1 Year for ADVANCED DISCUSSIONS is not long at all. We could be waiting longer honestly...but the fact that OM is placed directly in the GOLD RUSH era, I believe we see something sooner than later as all the check boxes are being checked off and it's time to move fast. IMO.

Again - for all the people that do not understand NEGOTIATIONS and ADVANCED DISCUSSIONS, here is a real life example. FALL OF 2016 Discussions began with 4 BP's and the end result of MERGER occurred in APRIL 2018................ Now imagine with almost 20 CDA's for IPIX how much work could be going into day to day for MGMT! All while running trials and doing all the ADMIN work for patents and international DD, etc.... We know we have met with CEO's and top Scientists........of BP's. This stuff takes time but I have feeling with OM and IBD, it's time to hit pay dirt.
GOOD LUCK REAL INVESTORS!

Background of the Merger Agreement

The following chronology summarizes the key meetings and events that led to the signing of the Merger Agreement. The following chronology does not purport to catalogue every conversation among the Board or the representatives of AveXis and other parties.

The Company's management and the Board regularly review the Company's performance and prospects in light of its business and developments in the biotechnology and pharmaceutical industries. These reviews have included consideration, from time to time, of potential partnerships, collaborations and other strategic transactions to enhance stockholder value, including potential sale transactions.

In early 2015, prior to the Company's initial public offering, the Company engaged in discussions with Company A regarding a business combination transaction with Company A. After negotiations, the Company and Company A were not able to reach agreement on the terms of a potential combination and Company A terminated discussions. None of the members of Company management at the time of these discussions have a current relationship with the Company.

Beginning in the fall of 2016, following the Company's release of an update on interim data from its ongoing Phase 1 clinical trial of AVXS-101 for the treatment of SMA Type 1, the Company was contacted by several biotechnology and pharmaceutical companies, including Company B, to discuss the Company's business and potential opportunities for various transactions or collaborations. Over the course of the next year, the Company had general discussions from time to time with Company B and other interested biotechnology and pharmaceutical companies.

On June 21, 2017, Mr. Sean P. Nolan, the Company's President and Chief Executive Officer, met over dinner with the Chief Executive Officer and Chief Operating Officer of Company B. At this dinner, the representatives of Company B expressed an interest in submitting an offer to acquire the Company.

On June 29, 2017, the Company received an unsolicited letter from Company B containing a non-binding proposal to acquire 100% of the Company's equity for $112.00 per share, which offer price consisted of 40% cash and 60% Company B common stock (the "June 29 Proposal"). On June 28, 2017, the last trading day prior to the June 29 Proposal, the closing price for shares of the Company's common stock was $81.69.

On July 7, 2017, the Board, along with representatives of Goldman Sachs & Co. LLC ("Goldman Sachs"), which had been engaged as the Company's financial advisor, and Cravath, Swaine & Moore LLP ("Cravath"), which had been engaged as outside counsel to the Company, met to discuss, among other topics, the June 29 Proposal. At the meeting, a representative of Cravath reviewed with the members of the Board their fiduciary duties and obligations in the context of an unsolicited offer to acquire the Company, as well as other legal matters, and representatives of Goldman Sachs discussed with the Board its preliminary financial analyses of the June 29 Proposal. Representatives of the Company's management reviewed with the Board the Company's key upcoming regulatory and clinical milestones relating to the approval and commercial launch of AVXS-101 and the Board considered the risks to the Company of pursuing a transaction during a critical period in the Company's regulatory review process. At this meeting, the Board discussed with the Company's senior management and the representatives of Goldman Sachs the preliminary financial model for the Company prepared by the Company's management, the Company's prospects generally, AVXS-101 and the Company's pipeline. Following discussion, the Board determined to seek improved terms from Company B as a condition to allowing Company B to conduct due diligence or otherwise further exploring a transaction, including,

13

Table of Contents

among other things, an increase in the offer price, an increase in the cash portion of the consideration and a clear understanding from Company B of the need for closing certainty and the allocation of certain regulatory and clinical risks to Company B at signing.

On July 11, 2017, Mr. Nolan spoke telephonically with representatives of Company B and conveyed the Board's views about the necessary parameters that an offer would be required to include in order for the Board to consider engaging in a transaction with Company B or to permit Company B to conduct due diligence, including an increase in the offer price and agreement in advance on the allocation of regulatory and clinical risks to Company B upon signing of a transaction.

On July 20, 2017, representatives of Company B called Mr. Nolan to deliver a revised proposal to acquire all of the outstanding equity of the Company for $118.00 per share, consisting of $59.00 in cash and a fixed value of $59.00 of Company B common stock (subject to a 10% symmetrical collar), which offer was subsequently delivered to the Company in writing (the "July 20 Proposal"). The July 20 Proposal also stated that Company B was prepared to assume certain clinical and regulatory risks between signing and closing.

On July 21, 2017, the Board, along with representatives of Goldman Sachs and Cravath, met to consider and discuss the July 20 Proposal. The Board determined to seek improved terms from Company B as a condition to permitting Company B to conduct due diligence or otherwise further exploring a transaction. Following the Board meeting, Mr. Nolan spoke telephonically with representatives of Company B and explained that Company B would only be permitted to conduct due diligence if Company B improved its offer, including with respect to price, the consideration mix, the elimination of the collar on the stock portion of the consideration and closing certainty.

On July 24, 2017, Mr. Nolan and representatives of Company B spoke telephonically regarding Company B's perspectives as to how it might improve its offer to acquire the Company. Representatives of Company B emphasized that Company B was prepared to move quickly to execute and consummate a transaction.

On July 25, 2017, Messrs. Nolan and Dee met with representatives of Company B for dinner in Chicago. Company B's CEO stated that Company B would be willing to raise its offer price to $130.00 per share, consisting of 55% cash and 45% Company B common stock, and that the stock portion of the consideration would not be subject to a collar (the "July 25 Proposal").

On July 26, 2017, Mr. Nolan electronically transmitted to representatives of Company B a proposed definition of "material adverse effect" and certain other materials summarizing the Company's position on the allocation of regulatory and clinical risks in a potential transaction and indicated that alignment with Company B on approach with respect to these matters would be necessary in order for the Company to continue discussions with Company B at this stage of the Company's regulatory process. Also on July 26, 2017, the Company received a revised offer letter from Company B confirming the July 25 Proposal in which Company B confirmed that it would agree to bear certain regulatory and clinical risks upon singing of a definitive agreement.

On July 27, 2017, the Board, along with representatives of Goldman Sachs and Cravath, met to consider and discuss the July 25 Proposal. Following the discussion, the Board determined that, in light of Company B's improved offer and indication that it would accept certain key risk allocation and transaction certainty terms, it would permit Company B to conduct limited due diligence to enable it to further improve its offer price as well as to increase the cash portion of the consideration. Following the Board meeting, Mr. Nolan conveyed the Board's decision to a representative of Company B.

On July 28, 2017, Cravath sent a draft confidentiality agreement to Company B's legal counsel, the terms of which were negotiated over the next several days. On July 31, 2017, the Company and Company B executed the confidentiality agreement and the Company provided Company B with access to a virtual data room in order for Company B to perform its due diligence investigation. During the

14

following weeks, Company B conducted its due diligence investigation of the Company and representatives of each of the Company and Company B met to discuss certain diligence items.

On August 9, 2017, the Board held a regularly scheduled meeting at which the Company's management reviewed with the Board the status of discussions with Company B. After considering the impact of the due diligence process and transaction discussions on the Company in light of near-term clinical regulatory milestones, the Board determined to request that Company B provide improved terms by the close of business on August 16, 2017.

On August 15, 2017, representatives of Company B informed Mr. Nolan that Company B would be unable to meet the Board's August 16, 2017 deadline for submission of a revised proposal. Following a discussion with the Board, Mr. Nolan spoke telephonically with representatives of Company B and informed them that the Board had agreed to extend the deadline for Company B to submit its final offer to August 23, 2017.

On August 23, 2017, following several weeks of due diligence, in-person meetings and technical discussions, representatives of Company B informed Mr. Nolan that Company B had determined, in light of, among other things, the strong performance of the Company's common stock, the significant premium that would be required to acquire the Company and the stage of development of AVXS-101, to discontinue its exploration of a transaction. Company B's CEO also informed Mr. Nolan that Company B would continue to monitor the Company's performance and would be prepared to reengage following the Company's upcoming meetings with the U.S. Food and Drug Administration (the "FDA").

On September 29, 2017, the Company announced that the FDA had notified the Company that the Company was permitted to initiate its planned pivotal trial of AVXS-101 in spinal muscular atrophy type 1 using the intravenous formulation produced by the Company's commercial manufacturing process.

On December 5, 2017, representatives of the Company met with the FDA for an end-of-Phase 1 meeting, the purpose of which was to review non-clinical, clinical and Chemistry, Manufacturing and Controls (CMC) data that had been generated by the Company, and to align with the FDA on next steps leading to the Company's Biologics License Application ("BLA") submission.

On December 13, 2017, the Company announced that the FDA had notified the Company that the Company was permitted to initiate its planned phase 1 clinical trial of AVXS-101 in spinal muscular atrophy type 2 using the intrathecal route of administration, using material produced by the Company's commercial manufacturing process.

In December 2017, Dr. Charles Bailey, Novartis's Head of Business Development & Licensing, Neuroscience, contacted Mr. R.A. Session II, the Company's Senior Vice President, Corporate Strategy & Business Development, to make an introduction, and invited Mr. Session to meet at the upcoming JP Morgan Healthcare Conference (the "JPM Conference") in January 2018. Although the two were unable to meet at the JPM Conference, a teleconference was arranged for February 2, 2018 with Dr. Bailey and Neil Johnston, Novartis's Global Head of Business Development & Licensing, participating from Novartis and Mr. Session participating from the Company. Mr. Johnston and Dr. Bailey outlined interest in working together with the Company and noted Novartis's commitment to gene therapy as evidenced by the recent licensing transaction with Spark Therapeutics. Mr. Session stated the Company's commitment to its development program. On February 7, 2018, in an email to Mr. Session, Mr. Johnston conveyed the interest of Dr. Vasant Narasimhan, M.D., Chief Executive Officer of Novartis, to speak with Mr. Nolan. Subsequently, a call between Dr. Narasimhan and Mr. Nolan was scheduled for February 16, 2018.

On January 4, 2018, the Company announced alignment with the FDA on next steps toward BLA submission for AVXS-101 following the receipt of minutes from its end-of-Phase 1 meeting with the

15

Table of Contents

FDA. Following the end-of-Phase 1 meeting and this announcement, the Company received inbound interest from several companies in the biotechnology and pharmaceutical industries regarding a potential strategic transaction with the Company, including Novartis and Company C.

On January 8, 2018, the Company and REGENXBIO Inc. ("REGENXBIO") announced the expansion of their relationship through an amended license agreement for the development and commercialization of treatments for spinal muscular atrophy. The amended license agreement provided for, among other things, the modification of the assignment provision in the parties' original license agreement to permit assignment by the Company without REGENXBIO's consent in the event of a change of control of the Company.

On February 12, 2018, Mr. Nolan and Dr. Brian K. Kaspar, Senior Vice President, Chief Scientific Officer of the Company, met with representatives of Company C over dinner in Rosemont, Illinois, during which the representatives of Company C indicated that Company C had a significant interest in the Company.

On February 13, 2018, the Company engaged Centerview Partners LLC ("Centerview") as a financial advisor to assist the Company to explore potential strategic transactions involving the Company.

On February 16, 2018, Mr. Nolan spoke telephonically with Dr. Narasimhan and Mr. Nigel Sheail, Head of Mergers & Acquisitions and Business Development & Licensing of Novartis. Dr. Narasimhan expressed a strong interest in acquiring the Company and indicated that he had the support of Novartis's chairman to submit a proposal to acquire the Company for $190.00 per share in cash. Mr. Nolan emphasized the Company's intent to continue its focus on its business as a stand-alone company given its upcoming regulatory and clinical milestones but stated that he would provide any proposal made by Novartis to the Board for consideration.

On February 19, 2018, the Company received an offer letter from Novartis containing a preliminary and non-binding proposal to acquire all of the outstanding shares of common stock of the Company for $190.00 per share in cash (the "February 19 Proposal"). The offer letter noted that Novartis was prepared to move quickly to announce and execute a transaction and requested a period of exclusivity to negotiate the terms of a definitive agreement.

On February 22, 2018, the Board held a meeting with members of senior management, representatives of Cravath, and, for portions of the meeting, representatives of Goldman Sachs and Centerview, to discuss the February 19 Proposal and certain other topics. At the meeting, the representatives of Cravath reviewed with the members of the Board their fiduciary duties in the context of an unsolicited offer to acquire the Company and representatives of Goldman Sachs and Centerview reviewed with the Board their respective preliminary financial analyses of Novartis's proposal. The Board discussed its view that the Company needed to maintain its focus on its business and preparation for approval and commercial launch of AVXS-101 and the risks that consideration of a transaction could pose to the Company, including the potential for distraction at a crucial point in the regulatory process and that the potential timing of a transaction could impede the Company's ability to successfully launch AVXS-101. The Board discussed, in particular, the Company's near-term need to begin to hire a sales force to execute the launch of AVXS-101. At this meeting, the Board discussed with senior management the Company's prospects generally and assumptions relating to launch dates and pricing models in respect of AVXS-101 made by senior management. Finally, a representative of Cravath discussed with the Board potential regulatory risks relevant to the Board's consideration of a transaction with Novartis. The Board determined to engage in discussions with Novartis and seek, among other things, an increase in the offer price and a clear understanding and agreement from Novartis of the need for closing certainty and the allocation of certain regulatory, manufacturing and clinical risks to Novartis for the period between signing and closing. The Board also determined to reject Novartis' request for a period of exclusivity. The Board also directed management and

Mr. Nolan also informed Dr. Narasimhan about the importance to the Board of certain key risk allocation and transaction certainty terms, including with respect to Novartis's commitment to obtain regulatory approvals in respect of the transaction, and reiterated the Board's concern that discussions regarding a potential transaction could interfere with the Company's business and its preparation for approval and launch of AVXS-101.
