The Parties hereby reaffirm their obligation and intent to abide by the terms of Paragraph 15 of the February 6, 2003 Protective Order entered in this
Lawsuit by the Court (the Protective Order), which gives the Parties thirty (30) days after the termination of the Lawsuit to:



| | (i) | destroy or return to the disclosing party, or its attorney of record, the Confidential Information in their possession, custody, or control or in the possession, custody or control
of their staff;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | ensure that all Confidential Information in the possession, custody or control of their experts, is destroyed or returned to the disclosing Party, or its attorney of record;
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | destroy all notes, memoranda or other documents which contain excerpts from any of the Confidential Information;
| | ----- | ----------------------------------------------------------------------------------------------------------------



| | (iv) | consent to the Courts destruction of such Confidential Information, and if the Court is not willing to destroy such Confidential Information, then withdraw from the Court all
Confidential Information filed, lodged, or otherwise delivered to the Court under seal pursuant to Paragraph 9 of the Protective Order; and
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | notwithstanding anything in the Protective Order to the contrary, shall return source code to counsel for the Party disclosing the source code.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------



Notwithstanding any of the foregoing, any Party may retain copies of any
material filed with the Court, and Quests counsel of record may retain one copy of EDBA at its office to be used solely by a third-party expert to determine, in connection with the License Agreement, whether any Quest Software product should
be deemed to be a Royalty Product or a Bundled Royalty Product (as those terms are defined in the License Agreement). Quest Software intends to use Bruce Webster to assist it in proactively reviewing Quest Softwares products in light of EDBA,
which may require Webster to review the EDBA source code. Webster has agreed to continue to abide by the terms of the Protective Order entered in the Lawsuit. Computer Associates agrees that Webster is approved for the purposes of assisting Quest
Software in this regard, without Webster having to execute any additional documents. The Parties agree that the employment restrictions detailed in Section 5 of the Declaration Regarding Receipt of Confidential Information shall continue until one
(1) year after the retained expert returns to Quest Softwares counsel of record all whole or partial copies of EDBA.



If Quest Software desires to retain an expert other than Webster to review EDBA for any reason, each such expert must execute a confidentiality agreement
that contains the restrictions and obligations set forth in the Protective Order entered in the Lawsuit. The Parties agree that the employment restrictions detailed in Section 5 of the Declaration Regarding Receipt of Confidential Information shall
continue until one (1) year after the retained expert returns to



7



---

Quest Softwares counsel of record all whole or partial copies of EDBA. Before any such expert is permitted access to the EDBA source code, the
following three conditions must be met: (1) such expert must be informed of the existence and contents of this Agreement and License Agreement; (2), the expert must be identified to Computer Associates and the confidentiality agreement signed by the
expert must be sent Computer Associates; and (3) Computer Associates will have ten (10) business days after receipt of the experts identity and signed confidentiality agreement to object in good faith, in writing, to disclosure of EDBA to such
expert; if such objection is made, the disclosure shall not be made until the objection is resolved in an arbitration proceeding to be initiated and conducted as provided under the License Agreement. The fee shifting provisions in Section 12.3 of
the License Agreement shall not apply to any arbitration initiated to resolve Computer Associates objections to an expert identified by Quest Software under this Section.



10. Representations and Warranties.



a. Each Party represents and warrants that the Party has the requisite power and authority and has taken all actions necessary to execute and deliver this

otherwise transferred any right, title, or interest in any Released Claims, and each Party hereby agrees to forever indemnify and hold forever harmless each other Party from all Released Claims, including, but not limited to, attorneys and
expert fees, incurred as a result of any person or entity asserting any such Released Claims against such other Party pursuant to any such assignment or transfer.



c. Quest Software represents and warrants to Computer Associates that: (i) Quest Softwares products, including, but
not limited to, Quest Central for Oracle, Quest Central for SQL Server, and Quest Central for Sybase, but excluding Quest Central for DB2, do not infringe the CA Copyrights or misappropriate the CA Trade Secrets; and (ii) Quest Software is not
funding the payment being made by Jenson under Section 4.



d.
Except for the portions of EDBA that comprise the Licensed Source Code, Quest Software represents and warrants to Computer Associates that, based on a good faith investigation: (i) Quest Software does not believe it has in its possession, custody,
or control any copies of EDBA, except those copies retained by Quest Softwares counsel of record or outside retained experts in the Lawsuit; and (ii) Quest Software will not use EDBA after the Effective



8



---

Date. If Quest Software later becomes aware of any whole or partial copies of EDBA in any form, except those copies retained by Quest Softwares counsel
of record or experts retained under Section 9, in the possession, custody, or control of Quest Software or any of its employees, agents, or representatives, Quest Software must: (i) provide Computer Associates with prompt notice of such fact,
including the names of any individual who possessed the copy of EDBA or parts thereof; (ii) any use made of EDBA; and (iii) immediately return the copy of EDBA or any part thereof to Computer Associates.



e. Each Party represents that in executing this Agreement it is relying
solely on its own judgment, belief, and knowledge and upon the advice and recommendation of its counsel concerning the nature, extent, and duration of its rights and obligations deriving from this Agreement.



f. Each Party acknowledges that at no time has any individual or entity made
any representations, promises, or statements (whether oral or written) regarding the matters addressed herein to any other Party except as set forth in this Agreement. Each Party warrants and represents that it has not been induced to enter into
this Agreement on the basis of any other representations, promises, or statements (whether oral or written) made by any Party at any time.



g. Jenson represents and warrants to Computer Associates that she is making the payment in Section 4 from her personal funds.



11. Competitive products.



Except as expressly provided for in the License Agreement limiting Quest
Softwares rights regarding the Licensed Source Code for specific purposes, nothing in this Agreement or the License Agreement shall be interpreted as prohibiting or limiting in any way any Partys right to make, use, copy, distribute,
market, sell, or offer to sell any product competing directly or indirectly with any other Partys product. Nothing in this Agreement or the License Agreement shall be interpreted as prohibiting or limiting in any way a Partys right to
pursue against any other Party any claim it may have that is not released in this Agreement.



12. Waiver.



No waiver
of any term, provision, or condition of this Agreement, whether by conduct or otherwise, shall be deemed, or be construed, as a further or continuing waiver of any such term, provision or condition or as a waiver of any other term, provision, or
condition of this Agreement.



13. Interpretation.



This Agreement shall be interpreted simply and fairly and not strictly in
favor of or against any Party. To this end, the Parties agree that the terms and conditions of this Agreement are the product of an arms length negotiation. The Parties intend that each representation, warrant, and covenant contained herein
shall have independent significance. If any Party has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty, or covenant relating to the same subject matter
(regardless of the relative levels of specificity) that the Party has not breached shall not detract



9



---

from or mitigate the fact that the Party is in breach of the first representation, warranty, or covenant.

This Agreement shall be construed and governed in accordance with the laws of the State of Illinois, and with respect only

such Party may have to the laying of venue of any such dispute in that court. In the event the United States District Court for the Northern District of Illinois lacks or declines jurisdiction over any dispute relating to the enforcement and/or
interpretation of this Agreement then any such litigation shall be brought in the state court in Illinois, in the County of DuPage or Cook at the discretion of the Party initiating such litigation, and the Parties hereto expressly consent to the
jurisdiction of that court and waive any objection thereto.



16.
Injunction.



In the event that any Party is successful
either in proving the breach of this Agreement or in demonstrating a likelihood of prevailing in an action for breach of this Agreement, the Parties agree that monetary damages are inadequate compensation and that such Party is entitled to
injunctive relief.



17. Attorneys Fees.

under this Agreement, the party prevailing in the resolution of any such dispute, breach, or default shall be entitled to recover its reasonable attorneys fees and other costs incurred in connection with resolving such dispute, breach, or
default.
