FREQUENTLY ASKED QUESTIONS

Bitstream was founded in 1981 as a font foundry and evolved to developing software and applications for the graphic arts and mobile communications industries. Bitstream’s fonts and font technologies enabled device manufacturers and application developers to render the highest-quality text in any language, on any device, at any resolution. Bitstream’s MyFonts brand is one of the world’s leading online providers of fonts to consumers.

Monotype Imaging has acquired Bitstream’s font business, which comprises e-commerce solutions and OEM technologies. Solutions include Bitstream’s popular MyFonts.com website, featuring 89,000 fonts from nearly 900 foundries, and Bitstream’s acclaimed WhatTheFont identification service, in addition to the Bitstream typeface library. OEM assets include Bitstream’s Font Fusion and Bitstream Panorama font rendering and layout technologies, as well as a range of fonts for embedded and mobile environments. Monotype Imaging has also acquired 10 patents, covering areas from OEM technologies to Bitstream’s WhatTheFont application.

Monotype Imaging’s mission is to be the first place to turn for typefaces, technology and expertise that enable the best user experience and ensure brand integrity regardless of device, platform or language. The addition of Bitstream’s font business is expected to enhance Monotype Imaging’s ability to accelerate growth across its customer base, expand the company’s IP and capture emerging opportunities, particularly in Web font services and Monotype Imaging’s Display Imaging business. In addition, the company believes that its global reach and financial strength combined with Bitstream’s renowned MyFonts website and OEM business now position Monotype Imaging to serve broader markets, while continuing to deliver high-quality experiences on any publishing medium, platform or device.

In September of 2010, Bitstream announced that it had hired a financial advisory company to advise Bitstream with respect to business opportunities for enhancing shareholder value. Monotype Imaging’s interest in Bitstream’s font business stemmed from a fundamental passion for type, which is at the center of Monotype Imaging’s expertise. When the opportunity was presented to pursue Bitstream’s font business, Monotype Imaging saw this as natural fit. For example, Bitstream’s approach to serving broad markets by way of new and distinctive typefaces is expected to complement Monotype Imaging’s strength in leveraging its historic, classic type collections and multilingual offering to meet the needs of corporations and brands.

Monotype Imaging believes the acquisition will dovetail effectively with the company’s team, technology and culture.

Monotype Imaging did not acquire Bitstream’s BOLT™ mobile browsing and Pageflex^® variable data publishing technologies. As part of the agreement to acquire Bitstream’s font business, these other businesses were spun out to form a new public company, Marlborough Software Development Holdings.

Monotype Imaging acquired Bitstream’s font business in an all cash merger valued at approximately $50 million, which included adjustments based on the closing net asset value of Bitstream. To fund the acquisition, Monotype Imaging drew $25 million on the company’s revolving line of credit.

Thirteen employees have joined Monotype Imaging from Bitstream’s U.S. operation, in addition to 42 engineers and type designers in Noida, India.

Monotype Imaging believes the acquisition will enhance the company’s e-commerce and Web font businesses through a greater selection of fonts and technology solutions. For example, Monotype Imaging intends to support, promote and grow the MyFonts brand and website, which is the resource of choice for a strong community of loyal customers. Monotype Imaging anticipates that OEMs will also have access to a greater portfolio of solutions, particularly in the company’s Display Imaging business. In addition, resources in India will not only contribute to development and R&D functions but also custom type design, particularly for Indic markets.

Now that the acquisition has closed, Monotype Imaging is beginning to integrate and work with Bitstream’s products, services and personnel. Talent from Bitstream is expected to positively impact Monotype Imaging’s e-commerce and type design and development teams, as well as Display Imaging sales. The company’s development and quality engineering resources have expanded substantially, with the addition of 42 employees in India, who will continue to work from the development facility in Noida.

MyFonts is recognized as one of the top e-commerce font websites in the world. It features the WhatTheFont identification service, which enables people to quickly and easily identify fonts. Unknown fonts are submitted as images, which are then identified by Bitstream or people who use the site. Bitstream cultivated an active creative community, helping to drive exciting, innovative design. The company also delivered an excellent user experience and gave type designers considerable control over the work and business. Monotype Imaging intends to maintain MyFonts.com, with an eye toward supporting and extending the best aspects of MyFonts within the company’s cloud-based offerings.

Bitstream brings to Monotype Imaging highly experienced OEM professionals and a complementary customer base that maps directly into the markets Monotype Imaging serves,

particularly in Display Imaging. The acquisition opens opportunity to expand within Bitstream OEM accounts to provide additional value, while adding depth to Monotype Imaging’s family of OEM products and services.

Monotype Imaging will continue to honor the terms and conditions of all existing agreements for current Bitstream customers.

Additional information about the merger is available on the SEC website by accessing Monotype Imaging’s Form 8-K, which announces the transaction and includes the merger agreement.
