Group, Inc., a Michigan corporation ("Horizon") with and into Prime Retail, 
Inc., a Maryland corporation ("Prime") which was consummated on June 15, 1998 
("the Merger").  HGP's portfolio consists of 14 factory outlet centers and 
one power center located in 12 states comprising an aggregate of 
approximately 3,092,000 square feet of gross leasable area ("GLA").  Twelve 
of the factory outlet centers and the power center were contributed to the 
Company by Horizon immediately prior to the consummation of the Merger 
pursuant to a Contribution Agreement entered into in connection with the 
Merger (the "Contribution Agreement") and two factory outlet centers were 
purchased by the Company from Prime immediately subsequent to the 
consummation of the Merger.

Also in connection with the Merger and pursuant to the Amended and Restated 
Agreement and Plan of Merger dated as of February 1, 1998 by and among Prime, 
Horizon, HGP and other parties thereto (the "Merger Agreement"), the common 
shares of the Company were distributed to the holders of Prime common stock, 
Prime Series B Preferred stock, Prime Series C Preferred stock and Horizon 
common stock in accordance with the applicable exchange ratio for each such 
security.

The operations of the Company are primarily conducted through a subsidiary 
limited partnership, Horizon Group Properties, L.P. ("HGP LP") in which the 
Company is the sole general partner and, as of June 30, 1998, owns 
approximately 80% of the partnership interests (the "Common Units").  In 
connection with the Merger, the Common Units were distributed to the original 
holders (other than Prime) of partnership interests of a limited partnership 
affiliate of Prime and a limited partnership affiliate of Horizon, 
respectively, in accordance with the exchange ratios set forth in the Merger 
Agreement.  Common Units are exchangeable for shares of HGP common stock on a 
one-for-one basis at any time (or for an equivalent cash amount at the 
Company's election).

The Company owns Horizon's former administrative offices located in Norton 
Shores, Michigan and the following centers which were owned by Horizon prior 
to the Merger and contributed to the Company pursuant to the Contribution 
Agreement (collectively, such assets are referred to as the "Predecessor 
Properties" for periods prior to the Merger):

           Bellport Outlet Center in Patchogue, New York (held in joint
             ventures)
           Dry Ridge Outlet Center in Dry Ridge, Kentucky
           Horizon Outlet Center--Holland in Holland, Michigan
           Horizon Outlet Center--Laughlin in Laughlin, Nevada
           Horizon Outlet Center--Monroe in Monroe, Michigan
           Horizon Outlet Center--Somerset in Somerset, Pennsylvania
           Horizon Outlet Center--Traverse City in Traverse City, Michigan
           Horizon Outlet Center--Tulare in Tulare, California
           Lakeshore Marketplace in Norton Shores, Michigan
           Medford Outlet Center in Medford, Minnesota
           New Mexico Outlet Center in Algodones, New Mexico (vacant)
           Sealy Outlet Center in Sealy, Texas
           Warrenton Outlet Center in Warrenton, Missouri

Immediately after the Merger, the Company acquired the two properties listed
below.  Each property was purchased from an affiliate of Prime.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying unaudited consolidated and combined financial statements of 
the Company have been prepared in accordance with generally accepted 
accounting principles ("GAAP") for interim financial information and the 
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they 
do not include all of the information and footnotes required by GAAP for 
complete financial statements. In the opinion of management, the consolidated 
and combined financial statements contain all normal, recurring adjustments 
necessary for a fair statement of financial results for the interim period 
presented.  The preparation of these financial statements requires management 
to make estimates and assumptions that affect the amounts reported in the 
financial statements and accompanying notes.  Actual results could differ 
from these estimates.

STATEMENTS OF PREDECESSOR PROPERTIES

The financial statements for the dates and periods prior to the Merger reflect 
the results of operations, financial position, and cash flows of the 
Predecessor Properties prior to the Merger as if the Company had been a 
separate entity and owned such assets for all periods presented. The historical 
results of operations and financial condition of the Predecessor Properties are 
based on the manner in which Horizon historically managed such net assets. 
Accordingly, the combined condensed financial statements of the Predecessor 
Properties have been prepared using Horizon's historical basis of the assets 
and liabilities and historical results of operations related to the Predecessor 
Properties.  In this regard, because Horizon owned the Predecessor Properties, 
together with other properties which were not contributed to the Company prior 
to the Merger, the Predecessor Properties were not insulated from the 
obligations and commitments of Horizon. Certain assumptions relating to the 
allocation of cash and cash equivalents, debt and financing costs, interest 
expense and general and administrative expenses, all of which were historically 
aggregated by Horizon, have been made in the combined financial statements for 
the periods prior to the Merger. These statements have been combined based upon 
the historical common ownership and management of the outlet centers.

These statements include an allocation of the aggregate debt balances of 
Horizon (which had historically been secured by a pool of Horizon's assets) 
based upon the proportionate use of debt proceeds by the Predecessor Properties 
compared to Horizon's total historical portfolio of outlet centers. Financing 
costs were allocated based upon the same ratio. Interest expense has been 
estimated based upon the aforementioned proportionate debt balances and the 
historical weighted average interest rate incurred by Horizon on its debt 
balances. The allocation was made in this manner because management believes it 
best represented the use of funds borrowed during the periods presented and 
because allocating the debt in this manner results in the statements of 
operations of the Predecessor Properties reflecting the stand-alone interest 
cost of doing business.

General and administrative expenses of Horizon have been allocated to the 
Predecessor Properties based upon the ratio of GLA of the Predecessor 
Properties portfolio of outlet centers compared to Horizon's total historical 
portfolio of outlet centers.
 
Cash and cash equivalents have been included in the combined condensed 
financial statements of the Predecessor Properties based upon the respective 
periods' ratio of GLA of the Predecessor Properties compared to Horizon's total 
historical portfolio of outlet centers. Horizon considered all highly liquid 
investments with a maturity of three months or less when purchased to be cash 
and cash equivalents.
 
Net contributions (distributions) are the net amounts advanced from and repaid 
to Horizon. Excess cash flows have been reflected as being distributed back to 
Horizon. Net contributions represent Horizon's funding of the Predecessor 
Properties' development cost needs in excess of cash flows generated from the 
Predecessor Properties' operations.

<PAGE>

The aforementioned allocations may not reflect actual balances had the Company 
existed as a separate entity.

REAL ESTATE AND DEPRECIATION

The carrying values of the Predecessor Properties for the period prior to the 
Merger are stated at Horizon's historic cost, less accumulated depreciation. 
For the period subsequent to the Merger, the Predecessor Properties are stated 
on the books of the Company at fair value as of June 15, 1998, the date the 
Predecessor Properties were contributed to the Company, less accumulated 
depreciation. The two centers purchased from an affiliate of Prime are stated 
at their purchase prices less accumulated depreciation. The carrying values as 
of June 15, 1998 are preliminary. Costs incurred for the acquisition, 
development, construction and improvement of properties, as well as significant 
renovations and betterments to the properties, are capitalized. Maintenance and 
repairs are charged to expense as incurred. Interest costs incurred with 
respect to qualified expenditures relating to the construction of assets are 
capitalized during the construction period.

In accordance with FASB Statement No. 121, ACCOUNTING FOR THE IMPAIRMENT OF 
LONG-LIVED ASSETS AND FOR LONG-LIVED-ASSETS TO BE DISPOSED OF, the financial 
statements of HGP reflect impairment losses on long-lived assets used in 
operations when events and circumstances indicate that the assets might be 
impaired and the undiscounted cash flows estimated to be generated by those 
assets are less than the carrying amounts of those assets.  Impairment losses 
are measured as the difference between carrying value and fair value for 
assets to be held in the portfolio. For assets to be sold, impairment is 
measured as the difference between carrying value and fair value, less costs 
to dispose. Fair value is based on estimated cash flows discounted at a 
risk-adjusted rate of interest or a value derived from comparable sales 
transactions in the marketplace. 
 
Periodically, in the course of reviewing the performance of its outlet 
centers, management may determine that certain outlet centers no longer meet 
the parameters set forth for its operating properties and accordingly, such 
outlet centers will be classified as held for sale.  As of December 31, 1997 
and June 30, 1998 the Algodones, New Mexico outlet center is classified as 
held for sale.

REVENUE RECOGNITION

Leases with tenants are accounted for as operating leases. Minimum annual 
rentals are generally recognized on a straight-line basis over the term of the 
respective lease. Rents which represent basic occupancy costs, including fixed 
amounts and amounts computed as a function of sales, are classified as base 
rent.  Amounts which may become payable in addition to base rent and which are 
computed as a function of sales in excess of certain thresholds are classified 
as percentage rents. Expense recoveries based on common area maintenance 
expenses and certain other expenses are accrued in the period in which the 
related expense is incurred. For periods beginning on and after April 1, 1998, 
percentage rents are accrued on the basis of reported tenant sales only after 
the sales exceed the thresholds above which such rent is due.  For periods 
prior to April 1, 1998, percentage rents were accrued based upon an estimate of 
total rent expected to be collected for the year.  

OTHER REVENUE

Other revenue consists primarily of interest income and income related to 
marketing services that is recovered from tenants pursuant to lease 
agreements.

DEFERRED COSTS AND OTHER ASSETS

Leasing and deferred financing costs are capitalized at cost. Amortization is 
recorded on the straight-line method over the life of the lease or the debt, 
respectively.

INVESTMENT IN UNCONSOLIDATED JOINT VENTURES 

<PAGE>

The Company accounts for its investment in two joint ventures using the 
equity method of accounting.  Under this method of accounting, the net equity 
investment of the Company is reflected on the balance sheet and the 
statements of operations include the Company's share of the net income or 
loss from such joint ventures.

INCOME TAXES

Commencing with the year ending December 31, 1998, the Company intends to 
make an election to be taxed as a REIT under Sections 856 through 860 of the 
Internal Revenue Code of 1986, as amended.  As a REIT, the Company generally 
will not be subject to federal income tax if it distributes at least 95% of 
its taxable income for each tax year to its shareholders. REITs are subject 
to a number of organizational and operational requirements. If the Company 
fails to qualify as a REIT in any taxable year, the Company will be subject 
to federal income tax (including any applicable alternative minimum tax) on 
its taxable income at regular corporate tax rates. Even if the Company 
qualifies for taxation as a REIT, the Company may be subject to state and 
local income taxes and to federal income tax and excise tax on its 
undistributed income.

RECLASSIFICATIONS

Certain reclassifications have been made to the previously reported 
statements of the Predecessor Properties in order to provide comparability 
with the Company's statements reported herein.  These reclassifications have 
not changed the previously reported results.

NOTE 3 - EARNINGS PER SHARE

NOTE 4 - LONG TERM STOCK INCENTIVE PLAN

The Company has adopted the HGP 1998 Long Term Stock Incentive Plan (the "HGP 
Stock Plan") to advance the interests of the Company by encouraging and 
enabling the acquisition of a financial interest in the Company by key 
employees and officers of the Company and its subsidiaries through equity 
awards.  The Company reserved 338,900 common shares for issuance pursuant to 
the HGP Stock Plan, an amount equal to approximately 10% of the aggregate of 
the total outstanding common shares of the Company and outstanding Common 
Units of HGP LP as of June 15, 1998.

NOTE 5 - MORTGAGE DEBT AND OTHER LIABILITIES

On June 15, 1998, certain wholly owned affiliates of the Company entered into 
a credit facility (the "HGP Credit Facility") with Nomura Asset Capital 
Corporation ("Nomura") providing for initial borrowings of 

<PAGE>

$108,205,000. The HGP Credit Facility is guaranteed by HGP and HGP LP.  The HGP 
Credit Facility has a term of three years and bears interest at the 30-day 
LIBOR Rate (as defined in the HGP Credit Facility) plus 1.90% per annum. The 
HGP Credit Facility is cross-collateralized by mortgages on the Company's 12 
wholly owned outlet centers and one power center.  The HGP Credit Facility 
requires monthly payments of interest. In addition, the HGP Credit Facility 
requires principal payments totaling $1.5 million, $1.5 million and $2.0 
million during the first, second and third years, respectively, payable in 
equal monthly installments.  An additional principal payment of $2.2 million is 
due on September 1, 1998.  It is likely that in order to meet this obligation, 
the Company will borrow such amount from Prime, but Prime is not obligated to 
make any such loan to the Company.  The HGP Credit Facility has a prepayment 
penalty of 1% of amounts repaid during the first loan year and 2% of amounts 
repaid during the second and third loan years. The HGP Credit Facility contains 
restrictions on the ability of HGP and HGP LP to incur additional indebtedness, 
and under certain circumstances, requires the Company to enter into an interest 
rate lock arrangement which would fix the interest rate on the full outstanding 
amount of the HGP Credit Facility. 

In connection with the HGP Credit Facility, the Company established certain 
escrow accounts and cash collection accounts for the benefit of Nomura which 
are classified on the balance sheet of the Company as restricted cash.

Prime has guaranteed approximately $12.2 million of obligations under the HGP 
Credit Facility (the "Prime Guarantee"). In connection with the Prime 
Guarantee, HGP has agreed to pay Prime a fee of $400,000 per annum until the 
Prime Guarantee terminates. The Prime Guarantee will terminate if HGP raises 
at least $50.0 million in new capital and uses at least $50.0 million of the 
proceeds from such capital raised to reduce borrowings under the HGP Credit 
Facility.

The Company has loans totaling $3.04 million as of June 30, 1998 secured by a 
mortgage on the office building and related equipment which the Company 
utilizes as a corporate office in Norton Shores, Michigan.  This building was 
previously owned by an affiliate of Horizon and was contributed to the 
Company pursuant to the Contribution Agreement.  The consent of the lender to 
the previous owner of the property was required in connection with the 
transfer of the property to the Company. The Company is currently seeking 
such consent but as of August 14, 1998, such consent has not been obtained. 

HGP also has a $4.0 million revolving credit facility that matured on August 
1, 1998.  The outstanding balance at June 30, 1998 was $4.0 million. Prime 
has agreed to lend HGP sufficient funds, at a rate of 10% per annum, if HGP 
is otherwise unable to repay in full its obligations under such facility.  
HGP has also agreed that it will repay this replacement facility or other 
related indebtedness on which Prime is contingently liable to the extent of 
net proceeds from an equity offering or the sale of the Algodones, New Mexico 
Outlet Center.  The lender has verbally indicated that it is willing to 
extend the term of the loan through August 15, 1998 and perhaps through 
August 31, 1998 and is not currently seeking repayment of the facility. The 
Company is currently negotiating to replace this facility with another 
similar facility either from Prime or another lender.

Pursuant to the Contribution Agreement, the Company agreed to assume, 
undertake to pay, satisfy and discharge when due in accordance with their 
terms certain assumed liabilities (the "Assumed Liabilities"), which are 
defined to include all liabilities of Horizon which arise from the ownership 
and operation of the Predecessor Properties and include (i) all obligations 
to indemnify present and former officers and directors of Horizon under 
certificates or articles of incorporation, by-laws, partnership agreements, 
employment agreements, indemnification agreements or otherwise, for any 
matter existing or occurring after the Merger, (ii) all leases and related 
contracts, and service contracts, relating to any Contributed Asset (as 
defined in the Contribution Agreement) and (iii) certain other specified 
obligations. 

Also pursuant to the Contribution Agreement, certain partnership interests in 
two joint ventures, MG Patchogue Limited Partnership and MG Patchogue II 
Limited Partnership, which own the Bellport Factory Outlet Center, were 
transferred from an affiliate of Horizon to HGP LP and an affiliate of HGP 
LP.  The Company is currently seeking the consents of the limited partners to 
such transfers but as of August 14, 1998, such consents had not been 
obtained.  Additionally, the transfer of the general partnership interest in 
MG Patchogue Limited Partnership pursuant to the Contribution Agreement 
required the 

<PAGE>

consent of MG Patchogue Limited Partnership's mortgage lender.  The Company is 
currently seeking such consent but, as of August 14, 1998, such consent had not 
been obtained.  The Company accounts for its investment in these partnerships 
using the equity method of accounting.

MG Patchogue II Limited Partnership, of which the Company is 1% general 
partner and 44% limited partner, is subject to indebtedness totaling 
approximately $11.8 million which matures August 14, 1998.  Nomura has issued 
a commitment to lend the partnership $14 million under the HGP Credit 
Facility on or before September 1, 1998.  The consent of the limited partners 
is required in order to complete such financing with Nomura.  The Company is 
currently seeking such consent, but as of August 14, 1998 such consent had 
not been obtained. If completed, the Company will utilize the proceeds of 
such financing to repay the existing indebtedness and make the $2.2 million 
principal payment which is due September 1, 1998 under the HGP Credit 
Facility.  The Company accounts for its investment in this partnership 
using the equity method of accounting.

The Company can give no assurances that it will be able to obtain the above 
mentioned consents or that it will be able to finance or refinance its 
indebtedness as it matures or that any such financing will be obtained will 
be on favorable terms.  Any such failure to obtain such consents or such 
financings could have a material adverse effect upon the Company.

Prior to the Merger, Horizon entered into an agreement (the "PVH Agreement") 
with Phillips Van Heusen, Inc. ("PVH") which deleted or delayed the effective 
date of certain provisions of PVH leases in exchange for certain payments.  
Prime is liable for future payments relating to the PVH Agreement.  The Company 
is obligated to reimburse Prime for two payments relating to the PVH Agreement 
totaling $2,334,000, payable in the amounts of $1,167,000 on each of June 15, 
1999 and June 15, 2000.

NOTE 6 - RELATED PARTY TRANSACTIONS

The Company utilizes Thilman & Philippini as agent for its insurance and risk 
management programs.  E. Thomas Thilman is a Director of the Company and a 
partner in Thilman & Philippini.  During the period June 15, 1998 to June 30, 
1998, the Company paid premiums totaling approximately $200,000 on insurance 
policies placed by Thilman & Philippini.

The Company leases office space for its senior executives at 77 W. Wacker, 
Chicago, Illinois from Prime Group Realty Trust.  Prime Group Realty Trust is 
an affiliate of Michael W. Reschke, a Director of the Company.  

NOTE 7 - PRO FORMA INFORMATION

The Pro Forma Consolidated Condensed Statements of Operations for the six 
month periods ended June 30, 1997 and 1998 reflect the following 
transactions, which occurred June 15, 1998, as if they had occurred on 
January 1, 1997: (a) the acquisition of the Predecessor Properties and the two 
centers from Prime; (b) the entry into the HGP Credit Facility; and (c) the 
issuance of stock of HGP and Common Units.

The accompanying Pro Forma Consolidated Condensed Financial Statements are not 
necessarily indicative of the results which would actually have been obtained 
had the transactions described above been completed on the dates indicated or 
which may be obtained in the future.

NOTE 9 - WORKING CAPITAL AGREEMENT

In connection with the Merger, the Company entered into a Working Capital 
Agreement with Prime (the "Working Capital Agreement"). The Working Capital 
Agreement provides that Prime will transfer to the Company net working 
capital of $545,000. This amount is net of the current assets and current 
liabilities of the Predecessor Properties and the two centers which the 
Company purchased from Prime as of the date of the Merger. Prime transferred 
$3,000,000 to the Company at the closing of the Merger as a portion of the 
estimated amount due under the Working Capital Agreement. The Company has 
recorded a receivable from Prime for the balance of the amount due under the 
Working Capital Agreement. This amount is preliminary and is subject to 
Prime's review and approval but it is expected that the balance will be paid 
during the third quarter of 1998.

Item 2.  Management's Discussion and Analysis of Financial Condition and 
Results of Operations.

INTRODUCTION

The following discussion and analysis of the consolidated financial condition 
and results of operations of Horizon Group Properties, Inc. (together with 
its subsidiaries "HGP" or the "Company") and the Predecessor Properties (as 
herein after defined) should be read in conjunction with the Consolidated and 
Combined Condensed Financial Statements and Notes thereto. The Company's 
operations are conducted primarily through a subsidiary limited partnership, 
Horizon Group Properties, L.P. ("HGP LP").  The Company is the sole general 
partner of HGP LP and, as of June 30, 1998, owns approximately 80% of the 
HGP LP partnership interests ("Common Units"). Common Units of HGP LP are 
exchangeable for shares of HGP common stock on a one-for-one basis at any 
time (or for an equivalent cash amount at the Company's election).  The 
Company controls HGP LP and is dependent on distributions or other payments 
from HGP LP to meet its financial obligations.

CAUTIONARY STATEMENTS

The following discussion in "Management's Discussion and Analysis of 
Financial Condition and Results of Operations" contains certain 
forward-looking statements within the meaning of the Private Securities 
Litigation Reform Act of 1995 which reflect management's current views with 
respect to future events and financial performance.  Such forward-looking 
statements are subject to certain risks and uncertainties; including, but not 
limited to, the effects of future events on the Company's financial 
performance; the risk that the Company may be unable to finance its planned 
acquisition and development activities; risks related to the retail industry 
in which the Company's outlet centers compete, including the potential 
adverse impact of external factors, such as inflation, consumer confidence, 
unemployment rates and consumer tastes  and  preferences;  risks associated  
with  the Company's property  acquisitions,  such  as the  lack of 
predictability  with respect to financial  returns; risks associated  with 
the Company's  property  development  activities,  such as the  potential  
for  cost overruns,  delays and the lack of  predictability  with respect to 
the financial returns  associated  with these  development  activities;  the 
risk of potential increase in market interest rates from current levels; and 
risks associated with real estate ownership,  such as the potential adverse 
impact of changes in local economic climate on the revenues and the value of 
the Company's properties.  For further information on factors which could 
impact the Company and the statements contained herein, reference is made to 
the Company's other filings with the Securities and Exchange Commission, 
including the Company's Registration Statement on Form 10, as amended, dated 
as of June 4, 1998, with respect to the Company's initial registration of its 
common stock under the Securities Exchange Act of 1934, as amended and the 
Sky Merger Corp. Registration Statement on Form S-4, as filed with the 
Securities and Exchange Commission on May 12, 1998 (Registration No. 
333-51285).

GENERAL OVERVIEW

The Company is a self-administered and self-managed real estate investment trust
("REIT") that was established in connection with the merger of Horizon Group,
Inc., a Michigan corporation ("Horizon") with and into Prime Retail, Inc., a
Maryland corporation ("Prime") which was consummated on June 15, 1998 ("the
Merger").  HGP's portfolio consists of 14 factory outlet centers and one power
center located in 12 states comprising an aggregate of approximately 3,092,000
square feet of gross leasable area ("GLA").  Twelve of the factory outlet
centers and the power center were contributed to the Company immediately prior
to the consummation of the 

<PAGE>

Merger by Horizon pursuant to a Contribution Agreement entered into in 
connection with the Merger (the "Contribution Agreement") and two factory 
outlet centers were purchased by the Company from Prime immediately 
subsequent to the consummation of the Merger.

RESULTS OF OPERATIONS

The statements for the period June 15, 1998, the date of the Company's 
acquisition of the 12 outlet centers, one power center and Horizon's former 
administrative office from Horizon (the "Predecessor Properties") pursuant to 
the Contribution Agreement, through June 30, 1998 reflect the initial operation 
of the Company as a separate entity with its current assets.  The financial 
statements of the Company for the period June 15, 1998 to and as of June 30, 
1998 are not directly comparable to the statements of the Predecessor 
Properties for periods prior to the Merger due to a number of factors, 
including (1) a significant change in the indebtedness of the Company which 
occurred in conjunction with the Merger; (2) the acquisition by the Company of 
two additional outlet centers immediately after the Merger, the results of 
which are not included in the financial statements of the Predecessor 
Properties; (3) the fact that the outlet center in Algodones, New Mexico was 
substantially occupied during the periods presented prior to the Merger but was 
completely vacant during the period June 15, 1998 to June 30, 1998; and (4)  
the carrying value of the Predecessor Properties for the periods prior to the 
Merger are stated at Horizon's historic cost and depreciation expense is based 
on those costs.  For the period subsequent to the Merger, the Predecessor 
Properties are stated at the fair value as of the date of the Merger, resulting 
in a substantial decrease in value and a related decrease in depreciation 
expense. For these and other reasons, the combination of the results of 
operation for the periods prior to the Merger with those for the periods 
subsequent to the Merger is not indicative of the ongoing results of the 
Company for future periods.

The financial statements for the periods prior to the Merger reflect the 
results of operations, financial position, and cash flows of the Predecessor 
Properties prior to the Merger as if the Predecessor Properties had been a 
separate entity which owned such assets for all periods presented. The 
historical results of operations and financial condition of the Predecessor 
Properties are based on the manner in which Horizon historically managed such 
net assets. Accordingly, the combined condensed financial statements of the 
Predecessor Properties have been prepared using Horizon's historical basis of 
the assets and liabilities and historical results of operations related to 
the Predecessor Properties. In this regard, because Horizon owned the 
Predecessor Properties, together with other properties which were not 
contributed to the Company, the Predecessor Properties were not insulated from 
the obligations and commitments of Horizon.  Certain assumptions relating to 
the allocation of cash and cash equivalents, debt and financing costs, 
interest expense and general and administrative expenses, all of which were 
historically aggregated by Horizon, have been made in the combined financial 
statements for the periods prior to the Merger. See Note 2 to the Financial 
Statements. These statements have been combined based upon the historical 
common ownership and management of the outlet centers.

Rental revenue for the Predecessor Properties (excluding the Algodones, New 
Mexico Center which was vacant in 1998) for the six month period ended June 
30, 1998 increased 7% compared to the same period in the prior year.  Rental 
revenue for the Algodones, New Mexico center totaled $748,000 for the six 
months ended June 30, 1997.  Operating expenses and real estate taxes for the 
six months ended June 30, 1998 for the Predecessor Properties (excluding the 
Algodones, New Mexico center) decreased slightly less than 1% compared to the 
same period in the prior year.  Operating expenses and real estate taxes for 
the Algodones, New Mexico center were $273,000 for the six months ended June 
30, 1997.

Rental revenue for the Predecessor Properties (excluding the New Mexico 
center) for the three month period ended June 30, 1998 increased 6% compared 
to the same period in the prior year. Rental revenue for the New Mexico 
center totaled $363,000 for the three months ended June 30, 1997. Operating 
expenses and real estate taxes for the three months ended June 30, 1998 for 
the Predecessor Properties (excluding New Mexico) increased 8% compared to 
the same period in the prior year. Operating expenses for the New Mexico 
center were $117,000 for the three months ended June 30, 1997.

Average occupancy for the Predecessor Properties (excluding the Algodones, 
New Mexico Center) for the six month period ended June 30, 1998 was 73.8% 
compared to 75.37% for the same 

<PAGE>

period in the prior year.  Average occupancy for the Predecessor Properties 
(excluding the New Mexico center) for the three month period ended June 30, 
1998 was 76.08% compared to 73.98% for the same period in the prior year. As 
of June 30, 1998, occupancy of the Company's total operating portfolio was 
78.65%.

The Company operates primarily from the former headquarters of Horizon in 
Norton Shores, Michigan in an office building previously owned by Horizon and 
now owned by the Company.  All employees of the Company, with the exception 
of some of its senior management, were former employees of Horizon.  In 
connection with the Merger, a substantial number of former Horizon employees 
were either not offered employment with the Company or offered continued 
employment for a limited period of time.  The Company has currently leased a 
small portion of its office building to an unrelated tenant and is seeking 
additional tenants to occupy the space not required by the Company to 
accommodate its operations.  The Company also leases office space in Chicago 
for its senior management and leases office space in McLean, Virginia for its 
leasing staff.  The Company is currently seeking to cancel its lease in 
Virginia and relocate to smaller offices.  As a result of the above mentioned 
factors, among others, the general and administrative expenses of the Company 
for the period June 15, 1998 to June 30, 1998 are not necessarily 
representative of the expenses which will be incurred on an ongoing basis.

LIQUIDITY AND CAPITAL RESOURCES

As of June 30, 1998, the Company's outstanding mortgages and other debt was 
approximately $116 million.  While the Company is contemplating the expansion 
of the Tulare Outlet Center, during the remainder of 1998, the Company does not 
plan to expand its other outlet centers.  However, the Company does plan to 
spend approximately $3 million for tenant allowances, capital improvements and 
repairs to its outlet centers over the next twelve months, of which $1.2 
million will come from an escrow which was established at the closing of the 
HGP Credit Facility with Nomura (each as hereinafter defined). The Company 
plans to fund the remaining costs with existing cash balances and cash flow 
from operations.

In connection with the Merger, the Company entered into a Working Capital 
Agreement with Prime (the "Working Capital Agreement").  The Working Capital 
Agreement provides that Prime will transfer to the Company net working 
capital of $545,000.  This amount is net of the current assets and current 
liabilities of the Predecessor Properties and the two centers which the 
Company purchased from Prime as of the date of the Merger.  Prime transferred 
$3,000,000 to the Company at the closing of the Merger as a portion of the 
estimated amount due under the Working Capital Agreement.  The Company has 
recorded a receivable from Prime for the balance of the amount due  under the 
Working Capital Agreement. This amount is preliminary and is subject to 
Prime's review and approval but it is expected that the balance will be paid 
during the third quarter of 1998.

The Company expects to meet its short-term liquidity requirements generally 
through working capital and cash flows from operations.  The Company expects 
to meet its long-term requirements, such as tenant allowances for new leases 
and capital improvements, through the additional borrowing of long-term debt 
and the potential offering of equity securities in the private or public 
capital markets.  As a result of the Company's leverage, the Company's 
ability to obtain additional financing sources is limited. There can be no 
assurance that the Company will be able to successfully obtain such funding 
sources or, if obtained, on favorable terms.

On June 15, 1998, certain wholly owned affiliates of the Company entered into 
a credit facility (the "HGP Credit Facility") with Nomura Asset Capital 
Corporation ("Nomura") providing for initial borrowings of $108,205,000. The 
HGP Credit Facility is guaranteed by HGP and HGP LP.  The HGP Credit Facility 
has a term of three years and bears interest at the 30-day LIBOR Rate (as 
defined in the HGP Credit Facility) plus 1.90% per annum. The HGP Credit 
Facility is cross-

<PAGE>

collateralized by mortgages on the Company's 12 wholly owned outlet centers and 
one power center.  The HGP Credit Facility requires monthly payments of 
interest. In addition, the HGP Credit Facility requires principal payments 
totaling $1.5 million, $1.5 million and $2.0 million during the first, second 
and third years, respectively, payable in equal monthly installments.  An 
additional principal payment of $2.2 million is due on September 1, 1998.  It 
is likely that in order to meet this obligation, the Company will borrow such 
amount from Prime, but Prime is not obligated to make any such loan to the 
Company.  The HGP Credit Facility has a prepayment penalty of 1% of amounts 
repaid during the first loan year and 2% of amounts repaid during the second 
and third loan years. The HGP Credit Facility contains restrictions on the 
ability of HGP and HGP LP to incur additional indebtedness, and under certain 
circumstances, requires the Company to enter into an interest rate lock 
arrangement which would fix the interest rate on the full outstanding amount of 
the HGP Credit Facility. 

Prime has guaranteed approximately $12.2 million of obligations under the HGP 
Credit Facility (the "Prime Guarantee"). In connection with the Prime 
Guarantee, HGP has agreed to pay Prime a fee of $400,000 per annum until the 
Prime Guarantee terminates. The Prime Guarantee will terminate if HGP raises 
at least $50.0 million in new capital and uses at least $50.0 million of the 
proceeds from such capital raised to reduce borrowings under the HGP Credit 
Facility. 

The Company has loans totaling $3.04 million as of June 30, 1998 secured by a 
mortgage on the office building and related equipment which the Company 
utilizes as a corporate office in Norton Shores, Michigan.  This building was 
previously owned by an affiliate of Horizon and was contributed to the 
Company pursuant to the Contribution Agreement.  The consent of the lender to 
the previous owner of the property was required in connection with the 
transfer of the property to the Company. The Company is currently seeking 
such consent but as of August 14, 1998, such consent has not been obtained. 

HGP also has a $4.0 million revolving credit facility which matured on August 
1, 1998.  The outstanding balance at June 30, 1998 was $4.0 million. Prime 
has agreed to lend HGP sufficient funds, at a rate of 10% per annum, if HGP 
is otherwise unable to repay in full its obligations under such facility.  
HGP has also agreed that it will repay this replacement facility or other 
related indebtedness on which Prime is contingently liable to the extent of 
net proceeds from an equity offering or the sale of the Algodones, New Mexico 
Outlet Center.  The lender has verbally indicated that it is willing to 
extend the term of the loan through August 15, 1998 and perhaps through 
August 31, 1998 and is not currently seeking repayment of the facility. The 
Company is currently negotiating to replace this facility with another 
similar facility either from Prime or another lender.

The transfer of the general partnership interest in MG Patchogue Limited 
Partnership pursuant to the Contribution Agreement also required the consent 
of MG Patchogue Limited Partnership's mortgage lender. The Company is 
currently seeking such consent but, as of August 14, 1998, such consent had 
not been obtained.

MG Patchogue II Limited Partnership, of which the Company is 1% general 
partner and 44% limited partner, is subject to indebtedness totaling 
approximately $11.8 million which matures August 14, 1998.  Nomura has issued 
a commitment to lend the partnership $14 million under the HGP Credit 
Facility on or before September 1, 1998.  The consent of the limited partners 
is required in order to complete such financing with Nomura.  The Company is 
currently seeking such consent, but as of August 14, 1998 such consent had 
not been obtained. If completed, the Company will utilize the proceeds of 
such financing to repay the existing indebtedness and make the $2.2 million 
principal payment which is due September 1, 1998 under the HGP Credit 
Facility.

The Company can give no assurances that it will be able to obtain the above 
mentioned consents or that it will be able to finance or refinance its 
indebtedness as it matures or that any such financing will be obtained will 
be on favorable terms.  Any such failure to obtain such consents or such 
financings could have a material adverse effect upon the Company.

Prior to the Merger, Horizon entered into an agreement (the "PVH Agreement") 
with Phillips Van Heusen, Inc. ("PVH") which deleted or delayed the effective 
date of certain provisions of PVH leases for the benefit of Horizon in 
exchange for certain payments.  Prime is liable for future 

<PAGE>

payments relating to the PVH Agreement.  The Company is obligated to 
reimburse Prime for two payments relating to the PVH Agreement totaling 
$2,334,000, payable in the amounts of $1,167,000 on each of June 15, 1999 and 
June 15, 2000.

In order to qualify as a REIT for federal income tax purposes, the Company is 
required to pay dividends to its shareholders of at least 95% of its REIT 
taxable income in addition to satisfying other requirements.  Although the 
Company intends to make distributions to its shareholders in accordance with 
the requirements of the Internal Revenue Code of 1986, as amended, it also 
intends to retain such amounts as it considers necessary from time to time 
for the acquisition or development of new properties as suitable 
opportunities arise, for the expansion and renovation of its existing 
properties and for the retirement of debt.  As of June 30, 1998, HGP is not 
required to pay a dividend to its shareholders in order to be in compliance 
with the regulations applicable to REITs.

YEAR 2000

The Year 2000 Issue is the result of computer programs being written using 
two digits rather than four to define the applicable year.  Any of the 
Company's computer programs that have time-sensitive software may recognize a 
date using "00" as the year 1900 rather than the year 2000.  This could 
result in a system failure or miscalculations causing disruptions of 
operations, including, among other things, a temporary inability to process 
transactions, send invoices or engage in similar normal business activities.

The Company does not believe that the impact of the recognition of the year 
2000 by its information and operating technology systems will have a material 
adverse effect on the Company's financial condition and results of 
operations.  The majority of any necessary system changes will be 
accomplished and any upgrades made in the normal course of business.  The 
Company has initiated formal communications with all of its significant 
suppliers to determine the extent to which the Company's interface systems 
are vulnerable to those third parties' failure to remedy their own Year 2000 
issues.  There can be no guarantee that the systems of other companies, on 
which the Company's systems rely, will be timely converted and would not have 
an adverse effect on the Company's systems.

The Company has loans totaling $3.04 million as of June 30, 1998 secured by a 
mortgage on the office building and related equipment which the Company 
utilizes as a corporate office in Norton Shores, Michigan.  This building was 
previously owned by an affiliate of Horizon and was contributed to the Company 
pursuant to the Contribution Agreement.  The consent of the lender to the

facility.  The Company is currently negotiating to replace this facility with 
another similar facility.

The transfer of the general partnership interest in MG Patchogue Limited 
Partnership pursuant to the Contribution Agreement also required the consent 
of MG Patchogue Limited Partnership's mortgage lender. The Company is 
currently seeking such consent but, as of August 14, 1998, such consent had 
not been obtained.

MG Patchogue II Limited Partnership, of which the Company is 1% general partner 
and 44% limited partner, is subject to indebtedness totaling approximately 
$11.8 million which matures August 14, 1998.  Nomura has issued a commitment to 
lend the partnership $14 million under the HGP Credit Facility on or before 
September 1, 1998.  The consent of the limited partners is required in order to 
complete such financing with Nomura.  The Company is currently seeking such 
consent, but as of August 14, 1998 such consent had not been obtained.  If 
completed, the Company will utilize the proceeds of such financing to repay the 
existing indebtedness and make the $2.2 million principal payment which is due 
September 1, 1998 under the HGP Credit Facility.

The Company can give no assurances that it will be able to obtain the above 
mentioned consents or that it will be able to finance or refinance its 
indebtedness as it matures or that any such financing will be obtained will 
be on favorable terms.  Any such failure to obtain such consents or such 
financings could have a material adverse effect upon the Company.

                               EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as 
of this ____ day of June, 1998 by and between Horizon Group Properties, Inc., 
a Maryland corporation ("Employer") and Richard A. Berman, an individual 
domiciled in the State of Illinois ("Executive").

                                     WITNESSETH

     WHEREAS, Employer is engaged primarily in the ownership, development, 
construction, acquisition, leasing, marketing and management of factory 
outlet centers throughout the United States.

     WHEREAS, Employer believes that it would benefit from the application of 
Executive's particular and unique skill, experience, and background to its 
management and operation.

     WHEREAS, Executive wishes to commit himself to serve Employer in the 
position set forth herein on the terms herein provided.

     NOW,  THEREFORE, in consideration of the foregoing and the mutual 
covenants herein set forth, and for other good and valuable consideration, 
the receipt and sufficiency of which is hereby acknowledged by each of the 
parties hereto, Employer and Executive hereby agree as follows:

     1.   DUTIES.  During the Employment Term (as defined in Section 2), 
Employer agrees to employ Executive, and Executive agrees to be employed by 
Employer, as General Counsel of Employer on the terms and conditions provided 
in this Agreement.  Executive shall conduct, operate, manage and promote the 
business and business concept of Employer, and exercise such other powers and 
authority as are customarily inherent in a similar position in a comparable 
publicly-held entity or as provided by the By-laws of Employer ("By-laws").  
The Board of Directors of Employer (the "Board") may from time to time, in 
its sole discretion, further define and clarify Executive's duties and 
services hereunder or under the By-laws in a manner consistent with the 
offices for which he has been retained hereunder and the scope of work set 
forth herein.  Executive agrees to devote his best efforts and substantially 
all of his business time, attention, energy and skill to perform his duties 
under this Agreement.

     2.   TERM.  The initial term of this Agreement (the "Initial Term") 
shall commence on the closing date of the merger of Prime Retail, Inc. and 
Horizon Group, Inc. (the "Effective Date") and expire on the third 
anniversary of the Effective Date (the "Scheduled Termination Date"); 
provided, however, this Agreement shall automatically extend for one year 
terms following the Initial Term (each a "Renewal Term", together with the 
Initial Term, the "Employment Term"), unless either party shall give the 
other party, prior to 120 days before the end of the respective Renewal Term, 
written notice of its intention to terminate this Agreement.

                                       -1-
<PAGE>

     3.   COMPENSATION AND RELATED MATTERS.

     (a)  BASE SALARY.  During the Employment Term Employer agrees to pay to 
Executive an annual salary of no less than $145,000 ("Base Salary"), payable 
in accordance with the general policies and procedures for payment of 
salaries to any other executive personnel of Employer (but no less frequently 
than monthly), subject to withholding for applicable federal, state and local 
taxes. Executive's Base Salary shall be subject to periodic review by the 
Compensation Committee of the Board (the "Committee") based upon periodic 
review of Executive's performance conducted on at least an annual basis and 
may be periodically increased or decreased as a result thereof.

     (b)  PERFORMANCE BONUS.  In addition to Base Salary, Executive shall 
have the right to receive, and Employer agrees to pay to Executive, a 
performance bonus ("Performance Bonus") for each calendar year during the 
Employment Term, in such amounts as the Committee, in its sole discretion, 
may determine.  Any amount of Performance Bonus required to be paid to 
Executive for a calendar year during the Employment Term shall be paid by 
Employer to Executive during the pay period of Employer following 
finalization of the audit for such calendar year and final review and 
approval of the bonus calculation by the Committee, and, in all events, on or 
before April 15 of the year immediately following the end of the calendar 
year for which such Performance Bonus is attributable.

     (c)  BENEFITS.  During the Employment Term and subject to the 
limitations and affirmative rights set forth in this Section 3(c), Executive 
and his eligible dependents shall have the right to participate in any 
retirement, pension, life insurance, health, dental, vision and other medical 
insurance benefit plans or programs that have been or are hereafter adopted 
or maintained by Employer (or in which Employer participates) according to 
the terms of such plan or program with all of the benefits, rights and 
privileges as are enjoyed by any other senior executive officer of Employer.  
If  the participation of Executive would adversely affect the qualification 
of a plan intended to be qualified under the Internal Revenue Code of 1986, 
as amended (the "Code"), Employer shall have the right to exclude Executive 
from that plan in return for his participation in (x) a nonqualified deferred 
compensation plan or (y) an arrangement providing substantially comparable 
benefits under a plan that is either a qualified or nonqualified plan under 
the Code at Employer's option.

     (d)  VACATION AND LEAVES OF ABSENCE.  Executive shall be entitled to 
four weeks of paid vacation leave during each 12 month period and paid 
holidays in accordance with Employer's established policies. Executive may 
accrue unused vacation time if not used in any calendar year or years, 
however, the maximum cumulative amount of vacation time that Executive may 
accrue and carry over to the next year is four weeks. In addition to the 
foregoing, Executive may be granted leaves of absence with or without pay for 
such other reasons as shall be mutually agreed upon by the Board and 
Executive.

     (e)  EXPENSES.  Executive shall be reimbursed, subject to Employer's 
receipt of invoices or similar records as Employer may reasonably request in 
accordance with its policy and procedures, 

                                       -2-
<PAGE>

for all reasonable and necessary expenses incurred by Executive in the 
performance of his duties hereunder.

     4.   TERMINATION AND TERMINATION BENEFITS.

     (a)  TERMINATION BY EMPLOYER.

          (i)  WITHOUT CAUSE.  Employer may terminate this Agreement and 
Executive's employment at any time for any reason or for no reason at all 
upon 30 days' prior written notice to Executive.  In connection with the 
termination of Executive's services pursuant to this Section 4(a)(i), 
Executive shall be entitled to receive (A) all accrued but unpaid amounts of 
the Base Salary through the effective date of termination, payable in 
accordance with the provisions of Section 3(a); (B) a pro rata portion of any 
Performance Bonus otherwise payable to Executive for the calendar year in 
which such termination occurs up to the effective date of such termination 
and, to the extent not previously paid, any Performance Bonus for any 
calendar years prior to the calendar year in which such termination occurs; 
(C) a termination distribution in an amount equal to the amount of the Base 
Salary then applicable (the "Normal Termination Distribution"), payable 
within 30 days of the effective date of termination; and (D) any vested 
benefits or amounts pursuant to Sections 3(c), 3(d), 3(e) and 3(f) through 
the effective date of termination, payable in accordance with the provisions 
of any such plan(s).  In addition, Executive and his eligible dependents 
shall be entitled to receive (x) the health insurance benefits specified in 
Section 3(c) for a period of 12 months following the effective date of 
termination (the "Company Continuation Period"), and following such time 
period, Executive shall be entitled to all rights afforded to him under the 
federal Consolidated Omnibus Budget Reconciliation Act ("COBRA") to purchase 
continuation coverage of such health insurance benefits for himself and his 
dependents for the maximum period permitted by law and (y) the life insurance 
benefits specified in Section 3(f) for a period of 12 months following the 
effective date of termination.  With respect to clause (x) of the preceding 
sentence, to the extent required by applicable law, Executive shall be deemed 
to have elected to exercise his rights under COBRA as of the first day of the 
Company Continuation Period. In the event that Executive is terminated 
without Cause pursuant to this Section 4(a)(i) and within 12 months from the 
effective date of such termination there is a Change in Control of Employer 
(as defined below), then Executive shall be entitled to receive the benefits 
set forth in Section 4(e) to the extent and in the amount that such benefits 
exceed the amounts paid or received by Executive pursuant to this Section 
4(a)(i).  For purposes of calculating Executive's pro rata portion of any 
Performance Bonus, if termination takes place prior to receipt by Executive 
of any Performance Bonus, the Performance Bonus a pro rata portion of which 
Executive shall be entitled to receive shall be deemed to be 50% of 
Executive's then annual Base Salary.

          (ii) FOR CAUSE.  Employer may terminate this Agreement for Cause 
immediately upon written notice to Executive. In connection with the 
termination of Executive's services pursuant to this Section 4(a)(ii), 
Executive shall (A) be entitled to receive all accrued but unpaid amounts of 
the Base Salary through the effective date of termination, payable in 
accordance with the provisions of Section 3(a); (B) forfeit his entitlement 
to any bonuses or other payments otherwise payable to him in accordance with 
Section 3(b); and (C) be entitled to the vested benefits or amounts pursuant 

                                       -3-
<PAGE>

to Sections 3(c), 3(d), 3(e) and 3(f) through the effective date of 
termination, payable as otherwise provided in such sections; provided, 
however, that Executive and his eligible dependents shall be entitled to 
receive (x) the health insurance benefits specified in Section 3(c)(1) for a 
period of three months (the "Company Continuation Period") following the 
effective date of termination, and following such time period, Executive 
shall be entitled to all rights afforded to him under COBRA to purchase 
continuation coverage of such health insurance benefits for himself and his 
dependents for the maximum period permitted by law and (y) the life insurance 
benefits specified in Section 3(f) for a period of three months following the 
effective date of termination. With respect to clause (x) of the preceding 
sentence, to the extent required by applicable law, Executive shall be deemed 
to have elected to exercise his rights under COBRA as of the first day of the 
Company Continuation Period. 

          For purposes of this Agreement, "Cause" shall mean a finding by the 
Board (A) that Executive has materially harmed Employer through an act of 
dishonesty or material conflict of interest that relates to the performance 
of Executive's duties hereunder, (B) of Executive's conviction of a felony 
involving moral turpitude, fraud or embezzlement, (C) that Executive failed 
to perform in any material respect his duties under this Agreement (other 
than a failure due to disability) after written notice specifying the failure 
and a reasonable opportunity to cure (it being understood that if Executive's 
failure to perform is not of a type requiring a single action to fully cure, 
then Executive may commence the cure promptly after such written notice and 
thereafter diligently prosecute such cure to completion) or (D) of a material 
breach by Executive of any of his obligations hereunder and the failure of 
Executive to cure such breach within thirty (30) days after receipt by 
Executive of a written notice of Employer specifying in reasonable detail the 
nature of the breach.

          (iii)     DISABILITY.  If due to illness, physical or mental 
disability, or other incapacity, Executive shall fail during any four 
consecutive months to perform the duties required by this Agreement, Employer 
may terminate this Agreement upon 30 days' written notice to Executive.  In 
such event, Executive shall receive (A) all accrued but unpaid amounts of the 
Base Salary through the effective date of termination, payable in accordance 
with the provisions of Section 3(a); (B) a pro rata portion of any 
Performance Bonus otherwise payable to Executive for the calendar year in 
which such termination occurs up to the effective date of such termination 
and, to the extent not previously paid, any Performance Bonus for any 
calendar years prior to the calendar year in which such termination occurs; 
(C) the Normal Termination Distribution (defined in Section 4(a)(i)), payable 
within 30 days of the effective date of termination; and (D) any vested 
benefits or amounts pursuant to Sections 3(c), 3(d), 3(e) and 3(f) hereof 
through the effective date of termination, payable in accordance with the 
provisions of any such plan(s).  In addition, Executive and his eligible 
dependents shall be entitled to receive (x) the health insurance benefits 
specified in Section 3(c)(1) above for a period of 12 months (the "Company 
Continuation Period") following the effective date of termination and 
following such time period, Executive shall be entitled to all rights 
afforded to him under COBRA to purchase continuation coverage of such health 
insurance benefits for himself and his dependents for the maximum period 
permitted by law and (y) the life insurance benefits specified in Section 
3(f) for a period of 12 months following the date of termination. With 
respect to clause (x) of the preceding sentence, to the extent required by 
applicable law, Executive shall be deemed to have elected to exercise his 
rights under COBRA as of the first day of the Company 

                                       -4-
<PAGE>

Continuation Period.  This Section 4(a)(iii) shall not limit the entitlement 
of Executive, his estate or beneficiaries to any disability or other benefits 
available to Executive under any disability insurance or other benefits plan 
or policy that is maintained by Employer for Executive's benefit.  For 
purposes of calculating Executive's pro rata portion of any Performance 
Bonus, if termination takes place prior to receipt by Executive of any 
Performance Bonus, the Performance Bonus a pro rata portion of which 
Executive shall be entitled to receive shall be deemed to be 50% of 
Executive's then annual Base Salary.

     (b)   TERMINATION BY EXECUTIVE.

          (i)  WITH GOOD REASON.  Executive may terminate this Agreement with 
Good Reason upon written notice to Employer.  In connection with the 
termination of this Agreement pursuant to this Section 4(b)(i), Executive 
shall be entitled to receive (A) all accrued but unpaid amounts of the Base 
Salary through the effective date of termination, payable in accordance with 
the provisions of Section 3(a); (B) a pro rata portion of any Performance 
Bonus otherwise payable to Executive for the calendar year in which such 
termination occurs up to the effective date of such termination and, to the 
extent not previously paid, any Performance Bonus for any calendar years 
prior to the calendar year in which such termination occurs; (C) any vested 
benefits or amounts pursuant to sections 3(c), 3(d), 3(e) and 3(f) hereof 
through the effective date of termination, payable as otherwise provided in 
such sections.  In addition, the Executive and his eligible dependents shall 
be entitled to receive (x) the health insurance benefits specified in Section 
3(c)(1) for a period of 12 months following the effective date of termination 
(the "Company Continuation Period") and following such time period, the 
Executive shall be entitled to all rights afforded to him under COBRA to 
purchase continuation coverage of such health insurance benefits for himself 
and his dependents for the maximum period permitted by law and (y) the life 
insurance benefits specified in Section 3(f) for a period of 12 months 
following the date of termination. With respect to clause (x) of the 
preceding sentence, to the extent required by applicable law, Executive shall 
be deemed to have elected to exercise his rights under COBRA as of the first 
day of the Company Continuation Period.  Further, in connection with the 
termination of Executive's services pursuant to this Section 4(b)(i), 
Executive shall be entitled to receive the Normal Termination Distribution 
(defined in Section 4(a)(i)), payable within 30 days of the effective date of 
termination.  For purposes of calculating Executive's pro rata portion of any 
Performance Bonus, if termination takes place prior to receipt by Executive 
of any Performance Bonus, the Performance Bonus a pro rata portion of which 
Executive shall be entitled to receive shall be deemed to be 50% of 
Executive's then annual Base Salary.

          (ii) WITHOUT GOOD REASON. Executive may terminate this Agreement at 
any time for any reason or for no reason at all upon 60 days' written notice 
to Employer, during which period Executive shall continue to perform his 
duties under this Agreement if Employer so elects.  In connection with the 
termination of Executive's services pursuant to this Section 4(b)(ii), 
Executive shall be entitled to receive (A) all accrued but unpaid amounts of 
the Base Salary through the effective date of termination, paid in accordance 
with the provisions of Section 3(a); and (B) the vested benefits and amounts 
set forth in Sections 3(c), 3(d), 3(e) and 3(f) through the effective date of 
termination, payable in accordance with the provisions of such sections.  In 
addition, the 

                                       -5-
<PAGE>

Executive and his eligible dependents shall be entitled to receive (x) the 
health insurance benefits specified in Section 3(c)(1) for a period of six 
months (the "Company Continuation Period") following the effective date of 
termination and following such time period, the Executive shall be entitled 
to all rights afforded to him under COBRA to purchase continuation coverage 
of such health insurance benefits for himself and his dependents for the 
maximum period permitted by law and (y) the life insurance benefits specified 
in Section 3(f) for a period of three months following the date of 
termination.  With respect to clause (x) of the preceding sentence, to the 
extent required by applicable law, Executive shall be deemed to have elected 
to exercise his rights under COBRA as of the first day of the Company 
Continuation Period.

          (iii)     GOOD REASON.  For purposes of this Agreement, "Good 
Reason" shall mean (A) the material breach by Employer of any of its 
obligations hereunder (a bona fide dispute regarding the Performance Bonus 
shall not be a material breach by Employer) and the failure of Employer to 
cure such breach within 60 days after receipt by Employer of a written notice 
from Executive specifying in reasonable detail the nature of the breach, 
unless such breach requires a longer period to cure; (B) Executive's title or 
scope of responsibilities and duties are materially diminished, or the 
Company fails to provide Executive with adequate office facilities and 
support services to perform such responsibilities and duties, (C) the amounts 
payable to Executive as provided in this Agreement are materially reduced, or 
(D) the Company fails to continue in effect any cash or stock-based incentive 
or bonus plan, retirement plan, welfare benefit plan, or other benefit plan, 
program or arrangement, unless the aggregate value (as computed by an 
independent employee benefits consultant) of all such compensation, 
retirement and benefit plans, programs and arrangements provided to Executive 
is not materially less than their aggregate value as of the date of this 
Agreement (or as of the Change of Control, if greater).

     (c)  DEATH.  Notwithstanding any other provision of this Agreement, this 
Agreement shall terminate on the date of Executive's death. In this event, 
Executive's estate shall be entitled to receive all accrued but unpaid 
amounts of the Executive's Base Salary through the date of Executive's death, 
payable in accordance with the provisions of Section 3(a).  In addition, the 
Executive's eligible dependents shall be entitled to receive the health 
insurance benefits specified in Section 3(c)(1) above for a period of 12 
months (the "Company Continuation Period") following the effective date of 
termination and following such time period, such eligible decedents shall be 
entitled to all rights afforded to them under COBRA to purchase continuation 
coverage of such health insurance benefits for the maximum period permitted 
by law.  With respect to the preceding sentence, to the extent required by 
applicable law, the Executive's dependents shall be deemed to have elected to 
exercise their rights under COBRA as of the first day of the Company 
Continuation Period.  This Section 4(c) shall not limit the entitlement of 
Executive under any insurance or other benefits plan or policy that is 
maintained by Employer for Executive's benefit.

     (d)  TERMINATION FOLLOWING A CHANGE OF CONTROL.  If, within 24 months 
following a Change of Control, the Company terminates this Agreement and 
Executive's services other than for Cause or Executive terminates this 
Agreement with Good Reason, in either case by giving 30 days' prior written 
notice, Executive shall be entitled to receive the following benefits and 
payments:

                                       -6-
<PAGE>

          (i)  all accrued but unpaid amounts of the Base Salary through the
effective date of termination, payable in accordance with the provisions of
Section 3(a); 

          (ii) a pro rata portion of any Performance Bonus otherwise payable to
Executive for the calendar year in which such termination occurs up to the
effective date of such termination and, to the extent not previously paid, any
Performance Bonus for any calendar year prior to the calendar year in which such
termination occurs;

          (iii)     a termination distribution in an amount equal to the sum of
(A) Executive's then Base Salary and (B) Executive's last annualized Performance
Bonus (if the termination takes place prior to receipt by Executive of any
Performance Bonus, the Performance Bonus shall be deemed to be 50% of
Executive's then annual Base Salary), payable within 30 days of the effective
date of termination; and 

          (iv) any vested benefits or amounts pursuant to Sections 3(c), 3(d),
3(e) and 3(f) through the effective date of termination, payable in accordance
with the provisions of any such plan(s).  In addition, the Executive and his
eligible dependents shall be entitled to receive (x) the health insurance
benefits specified in Section 3(c)(1) for a period of 24 months following the
effective date of termination (the "Company Continuation Period"), and following
such time period, the Executive shall be entitled to all rights afforded to him
under COBRA to purchase continuation coverage of such health insurance benefits
for himself and his dependents for the maximum period permitted by law and (y)
the life insurance benefits specified in Section 3(f) for a period of 24 months
following the effective date of termination.  With respect to clause (x) of the
preceding sentence, to the extent required by applicable law, Executive shall be
deemed to have elected to exercise his rights under COBRA as of the first day of
the Company Continuation Period.

          (v)  Executive shall be fully vested in all amounts accrued or
accumulated on behalf of Executive under any nonqualified retirement plan
established or maintained by the Company, and the Company will promptly pay or
distribute all such amounts to Executive in accordance with the terms of such
plan as in effect on the date of this Agreement (or as of Executive's employment
termination, if more favorable to Executive).  If Executive is not fully vested
in his accounts or benefits under the Company's qualified retirement plan at his
employment termination pursuant to this Section, the Company will make a cash
payment to Executive, within 30 days of Executive's employment termination,
equal to the amount of such account or benefit that is forfeited.

          (vi) All stock awards or grants under the Horizon Group Properties,
Inc. 1998 Long-Term Stock Incentive Plan shall be fully vested and exercisable
as of Executive's employment termination.

     For purposes of this Agreement, a "Change of Control" shall be deemed to
have occurred if (1) any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended), other than a trustee
or other fiduciary holding securities under an employee benefit plan of
Employer, a corporation owned directly or indirectly by the stockholders of
Employer 

                                       -7-
<PAGE>

in substantially the same proportions as their ownership of stock of 
Employer, Executive or Michael W. Reschke, or any of their respective 
affiliates, becomes the "beneficial owner" (as defined in Rule 13d-3 under 
said Act), directly or indirectly, of securities of Employer representing 50% 
or more of the total voting power represented by Employer's then outstanding 
securities that vote generally in the election of directors (referred to 
herein as "Voting Securities"); (2) during any period of two consecutive 
years, individuals who at the beginning of such period constitute the Board 
and any new directors whose election by the Board or nomination for election 
by Employer's stockholders was approved by a vote of at least two-thirds of 
the directors then still in office who either were directors at the beginning 
of the period or whose election or nomination for election was previously so 
approved, cease for any reason to constitute a majority of the Board; (3) the 
stockholders of Employer approve a merger or consolidation of Employer with 
any other corporation, other than a merger or consolidation that would result 
in the Voting Securities of Employer outstanding immediately prior thereto 
continuing to represent (either by remaining outstanding or by being 
converted into Voting Securities of the surviving entity) at least 50% of the 
total voting power represented by the Voting Securities of Employer or such 
surviving entity outstanding immediately after such merger or consolidation; 
(4) the stockholders of Employer approve a plan of complete liquidation of 
Employer or an agreement for the sale or disposition by Employer of (in one 
transaction or a series of transactions) all or substantially all of 
Employer's assets. 

     5.   COVENANTS OF EXECUTIVE.

     (a)  NO CONFLICTS.  Executive represents and warrants that he is not
personally subject to any agreement, order or decree that restricts his
acceptance of this Agreement and performance of his duties with Employer
hereunder.

     (b)   NON-COMPETITION. In return for the performance of the duties 
described in Section 1, during the Employment Term and for a period of two 
years thereafter in the event of the termination of this Agreement pursuant 
to the provisions of Section 4(b)(ii) or one year thereafter in the event of 
termination of this Agreement pursuant to the provisions of Sections 4(a)(i), 
4(a)(ii), 4(a)(iii) or 4(b)(i), (the "Restrictive Period"), Executive shall 
not, directly or indirectly, in any capacity whatsoever, either on his own 
behalf or on behalf of any other person or entity with whom he may be 
employed or associated, own any interest in, participate or engage in the 
day-to-day supervision, management, development, marketing or operation of 
any factory outlet centers or such other business as Employer may be engaged 
in as of the date of the applicable Section 4 termination event (the 
"Business") which is competitive with any of Employer's centers.  For 
purposes hereof, a center will be deemed competitive with one of Employer's 
centers if such center is located within five miles of a center owned, 
operated or managed by Employer or within five miles of a center which 
Employer is developing or with respect to which Employer has signed a letter 
of intent or term sheet or binding contract for the acquisition, development 
or management thereof dated on or prior to the date of such termination.

          Furthermore, for a period of two years after any applicable Section 4
termination event, Executive shall not, directly or indirectly, solicit, attempt
to hire or hire any employee of Employer. Notwithstanding the foregoing, nothing
herein shall prohibit Executive from owning 5% 

                                       -8-
<PAGE>

or less of any securities of a competitor engaged in the same Business if 
such securities are listed on a nationally recognized securities exchange or 
traded over-the-counter on the National Association of Securities Dealers 
Automated Quotation System or otherwise.

     (c)  NONDISCLOSURE.  During the Restrictive Period and in the 
Restrictive Geographic Area, Executive shall not disclose or use, except in 
the pursuit of the Business for or on behalf of the Group, any Trade Secret 
(as hereinafter defined) of the Group, whether such Trade Secret is in 
Executive's memory or embodied in writing or other physical form.  For 
purposes of this Section 5(c), "Trade Secret" means any information that 
derives independent economic value, actual or potential, with respect to 
Employer from not being generally known to, and not being readily 
ascertainable by proper means by, other persons who can obtain economic value 
from its disclosure or use and is the subject of efforts to maintain its 
secrecy that are reasonable under the circumstances, including, but not 
limited to, trade secrets, customer lists, sales records and other 
proprietary commercial information.  Said term, however, shall not include 
general "know-how" information acquired by Executive during the course of his 
service which could have been obtained by him from public sources without the 
expenditure of significant time, effort and expense that does not relate to 
Employer.

     (d)  RETURN OF DOCUMENTS.  Upon termination of his services with 
Employer, Executive shall return all originals and copies of books, records, 
documents, customer lists, sales materials, tapes, keys, credit cards and 
other tangible property of Employer within Executive's possession or under 
his control.

     (e)  EQUITABLE RELIEF.  In the event of any breach by Executive of any 
of the covenants contained in this Section 5, it is specifically understood 
and agreed that Company shall be entitled, in addition to any other remedy 
that it may have, to equitable relief by way of injunction, an accounting or 
otherwise and to notify any employer or prospective employer of Executive as 
to the terms and conditions hereof.

     (f)  ACKNOWLEDGMENT.  Executive acknowledges that he will be directly 
and materially involved as a senior executive in all important policy and 
operational decisions of Company. Executive further acknowledges that the 
scope of the foregoing restrictions has been specifically bargained between 
Company and Executive, each being fully informed of all relevant facts.  
Accordingly, Executive acknowledges that the foregoing restrictions of 
Section 5 are fair and reasonable, are minimally necessary to protect 
Employer, its other stockholders and the public from the unfair competition 
of Executive who, as a result of his performance of services on behalf of 
Employer, will have had unlimited access to the most confidential and 
important information of Employer, its business and future plans. Executive 
further acknowledges that no unreasonable harm or injury will be suffered by 
him from enforcement of the covenants contained herein and that he will be 
able to earn a reasonable livelihood following termination of his services 
notwithstanding enforcement of the covenants contained herein.

     (g)  INDEMNIFICATION.  Subject to the provisions of this Agreement, 
Executive shall indemnify Employer for any and all consequential damages, 
costs and expenses (including legal 

                                       -9-
<PAGE>

fees) resulting from any of his acts or omissions that constitute bad faith, 
willful or intentional conduct that cause harm to Employer's business or 
reputation. Executive also shall indemnify Employer for any and all 
consequential damages, costs and expenses resulting from his acts of omission 
constituting reckless disregard of his duties to Employer following notice 
thereof by either Prime or the Operating Partnership after either becomes 
aware of such conduct and Executive's failure to so cure within 30 days.

     6.   GROSS UP PAYMENTS.  Anything in this Agreement to the contrary 
notwithstanding, in the event that any payment by or on behalf of Employer to 
or for the benefit of Executive (whether paid or payable or distributed or 
distributable pursuant to the terms of this Agreement or otherwise, but 
determined without regard to any additional payments required under this 
section) (the "Payments") is determined to be an "excess parachute payment" 
pursuant to Code Section 280G or any successor or substitute provision of the 
Code, with the effect that Executive is liable for the payment of the excise 
tax described in Code Section 4999 or any successor or substitute provision 
of the Code, or any interest or penalties are incurred by Executive with 
respect to such Payments (such excise tax, together with any such interest 
and penalties, are hereinafter collectively referred to as the "Excise Tax"), 
then Executive shall be entitled to receive an additional payment (the 
"Gross-Up Payment") in an amount such that after payment by Executive of all 
taxes imposed upon the Gross-Up Payment, including, without limitation, 
federal, state, local or other income taxes, FICA taxes, and additional 
Excise Tax (and any interest and penalties imposed with respect to such 
taxes), Executive retains a portion of the Gross-Up Payment equal to the 
Excise Tax imposed upon the Payments.

     (a)  DETERMINATION OF GROSS-UP.  Subject to the provisions of Section 
6(b), all determinations required to be made under this Section, including 
whether and when a Gross-Up Payment is required and the amount of such 
Gross-Up Payment and the assumptions to be utilized in arriving at such 
determination, shall be made by the public accounting firm that serves as 
Employer's auditors (the "Accounting Firm"), which shall provide detailed 
supporting calculations both to Employer and Executive within 15 business 
days of the receipt of notice from Employer or Executive that there have been 
Payments, or such earlier time as is requested by Employer.  In the event 
that the Accounting Firm is serving as accountant or auditor for the 
individual, entity or group effecting the Change of Control, Executive shall 
designate another nationally recognized accounting firm to make the 
determinations required hereunder (which accounting firm shall then be 
referred to as the Accounting Firm hereunder).  All fees and expenses of the 
Accounting Firm shall be borne solely by Employer.  Any Gross-Up Payment, as 
determined pursuant to this Section, shall be paid by Employer to Executive 
within five days after the receipt by Employer and Executive of the 
Accounting firm's determination.  If the Accounting Firm determines that no 
Excise Tax is payable by Executive, it shall furnish Executive with a written 
opinion that failure to report the Excise Tax on Executive's applicable 
federal income tax return would not result in the imposition of a negligence 
or similar penalty. Any determination by the Accounting Firm shall be binding 
upon Employer and Executive, except as provided in Section 6(b).

     (b)  IRS CLAIMS.  As a result of the uncertainty in the application of
Section 4999 of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that 

                                       -10-
<PAGE>

the Internal Revenue Service or other agency will claim that a greater Excise 
Tax is due, and thus a greater amount of Gross-Up Payment should have been 
made by Employer than that determined pursuant to paragraph (a) above (an 
"Underpayment").  In the event that Executive is required to make a payment 
of any such Excise Tax, the Accounting Firm shall determine the amount of the 
additional Gross-Up Payment due to Executive based on the Underpayment, and 
such additional Gross-Up Payment shall be promptly paid by Employer to or for 
the benefit of Executive. Executive shall notify Employer in writing of any 
claim by the Internal Revenue Service or other agency that, if successful, 
would require the payment by Employer of the Gross-Up Payment or an 
Underpayment.

     7.   PRIOR AGREEMENT.  This Agreement supersedes and is in lieu of any 
and all other employment arrangements between Executive and Employer, and any 
and all such employment or service agreements and arrangements are hereby 
terminated and deemed of no further force or effect.

     8.   ASSIGNMENT.  Neither this Agreement nor any rights or duties of 
Executive hereunder shall be assignable by Executive and any such purported 
assignment by him shall be void. Employer may assign all or any of its rights 
hereunder provided that substantially all of the assets of Employer are also 
transferred to the same party.

     9.   SUCCESSORS.  This Agreement shall inure to the benefit of and be 
enforceable by Executive's personal and legal representatives, executors, 
administrators, successors, heirs, distributees, devisees and legatees and 
Employer's successors and assigns.  If Executive should die while any amounts 
are still payable to Executive hereunder, all such amounts, unless otherwise 
provided herein, shall be paid in accordance with the terms of this Agreement 
to Executive's devisee, legatee or other designee or, if there be no such 
designee, to Executive's estate.  Employer will require any successor or 
assign (whether direct or indirect, by purchase, merger, consolidation or 
otherwise) to all or substantially all the business and/or assets of 
Employer, as the case may be, by agreement in form and substance reasonably 
satisfactory to Executive, expressly, absolutely and unconditionally to 
assume and agree to perform this Agreement in the same manner and to the same 
extent that Employer would be required to perform it if no such succession or 
assignment had taken place.  Any failure of Employer to obtain such agreement 
prior to the effectiveness of any such succession or assignment shall be a 
material breach of this Agreement.

     10.  NOTICES. Any notice required or permitted to be given under this 
Agreement shall be sufficient if in writing and if delivered in person or 
sent by any national overnight delivery service or by certified mail to the 
following addresses (or to any other address that any party may designate by 
notice to the other parties hereto):

     (a)  if to Executive, to:

     (b)  if to Employer, to:

     11.  AMENDMENT.  This Agreement may not be changed, modified or amended 
except in writing signed by all of the parties hereto.

     12.  WAIVER OF BREACH.  The waiver by any of the parties hereto of the 
breach of any provision of this Agreement shall not operate or be construed 
as a waiver of any subsequent breach by any part.

     13.  SEVERABILITY.  Employer and Executive each expressly agree and 
contract that it is not the intention of any of the parties hereto to violate 
any public policy, statutory or common law, and that if any sentence, 
paragraph, clause or combination of the same of this agreement is in 
violation of the law of any state where applicable, such sentence, paragraph, 
clause or combination of the same shall be void in the jurisdictions where it 
is unlawful, and the remainder of such paragraph and this Agreement shall 
remain binding on the panics to make the covenants of this Agreement binding 
only to the extent that it may be lawfully done under existing applicable 
laws.  In the event that any part of any covenant of this Agreement is 
determined by a court of competent jurisdiction to be overly broad thereby 
making the covenant unenforceable, the parties hereto agree, and it is their 
desire that such court shall substitute a judicially enforceable limitation 
in its place, and that as so modified the covenant shall be binding upon the 
parties as if originally set forth herein.

     14.  OPPORTUNITY TO EMPLOY COUNSEL.  Executive acknowledges receipt of a 
copy of this Agreement prior to his execution of this Agreement with Employer 
and also acknowledges that he has had ample time and opportunity to employ 
counsel of his choice to provide advice concerning the terms and conditions 
of this Agreement.

     15.  LEGAL FEES.  If Employer materially breaches any of its obligations 
to Executive under this Agreement and Executive brings any action, claim, 
demand, suit or proceeding against Employer to enforce his rights under this 
Agreement, Employer agrees that it will pay all reasonable legal fees and 
related legal costs (collectively "Legal Fees") incurred by Executive no 
later than 30 days following a judgment by a court of competent jurisdiction 
that Employer materially breached its obligations to Executive under this 
Agreement; provided, however, that if it is determined by a final judgment or 
other final adjudication by a court of competent jurisdiction that Employer 
did not materially breach any of its obligations to Executive under this 
Agreement, Executive will pay to Company within 30 days from such final 
judgment or adjudication the aggregate amount of legal fees and expenses 
incurred by Company with respect to such action and the amount of any Legal 
Fees that were previously paid to Executive by Employer pursuant to this 
Section 15.  Employer acknowledges the indemnification obligations of Prime 
to Executive and the other officers of Prime as set forth in its By-laws, as 
they may be amended from time to time.

                                       -12-

     16.  GOVERNING LAW. This Agreement shall be governed by, and construed, 
interpreted and enforced in accordance with the laws of the State of 
Maryland, exclusive of the conflict of laws provisions of the State of 
Maryland.

     17.  NOTICE OF FUTURE EMPLOYMENT.  Executive agrees that during the 24 
consecutive months immediately following the termination of this Agreement, 
Executive will within 14 days of each instance of new employment notify 
Employer in writing of the identity of his new employer and the job title 
associated with such employment.

     18.  BINDING EFFECT.  This Agreement shall be binding and legally 
enforceable against the parties hereto and their respective heirs, personal 
representatives, successors and assigns, as the case may be.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as 
of the date first written above.

                                   EMPLOYER:

Exhibit 10.10--Form of Working Capital Agreement by and between the Company 
               and Prime Retail, Inc.

                           WORKING CAPITAL AGREEMENT

     This Working Capital Agreement (the "Agreement") is entered into this 
15th day of June, 1998 by and between Prime Retail, Inc., a Maryland 
corporation ("Prime"), Prime Retail, L.P., a Delaware limited partnership 
("Prime L.P."), Horizon Group Properties, Inc., a Maryland corporation 
("HGP") and Horizon Group Properties, L.P., a Delaware limited partnership 
("HGP LP").

     WHEREAS, the transactions contemplated by that certain Amended and 
Restated Agreement of Merger dated as of February 1, 1998 (the "Merger 
Agreement") by and among Prime Retail, Inc., a Maryland corporation, Prime 
Retail, L.P., a Delaware limited partnership, Horizon Group, Inc. a Michigan 
corporation ("Horizon"), Sky Merger Corp., a Maryland corporation ("Sky 
Merger"), HGP, HGP LP and Horizon/Glen Outlet Centers Limited Partnership, a 
Delaware limited partnership ("Horizon Partnership"), will be consummated 
concurrently herewith;

     WHEREAS, the parties hereto wish to set forth their understanding with 
respect to various working capital and other matters in connection with the 
consummation of the transactions contemplated by the Merger Agreement and the 
Contribution Agreement (as defined in the Merger Agreement);

     NOW, THEREFORE, in consideration of good and valuable consideration, the 
receipt and sufficiency of which is hereby acknowledged, the parties hereto 
do hereby agree as follows:

     1.   WORKING CAPITAL FACILITY.  HGP LP has assumed from Horizon 
Partnership the obligations (the "Obligations") outstanding under or 
otherwise existing pursuant to or as set forth in that certain Business Loan 
Agreement dated as of August 1, 1996 (such agreement, as amended prior to the 
date hereof, and the documents executed in connection therewith, the "Loan 
Agreement") by and between Huntington National Bank and Horizon Partnership.  
The Loan Agreement matures on August 1, 1998.  HGP LP agrees to use its best 
efforts to refinance the Obligations as soon as possible following the 
Closing Date (as defined in the Merger Agreement); provided, however, any 
such refinancing shall be on terms and conditions reasonably acceptable to 
HGP LP.  In the event that such Obligations are not refinanced prior to the 
maturity date of the Loan Agreement, Prime and/or Prime LP agrees to enter 
into a two year term loan with HGP LP pursuant to which Prime and/or Prime LP 
will make available to HGP LP up to $4,000,000 in aggregate principal amount 
of indebtedness, upon terms and conditions substantially the same as those 
set forth in the Loan Agreement; provided that the interest rate shall be 10% 
per annum and the loan will be repayable prior to the maturity date thereof 
from the proceeds of (i) a sale of the outlet center in Algondones, New 
Mexico to the extent it is not used to repay another obligation on which 
Prime is contingently liable or (ii) a completion of an equity offering by 
HGP or HGP LP.

                                       -42-
<PAGE>

     2.   (a) WORKING CAPITAL ADJUSTMENT. The parties hereto understand and 
agree that a definitive amount of Working Capital (as hereinafter defined) is 
to be transferred to HGP, HGP LP and the other Horizon Entities (as 
hereinafter defined) in connection with the transfer of the properties listed 
on APPENDIX A hereto (the "Contributed Properties") and pursuant to the terms 
of the Merger Agreement and the Contribution Agreement.  Such working capital 
is in consideration of, among other things, the assumption by the Horizon 
Entities, of the known and unknown liabilities of the Contributed Properties 
in connection with the Formation Transactions (as hereinafter defined).  The 
parties hereto agree that the amount of Working Capital to be transferred, in 
the aggregate, to the Horizon Entities is $545,000 and that such amount shall 
be calculated and adjusted as set forth herein.  On the date hereof, Prime 
shall transfer cash to HGP and fund the reserves set forth on the Settlement 
Sheet attached hereto. The cash funding occurring on the date hereof is 
seventy-five percent (75%) of the amount of cash anticipated to be required 
to be made to HGP to comply with the working capital adjustment set forth 
herein.
     
          (b)  PREPARATION OF FINAL STATEMENTS.  As promptly as practicable 
after the date hereof and in any event not later than forty-five (45) days 
hereafter, HGP shall prepare and deliver to Prime an unaudited statement of 
assets and liabilities of each of the Contributed Properties as of the date 
hereof (the "Final Statements").  The delivery of the Final Statements shall 
not create any presumption as to the accuracy or completion  thereof.  The 
Final Statements shall be prepared in a manner consistent with Section 2(e) 
hereof and in accordance with GAAP.  Prime and its representatives and 
auditors shall be afforded the opportunity to review all underlying financial 
records and work papers pertaining to the preparation of the Final Statements 
and HGP shall permit Prime and its representatives full access to the books 
and records in HGP's possession relating to the Contributed Properties to 
permit Prime to review the Final Statements.  The aggregate Current Assets 
and Current Liabilities of the Contributed Properties as shown on the Final 
Statements prepared by HGP shall be final and binding for purposes of this 
Agreement unless Prime shall give written notice to HGP of disagreement with 
the values thereon involving more than $25,000 in the aggregate within thirty 
(30) business days following its receipt of the Final Statements, specifying 
in reasonable detail the nature and extent of such disagreement.  If Prime 
objects to the Final Statements and the parties are unable to resolve such 
dispute within fifteen (15) days after HGP's receipt of such notice, the 
dispute shall be submitted for determination to Ernst & Young.  Such public 
accounting firm shall review and decide the issues that are the subject of 
such dispute as specified in such notice as soon as possible after such 
submission and in any event within fifteen (15) days.  The decision of such 
accounting firm shall be set forth in writing and delivered to Prime and HGP. 
The decision of such accounting firm shall be final and binding Prime and 
HGP.  The fees and costs of such public accounting firm shall be borne 
equally by Prime and HGP.

                            ASSIGNMENT AND ASSUMPTION

     2.1  ASSIGNMENT AND ASSUMPTION OF ASSETS.

          (a)  Subject to Section 2.1(b) and to the satisfaction or waiver of
the conditions set forth in Article IV of this Agreement, immediately subsequent

<PAGE>

     2.3  TRANSFER AND ASSUMPTION DOCUMENTATION.  In furtherance of the
Assignment and Assumption, grant, conveyance, assignment, transfer and delivery
of the Purchased Assets and the assumption of the Assumed Liabilities set forth
in this Article III, at the Time of Assignment and Assumption or as promptly as
practicable thereafter (i) Indianapolis Partnership shall execute and deliver
such deeds, bills of sale, certificates of title, assignments of leases and
contracts and other instruments of sale, grant, conveyance, assignment, transfer

instruments of assumption as and to the extent necessary to evidence such
assumption.

     2.4  NONASSIGNABLE CONTRACTS.  Anything contained herein to the contrary
notwithstanding, this Agreement shall not constitute an agreement to assign any
lease, license agreement, contract, agreement, sale order, purchase order, open
bid or other commitment or asset if an assignment or attempted assignment of the
same without the consent of the other party or parties thereto would constitute
a breach thereof or in any way impair the rights after the Assignment and
Assumption of Prime Partnership Group or Indianapolis LLC thereunder.  Prime
Partnership Group shall, prior to the Time of Assignment and Assumption, use
reasonable best efforts (it being understood that such efforts shall not include
any requirement of Prime Partnership Group to expend money or offer or grant any
financial accommodation) as requested by Indianapolis LLC, and Indianapolis LLC
shall cooperate in all reasonable respects with Prime Partnership Group, to
obtain all consents and waivers and to resolve all impracticalities of
assignments or transfers necessary to convey to Indianapolis LLC the Purchased
Assets.  If any such consent is not obtained or if an attempted assignment would
be ineffective or would impair either group's rights under any such lease,
license agreement, contract, agreement, sale order, purchase order, open bid or
other commitment or asset so that Indianapolis LLC would not receive all such
rights, then Prime Partnership Group shall use reasonable best efforts (it being
understood that such efforts shall not include any requirement of Prime
Partnership Group to expend money or offer or grant any financial accommodation)
to provide or cause to be provided to Indianapolis LLC, to the extent permitted
by law, the benefits of any such lease, license agreement, contract, agreement,
sale order, purchase order, open bid or other commitment or asset.

     2.5  USE OF NAMES.

          (a)  Prior to the Assignment and Assumption, Prime Partnership Group
and Indianapolis LLC shall determine which of the names, trademarks, trade names
and other proprietary rights related to the Purchased Assets which Indianapolis
LLC shall have the sole and exclusive ownership of and right to use, as between
Indianapolis LLC, on the one hand, and Prime Partnership Group, on the other
hand, following the Time of Assignment and Assumption (the "Purchased
Proprietary Name Rights").  Following the Time of Assignment and Assumption,
Prime  Partnership Group shall have the sole and exclusive ownership of and
right to use, as between Indianapolis LLC on the one hand, and the Prime
Partnership Group on the other hand, all names, trade marks, trade names,
service marks and other proprietary rights owned or used by Prime  Partnership
Group immediately prior to the Time of Assignment and Assumption other than the
Purchased Proprietary Name Rights (the "Retained Proprietary Name Rights").


                                       4
<PAGE>

          (b)  Following the Assignment and Assumption (i)  Indianapolis LLC
shall take all action necessary to cease using, and change as promptly as
practicable (including by amending any charter documents), any corporate or
other names which are the same as or confusingly similar to any of the Retained
Proprietary Name Rights, and (ii) Prime shall, and shall cause its Subsidiaries
and other affiliates to, take all action necessary to cease using, and change as
promptly as practicable (including by amending any charter documents), any
corporate or other names which are the same as or confusingly similar to any of
the Purchased Proprietary Name Rights.  From and after the Closing Date,
Indianapolis LLC shall cease holding itself out as having an affiliation with
Prime Partnership Group.

                                  ARTICLE III

                               CERTAIN COVENANTS

     3.1  INDEMNITY AS BETWEEN INDIANAPOLIS LLC AND PRIME WITH RESPECT TO
ASSUMED AND RETAINED LIABILITIES.

          (a)  Effective upon the Assignment and Assumption, Indianapolis LLC
agrees to indemnify and hold Prime, its affiliates, successors and assigns and
the officers, directors, employees, agents, advisors and representatives of any
of them, harmless from and against any and all Indemnified Losses arising out of
or related to the Assumed Liabilities.  

          (b)  Effective upon the Assignment and Assumption, Prime agrees to
indemnify and hold Indianapolis LLC, its affiliates, successors and assigns and
the officers, directors, employees, agents, advisors and representatives of any
of them, harmless from and against any and all Indemnified Losses arising out of
or related to the Retained Liabilities.

     3.2  PROCEDURE FOR THIRD PARTY INDEMNIFICATION.  

          (a)  If a party entitled to be indemnified hereunder (an "Indemnified
Party") shall receive notice of the assertion by a person who is not a party to
this Agreement of any claim or of the commencement by any such person of any
Action (a "Third Party Claim") with respect to which a party hereto is obligated
to provide indemnification (an "Indemnifying Party"), such Indemnified Party
shall give such Indemnifying Party prompt notice thereof after becoming aware of
such Third Party Claim; provided that the failure of any Indemnified Party to
give notice as provided in this Section 3.2 shall not relieve the related
Indemnifying Party of its obligations under this Article III, except to the
extent that such Indemnifying Party is actually prejudiced by such failure to
give notice.  Such notice shall describe the Third Party Claim in reasonable
detail, and, if practicable, shall indicate the estimated amount of the
Indemnified Loss that has been or may be sustained by such Indemnified Party.

          (b)  An Indemnifying Party may elect to defend, at such Indemnifying
Party's own expense and by such Indemnifying Party's own counsel, any Third
Party Claim.  If an Indemnifying


                                       5
<PAGE>

Party elects to defend a Third Party Claim, it shall, within 30 days of notice 
of such Third Party Claim (or sooner, if the nature of such Third Party Claim 
so requires), notify the related Indemnified Party of its intent to do so and 
acknowledge its liability therefor, and such Indemnified Party shall cooperate 
in the defense of such Third Party Claim. After notice from an Indemnifying 
Party to an Indemnified Party of its election to assume the defense of a Third 
Party Claim, such Indemnifying Party shall not be liable to such Indemnified 
Party under this Article III for any legal or other expenses subsequently 
incurred by such Indemnified Party in connection with the defense thereof as 
long as the Indemnifying Party pursues such defense diligently and in good 
faith; provided that if, under applicable standards of professional conduct (as 
advised by counsel to the Indemnifying Party), a conflict on any significant 
issue between such Indemnified Party and such Indemnifying Party or between any 
two or more Indemnified Parties may exist in respect of such claim, then the 
Indemnifying Party shall pay the reasonable fees and expenses of one such 
additional counsel as may be required to be retained in light of such conflict. 
If an Indemnifying Party elects not to defend against a Third Party Claim, or 
fails to notify an Indemnified Party of its election as provided in this 
Section 3.2 within the time period specified, or fails to pursue the defense of 
a Third Party Claim diligently and in good faith, such Indemnified Party may 
defend, compromise and settle such Third Party Claim. Notwithstanding the 
foregoing, (i) neither an Indemnifying Party nor an Indemnified Party, as the 
party controlling the defense of a Third Party Claim, may compromise or settle 
any claim or consent to the entry of any judgment for other than monetary 
damages without the prior written consent of the other; provided that (upon 
reasonable notice thereof) consent to compromise or settlement or the entry of 
a judgment shall not be unreasonably withheld or delayed, and (ii) no 
Indemnifying Party shall consent to the entry of any judgment or enter into any 
compromise or settlement which does not include as an unconditional term 
thereof the giving by the claimant or plaintiff to such Indemnified Party and 
all other Indemnified Parties, as the case may be, subject to such Third Party 
Claim of a full and final release from all liability in respect of such claim 
or Action.

     3.3  ADJUSTMENT FOR INSURANCE AND TAXES.  The amount which either
Indianapolis LLC or Prime Partnership Group is required to pay to, for or on
behalf of the other pursuant to Sections 3.1 and 3.2, shall be adjusted
(including, without limitation, retroactively) (i) by any insurance proceeds
actually recovered by or on behalf of Indianapolis LLC, Prime Partnership Group
or the Indemnified Party, as the case may be, in reduction of the related
Indemnified Loss or Third Party Claim and (ii) reduced by the net difference
between  (A) the present value of the amount of any tax savings resulting from
any tax benefit to Indianapolis LLC, Prime Partnership Group or the Indemnified
Party, as the case may be, as a result of the Indemnified Loss or Third Party
Claim, and (B) the present value of the amount of any tax due with respect to
the receipt of the indemnification payment itself.  Amounts required to be paid,

may be, shall have received or shall have had paid on its behalf an Indemnified
Payment in respect of an Indemnified Loss or Third Party Claim and shall
subsequently receive insurance proceeds in respect of such Indemnified Loss or
Third Party Claim, or realize any net tax benefit (as computed in clause (ii)
above) as a result of such Indemnified Loss or Third Party Claim, then
Indianapolis LLC, Prime Partnership Group or the Indemnified Party, as the case
may be, shall pay to Indianapolis LLC,


                                       6

representing or warranting to such party in any way as to the assets, business
or Liabilities transferred, retained or assumed as contemplated hereby or as to
any consents or approvals required in connection with the consummation of the
transactions contemplated by this Agreement, it being agreed and understood that
each party shall take or keep all of its assets "AS IS", "WHERE IS" and that it
shall bear the economic and legal risk that conveyance of such assets shall
prove to be insufficient or that the title to any assets shall be other than

assume the liabilities and obligations with respect to, and continue to be
responsible for all liabilities and obligations whatsoever in connection with,
claims made by or on behalf of such persons in respect of salary, wages,
benefits, severance pay, salary continuation, COBRA continuation and similar
obligations relating to the continued employment, or the termination or alleged
termination of such persons' employment with the Indianapolis LLC by reason of
consummation of the transactions contemplated in this Agreement or the Merger
Agreement or otherwise and Indianapolis Partnership shall have no such
liability.

     3.6  INSURANCE.  The parties agree to cooperate with each other with
respect to the processing of any claims which are covered by any insurance
policy in existence prior to the Partnership Merger Effective Time.  Without
limiting the generality of the foregoing, Indianapolis Partnership or Prime
Partnership Group shall have the right to process and pursue any claim for
insurance (including negotiating with the company issuing the insurance policy)
in connection with any liability of Prime Partnership Group, regardless of
whether the insurance policy under which such claim is made is transferred to
Indianapolis LLC pursuant to Section 2.1(a), and Indianapolis LLC shall have the
right to process and pursue any claim for insurance (including negotiating with
the company issuing the insurance policy) in connection with any liability of
Indianapolis LLC or any of its Affiliates, regardless of whether the insurance
policy under which such claim is made is retained by Indianapolis Partnership
pursuant to Section 2.1(b).

respect to, the Retained Liabilities.

     2.3  TRANSFER AND ASSUMPTION DOCUMENTATION.  In furtherance of the
Assignment and Assumption, grant, conveyance, assignment, transfer and delivery
of the Purchased Assets and the


                                       3
<PAGE>

assumption of the Assumed Liabilities set forth in this Article II, at the Time 
of Assignment and Assumption or as promptly as practicable thereafter (i) 
Nebraska Partnership shall execute and deliver such deeds, bills of sale, 
certificates of title, assignments of leases and contracts and other 
instruments of sale, grant, conveyance, assignment, transfer and delivery 
necessary to evidence such sale, grant, conveyance, assignment, transfer and 
delivery and (ii)  Nebraska LLC shall execute and deliver such instruments of 
assumption as and to the extent necessary to evidence such assumption.

     2.4  NONASSIGNABLE CONTRACTS.  Anything contained herein to the contrary
notwithstanding, this Agreement shall not constitute an agreement to assign any
lease, license agreement, contract, agreement, sale order, purchase order, open
bid or other commitment or asset if an assignment or attempted assignment of the
same without the consent of the other party or parties thereto would constitute
a breach thereof or in any way impair the rights after the Assignment and
Assumption of Prime Partnership Group or Nebraska LLC thereunder.  Prime
Partnership Group shall, prior to the Time of Assignment and Assumption, use
reasonable best efforts (it being understood that such efforts shall not include
any requirement of Prime Partnership Group to expend money or offer or grant any
financial accommodation) as requested by Nebraska LLC, and Nebraska LLC shall
cooperate in all reasonable respects with Prime Partnership Group, to obtain all
consents and waivers and to resolve all impracticalities of assignments or
transfers necessary to convey to Nebraska LLC the Purchased Assets.  If any such
consent is not obtained or if an attempted assignment would be ineffective or
would impair either group's rights under any such lease, license agreement,
contract, agreement, sale order, purchase order, open bid or other commitment or
asset so that Nebraska LLC would not receive all such rights, then Prime
Partnership Group shall use reasonable best efforts (it being understood that
such efforts shall not include any requirement of Prime Partnership Group to
expend money or offer or grant any financial accommodation) to provide or cause
to be provided to Nebraska LLC, to the extent permitted by law, the benefits of
any such lease, license agreement, contract, agreement, sale order, purchase
order, open bid or other commitment or asset.

     2.5  USE OF NAMES.  

          (a)  Prior to the Assignment and Assumption, Prime Partnership Group
and Nebraska LLC shall determine which of the names, trademarks, trade names and
other proprietary rights related to the Purchased Assets which Nebraska LLC
shall have the sole and exclusive ownership of and right to use, as between
Nebraska LLC, on the one hand, and Prime Partnership Group, on the other hand,
following the Time of Assignment and Assumption (the "Purchased Proprietary Name
Rights").  Following the Time of Assignment and Assumption, Prime  Partnership
Group shall have the sole and exclusive ownership of and right to use, as
between Nebraska LLC on the one hand, and the Prime Partnership Group on the
other hand, all names, trade marks, trade names, service marks and other
proprietary rights owned or used by Prime Partnership Group immediately prior to
the Time of Assignment and Assumption other than the Purchased Proprietary Name
Rights (the "Retained Proprietary Name Rights").

          (b)  Following the Assignment and Assumption (i)  Nebraska LLC shall
take all action necessary to cease using, and change as promptly as practicable
(including by amending any


                                       4
<PAGE>

charter documents), any corporate or other names which are the same as or 
confusingly similar to any of the Retained Proprietary Name Rights, and (ii) 
Prime shall, and shall cause its Subsidiaries and other affiliates to, take all 
action necessary to cease using, and change as promptly as practicable 
(including by amending any charter documents), any corporate or other names 
which are the same as or confusingly similar to any of the Purchased 
Proprietary Name Rights.  From and after the Closing Date, Nebraska LLC shall 
cease holding itself out as having an affiliation with Prime Partnership Group.

                                  ARTICLE III

                               CERTAIN COVENANTS

     3.1  INDEMNITY AS BETWEEN NEBRASKA LLC AND PRIME WITH RESPECT TO ASSUMED
AND RETAINED LIABILITIES.

          (a)  Effective upon the Assignment and Assumption, Nebraska LLC agrees
to indemnify and hold Prime, its affiliates, successors and assigns and the
officers, directors, employees, agents, advisors and representatives of any of
them, harmless from and against any and all Indemnified Losses arising out of or
related to the Assumed Liabilities.  

          (b)  Effective upon the Assignment and Assumption, Prime agrees to
indemnify and hold Nebraska LLC, its affiliates, successors and assigns and the
officers, directors, employees, agents, advisors and representatives of any of
them, harmless from and against any and all Indemnified Losses arising out of or
related to the Retained Liabilities.

     3.2  PROCEDURE FOR THIRD PARTY INDEMNIFICATION.  

          (a)  If a party entitled to be indemnified hereunder (an "Indemnified
Party") shall receive notice of the assertion by a person who is not a party to
this Agreement of any claim or of the commencement by any such person of any
Action (a "Third Party Claim") with respect to which a party hereto is obligated
to provide indemnification (an "Indemnifying Party"), such Indemnified Party
shall give such Indemnifying Party prompt notice thereof after becoming aware of
such Third Party Claim; provided that the failure of any Indemnified Party to
give notice as provided in this Section 3.2 shall not relieve the related
Indemnifying Party of its obligations under this Article III, except to the
extent that such Indemnifying Party is actually prejudiced by such failure to
give notice.  Such notice shall describe the Third Party Claim in reasonable
detail, and, if practicable, shall indicate the estimated amount of the
Indemnified Loss that has been or may be sustained by such Indemnified Party.

          (b)  An Indemnifying Party may elect to defend, at such Indemnifying
Party's own expense and by such Indemnifying Party's own counsel, any Third
Party Claim.  If an Indemnifying Party elects to defend a Third Party Claim, it
shall, within 30 days of notice of such Third Party Claim (or sooner, if the
nature of such Third Party Claim so requires), notify the related Indemnified


                                       5
<PAGE>

Party of its intent to do so and acknowledge its liability therefor, and such
Indemnified Party shall cooperate in the defense of such Third Party Claim. 
After notice from an Indemnifying Party to an Indemnified Party of its election
to assume the defense of a Third Party Claim, such Indemnifying Party shall not
be liable to such Indemnified Party under this Article III for any legal or
other expenses subsequently incurred by such Indemnified Party in connection
with the defense thereof as long as the Indemnifying Party pursues such defense
diligently and in good faith; provided that if, under applicable standards of
professional conduct (as advised by counsel to the Indemnifying Party), a
conflict on any significant issue between such Indemnified Party and such
Indemnifying Party or between any two or more Indemnified Parties may exist in
respect of such claim, then the Indemnifying Party shall pay the reasonable fees
and expenses of one such additional counsel as may be required to be retained in
light of such conflict.  If an Indemnifying Party elects not to defend against a
Third Party Claim, or fails to notify an Indemnified Party of its election as
provided in this Section 3.2 within the time period specified, or fails to
pursue the defense of a Third Party Claim diligently and in good faith, such
Indemnified Party may defend, compromise and settle such Third Party Claim. 
Notwithstanding the foregoing, (i) neither an Indemnifying Party nor an
Indemnified Party, as the party controlling the defense of a Third Party Claim,
may compromise or settle any claim or consent to the entry of any judgment for
other than monetary damages without the prior written consent of the other;
provided that (upon reasonable notice thereof) consent to compromise or
settlement or the entry of a judgment shall not be unreasonably withheld or
delayed, and (ii) no Indemnifying Party shall consent to the entry of any
judgment or enter into any compromise or settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party and all other Indemnified Parties, as the case may be, subject
to such Third Party Claim of a full and final release from all liability in
respect of such claim or Action.

     3.3  ADJUSTMENT FOR INSURANCE AND TAXES.  The amount which either Nebraska
LLC or Prime Partnership Group is required to pay to, for or on behalf of the
other pursuant to Sections 3.1 and 3.2, shall be adjusted (including, without
limitation, retroactively) (i) by any insurance proceeds actually recovered by
or on behalf of Nebraska LLC, Prime Partnership Group or the Indemnified Party,
as the case may be, in reduction of the related Indemnified Loss or Third Party
Claim and (ii) reduced by the net difference between (A) the present value of
the amount of any tax savings resulting from any tax benefit to Nebraska LLC,
Prime Partnership Group or the Indemnified Party, as the case may be, as a
result of the Indemnified Loss or Third Party Claim, and (B) the present value
of the amount of any tax due with respect to the receipt of the indemnification
payment itself.  Amounts required to be paid, as so adjusted, are hereafter
sometimes called an "Indemnified Payment."  If Nebraska LLC, Prime Partnership
Group or the Indemnified Party, as the case may be, shall have received or shall
have had paid on its behalf an Indemnified Payment in respect of an Indemnified
Loss or Third Party Claim and shall subsequently receive insurance proceeds in
respect of such Indemnified Loss or Third Party Claim, or realize any net tax
benefit (as computed in clause (ii) above) as a result of such Indemnified Loss
or Third Party Claim, then Nebraska LLC, Prime Partnership Group or the
Indemnified Party, as the case may be, shall pay to Nebraska LLC, Prime
Partnership or the Indemnified Party, as the case may be, the amount of such
insurance proceeds or net tax benefit, or if less, the amount of the Indemnified
Payment.

except as otherwise specifically provided herein, no party nor any of its
Affiliates is, in this Agreement or any other agreement or document,
representing or warranting to such party in any way as to the assets, business
or Liabilities transferred, retained or assumed as contemplated hereby or as to
any consents or approvals required in connection with the consummation of the
transactions contemplated by this Agreement, it being agreed and understood that
each party shall take or keep all of its assets "AS IS", "WHERE IS" and that it
shall bear the economic and legal risk that conveyance of such assets shall
prove to be insufficient or that the title to any assets shall be other than
good and marketable and free from encumbrances.  ALL IMPLIED WARRANTIES,
INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE,
ARE HEREBY EXPRESSLY DISCLAIMED.

     3.5  TRANSFER OF EMPLOYEES.  Effective as of the Partnership Merger
Effective Time, Nebraska Partnership and Nebraska LLC shall cooperate to
transfer to the employ of Nebraska LLC, each person employed by Nebraska
Partnership, (such employees and other persons who become employees of Nebraska
LLC after the Partnership Merger Effective Time in accordance with this Section
3.5 shall be hereinafter referred to as the "Transferred Employees").  With
respect to the Transferred Employees, Nebraska LLC shall assume the liabilities
and obligations with respect to, and continue to be responsible for all
liabilities and obligations whatsoever in connection with, claims made by or on
behalf of such persons in respect of salary, wages, benefits, severance pay,
salary continuation, COBRA continuation and similar obligations relating to the
continued employment, or the termination or alleged termination of such persons'
employment with Nebraska LLC by reason of consummation of the transactions
contemplated in this Agreement or the Merger Agreement or otherwise and Nebraska
Partnership shall have no such liability.

     3.6  INSURANCE.  The parties agree to cooperate with each other with
respect to the processing of any claims which are covered by any insurance
policy in existence prior to the Partnership Merger Effective Time.  Without
limiting the generality of the foregoing, Nebraska Partnership or Prime
Partnership Group shall have the right to process and pursue any claim for
insurance (including negotiating with the company issuing the insurance policy)
in connection with any liability of Prime Partnership Group, regardless of
whether the insurance policy under which such claim is made is transferred to
Nebraska LLC pursuant to Section 2.1(a), and Nebraska LLC shall have the right
to process and pursue any claim for insurance (including negotiating with the
company issuing the insurance policy) in connection with any liability of
Nebraska LLC or any of its Affiliates, regardless of whether the insurance
policy under which such claim is made is retained by Nebraska Partnership
pursuant to Section 2.1(b).

     3.7  TRANSFER AND GAINS TAXES.  Nebraska LLC shall pay or cause to be paid
the Transfer and Gains Taxes imposed in connection with or as a result of the
Assignment and Assumption.

                   NONQUALIFIED STOCK OPTION AWARD AGREEMENT
                                     UNDER
      HORIZON  GROUP PROPERTIES, INC. 1998 LONG-TERM STOCK INCENTIVE PLAN


     This  NONQUALIFIED STOCK OPTION AWARD AGREEMENT (the "Agreement") dated
this 15TH day of June, 1998, between Horizon Group Properties, Inc. (the
"Company"), and          (the "Participant"), who is an officer, key employee or
director of the Company.  Any term capitalized but not defined in this Agreement
will have the meaning set forth in the Horizon Group Properties, Inc. 1998 
Long-Term Stock Incentive Plan (the "Plan").

1.   AWARD.  In accordance with the terms of the Plan, the Company hereby grants
     to the Participant a Nonqualified Stock Option to purchase all or any part
     of an aggregate of _____ Shares.  This Award constitutes a Nonqualified
     Stock Option and is not intended to be an Incentive Stock Option within the
     meaning of Section 422 of the Code.

2.   EXERCISE PRICE.  The Exercise Price will be $_______ per Share, which is no
     less than the Fair Market Value of a Share on the date of this Agreement.

3.   MEDIUM AND TIME OF PAYMENT.

     a.   The Exercise Price must be paid in United States dollars, in cash or
          by personal check payable to the order of the Company, at the time of
          purchase. 

     b.   Alternatively, the Exercise Price, or any part of it, may be paid
          with: (i) Shares owned by the Participant duly endorsed for transfer
          to the Company; (ii) Shares issuable to the Participant upon exercise
          of the Option; or (iii) any combination of cash, personal check and
          Shares meeting the requirements of clause (i) or (ii) above.

     c.   The Company will pay the amount of tax it is required to withhold on
          account of exercise of all or part of the Award with Shares otherwise
          issuable to the Participant upon exercise under the Award. 
          Notwithstanding the foregoing, if the Committee agrees, the
          Participant may satisfy the Company's withholding obligation by paying
          the amount of required withholding to the Company and, if he or she
          does so, the Company will not withhold Shares as described in the
          preceding sentence.  If the Award has been transferred pursuant to
          Section 6(b), the Participant must satisfy the Company's withholding
          requirement by paying the Company the amount it is required to
          withhold with:  (i) United States dollars in cash or by personal
          check; (ii) Shares owned by the Participant and duly endorsed for
          transfer to the Company; or (iii) any combination of cash, personal
          check, and Shares meeting the requirements of clause (ii) above. If
          part or all of the Award has been transferred pursuant to Section
          6(b), the withholding obligation may not be satisfied with Shares
          issuable upon exercise of the Award.

<PAGE>

     d.   Shares used to satisfy the Exercise Price and/or any minimum required
          withholding tax will be valued at their Fair Market Value as
          determined by the Committee as of the date of exercise. 

     e.   No Shares will be issued pursuant to the Award before the Exercise
          Price and, if applicable, the withholding obligation, have been paid
          in full.

4.   TERM, VESTING AND EXERCISE OF THE AWARD.

     a.   The Award will expire ten years from the date of this Agreement.

     b.   The Award will vest and become exercisable (i) in accordance with the
          vesting schedule set forth in paragraph (c) below or (ii) if earlier,
          the Participant's death or Disability.

     c.   The vesting schedule for this Award is as follows:

               ------------------------            --------------
               <S>                                 <C>
                        1st                              33%
                        2nd                              64%
                        3rd                             100%

</TABLE>

     d.   Notwithstanding any other provision of this Agreement, the Participant
          will forfeit his or her right to exercise the Award, whether or not it
          has already vested, if the Participant's employment with the Company
          is terminated for Cause.

     e.   After the Award has vested, and while it is exercisable, it may be
          exercised in whole or in part by written notice to the Company
          indicating the number of Shares being purchased.  The notice must be
          signed by the Participant and must be accompanied by full payment of
          the Exercise Price plus, if applicable, any required withholding tax. 
          Notwithstanding the foregoing, the Award may not be exercised for
          fewer than 100 Shares at any one time or, if fewer than 100 Shares
          remain, all the then-remaining Shares.  The Award must be exercised as
          to a whole number of Shares.

5.   TERMINATION OF EMPLOYMENT.  After termination of employment, the
     Participant's right to exercise the Award will be subject to the following
     rules.

     a.   DISABILITY OR DEATH.  If the Participant terminates employment through
          Disability or death, the Award will immediately vest and become
          exercisable.  The Participant (or in the case of his or her death, the
          Participant's estate) may exercise the Award within


                                      -2-
<PAGE>

          the 12-month period following the termination, or, if earlier, by the 
          date the Award would otherwise have expired.

     b.   OTHER TERMINATION.  If the Participant terminates employment for any
          reason other than Disability, death, or termination for Cause, the
          Participant (or, in the case of his or her subsequent death, the
          Participant's estate):  (i) may, within the 180-day period following
          the termination, exercise the Award to the extent that it was vested
          and exercisable on the date of the termination and (ii) will forfeit
          the Award to the extent that it was not vested and exercisable on the
          date of the termination.

     c.   CHANGE OF CONTROL.  Notwithstanding the provisions of paragraphs (a)
          and (b) above, if, within 24 months after a Change of Control, (i) the
          Participant's employment with the Company and all Affiliates is
          terminated for a reason other than Cause, or (ii) the Participant
          terminates his or her employment with the Company and all Affiliates
          for Good Reason, in either case by giving 30 days' prior written
          notice, the Award will immediately vest and become fully exercisable,
          and will remain exercisable until the date that is ten years after the
          date of this Agreement unless otherwise specifically prohibited under
          applicable law or by applicable rules and regulations of any
          governmental agency or national securities exchange.

          For purposes of this Agreement, a "Change of Control" shall be deemed
          to have occurred if (1) any "person" (as such term is used in Sections
          13(d) and 14(d) of the Securities Exchange Act of 1934, as amended),
          other than a trustee or other fiduciary holding securities under an
          employee benefit plan of the Company, a corporation owned directly or
          indirectly by the stockholders of the Company in substantially the
          same proportions as their ownership of stock of the Company, the
          Participant or Michael W. Reschke, or any of their respective
          affiliates, becomes the "beneficial owner" (as defined in Rule 13d-3
          under said Act), directly or indirectly, of securities of the Company
          representing 50% or more of the total voting power represented by the
          Company's then outstanding securities that vote generally in the
          election of directors (referred to herein as "Voting Securities"); (2)
          during any period of two consecutive years, individuals who at the
          beginning of such period constitute the Board of Directors of the 
          Company (the "Board") and any new directors whose election by the
          Board or nomination for election by the Company's stockholders was
          approved by a vote of at least two-thirds of the directors then still
          in office who either were directors at the beginning of the period or
          whose election or nomination for election was previously so approved,
          cease for any reason to constitute a majority of the Board; (3) the
          stockholders of the Company approve a merger or consolidation of the
          Company with any other corporation, other than a merger or
          consolidation that would result in the Voting Securities of the
          Company outstanding immediately prior thereto continuing to represent
          (either by remaining outstanding or by being converted into Voting
          Securities of the surviving entity) at least 50% of the total voting
          power represented by the Voting Securities of the Company or such
          surviving


                                      -3-
<PAGE>

          entity outstanding immediately after such merger or consolidation; 
          (4) the stockholders of the Company approve a plan of complete 
          liquidation of the Company or an agreement for the sale or disposition
          by the Company of (in one transaction or a series of transactions) all
          or substantially all of the Company's assets.

          For purposes of this Agreement, "Good Reason" shall have the meaning
          set forth in any unexpired employment or severance agreement between
          the Participant and the Company and/or an Affiliate.  In the absence
          of any such agreement, "Good Reason" shall exist if, without the
          Participant's written consent, (A) the Participant's title or scope of
          responsibilities and duties are materially diminished, or the Company
          fails to provide the Participant with adequate office facilities and
          support services to perform such responsibilities and duties, (B) the
          compensation payable to Executive for services to the  Company is
          materially reduced, or (C) the Company fails to continue in effect any
          cash or stock-based incentive or bonus plan, retirement plan, welfare
          benefit plan, or other benefit plan, program or arrangement, unless
          the aggregate value (as computed by an independent employee benefits
          consultant) of all such compensation, retirement and benefit plans,
          programs and arrangements provided to Executive is not materially less
          than their aggregate value as of the date of this Agreement (or as of
          the Change of Control, if greater).

6.   TRANSFERABILITY OF AWARD AND SHARES ACQUIRED UPON EXERCISE OF AWARD. 

     a.   The Participant may not sell, transfer, pledge, assign or otherwise
          alienate or hypothecate the Award, other than by will or the laws of
          descent and distribution.

     b.   Notwithstanding any other provision of this Agreement, the Participant
          may transfer any portion of this Award to:  (i) the Participant's
          spouse, children, step-children, grandchildren or step-grandchildren
          ("Immediate Family Members"); (ii) a trust or trusts for the exclusive
          benefit of Immediate Family Members; (iii) a partnership in which
          Immediate Family Members are the only partners; or (iv) an
          organization exempt from taxation under Section 501(c)(3) of the Code.
          Such a transfer is permitted only if there is no consideration for the
          transfer, or the transfer is to a partnership in which Immediate
          Family Members are the only partners and the Participant's sole
          consideration for the transfer is an interest in the partnership. 
          Such a transfer will become effective only if the Participant gives
          the Committee advance written notice of the transfer and complies with
          any conditions imposed by the Committee.  Following the transfer, the
          transferee will be subject to the same terms and conditions to which
          the Participant was subject immediately before the transfer, and the
          term "Participant" as used in this Agreement will be deemed to refer
          to the transferee, except for purposes of Sections 4(d) and 5, which
          will continue to apply with respect to the original Participant.  The
          transferee of an Award may not transfer the Award except as provided
          in paragraph (a).


                                      -4-
<PAGE>

     c.   During the Participant's lifetime, only the Participant (or a
          transferee pursuant to paragraph (b) above) or his or her guardian or
          legal representative may exercise the Award.  The Committee may, in
          its discretion, require a guardian or legal representative to supply
          it with the evidence the Committee reasonably deems necessary to
          establish the authority of the guardian or legal representative to
          exercise the Award on behalf of the Participant or transferee, as the
          case may be.

     d.   Except as limited by applicable federal or state securities laws, the
          requirements of any stock exchange or market upon which the Shares are
          listed or traded at any given time, and the provisions of Section 7,
          Shares acquired upon exercise of this Award will be freely
          transferable.

7.   SECURITIES LAW REQUIREMENTS.

     a.   If at any time the Committee determines that exercising the Award or
          issuing Shares would violate applicable securities laws, the Award
          will not be exercisable, and the Company will not be required to issue
          Shares.  The Committee may declare any provision of this Agreement or
          action of its own null and void if it determines the provision or
          action fails to comply with the short-swing trading rules.  As a
          condition to exercise, the Company may require the Participant to make
          written representations it deems necessary or desirable to comply with
          applicable securities laws.

     b.   No person who acquires Shares under this Agreement may sell the
          Shares, unless the offer and sale are made pursuant to  an effective
          registration statement under the Securities Act of 1933, as amended,
          which is current and includes the Shares to be sold, or an exemption
          from the registration requirements of that Act.

8.   NO OBLIGATION TO EXERCISE AWARD.  Neither the Participant nor his or her
     transferee is or will be obligated by the grant of the Award to exercise
     it.

9.   NO LIMITATION ON RIGHTS OF THE COMPANY.  The grant of the Award does not
     and will not in any way affect the right or power of the Company to make
     adjustments, reclassifications or changes in its capital or business
     structure, or to merge, consolidate, dissolve, liquidate, sell or transfer
     all or any part of its business or assets.

10.  PLAN AND AGREEMENT NOT A CONTRACT OF EMPLOYMENT.  Neither the Plan nor this
     Agreement is a contract of employment, and no terms of employment of the
     Participant will be affected in any way by the Plan, this Agreement or
     related instruments, except to the extent specifically expressed therein. 
     Neither the Plan nor this Agreement will be construed as conferring any
     legal rights of the Participant to continue to be employed, nor will it
     interfere with the Company's or any Affiliate's right to discharge the
     Participant or to deal with him or her regardless of the existence of the
     Plan, this Agreement or the Award.


                                      -5-
<PAGE>

11.  PARTICIPANT TO HAVE NO RIGHTS AS A STOCKHOLDER.  Before the date as of
     which he or she is recorded on the books of the Company as the holder of
     any Shares underlying the Award, the Participant will have no rights as a
     stockholder with respect to those Shares.

12.  NOTICE.  Any notice or other communication required or permitted under this
     Agreement must be in writing and must be delivered personally, sent by
     certified, registered or express mail, or sent by overnight courier, at the
     sender's expense.  Notice will be deemed given when delivered personally
     or, if mailed, three days after the date of deposit in the United States
     mail or, if sent by overnight courier, on the regular business day
     following the date sent.  Notice to the Company should be sent to Horizon
     Group Properties, Inc., 77 West Wacker Drive, Suite 3900, Chicago, Illinois
     60601, Attention: Corporate Secretary.  Notice to the Participant should be
     sent to the address set forth on the signature page below.

13.  SUCCESSORS.  All obligations of the Company under this Agreement will be
     binding on any successor to the Company, whether the existence of the
     successor results from a direct or indirect purchase of all or
     substantially all of the business and/or assets of the Company, or a
     merger, consolidation, or otherwise.

14   GOVERNING LAW.  This Agreement will be construed and enforced in accordance
     with, and governed by, the laws of the State of Maryland, determined
     without regard to its conflict of law rules.

15.  PLAN DOCUMENT CONTROLS.  The rights granted under this Agreement are in all
     respects subject to the provisions set forth in the Plan to the same extent
     and with the same effect as if set forth fully in this Agreement.  If the
     terms of this Agreement conflict with the terms of the Plan document, the
     Plan document will control.
