Item 4.
PURPOSE OF TRANSACTION
 
The response to Item 6 of this Schedule 13D is incorporated by reference in its entirety into this Item 4.
 
Prior to the Company’s initial public offering of its Shares, which closed on June 28, 2019 (the “IPO”), VCH held 100% of the Company’s equity.  Towards that end, in 2011, VCH initially invested $62.5 million in convertible preferred equity certificates (“CPECs”) issued by one of the Company’s wholly-owned subsidiaries, using working capital.  On July 31, 2017, in connection with the dissolution of the subsidiary, the CPECs were redeemed for $88.4 million, which VCH simultaneously contributed to the Company.  On December 21, 2017, the Company made a cash return of contributed capital to VCH in the amount of $65.5 million.
 
In connection with the IPO, the Company effected a recapitalization and return of capital to VCH pursuant to which the Company increased its authorized and outstanding Shares held by VCH.  Specifically, upon consummation of the IPO, VCH received 17,627,575 Shares  representing the amount of unreturned capital and accumulated yield payable to holders of Class A Units of VCH, plus the residual share of the Company’s value attributable to VCH's ownership after such return, based on the IPO price of $12.  In addition, the Company plans to use $5.6 million of the net proceeds from its IPO to pay management fees to VCH and its affiliates.
 
In addition, the Reporting Persons purchased an aggregate of 1,500,000 Shares in the IPO.  Specifically, VC IV acquired 1,482,000 Shares in the IPO, and VEF III acquired 18,000 Shares in the IPO, each at the IPO price of $12 per Share.  Each of VC IV and VEF III used working capital to purchase Shares.
 
The Reporting Persons acquired the securities reported herein for investment purposes.  In their capacity as significant stockholders of the Company, the Reporting Persons intend to take an active role in working with the Company’s management and board of directors on operational, financial and strategic initiatives.  In addition, pursuant the Shareholder Agreement described in Item 6, the Reporting Persons have rights to name persons to the Company’s board of directors and one of the Reporting Persons, Mr. Slusky, serves on the Company’s board of directors.
 
Except as described in this Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D.  The Reporting Persons intend to review their investment in the Company on a continuing basis and have in the past and may in the future engage in discussions with management, the board of directors, other stockholders and other relevant parties concerning the business, operations, board composition, management, strategy and future plans of the Company.  Depending on various factors including, without limitation, the results of any such discussions, the Company’s financial position and business strategy, price levels of the Shares, conditions in the securities market and general economic and industry conditions, and subject to the agreements described in this Schedule 13D, the Reporting Persons may in the future take such actions with respect to their investment in the Company as they deem appropriate including, without limitation: purchasing additional shares or selling some or all of their Shares; engaging in any hedging or similar transactions with respect to the Shares; nominating representatives to the board of directors; taking positions or making proposals with respect to, or taking other actions to effect changes in the board composition, ownership structure, management, the charter documents, strategy, future plans and operations of the Company; encouraging the Company to pursue one or more strategic transactions, including transactions in which the Reporting Persons may participate; and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D.

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 of the Company or any securities convertible into or exercisable or exchangeable for shares, or publicly disclose the intention to make any offer, sale pledge or disposition;
 

enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Shares or such other securities, whether such transaction described in the bullet above or in this bullet is to be settled by delivery of Shares or such other securities, in cash or otherwise; or
 

make any demand for or exercise any right with respect to the registration of any Shares or any of our security convertible into or exercisable or exchangeable for Shares.

On June 28, 2019, each of VCH, the Company, Cambium Networks, Ltd. and the other loan parties party thereto entered into a Third Amendment to Amended and Restated Credit Agreement (the “Third Amendment”) with Silicon Valley Bank (“SVB”) as the Issuing Lender, the lenders party thereto and SVB as administrative agent for the Lenders. Among other things, the Third Amendment released VCH as a guarantor and loan party, and terminated the guaranty granted by VC IV.  The foregoing summary of the Third Amendment does not purport to be complete and is qualified it its entirety by reference to such agreement, which is filed as Exhibit D to this Schedule 13D and is incorporated by reference herein.
 
Director Stock Option Grants
 
Upon closing of the IPO on June 28, 2019, each of the Reporting Persons’ nominated directors, Mr. Slusky and Mr. Amen, received, for no consideration, an option to acquire 30,000 Shares at a strike price of $12 per Share.  Each option vests 25% on June 23, 2020, 75% in equal quarterly installments thereafter, and expires on June 23, 2029.  Each option was granted pursuant to the Director Stock Option Grant, the form of which is filed as Exhibit E to this Schedule 13D and is incorporated by reference herein.
 
Indemnification Agreements
 
Prior to the completion of the IPO, the Company entered into new indemnification agreements with all of the Company’s executive officers and directors (each, an “Indemnitee”), including Mr. Slusky and Mr. Amen.  Each indemnification agreement provides that the Company will indemnify the Indemnitee to the fullest extent permitted by law for claims arising in his or her capacity as a director or executive officer of the Company, as the case may be, provided that he or she have acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the Company’s best interests and, with respect to any criminal proceeding, had no reasonable cause to believe that their conduct was unlawful.  In the event that the Company does not assume the defense of a claim against an Indemnitee, the Company will be required to advance his or her expenses in connection with his or her defense, provided that he or she undertakes to repay all amounts advanced if it is ultimately determined that he or she is not entitled to be indemnified by the Company.   The foregoing summary of the Indemnification Agreement does not purport to be complete and is qualified it its entirety by reference to the form of such agreement, which is filed as Exhibit F to this Schedule 13D and is incorporated by reference herein.
 

Based on the transactions and relationships described herein, the Reporting Persons may be deemed to constitute a “group” for purposes of Section 13(d)(3) of the Exchange Act. The filing of this statement shall not be construed as an admission that the Reporting Persons are a group, or have agreed to act as a group.

Re: Cambium Networks Corporation --- Public Offering
 
Ladies and Gentlemen:
 
The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an underwriting agreement (the “Underwriting Agreement”) with Cambium Networks Corporation, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”) providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of the ordinary shares of the Company, par value $0.01 (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.
 
In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, the undersigned will not, during the period beginning on the date of this letter agreement (this “Letter Agreement”) and ending and including the date that is 180 days after the date of the final prospectus (the “Public Offering Date”) relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (1) 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 Ordinary Shares, $0.01 per share par value, of the Company (the “Ordinary Shares”) or any securities convertible into or exercisable or exchangeable for Ordinary Shares (including without limitation, Ordinary Shares or such other securities which may be deemed to

be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of an option or warrant), or publicly disclose the intention to make any offer, sale, pledge or disposition, (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Ordinary Shares or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Ordinary Shares or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any Ordinary Shares or any security convertible into or exercisable or exchangeable for Ordinary Shares, in each case other than:
 
(A)
the conversion of any convertible security into Ordinary Shares described in the Pricing Disclosure Package and the Prospectus, or issued pursuant to an equity plan described in the Pricing Disclosure Package and the Prospectus, it being understood that any Ordinary Shares received shall be subject to the restrictions on transfer set forth in this Letter Agreement;
 
(B)
the sale or transfer (i) to the Company of such number of Ordinary Shares necessary to generate only such amount of cash needed for the payment of taxes (including estimated taxes) due solely as a result of the settlement of securities described in clause (A), or (ii)  of such number of Ordinary Shares necessary (including transfers on the open market) to generate only such amount of cash needed for the payment of taxes (including estimated taxes) due solely as a result of the settlement of securities described in clause (A), provided that any such transfers described in this subclause (ii) may only take place with the prior written consent of the Company and if either (x) the undersigned is not an affiliate (as defined in Rule 144 under the Securities Act of 1933, as amended) of the Company and the Company has filed a registration statement on Form S-8 in respect of such Ordinary Shares to be sold or transferred, or (y) at least 90 days have elapsed since the Public Offering Date, and in all such cases described in subclauses (i) and (ii), provided that any remaining Ordinary Shares received upon such conversion or settlement will be subject to the restrictions on transfer set forth in this Letter Agreement;
 
(C)
transfers of Ordinary Shares as a bona fide gift or gifts, or pursuant to a negotiated divorce settlement;
 
(D)
transfers pursuant to a qualified domestic relations order;
 
(E)
if the undersigned is a corporation, limited liability company, partnership or other entity, distributions of Ordinary Shares or other securities to subsidiaries, limited or general partners, members, shareholders or affiliates of, or any investment fund or other entity that controls or manages, the undersigned;
 
(F)
transfers of Ordinary Shares or other securities to any immediate family member, trusts for the direct or indirect benefit of the undersigned or the immediate family members of the undersigned or any of their successors upon death, or any partnerships or limited liability company, the partners or members of which consist of or are for the direct or indirect benefit of the undersigned and/or immediate family members, (for purposes of this Letter Agreement, “immediate family” means any relationship by blood, marriage or adoption, not more remote than first cousin);
 
-2-


(G)
if the undersigned is a natural person, transfers of Ordinary Shares or other securities of the Company by will, other testamentary document or intestate succession to the legal representative, heir, beneficiary or a member of the immediate family of the undersigned in a transaction not involving a disposition for value;
 
(H)
any forfeiture, sale or other transfer to the Company of any Ordinary Shares or other securities in connection with the termination of the undersigned’s employment with or services to the Company, provided that no public announcement reporting a reduction in the beneficial ownership shall be voluntarily made, and any required announcement, including any announcement under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall clearly indicate the reason for such reduction; or
 
(I)
conversion of ordinary or preferred units of the Company into Ordinary Shares in connection with the consummation of the Public Offering, it being understood that any such Ordinary Shares received by the undersigned upon such conversion shall be subject to the restrictions on transfer set forth in this Letter Agreement;
 
provided that in the case of any transfer or distribution pursuant to clauses (C), (D), (E), (F) and (G), each donee, distributee, or transferee shall execute and deliver to the Representatives a lock-up letter in the form of this paragraph; provided, further, that in the case of any transfer or distribution pursuant to clauses (A) through (C), and (E) through (G), no filing by any party (donor, donee, transferor or transferee) under the Exchange Act, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the Restricted Period and any required Schedule 13G (or 13G/A)) referred to above); and provided, further, that in the case of any transfer or distribution pursuant to clauses (C), (E), (F) and (G), such transfer shall not involve a disposition for value. If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any Company-directed Securities the undersigned may purchase in the Public Offering.
 
The restrictions contained herein shall not apply to any transfers, sales, tenders or other dispositions of Ordinary Shares or any security convertible into or exercisable or exchangeable for Ordinary Shares pursuant to a bona fide third-party tender offer, merger, amalgamation, consolidation or other similar transaction that is approved by the board of directors of the Company made to or involving all holders of the Ordinary Shares or such other securities pursuant to a change of control of the ownership of the Company (including, without limitation, the entry into any lock-up, voting or similar agreement pursuant to which the undersigned may agree to transfer, sell, tender or otherwise dispose of Ordinary Shares or other such securities in favor of any such transaction); provided that if such tender offer, merger, amalgamation, consolidation or other similar transaction is not completed, any Ordinary Shares or any security convertible into or exercisable or exchangeable for Ordinary Shares subject to this Letter Agreement shall remain subject to the restrictions contained in this Letter Agreement. For purposes of this Letter Agreement, “change of control” shall mean the consummation of any bona fide third party tender offer, merger, amalgamation, consolidation or other similar transaction that is approved by the
-3-

board of directors of the Company the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, other than the Company, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of 60% of total voting power of the voting shares of the Company.
 
If the undersigned is an officer or director of the Company, (i) the Representatives on behalf of the Underwriters agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Ordinary Shares, the Representatives on behalf of the Underwriters will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver.  Any release or waiver granted by the Representatives on behalf of the Underwriters hereunder to any such officer or director shall only be effective two business days after the publication date of such press release.  The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.
 
In the event that either of the Representatives withdraws from or declines to participate in the Public Offering, all references to the Representatives contained in this Letter Agreement shall be deemed to refer to the sole Representative that continues to participate in the Public Offering (the “Sole Representative”), and, in such event, any written consent, waiver or notice given or delivered in connection with this Letter Agreement by the Sole Representative shall be deemed to be sufficient and effective for all purposes under this Letter Agreement.
 
In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.
 
The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.
 
The undersigned hereby agrees that, to the extent that the terms of this Letter Agreement conflict with or are in any way inconsistent with any registration rights agreement, any market standoff agreement or any other lock-up agreement related to the Securities to which the undersigned and the Company may be a party, this Letter Agreement supersedes such agreements.
 
The undersigned understands that, if (A) either the Company, on the one hand, or the Representatives on behalf of the Underwriters, on the other hand, notifies the other in writing, prior to the execution of the Underwriting Agreement, that they have determined not to proceed with the Public Offering, (B) the Underwriting Agreement does not become effective by September 31, 2019, (C) the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Ordinary Shares to be sold thereunder or (D) the registration statement filed with the Securities and Exchange Commission in connection with the Public Offering is withdrawn, the undersigned shall be released from all obligations under this Letter Agreement.  The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.
