  (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 Superior Proposal would breach the fiduciary duties owed by the Golden Board to the stockholders of Golden under applicable Law;

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 Golden Competing Proposal remains a Golden Superior Proposal and that the failure to effect a Golden Change of Recommendation in response to such Golden Superior Proposal would breach the fiduciary duties owed by the Golden Board to the stockholders of Golden under applicable Law; provided that in the event of any material amendment or material modification to any Golden Superior Proposal (it being understood that any amendment or modification to the economic terms of any such Golden Superior Proposal shall be deemed material), Golden shall be required to deliver a new written notice to Labrador and to comply with the requirements of this Section 6.3(e) (iv)with respect to such new written notice, except that the advance written notice obligation set forth in this Section 6.3(e)(iv)shall be reduced to two Business Days;

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 breach the fiduciary duties owed by the Golden Board to the stockholders of Golden under applicable Law;   (C)            Golden provides Labrador written notice of such proposed action and the basis thereof four Business Days in advance, which notice shall set forth in writing that the Golden Board intends to consider whether to take such action and includes a reasonably detailed description of the facts and circumstances of the Golden Intervening Event;   (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 breach the fiduciary duties owed by the Golden Board to the stockholders of Golden under applicable Law;
