This filing relates to the proposed business combination between Inspirato LLC (“Inspirato”) and Thayer Ventures Acquisition Corporation (“Thayer”) pursuant to the terms of that certain Business Combination Agreement, dated as of June 30, 2021 (the “Business Combination Agreement”).

Good Morning INSPIRATO –

First, it is exciting to write to all of you! I know many of you have been wondering why my typically frequent SKIMS have taken a bit of a backseat over the past few months. To say that things have been busy would be quite an understatement. Thankfully, one reason for this is that our subscribers and members continue to love traveling with us. I can’t remember a time when more was happening – it is all very exciting. We will be sharing much more about how we have been performing as well as some exciting business innovations in the coming weeks/months.

Today though, I am writing to tell you about a milestone. Early today, Thayer Ventures Acquisition Corp. officially filed an S-4 Registration Statement with the Securities and Exchange Commission (SEC) in connection with its business combination with INSPIRATO. This is the next step in our process to becoming a public company. Rather than me rambling about it here, our team has created an internal FAQ that accompanies this email. We are committed to keeping you updated and informed and recommend that you review the FAQ. As always, please let us know if you have additional questions.

There have been a number of people who have quite literally worked around the clock to accomplish this filing. It is always hard to just call out a name or two as we inevitably leave out others that have been involved, but please know that we are blessed with an incredible team of professionals that have gone way above and beyond. I can’t wait for the world to return to “normal”, for our office to be filled again, and for us to have an All-Employee Meeting where we can properly recognize each of these individuals.

In addition to the FAQ about our filing, I’ve also attached an overview of our 2022 Employee Compensation program. This document does a good job of giving a broad overview of our compensation philosophies and the components of compensation we have in mind for 2022 and beyond. We know that many of you will have questions and all of you will want to know how becoming a public company will impact you and your compensation personally. Trust that we understand this and are committed to having specific discussions with everyone – when appropriate. There are legal and regulatory considerations around the timing of these discussion, but again, trust that we will address all of your questions in the coming months.

One more important thing to note – we realize that the impacts of COVID are still creating an air of uncertainty—especially around coming back to the office and resuming fully normal operations. We remain committed to putting your and your families’ safety first and will continue to keep you informed. Until then – enjoy the change in season with friends and family, travel safely and thank you for ALL that each of you do to make INSPIRATO the great company that it is! I look forward to seeing all of you soon.

2022 Inspirato Employee Compensation Program

Initial Overview

This document is an initial overview of our approach to the 2022 Inspirato Employee Compensation Program (“Compensation Program”) and an update on our current Compensation Program for full-time year-round Inspirato employees. As Inspirato evolves from a private entity to a publicly traded company, the Compensation Program will continue to evolve as well. As part of this evolution, it will be important to connect employee compensation more directly to value creation for our stockholders. To help guide us toward this objective, we have been working with outside compensation experts to understand best practices and market standards used by top public companies. Ultimately, our goal is to recruit and retain incredible talent to help us build value and realize our mission here at Inspirato.

While this overview provides details on our current plans, it is subject to change. And to state the obvious here at the outset, nothing in this overview should be taken to create or imply the existence of an employment contract, or alter the “at-will” relationship between any employee and the company.

Our Compensation Philosophy

Inspirato’s compensation philosophy is designed to align with our business strategy by rewarding contributions that support our vision, mission, and values.

Four core beliefs serve as the foundation of our philosophy. We believe in:

Compensation Components

At Inspirato, compensation is a combination of three components: 1) base salary, 2) short-term incentives such as cash bonuses and commission plans, and 3) long-term incentive awards such as equity-based awards. Certain positions will be eligible to receive tips as part of their compensation which are also considered as a part of total compensation. In support of our compensation philosophy, each component is based on external local market analyses, internal equity analyses, and individual and company performance. And each component is evaluated regularly, including an annual compensation review cycle of all three.

Base Salary

As part of Inspirato’s annual compensation review process, eligible employees will be reviewed for a salary adjustment. Salary adjustments are based primarily on external local market analyses as well as individual performance and are implemented in accordance with local laws and regulations.

Cash Bonuses

Despite the ongoing effects of COVID on our business, we expect to make a partial bonus payout to bonus eligible employees for 2021 performance, which we expect to pay in February 2022. We also anticipate discretionary bonuses being part of our 2022 compensation program. Bonuses will be determined as a percentage of base salary, based on each eligible employee’s level.

All bonuses are subject to review and approval by Inspirato’s Board of Directors. Discretionary bonuses, including the size and terms, are at the company’s sole and total discretion, and are only earned by eligible employees who remain continuously employed through the applicable payment date.

Commission Plans

For eligible employees, we expect existing commission plans to remain in place for 2021. New commission plans will be communicated at the beginning of 2022.

New Equity-Based Awards

As we transition to a publicly traded company, it’s more vital than ever to connect employee compensation more directly to value creation for our stockholders through grants of equity-based awards. These awards allow all full-time year-round employees to benefit directly from the success of the company. Historically, these awards have been in the form of options to purchase units of Inspirato. However, after Inspirato becomes a publicly traded company, these awards will typically be issued in the form of restricted stock units (“RSUs”) settleable in shares of Inspirato’s common stock, subject to the terms and conditions of Inspirato’s 2021 Equity Incentive Plan and a restricted stock unit award agreement.

As part of the annual compensation review process, employees will be eligible to receive equity-based awards in the form of RSUs. The size of an award of RSUs will be based on the employee’s level, individual contribution, and company performance.

Equity-based awards for the 2022 fiscal year will be issued in the first quarter of 2022. All equity-based awards, including the applicable terms and conditions, are subject to review and approval by Inspirato’s Board of Directors. Equity-based awards, including the size and terms of the awards, are in the sole and total discretion of the Company.

In addition, we are creating an Employee Stock Purchase Plan (ESPP) as another way for employees to share in the success of the company. Employees will be allowed to elect a portion of their salary through payroll deductions to purchase company equity through the plan. Due to regulatory requirements, the plan will not be launched until at least 60 days after our stock is publicly traded. We will provide more details about the plan at that time.

As part of transitioning to a publicly traded company, Inspirato is working towards launching a new online solution for our overall employee equity program. We expect this new solution to allow employees to view the real-time value of their equity-based awards and such awards’ vesting schedules, and to make transactions with respect to shares obtained from equity-based awards.

Compensation Program Communication

Employees will be provided with additional details about the 2022 annual compensation review process during the first quarter of 2022, with the objective of communicating their 2022 base salary, 2021 cash bonus, if any, 2022 commission plan, if applicable, and 2022 equity-based award, if applicable.

During the first quarter of 2022, we will also communicate with individuals who were previously granted options to purchase Inspirato units (“Inspirato Options”), to share information about how our transition to a publicly traded company impacts them.

Forward-Looking Statements

This document may contain a number of “forward-looking statements.” Forward-looking statements include information concerning Thayer’s or Inspirato’s possible or assumed future results of operations, business strategies, debt levels, competitive position, industry environment, potential growth opportunities and the effects of regulation, including whether this proposed business combination will generate returns for shareholders. These forward-looking statements are based on Thayer’s or Inspirato’s management’s current expectations, estimates, projections and beliefs, as well as a number of assumptions concerning future events. When used in this document, the words “estimates,” “projected,” “expects,” “anticipates,” “forecasts,” “plans,” “intends,” “believes,” “seeks,” “may,” “will,” “should,” “future,” “propose” and variations of these words or similar expressions (or the negative versions of such words or expressions) are intended to identify forward-looking statements.

These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside Thayer’s or Inspirato’s management’s control, that could cause actual results to differ materially from the results discussed in the forward-looking statements. These risks, uncertainties, assumptions and other important factors include, but are not limited to: (a) the occurrence of any event, change or other circumstances that could give rise to the termination of the Business Combination Agreement and the proposed business combination contemplated thereby; (b) the inability to complete the proposed business combination due to the failure to obtain approval of the shareholders of Thayer or other conditions to closing in the Business Combination Agreement; (c) the ability to meet Nasdaq’s listing standards following the consummation of the proposed business combination; (d) the inability to complete the private placement into Thayer; (e) the risk that the proposed business combination disrupts current plans and operations of Inspirato or its subsidiaries as a result of the announcement and consummation of the transactions described herein; (f) the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (g) costs related to the proposed business combination; (h) changes in applicable laws or regulations, including legal or regulatory developments (such as the U.S. Securities and Exchange Commission’s (the “SEC”) recently released statement on accounting and reporting considerations for warrants in special purpose acquisition companies (“SPACs”)) which could result in the need for Thayer to restate its historical financial statements and cause unforeseen delays in the timing of the business combination and negatively impact the trading price of Thayer’s securities and the attractiveness of the business combination to investors; (i) the possibility that Inspirato may be adversely affected by other economic, business and/or competitive factors; (j) the ability to implement business plans, forecasts, and other expectations after the completion of the proposed transaction, and identify and realize additional opportunities; (k) the risk of downturns in the travel and hospitality industry, including residual effects of the COVID-19 pandemic; and (l) costs related to the transaction and the failure to realize anticipated benefits of the transaction or to realize estimated pro forma results and underlying assumptions, including with respect to estimated shareholder redemptions. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of the registration statement on Form S-4 referenced above and discussed below and other documents filed by Thayer from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. You are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made.

Except as required by law, neither Thayer nor Inspirato undertakes any obligation to update or revise its forward-looking statements to reflect events or circumstances after the date of this release. Additional risks and uncertainties are identified and discussed in Thayer’s reports filed with the SEC and available at the SEC’s website at www.sec.gov.
