Ladies and Gentlemen:

DZS Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule C hereto (the “Underwriters”) pursuant to this Underwriting Agreement (this “Agreement”) an aggregate of 4,000,000 shares (the “Firm Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”). In addition, the Company proposes to grant to the Underwriters the option to purchase from the Company up to an additional 600,000 shares of Common Stock to be purchased at the option of the Underwriters (the “Option Shares” and, together with the Firm Shares, the “Shares”). The Shares are described in the Prospectus (as defined below). Stifel, Nicolaus & Company, Incorporated and Needham & Company, LLC are acting as representatives of the Underwriters and in such capacity are hereinafter referred to as the “Representatives.”

SECTION 1. Sale and Purchase.

On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell the Firm Shares to the Underwriters, and the Underwriters agree to purchase from the Company the Firm Shares as set forth opposite the names of such Underwriters on Schedule C hereto. The Company has been advised by the Underwriters that they propose to make a public offering of the Shares as soon after this Agreement has become effective as in their judgment is advisable. The pricing terms of the purchase of the Firm Shares by the Underwriters and the pricing terms of the offering of the Firm Shares to the public are as set forth in Schedule A hereto.

In addition, the Company hereby grants to the Underwriters the option to purchase, and upon the basis of the representations, warranties and agreements contained herein and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase from the Company, all or a portion of the Option Shares, at the same purchase price per share to be paid by the Underwriters to the Company for the Firm Shares as set forth opposite the names of such Underwriters on Schedule C hereto. This option may be exercised by the Underwriters any time and from time to time on or before the thirtieth (30th) day following the date hereof, by written notice from the Representatives to the Company, which notice may be electronic (“Option Shares Notice”). The Option Shares Notice shall set forth the aggregate number of Option Shares as to which the option is being exercised, and the date and time when the Option Shares are to be delivered (such date and time being herein referred to as the “Option Closing Date”); provided, however, that the Option Closing Date may be the same date and time as the Closing Date (as defined below), but shall not be earlier than the Closing Date nor earlier than the second (2nd) business day after the date on which the option for Option Shares shall have been exercised nor later than the tenth (10th) business day after the date of the Option Shares Notice. As of the Option Closing Date, the Company will issue and sell to the Underwriters, and the Underwriters will purchase, the number of Option Shares set forth in the Option Shares Notice.

SECTION 2. Payment and Delivery.

Payment of the purchase price for the Firm Shares shall be made to the Company by same day Federal Funds wire transfer against delivery of the Firm Shares to the Underwriters through the facilities of The Depository Trust Company for the account of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York time, on January 29, 2021 (the “Closing Date”) (unless another time or date shall be agreed to by the Representatives and the Company). Electronic transfer of the Firm Shares shall be made to or as instructed by the Representatives at the Closing Date in such names and in such denominations as the Representatives shall specify.

If the option for Option Shares is exercised, payment of the purchase price for the Option Shares shall be made at the Option Closing Date in the same manner and at the same office as the payment for the Firm Shares. Electronic transfer of the Option Shares shall be made to or as instructed by the Representatives at the Option Closing Date in such names and in such denominations as the Representatives shall specify.

Deliveries of the documents described in Section 6 with respect to the purchase of the Shares shall be made at the offices of Goodwin Procter LLP, counsel for the Underwriters, at 10:00 A.M., New York time, on the Closing Date or Option Closing Date, as applicable.

SECTION 3. Representations and Warranties.

(a)Representations and Warranties by the Company. The Company represents and warrants to the Underwriters as of the Applicable Time (as defined below), the Closing Date and any Option Closing Date, and agrees with the Underwriters, as follows:

(i)Registration Statement and Prospectuses. The Company has prepared and filed with the Securities and Exchange Commission (“Commission”) a shelf registration

statement on Form S-3 (File No. 333-230476) under the Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulation (the “1933 Act Regulations”) of the Commission thereunder, which shelf registration statement was declared effective by the Commission and the Shares have been and remain eligible for registration by the Company on such registration statement. Such registration statement, including all amendments and exhibits thereto, the documents incorporated by reference therein and the documents and information otherwise deemed to be part thereof or included therein pursuant to Rule 430B of the 1933 Act Regulations is referred to as the “Registration Statement.”

Each of the Registration Statement and any post-effective amendment thereto has become effective under the 1933 Act. No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued under the 1933 Act, no order preventing or suspending the use of any preliminary prospectus (as defined below) or the Prospectus has been issued and no proceedings for any of those purposes have been instituted or are pending or, to the Company’s actual knowledge, threatened. The Company has complied to the Commission’s satisfaction with each request (if any) from the Commission for additional information.

Each of the Registration Statement and any post-effective amendment thereto, excluding exhibits thereto, at the time of its effectiveness and at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) under the 1933 Act Regulations, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations. Each preliminary prospectus and the Prospectus, at the time it was filed, complied in all material respects with the 1933 Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was virtually identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act is called the “462(b) Registration Statement” and, from and after the date and time of filing of the Rule 462(b) Registration Statement, the term “Registration Statement” shall include the Rule 462(b) Registration Statement.

The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, when they became effective or at the time they were filed with the Commission, complied in all material respects with the requirements of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and the rules and regulations promulgated thereunder (collectively, the “1934 Act Regulations”).

(ii)Accurate Disclosure; Certain Defined Terms. Neither the Registration Statement nor any amendment thereto, at its effective time, at the Closing Date or any Option Closing Date, contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, neither (A) the General Disclosure Package nor (B) any individual Issuer Free Writing Prospectus, when considered together with the General Disclosure Package, included an untrue statement of a material fact or omitted to state a material fact necessary in order to

make the statements therein, in the light of the circumstances under which they were made, not misleading. Neither the Prospectus nor any amendment or supplement thereto (including any prospectus wrapper), as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b), at the Closing Date or at any Option Closing Date, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any amendment thereto), the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) made in reliance upon and in conformity with written information furnished to the Company by the Underwriters expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the list of Underwriters and their respective underwriting allotments and information in the “Commissions and Discounts,” “Stabilization,” and “Passive Market Making” sections under the heading “Underwriting” in the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) (collectively, the “Underwriter Information”) as such statements relate to the Underwriters.

paid, except for such taxes as are being contested in good faith by appropriate proceedings and as to which adequate reserves have been established by the Company and its subsidiaries or except where the failure to pay such taxes would not have a Material Adverse Effect.

(d)Delivery of Prospectuses. The Company has delivered to the Underwriters, without charge, as many copies of each preliminary prospectus as the Underwriters reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to the Underwriters, without charge, during the period when a prospectus relating to the Shares is (or, but for the exception afforded by Rule 172, would be) required to be delivered under the 1933 Act, such number of copies of the Prospectus (as amended or supplemented) as the Underwriters may reasonably request.

(e)Blue Sky Qualifications. The Company will take such actions as the Representatives may reasonably request to qualify the Shares for offering and sale under the securities or Blue Sky laws of such jurisdictions (domestic or foreign) as the Representatives may designate and to continue such qualifications in effect, and will comply with such laws, for so long as required to permit the offer and sale of Shares in such jurisdictions; provided that the Company and its subsidiaries shall not be obligated to (i) qualify as foreign corporations or other entities or as dealers in securities in any jurisdiction in which they would not otherwise be required to so qualify, (ii) to file a general consent to service of process in any jurisdiction or (iii) subject themselves to taxation in any such jurisdiction if they are not otherwise so subject.

(j)Issuer Free Writing Prospectuses. The Company agrees that, unless it obtains the prior written consent of the Representatives and subject to the requirements of the 1934 Act and the 1934 Act Regulations, it will not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the Representatives will be deemed to have consented to the Issuer Free Writing Prospectuses listed on Schedule B hereto, if any, and any “road show that is a written communication” within the meaning of Rule 433(d)(8)(i) that has been reviewed by the Representatives. The Company represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Representatives as an “issuer free writing prospectus,” as defined in Rule 433, and that it has complied and will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping.

(k)Communications Prior to Closing. Between the Applicable Time and the Closing Date, the Company will not issue any press release or other communication directly or indirectly or hold any press conference with respect to the Company, its condition, financial or otherwise, or earnings, business affairs or business prospects (except for routine oral marketing communications in the ordinary course of business and consistent with the past practices of the Company and of which the Representative is notified), without the prior written consent of the Representative, unless in the judgment of the Company and its counsel, and after notification to the Representative, such press release or communication is required by law or applicable stock exchange rules.

(l)Company Lock-Up. For a period commencing on the date hereof and ending on the 90th day after the date of this Agreement (the “Lock-Up Period”), the Company agrees not to,

directly or indirectly, without the prior written consent of the Representatives, (1) offer for sale, sell, pledge or otherwise dispose of (or enter into any transaction or device that is designed to, or would be reasonably expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock or securities convertible into or exchangeable for Common Stock or sell or grant options, rights or warrants with respect to any shares of Common Stock or securities convertible into or exchangeable for Common Stock, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) file or cause to be filed a registration statement, including any amendments, with respect to the registration under the Securities Act for the offer and sale by the Company of any shares of Common Stock or securities convertible, exercisable or exchangeable into Common Stock or any other securities of the Company or (4) publicly disclose the intention to do any of the foregoing. The restrictions contained in the preceding sentence shall not apply to any one or more of the following: (A) the Shares to be sold hereunder and any post-effective amendments to the Registration Statement filed consistent with the terms of this Agreement, (B) the issuance of shares of Common Stock, restricted stock units, options to purchase Common Stock or units pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans in effect on the date of this Agreement or pursuant to currently outstanding restricted stock units, options, warrants or rights, (C) the filing of any registration statement on Form S-8 in respect of any employee benefit plan, qualified stock option plan or other employee compensation plan in effect on the date hereof and described in the Prospectus, and (D) shares of Common Stock to be issued to one or more counterparties in connection with the consummation of a strategic partnership, joint venture, collaboration, merger, co-promotion or distribution arrangement, or the acquisition or in-licensing of any business products or technologies; provided, that the aggregate number of shares of Common Stock issued under this Subsection (D) shall not exceed 5% of the number of shares of Common Stock of the Company outstanding as of the date hereof; and provided further, that prior to such issuance, each recipient of such shares under this subsection (D) shall execute and deliver to the Representatives a Lock-Up Agreement (as defined below) substantially in the form of Exhibit A hereto.

The Company agrees to cause each officer and director of the Company set forth on Schedule D hereto to furnish to the Underwriters, prior to the Closing Date, a letter or letters, substantially in the form of Exhibit A hereto (the “Lock-Up Agreements”). The Company will enforce the terms of each Lock-Up Agreement and issue stop-transfer instructions to the transfer agent for the Common Stock with respect to any transaction or contemplated transaction that would constitute a breach of or default under the applicable Lock-Up Agreement.

(a)Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates and each of its and their respective directors, officers, members, employees, representatives and agents and their respective affiliates (as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”)), its selling agents and each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i)against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of or based on any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact

necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and

(ii)against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(b)Indemnification of Company, Directors and Officers. The Underwriters agree to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c)Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. 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 therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, if any, to assume the defense thereof, with counsel selected in accordance with the next sentence, and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such

indemnified party under this Section 7 for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation; provided, however, the indemnifying party shall not, under any of the circumstances described in clauses (i), (ii), (iii) and (iv) below, have the right to assume or direct the defense thereof and shall be liable to such indemnified party under this Section 7 for any legal expenses of other counsel or any other expenses in connection with the defense thereof if, in the reasonable judgment of the indemnified party (i) the use of the counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) representation of the indemnified party by such counsel would be inappropriate due to differing interests between the indemnifying party and any indemnified party, (iii) there are likely to be defenses available to the indemnified party that are different from, or in addition to, the defenses available to the indemnifying party, or (iv) the indemnifying party fails to use reasonable diligence in defending against such action. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties (which consent shall not be unreasonable withheld), settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement or shall not have disputed in good faith the indemnified party’s entitlement to such reimbursement.

SECTION 8. Contribution. To the extent the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each

indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Shares as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriters have otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the number of Firm Shares set forth opposite their respective names in Schedule C hereto and not joint.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and the Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

SECTION 9.Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriters or their Affiliates or selling agents, any person controlling the Underwriter, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Shares.

SECTION 10.Termination of Agreement.

(a)Termination. The Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Date (or, in the case of an Option Closing Date that is subsequent to the Closing Date for the Firm Shares) (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings or business affairs of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Shares, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof involving the United States or other material calamity or crisis or any material adverse change or development involving a prospective material adverse change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the reasonable good faith judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Shares, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or The Nasdaq Capital Market where trading has not been suspended or materially limited as described in the immediately following clause, or (iv) if trading generally on The New York Stock Exchange or The Nasdaq Stock Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.

(b)Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof, and provided further that Sections 1, 7, 8, 9, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 11.Default by the Company. If the Company shall fail at the Closing Date (or, in the case of an Option Closing Date that is subsequent to the Closing Date for the Firm Shares) to sell the number of Shares that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any non-defaulting party; provided, however, that the provisions of Sections 1, 5, 7, 8, 9, 15 and 16 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

SECTION 12.Default by the Underwriters. If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule C bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 12 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Option Shares and the aggregate number of Option Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Option Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Option Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Option Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

SECTION 13.Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Representatives shall be directed to Stifel, Nicolaus & Company, Incorporated, One Montgomery Street, Suite 3700, San Francisco, California 94104, attention of General Counsel, and to Needham & Company, LLC, 250 Park Avenue, 10th Floor, New York, New York 10177, attention of General Counsel, and a copy to Goodwin Procter LLP, The New York Times Building, 620 Eighth Avenue, New York, New York 10018, attention of Thomas S. Levato, Esq.; notices to the Company shall be directed to it at DZS Inc., 5700 Tennyson Parkway, Suite 400, Plano, Texas 75024, attention of Legal Dept., with a copy to Baker Botts L.L.P., 2001 Ross Avenue, Dallas, Texas 75201, attention of Preston Bernhisel, Esq.

SECTION 14.No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the public offering price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters, on the other hand, (b) in connection with the offering of the Shares and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its subsidiaries, or its respective stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Shares or the process leading thereto (irrespective of whether the Underwriters has advised or is currently advising the Company or any of its subsidiaries on other matters) and the Underwriters have no obligation to the Company with respect to the offering of the Shares except the obligations expressly set forth in this Agreement, (d) each Underwriter and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Shares and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 15.Parties. This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Shares from the Underwriters shall be deemed to be a successor by reason merely of such purchase.

SECTION 16.Trial by Jury. Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 17.GOVERNING LAW. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

SECTION 18.TIME. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 19.Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

SECTION 20.Research Analyst Independence. The Company acknowledges that each Underwriter’s research analysts and research departments are required to be independent from its investment banking division and are subject to certain regulations and internal policies, and that such Underwriter’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the sale of Shares that differ from the views of their investment banking division. The Company acknowledges that each Underwriter is a full service securities firm and as such from time to time, subject to applicable securities laws, rules and regulations, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Company; provided, however, that nothing in this Section 20 shall relieve any Underwriter of any responsibility or liability it may otherwise bear in connection with activities in violation of applicable securities laws, rules or regulation.

SECTION 21.Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

SECTION 22.Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

SECTION 23.Recognition of the U.S. Special Resolution Regimes.

(a)In the event that any Underwriter is a Covered Entity and becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b)In the event that any Underwriter is a Covered Entity or a BHC Act Affiliate of such Underwriter and becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section 23:

“BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

“Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §382.2(b).

“Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.

“U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts will become a binding agreement between the Underwriters and the Company in accordance with its terms.

Very truly yours,

DZS INC.

Ladies and Gentlemen:

This letter agreement is delivered to you pursuant to the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and among DZS Inc., a Delaware corporation (the “Company”), and Stifel, Nicolaus & Company, Incorporated and Needham & Company, LLC (together, the “Representatives”), as representatives of the several underwriters identified therein (the “Underwriters”). Upon the terms and subject to the conditions of the Underwriting Agreement, the Underwriters intend to effect a public offering (the “Offering”) of shares of common stock, $0.001 par value per share, of the Company (the “Common Stock”), pursuant to the registration statement of the Company on Form S-3 (File No. 333-230476) (the “Registration Statement”). Capitalized terms used but not defined herein have the respective meanings assigned to such terms in the Underwriting Agreement.

As an inducement to the Underwriters to execute the Underwriting Agreement, the undersigned hereby acknowledges and agrees that the undersigned will not, without the prior written consent of the Representatives, (1) offer, sell, contract to sell, pledge, grant any option to purchase or otherwise dispose of (collectively, a “Disposition”) any Common Stock, options, warrants, performance units or other securities convertible into or exchangeable for Common Stock of the Company (the “Company Securities”) or any securities convertible into or exercisable or exchangeable for, or any rights to purchase or otherwise acquire, any Company Securities held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned (collectively, the “Lock-Up Shares”), pursuant to the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a period commencing on the date hereof and ending 90 days after the date of the Underwriting Agreement, inclusive (the “Lock-Up Period”), (2) during the Lock-Up Period, exercise or seek to exercise or effectuate in any manner any rights of any nature that the undersigned has or may have hereafter to require the Company to register under the Act the undersigned’s Disposition of any of the Lock-Up Shares held by the undersigned, (3) otherwise

participate as a selling securityholder in any manner in any registration of Lock-Up Shares effected by the Company under the Act, including under the Registration Statement, during the Lock-Up Period, or (4) engage in any hedging, collar (whether or not for any consideration) or other transaction that is designed to or reasonably expected to lead to or result in a Disposition of Lock-Up Shares during the Lock-Up Period, even if such Lock-Up Shares would be disposed of by someone other than such holder, and such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call option or reversal or cancellation thereof) with respect to any Lock-Up Shares or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from Lock-Up Shares.

Notwithstanding the agreement not to make any Disposition during the Lock-Up Period, the Underwriters have agreed that the foregoing restrictions shall not apply to:

(1)

any Disposition or transfer of Lock-Up Shares to a family member, trust, or entity in which more than fifty percent of the voting interests are owned by the undersigned or the undersigned’s immediate family members (as defined in General Instruction A.1(a)(5) to Form S-8 under the Act);

(2)

any bona fide gift;

(3)

any Disposition or transfer of Lock-Up Shares by will, intestate succession or by operation of law pursuant to a qualified domestic order or in connection with a divorce settlement;

(4)

the conversion or exchange of convertible or exchangeable Company Securities outstanding as of the date of this letter agreement, provided that any Company Securities acquired upon such conversion or exchange shall remain subject to this letter agreement;

(5)

the forfeiture or surrender to the Company of Lock-Up Shares for failure to achieve vesting requirements associated with such Lock-Up Shares;

(6)

Dispositions or forfeiture of Lock-Up Shares of the undersigned to the Company or the retention of Lock-Up Shares by the Company (A) to satisfy tax withholding obligations in connection with the exercise of options to purchase shares of Common Stock, the vesting of restricted stock units, performance shares or other stock-based awards, or the settlement of deferred stock units of the Company or (B) in payment of the exercise or purchase price with respect to the exercise of options to purchase shares of Common Stock, the vesting of restricted stock units, performance shares or other stock-based awards, or the settlement of deferred stock units of the Company; provided that any shares of Common Stock acquired upon such exercise, vesting or settlement shall remain subject to this letter agreement, and provided further, that if the undersigned is required to file a report under the Exchange Act related thereto, such report shall include a statement to the effect that the filing relates to the “net” or “cashless” exercise, vesting or settlement, including, if applicable, the payment of taxes due as a result of such exercise, vesting or settlement;

(7)

the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Lock-Up Shares, provided that (A) no sales or other dispositions of Lock-Up Shares may occur under such plan during the Lock-Up Period and (B) to the extent a public announcement or filing under the Exchange Act regarding the establishment of such plan shall be required or made during the Lock-Up Period, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Lock-Up Period; or

(8)

any Disposition or transfer of Lock-Up Shares pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the board of directors of the Company, made to all holders of the Company Securities involving a Change of Control (as defined below) (including any support or voting agreement entered into in connection therewith), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Lock-Up Shares of the undersigned shall remain subject to the restrictions contained in this letter agreement;

provided that in the case of any transfer, gift or other Disposition pursuant to the immediately preceding clauses (1), (2) or (3), except in the case of a bona fide gift to a charitable organization, the transferee, trustee, donee or other recipient agrees to be bound in writing by the terms of this letter agreement prior to such transfer and no filing by any party (donor, donee, transferor, transferee, trustee or other recipient) under the Exchange Act shall be required or shall be voluntarily made in connection with such transfer (other than required filings under Section 16(a) and Section 13(d) or 13(g) of the Exchange Act made after the expiration of the Lock-Up Period). For purposes of clause (8) above, “Change of Control” shall mean any bona fide third-party tender offer, merger, amalgamation, consolidation or other similar transaction the result of which would be 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 more than 50% of the total voting power of the voting stock of the Company.

Furthermore, the undersigned may, during the Lock-Up Period, sell shares of Common Stock purchased by the undersigned on the open market following the closing of the Offering if and only if (i) such sales are not required to be reported in any public report or filing under the Exchange Act and (ii) the undersigned does not otherwise voluntarily effect any public report or filing under the Exchange Act regarding such sales.

It is understood that, if the Underwriting Agreement does not become effective on or before February 26, 2021, or if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the shares of Common Stock to be purchased thereunder, the obligations under this letter agreement shall automatically terminate.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of Lock-Up Shares if such transfer would constitute a violation or breach of this letter agreement.

This letter agreement shall be binding on the undersigned and the respective successors, heirs, personal representatives and assigns of the undersigned.

Very truly yours,

By:
