AMENDED AND RESTATED SECURITY AGREEMENT

      AMENDED AND RESTATED SECURITY AGREEMENT dated as of February 7, 2006, made
by Graphite Technology Group, Inc., a Delaware corporation (the "Pledgor"), in
favor of BPK Resources, Inc., a Nevada corporation (the "Secured Creditor").

      WHEREAS, the Secured Creditor has agreed to make certain loans
(collectively, the "Loans") to the Pledgor in the aggregate principal amount of
up to One Million Seven Hundred Fifty Thousand Dollars ($1,750,000.00), which is
evidenced by (i) a Promissory Note, dated December 28, 2005, and (ii) a
Promissory Note, dated the date hereof, in each case, by Pledgor to the order of
the Secured Creditor in the aggregate principal amount of the Loans
(collectively, the "Notes"); and

      WHEREAS, it is a condition precedent to the making of the Loans by the
Secured Creditor that the Pledgor shall have executed and delivered to the
Secured Creditor a pledge and security agreement providing for the pledge and
grant to the Secured Creditor of a security interest in the Pledgor's interest
in substantially all of its assets.

      NOW, THEREFORE, in consideration of the premises and the agreements herein
and in order to induce the Secured Creditor to make the Loans, the Pledgor
hereby agrees with the Secured Creditor as follows:

      SECTION 1. Pledge and Grant of Security Interest. As collateral security
for all of the Obligations (as defined in Section 3 hereof), effective as of
January 21, 2006, the Pledgor hereby pledges, assigns and grants to the Secured
Creditor, a continuing security interest in, general lien upon, and right to set
off against the Pledgor's right, title and interest in its machinery and
equipment located in its graphite processing plant at 106 Lakeside Avenue,
Delano, Pennsylvania 18220, including its ACM Milling System (the "Machinery and
Equipment"), and to all of its other assets including all of its Accounts,
Goods, Inventory, General Intangibles, Intellectual Property, Products and
Proceeds, as those terms are defined in the Uniform Commercial Code for the
Commonwealth of Pennsylvania (the "Pledged Collateral").

      SECTION 2. Security for Obligations. The security interest created hereby
in the Pledged Collateral constitutes continuing collateral security for all of
the following obligations, whether now existing or hereafter incurred (the
"Obligations"):

of all amounts owing by it in respect of the Loans and the Notes; and

            (b) the due performance and observance by the Pledgor of all of its
other obligations from time to time existing under this Agreement.

      SECTION 3. Covenants as to the Pledged Collateral. So long as any of the
Obligations shall remain outstanding, the Pledgor will, unless the Secured
Creditor shall otherwise consent in writing, which consent shall not be
unreasonably withheld:

            (a) keep adequate records concerning the Pledged Collateral and
permit the Secured Creditor or any agents or representatives thereof at any
reasonable time and from time to time to examine and make copies of and
abstracts from such records;

            (b) at any time and from time to time, promptly execute and deliver
all further instruments and documents and take all further action that may be
necessary or desirable or that the Secured Creditor may request in order to (i)
perfect and protect the security interest created hereby; (ii) enable the
Secured Creditor to exercise and enforce its rights and remedies hereunder in
respect of the Pledged Collateral; or (iii) otherwise effect the purposes of
this Agreement; and (iv) Secured Creditor is authorized to file financing
statements relating to the Pledged Collateral without Pledgor's signature; and

            (c) not create or suffer to exist any additional lien, security
interest or other charge or encumbrance upon or with respect to any Pledged
Collateral except for the security interest created hereby, the previously
existing liens on the Pledged Collateral and the contemplated $625,000
Commonwealth of Pennsylvania DCED financing.

      SECTION 4. Ownership. Pledgor owns the Pledged Collateral. Except as set
forth in Schedule 4, the Pledged Collateral is free and clear of all liens,
security interests and claims, and Pledgor will keep the Collateral free and
clear from all liens, security interests and claims, other than as contemplated
by Section 3(c) above or those granted to or approved by Secured Creditor.

      SECTION 5. Additional Provisions Concerning the Pledged Collateral.

            (a) The Pledgor hereby authorizes the Secured Creditor to file,
without the signature of the Pledgor where permitted by law, one or more
financing or continuation statements, and amendments thereto, relating to the
Pledged Collateral.

            (b) The Pledgor hereby irrevocably appoints the Secured Creditor the
Pledgor's attorney-in-fact and proxy, with full authority in the place and stead
of the Pledgor and in the name of the Pledgor or otherwise, from time to time in
the Secured Creditor's discretion, to take any action and to execute any
instrument which the Secured Creditor may deem necessary or advisable to
accomplish the purpose of this Agreement.

      (c) The Pledgor represents and warrants to Secured Creditor that: (i) it
has duly obtained all authorizations, consents, rulings, approvals, licenses,
franchises, permits and certificates by or of all third parties to any existing
agreements or instruments by which Pledgor or any of the properties or assets of
Pledgor is or may be bound, which are required for the execution, delivery and
performance of the Notes, this Amended and Restated Security Agreement, or the
Option Agreements, and the consummation of the transactions contemplated hereby
or thereby, as applicable, and of or by all governmental authorities and
non-governmental administrative or regulatory agencies having jurisdiction over
Pledgor, its assets or properties, the Notes, this Amended and Restated Security
Agreement, the Option Agreements or the Pledged Collateral, which are required
for the execution, delivery and performance of the Notes, this Amended and
Restated Security Agreement or the Option Agreements and the consummation of the
transactions contemplated hereby or thereby, as applicable; and (ii) neither the
execution and delivery of the Notes, this Amended and Restated Security
Agreement or the Option Agreements by Graphite nor the performance by Graphite
of its obligations hereunder or thereunder as applicable, will: (A) conflict
with Pledgor's certificate of incorporation or bylaws; (B) violate any statute,
law, ordinance, rule or regulation, applicable to Pledgor or any of the
properties or assets of Pledgor; or (C) violate, breach, be in conflict with or
constitute a default (or an event which, with notice or lapse of time or both,
would constitute a default) under, or permit the termination of any provision
of, or result in the termination of, the acceleration of the maturity of, or the
acceleration of the performance of any obligation of Pledgor, or result in the
creation or imposition of any lien upon any properties, assets or business of
Pledgor under, any contract or any order, judgment or decree to which Pledgor is
a party or by which it or any of its assets or properties is bound or
encumbered.

SECTION 6. Remedies Upon Default. If any Event of Default under the Notes shall
have occurred and be continuing:

            (a) The Secured Creditor may, exercise in respect of the Pledged
Collateral, in addition to other rights and remedies provided for herein or
otherwise available to them, all of the rights and remedies of a secured party
on default as provided under the law of the Commonwealth of Pennsylvania, and
without limiting the generality of the foregoing and without notice except as
specified below, and subject to the previously existing liens on the pledged
collateral, sell the Pledged Collateral or any part thereof in one or more
parcels at public or private sale at such price or prices and on such other
terms as the Secured Creditor may deem commercially reasonable. The Pledgor
agrees that, to the extent notice of sale shall be required by law, at least 10
days' notice to the Pledgor of the time and place of any public sale or the time
after which any private sale is to be made shall constitute reasonable
notification. The Secured Creditor shall not be obligated to make any sale of
Pledged Collateral regardless of notice of sale having been given. The Secured
Creditor may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.

            (b) All cash proceeds received by the Secured Creditor in respect of
any sale of, collection from, or other realization upon, all or any part of the
Pledged Collateral may, in the discretion of the Secured Creditor, be held by
the Secured Creditor as collateral for, and/or then or at any time thereafter
applied in whole or in part by the Secured Creditor against, all or any part of
the Obligations pro rata as to the principal amount of the Loans and the Notes.
Any surplus of such cash or cash proceeds held by the Secured Creditor and
remaining after payment in full of all of the Obligations shall be paid over to
the Pledgor or to such person as may be lawfully entitled to receive such
surplus.

                   (c) In the event that the proceeds of any such sale,
collection or realization are insufficient to pay all amounts to which the
Secured Creditor is legally entitled, the Pledgor shall remain liable for the
deficiency and the Secured Creditor shall retain all rights to collect on such
Obligations provided by applicable law.

      SECTION 7. Notices, Etc. All notices and other communications provided for
hereunder shall be in writing and shall be mailed, telegraphed or delivered, if
to the Pledgor, to it at 106 Lakeside Avenue, Delano, Pennsylvania 18220; and if
to the Secured Creditor, to it at 264 Union Boulevard, Totowa, New Jersey 07152;
or as to any of such parties at such other address as shall be designated by
such parties in a written notice to the other parties hereto complying as to
delivery with the terms of this Section 7. All such notices and other
communications shall be effective (i) if mailed, when deposited in the mails,

      SECTION 8. Miscellaneous.

            (a) No amendment of any provisions of this Agreement shall be
effective unless it is in writing and signed by the Pledgor and the Secured
Creditor, and no waiver of any provision of this Agreement, and no consent to
any departure by the Pledgor therefrom, shall be effective unless it is in
writing and signed by the Secured Creditor, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given.

            (b) No failure on the part of the Secured Creditor to exercise, and
no delay in exercising, any right hereunder shall operate as a waiver thereof;
nor shall any single or partial exercise of any such right preclude any other or
further exercise thereof or the exercise of any other right. The rights and
remedies of the Secured Creditor provided herein are cumulative and are in
addition to, and not exclusive of, any rights or remedies provided by law.

            (c) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability with invalidating the
remaining portions hereof or thereof or affecting the validity or enforceability
of such provision on any other jurisdiction.

            (d) This Agreement shall create a continuing security interest in
the Pledged Collateral and shall: (i) remain in full force and effect until the
payment in full or release of the obligations and (ii) be binding on the Pledgor
and its assigns and shall inure, together with all rights and remedies of the
Secured Creditor hereunder, to the benefit of the Secured Creditor and its
successors, transferees and assigns.

            (e) Upon the satisfaction in full of the Obligations, (i) this
Agreement and the security interest created hereby shall terminate and all
rights to the Pledged Collateral shall revert to the Pledgor, and (ii) the
Secured Creditor will, upon the Pledgor's request and at the Pledgor's expense,
(A) return to the Pledgor such of the Pledged Collateral as shall not have been
sold or otherwise disposed of or applied pursuant to the terms hereof and (B)
execute and deliver to the Pledgor such documents as the Pledgor shall
reasonably request to evidence such termination.

            (f) This Agreement shall be governed by and construed in accordance
with the law of the Commonwealth of Pennsylvania, except as required by
mandatory provisions of law and except to the extent that the validity and
perfection or the perfection and the effect of perfection or non-perfection of
the security interest created hereby, or remedies hereunder, in respect of any
particular Pledged Collateral are governed by the law of a jurisdiction other
than the Commonwealth of Pennsylvania.
