     2.2   No Conflict. Neither the execution and delivery of this Agreement by such Stockholder, the consummation of the transactions contemplated hereby, nor the performance by such Stockholder of its obligations hereunder will, (a) require any consent, approval, authorization or permit of, registration, declaration or filing (except for such filings as may be required under the federal securities laws or the Xxxx-Xxxxx-Xxxxxx Antitrust Improvement Act of 1976, as amended, and the rules and regulations thereunder (the “HSR Act”)) with, or notification to, any governmental entity, (b) result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation, or acceleration) under any contract, agreement, instrument, commitment,
