ACQUISITION FREQUENTLY ASKED QUESTIONS

GENERAL

1.               What is happening? (Last updated: April 28, 2016)

On April 28, 2016, it was announced publically that Abbott has entered into a definitive agreement with the intent to purchase St. Jude Medical (SJM) for approximately $30 billion (including debt), creating a premier medical device leader with top positions in high-growth cardiovascular markets, including atrial fibrillation, structural heart and heart failure. This planned acquisition, the largest in Abbott’s history, will provide one of the broadest portfolios of devices and an industry-leading pipeline to help healthcare systems provide better care for patients while increasing efficiencies and reducing costs.

2.               Who is Abbott? (Last updated: April 28, 2016)

Abbott was founded more than 125 years ago and has grown into one of the largest diversified global healthcare companies, with approximately 74,000 employees and 2015 annual revenue of $20.4B.

·                   It has four primary focus areas: Nutrition (34%), Medical Devices (25%), Diagnostics (23%) and Established Pharmaceuticals (18%).

·                   About 50% of sales are generated in emerging markets and 50% in developed markets.

·                   About half of the business is direct-to-consumer.

3.               Why did Abbott select St. Jude Medical to acquire? (Last updated: April 28, 2016)

Abbott recognizes SJM’s industry-leading presence and believes the combination of our two companies will create a premier medical device leader. The ability to offer a full spectrum of solutions will enable us to better serve our customers who are increasingly looking to do business with companies who can offer meaningful breadth and depth of care solutions and contracting options. Together, our combined organization will have a presence in virtually every segment of the cardiovascular care continuum, as well as neuromodulation, holding market leading positions in many high-growth segments.

4.               How does St. Jude Medical complement Abbott’s existing business/portfolio? (Last updated: April 28, 2016)

SJM is highly complementary to Abbott’s business, combining Abbott’s leading positions in coronary intervention and transcatheter mitral repair with our electrophysiology (CRM/AF), heart failure, neuromodulation and cardiovascular businesses. We are both focused on improving patient outcomes while lowering the overall costs of healthcare.

Within the medical device space, Abbott holds very strong positions in vascular ($2.8B), diabetes care ($1.1B) and vision solutions ($1.1B). Specifically within the vascular space, their signature products include the Absorb bioabsorbable stent and the MitraClip transcatheter mitral-valve repair device as well as a variety of drug-eluting stents, balloons and catheters. The combined company will have an industry-leading pipeline expected to deliver a steady stream of new medical device products.

5.               What is the process and timeline for the acquisition? (Last updated: April 28, 2016)

In addition to the approval of the shareholders of SJM, there are certain regulatory approvals and closing conditions that must be secured before the transaction can close. The transaction is expected to close in the fourth quarter of 2016. We will keep you updated as we better understand timelines.

6.               What should we expect between now and close? (Last updated: April 28, 2016)

It is important to remember until this transaction is completed, both Abbott and SJM are two independent, publicly-traded companies and must continue to operate that way. When there is new information to share, we will do so as quickly as possible. In the meantime, functional area leaders will be holding employee meetings to discuss what is known at this point and to answer your questions as best we can. All information and updates will be housed on SJM Central, Keyword: Abbott.

INTEGRATION PROCESS

integration of the two businesses, leveraging the capabilities and strengths of both organizations. Once the team is formed, there will be a joint integration kick-off meeting to officially begin the planning process. We expect this kick-off meeting to be held within the next 4-6 weeks. The team will initially focus on steps and activities needed to ensure a successful close of the transaction. Employees should not plan any transition activities unless directed by the integration team. As plans progress, information will be shared as appropriate. It is important to remember that the integration planning effort will be managed by a group of functional leaders from both companies to minimize distraction and to allow the main businesses to continue unencumbered. For both companies, it remains “business as usual.” Employees should stay focused on their work and on delivering on their current commitments.

18.        Will there be job eliminations or changes in job positions/responsibilities? (Last updated: April 28, 2016)

Both Abbott and SJM continually assess staffing levels and make appropriate business decisions based on workforce and operational efficiencies. Integration teams, along with management from both Abbott and SJM will work to ensure we have the right resources in the right places. In the event of any future restructuring actions, information will be shared appropriately as soon as available. It will take some time for the integration team to assess where there may be overlap in workload or processes, or where resources may need to be reallocated. Abbott is interested in retaining employees and ensuring that we are able to keep the business focused on delivering on our plans.

19.        NEW! What support would I receive in the event my job would be eliminated? (Last updated: May 12, 2016)

Abbott is focused on retaining employees and ensuring that we are able to keep the business focused on delivering on our plans. It will take some time for the integration teams to assess where there may be overlap in workload or processes, or where resources may need to be reallocated. SJM has programs in place that provide severance benefits for an eligible employee whose position has been eliminated and who has not secured alternate employment with the company. Abbott has agreed to provide severance benefits that are no less favorable than the severance benefits in place for SJM employees as of signing, until at least one year after close or Dec. 31, 2017, whichever is later, subject to any applicable labor agreement.

Severance for employees outside of the United States differs by jurisdiction and you should contact your local HR representative for information on severance benefits applicable to you. Legacy Thoratec employees continue to be eligible for the Thoratec separation benefit plan until 18 months following the close of the Thoratec transaction. Thereafter, legacy Thoratec employees will be covered by the SJM severance plans for similarly situated SJM employees. (The closing of the transaction with Abbott is not considered a “change in control” for purposes of Thoratec benefit plans.)

For all other employees in the United States, severance is generally governed by the terms and conditions of the SJM Severance Plan for Exempt Employees and the SJM Severance Plan for Non-Exempt Employees. Under these plans, eligible employees who experience a qualifying termination are eligible for severance pay, outplacement assistance and a reduced rate on COBRA payments for medical and dental benefits for three months past the month in which termination occurs. You can review these plan documents on SJM Central. Below is a summary of severance pay benefits under the U.S. plans:

U.S. Severance Plan Highlights

·                   For Non-exempt employees: Two weeks of severance pay for each year of service with a maximum of twelve months of severance pay and minimum of one month of severance pay regardless of the length of service.

·                   For Exempt employees:  One month of severance pay for each year of service with a maximum of twelve months of severance pay and minimum of three months of severance pay regardless of the length of service.

·                   For purposes of the plans, a year of service means twelve consecutive months of service and two weeks of severance pay means one pay period. The severance pay amount will be paid in a lump sum generally on the 60th day after termination.

20.        Am I eligible to apply for other positions within Abbott? (Last updated: April 28, 2016)

SJM employees, managers and HR should not proactively reach out to Abbott employees to discuss potential positions, nor conduct exploratory interviews. SJM employees can be considered for Abbott open positions. Abbott employees can be considered for SJM positions. During the interview process, managers and recruiters should avoid competitively sensitive topics and be mindful of their commitments to company confidential information. If a SJM employee is hired by Abbott prior to the close of the transaction, he or she will be considered a new hire and past service at SJM will not count for any service-related benefits at Abbott. The same applies to Abbott employees hired by SJM prior to the close of the transaction.

21.        Is there a chance I might be asked to relocate? (Last updated: April 28, 2016)

It is too early in the process to know what impact, if any, integration will have on our business or facilities. We can tell you that Abbott has hundreds of offices around the world and maintains a global approach to how its 74,000 employees work together.

22.        Should we continue to travel and attend previously scheduled meetings? (Last updated: April 28, 2016)

Yes, please continue to operate our business as usual unless notified otherwise.

23.        UPDATED! Should we continue with various projects in the pipeline? (Last updated: May 12, 2016)

Yes, please continue to operate our business as usual unless notified otherwise. However, if you are working on a project that you think would benefit from being delayed due to the announcement or you are not sure makes sense to continue, escalate it to your functional leadership so the executive leadership team, in partnership with the integration team and legal counsel, can make an informed decision. Between now and the close of the transaction, we remain two separate companies. Integration teams from Abbott and SJM will be formed to guide the transition. Please wait for direction from this team before planning any transition activities.

24.        Should we continue to fill open positions? (Last updated: April 28, 2016)

Yes, please continue to operate our business as usual unless otherwise notified.

25.        What sort of ongoing information/updates should we expect? (Last updated: April 28, 2016)

We understand this is both an exciting and anxious time for employees. Until the transaction is complete, there are limits to the level of integration and communication that we can conduct and we need to continue to operate our businesses independently. Abbott cannot influence or control our business decisions, and we cannot begin to combine any of our business functions with Abbott. There are many details still being worked out and we will share more information as it becomes available. Our objective is to communicate in a direct and timely fashion.

BENEFITS

26.        UPDATED! Will there be changes to my pay and benefits following close? (Last updated: May 12, 2016)

In addition, Abbott has agreed to provide the following, also until at least one year after close or Dec. 31, 2017, whichever is later (employees outside the U.S. should check with their local HR representative regarding any applicable labor agreements):

·                   Employee health and welfare benefits and retirement benefits no less favorable in the aggregate than those in place for SJM employees immediately prior to the closing date.

27.        Will my company service at St. Jude Medical be recognized by Abbott following close? (Last updated: April 28, 2016)

Following the close of the transaction, SJM employees will generally continue to earn company service at Abbott for the SJM benefits in which they participate (e.g., vacation and savings plans) as of the close date. However, service at SJM will not be recognized for certain benefits at Abbott, such as post-retirement benefits or equity programs.

28.        UPDATED! What happens to the St. Jude Medical 2007 Employee Stock Purchase Plan at close? (Last updated: May 12, 2016)

Per the terms of the merger agreement between Abbott and SJM, SJM will continue to offer the SJM 2007 Employee Stock Purchase Plan (ESPP) through the current contribution period only. New employees may not begin participation in the ESPP.

·                   Current participants may not increase their payroll deductions to the ESPP in the current contribution period.

37.        What impact will this have on suppliers and other vendor or industry partners? (Last updated: April 28, 2016)
