known as COMM 2012-CCRE3 Mortgage Trust (the "Issuing Entity"), effective as of June 21, 2021,
Midland was removed as special servicer and KeyBank National Association ("KeyBank"), a national
banking association, was appointed as the successor special servicer. In its capacity as special
servicer, KeyBank will be responsible for the servicing and administration of the Specially Serviced
Mortgage Loans and REO Properties pursuant to the Pooling and Servicing Agreement, a copy of which
was filed as Exhibit 4.1 to the Current Report on Form 8-K/A filed by the Issuing Entity with the
Securities and Exchange Commission on November 21, 2012.

Capitalized terms used, but not defined, in this Current Report on Form 8-K have the meanings
set forth in the Pooling and Servicing Agreement.

KeyBank National Association

As of June 21, 2021, KeyBank replaced Midland as the special servicer (the "Special Servicer") and
assumed all of the duties, responsibilities, and liabilities of the Special Servicer under the
Pooling and Servicing Agreement.

KeyBank, a national banking association, will act as the Special Servicer under the Pooling and
Servicing Agreement.  KeyBank is a wholly-owned subsidiary of KeyCorp. KeyBank is not an affiliate
of the Issuing Entity, the Depositor, the Mortgage Loan Sellers, the Trustee, the Master Servicer,
the Operating Advisor or the Certificate Administrator. The principal servicing offices of KeyBank
are located at 11501 Outlook Street, Suite 300, Overland Park, Kansas 66211.

KeyBank has been engaged in the servicing of commercial mortgage loans since 1995 and commercial
mortgage loans originated for securitization since 1998.  The following table sets forth information
about KeyBank's portfolio of master or primary serviced commercial mortgage loans as of the dates
indicated.

          Loans			12/31/18	12/31/19	12/31/20	3/31/21
By Approximate Number		16,281		18,882		17,008		17,294
By Approximate Aggregate     	$239.0		$289.6		$308.5		$320.9
Principal Balance (in
billions)

Within this servicing portfolio are, as of March 31, 2021, approximately 10,756 loans with a total
principal balance of approximately $237.0 billion that are included in approximately 764 commercial
mortgage-backed securitization transactions.


KeyBank's servicing portfolio includes mortgage loans secured by multifamily, office, retail,
hospitality, and other types of income-producing properties that are located throughout the
United States. KeyBank also services newly-originated commercial mortgage loans and mortgage
loans acquired in the secondary market for issuers of commercial and multifamily mortgage-backed
securities, financial institutions and a variety of investors and other third parties. Based
on the aggregate outstanding principal balance of loans being serviced as of December 31, 2020,
the Mortgage Bankers Association of America ranked KeyBank the third largest commercial mortgage
loan servicer for loans related to commercial mortgage-backed securities in terms of total
master and primary servicing volume.

KeyBank has been a special servicer of commercial mortgage loans and commercial real estate
assets included in CMBS transactions since 1998. As of March 31, 2021, KeyBank was named as
special servicer with respect to commercial mortgage loans in 373 commercial mortgaged-backed
securities transactions totaling approximately $152.0 billion in aggregate outstanding
principal balance and was special servicing a portfolio that included approximately 173
commercial mortgage loans with an aggregate outstanding principal balance of approximately
$3.048 billion, which portfolio includes multifamily, office, retail, hospitality and
other types of income-producing properties that are located throughout the United States.

The following table sets forth information on the size and growth of KeyBank's managed portfolio
of specially serviced commercial mortgage loans for which KeyBank is the named special servicer
in CMBS transactions in the United States.

KeyBank is approved as the master servicer, primary servicer, and special servicer for
commercial mortgage-backed securities rated by Moody's, S&P, Fitch, and DBRS, Inc.
Moody's does not assign specific ratings to servicers.  KeyBank is on S&P's Select
Servicer list as a U.S. Commercial Mortgage Master Servicer and as a U.S.
Commercial Mortgage Special Servicer, and S&P has assigned to KeyBank the
rating of "Strong" as a master servicer, primary servicer, and special servicer.
Fitch has assigned to KeyBank the ratings of "CMS1" as a master servicer, "CPS1"
as a primary servicer, and "CSS1-" as a special servicer.  DBRS, Inc. has
assigned to KeyBank the rankings of "MOR CS1" as master servicer, "MOR CS1"
as primary servicer, and "MOR CS1" as special servicer.  S&P's, Fitch's, and
DBRS, Inc.'s ratings of a servicer are based on an examination of many factors,
including the servicer's financial condition, management team, organizational
structure, and operating history.

KeyBank's servicing system utilizes a mortgage-servicing technology platform with
multiple capabilities and reporting functions.  This platform allows KeyBank to
process mortgage servicing activities including: (i) performing account maintenance;
(ii) tracking borrower communications; (iii) tracking real estate tax escrows and
payments, insurance escrows and payments, replacement reserve escrows and operating
statement data and rent rolls; (iv) entering and updating transaction data;
and (v) generating various reports.  KeyBank generally uses the CREFC format
to report to trustees and certificate administrators of commercial mortgage-backed
securities (CMBS) transactions and maintains a website (www.keybank.com/key2cre)
that provides access to reports and other information to investors in CMBS
transactions that KeyBank is the servicer.

KeyBank maintains the accounts it uses in connection with servicing commercial
mortgage loans.  The following table sets forth the ratings assigned to KeyBank's
debt obligations and deposits.

				S&P	Fitch	Moody's
Long-Term Debt Obligations	A-	A-	A3
Short-Term Debt Obligations	A-2	F1	P-2
Long-Term Deposits		N/A	A	Aa3
Short-Term Deposits		N/A	F1	P-1

KeyBank believes that its financial condition will not have any material adverse
effect on the performance of its duties under the Pooling and Servicing Agreement
and, accordingly, will not have any material adverse impact on the performance
of the Mortgage Loans or the performance of the Certificates.

KeyBank has developed policies, procedures and controls for the performance of
its master servicing and special servicing obligations in compliance with
applicable servicing agreements, servicing standards and the servicing criteria
set forth in Item 1122 of Regulation AB ("Regulation AB").  These policies,
procedures and controls include, among other things, procedures to (i) notify
borrowers of payment delinquencies and other loan defaults, (ii) work with
borrowers to facilitate collections and performance prior to the occurrence of
a servicing transfer event, (iii) if a servicing transfer event occurs as a
result of a delinquency, loss, bankruptcy or other loan default, transfer the
subject loan to the special servicer, and (iv) managing delinquent loans and
loans subject to the bankruptcy of the borrower.

KeyBank's servicing policies and procedures for the servicing functions it will
perform under the Pooling and Servicing Agreement for assets of the same type
included in this transaction are updated periodically to keep pace with the
changes in the CMBS industry.  For example, KeyBank has, in response to changes
in federal or state law or investor requirements, (i) made changes in its
insurance monitoring and risk-management functions as a result of the
Terrorism Risk Insurance Act of 2002, as amended and (ii) established a
website where investors and mortgage loan borrowers can access information
regarding their investments and mortgage loans.  Otherwise, KeyBank's servicing
policies and procedures have been generally consistent for the last three
years in all material respects.

KeyBank is, as the Special Servicer, generally responsible for the special
servicing functions with respect to the Mortgage Loans and any REO Property.
Additionally, KeyBank may from time to time perform some of its servicing
obligations under the Pooling and Servicing Agreement through one or more
third-party vendors that provide servicing functions such as tracking and
reporting of flood zone changes, performing UCC searches, filing UCC
financing statements and amendments, appraisals, environmental assessments,
property condition assessments, property management, real estate
brokerage services and other services necessary in the routine course of
acquiring, managing and disposing of any REO Property. KeyBank will, in
accordance with its internal procedures and applicable law, monitor
and review the performance of any third-party vendors retained by it
to perform servicing functions, and KeyBank will remain liable for its
servicing obligations under the Pooling and Servicing Agreement as if
KeyBank had not retained any such vendors.

KeyBank will not have primary responsibility for custody services of original
documents evidencing the underlying Mortgage Loans.  KeyBank may from time
to time have custody of certain of such documents as necessary for enforcement
actions involving the Mortgage Loans or otherwise.  To the extent that
KeyBank has custody of any such documents for any such servicing purposes,
such documents will be maintained in a manner consistent with the
Servicing Standard.

No securitization transaction involving commercial or multifamily mortgage
loans in which KeyBank was acting as special servicer has experienced a
servicer event of default as a result of any action or inaction of KeyBank
as special servicer including as a result of KeyBank's failure to comply
with the applicable servicing criteria in connection with any securitization
transaction.  KeyBank has made all advances required to be made by it
under its servicing agreements for commercial and multifamily mortgage loans.

From time to time KeyBank is a party to lawsuits and other legal proceedings
as part of its duties as a loan servicer and otherwise arising in the ordinary
course of its business.  KeyBank does not believe that any lawsuits or legal
proceedings that are pending at this time would, individually or in the aggregate,
have a material adverse effect on its business or its ability to service the
Mortgage Loans pursuant to the Pooling and Servicing Agreement.

KeyBank may enter into one or more arrangements with the applicable Controlling
Class Representative, holders of certificates of the Controlling Class or any
person with the right to appoint or remove and replace the Special Servicer
to provide for a discount and/or revenue sharing with respect to certain of
the special servicing compensation in consideration of, among other things,
KeyBank's appointment as Special Servicer under the Pooling and Servicing
Agreement and any related intercreditor agreement and limitations on such
person's right to replace the Special Servicer.

KeyBank is not aware of any lawsuits or legal proceedings, contemplated
or pending, by governmental authorities against KeyBank at this time.

Neither KeyBank nor any of its affiliates will retain any certificates
issued by the Issuing Entity or any other economic interest in this
securitization. However, KeyBank or its affiliates may own in the future
certain classes of certificates. Any such party will have the right to
dispose of any such certificates at any time.
