To whom it may concern:
The undersigned  hereby tenders to MPF-NY 2007, LLC; MPF Badger  Acquisition Co.
LLC; MPF Flagship Fund 11, LLC; MPF DeWaay Premier Fund 4, LLC (collectively the

$5 per Share,  less the amount of any dividends made or declared with respect to
the Shares between November 16, 2007 and the Expiration Date, and upon the other
terms and subject to the  conditions  set forth in the Offer to Purchase,  dated
November 16, 2007 (the "Offer to Purchase")  and in this Letter of  Transmittal,

constitute   the   "Offer").   Receipt  of  the  Offer  to  Purchase  is  hereby
acknowledged.  The undersigned  recognizes  that, if more than 79,649 Shares are
validly tendered prior to or on the Expiration Date and not properly  withdrawn,
the Purchasers will, upon the terms of the Offer,  accept for payment from among
those Shares  tendered prior to or on the Expiration Date 79,649 Shares on a pro
rata basis,  with adjustments to avoid purchases of certain  fractional  Shares,
based upon the number of Shares validly  tendered  prior to the Expiration  Date
and not withdrawn.Subject to and effective upon acceptance for payment of any of
the Shares tendered hereby,  the undersigned sells,  assigns,  and transfers to,
Purchasers  all right,  title,  and  interest  in and to such  Shares  which are
purchased pursuant to the Offer. The undersigned hereby irrevocably  constitutes
and appoints the  Purchasers  as the true and lawful agent and  attorney-in-fact
and proxy of the  undersigned  with respect to such  Shares,  with full power of
substitution (such power of attorney and proxy being deemed to be an irrevocable
power and proxy coupled with an  interest),  to deliver such Shares and transfer
ownership of such Shares,  on the books of the  Corporation,  together  with all
accompanying evidences of transfer and authenticity, to the Purchasers and, upon
acceptance  of the tender of such  Shares by the  Purchasers,  to  exercise  all
voting rights and to receive all benefits and  otherwise  exercise all rights of
beneficial  ownership  of such  Shares all in  accordance  with the terms of the
Offer.  Upon the purchase of Shares pursuant to the Offer, all prior proxies and
consents  given by the  undersigned  with respect to such Shares will be revoked
and no  subsequent  proxies or  consents  may be given (and if given will not be
deemed  effective).  In addition,  by executing this Letter of Transmittal,  the
undersigned assigns to the Purchasers all of the undersigned's rights to receive
dividends  from the  Corporation  with  respect  to Shares  which are  purchased

Expiration  Date and to change the address of record for such  dividends  on the
books of the Corporation. Upon request, the Seller will execute and deliver, and

Shares tendered hereby and has full power and authority to validly tender, sell,
assign, and transfer the Shares tendered hereby, and that when any such Shares

charges, encumbrances, conditional sales agreements, or other obligations
relating to the sale or transfer thereof, and such Shares will not be subject to
any adverse claim. Upon request, the undersigned will execute and deliver any
additional documents deemed by the Purchasers to be necessary or desirable to
complete the assignment, transfer, and purchase of Shares tendered hereby. The
undersigned understands that a tender of Shares to the Purchasers will
constitute a binding agreement between the undersigned and the Purchasers upon
the terms and subject to the conditions of the Offer. The undersigned recognizes
the right of the Purchasers to effect a change of dividend address to MacKenzie

undersigned recognizes that under certain circumstances set forth in the Offer
to Purchase, the Purchasers may not be required to accept for payment any of the
Shares tendered hereby. In such event, the undersigned understands that any
Letter of Transmittal for Shares not accepted for payment will be destroyed by
the Purchasers. All authority herein conferred or agreed to be conferred shall
survive the death or incapacity of the undersigned and any obligations of the
undersigned shall be binding upon the heirs, personal representatives,
successors and assigns of the undersigned. Except as stated in the Offer to
Purchase, this tender is irrevocable.

controversy arising out of or related to this agreement or a purchase of Shares
shall be resolved by binding arbitration in San Francisco, California before a
retired judge. The arbitration shall be administered by JAMS pursuant to its
Arbitration Rules and Procedures ("Rules"). If one party fails to respond within
twenty days after the other party mails a written list of arbitrators by either
agreeing to one of the proposed arbitrators or suggesting three or more
alternate arbitrators, the proposing party may select the arbitrator from among
its initial list and JAMS shall then appoint that arbitrator to preside over the
arbitration. If the parties are unable to agree on an arbitrator, the parties
shall select an arbitrator pursuant to the Rules. Where reasonable, the
arbitrator shall schedule the arbitration hearing within four months after being
appointed. The arbitrator must render a decision in writing, explaining the
legal and factual basis for decision as to each of the principal controverted
issues. The arbitrator's decision will be final and binding upon the parties. A
judgment upon any award may be entered in a court of competent jurisdiction.
Each party shall be responsible for advancing one-half of the costs of
arbitration, including all JAMS fees; provided that, in the award, the
prevailing party shall be entitled to recover all of its costs and expenses,
including reasonable attorneys' fees and costs, arbitrator fees, JAMS fees and
costs, and any attorneys' fees and costs incurred in compelling arbitration. The
parties are not waiving, and expressly reserve, any rights they may have under
federal securities laws, rules, and regulations. This agreement will be
interpreted, construed, and governed according to federal securities laws and
the laws of the State of California; provided that all matters relating to
arbitration shall be governed by the Federal Arbitration Act (9 U.S.C. Sections
1 et seq.).

                           (See Instruction 3 - Box B)
================================================================================

The person signing this Letter of Transmittal hereby certifies the following to
the Purchasers under penalties of perjury:

     (i) The TIN set forth in the  signature  box on the front of this Letter of
Transmittal  is the  correct  TIN  of the  Shareholder,  or if  this  box [ ] is
checked,  the  Shareholder has applied for a TIN. If the Shareholder has applied
for a TIN, a TIN has not been issued to the  Shareholder,  and  either:  (a) the
Shareholder  has  mailed or  delivered  an  application  to receive a TIN to the
appropriate  IRS Center or Social  Security  Administration  Office,  or (b) the
Shareholder  intends to mail or deliver an  application  in the near  future (it
being  understood  that  if  the  Shareholder  does  not  provide  a TIN  to the
Purchasers  within sixty (60) days, 31% of all  reportable  payments made to the
Shareholder  thereafter  will  be  withheld  until  a TIN  is  provided  to  the
Purchasers); and

     (ii)  Unless  this box [ ] is checked,  the  Shareholder  is not subject to
backup  withholding  either because the  Shareholder:  (a) is exempt from backup
withholding,  (b) has not  been  notified  by the IRS that  the  Shareholder  is
subject to backup  withholding  as result of a failure to report all interest or
dividends,  or (c) has been  notified  by the IRS that  such  Shareholder  is no
longer subject to backup withholding.

Note: Place an "X" in the box in (ii) if you are unable to certify that the
Shareholder is not subject to backup withholding.

                           (See Instruction 3 - Box C)
================================================================================

Under Section 1445(e)(5) of the Internal Revenue Code and Treas. Reg.
1.1445-11T(d), a transferee must withhold tax equal to 10% of the amount
realized with respect to certain transfers of shares of a Corporation if 50% or
more of the value of its gross assets consists of U.S. real property interests
and 90% or more of the value of its gross assets consists of U.S. real property
interests plus cash equivalents, and the holder of the shares is a foreign
person. To inform the Purchasers that no withholding is required with respect to
the Shareholder's interest in the Corporation, the person signing this Letter of
Transmittal hereby certifies the following under penalties of perjury:
                  (i) Unless this box [ ] is checked, the Shareholder, if an
individual, is a U.S. citizen or a resident alien for purposes of U.S. income
taxation, and if other than an individual, is not a foreign corporation, foreign
partnership, foreign estate, or foreign trust (as those terms are defined in the
Internal Revenue Code and Income Tax Regulations); (ii) the Shareholder's U.S.
social security number (for individuals) or employer identification number (for
non-individuals) is correctly printed in the signature box on the front of this
Letter of Transmittal; and (iii) the Shareholder's home address (for
individuals), or office address (for non-individuals), is correctly printed (or
corrected) on the front of this Letter of Transmittal. If a corporation, the
jurisdiction of incorporation is __________.

The person signing this Letter of Transmittal understands that this
certification may be disclosed to the IRS by the Purchasers and that any false
statements contained herein could be punished by fine, imprisonment, or both.

================================================================================

By checking this box [ ], the person signing this Letter of Transmittal hereby
certifies under penalties of perjury that the Shareholder is an "exempt foreign
person" for purposes of the backup withholding rules under the U.S. federal
income tax laws, because the Shareholder:
     (i)  Is  a  nonresident   alien   individual  or  a  foreign   corporation,
          partnership, estate, or trust;
     (ii) If an individual, has not been and plans not to be present in the U.S.
          for a total of 183 days or more during the calendar year; and
     (iii) Neither  engages,  nor plans to engage,  in a U.S.  trade or business
          that has effectively  connected gains from  transactions with a broker
          or barter exchange.





                                  INSTRUCTIONS

              Forming Part of the Terms and Conditions of the Offer

     1. Tender,  Signature Requirements;  Delivery.  After carefully reading and
     completing  this  Letter  of  Transmittal,  in  order  to  tender  Shares a
     Shareholder  must sign at the "X" on the  bottom of the first  page of this
     Letter  of  Transmittal  and  insert  the  Shareholder's  correct  Taxpayer
     Identification  Number  or  Social  Security  Number  ("TIN")  in the space
     provided below the signature.  The signature must  correspond  exactly with
     the name printed (or  corrected) on the front of this Letter of Transmittal
     without any change  whatsoever.  If this Letter of Transmittal is signed by
     the registered  Shareholder of the Shares, a Medallion  signature guarantee
     on this Letter of  Transmittal  will be obtained  for you by MPF. If Shares
     are  tendered  for the  account of a member firm of a  registered  national
     security exchange,  a member firm of the National Association of Securities
     Dealers, Inc. or a commercial bank, savings bank, credit union, savings and
     loan  association,  or trust company having an office,  branch or agency in
     the United States (each an "Eligible  Institution"),  a Medallion signature
     guarantee is also required.  In all other cases,  signatures on this Letter
     of Transmittal must be Medallion guaranteed by an eligible institution,  by
     completing  the  signature  guarantee  set forth in BOX A of this Letter of
     Transmittal,  but MPF will obtain this for you. If any tendered  Shares are
     registered in the names of two or more joint holders, all such holders must
     sign this Letter of Transmittal. If this Letter of Transmittal is signed by
     trustees,  administrators,   guardians,   attorneys-in-fact,   officers  of
     corporations,  or others acting in a fiduciary or representative  capacity,
     such  persons  should so  indicate  when  signing  and must  submit  proper
     evidence  satisfactory  to the Purchasers of their authority to so act. For
     Shares to be validly  tendered,  a  properly  completed  and duly  executed
     Letter of Transmittal,  together with any required signature  guarantees in
     BOX A, and any other documents required by this Letter of Transmittal, must
     be received by the  Depositary  prior to or on the  Expiration  Date at its
     address  or  facsimile  number  set  forth on the  front of this  Letter of
     Transmittal.  No  alternative,  conditional  or contingent  tenders will be
     accepted.  All  tendering  Shareholders  by  execution  of this  Letter  of
     Transmittal  waive any right to  receive  any notice of the  acceptance  of
     their tender.

     2. Transfer Taxes. The Purchasers will pay or cause to be paid all transfer
     taxes, if any,  payable in respect of Shares accepted for payment  pursuant
     to the Offer.

     3. U.S.  Persons.  A Shareholder who or which is a United States citizen or
     resident alien individual, a domestic corporation,  a domestic partnership,
     a  domestic  trust,  or a  domestic  estate  (collectively  "United  States
     persons")  as those  terms are  defined in the  Internal  Revenue  Code and
     Income Tax Regulations, should complete the following:

          Box B - Substitute  Form W-9. In order to avoid 31% federal income tax
          backup withholding, the Shareholder must provide to the Purchasers the
          Shareholder's   correct  Taxpayer   Identification  Number  or  Social
          Security Number ("TIN") in the space provided below the signature line
          and certify,  under penalties of perjury, that such Shareholder is not
          subject to such backup  withholding.  The TIN that must be provided is
          that of the  registered  Shareholder  indicated  on the  front of this
          Letter of Transmittal. If a correct TIN is not provided, penalties may
          be imposed by the Internal Revenue Service ("IRS"), in addition to the
          Shareholder being subject to backup withholding.  Certain Shareholders
          (including,  among others, all corporations) are not subject to backup
          withholding.   Backup   withholding  is  not  an  additional  tax.  If
          withholding  results  in an  overpayment  of  taxes,  a refund  may be
          obtained from the IRS.

          Box C -  FIRPTA  Affidavit.  To  avoid  potential  withholding  of tax
          pursuant  to  Section  1445  of  the  Internal   Revenue  Code,   each
          Shareholder  who or  which  is a  United  States  Person  (as  defined
          Instruction 3 above) must  certify,  under  penalties of perjury,  the
          Shareholder's  TIN and  address,  and  that the  Shareholder  is not a
          foreign  person.  Tax  withheld  under  Section  1445 of the  Internal
          Revenue Code is not an additional  tax. If  withholding  results in an
          overpayment of tax, a refund may be obtained from the IRS.

     4. Foreign  Persons.  In order for a  Shareholder  who is a foreign  person
     (i.e.,  not a United  States  Person as  defined  in 3 above) to qualify as
     exempt from 31% backup withholding,  such foreign Shareholder must certify,
     under  penalties  of  perjury,  the  statement  in BOX D of this  Letter of
     Transmittal  attesting to that foreign  person's status by checking the box
     preceding  such  statement.   However,  such  person  will  be  subject  to
     withholding of tax under Section 1445 of the Code.

     5.  Additional  Copies of Offer to  Purchase  and  Letter  of  Transmittal.
     Requests for  assistance or additional  copies of the Offer to Purchase and
     this Letter of  Transmittal  may be obtained from the Purchasers by calling
