Amendment to Merger Agreement

As previously announced, on February 20, 2017, Nordson Corporation (“Nordson”), Viking Merger Corp. (“Merger Sub”), a wholly owned subsidiary of Nordson, Vention Medical Holdings, Inc. (“Vention”) and VMHI Rep Services, LLC (“VMHI”), as stockholder representative, entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, Vention will be merged with and into Merger Sub (the “Merger”) effective as of the effective time of the Merger (the “Effective Time”).

On March 30, 2017, Nordson, Merger Sub, Vention and VMHI entered into the First Amendment to Agreement and Plan of Merger (the “Amendment”) pursuant to which the parties agreed, among other things, that the Cash Consideration (as defined in the Merger Agreement) would be increased by $11.5 million and, in connection therewith, that Nordson would not have any obligation to pay to Vention’s stakeholders any tax refunds or credits related to the pre-closing periods and any tax benefits related to the pre-closing periods that are utilized by Nordson after the consummation of the Merger.

The foregoing description of the Amendment is a summary only and is qualified in its entirety by the terms of the Amendment, a copy of which is filed as an exhibit to this Current Report on Form 8-K and is incorporated herein by reference.

Term Loan Agreement

On March 31, 2017, in connection with the closing of the Merger, Nordson established a $705.0 million term loan facility pursuant to the terms of the First Amendment and Joinder to Term Loan Agreement (the “Term Loan Amendment”), dated as of March 31, 2017, by and among Nordson, the lenders party thereto and PNC Bank, National Association, as lender and administrative agent, which amended the single-purpose term loan agreement (as amended by the Term Loan Amendment, the “Term Loan Agreement”), by and among Nordson, the lenders party thereto, PNC Bank, National Association, as lender and administrative agent, the joint lead arrangers and joint bookrunners party thereto, the co-syndication agents party thereto and the co-documentation agents party thereto.

The Term Loan Agreement:

Borrowings under the Term Loan Agreement bear interest at either an alternate base rate or an adjusted LIBOR rate plus, in each case, an applicable margin. Such applicable margin is based on Nordson’s Leverage Ratio (as defined in the Term Loan Agreement). Interest is payable (a) in the case of alternate base rate loans, quarterly, and (b) in the

case of LIBOR rate loans, on the maturity date of the borrowing, or quarterly from the effective date for borrowings exceeding three months.

Borrowings under the Term Loan Agreement are available for use by Nordson for the single purpose of acquiring Vention via the Merger.

The foregoing description of the Term Loan Agreement is a summary only and is qualified in its entirety by the terms of the Term Loan Agreement, a copy of which is filed as an exhibit to this Current Report on Form 8-K and is incorporated herein by reference.

On March 31, 2017, pursuant to the terms of the Merger Agreement, Nordson, Vention and Merger Sub completed the Merger, with Vention merging with and into Merger Sub (the “Merger”) effective as of the Effective Time. As a result of the Merger, Merger Sub ceased to exist and Vention survived as a wholly owned subsidiary of Nordson.

Vention is a leading designer, developer and manufacturer of minimally invasive interventional delivery devices, catheters and advanced components for the global medical technology market. Under the terms of the Merger Agreement, as amended, Nordson acquired Vention, excluding all of the outstanding capital stock of Vention Medical, Inc. (“Vention Medical”), and certain subsidiaries of Vention Medical that were sold to a third party prior to the Effective Time, on a cash-free and debt-free basis for an aggregate purchase price of $716.5 million, subject to certain adjustments (including a customary working capital adjustment), resulting in a transaction with an approximate enterprise value of $705 million.

The foregoing description of the Merger Agreement is a summary only and is qualified in its entirety by the terms of the Merger Agreement, a copy of which is filed as an exhibit to this Current Report on Form 8-K and is incorporated herein by reference.
