opinion of counsel shall be required for a transfer to one or more partners of the transferor (in the
case of a transferor that is a partnership), one or more members of the transferor (in the case of a transferor that is a limited liability company) or to an affiliated corporation (in the case of a transferor that is a corporation). Each
certificate representing Preferred Shares or Restricted Shares transferred as above provided shall bear the legend set forth in Section 2.1, except that such certificate shall not bear such legend if (i) such transfer is in
accordance with the provisions of Rule 144 (or any other rule permitting public sale without registration under the Securities Act) or (ii) the written opinion of counsel referred to above is to the further effect that the transferee and
any subsequent transferee (other than an affiliate of the Company) would be entitled to transfer such securities in a public sale without registration under the Securities Act. The restrictions provided for in this Section 2.2 shall not
apply to securities which are not required to bear the legend prescribed by Section 2.1 in accordance with the provisions of Section 2.1. 

2.3 Required Registration. 

(a) At any time after six (6) months after the closing of the Company’s Initial Public Offering, the Investors who in the
aggregate hold at least a majority of the total Restricted Shares then outstanding may by written notice to the Company request the Company to register under the Securities Act or applicable Canadian Securities Laws all or any portion of the
Restricted Shares held by such requesting holder or holders for sale in the manner specified in such notice, provided that the reasonably anticipated aggregate price to the public of such public offering would not be less than USD$10,000,000.
For purposes of this Section 2.3 and Sections 2.4 and 2.5, the term “Restricted Shares” shall be deemed to include (but without double counting) the number of Restricted Shares which would be issuable
to a holder of Preferred Shares upon conversion of all Preferred Shares held by such holder at such time; and provided, however, that, in any underwritten public offering contemplated by this Section 2.3 or
Sections 2.4 and 2.5, the holders of Preferred Shares shall be entitled to sell such Preferred Shares to the underwriters (with the underwriters’ approval) for conversion and sale of the Common Shares issued upon conversion
thereof.

 (b) Following receipt of a notice under Section 2.3(a), the Company shall
promptly notify the Investors from whom notice has not been received. The Company shall use reasonable best efforts to register under the Securities Act or Canadian Securities Laws (as applicable), for public sale in accordance with the method of
disposition specified in any notice from requesting holders, the number of Restricted Shares specified in such notice (and in all notices received by the Company from other Investors within thirty (30) days after the giving of such notice by
the Company). If such method of disposition shall be an underwritten public offering, the holders of a majority of the Restricted Shares to be sold in such offering shall designate the managing underwriter of such offering, subject to the approval
of the Company, which shall not be unreasonably withheld or delayed. The Company’s obligation to register, pursuant to this Section 2.3, Restricted Shares on a Registration Statement shall be deemed satisfied only when a
Registration Statement covering all Restricted Shares specified in notices received as aforesaid, for sale in accordance with the method of disposition specified by the requesting holders, shall have become effective and, if such method of
disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto. 
 (c) In any
Registration Statement requested pursuant to this Section 2.3, the Company shall be entitled to include, for sale in accordance with the method of disposition specified by the requesting holders, Common Shares to be sold by the Company
for its own account. If such method of disposition shall be an underwritten public offering and in the opinion of the managing underwriter such inclusion would adversely affect the marketing of the Restricted Shares to be sold, then the Company
shall reduce the number of Common Shares to be sold by the Company for its own account to that number which, in the opinion of the managing underwriter, would not adversely affect the marketing of the Restricted Shares requested to be sold. Except
for as provided in Section 2.3(b), the Company shall not file with the Commission any other Registration Statement with respect to its Common Shares, whether for its own account or that of other stockholders, from the date of receipt of
a notice from requesting holders pursuant to this Section 2.3 until the completion of the period of distribution contemplated thereby. 

(d) Investors are entitled to a maximum of two (2) registrations pursuant to this Section 2.3. 

2.4 Incidental Registration. If the Company at any time (other than pursuant to Section 2.3 or Section 2.5)
proposes to register any of its securities under the Securities Act or Canadian Securities Laws (as applicable) for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to
Registration Statements not available for registering the Restricted Shares for sale to the public or in connection with a Rule 145 transaction), including in the Company’s Initial Public Offering, each such time it will give written notice to
all Investors of its intention so to do. Upon the written request of any Investor, received by the Company within thirty (30) days after the giving of any such notice by the Company, to register any of its Restricted Shares, the Company will
use reasonable best efforts to cause the Restricted Shares as to which registration shall have been so requested to be 








  Investor Rights Agreement — Page

included in the securities to be covered by the Registration Statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition by the holder of
such Restricted Shares so registered. In the event that any registration pursuant to this Section 2.4 shall be, in whole or in part, an underwritten public offering of Common Shares, and the managing underwriter determines in good faith
that the inclusion of all shares requested to be registered would adversely affect the offering, the number of shares that may be included in the underwriting shall be allocated (i) first, to the Company and (ii) second, to the Investors
requesting to register shares in such underwritten public offering on a pro rata basis based on the total number of Restricted Shares held by the Investors requesting to register shares in such underwritten public offering; and third, to any other
stockholder of the Company on a pro-rata basis; provided, however, that in no event may less than twenty percent (20%) of the total number of Common Shares to be included in such underwriting, other than the Company’s Initial
Public Offering, be made available for Restricted Shares. Notwithstanding the foregoing provisions, the Company may withdraw any Registration Statement referred to in this Section 2.4 without thereby incurring any liability to the
holders of Restricted Shares. 
 2.5 Registration on Form S-3 or F-3; Special Provision Relating to Canadian Offerings. 

(a) If at any time (i) one or more Investors who holds Restricted Shares request that the Company file a Registration Statement on
Form S-3 or Form F-3 or any successors thereto for a public offering of all or any portion of the Restricted Shares held by such requesting holder or holders, the reasonably anticipated aggregate price to the public which would not be less than
USD$5,000,000, and (ii) the Company is a registrant entitled to use Form S-3 or Form F-3 or any successors thereto to register such shares, then the Company shall use reasonable best efforts to register under the Securities Act on
Form S-3 or Form F-3 or any successors thereto, for public sale in accordance with the method of disposition specified in such notice, the number of Restricted Shares specified in such notice. Whenever the Company is required by this
Section 2.5 to use reasonable best efforts to effect the registration of Restricted Shares, each of the procedures and requirements of Section 2.3 (including but not limited to the requirement that the Company notify all
Investors from whom notice has not been received and provide them with the opportunity to participate in the offering) shall apply to such registration; provided, however, that there shall be no limitation on the number of
registrations on Form S-3 or Form F-3 which may be requested and obtained under this Section 2.5 (except that that number of such registrations that may be requested in any one-year period is limited to two (2)); and provided
further, however, that in any Registration Statement requested pursuant to this Section 2.5, the Company shall be entitled to include for sale in accordance with the method of disposition specified by the requesting holders,
Common Shares to be sold by the Company for its own account, except as and to the extent that, if such method of disposition shall be an underwritten public offering, in the opinion of the managing underwriter such inclusion would adversely affect
the marketing of the Restricted Shares to be sold. 
 (b) In addition to the other registration rights herein, the Company hereby grants to
the Investors who hold Restricted Shares registration rights with respect to required, incidental and short-form registrations in Canada, which rights shall be substantially equivalent to, and subject to the same limitations as, those set forth in
Sections 2.3, 2.4 and 2.5 of this Agreement

with all appropriate changes in recognition of the differences between U.S. and Canadian offerings and the differences between U.S. and Canadian Securities Laws. The other provisions of this
Agreement shall also apply to such Canadian offerings and registration rights, again with appropriate changes. 
 2.6 Limitations.
The Company shall not be required to effect any registration within one hundred twenty (120) days after the effective date of any other Registration Statement covering a firm commitment underwritten public offering in which the holders of
Restricted Shares shall have been entitled to join pursuant to Section 2.4 and in which there shall have been effectively registered all Restricted Shares as to which registration shall have been requested (subject, in the case of a
registration pursuant to Section 2.4, to the underwriter cutbacks permitted therein). If at the time of any request to register Restricted Shares by Investors pursuant to Section 2.3 or 2.5, the Company is engaged or
has plans to engage in a registered public offering or is engaged in any other activity which, in the good faith determination of the Company’s Board of Directors, would be adversely affected by the requested registration, then the Company may
at its option direct that such request be delayed for a period not in excess of ninety (90) days from the date of such request, such right to delay a request to be exercised by the Company not more than once in any twelve (12)-month period.

 2.7 Registration Procedures. If and whenever the Company is required by the provisions of Sections 2.3, 2.4 or
2.5 to use reasonable best efforts to effect the registration of any Restricted Shares under the Securities Act, the Company will, as expeditiously as possible: 

(a) prepare and file with the Commission a Registration Statement (which, in the case of an underwritten public offering pursuant to
Section 2.3, shall be on Form S-1, Form F-1 or Form F-10 or other form of general applicability satisfactory to the managing underwriter selected as therein provided) with respect to such securities and use reasonable best efforts to
cause such Registration Statement to become and remain effective for the period of the distribution contemplated thereby (determined as hereinafter provided); 

(b) prepare and file with the Commission such amendments and supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective for the period specified in paragraph (a) above and comply with the provisions of the Securities Act with respect to the disposition of all Restricted Shares covered by
such Registration Statement in accordance with the sellers’ intended method of disposition set forth in such Registration Statement for such period; 

(c) furnish to each seller of Restricted Shares and to each underwriter such number of copies of the Registration Statement and the prospectus
included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Restricted Shares covered by such Registration Statement; 

(d) use reasonable best efforts to register or qualify the Restricted Shares covered by such Registration Statement under the securities or
“blue sky” laws of such jurisdictions as the sellers of Restricted Shares or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; provided, however, that the Company shall

not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction; 
 (e) use reasonable best efforts to list the Restricted Shares covered by such Registration Statement
with any securities exchange or over-the-counter market on which the Common Shares of the Company is then listed or quoted, as the case may be; 

(f) promptly provide a transfer agent and registrar for all such Restricted Shares not later than the effective date of such Registration
Statement; 
 (g) immediately notify each seller of Restricted Shares and each underwriter under such Registration Statement, at any time
when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing (it being understood that
the sellers of Restricted Shares agree upon receipt of such notice forthwith to cease making offers and sales of Restricted Shares pursuant to such Registration Statement or deliveries of the prospectus contained therein for any purpose until the
Company has prepared and furnished such amendment or supplement to the prospectus as may be necessary so that, as thereafter delivered to purchasers of such Restricted Shares, such prospectus shall not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing); 

(h) if the offering is underwritten and at the request of any seller of Restricted Shares, use reasonable best efforts to furnish on the date
that Restricted Shares is delivered to the underwriters for sale pursuant to such registration: (i) an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters, stating
that such Registration Statement has become effective under the Securities Act and substantially to the effect that (A) to the knowledge of such counsel, no stop order suspending the effectiveness thereof has been issued and no proceedings for
that purpose have been instituted or are pending or contemplated under the Securities Act, (B) the Registration Statement, the related prospectus and each amendment or supplement thereof comply as to form in all material respects with the
requirements of the Securities Act (except that such counsel need not express any opinion as to financial statements contained therein), (C) nothing has come to the attention of such counsel during the course of their representation of the
Company that leads them to believe that the Registration Statement, the related prospectus or any amendment or supplement thereof (except as to the financial statements (including the notes thereto) and schedules and other financial and statistical
data contained or incorporated by reference therein as to which such counsel need not express any opinion or belief) at the time the Registration Statement became effective contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements therein not misleading, or that the prospectus as of its date or the date on which the shares being offered are sold to the underwriters, or any later date on which the
underwriters purchase shares subject to 








  Investor Rights Agreement — Page
 9
 
  

 
an over allotment option, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary in order to make
the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that such counsel expresses no comment as to any financial statements (including the notes thereto) and schedules and other
financial or statistical data contained in the Registration Statement, the related prospectus or any amendment or supplement thereof), and (D) to such other effects as are customary and reasonably may be requested by counsel to the underwriters
or by such seller or its counsel (it being understood that if a change in the laws of the United States has occurred, such opinion shall be in a form then customary for an underwritten public offering); and (ii) a letter dated such date from
the independent public accountants retained by the Company, addressed to the underwriters and to such seller, stating that they are independent public accountants within the meaning of the Securities Act and that, in the opinion of such accountants,
the financial statements of the Company included in the Registration Statement or the prospectus, or any amendment or supplement thereof, comply as to form in all material respects with the applicable accounting requirements of the Securities Act,
and such letter shall additionally cover such other financial matters (including information as to the period ending no more than five business days prior to the date of such letter) with respect to such registration as such underwriters reasonably
may request; and 
 (i) make available for inspection by each seller of Restricted Shares upon reasonable notice, any underwriter
participating in any distribution pursuant to such Registration Statement, and any attorney, accountant or other agent retained by such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement. 

For purposes of Sections 2.7(a) and 2.7(b) and of Section 2.3(c), the period of distribution of Restricted
Shares in a firm commitment underwritten public offering shall be deemed to extend until each underwriter has completed the distribution of all securities purchased by it, and the period of distribution of Restricted Shares in any other registration
shall be deemed to extend until the earlier of the sale of all Restricted Shares covered thereby and one hundred twenty (120) days after the effective date thereof. 

In connection with each registration hereunder, the sellers of Restricted Shares will (x) furnish to the Company in writing such
information with respect to themselves, the Restricted Shares held by them and the proposed distribution by them as reasonably requested by the Company and its counsel in connection with such registration, (y) agree to sell Restricted Shares on
the basis provided in any underwriting arrangements, and (z) complete and execute all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents as may be required under the terms of such underwriting
arrangements. 
 In connection with each registration pursuant to Sections 2.3, 2.4 or 2.5 covering an underwritten
public offering, the Company and each seller agree to enter into a written agreement with the managing underwriter selected in the manner herein provided in such form and containing such provisions as are customary in the securities business for
such an arrangement between such underwriter and companies of the Company’s size and investment stature and as are consistent with the terms of this Agreement.

 2.8 Expenses. The Company will pay all Registration Expenses in connection with each
Registration Statement under Sections 2.3, 2.4 or 2.5; provided, however, that if an offering pursuant to any registration commenced pursuant to Sections 2.3 or 2.5 is abandoned and the
Registration Statement withdrawn prior to being declared effective at the request of the selling stockholders (other than by reason, in whole or in part, of a material adverse change in, or adverse information pertaining to, the Company’s
business, affairs, assets, results of operations, financial position, cash flows or prospects that was not known to the selling stockholders prior to the commencement of such registration, in which event the Company shall bear all Registration
Expenses), such selling stockholders shall either bear, in proportion to the number of shares proposed to be sold by each, all Registration Expenses incurred and paid by the Company in conjunction with such registration or shall be deemed to have
exercised their registration rights under the applicable Section. All Selling Expenses in connection with each Registration Statement under Sections 2.3, 2.4 or 2.5 shall be borne by the participating sellers in proportion
to the number of shares sold by each, or by such participating sellers other than the Company (except to the extent the Company shall be a seller) as they may agree. 

2.9 Indemnification and Contribution. 

(a) In the event of a registration of any of the Restricted Shares under the Securities Act pursuant to this Agreement, the Company will
indemnify and hold harmless each seller of such Restricted Shares thereunder, each of its directors, partners and officers, each underwriter of such Restricted Shares thereunder and each other person, if any, who controls such seller or underwriter
within the meaning of the Securities Act or Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act, the Exchange Act,
state or provincial securities or “blue sky” laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement under which such Restricted Shares was registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out
of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse each such seller, each such underwriter
and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this Section 2.9(a) shall not apply to amounts paid in settlement of any such losses, claims, damages or liabilities if such settlement is effected without the consent of the Company, such consent not to be
unreasonably withheld or delayed, nor shall the Company be liable in any such case if and to the extent that any such losses, claims, damages or liabilities arise solely out of or are based solely upon an untrue statement or alleged untrue statement
or omission or alleged omission so made in conformity with information furnished by such seller in writing specifically for use in such Registration Statement or prospectus. 








  Investor Rights Agreement — Page

 (b) In the event of a registration of any of the Restricted Shares under the Securities Act
pursuant to this Agreement, each seller of such Restricted Shares thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of the Securities Act, each
officer of the Company who signs the Registration Statement, each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the Securities Act, against all losses, claims, damages or liabilities,
joint or several, to which the Company or such officer, director, underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement under which such Restricted Shares was registered under the Securities Act pursuant to this Agreement, any
preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and will reimburse the Company and each such officer, director, underwriter and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.9(b) shall not apply to amounts paid in settlement of any such losses, claims, damages or
liabilities if such settlement is effected without the consent of such seller, such consent not to be unreasonably withheld or delayed, nor shall such seller will be liable hereunder in any such case if and only to the extent that any such loss,
claim, damage or liability arises solely out of or is based solely upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as such,
furnished in writing to the Company by such seller specifically for use in such Registration Statement or prospectus; and provided further, however, that the liability of each seller hereunder shall not in any event exceed the net
proceeds received by such seller from the sale of Restricted Shares covered by such Registration Statement. 
 (c) Promptly after receipt by
an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the
omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 2.9 and shall only relieve it from any liability which it may have to such
indemnified party under this Section 2.9 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory to such indemnified party, and, after notice from the
indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.9 for any legal expenses subsequently
incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses 








  Investor Rights Agreement — Page
 12
 
  

 
available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the
interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate
counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. 
 (d) In order to provide
for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any holder of Restricted Shares exercising rights under this Agreement, or any controlling person of any such holder, makes a claim
for indemnification pursuant to this Section 2.9 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of
appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 2.9 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part
of any such selling holder or any such controlling person in circumstances for which indemnification is provided under this Section 2.9; then, and in each such case, the Company and such holder will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that such holder is responsible for the portion represented by the percentage that the public offering price of its Restricted Shares
offered by the Registration Statement bears to the public offering price of all securities offered by such Registration Statement, and the Company is responsible for the remaining portion; provided, however, that, in any such case,
(A) no such holder will be required to contribute any amount in excess of the net proceeds received by such holder from the sale of all such Restricted Shares offered by it pursuant to such Registration Statement; and (B) no person or
entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 

2.10 Changes in Common Shares or Preferred Shares. If, and as often as, there is any change in the Common Shares or the Preferred
Shares by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the
rights and privileges granted hereby shall continue with respect to the Common Shares or the Preferred Shares as so changed. 
 2.11 Rule

Company, and such other reports and documents so filed by the Company as such holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such holder to sell any Restricted Shares without registration. 

2.12 Suspension of Registration Obligation. Notwithstanding the provisions of Section 2.3, the Company’s obligation to
file a Registration Statement, or to cause such Registration Statement to become and remain effective, shall be suspended for a period not to exceed ninety (90) days in any twelve (12)-month period if there exists at the time material
non-public information relating to the Company which, in the reasonable opinion of the Board of Directors of the Company, should not be disclosed. 

2.13 No Third Party Registration Rights. The Company represents and warrants that, there currently are no holders of its capital stock
entitled to registration rights. The Company shall not, without the prior written consent of at least a majority of the then-outstanding Restricted Shares, grant to any third party any registration rights more favorable than or inconsistent with any
of those contained herein, so long as any of the registration rights under this Agreement remains in effect. 
 2.14 Canadian Securities
Law Requirements. With a view to making available the benefits of certain rules and regulations of the Canadian Securities Laws that may at any time permit the sale of the Restricted Shares to the public without the filing of a prospectus, once
a public market exists for the Common Shares, the Company agrees to use reasonable best efforts to:

available, as those terms are understood and defined under the Securities Act (Ontario), at all times after the date the Company becomes a reporting issuer under Canadian Securities Laws; 

(b) file with the appropriate Canadian Securities Laws regulatory authorities in a timely manner all reports and other documents required of
the Company under Canadian Securities Laws (at any time after the date that the Company becomes a reporting issuer under Canadian Securities Laws); and

a reporting issuer and is not in default of any requirement of Canadian Securities Laws (at any time after the date that the Company becomes a reporting issuer under Canadian Securities Laws), (ii) a copy of the most recent annual or quarterly

  Investor Rights Agreement — Page

with the Company’s consent. Each Investor further acknowledges that the receipt by it of such information may result in such Investor having material undisclosed information relating to the
Company which may, inter alia, restrict its ability to trade in securities of the Company. 
 3.2 Right of Participation in Sales by the
Company. 
 (a) For so long as any Preferred Shares remain outstanding, the Company shall, prior to any proposed issuance by the Company
of any of its securities (other than debt securities with no equity feature), offer to each Investor and each Founder (and for the purposes hereof, the term “Founders” shall be deemed to include any Affiliates of a Founder which for
avoidance of doubt, shall include any trust in which the trustees consist solely of the Founders or the beneficiaries of such trust include only the Founders, their immediate family members or a corporation controlled by any of the foregoing) and
each Founder shall have the discretion to allocate any such offered securities acquired pursuant to this Section 3.2 amongst such Affiliates (each Investor and each Founder being an “Offeree”) by written notice (the
“Initial Offer”) the right, for a period of eighteen (18) days (the “Initial Offer Period”), to purchase for cash at an amount equal to the price or other consideration for which such securities are to be
issued, any or all of that number of such securities as shall be equal to the aggregate offered securities multiplied by a fraction, the numerator of which is the number of Common Shares issuable upon the conversion of the Preferred Shares then
owned by such Investor or the number of Common Shares owned by such Founder, as the case may be, and the denominator of which is the aggregate number of Common Shares then held by all of the Offerees (calculated on an as-converted basis) (the amount
of securities each Offeree is entitled to purchase under this Section 3.2 being referred to as such Offeree’s “Pro Rata Fraction”); provided that the participation pursuant to this Section 3.2
shall not apply to securities: 
 (A) issued pursuant to the Purchase Agreement; 

(B) issued upon conversion of any of the Preferred Shares; 

(C) issued as a stock dividend, stock split, split-up or other distribution, provided that the securities issued pursuant to
such stock dividend or subdivision are limited to additional Common Shares;

warrants, options, convertible securities or other rights which are listed in Schedule III of the Stock Purchase Agreement as being outstanding as of the date of this Agreement, in each case, provided such issuance is pursuant to the terms thereof;

 (E) issued solely in consideration for the acquisition (whether by merger or otherwise) by the Company of all or
substantially all the assets of another entity, but only if such issuance is approved in advance by a majority of the outstanding Preferred Shares (for greater certainty, it being acknowledged that acquisitions of USD$5,000,000 or less do not
require the approval of the said majority); 








  Investor Rights Agreement — Page
 17
 
  

 (F) issued to employees, consultants or directors pursuant to stock option,
stock grant, stock purchase or similar plans or arrangements approved by the holders of a majority of the then outstanding Preferred Shares, including without limitation upon the exercise of Options (as defined in the Articles) outstanding as of the
Class A Original Issue Date (as defined in the Articles), up to a maximum of 925,000 shares (or such higher number of shares as approved by the holders of a majority of the then outstanding Preferred Shares); 

(H) upon the exercise of any right issued pursuant to clauses (A) through (G) hereof which was not itself in
violation of the terms of this Section 3.2; and 
 (I) with respect to which (i) the Investors holding
a majority of the Preferred Shares then held by all Investors and (ii) the holders of a majority of the Common Shares then collectively held by the Founders, elect in writing to waive the rights set forth in this Section 3.2. 

(b) The Initial Offer shall describe the securities proposed to be issued by the Company and specify the number, price and payment terms. Each
Offeree may accept the Initial Offer as to the full number of securities offered to it or any lesser number, by written notice thereof given by it to the Company prior to the expiration of the Initial Offer Period, in which event the Company shall
promptly sell and each such Offeree shall buy, upon the terms specified, the number of securities agreed to be purchased by such Offeree. 

(c) In the event an Offeree does not wish to exercise its right to purchase its Pro Rata Fraction, then any Offeree who so elects shall have
the right for a period of ten (10) days from the expiration of the Initial Offer Period (the “Secondary Offer Period”) to purchase, on a pro rata basis with any other Offeree who so elect, up to any Pro Rata Fraction not
purchased by an Offeree (the “Remaining Shares”). The Company shall offer to each Offeree by written notice the right to purchase the Remaining Shares and shall specify in such notice the number, price and payment terms for the
Remaining Shares. Each Offeree may accept the Company’s offer for the Remaining Shares as to the full number of securities offered to it or any lesser number, by written notice thereof given by it to the Company prior to the expiration of the
Secondary Offer Period, in which event the Company shall promptly sell and each such Offeree will buy, upon the terms specified, the number of Remaining Shares agreed to be purchased by such Offeree. 

(d) Subject to the foregoing, the Company shall be free at any time prior to one hundred eighty days (180) days after the last day of the
Secondary Offer Period, to offer and sell to any third party or parties the remainder of such securities proposed to be issued by the Company (including but not limited to the securities not agreed by the Offerees to be purchased by them), at the
price and on payment terms as those specified in such notice of offer to each Offeree; provided, however, if such third party sale or sales are not consummated within such one hundred eighty (180)-day period, the Company shall not sell
such securities as shall not have been purchased within such period without again complying with this Section 3.2.

 3.3 Reserve for Conversion Shares. The Company shall at all times reserve and keep
available out of its authorized but unissued Common Shares and Class A Fixed Value Special Shares, for the purpose of effecting the conversion of the Preferred Shares and otherwise complying with the terms of this Agreement, such number of its
duly authorized Common Shares and Class A Fixed Value Special Shares, as shall be sufficient to effect the conversion of the Preferred Shares from time to time outstanding or otherwise to comply with the terms of this Agreement. If at any time
the number of authorized but unissued Common Shares and Class A Fixed Value Special Shares, shall not be sufficient to effect the conversion of the Preferred Shares or otherwise to comply with the terms of this Agreement, the Company will
forthwith take such corporate action as may be necessary to increase its authorized but unissued Common Shares and Class A Fixed Value Special Shares, to such number of shares as shall be sufficient for such purposes. The Company will obtain
any authorization, consent, approval or other action by or make any filing with any court or administrative body that may be required under applicable securities laws in connection with the issuance of Common Shares and Class A Fixed Value
Special Shares, upon conversion of the Preferred Shares. 
 3.4 Corporate Existence. The Company shall maintain and cause each of its
Subsidiaries (other than non-operating Subsidiaries that do not hold any assets, have any liabilities or carry on any business) to maintain their respective corporate existence, rights and franchises in full force and effect. Notwithstanding the
foregoing sentence, the Company may complete any corporate reorganization if, immediately following such reorganization, there are no changes to the then shareholdings in the Company or to the rights, powers and privileges of the Preferred Shares.
Further, the Company may cause one or more of its Subsidiaries to be dissolved if the result thereof is that all of the assets and liabilities of such Subsidiary become those of the Company or of a new entity wholly-owned by the Company. 

3.5 Properties, Business, Insurance. The Company shall maintain and cause each of its Subsidiaries to maintain as to their respective
properties and business, with insurance companies reasonably believed by the Company to be financially sound and reputable insurers, insurance against such casualties and contingencies and of such types and in such amounts as is customary for
companies similarly situated, which insurance shall be deemed by the Company to be sufficient. Without limitation of the foregoing, the Company shall maintain, at the Company’s expense, insurance in an amount determined in good faith by the
Board of Directors to be appropriate, on behalf of any person who after the Closing is or was a director or officer of the Company or any Subsidiary, or is or was serving at the request of the Company or any Subsidiary as a director, officer,
employee or agent of another limited company, corporation, partnership, joint venture, trust or other enterprise, including any direct or indirect Subsidiary of the Company, against any expense, liability or loss asserted against such person and
incurred by such person in any such capacity, or arising out of such person’s status as such, subject to customary exclusions. 
 3.6
Inspection, Consultation and Advice. The Company shall permit and cause each of its Subsidiaries to permit each Investor and its representatives, at such Investor’s expense, as the case may be, to visit and inspect any of the properties
of the Company and its Subsidiaries, examine their books and take copies and extracts therefrom, discuss the affairs, finances and accounts of the Company and its Subsidiaries with their officers, employees and public accountants (and the Company
hereby authorizes said accountants to discuss with such Investor, 








  Investor Rights Agreement — Page
 19
 
  

 
as the case may be, and such designees such affairs, finances and accounts), and consult with and advise the management of the Company and its Subsidiaries as to their affairs, finances and
accounts, all at reasonable times, upon reasonable notice, and with a minimum of disruption to the subject’s business operations. Notwithstanding the foregoing, no Investor (nor its representatives) shall be entitled to inspect any documents
(nor have any discussions with respect to any documents) which, in the written opinion of counsel to the Company, are subject to attorney/client privilege as between the Company and its legal advisors. 

3.7 Restrictive Agreements Prohibited. Neither the Company nor any of its Subsidiaries shall become a party to any agreement which by
its terms restricts the Company’s performance of any of the Transaction Documents or the Articles. 
 3.8 Transactions with
Affiliates. Except for transactions contemplated by this Agreement, the other Transaction Documents or as otherwise approved by a majority of the outstanding Preferred Shares, neither the Company nor any of its Subsidiaries shall directly or
indirectly enter into any transaction with (a) any director, officer, key employee or holder of more than three percent (3%) of the outstanding capital stock of any class or series of capital stock of the Company or any of its
Subsidiaries, or (b) any person who, to the knowledge of the Company and its Subsidiaries after due inquiry, is (i) a member of the family of any person described in clause (a) or (ii) a corporation, partnership, trust or other
entity in which any person described in clause (a), or member of the family of any person described in clause (a), is a director, officer, trustee, partner or holder of more than five percent (5%) of the outstanding capital stock thereof,
except in all cases for transactions on customary terms related to such person’s employment. 
 3.9 Board of Directors Meetings.
The Company shall ensure that at least six (6) meetings of its Board of Directors are held, in person or by conference call, every fiscal year and that such meetings are held at least once per fiscal quarter in accordance with an agreed upon
schedule. 
 3.11 Compensation Committee. No compensation or other remuneration shall be paid to, and no capital stock of the Company
shall be issued to or granted to, any executive of the Company (including the Company’s Chief Executive Officer or Chairperson and any individual reporting to such persons) without the approval of the Compensation Committee or in accordance
with compensation arrangements in effect as of the date of this Agreement. No employee stock option plan, employee stock purchase plan, employee restricted stock plan or other employee stock plan (or any amendment of any of the Company’s
existing employee stock plans) shall be established or modified without the approval of the Compensation Committee. 
 3.12 Tax
Matters. 
 (a) The Company shall, and shall cause its Subsidiaries to, use their reasonable best efforts, consistent with the
Company’s business objectives to prevent the Company or any of its Subsidiaries from becoming (i) a “controlled foreign corporation” within the meaning of Section 957 of the Internal Revenue Code of 1986, as amended (the
“Code”); or (ii) a “passive foreign investment corporation” within the meaning of Section 1297 of the Code, The Company shall not be responsible for any damages arising out of a breach of the Company’s









  Investor Rights Agreement — Page
 20
 
  

 
obligations under this Section 3.12 if the Investors have approved the transactions undertaken by the Company that give rise to such breach. The parties acknowledge and agree that,
with respect to possible future acquisitions by the Company, the parties have executed other agreements in connection with this Agreement that contain specific provisions that deal with consent or veto rights that the Investors have with respect to
such acquisitions, and this Section 3.12(a) is not intended to provide any additional consent or other rights to the Investors with respect to such possible future acquisitions. For sake of clarity, if the Investors do not have consent
or veto rights with respect to a particular acquisition under those other specific provisions, this Section 3.12(a) shall not be used by the Investors to attempt to prevent the Company from proceeding with such acquisition, even if the
acquisition causes the Company to become a “controlled foreign corporation” by virtue of increasing the portion of the Company’s stock that is owned by “U.S. Shareholders” as defined in Section 951(b) of the Code. 

(b) The Company shall, and shall cause its Subsidiaries to, use their best efforts to prevent the Preferred Shares from becoming “taxable
Canadian property” under the current definition, within the meaning of the Income Tax Act (Canada) (the “Act”). The Company agrees to comply in all respects with any reporting requirements that may be imposed in connection with
the conversion of the Preferred Shares so as to assist the Investor to meet its objective, if applicable, that such conversion is effected on a tax-free basis, including without limitation, to timely execute and file a joint election under
Section 85 of the Act, if requested by the Investor, and to assist any Investor in obtaining a certificate under Section 116 of the Act. In the event that, notwithstanding the Company’s best efforts to the contrary, the Preferred
Shares become “taxable Canadian property,” at any Investor’s reasonable request, the Company will cooperate with the Investor on a reasonable basis to assist the Investor in restructuring its ownership of Preferred Shares.
Notwithstanding anything herein contained, the Company shall not be required to take any action pursuant to this paragraph that would or could reasonably be expected to cause any adverse consequence to the Company or its other shareholders. 

(c) The Company shall not withhold any tax on amounts payable or distributable to any Investor without providing such Investor with notice of
such withholding and an opportunity to obtain reduced rates of withholding or other available exemptions. Subject to applicable law, for this purpose, certifications providing the information required by applicable withholding tax provisions by the
general partner of any Investor which is a partnership shall be deemed to be acceptable to the Company for purposes of applicable withholding tax provisions and certification requirements. Subject to applicable law, if the Company reasonably
determines that withholding tax applies, the Company may withhold the required amounts from payments to an Investor, and the Company may remit such amount to the applicable taxing authority, unless, prior to the remittance thereof to the applicable
taxing authority, such Investor provides to the Company (i) evidence reasonably satisfactory to the Company that a reduced withholding tax rate applies, and (ii) an agreement to indemnify the Company in respect thereof, in form reasonably
satisfactory to the Company; in which case, the Company may withhold and remit the withholding tax calculated at the reduced withholding tax rate. 

(d) Without the consent of the Investors, the Company shall not enter into any contract involving the sale, exchange or other disposition of
shares of the Company if the holders of stock in the Company who are resident in Canada would be entitled to the benefits of 








  Investor Rights Agreement — Page
 21
 
  

 
applicable “rollover” or other nonrecognition treatment under Canadian tax law but Investors who are non-residents of Canada would be subject to taxation under Canadian or United States
tax law in connection with selling, exchanging or disposing of shares of the Company in such transaction. 
 (e) The Company shall, and
shall cause its Subsidiaries to, comply in all respects with the undertakings set forth in Schedule II and Schedule III hereto. 

(f) Upon reasonable notice of any Investor, and subject to a reasonable confidentiality undertaking by the Investor in respect of same, the
Company shall promptly provide to such Investor all tax, accounting and financial information and calculations reasonably necessary in order for such Investor to fulfill its United States federal, state and local tax reporting requirements and other
obligations in connection with owning shares in the Company and shall provide to such Investor such additional information and calculations as may be reasonably requested in order for such Investor or its direct or indirect beneficial owners to
obtain any applicable United States federal, state or local tax benefits; provided that any such additional information and calculations may be provided by the Company without undue burden or material adverse effect on the Company. 

(g) The Company and its Subsidiaries shall make such U.S. federal, state and/or local tax elections as may be reasonably requested from time
to time by the Investors, provided that such election does not adversely affect the Company, its Subsidiaries or any shareholder of the Company; provided that any de minimis or routine preparation, filing or other costs of the Company shall
not be treated as adversely affected the Company. 
 (h) Neither the Company nor any of its Subsidiaries shall make any U.S. federal, state
and/or local tax election that to the knowledge of the Company (after due inquiry, including consultation with the Company’s U.S. independent accountants), would have a material adverse effect on the Investors without having obtained the prior
consent (or direction as set forth in paragraph (g) above) of the Investors;. 
 3.13 By-Laws. The Company shall at all times
cause its By-Laws to provide that, (a) any director shall have the right to call a meeting of the Company’s Board of Directors, (b) any holder or holders of at least ten percent (10%) of the outstanding Preferred Shares or Common
Shares, shall have the right to call a meeting of the Company’s Board of Directors or stockholders, and (c) the number of directors fixed in accordance therewith shall in no event conflict with any of the terms or provisions of the
Preferred Shares as set forth in the Articles. The Company shall at all times maintain provisions in its By-Laws and Articles indemnifying all directors against liability, requiring the Company to advance directors’ expenses and absolving all
directors from liability to the Company and its stockholders to the maximum extent permitted under the Business Corporations Act (Ontario) and other applicable laws of Canada. 

3.14 Employee Contracts. The Company shall not amend, modify, terminate, waive or otherwise alter, in whole or in part, any of the
Employee Confidentiality and Assignment Agreements or Consultant Agreements (each as described in Section 3.16) without the consent of the Board of Directors.

 3.15 Vesting of Employee Shares. The Company shall not grant to any of its or any of
its Subsidiaries’ employees any options, warrants, restricted stock or other equity incentive awards, which, in all cases, will become exercisable at a rate in excess of 25% per annum from the date of such grant without the consent of at
least a majority of the outstanding Preferred Shares. The Company will require, as a condition of any grant, that such grant be pursuant to a form of option or other award agreement approved by the Company’s Board of Directors. Such agreement
shall contain provisions granting the Company a right of first refusal of transfers of Company securities by a grantee to third parties. In the event the Company issues securities to any person or entity, such person or entity shall become a party
to the Shareholders Agreement as a “Shareholder” (as such term is defined in the Shareholders Agreement substantially in the form attached as Exhibit A hereto), except such person shall not be required to become a party thereto if
the only securities held by such person consist of unexercised options unless and until such options are actually exercised. The Company shall not grant any options, warrants, restricted stock or other equity incentive awards pursuant to agreements
containing acceleration provisions without the unanimous approval of the Compensation Committee.

3.17 Activities of Subsidiaries. Unless approved by a majority of the outstanding Preferred Shares, the Company will not organize or
acquire any entity that is a Subsidiary unless such Subsidiary is wholly-owned (directly or indirectly) by the Company. Unless approved by a majority of the outstanding Preferred Shares, the Company shall not sell or otherwise transfer any shares of
capital stock of any Subsidiary, except to the Company or another Subsidiary, or permit any Subsidiary to issue, sell or otherwise transfer any shares of its capital stock or the capital stock of any Subsidiary, except to the Company or another
Subsidiary. Unless approved by a majority of the outstanding Preferred Shares, the Company shall not permit any Subsidiary to purchase or set aside any sums for the purchase of, or pay any dividend or make any distribution on, any shares of its

when the Board of Directors of the Company (including the approval of the Preferred Director) determine to use different accounting principles (including, without limitation, United States generally accepted accounting principles or international
financial reporting standards) in connection with the preparation of the Company’s financial statements and the keeping of its books of accounts. 

3.20 Change in Nature of Business. Unless approved by a majority of the outstanding Preferred Shares, the Company shall not make, or
permit any Subsidiary to make, any material change in the nature of its business as conducted on the date hereof. 
 3.21 Rule 144A
Information. The Company shall, at all times during which it is neither subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act; nor exempt from reporting pursuant to Rule 12g3-2(b) under the Exchange Act,
provide in writing, upon the written request of any Investor or a prospective buyer of Preferred Shares or Conversion Shares from any Investor, all information required by Rule 144A(d)(4)(i) of the General Regulations promulgated by the
Commission under the Securities Act (“Rule 144A Information”). 
 3.22 Acquisitions/Investments. The Company

  Investor Rights Agreement — Page

purchase such holder’s Preferred Shares pursuant to this Section 3.23 and the Company fails to do so, the Company shall indemnify such Investor and hold such Investor harmless
from and against any resulting tax liability. Notwithstanding anything herein contained, nothing in this Section 3.23 shall oblige the Company, its Subsidiaries, or affiliated entities to take any action pursuant to this
Section 3.23, if such action is prohibited by law, or if such action would or could reasonably be expected to cause adverse consequence to the Company, its subsidiaries, affiliated entities, or the other shareholders. All expenses
related to any such accommodation by the Company, its Subsidiaries and/or related entitles shall be paid by the holders of the Preferred Shares. 

3.24 Transactions with Careworx. For so long as any Affiliate of the Company beneficially owns, directly or indirectly, any securities

its Subsidiaries to their respective customers in the ordinary course of business and (ii) maintain commercial relationships with each such referred customer on terms and conditions that are no less favorable to the Company and its Subsidiaries
as the terms and conditions in effect for customers of similar size and receiving similar services from the Company and/or its Subsidiaries and that the Company has not referred or otherwise directed to Careworx. The Company and the Investors agree
and acknowledge that, in the event that the Company acquires Resource Systems, Inc., the Investors and the Company will negotiate in good faith to structure such acquisitions so as to avoid any conflict of interest between the Company and the
shareholders of the Company who also have an ownership interest in Careworx that is fair and equitable to the Company.

 SCHEDULE I 

INVESTORS 
 JMI Equity Fund VII, L.P. 







 SCHEDULE II 

The Company and its Subsidiaries shall comply with the undertakings set forth below for each year (or portion thereof) in which the Company or
any of its Subsidiaries is a “controlled foreign corporation” within the meaning of Section 957 of the Internal Revenue Code of 1986, as amended (the “Code”). The Company or any of its Subsidiaries, as applicable,
shall retain such independent advisors as may be necessary to assist with the following undertakings and will bear the expenses associated with such independent advisors. 
  

	1.	Within 30 business days following March 31, June 30, September 30 and December 31 of each year (each, a “Calendar Quarter”), the Company shall determine the current and
accumulated “earnings and profits” of the Company and each of its Subsidiaries, calculated in accordance with Section 964 of the Code, and provide such information to any Investor that is a “United States person” as defined
in Section 7701(a)(30) the Code (a “U.S. Investor”). 

  

	2.	The Company agrees that it and each of its Subsidiaries will use commercially reasonable efforts, consistent with the Company’s business objectives, to avoid (a) realizing “subpart F income,” as
defined in Section 952 of the Code, and (b) causing the Investors to include amounts in gross income pursuant to Sections 951(a)(1)(B) and 956 (“Investment of earnings in United States property”) of the Code. 


 

	3.	The Company shall review the financial position of the Company and each of its Subsidiaries each Calendar Quarter to determine the amount, if any, of its subpart F income and earnings invested in U.S. property. If,
notwithstanding the undertakings in paragraph 2 above, the Company determines that it is likely that in any Calendar Quarter the Company has realized or will realize subpart F income or has increased or will increase its earnings invested in U.S.
property, the Company shall immediately so inform the U.S. Investors and consider what steps, if any, should be taken by the Company to reduce the amount of its subpart F income or earnings invested in U.S. property, as the case may be, for the
current quarter and for future periods. 








 SCHEDULE III 

The Company and its Subsidiaries shall follow the guidelines set forth below in order to determine whether it is properly classified as a
passive foreign investment company (a “PFIC”) as defined in Section 1297 of the United States Internal Revenue Code of 1986, as amended (the “Code”). 

The Company or any of its non-U.S. Subsidiaries will be a PFIC for any taxable year in which either (i) 75% or more of its gross income
is “passive income” within the meaning of Section 1297(b) of the Code or (ii) on average for the taxable year, 50% or more of its assets (by value), produce or are held for the production of passive income (“passive
assets”). Assets which do not produce passive income are hereinafter referred to as “nonpassive assets”. 
  

	1.	Within 30 business days following the end of each of the first three quarters of each taxable year of the Company and its Subsidiaries, the principal financial or accounting officer of the Company (the
“CFO”) will review the financial position of the Company and its Subsidiaries to determine the extent of their passive and nonpassive income for the quarter. For purposes of this determination, the CFO will apply the guidelines
contained in IRS Notice 88-22, 1988-1 CB 489, or such other applicable regulatory or administrative pronouncements as may have been issued by the Internal Revenue Service or such judicial interpretations as may have been rendered prior to the date
of such review. 

  

	2.	If, based upon such review, the CFO determines that it is likely that, as of the end of such quarter, the Company or any of its Subsidiaries may have had passive income which exceeds 70% of its total gross income or
passive assets which exceed 45% of its total assets, then the CFO will immediately so inform the Investors and consider what steps, if any, should be taken by the Company or its Subsidiaries to reduce the amount of passive income and/or the amount
of passive assets, as the case may be, for future periods. 

  

	3.	Promptly following the end of each taxable year, the CFO will again review the financial position of the Company and its Subsidiaries and make a final determination of the extent of their passive and nonpassive income
for such taxable year and their passive and nonpassive assets as of the end of such taxable year, applying the same guidelines as are referenced in paragraph 1 above. In the event that the CFO determines that the Company may have had passive income
which exceeds 70% of its total gross income or passive assets which exceed 45% of its total assets, then the CFO will immediately so inform the Investors and consider what steps, if any, should be taken by the Company or its Subsidiaries to reduce
the amount of passive income and/or the amount of passive assets, as the case may be, during the next following taxable year. 

  

	4.	If, despite the Company’s best efforts, the Company would be treated as a PFIC, the Company shall comply with the information and other reporting requirements set forth in Subtitle A, Chapter 1, Subchapter P, Part
VI of the Code. 

  

	5.	 If, despite the Company’s and its Subsidiaries’ best efforts, the Company or any of its Subsidiaries would be treated as a PFIC, the Company
or its Subsidiaries, as applicable, 










	 	
shall, for the year of such determination and each subsequent year, timely provide each of the Investors with a properly completed and duly executed “PFIC Annual Information Statement”
that meets the requirements of U.S. Treasury Regulations Section 1.1295-1(g) and any other information or assistance required by such regulations or otherwise necessary for the Investors or their direct or indirect owners to (i) make a
timely election to treat such entity that is a PFIC as a “qualified electing fund” under Section 1295 of the Code and (ii) timely fulfill their annual election requirements (as described in U.S. Treasury Regulations
Section 1.1295-1(f)) in each subsequent year in which any of the Investors owns an interest (directly or indirectly) in such entity. Each PFIC Annual Information Statement provided to the Investors pursuant to the preceding sentence shall be
prepared by a qualified U.S. tax advisor experienced in such matters. Furthermore, if the Company or any of its Subsidiaries is a PFIC, such entity shall use reasonable best efforts, consistent with the Company’s or its Subsidiaries’
business objectives, as applicable, not to generate any income, gains or other earnings and profits, as determined for U.S. federal income tax purposes, from transactions entered into outside of the ordinary course of its business during any period
in which any of the Investors holds an interest (directly or indirectly) in such entity. For purposes of the previous sentence, transactions entered into outside of the ordinary course of business shall include, but shall not be limited to,
transfers of assets between and among the Company and its Subsidiaries and transfers of the Company or its Subsidiaries or interests in such entities.

Company shall communicate in writing its election to purchase to the transferring Shareholder and each other Security Holder, which communication shall state the number of Shareholder Offered Shares the Company desires to purchase and shall be
delivered in person or mailed to the transferring Shareholder and each other Security Holder within twenty (20) days of the date of the Shareholder Offer. Subject to Section 3.2(g) below, such communication shall, when taken in
conjunction with the Shareholder Offer, be deemed to constitute a valid, binding and enforceable agreement for the sale and purchase of the Shareholder Offered Shares. 

(c) Security Holder’s Right of First Refusal. If, within twenty (20) days of its receipt of the Shareholder Offer, the
Company fails to deliver written notice to the transferring Shareholder and each other Security Holder of its intention to purchase all of the Shareholder Offered Shares (the Shareholder Offered Shares which the Company does not elect to purchase









 Shareholders Agreement – Page 6 

 

 
being referred to as the “Shareholder Refused Shares”), then, subject to Section 3.2(g) below, each other Security Holder shall have the right to purchase up to that
number of Shareholder Refused Shares as shall be equal to the number of Shareholder Refused Shares multiplied by a fraction, the numerator of which shall be the number of Common Shares (calculated on an as-converted basis) then owned by such
Security Holder, and the denominator of which shall be the aggregate number of Common Shares (calculated on an as-converted basis) then owned by all Security Holders. The amount of Shareholder Refused Shares that each other Security Holder is
entitled to purchase under this Section 3.2 shall be referred to as its “Shareholder Pro Rata Fraction.” 
 (d)
Oversubscription Rights. The Security Holders shall have a right of oversubscription such that if any Security Holder declines to purchase its Shareholder Pro Rata Fraction, the other Security Holders shall, among them, subject to
Section 3.2(g) below, have the right to purchase up to the balance of the Shareholder Refused Shares not so purchased. Such right of oversubscription may be exercised by a Security Holder by accepting the offer of the Shareholder Refused
Shares as to more than its Shareholder Pro Rata Fraction in accordance with Section 3.2(e) below. If, as a result thereof, such oversubscriptions exceed the total number of Shareholder Refused Shares available in respect of such
oversubscription privilege, the oversubscribing Security Holders shall be reduced with respect to their oversubscriptions on a pro rata basis in accordance with their respective Shareholder Pro Rata Fractions or as they may otherwise agree among
themselves. 
 (e) Security Holder Notice of Intent to Purchase. If a Security Holder desires to purchase all or any part of the
Shareholder Refused Shares, such Security Holder shall communicate in writing its election to purchase to the transferring Shareholder, which communication shall state the number of Shareholder Refused Shares the Security Holder desires to purchase
and shall be delivered in person or mailed to the transferring Shareholder within forty (40) days of the date of the Shareholder Offer. Subject to Section 3.2(g) below, such communication shall, when taken in conjunction with the
Shareholder Offer, be deemed to constitute a valid, binding and enforceable agreement for the sale and purchase of such Shareholder Refused Shares (subject to the aforesaid limitations as to a Security Holder’s right to purchase more than such
Security Holder’s Shareholder Pro Rata Fraction). 
 (f) Closing. Sales of the Shareholder Offered Shares to be sold to the
Company or Shareholder Refused Shares to be sold to the participating Security Holders pursuant to this Section 3.2 shall be made at the offices of the Company within sixty (60) days after the date of the Shareholder Offer. Such
sales shall be effected by the transferring Shareholder’s delivery to the Company or participating Security Holders(s) of a certificate or certificates evidencing the Shareholder Offered Shares or Shareholder Refused Shares, as the case may be,
to be purchased by it, duly endorsed for transfer to the Company or participating Security Holder(s), as the case may be, against payment to the transferring Shareholder of the purchase price therefor by the Company or said participating Security
Holder(s), as the case may be. 
 (g) Sale to Third Party. If all of the Shareholder Offered Shares are not purchased by the Company
and the other Security Holders, collectively, within the time frame 








 Shareholders Agreement – Page 7 

 

 
specified in this Section 3.2, all of the Shareholder Offered Shares may be sold by the transferring Shareholder to the Proposed Transferee at any time within ninety (90) days
after the date the Shareholder Offer was made to the Company and the other Security Holders, subject to full compliance with the other provisions of this Article III. Any such sale shall be to the Proposed Transferee, at the price and upon
other terms and conditions, if any, as those specified in the Shareholder Offer. Any Shareholder Offered Shares not sold within such ninety (90)-day period shall continue to be subject to the requirements of a prior offer pursuant to this
Section 3.2. If Shareholder Refused Shares are sold pursuant to this Section 3.2 to an Investor or affiliate thereof, in such case only, the Shareholder Refused Shares so sold to such Investor shall only be subject to the
restrictions imposed by this Agreement to the extent that other Shares owned by such Investor are subject to the restrictions imposed by this Agreement. 

(h) Certain Sales Excluded. The Company’s and Security Holders’ right of refusal provided in this Section 3.2
shall not apply with respect to (i) sales of Shares to the Company, (ii) sales by a Founder pursuant to his co-sale rights under Section 3.5 below or (iii) sales of Shares in a Sale Event. 

3.3 Right of First Offer on Dispositions of Investor’s Shares. 

(a) Offer by an Investor. If at any time any Investor desires to Transfer all or any portion of such Investor’s Shares, such
transferring Investor shall submit a written offer (the “Investor Offer”) to sell such Shares (the “Investor Offered Shares”) to the Company and Michael Wessinger and David Wessinger (collectively the
“Founders” or individually a “Founder”) pursuant to the terms and conditions set forth in this Section 3.3. For the purposes of this Article III, the term “Founders” shall be deemed to
include any Affiliates of a Founder (which, for the avoidance of doubt, shall include any trust in which the trustees consist solely of Founders or the beneficiaries of such trust include only the Founders, their immediate family members or a
corporation controlled by any of the foregoing) and each Founder shall have the discretion to allocate any Investor Offered Shares acquired pursuant to this Section 3.3 amongst such Affiliates. The Investor Offer shall disclose the
number and type of Investor Offered Shares proposed to be sold and the terms and conditions (including price) of the proposed sale. The Investor Offer shall further state that the Company and the Founders may acquire, in accordance with the
provisions of this Agreement, all but not less than all of the Investor Offered Shares for the price and upon the other terms and conditions set forth therein. The Investors, in the aggregate, may not submit more than two (2) Investor Offers in
any twelve (12) month period. 
 (b) Company Notice of Intent to Purchase. If the Company desires to purchase all or any part of
the Investor Offered Shares, the Company shall communicate in writing its election to purchase to the transferring Investor and each of the Founders, which communication shall state the number of Investor Offered Shares the Company desires to
purchase and shall be delivered in person or mailed to the transferring Investor and each of the Founders within twenty (20) days of the date of the Investor Offer. Subject to Section 3.3(g) below, such communication shall, when
taken in conjunction with the Investor Offer, be deemed to constitute a valid, binding and enforceable agreement for the sale and purchase of the Investor Offered Shares. 








 Shareholders Agreement – Page 8 

 

 (c) Founders’ Secondary Right of First Offer. If, within twenty (20) days of
its receipt of the Investor Offer, the Company fails to deliver written notice to the transferring Investor and each of the Founders of its intention to purchase all of the Investor Offered Shares (the Investor Offered Shares which the Company does
not elect to purchase being referred to as the “Investor Refused Shares”), each of the Founders shall have, subject to Section 3.3(g) below, the right to purchase that number of Investor Refused Shares as shall be equal
to the number of Investor Refused Shares multiplied by a fraction, the numerator of which shall be the number of Common Shares (calculated on an as-converted basis) then owned by such Founder, and the denominator of which shall be the aggregate
number of Common Shares (calculated on an as-converted basis) then owned by all of the Founders. The amount of Investor Refused Shares that each of the Founders is entitled to purchase under this Section 3.3 shall be referred to as its
“Investor Pro Rata Fraction.” 
 (d) Oversubscription Rights. The Founders shall have a right of
oversubscription such that if any Founder declines to purchase its Investor Pro Rata Fraction, the other Founder shall have the right, subject to Section 3.3(g) below, to purchase up to the balance of the Investor Refused Shares not so
purchased. Such right of oversubscription may be exercised by a Founder by accepting the offer of the Investor Refused Shares as to more than its Investor Pro Rata Fraction in accordance with Section 3.3(e) below. 

(e) Security Holder Notice of Intent to Purchase. If a Founder desires to purchase all or any part of the Investor Refused Shares, such
Founder shall communicate in writing its election to purchase to the transferring Investor, which communication shall state the number of Investor Refused Shares the Founder desires to purchase and shall be delivered in person or mailed to the
transferring Investor within forty (40) days of the date of the Investor Offer. Subject to Section 3.3(g) below, such communication shall, when taken in conjunction with the Investor Offer, be deemed to constitute a valid, binding
and enforceable agreement for the sale and purchase of such Investor Refused Shares (subject to the aforesaid limitations as to a Founder’s right to purchase more than such Founder’s Investor Pro Rata Fraction). 

(f) Closing. Sales of the Investor Offered Shares to be sold to the Company or Investor Refused Shares to be sold to the participating
Founders pursuant to this Section 3.3 shall be made at the offices of the Company within sixty (60) days after the date of the Investor Offer. Such sales shall be effected by the transferring Investor’s delivery to the Company
or participating Founder(s) of a certificate or certificates evidencing the Investor Offered Shares or Investor Refused Shares, as the case may be, to be purchased by it, duly endorsed for transfer to the Company or participating Founder(s), as the
case may be, against payment to the transferring Investor of the purchase price therefor by the Company or said participating Founder(s), as the case may be. 

(g) Sale to Third Party. If all of the Investor Offered Shares are not purchased by the Company and the Founders, collectively, within
the time frame specified in this Section 3.3, all of the Investor Offered Shares may be sold by the transferring Investor at any time within one hundred twenty (120) days after the date the Investor Offer was made to the Company and
the Founders, subject to full compliance with the other provisions of this Article III. Any such sale shall be at a price not less than the price stated in the Investor Offer and shall be upon other









 Shareholders Agreement – Page 9 

 

 
terms and conditions, if any, not materially more favorable to the buyer(s), in the aggregate, as those specified in the Investor Offer. Any Investor Offered Shares not sold within such one
hundred twenty (120) day period shall continue to be subject to the requirements of a prior offer pursuant to this Section 3.3. 

(h) Certain Sales Excluded. The Company’s and Founders’ right of offer provided in this Section 3.3 shall not
apply with respect to (i) sales of Shares to the Company, (ii) sales of Shares by an Investor pursuant to its co-sale rights under Section 3.4 below or (iii) sales of Shares in a Sale Event. 

3.4 Right of Participation in Sales by Shareholders. 

(a) Co-Sale Right of Investors. Subject to Section 3.2 above, if at any time a Shareholder proposes to Transfer any Shares
(the “Co-Sale Shares”) to a Proposed Transferee other than the Company (a “Buyer”), each of the Investors shall have the right to sell to such Buyer, as a condition to such sale by such Shareholder, at the same
price per share and on the same terms and conditions as involved in such sale by such Shareholder (as stated in the Shareholder Offer provided under Section 3.2(a)), such number of shares equal to the Co-Sale Shares multiplied by a
fraction, the numerator of which is the aggregate number of Common Shares (calculated on an as-converted basis) owned by the particular Investor desiring to sell Shares to such Buyer, and the denominator of which is the sum of all Common Shares
(calculated on an as-converted basis) owned by all Investors desiring to participate in a sale to such Buyer under this Section 3.4 plus all Common Shares (calculated on an as-converted basis) owned by such Shareholder. 

(b) Notice of Intent to Participate. Each Investor wishing to participate in any Transfer under this Section 3.4 shall
notify in writing the Shareholder transferring hereunder of such intention as soon as practicable after such Investor’s receipt of the Shareholder Offer made pursuant to Section 3.2(a), and in any event within sixty (60) days
after the date such Shareholder Offer was made. 
 (c) Sale to a Proposed Transferee. The Shareholder selling hereunder and each
participating Investor shall sell to the Buyer all, or at the option of the Buyer, any part of the shares proposed to be sold by them at the price and upon such other terms and conditions, if any, as those in the Shareholder Offer provided by such
Shareholder under Section 3.2(a); provided, however, that any purchase of less than all of such shares by the Buyer shall be deducted from the number of shares offered to be sold by such Shareholder and each participating
Investor pro rata based upon the applicable number of Co-Sale Shares desired to be sold by the Shareholder and the number of shares that each participating Investor is entitled to sell pursuant to Section 3.4(a). 

(d) Prohibited Transfers. In the event of any Transfer of any shares or other securities of the Company by a Shareholder in violation
of any provision of Section 3.4, each Investor shall have the right to elect to cause such Shareholder to purchase, and such Shareholder shall be obligated to purchase, from such Investor, at the same price per share and on the same
terms and conditions as involved in such sale by the Shareholder, such number of Shares 








 Shareholders Agreement – Page 10 

 

 
(calculated on an as-converted basis) equal to the number of Shares sold by such Shareholder multiplied by a fraction, the numerator of which is the aggregate number of Common Shares owned by any
particular Investor desiring to sell Shares to such Shareholder under this Section 3.4 (calculated on an as-converted basis) and the denominator of which is the sum of all Common Shares owned by all Investors desiring to sell Shares to
such Shareholder under this Section 3.4 (calculated on an as-converted basis) plus the number of Common Shares (calculated on an as-converted basis) owned by such Shareholder immediately prior to such Transfer. 

3.5 Right of Participation in Sales by Investors. 

(a) Co-Sale Right of Founders. Subject to Section 3.3 above, if at any time an
Investor proposes to Transfer any Shares (“Investor Co-Sale Shares”) to a Buyer, such Investor shall, in each case, submit a written notice, which shall set forth the number and type of
Investor Co-Sales Shares proposed to be sold to such Buyer and the terms and conditions (including price) of the proposed sale (the “Co-Sale Notice”), to each of the Founders, which shall have
the right to sell to such Buyer, as a condition to such sale by such Investor, at the same price per share and on the same terms and conditions as set forth in the Co-Sale Notice, such number of shares equal to the Investor Co-Sale Shares multiplied
by a fraction, the numerator of which is the aggregate number of Shares (calculated on an as-converted basis) owned by the respective Founder desiring to sell Shares to such Buyer, and the denominator of which is the sum of all Shares (calculated on
an as-converted basis) owned by all Founders desiring to participate in a sale to such Buyer under this Section 3.5 plus the number of Common Shares (calculated on an as-converted basis) owned by such Investor. 

(b) Notice of Intent to Participate. Each Founder wishing to participate in any Transfer under this Section 3.5 shall
notify in writing the Investor transferring hereunder of such intention as soon as practicable after such Founder’s receipt of the Co-Sale Notice and in any event within twenty (20) days of such receipt. 

(c) Sale to a Proposed Transferee. The Investor selling hereunder and each participating Founder shall sell to the Buyer all, or at the
option of the Buyer, any part of the Shares proposed to be sold by them at the price and upon such other terms and conditions, if any, as those in the Co-Sale Notice; provided, however, that any purchase of less than all of such shares
by the Buyer shall be deducted from the number of Shares offered to be sold by such Investor and each participating Founder pro rata based upon the applicable number of Investor Co-Sale Shares desired to be sold by the Founder and the number of
shares that each participating Founder is entitled to sell pursuant to Section 3.5(a). 
 (d) Prohibited Transfers. In
the event of any Transfer of any shares or other securities of the Company by an Investor in violation of any provision of Section 3.5, each Founder shall have the right to elect to cause such Investor to purchase, and such Investor
shall be obligated to purchase, from such Founder, at the same price per share and on the same terms and conditions as involved in such sale by the Investor, such number of Shares (calculated on an as-converted to basis) equal to the number of
Shares sold by such Investor multiplied by a fraction, the numerator of which is the aggregate number of Shares owned by any particular Founder desiring to sell Shares to such Investor under this Section 3.5 (calculated on an
as-








 Shareholders Agreement – Page 11 

 

 
converted basis) and the denominator of which is the sum of all Shares owned by all Founders desiring to sell shares to such Investor under this Section 3.5 (calculated on an
as-converted basis) plus the number of Common Shares (calculated on an as-converted basis) owned by such Investor immediately prior to such Transfer. 

3.6 Instrument of Adherence. Except as otherwise provided herein, no Security Holder shall Transfer any Shares to any Person not
otherwise a party hereto who does not first execute the Instrument of Adherence substantially in the form attached hereto as Annex I (an “Instrument of Adherence”) as a “Shareholder” (if such transferring
Security Holder is a Shareholder) or “Investor” (if such transferring Security Holder is an Investor); provided that, if such Person is a Buyer pursuant to Section 3.4 or 3.5, such Person shall be a “Shareholder” or
“Investor,” respectively. If any Transfer of Shares is attempted contrary to the provisions of this Agreement, the Company shall have the right to: (i) purchase such Shares from the transferring Security Holder or the purported
transferee; (ii) obtain a temporary and/or permanent injunction restraining such Transfer (no bond or other security shall be required in connection with such action); or (iii) refuse to recognize any purported transferee as a Security
Holder and may continue to treat the transferor as a Security Holder for all purposes, including, without limitation, for purposes of dividend and voting rights, until all applicable provisions of this Agreement have been complied with. The remedies
provided herein are cumulative and not exclusive of any other remedies provided by law. 
 3.7 Prohibition on Transfers of Shares to
Competitors. No Security Holder may at any time transfer any Shares to any person or entity that engages in any business activity that is in competition, directly or indirectly, with the products or services being developed, offered, marketed,
sold or licensed by the Company. The determination of whether any proposed transferee engages in any business activity that is in competition with those of the Company shall be made by the Board in good faith. This prohibition shall be applicable in
addition to and separately from the other provisions hereof. 
 3.8 Drag-Along Rights. 

(a) If at any time (i) the holders of a majority of the issued and outstanding Class A Preferred Shares and (ii) the holders of
a majority of the issued and outstanding Common Shares (together with the holders described in immediately preceding clause (i), the “Initiating Holders”), propose to effect (or to cause the Company to effect) a Sale Event, the
Initiating Holders may deliver a notice (a “Sale Event Notice”) to all of the other Security Holders stating that the Initiating Holders propose to effect (or to cause the Company to effect) such transaction (the “Sale
Event Notice Transaction”), and specifying the name and address of the proposed parties to such transaction and the consideration payable in connection therewith. Upon receipt of a Sale Event Notice, each Security Holder shall be obligated
to Transfer all Shares owned by it in such Sale Event (or, in the case of such a Sale Event involving a sale of less than all of the outstanding Shares, a percentage of the Shares owned by it equal to the percentage of the Initiating Holders’
Shares being sold by the Initiating Holders), for a price and, subject to Section 3.8(c) below, on other terms and conditions not less favorable to the Security Holder than to the Initiating Holders; provided, however, that
the price may be different for each of the Company’s classes of stock to the extent that such difference is consistent with the liquidation 








 Shareholders Agreement – Page 12 

 

 
preferences of such classes of stock set forth in the Articles; provided further, however, that, with respect to any Shares for which a Security Holder holds unexercised stock
options or other convertible security with an associated exercise price, the price per such Share shall be reduced by the exercise price of such security or, if required pursuant to the terms of such security, such Security Holder shall pay the
exercise price therefor prior to the closing of the Sale Event Notice Transaction, and shall transfer Common Shares in the Sale Event Notice Transaction; provided further, however, that no Security Holder shall be entitled to
participate in any rollover or re-investment arrangement in connection with such Sale Event. In addition to selling its Shares, each Security Holder shall take all other necessary action to cause the Company
to consummate the proposed Sale Event, including, to the extent necessary, voting all such Security Holder’s Shares in favor of such transaction. 

(b) The closing of any Sale Event for which the Initiating Holders have delivered a Sale Event Notice pursuant to this Section 3.8
shall be held at such time and place as the Initiating Holders shall reasonably specify. At such closing, the Security Holders shall deliver certificates representing the Shares to be sold, duly endorsed for transfer and accompanied by all requisite
stock transfer taxes, if any, and the Shares to be transferred shall be free and clear of any liens, claims or encumbrances (other than restrictions imposed by this Agreement) and each of the Security Holders shall so represent and warrant. Each of
the Security Holders shall further represent and warrant that it is the record and beneficial owner of such Shares free and clear of all liens, charges, security interests, encumbrances or other rights of third parties and join in such additional
representations, warranties and related indemnities and other obligations relating to its ownership of the Shares as shall be customary in transactions of a similar nature (including without limitation any withholding obligations and escrow
arrangements). 
 (c) Notwithstanding anything herein to the contrary, in the event that the consideration to be paid in exchange for the
Shares pursuant to this Section 3.8 includes any securities and due receipt thereof by any Security Holder would require under applicable law (i) the registration or qualification of such securities or of any person as a broker or
dealer or agent with respect to such securities or (ii) the provision to any Security Holder of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited
investors” as defined in Regulation D promulgated under the United States Securities Act of 1933, as amended (the “Securities Act”), the other Security Holders may cause to be paid to such Security Holder in lieu thereof,
against surrender of the Shares which would have otherwise been sold by such Security Holder, an amount in cash equal to the fair value (as determined in good faith by the Initiating Holders) of the securities which such Security Holder would
otherwise receive as of the date of the issuance of such securities in exchange for the Shares. 
 (d) Each Security Holder, whether in its
capacity as an Initiating Holder, Security Holder, officer or director of the Company, or otherwise, shall to the fullest extent permitted by law take or cause to be taken all such actions as may reasonably be requested by the Initiating Holders in
order expeditiously to consummate each Sale Event and any related transactions, including, without limitation, executing, acknowledging and delivering consents, assignments, waivers and other documents or instruments, furnishing information and
copies of 








 Shareholders Agreement – Page 13 

 

 
documents, filing applications, reports, returns, filings and other documents or instruments with governmental authorities, and otherwise cooperating with the Company and the Initiating Holders.
Without limiting the generality of the foregoing, each Security Holder shall execute and deliver such agreements and instruments as may be reasonably specified by the Initiating Holders. 

(e) Each Security Holder hereby grants to the Initiating Holders (i) an irrevocable proxy, coupled with an interest, to vote all Shares
owned by such Security Holder, and (ii) an irrevocable power of attorney, which is coupled with an interest, to take such other actions, in each case to the extent necessary to carry out the provisions of this Section 3.8 in the
event of any breach by such Security Holder of its obligations hereunder. 
 (f) Notwithstanding any provision of this Agreement, the
purchase and sale of Shares pursuant to this Section 3.8 shall not be subject to the provisions of Sections 3.2, 3.3, 3.4, 3.5, 3.6 and 3.7 hereof. 

3.9 Drag-Along Rights By Shareholders. 

(a) If at any time the holders of a majority of the issued and outstanding Common Shares, voting together as a class (the “Shareholder
Initiating Holders”), propose to effect (or to cause the Company to effect) a Sale Event, the Shareholder Initiating Holders may deliver a notice (a “Shareholder Sale Event Notice”) to all of the other Security Holders
stating that the Shareholder Initiating Holders propose to effect (or to cause the Company to effect) such transaction (the “Shareholder Sale Event Notice Transaction”), and specifying the name and address of the proposed parties to
such transaction and the consideration payable in connection therewith. Upon receipt of a Shareholder Sale Event Notice, each Security Holder shall be obligated to Transfer all Shares owned by it in such Sale Event (or, in the case of such a Sale
Event involving a sale of less than all of the outstanding Shares, a percentage of the Shares owned by it equal to the percentage of the Shareholder Initiating Holders’ Shares being sold by the Shareholder Initiating Holders), for a price and,
subject to Section 3.9(c) below, on other terms and conditions not less favorable to the Security Holder than to the Shareholder Initiating Holders; provided, however, that the price may be different for each of the
Company’s classes of stock to the extent that such difference is consistent with the liquidation preferences of such classes of stock set forth in the Articles; provided further, however, that, with respect to any Shares for which
a Security Holder holds unexercised stock options or other convertible security with an associated exercise price, the price per such Share shall be reduced by the exercise price of such security or, if required pursuant to the terms of such
security, such Security Holder shall pay the exercise price therefor prior to the closing of the Shareholder Sale Event Notice Transaction, and shall transfer the Shares held by such Security Holder in the Shareholder Sale Event Notice Transaction;
provided further, however, that no Security Holder shall be entitled to participate in any rollover or re-investment arrangement in connection with such Sale Event. In addition to selling its
Shares, each Security Holder shall take all other necessary action to cause the Company to consummate such Sale Event, including, to the extent necessary, voting all such Security Holder’s Shares in favor of such transaction. 








 Shareholders Agreement – Page 14 

 

 (b) Notwithstanding anything herein to the contrary, the provisions of this
Section 3.9 shall not apply to the Investors and no Investor shall be compelled or otherwise required to participate in any such Sale Event, unless the sum of (i) the aggregate value of all cash payments received by the Investors
prior to the date of such Sale Event that are directly in respect of Shares owned by the Investors (exclusive of any indebtedness, management fees, consulting fees or expense reimbursements) and (ii) the aggregate cash proceeds received by the
Investors as a result of their ownership of Shares at the closing of such Sale Event (exclusive of any proceeds in escrow or earn-out or other post-closing or conditional payments to such holders) is equal to or greater than three (3) times the
aggregate purchase price for Shares held by the Investors or their Affiliates, determined as of immediately prior to such Sale Event. For the avoidance of doubt, such aggregate amount invested by the Investors as of the date hereof is
CAD$50,000,000. 
 (c) The closing of any such Sale Event for which the Shareholder Initiating Holders have delivered a Shareholder Sale
Event Notice pursuant to this Section 3.9 shall be held at such time and place as the Shareholder Initiating Holders shall reasonably specify. At such closing, the Security Holders shall deliver certificates representing the Shares to be
sold, duly endorsed for transfer and accompanied by all requisite stock transfer taxes, if any, and the Shares to be transferred shall be free and clear of any liens, claims or encumbrances (other than restrictions imposed by this Agreement) and
each of the Security Holders shall so represent and warrant. Each of the Security Holders shall further represent and warrant that it is the record and beneficial owner of such Shares free and clear of all liens, charges, security interests,
encumbrances or other rights of third parties and join in such additional representations, warranties and related indemnities and other obligations relating to its ownership of the Shares as shall be customary in transactions of a similar nature
(including without limitation any withholding obligations and escrow arrangements). 
 (d) Notwithstanding anything herein to the contrary,
in the event that the consideration to be paid in exchange for the Shares pursuant to this Section 3.9 includes any securities and due receipt thereof by any Security Holder would require under applicable law (i) the registration or
qualification of such securities or of any person as a broker or dealer or agent with respect to such securities or (ii) the provision to any Security Holder of any information other than such information as a prudent issuer would generally
furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act, the other Security Holders may cause to be paid to such Security Holder in lieu thereof, against surrender of the
Shares which would have otherwise been sold by such Security Holder, an amount in cash equal to the fair value (as determined in good faith by the Shareholder Initiating Holders) of the securities which such Security Holder would otherwise receive
as of the date of the issuance of such securities in exchange for the Shares. 
 (e) Each Security Holder, whether in its capacity as an
Shareholder Initiating Holder, Security Holder, officer or director of the Company, or otherwise, shall to the fullest extent permitted by law take or cause to be taken all such actions as may reasonably be requested by the Shareholder Initiating
Holders in order expeditiously to consummate each such Sale Event and any related transactions, including, without limitation, executing, acknowledging and delivering consents, assignments, waivers and other documents or instruments, furnishing









 Shareholders Agreement – Page 15 

 

 
information and copies of documents, filing applications, reports, returns, filings and other documents or instruments with governmental authorities, and otherwise cooperating with the Company
and the Shareholder Initiating Holders. Without limiting the generality of the foregoing, each Security Holder shall execute and deliver such agreements and instruments as may be reasonably specified by the Shareholder Initiating Holders. 

(f) Each Security Holder hereby grants to the Shareholder Initiating Holders (i) an irrevocable proxy, coupled with an interest, to vote
all Shares owned by such Security Holder, and (ii) an irrevocable power of attorney, which is coupled with an interest, to take such other actions, in each case to the extent necessary to carry out the provisions of this Section 3.9
in the event of any breach by such Security Holder of its obligations hereunder. 
 (g) Notwithstanding any provision of this Agreement, the
purchase and sale of Shares pursuant to this Section 3.9 shall not be subject to the provisions of Sections 3.2, 3.3, 3.4, 3.5, 3.6 and 3.7 hereof. 

3.10 Failure to Deliver Shares. If any Security Holder (or such Security Holder’s legal representative) who has become obligated
to sell Shares hereunder shall fail to deliver such Shares to the Company in accordance with the terms of this Agreement, the Company may, at its option, in addition to all other remedies it may have, send to such Security Holder by registered mail,
return receipt requested, the purchase price for such Shares as is herein specified. Thereupon, the Company: (i) shall cancel on its books the certificate or certificates representing such Shares to be sold; and (ii) shall issue, in lieu
thereof, a new certificate or certificates in the name of the Company representing such Shares, and thereupon all of such Security Holder’s rights in and to such Shares shall terminate. 

3.11 Market Stand-Off. Each Security Holder hereby agrees that it will not, without the prior written consent of the managing
underwriter, during the period commencing on the date of the final prospectus relating to the Company’s Initial Public Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred
eighty (180) days), which period may be extended upon the request of the managing underwriter, to the extent required by any FINRA rules, for an additional period of up to fifteen (15) days if the Company issues or proposes to issue an
earnings or other public release within fifteen days of the expiration of the expiration of the 180-day lockup period, (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to
sell, grant any option, right, or warrant to purchase, or otherwise Transfer or dispose of, directly or indirectly, any Shares held immediately prior to the effectiveness of the registration statement for the Company’s Initial Public Offering
or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Shares, whether any such transaction described in clause (i) or (ii) above is to be
settled by delivery of Shares or other securities, in cash, or otherwise. The foregoing provisions of this Section 3.11 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall be
applicable to the Holders only if all shareholders holding at least one percent (1%) of the Company’s outstanding Common Stock (after giving effect to conversion into Common Stock of all outstanding Preferred Stock), and all officers and
directors of the Company are subject to the same restrictions. Any discretionary waiver or termination of the provisions of this 








 Shareholders Agreement – Page 16 

 

 
Section 3.11 by the Company or the managing underwriter shall apply to all persons subject to this Section 3.11 on a pro rata basis (calculated on an as-converted basis).
Each Security Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 3.11 or that are necessary to give further
effect thereto. The Company further agrees that it shall use its best efforts to ensure that all shares of capital stock issued after the Effective Time shall be subject to “market stand-off” provisions at least as restrictive as those set
forth in this Section 3.11. 
 3.12 Benefit. This Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective heirs, executors, personal representatives, successors and permitted assigns and shall be binding upon any Person to whom any Shares are Transferred (even if in violation of the provisions of this Agreement) and the
heirs, executors, personal representatives, successors and assigns of such person, firm, company or other entity. No provision of this Agreement shall be construed to provide a benefit to any party hereto who no longer owns any Shares, other than a
right to receive a required payment with respect thereto. 
 3.13 Permitted Transfers. Notwithstanding anything to the contrary in
this Agreement, without complying with any other provisions of this Agreement, a Security Holder may Transfer any or all of such Security Holder’s Shares: 

(a) by way of gift for estate planning purposes to any member of such Security Holder’s family; 

(b) by will or the laws of descent and distribution (in which event each such transferee shall be bound by all of the provisions of this
Agreement to the same extent as if such transferee were the transferring Security Holder); 
 (c) to a trust (i) in respect of which
such Security Holder and his or her family members serve as trustee(s), provided that the trust instrument governing such trust shall provide that Security Holder and his or her family as trustee(s), shall retain sole and exclusive control over the
voting and disposition of such shares until the termination of this Agreement and (ii) which is for the benefit of any member or members of such Security Holder’s family; 

(d) to any of such Security Holder’s partners of the Security Holder if the Security Holder is a partnership, members of the Security
Holder if the Security Holder is a limited liability company, or shareholders of the Security Holder if the Security Holder is a corporation; 

(e) if such Security Holder is an Investor, to any Affiliate of such Investor; 

(f) if such Security Holder is a trust, to a beneficiary or beneficiaries of such trust; 

(g) if such Security Holder is an RRSP or tax free savings account or comparable entity, then to a beneficiary or beneficiaries of such trust;









 Shareholders Agreement – Page 17 

 

 (h) if such Shareholder is a trust or corporation, such Shareholder may Transfer to another
trust or corporation so long as (i) immediately after such Transfer, the beneficiaries of such new trust or the equityholders of such new corporation consist solely of the beneficiaries or equityholder of such Shareholder or members of their
immediate families and (ii) such Transfer is approved by the Board; or 
 (i) to a corporation wholly owned by the Security Holder,
provided that the Security Holder retains sole and exclusive control over the voting and disposition of such Shares and the shares of capital stock of such corporation until the termination of this Agreement (each such transferee as described in
clauses (a) through (f), a “Permitted Transferee”); provided that any such Transfer shall not require the registration of any Shares under the Securities Act or other applicable law. 

Each Security Holder shall vote its Shares to give effect to this Section 3.13, whether at a meeting of Security Holders or by written resolution
of the Security Holders. 
 No Transfer of Shares to a Permitted Transferee shall be effective if the purpose of such Transfer shall have been to circumvent
the provisions of this Agreement. Any Transfer of Shares to a Permitted Transferee pursuant to this Section 3.13 shall be expressly conditioned upon the transferee of such Shares becoming a party to this Agreement by executing an
Instrument of Adherence, in which event each such transferee shall be bound by all of the provisions of this Agreement to the same extent as if such transferee were the transferor, and all Shares transferred shall at all times remain subject to the
terms of this Agreement in the hands of the transferee. As used herein, the word “family” shall include any spouse, lineal ancestor or descendant, brother, sister, or legally adopted child of any such person. 

Notwithstanding compliance with the terms and provisions of this Agreement and in addition to and not in substitution of any other restrictions on Transfer
contained in this Agreement, no holder of Common Shares or Class B Special Shares holding less than 5% of the issued and outstanding Common Shares and Class B Special Shares (on a class by class and fully diluted basis) shall be entitled to sell,
dispose or otherwise transfer their Common Shares or Class B Special Shares, as the case may be, without the prior written approval of the Board, other than to a Permitted Transferee.

 Shareholders Agreement – Page 19 

 

 (a) In the event that the Shareholders who hold the Class B Special Shares are entitled by
operation of law or otherwise to vote at any meeting of Security Holders separately as a class, then the holders of the Class B Special Shares covenant to vote their Class B Special Shares in the same manner as they have voted their Common Shares,
or in the event such Shareholders are not also owners of Common Shares, then in accordance with the manner in which their related parties voted their Common Shares. 

(b) No dividend shall be payable on the Class A Special Shares or Class B Special Shares as long as any Class A Preferred Shares
remain outstanding. 
 (c) No Class A Special Shares or Class B Special Shares shall be redeemed by the Company as long as any

 4.5 Entire Agreement; Amendment. This Agreement constitutes the entire agreement
of the parties with respect to the subject matter hereof. No provision of this Agreement may be amended, modified or waived except by an instrument in writing executed by the Company, the Shareholders holding a majority of the then outstanding
Common Shares held by all Shareholders and the Investors holding a majority of the then outstanding Common Shares held by all Investors (in each case, determined on an as-converted basis); provided, however, that any party may waive
its rights under any provision of this Agreement by delivering to the Company an instrument in writing executed by such party. The Company may not, without the prior written consent of the Investors holding a majority of the outstanding Common
Shares (determined on an as-converted basis), waive any provision of this Agreement. Any waiver by any party of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach of that provision or
of any other provision hereof. 
 4.6 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of
the Province of Ontario (other than its rules of conflicts of laws to the extent that the application of the laws of another jurisdiction would be required thereby) and the laws of Canada applicable in the Province of Ontario. 

4.7 Additional Parties. The Company shall take all necessary action to ensure that each person who shall after the date hereof acquires
any shares of the capital stock of the Company or securities of the Company exercisable or convertible into such number of shares of capital stock of the Company shall become a party to this Agreement by executing and delivering to the Company an
Instrument of Adherence, and such additional party shall thereafter be added to Schedule I or Schedule II hereto, as appropriate, and be deemed a Shareholder or Investor, as appropriate, for all purposes of this Agreement without the
requirement of consent of the other parties hereto. 
 4.8 Severability. If any provision of this Agreement is invalid, illegal or
unenforceable, that provision will, to the extent possible, be modified in such manner as to be valid, legal and enforceable but so as to most nearly retain the intent of the parties hereto as expressed herein. If such a modification is not
possible, the parties hereto shall negotiate in good faith a modification of such provision that reflects as closely as possible the economic purpose of the invalid, illegal or unenforceable provision. If no agreement with respect to such
modification is reached, the invalid, illegal or unenforceable provision will be severed from this Agreement. 








 Shareholders Agreement – Page 20 

 

 
In any case, the validity, legality and enforceability of the remaining provisions of this Agreement will not in any way be affected or impaired thereby for so long as the economic or legal
substance of the transactions contemplated hereby is not effected in any manner materially adverse to any party. 
 4.9 Captions.
Captions are for convenience only and are not deemed to be part of this Agreement. 
 4.10 Counterparts; Signatures. This Agreement
may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. This Agreement may be executed and transmitted by facsimile or other means of electronic communication,
which signature shall be binding upon the parties as if they were original signatures. 
 4.11 Aggregation of Stock. All Shares held
or acquired by affiliates of a Security Holder shall be aggregated together for purposes of determining the availability or discharge of any rights of such Security Holder under this Agreement. 

4.12 Assignment. The rights of the Investors hereunder are assignable by each Investor (i) to any other Investor or (ii) to a
constituent, partner, member, shareholder or Affiliate of such Investor. 
 4.13 Removal of Rights of Investors. The rights and
preferences granted to the Investors in this Agreement shall be of no further force and effect in the event that the Investors and their permitted assigns and Affiliates collectively cease to hold thirty-three and one-third percent (33 1/3%) of the
Class A Preferred Shares originally issued to the Investors, and in such case any preferential rights granted pursuant to the Investors and their permitted assigns and Affiliates as holders of the Class A Preferred Shares or otherwise
shall terminate; provided that any Class A Preferred Shares held by any person who shall become an Investor after the Effective Time shall not be included as Class A Preferred Shares held by the Investors for purposes of this
Section 4.13, except to the extent such Person is, with respect to Investors as of the date hereof, an Affiliate of such Investor. 

4.14 Beneficiaries to Cause Plan Trustees to Act. Any person executing this Agreement as the beneficiary of a registered retirement
savings plan (“RRSP”) or tax free savings account (“TFSA”) personally convenants that they shall take all action(s) necessary to cause the trustee(s) of any applicable RRSP or TFSA to carry out the intentions of
this Agreement. 
 4.15 Mutual Drafting. The parties have participated jointly in the negotiation and drafting of this Agreement and
the other agreements, documents and instruments executed and delivered in connection herewith with counsel sophisticated in transactions similar to those contemplated hereby. In the event an ambiguity or question of intent or interpretation arises,
this Agreement and the agreements, documents and instruments executed and delivered in connection herewith shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any provisions

 EXHIBIT B 

FORM OF EMPLOYEE CONFIDENTIALITY AND ASSIGNMENT AGREEMENT 

WESCOM SOLUTIONS, INC. 

Employee Confidentiality and Assignment Agreement 

In consideration and as a condition of my employment or continued employment by Wescom Solutions, Inc. (the “Company”) and/or any of its affiliates
(the Company or any direct or indirect parent or subsidiary entity of the Company, a “Company Entity”), I agree as follows: 

 

 1. Proprietary Information. I agree that all information, whether or not in writing, concerning
the Company Entities’ business, technology, business relationships or financial affairs that the Company Entities have not released to the general public (collectively, “Proprietary Information”) is and will be the exclusive property
of the Company Entities. By way of illustration, Proprietary Information may include information or material which has not been made generally available to the public, such as: (a) corporate information, including plans, strategies,
methods, policies, resolutions, negotiations or litigation; (b) marketing information, including strategies, methods, customer identities or other information about customers, prospect identities or other information about prospects, or
market analyses or projections; (c) financial information, including cost and performance data, debt arrangements, equity structure, investors and holdings, purchasing and sales data and price lists; and (d) operational and
technological information, including plans, specifications, manuals, forms, templates, software, designs, methods, procedures, formulas, discoveries, inventions, improvements, concepts and ideas; and (e) personnel information,
including personnel lists, reporting or organizational structure, resumes, personnel data, compensation structure, performance evaluations and termination arrangements or documents. Proprietary Information also includes information received in
confidence by the Company Entities from their respective customers or suppliers or other third parties. 
 2. Recognition of Company’s
Rights. I will not, at any time, without the Company’s prior written permission, either during or after my employment, disclose any Proprietary Information to anyone outside of the Company Entities, or use or permit to be used any
Proprietary Information for any purpose other than the performance of my duties as an employee of the Company Entity. I will cooperate with the Company and use my best efforts to prevent the unauthorized disclosure of all Proprietary Information. I
will deliver to the Company all copies of Proprietary Information in my possession or control upon the earlier of a request by the Company or termination of my employment. 

3. Rights of Others. I understand that the Company Entities are now and may hereafter be subject to non-disclosure or confidentiality agreements
with third persons which require the Company Entities to protect or refrain from use of proprietary information. I agree to be bound by the terms of such agreements in the event I have access to such proprietary information, provided I am made aware
of such terms. 


 4. Commitment to Company; Avoidance of Conflict of Interest. While an employee of the Company, I
will devote my full-time efforts to the business of the Company and I will not engage in any other business activity that conflicts with my duties to the Company. I will advise the president of the Company or his or her nominee at such time
as any activity of either the Company Entities or another business presents me with a conflict of interest or the appearance of a conflict of interest as an employee of the Company. I will take whatever action is reasonably requested of me by the
Company to resolve any conflict or appearance of conflict which it finds to exist. 
 5. Developments. I will make full and prompt disclosure
to the Company of all inventions, discoveries, designs, developments, methods, modifications, improvements, processes, algorithms, databases, computer programs, formulae, techniques, trade secrets, graphics or images, and audio or visual works and
other works of authorship (collectively “Developments”), whether or not patentable or copyrightable, that are created, made, conceived or reduced to practice by me (alone or jointly with others) or under my direction during the period of
my employment. I acknowledge that all work performed by me is on a “work for hire” basis, and that all such work is made in the course of my employment, and I hereby do assign and transfer and, to the extent any such assignment cannot be
made at present, will assign and transfer, to the Company and its successors and assigns all my right, title and interest in all Developments that (a) relate to the business of any Company Entity or any customer of or supplier to any Company
Entity or any of the products or services being researched, developed, manufactured or sold by any Company Entity or which may be used with such products or services; or (b) result from tasks assigned to me by a Company Entity; or
(c) result from the use of premises or personal property (whether tangible or intangible) owned, leased or contracted for by the Company Entity (“Company-Related Developments”), and all related patents, patent applications, industrial
designs, industrial design applications, trademarks and trademark applications, copyrights and copyright applications, and other intellectual property rights in all countries and territories worldwide and under any international conventions
(“Intellectual Property Rights”). 
 To preclude any possible uncertainty, I have set forth on Exhibit A attached hereto a complete list of
Developments that I have, alone or jointly with others, conceived, developed or reduced to practice prior to the commencement of my employment with a Company Entity that I consider to be my property or the property of third parties and that I wish
to have excluded from the scope of this Agreement (“Prior Inventions”). If disclosure of any such Prior Invention would cause me to violate any prior confidentiality agreement, I


 









 
understand that I am not to list such Prior Inventions in Exhibit A but am only to disclose a cursory name for each such invention, a listing of the party(ies) to whom it belongs and the
fact that full disclosure as to such inventions has not been made for that reason. I have also listed on Exhibit A all patents and patent applications in which I am named as an inventor, other than those which have been assigned to the
Company (“Other Patent Rights”). If no such disclosure is attached, I represent that there are no Prior Inventions or Other Patent Rights. If, in the course of my employment with the Company, I incorporate a Prior Invention into a Company
product, process or machine or other work done for the Company, I hereby grant to the Company a nonexclusive, royalty-free, paid-up, irrevocable, worldwide license (with the full right to sublicense) to make, have made, modify, use, sell, offer for
sale and import such Prior Invention. Notwithstanding the foregoing, I will not incorporate, or permit to be incorporated, Prior Inventions in any Company-Related Development without the Company’s prior written consent. 

This Agreement does not obligate me to assign to the Company any Development which, in the sole judgment of the Company, reasonably exercised, is developed
entirely on my own time and does not relate to the business efforts or research and development efforts in which, during the period of my employment, the Company actually is engaged or reasonably would be engaged, and does not result from the use of
premises or equipment owned or leased by the Company. However, I will also promptly disclose to the Company any such Developments for the purpose of determining whether they qualify for such exclusion. I understand that to the extent this Agreement
is required to be construed in accordance with the laws of any state which precludes a requirement in an employee agreement to assign certain classes of inventions made by an employee, this paragraph 5 will be interpreted not to apply to any
invention which a court rules and/or the Company agrees falls within such classes. I also hereby waive all claims to any moral rights or other special rights which I may have or accrue in any Company-Related Developments.] 

6. Documents and Other Materials. I will keep and maintain adequate and current records of all Proprietary Information and Company-Related
Developments developed by me during my employment, which records will be available to and remain the sole property of the Company at all times. 
 All
files, letters, notes, memoranda, reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification sheets, program listings, blueprints, models, prototypes, or other written, photographic or other

 7. Enforcement of Intellectual Property Rights. I will cooperate
fully with the Company, both during and after my employment with a Company Entity, with respect to the procurement, maintenance and enforcement of Intellectual Property Rights in Company-Related Developments. I will sign, both during and after the
term of this Agreement, all papers, including without limitation copyright applications, patent applications, declarations, oaths, assignments of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to
protect its rights and interests in any Company-Related Development. If the Company is unable, after reasonable effort, to secure my signature on any such papers, I hereby irrevocably designate and appoint each officer of the Company as my agent and
attorney-in-fact to execute any such papers on my behalf, and to take any and all actions as the Company may deem necessary or desirable in order to protect its rights and interests in any Company-Related Development. 

8. Non-Competition.  
 During my employment
and for a period of twelve (12) months immediately following the termination of my employment , or for such longer period, up to an aggregate maximum of 18 months, during which the Company is paying salary continuation, for any reason (the
“Restricted Period”), I will not directly or indirectly, whether as owner, partner, shareholder, director, manager, consultant, agent, employee, co-venturer or otherwise, engage, participate or invest in any business activity anywhere in
the United States or Canada that develops, manufactures or markets any products, or performs any services, that are otherwise competitive, in a material manner, with the products or services of the Company, or products or services that the Company
Entities or their respective affiliates, has, with my assistance or involvement, under development or that to my knowledge are the subject of active planning at any time during my employment; provided that this shall not prohibit any possible
investment in publicly traded stock of any company or entity representing less than one percent of the stock of such company or entity. 
 9.
Non-Solicitation. 
 In addition, during the Restricted Period, I will not, directly or indirectly, in any manner, other than for the benefit of
the Company Entities, (a) call upon, solicit, divert, take away, or conduct any business from or with any of the Customers or Prospective Customers of the Company Entities or any of its suppliers, and/or (b) solicit, entice, attempt to
persuade any other employee or consultant of the Company Entities to leave the Company Entities for any reason or otherwise participate


 


  
  2 









 
in or facilitate the hire, directly or through another entity, of any person who is employed or engaged by the Company Entities or who was employed or engaged by the Company Entities within six
months of any attempt to hire such person. “Customer” shall mean any person who, in the twelve (12) months preceding the date of the termination of my employment hereunder for any reason, has purchased from any of the Company
Entities, with my assistance, any product or services produced, sold, licensed, or distributed by any of the Company Entities. “Prospective Customer” shall mean any person solicited by me, on behalf of any Company Entity at any time
during the twelve (12) month period immediately preceding the date of the termination of my employment, for any reason. 
 10. Government
Contracts. I acknowledge that the Company may have from time to time agreements with other persons or with the United States Government or its agencies which impose obligations or restrictions on the Company regarding inventions made during
the course of work under such agreements or regarding the confidential nature of such work. I agree to comply with any such obligations or restrictions upon the direction of the Company. In addition to the rights assigned under paragraph 5, I also
assign to the Company (or any of its nominees) all rights which I have or acquired in any Developments, full title to which is required to be in the United States under any contract between the Company and the United States or any of its agencies.

 11. Prior Agreements. I hereby represent that, except as I have fully disclosed previously in writing to the Company, I am not bound by the
terms of any agreement with any previous employer or other party to refrain from using or disclosing any trade secret or confidential or proprietary information in the course of my employment with the Company or to refrain from competing, directly
or indirectly, with the business of such previous employer or any other party. I further represent that my performance of all the terms of this Agreement as an employee of the Company does not and will not breach any agreement to keep in confidence
proprietary information, knowledge or data acquired by me in confidence or in trust prior to my employment with the Company. I will not disclose to the Company or induce the Company to use any confidential or proprietary information or material
belonging to any previous employer or others. 
 12. Remedies Upon Breach. I understand that the restrictions contained in this Agreement are
necessary for the protection of the business and goodwill of the Company and I consider them to be reasonable for such purpose. Any breach of this Agreement is likely to cause the Company substantial and irrevocable damage and therefore, in the
event of such breach, the Company, in addition to such other remedies which may be available, will be entitled to specific performance and other injunctive relief, without the posting of a bond. 

13. Use of Voice, Image and Likeness. While I am employed by the Company Entities, I give the Company permission to use any and all of my voice,
image and likeness, with or without using my name, in connection with the

Company in its reasonable discretion, except to the extent expressly prohibited by law. 
 14. Publications and Public Statements. I will
obtain the Company’s written approval before publishing or submitting for publication any material that relates to my work at the Company and incorporates any Proprietary Information. To ensure that the Company delivers a consistent message
about its products, services and operations to the public, and further in recognition that even positive statements may have a detrimental effect on the Company in certain securities transactions and other contexts, any statement about the Company
which I create, publish or post during my period of employment and for six (6) months thereafter, on any media accessible by the public, including but not limited to electronic bulletin boards and Internet-based chat rooms, must first be
reviewed and approved by an officer or other designated person of the Company before it is released in the public domain. 
 15. Survival and
Assignment by the Company. I understand that my obligations under this Agreement will continue in accordance with its express terms regardless of any changes in my title, position, duties, salary, compensation or benefits or other terms and
conditions of employment. I further understand that my obligations under this Agreement will continue following the termination of my employment regardless of the manner of such termination and will be binding upon my heirs, executors and
administrators. The Company will have the right to assign this Agreement to its affiliates, successors and assigns. I expressly consent to be bound by the provisions of this Agreement for the benefit of the Company or any Company Entity or any of
their respective parents, subsidiaries or affiliates to whose employ I may be transferred without the necessity that this Agreement be resigned at the time of such transfer. 

16. Exit Interview. If and when I depart from the Company, I may be required to attend an exit interview and sign an “Employee Exit
Acknowledgement” to reaffirm my acceptance and acknowledgement of the obligations set forth in this Agreement. 
 17. Disclosure to Future
Employers. I will provide a copy of this Agreement to any prospective employer, partner or coventurer prior to entering into an employment, partnership or other business relationship with such person or entity. 

18. Severability. In case any provisions (or portions thereof) contained in this Agreement shall, for any reason, be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been
contained herein. 

 


  
  3 








 
 19. Interpretation. This Agreement will be deemed to be made and entered into in the Province of
Ontario, Canada, and will in all respects be interpreted, enforced and governed under the laws of the Province of Ontario, Canada. I hereby agree to consent to jurisdiction of the courts situated within the Province of Ontario, Canada for purposes
of enforcing this Agreement, and waive any objection that I might have to personal jurisdiction or venue in those courts. 
 20. Entire
Agreement. This Agreement and the Employment Agreement between myself and [            ] dated as of
[            ], supersedes all prior understandings and agreements between




 
myself and the Company Entities relating to the subject matter hereof and constitutes the entire agreement between the parties. 

21. Legal Advice. I acknowledge and agree that the Company has recommended that I obtain independent legal advice with respect to the nature and
consequences of entering into this Agreement, which legal advice cannot and will not be provided by counsel to the Company Entities. By signing and accepting this Agreement, I acknowledge that I have had the opportunity to obtain or have obtained

FORM OF CONSULTING AGREEMENT 

CONSULTING SERVICES AGREEMENT 

THIS CONSULTING SERVICES AGREEMENT (“Agreement”) is entered into this          day of
                 2007 (“Effective Date”) by and between
                                         
                            with principal address at

part thereof, whether tangible or intangible, including any and all technology, software, documentation, system architecture, designs, drawings, layouts, graphics, business plans, materials, methods, techniques, processes, ideas, inventions,
discoveries, improvements, know-how and information created or conceived previously or in the future, in whole or in part, by Consultant, or jointly with others, in the performance of any duties for the Company or the provision of Services
hereunder, or otherwise derived from the Company’s Confidential Information. 
  

	2.	Services, Fees and Warranties 

 2.1. From time to time, Company and Consultant may agree
on certain Services to be provided by Consultant under this Agreement, and shall prepare and execute a Statement of Work. Consultant shall provide the Services in accordance with any requirements set out in such Statement of Work and the terms of
this Agreement. Consultant may not use subcontractors to provide the Services or Work Product hereunder unless Company agrees in writing in advance. Consultant shall report fully on the Services being provided to Company and advise to the best of
Consultant’s ability and in accordance with reasonable business standards on matters related to the provision of such Services that may arise from time to time during the term of this Agreement. 

2.2. Company agrees to pay Consultant the fees set forth in the applicable Statement of Work in consideration for Consultant’s provision
of the Services. Consultant is responsible for the payment of any taxes relating to the fees. If such fees are to be paid on a fixed fee or milestone 

  
 1 








 
basis, such fees shall be paid in arrears, within thirty (30) days following receipt of Consultant’s invoice and after acceptance of the applicable milestone deliverable. Consultant
shall be solely responsible for Consultant’s own expenses in relation to performing any Services unless specifically provided otherwise under the applicable Statement of Work. 

2.3. Consultant represents and warrants to Company that: (a) Consultant shall provide the Services to the Company in a professional and
workmanlike manner and in accordance with generally accepted industry standards; (b) the Work Product is, and shall be, the original work of the Consultant and does not, and shall not, infringe upon the Intellectual Property Rights of any third
party; (c) Consultant is not currently, and shall not in the future become, a party to any agreement or relationship that may be in conflict with Consultant’s obligations under this Agreement; (d) Consultant shall not use in
Company’s business, or cause Company to use, any information or material which is confidential information or a trade secret of any third party unless such third party authorizes Company to receive and use such information or material; (e)
Consultant has not granted any rights to the Work Product to any third party and the Work Product is free and clear of any liens, encumbrances, security interests and restrictions on transfer; and (f) the Work Product does not and will not
contain any virus, trap door, worm, root kit, spy ware or any other device that is otherwise injurious, intrusive or damaging to software or hardware that may be used in conjunction with the Work Product. 

 

	3.	Intellectual Property Rights 

 3.1. Consultant agrees that the Work Product developed by
Consultant is and shall be the sole and exclusive property of Company and Company shall own all right, title and interest in and to the Work Product, including all Intellectual Property Rights therein from the time of creation of such Work Product.
To the extent Consultant should have any rights to any Work Product by operation of law or otherwise, Consultant hereby irrevocably assigns and transfers to Company all of Consultant’s right, title and interest, including all Intellectual
Property Rights, Consultant may have in or to the Work Product. Consultant hereby irrevocably waives any and all moral rights, and other similar rights existing at common law or statute, in and to the Work Product. Consultant represents that it has
secured, and will continue to secure, all such rights, including moral rights assignments, waivers and releases, from any third party, including its employees, which Consultant uses to provide the Services and develop the Work Product. 

3.2. On and after the date of this Agreement, Consultant shall, at the expense of the Company, do, execute, acknowledge and deliver such
further acts, deeds, transfers and assurances as the Company shall reasonably require for better assuring, assigning and conferring unto the Company all right, title, and interest in and to the Work Product, including the disclosure to Company of
all pertinent information and data with respect thereto. Without limiting the foregoing, Consultant will assist Company, in filing and prosecuting Canadian, United States and foreign patent applications claiming any Work Product, or part thereof,
including applying for, in Consultant’s name or otherwise, and at the direction, request and expense of the Company, for Canadian, United States and foreign letters patent for any invention. Consultant shall acknowledge in writing (including
under oath, as deemed necessary by the Company), and shall do such other acts required by the Company, at the Company’s request and expense, to apply for, obtain and maintain Canadian, United States and/or foreign letters patent for each
invention and to vest the entire right and title to such invention in the Company. Consultant further irrevocably constitutes and appoints Company as Consultant’s true and lawful attorney with full power of 

  
 2 








 
substitution in the name of and on behalf of Consultant in accordance with The Powers of Attorney Act (Ontario), with no restriction or limitation in that regard, to execute and deliver
all such agreements and documents as may be necessary to permit any patent application to be completed as provided in this Agreement. 

3.3. Subject to Company’s rights to the Work Product and Consultant’s obligations with respect to Confidential Information
(as defined in Section 4.1 below), Consultant shall be free to provide similar services to any other person, however Consultant agrees that he shall not at any time sell, market, license or otherwise make available to any entity or person
that is a competitor of Wescom any software that is the same as, similar to or competitive with the Work Product or any part thereof, or any derivative work or part thereof based on the Work Product. Consultant also agrees that the restrictions in
this Section shall apply to the Consultant and all present and future affiliates, as defined under the Business Corporations Act (Ontario), of the Consultant. Consultant agrees that the restrictions set out in this Section are reasonable
given the payment to be made by Company to Consultant in respect of the Services, and given the fact that the restrictions in this Section represent a fundamental element of the transaction between Company and Consultant. 

 

	4.	Confidential Information 

 4.1. “Confidential Information” means any and all
information of or relating to Company, including any subsidiary or affiliate thereof, that Company considers to be proprietary or confidential, that is accessible or disclosed to Consultant, either directly or indirectly, in writing, electronically,
orally, by inspection or otherwise, including without limitation information relating to software, proposals, specifications, quotations, documents, prototypes, samples, models, designs, technical data, test results, demonstrations, evaluation
materials, analyses, trade secrets, know-how, show-how, product plans, products, services, customer names and information, markets, inventions, procedures, practices, processes, drawings, business plans, marketing plans, financial information,
Company’s plant and equipment, and the terms of this Agreement, any Statement of Work, and the relationship between Company and Consultant, and includes information created by Consultant hereunder. 

4.2. Consultant agrees that the Confidential Information and the Services provided to Company hereunder are sensitive and proprietary to
Company. Consultant will not use the Confidential Information except for the benefit of the Company and as necessary for Consultant’s performance of Services hereunder. Consultant will use its best efforts to protect the Confidential
Information from disclosure. Consultant will not disclose Confidential Information to any third party. Consultant shall take all reasonable precautions to prevent any unauthorized disclosure of Confidential Information including having each employee
of Consultant, if any, with a need-to-know the Confidential Information, execute a nondisclosure agreement containing provisions in Company’s favour identical to this Article 4, and the Consultant shall provide Company with executed copies of
any such non-disclosure agreements if requested by Company. 
 4.3. The foregoing restrictions will not apply to Confidential Information
that Consultant can establish by clear and convincing evidence, (i) was in the public domain prior to the date hereof or becomes public hereafter through no fault of Consultant; (ii) was provided to Consultant by a third party who is not
in violation of a duty of confidentiality with respect to that information; or (iii) is required by law or court order to be disclosed by the Consultant, provided 

  
 3 








 
that the Consultant gives the Company prompt written notice of such requirement prior to such disclosure and assistance in obtaining an order protecting the information from public disclosure.

 4.4. Upon the earlier of termination of this Agreement or notice from the Company to Consultant, Consultant shall immediately return to
Company any and all documents, papers and other materials, whether tangible or intangible, comprising Confidential Information that are in the possession or under the control of Consultant. Consultant acknowledges that any breach or threatened
breach of any provision of this Article 4 will cause irreparable harm to Company and will entitle Company to an injunction or other form of equitable relief in addition to all other legal remedies. 

 

	5.	Term and Termination 

 5.1. The term of this Agreement shall commence on the Effective
Date first set out above and continue until termination in accordance with the provisions of this Agreement. 
 5.2. The Company may
terminate this Agreement or any Statement of Work hereunder upon fifteen (15) days’ written notice to Consultant without cause. In the event of termination under the foregoing provision, Company’s sole liability to Consultant shall be
payment of either: (i) the fees for any satisfactory Services provided before the effective date of termination if payment under the Statement of Work is on a time and materials basis; or (ii) if payment under the Statement of Work is
milestone-based or a fixed fee, a pro-rata proportion of the next milestone payment or the fixed fee, as the case may be, that fairly reflects the amount of work completed towards the next uncompleted milestone, in the sole opinion of the Company,
in every case less any offsets against such fees that the Company may be entitled to recover. Despite the foregoing, the Company may terminate this Agreement and/or any Statement of Work hereunder immediately without payment of any fees if
Consultant refuses to or is unable to provide the Services or breaches any provision of this Agreement or a Statement of Work. 
 5.3. The
provisions of Section 2.3 and 2.4 and Articles 1, 3, 4, 5, 6 and 7 shall survive any termination of this Agreement. 
  

	6.	Non-Solicitation 

 The Consultant will not at any time during the term of this Agreement
or during the period of twenty-four (24) months following the termination of this Agreement for any reason whatsoever, on the Consultant’s own behalf or on behalf of another person or entity competing or endeavoring to compete with
Company, (a) solicit Company customers or induce Company customers to terminate their existing contracts with Company in favour of Consultant, or (b) seek in any way to persuade or entice any employee of or consultant with Company to leave
that employment or consulting relationship. 
  

	7.	Miscellaneous 


  
 4 








 This Agreement shall be governed by the laws of the Province of Ontario and the federal laws of
Canada applicable therein, and the parties hereby submit to the exclusive jurisdiction of the federal and provincial courts in the City of Toronto, Province of Ontario over any matters arising out of this Agreement. It is understood and agreed by
the parties that Consultant is an independent contractor and shall not in any case be considered an employee, agent, partner or representative of Company, nor shall Consultant act or represent itself, directly or by implication, as an agent of
Company or in any manner assume or create any obligation on behalf of, or in the name of, Company. Consultant may not assign, transfer or delegate any of its rights or obligations hereunder. Subject to the foregoing, this Agreement shall inure to
the benefit of and bind the parties and their successors and permitted assigns. Consultant agrees to indemnify, defend and hold harmless Company, and its directors and officers, against any and all taxes, liability, losses, damages, costs and
expenses (including cost of defense and reasonable attorney’s fees) arising from or in connection with (i) any breach by Consultant or Consultant’s employees, permitted subcontractors or agents under Articles 2, 3 or 4, (ii) any
negligent, reckless or intentionally wrongful act or omission of Consultant or Consultant’s employees, permitted subcontractors or agents, or (iii) a determination by any court or government body that Consultant is not an independent
contractor or that Company is liable for any taxes, including any withholding taxes, hereunder. This Agreement, including any Statements of Work incorporated hereunder, sets forth the entire agreement and understanding between the parties with
respect to the subject matter herein and supersedes all prior discussions, understandings and agreements. Company’s liability for damages for any cause and regardless of the form or cause of action, whether in contract or in tort, including
fundamental breach or negligence, shall be limited to direct damages and shall not exceed, in the aggregate, the amounts paid or payable by Wescom to Consultant under this Agreement with respect to the Services. No modification of or amendment to
this Agreement, nor any waiver of any rights under this agreement, will be effective unless in writing signed by the party to be charged. The waiver by either party of a breach of any provision of this Agreement will not operate or be interpreted as
a waiver of any other or subsequent breach. If any provision of this Agreement is found by a court of competent jurisdiction to be unenforceable or void, the remaining provisions will continue in full force and effect, but such unenforceable
provision shall be deemed to be modified to the extent necessary to render it enforceable, preserving to the fullest extent permissible the intent of the parties set forth herein. 

The Consultant acknowledges and agrees that Consultant had the opportunity to seek and was not prevented nor discouraged by Company from seeking independent
legal advice prior to the execution and delivery of this Agreement and that, in the event that Consultant did not avail himself of that opportunity prior to signing this Agreement, he did so voluntarily without any undue pressure and agrees that his
failure to obtain independent legal advice shall not be used by him as a defense to the enforcement of his obligations under this Agreement.
