2 Bondholder Information

According to clause 7 section 1 para. f) and clause 7 section 5 of the terms of the outstanding CHF 250,000,000, 4.5% bond due 2015 (the «Bonds»), the bondholder representative (Credit Suisse AG) has the right (but no obligation) to either declare the Bonds due and payable or to call a bondholders’ meeting (the «Bondholders’ Meeting») and ask bondholders to vote on declaring the Bonds due and payable, in case Rieter changes its legal and/or commercial structure and such change

is deemed by the bondholder representative (Credit Suisse AG) to have a material effect on Rieter’s capacity to meet its obligations in connection with the Bonds.

In the light of the approved Separation and after consultation with Rieter, Credit Suisse AG has called a Bondholder’s Meeting in order to allow the bondholders to decide whether the Bonds shall be declared due and payable.

2. REASON FOR CONVENING A BONDHOLDERS’ MEETING

If the bondholders decide not to declare the Bonds due and payable at the Bondholders’ Meeting («No» to the default question), the Bonds continue until April 30, 2015 and the bondholders will continue to receive annual interest payments of 4.5% per April 30.

3. IMPLICATIONS OF OUTCOME OF BONDHOLDERS’ MEETING

1. BACKGROUND

At the Annual General Meeting of April 13, 2011, the shareholders of Rieter Holding AG («Rieter») approved the separation of the Automotive Systems Division from Rieter (the «Separation»). The Automotive Systems Division will be separately listed and traded as Autoneum on the SIX Swiss Exchange on or around May 13, 2011. Rieter shares will remain listed on the SIX Swiss Exchange.

The Board of Directors of Rieter is convinced that operating the Textile Systems and the Automotive Systems divisions as legally and financially independent businesses will reap a number of considerable benefits for both businesses and their respective customers and employees, in particular it

will enable the businesses to better position themselves and sharpen their individual investment cases. An important result of being independent will be the higher strategic and operational flexibility of each entity. This will enable Rieter as well as Autoneum to capitalize on further development potential and growth opportunities, e.g. through partnerships or co-operations. The separation is a consequence of Rieter’s long-running development goal to establish the financial independence of both businesses. Already today both divisions are operated as separate businesses with their own management teams and organizations. Making them formally independent is therefore a logical step.

question), the Bonds will be repaid immediately at par together with accrued interest. Such repayment at par might differ from the market price of the Bonds.

The continuation of the Bonds would allow Rieter to maintain greater strategic financial flexibility.

4. OVERVIEW OF RIETER AFTER THE SEPARATION OF AUTONEUM

4.1. Business description and key investment highlights

Rieter (Rieter Group post Separation) is a leading supplier of short-staple fiber spinning machinery and components with the broadest global product offering.

Global supplier… … of spinning machinery and components

Rieter is the world’s only supplier offering both solutions for spinning preparation as well as all four short-staple fiber spinning technologies established in the marketplace.

Rieter has systematically expanded its traditional machine business with technology components and service offerings for short-staple spinning mills and is now one of the world’s largest suppliers in the components segment. This business is less exposed than the machinery business to the market cycles specific to the industry.

Rieter is currently among the leaders on the world market for all its key products in the machinery and components segments. Rieter is a strong brand with a long tradition. Rieter globalized its textile machinery business at an early stage and thus has a sound market position worldwide. In particular, Rieter has in recent years expanded its presence by establishing manufacturing facilities in the large and growing markets of China and India and is developing innovative specific products for such markets.

4.3. Outlook As a leading supplier to the textile machinery, Rieter’s Textile Systems Division participated successfully in the market recovery last year. Order intake and sales rose markedly throughout 2010. Rieter’s Textile Systems Division attained a positive operating profit again.

Further development of the respective markets mainly depends on consumer sentiment in Europe and North America, and on economic growth in the major Asian markets. Factors that can additionally influence business developments also include exchange rate effects and raw-material prices – not to speak of disasters as for example in Japan in March 2011.

Thanks to the order backlog at the beginning of year, and good ongoing demand for textile machinery and components, Rieter expects a substantial sales increase for 2011. Rieter expects a further improvement of operating margin compared with 2010 overall, primarily due to higher volumes both in the textile machinery and components businesses. Rieter plans additional investments to accelerate production plant expansion in Asia and thereby further improve its market positioning in China and India.

Over the cycle, Rieter aims to grow sales by 5%, achieve EBIT ratios of >9% (in peak years >12%), net result ratios of >6% (in peak years >8%). Return on net assets is aimed at >14% in peak years. Capex over the cycle are aimed at 4-5% of corporate output.
