Exhibit 10.21

SAVVIS MASTER SERVICES AGREEMENT

THIS MASTER SERVICES AGREEMENT (“MSA”) is by and between SAVVIS Communications Corporation and its affiliates (“SAVVIS”) and Visto Corporation d/b/a Good Technology (“Customer”) and is entered into as of this 29th day of May, 2009 (“Effective Date”).

1. Services. SAVVIS will provide the Services in accordance with the Agreement. The “Agreement” means this MSA plus all applicable Service Schedules, SAVVIS Service Guides, Service Orders, service level agreements (“SLAs”) and any other documents that are expressly incorporated herein (collectively “Service Attachments”). [**]. Any requests for ancillary services not described in the applicable Service Attachments may be provided on an individual case basis as agreed to in writing by the parties.

2. Term. The term of the Agreement will commence on the Effective Date and continue until the expiration of [**], unless earlier terminated in accordance with the Agreement (“Term”).

3. Payment. All payments are due in full within [**] after the date of the invoice (“Due Date”). In addition to the Service charges, Customer shall also pay all applicable Taxes [**]. Any amount not received by the Due Date will be past due [**]. Billing for each Service shall commence on the “Billing Commencement Date”, as defined in the applicable Service Schedule. [**]. SAVVIS may, upon 30 days prior notice, modify the payment terms or require a mutually acceptable form of security (e.g., a deposit) if Customer has repeatedly failed to pay its invoices by the Due Date or if there has been a material, adverse change in its financial condition. Notwithstanding any other provision to the contrary and not more than once per calendar year, SAVVIS may increase the charges applicable to any Service provided hereunder in an amount not to exceed the latest annual increase in the Consumer Price Index, specifically, the U.S. Department of Labor, Bureau of Labor Statistics “All Items Consumer Price Index for All Urban Consumers (CPI-U) for the U.S. City Average”. Such increase shall be effective upon the date set forth in SAVVIS’ written notice thereof to Customer. The foregoing shall not limit SAVVIS’ ability to increase charges: (i) as set forth in a Service Schedule; or (ii) during any automatic renewal term.

4. Customer Obligations. All use of SAVVIS’ network and the Services by Customer and its End Users will comply with the AUP, which is incorporated herein by reference. SAVVIS may make reasonable changes to the AUP at any time and such change will be effective upon posting to SAVVIS’ website or other notice to Customer. SAVVIS may suspend the Services or otherwise restrict access to the SAVVIS network without notice if SAVVIS learns of an AUP violation that, in its reasonable discretion, is unlawful or is likely to cause loss or liability for SAVVIS or any other party. Any such suspension or restriction will be on the most limited basis as SAVVIS determines is reasonably practical under the circumstances in order to address the underlying violation. [**].

5. Termination. Customer may terminate the Agreement upon [**] notice in the event of a material breach of the Agreement by SAVVIS, if such breach is not cured within that period. SAVVIS may suspend Service or terminate the Agreement: (a) upon [**] or any payment default, if such default is not cured within that period; (b) [**]; or (c) upon [**] notice in the event of any other material breach of the Agreement by Customer, if such breach is not cured within that period (unless a different notice period expressly set forth in the Agreement applies). If Customer terminates an ordered Service prior to its delivery, cancellation fees will apply as set forth in the Service Schedule. If, after the delivery of Service but prior to the conclusion of the applicable Service term, the Service or this Agreement is terminated either by SAVVIS for cause or by Customer for any reason other than cause, then Customer shall be liable for: [**]. The parties agree that any cancellation fees and early termination charges set forth in the Agreement constitute liquidated damages and are not intended as a penalty. If a particular Service is terminated by Customer without cause or by SAVVIS for cause, and SAVVIS advises the Customer in writing that in SAVVIS’ good faith judgment provision of a related Service is impractical or impossible (“Related Service”) as a result of such termination, then the Related Service shall be deemed terminated for cause by SAVVIS and any applicable termination charges will apply.
