    REGISTRATION
      RIGHTS

     

    Section
      2.01  Registration.

     

    (a)  Registration.

     

    (i)  Deadline
      To File and Go Effective. 
      As soon as practicable following January 1, 2008, but in any event prior to
      January 31, 2008 (the “File
      Date”),
      Atlas
      Energy shall prepare and file a registration statement under the Securities
      Act
      to permit the resale of the Registrable Securities from time to time, including
      as permitted by Rule 415 under the Securities Act (or any similar provision
      then
      in force), with respect to all of the Registrable Securities (the “Registration
      Statement”). 
      Atlas Energy shall use its commercially reasonable efforts to cause the
      Registration Statement to become effective no later than May 30, 2008 (the
      “Target
      Effective Date”). 
      A Registration Statement filed pursuant to this Section
      2.01
      shall be
      on Form S-3 under the Securities Act.  Atlas Energy will use its
      commercially reasonable efforts to cause the Registration Statement filed
      pursuant to this Section
      2.01
      to be
      continuously effective under the Securities Act until the earlier of (i) the
      date as of which all such Registrable Securities are sold by the Purchasers
      and
      (ii) two years following the Closing Date (the “Effectiveness
      Period”). 
      The Registration Statement when effective (including the documents incorporated
      therein by reference) shall comply as to form with all applicable requirements
      of the Securities Act and the Exchange Act and shall not contain an untrue
      statement of a material fact or omit to state a material fact required to be
      stated therein or necessary to make the statements therein not
      misleading.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    (ii)  Failure
      To Go Effective. 
      If the Registration Statement required by Section
      2.01
      is not
      effective by the Target Effective Date, then each Purchaser shall be entitled
      to
      a payment with respect to such Purchaser’s Registrable Securities, as liquidated
      damages and not as a penalty, of 0.25% of the Liquidated Damages Multiplier
      per
      30-day period for the first 30 days following the Target Effective Date,
      increasing by an additional 0.25% of the Liquidated Damages Multiplier per
      30-day period for each subsequent 30 days, up to a maximum of 1.00% of the
      Liquidated Damages Multiplier per 30-day period (the “Liquidated
      Damages”). 
      The Liquidated Damages payable pursuant to the immediately preceding sentence
      shall be payable within ten Business Days of the end of each such 30-day
      period.  Liquidated Damages for any period of less than 30-days shall be
      prorated by multiplying Liquidated Damages to be paid in a full 30-day period
      by
      a fraction, the numerator of which is the number of days for which Liquidated
      Damages are owed, and the denominator of which is 30. Any Liquidated Damages
      shall be paid to each Purchaser in cash or immediately available funds;
provided,
      however,
      if
      Atlas Energy certifies that it is unable to pay Liquidated Damages in cash
      or
      immediately available funds because such payment would result in a breach
      under any of Atlas Energy’s or Atlas Energy’s Subsidiaries’ credit facilities or
      other indebtedness filed as exhibits to the Atlas Energy SEC Documents, then
      Atlas Energy may pay the Liquidated Damages in kind in the form of the issuance
      of additional (A) Common Units or (B) Common Units or Class D
      Units.  Class D Units may only be issued as Liquidated Damages if and to
      the extent Atlas Energy is restricted from issuing Common Units pursuant to
      the
      rules of The New York Stock Exchange or similar regulation.  If Class D
      Units are issued as Liquidated Damages as a result of a requirement by The
      New
      York Stock Exchange or similar regulation, then such Common Units and/or Class
      D
      Units will be issued to each Purchaser on a pro rata basis in such a manner
      as
      to maximize the number of Common Units issued to each such Purchaser.  Upon
      any issuance of Common Units and/or Class D Units as Liquidated Damages, Atlas
      Energy shall promptly prepare and file an amendment to the Registration
      Statement prior to its effectiveness adding such Common Units and/or Common
      Units issuable upon conversion of Class D Units to such Registration Statement
      as additional Registrable Securities.  The determination of the number of
      Common Units and Class D Units to be issued as Liquidated Damages shall be
      equal
      to the amount of Liquidated Damages divided by the volume weighted average
      closing price of the Common Units (as reported by The New York Stock Exchange)
      for the ten trading days immediately preceding the date on which the Liquidated
      Damages payment is due, less a discount of 2%.  Any obligation of Atlas
      Energy to pay Liquidated Damages (other than Liquidated Damages owing but not
      yet paid) to a Purchaser shall cease two years following the Closing Date. 
As soon as practicable following the date that the Registration Statement or
      any
      post-effective amendment thereto becomes effective, but in any event within
      two
      Business Days of such date, Atlas Energy shall provide the Purchasers with
      written notice of the effectiveness of the Registration Statement.

     

    (iii)  Waiver
      of Liquidated Damages. 
      If Atlas Energy is unable to cause a Registration Statement to become effective
      by the Target Effective Date as a result of an acquisition, merger,
      reorganization, disposition or other similar transaction, then Atlas Energy
      may
      request a waiver of the Liquidated Damages, which may be granted or withheld
      by
      the consent of the Holders of two-thirds of the aggregate of the Purchased
      Class
      D Units and the Purchased Units, voting as a single class, in their sole
      discretion.  

     

    (b)  Delay
      Rights. 
      Notwithstanding anything to the contrary contained herein, Atlas Energy may,
      upon written notice to all of the Selling Holders whose Registrable Securities
      are included in the Registration Statement, suspend such Selling Holders’ use of
      any prospectus which is a part of the Registration Statement (in which event
      each such Selling Holder shall discontinue sales of the Registrable Securities
      pursuant to the Registration Statement) but such Selling Holder may settle
      any
      sales of Registrable Securities, if (i) Atlas Energy is pursuing an acquisition,
      merger, reorganization, disposition or other similar transaction and Atlas
      Energy determines in good faith that Atlas Energy’s ability to pursue or
      consummate such a transaction would be materially adversely affected by any
      required disclosure of such transaction in the Registration Statement or (ii)
      Atlas Energy has experienced some other material non-public event, the
      disclosure of which at such time, in the good faith judgment of Atlas Energy,
      would materially adversely affect Atlas Energy; provided,
      however,
      in no
      event shall such Selling Holders be suspended from selling Registrable
      Securities pursuant to the Registration Statement for a period that exceeds
      an
      aggregate of 30 days in any 90-day period or 90 days in any 365-day
      period.  Upon disclosure of such information or the termination of the
      condition described above, Atlas Energy shall (i) provide prompt notice to
      the
      Selling Holders whose Registrable Securities are included in the Registration
      Statement, (ii) promptly terminate any suspension of sales it has put into
      effect and (iii) take such other actions to permit sales of Registrable
      Securities as contemplated in this Agreement.

    (c)  Additional
      Rights to Liquidated Damages. 
      If (i) the Holders shall be prohibited from selling their Registrable Securities
      under the Registration Statement as a result of a suspension pursuant to
Section
      2.01(b)
      of this
      Agreement in excess of the periods permitted therein or (ii) the Registration
      Statement is filed and effective but, during the Effectiveness Period, shall
      thereafter cease to be effective or fail to be usable for its intended purpose
      without being succeeded by a post-effective amendment to the Registration
      Statement, a supplement to the prospectus or a report filed with the Commission
      pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until
      the suspension is lifted or a post-effective amendment, supplement or report
      is
      filed with the Commission and effective, but not including any day on which
      a
      suspension is lifted or such amendment, supplement or report is filed and
      effective, if applicable, Atlas Energy shall owe the Holders an amount equal
      to
      the Liquidated Damages, following (x) the date on which the suspension period
      exceeded the permitted period under Section
      2.01(b)
      of this
      Agreement or (y) the date after the Registration Statement ceased to be
      effective or failed to be useable for its intended purposes, as liquidated
      damages and not as a penalty.  For purposes of this Section
      2.01(c),
      a
      suspension shall be deemed lifted on the date that notice that the suspension
      has been lifted or that a post-effective amendment is effective is delivered
      to
      the Holders pursuant to Section
      3.01
      of this
      Agreement.

     

    (d)  S-1
      Filing.
      In
      addition to the rights provided in Section 2.01(a), if Atlas Energy is not
      eligible to file a shelf registration statement on Form S-3 on the File Date,
      one or more Holders collectively holding greater than $25 million of Registrable
      Securities, based on the Average Purchase Price, may thereafter deliver written
      notice to Atlas Energy that such Holders wish to register under the Securities
      Act an aggregate of at least $25 million of Registrable Securities, based on
      the
      Average Purchase Price specifying the amount and intended method of disposition
      of such Registrable Securities. Atlas Energy will promptly give written notice
      of such requested registration to all other Holders, and thereupon will, as
      expeditiously as possible, use its reasonable best efforts to effect the
      registration under the Securities Act of (i) such Registrable Securities which
      the Company has been so requested to register by the such Holders; and (ii)
      all
      other Registrable Securities which Atlas Energy has been requested to register
      by any other Holder (which request shall specify the amount and intended method
      of disposition of such Registrable Securities, including an Underwritten
      Offering) to the extent necessary to permit the disposition (in accordance
      with
      the intended method thereof as aforesaid) of the Registrable Securities so
      to be
      registered.

      Section
        2.02  Piggyback
        Rights.

       

      (a)  Participation. 
        If
        at any
        time Atlas Energy proposes to file (i) a shelf registration statement other
        than
        the Registration Statement (in which event Atlas Energy covenants and agrees
        to
        include thereon a description of the transaction under which the Purchasers
        acquired the Registrable Securities) and a prospectus supplement related
        to such
        shelf registration, (ii) a prospectus supplement to an effective shelf
        registration statement, other than the Registration Statement contemplated
        by
Section
        2.01
        of this
        Agreement
        and
        Holders may be included without the filing of a post-effective amendment
        thereto, or
        (iii)
        a
        registration statement, other than a shelf registration statement, in any
        case,
        for the sale of Common Units in an Underwritten Offering for its own account
        and/or another Person, then as soon as practicable but not less than three
        Business Days prior to the filing of (x) any preliminary prospectus supplement
        relating to such Underwritten Offering pursuant to Rule 424(b) under the
        Securities Act, (y) the prospectus supplement relating to such Underwritten
        Offering pursuant to Rule 424(b) under the Securities Act (if no preliminary
        prospectus supplement is used) or (z) such registration statement (only in
        respect of clause (iii) above for purposes of this clause (z)), as the case
        may
        be, then Atlas Energy shall give notice (including, but not limited to,
        notification by electronic mail) of such proposed Underwritten Offering to
        the
        Holders and such notice shall offer the Holders the opportunity to include
        in
        such Underwritten Offering such number of Common
        Units (the “Included
        Registrable Securities”)
        as
        each such Holder may request in writing; provided,
        however,
        that if
        Atlas Energy has been advised by the Managing Underwriter that the inclusion
        of
        Registrable Securities for sale for the benefit of the Holders will have
        a
        material adverse effect on the price, timing or distribution of the Common
        Units
        in the Underwritten Offering, then the amount of Registrable Securities to
        be
        offered for the accounts of Holders shall be determined based on the provisions
        of Section
        2.02(b)
        of this
        Agreement.  The notice required to be provided in this Section
        2.02(a)
        to
        Holders shall be provided on a Business Day pursuant to Section
        3.01
        hereof
        and receipt of such notice shall be confirmed by such Holder.  Each such
        Holder shall then have three Business Days after receiving such notice to
        request inclusion of Registrable Securities in the Underwritten Offering. 
If no request for inclusion from a Holder is received within the specified
        time,
        such Holder shall have no further right to participate in such Underwritten
        Offering.  If, at any time after giving written notice of its intention to
        undertake an Underwritten Offering and prior to the closing of such Underwritten
        Offering, Atlas Energy shall determine for any reason not to undertake or
        to
        delay such Underwritten Offering, Atlas Energy may, at its election, give
        written notice of such determination to the Selling Holders and, (x) in the
        case
        of a determination not to undertake such Underwritten Offering, shall be
        relieved of its obligation to sell any Included Registrable Securities in
        connection with such terminated Underwritten Offering, and (y) in the case
        of a
        determination to delay such Underwritten Offering, shall be permitted to
        delay
        offering any Included Registrable Securities for the same period as the delay
        in
        the Underwritten Offering.  Any Selling Holder shall have the right to
        withdraw such Selling Holder’s request for inclusion of such Selling Holder’s
        Registrable Securities in such offering by giving written notice to Atlas
        Energy
        of such withdrawal up to and including the time of pricing of such
        offering.  Each Holder’s rights under this Section
        2.02(a)
        shall
        terminate when such Holder (together with any Affiliates of such Holder)
        holds
        less than $15 million, in aggregate, of Registrable Securities, based on
        the
        Average Purchase Price.  Notwithstanding the foregoing, any Holder may
        deliver written notice (an “Opt
        Out Notice”)
        to
        Atlas Energy requesting that such Holder not receive notice from Atlas Energy
        of
        any proposed Underwritten Offering; provided,
        that
        such Holder may later revoke any such notice.

    

     

    (b)  Priority
      of Rights. 
      If the Managing Underwriter or Underwriters of any proposed Underwritten
      Offering of Common Units included in an Underwritten Offering involving Included
      Registrable Securities advises Atlas Energy, or Atlas Energy reasonably
      determines, that the total amount of Registrable Securities that the Selling
      Holders and any other Persons intend to include in such offering exceeds the
      number that can be sold in such offering without being likely to have a material
      adverse effect on the price, timing or distribution of the Common Units offered
      or the market for the Common Units, then the Registrable Securities to be
      included in such Underwritten Offering shall include the number of Registrable
      Securities that such Managing Underwriter or Underwriters advises Atlas Energy,
      or Atlas Energy reasonably determines, can be sold without having such adverse
      effect, with such number to be allocated (i) first, to Atlas Energy, and (ii)
      second, pro rata among the Selling Holders who have requested participation
      in
      such Underwritten Offering.  The pro rata allocations for each such Selling
      Holder shall be the product of (a) the aggregate number of Registrable
      Securities proposed to be sold by all Selling Holders in such Underwritten
      Offering multiplied by (b) the fraction derived by dividing (x) the number
      of
      Registrable Securities owned on the Closing Date by such Selling Holder by
      (y)
      the aggregate number of Registrable Securities owned on the Closing Date by
      all
      Selling Holders participating in the Underwritten Offering.  All
      participating Selling Holders shall have the opportunity to share pro rata
      that
      portion of such priority allocable to any Selling Holder(s) not so
      participating.

    Section
      2.03  Underwritten
      Offering. 

     

    (a)  Request
      for Underwritten Offering.
      In the
      event that one or more Holders collectively holding greater than $75 million
      of
      Registrable Securities, based on the Average Purchase Price, elect to dispose
      of
      Registrable Securities under the Registration Statement (including a
      registration statement pursuant to Section 2.01(d)) pursuant to an Underwritten
      Offering, Atlas Energy shall retain underwriters, effect such sale though an
      Underwritten Offering, including entering into an underwriting agreement in
      customary form with the Managing Underwriter or Underwriters, which shall
      include, among other provisions, indemnities to the effect and to the extent
      provided in Section 2.08 and take all reasonable actions as are requested by
      the
      Managing Underwriter or Underwriters to expedite or facilitate the disposition
      of such Registrable Securities. Atlas Energy management shall participate in
      a
      roadshow or similar marketing effort on behalf of any such Holder or Holders
      if
      gross proceeds from such Underwritten Offering are reasonably expected to exceed
      $75 million. 

     

    (b)  Limitation
      on Underwritten Offerings.
      In
      connection with any and all rights granted hereunder to the Holders to cause
      Atlas Energy to engage underwriters to conduct an Underwritten Offering on
      behalf of the Holders, in no event shall Atlas Energy be required to do more
      than aggregate of four such Underwritten Offerings.

     

    (c)  General
      Procedures. 
      In connection with any Underwritten Offering under this Agreement, Atlas Energy
      shall be entitled to select the Managing Underwriter or Underwriters.  In
      connection with an Underwritten Offering contemplated by this Agreement in
      which
      a Selling Holder participates, each Selling Holder and Atlas Energy shall be
      obligated to enter into an underwriting agreement that contains such
      representations, covenants, indemnities and other rights and obligations as
      are
      customary in underwriting agreements for firm commitment offerings of
      securities.  No Selling Holder may participate in such Underwritten
      Offering unless such Selling Holder agrees to sell its Registrable Securities
      on
      the basis provided in such underwriting agreement and completes and executes
      all
      questionnaires, powers of attorney, indemnities and other documents reasonably
      required under the terms of such underwriting agreement.  Each Selling
      Holder may, at its option, require that any or all of the representations and
      warranties by, and the other agreements on the part of, Atlas Energy to and
      for
      the benefit of such underwriters also be made to and for such Selling Holder’s
      benefit and that any or all of the conditions precedent to the obligations
      of
      such underwriters under such underwriting agreement also be conditions precedent
      to its obligations.  No Selling Holder shall be required to make any
      representations or warranties to or agreements with Atlas Energy or the
      underwriters other than representations, warranties or agreements regarding
      such
      Selling Holder and its ownership of the securities being registered on its
      behalf, its intended method of distribution and any other representation
      required by Law.  If any Selling Holder disapproves of the terms of an
      underwriting, such Selling Holder may elect to withdraw therefrom by notice
      to
      Atlas Energy and the Managing Underwriter; provided,
      however,
      that
      such withdrawal must be made at a time up to and including the time of pricing
      of such Underwritten Offering.  No such withdrawal or abandonment shall
      affect Atlas Energy’s obligation to pay Registration Expenses.

    Section
      2.04  Sale
      Procedures. 
      In connection with its obligations under this Article II, Atlas Energy will,
      as
      expeditiously as possible:

     

    (a)  prepare
      and file with the Commission such amendments and supplements to the Registration
      Statement and the prospectus used in connection therewith as may be necessary
      to
      cause the Registration Statement to be effective and to keep the Registration
      Statement effective for the Effectiveness Period and as may be necessary to
      comply with the provisions of the Securities Act with respect to the disposition
      of all securities covered by the Registration Statement;

     

    (b)  furnish
      to each Selling Holder (i) as far in advance as reasonably practicable before
      filing the Registration Statement or any other registration statement
      contemplated by this Agreement or any supplement or amendment thereto, upon
      request, copies of reasonably complete drafts of all such documents proposed
      to
      be filed (including exhibits and each document incorporated by reference therein
      to the extent then required by the rules and regulations of the Commission),
      and
      provide each such Selling Holder the opportunity to object to any information
      pertaining to such Selling Holder and its plan of distribution that is contained
      therein and make the corrections reasonably requested by such Selling Holder
      with respect to such information prior to filing the Registration Statement
      or
      such other registration statement or supplement or amendment thereto, and (ii)
      such number of copies of the Registration Statement or such other registration
      statement and the prospectus included therein and any supplements and amendments
      thereto as such Persons may reasonably request in order to facilitate the public
      sale or other disposition of the Registrable Securities covered by such
      Registration Statement or other registration statement;

     

    (c)  if
      applicable, use its commercially reasonable efforts to register or qualify
      the
      Registrable Securities covered by the Registration Statement or any other
      registration statement contemplated by this Agreement under the securities
      or
      blue sky laws of such jurisdictions as the Selling Holders or, in the case
      of an
      Underwritten Offering, the Managing Underwriter, shall reasonably request;
      provided,
      however,
      that
      Atlas Energy will not be required to qualify generally to transact business
      in
      any jurisdiction where it is not then required to so qualify or to take any
      action which would subject it to general service of process in any such
      jurisdiction where it is not then so subject;

    (d)  promptly
      notify each Selling Holder and each underwriter of Registrable Securities,
      at
      any time when a prospectus relating thereto is required to be delivered by
      any
      of them under the Securities Act, of (i) the filing of the Registration
      Statement or any other registration statement contemplated by this Agreement
      or
      any prospectus to be used in connection therewith, or any amendment or
      supplement thereto, and, with respect to such Registration Statement or any
      other registration statement or any post-effective amendment thereto, when
      the
      same has become effective; and (ii) any written comments from the Commission
      with respect to any filing referred to in clause (i) and any written request
      by
      the Commission for amendments or supplements to the Registration Statement
      or
      any other registration statement or any prospectus or prospectus supplement
      thereto;

     

    (e)  immediately
      notify each Selling Holder and each underwriter of Registrable Securities,
      at
      any time when a prospectus relating thereto is required to be delivered under
      the Securities Act, of (i) the happening of any event as a result of which
      the
      prospectus or prospectus supplement contained in the Registration Statement
      or
      any other registration statement contemplated by this Agreement, as then in
      effect, includes an untrue statement of a material fact or omits to state any
      material fact required to be stated therein or necessary to make the statements
      therein not misleading in the light of the circumstances then existing; (ii)
      the
      issuance or threat of issuance by the Commission of any stop order suspending
      the effectiveness of the Registration Statement or any other registration
      statement contemplated by this Agreement, or the initiation of any proceedings

      with
      respect to the suspension of the qualification of any Registrable Securities
      for
      sale under the applicable securities or blue sky laws of any jurisdiction. 
Following the provision of such notice, Atlas Energy agrees to as promptly
      as
      practicable amend or supplement the prospectus or prospectus supplement or
      take
      other appropriate action so that the prospectus or prospectus supplement does
      not include an untrue statement of a material fact or omit to state a material
      fact required to be stated therein or necessary to make the statements therein
      not misleading in the light of the circumstances then existing and to take
      such
      other action as is necessary to remove a stop order, suspension, threat thereof
      or proceedings related thereto;

     

    (f)  upon
      request and subject to appropriate confidentiality obligations, furnish to
      each
      Selling Holder copies of any and all transmittal letters or other correspondence

      or
      other body having jurisdiction (including any domestic or foreign securities
      exchange) relating to such offering of Registrable Securities;

     

    (g)  in
      the
      case of an Underwritten Offering, furnish upon request, (i) an opinion of
      counsel for Atlas Energy dated the effective date of the applicable registration
      statement or the date of any amendment or supplement thereto, and a letter
      of
      like kind dated the date of the closing under the underwriting agreement, and
      (ii) a “cold comfort” letter, dated the date of the applicable registration
      statement or the date of any amendment or supplement thereto and a letter of
      like kind dated the date of the closing under the underwriting agreement, in
      each case, signed by the independent public accountants who have certified
      Atlas
      Energy’s financial statements included or incorporated by reference into the
      applicable registration statement, and each of the opinion and the “cold
      comfort” letter shall be in customary form and covering substantially the same
      matters with respect to such registration statement (and the prospectus and
      any
      prospectus supplement included therein) as are customarily covered in opinions
      of issuer’s counsel and in accountants’ letters delivered to the underwriters in
      Underwritten Offerings of securities and such other matters as such underwriters
      or Selling Holders may reasonably request;

     

    
      
        
        

      

      
        9

        
          

        

      

      
        
        

      

    

     

    (h)  otherwise
      use its commercially reasonable efforts to comply with all applicable rules
      and
      regulations of the Commission, and make available to its security holders,
      as
      soon as reasonably practicable, an earnings statement, which earnings statement
      shall satisfy the provisions of Section 11(a) of the Securities Act and Rule
      158
      promulgated thereunder;

     

    (i)  make
      available to the appropriate representatives of the Managing Underwriter and
      Selling Holders access to such information and Atlas Energy personnel as is
      reasonable and customary to enable such parties to establish a due diligence
      defense under the Securities Act; provided,
      however,
      that
      Atlas Energy need not disclose any such information to any such representative
      unless and until such representative has entered into or is otherwise subject
      to
      a confidentiality agreement with Atlas Energy satisfactory to Atlas Energy
      (including any confidentiality agreement referenced in Section 8.06 of the
      Purchase Agreement);

     

    (j)  cause
      all
      such Registrable Securities registered pursuant to this Agreement to be listed
      on each securities exchange or nationally recognized quotation system on which
      similar securities issued by Atlas Energy are then listed;

     

    (k)  use
      its
      commercially reasonable efforts to cause the Registrable Securities to be
      registered with or approved by such other governmental agencies or authorities
      as may be necessary by virtue of the business and operations of Atlas Energy
      to
      enable the Selling Holders to consummate the disposition of such Registrable
      Securities;

     

    (l)  provide
      a
      transfer agent and registrar for all Registrable Securities covered by such
      registration statement not later than the effective date of such registration
      statement;

     

    (m)  enter
      into customary agreements and take such other actions as are reasonably
      requested by the Selling Holders or the underwriters, if any, in order to
      expedite or facilitate the disposition of such Registrable
      Securities;

     

    (n)  If
      any
      Purchaser could reasonably be deemed to be an “underwriter,” as defined in
      Section 2(a)(11) of the Securities Act, in connection with the registration
      statement in respect of any registration of Registrable Securities of such
      Purchaser pursuant to this Agreement, and any amendment or supplement thereof
      (any such registration statement or amendment or supplement, a “Purchaser
      Underwriter Registration Statement”),
      then
      for a period of two years following the File Date, Atlas Energy will cooperate
      with such Purchaser in allowing such Purchaser to conduct customary
“underwriter’s due diligence” with respect to Atlas Energy and satisfy its
      obligations in respect thereof.  In addition, for a period of one year
      following the File Date at any Purchaser’s request, Atlas Energy will furnish to
      such Purchaser, on the date of the effectiveness of any Purchaser Underwriter
      Registration Statement and thereafter no more often than on a quarterly basis,
      (i) a letter, dated such date, from Atlas Energy’s independent certified public
      accountants in form and substance as is customarily given by independent
      certified public accountants to underwriters in an underwritten public offering,
      addressed to such Purchaser, (ii) an opinion, dated as of such date, of counsel
      representing Atlas Energy for purposes of such Purchaser Underwriter
      Registration Statement, in form, scope and substance as is customarily given
      in
      an underwritten public offering, including a standard “10b-5” opinion for such
      offering, addressed to such Purchaser and (iii) a standard officer’s certificate
      from the Chief Executive Officer and Chief Financial Officer of Atlas Energy
      addressed to such Purchaser.  Atlas Energy will also permit one legal
      counsel to such Purchaser(s) to review and comment upon any such Purchaser
      Underwriter Registration Statement at least five Business Days prior to its
      filing with the Commission and all amendments and supplements to any such
      Purchaser Underwriter Registration Statement within a reasonable number of
      days
      prior to their filing with the Commission and not file any Purchaser Underwriter
      Registration Statement or amendment or supplement thereto in a form to which
      such Purchaser’s legal counsel reasonably objects;

    (o)  Each
      Selling Holder, upon receipt of notice from Atlas Energy of the happening of
      any
      event of the kind described in Section
      2.04(e)
      of this
      Agreement, shall forthwith discontinue disposition of the Registrable Securities
      until such Selling Holder’s receipt of the copies of the supplemented or amended
      prospectus contemplated by Section
      2.04(e)
      of this
      Agreement or until it is advised in writing by Atlas Energy that the use of
      the
      prospectus may be resumed and has received copies of any additional or
      supplemental filings incorporated by reference in the prospectus, and, if so
      directed by Atlas Energy, such Selling Holder will, or will request the managing
      underwriter or underwriters, if any, to deliver to Atlas Energy (at Atlas
      Energy’s expense) all copies in their possession or control, other than
      permanent file copies then in such Selling Holder’s possession, of the
      prospectus covering such Registrable Securities current at the time of receipt
      of such notice; 

     

    (p)  If
      requested by a Purchaser, Atlas Energy shall: (i) as soon as practicable
      incorporate in a prospectus supplement or post-effective amendment such
      information as such Purchaser reasonably requests to be included therein
      relating to the sale and distribution of Registrable Securities, including
      information with respect to the number of Registrable Securities being offered
      or sold, the purchase price being paid therefor and any other terms of the
      offering of the Registrable Securities to be sold in such offering; (ii) as
      soon
      as practicable make all required filings of such prospectus supplement or
      post-effective amendment after being notified of the matters to be incorporated
      in such prospectus supplement or post-effective amendment; and (iii) as soon
      as
      practicable, supplement or make amendments to any Registration Statement;
      and

     

    (q)  Include
      in the plan of distribution section of a registrations statement the following
      language with respect to the selling unitholders:

     

    “The
      selling unitholders may enter into derivative transactions with third parties,
      or sell securities not covered by this prospectus to third parties in privately
      negotiated transactions. If the applicable prospectus supplement indicates,
      in
      connection with those derivatives, the third parties may sell securities covered
      by this prospectus and the applicable prospectus supplement, including in short
      sale transactions. If so, the third party may use securities pledged by the
      selling unitholders or borrowed from the selling unitholders or others to settle
      those sales or to close out any related open borrowings of Units, and may use
      securities received from the selling unitholders in settlement of those
      derivatives to close out any related open borrowings of Units.”

    Section
      2.05  Cooperation
      by Holders. 
      Atlas Energy shall have no obligation to include in the Registration Statement
      Registrable Securities of a Holder, or in an Underwritten Offering pursuant
      to
Section
      2.02
      Registrable Securities of a Selling Holder, who has failed to timely furnish
      such information that Atlas Energy determines, after consultation with counsel,
      is reasonably required to be furnished or conformed in order for the
      registration statement or prospectus supplement, as applicable, to comply with
      the Securities Act.

     

    Section
      2.06  Restrictions
      on Public Sale by Holders of Registrable Securities.
       For a period of 365 days from the Closing Date, each Holder of Registrable
      Securities agrees not to effect any public sale or distribution of the
      Registrable Securities for a period of up to 30 days following completion of
      an
      Underwritten Offering of equity securities by Atlas Energy (except as provided
      in this Section
      2.06);
      provided,
      however,
      that
      the duration of the foregoing restrictions shall be no longer than the duration
      of the shortest restriction generally imposed by the underwriters on the
      officers or directors or any other Unitholder of Atlas Energy on whom a
      restriction is imposed in connection with such public offering.  In
      addition, the provisions of this Section
      2.06
      shall
      not apply with respect to a Holder that (A) owns less than $25 million, in
      aggregate, of Registrable Securities based on the Average Purchase Price or
      (B)
      has delivered an Opt Out Notice to Atlas Energy pursuant to Section
      2.02(a)
      hereof;
      provided,
      however,
      the
      above shall not apply, in the case of a Purchaser that is a large multi-unit
      investment or commercial banking organization, to activities in the normal
      course of trading of units of such Purchaser other than the unit participating
      in this transaction so long as such other units are not acting on behalf of
      the
      unit participating in this transaction and have not been provided with
      confidential information regarding Atlas Energy by the unit participating in
      this transaction; provided
      further,
      with
      respect to Goldman, Sachs & Co., the restrictions contained in this
Section
      2.06
      shall
      only apply to the Goldman Sachs Principal Strategies Group, as currently
      configured, and shall not restrict or limit the activities of any area or
      division of Goldman, Sachs & Co. or any of its Affiliates, other than
      Goldman Sachs Principal Strategies Group, as currently configured.

    Section
      2.08  Indemnification.

     

    (a)  By
      Atlas Energy. 
      In the event of an offering of any Registrable Securities under the Securities
      Act pursuant to this Agreement, Atlas Energy will indemnify and hold harmless
      each Selling Holder thereunder, its Affiliates that own Registrable Securities
      and their respective directors and officers, and each underwriter, pursuant
      to
      the applicable underwriting agreement with such underwriter, of Registrable
      Securities thereunder and each Person, if any, who controls such Selling Holder
      or underwriter within the meaning of the Securities Act and the Exchange Act,
      and its directors and officers (collectively, the “Selling
      Holder Indemnified Persons”),
      against any losses, claims, damages, expenses or liabilities (including
      reasonable attorneys’ fees and expenses) (collectively, “Losses”),
      joint
      or several, to which such Selling Holder Indemnified Person may become subject
      under the Securities Act, the Exchange Act or otherwise, insofar as such Losses
      (or actions or proceedings, whether commenced or threatened, in respect thereof)
      arise out of or are based upon any untrue statement or alleged untrue statement
      of any material fact contained in the Registration Statement or any other
      registration statement contemplated by this Agreement, any preliminary
      prospectus, free writing prospectus or final prospectus contained therein,
      or
      any amendment or supplement thereof, arise out of or are based upon the omission
      or alleged omission to state therein a material fact required to be stated
      therein or necessary to make the statements therein (in the case of a
      prospectus, in light of the circumstances under which they were made) not
      misleading or arise out of or are based upon a Selling Holder being deemed
      to be
      an “underwriter,” as defined in Section 2(a)(11) of the Securities Act, in
      connection with the registration statement in respect of any registration of
      Atlas Energy’s securities, and will reimburse each such Selling Holder
      Indemnified Person for any legal or other expenses reasonably incurred by them
      in connection with investigating or defending any such Loss or actions or
      proceedings; provided,
      however,
      that
      Atlas Energy will not be liable in any such case if and to the extent that
      any
      such Loss arises out of or is based upon an untrue statement or alleged untrue
      statement or omission or alleged omission so made in strict conformity with
      information furnished by such Selling Holder Indemnified Person in writing
      specifically for use in the Registration Statement or such other registration
      statement, or prospectus supplement, as applicable.  Such indemnity shall
      remain in full force and effect regardless of any investigation made by or
      on
      behalf of such Selling Holder or any such Selling Holder, its directors or
      officers or any underwriter or controlling Person, and shall survive the
      transfer of such securities by such Selling Holder.

     

    
      
        
        

      

      
        13

        
          

        

      

      
        
        

      

    

     

    (b)  By
      Each Selling Holder. 
      Each Selling Holder agrees severally and not jointly to indemnify and hold
      harmless Atlas Energy, its directors and officers, and each Person, if any,
      who
      controls Atlas Energy within the meaning of the Securities Act or of the
      Exchange Act, and its directors and officers, to the same extent as the
      foregoing indemnity from Atlas Energy to the Selling Holders, but only with
      respect to information regarding such Selling Holder furnished in writing by
      or
      on behalf of such Selling Holder expressly for inclusion in the Registration
      Statement or any preliminary prospectus or final prospectus included therein,
      or
      any amendment or supplement thereto; provided,
      however,
      that
      the liability of each Selling Holder shall not be greater in amount than the
      dollar amount of the proceeds (net of any Selling Expenses) received by such
      Selling Holder from the sale of the Registrable Securities giving rise to such
      indemnification.

     

    (c)  Notice. 
      Promptly after receipt by an indemnified party hereunder of notice of the
      commencement of any action, such indemnified party shall, if a claim in respect
      thereof is to be made against the indemnifying party hereunder, notify the
      indemnifying party in writing thereof, but the omission so to notify the
      indemnifying party shall not relieve it from any liability which it may have
      to
      any indemnified party other than under this Section
      2.08. 
      In any action brought against any indemnified party, it shall notify the
      indemnifying party of the commencement thereof.  The indemnifying party
      shall be entitled to participate in and, to the extent it shall wish, to assume
      and undertake the defense thereof with counsel reasonably satisfactory to such
      indemnified party and, after notice from the indemnifying party to such
      indemnified party of its election so to assume and undertake the defense
      thereof, the indemnifying party shall not be liable to such indemnified party
      under this Section
      2.08
      for any
      legal expenses subsequently incurred by such indemnified party in connection
      with the defense thereof other than reasonable costs of investigation and of
      liaison with counsel so selected; provided,
      however,
      that,
      (i) if the indemnifying party has failed to assume the defense or employ counsel
      reasonably acceptable to the indemnified party or (ii) if the defendants in
      any
      such action include both the indemnified party and the indemnifying party and
      counsel to the indemnified party shall have concluded that there may be
      reasonable defenses available to the indemnified party that are different from
      or additional to those available to the indemnifying party, or if the interests
      of the indemnified party reasonably may be deemed to conflict with the interests
      of the indemnifying party, then the indemnified party shall have the right
      to
      select a separate counsel and to assume such legal defense and otherwise to
      participate in the defense of such action, with the reasonable expenses and
      fees
      of such separate counsel and other reasonable expenses related to such
      participation to be reimbursed by the indemnifying party as incurred. 
Notwithstanding any other provision of this Agreement, no indemnified party
      shall settle any action brought against it with respect to which it is entitled
      to indemnification hereunder without the consent of the indemnifying party,
      unless the settlement thereof imposes no liability or obligation on, and
      includes a complete and unconditional release from all liability of, the
      indemnifying party.

     

    (d)  Contribution. 
      If the indemnification provided for in this Section
      2.08
      is held
      by a court or government agency of competent jurisdiction to be unavailable
      to
      any indemnified party or is insufficient to hold them harmless in respect of
      any
      Losses, then each such indemnifying party, in lieu of indemnifying such
      indemnified party, shall contribute to the amount paid or payable by such
      indemnified party as a result of such Loss in such proportion as is appropriate
      to reflect the relative fault of the indemnifying party on the one hand and
      of
      such indemnified party on the other in connection with the statements or
      omissions which resulted in such Losses, as well as any other relevant equitable
      considerations; 

     

    
      
        
        

      

      
        14

        
          

        

      

      
        
        

      

    

     

    provided,
      however,
      that in
      no event shall such Selling Holder be required to contribute an aggregate amount
      in excess of the dollar amount of proceeds (net of Selling Expenses) received
      by
      such Selling Holder from the sale of Registrable Securities giving rise to
      such
      indemnification.  The relative fault of the indemnifying party on the one
      hand and the indemnified party on the other shall be determined by reference
      to,
      among other things, whether the untrue or alleged untrue statement of a material
      fact or the omission or alleged omission to state a material fact has been
      made
      by, or relates to, information supplied by such party, and the parties’ relative
      intent, knowledge, access to information and opportunity to correct or prevent
      such statement or omission.  The parties hereto agree that it would not be
      just and equitable if contributions pursuant to this paragraph were to be
      determined by pro rata allocation or by any other method of allocation which
      does not take account of the equitable considerations referred to herein. 
The amount paid by an indemnified party as a result of the Losses referred
      to in
      the first sentence of this paragraph shall be deemed to include any legal and
      other expenses reasonably incurred by such indemnified party in connection
      with
      investigating or defending any Loss which is the subject of this
      paragraph.  No person guilty of fraudulent misrepresentation (within the
      meaning of Section 11(f) of the Securities Act) shall be entitled to
      contribution from any Person who is not guilty of such fraudulent
      misrepresentation.

     

    (e)  Other
      Indemnification. 
      The provisions of this Section

    Section
      2.09  Rule
      144 Reporting. 
      With a view to making available the benefits of certain rules and regulations
      of
      the Commission that may permit the sale of the Registrable Securities to the
      public without registration, Atlas Energy agrees to use its commercially
      reasonable efforts to:

     

    (a)  make
      and
      keep public information regarding Atlas Energy available, as those terms are
      understood and defined in Rule 144 under the Securities Act, at all times from
      and after the date hereof;

     

    (b)  file
      with
      the Commission in a timely manner all reports and other documents required
      of
      Atlas Energy under the Securities Act and the Exchange Act at all times from
      and
      after the date hereof; and

     

    (c)  so
      long
      as a Holder owns any Registrable Securities, furnish, unless otherwise not
      available at no charge by access electronically to the Commission’s EDGAR filing
      system, to such Holder forthwith upon request a copy of the most recent annual
      or quarterly report of Atlas Energy, and such other reports and documents so
      filed as such Holder may reasonably request in availing itself of any rule
      or
      regulation of the Commission allowing such Holder to sell any such securities
      without registration.

     

    Section
      2.10  Transfer
      or Assignment of Registration Rights. 
      The rights to cause Atlas Energy to register Registrable Securities granted
      to
      the Purchasers by Atlas Energy under this Article II may be transferred or
      assigned by any Purchaser to one or more transferee(s) or assignee(s) of such
      Registrable Securities or by total return swap; provided,
      however,
      that,
      except with respect to a total return swap, (a) unless such transferee is an
      Affiliate of such Purchaser or another Purchaser, each such transferee or
      assignee holds Registrable Securities in the amount of $10 million, based on
      the
      Average Purchase Price, (b) Atlas Energy is given written notice prior to any
      said transfer or assignment, stating the name and address of each such
      transferee and identifying the securities with respect to which such
      registration rights are being transferred or assigned, and (c) each such
      transferee assumes in writing responsibility for its portion of the obligations
      of such Purchaser under this Agreement.

    Section
      2.11  Limitation
      on Subsequent Registration Rights. 
      From and after the date hereof, Atlas Energy shall not, without the prior
      written consent of the Holders of Registrable Securities, (i) enter into any
      agreement with any current or future holder of any securities of Atlas Energy
      that would allow such current or future holder to require Atlas Energy to
      include securities in any registration statement filed by Atlas Energy on a
      basis that is superior in any way to the piggyback rights granted to the
      Purchasers hereunder or (ii) grant registration rights to any other Person
      that
      would be superior to the Purchasers’ registration rights hereunder.

    Section
      3.05  Change
      of Control.
      Atlas
      Energy shall not merge, consolidate or combine with any other Person unless

      issued pursuant to such merger, consolidation or combination.

     

    Section
      3.06  Specific
      Performance. 
      Damages in the event of breach of this Agreement by a party hereto may be
      difficult, if not impossible, to ascertain, and it is therefore agreed that
      each
      such Person, in addition to and without limiting any other remedy or right
      it
      may have, will have the right to an injunction or other equitable relief in
      any
      court of competent jurisdiction, enjoining any such breach, and enforcing
      specifically the terms and provisions hereof, and each of the parties hereto
      hereby waives any and all defenses it may have on the ground of lack of
      jurisdiction or competence of the court to grant such an injunction or other
      equitable relief.  The existence of this right will not preclude any such
      Person from pursuing any other rights and remedies at law or in equity which
      such Person may have.

     

    Section
      3.07  Counterparts.

      principles of conflict of Laws.

     

    Section
      3.10  Severability
      of Provisions. 
      Any provision of this Agreement which is prohibited or unenforceable in any
      jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
      such prohibition or unenforceability without invalidating the remaining
      provisions hereof or affecting or impairing the validity or enforceability
      of
      such provision in any other jurisdiction.

     

    Section
      3.11  Entire
      Agreement. 
      This Agreement is intended by the parties as a final expression of their

      Presumption. 
      If any claim is made by a party relating to any conflict, omission or ambiguity
      in this Agreement, no presumption or burden of proof or persuasion shall be

      shall
      have any obligation hereunder and that, notwithstanding that one or more of

      Purchasers may be a corporation, partnership or limited liability company,

      the Purchasers or any former, current or future director, officer, employee,

      of
      any of the foregoing, whether by the enforcement of any assessment or by any
      legal or equitable proceeding, or by virtue of any applicable Law, it being
      expressly agreed and acknowledged that no personal liability whatsoever shall
      attach to, be imposed on or otherwise be incurred by any former, current or
      future director, officer, employee, agent, general or limited partner, manager,
      member, stockholder or Affiliate of any of the Purchasers or any former, current
      or future director, officer, employee, agent, general or limited partner,
      manager, member, stockholder or Affiliate of any of the foregoing, as such,
      for
      any obligations of the Purchasers under this Agreement or the Purchase Agreement

    March

    Mr.
      Adam
      Jackson

    

    Dear
      Adam:

     

    On
      behalf
      of Non-Invasive Monitoring Systems, Inc. (the "Company"), I am pleased to
      confirm our offer of employment to you in the capacity of Chief Financial
      Officer. We are confident that you will be an excellent addition to the Company
      and provide significant influence in achieving our goals. This employment letter
      sets forth the terms and conditions 

     

    1.    Position.
      You
      are
      being offered to serve in a full-time capacity as Chief Financial Officer.
      

     

    2.    Salary.
      Your
      annual salary is based on the SafeStitch compensation Agreement in which
      encompasses services for NIMS. 

     

    3.    Stock
      Options.
      Subject
      to the approval of the Company’s Board of Directors, you will be granted an
      option to purchase:

     

    Twenty
      thousand (20,000) shares of the Company’s common stock. These options will vest
      (per NIMS Options Program) equally over the next four years starting on the
      first anniversary of the grant date as described in your stock option agreement.
      

     

    The
      exercise price per share will be equal to the fair market value per share on
      the
      date the option is granted or on your first day of employment, whichever is
      later. The options will be subject to the terms and conditions contained in
      a
      stock option agreement to be entered into by you and the Company prior to the
      grant. 

     

    4.    Benefits.
      You
      will
      be entitled to participate in the SafeStitch benefit program. 

     

    5.    Vacation.
      You will
      be entitled to paid vacation each year and sick days and other holidays in
      accordance with the SafeStitch policies. 

     

    6.    Prior
      Employment.
      By
      accepting the terms of this agreement, you are representing and warranting
      to
      the Company that you are under no contractual commitments inconsistent with
      your
      proposed obligations to the Company. You are also representing and warranting
      to
      the company the accuracy of the contents of your resume. Any breach of this
      representation will result in the termination of your employment.

     

    7.    Period
      of Employment. Your
      employment with the Company will be “at will,” meaning that either you or the
      Company will be entitled to terminate your employment at any time and for any
      reason, with or without cause. This is the full and complete agreement between
      you and the Company on this term. Although your job duties, title, compensation
      and benefits, as well as the Company’s personnel policies and procedures, may
      change from time to time, the “at will” nature of your employment may only be
      changed in an express written agreement signed by you and a duly authorized
      officer of the Company.

      Activities.
      While
      you render services to the Company, you will not engage in any other gainful
      employment, business or activity without the written consent of the Company.
      While you render services to the Company, you also will not assist any person
      or
      organization in competing with the Company, in preparing to compete with the
      Company or in hiring any employees of the Company. 

     

    9.    Amendment
      and Governing Law.
      This
      letter agreement may not be amended or modified except by an express written
      agreement signed by you and a duly authorized officer of the Company. The terms
      of this letter agreement and the resolution of any disputes will be governed
      by
      the laws of the State of Florida. 

     

    This
      letter contains all of the terms of your employment with the Company and
      supersedes any prior understandings or agreements, whether oral or written,
      between you and the Company. 

     

    We
      hope
      that you find the foregoing terms acceptable and look forward to working with
      you. You may indicate your agreement with these terms and accept this offer
      by
      signing and dating both the enclosed duplicate original of this letter and
      returning it to me. As required by law, your employment with the Company is
      also
      contingent upon your providing legal proof of your identity and authorization
      to
      work in Canada. 

     

    This
      offer, if not accepted, will expire at the close of business (EDT) on March
      21,
      2008. We look forward to having you join us on March 31, 2008. If you have
      any
      questions, please call me at 305.575.4203.
