POWER OF ATTORNEY                                                               

Know all by these presents, that the undersigned hereby authorizes Richard A.   
Miller, M.D. and Leiv Lea of Pharmacyclics, Inc. (the "Company"), to execute for
and on behalf of the undersigned, in the undersigned's capacity as a director of
the Company, Forms 3, 4 and 5, and any amendments thereto, and cause such       
form(s) to be filed with the United States Securities and Exchange Commission   
pursuant to Section 16(a) of the Securities Act of 1934, relating to the        
undersigned's beneficial ownership of securities in the Company. The undersigned
hereby grants to each such attorney-in-fact full power and authority to do and  
perform any and every act and thing whatsoever requisite, necessary, or proper  
to be done in the exercise of any of the rights and powers herein granted, as   
fully to all intents and purposes as the undersigned might or could do if       
personally present, with full power of substitution or revocation, hereby       
ratifying and confirming all that such attorney-in-fact, or such                
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be  
done by virtue of this power of attorney and the rights and powers herein       
granted. The undersigned acknowledges that the foregoing attorneys-in-fact, in  
serving in such capacity at the request of the undersigned, are not assuming,   
nor is the Company assuming, any of the undersigned's responsibilities to comply
with Section 16 of the Securities Exchange Act of 1934.                         

This Power of Attorney shall remain in full force and effect until the          
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the  
undersigned's holdings of, and transactions in, securities issued by the        
Company, unless earlier revoked by the undersigned in a signed writing delivered
to the foregoing attorneys-in-fact.                                             

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be     
executed as of this 24th day of July, 2008.
