They all look restricted to me. Look at that block of words below the cusip number in the upper right hand corner of certificates 1 through 4. I think it is easiest to read on certificate 3 of this link you posted:

It looks to me like it says (in all caps), "The securities represented by this certificate have not been registered under the Securities Act of 1933 as amended, or applicable state securities laws. The securities have been acquired for investment and not with a view toward resale, and may not be offered for sale, sold, transferred or assigned in the absence of an effective registration statement for the securities under the Securities Act of 1933 as amended, or applicable state securities laws. . . ."

I think the difference with the last certificate (for 1,750,000 shares) is that it is stamped (in all caps) "Restricted Stock" on the top of the certificate, and then states in the lower right hand corner (again in all caps), "See legend on reverse side." Presumably the legend mirrors that of the other certificates.
