This Purchase Agreement shall be governed by the laws of the State of California. 12. Establishment of Issue Price. (a) The Underwriter agrees to assist the City in establishing the issue price of the Bonds and shall execute and deliver to the City at Closing an “issue price” or similar certificate, together with the supporting pricing wires or equivalent communications, substantially in the form attached hereto as Exhibit D, with such modifications as may be appropriate or necessary, in the reasonable judgment of the Underwriter, the City and Bond Counsel, to accurately reflect, as applicable, the sales price or prices or the initial offering price or prices to the public of the Bonds. All actions to be taken by the City under this section to establish the issue price of the Bonds may be taken on behalf of the City by the Municipal Advisor, identified herein and any notice or report to be provided to the City may be provided to the Municipal Advisor. (b) Except as otherwise set forth in Exhibit A, the City will treat the first price at which 10% of each maturity of the Bonds (the “10% test”) is sold to the public as the issue price of that maturity (if different interest rates apply within a maturity, each separate CUSIP number within that maturity will be subject to the 10% test). At or promptly after the execution of this Purchase Agreement, the Underwriter shall report to the City the price or prices at which it has sold to the public each maturity of Bonds. If at that time the 10% test has not been satisfied as to any maturity of the Bonds, the Underwriter agrees to promptly report to the City the prices at which it sells the unsold Bonds of that maturity to the public. That reporting obligation shall continue, whether or not the Closing Date has occurred, until the 10% test has been satisfied as to the Bonds of that maturity or until all Bonds of that maturity have been sold to the public. 16 4913-3020-7144/200356-0701
(c) The Underwriter confirms that it has offered the Bonds to the public on or before the date of this Purchase Agreement at the offering price or prices (the “initial offering price”), or at the corresponding yield or yields, set forth in Exhibit A, except as otherwise set forth therein. Exhibit A also sets forth, identified under the column “Hold-the-Offering-Price Rule Used,” as of the date of this Purchase Agreement, the maturities, if any, of the Bonds for which the 10% test has not been satisfied and for which the City and the Underwriter agree that the restrictions set forth in the next sentence shall apply, which will allow the City to treat the initial offering price to the public of each such maturity as of the sale date as the issue price of that maturity (the “hold-the-offering-price rule”). So long as the hold-the-offering-price rule remains applicable to any maturity of the Bonds, the Underwriter will neither offer nor sell unsold Bonds of that maturity to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following: (1) the close of the fifth (5th) business day after the sale date; or (2) the date on which the Underwriter has sold at least 10% of that maturity of the Bonds to the public at a price that is no higher than the initial offering price to the public. The Underwriter shall promptly advise the City when it has sold 10% of that maturity of the Bonds to the public at a price that is no higher than the initial offering price to the public, if that occurs prior to the close of the fifth (5th) business day after the sale date. (d) The Underwriter confirms that any selling group agreement and any retail distribution agreement relating to the initial sale of the Bonds to the public, together with the related pricing wires, contains or will contain language obligating each dealer who is a member of the selling group and each broker-dealer that is a party to such retail distribution agreement, as applicable, to: (1) report the prices at which it sells to the public the unsold Bonds of each maturity allotted to it until it is notified by the Underwriter that either the 10% test has been satisfied as to the Bonds of that maturity or all Bonds of that maturity have been sold to the public; and (2) comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the Underwriter. The City acknowledges that, in making the representation set forth in this subsection, the Underwriter will rely on: (A) in the event that a selling group has been created in connection with the initial sale of the Bonds to the public, the agreement of each dealer who is a member of the selling group to comply with the hold-the-offering-price rule, if applicable, as set forth in a selling group agreement and the related pricing wires; and (B) in the event that a retail distribution agreement was employed in connection with the initial sale of the Bonds to the public, the agreement of each broker-dealer that is a party to such agreement to comply with the hold-the-offering-price rule, if applicable, as set forth in the retail distribution agreement and the related pricing wires. The City further acknowledges that the Underwriter shall not be liable for the failure of any dealer who is a member of a selling group, or of any broker-dealer that is a party to a retail distribution agreement, to comply with its corresponding agreement regarding the hold-the-offering-price rule as applicable to the Bonds. (e) The Underwriter acknowledges that sales of any Bonds to any person that is a related party to the Underwriter shall not constitute sales to the public for purposes of this section. Further, for purposes of this section: (1) “public” means any person other than an underwriter or a related party; 17 4913-3020-7144/200356-0701
(2) “underwriter” means: (A) any person that agrees pursuant to a written contract with the City (or with the lead underwriter to form an underwriting syndicate) to participate in the initial sale of the Bonds to the public; and (B) any person that agrees pursuant to a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the Bonds to the public (including a member of a selling group or a party to a retail distribution agreement participating in the initial sale of the Bonds to the public); (3) a purchaser of any of the Bonds is a “related party” to an underwriter if the underwriter and the purchaser are subject, directly or indirectly, to: (A) at least 50% common ownership of the voting power or the total value of their stock, if both entities are corporations (including direct ownership by one corporation of another); (ii) more than 50% common ownership of their capital interests or profits interests, if both entities are partnerships (including direct ownership by one partnership of another); or (iii) more than 50% common ownership of the value of the outstanding stock of the corporation or the capital interests or profit interests of the partnership, as applicable, if one entity is a corporation and the other entity is a partnership (including direct ownership of the applicable stock or interests by one entity of the other); and (4) “sale date” means the date of execution of this Purchase Agreement by all parties.

The undersigned has not conducted any extraordinary inspection or inquiry other than such inspections or inquiries as are prudent and customary in connection with the ordinary course of the Master Developer’s current business and operations. Individuals who are no longer employees of the Master Developer and its Affiliates have not been contacted. 2 “Affiliate” means, with respect to the Master Developer, any other Person: (i) who directly, or indirectly through one or more intermediaries, is currently controlling, controlled by or under common control with the Master Developer; and (ii) for whom information, including financial information or operating data, concerning such Person is material to potential investors in their evaluation of the Improvement Area and an investment decision regarding the Bonds (i.e., information relevant to: (a) the Master Developer’s development plans with respect to the Property and ability to pay its Special Taxes on the Property prior to delinquency (to the extent the responsibility of the Master Developer); or (b) such Person’s assets or funds that would materially affect the Master Developer’s ability to develop the Property as described in the Preliminary Official Statement or to pay its Special Taxes on the Property prior to delinquency (to the extent the responsibility of the Master Developer); or (c) such Person’s compliance with continuing disclosure undertakings that would materially affect the Master Developer’s ability to comply with its obligations under the Master Developer Continuing Disclosure Certificate). “Person” means an individual, a corporation, a partnership, a limited liability company, an association, a joint stock company, a trust, any unincorporated organization or a government or political subdivision thereof. For purposes hereof, the term “control” (including the terms “controlling,” “controlled by” or “under common control with”) means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of voting securities, by contract or otherwise.

Except as disclosed in the Preliminary Official Statement, there are no material loans that are outstanding and unpaid, and no material lines of credit of the Master Developer or its Affiliates, which are secured by an interest in the Property. Except as disclosed in the Preliminary Official Statement, to the Actual Knowledge of the Undersigned, the Master Developer and its Affiliates are not in breach of or in default under any applicable judgment or decree or any loan agreement, option agreement, development agreement, indenture, fiscal agent agreement, bond or note to which the Master Developer or its Affiliates are a party or otherwise subject, which breach or default could reasonably be expected to materially and adversely affect the Master Developer’s ability to develop the Property as described in the Preliminary Official Statement or to pay the Special Taxes due with respect to the Property prior to delinquency (to the extent the responsibility of the Master Developer). 7. To the Actual Knowledge of the Undersigned, the Master Developer is not aware that any of the Property has a current liability with respect to the presence of a substance that is presently classified as hazardous under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 or applicable State law or is adversely affected by the presence of endangered or threatened species or habitat for endangered or threatened species. 8. The Master Developer covenants that, while the Bonds or any refunding obligations related thereto are outstanding, the Master Developer and its Affiliates which it controls will not bring any action, suit, proceeding, inquiry or investigation at law or in equity, before any court, regulatory agency, public board or body, that in any way seeks to challenge or overturn the formation of the Community Facilities District or the designation of the Improvement Area, to challenge the adoption of the District Resolutions, to invalidate the Community Facilities District or the Improvement Area or any of the Bonds or any refunding bonds related thereto, or to invalidate the Special Tax liens imposed under the Law based on recordation of the notices of Special Tax lien relating thereto. The foregoing covenant shall not prevent the Master Developer or any Affiliate in any way from bringing any other action, suit, proceeding, inquiry or investigation at law or in equity, before any court, regulatory agency, public board or body including, without limitation: (a) an action

C-1-4 4913-3020-7144/200356-0701
or suit contending that the Special Tax has not been levied in accordance with the methodologies that are contained in the Amended Rate and Method (as such term is defined in the Fiscal Agent Agreement) pursuant to which the Special Taxes are levied; (b) an action or suit with respect to the application or use of the Special Taxes levied and collected; or (c) an action or suit to enforce the obligations of the City and/or the Community Facilities District under the District Resolutions, the Fiscal Agent Agreement or any other agreements among the Master Developer or an Affiliate, the City and/or the Community Facilities District or to which the Master Developer or an Affiliate is a beneficiary or a party. 9. The Master Developer consents to the issuance of the Bonds. The Master Developer acknowledges and agrees that the proceeds of the Bonds will be used as described in the Preliminary Official Statement. 10. The Master Developer intends to comply with the provision of the Law relating to the Notice of Special Tax described in California Government Code Section 53341.5 in connection with the sale of the Property, or portions thereof. 11. To the Actual Knowledge of the Undersigned, the Master Developer is able to pay its bills as they become due and no legal proceedings are pending against the Master Developer (with proper service of process having been accomplished) or, to the Actual Knowledge of the Undersigned, threatened in writing in which the Master Developer may be adjudicated as bankrupt or discharged from any and all of its debts or obligations, or granted an extension of time to pay its debts or obligations, or be allowed to reorganize or readjust its debts, or be subject to control or supervision of the Federal Deposit Insurance Corporation. 12. To the Actual Knowledge of the Undersigned, Affiliates of the Master Developer are able to pay their bills as they become due and no legal proceedings are pending against any Affiliate of the Master Developer (with proper service of process having been accomplished) or to the Actual Knowledge of the Undersigned, threatened in writing in which the Affiliates of the Master Developer may be adjudicated as bankrupt or discharged from any or all of their debts or obligations, or granted an extension of time to pay their debt or obligations, or be allowed to reorganize or readjust their debts or obligations, or be subject to control or supervision of the Federal Deposit Insurance Corporation. 13. To the Actual Knowledge of the Undersigned, during the last five years, neither the Master Developer nor any Affiliate has, during the period of its ownership, been delinquent to any material extent in the payment of any ad valorem property tax, special assessment or special tax on property that is within the boundaries of a community facilities district or an assessment district in the State that: (a) caused a draw on a reserve fund relating to such assessment district or community facilities district financing; or (b) resulted in a foreclosure action being commenced in a court of law against the delinquent Master Developer or Affiliate. 14. The Master Developer has not filed for the reassessment of the assessed value of portions of the Property. 15. To the Actual Knowledge of the Undersigned, there are no claims, disputes, suits, actions or contingent liabilities by and among the Master Developer, its Affiliates or any contractors working on the development of the Property which are reasonably likely to materially and adversely affect the development of the Property as described in the Preliminary Official Statement or the

C-1-5 4913-3020-7144/200356-0701
payment of the Special Taxes that are due with respect to the Property prior to delinquency (to the extent the responsibility of the Master Developer). 16. Based upon the Master Developer’s current development plans for the Property, including, without limitation, the current budget, and subject to economic conditions and risks that are generally inherent in the development of real property, including, but not limited to, the risks that are described in the Preliminary Official Statement under the captions “PROPERTY OWNERSHIP AND DEVELOPMENT STATUS” and “BOND OWNERS’ RISKS,” the Master Developer presently anticipates that it will have sufficient funds to develop the Property as described in the Preliminary Official Statement and to pay Special Taxes levied against the Property prior to delinquency (to the extent the responsibility of the Master Developer). The Master Developer does not anticipate that the City will be required to resort to a draw on the 2024 Reserve Fund for payment of principal of or interest on the Bonds due to the Master Developer’s nonpayment of Special Taxes. However, neither the Master Developer nor any of its Affiliates are obligated to make any additional capital contribution or loan to the Master Developer at any time, and the Master Developer reserves the right to change its development plan and financing plan for the Property at any time without notice. 17. Solely as to the limited information that is described in Paragraph 5 above concerning the Master Developer, its Affiliates, the proposed development of the Property, ownership of the Property, the Master Developer’s development plan, the Master Developer’s financing plan, the Master Developer’s lenders, if any, and contract arrangements of the Master Developer and its Affiliates (including, if material to the Master Developer’s development plan or the Master Developer’s financing plan, other loans of such Affiliates), the Master Developer agrees to indemnify and hold harmless, to the extent permitted by law, the City and the Community Facilities District, and their officials and employees, and each Person, if any, who controls any of the foregoing within the meaning of Section 15 of the Securities Act of 1933, as amended, or of Section 20 of the Securities Exchange Act of 1934, as amended (each, an “Indemnified Party” and, collectively, the “Indemnified Parties”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject under any statute or at law or in equity and shall reimburse any such Indemnified Party for any actual reasonable legal or other expense incurred by it in connection with investigating any such claim against it and defending any such action, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement by the Master Developer of a material fact or the omission of a material fact by the Master Developer in the above-referenced information in the Preliminary Official Statement, as of its date, or in any annual or semi-annual report or notice of significant event provided by the Master Developer pursuant to the Master Developer Continuing Disclosure Certificate, as of its date, that is necessary to make the statements made by the Master Developer contained therein, in light of the circumstances under which they were made, not misleading. This indemnity provision shall not be construed as a limitation on any other liability which the Master Developer may otherwise have to any Indemnified Party, provided that in no event shall the Master Developer be obligated for double indemnification, or for the negligence or willful misconduct of an Indemnified Party. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Indemnified Party in respect of which indemnification is believed by the Indemnified Party to be owed pursuant to the above paragraph, such Indemnified Party shall promptly notify the Master Developer in writing; provided that the failure to notify the Master Developer shall not relieve it from any liability that it may have hereunder except to the extent that it has been materially prejudiced by such failure, and then only to

C-1-6 4913-3020-7144/200356-0701
the extent of such material prejudice. If any such proceeding shall be brought or asserted against an Indemnified Party and it shall have notified the Master Developer thereof, the Master Developer shall retain counsel that is reasonably satisfactory to the Indemnified Party (who may be counsel to the Master Developer) to represent the Indemnified Party in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless: (i) the Master Developer and the Indemnified Party shall have mutually agreed to the contrary; (ii) the Master Developer has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Party; (iii) the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Master Developer such that a material conflict of interest exists for such counsel; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Master Developer and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them under applicable law, rule or regulation determined by the appointed counsel in his or her professional opinion. It is understood and agreed that the Master Developer shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Parties, and that all such fees and expenses, to the extent reasonable, shall be paid or reimbursed as they are incurred. Any such separate firm shall be designated in writing by such Indemnified Parties. The Master Developer shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Master Developer agrees to indemnify each Indemnified Party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested that the Master Developer reimburse the Indemnified Party for fees and expenses of counsel as contemplated by this paragraph, the Master Developer shall be liable for any settlement of any proceeding effected without its written consent if: (1) such settlement is entered into more than 60 days after receipt by the Master Developer of such request; and (2) the Master Developer shall not have reimbursed the Indemnified Party in accordance with such request prior to the date of such settlement (provided that the foregoing shall not be applicable to any failure to reimburse if the Master Developer is disputing such payment in good faith and shall have paid any amounts which are not in dispute). The Master Developer shall not, without the written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and to the extent that indemnification could have been sought hereunder by such Indemnified Party, unless such settlement: (x) includes an unconditional release of such Indemnified Party, in form and substance reasonably satisfactory to such Indemnified Party, from all liability on claims that are the subject matter of such proceeding and as to which the Master Developer has an obligation to indemnify such Indemnified Party; and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party. 18. The Master Developer agrees to execute a Master Developer Continuing Disclosure Certificate at the time of issuance of the Bonds in substantially the form included in Appendix F to the Preliminary Official Statement. 19. If between the date hereof and the Closing Date any event relating to or affecting the Master Developer, its Affiliates, the proposed development of the Property, ownership of the

C-1-7 4913-3020-7144/200356-0701
Property, the Master Developer’s development plan, the Master Developer’s financing plan, the Master Developer’s lenders, if any, and contractual arrangements of the Master Developer or any Affiliates (including, if material to the Master Developer’s development plan or the Master Developer’s financing plan, other loans of such Affiliates) shall occur of which the Master Developer has actual knowledge which would cause the information under the captions of the Preliminary Official Statement that are described in Paragraph 5 hereof (and subject to the limitations and exclusions contained in Paragraph 5) to contain an untrue statement of a material fact or to omit to state a material fact that is necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Master Developer shall notify the City and the Underwriter. If in the reasonable opinion of counsel to the City or the Underwriter such event requires the preparation and publication of a supplement or amendment to the Preliminary Official Statement, the Master Developer shall reasonably cooperate with the City in the preparation of an amendment or supplement to the Preliminary Official Statement in form and substance that is reasonably satisfactory to counsel to the City and to the Underwriter. 20. The Master Developer agrees to deliver a Closing Certificate dated the date of issuance of the Bonds at the time of issuance of the Bonds in substantially the form attached as Appendix 1. 21. An appraisal of the taxable properties within the Improvement Area (the “Appraisal Report”) was prepared by BBG, Inc. (the “Appraiser”). The Appraisal Report estimates the market value of the taxable properties within the Improvement Area as of June 1, 2026 (the “Date of Value”). To the Actual Knowledge of the Undersigned, taken in its entirety, all information that was submitted by, or on behalf of and authorized by, the Master Developer to the Appraiser and contained in the sections of the Appraisal Report highlighted in yellow in Appendix 2 attached hereto was true and correct in all material respects as of the Date of Value. 22. On behalf of the Master Developer, I have reviewed the contents of this Letter of Representations and have met with counsel to the Master Developer for the purpose of discussing the meaning of the contents of this Letter of Representations. The Master Developer acknowledges and understands that a variety of state and federal securities laws, including, but not limited to the Securities Act of 1933, as amended, and Rule 10b-5 promulgated under the Securities Exchange Act of 1934, as amended, may apply to the Master Developer and that under some circumstances, certification as to the matters set forth in this Letter of Representations, without additional disclosures or other action, may not fully discharge all duties and obligations of the Master Developer under such securities laws. The undersigned has executed this Letter of Representations solely in the undersigned’s capacity as an officer or representative of the Master Developer and the undersigned will have no personal liability arising from or relating to this Letter of Representations. Any liability that arises from or relates to this Letter of Representations may only be asserted against the Master Developer.

Separate and apart from Lennar Corporation’s due diligence efforts for purposes of completing the acquisition of CalAtlantic, for purposes of this Letter of Representations, individuals who were employees and officers of CalAtlantic and its subsidiaries prior to the merger have not been consulted or contacted and documents entered into by CalAtlantic and its subsidiaries or related to their properties and projects have not been reviewed.] [Lennar only] 2 “Affiliate” means, with respect to the Merchant Builder, any other Person: (i) who directly, or indirectly through one or more intermediaries, is currently controlling, controlled by or under common control with the Merchant Builder; and (ii) for whom information, including financial information or operating data, concerning such Person is material to potential investors in their evaluation of the Improvement Area and an investment decision regarding the Bonds (i.e., information relevant to: (a) the Merchant Builder’s development plans with respect to the Property and ability to pay its Special Taxes on the Property prior to delinquency (to the extent the responsibility of the Merchant Builder); or (b) such

Except as disclosed in the Preliminary Official Statement, there are no material loans that are outstanding and unpaid, and no material lines of credit of the Merchant Builder or its Affiliates, which are secured by an interest in the Property. Except as disclosed in the Preliminary Official Statement, to the Actual Knowledge of the Undersigned, the Merchant Builder and its Affiliates are not in breach of or in default under any applicable judgment or decree or any loan agreement, option agreement, development agreement, indenture, fiscal agent agreement, bond or note to which the Merchant Builder or its Affiliates are a party or otherwise subject, which breach or default could reasonably be expected to materially and adversely affect the Merchant Builder’s ability to develop the Property as described in the Preliminary Official Statement or to pay the Special Taxes due with respect to the Property prior to delinquency (to the extent the responsibility of the Merchant Builder). Person’s assets or funds that would materially affect the Merchant Builder’s ability to develop the Property as described in the Preliminary Official Statement or to pay its Special Taxes on the Property prior to delinquency (to the extent the responsibility of the Merchant Builder); or (c) such Person’s compliance with continuing disclosure undertakings that would materially affect the Merchant Builder’s ability to comply with its obligations under the Merchant Builder Continuing Disclosure Certificate). “Person” means an individual, a corporation, a partnership, a limited liability company, an association, a joint stock company, a trust, any unincorporated organization or a government or political subdivision thereof.

7. To the Actual Knowledge of the Undersigned, the Merchant Builder is not aware that any of the Property has a current liability with respect to the presence of a substance that is presently classified as hazardous under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 or applicable State law or is adversely affected by the presence of endangered or threatened species or habitat for endangered or threatened species. 8. The Merchant Builder covenants that, while the Bonds or any refunding obligations related thereto are outstanding, the Merchant Builder and its Affiliates which it controls will not bring any action, suit, proceeding, inquiry or investigation at law or in equity, before any court, regulatory agency, public board or body, that in any way seeks to challenge or overturn the formation of the Community Facilities District or the designation of the Improvement Area, to challenge the adoption of the District Resolutions, to invalidate the Community Facilities District or the Improvement Area or any of the Bonds or any refunding bonds related thereto, or to invalidate the Special Tax liens imposed under the Law based on recordation of the notices of Special Tax lien relating thereto. The foregoing covenant shall not prevent the Merchant Builder or any Affiliate in any way from bringing any other action, suit, proceeding, inquiry or investigation at law or in equity, before any court, regulatory agency, public board or body including, without limitation: (a) an action or suit contending that the Special Tax has not been levied in accordance with the methodologies that are contained in the Amended Rate and Method (as such term is defined in the Fiscal Agent Agreement) pursuant to which the Special Taxes are levied; (b) an action or suit with respect to the application or use of the Special Taxes levied and collected; or (c) an action or suit to enforce the obligations of the City and/or the Community Facilities District under the District Resolutions, the Fiscal Agent Agreement or any other agreements among the Merchant Builder or an Affiliate, the City and/or the Community Facilities District or to which the Merchant Builder or an Affiliate is a beneficiary or a party. 9. The Merchant Builder consents to the issuance of the Bonds. The Merchant Builder acknowledges and agrees that the proceeds of the Bonds will be used as described in the Preliminary Official Statement. 10. The Merchant Builder intends to comply with the provision of the Law relating to the Notice of Special Tax described in California Government Code Section 53341.5 in connection with the sale of the Property, or portions thereof. 11. To the Actual Knowledge of the Undersigned, the Merchant Builder is able to pay its bills as they become due and no legal proceedings are pending against the Merchant Builder (with proper service of process having been accomplished) or, to the Actual Knowledge of the Undersigned, threatened in writing in which the Merchant Builder may be adjudicated as bankrupt or discharged from any and all of its debts or obligations, or granted an extension of time to pay its debts or obligations, or be allowed to reorganize or readjust its debts, or be subject to control or supervision of the Federal Deposit Insurance Corporation. 12. To the Actual Knowledge of the Undersigned, during the last five years, neither the Merchant Builder nor any Affiliate has, during the period of its ownership, been delinquent to any material extent in the payment of any ad valorem property tax, special assessment or special tax on property that is within the boundaries of a community facilities district or an assessment district in the State that: (a) caused a draw on a reserve fund relating to such assessment district or community facilities district financing; or (b) resulted in a foreclosure action being commenced in a court of law against the delinquent Merchant Builder or Affiliate.

13. Based upon the Merchant Builder’s current development plans for the Property, including, without limitation, the current budget, and subject to economic conditions and risks that are generally inherent in the development of real property, including, but not limited to, the risks that are described in the Preliminary Official Statement under the captions “PROPERTY OWNERSHIP AND DEVELOPMENT STATUS” and “BOND OWNERS’ RISKS,” the Merchant Builder presently anticipates that it will have sufficient funds to complete the development of the Property as described in the Preliminary Official Statement and to pay Special Taxes levied against the Property prior to delinquency (to the extent the responsibility of the Merchant Builder). The Merchant Builder does not anticipate that the City will be required to resort to a draw on the 2024 Reserve Fund for payment of principal of or interest on the Bonds due to the Merchant Builder’s nonpayment of Special Taxes. However, neither the Merchant Builder nor any of its Affiliates are obligated to make any additional capital contribution or loan to the Merchant Builder at any time, and the Merchant Builder reserves the right to change its development plan and financing plan for the Property at any time without notice. 14. Solely as to the limited information that is described in Paragraph 5 above concerning the Merchant Builder, its Affiliates, the proposed development of the Property, ownership of the Property, the Merchant Builder’s development plan, the Merchant Builder’s financing plan, the Merchant Builder’s lenders, if any, and contract arrangements of the Merchant Builder and its Affiliates (including, if material to the Merchant Builder’s development plan or the Merchant Builder’s financing plan, other loans of such Affiliates), the Merchant Builder agrees to indemnify and hold harmless, to the extent permitted by law, the City and the Community Facilities District, and their officials and employees, and each Person, if any, who controls any of the foregoing within the meaning of Section 15 of the Securities Act of 1933, as amended, or of Section 20 of the Securities Exchange Act of 1934, as amended (each, an “Indemnified Party” and, collectively, the “Indemnified Parties”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject under any statute or at law or in equity and shall reimburse any such Indemnified Party for any actual reasonable legal or other expense incurred by it in connection with investigating any such claim against it and defending any such action, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement by the Merchant Builder of a material fact or the omission of a material fact by the Merchant Builder in the above-referenced information in the Preliminary Official Statement, as of its date, [or in any annual or semi-annual report or notice of significant event provided by the Merchant Builder pursuant to the Merchant Builder Continuing Disclosure Certificate, as of its date,][Applicable Builders Only] that is necessary to make the statements made by the Merchant Builder contained therein, in light of the circumstances under which they were made, not misleading. This indemnity provision shall not be construed as a limitation on any other liability which the Merchant Builder may otherwise have to any Indemnified Party, provided that in no event shall the Merchant Builder be obligated for double indemnification, or for the negligence or willful misconduct of an Indemnified Party. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Indemnified Party in respect of which indemnification is believed by the Indemnified Party to be owed pursuant to the above paragraph, such Indemnified Party shall promptly notify the Merchant Builder in writing; provided that the failure to notify the Merchant Builder shall not relieve it from any liability that it may have hereunder except to the extent that it has been materially prejudiced by such failure, and then only to the extent of such material prejudice. If any such proceeding shall be brought or asserted against an Indemnified Party and it shall have notified the Merchant Builder thereof, the Merchant Builder shall

C-2-6 4913-3020-7144/200356-0701
retain counsel that is reasonably satisfactory to the Indemnified Party (who may be counsel to the Merchant Builder) to represent the Indemnified Party in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless: (i) the Merchant Builder and the Indemnified Party shall have mutually agreed to the contrary; (ii) the Merchant Builder has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Party; (iii) the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Merchant Builder such that a material conflict of interest exists for such counsel; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Merchant Builder and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them under applicable law, rule or regulation determined by the appointed counsel in his or her professional opinion. It is understood and agreed that the Merchant Builder shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Parties, and that all such fees and expenses, to the extent reasonable, shall be paid or reimbursed as they are incurred. Any such separate firm shall be designated in writing by such Indemnified Parties. The Merchant Builder shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Merchant Builder agrees to indemnify each Indemnified Party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested that the Merchant Builder reimburse the Indemnified Party for fees and expenses of counsel as contemplated by this paragraph, the Merchant Builder shall be liable for any settlement of any proceeding effected without its written consent if: (1) such settlement is entered into more than 60 days after receipt by the Merchant Builder of such request; and (2) the Merchant Builder shall not have reimbursed the Indemnified Party in accordance with such request prior to the date of such settlement (provided that the foregoing shall not be applicable to any failure to reimburse if the Merchant Builder is disputing such payment in good faith and shall have paid any amounts which are not in dispute). The Merchant Builder shall not, without the written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and to the extent that indemnification could have been sought hereunder by such Indemnified Party, unless such settlement: (x) includes an unconditional release of such Indemnified Party, in form and substance reasonably satisfactory to such Indemnified Party, from all liability on claims that are the subject matter of such proceeding and as to which the Merchant Builder has an obligation to indemnify such Indemnified Party; and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party. 15. [The Merchant Builder agrees to execute the Merchant Builder Continuing Disclosure Certificate at the time of issuance of the Bonds in substantially the form included in Appendix G to the Preliminary Official Statement.][Applicable Builders Only] 16. If between the date hereof and the Closing Date any event relating to or affecting the Merchant Builder, its Affiliates, the proposed development of the Property, ownership of the Property, the Merchant Builder’s development plan, the Merchant Builder’s financing plan, the Merchant Builder’s lenders, if any, and contractual arrangements of the Merchant Builder or any

Affiliates (including, if material to the Merchant Builder’s development plan or the Merchant Builder’s financing plan, other loans of such Affiliates) shall occur of which the Merchant Builder has actual knowledge which would cause the information under the captions of the Preliminary Official Statement that are described in Paragraph 5 hereof (and subject to the limitations and exclusions contained in Paragraph 5) to contain an untrue statement of a material fact or to omit to state a material fact that is necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Merchant Builder shall notify the City and the Underwriter. If in the reasonable opinion of counsel to the City or the Underwriter such event requires the preparation and publication of a supplement or amendment to the Preliminary Official Statement, the Merchant Builder shall reasonably cooperate with the City in the preparation of an amendment or supplement to the Preliminary Official Statement in form and substance that is reasonably satisfactory to counsel to the City and to the Underwriter. 17. The Merchant Builder agrees to deliver a Closing Certificate dated the date of issuance of the Bonds at the time of issuance of the Bonds in substantially the form attached as Appendix 1. 18. An appraisal of the taxable properties within the Improvement Area (the “Appraisal Report”) was prepared by BBG, Inc. (the “Appraiser”). The Appraisal Report estimates the market value of the taxable properties within the Improvement Area as of June 1, 2026 (the “Date of Value”). To the Actual Knowledge of the Undersigned, taken in its entirety, all information that was submitted by, or on behalf of and authorized by, the Merchant Builder to the Appraiser and contained in the sections of the Appraisal Report highlighted in yellow in Appendix 2 attached hereto was true and correct in all material respects as of the Date of Value. 19. On behalf of the Merchant Builder, I have reviewed the contents of this Letter of Representations and have met with counsel to the Merchant Builder for the purpose of discussing the meaning of the contents of this Letter of Representations. The Merchant Builder acknowledges and understands that a variety of state and federal securities laws, including, but not limited to the Securities Act of 1933, as amended, and Rule 10b-5 promulgated under the Securities Exchange Act of 1934, as amended, may apply to the Merchant Builder and that under some circumstances, certification as to the matters set forth in this Letter of Representations, without additional disclosures or other action, may not fully discharge all duties and obligations of the Merchant Builder under such securities laws. The undersigned has executed this Letter of Representations solely in the undersigned’s capacity as an officer or representative of the Merchant Builder and the undersigned will have no personal liability arising from or relating to this Letter of Representations. Any liability that arises from or relates to this Letter of Representations may only be asserted against the Merchant Builder. [Merchant Builder Full Name] By: Name: Title:
