+Your use of this Program is governed by the No-Fee Terms and Conditions set
+forth below, unless you have received this Program (alone or as part of another

+Oracle No-Fee Terms and Conditions (NFTC)
+
+Definitions
+
+"Oracle" refers to Oracle America, Inc. "You" and "Your" refers to (a) a company
+or organization (each an "Entity") accessing the Programs, if use of the
+Programs will be on behalf of such Entity; or (b) an individual accessing the
+Programs, if use of the Programs will not be on behalf of an Entity.
+"Program(s)" refers to Oracle software provided by Oracle pursuant to the
+following terms and any updates, error corrections, and/or Program Documentation
+provided by Oracle. "Program Documentation" refers to Program user manuals and
+Program installation manuals, if any. If available, Program Documentation may be
+delivered with the Programs and/or may be accessed from
+www.oracle.com/documentation. "Separate Terms" refers to separate license terms
+that are specified in the Program Documentation, readmes or notice files and
+that apply to Separately Licensed Technology. "Separately Licensed Technology"
+refers to Oracle or third party technology that is licensed under Separate Terms
+and not under the terms of this license.
+
+Separately Licensed Technology
+
+Oracle may provide certain notices to You in Program Documentation, readmes or
+notice files in connection with Oracle or third party technology provided as or
+with the Programs. If specified in the Program Documentation, readmes or notice
+files, such technology will be licensed to You under Separate Terms. Your rights
+to use Separately Licensed Technology under Separate Terms are not restricted in
+any way by the terms herein. For clarity, notwithstanding the existence of a
+notice, third party technology that is not Separately Licensed Technology shall
+be deemed part of the Programs licensed to You under the terms of this license.
+
+Source Code for Open Source Software
+
+For software that You receive from Oracle in binary form that is licensed under
+an open source license that gives You the right to receive the source code for
+that binary, You can obtain a copy of the applicable source code from
+https://oss.oracle.com/sources/ or http://www.oracle.com/goto/opensourcecode. If
+the source code for such software was not provided to You with the binary, You
+can also receive a copy of the source code on physical media by submitting a
+written request pursuant to the instructions in the "Written Offer for Source
+Code" section of the latter website.

+The following license terms apply to those Programs that are not provided to You
+under Separate Terms.
+
+License Rights and Restrictions
+
+Oracle grants to You, as a recipient of this Program, subject to the conditions
+stated herein, a nonexclusive, nontransferable, limited license to:

+(a) internally use the unmodified Programs for the purposes of developing,
+testing, prototyping and demonstrating your applications, and running the
+Program for Your own personal use or internal business operations; and
+
+(b) redistribute the unmodified Program and Program Documentation, under the
+terms of this License, provided that You do not charge Your licensees any fees
+associated with such distribution or use of the Program, including, without
+limitation, fees for products that include or are bundled with a copy of the
+Program or for services that involve the use of the distributed Program.
+
+You may make copies of the Programs to the extent reasonably necessary for
+exercising the license rights granted herein and for backup purposes. You are
+granted the right to use the Programs to provide third party training in the use
+of the Programs and associated Separately Licensed Technology only if there is
+express authorization of such use by Oracle on the Program's download page or in
+the Program Documentation.

+
+- You do not remove markings or notices of either Oracle's or a licensor's
+  proprietary rights from the Programs or Program Documentation;
+
+- You comply with all U.S. and applicable export control and economic sanctions
+  laws and regulations that govern Your use of the Programs (including technical
+  data);
+
+- You do not cause or permit reverse engineering, disassembly or decompilation
+  of the Programs (except as allowed by law) by You nor allow an associated
+  party to do so.
+
+For clarity, any source code that may be included in the distribution with the
+Programs is provided solely for reference purposes and may not be modified,
+unless such source code is under Separate Terms permitting modification.
+
+Ownership
+
+Oracle or its licensors retain all ownership and intellectual property rights to
+the Programs.
+
+Information Collection
+
+The Programs' installation and/or auto-update processes, if any, may transmit a

+DISCLAIMS ALL WARRANTIES, EXPRESS AND IMPLIED, INCLUDING WITHOUT LIMITATION, ANY
+IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR

+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL ORACLE BE LIABLE TO YOU FOR
+DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT
+LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
