Exhibit A
Technical Annex

The Structure that performs the Research Activity is Rizzoli Medical Genetics and Rare Orthopaedic Diseases Department and CLIBI Laboratory (Responsible: Dr. Luca Sangiorgi).

All the activities will be conducted by Medical Genetics and Rare Orthopaedic Diseases Department and CLIBI Laboratory personnel (Head/Scientific Responsible: dr. Luca Sangiorgi)

1) INTRODUCTION

The data that will processed and analysed will be included in the Scirntifico Report, that will be sent to Clementia according to this agreement, collected on REM registry.

Multiple Osteochondromas (MO) is an autosomal dominant disease characterized by the formation of multiple cartilage-capped bone tumours (defined osteochondromas, OCs) typically located in the long bones. OCs are rarely present at birth and grow in number and size during childhood, until completed skeletal maturity. The great variability in size and number of lesions reflects the MO clinical heterogeneity which is characterized by pain, abnormal skeletal growth, decreased range of motion, and deformities. The most serious complication is malignant transformation of OCs into secondary peripheral chondrosarcomas (1-5%). Actually, surgery is the only available treatment with several operations in patient lifespan (average 3) and multiple x-ray is the method of choice in patient monitoring.

MO is mostly caused by heterozygous mutations in the heparan sulfate (HS)-synthesizing enzymes EXT1 or EXT2, implicated in the control of cartilage growth during endochondral ossification; they catalyse polymerization of heparan sulfate glycosaminoglycans (HSGAGs) chains, which are covalently linked to core proteins, thus forming proteoglycans. Even if some EXT mutations are reported to lead to active enzyme isoforms, they are supposed to modify the activity of HS polymerases thus leading to the production of HS chains different from wild-type status; unfortunately, these observations have never been demonstrated in MO patients and the biochemical effect of specific EXT 1/2 mutations is currently unknown.

As known, MO is characterized by a wide clinical intra- and inter-familial variability, currently unexplained at molecular level. Since various genotype-phenotype correlation studies failed to identify specific associations between EXT mutations and clinical manifestations. it is likely that secondary factors influence survival and growth of the lesions.

Since EXT mutations cannot explain all MO genetic aetiology and OC growth is extremely variable in site, size and number, we decided to collect structured data in a Registry in order to promote more productive genotype-phenotype correlation, to study MO epidemiology and natural history and to provide our data analyses for researches and studies.

As a matter of fact. a Disease Registry is a collection of personal, clinical, genetic data of patients.

Many definitions are available for registry. The US Agency for Healthcare Research and Quality define a Registry as “an organized system that uses observational study methods to

collect uniform data (clinical and other) to evaluate specified outcomes for a population defined by a particular disease, condition, or exposure, and that serves one or more predetermined scientific, clinical or policy purposes” and WHO described in 1974 it as “a file of documents containing uniform information about individual persons, collected in a systematic and comprehensive way, in order to serve a pre-determined scientific, clinical or policy purpose”. Many other descriptions can be found internationally, but them all share few main concepts: a) the realization of an organized system, b) denoted by uniformity of data, c) related to a specific disease or precise group of patients d) and finalized to explicit purposes.

More in details a patient registry is a powerful tool composed of interconnected elements that work jointly in order to create an organized collection of information. The word “registry” is composed of two related connotations, the act of register and the entry in a repository and effectively both meanings are involved in a patient registry. The items collected, like clinical data, laboratory test results, anamnestic history and so on , are primary to the scope, but them all are connoted by consistent uniformity both in the nuance of data type composition and in structuring of data themselves.

Starting from 2003 the Medical Genetics and Rare Orthopedic Diseases Department started a collection of data from patients and families affected by Rare Diseases (in particular skeletal dysplasia) and in the subsequent years stared to standardize this data collection and in collaboration with CLIBI Laboratory established the REM (Registry for Mutliple Ostechondromas Disease).

2) DESCRIPTION OF THE RESEARCH ACTIVITIES (preliminary and Analyses)

Research activities (internal to IOR) are composed of multiple steps:

1. a complex selection of case studies includible in this study;

2. according to Clementia specifications and requirements, some multiple data extrapolations from REM to .xls file (or similar format. such as .cvs file );

3. clinical chart, radiological images and surgical folders revaluations;

4. a multistep process of data elaboration, that includes data cleaning, data processing and data analyses.

All these steps will be processed after a preliminary point by point evaluation of required data analyses (listed below)

After the internal research activities, IOR will implement the Scientific Report, as output to be provided to Clementia. The scientific report will not include any personal data that could allow to identify (directly or indirectly) any patient included in the REM.

2.1 AIM

Research activities of this agreement aim to increase the knowledge on MO disease, mainly by an epidemiologic point of view, taking into account underage patients.

Confidential Information omitted and filed separately with the Securities and Exchange Commission.

12

This will be a preliminary evaluation, helpful to comprehend the disease evolution and pathological development of Osteochondromas.

2.2 OBJECT OF THE ANALYSES

The data analyses imply a complex selection of interesting cases, according to Clementia specifications and requirements (see 2.4 Data to analyse). Moreover, REM extrapolated data will be checked, cleaned, processed and at least analysed, following the sequent steps:

· Evaluation of demographic data categorized by age groups

· Evaluation of clinical data categorized by age groups

· Evaluation of radiographical data categorized by age groups

· Disease Evolution studies by age groups

· Number, sites, localizations of OC analyzed by age groups

· Number and type of surgical interventions

· Patients age distribution according to surgical interventions (categorized by age groups)

· Evaluation of interrelations between OC dimension and functional outcomes (pain, deformities, limitations, etc.)

All mentioned steps are epidemiological issues composed of more questions.

2.3 POPULATION UNDER STUDIES

All paediatric patients (<18 age) affected by MO disease.
