7. What does this mean for me as an employee of Rubicon?

● We will continue to operate under the Rubicon name and there will be no meaningful changes to the team or how we do business.

● However, as we enter this new chapter, there are some rules we must all follow. There will be new reporting requirements, some restrictions on financial trading, and the SEC has strict guidelines governing external communications.

● Among other things, these restrictions concern disclosing what is known as “material, non-public information” (or “MNPI” – descriptions and examples below) to parties outside the company. Should this information be used as the basis upon which buying and selling of Rubicon stock is made, either by you or someone you know (commonly known as “Insider Trading”), there are civil and criminal penalties up to and including the termination of employment, fines, and prison.

● To avoid delays or any other repercussions the SEC might impose if we do not adhere to these rules, we must avoid speaking publicly about this process and our business metrics and financials.

● Accordingly, you must refrain from making statements about our company or our performance in open forums (e.g., online, to friends, on Facebook, Twitter, LinkedIn, via email, to existing or prospective customers, etc.). This means you cannot share or promote anything other than what Rubicon puts on our channels.

● Definition of MNPI: Information may be considered “material” if:

☐ a reasonable investor would consider it important in making a decision on whether to buy, sell, or hold Rubicon stock;

☐ a reasonable investor would view the information as significantly altering the total mix of information in the marketplace about the company; or

☐ the information could reasonably be expected to have a substantial effect on the price of Rubicon stock.

● Information is “non-public” until it is publicly disclosed:

☐ Published in such a way to provide broad, non-exclusionary distribution of information to the public; and

☐ Has been in the public domain for a sufficient period of time to be absorbed by the market and reflected in the price of the stock.

● Examples of MNPI:

☐ Financial or operating results

☐ Mergers, acquisitions, or joint ventures

☐ Business operations disruptions (e.g. leaks, hacks)

☐ Changes in senior management

☐ Current or pending litigation

8. What do I do if someone from outside Rubicon asks me about this transaction?

● If someone asks you about Rubicon’s plans to go public or its company fundamentals, the best response is to decline to answer and can say something like, “I can’t speak to that, but I would be happy to connect you with the appropriate team members.”

● Should you receive any press inquiries or questions from any other external parties, please forward details of the inquiry to Dan.Sampson@rubicon.com who can help handle media requests appropriately during this sensitive time.

9. How does this benefit me as an employee of Rubicon?

● Going public will unlock new and exciting opportunities for all of us, as well as provide new resources that will support our vision and mission.

● We hope our employees will take pride in our collective efforts as we kick off the next chapter in our journey to turn businesses into sustainable enterprises and neighborhoods into greener and smarter places to live and work and, ultimately, end waste.

10. Can I buy stock in Founder SPAC?

● You should not be buying or selling the SPAC stock (or encouraging others to do so) because you likely have material non-public information (MNPI) about Rubicon that the other party does not. Trading with MNPI is also referred to as “insider trading” and is illegal.

● MNPI may include information about Rubicon’s financial performance, the likelihood of being able to close on the business combination, new product/service offerings, developments regarding key suppliers or customers, etc.

● Trading while in possession of MNPI (either by you, or by someone at your recommendation or “tip”) could have serious consequences for you, including severe fines and jail sentences. It could also risk delaying or jeopardizing the transaction with Founder.

● If in doubt as to whether you have MNPI, don’t trade. Never provide MNPI to anyone outside of Rubicon.
