**Item 5. Interest in Securities of the Issuer**

**(a)**
See responses to Items 11 and 13 on the attached cover pages.

**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

In connection with the Closing, on August 25, 2021, each of KV Seed B, KV Seed B (CF), and KV V (the "KV Funds") entered into a Second Amended and Restated Registration Rights Agreement (the "Registration Rights Agreement") with the Issuer (then known as Vector Acquisition Delaware Corporation), Vector Acquisition Partners, L.P., certain legacy investors of Vector party thereto and certain other investors of Legacy Rocket Lab party thereto, pursuant to which the KV Funds are entitled to registration rights with respect to their shares of Common Stock. The Registration Rights Agreement provides that the Issuer will, within 45 calendar days following the Closing, file with the SEC a shelf registration statement (the "Registration Statement") pursuant to Rule 415 of the Securities Act of 1933, as amended, and use commercially reasonable efforts to cause such Registration Statement to be declared effective as soon as practicable after the filing thereof, but no later than the earlier of (a) the 90th calendar day following the filing date if the SEC notifies the Issuer that it will "review" the Registration Statement and (b) the tenth business day after the date the Issuer is notified by the SEC that the Registration Statement will not be "reviewed" or will not be subject to further review.

At any time when there is an effective shelf registration statement, the KV Funds may request to sell all or a portion of their registrable securities in an underwritten offering and the Issuer will facilitate such offering, provided that the registrable securities proposed to be sold in the offering have a total offering price of at least $50 million. Such demand registration rights are subject to certain issuer suspension periods, limitations on frequency and timing of demands and certain other conditions. In addition, the Registration Rights Agreement grants the KV Funds "piggyback" registration rights, subject to certain exceptions including that there cannot be an effective shelf registration statement available for the resale of holders' registrable securities at such time as piggyback rights are exercised.

The Registration Rights Agreement also includes customary indemnification provisions. Further, the Issuer will bear all expenses incident to registering the securities, including any underwritten offerings, except such expenses shall not include any selling expenses such as underwriters' commissions and discounts, brokerage fees, underwriter marketing costs and legal fees incurred by the holders above a specified amount.
