    SERIES
      A SENIOR CONVERTIBLE PREFERRED STOCK

    PURCHASE
      AGREEMENT

    

    THIS
      SERIES A SENIOR CONVERTIBLE PREFERRED STOCK PURCHASE AGREEMENT (this
“Agreement”)
      is
      made as of the 2nd
      day of
      November, 2007, by and between NTR Acquisition Co., a Delaware corporation
      (the
“Company”),
      and
      Occidental Petroleum Investment Co., a California Corporation (“Occidental”).

     

    THE
      PARTIES HEREBY AGREE AS FOLLOWS:

     

    1.
      PURCHASE AND SALE OF STOCK.

     

    1.1
      Sale and Issuance of Series A Preferred Stock.

    

    (a) The
      Company shall adopt and file with the Secretary of State of the State of
      Delaware on or before the Closing (as defined below) a Certificate of
      Designations of Preferred Stock in
      the
      form attached hereto as Exhibit
      A
      (the“Certificate
      of Designations”).

    

    (b) Subject
      to the terms and conditions of this Agreement, Occidental agrees to purchase
      at
      the Closing and the Company agrees to sell and issue to Occidental, at the
      Closing, shares of the Company’s Series A Senior Convertible Preferred Stock,
      par value $0.0001 per share (the “Series
      A Preferred Stock”),
      at a
      purchase price of $1000 per share (the “Liquidation
      Preference Amount”).
      The
      number of shares of Series A Preferred Stock the Company will sell and
      Occidental will purchase at the Closing will equal the quotient of (A) the
      sum
      of (1) $35,000,000 and (2) the principal amount of the Note (as defined below)
      and (3) the Accrued Interest Amount and (B) the Liquidation Preference Amount,
      rounded up to the nearest whole share. 

    

    The
      “Note”
means
      that certain Promissory Note of even date herewith, in the aggregate principal
      amount of up to $3,000,000, between the Company and Occidental, together with
      any Additional Notes (as defined such Promissory Note) that may be delivered
      or
      deemed delivered by the Company thereunder. The “Accrued
      Interest Amount”
is
      the
      amount of interest accrued (and not capitalized) on the Note through the Closing
      date. The Series A Preferred Stock will have the rights, preferences, privileges
      and restrictions set forth in the Certificate of Designations.

     

    1.2
      Closing.

    

    (a)
      Subject to the satisfaction or waiver of each party’s the conditions in
Section 4,
      the
      purchase and sale of the Series A Preferred Stock shall take place at the
      offices of Cleary Gottlieb Steen & Hamilton LLP simultaneously with the
      Closing of the acquisition
      (the “Transaction”),
      directly or indirectly, of all outstanding shares of each class of common stock
      of Kern Oil & Refining Co., a California corporation (“Kern”)
      from
      Casey Co., a California corporation (“Casey”)
      pursuant to that certain Stock Purchase Agreement in substantially the form
      attached as Exhibit
      B
      (“Kern
      Acquisition Agreement”)
      or any
      replacement acquisition by the Company through a merger, capital stock exchange,
      asset acquisition, stock purchase, reorganization or other similar business
      combination of one or more businesses or assets in the energy business
      acceptable to Occidental (“Replacement
      Transaction”),
      or at
      such other time and place as the Company
      and Occidental shall mutually agree, either orally
      or in
      writing (which time and place are designated as the “Closing”).

    

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

     

    (b)
      At
      the Closing, the Company shall deliver to Occidental a certificate representing
      the shares of Series A Preferred
      Stock and Occidental shall (i) pay an amount equal to $35,000,000 by wire
      transfer of immediately available funds as directed in a written notice by
      the
      Company not less than two (2) Business Days in advance of the Closing and (ii)
      cancel the Note. In the event that payment by Occidental is made, in whole
      or in
      part, by cancellation of the Note, then Occidental will surrender the Note
      to
      the Company for cancellation at the Closing or
      shall
      execute an instrument of cancellation in form
      and
      substance reasonably acceptable to the Company. In the event that a Replacement
      Transaction is structured such that the Company is not the surviving corporation
      or survives as a subsidiary of another entity, then Occidental will have the
      right, prior to Closing, to elect to receive at Closing, in lieu of the shares
      of Series A Preferred Stock and upon payment of the amount set forth above,
      the
      consideration that would be receivable by a holder of that number of shares
      of
      Common Stock as would be issuable upon conversion of the shares of the Series
      A
      Preferred Stock that otherwise would have been issued to Occidental at Closing
      (the “Alternate
      Consideration”).
      

     

    1.3
      Pre-Closing Agreements.

     

    (a) Cash
      Shortfall Funding.
      Occidental agrees to advance up to $3,000,000 to the Company pursuant to the
      Note prior to the Closing (the “Cash
      Shortfall Amount”);
      provided
      that all
      of such Cash Shortfall Amount is used for (i) the Company’s reasonable and
      customary expenses associated with negotiating and consummating this Agreement,
      the transactions contemplated hereby and by the Transaction and, if applicable,
      the Replacement Transaction (including, without limitation, the reasonable
      fees
      and expenses of consultants hired to conduct diligence and reasonable legal
      fees), (ii) the deposit required to be paid by the Company under the terms
      of
      the Kern Acquisition Agreement or, if applicable, the terms of the Replacement
      Transaction and (iii) reasonable operating and other expenses of the Company
      for
      the period during which the Company seeks to consummate the Transaction or,
      if
      applicable, the Replacement Transaction. Occidental will advance portions of
      the
      Cash Shortfall Amount upon (A) the written request of the Company made from
      time
      to time and (B) submission of reasonably detailed invoices related to any amount
      requested. The Company agrees to repay all such amounts advanced in accordance
      with the terms of the Note. The Company will accept cancellation of the Note
      as
      payment for the shares of Series A Preferred Stock under Section
      1.2.

    (b) Option
      to Purchase.
      If the
      Transaction does not close, in consideration for making advances under the
      Note,
      Occidental will have the option, exercisable for ninety (90) days after the
      closing of a Replacement Transaction by the Company, to purchase up to three
      percent (3%) of the outstanding capital stock of the surviving entity in such
      transaction (in addition to the right to purchase Series A Preferred Stock
      or
      the Alternate Consideration) at a price per share equivalent to the
      lower
      of (i) the quotient of (A) the closing price per share of the Common Stock
      on
      the day preceding the closing date of such transaction and (B) the number of
      shares of capital stock of the surviving entity into which each share of Common
      Stock was converted in such transaction (which number shall be deemed to be
      one
      if the Common Stock was not converted in such transaction) (the “Conversion
      Ratio”)
      and
      (ii) the quotient of (A) the average of the closing price for each of the thirty
      (30) trading days immediately preceding the date on which the Company announces
      such transaction and (B) the Conversion Ratio, payable, in part, through
      cancellation of the Note. The
      “closing price” for each day shall be the last reported sales price or, in case
      no such reported sales take place on such day, the average of the closing bid
      and asked prices for such day, in each case as reported by the American Stock
      Exchange, or if such last sale price is not so reported by the American Stock
      Exchange, or if no such sale takes place on such day, the mean between the
      closing bid and asked prices for the Common Stock as reported by the American
      Stock Exchange. If the shares of Common Stock are not reported by the American
      Stock Exchange, the “closing
      price”
for
      each day shall be the last reported sales price or, in case no such reported
      sales take place on such day, the average of the closing bid and asked prices
      for such day, in each case as reported by the national exchange on which the
      Common Stock is traded. For the purpose hereof, trading day shall mean a day
      on
      which the specified securities exchange shall be open for business or, if the
      shares of Common Stock shall not be listed on such exchange for such period,
      a
      day with respect to which quotations of the character referred to in the next
      preceding sentence shall be reported.

     

    2.

    The
      Company hereby represents and warrants to Occidental that as of the

      Registration Rights.

     

    Except
      as
      provided in the Registration Rights Agreement and that certain Registration
      Rights Agreement dated as of January 30, 2007 between the Company, NTR Partners
      LLC and the other persons named therein (“Existing
      Registration Rights Agreement”),
      the
      Company is presently not under any obligation and has not granted any rights
      to
      register under the Securities Act any of its presently outstanding securities
      or
      any of its securities that may subsequently be issued.

     

    2.10
      Permits.

     

    The
      Company has all
      franchises,
      permits, licenses, and any similar authority necessary for the conduct of its
      business as now being conducted by it, the lack of which could materially and
      adversely affect the business, properties, prospects, or financial condition
      of
      the Company, and believes it can obtain, without undue burden or expense, any
      similar authority for the conduct of its business as presently planned to be
      conducted if failure to obtain them might result, either individually or in
      the
      aggregate, in any material adverse change in the assets, business, operations,
      properties, prospects, or condition (financial or otherwise) of the Company
      (as
      such business is presently conducted and as it is presently proposed to be
      conducted) (“Material
      Adverse Change”).
      The
      Company is not in default in any material respect under any of such franchises,
      permits, licenses or other sim-ilar authority.

     

    2.11
      Compliance With Other Instruments.

      of its Second Amended and Restated Certificate of Incorporation (the
“Certificate
      of Incorporation”)
      or
      Bylaws or in any material respect of any provision of any mortgage, indenture,
      agreement, (including the Existing Registration Rights Agreement) instrument,
      or
      contract to which it is a party or by which it is bound or, to the best of
      its
      knowledge, of any federal or state judgment, order, writ, decree, statute,
      rule,
      regulation or restriction applicable to the Company. The execution, delivery,
      and performance by the Company of this Agreement, the Shareholders Agreement,
      the Registration Rights Agreement, the borrowing under the Note and any
      Ancillary Agreement, and the consummation of the transactions contemplated
      hereby and thereby, will not (i) result in any such material violation or be
      in
      material conflict with or constitute, with or without the passage of time or
      giving of notice, either a material default under any such provision or an
      event
      that results in the creation of any material lien, charge, or encumbrance upon
      any assets of the Company or any of its Subsidiaries or the suspension,
      revocation, impairment, forfeiture, or nonrenewal of any material permit,
      license, authorization, or approval applicable to the Company or any of its
      Subsidiaries, its or their respective business or operations, or any of its

    2.12
      Litigation.

     

    There
      is
      no action, suit, proceeding, or investigation pending or, to the Company’s
      knowledge, currently threatened against the Company that questions the validity
      of this Agreement, the Shareholders Agreement, the Registration Rights
      Agreement, the Note or any Ancillary Agreement or the Kern Purchase Agreement
      or
      the right of the Company to enter into such agreements, or to consummate the
      transactions contemplated hereby or thereby, or that might result, either
      individually or in the aggregate, in a Material Adverse Change, or in any
      material change in the current equity ownership of the Company. The foregoing
      includes, without limitation, any action, suit, proceeding, or investigation
      pending or currently threatened involving the prior employment of any of the
      Company’s employees, their use in connection with the Company’s business of any
      information or techniques allegedly proprietary to any of their former
      employers, their obligations under any agreements with prior employers, or
      negotiations by the Company with potential backers of, or investors in, the
      Company or its proposed business. The Company is not a party to or, to the
      best
      of its knowledge, named in or subject to any order, writ, injunction, judgment,
      or decree of any court, government agency, or instrumentality. There is no
      action, suit, proceeding or investigation by the Company currently pending
      or
      that the Company currently intends to initiate.

     

    2.13
      Disclosure.

     

    The
      Company has provided Occidental with all the information reasonably available
      to
      it without undue expense that Occidental has requested for deciding whether
      to
      purchase the Series A Preferred Stock and all information that the Company
      believes is reasonably necessary to enable Occidental to make such decision.
      To
      the best of the Company’s knowledge after reasonable investigation, neither this
      Agreement nor any other agreements, written statements or certificates made
      or
      delivered in connection herewith contains any untrue statement of a material
      fact or omits to state a material fact necessary to make the statements herein
      or therein not misleading.

     

    2.14
      Offering.

     

    Subject
      in part to the truth and accuracy of Occidental’s representations set
      forth
      in this Agreement, the offer, sale and issuance of the Series A
      Preferred
      Stock as
      contemplated by this Agreement are exempt from the registration requirements
      of
      the Securities Act, and neither the Company nor any authorized agent
      acting on its behalf will take any action hereafter that would cause the
      loss
      of such
      exemption.

     

    2.15
      Title to Property and Assets; Leases.

     

    The
      Company has good and marketable title to its property and assets free and clear
      of all mortgages,
      liens, claims, and encumbrances, other than mortgages, liens, claims, and
      encumbrances that would not result, individually or in the aggregate, in a
      Material Adverse Change. With respect to the property and assets it
      leases,
      the Company is in material compliance with such leases and, to the best of
      its
      knowledge, holds a valid leasehold interest free of any liens, claims, or
      encumbrances,
      other
      than liens, claims, and encumbrances would not result, individually or in the
      aggregate, in a Material Adverse Change.

    2.16
      SEC Reports.

     

    The
      Company has complied in all material respects with requirements to file all
      reports, schedules, forms, statements and other documents required to be filed
      by the Company under the Securities Exchange Act of 1934, as amended, and all
      rules promulgated thereunder (the “Exchange
      Act”),
      including pursuant to Section 13(a) or 15(d) thereof, for the year preceding
      the
      date hereof (or such shorter period as the Company was required by law or
      regulation to file such material) (the foregoing materials, including the
      exhibits thereto and documents incorporated by reference therein, being
      collectively referred to herein as the “SEC
      Reports”)
      on a
      timely basis. As of their respective dates, the SEC Reports complied in all
      material respects with the requirements of the Securities Act and the Exchange
      Act, as applicable, and the rules and regulations of the Commission promulgated
      thereunder, and none of the SEC Reports, when filed, contained any untrue
      statement of a material fact or omitted to state a material fact required to
      be
      stated therein or necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading. The
      financial statements of the Company included in the SEC Reports (the
“Financial
      Statements”)
      comply
      in all material respects with applicable accounting requirements and the rules
      and regulations of the Securities and Exchange Commission (“Commission”),
      with
      respect thereto as in effect at the time of filing. Such financial statements
      have been prepared in accordance with United States generally accepted
      accounting principles applied on a consistent basis during the periods involved
      (“GAAP”),
      except as may be otherwise specified in such financial statements or the notes
      thereto and except that unaudited financial statements may not contain all
      footnotes required by GAAP, and fairly present in all material respects the
      financial position of the Company as of and for the dates thereof and the
      results of operations and cash flows for the periods then ended, subject, in
      the
      case of unaudited statements, to normal year-end audit adjustments.

     

    2.17
      Changes.

     

    As
      of the
      Closing date, since June 30, 2007,
      the only
      change in the assets, liabilities, financial condition, or operating results
      of
      the Company from that reflected in the SEC Reports as of June 30, 2007, have
      arisen only in the ordinary course of the Company’s business conducted in
      connection with its efforts to consummate the transactions contemplated by
      this
      Agreement, the Transaction and, if applicable, any Replacement Transaction
      and
      would not reasonably be expected to result in a Material Adverse Change except
      to the extent such Material Adverse Change was the result of changes affecting
      the business of all refiners generally and not within the control of the
      Company. Except as may be consented in writing by Occidental (such consent
      not
      to be unreasonably withheld or delayed), there has not been:

      material change to a material contract or arrangement by which the Company
      or
      any of its assets is bound or subject;

    (d) any
      material change in any compensation arrangement or agreement with any employee,
      officer, director or stockholder;

    

    (e) any
      resignation or termination of employment of any key officer of the Company;
      and
      the Company, to the best of its knowledge, does not know of the impending
      resignation or termination of employment of any such officer;

    

    (f) any
      mortgage, pledge, transfer of a security interest in, or lien, created by the
      Company, with respect to any of its material properties or assets, except liens
      for taxes not yet due or payable or contested by the Company in good faith
      and
      liens created pursuant to the senior secured revolving credit facility and
      term
      loan facility contemplated by the proposal letter, dated October 5, 2007,
      between Company and the proposed lender named therein;

    

    (g) any
      loans
      or guarantees made by the Company to or for the benefit of its employees,
      stockholders, officers, or directors, or any members of their immediate
      families, other than travel advances and other advances made in the ordinary
      course of its business;

    

    (h)
      except as may be required pursuant to the exercise of any conversion rights
      pursuant to Article SIXTH of the Company’s Certificate of Incorporation, any
      declaration, setting aside, or payment of any dividend or other distribution
      of
      the Company’s assets in respect of any of the Company’s capital stock, or any
      direct or indirect redemption, purchase, or other acquisition of any of such
      stock by the Company;

    

    (i) to
      the
      best of the Company’s knowledge, any other event or condition of any character
      that would reasonably be expected to result in a Material Adverse Change;
      or

    

    (j) any
      agreement or commitment by the Company to do any of the things described in
      this
Section
      2.17.

      except
      those
      contested by it in good faith. The provision for taxes of the Company as shown
      in the Financial Statements is, adequate for taxes due or accrued as of the
      date
      thereof. The Company has not elected pursuant to the Internal Revenue
      Code
      of 1986,
      as amended (“Code”), to be treated as an S corporation or a collapsible
      corporation pursuant to Section 1362(a) or Section 341(f) of the Code, nor
      has
      it made any other elections pursuant to the Code (other than elections that
      relate solely to methods of accounting, depreciation, or amortization) that
      would have a material effect on the business, properties, prospects, or
      financial condition of the Company. The Company has never had any tax deficiency
      proposed or assessed against it and has not executed any waiver of any statute
      of limitations on the assessment or collection of any tax or governmental
      charge. None of the Company’s federal income tax returns and none of its state
      income or franchise tax or sales or use tax returns has ever been audited by
      governmental authorities. Since the date of the Financial Statements, the
      Company has made adequate pro-visions on its books of account for all taxes,
      assessments, and governmental charges with respect to its business, properties,
      and operations for such period. The Company has withheld or collected from
      each
      payment made to each of its employees, the amount of all taxes, including,
      but
      not limited to, federal income taxes, Federal Insurance Contribution Act taxes
      and Federal Unemployment Tax Act taxes required to be withheld or collected
      therefrom, and has paid the same to the proper tax receiving officers or
      authorized depositaries.

    2.19
      Insurance.

     

    The
      Company has in full force and effect directors’ and officers’ indemnity
      insurance policies. With respect to Kern, the Company has, as of the Closing
      date, insurance in place in type and coverage in all material respects no less
      comprehensive than the insurance Kern had in place prior to the closing of
      the
      Kern Acquisition Agreement.

     

    2.20
      Minute Books.

     

    The
      copy
      of the minute books of the Company provided to Occidental’s counsel contains
      minutes of all meetings of directors and stockholders and all actions by written
      consent without a meeting by the directors and stockholders since the date
      of
      incorporation and accurately reflects all actions by the directors (and any
      committee of directors) and stockholders with respect to all transactions
      referred to in such minutes in all material respects.

     

    2.21
      Investment Company. 

     

    The
      Company is not, and is not an affiliate of, and immediately following the
      Closing will not have become and “investment company” within the meaning of the
      Investment Company Act of 1940, as amended.

     

    2.22 Listing
      and Maintenance Requirements. 

     

    The
      Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange
      Act, and the Company has taken no action designed to, or which to its knowledge
      is likely to have the effect of, terminating the registration of the Common
      Stock under the Exchange Act nor has the Company received any notification
      that
      the Commission is contemplating terminating such registration. The Company
      has
      not, in the twelve (12) months preceding the date of this Agreement, received
      notice from any trading market on which the Common Stock is or has been listed
      or quoted to the effect that the Company is not in compliance with the listing
      or maintenance requirements of such market. The Company is, and has no reason
      to
      believe that it will not in the foreseeable future continue to be, in compliance
      with all such listing and maintenance requirements.

    2.23 Representations
      and Warranties Regarding Kern.

     

    To
      the
      best of the Company’s knowledge after appropriate due diligence and
      investigation, each of the representations and warranties made with respect
      to
      Kern in Sections
      3.1(g) - (z) of
      the
      Kern Acquisition Agreement (i) if specifically qualified by materiality, is
      true
      and complete as so qualified and (ii) if not qualified by materiality, is
      true and correct in all material respects, in each case as of the date of the
      Kern Acquisition Agreement and the Closing date, except where any such
      representation or warranty is specific as of a specific earlier date, in which
      event it shall remain true and correct (as qualified) as of such earlier
      date.

      with or constitute, with or without the passage of time or giving of notice,
      either a material default under any such document.

      Occidental to enter into such agreements, or to consummate the transactions
      contemplated hereby or thereby.

     

    3.6
      Purchase Entirely for Own Account.

     

    This
      Agreement is made in reliance upon Occidental’s representation to the Company,
      which by Occidental execution of this Agreement Occidental’s hereby confirms,
      that the Series A Preferred Stock to be purchased by Occidental and the Common
      Stock issuable upon conversion thereof (collectively, the “Securities”)
      will
      be acquired for investment for Occidental’s own account, not as a nominee or
      agent, and not with a view to the
      resale or distribution of any part thereof, and that Occidental has no
      present
      intention of selling, granting any participation in, or otherwise distributing
      the same. By executing this Agreement, Occidental further represents that
      Occidental does not have any contract, undertaking, agreement or arrangement
      with any person to sell, transfer or grant participations to such person or
      to
      any third person, with respect to any of the Securities.

     

    3.7
      Restricted Securities.

     

    Occidental
      understands that the Series A Preferred Stock (and any Common
      Stock
      issued on conversion thereof) may not be sold, transferred, or otherwise
      disposed of without registration under the Securities Act or an exemption
therefrom,
      and that in the absence of an effective registration statement
      covering
      the
      Stock (or the Common Stock issued on conversion thereof) or an available
      exemption from registration under the Securities Act, the Series A Preferred
      Stock (and any Common Stock issued on conversion thereof) must be held
      indefinitely. 

     

    3.8
      Legends.

     

    To
      the
      extent applicable, each certificate or other document evidencing any
      of the
      Series A Preferred Stock or any Common Stock issued upon conversion thereof
      shall be endorsed with a legend substantially in the form set forth
      below:

    

    “THE
      SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
      OF
      1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR
      HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT, OR UNLESS THE COMPANY
      HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, SATISFACTORY TO THE
      COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.”

    3.9
      Financing.

     

    Occidental
      has, or will have at the Closing, sufficient cash available to pay amounts
      required to be paid pursuant to Section
      1.2(b),
      and to
      pay for any of the related fees and expenses Occidental incurs.
      

     

    3.10
      Blank Check Company.

     

    Occidental
      understands that the Company is a recently organized blank check company formed
      for the purpose of acquiring (an “initial business combination”) one or more
      businesses or assets in the energy industry (it being understood that the
      Transaction or a Related Transaction constitutes an initial business
      combination). Occidental further understands that (a) the Company’s assets
      consist of the cash proceeds of its public offering (the “IPO”) and private
      placements of its securities, and that substantially all of those proceeds
      have
      been deposited in a trust account with a third party (the “Trust Account”) for
      the benefit of the Company, certain of its stockholders and the underwriters
      of
      its IPO and (b) the monies in the Trust Account may be disbursed only (i) to
      the
      Company in limited amounts from time to time (and in no event more than
      $3,250,000 in total) in order to permit the Company to pay its operating
      expenses; (ii) if the Company completes an initial business combination, to
      certain dissenting public stockholders, to the underwriters for the IPO in
      the
      amount of underwriting discounts and commissions they earned in the IPO but
      whose payment they have deferred, and then to the Company; and (iii) if the
      Company fails to complete an initial business combination within the allotted
      time period and liquidates, subject to the terms of the agreement governing
      the
      Trust Account, to the Company in limited amounts to permit the Company to pay
      the costs and expenses of its liquidation and dissolution, and then to the
      Company’s stockholders who purchased securities in the IPO.

     

    4.
      CONDITIONS OF OCCIDENTAL’S OBLIGATIONS AT CLOSING.

    

    The
      obligations of Occidental under Section
      1.1(b)

      Closing, of each of the following

      had been made on and as of the Closing date (unless any such representation
      and

      the
      Closing to occur on or before such date; (ii)

      parties, if so mutually agreed in writing.

     

    6.2
      Effect of Termination.

     

    If
      this
      Agreement is terminated with respect to any party in accordance with this
Section
      6
      and the
      transactions contemplated hereby are not consummated, this Agreement, other
      than
      the provisions of this Section
      6.2
      and
Section
      7,
      shall
      become null and void and of no further force and effect, without any liability
      on the part of any party or its affiliates, directors, officers or
      stockholders; provided
      that
      nothing in this Section 6.2
      shall
      relieve any party to this Agreement of any liability resulting from a knowing
      and material breach of this Agreement on or prior to the date of
      termination.
      Notwithstanding anything to the contrary set forth in this Agreement, none
      of
      the parties hereto shall have any liability for speculative, indirect,
      unforeseeable or consequential damages or lost profits resulting from any legal
      action relating to this Agreement.
      For the
      avoidance of doubt, the Confidentiality Agreement between the Company and
      Occidental dated August 22, 2007 shall survive any termination of this
      Agreement.

      MISCELLANEOUS.

     

    7.1
      Entire Agreement.

     

    This
      Agreement and the documents referred to herein constitute the entire agreement
      among the parties and no party shall be liable or bound to any other party
      in
      any manner by any warranties, representations, or covenants, except as
      specifically set forth herein or therein.

    7.2
      Survival of Warranties.

     

    The
      warranties, representations, and covenants of the Company and Occidental
      contained in or made pursuant to this Agreement shall survive the execution
      and
      delivery of this Agreement and following the Closing.

     

    7.3
      Successors and Assigns.

     

    Except
      as
      otherwise provided herein, the terms and conditions of this Agreement shall
      inure to the benefit of and be binding upon the respective successors and
      assigns of the parties (including permitted transferees of any shares of Series
      A Preferred Stock sold hereunder or any Common Stock issued upon conversion
      thereof). Nothing in this Agreement, express or implied, is intended to confer
      upon any party other than the parties hereto or their respective successors
      and
      assigns any rights, remedies, obligations, or liabilities under or by reason
      of
      this Agreement, except as expressly provided in this Agreement.

     

    7.4
      Governing Law.

     

    This
      Agreement shall be governed by and construed under the laws of the State of
      New
      York as applied to agreements among New York residents entered into and to
      be
      performed entirely within New York. To the fullest extent permitted by
      applicable law, each party hereto (i) agrees that any claim, action or
      proceeding by such party seeking any relief whatsoever arising out of, or in
      connection with, this Agreement or the transactions contemplated hereby shall
      be
      brought only in the United States District Court for the Central District of
      California and in any California State court located in Los Angeles County
      and
      not in any other State or Federal court in the United States of America or
      any
      court in any other country, (ii) agrees to submit to the exclusive
      jurisdiction of such courts located in the State of California for purposes
      of
      all legal proceedings arising out of, or in connection with, this Agreement
      or
      the transactions contemplated hereby and (iii) irrevocably waives any
      objection which it may now or hereafter have to the laying of the venue of
      any
      such proceeding brought in such a court and any claim that any such proceeding
      brought in such a court has been brought in an inconvenient forum.

     

    7.5
      Specific Performance

     

    The
      parties hereto acknowledge that monetary damages are not an adequate remedy
      for
      violations of Section
      1,
      and
      that any party hereto may, in its sole discretion, apply to a court of competent
      jurisdiction for specific performance or injunctive or such other relief as
      such
      court may deem just and proper in order to enforce such Section and prevent
      any
      violation thereof and, to the extent permitted by applicable law and to the
      extent the party seeking such relief would be entitled on the merits to obtain
      such relief, each party hereto waives any objection to the imposition of such
      relief.

     

    7.6
      No Third-Party Beneficiaries. 

     

    This
      Agreement is for the sole benefit of the parties hereto and their respective
      successors and permitted assigns and nothing herein, express or implied, is
      intended or shall confer upon any other person any legal or equitable right,
      benefit or remedy of any nature whatsoever under or by reason of this
      Agreement.

    This
      Agreement may be executed in two or more counterparts, each of which shall
      be
      deemed an original, but all of which together shall constitute one and the
      same
      instrument.

     

    7.8
      Titles and Subtitles.

     

    The
      titles and subtitles used in this Agreement are used for convenience only and

      All such notices and other written communications shall be effective on the
      date
      of mailing, confirmed facsimile transfer or delivery.

     

    7.10
      Finder’s Fees.

     

    Each
      party represents that it neither is nor will be obligated for any
      finder’s
      fee or
      commission in connection with this transaction. Occidental
      agrees
      to indemnify and to hold harmless the Company from
      any
      liability for any commission or compensation in the nature of a finder’s fee
      (and the reasonable costs and expenses of defending against such liability
      or
      asserted liability) for which Occidental or any of its officers, partners,
      employees, or representatives is responsible. The
      Company agrees to indemnify and hold harmless Occidental from any liability
      for any commission or compensation in the nature of a finder’s
      fee
      (and the reasonable costs
      and
      expenses of defending against such liability or asserted liability) for
      which
      the
      Company or any of its officers, employees, or representatives is
      responsible.

     

    7.11
      Expenses.

     

    Irrespective
      of whether the Closing is effected, each party will pay all costs and expenses
      that it incurs with respect to the negotiation, execution, delivery, and
      performance of this Agreement. 

     

    7.12
      Attorneys’ Fees.

     

    If
      any
      action at law or in equity is necessary to enforce or interpret the terms of
      this Agreement, the Shareholders Agreement, the Registration Rights Agreement,
      the Note, any Ancillary Agreement or the Certificate of Designations, the
      prevailing party shall be entitled to reasonable attorneys’ fees, costs, and
      disbursements in addition to any other relief to which such party may be
      entitled.

    7.13
      Amendments and Waivers.

     

    Any
      term
      of this Agreement may be amended and the observance of any term
      of
      this Agreement may be waived (either generally or in a particular
      instance
      and
      either retroactively or prospectively), only with the written consent of the
      Company and Occidental. Any amendment or waiver effected in accordance with
      this
      Section will be binding upon Occidental, each future holder of all Securities
      purchased under this Agreement (including Securities into which the purchased
      securities are converted), and the Company.

     

    7.14
      Severability.

     

    If
      one or
      more provisions of this Agreement are held to be unenforceable under applicable
      law, such provision shall be excluded from this Agreement and the balance of
      the
      Agreement shall be interpreted as if such provision were so excluded and shall
      be enforceable in accordance with its terms.

     

    7.15
      Public Announcements.

     

    Subject
      to each party’s disclosure obligations imposed by law, rule or regulation, each
      of the parties hereto will cooperate with each other in the development and
      distribution of all news releases and other public information disclosures
      with
      respect to this Agreement and any of the transactions contemplated hereby,
      and
      no party hereto will make any such news release or public disclosure without
      first consulting with the other party hereto.

     

    7.16
      Trust Account Waiver.

     

    Unless
      and until the Closing occurs, Occidental waives any right, title, interest
      or
      claim of any kind (any “Claim”)
      it or
      any of its affiliates have or may have in the future in or to any monies in
      the
      Trust Account and agrees not to seek recourse against the Trust Account or
      any
      funds distributed therefrom (except amounts properly released to the Company
      as
      described in Section
      3.9)
      as a
      result of, or arising out of, any Claims against the Company in connection
      with
      this Agreement or any other agreement with the Company.

     

    7.17
      Schedule of Exceptions.

     

    From
      time
      to time prior to the Closing, the Company may supplement or amend the Schedule
      of Exceptions with respect to any matter (i) which may arise hereafter and
      which, if existing or occurring at or prior to the date hereof, would have
      been
      required to be set forth or described in the Schedule of Exceptions or (ii)
      which makes it necessary to correct or update any information in the Schedule
      of
      Exceptions or in any representation and warranty of the Company which has been
      rendered inaccurate thereby. To the extent the Company makes any such
      supplements or amendments to the Disclosure Schedule after the date hereof
      and
      prior to the Closing, the Disclosure Schedule and the related representations
      and warranties shall be deemed modified as of the Closing to the extent set
      forth in such supplements or amendments; provided,
      however,
      that if
      any matter disclosed pursuant to Section
      7.17(ii)
      would,
      individually or in the aggregate, reasonably be expected to result in a Material
      Adverse Change, Occidental may terminate this Agreement by written notice to
      the
      Company.

      IS
      ON FILE WITH THE COMPANY. NO TRANSFER SHALL BE EFFECTIVE UNLESS AND UNTIL THE
      TERMS AND CONDITIONS OF SUCH SHAREHOLDERS RIGHTS AGREEMENT HAVE BEEN COMPLIED

      OF
      1933, AS AMENDED, AND MAY NOT BE SOLD OR TRANSFERRED, ASSIGNED, PLEDGED OR
      HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT OR UNLESS THE COMPANY
      HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, SATISFACTORY TO THE
      COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

    

    (c) The
      Company shall be obligated to promptly reissue unlegended certificates at the
      request of any Holder thereof if the Holder shall have obtained an opinion
      of
      counsel at such Holder’s expense (which counsel may be counsel to the Company)
      reasonably acceptable to the Company to the effect that the securities proposed
      to be disposed of may lawfully be so disposed of without registration,
      qualification or legend.

     

    (d) Any
      legend endorsed on an instrument pursuant to applicable state securities
      laws and the stop-transfer instructions with respect to such securities
      shall
      be
      removed upon receipt by the Company of an order of the appropriate blue sky
      authority authorizing such removal.

      Company may satisfy the provisions of Sections
      2.1(a)

      the Exchange Act. 

     

    2.2
      Additional Information and Rights.

    

    (a) The
      Company will permit any Holder that owns at least seventy-five percent (75%)
      of
      the Shares (as presently constituted and subject to subsequent adjustment for
      stock splits, stock dividends, reverse stock splits, recapitalizations and
      the
      like) (a “Significant
      Holder”),
      or a
      representative of any Significant Holder, to visit and inspect any of the
      properties of the Company, including its books of account and other records
      (and
      make copies thereof and take extracts therefrom), and to discuss its affairs,
      finances and accounts with the Company’s officers and its independent public
      accountants, upon reasonable advance notice, all at such reasonable times and
      as
      often as any such person may reasonably request.

    

    (b) The
      Company will deliver the reports described below in this Section
      2.2
      to each
      Significant Holder, who so requests in writing, with reasonable promptness,
      such
      other information and data with respect to the Company and its subsidiaries
      as
      any such Significant Holder may from time to time reasonably
      request.

    

    (c) The
      provisions of Section
      2.1
      and this
Section
      2.2
      shall
      not be in limitation of any rights which any Holder or Significant Holder may
      have with respect to the books and records of the Company, or to inspect its
      properties or discuss its affairs, finances and accounts, under the laws of
      the
      State of Delaware.

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

    

    (d) Anything
      in Section
      2.2
      to the
      contrary notwithstanding, no Holder by reason of this agreement shall have
      access to any trade secrets or confidential information of the Company. Each
      Holder hereby agrees to hold in confidence and trust
      and
      not to misuse or disclose any confidential information provided
      pursuant
      to this
Section
      2.2, provided,
      however,
      (i)
      that
      in the event a Holder or any of its representatives are requested in a legal
      proceeding (by deposition, interrogatories, requests for information or
      documents in legal proceedings, subpoena, civil investigative demand or other
      similar process) to disclose any of information, the Holder shall give the
      Company prompt notice of such request so that the Company may seek a protective
      order or other similar relief with respect to such disclosure so as to maintain
      the confidential nature of the information to be disclosed after which the
      Holder may make required disclosures, (ii) that in the event that a Holder
      or
      its representatives are otherwise required by law or stock
      exchange regulations or by a governmental order, decree, regulation
      or rule
      or legal process
      to
      disclose any of the information, the Holder shall give the Company notice of
      the
      information to be disclosed and such opportunity as is reasonably practicable
      to
      review the proposed disclosure and to comment thereon after which the Holder
      may
      make required disclosures, and (iii) the Company recognizes that the Holder
      and
      its representatives may
      retain mental impressions of the information and that such Persons may, now
      or
      in the future, be working on other projects, whether or not related to the
      Company and, consequently, notwithstanding anything in this Agreement, the
      parties agree that such Persons will not be precluded from working on such
      other
      projects solely because of the retained mental impressions of the
      information.

    

    2.3
      Right of First Refusal. 

    

     (a)
      The
      Company hereby grants to each Holder who owns
      any
      shares
      of Series
      A Preferred Stock
      the
      right of first refusal to purchase a pro rata share of New Securities that
      the
      Company may, from time to time, propose
      to sell
      and issue. A Holder’s pro rata share, for purposes of this right of first
      refusal,
      is
      the ratio of the sum of (i) the number of Shares owned by such Holder
      immediately prior to the issuance of New Securities, assuming full
      conversion of
      the
      Series A Preferred Stock held by the Holder and (ii) any New Securities
      previously purchased by the Holder under this Section
      2.3(a)
      and
      owned by such Holder immediately prior to the issuance of New Securities
      (collectively, “Base
      Securities”),
      assuming full conversion, exercise or exchange, if any is possible, of such
      New
      Securities, to the total
      number of shares of Common Stock outstanding immediately prior to the
      issuance
      of
      New Securities, assuming full conversion, exercise or exchange of the Base
      Securities and exercise of
      all
      other outstanding convertible securities, rights, options and warrants to
      acquire Common
      Stock of the Company. Each Holder shall have a right of
      over-allotment such
      that
      if any Holder fails to exercise its right hereunder to purchase its pro
      rata
      share of
      New Securities, the other Holders may purchase the non-purchasing Holder’s
      portion on a pro rata basis within five (5) days from the date such
      non-purchasing Holder fails to exercise its right hereunder to purchase its
      pro
      rata share of New Securities. 

    
      
        
        

      

      
        6

        
          

        

      

      
        
        

      

    

    

    (b) In
      the
      event the Company proposes to undertake an issuance of New Securities, it shall
      give each Holder written notice of its intention, describing the type of New
      Securities, and their price and the general terms upon which the Company
      proposes to issue the same. Each Holder shall have ten (10) Business Days after
      any such notice is mailed or delivered to agree to purchase such Holder’s pro
      rata share of such New Securities for the price and upon the terms specified
      in
      the notice by giving written notice to the Company and stating therein the
      quantity of New Securities to be purchased.

    

    (c) In
      the
      event the Holders fail to exercise fully the right of first refusal within
      said
      ten (10) Business Day period and after the expiration of the five (5)Business
      Day period for the exercise of the over-allotment provisions of this
Section
      2.3,
      the
      Company shall have one hundred fifty (150) days thereafter to sell to sell
      the
      New Securities respecting which the Holders’ right of first refusal option set
      forth in this Section
      2.3
      was not
      exercised, at a price and upon terms no more favorable to the purchasers thereof
      than specified in the Company’s notice to Holders pursuant to Section
      2.3(b).
      In the
      event the Company has not sold the New Securities in accordance with the
      foregoing within one hundred fifty (150) days from the expiration of the ten
      (10)Business Day period for the exercise of the over-allotment provisions,
      the
      Company shall not thereafter issue or sell any New Securities, without first
      again offering such securities to the Holders in the manner provided in
Section
      2.3(b).
      

    

    (d) The
      right
      of first refusal set forth in this Section
      2.3
      may not
      be assigned or transferred, except that (i) such right is assignable by each
      Holder to any wholly owned subsidiary or parent of, or to any Person that is,
      within the meaning of the Securities Act, controlling, controlled by or under
      common control with, any such Holder, and (ii) such right is assignable between
      and among any of the Holders.

    

    2.4
      Exchange Right.

    

    The
      Company hereby grants to Occidental the right, during the period ending on
      the
      date that is two (2) years after the Closing, to exchange Series A Preferred
      Stock for Exchange Debt that the Company may, from time to time, propose to
      sell
      and issue as set forth in this Section
      2.4.
      In the
      event the Company proposes to incur Exchange Debt, it shall give Occidental
      written notice of its intention, describing the type of Exchange Debt, and
      its
      interest rate and the general terms upon which the Company proposes to incur
      the
      same. Occidental may exercise the exchange right set forth in this Section
      2.4
      (the
“Exchange
      Right”)
      by
      providing written notice to the Company of its election and the aggregate
      liquidation preference of the Series A Preferred Stock it elects to exchange
      not
      less than 10 Business Days prior to the incurrence of such Exchange Debt. If
      Occidental exercises the Exchange Right, the Company will issue Exchange Debt
      to
      Occidental in an aggregate principal amount equal to the aggregate liquidation
      preference of the Series A Preferred Stock indicated in the election notice
      upon
      surrender by Occidental of certificates representing Series A Preferred Stock
      at
      least equal to those noted in the exchange notice. If Occidental surrenders
      certificates representing excess shares of Series A Preferred Stock, the Company
      will provide a replacement certificate to Occidental representing such excess
      shares.

    2.5
      Tag Along Rights.

    

    (a)
      If
      Partners, Additional Holders or any of their respective successors and assigns
      desire (“Prospective
      Sellers”)
      to
      effect any sale or transfer (other than a sale or transfer to the public
      pursuant to a registration statement or Rule 144 under the Securities Act)
      of
      any Warrants or Common Stock to any Independent Third Party which (when
      aggregated with all prior such sales or transfers) represents more than
      1,000,000 shares of Common Stock (assuming exercise of all the Warrants) (a
      “Tag
      Along
      Transaction”),
      then,
      for so long as Occidental beneficially owns any shares of Series A Preferred
      Stock, Prospective Sellers shall give written notice to Occidental offering
      Occidental the option to participate in the Tag
      Along
      Transaction (a “Sale
      Notice”),
      not
      less than seven (7) Business Days prior to the date of closing of such Tag
      Along
      Transaction. The Sale Notice shall set forth the material terms of the proposed
      Tag
      Along
      Transaction and identify the contemplated transferee(s).

    

    (b)
      Occidental may, by written notice to Prospective Sellers (a “Tag
      Along Notice”)
      delivered within three (3) Business Days after the date of the Sale Notice,
      elect to sell in such Tag
      Along
      Transaction any shares of Series A Preferred Stock held by it.

    

    (c)
      If
      Occidental fails to deliver a timely Tag
      Along
      Notice,
      then Prospective Sellers, may thereafter consummate the Tag
      Along
      Transaction at the same price and on substantially the same terms and conditions
      as are described in the Sale Notice (including, without limitation, the number
      of shares of Common Stock being directly or indirectly sold). If Occidental
      gives Prospective Sellers a timely Tag
      Along
      Notice,
      then Prospective Sellers shall use all reasonable efforts to cause the
      prospective transferee(s) to agree to acquire all Series A Preferred Stock
      identified in the Tag
      Along
      Notice,
      upon the same terms and conditions as are applicable to the Warrants or Common
      Stock held by Prospective Sellers (using an as-converted comparison of the
      Warrants and the Series A Preferred Stock and accounting for the fact that
      the
      Series A Preferred Stock has been paid). If such prospective transferee is
      unable or unwilling to acquire all Series A Preferred Stock proposed to be
      included in the Tag
      Along
      Transaction upon such terms, then Prospective Sellers may elect either to cancel
      such Tag
      Along
      Transaction or to sell the maximum number of shares of Series A Preferred Stock
      that such prospective transferee(s) is willing to purchase. Occidental shall
      deliver any shares of Series A Preferred Stock sold in any transaction pursuant
      to this Section
      2.5
      free and
      clear of liens, encumbrances and adverse claims with respect thereto. If
      Occidental participates in any such Tag Along Transaction, it shall be
      responsible for its proportionate share of the costs of the Tag Along
      Transaction to the extent not paid or reimbursed by the contemplated transferee
      or the Company.

    

    (d)
      For
      the avoidance of doubt, the terms set out in this Section
      2.5
      shall
      not apply to any sale or transfer of any Warrants or Common Stock to any
      affiliate of Prospective Sellers; provided
      that
      such affiliate agrees to be bound to the terms hereof with respect to such
      Warrants or Common Stock.

    2.6
      Prompt Payment of Taxes, etc. The
      Company will promptly pay and discharge, or cause to be paid and discharged,
      when due and payable, all lawful taxes, assessments and governmental charges
      or
      levies imposed upon the income, profits, property or business of the Company
      or
      any subsidiary; provided,
      however,
      that
      any such tax, assessment, charge or levy need not be paid if the validity
      thereof shall currently be contested in good faith by appropriate proceedings
      and if the Company shall have set aside on its books adequate reserves with
      respect thereto; and provided,
      further,
      that
      the Company will pay all such taxes, assessments, charges or levies forthwith
      upon the commencement of proceedings to foreclose any lien which may have
      attached as security therefor. The Company will promptly pay or cause to be
      paid
      when due, or in conformance with customary trade terms or otherwise in
      accordance with policies related thereto adopted by the Company’s Board of
      Directors, all other indebtedness incident to operations of the
      Company.

     

    2.7
      Maintenance of Properties and Leases.  The Company
      will keep its properties and
      those
      of its subsidiaries
      in good
      repair, working order and
      condition, reasonable
      wear and tear excepted, and from time to time make all necessary and proper
      repairs, renewals, replacements, additions and improvements thereto except
      to
      the extent failure would not result, either individually or in the aggregate,
      in
      any material adverse change in the assets, business, operations, properties,
      prospects, or condition (financial or otherwise) of the Company (as such
      business is presently conducted and as it is presently proposed to be conducted)
      (“Material
      Adverse Change”);
      and
      the Company and its subsidiaries will at all times comply with each material
      provision
      of
      all leases to which
      any
      of them is a
      party
      or under which
      any
      of them occupies
      property if the breach
      of such
      provision would reasonably be expected to have a Material Adverse
      Change.

     

    2.8
      Insurance.
      Except
      as
      otherwise decided in accordance with policies adopted by the Company’s Board of
      Directors, the Company will keep its assets and those of its subsidiaries which
      are of an insurable character insured by financially sound and reputable
      insurers against loss or damage by fire, explosion and other risks customarily
      insured against by companies in the Company’s line of business, and the Company
      will maintain, with financially sound and reputable insurers, insurance against
      other hazards and risks and liability to persons and property to the extent
      and
      in the manner customary for companies in similar businesses similarly
      situated.

     

    2.9
      Accounts and Records.
      The
      Company will keep true records and books of account in which full, true and
      correct entries will be made of all dealings or transactions
      in relation to its business and affairs in accordance
      with generally
      accepted
      accounting principles applied on a consistent basis.

     

    2.10
      Compliance with Requirements of Government Authorities.
      The
      Company and all its subsidiaries shall duly observe and conform to all valid
      requirements of governmental authorities relating to the conduct of their
      businesses or to their
      properties and assets
      if the
      failure to observe them would reasonably be expected to result in a Material
      Adverse Change.

    2.11
      Maintenance of Corporate Existence, etc.
      The
      Company shall, and shall cause its material subsidiaries to, maintain in full
      force and effect its corporate existence, rights and franchises and all licenses
      and other rights in or to use patents, processes, licenses, trademarks, trade
      names or copyrights owned or possessed by it or any subsidiary and necessary
      to
      the conduct of their business,
      the
      failure of to
      maintain which
      would
      reasonably be expected to result in a Material Adverse Change.

     

    2.12
      Transactions with Affiliates. The
      Company shall not, without the approval of the disinterested members of the
      Company’s Board of Directors, engage
      in
      any loans, leases, contracts or other transactions with any director,
      officer
      or key
      employee of the Company, or any member of any such person’s immediate
      family, including the parents, spouse, children and other relatives of any
      such
      person,
      on terms less favorable than the Company would obtain in a transaction with
      an
      unrelated party, as determined in good faith by the Board of
      Directors.

     

    2.13
      Attendance at Board Meetings.

    So
      long
      as Occidental continues to beneficially own, in the aggregate, not less than

      A
      Agreement, Occidental shall have the right to attend all meetings of the Board
      of Directors in a monitoring observer capacity, to receive notice of such
      meetings and to receive the information provided by the Company to the Board
      of
      Directors.

     

    2.14
      Restrictions on Corporate Actions.

    So
      long
      as Occidental beneficially owns any shares of the Series A Preferred Stock,

      affiliates, successors and assigns will not vote or otherwise grant approval
      to,
      amend the Company’s Certificate of Incorporation without the written approval of
      Occidental if such amendment would change any of the rights, preferences or
      privileges provided for the benefit of holders of any shares of the Series
      A
      Preferred Stock. Without limiting the generality of the preceding sentence,
      so
      long as Occidental beneficially owns any shares of the Series A Preferred Stock,
      the Company will not, and Partners, Additional Holders and their respective
      affiliates, successors and assigns will not, vote or otherwise grant approval
      to, amend the Company’s Certificate of Incorporation without the written
      approval of Occidental if such amendment would:

    

    (i) Reduce
      the dividend rates on the Series A Preferred Stock, make such dividends

      accrued and unpaid dividends, or change the relative seniority rights of the

      relation to the holders of any other capital stock of the Company;

     

    (ii) Reduce
      the amount payable to the holders of Series A Preferred Stock upon the voluntary
      or involuntary liquidation, dissolution, or winding up of the Company, or change
      the relative seniority of the liquidation preferences of the holders of the
      Series A Preferred Stock to the rights upon liquidation of the holders of any
      other capital stock of this Corporation;

    

    (iii) Reduce
      the Series A Preferred Stock redemption price;

    
      
        
        

      

      
        10

        
          

        

      

      
        
        

      

    

    (iv) Delay
      the
      Series A Preferred Stock redemption date;

     

    (v) Make
      the
      Series A Preferred Stock redeemable at the option of the Company;
      or

     

    (vi) Cancel
      or
      modify the conversion rights of the Series A Preferred Stock.

     

    (vii) Change
      the rights of the holders of the Series A Preferred Stock to appoint directors
      of the Company.

    

    So

      eighty percent (80%) of the Series A Preferred Stock issued under the Series
      A
      Agreement, the Company will not, and Partners, Additional Holders and their
      respective affiliates, successors and assigns will not vote or otherwise grant
      approval to, amend the Company’s Certificate of Incorporation or By-laws without
      the approval, by vote or written consent, by all of the holders of the Series
      A
      Preferred Stock to provide for any new class or series of capital stock having
      any rights, preferences or privileges senior to or on a parity with the rights,
      preferences or privileges provided for the benefit of holders of any shares
      of
      the Series A Preferred Stock.

          Entire
          Agreement; Amendment; Waiver. This

      or omission to exercise any right, power or remedy accruing to any Holder,
      upon
      any breach or default of the Company under this Agreement
      shall
      impair any such right, power or remedy of such Holder nor shall it be construed
      to be a waiver of any such breach or default, or an acquiescence therein, or

      or in any similar breach or default thereafter occurring; nor shall any waiver
      of any single breach or default be deemed a waiver of any other breach or
      default therefore or thereafter occurring. Any waiver, permit,
