 EXHIBIT 10.20 
 LOAN AND SECURITY AGREEMENT (EXIM FACILITY) 
 THIS LOAN AND SECURITY AGREEMENT (EXIM FACILITY)
(this “Agreement”), dated as of March 16, 2009 (the “Effective Date”), between, on the one hand, SILICON VALLEY BANK, a California corporation (“Bank”), and, on the other hand, ZTI Merger
Subsidiary III, Inc., a Delaware corporation formerly known as Zhone Technologies, Inc. (“ZMS-III”, and also a “Borrower”), and Zhone Technologies, Inc., a Delaware corporation formerly known as Tellium,
Inc. (“Zhone”, and also a “Borrower”) (individually and collectively, and jointly and severally, “Borrower”), provides the terms on which Bank shall lend to Borrower and Borrower shall repay Bank.

 The parties agree as follows: 
 A EXIM PROVISIONS 
 A.1 Exim Guaranty. Prior to the first Credit Extension hereunder, Borrower shall cause the
Export Import Bank of the United States (the “Exim Bank”) to guarantee the Credit Extensions made under this Agreement, pursuant to a Master Guarantee Agreement, Loan Authorization Agreement and (to the extent applicable) Delegated
Authority Letter Agreement or Fast Track Lender Agreement (collectively, the “Exim Guaranty”), and Borrower shall cause the Exim Guaranty to be in full force and effect throughout the term of this Agreement and so long as any Credit
Extensions hereunder are outstanding. If, for any reason, the Exim Guaranty shall cease to be in full force and effect, or if the Exim Bank declares in writing the Exim Guaranty void or revokes in writing any obligations thereunder or denies in
writing liability thereunder, or if Borrower takes or permits any action that could reasonably be expected to cause the Exim Guarantee to not be in full force and effect, any such event shall constitute an Event of Default under this Agreement.
Nothing in any confidentiality agreement in this Agreement or in any other agreement shall restrict Bank’s right to make disclosures and provide information to the Exim Bank in connection with the Exim Guaranty. Bank shall have the right to
take all actions required or authorized in the Exim Guaranty. 
 A.2 Exim Borrower Agreement; Costs. Borrower shall, promptly upon
Bank’s request from time to time (including concurrently herewith), execute and deliver a Borrower Agreement, in the form specified by the Exim Bank, in favor of Bank and the Exim Bank, together with any amendments thereto which are required by
the Exim Bank (as so amended, the “Exim Borrower Agreement”). This Agreement is subject to all of the terms and conditions of the Exim Borrower Agreement, all of which are hereby incorporated herein by this reference. Borrower expressly
agrees to perform all of the obligations and comply with all of the affirmative and negative covenants and all other terms and conditions set forth in the Exim Borrower Agreement, as though the same were expressly set forth herein. In the event of
any conflict between the terms of the Exim Borrower Agreement and the other terms of this Agreement or the Non-Exim Loan Agreement, whichever terms are more restrictive shall apply. Borrower acknowledges and agrees that it has received a copy of the
Loan Authorization Agreement which is referred to in the Exim Borrower Agreement. Borrower agrees to be bound by the terms of the Loan Authorization Agreement, including, without limitation, by any additions or revisions made prior to its execution
on behalf of Exim Bank. Upon the execution of the Loan Authorization Agreement by Exim Bank and Bank, it shall become an attachment to the Exim Borrower Agreement. Borrower shall reimburse Bank for all fees and all out of pocket costs and expenses
incurred by Bank with respect to the Exim Guaranty and the Exim Borrower Agreement, including without limitation all facility fees and usage fees, and Bank is authorized to debit Borrower’s account with Bank for such fees, costs and expenses
when paid by Bank. 
 A.3 Non-Exim Loan Agreement; Cross-Collateralization; Cross-Default. Concurrently herewith, Bank and the
Borrower are entering into that certain other Second Amended and Restated Loan and Security Agreement, dated as of the Effective Date (as amended, restated, supplemented, or otherwise modified from time to time, the “Non-Exim Loan
Agreement”). Both this Agreement and the Non-Exim Loan Agreement shall continue in full force and effect, and all rights and remedies under this Agreement and the Non-Exim Loan Agreement are cumulative. The term “Obligations” as used
in this Agreement and in the Non-Exim Loan Agreement shall include without limitation the obligation to pay when due all Credit Extensions made pursuant to this Agreement (including all outstanding Letters of Credit (including drawn but unreimbursed
Letters of Credit), the FX Reserve, and amounts 

  

 1 

 
used for Cash Management Services, under this Agreement) (collectively, the “Exim Loans”) and all interest thereon and the obligation to pay when
due all “Credit Extensions” under (and as such term is defined in) the Non-Exim Loan Agreement (including all outstanding “Letters of Credit” (including drawn but unreimbursed “Letters of Credit”), the “FX
Reserve”, and amounts used for “Cash Management Services”, under (and as such terms are defined in) the Non-Exim Loan Agreement) (collectively, the “Non-Exim Loans”) and all interest thereon. Without limiting the generality
of the foregoing, all “Collateral” as defined in this Agreement and as defined in the Non-Exim Loan Agreement shall secure all Exim Loans and all Non-Exim Loans, and all other Obligations. Any Event of Default under this Agreement shall
also constitute an Event of Default under the Non-Exim Loan Agreement, and any Event of Default under the Non-Exim Loan Agreement shall also constitute an Event of Default under this Agreement. In the event Bank assigns its rights under this
Agreement and/or under any note evidencing Exim Loans and/or its rights under the Non-Exim Loan Agreement and/or under any note evidencing Non-Exim Loans, to any third party, including without limitation the Exim Bank, whether before or after the
occurrence of any Event of Default, Bank shall have the right (but not any obligation), in its sole discretion, to allocate and apportion Collateral to this Agreement, the Non-Exim Loan Agreement, and/or any note(s) assigned and to specify the
priorities of the respective security interests in such Collateral between itself and the assignee, all without consent of the Borrower. 
 A.4 Exim Insurance. If required by Bank, Borrower will obtain, and pay when due all premiums with respect to, and maintain, uninterrupted foreign credit insurance. In addition, Borrower will execute in favor of Bank an assignment of
proceeds of any insurance policy obtained by Borrower and issued by Exim Bank insuring against comprehensive commercial and political risk (the “Exim Bank Insurance Policy”). The insurance proceeds from the Exim Bank Insurance Policy
assigned or paid to Bank will be applied to the balance outstanding under this Agreement. Borrower will immediately notify Bank and Exim Bank in writing upon submission of any claim under the Exim Bank Insurance Policy, and thereafter Bank will not
be obligated to make any further Credit Extensions hereunder to Borrower without prior approval from Exim Bank. 
 1 ACCOUNTING AND
OTHER TERMS 
 Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must
be made following GAAP. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the
Code to the extent such terms are defined therein. 
 2 LOAN AND TERMS OF PAYMENT 
 2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding principal amount of all Credit Extensions, and all
accrued and unpaid interest thereon, as and when due in accordance with this Agreement. 
 2.1.1 Revolving Advances. 
 (a) Availability. Subject to the terms and conditions of this Agreement and subject to deduction of Reserves, Bank shall make
Advances not exceeding the Availability Amount; provided, however, that the sum of all outstanding Advances (including (i) amounts used hereunder for Cash Management Services, (ii) the aggregate face amount of outstanding
Letters of Credit (including drawn but unreimbursed Letters of Credit) under this Agreement, plus any Letter of Credit Reserve under this Agreement, and (iii) the FX Reduction Amount hereunder) under this Agreement, plus all outstanding
Non-Exim Loans under the Non-Exim Loan Agreement, shall not exceed at any time the Maximum Combined Amount. 
 Amounts borrowed pursuant to this Section may
be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. Advances and other Credit Extensions will be made to each Borrower based on the Eligible Accounts of such
Borrower, subject to the Maximum Revolver Amount for all Advances and other Credit Extensions hereunder to all Borrowers combined, and subject to the Maximum Combined Amount for all Non-Exim Loans and Exim Loans to all Borrowers combined.

 (b) Allocation of Credit Extensions and Reserves as Between this Agreement and the Non-Exim Loan Agreement. Subject
at all times to Section 5.10 of this Agreement and Section 5.10 of the Non-Exim Loan Agreement (with respect to permitted purposes of Exim Loans and Non-Exim Loans), Bank and Borrower 

  

 2 

 
hereby acknowledge and agree that, if and to the extent that there is both sufficient borrowing availability in accordance with the terms and conditions of
this Agreement and sufficient borrowing availability in accordance with the terms and conditions of the Non-Exim Loan Agreement, Bank shall have the right (but not the obligation) to require that Advances and other Credit Extensions will be made,
and deemed outstanding, first under this Agreement to the extent of borrowing availability under this Agreement, before being made, and deemed outstanding, under the Non-Exim Loan Agreement. Without limiting the generality of the foregoing, Bank
shall have the right (but not the obligation) to allocate any Reserves (other than reserves in respect of specific Credit Extensions under this Agreement, specific “Credit Extensions” under the Non-Exim Loan Agreement, or specific
Accounts) first against borrowing availability under this Agreement before being allocated against borrowing availability under the Non-Exim Loan Agreement. 
 (c) Termination of Revolving Line; Repayment. Bank’s obligation under this Agreement to provide Advances and other Credit
Extensions in respect of the Revolving Line shall terminate on the Revolving Line Maturity Date. The principal amount of all Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line shall be immediately due and
payable on the Revolving Line Maturity Date. 
 2.1.2 Letters of Credit Sublimit. 
 (a) As part of the Revolving Line, Bank shall issue or have issued Letters of Credit for Borrower’s account, as requested by
Borrower. The aggregate face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit), plus any Letter of Credit Reserves, under this Agreement may not exceed $7,000,000, subject to the Combined LC Sublimit
set forth in Section 2.1.5(a). Such aggregate amounts utilized hereunder shall at all times reduce the amount otherwise available for Advances under the Revolving Line and the Combined Revolving Line. If, on the Revolving Line Maturity Date,
there are any outstanding Letters of Credit, then on such date Borrower shall provide to Bank cash collateral in an amount equal to 105% of the face amount of all such Letters of Credit plus all interest, fees, and costs due or to become due in
connection therewith (as estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to said Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and
shall be subject to the terms and conditions of Bank’s standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower agrees to execute any further documentation in connection with the Letters of
Credit as Bank may reasonably request. Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or by Bank’s interpretations of
any Letter of Credit issued by Bank for Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or
those contained in the Letters of Credit or any modifications, amendments, or supplements thereto. 
 (b) The obligation of
Borrower to immediately reimburse Bank for drawings made under Letters of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, such Letters of Credit, and the
Letter of Credit Application. Without limiting the generality of the foregoing, any payment by Bank under or in connection with a Letter of Credit shall constitute an Advance hereunder on the date such payment is made. 
 (c) Borrower may request that Bank issue a Letter of Credit payable in a Foreign Currency. If a demand for payment is made under any such
Letter of Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent of the amount thereof (plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges) in Dollars at the then-prevailing rate of
exchange in San Francisco, California, for sales of the Foreign Currency for transfer to the country issuing such Foreign Currency. 
 (d) To guard against fluctuations in currency exchange rates, upon the issuance pursuant to this Agreement of any Letter of Credit payable in a Foreign Currency, Bank shall create a reserve (the “Letter of Credit Reserve”)
under the Revolving Line in an amount equal to ten percent (10%) of the face amount of such Letter of Credit. The amount of the Letter of Credit Reserve may be adjusted by Bank from time to time to account for fluctuations in the exchange rate.
The availability of funds under the Revolving Line shall be reduced by the amount of such Letter of Credit Reserve for as long as such Letter of Credit remains outstanding and shall be subject to the Combined LC Sublimit set forth in
Section 2.1.5.

 2.1.3 Foreign Exchange Sublimit. As part of the Revolving Line, Borrower may enter into
foreign exchange contracts with Bank under which Borrower commits to purchase from or sell to Bank a specific amount of Foreign Currency (each, a “FX Forward Contract”) on a specified date (the “Settlement Date”).
FX Forward Contracts shall have a Settlement Date of at least one (1) FX Business Day after the contract date and shall be subject to a reserve of ten percent (10%) of each outstanding FX Forward Contract in a maximum aggregate amount
equal to $5,000,000 for all such FX Forward Contracts pursuant to this Agreement (the “FX Reserve”) and further subject to the Combined FX/CMS Sublimit set forth in Section 2.1.5. Subject to the Combined FX/CMS Sublimit
set forth in Section 2.1.5, the aggregate amount of FX Forward Contracts at any one time may not exceed ten (10) times the amount of the FX Reserve. Subject to the Combined FX/CMS Sublimit set forth in Section 2.1.5, the amount
otherwise available for Credit Extensions under the Revolving Line hereunder shall be reduced by an amount equal to ten percent (10%) of each outstanding FX Forward Contract (the “FX Reduction Amount”). Any amounts needed to
fully reimburse Bank in respect of FX Forward Contracts entered into pursuant to this Section 2.1.3 will be treated as Advances under the Revolving Line and will accrue interest at the interest rate applicable to Advances. 
 2.1.4 Cash Management Services Sublimit. Subject to the Combined FX/CMS Sublimit set forth in Section 2.1.5, Borrower may use up to
$5,000,000 (the “Cash Management Services Sublimit”) of the Revolving Line for Bank’s cash management services which may include merchant services, direct deposit of payroll, business credit card, and check cashing
services identified in Bank’s various cash management services agreements (collectively, the “Cash Management Services”). Any amounts Bank pays on behalf of Borrower, or any amounts that are not paid by Borrower, for any Cash
Management Services provided pursuant to this Section 2.1.4 will be treated as Advances under the Revolving Line and will accrue interest at the interest rate applicable to Advances. 
 2.1.5 Combined LC Sublimit; Combined FX/CMS Sublimit. 
 (a) Anything herein to the contrary notwithstanding, the sum of (i) the aggregate face amount of outstanding Letters of Credit
(including drawn but unreimbursed Letters of Credit) under this Agreement, plus any Letter of Credit Reserve under this Agreement, plus (ii) the aggregate face amount of outstanding “Letters of Credit” (including drawn but
unreimbursed “Letters of Credit”) under the Non-Exim Loan Agreement, plus any “Letter of Credit Reserve” under the Non-Exim Loan Agreement, shall not exceed $7,000,000 (the “Combined LC Sublimit”).

 (b) Anything herein to the contrary notwithstanding, the sum of (i) the FX Reserve under this Agreement, plus
(ii) the “FX Reserve” under the Non-Exim Loan Agreement, plus (iii) the aggregate amount of Obligations in respect of Cash Management Services under this Agreement, plus (iv) the aggregate amount of Obligations in respect of
“Cash Management Services” under the Non-Exim Loan Agreement, shall not exceed $5,000,000 (the “Combined FX/CMS Sublimit”). 
 2.2 Overadvances. If at any time or for any reason any one or more of the following occurs (in any such case, an “Overadvance”): 
 (a) the total of all outstanding Advances (including (i) amounts used hereunder for Cash Management Services, (ii) the
aggregate face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) under this Agreement, plus any Letter of Credit Reserve under this Agreement, and (iii) the FX Reduction Amount hereunder) exceeds the
lesser of (1) the Maximum Revolver Amount or (2) the Borrowing Base; or 
 (b) the sum of all outstanding
Advances (including (i) amounts used hereunder for Cash Management Services, (ii) the aggregate face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) under this Agreement, plus any Letter of
Credit Reserve under this Agreement, and (iii) the FX Reduction Amount hereunder) under this Agreement, plus all outstanding Non-Exim Loans (and other monetary “Obligations”) under the Non-Exim Loan Agreement (including
(iv) amounts used under the Non-Exim Loan Agreement for “Cash Management Services”, (v) the aggregate face amount of outstanding “Letters of Credit” (including drawn but unreimbursed “Letters of Credit”) under
the Non-Exim Loan Agreement, plus any “Letter of Credit Reserve” under the Non-Exim Loan Agreement, and (vi) the “FX Reduction Amount” under the Non-Exim Loan Agreement), exceeds the Maximum Combined Amount; or 

 

 4 

 (c) the sum of (i) the aggregate face amount of outstanding Letters of Credit
(including drawn but unreimbursed Letters of Credit) under this Agreement, plus any Letter of Credit Reserve under this Agreement, plus (ii) the aggregate face amount of outstanding “Letters of Credit” (including drawn but
unreimbursed “Letters of Credit”) under the Non-Exim Loan Agreement, plus any “Letter of Credit Reserve” under the Non-Exim Loan Agreement, exceeds the Combined LC Sublimit; or 
 (d) the sum of (i) the FX Reduction Amount under this Agreement, plus (ii) the “FX Reduction Amount” under the
Non-Exim Loan Agreement, plus (iii) the aggregate amount of Obligations in respect of Cash Management Services under this Agreement, plus (iv) the aggregate amount of Obligations in respect of “Cash Management Services” under the
Non-Exim Loan Agreement, exceeds the Combined FX/CMS Sublimit; 
 then, Borrower shall promptly pay to Bank in cash such Overadvance within one Business Day
following notice thereof from Bank to Borrower. Without limiting Borrower’s obligation to repay Bank any amount of the Overadvance, Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance, on demand, at the Default
Rate. 
 2.3 Payment of Interest on the Credit Extensions. 
 (a) Interest Rate. Subject to Section 2.3(b), the principal amount outstanding under the Revolving Line shall accrue interest
at a per annum rate equal to the sum of the Loan Margin plus the Prime Rate, provided that the interest rate in effect on any day shall not be less than 6.50% per annum, which interest shall be payable monthly. 
 As used herein, the term “Loan Margin” means, as of any date of determination, 2.50 percentage points. 
 (b) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear
interest at a rate per annum which is four percentage points above the rate which is otherwise applicable to the Obligations (the “Default Rate”). Payment or acceptance of the increased interest rate provided in this
Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Bank. 
 (c) Adjustment to Interest Rate. Changes to the interest rate of any Credit Extension based on changes to the Prime Rate shall be
effective on the effective date of any change to the Prime Rate and to the extent of any such change. 
 (d) 360-Day
Year. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed. 
 (e) Debit of
Accounts. Bank may debit any of Borrower’s deposit accounts, including the Designated Deposit Account, for (i) principal and interest payments, when due, or (ii) any other amounts Borrower owes Bank, when due. These debits shall
not constitute a set-off. 
 (f) [reserved] 
 (g) Payment; Interest Computation; Float Charge. Interest is payable monthly on the last calendar day of each month. In computing
interest on the Obligations, all Payments received after 12:00 p.m. Pacific time on any day shall be deemed received on the next Business Day. When the payment of an Obligation is due on a day that is not a Business Day, such payment shall be due
the next Business Day and additional fees or interest, as applicable, shall continue to accrue until such Obligation is paid. In addition, Bank shall be entitled to charge Borrower a “float” charge in an amount equal to two
(2) Business Days interest, at the interest rate applicable to the Advances, on all Payments received by Bank and applied to outstanding Advances. Said float charge is not included in interest for purposes of computing Minimum Monthly Interest
(if any) under this Agreement. The float charge for each month shall be payable on the last day of such month. Bank shall not, however, be required to credit Borrower’s account for the amount of any item of payment which is unsatisfactory to
Bank in its good faith business judgment, and Bank may charge Borrower’s Designated Deposit Account for the amount of any item of payment which is returned to Bank unpaid.

 2.4 Fees. Borrower shall pay to Bank: 
 (a) Combined Commitment Fee. The combined commitment fee (fully earned on the Effective Date) set forth in Section 2.4(a) of
the Non-Exim Loan Agreement.

renewal of Letters of Credit, upon the issuance, each anniversary of the issuance, and the renewal, of any such Letter of Credit by Bank. 
 (c) [intentionally omitted]

“Unused Combined Revolving Line Facility Fee” set forth in Section 2.4(d) of the Non-Exim Loan Agreement. Borrower shall not be entitled to any credit, rebate or repayment of any Unused Combined Revolving Line Facility Fee previously
earned by Bank pursuant to this Section notwithstanding any termination of the Agreement, or suspension or termination of Bank’s obligation to make loans and advances hereunder or under the Non-Exim Loan Agreement. 
 (e) Combined Collateral Monitoring Fee. With respect to any “Qualified CMF Month” (as defined in the Non-Exim Loan
Agreement), the monthly combined collateral monitoring fee set forth in Section 2.4(e) of the Non-Exim Loan Agreement. 
 (f) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses for documentation and negotiation of this Agreement and the other Loan Documents) incurred through and after the Effective Date, when due.

 4 CREATION OF SECURITY 
 4.1 Grant of Security Interest. Each Borrower hereby grants Bank, to secure the payment and performance in full of all of the Obligations,
continuing security interests in, and pledges to Bank, all right, title, and interest of such Borrower in and to the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrower
represents, warrants, and covenants that the security interests granted herein are and shall at all times continue to be first priority perfected security interests in the Collateral (subject in lien priority only to those Permitted Liens that are
expressly entitled to such priority over the security interests of Bank by operation of law or by written subordination agreement duly executed and delivered by Bank in favor of the holders of such Permitted Liens). If Borrower shall acquire one or
more commercial tort claims involving amounts in excess of $250,000 (individually or in the aggregate with respect to all such acquired commercial tort claims), Borrower shall promptly notify Bank in a writing signed by Borrower of the general
details thereof (unless and except to the extent such information would waive the attorney-client privilege). Such notification to Bank shall constitute an additional grant, hereunder, of a continuing security interest in the commercial tort claims
and all proceeds thereof to Bank, and Borrower shall execute and deliver all such documents and take all such actions as Bank may reasonably request in connection therewith. 
 If both this Agreement and the Exim Loan Agreement are terminated, Bank’s Lien in the Collateral shall continue until the Obligations (other than
inchoate indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such time as Bank’s obligation to make Credit Extensions under this Agreement and the
Exim Loan Agreement has terminated, Bank shall, at Borrower’s sole cost and expense, promptly release its Liens in the Collateral and all rights therein shall revert to Borrower. 
 4.2 Authorization to File Financing Statements. Borrower hereby authorizes Bank to file financing statements, without notice to Borrower, with all
appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral prohibited under the Loan Documents, by either Borrower or any other Person, shall be deemed to
violate the rights of Bank under the Code. Such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Bank’s
discretion. 
 5 REPRESENTATIONS AND WARRANTIES 
 Borrower represents, warrants, and agrees, as follows: 
 5.1 Due Organization, etc.; Authorization; Power
and Authority; Material Domestic Subsidiaries. 
 (a) Borrower and each of its Subsidiaries are duly existing and in good
standing in their respective jurisdictions of formation and are qualified and licensed to do business and are in good standing in any jurisdiction in which the conduct of their business or their ownership of property requires that they be qualified
except where the failure to do so could not reasonably be expected to result in a Material Adverse Change; provided, however, that with respect to Xybridge Technologies, Inc., a Texas corporation (which is not in good standing with the
Texas Comptroller of Public Accounts as of February 20, 2009), Borrower shall deliver to Bank, no later than 60 days 

  

 8 

 
following the Effective Date, evidence of Xybridge Technologies, Inc.’s good standing with the Texas Comptroller of Public Accounts as of a date on or
after the Effective Date. In connection with this Agreement, Borrower has delivered to Bank, a separate completed certificate (for each of the Borrowers), dated on or about the Effective Date, signed by the applicable Borrower (individually and
collectively, the “Perfection Certificate”). Borrower represents and warrants to Bank that: (i) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof;
(ii) Borrower is an organization of the type and is organized in the jurisdiction set forth in the Perfection Certificate; (iii) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or
accurately states that Borrower has none; (iv) the Perfection Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing address (if different than
its chief executive office); (v) Borrower (and each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its
jurisdiction, in each case, except as expressly identified in the Perfection Certificate; and (vi) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete in all
material respects (it being understood and agreed that Borrower may from time to time update certain information in the Perfection Certificate after the Effective Date to the extent permitted by one or more specific provisions in this Agreement). If
Borrower is not now a Registered Organization but later becomes one, Borrower shall promptly notify Bank of such occurrence and provide Bank with Borrower’s organizational identification number. 
 (b) The execution, delivery and performance by Borrower of the Loan Documents to which it is a party have been duly authorized, and do not
(i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate, in any material respect,
any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any its Subsidiaries or any of their property or assets (other than immaterial property and immaterial assets) may be
bound or affected, (iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and
effect), or (v) constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could reasonably be
expected to result in a Material Adverse Change. 
 (c) Concurrently herewith, Borrower has caused the following companies
(the “Existing Guarantors”) to each execute and deliver to Bank the Guaranty and the Guarantor Security Agreement: 
 (1) Paradyne Corporation; 
 (2) Paradyne Networks, Inc.; 
 (3) Premisys Communications, Inc.; 
 (4) Xybridge Technologies, Inc.; and 
 (5) Zhone Technologies International, Inc. 

Borrower represents and warrants that the Existing Guarantors are all of its domestic subsidiaries constituting Material Domestic
Subsidiaries (as defined below) as of the Effective Date, except for Zhone Technologies Campus, LLC (“Campus”), which Borrower represents and warrants is a special purpose limited liability company whose sole asset is real property
utilized by Borrower and which is not permitted to guaranty the obligations of the Borrower under its agreement with its lender. In the event that, in the future, any other Domestic Subsidiaries of Borrower become Material Domestic Subsidiaries,
Borrower shall promptly cause any such additional Domestic Subsidiaries to execute and deliver to Bank a Guaranty and a Security Agreement, together with related documentation and certified resolutions or other evidence of authority with respect to
the execution and delivery of such Loan Documents. Throughout the term of this Agreement Borrower shall cause the Guaranties and Security Agreements referred to in this Section to continue in full force and effect. It is acknowledged that the former
California corporation domestic subsidiary of Borrower known as VPacket Communications, Inc. was merged with and into ZMS-III on or about 12/18/2006. 
  

 9 

 As used herein, the term “Material Domestic Subsidiary” means any domestic
subsidiary of Borrower, other than a domestic subsidiary of Borrower that has less than $200,000 in tangible assets and less than $1,000,000 in fair market value of total assets. 
 5.2 Collateral. 
 (a) Borrower has good title to the Collateral, free of Liens except Permitted Liens. Borrower has no deposit account other than the deposit accounts with Bank and deposit accounts described in the Perfection Certificate delivered to
Bank in connection herewith or as disclosed to Bank pursuant to Section 6.8(b), other than deposit accounts not required to be disclosed pursuant to Section 6.8(b). The Accounts are bona fide, existing obligations of the Account Debtors.

 (b) The Collateral is not in the possession of any third party bailee (such as a warehouse), except for Permitted
Locations. None of the components of the Collateral with an aggregate value in excess of $500,000 shall be maintained at locations other than Permitted Locations or as permitted pursuant to Section 7.2. In the event that Borrower, after the
date hereof, intends to store or otherwise deliver any portion of the Collateral with an aggregate value in excess of $500,000 to any one or more bailees, then Borrower shall, promptly upon Bank’s request therefor, use commercially reasonable
efforts to deliver to Bank a bailee agreement (in form and substance satisfactory to Bank in its good faith business judgment) duly executed by such bailee. In the event that Bank requests such a bailee agreement and Borrower uses such efforts but
does not succeed in delivering such a bailee agreement, Bank may (in its good faith business judgment) maintain a Reserve with respect to the Collateral located with such bailee. 
 (c) With respect to any leased premises of Borrower at which Collateral with an aggregate value of more than $500,000 is located,
Borrower shall, promptly upon Bank’s request therefor, use commercially reasonable efforts to deliver to Bank a landlord agreement (in form and substance satisfactory to Bank in its good faith business judgment) duly executed by the lessor of
such leased premises. Without limiting the generality of the foregoing, Borrower shall use such efforts to obtain from the applicable landlord, no later than 60 days following the Effective Date, landlord agreements (in form and substance
satisfactory to Bank) duly executed by such landlords in favor of Bank in respect of the following leased locations of Borrower: (1) 7001 Oakport Street, Oakland, CA 94621; (2) 8545 126th Avenue N. (G Building), Largo, FL 33773; and
(3) 8625 126th Avenue N., Suite 100 (H Building), Largo, FL 33773. In the event that Bank requests such a landlord agreement and Borrower uses such efforts but does not succeed in delivering such a landlord agreement, Bank may (in its good
faith business judgment) maintain a Reserve with respect to such leased premises. 
 (d) All Inventory is in all
material respects of good and marketable quality, free from material defects, except for Inventory for which adequate reserves are maintained in accordance with GAAP. 
 (e) Borrower is the sole owner of its intellectual property, except for (i) non-exclusive licenses granted by Borrower as
licensor to third-parties, and (ii) such intellectual property as is licensed by Borrower as a licensee. Each patent owned by Borrower that is material to Borrower’s business is valid and enforceable, and, to Borrower’s knowledge, no
part of the intellectual property that is material to Borrower’s business has been judged invalid or unenforceable, in whole or in part, and to Borrower’s knowledge, no claim has been made that any part of the intellectual property that is
material to Borrower’s business violates, in any material respect, the rights of any third party, except to the extent such claim could not reasonably be expected to result in a Material Adverse Change. 
 (f) Except as noted on the Perfection Certificate (or as disclosed to Bank in written updates of the Perfection Certificate with
respect to the following), Borrower is not a party to, nor is bound by, any material license or other agreement with respect to which Borrower is the licensee (other than over-the-counter or shrink-wrap software licenses generally available to the
public) relating to any material product lines of Borrower or Guarantor (i) that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property (to the
extent such prohibition is enforceable), or (ii) for which a default under or termination of could interfere in any material respect with Bank’s right to sell any Collateral. Borrower shall provide written notice to Bank within thirty
(30) days of entering or becoming bound by any such license or agreement which is reasonably likely to have a material impact on Borrower’s business or financial condition (other than over-the-counter software that is commercially
available to the public). Upon Bank’s request, Borrower shall use commercially reasonable efforts to promptly obtain the consent of, or waiver by, any person 

  

 10 

 
whose consent or waiver is necessary for (x) all such licenses or agreements to be deemed “Collateral” and for Bank to have a security
interest in the same that is otherwise restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future, and (y) Bank to have the ability in the event of a liquidation of any
Collateral to dispose of such Collateral in accordance with Bank’s rights and remedies under this Agreement and the other Loan Documents. If Borrower is unsuccessful in obtaining any such consent or waiver requested by Bank, then Borrower shall
notify Bank in writing of same. 
 5.3 Accounts Receivable. 
 (a) For each Account with respect to which Advances are requested, on the date each Advance is requested and made, such Account shall be
an Eligible Account. 
 (b) All statements made and all unpaid balances appearing in all invoices, instruments and other
documents evidencing such Eligible Accounts are and shall be true and correct in all material respects as of the date such statement is made or such unpaid balance is disclosed to Bank, and all such invoices, instruments and other documents, and all
of Borrower’s Books, are genuine and in all material respects what they purport to be. Whether or not an Event of Default has occurred and is continuing, Bank may notify any Account Debtor owing Borrower money of Bank’s security interest
in such funds and verify the amount of such Eligible Account. All sales and other transactions underlying or giving rise to each Account shall comply in all material respects with all applicable laws and governmental rules and regulations. Borrower
has no knowledge of any actual or imminent Insolvency Proceeding of any Account Debtor whose accounts are shown as Eligible Accounts in any Transaction Report. To the best of Borrower’s knowledge, all signatures and endorsements on all
documents, instruments, and agreements relating to all Eligible Accounts are and will be genuine, and, to the best of Borrower’s knowledge, all such documents, instruments and agreements are and will be legally enforceable in accordance with
their terms. 
 5.4 Litigation. Except as disclosed to the Bank in writing, there are no actions or proceedings pending or, to the
knowledge of the Responsible Officers, threatened in writing by or against Borrower or any of its Subsidiaries involving more than $250,000 or more in the aggregate. 
 5.5 No Material Deviation in Financial Statements. All consolidated financial statements for Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s
consolidated financial condition and Borrower’s consolidated results of operations as of the date of such financial statements, except that that interim financial statements may be subject to normal year-end audit adjustments (which will not be
material in the aggregate) and need not contain footnote disclosures required by GAAP. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted
to Bank. 
 5.6 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the
fair value of its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature. 
 5.7 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled” by an “investment
company” under the Investment Company Act of 1940, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). Borrower
has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary
company” of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to cause
a Material Adverse Change. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing,
treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all Government
Authorities that are necessary to continue their respective businesses as currently conducted. 
 5.8 Subsidiaries; Investments.
Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments. 
  

 11 

 5.9 Tax Returns and Payments; Pension Contributions. Borrower has timely filed (i) all
required federal tax returns and reports, and (ii) all required state, local, and foreign, material tax returns and reports. Subject to Borrower’s right to contest taxes in accordance with the immediately following sentence, Borrower has
timely paid all federal taxes, assessments, deposits and contributions owed by Borrower, and all state, local, and foreign, material taxes, assessments, deposits and contributions owed by Borrower. Borrower may defer payment of any contested taxes,
provided that Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any material
development in, such proceedings, and (c) posts bonds or takes any other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted
Lien”. Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower and which have not been timely discharged or contested in
accordance with the immediately preceding sentence. Borrower has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation
in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the
Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
 5.10 Use of Proceeds. Borrower shall use
the proceeds of the Credit Extensions solely for the purposes specified in the Exim Borrower Agreement, and Borrower will not use the proceeds of the Exim Loans for any purpose prohibited by the Exim Borrower Agreement. Without limiting the
generality of the foregoing, any “Credit Accommodations” (as such term is defined in the Exim Borrower Agreement) made by Bank to Borrower for any of the purposes set forth in Section 2.01(a)(i)-(iv) of the Exim Borrower
Agreement shall be deemed made under (and shall be subject to the terms and conditions of) the Non-Exim Loan Agreement as a Non-Exim Loan instead of under this Agreement as an Exim Loan. 
 5.11 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, as
of the date such representation, warranty, or other statement was made, taken together with all such written certificates and written statements given to Bank, contains any untrue statement of a material fact or omits to state a material fact
necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as
facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results). 
 6 AFFIRMATIVE COVENANTS 
 Borrower shall do all of the following: 
 6.1 Government Compliance. (a) Maintain its and all its Subsidiaries’ legal existence and good standing in their respective
jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to cause a Material Adverse Change; provided, however, that with respect to Xybridge
Technologies, Inc., a Texas corporation (which is not in good standing with the Texas Comptroller of Public Accounts as of February 20, 2009), Borrower shall deliver to Bank, no later than 60 days following the Effective Date, evidence of
Xybridge Technologies, Inc.’s good standing with the Texas Comptroller of Public Accounts as of a date on or after the Effective Date. Borrower shall comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it
is subject, noncompliance with which could reasonably be expected to cause a Material Adverse Change. 
 (b) Obtain all of the
Governmental Approvals necessary for the performance by Borrower of its obligations under the Loan Documents to which it is a party and the grant of a security interest to Bank in all of its property. Borrower shall promptly provide copies of any
such obtained Governmental Approvals to Bank. 
  

 12 

 6.2 Financial Statements, Reports, Certificates. 
 (a) Borrower shall provide Bank with the following written reports, and such other written reports with respect to Borrower (including
budgets, sales projections, operating plans and other financial documentation, and lists of stockholders of record), as Bank shall from time to time specify in its good faith business judgment: 
  

	 	(i) 	a Transaction Report, (i) at the time of each Advance, and (ii) so long as any Advance is outstanding, in addition not less frequently than weekly;

  

	 	(ii) 	within fifteen (15) days after the end of each month: 

  

	 	(A) 	(1) monthly accounts receivable agings, aged by invoice date; and (2) concurrently with such monthly accounts receivable agings in respect of any month that is also the last
month of a fiscal quarter, copies of actual invoices in respect of Eligible Accounts representing not less than 10% of the aggregate accounts receivable agings balance as of the end of such last month of a fiscal quarter; 

 

	 	(B) 	monthly accounts payable agings, aged by invoice date, and outstanding or held check registers, if any; 

  

	 	(C) 	monthly reconciliations of accounts receivable agings (aged by invoice date), Transaction Reports, and general ledger; 

  

	 	(D) 	[intentionally omitted] 

  

	 	(E) 	monthly Deferred Revenue reports; 

  

	 	(iii) 	as soon as available, and in any event within thirty (30) days after the end of each month, monthly unaudited financial statements; 

  

	 	(iv) 	within thirty (30) days after the end of each month a monthly Compliance Certificate signed by a Responsible Officer, certifying that as of the end of such month, Borrower was
in full compliance with all of the terms and conditions of this Agreement, and setting forth calculations showing compliance with the financial covenants set forth in this Agreement and such other information as Bank shall reasonably request,
including, without limitation, a statement that at the end of such month there were no held checks; 

  

	 	(v) 	within thirty (30) days after the end of each fiscal quarter, a written status update with respect to Borrower’s ongoing discussions with the New Jersey tax authority
regarding the New Jersey sales & use tax obligation of Zhone (for the period covering 10/01/2001 – 09/30/2003) described in the Perfection Certificate; provided, however, that in addition, Borrower shall also deliver such a status
update (irrespective of whether such quarterly report is then due) of, and promptly upon, the occurrence of a material adverse development (if any) in such discussions with the New Jersey tax authority regarding such tax obligation;

  

	 	(vi) 	as soon as available, and in any event within thirty (30) days prior to the end of each fiscal year of Borrower, (A) annual financial projections and operating budgets
(including income statements, balance sheets and cash flow statements, by month) for the upcoming fiscal year (on a monthly basis) of Borrower, as approved by Borrower’s board of directors; and 

  

	 	(vii) 	as soon as available, and in any event within 120 days following the end of Borrower’s fiscal year, annual financial statements certified by, and with an unqualified opinion
of, independent certified public accountants reasonably acceptable to Bank. 

 (b) At all times that Borrower is
subject to the reporting requirements under the Securities Exchange Act of 1934, as amended, within five (5) days after filing, all reports on Form 10-K, 10-Q and 8-K filed with the Securities and Exchange Commission or a link thereto on
Borrower’s or another website on the Internet. 
 (c) Prompt written notice of (i) any material change in the
composition of the intellectual property, (ii) the registration (or filed application for registration) of any copyright (including any subsequent ownership right of Borrower in or to any copyright), any patent (including any subsequent
ownership right of Borrower in or to any patent) constituting Material Intellectual Property, or any trademark (including any subsequent ownership right of Borrower in or to any trademark) constituting Material Intellectual Property, in each case,
that is not previously disclosed in writing to Bank, or (iii) Borrower’s knowledge of an event that materially adversely affects the value of the intellectual property. 
  

 13 

 6.3 Accounts Receivable. 
 (a) Schedules and Documents Relating to Accounts. Borrower shall deliver to Bank transaction reports and schedules of
collections, as provided in Section 6.2, on Bank’s standard forms; provided, however, that Borrower’s failure to execute and deliver the same shall not affect or limit Bank’s Lien and other rights in all of Borrower’s
Accounts, nor shall Bank’s failure to advance or lend against a specific Account affect or limit Bank’s Lien and other rights therein. If requested by Bank, Borrower shall furnish Bank with copies (or, at Bank’s request, originals) of
all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Accounts. Without
limiting the generality of the foregoing, Borrower shall deliver to Bank the copies of the invoices required under Section 6.2(a)(ii)(A)(2) above. In addition, Borrower shall deliver to Bank, on its request, the originals of all instruments,
chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary endorsements, and copies of all credit memos. 
 (b) Disputes. Borrower shall promptly notify Bank of all disputes or claims relating to Accounts, in excess of $250,000
individually or in the aggregate at any one time, on the Transaction Reports. Borrower may forgive (completely or partially), compromise, or settle any Account for less than payment in full, or agree to do any of the foregoing so long as
(i) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, in arm’s-length transactions, and reports the same to Bank in the regular reports provided to Bank; (ii) no Event of Default
has occurred and is continuing; and (iii) after taking into account all such discounts, settlements and forgiveness, no Overadvance exists. 
 (c) Collection of Accounts. Borrower shall have the right to collect all Accounts, unless and until a Default or an Event of Default has occurred and is continuing. Whether or not an Event of Default has
occurred and is continuing, Borrower shall hold all payments on, and proceeds of, Accounts in trust for Bank, and Borrower shall immediately deliver all such payments and proceeds to Bank in their original form, duly endorsed, which payments and
proceeds shall be applied to the Obligations pursuant to the terms of Section 9.4 hereof. Bank may, in its good faith business judgment, require that all proceeds of Accounts be deposited by Borrower into a lockbox account, or such other
“blocked account” as Bank may specify, pursuant to a blocked account agreement in such form as Bank may specify in its good faith business judgment. 
 (d) Returns. Provided no Event of Default has occurred and is continuing, if any Account Debtor returns any Inventory to
Borrower, Borrower shall promptly (i) determine the reason for such return, (ii) issue a credit memorandum to the Account Debtor in the appropriate amount, and (iii) in the event that the amount of such credit memorandum, individually
or in the aggregate, exceeds $250,000, provide a copy of each such credit memorandum to Bank. In the event any attempted return occurs after the occurrence and during the continuance of any Event of Default, Borrower shall hold the returned
Inventory in trust for Bank, and immediately notify Bank of the return of the Inventory. 
 (e)
Verification. Bank may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts, either in the name of Borrower or Bank or such other name as Bank may
choose. 
 (f) No Liability. Bank shall not be responsible or liable for any shortage or discrepancy in, damage
to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any
Account, or for settling any Account in good faith for less than the full amount thereof, nor shall Bank be deemed to be responsible for any of Borrower’s obligations under any contract or agreement giving rise to an Account. Nothing herein
shall, however, relieve Bank from liability for its own gross negligence or willful misconduct. 
 6.4 Remittance of Proceeds. Except
as otherwise provided in Section 6.3(c), deliver, in kind, all proceeds arising from the disposition of any Collateral to Bank in the original form in which received by Borrower not later than the following Business Day after receipt by
Borrower, which, shall be dealt with as provided in Section 6.3(c); provided that, if no Default or Event of Default has occurred and is continuing, Borrower shall not be 

  

 14 

 
obligated to remit to Bank the proceeds of the sale of worn out, surplus, or obsolete Equipment disposed of by Borrower in good faith in an arm’s length
transaction for an aggregate purchase price of $250,000 or less (for all such transactions in any fiscal year). Borrower agrees that it will not commingle proceeds of Collateral with any of Borrower’s other funds or property, but will hold such
proceeds separate and apart from such other funds and property and in an express trust for Bank. Nothing in this Section limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement. 
 6.5 Taxes; Pensions. Timely file, and require each of its Subsidiaries to timely file, all required federal tax returns and reports (and all
required state, local, and foreign, material tax returns and reports), and timely pay, and require each of its Subsidiaries to timely file, all federal taxes, assessments, deposits and contributions (and all state, local, and foreign, material
taxes, assessments, deposits and contributions) owed by Borrower and each of its Subsidiaries, except for deferred payment of any taxes contested pursuant to the terms of Section 5.9 hereof, and shall deliver to Bank, on demand, appropriate
certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms. 
 6.6 Access to Collateral; Books and Records. At reasonable times, on at least one (1) Business Day’s notice (provided no notice is
required if an Event of Default has occurred and is continuing), Bank, or its agents, shall have the right to inspect the Collateral and the right to audit and copy Borrower’s Books; provided, however, that, so long as no Event of Default has
occurred and is continuing, any audits shall be conducted no more often than once every 6 months (it being understood that audits taking place at one or more locations of Borrower during substantially the same overall examination period shall
constitute but a single audit for purposes of the foregoing proviso). The foregoing inspections and audits shall be at Borrower’s expense, and the charge therefor shall be $750 per person per day (or such higher amount as shall represent
Bank’s then-current standard charge for the same), plus reasonable out-of-pocket expenses. In the event Borrower and Bank schedule an audit more than ten (10) days in advance, and Borrower cancels or seeks to reschedules the audit with
less than ten (10) days written notice to Bank, then (without limiting any of Bank’s rights or remedies), Borrower shall pay Bank a fee of $1,000 plus any out-of-pocket expenses incurred by Bank to compensate Bank for the anticipated costs
and expenses of the cancellation or rescheduling. 
 6.7 Insurance. Keep its business and the Collateral insured for risks and in
amounts standard for companies in Borrower’s industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are satisfactory to Bank. All property policies shall have a
lender’s loss payable endorsement showing Bank as lender loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or the lender loss payable
and additional insured endorsements) shall provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall deliver certified copies of
policies and evidence of all premium payments. Proceeds payable under any policy shall (subject only to the applicable senior claims of those holders of Permitted Liens that are expressly entitled to lien priority over the security interests of Bank
in the applicable insured Collateral by operation of law or by written subordination agreement duly executed and delivered by Bank in favor of the holders of such Permitted Liens), at Bank’s option, be payable to Bank on account of the
Obligations. Notwithstanding the foregoing, (a) so long as no Event of Default has occurred and is continuing, Borrower shall have the option of applying the proceeds of any casualty policy up to $250,000, in the aggregate, toward the
replacement or repair of destroyed or damaged property; provided that any such replaced or repaired property shall be deemed Collateral in which Bank has been granted a first priority security interest (subject in lien priority only to those
Permitted Liens described in clause (c) of the definition of “Permitted Liens”, if any, that are applicable to such replaced or repaired property), and (b) after the occurrence and during the continuance of an Event of Default,
all proceeds payable under such casualty policy shall, at the option of Bank, be payable to Bank on account of the Obligations. If Borrower fails to obtain insurance as required under this Section 6.7 or to pay any amount or furnish any
required proof of payment to third persons and Bank, Bank may make all or part of such payment or obtain such insurance policies required in this Section 6.7, and take any action under the policies Bank deems prudent. 
 6.8 Operating Accounts. 
 (a) Maintain all of its and its Subsidiaries’ primary depository and operating accounts and securities accounts with Bank and Bank’s Affiliates, which accounts shall represent at least 85% of the dollar value of Borrower’s
and such Subsidiaries accounts at all financial institutions. 
  

 15 

 (b) Provide Bank five (5) days prior written notice before Borrower or any of its
Subsidiaries establishes or has any Collateral Account at or with any bank or financial institution other than Bank or Bank’s Affiliates, if such Collateral Account is not expressly identified on the Perfection Certificate and if Borrower holds
a balance of more than $20,000 in such Collateral Account (except that the total of amounts in all Collateral Accounts with a balance of $20,000 or less and as to which written notice of the same is not given to Bank shall not exceed $250,000 in the
aggregate). In addition, for each Collateral Account that Borrower or any Guarantor at any time maintains, Borrower shall, upon Bank’s request, cause the applicable bank or financial institution (other than Bank) at or with which any such
Collateral Account is maintained to execute and deliver a Control Agreement or other appropriate instrument with respect to such Collateral Account to perfect Bank’s Lien in such Collateral Account in accordance with the terms hereunder. The
provisions of the previous sentence shall not apply to (i) deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s or Guarantor’s employees and
identified to Bank by Borrower or Guarantor as such, and (ii) deposit accounts located outside the United States used to facilitate payment of local operating expenses provided that the amount on deposit in any such account described in this
clause (ii) shall not exceed, at any time, the amount necessary to fund operating expenses for such jurisdiction for the then current fiscal quarter. Without limiting the generality of the foregoing, Borrower and Bank hereby agree that:
(1) no later than 60 days following the Effective Date, Borrower and Guarantor shall cause Wachovia Bank to execute and deliver such a Control Agreement in favor of Bank with respect to the Collateral Accounts of Borrower and Guarantor
maintained with Wachovia Bank; and (2) no Control Agreement by Wells Fargo in favor of Bank shall be required under this Section 6.8(b) so long as the total amount of funds of all Borrowers and all Guarantors on deposit in any and all
Collateral Accounts of Borrower and Guarantor maintained with Wells Fargo does not exceed $250,000 in the aggregate. 
 6.9 Financial
Covenants. Borrower shall maintain at all times, to be tested as of the last day of each month, unless otherwise noted, on a consolidated basis with respect to Borrower and its Subsidiaries:

Intellectual Property”); (b) promptly advise Bank in writing of known material infringements of its Material Intellectual Property; and (c) not allow any Material Intellectual Property to be abandoned, forfeited or dedicated to the
public without Bank’s written consent. Borrower hereby represents and warrants that, as of the Effective Date, Borrower does not own any maskworks, computer software, or other copyrights of Borrower that are registered (or the subject of an
application for registration) with the United States Copyright Office (collectively, the “Registered Copyrights”). Borrower will NOT register with the United States Copyright Office (or apply for such registration of) any of
Borrower’s maskworks, computer software, or other copyrights, unless Borrower: (x) provides Bank with at least fifteen (15) days prior written notice of its intent to register such copyrights or mask works together with a copy of the
application it intends to file with the United States Copyright Office (excluding exhibits thereto); (y) executes and delivers a security agreement or such other documents as Bank may reasonably request to maintain the perfection and priority
of Bank’s security interest in the copyrights or mask works intended to be registered with the United States Copyright Office; and (z) records such security agreement with the United States Copyright Office contemporaneously with or
promptly (but in no event more than 10 days) after filing the copyright or mask work application(s) with the United States Copyright Office. Borrower shall promptly provide to Bank a copy of the application(s) actually filed with the United States
Copyright Office together with evidence of the recording of the security agreement necessary for Bank to maintain the perfection and priority of its security interest in the copyrights or mask works intended to be registered with the United States
Copyright Office. Borrower hereby represents and warrants that, as of the Effective Date, the IP Security Agreement identifies all patents (constituting Material Intellectual Property) and trademarks (constituting Material Intellectual Property) of
Borrower that are registered (or the subject of an application for registration) with the United States Patent and Trademark Office. From and after the Effective Date, Borrower shall provide written notice to Bank of any application filed by
Borrower in the United States Patent and Trademark Office for a patent (constituting Material Intellectual Property) or to register a trademark (constituting Material Intellectual Property) or service mark (constituting Material Intellectual
Property) within 30 days after any such filing, and, upon the request of Bank, Borrower shall promptly execute and deliver a security agreement or such other documents as Bank may reasonably request with respect to such additional patents
(constituting Material Intellectual Property) and/or trademarks (constituting Material Intellectual Property) of Borrower that are registered (or the subject of an application for registration) with the United States Patent and Trademark Office. The
foregoing notwithstanding, Bank shall not acquire any interest in any intent to use a federal trademark application for a trademark, servicemark, or other mark filed on Borrower’s behalf prior to the filing under applicable law of a verified
statement of use (or equivalent) for such mark that is the subject of such application. 
 6.11 Litigation Cooperation. From the date
hereof and continuing through the termination of this Agreement, make available to Bank, without expense to Bank, Borrower and its officers, employees and agents and Borrower’s books and records, to the extent that Bank may deem them reasonably
necessary to prosecute or defend any third-party suit or proceeding instituted by or against Bank with respect to any Collateral or relating to Borrower. 
  

 17 

 6.12 Intercompany Debt. All present and future indebtedness of Borrower and any Guarantor
owed or owing to any one or more of Borrower, any Guarantor, or any other Affiliate of Borrower or any other Affiliate of any Guarantor shall, at all times, be subordinated to the Obligations pursuant to a subordination agreement on Bank’s
standard form (the “Intercompany Subordination Agreement”). 
 6.13 [intentionally omitted] 
 6.14 Further Assurances. Borrower shall execute any further instruments and take further action as Bank reasonably requests to perfect or continue
Bank’s Lien in the Collateral or to effect the purposes of this Agreement. 
 7 NEGATIVE COVENANTS 
 Borrower shall not do any of the following without Bank’s prior written consent: 
 7.1 Dispositions. Convey, sell, lease, transfer or otherwise dispose of (collectively, “Transfer”), or permit any of its
Subsidiaries to Transfer, all or any part of its business or property, except for (A) the sale of Inventory in the ordinary course of Borrower’s business, (B) the sale or other disposition of obsolete or unneeded Equipment in the
ordinary course of business; (C) non-exclusive licenses and similar non-exclusive arrangements for the use of the property of Borrower; (D) Transfers consisting of the granting of Permitted Liens or the making of Permitted Investments or

 (d) without at least ten (10) days prior written notice to Bank, add any new offices or business locations, including warehouses

 (b) acquire, or permit any of its Subsidiaries to acquire, all or substantially all of the capital stock or property of another Person;

 in each case (of (a) or (b) above), provided however that (i) prior or concurrent written notice by Borrower to Bank (rather than such
written consent of Bank) is required with respect to any such transaction as to which Borrower (or, as to any such transaction to which Borrower is not a party, such Subsidiary) is the surviving or successor person and no Default or Event of
Default has occurred and is continuing or would result therefrom, and (ii) a Subsidiary of Borrower may merge or consolidate into another Subsidiary of Borrower. 
  

 18 

 In connection with any such acquisition, Borrower may create a subsidiary that has nominal assets (and would not
constitute a Material Domestic Subsidiary prior to giving effect to the acquisition) solely for the purpose of and in preparation for such acquisition prior to obtaining Bank’s consent. 
 7.4 Indebtedness. Create, incur, assume, or be liable for any Indebtedness, or permit any Subsidiary of Borrower to do so, other than Permitted
Indebtedness. 
 7.5 Encumbrance. Create, incur, allow, or suffer any Lien on any of the Collateral, or assign or convey any right to
receive income, including the sale of any Accounts, or permit any of its Subsidiaries to do so, except for Permitted Liens, permit any Collateral not to be subject to the first priority security interests of Bank therein (subject in lien priority
only to those Permitted Liens that are expressly entitled to such priority over the security interests of Bank by operation of law or by written subordination agreement duly executed and delivered by Bank in favor of the holders of such Permitted
Liens), or enter into any agreement, document, instrument or other arrangement (except with or in favor of Bank) with any Person which directly or indirectly prohibits or has the effect of prohibiting Borrower or any Subsidiary from assigning,
mortgaging, pledging, granting a security interest in or upon, or encumbering any of Borrower’s or any Subsidiary’s owned (as opposed to licensed) Material Intellectual Property, except as is otherwise permitted in Section 7.1 hereof
and the definition of “Permitted Lien” herein. 
 7.6 Maintenance of Collateral Accounts. Maintain any Collateral Account
except pursuant to the terms of Section 6.8.(b) hereof. 
 7.7 Investments; Distributions; Special Investment re Campus Real Estate
Loan. (a) Directly or indirectly make any Investment other than Permitted Investments, or permit any of its Subsidiaries to do so; or (b) pay any dividends or make any distribution or payment or redeem, retire or purchase any capital
stock, provided that (i) Zhone may convert any of its convertible securities into other securities pursuant to the terms of such convertible securities or otherwise in exchange thereof, (ii) Borrower may pay dividends solely in equity
securities; (iii) Zhone may repurchase the stock of former employees, directors, or consultants pursuant to stock repurchase agreements so long as no Default or Event of Default has occurred at the time of such repurchase and would not exist
after giving effect to such repurchase, provided such repurchase does not exceed in the aggregate of $250,000 per fiscal year; and (iv) payments of dividends or distributions made by (x) any Borrower to any other Borrower, or (y) any
Subsidiary of Borrower to Borrower, or (z) any Subsidiary of Borrower to any other Subsidiary of Borrower, are expressly permitted. With respect to the real estate loan of Campus secured by the real property used by Borrower, Borrower may make
Investments in Campus solely for the purpose of funding, when due, regularly scheduled principal and interest payments in respect of such real estate loan, provided that (i) no Event of Default has occurred and is continuing or would result
therefrom, and (ii) after giving pro forma effect to such Investment, Borrower would be in compliance with the financial covenant(s) in Section 6.9. 
 7.8 Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction with any Affiliate of Borrower, except for transactions that are upon fair and reasonable terms
and no less favorable to Borrower than would be obtained in an arm’s length transaction with a non-Affiliated Person, other than bona fide sales of Borrower’s equity securities. 
 7.9 Subordinated Debt. Without Bank’s prior written consent, (a) make or permit any payment on any Subordinated Debt, except under the
terms of the subordination, intercreditor, or other similar agreement to which such Subordinated Debt is subject, or (b) amend any provision in any document relating to the Subordinated Debt which would increase the amount thereof or the amount
of any permitted payments thereunder or adversely affect the subordination thereof to Obligations owed to Bank. 
 7.10 Compliance.
Become an “investment company” or a company controlled by an “investment company”, under the Investment Company Act of 1940, as amended, or undertake as one of its important activities extending credit to purchase or carry margin
stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System), or use the proceeds of any Credit Extension for that purpose; fail to meet the minimum funding requirements of ERISA, permit a Reportable Event or Prohibited
Transaction, as defined in ERISA, to occur; fail to comply with the Federal Fair Labor Standards Act or violate any other law or regulation, if the violation could reasonably be expected to cause a Material Adverse Change, or permit any of its
Subsidiaries to do so; withdraw or permit any Subsidiary to withdraw from participation in, permit partial or complete termination of, or permit the occurrence of any other event with respect to, any present pension, profit sharing and deferred
compensation plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
  

 19

 Any one of the following shall constitute an event of default (an “Event of Default”) under this Agreement: 
 8.1 Payment Default. Borrower fails to (a) make any payment of principal or interest on any Credit Extension on its due date, or (b) pay
any other Obligations within three (3) Business Days after such Obligations are due and payable (which three (3) day grace period shall not apply to payments due on the Revolving Line Maturity Date). During the cure period, the failure to
cure the payment default is not an Event of Default (but no Credit Extension will be made during the cure period); 
 8.2 Covenant
Default. 
 (a) Borrower fails or neglects to perform any obligation in Sections 6.2, 6.3, 6.4, 6.6, 6.8, or 6.9, or
violates any covenant in Section 7; or 
 (b) Borrower fails or neglects to perform, keep, or observe, in any material
respect, any other term, provision, condition, covenant or agreement contained in this Agreement or any Loan Documents, and as to any default (other than those specified in this Section 8) under such other term, provision, condition, covenant
or agreement that can be cured, has failed to cure the default within ten (10) days after the occurrence thereof; provided, however, that if the default cannot by its nature be cured within the ten (10) day period or cannot after diligent
attempts by Borrower be cured within such ten (10) day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional period (which shall not in any case exceed thirty (30) days) to attempt
to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an Event of Default (but no Credit Extensions shall be made during such cure period). Grace periods provided under this section shall
not apply, among other things, to financial covenants or any other covenants set forth in subsection (a) above; 
 8.3 Material
Adverse Change. A Material Adverse Change occurs; 
 8.4 Attachment; Levy; Restraint on Business. (a) (i) The service of
process seeking to attach, by trustee or similar process, any funds of Borrower or of any Material Domestic Subsidiary on deposit with Bank or any Bank Affiliate, or (ii) a notice of lien, levy, or assessment is filed against any of
Borrower’s assets by any government agency, and the same under subclauses (i) and (ii) hereof are not, within ten (10) days after the occurrence thereof, discharged or stayed (whether through the posting of a bond or otherwise);
provided, however, no Credit Extensions shall be made during any ten (10) day cure period; and (b) (i) any material portion of Borrower’s assets is attached, seized, levied on, or comes into possession of a trustee or receiver,
or (ii) any court order enjoins, restrains, or prevents Borrower from conducting any part of its business; 
 8.5 Insolvency.
(a) Borrower is unable to pay its debts (including trade debts) as they become due or otherwise becomes insolvent; (b) Borrower commences an Insolvency Proceeding in respect of Borrower as debtor or debtor-in-possession; or (c) an
Insolvency Proceeding is commenced against Borrower as debtor or debtor-in-possession and not dismissed or stayed within forty-five (45) days (but no Credit Extensions shall be made while of any of the conditions described in clause
(a) exist and/or until any Insolvency Proceeding is dismissed); 
 8.6 Other Agreements. There is a default in any agreement to
which Borrower or any Material Guarantor is a party with a third party or parties resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of $250,000 or
that could result in a Material Adverse Change with respect to Borrower or any Material Guarantor; provided, however, that the Event of Default under this Section 8.6 caused by the occurrence of a default under such other agreement shall be
cured or waived for purposes of this Agreement upon Bank receiving written notice from the party asserting such default of such cure or waiver of the default under such other agreement, if at the time of such cure or waiver under such other
agreement (a) Bank has not declared an Event of Default under this Agreement and/or exercised any rights with respect thereto; (b) any such cure or waiver does not result in an Event of Default under any other provision of this Agreement
or any Loan Document; and (c) in connection with any such cure or waiver under such other agreement, the terms of any agreement with such third party are not modified or amended in any manner which could in the good faith judgment of Bank be
materially less advantageous to Borrower or any Material Guarantor; 
  

 20 

 8.7 Judgments. One or more judgments, orders, or decrees for the payment of money in an amount,
individually or in the aggregate, of $250,000 or more (not covered by independent third-party insurance as to which liability has been accepted by such insurance carrier) shall be rendered against Borrower and shall remain unsatisfied, unvacated, or
unstayed for a period of ten (10) days after the entry thereof (provided that no Credit Extensions will be made prior to the satisfaction, vacation, or stay of such judgment, order, or decree); 
 8.8 Misrepresentations. Borrower or any Person acting for Borrower makes any representation, warranty, or other statement now or later in this
Agreement, any Loan Document or in any writing delivered to Bank or to induce Bank to enter this Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect in any material respect when made; 
 8.9 Subordinated Debt. A default or breach occurs under any agreement between Borrower and any creditor of Borrower that signed a subordination,
intercreditor, or other similar agreement with Bank, or any creditor that has signed such an agreement with Bank breaches any terms of such agreement; or 
 8.10 Guaranty. (a) Any guaranty of any Obligations terminates or ceases for any reason to be in full force and effect; (b) any Material Guarantor does not perform any obligation or covenant under any
guaranty of the Obligations; (c) any circumstance described in Sections 8.3, 8.4, 8.5, 8.7, or 8.8. occurs with respect to any Material Guarantor, or (d) the death, liquidation, winding up, or termination of existence of any Guarantor.

 9 BANK’S RIGHTS AND REMEDIES 
 9.1 Rights and Remedies. If an Event of Default has occurred and is continuing, Bank may, without notice or demand, do any one or more or all of the following: 
 (a) declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations
are immediately due and payable without any action by Bank); 
 (b) stop advancing money or extending credit for
Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank; 
 (c) demand that
Borrower (i) deposit cash with Bank in an amount equal to the aggregate amount of any Letters of Credit remaining undrawn, as collateral security for the repayment of any future drawings under such Letters of Credit, and Borrower shall
forthwith deposit and pay such amounts, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of any Letters of Credit; 
 (d) terminate any FX Forward Contracts; 
 (e) demand payment of, and collect any Accounts and General Intangibles comprising Collateral, settle or adjust disputes and claims directly with Account Debtors for amounts, on terms, and in any order that Bank
considers advisable, notify any Account Debtor or other Person owing Borrower money of Bank’s security interest in such funds, verify the amount of the same and collect the same; 
 (f) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the
Collateral. Borrower shall assemble the Collateral if Bank requests and make it available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase,
contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s
rights or remedies; 
 (g) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any
amount held by Bank owing to or for the credit or the account of Borrower; 
  

 21 

 (h) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise
for sale, and sell the Collateral. Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s premises, vehicles, hoists, lifts, cranes, and other Equipment and all other property, including
Borrower’s labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of,
advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; 
 (i) place a “hold” on any account maintained with Bank and/or deliver a notice of exclusive control, any entitlement order, or
other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral; 
 (j) demand and receive possession of Borrower’s Books; and 
 (k) exercise all rights and remedies available to
Bank under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof). 
 9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse
Borrower’s name on any checks or other forms of payment or security; (b) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the
Accounts directly with Account Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance,
security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Bank or a third party as the Code
permits. Borrower hereby appoints Bank as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Bank’s security interest in the Collateral regardless of whether an Event of
Default has occurred until all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied in full and Bank is under no further
obligation to make Credit Extensions hereunder. Bank’s foregoing appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate
indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates. 
 9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.7 or fails to pay any premium thereon or fails to
pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Bank may obtain such insurance or make such payment, and all amounts so paid by Bank are Bank Expenses and immediately due and payable, bearing
interest at the then highest applicable rate, and secured by the Collateral. Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No
payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 
 9.4
Application of Payments and Proceeds. Borrower shall have no right to specify the order or the accounts to which Bank shall allocate or apply any payments required to be made by Borrower to Bank or otherwise received by Bank under this Agreement
when any such allocation or application is not specified elsewhere in this Agreement. If an Event of Default has occurred and is continuing, Bank may apply any funds in its possession, whether from Borrower account balances, payments, proceeds
realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower by credit to the
Designated Deposit Account or to other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit
transaction with any purchaser at any sale of Collateral, Bank shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the
actual receipt by Bank of cash therefor. 
  

 22 

 9.5 Bank’s Liability for Collateral. So long as Bank complies with Bank’s obligations
(as a secured party), if any, under the Code, and reasonable banking practices, regarding the safekeeping of the Collateral in the possession or under the control of Bank, Bank shall not be liable or responsible for: (a) the safekeeping of the
Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or
destruction of the Collateral. 
 9.6 No Waiver; Remedies Cumulative. Bank’s failure, at any time or times, to require strict
performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be
effective unless signed by Bank and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Bank has all rights and
remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a
waiver, election, or acquiescence. 
 9.7 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment and
nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.

 11 CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE. 
 California law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of
the State and Federal courts in Santa Clara County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction to realize on the
Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Bank. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and
Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court.
Borrower hereby waives personal service of the summons, complaints, and other process issued in such 

  

 23 

 
action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at
the address set forth in Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage
prepaid. 
 TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH
PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT
TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a
private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior Court) appointed in accordance with California Code of Civil Procedure Section 638 (or pursuant to

 Exhibit 10.10 
 EXECUTION COPY 
 AMENDED AND RESTATED EMPLOYMENT 
 AND NON-COMPETITION AGREEMENT 
 AMENDED AND RESTATED EMPLOYMENT AND NON-COMPETITION AGREEMENT (this “Agreement”) dated as of December 16, 2008 (the “Effective Date”), by and among EXLSERVICE HOLDINGS, INC., a Delaware
corporation (“Holdings” or the “Company”, and together with any subsidiaries of Holdings, the “Companies”), and Vikram Talwar (the “Executive”). 
 W I T N E S S E T H : 
 A. The
Companies and Executive are currently parties to an Employment and Non-Competition Agreement dated as of September 30, 2006 (the “Current Employment Agreement”). 
 B. The Company desires to continue to employ Executive, and Executive is willing to continue to be employed by the Company, on the terms and conditions
set forth in this Agreement, which amends and restates the Current Employment Agreement to reflect Executive’s new title and responsibilities, effective as of the Effective Date. 
 C. Executive acknowledges that (i) Executive’s continued employment with the Company will provide Executive with trade secrets of and
confidential information concerning the Companies and (ii) the covenants contained in this Agreement are essential to protect the business and goodwill of the Companies. 
 Accordingly, in consideration of the premises and the respective covenants and agreements of the parties set forth below, and intending to be legally
bound hereby, the parties agree as follows: 
 Section 1. Employment. The Company hereby continues to employ Executive, and Executive
hereby accepts such continued employment, on the terms and conditions set forth in this Agreement. Executive represents that Executive is not a party to any agreement that restricts Executive’s right or ability to freely carry out
Executive’s duties hereunder. 
 Section 2. Employment Term. Subject to the provisions of Section 7 of this Agreement, this
Agreement shall be effective for a period commencing on the Effective Date and ending on December 31, 2009 (the “Initial Employment Term”); provided, however, that the Initial Employment Term shall be automatically extended for
successive twelve (12) month periods unless, no later than 120 days prior to the expiration of the Initial Employment Term or any extension thereof, either party hereto shall provide written notice to the other party hereto of its or his desire
not to extend the Employment Term hereof (the Initial Employment Term together with any extension shall be referred to hereinafter as the “Employment Term”). 

 Section 3. Duties, Authority, Status and Responsibilities. 
 (a) Executive shall serve as Executive Chairman of the Company, and in such other position as the Board of Directors of the Company (the
“Board”) may from time to time reasonably determine, subject at all times to the direction, supervision and authority of the Board. Executive’s duties shall include such duties as the Board may from time to time reasonably
assign, including (i) acting as a strategic advisor to the Company’s Chief Executive Officer (including for matters related to mergers and acquisitions), (ii) providing senior leadership for the sales and marketing and strategic
account management initiatives of the Company (for the avoidance of doubt, it is understood that these sales and marketing and strategic account management functions report to the Company’s Chief Executive Officer), and (iii) performing
the other duties of the Executive Chairman set forth in the Company’s By-laws. The Company agrees to provide Executive such assistance and work accommodations as are suitable to the character of his positions with the Company and adequate for
the performance of his duties. The Executive shall be based at the Company’s executive offices in India. 
 (b) During
the Employment Term and except as otherwise agreed by the Company, Executive shall devote Executive’s full employable time, attention and best efforts to the business affairs of the Companies (except during vacations or illness) and will not
actively engage in outside activities, whether or not such activity is pursued for gain, profit or other pecuniary advantage unless such activity (and the amount thereof) is approved by the Board. Executive’s list of approved outside activities
with a description of the nature, scope and time commitment for each of such outside activities is attached hereto as Schedule 3(b) (the “Outside Activities”) (it being understood that such approval is based on the
descriptions set forth in Schedule 3(b) and the level of activity and the nature of the activities remains consistent with the description set forth therein). The Board may request Executive to take reasonable steps to terminate an affiliation
with any entity listed on Schedule 3(b) as promptly as practicable, but, in any event, no later than three (3) months after such request (provided, however, if Executive is required to divest any equity securities, Executive shall have
six (6) months from the date of such request to dispose of such securities), if, in the Board’s reasonable determination, Executive’s affiliation with any such entity listed on Schedule 3(b) presents, or would present, a material
harm to the reputation, business or prospects of the Company. Subject to Executive’s election or appointment as such, Executive further agrees to serve (without additional compensation) if so designated by the stockholders of the Companies, as
applicable, during the Employment Term as a director and a member of any committee of the board of directors of any of the Companies. In addition to the other titles and responsibilities described in this Section 3, if requested by the Board,
Executive shall serve (without additional compensation) during the Employment Term as an officer of any of the subsidiaries of the Company. 
  

 2 

 Section 4. Cash Compensation. 
 (a) Subject to paragraph (b) below, during the Employment Term, Executive shall receive an annual base salary (the “Base
Salary”) of FOUR HUNDRED TWENTY THOUSAND AND 00/100 DOLLARS ($420,000) (the “Initial Base Salary”). Notwithstanding the provisions of Section 4(b), the Base Salary shall be reviewed no less frequently than annually
during the Employment Term for increase, if any, in the sole discretion of the compensation committee of the Board (“Compensation Committee”). The Base Salary shall not be decreased at any time, or for any purpose, during the
Employment Term, unless a Company-wide decrease in pay is implemented. In such case, any decrease in the Base Salary shall be no greater, as a percentage of the Base Salary, than the lowest percentage decrease in the base salary of any other member
of the Company’s senior management. The Base Salary shall not be less than the base salary of any other employee of the Company subject to section 16 of the Securities Exchange Act of 1934 (the “Exchange Act”), other than those
who become employed by the Company by means of an acquisition of a corporation or business and become employees of the Company subject to a preexisting employment arrangement. The Base Salary shall be payable in accordance with the customary payroll
practices of the Company for salaried employees. 
 (b) Executive shall have an opportunity to receive an annual cash bonus
equal to 75% of Base Salary at target, with a maximum payment of no greater than 150% of Base Salary. The Compensation Committee shall determine the criteria and thresholds at which the target and maximum bonus shall be earned, as well as the level
of attainment of the bonus criteria below which no bonus shall be earned, and the level of attainment at which a bonus of other than 75% or 150% of Base Salary shall be earned. To the extent there are extraordinary events such as acquisitions or
dispositions, targets will be amended by the Board to reflect those events. Executive shall be paid Executive’s annual cash bonus (if any) when bonuses are paid generally to senior officers of the Company following completion of the audited
financial statements of the Company. Such bonus shall be paid no later than December 31 of the calendar year following the year in which such bonus is earned. In the event the Company becomes subject to Section 162(m) of the Internal
Revenue Code of 1986, as amended, and the Treasury Regulations promulgated thereunder (the “Code”), the Committee may determine to take such action as shall be necessary to preserve the tax deductibility of the bonus. In that event,
this Section 4(b) shall construed as necessary to do so. 
 Section 5. Reimbursement of Expenses. During the Employment Term,
Executive shall be entitled to receive prompt reimbursement for all travel and business expenses reasonably incurred by Executive (in accordance with the policies and procedures established from time to time by the Company) in performing services
hereunder; provided that Executive shall promptly and properly account therefor in accordance with the Company’s expense policy. 
  

 3 

 Section 6. Other Benefits. 
 (a) Benefit Plans, etc. During the Employment Term, Executive shall (i) be able to participate in all employee benefit plans
and programs that are currently made available to the Company’s senior executives generally or to its employees generally, including, without limitation, pension, profit-sharing, savings and other retirement plans or programs, medical, dental,
hospitalization, short-term and long-term disability and life insurance plans or programs, accidental death and dismemberment protection, travel accident insurance, and any other employee welfare benefit plan or program that may be sponsored by the
Company from time to time, whether funded or unfunded, and (ii) receive such additional fringe benefits and perquisites as the Board may, in its sole discretion, from time to time determine; provided, however, that with the
exception of the restricted stock award described in Section 6(h) hereunder, such benefits for Executive shall not include any equity compensation awards during the Initial Employment Term, except as may hereafter be awarded at the discretion
of the Compensation Committee. Nothing in this Agreement shall be construed to require the Company to establish or maintain any such plans, programs, benefits or perquisites. 
 (b) Tax Planning Assistance. The Company shall reimburse Executive up to $12,000 for expenses incurred during the Employment Term
in connection with personal tax and estate planning. 
 (c) Vacations. Executive shall be entitled to four
(4) weeks vacation with pay during each year of the Employment Term. Vacations shall not be taken in a manner which will unreasonably interfere with Executive’s duties hereunder. Executive shall also be entitled to all paid holidays and
personal days given by the Company to its senior executives. 
 (d) Travel. See Schedule 6 attached hereto.

 (e) Transportation. See Schedule 6 attached hereto. 
 (f) Relocation. If Executive relocates his residence at the request of the Company during the Employment Term, the Company shall,
consistent with its relocation policies, as in effect from time to time, reimburse Executive for the cost of relocating himself and his immediate family. Executive also shall be reimbursed for the after-tax costs of maintaining his residence at the
Effective Date subsequent to any such relocation so as to permit Executive to have the same after-tax value as though he were not maintaining said residence; provided that Executive shall use his best efforts to mitigate such costs by either renting
his existing residence for a market rent (in which case the Company’s obligation shall be limited to the costs of maintaining such residence in excess of such rent) or selling such residence at a prevailing market price (in which case the
Company’s obligation shall cease as of and following the closing of such sale). 
 (g) Additional Fringe Benefits.
During the Employment Term, Executive shall be entitled to additional benefits listed on Schedule 6 hereto. 
  

 4 

 (h) Equity Awards. Executive shall be eligible to receive stock option and/or
restricted stock awards annually during the Employment Term. The Compensation Committee shall have the sole discretion to determine the amount and form of any such subsequent award; provided that in making such determination it shall take into
account (i) the grant date value of the 37,500 restricted shares of Series B common stock of Holdings (“Common Stock”) granted to Executive on July 27, 2006 as the “baseline” value for subsequent awards,
(ii) the Company’s performance against budget since the grant date of the immediately preceding equity compensation award to Executive and (iii) any changes in market compensation of similarly situated executives since the grant date
of the immediately preceding equity compensation award to Executive. The definitive terms of each such subsequent equity compensation award shall be set forth in a restricted stock or stock option agreement, as applicable, between Executive and the
Company substantially in the form of Exhibit A or Exhibit B attached hereto, as applicable, except that (i) the vesting shall be on an annual ratable basis over four years commencing on the date of grant of the award,
(ii) the exercise price of a stock option shall be the fair market value of the stock subject to such option on the date of grant and (iii) such terms may be changed by the mutual agreement of Executive and the Company. 
 (i) Timing of Certain Payments. To the extent that any reimbursements pursuant to Sections 5 or 6 are taxable to Executive, any
such reimbursement payment due to Executive shall be paid to Executive as promptly as practicable, and in all events on or before the last day of Executive’s taxable year following the taxable year in which the related expense was incurred. The
reimbursements pursuant to Sections 5 or 6 are not subject to liquidation or exchange for another benefit and the amount of such benefits and reimbursements that Executive receives in one taxable year shall not affect the amount of such benefits or
reimbursements that Executive receives in any other taxable year. 
 Section 7. Termination. The Employment Term and Executive’s
employment hereunder may be terminated under the following circumstances: 
 (a) Death. The Employment Term and
Executive’s employment hereunder shall terminate upon Executive’s death. In that event, Executive’s estate shall be entitled to a lump sum payment in cash equal to the sum of all accrued cash obligations owing to Executive, plus an
amount equal to a pro-rata portion of the projected bonus amount for the year during which the death occurs, as reasonably determined by the Compensation Committee. Following any termination of Executive’s employment hereunder pursuant to this
Section 7(a), other than as set forth in Section 7(g) the Company shall have no further obligation to pay any compensation or provide any benefits, except as expressly set forth herein. 
 (b) Disability. Either Party may terminate Executive’s employment hereunder for Disability.
“Disability” shall mean Executive’s inability, due to physical or mental incapacity, to substantially perform Executive’s duties and responsibilities under this Agreement for a period of 180 consecutive days. In
conjunction with determining Disability for purposes of this Agreement, Executive 

  

 5 

 
hereby (i) consents to any such examinations which are relevant to a determination of whether Executive is mentally and/or physically disabled and
(ii) agrees to furnish such medical information as may be reasonably requested, and to waive any applicable physician-patient privilege that may arise because of such examination. Not more than 30 days following any termination of
Executive’s employment hereunder pursuant to this Section 7(b), the Company shall make a lump sum payment in cash to Executive equal to the sum of all accrued cash obligations owing to Executive, plus an amount equal to a pro-rata portion
of the projected bonus amount for the year during which the Disability occurs. 
 In the event of Executive’s physical or mental
incapacity which the Board reasonably determines is likely to result in a Disability, the Company may temporarily remove Executive’s job title and relieve him of his responsibilities until the time when Executive returns to his employment in
the same capacity as prior to such incapacity or is terminated in accordance with this Section 7(b), and such removal of title shall not constitute the removal of title (as contemplated by clause (B) of Section 7(d)) for the purpose
of determining “Good Reason’ (as defined below). Notwithstanding the foregoing, if Executive resumes his duties within 180 days of such incapacity, his title and position shall be reinstated. 
 (c) Termination for Cause; Voluntary Termination; Expiration of the Employment Term. The Employment Term and
Executive’s employment hereunder may be terminated (i) by the Company for “Cause” (as defined below) by written notice, specifying the grounds for Cause in reasonable detail, and (ii) by Executive “voluntarily”
(that is, other than for Disability or Good Reason in accordance with Section 7(b) or 7(d)). Executive’s employment shall be terminated at the end of the Employment Term following either party hereto giving the other a notice of its or his
desire not to extend the Employment Term in accordance with Section 2. “Cause” shall mean: 
 (A) a final
non-appealable conviction of, or a pleading of no contest to, (i) a crime of moral turpitude which causes serious economic injury or serious injury to the Company’s reputation or (ii) a felony; or 
 (B) fraud, embezzlement, gross negligence, self-dealing, dishonesty or other gross and willful misconduct which has caused serious and
demonstrable injury to the Company; 
 (C) material violation by Executive of any material Company policy; 
 (D) willful and continuing failure to substantially perform Executive’s duties (other than for reason of physical or mental
incapacity) which failure to perform continues beyond fifteen (15) days after a written demand for substantial improvement in Executive’s performance, identifying specifically and in detail the manner in which improvement is sought, is
delivered to Executive by the Company; provided that a failure to achieve performance objectives shall not by itself constitute Cause and no act or failure to act by Executive shall be considered “willful” unless done or failed to be done
by Executive in bad faith and without a reasonable belief that Executive’s actions or omission was in the best interest of the Company; 
  

 6 

 (E) Executive’s failure to reasonably cooperate in an investigation involving the
Company by any governmental authority; 
 (F) Executive’s material, knowing and intentional failure to comply with
applicable laws with respect to the execution of the Company’s business operations, including, without limitation, a knowing and intentional failure to comply with the Prevention of Corruption Act of India, 1988, or the United States Foreign
Corrupt Practices Act of 1977, as amended; provided, that, if all of the following conditions exist, there will be a presumption that Executive has acted in accordance with such applicable laws: Executive is following, in good faith, the written
advice of counsel, such counsel having been approved by the Board as outside counsel to the Company for regulatory and compliance matters, in the form of a legal memorandum or a written legal opinion, and Executive has, in good faith, provided to
such counsel all accurate and truthful facts necessary for such counsel to render such legal memorandum or written legal opinion; 
 (G) Executive’s failure to follow the lawful directives of the Board which is not remedied within fifteen (15) days after Executive’s receipt of written notice from the Company specifying such failure; 
 (H) Executive’s use of alcohol or drugs which materially interferes with the performance of his duties; or 
 (I) Executive’s failure to take the reasonable steps necessary to terminate his affiliation with any entity listed on
Schedule 3(b) within six months after being requested by the Board, pursuant to Section 3(b) hereof, to take such action. 
 Following any
termination or expiration of the Employment Term and Executive’s employment hereunder pursuant to this Section 7(c), other than as set forth in Section 7(g) Executive shall not be entitled to receive any further compensation or
payments under the Agreement (except for Base Salary relating to Executive’s services prior to the termination date). 
 (d) Termination for Good Reason or Without Cause. The Employment Term and Executive’s employment hereunder may be terminated (i) by Executive for Good Reason and (ii) by the Company “Without Cause” (that is,
other than for Disability or Cause in accordance with Section 7(b) or 7(c)). “Good Reason” shall mean the occurrence, without Executive’s prior written consent, of any of the following events: 
 (A) a substantial reduction of Executive’s duties or responsibilities, or Executive being required to report to any person other than
the Board, provided that, if there is a “Change of Control” (as defined below) and Executive retains similar title and similar authority with the Company or any entity that acquires the Company (or any affiliate or subsidiary of such
entity) following such Change of Control, the parties agree that any change in the title of Executive shall not constitute a significant reduction of Executive’s duties and authorities hereunder; 
  

 7 

 (B) Executive’s job title as an officer of the Company is adversely changed,
provided that if there is a Change of Control and Executive retains similar title and similar authority with the Company or any entity that acquires the Company (or any affiliate or subsidiary of such entity) following such Change of Control, the
parties agree that any change in the title of Executive shall not constitute a significant reduction of Executive’s duties and authorities hereunder; 
 (C) a reduction of Executive’s then Base Salary or annual cash bonus opportunity to below 75% of Base Salary at target other than that described in Section 4(a); 
 (D) a change in the office or location where Executive is based on the Effective Date of more than thirty (30) miles, which new
location is more than thirty (30) miles from Executive’s primary residence; or 
 (E) a breach by the Company of any
material term of the Employment Agreement; 
 provided that, a termination by Executive with Good Reason shall be effective only if, within 30 days following
Executive’s first becoming aware of the circumstances giving rise to Good Reason, Executive delivers a “Notice of Termination” (as defined in Section 7(i)) for Good Reason by Executive to the Company, and the Company within 15
days following its receipt of such notification has failed to cure the circumstances giving rise to Good Reason. 
 (e)
Severance. If Executive’s employment hereunder is terminated pursuant to Section 7(d) hereof, Executive will be entitled to: 
 (i) 24 months of Base Salary plus payment of Executive’s actual bonus earned for year of termination as determined in accordance with the Company’s annual incentive plan as if Executive had been employed for
the full year in which Executive terminates, such Base Salary to be paid ratably for 24 months in accordance with Company’s existing payroll practices (such payment to begin as soon as practicable, and in all events within 30 days following
termination of employment) and such actual bonus, if any, to be paid ratably over the remaining period and number of Base Salary payments hereunder, commencing after the Compensation Committee has determined such bonus amount (such payment to begin
as soon as practicable, and in all events within 30 days following the determination of the bonus amount), provided that if amounts paid under this Section 7(e) are determined to be “deferred compensation” within the meaning of
Section 409A of the Code (“Section 409A”)and Executive is deemed to be a “specified employee” as defined 

  

 8 

 
in Section 409A(a)(2)(B)(i) of the Code and the regulations issued thereunder relating to deferred compensation, then any payments due hereunder in
respect of the six months immediately following Executive’s termination of employment shall be paid in a single lump sum on the Company’s first regularly scheduled pay date occurring more than six months following Executive’s
termination of employment; 
 (ii) continuation of life insurance coverage provided pursuant to Section 6(a) for the
eighteen (18) month period following termination of employment so long as such continuation of coverage is permitted under the Company’s benefit plans and applicable law; provided, that, such coverage shall terminate if
Executive commences employment with a subsequent employer within the applicable period; and 
 (iii) the benefits set forth in
Section 7(g). 
 (f) Termination Following a Change of Control. Notwithstanding anything in this Section 7 to
the contrary, if Executive’s employment is involuntarily terminated by the Company without Cause or Executive terminates employment for Good Reason within 12 months following a Change of Control, then Executive shall receive, in complete
satisfaction of all payments (including severance) due under this Agreement, (i) Base Salary relating to Executive’s services prior to the termination date and (ii) a lump sum payment of $999,000. The payments referred to in
subclauses (i) and (ii) of this Section 7(f) shall be paid as soon as practicable, and in all events within thirty (30) days following termination of employment; provided that if the Change of Control does not satisfy the
definition of a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation pursuant to Section 409A, then the payment referred to in subclause (ii) of
this Section 7(f) will be paid ratably for 24 months in accordance with Company’s existing payroll practices, such payment to begin as soon as practicable, and in all events within 30 days following termination of employment; provided,
further, that if amounts paid under this Section 7(f) are determined to be “deferred compensation” within the meaning of Section 409A and Executive is deemed to be a “specified employee” as defined in
Section 409A(a)(2)(B)(i) of the Code and the regulations issued thereunder relating to deferred compensation, then the payment referred to in subclause (i) of this Section 7(f) and the first of the ratable payments referred to in
subclause (ii) of this Section 7(f) shall be paid on the Company’s first regularly scheduled pay date occurring more than six months following Executive’s termination of employment (the remainder of the ratable payments referred
to in subclause (ii) to continue to be paid ratably in accordance with such subclause). In addition, upon a termination of employment described in this Section 7(f), (iii) Executive shall receive the benefits set forth in
Section 7(g) and (iv) all unvested equity awards granted on or after the Effective Date and held by Executive shall become fully vested and, in the case of stock options, exercisable. 
  

 9 

 (g) Post-Termination Health Insurance. Upon the cessation of Executive’s
employment hereunder for any reason other than termination by the Company for Cause or a voluntary termination by Executive (in each case under Section 7(c)), the Company shall pay on behalf of Executive and his eligible dependents the cost of
continued coverage under the Company’s group health plan for eighteen (18) months following such cessation in accordance with the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), subject to such persons
making timely elections to continue such coverage pursuant to COBRA and satisfaction of COBRA’s eligibility requirements and other terms, conditions, restrictions and exclusions. Should COBRA coverage become unavailable due to the
Company’s failure to maintain a group health plan, the Company shall reimburse Executive and his dependents for the premium cost of comparable coverage obtained directly by Executive and his dependents for the balance of the 18 month period.
The Company’s obligation to pay such premium costs shall cease at the time Executive (or, in the case of Executive’s death, his eligible dependents) become eligible for comparable health benefits from another employer. For purposes of
clarity, it is understood that the preceding two sentences shall apply if Executive’s employment ceases upon the natural expiration of the Employment Term as described in Section 2. In addition, if Executive elects COBRA coverage following
the cessation of his employment for any reason whatsoever (whether paid by the Company or Executive), the Company will, at the request of Executive, facilitate and use commercially reasonable efforts to cause the conversion of his Company group
health insurance coverage to an individual policy upon the expiration of Executive’s eligibility for COBRA coverage; provided that the foregoing is not intended to be a guarantee by the Company that such conversion will be available to
Executive at that time. Any payment made to Executive under Section 7(e)(ii) or under this Section 7(g) (to the extent such payments are treated as “deferred compensation” within the meaning of Section 409A) shall be paid as
soon as practicable following submission of the claims but in any event not later than the third calendar year following the calendar year in which Executive’s “separation from service” (as defined in Section 409A) occurs.

 (h) As used in this Agreement, “Change of Control” means 
 (i) the acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act (a
“Person”) of beneficial ownership (within the meaning of Rule 13d 3 promulgated under the Exchange Act) of more than 50% (on a fully diluted basis) of either (A) the then outstanding shares of Common Stock, taking into account
as outstanding for this purpose such Common Stock issuable upon the exercise of options or warrants, the conversion of convertible stock or debt, and the exercise of any similar right to acquire such Common Stock (the “Outstanding Company
Common Stock”) or (B) the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided,
however, that for purposes of this Plan, the following acquisitions shall not constitute a Change of Control: (I) any acquisition by the Company or (i) any entity that directly or indirectly is controlled by, controls or is under common
control with the Company and (ii) to the extent provided by the Compensation Committee, any entity in which the Company has a significant equity interest (“Affiliate”) on the Effective Date, (II) any 

  

 10 

 
acquisition by any employee benefit plan sponsored or maintained by the Company or any Affiliate, (III) any acquisition by one or more of Oak Hill Partners
L.P., FTVenture, any affiliate of either of them, or any group of which either of them is a member (a “Designated Holder”) , (IV) any acquisition which complies with clauses (A), (B) and (C) of subsection (v) of this
Section 7(h), or (V) in respect of an Award held by a particular Participant, any acquisition by the Participant or any group of persons including the Participant (or any entity controlled by the Participant or any group of persons
including the Participant); 
 (ii) individuals who, on the date hereof, constitute the Board (the “Incumbent
Directors”) cease for any reason to constitute at least a majority of the Board, provided that any person becoming a director subsequent to the date hereof, whose election or nomination for election was approved by a vote of at least
two-thirds of the Incumbent Directors then on the Board (either by a specific vote or by approval of a registration statement of the Company describing such person’s inclusion on the Board, or a proxy statement of the Company in which such
person is named as a nominee for director, without written objection to such nomination) shall be an Incumbent Director; provided, however, that no individual initially elected or nominated as a director of the Company as a result of an actual or
threatened election contest with respect to directors or as a result of any other actual or threatened solicitation of proxies or consents by or on behalf of any person other than the Board shall be deemed to be an Incumbent Director; 
 (iii) the dissolution or liquidation of the Company; 
 (iv) the sale, transfer or other disposition of all or substantially all of the business or assets of the Company; or 
 (v) the consummation of a reorganization, recapitalization, merger, consolidation, statutory share exchange or similar form of corporate
transaction involving the Company that requires the approval of the Company’s stockholders, whether for such transaction or the issuance of securities in the transaction (a “Business Combination”), unless immediately following
such Business Combination: (A) more than 50% of the total voting power of (x) the entity resulting from such Business Combination (the “Surviving Company”), or (y) if applicable, the ultimate parent entity that
directly or indirectly has beneficial ownership of sufficient voting securities eligible to elect a majority of the members of the board of directors (or the analogous governing body) of the Surviving Company (the “Parent Company”),
is represented by the Outstanding Company Voting Securities that were outstanding immediately prior to such Business Combination (or, if applicable, is represented by shares into which the Outstanding Company Voting Securities were converted
pursuant to such Business Combination), and 

  

 11 

 
such voting power among the holders thereof is in substantially the same proportion as the voting power of the Outstanding Company Voting Securities among
the holders thereof immediately prior to the Business Combination, (B) no Person (other than any employee benefit plan sponsored or maintained by the Surviving Company or the Parent Company, or one or more Designated Holders), is or becomes the
beneficial owner, directly or indirectly, of more than 50% of the total voting power of the outstanding voting securities eligible to elect members of the board of directors of the Parent Company (or the analogous governing body) (or, if there is no
Parent Company, the Surviving Company) and (C) at least a majority of the members of the board of directors (or the analogous governing body) of the Parent Company (or, if there is no Parent Company, the Surviving Company) following the
consummation of the Business Combination were Board members at the time of the Board’s approval of the execution of the initial agreement providing for such Business Combination. 
 (i) Notice of Termination. No termination of Executive’s employment by the Company or by Executive (other than Termination
pursuant to Section 7(a)) shall be effective until written notice of termination (the “Notice of Termination”) has been given to the other Party hereto in accordance with Section 8. In the case of a termination by the
Company without Cause, such notice shall be given not less than fifteen (15) business days prior to the termination date. If the Board concludes it is prepared to immediately terminate Executive for Cause (other than due to the conviction of
Executive of a felony), the Board shall put Executive on a leave of absence during which time Executive will forfeit his title and responsibilities but will be provided with an opportunity to appear before the Board, at Executive’s election, to
present arguments and evidence on his own behalf, at a date and time specified in the Notice of Termination. Following such hearing, the Board, by an affirmative vote of a majority of its members (not to include Executive if Executive is a member of
the Board), shall make a final determination that the action or inaction by Executive specified in the Notice of Termination constitutes or does not constitute termination for Cause. If the Board determines that Executive is not terminated for
Cause, the Board shall take any reasonable steps necessary to reinstate Executive in his prior position, with the same title and responsibilities that Executive held prior to receiving the Notice of Termination for Cause described herein.

 (j) Date of Termination. “Date of Termination” shall mean (i) if Executive’s employment
is terminated by Executive’s death, the date of Executive’s death, (ii) if Executive’s employment is terminated for Cause in accordance with Section 7(c), the date specified in the Notice of Termination, (iii) if
Executive’s employment is terminated due to the expiration of the Employment Term as described in Section 7(c), the date that the Employment Term expires, and (iv) if Executive’s employment is terminated for any other reason,
fifteen (15) business days after the date on which a Notice of Termination is delivered. 
  

 12 

 Section 8. Notice. All notices or other communications hereunder shall be in writing and shall be

courier, (c) when sent by facsimile if the date of delivery is a business day, or otherwise on the next business day, or (d) on the fifth day following the date of deposit in the United States mail if sent first class, postage prepaid, by

 Section 9. Covenant Not To Compete. 
 (a) Executive acknowledges that the services he is to render to the Company are of a special and unusual character, with a unique value to the Company, the loss of which cannot adequately be compensated by damages or
an action at law. In view of the unique value to the Companies of the services of Executive for which the Company has contracted hereunder, because of the confidential information to be obtained by, or disclosed to, Executive as herein above set
forth, and as a material inducement to the Company to enter into this Agreement and to pay to Executive the compensation stated herein and any additional benefits stated herein, and other good and valuable consideration, Executive covenants and
agrees that during the Employment Term and during the “Non-Competition Period,” as defined below, Executive shall not, directly or indirectly, enter into the employment of, tender consulting or other services to, acquire any interest in
(whether for Executive’s own account as an individual proprietor, or as a partner, associate, stockholder, officer, director, trustee or otherwise), or otherwise participate in any business that competes, directly or indirectly, with any of the
Companies (i) in the same lines of business in the business process outsourcing industry that the Companies are engaged in at the time Executive’s employment is terminated, or 

  

 14 

 
if Executive is an employee of any of the Companies, at the time Executive is accused of being in competition with any of the Companies pursuant to this
Section 9; (ii) in the provision of the business processes provided by the Companies at the time Executive’s employment is terminated, or if Executive is an employee of any of the Companies, at the time Executive is accused of being
in competition with any of the Companies pursuant to this Section 9; (iii) in the provision of business processes that any of the Companies have taken substantial steps to provide to customers at the time Executive’s employment is
terminated, or if Executive is an employee of any of the Companies, at the time Executive is accused of being in competition with any of the Companies pursuant to this Section 9; or (iv) in the provision of business processes that any of
the Companies are in the process of marketing to existing or potential clients that any of the Companies are taking measures to retain as clients of the Companies, at the time Executive’s employment is terminated, or if Executive is an employee
of any of the Companies, at the time Executive is accused of being in competition with any of the Companies pursuant to this Section 9, during the Employment Term. Executive and the Company acknowledge that clauses (ii), (iii) and
(iv) in the immediately preceding sentence shall not be deemed or interpreted to narrow or otherwise limit the scope of clause (i) of such sentence. Notwithstanding the foregoing, in the event Executive voluntarily terminates employment
other than for Good Reason, Executive shall be restricted from engaging in any business processing outsourcing business for one year from the Date of Termination. For purposes of this Section 9, the “Non-Competition Period”
shall be the one year period following Executive’s termination of employment for any reason; provided that, notwithstanding the above, if Executive’s employment is terminated at the end of the Employment Term following the Company’s
giving Executive a notice of its desire not to extend the Employment Term in accordance with Section 2, the Non-Competition Period, and this Section 9(a), shall not apply following such termination of employment, unless, in the sole
discretion of the Company, the Company continues to pay Executive the Base Salary in effect at the time of termination for one year following termination. 
 (b) Notwithstanding the foregoing, nothing in this Agreement shall prevent (A) the purchase or ownership by Executive of up to two percent (2%) in the aggregate of any class of securities of any entity if
such securities (i) are listed on a national securities exchange or (ii) are registered under Section 12(g) of the Exchange Act; or (B) the direct or indirect ownership of securities of a private company, provided
that, Executive is only a passive investor in such company (having no role, duty or responsibility whatsoever in the management, operations or direction of such company) and owns no more than five percent (5%) in the aggregate of any
securities of such company. If Executive’s employment with the Company is terminated for any reason, and after such termination Executive wishes to take any action, including without limitation, taking a position with another company, which
action could potentially be deemed a violation of this Section 9, Executive shall have the right, after providing the Board with all relevant information, to request a consent to such action from the Board which consent shall not be
unreasonably withheld. The Board shall respond to Executive’s request by granting or denying such consent within not more than 30 calendar days from the date the Company receives written notice of such request from Executive. If Executive
disagrees with the Board’s decision relating to the consent, then a third-party arbitrator (the “Arbitrator”) shall be appointed within five (5) days of the 

  

 15 

 
date Executive notifies the Company of his disagreement, and the third party Arbitrator shall be instructed to make a determination with respect to whether
Executive’s action would constitute a legally valid and enforceable violation of Section 9 within not more than thirty (30) days of his appointment and such determination shall be binding on all of the parties hereto. The cost of the
Arbitrator shall be borne by the Company; provided, however, if the Arbitrator’s determination is inconsistent with Executive’s position, then the cost of the Arbitrator shall be borne by Executive. 
 Section 10. Confidential Information. 
 (a) Protection of Confidential Information. Executive acknowledges that the Companies have a legitimate and continuing proprietary interest in the protection of their confidential information and that they have
invested substantial sums and will continue to invest substantial sums to develop, maintain and protect such confidential information. During the Employment Term and at all times thereafter, Executive shall not, except with the written consent of
the Company or in connection with carrying out Executive’s duties or responsibilities hereunder, furnish or make accessible to anyone or use for Executive’s own benefit any trade secrets, confidential or proprietary information of any of
the Companies, including their business plans, marketing plans, strategies, systems, programs, methods, employee lists, computer programs, insurance profiles and client lists; provided, however, that such protected information shall
not include either information required to be disclosed under law or pursuant to an order of a court, governmental agency, arbitration panel or other person or body with apparent jurisdiction or information known to the public or otherwise in the
public domain without violation by Executive of this Section 10. 
 (b) Property of the Company. All memoranda,
notes, lists, records and other documents or papers (and all copies thereof) relating to the Companies, whether written or stored on electronic media, made or compiled by or on behalf of Executive in the course of Executive’s employment, or
made available to Executive in the course of Executive’s employment, relating to any of the Companies, or to any entity which may hereafter become an affiliate thereof, but excluding Executive’s personal effects, rolodexes and similar
items, shall be the property of the Company, and shall, except as otherwise agreed by the Company, be delivered to the Company promptly upon the Termination of Executive’s employment with the Company or at any other time upon request.

 Section 11. Non-Disparagement; Non-Solicit. 
 (a) During the Employment Term and for a period of one (1) year thereafter Executive shall make no unfavorable, disparaging or
negative comment, remark or statement, whether written or oral (a “Disparaging Statement”), about the Company or any of its affiliates, officers, directors, shareholders, consultants, or employees; provided that he may give truthful
testimony before a court, governmental agency, arbitration panel, or similar person or body with apparent jurisdiction and may discuss such matters in confidence with Executive’s attorney(s) and other professional advisors. During the foregoing
period, the Company and its officers and directors (acting 

  

 16 

 
in their capacity as officers and directors of the Company) shall make no Disparaging Statement about Executive; provided that any officer or director may
give truthful testimony before a court, governmental agency, arbitration panel, or similar person or body with apparent jurisdiction and may discuss such matters in confidence with their or the Company’s attorney(s) and other professional
advisors. 
 (b) For one year following termination of Executive’s employment (i) Executive may not solicit,
encourage, or induce or attempt to solicit, encourage, or induce any (A) current employee, marketing agent, or consultant of any of the Companies to terminate his or her employment, agency, or consultancy with any of the Companies or any
(B) prospective employee with whom the Company has had discussions or negotiations within six months prior to Executive’s termination of employment not to establish a relationship with any of the Companies, (ii) induce or attempt to
induce any current customer to terminate its relationship with any of the Companies or (iii) induce any potential customer with whom the Company has had discussions or negotiations within six months prior to Executive’s termination of

 Section 12. Miscellaneous.

liability under the laws of the State of Delaware applicable to corporations and as such Executive shall not, nor shall he have the right to, make any claim against the shareholders of Holdings relating to any contest or dispute under this
Agreement. 
 (c) Waiver. No provision of this Agreement may be modified, waived or discharged unless such waiver,
modification or discharge is agreed to in a writing signed by Executive and an officer of the Company (other than Executive) duly authorized by the Board to execute such amendment, waiver or discharge. No waiver by either party to this Agreement at
any time of any breach of the other party of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior
or subsequent time. 
 (d) Successors and Assigns. This Agreement shall be binding on and inure to the benefit of the
successors and assigns of the Company. 
 (e) Governing Law. The validity, interpretation, construction and performance
of this Agreement shall be governed by the laws of the State of New York, without regard to the conflict of laws principles of such State which could cause the application of the laws of any other state. 
  

 17 

 (f) Consent to Jurisdiction and Service of Process. Any claim for
injunctive relief pursuant to Sections 9, 10, 11 or 12(k) under this Agreement shall be instituted exclusively in any Federal court of the Southern District of New York or any state court located in New York County, State of New York, and each
party agrees not to assert, by way of motion, as a defense or otherwise, in any such claim, any claim that it is not subject personally to the jurisdiction of such court, that the claim is brought in an inconvenient forum, that the venue of the
claim is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. Each party further irrevocably submits to the jurisdiction of such court in any such claim. Any and all service of process and any other
notice in any such claim shall be effective against any party if given personally or by registered or certified mail, return receipt requested, or by any other means of mail that requires a signed receipt, postage prepaid, mailed to such party as
herein provided. Nothing herein contained shall be deemed to affect the right of any party to serve process in any manner permitted by law or to commence legal proceedings or otherwise proceed against any other party in any other jurisdiction.

 (g) Dispute Resolution. Any dispute, controversy or other claim, other than claims solely for injunctive relief
pursuant to Section 9, 10, 11 or 12(k), arising out of or relating to (i) this Agreement, or (ii) Executive’s employment with the Company shall be resolved by binding confidential arbitration, to be held in New York, New York in
accordance with the Commercial Arbitration Rules of the American Arbitration Association. Judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. Executive agrees that it shall not bring any
claim or action against the Company’s directors, officers or shareholders and shall not be entitled to any punitive, special or consequential damages in connection with any such claim, dispute or controversy. In connection with any claim or
action brought by any of the Companies or any of their respective directors or, officers or shareholders against Executive, no such person shall be entitled to any punitive, special or consequential damages. 
 (h) Assignment. This Agreement is a personal contract, and the rights and interests of Executive hereunder may not, during the
Employment Term, be sold, transferred, assigned, pledged or hypothecated. This Agreement may not be assigned by the Company other than to a company (i) which, directly or indirectly controls, is controlled by or is under common control with the
Company, or which is a successor in interest to substantially all of the business operations of the Company, and (ii) which assumes in writing or by operation of law, at the time of the assignment, the Company’s obligation to perform this
Agreement; and (iii) which has sufficient capitalization to enable it to meet its assumed obligation to perform this Agreement. 
 (i) Severability of Invalid or Unenforceable Provisions. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement,
which shall remain in full force and effect. 
  

 18 

 (j) Counterparts. This Agreement may be executed in one or more counterparts, each
of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 
 (k)
Injunctive Relief; Damages. Executive acknowledges that damages for any breach of Sections 9 through 11 of this Agreement may be difficult to determine and inadequate to remedy the harm which may be caused and, therefore, consents that
such Sections may be enforced by temporary or permanent injunction. Such injunctive relief shall be in addition to and not in place of any other remedies available at law or equity, including damages. Should any court or tribunal decline to enforce
such sections of this Agreement on the basis that such provisions are overly restrictive of activities of Executive as to time, scope or geography, such provisions shall be deemed to be modified to restrict Executive’s activities to the maximum
extent of time, scope and geography which such court or tribunal shall find enforceable, and such provisions shall be so enforced. 
 (l) Entire Agreement. This Agreement sets forth the entire agreement of the Companies and Executive in respect of the subject matter contained herein and supersedes all prior agreements (including, but not limited to, the Current
Employment Agreement as in effect prior to the Effective Date), promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by any officer, employee or representative of either party to this Agreement
hereto and any prior agreement of the parties hereto in respect of the subject matter contained herein. 
 (m)
Beneficiaries/References. Executive shall be entitled, to the extent permitted under any applicable law, to select and change a beneficiary or beneficiaries to receive any compensation or benefit hereunder following Executive’s death by
giving the Company written notice thereof. In the event of Executive’s death or a judicial determination of Executive’s incompetence, reference in this Agreement to Executive shall be deemed, where appropriate, to refer to Executive’s
beneficiary, estate or other legal representative. 
 (n) Withholding; Tax Equalization. The Company shall be entitled
to withhold from any payment due to Executive hereunder any amounts required to be withheld by applicable tax laws or regulations. The Company shall provide Executive such additional compensation, if any, as is reasonably necessary to ensure that
Executive’s total compensation, benefits and bonus payments have the same after-tax value as if Executive were employed in and subject to taxation only in the United States; provided, that, as Executive has located, at the request of the
Company, from his residence to India, the Company shall reimburse Executive for the amount of the overall increase in his tax liabilities as a result of his relocation to India and the fact that he is subject to Indian taxation. These equalization
payments shall include a tax restoration payment that takes into account the impact of the reimbursements. Executive agrees that if he receives a refund or other credit on his taxes, he shall repay the Company any amount in excess of the amount
necessary such that the after-tax amount retained by Executive is equal to the amount he would have retained had he remained employed in the United States. 
  

 19 

 (o) Registration of Shares. The Company shall, when eligible, register on Form S-8
or such other appropriate form the resale of shares of Common Stock owned by Executive pursuant to the grant or exercise of equity compensation awards held by Executive on the Effective Date or underlying equity compensation awards granted to
Executive during the Employment Term. This is in addition to any registration rights Executive has under any other contract with the Company. 
 (p) Directors’ Slate. Executive’s name shall be included on the Company’s recommended slate of directors for each stockholders meeting during the Employment Term at which Executive is eligible
for reelection to the Board; provided, however, that Executive agrees to consult in good faith with the Board regarding Executive’s continued service on the Board if and to the extent the Board determines that prevailing standards of corporate
governance provide that it is not appropriate for an officer of the Company to serve on the Board. Executive agrees to tender resignation from the Board upon termination of employment. In the case of Executive’s termination for any reason other
than by the Company for Cause, if and only if Executive continues to own 4% of the Common Stock, Executive may, subject to the approval of the Board in its sole reasonable determination, designate an individual to be included on the Company’s
recommended slate of directors for the next stockholders’ meeting at which directors of the Company are to be elected; provided that this sentence shall cease to apply on and following the time that any equity securities of the Company become
listed for trading on a national securities exchange or other quotation or trading system. 
 (q) Legal Fees. Upon the
execution of this Agreement, the Company agrees to pay on behalf of Executive all legal fees and expenses incurred by Executive in connection with the negotiation, drafting, and execution of this Agreement which, when aggregated with any similar
fees incurred by Rohit Kapoor and paid by the Company in connection with the negotiation, drafting and execution of an employment agreement for Mr. Kapoor with the Company, do not exceed $25,000. 
 (r) Indemnification. The Company shall indemnify and defend Executive to the fullest extent permitted by the law of the State of
Company’s incorporation and the By-Laws and Certificate of Incorporation of the Company with respect to any claims that may be brought against Executive arising out of any action taken or not taken in Executive’s capacity as an officer or
director of the Company; provided, that, the Company shall not indemnify and defend Executive with respect to any claims brought against Executive relating to intentional or willful acts of the Executive, or to other acts as to which
indemnification is not allowable under applicable law. In addition, Executive shall be covered, in respect of Executive’s activities as an officer or director of the Company, by the Company’s Directors and Officer liability policy or other
comparable policies obtained by the Company’s successors, to the fullest extent permitted by such policies. Notwithstanding the foregoing, the Company’s responsibilities under this Section 12(r) shall not apply to any claims raised
against Executive after the sixth anniversary of his termination of employment. It is intended that any indemnification payment or advancement of expenses made hereunder shall be exempt from Section 409A. Notwithstanding the foregoing, if any
indemnification payment or advancement of expenses made hereunder shall be determined to be “deferred 

  

 20 

 
compensation” within the meaning of Section 409A, then (i) the amount of the indemnification payment or advancement of expenses during one
taxable year shall not affect the amount of the indemnification payments or advancement of expenses during any other taxable year, (ii) the indemnification payments or advancement of expenses must be made on or before the last day of
Executive’s taxable year following the year in which the expense was incurred, and (iii) the right to indemnification payments or advancement of expenses hereunder is not subject to liquidation or exchange for another benefit. 

(s) Section 409A. 
 (i) The parties intend that any amounts payable hereunder that could constitute “deferred compensation” within the meaning of Section 409A will be compliant with Section 409A. In light of the
uncertainty as of the date hereof with respect to the proper application of Section 409A, the Company and Executive agree to negotiate in good faith to make amendments to this Agreement as the parties mutually agree are necessary or desirable
to avoid the imposition of taxes or penalties under Section 409A. Notwithstanding the foregoing, Executive shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or for the account of
Executive in connection with this Agreement (including any taxes and penalties under Section 409A), and neither the Company nor any affiliate shall have any obligation to indemnify or otherwise hold Executive (or any beneficiary) harmless from
any or all of such taxes or penalties. 
 (ii) Notwithstanding anything in this Agreement to the contrary, in the event that
Executive is deemed to be a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) and Executive is not “disabled” within the meaning of Section 409A(a)(2)(C), no payments hereunder that are “deferred
compensation” subject to Section 409A shall be made to Executive prior to the date that is six (6) months after the date of Executive’s “separation from service” (as defined in Section 409A) or, if earlier,
Executive’s date of death. Following any applicable six (6) month delay, all such delayed payments will be paid in a single lump sum on the earliest permissible payment date. For purposes of Section 409A, each of the payments that may
be made under Section 4(c)(i) are designated as separate payments for purposes of Treasury Regulations Section 1.409A-1(b)(4)(i)(F), 1.409A-1(b)(9)(iii) and 1.409A-1(b)(9)(v)(B). 
 (iii) For purposes of this Agreement, with respect to payments of any amounts that are considered to be “deferred compensation”
subject to Section 409A, references to “termination of employment” (and substantially similar phrases) shall be interpreted and applied in a manner that is consistent with the requirements of Section 409A.
