4.5 Specific Performance. Each Stockholder agrees with Synquest as to itself that if for any reason a Stockholder fails to perform any of its agreements or obligations under this Agreement, immediate and irreparable harm or injury to Synquest would be caused as to which money damages would not be an adequate remedy. Accordingly, each Stockholder agrees that, in seeking to enforce this Agreement against such Stockholder, Synquest shall be entitled, in addition to any other remedy available at law, equity or otherwise, to specific performance and injunctive and other equitable relief restraining any violation or threatened violation of the provisions of this Agreement without the necessity of Synquest posting a bond or other form of security.

The provisions of this Section 4.5 are without prejudice to any other rights or remedies, whether at law or in equity, that Synquest may have against such Stockholder for any failure to perform any of its agreements or obligations under this Agreement.
