Delaware has the most developed corporate law and support services for corporate transactions (you can file charters, mergers, etc. within an hour there; good luck doing that in most other states, including CA). Every company that incorporates in Delaware adds further value to every other company that's in Delaware. Each marginal company adds to the Delaware legal corpus and support structure because (1) it ensures Delaware has the greatest variety and largest supply of potentially significant corporate legal cases, which means it has the greatest variety and largest supply of actually adjudicated cases and thus developed and stable law, and (2) it pays Delaware annual fees for those support services. This in turn attracts more companies to incorporate there because of that ever expanding corpus/infrastructure. And so on and so forth.
The term sheet we posted is just meant to show what a pretty good term sheet looks like from a good investor. The investor having its legal fees reimbursed by the company is something that shows up all the time. Sure, you can negotiate that if you want. You can negotiate other things too, or choose not to. The way this usually plays out though is that unless you have the kind of leverage that lets you basically write your own term sheet, you have to prioritize, and most people prioritize getting what they want on valuation, control, clean terms, etc. before making sure to shift $30K in legal fees back to the investor.
Some amount of re-vesting is often required at Series A, but it largely has to do with how vested the founders already are. If for example they've been working on the company for only a year, the existing vesting schedule will probably be left alone. On the other hand, if they've been working on the company for multiple years and are close to fully vested at Series A, it's almost guaranteed that the Series A investor will ask the founder to re-vest some amount of shares (for the reason you describe).
Re-vesting generally does not show up again after the Series A.
If you get fired before you fully vest, whether you leave with the equity you have or all your equity is something you can negotiate as part of the vesting terms.
In practice, the firms that give 1-pagers don't really try to pull a bait and switch like that. They offer the 1-pager so they can close quickly, not so they can get quickly into the no shop to drive onerous terms. Could a firm consciously adopt that strategy? Sure, but it wouldn't last very long because people talk to each other.
Also, even the 1-pager goes into detail on liquidation preference, veto rights, board composition, drag-along and founder vesting. These are the items that get negotiated a lot or are otherwise really important to know before signing up.
As mentioned elsewhere, this exercise was descriptive, not prescriptive. Some of the founder friendliest investors use term sheets that look similar to this. Some of the unfriendliest investors still send 10 page term sheets.
Major investors concept (investor has to have invested at least $X) is often added in the definitives. Longer term sheets just state a threshold dollar amount; shorter ones (like this one) just skip that definition and just add it in the definitives.
I'm no fan of long term sheets, but IMO, this term sheet doesn't just punt that term to definitives; it gives me the expectation that all investors will receive "major investor" rights without dollar or ownership thresholds. Specifically, I feel that way because the "major investor" rights (ROFR, co-sale, pro-rata, info) are are in-line with anti-dilution and registration rights, which are typically afforded (in varying degrees) to smaller investors. Were I an existing investor or angel, the definitives adding a threshold would feel like a retrade of the term sheet.
Especially if the intent is to help unfamiliar founders & angels understand what's a "clean" or fair deal, I'd put in a vote that a v2 of this term sheet would clarify the applicability of rights to smaller investors, maybe with some "batteries included" guidance on that point.
You can make arguments like this in negotiations and sometimes they can work. It just depends. As I mentioned elsewhere, this was meant to be more descriptive than prescriptive. Founder vesting/re-vesting is often a negotiation point in a Series A term sheet and the outcomes are varied and fact-dependent enough that it's tough to say that there's a standard here.
Annual and quarterly unaudited is normally implied. Sometimes monthly too. Most good Series A investors understand that audited financials don't make sense this early and their lawyers will draft something like the audit requirement can be waived by the investor in any year, or that audits won't be required until 2-3 years out.
