 FORWARD-LOOKING STATEMENTS  This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “future,” “outlook,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential,” “continue,” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. The forward-looking statements in this presentation relate to, among other things, our anticipated NDA submission dates for Epsolay and Twyneo, estimated timing for the approval and launch of Epsolay and Twyneo, and estimated sales of our product candidates. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties, and other important factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statement, including but not limited to the following: the fact that we have and expect to continue to incur significant losses; our need for additional funding, which may not be available; our ability to complete the development of our product candidates; our ability to obtain and maintain regulatory approvals for our product candidates in our target markets and the possibility of adverse regulatory or legal actions relating to our product candidates even if regulatory approval is obtained; our ability to commercialize our product candidates; our ability to obtain and maintain adequate protection of our intellectual property; our ability to manufacture our product candidates in commercial quantities, at an adequate quality or at an acceptable cost; our ability to establish adequate sales, marketing, and distribution channels; acceptance of our product candidates by healthcare professionals and patients; the possibility that we may face third-party claims of intellectual property infringement; the timing and results of clinical trials that we may conduct or that our competitors and others may conduct relating to our or their products; intense competition in our industry, with competitors having substantially greater financial, technological, research and development, regulatory and clinical, manufacturing, marketing, and sales, distribution and personnel resources than we do; potential product liability claims; potential adverse federal, state, and local government regulation in the United States, Europe, or Israel; and loss or retirement of key executives and research scientists. These and other important factors discussed in the Company's Annual Report on Form 20-F filed with the Securities and Exchange Commission (“SEC”) on March 21, 2019, and our other reports filed with the SEC could cause actual results to differ materially from those indicated by the forward-looking statements made in this presentation. Any such forward-looking statements represent management’s estimates as of the date of this presentation. While we may elect to update such forward-looking statements at some point in the future, unless required by applicable law, we disclaim any obligation to do so, even if subsequent events cause our views to change. Thus, one should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. These forward-looking statements should not be relied upon as representing our views as of any date subsequent to the date of this presentation. This presentation contains trademarks, trade names, and service marks of other companies, which are the property of their respective owners. We do not intend our use or display of other parties' trademarks, trade names, or service marks to imply, and such use or display should not be construed to imply, a relationship with, or endorsement or sponsorship of us by, these other parties.Before you invest, you should read the prospectus in the registration statement and other documents we have filed with the SEC for more complete information about the issuer and this offering.

 WHY SILICA?   FDA approved for topical useProprietary process produces high encapsulation efficiencyPhysical properties of silica shell tuned to modify release of active ingredientSmooth, no-grit feel for userStrong IP protection to 2032 (EPSOLAY®) and 2038 (TWYNEO®)    1  Silica monomers and drug substance are emulsified together   Silica monomers migrate to the oil/water interface in a well-controlled process  A silica shell, microcapsuleis formed   SOL-GEL PROCESS    2  Barrier between entrapped API and skin may reduce irritation and improve complianceAPIs stabilized via microencapsulation, allowing for novel combinationsHurdle for generics to demonstrate similar release profileIf approved, will be first core-shell encapsulation system for topical dermatology products  POTENTIAL BENEFITS    3  Foundation forbranded product pipeline 
 
 CRYO-SEM PICTURE  ENERGY-DISPERSIVE X-RAY SPECTROSCOPY MAPPING  Encapsulated Benzoyl Peroxide (E-BPO)  Skin lipids migrate through the silica shell to promote solubilization of BPO. Dissolved BPO then migrates to skin’s sebaceous follicles  Silica shell wraps BPO crystals and serves as a barrier between BPO crystals and skin, leading to less irritation      Controlled release improves tolerability
