September 25, 1997

Securities and Exchange Commission 
450 5th Street N.W.
Washington, D.C. 20549

Gentlemen:

This letter is written in response to the  requirement of Rule  12b-25(c)  under
the Securities and Exchange Act of 1934 and in  satisfaction of item (c) of Part
II of Form 12b-25.

We are the independent  auditors of Worldwide  Petromoly,  Inc. (formerly Ogden,
McDonald & Company - the "Registrant"). The Registrant has stated in Part III of
its filing on Form 12b-25 that it is unable to timely file, without unreasonable
effort or expense,  its Annual Report on Form 10-KSB for the year ended June 30,
1997,  because  our  Firm  has not yet  completed  our  audit  of the  financial
statements of the  Registrant for the year ended June 30, 1997, and is therefore
unable to furnish the required opinion on such financial statements.

We hereby advise you that we have read the statements  made by the Registrant in
Part III of its  filing  on Form  12b-25  and  agree  with the  statements  made
therein.  We are  unable to  complete  our audit of the  Registrant's  financial
statements  and furnish the  required  opinion for a timely  filing  because the
above  referenced Form 10-KSB will include the balance sheet as of June 30, 1997
and the  statements of  operations,  stockholders'  equity and cash flows of the
Registrant  for the years ended June 30 1997 and 1996,  of which the 1996 fiscal
year will be on a  proforma  basis to  include  the  results  of  operations  of
Worldwide  Petromoly  Corporation  which have been  recasted  on a June 30, 1996
fiscal year basis.  Prior to the July 22, 1996,  reverse  merger  between Ogden,
McDonald & Company and Worldwide Petromoly  Corporation,  the latter company was
privately-held with a December 31, fiscal year end. As a result, we have not yet
had  sufficient  time to  complete  the  auditing  procedures  which we consider
necessary in the circumstances.


Very truly yours,


/s/ BDO Seidman, LLP
