 GUARANTY

 GUARANTY, dated as of September 28, 2022 (as amended, restated, supplemented, or otherwise modified from time to time, this
“Guaranty”), made by Radian Group Inc., a Delaware corporation (the “Guarantor”), in favor of Bank of Montreal, a Canadian Chartered bank acting through its Chicago Branch (the “Buyer”). 

RECITALS 
 Pursuant to the
Master Repurchase Agreement and Securities Contract, dated as of September 28, 2022 (as amended, restated, supplemented or otherwise modified from time to time, the “Repurchase Agreement”), between Radian Mortgage Capital LLC
(the “Seller”) and the Buyer, the Buyer has agreed from time to time to enter into Transactions (as defined in the Repurchase Agreement) with Seller upon the terms and subject to the conditions set forth therein. It is a condition
precedent to the obligation of the Buyer to enter into Transactions with the Seller under the Repurchase Agreement, that the Guarantor shall have executed and delivered this Guaranty to the Buyer. 

NOW, THEREFORE, in consideration of the premises and to induce the Buyer to enter into the Repurchase Agreement and engage in Transactions
with the Seller, and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the Guarantor hereby agrees to guarantee the Seller’s obligations under the Repurchase Agreement, as may be amended from
time to time. 
 1. Defined Terms. 

(a) Unless otherwise defined herein, terms defined in the Repurchase Agreement and used herein shall have the meanings given to them in the
Repurchase Agreement. 
 (b) For purposes of this Guaranty, “Disqualified Capital Stock” shall mean any equity interest
which, by its terms (or by the terms of any security into which it is convertible or for which it is exchangeable), or upon the happening of any event, (a) matures (excluding any maturity as the result of an optional redemption by the issuer
thereof) or is mandatorily redeemable, pursuant to a sinking fund obligation or otherwise, or is redeemable at the option of the holder thereof, in whole or in part, on or prior to the date that
is ninety-one (91) days after the Termination Date, (b) is convertible into or exchangeable (unless at the sole option of the issuer thereof) for (i) debt securities or (ii) any
equity interest referred to in clause (a) above, in each case at any time on or prior to date that is ninety-one (91) days after the termination of the Repurchase Agreement, or
(c) contains any repurchase obligation which may come into effect prior to payment in full of all Obligations; provided, however, that (x) any equity interest that would not constitute Disqualified Capital Stock
but for provisions thereof giving holders thereof (or the holders of any security into or for which such equity interest is convertible, exchangeable or exercisable) the right to require the issuer thereof to redeem such equity interest upon the
occurrence of a change in control or an asset sale occurring prior to the date that is ninety-one (91) days after the termination of the Repurchase Agreement shall not constitute Disqualified Capital
Stock if such equity interest provides that the issuer thereof will not redeem any such equity interest pursuant to such provisions 

 
prior to the repayment in full of the Obligations, and (y) if such equity interest is issued to any employee or to any Plan for the benefit of employees of the Guarantor or the Subsidiaries
or by any such Plan to such employees, such equity interest shall not constitute Disqualified Capital Stock solely because it may be required to be repurchased by the Guarantor or any Subsidiary in order to satisfy applicable compulsory statutory or
regulatory obligations or as a result of such employee’s termination, death or disability. 
 (c) For purposes of this Guaranty,
“Obligations” shall mean all payment obligations and liabilities of the Seller to the Buyer, whether direct or indirect, absolute or contingent, due or to become due, or now existing or hereafter incurred, or whether for payment
(including, without limitation, Price Differential accruing after the Repurchase Date for the Transactions and Price Differential accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding, relating to the Seller, whether or not a claim for post filing or post petition interest is allowed in such proceeding), which may arise under, or out of or in connection with the Repurchase Agreement, this Guaranty and any other
Facility Documents, whether on account of principal, interest, reimbursement obligations, fees, indemnities, costs, expenses (including, without limitation, all reasonable and documented fees and disbursements of outside counsel to the Buyer that
are required to be paid by the Seller pursuant to the terms of the Facility Documents), all “claims” (as defined in Section 101 of the Bankruptcy Code) of the Buyer against the Seller under the Facility Documents. 

(d) For purposes of this Guaranty, “Investment” in any Person, means (a) any loan, advance (other than commission, travel
and similar advances to officers and employees made in the ordinary course of business), extension of credit (other than accounts receivable, debit and credit card receivables and advances to customers (including premium receivables) and third party
servicers arising in the ordinary course of business) or capital contribution by such Person; and (b) any purchase by such Person of stocks, bonds, mutual funds, partnership interests, notes, debentures or other securities (including warrants
or options to purchase securities) 
 (e) The words “hereof,” “herein” and “hereunder” and words of similar
import when used in this Guaranty shall refer to this Guaranty as a whole and not to any particular provision of this Guaranty, and section and paragraph references are to this Guaranty unless otherwise specified. 

(f) The meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms. 

2. Guarantee. (a) Guarantor hereby, unconditionally and irrevocably, guarantees to the Buyer and its successors, indorsees,
transferees and assigns, the prompt and complete payment and performance by the Seller when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations. 

(b) Guarantor further agrees to pay any and all documented
out-of-pocket expenses (including, without limitation, all reasonable and documented fees and disbursements of outside counsel) which may be paid or incurred by the
Buyer in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or collecting, any or all of the Obligations and/or enforcing any rights with respect to, or collecting against, the Guarantor under this Guaranty. This
Guaranty shall remain in full force and effect until the later of (i) the termination of the Repurchase Agreement or (ii) the Obligations are paid in full, notwithstanding that from time to time prior thereto the Seller may be free from
any Obligations. 

  
 -2- 

 (c) No payment or payments made by the Seller, the Guarantor, any other guarantor or any
other Person or received or collected by the Buyer from the Seller, the Guarantor, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application
at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the Guarantor hereunder which shall, notwithstanding any such payment or payments other
than payments made by the Guarantor in respect of the Obligations or payments received or collected from the Guarantor in respect of the Obligations, remain liable for the Obligations until the Obligations are paid in full and the Repurchase
Agreement is terminated subject to the provisions thereof. 
 (d) Guarantor agrees that whenever, at any time, or from time to time, the
Guarantor shall make any payment to the Buyer on account of the Guarantor’s liability hereunder, the Guarantor will notify the Buyer in writing that such payment is made under this Guaranty for such purpose. 

3. Right of Set-off. Upon the occurrence of any Event of Default, the Guarantor hereby
irrevocably authorizes the Buyer at any time and from time to time without notice to the Guarantor, any such notice being expressly waived by the Guarantor, to set-off and appropriate and apply any and all
monies and other property of the Guarantor, deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by the Buyer or any Affiliate thereof to or for the credit or the account of the Guarantor, or any part thereof in such amounts as the Buyer may elect, against and on account of the
Obligations and liabilities of the Guarantor to the Buyer hereunder and claims of every nature and description of the Buyer against the Guarantor, in any currency, whether arising hereunder, under the Repurchase Agreement, or otherwise, as the Buyer
may elect, whether or not the Buyer has made any demand for payment and although such Obligations and liabilities and claims may be contingent or unmatured; provided, however, that the aforesaid right to
set-off shall not apply to any deposits of escrow monies being held on behalf of the Mortgagors related to the Purchased Mortgage Loans or other third parties. Notwithstanding the foregoing or anything to the
contrary contained elsewhere herein or in any Facility Document, if Guarantor, Seller or any of their respective Affiliates (each such entity, a “Guarantor Entity”) owes any obligation to Buyer or any Affiliate thereof (each such
entity, a “Buyer Entity”), such Buyer Entity may aggregate, setoff and net: (i) any collateral pledged by any Guarantor Entity to any Buyer Entity or held or carried for any Guarantor Entity by any Buyer Entity; and
(ii) any collateral required to be paid or returned by any Guarantor Entity to any Buyer Entity. The Buyer shall notify the Guarantor promptly of any such set-off permitted under this Section and the
application made by the Buyer; provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Buyer under this Section are in addition to
other rights and remedies (including, without limitation, other rights of set-off) which the Buyer may have. 

  
 -3- 

 4. No Subrogation. Notwithstanding any payment or payments made by the Guarantor
hereunder or any set-off or application of funds of the Guarantor by the Buyer, the Guarantor shall not be entitled to be subrogated to any of the rights of the Buyer against the Seller or any other guarantor
or any collateral security or guarantee or right of offset held by the Buyer for the payment of the Obligations, nor shall the Guarantor seek or be entitled to seek any contribution or reimbursement from the Seller or any other guarantor in respect
of payments made by the Guarantor hereunder, until all amounts owing to the Buyer by the Seller on account of the Obligations are paid in full and the Repurchase Agreement is terminated. The Guarantor hereby subordinates all of its subrogation
rights against Seller to the full payment of Obligations due Buyer under the Repurchase Agreement for a period of ninety-one (91) days following the final payment of the last of all of the Obligations
under the Facility Documents. If any amount shall be paid to the Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by the Guarantor in trust for the
Buyer, segregated from other funds of the Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned over to the Buyer in the exact form received by the Guarantor (duly indorsed by the Guarantor to the Buyer, if required), to be
applied against the Obligations, whether matured or unmatured, in such order as the Buyer may determine. 
 5. Amendments, Etc. with
Respect to the Obligations; Waiver of Rights. Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against the Guarantor and without notice to or further assent by the Guarantor, any demand for
payment of any of the Obligations made by the Buyer may be rescinded by the Buyer and any of the Obligations continued, and the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee
therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Buyer, and the Repurchase Agreement, and the
other Facility Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Buyer may deem advisable from time to time, and any collateral
security, guarantee or right of offset at any time held by the Buyer for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. The Buyer shall not have any obligation to protect, secure, perfect or insure any lien
at any time held by it as security for the Obligations or for this Guaranty or any property subject thereto. When making any demand hereunder against the Guarantor, the Buyer may, but shall be under no obligation to, make a similar demand on the
Seller or any other guarantor, and any failure by the Buyer to make any such demand or to collect any payments from the Seller or any such other guarantor or any release of the Seller or such other guarantor shall not relieve the Guarantor of its
obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Buyer against the Guarantor. For the purposes hereof “demand” shall include the commencement
and continuance of any legal proceedings. 
 6. Guaranty Absolute and Unconditional. 

(a) Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of
reliance by the Buyer upon this Guaranty or acceptance of this Guaranty, the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this

or nonpayment to or upon the Seller or the Guarantor, surrender or other handling or disposition of assets subject to the Repurchase Agreement, any requirement that Buyer exhaust any right, power or remedy or take any action against the Seller or
against any assets subject to the Repurchase Agreement, and other formalities of any kind. 
 (c) Guarantor understands and agrees that this
Guaranty shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (i) the validity, regularity or enforceability of the Repurchase Agreement, any of the Obligations or any other collateral security
therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Buyer, (ii) any defense, set-off or counterclaim (other than a defense of payment or performance)
which may at any time be available to or be asserted by the Seller against the Buyer, or (iii) any other circumstance whatsoever (with or without notice to or knowledge of the Seller or the Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Seller from the Obligations, or of the Guarantor from this Guaranty, in bankruptcy or in any other instance. 

(d) When pursuing its rights and remedies hereunder against the Guarantor, the Buyer may, but shall be under no obligation to, pursue such
rights and remedies as it may have against the Seller or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Buyer to pursue such other rights or
remedies or to collect any payments from the Seller or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Seller or any such other Person or any such
collateral security, guarantee or right of offset, shall not relieve the Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Buyer against the
Guarantor. 
 (e) This Guaranty shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon
the Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Buyer, and its successors, indorsees, transferees and assigns, until all the Obligations and the obligations of the Guarantor under this Guaranty shall have
been satisfied by payment in full and the Repurchase Agreement shall be terminated, notwithstanding that from time to time prior thereto the Seller may be free from any Obligations. 

(f) Guarantor waives, to the fullest extent permitted by applicable law, all defenses of surety to which it may be entitled by statute or
otherwise.

directly or indirectly, whether in cash or property or in obligations of Guarantor or any of Guarantor’s consolidated Subsidiaries (any such payment or dividend, a “Restricted Payment”); provided, however, that
the following Restricted Payments shall be permitted after the occurrence and continuance of an Event of Default: (a) any Restricted Payment made by a Subsidiary to the Guarantor, to any wholly owned Subsidiary of the Guarantor or to holders of
its equity interests on a ratable basis, (b) the Guarantor may make Restricted Payments payable solely in additional shares of its equity interests (other than Disqualified Capital Stock), (c) the Guarantor may make Restricted Payments in
the form of (i) equity pursuant to and in accordance with stock option plans or other benefit plans for directors or employees of the Guarantor and its Subsidiaries, (ii) the cashless purchase of shares of its equity interests awarded
under such plans from such employees to offset tax liabilities and the payment of any taxes associated with the vesting of such shares and (iii) cash to settle and terminate equity interests under such plans, (d) the Guarantor may make any
Restricted Payment within sixty (60) days after the date of declaration thereof, if on the date of declaration there is no Event of Default; provided, that no such Restricted Payment may be made if at the time of such declaration, a
Responsible Officer of Guarantor has knowledge that a Material Adverse Effect has occurred, is reasonably likely to occur or will result therefrom, and (e) the Guarantor or any Subsidiary may make regular quarterly dividends so long as no Event
of Default shall exist, as determined on the date such dividends are declared. For the avoidance of doubt, no Restricted Payment may be made if an Event of Default would result therefrom. 

(i) ERISA Matters. 

(i) Guarantor shall not permit any event or condition which is described in any of clauses (i) through (x) of the
definition of “Event of ERISA Termination” to occur or exist with respect to any Plan or Multiemployer Plan if such event or condition, together with all other events or conditions described in the definition of Event of ERISA Termination
occurring within the prior twelve (12) months, involves the payment of money by or an incurrence of liability of Guarantor or any ERISA Affiliate thereof, or any combination of such entities in an amount in excess of $500,000. 

(ii) Guarantor shall not be an employee benefit plan as defined in Section 3(3) of Title I of ERISA, or a plan described

 -12- 

 (j) Transactions with Affiliates. Guarantor shall not enter into any transaction,

the ordinary course of Guarantor’s business, (c) upon fair and reasonable terms no less favorable to Guarantor, as the case may be, than it would obtain in a comparable arm’s length transaction with a Person which is not an Affiliate,
(d) is among Guarantor and one or more of its direct or indirect wholly-owned Subsidiaries; provided, that, such transaction is entered into on an arm’s length basis, (e) constitutes normal and reasonable compensation and
reimbursement of expenses of officers and directors in the ordinary course of Guarantor’s business, (f) such transaction constitutes payment of reasonable and customary fees and reasonable out of pocket costs to, and indemnities provided
to or on behalf of, directors, officers and consultants, (g) such transaction constitutes payment of any dividend or other distribution (whether in cash, securities or other Property) with respect to any equity interest in the Guarantor or any
of its Subsidiaries or any payment (whether in cash, securities or other Property), including any sinking fund or similar deposit, on account of the purchase, redemption, retirement, acquisition, cancellation or termination of any such equity
interests in the Guarantor or any Subsidiary thereof or any option, warrant or other right to acquire any such equity interest in Guarantor or any Subsidiary thereof (it being understood that Indebtedness convertible into an equity interest of the
Guarantor or any Subsidiary is not an equity interest), (h) such transaction constitutes an Investment which is consented to by Buyer or otherwise agreed to in writing between Buyer and Guarantor, or (i) such transaction is consented to by
Buyer or otherwise agreed to in writing between Buyer and Guarantor. 
 (k) More Favorable Agreement. Guarantor agrees that if as of
the Effective Date, Guarantor has entered into, or if at any time following the Effective Date either Guarantor enters into, a repurchase agreement, warehouse facility, guaranty or similar credit facility with any Person which by its terms provides
more favorable terms with respect to any of the financial covenants hereunder or any of the items covered in Section 9(h) hereof, then the terms of this Guaranty shall be deemed automatically amended to include such more favorable terms, such
that such terms operate in favor of Buyer. Guarantor further agrees to execute and deliver any new agreements or amendments to this Guaranty evidencing such provisions, provided that the execution of such amendment shall not be a precondition to the
effectiveness of such amendment, but shall merely be for the convenience of the parties thereto. Promptly upon either Guarantor thereof entering into a repurchase agreement, warehouse facility, guaranty or similar credit facility or other credit
facility with any Person other Buyer, Guarantor shall deliver to Buyer a true, correct and complete copy of each financial covenant contained in such repurchase agreement, loan agreement, guaranty or other financing documentation. 

10. Payments. Guarantor hereby guarantees that payments hereunder will be paid to the Buyer without
set-off or counterclaim in U.S. Dollars. 
 11. Event of Default. If an Event of Default under
the Repurchase Agreement shall have occurred and be continuing, the Guarantor agrees that, as between the Guarantor and Buyer, the Obligations may be declared to be due for purposes of this Guaranty notwithstanding any stay, injunction or other
prohibition which may prevent, delay or vitiate any such declaration as against Seller and that, in the event of any such declaration (or attempted declaration), such Obligations shall forthwith become due by the Guarantor for purposes of this
Guaranty. 

  
 -13- 

 12. Waiver of Rights. Guarantor hereby waives: (i) notice of or proof of
reliance by the Buyer upon this Guaranty or acceptance of this Guaranty and the Obligations shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this Guaranty, and all
dealings between the Seller and the Guarantor, on the one hand, and the Buyer, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon this Guaranty; (ii) diligence, presentment, protest, all
demands whatsoever, and notice of default or nonpayment with respect to the Obligations; (iii) the filing of claims with any court in case of the insolvency, reorganization or bankruptcy of the Seller; and (iv) any fact, event or
circumstance that might otherwise constitute a legal or equitable defense to or discharge of the Guarantor, including (but without typifying or limiting this waiver), failure by the Buyer to perfect a security interest in any collateral securing
performance of any Obligation or to realize the value of any collateral or other assets which may be available to satisfy any Obligation and any delay by the Buyer in exercising any of its rights hereunder or against the Seller. 

13. Notices. Notices by Buyer to the Guarantor shall be given in accordance with Section 26 of the Repurchase Agreement. 

14. Severability. Each provision and agreement herein shall be treated as separate and independent from any other provision or agreement

16. Amendments in Writing; No Waiver; Cumulative Remedies. (a) None of the terms or provisions of this Guaranty may be waived,
amended, supplemented or otherwise modified except by a written instrument executed by the Guarantor and the Buyer, provided that any provision of this Guaranty may be waived by the Buyer. 

(b) The Buyer shall not by any act (except by a written instrument pursuant to Section 16(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising,
on the part of the Buyer, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. A waiver by the Buyer of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Buyer would otherwise have on any future occasion. 

(c) The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights
or remedies provided by law. 
 17. Section Headings. The section headings used in this Guaranty are for convenience of reference only

related Guaranty, dated as of September 28, 2022 (as amended, restated, supplemented or otherwise modified from time to time, the “Guaranty”) made by Radian Group Inc. (the “Guarantor”) for the benefit of the
Buyer, Guarantor covenants on and as of the date of the Guaranty, each Purchase Date and on each day until the Guaranty is no longer in force, and in addition to the covenants set forth in Section 16 of the Guaranty, as
follows: 
  

	 	(a)	 Total Adjusted Capital. Guarantor shall not permit the Total Adjusted Capital of Radian Guaranty, Inc.
and Radian Reinsurance, Inc. as of the end of any Test Period to be less than $3,000,000,000. 

  

	 	(b)	 Consolidated Net Worth. Guarantor shall not permit its Consolidated Net Worth as of the last day of any
Test Period to be less than the sum of (i) $2,750,000,000, plus (ii) 50% of the positive amount, if any, of the cumulative Consolidated Net Income (loss) of Guarantor and its Subsidiaries after the Effective Date (the “Reference
Date”), plus (iii) 50% of the aggregate amount of all equity contributions to, or equity issuances of, the Guarantor after the Reference Date. For the purpose of applying clause (iii) of the immediately preceding sentence to any equity
issuance by the Guarantor in respect of the conversion, settlement, repurchase or other retirement of any convertible notes, if any, issued after the date hereof by Guarantor, the amount of such equity issuance will be the increase (if any) in the
Guarantor’s consolidated shareholders’ equity recorded in respect of such conversion, settlement, repurchase or other retirement, and such equity issuance shall result in the addition of an amount equal to 50% of the amount of such
increase pursuant to such clause (iii) at the time such increase is recorded; provided, however, that if any repurchase by the Guarantor of any common shareholder interests of the Guarantor within
one-hundred eighty (180) days of such conversion, settlement, repurchase or other retirement results in the Guarantor recording a reduction of its consolidated shareholders’ equity, then the amount
initially added pursuant to such clause (iii) in respect of such conversion, settlement, repurchase or other retirement shall be reduced (but not below zero) by an amount equal to 50% of the amount of such reduction at the time such reduction
is recorded. 

  

	 	(c)	 Debt-to-Total Capitalization
Ratio. Guarantor shall not permit the Debt-to-Total Capitalization Ratio of the Guarantor as of the end of any Test Period to exceed 0.35:1.

regulatory department, authority or agency that may be created and that asserts insurance regulatory jurisdiction over such Regulated Insurance Company, but shall not include any Freddie Mac, Fannie Mae, the Federal Housing Finance Agency, and any

statements in accordance with GAAP, whether or not such obligation is guaranteed in whole or in part by the Guarantor and/or any Subsidiary and whether or not such obligation is with recourse to the Guarantor and/or any Subsidiary, provided that the
proceeds of such obligation are used by such special purpose entity or trust to make loans to, or to purchase assets from, the Guarantor, any Subsidiary or any Affiliate of the Guarantor or any Subsidiary, or other Person, in the ordinary course of
business (it being understood that securitization and similar transactions involving special purpose entities or trusts established by the Guarantor or any Subsidiary are in the ordinary course of business).

aggregate write-ins for liabilities on page 3, line 25, column 1 of the most recent financial statement of such Regulated Insurance Company and as reported as “Contingency reserve” in the

determinable amount of the primary obligation in respect of which such Contingent Obligation is made and (ii) the maximum amount for which such guaranteeing person may be liable pursuant to the terms of the instrument embodying such Contingent
Obligation, unless such primary obligation and the maximum amount for which such guaranteeing person may be liable are not stated or determinable, in which case the amount of such Contingent Obligation shall be such guaranteeing person’s
maximum reasonably anticipated liability in respect thereof as determined by the Guarantor in good faith.

(i) obligations for borrowed money, (ii) obligations representing the deferred purchase price of Property or services (other than accounts payable and accrued expenses, in each case, arising in the ordinary course of business),

respect to letters of credit, (viii) Contingent Obligations of such Person in respect of Debt of any other Person, (ix) the liquidation value of all mandatorily redeemable preferred equity interests of such Person and
(x) Securitization Indebtedness. Notwithstanding the foregoing, the term “Debt” shall exclude (1) purchase price adjustments, earnouts, holdbacks or deferred payments of a similar nature (including deferred compensation
representing consideration or other contingent obligations incurred in connection with an Acquisition), except in each case to the extent that such amount payable is, or becomes, reasonably determinable and contingencies have been resolved,
(2) indebtedness that has been defeased and/or discharged in accordance with its terms; provided that funds in an amount equal to all such indebtedness (including interest and any other amounts required to be paid to the holders
thereof in order to give effect to such defeasance and/or discharge) have been irrevocably deposited with a trustee for the benefit of the relevant holders of such indebtedness, (3) accrued pension costs, employee benefits and postretirement
health care obligations arising in the ordinary course of business, (4) obligations in respect of customer advances (including prepaid premiums) received and held in the ordinary course of business, (5) any Debt to Federal Home Loan Bank,

  Campus Martinsried Fraunhoferstrasse 9a 82152 Martinsried/Munich Deutschland/Germany

    

    

  (hereinafter the "Company")

    

  represented by its Supervisory Board,

  which again is represented by its chairman, Mr. Nikos Theodosopoulos

    

    

    

  and

    

  Mr. Brian L. Protiva

    

  Assenbucher Strasse 28

  82335 Berg 

   

  (hereinafter, “Mr. Protiva")

  (the Company and Mr. Protiva together hereinafter also the "Parties")

    

  Preamble

    

  Mr. Protiva has been a member of the management board and CEO of the Company since March 1999. Mr. Protiva rendered his services based on the board member service contract dated 6th March 1999 (hereinafter the "Service Contract") which has been extended in accordance with the renewals of Mr. Protiva's term of office as board member ever since. Both, the current term of office and the Service Contract, will expire as of 31 December 2022.

    

  The Company has entered into a business combination agreement with Adtran Inc. according to which the Company and Adtran will combine under a new holding company, namely Adtran Holdings, Inc. It is envisaged that Mr. Protiva assumes the role as Vice Chairman of the Board of Adtran Holdings, Inc. which, upon closing of the transaction, will become the majority stockholder of the Company. In this context, the Supervisory Board of the Company and Mr. Protiva agreed that Mr. Protiva should step down from his office as member of the Company's management board.

    

  This said, the Parties have agreed on the following:

    

  1.RESIGNATION FROM OFFICE AS CEO AND BORD MEMBER

  b.Mr. Protiva will continue to properly perform his services as CEO and member of the Company's management board up to the Resignation Date and will ensure that his official duties are properly handed over to a successor. In addition, Mr. Protiva will continue to

  be available to the Company's management board to answer questions on business matters of the Company during the release period pursuant to section 2.2 below until the Termination Date and for a period of 14 days following release of the Company's 2022 Annual Report.

    

  2.SETTLEMENT

    

  a.The Parties are in agreement that the Service Contract ends automatically as of 31 December 2022 ('Termination Date"), without any notice of termination being required. For the sake of clarification: Mr. Protiva shall continue to receive his remuneration as CEO until the Termination Date, including his monthly fix remuneration as well as the STI and the LTl subject to their terms, but shall not be entitled to any severance payment as compensation for the expiry of his Service Contract.

  b.The Company shall irrevocably release Mr. Protiva from his service obligation under the Service Contract with effect from the Resignation Date, with continued payment of the contractually agreed remuneration until the Termination Date.

  c.The contractual obligation of confidentiality, the contractual prohibition of side activities and the contractual obligation of non-compete continue to apply until the Termination Date. Mr. Protiva is explicitly allowed to render services as Vice Chairman of the Board of Adtran Holdings Section 615 sentence 2 of the German Commercial Code [BOrgerliches Gesetzbuch -8GB].

  3.RETURN OF ITEMS/ COMPANY CAR/ EMAIL-ACCOUNT

    

  a.Mr. Protiva shall, unless he has already done so, return to the Company, in full and undamaged, all items that belong to the Company or were provided to Mr. Protiva by the Company or by a third party on behalf of the Company at the latest on the Termination Date. However, Mr. Protiva may keep his Company laptop and mobile phone until the longer of either (i) the expiration of the transition period pursuant to section 1.2 above or (ii) eight (8) weeks after the last requests for information by the Company.

    

  b.Furthermore, even though it is understood that Mr. Protiva worked in the digital domain, Mr. Protiva shall, unless he has already done so, return to the Company in full all documents (in particular memoranda, customer lists, drawings, sketches or any documents that address confidential information) that belong to the Company or were provided to Mr. Protiva by the Company or by a third party on behalf of the Company or that relate to the Company and/or have been created in connection with Mr. Protiva's work without undue delay, at the latest on the Termination Date.

  5

  

   

    

  to section 3.1. Mr. Protiva shall disclose to the Company any passwords, PIN codes and access blocks regarding IT systems that may only be known to Mr. Protiva and shall no longer use them himself.

  c.Mr. Protiva may continue to use the company car provided, Audi e-tron until the Termination Date to the existing extent and subject to the existing conditions. The company car, including accessories, shall be returned to the Company in due and proper condition by the Termination Date at the latest.

  d.Mr. Protiva will make an effort to delete all private email correspondence in his email account and consents to an access to such account by the Company for good reason pertaining to normal business activities and by the Company's General Counsel.

  e.The Company shall allow Mr. Protiva to review documents and electronically stored data of the Company even after the Termination Date, insofar as this is necessary for the purposes of legal defense. A necessary "legal defense" in this sense shall be at hand if and to the extent that claims are asserted against Mr. Protiva under civil or criminal law with regard to his activities as a member of the of the Company's management board, or if Mr. Protiva can show that such a claim is likely to be asserted. Disclosure of confidential documents and data to third parties is only permitted to the extent necessary for the purpose of legal defense. Upon request by the Company, Mr. Protiva shall provide information on to whom and to what extent such disclosure has been made.

    

  4.CONFIDENTIALITY

    

  a.Even after the service relationship is terminated, Mr. Protiva remains obliged to maintain strict secrecy in respect of all confidential matters, of the Company and its affiliated companies which became known to him in connection with his activity and not to disclose or pass them on to third parties. Confidential shall mean all matters which the Company has designated as such in writing or orally or which are obviously recognizable as such even without such designation. There shall be no duty of confidentiality

  i.for confidential matters that were publicly available at the time of disclosure;

    

  ii.insofar as the Mr. Protiva is obliged to disclose the confidential matter on the basis of a law or the decision of a court or administrative authority;

  iii.in the cases of sec. 5 of the German Business Secrets Act [Gesetz zum Schutz von Geschaftsgeheimnissen- GeschGehG].

    

  b.Disclosure of confidential matters with regard to which there is a duty of confidentiality under section 4.1, without the consent of the Company, may result in damages claims by the Company as well as in sanctions under service and criminal law.

  5.FINAL PROVISIONS

    

  a.No oral side agreements exist. Amendments or additions to this Settlement Agreement, including to this provision, require written form to be valid unless it can be proven that they have been individually agreed between the Parties.

  b.This Settlement Agreement is subject to German law.

    

  c.Should any provision of this Settlement Agreement be or become invalid in whole or in part, the validity of the remaining provisions of this Settlement Agreement will not be affected thereby. If a provision is found to be invalid, the Parties undertake to negotiate a

    

  /s/ BP

  valid and reasonable replacement provision that comes closest to the economic purpose pursued by the invalid provision. The same applies in case of a contractual gap.
