The words “believe,” “may,” “might,” “will,” “aim,” “estimate,” “continue,” “would,” “anticipate, ”“intend,” “expect,” “plan” and similar words are intended to identify estimates and forward - looking statements. Our estimates and forward - looking statements are mainly based on our current expectations and estimates of future events and trends, which affect or might affect our businesses and operations. Although we believe that these estimates and forward - looking statements are based upon reasonable assumptions, they are subject to many risks and uncertainties and are made in light of information currently available to us. Our estimates and forward - looking statements may be influenced by the following factors, among others : risks related to the costs, timing, regulatory review and results of our studies and clinical trials; our ability to obtain FDA approval of our product candidates; differences between historical studies on which we have based our ongoing and planned clinical trials and actual results from our trials; our anticipated capital expenditures, our estimates regarding our capital requirements, and our need for future capital; our liquidity and working capital requirements; our expectations regarding our revenues, expenses and other results of operations; the unpredictability of the size of the markets for, and market acceptance of, any of our products; our ability to sell any approved products and the price we are able realize; our need to obtain additional funding to develop our products, and our ability to obtain future funding on acceptable terms; our ability to retain and hire necessary employees and to staff our operations appropriately; our ability to compete in our industry and innovation by our competitors; our ability to stay abreast of and comply with new or modified laws and regulations that currently apply or become applicable to our business; estimates and estimate methodologies used in preparing our financial statements; the future trading prices of our common stock and the impact of securities analysts’ reports on these prices; and the risks set out in our filings with the SEC, including our Annual Report on Form 10 - K. Estimates and forward - looking statements involve risks and uncertainties and are not guarantees of future performance. As a result of known and unknown risks and uncertainties, including those described above, the estimates and forward - looking statements discussed in this material might not occur and our future results and our performance might differ materially from those expressed in these forward - looking statements due to, including, but not limited to, the factors mentioned above.

VEN 307: Diltiazem Cream Novel Treatment for Anal Fissures

 
 

Anal Fissures: Cause and Management Increased sphincter tone Local ischemia Tear (fissure) in anal canal Cause Severe pain on defecation Treatment Options Control constipation, topical steroids Reduce sphincter tone Compounded t opical drugs: • GTN* • D iltiazem Botox Surgery Sphincters (muscles) Anal fistula Anal Fissure 1.1 million office visits/year † * Rectiv (topical GTN) recently approved by FDA; launched 3/2012 by Aptalis . † Physician Drug & Diagnosis Audit (PDDA), 2010. 4

 
 

VEN 307 ( Diltiazem ) Summary 2% Topical Diltiazem Cream Applied Peri - anally TID Mechanism of Action » Topical c alcium channel blocker Relaxes the internal anal sphincter, reducing pain and increasing tissue blood flow Preclinical Safety » Preclinical topical safety with 2% diltiazem twice daily for ninety days Clinical Pharmacology » Topical has < 10% of the systemic exposure as oral dosage but significantly greater effect on sphincter tone (i.e ., blood levels do not predict activity). Low exposure = better tolerability than oral diltiazem Clinical Data » Numerous clinical trials with ~1,200 subjects Infrequent mild adverse events (AE) reported Similar or better reduction in pain, significantly better tolerability than with nitroglycerin (GTN) » First pivotal trial complete: 3 arms, 465 subjects, significant improvement vs placebo, tolerability confirmed » Second PH III ongoing; data expected Q1 - 2014 5

 
 

FDA meeting (EOPII/pre - NDA) 8/30/2012: » NDA to include: x Cutaneous sensitivity/irritation and formal PK data (completed) x Short - term tox studies - completed (FDA confirmed acute episodic use – long term tox and clinical studies not required) x 2 pivotal trials x 1 pivotal trial completed in EU 2012 □ Second pivotal trial: design, endpoints etc accepted by FDA; data expected in Q1 - 2014 x CMC: 700Kg lots of drug product in addition to 70Kg lots used in clinical studies 6 NDA submission planned for Q2 - 2014

 
 

Formal PK and cutaneous tolerability clinical studies 7 x PK ▪ 1 US site, 12 subjects: sequential dosing of all subjects with diltiazem 2% topical single and multi - dose, and oral to determine PK in AF patients ▪ All PK parameters were as expected and the systemic exposure to diltiazem from topical diltiazem compared to oral diltiazem was confirmed at <10% x Cutaneous tolerability ▪ Sensitization and Irritation studies, 200 and 35 healthy volunteers respectively ▪ Diltiazem 2%, vehicle , saline control, active control (SLS )* ▪ The irritation scores were similar for diltiazem , placebo, and saline, all significantly better than SLS (active control) ▪ There were minimal AEs and no severe or serious AEs ▪ No irritation or sensitization potential with drug product or vehicle (placebo in PH III trials) * Saline solution

 
 

First Pivotal Phase III Trial » FDA (Analgesia Division) pre - IND meeting conducted in August 2007 Achieved clarity on primary endpoint: Reduction in pain Confirmed safety database and toxicology requirement » Phase III trial conducted by SLA Pharma (Ex - North America licensor) 3 arms with 155 patients per arm in 31 sites in Europe 2% and 4% diltiazem three times a day (TID) and placebo in 31 sites across Europe Romania (11 centers, 66%), Bulgaria, Spain, UK, Germany and Lithuania 94.6% of subjects completed the 12 - week study Primary outcome: Change from baseline in average of worst anal pain associated with or following defecation at Week 4 on an 11 - point numerical rating scale ( Likert - like scale) Selected secondary outcomes: Change from baseline in average of daily overall anal fissure - related pain at Week 4 Proportion of subjects who have complete healing of anal fissure at Week 8 Change in the Patient’s Global Impression of Improvement (PGI - I) at Week 4 Statistical analysis consistent with Division guidelines re. missing data 8

 
 

Summary of First Phase III Results (May 14, 2012) » Double - blind, placebo - controlled clinical trial randomized 465 subjects to diltiazem hydrochloride 4% or 2% by weight (w/w) cream, or placebo, applied topically three times daily (TID) for 8 weeks, followed by a 4 week blinded observation period. Conducted by licensor SLA in Europe » At 4 weeks, the 2% diltiazem treatment arm demonstrated improvements compared to placebo: Primary endpoint of average of worst anal pain associated with or following defecation: Pain score improvement of 0.43 for 2% diltiazem (p=0.0122) Secondary endpoint of overall anal - fissure - related pain: Pain score improvement of 0.42 for 2% diltiazem (p=0.0143) » 2% diltiazem improved the Patient’s Global Impression of Improvement measure at Week 4 (p = 0.0084 ) and at Week 8, healing was improved for the 2% diltiazem arm (31.2% healing; p=0.0426) compared to placebo (23.9%) » Effects of 4% were similar or less (dose asymptote for efficacy = 2%) » Adverse events (i.e., incidence of headaches) were similar across all 3 treatment arms (4%, 2%, placebo) 9

VEN 307 Life Cycle: » Licensed from SLA P harma for U.S. and Canada in return for single digit royalties and approval milestones » U.S. patent protects IP through February 2018 and with HW extension to August 2019. Possible pediatric extension to Q2 - 2020 (written request process initiated). After expiration, the Company expects generic approval to be difficult due to topical dosage, trade secret protection, re - formulation obstacles and the probable need for clinical study and comparative PK data in AF patients » Have completed technical development of four extended release formulations All patentable with expected protection through 2033 All B.I.D. or O.D. At least one Phase 3 trial with one extended release formulation will be required (if one formulation is acceptable in manometry /PK studies). 12
