Criteria
Inclusion Criteria:

1. Male outpatients of any race, between 40 and 90 years of age.

2. Clinical signs and symptoms of frequency (>=8 micturitions/day) and urgency (>=2
episodes/day).

3. Urodynamic history consistent with OAB that developed in conjunction with BPO and that
persists for at least 3 months post TURP or PVP, RRP or other obstruction relieving
procedure.

4. OAB inadequately controlled with anticholinergic medications, as per Investigator
opinion.

5. Qmax >12mL/s with a voided volume of >125mL.

6. IPSS >12, with IPSS QoL >3 at study Visit 1.

7. Willing to use clean intermittent catheterization (CIC) to empty the bladder or is
willing to have an indwelling catheter, if necessary following study treatment.

8. Able to understand the requirements of the study, including completing questionnaires
and signing Informed Consent/HIPAA.

Exclusion Criteria:

1. Known history of interstitial cystitis, uninvestigated hematuria, bladder outlet
obstruction due to vesical neck contracture, mullerian duct cysts, urethral
obstruction due to stricture/valves/sclerosis of urethral tumor, radiation cystitis,
genitourinary tuberculosis, bladder calculi, or detrusor-sphincter dyssynergia.

2. Known history of clinically significant cardiovascular disease, cerebrovascular
disease, or arrhythmia.

3. History of spinal cord injury or multiple sclerosis, or other neurological disease
which may be contributing to OAB.

4. Known history of hydronephrosis.

5. Current indwelling catheter, or removal of chronic catheter <1 month prior to study
entry.

6. Non-compliance with wash-out periods for prohibited medications/therapies (Supplement
I).

7. Evidence of Urinary Tract Infection according to local standard of care.

8. Serum PSA of >10ng/mL.

9. 24 hour total volume voided >3000 mL of urine. [As determined by completion of a
patient bladder diary during the screening period]

10. Medical condition that may increase their risk of exposure to botulinum toxin
including diagnosed Myasthenia Gravis, Eaton-Lambert Syndrome, Amyotrophic Lateral
Sclerosis or any other disease that might interfere with neuromuscular function.

11. Allergy or sensitivity to any component of BOTOX® (Section 5.2).

12. Known uncontrolled systemic disease.

13. Evidence of recent alcohol/drug abuse.

14. Subjects who, in the opinion of the Investigator, have a significant condition that
puts them at significant risk, may confound study results, or interfere with study
participation.
