4. Risk factors that may affect the Company’s performance Risk factors that may majorly impact the Company’s operations and performance, which the Company has prepared preventive and control measures for such risks, are summarized below. 4.1. Risk factors that may affect the Company’s profits 4.1.1. Risk from projects that the Company invested in via acquisition 4.1.1.1. Risk from rate of return not being as forcast Since the amount of electricity that is produced from biogas and biomass depends on the amount of raw material, if there is insufficient and uncontinuous supply of raw material, it may cause the production fall under the full capacity. Therefore, the Company may not receive income and a rate of return as expected. However, the Company has already studied the sufficiency of raw material supplies around the area of the plant sites and came up with the plan that will enable the Company to foresee the problems that may occur and be able to correct or adjust the operational processes in a timely manner to reduce the effects of this risk. 4.1.1.2. Risk in project management and efficiency of power plants Managing biogas power plants require eligible personnel with knowledge and skills. If the Company cannot recruit and maintain those such experts, the Company might experience inefficiency in managing the projects. However, the Company has a scheme to motivate and retain potential employees as well as provide continuous training, thus maintain the retention and reduce the risk in the management and efficiency of power plants. 4.1.2. Risk associated with subsidiaries operating biomass power plants. 4.1.2.1. The risk of failure to operate on the Scheduled Commercial Operation Date as stipulated in the PPA. Before constructing the biomass power plant, the subsidiary must obtain related permits such as construction permit, permits for factory operation (Ror.Ngo.4 Permit) and must conduct a referendum before submitting for a construction permit etc. The EPC Contractor must also construct the project according to schedule. If the construction is off schedule, production and operations for the PEA would not be done according to the SCOD specified in the PPA resulting in the delay in revenue recognition of the subsidiaries. Therefore, the Company has conducted a study on the process of obtaining such permits, the preparation of required documents, the selection of well-known contractors that have experience and expertise in the construction of power plants and a well planning and monitoring of the progress to ensure that the permit application process and construction process are on schedule. However, the subsidiaries are able to extend SCOD with the PEA, stating the reason and reporting the progress of the project to the PEA, which in this case, is not considered as a breach of the agreement. 4.1.2.2. Risk of capital for the construction of the biomass power plant project If the Company or subsidiaries are not able to find a source of fund for the construction of the biomass power plant project, whether by equity or borrowings, there will be a risk that the project will not be conducted

- 42 -

as planned. However, the Company has already made preliminary negotiations with a financial institution for a Project Finance loan for the power plant project. Moreover, the Company plans to use the proceeds, about 33 million baht, from the Company’s capital increase that the was approved by the Extraordinary General Shareholders Meeting No. 1/2016 on 23 December 2015, and the Company’s operating cash flow to invest in this project. The Company also has planned to operate the size of power plant that fit with the source of funds. Therefore, the Company is positive that the Company will be able to obtain sufficient funds for the biomass power plant project. 4.1.2.3. Risk in project management and efficiency of power plants Managing biomass power plants require eligible personnel with knowledge and skills. If the Company cannot recruit and maintain those such experts, the Company might experience inefficiency in managing the projects. However, the Company has a scheme to motivate and retain potential employees as well as provide continuous training, thus maintain the retention and reduce the risk in the management and efficiency of power plants. 4.1.2.4. Risk from rate of return not being as expected Since the amount of electricity that is produced from biomass depends on the amount of raw material, if there is insufficient and uncontinuous supply of raw material, it may cause the Company in not being about to produce to the full capacity. Therefore, the Company may not receive income and a rate of return as expected. However, the Company has evaluated the amount raw material and has made an agreement with the raw material supplier. Also, the Company has planned to order raw materials in advance according to each plant’s operations, along with close contact with the raw materials suppliers. This will enable the Company to foresee the problems that may occur and be able to correct or modify operational processes in a timely manner to reduce the effects of this risk. 4.2. Risk from unstable income during the year Part of the Company’s revenues is from designing, distributing and installing Power Monitoring and Management Solutions business, in which government agencies are main targets such as CAT Telecom Public Company Limited. These quasi-government or government agencies has a fiscal budget starting in October of each year and they will require certain periods to prepare for procurement and bidding and it also takes about 3 - 6 months to complete the project and collects money. This may cause revenues in each quarter fluctuate seasonally. 4.3. Risk of depending on the telecommunication industry Major shares of the Company’s revenues derived from designing, distributing and installing Power Monitoring and Management Solutions business, in which main target customers are public and private companies in the telecom business. The Company may has a risk of downtrend in the telecom industry. The recession may come from various factors such as government agencies’ investment policy in relation to the telecom systems or change of concession policy for communication systems in the future etc. To prevent such risk of dependency, the Company has expanded its customer base to include other sectors such as hotels, commercial buildings etc. Also, the Company has expanded into the renewal energy business which can generate stable income in each quarter. This will enhance the diversification of of revenues from each sector and lessen the dependency on specific customers.
