Setting a Publishing Hyperlink Field Value that has no Value

Question

I am using the Object Model and the Microsoft.SharePoint.Publishing.Fields.LinkFieldValue namespace in an attempt to set the value of a Hyperlink Column on a SharePoint 2007 Publishing Site.

However, if the field has no value prior to my update, I get System.ArgumentNullException when I attempt the assignment.

using Pub = Microsoft.SharePoint.Publishing;

int id = 1;
SPListItem item = SPContext.Current.List.GetItemById(itemId);
if(item.Fields.ContainsField("MyHyperlink"))
{
    Pub.Fields.LinkFieldValue destination = 
        new Pub.Fields.LinkFieldValue("<a href=\"www.google.com\">Link</a>");
    item["MyHyperlink"] = destination; //Null Exception here for item["MyHyperlink"]
    item.SystemUpdate(true);
}
