This Agreement constitutes, and the other Transaction Documents to which HGPI and each Purchaser is a party when executed and delivered by HGPI and such Purchaser will constitute, the legal, valid and binding obligation of HGPI and each Purchaser, enforceable against HGPI and each Purchaser in accordance with their terms, subject to bankruptcy, insolvency and other similar laws affecting the rights and remedies of creditors generally and general principles of equity.

(c) The execution and delivery by HGPI and each Purchaser of, and the performance by HGPI and each Purchaser of its obligations under, the Transaction Documents to which it is a party and the consummation of the transactions contemplated hereby or thereby, do not and will not breach or conflict with, or give any Governmental Authority or other Person the right to challenge any of the transactions contemplated hereby or to exercise any remedy or obtain any relief under, any Applicable Law to which HGPI or either Purchaser may be subject.

4.3 Investment Intent. Each Purchaser is acquiring the Subject Partnership Interests for its own account and not with a view to its distribution within the meaning of Section 2(11) of the Securities Act of 1933, as amended. Each Purchaser is an “accredited investor” as such term is defined in Rule 501(a) under such act.

4.4 Evaluation. Each Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the acquisition of the Subject Partnership Interests, the Real Property and the Series C TIF Bonds and, having been furnished with or given access to, and having reviewed or been given an opportunity to review, all such information as it has considered necessary, has concluded that it is able to bear these risks. Except for the representations and warranties set forth in this Agreement, neither Purchaser has relied on any representations by any Seller, either Partnership or any of their respective members, managers, partners, directors, shareholders, trustees, officers, employees, agents, representatives, attorneys or affiliates in making the decision to acquire the Subject Partnership Interests and, indirectly, the Real Property and the Series C TIF Bonds. HGPI and each Purchaser acknowledges and agrees that, except as set forth in this Agreement, Sellers make no representations or warranties, express or implied, with respect to the assets, liabilities, business, operations, condition (financial or otherwise) or prospects of either Partnership, the Subject Partnership Interests, the Real Property or the Series C TIF Bonds, all of which are accepted by Purchasers on an “as is, where is” basis. In particular, and without limiting the generality of the foregoing, SELLERS DO NOT MAKE, AND HEREBY EXPRESSLY DISCLAIM, ANY WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE OF THE REAL PROPERTY OR OF ANY OTHER ASSET OF

EITHER PARTNERSHIP.

4.5 Brokers. No broker or finder has been employed or retained by HGPI or either Purchaser in connection with the transactions contemplated hereby, or, to HGPI’s or either Purchaser’s knowledge, is in any way connected with the transactions contemplated hereby.

5. COOPERATION, NOTICE AND OTHER COVENANTS.

5.1 Access and Investigation. Between the date of this Agreement and the Closing Date, Sellers shall (a) afford Purchasers full and free access to the properties, contracts, books and records, and other documents and data, of each Partnership, (b) furnish Purchasers with copies of all such contracts, books and records, and other existing documents and data as Purchasers may reasonably request that are in the possession of any Seller or either Partnership, and (c) furnish Purchasers with such additional financial, operating, and other data and information as Purchasers may reasonably request to the extent in the possession of any Seller or either Partnership. In that regard, Sellers shall make available to Purchasers complete and accurate copies of the Beal Mortgage Loan Documents, the Mortgages, any other documents in their possession relating to the Real Property, the environmental and physical condition of the Real Property and the Organizational Documents of the Partnerships. Purchasers shall, jointly and severally, indemnify, defend and hold harmless, Sellers and the Partnerships from and against any and all costs, losses, claims, expenses, liabilities or obligations resulting from physical injury, property damage, mechanics’ or materialmen’s liens or otherwise caused directly or indirectly by Purchasers’ review and inspection of the Real Property, the Other Assets or any of the above described information.

5.2 Cooperation and Commercially Reasonable Efforts. Subject to the terms and conditions of this Agreement, each Seller and Purchaser shall cooperate with one another in timely giving all notices, making all filings and obtaining all Consents of Lender and any other third parties, if any, necessary to consummate the transactions contemplated hereby, and the parties hereto agree to execute and deliver such other documents, certificates, agreements and other writings, and to use commercially reasonable efforts to take, or cause to be taken, such other actions and to do, or cause to be done, all things necessary or desirable in order to satisfy the conditions set forth in Section 6 hereof and to consummate the transactions contemplated hereby on or prior to the Outside Closing Date (or, if applicable, the Extended Outside Closing Date) or as soon thereafter as reasonably practicable.

5.3 Consent of Lender. Without limiting the generality of Section 5.2, each Seller and Purchaser acknowledges that the Consent of the Lender to the transactions contemplated hereby is required pursuant to the Beal Mortgage Loan Documents. Each Seller and Purchaser shall execute and deliver such documents, certificates, agreements and other writings, and use commercially reasonable efforts to take, or cause to be taken, such actions, and do, or cause to be done, all things necessary or desirable in order to satisfy the conditions precedent to the granting of the consent of the Lender. In the event the Consent of Lender is not received on or before July 15, 2003, or if Beal Bank requests, in exchange for its consent to the transactions contemplated by this Agreement, any substantial change in any of the Transaction Documents materially adverse to either Partnership, either Purchaser or any Seller, Purchasers or Sellers may terminate this Agreement by the delivery of written notice to the other, in which event, this Agreement, and the rights and obligations of the parties hereunder, shall immediately terminate, and this Agreement shall be of no further force or

effect.

5.4 Notice of Certain Events. Each Seller and Purchaser shall promptly notify the other of:

(i) any notice or other communication from any Person, alleging that the Consent of such Person is or may be required in connection with the consummation of any of the transactions contemplated hereby or otherwise asserting any objection to any of the transactions contemplated hereby;

(ii) any notice or other communication from any Governmental Authority in connection with the consummation of the transactions contemplated hereby;

(iii) any notice of any breach or inaccuracy of any of the representations and warranties made in this Agreement by any of the parties hereto; or

(iv) any actions, suits, claims, investigations or proceedings commenced or, to its knowledge, threatened against, relating to or otherwise affecting any party hereto that relate to the consummation of the transactions contemplated hereby.

5.5 Title Commitment and Survey.

(a) Concurrently with the execution of this Agreement, Sellers shall provide Purchasers with a title insurance policy commitment (“Title Commitment”) issued in June 2003 covering the Real Property. Sellers hereby represent and warrant that the Partnerships own fee simple title to the Real Property, subject to Permitted Exceptions.

(b) As promptly as practicable after the date hereof, Sellers shall endeavor to deliver to Purchasers a current survey of the Real Property (the “Survey”), provided, however, that such survey shall not be required to be delivered to Purchasers at or prior to the Closing if such survey has not been completed prior to the Closing. All costs of the Title Commitment and the Survey shall be borne by Sellers.

5.6 PGI Employees. On the Closing Date, HGPI shall offer to hire Messrs. Bohdan Hirniak and Philip Waters (together, the “PGI Employees”) as employees of HGPI having responsibilities similar to their respective current responsibilities with PGI with an annual base compensation not less than the respective annual base compensation currently paid to such employees by PGI. HGPI shall also provide the PGI Employees with such health, welfare and other employee benefit plans, programs and policies that are provided to similarly situated employees of HGPI, subject to any waiting period requirements not to exceed 60 days with respect to participation and coverage requirements applicable to the PGI Employees, and PGI shall be responsible for and shall pay all amounts under such health, welfare and other employee benefit plans for such waiting period not to exceed 60 days.

5.7 Development. For so long as the Prime Participation Interest is outstanding, Purchasers shall not, and shall cause the Partnerships not to, build structures on the Real Property for sale or rental.

5.8 Prime Freeman Road, L.L.C.. HDLP and Prime Freeman Road, L.L.C. (“PFR”) have

entered into an Agreement for Sale of Real Estate dated June 11, 2003, with the Kirk Corporation for the sale of a portion of the Real Property (the “HDLP/Kirk Parcel”) and certain real estate owned by PFR (the “PFR Parcel”). HDLP and PFR shall share the proceeds, net of all customary closing costs and expenses, of such sale based on the relative acreage of (a) the portion of the HDLP/Kirk Parcel that is zoned for residential use to (b) the PFR Parcel. Payments of any release prices to lenders who hold mortgages that encumber either parcel shall be paid from the net proceeds otherwise payable to the owner of the parcel being released. For example, if the residentially zoned portion of the HDLP/Kirk Parcel is 146.2 acres and the PFR parcel is 7.8 acres, HDLP’s share will be 94.94% and PFR’s share will be 5.06%. If the net proceeds are $18,000,000 and PFR’s mortgage is $850,000, PFR’s share will be $910,800 of which $850,000 will be used to obtain the release, leaving $60,800 of proceeds. HDLP’s share would be $17,089,200 from which the balance of the Beal Loan would be repaid.

8.12 Guarantee. HGPI hereby unconditionally and irrevocably guarantees to Sellers, without offset or deduction, (a) the prompt and full discharge when due by Purchasers and, with respect to Section 2.5, the Partnerships, of all of the Purchasers’ and the Partnerships’ payment obligations under this Agreement and the Prime Participation Interest in accordance with the terms hereof and thereof, the guarantee under this Section 8.12(a) constituting hereby a guarantee of payment and not of collection, and (b) the punctual and faithful performance by HGPI of each and every duty, agreement, covenant and other obligation of Purchasers and, with respect to Section 2.5, the Partnerships, under and in accordance with the terms of this Agreement and the Prime Participation Interest. HGPI also hereby agrees that, if either Purchaser or Partnership fails to perform and discharge promptly all such obligations and liabilities in accordance with such terms, HGPI will, forthwith, upon demand, perform and discharge the same. The obligations of the Purchasers and the Partnerships hereby guaranteed are hereinafter called the “Obligations”. The unconditional obligation of HGPI hereunder will not be affected, impaired or released by any extension, waiver or amendment. Without limiting the generality of the foregoing, HGPI specifically agrees that it shall not be necessary or required, and that it shall not be entitled to require, that Sellers file suit or proceed to obtain or assert a claim for personal judgment against either Purchaser or Partnership for the Obligations or make any effort at collection of the Obligations from either Purchaser or Partnership or foreclose against or seek to realize upon any security now or hereafter existing for the Obligations or file suit or proceed to obtain or assert a claim for personal judgment against any other party liable for the Obligations or make any effort at collection of the Obligations from any such other party or exercise or assert any other right or remedy to which any of them is or may be entitled in connection with the Obligations or any security or other guarantee therefor or assert or file any claim against the assets of either Purchaser or Partnership or other person liable for the Obligations, or any part thereof, before or as a condition of enforcing the liability of HGPI under this Section 8.12 or requiring payment of said Obligations by HGPI hereunder or under the Prime Participation Interest, or at any time thereafter.

8.13 Survival. The representations and warranties made in this Agreement or in any certificate or agreement delivered in connection herewith shall terminate on December 31, 2004; provided, however, that any claims of a breach of any such surviving representation or warranty made in good faith prior to December 31, 2004 shall survive such date to the extent of the facts alleged in such claim.

8.14 Knowledge. The parties acknowledge and agree that if (a) Mr. Gary J. Skoien has actual knowledge (regardless of whether or not Bohdan Hirniak or Philip Waters have actual knowledge) of any breach or inaccuracy by Sellers of, or of any facts or circumstances the existence or omission of which would constitute a breach or inaccuracy of, any representation or warranty of Sellers contained in this Agreement, and (b) neither Mr. Michael W. Reschke nor Mr. Mark Cynkar has actual knowledge of such breach or inaccuracy, or of such facts or circumstances the existence or

omission of which would constitute a breach or inaccuracy of, such representation or warranty, then Purchasers shall be deemed to have waived such breach or inaccuracy and neither Purchaser nor any of its successors, assigns or affiliates shall be entitled to sue for damages or to assert any failure of a condition or assert any other right or remedy for any losses arising from any matters relating to such breach, inaccuracy, fact or circumstance, notwithstanding anything to the contrary contained herein or in any certificate or agreement delivered pursuant hereto.

8.15 Buy-Sell Procedures.

(a) For a period of six (6) months (the “Exercise Period”) following the fifth (5^th) anniversary of the Closing Date, either Sellers or Purchasers (such electing party, the “Exercising Party”) may elect to present a notice to the other party (the “Recipient Party”) that the Exercising Party chooses to proceed under this Section 8.15. Concurrently with such notice, the Exercising Party shall deliver to the Recipient Party an offer (the “Offer”) setting forth a dollar purchase price attributable to one hundred percent (100%) of the assets (without regard to the Partnerships’ liabilities) of the Partnerships (the “Partnerships Value”) and agreeing to sell or purchase (as elected or deemed elected by the Recipient Party pursuant to clause (b) below) either the Purchasers’ interest in the Partnerships or the Prime Participation Interest, as applicable, at a price determined with reference to such Partnerships Value as described below.

(b) Upon receipt of an Offer pursuant to the preceding subparagraph (a) the Recipient Party shall then be obligated either (i) to purchase the interest of the Exercising Party in the Partnerships for cash or (ii) to sell to the Exercising Party the interest of the Recipient Party in the Partnerships for cash, in either case at a purchase price based upon the Partnerships Value established under subparagraph (a) and calculated in accordance with the second to last sentence of subparagraph (c) of this Section 8.15 (the “Buy/Sell Purchase Price”). The Recipient Party shall give written notice of its election under the preceding clause (i) or (ii) to the Exercising Party within sixty (60) days after receipt of the Offer. If the Recipient Party fails to give such notice of its election within sixty (60) days after receipt of the Offer, it shall be deemed on such 60^th day to have given notice of its election to sell its interests, and the Exercising Party shall be obligated to purchase the interest of the Recipient Party in accordance with this Section 8.15. Within ten (10) days after receipt of notice from the Recipient Party elects to sell (or seventy (70) days after delivery of the Offer to the Recipient Party if it fails to give notice of its election within sixty days after receipt of the Offer), the Exercising Party shall deposit with an escrow agent mutually acceptable to both parties, twenty percent (20%) of the Buy/Sell Purchase Price in the form of cash or a letter of credit issued by a reputable financial institution. If the Recipient Party elects to purchase, within ten (10) days after providing notice of its election to purchase, it shall deposit with an escrow agent mutually acceptable to both parties twenty percent (20%) of the Buy/Sell Purchase Price, in the form of cash or a letter of credit issued by a reputable financial institution.

(c) The closing of a purchase pursuant to this Section 8.15 shall be held at the principal office of the Partnerships on or before one hundred eighty (180) days after the giving (or deemed giving) of the written notice of the Recipient Party’s election under clause (i) or (ii) of the preceding subparagraph (b). At such closing, the selling party shall assign to the purchasing party, by such instruments of transfer as may reasonably be requested by the purchasing party, the interest in the Partnerships to be sold free and clear of all claims liens, security interests and encumbrances and, at the request of the purchasing party, in order to properly set forth the record title to the assets

of the Partnerships, shall convey and transfer to the purchasing party, with covenants of special warranty as to the selling party’s interest in the Partnerships, an undivided percentage interest in the assets of the Partnerships in the same percentage as the selling party’s percentage interest and execute all other documents that may be necessary to effectuate the purposes of this Section 8.15 and effectuate a smooth and efficient continuation of the affairs of the Partnerships. At the closing, the purchasing party shall pay the Buy/Sell Purchase Price for such interest in the Partnerships in cash or by cashier’s or certified check issued by a bank reasonably acceptable to the selling party. The purchase price to be paid by the purchasing party shall be equal to the sum, if any, which the selling party would receive if the assets of the Partnerships were sold for the Partnerships Value on the day prior to the date of the delivery of the Offer, the Partnerships dissolved and the proceeds of such hypothetical sale distributed to the Purchasers (if Sellers are the purchasing party) or to Sellers pursuant to the Prime Participation Interest (if Purchasers are the purchasing party) in accordance with this Agreement and the priorities set forth in the partnership agreement of each such Partnership. If Sellers are the purchasing party under this Section 8.15, then at the closing, all principal and accrued interest owing by the partnership to the Purchasers and their Affiliates as a result of loans made to the Partnerships shall be paid in full, and the Purchasers and all of their Affiliates shall be released from all guarantees granted and obligations assumed by the Purchasers or any of their respective Affiliates in connection with such Purchaser’s interests in the Partnerships or in connection with the activities of the Partnerships or in lieu of the release, shall receive indemnification for any amounts owed by such party pursuant to such guarantees or obligations; such indemnification shall be provided by a party with sufficient financial wherewithal reasonably satisfactory to the indemnified party.

(d) If either of the Exercising Party or Recipient Party is obligated pursuant to subparagraph (b) of this Section 8.15 to purchase the interest of the other in the Partnerships (including, if applicable, the Prime Participation Interest) and thereafter does not close the purchase of such interest pursuant hereto, then such party shall be deemed to be in default pursuant hereto and the other party, as its exclusive remedy in law and equity in respect of such default, shall be entitled to the Escrow Account as liquidated damages.
