ITEM 4.  PURPOSE OF TRANSACTION.

       Item 4 is hereby amended by adding at the end thereof the following:

On May 12, 2010, the Reporting Persons sent the following letter to the Issuer's board of directors:

Dear Gentlemen:

It has always been our belief that Cedar Fair has the best operating management team in the industry with world-class entertainment venues. We were pleased that we could come to a consensual resolution concerning the upcoming election of directors and think that this cooperation will lead to a stronger board that will only serve to enhance unitholder value. While we acknowledge that we cannot offer much in the way of useful suggestions that you do not already know in operating an amusement park, we do hope to bring up some thoughtful items for discussion involving your capital structure and the optimal dividend policy for such a capital structure.

As part of the process of rebuilding unitholder value, we believe the company should be able to reinstate at least a $0.50 annual distribution per unit and perhaps more in the near future. And since we are in the process of working with you to identify two new independent directors for the company's board, it follows that these two new directors should have a key role in determining the level of distributions going forward. However, in order to have this input, it is imperative that these directors also have a key role during the company's refinancing discussions with J.P. Morgan to ensure that the company has the flexibility under its credit agreements to make whatever ultimate distributions are agreed upon by the full board.

I'm sure you would agree it would be somewhat pointless for the company to have agreed to invite these new directors onto the board to allow fresh ideas to circulate, and then not to have them involved in the two most important decisions -- restoring the distribution and refinancing the debt -- currently facing this board with ramifications for years to come.

We believe a minimum of a $0.50 distribution is not only possible but also an absolute necessity and should be begun as soon as possible. The company owes this to the unitholders, many of whom made their investments based upon the distribution and who also need it to pay their taxes related to this investment. The company has projected its Earnings Before Interest Taxes Depreciation and Amortization (EBITDA) to be $320 to $340 million during 2010, which very closely compares to 2007 EBITDA of $340 million, a year when it distributed $1.90 per unit. And the debt at the company as of year-end 2009 was actually lower than the debt level at the end of 2007 by close to $125 million.

Put simply, it is hard to understand why the company could not make at minimum a $0.50 distribution per unit this year when it is projected to generate similar EBITDA and has less debt than in 2007 when it made a $1.90 distribution per unit. In our view, a very reasonable argument could also be made for a $1.00 distribution based on the company's own dividend history and relative performance.

We understand that you may also desire to reduce debt, but we believe a $0.50 to $1.00 distribution would leave at least $60 million to $30 million of cash flow available to pay down debt based upon the company's public statements during the most recent investor conference call. This would still leave the company with less debt than it would have had under the board-approved Apollo Global Management buyout, which you and the management team were presumably comfortable with. And as we said above, the company still has approximately $125 million less debt today than it did when it was paying the $1.90 distribution.

We believe the improved state of the credit markets today will allow the company to renegotiate the covenant restriction that currently prevents the distribution. Assuming this is the case, management and the board would be the ones then left to decide the right level of distribution. Therefore, we plan to encourage all unitholders to take this opportunity to express their views directly to you on this important matter.

Q Funding III and Q4 Funding continue to believe Cedar Fair has numerous options to unlock the value of its units and are very excited about the company's prospects. We look forward to continuing to work cooperatively with the company to maximize unitholder value.



Sincerely,



Q Funding III & Q4 Funding
