     WHEREAS, Seller acquired the Shares from GAC by a subscription to capital
pursuant to the terms of a Share Subscription & Redemption Agreement dated

are hereby acknowledged, the parties hereby agree as follows:

     1. Grant of Option to Purchase Shares of the Corporation. Seller hereby
grants to CCSI the right and option (the "Option") to purchase the Shares and

     2. Terms and Conditions. The Option evidenced hereby is subject to the
following terms and conditions:


                                     - 1 -

     Obligations (the "Purchase Price") shall be the sum of (i) One Million
     Dollars plus (ii) interest thereon at the rate of fourteen percent (14%)
     per annum (computed on the basis of the actual number of days elapsed in a
     365 day year) from the date hereof to the date of Closing, payable by
     Seller in cash at Closing; provided however, that the Purchase Price may be
     reduced to One Dollar pursuant to Section 6(g) of the Warrant Agreement,
     dated as of June _________ 2001 (the (the "Adjustable Warrant Agreement"),
     between CCSI and Seller, a copy of which is attached as Exhibit C-2 to the
     Subscription Agreement. The reduction is in recognition that the parties
     have exchanged the Shares for CCSI capital stock under the right of Seller
     to do so, per Section 6 (g) of the Adjustable Warrant Agreement.

          b. Expiration Date. Seller must receive written notice from CCSI on or
     before 5:00 p.m. EDT, on the first (1st) anniversary of the date of this
     Agreement (the "Expiration Date") in order for CCSI to exercise this Option
     (the period from the date hereof through the Expiration Date is referred to
     as the "Option Period"). In the event that written notice is not received
     during the Option Period, this Option will expire, without further action
     by either party, and be of no further force or effect.

          c. Vested; No Change to Shares. This Option shall be immediately
     vested as of the date hereof and shall not be subject to forfeiture,
     restriction or amendment (except as otherwise herein provided), without the
     agreement of CCSI.

          d. Non-transferable. This Option shall not be assignable or
     transferable. This Option shall be exercisable only by CCSI or its
     authorized representative.

     3. Closing.

          a. Closing of the transactions contemplated hereby (the "Closing")
     shall take place at the principal offices of CCSI, or at such other place
     as the parties shall agree. The Closing shall be held on or before the
     thirtieth (30th) day after the date Seller receives notice of exercise from
     CCSI, time being of the essence. At the Closing, Seller shall deliver to

     Section 6 (g) of the Adjustable Warrant Agreement, free and clear of all
     liens and encumbrances, the certificate(s) for the Shares to be sold by
     Seller, in negotiable form, duly endorsed for transfer in favor of CCSI or

     certificate(s) in favor of CCSI. Upon such delivery CCSI, subject to the
     terms and conditions hereof, shall deliver to the Seller, free and clear of
     all liens and encumbrances, the Purchase Price as required under Section 2
     above. As of the Closing and after giving effect to the transaction
     consummated thereby, Seller shall cease to have any right, title or
     interest in or to the Corporation, Labs or their respective assets.


                                     - 2 -


          b. In the event that CCSI shall fail to close as provided in paragraph
     3 a. above, then the Option granted to CCSI shall terminate on 12:01 a.m.
     of the immediately succeeding day after the required Closing Date.

     4. Repayment of Loans/Advances/Capital Contributions to Labs. During the
Option Period, Seller (or some of the members of Seller) may make additional
monies available to Labs, which may be made available as additional capital
contributions, loans, open accounts, or otherwise (the "Advances"). If CCSI
exercises its right to acquire the Shares, it shall cause Labs to repay the
unpaid balance of such Advance, plus interest thereon, as provided below. The
parties agree that the following shall apply to any Advances:

          a. The maximum combined amount of such Advances shall not exceed Three
     Hundred Thousand and no/100ths Dollars ($300,000.00).

          b. During the Option Period, payments of interest are permitted to be
     made with respect to the Advances, so long as a simultaneous payment of
     interest in equal amount is made on the obligations of Labs to the Boeing
     Capital Corporation ("Boeing"). During the Option Period, payments of
     principal are permitted with regard to the Advances, so long as a
     simultaneous payment of principal in equal amount is made on the
     obligations of Labs to Boeing.

          c. The Advances (together with any fees related thereto as
     contemplated by the next succeeding paragraph) shall be repaid by delivery
     of a promissory note of Labs to each member of the Seller who made Advances
     (which note principal shall include both principal and accrued, but unpaid,
     interest, through the date of Closing, together with any fees related
     thereto, as contemplated by the next succeeding paragraph) providing for
     repayment in quarterly installments, with interest at fourteen percent
     (14%) per annum, over a two (2) year period from the date of Closing.

          CCSI acknowledges that normal and customary brokerage fees may be
     incurred by the Corporation or Labs in obtaining additional funding for
     their operations and that the incurrence of such fees shall not be deemed
     in violation of this Agreement, so long as a simultaneous payment of
     principal in equal amount is made on the obligations of Labs to Boeing.
     CCSI acknowledges that the payment to Boeing out of the proceeds, as
     demonstrated on Schedule 2 to the Subscription Agreement, shall be deemed a
     payment on the principal for this purpose, and shall permit a simultaneous
     payment of brokerage fees in the same amount as part of the use of
     proceeds, as listed.

     5. Re-conveyance of the Obligations of the Corporation or Labs. As a
condition of the Subscription Agreement, CCSI assigned to Seller all of CCSI's
right, title and interest in and to "Obligations" (being advances, loans, open
accounts or otherwise) which were due to CCSI or parties related to and
controlled by CCSI from either the Corporation or Labs. Such Obligations will be
maintained in the form and status in which they existed when they were assigned
by CCSI to Seller during the Option Period. In the event that CCSI exercises the
Option contained herein, and satisfies all of its Closing conditions, including,
specifically but not limited to, the conditions in paragraph 4 above, Seller
shall cause such Obligations to be reassigned to CCSI at the Closing, without
representation or warranty other than that Seller's title is the same as was
conveyed to Seller by CCSI, similar in form to that attached to the Subscription



                                     - 3 -


Agreement as Exhibit "A.". If the Option is not exercised, or the Closing does
not occur, all such Obligations shall remain and be the unfettered property of
Seller, to handle as Seller deems appropriate.

     6. Restrictions/Requirements on Seller's Operation of the Corporation and
Labs. The parties acknowledge and agree that Seller owns one hundred percent
(100%) of the issued and outstanding capital stock of the Corporation and,
through it, of Labs. The parties further acknowledge that it is the intention of
the parties that the assets and businesses of the Corporation and of Labs,
because of this Agreement, are intended to be continued in similar form and
fashion. Accordingly, to ensure, to the extent possible, CSSI's rights to
exercise this Option, Seller hereby covenants and agrees (in addition to its
covenants and agreements under Section 7 of the Subscription Agreement) as
follows so long as this Agreement is outstanding:

          a. Disbursements From Corporation or Labs. The Corporation shall not
     make, and Seller shall not permit the Corporation to make, any
     disbursements to or for the benefit of the Seller or any person related to
     Seller until the expiration of the Option Period (as defined above), except
     (i) payment of salaries and/or other remuneration for services rendered in
     reasonable amounts, and (ii) standard fringe benefits available to all
     employees of the Corporation or Labs in place as of the date of this
     Agreement, and (iii) ordinary cost of living increases to items (i) and
     (ii). Under no circumstances shall the Corporation make any disbursements
     to or for the benefit of Seller, or any of its affiliates, whether
     classified as loans, dividends, shareholder draws or for any other purpose.

          b. Books and Records. Upon written notification and cooperation with
     Seller, at any time and from time to time after the date which is three (3)
     months after the date of this Agreement, CCSI or its agents shall be
     permitted access to the books and records maintained at the corporate
     offices of the Corporation. CSSI's agents will be permitted to review the
     corporate record books as well as the accounting ledgers of the Corporation
     and all other relevant and necessary documents to assist CCSI in making a
     fully informed decision whether to exercise the Option. CCSI shall not be
     permitted to remove or otherwise copy any information it reviews unless
     agreed by the parties in writing.

          c. Extraordinary transactions. Neither the Corporation nor Labs shall
     engage in any activity, or incur any debt or obligation, or make any
     payment if such is: (i) outside the ordinary course of business, or (ii)
     not reasonably in the best interest of the Corporation or Labs.

          d. Related Party Transactions. The Corporation shall not engage in any
     transactions or enter into any arrangements with, or contract for any
     services performed by, any person or entity affiliated with or related to
     Seller. Notwithstanding this restriction, the Corporation and Labs shall be
     permitted to receive the Advances in accordance with paragraph 4, and shall
     be permitted to pay any interest thereon during the Option Period only as



                                     - 4 -


     provided in paragraph 4 (b), and shall be permitted to enter into ordinary
     and necessary agreements with persons related to the Seller that are on
     terms no less favorable than are available for unrelated third parties, and
     which are terminable at will.

          e. Sharing of Fitzpatrick's Expenses. In recognition that Seller shall
     engage Brian Fitzpatrick ("Fitzpatrick") to provide services to the
     Corporation or Labs of at least ten (10) hours per week, it is agreed that,
     so long as Fitzpatrick continues to provide services to CCSI and to also
     provide services to the Corporation or Labs of at least ten (10) hours per
     week, the following shall apply:

               i. During the Option Period, the Seller shall cause Labs to
          reimburse CCSI for a portion of Fitzpatrick's salary equal to One
          Hundred Twenty Five Thousand and no/100ths Dollars ($125,000.00) per
          annum, plus associated employment taxes and expenses, payable in
          periodic bi-weekly equal installments.

               ii. In the event that CCSI shall not exercise the Option, but
          Fitzpatrick continues to provide services to Labs after the end of the
          Option Period, then for the next two (2) years after the end of the
          Option Period, Labs shall reimburse CCSI for a portion of
          Fitzpatrick's compensation equal to Fifty Thousand and no/100ths
          Dollars ($50,000.00) per annum, plus any associated employment taxes
          and expenses, payable in periodic bi-weekly equal installments.

               iii. Solely for purposes of this subparagraph e, this Agreement
          shall survive the expiration of the Option Period and shall continue
          until the end of the obligations provided in this subparagraph e.


     7. Representations and Warranties of Seller. Each member of the Seller
group represents and warrants to CCSI as follows:

          a. Stock Ownership. Each member of Seller is the owner, free and clear
     of any liens and encumbrances, of all right, title and interest in and to
     the Shares owned by such member of Seller.

          b. No Outstanding Option to Acquire Interests. There are no options,
     warrants, rights, or interests outstanding that would, upon the passage of
     time or of any other matter or incident, give rise to such right for any
     person or entity to acquire any interest in or to the capital stock of the
     Corporation or to any capital stock of Labs.

          c. Absence of Undisclosed Liabilities. Seller does not know or have
     reasonable grounds to know of any basis for the assertion against the
     Corporation or Labs, as of the date of this Agreement, of any material
     liability of any nature or in any amount not previously disclosed to CCSI,
     or provided in its current financial statements.



                                     - 5 -


          d. Duly Formed/Corporate Authority. Seller, if an entity, is duly
     formed under the laws of the state where it is organized, and, Seller has
     all requisite power and authority to own its property and carry on its
     business as now being conducted, to enter into this Agreement, to perform
     its obligations hereunder and to consummate the transactions contemplated
     hereby, and has all requisite licenses and permits necessary to conduct its
     business.

          e. Binding Obligation; Other Matters. This Agreement has been duly
     executed and delivered by Seller and constitutes the valid and binding
     obligation of Seller enforceable in accordance with its terms, subject as
     to enforcement to bankruptcy, insolvency reorganization, moratorium and
     other similar laws of general applicability relating to or affecting
     creditors' rights generally and subject to general equity principles.

          f. Does Not Violate Other Agreements. Additionally, neither the
     execution of this Agreement by Seller nor its required performance
     hereunder will result in any breach or violation of the terms of any
     agreement to which Seller, the Corporation or Labs is a party or by which
     any of them is bound, or of any final decree, judgment, or order, now in
     effect, of any court or governmental body.

          g. Ownership of the Shares. If the Option is exercised, Seller makes
     no further warranties or representations to CCSI except to warrant and
     represent that each member of the Seller group will be, as of the date of
     Closing, and is the owner, free and clear of any liens and encumbrances, of
     all right, title and interest in and to Shares to be sold by each such
     member.

     8. Representations and Warranties of CCSI. CCSI warrants and represents to
Seller that:

          a. The execution, delivery and performance of this Agreement by CCSI,
     has been duly authorized by all necessary action by CCSI. This Agreement
     has been duly and validly executed by CCSI and represents a valid and

     business.

     9. Indemnification.


                                     - 6 -


          a. Each party hereto (referred to in this paragraph as the
     "Indemnitor") agrees to indemnify and hold the other party (referred to in
     this paragraph as the "Indemnified Person") harmless from any cost,
     expense, liability, damage or loss ("Claims") resulting from breach of the
     warranties and representations of the Indemnitor or action or omission by
     the Indemnitor (its agents, employees, or affiliates) with regard to the
     covenants of this Agreement.

          b. The obligations and liabilities of the Indemnitor with respect to
     Claims shall be subject to the following terms and conditions:

               (i) The Indemnified Person shall give the Indemnitor written
          notice of any such Claims promptly after the Indemnified Person
          receives notice thereof. If such Claim was made by any entity or
          person that is not a party hereto (a "Third Party Claim"), the
          Indemnitor shall undertake the defense thereof by representatives of
          its own choosing.

               (ii) In the event that the Indemnitor, within a reasonable time
          after notice of any such Third Party Claim, fails to defend such Third
          Party Claim, the Indemnified Person will (upon further notice to the
          Indemnitor) have the right but not the obligation to undertake the
          defense, compromise or settlement of such Third Party Claim on behalf
          of and for the account and risk of the Indemnitor, subject to the
          right of the Indemnitor to assume the defense of such Claim at any
          time prior to settlement, compromise or final determination thereof.

               (iii) Notwithstanding anything in this paragraph to the contrary,
          if there is a reasonable probability that a Third Party Claim may
          materially and adversely affect the Indemnified Person, other than as
          a result of money damages or other money payments, the Indemnified
          Person shall have the right, at the cost and expense of the
          Indemnified Person, to defend, compromise or settle such Third Party
          Claim. However, the Indemnified Person shall not, without Indemnitor's
          written consent, settle or compromise any Third Party Claim or consent
          to entry of any judgment which does not include as an unconditional
          term thereof given by the claimant or the plaintiff to the Indemnitor
          a release from all further liability in respect of such Third Party
          Claim.

     10. Confidentiality. Except as may be required by law, each party shall,
and shall cause their affiliates, associates, employees and related parties to,
maintain in strict confidence, and shall not disclose to anyone other than their
employees, attorneys, accountants and agents (who shall be under a similar
obligation of confidentiality), this Agreement, the terms and conditions hereof,
and any information, materials, software, lists, or other facts which are
obtained from a party, and shall make no statement, release, confirmation or
other communication to a third party regarding such matters without the prior
written consent of the other party; provided however, this restriction shall not
apply to (i) information in the public domain; (ii) information in the


                                     - 7 -


possession of a party without restriction as to use or disclosure and not
acquired from the other party or related to this transaction; and (iii)
information obtained from third parties who were lawfully in possession of it
and under no obligation of secrecy with respect thereto.

     11. Miscellaneous.

          a. Survival of Representations. All representations, warranties and
     covenants made by the parties to one another hereunder shall survive the
     Closing.

          b. Notices. All notices, requests, demands and other communications
     required or permitted hereunder shall be in writing and shall be deemed to
     have been duly given when delivered by hand or reputable overnight courier
     service (such as Fed Ex) or when mailed by United States certified
     registered mail, return receipt requested, with postage prepaid to the
     address set forth in the first paragraph of this Agreement or to such other
     address as any party may request in writing prior to the date of mailing of
     such notice.

          c. Costs of Enforcement. In the event either party initiates action to
     enforce its rights hereunder, the substantially prevailing party shall
     recover from the substantially non-prevailing party its reasonable
     expenses, court costs, including taxed and untaxed costs, and reasonable
     attorneys' fees, whether suit be brought or not (jointly referred to as
     "Expenses"). As used herein, Expenses include Expenses incurred in any
     appellate or bankruptcy proceeding. All such Expenses shall bear interest
     at the highest rate allowable under the laws of the State of New York from
     the date the substantially prevailing party pays such Expenses until the
     date the substantially non-prevailing party repays such Expenses. Expenses
     incurred in enforcing this paragraph shall be covered by this paragraph.
     For this purpose, the court is requested by the parties to award actual
     costs and attorneys' fees incurred by the substantially prevailing party,
     it being the intention of the parties that the substantially prevailing
     party is completely reimbursed for all such costs and fees. The parties
     request that inquiry by the court as to the fees and costs shall be limited
     to a review of whether the fees charged and hourly rates for such fees are
     consistent with the fees and hourly rates routinely charged by the
     attorneys for the substantially prevailing party.

          d. Entire Agreement. This Agreement constitutes the entire agreement
     between the parties with respect to the subject matter hereof and it shall
     not be amended or modified except by instrument in writing executed by all
     of the parties.

          e. Waiver or Modification. No waiver or modification of this Agreement
     or of any covenant, condition or limitation herein contained shall be valid
     unless in writing and duly executed by the party to be charged therewith.
     Furthermore, no evidence of any modification or waiver shall be offered or
     received as evidence in any proceeding, arbitration or litigation between
     the parties arising out of or affecting this Agreement or the rights or


                                     - 8 -


     obligations of any party hereunder, unless such waiver or modification is
     in writing, duly executed as aforesaid. The provisions of this paragraph
     may not be waived except as herein set forth.

          f. Cumulative Rights. Unless otherwise provided herein, all rights,
     powers and privileges conferred upon the parties by law, this Agreement or
     otherwise shall be cumulative.

          g. Choice of Law. This Agreement and the performance hereunder and all

     or other proceeding that may be brought arising out of, in connection with,
     or by reason of this Agreement, the laws of the State of New York shall be
     applicable and shall govern to the exclusion of the law of any other forum,
     without regard to the jurisdiction in which the action or special
     proceeding may be instituted. All actions under this Agreement shall be
     taken in a court of competent jurisdiction within New York City and the
     parties hereby waive and agree that they shall not assert that such forum
     is inconvenient.

     successors and legal representatives.

          i. Invalid or Unenforceable Provisions. The invalidity or
     unenforceability of a particular provision of this Agreement shall not
     effect the other provisions hereto, and this Agreement shall be construed
     in all respects as if such invalid or unenforceable provisions were
     omitted, and shall be ineffective only to the extent of such prohibition or
     invalidity without invalidating the remaining provisions of this Agreement.

          j. Time. Time shall be of the essence for all performances hereunder.

          k. No Incidental Beneficiaries. Except as specifically set forth or
     referred to herein, nothing herein expressed or implied is intended or

     other than the parties hereto and their successors any rights or remedies
     under or by reason of this Agreement.

          l. Specific Construction. The language used in this Agreement shall be
     deemed to be in the language chosen by the parties hereto to express their
     mutual intent, and no rule of strict construction shall be applied against
