Re:	Quadriga Superfund, L.P.
	Registration Statement on Form S-1

Dear Sir or Madame:

     We have acted as your counsel in connection with the preparation and filing with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended, a Registration Statement on Form S-1 to be filed with the SEC on or about August 18, 2006 (the “Registration Statement”), relating to Series A and Series B Units of Limited Partnership Interest of Quadriga Superfund Fund, L.P. (the “Fund”), a Delaware limited partnership.

     We have reviewed such data, documents, questions of law and fact and other matters as we have deemed pertinent for the purpose of this opinion. Based upon the foregoing, and based upon Superfund Capital Management, Inc.’s belief that all of the income expected to be generated by each Series will constitute “qualifying income,” we hereby confirm our opinion set forth under the caption “Federal Income Tax Aspects” in the Prospectus and Disclosure Document constituting a part of the Registration Statement that each Series will be classified as a partnership for federal income tax purposes and will not be considered a publicly traded partnership taxable as a corporation for federal income tax purposes. Also, the summary set forth under the caption “Federal Income Tax Aspects” fairly and accurately describes (subject to the uncertainties referred to therein) the material federal income tax consequences to United States individual taxpayers that invest in Series A or Series B of the Fund.

     The opinions expressed above are based solely upon the current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury regulations promulgated thereunder (the “Regulations”), pertinent judicial authorities, rulings and other administrative interpretations of the Internal Revenue Service and such other authorities as we have considered relevant. It should be noted that the Code, the Regulations and such judicial authorities, rulings and administrative interpretations and other authorities are subject to change

Our opinions assume the accuracy of the facts as represented in documents reviewed or as described to us and could be affected if any of the facts as so represented or described are inaccurate.

     We express no opinion concerning federal income tax matters relating to the above-described transaction except as expressly set forth above and no opinion concerning the application of any state, local or foreign tax laws to such transaction.
