See Annex A-1 to this free writing prospectus for specific criteria applicable to the mortgage loans.

Certain mortgage loans may permit the application of escrows to prepay a portion of the principal balance. The application of such escrows may or may not require a payment of a yield maintenance charge or a prepayment premium based on the amount of the principal that is being paid and may be applied during a lockout/defeasance period.

J.P. Morgan Chase Commercial Mortgage Securities Corp. is offering certain classes of the Commercial Mortgage Pass-Through Certificates, Series 2013-C14 consisting of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class X-B, Class A-S, Class B and Class C certificates. The certificates (which are comprised of the certificates offered by this free writing prospectus and the Class X-C, Class D, Class E, Class F, Class G, Class NR and Class R certificates) represent the beneficial ownership interests in the issuing entity, which will be a trust named JPMBB Commercial Mortgage Securities Trust 2013-C14. The assets of the trust will primarily consist of a pool of fixed rate commercial mortgage loans, which are generally the sole source of payments on the certificates. Credit enhancement will be provided solely by certain classes of subordinate certificates that will be subordinate to certain classes of senior certificates as described under “Description of the Certificates—Subordination; Allocation of Collateral Support Deficit” in this free writing prospectus. Each class of certificates will be entitled to receive monthly distributions of interest and/or principal on the 4th business day following the 11th day of each month (or if the 11th is not a business day, the next business day), commencing in September 2013.

Any representation to the contrary is a criminal offense. J.P.

	(1)	Approximate, subject to a permitted variance of plus or minus 5%.

	(2)	The initial credit support percentages set forth for the certificates are approximate and, for the Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates, are represented in the aggregate.

	(3)	The assumed final distribution dates set forth in this free writing prospectus have been determined on the basis of the assumptions described in “Description of the Certificates—Assumed Final Distribution Date; Rated Final Distribution Date” in this free writing prospectus. The rated final distribution date for each class of offered certificates is the distribution date in August 2046. See “Description of the Certificates—Assumed Final Distribution Date; Rated Final Distribution Date” in this free writing prospectus.

	(4)	The weighted average life and period during which distributions of principal would be received as set forth in the foregoing table with respect to each class of certificates (other than the Class X-A, Class X-B and Class X-C certificates) are based on the assumptions set forth under “Yield and Maturity Considerations—Weighted Average Life” in this free writing prospectus and on the assumptions that there are no prepayments, modifications or losses in respect of the mortgage loans and that there are no extensions or forbearances of maturity dates of the mortgage loans.

	(5)	Ratings shown are those of Moody’s Investors Service, Inc. and Fitch Ratings, Inc. Certain nationally recognized statistical rating organizations that were not hired by the depositor may use information they receive pursuant to Rule 17g-5 under the Securities Exchange Act of 1934, as amended, or otherwise to rate the offered certificates. There can be no assurance as to what ratings a non-hired nationally recognized statistical rating organization would assign. See “Risk Factors—Ratings of the Certificates” and “Ratings” in this free writing prospectus. Moody’s Investors Service, Inc. and Fitch Ratings, Inc. have informed us that the “sf” designation in their ratings represents an identifier for structured finance product ratings. For additional information about this identifier, prospective investors can go to www.moodys.com and/or www.fitchratings.com. Important disclaimer: Credit ratings referenced throughout this material are forward-looking opinions about credit risk and express an agency’s opinion about the ability of and willingness of an issuer of securities to meet its financial obligations in full and on time. Ratings are not indications of investment merit and are not buy, sell or hold recommendations, a measure of asset value, or an indication of the suitability of an investment.

	(6)	The pass-through rate applicable to the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class A-S, Class B, Class C, Class D, Class E, Class F, Class G and Class NR certificates on each distribution date will be a per annum rate equal to one of (i) a fixed rate, (ii) the weighted average of the net mortgage rates on the mortgage loans (in each case adjusted, if necessary, to accrue on the basis of a 360-day year consisting of twelve 30-day months), (iii) the lesser of a specified fixed pass-through rate and the rate described in clause (ii) above or (iv) the rate described in clause (ii) above less a specified percentage.

	(7)	The notional amount of the Class X-A certificates will be equal to the aggregate of the certificate balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB and Class A-S certificates. The notional amount of the Class X-B certificates will be equal to the aggregate of the certificate balances of the Class B and Class C certificates. The Class X-A and Class X-B certificates will not be entitled to distributions of principal.

	(8)	The pass-through rate for the Class X-A certificates for any distribution date will equal the excess, if any, of (a) the weighted average of the net mortgage rates on the mortgage loans (in each case adjusted, if necessary, to accrue on the basis of a 360-day year consisting of twelve 30-day months), over (b) the weighted average of the pass-through rates on the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB and Class A-S certificates, weighted on the basis of their respective certificate balances immediately prior to that distribution date. The pass-through rate for the Class X-B certificates for any distribution date will equal the excess, if any, of (a) the weighted average of the net mortgage rates on the mortgage loans (in each case adjusted, if necessary, to accrue on the basis of a 360-day year consisting of twelve 30-day months), over (b) the weighted average of the pass-through rates on the Class B and Class C certificates, weighted on the basis of their respective certificate balances immediately prior to that distribution date. See “Description of the Certificates—Distributions” in this free writing prospectus.

The corporate trust office of Wells Fargo Bank, National Association is located at 9062 Old Annapolis Road, Columbia, Maryland 21045.

	Sponsors		JPMorgan Chase Bank, National Association, a national banking association and Barclays Bank PLC, a public limited company registered in England and Wales. For more information, see “Transaction Parties—The Sponsors and Mortgage Loan Sellers” in this free writing prospectus and “The Sponsor” in the prospectus.

	Senior Trust Advisor		Pentalpha Surveillance LLC, a Delaware limited liability company, will be the senior trust advisor. During such time as (x) the Class F certificates have a certificate balance (taking into account the application of appraisal reductions to notionally reduce the certificate balance of such class of certificates) of less than 25% of the initial certificate balance of the Class F certificates or (y) a holder of the Class F certificates is the majority controlling class certificateholder and has irrevocably waived its right to exercise any of its rights as the controlling class certificateholder and such rights have not been reinstated to a successor controlling class certificateholder, the senior trust advisor will generally be required to review the special servicer’s operational practices in respect of specially serviced mortgage loans to formulate an opinion as to whether or not those operational practices generally satisfy the servicing standard with respect to the resolution and/or liquidation of specially serviced mortgage loans. In addition, during such time, the senior trust advisor will consult on a non-binding basis with the special servicer with regard to certain matters with respect to the servicing of specially serviced mortgage loans to the extent set forth in the pooling and servicing agreement and described in this free writing prospectus. See “Transaction Parties—The Senior Trust Advisor” in this free writing prospectus.

			From time to time and under certain circumstances, the senior trust advisor, in order to maintain its familiarity with the mortgage loans, is required to review promptly certain information available to privileged persons regarding the mortgage loans and certain asset status reports; however, the senior trust advisor generally will not be involved in any assessment of specific actions of the special servicer or be obligated to deliver any reports or otherwise provide feedback to investors as to any specific actions of the special servicer and, in any event, will be subject to limitations set forth in the pooling and servicing agreement and described in this free writing prospectus.

			From time to time and under certain circumstances, the senior trust advisor will also prepare an annual report to be provided to the certificate administrator for the benefit of the certificateholders setting forth its assessment of the special servicer’s performance of its duties under the pooling and servicing agreement on a platform-level basis with respect to the resolution and liquidation of specially serviced mortgage loans.

			After the occurrence of a consultation termination event, if the senior trust advisor determines the special servicer is not performing its duties as required under the pooling and servicing agreement or is otherwise not acting in accordance with the servicing standard, the senior trust advisor may recommend the replacement of the special servicer as described under “Transaction Parties—Replacement of the Special Servicer” in this free writing prospectus.

			For additional information regarding the responsibilities of the senior trust advisor see “Servicing of the Mortgage Loans—The Senior Trust Advisor” in this free writing prospectus.

			The senior trust advisor will be entitled to a fee payable on each distribution date calculated on the outstanding principal amount of each mortgage loan in the trust fund and the senior trust advisor fee rate, and will have certain rights to indemnification for certain expenses by the trust fund. The senior trust advisor will also be entitled under certain circumstances to a consulting fee. See “Servicing of the Mortgage Loans—The Senior Trust Advisor” in this free writing prospectus.

			Notwithstanding the foregoing, the senior trust advisor will have no obligations or consultation rights under the pooling and servicing agreement for this transaction with respect to the 589 Fifth Avenue whole loan or any related REO property. However, Pentalpha Surveillance LLC is also the senior trust advisor under the 2013-C13 pooling and servicing agreement and, in such capacity, will have certain consultation rights with respect to the 589 Fifth Avenue whole loan that are substantially similar to those of the senior trust advisor under the pooling and servicing agreement for this transaction. See “Description of the Mortgage Pool—The 589 Fifth Avenue Whole Loan” in this free writing prospectus.

	Directing Certificateholder		With respect to each mortgage loan (other than the non-serviced mortgage loan), the directing certificateholder will be the


			controlling class certificateholder selected by more than 50% of the controlling class certificateholders (by certificate balance, as certified by the certificate registrar from time to time as provided for in the pooling and servicing agreement), or a representative thereof.

			The controlling class will be the most subordinate class of the Class F, Class G and Class NR certificates then outstanding that has an aggregate certificate balance, as notionally reduced by any appraisal reductions allocable to such class, at least equal to 25% of the initial certificate balance of that class; provided, however, that during such time as the Class F certificates would be the controlling class, the holders of such certificates will have the right to irrevocably waive their personal right to appoint a directing certificateholder or to exercise any of the rights of the controlling class certificateholder (including the consent and consultation rights described below). No class of certificates, other than as described above, will be eligible to act as the controlling class or appoint a directing certificateholder.

			The directing certificateholder will have certain consent and consultation rights under the pooling and servicing agreement in certain circumstances with respect to the mortgage loans (other than the non-serviced mortgage loan); provided that, after and during such time as the Class F certificates have a certificate balance (taking into account the application of appraisal reductions to notionally reduce the certificate balance of such class of certificates) of less than 25% of the initial certificate balance, the consent rights will terminate. After such time that none of the Class F, Class G and Class NR certificates has a then-outstanding certificate balance at least equal to 25% of the initial certificate balance of that class without regard to the application of any appraisal reductions, the consultation rights of the directing certificateholder will terminate.

			Saba Capital Management L.P., the directing certificateholder under the 2013-C13 pooling and servicing agreement, will have certain consent and consultation rights with respect to the 589 Fifth Avenue mortgage loan that are substantially similar to those of the directing certificateholder under the pooling and servicing agreement. See “Description of the Mortgage Pool—The 589 Fifth Avenue Whole Loan” in this free writing prospectus.

			It is anticipated that BlackRock Financial Management Inc. (or its affiliate) will be the initial directing certificateholder with respect to each mortgage loan (other than the non-serviced mortgage loan); however, we cannot assure you that that arrangement will continue. See “Risk Factors—Potential Conflicts of Interest—Potential Conflicts of Interest of the Directing Certificateholder” in this free writing prospectus.

Morgan Chase Commercial Mortgage Securities Corp. is the depositor and a wholly-owned subsidiary of JPMorgan Chase Bank, National Association.

Certain of the mortgage loans that RAIT Funding, LLC originated that will be included in the trust are subject to that repurchase facility.

Pass-Through Rates

A. Offered Certificates	Your certificates will accrue interest at an annual rate called a pass-through rate. The initial approximate pass-through rate is set forth below for each class:

	Class A-1		%
	Class A-2		%
	Class A-3		%
	Class A-4		%
	Class A-SB		%
	Class X-A		%(1)
	Class X-B		%(2)
	Class A-S		%
	Class B		%
	Class C		%


	(1)	The interest accrual amount on the Class X-A certificates will be calculated by reference to a notional amount equal to the aggregate of the certificate balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB and Class A-S certificates. The pass-through rate for the Class X-A certificates for any distribution date will equal the excess, if any, of (a) the weighted average of the net mortgage rates on the mortgage loans (in each case adjusted, if necessary, to accrue on the basis of a 360-day year consisting of twelve 30-day months) for the related distribution date, over (b) the weighted average of the pass-through rates on the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB and Class A-S certificates weighted on the basis of their respective certificate balances immediately prior to that distribution date as described under “Description of the Certificates—Distributions” in this free writing prospectus.

	(2)	The interest accrual amount on the Class X-B certificates will be calculated by reference to a notional amount equal to the aggregate of the certificate balances of the Class B and Class C certificates. The pass-through rate for the Class X-B certificates for any distribution date will equal the excess, if any, of (a) the weighted average of the net mortgage rates on the mortgage loans (in each case, adjusted, if necessary, to accrue on the basis of a 360-day year consisting of twelve 30-day months) for the related distribution date, over (b) the weighted average of the pass-through rates on the Class B and Class C certificates, weighted on the basis of their respective certificate balances immediately prior to that distribution date as described under “Description of the Certificates—Distributions” in this free writing prospectus.

B. Interest Rate Calculation
Convention	Interest on the offered certificates will be calculated based on a 360-day year consisting of twelve 30-day months, or a “30/360 basis”.

	For purposes of calculating the pass-through rates on the offered certificates, the interest rate for each mortgage loan that accrues interest based on the actual number of days in each month and assuming a 360-day year, or an “actual/360 basis”, will be recalculated, if necessary, so that the amount of interest that would accrue at that recalculated rate in the applicable month, calculated on a 30/360 basis, will equal the amount of interest that is required to be paid on that mortgage loan in that month, subject to certain adjustments as described in “Description of the Certificates—Distributions—Pass-Through Rates” and “—Interest Distribution Amount” in this free writing prospectus.


	C. Servicing and
	Administration Fees		The master servicer and special servicer are entitled to a master servicing fee and a special servicing fee, respectively, from the interest payments on each mortgage loan and with respect to special servicing fees, if the related loan interest payments (or other collections in respect of the related loan or property) are insufficient, then from general collections on all mortgage loans. The servicing fee for each distribution date pursuant to the pooling and servicing agreement, which includes the master servicing fee and the portion of the servicing fee payable to the primary servicer, is calculated on the outstanding principal amount of each mortgage loan (including the non-serviced mortgage loan) in the trust at the servicing fee rate equal to a per annum rate ranging from 0.0050% to 0.0850%. The special servicing fee for each distribution date is calculated based on the outstanding principal amount of each mortgage loan that is a specially serviced mortgage loan or REO Loan at the special servicing fee rate equal to a per annum rate of 0.25%; provided, however, that the special servicer will not be entitled to a special servicing fee with respect to the non-serviced mortgage loan other than any special servicing fees which accrued prior to any mortgage loan becoming a non-serviced mortgage loan, and with respect to the non-serviced mortgage loan, the special servicer under the 2013-C13 pooling and servicing agreement will be entitled to a special servicing fee of 0.25% per annum in accordance with the 2013-C13 pooling and servicing agreement. Any primary servicing fees or sub-servicing fees will be paid by the master servicer or special servicer, respectively, out of the fees described above. The master servicer and special servicer are also entitled to additional fees and amounts, including income on the amounts held in certain accounts and certain permitted investments, liquidation fees and workout fees. See “Transaction Parties—Servicing and Other Compensation and Payment of Expenses” in this free writing prospectus.

			The certificate administrator fee for each distribution date is calculated on the outstanding principal amount of each mortgage loan (including the non-serviced mortgage loan) in the trust fund at the certificate administrator fee rate equal to a per annum rate of 0.00392%. The trustee fee is payable by the certificate administrator from the certificate administrator fee. The senior trust advisor will be entitled to a fee on each distribution date calculated on the outstanding principal amount of each mortgage loan in the trust fund and at the senior trust advisor fee rate, which will be a per annum rate of 0.00175%. The senior trust advisor will also be entitled under certain circumstances to a consulting fee. Fees payable by the trust to the master servicer, special servicer and senior trust advisor are generally payable prior to any distributions to certificateholders. See “Transaction Parties—Servicing and Other Compensation and Payment of Expenses” and “Servicing of the Mortgage Loans—The Senior Trust Advisor” in this free writing prospectus.

			Additionally, with respect to each distribution date, an amount equal to the product of 0.0005% per annum multiplied by the outstanding principal amount of each mortgage loan and any


			REO loan (but not any companion loan) in the trust will be payable to the Commercial Real Estate Finance Council as a license fee for use of their names and trademarks, including an investor reporting package. This fee will be payable prior to any distributions to certificateholders.

	Distributions

	A. Amount and Order of
	Distributions		On each distribution date, funds available for distribution from the mortgage loans, net of specified trust fees, reimbursements, expenses and yield maintenance charges or other prepayment premiums will be distributed to the certificates in the following amounts and order of priority:

			First/Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class X-B and Class X-C certificates: To pay interest on the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class X-B and Class X-C certificates, pro rata, in each case in accordance with their interest entitlements.

			Second/Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates: To the extent of funds allocated to principal and available for distribution: (a) first, to principal on the Class A-SB certificates, until the certificate balance of the Class A-SB certificates is reduced to the planned principal balance for the related distribution date set forth in Annex E to this free writing prospectus, (b) second, to principal on the Class A-1 certificates, until the certificate balance of the Class A-1 certificates has been reduced to zero, (c) third, to principal on the Class A-2 certificates, until the certificate balance of the Class A-2 certificates has been reduced to zero, (d) fourth, to principal on the Class A-3 certificates, until the certificate balance of the Class A-3 certificates has been reduced to zero, (e) fifth, to principal on the Class A-4 certificates, until the certificate balance on the Class A-4 certificates has been reduced to zero, and (f) sixth, to principal on the Class A-SB certificates, until the certificate balance of the Class A-SB certificates has been reduced to zero. If the certificate balance of each class of certificates other than the Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates has been reduced to zero as a result of the allocation of mortgage loan losses to those certificates, funds available for distributions of principal will be distributed to the Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates, pro rata, without regard to the distribution priorities described above or the planned principal balance of the Class A-SB certificates.

			Third/Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates: To reimburse the Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates, pro rata, for any previously unreimbursed losses on the mortgage loans allocable to principal that were previously borne by those classes.

			Fourth/Class A-S certificates: To the Class A-S certificates as follows: (a) first, to interest on the Class A-S certificates, in an


			amount up to their interest entitlement; (b) second, to the extent of funds allocated to principal and available for distribution remaining after distributions in respect of principal to each class with a higher priority (in this case, the Class A-1, Class A-2, Class A-3, Class A-4 and Class A-SB certificates), to principal on the Class A-S certificates, until the certificate balance of the Class A-S certificates has been reduced to zero; and (c) third, to reimburse the Class A-S certificates, for any previously unreimbursed losses on the mortgage loans allocable to principal that were previously borne by that class.

			Fifth/Class B certificates: To the Class B certificates in a manner analogous to the Class A-S certificates’ allocations of priority Fourth above.

			Sixth/Class C certificates: To the Class C certificates in a manner analogous to the Class A-S certificates’ allocations of priority Fourth above.

			Seventh/Non-offered certificates (other than the Class X-C certificates): In the amounts and order of priority described in “Description of the Certificates—Distributions” in this free writing prospectus.

	B. Interest and Principal
	Entitlements		A description of the interest entitlement of each class of certificates (other than the Class R certificates) can be found in “Description of the Certificates—Distributions—Interest Distribution Amount” in this free writing prospectus.

			A description of the amount of principal required to be distributed to each class of certificates entitled to principal on a particular distribution date can be found in “Description of the Certificates—Distributions—Principal Distribution Amount” in this free writing prospectus.

	C. Yield Maintenance Charges and
	Prepayment Premiums		Yield maintenance charges and prepayment premiums with respect to the mortgage loans will be allocated to the certificates as described in “Description of the Certificates—Allocation of Yield Maintenance Charges and Prepayment Premiums” in this free writing prospectus.

			For an explanation of the calculation of yield maintenance charges, see “Description of the Mortgage Pool—Certain Terms and Conditions of the Mortgage Loans” in this free writing prospectus.

	D. General		The chart below describes the manner in which the payment rights of certain classes of certificates will be senior or subordinate, as the case may be, to the payment rights of other classes of certificates. The chart shows the entitlement to receive principal and/or interest of certain classes of certificates (other than excess interest that accrues on each mortgage loan that has an anticipated repayment date) on any distribution date in descending order. It also shows the manner in which mortgage loan losses are allocated to certain classes of the


	certificates in ascending order (beginning with the non-offered certificates, other than the Class R certificates); provided that no principal payments or mortgage loan losses will be allocated to the Class X-A, Class X-B, Class X-C or Class R certificates, although principal payments and mortgage loan losses may reduce the notional amount of the Class X-A, Class X-B or Class X-C certificates and, therefore, the amount of interest they accrue.



	(1)	The Class X-A, Class X-B and Class X-C certificates are interest-only certificates and the Class X-C certificates are not offered by this free writing prospectus.

	(2)	Other than the Class X-C and Class R certificates.

	Other than the subordination of certain classes of certificates, as described above, no other form of credit enhancement will be available for the benefit of the holders of the certificates offered hereby.

	Principal losses (and principal payments, if any) on mortgage loans that are allocated to a class of certificates (other than the Class X-A, Class X-B, Class X-C or Class R certificates) will reduce the certificate balance of that class of certificates.

	The notional amount of the Class X-A certificates will be reduced by the amount of principal losses or principal payments, if any, allocated to the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB and Class A-S certificates. The notional amount of the Class X-B certificates will be reduced by the amount of principal losses or payments, if any, allocated to the Class B and Class C certificates. The notional amount of the Class X-C certificates will be reduced by the amount of principal losses or payments, if any, allocated to the Class F, Class G and Class NR certificates.

	See “Description of the Certificates” in this free writing prospectus.

E. Shortfalls in Available Funds	The following types of shortfalls in available funds will reduce distributions to the classes of certificates with the lowest


			payment priorities: shortfalls resulting from the payment of special servicing fees and other additional compensation that the special servicer is entitled to receive; shortfalls resulting from interest on advances made by the master servicer, the special servicer or the trustee (to the extent not covered by late payment charges or default interest paid by the related borrower); shortfalls resulting from the application of appraisal reductions to reduce principal and interest advances; shortfalls resulting from extraordinary expenses of the trust, including indemnification payments payable to the depositor, master servicer, special servicer, certificate administrator, trustee or senior trust advisor; shortfalls resulting from a modification of a mortgage loan’s interest rate or principal balance; and shortfalls resulting from other unanticipated or default-related expenses of the trust. Prepayment interest shortfalls on the mortgage loans that are not covered by certain compensating interest payments made by the master servicer are required to be allocated among the classes of certificates (other than the Class R certificates), on a pro rata basis, to reduce the amount of interest payable on each such class of certificates to the extent described in this free writing prospectus. See “Description of the Certificates—Distributions— Priority” in this free writing prospectus.

	F. Excess Interest		On each distribution date, any excess interest in respect of the increase in the interest rate on any mortgage loan with an anticipated repayment date after the related anticipated repayment date to the extent actually collected and applied as interest during a due period will be distributed to the holders of the Class NR certificates on the related distribution date. This excess interest will not be available to make distributions to any other class of certificates or to provide credit support for other classes of certificates or offset any interest shortfalls or to pay any other amounts to any other party under the pooling and servicing agreement. The Class NR certificates will be entitled to such distributions of excess interest notwithstanding any reduction of their related certificate balance to zero.

	Advances

	A. P&I Advances		The master servicer is required to advance a delinquent periodic mortgage loan payment (unless the master servicer or the special servicer determines that the advance would be non-recoverable). Neither the master servicer nor the trustee will be required to advance balloon payments due at maturity in excess of the regular periodic payment, interest in excess of a mortgage loan’s regular interest rate, default interest, late payment charges, prepayment premiums or yield maintenance charges. The amount of the interest portion of any advance will be subject to reduction to the extent that an appraisal reduction of the related mortgage loan has occurred (and with respect to any mortgage loan that is part of a split loan structure, to the extent such appraisal reduction amount is allocated to the related mortgage loan). See “Description of the Certificates—Advances” in this free writing prospectus. There may be other circumstances in which the master servicer will not be required to advance a full month of principal and/or interest. If the master


	servicer fails to make a required advance, the trustee will be required to make the advance, unless the trustee determines that the advance would be non-recoverable. See “Description of the Certificates—Advances” in this free writing prospectus. If an interest advance is made by the master servicer, the master servicer will not advance its servicing fee, but will advance the certificate administrator’s fee. See “Description of the Certificates—Advances” in this free writing prospectus. None of the master servicer, special servicer or trustee will make, or be permitted to make, any principal or interest advance with respect to any companion loan that is not part of the trust.

B. Property Protection Advances	The master servicer may be required, and the special servicer may be permitted, to make advances with respect to mortgage loans that it is required to service to pay delinquent real estate taxes, assessments and hazard insurance premiums and similar expenses necessary to:

	●	protect and maintain (and in the case of REO properties, lease and manage) the related mortgaged property;

	●	maintain the lien on the related mortgaged property; and/or

	●	enforce the related mortgage loan documents.

	If the master servicer fails to make a required advance of this type, the trustee will be required to make this advance. None of the master servicer, the special servicer or the trustee is required to advance amounts determined by such party to be non-recoverable. See “Description of the Certificates—Advances” in this free writing prospectus.

C. Interest on Advances	The master servicer, the special servicer and the trustee, as applicable, will be entitled to interest on the above described advances at the “Prime Rate” as published in The Wall Street Journal, as described in this free writing prospectus. Interest accrued on outstanding advances may result in reductions in amounts otherwise payable on the certificates. Neither the master servicer nor the trustee will be entitled to interest on advances made with respect to principal and interest due on a mortgage loan until the related due date has passed and any grace period for late payments applicable to the mortgage loan has expired. See “Description of the Certificates—Advances” and “—Subordination; Allocation of Collateral Support Deficit” in this free writing prospectus.

	The Mortgage Loans

The Mortgage Pool	The trust’s primary assets will be 45 fixed rate commercial mortgage loans, each evidenced by one or more promissory notes secured by first mortgages, deeds of trust, deeds to secure debt or similar security instruments on the fee and/or leasehold estate of the related borrower in 89 commercial, multifamily and manufactured housing properties; provided, however, that with respect to the mortgage loan referred to as Hyatt Regency Cleveland on Annex A-1 to this free writing prospectus, such mortgage loan will not be secured by a first lien. See “Description


			of the Mortgage Pool—Additional Debt” in this free writing prospectus.

			The aggregate principal balance of the mortgage loans as of the cut-off date will be approximately $1,148,151,830.

			Pari Passu Split Loans

			Four (4) mortgage loans (identified as Loan Nos. 1, 3, 4 and 5 on Annex A-1 to this free writing prospectus), representing approximately 30.9% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, are each part of a pari passu split loan structure.

			In the case of the mortgage loan referred to in this free writing prospectus as the Meadows Mall mortgage loan (identified as Loan No. 1 on Annex A-1 to this free writing prospectus), representing approximately 9.6% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, such mortgage loan is secured by the same mortgage instrument on the same mortgaged property as a related pari passu companion loan, which companion loan is evidenced by a pari passu note that is not part of the trust, and is referred to in this free writing prospectus as the Meadows Mall pari passu companion loan.

			In the case of the mortgage loan referred to in this free writing prospectus as the 589 Fifth Avenue mortgage loan (identified as Loan No. 3 on Annex A-1 to this free writing prospectus), representing approximately 7.6% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, such mortgage loan is secured by the same mortgage instrument on the same mortgaged property as a related pari passu companion loan, which companion loan is evidenced by a pari passu note that is not part of the trust, and is referred to in this free writing prospectus as the 589 Fifth Avenue pari passu companion loan.

			In the case of the mortgage loan referred to in this free writing prospectus as the SanTan Village mortgage loan (identified as Loan No. 4 on Annex A-1 to this free writing prospectus), representing approximately 7.2% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, such mortgage loan is secured by the same mortgage instrument on the same mortgaged property as a related pari passu companion loan, which companion loan is evidenced by a pari passu note that is not part of the trust, and is referred to in this free writing prospectus as the SanTan Village pari passu companion loan.

			In the case of the mortgage loan referred to in this free writing prospectus as the Southridge Mall mortgage loan (identified as Loan No. 5 on Annex A-1 to this free writing prospectus), representing approximately 6.5% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, such mortgage loan is secured by the same mortgage instrument on the same mortgaged property as a related pari passu companion loan, which companion loan is evidenced by a pari passu note that is not part of the trust, and is referred to in this free writing prospectus as the Southridge Mall pari passu companion loan.


			Each mortgage loan identified in the above table is included in the trust; in each instance the related pari passu companion loan is not included in the trust. In the case of the Southridge Mall pari passu companion loan, the related pari passu companion loan is included in the JPMBB Commercial Mortgage Securities Trust 2013-C12. In the case of the 589 Fifth Avenue pari passu companion loan and the SanTan Village pari passu companion loan, each related pari passu companion loan is included in the J.P. Morgan Chase Commercial Mortgage Securities Trust 2013-C13. In the case of the Meadows Mall pari passu companion loan, the pari passu companion loan is expected to be deposited into a future securitization. In each instance, the related pari passu companion loan is pari passu in right of payment with the related mortgage loan.

			The 589 Fifth Avenue mortgage loan and the 589 Fifth Avenue pari passu companion loan will be serviced under the 2013-C13 pooling and servicing agreement. In addition, pursuant to the related intercreditor agreement, the directing certificateholder under that securitization may exercise certain rights granted to the holder of the 589 Fifth Avenue pari passu companion loan, and therefore will have the right, subject to certain conditions set forth in the related intercreditor agreement, to advise and direct the 2013-C13 master servicer and/or the 2013-C13 special servicer with respect to various servicing matters or mortgage loan modifications affecting the 589 Fifth Avenue mortgage loan in that split loan structure. See “Description of the Mortgage Pool—The 589 Fifth Avenue Whole Loan” in this free writing prospectus.

			Each of (a) the Meadows Mall mortgage loan and the Meadows Mall pari passu companion loan, (b) the SanTan Village mortgage loan and the SanTan Village pari passu companion loan and (c) the Southridge Mall mortgage loan and the Southridge Mall pari passu companion loan will be serviced in accordance with the pooling and servicing agreement for this transaction by the master servicer and the special servicer, and in accordance with the servicing standard provided in such pooling and servicing agreement. In addition, pursuant to the related intercreditor agreement, the directing certificateholder may exercise certain rights granted to the holder of the Meadows Mall mortgage loan, the SanTan Village mortgage loan or the Southridge Mall mortgage loan, as applicable, and therefore will have the right, subject to certain conditions set forth in the related intercreditor agreement, to advise and direct the master servicer and/or special servicer with respect to various servicing


			matters or mortgage loan modifications affecting the applicable mortgage loan in the related split loan structure. See “Description of the Mortgage Pool—The Meadows Mall Whole Loan”, “—The SanTan Village Whole Loan” and “—The Southridge Mall Whole Loan” in this free writing prospectus.

			Each of the Meadows Mall whole loan, the SanTan Village whole loan and the Southridge Mall whole loan is referred to in this free writing prospectus as a “serviced whole loan”.

			The 589 Fifth Avenue whole loan is referred to in this free writing prospectus as a “non-serviced whole loan”. For additional information regarding this pari passu split loan, see “Description of the Mortgage Pool—The 589 Fifth Avenue Whole Loan” in this free writing prospectus.

			The following tables set forth certain anticipated characteristics of the mortgage loans as of the cut-off date (unless otherwise indicated). Except as specifically provided in this free writing prospectus, information presented in this free writing prospectus (including loan-to-value ratios, debt service coverage ratios and debt yield ratios) with respect to any mortgage loan with a pari passu companion loan is calculated including the principal balance and debt service payment of the related pari passu companion loan.

			The sum of the numerical data in any column may not equal the indicated total due to rounding. Unless otherwise indicated, all figures and percentages presented in this “Summary of Terms” are calculated as described under “Description of the Mortgage Pool—Additional Mortgage Loan Information” in this free writing prospectus and, unless otherwise indicated, such figures and percentages are approximate and in each case, represent the indicated figure or percentage of the aggregate principal balance of the pool of mortgage loans as of the cut-off date. The principal balance of each mortgage loan as of the cut-off date assumes the timely receipt of principal scheduled to be paid on or before the cut-off date and no defaults, delinquencies or prepayments on, or modifications of, any mortgage loan on or prior to the cut-off date. Whenever percentages and other information in this free writing prospectus are presented on the mortgaged property level rather than the mortgage loan level, the information for mortgage loans secured by more than one mortgaged property is based on allocated loan amounts as stated in Annex A-1 to this free writing prospectus.

			(5)	In the case of one (1) mortgage loan (identified as Loan No. 18 on Annex A-1 to this free writing prospectus), representing approximately 1.7% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, the loan-to-value ratio was based upon a basis other than the appraised “as-is” value. For further information see Annex A-1 to this free writing prospectus. See “Risk Factors—Limitations of Appraisals” and “Transaction Parties—The Sponsors and Mortgage Loan Sellers—JPMorgan Chase Bank, National Association—Exceptions to JPMCB’s Disclosed Underwriting Guidelines” in this free writing prospectus. The remaining mortgage loans were calculated using “as-is” values as described under “Description of the Mortgage Pool—Additional Mortgage Loan Information” in this free writing prospectus.

			(6)	For each mortgage loan with a related pari passu companion loan, the calculation of the loan-to-value ratios and debt service coverage ratios includes the principal balance and debt service payment of the related pari passu companion loan.

			(7)	For each partial interest-only loan, the debt service coverage ratio was calculated based on the first principal and interest payment to be made into the trust during the term of the mortgage loan once amortization has commenced. For all interest-only loans, the debt service coverage ratio was calculated based on the sum of the first 12 interest payments following the cut-off date. With respect to thirty-six (36) mortgaged properties (identified as Loan Nos. 1, 2, 3, 4, 5, 14, 16, 23, 25, 26 and 29 on Annex A-1 to this free writing prospectus) securing eleven (11) mortgage loans, representing approximately 48.2% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date by allocated loan amount, certain assumptions and/or adjustments were made to the occupancy, underwritten net cash flow and underwritten net cash flow debt service coverage ratios reflected in the table above. For specific discussions on those particular assumptions and adjustments, see “Description of the Mortgage Pool—Net Cash Flow and Certain Underwriting Considerations”, “—Mortgaged Property Considerations—Tenant Issues—Occupancy and Tenant Concentrations” and “—Additional Mortgage Loan Information” in this free writing prospectus. See also Annex A-1 and Annex A-3 to this free writing prospectus.

			(8)	With respect to Loan No. 12, representing approximately 2.3% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, the debt service coverage ratios were calculated using the average of the first 12 monthly payments of principal and interest after the cut-off date based on the planned amortization schedule attached as Annex F to this free writing prospectus.


			Two (2) mortgage loans (identified as Loan Nos. 17 and 37 on Annex A-1 to this free writing prospectus), representing approximately 2.4% of the aggregate principal balance of the pool of mortgage loans as of the cut-off date, provide for an increase in the related interest rate after, and otherwise provide incentives to the borrowers to repay the mortgage loan by, a certain date, referred to as the anticipated repayment date. The interest accrued in excess of the original rate, together with any interest on that accrued interest (if any, as required by the mortgage loan documents and to the extent permitted by applicable law), will be deferred and will not be paid until the principal balance of the mortgage loan has been paid, at which time the excess interest, to the extent actually collected, will be required to be paid to the Class NR certificates. After the anticipated repayment date, cash flow in excess of that required for debt service and certain budgeted expenses with respect to the mortgaged property would be applied towards the payment of principal (without payment of a yield maintenance charge or prepayment premium) of the mortgage loan until its principal balance has been reduced to zero and then to the payment of accrued excess interest. A substantial principal payment will be required to pay off each mortgage loan on its anticipated repayment date. The actual term for each mortgage loan is longer than the period up to the mortgage loan’s anticipated repayment date.

	Transaction Overview

	On the closing date, each sponsor will sell its respective mortgage loans to the depositor, which will in turn deposit the mortgage loans into the issuing entity, a common law trust created on the closing date. The trust, which will be the issuing entity, will be formed by a pooling and servicing agreement, to be entered into among the depositor, the master servicer, the special servicer, the certificate administrator, the trustee and the senior trust advisor. The master servicer will service the mortgage loans (other than the specially serviced mortgage loans and the non-serviced mortgage loan) in accordance with the pooling and servicing agreement and provide the information to the certificate administrator necessary for the certificate administrator to calculate distributions and other information regarding the certificates.

	The transfers of the mortgage loans from the sponsors to the depositor and from the depositor to the issuing entity in exchange for the offered certificates are illustrated below:
