Corporate Factors

We are experienced healthcare investors We are a small, highly collaborative team, deeply experienced as both venture investors and operators of healthcare technology companies. Our investment focus is driven by our years of experience growing biopharmaceutical product companies and therapeutic medical device companies. We are focused and highly selective We invest in and work with a limited number of exceptional entrepreneurs. We limit our commitments in the belief that our involvement can increase the probability of success for our portfolio companies and generate greater returns for our investors. Accordingly we choose to limit our capital base. We understand this model well and think that it doesn't scale easily. We lead and participate in rounds We have plenty of experience leading early-stage investments, but we are comfortable co-investing as well. We are willing to participate in financings as small as $1 million, but also have the capacity to invest up to $15 million in a company over time. We like partners Diverse skills and experience, a strong capital base, and good minds all add strength to our companies. We welcome the collaborative participation of experienced venture capital firms and strategic (corporate, academic, philanthropic and individual) investors in our projects. We are well capitalized We have more than $250 million of committed capital to support our companies. Our investors include leading institutions, families and individuals from the U.S. and abroad. Part of this capital is our own, and we try and think of it all that way.

Red Abbey Venture Partners (the “Partnership,” or “Red Abbey”) was formed in December 2003 by Frank A. Bonsal, Jr., Philip Goelet, PhD, Skip Klein and Matt Zuga. The Partnership’s primary investment objective is to generate superior, risk-adjusted returns by investing in high-quality life sciences companies that are developing novel therapeutics and other products based on distinctive technologies. We expect to capitalize on the unprecedented advances in molecular biology, drug discovery and medical treatment that have permanently changed the way that we treat and manage disease. The Partnership has a select group of family offices and individual investors who have committed $50 million to our fund. Red Abbey Venture Partners is creating a portfolio of investments that is diversified by geography, by stage of development, by sector and by therapeutic indication.

Profile and Mission Alloy Ventures is an early-stage venture capital firm. Over the decades of our history, our limited partners have entrusted us with over $1 billion in capital. We are currently investing out of our 5th fund a $368 million limited partnership raised in June 2005. Each year we invest in a small number of entrepreneurial ideas and young companies. We strive to achieve long-term relationships with our entrepreneurs and executives – with the objective of building several successful companies together. This goal requires mutual commitment, respect and trust – values that we try to earn and build-upon every day. Investment approach It’s never too early to approach Alloy Ventures. We have invested as little as $50K to help an entrepreneur develop an idea or write a business plan. However, we typically make initial investments in the range of $1-5 million and reserve additional capital for subsequent financing rounds. We support our companies through each phase of development and actively assist our CEO’s and entrepreneurs in raising follow-on rounds of financing from our extensive network of venture-capital, private-equity, and corporate investors. Investment philosophy The people of Alloy Ventures are problem solvers and opportunity creators. When your growth rate accelerates, a product release date slips, or a competitor threatens, you need partners who will roll up their sleeves and help. We believe that actively involved, industry-savvy investment partners are an invaluable resource for entrepreneurs. We use our experience and connections to help you set strategy, hire key employees, optimize business development opportunities, raise additional capital, and avoid common (and uncommon) mistakes in all phases of your company's growth. Ethics Some of Alloy's partners have been in the venture capital business for more than 25 years — from a time when the industry was smaller, deals were made on a handshake, and you were only as good as your word. We still operate that way. Our values are simple. We minimize politics and egos, treat people fairly, follow through on commitments, and work to solve problems quickly. We expect the same from our entrepreneurs and executives.

Alta is committed to building successful businesses through deep collaborative partnerships with outstanding entrepreneurs. We invest only in those areas where we have specific domain expertise. We are long-term investors and believe that it is critical to be a value-added investor by actively working with portfolio company management teams to help build market-leading companies. We prefer to act as lead investor in the projects that we pursue and, when appropriate, take a board seat as part of our investment. We provide critical strategic, operational and financial advice in this capacity. We also bring to bear insights and advantages from our expanded network of relationships, including assisting our portfolio companies in the recruitment of key executives and board members. Investment Criteria When considering potential investment opportunities, there are several critical characteristics that we seek in a company. Specifically, we look for companies developing unique and proprietary products or technologies, which provide a barrier to competition through technological dominance or a strong intellectual property. We seek companies that target large, compelling market opportunities and entrepreneurial teams driven to succeed.

Altos has helped entrepreneurs build companies since 1996. Starting with initial funding of thirty million, we now manage more than a quarter billion dollars of capital on behalf of leading endowments, financial institutions, fund of funds, and family offices in North America and Asia. We prefer to be the first and lead institutional investor – from raw start-ups to profitable, bootstrapped businesses. In all cases, there must be an opportunity and a mutual commitment to create significant value with limited outside funding. From very modest beginnings, our portfolio companies have grown rapidly to employ thousands of people from around the world and generate more than a billion dollars in annual revenue. We view each engagement as a long term commitment of our time as well as our capital. We invest in only a handful of new opportunities each year and we limit the number of boards each partner can take on. We do not want to be active merely for the sake of being active. However, a disciplined pace and small fund sizes enable us to be ready and able to assist entrepreneurs and their companies. The actions and decisions made at the earliest stages have huge multiplier effects and VCs can have tremendous influence during these critical stages. We contribute not only capital but experienced and patient guidance. We invest in all sectors of the IT industry including software, systems, services and components. Our capital commitments have ranged from $100,000 to over $6 million. For special situations, we can access additional capital, having raised more than $1 billion from co-investors and limited partners.
