wishes  to  sell and Buyer wishes to buy a portion as  Tenant  in
Common of Seller's interest in the Entire Property.

2. PROPERTY. The Property to be sold to Buyer in this transaction
consists of an undivided 3.7856 percentage interest (hereinafter,
simply  the  "Property")  as  Tenant  in  Common  in  the  Entire
Property.   (0.9222% from AEI Income & Growth  Fund  XXI  Limited
Partnership  and 2.8634% from AEI Net Lease Income & Growth  Fund

     escrow  in sufficient time to allow escrow to close  on  the
     closing date.

5.  CLOSING  DATE.  Escrow shall close on or before February  15,
2002.

6.  DUE  DILIGENCE. Buyer will have until the expiration  of  the
fifth  business day (The "Review Period") after delivery of  each
of  following items, to be supplied by Seller, to conduct all  of
its  inspections  and due diligence and satisfy itself  regarding
each  item, the Property, and this transaction.  Buyer agrees  to
indemnify and hold Seller harmless for any loss or damage to  the
Entire  Property or persons caused by Buyer or its agents arising

Purchase Agreement for Champps Americana Restaurant, Schaumburg IL

     (d) Lease (as further set forth in paragraph 11(a) below) of
     the Entire Property showing occupancy date, lease expiration
     date,  rent,  and  Guarantees, if any, accompanied  by  such
     tenant  financial statements as may have been provided  most
     recently to Seller by the Tenant and/or Guarantors.

     It is a contingency upon Seller's obligations hereunder that
two  (2)  copies of the Co-Tenancy Agreement in the form attached
hereto  duly executed by Buyer and AEI Net Lease Income &  Growth
Fund  XX Limited Partnership and dated on the escrow closing date
be delivered to the Seller on the closing date.

      Buyer may cancel this agreement for ANY REASON in its  sole
discretion  by  delivering a cancellation notice, return  receipt
requested,  to Seller and escrow holder before the expiration  of
the  Review  Period. Such notice shall be deemed  effective  only
upon receipt by Seller.

      If  Buyer  cancels this Agreement as permitted  under  this
Section,  except  for  any  escrow  cancellation  fees  and   any
liabilities  under  the first paragraph  of  section  6  of  this
agreement  (which will survive), Buyer (after execution  of  such
documents   reasonably  requested  by  Seller  to  evidence   the
termination  hereof) will have absolutely no  rights,  claims  or
interest  of  any  type in connection with the Property  or  this
transaction,  regardless  of any alleged  conduct  by  Seller  or
anyone else.

      Unless this Agreement is canceled by Buyer pursuant to  the
terms  hereof,  if Buyer fails to pay the Purchase  Price,  Buyer
irrevocably will be deemed to be in default under this Agreement.
Seller may, at its option, declare this Agreement null and  void,
in  which  event  Buyer  will be deemed  to  have  canceled  this
Agreement  and  relinquish all rights in and to the  Property  or
Seller may exercise its rights under Section 14 hereof.  If  this
Agreement  is  not canceled and the Purchase Price is  paid  when
required,  all  of Buyer's conditions and contingencies  will  be
deemed satisfied.

7.  ESCROW.  Escrow shall be opened by Seller upon acceptance  of
this  Agreement  by both parties. The escrow  holder  will  be  a
nationally-recognized escrow company selected by Seller.  A  copy
of this Agreement will be delivered to the escrow holder and will
serve  as  escrow instructions together with the escrow  holder's
standard instructions and any additional instructions required by
the  escrow  holder  to clarify its rights and  duties  (and  the
parties agree to sign these additional instructions). If there is
any conflict between these other instructions and this Agreement,
this Agreement will control.

8.   TITLE.  Closing will be conditioned on the  agreement  of  a
title  company selected by Seller to issue an Owner's  policy  of
title  insurance, dated as of the close of escrow, in  an  amount
equal  to  the  purchase  price, insuring  that  Buyer  will  own
insurable  title  to  the Property subject  only  to:  the  title
company's  standard exceptions; current real property  taxes  and
assessments;  survey  exceptions;  the  rights  of   parties   in
possession pursuant to the lease defined in paragraph  11  below;
all  matters of public record; and other items disclosed to Buyer
during the Review Period.

Buyer Initial: /s/ SSK
Purchase Agreement for Champps Americana Restaurant, Schaumburg IL

      Buyer shall be allowed five (5) days after receipt of  said
commitment  for examination and the making of any  objections  to
marketability thereto, said objections to be made in  writing  or
deemed  waived.  If any objections are so made, the Seller  shall
be  allowed eighty (80) days to make such title marketable or  in
the  alternative  to  obtain  a commitment  for  insurable  title
insuring over Buyer's objections.  If Seller shall decide to make
no  efforts to make title marketable, or is unable to make  title
marketable or obtain insurable title, (after execution  by  Buyer
of  such documents reasonably requested by Seller to evidence the
termination hereof) this Agreement shall be null and void and  of
no  further force and effect.  Seller has no obligation to  spend
any  funds  or make any effort to satisfy Buyer's objections,  if
any.

      Pending  satisfaction of Buyer's objections,  the  payments
hereunder  required shall be postponed, but upon satisfaction  of
Buyer's objections and within ten (10) days after written  notice
of  satisfaction of Buyer's objections to the Buyer, the  parties
shall perform this Agreement according to its terms.

9.   CLOSING COSTS.  Seller will pay one-half of escrow fees, the
cost  of  the  title  commitment and  any  brokerage  commissions
payable.   The  Buyer  will pay the cost of  issuing  a  Standard
Owners  Title Insurance Policy in the full amount of the purchase
price,  if  Buyer shall decide to purchase the same.  Buyer  will
pay  all  recording fees, transfer taxes and clerk's fees imposed
upon the recording of the deed, one-half of the escrow fees,  and
the cost of an update to the Survey in Sellers possession (if  an
update  is  required  by Buyer.)  Each party  will  pay  its  own
attorney's fees and costs to document and close this transaction.

10.  REAL ESTATE TAXES, SPECIAL ASSESSMENTS AND PRORATIONS.

     (a)  Because the Entire Property (of which the Property is a
     part) is subject to a triple net lease (as further set forth
     in  paragraph 11(a)(i), the parties acknowledge  that  there
     shall  be no need for a real estate tax proration.  However,
     Seller  represents  that to the best of its  knowledge,  all
     real  estate  taxes and installments of special  assessments
     due  and  payable in all years prior to the year of  Closing
     have been paid in full.  Unpaid real estate taxes and unpaid
     levied and pending special assessments existing on the  date
     of  Closing shall be the responsibility of Buyer and  Seller
     in   proportion  to  their  respective  Tenant   in   Common
     interests,  pro-rated, however, to the date of  closing  for
     the   period   prior  to  closing,  which   shall   be   the
     responsibility of Seller if Tenant shall not pay  the  same.
     Seller  and  Buyer  shall likewise pay  all  taxes  due  and
     payable   in   the  year  after  Closing  and   any   unpaid
     installments  of special assessments payable  therewith  and
     thereafter,  if  such  unpaid  levied  and  pending  special
     assessments and real estate taxes are not paid by any tenant
     of the Entire Property.

     (b)  All  income  and all operating expenses from the Entire
     Property  shall be prorated between the parties and adjusted
     by them as of the date of Closing.  Seller shall be entitled
     to all  income  earned  and  shall  be  responsible  for all
     expenses incurred prior  to  the  date of Closing, and Buyer
     shall be entitled to its proportionate  share  of all income
     earned and shall be responsible for its  proportionate share
     of all operating expenses of the Entire Property incurred on
     and after the date of closing.

11.  SELLER'S REPRESENTATION AND AGREEMENTS.

     (a)  Seller represents and warrants as of  this date that:

     (i)  Except for  the  Lease  Agreement in  existence  between  AEI
          Income & Growth Fund XXI  Limited Partnership, AEI Net  Lease
          Income & Growth  Fund  XX  Limited Partnership and  Net Lease
          Income & Growth Fund 84-A Limited Partnership (as "Landlord")
          and  Champps Americana, Inc. ("Tenant"), dated April 21, 1997
          and amended on December 31, 1997, and that Guarantee of Lease
          in existance between AEI Income & Growth  Fund  XXI   Limited
          Partnership, AEI Net Lease Income & Growth  Fund  XX  Limited
          Partnership  and  Net  Lease  Income  &  Growth Fund 84-A (as
          "Lessor") and  Champps Americana, Inc. (as "Guarantor") dated
          April 21,1997, Seller is not aware of any leases or guarantee
          of leases of  the  Property.   The  above  referenced   lease
          agreement has a right of first refusal in favor of the Tenant
          as set forth in Article 34 of  said  lease  agreement,  which
          right will apply to any attempted disposition  of Property by
          Buyer after this transaction.

     (ii) It is not aware of any pending litigation or condemnation
          proceedings against the Property or Seller's interest in the
          Property.

     (iii)Except  as previously disclosed to Buyer  and  as
          permitted in paragraph (b) below, Seller is not aware of any
          contracts Seller has executed that would be binding on Buyer
          after the closing date.

     (b)  Provided  that  Buyer performs  its  obligations  when
     required, Seller agrees that it will not enter into any  new
     contracts that would materially affect the Property  and  be
     binding  on  Buyer  after the Closing Date  without  Buyer's
     prior  consent,  which  will not be  unreasonably  withheld.
     However,  Buyer acknowledges that Seller retains  the  right
     both  prior to and after the Closing Date to freely transfer
     all or a portion of Seller's remaining undivided interest in
     the  Entire Property, provided such sale shall not  encumber
     the  Property being purchased by Buyer in violation  of  the
     terms hereof or the contemplated Co-Tenancy Agreement.

12.  DISCLOSURES.

     (a)   Seller  has not received any notice of  any  material,
     physical,  or  mechanical defects of  the  Entire  Property,
     including  without  limitation, the plumbing,  heating,  air
     conditioning, ventilating, electrical system. To the best of
     Seller's  knowledge without inquiry, all such items  are  in
     good  operating condition and repair and in compliance  with
     all  applicable  governmental, zoning, and  land  use  laws,
     ordinances,  regulations and requirements.  If Seller  shall
     receive any notice to the contrary prior to Closing,  Seller

     laws,  ordinances, regulations and requirements.  If  Seller
     shall  receive any notice to the contrary prior to  Closing,
     Seller will inform Buyer prior to Closing.

     (c)   Seller  knows  of no facts nor has  Seller  failed  to
     disclose  to  Buyer  any fact known to  Seller  which  would
     prevent  the  Tenant  from using and  operating  the  Entire
     Property after the Closing in the manner in which the Entire
     Property  has been used and operated prior to  the  date  of
     this  Agreement.  If Seller shall receive any notice to  the
     contrary prior to Closing, Seller will inform Buyer prior to
     Closing.

     (d)   Seller  has  not received any notice that  the  Entire
     Property is in violation of any federal, state or local law,

     Property,   including,  but  not  limited  to,   soil,   and
     groundwater conditions.  To the best of Seller's  knowledge,
     there  is  no  proceeding  or inquiry  by  any  governmental
     authority   with  respect  to  the  presence  of   Hazardous
     Materials  on  the  Entire  Property  or  the  migration  of
     Hazardous Materials from or to other property.  Buyer agrees
     that  Seller will have no liability of any type to Buyer  or
     Buyer's  successors,  assigns, or affiliates  in  connection
     with  any  Hazardous Materials on or in connection with  the
     Entire  Property  either before or after the  Closing  Date,
     except such Hazardous Materials on or in connection with the
     Entire Property arising out of Seller's gross negligence  or

     EXCEPT AS EXPRESSLY PROVIDED HEREIN.

     (f)    BUYER  ACKNOWLEDGES  THAT,  HAVING  BEEN  GIVEN   THE
     OPPORTUNITY  TO  INSPECT  THE  ENTIRE  PROPERTY   AND   SUCH
     FINANCIAL  INFORMATION ON THE LESSEE AND GUARANTORS  OF  THE
     LEASE AS BUYER OR ITS ADVISORS SHALL REQUEST, IF IN SELLER'S
     POSSESSION, BUYER IS RELYING SOLELY ON ITS OWN INVESTIGATION
     OF  THE  PROPERTY  AND  NOT ON ANY INFORMATION  PROVIDED  BY
     SELLER OR TO BE PROVIDED EXCEPT AS SET FORTH HEREIN.   BUYER
     FURTHER ACKNOWLEDGES THAT THE INFORMATION PROVIDED AND TO BE
     PROVIDED BY SELLER WITH RESPECT TO THE PROPERTY, THE  ENTIRE
     PROPERTY  AND  TO  THE LESSEE AND GUARANTORS  OF  LEASE  WAS
     OBTAINED  FROM A VARIETY OF SOURCES AND SELLER  NEITHER  (A)
     HAS  MADE INDEPENDENT INVESTIGATION OR VERIFICATION OF  SUCH

     contemplated  to  be performed, executed, and  delivered  by
     Buyer, Buyer shall perform, execute and deliver or cause  to
     be  performed,  executed, and delivered at  the  Closing  or

     consummate  the  transaction contemplated by this  Agreement
     and  has by proper proceedings duly authorized the execution
     and  delivery of this Agreement and the consummation of  the
     transaction contemplated hereby.

     (iii)   To  Buyer's  knowledge, neither  the  execution  and

     transaction  contemplated  hereby  will  violate  or  be  in
     conflict with (a) any applicable provisions of law, (b)  any
     order  of  any  court or other agency of  government  having
     jurisdiction  hereof, or (c) any agreement or instrument  to
     which Buyer is a party or by which Buyer is bound.

16.  DAMAGES, DESTRUCTION AND EMINENT DOMAIN.

     (a)   If, prior to closing, the Property or any part thereof
     be  destroyed  or further damaged by fire, the elements,  or
     any cause, due to events occurring subsequent to the date of
     this Agreement to the extent that the cost of repair exceeds
     $10,000.00,  this Agreement shall become null and  void,  at
     Buyer's  option exercised, if at all, by written  notice  to
     Seller within ten (10) days after Buyer has received written
     notice  from Seller of said destruction or damage.   Seller,
     however,  shall  have  the right to  adjust  or  settle  any
     insured  loss  until  (i)  all contingencies  set  forth  in
     Paragraph 6 hereof have been satisfied, or waived; and  (ii)
     any  ten-day  period provided for above in this Subparagraph
     16a  for  Buyer  to  elect to terminate this  Agreement  has

     Buyer's right to terminate this Agreement.  If Buyer  elects
     to  proceed  and  to  consummate the purchase  despite  said
     damage  or  destruction, there shall be no reduction  in  or
     abatement of the purchase price, and Seller shall assign  to
     Buyer the Seller's right, title, and interest in and to  all
     insurance  proceeds  (pro-rata in  relation  to  the  Entire
     Property) resulting from said damage or destruction  to  the
     extent  that the same are payable with respect to damage  to
     the  Property, subject to rights of any Tenant of the Entire
     Property.

     If  the cost of repair is less than $10,000.00, Buyer  shall
     be  obligated  to  otherwise  perform  hereinunder  with  no
     adjustment  to  the Purchase Price, reduction or  abatement,
     and  Seller shall assign Seller's right, title and  interest
     in and to all insurance proceeds pro-rata in relation to the
     Entire  Property,  subject to rights of any  Tenant  of  the
     Entire Property.

     (b)   If,  prior  to  closing, the  Property,  or  any  part
     thereof,  is  taken by eminent domain, this Agreement  shall
     become null and void, at Buyer's option.  If Buyer elects to
     proceed  and to consummate the purchase despite said taking,
     there  shall  be  no  reduction in,  or  abatement  of,  the
     purchase  price,  and  Seller  shall  assign  to  Buyer  the
     Seller's  right,  title, and interest in and  to  any  award
     made, or to be made, in the condemnation proceeding pro-rata
     in relation to the Entire Property, subject to rights of any
     Tenant of the Entire Property.

      In the event that this Agreement is terminated by Buyer  as
provided  above  in  Subparagraph 16a or  16b,  Buyer  agrees  to
execute such documents reasonably requested by Seller to evidence
the termination hereof.

17.  BUYER'S 1031 TAX FREE EXCHANGE.

      While  Seller  acknowledges that Buyer  is  purchasing  the
Property  as  "replacement property" to  accomplish  a  tax  free
exchange,   Buyer   acknowledges  that   Seller   has   made   no
representations,  warranties, or agreements to Buyer  or  Buyer's
agents  that  the transaction contemplated by the Agreement  will
qualify  for such tax treatment, nor has there been any  reliance
thereon by Buyer respecting the legal or tax implications of  the
transactions contemplated hereby.  Buyer further represents  that
it has sought and obtained such third party advice and counsel as
it  deems  necessary in regards to the tax implications  of  this
transaction.

      Buyer  wishes  to  novate/assign the ownership  rights  and
interest   of  this  Purchase  Agreement  to  Southwest  Exchange
Corporation  who  will act as Accommodator to  perfect  the  1031
exchange  by preparing an agreement of exchange of Real  Property
whereby  Southwest  Exchange Corporation will be  an  independent
third party purchasing the ownership interest in subject property
from  Seller  and  selling  the  ownership  interest  in  subject
property  to  Buyer  under  the  same  terms  and  conditions  as
documented  in this Purchase Agreement.  Buyer asks  the  Seller,
and  Seller  agrees  to cooperate in the perfection  of  such  an
exchange  if at no additional cost or expense to Seller or  delay
in time.  Buyer hereby indemnifies and holds Seller harmless from
any claims and/or actions resulting from said exchange.  Pursuant
to  the direction of Southwest Exchange Corporation, Seller  will
deed the property to Buyer.

18.  CANCELLATION

     If  any party elects to cancel this Contract because of  any
     breach by another party or because escrow fails to close  by
     the  agreed date, the party electing to cancel shall deliver
     to escrow agent a notice containing the address of the party
     in  breach and stating that this Contract shall be cancelled
     unless  the  breach  is cured within 13 days  following  the
     delivery  of  the notice to the escrow agent.  Within  three
     days  after  receipt of such notice, the escrow agent  shall
     send it by United States Mail to the party in breach at  the
     address contained in the Notice and no further notice  shall
     be  required. If the breach is not cured within the 13  days
     following  the  delivery of the notice to the escrow  agent,
     this Contract shall be cancelled.
