Am not sure that Mr. Seward actually purchased the above mentioned 31,454 shares but instead was granted them for his efforts in obtainning leases that were brought into the company fold, which may mean he didn't pay for them. If however, he paid for them great, no problem with that at all. It would just mean he avoided paying a commission on them and they may be restricted shares instead of free tradeable shares.
Based on the information in the filing, he purchased with his own money.
Had the shares been a grant for services or related to compensation in any way, the transaction code would have been A and not P and generally there would have been a note in the section for Explanation of Responses indicating the situation.
Likewise they are not restricted shares, as restricted shares are specifically indicated as such and labelled explicitly in the Title of Security in Form 4 filings - they would not be indicated as Common Stock.
Here is an example of a filing where the transaction was for Restricted Stock.
