Exhibit 10.4

CONTINUING GUARANTY

FOR VALUE RECEIVED, the sufficiency of which is hereby acknowledged, and in consideration of credit and/or financial accommodations heretofore or hereafter from time to time made or granted to PROSPECT MEDICAL HOLDINGS, INC., a Delaware corporation (the “Borrower”), pursuant to the Credit Agreement dated as of the date hereof by and among the Borrower, ROYAL BANK OF CANADA as administrative agent (the “Administrative Agent”) and the lenders party thereto (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms not otherwise defined in this Guaranty shall have the respective meanings set forth in the Credit Agreement), the undersigned Guarantor (whether one or more, the “Guarantor”, and if more than one, jointly and severally) hereby furnishes its guaranty of the Guaranteed Obligations (as hereinafter defined) pursuant to this Continuing Guaranty dated as of July 29, 2009 as follows:

1. GUARANTY. The Guarantor hereby absolutely and unconditionally guarantees, as a guaranty of payment and performance and not merely as a guaranty of collection, prompt payment when due, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of all “Obligations” as defined in the Credit Agreement, and any and all existing and future indebtedness and liabilities of every kind, nature and character, direct or indirect, absolute or contingent, liquidated or unliquidated, voluntary or involuntary and whether for principal, interest, premiums, fees, indemnities, damages, costs, expenses or otherwise, of the Borrower to the Administrative Agent and any other Secured Party arising under the Credit Agreement, any other Loan Documents and any instruments, agreements or other documents of any kind or nature now or hereafter executed in connection therewith (including all renewals, extensions, amendments, refinancings and other modifications thereof and all costs, attorneys’ fees and expenses incurred by the Administrative Agent and any other Secured Party in connection with the collection or enforcement thereof), and whether recovery upon such indebtedness and liabilities may be or hereafter become unenforceable or shall be an allowed or disallowed claim under any proceeding or case commenced by or against any Guarantor or the Borrower under the Bankruptcy Code (Title 11, United States Code), any successor statute or any other liquidation, conservatorship, bankruptcy, assignment for the benefit of creditors, moratorium, rearrangement, receivership, insolvency, reorganization, or similar debtor relief laws of the United States or other applicable jurisdictions from time to time in effect and affecting the rights of creditors generally (collectively, “Debtor Relief Laws”), and including interest that accrues after the commencement by or against the Borrower of any proceeding under any Debtor Relief Laws (collectively, the “Guaranteed Obligations”). The books and records of the Administrative Agent and the books and records of each Secured Party showing the amount of the Guaranteed Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon the Guarantor and conclusive for the purpose of establishing the amount of the Guaranteed Obligations. This Guaranty shall not be affected by the genuineness, validity, regularity or enforceability of the Guaranteed Obligations or any instrument or agreement evidencing any Guaranteed Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent of any collateral therefor, or by any fact or circumstance relating to the Guaranteed Obligations which might otherwise constitute a defense to the obligations of the Guarantor under this Guaranty, and the Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing. Anything contained herein to the contrary notwithstanding, the

obligations of the Guarantor hereunder at any time shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Code (Title 11, United States Code) or any comparable provisions of any similar federal or state law.

2. NO SETOFF OR DEDUCTIONS; TAXES; PAYMENTS. The Guarantor represents and warrants that it is organized and resident in the United States of America. The Guarantor shall make all payments hereunder without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Guarantor is compelled by law to make such deduction or withholding. If any such obligation (other than one arising with respect to taxes based on or measured by the income or profits of the Administrative Agent or any other Secured Party) is imposed upon the Guarantor with respect to any amount payable by it hereunder, the Guarantor will pay to the Administrative Agent or such other Secured Party, on the date on which such amount is due and payable hereunder, such additional amount in Dollars as shall be necessary to enable the Administrative Agent or such other Secured Party to receive the same net amount which the Administrative Agent or such other Secured Party would have received on such due date had no such obligation been imposed upon the Guarantor. The Guarantor will deliver promptly to the Administrative Agent or such other Secured Party certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Guarantor hereunder. Payments by the Guarantor shall be made to the Administrative Agent in accordance with Section 2.11 of the Credit Agreement and shall be credited and applied in accordance with Section 8.03 of the Credit Agreement. The obligations of the Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty.

3. RIGHTS OF ADMINISTRATIVE AGENT AND THE OTHER SECURED PARTIES. The Guarantor consents and agrees that the Administrative Agent and the other Secured Parties may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (a) amend, extend, renew, compromise, discharge, accelerate or otherwise change the time for payment or the terms of the Guaranteed Obligations or any part thereof; (b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this Guaranty or any Guaranteed Obligations; (c) apply such security and direct the order or manner of sale thereof as the Administrative Agent and the other Secured Parties in their sole discretion (subject to the terms of the Loan Documents) may determine; and (d) release or substitute one or more of any endorsers or other guarantors of any of the Guaranteed Obligations. Without limiting the generality of the foregoing, the Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of the Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of the Guarantor.

4. CERTAIN WAIVERS. The Guarantor waives (a) any defense arising by reason of any disability or other defense of the Borrower or any other guarantor, or the cessation from any cause whatsoever (including any act or omission of the Administrative Agent or any other Secured Party) of the liability of the Borrower other than payment in full of the Guaranteed

Obligations; (b) any defense based on any claim that the Guarantor’s obligations exceed or are more burdensome than those of the Borrower; (c) the benefit of any statute of limitations affecting the Guarantor’s liability hereunder; (d) any right to require the Administrative Agent or any other Secured Party to proceed against the Borrower, proceed against or exhaust any security for the Indebtedness, or pursue any other remedy in the Administrative Agent’s or any other Secured Party’s power whatsoever; (e) any benefit of and any right to participate in any security now or hereafter held by the Administrative Agent or any other Secured Party; and (f) to the fullest extent permitted by law, any and all other defenses or benefits that may be derived from or afforded by applicable law limiting the liability of or exonerating guarantors or sureties. The Guarantor expressly waives all setoffs and counterclaims and all presentments, demands for payment or performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Guaranteed Obligations, and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Guaranteed Obligations. In accordance with Section 2856 of the California Civil Code the Guarantor waives any and all rights and defenses available to it by reason of Sections 2787 to 2855, inclusive, 2899 and 3433 of the California Civil Code, including any and all rights or defenses the Guarantor may have because the Obligations are secured by real property or by reason of protection afforded to the Guarantor with respect to any of the Obligations pursuant to the antideficiency or other laws of the State of California limiting or discharging a principal’s indebtedness or a guarantor’s obligations, including Section 580a, 580b, 580d or 726 of the California Code of Civil Procedure. Consequently, among other things: (1) the Secured Parties may collect from the Guarantor without first foreclosing on any real or personal property collateral pledged by the Guarantor; and (2) if the Secured Parties foreclose on any real property collateral pledged by the Guarantor: (x) the amount of the Obligations may be reduced only by the price for which the collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price and (y) the Secured Parties may collect from the Guarantor even if the Secured Parties, by foreclosing on the real property collateral, have destroyed any right the Guarantor may have to collect from the Borrower. This is an unconditional and irrevocable waiver of any rights and defenses the Guarantor may have because the Obligations are secured by real property. The Guarantor also waives all rights and defenses arising out of an election of remedies by the Secured Parties, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for an Obligation, has destroyed the Guarantor’s rights of subrogation and reimbursement against the Borrower by the operation of Section 580d of the California Code of Civil Procedure or otherwise; and even though that election of remedies by the Secured Parties, such as nonjudicial foreclosure with respect to security for an obligation of the Guarantor, has destroyed the Borrower’s rights of contribution against the Guarantor. As provided below, this Guaranty shall be governed by, and construed in accordance with, the laws of the State of New York. The foregoing waivers and the provisions hereinafter set forth in this Guaranty which pertain to California law are included solely out of an abundance of caution, and shall not be construed to mean that any of the above referenced provisions of California law are in any way applicable to this Guaranty or the Guaranteed Obligations.

5. OBLIGATIONS INDEPENDENT. The obligations of the Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of the Guaranteed Obligations and the obligations of any other guarantor, and a separate action may be

brought against the Guarantor to enforce this Guaranty whether or not the Borrower or any other person or entity is joined as a party.

6. SUBROGATION. The Guarantor shall not exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect to any payments it makes under this Guaranty until all of the Guaranteed Obligations and any amounts payable under this Guaranty have been indefeasibly paid and performed in full and any commitments of the Administrative Agent and each other Secured Party or facilities provided by the Administrative Agent and each other Secured Party with respect to the Guaranteed Obligations are terminated. If any amounts are paid to the Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust for the benefit of the Administrative Agent and the other Secured Parties and shall forthwith be paid to the Administrative Agent (for the benefit of itself and the other Secured Parties) to reduce the amount of the Guaranteed Obligations, whether matured or unmatured.

7. CONTRIBUTION. Subject to Paragraph 6 above, the Guarantor hereby agrees with each other Guarantor that if any Guarantor shall make an Excess Payment (as defined below), such Guarantor shall have a right of contribution from each other Guarantor in an amount equal to such other Guarantor’s Contribution Share (as defined below) of such Excess Payment. The payment obligations of any Guarantor under this Paragraph 7 shall be subordinate and subject in right of payment to the Guaranteed Obligations until such time as the Guaranteed Obligations have been paid in full, and no Guarantor shall exercise any right or remedy under this Paragraph 7 against any other Guarantor until such Guaranteed Obligations have been paid in full.

For purposes of this Paragraph 7:

(a) “Excess Payment” shall mean the amount paid by any Guarantor in excess of its Ratable Share of any Guaranteed Obligations;

(b) “Ratable Share” shall mean, for any Guarantor in respect of any payment of Guaranteed Obligations, the ratio (expressed as a percentage) as of the date of such payment of Guaranteed Obligations of (i) the amount by which the aggregate present fair salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Guarantor (including probable contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of such Guarantor hereunder) to (ii) the amount by which the aggregate present fair salable value of all assets and other properties of all of the Guarantors exceeds the amount of all of the debts and liabilities (including probable contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of the Guarantors hereunder) of the Guarantors; provided, however, that, for purposes of calculating the Ratable Shares of the Guarantors in respect of any payment of Guaranteed Obligations, any Guarantor that became a Guarantor subsequent to the date of any such payment shall be deemed to have been a Guarantor on the date of such payment and the financial information for such Guarantor as of the date such Guarantor became a Guarantor shall be utilized for such Guarantor in connection with such payment; and

(c) “Contribution Share” shall mean, for any Guarantor in respect of any Excess Payment made by any other Guarantor, the ratio (expressed as a percentage) as of the date of such Excess Payment of (i) the amount by which the aggregate present fair salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Guarantor (including probable contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of such Guarantor hereunder) to (ii) the amount by which the aggregate present fair salable value of all assets and other properties of the Guarantors other than the maker of such Excess Payment exceeds the amount of all of the debts and liabilities (including probable contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of the Guarantors) of the Guarantors other than the maker of such Excess Payment; provided, however, that, for purposes of calculating the Contribution Shares of the Guarantors in respect of any Excess Payment, any Guarantor that became a Guarantor subsequent to the date of any such Excess Payment shall be deemed to have been a Guarantor on the date of such Excess Payment and the financial information for such Guarantor as of the date such Guarantor became a Guarantor shall be utilized for such Guarantor in connection with such Excess Payment.

Each Guarantor recognizes and acknowledges that the rights to contribution arising hereunder shall constitute an asset in favor of the party entitled to such contribution. This Paragraph 7 shall not be deemed to affect any right of subrogation, indemnity, reimbursement or contribution that any Guarantor may have under applicable Law against the Borrower in respect of any payment of Guaranteed Obligations.

8. TERMINATION; REINSTATEMENT. This Guaranty is a continuing and irrevocable guaranty of all Guaranteed Obligations now or hereafter existing and shall remain in full force and effect until all Guaranteed Obligations and any other amounts payable under this Guaranty are indefeasibly paid in full in cash and any commitments of the Administrative Agent and each other Secured Party or facilities provided by the Administrative Agent and any other Secured Party with respect to the Guaranteed Obligations are terminated. Notwithstanding the foregoing, this Guaranty shall continue in full force and effect or be revived, as the case may be, if any payment by or on behalf of the Borrower or the Guarantor is made, or the Administrative Agent or any other Secured Party exercises its right of setoff, in respect of the Guaranteed Obligations and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or any other Secured Party in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not the Administrative Agent or any other Secured Party is in possession of or has released this Guaranty and regardless of any prior revocation, rescission, termination or reduction. The obligations of the Guarantor under this paragraph shall survive termination of this Guaranty.

9. SUBORDINATION. The Guarantor hereby subordinates the payment of all obligations and indebtedness of the Borrower owing to the Guarantor, whether now existing or hereafter arising, including but not limited to any obligation of the Borrower to the Guarantor as subrogee of the Administrative Agent and any other Secured Party or resulting from the

Guarantor’s performance under this Guaranty, to the indefeasible payment in full in cash of all Guaranteed Obligations. If the Administrative Agent so requests, any such obligation or indebtedness of the Borrower to the Guarantor shall be enforced and performance received by the Guarantor as trustee for the Administrative Agent and the proceeds thereof shall be paid over to the Administrative Agent on account of the Guaranteed Obligations, but without reducing or affecting in any manner the liability of the Guarantor under this Guaranty.

10. STAY OF ACCELERATION. In the event that acceleration of the time for payment of any of the Guaranteed Obligations is stayed, in connection with any case commenced by or against the Borrower or any other Guarantor under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by the Guarantor immediately upon demand by the Administrative Agent.

11. EXPENSES. The Guarantor shall pay on demand all out-of-pocket expenses (including attorneys’ fees and expenses) in any way relating to the enforcement or protection of the Administrative Agent’s and each other Secured Party’s rights under this Guaranty or in respect of the Guaranteed Obligations, including any incurred during any “workout” or restructuring in respect of the Guaranteed Obligations and any incurred in the preservation, protection or enforcement of any rights of the Administrative Agent and each other Secured Party in any proceeding under any Debtor Relief Laws. The obligations of the Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty.

12. MISCELLANEOUS. No provision of this Guaranty may be waived, amended, supplemented or modified, except by a written instrument executed by the Administrative Agent and the Guarantor. No failure by the Administrative Agent or any other Secured Party to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy or power hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies herein provided are cumulative and not exclusive of any remedies provided by law or in equity. The unenforceability or invalidity of any provision of this Guaranty shall not affect the enforceability or validity of any other provision herein. Unless otherwise agreed by the Administrative Agent and the Guarantor in writing, this Guaranty is not intended to supersede or otherwise affect any other guaranty now or hereafter given by the Guarantor for the benefit of the Administrative Agent and the other Secured Parties or any term or provision thereof.

13. CONDITION OF BORROWER. The Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Borrower and any other guarantor such information concerning the financial condition, business and operations of the Borrower and any such other guarantor as the Guarantor requires, and that the Administrative Agent and the other Secured Parties have no duty, and the Guarantor is not relying on the Administrative Agent or any other Secured Party at any time, to disclose to the Guarantor any information relating to the business, operations or financial condition of the Borrower or any other guarantor (the guarantor waiving any duty on the part of the Administrative Agent and the other Secured Parties to disclose such information and any defense relating to the failure to provide the same).

14. SETOFF. If and to the extent any payment is not made when due hereunder, the Guarantor hereby irrevocably authorizes each Secured Party and each of their respective Affiliates at any time and from time to time, after obtaining the prior written consent of the Administrative Agent, to the fullest extent permitted by applicable Laws, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Secured Party or any such Affiliate to or for the credit or the account of the Guarantor against any and all of the obligations of the Guarantor now or hereafter existing under this Agreement or any other Loan Document to such Secured Party, irrespective of whether or not such Secured Party shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Guarantor may be contingent or unmatured or are owed to a branch or office of such Secured Party different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Secured Party and its respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Secured Party or its respective Affiliates may have. Each Secured Party agrees to notify the Guarantor promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

15. REPRESENTATIONS AND WARRANTIES. The Guarantor represents and warrants that (a) it is duly organized and in good standing under the laws of the jurisdiction of its organization and has full capacity and right to make and perform this Guaranty, and all necessary authority has been obtained; (b) this Guaranty constitutes its legal, valid and binding obligation enforceable in accordance with its terms; (c) the making and performance of this Guaranty does not and will not violate the provisions of any applicable law, regulation or order, and does not and will not result in the breach of, or constitute a default or require any consent under, any material agreement, instrument, or document to which it is a party or by which it or any of its property may be bound or affected; and (d) all consents, approvals, licenses and authorizations of, and filings and registrations with, any governmental authority required under applicable law and regulations for the making and performance of this Guaranty have been obtained or made and are in full force and effect.

16. INDEMNIFICATION AND SURVIVAL. Without limitation on any other obligations of the Guarantor or remedies of the Administrative Agent or any other Secured Party under this Guaranty, the Guarantor shall, to the fullest extent permitted by law, indemnify, defend and save and hold harmless the Administrative Agent and each other Secured Party from and against, and shall pay on demand, any and all damages, losses, liabilities and expenses (including attorneys’ fees and expenses) that may be suffered or incurred by the Administrative Agent or any other Secured Party in connection with or as a result of any failure of any Guaranteed Obligations to be the legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms. The obligations of the Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty.

17. GOVERNING LAW; ASSIGNMENT; JURISDICTION; NOTICES. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK. This Guaranty shall

(a) bind the Guarantor and its successors and assigns, provided that the Guarantor may not assign its rights or obligations under this Guaranty without the prior written consent of the Administrative Agent (and any attempted assignment without such consent shall be void), and (b) inure to the benefit of the Administrative Agent and each other Secured Party and their respective successors and assigns and each Secured Party may, without notice to the Guarantor and without affecting the Guarantor’s obligations hereunder, assign, sell or grant participations in the Guaranteed Obligations and this Guaranty, in whole or in part. The Guarantor hereby irrevocably (i) submits to the non-exclusive jurisdiction of any United States Federal or State court sitting in New York, New York in any action or proceeding arising out of or relating to this Guaranty, and (ii) waives to the fullest extent permitted by law any defense asserting an inconvenient forum in connection therewith. Service of process by the Administrative Agent in connection with such action or proceeding shall be binding on the Guarantor if sent to the Guarantor in the manner set forth below. The Guarantor agrees that the Administrative Agent and each other Secured Party may disclose to any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations of all or part of the Guaranteed Obligations any and all information in the Administrative Agent’s or such Secured Party’s possession concerning the Guarantor, this Guaranty and any security for this Guaranty. All notices and other communications to the Guarantor under this Guaranty shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopier to the Guarantor at its address set forth below or at such other address in the United States as may be specified by the Guarantor in a written notice delivered to the Administrative Agent at such office as the Administrative Agent may designate for such purpose from time to time in a written notice to the Guarantor.

18. WAIVER OF JURY TRIAL; FINAL AGREEMENT. TO THE EXTENT ALLOWED BY APPLICABLE LAW, EACH GUARANTOR AND EACH SECURED PARTY HERETO IRREVOCABLY WAIVES TRIAL BY JURY WITH RESPECT TO ANY ACTION, CLAIM, SUIT OR PROCEEDING ON, ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE GUARANTEED OBLIGATIONS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. THIS GUARANTY REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

19. ADDITIONAL GUARANTOR WAIVERS AND AGREEMENTS.

(a) The Guarantor understands and acknowledges that if the Administrative Agent or any other Secured Party forecloses judicially or nonjudicially against any real property security for the Guaranteed Obligations, that foreclosure could impair or destroy any ability that the Guarantor may have to seek reimbursement, contribution, or indemnification from the

Borrower or others based on any right the Guarantor may have of subrogation, reimbursement, contribution, or indemnification for any amounts paid by the Guarantor under this Guaranty. The Guarantor further understands and acknowledges that in the absence of this paragraph, such potential impairment or destruction of the Guarantor’s rights, if any, may entitle the Guarantor to assert a defense to this Guaranty based on Section 580d of the California Code of Civil Procedure as interpreted in Union Bank v. Gradsky, 265 Cal.App.2d 40 (1968). By executing this Guaranty, the Guarantor freely, irrevocably, and unconditionally: (i) waives and relinquishes that defense and agrees that the Guarantor will be fully liable under this Guaranty even though the Administrative Agent or any other Secured Party may foreclose, either by judicial foreclosure or by exercise of power of sale, any deed of trust securing the Guaranteed Obligations; (ii) agrees that the Guarantor will not assert that defense in any action or proceeding which the Administrative Agent or any other Secured Party may commence to enforce this Guaranty; (iii) acknowledges and agrees that the rights and defenses waived by the Guarantor in this Guaranty include any right or defense that the Guarantor may have had or be entitled to assert based on or arising out of any one or more of Sections 580a, 580b, 580d, or 726 of the California Code of Civil Procedure or Section 2848 of the California Civil Code; and (iv) acknowledges and agrees that the Administrative Agent and each other Secured Party is relying on this waiver in creating the Guaranteed Obligations, and that this waiver is a material part of the consideration which the Administrative Agent and each other Secured Party is receiving for creating the Guaranteed Obligations.

(b) The Guarantor waives all rights and defenses that the Guarantor may have because any of the Guaranteed Obligations is secured by real property. This means, among other things: (i) The Administrative Agent and each other Secured Party may collect from the Guarantor without first foreclosing on any real or personal property collateral pledged by the Borrower; and (ii) if the Administrative Agent or any other Secured Party forecloses on any real property collateral pledged by the Borrower or any other Person: (A) the amount of the Guaranteed Obligations may be reduced only by the price for which the collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price, and (B) the Administrative Agent or any other Secured Party may collect from the Guarantor even if the Administrative Agent or any other Secured Party, by foreclosing on the real property collateral, has destroyed any right the Guarantor may have to collect from the Borrower or any other Person. This is an unconditional and irrevocable waiver of any rights and defenses the Guarantor may have because any of the Guaranteed Obligations is secured by real property. These rights and defenses include, but are not limited to, any right or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code of Civil Procedure.

(c) The Guarantor waives any right or defense it may have at law or equity, including California Code of Civil Procedure Section 580a, to a fair market value hearing or action to determine a deficiency judgment after a foreclosure.
