 Exhibit 10.16 
  
 LOAN AND SECURITY AGREEMENT 
  

THIS LOAN AND SECURITY AGREEMENT (together with any schedule, annex, or exhibit attached hereto, as the same may be amended, restated, or
otherwise modified, this “Agreement”) is entered into on March 10, 2004 (the “Effective Date”) between SILICON VALLEY BANK (“Bank”), whose address is 3003 Tasman Drive, Santa Clara, California
95054, and REDBACK NETWORKS INC., a Delaware corporation (“Borrower”), whose chief executive office is 300 Holger Way, San Jose, California 95134 (“Borrower’s Address”). (Definitions of capitalized terms used
in this Agreement are set forth in Section 8 below.) 
  

	1.	ADVANCES. 

  
 1.1 Advances. Bank will make advances and/or EXIM Loans (collectively, the “Advances”) to Borrower up to the
amounts shown on the Schedule, provided no Default or Event of Default has occurred and is continuing, and subject to deduction of Reserves. 
  
 1.2 EXIM Guaranty. To facilitate the financing of Eligible Foreign Accounts, the EXIM Bank has agreed to guarantee the EXIM
Loans made under this Agreement, pursuant to a Master Guarantee Agreement, Loan Authorization Agreement and (to the extent applicable) Delegated Authority Letter Agreement (collectively, the “EXIM Guaranty”). If, at any time after
the EXIM Guaranty has been entered into by Bank, for any reason other than due to any action or inaction of Borrower under the EXIM Guaranty, (a) the EXIM Guaranty shall cease to be in full force and effect, or (b) if the EXIM Bank declares the EXIM
Guaranty void or revokes any obligations thereunder or denies liability thereunder, and any Overadvance results from either of the foregoing, Bank shall provide notice of such Overadvance to Borrower, and Borrower shall immediately pay the amount of
the excess to Bank. If, at any time after the EXIM Guaranty has been entered into by Bank, for any reason other than the one described in the foregoing sentence, (x) the EXIM Guaranty shall cease to be in full force and effect, or (y) the EXIM Bank
declares the EXIM Guaranty void or revokes any obligations thereunder or denies liability thereunder, 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. 
  
 1.3 EXIM Agreement. Borrower may execute and deliver a Borrower Agreement, in the form specified by the EXIM Bank (attached
hereto as Annex A), in favor of Bank and the EXIM Bank, together with an amendment thereto approved by the EXIM Bank to conform certain terms of such Borrower Agreement to the terms of this Agreement (as amended, the “EXIM
Agreement”). If the EXIM Agreement is entered into by Borrower and the EXIM Bank and delivered to Bank, this Agreement shall be subject to all of the terms and conditions of the EXIM Agreement, all of which are hereby incorporated herein by
this reference. From and after the time Borrower and the EXIM Bank have entered into the EXIM Agreement and delivered the same to Bank, 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 Agreement as though the same were expressly set forth herein. In the event of any conflict between the terms of the EXIM Agreement (if then in effect) and the other terms of this

  

 
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 Agreement. If the EXIM Agreement is entered into by Borrower and the EXIM Bank and delivered to Bank, 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 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 Agreement, including without limitation all facility fees and usage fees, and Bank is authorized to debit any of Borrower’s deposit
accounts with Bank for such fees, costs and expenses when paid by Bank. If Borrower desires to receive advances under the EXIM Borrowing Base, until such time as Borrower and the EXIM Bank have entered into the EXIM Agreement and delivered the same
to Bank, Borrower shall pay the EXIM Borrowing Fee set forth on the Schedule. 
  
 1.4 Interest. All Advances, Bank Expenses, and other fees shall bear interest at the rate shown on the Schedule, except where expressly set forth to the contrary in this Agreement. Interest
shall be payable monthly, in arrears, on the last day of the month. Interest shall be charged to a deposit account with Bank designated by Borrower, or if no funds are available in any such deposit account, as an Advance under this Agreement.

  
 1.5 Overadvances. Subject to the
terms set forth in the Schedule and except as otherwise provided in Section 1.2, if at any time or for any reason the total of all outstanding Advances and all other monetary Obligations exceeds the sum of the Credit Limit and the Permitted
Overadvances (an “Overadvance”), Borrower shall immediately pay the amount of the excess to Bank, without notice or demand. Without limiting Borrower’s obligation to repay to Bank the amount of any Overadvance, Borrower agrees
to pay Bank interest on the outstanding amount of any Overadvance that is not a Permitted Overadvance, on demand, at the Default Rate. 
  
 1.6 Fees. Borrower shall pay Bank the fees shown on the Schedule, which are in addition to all interest and other sums payable
to Bank and are not refundable. 
  
 1.7
Advance Requests. To obtain an Advance, Borrower shall make a request to Bank by facsimile or telephone. Advance requests received after 12:00 Noon Pacific time will not be considered by Bank until the next Business Day. Bank
may rely on any telephone request for a Advance given by a person whom Bank reasonably believes is an authorized representative of Borrower, and Borrower will indemnify Bank for any loss Bank suffers as a result of that reliance. 
  
 1.8 Letters of Credit. At the request of
Borrower, Bank may, in its good faith business judgment, issue or arrange for the issuance of letters of credit for the account of Borrower, in each case in form and substance satisfactory to Bank in its sole discretion (collectively,
“Letters of Credit”). The aggregate face amount of all Letters of Credit from time to time outstanding shall not exceed the Letter of Credit Sublimit shown on the Schedule, and shall be reserved against the Borrowing Base which
would reduce the availability of Advances hereunder, and in the event at any time there is insufficient availability under the Borrowing 

  

 -2- 

 
Base for such reserve, Borrower shall deposit and maintain with Bank cash collateral, or maintain securities acceptable to Bank and subject to a securities
account control agreement, in an amount at all times equal to such deficiency, which shall be held as Collateral for all purposes of this Agreement. Upon Borrower’s request, Bank will release any such deposit to Borrower to the extent there is
additional availability under the Borrowing Base. Borrower shall pay all bank charges (including charges of Bank) for the issuance of Letters of Credit, together with such additional fee as Bank’s letter of credit department shall charge in
connection with the issuance of the Letters of Credit or as set forth in the Standby Letter of Credit Application completed by Borrower. 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. Each Letter of Credit shall have an expiry date no later than thirty days prior to the Maturity Date. Borrower hereby agrees to indemnify and hold Bank harmless from any loss, cost, expense, or liability, including
payments made by Bank, expenses, and reasonable attorneys’ fees incurred by Bank arising out of or in connection with any Letters of Credit; except to the extent any such loss, cost, expense or liability arises from the gross negligence or
willful misconduct of Bank. Borrower 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, except in the case of gross negligence or willful misconduct. Borrower understands that Letters of Credit may require Bank to indemnify the issuing bank for certain
costs or liabilities arising out of claims by Borrower against such issuing bank. Borrower hereby agrees to indemnify and hold Bank harmless with respect to any loss, cost, expense, or liability incurred by Bank under any Letter of Credit as a
result of Bank’s indemnification of any such issuing bank. The provisions of this Agreement, as it pertains to Letters of Credit, and any other Loan Document relating to Letters of Credit are cumulative. To the extent the terms of any letter of
credit application are in conflict with this Agreement, the terms of this Agreement shall control. The Jabil LC is hereby deemed to have been issued hereunder and is expressly made subject to the terms and conditions of this Agreement. 

 
 2.         SECURITY
INTEREST. To secure the payment and performance of all of the Obligations when due, Borrower hereby grants to Bank a security interest in all of the following (collectively, the “Collateral”): all right, title and interest
of Borrower in and to all of the following, whether now owned or hereafter arising or acquired and wherever located: all Accounts; all Inventory; all Equipment; all Deposit Accounts; all General Intangibles (including without limitation all
Intellectual Property); all Investment Property (excluding 35% of the equity interests of Subsidiaries formed in jurisdictions outside of the United States); all Other Property; and any and all claims, rights and interests in any of the above, and
all guaranties and security for any of the above, and all substitutions and replacements for, additions, accessions, attachments, accessories, and improvements to, and proceeds (including proceeds of any insurance policies, proceeds of proceeds and
claims against third parties) of, any and all of the above, and all Borrower’s books relating to any and all of the above.

	3.	REPRESENTATIONS, WARRANTIES AND COVENANTS OF BORROWER. 

  
 In order to induce Bank to enter into this Agreement and to make Advances, and except to the extent set forth in the
Representations, Borrower represents and warrants to Bank as follows, and Borrower covenants that the following representations will continue to be true at all times, and that Borrower will at all times comply with all of the following covenants,
throughout the term of this Agreement and until all Obligations have been paid and performed in full: 
  
 3.1 Corporate Existence and Authority. Borrower is and will continue to be, duly organized, validly existing and in good
standing under the laws of the State of Delaware. Borrower is and will continue to be qualified and licensed to do business in Delaware, California, and all jurisdictions in which any failure to do so would result in a Material Adverse Change. The
execution, delivery and performance by Borrower of this Agreement, and all other documents contemplated hereby (a) have been duly and validly authorized, (b) are enforceable against Borrower in accordance with their terms (except as enforcement may
be limited by equitable principles and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors’ rights generally), (c) do not violate Borrower’s Certificate of Incorporation, or Borrower’s by-laws,
or any law or any material agreement or instrument which is binding upon Borrower or its property, and (d) do not constitute grounds for acceleration of any material indebtedness or obligation under any agreement or instrument which is binding upon
Borrower or its property. 
  
 3.2 Name; Trade
Names and Styles. The name of Borrower set forth in the heading to this Agreement, or such other name of which it has notified Bank in accordance with this Section 3.2, is its correct name. Listed in the Representations are all prior names
of Borrower and all of Borrower’s present and prior trade names. Borrower shall give Bank 30 days prior written notice before changing its name or doing business under any other name. Borrower has complied, and will in the future comply, in all
material respects, with all laws relating to the conduct of business under a fictitious business name, except where the failure to so comply would not reasonably be expected to result in a Material Adverse Change. 
  
 3.3 Place of Business; Location of Collateral.
The address set forth in the heading to this Agreement as Borrower’s address (or such other address of which Borrower has given Bank notice pursuant to this Section 3.3) is Borrower’s chief executive office. In addition, Borrower has
places of business and Collateral is located only at the locations set forth in the Representations (or such other locations of which Borrower has given or will give Bank notice pursuant to this Section 3.3). Borrower will give Bank at least ten
days prior written notice before opening any additional place of business, changing its chief executive office, or moving any of the Collateral to a location other than Borrower’s Address or one of the locations set forth in the
Representations, except that Borrower may maintain sales offices in the ordinary course of business at which not more than a total of $50,000 fair market value of Equipment is located. 
  
 3.4 Title to Collateral; Perfection; Permitted Liens. 
  
 (a) Borrower is now, and will at all times in the future be,
the sole owner of all the Collateral, except for items of Equipment which are leased or licensed to Borrower. The Collateral now is and will remain free and clear of any and all liens, charges, security interests, encumbrances and adverse claims,
except for Permitted Liens. Bank now has, and will continue to have, a first-priority perfected and enforceable security interest in all of the Collateral, subject 

  

 -4- 

 
only to the Permitted Liens, and Borrower will at all times defend Bank and the Collateral against all claims of others. 
  
 (b) Borrower has set forth in the Representations all of
Borrower’s Deposit Accounts. Borrower will give Bank five Business Days advance written notice before establishing any Deposit Account with a bank other than Bank and will cause the institution where any such new Deposit Account is maintained
to execute and deliver to Bank a control agreement in form sufficient to perfect Bank’s security interest in the Deposit Account and otherwise satisfactory to Bank in its good faith business judgment. Nothing herein limits any requirements
which may be set forth in the Schedule as to where Deposit Accounts will be maintained. 
  
 (c) In the event that Borrower shall at any time after the date hereof have any commercial tort claims against others, which it is
asserting, and in which the potential recovery exceeds $100,000, Borrower shall promptly notify Bank thereof in writing and provide Bank with such information regarding the same as Bank shall request (unless providing such information would waive
the Borrower’s attorney-client privilege). Such notification to Bank shall constitute a grant of a security interest in the commercial tort claim and all proceeds thereof to Bank, and Borrower shall execute and deliver all such documents and
take all such actions as Bank shall request in connection therewith. 
  
 (d) None of the Collateral now is or will be affixed to any real property in such a manner, or with such intent, as to become a fixture. Borrower is not and will not become a lessee under any real property lease
pursuant to which the lessor may obtain any rights in any of the Collateral and no such lease now prohibits, restrains, impairs or will prohibit, restrain or impair Borrower’s right to remove any Collateral from the leased premises. Whenever
any Collateral is located upon premises in which any third party has an interest, Borrower shall, whenever requested by Bank, use commercially reasonable efforts to cause such third party to execute and deliver to Bank, in form acceptable to Bank,
such waivers and subordinations as Bank shall specify in its good faith business judgment. In the event that such waivers and subordinations are not obtained, Bank may, in its discretion, establish appropriate reserves against the Borrowing Base.
Borrower will keep in full force and effect, and will comply with all material terms of, any lease of real property where any of the Collateral now or in the future may be located. 
  
 3.5 Maintenance of Collateral. Borrower will maintain the Collateral in good working condition
(ordinary wear and tear excepted), and Borrower will not use the Collateral for any unlawful purpose. Borrower will promptly advise Bank in writing of any material loss or damage to the Collateral. 
  
 3.6 Books and Records. Borrower has maintained
and will maintain at Borrower’s Address books and records sufficient to prepare financial statements in accordance with GAAP. 
  
 3.7 Financial Condition, Statements and Reports. Subject to the absence of footnotes and year-end adjustments in the case of
interim financial statements, all financial statements of Borrower and it consolidated subsidiaries now or in the future delivered to Bank have been, and will be, prepared in conformity with GAAP and now and in the future will fairly 

  

 -5- 

 
present in all material respects the results of operations and financial condition of Borrower and its consolidated subsidiaries, in accordance with GAAP, at
the times and for the periods therein stated. Between the last date covered by any such statement provided to Bank and the date hereof, there has been no Material Adverse Change. 
  
 3.8 Tax Returns and Payments; Pension Contributions. Borrower has timely filed, and will timely
file, all required tax returns and reports, and Borrower has timely paid, and will timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions now or in the future owed by Borrower (it being understood that
payment of certain taxes has been deferred and such taxes will be paid over time pursuant to Borrower’s Plan of Reorganization). Notwithstanding the foregoing, Borrower may, however, defer payment of any contested taxes, provided that Borrower
(a) in good faith contests Borrower’s 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, the
proceedings, and (c) posts bonds or takes any other steps required to keep the contested taxes from becoming a lien upon any of the Collateral. 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 that would result in a Material Adverse Change. Borrower has paid, and shall continue to pay all amounts necessary to fund all present and future pension, profit sharing and
deferred compensation plans in accordance with their terms, and Borrower has not and will not withdraw from participation in, permit partial or complete termination of, or permit 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 that would result in a Material Adverse Change. 

 
 3.9 Compliance with Law. Borrower has, to its
knowledge, complied, and will comply, in all material respects, with all provisions of all foreign, federal, state and local laws and regulations applicable to Borrower, including, but not limited to, those relating to Borrower’s ownership of
real or personal property, the conduct and licensing of Borrower’s business, and all environmental matters. 
  
 3.10 Litigation. There is no claim, suit, litigation, proceeding or investigation pending or (to Borrower’s knowledge)
threatened against Borrower in any court or before any governmental agency which could reasonably be expected to result, either separately or in the aggregate, in any Material Adverse Change. Borrower will promptly inform Bank in writing of any
claim, proceeding, litigation or investigation in the future threatened in writing or instituted against Borrower involving any single claim that can reasonably be expected to result in liability in excess of $100,000, or $250,000 in the aggregate.

  
 3.11 Use of Proceeds. All proceeds
of all Advances shall be used solely for lawful business purposes. Borrower is not purchasing or carrying any “margin stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System) and no part of the proceeds
of any Advance will be used to purchase or carry any “margin stock” or to extend credit to others for the purpose of purchasing or carrying any “margin stock,” in either case in violation of Regulation U. 
  

 -6- 

	4.	ACCOUNTS. 

  
 4.1 Representations Relating to Accounts. Borrower represents and warrants to Bank as follows: Each Account with respect to
which Advances are requested by Borrower shall, on the date each Advance is requested and made (a) represent an undisputed bona fide existing unconditional obligation of the Account Debtor created by the sale, delivery, and acceptance of goods or
the rendition of services, or the non-exclusive licensing of Intellectual Property, in the ordinary course of Borrower’s business, and (b) meet the Minimum Domestic Eligibility Requirements or Minimum Foreign Eligibility Requirements, as the
case may be, set forth in Section 8 below. 
  
 4.2
Representations Relating to Documents and Legal Compliance. Borrower represents and warrants to Bank as follows: All statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing
the Accounts are and shall be true and correct and all such invoices, instruments and other documents and all of Borrower’s books and records are and shall be genuine and in all respects what they purport to be. 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. To Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and
agreements relating to all Accounts are and shall be genuine, and all such documents, instruments and agreements are and shall be legally enforceable in accordance with their terms except to the extent that the enforceability thereof may be limited
by applicable bankruptcy, insolvency, moratorium and other similar laws affecting creditors’ rights generally and by equitable principles (regardless of whether enforcement is sought in equity or at law). 
  
 4.3 Schedules and Documents relating to Accounts.
Borrower shall deliver to Bank transaction reports and schedules of collections, as provided in the Schedule, on Bank’s standard forms; provided, however, that Borrower’s failure to execute and deliver the same shall not affect or limit
Bank’s security interest 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 security interest 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, and Borrower warrants the genuineness of all of the foregoing. Borrower shall also furnish to Bank an aged accounts receivable trial balance as provided in the Schedule. 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. 
  
 4.4 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, to be applied to the
Obligations in such order as Bank shall determine (it being understood that no proceeds will be applied to undrawn amounts of Letters of Credit). Borrower shall deposit all proceeds of 

  

 -7- 

 
Collateral 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. 
  
 4.5 Remittance of Proceeds. All proceeds arising from the disposition of any Collateral shall be delivered, in kind, by Borrower to Bank in the original form in which received by Borrower not later than the
following Business Day after receipt by Borrower, to be applied to the Obligations in such order as Bank shall determine; provided that, if no Default or Event of Default has occurred and is continuing, Borrower shall not be obligated to remit to
Bank the proceeds of the sale of worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $500,000 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. 
  
 4.6 Disputes. Borrower shall notify Bank promptly of all disputes or claims relating to Accounts. Borrower shall not forgive (completely or partially), compromise or settle any Account for
less than payment in full, or agree to do any of the foregoing, except that Borrower may do so, provided that: (a) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, and in arm’s length
transactions, which are reported to Bank on the regular reports provided to Bank; (b) no Default or Event of Default has occurred and is continuing; and (c) taking into account all such discounts, settlements and forgiveness, the total outstanding
Advances will not exceed the Credit Limit (unless arrangements are made to reduce the amount of the outstanding Advances so that they will not exceed the Credit Limit). 
  
 4.7 Returns. Provided no Event of Default has occurred and is continuing, if any Account Debtor
returns any Inventory to Borrower, Borrower shall promptly determine the reason for such return and, unless such return is disputed by Borrower or unless such return is immediately replaced by Borrower, promptly issue a credit memorandum to the
Account Debtor in the appropriate amount. 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. 
  
 4.8
Verification. Bank may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts, by means of mail, telephone or otherwise, either in the name of
Borrower or Bank or such other name as Bank may choose. 
  
 4.9 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. 
  

 -8- 

	5.	ADDITIONAL DUTIES OF BORROWER. 

  
 5.1 Financial and Other Covenants. Borrower shall at all times comply with the financial and other covenants set forth in the
Schedule. 
  
 5.2 Insurance. Borrower
shall, at all times insure all of the tangible personal property Collateral and carry such other business insurance, with insurers reasonably acceptable to Bank, in such form and amounts as Bank may reasonably require and that are customary and in
accordance with standard practices for Borrower’s industry and locations, and Borrower shall provide evidence of such insurance to Bank. All casualty insurance policies shall name Bank as loss payee and shall contain a lenders loss payee
endorsement in form reasonably acceptable to Bank. All policies of liability insurance shall name Bank as an additional insured. Upon receipt of the proceeds of any such insurance, Bank shall apply such proceeds in reduction of the Obligations as
Bank shall determine in its good faith business judgment, except that, provided no Default or Event of Default has occurred and is continuing, Bank shall release to Borrower casualty insurance proceeds totaling less than $250,000, which shall be
utilized by Borrower for the replacement of the property with respect to which the insurance proceeds were paid. Bank may require reasonable assurance that the insurance proceeds so released will be so used. If Borrower fails to provide or pay for
any insurance, Bank may, but is not obligated to, obtain the same at Borrower’s expense. Borrower shall promptly deliver to Bank copies of all material reports made to insurance companies. 
  
 5.3 Reports. Borrower, at its expense, shall
provide Bank with the written reports set forth in the Schedule, and such other written reports with respect to Borrower (including budgets, sales projections, operating plans and other financial documentation), as Bank shall from time to time
reasonably specify in its good faith business judgment. 
  
 5.4 Access to Collateral, Books and Records. At reasonable times, and on one Business Day’s notice, Bank, or its agents, shall have the right to inspect the Collateral and the right to audit and copy
Borrower’s books and records. After the initial inspection and audit, such inspections and audits shall occur quarterly or more frequently at Bank’s discretion. Bank shall take reasonable steps to keep confidential all information obtained
in any such inspection or audit, but Bank shall have the right to disclose any such information to its auditors, regulatory agencies, and attorneys, and pursuant to any subpoena or other legal process. 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; provided that so long as no
Event of Default has occurred and is continuing, Borrower shall not be required to pay such expenses more than once per fiscal quarter. In the event Borrower and Bank schedule an audit more than ten days in advance, and Borrower seeks to reschedule
the audit with less than ten days written notice to Bank, then (without limiting any of Bank’s rights or remedies), Borrower shall pay Bank a cancellation 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. 
  

 -9- 

 5.5 Negative Covenants. Except as may be permitted in the Schedule, Borrower
shall not, and shall not permit any Subsidiary to, without Bank’s prior written consent (which shall be a matter of its good faith business judgment), do any of the following: 
  
 (a) merge or consolidate with another corporation or entity (except that a Subsidiary may merge or
consolidate with or into another Subsidiary or Borrower); or acquire all or substantially all of the capital stock or property of a Person other than a Subsidiary; provided that Borrower or a Subsidiary may merge or consolidate with another
corporation or entity or acquire all or substantially all of the capital stock or property of a Person other than a Subsidiary, if (i) a Default or Event of Default shall not have occurred and be continuing and would not occur as a result of such
transaction; and (ii) such transaction shall not result in a decrease in excess of 25% of Tangible Net Worth of Borrower on a consolidated basis after giving effect to the transaction; 
  
 (b) enter into any material transaction with any Affiliate of Borrower except for (i) transactions that are
in the ordinary course of Borrower’s business, upon fair and reasonable terms (when viewed in the context of any series of transactions of which it may be a part, if applicable); and (ii) transactions permitted under Sections 5.5(f) or (i);

  
 (c) Convey, sell, lease, transfer or
otherwise dispose of (collectively “Transfer”) all or any part of its business or property, except for: 
  
 (i) sales of Inventory in the ordinary course of business; 
  
 (ii) Transfers associated with the making or disposition of a Permitted Investment; 
  
 (iii) Dispositions of cash or Permitted Investments in a
manner not prohibited by this Agreement; 
  
 (iv)
Dispositions of obsolete, damaged or worn-out equipment in the ordinary course of business; 
  
 (v) Licensing of intellectual property in the ordinary course of business; and 
  
 (vi) Transfers not otherwise permitted in this Section
5.5(c), provided, that the aggregate book value of all such other Transfers by Borrower and its Subsidiaries, together, shall not exceed in any fiscal year, $1,000,000; 
  
 (d) without prior written notice to Bank, store any Inventory or other Collateral with any warehouseman or
other third party not specified in the Representations or otherwise consented to in writing by Bank; 
  
 (e) sell any Inventory on a sale-or-return, guaranteed sale, consignment, or other contingent basis; 
  
 (f) make any loans of any money or other assets except for
Permitted Investments; 
  
 (g) incur any
Indebtedness, other than Permitted Indebtedness; 
  

 -10- 

 (h) guarantee or otherwise become liable with respect to the obligations of another party
or entity other than Permitted Indebtedness; 
  
 (i) pay or declare any dividends on stock or redeem, retire, purchase or otherwise acquire, directly or indirectly, any of Borrower’s stock except for Permitted Distributions; 
  
 (j) permit, vote in favor of, or enter into any agreement
that would result in, a Change of Control; 
  
 (k) engage, directly or indirectly, in any material line of business other than those lines of business conducted by Borrower and its Subsidiaries on the date hereof and any businesses reasonably related, complementary or incidental thereto
or reasonable extensions thereof; or 
  
 (l) with
respect to Borrower only, dissolve or elect to dissolve, or, without prior written notice to Bank, change its state of incorporation. 
  
 Transactions not otherwise prohibited by this Section 5.5 are only permitted if no Default or Event of Default would occur as a result of such
transaction.

 6.3 Payment of Obligations. On the Maturity Date or on any earlier effective
date of termination, Borrower shall pay and perform in full all Obligations, whether evidenced by installment notes or otherwise, and whether or not all or any part of such Obligations are otherwise then due and payable. Without limiting the
generality of the foregoing, if on the Maturity Date, or on any earlier effective date of termination, there are any outstanding Letters of Credit issued by Bank or issued by another institution based upon an application, guarantee, indemnity or
similar agreement on the part of Bank, 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, pursuant to Bank’s then standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Bank’s security interests in all of the Collateral and all of the terms and provisions of this Agreement shall continue in full force and effect until all Obligations have been paid and performed in full; provided that Bank
may, in its sole discretion, refuse to make any further Advances after termination. No termination shall in any way affect or impair any right or remedy of Bank, nor shall any such termination relieve Borrower of any Obligation to Bank, until all of
the Obligations have been paid and performed in full. Upon payment and performance in full of all the Obligations and termination of this Agreement, Bank shall promptly terminate its financing statements with respect to the Borrower and deliver to
Borrower such other documents as may be required to fully terminate Bank’s security interests.

announcement at the time scheduled for sale. Bank shall have the right to conduct such disposition on Borrower’s premises without charge, for such time or times as Bank deems reasonable, or on Bank’s premises, or elsewhere and the
Collateral need not be located at the place of disposition. Bank may directly or through any affiliated company purchase or lease any Collateral at any such public disposition, and if permissible under applicable law, at any private disposition. Any

and after the occurrence and during the continuance of any Event of Default, the interest rate applicable to the Obligations shall be increased by an additional four percent per annum (the “Default Rate”). 
  
 7.3 Standards for Determining Commercial
Reasonableness. Borrower and Bank agree that a sale or other disposition (collectively, “Sale”) of any Collateral which complies with the following standards will conclusively be deemed to be commercially reasonable: (a)
notice of the sale is given to Borrower at least ten days prior to the sale, and, in the case of a public sale, notice of the sale is published at least five days before the sale in a newspaper of general circulation in the county where the sale is
to be conducted; (b) notice of the sale describes the collateral in general, non-specific terms; (c) the sale is conducted at a place designated by Bank, with or without the Collateral being present; (d) the sale commences at any time between 8:00
a.m. and 6:00 p.m; (e) payment of the purchase price in cash or by cashier’s check or wire transfer is required; and (f) with respect to any sale of any of the Collateral, Bank may (but is not obligated to) direct any prospective purchaser to

 -14- 

 
information concerning the same. Bank shall be free to employ other methods of noticing and selling the Collateral, in its discretion, if they are
commercially reasonable. 
  
 7.4 Power of
Attorney. Upon the occurrence and during the continuance of any Event of Default, without limiting Bank’s other rights and remedies, Borrower grants to Bank an irrevocable power of attorney coupled with an interest, authorizing and
permitting Bank (acting through any of its employees, attorneys or agents) at any time, at its option, but without obligation, with or without notice to Borrower, and at Borrower’s expense, to do any or all of the following, in Borrower’s
name or otherwise, but Bank agrees that if it exercises any right hereunder, it will do so in good faith and in a commercially reasonable manner: (a) Execute on behalf of Borrower any documents that Bank may, in its good faith business judgment,
deem advisable in order to perfect and maintain Bank’s security interest in the Collateral, or in order to exercise a right of Borrower or Bank, or in order to fully consummate all the transactions contemplated under this Agreement, and all
other Loan Documents; (b) Execute on behalf of Borrower, any invoices relating to any Account, any draft against any Account Debtor and any notice to any Account Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim of mechanic’s,
materialman’s or other lien, or assignment or satisfaction of mechanic’s, materialman’s or other lien; (c) Take control in any manner of any cash or non-cash items of payment or proceeds of Collateral; endorse the name of Borrower
upon any instruments, or documents, evidence of payment or Collateral that may come into Bank’s possession; (d) Endorse all checks and other forms of remittances received by Bank; (e) Pay, contest or settle any lien, charge, encumbrance,

and any and all reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Bank with respect to the foregoing shall be added to and become part of the Obligations, shall be payable on demand, and shall bear interest at
a rate equal to the highest interest rate applicable to any of the Obligations. In no event shall Bank’s rights under the foregoing power of attorney or any of Bank’s other rights under this Agreement be deemed to indicate that Bank is in
control of the business, management or properties of Borrower. 
  
 7.5 Application of Proceeds. All proceeds realized as the result of any sale of the Collateral shall be applied by Bank, first, to the costs, expenses, liabilities, obligations and attorneys’ fees incurred
by Bank in the exercise of its rights under this Agreement, second, to the interest due upon any of the Obligations, and third, to the principal of the Obligations, in such order as Bank shall determine in its sole discretion. Any surplus shall be
paid to Borrower or 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 

  

 -15- 

 
option, exercisable at any time, in its good faith business judgment, of either reducing the Obligations by the principal amount of purchase price or
deferring the reduction of the Obligations until the actual receipt by Bank of the cash therefor. 
  
 7.6 Remedies Cumulative. In addition to the rights and remedies set forth in this Agreement, Bank shall have all the other
rights and remedies accorded a secured party under the Code and under all other applicable laws, and under any other instrument or agreement now or in the future entered into between Bank and Borrower, and all of such rights and remedies are
cumulative and none is exclusive. Exercise or partial exercise by Bank of one or more of its rights or remedies shall not be deemed an election, nor bar Bank from subsequent exercise or partial exercise of any other rights or remedies. The failure
or delay of Bank to exercise any rights or remedies shall not operate as a waiver thereof, but all rights and remedies shall continue in full force and effect until all of the Obligations have been fully paid and performed.

 9.1 EXIM Agreement; Cross-Collateralization; Cross-Default; Conflicts. Both this Agreement and the EXIM Agreement shall
continue in full force and effect, and all rights and 

  

 -27- 

 
remedies under this Agreement and the EXIM Agreement are cumulative. The term “Obligations” as used in this Agreement and in the EXIM
Agreement shall include without limitation the obligation to pay when due all loans made pursuant to the EXIM Agreement (the “EXIM Loans”) and all interest thereon and the obligation to pay when due all Advances made pursuant to the
terms of this Agreement and all interest thereon. Without limiting the generality of the foregoing, all “Collateral” as defined in this Agreement and as defined in the EXIM Agreement shall secure all EXIM Loans and all Advances and
all interest thereon, and all other Obligations. Any Event of Default under this Agreement shall also constitute an Event of Default under the EXIM Agreement, and any Event of Default under the EXIM 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 EXIM Agreement and/or under any note evidencing Advances, 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 the EXIM Agreement and/or note
assigned and to specify the priorities of the respective security interests in such Collateral between itself and the assignee, all without notice to or consent of the Borrower. Should any term of this Agreement conflict with any term of the EXIM
Agreement, the more restrictive term in either agreement shall govern the Borrower. 
  
 9.2 Interest Computation; Float Charge. In computing interest on the Obligations, all Payments received after 12:00 Noon Pacific time on any day shall be deemed received on the next
Business Day. In addition, whenever Advances are outstanding, Bank shall be entitled to charge Borrower a “float” charge in an amount equal to three Business Days interest, at the interest rate applicable to the Loans, on all Payments
received by Bank. The float charge for each month shall be payable on the last day of the 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 loan account for the amount of any item of payment which is returned to Bank unpaid. 
  
 9.3 Application of Payments. All payments with respect to the Obligations may be applied, and in Bank’s good faith
business judgment reversed and re-applied, to the Obligations, in such order and manner as Bank shall determine in its good faith business judgment. 
  
 9.4 Charges to Accounts. Bank may, in its discretion, require that Borrower pay monetary Obligations in cash to Bank or charge
any monetary Obligations to Borrower’s deposit accounts maintained with Bank, or, if no amounts are available in such deposit accounts, charge them to Borrower’s loan account with Bank, in which event they will bear interest at the same
rate applicable to the Advances. 
  
 9.5
Monthly Accountings. Bank shall provide Borrower monthly with an account of advances, charges, expenses and payments made pursuant to this Agreement. Such account shall be deemed correct, accurate and binding on Borrower and an
account stated (except for reverses and reapplications of payments made and corrections of errors discovered by Bank), unless Borrower notifies Bank in writing to the contrary within 60 days after such account is rendered, describing the nature of
any alleged errors or omissions.

and shall be given either personally or by reputable private delivery service or by regular first-class mail, or certified mail return receipt requested, addressed to Bank or Borrower at the addresses shown in the heading to this Agreement, or at
any other address designated in writing by one party to the other party. Notices to Bank shall be directed to the Commercial Finance Division, to the attention of the Division Manager or the Division Credit Manager. All notices shall be deemed to

with postage prepaid. 
  
 9.7
Severability. Should any provision of this Agreement be held by any court of competent jurisdiction to be void or unenforceable, such defect shall not affect the remainder of this Agreement, which shall continue in full force
and effect. 
  
 9.8 Integration. This
Agreement and such other written agreements, documents and instruments as may be executed in connection herewith are the final, entire and complete agreement between Borrower and Bank and supersede all prior and contemporaneous negotiations and oral
representations and agreements, all of which are merged and integrated in this Agreement. There are no oral understandings, representations or agreements between the parties which are not set forth in this Agreement or in other written agreements
signed by the parties in connection herewith. 
  
 9.9
Waivers; Indemnity. The failure of Bank at any time or times to require Borrower to strictly comply with any of the provisions of this Agreement or any other Loan Document shall not waive or diminish any right of Bank later to
demand and receive strict compliance therewith. Any waiver of any default shall not waive or affect any other default, whether prior or subsequent, and whether or not similar. None of the provisions of this Agreement or any other Loan Document shall
be deemed to have been waived by any act or knowledge of Bank or its agents or employees, but only by a specific written waiver signed by an authorized officer of Bank and delivered to Borrower. Borrower waives the benefit of all statutes of
limitations relating to any of the Obligations or this Agreement or any other Loan Document, and Borrower waives demand, protest, notice of protest and notice of default or dishonor, notice of payment and nonpayment, release, compromise, settlement,
extension or renewal of any commercial paper, instrument, account, General Intangible, document or guaranty at any time held by Bank on which Borrower is or may in any way be liable, and notice of any action taken by Bank, unless expressly required
by this Agreement. Borrower hereby agrees to indemnify Bank and its affiliates, subsidiaries, parent, directors, officers, employees, agents, and attorneys, and to hold them harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, costs and expenses (including reasonable attorneys’ fees), of every kind, which they may sustain or incur based upon or arising out of any of the Obligations, or any relationship or agreement
between Bank and Borrower, or any other matter, relating to Borrower or the Obligations; provided that this indemnity shall not extend to damages proximately caused by the indemnitee’s own gross negligence or willful misconduct. Notwithstanding
any provision in this Agreement to the contrary, the indemnity agreement set forth in this Section shall survive any termination of this Agreement and shall for all purposes continue in full force and effect. 
  

 -29- 

 9.10 No Liability for Ordinary Negligence. Neither Bank, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Bank shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower or any
other party through the ordinary negligence of Bank, or any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Bank, but nothing herein shall relieve Bank from liability for its own gross
negligence or willful misconduct. 
  
 9.11
Amendment. The terms and provisions of this Agreement may not be waived or amended, except in a writing executed by Borrower and a duly authorized officer of Bank. 
  
 9.12 Time of Essence. Time is of the essence in the performance by Borrower of each and every
obligation under this Agreement. 
  
 9.13
Attorneys’ Fees and Costs. Borrower shall reimburse Bank for all reasonable attorneys’ fees and all filing, recording, search, title insurance, appraisal, audit, and other reasonable costs incurred by Bank, pursuant
to, or in connection with, or relating to this Agreement (whether or not a lawsuit is filed), including, but not limited to, any reasonable attorneys’ fees and costs Bank incurs in order to do the following: prepare and negotiate this Agreement
and all present and future documents relating to this Agreement; obtain legal advice in connection with this Agreement or Borrower; enforce, or seek to enforce, any of its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any complaint to be relieved of the automatic stay in bankruptcy; file or prosecute any probate claim, bankruptcy claim, third-party claim, or other claim; subject to any
limitations on fees specified elsewhere herein, examine, audit, copy, and inspect any of the Collateral or any of Borrower’s books and records; protect, obtain possession of, lease, dispose of, or otherwise enforce Bank’s security interest
in, the Collateral; and otherwise represent Bank in any litigation relating to Borrower. In satisfying Borrower’s obligation hereunder to reimburse Bank for attorneys fees, Borrower may, for convenience, issue checks directly to Bank’s
attorneys, Bingham McCutchen LLP, but Borrower acknowledges and agrees that Bingham McCutchen LLP is representing only Bank and not Borrower in connection with this Agreement. If either Bank or Borrower files any lawsuit against the other predicated
on a breach of this Agreement, the prevailing party in such action shall be entitled to recover its reasonable costs and attorneys’ fees, including (but not limited to) reasonable attorneys’ fees and costs incurred in the enforcement of,
execution upon or defense of any order, decree, award or judgment. All attorneys’ fees and costs to which Bank may be entitled pursuant to this Section shall immediately become part of the Obligations, shall be due on demand and shall bear
interest at a rate equal to the highest interest rate applicable to any of the Obligations. 
  
 9.14 Benefit of Agreement. The provisions of this Agreement shall be binding upon and inure to the benefit of the respective successors, assigns, heirs, beneficiaries and representatives of
Borrower and Bank; provided, however, that Borrower may not assign or transfer any of its rights under this Agreement without the prior written consent of Bank, and any prohibited assignment shall be void. No consent by Bank to any assignment shall
release Borrower from its liability for the Obligations. 
  

 -30- 

 9.15 Limitation of Actions. Any claim or cause of action by Borrower against
Bank, its directors, officers, employees, agents, accountants or attorneys, based upon, arising from, or relating to this Agreement, or any other Loan Document, or any other transaction contemplated hereby or thereby or relating hereto or thereto,
or any other matter, cause or thing whatsoever, occurred, done, omitted or suffered to be done by Bank, its directors, officers, employees, agents, accountants or attorneys, shall be barred unless asserted by Borrower by the commencement of an
action or proceeding in a court of competent jurisdiction by the filing of a complaint within one year after the first act, occurrence or omission upon which such claim or cause of action, or any part thereof, is based, and the service of a summons
and complaint on an officer of Bank, or on any other person authorized to accept service on behalf of Bank, within thirty (30) days thereafter. Borrower agrees that such one-year period is a reasonable and sufficient time for Borrower to investigate
and act upon any such claim or cause of action. The one-year period provided herein shall not be waived, tolled, or extended except by the written consent of Bank in its sole discretion. This provision shall survive any termination of this Agreement
or any other Loan Document. 
  
 9.16 Paragraph
Headings; Construction. Paragraph headings are only used in this Agreement for convenience. Borrower and Bank acknowledge that the headings may not describe completely the subject matter of the applicable paragraph, and the headings shall
not be used in any manner to construe, limit, define or interpret any term or provision of this Agreement. This Agreement has been fully reviewed and negotiated between the parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Bank or Borrower under any rule of construction or otherwise. 
  
 9.17 Governing Law; Jurisdiction; Venue. This Agreement and all acts and transactions hereunder and all rights and obligations
of Bank and Borrower shall be governed by the laws of the State of California. As a material part of the consideration to Bank to enter into this Agreement, Borrower (a) agrees that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Bank’s option, be litigated in courts located within California, and that the exclusive venue therefor shall be Santa Clara County; (b) consents to the jurisdiction and venue of any such court and consents to service of
process in any such action or proceeding by personal delivery or any other method permitted by law; and (c) waives any and all rights Borrower may have to object to the jurisdiction of any such court, or to transfer or change the venue of any such
action or proceeding. 
  
 9.18
Mutual Waiver of Jury Trial. BORROWER AND BANK EACH HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR
FUTURE INSTRUMENT OR AGREEMENT BETWEEN BANK AND BORROWER, OR ANY CONDUCT, ACTS OR OMISSIONS OF BANK OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH BANK OR BORROWER, IN ALL OF THE
FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE. 
  
 9.19 Confidentiality. In handling any confidential information of Borrower, Bank will exercise the same degree of care that it exercises for its own proprietary information, but 

  

 -31- 

 
disclosure of information may be made: (a) to Bank’s subsidiaries or affiliates in connection with their present or prospective business relations with
Borrower; (b) to prospective transferees or purchasers of any interest in the Loans which agree to maintain the confidentiality of such information pursuant to an agreement substantially similar to this Section 9.19; (c) as required by law,
regulation, subpoena, or other order so long as Borrower is given notice thereof if practicable (and Bank is permitted to provide such notice) and an opportunity to seek a protective order, (d) as required in connection with Bank’s examination
or audit; and (e) as Bank considers appropriate in exercising remedies under this Agreement. Confidential information does not include information that either: (x) is in the public domain or in Bank’s possession when disclosed to Bank, or

 This Schedule forms an integral part
of the Loan and Security Agreement between Silicon Valley Bank and Borrower of even date. 
  

			
	 1.      CREDIT LIMIT
	  	 
	 (Section 1.1):
	  	An amount (the “Credit Limit”) not to exceed the lesser of: (a) $20,000,000 at any one time outstanding (the “Maximum Credit Limit”); or (b) the sum of (i)
amounts available under the Domestic Borrowing Base plus (ii) amounts available under the EXIM Borrowing Base.
		
	 	  	Bank may, from time to time, modify the Domestic Borrowing Base or the EXIM Borrowing Base, in its good faith business judgment, upon notice to the Borrower, based on changes in collection
experience with respect to Eligible Domestic Accounts and Eligible Foreign Accounts or other issues or factors relating to the Eligible Domestic Accounts and Eligible Foreign Accounts or other Collateral.
		
	 	  	Notwithstanding anything to the contrary herein, except as otherwise provided in Section 1.5, the aggregate amount of all outstanding Advances and amounts outstanding under the sublimits set
forth below, shall not exceed the Maximum Credit Limit.
		
	 Sublimits
	  	 
	 (Sections 1.5 and 1.8):
	  	 
		
	 Cash Management
	  	 
	 Services and Reserves:
	  	So long as Borrower maintains at all times with Bank unrestricted cash balances (net of Advances) of at least $7,000,000, Borrower may use amounts not to exceed $16,000,000 minus the
sum of (a) the face amount of all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) and (b) the FX Reserve, for Bank’s Cash Management Services (as defined below), including, merchant services, business credit
card, ACH and other services identified in the cash management services agreement related to such service (the “Cash Management Services”). Bank may, in its sole discretion, reserve against Advances which would otherwise be
available

	Silicon Valley Bank	 	Schedule to loan and Security Agreement

  

			
	 	  	hereunder such sums as Bank shall determine in its good faith business judgment in connection with the Cash Management Services, and Bank may charge to Borrower’s loan account or deposit
accounts with Bank, any amounts that may become due or owing to Bank in connection with the Cash Management Services. Borrower agrees to execute and deliver to Bank all standard form applications and agreements of Bank in connection with the Cash
Management Services, and, without limiting any of the terms of such applications and agreements, Borrower will pay all standard fees and charges of Bank in connection with the Cash Management Services. The Cash Management Services shall terminate on
the Maturity Date.
		
	 Foreign Exchange
	  	 
	 Contract Sublimit:
	  	So long as Borrower maintains at all times with Bank unrestricted cash balances (net of Advances) of at least $7,000,000, Borrower may enter into foreign exchange forward contracts with Bank,
on its standard forms, under which Borrower commits to purchase from or sell to Bank a set amount of foreign currency more than one business day after the contract date (the “FX Forward Contracts”). Bank will subtract ten percent of
each outstanding FX Forward Contract from the foreign exchange sublimit which is a maximum of $16,000,000 minus the sum of (a) all amounts utilized for Cash Management Services and (b) the amount of outstanding Letters of Credit (including
drawn but unreimbursed Letters of Credit) (the “FX Reserve”). The aggregate amount of the FX Forward Contracts at any one time may not exceed ten times the amount of the FX Reserve (which shall be in addition to other reserves). In
the event at any time there are insufficient amounts available to Borrower for such FX Reserve, Borrower shall deposit and maintain with Bank cash collateral in an amount at all times equal to such deficiency, which shall be held as Collateral for
all purposes of this Agreement. Bank may, in its discretion, terminate the FX Forward Contracts at any time that an Event of Default occurs and is continuing or when Borrower fails to maintain with Bank the unrestricted cash balance set forth in the
first sentence hereof. Borrower shall execute all standard form applications and agreements of Bank in connection with the FX Forward Contracts, and without limiting any of the terms of such applications and agreements, Borrower shall pay all
standard fees and charges of Bank in connection with the FX Forward Contracts.
		
	 Letter of Credit Sublimit:
	  	So long as (a) Borrower maintains at all times with Bank unrestricted cash balances (net of Advances) of at least $7,000,000, and (b) Borrower’s minimum Tangible Net Worth is not less
than that required under the First Reset Conditions, Bank will issue or have issued Letters of Credit for Borrower’s account not exceeding $16,000,000 minus the sum of (a) the FX Reserve, and (b) amounts used for Cash Management
Services. Each Letter of Credit will have

	 	  	an expiry date of no later than thirty days prior to the Maturity Date, and Borrower’s reimbursement obligation will be fully secured by cash pursuant to the terms of Section 1.6 of the
Agreement.
		
	 Overadvance Sublimit:
	  	Subject to Bank’s sole discretion, Borrower may borrow an Advance or Advances of up to an aggregate amount not to exceed $3,000,000 over the Credit Limit (collectively, the
“Permitted Overadvances”), so long as (a) Borrower maintains at all times with Bank unrestricted cash balances (net of Advances) of at least $9,000,000, and (b) neither the First Reset Conditions nor the Second Reset conditions
apply. Borrower shall repay the outstanding amount of any Overadvance within 45 days after such Overadvance is made. If any Overadvances exceed $3,000,000, Borrower shall immediately pay Bank the excess.
		
	 2.      INTEREST.
	  	 
		
	 Interest Rate
	  	 
	 (SECTION 1.4):
	  	A rate equal to the “Prime Rate” in effect from time to time, plus 2% per annum, provided that the interest rate in effect on any day shall not be less than 6% per annum. Interest
shall be calculated on the basis of a 360-day year for the actual number of days elapsed. “Prime Rate” means the rate announced from time to time by Bank as its “prime rate;” it is a base rate upon which other rates charged by
Bank are based, and it is not necessarily the best rate available at Bank. The interest rate applicable to the Obligations shall change on each date there is a change in the Prime Rate.
		
	 	  	Second Reset Conditions - A rate equal to the “Prime Rate” in effect from time to time, plus 4% per annum, provided that the interest rate in effect on any day shall
not be less than 8% per annum. Interest shall be calculated on the basis of a 360-day year for the actual number of days elapsed. “Prime Rate” means the rate announced from time to time by Bank as its “prime rate;” it is a base
rate upon which other rates charged by Bank are based, and it is not necessarily the best rate available at Bank. The interest rate applicable to the Obligations shall change on each date there is a change in the Prime Rate.

	 	Re:	Redback Networks, Inc . (the “Borrower”) 

  
 Ladies and Gentlemen: 
  
 Pursuant to the terms of a Loan and Security Agreement between us and the Borrower dated March 10, 2004 (the “Loan Agreement”), we act as the
lender for the Borrower and have been granted a security interest in all of its inventory and other personal property assets (collectively, the “Collateral”). We understand that from time to time Collateral is delivered to you for storage,
processing and/or other purposes. 
  
 This letter constitutes

 -1-Employment  Agreement

 EXHIBIT 10.7 
  
 EMPLOYMENT AGREEMENT 
  
 THIS EMPLOYMENT AGREEMENT (the “Agreement”) is entered into by and between Radian Group Inc. (the “Company”) and Frank P. Filipps (the
“Executive”) and shall be effective as of November 11, 2003 (the “Effective Date”). 
  
 WHEREAS, the Company desires to continue to employ the Executive as its Chief Executive Officer and the Executive desires to continue to serve in such
capacity on behalf of the Company. 
  
 NOW, THEREFORE, in
consideration of the premises and of the mutual covenants and agreements hereinafter set forth, the Company and the Executive hereby agree as follows: 
  
 1. Employment. 
  
 (a) Term. The term of this Agreement (the “Term”) shall begin as of the Effective Date and shall terminate on November
10, 2004, unless sooner terminated by either party as hereinafter provided. In no event shall the expiration of this Agreement be deemed, in and of itself, a termination of the Executive’s employment for purposes of this Agreement, including a
termination without Cause for purposes of Section 9. 
  
 (b) Duties. The Executive shall serve as the Chief Executive Officer of the Company and shall report to the Board of Directors of the Company (the “Board”) and the Lead Director of the Board. The Executive shall perform all
duties and accept all responsibilities incident to such position as may be reasonably assigned to him by the Board. 
  
 (c) Best Efforts. During the Term, the Executive shall devote his best efforts and full time and attention to promote the business
and affairs of the Company and its affiliated companies, and shall be engaged in other business activities only to the extent that such activities do not interfere or conflict with his obligations to the Company hereunder, including, without
limitation, obligations pursuant to Section 15 below. The foregoing also shall not be construed as preventing the Executive from (1) serving on civic, educational, philanthropic or charitable boards or committees, or, with the consent of the Board,
in its sole discretion, on corporate boards (2) delivering lectures, fulfilling speaking engagements or lecturing at educational institutions and (3) managing personal investments, so long as such activities do not significantly interfere with the
performance of the Executive’s responsibilities hereunder; provided, however, that the Executive shall not invest in any business competitive with the Company, except that the Executive shall be permitted to own passively not more than 5% of
the stock of those companies whose securities are listed on a national securities exchange or on the NASDAQ system. Notwithstanding the foregoing, the Executive may request permission from the Board to acquire passive ownership of more than 5% of
the stock of a company whose securities are listed on a national securities exchange or on the NASDAQ system, which such permission shall not be unreasonably withheld. 
  
 2. Base Salary and Bonus. As compensation for the services to be rendered hereunder, the Company shall pay to the
Executive an annual base salary at the level in effect as of the Effective Date. This amount may be subject to annual adjustment at beginning of each Company fiscal year, as determined by the Board, in its sole discretion. The Executive’s base

  

 
salary shall be paid in accordance with the Company’s existing payroll policies, and shall be subject to applicable withholding taxes. For the
Company’s 2003 fiscal year, the Executive shall be eligible for an annual bonus to be determined in the sole discretion of the Compensation and Human Resources Committee of the Board (the “Compensation Committee”). Beginning with the
Company’s 2004 fiscal year, the Executive shall also be eligible for annual bonus payments if certain individual and corporate performance goals and targets, established by the Compensation Committee, in its sole discretion, are met. The
performance goals and targets shall be determined by the Compensation Committee, in its sole discretion, at the beginning of each such fiscal year. At the end of each fiscal year, the Compensation Committee shall review actual performance against
the applicable performance goals and targets and shall notify the Executive of the amount of his bonus award, if any. The Executive’s bonus shall be paid to him after the end of the fiscal year to which it relates, at the same time and under
the same terms and conditions as other executives of the Company. 
  
 3. Equity Compensation. The Executive shall be entitled to participate in any short-term and long-term equity incentive programs established by the Company for its senior level executives generally, including the Company’s
Equity Compensation Plan, at levels determined by the Compensation Committee, in its sole discretion. 
  
 4. Retirement and Welfare Benefits. The Executive shall be entitled to participate in the Company’s health, life insurance, long and
short-term disability, dental, retirement, and medical programs, if any, pursuant to their respective terms and conditions. Nothing in this Agreement shall preclude the Company or any affiliate of the Company from terminating or amending any
employee benefit plan or program from time to time after the effective date of this Agreement. 
  
 5. Vacation. The Executive shall be entitled to vacation, holiday and sick leave at levels commensurate with those provided to other senior executive officers of the Company, in accordance with the
Company’s vacation, holiday and other pay for time not worked policies. 
  
 6. Expenses. The Company shall reimburse the Executive for all necessary and reasonable travel and other business expenses incurred by the Executive in the performance of his duties hereunder in accordance with
such reasonable accounting procedures as the Company may adopt generally from time to time for executives. In addition, the Company agrees to pay all legal fees reasonably incurred by the Executive in connection with the negotiation of this
Agreement. 
  
 7. Perquisites. The Executive shall be
provided with such other executive perquisites as may be provided to other senior executive officers of the Company. 
  
 8. Indemnification. The Company agrees to indemnify the Executive against all claims arising out of actions or omissions during the
Executive’s employment by the Company, to the same extent and on the same terms and conditions provided for in the Company’s bylaws or under the Delaware General Corporation Law, each as in effect on the Effective Date. The Company agrees
it will continue to maintain officers’ and directors’ liability insurance to fund the indemnity described above in the same amount and to the same extent it maintains such coverage for the benefit of its other officers and directors.

  

 2 

 9. Termination Without Cause. 
  
 (a) The Company may terminate the Executive’s employment with the Company at any time without Cause (as
defined in Section 13) from the position in which the Executive is employed hereunder upon not less than 15 days’ prior written notice to the Executive; provided, however, that in the event that such notice is given, the Executive shall be
under no obligation to render any additional services to the Company and shall be allowed to seek other employment. On the date of termination specified in such notice, the Executive agrees to resign all positions, including as an officer, and Board
memberships related to the Company and its subsidiaries and affiliates. 
  
 (b) Upon any termination described in Section 9(a) above, the Executive shall be entitled to receive only the amount due to the Executive under the Company’s then current severance pay plan for employees, if any,
but only to the extent not conditioned on the execution of a release by the Executive. No other payments or benefits shall be due under this Agreement to the Executive, but the Executive shall be entitled to any benefits accrued and due in
accordance with the terms of any applicable benefit plans and programs of the Company. 
  
 (c) Notwithstanding the provisions of Section 9(b), if the Executive executes and does not revoke a written release upon any termination
described in Section 9(a) above, in a form acceptable to the Company, but substantially in the form attached hereto as Exhibit A (but subject to any necessary adjustment reasonably determined by the Company to be necessary to comply with
applicable law at the time of the Executive’s termination) (the “Release”), of any and all claims against the Company and all related parties with respect to all matters arising out of the Executive’s employment by the Company,
or the termination thereof (other than claims for any entitlements under the terms of this Agreement or under any plans or programs of the Company under which the Executive has accrued and is due a benefit or any claims the Executive may have as a
stockholder of the Company; provided that the Executive is not the moving, initiating or lead party), and any claims against the Executive for actions within the scope of his employment by the Company, the Executive shall be entitled to receive, in
lieu of the payment described in Section 9(b) and any other payments due under any severance plan or program for employees or executives, the following: 
  
 (1) If the Executive’s employment is terminated during the Term, the Company shall pay to the Executive severance equal to the
product of (A) and (B) where (A) is a fraction, the numerator of which is the 365 plus the number of days remaining in the Term as of the Executive’s termination date and the denominator of which is 366 and (B) is the sum of the
Executive’s annual base salary (at the rate in effect at the time of the Executive’s termination) plus an amount equal to the average annual bonus payable (without regard to whether any deferral is elected by the Executive) to the
Executive for the three years preceding the date of the Executive’s termination of employment. The severance amount shall be paid in equal monthly installments over a period equal to 12 months plus the number of whole months remaining in the
Term as of the date of the Executive’s termination. The period during which the monthly installments described in the preceding sentence shall be called the “Severance Period.” 
  
 Payment of severance described above shall commence
immediately after the end of the revocation period for the Release. 
  

 3 

 (2) Medical coverage for the Severance Period under Section 9(c)(l) above following the
date of termination or until the date on which the Executive is eligible for coverage under a plan maintained by a new employer or under a plan maintained by his spouse’s employer, at the level in effect at the date of his termination (or
generally comparable coverage) for himself and, where applicable, his spouse and dependents, as the same may be changed by the Company from time to time for employees generally, as if the Executive had continued in employment during such period; or,
alternatively, the Company may pay to the Executive cash in lieu of such coverage in an amount equal to the Executive’s after-tax cost of continuing such coverage, where such coverage may not be continued (or where such continuation would
adversely affect the tax status of the plan pursuant to which the coverage is provided). The COBRA health care continuation coverage period under section 4980B of the Internal Revenue Code of 1986, as amended, shall run concurrently with the
foregoing benefit period. 
  
 (3) Any other
amounts earned, accrued and owing but not yet paid under Section 2 above. 
  
 (d) Notwithstanding any provision of this Agreement to the contrary, in the event the Executive’s employment is terminated without Cause, any such termination shall be treated as an election to retire, and actual
retirement by the Executive, such that the Executive shall be fully vested in (1) all outstanding equity awards held by the Executive at the date of his termination of employment and (2) the benefit payable under the terms of the Company’s
Supplemental Executive Retirement Plan (the “SERP”), regardless of whether the Executive signs and does not revoke the Release; provided that all outstanding equity awards held by the Executive at the date of his termination of employment
shall remain subject to the terms of the applicable agreements and/or the plans pursuant to which they were granted and the benefit to which the Executive is entitled under the SERP shall be payable in accordance with the terms of the plan document,
as in effect on the Executive’s termination date. 
  
 10.
Voluntary Termination. The Executive may voluntarily terminate his employment for any reason upon 15 days’ prior written notice. In such event, after the effective date of such termination, no payments shall be due under this Agreement,
except that the Executive shall be entitled to any benefits accrued and due in accordance with the terms of any applicable benefit plans and programs of the Company. 
  
 11. Disability. If the Executive incurs a Disability (as defined below) during the Term, the Executive’s
employment shall terminate on the date of Disability. If the Executive’s employment terminates on account of his Disability, the Executive shall be entitled to receive any benefits accrued and due in accordance with the terms of any applicable
benefit plans and programs of the Company. For purposes of this Agreement, the term “Disability” shall have the same meaning as under the Company’s long-term disability plan. 
  
 12. Death. If the Executive dies while employed by the Company, the
Executive’s employment shall terminate on the date of death and the Company shall pay to the Executive’s executor, legal representative, administrator or designated beneficiary, as applicable, any amounts earned, accrued and owing but not
yet paid under Section 2 above and any benefits accrued and due under the Company’s benefit plans and programs. Otherwise, the Company shall have no further liability or obligation under this Agreement to the Executive’s executors, 

  

 4 

 
legal representatives, administrators, heirs or assigns or any other person claiming under or through the Executive. 
  
 13. Cause. The Company may terminate the Executive’s employment
at any time for Cause (as defined below) upon written notice to the Executive, in which event all payments under this Agreement shall cease, except for salary to the extent already accrued. The Executive shall be entitled to any benefits accrued and
due in accordance with the terms of any applicable benefit plans and programs of the Company. The Company hereby acknowledges that, as of the Effective Date, without independent investigation, it has no knowledge of any reason to terminate the
Executive’s employment for Cause. For purposes of this Agreement, “Cause” shall mean any of the following grounds for termination of the Executive’s employment: 
  
 (a) The Executive shall have been convicted of or pleads
nolo contendere to a felony; or 
  
 (b) Gross
negligence or willful misconduct in the performance of the Executive’s duties. 
  
 14. Change in Control. Upon the occurrence of a “change in control,” as defined in that certain change in control agreement between the Executive and the Company dated January 25, 1995 (the “CIC
Agreement”), during the Term, the terms and conditions of the CIC Agreement will supersede and replace the terms and conditions of this Agreement. 
  
 15. Restrictive Covenants. 
  
 (a) Non-Competition. During the Term and for the 12-month period beginning on the date the Executive’s employment terminates,
for any reason, other than in the case of the expiration of this Agreement at the end of the Term (the “Restriction Period”), the Executive hereby agrees that he will not, without the Company’s express written consent, engage
(directly or indirectly) in any employment or business activity whose primary business involves or is related to (directly or indirectly) providing mortgage insurance or financial guaranty to financial institutions located throughout the United
States of America and the World, or would otherwise conflict with the Executive’s employment by the Company (“Competing Employer”). Notwithstanding the foregoing, during the Restriction Period, the Executive may request permission
from the Board to accept employment with a Competing Employer, which such permission shall not be unreasonably withheld. 
  
 (b) Non-Solicitation and Non-Hire of Company Personnel. During the Term and for the Restriction Period, the Executive hereby agrees
that he will not either directly or through others, solicit, hire or attempt to solicit or hire any employee, consultant or independent contractor of the Company to change or terminate his or her relationship with the Company or otherwise to become
an employee, consultant or independent contractor to, for or of any other person or business entity, unless more than twelve months shall have elapsed between the last day of such person’s employment or service with the Company and the first
date of such solicitation or hiring or attempt to solicit or hire. 
  
 (c) Non-Solicitation of Customers. During the Term and for the Restriction Period, the Executive hereby agrees that he will not, either directly or through others, solicit, 

  

 5 

 
divert or appropriate, or attempt to solicit, divert or appropriate any customer or actively sought prospective customer of the Company for the purpose of
providing such customer or actively sought prospective customer with services or products competitive with those offered by the Company during the Term. 
  
 (d) Proprietary Information. At all times, the Executive will hold in strictest confidence and will not disclose, use, lecture upon
or publish any of the Company’s Proprietary Information (defined below), except as such disclosure, use or publication may be required in connection with the Executive’s work for the Company, or unless the Company expressly authorizes such
disclosure in writing or it is required by law or in a judicial or administrative proceeding in which event the Executive shall promptly notify the Company of the required disclosure and assist the Company if it determines to resist the disclosure.
“Proprietary Information” shall mean any and all confidential and/or proprietary knowledge, data or information of the Company, its affiliated entities, any of its portfolio companies, investors, and partners, including but not limited to
information relating to financial matters, investments, budgets, business plans, marketing plans, personnel matters, business contacts, products, processes, know-how, designs, methods, improvements, discoveries, inventions, ideas, data, programs,
and other works of authorship. Notwithstanding anything to the contrary herein, each of the parties hereto (and each employee, representative, or other agent of such parties) may disclose to any person, without limitation of any kind, the federal
income tax treatment and federal income tax structure of the transactions contemplated hereby and all materials (including opinions or other tax analyses) that are provided to such party relating to such tax treatment and tax structure. 

 
 (e) Return of Company Documents. Upon termination
of the Executive’s employment with the Company for any reason whatsoever, voluntarily or involuntarily, and at any earlier time the Company requests, the Executive will deliver to the person designated by the Company all originals and copies of
all documents and other property of the Company in the Executive’s possession, under the Executive’s control or to which the Executive may have access. The Executive will not reproduce or appropriate for the Executive’s own use, or
for the use of others, any property, Proprietary Information or Company Inventions. 
  
 16. Restrictions on Unsolicited Acquisition Activities. In consideration of the benefits provided by the Company to the Executive under this Agreement, the Executive agrees that, during the Term and for the
Restriction Period, without the prior written consent of the Board, the Executive shall not (directly or indirectly or through one or more intermediaries) (a) purchase, offer or agree to purchase, or announce an intention to purchase, directly or
indirectly, any voting securities or assets of the Company in excess of 5% of the outstanding common stock of the Company; (b) make, or in any way participate, directly or indirectly, in any “solicitation” of “proxies” to vote or
“consents” (as such terms are used in the rules and regulations of the Securities and Exchange Commission) or seek to advise or influence any person with respect to the voting of any voting securities of the Company or any subsidiary
thereof; (c) initiate or support, directly or indirectly, any stockholder proposal with respect to the Company; (d) directly or indirectly make any public announcement with respect to, or submit a proposal for, or offer of (with or without
conditions) any extraordinary transaction involving the Company or its securities or assets or any subsidiary thereof, or of any successor to or person in control of the Company or any of its businesses, or any assets of the Company or any
subsidiary or division 

  

 6 

 
thereof or of any such successor or controlling person; (e) seek or propose to influence or control the Company’s management or policies; (f) seek to
negotiate or influence the terms and conditions of employment of employees of the Company or any agreement of collective bargaining with employees of the Company or (g) form, join or in any way participate in a “group” as defined in
Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) in connection with any of the foregoing; provided, however, that the terms of subsections (b), (c), (e) and (f) shall exclude actions taken by the
Executive in connection with his fiduciary duties as an officer or director of the Company. Nothing contained herein shall restrict the Executive from making a cash tender offer for all of the outstanding capital stock of the Company after such time
as both (i) a third party has commenced, within the meaning of Rule 14d-2 of the Exchange Act, a cash tender offer for the capital stock of the Company at a lower price and (ii) the Company has recommended to its stockholders that they accept such
offer. Notwithstanding the foregoing, in the event of a bona fide offer from a third party, the Executive may request that the Company waive the restrictions set forth in this Section 16, which consent to such waiver request shall not be
unreasonably withheld. 
  
 17. Legal and Equitable
Remedies. Because the Executive’s services are personal and unique and the Executive has had and will continue to have access to and has become and will continue to become acquainted with the Proprietary Information of the Company_ and
because any breach by the Executive of any of the restrictive covenants contained in Sections 15 and 16 would result in irreparable injury and damage for which money damages would not provide an adequate remedy, the Company shall have the right to
enforce Sections 15 and 16 and any of their provisions by injunction, specific performance or other equitable relief, without bond and without prejudice to any other rights and remedies that the Company may have for a breach, or threatened breach,
of the restrictive covenants set forth in Sections 15 and 16. The Executive agrees that in any action in which the Company seeks injunction, specific performance or other equitable relief, the Executive will not assert or contend that any of the
provisions of Section 15 or 16 are unreasonable or otherwise unenforceable. The Executive irrevocably and unconditionally (i) agrees that any legal proceeding arising out of this paragraph may be brought in the United States District Court for the
Eastern District of Pennsylvania, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in Philadelphia County, Pennsylvania, (ii) consents to the non-exclusive jurisdiction of such court
in any such proceeding, and (iii) waives any objection to the laying of venue of any such proceeding in any such court. The Executive also irrevocably and unconditionally consents to the service of any process, pleadings, notices or other papers.

  
 18. Survival. The provisions of Sections 8, 15, 16 and
17 shall survive the termination of this Agreement; provided, however, that in the event the Agreement expires at the end of the Term only Section 8 shall survive. 
  
 19. No Mitigation or Set Off. In no event shall the Executive be obligated to seek other employment or take any other
action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and such amounts shall not be reduced, regardless of whether the Executive obtains other employment. The Company’s obligation to
make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any circumstances, including, without limitation, any set-off, 

  

 7 

 
counterclaim, recoupment, defense or other right which the Company may have against the Executive or others. 
  
 20. Notices. All notices and other communications required or
permitted under this Agreement or necessary or convenient in connection herewith shall be in writing and shall be deemed to have been given when hand delivered or mailed by registered or certified mail, as follows (provided that notice of change of

Waiver. No remedy conferred upon a party by this Agreement is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to any other remedy given under this Agreement or now or
hereafter existing at law or in equity. No delay or omission by a party in exercising any right, remedy or power under this Agreement or existing at law or in equity shall be construed as a waiver thereof, and any such right, remedy or power may be
exercised by such party from time to time and as often as may be deemed expedient or necessary by such party in its sole discretion. 
  
 23. Assignment. All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the
respective heirs, executors, administrators, legal representatives, successors and assigns of the parties hereto, except that the duties and responsibilities of the Executive under this Agreement are of a personal nature and shall not be assignable
or delegable in whole or in part by the Executive. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all of the business or assets of the
Company, within 15 days of such succession, expressly to assume and agree to perform this Agreement in the same manner and to the same extent as the Company would be required to perform if no such succession had taken place and the Executive
acknowledges that in such event the obligations of the Executive hereunder, including but not limited to those under Sections 15 and 16, will continue to apply in favor of the successor. 
  
 24. Entire Agreement. This Agreement sets forth the entire agreement of the parties hereto and supersedes any and all
prior agreements and understandings concerning the Executive’s employment by the Company. This Agreement may be changed only by a written document signed by the Executive and the Company. 
  
 25. Severability. If any provision of this Agreement or application
thereof to anyone or under any circumstances is adjudicated to be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect any other provision or application of this Agreement which can be given effect
without the invalid or unenforceable provision or application and shall not invalidate or render unenforceable such provision or application in any other jurisdiction. If any provision is held void, invalid or unenforceable with respect to
particular circumstances, it shall nevertheless remain in full force and effect in all other circumstances. 
  
 26. Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the substantive and procedural laws of the
Commonwealth of Pennsylvania without regard to rules governing conflicts of law.

 EXHIBIT A 
  
 GENERAL RELEASE 
  
 1. I, Frank P. Filipps, for and in consideration of (i) certain payments to be made and the benefits to be provided to me under the Employment Agreement,
dated as of November 11, 2003 (the “Agreement”) with Radian Group lnc. (the “Company”) and (ii) the Company’s execution of a release in my favor, on the date this General Release becomes irrevocable, substantially in the
form attached as an Annex hereto, and conditioned upon such payments and provisions, do hereby REMISE, RELEASE, AND FOREVER DISCHARGE the Company and each of its past or present subsidiaries and affiliates, its and their past or present

the past or present trustees, administrators, agents, or employees of the pension and employee benefit plans (hereinafter collectively included within the term the “Company”), acting in any capacity whatsoever, of and from any and all
manner of actions and causes of actions, suits, debts, claims and demands whatsoever in law or in equity, which I ever had, now have, or hereafter may have, or which my heirs, executors or administrators hereafter may have, by reason of any matter,
cause or thing whatsoever from the beginning of my employment with the Company to the date of these presents and particularly, but without limitation of the foregoing general terms, any claims arising from or relating in any way to my employment
relationship and the termination of my employment relationship with the Company, including but not limited to, any claims which have been asserted, could have been asserted, or could be asserted now or in the future under any federal, state or local
laws, including any claims under the Pennsylvania Human Relations Act, 43 PA. C.S.A. §§ 951 et seq., as amended, the Rehabilitation Act of 1973. 29 USC §§ 701 et seq., as amended, Title VII of the Civil Rights Act of 1964, 42 USC

and all claims for counsel fees and costs; provided, however, that this Release shall not apply to any entitlements under the terms of the Agreement or under any other plans or programs of the Company in which I participated and under which I have
accrued and become entitled to a benefit other than under any Company separation or severance plan or programs and provided, further, that this Release shall not apply to any claims I may have as a stockholder of the Company so long as I am not the
moving, initiating or lead party. 
  
 2. Subject to the
limitations of paragraph 1 above, I expressly waive all rights afforded by any statute which expressly limits the effect of a release with respect to unknown claims. I understand the significance of this release of unknown claims and the waiver of
statutory protection against a release of unknown claims. 
  
 3. I
hereby agree and recognize that my employment by the Company was permanently and irrevocably severed on                     ,
20     and the Company has no obligation, contractual or otherwise to me to hire, rehire or reemploy me in the future. I 

  

 11
