provided, however, that such a Golden Change of Recommendation may not be made unless and until:   (A)            the Golden Board determines in good faith after consultation with its financial advisors and outside legal counsel that a Golden Intervening Event has occurred;   (B)            the Golden Board determines in good faith, after consultation with its outside legal counsel, that failure to effect a Golden Change of Recommendation in response to such Golden Intervening Event would be a violation of the fiduciary duties owed by the Golden Board to the stockholders of Golden under applicable Law;

  (D)            after giving such notice and prior to effecting such Golden Change of Recommendation and if requested by Labrador, Golden negotiates (and causes its officers, employees, financial advisor and outside legal counsel to negotiate) in good faith with Labrador (to the extent Labrador wishes to negotiate) to make such adjustments or revisions to the terms of this Agreement as would permit the Golden Board not to effect a Golden Change of Recommendation in response thereto; and  (E)            at the end of the four Business Day period, prior to taking action to effect a Golden Change of Recommendation, the Golden Board takes into account any adjustments or revisions to the terms of this Agreement proposed by Labrador in writing and any other information offered by Labrador in response to the notice, and determines in good faith after consultation with its financial advisors and outside legal counsel, that the failure to effect a Golden Change of Recommendation in response to such Golden Intervening Event would be a violation of the fiduciary duties owed by the Golden Board to the stockholders of Golden under applicable Law;
