English to Spanish Law/Patents Law: Contract(s)

Hola a todos!
¿Cómo se diría esto en español? La definición dice que: "even though the resale limitations under Rule 144 have been reduced somewhat over the years, investors still often look for the issuer in a private placement transaction to provide them with a possible liquidity event prior to the end of the holding period. Consequently, investors often require, and issuers often grant, some form of a registration rights agreement to be signed, either as part of the stock purchase agreement or as a separate side agreement thereto. These registration rights provisions typically require the company to do one of two things: (1) register the shares or a portion of the shares within some specified time-frame, at either the company’s or the investor’s expense (“demand registrations”); or, (2) include the shares or a portion of the shares in any future public offerings that the company makes, if any."
