Risks and Investment Considerations

An investment in the Series A-2 Preferred is speculative and involves a high degree of risk. Investors should understand the various risks of investment and should be able to afford to bear such risks, including, without limitation, the risk of losing their entire investment.

Set forth below are certain risks that are material and should be considered by Investor. It should be recognized that the risk factors set forth below are those that, at the date of this Agreement, appear to the Company the most likely to be significant. Investor should realize, however, that factors other than those set forth below may ultimately affect an investment in the Company in a manner and to a degree that cannot be foreseen at this time.

Speculative Investment. An investment in the Series A-2 Preferred is speculative and involves a high degree of risk. Investor should understand the various risks of investment and should be able to afford to bear such risks, including, without limitation, the risk of losing his entire investment.

Development Stage Company. The Company is a development stage company without any operating history. There can be no assurance that the Company will be able to implement its business plan, raise sufficient capital to fund its development or achieve a level of operating revenues or income sufficient to enable the Company to continue as a going concern. It has no commercial products and its products in development require significant further research, development, testing, and regulatory clearances and are subject to the risks of failure inherent in the development of products based on new technologies. These risks include the possibilities that the Company’s technology or any or all of its product candidates will be found to be unsafe, ineffective or toxic, especially in immunosuppressed individuals, or fail to receive necessary regulatory clearances to develop or approve the products; that the product candidates, even if found to be safe and effective, will be difficult to manufacture on a large scale or uneconomical to market; that the product candidates will be stable enough for commercialization; that proprietary rights of third parties will preclude the Company from marketing products; or that third parties will market superior or equivalent products. There can be no assurance that the Company’s research and development activities will result in any commercially viable products.

Delays in the Completion of Human Clinical Testing Could Result in Increased Costs and Delay or Limit our Ability to Generate Revenues. Delays in the completion of clinical testing could significantly affect our product development costs. We do not know whether planned clinical trials will be completed on schedule, if at all. The commencement and completion of clinical trials can be delayed for a number of reasons, including delays related to:

obtaining regulatory approval to commence and continue a clinical trial;
reaching agreement on acceptable terms with any prospective clinical research organizations, or CROs, and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

manufacturing sufficient quantities and quality of our product candidate(s) for use in clinical trials;

obtaining institutional review board approval to conduct a clinical trial at a prospective site;

recruiting and enrolling patients to participate in clinical trials for a variety of reasons, including competition from other clinical trial programs for the treatment of similar conditions; and

signing-up patients who have consented to participate in a clinical trial but may withdraw from the study at any time due to side effects from the investigational product and/or other therapy, lack of efficacy and/or disease progression, personal reasons, or who are lost to further follow-up.

Clinical trials may also be delayed or discontinued as a result of ambiguous or negative interim results. In addition, a clinical trial may be suspended or terminated by us, an institutional review board overseeing the clinical trial at a clinical trial site (with respect to that site), the FDA, or other regulatory authorities due to a number of factors, including:

failure to conduct the clinical trial in accordance with US, international and/or local regulatory requirements, or in compliance with the study protocols;

unforeseen safety issues; and

lack of adequate funding to continue the clinical trial.

Additionally, changes in regulatory requirements and guidance may occur, and we may need to amend clinical trial protocols or our development plan to reflect these changes. Amendments may require us to resubmit our clinical trial protocols to institutional review boards for reexamination, which may impact the costs, timing or successful completion of a clinical trial. If we experience delays in completion of, or if we terminate any of our clinical trials, the commercial prospects for our product candidates may be harmed, and our ability to generate product revenues will be delayed. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.

Technological Uncertainty. The pharmaceutical industry is rapidly evolving, and it is expected to continue to undergo significant and rapid technological changes. Rapid technological development could result in actual and proposed products, services or processes becoming obsolete before the Company recovers a significant portion of its related research, development and capital expenses. Many companies are presently searching for treatments for cancers and other diseases. Because of such intense competition, it is possible that a competitor will have a marketable product prior to any developed by the Company or will develop a product with safety or effectiveness that exceeds those of any of the Company’s products or will attract patients to their clinical studies instead of the Company’s proposed studies.

No Market for Series A-2 Preferred. No public market for the Company’s securities presently exists, it is unlikely that one will develop in the future and investors may find it impossible to liquidate an investment in the Series A-2 Preferred at a time when it may desire to do so.

Key Employees. The Company will be dependent upon the availability of its senior executive officers who will be responsible for overall management of the Company and the development and marketing efforts of the Company’s technologies and products.

Restrictions on Transfer. The transfer of shares of Series A-2 Preferred is restricted. The shares must be acquired for investment purposes only and not with a view to resale. The shares will not be registered under the Securities Act of 1933, as amended, or the securities laws of any state (in reliance upon exemptions that depend in part upon the investment intent of the investors). The Company has no present intention of registering the Units in the future. In addition, any transfer must comply with all applicable Federal and state securities laws.

Taxes. All individuals contemplating an investment in the Company are responsible for their own tax consequences. Holders of Notes that are converting accrued interest into equity may realize taxable gain in connection with the amount of interest converted.

Industry Risks. Substantial additional research and development is necessary in order to determine whether the Company’s products will be able to compete with competitors on the basis of cost and effectiveness. The Corporation will be dependent upon the availability of its key scientific personnel and senior executive officers who will be responsible for overall research and management of the Company and the development and marketing efforts of the Company’s technologies and products.

Regulatory Approval. The principal products that the Company is developing are subject to prior regulatory approval before they can be sold to the public. Such regulatory approvals have not been applied for or granted in any of the countries in which the Company plans to sell such products. Delays in obtaining FDA and other regulatory approvals would have an adverse effect upon the Company’s business prospects and could lessen the Company’s competitive advantages. The extent of such regulatory review will affect the amount of future capital required by the Company.

Competition. The Company will face strong competition from other businesses offering similar services. In many instances, such competitors are better financed and already have an established customer network that will be difficult for the Company to penetrate. The barriers to entry for the Company’s business are low.

Accumulated Deficit. The Company is a development stage entity and, therefore, has generated no revenues or earnings from sales of products and no product revenues or earnings are expected for years. The Company will be required to conduct significant research, manufacturing, development, testing, and regulatory compliance activities which, together with projected general and administrative expenses, are expected to result in significant and increasing operating losses for the foreseeable future.

Risk of Product Liability. Clinical trials, marketing, or commercial use of any of the Company’s potential products may expose the Company to liability claims from the use of such products and conduct of clinical trials. The Company has obtained for prior and current human clinical trials, and intends to obtain (if available at a commercially reasonable cost), only limited product liability insurance at such time that human clinical trials are conducted. There can be no assurance that the Company will be able to obtain and maintain such insurance, obtain additional insurance, or that sufficient coverage can be acquired at a feasible cost. An inability to obtain or maintain insurance at acceptable cost or otherwise protect against potential product liability claims could prevent or inhibit the commercialization of products developed by the Company. A product liability claim or recall could have a material adverse effect on the business or financial condition of the Company.

Uncertainty of Government Regulatory Requirements; Lengthy Approval Process. Because the Company’s technology is a commercially new technology and has not been extensively tested in humans, the regulatory requirements governing gene transfer products and related clinical procedures are uncertain and may be subject to substantial review by various governmental and regulatory authorities in the United States and foreign countries. FDA regulatory review may result in extensive delay in regulatory approval of any of the Company’s product candidates. The Company plans to change its manufacturing process from the current serum containing process to our defined media process and there can be no guarantee that the regulatory authorities will approve this new process in a timely manner or ever. Also as a consequence of the manufacturing change there may be a requirement to do more preclinical safety or efficacy studies, develop new manufacturing and release assays and repeat all or part of the ascending dose safety study in humans. Regulatory requirements ultimately imposed could affect adversely the Company’s ability to test, manufacture or market products.

Future Capital Needs; Uncertainty of Additional Funding. The Company will require substantial funds to conduct the research and development and preclinical and clinical testing of its product candidates and product leads, to establish commercial-scale manufacturing capabilities and to market its product candidates. The Company’s future capital requirements will depend on many factors, including: scientific progress in its drug discovery programs; the magnitude and number of these programs; progress and findings in preclinical testing and clinical trials; the time and costs involved in obtaining regulatory approvals; the costs involved in filing, prosecuting and enforcing patent claims; competing technological and market developments; changes in its existing research relationships; the ability of the Company to establish collaborative arrangements; the cost of manufacturing scale-up; and effective commercialization activities and arrangements. The Company expects that the Company’s existing funds, together with the funds generated by this offering and the interest earned thereon, will be insufficient to fund the Company’s activities for any discernible period. As a result, additional funds will need to be raised. The Company intends to seek such additional funding through private or public financings, as well as collaborative arrangements. There can be no assurance that additional financing will be available, or, if available, that it will be available on acceptable terms. If adequate funds are not available, the Company may be required to delay, scale back or eliminate one or more of its drug development programs or obtain funds through arrangements with collaborative partners or others that may require the Company to relinquish rights to certain of its technologies or product candidates that the Company would not otherwise relinquish. If additional funds are raised by issuing equity or convertible securities, dilution to existing stockholders will result.

Dependence on Others; Collaborators. The Company’s strategy for the research, development and commercialization of its products may require entering into various arrangements with third party manufacturers, corporate collaborators, licensors, licensees and others, and is dependent upon the subsequent success of these outside parties in performing their responsibilities. CPP is currently engaged in a manufacturing and supply relationship with Sanofi-Aventis and also with Xxxxxx Pharmaceuticals. The Company is dependent on them for ongoing supply, packaging, analytical, regulatory, scale up, manufacturing-changes, and other elements required for supplying the Products to clinical trial sites and eventually to the marketplace.

Uncertainty of Patent Position and Proprietary Rights. Although the company has received orphan status in both the EU and US, other Companies might also apply for orphan status (and first product to market will enjoy the benefits of orphan status). Although the Company has applied for certain patents critical to the development of its product, such patents have not been approved.

Uncertainty regarding third-party reimbursement and healthcare cost containment initiatives may limit our returns. The ongoing efforts of governmental and third-party payors to contain or reduce the cost of healthcare may affect our ability to commercialize our products successfully. Governmental and other third-party payors continue to attempt to contain healthcare costs by:

challenging the prices charged for health care products and services;

limiting both coverage and the amount of reimbursement for new therapeutic products;

denying or limiting coverage for products that are approved by the FDA but are considered experimental or investigational by third-party payors;

refusing in some cases to provide coverage when an approved product is used for disease indications in a way that has not received FDA marketing approval; and

denying coverage altogether.

The trend toward managed healthcare in the United States, the growth of organizations such as health maintenance organizations, and legislative proposals to reform healthcare and government insurance programs could significantly influence the purchase of healthcare services and products, resulting in lower prices and reducing demand for our products. In addition, in almost all European markets, pricing and choice of prescription pharmaceuticals are subject to governmental control. Therefore, the price of our products and their reimbursement in Europe will be determined by national regulatory authorities.

Even if we succeed in bringing any of our proposed products to the market, they may not be considered cost-effective and third-party reimbursement might not be available or sufficient. If adequate third-party coverage is not available, we may not be able to maintain price levels sufficient to realize an appropriate return on our investment in research and product development. In addition, legislation and regulations affecting the pricing of pharmaceuticals may change in ways adverse to us before or after any of our proposed products are approved for marketing.

Even if our drug candidates are successful in clinical trials, we may not be able to successfully commercialize them.

Since our inception in 2008, we have dedicated substantially all of our resources to the research and development of our technologies and related compounds. All of our compounds currently are in research or development, and have not received marketing approval.
