It's pretty straight forward. But as they are complex sentences, I'll break it down to bite size portions to aid you in understanding it.
- The LLC previously raised $9M under a $30M valuation.
- GVSI needs to raise $15M on a best effort basis.
- The LLC has identified private investors that may be willing to invest in GVSI to help raise the $15M.
So once again, the $9M already happened and doesn't count towards this round of fundraising, GVSI has to raise $15M (not $6M) in order to invest in the LLC, and the LLC has identified some potential investors (who invested in the previous $9M round) that may help GS raise the $15M investment.
