Hi, I'm really struggling with this question, can you help?

2. XYZ Inc. is expected to pay no dividends for the next 5 years. However, at the end of the sixth year (at time 6), the company is expected to pay a dividend of $1/share. Dividends are expected to grow at 10% per year for the following 9 years (through the end of the 15th year, i.e., time 15), then to grow at 5% every year thereafter (forever). Assume the appropriate discount rate (required return) is 10%.
