Employee Buying Company Shares

Hi, I work for a big media house in Bangalore, our company is unlisted. We have something called 'Credit Society' where employee can avail loan, short term loan, RD and corresponding to number of years in service and duration of monthly contribution to the credit society we are allocated shares. Once in a year we get dividends. Buying more shares is only possible if one avail loan from the 'Credit Society' Where in having more shares, i will be getting better dividends and useful during retirement or moving to another company. My question, Is it good option to buy company shares through loan even though loan is no need by me. Here if the loan amount is 1 lakh, we are allocated 10,000 worth of shares with a option to either payback entire amount or 90,000 through installments. Thanks
