Exhibit 10.29

MASTER SERVICES AGREEMENT

THIS MASTER SERVICES AGREEMENT (“Agreement”) is made as of 29 June 2010 (“Effective Date”), between United BioSource Corporation with a place of business at 3822 Summit, Kansas City, Missouri 64111 (“UBC”) and Corcept Therapeutics Incorporated with its office located at 149 Commonwealth Drive, Menlo Park, CA 94025 (“Client”), with each of UBC and Client being referred to herein individually as a “Party” or collectively as the “Parties”.

WHEREAS, UBC is engaged in the business of providing its clients with specialized pharmaceutical services in connection with the design, management and conduct of clinical trials and registries of pharmaceuticals and biologics, and employs personnel knowledgeable about and experienced in clinical research, statistics, computer programming, contracting, data processing and management, project management, and drug development regulations (United States and international) (the “Services”); and

WHEREAS, Client wishes to retain UBC on an as-needed basis to provide Risk Evaluation and Mitigation Services (REMS) services (“Projects”).

NOW, THEREFORE, In consideration of the premises and of the mutual promises of each Party to the other herein contained, it is hereby mutually agreed as follows:

1. Services

1.1 The Services to be performed hereunder and accompanying timelines, budget and payment terms shall be specified in separate Statements of Work (“SOWs”), which upon signature and execution by both Parties, shall be deemed incorporated herein. Each SOW shall constitute a separate agreement and shall stand alone with respect to any other SOW entered into under this Agreement. In the event of a conflict between this Agreement and any SOW, the provisions of this Agreement will control, unless the SOW specifically acknowledges the conflict and expressly states that the conflicting SOW controls.

1.2 Any changes to the Services shall be subject to mutual agreement by the Parties and the details of such changes (e.g. budget impact, scope of services changes, etc.) shall be agreed upon and memorialized via an amendment to the applicable SOW.

1.3 UBC shall not subcontract or assign any Services to a non-affiliate without the prior written consent of Client provided, however, that UBC’s use of subcontractors is deemed approved when UBC’s proposal for Services explicitly details the usage of subcontractors or affiliate and such proposal has been accepted by Client. Should any subcontract or assignment of the Services occur, UBC shall be solely responsible for ensuring that any subcontractors or assignees are in compliance with the terms of this Agreement.

2. Compensation

2.1 Compensation for the Services rendered pursuant to this Agreement shall be in accordance with the applicable SOW. All payments (excluding Disputed Amounts as defined below) are due within thirty (30) days after receipt of invoice.

dispute may concern not only the accuracy of the charge itself, but also any claim of [ *** ] that relates to the specific charges in the invoice. A Disputed Amount raised by Client in writing within such [ *** ] day period may be withheld from the specific invoice to which it relates. All Disputed Amounts that Client subsequently agrees in writing to pay or that are required to be paid pursuant to a proper court order or award shall be paid within [ *** ] days from the date of such agreement or determination.

2.2 Unless otherwise indicated in the respective SOW, all budgets, invoices and payments, and SOWs under this Agreement will be in United States Dollars (“US$”).

2.4 In the event delay, postponement or suspension in the Services is requested by Client, and such delay, postponement or suspension has been continuing for [ *** ] days, Client shall pay UBC for all Services rendered through the date of such delay, postponement or suspension plus reasonable costs directly arising out of such delay, postponement or suspension, if any. Upon notice of delay, postponement or suspension of the Services, UBC agrees to use its commercially reasonable efforts to immediately curtail its efforts and make no subsequent commitments for expenditures under this Agreement. In the event of resumption of the Project, Client shall notify UBC, at which time UBC will resume Services under the terms of this Agreement.

2.5 In the event the Services being performed under any SOW are terminated pursuant to Section 7 below, unless such termination is due to UBC’s breach of any term or obligation hereunder, or other termination for cause, UBC shall be (a) compensated within [ *** ] days of termination for all fees and actual documented permitted costs incurred by UBC due as of the date of termination but not yet paid pursuant to the applicable SOW and (b) reimbursed any and all reasonable uncancellable obligations regarding third parties that were incurred as of the date of termination in compliance with the applicable SOW. Any funds held by UBC which shall be shown by Client to be unearned at the date of termination shall be returned to Client within [ *** ] days of termination of this Agreement.

3. Confidential Information

3.1 Both Parties shall treat any business strategies, plans and procedures, proprietary information, scientific, medical and technical data and trade secrets, and other confidential information and materials of the other Party, whether written, electronic, visual or verbal, tangible or intangible, made available, disclosed, or otherwise made known to it (“Confidential Information”) as the confidential and exclusive property of the other Party and shall not divulge or disclose the same to third parties except with the prior written consent of the other Party.

the other Party only for purposes of performing its obligations under this Agreement, and neither Party will use such Confidential Information for any other purpose without the prior written consent of the other Party. The provisions of this Section shall not apply to information which: a) is in, or later comes into, the public domain other than by breach of this Agreement or other fault of receiving Party; b) the receiving Party can demonstrate was in its possession prior to receipt of the Confidential Information as evidenced by its written business records; c) is independently received by receiving Party from a third-party with the legal right to disclose it on a non-confidential basis; d) is independently developed by receiving Party without reliance on or use of the Confidential Information of the disclosing Party, as evidenced by receiving Party’s written business records; or e) is required to be disclosed by a court of competent jurisdiction, by any governmental agency having supervisory authority over the business of the disclosing Party, or by any administrative body or legislative body (including a committee thereof) with jurisdiction to order receiving Party to divulge, disclose or make accessible such information; provided that, in the event that receiving Party is ordered by a court or other government agency to disclose any Confidential Information, receiving Party shall (i) promptly notify disclosing Party of such order, (ii) at the written request of disclosing Party, diligently contest such order at the sole expense of disclosing Party as expenses occur, and (iii) at the written request of disclosing Party, seek to obtain at the sole expense of disclosing Party such confidential treatment as may be available under applicable laws for any information disclosed under such order.

The foregoing notwithstanding, each Party may retain one (1) archival copy of the Confidential Information provided by the other Party in a limited access file for purposes of monitoring its ongoing obligations hereunder and to comply with any applicable regulatory requirements (including, but not limited to, those set forth in ICH Guideline E6GCP § 4.9.5 and 21 CFR Section 312.57).

3.5 Each Party agrees that a breach of this Agreement by the receiving Party may result in irreparable harm to disclosing Party for which money damages would be inadequate.
