Don Bailey, President and CEO of Questcor Pharmaceuticals, Inc.

DON BAILEY:

Good afternoon everyone.

As you’ve no doubt heard, today Questcor and Mallinckrodt Pharmaceuticals announced that we’ve reached an agreement to combine the two businesses to form a new, highly diversified, high-growth leader in the specialty pharmaceutical industry.

It’s an exciting transaction and one that I believe represents a significant step forward for Questcor serving not only the long-term best interests of our employees, customers, and shareholders but, most importantly, the thousands of patients who are treated with Acthar.

As you can imagine, it’s been a busy day. But I wanted to make sure that I had a chance to reach out and personally introduce you to Mark Trudeau, President and CEO of Mallinckrodt. I’ve asked him to share a few words about Mallinckrodt and the tremendous growth that we believe our combined company is poised to deliver. Mark?

MARK TRUDEAU:

Thank you, Don, and thanks for the chance to speak directly to your Questcor employees.

As Don said, this is a momentous day for both of our companies. This merger brings together two already-strong, fast-growing specialty pharmaceutical companies and positions us to extend our capabilities as an established global leader in the development and commercialization of specialty therapeutics. We at Mallinckrodt are very excited about this transaction and I wanted to have a chance to tell you directly that I believe strongly that by working together and pooling our talents, we’ll be able to create a truly exceptional company.

We want to capitalize on the achievements that you at Questcor have made to date and support the strong upward trajectory of Acthar that you’ve delivered. I’ve been extremely impressed by all that you’ve done at Questcor, and I’m also intrigued by the unique and positive Questcor culture that Don and others senior Questcor leaders have described. While Questcor commercial operations will continue to function as an independent business unit within Mallinckrodt, we believe that merging with us will provide Acthar with a potential platform for future global growth.

Our newly combined company will have a more diversified product portfolio and greater cash flow, to enable faster and broader development of both Acthar and Synacthen. We’ll have the scale and resources to create a strong platform to deliver sustainable growth, and Acthar will become the leading product in the combined company’s broad portfolio of leading specialty pharmaceutical brands, including EXALGO®, XARTEMIS™ XR and OFIRMEV®, a hospital-based pain asset we just added with our acquisition of Cadence Pharmaceuticals. Don?

DON:

Thanks Mark. Stepping back for just a moment, I want to convey a very personal “Thank You” to the Questcor team. Ever since joining the company, I’ve seen first-hand the incredible hard work and dedication each of you has demonstrated as we built our company into the tremendous success it is today. This merger reflects, and in many ways is a culmination of that effort, and serves as testament to our product quality and, most importantly, the talent and commitment of our employees.

By merging our resources – both people and products – we believe our combined company will achieve significantly accelerated growth. On behalf of our Board and management team, I want to make it clear that we are confident Mallinckrodt is the best partner for us. From our very first discussions, they demonstrated a strong understanding and appreciation of our company, our exceptional Acthar performance to date, and our future potential. Most importantly, in all of our interactions with them, they’ve placed great value on our team’s expertise and the critical nature of the unique medication we provide to patients. Mallinckrodt’s diverse product portfolio and experience in complex, highly specialized areas of the pharmaceutical industry make them a great fit to help drive our business to the next stage of growth.

I’ve also gotten to know Mark, and I’m impressed with his depth of experience in the specialty pharma space and his dedication to growth. Mark has spent his entire career in the Pharmaceutical industry with more than 30 years of experience that includes neuroscience and immunology therapies. Prior to his current role – where he guided the launch of Mallinckrodt as a standalone company – he was President and CEO of Bayer HealthCare Pharmaceuticals. Mark is an excellent leader, and I look forward to continuing to work with him as a member of the combined company’s board of directors. This is an exciting time for us, and I am highly confident about the future.

With that, I’ll turn it back over to Mark.

MARK:

So let me quickly give you some background on Mallinckrodt. While we have a tremendous pharmaceutical heritage of nearly 150 years, in many ways Mallinckrodt is also a young company, having just spun out of Covidien in June of last year. In the nine short months since then, we’ve achieved tremendous growth and made great strides in transforming our business into a high-growth specialty pharmaceutical company. Our stock price has responded as well, gaining 42% in those nine months, reflecting an increase from $44 to $62.52 per share as of Friday’s close.

Driving this growth has been an expansion and diversification of our portfolio —both organically, as with our recent introduction of XARTEMIS XR — and through acquisition. As I mentioned, just last month we announced the close of our acquisition of Cadence Pharmaceuticals, which manufactures OFIRMEV, a high-growth pain product that significantly expanded our ability to serve U.S. hospital customers.

Mallinckrodt has core strengths in the acquisition and management of highly regulated, difficult-to-manage products. We have deep regulatory expertise, and specialized chemistry, formulation and manufacturing capabilities. These unique qualities, along with our keenly focused growth strategy, define our strategic fit with Questcor.

When we close, we expect that Questcor commercial operations will function as a separate business unit within Mallinckrodt’s Specialty Pharmaceuticals segment. The business will be led by Steve Cartt, who will report directly to me. And as Don told you, he and two of Questcor’s independent directors will join our board.

Don and I both believe that one of the main value drivers in this merger is the ability of our combined company to leverage the exceptional talent and expertise of both our teams. As a result, we also expect to add other Questcor executives to Mallinckrodt’s executive leadership team. These will be announced at a later date. Mallinckrodt will continue to be domiciled in Ireland, and we’ll have North American offices in Missouri, California, Maryland and Prince Edward Island.

As with all transactions of this sort, until the merger closes, all things at both companies should continue to operate as they normally do. We will establish a joint team to begin to plan the details of integration and will communicate those details to employees as soon as decisions are reached following close of the transaction. We hope to move quickly and expect the transaction to close sometime during the third quarter of this year. In the meantime, I look forward to meeting all of you in person in the coming months.

This is a landmark day for both of our companies, and I proudly look forward to the opportunity to welcome you to Mallinckrodt.
