The Connecticut Registration Rights Agreement between Visible Genetics, Inc. and the purchasers of common shares of the company is a contractual agreement that outlines the rights and responsibilities of the parties involved regarding the registration of securities. This agreement ensures that the purchasers of common shares have the ability to register their shares with the relevant regulatory authorities, allowing them to have the freedom to sell or transfer their shares in compliance with applicable securities laws. It is important to note that there may be variations of the Connecticut Registration Rights Agreement between Visible Genetics, Inc. and its common share purchasers. These variations can be categorized into two main types: demand registration rights and piggyback registration rights. Demand registration rights refer to the purchaser's ability to require the company to register their shares on their behalf. If the purchasers wish to sell or transfer their shares and there is no existing effective registration statement covering those shares, they can demand the company to file a registration statement. This allows the purchasers to have a streamlined process for liquidating their shares in the market. On the other hand, piggyback registration rights refer to the right of the purchasers to include their shares in a registration statement filed by the company for its own offerings, such as initial public offerings or secondary offerings. This allows the purchasers to take advantage of the company's registration efforts and piggyback on the registration process without incurring additional costs or efforts. Both types of registration right agreements provide flexibility and liquidity to the purchasers of common shares, ensuring that they have the ability to sell or transfer their shares when desired. Such arrangements foster investor confidence and encourage investment in Visible Genetics, Inc. Overall, the Connecticut Registration Rights Agreement serves as a crucial legal document that outlines the specific rights and obligations of the company and its common share purchasers, ensuring compliance with securities laws and providing a framework for the registration of shares.
