6.            CARRY OPTIONS

6.1          Within thirty (30) days after the Vesting Date, MHC shall provide to MAI a written report concerning the status of the Mining Work on the Property. Such report shall describe the state of completion of the Pilot Plant, if any, the Expenditures reasonably anticipated to be required after the Vesting Date to complete such Pilot Plant and a timetable for the making of such Expenditures. During the one hundred twenty (120) day period following the Vesting Date, MAI shall have the option (the "First Carry Option") to elect to reduce its ownership of Newco from forty-nine percent (49%) to thirty-five percent (35%) as of the Pilot Plant Completion Date and proceed on a carried basis until the Pilot Plant Completion Date. MAI may

exercise such option by giving written notice thereof to MHC during such period. If MAI does not elect the First Carry Option, MAI shall be obligated to contribute forty-nine percent (49%) of all funds necessary  for the operations of Newco on the Property through  the Pilot Plant Completion Date. The parties currently contemplate that during the period between the Vesting Date and the Pilot Plant Completion Date Newco will devote substantially all of its resources to completion of the Pilot Plant as opposed to conducting further Exploration; but the parties recognize that the actual expenditure of funds during such period shall be determined at the time by the Board of Directors of Newco and may differ from that currently contemplated, depending upon circumstances at the time.

6.2          If MAI elects the First Carry Option:

(a)   MAI shall promptly after the Pilot Plant Completion Date transfer to MHC or its designated Affiliate for no additional consideration such number of shares of Newco then owned by MAI as shall increase MHC's (or its Affiliate's) ownership of Newco to sixty-five percent (65%) and shall correspondingly reduce MAI's ownership of Newco to thirty-five percent (35%). Such shares of Newco shall be fully paid, non-assessable, and, when transferred, free and clear of any lien, claim, charge or encumbrance.

(b)   During the period from the Vesting Date until the Pilot Plant Completion Date (the "First No Dilution Period"), the parties shall not permit Newco to issue any additional equity, nor take any other action that would reduce MAI's ownership of Newco to less than thirty-five percent (35%). Nothing in the preceding sentence shall prohibit MAI from transferring any of its shares of Newco in accordance with the provisions of Section 10.2 or 10.4.

(c)    During the First No Dilution Period, MHC shall arrange for Newco to obtain all funds the Board of Directors of Newco shall deem necessary to carry out Mining Work in respect of the Property. Such funds shall be provided in the form of debt financing. MAI acknowledges that such financing may be comprised of bank or private financing, including financing provided by MHC or its Affiliates, and that MHC, in its sole discretion shall determine the amount of such financing and the relative proportions of bank and private financing.  Any financing provided by MHC or its Affiliates to Newco shall be made only on arm's-length terms.

6.3          If MAI does not elect the First Carry Option during the one hundred twenty (120) day period following the Vesting Date, then the First Carry Option shall terminate, MAI and its Affiliates' ownership interest in Newco at the end of such one hundred (120) day period shall be forty-nine percent (49%) and the First No Dilution Period shall not apply.

6.4          Following the Pilot Plant Completion Date, the parties contemplate that the sale of mineral products from the Pilot Plant operation will provide some cash flow to Newco which will be invested in further operations on the Property, but the parties recognize that there can be no guarantee as to the amount, if any, of such cash flow. The parties currently contemplate that

following the Pilot Plant Completion Date, the activities of Newco shall be directed primarily toward construction of a Mine on the Property, but the parties recognize that the Board of Directors of Newco will at such time determine the scope of such activities and that such activities may differ from that currently contemplated and may include additional Exploration, depending upon the circumstances at the time. Both parties contemplate that the first Mine on the Property will be project financed to the maximum extent feasible, minimizing any equity contribution of the parties, and MHC shall cause Newco to use reasonable efforts to seek project financing on commercially acceptable terms to develop such Mine. The parties recognize, however, that there can be no guarantee that Newco will be able to obtain project financing on terms acceptable to it. Within thirty (30) days after the Pilot Plant Completion Date, MHC shall provide to MAI a written report concerning the likelihood of obtaining project financing for construction of such Mine, the Expenditures reasonably anticipated to be required after the Pilot Plant Completion Date to complete such Mine and a time table for the making of such Expenditures. The parties acknowledge that such report shall set forth MHC's good faith estimates at the time and shall not bind MHC or Newco to construct the Mine at the cost, with the financing, or within the timetable set forth in the report. During the one hundred twenty (120) day period following the Pilot Plant Completion Date, MAI shall have the option (the “Second Carry Option”) to elect to reduce its ownership of Newco to fifteen percent (15%) as of the Mine Completion Date and proceed on a carried basis until the Mine Completion Date. MAI may exercise such option by giving written notice thereof to MHC during such one hundred twenty (120) day period and may do so whether or not MAI elected the First Carry Option.

6.5          If MAI elects the Second Carry Option:

(a)   MAI shall promptly after the Mine Completion Date transfer to MHC or its designated Affiliate for no additional consideration such number of shares of Newco then owned by MAI as shall increase MHC's (or its Affiliate's) ownership of Newco to eighty-five percent (85%) and shall correspondingly reduce MAI's ownership of Newco to fifteen percent (15%). Such shares of Newco shall be fully paid, non-assessable, and free and clear of any lien, claim, charge or encumbrance.

(b)   During the period from the Pilot Plant Completion Date until the Mine Completion Date (the "Second No Dilution Period”), the parties shall 0not permit Newco to issue any additional equity, nor take any other action that would reduce MAI's ownership of Newco to less than fifteen percent (15%). Nothing in the preceding sentence shall prohibit MAI from transferring any of its shares of Newco in accordance with the provisions of Section 10.2 or 10.4.

(c)   During the Second No Dilution Period, MHC shall arrange for Newco to obtain all funds the Board of Directors of Newco shall deem necessary to carry out Mining Work in respect of the Property.  Such funds shall be provided in the form of debt financing. MAI acknowledges that such financing may be comprised of bank or private financing, including financing provided by MHC or its Affiliates, and that MHC, in its sole discretion, shall determine the amount of such financing

and the relative proportions of bank and private financing.    Any financing provided by MHC or its Affiliates to Newco shall be made only on arm's-length terms.

6.6   If MAI does not elect the Second Carry Option during the one hundred twenty (120) day period following the Pilot Plant Completion Date, the Second Carry Option shall terminate.

(k)   procure on behalf of Newco and maintain in effect with reputable insurance companies adequate liability insurance (which insurance shall provide coverage to the directors of Newco) to cover the activities of Newco. The costs of such insurance shall be deemed an Expenditure for purposes of this Agreement.

7.1.4          MAI shall have the duties and obligations to:

(a)   keep the Rights and the Property free and clear of all liens, encumbrances, burdens or ownership limitations of any nature whatsoever, arising from the activities, commitments and liabilities of MAI or any Affiliate of MAI;

(b)   not interfere with the Mining Work being performed on or in respect of the Property, or any portion thereof, by MHC or its Affiliates or any of their contractors;

If MAI fails to take any step necessary to keep the Rights in good standing, MHC shall have the right to do so on behalf of MAI, MASA or Newco, as applicable.

7.2           The parties shall cooperate with each other during the Option Period to ensure that the parcels comprising the Property are managed efficiently and the Rights kept in good standing.  Neither party shall take any action during the Option Period to exclude from the Property any portion or parcel of the Property without the consent of the other party, except in accordance with the following procedure. If during the Option Period MHC determines that any particular portion of the Property does not merit further exploratory work, MHC may by written notice to MAI exclude such portion of the Property from this Agreement.  Upon the giving of any such notice to MAI by MHC, MAI shall no longer have any obligation to keep MASA and Newco's rights to explore and/or exploit such portion in good standing and MHC shall no longer have any obligation to reimburse MAI or pay directly any costs relating to keeping such rights in good standing.  If then requested by MAI, MHC and MAI shall cause Newco to transfer all of Newco's rights to such excluded portion to MASA free and clear of any lien or encumbrance, and MHC shall pay all costs to effect such transfer.    MHC shall also perform or secure the performance of all reclamation and environmental rehabilitation work as may be required by Argentine law relating to disturbances caused by the performance of Mining Work on such excluded portion of the Property by MHC (or its Affiliates).

8.            TERMINATION PRIOR TO VESTING

8.1           MHC shall have the right to terminate the Option and this Agreement by giving thirty (30) days' written notice of such termination to MAI.  Upon the effective date of termination, the Option and this Agreement shall be of no further force and effect, except that each party shall be required to satisfy any obligations which shall have accrued under the provisions of this Agreement prior to such date of termination and which have not been satisfied, including but not limited to MHC's obligations under Section 8.3.

8.2           The Option and this Agreement shall terminate if MHC fails to give or be deemed to give MAI (i) the Second Year Election on or before the first anniversary of the date of this Agreement, (ii) the Third Year Election on or before the second anniversary of the date of this Agreement, or (iii) the Notice of Exercise within thirty (30) days following the third anniversary of this Agreement.

8.3           In the event of termination of the Option and this Agreement pursuant to this Article 8, MHC shall:

9.            CONFIDENTIALITY

9.1           All information and data concerning or derived from Mining Work shall be confidential and, except to the extent required by law or by regulation of any securities commission, stock exchange or other regulatory body, shall not be disclosed by any party to any person other than such party's professional advisors.

9.2           The text of any news releases or other public statements which any party desires to make with respect to the Rights, the Property or this Agreement shall be subject to the prior approval of the other party, which approval shall not be unreasonably withheld.

10.            RESTRICTIONS ON TRANSFERS OF SHARES OF NEWCO

10.1          Until the earlier to occur of the Vesting Date and the termination  of this Agreement, neither MAI nor MHC shall directly or indirectly sell, transfer, convey, assign, pledge or grant an option in respect of or grant a right to purchase or in any manner transfer or alienate (each of the foregoing, for purposes of this Article 10, hereinafter referred to as a "transfer") any shares of Newco ("Newco Shares") or any shares or other equity interests in an entity that, at the time of such transfer, owns Newco Shares or rights to acquire Newco Shares, or permit their respective Affiliates to do any of the foregoing, without the prior written consent of the other party, which consent such other party may grant or withhold in its absolute discretion. Notwithstanding the provisions of the foregoing sentence, the following transfers shall not be restricted and shall not require the consent of the other party: (i) a transfer that does not materially change the beneficial ownership of the Newco Shares or rights to purchase Newco Shares; (ii) a transfer of shares or other equity interests in an entity that owns Newco Shares or rights to purchase Newco Shares if such transfer (or any series of related transfers) does not result in a change in control of such entity; or (iii) transfers of shares of MAI. A bona fide pledge of shares or other equity interests in an entity that owns Newco Shares or rights to purchase Newco Shares shall not be deemed to cause a change in control of such entity provided

that the terms of such pledge do not permit the exercise of voting or other powers of the owner of the pledged interests except upon default and foreclosure; however, a foreclosure under such pledge (or any similar action under such pledge that has the effect of changing control of such entity) shall be deemed a transfer. If either party shall transfer shares or other equity interests of an entity that owns Newco Shares or rights to purchase Newco Shares in violation of this Article 10, the other party shall, by written notice given not less than ninety days following notice to it of such transfer, have the right to purchase from such entity (or any transferee of Newco Shares from such entity) all, but not less than all, of the Newco Shares and/or rights to purchase Newco Shares owned by such entity at a price determined using the same procedure as provided in Section 13.3.

10.2          After the Vesting Date, a shareholder of Newco (a "Newco Shareholder") may transfer Newco Shares only as permitted under Section 10.3 or 10.4, or in accordance with the following provisions:

10.2.1       Any Newco Shareholder may propose to transfer all of its Newco Shares, or, with the prior written consent of each other Shareholder, which consent may be withheld in each such other Shareholder's sole discretion, less than all of its Newco Shares, and it will promptly furnish to each other Newco Shareholder written notice of the identity of the proposed transferee, the number of Newco Shares proposed to be transferred, the terms and conditions of the proposed transfer and such facts as reasonably demonstrate the transfer is a bona fide transfer (a "Notice of Proposed Transfer").  (In this Section 10.2, that party which furnishes a Notice of Proposed Transfer is called, with respect to the transfer of Newco Shares proposed therein, the "Seller", and such other Newco Shareholders are called, with respect to such proposed transfer, the "Offeree Shareholders" and each individually, an "Offeree Shareholder"). Any Offeree Shareholder may, within thirty (30) days after its receipt of the Notice of Proposed Transfer, elect to purchase all (but not less than all) the Newco Shares to which the Notice of Proposed Transfer relates, at the same price and upon the same terms and conditions as shall be stated therein.  If more than one Offeree Shareholder elects to purchase such Newco Shares, then each such Offeree Shareholder shall be entitled to, and shall, purchase that proportion of the Newco Shares to which the Notice of Proposed Transfer relates as the number of Newco Shares owned by him or it bears to the total number of Newco Shares owned by all such electing Offeree Shareholders, at the same price and upon the same terms and conditions as shall be stated therein.

10.2.2      The election provided for in Section 10.2.1 shall be made by an Offeree Shareholder by giving to the Seller written notice of such election (the "Notice of Election"). The Notice of Election shall specify a date, not later than thirty (30) days after the date the Notice of Election was given, for the closing of such purchase. The furnishing of a Notice of Election in such form shall bind such Offeree Shareholder to purchase, and the Seller to sell, on the date for the closing so specified, the Newco Shares described in the Notice of Proposed Transfer, on the terms and conditions stated therein.

10.2.3      If the Offeree Shareholders do not, within the time period provided for in this Section 10.2, elect to purchase the Newco Shares to which they are entitled by this Section to elect to purchase, the Seller may, at any time within sixty (60) days after the last day of such time

periods, transfer such Newco Shares to the transferee identified in the Notice of Proposed Transfer, at the same price and upon the same terms and conditions stated in such Notice and upon the further condition that at the time of the transfer of such Newco Shares the transferee shall agree in writing, in form satisfactory to all the Offeree Shareholders, to be bound by the provisions of this Agreement in the same manner as the Seller had been bound. If, at the end of such period, the Shares have not been transferred to the transferee identified in the Notice of Proposed Transfer, the agreements of the Seller not to transfer its Newco Shares shall again apply to any proposed transfer of the Newco Shares referred to in such Notice.

10.3          MAI may transfer Newco Shares to MHC or MHC's designated Affiliate in accordance with the provisions of any of Section 4.3, 6.2 and 6.5.

10.4          The prohibitions of Section 10.2 shall not apply to a transfer of Newco Shares by a Newco Shareholder to an Affiliate of such Newco Shareholder if such Affiliate has furnished to the other parties hereto an undertaking in writing, the performance of which is guaranteed by such Newco Shareholder, in form reasonably satisfactory to the other parties hereto, to be bound by the provisions of this Agreement in the same manner as the transferor of such Newco Shares had been bound.

10.5          MAI and MHC shall each ensure that any Newco Shares directly or indirectly owned by it or its Affiliates shall at all times, subject to compliance with the provisions of Section 10.2, be owned by it or such Affiliates and that, if a change in the controlling ownership of any such Affiliate is contemplated, MAI or MHC, as the case may be, shall transfer any Newco Shares held by such Affiliate to itself or another Affiliate prior to such change; provided, however, that this Section 10.5 shall not apply to a transfer of interests in an entity that is the owner of Newco Shares if such transfer is permitted under Section 10.1.

10.6          The parties shall cause Newco to reflect the foregoing restrictions with appropriate legends on all certificates for its stock and notations in its stock ledger, and shall be entitled to disregard for all purposes any purported transfer in violation of this Section 10.

11.            NEWCO BOARD OF DIRECTORS AFTER VESTING

11.1          Promptly following the Vesting Date and for so long as this Agreement remains in effect, the parties shall vote their Newco Shares and take such other action as may be necessary to procure that the Board of Directors of Newco shall consist of three (3) directors and that, subject to Section 11.2:

(a)   at any time at which either party and its Affiliates own in the aggregate a majority of the Newco Shares two (2) of such directors shall be nominated by such party;

(b)   at any time at which either party and its Affiliates own in the aggregate not less than fifteen percent (15%) of the Newco Shares, one (1) of such directors shall be nominated by such party; and

(c)   in all other events, the directors of Newco shall be elected or appointed as provided in Newco's articles of incorporation and bylaws.

11.2          Promptly following the Vesting Date, the parties shall take such action as shall be necessary to amend the by-laws of Newco to (i) fix the Board of Directors at three (3) members, (ii) to remove those provisions of the articles that were contained or inserted therein for the purpose of reflecting the provisions of Section 3.2 and 3.4, and (iii) make such other amendments as the parties shall then deem appropriate to reflect faithfully the terms of this Agreement.

11.3          So long as each party is entitled to nominate at least one director of Newco, the Board of Directors of Newco shall meet at least once every calendar quarter. In lieu of any such meeting, MEC or MAI may request that representatives of each party meet at such place, date and time as is mutually agreed (each such meeting an "Owners Meeting'') to discuss and decide such matters as could otherwise be brought before the Board at the Board meeting. At any such Owners Meeting, MHC and MAI shall each have that number of votes as is equal to the number of directors of Newco it is entitled to appoint.  Promptly following any Owners Meeting, MHC and MAI shall cause their nominees on the Board of Newco to adopt the decisions taken at the Owners Meeting.

12.            FINANCING OF NEWCO AFTER VESTING; DIVIDEND POLICY

12.1          If MAI elects the First Carry Option or the Second Carry Option, or both, and a No Dilution Period applies, then during such No Dilution Period Newco shall finance its operations and activities only from debt and its own revenues, if any, in such manner as the Board of Directors of Newco sees fit.  During a No Dilution period, Newco may mortgage its properties and pledge its assets as security for any debt financing on such terms as the Board of Directors of Newco sees fit; provided,  that, Newco may not grant a mortgage, pledge or other security interest to secure any debt provided by a Newco Shareholder or Affiliate of a Newco Shareholder without the prior unanimous approval of Newco’s Board of Directors.

12.2          Except as provided in Section 12.1 and Article 6, after the Vesting Date Newco shall finance its operations and activities from such sources as the Board of Directors of Newco sees fit. If the Board determines to raise funds by issuing additional Newco Shares, each Newco Shareholder shall have the preemptive right to subscribe and pay for its pro rata share of such additional Newco Shares on the same terms and conditions as each other Newco Shareholder. If Newco shall determine to offer Newco Shares for sale, it shall give notice (the "Company's Notice") to each Shareholder. The Company's Notice shall set forth a description of the Newco Shares, the number of shares to be offered and the terms on which such Newco Shares are to be offered. Within 30 days following the effectiveness of the Company's Notice, each Shareholder may give notice to Newco stating the maximum number of shares of such Newco Shares that such Shareholder is willing to purchase upon the terms set forth in the Company's Notice. Newco shall sell to each Shareholder who gave such notice to Newco and each such Shareholder shall purchase from Newco the number of Shares specified in such Shareholder's notice; provided, however, that if the total number of Newco Shares subscribed for by the Shareholders exceeds the number offered by Newco, the offered Newco Shares shall be allocated in

accordance with the Shareholders' percentage ownership of outstanding Newco Shares prior to such sale.  In addition to the aforementioned procedure, the parties shall also comply with the procedure established in the Argentine Company Law No. 19,550, as amended from time to time.

12.3          If a No Dilution Period does not apply and Newco proposes to borrow funds from a Newco Shareholder or Affiliate thereof, prior to accepting any such loan Newco shall offer each other Newco Shareholder (or its designated Affiliate) the right to participate in such loan, pro rata to its shareholding in Newco, on the same terms and conditions.  Each Newco Shareholder must notify Newco whether it wishes to participate in such loan within thirty (30) days after being so offered.

.

12.4          No Newco Shareholder shall be obligated to subscribe and pay for any additional Newco shares, nor lend or invest any additional amount to or in Newco.  If any Newco Shareholder does not subscribe and pay for its pro rata share of any additional Newco Shares offered to it in accordance with Section 12.2 within sixty (60) days after the date of offer by Newco, each other Newco Shareholder shall be entitled, but not obligated, to acquire its pro rata portion of such Newco Shares on the same terms of the original offer.

12.5          It shall be the policy of Newco not to maintain excess distributable cash. Accordingly, after the Mine Completion Date the parties shall, unless the Board of Newco unanimously decides otherwise and subject to applicable law, cause Newco to distribute to its shareholders on a semi-annual basis all cash not reasonably needed by Newco for operations, maintenance, taxes, debt service, working capital, exploration programs within the Property, reinvestment or expansion of any existing mine or the development of any new mine within the Property.  It shall be the policy of Newco to promptly beneficiate and sell all marketable mineral products from any Mine on the Property. Upon unanimous agreement of the Board of Directors of Newco, Newco may issue dividends of refined gold and silver from the Property in lieu of cash. Unless unanimously approved by the Board of Directors of Newco, Newco shall not enter into any futures contracts, forward sales, hedging, derivatives trading or any other similar marketing mechanism in relation to the mineral products produced from the Property.

13.            MANAGEMENT OF NEWCO AFTER VESTING

13.1.           After the Vesting Date, Newco shall not take action with respect to any of the following items unless such item has been approved by the Board of Directors of Newco or at a meeting of the shareholders of Newco, as applicable under the Argentine Company Law:

(a)   adoption of operating and capital budgets for Newco;

(b)   adoption of exploration programs for the Property;

(c)   appointment of the chief executive officer and chief financial officer of Newco;

(d)   appointment of the external auditors of Newco;

(e)   commissioning any bankable feasibility study;

(f)   entering into any project finance agreements or other similar agreements to borrow funds to construct a mine on the Property;

(g)  increase of the corporate capital and/or issuing any equity securities of Newco;

(h)  granting any mortgage, pledge or other security interest with respect to any of the Rights or any assets of Newco; and

(i)   entering into any contract with a Newco Shareholder or Affiliate of a Newco Shareholder.

13.2        After the Vesting Date, and for so long as each of MHC and MAI is entitled to appoint a director of Newco pursuant to Section 11.1, Newco shall not take action with respect to any of the following items unless such item has been unanimously approved by both MAI and MHC (at a shareholders or board meeting) provided that the favorable vote at a board meeting of either party's nominee shall be deemed an approval by that party:

(a)  the sale of all or substantially all of the Rights and the assets of Newco;

(b)  any amendment of the articles of incorporation of Newco that would have an adverse effect on the rights of any particular Shareholder to receive its corresponding share of the profits of Newco, it being agreed that an amendment to increase the share capital of Newco and pursuant to which each shareholder shall have preemptive rights in accordance with Article 12 of this Agreement shall not be subject to this Section 13.2;

(c)  entering into any new line of business not relating to Exploration, Development or Mining of the Property or the sale of mineral products from the Property; and

(d)   acquiring real property or conducting Exploration, Development or Mining outside of the Property, unless the same is reasonably necessary to permit the exploitation of any part of the Property; and

(e)  any merger or other corporate combination involving Newco.

13.3        In the event of any disagreement between a party entitled under this Agreement to appoint a majority of Newco’s directors (the “Majority Owner") and a party entitled hereunder to appoint one director (the "Minority Owner") concerning any act of Newco that requires the unanimous approval of the Board under this Agreement, the Majority Owner shall have the option to buy all, but not less than all, of the Newco Shares owned by the Minority Owner at

"Fair Value", as determined below.  Unless otherwise agreed by the Minority Owner, such purchase shall be made by payment in full in cash at the closing of such purchase.  Such option must be exercised by written notice to the Minority Owner given within thirty (30) days after the meeting of the Board (or the Owners Meeting) at which the Minority Owner or its nominee on the Board of Newco refuses to approve the relevant action favored by the Majority Owner. Upon the giving of such notice, the parties shall determine the Fair Value of the Newco Shares to be purchased hereunder as follows:

13.3.1     Within thirty (30) days after the date of such notice (the "Notice Date"), each of the Majority Owner and the Minority Owner shall provide to the other its initial determination of the Fair Value of the Newco Shares to be sold hereunder.  The parties shall attempt to reach agreement on such Fair Value based upon such exchange of determinations, but if they do not agree upon such Fair Value within sixty (60) days after the Notice Date, then such Fair Value shall be determined by appraisers appointed in accordance with Section 13.3.2 below.

13.3.2    lf appraisers are required pursuant to Section 13.3.1, each party shall select within ninety (90) days of the Notice Date an appraiser, who shall be a banker, accountant or other person familiar with valuing mining enterprises. The two appraisers selected shall jointly select a third appraiser. The three appraisers so chosen shall determine by majority vote the Fair Value of the Newco Shares to be purchased hereunder. In making such determination, the appraisers must select one of the initial determinations of Fair Value exchanged between the Majority Owner and the Minority Owner. The fees and expenses of the appraisers shall be paid by that party whose determination of Fair Value was not selected by the appraisers.

14.           ALTERNATIVE DEVELOPMENT OF ADDITIONAL MINES

14.l         At any time after the third anniversary of the Mine Completion Date, any director of Newco appointed by MAI may present to the Board of Newco a program to develop a portion of the Property not then under development by Newco.
