PROSPECTUS SUMMARY

This summary provides an overview of selected information contained elsewhere in this prospectus and does not contain all of the information you should consider before investing in our common stock. You should carefully read the prospectus and the registration statement of which this prospectus is a part in their entirety before investing in our common stock, including the information discussed under "Risk Factors" beginning on page 7 and the financial statements and notes thereto that appear elsewhere in this prospectus. Unless otherwise indicated, all information in this prospectus assumes the underwriters do not exercise their option to purchase up to shares of our common stock to cover overallotments.

Overview of Our Business

We are a drug delivery company specializing in proprietary dissolving thin film pharmaceutical products. Our thin film, which is similar in size, shape and thickness to a postage stamp, dissolves rapidly and utilizes a novel process and proprietary encapsulation compositions to mask the taste of the drug contained within the film. We believe these qualities render our thin film easy to use and consequently will improve patient compliance, providing a significant benefit to patients and their prescribing physicians and healthcare institutions. Our thin film drug delivery technology is currently used in the over-the-counter, or OTC, marketplace and we are developing thin film containing prescription drugs. By incorporating approved drugs with soon-to-expire or expired patents into our thin film, we believe we can protect the billions of dollars of drug revenues important to our existing and future pharmaceutical partners. Furthermore, we are building the infrastructure required to produce our thin film rapidly and at scale.

We believe our thin film drug delivery technology has several material benefits over existing drug delivery forms and should enjoy strong physician, patient and consumer acceptance. Our thin film improves convenience and ease of use through discretion and portability and precludes the need for water or liquids. Our thin film may also improve dosing accuracy relative to liquid formulations thereby ensuring proper dosing for the pediatric, geriatric and mentally ill patients where proper administration is often difficult. In addition, our thin film provides ease of dosing for patients with conditions that make it difficult to swallow other solid dosage forms such as tablets or capsules.

Our proprietary thin film drug delivery technology is supported by a significant portfolio of intellectual property, which we believe differentiates us from our competitors. We believe this technology will enable pharmaceutical companies to better manage the life cycle of their products. By combining our thin film drug delivery technology with existing drugs, we believe our thin film can strategically differentiate existing or soon-to-be genericized drugs from potential generic competitors and can help protect branded prescription products against existing or new generic entries by providing additional patent protection or exclusivity in the marketplace. Additionally, we believe our thin film drug delivery technology can also be used to create new drug products with improved efficacy.

We believe we are the only company completely dedicated to thin film as a drug delivery dosage form and have created a vertically integrated infrastructure to ensure leadership capabilities in the critical activities of drug tastemasking, analytical development, global formulation development, manufacturing and packaging. We have invested significantly in our model of vertical integration to develop an operational infrastructure that we believe will position us to seamlessly commercialize products in concert with our partners' respective sales forces.

Our Product Development

of SFIs to develop thin film versions of existing products, which we ultimately intend to bring to market with a partner. We have also been engaged by pharmaceutical partners to develop thin film versions of existing prescription products. In the future, we expect to partner with pharmaceutical companies to deliver new prescription products with improved efficacy. We also expect to continue to develop and commercialize thin film products in the OTC and consumer marketplace.

Self-Funded Initiatives

We are developing thin film versions of a series of existing blockbuster prescription drugs. We believe that these products can be approved on the basis of limited clinical data and on a development to approval timeline of 24 to 30 months. We plan to advance development of these initiatives until we realize certain product-specific development milestones, at which point we expect to attract partners with whom we will commercialize these thin film products. We have a large pool of drugs to choose from for thin film development due to its large load capacity. We estimate there to be over 400 drug candidates suitable for development utilizing our thin film drug delivery technology and we intend to carefully evaluate those candidates to determine their suitability for internal development.

We are currently self-funding the development of the following pharmaceutical products:

Our Business Strategy

Our strategy is to develop and partner to commercialize innovative thin film strip products in the prescription and OTC pharmaceutical markets. We have established and seek to maintain a leadership position in thin film drug delivery technology through continued development of our technology and our intellectual property portfolio. We believe that pharmaceutical companies will want to partner with us to extend the life cycle of their products, defend against patent expiration, protect against generic encroachment and differentiate their products in competitive categories. To achieve these goals, our strategy includes the following key elements:

•: Self-fund the development of thin film versions of existing prescription products with a goal of partnering later;
•: Develop thin film versions of existing prescription products with pharmaceutical partners;
•: Partner with pharmaceutical companies to deliver new prescription products with improved efficacy;
•: Position ourselves to be a partner of choice for thin film drug delivery technology through vertical integration;
•: Continue to develop our intellectual property portfolio to position ourselves as the market leader in thin film drug delivery technology; and
•: Continue to commercialize products in the OTC marketplace to leverage our existing infrastructure to generate near-term revenue and cash flow.

Our Risks

We are subject to a number of risks which could adversely affect our business, offset or eliminate any advantages of our approach or prevent us from successfully implementing our business strategy.

•: Our future growth will depend in large part on our ability to successfully develop, obtain regulatory approval (where required) for, and commercialize our product candidates and those products developed in collaboration with other companies.
•: The commercial success of our products will depend primarily on achieving market acceptance among consumers and the medical community.
•: We may be unable to develop, obtain regulatory approval where required and commercialize our product candidates as anticipated if the third parties with which we contract for pre-clinical studies, clinical trials, commercialization and marketing do not perform in an acceptable manner, or if we suffer setbacks in these clinical trials.
•: Our success is dependent in part on obtaining, maintaining and enforcing patent and other intellectual property rights. We currently have 27 patent applications pending in the United States of which eight are currently undergoing active examination. Six of those applications have received substantive actions from the United States Patent and Trademark Office and appropriate responses have been or will be filed. One of these applications, directed to our proprietary drying process, is on appeal in an attempt to obtain broad coverage. The remaining two applications undergoing active examination have received requirements to split up the claimed inventions into separate patent applications. Our competitors may create or use methods that reduce or eliminate certain competitive advantages we may have based on our intellectual property portfolio. We are subject to substantial risks relating to protection of proprietary information, infringement of rights of others and potential litigation.
•: We currently manufacture all of our products at our sole commercial manufacturing facility. Accordingly, we face risks inherent in operating a single manufacturing facility since any disruption could significantly interrupt our manufacturing capability.
•: As of December 31, 2006, we had an accumulated deficit of approximately $24.6 million and total members' equity of $25.3 million. We expect to incur additional losses and we may never be profitable.

These and other risks of which you should be aware before you decide to buy our common stock are discussed more fully in the section of this prospectus entitled "Risk Factors."

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below and all of the other information set forth in this prospectus and the registration statement before deciding to invest in shares of our common stock. If any of the events or developments described below occur, our business, financial condition or results of operations could be negatively affected. In that case, the trading price of our common stock could decline, and you could lose all or part of your investment in our common stock.

Risks Related to Our Business and Industry

We have a history of net losses and may not achieve or maintain profitability.

We were recently organized and have a limited history of operations and earnings. Since our inception in January 2004, we have experienced significant net losses. We had a net loss of approximately $3.6 million for the year ended December 31, 2004, $8.3 million for the year ended December 31, 2005 and $12.8 million for the year ended December 31, 2006. As of December 31, 2006, we had an accumulated deficit of approximately $24.6 million and total members' equity of $25.3 million. On a pro forma basis giving account to the merger of Monosol Rx LLC into MonoSol Rx, Inc. our net loss and our accumulated deficit for the year ended December 31, 2006 would have been $ million and $ million, respectively. Our losses have resulted principally from expenses incurred in developing and administering our business and infrastructure, and costs associated with research and development of our technologies. Our losses may increase in the future as we expand our manufacturing capabilities, incur additional costs related to our research and development activities, and seek additional regulatory approvals. These losses, among other things, have had and will continue to have an adverse effect on our working capital, total assets and owners' equity. We have historically experienced considerable quarter-to-quarter variation in our results of operations and may not generate sufficient revenues from product sales to achieve or maintain profitable operations in the future. If we are unable to reduce our annual losses and achieve profitability, the value of our common stock will decline.

We may not be able to successfully develop and commercialize our product candidates.

Our future growth will depend in large part on our ability to successfully develop, obtain regulatory approval for, and commercialize our product candidates and those products developed in collaboration with other companies. In many instances, we will have to conduct significant additional pre-clinical and/or clinical studies with respect to these product candidates, and may need to obtain regulatory approval before we can commercialize them. Unexpected results or delays in our clinical trials may result in increased development costs. In addition, if one or more of our clinical trials are delayed, our competitors may be able to bring products to market before we do, and the commercial viability of our product candidates could be significantly impaired.

Product development is a long, expensive and uncertain process and, in some cases, entails both pre-clinical testing, which consists of laboratory testing using biological, chemical and animal models, and human clinical testing.

We may suffer significant setbacks any time during the drug development process, even in advanced clinical trials, after obtaining promising results in earlier studies. At any point during clinical trials, undesirable side effects could be detected or the products may not exhibit the anticipated efficacy profile. These side effects and/or efficacy profiles could interrupt, delay or halt clinical trials of the product candidate being tested as well as related product candidates, and could result in the Food and Drug Administration, or FDA, or other regulatory authorities denying approval of such product candidates for any or all targeted indications.

We may be required to conduct clinical studies in pediatric patient populations as a requirement for approval or as a post-market condition of approval. Pediatric studies can be difficult to conduct and can be quite costly and may not yield the anticipated results.

Based on results at any stage of product development, we may decide to repeat or redesign pre-clinical studies or clinical trials, conduct entirely new studies or discontinue development of one or more of our product candidates. In addition, our product candidates may not demonstrate sufficient safety and efficacy in pending or any future pre-clinical testing or clinical trials to meet regulatory standards or obtain the requisite regulatory approvals, and even if such approvals are obtained for a product candidate, it may never become a viable commercial product.

If our products do not achieve market acceptance we will be unable to generate significant revenues from them.

The commercial success of our products will depend primarily on achieving market acceptance among consumers and the medical community. To accomplish this, we, together with our collaborators, will have to convince physicians, patients, third party payors and other healthcare professionals that our products consistently offer benefits that are comparable to or superior to existing products and have acceptable safety profiles and costs. If we are not successful in these efforts, market acceptance of our products could be limited, if at all. Additionally, we do not have long-term safety data for many of our products. If long-term patient studies suggest that the use of our products or similar products produced by others are associated with adverse side effects, our products may not achieve market acceptance. Even if we demonstrate the safety and effectiveness of our products, the medical community and consumers may prefer already accepted products based upon established delivery technologies or competing new technologies. Additional factors that may influence market acceptance of our products include:

•: convenience and ease of use;
•: availability of alternative and competing products or therapies;
•: effectiveness of our or our collaborators' marketing, distribution and pricing strategies; and
•: publicity concerning our products as well as our competitors' products.

If, due to any of these factors, our products do not achieve broad market acceptance, we will be unable to generate significant revenues from them, which would have a material adverse effect on our business, cash flows and results of operations.

If the third parties with which we contract for pre-clinical studies, clinical trials, commercialization, and marketing do not perform in an acceptable manner, or if we suffer setbacks in these clinical trials, we may be unable to develop, obtain regulatory approval where required and commercialize our product candidates as anticipated.

We will, from time to time, after a quality review and assessment of their capabilities, engage and rely on third parties, contract research organizations and outside consultants to assist us in managing and monitoring our pre-clinical studies, clinical trials, obtaining regulatory approval, commercialization efforts, and marketing strategies. If any of these parties terminates their agreements with us, the development of the product candidates covered by those agreements could be substantially delayed. In addition, these third parties may not successfully carry out their contractual obligations, meet expected deadlines or follow regulatory requirements, including clinical, laboratory and manufacturing guidelines. We may also develop conflicting priorities or other conflicts of interest with our strategic partners. Our reliance on these third parties may result in increased costs and delays in completing, or in failing to complete, the testing, obtaining regulatory approval when required, and commercialization of our products. If clinical testing of our product candidates is compromised for any of the above-mentioned

reasons, we will be unable to meet our anticipated development or commercialization timelines, which would have a material adverse effect on our business.

If the suppliers on which we rely fail to supply us with the raw materials and other components we use in manufacturing our products, we may be unable to satisfy product demand.

We depend on third parties for the supply of certain ingredients we use to produce our products. While many of these ingredients are available from multiple suppliers, some are available from only one supplier without the benefit of long-term supply agreements.

Our reliance on these suppliers exposes us to significant risks. These third parties may:

•: be unable or unwilling to provide us with sufficient materials to meet our demands;
•: fail to meet our standards of quality or other specifications;
•: fail to meet current good manufacturing practices, or cGMP;
•: increase significantly the prices they charge us for materials; or
•: not carry out their contractual duties or meet anticipated deadlines, which could result in delays in obtaining or maintaining regulatory approvals or in satisfying customer orders.

If our suppliers are unwilling or unable to supply us with materials meeting our specifications, we may not be able to locate any alternative suppliers or enter into commercially reasonable agreements with suppliers in a timely manner or at all. Even if we are able to locate, qualify and enter into an agreement with new suppliers, it could take several months or longer to obtain regulatory clearance before a new supplier could begin supplying the relevant product to us. If we are delayed in establishing a secondary supply source for any raw material or component that we purchase from a single source, or cannot do so at an acceptable cost, we may suffer a shortage of commercial supply of that product or a higher cost of procuring the product, either of which would have a material adverse effect on our revenues, business and financial prospects.

A disruption at our sole manufacturing site would significantly interrupt our production capabilities, which could have drastic consequences to us, including threatening our financial viability.

We currently manufacture all of our products at our sole commercial manufacturing facility, which is located in Portage, Indiana. Accordingly, we face risks inherent in operating a single manufacturing facility since any disruption, such as a fire, natural disaster, terrorist attack or military action, could significantly interrupt our manufacturing capability. If an inspection by the FDA or other regulatory body identifies significant regulatory issues with respect to our compliance with cGMP, this also could have a material adverse impact on our ability to manufacture products for commercial distribution. Should this occur, we cannot provide any assurance concerning our ability to timely respond to such inspectional observations and the time it would take the FDA or other regulatory body to re-inspect our facility. This could adversely affect the time to approval and our ability to produce products for the commercial market. We currently do not have alternative production plans in place or disaster-recovery facilities available. In case of a disruption, we will have to establish alternative manufacturing sources. This would require substantial capital on our part, which we may not be able to obtain on commercially acceptable terms or at all. Additionally, we would likely experience months or years of production delays as we build or locate replacement facilities and seek and obtain necessary regulatory approvals. If this occurs, we will be unable to satisfy customer orders on a timely basis, if at all. In addition, a disruption at our sole manufacturing site may impair or delay our ability to meet product demands from our customers. Also, operating any new facilities may be more expensive than operating our current facility. Furthermore, our business interruption insurance may not adequately compensate us for losses that may occur and we would have to bear the additional cost of any disruption. For these

reasons, a significant disruptive event at our manufacturing facility could have drastic consequences on us, including threatening our financial viability.

If we are unable to expand our manufacturing capacity as planned, we may be unable to satisfy demand for our products.

We need to expand our manufacturing capacity to meet anticipated demand for our products. In October 2006, we entered into an agreement to lease a 73,000 square foot facility in Portage, Indiana, the Ameriplex facility. We took possession of this facility in April 2007. The Ameriplex facility will become our primary research, development and manufacturing facility once it is retrofitted and occupied. We anticipate relocating our production and packaging equipment to the Ameriplex facility while we continue to make products for our existing customer base using such equipment. This relocation, if prolonged, could cause interruptions in our ability to make products, and our business could be adversely affected as a result. We may not be able to obtain the requisite regulatory approvals for the Ameriplex facility on a timely basis, or at all, and while we believe that the Ameriplex facility will be completed in phases through 2007 and the first half of 2008, we may not be able to complete the expansion of this facility within our anticipated time frame or budget. Even if we complete the construction in a timely manner, we may not be able to obtain the requisite regulatory approvals for the facility on a timely basis, or at all. If we cannot obtain necessary approvals for these contemplated expansions, or complete the planned construction in a timely manner, our ability to meet demand for our products would be adversely affected.

We may not achieve our projected development goals in the time frames we announce and expect.

We set goals for and make public statements regarding expected timing for the accomplishment of objectives material to our success, such as the commencement and completion of clinical trials. The actual timing of these events can vary dramatically due to factors such as delays or failures in our clinical trials, the uncertainties inherent in the regulatory approval process and delays in achieving manufacturing or marketing arrangements sufficient to commercialize our products. There can be no assurance that our product development will be completed, that we will make regulatory submissions or receive regulatory approvals as planned, or that we will be able to adhere to our current schedule for the launch of any of our products. If we fail to achieve one or more of these milestones as planned, the market price of our shares could decline.

We may not be able to obtain additional capital that may be necessary for growth and market penetration or to continue our operations.

The core of our strategy involves the development of our thin film drug delivery technology to targeted prescription pharmaceuticals. This area of product development is a multi-year process that requires formulation, stability, validation and analytical testing, clinical studies and necessary regulatory approvals prior to realizing any product revenue. We may need to raise additional funds through public or private debt or equity financings in order to develop or acquire new products or new product candidates, expand our manufacturing capacity, establish and expand our sales and marketing capabilities, obtain FDA approval for our product candidates and continue our commercial growth. Any additional equity financings may be on terms that are dilutive to our stockholders. Any debt financings we enter into may involve incurring significant interest expense and include covenants that restrict our operations. If we raise additional funds through collaborations or licensing arrangements, it may be necessary to relinquish some rights to our technologies, product candidates or products, or grant licenses on terms that are not favorable to us. Our ability to raise additional funds will depend on financial, economic, and market conditions and other factors, many of which are beyond our control. We may not be able to obtain financing on terms acceptable to us or at all. If financing is insufficient or unavailable, we will have to modify our growth and marketing strategies and scale back operations by delaying, reducing the scope of, or eliminating one or more of our planned developments,

commercialization, or expansion activities. This may negatively affect the commercial expansion of our existing products and our ability to bring new over-the-counter, or OTC, and prescription pharmaceutical products to market, which could have a material adverse effect on our business, financial condition and results of operations.

Our future need for additional funds may be significantly greater than we expect, and will depend on many factors, including:

•: costs associated with conducting pre-clinical testing and clinical testing;
•: costs associated with commercializing products we may develop;
•: costs, timing and outcome of regulatory reviews;
•: costs of obtaining, maintaining and defending patents on proprietary technology;
•: costs of increased general and administrative activities; and
•: costs associated with retrofitting our Ameriplex facility.

If our partners terminate their relationships with us it could result in decreased revenues and material harm to our business.

Our contracts for the development of thin film drug candidates generally allow our customers to terminate development or elect to not commercialize a candidate that is developed for thin film. Our partners could terminate development or not commercialize due to technical difficulties, issues with commercial acceptance, costs, regulatory barriers and other concerns. Such outcomes could have a material adverse effect on our business, financial condition and results of operations.

Additionally, our relationship with some of our partners is on a purchase order basis and it is possible for these partners to discontinue placing product orders with us and thus terminate the relationship. This may impact our results of operations and future revenues.

We may encounter difficulties managing our growth, which could adversely affect our results of operations.

In connection with the growth of our business, we may experience rapid and significant growth in the number of our employees and the scope of our operations. Our future financial performance and our ability to commercialize our products and to compete effectively will depend, in part, on our ability to manage any future growth effectively. This growth and expansion is expected to place a significant demand on our financial, managerial and operational resources, and will require rapid analysis of new technologies, new markets, and new business relationships with a variety of industry players. Rapid growth, or mismanagement of such growth, could cause our operating costs to rise at a faster pace than is currently anticipated and could have a material adverse effect on our business, financial condition and results of operations.

Disputes may arise involving the contractual obligations of our partners to purchase our products or pay royalties on the sale of our products, and such disputes, if not resolved in our favor, could result in decreased revenues and material harm to our business.

Disputes may arise between us and our partners and may involve the issue of the obligation to continue to purchase our products and pay royalties on the sale of our products. Such a dispute could result in expensive arbitration or litigation, which may not be resolved in our favor, or the termination of our relationship with the partner.

If our competitors develop and market products faster than we do or if those products are less expensive or more effective than our products, our commercial opportunities will be reduced or eliminated.

The drug delivery, biotechnology, and pharmaceutical industries are characterized by intense competition and rapidly evolving technology. Our competitors have longer operating histories than we do, greater name recognition, and significantly greater resources and expertise in product development, regulatory matters, finance, marketing and sales. These organizations also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials and acquiring and licensing technologies. As a result, these competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements. Competitors may use their extensive resources to develop products that are more effective, safer, more convenient or less costly than any that we are developing.

If we lose the services of our key management, scientific personnel or scientific collaborators, our business would suffer.

The success of our business is highly dependent on our management as well as our senior manufacturing and scientific personnel. In addition, we require additional skilled personnel in areas such as business and clinical development. We do not maintain key-person life insurance on any of our officers, employees or consultants. While we do have employment agreements and other retention inducements with certain key employees and consultants, those agreements do not prevent employees from leaving us to pursue other non-competing interests. The pool of individuals with relevant experience in the thin film drug delivery technology industry is very limited, and retaining and training personnel with the skills necessary to operate our business effectively is challenging, costly and time consuming. If we lose the services of any key personnel, our business, financial condition and results of operations could be materially and adversely affected.

If product liability lawsuits are brought against us as a result of, for example, product recalls, or serious, unexpected adverse events, we may incur substantial liabilities and could be required to limit the commercialization of our products.

We are exposed to the risk of product liability claims inherent in businesses that test, manufacture, market and sell pharmaceutical products. We may be subject to claims against us even if the injury is due to the actions of others.

If we are involved in any product liability litigation, such litigation would consume substantial amounts of our financial and managerial resources and may result in adverse publicity regardless of the ultimate outcome of the litigation, decreased demand for our product candidates, withdrawal of clinical trial participants, significant litigation costs and substantial monetary awards to, or costs of settlement with, patients, product recalls and loss of revenues, and the inability to commercialize our product candidates. Although we believe we have appropriate insurance coverage, we may not be able to maintain our clinical trial insurance or product liability insurance at an acceptable cost or at all. In any event, liability insurance is subject to deductibles and coverage limitations and may not provide adequate coverage against potential claims or losses. A successful product liability claim brought against us could cause us to incur substantial liabilities.

If we or others identify serious adverse events after any of our products are on the market, we may be required to withdraw our products from the market, which would hinder or preclude our ability to generate revenues.

If we or others identify serious, adverse events after any of our products are on the market:

•: regulatory authorities may withdraw their approvals;
•: we may be required to reformulate our products;

•: we may have to recall the affected products from the market and may not be able to reintroduce them onto the market;
•: our reputation in the marketplace may suffer; and
•: we may become the target of lawsuits, including class action suits.

Any of these events could harm or prevent sales of the affected products or could substantially increase the costs and expenses of commercializing or marketing these products.

Our operations involve hazardous materials that may cause injury for which we could be liable for damages.

Our manufacturing and research and development activities sometimes involve the controlled use and disposal of potentially hazardous materials or controlled substances and chemicals. As such, we are subject to various environmental, health and safety laws and regulations, including those governing air emissions, water and wastewater discharges, noise emissions, the use, management and disposal of hazardous, radioactive and biological materials and wastes, and the cleanup of contaminated sites. The cost of compliance with these laws and regulations could be significant and accidental contamination or injury may occur. Although we believe that our safety and control procedures for handling, storing and disposing of such materials comply with the standards prescribed by applicable regulations, we cannot completely eliminate the risk of contamination or injury from use or mishandling of these materials. We also occasionally contract with third parties for the disposal of some of these materials. In addition, our collaborators and service providers may be working with these types of materials in connection with our collaborations. In the event of an accident or contamination, we could be held responsible for any injury caused to persons or property by exposure to, or release of, these materials and could be held liable for significant damages, civil penalties or fines, which may not be covered by or may exceed our insurance coverage.

Additionally, we are subject on an ongoing basis to a variety of laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of continued compliance with current or new laws and regulations may be significant and could negatively affect our profitability, and current or future environmental regulation may impair our ongoing research, development or manufacturing efforts.

Risks Related to Our Intellectual Property

The validity, enforceability and commercial value of our intellectual property rights are highly uncertain.

Our success is dependent in part on obtaining, maintaining and enforcing patent and other intellectual property rights. We seek to obtain and maintain patents and other intellectual property rights to restrict the ability of others to market products that compete with our products. We currently have 27 patent applications pending in the U.S. of which eight are currently undergoing active examination. Six of these applications have received substantive actions from the United States Patent and Trademark Office and appropriate responses have been or will be filed. One of these applications, directed to our proprietary drying process, is on appeal in an attempt to obtain broad coverage. The remaining two of the applications undergoing active examination in the U.S. have received requirements to split up the claimed inventions into separate patent applications. Because of the many complex legal and technical issues involved, the patent position of pharmaceutical firms is highly uncertain. The process for obtaining a patent in the U.S. involves a number of varying factors, including the subjectivity inherent in the normal examination process. Such factors may make it difficult to obtain the issuance of a patent or a patent with scope that is competetively meaningful. Patent applications we file or license from others may not result in the issuance of a patent. The U.S. Supreme Court's recent decision in KSR International v. Teleflex Inc. may make it more difficult to be granted certain patents. Moreover, although issued patents in the U.S. enjoy the pressumption of

validity, this may be challenged and potentially overturned as the result of litigation. Patents, if issued, may be challenged and invalidated altogether, substantially narrowed as to scope or determined to be unenforceable. Consequently, it is not entirely certain how much protection, if any, patents will provide to us if we attempt to enforce them.

Patent rights are territorial. Thus, the patent protection we do have will only extend to those countries in which we have issued patents. Even so, the laws of certain countries do not protect our intellectual property rights to the same extent as do the laws of the United States and various European countries. Competitors may successfully challenge our patents, produce similar drugs or products that do not infringe our patents, or produce drugs in countries where we have not applied for patent protection or that do not respect our patents. Additionally, the nature of claims contained in unpublished patent filings around the world is unknown to us and it is not possible to know which countries patent holders may choose for the extension of their filings under the Patent Cooperation Treaty, or other mechanisms. Furthermore, it is not possible to know the scope of claims that will be allowed in published applications and it is also not possible to know which claims of granted patents, if any, will be deemed enforceable in a court of law.

Our patents, if issued, may not contain claims that are sufficiently broad to prevent others from practicing our technologies or developing competing products. Our competitors may create or use methods that reduce or eliminate any competitive advantage we may have based on our thin film development intellectual property portfolio. Additionally, technologies may exist that perform substantially the same as our technologies and avoid infringing our patent claims. Under such circumstances, our patents would be of little commercial value to us.

We may not be able, alone or with our collaborators and licensors, to prevent misappropriation of our proprietary rights, particularly in countries where the laws may not protect such rights as fully as in the United States. Thus, any patents that we own or license from third parties may not provide commercially meaningful protection from competition.

If we are unable to protect the confidentiality of our trade secrets or know how, such proprietary information may be used by others to compete against us.

We have concluded that certain competitively sensitive information is either not patentable or, for competitive reasons, it is not commercially advantageous to seek patent protection. In these circumstances, we seek to protect this know how and other proprietary information by maintaining it in confidence as a trade secret. Trade secret information is closely guarded and areas involving trade secrets have restricted access. To further maintain the confidentiality of our trade secrets, we generally enter into confidentiality agreements with our employees, consultants and collaborators upon the commencement of their relationships with us. These agreements require that all confidential information developed by the individual or made known to the individual by us during the course of the individual's relationship with us be kept confidential and not disclosed to third parties. Our agreements with employees also provide that inventions conceived by the individual in the course of rendering services to us shall be our exclusive property. However, we may not obtain these agreements in all circumstances, and individuals with whom we have these agreements may not comply with the terms of these agreements. The disclosure of our trade secrets would impair our competitive position. Adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information. Further, to the extent that our employees, consultants or contractors use trade secret technology or know how owned by others in their work for us, disputes may arise as to the ownership of related inventions.

Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties.

In the event that our technologies infringe or violate the patent or other proprietary rights of third parties, we may be prevented from pursuing product development, manufacturing or commercialization of our products that utilize such technologies. There may be patents held by others of which we are unaware that contain claims that our products or operations infringe. In addition, given the complexities and uncertainties of patent laws, there may be patents of which we know that we may ultimately be held to infringe, particularly if the claims of the patent are determined to be broader than we believe them to be. Adding to this uncertainty, in the United States, patent applications filed in recent years are confidential for 18 months, while older applications are not publicly available until the patent issues. As a result, avoiding patent infringement may be difficult.

If a third party claims that we infringe its patents, any of the following may occur:

•: we may become liable for substantial damages for past infringement if a court decides that our technologies infringe upon a competitor's patent;
•: a court may prohibit us from selling or licensing our product without a license from the patent holder, which may not be available on commercially acceptable terms or at all, or which may require us to pay substantial royalties or grant cross-licenses to our patents; or
•: we may have to redesign our product so that it does not infringe upon others' patent rights, which may not be possible or could require substantial funds or time.

In addition, employees, consultants, contractors and others may use the trade secret information of others in their work for us or disclose our trade secret information to others. Either of these events could lead to disputes over the ownership of inventions derived from that information or expose us to potential damages or other penalties. If any of these events occurs, our business will suffer and the market price of our common stock will likely decline.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights.

There has been substantial litigation and other proceedings regarding patent and intellectual property rights in the pharmaceutical industry. We may be forced to defend claims of infringement brought by our competitors and others, and we may institute litigation against others who we believe are infringing our intellectual property rights. The outcome of intellectual property litigation is subject to substantial uncertainties and may, for example, turn on the interpretation of claim language by the court, which may not be to our advantage, or on the testimony of experts as to technical facts upon which experts may reasonably disagree. Our involvement in intellectual property litigation could result in significant expense to us. Some of our competitors have considerable resources available to them and a strong economic incentive to undertake substantial efforts to stop or delay us from commercializing products. We, on the other hand, are a relatively small company with comparatively few resources available to us to engage in costly and protracted litigation. Moreover, regardless of the outcome, intellectual property litigation against or by us could significantly disrupt our development and commercialization efforts, divert our management's attention and quickly consume our financial resources.

Furthermore, the validity and scope of our patents may also be challenged by third parties in re-examination proceedings at the U.S. Patent and Trademark Office, which may either strengthen a patent, or result in a reduced claim scope or a loss of all rights to a patent.

In addition, if third parties file patent applications or issue patents claiming technology that is also claimed by us in pending applications, we may be required to participate in interference proceedings with the U.S. Patent and Trademark Office or in other proceedings outside the United States, including oppositions, to determine priority of invention or patentability. Even if we are successful in these proceedings, we may incur substantial costs, and the time and attention of our management and scientific personnel will be diverted in pursuit of these proceedings.

As a result of patent infringement claims, or to avoid potential claims, we may choose or be required to seek a license from a third party and would most likely be required to pay license fees or royalties or both. These licenses may not be available on acceptable terms, or at all. Even if we were able to obtain a license, the rights may be non-exclusive, which could potentially limit our competitive advantage. Ultimately, we could be prevented from commercializing a product or be forced to cease some aspect of our business operations if, as a result of actual or threatened patent infringement claims, we are unable to enter into licenses on acceptable terms. This inability to enter into licenses could harm our business significantly. At present, we have not received any threats of infringement or written demands from third parties that we take a license under their patents.

Risks Related to Government Regulation

Our products are subject to regulation by many federal, state, and local agencies, and our customers may require that we obtain certain regulatory approvals before purchasing our products.

Many of our products are still under development, and we and/or our collaborating partners may not be able to commercialize these products until we comply with the requirements of federal, state and local regulatory authorities including the FDA, the Federal Trade Commission, or FTC, the Consumer Product Safety Commission, the U.S. Environmental Protection Agency, and various state and local agencies. In particular, the process of obtaining FDA approval for new drug products (including new dosage forms of previously approved drug products) can be costly and time-consuming, and the time required for obtaining such approval is uncertain. In addition, while the FDA has not made any definitive rulings on the regulatory status of film-based drug delivery systems, the FDA and state and local agencies could impose significant regulatory requirements on our products. Additionally, our customers may require that we obtain such approvals prior to licensing or purchasing our products. If the FDA or our customers require that we obtain regulatory approval of our products, we or our collaboration partners must demonstrate to the satisfaction of the applicable regulatory agency that such product candidate is safe and effective for its intended uses. In addition, we must show that the product can be consistently manufactured in compliance with cGMP. In general, these requirements mandate that manufacturers follow detailed design, testing, control, documentation and other quality assurance procedures throughout the entire manufacturing process. We can give no assurance that despite the time, expense, and resources invested by us in the approval process, we may not be able to demonstrate that our product candidates are safe and effective, in which event we would not receive the regulatory approvals required to market them, our current or future product candidates will be approved by the FDA or any other governmental body, or that FDA or other governmental reviews will not involve delays caused by requests for further testing or other information that could adversely affect the time to market for our products.

Moreover, we cannot predict the impact of new government regulations that may adversely affect the discovery, development and production of our product candidates and the manufacturing and marketing of our products. We may be required to incur significant costs to comply with future laws or regulations.

Our product candidates will remain subject to ongoing regulatory requirements if they receive regulatory approval for marketing, and if we fail to comply with these requirements, we could lose these approvals, and the sales of any approved commercial products could be suspended.

After receipt of initial regulatory approval, each of our products remains subject to extensive regulatory requirements, including requirements relating to manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, distribution and record-keeping. Furthermore, if we receive regulatory approval to market a particular product candidate, the product will also remain subject to the same extensive regulatory requirements. Even if regulatory approval of a product is granted, the approval may be subject to limitations on the uses for which the product may be marketed

or other conditions of approval, or contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product, which could reduce our revenues, increase our expenses or render the approved product candidate not commercially viable.

If we or our partners fail to comply with the regulatory requirements of the FDA or other applicable regulatory authorities, or if previously unknown problems with any approved commercial products, manufacturers or manufacturing process are discovered, we could be subject to administrative or judicially imposed sanctions or other setbacks, including:

•: restrictions on the products, manufacturers or manufacturing processes;
•: warning letters and untitled letters;
•: civil penalties and criminal prosecutions and penalties;
•: fines;
•: injunctions;
•: product seizures or detentions;
•: import or export bans or restrictions;
•: voluntary or mandatory product recalls and related publicity requirements;
•: suspension or withdrawal of regulatory approvals;
•: total or partial suspension of production; and
•: refusal to approve pending applications for marketing approval of new products or of supplements to approved applications.

If we and our third-party suppliers do not maintain high standards of manufacturing in accordance with cGMP and other manufacturing regulations, our development and commercialization activities could suffer significant interruptions or delays.

We and any third-party suppliers on which we may in the future rely will be required to comply with cGMP. In complying with these regulations, we and our third-party suppliers may be required to expend significant time, money and effort in the areas of design and development, testing, production, record-keeping and quality control to assure that our products meet applicable specifications and other regulatory requirements. Failure to comply with these or other regulatory requirements could result in an enforcement action against us, including the seizure of products and shutting down of production. Any of these third-party suppliers and we also may be subject to periodic inspections by the FDA and other regulatory agencies. If any of our third-party suppliers or we fail to comply with cGMP or other applicable manufacturing regulations, our ability to develop and commercialize our products could suffer significant interruptions.

We must comply with the laws, regulations and rules of many jurisdictions relating to the healthcare business, and if we are unable to fully comply with such laws, regulations and other rules, we could face substantial penalties.

We are or will be, directly or indirectly through our customers, subject to extensive regulation by the various jurisdictions in which we may conduct our business. The laws that directly or indirectly affect our ability to operate our business include the following:

•: the anti-kickback laws that prohibit persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce either the referral of an individual, or the furnishing or arranging for a good or service, for which

payment may be made under federal healthcare programs such as Medicare and Medicaid in the United States;

•: other healthcare laws, including Medicare laws in the United States, regulations, rules, manual provisions and policies that prescribe the requirements for coverage and payment for services performed by our customers, including the amount of such payment;
•: laws and regulations, including the U.S. False Claims Act, which impose civil and criminal liability on individuals and entities who submit, or cause to be submitted, false or fraudulent claims for payment to the government;
•: laws and regulations, including the U.S. False Statements Act, which prohibit knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services; and
•: state law equivalents and comparable laws in countries outside of the United States, including laws regarding pharmaceutical company marketing compliance, reporting and disclosure obligations.

If our operations are found to be in violation of any of the laws, regulations, rules or policies described above or any other law or governmental regulation to which we or our customers are or will be subject, or if the interpretation of such laws, regulations, rules or policies change, we may be subject to civil and criminal penalties, damages, fines, exclusion from the Medicare and Medicaid programs and curtailment or restructuring of our operations. Similarly, if our customers are found noncompliant with applicable laws, they may be subject to sanctions, which could negatively impact us. Any penalties, damages, fines, curtailment or restructuring of our operations would harm our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that many such laws have not been fully interpreted by the regulatory authorities or the courts, and their provisions may be open to a variety of interpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert management resources from the operation of our business and damage our reputation.

Risks Related to this Offering and Our Common Stock

There is no established trading market for our common stock, and the price of our common stock may be highly volatile or may decline regardless of our operating performance.

Prior to this offering, there has been no public market for our common stock. We cannot predict the extent to which a trading market for our common stock will develop or be sustained after this offering. The initial public offering price will be determined by negotiations between us and the representatives of the underwriters, based on factors that may not be indicative of future performance, and may not bear any relationship to the price at which our common stock will trade upon completion of this offering. You may be unable to sell your shares of common stock at or above the initial public offering price.

The initial public offering price was determined based on several factors which are summarized in the "Underwriting" section of this prospectus. This price may vary from the market price of our common stock after this offering. You may be unable to sell your shares of common stock at or above the initial offering price. The stock market, particularly in recent years, has experienced significant volatility particularly with respect to pharmaceutical and biotechnology stocks, collectively, biopharmaceutical stocks. The volatility of biopharmaceutical stocks often does not relate to the operating performance of the companies represented by the shares.

The trading price of our common stock could be highly volatile in response to various factors, many of which are beyond our control, including:

•: changes in the regulatory climate in the biopharmaceutical industry;
•: developments concerning our products or any of our product candidates;
•: the timing and results from our clinical trial programs or those of our competitors;
•: failure of any of our product candidates, if approved, to achieve commercial success;
•: new products introduced or announced by us or our competitors;
•: announcements of technological innovations by us or our competitors;
•: third-party reimbursement policies;
•: developments concerning current or future strategic alliances;
•: expiration or termination of licenses, research contracts or other collaboration agreements;
•: intellectual property, product liability or other litigation against us;
•: market conditions in the biopharmaceutical sector;
•: changes in the market valuations of similar companies;
•: actual or anticipated variations in our operating results;
•: deviations in our operating results from the estimates of securities analysts;
•: additions or departures of key personnel; and
•: sales of shares of our common stock, particularly sales by our officers, directors and significant stockholders.

In addition, equity markets in general, and the market for small pharmaceutical companies in particular, have experienced substantial price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies traded in those markets. Changes in economic conditions in the United States or globally could also impact our ability to grow profitably. These broad market and industry factors may materially affect the market price of our common stock, regardless of our business or operating performance. In the past, following periods of volatility in the market price of a company's securities, securities class-action litigation has often been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management's attention and resources, which could have a material adverse effect on our business, financial condition and results of operations.

The ownership interests of our officers, directors and largest stockholders could conflict with the interests of our other stockholders.

Following the completion of this offering, our directors, executive officers and holders of 5% or more of our outstanding common stock will beneficially own approximately % of our common stock. In particular, MRX Partners, LLC, MonoLine RX, L.P., MonoLine RX II, L.P. and Monosol RX Genpar, L.P., all of which are under common control, will own %, %, % and %, respectively, for a total of %. Additionally, Halifax Monosol Investors, L.P. will own % of our common stock. As a result, our directors, executive officers and holders of 5% or more of our outstanding common stock, acting together, or MRX Partners, LLC, MonoLine RX, L.P., MonoLine RX II, L.P. and Halifax MonoSol Investors, L.P., may be able to significantly influence all matters requiring approval by our stockholders, including the election of directors and approval of mergers or other significant corporate transactions. The interests of this group of stockholders may not always

coincide with our interests or the interests of other stockholders. This concentration of ownership could also have the effect of delaying, deferring or preventing a change in our control or impeding a merger or consolidation, takeover or other business combination that could be favorable to you.

We have broad discretion in the use of the proceeds from this offering and our use of the offering proceeds may not yield a favorable return on your investment.

We expect to use proceeds from this offering for the development of prescription drug targets on thin film and other self-funded initiatives, including product development, clinical trials and submissions for new drug applications, or NDAs, 505(b)(2) applications, or 505(b)(2), supplemental new drug applications, or sNDAs, and abbreviated new drug applications, or ANDAs, operating expenditures and infrastructure, capital expenditures, and other general corporate purposes. However, our management has broad discretion over how these proceeds are used and could spend the proceeds in ways with which you may not agree. We may not invest the proceeds of this offering effectively or in a manner that yields a favorable or any return, and consequently, this could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline or delay the development of our product candidates.

We have never paid dividends on our common stock, and we do not anticipate paying dividends in the foreseeable future.

We have paid no dividends to date, and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. As a result, we do not expect to pay any dividends in the foreseeable future. Any future payment of dividends, if any, will also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. Furthermore, we may in the future become subject to contractual restrictions on, or prohibitions against, the payment of dividends. Accordingly, the success of your investment in our common stock will likely depend entirely upon any future appreciation. There is no guarantee that our common stock will appreciate in value after the offering or even maintain the price at which you purchased your shares, and you may not realize a return on your investment in our common stock.

Investors in this offering will pay a much higher price than the book value of our common stock.

If you purchase common stock in this offering, you will pay more for your shares than the amounts paid by existing stockholders for their shares. The price per share you will pay will also substantially exceed the book value of our assets represented by your shares of common stock after subtracting related liabilities. You will incur immediate and substantial dilution of $ per share, representing the difference between our pro forma net tangible book value per share after giving effect to this offering and the initial public offering price of $ per share. Upon completion of this initial public offering, the new public investors will have contributed % of the total amount of capital used to fund us to date, and will own % of the common stock outstanding after this offering.

If an active, liquid trading market for our common stock does not develop, you may be unable to sell your shares quickly or at the market price.

Prior to this offering, you could not buy or sell our common stock publicly. An active trading market for our common stock may not develop or be sustained after this offering. You may not be able to sell your shares quickly or at the market price if trading in our stock is not active.

Certain provisions of Delaware law and our organizational documents could delay or discourage takeover attempts that stockholders may consider favorable.

Certain provisions of our certificate of incorporation and bylaws and applicable provisions of Delaware corporate law may make it more difficult for or prevent a third party from acquiring control of us or changing our board of directors and management. These provisions:

•: allow the authorized number of directors to be changed only by resolution of our board of directors;
•: allow our board of directors to designate the terms of and issue, without stockholder approval, series of preferred stock with voting or other rights or preferences that could operate to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that is not approved by our board of directors;
•: limit stockholder action by written consent;
•: limit who may call meetings of our stockholders; and
•: require our stockholders to comply with advance notice procedures to nominate candidates for election to our board of directors or to place stockholders' proposals on the agenda for consideration at meetings of stockholders.

In addition, Section 203 of the Delaware General Corporation Law, or DGCL, generally prohibits us from engaging in any business combination with certain persons who own 15% or more of our outstanding voting stock without the approval of our board of directors. These provisions could make it difficult for a third party to acquire us, or for members of our board of directors to be replaced, even if doing so would be beneficial to our stockholders. Any delay or prevention of a change in control transaction or changes in our board of directors or management could deter potential acquirers or prevent the completion of a transaction in which our stockholders could receive a substantial premium over the then-current market price for their shares.

Future sales of our common stock may cause the market price of our common stock to fall.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell their shares, could reduce the market price of our common stock. After this offering, we will have outstanding shares of common stock. This includes the shares that we are selling in this offering, which may be resold in the public market immediately. The remaining approximately shares are currently restricted as a result of securities laws or lock-up agreements but will be able to be sold in the near future. Moreover, after the expiration of the lock-up period described in the section of this prospectus entitled "Shares Eligible for Future Sale — Lock-up Agreements" approximately shares of our common stock will be eligible for resale. We intend to register all shares of common stock that we may issue under our 2007 Stock Incentive Plan. See "Shares eligible for future sale" contained elsewhere in this prospectus.

We have never operated as a public company and fulfilling our obligations as a public company will be expensive and time consuming.

As a private company with limited resources, we have maintained a small finance and accounting staff. As a public company, the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the U.S. Securities and Exchange Commission, or SEC, as well as the rules of The Nasdaq Global Market, Inc. will require us to implement additional corporate governance practices and adhere to a variety of reporting requirements and complex accounting rules. Compliance with these public company

obligations will increase our legal and financial compliance costs and place significant additional demands on our finance and accounting staff and on our financial, accounting and information systems.

In particular, as a public company, our management will be required to conduct an annual evaluation of our internal control over financial reporting and include a report of management on our internal control in our annual reports on Form 10-K. In addition, we will be required to have our independent registered public accounting firm attest to and report on management's assessment of the effectiveness of our internal control over financial reporting. Under current rules, we will be subject to these requirements beginning with our annual report on Form 10-K for our fiscal year ending December 31, 2008. If we are unable to conclude that we have effective internal control over financial reporting or, if our independent registered public accounting firm is unable to provide us with an attestation and an unqualified report as to the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our financial statements, which could result in a decrease in the value of our common stock.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.

Effective internal control over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. If we cannot provide reliable financial reports or prevent fraud, our operating results could be harmed. We continue to evaluate our internal control over financial reporting. Given the status of our efforts, coupled with the fact that guidance from regulatory authorities in the area of internal control continues to evolve, uncertainty exists regarding our ability to comply by applicable deadlines. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock.

CORPORATE FORMATION TRANSACTION

Prior to this offering, we conducted our business through Monosol Rx LLC, a Delaware limited liability company. Immediately prior to this offering, Monosol Rx LLC will merge with and into MonoSol Rx, Inc., a newly formed Delaware corporation, the shares of which are being sold in this offering. After completion of this offering, the existing equity owners of Monosol Rx LLC, as well as the holders of the performance units of Monosol Rx LLC, will own shares of our common stock representing approximately % of the voting power of our outstanding capital stock. See "Principal Stockholders" for more information regarding the ownership of our common stock.

USE OF PROCEEDS

We will receive approximately $ million in net proceeds from the sale of our common stock in this offering, after deducting underwriting discounts and commissions and estimated offering expenses. If the underwriters exercise their overallotment option in full, we estimate that our net proceeds will be approximately $ million.

Each $1.00 increase (decrease) in the assumed initial public offering price of $ per share would increase (decrease) the net proceeds to us from this offering by $ million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We currently expect to use the net proceeds of this offering as follows:

•: approximately $ million for the development of thin film versions of existing drugs and other self-funded initiatives, including product development, clinical trials, and any necessary regulatory submissions;
•: approximately $ million for capital expenditures, including retrofitting the newly leased Ameriplex facility to create a cGMP manufacturing facility for the development and manufacture of dissolving thin film. In addition, proceeds will be used to acquire equipment to create additional laboratory and manufacturing capacity as demand increases; and
•: the remainder, approximately $ million, for working capital and other general corporate purposes, a portion of which may be used to acquire businesses, products or technologies that are complementary to our current or future business and product lines.

We believe that the net proceeds from this offering, together with our existing cash and cash equivalents, as supplemented by our research and co-development fees, will be sufficient to meet our projected operating requirements for approximately the next 24 months. The amounts and timing of our use of proceeds will vary depending on a number of factors, including the amount of cash used by our operations, and the rate of growth, if any, of our business. The allocation of the net proceeds of this offering described above represents our best current estimate of our projected operating requirements. Our management will have broad discretion in the application of the net proceeds and we reserve the right to change the use of these proceeds in response to certain contingencies such as the results of our commercialization activities, competitive developments, opportunities to acquire or license products to others, technologies or businesses and other factors.

DIVIDEND POLICY

We have not declared or paid any dividends to date. We currently intend to retain future earnings, if any, to fund the development and expansion of our business and do not anticipate paying dividends on our common stock in the foreseeable future. Any future determination to pay dividends will be at the discretion of our board of directors and will depend on a number of factors, including our financial condition, results of operations, capital requirements, restrictions contained in future financing instruments and other factors that our board of directors may deem relevant.

The following table sets forth our cash and cash equivalents, and capitalization as of December 31, 2006:

•: on an actual basis;
•: on a pro forma basis to give effect to the merger of Monosol Rx LLC into MonoSol Rx, Inc.; and
•: on a pro forma as adjusted basis to give effect to (1) the merger of Monosol Rx LLC into MonoSol Rx, Inc. and (2) the sale of the shares of common stock in this offering at an initial public offering price of $ per share, after deducting underwriting discounts and commissions and estimated offering expenses.

The table above should be read in conjunction with the "Use of Proceeds," "Selected Financial Data," "Unaudited Pro Forma Financial Statements," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and our financial statements and related notes included elsewhere in this prospectus. This table is based on 101,413,600 membership interests in Monosol Rx LLC outstanding as of December 31, 2006 and shares of our common stock outstanding on a pro forma basis as of December 31, 2006 and excludes, as of that date shares of our common stock available for future grant under our 2007 Stock Incentive Plan. See "Unaudited Pro Forma Financial Statements."

DILUTION

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the initial public offering price per share you pay in this offering and the as adjusted net tangible book value per share of our common stock immediately after this offering.

Our historical net tangible book value as of December 31, 2006 was approximately $ million, or approximately $ per share of our common stock on a pro forma basis. Net tangible book value per share is equal to our total tangible assets minus total liabilities, divided by the number of shares of common stock outstanding.

After giving effect to the sale of the shares of our common stock in this offering and after deducting underwriting discounts and commissions and our estimated offering expenses, our pro forma as adjusted net tangible book value would have been approximately $ million, or approximately $ per share of common stock. This represents an immediate increase in pro forma as adjusted net tangible book value of approximately $ per share to existing stockholders and an immediate dilution of approximately $ per share to new investors. The following table illustrates this calculation on a per share basis:

Assumed initial public offering price per share				$
Pro forma net tangible book value per share of common stock as of December 31, 2006
Pro forma as adjusted increase per share attributable to the offering

Pro forma as adjusted net tangible book value per share of common stock after this offering

Pro forma as adjusted dilution per share to new investors				$

If the underwriters exercise their overallotment option in full, the pro forma as adjusted net tangible book value as of December 31, 2006 will increase to approximately $ per share, representing an increase to existing stockholders of approximately $ per share, and there will be an immediate dilution of approximately $ per share to new investors.

The following table summarizes, as of December 31, 2006 on a pro forma as adjusted basis, the total number of shares of our common stock purchased from us and the total consideration and average price per share paid by existing stockholders and by new investors:

		Total shares		Total consideration
		Total shares		Total consideration		Average price per share
		Number	%	Amount	%	Average price per share
Existing stockholders			%	$	%	$
New investors			%		%
	Total		%	$	%	$

If the underwriters exercise their overallotment option in full, the following will occur:

•: the percentage of shares of our common stock held by existing stockholders will decrease to approximately % of the total number of shares of our common stock outstanding after this offering; and
•: the number of shares of our common stock held by new public investors will increase to , or approximately of the total number of shares of our common stock outstanding after this offering.

The tables and calculations above are based on shares outstanding as of December 31, 2006 on a pro forma basis and exclude shares of our common stock available for future grant under our 2007 Stock Incentive Plan.

SELECTED FINANCIAL DATA

Prior to this offering, we conducted our business through Monosol Rx LLC. Immediately prior to this offering, Monosol Rx LLC will merge with and into MonoSol Rx, Inc., a newly formed Delaware corporation, the shares of which are being sold in this offering.

The following table sets forth certain historical financial data for Monosol Rx LLC as of the dates and for the periods indicated. We have derived the selected historical statement of operations data for the years ended December 31, 2006, 2005 and 2004, and the balance sheet data as of December 31, 2006 and 2005, from the audited financial statements of Monosol Rx LLC included elsewhere in this prospectus. Prior to the formation of Monosol Rx LLC, our activities were carried out as part of the research and development efforts of Monosol, LLC, a manufacturer of commercial soluble films (the Predecessor). We have derived the historical financial data as of December 31, 2004 and 2003 (Predecessor), and for the year ended December 31, 2003 (Predecessor), from audited financial statements of Monosol Rx LLC that are not included in this prospectus. Since neither us nor our Predecessor were operating prior to 2003, no financial data has been presented for fiscal years prior to December 31, 2003. The historical results set forth below do not necessarily indicate results expected for any future period. The selected consolidated historical financial data should be read in conjunction with the discussion under the heading "Managements's Discussion and Analysis of Financial Condition and Results of Operations," and the historical financial statements and related notes included elsewhere in this prospectus.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of financial condition and results of operations in conjunction with the "Selected Financial Information" and the financial statements and the related notes included elsewhere in this prospectus. In addition to historical information, the following discussion and analysis includes forward-looking information that involves risks, uncertainties and assumptions. Our actual results and the timing of events could differ materially from those anticipated by these forward-looking statements as a result of many factors, including those discussed under "Risk Factors" and elsewhere in this prospectus. See "Special Note Regarding Forward-Looking Statements" included elsewhere in this prospectus.

Overview

We are a drug delivery company specializing in proprietary dissolving thin film pharmaceutical products. Since our inception in 2004, we have developed a significant portfolio of intellectual property and know how in thin film drug delivery, including formulation manufacturing, encapsulation and packaging. We are working with partners to develop thin film versions of their products for use in the prescription pharmaceutical, over-the-counter, or OTC, and consumer markets. Additionally, we began our self-funded initiatives by selecting prescription pharmaceutical products for development in our thin film technology based upon factors such as technical suitability, market opportunity, approved indications, patent expiration and other factors. We intend to further develop these products on our own before seeking a partner with the goal of maximizing our potential revenue.

Both with partners and through our self-funded initiatives we are currently developing a number of prescription products. This is a multi-phase process which includes regulatory filings for approval of our formulations prior to them being sold in the marketplace. We are vertically integrated in all critical phases of development and manufacture of our thin film.

We have incurred significant net losses since our inception in January 2004. As of December 31, 2006, we had accumulated net losses of $24.6 million, and our annual net loss has grown in size each year. Our losses have resulted principally from general and administrative expenses associated with developing our business and costs incurred in the research and development of our technologies. We expect to continue to incur net losses for the next several years as we pursue the development and commercialization of our product candidates.

We have financed our early stage operations with revenue from co-development arrangements and manufacturing and supply arrangements, the proceeds of capital contributions from our members and various debt offerings to affiliates of our members. In addition to proceeds from this offering, we may require additional financing to execute our business strategy.

Since the beginning of January 2006, we have added 49 employees, doubling the total size of our workforce, including contract employees and temporary employees. The growth in the size of our workforce included the hiring of our Chief Executive Officer and our Chief Financial Officer, as well as our Senior Vice Presidents of Business Development and Operations. We also added and plan to continue to add analytical scientists, packaging engineers and other manufacturing specialists necessary to attract and fulfill key customer contracts. These additional employees have increased dramatically, and will continue to increase our expenses in the short term but will enable the continued improvement of our thin film technology and development of products that we expect will produce revenue in the future.

In October 2006, we leased the Ameriplex facility which will become our primary development and analytical laboratories and manufacturing facility when retrofitting is complete in 2008. This facility will give us a state of the art cGMP manufacturing facility with enough capacity to hold all of our

operations and room to grow in the future. We expect to invest nearly $14 million in improvements to the facility over the next two years. This amount excludes investments in any additional equipment necessary to ensure we have the appropriate capabilities and capacity to support ongoing customers' needs.

In November 2006, we completed a private placement of equity and issued preferred membership interests in exchange for $16.9 million in cash and the settlement of $20.5 million principal amount of Tranche A and B notes, together with related accrued interest. This transaction allowed us to retire all of our outstanding debt and provided cash proceeds for product development and general corporate purposes, including capital expenditures and working capital.

Since January 2007, we have entered into a number of new customer agreements for the development and supply of various products in the prescription pharmaceutical, OTC pharmaceutical and non-pharmaceutical categories. Each of these contracts and the products they represent have different development timelines and, in some cases, regulatory requirements that will determine when the products will be commercially available and begin to produce revenue. In each case, we expect the development effort to generate milestone-based development revenue for us in the near term and ultimately supply and, potentially, royalty revenue in the long term.

Financial Operations Overview

Revenues and Cost of Goods Sold

We derive our revenues from two sources: manufacture and supply agreements and co-development and research fees. We currently generate manufacture and supply revenue from the production of thin film under commercial supply agreements with our customers for OTC products and a specialty application film. Co-development and research fees result from arrangements with third parties to test the applicability of and to develop products in thin film. These arrangements are usually for a finite period of time and are directed at a certain defined result. The fees may be related to completion of defined milestones. These arrangements may or may not lead to future research and development arrangements or manufacture and supply agreements.

Cost of goods sold is comprised of expenses related to manufacturing our thin film products, including raw materials, direct labor and fixed overhead. Our material costs include the costs of raw materials used in the production of our thin film drug delivery products and related packaging supplies. Direct labor costs consist of payroll costs (including benefits) of employees engaged in production activities. Fixed overhead principally consists of indirect payroll, facilities rent and depreciation for production machinery and equipment.

Our revenues and cost of goods sold are impacted by the following factors:

•

negotiated sales price with our partners for the products being manufactured;

•

our customers' supply requirements; and

•

costs of production, which includes:

•: raw materials, which we purchase at market prices; and
•: production efficiency (measured by the cost of a salable unit) which can increase or decrease based on the amount of direct labor and materials required to produce a product and the allocation of fixed overhead, which is dependent on the levels of production.

In the future, we expect to generate revenues from milestone payments for research and development activities and manufacture and supply agreements, which may include royalty payments.

Research and Development Expenses

Our research and development expenses reflect costs incurred in developing our thin film drug delivery technology, the development of our self-funded initiatives and external arrangements with third party partners. We expense research and development costs as incurred. Our partnered products generate co-development and research fees. Our research and development expenses consist primarily of:

•: salaries and related expenses for personnel;
•: costs of laboratory supplies and materials;
•: fees to professional service providers;
•: depreciation of capital assets used in the research and development process; and
•: allocated operating costs, such as the cost of facilities.

Our business is largely to identify presently marketed prescription pharmaceutical products that are suitable for thin film development. Our research and development cycle is shorter and less costly than the development of the pharmaceutical product itself. For each prescription thin film product we develop, we estimate that the research and development cycle will range between 24 to 30 months and total costs will be less than $5 million. The time frame and cost can be affected by the regulatory path we select or are required to follow and the extent to which regulatory authorities require follow-on clinical studies.

Research and development costs incurred by us during the last three fiscal years for internal proprietary projects and arrangements with third parties are as follows:

Fiscal Year	Internal Proprietary Projects		Arrangements With Third Parties		Total
2006	$	1,194,000	$	799,000	$	1,993,000
2005		899,000		359,000		1,258,000
2004		941,000		69,000		1,010,000

We expect to incur increasing research and development expenses in future periods as we expand our internal research capabilities and increase the number of self-funded initiatives, or SFIs, we expect to enroll in pre-clinical studies and clinical trials. The process of conducting pre-clinical studies and clinical trials necessary to obtain FDA approval is costly and time consuming. We consider the development of our product candidates to be crucial to our long-term success. If we do not complete development of our product candidates and obtain regulatory approval to market one or more of these product candidates, we may not be successful. The probability of success for each product candidate may be impacted by numerous factors, including the timing and results of our pre-clinical research programs, the scope, rate of progress and cost of our clinical trials, future clinical trial results, the cost and timing of regulatory approvals, and the effects of competing technologies and market developments. We will make ongoing evaluations of our product candidates and determine which product candidates to advance and how much funding to direct to each based on an ongoing basis in response to their scientific and clinical success and market potential.

General and Administrative Expenses

Our general and administrative expenses consist of salaries and benefits for executive and support personnel, professional fees for legal, accounting and other services, travel costs, facility-related costs such as rent, utilities for non-production activities and other general office expenses. These expenses include the following functions: corporate management, business development and licensing, finance, human resources, information systems and other administrative functions and unabsorbed

manufacturing overhead costs. We expect our general and administrative expenses to increase as we continue to hire new employees, expand our infrastructure and incur additional costs related to the growth of our business and our operations as a public company.

Results of Operations

Years Ended December 31, 2006, 2005 and 2004

Revenue. Manufacture and supply revenue increased $0.3 million, or 20% to $1.8 million in 2006 from $1.5 million in 2005. This increase is attributable to additional supply agreements we entered into with new customers and the initial demand generated by those contracts. Co-development and research fees increased $285,000, or 43% to $950,000 in 2006 from $665,000 in 2005. The increase was attributable to additional development arrangements with new customers. Manufacture and supply revenue decreased $0.4 million, or 21% to $1.5 million in 2005 from $1.9 million in 2004. This decrease is attributable to the discontinuation of business of one of our customers and the resulting termination of our relationship with that customer. Co-development and research fees increased $565,000, or 565% to $665,000 in 2005 from $100,000 in 2004. The increase was attributable to us commencing operations in 2004 and the expansion of our customer base in 2005.

Customer Concentration. Customers are considered major customers when sales exceed 10% of total net sales for the year or outstanding receivable balances exceed 10% of total receivables. For 2006, we had four major customers with sales totaling $2.5 million, or 93% of net sales, and outstanding receivables of $563,000, or 97% of total receivables. We had no major customers in 2005. For 2004, we had one major customer, with sales totaling $1.8 million, or 90% of net sales, and outstanding receivables of $1.0 million, or 91% of total receivables.

Cost of Goods Sold. Cost of goods sold increased by $0.3 million, or 23% to $1.6 million in 2006 from $1.3 million in 2005. This increase is attributable to the growth of revenue resulting from additional products sold as well as higher allocated overhead costs due to our adoption of Statement of Financial Accounting Standards, or SFAS, No. 151, Inventory Costs — an Amendment of Accounting Research Bulletin, or ARB, No. 43 effective January 1, 2006. These increases were partially offset by lower levels of excess and obsolete inventory in 2006. Cost of goods sold decreased by $0.1 million, or 7% to $1.3 million in 2005 from $1.4 million in 2004. This decrease was attributable to a decrease in manufacture and supply revenue resulting from the terminated relationship with a significant customer as described above, offset by increased costs for excess and obsolete inventory in 2005.

Research and Development Expenses. Research and development expenses increased by $0.7 million, or 54% to $2.0 million in 2006 from $1.3 million in 2005. Research and development expenses increased by $0.3 million, or 30% to $1.3 million in 2005 from $1.0 million in 2004. The increased expenses in 2006 and 2005 were attributable to increased staffing and infrastructure to support our internal research efforts along with costs associated with the increase in partnered research and development arrangements for which we generate co-development and research fees.

General and Administrative Expenses. General and administrative expenses increased by $3.9 million, or 53% to $11.3 million in 2006 from $7.4 million in 2005. General and administrative expenses increased by $4.2 million, or 131% in 2005 from $3.2 million in 2004. The increase of general and administrative expenses in 2006 and 2005 was attributable to the increase in the number of employees at our company from 11 full-time employees (inclusive of consultants and temporary workers) in 2004 to 36 and 63 full-time employees (inclusive of consultants and temporary workers) at the end of 2005 and 2006, respectively. In addition to increased staffing, we have incurred increased costs related to building our infrastructure and developing our business, including costs related to the recruitment of the current management team and other professionals, costs for additional facilities and

related depreciation, as well as costs for outsourced formulation, and analytical and design work to support our development efforts.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception in January 2004, we have never been profitable and as of December 31, 2006 we had accumulated net losses of approximately $24.6 million. Through December 31, 2006, we received net proceeds from debt and equity issuances of approximately $42.6 million as follows:

•: at our formation in January 2004, we received a $4.8 million contribution of net assets, including $0.4 million in cash;
•: later in 2004, we received an additional capital contribution of $6.6 million, including $4.8 million in cash;
•: during 2005 and 2006, we issued $20.5 million principal amount of Tranche A and B notes payable, along with stock purchase warrants. The notes had a ten year term and payment in kind interest at 4.33% and 4%, respectively; and
•: in November 2006, we closed a private placement for $38.4 million of preferred membership interests. A portion of the preferred interests were issued in settlement of amounts due under the Tranche A and B notes along with accrued interest. The net cash proceeds of $16.9 million are available for general corporate purposes including product development, capital expenditures and working capital. The preferred membership interests will be converted into shares of our common stock pursuant to the merger to occur prior to the offering.

We had $15.3 million in cash and cash equivalents as of December 31, 2006. Currently, our cash equivalents have a maturity of three months or less. The core of our strategy involves the development of our thin film drug delivery technology to targeted prescription pharmaceuticals. This area of product development is a multi-year process that requires significant expenditures prior to realizing any product revenue. We may need to raise additional funds through public or private debt or equity financings in order to develop or acquire new products or new product candidates, expand our manufacturing capacity, obtain FDA approval for our product candidates and continue our commercial growth. The proceeds from this offering will enable us to continue to execute our strategy, attract partners for co-development arrangements and ultimately develop products for commercial supply.

Cash Flow

Net Cash Used in Operating Activities. Cash used in operating activities was $9.3 million for the year ended December 31, 2006 and was primarily attributed to our $12.8 million net loss, offset by $3.5 million in non-cash charges such as depreciation, amortization and non-cash interest expense, and changes in operating assets and liabilities. Cash used by operating activities was $6.4 million for the year ended December 31, 2005 and was primarily attributed to our $8.3 million net loss, offset by $1.6 million in non-cash charges such as depreciation, amortization, non-cash interest expense and the write-off of accounts receivable, and changes in operating assets and liabilities. Cash used by operating activities was $3.4 million for the year ended December 31, 2004 and was primarily attributed to our $3.6 million net loss, offset by $0.5 million in non-cash charges such as depreciation and amortization and changes in operating assets and liabilities.

Net Cash Used in Investing Activities. Cash used in investing activities was $3.4 million, $2.8 million and $1.2 million for the years ended December 31, 2006, 2005 and 2004, respectively, and was attributable to capital expenditures for property, plant and equipment.

Net Cash Provided by Financing Activities. Cash provided by financing activities was $26.5 million for the year ended December 31, 2006 and was primarily attributable to the $16.9 million in net proceeds from the issuance of Series A Preferred Interests and $10.0 million in net proceeds from the issuance of notes payable with warrants. Cash provided by financing activities was $10.2 million for the year ended December 31, 2005 and was primarily attributable to $10.5 million in net proceeds from the issuance of notes payable with warrants. Cash provided by financing activities was $4.9 million for the year ended December 31, 2004 and was primarily attributable to $5.1 million in capital contributions from members.

Funding Requirements

Upon completion of this offering, we believe that the net proceeds from this offering, together with our existing cash and cash equivalents, as supplemented by our revenue, will be sufficient to meet our projected operating requirements for approximately the next 24 months. We have based this estimate on assumptions that could change, and we could utilize our available financial resources sooner than we currently expect. The key assumptions underlying this estimate include:

•: the costs necessary to successfully complete our development efforts for thin film versions of existing drugs and other self-funded initiatives;
•: the levels and timing of revenues from the commercialization of our product candidates;
•: the capital expenditures required to support our increasing development and manufacturing capacity needs; and
•: the infrastructure costs to support a public company.

We may require substantial additional capital due to the uncertainty and risks related to the time it will take for our product candidates to complete the clinical trial process, obtain approval from regulatory authorities and to be successfully commercialized. We may raise additional capital through public or private equity offerings, debt financings, corporate collaborations or other means. We may attempt to raise additional capital due to favorable market conditions or other strategic considerations even if we have sufficient funds for planned operations. To the extent that we raise additional funds by issuance of equity securities, our stockholders may experience dilution, and debt financings, if available, may involve restrictive covenants or may otherwise constrain our financial flexibility. To the extent that we raise additional funds through collaborative arrangements, it may be necessary to relinquish some rights to our intellectual property or grant licenses on terms that are not favorable to us. In addition, payments made by potential collaborators or licensors generally will depend upon our achievement of negotiated development and regulatory milestones. Failure to achieve these milestones may harm our future capital position. If at any time sufficient capital is not available, either through existing capital resources or through raising additional funds, we may be required to delay, reduce the scope of, eliminate or divest one or more of our research, pre-clinical or clinical programs.

Seasonality

To the extent we are producing OTC cough, cold and allergy pharmaceutical products, which by nature are seasonal, we could experience some seasonality in revenues in the second and third quarters of 2007 and 2008. In the long term, our strategy is to target selected prescription pharmaceuticals on thin film that are not cough, cold and allergy pharmaceutical products. As those products are brought to the market and they begin to represent a larger share of our product portfolio, the effects of seasonality caused by any cough, cold and allergy products will be diminished.

Contractual Obligations

Our contractual obligations relate to operating leases for our facilities and purchases of production equipment.

The following table sets forth a summary of our contractual obligations as of December 31, 2006:

Contractual Obligations		Total		Less Than One Year		One to Three Years		Four to Five Years		After Five Years
Operating lease obligations		$	2,879,098	$	588,102	$	1,074,988	$	1,088,412	$	127,596
Equipment purchase obligations			3,690,000		3,690,000		—		—		—

	Total	$	6,569,098	$	4,278,102	$	1,074,988	$	1,088,412	$	127,596

Operating Lease Obligations. We have various lease agreements for our production and research facilities and offices. Most leases contain renewal options, some contain purchase options and some require us to pay for taxes, maintenance and operating expenses. In October 2006, we entered into a lease for the Ameriplex facility. The lease expires in March 2012 with options to extend through March 2021, and a right of first refusal to purchase the facility. In July 2006, we entered into a lease for our headquarters located in Warren, New Jersey. The lease expires in 2011. We lease our current production facility in Portage, Indiana which houses our research and development, offices and manufacturing operations. This lease expires in March 2008, with an option to extend through March 2010. This lease also contains a purchase option at a fixed price. We also lease a small technology development laboratory in Kingsport, Tennessee. The lease related to the Kingsport, Tennessee laboratory expires in December 2009.

Equipment Purchase Obligations. In 2007, we intend to purchase a new film casting line to fulfill production requirements under a commercial supply agreement. The equipment will be purchased with cash and the customer that is a party to the supply agreement is obligated to make capacity commitment payments over two years that equal the cost of the equipment and any other capital expenditures related to its installation.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements.

Taxation

Our predecessor, Monosol Rx LLC, operated as a limited liability company which, for federal, state and local income tax purposes was treated as a partnership. As such, in lieu of company-level income taxes, its members were subject to tax on their respective pro rata shares of Monosol Rx LLC's income, deductions, gains, losses and credits, as allocated in accordance with the members' operating agreement. Because Monosol Rx LLC was treated as a partnership for federal, state and local income tax purposes, no income taxes have been recognized in the accompanying financial statements, except for certain state non-income taxes, which are immaterial and included in general and administrative expenses. Effective on the merger of Monosol Rx LLC into MonoSol Rx, Inc., we will be subject to corporate-level income tax under subchapter C of the Internal Revenue Code for federal income tax purposes, as well as under state and local income tax laws. In accordance with U.S. generally accepted accounting principles, or GAAP, we are required to estimate the future tax consequences attributed to temporary differences between the financial statement and income tax bases of our assets and liabilities and record a deferred tax asset or liability. In the unaudited pro forma financial statements contained elsewhere in this prospectus, we recorded a $900,000 one-time non-cash charge on the statement of operations to recognize the deferred tax liability related to existing taxable temporary differences that

will reverse in future periods. The temporary differences resulted principally from depreciation of property and equipment, and amortization of intangibles.

Performance Unit Plans

Our predecessor, Monosol Rx LLC, has maintained two Performance Unit Plans for the purpose of enhancing our long-term growth by providing incentives to key employees and other service providers. The performance units were granted with a base value equal to their estimated fair value at the date of grant, both of which were determined by our board of directors. The Performance Unit Plans call for accelerated vesting upon a change in control or an initial public offering. The vested units can be redeemed for cash or in the form of the same equity instruments received due to a change in control or an initial public offering, at the discretion of the board of directors. The payment to a participant is based on the spread between the fair value of the performance units at the time of the change in control or initial public offering and the base value of the performance units the participant was awarded. After the merger of Monosol Rx LLC with MonoSol Rx, Inc. and immediately prior to this offering, the performance units will be exchanged for common stock of MonoSol Rx, Inc. and we will incur compensation expense in the estimated amount of $ million, which has been reflected in the unaudited pro forma financial statements included elsewhere in this prospectus.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based on the financial statements, which have been prepared in accordance with GAAP. The preparation of the financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are more fully described in Note 1 to the financial statements appearing elsewhere in this prospectus. We believe that the following accounting policies relating to revenue recognition, research and development expenses, inventory valuation, intangibles and impairment of long-lived assets are most critical to aid you in fully understanding and evaluating our reported financial results.

Revenue Recognition

Our research and development agreements contain development milestones that we must meet in order to earn fees. In addition, these agreements often require that we achieve certain results in order to have the opportunity to earn additional fees and revenues. Product sales are generally a result of previous research and development efforts.

We recognize revenue in accordance with Staff Accounting Bulletin, or SAB, No. 101 Revenue Recognition in Financial Statements, as amended by SAB No. 104. For manufacture and supply arrangements, we recognize revenue when products are shipped and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, pervasive evidence of an arrangement exists and the sales price is fixed or determinable. In instances where we utilize a third-party to complete the packaging process, revenue is recognized when the completed product is shipped from the third-party. In the case of co-development and research fees, revenue is recognized when appropriate contractual milestones are realized, contractual amounts for those services are billed and collection of related receivables is probable.

Inventory Valuation

Due to our continual change in customer mix, we evaluate the utility of our inventory frequently. Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. Our inventories are evaluated for recoverability on a periodic basis and any non-usable inventory is written-off to expense. In addition, we establish a reserve for any inventory that may be stated in excess of its recoverable amount or potentially non-usable. Charges for such write-off and reserves are recorded as a component of cost of goods sold.

Impairment of Long-Lived Assets

Our property, plant and equipment are exposed to technological obsolescence. Management reviews the utility of these long-lived assets annually. In accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long Lived Assets, long-lived assets such as property, plant and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. Impairment, if any, is measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value. In 2006, as a result of management's evaluation of our property, plant and equipment, we recorded an impairment charge of $132,000.

Intangible Asset

Management evaluates the utility of our intellectual property underlying our principal production capabilities annually. Our intangible asset relates to composition and process technology used in thin film technology acquired as part of the Kosmos Pharma Limited acquisition in 2004 (see Note 2 in accompanying financial statements). We amortize these intangible assets on a straight-line basis over 10 years which is the expected useful life of the associated technology.

Research and Development Costs

We expense costs associated with research and development activities as incurred. Research and development costs include costs incurred for our internal proprietary research and development projects as well as costs incurred under arrangements with third parties for which we generate co-development and research fees.

Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risk due to changes in interest rates relates primarily to the increase or decrease in the amount of interest income we can earn on our investment portfolio. We attempt to increase the safety and preservation of our invested funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in short-term investment grade debt instruments. Due to the short-term nature of our investments, we do not believe that we have any material exposure to interest rate risk arising from our investments. We do not purchase, sell or hold derivatives or other market risk sensitive instruments to hedge interest rate risk or for trading purposes. All of our investment choices are consistent with and driven by good cash management practices.

Changes In and Disagreements with Accountants on Accounting and Financial Disclosure

In April 2006, our manager's general partner approved the engagement of KPMG LLP, or KPMG, to audit our financial statements for the fiscal years ended December 31, 2006, 2005, 2004 and 2003. Prior to our retention of KPMG, McGladrey & Pullen, LLP, or McGladrey, served as our certified

independent accountants and reported on our financial statements for the fiscal year ended December 31, 2004. McGladrey was dismissed as our principal accountant on April 3, 2006.

McGladrey's report on our financial statements did not contain an adverse opinion or a disclaimer of opinion and the financial statements were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2005 and 2004, and during the subsequent interim period between December 31, 2005 and McGladrey's dismissal, there were no disagreements with McGladrey on any matter of accounting principle or practice, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of McGladrey, would have caused it to make reference to the subject matter of the disagreement in connection with its report on our financial statements. In addition, during the fiscal years ended December 31, 2005 and 2004, and during the subsequent interim period between December 31, 2005 and McGladrey's dismissal, there were no reportable events pursuant to Item 304(a)(1)(v) of Regulation S-K.

During the fiscal years ended December 31, 2005 and 2004, and during the subsequent interim period between December 31, 2005 and McGladrey's dismissal, we did not consult with KPMG regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our financial statements, or (ii) any matter that was either the subject of a disagreement or a reportable event with McGladrey.

Recent Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a threshold of more-likely-than-not for recognition of tax benefits of uncertain tax positions taken or expected to be taken in a tax return. FIN 48 also provides related guidance on measurement, derecognition, classification, interest and penalties, and disclosure. The provisions of FIN 48 was effective for us on January 1, 2007, with any cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. We are in the process of assessing the impact of adopting FIN 48 on our results of operations and financial condition.

BUSINESS

Overview

We are a drug delivery company specializing in proprietary dissolving thin film pharmaceutical products. Our thin film, which is similar in size, shape and thickness to a postage stamp, dissolves rapidly and utilizes a novel process and proprietary encapsulation compositions to mask the taste of the drug contained within the film. We believe these qualities render our thin film easy to use and consequently will improve patient compliance, providing a significant benefit to patients, their prescribing physicians and healthcare institutions. Our thin film drug delivery technology is currently used in the over-the-counter, or OTC, marketplace and we are developing thin film containing prescription drugs. By incorporating approved drugs with soon-to-expire or expired patents into our thin film, we believe we can extend their patent lives and protect the billions of dollars of drug revenues important to our existing and future pharmaceutical partners. Furthermore, we are building the infrastructure required to produce our thin film rapidly and at scale.

We believe we are the only company completely dedicated to thin film as a drug delivery dosage form and have created a vertically integrated infrastructure to ensure leadership capabilities in the critical activities of drug tastemasking, analytical development, global formulation development, manufacturing and packaging. We have invested significantly in this model of vertical integration to develop an operational infrastructure that we believe will position us to seamlessly commercialize products in concert with our partners' respective sales forces.

We have pursued and plan to continue to pursue four different strategic revenue paths to profitability. We plan to develop thin film versions of existing prescription products under partner-funded agreements. We also expect to self-fund the development of versions of existing prescription products which we intend to ultimately partner. We also plan to partner with pharmaceutical companies to develop and deliver new prescription products with improved efficacy and to continue to commercialize products in the OTC marketplace.

Our Business Strategy

Our strategy is to develop and partner innovative thin film strip products in the prescription, generic and OTC pharmaceutical markets and to establish a leadership position in thin film drug delivery technology through continued development of our drug delivery technology and our intellectual property portfolio. We believe that pharmaceutical companies will want to partner with us to extend the life cycle of their products, defend against patent expiration, protect against generic encroachment and

differentiate their products in competitive categories. To achieve these goals, our strategy includes the following key elements:

•: Self-fund the development of thin film versions of existing prescription products. We are currently developing a portfolio of thin film formulations of existing prescription drugs. We select our targets based upon technical suitability for our thin film drug delivery technology, patent expiration, approved indications, market size and other factors. We intend to maximize the commercial value of these drugs by seeking to partner with the drug innovators to enable them to extend the life cycle of their prescription drugs. We believe this strategy will result in superior economics for us as compared to initiatives where partners initially fund the product development program as we have taken on most of the development risk.
•: Develop thin film versions of existing prescription products with pharmaceutical partners. In contrast to our self-funded initiatives, we are also currently developing a number of thin film formulations of existing prescription products under partner-funded agreements. Together with our development and marketing partners, we have selected targets based upon technical suitability for our thin film drug delivery technology, patent expiration, patient demographics approved indications and other factors. Similar to our self-funded initiatives, we believe these agreements will enable our partners to manage the life cycle of their prescription drugs. When compared to our self-funded initiatives, the development costs and risks associated with partnered products are significantly reduced.
•: Partner with pharmaceutical companies to deliver new prescription products with improved efficacy. For certain drugs, we believe our thin film drug delivery technology, when utilized for sublingual (under the tongue), buccal (in the cheek) or vaginal delivery may improve efficacy. Improved efficacy can occur through faster onset of action or lower dosing which may also result in reduced side effects and improved safety. We believe that the potential to deliver prescription drugs with improved efficacy will make us a desirable partner for pharmaceutical companies.
•: Position ourselves to be a partner of choice for thin film drug delivery technology through vertical integration. We will continue to maintain and control critical capabilities in tastemasking and analytical development, global formulation, manufacturing and packaging of thin film. We are dedicated to a model of vertical integration and have invested significantly to develop an operational infrastructure that we believe will position us to seamlessly commercialize products in concert with our partners' respective sales forces. We believe our vertical integration benefits our partners by allowing us to: (i) research, develop, manufacture and package more quickly and cost effectively than if we were dependent on others; (ii) better develop and protect our intellectual property and institutional expertise; (iii) reduce the risk of third-party performance and quality; and (iv) better manage compliance related to pharmaceutical manufacturing standards.
•: Continue to develop our intellectual property portfolio to position ourselves as a market leader in thin film drug delivery technology. We believe our existing intellectual property portfolio in thin film drug delivery is a significant source of competitive advantage. We intend to continue to develop our thin film intellectual property portfolio in areas such as film composition, drug uniformity, tastemasking, methods of manufacture and packaging. We believe our intellectual property portfolio provides us with significant protection against competition.
•: Continue to commercialize products in the OTC marketplace. In the near term, we intend to continue to develop and commercialize OTC pharmaceutical products utilizing our proprietary thin film drug delivery technology. The process for regulatory approval of most OTC pharmaceutical products, the monograph system, should enable us to leverage our existing research and development capabilities and operational infrastructure to generate near-term revenue and cash flow. We believe that continued commercialization of OTC products utilizing

the thin film dosage form will further build consumer acceptance and industry awareness of our thin film drug delivery technology.

Industry Overview

Drug Delivery Methods

Drug delivery companies apply proprietary technologies to create pharmaceutical products that improve the administration, absorption, efficacy, differentiation or cost of marketed pharmaceutical products. Drug delivery and related technologies have facilitated the improved delivery of drugs through a variety of means including oral (through controlled release, quick dissolve and liquids), injection, transdermal (through the skin), transmucosal (through the mucous membranes of the nose and mouth), intranasal and pulmonary methods. According to Front Line Strategic Consulting, U.S. sales of advanced drug delivery systems was $64.1 billion in 2005 and is projected to increase to approximately $153.5 billion by 2011.

Drugs incorporating rapid-dissolve technology, like thin film, are particularly suitable for use by children, geriatric patients, and individuals with certain physiological conditions that create a difficulty in swallowing, or dysphagia. In addition, according to industry data, forty percent of people report problems swallowing tablets. Since rapid-dissolving dosage forms containing drugs are easier to swallow and often incorporate tastemasking technology, they have the potential to enhance patient compliance relative to conventional tablets. Furthermore, when compared to liquid formulations, rapid-dissolve technology may also improve dosing accuracy resulting in improved patient outcomes.

Thin film strips were first introduced in 2001 by Warner-Lambert Consumer Healthcare in the form of the Listerine PocketPak®. We believe the global success of the product demonstrates consumer acceptance of thin strips. Novartis Consumer Health was the first major pharmaceutical company to launch several thin strip OTC pharmaceutical drug products under its Triaminic® and TheraFlu® brands. As demonstrated in the chart below based on IRI Infoscan data, Triaminic® Thin Strips have significantly outsold Triaminic® Softchews, its rapid dissolve alternative, since its introduction into the market.

Triaminic® Thin Strips and Triaminic® Softchews Sales Trends

Other thin film products on the market today include Prestige Brands' subsidiary's, Medtech Products Inc., or Medtech, Chloraseptic® strips for sore throat, Pfizer's Sudafed PE® phenylephrine strips, and Novartis' Gas-X® simethicone strips.

Trends in the Pharmaceutical Industry

Growth in the drug delivery industry is being driven by several significant trends in the healthcare industry. We believe pharmaceutical companies are becoming increasingly focused on life cycle product management. Life cycle product management is an issue due to expiring patents, generic encroachment and declining new drug pipelines. In addition to life cycle management, other trends in the pharmaceutical industry include an increase in direct-to-consumer marketing and the continued influence of managed care on reducing costs of treatment. The following is a more detailed discussion of these trends:

•: Drug patent expiration and increased generic competition. We believe that pharmaceutical companies will adopt innovative drug delivery systems as a means of enhancing patient benefits and differentiating themselves from competition while preserving or increasing market share over the life cycle of a product. There are 83 major drugs, each with 2006 U.S. sales of $100 million or greater, that are expected to lose patent or exclusivity protection through 2012. Collectively, these drugs represent 2006 U.S. sales of approximately $95 billion, or 40% of the total U.S. retail pharmaceutical market. As a result, many pharmaceutical companies are increasingly focused on product life cycle management to protect the revenue from these products. One way that pharmaceutical companies are enhancing existing drug products is with innovative drug delivery technologies. These enhancements may include increased efficacy, improved compliance, reduced side effects and more convenient administration, any of which may provide a significant advantage over existing and future competition. We believe that pharmaceutical companies will continue to use drug delivery systems to preserve or increase market share, enhance efficacy, and extend product revenue life cycles. Generic competition occurs when a generic company markets a product that a pharmacist may substitute for the branded product in the event that the physician's prescription allows for substitution. In all states, except California, a pharmacist can substitute a generic product for a branded product solely where the Food and Drug Administration, or FDA, has confirmed therapeutic equivalence, also known as an "AB" rating, for the generic product. To obtain an "AB" rating, a generic company must demonstrate that its generic product contains the same drug, results in comparable drug blood levels to the branded product and is in the same dosage form. We believe our thin film will not be "AB" rated with either conventional tablets or capsules, or with orally dissolving tablets, or ODTs, since thin film is considered to be a different dosage form by the FDA.
•: Declining new drug pipelines. In recent years, the development of new drugs has slowed dramatically while the cost of developing new drugs has increased. From 1996 to 2003, the number of new drug molecules approved annually by the FDA declined 60% and the number of new drug applications dropped by 45%. Also, according to industry data, by 2004 new drug research and development spending approached $40 billion a year, but the number of new drugs approved per year had fallen. This slowdown in new drug approval is occurring at the same time that the pharmaceutical industry is facing patent expirations on major revenue producing drugs. As a result, we believe that pharmaceutical companies are motivated to find new ways of marketing existing drugs, in part through the use of advanced drug delivery technology such as thin film.
•: Increased direct-to-consumer marketing is raising consumer awareness and demand for alternative dosage forms. In recent years, pharmaceutical companies have brought tremendous resources to bear on direct-to-consumer advertising and education efforts. According to a November 2006 U.S. Government Accountability Office study, the amount that drug companies

spent on direct-to-consumer advertising between 1997 and 2005 increased twice as fast as spending on promotion to physicians or on research and development. IMS Health estimated that, from 1997 through 2005, spending on direct-to-consumer advertising in the United States increased from $1.1 billion to $4.2 billion, an average annual increase of almost 20%. We believe this increased spending on direct-to-consumer marketing has raised consumer awareness of and demand for products that incorporate unique and innovative drug delivery technologies, such as film strip technology.

•: Influence of managed care. The Centers for Medicare & Medicaid Services estimates that healthcare spending through 2016 will grow at an average annual growth rate of 6.9%, with total health spending in that period of about $33.4 trillion. To address this issue, managed care providers and other insurers are keenly interested in products and technologies that help increase patient compliance thereby lowering the overall cost of treatment. Since the elderly, infant and juvenile patient populations typically have more frequent dosing requirements and a higher incidence of difficulty swallowing traditional oral solid dosage forms, we believe that physicians, patients, as well as managed care providers and other insurers, will seek out products incorporating advanced drug delivery systems to address the needs of these populations where compliance and accurate dosing are essential to proper treatment.

Our Solution

We have developed a thin film drug delivery technology that we believe will be embraced by patients, prescribing physicians, healthcare providers, and pharmaceutical drug marketers. Our thin film, which is similar in size, shape and thickness to a postage stamp, dissolves quickly in the mouth and effectively hides the taste of the drug it contains. We believe these qualities render our thin film easy to use and consequently will improve patient compliance, providing a significant benefit to patients, their prescribing physicians and healthcare institutions. By incorporating approved drugs with soon to expire or expired patents into our thin film, we believe we can extend their patent lives and help protect the billions of dollars of drug revenues important to our existing and future pharmaceutical partners. Furthermore, we are building the infrastructure required to produce our thin film rapidly and at scale. We believe this combination creates a compelling partnering proposition for pharmaceutical companies who are in need of significant differentiation from branded competitors and generic drug manufacturers.

We believe that our thin film drug delivery technology will have strong physician, patient and consumer acceptance. Evidence of this acceptance can be seen in the OTC pharmaceutical market where thin film pharmaceutical products have increased brand share and provided consumers with a preferred alternative to conventional tablets, orally dissolving tablets and other dosage forms. We believe our thin film drug delivery technology possesses several key advantages over existing drug delivery forms such as convenience, ease of dosing, portability and absence of the need for water or liquids; improved dosing accuracy relative to liquid formulations; accurate administration of drugs for the pediatric, geriatric and mentally ill patients where proper dosing can be difficult; and provides an easy alternative to patients with swallowing disorders and those who dislike taking other solid dosage forms such as tablets or capsules.

For many of the same reasons we think our thin film delivery technology will appeal to physicians, patients, and consumers, we also believe our thin film drug delivery technology will appeal to healthcare providers. Compared to quick-dissolve tablet technologies, our strips disintegrate faster, are more durable, have excellent stability and are cost effective. In addition, our thin film accommodates unit dose packaging and is highly portable and discreet. Because our thin film is easy to use, we believe our thin film technology may be a more effective means of drug delivery and may reduce the burden of repetitive daily dosing. Consequently, we believe our thin film will improve patient compliance with prescribed drug regimens reducing the need for repeat treatments.

We also believe our thin film drug delivery technology offers prescription pharmaceutical companies a compelling value proposition by enabling them to better manage the revenue life cycles of their products. Not only does our thin film drug delivery technology offer a unique ability to extend pharmaceutical product life through a non-"AB" rating but we also believe that our thin film drug delivery technology provides the essential characteristics necessary for product differentiation, performance and compliance with global drug standards. These characteristics include (i) limited clinical data requirements (505(b)(2) application, abbreviated new drug application, or ANDA, or European Union Mutual Recognition Procedure regulatory pathways), (ii) speed of dissolution, (iii) load capacity or ability to carry the drug, (iv) compatibility with tastemasking techniques, (v) manufacturing scalability, (vi) content uniformity, (vii) stability, (viii) an extensive and protective intellectual property portfolio and (ix) a highly differentiated patient friendly delivery form. Furthermore, we are dedicated to thin film as a drug delivery dosage form and have created a vertically integrated infrastructure to ensure leadership capabilities in drug tastemasking, analytical development, global formulation development, manufacturing and packaging.

Our Product Development

We plan to develop and market our innovative thin film strip products in the prescription drug and OTC markets by pursuing four distinct revenue-generating strategies: (i) self-funded initiatives, or SFIs; (ii) partnered existing prescription products; (iii) partnered new prescription products; and (iv) partnered OTC pharmaceuticals and other products. We have identified and undertaken a number of self-funded initiatives, or SFIs, to develop thin film versions of existing products, which we ultimately intend to bring to market with a partner. We have also been engaged by pharmaceutical partners to develop thin film versions of existing prescription products. In the future, we expect to partner with pharmaceutical companies to deliver new prescription products with improved efficacy. We also expect to continue to develop and commercialize thin film products in the OTC and consumer marketplace.

Self-Funded Initiatives

We are developing thin film versions of a series of major revenue producing prescription drugs. We believe that these products can be approved on the basis of limited clinical data and on a development to approval timeline of 24 to 30 months. We plan to advance development of these initiatives until we realize certain product-specific development milestones, at which point we expect to attract partners with whom we will commercialize these film products. We have a large pool of drugs to choose from for thin film development because we believe our technology can be applied to over 400 drugs due to its load capacity. As a result, there are many candidates suitable for development utilizing our thin film drug delivery technology and we intend to carefully evaluate those candidates to determine their suitability for internal development.

The following chart summarizes potential SFI candidates by therapeutic category, number of candidates within each category and market opportunity based on 2005 worldwide sales:

Potential Self-Funded Initiative Candidates

Category	Number of Candidates	2005 Global Category Market Value in U.S. $ (Billions)
Anti-Psychotics	5+	$	11.0+
Pain	15+		6.0+
Neurodegenerative Disease Treatments	12+		4.5+
Urinary Incontinence	7		3.0+
Anxiety/Depression	20+		15.0+
Erectile Dysfunction	3		2.5+

We believe that these products can be approved on the basis of limited clinical data through the 505(b)(2) or ANDA regulatory pathways. For additional information, see the section of this prospectus entitled "Government Regulation." As thin film versions, these prescription drugs can strategically enter the global marketplace to minimize generic encroachment and in some cases allow sufficient marketing time to effectively replace the current dosage form with our non-generically substitutable film. In doing so, the drug's innovator can preempt generic introductions and retain the brand's sales and market share beyond ordinary patent expiration.

We are currently self-funding the development of the following pharmaceutical products:

Self-Funded Initiatives

Brand Name	Drug	Patent Expiration	Category	U.S. Sales (Billion)*		Partner	Status
Ambien®	Zolpidem Tartrate	Expired	Sleep	$	2.3	To Be Determined	In Clinical Trials

*: sales reported for fiscal year 2006

Zolpidem Tartrate

Zolpidem is a short-term insomnia medication and has a favorable side effect profile. Zolpidem is marketed by Sanofi-Aventis under the brand name Ambien® and generated sales of $2.3 billion in 2006.

In April 2007, Ambien® lost patent protection and is presently subject to generic competition. Zolpidem's revenue, dose, patent expiration, compatibility with our dosage form and category competitive needs make it an ideal choice for development utilizing our thin film drug delivery technology. Our zolpidem thin film is currently in pilot bioequivalence trials.

Ondansetron HCI

Ondansetron is a selective 5-HT3 receptor antagonist approved and commonly used to prevent nausea and vomiting due to chemotherapy, radiation treatments and following surgical procedures. Ondansetron is marketed by GlaxoSmithKline plc, or GSK, under the brand name Zofran® and generated sales of $1.3 billion in 2006.

In December 2006, Zofran® lost patent protection and is presently subject to generic competition. Zofran's® revenue, dose, patent expiration, compatibility with our dosage form and category competitive needs make it an ideal choice for development utilizing our thin film drug delivery technology. Our dosage form makes it easier to administer ondansetron, especially for those patients who have difficulty swallowing after chemotherapy. Dosing with our thin film does not require water which may help to reduce further nausea due to the need for liquids in taking other dosage forms. Our ondansetron thin film is scheduled for pilot bioequivalence trials in the third quarter of 2007.

Donepezil HCI

Donepezil is an acetylcholinesterase inhibitor that is used as a treatment for Alzheimer's Disease. Donepezil is marketed by Eisai Inc. under the brand name Aricept® and generated sales of $1.1 billion in 2006.

In November 2010, Aricept® is expected to lose its patent protection and be subject to generic competition. Aricept's® revenue, dose, future patent expiration, compatibility with our dosage form and category competitive needs make it an ideal choice for development using our thin film drug delivery technology. Our dosage form makes it easier to administer donezepil, especially to those elderly patients who have difficulty swallowing traditional dosage forms, such as tablets. We believe our thin film provides an immediate ease of use benefit for both the patient and the caregiver. Complete and swift dosing associated with thin film drug delivery also may reduce caregiver anxiety. Our donezepil thin film is currently in pre-clinical development.

Escitalopram Oxalate

Escitalopram is in a class of drugs called selective serotonin reuptake inhibitors. It is approved for depression and generalized anxiety disorders. Escitalopram is marketed by Forest Laboratories, Inc. under the brand name Lexapro® and generated sales of $2.0 billion in 2006.

In March 2012, Lexapro® is expected to lose its patent protection and be subject to generic competition. Escitalopram's revenue, dose, future patent expiration, compatibility with our dosage form and category competitive needs make it an ideal choice for development utilizing our thin film drug delivery technology. Our escitalopram thin film is currently in pre-clinical development.

Our Partnered Products

We are currently engaged with pharmaceutical partners to develop thin film versions of existing prescription products. The following is a chart summarizing our disclosed partnered prescription products:

Disclosed Partnered Prescription Products

Product		Category		Partner		Status
Ketorolac		Menstrual Pain		UMD Inc.		Pre-Clinical Work Complete
Multiple Products		Respiratory		Adams Respiratory Therapeutics, Inc.		Pre-Clinical Work Complete

We have entered into pharmaceutical partner-funded agreements with companies to develop bioequivalent, thin film versions of existing drugs. We anticipate pursuing these products through either the 505(b)(2) or ANDA regulatory pathways. Under partnership agreements, our pharmaceutical partners fund the development program, regulatory submission and ultimately advertise, promote and market the new thin film product. One of the companies we have partnered with is Adams Respiratory Therapeutics, or Adams, for a thin film product for certain respiratory indications.

We also currently, and in the future, expect to partner with pharmaceutical companies to deliver new prescription products with improved efficacy. Such improved results may be achieved through, for example, sublingual delivery (under the tongue) for those drugs suitable for absorption in that manner. These agreements consist of development fees, milestone payments, manufacturing fees, and royalties as a percentage of sales. We believe these products have the potential to offer maximum value but also involve longer development timelines and more rigorous clinical requirements compared to our

bioequivalent thin film versions of existing pharmaceutical products. We anticipate pursuing approval of these products with our partners through the new drug application, or NDA 505(b)(1), or 505(b)(2) regulatory pathways. One of the improved products we are developing, in conjunction with UMD Inc., is a vaginal film to treat menstrual pain. To date, this thin film product has achieved successful proof of principle bioavailability studies.

Our OTC Pharmaceuticals and Other Products

We are currently developing and expect to market a number of OTC and other products with our partners. The following is a chart summarizing our partnered OTC and other products:

Partnered OTC Pharmaceuticals and Other Products

Product *Brand Name*	Category	Partner	Status
Dextromethorphan	Cough	Vita Health Products, Inc.	In Production
Diphenhydramine HCl	Cough	L. Perrigo Company	Prototypes Complete
Benzocaine Chloraseptic®	Sore Throat	Medtech Products Inc.	In Production

We have entered into an agreement with Prestige Brands' subsidiary, Medtech, to develop and supply thin film containing benzocaine for the Chloraseptic® brand. We have also entered into agreements with Perrigo (for a store brand, diphenhydramine product), and CNS, Inc. (now owned by GSK) to develop and commercialize an anti-snore strip for the Breathe Right® franchise. In addition, we have partnered with Philip Morris USA to supply a long lasting specialty application film. We also have a development program in place with Angelini Pharmaceuticals of Italy for an anti-inflammatory thin film product. The appropriate regulatory pathways will be followed to commercialize these products.

Competition

We compete with drug delivery companies utilizing advanced technologies involving oral, injectable, patch-based, pulmonary and intranasal administration of pharmaceutical products. We also may compete with pharmaceutical companies seeking to develop and produce their own thin film products. However, some pharmaceutical companies have opted to partner with third-party technology providers rather than develop and manufacture their own delivery technologies in-house. However, such a trend may not continue in the future.

While there are several competitors in the thin film drug delivery market, we believe there are two primary competitors, Adhesives Research and Lohmann Therapie Systems. We compete against these companies to attract and retain partner relationships for the development and manufacture of thin film pharmaceuticals.

We differentiate ourselves through our vertically integrated business model which we believe increases our speed to market, reduces third-party performance risk and increases control from a regulatory perspective. We believe our proprietary composition, tastemasking and manufacturing process provides us with a competitive advantage in thin film.

Our Inventors

We believe our proprietary thin film drug delivery technology is supported by our portfolio of intellectual property. Our senior management and consultants are named inventors on many of our pending patent applications. We believe that we have a strong team of inventors with particular experience in drug delivery and medical sciences. We believe that our portfolio of intellectual property is a source of competitive strength for us.

Our primary inventor to date is Richard C. Fuisz, M.D., one of our consultants. Dr. Fuisz founded Kosmos Pharma, the assets of which we substantially acquired in 2004. Dr. Fuisz is a named inventor for our issued Irish patent and on 65 of our pending worldwide patent applications.

Garry Myers, is our senior director of product development. Mr. Myers is a named inventor on 60 of our pending worldwide patent applications.

Dr. Pradeep Sanghvi, is our vice president for pharmaceutical development. Dr. Sanghvi is a named inventor on 7 of our pending worldwide patent applications.

A. Mark Schobel is our chief executive officer. Prior to joining us, he was a named inventor on 12 issued patents ranging from controlled release methods to diagnostic devices.

Joseph Fuisz, the son of Dr. Fuisz, is a named inventor on 41 of our pending worldwide patent applications.

Intellectual Property

Developing and protecting our global thin film intellectual property portfolio is a key component of our business strategy. Through our intellectual property we seek to attract partners for our products, deter new entrants from developing competing thin film drug delivery technologies and protect our products from competition. As of May 4, 2007, we had 12 published pending U.S. patent applications, 15 unpublished pending U.S. patent applications, one published pending Patent Cooperation Treaty, or PCT, application, five unpublished pending PCT Applications, 38 published pending foreign applications, four unpublished pending foreign applications and one issued Irish patent covering our thin film drug delivery technology. Our total number of patents and pending patent applications, including unpublished applications from all categories, exceeds 75.

Prior to partnering with us, our pharmaceutical company partners perform due diligence on our intellectual property portfolio. This due diligence typically consists of establishing our "freedom to operate." The process of establishing "freedom to operate" consists of determining whether a product using our thin film drug delivery technology can be marketed without infringing the valid rights of third parties, and a qualitative assessment of our future ability to create intellectual property-based barriers to competition from third parties.

A "freedom to operate" analysis generally includes a review of all known issued patents, as well as a review of known published pending art in the field. We believe our partners have reached favorable conclusions with respect to our "freedom to operate." We do not believe that our existing products and product candidates infringe upon the valid thin film intellectual property rights of others.

We believe our global portfolio of patent applications is a significant source of competitive advantage. Our applications seek to cover our product compositions, our use of encapsulation for tastemasking, our manufacturing process, and certain novel packaging embodiments. We believe our most critical patent applications are those that relate to our ability to effectively mask the taste of the drug formulations incorporated into our thin film and to manufacture film in which the drug is uniformly dispersed.

Adoption of our thin film technology depends on our ability to successfully mask the often bitter and poor taste of drug formulations. To achieve this end, we are seeking certain patent claims covering the use of drug encapsulation for tastemasking in thin film products. Encapsulation refers to the coating of drug particles with a polymeric covering sufficient to help mask the taste of the drug particle while maintaining the ability to release the drug for absorption in the stomach. Encapsulation is an efficient method for combining a high ratio of drug to non-drug elements in the tastemasked particle. In fact, we have been able to incorporate as much as 60% drug by mass in our encapsulations. This allows us to deliver high drug loads in a single film. We believe we are the first and only company to commercially apply encapsulation technology in thin film.

We believe the only commercially available alternative to encapsulation for tastemasking is the use of an ion exchange resin to bind the drug, forming a resinate that is less bitter than the drug alone, which then releases the drug in the stomach. The use of ion exchange resins for tastemasking has four significant challenges for its application to thin film. First, ion exchange resins are limited in their application to tastemask drugs due to the specificity of their chemistry. Second, the percentage of drug to non-drug elements in an ion exchange resinate tends to be fairly low, approximately 15-40% and is highly dependent on the drug. This means that the thin film needs to deliver a fairly large amount of resinate relative to the amount of drug that is delivered, thereby reducing the amount of drug which can be delivered by a single thin film dose. Third, ion exchange drug resinates form a new drug salt which may necessitate more extensive safety and clinical investigations to obtain marketing approval from global regulatory authorities. Fourth, a patent covering the use of certain ranges of ion exchange resins for tastemasking in thin film was issued in June 2006 to Pfizer Consumer Health (US Patent 7,067,116). Unless Pfizer Consumer Health is willing to license its technology, it will be difficult for parties other than Pfizer Consumer Health to use ion exchange technology for thin film.

We are also seeking patent protection for our "mother daughter" mixing system technology. In this system, a main batch of water-based coating solution is prepared in the "mother" tank. This solution is then pumped into a "daughter" tank where the tastemasked (encapsuled) active drug is mixed in, and then applied onto a backing paper on which it is dried into film. While one fully mixed daughter tank is being used to feed the coating system, the second daughter tank is charged with drug and polymer and fully mixed. The system is designed to provide a continuous batch coating process of a uniform dispersion thereby minimizing the residence time of the drug active (or encapsulated drug active where encapsulation is used) in the water-based coating solution prior to making film thus maintaining the integrity of the encapsulation. We believe this mixing technology is critically important to enable the use of tastemasked drug encapsulations in thin film, the capability to process some sensitive drugs that may tend to degrade over time in an aqueous environment and the ability to maintain uniform film performance at large batch scales. This translates into film with better and more consistent tastemasking. It also allows us to be more efficient in our manufacturing process and ensures consistent drug release as compared to films containing encapsulated drug manufactured without this system.

Content uniformity is a requirement for all solid dosage forms. We need to maintain uniform dispersion of drug in our coating solution, during the application of the coating solution to the substrate, and during the ensuing drying process. We also have certain patent applications relating to our controlled film drying process, and the use of bottom drying in the initial stages of the film drying process. We believe that our process of controlled drying is critical to maintaining content uniformity of the drug during the drying process.

Collectively, we believe our extensive global portfolio of patent applications covering our compositions, methods of manufacture, particularly as they relate to tastemasking and uniformity, and other critical aspects of our thin film drug delivery technology have the potential to create significant barriers to entry for potential competitors.

In addition to our patent strategy, we use trade secrets, know how and continuing technological innovation to develop and maintain our competitive position. The development of our technology and many of our processes are dependent upon the knowledge, experience and skills of key scientific and

technical personnel. We have employment and/or consulting agreements in place with all of our principal inventors. We require all employees, consultants and advisors to enter into confidentiality agreements that prohibit the disclosure to or use of confidential information by any third party and which assign any invention rights to us. Further, as a matter of company policy, all scientific and technical employees have executed agreements that generally require disclosure and assignment to us of discoveries and inventions made by these individuals while devoted to our activities.

Manufacturing and Production

We currently manufacture film strip products in our current good manufacturing practices, or cGMP, manufacturing facility in Portage, Indiana. Our Portage facility has a bulk film production capacity of approximately 750 million strips per year. Our Portage facility has successfully passed pharmaceutical and governmental audits, including a food inspection by the FDA and a pharmaceutical inspection by the Australian Therapeutic Goods Administration, or the Australian TGA. Our Portage facility is registered with the Drug Enforcement Administration, or DEA, for Class III-V drugs. We also have a research and development laboratory in Kingsport, Tennessee. The Kingsport facility is registered with the DEA for Class II-V drugs. We believe that our current production capacity is sufficient to meet our present output requirements.

In October 2006, we entered into an agreement to lease the Ameriplex facility, a cGMP facility also in Portage, Indiana. Once retrofitted and approved, the Ameriplex facility will become our primary research, development, manufacturing and warehouse location. The Ameriplex facility provides us with the needed space for additional coating lines to meet future expected demand. The new facility and equipment give us greater control and operating efficiency for the products we produce.

In January 2007, we engineered and placed an order for a new second film manufacturing line to fulfill a long term customer supply agreement. The new line will have a maximum capacity of nearly 2.2 billion strips per year. Additionally, we own another smaller film manufacturing line that we intend to upgrade and validate for pharmaceutical products in 2008. We expect that the existing facility, the Ameriplex facility, the additional production capacity and the outsourcing relationships we presently have will allow us to meet our supply requirements for at least the next three years.

The various regulatory requirements to which we are subject, such as the regulations of the FDA, the DEA and the TGA, require us to adhere to cGMP. This standard requires manufacturers to follow elaborate design, testing, control, documentation and other quality assurance procedures throughout the entire manufacturing process. Our facility has undergone a food inspection by the FDA, a DEA inspection, a TGA drug inspection, and a number of quality and assurance inspections by pharmaceutical companies for cGMP compliance. In each case, our facility has passed inspection. At some point in the future, we will undergo a pharmaceutical inspection by the FDA as well. We are also subject to periodic re-inspection of our facilities.

We purchase our raw materials from qualified, approved vendors both domestically and internationally. We only have two "sole supplier" agreements and typically source raw materials from the lowest cost provider whenever possible. We expect that we will enter into more formal and predictive supply agreements in the future as production volumes increase and are more predictive. Additionally, we purchase active pharmaceutical ingredients from various suppliers in cases where such ingredients are not supplied by our pharmaceutical company partners.

Government Regulation

Our operations are subject to regulation by the federal government, state governments, and certain foreign governments. The Federal Food, Drug, and Cosmetic Act, or FDCA, other federal statutes and regulations, various state statutes and regulations, and laws and regulations of foreign governments govern to varying degrees the testing, approval, production, labeling, distribution, post-market surveillance, advertising, dissemination of information, and promotion of our products. The lengthy process of laboratory, animal and clinical testing, data analysis, manufacturing development, and

regulatory review necessary for required governmental approvals is costly and uncertain, and can delay or prevent product introductions in a given market. Promotion, marketing, manufacturing, and distribution of pharmaceutical products are regulated in all major world markets.

The FDA's regulatory control of product approval directly affects our ability to launch our products in the United States market even though some OTC pharmaceutical products can be launched without the need for FDA product approval. These products are a subset of OTC products, which may be marketed without a specific FDA approval if they conform to a special published regulation of the FDA referred to as an OTC monograph.

OTC Products

OTC products are those that are available to consumers without a prescription. They are available to consumers without a prescription because they can be labeled for safe and effective use without the supervision of a physician or other professional healthcare provider. In the United States, the FDA establishes OTC drug monographs for particular product classes, such as cough and cold products. The monographs specify permissible active ingredients, labeling and indications. Products that conform to a monograph may be marketed without a specific FDA approval. OTC products that do not conform to an OTC monograph generally require review and approval through a new drug application, or NDA, abbreviated new drug application, or ANDA, or 505(b)(2) application.

Prescription Drugs

Most prescription drugs marketed in the United States must be approved by the FDA before they can be lawfully marketed. In the case of an existing prescription drug that has already been approved by the FDA, the FDA will likely need to grant a separate and additional approval if the drug is to be marketed in a new film dosage form. Comparable requirements exist in other countries.

NDA Process

For innovative, or non-generic, new drugs, an FDA approved NDA is generally required before the drugs may be marketed in the United States. The NDA must contain data to demonstrate that the drug is safe and effective for its labeled uses, and that it will be manufactured to appropriate quality standards. In order to demonstrate safety and effectiveness, an NDA typically must include or reference pre-clinical data from animal and laboratory testing and clinical data from controlled trials in humans. For a new chemical entity, this generally means that lengthy, uncertain and rigorous pre-clinical and clinical testing must be conducted. For compounds that have a record of prior or current use, it may be possible to utilize existing data or medical literature and limited new testing to support an NDA.

Any pre-clinical laboratory and animal testing must comply with the FDA's good laboratory practice and other requirements. In order to initiate a clinical trial, the sponsor must submit an investigational new drug application, or IND, to the FDA or meet one of the narrow exemptions that exist from the IND requirement. Clinical testing in human subjects must be conducted in accordance with the FDA's good clinical practice and other requirements.

The process leading up to the filing of the NDA presents a number of challenges. The FDA may refuse to accept the IND for review if applicable regulatory requirements are not met. Moreover, the FDA may delay or prevent the start of clinical trials if the manufacturing of the test drugs fails to meet cGMP requirements or the clinical trials are not adequately designed. Such government regulation may delay or prevent the study and marketing of potential products for a considerable period of time and may impose costly procedures upon a manufacturer's activities. In addition, the FDA may, at any time, impose a clinical hold on ongoing clinical trials. If the FDA imposes a clinical hold, clinical trials cannot continue without FDA authorization and then only under terms authorized by the FDA.

Success in early-stage clinical trials does not assure success in later-stage clinical trials. Results obtained from clinical activities are not always conclusive and may be susceptible to varying interpretations that could delay, limit or prevent regulatory approval. Even if a product receives regulatory approval, later discovery of previously unknown problems with a product may result in restrictions on the product or even withdrawal of the marketing approval for the product.

Clinical trials involve the administration of the investigational drug to people under the supervision of qualified investigators. Clinical trials must be conducted under protocols detailing the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. These protocols are submitted to the FDA as part of the IND.

An independent institutional review board, or IRB, must review and approve each trial before it can begin, and these trials must be deemed adequate and well controlled to determine the safety and efficacy of the drug for each indication. Clinical trials are typically conducted in three sequential phases, but the phases may overlap or be combined. Phase I includes the initial introduction of an IND into a small number of humans. These trials are closely monitored and may be conducted in patients, but are usually conducted in healthy volunteer subjects. These trials are designed to determine the metabolic and pharmacologic actions of the drug in humans and the side effects associated with increasing doses as well as, if possible, to gain early evidence on effectiveness. Phase II usually involves trials in a limited patient population to evaluate dosage tolerance and appropriate dosage, identify possible adverse effects and safety risks and preliminarily evaluate the efficacy of the drug for specific indications. Phase III trials are large trials used to further evaluate clinical efficacy and test further for safety by using the drug in its final form in an expanded patient population. There can be no assurance that we will successfully complete Phase I, Phase II or Phase III testing within any specified period of time, if at all. Furthermore, clinical trials may be suspended at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk.

The FDA can, and does, reject new drug applications, require additional clinical trials, or grant approvals on only a restricted basis even when product candidates performed well in clinical trials. The FDA regulates and typically inspects manufacturing facilities, equipment and processes used in the manufacturing of pharmaceutical products before granting approval to market any drug. Each NDA submission requires a substantial user fee payment, unless a waiver or exemption applies. The FDA has committed generally to review and make a decision concerning approval on an NDA within 10 months, and on a new priority drug within six months. However, final FDA action on the NDA can take substantially longer, and where novel issues are presented there may be review and recommendation by an independent FDA advisory committee. The FDA can also refuse to file and review an NDA it deems incomplete or not properly reviewable.

ANDA Process

In the United States, generic drugs are approved through an abbreviated process based on the submission to the FDA of an ANDA. The ANDA must seek approval of a drug product that has the same active ingredient(s), dosage form, strength, route of administration, and labeling as a so-called "reference listed drug" approved under an NDA, although some limited exceptions may be permitted. For example, an applicant may file a suitability petition with the FDA seeking the agency's approval to file an ANDA for a different dosage form of a drug than the dosage form in the existing reference listed drug. Under the FDA's regulations, the agency will not grant a suitability petition for a change in dosage form if clinical testing would be needed to establish the safety and efficacy of the change. The FDA has previously determined that an applicant could submit an ANDA for famotidine 10 mg (marketed under the brand name Pepcid AC®) in an orally dissolving strip formulation where the reference listed drug is a chewable tablet. In the case of a prescription drug that is currently marketed in a quick dissolve dosage form, management believes, based upon informal discussions with the FDA's

Office of Generic Drugs, that it will be able to file an ANDA for approval of a film dosage form. We can give no assurance, however, that the FDA will make similar determination for our products.

An ANDA generally must contain limited clinical data to demonstrate that the product covered by the ANDA is absorbed in the body at the same rate and to the same extent as the reference listed drug. This is known as bioequivalence. In addition, the ANDA must contain information regarding the manufacturing processes and facilities that will be used to ensure product quality, and must contain certifications to patents listed with the FDA for the reference listed drug. An ANDA may not be approved if the reference listed product is subject to applicable periods of market exclusivity, or if there are valid patents other than manufacturing (process) patents covering the reference listed drug for the ANDA. Special procedures apply when an ANDA contains certifications stating that a listed patent is invalid or not infringed, known as a Paragraph IV certification. If the owner of the patent or the NDA for the reference listed drug brings a patent infringement suit within a specified time after receiving notice of a paragraph IV certification, an automatic stay bars FDA approval of the ANDA for a specified period of time pending resolution of the suit or other action by the court.

The amount of testing and effort that is required to prepare and submit an ANDA is generally substantially less than that required for an NDA. ANDAs typically go through two review cycles at the FDA. The median time to approval can vary, but is likely to approximate 15-18 months.

The first applicant to have an ANDA accepted for filing by the FDA that includes a Paragraph IV certification is awarded a 180-day period of marketing exclusivity. This means that the FDA may not approve another ANDA for that product until the first developer's 180-day period of marketing exclusivity has expired or has been waived. Under current law, the 180-day marketing exclusivity period generally begins with the first commercial marketing of the product, although the exclusivity can be forfeited by failure to market within specified timelines and certain other events, and some products are subject to prior rules under which the 180-day period is triggered by a court determination that the relevant patents are invalid, unenforceable or not infringed.

505(b)(2) Applications

We currently intend to seek approval of our film versions of drugs that are currently approved in non-rapid dissolve dosage forms by using a type of an NDA referred to as a "505(b)(2) application." Under section 505(b)(2) of the FDCA, 505(b)(2) applications may rely, in whole or in part, on safety or efficacy data that the applicant does not have a right to reference. For example, the applicant can cite published medical literature without a right to reference the underlying study data involved. Under current FDA regulations and policies, 505(b)(2) applications can also be used where the applicant is relying on prior FDA findings of safety or effectiveness regarding another company's NDA but does not qualify for the ANDA process because of some change being made for the new product relative to the existing products. For example, an applicant may seek FDA approval under section 505(b)(2) of a controlled-release formulation of an approved immediate-release formulation of another company. The 505(b)(2) applicant would reference in its application the immediate-release formulation, and submit new data to support the change to a controlled-release formulation. The 505(b)(2) application process may significantly reduce the time and expense of new drug development by eliminating the need for certain duplicative testing.

505(b)(2) applicants must make patent certifications with respect to any reference listed drug in the same manner as ANDA applicants, and the 505(b)(2) applications are also subject to any market exclusivity periods covering a reference listed drug. These patent and market exclusivity protections on products referenced in a 505(b)(2) application may result in the lengthy and uncertain delays of approvals similar to those described above for ANDAs. In addition, there is ongoing debate around the legality of the FDA's interpretation of section 505(b)(2) to permit an applicant to rely upon prior FDA findings with respect to another company's application. If there is a legal challenge to the FDA's

interpretation and the agency's view is invalidated, there would be new limitations on an applicant's ability to use the 505(b)(2) application process rather than conducting its own substantial clinical testing.

Post-Marketing Requirements

The FDA continues to review marketed products after approval or issuance of an OTC monograph. If previously unknown problems are discovered or if there is a failure to comply with applicable regulatory requirements, the FDA may restrict the marketing of a product, cause the withdrawal of the product from the market, or under certain circumstances seek recalls, seizures, injunctions or criminal sanctions. For example, the FDA may require labeling changes or additional studies for any marketed pharmaceutical product if new information reveals questions about a drug's safety or effectiveness. In addition, in the case of a product subject to an NDA, ANDA, or 505(b)(2) application, changes to the product, the manufacturing methods or locations, or labeling are subject to additional FDA approval, which may or may not be received, and which may be subject to a lengthy FDA review process.

Whether marketed under an approved application or an OTC monograph, all drugs must be manufactured in conformity with cGMP and other FDA regulations and requirements, and pharmaceutical products subject to an approved application must be manufactured, processed, packaged, labeled and promoted in accordance with the approved application. Certain products must also be packaged with child-resistant and senior friendly packaging under the Poison Prevention Packaging Act and Consumer Product Safety Commission regulations. Products that do not comply with these requirements can be considered misbranded and subject to seizure, recall, monetary fines, and other penalties. We must comply with cGMP and product specific regulations enforced by the FDA, and are continually subject to inspection by the FDA and other governmental agencies. Manufacturing operations could be interrupted or halted in any of those facilities if a government or regulatory authority determines that our contract manufacturers do not comply with applicable regulations or as a result of an unsatisfactory inspection.

The distribution of prescription pharmaceutical products is also subject to the Prescription Drug Marketing Act, or PDMA, which regulates the distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states. States require the registration of manufacturers and distributors who provide pharmaceuticals, including in certain states even if these manufacturers or distributors have no place of business within the state but satisfy other nexus requirements, for example, the shipment of products into such state. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples to licensed practitioners and impose other requirements to ensure accountability in the distribution of samples.

Other reporting and recordkeeping requirements also apply for marketed drugs, including for most products requirements to review and report cases of adverse events. Product advertising and promotion are subject to FDA and state regulation, including requirements that promotional claims conform to any applicable FDA approval, and be appropriately balanced and substantiated. OTC drug advertising is also regulated by the Federal Trade Commission. Sales, marketing and scientific/educational programs must comply with applicable requirements of the anti-kickback provisions of the Social Security Act, the False Claims Act, the Veterans Healthcare Act, and the implementing regulations and policies of the United States Health and Human Services Office of Inspector General and United States Department of Justice, as well as similar state laws. Pricing and rebate programs must comply with applicable pricing and reimbursement rules, including the Medicaid drug rebate requirements of the Omnibus Budget Reconciliation Act of 1990. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

Other Regulatory Requirements

In addition to the statutes and regulations described above, we are also subject to regulation under the Occupational Safety and Health Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and other federal, state and local regulations. We believe that we have complied with these laws and regulations in all material respects, and we have not been required to take any action to correct any material noncompliance. We are unable to predict, however, the impact on our business of any changes that may be made in these laws or of any new laws or regulations that may be imposed in the future. We cannot be sure that we will not be required to incur significant compliance costs or be held liable for damages resulting from any violation of these laws and regulations.

Sales And Marketing

We market directly to leading pharmaceutical companies for products that we believe would benefit from our thin film drug delivery technology. Our strategy has been to leverage the brand equity, clinical, regulatory, marketing and sales capabilities of these pharmaceutical companies to maximize the value of our thin film drug delivery technologies. We will continue to build our credibility with major pharmaceutical companies by speaking at technical seminars, publishing in technical journals and exhibiting at pharmaceutical and drug delivery conferences.

We pursue feasibility or pilot agreements with leading pharmaceutical companies who fund the development of new products incorporating our drug delivery technologies. If the new product development is successful, we generally enter into licensing and supply agreements.

Partner Agreements

We have a number of partner agreements for the development of prescription and OTC thin film drug targets and the commercial supply of products including certain specialty non-pharmaceutical thin film applications. We have generally structured our partner agreements in the framework that is common to the rapid dissolve drug delivery market. Typically, a partner engages us to develop a particular product using specific active ingredients and, where appropriate, apply tastemasking and incorporate flavors. These arrangements are milestone-based and require payment by the partner as each particular milestone is achieved. Once development is underway, we negotiate a long-term commercial supply and licensing agreement with the partner. Revenue is realized under those agreements through the amount paid to us for product supply as well as through royalties. The royalties are calculated as a percentage of product sales. For the years ended December 31, 2006, 2005 and 2004 most of our partners were principally located in the Northeastern and Southeastern parts of the United States.

We believe that the financial terms we have agreed upon with partners are in line with comparable transactions in the rapid dissolve drug delivery market. We believe we are able to attract certain higher value partnerships than traditional rapid dissolve transactions in certain cases because some of our partnerships involve new therapeutic products or total product replacements (i.e. moving an entire product into thin film). In contrast, rapid dissolve technologies have traditionally been limited to line extensions where a company sells a rapid dissolve tablet at the same time it offers a traditional tablet version (e.g. Schering Plough's Claritin® is sold as both a conventional tablet and as a rapidly dissolving Reditab). In 2006, Philip Morris USA, King Pharmaceuticals, Leiner Health Products and Warner Chilcott each accounted for more than 10% of our revenues.

Adams Respiratory Therapeutics, Inc. In March 2007, we entered into development, supply and licensing agreements with Adams Respiratory Therapeutics, Inc., or Adams, for a prescription respiratory product. The development agreement includes a work plan for the initial product, which is a thin film containing a respiratory product, and contemplates that the parties may agree on additional products to be developed under the terms of the development agreement. The development milestones

for the respiratory product from development through commercial launch total $1.5 million. In addition, Adams agrees to pay $167,000 on each of the second, third and forth anniversaries of commercial launch. The development agreement also contains rights of first refusal for certain drugs that we or Adams may develop in the future. Pursuant to this right of first refusal, if we develop one of these pharmaceutical products, Adams will have the first right to exclusively market them in the United States. Likewise, if Adams desires to develop one of these drug products, we will have a right of first refusal to develop and manufacture them in the United States. These rights of first refusal are conditioned upon the development of a second thin film product, on terms to be negotiated, within 180 days following the proof of concept bio-study for the respiratory product, but in any case not before the calendar year 2008. In addition to other representations and warranties, we represent in the development agreement that our performance will not, to the best of our knowledge, infringe or otherwise conflict with the intellectual property rights of third parties. The development agreement is for a seven-year term, covers the United States, Canada and Mexico and may be extended at Adams' election for up to three three-year extension terms. In certain circumstances both we and Adams may cancel the development agreement before the term expires. We have agreed to develop the respiratory film product exclusively for Adams.

Our supply agreement with Adams contains standard terms and conditions, and is also for a seven-year term, which may be extended by Adams for up to three three-year extension terms.

Our license agreement with Adams has the same term as the supply agreement, including the same right to extend by Adams, but will remain in effect for an additional seven years in the event Adams terminates the agreement for our breach. The license agreement only applies to the respiratory thin film product. Adams agrees to pay royalties for the respiratory product on annual net sales within the territory of: 5% for the first $15 million in net sales; 6% on net sales from $15 to $25 million; 7% on net sales from $25 to $35 million, and 7.5% on all net sales over $35 million. In the event that a competitor obtains an approval for a competing, "AB"-rated product, our royalty rates are subject to reduction in accordance with a formula based upon the percentage decline in net sales of the product we make. Such a reduction could be material. Adams may terminate the license agreement upon 30 days' notice.

UMD Inc. UMD Inc., or UMD, has engaged us on a purchase order basis to develop a dual film system to vaginally deliver an active ingredient. To date, UMD has paid us $166,664 for formulation development and the manufacture of clinical supplies, contracted for on a purchase order basis. This product has undergone in vivo testing with favorable results. We are currently negotiating follow-on development work with UMD.

Philip Morris USA Inc. In February 2007, we entered into a five-year strategic exclusive supply agreement with Philip Morris USA Inc., or Philip Morris, for the supply of specialty application film strips for use in certain tobacco products. Subject to the agreement terms, Philip Morris has agreed to purchase all of its requirements for specialty application film strips for those tobacco products from us. In return, we agree to supply all of Philip Morris's requirements up to the amount of the capacity for our new production line which we have agreed to deploy in connection with our entry into this agreement. Philip Morris can terminate the agreement if we fail to meet certain service levels. Philip Morris may also terminate our strategic supply agreement if a change in control, including certain changes in the composition of our board of directors occurs. We have made certain representations and warranties to Philip Morris, including that the specialty application film strips we provide will not infringe upon the intellectual property rights of third parties.

Medtech Products Inc. In October 2006, we entered into a development agreement with Medtech Products Inc., or Medtech, a subsidiary of Prestige Brands Holdings. Pursuant to this agreement, we will develop three thin film product prototypes. During this development phase the agreement requires Medtech and us to negotiate a five-year commercial supply agreement, pursuant to which we will agree

to supply all of Medtech's requirements for a benzocaine sore throat product, which Medtech will agree to exclusively purchase from us.

L. Perrigo Company. In March 2007, we entered into a development and supply agreement with L. Perrigo Company, or Perrigo. Under this agreement, we are to develop and supply a thin film product containing Diphenhydramine HCI, a cough medication, and will receive payments upon reaching preformulation, pilot stability, and scale-up milestones. This product will be a national brand equivalent to an existing, branded thin film product, and will be exclusive to Perrigo for store brand marketing in the United States and Canada. The initial term of the agreement extends through December 31, 2011.

CNS, Inc.—GlaxoSmithKline plc. We developed an anti-snore thin film product for CNS, Inc. prior to its acquisition by GlaxoSmithKline plc, on a purchase order basis, and have received payments of $290,870 to date for such development. We have received a purchase order for product launch quantities and are currently negotiating a global supply agreement for the product.

Aziende Chimiche Riunite Angelini Francesco A.C.R.A.F. S.p.A. In April 2006, we entered into a development agreement with Aziende Chimiche Riunite Angelini Francesco A.C.R.A.F. S.p.A., or Angelini, to develop a thin film product containing benzydamine, a sore throat medication. The initial work order is for $40,000 in development work, of which $20,000 has been paid to us.

Dr. Harold Katz LLC. In June 2004, we entered into a four-year exclusive agreement with Dr. Harold Katz LLC to supply breath strips to Dr. Harold Katz LLC and its affiliates, together, TheraBreath. This agreement has an initial term of four years, with automatic one year extensions unless one party notifies the other of its intent to cancel within three months of the extension. We also supply TheraBreath with a vitamin product on a purchase order basis.

Vita Health Products, Inc. In June 2006, we entered into a development and supply agreement with Vita Health Products, Inc. of Canada, or Vita. Under this agreement, we have agreed to supply two OTC thin film products to Vita for sale in the Canadian market. Vita is responsible for registering the products in Canada. In 2007, we received initial purchase orders from Vita for the two products. The initial term of the agreement is five years.

C.B. Fleet Company, Inc. We are developing a thin film OTC product for C.B. Fleet Company, Inc., or Fleet, on a purchase order basis. We also entered into a non-binding term sheet with Fleet in April 2007 which includes terms for the supply and license of this thin film product. Under these terms, we will receive a royalty of 3% to 6% of net sales, our royalty percentage increasing as certain sales volumes are reached, and we will sell the product exclusively to Fleet on a global basis, except for the Middle East and North Africa. Under the non-binding term sheet, Fleet also has the exclusive right to develop a second thin film product for a limited time period. We are working with Fleet on a definitive agreement based upon the non-binding term sheet.

Certain Undisclosed Pharmaceutical Partners. In December 2006, we entered into a development agreement with a mid-sized global pharmaceutical manufacturer for a thin film that will bucally deliver certain controlled prescription actives. Under this agreement, we will receive payments upon meeting four different development milestones during the term of the agreement. This agreement has a term of 9 months, unless extended by the customer upon four weeks' notice

In August 2006, we entered into an agreement to develop a thin film that will sublingually deliver certain prescription actives. We have successfully completed preliminary formulation work and demonstrated our ability to achieve acceptable organoleptic performance and content uniformity at a very low drug loading level (i.e., micrograms). This product, should development continue, would entail the submission of a new drug application and will ultimately require dedicated manufacturing. This agreement may be terminated by either us or the customer upon 30 days' notice.

Employees

As of April 23, 2007, we had 63 employees (not including contract and temporary workers). Of these employees, four hold Ph.D. degrees. With the exception of one employee, all of our employees are full-time; 20 of these are directly involved in research and development, and approximately 31 are involved in manufacturing operations, including regulatory affairs.

We are subject to local labor laws and regulations with respect to our employees in those jurisdictions. These laws principally concern matters such as paid annual vacation, paid sick days, length of the workday and work week, minimum wages, pay for overtime, and insurance for workers' compensation.

Our employees are not represented by a labor union. We do not have written employment contracts with most of our employees, and we believe that our relations with our employees are satisfactory.

Facilities

We currently lease an approximately 10,000 square foot facility, including offices, in Portage, Indiana, which houses our research and development, analytical labs and cGMP manufacturing operations. This facility currently has the capacity to produce approximately 1 billion thin film strips per year. Our lease on the Portage facility was entered into in February 2002 and expires (including renewals) in 2010, at which time we have the right to purchase the facility for approximately $1.3 million. Our current monthly rent for this facility is $14,304.

We also lease a 400 square foot technology development laboratory in a multi-tenant facility in Kingsport, Tennessee, which is registered with the DEA for Class II-V drugs. The lease was entered into in January 2003 and expires December 31, 2009. Our monthly rent for this facility is currently $1,300.

We currently lease our 4,140 square-foot headquarters office in Warren, New Jersey. The office is located in a large, multi-tenant technology center. We plan to upfit 600 square feet of this space for laboratory use in 2007. The lease for this facility commenced in July 2006 and expires in 2011. Our monthly rent for this facility is currently $7,859.

We also are guarantor of a lease for approximately 1,000 square feet of office space in Washington, D.C. The underlying lease was entered into by one of our consultants and expires in May 2007. This space is used as our business development office. We have agreed to extend the lease on a month to month basis.

We also entered into an agreement to lease the 73,000 square foot Ameriplex facility. The lease and renewal options expire in 2021 and also contain a "right of first refusal" option on any potential sale of the property. The rent for the first 18 months of the lease is approximately $33,500 per month.

Legal Proceedings

We are not currently a party to any material legal proceedings. We may, from time to time, become involved in litigation or other adversarial proceedings based on commercial, product liability or other claims.

Compensation Committee Interlocks And Insider Participation

None of the members of our compensation committee was at any time during 2006 one of our officers or employees. No member of our compensation committee and none of our executive officers serve as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee.

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Objectives

The primary objective of the compensation committee of our board of directors with respect to executive compensation is to attract, motivate and retain the best possible executive talent. Further, we believe that compensation should support our business goals and encourage increased stockholder value. These objectives govern the decision making process with respect to the amount and type of compensation payable to our executive officers. We expect to further implement and maintain, compensation plans that link executive compensation to the achievement of key strategic goals such as the level of earnings and new product commercialization. We believe that this will better align compensation with stockholder value. The compensation program is designed to reward the attainment of both company goals and individual goals.

Compensation Setting Process

Total compensation levels for each of our named executive officers are evaluated on an annual basis. In the past, our predecessor company, Monosol Rx LLC and its manager's general partner set compensation levels for each of our named executive officers. In the future, our compensation committee will set compensation with input from our chief executive officer.

During 2006, our manager's general partner relied on publicly available compensation data to establish compensation for our executive officers. As a startup company with significant operating losses, in order for us to attract highly skilled and experienced executive officers and managers, we aggressively bid for candidates in certain situations. In these cases, compensation was determined by industry norms, an individual's current compensation and a compensation premium that would be sufficient enough to attract that individual to work for us. In each of these cases, the manager's general partner and members of our advisory board were an integral part of setting each individual's executive compensation.

Following the completion of our initial public offering, our compensation committee expects to establish a benchmark group of companies in the life sciences and pharmaceutical industries that are similar to us in terms of stage of development, size, locations and/or job type. The benchmark group would also be representative of the types of companies we would compete with for executives and other employees.

Each of our named executive officers is a party to an employment agreement with us that sets forth certain elements of their respective compensation, including base salary. Please see the narrative discussion following the Grants of Plan-Based Awards table for additional information on the employment agreements with our named executive officers.

Compensation Components

Our executive compensation program includes the following five components:

•: Base Salary
•: Discretionary Annual Bonus
•: Long-Term Incentives
•: Employee Benefits and Perquisites
•: Severance and Change in Control Benefits

Base Salary

Base salaries for each of our named executive officers, including our chief executive officer, are determined pursuant to the terms of their individual employment agreements. Base salaries are based

on the scope of their responsibilities, taking into account competitive market compensation paid by other companies for similar positions to ensure that we are able to attract and retain quality candidates. The general partner of our manager has in the past and our compensation committee may in the future have the discretion to increase the base salary of the chief executive officer from time to time, based upon such factors that include, but are not limited to, performance and market levels. Generally, the chief executive officer may increase base salaries of the other named executive officers from time to time in his discretion, based upon such factors that include, but are not limited to, performance and market levels. Please see the narrative discussion following the Grants of Plan-Based Awards Table for additional information on the employment agreements.

Discretionary Annual Bonus Opportunity

Our executive officers are eligible for annual discretionary bonuses designed to reward the achievement of corporate financial and operational goals, as well as individual performance objectives. Bonus targets are expressed as a percentage of the executive's base salary, as provided in our named executive officers' respective employment agreements. Like our base salaries, the bonus targets set forth in the employment agreements were based on the scope of a named executive officer's responsibilities, taking into account competitive market compensation paid by other companies for similar positions to ensure that we are able to attract and retain quality candidates. Our manager's general partner has in the past and our compensation committee will in the future have the discretion to increase or decrease the bonus above the target percentage of an executive officer's bonus based on the performance of the individual against company and individual goals.

The manager's general partner has in the past and our compensation committee will in the future approve the annual bonus award for the chief executive officer, and for each officer below the chief executive officer level, the bonus award is based on the chief executive officer's performance assessment of each officer. Typically, the bonus is paid in a single installment in the first quarter following the completion of a given fiscal year. Depending on the terms of the executive officer's employment agreement, a portion of a named executive officer's bonus may be granted in performance units of the company. Please see the narrative discussion following the Grants of Plan-Based Awards Table for additional information on the employment agreements.

Generally, the employment agreements with our named executive officers provide that eligibility for discretionary bonuses is tied to the achievement of company performance targets. In practice, we have taken both company and individual achievement into account. In the past, in setting and assessing company and individual performance, we have not used a predetermined formula or weighted factors. Our company achievement objectives generally relate to the growth of our business and the development of a company infrastructure to support the activities related to that growth. In 2006, our corporate focus was on revenues, customer development, product development and employee skill development. In 2006, the individual objectives generally related to either financial factors such as cash management and capital raising or strategic factors such as pre-clinical and clinical development, regulatory approval of our product candidates and management of our manufacturing operations in meeting cost targets and demand levels for our product and product candidates. The amount of emphasis put on each individual achievement depends on the individual's role within our company. The manager's general partner of our predecessor also took into account an individual's tenure, position, performance and responsibilities in approving the 2006 bonuses. For the chief executive officer, overall company performance is used to evaluate his individual performance.

The level of company and individual achievement is monitored by the chief executive officer and other executive officers on an ongoing basis throughout the year. At the end of the year, as part of each executive officer's evaluation and compensation review, each executive officer's achievement, as well as the executive's contribution to corporate performance, is assessed. The manager's general

partner has in the past and our compensation committee will in the future assess the performance of the chief executive officer.

From time to time, special bonuses may be granted in order to attract highly qualified and talented executives. In 2006, Mr. Kendall received a one-time signing bonus when he joined us.

In 2006, the following discretionary bonuses were earned by our named executive officers.

Executive Officer	Position	Actual Bonus Amount Paid		Target Bonus (% of Base Salary)
A. Mark Schobel	President, Chief Executive Officer	$	227,500	50	%
Keith Kendall*	Executive Vice President, Chief Financial Officer	$	158,438	75	%
Joseph Fuisz*	Senior Vice President, Business Development and Licensing	$	44,660	50	%
Dr. Pradeep Sanghvi**	Vice President of Pharmaceutical Development	$	64,064	50	%
Carl Fischer	(former Chief Financial Officer) current Senior Director, Finance	$	32,813	25	%

*: These officers joined the company during 2006 and their bonus amounts are pro rated based upon their date of hire.
**: Dr. Sanghvi received a pro-rated bonus based upon his eligibility and base salary change under the terms of his employment agreement.

Please refer to the Summary Compensation Table set forth herein for additional information.

For 2007, the manager's general partner of our predecessor determined that discretionary annual bonus awards for each executive officer should be contingent upon the achievement of company and individual performance targets and established our 2007 goals. We intend to rely more heavily on such company and individual goals and objectives and the measurement of achievement against those goals. We have established a performance management system that outlines the process for setting performance objectives and assessing performance against those objectives. As in the past, these goals continue to generally relate to our growth and continue to emphasize revenues, customer development, product development and employee skill development. Additionally, our individual goals for each executive are in the process of being determined by the chief executive officer and the individual executive, with the oversight and approval of our board of directors. For the chief executive officer, the overall company goals are his individual goals. The individual goals will continue to generally relate to either financial factors such as cash management and capital raising or strategic factors such as pre-clinical and clinical development, regulatory approval of our product candidates and management of our manufacturing operations in meeting cost targets and demand levels for our product and product candidates.

Long-Term Incentives

We believe that long-term performance is achieved through an ownership culture that encourages long-term participation by our executive officers in equity-based awards. Our incentive plans have been established to provide our current and future directors, officers, consultants and advisors, including our executive officers, with incentives to help align their interests with the interests of our stockholders. We believe that the use of equity-based awards offers the best approach to achieve our compensation goals.

In 2006, equity awards were granted under our performance units plan either upon the commencement of employment or due to antidilution measures with respect to previously granted awards. Equity awards have been negotiated on an individual basis with our named executive officers as part of their overall compensation packages. Equity awards have been made to support our compensation objectives of attracting, motivating and retaining executive talent and have been based

upon the scope of a named executive officer's responsibilities, taking into account competitive market compensation paid by other companies for similar positions to ensure that we are able to attract and retain quality candidates.

Performance Unit Plans

Our predecessor, Monosol Rx LLC, maintained and we have assumed two performance unit plans (Plan A and Plan B). The performance unit plans provide for distribution of equity interests, subject to repurchase rights, upon certain terminations of employment or change in control transactions, subject to the satisfaction of applicable vesting conditions. The performance units do not have any value until there is a triggering event, such as a termination or change in control, including an initial public offering. At the time of such a triggering event, all outstanding performance units vest automatically and each participant is entitled to a payment in cash or in the same consideration received by us upon the triggering event. Each participant's awards have been for a specific number of units at our predecessor's then current value, or Base Value. An executive officer with multiple awards often has multiple Base Values. The value of the performance units to a participant is based on the spread between our fair value at the time of a change in control and the Base Value of the performance units the participant has been awarded.

Plan A and Plan B are substantially similar. Mr. Fuisz received a grant of performance units in 2004 which is covered by Plan A. All of his subsequent antidilution grants are covered by Plan B, along with the grants made to each of our other named executive officers.

In 2006, several awards were made under our Plan B performance unit Plan to each of our named executive officers. Mr. Kendall received a grant of awards at the start of his employment pursuant to the terms of his employment agreement. All other awards to our named executive officers were granted as a result of antidilution measures. We hold their respective equity equivalent interests in the fair market value growth of the company stable at the respective percentages to prevent any dilution of those interests prior to this offering. Those percentages are for Mr. Schobel: 4%; Mr. Kendall: 3%; Mr. Fuisz: 4.5%; Dr. Sanghvi: 1% and Mr. Fischer: 0.5%.

During 2006, there were several potentially dilutive events that necessitated grants to each of the executives. These grants were made consistent with the terms of the performance unit plan and at the then current Base Value. Vesting for these units was consistent with the vesting schedule in the performance unit plan or, if applicable, the executive's employment agreement where vesting terms were specifically negotiated. The performance unit plan vesting schedule is as follows:

	Vesting Percentage	Cumulative Vested Percentage
After Year 1	25%	25%
After Year 2	25%	50%
After Year 3	50%	100%

Messrs. Schobel, Kendall and Fuisz have negotiated vesting schedules that vary from the performance unit plan vesting schedule. Mr. Schobel's performance units vest ratably over three years on the anniversary of his hire in December 2005. Mr. Kendall's units vest ratably every six months over three years from the date of his hire in June 2006. Upon the conclusion of the term of Mr. Fuisz's consulting agreement which is anticipated to be in effect upon the expiration of his amended and restated employment agreement, the vesting of his remaining units will accelerate. If Mr. Fuisz's amended and restated employment agreement is terminated for a reason other than his voluntary resignation or his termination for "cause" (as defined in his amended and restated employment agreement), then the vesting schedule of his remaining units will not be affected and will bridge any such break in service. We have entered into a letter agreement with Mr. Fuisz which provides for similar continued vesting in the event his employment with, or his engagement as a consultant by, us is

terminated for a reason other than his voluntary resignation or his termination for "cause" (as defined in Plan A).

In addition, the performance units vest automatically upon a change in control.

In 2006, the following performance units were granted:

Mr. Schobel

•: 02/13/2006—947,203 units at a base value of $39,473,349
•: 03/22/2006—58,820 units at a base value of $39,473,349
•: 06/16/2006—74,032 units at a base value of $87,500,000
•: 10/30/2006—1,583,067 units at a base value of $100,000,000

Mr. Kendall

•: 06/16/2006—3,042,408 units at a base value of $87,500,000

Mr. Fuisz

•: 03/22/2006—443,177 units at a base value of $39,473,349
•: 06/16/2006—83,159 units at a base value of $87,500,000
•: 10/30/2006—1,780,823 units at a base value of $100,000,000

Dr. Sanghvi

•: 03/22/2006—235,280 units at a base value of $39,473,349
•: 06/16/2006—18,254 units at a base value of $87,500,000
•: 10/30/2006—396,527 units at a base value of $100,000,000

Mr. Fischer

•: 02/13/2006—118,654 units at a base value of $39,473,349
•: 03/22/2006—7,099 units at a base value of $39,473,349
•: 06/16/2006—9,127 units at a base value of $87,500,000
•: 10/30/2006—197,757 units at a base value of $100,000,000

No awards have been made in 2007 and we do not expect to make further grants pending the completion of our initial public offering. After the merger of Monosol Rx LLC with MonoSol Rx, Inc. and immediately prior to this offering, the outstanding performance units will be exchanged for the common stock of MonoSol Rx, Inc. We intend to discontinue the performance units plans upon the completion of our initial public offering.

If the value per share of our common stock at the time of the initial public offering is assumed to be $ , we estimate that, immediately before the initial public offering, the aggregate dollar value of the outstanding awards under our performance unit plans will be $ . All unvested performance units shall vest in an amount equal to the Base Value of the grant and the proportional unit value at the time of the initial public offering. The estimated dollar value of the performance unit awards held by each of our named executive officers at the time of the initial public offering are set forth in the following table:

Executive Officer		Value of Performance Plan Units
A. Mark Schobel
Keith Kendall
Joseph Fuisz
Dr. Pradeep Sanghvi
Carl Fischer

Stock Incentive Plan

We anticipate that, before the completion of the initial public offering, our Board will adopt and our stockholders will approve a new stock incentive plan. Approval of our new stock incentive plan by our stockholders before the initial public offering would satisfy the Nasdaq requirement that equity compensation plans receive stockholder approval and consequently, awards that we make under the stock incentive plan after the completion of the initial public offering will not be subject to further vote by our stockholders. We intend to submit the performance criteria under the long-term incentive plan to our stockholders at or before our first annual meeting of stockholders occurring more than 36 months after the completion of the initial public offering in order to meet certain deductibility conditions of the Internal Revenue Code.

The plan is intended to help us (1) optimize our profitability and growth through long-term incentives that are consistent with our goals and that link the interests of participants to those of our stockholders, (2) provide participants with an incentive for excellence in individual and organizational performance, and (3) provide flexibility to help us attract, motivate and retain the services of participants who make significant contributions to our success.

In general, the plan will be administered by our compensation committee. The compensation committee may delegate its authority to persons other than its members, subject to such limitations as may be imposed by the plan or applicable law or stock exchange rules. In general, our compensation committee will decide who will receive awards under the plan and the terms and conditions of those awards, and will have broad discretion regarding the administration and interpretation of the plan and individual awards made under the plan. Our board of directors has the authority to grant awards and to make other determinations under the plan with respect to non-employee directors.

Our compensation committee or the board of directors, as the case may be, will have the authority to grant various types of awards to employees under the plan, including:

•: Stock Options. Each stock option represents the right to purchase a specified number of shares of our common stock at a fixed grant price that cannot be less than the fair market value of the shares on the grant date. The plan does not permit re-pricing of any previously granted stock options. The maximum term of a stock option is 10 years from the date of grant. Any option will be exercisable, if at all, in accordance with terms established by our compensation committee. The purchase price of an option may be payable in cash, shares of our common stock (valued at fair market on the day of exercise), or a combination of both. The plan authorizes our compensation committee to grant non-qualified stock options as well as incentive stock options that comply with the requirements of Section 422(b) of the Code.
•: Stock Appreciation Rights. A stock appreciation right, or SAR, represents the right to receive an increase in the value of a share of our common stock above the value on the date of grant. The maximum term of a SAR is 10 years. A SAR will be exercisable, if at all, in accordance with terms established by our compensation committee. A SAR may be settled in the form of cash or shares of our common stock, as determined by our compensation committee.
•: Restricted Stock and Restricted Stock Units. Restricted stock and restricted stock units represent grants of our common stock or stock units (consisting of the right to receive shares of our common stock in the future) that are subject to a risk of forfeiture or other restrictions that lapse if and when specified service, performance or other objectives prescribed by our compensation committee are achieved. Any awards will be subject to such conditions, restrictions, and contingencies as our compensation committee determines. Restricted stock units are payable in cash, common stock, or a combination of both, as determined by our compensation committee.

•: Other Awards. Our compensation committee will have authority to grant other types of share-based incentive awards that are payable in shares of our common stock or their cash equivalent, including, for example, performance shares, performance units and dividend equivalent rights. In addition, our compensation committee may grant cash incentive awards that are conditioned upon attaining prescribed performance objectives. The compensation committee has the discretion to determine the terms and conditions of any such awards.

Our compensation committee will determine the date on which awards are payable and may permit or require a participant to defer payment of all or a portion of an award subject to conditions established by our compensation committee. If awards are paid in shares of our common stock, our compensation committee will determine whether the shares will be subject to transfer restrictions and/or vesting conditions.

We will be authorized to issue up to shares of our common stock (adjusted for certain capital changes) under the plan. In applying this limitation, we do not count as issued (and thus add back to the plan's share pool): (a) shares covered by awards that expire or are canceled, forfeited, settled in cash or otherwise terminated, and (b) shares delivered to us and shares withheld by us for the payment or satisfaction of purchase price or tax withholding obligations associated with the exercise or settlement of an award. Also, shares covered by stock-based awards assumed by us in connection with the acquisition of another company or business are not taken into account in determining the number of shares that are or may be issued under the plan.

No awards have been granted under the plan. The exact number of future stock options and other awards that may be allocated to any one individual or group of individuals under the plan is not presently determinable.

Unless it is terminated earlier, the plan will remain in effect until all shares subject to the plan have been purchased, acquired, or forfeited, and all cash awards have been paid or forfeited, pursuant to the plan's provisions. However, in no event may an award be granted after 10 years from the effective date of the plan. During the term of the plan, our board of directors may amend or terminate the plan. Any amendment that would cause the plan to fail to comply with any requirement of applicable law, regulation, or rule if it were not approved by stockholders will not be effective unless our stockholders approve the amendment.

Employee Benefits and Perquisites

Consistent with our compensation philosophy to attract and retain talent, we intend to continue to maintain competitive employee benefits and perquisites for all employees, including executive officers.

We currently offer the following employee benefits and perquisites to our named executive officers to remain competitive in the marketplace:

•: Healthcare contribution—We contribute to each named executive officer's health, vision and dental insurance premiums.
•: Moving expenses—We reimburse our named executive officers for normal moving expenses associated with employment.
•: Life and disability insurance premiums—We contribute to each named executive officer's life insurance premiums, short-term and long-term disability premiums and accidental death & dismemberment premiums.
•: 401(k) Plan and Matching Contributions—Each of our named executive officers is eligible to participate in the 401(k) plan which allows for a 100% company match on employee contributions up to 6%. The plan provides for immediate participation upon hire and includes a five year vesting period.

For a further description of these benefits, please refer to the Summary Compensation Table set forth herein.

In the future, the compensation committee, in its discretion, may revise, amend or add to the officers' executive benefits and perquisites if it deems advisable. We believe these benefits and perquisites are currently at competitive levels for comparable companies.

Severance and Change in Control Benefits

The employment agreements with our named executive officers as well as our incentive plans will require us to provide compensation or other benefits to our named executive officers in connection with certain events related to a termination of employment or change in control. For a description of the terms of these arrangements see "Termination of Employment and Change-in-Control Arrangements."

We have established these arrangements because we believe providing executive officers compensation and benefits arrangements upon a change in control is necessary in order for us to be competitive with compensation packages of other similarly situated companies and assists us in recruiting and retaining talented executives. In addition, formalizing our termination and change in control benefits provides us with certainty in terms of our obligations to an eligible executive in the event that our relationship with any such executive is terminated.

Impact of Tax Treatment on Compensation

In general, a federal income tax deduction is not allowed for annual compensation in excess of $1,000,000 paid to the chief executive officer or any of the four other most highly compensated officers of a public company. However, qualifying "performance-based" compensation is not counted against this limit. It is anticipated that stock options and SARs awarded under our long-term incentive plan will be deemed to be "performance-based" compensation that is not subject to the deduction limit. In addition, certain other awards that may be conditioned by our compensation committee on the attainment of prescribed performance goals may also qualify as "performance-based" compensation that is not subject to the deduction limit. To satisfy the requirements that apply to "performance-based" compensation, the performance measures must be approved by our stockholders, subject to transition relief that would apply generally to grants made before the 2011 annual stockholder meeting. It is expected that the performance measures to be used under a plan will be submitted for stockholder approval at the 2011 annual stockholder meeting (if not sooner).

While we seek to take advantage of favorable tax treatment for executive compensation where appropriate, the primary drivers for determining the amount and form of executive compensation must be the retention and motivation of superior executive talent rather than tax-based considerations.

Summary Compensation Table

The following table sets forth the compensation for our chief executive officer, our chief financial officer, our former chief financial officer and our two other most highly compensated executive officers for the fiscal year ended December 31, 2006. We have no other executive officers. We refer to these officers collectively herein as our named executive officers.

(2): Vested performance units can be redeemed for cash or in the form of the same equity instruments received due to a change in control or an initial public offering, at the discretion of the board of directors. If there is no such triggering event, a participant would receive no amounts payable on the performance units. The target and maximum amounts assume a one-for-one redemption upon a triggering event.
(3): There is no per unit exercise price for the performance units under the performance unit plans.
(4): Performance units are only valued at the time of a change in control or other triggering event, including an initial public offering. The performance units do not have any value until such a triggering event occurs. Accordingly, no equity was recorded for the performance units at the time of their grant.

Director Compensation

None of the members of our predecessor Monosol Rx LLC board of directors received any compensation from us during 2006 or any preceding periods.

Upon the closing of this offering, we intend to provide cash compensation and stock options to non-employee members of our board of directors for serving on our board of directors. We will pay each of our non-employee directors $25,000 per year for serving on our board of directors. In addition to compensation for board services, we will pay the members of our committees $10,000 per year to each member of our audit committee and $5,000 per year to each member of our compensation committee and governance and nominating committee. In addition to any payments for being a member of the various committees of our board of directors, we will also pay the chair of the audit committee $10,000 and the chairs of each of the compensation committee and the governance and nominating committee $5,000. We will also pay each member of the board of directors $1,500 per meeting of the board of directors. Members of our board of directors are reimbursed for some expenses in connection with attendance of board and committee meetings.

We anticipate that, before the completion of the initial public offering, our board of directors will adopt and our stockholders will approve a new long-term incentive plan. Upon the completion of this offering, it is anticipated that each of our directors will receive an option to acquire 15,000 shares of our common stock. We expect that this initial grant will vest quarterly over three years. On the date a new director is first elected or appointed to the board of directors, we intend that he or she will automatically be granted an option to acquire 15,000 shares of our common stock on the date of the grant. In addition, upon election of directors each year, we intend that each director will receive an automatic grant of options to acquire 5,000 shares of common stock on a fully diluted basis on the date of the grant. We expect that these options will also vest quarterly over three years.

Termination of Employment and Change-in-Control Arrangements

The types of arrangements that would trigger payments to our named executive officers upon a change in control of the company include employment agreements, our stock incentive plan and our performance unit plans. We have established these arrangements because we believe providing executive officers compensation and benefits arrangements upon a change in control is necessary in order for us to be competitive with compensation packages of other similarly-situated companies and assists us in recruiting and retaining talented executives.

•: reimbursement for his cost of purchasing medical benefits for himself under COBRA (provided COBRA is available and elected) during the "severance period" (as defined in the employment agreement) or until such time as Mr. Fischer is eligible to receive medical benefits from another employer, whichever is shorter.

Performance Unit Plans

Within the context of the performance unit plans, a change in control is generally defined as an event or series of events (such as a merger, acquisition or reorganization) that result in our beneficial owners immediately preceding the change in control owning less than 20% of the company following the change of control event or an initial public offering as contemplated herein.

Upon a change in control each participant's unvested units immediately vest and we are obligated to make a payment, either in cash or in the same consideration received by us upon the change in control.

Each participant's distribution under the plan would be calculated in the following manner as defined in the plan:

Number of participant's vested
performance units

Number of outstanding
performance units

× (fair market value minus base value) = total payment

Fair market value is defined as the fair market of the company prior to the change in control. Base value is the base value assigned to each individual grant made to a participant.

Long-Term Incentive Plan

We anticipate that, before the completion of the initial public offering, our board of directors will adopt and our stockholders will approve a new long-term incentive plan. In order to protect the rights of participants, we expect that our stock incentive plan will provide that, in the event of a change in control, as defined in the plan, outstanding awards made under the plan will either (1) be converted into equivalent awards with respect to shares of stock of the acquiring or successor company, or (2) be fully vested and settled in cash or shares. In general, we expect that if an award is converted into an equivalent award, the award will continue to be subject to the vesting and other terms and conditions applicable to the original award; however, vesting may accelerate in the event of an involuntary termination of employment within two years after the date of the change in control. Our board of directors will be responsible for determining the disposition of awards in the event of a change in control. No awards have been made under the plan at this time.

Potential Payments Upon Termination Without a Change in Control

The following table provides quantitative disclosure of the estimated payments and benefits that would be provided to our named executive officers assuming that each named executive officer's employment with us was terminated on December 29, 2006, the last business day of our fiscal 2006, and was not in connection with an event which constituted a "Change in Control" under any agreement or plan described above. We have also assumed that the base salary earned by each named executive officer for his services to us through December 29, 2006 was fully paid.

(1): Under the terms of our performance unit Plan B, our advisory board may, in its sole discretion, elect to provide a participant in the plan with a cash payment in an amount equal to the number

of each such participant's vested performance units divided by the outstanding unit amount, multiplied by the fair market value minus the base value of the award. We may elect to make this cash payment within 12 months of an officer's termination. Historically, we have never exercised this discretion and do not intend to do so in the future. We have assumed a fair market value of $100,000,000 as of December 29, 2006, which is based upon the most recent valuation by our board of advisors as of September 18, 2006, in anticipation of our private placement of preferred members interests. It is possible that our value could have been higher at December 29, 2006, if appraised at that time.

•: Mr. Schobel: 459,830 vested performance units granted at a base value of $20,000,000
•: Mr. Kendall: 507,068 vested performance units granted at a base value of $87,500,000
•: Mr. Fuisz: 1,786,908 vested performance units granted at a base value of $12,500,000 (granted under Plan A); 86,962 vested performance units granted at a base value of $17,857,143; and 30,424 vested performance units granted at a base value of $20,000,000. We have assumed that, if the advisory board were to exercise its discretion as to Mr. Fuisz's performance units that were granted under Plan B, it would exercise similar discretion with respect to the 1,786,908 performance units granted under Plan A.
•: Dr. Sanghvi: 173,925 vested performance units granted at a base value of $13,750,000; and 4,057 vested performance units granted at a base value of $20,000,000
•: Mr. Fischer: 43,608 vested performance units granted at a base value of $20,000,000.

(2): If we elect not to exercise our discretion with respect to a cash payment, Mr. Schobel's employment agreement provides for the pro rata vesting of Mr. Schobel's performance units up to the date of termination, and at his option, not be subject to repurchase. This consists of the vesting of 459,830 performance units. The performance units do not have any value until there is a triggering event, such as a termination or change in control, including an initial public offering. Accordingly, there is no value linked to the vesting of the performance units.
(3): Mr. Kendall is entitled to an amount equal to the unvested portion of his 401(k) account, which as of December 29, 2006 was $0.
(4): Amounts are determined in accordance with the respective employment agreements that were in effect as of December 29, 2006 for Messrs. Fuisz and Fischer.
(5): On May 12, 2007, we entered into an amended and restated employment agreement with Mr. Fuisz. If Mr. Fuisz's amended and restated employment agreement is terminated for a reason other than his voluntary resignation or his termination for "cause" (as defined in his amended and restated employment agreement), then the vesting schedule of his remaining units will not be affected and will bridge any such break in service. We have entered into a letter agreement with Mr. Fuisz which provides for similar continued vesting in the event his employment with, or his engagement as a consultant by, us is terminated for a reason other than his voluntary resignation or his termination for "cause" (as defined in Plan A).

Potential Payments Upon a Change in Control Without Termination

The following table provides quantitative disclosure of the estimated payments and benefits that would be provided to our named executive officers assuming an event which constituted a "change in control" under any agreement or plan described above on December 29, 2006, the last business day of our fiscal 2006, in connection with which none of the named executive officers' employment with us was terminated.

Upon a change in control, all performance units held by each of our named executive officers will automatically vest. The vested performance units may be redeemed for cash or in the form of the same equity instruments received due to a change in control or an initial public offering, at our discretion. The value of the performance units is calculated as follows

Number of participant's vested
performance units

Number of outstanding
performance units

× (fair market value minus base value)

Fair market value is defined as the fair market of the company at the change in control. Base value is the base value assigned to each individual grant of performance units made to a participant. We have assumed a fair market value of $100,000,000 as of December 29, 2006, which is based upon the most recent valuation by our board of advisors as of September 18, 2006, in anticipation of our private placement of preferred members interests. It is possible that our value could have been higher at December 29, 2006, if appraised at that time. In accordance with the foregoing assumptions, the following table provides the potential realizable value of the performance units held by our named executive officers.

Limitations On Liability And Indemnification Of Directors And Officers

We have adopted provisions in our certificate of incorporation that limit or eliminate the personal liability of its directors to the maximum extent permitted by the Delaware General Corporation Law, or DGCL. The DGCL expressly permits a corporation to provide that its directors will not be liable for monetary damages for a breach of their fiduciary duties as directors, except for liability:

•: for or any breach of the director's duty of loyalty to us or our stockholders;
•: for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
•: for any unlawful payments of dividends or unlawful stock purchases or redemptions; or
•: for any transaction from which the director derived an improper personal benefit.

These limitations of liability do not generally affect the availability of equitable remedies such as injunctive relief or rescission. Our certificate of incorporation and bylaws also authorize us to indemnify our officers, directors, employees and other agents to the fullest extent permitted under the DGCL and we may advance expenses to our directors, officers, employees and other agents in connection with a legal proceeding, subject to limited exceptions. In addition, we maintain directors' and officers' liability insurance for our officers and directors.

As permitted by the DGCL, our certificate of incorporation and bylaws provide that:

•: we must indemnify our board members and officers to the fullest extent permitted by the DGCL and advance expenses to our board members and officers in connection with a legal proceeding, subject to limited exceptions; and
•: we may purchase and maintain insurance on behalf of our current or former board members, officers, employees or agents against any liability asserted against them and incurred by them in any such capacity, or arising out of their status as such.

In March 2007, we entered into separate indemnification agreements with each of our directors. Prior to the completion of this offering, we will enter into separate indemnification agreements with each of our board members and certain of our officers that will require us to indemnify them to the fullest extent permitted by the DGCL. These indemnification agreements will also require us to advance any expenses incurred by the board members and certain officers as a result of any proceeding against them as to which they could be indemnified.

The limited liability and indemnification provisions in our certificate of incorporation and bylaws and in any indemnification agreements we enter into may discourage stockholders from bringing a lawsuit against our board members for breach of their fiduciary duties and may reduce the likelihood of derivative litigation against our board members and officers, even though a derivative action, if successful, may otherwise benefit us and our stockholders. A stockholder's investment in us may be adversely affected to the extent we pay the costs of settlement or damage awards against our directors and officers under these indemnification provisions.

At present, there is no pending litigation or proceeding involving any of our directors, officers, employees or agents in which indemnification by us is sought, nor are we aware of any threatened litigation or proceeding that may result in a claim for indemnification.

PRINCIPAL STOCKHOLDERS

The following table sets forth information regarding the beneficial ownership of the common stock of MonoSol Rx, Inc. before and after the completion of this offering (on a pro forma basis, after giving effect to the conversion of the membership interest for common stock as described under "Corporate Formation Transactions") and shows the number and percentage owned by:

•: each of our directors;
•: each of our named executive officers;
•: all of our directors and executive officers as a group; and
•: each person or group of affiliated persons whom we know to beneficially own more than 5% of our common stock.

Beneficial ownership and percentage ownership are determined in accordance with the rules of the SEC. This information does not necessarily indicate beneficial ownership for any other purpose. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of common stock underlying options or warrants held by that person that are currently exercisable or will become exercisable within 60 days are deemed outstanding and are included in the number of shares beneficially owned, while the shares are not deemed outstanding for purposes of computing percentage ownership of any other person. There are currently no options or warrants outstanding. To our knowledge, except as indicated in the footnotes to this table and subject to community property laws where applicable, the persons named in the table have sole voting and investment power with respect to all shares of our common stock shown as beneficially owned by them.

The address for those individuals for which an address is not otherwise indicated is: c/o MonoSol Rx, Inc., 30 Technology Drive, Warren, New Jersey 07059.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Corporate Transaction

In accordance with the agreement and plan of merger, after the merger our equity will continue to be owned by the same entities in the same proportions as before the merger. After completion of this offering, our existing equity owners, which include the direct and indirect holders of membership interests in Monosol Rx LLC will own shares of our common stock representing approximately % of the voting power of our outstanding capital stock. See "Principal Stockholders" for more information regarding the ownership of our common stock.

Unsecured Note—Dr. Richard Fuisz

In conjunction with Monosol Rx LLC's formation in January 2004 we assumed an unsecured note payable to Dr. Richard Fuisz with a principal amount of approximately $904,000. At December 31, 2006 the note was repaid and $347,650 was outstanding at December 31, 2005. Interest expense on the note was $21,890, $38,386 and $41,324 for the years ended December 31, 2006, 2005 and 2004, respectively.

Monosol, LLC Asset Purchase

In December 2006, we sold an asset consisting of a small film casting machine to Monosol, LLC for $200,000. The asset was part of the original capital contribution to Monosol Rx LLC by Monosol, LLC made in 2004 at the time the company was formed. The machine was found to be unsuitable for pharmaceutical applications and as such not used in our operations. Prior to the transaction, in order to determine an appropriate sales price we obtained independent estimates from dealers in the secondary market. The sales price was in excess of the estimates obtained. In addition, during 2006 we received $54,000 in rent from Monosol, LLC for use of the asset.

Melton Road Lease Amendment and Guarantee

In September 2006, Monosol Rx LLC, with the landlord's agreement and acceptance, assigned to us all rights and obligations of the existing lease. As part of the agreement Monosol, LLC agreed to guarantee lease payments in an aggregate amount of $218,423 through March 2008. In January 2007, the landlord released Monosol, LLC from its guarantee in consideration for us providing a security deposit in the amount of three months rent and amending the date we need to provide notice to the landlord that we do not intend to renew our lease from six months to nine months prior to the end of the current lease term.

Monosol, LLC Cost Allocation

The statements of operations include certain shared costs allocated to us by Monosol, LLC. Charges for rent, insurance, employee fringe benefits, and other overhead costs are based on the ratio of payroll expense of our employees to aggregate payroll expense for Monosol, LLC employees. In the opinion of management, the costs charged have been allocated on a basis that is believed to be reasonable within the structure of Monosol, LLC. However, the costs charged are not necessarily indicative of the level of expenses that may have been incurred if we and the Predecessor had operated as a stand alone entity. The total amount of costs allocated to us was $250,000, $696,000 and $727,000 for 2006, 2005 and 2004, respectively. As of October 2006 the cost allocation arrangement with Monosol, LLC was terminated.

Consulting Agreements

In conjunction with our purchase of all of the assets of Kosmos Pharma Limited, Dr. Richard Fuisz and his son, Mr. Joseph Fuisz, Esq., significant shareholders in Kosmos Pharma Limited, entered into consulting agreements with the Company. These consulting agreements were each for a three year term and provided for a monthly and annual fee of $13,333 and $160,000, respectively, plus the reimbursement of certain expenses. Including reimbursed fees, we paid Dr. Fuisz $163,301, $179,806 and $148,925 for 2006, 2005, and 2004 respectively, and Joseph Fuisz $224,117, $281,010 and $197,319 for 2006, 2005, and 2004, respectively, under the agreements. The contract between us and Mr. Joseph Fuisz, Esq. was terminated and Mr. Fuisz became our employee in September 2006.

In September 2006, the consulting agreement between us and Dr. Fuisz was extended through September 2009 with substantially the same terms. We have agreed to provide Dr. Fuisz with a one-time fee of $100,000 under his consulting agreement within 15 days after the date that the registration statement becomes effective. We will have no obligation to pay this fee in the event that the registration statement becomes effective after December 31, 2007.

We agreed to transfer the assets and properties relating to certain technology and intellectual property unrelated to thin film to a new Delaware limited liability company, 55% of the interests of which will be owned by Dr. Fuisz and 45% of the interests of which will be owned by our members as of the date of such transfer. We have also agreed to release Dr. Fuisz from all claims that we may have now or in the future against him, with the exception of claims arising under certain agreements between us and Dr. Fuisz or his affiliates. We have also agreed to indemnify Dr. Fuisz to the same extent we have agreed to indemnify our officers and directors.

We also are a guarantor through May 2007 of a lease for office space in Washington, D.C. that is used by Dr. Fuisz and Joseph Fuisz, Esq. The aggregate remaining lease payments through May 2007 are $12,153. We made payments to Dr. Fuisz in connection with the lease of $28,386, $29,893 and $41,133 for 2006, 2005 and 2004 respectively. We have agreed to extend this lease on a month to month basis.

DESCRIPTION OF CAPITAL STOCK

General

Upon completion of this offering, the total amount of our authorized capital stock will consist of 100,000,000 shares of common stock, par value $.01 per share, and 20,000,000 shares of preferred stock, par value $.01 per share. As of April 15, 2007, there were no shares of common stock outstanding and no shares of preferred stock outstanding. As of April 15, 2007, we had no record holders of our common stock. In addition, as of , 2007 shares of our common stock were reserved for grants under our stock incentive plan, and options to purchase a total of zero shares of our common stock were outstanding. As of April 1, 2007, pursuant to our predecessor's performance unit plans there were 22,796,404 units outstanding which will be converted to shares of our common stock.

Immediately after this offering, there will be shares of our common stock and no shares of preferred stock outstanding.

The following description of our capital stock does not purport to be complete and is subject to, and is qualified by, our certificate of incorporation and bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part, and by the applicable provisions of Delaware law.

Common Stock

Voting

The holders of our common stock are entitled to one vote for each share held of record on each matter submitted to a vote of stockholders, including the election of directors, and do not have any right to cumulative votes in the election of directors.

Dividends

Subject to the rights and preferences of the holders of any series of preferred stock which may at the time be outstanding, holders of our common stock are entitled to such dividends as our board of directors may declare from time to time out of legally available funds. Dividends on the common stock are not cumulative.

Liquidation rights

In the event of any liquidation, dissolution or winding-up of our affairs, after payment of all of its debts and liabilities, and subject to the rights and preferences of the holders of any outstanding shares of any series of its preferred stock, the holders of our common stock will be entitled to receive their pro rata distribution of any of our remaining assets.

Other matters

Holders of our common stock have no conversion, preemptive or other subscription rights and there are no redemption rights or sinking fund provisions with respect to the common stock. The shares of our common stock to be sold in this offering when issued and paid for will be validly issued, fully paid and non-assessable.

Preferred Stock

We are authorized to issue up to 20,000,000 shares of preferred stock. Our certificate of incorporation authorizes our board, from time to time, without any further stockholder action or approval: to issue these shares in one or more classes or series; to establish from time to time the number of shares to be included in each class or series; and to fix the designation, powers, preferences,

and rights of the shares of each wholly unissued class or series and any of its qualifications, limitations or restrictions. In some circumstances, the issuance of shares of preferred stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management. Our board may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. We currently have no plans to issue any shares of preferred stock.

Certain Provisions of Our Certificate of Incorporation, Bylaws and Delaware Law

Provisions of our certificate of incorporation, bylaws and Delaware law, which are summarized below, may be deemed to have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a stockholder may consider in such stockholder's best interest, including those attempts that may result in a premium over the market price for our common stock. These provisions include restrictions on stockholder's ability to take action by written consents, elimination of the ability of stockholders to call special meetings, advance notice procedures for stockholder proposals and director nominations, and certain Delaware law provisions.

Number of Directors; Removal for Cause; Filling Vacancies

Our certificate of incorporation provides that our board of directors will consist of one or more directors, the exact number of which will be fixed from time to time by the board. Our board of directors will consist of six directors.

Our bylaws provide that any newly created directorships on our board, or any other vacancy on the board, may be filled by a majority of the board then in office, even if a quorum is not present, or by a plurality of votes cast at a meeting of the stockholders. Any director elected in accordance with the preceding sentence will hold office for the remainder of the full term of office of the director whom he or she replaced or until such director's successor shall have been elected and qualified.

Special Meetings of Stockholders

Our bylaws deny stockholders the right to call a special meeting of stockholders. Our bylaws provide that a special meeting of stockholders may be called only by our board.

Stockholder Action by Written Consent

Our certificate of incorporation and bylaws deny stockholders the ability to act by written consent without a meeting, unless the holders of 66²/3% of our issued and outstanding stock act by such a written consent. All other stockholder action must take place at a meeting of stockholders.

Stockholder Proposals

At an annual meeting of stockholders, only business that is properly brought before the meeting will be conducted or considered. To be properly brought before an annual meeting of stockholders, business must be specified in the notice of the meeting (or any supplement to that notice), brought before the meeting by or at the direction of the board (or any duly authorized committee of the board) or properly brought before the meeting by a stockholder. For business to be properly brought before an annual meeting by a stockholder, the stockholder must have given timely written notice of the business in proper written form to our secretary.

To be timely, a stockholder's notice must be delivered to or mailed and received at our principal executive offices not less than 60 days nor more than 180 days prior to the anniversary date of the last annual meeting; provided, however, that in the event that the annual meeting is called for a date that is

not within 45 days before or after the anniversary date, notice by the stockholder must be received not later than the close of business on the 10th day following the day on which notice of the date of the annual meeting was mailed or public disclosure of the date of the annual meeting was made, whichever first occurs.

To be in proper written form, a stockholder's notice to the secretary must set forth as to each matter the stockholder proposes to bring before the annual meeting:

Similarly, at a special meeting of stockholders, only such business as is properly brought before the meeting will be conducted or considered. To be properly brought before a special meeting, business must be specified in the notice of the meeting (or any supplement to that notice).

Nomination of Candidates for Election to Our Board

Under our bylaws, only persons who are properly nominated will be eligible for election to be members of our board. To be properly nominated, a director candidate must be nominated at an annual meeting of the stockholders or any special meeting called for the purpose of electing directors by or at the direction of our board (or any duly authorized committee of the board) or properly nominated by a stockholder. To properly nominate a director, a stockholder must:

•: be entitled to vote at the meeting; and
•: have given timely written notice in proper written form to our secretary.

To be timely, a stockholder's notice must be delivered to or mailed and received at our executive offices:

any other information relating to the person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to Section 14 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations promulgated thereunder; and

•: as to the stockholder giving the notice:

•

the name and record address of such stockholder;

•

the class or series and number of shares of our capital stock that are owned beneficially or of record by such stockholder;

a representation that the stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice.

Amendment of Certificate of Incorporation and Bylaws

Our certificate of incorporation can only be amended by the approval of a majority of the stockholders. Our bylaws provide that the board of directors or the stockholders have the right to alter, amend or repeal the bylaws. In addition, our certificate of incorporation grants our board of directors the authority to amend and repeal our bylaws without a stockholder vote in any manner not inconsistent with the laws of the State of Delaware or our certificate of incorporation.

Delaware Law

We will be subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, those provisions prohibit a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

•: prior to that date, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
•: upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding those shares owned by directors and officers and shares issued under employee stock plans under which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
•: on or after the date the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

Section 203 defines "business combination" to include the following:

•: any merger or consolidation involving the corporation and the interested stockholder;
•: any sale, lease, exchange, mortgage, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

•: subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
•: any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or
•: the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling, controlled by, or under common control with the entity or person.

MATERIAL U.S. FEDERAL TAX CONSIDERATIONS
FOR NON-U.S. HOLDERS OF OUR COMMON STOCK

The following is a general discussion of the material U.S. federal income and estate tax considerations applicable to non-U.S. holders with respect to their ownership and disposition of shares of our common stock. This discussion is for general information only and is not tax advice. Accordingly, all prospective non-U.S. holders of our common stock should consult their own tax advisors with respect to the United States federal, state, local and non-U.S. tax consequences of the acquisition, ownership and disposition of our common stock. For purposes of this discussion, a "non-U.S. holder" means a beneficial owner of our common stock who is not for U.S. federal income tax purposes:

•: an individual citizen or resident of the United States;
•: a corporation, partnership, or any other organization taxable for U.S. federal income tax purposes as a corporation or partnership created or organized in the United States or under the laws of the United States, any state thereof, or the District of Columbia;
•: an estate the income of which is included in gross income for U.S. federal income tax purposes regardless of its source; or
•: a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) a valid election is in place to treat the trust as a U.S. person.

If a partnership holds our common stock, the tax treatment of its partners generally will depend on the status of the partner and upon the activities of the partnership. Accordingly, partnerships that are prospective investors in our common stock, and partners in such partnerships, should consult their tax advisors.

This discussion is based on current provisions of the United States Internal Revenue Code of 1986, as amended, existing and proposed United States Treasury Regulations promulgated thereunder, current administrative rulings and judicial decisions, all of which are in effect as of the date of this prospectus and all of which are subject to change or to differing interpretation. Any change, which may or may not be retroactive, could alter the tax consequences to non-U.S. holders described in this prospectus.

This discussion does not address all aspects of U.S. federal income and estate taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder's circumstances nor does it address any aspects of U.S. state, local or non-U.S. taxes. This discussion does not address the consequences to non-U.S. holders subject to special rules, including, U.S. expatriates; "controlled foreign corporations" or "passive foreign investment companies;" or non-U.S. holders that own more than 5% of our common stock.

There can be no assurance that the Internal Revenue Service, or IRS, will not challenge one of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, an opinion of counsel with respect to the U.S. federal income or estate tax consequences to a non-U.S. holder of the acquisition, ownership, or disposition of our common stock. We urge prospective investors to consult with their own tax advisors regarding the U.S. federal, estate, state and local, and non-U.S. income and other tax considerations of acquiring, holding and disposing of shares of our common stock.

Distributions with respect to Our Common Stock

We have not declared or paid distributions on our common stock since our inception and do not intend to pay any distributions on our common stock in the foreseeable future. In the event we do pay

100

distributions on our common stock, however, these distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated first as a tax-free return of the non-U.S. holder's investment, up to such holder's tax basis in the common stock and then any remaining excess will be treated as gain from the sale of common stock, subject to the tax treatment described below in "Gain on Sale or Other Disposition of Our Common Stock."

Dividends paid to a non-U.S. holder generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be provided by an applicable income tax treaty. In order to obtain a reduced rate of withholding, a non-U.S. holder will be required to provide an Internal Revenue Service Form W8-BEN certifying its entitlement to a reduced rate of withholding under a treaty. If we determine, at a time reasonably close to the date of payment of a distribution on our common stock, that the distribution will not qualify as a dividend because we do not anticipate having current or accumulated earnings and profits, we intend not to withhold any U.S. federal income tax on the distribution as permitted by United States Treasury Regulations.

Dividends paid to a non-U.S. holder that are treated as "effectively connected" with a trade or business conducted by such non-U.S. holder within the United States (and, if an applicable income tax treaty so provides, are also attributable to a permanent establishment of such non-U.S. holder), known as "United States trade or business income," are generally exempt from the 30% withholding tax if the non-U.S. holder provides a properly completed Internal Revenue Service Form W-8ECI and satisfies certain other requirements. However, such United States trade or business income, net of specified deductions and credits, is taxed at the same graduated U.S. federal income tax rates applicable to United States persons. Additionally, United States trade or business income received by a non-U.S. holder that is a corporation may also be subject to an additional "branch profits tax" at a 30% rate or such lower rate specified by an applicable income tax treaty.

A non-U.S. holder that is eligible for a reduced rate of United States withholding or other withholding exclusion under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for refund or credit with the IRS.

Gain on Sale or Other Disposition of Our Common Stock

In general, a non-U.S. holder will not be subject to any U.S. federal income tax or withholding tax on any gain recognized upon such holder's sale or other disposition of shares of our common stock unless:

•: the gain is United States trade or business income, in which case such holder will be subject to tax on the net gain derived from the sale or disposition at the graduated United States federal income tax rates applicable to United States persons; and, if the non-U.S. holder is a corporation, such holder may also be subject to the branch profits tax, both as described above in "Distributions with respect to Our Common Stock;"
•: the non-U.S. holder is an individual who is present in the United States for 183 days or more during the taxable year of the disposition and meets certain other requirements in which case the holder will be subject to a flat 30% tax on the amount by which the gain derived from the sale, and certain other United States source capital gains recognized during such year exceed certain United States source capital losses recognized during such year; or
•: certain rules relating to "United States real property holding corporation" status apply to such sale or other disposition. Under such rules, gain recognized on a sale or other disposition of our common stock may be subject to U.S. federal income tax (and, in certain circumstances, withholding tax) if (1) our common stock is not regularly traded on an established securities

101

market prior to the beginning of the calendar year in which the sale or disposition occurs and (2) we are, or have been, a United States real property holding corporation during the shorter of the five-year period ending on the date of such sale or other disposition or the period that the non-U.S. holder held our common stock. Generally, we would be considered a United States real property holding corporation if the fair market value of our "United States real property interests" were to equal or exceed 50% of the aggregate fair market value of our worldwide real property interests and our other assets used or held for use in our trade or business. Although there can be no assurance, we do not believe that we are, or have been, a United States real property holding corporation, or that we are likely to become one in the foreseeable future.

United States Federal Estate Tax

Shares of our common stock that are owned or treated as owned by an individual non-U.S. holder at the time of such non-U.S. holder's death will be included in such individual's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax or other treaty provides otherwise, and therefore may be subject to U.S. federal estate tax.

Backup Withholding, Information Reporting and Other Reporting Requirements

We must report to the IRS and to each non-U.S. holder the gross amount of any dividends paid to such holder with respect to our common stock, and the tax withheld, if any, upon the payment of such dividends. In addition, information reporting and backup withholding (at a rate of 28% through 2010, and 31% thereafter) generally will apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the United States office of a broker unless the holder certifies its status as a non-U.S. holder and satisfies certain other qualifications, or otherwise establishes an exemption. Generally, such information reporting and backup withholding will not apply to a payment of disposition proceeds if the transaction is effected outside the United States through a non-U.S. office of a non-U.S. broker. However, for information reporting purposes, certain brokers with substantial United States ownership or operations are treated in a manner similar to United States brokers. Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which a non-U.S. holder resides or is incorporated.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can be refunded or credited against the non-U.S. holder's U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS.

102

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there was no public market for our common stock. Future sales of substantial amounts of our common stock in the public market, or the perception that these sales could occur, could adversely affect the price of our common stock.

Upon completion of this offering, we will have approximately shares of our common stock outstanding (approximately shares if the underwriters exercise their overallotment option in full). Of those shares, the shares of common stock sold in this offering ( shares if the underwriters exercise their overallotment option in full) will be freely transferable without restriction, unless purchased by our affiliates. The remaining approximately shares of common stock to be outstanding immediately following the completion of this offering, which are "restricted securities" under Rule 144 of the Securities Act of 1933, as amended, or Rule 144, as well as any other shares held by our affiliates, may not be resold except pursuant to an effective registration statement or an applicable exemption from registration, including an exemption under Rule 144.

Lock-Up Agreements

The holders of approximately shares of outstanding common stock as of the closing of this offering, including all of our officers and directors, have entered into lock-up agreements under which they have generally agreed, subject to certain exceptions, not to offer or sell any shares of common stock or securities convertible into or exchangeable or exercisable for shares of common stock for a period of at least 180 days from the date of this prospectus without the prior written consent of Cowen and Company, LLC. See "Underwriting—No sales of similar securities."

Rule 144

In general, under Rule 144, an affiliate of ours who beneficially owns shares of our common stock that are not restricted securities, or a person who beneficially owns for more than one year shares of our common stock that are restricted securities, may generally sell, within any three-month period, a number of shares that does not exceed the greater of:

•: 1% of the number of shares of our common stock then outstanding, which will equal approximately shares immediately after this offering; and
•: the average weekly trading volume of our common stock on the Nasdaq Global Market during the four preceding calendar weeks.

Sales under Rule 144 are also subject to requirements with respect to manner of sale, notice and the availability of current public information about us. Generally, a person who was not our affiliate at any time during the three months before the sale, and who has beneficially owned shares of our common stock that are restricted securities for at least two years, may sell those shares without regard to the volume limitations, manner of sale provisions, notice requirements or the requirements with respect to availability of current public information about us.

Rule 144 does not supersede the contractual obligations of our security holders set forth in the lock-up agreements described above.

Rule 701

Generally, an employee, officer, director or consultant who purchased shares of our common stock before the effective date of the registration statement of which this prospectus is a part, or who holds options as of that date, under a written compensatory plan or contract, may rely on the resale provisions of Rule 701 under the Securities Act of 1933, as amended. Under Rule 701, these persons who are not our affiliates may generally sell their eligible securities, commencing 90 days after the

103

effective date of the registration statement of which this prospectus is a part, without having to comply with the public information, holding period, volume limitation or notice provisions of Rule 144. These persons who are our affiliates may generally sell their eligible securities under Rule 701, commencing 90 days after the effective date of the registration statement of which this prospectus is a part, without having to comply with Rule 144's one-year holding period restriction.

Neither Rule 144 nor Rule 701 supersedes the contractual obligations of our security holders set forth in the lock-up agreements described above.

Sale of Restricted Shares

The shares of our common stock that were outstanding will become eligible for sale, pursuant to Rule 144 or Rule 701, without registration approximately as follows:

•: approximately shares of common stock will be immediately eligible for sale in the public market without restriction;
•: approximately shares of common stock will be eligible for sale in the public market under Rule 144 or Rule 701, beginning 180 days after the effective date of the registration statement of which this prospectus is a part, subject to the volume, manner of sale and other limitations under those rules; and

The above does not take into consideration the effect of the lock-up agreements described above.

2007 Stock Incentive Plan

We intend to file a registration statement on Form S-8 under the Securities Act to register the shares of common stock available for issuance under our 2007 Stock Incentive Plan. Subject to the lock-up agreements, shares issued under these plans after the effective date of such registration statement will be available for sale in the open market and, for our affiliates, subject to the conditions and restrictions of Rule 144. As of April 15, 2007, options to purchase a total of zero shares of common stock were outstanding under our 2007 Stock Incentive Plan and shares of our common stock were available for future grant under the 2007 Stock Incentive Plan.

104

UNDERWRITING

We and the underwriters for the offering named below have entered into an underwriting agreement with respect to the common stock being offered. Subject to the terms and conditions of the underwriting agreement, each underwriter has severally agreed to purchase from us the number of shares of our common stock set forth opposite its name below. Cowen and Company, LLC is the representative of the underwriters.

Underwriters			Number of Shares
Cowen and Company, LLC
CIBC World Markets Corp.
Susquehanna Financial Group, LLLP




	Total

The obligations of the underwriters may be terminated upon the occurrence of the events specified in the underwriting agreement. The underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased, other than those shares covered by the overallotment option described below. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against specified liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments the underwriters may be required to make in respect thereof.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Overallotment Option to Purchase Additional Shares. We have granted to the underwriters an option to purchase up to additional shares of common stock at the public offering price, less the underwriting discount. This option is exercisable for a period of 30 days. The underwriters may exercise this option solely for the purpose of covering overallotments, if any, made in connection with the sale of common stock offered hereby. To the extent that the underwriters exercise this option, the underwriters will purchase additional shares from us in approximately the same proportion as shown in the table above.

Discounts and Commissions. The following table shows the public offering price, underwriting discount and proceeds, before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional shares.

105

We estimate that the total expenses of the offering, excluding underwriting discount, will be approximately $ and are payable by us.

Proceeds, before expenses, to us

The underwriters propose to offer the shares of common stock to the public at the public offering price set forth on the cover of this prospectus. The underwriters may offer the shares of common stock to securities dealers at the public offering price less a concession not in excess of $ per share. The underwriters may allow, and the dealers may reallow, a discount not in excess of $ per share to other dealers. If all of the shares are not sold at the public offering price, the underwriters may change the offering price and other selling terms.

Discretionary Accounts. The underwriters do not intend to confirm sales of the shares to any accounts over which they have discretionary authority.

Market Information. Prior to this offering, there has been no public market for shares of our common stock. The initial public offering price will be determined by negotiations between us and the representative of the underwriters. In addition to prevailing market conditions, the factors to be considered in these negotiations will include:

•: the history of, and prospects for, our company and the industry in which we compete;
•: our past and present financial information;
•: an assessment of our management; its past and present operations, and the prospects for, and timing of, our future revenues;
•: the present state of our development; and
•: the above factors in relation to market values and various valuation measures of other companies engaged in activities similar to ours.

An active trading market for the shares may not develop. It is also possible that after the offering the shares will not trade in the public market at or above the initial public offering price.

We have applied for the quotation of our common stock on the Nasdaq Global Market under the symbol "MSRX."

Stabilization. In connection with this offering, the underwriters may engage in stabilizing transactions, overallotment transactions, syndicate short covering transactions, penalty bids and purchases to cover positions created by short sales.

•: Stabilizing transactions permit bids to purchase shares of common stock so long as the stabilizing bids do not exceed a specified maximum, and are engaged in for the purpose of preventing or retarding a decline in the market price of the common stock while the offering is in progress.
•: Overallotment transactions involve sales by the underwriters of shares of common stock in excess of the number of shares the underwriters are obligated to purchase. This creates a syndicate short position which may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the overallotment option. In a naked short position, the number of shares involved is greater than the number of shares in the

106

overallotment option. The underwriters may close out any short position by exercising their overallotment option and/or purchasing shares in the open market.

•: Syndicate covering transactions involve purchases of common stock in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared with the price at which they may purchase shares through exercise of the overallotment option. If the underwriters sell more shares than could be covered by exercise of the overallotment option and, therefore, have a naked short position, the position can be closed out only by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that after pricing there could be downward pressure on the price of the shares in the open market that could adversely affect investors who purchase in the offering.
•: Penalty bids permit the representative to reclaim a selling concession from a syndicate member when the common stock originally sold by that syndicate member is purchased in stabilizing or syndicate covering transactions to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock in the open market may be higher than it would otherwise be in the absence of these transactions. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected on the Nasdaq Global Market, in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time.

Lock-Up Agreements. Pursuant to certain "lock-up" agreements, we and our executive officers, directors and certain of our other stockholders, have agreed, subject to certain exceptions, not to offer, sell, contract to sell, announce any intention to sell, pledge or otherwise dispose of, enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of, directly or indirectly, or file with the SEC a registration statement under the Securities Act relating to, any common stock or securities convertible into or exchangeable or exercisable for any common stock without the prior written consent of Cowen and Company, LLC, for a period of 180 days after the date of the pricing of the offering. The 180-day restricted period will be automatically extended if (i) during the last 17 days of the 180-day restricted period we issue an earnings release or material news or a material event relating to us occurs or (ii) prior to the expiration of the 180-day restricted period, we announce that we will release earnings results or become aware that material news or a material event will occur during the 16-day period beginning on the last day of the 180-day restricted period, in either of which case the restrictions described above will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition. The exceptions permit us, among other things and subject to restrictions, to: (a) issue common stock or options pursuant to employee benefit plans, or (b) issue common stock upon exercise of outstanding options or warrants. The exceptions permit parties to the "lock up" agreements, among other things and subject to restrictions, to: (a) participate in tenders involving the acquisition of a majority of our stock, (b) participate in transfers or exchanges involving common stock or securities convertible into common stock or (c) make certain gifts. In addition, the

107

lock-up provision will not restrict broker-dealers from engaging in market making and similar activities conducted in the ordinary course of their business.

Directed Share Program. At our request, the underwriters have reserved up to shares of our common stock for sale, at the initial public offering price, through a directed share program to members of our management, and our employees and directors. There can be no assurance that any of the reserved shares will be so purchased. The number of shares available for sale to the general public in the offering will be reduced to the extent the reserved shares are purchased in the directed share program. Any reserved shares of common stock not purchased through the directed share program will be offered to the general public on the same basis as the other common stock offered hereby.

Electronic Offer, Sale and Distribution of Shares. A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters or selling group members, if any, participating in this offering and one or more of the underwriters participating in this offering may distribute prospectuses electronically. The representatives may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters and selling group members that will make internet distributions on the same basis as other allocations. Other than the prospectus in electronic format, the information on these websites is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been approved or endorsed by us or any underwriter in its capacity as underwriter, and should not be relied upon by investors.

Other Relationships. Certain of the underwriters and their affiliates have provided, and may in the future provide, various investment banking, commercial banking and other financial services for us and our affiliates for which they have received, and may in the future receive, customary fees.

108

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Members
Monosol Rx LLC:

We have audited the accompanying balance sheets of Monosol Rx LLC as of December 31, 2006 and 2005, and the related statements of operations, changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2006. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Monosol Rx LLC as of December 31, 2006 and 2005, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 1 to the financial statements, effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 151, Inventory Costs—an Amendment of ARB No. 43, Chapter 4.

(1) Nature of Business and Significant Accounting Policies

Nature of Business

Monosol Rx LLC (Monosol Rx or the Company) was founded on January 21, 2004 and is a drug delivery company specializing in proprietary dissolving thin film drug delivery products. The Company's thin film drug delivery dosage form is similar in size, shape and thickness to a postage stamp and dissolves readily on the tongue for easy use by patients. The Company's thin film drug delivery technology is now used in the over-the-counter, or OTC, marketplace and is currently emerging in the prescription drug market. The Company's films are environmentally friendly given their biodegradable properties and ability to yield inert materials once dissolved in water. For the years ended December 31, 2006, 2005 and 2004, most of the Company's customers were principally located in the Northeastern and Southeastern parts of the United States.

Prior to the formation of Monosol Rx LLC, the activities of the Company were carried out as part of the research and development efforts of Monosol, LLC, a manufacturer of commercial soluble films (the Predecessor). For the time period of January 1, 2004 to January 21, 2004, the results of operations and the assets and liabilities have been assigned to the Company based upon those items specifically related to the Predecessor's business.

During 2004, in connection with the formation of Monosol Rx LLC, the Company received from the Predecessor a capital contribution in the form of assets of $1,793. Additionally, on formation, the Company also received capital of $375 in cash from Monosol RX Genpar, L.P., a private investor, and $2,557 of contributed capital in the form of assets from Kosmos Pharma Limited (Kosmos) in exchange for equity ownership (see note 2).

During 2004, the Company received additional capital contributions from the Predecessor of $6,579 in the form of cash of $4,812 and assets of $1,767.

During 2005, the Company received additional capital contributions from its members as a result of unit purchase warrants issued in connection with two debt issuances. Contributed capital of $3,024 represented the estimated fair values assigned to the unit purchase warrants issued in connection with the debt issuances. An additional $2,180 in contributed capital was recorded as a result of a modification of the terms of certain previously outstanding debt. The modifications were made in connection with the second debt issuance made in 2005. See note 9 for further explanation.

During 2006, the Company received additional capital contributions from its members as a result of unit purchase warrants issued in connection with debt issuances. Contributed capital of $4,668 represented the estimated fair value assigned to the unit purchase warrants issued in connection with the debt issuances.

In October 2006, the Company issued Preferred Members' Interests, Series A and Series A-1 representing a 37.878% interest in the Company. The Series A interestholders contributed $16,887 in cash in exchange for their interest. All of the then existing secured debt holders converted their notes, plus related accrued interest, in to Series A-1 interests, resulting in an additional capital contribution of $12,011.

The Company maintains a production plant in Portage, IN, a research facility in Kingsport TN, a business development office in Washington, DC and its headquarters in Warren, New Jersey.

Significant Accounting Policies

(a): Accounting Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

(b): Cash Equivalents

The Company considers investments with an original maturity of three months or less to be cash equivalents. The Company's cash equivalents were comprised principally of overnight or short-term investment grade debt instruments.

(c): Trade Receivables

The Company's standard credit terms are 30 days for customers in the United States and 45 days for international customers. Trade receivables are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a periodic basis. Management determines the allowance for doubtful accounts by identifying troubled accounts and in the absence of historical experience, applying an estimate that management believes is a reasonable indicator of future potential losses. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. The following table presents the changes in the allowance for bad debts account for the years ended December 31, 2006, 2005 and 2004.

	Balance Beginning of Year	Charged to Costs and Expenses	Acquisitions	Deductions	Balance at End of Year
Allowance for bad debts
2004	—	—	—	—	—
2005	—	381	—	381	—
2006	—	16	—	—	16

(d): Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis.

Inventories are evaluated periodically and the cost of any nonusable inventory is written-off to expense. In addition, the Company reserves for any inventory where carrying value may be in excess of its estimated realizable value, or where the items could potentially be nonusable. Charges for such write-offs and reserves are recorded as a component of cost of goods sold.

(e): Property and Equipment

Property and equipment are stated at cost. Depreciation for equipment, furniture, and fixtures is calculated using the straight-line method over the estimated useful lives of the assets. Machinery and equipment are depreciated over 2 to 15 years and furniture and fixtures are depreciated over 5 to 10 years. Leasehold improvements are amortized over the shorter of the lease term or their estimated useful lives. Total depreciation for the years ended December 31, 2006, 2005, and 2004 was $1,730, $479 and $295, respectively.

F-9

(f): Other Assets

Other assets consist principally of unapplied vendor credits available for application against the purchase price of additional machinery configured similarly to that currently used by the Company, and restricted cash.

(g): Intangible Asset

The technology intangible relates to composition and process technology used in edible soluble film manufacturing. It was acquired as part of the Kosmos Pharma Limited asset purchase in 2004 (see note 2). The Company amortizes the technology intangible using the straight-line method over 10 years, which is the expected useful life of the associated products.

(h): Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs reflect costs incurred for the Company's internal proprietary research and development projects as well as costs incurred under arrangements with third parties for which the Company generates co-development and research fees. All research and development costs are presented within operating expenses. Research and development expenses amounted to $1,993, $1,258, and $1,010 for the years ended December 31, 2006, 2005, and 2004, respectively.

(i): Income Taxes

Monosol Rx LLC is a limited liability company and its owners are referred to as members. Limited liability companies operate under sections of federal and state income tax law which provide that, in lieu of company-level income taxes, the members separately account for their pro rata shares, as allocated in accordance with the members' operating agreement, of the Company's items of income, deductions, losses, and credits. No income taxes have been recognized in the accompanying financial statements except for certain state taxes, which are immaterial and included in general and administrative expense.

(j): Impairment of Long-Lived Assets

In accordance with Statement of Financial Accounting Standards (SFAS) No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, long-lived assets, such as property and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet.

In 2006, as a result of management's evaluation of the recoverability of the carrying value of its property and equipment, the Company recorded an impairment charge of $132.

F-10

(k): Revenue Recognition

The Company recognizes revenue when products are shipped and the customer takes ownership and assumes risk of loss, collection of the related receivable is probable, persuasive evidence of an arrangement exists, and the sales price is fixed or determinable. The Company occasionally uses a third party to complete the packaging process. In these instances, revenue is recognized when the completed product is shipped from the third party. In the case of co-development and research fees, revenue is recognized when appropriate contractual milestones are realized, contractual amounts for those services are billed, and collection of related receivables is probable.

(l): Asset Retirement Obligations

SFAS No. 143, Accounting for Asset Retirement Obligations, addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. The Company's asset retirement obligation consists of estimated future spending to remove certain leasehold improvements and return the leased facility to its original condition. Spending estimates are discounted at the credit-adjusted risk-free rate. The Company records an Asset Retirement Obligations (ARO) asset (a component of property and equipment) associated with the discounted liability. The ARO asset is amortized on the straight-line method over the lesser of its expected life or the lease term, and the ARO liability is accreted to the projected spending date.

(m): Reclassifications

Costs written off for inventory excess and obsolescence in 2005 have been reclassified from general and administrative expenses to cost of goods sold to conform to the 2006 presentation.

(n): Change in Method of Accounting for Patent Costs

In 2006, the Company elected to change its method of accounting for patent costs. In prior years, the Company capitalized all external costs incurred in seeking patent protections, consisting primarily of legal fees for patent applications, and commenced amortization upon approval of the patent. Internal costs related to patent applications were expensed as incurred. Beginning in 2006, the Company adopted a policy of expensing both internal and external patent application costs as incurred. Legal costs incurred to successfully defend an existing patent are capitalized and amortized over the remaining life of the patent. Legal costs related to an unsuccessful outcome are expensed when the outcome is known. The comparative financial statements of prior years have been adjusted to reflect the change in accounting policy retroactively.

(o): Recently Adopted Accounting Standards

In December 2004, the Financial Accounting Standards Board (FASB) issued FASB Statement No. 123 (revised 2004), Share-Based Payment, which addresses the accounting for transactions in which an entity exchanges its equity instruments for goods or services, with a primary focus on transactions in which an entity obtains employee services in share-based payment transactions. This Statement is a revision to Statement 123 and supersedes Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and its related implementation guidance. This Statement requires measurement of the cost of employee services received in exchange for stock-based awards using the grant-date fair value of the awards. Incremental compensation costs arising from subsequent modifications of awards after the grant date must

F-11

also be recognized. The Company adopted this Statement on January 1, 2006 under the modified prospective method of application. Under that method, the Company will recognize compensation costs for new grants of share-based awards, awards modified after the effective date, and the remaining portion of the fair value of the unvested awards at the adoption date. The adoption had no impact on the Company's operating income or net loss.

Effective January 1, 2006, the Company adopted FASB Statement No. 151, Inventory Costs—an Amendment of ARB No. 43, Chapter 4 (Statement 151). Statement 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage) requiring that those items be recognized as current period charges. In addition, Statement 151 requires that allocation of fixed production overheads be based on the normal capacity of the production facilities. Prior to the adoption of Statement 151, the Company's inventory cost included fixed overhead costs determined as a percentage of direct costs.

(p): Recently Issued Accounting Standards

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a threshold of more-likely-than-not for recognition of tax benefits of uncertain tax positions taken or expected to be taken in a tax return. FIN 48 also provides related guidance on measurement, derecognition, classification, interest and penalties, and disclosure. The provisions of FIN 48 will be effective for the Company on January 1, 2007, with any cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. The Company is in the process of assessing the impact of adopting FIN 48 on its results of operations and financial position, but does not believe that it will be significant.

(2) Purchase of Assets from Kosmos Pharma Limited

On January 22, 2004, the Company purchased substantially all of the assets of Kosmos Pharma Limited (Kosmos), a drug research company, in exchange for the assumption of certain liabilities and the issuance of limited liability interests in the Company. At the date of purchase, Kosmos had no commercially viable products, but had developed certain development applications. The Company believed that the combination of the Predecessor's production capabilities and Kosmos' technology would accelerate the growth of the Predecessor.

The following table presents a summary of the assets purchased and the liabilities assumed based on their approximate fair value:

Receivables		$	1,196
Property and equipment			252
Technology intangible asset			2,358

	Total assets acquired		3,806

Accounts payable			345
Long-term debt			904

	Total liabilities assumed		1,249

	Net assets acquired	$	2,557

F-12

Fair value for property and equipment and the technology intangible were determined using estimated replacement cost.

(3) Cash and Liquidity

At December 31, 2006, the Company had $15,256 of cash. Management believes, even absent any actions to access the capital markets, that the Company has sufficient cash resources to meet its needs at least through December 31, 2007.

(4) Major Customers

Most of the Company's customers are located in the United States and Europe. Customers are considered major customers when sales exceed 10% of the Company's total net sales for the year or outstanding receivable balances exceed 10% of total receivables. The Company had four major customers with sales totaling $2,509 for the year ended December 31, 2006 and outstanding receivable balances totaling $563 at December 31, 2006. The Company had no major customers for the year ended December 31, 2005. The Company had one major customer with sales of $1,774 for the year ended December 31, 2004 and an outstanding receivable balance from this customer of $1,015 at December 31, 2004.

(5) Trade Receivables

(8) Other Assets

As of December 31, 2006, the Company had $100 in restricted cash on deposit in support of a stand-by letter of credit issued in favor of the Indiana Board of Pharmacy. This is a statutory requirement based on the regulations of the Indiana Board of Pharmacy. Additionally, the Company is entitled to credits from a supplier of machinery. At December 31, 2006 and 2005, the Company was entitled to $200 and $496 of vendor credits, respectively, to be applied towards the purchase of production machinery configured similarly to the machinery it currently uses. During June 2006, the Company reconfigured a portion of its production, machinery, and equipment. As a result, $296 of vendor credits were no longer usable and were charged off. The Company also has a purchase obligation related to the machinery. See note 11.

(9) Intangible Asset

The following table presents a summary of the intangible asset at December 31, 2006 and 2005.

Less current maturities		(278	)

	$	5,925

During 2006, the Company repaid the unsecured note due to member and the Tranche A & B Notes were converted to Series A-l Preferred Interests (see below).

The unsecured note was assumed as a result of the Kosmos transaction (see note 2) and was payable to a related party.

Tranche A & B Notes

In 2005, the Company issued $5,000 of notes payable (Tranche A Notes) along with stock purchase warrants. The Tranche A Notes bore 15% payment in kind (PIK) interest with a maturity date of 2010. Management held $275 of the Notes, with the remainder held by affiliates of the members of the Company. The estimated fair value of the warrants at the date of issue was $431 and the Company recognized $25 of compensation expense related to the warrants held by management. In August 2005, the Company modified the Tranche A Notes by reducing the interest rate to 4.33% and extending the maturity date to 2015. The modification of the Tranche A note terms was considered a significant debt modification and resulted in the recognition of a capital contribution in the amount of $2,180.

In August 2005, the Company completed a financing transaction in which it issued $5,500 of notes payable (2005 Tranche B Notes) and stock purchase warrants to an affiliate of the Company. The notes were issued with a maturity date of 2015 and 4% payment-in-kind (PIK) interest. The warrants were recorded at fair value and gave rise to the recognition of a discount on the 2005 Tranche B Notes of $2,567.

During 2006, the Company issued $10,000 of notes payable (2006 Tranche B Notes) along with warrants to several investors, including affiliates of the Company. The notes were issued with a 10-year term and 4% PIK interest. The warrants were recorded at fair value and gave rise to the recognition of a discount on the 2006 Tranche B Notes of $4,668.

The warrants are immediately exercisable at price of $0.01 per unit and expire at various times in 2015 and 2016. At December 31, 2006, the warrants represent a 35.5% ownership interest in the Company.

In October and November 2006, the Tranche A and B Notes, with an original principal amount of $20,500 and accrued interest of $1,027, were converted to Series A-l Preferred Interests.

(11) Commitments and Contingent Liabilities

(a) Leases:

The Company has entered into various lease agreements for production and research facilities and offices. Most leases contain renewal options; some contain purchase options and some require the Company to pay for taxes, maintenance and operating expenses.

Production and Research Facilities:

The Company leases its current production facility in Portage, Indiana, which houses research and development offices and current good manufacturing practices, or cGMP, manufacturing operations. Prior to September 2006, the property was leased through the Predecessor and rent was charged to the Company by the Predecessor. In September 2006, the Predecessor, with the landlord's agreement and acceptance, assigned to the Company all rights and obligations under the existing lease. As part of the assignment, the Predecessor agreed to guarantee the lease payment through March 2008. See note 18.

In October 2006, the Company entered into a lease for a 73,000 square foot cGMP facility (Ameriplex) in Portage, Indiana. The Ameriplex facility will become the primary research, development, and manufacturing facility for the Company. The current term of the lease expires in March 2012, with options to extend through March 2021. The lease contains a right of first refusal to purchase the facility.

The Company leases a technology development laboratory in Kingsport, Tennessee. The lease expires in December 2009.

Office Facilities:

In July 2006, the Company entered into a lease for its headquarters in Warren, New Jersey. The lease expires in August 2011.

The Company is a guarantor of a lease for office space in Washington, D.C. The underlying lease was entered into by a consultant to the Company and extends through May 2007.

Rent expense totaled $360, $233, and $124 for the years ended December 31, 2006, 2005, and 2004, respectively.

The following is a schedule of future minimum lease payments under operating leases as of December 31, 2006:

		Amount
Year:
	2007	$	588
	2008		536
	2009		539
	2010		532
	2011		556
	Thereafter		128

		$	2,879

F-16

(b) Equipment Purchase Obligations

The Company has entered into an agreement to purchase in 2007 a new film coating line in the amount of $3,690 to fulfill production requirements under a commercial supply agreement. The customer that is a party to the supply agreement is obligated to make capacity payments over two years that equal the cost of the equipment and other capital expenditures related to its installation.

(12) Employee Benefit Plans

The Company sponsors a defined contribution 401(k) plan covering all full-time employees. Participants may contribute up to 50% of their salary not to exceed applicable statutory limitations. The Company makes matching contributions to the plan equal to 100% of the first 6% contributed by employees. The Company may also make a discretionary profit sharing contribution to the plan. In 2006, the Company's matching contributions to the plan were $169. The discretionary profit-sharing contribution totaled $0 in 2006. In 2005, the Company's matching contributions to the plan were $64. The Company also made a discretionary profit-sharing contribution of 9% of annual compensation for employees who had completed more than one year of service. The discretionary profit-sharing contribution totaled $101 in 2005. In 2004, the Company's matching contributions to the plan were $22. The Company also made a discretionary profit-sharing contribution of 9% of annual compensation for employees who had completed more than one year of service in 2004. The discretionary profit-sharing contribution totaled $31.

(13) Research and Development Arrangements

The Company periodically enters into arrangements to test the applicability of various products on thin film. These arrangements are usually for a finite period of time and are directed at a certain defined result. The fees charged are usually on a cost-plus basis. These arrangements may or may not lead to future research and development arrangements or product production. In 2006, 2005, and 2004, revenue derived from these types of arrangements was $950, $665, and $100, respectively. In 2006, 2005, and 2004, research and development expenses related to co-development and research fees were $799, $359 and $69, respectively.

(14) Performance Units Plan

The Company has established two Performance Unit Plans (the Plans) for the purpose of enhancing the long-term growth in earnings of the Company by providing incentives to key employees and other service providers of the Company. The Plans authorize grants of up to 22,796 performance units and can be modified at the Company's discretion to make additional performance units available. Performance units may be granted with a base value equal to their estimated fair value on the date of grant. The base value and fair value are determined by the Company's board of directors. The performance units granted to employees are equity classified instruments. The performance units granted to consultants are liability classified instruments. All performance units are awarded upon a change in control or an Initial Public Offering (IPO) of the Company and vest over either a two or a three-year period with accelerated vesting upon a change in control or an IPO of the Company. Vested units can be redeemed for cash or in the form of the same equity instruments received by the Company or members of the Company at the time of a change in control or an IPO, at the Company's discretion. The payment to a participant is based on the spread between the fair value at the time of a change in control and the base value of the performance units the participant has been awarded.

F-17

There were 21,215, 3,750, and 2,775 performance units issued to plan participants that would be awarded in the event of a change in control or IPO of the Company as of December 31, 2006, 2005, and 2004, respectively. No equity or liability was recorded for the performance units outstanding at December 31, 2006 and 2005, as the certain conditions that allow award of the units and redemption, such as change in control, were not deemed probable at that time.

Certain participants of the plan, principally senior management, have been granted protection against future dilution of their interests (dilution protection). As of December 31, 2006, 19,776 of the outstanding units are covered by dilution protection through June 2007 or the completion of an IPO of the Company, whichever comes first. In addition, during 2006, 13,599 units were issued due to dilutive events or changes in the capital structure of the Company, and 3,380 units were issued in connection with new hires.

(15) Related-Party Transactions

Holders of the Tranche A and B Notes are affiliates of the Company. See note 9.

At December 31, 2006 and 2005, $0 and $10, respectively, were due to the Predecessor as accounts payable.

At December 31, 2006, $200 was due from the Predecessor as other receivables. In December 2006, the Company sold an asset with a book value of $416 to the Predecessor for $200. The asset was originally part of Monosol Rx LLC's capital contribution in 2004 and was found to be unsuitable for use in pharmaceutical film casting. Prior to the transaction, in order to determine an appropriate sale price for the asset, the Company obtained independent estimates from dealers in the secondary market, the sales price was in excess of the estimates obtained. See note 18.

Interest expense on the term note with the interestholder was $22, $38, and $41 for the years ended December 31, 2006, 2005, and 2004, respectively.

The statements of operations include certain costs allocated by the Predecessor. Charges for rent, insurance, employee fringe benefits, and other overhead costs are based on the ratio of payroll expense for the Company's or the Predecessor's employees to aggregate payroll expense for the Predecessor employees. In the opinion of management, the costs charged have been allocated on a basis that is believed to be reasonable within the structure of the Predecessor. However, the costs charged are not necessarily indicative of the level of expenses that might have been incurred if the Company and the Predecessor had operated as a standalone entity. The total amount of costs allocated to the Company was $250, $696, and $727 for 2006, 2005, and 2004, respectively.

In conjunction with the Company's purchase of all of the assets of Kosmos, Dr. Richard Fuisz and his son, Joseph Fuisz, Esq., significant shareholders in Kosmos, entered into consulting agreements with the Company. These consulting agreements were each for a three-year term and provided for a monthly and annual fee of $13 and $160, respectively, plus the reimbursement of certain expenses.

In September 2006, the consulting agreement between the Company and Dr. Fuisz was extended through September 2009 with substantially the same terms. The contract between the Company and Joseph Fuisz, Esq. was terminated and Mr. Fuisz became an employee of the Company.

F-18

(16) Asset Retirement Obligations

SFAS No. 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement cost. The Company's asset retirement obligation consists of estimated future spending related to removing certain leasehold improvements at its Portage, Indiana laboratory and returning the facility to its original condition.

Below is a schedule of the Company's liability for asset retirement obligations for the year ended December 31, 2006:

	Amount
Balance at December 31, 2005	$	—
Liability incurred, September 2006		85
Accretion		2

Balance at December 31, 2006	$	87

For the year ended December 31, 2006, the Company recorded expense of $14 included in depreciation expense related to the ARO asset.

(17) Preferred Interests

In November 2006, the Company closed a Private Placement Offering for $38,414 Series A and Series A-l Preferred Interests representing a 37.9% ownership in the Company. The interests were purchased by several investors, including affiliates of the Company. The balance of the Company's equity is represented by common interests.

The Company received $16,887 in cash proceeds from the Series A offering. The proceeds are to be used to fund research and development activities, capital expenditures for facilities, expansion of manufacturing capabilities and working capital needs. The Series A-l preferred interests were issued in settlement of all amounts due on the Tranche A and B Notes issued in 2005 and 2006, consisting of $20,500 in principal along with accrued interest.

The Series A interests rank senior to the Series A-l interests and common interests with respect to payment of dividends and amounts due upon liquidation, dissolution, or winding up of the Company. The Series A-l interests are senior to the common interests with respect to dividends and liquidation.

The Series A and A-l interests hold the same voting rights as the common interests.

The Company is required to receive the written consent of more than 50% of the Preferred Interests prior to:

•: Liquidating, dissolving or winding up the Company;
•: Amending or repealing the LLC Agreement; and
•: Creating or authorizing a security senior to the preferred interest or increasing the authorized number of preferred interests.

(18) Subsequent Events

In January 2007, the landlord of the Portage, Indiana production facility released the Predecessor from its guarantee in consideration of the Company providing a security deposit in the amount of three months rent.

In January 2007, the Company issued an additional 210 performance units to various employees. The performance units are subject to the terms of the Performance Unit Plan, as described in note 13.

In February 2007, the Company received the $200 classified as other receivables from the Predecessor.

In April 2007, the holders of the warrants issued in 2005 and 2006 in connection with the Tranche A & B Notes, (see Note 10) exercised their rights to purchase common membership interests in Monosol Rx LLC. An additional 55,785 membership interests were issued for $155.

In May 2007, the Company amended and restated its Executive Employment Agreement with Joseph Fuisz and amended its Consulting Agreement with Dr. Richard Fuisz. Dr. Fuisz's Consulting Agreement was amended to require the Company to pay him a fee of $100 upon the effectiveness of a registration statement for an initial public offering of MonoSol Rx, Inc., if the effectiveness occurs by December 31, 2007. See note 19. Joseph Fuisz's amended and restated Executive Employment Agreement terminates on December 31, 2007, and provides for a consulting agreement between Joseph Fuisz and the Company commencing January 1, 2008, and ending December 31, 2008.

The agreement that amended Dr. Fuisz's Consulting Agreement with the Company also provided for the Company's transfer of certain intellectual property to a new limited liability company of which Dr. Fuisz will own a 55% interest and the current equity interest holders of Monosol Rx LLC will own a 45% interest. The intellectual property transferred is not related to thin film products. Thus management does not believe that it has value to the Company in its current form.

We have also agreed to indemnify Dr. Fuisz to the same extent we have agreed to indemnify our officers and directors.

(19) Planned Transactions (unaudited)

The Company is planning to merge with and into a newly formed entity, MonoSol Rx, Inc. The merger is in connection with MonoSol Rx, Inc. filing a Registration Statement relating to the proposed public offering of its common stock. Immediately after merger, but prior to the offering the Company's common interests, preferred interests and outstanding performance units will be converted to the Common Stock of MonoSol Rx, Inc.

Item 14. Indemnification of directors and officers.

Our certificate of incorporation provides that none of our directors will be personally liable to us or our stockholders for monetary damages for breaches of fiduciary duty, except for (i) breach of our director's duty of loyalty to us or our stockholders, (ii) acts or omissions that are not in good faith, or which involve intentional misconduct or a knowing violation of law, (iii) unlawful payments of dividends, stock purchases, or redemptions as provided in Section 174 of the Delaware General Corporation Law, or DGCL, or (iv) any transaction from which the director derives an improper personal benefit.

Our bylaws provide that, to the fullest extent permitted by applicable law, we will indemnify, hold harmless, and advance expenses to any person that is made or threatened to be made a party to an action or proceeding by reason of the fact that he or she is or was one of our directors or officers. However, we are not required to indemnify such person for a proceeding initiated by or on behalf of such person, unless our board of directors authorizes indemnification for that particular proceeding.

Section 145 of the DGCL provides that a corporation has the power to indemnify a director, officer, employee, or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys' fees), judgments, fines, and amounts paid in settlements actually and reasonably incurred by the person in connection with a threatened, pending, or completed action, suit or proceeding to which he or she is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, indemnification is limited to expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and no indemnification shall be made with respect to any claim, issue, or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but

II-1

in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

In addition, Section 145 of the DGCL requires that, to the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit, or proceeding described above, or defense of any claim, issue, or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith.

Section 145 of the DGCL also provides that expenses (including attorneys' fees) incurred by an officer or director in defending any civil, criminal, administrative, or investigative action, suit, or proceeding may be advanced by the corporation upon receipt of an undertaking by such person to repay such amount if it is ultimately determined that such person is not entitled to indemnification by the corporation under Section 145 of the DGCL.

We expect to obtain insurance policies under which our directors and officers are insured, within the limits and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities which may be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being or having been directors or officers.

Prior to the completion of this offering, we will enter into indemnification agreements with each of our officers and directors under which we agreed to indemnify each of them against: (a) expenses, judgments, and settlements paid in connection with third-party claims and (b) expenses and settlements paid in connection with claims on our behalf, in each case provided that the director acted in good faith. In addition, we will agree to indemnify each director to the extent permitted by the DGCL, our certificate of incorporation and our bylaws against all expenses, judgments, and amounts paid in settlement unless the director's conduct constituted a breach of his or her duty of loyalty to the stockholders. Subject to the director's obligation to pay us in the event that he or she is not entitled to indemnification, we will pay the expenses of the director prior to a final determination as to whether the director is entitled to indemnification.

Reference is also made to the Underwriting Agreement filed as Exhibit 1.1 to the Registration Statement for information concerning the underwriters' obligation to indemnify us and our officers and directors in certain circumstances.

Item 15. Recent sales of unregistered securities.

Set forth below is information regarding securities sold by us since March 1, 2004 which were not registered under the Securities Act of 1933, as amended, or Securities Act.

From February 2005 to April 2005, we conducted an offering in which we issued and sold promissory notes and related warrants to seven investors for an aggregate offering price of approximately $5,000,000 in exchange for cash.

From August 2005 to November 2006 we conducted on offering in which we issued and sold promissory notes and related warrants to two investors for an aggregate offering price of approximately $15,500,000 in exchange for cash.

In September 2006, we issued and sold two series of preferred membership interests in Monosol Rx LLC to nine investors for an aggregate offering price of approximately $38,913,600 in exchange for cash. A portion of the proceeds of this offering was used to retire our outstanding indebtedness, including accrued interest, under the promissory notes described above.

No underwriters were involved in the foregoing sales of securities. The securities were issued to U.S. investors in reliance upon the exemption from registration requirements of the Securities Act, as set forth in Section 4(2) under the Securities Act and Rule 506 of Regulation D promulgated

II-2

thereunder relating to sales by an issuer not involving any public offering to the extent an exemption from such registration was required. The purchaser of our notes, warrants, and preferred membership interests described above represented to us in connection with their purchase that they were accredited investors and were acquiring the securities for investment and not distribution, that they could bear the risks of the investment, and could hold the securities for an indefinite period of time.

The purchasers received written disclosures that the securities had not been registered under the Securities Act and that any resale must be made pursuant to a registration or an available exemption from such registration. The sales of these securities were made without general solicitation or advertising.

Item 17. Undertakings.

(1) The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

(2) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(3) The undersigned registrant hereby undertakes that:

(i): For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to

II-4

Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(ii): For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
