Additional Borrowings

As of June 30, 2014, Vistaprint N.V. (the “Company”) had loans outstanding under its senior secured revolving credit facility of $273.0 million and under its uncommitted, unsecured line of credit with Santander Bank, N.A. (the “Unsecured Line of Credit”) of $21.2 million. Since June 30, 2014, on a net basis, the Company has borrowed an additional $25.0 million in principal amount under its revolving credit facility and $18.8 million in principal amount under its Unsecured Line of Credit. The Company used the proceeds of these additional borrowings for an acquisition, a minority investment and general corporate purposes.

Change of company name

The Company’s Management Board and Supervisory Board have proposed an amendment to the Company’s articles of association to change the company name from Vistaprint N.V. to Cimpress N.V., with the shareholder vote for such amendment scheduled to occur at the Company’s annual general meeting of shareholders in November 2014. Although Vistaprint currently remains the Company’s largest and most important brand for micro business marketing products and services, in recent years the Company has acquired several other brands that serve the needs of various markets, and there has been increasing divergence between Vistaprint the brand and customer value proposition and Vistaprint the corporation. The Company believes that its capabilities in mass customization constitute a key competitive advantage, relevant across its multiple brands. The Company is seeking to change its corporate name to Cimpress N.V. to reflect and help articulate its strategy and ambition to build the world’s leading mass customization platform that it markets via multiple, differentiated brands, including its current and future acquired brands and the Vistaprint brand.

If the Company’s shareholders approve the proposed amendment, the amendment to its articles of association will be effected shortly after the annual meeting. If the Company’s shareholders approve the proposed amendment, the Company will also change its NASDAQ stock ticker symbol to CMPR, and the Company’s corporate website, including its investor relations site, will move to www.cimpress.com. The Company will continue to use its existing URLs for its customer facing brands, including the Vistaprint brand.

Intent to enter into Amended Credit Facility

The Company intends to enter into an amendment to its Senior Secured Credit Facilities (as defined below), which currently consist of (1) a senior secured term loan facility under which the Company has term loans in an aggregate principal amount of $153.9 million outstanding (the “Term Loan A Facility”) and (2) a senior secured revolving facility providing for revolving loans in an aggregate principal amount of $640.0 million (the “Revolving Facility” and, together with the Term Loan A Facility, the “Senior Secured Credit Facilities”). The Senior Secured Credit Facilities currently mature in February 2018. The proposed amendment to the Company’s Senior Secured Credit Facilities (the “Credit Agreement Amendment”) would, among other items, extend the maturity

date of the Senior Secured Credit Facilities to the date that is five years following the effective date of the Credit Agreement Amendment, and increase (i) the loans outstanding under the Term Loan A Facility by $6.1 million to $160.0 million, which additional borrowings would be used to repay $6.1 million in outstanding principal under the Revolving Facility, and (ii) the commitments outstanding under the Revolving Facility by $50.0 million to up to $690.0 million in aggregate principal amount. In addition, the Credit Agreement Amendment would change certain of the financial covenants under the credit agreement governing the Company’s Senior Secured Credit Facilities, including by (i) amending the Company’s maximum permitted consolidated leverage ratio (calculated as the ratio of its consolidated indebtedness to its consolidated EBITDA for the most recent four-quarter period) to 4.50 to 1.00 as of the end of each quarter and (ii) adding a new covenant that the Company’s senior secured leverage ratio, which is the ratio of its consolidated senior secured indebtedness to its consolidated EBITDA for the most recent four-quarter period, not exceed 3.25 to 1.00 as of the end of each quarter. Additionally, pursuant to the Credit Agreement Amendment, the Company may from time to time, subject to the satisfaction of certain approvals and so long as no default or event of default has occurred and is continuing, increase the loan commitments under the Senior Secured Credit Facilities by up to $250 million by adding new commitments or increasing the commitment of willing lenders. The Company expects that its Unsecured Line of Credit will be reduced from $50.0 million to $25.0 million.
