Explanatory note

This Amendment No. 2 (this “Amendment”) to the Registration Statement on Form S-1 (File No. 333-231789) is being filed solely for the purpose of adding Exhibits 4.1, 5.1, 10.27, 10.28, 10.29 and 23.2, as indicated in Item 16 of Part II of the Registration Statement. This Amendment does not modify any provision of the preliminary prospectus that forms a part of the Registration Statement or Items 13, 14, 15 or 17 of Part II of the Registration Statement. Accordingly, a preliminary prospectus has been omitted.

Part II

Information not required in prospectus

Item 13. Other expenses of issuance and distribution

The following table sets forth all expenses to be paid by the Registrant, other than estimated underwriting discounts and commissions, in connection with this offering. All amounts shown are estimates except for the SEC registration fee, the FINRA filing fee and the exchange listing fee:

Item 14. Indemnification of directors and officers

Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, fraud or the consequences of committing a crime. Our Amended and Restated Memorandum and Articles of Association provide for indemnification of officers and directors for losses, damages, costs and expenses incurred in their capacities as such, except through their own willful default, fraud and dishonesty.

Pursuant to the form of indemnification agreements filed as Exhibit 10.1 to this Registration Statement, we will agree to indemnify our directors and officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being such a director or officer.

The form of Underwriting Agreement filed as Exhibit 1.1 to this Registration Statement will also provide for indemnification of us and our officers and directors in certain instances.

Item 17. Undertakings

The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

Exhibit 5.1

Dear Sirs

CAMBIUM NETWORKS CORPORATION (THE “COMPANY”)

We have been asked to provide this legal opinion to you with regard to the laws of the Cayman Islands in connection with the registration of an initial public offering of 5,800,000 ordinary shares and up to an additional 870,000 ordinary shares which the Underwriters (as defined in Schedule 1) will have a right to purchase from the Company, in each case with a par value of $0.0001 per share in the capital of the Company (the “Offered Shares”) under the United States Securities Act of 1933, as amended (the “Securities Act”) and pursuant to the terms of the Registration Statement (as defined in Schedule 1).

For the purposes of giving this opinion, we have examined and relied upon the originals or copies of the documents listed in Schedule 1.

We are Cayman Islands Attorneys at Law and express no opinion as to any laws other than the laws of the Cayman Islands in force and as interpreted at the date of this opinion.

Based upon the foregoing examinations and the assumptions and qualifications set out below and having regard to legal considerations which we consider relevant, and under the laws of the Cayman Islands, we give the following opinion in relation to the matters set out below.

the Offered Shares will have been duly authorised by all necessary corporate action of the Company and upon the issue of the Offered Shares (by the entry of the name of the registered owner thereof in the Register of Members of the Company confirming that such Offered Shares have been issued credited as fully paid),

delivery and payment therefore by the purchaser in accordance with the Memorandum and Articles of Association (as defined in Schedule 1) and in the manner contemplated by the Registration Statement, the Prospectus and the Underwriting Agreement (as each term is defined in Schedule 1), the Offered Shares will be validly created, legally issued, fully paid and non-assessable (meaning that no additional sums may be levied on the holder thereof by the Company).

The foregoing opinion is given based on the following assumptions.

We have relied upon the statements and representations of directors, officers and other representatives of the Company as to factual matters.

Our opinion as to good standing is based solely upon receipt of the Certificate of Good Standing (as defined in Schedule 1) issued by the Registrar. The Company shall be deemed to be in good standing under section 200A of the Companies Law on the date of issue of the certificate if all fees and penalties under the Companies Law have been paid and the Registrar has no knowledge that the Company is in default under the Companies Law.

This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein. This opinion is given solely for your benefit and the benefit of your legal advisers acting in that capacity in relation to this transaction and may not be relied upon by any other person, other than persons entitled to rely upon it pursuant to the provisions of the Securities Act, without our prior written consent.

This opinion shall be construed in accordance with the laws of the Cayman Islands.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. We also hereby consent to the reference to this firm in the Prospectus.

2019 SHARE INCENTIVE PLAN

RESTRICTED SHARE UNIT AWARD AGREEMENT

Cambium Networks Corporation, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), hereby grants to the individual (the “Holder”) named in the award notice attached hereto (the “Award Notice”) as of the date set forth in the Award Notice (the “Grant Date”), pursuant to the provisions of the Cambium Networks Corporation 2019 Share Incentive Plan (the “Plan”), a restricted share unit award (the “Award”) with respect to the number of ordinary shares of the Company, par value $0.0001 per share (“Shares”), set forth in the Award Notice, upon and subject to the restrictions, terms and conditions set forth in the Plan and this agreement (the “Agreement”). Capitalized terms not defined herein shall have the meanings specified in the Plan.

1. Award Subject to Acceptance of Agreement. The Award shall be null and void unless the Holder accepts this Agreement by executing the Award Notice in the space provided therefor and returning an original execution copy of the Award Notice to the Company (or electronically accepts this Agreement within the Holder’s share plan account with the Company’s share plan administrator according to the procedures then in effect). In addition, in the event that the Company’s initial public offering of the Ordinary Shares does not close on or before September 30, 2019, this Award shall be forfeited as of such date.

2. Rights as a Shareholder. The Holder shall not be entitled to any privileges of ownership with respect to the Shares subject to the Award unless and until, and only to the extent, such Shares become vested pursuant to Section 3 hereof and the Holder becomes a shareholder of record with respect to such shares. As of each date on which the Company pays a cash dividend to record owners of Shares (a “Dividend Date”), then the number of Shares subject to the Award shall increase by (i) the product of the total number of Shares subject to the Award immediately prior to such Dividend Date multiplied by the dollar amount of the cash dividend paid per Share by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a Share on such Dividend Date. Any such additional Shares shall be subject to the same vesting conditions and payment terms set forth herein as the Shares to which they relate.

3. Restriction Period and Vesting.

3.1. Service-Based Vesting Condition. Except as otherwise provided in this Section 4, the Award shall vest in accordance with the vesting schedule set forth in the Award Notice if, and only if, the Holder is, and has been, continuously (except for any absence for vacation, leave, etc. in accordance with the Company’s or its Subsidiaries’ policies): (a) employed by the Company or any of its Subsidiaries; (b) serving as a Non-Employee Director or (c) providing services to the Company or any of its Subsidiaries as an advisor or consultant, in each case, from the date of this Agreement through and including such date. The period of time prior to the vesting shall be referred to herein as the “Restriction Period.”

3.2. Termination due to Death or Disability. If Holder’s employment with the Company terminates prior to the one-year anniversary of the Grant Date by reason of the Holder’s death or a termination by the Company due to Disability, the Holder shall be entitled to a pro-rated Award. Such pro-rated Award shall be equal to 25% of the Ordinary Shares subject to the Award on the Grant Date multiplied by a fraction, the numerator of which shall equal the number of full days in the Restricted Period during which the Holder was employed by the Company and the denominator of which shall equal 365. The portion of the Award that does not become vested under this Section 3.2 shall be immediately forfeited by the Holder and cancelled by the Company.

3.3. Termination other than due to Death or Disability. Except as set forth in any employment or other agreement between the Company or any of its Subsidiaries and the Holder, if the Holder’s employment with the Company terminates prior to the end of the Restriction Period (a) by the Company for any reason other than death or Disability or (b) by the Holder by reason of the Holder’s resignation from employment for any reason, then the portion of the Award that was not vested immediately prior to such termination of employment shall be immediately forfeited by the Holder and cancelled by the Company.

3.4. Change in Control.

(a) In the event of a Change in Control prior to the end of the Restriction Period pursuant to which the Award is not effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the value of the shares subject to the Award and other material terms and conditions of the outstanding Award as in effect immediately prior to the Change in Control), the Award shall vest as of the date of the Change in Control and shall be settled in cash within 70 days following the Change in Control; provided, however, if the Award is considered “nonqualified deferred compensation” within the meaning of Section 409A of the Code and the settlement of such Award upon the Change in Control would result in adverse tax consequences under Section 409A of the Code, then the Award shall be vested and shall be settled upon the earlier to occur of (i) the vesting schedule set forth in the Award Notice and (ii) Holder’s termination of employment.

(b) In the event of a Change in Control prior to the end of the Restriction Period pursuant to which the Award is effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the value of the shares subject to the Award and other material terms and conditions of the outstanding Award as in effect immediately prior to the Change in Control) and (i) the Holder remains continuously employed through the end of the Restriction Period or (ii) the Company terminates the Holder’s employment without Cause or the Holder resigns for Good Reason within 24 months following such Change in Control and the Holder executes and does not revoke a waiver and release of claims in the form prescribed by the Company within 60 days after the date of such termination, the Award shall vest and shall be settled within 70 days following the end of the Restriction Period or, if earlier, the Holder’s termination of employment in accordance with this Section 3.4(b). If, following a Change in Control, the Holder experiences a termination of employment other than as set forth in Section 3.2 or this Section 3.4(b), the Award shall be immediately forfeited by the Holder and cancelled by the Company.

3

materially inconsistent with the positions, authority, duties, responsibilities or status the Holder holds as of the Grant Date, or (C) the Company changes the Holder’s place of work to a location more than fifty (50) miles from the Holder’s present place of work; provided, however, that the occurrence of any such condition shall not constitute Good Reason unless (x) the Holder provides written notice to the Company of the existence of such condition not later than 60 days after the Holder knows or reasonably should know of the existence of such condition, (y) the Company fails to remedy such condition within 30 days after receipt of such notice and (z) the Holder resigns due to the existence of such condition within 60 days after the expiration of the remedial period described in clause (y) hereof.

The Award may not be transferred by the Holder other than by will or the laws of descent and distribution. Except to the extent permitted by the foregoing sentence, the Award may not be sold, transferred, assigned, pledged, charged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, charge, hypothecate, encumber or otherwise dispose of the Award, the Award and all rights hereunder shall immediately become null and void.

5.2. Investment Representation. The Holder hereby represents and covenants that (a) any Share acquired upon the vesting of the Award will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such acquisition has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such Shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of vesting of any Shares hereunder or (y) is true and correct as of the date of any sale of any such Share, as applicable. As a further condition precedent to the delivery to the Holder of any Shares subject to the Award, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Board shall in its sole discretion deem necessary or advisable.

6. Additional Terms and Conditions of Award.

6.1. Withholding Taxes. (a) As a condition precedent to the delivery of the Shares upon vesting of the Award, the Holder shall, upon request by the Company, pay to the Company such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (the “Required Tax Payments”) with respect to the Award. If the Holder shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to the Holder.

(b) The Holder may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (i) a cash payment to the Company; (ii) delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole Shares having an aggregate Fair Market Value, determined as of the date on which such withholding obligation arises (the “Tax Date”), equal to the Required Tax Payments; (iii) authorizing the Company to withhold whole Shares which would otherwise be delivered to the Holder having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments; or (iv) any combination of (i), (ii) and (iii). Shares to be delivered or withheld may not have a Fair Market Value in excess of the minimum amount of the Required Tax Payments (or such higher amount as elected by the Holder and which does not raise adverse accounting consequences). Any fraction of a Share which would be required to satisfy any such obligation shall be disregarded and the remaining amount due shall be paid in cash by the Holder. No Shares shall be delivered until the Required Tax Payments have been satisfied in full.

6.2. Adjustment. In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock Compensation) that causes the per share value of Shares to change, such as a share dividend, share split, spinoff, rights offering or recapitalization through an extraordinary dividend, the terms of this Award, including the number and class of securities subject hereto, shall be appropriately adjusted by the Committee. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of the Holder. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

6.3. Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the Shares subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of Shares hereunder, the Shares subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

5

6.4. Delivery of Shares. Subject to Section 6.1, upon the vesting of the Award, in whole or in part, the Company shall deliver or cause to be delivered to the Holder the vested Shares in accordance with Section 3. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 6.1.

6.5. Award Confers No Rights to Continued Employment. In no event shall the granting of the Award or its acceptance by the Holder, or any provision of the Agreement or the Plan, give or be deemed to give the Holder any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.

6.6. Decisions of Board or Committee. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Award. Any interpretation, determination or other action made or taken by the Board or the Committee regarding the Plan or this Agreement shall be final, binding and conclusive.

6.7. Successors. This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of the Holder, acquire any rights hereunder in accordance with this Agreement or the Plan.

6.8. 409A. This Award is intended to be exempt from or comply with Section 409A of the Code, and shall be interpreted and construed accordingly and each settlement hereunder shall be considered a separate payment. Notwithstanding any other provision in this Award, to the extent any payments hereunder constitute “nonqualified deferred compensation,” within the meaning of Section 409A, then (i) to the extent this Agreement provides for the Award to become vested and be settled upon Holder’s termination of employment, the applicable Award shall be settled upon Holder’s “separation from service” (within the meaning of Section 409A of the Code) even if the Award vests upon an earlier termination of employment and (ii) if Holder is a specified employee (within the meaning of Section 409A of the Code) as of the date of Holder’s separation from service, each such payment that is payable upon Holder’s separation from service and would have been paid prior to the six-month anniversary of Holder’s separation from service, shall be delayed until the earlier to occur of (A) the six-month anniversary of Holder’s separation from service and (B) the date of Holder’s death.

6.9. Notices. All notices, requests or other communications provided for in this Agreement shall be made, if to the Company, to Cambium Networks Corporation, Attn: Share Administration, 3800 Golf Rd Ste 360, Rolling Meadows, IL 60008, and if to the Holder, to the last known mailing address of the Holder contained in the records of the Company. All notices, requests or other communications provided for in this Agreement shall be made in writing either (a) by personal delivery, (b) by facsimile or electronic mail with confirmation of receipt, (c) by mailing in the United States mails or (d) by express courier service. The notice, request or other communication shall be deemed to be received upon personal delivery, upon

6

confirmation of receipt of facsimile or electronic mail transmission or upon receipt by the party entitled thereto if by United States mail or express courier service; provided, however, that if a notice, request or other communication sent to the Company is not received during regular business hours, it shall be deemed to be received on the next succeeding business day of the Company.

6.10. Governing Law. This Agreement, the Award and all determinations made and actions taken pursuant hereto and thereto shall be governed by the laws of the Cayman Islands and construed in accordance therewith without giving effect to principles of conflicts of laws.

6.11. Agreement Subject to the Plan. This Agreement is subject to the provisions of the Plan and shall be interpreted in accordance therewith. In the event that the provisions of this Agreement and the Plan conflict, the Plan shall control. The Holder hereby acknowledges receipt of a copy of the Plan.

6.12. Entire Agreement. This Agreement and the Plan constitute the entire agreement of the parties with respect to the Shares subject to this Award and supersede in their entirety all prior undertakings and agreements of the Company and the Holder with respect to such Shares, and may not be modified adversely to the Holder’s interest except by means of a writing signed by the Company and the Holder.

6.13. Partial Invalidity. The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions hereof and this Agreement shall be construed in all respects as if such invalid or unenforceable provision was omitted.

6.14. Amendment and Waiver. The provisions of this Agreement may be amended or waived only by the written agreement of the Company and the Holder, and no course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

6.15. Counterparts. The Award Notice may be executed in two counterparts, each of which shall be deemed an original and both of which together shall constitute one and the same instrument.

2019 SHARE INCENTIVE PLAN

Share Option Agreement

Cambium Networks Corporation, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), hereby grants to the individual (“Optionee”) named in the award notice attached hereto (the “Award Notice”) as of the date set forth in the Award Notice (the “Option Date”), pursuant to the provisions of the Cambium Networks Corporation 2019 Share Incentive Plan (the “Plan”), an option to purchase from the Company the number of the Company’s ordinary shares, par value $0.0001 per share (“Ordinary Shares”), set forth in the Award Notice at the price per share set forth in the Award Notice (the “Exercise Price”) (the “Option”), upon and subject to the terms and conditions set forth below, in the Award Notice and in the Plan. Capitalized terms not defined herein shall have the meanings specified in the Plan.

1. Option Subject to Acceptance of Agreement. The Option shall be null and void unless Optionee shall accept this Agreement by executing the Award Notice in the space provided therefor and returning an original execution copy of the Award Notice to the Company (or electronically accepting this Agreement within the Optionee’s share plan account with the Company’s share plan administrator according to the procedures then in effect). In addition, in the event that the Company’s initial public offering of the Ordinary Shares does not close on or before September 30, 2019, this Option shall be forfeited as of such date.

2. Time and Manner of Exercise of Option.

2.1. Maximum Term of Option. In no event may the Option be exercised, in whole or in part, after the expiration date set forth in the Award Notice (the “Expiration Date”).

2.2. Vesting and Exercise of Option. The Option shall become vested and exercisable in accordance with the vesting schedule set forth in the Award Notice (the “Vesting Schedule”). The period of time prior to the full vesting of the Option shall be referred to herein as the “Vesting Period.” The Option shall be vested and exercisable following a termination of Optionee’s employment according to the following terms and conditions:

(a) Termination due to Death or Disability. If the Optionee’s employment with the Company terminates prior to the one-year anniversary of the Option Date by reason of the Optionee’s death or a termination by the Company due to Disability, a pro-rated portion of the Option shall be vested and exercisable upon such termination. Such pro-rated portion shall be equal to 25% of shares subject to the Option on the Option Date multiplied by a fraction, the numerator of which shall equal the number of full days in the Vesting Period during which the Optionee was employed by the Company and the denominator of which shall equal 365. The vested portion of the Option may thereafter be exercised by Optionee or Optionee’s executor, administrator, legal representative, guardian or similar person until and including the earlier to occur of (i) the date which is one year after the date of termination of employment and (ii) the Expiration Date. The portion of the Option that does not become vested under this Section 2.2(a) shall be immediately forfeited by the Optionee and cancelled by the Company.

(b) Termination other than for Cause, Death, or Disability. Except as set forth in any employment or other agreement between the Company or any of its Subsidiaries and the Optionee, if Optionee’s employment with the Company terminates prior to the end of the Vesting Period by reason of a termination of Optionee’s employment (i) by the Company for any reason other than for Cause, death or Disability or (ii) by the Optionee for any reason, the Option, only to the extent vested on the effective date of such termination of employment, may thereafter be exercised by Optionee until and including the earlier to occur of (i) the date which is ninety (90) days after the date of such termination of employment and (ii) the Expiration Date.

(c) Termination for Cause. If Optionee’s employment with the Company terminates by reason of the Company’s termination of Optionee’s employment for Cause, then the Option, whether or not vested, shall terminate immediately upon such termination of employment.

(d) Change in Control. In the event of a Change in Control prior to the end of the Vesting Period pursuant to which the Option is not effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the intrinsic value and other material terms and conditions of the outstanding Option as in effect immediately prior to the Change in Control and in accordance with Section 409A of the Code), the Option shall be 100% vested immediately prior to such Change in Control and the Optionee shall receive in full settlement for such Option a cash payment in an amount equal to the aggregate number of Ordinary Shares then subject to the Option multiplied by the excess, if any, of the Fair Market Value of an Ordinary Share as of the date of the Change in Control, over the Exercise Price.

(e) Definitions.

(i) Cause. For purposes of this Option, (i) “Cause” shall have the meaning assigned to such term in any written employment or similar agreement between the Company or any of its Subsidiaries and the Optionee in effect on the Grant Date or (ii) if the Optionee is not party to an employment or similar agreement in effect on the Grant Date and which defines “Cause,” then “Cause” shall mean one or more of the following: (A) Optionee’s refusal (after written notice and reasonable opportunity to cure) to perform duties properly assigned which are consistent with the scope and nature of Optionee’s position; (B) Optionee’s commission of an act materially and demonstrably detrimental to the financial condition and/or goodwill of the Company or any of its Subsidiaries, which act constitutes gross negligence (as such term is construed in accordance with the laws of the State of Delaware) or willful misconduct in the performance of duties to the Company or any of its Subsidiaries; (C) Optionee’s commission of any theft, fraud, act of dishonesty or breach of trust resulting in or intended to result in material personal gain or enrichment of Optionee at the direct or indirect expense of the Company or any of its Subsidiaries; (D) Optionee’s conviction of, or plea of guilty or nolo contendere to, a felony (as such term is construed in accordance with the laws of the State of Delaware); or (E) Optionee’s material and willful violation of the Company’s written policies or of Optionee’s statutory or common law duty of loyalty to the Company or its affiliates that in either case is materially injurious to the Company or its Subsidiaries, monetarily or otherwise. No act or

2

failure to act will be considered “willful” (x) unless it is done, or omitted to be done, by Optionee in bad faith or without reasonable belief that Optionee’s action or omission was in the best interests of the Company or (y) if it is done, or omitted to be done, in reliance on the informed advice of the Company’s outside counsel or independent accountants or at the express direction of the Board.

(ii) Disability. For purpose of this Option, (i) “Disability” shall have the meaning assigned to such term in any written employment or similar agreement between the Company or any of its Subsidiaries and the Optionee in effect on the Grant Date or (ii) if the Optionee is not party to an employment or similar agreement in effect on the Grant Date and which defines “Disability,” then “Disability” shall mean Optionee’s absence from the Optionee’s duties with the Company on a full-time basis for at least 180 consecutive days as a result of the Optionee’s incapacity due to physical or mental illness, as determined by the Committee.

2.3. Method of Exercise. Subject to the limitations set forth in this Agreement, the Option, to the extent vested, may be exercised by Optionee (a) by delivering to the Company an exercise notice in the form prescribed by the Company specifying the number of whole Ordinary Shares to be purchased and by accompanying such notice with payment therefor in full (or by arranging for such payment to the Company’s satisfaction) either (i) in cash, (ii) by delivery to the Company (either actual delivery or by attestation procedures established by the Company) of Ordinary Shares having an aggregate Fair Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable pursuant to the Option by reason of such exercise, (iii) by authorizing the Company to withhold whole Ordinary Shares which would otherwise be delivered having an aggregate Fair Market Value, determined as of the date of exercise, equal to the amount necessary to satisfy such obligation, (iv) except as may be prohibited by applicable law, in cash by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (v) by a combination of (i), (ii) and (iii) and (b) by executing such documents as the Company may reasonably request. No Ordinary Share or certificate representing an Ordinary Share shall be issued or delivered until the full purchase price therefor and any withholding taxes thereon, as described in Section 5.1, have been paid.

2.4. Termination of Option. In no event may the Option be exercised after it terminates as set forth in this Section 2.4. The Option shall terminate, to the extent not earlier terminated pursuant to Section 2.2 or exercised pursuant to Section 2.3, on the Expiration Date. Upon the termination of the Option, the Option and all rights hereunder shall immediately become null and void.

3. Transfer Restrictions and Investment Representations.

3.1. Nontransferability of Option. The Option may not be transferred by Optionee other than by will or the laws of descent and distribution or pursuant to the designation of one or more beneficiaries on the form prescribed by the Company. Except to the extent permitted by the foregoing sentence, (i) during Optionee’s lifetime the Option is exercisable only by Optionee or Optionee’s legal representative, guardian or similar person and (ii) the Option may not be sold, transferred, assigned, pledged, charged, hypothecated, encumbered or otherwise

3

disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, charge, hypothecate, encumber or otherwise dispose of the Option, the Option and all rights hereunder shall immediately become null and void.

3.2. Investment Representation. Optionee hereby represents and covenants that (a) any Ordinary Shares purchased upon exercise of the Option will be purchased for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such purchase has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, Optionee shall submit a written statement, in a form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of any purchase of any shares hereunder or (y) is true and correct as of the date of any sale of any such shares, as applicable. As a further condition precedent to any exercise of the Option, Optionee shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Board or the Committee shall in its sole discretion deem necessary or advisable.

4. Additional Terms and Conditions.

4.1. Withholding Taxes.

(a) As a condition precedent to the issuance of Ordinary Shares following the exercise of the Option, Optionee shall, upon request by the Company, pay to the Company in addition to the purchase price of the shares, such amount as the Company determines is required, under all applicable federal, state, local or other laws or regulations, to be withheld and paid over as income or other withholding taxes (the “Required Tax Payments”) with respect to such exercise of the Option. If Optionee shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to Optionee.

(b) Optionee may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (i) a cash payment to the Company; (ii) delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole Ordinary Shares having an aggregate Fair Market Value, determined as of the date on which such withholding obligation arises (the “Tax Date”), equal to the Required Tax Payments; (iii) authorizing the Company to withhold whole Ordinary Shares which would otherwise be delivered to Optionee upon exercise of the Option having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments; (iv) except as may be prohibited by applicable law, a cash payment by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (v) any combination of (i), (ii) and (iii). Ordinary Shares to be delivered or withheld may not have a Fair Market Value in excess of the minimum amount of the Required Tax Payments (or

4

such higher amount as elected by the Optionee and which does not raise adverse accounting consequences). Any fraction of an Ordinary Share that would be required to satisfy such an obligation shall be disregarded, and the remaining amount due shall be paid in cash by the holder. No Ordinary Share or certificate representing an Ordinary Share shall be issued or delivered until the Required Tax Payments have been satisfied in full.

4.2. Adjustment. In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock Compensation) that causes the per Ordinary Share value to change, such as a share dividend, share split, spinoff, rights offering or recapitalization through an extraordinary dividend, the number and class of securities subject to the Option and the Exercise Price shall be equitably adjusted by the Committee, such adjustment to be made in accordance with Section 409A of the Code. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee (or, if the Company is not the surviving corporation in any such transaction, the board of directors of the surviving corporation) to prevent dilution or enlargement of rights of participants. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

4.3. Compliance with Applicable Law. The Option is subject to the condition that if the listing, registration or qualification of the shares subject to the Option upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the purchase or issuance of shares hereunder, the Option may not be exercised, in whole or in part, and such shares may not be issued, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

4.4. Issuance or Delivery of Shares. Upon the exercise of the Option, in whole or in part, the Company shall issue or deliver, subject to the conditions of this Agreement, the number of Ordinary Shares purchased against full payment therefor. Such issuance shall be evidenced by the appropriate entry on the register of members of the Company or of a duly authorized transfer agent of the Company. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such issuance, except as otherwise provided in Section 5.1.

4.5. Option Confers No Rights as Shareholder. Optionee shall not be entitled to any privileges of ownership with respect to Ordinary Shares subject to the Option unless and until such shares are purchased and issued upon the exercise of the Option, in whole or in part, and Optionee becomes a shareholder of record with respect to such issued shares. Optionee shall not be considered a shareholder of the Company with respect to any such shares not so purchased and issued.

5

4.6. Option Confers No Rights to Continued Employment. In no event shall the granting of the Option or its acceptance by Optionee, or any provision of this Agreement or the Plan, give or be deemed to give Optionee any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.

4.7. Decisions of Board or Committee. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Option or its exercise. Any interpretation, determination or other action made or taken by the Board or the Committee regarding the Plan or this Agreement shall be final, binding and conclusive.

4.8. Successors. This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of Optionee, acquire any rights hereunder in accordance with this Agreement or the Plan.

4.9. Notices. All notices, requests or other communications provided for in this Agreement shall be made, if to the Company, to Cambium Networks Corporation, Attn: Share Administration, 3800 Golf Rd Ste 360, Rolling Meadows, IL 60008, and if to Optionee, to the last known mailing address of Optionee contained in the records of the Company.

4.10. Governing Law. This Agreement, the Option and all determinations made and actions taken pursuant hereto and thereto shall be governed by the laws of the Cayman Islands and construed in accordance therewith without giving effect to principles of conflicts of laws.

4.11. Agreement Subject to the Plan. This Agreement is subject to the provisions of the Plan and shall be interpreted in accordance therewith.

4.12. Entire Agreement. This Agreement and the Plan constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and the Optionee.

6

4.13. Partial Invalidity. The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions hereof and this Agreement shall be construed in all respects as if such invalid or unenforceable provisions were omitted.

The portion of the Option that does not become vested under this Section 2.2(a) shall be immediately forfeited by the Optionee and cancelled by the Company. For purpose of this Option, “Disability” shall mean Optionee’s absence from the Optionee’s duties with the Company on a full-time basis for at least 180 consecutive days as a result of the Optionee’s incapacity due to physical or mental illness, as determined by the Committee.

(b) Termination other than due to Death or Disability. Subject to Section 2.2(c) and except as set forth in any other agreement between the Company and the Optionee, if Optionee’s service with the Company terminates prior to the end of the Vesting Period for any reason other than death or Disability, the Option, only to the extent vested on the effective date of such termination of service, may thereafter be exercised by Optionee until and including the earlier to occur of (i) the date which is ninety (90) days after the date of such termination of service and (ii) the Expiration Date.

(c) Change in Control.

(i) In the event of a Change in Control prior to the end of the Vesting Period pursuant to which the Option is not effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the intrinsic value and other material terms and conditions of the outstanding Option as in effect immediately prior to the Change in Control and in accordance with Section 409A of the Code), the Option shall be 100% vested immediately prior to such Change in Control and the Optionee shall receive in full settlement for such Option a cash payment in an amount equal to the aggregate number of Ordinary Shares then subject to the Option multiplied by the excess, if any, of the Fair Market Value of an Ordinary Share as of the date of the Change in Control, over the Exercise Price.

(ii) In the event of a Change in Control prior to the end of the Vesting Period pursuant to which the Option is effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the intrinsic value and other material terms and conditions of the outstanding Option as in effect immediately prior to the Change in Control and in accordance with Section 409A of the Code) and the Optionee’s service on the Board terminates within 24 months following such Change in Control, the Option shall be 100% vested upon such termination of service, and the Option may thereafter be exercised by Optionee until and including the earlier to occur of (i) the date which is one year after the date of termination of service and (ii) the Expiration Date.

2.3. Method of Exercise. Subject to the limitations set forth in this Agreement, the Option, to the extent vested, may be exercised by Optionee (a) by delivering to the Company an exercise notice in the form prescribed by the Company specifying the number of whole Ordinary Shares to be purchased and by accompanying such notice with payment therefor in full (or by arranging for such payment to the Company’s satisfaction) either (i) in cash, (ii) by delivery to the Company (either actual delivery or by attestation procedures established by the Company) of Ordinary Shares having an aggregate Fair Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable pursuant to the Option by reason of such exercise, (iii) by authorizing the Company to withhold whole Ordinary Shares which would

2

otherwise be delivered having an aggregate Fair Market Value, determined as of the date of exercise, equal to the amount necessary to satisfy such obligation, (iv) except as may be prohibited by applicable law, in cash by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (v) by a combination of (i), (ii) and (iii) and (b) by executing such documents as the Company may reasonably request. No Ordinary Share or certificate representing an Ordinary Share shall be issued or delivered until the full purchase price therefor has been paid.

2.4. Termination of Option. In no event may the Option be exercised after it terminates as set forth in this Section 2.4. The Option shall terminate, to the extent not earlier terminated pursuant to Section 2.2 or exercised pursuant to Section 2.3, on the Expiration Date. Upon the termination of the Option, the Option and all rights hereunder shall immediately become null and void.

3. Transfer Restrictions and Investment Representations.

3.1. Nontransferability of Option. The Option may not be transferred by Optionee other than by will or the laws of descent and distribution or pursuant to the designation of one or more beneficiaries on the form prescribed by the Company. Except to the extent permitted by the foregoing sentence, (i) during Optionee’s lifetime the Option is exercisable only by Optionee or Optionee’s legal representative, guardian or similar person and (ii) the Option may not be sold, transferred, assigned, pledged, charged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, charge, hypothecate, encumber or otherwise dispose of the Option, the Option and all rights hereunder shall immediately become null and void.

3.2. Investment Representation. Optionee hereby represents and covenants that (a) any Ordinary Shares purchased upon exercise of the Option will be purchased for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such purchase has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, Optionee shall submit a written statement, in a form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of any purchase of any shares hereunder or (y) is true and correct as of the date of any sale of any such shares, as applicable. As a further condition precedent to any exercise of the Option, Optionee shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Board or the Committee shall in its sole discretion deem necessary or advisable.
