CONFIDENTIALITY, NON-INTERFERENCE, AND INVENTION ASSIGNMENT AGREEMENT

Exhibit 10.29

CONFIDENTIALITY, NON-INTERFERENCE, AND INVENTION ASSIGNMENT AGREEMENT

As a condition of my becoming employed by, or continuing employment with, Interactive Data Corporation, a Delaware corporation (the “Company”), and in consideration of my employment with the Company and my receipt of the compensation now and hereafter paid to me by the Company, I agree to the following:

Section 1. Confidential Information.

(a) Company Group Information. I acknowledge that, during the course of my employment, I will have access to information about the Company and its direct and indirect parents and subsidiaries (collectively, the “Company Group”) and that my employment with the Company shall bring me into close contact with confidential and proprietary information of the Company Group. In recognition of the foregoing, I agree, at all times during the term of my employment with the Company and for the ten (10) year period following my termination of my employment with the Company Group for any reason, to hold in confidence, and not to use, except for the benefit of the Company Group, or to disclose to any person, firm, corporation, or other entity without written authorization of the Company, any Confidential Information that I obtain or create. I further agree not to make copies of such Confidential Information except as authorized by the Company. I understand that “Confidential Information” means information that the Company Group has developed, acquired, created, compiled, discovered, or owned or will develop, acquire, create, compile, discover, or own, that has value in or to the business of the Company Group that is not generally known and that the Company wishes to maintain as confidential. I understand that Confidential Information includes, but is not limited to, any and all non-public information that relates to the actual or anticipated business and/or products, research, or development of the Company, or to the Company’s technical data, trade secrets, or know-how, including, but not limited to, research, product plans, or other information regarding the Company’s products or services and markets, customer lists, and customers (including, but not limited to, customers of the Company on whom I called or with whom I may become acquainted during the term of my employment), software, developments, inventions, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances, and other business information disclosed by the Company either directly or indirectly in writing, orally, or by drawings or inspection of premises, parts, equipment, or other Company property. Notwithstanding the foregoing, Confidential Information shall not include (i) any of the foregoing items that have become publicly known through no unauthorized disclosure by me or others who were under confidentiality obligations as to the item or items involved or (ii) any information that I am required to disclose to, or by, any governmental or judicial authority; provided, however, that in such event I will give the Company prompt written notice thereof so that the Company Group may seek an appropriate protective order and/or waive in writing compliance with the confidentiality provisions of this Confidentiality, Non-Interference, and Invention Assignment Agreement (the “Non-Interference Agreement”).

(b) Former Employer Information. I represent that my performance of all of the terms of this Non-Interference Agreement as an employee of the Company has not breached and will not breach any agreement to keep in confidence proprietary information,

knowledge, or data acquired by me in confidence or trust prior or subsequent to the commencement of my employment with the Company, and I will not disclose to any member of the Company Group, or induce any member of the Company Group to use, any developments, or confidential or proprietary information or material I may have obtained in connection with employment with any prior employer in violation of a confidentiality agreement, nondisclosure agreement, or similar agreement with such prior employer.

Section 2. Developments.

(a) Developments Retained and Licensed. I have attached hereto, as Schedule A, a list describing with particularity all developments, original works of authorship, developments, improvements, and trade secrets that I can demonstrate were created or owned by me prior to the commencement of my employment (collectively referred to as “Prior Developments”), which belong solely to me or belong to me jointly with another, that relate in any way to any of the actual or proposed businesses, products, or research and development of any member of the Company Group, and that are not assigned to the Company hereunder, or if no such list is attached, I represent that there are no such Prior Developments. If, during any period during which I perform or performed services for the Company Group both before or after the date hereof (the “Assignment Period”), whether as an officer, employee, director, independent contractor, consultant, or agent, or in any other capacity, I incorporate (or have incorporated) into a Company Group product or process a Prior Development owned by me or in which I have an interest, I hereby grant the Company, and the Company Group shall have, a non-exclusive, royalty-free, irrevocable, perpetual, transferable worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell, and otherwise distribute such Prior Development as part of or in connection with such product or process.

(b) Assignment of Developments. I agree that I will, without additional compensation, promptly make full written disclosure to the Company, and will hold in trust for the sole right and benefit of the Company all developments, original works of authorship, inventions, concepts, know-how, improvements, trade secrets, and similar proprietary rights, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or have solely or jointly conceived or developed or reduced to practice, or have caused or may cause to be conceived or developed or reduced to practice, during the Assignment Period, whether or not during regular working hours, provided they either (i) relate at the time of conception, development or reduction to practice to the business of any member of the Company Group, or the actual or anticipated research or development of any member of the Company Group; (ii) result from or relate to any work performed for any member of the Company Group; or (iii) are developed through the use of equipment, supplies, or facilities of any member of the Company Group, or any Confidential Information, or in consultation with personnel of any member of the Company Group (collectively referred to as “Developments”). I further acknowledge that all Developments made by me (solely or jointly with others) within the scope of and during the Assignment Period are “works made for hire” (to the greatest extent permitted by applicable law) for which I am, in part, compensated by my salary, unless regulated otherwise by law, but that, in the event any such Development is deemed not to be a work made for hire, I hereby assign to the Company, or its designee, all my right, title, and interest throughout the world in and to any such Development.

(c) Maintenance of Records. I agree to keep and maintain adequate and current written records of all Developments made by me (solely or jointly with others) during the Assignment Period. The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, and any other format. The records will be available to and remain the sole property of the Company Group at all times. I agree not to remove such records from the Company’s place of business except as expressly permitted by Company Group policy, which may, from time to time, be revised at the sole election of the Company Group for the purpose of furthering the business of the Company Group.

(d) Intellectual Property Rights. I agree to assist the Company, or its designee, at the Company’s expense, in every way to secure the rights of the Company Group in the Developments and any copyrights, patents, trademarks, service marks, database rights, domain names, mask work rights, moral rights, and other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments that the Company shall deem necessary in order to apply for, obtain, maintain, and transfer such rights and in order to assign and convey to the Company Group the sole and exclusive right, title, and interest in and to such Developments, and any intellectual property and other proprietary rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the termination of the Assignment Period until the expiration of the last such intellectual property right to expire in any country of the world; provided, however, the Company shall reimburse me for my reasonable expenses incurred in connection with carrying out the foregoing obligation. If the Company is unable because of my mental or physical incapacity or unavailability for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Developments or original works of authorship assigned to the Company as above, then I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact to act for and in my behalf and stead to execute and file any such applications or records and to do all other lawfully permitted acts to further the application for, prosecution, issuance, maintenance, and transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company any and all claims, of any nature whatsoever, that I now or hereafter have for past, present, or future infringement of any and all proprietary rights assigned to the Company.

Section 3. Returning Company Group Documents.

I agree that, at the time of termination of my employment with the Company for any reason, I will deliver to the Company (and will not keep in my possession, recreate, or deliver to anyone else) any and all Confidential Information and all other documents, materials, information, and property developed by me pursuant to my employment or otherwise belonging to the Company. I agree further that any property situated on the Company’s premises and owned by the Company (or any other member of the Company Group), including disks and other storage media, filing cabinets, and other work areas, is subject to inspection by personnel of any member of the Company Group at any time with or without notice.

Section 4. Disclosure of Agreement.

As long as it remains in effect, I will disclose the existence of this Non-Interference Agreement to any prospective employer, partner, co-venturer, investor, or lender prior to entering into an employment, partnership, or other business relationship with such person or entity.

Section 5. Restrictions on Interfering.

(a) Non-Competition. During the period of my employment with the Company (the “Employment Period”) and the Post-Termination Restricted Period, I shall not, directly or indirectly, individually or on behalf of any person, company, enterprise, or entity, or as a sole proprietor, partner, stockholder, director, officer, principal, agent, or executive, or in any other capacity or relationship, engage in any Competitive Activities within any State of the United States of America and any other jurisdiction in which any member of the Company Group engages (or has committed plans to engage) in business during the Employment Period, or during the Post-Termination Restricted Period was engaged in business (or had committed plans to engage of which I have knowledge at the time of termination of my employment); provided, that my indirect ownership (i.e., ownership through a fund that is not controlled by me or any of my affiliates) of not more than three percent (3%) of the outstanding shares of any publicly traded company shall not be deemed to breach of this Section 5(a).

(b) Non-Interference. During the Employment Period and the Post-Termination Restricted Period, I shall not, directly or indirectly for my own account or for the account of any other individual or entity, engage in Interfering Activities.

(c) Definitions. For purposes of this Non-Interference Agreement:

(i) “Business Relation” shall mean any current or prospective client, customer, licensee, or other business relation of the Company Group, or any such relation that was a client, customer, licensee, supplier, or other business relation within the six (6) month period prior to the expiration of the Employment Period, in each case, to whom I provided services, or with whom I transacted business, or whose identity became known to me in connection with my relationship with or employment by the Company.

(ii) “Competitive Activities” shall mean any business activities in which any member of the Company Group is engaged (or has committed plans to engage) during the Employment Period.

(iii) “Interfering Activities” shall mean (A) encouraging, soliciting, or inducing, or in any manner attempting to encourage, solicit, or induce, any individual or entity employed by, or providing consulting services to, any member of the Company Group to terminate such individual’s or entity’s employment or services (or in the case of a consultant, materially reducing such services) with the Company Group;

(B) hiring any individual who was employed by any member of the Company Group within the six (6) month period prior to the date of such hiring; or (C) encouraging, soliciting, or inducing, or in any manner attempting to encourage, solicit, or induce, any Business Relation to cease doing business with or reduce the amount of business conducted with the Company Group, or in any way interfering with the relationship between any such Business Relation and the Company Group.

(iv) “Post-Termination Restricted Period” shall mean the period commencing on the date of the termination of the Employment Period for any reason and ending on the twelve (12) month anniversary of such date of termination.

(d) Non-Disparagement. I agree that during the Employment Period, and at all times thereafter, I will not make any disparaging or defamatory comments regarding (i) any member of the Company Group or its respective current or former directors, officers, or employees, or (ii) my relationship with any member of the Company Group, or (iii) any conduct or events which precipitated any termination of my employment from any member of the Company Group. Similarly, the Company shall instruct its executive officers and directors to refrain from making any disparaging or defamatory comments regarding (i) me in any respect, or (ii) my relationship with any member of the Company Group, or (iii) the conduct or events that precipitated my termination of employment from any member of the Company Group (it being understood that the foregoing shall not prevent any representative of the Company Group from verifying my employment to any potential subsequent employer). However, the obligations under this subparagraph (d) shall not apply to disclosures required by applicable law, regulation, or order of a court or governmental agency.

(e) Consideration. I agree that as additional consideration for my compliance with the terms and conditions of this Non-Interference Agreement, upon the termination of employment for any reason other than by the Company for Cause (as defined in my Employment Agreement, dated November 4, 2010, with the Company (the “Employment Agreement”)), the Company shall pay me $200,000 (the “Non-Interference Consideration”), payable in substantially equal monthly installments during the Post-Termination Restricted Period. The Non-Interference Consideration shall be in addition to any severance benefits that I may receive upon a termination of my employment under the terms of my Employment Agreement, and I acknowledge and agree that the payment of the Non-Interference Consideration shall be subject to my execution, delivery to the Company, and non-revocation of the Release of Claims (as defined in the Employment Agreement) in accordance with the provisions of Section 8(h) of the Employment Agreement. I agree further that the payment of the Non-Interference Consideration shall, subject to delivery of written notice from the Company and an opportunity to address the Company’s Board of Directors within five (5) business days following receipt of such notice, immediately cease if I am in breach of any provision of this Non-Interference Agreement.

(f) Other Restrictions. The covenants contained in this Section 5 are in addition to, and not in lieu of, any similar covenants to which Employee may be subject from time to time.

Section 6. Reasonableness of Restrictions.

I acknowledge and recognize the highly competitive nature of the Company’s business, that access to Confidential Information renders me special and unique within the Company’s industry, and that I will have the opportunity to develop substantial relationships with existing and prospective clients, accounts, customers, consultants, contractors, investors, and strategic partners of the Company Group during the course of and as a result of my employment with the Company. In light of the foregoing, I recognize and acknowledge that the restrictions and limitations set forth in this Non-Interference Agreement are reasonable and valid in geographical and temporal scope and in all other respects and are essential to protect the value of the business and assets of the Company Group. I acknowledge further that the restrictions and limitations set forth in this Non-Interference Agreement will not materially interfere with my ability to earn a living following the termination of my employment with the Company and that my ability to earn a livelihood without violating such restrictions is a material condition to my employment with the Company.

Section 7. Independence; Severability; Blue Pencil.

Each of the rights enumerated in this Non-Interference Agreement shall be independent of the others and shall be in addition to and not in lieu of any other rights and remedies available to the Company Group at law or in equity. If any of the provisions of this Non-Interference Agreement or any part of any of them is hereafter construed or adjudicated to be invalid or unenforceable, the same shall not affect the remainder of this Non-Interference Agreement, which shall be given full effect without regard to the invalid portions. If any of the covenants contained herein are held to be invalid or unenforceable because of the duration of such provisions or the area or scope covered thereby, I agree that the court making such determination shall have the power to reduce the duration, scope, and/or area of such provision to the maximum and/or broadest duration, scope, and/or area permissible by law, and in its reduced form said provision shall then be enforceable.

Section 8. Injunctive Relief.

I expressly acknowledge that any breach or threatened breach of any of the terms and/or conditions set forth in this Non-Interference Agreement may result in substantial, continuing, and irreparable injury to the members of the Company Group. Therefore, I hereby agree that, in addition to any other remedy that may be available to the Company, any member of the Company Group shall be entitled to seek injunctive relief (but not on an ex parte basis), specific performance, or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this Non-Interference Agreement without the necessity of proving irreparable harm or injury as a result of such breach or threatened breach. Notwithstanding any other provision to the contrary, I acknowledge and agree that the Post-Termination Restricted Period shall be tolled during any period of violation of any of the covenants in Section 5 hereof and during any other period required for litigation during which the Company or any other member of the Company Group seeks to enforce such covenants against me if it is ultimately determined that I was in breach of such covenants.

Section 9. Cooperation.

I agree that, following any termination of my employment, I will continue to provide reasonable cooperation to the Company and/or any other member of the Company Group and its or their respective counsel in connection with any investigation, administrative proceeding, or litigation relating to any matter that occurred during my employment in which I was involved or of which I have knowledge. As a condition of such cooperation, the Company shall reimburse me for reasonable out-of-pocket expenses incurred at the request of the Company with respect to my compliance with this paragraph, and I shall be entitled to indemnification in accordance with the terms of Section 5(b) of my employment agreement with the Company. I also agree that, in the event that I am subpoenaed by any person or entity (including, but not limited to, any government agency) to give testimony or provide documents (in a deposition, court proceeding, or otherwise) that in any way relates to my employment by the Company and/or any other member of the Company Group, I will give prompt notice of such request to the Company and will make no disclosure until the Company and/or the other member of the Company Group has had a reasonable opportunity to contest the right of the requesting person or entity to such disclosure.
