Other Commitments

On July 25, 2016, we entered into a Loan and Security Agreement (the "Loan Agreement") with SmileDirectClub, LLC ("SDC") where we agreed to provide a loan of up to $15.0 million in one or more advances to SDC (the "Loan Facility"). On July 24, 2017, we amended the Loan Agreement with SDC to increase the line of credit up to $30.0 million. Available advances under the Loan Facility are subject to a borrowing base of 80% of SDC's eligible accounts receivable, determined in accordance with the terms of the Loan Agreement, and the satisfaction of other customary conditions. The advances bear interest, paid quarterly, at the rate of 7% per annum. Advances that are repaid or prepaid may be reborrowed. All outstanding principal and accrued and unpaid interest on the advances are due and payable on July 25, 2021. SDC's obligations in respect of the Loan Agreement are collateralized by a security interest in substantially all of SDC's assets. As of June 30, 2017, $15.0 million of advances under the Loan Facility were issued and outstanding (Refer to Note 4 "Equity Method Investments" of the Notes to Condensed Consolidated Financial Statements for more information on our investments in SDC).

We have entered into certain investments with a privately held company where we have committed to purchase up to $5.0 million in convertible promissory notes. The first convertible promissory note was issued on July 14, 2016 for $2.0 million and a second convertible promissory note was issued on June 5, 2017 for $2.0 million. Both notes are outstanding as of June 30, 2017. The remaining $1.0 million available is conditioned upon achievement of various business milestones. The notes all mature on December 30, 2018 and accrue interest annually at 2.5%.

On June 30, 2017, we entered into a non-cancelable Addendum to the Master Subscription Agreement with a software company to renew our software license subscription for the total price of $50.0 million over the next three years starting on January 1, 2018.

On July 24, 2017, we entered into a Purchase and Sale Agreement (the "Purchase Agreement") with Belen Business Center CR, S.A. ("Seller") to purchase the building located in the Republic of Costa Rica (the "Property") for a purchase price of $26.1 million. On July 28, 2017, $5.2 million was deposited into escrow. We have a right to inspect the Property until August 15, 2017 ("Due Diligence Period") and if we decide to terminate the Purchase Agreement during the Due Diligence Period, the deposit will be refunded to us in full.

Off-Balance Sheet Arrangements

As of June 30, 2017, we had no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources.

Indemnification Provisions

In the normal course of business to facilitate transactions in our services and products, we indemnify certain parties: customers, vendors, lessors and other parties with respect to certain matters, including, but not limited to, services to be provided by us and intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and our executive officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. Several of these agreements limit the time within which an indemnification claim can be made and the amount of the claim.

It is not possible to make a reasonable estimate of the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Additionally, we have a limited history of prior indemnification claims and the payments we have made under such agreements have not had a material adverse effect on our results of operations, cash flows, or financial position. However, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our results of operations or cash flows in a particular period. As of June 30, 2017, we did not have any material indemnification claims that were probable or reasonably possible.
