## ITEM 1. BUSINESS

## OVERVIEW

We are a global biotechnology company that invests in scientific innovation to create transformative medicines for people with serious diseases with a focus on specialty markets.

## Cystic Fibrosis

Our goal is to develop treatment regimens that will provide benefits to all people with cystic fibrosis, or CF, and will enhance the benefits currently provided to people taking our medicines. Our marketed medicines are TRIKAFTA/KAFTRIO (exelacaftor/tezacaftor/ivacaftor and ivacaftor), SYMDEKO/SYMKEVI (tezacaftor/ivacaftor and ivacaftor), ORKAMBI (lumacaftor/ivacaftor) and KALYDECO (ivacaftor). Our triple combination regimen, TRIKAFTA/KAFTRIO, was approved in 2019 in the United States, or U.S., and in 2020 in the European Union, or E.U. Collectively, our four medicines are approved to treat the majority of the approximately 83,000 people with CF in North America, Europe and Australia. We are evaluating our medicines, including our triple combination regimen, in additional patient populations, including younger children, with the goal of having small molecule treatments for up to 90% of people with CF. We are pursuing genetic therapies to address the remaining 10% of people with CF.

## Research and Development

Our goal is to identify and develop innovative medicines by combining transformative advances in the understanding of human disease and in the science of therapeutics to advance human health. Our research and early development strategy includes advancing multiple compounds from each program into early clinical trials and evaluating the resulting data to inform drug discovery and development, with the goal of bringing best-in-class therapies to patients. This strategy and approach is intended to increase the likelihood of successfully bringing transformative medicines to patients.

## Small Molecule Programs

Alpha-1 Antitrypsin Deficiency. We are focused on identifying and developing multiple drug candidates with the potential to increase the levels of functional alpha-1 antitrypsin, or AAT, in the blood, to address the lung and liver manifestations of AAT deficiency. Enrollment is ongoing in a Phase 2 proof-of-concept trial for VX-864, an investigational small molecule corrector for the treatment of AAT deficiency. We expect data from this clinical trial in the first half of 2021.

APOL1-Mediated Kidney Diseases. We are evaluating inhibitors of APOL1 function to reduce levels of protein in the urine, or proteinuria, in people with serious kidney diseases, including focal segmental glomerulosclerosis, or FSGS, and other APOL1-mediated kidney diseases. In 2020, we initiated a Phase 2 proof-of-concept clinical trial designed to evaluate the reduction in proteinuria in people with APOL1-mediated FSGS after treatment with VX-147. Enrollment in this clinical trial is ongoing and we expect data in 2021.

Pain. We believe that NaV1.8 inhibitors have the potential to provide an effective non-opioid treatment for pain. We are advancing a portfolio of NaV1.8 inhibitors through pre-clinical and early clinical development.

## Cell and Genetic Therapies

Sickle cell disease and transfusion-dependent beta thalassemia. We are co-developing CTX001, an investigational CRISPR/Cas9-based gene-editing therapy for sickle cell disease, or SCD, and transfusion-dependent beta thalassemia, or TDT, with CRISPR Therapeutics AG, or CRISPR. Enrollment and dosing are ongoing in two Phase 1/2 clinical trials to evaluate CTX001 as a potential one-time curative therapy for people with severe SCD and TDT. In December 2020, we announced positive interim data from 10 people treated with CTX001 and that a total of thirteen people with TDT and seven people with severe SCD have been dosed with CTX001. We expect to complete enrollment in both clinical trials in 2021.

Type 1 Diabetes. In 2019, we acquired Semma Therapeutics, Inc., or Semma, and established preclinical cell therapy programs for type 1 diabetes, or T1D. We are pursuing two programs for the transplant of functional islets into patients: transplantation of islet cells alone, using immunosuppression to protect the implanted cells, and implantation of the islet cells inside a novel immunoprotective device. The FDA has cleared our Investigational New Drug Application, or IND, for



VX-880, the first program (transplantation of islet cells alone), and we expect to initiate a Phase 1/2 clinical trial evaluating VX-880 in the first half of 2021.

Duchenne muscular dystrophy, or DMD, and myotonic dystrophy type 1, or DM1. In 2019, we acquired Exonics Therapeutics, Inc., or Exonics, and expanded our collaboration with CRISPR enabling the establishment of preclinical genetic therapy programs for DMD and DM1.

We plan to continue investing in our research and development programs and fostering scientific innovation by continuing to identify additional drug candidates through our internal research efforts and investing in business development transactions to access emerging technologies, drugs and drug candidates.

## CYSTIC FIBROSIS

## Background

CF is a life-shortening genetic disease caused by a defective or missing CFTR protein resulting from mutations in the CFTR gene. To develop CF, children must inherit two defective CFTR genes, which are referred to as alleles; one allele is inherited from each parent. The vast majority of patients with CF carry at least one of the two most prevalent mutations, the F508del mutation and the G551D mutation. The F508del mutation results in a defect in the CFTR protein in which the CFTR protein does not reach the surface of the cells in sufficient quantities and does not adequately transport chloride ions. The G551D mutation results in a defect in the CFTR protein in which the defective protein reaches the surface of a cell but does not adequately transport chloride ions across the cell membrane.

The absence of working CFTR proteins results in poor flow of salt and water into and out of cells in a number of organs, including the lungs. As a result, thick, sticky mucus builds up and blocks the passages in many organs, leading to a variety of symptoms. In particular, mucus builds up and clogs the airways in the lungs, causing chronic lung infections and progressive lung damage. CFTR potentiators such as ivacaftor and VX-561 increase the probability that the CFTR protein channels open on the cell surface, increasing the flow of salt and water into and out of the cell. Our CFTR correctors, such as lumacaftor, tezacaftor, and elexacaftor, help CFTR proteins reach the cell surface.



## Our Medicines

Our medicines, TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, ORKAMBI and KALYDECO, are collectively approved to treat the majority of people with CF in North America, Europe and Australia. Our approved medicines, including information regarding the indication and age groups for which the medicine is approved, are set forth in the table below.

<table><tr><td>Product</td><td>Scientific Name</td><td>Region/Initial Approval</td><td>Indication</td><td>Eligible Age Group</td></tr><tr><td>trikafta</td><td>elexacaftor/tezacaftor/ivacaftor and ivacaftor</td><td>U.S. (2019)</td><td>People with CF with (i) at least one F508del mutation, or (ii) another mutation that is responsive to elexacaftor/tezacaftor/ivacaftor and ivacaftor</td><td>12 years of age and older</td></tr><tr><td>kaftrio</td><td>elexacaftor/tezacaftor/ivacaftor and ivacaftor</td><td>E.U.

In addition to the E.U. and the U.S., we market our products in additional countries, including the United Kingdom, Australia, Switzerland, Israel, and Canada. Currently, our medicines treat almost half of the people with CF in these geographies. We continuously seek to increase the number of patients eligible and able to receive our current medicines through label expansions, approval of new medicines and expanded reimbursement. Since the beginning of 2020, activities in support of these efforts include:

## TRIKAFTA/KAFTRIO

- In August, the European Commission granted marketing authorization for KAFTRIO to treat people with CF 12 years of age and older with one F508del mutation and one minimal function mutation, or two F508del mutations.

- The FDA expanded the eligibility for TRIKAFTA to include people with CF 12 years of age and older with certain mutations that are responsive to TRIKAFTA based on in vitro data.

- In January 2021, the FDA accepted our supplemental New Drug Application, or sNDA, for TRIKAFTA for the treatment of children 6 to 11 years of age with at least one F508del mutation or have certain mutations that are responsive to TRIKAFTA based on in vitro data. The FDA granted Priority Review of the sNDA.



- Swissmedic, the Swiss Agency for Therapeutic Products, granted marketing authorization and a reimbursement agreement was reached for TRIKAFTA in Switzerland for the treatment of people with CF 12 years of age and older who have two copies of the F508del mutation, or one F508del mutation and one minimal function mutation.

• Health Canada accepted for Priority Review a New Drug Submission for TRIKAFTA for the treatment of people with CF 12 years of age and older.

## SYMDEKO/SYMKEVI

- The European Commission approved SYMKEVI for the treatment of people with CF 6 years of age and older with two copies of the F508del mutation, or one F508del mutation and certain residual function mutations.

• The FDA approved SYMDEKO for additional responsive mutations in people with CF 6 years of age and older.

## ORKAMBI

- We entered into a reimbursement agreement with the Swiss government for ORKAMBI for the treatment of people with CF 2 years of age and older, and for SYMDEKO for the treatment of people 12 years of age and older in Switzerland.

## KALYDECO

- The FDA approved KALYDECO for treatment of infants with CF four months of age and older who have at least one mutation in their CFTR gene that is responsive to KALYDECO.

- The European Commission approved KALYDECO for treatment of infants with CF four months of age and older who have the R117H mutation or certain gating mutations.

• The FDA approved KALYDECO for treatment of infants with CF four months of age and older with additional responsive mutations.

## CF PIPELINE

- VX-561, a CFTR potentiator we acquired from Concert Pharmaceuticals, Inc., and VX-121, a CFTR corrector, are being evaluated in Phase 2 clinical development.

- We continue to identify and develop additional CFTR modulators with the goal of achieving carrier levels of CFTR activity for the 90% of people with CF who respond to CFTR modulators.

- We continue to research genetic therapies, such as messenger ribonucleic acid, or mRNA, and gene-editing approaches, to treat the remaining 10% of people who do not make CFTR protein and, as a result, are not eligible for CFTR modulators.

- We extended our collaboration with Moderna, Inc., or Moderna, aimed at the discovery and development of mRNA therapeutics for the treatment of CF. In addition, we entered into a new collaboration with Moderna for the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies to lung cells for the treatment of CF.

## RESEARCH AND DEVELOPMENT PROGRAMS

We invest in research and development in order to discover and develop transformative medicines for people with serious diseases with a focus on specialty markets. Our strategy is to combine transformative advances in the understanding of human disease and the science of therapeutics in order to discover and develop new medicines. Our approach to drug discovery has been validated through our success in moving novel small molecule drug candidates into clinical trials and obtaining marketing approvals for TRIKAFTA/KAFTRIO, KALYDECO, ORKAMBI and SYMDEKO/SYMKEVI for the treatment of CF and INCIVEK (telaprevir) for the treatment of hepatitis C infection. In addition, we have achieved clinical proof of concept for Nav1.8 inhibition in the treatment of three different pain models, and for gene-editing of BCL11A for the treatment of beta thalassemia and SCD.



We continue to research and develop small molecule drug candidates for the treatment of serious diseases, including CF, AAT deficiency, APOL1-mediated kidney diseases, and pain. Our research and development approach includes advancing multiple small molecules into clinical trials, pursuing multiple modalities and evaluating clinical and non-clinical data to inform drug discovery and development, with the goal of bringing best-in-class therapies to patients.

Over the last several years, we have expanded our capabilities to include additional innovative therapeutic approaches with a focus on cell and genetic therapies, which have the potential to treat, and in some cases, cure diseases by addressing the underlying cause of the disease. We have expanded our capabilities by increasing our internal investment in cell and genetic therapies, including plans to establish a new research and development site in Boston that will focus primarily on cell and genetic therapies. In addition, we have made several significant investments in external innovation, including:

• our collaboration with CRISPR to access and develop therapeutics based on the CRISPR gene-editing technology;

• our establishment of cell therapy programs for T1D through our acquisition of Semma;

• our establishment of genetic therapy programs for DMD and DM1, through our acquisition of Exonics;

• our collaboration with Moderna for the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies; and

• our collaboration with Affinia Therapeutics, Inc., or Affinia, to engineer novel adeno-associated virus (AAV) capsids to deliver gene therapies.

The experience we gained developing medicines for CF and our analysis of research and development programs conducted by other companies in our industry have shaped a disciplined strategy that guides our investments in research and development and external innovation that focuses on:

• transformative treatments for life-threatening diseases with a high unmet medical need;

• targets validated as playing a causal role in the human biology of a disease;

• innovative therapeutic approaches to addressing those targets;

• biological assays and clinical biomarkers that we believe will be predictive of clinical responses; and

• efficient clinical and regulatory paths to bring new medicines to patients.

To augment our internal programs, we plan to continue acquiring businesses and technologies and collaborating with biopharmaceutical and technology companies, leading academic research institutions, government laboratories, foundations and other organizations to advance research in our areas of therapeutic interest as well as to access technologies needed to execute on our strategy. We have established such relationships with organizations around the world and intend to extend and leverage that experience to further our research efforts to discover transformational medicines for serious diseases. We will continue to identify and evaluate potential acquisitions and collaborations that may be similar to or different from the transactions that we have engaged in previously.

## Small Molecule Programs

## Alpha-1 Antitrypsin Deficiency

AAT deficiency is caused by mutations in the SERPINA1 gene that encodes the AAT protein. People who inherit two mutant SERPINA1 alleles (one from each parent) develop AAT deficiency. Most people who develop AAT deficiency have two copies of the mutant Z allele. The mutations result in a defect in the AAT protein in which the protein does not fold correctly. This folding defect causes the AAT protein to accumulate in the liver (where it is produced at high levels), which can cause liver damage. As a result, the protein fails to reach other organs in adequate quantity and function, particularly in the lungs, where its normal role is to protect them from the digestive effects of certain proteases. The unchecked activity of these proteases can cause auto-digestion of lung tissue and may lead to emphysema or chronic pulmonary obstructive disease, and lung infections over time. Currently, there is no cure or treatment that targets the underlying cause of the disease in both the liver and the lung. Available treatments are aimed at transiently increasing levels of AAT in the blood but have no effect.



in the liver. Patients living with AAT deficiency typically experience recurring hospital visits and a shortened life expectancy.

We seek to develop medicines that treat the underlying cause of AAT deficiency. In the laboratory, we have discovered multiple small molecule correctors that restore folding of the mutant AAT protein, with the potential to affect both the liver and lung diseases caused by AAT deficiency, and we are focused on identifying and developing multiple drug candidates with the potential to correct the misfolded protein. In 2020, we advanced two Phase 2 proof-of-concept clinical trials evaluating two investigational oral small molecule correctors, VX-814 and VX-864, for the treatment of people with AAT deficiency who have two copies of the Z mutation. In October 2020, we discontinued development of VX-814 based on the safety and pharmacokinetic profile observed in the clinical trial. Enrollment is ongoing in the clinical trial evaluating VX-864, and we expect data from this clinical trial in the first half of 2021. In addition, we continue to discover and develop additional molecules with the potential to correct AAT deficiency.

## APOL1-Mediated Kidney Diseases

Inherited mutations in the APOL1 gene play a causal role in the biology of FSGS as well as other kidney diseases. FSGS is a rare disease that attacks the kidney's filtering units, causing leakage of protein into the urine followed by deterioration in kidney function, scarring, and, ultimately, permanent kidney damage. FSGS is a leading cause of nephrotic syndrome in children and kidney failure in adults. We are evaluating multiple novel small molecules that inhibit the function of APOL1 protein with the potential to treat APOL1-mediated FSGS. In 2020, we initiated a Phase 2 proof-of-concept clinical trial for VX-147, our first investigational oral small molecule medicine for the treatment of FSGS and other serious kidney diseases. Enrollment is ongoing in this Phase 2 clinical trial and we expect data from the trial in 2021.

## Pain

Pain can develop from a variety of pathophysiological and psychological conditions. Patients with pain can suffer from acute pain (for example, following surgery or an injury), neuropathic pain (when there is damage to a nerve), and musculoskeletal pain. Current treatments may not work well and can cause significant side effects. In addition, there is the potential for addiction and the practice of over- and mis-utilization, as well as underutilization of current pain medicines.

Vertex has discovered multiple inhibitors of the voltage-gated sodium channel 1.8, or NaV1.8, as potential treatments for pain. Consistent with our research strategy, the Nav1.8 channel is a validated target for pain based both on inherited mutations that cause pain syndromes as well as our own clinical trial data. Specifically, we have obtained positive results from three separate Phase 2 clinical trials evaluating VX-150, a NaV1.8 inhibitor, in patients with three different pain conditions: acute post-surgical, chronic neuropathic and chronic musculoskeletal pain. We continue to focus our research and development efforts on discovering, developing and advancing a portfolio of multiple inhibitors of NaV1.8 as potential treatments for pain.

## Cell and Genetic Therapies

## Sickle Cell Disease and Beta Thalassemia

SCD and beta thalassemia are hemoglobinopathies, a group of inherited blood disorders that result from gene mutations that alter hemoglobin, a protein in red blood cells that delivers oxygen throughout the body.

SCD is caused by the change of a single amino acid in the hemoglobin gene that causes red cells to change shape in settings of low oxygen. These sickled cells block blood flow and can lead to severe pain, organ damage and shortened life span. Treatment is typically focused on relieving pain and minimizing organ damage, requiring medication and, for some patients, monthly blood transfusions and frequent hospital visits. We believe there are approximately 25,000 patients with severe SCD in the U.S. and E.U.

Beta thalassemia is caused by loss-of-function mutations in hemoglobin that lead to severe anemia in patients, which causes fatigue and shortness of breath. In infants, beta thalassemia causes failure to thrive, jaundice and feeding problems. Complications of beta thalassemia can lead to an enlarged spleen, liver and/or heart, misshapen bones and delayed puberty. Treatment for beta thalassemia varies depending on the disease severity for each patient. Patients with TDT, the most severe form of the disease, require regular blood transfusions, as frequently as every two to four weeks. Repeated blood transfusions eventually cause an unhealthy buildup of iron in the patient, leading to organ damage. We believe that there are approximately 7,000 patients with TDT in the U.S. and E.U.



In collaboration with CRISPR, we are co-developing CTX001, an investigational CRISPR/Cas9-based gene-editing therapy, for the treatment SCD and TDT. Our therapeutic approach involves isolating hematopoietic stem and progenitor cells, or HSPCs, which give rise to red blood cells, from a patient, treating those cells ex vivo with CRISPR/Cas9 in order to modify the erythroid-specific enhancer in the BCL11A gene, and reintroducing the edited cells back into the patient. This approach has the potential to increase levels of fetal hemoglobin in erythrocytes and reduce or eliminate symptoms associated with disease.

We and CRISPR are investigating CTX001 in two Phase 1/2 open-label clinical trials designed to assess the safety and efficacy of a single dose of CTX001 in patients ages 12 to 35 with TDT (CLIMB THAL-111) and severe SCD (CLIMB SCD-121), respectively. Patients enrolled in the clinical trial first undergo a treatment which mobilizes a population of HSPCs from the bone marrow into the bloodstream. Blood cells are collected from the patient's bloodstream and sent to a manufacturing facility where the HSPCs are purified and CRISPR/Cas9 gene-editing is performed. Following manufacturing, the edited cells, now called CTX001, are sent back to the clinical site. Patients are preconditioned with a treatment that ablates their bone marrow prior to infusion of CTX001.

In December 2020, we announced positive interim data from 10 people treated with CTX001 and that 20 people with severe hemoglobinopathies have been dosed with CTX001 in the ongoing Phase 1/2 clinical trials. All seven people with TDT were transfusion independent at last follow-up and all three people with SCD were free of vaso-occlusive crises from CTX001 infusion through the last follow-up. Enrollment and dosing are ongoing, and completion of enrollment for both clinical trials is expected in 2021.

## Type 1 Diabetes

T1D is a chronic, metabolic disorder caused by an absence of insulin secretion by the beta cells in the pancreas. In patients with T1D, the person’s own immune system attacks the insulin-producing islet cells of the pancreas, resulting in a complete lack of insulin. While insulin therapy allows patients to live for decades with the disease, challenges of insulin therapy include inadequate control of blood sugar (both hyper- and hypo-glycemia), burden of care on patients and families, and long-term vascular complications.

In 2019, we acquired Semma and established programs to develop cell-based therapies designed to replace insulin-producing islet cells in people with T1D. We are pursuing two programs for the transplant of functional islets into patients: transplantation of islet cells alone, using immunosuppression to protect the implanted cells, and implantation of the islet cells inside an immunoprotective device. The FDA has cleared our IND for VX-880, the first program (transplantation of islet cells alone), and we expect to initiate a Phase 1/2 clinical trial evaluating VX-880 in the first half of 2021. This clinical trial will involve an infusion of fully differentiated, functional islet cells, and chronic administration of concomitant immunosuppressive therapy, to protect the islet cells from immune rejection.

## Duchenne Muscular Dystrophy

DMD and DM1 are inherited diseases that result in the weakening and breakdown of skeletal muscles over time. In 2019, we acquired Exonics and expanded our collaboration with CRISPR establishing preclinical programs to develop gene-editing therapies for DMD and DM1. We are focused on advancing gene-editing therapies aimed at treating the underlying cause of DMD by restoring expression of near-full length dystrophin protein, and in DM1 by addressing the repeat expansion that causes the disease. Our collaboration with Affinia enables access to a novel library of AAV capsids to support our ongoing research and development efforts in genetic therapies, including DMD and DM1.

## COMMERCIALIZATION OF OUR MEDICINES

## Commercial Organization

Our commercial organization focuses on supporting sales of TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, ORKAMBI and KALYDECO in the markets where these products have been approved. Our sales and marketing organizations are responsible for promoting products to health care providers and obtaining reimbursement for our products from third-party payors, including governmental organizations in the U.S. and ex-U.S. markets.

Our U.S. field-based CF commercial team is comprised of a small number of individuals to support commercialization of our medicines for CF. We focus our CF marketing efforts in the U.S. on a relatively small number of physicians and health



care professionals who write most of the prescriptions for CF medicines. Many of these physicians and health care professionals are located at a limited number of accredited centers in the U.S. focused on the treatment of CF. In international markets, we have small sales forces that support KALYDECO, ORKAMBI, SYMDEKO/SYMKEVI and TRIKAFTA/KAFTRIO in jurisdictions where these products are approved.

We market our products through personal interactions with physicians and allied health care professionals. In addition, our government affairs and public policy group advocates for policies that promote life sciences innovation and increase awareness of the diseases on which we are focusing with state and federal legislatures, government agencies, public health officials and other policymakers. We also have established programs in the U.S. that provide our products to qualified uninsured or underinsured patients at no charge or at a reduced charge, based on specific eligibility criteria.

## Reimbursement

Sales of our products depend, to a large degree, on the extent to which our products will be reimbursed by third-party payors, such as government health programs, commercial insurance and managed health care organizations. Increasingly, these third-party payors are becoming stricter in the ways they evaluate medical products and services. Additionally, the containment of health care costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could limit our revenues. Decisions by third-party payors to not cover a product could reduce physician usage of the product.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, established the Medicare Part D program to provide a voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities, which provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutics committee. Government payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan likely will be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

The American Recovery and Reinvestment Act of 2009 provided funding for the federal government to compare the effectiveness of different treatments for the same illness. A plan for the research was to be developed by the Department of Health and Human Services, or HHS, the Agency for Healthcare Research and Quality and the National Institutes of Health, and periodic reports on the status of the research and related expenditures were to be made to the U.S. Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, it is not clear what effect, if any, the research will have on the sales of our products. In the future, it is possible that comparative effectiveness research demonstrating benefits of a competitor's product could adversely affect the sales of our products. If third-party payors do not consider our products to be cost-effective compared to other available therapies, they may not cover our products as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.

The Patient Protection and Affordable Care Act, or ACA, was enacted in March 2010 and was designed to expand coverage for the uninsured while at the same time containing overall health care costs. With regard to pharmaceutical products, among other things, the ACA was designed to expand and increase industry rebates for drugs covered under Medicaid programs, impose an annual fee on branded pharmaceutical manufacturers and make changes to the coverage requirements under the Medicare Part D program.

In Europe and other foreign jurisdictions, the success of our products depends largely on obtaining and maintaining government reimbursement because many patients are unable to access prescription pharmaceutical products that are not



reimbursed by their governments. Negotiating reimbursement agreements in foreign countries can delay the commercialization of a pharmaceutical product and can result in a reimbursement price that is lower than the net price that companies can obtain for the product in the U.S.

In some countries, such as Germany, commercial sales of a new product may begin while the reimbursement rate that a company will receive is under discussion. In other countries, a company must complete reimbursement negotiations prior to the commencement of commercial supply of the pharmaceutical product. The requirements governing drug pricing vary widely from country to country. For example, the member states of the E.U. can restrict the range of drugs for which their national health insurance systems provide reimbursement and can control the prices of prescription drugs. In addition, many ex-U.S. government payers require companies to provide health economic assessments of products, which are evaluated by government agencies set up for this purpose. A member state may approve a specific price for the drug or it may instead adopt a system of direct or indirect controls on the total amount of money that a company may receive for supply of a drug. Countries also may consider increasing mandatory discounts in an attempt to manage increased demands on healthcare budgets. Reimbursement for our products cannot be assured. In addition, it is possible that a country may only provide for reimbursement on terms that we do not deem adequate. Additionally, reimbursement discussions in ex-U.S. markets may take a significant period of time.

## STRATEGIC TRANSACTIONS AND COLLABORATIONS

As part of our business strategy, we seek to license or acquire drugs, drug candidates, businesses and other technologies that have the potential to complement our ongoing research and development efforts. In addition, we establish business relationships with collaborators to support our research activities and to lead or support development and/or commercialization of certain drug candidates. We expect to continue to identify and evaluate potential acquisitions, licenses and collaborations that may be similar or different from the transactions that we have engaged in previously.

## Strategic Transactions

## Acquisitions

In 2019, we acquired Semma, a privately-held company focused on the use of stem cell-derived human islets as a potentially curative treatment for T1D. Our acquisition of Semma advanced our cell therapy capabilities and supports the development of transformative therapies for T1D. In connection with the acquisition, we acquired all of the outstanding equity of Semma for approximately $950.0 million in cash.

In 2019, we acquired Exonics, a privately held company focused on creating transformative gene-editing therapies to repair mutations that cause DMD and other severe neuromuscular diseases, including DM1. Our acquisition of Exonics enhanced our gene-editing capabilities and supports the potential development of novel therapies for DMD and DM1. In connection with the acquisition, we acquired all of the outstanding equity of Exonics for an upfront payment of approximately $245.0 million plus customary working capital adjustments in cash, and certain potential future payments based primarily upon the successful achievement of specified development and regulatory milestones for the DMD and DM1 programs.

## Collaboration and Licensing Arrangements

## Joint Development and Commercialization Agreement with CRISPR

In December 2017, we entered into a joint development and commercialization agreement, or JDA, with CRISPR pursuant to which we are co-developing and preparing to co-commercialize CTX001 for TDT and SCD. This JDA was entered into following our exercise of an option to co-develop and co-commercialize the hemoglobinopathies program that was contained in the collaboration agreement that we entered into with CRISPR in 2015. The net profits and net losses, as applicable, incurred under the JDA will be shared equally by the parties. Under the JDA, CRISPR will be responsible for commercialization activities in the U.S. and we will be responsible for commercialization activities outside of the U.S. There is a joint committee to provide high-level oversight and decision-making regarding the activities covered by the JDA. The committee contains an equal number of representatives from us and CRISPR.

Either party can terminate the JDA upon the other party’s material breach, subject to specified notice and cure provisions, or, in our case, in the event that CRISPR becomes subject to specified bankruptcy, winding up or similar



circumstances. Either party may terminate the JDA in the event the other party commences or participates in any action or proceeding challenging the validity or enforceability of any patent that is licensed to such challenging party pursuant to the JDA. We also have the right to terminate the JDA for convenience at any time after giving prior written notice. If circumstances arise pursuant to which a party would have the right to terminate the JDA on account of an uncured material breach, such party may elect to keep the JDA in effect and cause such breaching party to be treated as if it had exercised its opt-out rights with respect to the products associated with such uncured material breach and the royalties payable to the breaching party would be reduced by a specified percentage.

Either party may opt of out of the development of a product candidate under the JDA after predetermined points in the development of the product candidate, on a candidate-by-candidate basis. In the event of such opt-out, the party opting-out will no longer share in the net profits and net losses associated with such product candidate and, instead, the opting out party will be entitled to high single to mid-teen percentage royalties on the net sales of such product, if commercialized.

## In-License Agreements

We have entered into various agreements pursuant to which we have obtained access to technologies from third parties and are conducting research and development activities with collaborators. Pursuant to these arrangements, we have obtained development and commercialization rights to resulting drug candidates. Depending on the terms of the arrangements, we may be responsible for the costs of research activities, required to make upfront payments and/or milestone payments upon the achievement of certain research and development objectives, and/or pay royalties on future sales, if any, of commercial products resulting from the collaboration. Our current in-license agreements include:

• Affinia Therapeutics, Inc. In 2020, we entered into a collaboration with Affinia to gain access to a novel library of AAV capsids to support on our ongoing research and development efforts in genetic therapies, including DMD, DM1 and CF.

• Arbor Biotechnologies, Inc. In 2018, we entered into a collaboration with Arbor Biotechnologies, pursuant to which we are focusing on the discovery of novel proteins, including DNA endonucleases, to advance the development of new gene-editing therapies.

- CRISPR Therapeutics AG. In 2015, we entered into a collaboration with CRISPR for the discovery and development of potential new treatments aimed at the underlying genetic causes of human diseases using CRISPR-Cas9 gene-editing technology. As described above, we currently are co-developing CTX001 for the treatment of SCD and beta thalassemia and, if successful, have agreed to co-commercialize CTX001. In addition, we have exercised options to exclusively license treatments for specific targets, including CF, that were subject to the research program. In 2019, we obtained exclusive worldwide rights to CRISPR's intellectual property for DMD and DM1 gene-editing products through a new agreement with CRISPR.

• Kymera Therapeutics, Inc. In 2019, we entered into a collaboration with Kymera Therapeutics for the research and development of small molecule protein degraders. Under the collaboration, Kymera Therapeutics conducts research activities in multiple targets, and upon designation of a clinical development candidate for a target, we have the option to exclusively license molecules against the target.

• Moderna, Inc. In 2016, we entered into a collaboration with Moderna, pursuant to which we are seeking to identify and develop mRNA therapeutics for the treatment of CF. In 2020, we entered into a new strategic collaboration with Moderna aimed at the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies to lung cells for the treatment of CF.

• Skyhawk Therapeutics, Inc. In December 2020, we entered into a collaboration with Skyhawk Therapeutics, for the discovery and development of novel small molecules that modulate RNA splicing for the treatment of serious diseases.

• Other Arrangements. In 2019, we entered into collaborations with Molecular Templates, Inc. and Ribometrix, Inc. In 2018, we entered into agreements with Genomics plc, Merck KGaA, Darmstadt, Germany, and X-Chem, Inc. in order to support our research and development efforts.



## Out-license Agreements

We have entered into various agreements pursuant to which we have out-licensed rights to certain drug candidates to third-party collaborators. Pursuant to these out-license arrangements, our collaborators are responsible for all costs related to the continued development of such drug candidates and obtain development and commercialization rights to these drug candidates. Depending on the terms of the arrangements, our collaborators may be required to make upfront payments, milestone payments upon the achievement of certain research and development objectives and/or pay royalties on future sales, if any, of commercial products licensed under the agreement. Our current out-license agreements include a Strategic Collaboration and License Agreement with Merck KGaA, Darmstadt, Germany, that we entered into in 2017, pursuant to which we granted an exclusive worldwide license to research, develop and commercialize four oncology research and development programs.

## Cystic Fibrosis Foundation Therapeutics Incorporated

In 2004, we entered into a collaboration agreement with the Cystic Fibrosis Foundation, or CFF, as successor in interest to the Cystic Fibrosis Foundation Therapeutics, Inc., to support research and development activities. Pursuant to the collaboration agreement, as amended, we have agreed to pay tiered royalties ranging from single digits to sub-teens on covered compounds first synthesized and/or tested during a research term on or before February 28, 2014, including KALYDECO (ivacaftor), ORKAMBI (lumacaftor in combination with ivacaftor) and SYMDEKO/SYMKEVI (tezacaftor in combination with ivacaftor) and royalties ranging from low-single digits to mid-single digits on potential net sales of certain compounds first synthesized and/or tested between March 1, 2014 and August 31, 2016, including lexacaftor. For combination products, such as ORKAMBI, SYMDEKO/SYMKEVI and TRIKAFTA/KAFTRIO (lexacaftor, tezacaftor, and ivacaftor), sales are allocated equally to each of the active pharmaceutical ingredients in the combination product.

## INTELLECTUAL PROPERTY

Patents and other proprietary rights such as trademarks, trade secrets, and copyrights are critical to our business. We actively seek protection for our products and proprietary information by means of U.S. and foreign patents, trademarks and copyrights, as appropriate. In addition, we rely upon trade secret protection and contractual arrangements to protect certain of our proprietary information and products.

Patents provide a period of exclusivity that can make it more difficult for competitors to market and use our technology. We own patents and pending patent applications that relate to compounds, formulations, treatment of diseases, synthetic routes, intermediates and other inventions.

To protect our intellectual property, we typically apply for patents several years before a product receives marketing approval. Under current law, a patent expires 20 years from its first effective filing date. Since the drug development process may last for many years, there may be a period of time in which we have an issued patent but not marketing approval to sell the drug. To compensate for patent term lost while a product is in clinical trials and undergoing review for marketing approval, we may be able to apply for patent term extensions or supplementary protection certificates in some countries. In addition to patent protection, we have regulatory exclusivity from U.S. and European regulatory agencies for the active pharmaceutical agents and, where applicable, their approved orphan indications for a certain time period. Regulatory exclusivity runs concurrently with patent exclusivity and provides complementary protection.

We own or hold exclusive licenses to several hundred patents in the U.S. Upon approval of an NDA or a supplement thereto, NDA sponsors are required to list with the FDA each patent with claims that cover the applicant's product or a method of using the product. Each of the patents listed by the NDA sponsor is published in the FDA's Orange Book. We have ten issued U.S. patents listed in the Orange Book that cover the active pharmaceutical ingredients in KALYDECO, its marketed formulations, and/or its approved indication. We have 19 issued U.S. patents listed in the Orange Book that cover the active pharmaceutical ingredients in ORKAMBI, its marketed formulations, and/or its approved indication. We have 21 issued U.S. patents listed in the Orange Book that cover the active pharmaceutical ingredients in SYMDEKO, its marketed formulation, and/or its approved indication. We have 21 issued U.S. patents listed in the Orange Book that cover the active pharmaceutical ingredients in TRIKAFTA, its marketed formulation, and/or its approved indication.

The table below sets forth the year of projected expiration for the basic product patents covering each of our approved products. For products that are combinations of two or more active ingredients, the table lists the projected expiration of the



latest expiring patent covering any of the active pharmaceutical ingredients (lunacaftor for ORKAMBI, tezacaftor for SYMDEKO/SYMKEVI and lexacaftor for TRIKAFTA/KAFTRIO). Patent term extensions, supplementary protection certificates, and pediatric exclusivity periods are not reflected in the expiration dates listed in the table below and may extend protection. In some instances, we also own later-expiring patents and applications relating to solid forms, formulations, methods of manufacture, or the use of these drugs in the treatment of particular diseases or conditions. In some cases, however, such patents may not protect our drug from generic competition after the expiration of the basic patent.

<table><tr><td>Product</td><td>Projected Expiration of U.S. Patent</td><td>Projected Status of European Patent</td></tr><tr><td>KALYDECO</td><td>2027</td><td>2025 1</td></tr><tr><td>ORKAMBI</td><td>2030</td><td>2026 2</td></tr><tr><td>SYMDEKO/SYMKEVI</td><td>2027</td><td>2028 3</td></tr><tr><td>TRIKAFTA/KAFTRIO</td><td>2037</td><td>2037</td></tr></table>

 \( ^{1} \)  Certain European countries have granted supplementary protection certificates for KALYDECO, which expire in 2027.

 \( ^{2} \)  Certain European countries have granted supplementary protection certificates for ORKAMBI, which expire in 2030.

 \( ^{3} \)  Certain European countries have granted supplementary protection certificates for SYMKEVI, which expire in 2033.

In addition to protecting our marketed products, we actively monitor and file patent applications in the U.S. and in foreign countries on inventions relating to our pipeline. For example, we also own U.S. and foreign patents and/or we have patent applications relating to the following:

• CTX001 and other potential gene-editing approaches for treating hemoglobinopathies.

• VX-864 and other compounds being studied for the potential treatment of AAT deficiency.

• VX-147 and other compounds being studied for the potential treatment of APOL1-mediated kidney diseases.

• CF potentiators and correctors and many other related compounds, and the use of those compounds to treat CF.

• Other pre-clinical and clinical candidates and the use of such candidates to treat specified diseases.

- The manufacture, pharmaceutical compositions, related solid forms, formulations, dosing regimens and methods of use of many of the above compounds.

We and CRISPR intend to rely upon a combination of rights, including patent rights, trade secret protection, and regulatory exclusivities to protect CTX001. CRISPR has licensed certain rights to a worldwide patent portfolio that covers various aspects of the CRISPR/Cas9 editing platform technology including, for example, compositions of matter and methods of use, including their use in targeting or cutting DNA from Dr. Charpentier. In addition to Dr. Charpentier, this patent portfolio has named inventors who assigned their rights to the Regents of the University of California or the University of Vienna, to whom we refer, together with Dr. Charpentier, as the CVC Group. CRISPR has non-exclusive or co-exclusive rights to the patent rights that protect the core CRISPR/Cas9 gene-editing technology. For example, certain third parties, including competitors, have reported obtaining a license to rights in this patent portfolio in certain fields. In addition, patents and patent applications in this patent portfolio are the subject of proceedings in the U.S., Europe, and other jurisdictions, including proceedings between the CVC and the Broad Institute in the U.S. Patent and Trademark Office, or USPTO. To date, both the CVC and the Broad have obtained granted patents that purport to cover aspects of CRISPR/Cas9 editing platform technology. The patents and patent applications within the CVC patent portfolio and the Broad patent portfolio are, or may in the future be, involved in proceedings similar to interferences or priority disputes in Europe or other foreign jurisdictions. In addition to the patent portfolio licensed from Dr. Charpentier, we own patent applications relating to the composition, manufacture, and use of CTX001.

From time to time we enter into exclusive and non-exclusive license agreements for proprietary third-party technology used in connection with our research activities. These license agreements typically provide for the payment by us of a license fee but may also include terms providing for milestone payments or royalties for the development and/or commercialization of our drug products arising from the related research.

We cannot be certain that issued patents we own or license will be enforceable or provide adequate protection or that pending patent applications will result in issued patents. The existence of patents does not guarantee our right to practice the patented technology or commercialize the patented product. Litigation, interferences, oppositions, inter partes reviews,



administrative challenges or other similar types of proceedings may be necessary in some instances to determine the validity and scope of certain patents, regulatory exclusivities or other proprietary rights, and in other instances to determine the validity, scope or non-infringement of intellectual property rights that may be claimed by third parties to be pertinent to the manufacture, use or sale of our products.

## MANUFACTURING

As we market and sell our approved products and advance our drug candidates through clinical development toward commercialization, we continue to build and maintain our supply chain and quality assurance resources. We rely on internal capabilities and a global network of third parties to manufacture and distribute our products for commercial sale and post-approval clinical trials and to manufacture and distribute our drug candidates for clinical trials. In addition to establishing supply chains for each new approved product, we need to adapt our supply chain for existing products to include additional formulations that are often required in order to treat younger patients or to increase scale of production for existing products. We are focused on ensuring the stability of the supply chains for our current products, including TRIKAFTA/KAFTRIO, and for our pipeline programs. In addition, we are focused on identifying and ensuring the optimal manufacturing and delivery requirements for the cell and genetic therapies we are developing.

We expect that we will continue to rely on third parties to meet our commercial supply needs and a significant portion of our clinical supply needs for the foreseeable future. We have established our own small-scale manufacturing capabilities in Boston, which we use for clinical trial and commercial supplies, and are evaluating additional manufacturing capacity for our current and future products.

Our supply chain for sourcing raw materials and manufacturing drug product ready for distribution is a multi-step global endeavor. In general, these raw materials are available from multiple sources. Third-party contract manufacturers, including some in China, perform different parts of our manufacturing process. Contract manufacturers may supply us with raw materials, convert these raw materials into drug substance and/or convert the drug substance into final dosage form. In addition, third parties assist us with packaging, warehousing and distribution of products.

Establishing and managing this global supply chain for each of our drugs and drug candidates requires a significant financial commitment and the creation and maintenance of numerous third-party contractual relationships. To ensure the stability of our supply chains, we aim to develop alternatives for each step of our manufacturing process at the time of, or shortly after, marketing approval. Therefore, at any point in time, we may have a limited number of single source manufacturers for certain steps in our manufacturing processes, particularly for recently launched products.

In order to manufacture our commercial products, we utilize both continuous manufacturing technology as well as batch manufacturing processes. While continuous process manufacturing has been used in many industries, we believe that we are the first company to obtain FDA approval for a fully-continuous drug product manufacturing process.

We have developed systems and processes to track, monitor and oversee our third-party manufacturers' activities, including a quality assurance program intended to ensure that our third-party manufacturers comply with current Good Manufacturing Practices, or cGMP. We regularly evaluate the performance of our third-party manufacturers with the objective of confirming their continuing capabilities to meet our needs efficiently and economically. Manufacturing facilities, both foreign and domestic, are subject to inspections by or under the authority of the FDA and other U.S. and foreign government authorities.

The manufacturing processes for cell and genetic therapies are more complex than those required for small molecule drugs and require different systems, equipment, facilities and expertise. Additionally, we are unable to rely on a single process for all of our cell and genetic therapies; they must be customized for each program and therapy. Although we have been building expertise in these areas, which was augmented through our acquisitions of Exonics and Semma, we will need to continue to expand and strengthen our manufacturing infrastructure and capabilities, independently and/or through a third-party network, to successfully develop and commercialize cell and genetic therapies. We are focused on evaluating and securing potential relationships with various third parties that would enable us to expand and strengthen such capabilities to support our current and future cell and genetic therapy programs. We expect to make significant investment in our manufacturing capabilities and partnerships for our genetic and cell-based therapy programs in order to continue to advance and, in the future, commercialize these programs.



We and CRISPR rely on third-party manufacturers to produce or process cell culture reagents, gene-editing components, such as Cas9 protein and guide RNA molecules, and to generate gene-edited cells to supply CTX001 for clinical trials. If approved, we expect to continue to rely on third-party manufacturers for commercial supply of CTX001. The current manufacturing process for CTX001 involves a number of steps prior to the final infusion of drug product into patients. Following mobilization and collection of blood cells from the patient at the clinical site, cells are transferred to a manufacturing site where HSPCs are purified and CRISPR/Cas9 gene-editing is performed. The edited cellular product, called CTX001, is frozen and transported back to the clinical site where it is stored prior to infusion into the patient. Each step must be completed successfully, and in a timely manner, requiring coordination between CRISPR, Vertex, clinical sites, third-party manufacturers and shipping vendors. To increase production to commercial levels, Vertex and CRISPR will need to coordinate manufacturing and logistics activities at a larger scale across multiple facilities in the geographies in which CTX001 is approved. Approval will rely on inspection and approval of these facilities by global health authorities.

## COMPETITION

The pharmaceutical industry is characterized by extensive research efforts, rapid technological progress and intense competition. There are many public and private companies, including pharmaceutical companies and biotechnology companies, engaged in developing products for the indications our drugs are approved to treat and the therapeutic areas we are targeting with our research and development activities. Potential competitors also include academic institutions, government agencies, other public and private research organizations and charitable venture philanthropy organizations that conduct research, seek patent protection and/or establish collaborative arrangements for research, development, manufacturing and commercialization. Mergers and acquisitions in the pharmaceutical, biotechnology and gene therapy industries may result in a larger concentration of resources among a smaller number of our competitors. Some of our competitors may have substantially greater financial, technical, marketing and human resources than we do.

We believe that competition in our industry is based on, among other factors, innovative research, the effective and rapid development of drug candidates, the ability to market and obtain reimbursement for products and the ability to establish effective patent protection. We face competition based on the safety and efficacy of our product and drug candidates, the timing and scope of regulatory approvals, the availability and cost of supply, marketing and sales capabilities, reimbursement coverage, price, patent protection and other factors. Our competitors may develop or commercialize more effective, safer or more affordable products than we are able to develop or commercialize or obtain more effective patent protection. As a result, our competitors may commercialize products more rapidly or effectively than we do, which would adversely affect our competitive position, the likelihood that our drug candidates, if approved, would achieve and maintain market acceptance and our ability to generate meaningful revenues from our products. Future competitive products may render our products, or future products, obsolete or noncompetitive. Another key element of remaining competitive in our industry is recruiting and retaining leading scientific, technical and management personnel to conduct our research activities and advance our development programs, including with the commercial expertise to effectively market our products.

## Cystic Fibrosis

A number of companies are seeking to identify and develop drug candidates for the treatment of CF, including CFTR modulators and other therapies intended to address the underlying causes of CF.

AbbVie, Inc., or AbbVie, has indicated that it plans to develop a triple combination CFTR modulator therapy comprised of a potentiator and correctors. Currently, AbbVie is evaluating the combination of a potentiator and a corrector in a Phase 2 clinical trial. In March 2020, AbbVie disclosed plans to file an IND application with the FDA for another corrector in the second quarter of 2020. In addition, Proteostasis Therapeutics, Inc. was developing potential CFTR modulator therapies prior to its acquisition by Yumanity Therapeutics, Inc., or Yumanity. Following the merger, Yumanity has announced plans to divest its CF program.

Other therapeutic approaches include addressing CF utilizing nucleic acid therapies and read-through agents, which are compounds that allow expression of a full-length protein. Nucleic acid therapies are under development by companies such as Translatie Bio, Arcturus Therapeutics Holdings, Inc., Krystal Biotech, Inc., Spirovant Sciences, Inc. and 4D Molecular Therapeutics, Inc. Translatie Bio is evaluating its mRNA therapy in a proof of concept Phase 1/2 clinical trial. Eloxx Pharmaceuticals, Inc. is evaluating a read-through therapy for nonsense CFTR mutations in two Phase 2 clinical trials.



Our success in rapidly developing and commercializing our products may increase the resources that our competitors allocate to the development of these potential treatments for CF. If one or more competing therapies are successfully developed as a treatment for people with CF, our revenues from our current products and/or additional CF products, if then approved, could face significant competitive pressure.

## Pipeline

In recent years, we have committed significant research resources to, and made significant investments in, our pipeline of potential new therapies for AAT deficiency, APOL1-mediated kidney diseases, TDT, SCD, muscular dystrophies, T1D and other diseases. We plan to continue investing in our pipeline, including expanding beyond small molecule therapies and into the discovery and development of cell and gene therapies. For example, we remain focused on our ongoing evaluation of CTX001, an investigational CRISPR/Cas9-based gene-editing therapy, for treatment of SCD and TDT currently in clinical development.

There are multiple approved treatments for TDT and SCD, including products from Novartis International AG, or Novartis, Global Blood Therapeutics, Inc. and Bristol Myers Squibb together with Acceleron Pharma, Inc. Bluebird Bio, Inc., or Bluebird, has a gene therapy, Zynteglo (Lentiglobin), approved by the European Medicines Agency, or EMA, for the treatment of certain TDT genotypes and in clinical development for SCD. In addition, various companies and private academic/medical institutes are developing gene therapy or gene-editing candidates for the treatment of SCD or TDT utilizing CRISPR technology, lentiviral vectors, zinc finger nuclease technology, or base editing.

Many other pharmaceutical and biotechnology companies are also investing resources for discovery and development of small molecules, gene therapies and cell therapies to treat the same diseases for which we are developing therapies. If any of these competitors develop or successfully commercialize products involving therapies competitive with our pipeline therapies, the potential return on our investment in those pipeline therapies could be impacted.

## GOVERNMENT REGULATION

Our operations and activities are subject to extensive regulation by numerous government authorities in the U.S., the E.U. and other countries. In the U.S., the E.U. and other countries, drugs are subject to rigorous regulations governing the testing, manufacture, labeling, storage, record keeping, approval, advertising and promotion of our products. As a result of these regulations, product development and product approval processes are very expensive and time consuming. The regulatory requirements applicable to drug development, approval, and marketing are subject to change. In addition, regulations and administrative guidance often are revised or reinterpreted by the agencies in ways that may significantly affect our business and our products. It is impossible to predict whether legislative changes will be enacted, or FDA or comparable ex-U.S. regulations, guidance or interpretations will change.

## United States Government Regulation

## New Drug Application Approval Processes

The process required by the FDA before a drug may be marketed in the U.S. generally involves the following:

• completion of preclinical laboratory tests, animal studies and formulation studies conducted according to Good Laboratory Practices, or GLP, and other applicable regulations;

• submission to the FDA of an IND application, which must become effective before clinical trials in the U.S. may begin;

• performance of adequate and well-controlled clinical trials according to Good Clinical Practices, or GCP, to establish the safety and efficacy of the proposed drug for its intended use;

• submission to the FDA of a New Drug Application, or an NDA;

• satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product will be produced to assess compliance with cGMP; and

• FDA review and approval of the NDA.



Once a drug candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal pharmacology and toxicology studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information and analytical data, to the FDA as part of the IND, which seeks FDA approval to test the drug candidate in humans. Preclinical or nonclinical testing typically continues even after the IND is submitted.

If the FDA accepts the IND, the drug candidate can then be studied in human clinical trials to determine if the drug candidate is safe and effective. These clinical trials involve three separate phases that often overlap, can take many years and are expensive. These three phases, which are subject to considerable regulation, are as follows:

- Phase 1. The drug initially is introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and elimination. In the case of some drug candidates for severe or life-threatening diseases, such as cancer, especially when the drug candidate may be inherently too toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

- Phase 2. Clinical trials are initiated in a limited patient population intended to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the drug candidate for specific targeted diseases and to determine dosage tolerance and optimal dosage.

- Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk-benefit ratio of the drug candidate and provide an adequate basis for regulatory approval and product labeling.

Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within any specified period, if at all. The FDA or the sponsor may suspend a clinical trial at any time for a variety of reasons, including a finding that the healthy volunteers or patients are being exposed to an unacceptable health risk. All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP. Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently in other situations, including the occurrence of serious adverse events. Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health for public dissemination on the www.clinicaltrials.gov website.

The results of drug development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the drug candidate, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the drug candidate. The FDA reviews each NDA submitted to ensure that it is sufficiently complete for substantive review before it accepts it for filing. It may request additional information rather than accept an NDA for filing.

Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA reviews an NDA to determine, among other things, whether a drug candidate is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the drug candidate's identity, strength, quality and purity. The FDA may refer the NDA to an advisory committee for review and recommendation as to whether the NDA should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA, the FDA will inspect the facility or facilities where the drug candidate is manufactured and tested. Additionally, before approving an NDA, the FDA may inspect one or more clinical trial sites to assure compliance with GCP requirements.

The FDA may require, as a condition of approval, restricted distribution and use, enhanced labeling, special packaging or labeling, expedited reporting of certain adverse events, pre-approval of promotional materials, restrictions on direct-to-consumer advertising or commitments to conduct additional research post-approval. The FDA will issue a complete response letter if the agency decides not to approve the NDA in its present form.

## Biologics License Application Process

Certain of our drug candidates may be regulated by the FDA under the Food, Drug, and Cosmetic Act, or FDCA, and the Public Health Service Act as biologics. Biologics can present special safety, efficacy and manufacturing challenges that may differ from those present in the regulation of small molecule drugs. As such, while similar to the NDA review process described above, in lieu of filing an NDA, biologics require the submission of a Biologics License Application, or BLA, and approval of such BLA by the FDA prior to being marketed in the U.S.



## Expedited Review and Approval

The FDA has developed a number of distinct approaches to make new drugs available as rapidly as possible in cases where there is no available treatment or there are advantages over existing treatments.

The FDA may grant “accelerated approval” to products that have been studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit to patients over existing treatments. For accelerated approval, the product must have an effect on a surrogate endpoint or an intermediate clinical endpoint that is considered reasonably likely to predict the clinical benefit of a drug, such as an effect on irreversible morbidity and mortality. When approval is based on surrogate endpoints or clinical endpoints other than survival or morbidity, the sponsor will be required to conduct additional post-approval clinical studies to verify and describe the clinical benefit. These studies are known as “confirmatory trials.” Approval of a drug may be withdrawn, or the labeled indication of the drug changed if these trials fail to verify clinical benefit or do not demonstrate sufficient clinical benefit to justify the risks associated with the drug.

The FDA may grant “fast track” status to products that treat serious diseases or conditions and demonstrate the potential to address an unmet medical need. Fast track is a process designed to facilitate the development and expedite the review of such products by providing, among other things, more frequent meetings with the FDA to discuss the product’s development plan and rolling review, which allows submission of individually completed sections of an NDA or BLA for FDA review before the entire submission is completed. Fast track status does not ensure that a product will be developed more quickly or receive FDA approval.

“Breakthrough Therapy” designation is a process designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint. For drugs and biologics that have been designated as Breakthrough Therapies, robust FDA-sponsor interaction and communication can help to identify the most efficient and expeditious path for clinical development while minimizing the number of patients placed in ineffective control regimens.

“Regenerative Medicine Advanced Therapy,” or RMAT, designation is a process created by the 21st Century Cures Act in December 2016. A product is eligible for RMAT designation if it is a regenerative medicine therapy that is intended to treat, modify, reverse or cure a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the product has the potential to address unmet medical needs for such disease or condition. The benefits of RMAT designation include the benefits available to breakthrough therapies, including potential eligibility for priority review and accelerated approval based on surrogate or intermediate endpoints.

The FDA may grant “priority review” status to products that, if approved, would provide significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions. Priority review is intended to reduce the time it takes for the FDA to review an NDA or BLA, with the goal to take action on the application within six months from when the application is filed, compared to ten months for a standard review.

## Manufacturing Quality Control

Among the conditions for NDA or BLA approval is the requirement that the prospective manufacturer’s quality control and manufacturing procedures continually conform with cGMP. In complying with cGMP, manufacturers must devote substantial time, money and effort in the areas of production, quality control and quality assurance to maintain compliance. Material changes in manufacturing equipment, location or process, may result in additional regulatory review and approval. The FDA, and other regulatory agencies, conduct periodic visits to inspect equipment, facilities, and processes following the initial approval of a product. If a manufacturing facility is not in substantial compliance with the applicable regulations and requirements imposed when the product was approved, regulatory enforcement action may be taken, which may include a warning letter or an injunction against shipment of products from the facility and/or recall of products previously shipped. We rely, and expect to continue to rely, on third parties for the production of our products. Future FDA, state, and foreign inspections may identify compliance issues at the facilities of our contract manufacturers that may disrupt manufacture or distribution of our products or require substantial resources to correct.



## Post-approval Requirements

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or complete withdrawal of the product from the market. In addition, under the FDCA the sponsor of an approved drug in the U.S. may not promote that drug for unapproved, or off-label, uses, although a physician may prescribe a drug for an off-label use in accordance with the practice of medicine. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval. In addition, the FDA may require testing and surveillance programs to monitor the effect of approved products that have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs.

Products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things:

• record-keeping requirements;

• reporting of adverse experiences with the product;

• providing the FDA with updated safety and efficacy information;

• drug sampling and distribution requirements;

• notifying the FDA and gaining its approval of specified manufacturing or labeling changes;

• complying with certain electronic records and signature requirements; and

• complying with FDA promotion and advertising requirements.

Failure to comply with the applicable U.S. requirements at any time during the drug development process, approval process or after approval, may subject us or our collaborators to administrative or judicial sanctions, any of which could have a material adverse effect on us. These sanctions could include:

• refusal to approve or delay in review of pending applications;

• withdrawal of an approval or the implementation of limitations on a previously approved indication for use;

• imposition of a clinical hold, a risk mitigation and evaluation strategy or other safety-related limitations;

• warning letters or “untitled letters”;

• product seizures;

• total or partial suspension of production or distribution; or

• injunctions, fines, disgorgement, refusals of government contracts, or civil or criminal penalties.

## Patent Term Restoration and Regulatory Exclusivity

Upon approval, products may be entitled to certain kinds of exclusivity under applicable intellectual property and regulatory regimes. The Drug Price Competition and Patent Term Restoration Act of 1984 (commonly known as the Hatch-Waxman Act) permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. The length of the patent extension is roughly based on 50 percent of the period of time from the filing of an IND for a compound to the submission of the NDA for such compound, plus 100 percent of the time period from NDA submission to regulatory approval. The extension, however, cannot exceed five years and the patent term remaining after regulatory approval cannot exceed 14 years.

If the FDA approves a drug product that contains an active ingredient not previously approved, the product is typically entitled to five years of non-patent regulatory exclusivity. Other products may be entitled to three years of exclusivity if approval was based on the FDA’s reliance on new clinical studies essential to approval submitted by the NDA applicant. If



the NDA applicant studies the product for use by children, the FDA may grant pediatric exclusivity, which extends by 180 days each existing exclusivity (patent and regulatory) related to the product.

Biologics are also entitled to exclusivity under the Biologics Price Competition and Innovation Act, which was passed as Title VII to the ACA. The law provides a pathway for approval of biosimilars following the expiration of 12 years of exclusivity for the innovator biologic and a potential additional 180 day-extension term for conducting pediatric studies. Biologics are also eligible for orphan drug exclusivity, as discussed below. The law also includes an extensive process for the innovator biologic and biosimilar manufacturer to litigate patent infringement, validity, and enforceability prior to the approval of the biosimilar. There have been ongoing federal legislative and administrative efforts as well as judicial challenges seeking to repeal, modify or invalidate some or all of the provisions of the ACA. While none of those efforts have focused on changes to the provisions of the ACA related to the biosimilar regulatory framework, if the ACA is repealed, substantially modified, or invalidated, it is unclear what, if any, impact such action would have on biosimilar regulation.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drug candidates intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 people in the U.S.

If a drug candidate that has orphan drug designation subsequently receives the first FDA approval for that drug for the disease for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication for seven years following marketing approval, except in certain very limited circumstances, such as if the later product is shown to be clinically superior to the orphan product. Orphan drug exclusivity, however, also could block the approval of our drug candidates for seven years if a competitor first obtains approval of the same product as defined by the FDA or if our drug candidate is determined to be contained within the competitor's product for the same indication or disease. KALYDECO, ORKAMBI, SYMDEO, and TRIKAFTA have been granted orphan drug exclusivity by the FDA.

## Foreign Regulation

We conduct clinical trials and market our products in numerous jurisdictions outside the U.S. Most of these jurisdictions have clinical trial, product approval and post-approval regulatory processes that are similar in principle to those in the U.S. Thus, whether or not we obtain FDA approval for a drug candidate, we must obtain approval by the comparable regulatory authorities of foreign countries or economic areas, such as the E.U., before we can commence clinical trials or market products in those countries or areas. The approval process and requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from place to place, and the time may be longer or shorter than that required for FDA approval.

Under E.U. regulatory systems, a company may submit marketing authorization applications either under a centralized or decentralized procedure. The centralized procedure, which is compulsory for medicines produced by biotechnology or those medicines intended to treat AIDS, cancer, neurodegenerative disorders, or diabetes and optional for those medicines that are highly innovative, provides for the grant of a single marketing authorization that is valid for all E.U. member states. In addition to the centralized procedure, Europe also has a nationalized procedure, which requires a separate application to and approval determination by each country; a decentralized procedure, whereby applicants submit identical applications to several countries and receive simultaneous approval; and a mutual recognition procedure, where applicants submit an application to one country for review and other countries may accept or reject the initial decision.

## Other Regulations

Pharmaceutical companies are also subject to various laws pertaining to healthcare “fraud and abuse,” including anti-kickback and false claims laws. Anti-kickback laws generally make it illegal to knowingly and willfully solicit, offer, receive or pay any remuneration in return for or to induce the referral of business, including the purchase or prescription of a particular drug that is reimbursed by a state or federal health care program. False claims laws prohibit knowingly and willingly presenting, or causing to be presented for payment to third-party payors (including Medicare and Medicaid), any claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed or claims for medically unnecessary items or services. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as by the possibility of exclusion from federal healthcare programs (including Medicare and Medicaid). Liability under the false claims laws may also arise when a violation of certain laws or regulations related to the underlying products (e.g., violations regarding improper promotional activity or unlawful



payments) contributes to the submission of a false claim. If we were subject to allegations concerning, or convicted of violating, these laws, our business could be harmed.

Laws and regulations also have been enacted by the federal government and various states to regulate the sales and marketing practices of pharmaceutical manufacturers. The laws and regulations generally limit financial interactions between manufacturers and health care providers, require manufacturers to adopt certain compliance standards or require disclosure to the government and public of such interactions. The laws include U.S. federal and state “sunshine” provisions. The federal sunshine provisions apply to pharmaceutical manufacturers with products reimbursed under certain government programs and require those manufacturers to disclose annually to the federal government (for re-disclosure to the public) certain payments and other transfers of value made to physicians and teaching hospitals and, beginning with disclosures in 2022, to certain non-physician practitioners. State laws may also require disclosure of pharmaceutical pricing information and marketing expenditures. Many of these laws and regulations contain requirements that are subject to interpretation. Outside the U.S., other countries have implemented requirements for disclosure of financial interactions with healthcare providers and additional countries may consider or implement such laws.

We are subject to various federal and foreign laws that govern our international business practices with respect to payments to government officials. Those laws include the U.S. Foreign Corrupt Practices Act, or FCPA, which prohibits U.S. companies and their representatives from paying, offering to pay, promising, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. In many countries, the health care professionals we regularly interact with may meet the FCPA's definition of a foreign government official. We are also subject to U.K. Bribery Act 2010, or the Bribery Act, which proscribes giving and receiving bribes in the public and private sectors, bribing a foreign public official, and failing to have adequate procedures to prevent employees and other agents from giving bribes. U.S. companies that conduct business in the United Kingdom, or U.K., generally will be subject to the Bribery Act.

We are subject to federal laws, including the Medicaid Drug Rebate Program, that require pharmaceutical manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement under government healthcare programs.

Our collection and use of personal data as part of our business activities is subject to various privacy and data security laws and regulations, including oversight by various regulatory or other governmental bodies, in the U.S., E.U., U.K., Canada, Australia and other jurisdictions. Such laws and regulations have the potential to affect our business materially, continue to evolve and increasingly are being enforced.

Our present and future business has been and will continue to be subject to various other laws and regulations. Various laws, regulations and recommendations relating to safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import, export and use and disposal of hazardous or potentially hazardous substances are or may be applicable to our activities. In addition, as we expand our pipeline and contemplate different approaches that may incorporate the use of medical devices, such approaches may necessitate compliance with regulatory laws applicable to medical devices, including those governing the testing, manufacture, approval, distribution, and marketing of medical devices. Furthermore, the extent of government regulation, which might result from future legislation or administrative action, cannot accurately be predicted.

We have a corporate compliance program designed to actively identify, prevent and mitigate risk through the implementation of compliance policies and systems and through the promotion of a culture of compliance. We expect to continue to devote substantial resources to maintain, administer and expand the compliance program globally. We cannot be certain, however, that our compliance program will ensure compliance with the various complex laws and regulations to which we are subject now or in the future.



## EMPLOYEES AND HUMAN CAPITAL MANAGEMENT

As of December 31, 2020, we had approximately 3,400 employees. Of these employees, approximately 2,800 were based in the U.S. and approximately 600 were based outside the U.S. Our employees are not covered by a collective bargaining agreement, except for a small number of employees outside the U.S. We consider our relations with our employees to be good. We continue to face intense competition for our personnel from our competitors and other companies throughout our industry and from universities and research institutions.

We rely on skilled, experienced, and innovative employees to conduct the operations of our company. The biotechnology industry is very competitive and recruiting and retaining such employees is important to the continued success of our business. We are committed to building an outstanding, committed and passionate team at Vertex, and we focus on a culture that values inclusion, diversity and equity. We believe that each employee brings unique perspectives and strengths, and by embracing these strengths, we can do our best work for patients. We focus on recruiting, retaining, and developing employees from a diverse range of backgrounds to conduct our research, development, and commercial activities.

Our commitment to diversity, inclusion and equity begins with our executive management team: four of our ten members are women and/or from diverse racial and ethnic groups. On our Board of Directors, six of our ten members are women and/or from a diverse racial and ethnic group. As of December 31, 2020, women represented 53% of our global workforce and 38% of our leadership (VP and above). As of December 31, 2020, 34% of our U.S. workforce, and 18% of our U.S. leadership (VP and above), were from diverse racial and ethnic groups.

The leader of our diversity, inclusion, and equity strategy and efforts is a Vice President in our human resources group. Additionally, our employee resource networks promote connectivity and collaboration across levels and functions, and engage colleagues in personal and professional development opportunities, including mentoring, community outreach, and cultural awareness activities.

To promote our employees’ continued well-being and development, we offer a variety of inclusive benefits and opportunities. We offer comprehensive work-life benefits, including health, dental, and income protection, such as life insurance and retirement savings programs. In 2020, we enhanced and expanded our employee benefits in response to the COVID-19 pandemic. For example, we increased company-wide personal time off, provided resources to enable employees to work from home, and introduced and expanded mental wellness tools for all employees. Our management has continued to assess and respond to the evolving needs of our workforce throughout the pandemic.

In addition, we provide our employees with career development and advancement opportunities, including job rotations, mentoring and managerial training. We also are committed to identifying and developing our next generation leaders and have developed programs focused on talent and succession for critical roles in our organization.

## Succession Planning

In 2020, we successfully executed a leadership succession plan with the transition of Dr. Kewalramani to the role of Chief Executive Officer and our former Chief Executive Officer, Dr. Leiden, to the role of Executive Chairman. This transition was the culmination of a multi-year planning process led by our independent directors.

## ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk, and you should carefully consider the risks and uncertainties described below in addition to the other information included or incorporated by reference in this Annual Report on Form 10-K. If any of the following risks or uncertainties actually occurs, our business, financial condition or results of operations would likely suffer, possibly materially. In that case, the trading price of our common stock could decline.

## SUMMARY OF RISK FACTORS

Our business is subject to numerous risks and uncertainties, discussed in more detail in the following section. These risks include, among others, the following key risks:

## Risks Related to Our Business

- All of our product revenues and the vast majority of our total revenues are derived from sales of medicines for the treatment of CF. If we are unable to continue to increase revenues from sales of our CF medicines, our business would be materially harmed and the market price of our common stock would likely decline.

• We are investing significant resources in the research and development of therapies for serious diseases other than CF, and if we are unable to successfully commercialize one or more of these therapies, our business could be materially harmed.

• If our competitors bring drugs with superior product profiles to market, our drugs may not be competitive and our revenues could decline.

- If we discover safety issues with any of our products or if we fail to comply with continuing U.S. and applicable foreign regulations, commercialization efforts for the product could be negatively affected, the approved product could lose its approval or sales could be suspended, and our business could be materially harmed.

- If physicians and patients do not accept our medicines, or if patients do not remain on treatment or comply with their prescribed dosing regimen, our product revenues would be materially harmed in future periods.

• Government and other third-party payors seek to contain costs of health care through legislative and other means. If they fail to provide coverage and adequate reimbursement rates for our products, our revenues will be harmed.

• We have experienced challenges commercializing products outside of the U.S, and our future revenues will be dependent on our ability to obtain adequate reimbursement for our products.

• We have limited experience developing cell and genetic therapies and could experience challenges with these programs, which could result in delays or prevent the development, manufacturing and commercialization of our cell and genetic therapies.

## Risks Related to Development and Clinical Testing of Our Products and Drug Candidates

• Our drug candidates remain subject to clinical testing and regulatory approval. Our future success is dependent on our ability to successfully develop additional drug candidates for both CF and non-CF indications.

• If we are unable to obtain regulatory approval, we will be unable to commercialize our drug candidates.

- If clinical trials are prolonged or delayed, our development timelines for the affected development program could be extended, our costs to develop the drug candidate could increase and the competitive position of the drug candidate could be adversely affected.

## Risks Related to Government Regulation

- If regulatory authorities interpret any of our conduct, including our marketing practices, as being in violation of applicable health care laws, including fraud and abuse laws, laws prohibiting off-label promotion, disclosure laws or other similar laws, we may be subject to civil or criminal penalties.



- If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other governmental pricing programs in the U.S., we could be subject to additional reimbursement requirements, penalties, sanctions and fines which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

- If our processes and systems are not compliant with regulatory requirements, we could be subject to restrictions on marketing our products or could be delayed in submitting regulatory filings seeking approvals for our drug candidates.

- We are subject to various and evolving laws and regulations governing the privacy and security of personal data, and our failure to comply could adversely affect our business, result in fines and/or criminal penalties, and damage our reputation.

## Risks Related to Business Development Activities

- Our ability to execute on our long-term strategy depends in part on our ability to engage in transactions and collaborations with other entities that add to our pipeline or provide us with new commercial opportunities.

- We may not realize the anticipated benefits of acquisitions of businesses or technologies, and the integration following any such acquisition may disrupt our business and management.

- We face risks in connection with existing and future collaborations with respect to the development, manufacture and commercialization of our products and drug candidates.

• We may not be able to attract collaborators or external funding for the development and commercialization of certain of our drug candidates.

## Risks Related to Third-Party Manufacturing and Reliance on Third Parties

- We depend on third-party manufacturers to manufacture our products and the materials we require for our clinical trials. We may not be able to maintain these relationships and could experience supply disruptions outside of our control.

- We rely on third parties to conduct pre-clinical work, clinical trials and other activities, and those third parties may not perform satisfactorily, including failing to meet established deadlines for the completion of such studies and/or trials or failing to satisfy regulatory requirements.

## Risks Related to Intellectual Property

- If our patents do not protect our drugs or our drugs infringe third-party patents, we could be subject to litigation which could result in injunctions preventing us from selling our products or substantial liabilities.

- Uncertainty over intellectual property in the pharmaceutical and biotechnology industry has been the source of litigation and other disputes, which is inherently costly and unpredictable.

- We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

## Risks Related to Our Operations

• Risks associated with operating in foreign countries could materially adversely affect our business.

• We are subject to risks associated with the global COVID-19 pandemic.

• If we fail to attract and retain skilled employees, our business could be materially harmed.

• Our business faces potential risks relating to the United Kingdom’s withdrawal from the European Union.

## Risks Related to Financial Results and Holding Our Common Stock

• Our stock price may fluctuate.

• Changes in tax laws, regulations and treaties could affect our future taxable income.



## Risks Related to Our Business

All of our product revenues and the vast majority of our total revenues are derived from sales of medicines for the treatment of CF. If we are unable to continue to increase revenues from sales of our CF medicines, our business would be materially harmed and the market price of our common stock would likely decline.

Our net product revenues and the vast majority of our total revenues are derived from the sale of our CF medicines. As a result, our future success is dependent upon our ability to increase revenues from sales of our CF medicines. This will require us to continue to gain approval and reimbursement for our triple combination therapy in ex-U.S. markets and successfully develop and commercialize our triple combination therapy for younger children with CF.

Our concentrated source of revenues presents a number of risks to our business, including:

• that one or more competing therapies may successfully be developed as a treatment for people with CF;

- that reimbursement policies of payors and other third parties may make it difficult to obtain reimbursement or reduce the net price we receive for our products;

• that we may experience manufacturing or supply disruptions for our CF medicines; and

• that we may experience adverse developments with respect to development or commercialization of our CF medicines and/or CF drug candidates.

If any of the above risks were to materialize, if we are otherwise unable to increase revenues from sales of our CF medicines, or if we do not meet the expectations of investors or public equity market analysts, our business would be materially harmed and our ability to fund our operations could be adversely affected. For example, if we are unable to increase revenues from sales of our CF medicines, our ability to fund our research and development programs for the discovery and development or acquisition of new products would be harmed, which would limit our ability to diversify our revenue base and our stock price would likely be adversely affected.

We are investing significant resources in the research and development of therapies for serious diseases other than CF, and if we are unable to successfully commercialize one or more of these therapies, our business could be materially harmed.

We are investing significant resources in the research and development of medicines for serious diseases including AAT deficiency, APOL1-mediated kidney diseases, pain, beta thalassemia, SCD, T1D, DMD and DM1. Some of these programs have progressed into clinical trials, while others are still in pre-clinical development. Product development is highly uncertain and expensive, and product candidates that may appear promising in the early phases of research and development may fail to reach commercial success for many reasons, including the failure to demonstrate acceptable clinical trial results or obtain marketing approval, the inability to manufacture or commercialize the product candidate on economically feasible terms, or the appearance of safety issues. For example, in October 2020, we discontinued development of VX-814, a drug candidate for the treatment of AAT, based on the safety and pharmacokinetic profile observed in a Phase 2 clinical trial.

Even if we gain marketing approval for one or more pipeline products, we cannot be sure that we will obtain market acceptance or adequate reimbursement levels from third-party payors or foreign governments for such products. Additionally, many of the therapies that we are developing in our pipeline target rare diseases that affect a limited number of patients. There can be no guarantee that we will effectively identify patients that are eligible for enrollment in our clinical trials or treatment with our drug candidates. Even if we do successfully identify eligible patients, the number of patients that our drug candidates are able to treat may turn out to be lower than we expect or new patients may become increasingly difficult to identify, each of which may adversely affect our revenues and materially harm our business. For these and other reasons, we may never be successful in expanding our pipeline and future revenue may continue to depend on sales of our CF medicines.



## If our competitors bring drugs with superior product profiles to market, our drugs may not be competitive and our revenues could decline.

A number of companies are seeking to identify and develop drug candidates for the treatment of CF and other therapeutic areas we are targeting with our research and development activities. Our success in rapidly developing and commercializing our CF medicines may increase the resources that our competitors allocate to the development of potential competitive treatments. If one or more competing therapies are successfully developed as a treatment for people with CF or any of the other diseases we are currently targeting in our pipeline, our products and our net product revenues could face competitive pressures. If one or more competing therapies prove to be superior to our then existing products and/or drug candidates, our business could be materially adversely affected.

In addition, our business faces competition from major pharmaceutical companies possessing substantially greater financial resources than we possess. We also face competition from numerous smaller public and private companies, academic institutions, government agencies, public and private research organizations and charitable venture philanthropy organizations that conduct research, seek patent protection and/or establish collaborative arrangements for research, development, manufacturing and commercialization.

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and other early-stage companies also may prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our products and any drugs that we develop in the future may not be able to compete effectively with marketed drugs or new drugs that may be developed by competitors. The risk of competition is particularly important to our company because substantially all of our revenues as well as our most advanced drug candidates are related to the treatment of people with CF. There are many other companies developing drugs for the same patient populations that we are pursuing. In order to compete successfully in these areas, we must demonstrate improved safety, efficacy and/or tolerability, ease of manufacturing, and gain and maintain market acceptance over competing drugs.

If we discover safety issues with any of our products or if we fail to comply with continuing U.S. and applicable foreign regulations, commercialization efforts for the product could be negatively affected, the approved product could lose its approval or sales could be suspended, and our business could be materially harmed.

Our products are subject to continuing regulatory oversight, including the review of additional safety information. Drugs are more widely used by patients once approval has been obtained and therefore side effects and other problems may be observed after approval that were not seen or anticipated, or were not as prevalent or severe, during pre-approval clinical trials or nonclinical studies. The subsequent discovery of previously unknown or underestimated problems with a product could negatively affect commercial sales of the product, result in restrictions on the product or lead to the withdrawal of the product from the market. Three of our commercial products are combination products, and each of our products shares at least one active pharmaceutical ingredient with another of our products. As a result, if any of our CF products were to experience safety issues, our other CF products may be adversely affected. The reporting of adverse safety events involving our products or public speculation about such events could cause our stock price to decline or experience periods of volatility. Our business also may be materially harmed by impaired sales of our products, denial or withdrawal of regulatory approvals, required label changes or additional clinical trials, reputational harm, or government investigations or lawsuits brought against us.

In addition, our products are subject to ongoing regulatory requirements governing the testing, manufacturing, labeling, packaging, storage, advertising, promotion, sale, distribution, import, export, recordkeeping and submission of safety and other post-market information. We and our third-party manufacturers must comply with cGMP and other applicable regulations governing the manufacturing and distribution of our products. Regulatory authorities periodically inspect our drug manufacturing facilities, and those of our third-party manufacturers, to evaluate compliance with cGMP and other regulatory requirements.

If we or our collaborators, or third-parties acting on our behalf, fail to comply with applicable continuing regulatory requirements, we or our collaborators may be subject to fines, suspension or withdrawal of regulatory approvals for specific



products, product recalls and seizures, operating restrictions and/or criminal prosecutions, any of which could have a material adverse effect on our business, reputation, financial condition and results of operations.

If physicians and patients do not accept our medicines, or if patients do not remain on treatment or comply with their prescribed dosing regimen, our product revenues would be materially harmed in future periods.

Our medicines may not gain or maintain market acceptance among physicians and patients. Effectively marketing our drugs and any of our drug candidates or investigational therapies, if approved, requires substantial efforts, both prior to launch and after approval. Physicians may elect not to prescribe our drugs or recommend our cell or genetic therapies, and patients may elect not to take them or receive them or they may discontinue use of our drugs after initiation of treatment, for a variety of reasons including:

• prevalence and severity of adverse side effects;

• lack of reimbursement availability from third-party payors, including governmental entities;

• lower demonstrated efficacy, safety and/or tolerability compared to alternative treatment methods;

• lack of cost-effectiveness;

• a decision to wait for the approval of other therapies in development that have significant perceived advantages over our drug;

• convenience and ease of administration;

• other potential advantages of alternative treatment methods; and

• inadequate sales, marketing and/or distribution support, including as a result of limitations or restrictions resulting from COVID-19.

If our medicines fail to achieve or maintain market acceptance, we may not be able to generate significant revenues in future periods.

Government and other third-party payors seek to contain costs of health care through legislative and other means. If they fail to provide coverage and adequate reimbursement rates for our products, our revenues will be harmed.

Sales of our products depend in part upon the availability of reimbursement from third-party payors. Third-party payors include government health programs such as Medicare and Medicaid in the U.S. and the national health care systems in ex-U.S. markets, managed care providers, private health insurers and other organizations. The trend in the health care industry is cost containment, and efforts of third-party payors to contain or reduce health care costs may adversely affect our ability to establish or maintain appropriate prices for our products or any drugs that we may develop and commercialize.

In most ex-U.S. markets, the pricing and reimbursement of therapeutic and other pharmaceutical products is subject to governmental control, and government authorities are making greater efforts to limit or regulate the price of drug products. In the U.S., there have been, and we expect that there will continue to be, a number of federal and state proposals to implement governmental controls that are similar to those that currently exist in Europe. For example, the ACA required manufacturers of Medicare Part D brand name drugs to provide discounts on those drugs to Medicare Part D beneficiaries during the coverage gap; increased the rebates paid by pharmaceutical companies to state Medicaid programs on drugs covered by Medicaid; and imposed an annual fee, which increases annually, on sales by branded pharmaceutical manufacturers.

There also has been an increase in legislation and regulations related to drug pricing and drug pricing transparency. In the U.S., various states, including Nevada, Maryland, Louisiana, New York, California, Washington, Massachusetts, Connecticut, Utah, Minnesota and Oregon, have passed legislation requiring companies to disclose extensive information relating to drug prices, drug price increases, and spending on research, development, and marketing. Although it is not clear what states will do with the collected information, some laws were designed to obtain additional product discounts. We may continue to see more state action requiring additional disclosures or other actions. In addition, we could see increased federal activity related to drug pricing and transparency requiring disclosures or other actions instead of, or in addition to, state requirements. Similar initiatives are also occurring in, or being considered by, some of the ex-U.S. markets, including Italy and Brazil.



Complying with these laws is expensive and requires significant personnel and operational resources and deters focus on our business. Additionally, any additional required discounts would adversely affect the pricing of, and revenues from, our products. Finally, while we seek to comply with all statutory and regulatory requirements, we face increased enforcement activity by the U.S. federal government, state governments, and private payors against pharmaceutical and biotechnology companies for pricing and reimbursement-related issues.

Recently, there also has been rulemaking related to importation of prescription drugs from Canada as well as guidance related to importation of prescription drugs from other foreign countries. HHS also has issued a regulation seeking to establish a model for reference pricing of certain physician-administered drugs. While the recent regulation does not apply to our current medicines, it could affect future medicines. Additionally, in 2020, the Trump Administration issued several executive orders relating to drug pricing which were intended to broadly impact the pharmaceutical industry. Likewise, HHS recently issued a final regulation adopting changes to anti-kickback laws for rebates offered to pharmacy benefit managers. We expect such government scrutiny over drug pricing, reimbursement, and distribution to increase. Potential future government regulation of drug prices or reimbursement creates uncertainties about our portfolio and could have a material adverse effect on our operations.

Third-party payors throughout the world also have been attempting to control drug spending through various other actions, and this is expected to be an area of intensified focus for all payors in light of the global economic pressures, including due to the COVID-19 pandemic. In reimbursement negotiations, many payors are demanding price discounts and caps on total expenditures and limiting both the types and variety of drugs that they will cover if they are not able to secure them. As part of these negotiations, many ex-U.S. government payors also are requiring companies to establish product cost-effectiveness as a condition of reimbursement and companies' data-backed explanations are assessed by government agencies set up for this purpose. These cost-effectiveness reviews may not account for many of the benefits provided by innovative medicines, and for the most part, have not taken into account the specific circumstances of products that treat rare diseases. This has led to conclusions that certain medicines, including our products in certain jurisdictions, are not cost-effective. As a result, certain countries have declined to reimburse, or delayed their reimbursement, of some of our products. Although not mandated in the U.S., various organizations have started advocating for cost-effectiveness analyses in the U.S. If U.S. payors were to adopt such assessments and make negative coverage determinations, it could adversely affect our product revenues. Our business would be materially adversely affected if we are not able to obtain or maintain coverage and reimbursement of our products from third-party payors on a broad, timely or satisfactory basis or if such coverage is subject to overly broad or restrictive utilization management controls.

The U.S. government, individual states and some foreign jurisdictions also have been aggressively pursuing legislative and regulatory reforms that could affect our ability to sell products. For example, in the U.S., there have been ongoing federal legislative and administrative efforts to repeal, substantially modify or invalidate some or all of the provisions of the ACA. Various portions of the ACA are subject to legal challenges in various jurisdictions, including the U.S. Supreme Court, which could affect coverage and payment for medicines. Other reforms include the Bipartisan Budget Act of 2018, which contained various provisions that affect coverage and reimbursement of drugs, including an increase in the discount that manufacturers of Medicare Part D brand name drugs must provide to Medicare Part D beneficiaries during the coverage gap from 50% to 70%. There are a number of additional bills pending in Congress that would affect drug pricing in the Medicare and Medicaid programs. Additional healthcare reform efforts have sought to address issues related to the COVID-19 pandemic, including an expansion of telehealth coverage under Medicare and accelerated or advanced Medicare payments to healthcare providers. Adoption of new healthcare reform legislation at the federal or state level could affect demand for, or pricing of, our products or product candidates if approved for sale. We cannot, however, predict the ultimate content, timing or effect of any healthcare reform legislation or action, or its impact on us, including increased compliance requirements and costs, all of which may adversely affect our future business, operations and financial results.

The increasing availability and use of innovative specialty pharmaceuticals for rare diseases, combined with their relative higher cost as compared to other types of pharmaceutical products, is generating significant third-party payor interest in developing cost-containment strategies targeted to this sector. Government regulations in both U.S. and ex-U.S. markets could further limit the prices that can be charged for our products and may limit our commercial opportunity. The increasing use of cost-effectiveness assessments in markets around the world and the financial challenges faced by many governments may lead to significant adverse effects on our business. Additionally, any legislation or regulatory changes or relaxation of laws that restrict imports of drugs from other countries, revisions to reimbursement or pharmaceuticals under government programs or general budget control actions also could reduce the net price we receive for our products.



We have experienced challenges commercializing products outside of the U.S., and our future revenues will be dependent on our ability to obtain adequate reimbursement for our products.

In most ex-U.S. markets, the pricing and reimbursement of therapeutic and other pharmaceutical products is subject to governmental control. Given recent global economic pressures, including due to the COVID-19 pandemic, and geopolitical uncertainty, government authorities throughout the world are increasingly attempting to limit or regulate the price of drug products. The reimbursement process in ex-U.S. markets can take a significant time to conclude and reimbursement decisions are made on a country-by-country basis.

Our medicines treat life-threatening conditions and address relatively small patient populations, and our research and development programs are primarily focused on developing medicines to treat similar diseases. Particular attention is being paid by payors, including government and private payors, to these types of high-cost medicines, and countries are increasingly refusing to reimburse costly medicines. We have experienced challenges in obtaining timely reimbursement for our products in various countries outside the U.S. We continue to experience such challenges in some countries. For example, we obtained reimbursement for ORKAMBI and SYMKEVI in England in the fourth quarter of 2019, four years after ORKAMBI's initial approval in 2015. Our future product revenues, including from TRIKAFTA/KAFTRIO, depend on, among other things, our ability to complete reimbursement discussions in ex-U.S. markets for our products. There is no assurance that coverage and reimbursement will be available outside of the U.S. for our four approved medicines or any future medicine, and, even if it is available, whether the timing or the level of reimbursement will be sufficient to allow us to market our medicines. Adverse pricing limitations or a delay in obtaining coverage and reimbursement would decrease our future net product revenues and harm our business.

We have limited experience developing cell and genetic therapies and could experience challenges with these programs, which could result in delays or prevent the development, manufacturing and commercialization of our cell and genetic therapies.

We are investing significant resources in the research, development and manufacturing of cell and genetic therapies. While we have previously successfully developed, manufactured and commercialized several small molecule drugs, we have limited experience with the development, manufacture and commercialization of cell and genetic therapies. Development, manufacturing and commercialization of cell and genetic therapies are subject to the same risks and uncertainties as development, manufacturing and commercializing small molecules. In addition:

- the manufacturing processes for cell and genetic therapies are different and more complex than the manufacturing processes required for small molecule drugs, and require different systems, equipment, facilities and expertise to develop and maintain;

• we may encounter difficulties in the production of our cell and genetic therapies and ensuring that the product meets required specifications;

- there have been a limited number of regulatory approvals for genetic therapies to date, the regulatory requirements governing genetic therapies continue to evolve, and regulatory positions and interpretations can change or lead to delays or significant unexpected costs with respect to our genetic therapy programs;

- the commercial success of cell or genetic therapies, including CTX001, if approved, will depend in part on the medical community, patients, and third-party or governmental payers accepting cell or genetic therapy products in general, and the applicable medicine as medically useful, cost-effective, and safe; and

- market acceptance will be dependent in part on the prevalence and severity of side effects associated with the procedure by which the cell or genetic therapy is administered, including, with respect to CTX001, if approved, the prevalence and severity of any side effects resulting from the myeloablative preconditioning regimen.

For programs addressing rare genetic diseases with small patient populations, we may not be able to identify, recruit and enroll a sufficient number of patients, or those with required or desired characteristics, to complete our clinical studies in an adequate and timely manner. Additionally, patients may be unwilling to participate in our clinical trials because of concerns that cell and genetic therapies are unsafe or unethical, negative publicity from adverse events in the biotechnology or gene therapy industries or for other reasons, including competitive clinical studies for similar patient populations.



In order to develop and commercialize any future cell or genetic therapies, we will need to incur substantial expenditures to develop, contract for, or otherwise arrange for the necessary manufacturing capabilities. Additionally, the manufacture of cell and genetic therapies requires significant expertise. Even with the relevant experience and expertise, manufacturers of cell and genetic therapy products often encounter difficulties in production, including difficulties with production costs and yields, quality control, and compliance with federal, state and foreign regulations. We cannot make any assurances that these problems will not occur, or that we will be able to resolve or address problems that occur in a timely manner, or at all.

To the extent we develop capabilities internally, there are many risks that could result in delays and additional costs, including the need to hire and train qualified employees and obtain access to necessary equipment and third-party technology. To the extent we partner with third parties to manufacture our cell or genetic therapies, any complexity in the manufacture of our products and product candidates may require lengthy technology transfers.

There also is significant uncertainty related to the insurance coverage and reimbursement of cell or genetic therapy products, including gene therapies that are potential one-time treatments. It is difficult to predict what third party payors, including U.S. or ex-U.S. governments or private insurance companies, will decide with respect to reimbursement for novel cell and genetic therapies like the ones in our pipeline. Additionally, reimbursement rates for cell and genetic therapies approved before ours could create an adverse environment for reimbursement of any therapies we ultimately commercialize. The administration of our products may require procedures for the collection of cells from patients, followed by other procedures either before or after delivery of the cell or genetic therapy. The manner and level at which reimbursement is provided for these services also is important. An inadequate reimbursement for such services may adversely affect physician decision to recommend any product for which we obtain approval in the future and our ability to market or sell them.

Given there are only a few approved cell and genetic therapy products, it also is difficult to determine how long it will take or reasonably estimate the costs to develop, manufacture and commercialize cell or genetic therapies. In addition, our cell-based therapies include approaches involving devices, which are subject to additional regulatory requirements. If we are unable to successfully develop, manufacture or commercialize such therapies on a timely or profitable basis, or at all, we may not realize benefits or generate cash flows based on our investments in these programs and our business, financial condition, results of operations and our stock price would likely be adversely affected.

We are dependent upon a small number of customers for a significant portion of our revenue, and the loss of, or significant reduction in sales to, these customers would adversely affect our results of operations.

In the U.S., we sell our products principally to a limited number of specialty pharmacy and specialty distributors, which subsequently resell our products to patients and health care providers. Internationally, we sell our products primarily to a limited number of specialty distributors and retail chains, as well as hospitals and clinics. We expect this significant customer concentration to continue for the foreseeable future. Our ability to generate and grow sales of our CF medicines will depend significantly on the extent to which these specialty distributors and specialty pharmacies are able to provide adequate distribution of our products to patients and healthcare providers. The loss of any large customer, a significant reduction in sales we make to them, any cancellation of orders they have made with us, or any failure to pay for the products we have shipped to them could adversely affect our business, financial condition and results of operations.

## Risks Related to Development and Clinical Testing of Our Products and Drug Candidates

Our drug candidates remain subject to clinical testing and regulatory approval. Our future success is dependent on our ability to successfully develop additional drug candidates for both CF and non-CF indications.

Our business depends upon the successful development and commercialization of drug candidates. These drug candidates are in various stages of development and must satisfy rigorous standards of safety and efficacy before they can be approved for sale by the FDA or comparable foreign regulatory authorities. To satisfy these standards, we must allocate resources among our various development programs and must engage in expensive and lengthy testing of our drug candidates. Discovery and development efforts for new pharmaceutical products, including new combination therapies, are resource-intensive and may take 10 to 15 years or longer for each drug candidate. Despite our efforts, our drug candidates may not:

• offer therapeutic or other improvement over existing competitive therapies;

- show the level of safety and efficacy, including the level of statistical significance, required by the FDA or other regulatory authorities for approval of a drug candidate;



• meet applicable regulatory standards;

• be capable of being produced in commercial quantities at acceptable costs; or

• if approved for commercial sale, be successfully marketed as pharmaceutical products.

We have recently completed and/or have ongoing or planned clinical trials for several of our drug candidates. The strength of our product portfolio and pipeline will depend in large part upon the outcomes of these clinical trials, including clinical trials evaluating our triple combination therapy in younger children with CF and our clinical trials of potential medicines to treat other diseases. Results of our clinical trials and findings from our nonclinical studies, including toxicology findings in nonclinical studies conducted concurrently with clinical trials, could lead to abrupt changes in our development activities, including the possible cessation of development activities associated with a particular drug candidate or program. For example, in October 2020, we discontinued development of VX-814, a drug candidate for the treatment of AAT, based on the safety and pharmacokinetic profile observed in the clinical trial.

Moreover, clinical data are often susceptible to varying interpretations, and many companies that have believed their drug candidates performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of their drug candidate. Furthermore, results from our clinical trials may not meet the level of statistical significance or otherwise provide the level of evidence or safety and efficacy required by the FDA or other regulatory authorities for approval of a drug candidate. Finally, clinical trials are expensive and require significant operational resources to implement and maintain.

Many companies in the pharmaceutical and biotechnology industries, including our company, have suffered significant setbacks in later-stage clinical trials even after achieving promising results in earlier-stage clinical trials. For example, the results from completed preclinical studies and clinical trials may not be replicated in later clinical trials, and ongoing clinical trials for our drug candidates may not be predictive of the results we may obtain in later-stage clinical trials or of the likelihood of approval of a drug candidate for commercial sale. In addition, from time to time, we report interim data from our clinical trials. Interim data from a clinical trial may not be predictive of final results from the clinical trial. Failure to advance drug candidates through clinical development could impair our ability to ultimately commercialize products, which could materially harm our business and long-term prospects.

If we are unable to obtain regulatory approval, we will be unable to commercialize our drug candidates.

The time required to complete clinical trials and to satisfy the FDA and other countries' regulatory review processes is uncertain and typically takes many years. Our analysis of data obtained from nonclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We also may encounter unanticipated delays or increased costs due to government regulation from future legislation or administrative action or changes in governmental policy during the period of drug development, clinical trials and governmental regulatory review.

We may seek a Fast Track, Priority Review, Breakthrough Therapy, and/or RMAT designation for some of our drug candidates. Drug candidates that receive one or more of these designations may be eligible for, among other things, a priority regulatory review. Each of these designations is within the discretion of the FDA. Accordingly, even if we believe one of our drug candidates meets the criteria for Fast Track, Priority Review, Breakthrough Therapy and/or RMAT designation, the FDA may disagree and instead determine not to make such designation. The receipt of one or more of these designations for a drug candidate does not guarantee a faster development process, review or approval compared to drugs developed or considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of our drugs or drug candidates qualifies for Fast Track, Priority Review, Breakthrough Therapy and/or RMAT designation, the FDA may later decide to withdraw such designation if it determines that the drug or drug candidate no longer meets the conditions for qualification.

Any failure to obtain regulatory approvals for a drug candidate would prevent us from commercializing that drug candidate. Any delay in obtaining required regulatory approvals could materially adversely affect our ability to successfully commercialize a drug candidate. Furthermore, any regulatory approval to market a drug may be subject to limitations that we do not expect on the indicated uses for which we may market the drug. Any such limitations could reduce the size or demand of the market for the drug.

We also are subject to numerous foreign regulatory requirements governing the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. Non-U.S. jurisdictions have different approval



procedures than those required by the FDA, and these jurisdictions may impose additional testing requirements for our drug candidates. The foreign regulatory approval process includes all of the risks associated with the FDA approval process described above, as well as risks attributable to the satisfaction of foreign requirements. Approval by the FDA does not ensure approval by regulatory authorities outside the U.S. and approval by a foreign regulatory authority does not ensure approval by the FDA. In addition, although the FDA may accept data from clinical trials conducted outside the U.S., acceptance of this data is subject to conditions imposed by the FDA. For example, the clinical trial must be well designed and conducted and performed by qualified investigators in accordance with ethical principles. The trial population also must adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. In addition, while these clinical trials are subject to applicable local laws, FDA acceptance of the data will depend on its determination that the trials also complied with all applicable U.S. laws and regulations. If the FDA does not accept the data from any trial that we conduct outside the U.S., it would likely result in the need for additional trials, which would be costly and time-consuming and delay or permanently halt our development of the applicable drug candidate.

If clinical trials are prolonged or delayed, our development timelines for the affected development program could be extended, our costs to develop the drug candidate could increase and the competitive position of the drug candidate could be adversely affected.

We cannot predict whether or not we will encounter problems with any of our completed, ongoing or planned clinical trials that will cause us or regulatory authorities to delay or suspend clinical trials, or delay the analysis of data from our completed or ongoing clinical trials. Among the factors that could delay our development programs are:

- ongoing discussions with the FDA or comparable foreign authorities regarding the scope or design of our clinical trials and the number of clinical trials we must conduct;

- delays in enrolling volunteers or patients into clinical trials, including as a result of low numbers of patients that meet the eligibility criteria for the trial;

• a lower than anticipated retention rate of volunteers or patients in clinical trials;

• the need to repeat clinical trials as a result of inconclusive results, unforeseen complications in testing or clinical investigator error;

• inadequate supply or deficient quality of drug candidate materials or other materials necessary for the conduct of our clinical trials;

- unfavorable FDA or foreign regulatory authority inspection and review of a manufacturing facility that supplied clinical trial materials or its relevant manufacturing records or a clinical trial site or records of any clinical or preclinical investigation;

• unfavorable scientific results from clinical trials;

- serious and unexpected drug-related side-effects experienced by participants in our clinical trials or by participants in clinical trials being conducted by our competitors to evaluate drug candidates with similar mechanisms of action or structures to therapies that we are developing;

- favorable results in testing of our competitors’ drug candidates, or FDA or foreign regulatory authority approval of our competitors’ drug candidates; or

- action by the FDA or a foreign regulatory authority to place a clinical hold or partial clinical hold on a trial or compound or deeming the clinical trial conduct as problematic.

Our ability to enroll patients in our clinical trials in sufficient numbers and on a timely basis is subject to a number of factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease, the number of other clinical trials ongoing and competing for patients in the same indication, the eligibility criteria for the clinical trial, and the ongoing COVID-19 pandemic. In addition, patients may drop out of our clinical trials or may be lost to follow-up medical evaluation after treatment ends, and this could impair the validity or statistical significance of the trials. Clinical trials are expensive and require significant operational



resources. Delays in patient enrollment or unforeseen drop-out rates may result in increased costs and longer development times.

We, our collaborators, the FDA or other applicable regulatory authorities may suspend clinical trials of a drug candidate at any time if we or they believe the healthy volunteers or patients participating in such clinical trials are being exposed to unacceptable health risks or for other reasons. Any such suspension could materially adversely affect the development of a particular drug candidate and our business.

## Risks Related to Government Regulation

If regulatory authorities interpret any of our conduct, including our marketing practices, as being in violation of applicable health care laws, including fraud and abuse laws, laws prohibiting off-label promotion, disclosure laws or other similar laws, we may be subject to civil or criminal penalties.

We are subject to health care fraud and abuse laws, such as the federal False Claims Act and anti-kickback laws, which prohibit off-label product promotion and other similar laws and regulations both in the U.S. and in non-U.S. markets.

The federal anti-kickback law prohibits knowingly and willfully offering, paying, soliciting, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the ordering, furnishing, arranging for or recommending of an item or service that is reimbursable, in whole or in part, by a federal health care program, such as Medicare or Medicaid. Because of the broad scope of the prohibition, most financial interactions between pharmaceutical manufacturers and prescribers, purchasers, third party payors and patients would be subject to the statute. Although there are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution, the exceptions and safe harbors are narrow. Financial interactions must therefore be structured carefully to qualify for protection or otherwise withstand scrutiny.

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to get a false claim paid. Pharmaceutical companies have been prosecuted under these laws for a variety of alleged promotional and marketing activities, such as providing free product to customers with the expectation that the customers would bill federal programs for the product; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in promotion for uses that the FDA has not approved, known as “off-label” uses, that caused claims to be submitted to Medicaid for those off-label uses; submitting inflated “best price” information to the Medicaid Rebate Program; and certain manufacturing-related violations. The scope of this and other laws may expand in ways that make compliance more difficult and expensive.

Although physicians are permitted, based on their medical judgment, to prescribe products for indications other than those approved by the FDA, manufacturers are prohibited from promoting their products for such off-label uses. We market our products to eligible people with CF for whom the applicable product has been approved and provide promotional materials and training programs to physicians regarding the use of each product in these patient populations. These eligible people do not represent all people with CF. If the FDA determines that our promotional materials, training or other activities constitute off-label promotion, it could request that we modify our training or promotional materials or other activities, conduct corrective advertising or subject us to regulatory enforcement actions, including the issuance of a warning letter, injunction, seizure, civil fine and criminal penalties. It also is possible that other federal, state or foreign enforcement authorities might take action if they believe that the alleged improper promotion led to the submission and payment of claims for an off-label use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. Even if it is later determined we were not in violation of these laws, we may be faced with negative publicity, incur significant expenses defending our actions and have to divert significant management resources from other matters.

In the U.S., federal and state laws regulate financial interactions between pharmaceutical manufacturers and healthcare providers, require disclosure to government authorities and the public of such interactions, and mandate the adoption of compliance standards or programs. For example, the so-called federal “sunshine law” requires pharmaceutical manufacturers to report annually to the Centers for Medicare & Medicaid Services, or CMS, payments or other transfers of value made by that entity to physicians and teaching hospitals (and additional categories of health care practitioners beginning with reports submitted on or after January 1, 2022). We also have similar reporting obligations with respect to financial interactions throughout the E.U. We expended significant efforts to establish, and are continuing to devote significant resources to



maintain and enhance, systems and processes in order to comply with these regulations. Requirements to track and disclose financial interactions with health care providers and organizations increase government and public scrutiny of these financial interactions. Failure to comply with the reporting requirements could result in significant civil monetary penalties.

The sales and marketing practices of our industry have been the subject of increased scrutiny from government authorities in the U.S. and other countries in which we market our products, and we believe that this trend will continue. Many of these laws have not been fully interpreted by the government authorities or the courts, and their provisions are subject to a variety of interpretations. While we have a corporate compliance program which, together with our policies and procedures, is designed to actively identify, prevent and mitigate risk through the implementation of compliance policies and systems and the promotion of a culture of compliance, if we are found not to be in full compliance with these laws and regulations, our business could be materially harmed. We may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from federal health care programs and/or the curtailment or restructuring of our operations. Even if we successfully defend against government challenge, responding to the challenge may cause us to incur significant legal expenses and divert our management's attention from the operation of our business.

If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other governmental pricing programs in the U.S., we could be subject to additional reimbursement requirements, penalties, sanctions and fines which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We participate in the Medicaid Drug Rebate Program, the 340B Drug Pricing Program, and a number of other federal and state government pricing programs in the U.S. in order to obtain coverage for our products by certain government health care programs. These programs would generally require us to pay rebates or provide discounts to certain private purchasers or government payers in connection with our products when dispensed to beneficiaries of these programs. In some cases, such as with the Medicaid Drug Rebate Program, the rebates are based on pricing and rebate calculations that we report on a monthly and quarterly basis to the government agencies that administer the programs. The terms, scope and complexity of these government pricing programs change frequently. We may also have reimbursement obligations or be subject to penalties if we fail to provide timely and accurate information to the government, pay the correct rebates or offer the correct discounted pricing. Changes to the price reporting or rebate requirements of these programs would affect our obligations to pay rebates or offer discounts. CMS recently proposed changes to the Medicaid Drug Rebate calculations to address treatment of value-based arrangements, accumulator adjustment programs implemented by payers, and new formulations of existing products. Responding to current and future changes to these and other Medicaid Rebate requirements may increase our costs and the complexity of compliance, will be time-consuming, and could have a material adverse effect on our results of operations.

If our processes and systems are not compliant with regulatory requirements, we could be subject to restrictions on marketing our products or could be delayed in submitting regulatory filings seeking approvals for our drug candidates.

We have a number of regulated processes and systems that are required both prior to and following approval of our drugs and drug candidates. These processes and systems are subject to continual review and periodic inspection by the FDA and other regulatory bodies. In addition, the clinical research organizations and other third parties that we work with in our non-clinical studies and clinical trials and our oversight of such parties are subject to similar reviews and periodic inspection by the FDA and other regulatory bodies. If compliance issues are identified at any point in the development and approval process, we may experience delays in filing for regulatory approval for our drug candidates, or delays in obtaining regulatory approval after filing, if at all. Any later discovery of previously unknown problems or safety issues with approved drugs or manufacturing processes, or failure to comply with regulatory requirements, may result in restrictions on such drugs or manufacturing processes, withdrawal of drugs from the market, the imposition of civil or criminal penalties or a refusal by the FDA and/or other regulatory bodies to approve pending applications for marketing approval of new drugs or supplements to approved applications, any of which could have a material adverse effect on our business. In addition, we are party to agreements that transfer responsibility for complying with specified regulatory requirements, such as filing and maintenance of marketing authorizations and safety reporting or compliance with manufacturing requirements, to our collaborators and third-party manufacturers. If our collaborators or third-party manufacturers do not fulfill these regulatory obligations, any drugs for which we or they obtain approval may be subject to later restrictions on manufacturing or sale, which could have a material adverse effect on our business.



We are subject to various and evolving laws and regulations governing the privacy and security of personal data, and our failure to comply could adversely affect our business, result in fines and/or criminal penalties, and damage our reputation.

We are subject to data privacy and security laws and regulations in various jurisdictions that apply to the collection, storage, use, sharing and security of personal data, including health information, and impose significant compliance obligations. In addition, numerous other federal and state laws, including state security breach notification laws, state health information privacy laws and federal and state consumer protection laws, govern the collection, use, disclosure and security of personal information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues with the potential to affect our business.

For example, the E.U. General Data Protection Regulation, or GDPR, went into effect in 2018 and has imposed new obligations on us with respect to our processing of personal data and the cross-border transfer of such data, including higher standards of obtaining consent, more robust transparency requirements, data breach notification requirements, requirements for contractual language with our data processors, and stronger individual data rights. Different E.U. member states have interpreted the GDPR differently and many have imposed additional requirements, which add to the complexity of processing personal data in the E.U. The GDPR also imposes strict rules on the transfer of personal data to countries outside the E.U., including the U.S., and permits data protection authorities to impose large penalties for violations of the GDPR. Compliance with the GDPR is a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection with any activities falling within the scope of the GDPR.

In the U.S., California has passed the California Consumer Privacy Act, which went into effect on January 1, 2020, and several states and the federal government are actively considering proposed legislation governing the protection of personal data. Additionally, Brazil passed the General Data Protection Law, or LGPD, which went into effect in August 2020. While we continue to address the implications of the new data privacy regulations, data privacy remains an evolving landscape at both the domestic and international level, with new regulations coming into effect and continued legal challenges. Each law is also subject to various interpretations by courts and regulatory agencies, creating even more uncertainty. While we have a global privacy program that addresses such laws and regulations, our efforts to comply with the evolving data protection rules may be unsuccessful.

We must devote significant resources to understanding and complying with the changing landscape in this area. Failure to comply with data protection laws may expose us to risk of enforcement actions taken by data protection authorities, private rights of action in some jurisdictions, and potential significant penalties if we are found to be non-compliant. Failure to comply with the GDPR and applicable national data protection laws of European Economic Area member states could lead to fines of up to €20,000,000 or up to 4% of the total worldwide annual revenue of the preceding financial year, whichever is higher. Some of these laws and regulations also carry the possibility of criminal sanctions. For example, while we are not directly subject to the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act, or HIPAA, we could be subject to penalties, including criminal penalties if we knowingly obtain or disclose individually identifiable health information from a HIPAA-covered health care provider or research institution that has not complied with HIPAA's requirements for disclosing such information. Furthermore, the number of government investigations related to data security incidents and privacy violations continue to increase and government investigations typically require significant resources and generate negative publicity, which could harm our business and our reputation.

The COVID-19 pandemic has added further complexity to the processing of personal data. For example, safety measures intended to protect our employees, contractors, and other visitors to our sites may require the collection of certain personal data. Although we are focused on ensuring that personal data is properly protected, our efforts may be unsuccessful and we could unintentionally be subject to unauthorized access or disclosure of such personal data.

Clinical Trial Regulation (EU) No. 536/2014, or the Clinical Trial Regulation, and the EMA policy on publication of clinical data for medicinal products for human use both permit the EMA to publish clinical information submitted in MAAs. This provision of the Clinical Trial Regulation is expected to be effective by the end of 2021. The ability of third parties to review and/or analyze data from our clinical trials may increase the risk of commercial confidentiality breaches and result in enhanced scrutiny of our clinical trial results. Such scrutiny could result in public misconceptions regarding our drugs and drug candidates. These publications could also result in the disclosure of information to our competitors that we might otherwise deem confidential, which could harm our business.



## If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our research and development efforts involve the regulated use of hazardous materials, chemicals and various controlled and radioactive compounds. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards prescribed by state, federal and foreign regulations, the risk of loss of, or accidental contamination or injury from, these materials cannot be eliminated. If an accident occurs, we could be held liable for resulting damages, which could be substantial. We also are subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of biohazardous materials. Although we maintain workers' compensation insurance to cover us for costs we may incur due to injuries to our employees resulting from the use of these materials, this insurance may not provide adequate coverage against potential liabilities. We maintain insurance to cover pollution conditions or other extraordinary or unanticipated events relating to our use and disposal of hazardous materials that we believe is appropriate based on the small amount of hazardous materials we generate. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of these laws or regulations.

## Risks Related to Business Development Activities

Our ability to execute on our long-term strategy depends in part on our ability to engage in transactions and collaborations with other entities that add to our pipeline or provide us with new commercial opportunities.

In order to achieve our long-term business objectives, we seek to license or acquire drugs, drug candidates and other technologies that have the potential to complement our ongoing research and development efforts, access emerging technologies and license or acquire pipeline assets. These transactions may be similar to prior transactions or may involve larger transactions or later-stage assets. We have faced and will continue to face significant competition for the acquisition of rights to these types of drugs, drug candidates and other technologies from a variety of other companies, many of which have significantly more financial resources and experience in business development activities than we have. In addition, non-profit organizations may be willing to provide capital to the companies that control additional drugs, drug candidates or technologies, which may provide incentives for companies to advance these drugs, drug candidates or technologies independently. Also, the cost of acquiring, in-licensing or otherwise obtaining rights to such drugs, drug candidates or other technologies has grown dramatically in recent years and may be at levels that we cannot afford or that we believe are not justified by market potential. As a result, we may not be able to acquire, in-license or otherwise obtain rights to additional drugs, drug candidates or other technologies on acceptable terms or at all.

We may not realize the anticipated benefits of acquisitions of businesses or technologies, and the integration following any such acquisition may disrupt our business and management.

It is challenging to effectively integrate businesses and technologies that we acquire, including the acquisitions of Semma and Exonics and the exclusive licenses that we have acquired from CRISPR and Moderna, and we may not realize the benefits anticipated from such transactions. Achieving the anticipated benefits of any transaction and successfully integrating acquired businesses or technologies involves a number of risks, including:

• failure to successfully develop and commercialize the acquired drugs, drug candidates or technologies or to achieve other strategic objectives;

- delays or inability to progress preclinical programs into clinical development or unfavorable data from clinical trials evaluating the acquired or licensed drug or drug candidates;

• difficulty in integrating the drugs, drug candidates, technologies, business operations and personnel of an acquired asset or company;

• disruption of our ongoing business and distraction of our management and employees from daily operations or other opportunities and challenges;

• the potential loss of key employees of an acquired company;



• entry into markets in which we have no or limited direct prior experience or where competitors in such markets have stronger market positions;

• potential failure of the due diligence processes to identify significant problems, liabilities or challenges of an acquired company, or acquired or licensed drug, drug candidate or technology, including but not limited to, problems, liabilities or challenges with respect to intellectual property, clinical or non-clinical data, safety, accounting practices, employee, or third-party relations and other known and unknown liabilities;

• liability for activities of the acquired company or licensor before the acquisition or license, including intellectual property infringement claims, violations of laws, commercial disputes, tax liabilities, and other known and unknown liabilities;

• exposure to litigation or other claims in connection with, or inheritance of claims or litigation risk as a result of an acquisition or license, including but not limited to, claims from terminated employees, customers, former equity holders or other third parties; and

• difficulties in the integration of the acquired company’s departments, systems, including accounting, human resource and other administrative systems, technologies, books and records, and procedures, as well as in maintaining uniform standards, controls, including internal control over financial reporting required by the Sarbanes-Oxley Act of 2002 and related procedures and policies.

Acquisitions, licensing arrangements and other strategic transactions are inherently risky, and ultimately, if we do not complete an announced acquisition, collaboration or strategic transaction or integrate an acquired or licensed asset, business or technology successfully and in a timely manner, we may not realize the anticipated benefits of the strategic transaction.

We may later incur impairment charges related to assets acquired in any such transaction. For example, we entered into a strategic collaboration and license agreement with Parion Sciences, Inc. to develop ENaC inhibitors in 2015 and incurred an impairment charge related to this collaboration in 2017. Even if we achieve the long-term benefits associated with our strategic transactions, our expenses and short-term costs may increase materially and adversely affect our liquidity and short-term net income. Future strategic transactions could result in potentially dilutive issuances of equity securities, the incurrence of debt, the creation of contingent liabilities, impairment expenses related to goodwill, or impairment or amortization expenses related to other intangible assets, all of which could harm our financial condition.

We face risks in connection with existing and future collaborations with respect to the development, manufacture and commercialization of our products and drug candidates.

The risks that we face in connection with our current collaborations, including CRISPR, and any future collaborations, include the following:

• Our collaborators may change the focus of their development and commercialization efforts or may have insufficient resources or expertise to effectively develop, manufacture or commercialize our drug candidates.

- The ability of some of our therapies to reach their potential could be limited if collaborators are unable to effectively develop, manufacture or commercialize these therapies or drug candidates or decrease or fail to increase development or commercialization efforts related to those therapies or drug candidates. Our collaboration agreements allocate development, manufacturing and commercialization responsibilities between us and our collaborators and provide our collaborators with a level of discretion in determining the amount and timing of efforts and resources that they will apply to these collaborations.

- Our collaborators may have limited experience in developing, manufacturing and commercializing therapies, either generally, or in the specific therapeutic area. For example, CRISPR, which is responsible for leading commercialization of CTX001 in the U.S., has no prior experience commercializing a therapy and is in the process of establishing the capabilities that would be required to commercialize CTX001 in the U.S.

- Collaboration agreements may have the effect of limiting the areas of research and development that we may pursue, either alone or in collaboration with third parties.



- Collaborators may develop and commercialize, either alone or with others, drugs that are similar to or competitive with the drugs or drug candidates that are the subject of their collaborations with us.

- Disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of development, might cause delays or termination of the research, development or commercialization of drug candidates, might lead to additional responsibilities or costs for us with respect to drug candidates, or might result in litigation or arbitration. Any such disagreements would divert management attention and resources and would be time-consuming and expensive.

- Collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation.

• Collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability.

- Investigations and/or compliance or enforcement actions against a collaborator, which may expose us to indirect liability as a result of our partnership with such collaborator.

• Our collaboration agreements are subject to termination under various circumstances.

Additionally, if a collaborator were to be involved in a business combination with a third party, it might de-emphasize or terminate the development or commercialization of any drug candidate licensed to it by us. If one of our collaborators terminates its agreement with us, we may find it more difficult to attract new collaborators and our perception in the business and financial communities could be harmed.

## We may not be able to attract collaborators or external funding for the development and commercialization of certain of our drug candidates.

As part of our ongoing strategy, we may seek additional collaborative arrangements or external funding for certain of our development programs and/or seek to expand existing collaborations to cover additional commercialization and/or development activities. We have a number of research programs and clinical development programs, some of which are being developed in collaboration with a third party. For example, we are co-developing CTX001, an investigational CRISPR/Cas9-based gene-editing therapy for SCD and TDT with our collaborator, CRISPR. At any time, we may determine that in order to continue development of a drug candidate or program or successfully commercialize a drug we need to identify a collaborator or amend or expand an existing collaboration. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator's resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator's evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA, EMA or other regulatory authorities, the potential market for the subject drug candidate, the costs and complexities of manufacturing and delivering such drug candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of the applicable intellectual property, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. Potentially, and depending on the circumstances, we may desire that a collaborator either agree to fund portions of a drug development program led by us, or agree to provide all of the funding and directly lead the development and commercialization of a program. No assurance can be given that any efforts we make to seek additional collaborative arrangements will be successfully completed on a timely basis or at all. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we are unable to enter into acceptable collaborative relationships, one or more of our development programs could be delayed or terminated and the possibility of our receiving a return on our investment in the program could be impaired.



## Risks Related to Third-Party Manufacturing and Reliance on Third Parties

We depend on third-party manufacturers to manufacture our products and the materials we require for our clinical trials. We may not be able to maintain these relationships and could experience supply disruptions outside of our control.

We rely on a worldwide network of third-party manufacturers to manufacture our drugs for commercial use and our drug candidates for clinical trials. As a result of our reliance on these third-party manufacturers and suppliers, we could be subject to significant supply disruptions outside of our control. Our supply chain for sourcing raw materials and manufacturing drug product ready for distribution is a multi-step international endeavor. Third-party contract manufacturers, including some in China, perform different parts of our manufacturing process. Contract manufacturers may supply us with raw materials, convert these raw materials into drug substance and/or convert the drug substance into final dosage form. Third parties are used for packaging, warehousing and distribution of products. In cell and genetic therapies, third parties also will be used to both manufacture and deliver our therapies, which requires significant expertise.

Establishing, managing and expanding this global supply chain requires a significant financial commitment and the creation and maintenance of numerous third-party contractual relationships. Although we attempt to manage the business relationships with companies in our supply chain, we could be subject to supply disruptions outside of our control. For example, we are collaborating with CRISPR on establishing the supply chain to support clinical trials and commercial supply for CTX001, if approved. As a result, we do not have independent control over the related supply operations and are reliant on CRISPR to adequately establish the corresponding supply chains.

Supply disruptions may result from a number of factors, including shortages in product raw materials, labor or technical difficulties, regulatory inspections or restrictions, shipping or customs delays or any other performance failure by any third-party manufacturer on which we rely. Any supply disruptions could disrupt sales of our products and/or the timing of our clinical trials.

We require a supply for our medicines for commercial sale and a supply of our drug candidates for use in our clinical trials. While we have developed some internal capabilities, a majority of the manufacturing steps needed to produce our drug candidates and drug products are performed through a third-party manufacturing network. To ensure the stability of our supply chains, we aim to develop additional sources of manufacture for all steps of our manufacturing processes at the time of, or shortly after, marketing approval. Therefore, at any point in time, we may have a limited number of single source manufacturers for certain steps in our manufacturing processes, particularly for recently launched products.

If we or our third-party manufacturers become unable or unwilling to continue manufacturing product and we are not able to promptly identify another manufacturer, we could experience a disruption in the commercial supply of our then-marketed medicines, which would have a significant effect on patients, our business and our product revenues. Similarly, a disruption in the clinical supply of drug products could delay the completion of clinical trials and affect timelines for regulatory filings. There can be no assurance that we will be able to establish and maintain additional manufacturers for all of our drug candidates and drug products on a timely basis or at all.

In the course of providing its services, a contract manufacturer may develop process technology related to the manufacture of our products or drug candidates that the manufacturer owns, either independently or jointly with us. This would increase our reliance on that manufacturer or require us to obtain a license from that manufacturer in order to have our products or drug candidates manufactured by other suppliers utilizing the same process.

We rely on third parties to conduct pre-clinical work, clinical trials and other activities, and those third parties may not perform satisfactorily, including failing to meet established deadlines for the completion of such studies and/or trials or failing to satisfy regulatory requirements.

We rely on third parties such as contract research organizations to help manage certain pre-clinical work and our clinical trials and on medical institutions, clinical investigators and clinical research organizations such as the Therapeutic Development Network, which is primarily funded by the CFF, to assist in the design and review of, and to conduct our clinical trials, including enrolling qualified patients. In addition, we engage third party contractors to support numerous other research, commercial and administrative activities. Our reliance on these third parties for clinical development activities reduces our control over these activities but does not relieve us of our responsibilities. For example, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the clinical trial. Moreover, the FDA requires us to comply with standards, commonly referred to as good laboratory practices.



and good clinical practices, for conducting, recording and reporting the results of pre-clinical and clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Such standards, particularly with respect to newer cell and genetic therapies, will continue to evolve and subject us and third parties to new or changing requirements.

If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be required to replace them. Although we believe that there are a number of other third-party contractors we could engage to continue the activities, it may result in a delay of the affected clinical trial, drug development program or applicable activity. If clinical trials are not conducted in accordance with our contractual expectations or regulatory requirements, action by regulatory authorities might significantly and adversely affect the conduct or progress of these clinical trials or in specific circumstances might result in a requirement that a clinical trial be redone. Accordingly, our efforts to obtain regulatory approvals for and commercialize our drug candidates could be delayed. In addition, failure of any third party contractor to conduct activities in accordance with our expectations could adversely affect the relevant research, development, commercial or administrative activity.

## Risks Related to Intellectual Property

If our patents do not protect our drugs or our drugs infringe third-party patents, we could be subject to litigation which could result in injunctions preventing us from selling our products or substantial liabilities.

We have numerous issued patents and pending patent applications in the U.S., as well as counterparts in other countries. Our success will depend, in significant part, on our ability to obtain and defend U.S. and foreign patents covering our drugs, their uses and our processes, to preserve our trade secrets and to operate without infringing the proprietary rights of third parties. We cannot be certain that any patents will issue from our pending patent applications or, even if patents issue or have issued, that the issued claims will provide us with adequate protection against competitive products or otherwise be commercially valuable.

Due to evolving legal standards relating to the patentability, validity and enforceability of patents covering pharmaceutical inventions and the scope of claims made under these patents, our ability to obtain, maintain and enforce patents is uncertain and involves complex legal and factual questions. Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents in the U.S. The Leahy-Smith America Invents Act, or the Leahy-Smith Act, includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. The U.S. Patent Office developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, became effective in March 2013. The first to file provisions limit the rights of an inventor who is the first to invent an invention but is not the first to file an application claiming that invention. U.S. and foreign patent applications typically are maintained in confidence for a period of time after they initially are filed with the applicable patent office. Consequently, we cannot be certain that we were the first to invent, or the first to file patent applications on, our products or drug candidates or their use. If a third party also has filed a U.S. patent application relating to our drugs or drug candidates, their uses, or a similar invention, we may have to participate in legal or administrative proceedings to determine priority of invention. For applications governed by the Leahy-Smith Act, if a third-party has an earlier filed U.S. patent application relating to our drugs or drug candidates, their uses, or a similar invention, we may be unable to obtain an issued patent from our application.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability. Our patents may be challenged by third parties and certain of our patents have been challenged in the past. This could result in the patent being deemed invalid, unenforceable or narrowed in scope, or the third party may circumvent any such issued patents. Also, our pending patent applications may not issue, and we may not receive any additional patents.

Our patents or patents we license might not contain claims that are sufficiently broad to prevent others from developing competing products. For instance, issued patents, or patents that may issue in the future, (i) relating to our small molecules may be limited to a particular molecule or molecules and may not cover similar molecules that have similar clinical properties, and (ii) relating to cell or genetic therapies may not cover similar technologies that would allow competitors to achieve similar results. Consequently, our competitors may independently develop competing products that do not infringe our patents or other intellectual property. In addition, CRISPR only has non-exclusive or co-exclusive rights to the patent rights that protect the core CRISPR/Cas9 gene-editing technology.



The laws of many foreign jurisdictions do not protect intellectual property rights to the same extent as in the U.S. and many companies in our segment of the pharmaceutical industry have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such difficulties in protecting or are otherwise precluded from effectively protecting our intellectual property rights in foreign jurisdictions, our business could be substantially harmed.

Because of the extensive time required for the discovery, development, testing and regulatory review of drug candidates, it is possible that a patent may expire before a drug candidate can be commercialized, or a patent may expire or remain in effect for only a short period following commercialization of such drug candidate. This would result in a minimal or non-existent period of patent exclusivity. If our drug candidates are not commercialized significantly ahead of the expiration date of any applicable patent, or if we have no patent protection on such drug candidates, then, to the extent available we would rely on other forms of exclusivity, such as regulatory exclusivity provided by the FDCA and its counterpart agencies in various jurisdictions, and/or orphan drug exclusivity.

Uncertainty over intellectual property in the pharmaceutical and biotechnology industry has been the source of litigation and other disputes, which is inherently costly and unpredictable.

There is considerable uncertainty within our industry about the validity, scope and enforceability of many issued patents in the U.S. and elsewhere in the world, and, to date, the law and practice remains in substantial flux both in the agencies that grant patents and in the courts. We cannot currently determine the ultimate scope and validity of patents which may be granted to third parties in the future or which patents might be asserted as being infringed by the manufacture, use and sale of our products.

There has been, and we expect that there may continue to be, significant litigation in the pharmaceutical industry regarding patents and other intellectual property rights. Litigation, arbitrations, administrative proceedings and other legal actions with private parties and governmental authorities concerning patents and other intellectual property rights may be protracted, expensive and distracting to management. Competitors may sue us as a way of delaying the introduction of our drugs or to remove our drugs from the market. Any litigation, including litigation related to Abbreviated New Drug Applications, or ANDA, litigation related to 505(b)(2) applications, interference proceedings to determine priority of inventions, derivations proceedings, inter partes review, oppositions to patents in foreign countries, litigation against our collaborators or similar actions, may be costly and time consuming and could harm our business. We expect that litigation may be necessary in some instances to determine the validity and scope of certain of our proprietary rights. Litigation may be necessary in other instances to determine the validity, scope or non-infringement of certain patent rights claimed by third parties to be pertinent to the manufacture, use or sale of our products. Ultimately, the outcome of such litigation could adversely affect the validity and scope of our patent or other proprietary rights, hinder our ability to manufacture and market our products, or result in the assessment of significant monetary damages against us that may exceed amounts, if any, accrued in our consolidated financial statements.

On July 24, 2020, we filed a lawsuit against Sun Pharmaceutical Industries Limited, or Sun, in the U.S. District Court for the District of Delaware alleging infringement of U.S. Patent No. 10,646,481, or the '481 patent. The lawsuit follows Vertex's receipt of a Notice Letter on June 11, 2020, advising that Sun had submitted an ANDA to the FDA seeking approval to manufacture and market a generic version of the 150 mg tablet of KALYDECO in the U.S. The Notice Letter indicated that Sun submitted a "Paragraph IV" certification to the FDA in which Sun asserted that the '481 patent is invalid or would not be infringed by Sun's generic product. The '481 patent, which expires in 2029, was issued on May 12, 2020, and listed in the Orange Book with respect to KALYDECO 150 mg tablets on June 1, 2020. Sun does not appear to challenge our other U.S. patents covering KALYDECO. Vertex intends to vigorously enforce its intellectual property rights relating to KALYDECO, including the '481 patent.

CRISPR has licensed certain rights to a worldwide patent portfolio that covers various aspects of the CRISPR/Cas9 editing platform technology including, for example, compositions of matter and methods of use, including their use in targeting or cutting DNA from Dr. Charpentier, one of the named inventors of this patent portfolio. The patent portfolio also has named inventors who assigned their rights either to the Regents of the University of California or the University of Vienna, to whom we refer, together with Dr. Charpentier, as the CVC Group. For example, in connection with their collaboration, Novartis and Intellia Therapeutics, Inc. have obtained a license to this patent portfolio in certain fields. Patents and patent applications in this patent portfolio have been the subject of numerous contentious proceedings in the U.S., Europe, and other jurisdictions, including interference proceedings between the CVC and the Broad Institute in the USPTO. Decisions rendered to date in these proceedings may be subject to appeal. To date, both the CVC and the Broad have obtained granted patents that purport to cover aspects of CRISPR/Cas9 editing platform technology. The patents and patent



applications within the CVC patent portfolio and the Broad patent portfolio are, or may in the future be, involved in proceedings similar to interferences or priority disputes in Europe or other foreign jurisdictions. We can give no assurances to the ultimate outcome of these proceedings or the dispute between the CVC Group and Broad.

In addition to the Broad, other third parties have filed patent applications claiming CRISPR/Cas9-related inventions and may allege that they invented one or more of the inventions claimed by the CVC Group. Thus, the USPTO may, in the future, declare an interference between certain CVC Group patent applications and one or more patent applications. The Broad, as well as other third parties, could seek to assert its issued patents against us based on our CRISPR/Cas9-based activities, including commercialization. Defense of these claims, regardless of their merit, could involve substantial litigation expense and could result in a substantial diversion of management and other employee resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, obtain one or more licenses from third parties, pay royalties or redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. In that event, we could be unable to further develop and commercialize CTX001 or other products that we may develop using the CRISPR/Cas9 technology we license from CRISPR.

To the extent that valid present or future third-party patents or other intellectual property rights cover our drugs, drug candidates or technologies, we or our strategic collaborators may seek licenses or other agreements from the holders of such rights in order to avoid or settle legal claims. Such licenses may not be available on acceptable terms, which may hinder our ability to, or prevent us from being able to, manufacture and market our drugs. Payments under any licenses that we are able to obtain would reduce our profits derived from the covered products.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these employees or we have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee’s former employer. Litigation may be necessary to defend against these claims.

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to management.

## Risks Related To Our Operations

## Risks associated with operating in foreign countries could materially adversely affect our business.

We have expanded our international operations over the past several years in order to market our CF medicines and expand our research and development capabilities. New laws and industry codes in the E.U. and elsewhere have expanded transparency requirements regarding payments and transfers of value to healthcare professionals, requirements surrounding patient-level clinical trial data, the protection of personal data and increased sanctions for violations. Collectively, our expansion and these new requirements are adding to our compliance costs and potentially exposes us to sanctions in the event of an infringement or failure to report in these jurisdictions. In addition, a significant portion of our commercial supply chain, including sourcing of raw materials and manufacturing, is located in China and the E.U. Consequently, we are, and will continue to be, subject to risks related to operating in foreign countries, including risks relating to intellectual property protections and business interruptions. These risks are increased with respect to countries such as China that have substantially different local laws and business practices and weaker protections for intellectual property. Risks associated with operating a global biotechnology company include:

• differing regulatory requirements for drug approvals and regulation of approved drugs in foreign countries;



• varying reimbursement regimes and difficulties or the inability to obtain reimbursement for our products in foreign countries in a timely manner;

• differing patient treatment infrastructures, particularly since our business is focused on the treatment of serious diseases that affect relatively smaller numbers of patients and are typically prescribed by specialist physicians;

• collectability of accounts receivable;

• changes in tariffs, trade barriers and regulatory requirements, the risks of which appear to have increased in the current political environment;

• economic weakness, including recession and inflation, or political instability in particular foreign economies and markets;

• differing levels of enforcement and/or recognition of contractual and intellectual property rights;

• complying with local laws and regulations, which can change significantly over time;

• foreign taxes, including withholding of payroll taxes;

- foreign currency fluctuations, which could result in reduced revenues or increased operating expenses, and other obligations incident to doing business or operating in another country;

• workforce uncertainty in countries where labor unrest is more common than in the U.S.;

• reliance on third-party vendors and suppliers;

• import and export licensing requirements, tariffs, and other trade and travel restrictions;

• global or regional public health emergencies that could affect our operations or business;

• production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

• business interruptions resulting from geo-political actions, including war and terrorism.

Our revenues are subject to foreign exchange rate fluctuations due to the global nature of our operations. Although we have foreign currency forward contracts to hedge forecasted product revenues denominated in foreign currencies, our efforts to reduce currency exchange losses may not be successful. As a result, currency fluctuations among our reporting currency, the U.S. dollar, and the currencies in which we do business will affect our operating results, often in unpredictable ways.

In addition, our international operations are subject to regulation under U.S. law. For example, the FCPA prohibits U.S. companies and their representatives from offering, promising, authorizing or making payments to foreign officials for the purpose of obtaining or retaining business abroad. In many countries, the health care professionals we regularly interact with may meet the definition of a foreign government official for purposes of the FCPA. We also are subject to import/export control laws. Failure to comply with domestic or foreign laws could result in various adverse consequences, including the possible delay in approval or refusal to approve a product, recalls, seizures, withdrawal of an approved product from the market, the imposition of civil or criminal sanctions, the prosecution of executives overseeing our international operations and corresponding bad publicity and negative perception of our company in foreign countries.

## We are subject to risks associated with the global COVID-19 pandemic.

The COVID-19 pandemic has broadly affected the global economy, resulted in significant travel and work restrictions in many regions and has put a significant strain on healthcare resources. COVID-19 has had, and we expect it will continue to have, an impact on our operations, an impact on the operations of our collaborators, third-party contractors and other entities, including governments, governmental agencies and payors, with which we interact, and an impact on the people with CF who take our medicines. To date, the most significant effect on our business operations has been the requirement that a majority of our employees work remotely. We have re-initiated enrollment and dosing in all of our ongoing clinical trials and initiated new clinical trials despite some temporary pauses to enrollment and dosing early in the pandemic.



We continue to monitor local COVID-19 trends and government guidance for each of our site locations and are utilizing a phased, site-specific approach to assess employee access to our sites. Currently, all of our research and manufacturing sites are open to essential employees. There can be no assurance that our sites will remain open, when additional employees will gain access to our sites or whether we will be required to pause enrollment and dosing at clinical trial sites. Any site closure or pause of a clinical trial could harm our operations and delay the development of our product candidates. In addition, even if sites or clinical trials are open for enrollment, COVID-19 may nevertheless impact clinical trial enrollment or participation, for example due to suspension of in-person procedures required for enrollment, government shut-down orders, or decreased patient willingness to participate compared to pre-COVID-19 pandemic levels. COVID-19 may also impact uptake of our medicines generally and patient retention in clinical trials, potentially resulting in higher drop-out rates or missed visits, which may negatively affect the strength of our clinical trial data.

In the future, the economic impacts of the COVID-19 pandemic could affect our business directly or indirectly, including potentially affecting the net prices for our products through changes in our payor mix as a result of increased unemployment in the U.S. or increased pressure on healthcare costs in the U.S. and around the world. The effects on our research, development, manufacturing and commercialization activities, including the virtual launch of KAFTRIO in the E.U., will be dependent on, among other things, the severity and duration of the COVID-19 pandemic and any worsening of the global economic environment as a result thereof, as well as the impact of the pandemic on our third-party manufacturers, suppliers, distributors, subcontractors and customers. While the ultimate impact of COVID-19 on our business is highly uncertain, any negative impacts that materialize could materially adversely affect our operations, financial performance and stock price. Any negative impacts of COVID-19, alone or in combination with others, could exacerbate other risk factors discussed herein. The full extent to which the COVID-19 pandemic will negatively affect our operations, financial performance and stock price will depend on future developments that are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

## If we fail to manage our operations effectively, our business may suffer.

We have expanded and are continuing to expand our global operations and capabilities, which has placed, and will continue to place, significant demands on our management and our operational, research and development and financial infrastructure. To effectively manage our business, we need to:

• implement and clearly communicate our corporate-wide strategies;

• enhance our operational and financial infrastructure, including our controls over records and information;

• enhance our operational, financial and management processes, including our cross-functional decision-making processes and our budget prioritization systems;

• train and manage our global employee base; and

• enhance our compliance and legal resources.

## If we fail to attract and retain skilled employees, our business could be materially harmed.

Due to the highly technical nature of our drug discovery and development activities, we require the services of highly qualified and trained scientists who have the skills necessary to conduct these activities. In addition, we need to attract and retain employees with experience in marketing and commercialization of medicines. We have entered into employment agreements with some executives and provide stock-related compensation benefits to all of our key employees that vest over time and therefore induce them to remain with us. However, the employment agreements can be terminated by the executive on relatively short notice. The value to employees of stock-related benefits that vest over time - such as restricted stock units and stock options - can be significantly affected by movements in our stock price, and may, at any point in time, be insufficient to counteract more lucrative offers from other companies. We face intense competition for our personnel from our competitors and other companies throughout our industry, especially with respect to employees with expertise in cell or genetic therapies. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. Moreover, the growth of local biotechnology companies and the expansion of major pharmaceutical companies into the Boston area has increased competition for the available pool of skilled employees, especially in technical fields. The high cost of living can make it difficult to attract employees from other parts of the country to our Massachusetts headquarters. In addition, the available pool of skilled employees would be further reduced if immigration laws change in a manner that increases restrictions on immigration. Our ability to continue to commercialize our products and achieve our



research and development objectives depends on our ability to respond effectively to these demands. If we are unable to hire and retain qualified personnel, there could be a material adverse effect on our business.

## Our business faces potential risks relating to the United Kingdom’s withdrawal from the European Union.

Our European headquarters and European research facility are located in the U.K., and a significant portion of our ex-U.S. net product revenues are derived from sales in the U.K. On January 31, 2020, the U.K. formally withdrew from the E.U., also known as Brexit. The U.K. and the E.U. negotiated a detailed post-Brexit Trade and Cooperating Agreement which went into effect on January 1, 2021. As of January 1, 2021, E.U. Treaties, E.U. free movement rights and the general principals of E.U. law no longer apply in relation to the U.K. By virtue of the E.U. (Withdrawal) Act 2018, E.U. relations will continue to apply in U.K. domestic law to the extent that they are not modified or revoked by regulations under that Act. Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate. Given the lack of comparable precedent, it is unclear what financial, trade, regulatory and legal implications the withdrawal of the U.K. from the E.U. would have and how such withdrawal would affect us. Any of these effects of Brexit, among others, could adversely affect our business, financial condition and operating results.

## Our business has a substantial risk of product liability claims and other litigation liability.

We are or may be involved in various legal proceedings, including securities/shareholder matters and claims related to product liability, intellectual property and breach of contract. Such proceedings may involve claims for, or the possibility of, damages or fines and penalties involving substantial amounts of money or other relief, including but not limited to civil or criminal fines and penalties. If any of these legal proceedings were to result in an adverse outcome, it could have a material adverse effect on our business.

With respect to product liability and clinical trial risks, in the ordinary course of business we are subject to liability claims and lawsuits, including potential class actions, alleging that our products or drug candidates have caused, or could cause, serious adverse events or other injury. We have product liability insurance and clinical trial insurance in amounts that we believe are adequate to cover this risk. However, our insurance may not provide adequate coverage against all potential liabilities. If a claim is brought against us, we might be required to pay legal and other expenses to defend the claim, as well as pay uncovered damage awards resulting from a claim brought successfully against us and these damages could be significant and have a material adverse effect on our financial condition. Furthermore, whether or not we are ultimately successful in defending any such claims, we might be required to direct significant financial and managerial resources to such defense and adverse publicity is likely to result.

## A breakdown or breach of our information technology systems could subject us to liability or interrupt the operation of our business.

We maintain and rely extensively on information technology systems and network infrastructures for the effective operation of our business. In the course of our business, we collect, store and transmit confidential information (including personal information and intellectual property), and it is critical that we do so in a secure manner to maintain the confidentiality and integrity of such confidential information. The size and complexity of our information technology and information security systems makes such systems potentially vulnerable to service interruptions and to security breaches. A disruption, infiltration or failure of our information technology systems or any of our data centers as a result of software or hardware malfunctions, computer viruses, cyber-attacks, employee theft or misuse, power disruptions, natural disasters, floods or accidents could cause breaches of data security and loss of critical data, which in turn could materially adversely affect our business and subject us to both private and governmental causes of action. While we have implemented security measures in an attempt to minimize these risks to our data and information technology systems and have adopted a business continuity plan to deal with a disruption to our information technology systems, cyber-attacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult to detect. There can be no assurance that our efforts to protect our data and information systems will prevent breakdowns or breaches in our systems that could adversely affect our business. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to security breaches, cyber-attacks or other related liabilities.

Risk of cyber-attack is increased with the majority of employees working remotely during the ongoing COVID-19 pandemic. During this time, there is an increased risk that we may be vulnerable to cybersecurity-related events such as phishing attacks and other security threats as a result of our employees, third party vendors and collaborators working remotely from non-corporate managed networks.



## If our facilities were to experience a catastrophic loss, our operations would be seriously harmed.

Most of our operations, including our research and development activities, are conducted in a limited number of facilities. If any of our major facilities were to experience a catastrophic loss, due to an earthquake, severe storms, fire or similar event, our operations could be seriously harmed. For example, our corporate headquarters, as well as additional leased space that we use for certain logistical and laboratory operations and manufacturing, are located in a flood zone along the Massachusetts coast. We have adopted a business continuity plan to address most crises. However, if we are unable to fully implement our business continuity plans, we may experience delays in recovery of data and/or an inability to perform vital corporate functions, which could result in a significant disruption in our research, development, manufacturing and/or commercial activities, large expenses to repair or replace the facility and/or the loss of critical data, which could have a material adverse effect on our business.

## The use of social media platforms presents risks and challenges.

Social media is being used by third parties to communicate about our products and drug candidates and the diseases our therapies are designed to treat. We believe that members of the CF community may be more active on social media as compared to other patient populations due to the demographics of this patient population. Social media practices in the pharmaceutical and biotechnology industries are evolving, which creates uncertainty and risk of noncompliance with regulations applicable to our business. For example, patients may use social media platforms to comment on the effectiveness of, or adverse experiences with, a drug or a drug candidate, which could result in reporting obligations. In addition, our employees may engage on social media in ways that may not comply with legal or regulatory requirements, which may give rise to liability, lead to the loss of trade secrets and other intellectual property, or result in public disclosure of protected personal information. There is a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social networking website. Certain data protection regulations, such as the GDPR, apply to personal data contained on social media. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face regulatory actions or incur harm to our business, including damage to our reputation.

## Risks Related to Financial Results and Holding Our Common Stock

## Our stock price may fluctuate.

Market prices for securities of companies such as ours are highly volatile. From January 1, 2020 to December 31, 2020, our common stock traded between $197.47 and $306.08 per share. The market for our stock, like that of other companies in the biotechnology industry, has experienced significant price and volume fluctuations. The future market price of our securities could be significantly and adversely affected by factors such as:

- the information contained in our quarterly earnings releases, including our net product revenues and operating expenses for completed periods and guidance regarding future periods;

• announcements of FDA actions with respect to our therapies or those of our competitors, or regulatory filings for our therapies or those of our competitors, or announcements of interim or final results of clinical trials or nonclinical studies relating to our therapies or those of our competitors;

• developments in domestic and international governmental policy or regulation, for example, relating to drug pricing or intellectual property rights;

• technological innovations or the introduction of new drugs by our competitors;

• government regulatory action;

• public concern as to the safety of drugs developed by us or our competitors;

• developments in patent or other intellectual property rights or announcements relating to these matters;

• information disclosed by third parties regarding our business or products;

• developments relating specifically to other companies and market conditions for pharmaceutical and biotechnology stocks or stocks in general;



• business development, capital structuring or financing activities; and

• general worldwide or national economic, political and capital market conditions, including as a result of the ongoing COVID-19 pandemic.

Following periods of volatility in the market price of a company’s securities, stockholder derivative lawsuits and securities class action litigation are common. Such litigation, if instituted against us or our officers and directors, could result in substantial costs and a diversion of management’s attention and resources.

## Our quarterly operating results are subject to significant fluctuation.

Our operating results have fluctuated from quarter to quarter in the past, and we expect that they will continue to do so in the future. Our revenues are primarily dependent on the level of net product revenues from sales of our CF medicines. Our total net product revenues could vary on a quarterly basis based on, among other factors, the timing of orders from our significant customers. Additional factors that have caused quarterly fluctuations to our operating results in recent years include variable amounts of revenues, expenses related to business development activities, changes in the fair value of our strategic investments, impairment charges, charges for excess and obsolete inventories, changes in the fair value of derivative instruments and the consolidation or deconsolidation of variable interest entities. Our revenues also are subject to foreign exchange rate fluctuations due to the global nature of our operations. Although we have foreign currency forward contracts to hedge forecasted product revenues denominated in foreign currencies, our efforts to reduce currency exchange losses may not be successful. As a result, currency fluctuations among our reporting currency, the U.S. dollar, and the currencies in which we do business may affect our operating results, often in unpredictable ways. Our quarterly results also could be materially affected by significant charges, which may or may not be similar to charges we have experienced in the past. Most of our operating expenses relate to our research and development activities, do not vary directly with the amount of revenues and are difficult to adjust in the short term. As a result, if revenues in a particular quarter are below expectations, we are unlikely to reduce operating expenses proportionately for that quarter. These examples are only illustrative and other risks, including those discussed in these “Risk Factors,” could also cause fluctuations in our reported financial results. Our operating results during any one period do not necessarily suggest the results of future periods.

We expect that results from our clinical development activities and the clinical development activities of our competitors will continue to be released periodically, and may result in significant volatility in the price of our common stock.

Any new information regarding our products and drug candidates or competitive products or potentially competitive drug candidates can substantially affect investors' perceptions regarding our future prospects. We, our collaborators and our competitors periodically provide updates regarding drug development programs, typically through press releases, conference calls and presentations at medical conferences. These periodic updates often include interim or final results from clinical trials conducted by us or our competitors and/or information about our or our competitors' expectations regarding regulatory filings and submissions as well as future clinical development of our products or drug candidates, competitive products or potentially competitive drug candidates. The timing of the release of information by us regarding our drug development programs is often beyond our control and is influenced by the timing of receipt of data from our clinical trials and by the general preference among pharmaceutical companies to disclose clinical data during medical conferences. In addition, the information disclosed about our clinical trials, or our competitors' clinical trials, may be based on interim rather than final data that may involve interpretation difficulties and may in any event not accurately predict final results. The release of such information may result in volatility in the price of our common stock.

## Changes in tax laws, regulations and treaties could affect our future taxable income.

We are subject to taxation in numerous countries, states and other jurisdictions. As a result, our effective tax rate is derived from a combination of applicable tax rates in the various places that we operate globally. Our effective tax rate may be different than experienced in the past due to numerous factors, including changes in the mix of our profitability from country to country, the results of tax authority examinations/audits of our tax filings, adjustments to the value of our uncertain tax positions, changes in accounting for income taxes and changes in tax laws or modifications of treaties in various jurisdictions. For example, changes to the U.S. tax code are anticipated under the new administration. Any of these factors could cause us to experience an effective tax rate that is significantly different from previous periods or our current expectations.



We continue to assess the impact of various tax reform proposals and modifications to existing tax treaties in all jurisdictions where we have operations to determine the potential effect on our business and any assumptions we have made about our future taxable income. We cannot predict whether any specific proposals will be enacted, the terms of any such proposals or what effect, if any, such proposals would have on our business if they were to be enacted.

Recommendations from the Organization for Economic Co-operation and Development that are part of the base erosion and profit shifting, or BEPS, framework could result in changes in tax laws in countries where we do business and adversely affect our provision for income taxes and our current rate. If these recommendations (or other changes in law) were adopted by the countries in which we do business, it could adversely affect our provision for income tax and our current rate.

## General Risk Factors

## We may need to raise additional capital that may not be available.

We may need to raise additional capital in the future. Any potential public offering, private placement or debt financing may or may not be similar to the transactions that we entered into in the past. Any debt financing may be on terms that, among other things, include conversion features that could result in dilution to our then-existing security holders and restrict our ability to pay interest and dividends—although we do not intend to pay dividends for the foreseeable future. Any equity financings would result in dilution to our then-existing security holders. If adequate funds are not available on acceptable terms, or at all, we may be required to curtail significantly or discontinue one or more of our research, drug discovery or development programs, including clinical trials, incur significant cash exit costs, or attempt to obtain funds through arrangements with collaborators or others that may require us to relinquish rights to certain of our technologies, drugs or drug candidates. Based on many factors, including general economic conditions, additional financing may not be available on acceptable terms, if at all.

Future indebtedness could materially and adversely affect our financial condition, and the terms of our credit agreements impose restrictions on our business, reducing our operational flexibility and creating default risks.

In 2019, we entered into a credit agreement providing for a $500 million revolving facility. In September 2020, we entered into a second credit agreement providing for a $2.0 billion revolving facility. Each of the credit agreements provides that, subject to the satisfaction of certain conditions, we may request the borrowing capacity be increased by an additional $500.0 million. If we borrow under our current credit agreements or any future credit agreement, such indebtedness could have important consequences to our business, including increasing our vulnerability to general adverse financial, business, economic and industry conditions, as well as other factors that are beyond our control. The credit agreements require that we comply with certain financial covenants, including (i) a consolidated leverage ratio covenant and (ii) a consolidated interest coverage ratio covenant, in each case to be measured on a quarterly basis. Further, the credit agreements include negative covenants, subject to exceptions, restricting or limiting our ability and the ability of our subsidiaries to, among other things, incur additional indebtedness, grant liens, engage in certain investment, acquisition and disposition transactions, pay dividends, repurchase capital stock and enter into transactions with affiliates. As a result, we may be restricted from engaging in business activities that may otherwise improve our business. Failure to comply with the covenants could result in an event of default that could trigger acceleration of our indebtedness, which would require us to repay all amounts owing under the credit agreements and/or our finance leases and could have a material adverse effect on our business. Additionally, our obligations under the credit agreements are unconditionally guaranteed by certain of our domestic subsidiaries.

## Issuances of additional shares of our common stock could cause the price of our common stock to decline.

As of December 31, 2020, we had 259.9 million shares of common stock issued and outstanding. As of December 31, 2020, we also had outstanding options to purchase 4.2 million shares of common stock with a weighted-average exercise price of $140.47 per share. Outstanding vested options are likely to be exercised if the market price of our common stock exceeds the applicable exercise price, and, in the future, we expect to issue additional equity awards to directors and employees. In addition, we may issue additional common stock or restricted securities in the future as part of financing activities or business development activities and any such issuances may have a dilutive effect on our then-existing shareholders. Sales of substantial amounts of our common stock in the open market, or the availability of such shares for sale, could adversely affect the price of our common stock. The issuance of restricted common stock or common stock upon exercise of any outstanding options would be dilutive, and may cause the market price for a share of our common stock to decline.



## There can be no assurance that we will repurchase shares of common stock or that we will repurchase shares at favorable prices.

In November 2020, our Board of Directors authorized a share repurchase program pursuant to which we are authorized to repurchase up to $500 million of our common stock by December 31, 2022. As of December 31, 2020, we had repurchased $75.1 million of common stock under the share repurchase program and had remaining available $424.9 million to repurchase additional shares pursuant to this program.

Our stock repurchases will depend upon, among other factors, our cash balances and potential future capital requirements, results of operations, financial condition and other factors that we may deem relevant. We can provide no assurance that we will repurchase stock at favorable prices, if at all.

We have adopted anti-takeover provisions and are subject to Massachusetts corporate laws that may frustrate any attempt to remove or replace our current management or effectuate a business combination involving Vertex.

Our corporate charter and by-law provisions and Massachusetts state laws may discourage certain types of transactions involving an actual or potential change of control of Vertex that might be beneficial to us or our security holders. Our by-laws grant the directors a right to adjourn annual meetings of shareholders, and certain provisions of our by-laws may be amended only with an 80% shareholder vote. We may issue shares of any class or series of preferred stock in the future without shareholder approval and upon such terms as our Board of Directors may determine. The rights of the holders of common stock will be subject to, and may be adversely affected by, the rights of the holders of any class or series of preferred stock that may be issued in the future. Massachusetts state law prohibits us from engaging in specified business combinations, unless the combination is approved or consummated in a prescribed manner, and prohibits voting by any shareholder who acquires 20% or more of our voting stock without shareholder approval. As a result, shareholders or other parties may find it more difficult to remove or replace our current management.

## ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

## OVERVIEW

We invest in scientific innovation to create transformative medicines for people with serious diseases with a focus on specialty markets. We have four approved medicines to treat cystic fibrosis, or CF, a life-threatening genetic disease, and we are focused on increasing the number of patients eligible and able to receive our current medicines through label expansions, approval of new medicines and expanded reimbursement. We are broadening our pipeline into additional disease areas through internal research efforts and accessing external innovation through business development transactions.

Our triple combination regimen, TRIKAFTA/KAFTRIO, was approved in 2019 in the United States, or U.S., and in 2020 in the European Union, or E.U. Collectively, our four medicines are approved to treat the majority of the approximately 83,000 people with CF in North America, Europe and Australia. We are evaluating our medicines, including our triple combination regimen, in additional patient populations, including younger children, with the goal of having small molecule treatments for up to 90% of people with CF. We are also pursuing genetic therapies to address the remaining 10% of people with CF.

Beyond CF, our small molecule programs include programs focused on developing treatments for alpha-1 antitrypsin, or AAT, deficiency, APOL1-mediated kidney diseases and pain. We are also focused on developing cell and genetic therapies for various diseases in our pipeline. We are evaluating CTX001, a genetic therapy, as a potential treatment for sickle cell disease, or SCD, and transfusion-dependent beta thalassemia, or TDT, in Phase 1/2 clinical trials in collaboration with CRISPR Therapeutics AG, or CRISPR. In T1D, we are pursuing two programs for the transplant of functional islets into patients: transplantation of islet cells alone, using immunosuppression to protect the implanted cells, and implantation of the islet cells inside a novel immunoprotective device. In 2020, we continued to advance our cell and genetic therapy pipeline programs through internal research efforts and investing in business development transactions to access emerging technologies.

## Financial Highlights

## Revenues

In 2020, our net product revenues continued to increase due to the approval of TRIKAFTA in late 2019 and uptake of our medicines in ex-U.S. markets following the approval of KAFTRIO and completion of several significant reimbursement agreements.



## Expenses

Our total R&D and SG&A expenses increased from $2.41 billion in 2019 to $2.60 billion in 2020. In 2020, cost of sales was approximately 12% of our net product revenues.






## Business Updates

## Cystic Fibrosis

We expect to continue to grow our CF business through increasing the number of people with CF eligible and able to receive our medicines and providing improved treatment options for people who are already eligible for one of our medicines. Since the beginning of 2020, we have made important progress in activities supporting these efforts.

• In August, the European Commission granted marketing authorization for KAFTRIO to treat people with CF 12 years of age and older with one F508del mutation and one minimal function mutation, or two F508del mutations.

- The FDA expanded the eligibility for TRIKAFTA to include people with CF 12 years of age and older with certain mutations that are responsive to TRIKAFTA based on in vitro data. SYMDEKO and KALYDECO also received approvals to include additional responsive mutations in people with CF 6 years of age and older and 4 months of age and older, respectively.

- In January 2021, the FDA accepted our supplemental New Drug Application, or SNDA, for TRIKAFTA for the treatment of children with CF 6 to 11 years of age with at least one F508del mutation or have certain mutations that are responsive to TRIKAFTA based on in vitro data. The FDA granted Priority Review of the SNDA.

- The European Commission approved the label extension of SYMKEV1 in combination with KALYDECO for the treatment of children with CF 6 years of age and older with two F508del mutations or one F508del mutation and certain residual function mutations.

- The FDA approved KALYDECO for treatment of infants with CF four months of age and older who have at least one mutation in their CFTR gene that is responsive to KALYDECO.

- The European Commission approved KALYDECO for treatment of infants with CF four months of age and older who have the R117H mutation or certain gating mutations.

## Pipeline

We continue to advance a broad pipeline of potentially transformative small molecule, cell and genetic therapies aimed at treating serious diseases. Since the beginning of 2020, we have made important progress in activities supporting these efforts.

## Beta Thalassemia and Sickle Cell Disease

- In December, we and our collaborator, CRISPR, announced positive interim data from 10 people with TDT or SCD treated with CTX001 and that 20 people with severe hemoglobinopathies have been dosed with CTX001 in the ongoing Phase 1/2 clinical trials. Enrollment and dosing are ongoing, and completion of enrollment in both clinical trials is expected in 2021.

## Alpha-1 Antitrypsin Deficiency.

- Enrollment is ongoing in a Phase 2 proof-of-concept clinical trial for the corrector VX-864. We expect data from this clinical trial in the first half of 2021.

- We discontinued development of VX-814, our first corrector, based on the safety and pharmacokinetic profile of VX-814 observed in a Phase 2 clinical trial.

## APOL1-Mediated Kidney Diseases

- Enrollment is ongoing in a Phase 2 proof-of-concept clinical trial designed to evaluate the reduction of proteinuria in people with APOL1-mediated FSGS after treatment with VX-147. We expect data from this clinical trial in 2021.

## Type 1 Diabetes

- We are developing a cell therapy designed to replace insulin-producing islet cells in patients with T1D. We are pursuing two programs for the transplant of these functional islets into patients: transplantation of islet cells alone,



using immunosuppression to protect the implanted cells, and implantation of the islet cells inside a novel immunoprotective device.

- In January 2021, the FDA cleared our IND for VX-880, the islet cells alone program. We expect to initiate a Phase 1/2 clinical trial evaluating this program in the first half of 2021. This clinical trial will involve an infusion of fully differentiated, functional islet cells, and chronic administration of concomitant immunosuppressive therapy, to protect the islet cells from immune rejection.

## Investment in External Innovation

- We entered into a collaboration with Skyhawk Therapeutics, Inc., or Skyhawk, for the discovery and development of novel small molecules that modulate RNA splicing for the treatment of serious diseases.

- We entered into a new collaboration with Moderna, Inc., or Moderna, aimed at the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies to lung cells for the treatment of CF.

- We entered into a collaboration with Affinia Therapeutics, Inc., or Affinia, to gain access to a novel library of AAV capsids to support on our ongoing research and development efforts in genetic therapies, including DMD, DM1 and CF.

## COVID-19

We continue to monitor the impacts of the COVID-19 global pandemic on our business. COVID-19 has not affected our supply chain or the demand for our medicines, and we believe that we will be able to continue to supply all of our approved medicines to patients globally. We have adjusted our business operations in response to COVID-19, with a majority of our employees continuing to work remotely. We continue to monitor local COVID-19 trends and government guidance for each of our site locations, and are utilizing a phased, site-specific approach to assess employee access to our sites. Currently, all of our research and manufacturing sites are open to essential employees. To provide a safe working environment for our on-site employees, we have, among other things, limited employee numbers at our open sites and increased safety measures, including at home and on-site testing in the U.S., enhanced cleaning and sanitation protocols, required use of personal protective equipment for all on-site employees, hand sanitation stations throughout our open sites and implementation of various social distancing measures while on-site.

## Research

We continue to invest in our research programs and foster scientific innovation in order to identify and develop transformative medicines. Our strategy is to combine transformative advances in the understanding of human disease and the science of therapeutics in order to identify and develop new medicines. We believe that pursuing innovative approaches to treat diverse diseases of great unmet need allows us to balance the risks inherent in drug development and may provide drug candidates that will form our pipeline in future years. To supplement our internal research programs, we acquire technologies and programs and collaborate with biopharmaceutical and technology companies, leading academic research institutions, government laboratories, foundations and other organizations, as needed, to advance research in our areas of therapeutic interest and to access technologies needed to execute on our strategy.

## Drug Discovery and Development

Discovery and development of a new pharmaceutical product is a difficult and lengthy process that requires significant financial resources along with extensive technical and regulatory expertise. Potential drug candidates are subjected to rigorous evaluations, driven in part by stringent regulatory considerations, designed to generate information concerning efficacy, side effects, proper dosage levels and a variety of other physical and chemical characteristics that are important in determining whether a drug candidate should be approved for marketing as a pharmaceutical product. Most chemical compounds that are investigated as potential drug candidates never progress into development, and most drug candidates that do advance into development never receive marketing approval. Because our investments in drug candidates are subject to considerable risks, we closely monitor the results of our discovery, research, clinical trials and nonclinical studies and frequently evaluate our drug development programs in light of new data and scientific, business and commercial insights, with the objective of balancing risk and potential. This process can result in rapid changes in focus and priorities as new information becomes available and as we gain additional understanding of our ongoing programs and potential new programs, as well as those of our competitors. For example, in October 2020, we discontinued development of VX-814, a



drug candidate for the treatment of AAT, based on the safety and pharmacokinetic profile of VX-814 observed in a Phase 2 clinical trial.

If we believe that data from a completed registration program support approval of a drug candidate, we submit an NDA or BLA to the FDA requesting approval to market the drug candidate in the U.S. and seek analogous approvals from comparable regulatory authorities in jurisdictions outside the U.S. To obtain approval, we must, among other things, demonstrate with evidence gathered in nonclinical studies and well-controlled clinical trials that the drug candidate is safe and effective for the disease it is intended to treat and that the manufacturing facilities, processes and controls for the manufacture of the drug candidate are adequate. The FDA and ex-U.S. regulatory authorities have substantial discretion in deciding whether or not a drug candidate should be granted approval based on the benefits and risks of the drug candidate in the treatment of a particular disease, and could delay, limit or deny regulatory approval. If regulatory delays are significant or regulatory approval is limited or denied altogether, our financial results and the commercial prospects for the drug candidate involved will be harmed.

## Regulatory Compliance

Our marketing of pharmaceutical products is subject to extensive and complex laws and regulations. We have a corporate compliance program designed to actively identify, prevent and mitigate risk through the implementation of compliance policies and systems and through the promotion of a culture of compliance. Among other laws, regulations and standards, we are subject to various U.S. federal and state laws, and comparable laws in other jurisdictions, pertaining to health care fraud and abuse, including anti-kickback and false claims laws, and laws prohibiting the promotion of drugs for unapproved or off-label uses. Anti-kickback laws generally make it illegal for a prescription drug manufacturer to knowingly and willfully solicit, offer, receive or pay any remuneration in return for or to induce the referral of business, including the purchase or prescription of a particular drug that is reimbursed by a state or federal health care program. False claims laws prohibit anyone from knowingly or willfully presenting for payment to third-party payors, including Medicare and Medicaid, claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services. We are subject to laws and regulations that regulate the sales and marketing practices of pharmaceutical manufacturers, as well as laws such as the U.S. Foreign Corrupt Practices Act, which govern our international business practices with respect to payments to government officials. In addition, we are subject to various data protection and privacy laws and regulations in the U.S., E.U., U.K., Canada, Australia and other jurisdictions. We expect to continue to devote substantial resources to maintain, administer and expand these compliance programs globally.

## Reimbursement

Sales of our products depend, to a large degree, on the extent to which our products are reimbursed by third-party payors, such as government health programs, commercial insurance and managed health care organizations. We dedicate substantial management and other resources in order to obtain and maintain appropriate levels of reimbursement for our products from third-party payors, including governmental organizations in the U.S. and ex-U.S. markets.

In the U.S., we have worked successfully with third party payors in order to promptly obtain appropriate levels of reimbursement for our CF medicines. We plan to continue to engage in discussions with numerous commercial insurers and managed health care organizations, along with government health programs that are typically managed by authorities in the individual states, to ensure that payors recognize the significant benefits that our medicines provide by treating the underlying cause of CF and continue to provide access to our medicines.

In Europe and other ex-U.S. markets, we seek government reimbursement for our medicines on a country-by-country basis. This is necessary for each new medicine, as well as label expansions for our current medicines. We successfully obtained reimbursement for KALYDECO in each significant ex-U.S. market within two years of approval, but experienced significant challenges in obtaining reimbursement for ORKAMBI in certain ex-U.S. markets. With the completion of reimbursement discussions in England and France in 2019, we have reimbursement for ORKAMBI or SYMKEVI in most of our significant ex-U.S. markets. In addition, in several ex-U.S. markets, including England, Ireland, Denmark and Australia, our reimbursement agreements include innovative arrangements that provide a pathway to access and rapid reimbursement for certain future CF medicines. For example, our existing reimbursement agreements in England, Ireland, and Denmark have been expanded to include KAFTRIO. We expect to continue to focus significant resources to obtain appropriate reimbursement for our products in ex-U.S. markets.



## Strategic Transactions

## Acquisitions

As part of our business strategy, we seek to acquire drugs, drug candidates and other technologies and businesses that have the potential to complement our ongoing research and development efforts. In 2019, we invested significantly in business development transactions designed to augment our pipeline, including the acquisition of Semma Therapeutics, Inc., or Semma, a privately-held company focused on the use of stem cell-derived human islets as a potentially curative treatment for T1D, and Exonics Therapeutics, Inc., or Exonics, a privately-held company focused on creating transformative gene-editing therapies to repair mutations that cause DMD and other severe neuromuscular diseases, including DM1. In the Semma acquisition, we paid approximately $950.0 million in cash to Semma equity holders. In the Exonics acquisition, we paid approximately $245.0 million upfront to Exonics equity holders and agreed to additional payments based upon successful achievement of specified development and regulatory milestones. We expect to continue to identify and evaluate potential acquisitions and may include larger transactions or later stage assets.

Both of our 2019 acquisitions were accounted for as business combinations. As of the acquisition date for each transaction, the cash payments, as well as the fair value of contingent consideration for Exonics, were allocated primarily to goodwill and the fair value of several in-process research and development assets that we acquired. The fair value of contingent consideration related to Exonics was recorded as a liability and continues to be adjusted on a quarterly basis. As a result, these acquisitions are primarily reflected in additional assets and liabilities on our consolidated balance sheet. Operating expenses incurred by Exonics and Semma after the acquisition dates and specific expenses associated with the acquisitions are reflected in our consolidated statement of operations.

Please refer to our critical accounting policies, “Acquisitions,” for further information regarding the significant judgments and estimates related to our acquisitions.

## Collaboration and Licensing Arrangements

We enter into arrangements with third parties, including collaboration and licensing arrangements, for the development, manufacture and commercialization of drugs, drug candidates and other technologies that have the potential to complement our ongoing research and development efforts. We expect to continue to identify and evaluate collaboration and licensing opportunities that may be similar to or different from the collaborations and licenses that we have engaged in previously.

## In-License Agreements

We have entered into collaborations with biotechnology and pharmaceutical companies in order to acquire rights or to license drug candidates or technologies that enhance our pipeline and/or our research capabilities. Over the last several years, we entered into collaboration agreements with a number of companies, including Affinia, Arbor Biotechnology, Inc., CRISPR, Kymera Therapeutics, Inc., Moderna, Molecular Templates, Inc. and Skyhawk. Generally, when we in-license a technology or drug candidate, we make upfront payments to the collaborator, assume the costs of the program and/or agree to make contingent payments, which could consist of milestone, royalty and option payments. Most of these collaboration payments are expensed as research and development expenses; however, depending on many factors, including the structure of the collaboration, the significance of the in-licensed drug candidate to the collaborator's operations and the other activities in which our collaborators are engaged, the accounting for these transactions can vary significantly. Our research and development expenses included $184.6 million in 2020, $318.3 million in 2019 and $111.9 million in 2018 related to upfront and milestone payments pursuant to our collaboration agreements.

## Out-License Agreements

We also have out-licensed internally-developed programs to collaborators who are leading the development of these programs. These out-license arrangements include our agreement with Merck KGaA, Darmstadt, Germany, which licensed oncology research and development programs from us in early 2017. Pursuant to these out-licensing arrangements, our collaborators are responsible for the research, development and commercialization costs associated with these programs, and we are entitled to receive contingent milestone and/or royalty payments. As a result, we do not expect to incur significant expenses in connection with these programs and have the potential for future collaborative and royalty revenues resulting from these programs.



Please refer to Note B, “Collaborative Arrangements,” for further information regarding our in-license agreements and out-license agreements.

## Strategic Investments

In connection with our business development activities, we have periodically made equity investments in our collaborators. As of December 31, 2020, we held strategic equity investments in several public companies and certain private companies, and we plan to make additional strategic equity investments in the future. While we invest the majority of our cash, cash equivalents and marketable securities in instruments that meet specific credit quality standards and limit our exposure to any one issue or type of instrument, our strategic investments are maintained and managed separately from our other cash, cash equivalents and marketable securities. Any changes in the fair value of equity investments with readily determinable fair values (including publicly traded securities) are recorded to other income (expense), net in our consolidated statement of operations.

In 2020, 2019 and 2018, we recorded within other income (expense), net gains of $311.9 million, $197.6 million and $2.6 million, respectively, related to changes in the fair value of our strategic investments and from sales of certain investments. As of December 31, 2020, the fair value of our investments in publicly traded companies was $195.8 million. To the extent that we continue to hold strategic investments, particularly strategic investments in publicly traded companies, we will record other income (expense) related to these strategic investments on a quarterly basis. Due to the increased volatility of the global markets, including as a result of COVID-19, and the high volatility of stocks in the biotechnology industry, we expect the value of these strategic investments to fluctuate and that the increases or decreases in the fair value of these strategic investments will continue to have material impacts on our net income (expense) and our profitability on a quarterly and/or annual basis.

## Net Income Attributable to Vertex

Our net income attributable to Vertex increased to $2.71 billion in 2020 as compared to $1.18 billion in 2019 primarily due to increased revenues and increased other income (expense) related to our strategic investments partially offset by increased operating costs and expenses and an increased provision for income taxes. The increased revenues were primarily due to the U.S. approval of TRIKAFTA in the fourth quarter of 2019, E.U. approval of KAFTRIO in the third quarter of 2020 and continued uptake of our medicines in ex-U.S. markets. The increased operating costs and expenses were primarily due to increased cost of sales consistent with increased net product revenues, increased investment in research and development and increased sales, general and administrative expenses to support our business.

Net income attributable to Vertex in 2018 included a one-time non-cash benefit from income taxes of $1.56 billion resulting from our release of our valuation allowance. Net income attributable to Vertex decreased in 2019 as compared to 2018 as a result of this one-time tax benefit and increased operating costs and expenses. The increases in operating costs and expenses were primarily due to increased cost of sales due to increased net product revenues and increased research expenses associated with our business development activities. These decreases in our net income in 2019 as compared to 2018 were partially offset by increased net product revenues and increased gains recorded to other income (expense) related to our strategic investments.

## Earnings Per Share

In 2020, 2019, and 2018, net income attributable to Vertex was $10.29, $4.51 and $8.09, respectively, per diluted share. In 2018, the benefit from income taxes as a result of the release of our valuation allowance increased net income attributable to Vertex by $6.03 per diluted share.

In 2020, our net product revenues increased by $2.04 billion as compared to 2019. In 2019, our net product revenues increased by $1.12 billion as compared to 2018. The increase in total net product revenues in 2020 was primarily due to the launch of TRIKAFTA in the U.S in the fourth quarter of 2019 and KAFTRIO in the E.U. in the third quarter of 2020. Decreases in revenues for our other products were the result of patients in the U.S. switching from these medicines to TRIKAFTA, partially offset by label expansions and expanded access to our medicines in ex-U.S. markets. The increase in total net product revenues in 2019 was primarily due to the increasing number of patients being treated with SYMDEKO/SYMKEVI, the October 2019 approval of TRIKAFTA in the U.S., label expansions for KALYDECO and ORKAMBI and expanded access to our medicines in ex-U.S. markets. In 2020, 2019 and 2018, our net product revenues included product revenues of $1.4 billion, $1.1 billion and $682.4 million, respectively, from ex-U.S. markets.

We expect that our net product revenues will increase in 2021 due to increasing numbers of people being treated with our medicines as a result of the continued uptake of TRIKAFTA, the approval of KAFTRIO by the European Commission, label expansions for our previously approved products and expanded access to our medicines.

Upon reaching an agreement with the French government for ORKAMBI in the fourth quarter of 2019, including the final amount for ORKAMBI distributed through early access programs, we recognized an adjustment to increase net product revenues related to prior period shipments of ORKAMBI distributed through early access programs of $155.8 million. Please refer to “Critical Accounting Policies - Revenue Recognition” below for a discussion of our accounting treatment for our early access program for ORKAMBI in France.

## Collaborative and Royalty Revenues

Our collaborative and royalty revenues were $2.9 million, $2.1 million and $9.3 million in 2020, 2019 and 2018, respectively. Our collaborative revenues have historically fluctuated significantly from one period to another and may continue to fluctuate in the future. Our future royalty revenues will be dependent on if, and when, our collaborators are able to successfully develop drug candidates that we have out-licensed to them.

** Not meaningful

## Cost of Sales

Our cost of sales primarily consists of the third-party royalties payable on our net sales of our products as well as the cost of producing inventories that corresponded to product revenues for the reporting period. Pursuant to our agreement with the Cystic Fibrosis Foundation, or CFF, our tiered third-party royalties on sales of TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, KALYDECO and ORKAMBI, calculated as a percentage of net sales, range from the single digits to the sub-teens, with royalties on sales of TRIKAFTA/KAFTRIO slightly lower than for our other products. Over the last several years, our cost of sales has been increasing due to increased net product revenues. Our cost of sales as a percentage of our net product revenues was approximately 12%, 13%, and 13% for 2020, 2019 and 2018, respectively. In 2021, we expect our total cost of sales will increase due to expected increases in our net product revenues and our cost of sales as a percentage of total net product revenues will be similar to our cost of sales as a percentage of total net product revenues in 2020.

Our research and development expenses include internal and external costs incurred for research and development of our drugs and drug candidates and expenses related to certain technology that we acquire or license through business development transactions. We do not assign our internal costs, such as salary and benefits, stock-based compensation expense, laboratory supplies and other direct expenses and infrastructure costs, to individual drugs or drug candidates, because the employees within our research and development groups typically are deployed across multiple research and development programs. These internal costs are significantly greater than our external costs, such as the costs of services provided to us by clinical research organizations and other outsourced research, which we allocate by individual program. All research and development costs for our drugs and drug candidates are expensed as incurred.

Over the past three years, we have incurred $5.0 billion in research and development expenses associated with drug discovery and development. The successful development of our drug candidates is highly uncertain and subject to a number of risks. In addition, the duration of clinical trials may vary substantially according to the type, complexity and novelty of the drug candidate and the disease indication being targeted. The FDA and comparable agencies in foreign countries impose substantial requirements on the introduction of therapeutic pharmaceutical products, typically requiring lengthy and detailed laboratory and clinical testing procedures, sampling activities and other costly and time-consuming procedures. Data obtained from nonclinical and clinical activities at any step in the testing process may be adverse and lead to discontinuation or redirection of development activities. Data obtained from these activities also are susceptible to varying interpretations,



which could delay, limit or prevent regulatory approval. The duration and cost of discovery, nonclinical studies and clinical trials may vary significantly over the life of a project and are difficult to predict. Therefore, accurate and meaningful estimates of the ultimate costs to bring our drug candidates to market are not available.

In 2020, 2019 and 2018, costs related to our CF programs represented the largest portion of our development costs. Any estimates regarding development and regulatory timelines for our drug candidates are highly subjective and subject to change. Until we have data from Phase 3 clinical trials, we cannot make a meaningful estimate regarding when, or if, a clinical development program will generate revenues and cash flows.

We expect to continue to invest in our research programs with a focus on identifying drug candidates with the goal of creating transformative medicines for serious diseases. Our total research expenses have historically fluctuated, and are expected to continue to fluctuate, from one period to another due to upfront and milestone payments related to our business development activities that are reflected in the preceding table as collaborative payments. Our research expenses, excluding these collaborative payments, have been increasing over the last several years as we have invested in our pipeline and expanded our cell and genetic therapies capabilities.

Our development expenses increased by $171.0 million, or 17%, in 2020 as compared to 2019 and increased by $43.7 million, or 4%, in 2019 as compared to 2018, primarily due to increased expenses related to our diversifying pipeline, including clinical trials, headcount and infrastructure costs. We expect our development expenses to continue to increase in 2021 as a result of our advancing pipeline.

<table><tr><td rowspan="3"></td><td colspan="6">2020/2019</td><td colspan="2">2019/2018</td></tr><tr><td colspan="6">Comparison</td><td colspan="2">Comparison</td></tr><tr><td>2020</td><td>2019</td><td>2018</td><td colspan="2">Increase/(Decrease)</td><td colspan="2">Increase/(Decrease)</td><td></td></tr><tr><td>Sales, general and administrative expenses</td><td>$</td><td>770,456</td><td>$</td><td>658,498</td><td>$</td><td>17%</td><td>$</td><td>18%</td></tr></table>

Sales, general and administrative expenses increased by 17% in 2020 as compared to 2019, and by 18% in 2019 as compared to 2018, primarily due to increased global support for our medicines, including incremental investment to support the launch of our triple combination regimen and increased support for our CF pipeline products and other disease areas. We expect our sales, general and administrative expenses to continue to increase in 2021.

## Contingent Consideration

In 2020 and 2019, the increase in the fair value of contingent consideration potentially payable to Exonics' former equity holders was $13.1 million and $4.5 million, respectively, primarily due to changes in market interest rates. There were no similar amounts in 2018. In future periods, we expect the fair value of contingent consideration to increase or decrease based on, among other things, our estimates of the probability of achieving and the timing of these contingent development and regulatory milestone payments, as well as the time value of money changes in market interest rates.

## Intangible Asset Impairment Charge

In 2018, we recorded a $29.0 million impairment charge related to VX-210 that was licensed from BioAxone Biosciences, Inc., or BioAxone, in 2014. This charge was attributable to non-controlling interest on our consolidated statement of operations because we consolidated BioAxone as a variable interest entity, or VIE, until December 31, 2018. There were no corresponding intangible asset impairment charges in 2020 or 2019.

## Other Non-Operating Income (Expense), Net

## Interest Income

Interest income increased from $38.4 million in 2018 to $63.7 million in 2019 and decreased to $22.2 million in 2020. The increase in our interest income in 2019 as compared to 2018 was primarily due to increases in our cash equivalents and available-for-sale debt securities and prevailing market interest rates. The decrease in our interest income in 2020 as compared to 2019 was primarily due to a decrease in prevailing market interest rates despite continued increases in our cash equivalents and available-for-sale debt securities. Our future interest income will be dependent on the amount of, and prevailing market interest rates on, our outstanding cash equivalents and available-for-sale debt securities.

## Interest Expense

Interest expense was $58.2 million in 2020, $58.5 million in 2019 and $72.5 million in 2018. The majority of our interest expense in these periods was related to imputed interest expense associated with our leased corporate headquarters in Boston and our research site in San Diego. On January 1, 2019, we adopted ASC 842, Leases, which resulted in a reduction in our imputed interest expense associated with these leases in 2020 and 2019. Our future interest expense will be dependent on whether, and to what extent, we borrow amounts under our credit facilities.

## Other Income (Expense), Net

In 2020 and 2019, we recorded net other income of $296.4 million and $192.2 million, respectively, primarily related to changes in the fair value of our strategic investments. In 2018, we recorded net other expense of $0.8 million. We expect that due to the volatility of the stock price of biotechnology companies, our other income (expense), net will fluctuate in future periods based on increases or decreases in the fair value of our strategic investments.



## Noncontrolling Interest (VIEs)

In 2018, our $9.8 million net loss attributable to noncontrolling interest reflects BioAxone’s net loss for the reporting period. We deconsolidated BioAxone from our consolidated financial statements as of December 31, 2018 and did not consolidate any VIEs into our consolidated financial statements in 2020 or 2019.

## Income Taxes

Our provision for income taxes was $405.2 million for 2020 and $218.1 million for 2019. Our effective tax rate of 13% for 2020 was lower than the U.S. statutory rate primarily due to (i) discrete tax benefits associated with the $209.0 million transfer of intellectual property rights to the U.K., the write-off of a long-term intercompany receivable, and an increase in the U.K.'s corporate tax rate; and (ii) excess tax benefits related to stock-based compensation. The impact of these items was partially offset by a U.S. deemed dividend. Our effective tax rate of 16% for 2019 was lower than the U.S. statutory rate primarily due to excess tax benefits related to stock-based compensation and research and development tax credits.

In 2018, we recorded a benefit from income taxes of $1.5 billion because we released our valuation allowance on the majority of our net operating losses and other deferred tax assets in the fourth quarter of 2018, resulting in a non-cash credit to net income of $1.56 billion. Starting in 2019, we began recording a provision for income taxes on our pre-tax income using an effective tax rate approximating statutory rates. Due to our ability to offset our pre-tax income against previously benefited net operating losses, the majority of our tax provision in 2020 and 2019 represented a non-cash expense. We utilized substantially all of our remaining previously benefited U.S. net operating losses in 2020. As a result, a larger portion of our tax provision will represent a cash tax payable in future periods.

## LIQUIDITY AND CAPITAL RESOURCES

The following table summarizes the components of our financial condition as of December 31, 2020 and 2019:

<table><tr><td rowspan="2"></td><td rowspan="2">2020</td><td rowspan="2">2019</td><td colspan="2">Increase/(Decrease)</td></tr><tr><td>$</td><td>%</td></tr><tr><td>Cash, cash equivalents and marketable securities</td><td></td><td></td><td></td><td></td></tr><tr><td>Working Capital:</td><td>$</td><td>6,658,897</td><td>$</td><td>2,850,603</td></tr><tr><td>Total current assets</td><td></td><td></td><td></td><td></td></tr><tr><td>Total current liabilities</td><td>$</td><td>8,133,379</td><td>$</td><td>3,310,550</td></tr><tr><td>Total working capital</td><td></td><td>(1,877,533)</td><td></td><td>(542,706)</td></tr><tr><td></td><td>$</td><td>6,255,846</td><td>$</td><td>2,767,844</td></tr><tr><td></td><td></td><td></td><td></td><td></td></tr></table>

As of December 31, 2020, total working capital was $6.3 billion, which represented an increase of $2.8 billion from $3.5 billion as of December 31, 2019. The increase in total working capital in 2020 was primarily related to $3.3 billion of cash provided by operations partially offset by $539.1 million of cash used to repurchase our common stock pursuant to our share repurchase programs and purchases of property and equipment of $259.8 million.

## Sources of Liquidity

As of December 31, 2020, we had cash, cash equivalents and marketable securities of $6.7 billion, which represented an increase of $2.9 billion from $3.8 billion as of December 31, 2019. We intend to rely on our existing cash, cash equivalents and marketable securities together with cash flows from product sales as our primary source of liquidity.

We may borrow up to a total of $2.5 billion pursuant to two revolving credit facilities. We may repay and reborrow amounts under these revolving credit agreements without penalty. Subject to certain conditions, we may request that the borrowing capacity for each of the credit agreements be increased by an additional $500.0 million, for a total of $3.5 billion collectively. Other possible sources of future liquidity include commercial debt, public and private offerings of our equity and debt securities, strategic sales of assets or businesses and financial transactions. Negative covenants in our credit agreement may prohibit or limit our ability to access these sources of liquidity. As of December 31, 2020, we were in compliance with these covenants.



## Future Capital Requirements

We have significant future capital requirements including:

• significant expected operating expenses to conduct research and development activities and to operate our organization; and

• substantial facility and finance lease obligations.

In addition:

- We have entered into certain collaboration agreements with third parties that include the funding of certain research, development and commercialization efforts. Certain of our business development transactions, including collaborations and acquisitions, include the potential for future milestone and royalty payments by us upon the achievement of pre-established developmental and regulatory targets and/or commercial targets. We may enter into additional business development transactions, including acquisitions, collaborations and equity investments, that require additional capital.

- To the extent we borrow amounts under the credit agreements we entered into in 2020 and 2019, we would be required to repay any outstanding principal amounts in 2022 or 2024, respectively.

- As of December 31, 2020, $424.9 million remained available to fund repurchases under the 2020 Share Repurchase Program that we announced in November 2020.

We expect that cash flows from our products together with our current cash, cash equivalents and marketable securities will be sufficient to fund our operations for at least the next twelve months and do not expect COVID-19 to have an adverse effect on our liquidity. The adequacy of our available funds to meet our future operating and capital requirements will depend on many factors, including the amounts of future revenues generated by our products, and the potential introduction of one or more of our other drug candidates to the market, the level of our business development activities and the number, breadth, cost and prospects of our research and development programs.

## Financing Strategy

We may raise additional capital by borrowing under credit agreements, through public offerings or private placements of our securities or securing new collaborative agreements or other methods of financing. We will continue to manage our capital structure and will consider all financing opportunities, whenever they may occur, that could strengthen our long-term liquidity profile. There can be no assurance that any such financing opportunities will be available on acceptable terms, if at all.

## CONTRACTUAL COMMITMENTS AND OBLIGATIONS

The following table sets forth our commitments and obligations as of December 31, 2020:

<table><tr><td rowspan="3"></td><td colspan="6">Payments Due by Period</td></tr><tr><td>2021</td><td>2022-2023</td><td>2024-2025</td><td>2026 and later</td><td>Total</td><td></td></tr><tr><td colspan="6">(in thousands)</td></tr><tr><td>Fan Pier Leases</td><td>$ 66,540</td><td>$ 145,177</td><td>$ 155,942</td><td>$ 233,913</td><td>$ 601,572</td><td></td></tr><tr><td>Finance leases, excluding Fan Pier Leases</td><td>18,930</td><td>33,028</td><td>30,913</td><td>182,542</td><td>265,413</td><td></td></tr><tr><td>Operating leases</td><td>15,266</td><td>68,782</td><td>65,677</td><td>320,684</td><td>470,409</td><td></td></tr><tr><td>Research and development costs</td><td>66,955</td><td>1,724</td><td>—</td><td>—</td><td>68,679</td><td></td></tr><tr><td>Total contractual commitments and obligations</td><td>$ 167,691</td><td>$ 248,711</td><td>$ 252,532</td><td>$ 737,139</td><td>$ 1,406,073</td><td></td></tr></table>

## Leases

We lease two buildings that are located at Fan Pier in Boston, Massachusetts. We commenced lease payments on these two buildings in December 2013 and the initial lease periods end in December 2028. We also lease office and laboratory



space in San Diego, California. We commenced lease payments for this building in the second quarter of 2019 pursuant to an initial 16 year lease term. The future minimum rental payments that we are obligated to pay related to the San Diego building are included in “Finance leases, excluding Fan Pier Leases,” which also reflects leases of equipment and a land lease. The remainder of our real estate leases are reflected in “Operating leases” in the table above, including office and laboratory space at our Cell and Genetic Therapies facility near our corporate headquarters. Base rent payments will commence for this building in the fourth quarter of 2021 pursuant to an initial 15 year lease term.

## Research and Development Costs

“Research and development costs” included in the table above primarily relate to pharmaceutical materials to be utilized in our clinical trials and research costs related to our advancing pipeline. The amounts reflected in “Research and development costs” do not include certain payments we anticipate making to clinical research organizations, or CROs, because these contracts are cancelable, at our option, with notice. However, we historically have not cancelled such contracts. As of December 31, 2020, we had accrued $42.8 million related to these contracts for costs incurred for services provided through December 31, 2020, and we have approximately $237.6 million in cancelable future commitments based on existing contracts as of December 31, 2020. These amounts reflect planned expenditures based on existing contracts and do not reflect any future modifications to, or terminations of, existing contracts or anticipated or potential new contracts.

## Collaborative Arrangements and Asset Acquisitions

We have entered into certain research and development collaboration agreements with third parties and acquired certain assets that include the funding of certain development, manufacturing and commercialization efforts with the potential for future milestone and royalty payments by us upon the achievement of pre-established developmental, regulatory and/or commercial targets. Our obligation to fund these efforts is contingent upon continued involvement in the programs and/or the lack of any adverse events that could cause the discontinuance of the programs. These payments, which are not included in the contractual obligations table above, include:

• CFF: We pay royalties, which are included in cost of sales, to CFF on sales of our CF products.

- Research and Development Milestones: The majority of our in-license agreements and our acquisitions have milestone and royalty payments payable by us upon the successful achievement of pre-established developmental, regulatory and/or commercial targets or net sales. Contingent payments under these agreements become due and payable only upon achievement of certain milestones.

## Tax-related Obligations

We exclude liabilities pertaining to uncertain tax positions from our summary of contractual obligations as we cannot make a reliable estimate of the period of cash settlement with the respective taxing authorities. As of December 31, 2020, our liabilities associated with uncertain tax positions were $86.6 million.

## Other Funding Commitments

Our table detailing contractual commitments and obligations does not include severance payment obligations to certain of our executive officers in the event of a not-for-cause employment termination under existing employment contracts. We will provide information regarding these obligations annually in our proxy statement for our annual meeting of shareholders.



## CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements prepared in accordance with generally accepted accounting principles in the U.S. The preparation of these financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. These items are monitored and analyzed by management for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are reflected in reported results for the period in which the change occurs. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates if past experience or other assumptions do not turn out to be substantially accurate.

We believe that our application of the following accounting policies, each of which requires significant judgments and estimates on the part of management, are the most critical to aid in fully understanding and evaluating our reported financial results:

• revenue recognition;

• acquisitions, including intangible assets, goodwill and contingent consideration; and

• income taxes.

Our accounting policies, including the ones discussed below, are more fully described in the Notes to our consolidated financial statements, including Note A, “Nature of Business and Accounting Policies,” included in this Annual Report on Form 10-K.

## Revenue Recognition

## Product Revenues, Net

We generate product revenues from sales in the U.S. and in international markets. We sell our products principally to a limited number of specialty pharmacy and specialty distributors in the U.S., which account for the largest portion of our total revenues, and make international sales primarily to specialty distributors and retail chains, as well as hospitals and clinics, many of which are government-owned or supported customers, collectively, our customers. Our customers in the U.S. subsequently resell our products to patients and health care providers. We contract with government agencies so that our products will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. We recognize net product revenues from sales of our products when our customers obtain control of our products, which typically occurs upon delivery to our customers. Revenues from our product sales are recorded at the net sales price, or “transaction price,” which requires us to make several significant estimates regarding the net sales price.

The most significant estimate we are required to make is related to government and private payor rebates, chargebacks, discounts and fees, collectively rebates. The value of the rebates provided to third-party payors per course of treatment vary significantly and are based on government-mandated discounts and our arrangements with other third-party payors. In order to estimate our total rebates, we estimate the percentage of prescriptions that will be covered by each third-party payor, which is referred to as the payor mix. We track available information regarding changes, if any, to the payor mix for our products, to our contractual terms with third-party payors and to applicable governmental programs and regulations and levels of our products in the distribution channel. We adjust our estimated rebates based on new information, including information regarding actual rebates for our products, as it becomes available. Claims by third-party payors for rebates are submitted to us significantly after the related sales, potentially resulting in adjustments in the period in which the new information becomes known. Our credits to revenue related to prior period sales, excluding the adjustment to the transaction price for ORKAMBI distributed through early access programs in France in 2019, have not been significant (typically less than 1% of gross product revenues) and primarily related to U.S. rebates.



The following table summarizes activity related to our accruals for rebates (including our refund liability to the French government related to ORKAMBI distributed through early access programs in France as described below) for the three years ended December 31, 2020:

<table><tr><td colspan="2">(in thousands)</td></tr><tr><td>Balance as of December 31, 2017</td><td>$ 112,215</td></tr><tr><td>Provision related to 2018 sales and the adoption of ASC 606</td><td>684,299</td></tr><tr><td>Adjustments related to prior year(s) sales</td><td>(22,099)</td></tr><tr><td>Credits/payments made</td><td>(229,361)</td></tr><tr><td>Balance as of December 31, 2018</td><td>$ 545,054</td></tr><tr><td>Provision related to 2019 sales</td><td>655,980</td></tr><tr><td>Adjustments related to prior year(s) sales</td><td>(95,480)</td></tr><tr><td>Credits/payments made</td><td>(469,832)</td></tr><tr><td>Balance as of December 31, 2019</td><td>$ 635,722</td></tr><tr><td>Provision related to 2020 sales</td><td>1,284,068</td></tr><tr><td>Adjustments related to prior year(s) sales</td><td>631</td></tr><tr><td>Credits/payments made</td><td>(1,144,832)</td></tr><tr><td>Balance as of December 31, 2020</td><td>$ 775,589</td></tr></table>

We have also entered into annual contracts with government-owned and supported customers in international markets that limit the amount of annual reimbursement we can receive. Upon exceeding the annual reimbursement amount, products are provided free of charge, which is a material right. We defer a portion of the consideration received, which includes upfront payments and fees, for shipments made up to the annual reimbursement limit as “Other current liabilities.” The deferred amount is recognized as revenue when the free products are shipped. In order to estimate the portion of the consideration received to recognize as revenue and the portion of the amount to defer, we rely on our forecast of the number of units we will distribute during the applicable annual period in each international market in which our contracts with government-owned and supported customers limit the amount of annual reimbursement we can receive. Our forecasts are based on, among other things, our historical experience.

The preceding estimates and judgments materially affect our recognition of net product revenues. Changes in our estimates of net product revenues could have a material effect on net product revenues recorded in the period in which we determine that change occurs.

## French Early Access Programs

In 2015, we began distributing ORKAMBI through early access programs in France and remained engaged in reimbursement discussions with the French government for ORKAMBI, including ORKAMBI distributed through early access programs, until November 2019, when we reached an agreement with the French government. From the time we began distributing ORKAMBI through early access programs in France, we expected that the difference between the amounts collected based on the invoiced amount and the final amount for ORKAMBI distributed through these programs would be returned to the French government. Our refund liability related to the early access programs in France was classified in “Accrued expenses” on our consolidated balance sheets.

From the first quarter of 2018 through the third quarter of 2019, we recognized net product revenues for ORKAMBI sales in France under the early access programs based on a transaction price that reflected our estimate of consideration we expected to retain that would not be subject to a significant reversal in amounts recognized, which resulted in revenue representing a portion of the invoiced amount.

Upon reaching an agreement with the French government for ORKAMBI, including the final amount for ORKAMBI distributed through early access programs in France in the fourth quarter of 2019, we updated the transaction price related to ORKAMBI distributed through early access programs and recognized net product revenues of $155.8 million related to these shipments, which occurred from 2015 through the date of our agreement with the French government, because the final amount for these shipments exceeded our previous estimate.



## Acquisitions

We are required to make several significant judgments and estimates in order to calculate the purchase price for our business combinations and then allocate it to the assets that we have acquired and the liabilities that we have assumed on our consolidated balance sheet. The most significant judgments and estimates relate to the fair value of the in-process research and development assets and contingent consideration liabilities related to these business combinations. Based on these judgments and estimates, the fair value of the goodwill that we record as a result of these business combinations may be material. Once recorded, these assets are subject to quarterly impairment analysis and our contingent consideration liability is adjusted quarterly, which requires similar judgments and estimates.

## Intangible Assets

In 2019, we recorded in-process research and development assets related to our acquisitions of Exonics and Semma totaling $400.0 million on our consolidated balance sheet, which remained on our consolidated balance sheet as of December 31, 2020. Each of these assets is accounted for as an indefinite-lived intangible asset and is maintained on our consolidated balance sheet until either the project underlying it is completed or the asset becomes impaired. When we determine that an asset has become impaired or we abandon a project, we write down the carrying value of the related intangible asset to its fair value and record an impairment charge in the period in which the impairment occurs. In 2018, we recorded a full impairment charge of $29.0 million for the in-process research and development asset that had previously been recorded on our consolidated balance sheets related to our collaboration with BioAxone.

To determine the fair value of our in-process research and development assets, we utilize the multi-period excess earnings method of the income approach, which requires us to make estimates of the probability of technical and regulatory success, development cost assumptions, revenue projections and growth rates, commercial cost estimates and appropriate discount rates. These assumptions require significant management judgment and reasonable changes in the assumptions can cause material changes to the fair value of the intangible assets. Due to the early stage of Exonics and Semma’s programs, these significant assumptions could be affected by future economic and market conditions.

## Contingent Consideration

As of December 31, 2020 and 2019, we had $189.6 million and $176.5 million, respectively, of liabilities on our consolidated balance sheet attributable to the fair value of the contingent development and regulatory payments that we may owe to Exonics' former equity holders upon the achievement of certain events. Our acquisition of Semma in 2019 did not include similar contingent payments; therefore, we are not required to record contingent consideration liabilities related to our acquisition of Semma.

We record an increase or a decrease in the fair value of the contingent consideration liability on our consolidated balance sheet and in our consolidated statement of operations on a quarterly basis. We determine the fair value of our contingent consideration liability using a probability weighted discounted cash flow method of the income approach, which requires us to make estimates of the timing of regulatory and commercial milestone achievement and the corresponding estimated probability of technical and regulatory success rates. Significant judgment is used in determining the appropriateness of these assumptions during each reporting period. Reasonable changes in these assumptions can cause material changes to the fair value of our contingent consideration liability. Due to the early stage of Exonics' DMD and DM1 programs, these significant assumptions could be affected by future economic and market conditions.

## Goodwill

In 2020, we did not have any business combinations; therefore, we did not record any additional goodwill on our consolidated balance sheet. In 2019, we recorded goodwill of $554.6 million and $397.1 million related to our acquisitions of Semma and Exonics, respectively. Goodwill reflects the difference between the fair value of the consideration transferred and the fair value of the net assets acquired. Thus, the goodwill that we record is dependent on the significant judgments and estimates inherent in the fair value of our in-process research and development assets and contingent consideration liabilities.

## Income Taxes

We utilize the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and tax basis of assets and liabilities using enacted tax rates in effect for years in which the temporary differences are expected to reverse. If our estimate



of the tax effect of reversing temporary differences is (i) not reflective of actual outcomes, (ii) modified to reflect new developments or interpretations of the tax law, or (iii) revised to incorporate new accounting principles, or changes in the expected timing or manner of the reversal, our results of operations could be materially impacted.

We are engaged in research and development activities and incurred significant net operating losses for a number of years before recently becoming profitable. Accordingly, we did not report any tax benefits relating to our net operating loss carryforwards and income tax credit carryforwards that were available for utilization in future periods because we maintained a valuation allowance on the majority of our net operating losses and other deferred tax assets until December 31, 2018. We released the valuation allowance on the majority of our net operating losses and other deferred tax assets resulting in a non-cash benefit from income taxes of $1.56 billion in the fourth quarter of 2018.

We provide a valuation allowance when it is more likely than not that deferred tax assets will not be realized. On a periodic basis, we reassess our valuation allowances on our deferred tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. In the fourth quarter of 2018, we reassessed our valuation allowances and considered positive evidence including significant cumulative consolidated and U.S. income over the three years ended December 31, 2018, revenue growth, clinical program progression, including the advancement and clinical trial data from our triple combination regimens, and expectations regarding future profitability, and negative evidence, including potential impact of competition on our projections and cumulative losses in the jurisdictions. After assessing both the positive evidence and the negative evidence, we released the valuation allowance on the majority of our net operating losses and other deferred tax assets as of December 31, 2018.

Significant judgment is required in making these assessments to maintain or reverse our valuation allowances and, to the extent our future expectations change we would have to assess the recoverability of these deferred tax assets at that time. The determination to release the majority of our valuation allowances increased our net income by $1.56 billion, or $6.03 per share in 2018.

## RECENT ACCOUNTING PRONOUNCEMENTS

Refer to Note A, “Nature of Business and Accounting Policies,” in the accompanying notes to the consolidated financial statements for a discussion of recent accounting pronouncements and new accounting pronouncements adopted during 2020.

## ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As part of our investment portfolio, we own financial instruments that are sensitive to market risks. The investment portfolio is used to preserve our capital. None of these market risk-sensitive instruments are held for trading purposes. We do not have derivative financial instruments in our investment portfolio.

## Interest Rate Risk

We invest our cash in a variety of financial instruments, principally securities issued by the U.S. government and its agencies, investment-grade corporate bonds and commercial paper, and money market funds. These investments are denominated in U.S. Dollars. All of our interest-bearing securities are subject to interest rate risk and could decline in value if interest rates fluctuate, including potential fluctuations as a result of COVID-19. Substantially all of our investment portfolio consists of marketable securities with active secondary or resale markets to help ensure portfolio liquidity, and we have implemented guidelines limiting the term-to-maturity of our investment instruments. Due to the conservative nature of these instruments, we do not believe that we have a material exposure to interest rate risk. If interest rates were to increase or decrease by 1%, the fair value of our investment portfolio would increase or decrease by an immaterial amount.

We entered into a credit agreement in each of 2020 and 2019. Loans under these credit agreements bear interest, at our option, at either a base rate or a Eurocurrency rate, in each case plus an applicable margin based on our consolidated leverage ratio (the ratio of our total consolidated funded indebtedness to our consolidated EBITDA for the most recently completed four fiscal quarter period). Pursuant to the credit agreement that we entered into in 2019, the applicable margin on base rate loans ranges from 0.125% to 0.500% and the applicable margin on Eurocurrency loans ranges from 1.125% to 1.500%. Pursuant to the credit agreement that we entered into in 2020, the applicable margin on base rate loans ranges from 0.500% to 0.875% and the applicable margin on Eurocurrency loans ranges from 1.500% to 1.875%. We do not believe that changes in interest rates related to either credit agreement would have a material effect on our consolidated financial statements. As



of December 31, 2020, we had no principal or interest outstanding under either of our existing credit facilities. A portion of our “Interest expense” in 2021 will be dependent on whether, and to what extent, we borrow amounts under these existing facilities.

## Foreign Exchange Market Risk

As a result of our foreign operations, we face exposure to movements in foreign currency exchange rates, primarily the Euro and British Pound against the U.S. Dollar. Fluctuations in the global markets, including as a result of COVID-19, may have a positive or negative effect on our foreign exchange rate exposure. The current exposures arise primarily from cash, accounts receivable, intercompany receivables and payables, payables and accruals and inventories. Both positive and negative effects to our net revenues from international product sales from movements in exchange rates are partially mitigated by the natural, opposite effect that exchange rates have on our international operating costs and expenses.

We have a foreign currency management program with the objective of reducing the effect of exchange rate fluctuations on our operating results and forecasted revenues and expenses denominated in foreign currencies. We currently have cash flow hedges for the Euro, British Pound, Canadian Dollar and Australian Dollar related to a portion of our forecasted product revenues that qualify for hedge accounting treatment under U.S. GAAP. We do not seek hedge accounting treatment for our foreign currency forward contracts related to monetary assets and liabilities that impact our operating results. As of December 31, 2020, we held foreign exchange forward contracts that were designated as cash flow hedges with notional amounts totaling $1.1 billion representing a net liability of $63.5 million recorded on our consolidated balance sheet.

Although not predictive in nature, we believe a hypothetical 10% threshold reflects a reasonably possible near-term change in exchange rates. Assuming that the December 31, 2020 exchange rates were to change by a hypothetical 10%, the fair value recorded on our consolidated balance sheet related to our foreign exchange forward contracts that were designated as cash flow hedges as of December 31, 2020 would change by approximately $109.2 million. However, since these contracts hedge a specific portion of our forecasted product revenues denominated in certain foreign currencies, any change in the fair value of these contracts is recorded in “Accumulated other comprehensive loss” on our consolidated balance sheet and is reclassified to earnings in the same periods during which the underlying product revenues affect earnings. Therefore, any change in the fair value of these contracts that would result from a hypothetical 10% change in exchange rates would be entirely offset by the change in value associated with the underlying hedged product revenues resulting in no impact on our future anticipated earnings and cash flows with respect to the hedged portion of our forecasted product revenues.

The information required by this Item 8 is contained on pages F-1 through F-49 of this Annual Report on Form 10-K.

## ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Not applicable.



## ITEM 9A.CONTROLS AND PROCEDURES

(1) Evaluation of Disclosure Controls and Procedures. The Company’s chief executive officer and chief financial officer, after evaluating the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Annual Report on Form 10-K, have concluded that, based on such evaluation, the Company’s disclosure controls and procedures were effective. In designing and evaluating the disclosure controls and procedures, the Company’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Company’s management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

(2) Management’s Annual Report on Internal Control Over Financial Reporting. The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended, as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that:

- pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

- provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. In making this assessment, it used the criteria set forth in the Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment, the Company’s management has concluded that, as of December 31, 2020, the Company’s internal control over financial reporting is effective based on those criteria.

The Company’s independent registered public accounting firm, Ernst & Young LLP, issued an attestation report on the Company’s internal control over financial reporting. See Section 4 below.

(3) Changes in Internal Controls. During the quarter ended December 31, 2020, there were no changes in the Company’s internal control over financial reporting that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.



## (4) Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Vertex Pharmaceuticals Incorporated

## Opinion on Internal Control over Financial Reporting

We have audited Vertex Pharmaceuticals Incorporated’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Vertex Pharmaceuticals Incorporated (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2020 consolidated financial statements of the Company and our report dated February 11, 2021, expressed an unqualified opinion thereon.

## Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

## Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

# Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Vertex Pharmaceuticals Incorporated

## Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Vertex Pharmaceuticals Incorporated (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income, shareholders' equity and noncontrolling interest, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 11, 2021, expressed an unqualified opinion thereon.

## Adoption of New Accounting Standard

## ASU No. 2016-02

As discussed in Note A to the consolidated financial statements, the Company changed its method for lease accounting as a result of the adoption of ASU No. 2016-02, Leases (Topic 842), and the related amendments effective January 1, 2019.

## Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

## Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.



## Revenue recognition - Payor Mix Impact on Measuring Variable Consideration

As discussed in Note A to the Company’s consolidated financial statements, the Company records product sales at the net sales price, or “transaction price,” which requires the Company to make several significant estimates regarding the net sales price. The most significant estimates relate to government rebates, chargebacks, discounts and fees, collectively rebates. Due to the delay in receipt of claims by third-party payors, the Company estimates the percentage of prescriptions that will be covered by each third-party payor, which is referred to as the payor mix. Rebate accruals inclusive of estimated amounts due for claims not yet received or processed are recorded within accrued expenses on the Company’s consolidated balance sheet.

Auditing the measurement of the Company’s net product revenues was especially complex and judgmental due to the significant estimation required in determining the amount of consideration that will be collected net of estimates for payor rebates. In particular, the net sales price is affected by assumptions in payor behavior such as changes in payor mix, payor collections, current customer contractual requirements, and experience with ultimate collection from third-party payors.

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s revenue recognition process, including controls over the underlying assumptions and inputs used by management to estimate amounts due to third-party payors and the completeness and accuracy of the data used in the estimates. We also tested the Company’s controls to assess the completeness and accuracy of the current and historical data that supports the estimate.

Our audit procedures to test the Company’s recognition of net product revenues included, among others, assessing the methodology used to determine the estimate and testing the significant assumptions and the underlying data used by the Company in its analysis, which included historical claims data. To assess the payor mix assumptions we tested contracted rates, historical claims and payment data and related trends, and other relevant factors. We also assessed the historical accuracy of the Company’s estimates of third-party payor rebates.

We have served as the Company’s auditor since 2005.

# VERTEX PHARMACEUTICALS INCORPORATED
Notes to Consolidated Financial Statements

## A. Nature of Business and Accounting Policies

## Business

Vertex Pharmaceuticals Incorporated (“Vertex” or the “Company”) invests in scientific innovation to create transformative medicines for serious diseases. The Company’s business is focused on developing and commercializing therapies for the treatment of cystic fibrosis (“CF”) and advancing research and development programs in other indications. The Company’s marketed products are TRIKAFTA/KAFTRIO (elexacaftor/tezacaftor/ivacaftor and ivacaftor), SYMDEKO/SYMKEVI (tezacaftor in combination with ivacaftor), ORKAMBI (lumacaftor in combination with ivacaftor) and KALYDECO (ivacaftor), which are approved to treat people with CF who have specific mutations in their cystic fibrosis transmembrane conductance regulator (“CFTR”) gene.

As of December 31, 2020, the Company had cash, cash equivalents and marketable securities of $6.7 billion. The Company expects that cash flows from the sales of its products, together with its cash, cash equivalents and marketable securities, will be sufficient to fund its operations for at least the next twelve months.

The Company is subject to risks common to companies in its industry including, but not limited to, the dependence on revenues from its CF products, competition, uncertainty about clinical trial outcomes and regulatory approvals, uncertainties relating to pharmaceutical pricing and reimbursement, uncertainty related to international expansion, uncertain protection of proprietary technology, the need to comply with government regulations, share price volatility, dependence on collaborative relationships and potential product liability.

## Basis of Presentation

The accompanying consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), reflect the operations of (i) the Company, (ii) its wholly-owned subsidiaries and (iii) a consolidated variable interest entity (“VIE”). In 2018, the Company deconsolidated BioAxone Biosciences, Inc. (“BioAxone”), a VIE the Company had consolidated since 2014. As of December 31, 2020 and 2019, the Company did not have any consolidated VIEs. All material intercompany balances and transactions have been eliminated. The Company operates in one segment, pharmaceuticals. Please refer to Note Q, “Segment Information,” for enterprise-wide disclosures regarding the Company’s revenues, major customers and long-lived assets by geographic area. The Company has reclassified certain items from the prior year’s consolidated financial statements to conform to the current year’s presentation.

## Use of Estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the amounts of revenues and expenses during the reported periods. Significant estimates in these consolidated financial statements have been made in connection with (i) determining the transaction price of revenues, (ii) accounting for acquisitions, including intangible assets, goodwill and contingent consideration and (iii) evaluating deferred tax asset valuation allowances and the provision for income taxes. The Company bases its estimates on historical experience and various other assumptions, including in certain circumstances future projections that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become known.

# Notes to Consolidated Financial Statements (Continued)

## Revenue Recognition

The Company recognizes revenue when a customer obtains control of promised goods or services. The Company records the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. The Company applies the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

The Company only applies the five-step model to contracts when it is probable that it will collect the consideration to which it is entitled in exchange for the goods or services that it transfers to the customer. Once a contract is determined to be within the scope of Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”) at contract inception, the Company reviews the contract to determine which performance obligations it must deliver and which of these performance obligations are distinct. The Company recognizes as revenue the amount of the transaction price that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied. Generally, the Company’s performance obligations are transferred to customers at a point in time, typically upon delivery.

## Product Revenues, Net

The Company sells its products principally to a limited number of specialty pharmacy and specialty distributors in the United States (“U.S.”), which account for the largest portion of its total revenues, and makes international sales primarily to specialty distributors and retail chains, as well as hospitals and clinics, many of which are government-owned or supported (collectively, its “Customers”). The Company’s Customers in the U.S. subsequently resell the products to patients and health care providers. The Company recognizes net product revenues from sales when the Customers obtain control of the Company’s products, which typically occurs upon delivery to the Customer. The Company’s payment terms are approximately 30 days in the U.S. and consistent with prevailing practice in international markets.

Revenues from product sales are recorded at the net sales price, or “transaction price,” which includes estimates of variable consideration that result from (a) invoice discounts for prompt payment and distribution fees, (b) government and private payor rebates, chargebacks, discounts and fees and (c) costs of copy assistance programs for patients, as well as other incentives for certain indirect customers. Reserves are established for the estimates of variable consideration based on the amounts earned or to be claimed on the related sales. The reserves are classified as reductions to “Accounts receivable, net” if payable to a Customer or “Accrued expenses” if payable to a third-party. Where appropriate, the Company utilizes the expected value method to determine the appropriate amount for estimates of variable consideration based on factors such as the Company’s historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. The amount of variable consideration that is included in the transaction price may be constrained and is included in net product revenues only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary from the Company’s estimates, the Company adjusts these estimates, which would affect net product revenue and earnings in the period such variances become known.

Invoice Discounts and Distribution Fees: The Company generally provides invoice discounts on product sales to its Customers for prompt payment and pays fees for distribution services, such as fees for certain data that Customers provide to the Company. The Company estimates that, based on its experience, its Customers will earn these discounts and fees, and deducts the full amount of these discounts and fees from its gross product revenues and accounts receivable at the time such revenues are recognized.

Rebates, Chargebacks, Discounts and Fees: The Company contracts with government agencies (its “Third-party Payors”) so that products will be eligible for purchase by, or partial or full reimbursement from, such Third-party Payors. The Company estimates the rebates, chargebacks, discounts and fees it will provide to Third-party Payors and deducts these estimated amounts from its gross product revenues at the time the revenues are recognized. For each product, the Company estimates the aggregate rebates, chargebacks and discounts that it will provide to Third-party Payors based upon (i) the Company’s contracts with these Third-party Payors, (ii) the government-mandated discounts and fees



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

applicable to government-funded programs, (iii) information obtained from the Company’s Customers and other third-party data regarding the payor mix for such product and (iv) historical experience.

Other Incentives: Other incentives that the Company offers include co-pay mitigation rebates provided by the Company to commercially insured patients who have coverage and who reside in states that permit co-pay mitigation programs. Based upon the terms of the Company’s co-pay mitigation programs, the Company estimates average co-pay mitigation amounts for each of its products in order to establish appropriate accruals.

The Company makes significant estimates and judgments that materially affect its recognition of net product revenues. The Company adjusts its estimated rebates, chargebacks and discounts based on new information, including information regarding actual rebates, chargebacks and discounts for its products, as it becomes available. Claims by third-party payors for rebates, chargebacks and discounts frequently are submitted to the Company significantly after the related sales, potentially resulting in adjustments in the period in which the new information becomes known. The Company’s credits to product revenue related to prior period sales have not been significant and primarily related to rebates and discounts.

The Company excludes taxes collected from Customers relating to product sales and remitted to governmental authorities from revenues.

## Contract Liabilities

The Company recorded contract liabilities of $191.5 million and $62.3 million as of December 31, 2020 and 2019, respectively, related to annual contracts with government-owned and supported customers in international markets that limit the amount of annual reimbursement the Company can receive. Upon exceeding the annual reimbursement amount, products are provided free of charge, which is a material right. These contracts include upfront payments and fees. The Company defers a portion of the consideration received for shipments made up to the annual reimbursement limit as a portion of “Other current liabilities.” The deferred amount is recognized as revenue when the free products are shipped. The Company’s product revenue contracts include performance obligations that are one year or less.

The Company’s contract liabilities at the end of each fiscal year relate to contracts with annual reimbursement limits in international markets in which the annual period associated with the contract is not the same as the Company’s fiscal year. In these markets the Company recognizes revenues related to performance obligations satisfied in previous years; however, these revenues do not relate to any performance obligations that were satisfied more than 12 months prior to the beginning of the current year. During the years ended December 31, 2020, 2019 and 2018, the Company recorded $62.3 million, $24.9 million and $1.7 million, respectively, of revenues that were recorded as contract liabilities at the beginning of the year.

## French Early Access Programs

In 2015, the Company began distributing ORKAMBI through early access programs in France and remained engaged in reimbursement discussions with the French government until November 2019, when the Company reached an agreement with the French government for ORKAMBI, including ORKAMBI distributed through early access programs. From the time the Company began distributing ORKAMBI through early access programs in France, it expected the difference between the amounts collected based on the invoiced amount and the final amount for ORKAMBI distributed through early access programs would be returned to the French government. As a result, the Company had classified a refund liability related to the early access programs in France within “Accrued expenses” on its consolidated balance sheets.

From the first quarter of 2018 through the third quarter of 2019, the Company recognized net product revenues for ORKAMBI sales in France under the early access programs based on a transaction price that reflected the Company’s estimate of consideration it expected to retain that would not be subject to a significant reversal in amounts recognized. When determining if variable consideration should be constrained, the Company considers whether there are factors outside its control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue.

Upon reaching an agreement with the French government for ORKAMBI, including ORKAMBI distributed through early access programs in November 2019, the Company updated the transaction price to reflect the final amount for ORKAMBI distributed through early access programs. As a result, the Company recognized net product revenues of



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

$155.8 million related to prior period ORKAMBI early access program sales in the fourth quarter of 2019 because the updated transaction price for ORKAMBI distributed through these programs exceeded the Company’s previous estimate of the consideration it expected to retain that would not be subject to a significant reversal in amounts recognized. The Company paid the final amount due to the French government in 2020.

## Collaborative and Royalty Revenues

The Company has not recorded significant collaborative and royalty revenues during the three years ended December 31, 2020; however, in future periods, it may recognize collaborative revenues generated through collaborative research, development and/or commercialization agreements. The terms of these agreements typically include payment to the Company related to one or more of the following: nonrefundable, upfront license fees; development and commercial milestones; funding of research and/or development activities; and royalties on net sales of licensed products. Revenue is recognized upon satisfaction of a performance obligation by transferring control of a good or service to the collaborator.

For each collaborative research, development and/or commercialization agreement that results in revenue, the Company identifies all material performance obligations, which may include a license to intellectual property and know-how, research and development activities and/or transition activities. In order to determine the transaction price, in addition to any upfront payment, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. The Company constrains (reduces) the estimate of variable consideration such that it is probable that a significant reversal of previously recognized revenue will not occur throughout the life of the contract. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required.

Once the estimated transaction price is established, amounts are allocated to the performance obligations that have been identified. The transaction price is generally allocated to each separate performance obligation on a relative standalone selling price basis. In order to account for these agreements, the Company must develop assumptions that require judgment to determine the standalone selling price, which may include (i) the probability of obtaining marketing approval for the drug candidate, (ii) estimates regarding the timing of and the expected costs to develop and commercialize the drug candidate, (iii) estimates of future cash flows from potential product sales with respect to the drug candidate and (iv) appropriate discount and tax rates. Standalone selling prices used to perform the initial allocation are not updated after contract inception. The Company does not include a financing component to its estimated transaction price at contract inception unless it estimates that certain performance obligations will not be satisfied within one year.

Upfront License Fees: If a license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in an arrangement, the Company recognizes revenue from the related nonrefundable, upfront license fees based on the relative standalone selling price prescribed to the license compared to the total selling price of the arrangement. The revenue is recognized when the license is transferred to the collaborator and the collaborator is able to use and benefit from the license. For licenses that are not distinct from other obligations identified in the arrangement, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time. If the combined performance obligation is satisfied over time, the Company applies an appropriate method of measuring progress for purposes of recognizing revenue from nonrefundable, upfront license fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

Development and Regulatory Milestone Payments: Depending on facts and circumstances, the Company may conclude that it is appropriate to include certain milestones in the estimated transaction price or that it is appropriate to fully constrain the milestones. A milestone payment is included in the transaction price in the reporting period that the Company concludes that it is probable that recording revenue in the period will not result in a significant reversal in amounts recognized in future periods. This may result in revenues from certain milestones and a corresponding contract asset being recorded in a reporting period before the milestone is achieved. Milestone payments that have not been included in the transaction price to date are fully constrained until the Company concludes that their achievement is probable and that recognition of the related revenue will not result in a significant reversal in amounts recognized in future periods. The Company re-evaluates the probability of achievement of such development milestones and any related constraint each reporting period and adjusts its estimate of the overall transaction price, including the amount of collaborative revenue that it has recorded, if necessary.

Research and Development Activities/Transition Services: If the Company is entitled to reimbursement from its collaborators for specified research and development expenses, it accounts for the related services that it provides as separate performance obligations if it determines that these services represent a material right. The Company also determines whether the reimbursement of research and development expenses should be accounted for as collaborative revenues or an offset to research and development expenses in accordance with the provisions of gross or net revenue presentation. The Company recognizes the corresponding revenues or records the corresponding offset to research and development expenses as it satisfies the related performance obligations.

Sales-based Milestone and Royalty Payments: The Company’s collaborators may be required to pay the Company sales-based milestones or royalties on future sales of commercial products. The Company recognizes revenues related to sales-based milestone and royalties upon the later to occur of (i) achievement of the collaborator’s underlying sales or (ii) satisfaction of any performance obligation(s) related to these sales, in each case assuming the license to the Company’s intellectual property is deemed to be the predominant item to which the sales-based milestones and/or royalties relate.

## Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of money market funds and marketable securities. The Company places these investments with highly rated financial institutions, and, by policy, limits the amounts of credit exposure to any one financial institution. These amounts at times may exceed federally insured limits. The Company also maintains a foreign currency hedging program that includes foreign currency forward contracts with several counterparties. The Company has not experienced any credit losses related to these financial instruments and does not believe it is exposed to any significant credit risk related to these instruments.

The Company also is subject to credit risk from its accounts receivable related to its product sales and collaborators. The Company evaluates the creditworthiness of each of its customers and has determined that all of its material customers are creditworthy. To date, the Company has not experienced significant losses with respect to the collection of its accounts receivable. The Company believes that its allowances, which are not significant to its consolidated financial statements, are adequate at December 31, 2020. Please refer to Note Q, “Segment Information,” for further information.

## Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.

## Marketable Securities

As of December 31, 2020, the Company’s marketable securities consisted of investments in available-for-sale debt securities and corporate equity securities with readily determinable fair values. The Company classifies marketable securities available to fund current operations as current assets on its consolidated balance sheets. Marketable securities are classified as long-term assets on the consolidated balance sheets if (i) they have been in an unrealized loss position for longer than one year and (ii) the Company has the ability and intent to hold them (a) until the carrying value is recovered and (b) such holding



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

period may be longer than one year. The Company’s marketable securities are stated at fair value. The fair value of these securities is based on quoted prices for identical or similar assets.

The Company records unrealized gains (losses) on available-for-sale debt securities as a component of “Accumulated other comprehensive loss,” which is a separate component of shareholders’ equity on its consolidated balance sheet, until such gains and losses are realized. Realized gains and losses, if any, are determined using the specific identification method.

The Company records changes in the fair value of its investments in corporate equity securities to “Other income (expense), net” in its consolidated statements of operations. Realized gains and losses, which are also included in “Other income (expense), net,” are determined on an original weighted-average cost basis.

The Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) as of January 1, 2020, which did not have a significant impact on its consolidated financial statements. For available-for-sale debt securities in unrealized loss positions, ASU 2016-13 requires the Company to record an allowance for credit losses using an expected loss model, which replaces the incurred loss model required under the previous guidance. A credit loss is limited to the amount by which the amortized cost of an investment exceeds its fair value. A previously recognized credit loss may be decreased in subsequent periods if the Company’s estimate of fair value for the investment increases. To determine whether to record a credit loss, the Company considers issuer specific credit ratings and historical losses as well as current economic conditions and its expectations for future economic conditions.

## Accounts Receivable

The Company deducts invoice discounts for prompt payment and fees for distribution services from its accounts receivable based on its experience that the Company’s Customers will earn these discounts and fees. The Company’s estimates for its allowance for credit losses, which has not been significant to date, is determined based on existing contractual payment terms, historical payment patterns, current economic conditions and the Company’s expectation for future economic conditions.

## Stock-based Compensation Expense

The Company expenses the fair value of employee restricted stock units and other forms of stock-based employee compensation over the associated employee service period on a straight-line basis. Stock-based compensation expense is determined based on the fair value of the award at the grant date and is adjusted each period to reflect actual forfeitures and the outcomes of certain performance conditions.

For awards with performance conditions in which the award does not vest unless the performance condition is met, the Company recognizes expense if, and to the extent that, the Company estimates that achievement of the performance condition is probable. If the Company concludes that vesting is probable, it recognizes expense from the date it reaches this conclusion through the estimated vesting date.

The Company provides to employees who have rendered a certain number of years of service to the Company and meet certain age requirements, partial or full acceleration of vesting of these equity awards, subject to certain conditions including a notification period, upon a termination of employment other than for cause. Approximately 5% of the Company’s employees were eligible for partial or full acceleration of any of their equity awards as of December 31, 2020. The Company recognizes stock-based compensation expense related to these awards over a service period reflecting qualified employees’ eligibility for partial or full acceleration of vesting.

## Research and Development Expenses

The Company expenses as incurred all research and development expenses, including amounts funded by research and development collaborations. The Company capitalizes nonrefundable advance payments made by the Company for research and development activities and expenses the payments as the related goods are delivered or the related services are performed.



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

Research and development expenses are comprised of costs incurred by the Company in performing research and development activities, including salary and benefits; stock-based compensation expense; outsourced services and other direct expenses, including clinical trial and pharmaceutical development costs; collaborative payments; and infrastructure costs, including facilities costs and depreciation expense.

## Inventories

The Company values its inventories at the lower-of-cost or net realizable value. The Company determines the cost of its inventories, which includes amounts related to materials and manufacturing overhead, on a first-in, first-out basis. The Company performs an assessment of the recoverability of capitalized inventory during each reporting period, and writes down any excess and obsolete inventories to their net realizable value in the period in which the impairment is first identified. Shipping and handling costs incurred for inventory purchases are capitalized and recorded upon sale in “Cost of sales” in the consolidated statements of operations. Shipping and handling costs incurred for product shipments are recorded as incurred in “Cost of sales” in the consolidated statements of operations.

The Company capitalizes inventories produced in preparation for initiating sales of a drug candidate when the related drug candidate is considered to have a high likelihood of regulatory approval and the related costs are expected to be recoverable through sales of the inventories. In determining whether or not to capitalize such inventories, the Company evaluates, among other factors, information regarding the drug candidate’s safety and efficacy, the status of regulatory submissions and communications with regulatory authorities and the outlook for commercial sales, including the existence of current or anticipated competitive drugs and the availability of reimbursement. In addition, the Company evaluates risks associated with manufacturing the drug candidate and the remaining shelf-life of the inventories.

## Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation. Depreciation expense is recorded using the straight-line method over the estimated useful life of the related asset generally as follows:

<table><tr><td>Description</td><td>Estimated Useful Life</td></tr><tr><td>Buildings and improvements</td><td>15 to 40 years</td></tr><tr><td>Furniture and equipment</td><td>7 to 10 years</td></tr><tr><td>Leasehold improvements; assets under finance leases</td><td>The shorter of the useful life of the assets or the estimated remaining term of the associated lease</td></tr><tr><td>Computers and software</td><td>3 to 5 years</td></tr></table>

Maintenance and repairs to an asset that do not improve or extend its life are charged to operations. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the Company’s consolidated statements of operations. The Company performs an assessment of the fair value of the assets if indicators of impairment are identified during a reporting period and records the assets at the lower of the net book value or the fair value of the assets.

The Company capitalizes internal costs incurred to develop software for internal use during the application development stage. Amortization of capitalized internally developed software costs is recorded in depreciation expense over the useful life of the related asset.

## Leases

The Company adopted ASU 2016-02, Leases (Topic 842) (“ASC 842”), as of January 1, 2019. Under ASC 842, the Company determines whether the arrangement contains a lease at the inception of an arrangement. If a lease is identified in an arrangement, the Company recognizes a right-of-use asset and liability on its consolidated balance sheet and determines whether the lease should be classified as a finance or operating lease. The Company does not recognize assets or liabilities for leases with lease terms of less than 12 months.

A lease qualifies as a finance lease if any of the following criteria are met at the inception of the lease: (i) there is a transfer of ownership of the leased asset to the Company by the end of the lease term, (ii) the Company holds an option to purchase the leased asset that it is reasonably certain to exercise, (iii) the lease term is for a major part of the remaining



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

economic life of the leased asset, (iv) the present value of the sum of lease payments equals or exceeds substantially all of the fair value of the leased asset, or (v) the nature of the leased asset is specialized to the point that it is expected to provide the lessor no alternative use at the end of the lease term. All other leases are recorded as operating leases.

Finance and operating lease assets and liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term using the discount rate implicit in the lease. If the rate implicit is not readily determinable, the Company utilizes its incremental borrowing rate at the lease commencement date. Operating lease assets are further adjusted for prepaid or accrued lease payments. Operating lease payments are expensed using the straight-line method as an operating expense over the lease term. Finance lease assets are amortized to depreciation expense using the straight-line method over the shorter of the useful life of the related asset or the lease term. Finance lease payments are bifurcated into (i) a portion that is recorded as imputed interest expense and (ii) a portion that reduces the finance liability associated with the lease.

The Company does not separate lease and non-lease components when determining which lease payments to include in the calculation of its lease assets and liabilities. Variable lease payments are expensed as incurred. If a lease includes an option to extend or terminate the lease, the Company reflects the option in the lease term if it is reasonably certain it will exercise the option.

Finance leases are recorded in “Property and equipment, net,” “Other current liabilities” and “Long-term finance lease liabilities” and operating leases are recorded in “Operating lease assets,” “Other current liabilities” and “Long-term operating lease liabilities” on the Company’s consolidated balance sheet.

In 2018, prior to the adoption of ASC 842 on January 1, 2019, the Company applied build-to-suit accounting and was the deemed owner of its leased corporate headquarters in Boston and research site in San Diego, for which it was recognizing depreciation expense over the buildings' useful lives and imputed interest on the corresponding construction financing lease obligations.

## Income Taxes

Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the income tax bases of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. On a periodic basis, the Company reassesses the valuation allowance on its deferred income tax assets weighing positive and negative evidence to assess the recoverability of its deferred tax assets. The Company includes, among other things, its recent financial performance and its future projections in this periodic assessment.

The Company records liabilities related to uncertain tax positions by prescribing a minimum recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not believe any such uncertain tax positions currently pending will have a material adverse effect on its consolidated financial statements.

## Variable Interest Entities

The Company reviews each collaboration agreement pursuant to which it licenses assets owned by a collaborator in order to determine whether or not it has a variable interest via the license agreement with the collaborator and if the variable interest is a variable interest in the collaborator as a whole. In assessing whether the Company has a variable interest in the collaborator as a whole, the Company considers and makes judgments regarding the purpose and design of the entity, the value of the licensed assets to the collaborator, the value of the collaborator's total assets and the significant activities of the collaborator. If the Company has a variable interest in the collaborator as a whole, the Company assesses whether or not the Company is the primary beneficiary of that VIE based on a number of factors, including (i) which party has the power to direct the activities that most significantly affect the VIE's economic performance, (ii) the parties' contractual rights and responsibilities pursuant to the collaboration agreement and (iii) which party has the obligation to absorb losses of or the right to receive benefits from the VIE that could be significant to the VIE. If the Company determines it is the primary beneficiary of a VIE at the onset of the collaboration agreement, the collaboration is treated as a business combination and the Company consolidates the financial statements of the VIE into the Company's consolidated financial statements. On a quarterly basis,



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

the Company evaluates whether it continues to be the primary beneficiary of any consolidated VIEs. If the Company determines that it is no longer the primary beneficiary of a consolidated VIE, or no longer has a variable interest in the VIE, it deconsolidates the VIE in the period that the determination is made.

## Fair Value of In-process Research and Development Assets and Contingent Payments

The present-value models the Company uses to estimate the fair values of in-process research and development assets and contingent payments pursuant to collaborations and acquisitions incorporate significant assumptions.

The Company’s discounted cash flow models pertaining to in-process research and development assets include: (i) assumptions regarding the probability of obtaining marketing approval for a drug candidate; (ii) the timing of and the expected costs to develop and commercialize a drug candidate; (iii) estimates of future cash flows from potential product sales with respect to a drug candidate; and (iv) appropriate discount and tax rates.

The Company bases its estimates of the probability of achieving the milestones relevant to the fair value of contingent payments, which could include milestone, royalty and option payments, on industry data. Estimates included in the discounted cash flow models pertaining to contingent payments also include: (i) estimate regarding the timing of the relevant development and commercial milestones and royalties, (ii) and appropriate discount rates. Please refer to Note D, “Fair Value Measurements,” for further information.

## In-process Research and Development Assets

The Company records the fair value of in-process research and development assets as of the transaction date of a business combination. Each of these assets is accounted for as an indefinite-lived intangible asset and is maintained on the Company's consolidated balance sheet until either the project underlying it is completed or the asset becomes impaired. If the asset becomes impaired or is abandoned, the carrying value of the related intangible asset is written down to its fair value, and an impairment charge is recorded in the period in which the impairment occurs. If a project is completed, the carrying value of the related intangible asset is amortized as a part of "Cost of sales" over the remaining estimated life of the asset beginning in the period in which the project is completed. In-process research and development assets are tested for impairment on an annual basis as of October 1, and more frequently if indicators are present or changes in circumstances suggest that impairment may exist.

In-process research and development that is acquired in a transaction that does not qualify as a business combination under U.S. GAAP and that does not have an alternative future use is recorded to “Research and development expenses” in the period in which it is acquired.

## Goodwill

The difference between the purchase price and the fair value of assets acquired and liabilities assumed in a business combination is allocated to goodwill. Goodwill is evaluated for impairment on an annual basis as of October 1, and more frequently if indicators are present or changes in circumstances suggest that impairment may exist. As noted in Basis of Presentation above, the Company has one operating segment, pharmaceuticals, which is its only reporting unit.

## Deconsolidation

Upon the occurrence of certain events and on a regular basis, the Company evaluates whether it no longer has a controlling interest in its subsidiaries, including consolidated VIEs. If the Company determines it no longer has a controlling interest, the subsidiary is deconsolidated. The Company records a gain or loss on deconsolidation based on the difference on the deconsolidation date between (i) the aggregate of (a) the fair value of any consideration received, (b) the fair value of any retained noncontrolling investment in the former subsidiary and (c) the carrying amount of any noncontrolling interest in the subsidiary being deconsolidated, less (ii) the carrying amount of the former subsidiary's assets and liabilities.

## Discontinued Operations

The Company assesses whether a deconsolidation is required to be presented as discontinued operations in its consolidated financial statements on the deconsolidation date. This assessment is based on whether or not the deconsolidation



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

represents a strategic shift that has or will have a major effect on the Company’s operations or financial results. If the Company determines that a deconsolidation requires presentation as a discontinued operation on the deconsolidation date, or at any point during the one year period following such date, it will present the former subsidiary as a discontinued operation in current and comparative period financial statements.

## Embedded Derivatives

Embedded derivatives are required to be bifurcated from the host instruments and recorded at fair value if the derivatives are not clearly and closely related to the host instruments on the date of issuance. The Company did not have any material embedded derivatives that required bifurcation recorded on its consolidated balance sheets as of December 31, 2020 and 2019, respectively.

## Hedging Activities

The Company recognizes the fair value of hedging instruments that are designated and qualify as hedging instruments pursuant to U.S. GAAP, foreign currency forward contracts, as either assets or liabilities on the consolidated balance sheets. Changes in the fair value of these instruments are recorded each period in “Accumulated other comprehensive loss” as unrealized gains and losses until the forecasted underlying transaction occurs. Unrealized gains and losses on these foreign currency forward contracts are included in “Prepaid expenses and other current assets” or “Other assets,” and “Other current liabilities” or “Other long-term liabilities,” respectively, on the Company’s consolidated balance sheets depending on the remaining period until their contractual maturity. Realized gains and losses for the effective portion of such contracts are recognized in “Product revenues, net” in the consolidated statement of operations in the same period that it recognizes the product revenues that were impacted by the hedged foreign exchange rate changes. The Company classifies the cash flows from hedging instruments in the same category as the cash flows from the hedged items.

Certain of the Company’s hedging instruments are subject to master netting arrangements to reduce the risk arising from such transactions with its counterparties. The Company presents unrealized gains and losses on its foreign currency forward contracts on a gross basis within its consolidated balance sheets.

The Company also enters into foreign currency forward contracts with contractual maturities of less than one month designed to mitigate the effect of changes in foreign exchange rates on monetary assets and liabilities including intercompany balances. These contracts are not designated as hedging instruments pursuant to U.S. GAAP. Realized gains and losses for such contracts are recognized in “Other income (expense), net” in the consolidated statement of operations each period.

## Restructuring Expenses

The Company records costs and liabilities associated with exit and disposal activities based on estimates of fair value in the period the liabilities are incurred. The Company’s exit and disposal activities have primarily been associated with the Company’s facilities, but also have included the termination of employees in some cases. The Company’s initial estimate of its liabilities for net ongoing costs associated with its facility obligations are recorded at fair value on the cease use date. On a quarterly basis, the Company evaluates and adjusts these liabilities as appropriate for changes in circumstances. Changes to the Company’s estimate of these liabilities are recorded as additional restructuring expenses (credits). These costs are included in “Restructuring expense (income)” on the Company’s consolidated statements of operations.

## Comprehensive Income

Comprehensive income consists of net income and other comprehensive income (loss), which includes foreign currency translation adjustments and unrealized gains and losses on foreign currency forward contracts and certain marketable securities. For purposes of comprehensive income disclosures, the Company records provisions for or benefits from income taxes related to the unrealized gains and losses on foreign currency forward contracts and certain marketable securities. The Company does not record provisions for or benefits from income taxes related to the cumulative translation adjustment, as the Company intends to permanently reinvest undistributed earnings in its foreign subsidiaries.



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

## Foreign Currency Translation and Transactions

The majority of the Company’s operations occur in entities that have the U.S. dollar denominated as their functional currency. The assets and liabilities of the Company’s entities with functional currencies other than the U.S. dollar are translated into U.S. dollars at rates of exchange in effect at the end of the year. Revenue and expense amounts for these entities are translated using the average exchange rates for the period. Net unrealized gains and losses resulting from foreign currency translation are included in “Accumulated other comprehensive loss.” Net foreign currency exchange transaction losses, which are included in “Other income (expense), net” on the Company’s consolidated statement of operations, were $16.1 million, $5.2 million and $1.1 million for 2020, 2019 and 2018, respectively. These net foreign currency exchange losses are presented net of the impact of the foreign currency forward contracts designed to mitigate their effect on the Company’s consolidated statement of operations.

## Net Income Per Share Attributable to Vertex Common Shareholders

Basic and diluted net income per share attributable to Vertex common shareholders are presented in conformity with the two-class method required for participating securities. Shares of unvested restricted stock granted under the Company’s Amended and Restated 2006 Stock and Option Plan had the non-forfeitable right to receive dividends on an equal basis with other outstanding common stock. As a result, these unvested shares of restricted stock were considered participating securities under the two-class method. In 2020 and 2019, the Company did not have a significant amount of restricted stock outstanding under this plan: therefore, the two-class method did not impact its basic and diluted net income per share attributable to Vertex common shareholders for the years ended December 31, 2020 and 2019.

Under the two-class method, earnings are allocated to (i) Vertex common shares, excluding unvested restricted stock, and (ii) participating securities, based on their respective weighted-average shares outstanding for the period. Potentially dilutive shares result from the assumed exercise of outstanding stock options (the proceeds of which are then assumed to have been used to repurchase outstanding stock using the treasury-stock method).

Basic net income per share attributable to Vertex common shareholders is based upon the weighted-average number of common shares outstanding during the period, excluding restricted stock that had been issued but had not yet vested, if any. Diluted net income per share attributable to Vertex common shareholders is based upon the weighted-average number of common shares outstanding during the period plus additional weighted-average common equivalent shares outstanding during the period when the effect is dilutive.

## Recently Adopted Accounting Standards

## Internal-Use Software

In 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which clarifies the accounting for implementation costs in cloud computing arrangements. ASU 2018-15 became effective on January 1, 2020. The adoption of ASU 2018-15 resulted in an insignificant amount of additional assets recorded on the Company’s consolidated balance sheet.

## Fair Value Measurement

In 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which modifies the disclosure requirements for fair value measurements. ASU 2018-13 became effective on January 1, 2020. The Company adoption of ASU 2018-13 resulted in additional disclosures related to the Company’s Level 3 inputs. Please refer to Note D, “Fair Value Measurements,” for further information.

## Credit Losses

In 2016, the FASB issued ASU 2016-13, which requires entities to record expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities in unrealized loss positions, ASU 2016-13 requires allowances to be



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

recorded instead of reducing the amortized cost of the investment. ASU 2016-13 became effective on January 1, 2020. The adoption of ASU 2016-13 did not have a significant impact on the Company’s consolidated financial statements.

## Leases

On January 1, 2019, the Company adopted ASC 842 using the modified-retrospective method. Until December 31, 2018, the Company applied build-to-suit accounting and was the deemed owner of its leased corporate headquarters in Boston and research site in San Diego, for which it was recognizing depreciation expense over the buildings' useful lives and imputed interest on the corresponding construction financing lease obligations. Under the amended guidance that became effective January 1, 2019, the Company accounts for these buildings as finance leases, resulting in increased depreciation expense over the respective lease terms of approximately 15 years, which are significantly shorter than the buildings' useful lives of 40 years. The amended guidance also results in a reduction in imputed interest expense in the initial years of each finance lease term. As of January 1, 2019, the Company recorded a cumulative effect adjustment to increase its “Accumulated deficit” by $40.3 million related to the adjustments to its build-to-suit leases. Please refer to “Leases” above for further information.

## Revenue Recognition

On January 1, 2018, the Company adopted ASC 606, using the modified retrospective adoption method for all contracts that were not completed as of the date of adoption. Based on the Company’s review of existing customer contracts as of January 1, 2018, the Company concluded that the only significant impact that the adoption of ASC 606 had on its consolidated financial statements related to shipments of ORKAMBI under early access programs in France. Prior to the adoption of ASC 606, the Company did not recognize revenue on the proceeds received from sales of ORKAMBI under early access programs in France because the price was not fixed or determinable based on the status of ongoing pricing discussions. As of January 1, 2018, the Company recorded a cumulative effect adjustment to its accumulated deficit of $8.3 million related to the adoption of ASC 606, which primarily represented the Company’s estimated amount of consideration it expected to retain related to these shipments that would not be subject to a significant reversal in amounts recognized, net of costs previously deferred related to these shipments.

## Equity Investments

On January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”), using the required modified-retrospective adoption method. Under ASU 2016-01, equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of an investee) are measured at fair value with changes in fair value recognized in net income. As of January 1, 2018, the Company held publicly traded equity investments and equity investments accounted for under the cost method. As a result, in 2018, the Company recorded a $25.1 million cumulative effect adjustment to “Accumulated deficit” related to its publicly traded equity investments equal to the unrealized gain, net of tax, that was recorded in “Accumulated other comprehensive loss” as of December 31, 2017.

## Recently Issued Accounting Standards

## Income Taxes

In 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) (“ASU 2019-12”), which simplifies the accounting for income taxes. ASU 2019-12 was effective on January 1, 2021. The Company does not expect the adoption of ASU 2019-12 to have a significant impact on its consolidated financial statements.

## B. Collaborative Arrangements

The Company has entered into numerous agreements pursuant to which it collaborates with third parties on research, development and commercialization programs, including in-license and out-license agreements.

## In-license Agreements

The Company has entered into a number of license agreements in order to advance and obtain access to technologies and services related to its research and early-development activities. The Company is generally required to make an upfront payment upon execution of the license agreement; development, regulatory and commercialization milestones payments upon the achievement of certain product research, development and commercialization objectives; and royalty payments on future sales, if any, of commercial products resulting from the collaboration.

Pursuant to the terms of its in-license agreements, the Company’s collaborators typically lead the discovery efforts and the Company leads all preclinical, development and commercialization activities associated with the advancement of any drug candidates and funds all expenses.

The Company typically can terminate its in-license agreements by providing advance notice to its collaborators; the required length of notice is dependent on whether any product developed under the license agreement has received marketing approval. The Company’s license agreements may be terminated by either party for a material breach by the other, subject to notice and cure provisions. Unless earlier terminated, these license agreements generally remain in effect until the date on which the royalty term and all payment obligations with respect to all products in all countries have expired.

## CRISPR Therapeutics AG

In 2015, the Company entered into a strategic collaboration, option and license agreement (the "CRISPR Agreement") with CRISPR Therapeutics AG and its affiliates ("CRISPR") to collaborate on the discovery and development of potential new treatments aimed at the underlying genetic causes of human diseases using CRISPR-Cas9 gene-editing technology. The Company had the exclusive right to license certain targets. In the fourth quarter of 2019, the Company paid an aggregate of $30.0 million to exclusively license three CRISPR-Cas9-based targets, including CF, pursuant to the CRISPR Agreement. The Company recorded the $30.0 million total option payment to "Research and development expenses" in the fourth quarter of 2019. For each of the three targets that the Company elected to license, CRISPR has the potential to receive up to an additional $410.0 million in development, regulatory and commercial milestones as well as royalties on net product sales.

In 2017, the Company entered into a co-development and co-commercialization agreement with CRISPR pursuant to the terms of the CRISPR Agreement, under which the Company and CRISPR are co-developing and will co-commercialize CTX001 (the "CTX001 Co-Co Agreement") for the treatment of hemoglobinopathies, including treatments for sickle cell disease and beta thalassemia. As part of the collaboration, the Company and CRISPR share equally all development costs and potential worldwide revenues related to potential hemoglobinopathy treatments. The Company concluded that the CTX001 Co-Co Agreement is a cost-sharing arrangement, which results in the net impact of the arrangement being recorded in "Research and development expenses" in its consolidated statements of operations. During the years ended December 31, 2020, 2019 and 2018, the net expense related to the CTX001 Co-Co Agreement was $50.6 million, $30.1 million and $19.7 million, respectively.

In July 2019, the Company entered into a separate strategic collaboration and license agreement (the "CRISPR DMD/DM1 Agreement") with CRISPR. Pursuant to this agreement, the Company received an exclusive worldwide license to CRISPR's existing and future intellectual property for Duchenne muscular dystrophy ("DMD") and myotonic dystrophy type 1 ("DM1") and the Company made an upfront payment of $175.0 million to CRISPR. The Company concluded that it did not have any alternative future use for the acquired in-process research and development and recorded the upfront payment to "Research and development expenses" in the third quarter of 2019. In 2020, the Company recorded $25.0 million to "Research and development expenses" related to a pre-clinical milestone earned by CRISPR under the CRISPR DMD/DM1 Agreement. CRISPR has the potential to receive up to an additional $800.0 million in research, development, regulatory and commercial milestones for the DMD and DM1 programs as well as royalties on net product sales. CRISPR has the option to co-develop and co-commercialize all DM1 products globally and forego the milestones and royalties associated with the



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

DM1 program. The Company funds all expenses associated with the collaboration except for research costs for specified guide RNA research conducted by CRISPR, which the Company and CRISPR share equally.

## Kymera Therapeutics Inc.

In May 2019, the Company entered into a strategic research and development collaboration agreement with Kymera Therapeutics Inc. ("Kymera") to advance small molecule protein degraders against multiple targets. Kymera's proprietary platform technology is being applied in the collaboration activities in exchange for an upfront payment of $50.0 million. The Company has the exclusive right to license up to six protein targets, for each of which Kymera may receive up to $170.0 million in payments, including development, regulatory and commercial milestones as well as royalties on net product sales. In addition to the upfront payment, the Company purchased $20.0 million of Kymera's preferred stock. The Company determined that the fair value of its investment in Kymera's preferred stock, which did not have a readily determinable fair value, approximated $20.0 million. The preferred stock converted to common stock when Kymera became a publicly traded company in 2020.

The Company determined that substantially all of the fair value of the Kymera collaboration agreement was attributable to in-process research and development and no substantive processes were acquired that would constitute a business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development and recorded the $50.0 million upfront payment to “Research and development expenses” in 2019.

## Moderna, Inc.

In 2016, the Company entered into a strategic collaboration and licensing agreement with Moderna, Inc. (“Moderna”), pursuant to which the parties are seeking to identify and develop messenger ribonucleic acid (“mRNA”) therapeutics for the treatment of CF.

In September 2020, the Company entered into a new strategic collaboration and licensing agreement with Moderna (the "2020 Moderna Agreement") aimed at the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies to lung cells for the treatment of CF. Pursuant to the 2020 Moderna Agreement, Moderna received an upfront payment of $75.0 million and is eligible to receive up to $380.0 million in development, regulatory and commercial milestones as well as royalties on net product sales. The Company determined that substantially all of the fair value of the 2020 Moderna Agreement was attributable to in-process research and development and no substantive processes were acquired that would constitute a business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development and recorded the upfront payment to "Research and development expenses" in the third quarter of 2020.

## Other In-License Agreements

In addition to the collaborative arrangements described above, the Company has entered into additional in-license agreements that it does not consider to be individually significant to its consolidated financial statements. In addition to the payments described above, the Company recorded upfront, option and milestone payments totaling $84.6 million in 2020, $63.3 million in 2019 and $46.9 million in 2018 to “Research and development expenses” which included a $40.0 million upfront payment to Skyhawk Therapeutics, Inc. (“Skyhawk”) in 2020.

For Skyhawk and several other in-license agreements that are not individually significant to the Company’s consolidated financial statements, the Company determined that substantially all of the fair value of each individual agreement was attributable to in-process research and development and no substantive processes were acquired that would constitute a business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development associated with the agreements and recorded the related portion of the upfront payments to “Research and development expenses.” Please refer to Note D, “Fair Value Measurements,” and Note E, “Marketable Securities and Equity Investments,” for further information regarding the Company’s investments in its collaborators.

## Variable Interest Entities (VIEs)

The Company licensed rights to certain drug candidates from these third-party collaborators, which has resulted in the consolidation of the third-parties' financial statements into the Company's consolidated financial statements as VIEs for



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

certain periods of time. Most recently, the Company deconsolidated the financial statements of BioAxone from its consolidated financial statements as of December 31, 2018. The Company has not consolidated a VIE into its financial statements since December 31, 2018.

## BioAxone Biosciences, Inc.

In 2014, the Company entered into a license and collaboration agreement (the “BioAxone Agreement”) with BioAxone, which resulted in the consolidation of BioAxone as a VIE.

In October 2018, the Company announced it would stop clinical development of VX-210 and terminate the Phase 2b clinical trial of VX-210 based on the recommendation of the clinical trial’s Data Safety Monitoring Board and the Company’s review of interim data. In December 2018, the Company notified BioAxone of its intent to terminate the BioAxone Agreement and executed a release that immediately allowed BioAxone to control development of its neurological programs other than VX-210 without the Company’s consent. As a result of this decision, the Company recorded a $29.0 million impairment charge related to VX-210 that was attributable to noncontrolling interest.

As a result, the Company deconsolidated BioAxone as of December 31, 2018 because it determined that it no longer was the primary beneficiary of BioAxone as it no longer had the power to direct the significant activities of BioAxone. The net impact of the deconsolidation was not material to the Company’s consolidated statement of operations. The Company’s net loss attributable to noncontrolling interest for the year ended December 31, 2018 was $9.8 million.

## Out-license Agreements

The Company has entered into licensing agreements pursuant to which it has out-licensed rights to certain drug candidates to third-party collaborators. Pursuant to these out-license agreements, the Company’s collaborators become responsible for all costs related to the continued development of such drug candidates and obtain development and commercialization rights to these drug candidates. Depending on the terms of the agreements, the Company’s collaborators may be required to make upfront payments, milestone payments upon the achievement of certain product research and development objectives and may also be required to pay royalties on future sales, if any, of commercial products resulting from the collaboration. The termination provisions associated with these collaborations are generally the same as those described above related to the Company’s in-license agreements.

## Merck KGaA, Darmstadt, Germany

In January 2017, the Company entered into a strategic collaboration and license agreement (the “Oncology Agreement”) with Merck KGaA, Darmstadt, Germany (the “Licensee”). Pursuant to the Oncology Agreement, the Company granted the Licensee an exclusive worldwide license to research, develop and commercialize four oncology research and development programs including two clinical-stage programs targeting DNA damage repair: its ataxia telangiectasia and Rad3-related protein kinase inhibitor program, or ATR program, including VX-970 and VX-803, and its DNA-dependent protein kinase inhibitor program, or DNA-PK program, including VX-984. In addition, the Company granted the Licensee exclusive, worldwide rights to two pre-clinical programs.

The Oncology Agreement provided for an upfront payment from the Licensee to the Company of $230.0 million, which was recorded as “Collaborative and royalty revenues,” under the multiple element arrangement accounting guidance that was applicable in 2017. All of the Company’s activities related to the Oncology Agreement were substantially complete as of December 31, 2017.

In December 2018, the Company entered into an agreement with Merck KGaA, Darmstadt, Germany (the "DNA-PK Agreement") whereby the Company licensed the two lead Vertex DNA-PK compounds from its DNA-PK program for use in the field of gene integration for six specific indications. In exchange for this exclusive worldwide license to research, develop and commercialize the DNA-PK program for the specified indications within the field of gene integration, the Company made an upfront payment of $65.0 million. Merck KGaA, Darmstadt, Germany has the potential to receive additional milestones, primarily related to approval and reimbursement in various markets, as well as royalties on net product sales.

The Company evaluated the DNA-PK Agreement and concluded it represents a modification of the Oncology Agreement pursuant to ASC 606. As of December 2018, when the Company entered into the DNA-PK Agreement, the Company had



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

completed its obligations under the Oncology Agreement, but the Oncology Agreement was an open contract pursuant to ASC 606 since the Company could receive future royalty payments from the commercialization of the licensed programs under the Oncology Agreement.

In applying ASC 606, the Company determined that the license granted under the DNA-PK Agreement is distinct from the license granted by the Company under the Oncology Agreement since the license to the two lead Vertex DNA-PK compounds is capable of being distinct as the Company is able to benefit from the license via its ability to internally develop and commercialize the two lead Vertex DNA-PK compounds in the six named indications in the field of gene-editing, and the license is not dependent on Merck KGaA, Darmstadt, Germany providing any specialized services to the Company. In addition, the license to the two lead Vertex DNA-PK compounds granted to the Company under the DNA-PK Agreement is distinct from the license granted by the Company under the Oncology Agreement as the rights conveyed in the licensed differ and both parties have the ability to commercially benefit from the licenses on their own. Furthermore, the consideration attributable to the license of the two lead Vertex DNA-PK compounds represents fair value. Therefore, the Company determined it should account for the DNA-PK Agreement as a separate agreement.

The Company determined that substantially all of the fair value of the DNA-PK Agreement was attributable to a single in-process research and development asset that did not constitute a business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development and recorded the $65.0 million payment to “Research and development expenses” in 2018 accordingly.

## Janssen Pharmaceuticals, Inc.

In 2014, the Company entered into an agreement with Janssen Pharmaceuticals, Inc. ("Janssen"). In the third quarter of 2020, Janssen exercised its right to terminate its exclusive worldwide license to develop and commercialize certain drug candidates for the treatment of influenza, based on Phase 3 clinical trial results for pimodivir.

## Cystic Fibrosis Foundation

The Company has a research, development and commercialization agreement that was originally entered into in 2004 with the Cystic Fibrosis Foundation, as successor in interest to the Cystic Fibrosis Foundation Therapeutics, Inc. This agreement was most recently amended in 2016. Pursuant to the agreement, as amended, the Company agreed to pay royalties ranging from low-single digits to mid-single digits on potential sales of certain compounds first synthesized and/or tested between March 1, 2014 and August 31, 2016, including exelacaftor, and tiered royalties ranging from single digits to sub-teens on covered compounds first synthesized and/or tested during a research term on or before February 28, 2014, including KALYDECO (ivacaftor), ORKAMBI (lumacaftor in combination with ivacaftor) and SYMDEKO/SYMKEVI (tezacaftor in combination with ivacaftor). For combination products, such as ORKAMBI, SYMDEKO/SYMKEVI and TRIKAFTA/KAFTRIO (exelacaftor/tezacaftor/ivacaftor and ivacaftor), sales are allocated equally to each of the active pharmaceutical ingredients in the combination product.

## C. Earnings Per Share

Basic net income per share attributable to Vertex common shareholders is based upon the weighted-average number of common shares outstanding during the period. Diluted net income per share attributable to Vertex common shareholders utilizing the treasury-stock method is based upon the weighted-average number of common shares outstanding during the period plus additional weighted-average common equivalent shares outstanding during the period when the effect is dilutive.



## VERTEX PHARMACEUTICALS INCORPORATED

## Notes to Consolidated Financial Statements (Continued)

The following table sets forth the computation of basic and diluted net income per share for the periods ended:

<table><tr><td></td><td>2020</td><td>2019</td><td>2018</td></tr><tr><td></td><td colspan="3">(in thousands, except per share amounts)</td></tr><tr><td>Basic net income attributable to Vertex per common share calculation:</td><td></td><td></td><td></td></tr><tr><td>Net income attributable to Vertex common shareholders</td><td></td><td></td><td></td></tr><tr><td>Less: Undistributed earnings allocated to participating securities</td><td>$ 2,711,647</td><td>$ 1,176,810</td><td>$ 2,096,896</td></tr><tr><td>Net income attributable to Vertex common shareholders—basic</td><td>—</td><td>—</td><td>(501)</td></tr><tr><td></td><td>$ 2,711,647</td><td>$ 1,176,810</td><td>$ 2,096,395</td></tr><tr><td>Basic weighted-average common shares outstanding</td><td></td><td></td><td></td></tr><tr><td>Basic net income attributable to Vertex per common share</td><td>259,841</td><td>256,728</td><td>254,292</td></tr><tr><td></td><td>$ 10.44</td><td>$ 4.58</td><td>$ 8.24</td></tr><tr><td>Diluted net income attributable to Vertex per common share calculation:</td><td></td><td></td><td></td></tr><tr><td>Net income attributable to Vertex common shareholders</td><td></td><td></td><td></td></tr><tr><td>Less: Undistributed earnings allocated to participating securities</td><td>$ 2,711,647</td><td>$ 1,176,810</td><td>$ 2,096,896</td></tr><tr><td>Net income attributable to Vertex common shareholders—diluted</td><td>—</td><td>—</td><td>(492)</td></tr><tr><td></td><td>$ 2,711,647</td><td>$ 1,176,810</td><td>$ 2,096,404</td></tr><tr><td>Weighted-average shares used to compute basic net income per common share</td><td>259,841</td><td>256,728</td><td>254,292</td></tr><tr><td>Effect of potentially dilutive securities:</td><td></td><td></td><td></td></tr><tr><td>Stock options</td><td>1,801</td><td>2,231</td><td>2,913</td></tr><tr><td>Restricted stock units (including PSUs) and restricted stock</td><td>1,741</td><td>1,700</td><td>1,963</td></tr><tr><td>Employee stock purchase program</td><td>13</td><td>14</td><td>17</td></tr><tr><td>Weighted-average shares used to compute diluted net income per common share</td><td>263,396</td><td>260,673</td><td>259,185</td></tr><tr><td>Diluted net income attributable to Vertex per common share</td><td>$ 10.29</td><td>$ 4.51</td><td>$ 8.09</td></tr></table>

The Company did not include the securities in the following table in the computation of the net income per share attributable to Vertex common shareholders calculations because the effect would have been anti-dilutive during each period.

## D. Fair Value Measurements

The fair value of the Company’s financial assets and liabilities reflects the Company’s estimate of amounts that it would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from sources independent from the Company) and to minimize the use of unobservable inputs (the Company’s assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to determine the fair value of the Company’s financial assets and liabilities:

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs based on the Company’s assessment of the assumptions that market participants would use in pricing the asset or liability.



# VERTEX PHARMACEUTICALS INCORPORATED

## Notes to Consolidated Financial Statements (Continued)

The Company’s investment strategy is focused on capital preservation. The Company invests in instruments that meet the credit quality standards outlined in the Company’s investment policy. This policy also limits the amount of credit exposure to any one issue or type of instrument. The Company maintains strategic investments separately from the investment policy that governs its other cash, cash equivalents and marketable securities as described in Note E, “Marketable Securities and Equity Investments.” Additionally, the Company utilizes foreign currency forward contracts intended to mitigate the effect of changes in foreign exchange rates on its consolidated statement of operations.

During the three years ended December 31, 2020, the Company did not record any other-than-temporary impairment charges related to its financial assets.

The following tables set forth the Company’s financial assets and liabilities subject to fair value measurements by level within the fair value hierarchy (and does not include $2.8 billion and $2.3 billion of cash as of December 31, 2020 and 2019, respectively):

## Fair Value of Corporate Equity Securities

The Company maintains strategic investments in corporate equity securities separately from the investment policy that governs its other cash, cash equivalents and marketable securities. The Company classifies its investments in publicly traded companies as “Marketable securities” on its consolidated balance sheets. Generally, the Company’s investments in the common stock of these publicly traded companies are valued based on Level 1 inputs because they have readily determinable fair values. However, certain of the Company’s investments in publicly traded companies have been or continue to be valued based on Level 2 inputs due to transfer restrictions associated with these investments. During the year ended December 31, 2020, the Company transferred the fair value of one of its strategic investments in a publicly traded company from Level 2 to



# VERTEX PHARMACEUTICALS INCORPORATED

## Notes to Consolidated Financial Statements (Continued)

Level 1 upon the expiration of transfer restrictions associated with this investment. Please refer to Note E, “Marketable Securities and Equity Investments,” for further information on these investments.

## Fair Value of Contingent Consideration

In 2019, the Company acquired Exonics Therapeutics, Inc. (“Exonics”), a privately-held company focused on creating transformative gene-editing therapies to repair mutations that cause DMD and other severe neuromuscular diseases, including DM1. The Company’s Level 3 contingent consideration liabilities are related to $678.3 million of development and regulatory milestones potentially payable to Exonics’ former equity holders. The Company bases its estimates of the probability of achieving the milestones relevant to the fair value of contingent payments on industry data attributable to rare diseases. The discount rates used in the valuation model for contingent payments, which were between 0.4% and 1.9% as of December 31, 2020, represent a measure of credit risk and market risk associated with settling the liabilities. Significant judgment is used in determining the appropriateness of these assumptions at each reporting period. Due to the uncertainties associated with development and commercialization of drug candidates in the pharmaceutical industry and the effects of changes in other assumptions including discount rates, the Company expects its estimates regarding the fair value of contingent consideration to change in the future, resulting in adjustments to the fair value of the Company’s contingent consideration liabilities, and the effect of any such adjustments could be material.

The following table represents a rollforward of the fair value of the Company’s contingent consideration liabilities:

<table><tr><td rowspan="2"></td><td colspan="2">Year Ended December 31, 2020</td></tr><tr><td colspan="2">(in thousands)</td></tr><tr><td>Balance at December 31, 2019</td><td>$ 176,500</td><td></td></tr><tr><td>Increase in fair value of contingent payments</td><td>13,100</td><td></td></tr><tr><td>Balance at December 31, 2020</td><td>$ 189,600</td><td></td></tr></table>

The “Increase in fair value of contingent payments” in the table above was primarily due to changes in market interest rates.

## G. Hedging

Foreign currency forward contracts - Designated as hedging instruments

The Company maintains a hedging program intended to mitigate the effect of changes in foreign exchange rates for a portion of the Company’s forecasted product revenues denominated in certain foreign currencies. The program includes foreign currency forward contracts that are designated as cash flow hedges under GAAP having contractual durations from one to eighteen months. The Company recognizes realized gains and losses for the effective portion of such contracts in “Product revenues, net” in its consolidated statements of operations in the same period that it recognizes the product revenues that were impacted by the hedged foreign exchange rate changes.

The Company formally documents the relationship between foreign currency forward contracts (hedging instruments) and forecasted product revenues (hedged items), as well as the Company’s risk management objective and strategy for undertaking various hedging activities, which includes matching all foreign currency forward contracts that are designated as cash flow hedges to forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the foreign currency forward contracts are highly effective in offsetting changes in cash flows of hedged items on a prospective and retrospective basis. If the Company were to determine that a (i) foreign currency forward contract is not highly effective as a cash flow hedge, (ii) foreign currency forward contract has ceased to be a highly effective hedge or (iii) forecasted transaction is no longer probable of occurring, the Company would discontinue hedge accounting treatment prospectively. The Company measures effectiveness based on the change in fair value of the forward contracts and the fair value of the hypothetical foreign currency forward contracts with terms that match the critical terms of the risk being hedged. As of December 31, 2020, all hedges were determined to be highly effective.



# VERTEX PHARMACEUTICALS INCORPORATED

## Notes to Consolidated Financial Statements (Continued)

Prior to the adoption of ASU 2017-12 on January 1, 2019, the Company did not record any ineffectiveness related to its foreign currency forward contracts that were designated as hedging instruments in the year ended December 31, 2018. ASU 2017-12 eliminated the requirement to separately measure and report hedge ineffectiveness.

The Company considers the impact of its counterparties' credit risk on the fair value of the foreign currency forward contracts. As of December 31, 2020 and December 31, 2019, credit risk did not change the fair value of the Company's foreign currency forward contracts.

The following table summarizes the notional amount in U.S. dollars of the Company’s outstanding foreign currency forward contracts designated as cash flow hedges under U.S. GAAP:

<table><tr><td rowspan="2">Foreign Currency</td><td colspan="3">As of December 31,</td></tr><tr><td>2020</td><td>2019</td><td></td></tr><tr><td>Euro</td><td></td><td>(in thousands)</td><td></td></tr><tr><td></td><td>$</td><td>745,099</td><td>$</td></tr><tr><td>British pound sterling</td><td></td><td>160,427</td><td>87,032</td></tr><tr><td>Australian dollar</td><td></td><td>99,922</td><td>89,705</td></tr><tr><td>Canadian dollar</td><td></td><td>86,468</td><td>50,452</td></tr><tr><td>Total foreign currency forward contracts</td><td>$</td><td>1,091,916</td><td>$</td></tr></table>

The Company also enters into foreign currency forward contracts with contractual maturities of less than one month that are designed to mitigate the effect of changes in foreign exchange rates on monetary assets and liabilities, including intercompany balances. These contracts are not designated as hedging instruments under U.S. GAAP. The Company recognizes realized gains and losses for such contracts in “Other income (expense), net” in its consolidated statements of operations each period. As of December 31, 2020, the notional amount of the Company’s outstanding foreign currency forward contracts where hedge accounting under U.S. GAAP is not applied was $198.9 million.

## L. Leases

## Finance Leases

The Company’s finance lease assets and liabilities primarily relate to its corporate headquarters in Boston and research site in San Diego (the “Buildings”).

## Stock and Option Plans

The purpose of each of the Company’s stock and option plans is to attract, retain and motivate its employees, consultants and directors. Awards granted under these plans can be nonstatutory stock options (“NSOs”), incentive stock options (“ISOs”), restricted stock units (“RSUs”) including performance-based RSUs (“PSUs”), restricted stock (“RSS”), or other equity-based awards, as specified in the individual plans.

Shares issued under all of the Company’s plans are funded through the issuance of new shares. The following table contains information about the Company’s equity plans:

<table><tr><td rowspan="2">Title of Plan</td><td rowspan="2">Group Eligible</td><td rowspan="2">Type of Award Granted</td><td colspan="2">As of December 31, 2020</td></tr><tr><td>Awards Outstanding</td><td>Additional Awards Authorized for Grant</td></tr><tr><td>2013 Stock and Option Plan</td><td>Employees, Non-employee Directors and Consultants</td><td>NSO, RS, RSU and PSU</td><td>7,231,859</td><td>13,385,321</td></tr><tr><td>2006 Stock and Option Plan</td><td>Employees, Non-employee Directors and Consultants</td><td>NSO, RS and RSU</td><td>383,818</td><td>—</td></tr><tr><td></td><td></td><td>Total</td><td>7,615,677</td><td>13,385,321</td></tr></table>

All options granted under the Company’s 2013 Stock and Option Plan (“2013 Plan”) and 2006 Stock and Option Plan (“2006 Plan”) were granted with an exercise price equal to the fair value of the underlying common stock on the date of grant. As of December 31, 2020, the stock and option plan under which the Company is authorized to make new equity awards is the Company’s 2013 Plan. Under the 2013 Plan, no stock options can be awarded with an exercise price less than the fair market value on the date of grant. In 2019 and 2018, the Company’s shareholders approved increases in the number of shares authorized for issuance pursuant to the 2013 Stock and Option Plan of (i) 5,000,000 shares in 2019 and (ii) 8,000,000 shares in 2018.

During the three years ended December 31, 2020, grants to current employees and directors primarily had a grant date that was the same as the date the award was approved by the Company’s Board of Directors. During the three years ended December 31, 2020, for grants to new employees and directors, the date of grant for awards was the employee’s first day of employment or the date the director was elected to the Company’s Board of Directors. All options awarded under the Company’s stock and option plans expire not more than 10 years from the grant date.

## Stock Options

The following table summarizes information related to the outstanding and exercisable options during the year ended December 31, 2020:

<table><tr><td rowspan="2"></td><td rowspan="2">Stock Options</td><td colspan="2">Weighted-average Exercise Price</td><td rowspan="2">Weighted-average Remaining Contractual Life</td><td rowspan="2">Aggregate Intrinsic Value</td></tr><tr><td>(in thousands)</td><td>(per share)</td></tr><tr><td>Outstanding at December 31, 2019</td><td>6,272</td><td>$ 134.92</td><td></td><td></td><td></td></tr><tr><td>Granted</td><td>23</td><td>$ 286.27</td><td></td><td></td><td></td></tr><tr><td>Exercised</td><td>(1,883)</td><td>$ 121.42</td><td></td><td></td><td></td></tr><tr><td>Forfeited</td><td>(174)</td><td>$ 165.39</td><td></td><td></td><td></td></tr><tr><td>Expired</td><td>—</td><td>$ —</td><td></td><td></td><td></td></tr><tr><td>Outstanding at December 31, 2020</td><td>4,238</td><td>$ 140.47</td><td>6.34</td><td>$ 397,211</td><td></td></tr><tr><td>Exercisable at December 31, 2020</td><td>2,894</td><td>$ 125.83</td><td>5.73</td><td>$ 313,936</td><td></td></tr></table>

The aggregate intrinsic value in the table above represents the total pre-tax amount, net of exercise price, that would have been received by option holders if all option holders had exercised all options with an exercise price lower than the market price on the last business day of 2020, which was $233.91 based on the average of the high and low price of the Company’s common stock on that date.

The total intrinsic value (the amount by which the fair market value exceeded the exercise price) of stock options exercised during 2020, 2019 and 2018 was $255.0 million, $325.9 million and $258.2 million, respectively. The total cash received by the Company as a result of employee stock option exercises during 2020, 2019 and 2018 was $228.2 million, $317.8 million and $263.4 million, respectively.

## Restricted Stock Units (excluding PSUs) and Restricted Stock

The following table summarizes the restricted stock unit and restricted stock activity of the Company during the year ended December 31, 2020:

<table><tr><td rowspan="3"></td><td colspan="3">Restricted Stock Units (excluding PSUs)</td><td colspan="3">Restricted Stock</td></tr><tr><td colspan="2">Weighted-average Grant-date Fair Value</td><td rowspan="2">Number of Units</td><td colspan="2">Weighted-average Grant-date Fair Value</td><td></td></tr><tr><td>Number of Shares</td><td>(per share)</td><td>(in thousands)</td><td>(per share)</td><td></td></tr><tr><td>Unvested at December 31, 2019</td><td>3,131</td><td>$     163.61</td><td>92</td><td>$     91.97</td><td></td><td></td></tr><tr><td>Granted</td><td>1,244</td><td>$     258.45</td><td>—</td><td>$      —</td><td></td><td></td></tr><tr><td>Vested</td><td>(1,443)</td><td>$     159.10</td><td>(92)</td><td>$     91.97</td><td></td><td></td></tr><tr><td>Cancelled</td><td>(210)</td><td>$     193.84</td><td>—</td><td>$      —</td><td></td><td></td></tr><tr><td>Unvested at December 31, 2020</td><td>2,722</td><td>$     206.99</td><td>—</td><td>$      —</td><td></td><td></td></tr></table>

The total fair value of restricted stock units that vested during 2020, 2019 and 2018 (measured on the date of vesting) was $370.3 million, $178.2 million and $104.8 million, respectively. The total fair value of restricted stock that vested during 2020, 2019 and 2018 (measured on the date of vesting) was $21.4 million, $70.7 million and $114.5 million, respectively.

## Performance-based RSUs (PSUs)

The potential range of shares issuable pursuant to the Company’s PSU awards range from 0% to 200% of the target shares based on financial and non-financial measures. Fifty percent of PSUs that could be earned have a one-year performance period with the amount actually earned dependent upon the Company’s financial performance and with vesting of the earned shares in three equal installments over a three-year period. The remaining 50% of PSUs that could be earned have a three-year performance period with the amount actually earned dependent upon the achievement of multiple clinical development milestones and with the earned shares cliff vesting at the end of the three-year performance period.

The following table summarizes the PSU activity of the Company during the year ended December 31, 2020:

<table><tr><td rowspan="3"></td><td colspan="3">Performance-Based RSU</td></tr><tr><td colspan="2">Number of Units</td><td>Weighted-average Grant-date Fair Value</td></tr><tr><td>(in thousands)</td><td></td><td>(per share)</td></tr><tr><td>Unvested at December 31, 2019 (1)</td><td>734</td><td>$</td><td>143.21</td></tr><tr><td>Granted (2)</td><td>547</td><td>$</td><td>241.38</td></tr><tr><td>Vested</td><td>(577)</td><td>$</td><td>114.11</td></tr><tr><td>Cancelled</td><td>(48)</td><td>$</td><td>194.46</td></tr><tr><td>Unvested at December 31, 2020</td><td>656</td><td>$</td><td>202.06</td></tr></table>

(1) “Unvested” represents the Company’s PSUs at target to the extent performance has not been certified plus the actual number of shares that continue to be subject to service conditions for which the performance has been achieved and certified.

(2) “Granted” represents (i) the target number of shares issuable for grants during 2020 and (ii) any change in the number of shares issuable pursuant to outstanding PSUs based on performance certification during 2020.

The total fair value of PSUs that vested during 2020, 2019 and 2018 (measured on the date of vesting) was $138.5 million, $73.3 million and $23.2 million, respectively.

## Employee Stock Purchase Plan

The Company has an employee stock purchase plan (the “ESPP”). The ESPP permits eligible employees to enroll in a twelve-month offering period comprising two six-month purchase periods. Participants may purchase shares of the Company’s common stock, through payroll deductions, at a price equal to 85% of the fair market value of the common stock on the first day of the applicable twelve-month offering period, or the last day of the applicable six-month purchase period,



# VERTEX PHARMACEUTICALS INCORPORATED

## Notes to Consolidated Financial Statements (Continued)

whichever is lower. Purchase dates under the ESPP occur on or about May 14 and November 14 of each year. As of December 31, 2020, there were 1,996,321 shares of common stock authorized for issuance pursuant to the ESPP.

In 2020, the following shares were issued to employees under the ESPP:

<table><tr><td rowspan="2"></td><td colspan="2">Year Ended December 31, 2020</td></tr><tr><td>(in thousands, except per share amount)</td><td></td></tr><tr><td>Number of shares</td><td></td><td>203,055</td></tr><tr><td>Average price paid per share</td><td>$</td><td>167.93</td></tr></table>

## Employee Benefits

The Company has a 401(k) retirement plan (the “Vertex 401(k) Plan”) in which substantially all of its permanent U.S. employees are eligible to participate. Participants may contribute up to 60% of their annual compensation to the Vertex 401(k) Plan, subject to statutory limitations. The Company may declare discretionary matching contributions to the Vertex 401(k) Plan. The Company pays matching contributions in the form of cash. For the years ended December 31, 2020, 2019 and 2018, the Company contributed approximately $19.2 million, $15.8 million and $13.9 million to the plan, respectively.

## N. Stock-based Compensation Expense

The Company recognizes share-based payments to employees as compensation expense using the fair value method. The fair value of stock options and shares purchased pursuant to the ESPP is calculated using the Black-Scholes option pricing model. The fair value of restricted stock units, including PSUs, and restricted stock is based on the intrinsic value on the date of grant. Stock-based compensation, measured at the grant date based on the fair value of the award, is typically recognized as expense ratably over the requisite service period.

The effect of stock-based compensation expense during the three years ended December 31, 2020 was as follows:

<table><tr><td rowspan="2"></td><td>2020</td><td colspan="2">2019</td><td>2018</td></tr><tr><td colspan="4">(in thousands)</td></tr><tr><td>Stock-based compensation expense by line item:</td><td></td><td></td><td></td><td></td></tr><tr><td>Cost of sales</td><td>$     5,579</td><td>$     5,575</td><td>$     4,543</td><td></td></tr><tr><td>Research and development expenses</td><td>262,690</td><td>224,558</td><td>203,112</td><td></td></tr><tr><td>Sales, general and administrative expenses</td><td>161,192</td><td>130,356</td><td>117,392</td><td></td></tr><tr><td>Total stock-based compensation expense included in costs and expenses</td><td>429,461</td><td>360,489</td><td>325,047</td><td></td></tr><tr><td>Income tax effect</td><td>(146,959)</td><td>(124,225)</td><td>—</td><td></td></tr><tr><td>Total stock-based compensation included in costs and expenses, net of tax</td><td>$     282,502</td><td>$     236,264</td><td>$     325,047</td><td></td></tr></table>

The Company maintained a valuation allowance on the majority of its NOLs and other deferred tax assets until December 31, 2018. Therefore, there was no “Income tax effect” of stock-based compensation expense for the year ended December 31, 2018.

The stock-based compensation expense by type of award during the three years ended December 31, 2020 was as follows:

<table><tr><td rowspan="2"></td><td>2020</td><td colspan="2">2019</td><td>2018</td></tr><tr><td colspan="4">(in thousands)</td></tr><tr><td>Stock-based compensation expense by type of award:</td><td></td><td></td><td></td><td></td></tr><tr><td>Restricted stock units (including PSUs) and restricted stock</td><td>$     360,364</td><td>$     254,276</td><td>$     207,845</td><td></td></tr><tr><td>Stock options</td><td>59,722</td><td>96,737</td><td>107,854</td><td></td></tr><tr><td>ESPP share issuances</td><td>12,984</td><td>11,196</td><td>9,933</td><td></td></tr><tr><td>Stock-based compensation expense related to inventories</td><td>(3,609)</td><td>(1,720)</td><td>(585)</td><td></td></tr><tr><td>Total stock-based compensation expense included in costs and expenses</td><td>$     429,461</td><td>$     360,489</td><td>$     325,047</td><td></td></tr></table>

The Company capitalizes stock-based compensation expense to inventories, all of which is attributable to employees who support the Company’s manufacturing operations for the Company’s products.

The following table sets forth the Company’s unrecognized stock-based compensation expense as of December 31, 2020, by type of award and the weighted-average period over which that expense is expected to be recognized:

## Stock Options

In each of the three years ended December 31, 2020, the Company issued stock options to its non-employee directors. In 2019 and 2018, the Company issued stock options with service conditions, which were generally the vesting periods of the awards, to its employees. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock options at the grant date. The Black-Scholes option pricing model uses the option exercise price as well as estimates and assumptions related to the expected price volatility of the Company's stock, the rate of return on risk-free investments, the expected period during which the options will be outstanding, and the expected dividend yield for the Company's stock to estimate the fair value of a stock option on the grant date. The options granted during 2020, 2019 and 2018 had a weighted-average grant-date fair value per share of $88.37, $61.32 and $60.83, respectively.

The fair value of each option granted during 2020, 2019 and 2018 was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

<table><tr><td>Stock options granted</td><td>2020</td><td>2019</td><td>2018</td></tr><tr><td>Expected stock price volatility</td><td>22,636</td><td>1,520,743</td><td>2,297,328</td></tr><tr><td>Risk-free interest rate</td><td>35.87%</td><td>36.99%</td><td>40.50%</td></tr><tr><td>Expected term of options (in years)</td><td>0.43%</td><td>2.32%</td><td>2.61%</td></tr><tr><td>Expected annual dividends</td><td>4.67</td><td>4.27</td><td>4.55</td></tr></table>

The weighted-average valuation assumptions were determined as follows:

- Expected stock price volatility: Expected stock price volatility is calculated using the trailing one-month average of daily implied volatilities prior to the grant date. Implied volatility is based on options to purchase the Company’s stock with remaining terms of greater than one year that are regularly traded in the market.

- Risk-free interest rate: The Company bases the risk-free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected option term.

- Expected term of options: The expected term of options represents the period of time options are expected to be outstanding. The Company uses historical data to estimate employee exercise and post-vest termination behavior. The Company believes that all groups of employees exhibit similar exercise and post-vest termination behavior and therefore does not stratify employees into multiple groups in determining the expected term of options.

- Expected annual dividends: The estimate for annual dividends is $0.00 because the Company has not historically paid, and does not intend for the foreseeable future to pay, a dividend.

The Company awards restricted stock units with service conditions, which are generally the vesting periods of the awards. As of December 31, 2020, the Company did not have any unvested restricted stock awards remaining, which it awarded until 2016.

The Company grants PSUs to certain members of senior management. Half of the PSUs contain financial goals as the performance metric and the other half contain non-financial goals. A target number of shares is established for each award, however the actual number of shares that are issued when an award vests may range from zero to 200% of the target amount depending upon the level of achievement of the applicable performance metric. The financial-based PSUs vest in three equal installments over a three-year period and are expensed ratably over that same period based upon an assessment of the likely level of achievement. The non-financial based PSUs cliff vest at the end of the three-year performance period and are expensed on a straight-line basis over that same period based upon an assessment of the likely level of achievement.

## Employee Stock Purchase Plan

The weighted-average fair value of each purchase right granted during 2020, 2019 and 2018 was $65.88, $47.79 and $44.04, respectively. The following table reflects the weighted-average assumptions used in the Black-Scholes option pricing model for 2020, 2019 and 2018:

<table><tr><td></td><td>2020</td><td>2019</td><td>2018</td></tr><tr><td>Expected stock price volatility</td><td>37.70%</td><td>33.43%</td><td>36.51%</td></tr><tr><td>Risk-free interest rate</td><td>0.11%</td><td>2.08%</td><td>2.36%</td></tr><tr><td>Expected term (in years)</td><td>0.71</td><td>0.74</td><td>0.75</td></tr><tr><td>Expected annual dividends</td><td>—</td><td>—</td><td>—</td></tr></table>

The expected stock price volatility for ESPP offerings is based on implied volatility. The Company bases the risk-free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected term. The expected term represents purchases and purchase periods that take place within the offering period. The expected annual dividends estimate is $0.00 because the Company has not historically paid, and does not for the foreseeable future intend to pay, a dividend.

The Company is subject to U.S. federal, state, and foreign income taxes. The Company’s provision for income taxes during the years ended December 31, 2020 and 2019, has increased compared to historical amounts due to the release of the Company’s valuation allowance on the majority of its net operating losses (“NOLs”) and other deferred tax assets as of December 31, 2018. Starting in 2019, the Company began recording a provision for income taxes approximating the statutory rates on its pre-tax income. The Company’s effective tax rate of 13% for 2020 was lower than the U.S. statutory rate primarily due to (i) discrete tax benefits associated with an intra-entity transfer of intellectual property rights to the United Kingdom (“U.K.”), the write-off of a long-term intercompany receivable, and an increase in the U.K.’s corporate tax rate; and (ii) excess tax benefits related to stock-based compensation. The impact of these items was partially offset by a U.S. deemed dividend. The Company’s effective tax rate of 16% for 2019 was lower than the U.S. statutory rate primarily due to excess tax benefits related to stock-based compensation and research and development tax credits. The Company utilized substantially all of its remaining previously benefited U.S. NOLs in 2020. As a result, a larger portion of the Company’s tax provision will represent a cash tax payable in future periods.



# VERTEX PHARMACEUTICALS INCORPORATED

## Notes to Consolidated Financial Statements (Continued)

In the second quarter of 2020, the Company completed an intra-entity transfer of intellectual property rights to the U.K., resulting in a deferred tax benefit of $209.0 million. The Company expects to be able to utilize the deferred tax asset resulting from the intra-entity transfer.

In 2018, the change in the “Benefit from income taxes attributable to valuation allowances” was primarily related to the release of the Company’s valuation allowances on the majority of its NOLs and other deferred tax assets related to the U.S. and the U.K. The Company released these valuation allowances after determining it was more likely than not that its deferred tax assets would be realized in the future based on positive evidence, including significant cumulative consolidated and U.S. income over the three years ended December 31, 2018, revenue growth, clinical trial data from the Company’s triple combination regimens, competitor clinical progress and expectations regarding future profitability, and negative evidence, including the potential impact of competition on the Company’s projections and cumulative losses in one of the jurisdictions.

Deferred tax assets and liabilities are determined based on the difference between financial statement and tax bases using enacted tax rates in effect for the year in which the differences are expected to reverse. The components of the deferred taxes were as follows:

<table><tr><td rowspan="3"></td><td colspan="3">As of December 31,</td></tr><tr><td colspan="2">2020</td><td>2019</td></tr><tr><td colspan="3">(in thousands)</td></tr><tr><td>Deferred tax assets:</td><td></td><td></td><td></td></tr><tr><td>Net operating loss</td><td>$     140,563</td><td>$     512,256</td><td></td></tr><tr><td>Tax credit carryforwards</td><td>406,120</td><td>549,543</td><td></td></tr><tr><td>Intangible assets</td><td>507,484</td><td>275,290</td><td></td></tr><tr><td>Deferred revenues</td><td>20,962</td><td>18,833</td><td></td></tr><tr><td>Stock-based compensation</td><td>89,203</td><td>85,199</td><td></td></tr><tr><td>Accrued expenses</td><td>47,326</td><td>44,367</td><td></td></tr><tr><td>Finance lease liabilities</td><td>118,749</td><td>119,160</td><td></td></tr><tr><td>Operating lease assets</td><td>65,046</td><td>13,114</td><td></td></tr><tr><td>Other</td><td>987</td><td>8,596</td><td></td></tr><tr><td>Gross deferred tax assets</td><td>1,396,440</td><td>1,626,358</td><td></td></tr><tr><td>Valuation allowance</td><td>(213,750)</td><td>(205,192)</td><td></td></tr><tr><td>Total deferred tax assets</td><td>1,182,690</td><td>1,421,166</td><td></td></tr><tr><td>Deferred tax liabilities:</td><td></td><td></td><td></td></tr><tr><td>Property and equipment</td><td>(116,955)</td><td>(101,235)</td><td></td></tr><tr><td>Acquired intangibles</td><td>(87,025)</td><td>(87,160)</td><td></td></tr><tr><td>Unrealized gain</td><td>(17,553)</td><td>(28,838)</td><td></td></tr><tr><td>Operating lease liabilities</td><td>(63,310)</td><td>(13,118)</td><td></td></tr><tr><td>Other</td><td>(15,068)</td><td>—</td><td></td></tr><tr><td>Net deferred tax assets</td><td>$     882,779</td><td>$     1,190,815</td><td></td></tr></table>

On a periodic basis, the Company reassesses the valuation allowance on its deferred income tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. As of December 31, 2020, the Company maintained a valuation allowance of $213.8 million related primarily to U.S. state and foreign tax attributes.

As of December 31, 2020, the Company had NOL carryforwards of $97.4 million, which are subject to annual utilization limitations, and tax credits of $249.2 million for U.S. federal income tax purposes. As of December 31, 2020, the Company had NOL carryforwards of $708.2 million and tax credits of $179.1 million for U.S. state income tax purposes. The U.S. federal NOLs may be carried forward indefinitely, with the exception of $29.1 million that will begin to expire in 2030. The state NOL carryforwards and tax credits expire at various dates through 2040 and may be used to offset future state income tax liabilities. As of December 31, 2020, the Company had foreign net operating loss carryforwards of $521.6 million, including $10.6 million that were subject to expiration at various dates through 2040 and $511.0 million that had an indefinite carryforward period.

Unrecognized tax benefits during the three years ended December 31, 2020 were as follows:

<table><tr><td></td><td colspan="2">2020</td><td colspan="2">2019</td><td colspan="2">2018</td></tr><tr><td></td><td colspan="6">(in thousands)</td></tr><tr><td>Balance at beginning of the period</td><td>$     33,920</td><td>$     19,549</td><td>$     3,814</td><td></td><td></td><td></td></tr><tr><td>Increases related to current period tax positions</td><td>26,653</td><td>14,407</td><td>9,704</td><td></td><td></td><td></td></tr><tr><td>Increases related to prior period tax positions</td><td>26,732</td><td>598</td><td>6,031</td><td></td><td></td><td></td></tr><tr><td>Decreases related to prior period tax positions</td><td>—</td><td>(156)</td><td>—</td><td></td><td></td><td></td></tr><tr><td>Settlement with tax authorities</td><td>—</td><td>(478)</td><td>—</td><td></td><td></td><td></td></tr><tr><td>Statute of limitations expiration</td><td>(657)</td><td>—</td><td>—</td><td></td><td></td><td></td></tr><tr><td>Balance at end of period</td><td>$     86,648</td><td>$     33,920</td><td>$     19,549</td><td></td><td></td><td></td></tr></table>

As of December 31, 2020, the Company has classified $48.1 million and $38.5 million of its unrecognized tax benefits as credits to “Deferred tax assets” and “Accrued expenses,” respectively, on its consolidated balance sheet.

The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by a taxing authority. Unrecognized tax benefits represent the aggregate tax effect of differences between tax return positions and the benefits recognized in the consolidated financial statements. As of December 31, 2020, 2019 and 2018, the Company had $75.8 million, $33.9 million and $19.5 million, respectively, of net unrecognized tax benefits, which would affect the Company’s tax rate if recognized. The Company does not expect that its unrecognized tax benefits will materially change within the next twelve months. The Company accrues interest and penalties related to unrecognized tax benefits as a component of its “Provision for (benefit from) income taxes.” The Company did not recognize any material interest or penalties related to uncertain tax positions during the three years ended December 31, 2020.

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act includes provisions relating to several aspects of corporate income taxes. The CARES Act did not have a significant impact on the Company’s provision for income taxes.

As of December 31, 2020, foreign earnings, which were not significant, have been retained by the Company’s foreign subsidiaries for indefinite reinvestment. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company could be subject to withholding taxes payable to the various foreign countries.

The Company files U.S. federal income tax returns and income tax returns in various state, local and foreign jurisdictions. The Company is no longer subject to any tax assessment from an income tax examination in the U.S. or any other major taxing jurisdiction for years before 2011, except where the Company has NOLs or tax credit carryforwards that originate before 2011. The Company has various income tax audits ongoing at any time throughout the world.

## P. Commitments and Contingencies

## Revolving Credit Facilities

The Company and certain of its subsidiaries have entered into two credit agreements (the “Credit Agreements”) with Bank of America, N.A., as administrative agent and the lenders referred to therein (the “Lenders”). The Credit Agreements were not drawn upon at closing and the Company has not drawn upon them to date. Amounts drawn pursuant to the Credit Agreements, if any, will be used for general corporate purposes. Any amounts borrowed under the Credit Agreements will bear interest, at the Company’s option, at either a base rate or a Eurocurrency rate, in each case plus an applicable margin based on the Company’s consolidated leverage ratio (the ratio of the Company’s total consolidated funded indebtedness to the Company’s consolidated EBITDA for the most recently completed four fiscal quarter period).

In September 2019, the Company and certain of its subsidiaries entered into a $500.0 million unsecured revolving facility (the “2019 Credit Agreement”) with the Lenders, which matures on September 17, 2024. The 2019 Credit Agreement superseded the Company’s credit agreement entered into in 2016 with Bank of America, N.A. serving in the same capacity. Under the 2019 Credit Agreement, the applicable margins on base rate loans range from 0.125% to 0.500% and the



# VERTEX PHARMACEUTICALS INCORPORATED

# Notes to Consolidated Financial Statements (Continued)

applicable margins on Eurocurrency loans range from 1.125% to 1.500%. The 2019 Credit Agreement provides a sublimit of $50.0 million for letters of credit.

In September 2020, the Company and certain of its subsidiaries entered into a $2.0 billion unsecured revolving facility (the "2020 Credit Agreement") with the Lenders, which matures on September 18, 2022. Under the 2020 Credit Agreement, the applicable margins on base rate loans range from 0.500% to 0.875% and the applicable margins on Eurocurrency loans range from 1.500% to 1.875%. The 2020 Credit Agreement does not support the issuance of letters of credit.

Subject to satisfaction of certain conditions, the Company may request that the borrowing capacity for each of the Credit Agreements be increased by an additional $500.0 million. Any amounts borrowed pursuant to the Credit Agreements are guaranteed by certain of the Company’s existing and future domestic subsidiaries, subject to certain exceptions.

The Credit Agreements contain customary representations and warranties and affirmative and negative covenants, including financial covenants to maintain (x) subject to certain limited exceptions, a consolidated leverage ratio of 3.50 to 1.00, subject to an increase to 4.00 to 1.00 following a material acquisition and (y) a consolidated interest coverage ratio of 2.50 to 1.00, in each case measured on a quarterly basis. As of December 31, 2020, the Company was in compliance with the covenants described above. The Credit Agreements also contain customary events of default. In the case of a continuing event of default, the administrative agent would be entitled to exercise various remedies, including the acceleration of amounts due under outstanding loans.

Direct costs related to the Credit Agreements, which were not material to the Company’s financial statements, were deferred and recorded over the term of the Credit Agreements.

## Guaranties and Indemnifications

As permitted under Massachusetts law, the Company’s Articles of Organization and By-laws provide that the Company will indemnify certain of its officers and directors for certain claims asserted against them in connection with their service as an officer or director. The maximum potential amount of future payments that the Company could be required to make under these indemnification provisions is unlimited. However, the Company has purchased directors’ and officers’ liability insurance policies that could reduce its monetary exposure and enable it to recover a portion of any future amounts paid. No indemnification claims currently are outstanding, and the Company believes the estimated fair value of these indemnification arrangements is minimal.

The Company customarily agrees in the ordinary course of its business to indemnification provisions in agreements with clinical trial investigators and sites in its drug development programs, sponsored research agreements with academic and not-for-profit institutions, various comparable agreements involving parties performing services for the Company, and its real estate leases. The Company also customarily agrees to certain indemnification provisions in its drug discovery, development and commercialization collaboration agreements. With respect to the Company’s clinical trials and sponsored research agreements, these indemnification provisions typically apply to any claim asserted against the investigator or the investigator’s institution relating to personal injury or property damage, violations of law or certain breaches of the Company’s contractual obligations arising out of the research or clinical testing of the Company’s compounds or drug candidates. With respect to lease agreements, the indemnification provisions typically apply to claims asserted against the landlord relating to personal injury or property damage caused by the Company, to violations of law by the Company or to certain breaches of the Company’s contractual obligations. The indemnification provisions appearing in the Company’s collaboration agreements are similar to those for the other agreements discussed above, but in addition provide some limited indemnification for its collaborator in the event of third-party claims alleging infringement of intellectual property rights. In each of the cases above, the indemnification obligation generally survives the termination of the agreement for some extended period, although the Company believes the obligation typically has the most relevance during the contract term and for a short period of time thereafter. The maximum potential amount of future payments that the Company could be required to make under these provisions is generally unlimited. The Company has purchased insurance policies covering personal injury, property damage and general liability that reduce its exposure for indemnification and would enable it in many cases to recover all or a portion of any future amounts paid. The Company has never paid any material amounts to defend lawsuits or settle claims related to these indemnification provisions. Accordingly, the Company believes the estimated fair value of these indemnification arrangements is minimal.

## Other Contingencies

The Company has certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a reserve for contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. There were no material contingent liabilities accrued as of December 31, 2020 or 2019.

Generally, only items that are deducted from the Selling Party’s gross invoiced sales price of Shared Product(s), as included in the Selling Party’s published financial statements and that are in accordance with GAAP, applied on a consistent basis, will be deducted from such gross invoiced sales price for purposes of the calculation of Net Sales. However, compulsory payments required by federal or state governments based upon sales volume or market share of Shared Products (but for clarity excluding taxes on the Selling Party’s net income), to the extent borne by the Selling Party, will be deducted from “Net Sales” regardless of its classification in the Selling Party’s published financial statements; provided that any such deduction will be limited to that share of such compulsory payment proportional to the share of the total sales volume or market share of the Selling Party used to compute the compulsory payment represented by applicable Net Sales of Shared Products.

A qualifying amount may be deducted only once regardless of the number of the preceding categories that describe such amount. If a Selling Party makes any adjustment to such deductions after the associated Net Sales have been reported pursuant to this Agreement, the adjustments will be reported with the next Summary Statement. Sales between or among a Party, its Affiliates and Sublicensees will be excluded from the computation of Net Sales if such sales are not intended for end use, but Net Sales will include the subsequent final sales to Third Parties by a Party or any such Affiliates or Sublicensees. A Shared Product will not be deemed to be sold if the Shared Product is provided free of charge to a Third Party in reasonable quantities as a sample consistent with industry standard promotional and sample practices. [***].

If a sale, transfer or other disposition with respect to Shared Products involves consideration other than cash or is not at arm’s length, then the Net Sales from such sale, transfer or other disposition will be calculated on the [***].

Solely for purposes of calculating Net Sales, if a Party or its Affiliates or any permitted Sublicensee sells a Shared Product in the form of a combination product

containing a Shared Product and one or more other therapeutically or prophylactically active ingredients or delivery devices (whether combined in a single formulation or package, as applicable, or formulated separately but packaged under a single label approved by a Regulatory Authority and sold together for a single price) (a “Combination Product”), Net Sales of such Combination Product will be calculated by multiplying actual Net Sales of such Combination Product as determined in the first paragraph of the definition of “Net Sales” by the fraction A/(A+B) where [***]. The weighted average invoice prices referenced above will be calculated with reference to the prevailing prices during the applicable Calendar Quarter in those top selling countries that equate to [***]% of Net Sales of the applicable Shared Product in the Territory, with the prices weighted in the calculation to reflect the actual relative sales value of the Shared Product in each of the countries to which the calculation relates. If it is not possible to determine the fraction A/(A+B) based on the criteria specified in the preceding sentence (e.g., if a Shared Product component is not sold separately), the Parties shall determine Net Sales for the Shared Product in such Combination Product in good faith by mutual agreement [***].

## ARTICLE 13

## INDEMNIFICATION; INSURANCE

13.1. Indemnification by Vertex. Vertex will indemnify, defend and hold harmless each CRISPR Indemnified Party from and against any and all Liability that the CRISPR Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of:



[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would cause competitive harm if publicly disclosed.

13.1.1. [***];

13.1.2. [***];

except, in each case, to the extent CRISPR is required to indemnify Vertex pursuant to Section 13.2.

13.2. Indemnification by CRISPR. Each CRISPR Entity will jointly and severally indemnify, defend and hold harmless each Vertex Indemnified Party from and against any and all Liabilities that the Vertex Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of:

13.2.1. [***];

13.2.2. [***];

except, in each case, to the extent Vertex is required to indemnify CRISPR pursuant to Section 13.1.

13.3. Procedure. Each Party will notify the other Party in writing if it becomes aware of a claim for which indemnification may be sought hereunder. In case any proceeding (including any governmental investigation) will be instituted involving any Indemnified Party, such Indemnified Party will give prompt written notice of the indemnity claim to the Indemnifying Party and provide a copy to the Indemnifying Party of any complaint, summons or other written or verbal notice that the Indemnified Party receives in connection with any such claim. An Indemnified Party’s failure to deliver written notice will relieve the Indemnifying Party of liability to the Indemnified Party under this ARTICLE 13 only to the extent such delay is prejudicial to the Indemnifying Party’s ability to defend such claim. Provided that the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party will permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by negotiated settlement or otherwise and any failure to contest prior to assuming control will be deemed to be an admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim and will not settle or otherwise resolve such claim without the Indemnified Party’s prior written consent, which will not be withheld, delayed or conditioned unreasonably, other than settlements only involving the payment of monetary awards for which the Indemnifying Party will be fully-responsible. The Indemnified Party will cooperate with the Indemnifying Party in such Party’s defense of any claim for which indemnity is sought under this Agreement, at the Indemnifying Party’s sole cost and expense.

13.4. Other Third Party Claims. If a Third Party brings a claim of any nature arising out of [***] other than [***], the [***] will [***]. [***] will [***]. The [***] will [***]. The [***]. If [***].

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would cause competitive harm if publicly disclosed.

13.5.6. Self-Insurance. Notwithstanding the foregoing, [***] may self-insure to the extent that it self-insures for its other activities.

13.6. Limitation of Consequential Damages. Except for (a) claims of a Third Party that are subject to indemnification under this ARTICLE 13, (b) claims arising out of a Party’s willful misconduct, or (c) a Party’s breach of ARTICLE 15, neither Party nor any of its Affiliates will be liable to the other Party or its Affiliates for any incidental, consequential, special, punitive or other indirect damages or lost or imputed profits or royalties, lost data or cost of procurement of substitute goods or services, whether liability is asserted in contract, tort (including negligence and strict product liability), indemnity or contribution, and irrespective of whether that Party or any representative of that Party has been advised of, or otherwise might have anticipated the possibility of, any such loss or damage.

## 14.2. Termination of the Agreement.

14.2.1. Vertex’s Termination for Convenience. Vertex will be entitled to terminate this Agreement for convenience, in its entirety or with respect to one or more Shared Product(s), by providing CRISPR 90 days’ written notice of such termination; provided, however, that if any termination under this Section 14.2.1 with respect to a Shared Product occurs after such Shared Product has received Marketing Approval, Vertex will provide CRISPR no less than 270 days’ written notice of such termination.

## 14.2.2. Termination for Material Breach.

(a) Vertex’s Right to Terminate. If CRISPR (or any CRISPR Entity(ies)) is in material breach of this Agreement, then Vertex may deliver notice of such material breach to CRISPR. If the breach is curable, CRISPR will have [***] days from the receipt of such notice to cure such breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [***] Business Days following receipt of such notice). If either CRISPR fails to cure such breach within such [***]-day or [***]-Business Day period, as



[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would cause competitive harm if publicly disclosed.

applicable, or the breach is not subject to cure, Vertex in its sole discretion may either (i) terminate this Agreement (A) if such breach relates solely to a particular Shared Product, with respect to the Shared Product affected by such breach or (B) if such breach relates to this Agreement as a whole, in its entirety, by providing written notice to CRISPR or (ii) elect to exercise the alternative remedy provisions set forth in Section 14.5 (in lieu of termination).

(b) CRISPR’s Right to Terminate. If Vertex is in material breach of this Agreement, then CRISPR may deliver notice of such material breach to Vertex. If the breach is curable, Vertex will have [***] days following receipt of such notice to cure such breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [***] Business Days following receipt of such notice). If Vertex fails to cure such breach within the [***]-day or [***]-Business Day period, as applicable, or the breach is not subject to cure, CRISPR in its sole discretion may either (i) terminate this Agreement (A) if such breach relates solely to a particular Shared Product, with respect to the Shared Product affected by such breach or (B) if such breach relates to this Agreement as a whole, in its entirety, by providing written notice to Vertex or (ii) elect to exercise the alternative remedy provisions set forth in Section 14.5 (in lieu of termination).

(c) Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in this Section 14.2.2 disputes in good faith the existence, materiality, or failure to cure of any such breach that is not a payment breach, and provides notice to the Non-Breachng Party of such dispute within the relevant cure period, the Non-Breachng Party will not have the right to terminate this Agreement in accordance with this Section 14.2.2, unless and until the relevant dispute has been resolved. It is understood and acknowledged that during the pendency of such dispute, all the terms and conditions of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder.

14.2.3. Termination for Patent Challenge. If a Party (the “Challenging Party”) (A) commences or actively and voluntarily participates in any action or proceeding (including any Patent opposition or re-examination proceeding), or otherwise asserts any claim, challenging or denying the validity or enforceability of any claim of any Patent that is licensed to the Challenging Party under this Agreement or (B) actively and voluntarily

assists any other Person in bringing or prosecuting any action or proceeding (including any Patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim of any Patent that is licensed to the Challenging Party under this Agreement by the other Party (the "Non-Challenging Party") (each of (A) and (B), a "Patent Challenge"), then, to the extent permitted by Applicable Law, the Non-Challenging Party shall have the right, in its sole discretion, to give notice to the Challenging Party that the Non-Challenging Party may terminate the license(s) granted under such Patent to the Challenging Party [***] days following such notice, and, unless the Challenging Party withdraws or causes to be withdrawn all such challenge(s), or in the case of ex-parte proceedings, multi-party proceedings, or other Patent Challenges that the Challenging Party does not have the power to unilaterally withdraw or cause to be withdrawn, the Challenging Party ceases assisting any other party to such Patent Challenge and, to the extent the Challenging Party is a party to such Patent Challenge, it withdraws from such Patent Challenge within such [***]-day period, the Non-Challenging Party shall have the right to deem the Challenging Party to have exercised an Opt-Out with respect to any Shared Product(s) Covered by a Patent that is the subject of such Patent Challenge, by providing written notice thereof to the Challenging Party, in which case the provisions of Section 14.3 shall apply; provided, however, [***]. The foregoing right of the Non-Challenging Party shall not apply with respect to any Patent Challenge where the Patent Challenge is made in defense of an assertion of the relevant Patent that is first brought by the Non-Challenging Party against the Challenging Party. For the avoidance of doubt, any participation by the Challenging Party or its employees in any claim, challenge or proceeding in response to a subpoena or as required under a pre-existing agreement between the Challenging Party's employee(s) or consultant(s) and their prior employer(s) shall not constitute active and voluntary participation or assistance and shall not give rise to the Non-Challenging Party's right to deem the Challenging Party as having exercised an Opt-Out with respect to any Shared Product hereunder.

14.2.4. Termination for Insolvency. If CRISPR (or any CRISPR Entity(ies)) undergoes any Insolvency Event, then Vertex may terminate this Agreement in its entirety effective immediately upon written notice to CRISPR. If an Insolvency Event occurs with respect to CRISPR (or any CRISPR Entity(ies)):

If (x) a case under the U.S. Bankruptcy Code is commenced by or against CRISPR (or any CRISPR Entity(ies)), (y) this Agreement is rejected as provided in the U.S. Bankruptcy Code, and (z) Vertex elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, CRISPR (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(i) provide to Vertex all such intellectual property (including all embodiments thereof) held by CRISPR and such successors and assigns, or otherwise available to them, immediately upon Vertex’s written request. Whenever CRISPR or any of its successors or assigns provides to Vertex any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 14.2.4(a)(i), Vertex will have the right to perform CRISPR’s obligations hereunder with respect to such intellectual property, but neither such provision nor such performance by Vertex will release CRISPR from liability resulting from rejection of the license or the failure to perform such obligations; and

(ii) not interfere with Vertex’s rights under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy Code.



[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would cause competitive harm if publicly disclosed.

(b) All rights, powers and remedies of Vertex provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S. Bankruptcy Code with respect to CRISPR. The Parties agree that they intend the following rights to extend to the maximum extent permitted by Applicable Law, and to be enforceable under U.S. Bankruptcy Code Section 365(n):

(i) the right of access to any intellectual property rights (including all embodiments thereof) of CRISPR, or any Third Party with whom CRISPR contracts to perform an obligation of CRISPR under this Agreement, and, in the case of any such Third Party, which is necessary for the Manufacture, use, sale, import or export of Shared Products; and

Any notices required or permitted under this Agreement that are delivered by Vertex to CRISPR AG pursuant to this Section 16.5 shall be deemed properly delivered hereunder to each of CRISPR UK, CRISPR AG, CRISPR Inc. and Tracr.

16.6. Amendment. No amendment, modification or supplement of any provision of this Agreement will be valid or effective unless made in writing and signed by a duly authorized officer of each of Vertex Parent, Vertex UK and CRISPR AG, CRISPR Inc., CRISPR UK and Tracr.

16.7. Waiver. No provision of this Agreement will be waived by any act, omission or knowledge of a Party or its agents or employees except by an instrument in writing expressly waiving such provision and signed by a duly authorized officer of the waiving Party. The waiver by either of Vertex or CRISPR of any breach of any provision hereof by the other Party will not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself. Written waiver of any provision of this Agreement by of any one of the CRISPR Entities in accordance with this Section 16.7 shall be binding upon each of CRISPR UK, CRISPR AG, CRISPR Inc. and Tracr.

16.8. Severability. If any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same will not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement will be construed as if such clause of portion thereof had never been contained in this Agreement, and there will be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law.

16.10. Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States of America or other countries that may be imposed upon or related to CRISPR or Vertex from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate Governmental Authority.

16.13. Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing herein contained will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

16.14. Interpretation.

16.15. No Third Party Rights or Obligations. No provision of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligations in any Person not a Party to this Agreement.

16.16. Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

## Schedule A

## [***] ARBITRATION

Selection of [***] Expert and Submission of Positions. The Parties will select and agree upon a mutually acceptable independent Third Party expert who is neutral, disinterested and impartial, and has the experience specified in Section 2.8 for the applicable dispute (the “[***] Expert”). If the Parties are unable to mutually agree upon a [***] Expert within [***] days following the delivery of the request for [***] Arbitration, then upon request by either Party, the [***] Expert will be an arbitrator appointed by Judicial and Mediation Services (“JAMS”), which arbitrator need not have the above-described experience. Once the [***] Expert has been selected, each Party will within [***] days following selection of the [***] Expert provide the [***] Expert and the other Party with a written report setting forth its position with respect to the substance of the dispute and may submit a revised or updated report and position to the [***] Expert within [***] days of receiving the other Party’s report. If so requested by the [***] Expert, each Party will make oral submissions to the [***] Expert based on such Party’s written report, and each Party will have the right to be present during any such oral submissions.

JAMS Supervision. In the event the [***] Expert is a JAMS arbitrator selected by JAMS as provided in this Schedule A, the matter will be conducted as a binding arbitration in accordance with JAMS procedures, as modified by this Schedule A (including that the arbitrator will adopt as his or her decision the position of one Party or the other, as described below). In such event, the arbitrator may retain a Third Party expert with the same experience specified in Section 2.8 for the [***] Expert to assist in rendering such decision, and the expenses of any such expert will be shared by the Parties as costs of the arbitration as provided in this Schedule A.

Determination by the [***] Expert. The [***] Expert will, no later than [***] days after the last submission of the written reports and, if any, oral submissions, select one of the Party’s positions as his or her final decision, and will not have the authority to modify either Party’s position or render any substantive decision other than to so select the position of either Party as set forth in their respective written report (as initially submitted, or as revised in accordance with this Schedule A, as applicable). The decision of the [***] Expert will be the sole, exclusive and binding remedy between them regarding the dispute submitted to such [***] Expert.

Location; Costs. Unless otherwise mutually agreed upon by the Parties in writing, the in-person portion (if any) of such proceedings will be conducted in Boston, Massachusetts. [***]

Timetable for Completion in [***] Days. The Parties will use, and will direct the [***] Expert to use, commercially reasonable efforts to resolve a dispute within [***] days after the selection of the [***] Expert, or if resolution within [***] days is not reasonably achievable, as determined by the [***] Expert, then as soon thereafter as is reasonably practicable

WHEREAS, the Company, the other Loan Parties, the Administrative Agent and the Consenting Lenders (constituting the Required Lenders) desire to amend the Existing Credit Agreement as set forth herein to conform certain of its terms, provisions and schedules to the correlative terms and provisions of, and schedules to, the 2020 Credit Agreement; and

WHEREAS, the undersigned Loan Parties, the Administrative Agent and the Consenting Lenders are prepared to amend the Existing Credit Agreement on the terms, subject to the conditions and in reliance on the representations set forth herein.

NOW THEREFORE, in consideration of the premises and other good and valuable consideration, the parties hereto hereby agree as follows:

Section 1. Amendments to Existing Credit Agreement and Certain Schedules to Existing Credit Agreement. Subject to the satisfaction (or waiver by the Administrative Agent with the consent of the Required Lenders) of the conditions precedent set forth in Section 2 of this Amendment, the Existing Credit Agreement and certain Schedules to the Existing Credit Agreement shall be amended, effective as of the Effective Date (as defined below), in the manner provided in this Section 1.



(a) Amendments to Existing Credit Agreement. The Existing Credit Agreement is hereby amended to delete the stricken text (indicated textually in the same manner as the following example: stricken-text) and to add the double-underlined text (indicated textually in the same manner as the following example: double-underlined text) as set forth in the pages of the Amended Credit Agreement attached as Annex A hereto.

(b) Amendments to Schedule 5.18(a) to Existing Credit Agreement. Schedule 5.18(a) to the Existing Credit Agreement is hereby amended and restated in its entirety by replacing such schedule with the new Schedule 5.18(a) attached as Annex B hereto.

Section 2. Condition Precedent. This Amendment shall become effective when the following conditions precedent have been satisfied (or waived by the Administrative Agent with the consent of the Required Lenders) (the “Effective Date”):

(a) Documentation. The Administrative Agent (or its counsel) shall have received counterparts of this Amendment (which may include delivery of an executed counterpart of a signature page to this Amendment by fax transmission, e-mail transmission or other electronic transmission in accordance with Section 8 of this Amendment) duly authorized and executed by (i) each Loan Party, (ii) the Administrative Agent and (iii) the Consenting Lenders representing at least the Required Lenders.

(b) No Default or Event of Default. No Default or Event of Default exists or will result after giving effect to this Amendment on the date hereof.

Section 3. Representations and Warranties; Reaffirmation of Grant. Each Loan Party hereby represents and warrants to the Administrative Agent and the Lenders that, as of the date hereof and immediately after giving effect to this Amendment, (a) the representations and warranties of the Company and each other Loan Party contained in Article V of the Amended Credit Agreement are (a) with respect to representations and warranties that contain a materiality qualification, true and correct in all respects on and as of the date hereof, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date and (b) with respect to representations and warranties that do not contain a materiality qualification, true and correct in all material respects on and as of the date hereof, except that for purposes hereof, the representations and warranties contained in



Sections 5.05(a) and (b) of the Amended Credit Agreement shall be deemed to refer to the most recent statements furnished pursuant to Sections 6.01(a) and (b) of the Amended Credit Agreement, respectively, (b) no Default or Event of Default has occurred and is continuing or will result after giving effect to this Amendment, and (c) the Amended Credit Agreement and each other Loan Document constitute a legal, valid and binding obligation of such Loan Party, enforceable against each Loan Party that is party thereto in accordance with its terms, subject to applicable bankruptcy, insolvency, examinership, reorganization, moratorium or other laws affecting creditors' rights generally and subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 4. Survival of Representations and Warranties. All representations and warranties made in this Amendment shall survive the execution and delivery of this Amendment, and no investigation by the Administrative Agent or the Lenders shall affect the representations and warranties or the right of the Administrative Agent and the Lenders to rely upon them.

Section 5. Effect on Loan Documents. On and after the Effective Date, (a) this Amendment constitutes a “Loan Document” under the Amended Credit Agreement and (b) each reference in the Amended Credit Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or words of like import referring to the Existing Credit Agreement, and each reference in the other Loan Documents to “Credit Agreement”, “thereunder”, “thereof” or words of like import referring to the Existing Credit Agreement shall mean and be a reference to the Amended Credit Agreement, and this Amendment and the Amended Credit Agreement shall be read together and construed as a single instrument.

Section 6. Costs and Expenses. The Borrower shall pay all reasonable and documented or invoiced out-of-pocket expenses incurred by the Administrative Agent (including the reasonable and documented or invoiced out-of-pocket fees, charges and disbursements of one primary counsel for the Administrative Agent) incurred in connection with the preparation, negotiation, execution and delivery of this Amendment, in each case, in accordance with Section 11.04(a) of the Amended Credit Agreement.

Section 7. Governing Law. THIS AMENDMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AMENDMENT OR ANY OTHER LOAN DOCUMENT (EXCEPT, AS TO ANY OTHER LOAN DOCUMENT, AS EXPRESSLY SET FORTH THEREIN) AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Section 8. Execution. This Amendment may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Amendment by fax transmission or e-mail transmission (e.g., “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Amendment. The words “delivery,” “execute,” “execution,” “signed,” “signature,” and words of



like import in this Amendment or any other document executed in connection herewith shall be deemed to include electronic signatures, the electronic matching of assignment terms and contract formations on electronic platforms approved by the Administrative Agent, or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable Law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

Section 9. Limited Effect. This Amendment relates only to the specific matters expressly covered herein, shall not be considered to be an amendment or waiver of any rights or remedies that the Administrative Agent or any Lender may have under the Existing Credit Agreement, under any other Loan Document (except as expressly set forth herein) or under Law, and shall not be considered to create a course of dealing or to otherwise obligate in any respect the Administrative Agent or any Lender to execute similar or other amendments or waivers or grant any amendments or waivers under the same or similar or other circumstances in the future.

Section 10. Reaffirmation by Guarantors. Each of the Guarantors (other than the Company) acknowledges that its consent to this Amendment is not required, but each of the undersigned nevertheless does hereby agree and consent to this Amendment and to the documents and agreements referred to herein. Each of the Guarantors agrees and acknowledges that (a) notwithstanding the effectiveness of this Amendment, such Guarantor’s Guaranty shall remain in full force and effect without modification thereto and (b) nothing herein shall in any way limit any of the terms or provisions of such Guarantor’s Guaranty or any other Loan Document executed by such Guarantor (as the same may be amended from time to time), all of which are hereby ratified, confirmed and affirmed in all respects. Each of the Guarantors hereby agrees and acknowledges that no other agreement, instrument, consent or document shall be required to give effect to this Section 10.

The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise, (i) any definition of or reference to any agreement, instrument or other document (including the Loan Documents and any Organization Document) shall be construed as referring to such agreement, instrument or other document as from time to time amended, amended and restated, modified, extended, restated, replaced or supplemented from time to time (subject to any restrictions on such amendments, supplements or modifications set forth herein or in any other Loan Document), (ii) any reference herein to any Person shall be construed to include such Person’s successors and assigns, (iii) the words “hereto,” “herein,” “hereof” and “hereunder,” and words of similar import when used in any Loan Document, shall be construed to refer to such Loan Document in its entirety and not to any particular provision thereof, (iv) all references in a Loan Document to Articles, Sections, Preliminary Statements, Exhibits and Schedules shall be construed to refer to Articles and Sections of, and Preliminary Statements, Exhibits and Schedules to, the Loan Document in which such references appear, (v) any reference to any law shall include all statutory and regulatory rules, regulations, orders and provisions consolidating, amending, replacing or interpreting such law and any reference to any law, rule or regulation shall, unless otherwise specified, refer to such law, rule or regulation as amended, modified, extended, restated, replaced or supplemented from time to time, and (vi) the words “asset” and “property” shall be construed to have the same meaning and effect and to refer to any and all tangible and intangible assets and properties, including cash, securities, accounts and contract rights. Any and all references to “Borrower” regardless of whether preceded by the term “a”, “any”, “each of”, “all”, “and/or”, or any other similar term shall be deemed to refer, as the context requires, to each and every (and/or any, one or all) parties constituting a Borrower, individually and/or in the aggregate.

(b) In the computation of periods of time from a specified date to a later specified date, the word “from” means “from and including;” the words “to” and “until” each mean “to but excluding;” and the word “through” means “to and including.”

(c) Section headings herein and in the other Loan Documents are included for convenience of reference only and shall not affect the interpretation of this Agreement or any other Loan Document.

(d) Any reference herein to a merger, transfer, consolidation, amalgamation, assignment, sale, disposition or transfer, or similar term, shall be deemed to apply to a division of or by a limited liability company, or an allocation of assets to a series of a



limited liability company (or the unwinding of such a division or allocation), as if it were a merger, transfer, consolidation, amalgamation, assignment, sale, disposition or transfer, or similar term, as applicable, to, of or with a separate Person. Any division of a limited liability company shall constitute a separate Person hereunder (and each division of any limited liability company that is a Subsidiary, joint venture or any other like term shall also constitute such a Person or entity).

## 1.03 Accounting Terms.

(a) Generally. All accounting terms not specifically or completely defined herein shall be construed in conformity with, and all financial data (including financial ratios and other financial calculations) required to be submitted pursuant to this Agreement shall be prepared in conformity with, GAAP applied on a consistent basis, as in effect from time to time, applied in a manner consistent with that used in preparing the Audited Financial Statements, except as otherwise specifically prescribed herein. Notwithstanding the foregoing, for purposes of determining compliance with any covenant (including the computation of any financial covenant) contained herein, Indebtedness of the Company and its Restricted Subsidiaries shall be deemed to be carried at 100% of the outstanding principal amount thereof, and the effects of FASB ASC 825 and FASB ASC 470-20 on financial liabilities shall be disregarded.

(b) Changes in GAAP. If at any time any change in GAAP or application thereof (including the adoption of IFRS) would affect the computation of any financial ratio or requirement set forth in any Loan Document, and either the Company or the Required Lenders shall so request, the Administrative Agent, the Lenders and the Company shall negotiate in good faith, each acting reasonably (and without requirement of any fee), to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP or application thereof (subject to the approval of the Required Lenders); provided that, until so amended, (i) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein or the application thereof (without regard to such change or adoption of IFRS) and (ii) the Company shall provide to the Administrative Agent and the Lenders the financial statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP.

(c) Lease Accounting. Notwithstanding any other provision contained herein, each financial covenant, ratio, accounting definition or requirement used herein shall be construed, and all computations of amounts and ratios referred to herein shall be made, without giving effect to the adoption of Accounting Standards Updated No. 2016-02 (“ASU 2016-02”) by the Financial Accounting Standards Board such that “Capitalized Leases” shall specifically exclude liabilities that were considered operating lease liabilities under GAAP prior to the adoption of ASU 2016-02; provided that all financial statements delivered pursuant to this Agreement shall, if applicable and solely to the extent reasonably requested by the Administrative Agent, be accompanied by a schedule



showing any adjustments necessary to reconcile such financial statements with GAAP prior to the adoption of ASU 2016-02, with respect to such lease liabilities.

(d) Consolidation of Variable Interest Entities. All references herein to Consolidated financial statements of the Company and its Subsidiaries or to the determination of any amount for the Company and its Subsidiaries on a Consolidated basis or any similar reference shall, in each case, be deemed to exclude each variable interest entity that the Company is required to otherwise consolidate pursuant to FASB ASC 810.

(e) Pro Forma Treatment. Each Disposition of all or substantially all of a line of business, and each Acquisition, by the Company and its Subsidiaries that is consummated during any Measurement Period shall, for purposes of determining compliance with the financial covenants set forth in Section 7.11 and for purposes of determining the Applicable Rate, be given Pro Forma Effect as of the first day of such Measurement Period.

## 1.04 Rounding.

Any financial ratios required to be maintained by the Company pursuant to this Agreement shall be calculated by dividing the appropriate component by the other component, carrying the result to one place more than the number of places by which such ratio is expressed herein and rounding the result up or down to the nearest number (with a rounding-up if there is no nearest number).

## 1.05 Times of Day.

Unless otherwise specified, all references herein to times of day shall be references to Eastern time (daylight or standard, as applicable).

## 1.06 Letter of Credit Amounts.

Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be deemed to be the Dollar Equivalent of the stated amount of such Letter of Credit in effect at such time; provided, however, that with respect to any Letter of Credit that, by its terms or the terms of any Issuer Document related thereto, provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the Dollar Equivalent of the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at such time.

## 1.07 UCC Terms.

Terms defined in the UCC in effect on the Closing Date and not otherwise defined herein shall, unless the context otherwise indicates, have the meanings provided by those definitions. Subject to the foregoing, the term “UCC” refers, as of any date of determination, to the UCC then in effect.



## 1.08 Exchange Rates; Currency Equivalents.

(a) The Administrative Agent or the applicable L/C Issuer, as applicable, shall determine the Spot Rates as of each Revaluation Date to be used for calculating Dollar Equivalent amounts of Credit Extensions and Outstanding Amounts denominated in Alternative Currencies. Such Spot Rates shall become effective as of such Revaluation Date and shall be the Spot Rates employed in converting any amounts between the applicable currencies until the next Revaluation Date to occur. Except for purposes of financial statements delivered by Loan Parties hereunder or calculating financial covenants hereunder or except as otherwise provided herein, the applicable amount of any currency (other than Dollars) for purposes of the Loan Documents shall be such Dollar Equivalent amount as so determined by the Administrative Agent or the applicable L/C Issuer, as applicable.

(b) Wherever in this Agreement in connection with a Borrowing, conversion, continuation or prepayment of a Eurocurrency Rate Loan or the issuance, amendment or extension of a Letter of Credit, an amount, such as a required minimum or multiple amount, is expressed in Dollars, but such Borrowing, Eurocurrency Rate Loan or Letter of Credit is denominated in an Alternative Currency, such amount shall be the relevant Alternative Currency Equivalent of such Dollar amount (rounded to the nearest unit of such Alternative Currency, with 0.5 of a unit being rounded upward), as determined by the Administrative Agent or the applicable L/C Issuer, as the case may be.

(c) The Administrative Agent does not warrant, nor accept responsibility, nor shall the Administrative Agent have any liability with respect to the administration, submission or any other matter related to the rates in the definition of “Eurocurrency Rate” or with respect to any rate that is an alternative or replacement for or successor to any of such rates (including, without limitation, any LIBOR Successor Rate) or the effect of any of the foregoing, or of any LIBOR Successor Rate Conforming Changes.

(d) Any amount specified in this Agreement (other than in Articles II, IX and X) or any of the other Loan Documents to be in Dollars shall also include the equivalent of such amount in any currency other than Dollars, such equivalent amount thereof in the applicable currency to be determined by the Administrative Agent at such time on the basis of the Spot Rate (as defined below) for the purchase of such currency with Dollars. For purposes of this Section 1.08, the “Spot Rate” for a currency means the rate determined by the Administrative Agent to be the rate quoted by the Person acting in such capacity as the spot rate for the purchase by such Person of such currency with another currency through its principal foreign exchange trading office at approximately 11:00 a.m. on the date two (2) Business Days prior to the date of such determination; provided that the Administrative Agent may obtain such Spot Rate from another financial institution designated by the Administrative Agent if the Person acting in such capacity does not have as of the date of determination a spot buying rate for any such currency.



## 1.09 Additional Alternative Currencies.

(a) The Company may from time to time request that Eurocurrency Rate Loans be made and/or Letters of Credit be issued in a currency other than those specifically listed in the definition of “Alternative Currency”; provided that (i) such requested currency is an Eligible Currency and (ii) such requested currency shall only be treated as a “LIBOR Quoted Currency” to the extent that there is published LIBOR rate for such currency. In the case of any such request with respect to the making of Eurocurrency Rate Loans, such request shall be subject to the approval of the Administrative Agent and each Lender with a Revolving Commitment under which such currency is requested to be made available; and in the case of any such request with respect to the issuance of Letters of Credit, such request shall be subject to the approval of the Administrative Agent and the applicable L/C Issuer.

(b) Any such request shall be made to the Administrative Agent not later than 11:00 a.m., twenty (20) Business Days prior to the date of the desired Credit Extension (or such other time or date as may be agreed by the Administrative Agent and, in the case of any such request pertaining to Letters of Credit, the L/C Issuers, in its or their sole discretion). In the case of any such request pertaining to Eurocurrency Rate Loans, the Administrative Agent shall promptly notify each Appropriate Lender thereof; and in the case of any such request pertaining to Letters of Credit, the Administrative Agent shall promptly notify the L/C Issuers thereof. Each Appropriate Lender (in the case of any such request pertaining to Eurocurrency Rate Loans) or the L/C Issuers (in the case of a request pertaining to Letters of Credit) shall notify the Administrative Agent, not later than 11:00 a.m., ten (10) Business Days after receipt of such request whether it consents, in its sole discretion, to the making of Eurocurrency Rate Loans or the issuance of Letters of Credit, as the case may be, in such requested currency.

(c) Any failure by a Lender or any L/C Issuer, as the case may be, to respond to such request within the time period specified in the preceding sentence shall be deemed to be a refusal by such Lender or such L/C Issuer, as the case may be, to permit Eurocurrency Rate Loans to be made or Letters of Credit to be issued in such requested currency. If the Administrative Agent and all the Appropriate Lenders consent to making Eurocurrency Rate Loans in such requested currency and the Administrative Agent and such Lenders reasonably determine that an appropriate interest rate is available to be used for such requested currency, the Administrative Agent shall so notify the Company and (i) the Administrative Agent and such Lenders may amend the definition of Eurocurrency Rate for any Non-LIBOR Quoted Currency to the extent necessary to add the applicable Eurocurrency Rate for such currency and (ii) to the extent the definition of Eurocurrency Rate reflects the appropriate interest rate for such currency or has been amended to reflect the appropriate rate for such currency, such currency shall thereupon be deemed for all purposes to be an Alternative Currency for purposes of any Borrowings of Eurocurrency Rate Loans. If the Administrative Agent and the L/C Issuers consent to the issuance of Letters of Credit in such requested currency, the Administrative Agent shall so notify the Company and (iii) the Administrative Agent and the L/C Issuers may amend the



definition of Eurocurrency Rate for any Non-LIBOR Quoted Currency to the extent necessary to add the applicable Eurocurrency Rate for such currency and (iv) to the extent the definition of Eurocurrency Rate reflects the appropriate interest rate for such currency or has been amended to reflect the appropriate rate for such currency, such currency shall thereupon be deemed for all purposes to be an Alternative Currency, for purposes of any Letter of Credit issuances. If the Administrative Agent shall fail to obtain consent to any request for an additional currency under this Section 1.09, the Administrative Agent shall promptly so notify the Company. Any specified currency of an Existing Letter of Credit that is neither Dollars nor one of the Alternative Currencies specifically listed in the definition of “Alternative Currency” shall be deemed an Alternative Currency with respect to such Existing Letter of Credit only.

## 1.10 Change of Currency.

(a) Each obligation of the Borrowers to make a payment denominated in the national currency unit of any member state of the European Union that adopts the Euro as its lawful currency after the date hereof shall be redenominated into Euro at the time of such adoption. If, in relation to the currency of any such member state, the basis of accrual of interest expressed in this Agreement in respect of that currency shall be inconsistent with any convention or practice in the London interbank market for the basis of accrual of interest in respect of the Euro, such expressed basis shall be replaced by such convention or practice with effect from the date on which such member state adopts the Euro as its lawful currency; provided that, if any Borrowing in the currency of such member state is outstanding immediately prior to such date, such replacement shall take effect, with respect to such Borrowing, at the end of the then current Interest Period.

(b) Each provision of this Agreement shall be subject to such reasonable changes of construction as the Administrative Agent may from time to time specify to be appropriate to reflect the adoption of the Euro by any member state of the European Union and any relevant market conventions or practices relating to the Euro.

(c) Each provision of this Agreement also shall be subject to such reasonable changes of construction as the Administrative Agent may from time to time specify to be appropriate to reflect a change in currency of any other country and any relevant market conventions or practices relating to the change in currency.

## ARTICLE II

## COMMITMENTS AND CREDIT EXTENSIONS

2.01 Revolving Loans. Subject to the terms and conditions set forth herein, each Revolving Lender severally agrees to make loans (each such loan, a “Revolving Loan”) to the Borrowers, in Dollars or in one or more Alternative Currencies, from time to time, on any Business Day during the Availability Period, in an aggregate amount not to exceed at any time outstanding the amount of such Lender’s Revolving Commitment; provided, however, that after giving effect to any Revolving Borrowing, (a) the Total Revolving



Outstandings shall not exceed the Aggregate Revolving Commitments, (b) the Revolving Exposure of any Lender shall not exceed such Revolving Lender's Revolving Commitment, (c) the Revolving Exposure of any Lender under any Class of Revolving Commitments shall not exceed such Lender's Revolving Commitment of such Class, and (d) the aggregate Outstanding Amount of all Loans denominated in Alternative Currencies shall not exceed the Alternative Currency Sublimit. Within the limits of each Revolving Lender's Revolving Commitment, and subject to the other terms and conditions hereof, the Borrowers may borrow Revolving Loans, prepay under Section 2.05, and reborrow under this Section 2.01. Revolving Loans may be Base Rate Loans or Eurocurrency Rate Loans, as further provided herein; provided, however, any Revolving Borrowings made on the Closing Date or any of the three (3) Business Days (or such longer applicable period, in accordance with Section 2.02(a), for Revolving Borrowings denominated in Alternative Currencies other than Euro or Sterling) following the Closing Date shall be made as Base Rate Loans unless the Company delivers a Funding Indemnity Letter not less than three (3) Business Days (or such longer applicable period, in accordance with Section 2.02(a), for Revolving Borrowings denominated in Alternative Currencies other than Euro or Sterling) prior to the date of such Revolving Borrowing.

## 2.02 Borrowings, Conversions and Continuations of Loans.

(a) Notice of Borrowing. Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Eurocurrency Rate Loans shall be made upon the applicable Borrower's irrevocable notice to the Administrative Agent, which may be given by: (i) telephone or (ii) a Loan Notice; provided that any telephonic notice must be confirmed immediately by delivery to the Administrative Agent of a Loan Notice. Each such Loan Notice must be received by the Administrative Agent not later than 11:00 a.m. (A) three (3) Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Eurocurrency Rate Loans denominated in Dollars, Euro or Sterling, or of any conversion of Eurocurrency Rate Loans denominated in Dollars to Base Rate Loans, (B) four (4) Business Days (or five (5) Business Days in the case of a Special Notice Currency) prior to the requested date of any Borrowing or continuation of Eurocurrency Rate Loans denominated in other Alternative Currencies, and (C) on the requested date of any Borrowing of Base Rate Loans; provided, however, that if the applicable Borrower wishes to request Eurocurrency Rate Loans having an Interest Period other than one (1), two (2), three (3) or six (6) months in duration as provided in the definition of “Interest Period”, the applicable notice must be received by the Administrative Agent not later than 11:00 a.m. (x) four (4) Business Days prior to the requested date of such Borrowing, conversion or continuation of Eurocurrency Rate Loans denominated in Dollars, Euro or Sterling, or (y) five (5) Business Days (or six (6) Business Days in the case of a Special Notice Currency) prior to the requested date of such Borrowing, conversion or continuation of Eurocurrency Rate Loans denominated in other Alternative Currencies, whereupon the Administrative Agent shall give prompt notice to the Appropriate Lenders of such request and determine whether the requested Interest Period is acceptable to all of them. Not later than 11:00 a.m., (1) three (3)



Business Days before the requested date of such Borrowing, conversion or continuation of Eurocurrency Rate Loans denominated in Dollars, Euro or Sterling, or (2) four (4) Business Days (or five (5) Business Days in the case of a Special Notice Currency) prior to the requested date of such Borrowing, conversion or continuation of Eurocurrency Rate Loans denominated in other Alternative Currencies, the Administrative Agent shall notify the applicable Borrower (which notice may be by telephone) whether or not the requested Interest Period has been consented to by all the Lenders. Each Borrowing of, conversion to or continuation of Eurocurrency Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Except as provided in Sections 2.03(c) and 2.04(c), each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each Loan Notice and each telephonic notice shall specify (I) whether the applicable Borrower is requesting a Borrowing, a conversion of Loans from one Type to the other, or a continuation of Loans, as the case may be, (II) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (III) the principal amount of Loans to be borrowed, converted or continued, (IV) the Type of Loans to be borrowed or to which existing Loans are to be converted, (V) if applicable, the duration of the Interest Period with respect thereto, (VI) the currency of the Loans to be borrowed and (VII) the relevant Borrower requesting such Borrowing. If the applicable Borrower fails to specify a currency in a Loan Notice requesting a Borrowing, then the Loans so requested shall be made in Dollars. If the applicable Borrower fails to specify a Type of Loan in a Loan Notice or if the applicable Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate Loans; provided, however, that in the case of a failure to timely request a continuation of Loans denominated in an Alternative Currency, such Loans shall be continued as Eurocurrency Rate Loans in their original currency with an Interest Period of one (1) month. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurocurrency Rate Loans. If the applicable Borrower requests a Borrowing of, conversion to, or continuation of Eurocurrency Rate Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one (1) month. Notwithstanding anything to the contrary herein, each Swingline Loan shall be made as a Base Rate Loan and may not be converted to a Eurocurrency Rate Loan. Except as provided pursuant to Section 2.12(a), no Loan may be converted into or continued as a Loan denominated in a different currency, but instead must be repaid in the original currency of such Loan and reborrowed in the other currency.

(b) Advances. Following receipt of a Loan Notice, the Administrative Agent shall promptly notify each Appropriate Lender of the amount (and currency) of its Applicable Percentage of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the applicable Borrower, the Administrative Agent shall notify each Appropriate Lender of the details of any automatic conversion to Base Rate Loans or continuation of Loans denominated in a currency other than Dollars, in each case as described in Section 2.02(a). In the case of a Borrowing, each Appropriate



Lender shall make the amount of its Loan available to the Administrative Agent in Same Day Funds at the Administrative Agent’s Office for the applicable currency not later than 1:00 p.m., in the case of any Loan denominated in Dollars, and not later than the Applicable Time specified by the Administrative Agent in the case of any Loan in an Alternative Currency, in each case on the Business Day specified in the applicable Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01, or, if applicable, Section 2.19), the Administrative Agent shall make all funds so received available to the applicable Borrower in like funds as received by the Administrative Agent either by (i) crediting the account of the applicable Borrower on the books of Bank of America with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Administrative Agent by the applicable Borrower; provided, however, that if, on the date a Loan Notice with respect to a Revolving Borrowing is given by the applicable Borrower, there are L/C Borrowings outstanding, then the proceeds of such Revolving Borrowing, first, shall be applied to the payment in full of any such L/C Borrowings, and second, shall be made available to the applicable Borrower as provided above; provided further, however, that no Revolving Borrowing by a Designated Foreign Borrower shall be used to pay any L/C Borrowings of or attributable to any U.S. Loan Party (or any other Domestic Subsidiary).

(c) Eurocurrency Rate Loans. Except as otherwise provided herein, a Eurocurrency Rate Loan may be continued or converted only on the last day of an Interest Period for such Eurocurrency Rate Loan. During the existence of an Event of Default, no Loans may be requested as, converted to or continued as Eurocurrency Rate Loans without the consent of the Required Lenders, and the Required Lenders may demand that any or all of the outstanding Eurocurrency Rate Loans denominated in Dollars be converted immediately to Base Rate Loans and any or all of the then outstanding Eurocurrency Rate Loans denominated in an Alternative Currency be prepaid, or redenominated into Dollars in the amount of the Dollar Equivalent thereof, on the last day of the then current Interest Period with respect thereto.

(d) Interest Rates. Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrowers and the Lenders in the absence of manifest error.

(e) Interest Periods. After giving effect to all Revolving Borrowings, all conversions of Revolving Loans from one Type to the other, and all continuations of Revolving Loans as the same Type, there shall not be more than ten (10) Interest Periods in effect in respect of the Revolving Facility.

(f) Cashless Settlement Mechanism. Notwithstanding anything to the contrary in this Agreement, any Lender may exchange, continue or rollover all or a portion of its Loans in connection with any refinancing, extension, incremental increase, loan modification or similar transaction permitted by the terms of this Agreement,



pursuant to a cashless settlement mechanism approved by the Company, the Administrative Agent and such Lender.

## 2.03 Letters of Credit.

## (a) The Letter of Credit Commitment.

(i) Subject to the terms and conditions set forth herein, (A) each L/C Issuer agrees, in reliance upon the agreements of the Revolving Lenders set forth in this Section 2.03, (1) from time to time on any Business Day during the period from the Closing Date until the applicable Letter of Credit Expiration Date, to issue Letters of Credit denominated in Dollars or in one or more Alternative Currencies for the account of any Borrower or any of its Restricted Subsidiaries, and to amend or extend Letters of Credit previously issued by it, in accordance with Section 2.03(b) and (2) to honor drawings under the Letters of Credit; and (B) the Revolving Lenders severally agree to participate in Letters of Credit issued for the account of any Borrower or its Restricted Subsidiaries and any drawings thereunder; provided that after giving effect to any L/C Credit Extension with respect to any Letter of Credit, (x) the Total Revolving Outstandings shall not exceed the Aggregate Revolving Commitments, (y) the Revolving Exposure of any Revolving Lender shall not exceed such Lender's Revolving Commitment and (z) the Outstanding Amount of the L/C Obligations shall not exceed the Letter of Credit Sublimit; and provided further that no Letter of Credit denominated in any Alternative Currency may be issued by any L/C Issuer other than Bank of America, through itself or through one of its designated Affiliates or branch offices, in its capacity as such. Each request by a Borrower for the issuance or amendment of a Letter of Credit shall be deemed to be a representation by such Borrower that the L/C Credit Extension so requested complies with the conditions set forth in the proviso to the preceding sentence. Within the foregoing limits, and subject to the terms and conditions hereof, the Borrowers' ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrowers may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed in accordance with the terms hereof. All Existing Letters of Credit shall be deemed to have been issued pursuant hereto and deemed L/C Obligations, and from and after the Closing Date shall be subject to and governed by the terms and conditions hereof.

## (ii) No L/C Issuer shall issue any Letter of Credit if:

(A) subject to Section 2.03(b)(iv), the expiry date of the requested Letter of Credit would occur more than twelve (12) months after the date of issuance or last extension, unless the Administrative Agent and such L/C Issuer have approved such expiry date; or



(B) the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless the Administrative Agent and such L/C Issuer have approved such expiry date (it being understood that in the event the expiry date of any requested Letter of Credit would occur after the Letter of Credit Expiration Date, from and after the Letter of Credit Expiration Date, the Borrowers shall immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations in respect of such Letters of Credit in accordance with Section 2.14);

(iii) No L/C Issuer shall be under any obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such L/C Issuer from issuing the Letter of Credit, or any Law applicable to such L/C Issuer or any request or directive (whether or not having the force of Law) from any Governmental Authority with jurisdiction over such L/C Issuer shall prohibit, or request that such L/C Issuer refrain from, the issuance of letters of credit generally or the Letter of Credit in particular or shall impose upon such L/C Issuer with respect to the Letter of Credit any restriction, reserve or capital requirement (for which such L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which such L/C Issuer in good faith deems material to it;

(B) the issuance of the Letter of Credit would violate one or more policies of such L/C Issuer applicable to letters of credit generally;

(C) except as otherwise agreed by the Administrative Agent and such L/C Issuer, the Letter of Credit is in an initial stated amount less than $50,000;

(D) except as otherwise agreed by the Administrative Agent and such L/C Issuer, the Letter of Credit is to be denominated in a currency other than Dollars or an Alternative Currency;

(E) any Revolving Lender is at that time a Defaulting Lender, unless such L/C Issuer has entered into arrangements, including the delivery of Cash Collateral, satisfactory to such L/C Issuer (in its sole discretion) with the applicable Borrowers or such Revolving Lender to eliminate such L/C Issuer's actual or potential Fronting Exposure (after giving effect to Section 2.15(a)(iv)) with respect to the Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other L/C Obligations as to which such L/C Issuer



has actual or potential Fronting Exposure, as it may elect in its sole discretion;

(F) the Letter of Credit contains any provisions for automatic reinstatement of the stated amount after any drawing thereunder;

(G) such L/C Issuer does not as of the issuance date of the requested Letter of Credit issue Letters of Credit in the requested currency; or

(H) the requested Letter of Credit is to be issued for the benefit of an Irish beneficiary.

(iv) No L/C Issuer shall amend any Letter of Credit if such L/C Issuer would not be permitted at such time to issue the Letter of Credit in its amended form under the terms hereof.

(v) No L/C Issuer shall be under any obligation to amend any Letter of Credit if (A) such L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to the Letter of Credit.

(vi) Each L/C Issuer shall act on behalf of the Revolving Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and such L/C Issuer shall have all of the benefits and immunities (A) provided to the Administrative Agent in Article IX with respect to any acts taken or omissions suffered by such L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and Issuer Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article IX included such L/C Issuer with respect to such acts or omissions, and (B) as additionally provided herein with respect to the L/C Issuers.

## (b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension Letters of Credit.

(i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of a Borrower delivered to the applicable L/C Issuer (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of such Borrower and/or its Restricted Subsidiary, as required by such L/C Issuer. Such Letter of Credit Application may be sent by facsimile, by mail, by overnight courier, by electronic transmission using the system provided by the applicable L/C Issuer, by personal delivery or by any other means reasonably acceptable to such L/C Issuer. Such Letter of Credit Application must be received by the applicable L/C Issuer and the Administrative Agent not later than 11:00 a.m. at least five (5) Business



Days (or such later date and time as the Administrative Agent and such L/C Issuer may agree in a particular instance in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the applicable L/C Issuer: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount and currency thereof and in the absence of specification of currency shall be deemed a request for a Letter of Credit denominated in Dollars; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; (G) the purpose and nature of the requested Letter of Credit; and (H) such other matters as such L/C Issuer may reasonably require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to the applicable L/C Issuer: (1) the Letter of Credit to be amended; (2) the proposed date of amendment thereof (which shall be a Business Day); (3) the nature of the proposed amendment; and (4) such other matters as such L/C Issuer may require. Additionally, the Borrowers shall furnish to the applicable L/C Issuer and the Administrative Agent such other documents and information pertaining to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as such L/C Issuer or the Administrative Agent may require.

(ii) Promptly after receipt of any Letter of Credit Application, the applicable L/C Issuer will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the applicable Borrower and, if not, such L/C Issuer will provide the Administrative Agent with a copy thereof. Unless the applicable L/C Issuer has received written notice from any Revolving Lender, the Administrative Agent or any Loan Party, at least one (1) Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in Article IV shall not then be satisfied, then, subject to the terms and conditions hereof, such L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the applicable Borrower (or its applicable Restricted Subsidiary) or enter into the applicable amendment, as the case may be, in each case in accordance with such L/C Issuer's usual and customary business practices. Immediately upon the issuance of each Letter of Credit, each Revolving Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the applicable L/C Issuer a risk participation in such Letter of Credit in an amount equal to the product of such Revolving Lender's Applicable Revolving Percentage (determined without regard to any Class or Classes of Revolving Commitments of such Lender) times the amount of such Letter of Credit.



(iii) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the applicable L/C Issuer will also deliver to the Company and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

(iv) If the applicable Borrower so requests in any applicable Letter of Credit Application (or the amendment of an outstanding Letter of Credit), the applicable L/C Issuer may, in its sole discretion, agree to issue a standby Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit such L/C Issuer to prevent any such extension at least once in each twelve (12) month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve (12) month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the applicable L/C Issuer, the applicable Borrower shall not be required to make a specific request to such L/C Issuer for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Revolving Lenders shall be deemed to have authorized (but may not require) the applicable L/C Issuer to permit the extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date; provided that, a Letter of Credit may, upon the request of the applicable Borrower, be renewed for a period beyond the Letter of Credit Expiration Date subject to the provisions of Section 2.03(a)(ii)(B); provided, however, that such L/C Issuer shall not permit any such extension if (A) such L/C Issuer has determined that it would not be permitted, or would have no obligation at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of Section 2.03(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is seven (7) Business Days before the Non-Extension Notice Date (1) from the Administrative Agent that the Required Lenders have elected not to permit such extension or (2) from the Administrative Agent, any Revolving Lender or any Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied, and in each such case directing such L/C Issuer not to permit such extension.

## (c) Drawings and Reimbursements; Funding of Participations.

(i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the applicable L/C Issuer shall notify the applicable Borrower and the Administrative Agent thereof; provided that any failure to give or delay in giving such notice shall not relieve the applicable Borrower of its obligation to reimburse such L/C Issuer and the Lenders with respect to any drawing under any Letter of Credit. The applicable



Borrower shall reimburse the applicable L/C Issuer for all drawings under any Letter of Credit in Dollars, unless, in the case of a Letter of Credit denominated in an Alternative Currency, (A) such L/C Issuer (at its option) shall have specified in such notice that it will require reimbursement in such Alternative Currency, or (B) in the absence of any such requirement for reimbursement in such Alternative Currency, the applicable Borrower shall have notified such L/C Issuer promptly following receipt of the notice of drawing that such Borrower will reimburse such L/C Issuer in such Alternative Currency. In the case of any such reimbursement in Dollars of a drawing under a Letter of Credit denominated in an Alternative Currency, the applicable L/C Issuer shall notify the applicable Borrower of the Dollar Equivalent of the amount of the drawing promptly following the determination thereof. If such Borrower shall have received such notice from the applicable L/C Issuer on or prior to 11:00 a.m. on the date of payment by the applicable L/C Issuer under a Letter of Credit to be reimbursed in Dollars, not later than 4:00 p.m. on such date of payment by the applicable L/C Issuer, or, if such Borrower shall have received such notice later than 11:00 a.m. on the date of payment by the applicable L/C Issuer under a Letter of Credit to be reimbursed in Dollars, not later than 11:00 a.m. on the immediately following Business Day, or the Applicable Time on the date of any payment by such L/C Issuer under a Letter of Credit to be reimbursed in an Alternative Currency (each such date, an “Honor Date”), the applicable Borrower shall reimburse such L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing and in the applicable currency. In the event that (A) a drawing denominated in an Alternative Currency is to be reimbursed in Dollars and (B) the Dollar amount paid by the applicable Borrower, whether on or after the Honor Date, shall not be adequate on the date of that payment to purchase in accordance with normal banking procedures a sum denominated in the Alternative Currency equal to the drawing, such Borrower agrees, as a separate and independent obligation, to indemnify the applicable L/C Issuer for the loss resulting from its inability on that date to purchase the Alternative Currency in the full amount of the drawing. If such Borrower fails to so reimburse such L/C Issuer by such time, the Administrative Agent shall promptly notify each Revolving Lender of the Honor Date, the amount of the unreimbursed drawing (expressed in Dollars in an amount equal to the Dollar Equivalent thereof in the case of a Letter of Credit denominated in an Alternative Currency) (the “Unreimbursed Amount”), and the amount of such Revolving Lender’s Applicable Revolving Percentage thereof. In such event, the Borrowers shall be deemed to have requested a Revolving Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Revolving Commitments and the conditions set forth in Section 4.02 (other than the delivery of a Loan Notice). Any notice given by any L/C Issuer or the Administrative Agent pursuant to this Section 2.03(c)(i) may be given by telephone if immediately confirmed in writing;



provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Revolving Lender shall upon any notice pursuant to Section 2.03(c)(i) make funds available (and the Administrative Agent may apply Cash Collateral provided for this purpose) for the account of the applicable L/C Issuer, in Dollars, at the Administrative Agent's Office in an amount equal to its Applicable Revolving Percentage (determined without regard to any separate Class or Classes of Revolving Commitments of such Lender) of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.03(c)(ii), each Revolving Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Company in such amount. The Administrative Agent shall remit the funds so received to the applicable L/C Issuer in Dollars.

(iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Revolving Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, the applicable Borrower shall be deemed to have incurred from the applicable L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Revolving Lender's payment to the Administrative Agent for the account of the applicable L/C Issuer pursuant to Section 2.03(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03.

(iv) Until each Revolving Lender funds its Revolving Loan or L/C Advance pursuant to this Section 2.03(c) to reimburse the applicable L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Applicable Revolving Percentage of such amount shall be solely for the account of the applicable L/C Issuer.

(v) Each Revolving Lender’s obligation to make Revolving Loans or L/C Advances to reimburse each L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against any L/C Issuer, any Borrower, any Subsidiary or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default; (C) any existing Class of Revolving Commitments or (D) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Revolving Lender’s obligation to make Revolving Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other



than delivery by the Company of a Loan Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation of the applicable Borrower to reimburse the applicable L/C Issuer for the amount of any payment made by such L/C Issuer under any Letter of Credit, together with interest as provided herein.

(vi) If any Revolving Lender fails to make available to the Administrative Agent for the account of the applicable L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii), then, without limiting the other provisions of this Agreement, such L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such L/C Issuer at a rate per annum equal to the applicable Overnight Rate from time to time in effect, plus any administrative, processing or similar fees customarily charged by such L/C Issuer in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender's Revolving Loan included in the relevant Revolving Borrowing or L/C Advance in respect of the relevant L/C Borrowing, as the case may be. A certificate of any L/C Issuer submitted to any Revolving Lender (through the Administrative Agent) with respect to any amounts owing under this Section 2.03(c)(vi) shall be conclusive absent manifest error.

## (d) Repayment of Participations.

(i) At any time after any L/C Issuer has made a payment under any Letter of Credit and has received from any Revolving Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.03(c), if the Administrative Agent receives for the account of such L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the applicable Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Applicable Revolving Percentage thereof in Dollars and in the same funds as those received by the Administrative Agent.

(ii) If any payment received by the Administrative Agent for the account of the applicable L/C Issuer pursuant to Section 2.03(c)(i) is required to be returned under any of the circumstances described in Section 11.05 (including pursuant to any settlement entered into by such L/C Issuer in its discretion), each Revolving Lender shall pay to the Administrative Agent for the account of the applicable L/C Issuer its Applicable Revolving Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the applicable Overnight Rate from time to time in effect. The obligations of the



Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Obligations Absolute. The obligation of each applicable Borrower to reimburse each L/C Issuer for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other Loan Document;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that any Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), any L/C Issuer or any other Person, whether in connection with this Agreement or by such Letter of Credit, the transactions contemplated hereby or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, endorsement, certificate or other document presented under or in connection with such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) waiver by any L/C Issuer of any requirement that exists for such L/C Issuer’s protection and not the protection of any Borrower or any waiver by such L/C Issuer which does not in fact materially prejudice the Borrowers;

(v) honor of a demand for payment presented electronically even if such Letter of Credit requires that demand be in the form of a draft;

(vi) any payment made by any L/C Issuer in respect of an otherwise complying item presented after the date specified as the expiration date of, or the date by which documents must be received under, such Letter of Credit if presentation after such date is authorized by the UCC, the ISP or the UCP, as applicable;

(vii) any payment by any L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by such L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter



of Credit, including any arising in connection with any proceeding under any Debtor Relief Law;

(viii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Borrower or any of its Subsidiaries; or

(ix) any adverse change in the relevant exchange rates or in the availability of the relevant Alternative Currency to any Borrower or any Subsidiary or in the relevant currency markets generally;

provided that the foregoing shall not excuse any L/C Issuer from liability to the Borrowers to the extent provided in the second proviso to Section 2.03(f).

The applicable Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with any of such Borrower’s instructions or other irregularity, such Borrower will immediately notify the applicable L/C Issuer. The Borrowers shall be conclusively deemed to have waived any such claim against the applicable L/C Issuer and its correspondents unless such notice is given as aforesaid.

(1) Role of L/C Issuers. Each Lender and each Borrower agree that, in paying any drawing under a Letter of Credit, the applicable L/C Issuer shall not have any responsibility to obtain any document (other than any sight or time draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the L/C Issuers, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of any L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence, willful misconduct or bad faith; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. The Borrowers hereby assume all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrowers’ pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the L/C Issuers, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of any L/C Issuer shall be liable or responsible for any of the matters described in Section 2.03(e); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrowers may have a claim against any L/C Issuer, and such L/C Issuer may be liable to the Borrowers, to the extent, but only to the extent, of any direct, as opposed to consequential, special, indirect, punitive or exemplary, damages suffered by the Borrowers which the Borrowers prove, as determined by a final nonappealable



judgment of a court of competent jurisdiction, were caused by such L/C Issuer’s gross negligence, willful misconduct or bad faith or such L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight or time draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, any L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and no L/C Issuer shall be responsible for the validity or sufficiency of any instrument transferring, endorsing or assigning or purporting to transfer, endorse or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason. Any L/C Issuer may send a Letter of Credit or conduct any communication to or from the beneficiary via the Society for Worldwide Interbank Financial Telecommunication (“SWIFT”) message or overnight courier, or any other commercially reasonable means of communicating with a beneficiary.

(g) Applicability of ISP and UCP; Limitation of Liability. Unless otherwise expressly agreed by the applicable L/C Issuer and the applicable Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby Letter of Credit and (ii) the rules of the UCP shall apply to each commercial Letter of Credit. Notwithstanding the foregoing, no L/C Issuer shall be responsible to the Borrowers for, and no L/C Issuer’s rights and remedies against the Borrowers shall be impaired by, any action or inaction of such L/C Issuer required or permitted under any law, order, or practice that is required or permitted to be applied to any Letter of Credit or this Agreement, including the Law or any order of a jurisdiction where such L/C Issuer or the beneficiary is located, the practice stated in the ISP or UCP, as applicable, or in the decisions, opinions, practice statements, or official commentary of the ICC Banking Commission, the Bankers Association for Finance and Trade - International Financial Services Association (BAFT-IFSA), or the Institute of International Banking Law & Practice, whether or not any Letter of Credit chooses such law or practice.

(h) Letter of Credit Fees. The applicable Borrowers shall pay to the Administrative Agent for the account of each Revolving Lender in accordance, subject to Section 2.15, with its Applicable Revolving Percentage a Letter of Credit fee (the “Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Rate times the Dollar Equivalent of the daily amount available to be drawn under such Letter of Credit. Letter of Credit Fees shall be (1) due and payable on the first Business Day following each fiscal quarter end, commencing with the first such date to occur after the issuance of such Letter of Credit on the Letter of Credit Expiration Date and thereafter on demand and (2) computed on a quarterly basis in arrears.

(i) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuers. The applicable Borrowers shall pay directly to the applicable L/C Issuer for its own account a fronting fee (i) with respect to each commercial Letter of Credit, at a rate



per annum equal to 0.125% (or such other rate separately agreed between the applicable Borrowers and the L/C Issuers), computed on the Dollar Equivalent of the amount of such Letter of Credit, and payable upon the issuance thereof, (ii) with respect to any amendment of a commercial Letter of Credit increasing the amount of such Letter of Credit, at a rate separately agreed between the applicable Borrowers and such L/C Issuer, computed on the Dollar Equivalent of the amount of such increase, and payable upon the effectiveness of such amendment, and (iii) with respect to each standby Letter of Credit, at a rate per annum equal to 0.125% (or such other rate separately agreed between the applicable Borrowers and the L/C Issuers), computed on the Dollar Equivalent of the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears. Such fronting fee shall be due and payable on or prior to the date that is ten (10) Business Days following each fiscal quarter end, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.06. In addition, the applicable Borrowers shall pay directly to the applicable L/C Issuer for its own account, in Dollars, the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of such L/C Issuer relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

(i) Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control.

(k) L/C Issuer Reports to the Administrative Agent. Unless otherwise agreed by the Administrative Agent, each L/C Issuer shall, in addition to its notification obligations set forth elsewhere in this Section, provide the Administrative Agent a Letter of Credit Report, as set forth below:

(i) reasonably prior to the time that such L/C Issuer issues, amends, renews, increases or extends a Letter of Credit, the date of such issuance, amendment, renewal, increase or extension and the stated amount of the applicable Letters of Credit after giving effect to such issuance, amendment, renewal or extension (and whether the amounts thereof shall have changed);

(ii) on each Business Day on which such L/C Issuer makes a payment pursuant to a Letter of Credit, the date and amount of such payment;

(iii) on any Business Day on which any applicable Borrower fails to reimburse a payment made pursuant to a Letter of Credit required to be reimbursed to such L/C Issuer on such day, the date of such failure and the amount of such payment;



(iv) on any other Business Day, such other information as the Administrative Agent shall reasonably request as to the Letters of Credit issued by such L/C Issuer; and

(v) for so long as any Letter of Credit issued by an L/C Issuer is outstanding, such L/C Issuer shall deliver to the Administrative Agent (A) on the last Business Day of each calendar month, (B) at all other times a Letter of Credit Report is required to be delivered pursuant to this Agreement, and (C) on each date that (1) an L/C Credit Extension occurs or (2) there is any expiration, cancellation and/or disbursement, in each case, with respect to any such Letter of Credit, a Letter of Credit Report appropriately completed with the information for every outstanding Letter of Credit issued by such L/C Issuer.

(I) Additional L/C Issuers. Any Lender hereunder (that is reasonably acceptable to the Administrative Agent) may become an L/C Issuer upon receipt by the Administrative Agent of a fully executed Notice of Additional L/C Issuer which shall be signed by the Company, the Administrative Agent and each L/C Issuer.

(m) Letters of Credit Issued for Restricted Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Restricted Subsidiary of any Borrower, such Borrower shall be obligated to reimburse each L/C Issuer hereunder for any and all drawings under each Letter of Credit issued by such L/C Issuer. Each Borrower hereby acknowledges that the issuance of Letters of Credit for the account of its Restricted Subsidiaries inures to the benefit of such Borrower, and that such Borrower’s business derives substantial benefits from the businesses of such Restricted Subsidiaries.

## 2.04 Swingline Loans.

(a) The Swingline. Subject to the terms and conditions set forth herein, the Swingline Lender, in reliance upon the agreements of the other Lenders set forth in this Section, may in its sole discretion make loans to the Company (each such loan, a “Swingline Loan”). Each such Swingline Loan may be made, subject to the terms and conditions set forth herein, to the Company, in Dollars, from time to time on any Business Day during the Availability Period for any Class of Revolving Commitments in which the Swingline Lender holds a Revolving Commitment, in an aggregate amount not to exceed at any time outstanding the amount of the Swingline Sublimit, notwithstanding the fact that such Swingline Loans, when aggregated with the Applicable Revolving Percentage of the Outstanding Amount of Revolving Loans and L/C Obligations of the Lender acting as Swingline Lender, may exceed the amount of such Lender’s Revolving Commitment; provided, however, that (i) after giving effect to any Swingline Loan, (A) the Total Revolving Outstandings shall not exceed the Aggregate Revolving Commitments at such time, (B) the Revolving Exposure of any Revolving Lender at such time shall not exceed such Lender’s Revolving Commitment, and (C) the Revolving Exposure of any Lender under any Class of Revolving Commitments shall not exceed such Lender’s Revolving Commitment of such Class, (ii) the Company shall not use the



proceeds of any Swingline Loan to refinance any outstanding Swingline Loan, and (iii) the Swingline Lender shall not be under any obligation to make any Swingline Loan if it shall determine (which determination shall be conclusive and binding absent manifest error) that it has, or by such Credit Extension may have, Fronting Exposure. Within the foregoing limits, and subject to the other terms and conditions hereof, the Company may borrow under this Section, prepay under Section 2.05, and reborrow under this Section. Each Swingline Loan shall bear interest only at a rate based on the Base Rate plus the Applicable Rate. Immediately upon the making of a Swingline Loan, each Revolving Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan in an amount equal to the product of such Revolving Lender's Applicable Revolving Percentage (determined without regard to any separate Class or Classes of Revolving Commitments of such Lender) times the amount of such Swingline Loan.

## (b) Borrowing Procedures.

Subject to the terms and conditions hereof, each Swingline Borrowing shall be made upon the Company’s irrevocable notice to the Swingline Lender and the Administrative Agent, which may be given by: (i) telephone or (ii) a Swingline Loan Notice; provided that any telephonic notice must be confirmed immediately by delivery to the Swingline Lender and the Administrative Agent of a Swingline Loan Notice. Each such Swingline Loan Notice must be received by the Swingline Lender and the Administrative Agent not later than 1:00 p.m. on the requested borrowing date, and shall specify (A) the amount to be borrowed, which shall be a minimum of $100,000 and (B) the requested date of the Borrowing (which shall be a Business Day). Promptly after receipt by the Swingline Lender of any Swingline Loan Notice, the Swingline Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Swingline Loan Notice and, if not, the Swingline Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swingline Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the request of any Revolving Lender) prior to 2:00 p.m. on the date of the proposed Swingline Borrowing (1) directing the Swingline Lender not to make such Swingline Loan as a result of the limitations set forth in the first-proviso to the third-second sentence of Section 2.04(a), or (2) that one or more of the applicable conditions specified in Article IV is not then satisfied, then, subject to the terms and conditions hereof, the Swingline Lender may, make the amount of its Swingline Loan available to the Company at its office by crediting the account of the Company on the books of the Swingline Lender in Same Day Funds.

## (c) Refinancing of Swingline Loans.

(i) The Swingline Lender at any time in its sole discretion may request, on behalf of the Company (which hereby irrevocably authorizes the



Swingline Lender to so request on its behalf), that each Revolving Lender make a Base Rate Loan in an amount equal to such Lender’s Applicable Revolving Percentage (determined without regard to any Class or Classes of Revolving Commitments of such Lender) of the amount of Swingline Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Loan Notice for purposes hereof) and in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the Revolving Facility and the conditions set forth in Section 4.02. The Swingline Lender shall furnish the Company with a copy of the applicable Loan Notice promptly after delivering such notice to the Administrative Agent. Each Revolving Lender shall make an amount equal to its Applicable Revolving Percentage (determined without regard to any Class or Classes of Revolving Commitments of such Lender) of the amount specified in such Loan Notice available to the Administrative Agent in Same Day Funds (and the Administrative Agent may apply Cash Collateral available with respect to the applicable Swingline Loan) for the account of the Swingline Lender at the Administrative Agent’s Office for Dollar-denominated payments not later than 1:00 p.m. on the day specified in such Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Revolving Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Company in such amount. The Administrative Agent shall remit the funds so received to the Swingline Lender.

(ii) If for any reason any Swingline Loan cannot be refinanced by such a Revolving Borrowing in accordance with Section 2.04(c)(i), the request for Base Rate Loans submitted by the Swingline Lender as set forth herein shall be deemed to be a request by the Swingline Lender that each of the Revolving Lenders fund its risk participation in the relevant Swingline Loan and each Revolving Lender’s payment to the Administrative Agent for the account of the Swingline Lender pursuant to Section 2.04(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Revolving Lender fails to make available to the Administrative Agent for the account of the Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.04(c) by the time specified in Section 2.04(c)(i), the Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swingline Lender at a rate per annum equal to the applicable Overnight Rate from time to time in effect, plus any administrative, processing or similar fees customarily charged by the Swingline Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Loan included in the relevant Revolving Borrowing or funded participation in the relevant Swingline



Loan, as the case may be. A certificate of the Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Revolving Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swingline Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swingline Lender, any Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, (C) any Class of any such Loans or (D) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Revolving Lender’s obligation to make Revolving Loans pursuant to this Section 2.04(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the Company of a Loan Notice). No such funding of risk participations shall relieve or otherwise impair the obligation of the Company to repay Swingline Loans, together with interest as provided herein.

## (d) Repayment of Participations.

(i) At any time after any Revolving Lender has purchased and funded a risk participation in a Swingline Loan, if the Swingline Lender receives any payment on account of such Swingline Loan, the Swingline Lender will distribute to such Revolving Lender its Applicable Revolving Percentage (determined without regard to any separate Class or Classes of Revolving Commitments of such Lender) thereof in the same funds as those received by the Swingline Lender.

(ii) If any payment received by the Swingline Lender in respect of principal or interest on any Swingline Loan is required to be returned by the Swingline Lender under any of the circumstances described in Section 11.05 (including pursuant to any settlement entered into by the Swingline Lender in its discretion), each Revolving Lender shall pay to the Swingline Lender its Applicable Revolving Percentage (determined without regard to any separate Class or Classes of Revolving Commitments of such Lender) thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the applicable Overnight Rate. The Administrative Agent will make such demand upon the request of the Swingline Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Interest for Account of Swingline Lender. The Swingline Lender shall be responsible for invoicing the Company for interest on the Swingline Loans. Until each Revolving Lender funds its Base Rate Loan or risk participation pursuant to this Section to refinance such Revolving Lender’s Applicable Revolving Percentage of any Swingline



Loan, interest in respect of such Applicable Revolving Percentage shall be solely for the account of the Swingline Lender.

(f) Payments Directly to Swingline Lender. The Company shall make all payments of principal and interest in respect of the Swingline Loans directly to the Swingline Lender.

## 2.05 Prepayments.

## (a) Optional.

(i) The Borrowers may, upon notice to the Administrative Agent pursuant to delivery to the Administrative Agent of a Notice of Loan Prepayment, at any time or from time to time voluntarily prepay Revolving Loans in whole or in part without premium or penalty subject to Section 3.05; provided that, unless otherwise agreed by the Administrative Agent, (A) such notice must be received by the Administrative Agent not later than 11:00 a.m. (1) three (3) Business Days prior to any date of prepayment of Eurocurrency Rate Loans denominated in Dollars, Euro or Sterling, (2) four (4) Business Days (or five (5), in the case of prepayment of Loans denominated in Special Notice Currencies) prior to any date of prepayment of Eurocurrency Rate Loans denominated in other Alternative Currencies, and (3) on the date of prepayment of Base Rate Loans; (B) any prepayment of Eurocurrency Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (C) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date, the currency and amount of such prepayment and the Type(s) of Loans to be prepaid and, if Eurocurrency Rate Loans are to be prepaid, the Interest Period(s) of such Loans. The Administrative Agent will promptly notify each Appropriate Lender of its receipt of each such notice, and of the amount of such Lender's ratable portion of such prepayment (based on such Lender's Applicable Percentage). If such notice is given by any Borrower, the applicable Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein; provided, that any notice of prepayment may state that such notice is conditional upon the effectiveness of any facility or instrument refinancing all or a portion of the outstanding Revolving Commitments or upon the consummation of any other debt or equity transaction or event that will generate financing in connection therewith, in which case, such notice may be revoked by the applicable Borrower (by notice to the Administrative Agent on or prior to the specified date) if such condition is not satisfied. Any prepayment of principal shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05. Subject to Section 2.15, such prepayments shall be paid to the Lenders in accordance with their respective Applicable Percentages.



(ii) The Company may, upon notice to the Swingline Lender pursuant to delivery to the Swingline Lender of a Notice of Loan Prepayment (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swingline Loans in whole or in part without premium or penalty; provided that, unless otherwise agreed by the Swingline Lender, (A) such notice must be received by the Swingline Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and (B) any such prepayment shall be in a minimum principal amount of $100,000 or a whole multiple of $100,000 in excess hereof (or, if less, the entire principal thereof then outstanding). Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Company, the Company shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein; provided, that any notice of prepayment may state that such notice is conditional upon the effectiveness of any facility or instrument refinancing all or a portion of the outstanding Revolving Commitments or upon the consummation of any other debt or equity transaction or event that will generate financing in connection therewith, in which case, such notice may be revoked by the Company (by notice to the Administrative Agent on or prior to the specified date) if such condition is not satisfied. Any prepayment of principal shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05.

## (b) Mandatory.

(i) If for any reason the Total Revolving Outstandings at any time exceed the Aggregate Revolving Commitment then in effect for the Revolving Facility at such time, the applicable Borrowers shall promptly (and in any event, within one (1) Business Day) prepay Revolving Loans, Swingline Loans and L/C Borrowings (together with all accrued but unpaid interest thereon) and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided, however, that the Borrowers shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.05(b)(i) unless, after the prepayment of the Revolving Loans and Swingline Loans, the Total Revolving Outstandings exceed the Aggregate Revolving Commitment then in effect for the Revolving Facility at such time; provided further, that if any such excess shall result solely from a change in the applicable exchange rates relating to Alternative Currencies, then such prepayment and/or Cash Collateralization shall only be required to be made by the applicable Borrowers upon three (3) Business Days' notice from the Administrative Agent to the Company.

(ii) If the Administrative Agent notifies the Company at any time that, as a result of a change in the applicable exchange rates relating to Alternative Currencies, the Outstanding Amount of all L/C Obligations at such time exceeds an amount equal to 105% of the Letter of Credit Sublimit then in effect, then, within, three (3) Business Days after the Company’s receipt of such notice, the



applicable Borrowers shall Cash Collateralize Letters of Credit in an aggregate amount sufficient to reduce such Outstanding Amount as of such date of payment to an amount not to exceed 100% of the Letter of Credit Sublimit then in effect.

(iii) If the Administrative Agent notifies the Company at any time that, as a result of a change in the applicable exchange rates relating to Alternative Currencies, the Total Revolving Outstandings denominated in Alternative Currencies at such time exceeds an amount equal to 105% of the Alternative Currency Sublimit then in effect, then, within three (3) Business Days after the Company’s receipt of such notice, the applicable Borrowers shall prepay Revolving Loans and/or Cash Collateralize Letters of Credit, in each case denominated in Alternative Currencies, in an aggregate amount sufficient to reduce Total Revolving Outstandings denominated in Alternative Currencies as of such date of payment to an amount not to exceed 100% of the Alternative Currency Sublimit then in effect; provided, however, that the Borrowers shall not be required to Cash Collateralize such Letters of Credit pursuant to this Section 2.05(b)(iii) unless, after the prepayment of the Revolving Loans denominated in Alternative Currencies, the Total Revolving Outstandings denominated in Alternative Currencies exceed the Alternative Currency Sublimit then in effect.

(iv) Except as otherwise provided in Section 2.15, (A) prepayments of the Revolving Facility made pursuant to Section 2.05(b)(i) (other than by provision of Cash Collateral) first, shall be applied ratably to the L/C Borrowings and the Swingle Loans, and second, shall be applied to the outstanding Revolving Loans, ratably across each outstanding Class of Revolving Loans, and (B) prepayments of the Revolving Facility made pursuant to Section 2.05(b)(iii) (other than by provision of Cash Collateral) shall be applied to the outstanding Revolving Loans denominated in Alternative Currencies, ratably across each outstanding Class of Revolving Loans. Cash Collateral provided pursuant to this Section 2.05(b) shall be applied in accordance with Section 2.14. Upon the drawing of any Letter of Credit that has been Cash Collateralized, the funds held as Cash Collateral shall be applied (without any further action by or notice to or from any Loan Party or any Defaulting Lender that has provided Cash Collateral) to reimburse the applicable L/C Issuer or the Revolving Lenders, as applicable.

Within the parameters of the applications set forth above in Section 2.05(b), prepayments pursuant to Section 2.05(b) shall be applied first to Base Rate Loans and then to Eurocurrency Rate Loans in direct order of Interest Period maturities. All prepayments under Section 2.05(b) shall be subject to Section 3.05, but otherwise without premium or penalty, and shall be accompanied by interest on the principal amount prepaid through the date of prepayment.



Notwithstanding anything to the contrary in this Section 2.05, no prepayment by a Designated Foreign Borrower shall be used to pay or be applied against any Guaranteed Obligations of or attributable to any U.S. Loan Party (or any other Domestic Subsidiary).

## 2.06 Termination or Reduction of Commitments.

(a) Optional. The Company may, upon notice to the Administrative Agent, terminate the Revolving Facility, the Letter of Credit Sublimit, the Swingline Sublimit or the Alternative Currency Sublimit, or from time to time permanently reduce the Revolving Facility, the Letter of Credit Sublimit, the Swingline Sublimit or the alternative Currency Sublimit; provided that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m. three (3) Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of $500,000 in excess thereof and (iii) the Company shall not terminate or reduce (A) the Revolving Facility if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Revolving Outstandings would exceed the Aggregate Revolving Commitments, (B) the Letter of Credit Sublimit if, after giving effect thereto, the Outstanding Amount of L/C Obligations not fully Cash Collateralized hereunder would exceed the Letter of Credit Sublimit, (C) the Swingline Sublimit if, after giving effect thereto and to any concurrent prepayments hereunder, the Outstanding Amount of Swingline Loans would exceed the Swingline Sublimit, or (D) the Alternative Currency Sublimit if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Revolving Outstandings denominated in Alternative Currencies would exceed the Alternative Currency Sublimit; and provided, further, that any notice of permanent reduction or termination may state that such notice is conditional upon the effectiveness of any facility or instrument refinancing all or a portion of the outstanding Revolving Commitments or upon the consummation of any other debt or equity transaction or event that will generate financing in connection therewith, in which case such notice may be revoked by the Company (by notice to the Administrative Agent on or prior to the specified date) if such condition is not satisfied.

(b) Mandatory. If after giving effect to any reduction or termination of Revolving Commitments under this Section 2.06, the Letter of Credit Sublimit, the Alternative Currency Sublimit or the Swingline Sublimit exceeds the Aggregate Revolving Commitments at such time, the Letter of Credit Sublimit, the Alternative Currency Sublimit or the Swingline Sublimit, as the case may be, shall be automatically reduced by the amount of such excess.

(c) Application of Commitment Reductions; Payment of Fees. The Administrative Agent will promptly notify the Lenders of any termination or reduction of the Letter of Credit Sublimit, the Alternative Currency Sublimit, the Swingline Sublimit or the Revolving Commitment under this Section 2.06. Upon any reduction of the Revolving Commitments, the Revolving Commitment of each Revolving Lender shall be reduced on a pro rata basis across all Classes of Revolving Commitments by such Lender’s Applicable Revolving Percentage of such reduction amount. All fees in respect



of the Revolving Facility accrued until the effective date of any termination of the Revolving Facility shall be paid on the effective date of such termination.

## 2.07 Repayment of Loans.

(a) Revolving Loans. The applicable Borrowers shall repay to the relevant Revolving Lenders on the applicable Maturity Date for each Class of Revolving Loans the aggregate principal amount of all Revolving Loans of such Class outstanding on such date made to such Borrower (it being understood and agreed that, subject to the other terms and conditions hereof, the Borrowers may make Borrowings of Revolving Loans under any remaining Revolving Commitments of any other Class to effect such repayment).

(b) Swingline Loans. The Company shall repay each Swingline Loan on the earlier to occur of (i) the date ten (10) Business Days after such Loan is made (it being understood that the Company may use the proceeds of a Borrowing of Revolving Loans for such repayment, subject to the applicable conditions to such Borrowing hereunder) and (ii) the latest Latest Maturity Date for any Class of Revolving Commitments maintained by the Swingline Lender (in its capacity as a Revolving Lender).

(c) Reallocation of Applicable Percentages after Maturity. Upon the occurrence of a Maturity Date for any applicable Class of Revolving Loans, the relevant Applicable Percentages with respect to each remaining Class of Revolving Commitments shall be readjusted without any further action or consent of any other party (calculated without regard to the Class of Revolving Commitments as to which the Maturity Date has occurred), to reflect the expiration of the Class of Revolving Commitments as to which the Maturity Date has occurred.

## 2.08 Interest and Default Rate.

(a) Interest. Subject to the provisions of Section 2.08(b), (i) each Eurocurrency Rate Loan under the Revolving Facility shall bear interest on the outstanding principal amount thereof for each Interest Period from the applicable borrowing date at a rate per annum equal to the Eurocurrency Rate for such Interest Period plus the Applicable Rate; (ii) each Base Rate Loan under the Revolving Facility shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate; and (iii) each Swingline Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate. To the extent that any calculation of interest or any fee required to be paid under this Agreement shall be based on (or result in) a calculation that is less than zero, such calculation shall be deemed zero for purposes of this Agreement.



## (b) Default Rate.

(i) Upon the occurrence of any Event of Default under Section 8.01(a), whether at stated maturity, by acceleration or otherwise, all outstanding Obligations (including Letter of Credit Fees) shall accrue at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(ii) Upon the occurrence of any Event of Default under Section 8.01(f) or Section 8.01(g), all outstanding Obligations (including Letter of Credit Fees) shall accrue at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iii) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c) Interest Payments. Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

## 2.09 Fees.

In addition to certain fees described in subsections (h) and (i) of Section 2.03:

(a) Commitment Fee. The Company shall pay to the Administrative Agent for the account of each Revolving Lender in accordance with its Applicable Revolving Percentage, a commitment fee in Dollars equal to the Applicable Rate times the actual daily amount by which the Revolving Facility exceeds the sum of (i) the Outstanding Amount of Revolving Loans and (ii) the Outstanding Amount of L/C Obligations, subject to adjustment as provided in Section 2.15. For the avoidance of doubt, the Outstanding Amount of Swinglein Loans shall not be counted towards or considered usage of the Revolving Facility for purposes of determining the commitment fee. The commitment fee shall be calculated quarterly in arrears and shall accrue at all times during the Availability Period, including at any time during which one or more of the conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the third Business Day after the end of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the last day of the Availability Period for the Revolving Facility. For purposes of calculating the commitment fee, if there is any change in the Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

## (b) Other Fees.



(i) The applicable Borrowers shall pay to the Persons entitled thereto, for their own account, in Dollars, fees in the amounts and at the times specified in the Fee Letter. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

(ii) The applicable Borrowers shall pay to the Lenders and the Arrangers, such fees as shall have been separately agreed upon in writing and disclosed to the Administrative Agent in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

## 2.10 Computation of Interest and Fees; Retroactive Adjustments of Applicable Rate.

(a) Computation of Interest and Fees. All computations of interest for Base Rate Loans (including Base Rate Loans determined by reference to the Eurocurrency Rate) shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year), or, in the case of interest in respect of Loans denominated in Alternative Currencies as to which market practice differs from the foregoing, in accordance with such market practice. Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.12(a), bear interest for one (1) day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error. With respect to all Non-LIBOR Quoted Currencies, the calculation of the applicable interest rate shall be determined in accordance with market practice.

(b) Financial Statement Adjustments or Restatements. If, as a result of any restatement of or other adjustment to the financial statements of the Company and its Subsidiaries or for any other reason, the Company, or the Lenders determine that (i) the Consolidated Leverage Ratio as calculated by the Company as of any applicable date was inaccurate and (ii) a proper calculation of the Consolidated Leverage Ratio would have resulted in higher pricing for such period, the Borrowers shall retroactively be obligated to pay to the Administrative Agent for the account of the applicable Lenders or the applicable L/C Issuers, as the case may be, promptly on demand by the Administrative Agent (or, after the occurrence of an actual or deemed entry of an order for relief with respect to any Borrower under the Bankruptcy Code of the United States, automatically and without further action by the Administrative Agent, any Lender or any L/C Issuer), an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period. This paragraph shall not limit the rights of the Administrative Agent, any Lender or any L/C Issuer, as the case may be, under any provision of this Agreement to payment of any



Obligations hereunder at the Default Rate or under Article VIII. The Borrowers’ obligations under this paragraph shall survive the termination of the Aggregate Revolving Commitments and the repayment of all other Obligations hereunder. Any additional interest or fees under this Section 2.10(b) shall not be due and payable until a demand is made for such payment by the Administrative Agent and accordingly, any nonpayment of such interest or fees as a result of any such inaccuracy shall not constitute a Default (whether retroactively or otherwise), and none of such additional amounts shall be deemed overdue or accrue interest at the Default Rate.

## 2.11 Evidence of Debt.

(a) Maintenance of Accounts. The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrowers and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrowers shall execute and deliver to such Lender (through the Administrative Agent) a Revolving Note, which shall evidence such Lender's Loans in addition to such accounts or records. Each Lender may attach schedules to its Revolving Note and endorse thereon the date, Type (if applicable), amount, currency and maturity of its Loans and payments with respect thereto.

(b) Maintenance of Records. In addition to the accounts and records referred to in Section 2.11(a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

## 2.12 Payments Generally; Administrative Agent’s Clawback.

(a) General. All payments to be made by the Borrowers shall be made free and clear of and without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein and except with respect to principal of and interest on Loans denominated in an Alternative Currency, all payments by the Borrowers hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the applicable Administrative Agent’s Office in Dollars and in Same Day Funds not later than 2:00 p.m.



on the date specified herein. Except as otherwise expressly provided herein, all payments by the Borrowers hereunder with respect to principal and interest on Loans denominated in an Alternative Currency shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the applicable Administrative Agent's Office in such Alternative Currency and in Same Day Funds not later than the Applicable Time specified by the Administrative Agent on the dates specified herein. Without limiting the generality of the foregoing, the Administrative Agent may require that any payments due under this Agreement be made in the United States. If, for any reason, any Borrower is prohibited by any Law from making any required payment hereunder in an Alternative Currency, such Borrower shall make such payment in Dollars in the Dollar Equivalent of the Alternative Currency payment amount. The Administrative Agent will promptly distribute to each Appropriate Lender its relevant Applicable Percentage (or other applicable share (including on account of Extended Revolving Commitments) as provided herein) of such payment in like funds as received by wire transfer to such Lender's Lending Office. All payments received by the Administrative Agent (i) after 2:00 p.m., in the case of payments in Dollars or (ii) after the Applicable Time specified by the Administrative Agent, in the case of payments in an Alternative Currency, shall in each case be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. Subject to Section 2.07(a) and as otherwise specifically provided for in this Agreement, if any payment to be made by a Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurocurrency Rate Loans (or, in the case of any Borrowing of Base Rate Loans, prior to 12:00 noon on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of Base Rate Loans, that such Lender has made such share available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the applicable Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in Same Day Funds with interest thereon, for each day from and including the date such amount is made available to the applicable Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the Overnight Rate, plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing and (B) in the case of a payment to be made by any Borrower, the interest rate applicable to Base Rate Loans or in the case of Alternative Currencies in accordance with such market practice, in each case as applicable. If the applicable



Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the applicable Borrower the amount of such interest paid by the applicable Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender's Loan included in such Borrowing. Any payment by the applicable Borrower shall be without prejudice to any claim the applicable Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(ii) Payments by Borrowers; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Company prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the L/C Issuers hereunder that the applicable Borrower will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Appropriate Lenders or the applicable L/C Issuers, as the case may be, the amount due. In such event, if any applicable Borrower has not in fact made such payment, then each of the Appropriate Lenders or the applicable L/C Issuers, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such L/C Issuer, in Same Day Funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Overnight Rate.

A notice of the Administrative Agent to any Lender or the Company with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

(c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made available to the Borrowers by the Administrative Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Revolving Loans, to fund participations in Letters of Credit and Swingline Loans and to make payments pursuant to Section 11.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 11.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 11.04(c).



(e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

(f) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Borrowing (other than Swingline Borrowings) shall be made from the Appropriate Lenders, each payment of fees under Sections 2.09(a) and 2.03(h) and shall be made for account of the Appropriate Lenders, and each termination or reduction of the amount of the Revolving Commitments shall be applied to the respective Revolving Commitments of the Lenders, pro rata according to the amounts of their respective Revolving Commitments; (ii) each Borrowing shall be allocated pro rata among the Lenders according to the amounts of their respective Revolving Commitments (in the case of the making of Revolving Loans) or their respective Loans that are to be included in such Borrowing (in the case of conversions and continuations of Loans); (iii) each payment or prepayment of principal of Loans by the Borrowers shall be made for account of the Appropriate Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by them; and (iv) each payment of interest on Loans by the Borrowers shall be made for account of the Appropriate Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Appropriate Lenders.

## 2.13 Sharing of Payments by Lenders.

If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of (a) Obligations in respect of the Revolving Facility due and payable to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender at such time to (ii) the aggregate amount of the Obligations in respect of the Revolving Facility due and payable to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations in respect of the Revolving Facility due and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by all the Lenders at such time or (b) Obligations in respect of any of the Revolving Facility owing (but not due and payable) to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing (but not due and payable) to such Lender at such time to (ii) the aggregate amount of the Obligations in respect of the Revolving Facility owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations in respect of the Revolving Facility owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the Lenders at such time, then, in each case under clauses (a) and (b) above, the Lender receiving such greater proportion shall (A) notify the Administrative Agent of such fact, and (B) purchase (for cash at face value) participations in the Loans and subparticipations in L/C Obligations and Swingline Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with



the aggregate amount of Obligations in respect of the Revolving Facility then due and payable to the Lenders or owing (but not due and payable) to the Lenders, as the case may be, provided that:

(1) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(2) the provisions of this Section shall not be construed to apply to (x) any payment made by or on behalf of the Borrowers pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender or Extended Revolving Commitments), (y) the application of Cash Collateral provided for in Section 2.14, or (z) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or subparticipations in L/C Obligations or Swingline Loans to any assignee or participant, other than an assignment to any Loan Party or any Affiliate thereof (as to which the provisions of this Section shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of such participation.

## 2.14 Cash Collateral.

(a) Certain Credit Support Events. If (i) any L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, (ii) as of the Letter of Credit Expiration Date, any L/C Obligation for any reason remains outstanding, (iii) any Borrower shall be required to provide Cash Collateral pursuant to Section 2.05 or 8.02(c) or (iv) there shall exist a Defaulting Lender, the applicable Borrowers shall, solely with respect to their respective outstanding Letters of Credit or L/C Borrowings, as applicable, immediately (in the case of clause (iii) above, except to the extent a longer period is provided under Section 2.05, as applicable) or within one (1) Business Day (in all other cases) following any request by the Administrative Agent or any L/C Issuer, provide Cash Collateral in an amount not less than the applicable Minimum Collateral Amount (determined in the case of Cash Collateral provided pursuant to clause (iv) above, after giving effect to Section 2.15(a)(iv) and any Cash Collateral provided by such Defaulting Lender) or the amount required pursuant to Section 2.05, as applicable.

(b) Grant of Security Interest. Each Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the L/C Issuers and the Lenders, and agrees to maintain, a first priority security interest in all such



cash, deposit accounts and all balances therein, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.14(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent or the L/C Issuers as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the applicable Borrower or, to the extent provided by any Defaulting Lender, such Defaulting Lender, will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in one or more blocked, interest bearing deposit accounts at Bank of America (it being understood and agreed that Bank of America and the Administrative Agent make no warranty or guarantee as to the level of, or amount (if any) of, interest with respect to such deposit account). The applicable Borrowers shall pay on demand therefor from time to time all customary account opening, activity and other administrative fees and charges in connection with the maintenance and disbursement of Cash Collateral. Each Designated Foreign Borrower hereby agrees to take all such further acts and to execute, acknowledge, deliver, record, file and register such documents and instruments as the Administrative Agent may reasonably require to carry out the provisions of this Section 2.14.

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 2.14 or Sections 2.03, 2.05, 2.15 or 8.02 in respect of Letters of Credit shall be held and applied to the satisfaction of the specific L/C Obligations, obligations to fund participations therein (including, as to Cash Collateral provided by a Revolving Lender that is a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein; provided that no Cash Collateral provided in respect of any Obligations of a Designated Foreign Borrower shall be applied to the satisfaction of any Obligations of or attributable to any U.S. Loan Party; provided further, however, that the Borrowers shall cause Cash Collateral to be provided by each applicable Borrower in an amount sufficient to Cash Collateralize the L/C Obligations related to such Borrower, as provided herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or to secure other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Revolving Lender (or, as appropriate, its assignee following compliance with Section 11.06(b)(vi))) or (ii) the determination by the Administrative Agent and the applicable L/C Issuer that there exists excess Cash Collateral; provided, however, (A) any such release shall be without prejudice to, and any disbursement or other transfer of Cash Collateral shall be and remain subject to, any other Lien conferred under the Loan Documents and the other applicable provisions of the Loan Documents, and (B) the



Person providing Cash Collateral and the applicable L/C Issuer may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

(e) Release of Lenders’ Obligations. Notwithstanding anything to the contrary contained herein or in any other Loan Document, in the event that (i) any applicable L/C Issuer shall have issued, in accordance with Section 2.03(a)(ii)(B), a Letter of Credit with an expiry date occurring after the Letter of Credit Expiration Date and (ii) the Borrowers shall have Cash Collateralized the Outstanding Amount of all such L/C Obligations in respect of such Letter of Credit pursuant to Section 2.14(a) above, then, upon the provision of such Cash Collateral and without any further action, each Lender hereunder shall be automatically released from any further obligation to such L/C Issuer in respect of such Letter of Credit, including, without limitation, any obligation of any such Lender to reimburse such L/C Issuer for amounts drawn under such Letter of Credit or to purchase any risk participation therein; provided, however, that all such obligations of each Lender hereunder to such L/C Issuer in respect of such Letter of Credit shall be revived if any Cash Collateral provided by the Borrowers in respect of such Letter of Credit is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or such L/C Issuer) to be repaid to a trustee, receiver, examiner or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such Cash Collateral had not been provided. The obligations of the Lenders under this paragraph shall survive the Facility Termination Date.

## 2.15 Defaulting Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law:

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of “Required Lenders” and Section 11.01.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 11.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any L/C Issuer or Swingline Lender hereunder; third, to Cash Collateralize each L/C Issuer’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.14; fourth, as the



Company may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Company, to be held in a deposit account and released pro rata in order to (A) satisfy such Defaulting Lender's potential future funding obligations with respect to Loans under this Agreement and (B) Cash Collateralize each L/C Issuer's future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.14; sixth, to the payment of any amounts owing to the Lenders, the L/C Issuers or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any L/C Issuer or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrowers as a result of any judgment of a court of competent jurisdiction obtained by the Borrowers against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise as may be required under the Loan Documents in connection with any Lien conferred thereunder or directed by a court of competent jurisdiction; provided that if (1) such payment is a payment of the principal amount of any Loans or L/C Borrowings in respect of which such Defaulting Lender has not fully funded its appropriate share, and (2) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 4.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Obligations owed to, all Non-Defaulting Lenders on a pro rata basis with respect to any applicable Class prior to being applied to the payment of any Loans of, or L/C Obligations owed to, such Defaulting Lender until such time as all Classes of the relevant Classes of Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro rata in accordance with the Revolving Commitments (including any applicable Class of Revolving Commitments) hereunder without giving effect to Section 2.15(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.15(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

## (iii) Certain Fees.

(A) Fees. No Defaulting Lender shall be entitled to receive any fee payable under Section 2.09(a) for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any



such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Letter of Credit Fees. Each Defaulting Lender shall be entitled to receive Letter of Credit Fees for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Revolving Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.14.

(C) Defaulting Lender Fees. With respect to any fee payable under Section 2.09(a) or any Letter of Credit Fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrowers shall (1) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender's participation in L/C Obligations or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2) pay to each L/C Issuer and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such L/C Issuer's or Swingline Lender's Fronting Exposure to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Applicable Revolving Percentages to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Revolving Percentages (calculated without regard to such Defaulting Lender’s Revolving Commitment) but only to the extent that (x) such reallocation does not cause the aggregate Revolving Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Revolving Commitment or the aggregate Revolving Exposure of any Non-Defaulting Lender under any Class of Revolving Commitments to exceed such Non-Defaulting Lender’s Revolving Commitment of such Class and (y) no Non-Defaulting Lender is allocated any Class of Revolving Commitments which it does not maintain. Subject to Section 11.20, no reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (a)(iv) above cannot, or can only partially, be effected, the applicable Borrowers shall, without prejudice to any right or remedy available to it hereunder or under applicable Law, (A) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s Fronting Exposure and



(B) second, Cash Collateralize each L/C Issuer’s Fronting Exposure in accordance with the procedures set forth in Section 2.14.

(b) Defaulting Lender Cure. If the Company, the Administrative Agent, Swingline Lender and the L/C Issuers agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 2.15(a) (iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

## 2.16 Designated Foreign Borrowers.

(a) Initial Designated Foreign Borrowers. Effective as of the date hereof, Vertex Europe and Vertex Ireland shall each be a “Designated Foreign Borrower” hereunder and may receive Loans and have Letters of Credit issued for its account as a Designated Foreign Borrower on the terms and conditions set forth in this Agreement.

(b) Additional Designated Foreign Borrowers. The Company may at any time, upon not less than fifteen (15) Business Days' notice from the Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), request to designate any additional Restricted Subsidiary that is a Foreign Subsidiary of the Company (an “Applicant Foreign Borrower”) as a Designated Foreign Borrower to receive Revolving Loans hereunder by delivering to the Administrative Agent (which shall promptly deliver counterparts thereof to each Lender) a duly executed Designated Foreign Borrower Request and Assumption Agreement. The parties hereto acknowledge and agree that prior to any Applicant Foreign Borrower becoming entitled to utilize the credit facilities provided for herein, (i) the Administrative Agent, the Lenders and the L/C Issuers must each agree to such Applicant Foreign Borrower becoming a Designated Foreign Borrower (such consent not to be unreasonably withheld or delayed) and (ii) the Administrative Agent, the Lenders and the L/C Issuers shall have received such supporting resolutions, incumbency certificates, opinions of counsel and other documents or information reasonably requested (including, without limitation and to the extent so requested, (x) to the extent any Applicant Foreign Borrower qualifies as a “legal entity customer” under the Beneficial Ownership



Regulation, a Beneficial Ownership Certification and (y) any other documentation and information regarding such Applicant Foreign Borrower reasonably requested by the Administrative Agent and the Lenders in order to comply with “know your customer” and anti-money laundering rules and regulations), in form, content and scope reasonably satisfactory to the Administrative Agent, as may be required by the Administrative Agent, and Revolving Notes signed by such new Borrowers to the extent any Lender so requires (the requirements in the foregoing clauses (i) and (ii), the “Designated Foreign Borrower Requirements”). If the Designated Foreign Borrower Requirements are met, the Administrative Agent shall send a Designated Foreign Borrower Notice to the Company, the Lenders and the L/C Issuers specifying the effective date upon which such Applicant Foreign Borrower shall constitute a Designated Foreign Borrower for purposes hereof, whereupon each of the Lenders and L/C Issuers agrees to permit such Designated Foreign Borrower to receive Credit Extensions hereunder, on the terms and conditions set forth herein, and each of the parties agrees that such Designated Foreign Borrower otherwise shall be a Borrower for all purposes of this Agreement; provided that no Loan Notice or Letter of Credit Application may be submitted by or on behalf of such Designated Foreign Borrower until the date that is five (5) Business Days after such effective date.

(c) Obligations. Except as specifically provided herein, the Obligations of each of the Borrowers (including, without limitation, Obligations under Sections 2.07, 2.08 and 2.09) shall be joint and several in nature, regardless of which Person actually receives Credit Extensions hereunder or the amount of such Credit Extensions received or the manner in which the Administrative Agent, the L/C Issuer or any Lender accounts for such Credit Extensions on its books and records; provided, however, that notwithstanding anything contained to the contrary herein or in any other Loan Document, the Designated Foreign Borrowers shall not be liable with respect to any Obligations of the Company.

(d) Appointment. Each Restricted Subsidiary of the Company that is or becomes a Designated Foreign Borrower hereby irrevocably appoints, designates and authorizes the Company to act on its behalf as its agent for all purposes of this Agreement and the other Loan Documents and authorizes the Company to take such actions on its behalf and to exercise such powers as are delegated to the Company by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Each Restricted Subsidiary of the Company that is or becomes a Designated Foreign Borrower hereby further agrees that (i) the Company may execute such documents on behalf of such Designated Foreign Borrower as the Company deems appropriate in its sole discretion and each Designated Foreign Borrower shall be obligated by all of the terms of any such document executed on its behalf, (ii) any notice or communication delivered by the Administrative Agent or the Lender to the Company shall be deemed delivered to each Designated Foreign Borrower and (iii) the Administrative Agent or the Lenders may accept, and be permitted to rely on, any document, instrument or agreement executed by the Company on behalf of each of the Loan Parties.



(e) Termination. The Company may from time to time, upon not less than three (3) Business Days' prior written notice from the Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), terminate a Designated Foreign Borrower's status as such; provided that (i) there are no outstanding Loans payable by such Designated Foreign Borrower, Letters of Credit issued for the account of such Designated Foreign Borrower or any of its Subsidiaries, or other amounts due and payable by such Designated Foreign Borrower as of the effective date of such termination, (ii) no Event of Default has occurred and is continuing or would result therefrom and (iii) immediately after giving effect to such termination, the aggregate outstanding principal amount of all Priority Indebtedness shall not exceed fifteen percent (15%) of Consolidated Net Worth (determined as of the last day of the most recent fiscal quarter for which financial statements shall have been delivered pursuant to Section 6.01(a) or 6.01(b) (or, prior to the delivery of any such financial statements, determined as of June 30, 2019)); provided further, that the Administrative Agent, the applicable L/C Issuer and the Lenders shall cooperate with any Designated Foreign Borrower to amend or replace any Letter of Credit in order to name the Company as the applicant or account party with respect to any Letter of Credit issued for the account of such Designated Foreign Borrower or any of its Subsidiaries. The Administrative Agent will promptly notify the Lenders of any such termination of a Designated Foreign Borrower's status.

## 2.17 Designated Lenders.

Each of the Administrative Agent, each L/C Issuer, each Swingle Lender and each Lender at its option may make any Credit Extension or otherwise perform its obligations hereunder through any Lending Office (each, a “Designated Lender”); provided that any exercise of such option shall not affect the obligation of any Borrower to repay any Credit Extension in accordance with the terms of this Agreement. Any Designated Lender shall be considered a Lender; provided that designation of a Designated Lender is for administrative convenience only and does not expand the scope of liabilities or obligations of any Lender or Designated Lender beyond those of the Lender designating such Person as a Designated Lender as provided in this Agreement.

## 2.18 Increase in Revolving Commitments.

## (a) Increase in Revolving Facility.

(i) Upon notice to the Administrative Agent (which shall promptly notify the Revolving Lenders), the Company may from time to time after the Closing Date, request an increase in the Revolving Facility by an aggregate amount (for all such requests) not to exceed $500,000,000 (any such increase in the Revolving Facility, an “Incremental Revolving Facility”); provided that (i) any such request for an Incremental Revolving Facility shall be in a minimum amount of $25,000,000, and in increments of $5,000,000 in excess thereof, or, if less, the entire remaining amount available for such Incremental Revolving Facility, and (ii) in no event shall the Aggregate Revolving Commitments under



the Revolving Facility (after giving effect to all requested increases therein) exceed $1,000,000,000. Subject to the terms and conditions hereof, the Company may seek commitments from existing Lenders or any other Person that is an Eligible Assignee who shall become a Revolving Lender in connection therewith. At the time of sending such notice, the Company (in consultation with the Administrative Agent) shall specify the time period within which each Revolving Lender is requested to respond (which shall in no event be less than ten (10) Business Days from the date of delivery of such notice to the Revolving Lenders).

(ii) Revolving Lender Elections to Increase. Each Revolving Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its Revolving Commitment and, if so, whether by an amount equal to, greater than, or less than its Applicable Percentage of such requested increase. Any Revolving Lender not responding within such time period shall be deemed to have declined to increase its Revolving Commitment.

(iii) Notification by Administrative Agent; Additional Revolving Lenders. The Administrative Agent shall notify the Company and each Revolving Lender of the Revolving Lenders' responses to each request made hereunder. To achieve the full amount of a requested increase (to the extent the existing Revolving Lenders do not agree to provide the entire amount of the requested increase), and subject to the approval of the Administrative Agent, the L/C Issuers and the Swingle Lender, the Company may also invite additional Eligible Assignees to become Revolving Lenders (together with any existing Revolving Lender participating in such increase, each, an "Increasing Revolving Lender") pursuant to a joinder agreement in form and substance reasonably satisfactory to the Administrative Agent and its counsel. Nothing contained herein shall constitute, or otherwise be deemed to be, a commitment on the part of any Revolving Lender to participate in any increase in the Revolving Facility.

(iv) Effective Date and Allocations. If the Revolving Facility is increased in accordance with this Section, the Administrative Agent and the Company shall determine (x) the effective date of any such increase (the "Revolving Facility Increase Effective Date") and (y) the final allocation of such increase among the Increasing Revolving Lenders and Schedule 1.01(b) attached hereto shall be automatically updated to reflect the same. The Administrative Agent shall promptly notify the Company and the Revolving Lenders of the final allocation of such increase and the Revolving Facility Increase Effective Date.

(b) Conditions to Effectiveness of Increase. As a condition precedent to each such increase in the Revolving Facility pursuant to this Section 2.18:

(i) as of the Revolving Facility Increase Effective Date, before and after giving effect to such increase, (A) no Default or Event of Default shall then exist or would exist after giving effect thereto exists, (B) the Company shall demonstrate to the reasonable satisfaction of the Administrative Agent that, after



giving effect to such increase on a Pro Forma Basis (as if the entire amount of the Incremental Revolving Facility has been fully-funded), the Company is in Pro Forma Compliance, and (C) the representations and warranties contained in Article V and each other Loan Documents shall be true and correct in all material respects (or in the case of a representation or warranty that is already subject to a materiality condition, in all respects), except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct as of such earlier date, and except that for purposes of this Section 2.18, the representations and warranties contained in clauses (a) and (b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01.

(ii) the Company shall have delivered to the Administrative Agent a certificate of each Loan Party dated as of the Revolving Facility Increase Effective Date, signed by a Responsible Officer of such Loan Party (x) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (y) certifying (and attaching calculations, as appropriate, in reasonable detail necessary to demonstrate) that, before and after giving effect to such increase each, of the conditions set forth in clause (i) above are satisfied; and

(iii) the Company shall have delivered, or cause to be delivered, customary legal opinions, officers' certificates, reaffirmation agreements and other documents consistent in all material respects with those delivered on the Closing Date under Section 4.01 with respect to the Company, the other Borrowers and all applicable Subsidiary Guarantors (other than changes to such legal opinions resulting from a change in Law, change in fact or change to counsel's form of opinion reasonably satisfactory to the Administrative Agent) as reasonably requested by the Administrative Agent in connection with each such increase in the Revolving Facility.

The applicable Borrowers shall prepay any Revolving Loans outstanding on the Revolving Facility Increase Effective Date (and pay any additional amounts required pursuant to Section 3.05) to the extent necessary to keep the outstanding Revolving Loans ratable with any revised Applicable Revolving Percentages arising from any nonratable increase in the Revolving Commitments under this Section 2.18.

(c) Terms of Increase. Any increase in the Revolving Facility shall be made on the same terms (including, without limitation, interest, payment, amortization and maturity terms), and shall be subject to the same conditions as existing Revolving Commitments (or, if more than one Class of Revolving Commitments is then outstanding, the Revolving Commitments with the then Latest Maturity Date) except customary arrangement or commitment fees payable to the Arrangers or one or more Increasing Revolving Lenders may be different from those paid with respect to the existing Revolving Commitments of the existing Lenders on or prior to the Closing Date



or with respect to any other Increasing Revolving Lender in connection with any other increase in the Revolving Facility pursuant to this Section 2.18.

(d) Conflicting Provisions. This Section 2.18 shall supersede any provisions in Section 2.13 or 11.01 to the contrary.

## 2.19 Extension of Maturity Date.

(a) Request for Extended Revolving Commitments. So long as no Event of Default has occurred and is continuing, the Borrowers may at any time and from time to time, upon written request to and the consent of the Administrative Agent, the Swingline Lender and the L/C Issuers, request (each, a “Revolving Extension Request”) that an aggregate principal amount of not less than $100,000,000 of the then existing Revolving Commitments of any Class (each, an “Existing Revolving Tranche”) be amended to, among other things, extend the applicable Maturity Date with respect thereto (the “Existing Maturity Date”) to a date that is no earlier than the then Latest Maturity Date of any other Revolving Commitment hereunder (any such Revolving Commitments so amended, “Extended Revolving Commitments”); provided that (i) after giving effect to any Extended Revolving Commitments under this Section 2.19, there shall be no more than three (3) Classes of Revolving Commitments outstanding at any time and (ii) any such Extended Revolving Commitments shall be offered on the same terms to each Revolving Lender under the applicable Existing Revolving Tranche on a ratable basis. For the avoidance of doubt, the reference to “on the same terms” in the preceding sentence shall mean that all of the Revolving Lenders holding such Existing Revolving Tranche are offered to be extended for the same amount of time, offered the same type of Revolving Commitment and that the interest rate changes and fees payable with respect to such extension are the same. Promptly after receipt of any Revolving Extension Request, the Administrative Agent shall provide a copy of such request to each of the Revolving Lenders under the applicable Existing Revolving Tranche to be amended, which request shall set forth the proposed terms (which shall be determined in consultation with the Administrative Agent) of the Extended Revolving Commitments to be established. Each Revolving Extension Request shall specify (A) the applicable Class of Revolving Commitments and Revolving Loans hereunder to be extended, (B) the date to which the applicable Maturity Date is sought to be extended, and (C) the changes, if any, to the Applicable Rate to be applied in determining the interest payable on the Revolving Loans of, and fees payable hereunder to, Extending Revolving Lenders in respect of that portion of their Revolving Commitments and Revolving Loans extended to such new Maturity Date; provided, however, that such Extended Revolving Commitments shall, except as to interest rates, fees and any other pricing terms and final maturity, have the same terms (including borrowing terms and payment terms (other than payment on the applicable Maturity Date)) as the existing Class of Revolving Commitments from which they are extended. At the time of sending such notice, the Company (in consultation with the Administrative Agent) shall specify the time period within which each applicable Revolving Lender is requested to respond to such request (which shall in no event be less than fifteen (15) calendar days (or such shorter period as



may be agreed by the Administrative Agent) from the date of delivery of such notice to such Revolving Lenders) and shall agree to such procedures, if any, as may be established by, or reasonably acceptable to, the Administrative Agent to accomplish the purposes of this Section 2.19.

(b) Election to Extend. Any Revolving Lender wishing to have all (but not less than all) of its Revolving Commitments under the Existing Revolving Tranche amended into Extended Revolving Commitments (each, including any Additional Commitment Lenders (as defined below), an “Extending Revolving Lender”) specified in the Revolving Extension Request shall notify the Administrative Agent on or prior to the response date specified in such Revolving Extension Request of the Revolving Commitments it has elected to be amended. No Revolving Lender shall have any obligation to agree to provide any Extended Revolving Commitment pursuant to any Revolving Extension Request. Any Revolving Lender that determines not to extend its Revolving Commitments under the Existing Revolving Tranche, and notifies the Administrative Agent as to the same, or does not responding on or prior to such response date shall be deemed to have declined such Revolving Extension Request and, in each case, shall constitute a “Non-Consenting Lender” hereunder. The Administrative Agent shall notify the Company and each Revolving Lender under the applicable Existing Revolving Tranche of responses to such Revolving Extension Request. In the event that the aggregate principal amount of existing Revolving Commitments that the Extending Revolving Lenders have elected to amend pursuant to the relevant Revolving Extension Request exceeds the amount of Extended Revolving Commitments requested by the Borrowers, the principal amount of Extended Revolving Commitments requested by the Borrowers shall be allocated to each Extending Revolving Lender in such manner and in such amounts as may be agreed by Administrative Agent and the Company, in their sole discretion.

(c) Additional Commitment Lenders. The Company shall have the right to replace each Non-Consenting Lender with, and add as “Revolving Lenders” under this Agreement in place thereof, one or more Eligible Assignees (each, an “Additional Commitment Lender”) as provided in Section 11.13; provided that each of such Additional Commitment Lenders shall enter into an Assignment and Assumption in connection with any such Revolving Extension Request pursuant to which such Additional Commitment Lender shall undertake a Revolving Commitment (and, if any such Additional Commitment Lender is already a Lender, its Revolving Commitment shall be in addition to any other Revolving Commitment of such Lender hereunder on such date) from one or more Non-Consenting Lenders.

(d) Revolving Extension Amendment. Extended Revolving Commitments shall be established pursuant to an amendment (each, a “Revolving Extension Amendment”) to this Agreement among the Borrowers, the Administrative Agent and each Extending Revolving Lender, if any, providing an Extended Revolving Commitment, which shall be consistent with the provisions set forth in Sections 2.19(a), (b) and (d) (but which shall not require the consent of any other Lender). The



effectiveness of any Revolving Extension Amendment shall be subject to the satisfaction on the date thereof of each of the conditions set forth in Sections 4.02(a) and 4.02(b) (but solely limited to an Event of Default) (with all references in such Sections to a Credit Extension being deemed to be references to such Revolving Extension Request) and receipt of a certificate to that effect and, any other condition as may be agreed among the Borrowers, the Administrative Agent and the Extending Revolving Lenders. In addition, the Company shall have delivered, or cause to be delivered, customary legal opinions, officers' certificates, reaffirmation agreements and other documents consistent in all material respects with those delivered on the Closing Date under Section 4.01 with respect to the Company, the other Borrowers and all applicable Subsidiary Guarantors (other than changes to such legal opinions resulting from a change in Law, change in fact or change to counsel's form of opinion reasonably satisfactory to the Administrative Agent) as reasonably requested by the Administrative Agent in connection with each such extension. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Revolving Extension Amendment and the matters specified therein. Each of the parties hereto hereby agrees that this Agreement and the other Loan Documents may be amended pursuant to a Revolving Extension Amendment, without the consent of any other Lender, to the extent (but only to the extent) necessary to (i) reflect the existence and terms of the Extended Revolving Commitments incurred pursuant thereto, and (ii) effect such other amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent and the Borrowers, to effect the provisions of this Section 2.19, in each case, in a manner consistent with the terms of this Section 2.19, and the Required Lenders hereby expressly authorize the Administrative Agent to enter into any such Revolving Extension Amendment.

(e) Terms of Extended Revolving Commitments. Except as expressly provided herein, all Extended Revolving Commitments effected pursuant to any Revolving Extension Request and Revolving Extension Amendment shall be subject to the same terms, and shall be subject to the same conditions as the Existing Revolving Tranche. After giving effect to any Extended Revolving Commitment, all borrowings under the Revolving Commitments (including any such Extended Revolving Commitments) and repayments thereunder shall be made on a pro rata basis (except for (x) any payments of interest and fees at different rates on any Revolving Extension Series (and related Loans thereunder), (y) repayments required upon the applicable Maturity Date of other Revolving Commitments and (z) except as otherwise expressly set forth herein). If a Revolving Extension Amendment has become effective hereunder, not later than the third Business Day prior to the Existing Maturity Date, the Borrowers shall make prepayments of Revolving Loans and shall Cash Collateralize Letters of Credit, such that, after giving effect to such prepayments and such provision of Cash Collateral, the aggregate Revolving Exposure as of such date will not exceed the aggregate applicable Extended Revolving Commitments of the Extended Revolving Lenders (and the Borrowers shall not be permitted thereafter to request any Revolving Loan or any issuance, amendment, renewal or extension of a Letter of Credit if, after giving effect



thereto, the applicable Revolving Exposure would exceed the aggregate amount of the Extended Revolving Commitments then in effect).

(f) Revolving Extension Series. Any Extended Revolving Commitments effected pursuant to a Revolving Extension Request shall be designated a series (each, a “Revolving Extension Series”) of Extended Revolving Commitments for all purposes of this Agreement; provided that any Extended Revolving Commitments effected from an Existing Revolving Tranche may, to the extent provided in the applicable Revolving Extension Amendment, be designated as an increase in any previously established Revolving Extension Series with respect to such Existing Revolving Tranche. In connection with the foregoing, Schedule 1.01(b) attached hereto shall be updated to reflect each applicable Revolving Extension Series, in a manner reasonably satisfactory to the Administrative Agent.

(g) Changes to Applicable Rate. In connection with any extension of the Maturity Date made pursuant to this Section 2.19, the Applicable Rate applicable to Loans made and to be made by Extending Revolving Lenders may be modified without any consent of any other Lender, provided that no such modification shall apply to the Loans of the other Lenders unless the Company and the Administrative Agent (without any requirement of consultation with or approval by any other Lender) determine that such change should apply to the Loans of the other Lenders and either (i) such other Lender has consented to such change (notwithstanding its such Lender is not consenting to the applicable extension of the Maturity Date) or (ii) such change represents an increase in the Applicable Rate applicable to the Loans of the other Lenders.

(h) Conflicting Provisions. This Section 2.19 shall supersede any provisions in Section 2.13 or 11.01 to the contrary.

## ARTICLE III

## TAXES, YIELD PROTECTION AND ILLEGALITY

## 3.01 Taxes.

(a) Payments Free of Taxes; Obligation to Withhold; Payments on Account of Taxes.

(i) Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable Laws. If any applicable Laws (as determined in the good faith discretion of the Administrative Agent) require the deduction or withholding of any Tax from any such payment by the Administrative Agent or a Loan Party, then the Administrative Agent or such Loan Party shall be entitled to make such deduction or withholding, upon the basis of the information and documentation to be delivered pursuant to this Section 3.01.



(ii) If any Loan Party or the Administrative Agent shall be required by the Code to withhold or deduct any Taxes, including both United States federal backup withholding and withholding taxes, from any payment, then (A) the Administrative Agent shall withhold or make such deductions as are determined by the Administrative Agent to be required based upon the information and documentation it has received pursuant to this Section 3.01, (B) the Administrative Agent shall timely pay the full amount withheld or deducted to the relevant Governmental Authority in accordance with the Code and (C) to the extent that the withholding or deduction is made on account of Indemnified Taxes, the sum payable by the applicable Loan Party shall be increased as necessary so that after any required withholding or the making of all required deductions (including withholdings and deductions applicable to additional sums payable under this Section 3.01) the applicable Recipient receives an amount equal to the sum it would have received had no such withholding or deduction been made.

(iii) If any Loan Party or the Administrative Agent shall be required by any applicable Laws other than the Code to withhold or deduct any Taxes from any payment, then (A) such Loan Party or the Administrative Agent, as required by such Laws, shall withhold or make such deductions as are determined by it to be required based upon the information and documentation it has received pursuant to this Section 3.01, (B) such Loan Party or the Administrative Agent, to the extent required by such Laws, shall timely pay the full amount withheld or deducted to the relevant Governmental Authority in accordance with such Laws and (C) to the extent that the withholding or deduction is made on account of Indemnified Taxes, the sum payable by the applicable Loan Party shall be increased as necessary so that after any required withholding or the making of all required deductions (including withholdings and deductions applicable to additional sums payable under this Section 3.01) the applicable Recipient receives an amount equal to the sum it would have received had no such withholding or deduction been made.

(iv) A Loan Party shall promptly upon becoming aware that it must make a deduction or withholding for any Taxes from a payment under any Loan Document (or that there is a change in the rate or the basis of such deduction or withholding) notify the Administrative Agent (who shall notify any relevant Lenders) accordingly.

(b) Payment of Other Taxes by the Loan Parties. Without limiting the provisions of subsection (a) above, the Loan Parties shall timely pay to the relevant Governmental Authority in accordance with applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.



## (c) Tax Indemnifications.

(i) Each of the Loan Parties shall, and does hereby, jointly and severally indemnify each Recipient, and shall make payment in respect thereof within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 3.01) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the applicable Loan Party by a Lender or an L/C Issuer (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or an L/C Issuer, shall be conclusive absent manifest error. Each of the Loan Parties shall also, and does hereby, jointly and severally indemnify the Administrative Agent, and shall make payment in respect thereof within ten (10) days after demand therefor, for any amount which a Lender or an L/C Issuer for any reason fails to pay indefeasibly to the Administrative Agent as required pursuant to Section 3.01(c)(ii) below.

(ii) Each Lender and each L/C Issuer shall, and does hereby, severally indemnify and shall make payment in respect thereof within ten (10) days after demand therefor, (A) the Administrative Agent against any Indemnified Taxes attributable to such Lender or such L/C Issuer (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (B) the Administrative Agent and the Loan Parties, as applicable, against any Taxes attributable to such Lender’s failure to comply with the provisions of Section 11.06(d) relating to the maintenance of a Participant Register and (C) the Administrative Agent and the Loan Parties, as applicable, against any Excluded Taxes attributable to such Lender or such L/C Issuer, in each case, that are payable or paid by the Administrative Agent or a Loan Party in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender and each L/C Issuer hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender or such L/C Issuer, as the case may be, under this Agreement or any other Loan Document against any amount due to the Administrative Agent under this clause (ii).

(d) Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority, as provided in this Section 3.01, the



applicable Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of any return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

## (e) Status of Lenders; Tax Documentation.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the applicable Borrower and the Administrative Agent, at the time or times reasonably requested by the applicable Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the applicable Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the applicable Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the applicable Borrower or the Administrative Agent as will enable the applicable Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.01(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, in the event that the applicable Borrower is a U.S. Person (including the Company),

(A) any Lender that is a U.S. Person shall deliver to the Company and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Company and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), whichever of the following is applicable:



(1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN-E (or W-8BEN, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN-E (or W-8BEN, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2) executed originals of IRS Form W-8ECI;

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit I-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Company within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN-E (or W-8BEN, as applicable); or

(4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E (or W-8BEN, as applicable), a U.S. Tax Compliance Certificate substantially in the form of Exhibit I-2 or Exhibit I-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit I-4 on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Company and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), executed copies (or originals, as required) of any other form prescribed by applicable Law as a



basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable Law to permit the Company or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Company and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Company or the Administrative Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Company or the Administrative Agent as may be necessary for the Company and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), "FATCA" shall include any amendments made to FATCA after the date of this Agreement.

(iii) Each Lender agrees that if any form or certification it previously delivered pursuant to this Section 3.01 expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the applicable Borrower and the Administrative Agent in writing of its legal inability to do so.

(f) An Irish Treaty Lender and the applicable Borrower shall co-operate in completing any procedural formalities necessary for the applicable Borrower to obtain authorization to make a payment to that Irish Treaty Lender without any deduction or withholding of any tax imposed by Ireland.

(g) In respect of Loans advanced to a Loan Party that is within the charge to UK Taxes United Kingdom corporation tax:

(i) Subject to Section 3.01(g)(ii), a UK Treaty Lender and each Loan Party which makes a payment under a Loan Document to which that UK Treaty Lender is entitled shall cooperate in completing any procedural formalities necessary for such Loan Party to obtain authorization to make that payment without a UK Tax Deduction, including making and filing of an appropriate application for relief under an applicable Treaty.



(ii) A UK Treaty Lender that holds a passport under the HMRC Double Taxation Treaty Passport Scheme (“UK DTTP Scheme”) and which wishes the UK DTTP Scheme to apply to this Agreement, shall confirm its scheme reference number and jurisdiction of tax residence in: (A) where the UK Treaty Lender is a Lender on the date of this Agreement, Schedule 1.01(d) to this Agreement; or (B) where the UK Treaty Lender becomes a Lender after the date of this Agreement, the relevant Assignment and Assumption, and, having done so, that UK Treaty Lender shall be under no obligation pursuant to Section 3.01(g)(i) to cooperate with the relevant Loan Party but, for avoidance of doubt, such UK Treaty Lender shall have an obligation to cooperate further with the relevant Loan Party in accordance with Section 3.01(g)(iii).

(iii) If a UK Treaty Lender has confirmed its scheme reference number and its jurisdiction of tax residence in accordance with Section 3.01(g)(ii) and:

(A) a Loan Party making a payment to that UK Treaty Lender has not made a UK DTTP Filing in respect of that UK Treaty Lender; or

(B) a Loan Party making a payment to that UK Treaty Lender has made a UK DTTP Filing in respect of that Lender but either (a1) that UK DTTP Filing has been rejected by HMRC or (b2) HMRC has not given the Loan Party authority to make payments to that UK Treaty Lender without a UK Tax Deduction within forty (40) Business Days of the date of the UK DTTP Filing, and in each case, the relevant Loan Party has notified that UK Treaty Lender in writing, that UK Treaty Lender and the Loan Party shall cooperate in completing any additional procedural formalities necessary for that Loan Party to obtain authorization to make that payment without a UK Tax Deduction.

(iv) If a Lender has not confirmed its scheme reference number and jurisdiction of tax residence in accordance with Section 3.01(g)(ii), no Loan Party shall make a UK DTTP Filing or file any other form relating to the UK DTTP Scheme in respect of that Lender's Revolving Commitment or participation in any Loan unless the Lender otherwise agrees.

(v) A Loan Party shall, promptly after making a UK DTTP Filing, deliver a copy of the UK DTTP Filing to the Administrative Agent for delivery to the relevant Lender.

(vi) A Lender that is a Lender on the date of this Agreement that is a UK Qualifying Lender solely by virtue of sub-paragraph (b) of the definition of UK Qualifying Lender gives a UK Tax Confirmation to Company by entering into the Agreement. A Lender that is a UK Qualifying Lender solely by virtue of sub-paragraph (b) of the definition of UK Qualifying Lender shall promptly notify Company and the Administrative Agent if there is any change in the position from that set out in the UK Tax Confirmation.



(vii) Each Lender which is not a Lender on the date of this Agreement shall indicate in the relevant Assignment and Assumption, for the benefit of the Administrative Agent, but without liability to any Loan Party, whether it is:

(A) not a UK Qualifying Lender;

(B) a UK Qualifying Lender (that is not a UK Treaty Lender); or

(C) a UK Treaty Lender.

If a Lender fails to indicate its status in accordance with this Section 3.01(g)(vii) then such Lender shall be treated for the purposes of this Agreement (including by each Loan Party) as if it is not a UK Qualifying Lender until such time as it notifies the Administrative Agent (and the Administrative Agent, upon receipt of such notification, shall inform the Company). For the avoidance of doubt, an Assignment and Assumption shall not be invalidated by any failure of a Lender to comply with this Section 3.01(g)(vii).

(h) Each Lender which is not a Lender on the date of this Agreement shall indicate in the relevant Assignment and Assumption, for the benefit of the Administrative Agent, but without liability to any Loan Party, whether it is:

(i) not an Irish Qualifying Lender;

(ii) an Irish Qualifying Lender (that is not an Irish Treaty Lender); or

(iii) an Irish Treaty Lender.

If a Lender fails to indicate its status in accordance with this Section 3.01(h) then such Lender shall be treated for the purposes of this Agreement (including by each Loan Party) as if it is not an Irish Qualifying Lender until such time as it notifies the Administrative Agent (and the Administrative Agent, upon receipt of such notification, shall inform the Company). For the avoidance of doubt, an Assignment and Assumption shall not be invalidated by any failure of a Lender to comply with this Section 3.01(h).

(i) Treatment of Certain Refunds. Unless required by applicable Laws, at no time shall the Administrative Agent have any obligation to file for or otherwise pursue on behalf of a Lender or an L/C Issuer, or have any obligation to pay to any Lender or any L/C Issuer, any refund of Taxes withheld or deducted from funds paid for the account of such Lender or such L/C Issuer, as the case may be. If any Recipient determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified by any Loan Party or with respect to which any Loan Party has paid additional amounts pursuant to this Section 3.01, it shall pay to such Loan Party



an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by such Loan Party under this Section 3.01 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) incurred by such Recipient, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that each Loan Party, upon the request of the Recipient, agrees to repay the amount paid over to such Loan Party (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Recipient in the event the Recipient is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this subsection, in no event will the applicable Recipient be required to pay any amount to such Loan Party pursuant to this subsection the payment of which would place the Recipient in a less favorable net after-Tax position than such Recipient would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This subsection shall not be construed to require any Recipient to make available its tax returns (or any other information relating to its taxes that it deems confidential) to any Loan Party or any other Person.

(j) Survival. Each party’s obligations under this Section 3.01 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender or an L/C Issuer, the termination of the Revolving Commitments and the repayment, satisfaction or discharge of all other Obligations.

## 3.02 Illegality.

(a) If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund or charge interest with respect to any Credit Extension, or to determine or charge interest rates based upon the Eurocurrency Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars or any Alternative Currency in the applicable interbank market, then, upon notice thereof by such Lender to the Company (through the Administrative Agent), (i) any obligation of such Lender to make or continue Eurocurrency Rate Loans in the affected currency or currencies or, in the case of Eurocurrency Rate Loans in Dollars, to convert Base Rate Loans to Eurocurrency Rate Loans, shall be suspended, and (ii) if such notice asserts the illegality of such Lender making or maintaining Base Rate Loans the interest rate on which is determined by reference to the Eurocurrency Rate component of the Base Rate, the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Eurocurrency Rate component of the Base Rate, in each case until such Lender notifies the Administrative Agent and the Company that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (A) the Borrowers shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable and such



Loans are denominated in Dollars, convert all Eurocurrency Rate Loans of such Lender to Base Rate Loans (the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Eurocurrency Rate component of the Base Rate), either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurocurrency Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurocurrency Rate Loans and (B) if such notice asserts the illegality of such Lender determining or charging interest rates based upon the Eurocurrency Rate, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender without reference to the Eurocurrency Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the Eurocurrency Rate. Upon any such prepayment or conversion, the Borrowers shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 3.05.

(b) If, in any applicable jurisdiction, the Administrative Agent, the applicable L/C Issuer or any Lender or any Designated Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for the Administrative Agent, the applicable L/C Issuer or any Lender or its applicable Designated Lender to (i) perform any of its obligations hereunder or under any other Loan Document, (ii) to fund, hold a commitment or maintain its participation in any Loan or Letter of Credit or (iii) issue, make, maintain, fund or charge interest or fees with respect to any Credit Extension, such Person shall promptly notify the Administrative Agent, then, upon the Administrative Agent notifying the Company, and until such notice by such Person is revoked, any obligation of such Person to issue, make, maintain, fund or charge interest or fees with respect to any such Credit Extension shall be suspended, and to the extent required by applicable Law, cancelled. Upon receipt of such notice, the Loan Parties shall, (A) repay that Person's participation in the Loans or other applicable Obligations on the last day of the Interest Period for each Loan or other Obligation occurring after the Administrative Agent has notified the Company or, if earlier, the date specified by such Person in the notice delivered to the Administrative Agent (being no earlier than the last day of any applicable grace period permitted by applicable Law), (B) to the extent applicable to the applicable L/C Issuer, Cash Collateralize that portion of applicable L/C Obligations comprised of the aggregate undrawn amount of Letters of Credit to the extent not otherwise Cash Collateralized and (C) take all reasonable actions requested by such Person to mitigate or avoid such illegality.

## 3.03 Inability to Determine Rates.

(a) If in connection with any request for a Eurocurrency Rate Loan or a conversion to or continuation thereof, (i) the Administrative Agent determines that (A) deposits (whether in Dollars or an Alternative Currency) are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurocurrency Rate Loan, (B) (1) adequate and



reasonable means do not exist for determining the Eurocurrency Rate for any requested Interest Period with respect to a proposed Eurocurrency Rate Loan (whether denominated in Dollars or an Alternative Currency) or in connection with an existing or proposed Base Rate Loan and (2) the circumstances described in Section 3.03(c)(i) do not apply or (C) a fundamental change has occurred in the foreign exchange or interbank markets with respect to such Alternative Currency (including, without limitation, changes in national or international financial, political or economic conditions or currency exchange rates or exchange controls) (in each case with respect to this clause (i), “Impacted Loans”) or (ii) the Administrative Agent or the Required Lenders determine that for any reason Eurocurrency Rate for any requested Interest Period with respect to a proposed Eurocurrency Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will promptly so notify the Company and each Lender. Thereafter, (x) the obligation of the Lenders to make or maintain Eurocurrency Rate Loans in the affected currency or currencies shall be suspended (to the extent of the affected Eurocurrency Rate Loans or Interest Periods), and (y) in the event of a determination described in the preceding sentence with respect to the Eurocurrency Rate component of the Base Rate, the utilization of the Eurocurrency Rate component in determining the Base Rate shall be suspended, in each case until the Administrative Agent (or, in the case of a determination by the Required Lenders described in clause (ii) of this Section 3.03(a), until the Administrative Agent upon instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the Company may revoke any pending request for a Borrowing of, conversion to or continuation of Eurocurrency Rate Loans in the affected currency or currencies (to the extent of the affected Eurocurrency Rate Loans or Interest Periods) or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in Dollars in the amount specified therein.

(b) Notwithstanding the foregoing, if the Administrative Agent has made the determination described in clause (a) (i) of this Section 3.03, the Administrative Agent in consultation with the Company, may establish an alternative interest rate for the Impacted Loans, in which case, such alternative rate of interest shall apply with respect to the Impacted Loans until (i) the Administrative Agent revokes the notice delivered with respect to the Impacted Loans under clause (a)(i) of this Section 3.03, (ii) the Administrative Agent or the Required Lenders notify the Administrative Agent and the Company that such alternative interest rate does not adequately and fairly reflect the cost to such Lenders of funding the Impacted Loans or (iii) any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for such Lender or its applicable Lending Office to make, maintain or fund Loans whose interest is determined by reference to such alternative rate of interest or to determine or charge interest rates based upon such rate or any Governmental Authority has imposed material restrictions on the authority of such Lender to do any of the foregoing and provides the Administrative Agent and the Company written notice thereof.



(c) Notwithstanding anything to the contrary in this Agreement or any other Loan Documents, but without limiting Sections 3.01(a) and (b) above, if the Administrative Agent determines (which determination shall be conclusive and binding upon all parties hereto absent manifest error), or the Company or Required Lenders notify the Administrative Agent (with, in the case of the Required Lenders, a copy to the Company) that the Company or Required Lenders (as applicable) have determined (which determination likewise shall be conclusive and binding upon all parties hereto absent manifest error), that:

(i) adequate and reasonable means do not exist for ascertaining LIBOR for any requested Interest Period, including, without limitation, because the LIBOR Screen Rate is not available or published on a current basis and such circumstances are unlikely to be temporary; or

(ii) the administrator of the LIBOR Screen Rate or a Governmental Authority having or purporting to have jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which LIBOR or the LIBOR Screen Rate shall no longer be made available, or used for determining the interest rate of loans in the applicable currency; provided that, at the time of such statement, there is no successor administrator that is satisfactory to the Administrative Agent, that will continue to provide LIBOR after such specific date (such specific date, the “Scheduled Unavailability Date”), or

(iii) syndicated loans currently being executed, or that include language similar to that contained in this Section 3.03, are being executed or amended (as applicable) to incorporate or adopt a new benchmark interest rate to replace LIBOR,

then, reasonably promptly after such determination by the Administrative Agent or receipt by the Administrative Agent of such notice, as applicable, the Administrative Agent and the Company may amend this Agreement to replace LIBOR in accordance with this Section 3.03 with (x) one or more SOFR-Based Rates (which shall be applicable only to Loans denominated in Dollars) or (y) another alternate benchmark rate giving due consideration to any evolving or then existing convention for similar U.S.-dollar Dollar denominated syndicated credit facilities for such alternative benchmarks and, in each case, including any mathematical or other adjustments to such benchmark giving due consideration to any evolving or then existing convention for similar U.S.-dollar Dollar denominated syndicated credit facilities for such benchmarks, which adjustment or method for calculating such adjustment shall be published on an information service as selected by the Administrative Agent from time to time in its reasonable discretion and may be periodically updated (the “Adjustment”; and any such proposed rate, a “LIBOR Successor Rate”), and any such amendment shall become effective at 5:00 p.m. on the fifth Business Day after the Administrative Agent shall have posted such proposed amendment to all Lenders and the Company unless, prior to such time, Lenders comprising the Required Lenders have delivered to the Administrative Agent written



notice that such Required Lenders (A) in the case of an amendment to replace LIBOR with a rate described in clause (x), object to the Adjustment; or (B) in the case of an amendment to replace LIBOR with a rate described in clause (y), object to such amendment; provided that for the avoidance of doubt, in the case of clause (A), the Required Lenders shall not be entitled to object to any SOFR-Based Rate contained in any such amendment. Such LIBOR Successor Rate shall be applied in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible for the Administrative Agent, such LIBOR Successor Rate shall be applied in a manner as otherwise reasonably determined by the Administrative Agent.

If no LIBOR Successor Rate has been determined and the circumstances under clause (c)(i) above exist or the Scheduled Unavailability Date has occurred (as applicable), the Administrative Agent will promptly so notify the Company and each Lender. Thereafter, (i) the obligation of the Lenders to make or maintain Eurocurrency Rate Loans in the affected currency or currencies shall be suspended (to the extent of the affected Eurocurrency Rate Loans or Interest Periods), and (ii) the Eurocurrency Rate component shall no longer be utilized in determining the Base Rate. Upon receipt of such notice, the Company may revoke any pending request for a Borrowing of, conversion to or continuation of Eurocurrency Rate Loans in the affected currency or currencies (to the extent of the affected Eurocurrency Rate Loans or Interest Periods) or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans (subject to the foregoing clause (ii)) in Dollars in the amount specified therein.

Notwithstanding anything else herein, any definition of LIBOR Successor Rate shall provide that in no event shall such LIBOR Successor Rate be less than zero for purposes of this Agreement.

In connection with the implementation of a LIBOR Successor Rate, the Administrative Agent will have the right to make LIBOR Successor Rate Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such LIBOR Successor Rate Conforming Changes will become effective without any further action or consent of any other party to this Agreement; provided that, with respect to any such amendment effected, the Administrative Agent shall post each such amendment implementing LIBOR Successor Rate Conforming Changes to the Company and the Lenders reasonably promptly after such amendment becomes effective.

For purposes hereof:

“LIBOR Successor Rate Conforming Changes” means, with respect to any proposed LIBOR Successor Rate, any conforming changes to the definition of Base Rate, Interest Period, timing and frequency of determining rates and making payments of interest and other technical, administrative or operational matters as may be appropriate, in the discretion of the Administrative Agent, to reflect the adoption and implementation of such LIBOR Successor Rate and to permit the administration thereof by the



Administrative Agent in a manner substantially consistent with market practice (or, if the Administrative Agent determines that adoption of any portion of such market practice is not administratively feasible or that no market practice for the administration of such LIBOR Successor Rate exists, in such other manner of administration as the Administrative Agent determines is reasonably necessary in connection with the administration of this Agreement).

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York for the purpose of recommending a benchmark rate to replace LIBOR in loan agreements similar to this Agreement.

“SOFR” with respect to any day means the secured overnight financing rate published for such day by the Federal Reserve Bank of New York, as the administrator of the benchmark (or a successor administrator) on the Federal Reserve Bank of New York’s website (or any successor source) and, in each case, that has been selected or recommended by the Relevant Governmental Body.

“SOFR-Based Rate” means SOFR or Term SOFR.

“Term SOFR” means the forward-looking term rate for any period that is approximately (as determined by the Administrative Agent) as long as any of the Interest Period options set forth in the definition of “Interest Period” and that is based on SOFR and that has been selected or recommended by the Relevant Governmental Body, in each case as published on an information service as selected by the Administrative Agent from time to time in its reasonable discretion.

## 3.04 Increased Costs; Reserves on Eurocurrency Rate Loans.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement contemplated by Section 3.04(e)) or any L/C Issuer;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Excluded Taxes (other than those described in clause (a) of the definition of Excluded Taxes) and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or any L/C Issuer or the London interbank market any other condition, cost or expense affecting this Agreement or



Eurocurrency Rate Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making, converting to, continuing or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or such L/C Issuer of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or such L/C Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or such L/C Issuer, the Company will pay (or cause the applicable Designated Foreign Borrower to pay) to such Lender or such L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or such L/C Issuer, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or any L/C Issuer determines that any Change in Law affecting such Lender or such L/C Issuer or any Lending Office of such Lender or such Lender’s or such L/C Issuer’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or such L/C Issuer’s capital or on the capital of such Lender’s or such L/C Issuer’s holding company, if any, as a consequence of this Agreement, the Revolving Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingle Loans held by, such Lender, or the Letters of Credit issued by such L/C Issuer, to a level below that which such Lender or such L/C Issuer or such Lender’s or such L/C Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such L/C Issuer’s policies and the policies of such Lender’s or such L/C Issuer’s holding company with respect to capital adequacy or liquidity), then from time to time the Company will pay (or cause the applicable Designated Foreign Borrower to pay) to such Lender or such L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or such L/C Issuer or such Lender’s or such L/C Issuer’s holding company for any such reduction suffered.

## (c) [Reserved].

(d) Certificates for Reimbursement. A certificate of a Lender or an L/C Issuer setting forth in reasonable detail the amount or amounts necessary to compensate such Lender or such L/C Issuer or its holding company, as the case may be, as specified in clause (a) or (b) of this Section 3.04, including the basis and calculation thereof, shall be delivered to the Company and shall be conclusive absent manifest error. The Company shall pay (or cause the applicable Designated Foreign Borrower to pay) such Lender or such L/C Issuer, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(e) Reserves on Eurocurrency Rate Loans. The Company shall pay (or cause the applicable Designated Foreign Borrower to pay) to each Lender, (i) as long as such Lender shall be required to maintain reserves with respect to liabilities or assets



consisting of or including eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional interest on the unpaid principal amount of each Eurocurrency Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive) and (ii) as long as such Lender shall be required to comply with any reserve ratio requirement or analogous requirement of any central banking or financial regulatory authority imposed in respect of the maintenance of the Revolving Commitments or the funding of the Loans, such additional costs (expressed as a percentage per annum and rounded upwards, if necessary, to the nearest five decimal places) equal to the actual costs allocated to such Revolving Commitment or Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which in each case shall be due and payable on each date on which interest is payable on such Loan, provided the Company shall have received at least ten (10) days’ prior notice (with a copy to the Administrative Agent) of such additional interest or costs from such Lender. If a Lender fails to give notice ten (10) days prior to the relevant Interest Payment Date, such additional interest shall be due and payable ten (10) days from receipt of such notice.

(f) Delay in Requests. Failure or delay on the part of any Lender or any L/C Issuer to demand compensation pursuant to the foregoing provisions of this Section 3.04 shall not constitute a waiver of such Lender’s or such L/C Issuer’s right to demand such compensation, provided that the Borrowers shall not be required to compensate a Lender or an L/C Issuer pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than nine (9) months prior to the date that such Lender or such L/C Issuer, as the case may be, notifies the Company of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine (9) month period referred to above shall be extended to include the period of retroactive effect thereof).

## 3.05 Compensation for Losses.

Upon written demand of any Lender (with a copy to the Administrative Agent) from time to time, setting forth in reasonable detail the basis for, and manner of calculating such compensation, the Company shall promptly compensate (or cause the applicable Designated Foreign Borrower to compensate) such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

(b) any failure by the Borrowers (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a



Base Rate Loan on the date or in the amount notified by the Company (or the applicable Designated Foreign Borrower);

(c) any assignment of a Eurocurrency Rate Loan on a day other than the last day of the Interest Period therefor as a result of a request by the Company pursuant to Section 11.13; or

(d) any failure by any Borrower to make payment of any Loan or drawing under any Letter of Credit (or interest due thereon) denominated in an Alternative Currency on its scheduled due date or any payment thereof in a different currency;

including any foreign exchange losses and any loss or expense (but excluding any loss of anticipated profits) arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign exchange contract (but excluding any loss of anticipated profits). The Company shall also pay (or cause the applicable Designated Foreign Borrower to pay) any customer administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Company (or the applicable Designated Foreign Borrower) to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurocurrency Rate Loan made by it at the Eurocurrency Rate for such Loan by a matching deposit or other borrowing in the offshore interbank market for such currency for a comparable amount and for a comparable period, whether or not such Eurocurrency Rate Loan was in fact so funded.

## 3.06 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or requires the Borrowers to pay any Indemnified Taxes or additional amounts to any Lender, any L/C Issuer, or any Governmental Authority for the account of any Lender or any L/C Issuer pursuant to Section 3.01, or if any Lender gives a notice pursuant to Section 3.02, then at the request of the Company, such Lender or such L/C Issuer shall, as applicable, use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender or such L/C Issuer, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject such Lender or such L/C Issuer, as the case may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or such L/C Issuer, as the case may be. The Company hereby agrees to pay (or cause the applicable Designated Foreign Borrower to pay) all reasonable costs and expenses incurred by any Lender or any L/C Issuer in connection with any such designation or assignment.



(b) Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if the Borrowers are required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 3.06(a), the Company may replace such Lender in accordance with Section 11.13.

## 3.07 Survival.

All of the Borrowers’ obligations under this Article III and the Lenders’ obligations under Section 3.01(c)(ii) shall, in each case, survive termination of the Aggregate Revolving Commitments, repayment of all other Obligations hereunder, resignation of the Administrative Agent and the Facility Termination Date.

To the best knowledge of the Loan Parties, nothing has occurred that would prevent or cause the loss of such tax-qualified status other than qualification defects that can be corrected under the Employee Plans Compliance Resolution System described in IRS Revenue Procedure 2019-19 where such correction would not be expected to result in a Material Adverse Effect.

(d) With respect to each scheme or arrangement mandated by a government other than the United States (a “Foreign Government Scheme or Arrangement”) and with respect to each employee benefit plan maintained or contributed to by any Loan Party or any of their respective Restricted Subsidiaries that is not subject to United States Law (a “Foreign Plan”), except as would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect:

(i) any employer and employee contributions required by law or by the terms of any Foreign Government Scheme or Arrangement or any Foreign Plan have been made, or, if applicable, accrued, in accordance with normal accounting practices of the jurisdiction in which such plan is maintained;

Third, to payment of that portion of the Guaranteed Obligations constituting accrued and unpaid Letter of Credit Fees and interest on the Loans, L/C Borrowings and other Guaranteed Obligations arising under the Loan Documents, ratably among the Lenders and the L/C Issuers in proportion to the respective amounts described in this clause Third payable to them;

Subject to Sections 2.03(c) and 2.14, amounts used to Cash Collateralize the aggregate undrawn amount of Letters of Credit pursuant to clause Fourth above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied to the other Guaranteed Obligations, if any, in the order set forth above. Excluded Swap Obligations with respect to any Guarantor shall not be paid with amounts received from



such Guarantor or its assets, but appropriate adjustments shall be made with respect to payments from other Loan Parties to preserve the allocation to Guaranteed Obligations otherwise set forth above in this Section.

Notwithstanding the foregoing, (a) Guaranteed Obligations arising under Guaranteed Cash Management Agreements and Guaranteed Hedge Agreements shall be excluded from the application described above if the Administrative Agent has not received a Guaranteed Party Designation Notice, together with such supporting documentation as the Administrative Agent may reasonably request, from the applicable Cash Management Bank or Hedge Bank, as the case may be, and (b) no amounts received from or on account of a Designated Foreign Borrower shall be used to pay or applied against any Guaranteed Obligations of or attributable to any U.S. Loan Party or any other Domestic Subsidiary.

## ARTICLE IX

## ADMINISTRATIVE AGENT

## 9.01 Appointment and Authority.

Each of the Lenders and each of the L/C Issuers hereby irrevocably appoints, designates and authorizes Bank of America to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article IX are solely for the benefit of the Administrative Agent, the Lenders and the L/C Issuers, and neither the Borrowers nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law.

(iii) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty or responsibility to disclose, and shall not be liable for the failure to disclose, any information relating to any Loan Lender or any L/C Issuer any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Party Parties or any of its their Affiliates that is communicated to, or obtained by in the Person serving as possession of, the Administrative Agent, Arranger or any of its Affiliates their Related Parties in any capacity, except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein.

(c) Neither the Administrative Agent nor any of its Related Parties shall be responsible or have any liability for, or have any duty to ascertain, inquire into, monitor or enforce, compliance with the provisions of this Agreement relating to Disqualified Institutions. Without limiting the generality of the foregoing, the Administrative Agent shall not (i) be obligated to ascertain, monitor or inquire as to whether any Lender or prospective Lender is a Disqualified Institution or (ii) have any liability with respect to or arising out of any assignment of Loans, or disclosure of confidential information to any Disqualified Institution.

In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or such L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or such L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable



for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objections.

If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders and the L/C Issuers, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that in no event shall any successor Administrative Agent be a Defaulting Lender or a Disqualified Institution. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b) Defaulting Lender. If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable Law, by notice in writing to the Company and



such Person remove such Person as Administrative Agent and, in consultation with the Company, appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c) Effect of Resignation or Removal. With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (i) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the L/C Issuers under any of the Loan Documents, the retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (ii) except for any indemnity payments or other amounts then owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and each L/C Issuer directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor's appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or removed) Administrative Agent (other than as provided in Section 3.01(j) and other than any rights to indemnity payments or other amounts owed to the retiring or removed Administrative Agent as of the Resignation Effective Date or the Removal Effective Date, as applicable), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Company to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Company and such successor, and the retiring or removed Administrative Agent shall cease to be entitled to all such fees upon the effectiveness of its resignation or removal as Administrative Agent, except to the extent it continues to act in any capacity hereunder or under the other Loan Documents after such resignation or removal. After the retiring or removed Administrative Agent's resignation or removal hereunder and under the other Loan Documents, the provisions of this Article XI and Section 11.04 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them (A) while the retiring or removed Administrative Agent was acting as Administrative Agent and (B) after such resignation or removal for as long as any of them continues to act in any capacity hereunder or under the other Loan Documents, including, without limitation, (1) acting as collateral agent or otherwise holding any collateral security on behalf of any of the Credit Parties and (2) in respect of any actions taken in connection with transferring the agency to any successor Administrative Agent.



(d) L/C Issuer and Swingline Lender. Any resignation or removal by Bank of America as Administrative Agent pursuant to this Section 9.06 shall also constitute its resignation as an L/C Issuer and Swingline Lender. If Bank of America resigns as an L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuers hereunder with respect to all Letters of Credit issued by it outstanding as of the effective date of its resignation as an L/C Issuer and all L/C Obligations with respect thereto, including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c). If Bank of America resigns as Swingline Lender, it shall retain all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans or fund risk participations in outstanding Swingline Loans pursuant to Section 2.04(c). Upon the appointment by the Company of a successor L/C Issuer or Swingline Lender hereunder (which successor shall in all cases be a Lender other than a Defaulting Lender), (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swingline Lender, as applicable, (ii) the retiring L/C Issuer and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (iii) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

document furnished hereunder or thereunder, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties. Each Lender and each L/C Issuer represents and warrants that (i) the Loan Documents set forth the terms of a commercial lending facility and (ii) it is engaged in making, acquiring or holding commercial loans in the ordinary course and is entering into this Agreement as a Lender or L/C Issuer for the purpose of making, acquiring or holding commercial loans and providing other facilities set forth herein as may be applicable to such Lender or L/C Issuer, and not for the purpose of purchasing, acquiring or holding any other type of financial instrument, and each Lender and each L/C Issuer agrees not to assert a claim in contravention of the foregoing.

## ARTICLE X
CONTINUING GUARANTY

## 10.01 Guaranty.

Each Guarantor hereby absolutely and unconditionally, jointly and severally guarantees, as primary obligor and as a guaranty of payment and performance and not merely as a guaranty of collection, prompt payment when due, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of any and all Obligations and Additional Obligations (or, if the scope of such Guarantor's Guaranty is limited to a portion of the Obligations and/or Additional Obligations under the definition of "Guarantors", such portion) (collectively, for each Guarantor, subject to the proviso in this sentence, its "Guaranteed Obligations"); provided that (a) the Guaranteed Obligations of a Guarantor shall exclude any Excluded Swap Obligations with respect to such Guarantor, (b) the liability of each Guarantor individually with respect to this Guaranty shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the Bankruptcy Code of the United States or any comparable provisions of any applicable state law or other applicable Law, (c) for avoidance of doubt, the Designated Foreign Borrowers shall not be liable under this Guaranty for any Obligations or Additional Obligations of or attributable to any U.S. Loan Party or any other Domestic Subsidiary, (d) the guaranty given by a Guarantor which is incorporated in England and Wales does not apply to any liability to the extent that it would result in this Guaranty constituting unlawful financial assistance within the meaning of sections 678 or 679 of the Companies Act 2006, and (e) notwithstanding anything contrary in this Section 10.1, the guaranty under this Section 10.1 of any Guarantor incorporated in Ireland does not apply to any liability to the extent that it would (A) result in this Guaranty constituting unlawful financial assistance within the meaning of section 82 of the Companies Act 2014 of Ireland; or (B) constitute a breach of section 239 of the Companies Act 2014 of Ireland. Without limiting the generality of the foregoing, the Guaranteed Obligations shall include any such indebtedness, obligations, and liabilities with respect to Guaranteed Obligations, or portion thereof, which may be or hereafter become unenforceable or compromised or shall be an allowed or disallowed claim under any proceeding or case commenced by or against any Debtor under any Debtor Relief Laws. The Administrative Agent's books and records showing the amount of the Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon each Guarantor, and conclusive for the purpose of establishing the amount of the Guaranteed Obligations absent manifest error. This Guaranty shall not be affected by the genuineness, validity, regularity or enforceability of the Guaranteed Obligations or any instrument or agreement evidencing any Guaranteed Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent of any collateral therefor, or by any fact or circumstance relating to the Guaranteed Obligations which might otherwise constitute a defense to the obligations of the Guarantors, or any of them, under this Guaranty, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing.



## 10.02 Rights of Lenders.

Each Guarantor consents and agrees that the Credit Parties may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (a) amend, extend, renew, compromise, discharge, accelerate or otherwise change the time for payment or the terms of the Guaranteed Obligations or any part thereof; (b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this Guaranty or any Guaranteed Obligations; (c) apply such security and direct the order or manner of sale thereof as the Administrative Agent, the L/C Issuers and the Lenders in their sole discretion may determine; and (d) release or substitute one or more of any endorsers or other guarantors of any of the Guaranteed Obligations. Without limiting the generality of the foregoing, each Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of such Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of such Guarantor.

## 10.03 Certain Waivers.

Each Guarantor waives (a) any defense arising by reason of any disability or other defense of the Borrowers or any other guarantor, or the cessation from any cause whatsoever (including any act or omission of any Credit Party) of the liability of the Borrowers or any other Loan Party; (b) any defense based on any claim that such Guarantor’s obligations exceed or are more burdensome than those of the Borrowers or any other Loan Party; (c) the benefit of any statute of limitations affecting any Guarantor’s liability hereunder; (d) any right to proceed against the Borrowers or any other Loan Party, proceed against or exhaust any security for the Guaranteed Obligations, or pursue any other remedy in the power of any Credit Party whatsoever; (e) any benefit of and any right to participate in any security now or hereafter held by any Credit Party; and (f) to the fullest extent permitted by law, any and all other defenses or benefits that may be derived from or afforded by applicable Law limiting the liability of or exonerating guarantors or sureties other than the occurrence of the Facility Termination Date and the payment in full in cash (or other arrangement satisfactory to the applicable Cash Management Bank or Hedge Bank) of all Additional Obligations to the extent then due and payable. Each Guarantor expressly waives all setoffs and counterclaims and all presentments, demands for payment or performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Guaranteed Obligations, and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Guaranteed Obligations.

## 10.04 Obligations Independent.

The obligations of each Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of the Guaranteed Obligations and the obligations of any other guarantor, and a separate action may be brought against each Guarantor to enforce this Guaranty whether or not the Borrowers or any other person or entity is joined as a party.



## 10.05 Subrogation.

No Guarantor shall exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect to any payments it makes under this Guaranty until all of the Guaranteed Obligations and any amounts payable under this Guaranty have been indefeasibly paid and performed in full and the Revolving Commitments and the Revolving Facility are terminated. If any amounts are paid to a Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust for the benefit of the Credit Parties and shall forthwith be paid to the Credit Parties to reduce the amount of the Guaranteed Obligations, whether matured or unmatured.

## 10.06 Termination; Reinstatement.

This Guaranty is a continuing and irrevocable guaranty of all Guaranteed Obligations now or hereafter existing and shall remain in full force and effect until the Facility Termination Date and the payment in full in cash (or other arrangement satisfactory to the applicable Cash Management Bank or Hedge Bank) of all Additional Obligations to the extent then due and payable. Notwithstanding the foregoing, this Guaranty shall continue in full force and effect or be revived, as the case may be, if any payment by or on behalf of the Borrowers or a Guarantor is made, or any of the Credit Parties exercises its right of setoff, in respect of the Guaranteed Obligations and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any of the Credit Parties in their discretion) to be repaid to a trustee, receiver, examiner or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not the Credit Parties are in possession of or have released this Guaranty and regardless of any prior revocation, rescission, termination or reduction. The obligations of each Guarantor under this Section 10.06 shall survive termination of this Guaranty.

## 10.07 Stay of Acceleration.

If acceleration of the time for payment of any of the Guaranteed Obligations is stayed, in connection with any case commenced by or against a Guarantor or the Borrowers under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by each Guarantor, jointly and severally, immediately upon demand by the Credit Parties.

## 10.08 Condition of Borrowers.

Each Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Borrowers and any other guarantor such information concerning the financial condition, business and operations of the Borrowers and any such other guarantor as such Guarantor requires, and that none of the Credit Parties has any duty, and such Guarantor is not relying on the Credit Parties at any time, to disclose to it any information relating to the business, operations or financial condition of the Borrowers or any other guarantor (each Guarantor waiving any duty on the part of the Credit Parties to disclose such information and any defense relating to the failure to provide the same).



## 10.09 Appointment of Company.

Each of the Loan Parties hereby appoints the Company to act as its agent for all purposes of this Agreement, the other Loan Documents and all other documents and electronic platforms entered into in connection herewith and agrees that (a) the Company may execute such documents and provide such authorizations on behalf of such Loan Parties as the Company deems appropriate in its sole discretion and each Loan Party shall be obligated by all of the terms of any such document and/or authorization executed on its behalf, (b) any notice or communication delivered by the Administrative Agent, an L/C Issuer or a Lender to the Company shall be deemed delivered to each Loan Party and (c) the Administrative Agent, the L/C Issuers or the Lenders may accept, and be permitted to rely on, any document, authorization, instrument or agreement executed by the Company on behalf of each of the Loan Parties.

## 10.10 Right of Contribution.

The Guarantors agree among themselves that, in connection with payments made hereunder, each Guarantor shall have contribution rights against the other Guarantors as permitted under applicable Law.

## 10.11 Keepwell.

Each Loan Party that is a Qualified ECP Guarantor at the time the Guaranty or the grant of a Lien under the Loan Documents, in each case, by any Specified Loan Party becomes effective with respect to any Swap Obligation, hereby jointly and severally, absolutely, unconditionally and irrevocably undertakes to provide such funds or other support to each Specified Loan Party with respect to such Swap Obligation as may be needed by such Specified Loan Party from time to time to honor all of its obligations under the Loan Documents in respect of such Swap Obligation (but, in each case, only up to the maximum amount of such liability that can be hereby incurred without rendering such Qualified ECP Guarantor’s obligations and undertakings under this Article X voidable under applicable Law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations and undertakings of each Qualified ECP Guarantor under this Section 10.11 shall remain in full force and effect until the Guaranteed Obligations have been indefeasibly paid and performed in full. Each Loan Party intends this Section 10.11 to constitute, and this Section 10.11 shall be deemed to constitute, a guarantee of the obligations of, and a “keepwell, support, or other agreement” for the benefit of, each Specified Loan Party for all purposes of the Commodity Exchange Act.

Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including all or a portion of its Revolving Commitment and the Loans (including for purposes of this subsection (b), participations in L/C Obligations and in Swingline Loans) at the time owing to it); provided that any such assignment shall be subject to the following conditions:

## (i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Commitment and/or the Loans at the time owing to it or contemporaneous assignments to related Approved Funds (determined after giving effect to such assignments) that equal at least the amount specified in Section 11.06(b)(i)(B) in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(C) the consent of the L/C Issuers and the Swingline Lender shall be required for any assignment in respect of the Revolving Facility.

(iv) Assignment and Assumption.

The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made (A) to any Borrower or any of the Borrowers’ Affiliates or Subsidiaries, (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), (C) to a natural Person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of a natural person) or (D) any holder of subordinated Indebtedness.

(vi) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Company and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (A) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, any L/C Issuer or



any Lender hereunder (and interest accrued thereon) and (B) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of this Section 11.06(b)(vi), then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

(vii) Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 11.06(c), from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05 and 11.04 with respect to facts and circumstances occurring prior to the effective date of such assignment); provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender. Upon request, the Borrowers (at their expense) shall execute and deliver a Revolving Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.06(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 11.06(d).

(c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrowers (and such agency being solely for tax purposes), shall maintain at the Administrative Agent’s Office, or if the Administrative Agent’s Office is not located in the United States, at such other office of the Administrative Agent that is located within the United States, a copy of each Assignment and Assumption delivered to it (or the equivalent thereof in electronic form) and a register for the recordation of the names and addresses of the Lenders, and the Revolving Commitments of, and principal amounts (and stated interest) of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrowers, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. Any assignment of any Loans or other obligations hereunder shall be effective only upon appropriate entries with respect thereto being made in the Register.



The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

## (d) Participations.

(i) Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to any Person (other than a natural Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of a natural Person, a Defaulting Lender or any Borrower or any of the Borrowers’ Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Revolving Commitment and/or the Loans (including such Lender’s participations in L/C Obligations and/or Swingle Loans) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers, the Administrative Agent, the Lenders and the L/C Issuers shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 11.04(c) without regard to the existence of any participations.

(ii) Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 11.01 that affects such Participant. The Borrowers agree that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 (subject to the requirements and limitations therein, including the requirements under Section 3.01(e), 3.01(f), 3.01(g) and 3.01(h) (it being understood that the documentation required under Section 3.01(e), 3.01(f), 3.01(g) and 3.01(h) shall be delivered to the Lender who sells the participation)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 11.06(b); provided that such Participant (A) agrees to be subject to the provisions of Sections 3.06 and 11.13 as if it were an assignee under Section 11.06(b) and (B) shall not be entitled to receive any greater payment under Sections 3.01 or 3.04, with respect to any participation, than the Lender from whom it acquired the applicable participation would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrowers’ request and expense, to use reasonable efforts to cooperate with the Borrowers to



effectuate the provisions of Section 3.06 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.08 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.13 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Loans or other obligations under the Loan Documents (the "Participant Register"); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103–1(c) of the United States Treasury Regulations or to comply with Section 3.01(g) or 3.01(h). The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Revolving Note or Revolving Notes, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(f) Resignation as L/C Issuer or Swingline Lender after Assignment. Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Revolving Commitment and Revolving Loans pursuant to Section 11.06(b), Bank of America may, (i) upon thirty (30) days' notice to the Company and the Lenders, resign as L/C Issuer and/or (ii) upon thirty (30) days' notice to the Company, resign as Swingline Lender. In the event of any such resignation as L/C Issuer or Swingline Lender, the Company shall be entitled to appoint from among the Lenders a successor L/C Issuer or Swingline Lender hereunder; provided, however, that no failure by the Company to appoint any such successor shall affect the resignation of Bank of America as L/C Issuer or Swingline Lender, as the case may be. If Bank of America resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in



Unreimbursed Amounts pursuant to Section 2.03(c)). If Bank of America resigns as Swingline Lender, it shall retain all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans or fund risk participations in outstanding Swingline Loans pursuant to Section 2.04(c). Upon the appointment of a successor L/C Issuer and/or Swingline Lender, (A) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swingline Lender, as the case may be, and (B) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

(g) [Reserved].

(h) Disqualified Institutions.

(i) No assignment shall be made to any Person that was a Disqualified Institution as of the “Trade Date” on which the applicable Lender entered into a binding agreement to sell and assign all or a portion of its rights and obligations under this Agreement to such Person (unless the Company has consented to such assignment as otherwise contemplated by this Section 11.06, in which case such Person will not be considered a Disqualified Institution for the purpose of such assignment). For the avoidance of doubt, with respect to any assignee that becomes a Disqualified Institution after the applicable Trade Date (including as a result of the delivery of a notice pursuant to, and/or the expiration of the notice period referred to in, the definition of “Disqualified Institution”), such assignee shall not retroactively be considered a Disqualified Institution. Any assignment in violation of this Section 11.06(h)(i) shall not be void, but the other provisions of this Section 11.06(h) shall apply.

(ii) If any assignment is made to any Disqualified Institution without the Company’s prior consent in violation of Section 11.06(h)(i), the Borrowers may, at their effort and the sole expense of the assigning institution, upon notice to the applicable Disqualified Institution and the Administrative Agent, (A) terminate any Revolving Commitment of such Disqualified Institution and repay all obligations of the Borrowers owing to such Disqualified Institution in connection with such Revolving Commitment, and/or (B) require such Disqualified Institution to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in this Section 11.06), all of its interest, rights and obligations under this Agreement and related Loan Documents to an Eligible Assignee that shall assume such obligations at the lesser of (x) the principal amount thereof and (y) the amount that such Disqualified Institution paid to acquire such interests, rights and obligations, in each case plus accrued interest, accrued fees and all other amounts (other than principal amounts)



payable to it hereunder and other the other Loan Documents; provided that such assignment does not conflict with applicable Laws.

(iii) Notwithstanding anything to the contrary contained in this Agreement, Disqualified Institutions (A) will not (x) have the right to receive information, reports or other materials provided to Lenders by the Company, the Administrative Agent or any other Lender, (y) attend or participate in meetings attended by the Lenders and the Administrative Agent, or (z) access any electronic site established for the Lenders or confidential communications from counsel to or financial advisors of the Administrative Agent or the Lenders and (B) (x) for purposes of any consent to any amendment, waiver or modification of, or any action under, and for the purpose of any direction to the Administrative Agent or any Lender to undertake any action (or refrain from taking any action) under this Agreement or any other Loan Document, each Disqualified Institution will be deemed to have consented in the same proportion as the Lenders that are not Disqualified Institutions consented to such matter and (y) for purposes of voting on any plan of reorganization or plan of liquidation pursuant to any Debtor Relief Laws (“Plan of Reorganization”), each Disqualified Institution party hereto hereby agrees (1) not to vote on such Plan of Reorganization, (2) if such Disqualified Institution does vote on such Plan of Reorganization notwithstanding the restriction in the foregoing clause (1), such vote will be deemed not to be in good faith and shall be “designated” pursuant to Section 1126(e) of the Bankruptcy Code (or any similar provision in any other Debtor Relief Laws), and such vote shall not be counted in determining whether the applicable class has accepted or rejected such Plan of Reorganization in accordance with Section 1126(c) of the Bankruptcy Code (or any similar provision in any other Debtor Relief Laws) and (3) not to contest any request by any party for a determination by the Bankruptcy Court (or other applicable court of competent jurisdiction) effectuating the foregoing clause (2).

(iv) The Administrative Agent shall, and the Borrowers hereby expressly authorize the Administrative Agent, to (A) post the list of Disqualified Institutions provided by the Company and any updates thereto from time to time (collectively, the “DQ_List”) on the Platform, including that portion of the Platform that is designated for “public side” Lenders or (B) provide the DQ List to each Lender requesting the same.

## 11.07 Treatment of Certain Information; Confidentiality.

(a) Treatment of Certain Information. Each of the Administrative Agent, the Lenders and the L/C Issuers agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to its Affiliates, auditors and its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent required or requested by any regulatory



authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners) (in which case, such Person agrees to inform the Company promptly thereof prior to such disclosure unless (x) such Person is prohibited from doing so under applicable Law or (y) such disclosure is pursuant to a regulatory audit or exam conducted by bank accountants or any governmental bank regulatory authority exercising examination or regulatory authority), (iii) to the extent required by applicable Laws or regulations or by any subpoena or similar legal process (in which case, such Person agrees to inform the Company promptly thereof prior to such disclosure unless such Person is prohibited from doing so under applicable Law), (iv) to any other party hereto, (v) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section 11.07, to (A) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement or any Eligible Assignee invited to be a Lender pursuant to Section 2.18 or Section 11.01 or (B) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrowers and their obligations, this Agreement or payments hereunder (it being understood that the DQ List may be disclosed to any assignee, or prospective assignee, in reliance on this clause (vi)), (vii) on a confidential basis to (A) the provider of any Platform or other electronic delivery service used by the Administrative Agent, any L/C Issuer and/or the Swingle Lender to deliver Borrower Materials or notices to the Lenders or (B) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers or other market identifiers with respect to the credit facilities provided hereunder, or (viii) with the consent of the Company or to the extent such Information (1) becomes publicly available other than as a result of a breach of this Section 11.07 or (2) becomes available to the Administrative Agent, any Lender, any L/C Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrowers, their Subsidiaries or their attorneys or accountants. For purposes of this Section 11.07, “Information” means all information received from the Company or any Subsidiary relating to the Company or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or any L/C Issuer on a nonconfidential basis prior to disclosure by the Company or any Subsidiary; provided that, in the case of information received from the Company or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 11.07 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. In addition, the Administrative Agent and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry and service providers to



the Administrative Agent and the Lenders in connection with the administration of this Agreement, the other Loan Documents and the Revolving Commitments.

(b) Non-Public Information. Each of the Administrative Agent, the Lenders and the L/C Issuers acknowledges that (i) the Information may include material non-public information concerning a Loan Party or a Subsidiary, as the case may be, (ii) it has developed compliance procedures regarding the use of material non-public information and (iii) it will handle such material non-public information in accordance with applicable Law, including United States federal and state securities Laws.

## 11.08 Right of Setoff.

If an Event of Default shall have occurred and be continuing, each Lender, each L/C Issuer and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, such L/C Issuer or any such Affiliate to or for the credit or the account of the Company or any other Loan Party against any and all of the obligations of the Company or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or such L/C Issuer or their respective Affiliates, irrespective of whether or not such Lender, such L/C Issuer or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Company or such Loan Party may be contingent or unmatured, secured or unsecured, or are owed to a branch, office or Affiliate of such Lender or such L/C Issuer different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender shall exercise any such right of setoff, (a) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.15 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the L/C Issuers and the Lenders, and (b) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Guaranteed Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender, each L/C Issuer and their respective Affiliates under this Section 11.08 are in addition to other rights and remedies (including other rights of setoff) that such Lender, such L/C Issuer or their respective Affiliates may have. Each Lender and each L/C Issuer agrees to notify the Company and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application. Notwithstanding the provisions of this Section 11.08, if at any time any Lender, any L/C Issuer or any of their respective Affiliates maintains one or more deposit accounts for the Company or any other Loan Party into which Medicare and/or Medicaid receivables are deposited, such Person shall waive the right of setoff set forth herein.



## 11.09 Interest Rate Limitation.

Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the "Maximum Rate"). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrowers. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

## 11.10 Counterparts; Integration; Effectiveness.

This Agreement and each of the other Loan Documents may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent or any L/C Issuer, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement or any other Loan Document, or any certificate delivered thereunder, by fax transmission or e-mail transmission (e.g., "pdf" or "tif") shall be effective as delivery of a manually executed counterpart of this Agreement or such other Loan Document or certificate. Without limiting the foregoing, to the extent a manually executed counterpart is not specifically required to be delivered under the terms of any Loan Document, upon the request of any party, such fax transmission or e-mail transmission shall be promptly followed by such manually executed counterpart.

## 11.11 Survival of Representations and Warranties.

All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.



## 11.12 Severability.

If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 11.12, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, the L/C Issuers or the Swingle Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

## 11.13 Replacement of Lenders.

(a) If the Company is entitled to replace a Lender pursuant to the provisions of Section 3.06, or if any Lender is a Defaulting Lender or a Non-Consenting Lender or if any other circumstance exists hereunder that gives the Company the right to replace a Lender as a party hereto, then the Company may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.06), all of its interests, rights (other than its existing rights to payments pursuant to Sections 3.01 and 3.04) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(i) the Company shall have paid (or caused a Designated Foreign Borrower to pay) to the Administrative Agent the assignment fee (if any) specified in Section 11.06(b);

(ii) such Lender shall have received payment of an amount equal to 100% of the outstanding principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Company or applicable Designated Foreign Borrower (in the case of all other amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter;



(iv) such assignment does not conflict with applicable Laws; and

(v) in the case of an assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

(b) A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Company to require such assignment and delegation cease to apply. Each Lender agrees that, if the Company elects to replace such Lender in accordance with this Section 11.13, it shall (subject to the Company’s compliance with the provisions of this Section 11.13) promptly execute and deliver to the Administrative Agent an Assignment and Assumption to evidence the assignment and shall deliver to the Administrative Agent any Revolving Note (if Revolving Notes have been issued in respect of such Lender’s Loans and/or Revolving Commitments) subject to such Assignment and Assumption; provided that the failure of any such Lender to execute an Assignment and Assumption shall not render such assignment invalid and such assignment shall be recorded in the Register.

THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (EXCEPT, AS TO ANY OTHER LOAN DOCUMENT, AS EXPRESSLY SET FORTH THEREIN) AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

(c) WAIVER OF VENUE. THE COMPANY AND EACH OTHER LOAN PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION.

To the extent that the Loan Documents provide support, through a guarantee or otherwise, for any Swap Contract or any other agreement or instrument that is a QFC (such support, “QEC Credit Support”, and each such QFC, a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and

In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

## 11.22 [Reserved].

## 11.23 Judgment Currency.

If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or any other Loan Document in one currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the first currency with such other currency on the Business Day preceding that on which final judgment is given. The obligation of each Loan Party in respect of any such sum due from it to the Administrative Agent or any Lender hereunder or under the other Loan Documents shall, notwithstanding any judgment in a currency (the "Judgment Currency") other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (the "Agreement Currency"), be discharged only to the extent that on the Business Day following receipt by the Administrative Agent or such Lender, as the case may be, of any sum adjudged to be so due in the Judgment Currency, the Administrative Agent or such Lender, as the case may be, may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to the Administrative Agent or any Lender from any Loan Party in the Agreement Currency, such Loan Party agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent or such Lender, as the case may be, against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Administrative Agent or any Lender in such currency, the Administrative Agent or such Lender, as the case may be, agrees to return the amount of any excess to such Loan Party (or to any other Person who may be entitled thereto under applicable Law).
