Capture output or exit status from Start-Process inside Invoke-Command in PowerShell

Question

How do I capture the result and/or output of the executable run inside the Start-Process portion of this Invoke-Command?

Invoke-Command -ComputerName $SvrName -ScriptBlock {
    Param ($arg1, $arg2)
    $process = Start-Process -PassThru -FilePath $arg1 -ArgumentList $arg2;
    $process.WaitForExit();
} -ArgumentList $exePath, $command

I want the rest of the script to stop execution if the executable invoked by Start-Process returns an error.
