 • Launch Formal Channel Program GOAL: Diversify Revenues at higher margins Provide smoothing function to OEM revenues Add potential Professional Services revenues • Move up the Software (SW) Value Chain GOAL: Make SW a material portion of revenue and margin in 3 years More Firmware and Embedded Data Management Services (DMS) Server based DMS ‘on top of’ RAIDCore Standalone Storage related SW • Move into Adjacent Higher Margin Markets GOAL: Diversify Revenues at higher margins Standalone Storage appliance market Unified Storage Market HILL Step 2 Strategy 2010-2012 8 Cloverleaf Addresses All Three Strategic Initiatives |
 Current Markets Served Source: IDC, Gartner Dataquest and Dot Hill estimates 9 • Dot Hill presently serves the entry level and lower mid range SAN disk array markets • Continued growth expected in our core business |
 Target Markets Source: IDC, Gartner Dataquest and Dot Hill estimates 10 • Cloverleaf’s products address a multi-billion dollar storage software market • Most significant growth comes from replication markets, driven by compliance and data retention policies – 24.5% GAGR 2008-2013 • Heterogeneous and unified virtualized storage are key enablers for growth |
 • Mitigates Risk and Cost of In-House Development Projected internal development of 3 years for similar product Allows us to immediately start to compare against CML & FALC offerings • Beyond our Internal 3 Year Software Development Plan All the basics - Snaps, VolCopy, Mirror, Synch/Asynch Rep, Thin & Tiered provisioning But done across any storage vendor – i.e. mix and match And NAS and SAN blend - Supports Unified Storage Solution emerging as new trend • Accelerates TTM for comparable product by ~2 years Accelerates margin growth and Step 2 Transformation • Acquisition of Technology and Technologists Identical philosophy to Chaparral and Ciprico acquisitions • Solid Data Management/Data Recovery Software DHS monitoring Cloverleaf for 3+ years • Allows for Penetration of the Incremental, Standalone Storage Resource Management market Adjacent high margin market served by FALC, DataCore and LSI (StoreAge) Cloverleaf Rationale 11 |
 12 • Very Robust suite of product features Appliance based – or SW only using OEM commercial servers Based on standard off-the-shelf Intel architecture All features support NAS/SAN and any storage array No server based agent SW required Single Pane, common user interface across all storage and services HA/DR support with a pair of nodes Heterogeneous Snaps, VolCopy, Split Mirror, fCDP Heterogeneous Thin provisioning, Automated Tiered Provisioning Heterogeneous Asynchronous and synchronous replication Data migration from any storage array to any storage array Heterogeneous Virtualized storage pooling across physical arrays FC, CIFS/NFS support (iSCSI Q2 2010, FCOE Q4 2010) Support for clustering up to 12 nodes for near linear performance improvements Existing Cloverleaf Products 12 |
 Potential New Products • Near term – 6 to 12 months Standalone storage management appliance based on iSN lite Bundled appliance + Dot Hill storage solutions Data migration appliance • Next 12-24 months Unified NAS/SAN appliance + storage OEM software or bundled channel product • Future Unified and fully integrated modular storage platforms 13 Standalone SAN Bundle Fully Integrated Integrated Software 13 |

 Merger Consideration • Total deal value $12 million, 7.5% employee carve out • $2.5m in cash • Approx $8.78 million in unregistered common stock valued at 30 day average closing stock price of $1.851 • Approx $0.72 million be settled in restricted shares that will vest over two years and issued from Dot Hill ESOP • Merger consideration to be adjusted up or down to reflect 12/31/2009 Net Book value Note: Merger consideration subject to adjustments based on the amount of outstanding liabilities of Cloverleaf as of the closing of the Merger, transaction expenses incurred by Cloverleaf related to the Merger, a net book value balance sheet adjustment based upon the unaudited consolidated balance sheet of Cloverleaf as of December 31, 2009 and escrow provisions. In addition, there may be a post-closing net book value balance sheet adjustment to the consideration, payable in cash and stock, based upon the audited consolidated balance sheet of Cloverleaf as of December 31, 2009. 15 |
 Valuation Considerations • Technology Purchase not for customers and revenue • Internal development of product with similar feature set – estimated 2 to 3x merger consideration with 3-4 year development schedule • Recent comparables of Israeli companies sold with similar products StoreAge – sold for $50 million to LSI Kaysha – sold for $153 million to EMC Cloverleaf acquisition enables technology purchase today at a fraction of the cost of an organic development effort with new products ready for launch in 6-12 months, thus accelerating time to market by two years and significantly 16 |
