htaccess 301 redirect help

Hi,
I'm trying to redirect old urls of my old web site to new urls to my new web site.
There ara several urls to redirect and I need to redirect them one to one.
My old url is:

Code:

---

http://www.oldsite.com/index.php?page=old-address

---

And the new url is:

Code:

---

http://www.newsite.com/new-adress

---

I tried this;

Code:

---

RewriteEngine On
RewriteBase /
redirect 301 /index.php?page=old-address http://www.newsite.com/new-adress

---

And this;

Code:

---

RewriteEngine On
RewriteBase /
redirect 301 /index.php%3Fpage=old-address http://www.newsite.com/new-adress

---

but it didn't work. Do you have any idea to help me?

Thanks.
