Structuring so as to have different shareholdings with equal dividends

[c1223]

The company currently exists with a sole director who owns 100 ordinary shares. A third party is buying into this company and the deal is going to pan out roughly as follows:

Third party initially buys 40% shareholding in the company however is paid 50% dividends
After 3-5 years, the third party can increase their share holding to 50%

What is the best way to structure the company so as to allow this? Two classes of shares each with equal rights, with equal dividends being paid to each class of share even though the share numbers are different?

Thanks

Is there a reason as to why you would want to pay 50% dividend for 40% shareholding?

The working hours will be equal, however the company has been running for a few years so the current owner doesn't want to just "hand over" 50% of the company.
