1 FIRST AMENDMENT TO PURCHASE AGREEMENT THIS FIRST AMENDMENT TO PURCHASE AGREEMENT (the "Amendment"), is made as of January 15, 1998, by and between ICG HOLDINGS, INC., a Colorado corporation ("Seller"), and TRINET ESSENTIAL FACILITIES X, INC., a Maryland corporation ("Buyer"), with reference to the following facts: A. Seller and Buyer entered into that certain Purchase Agreement, dated as of December 9, 1997 (the "Agreement"), with respect to the purchase and sale of the Property. Each capitalized term used in this Amendment, but not defined herein, shall have the meaning ascribed to it in the Agreement. B. Buyer and Seller have agreed that Buyer shall waive the condition precedent to the Closing that the Project has been Substantially Completed by the Closing Date, as set forth in Section 8.2(d) of the Agreement, as long as one hundred thirty percent (130%) of the Unpaid Project Costs shall not be disbursed to Seller at Closing, but is held in escrow to pay for the Unpaid Project Costs pursuant to the terms and provisions contained herein. C. Because the actual amount of Buyer's out-of-pocket costs in connection with the Purchase Agreement and the transactions contemplated thereby, the Lease and the Project, for which Seller is required to reimburse Buyer up to two hundred fifty thousand dollars ($250,000) pursuant to Section 9.3(b) of the Purchase Agreement, will not be determined by Closing, Buyer and Seller have agreed that two hundred eighteen thousand seven hundred ninety-seven and twenty-five hundredths dollars ($218,797.25) of the Purchase Price shall not be disbursed to Seller at Closing, but shall be held in escrow to satisfy Seller's obligation. D. Seller and Buyer desire to enter into this Amendment to modify the terms of the Agreement, all as set forth hereinbelow. NOW, THEREFORE, the parties agree as follows: 1. Holdback Escrow. The Agreement is hereby amended by adding new Sections 2.3 through 2.5 thereto, which read in their entirety as follows: "2.3 Funds for Unpaid Project Costs Held in Escrow. "(a) Escrow Account-A. Buyer and Seller acknowledge that there will be Unpaid Project Costs after the Closing Date.

If at any time Escrow Amount-A is insufficient to cover such costs incurred by Buyer to complete the Unfinished Work, Seller shall promptly pay Buyer for such costs upon demand by Buyer, as additional rent under the Lease. Seller's failure to pay such additional costs within ten (10) days after demand shall constitute an Event of Default under the Lease. "(c) Disbursements to Seller from Escrow Account-A.

Buyer and Seller shall instruct the Escrow Holder to make disbursements to Seller from Escrow Account-A amounts paid by Seller to complete the Punch-list Items pursuant to Section 2.3(c)(i). 3 "(d) Termination of Escrow Agreement. Buyer and Seller shall instruct the Escrow Holder that Escrow Account-A shall be closed and the Escrow Agreement shall terminate with respect to Escrow Account-A and any remaining amounts of Escrow Amount-A shall be paid to Seller upon the earlier to occur of the following: (i) all sums have been disbursed from Escrow Account-A in accordance with this section 2.3; or (ii) Buyer has received adequate evidence from Seller (in the form of an architect's certificate or such other evidence as Buyer may reasonably require) that the Punch-list Items have been completed in their entirety.

"(c) Termination of Escrow Agreement. Buyer and Seller shall instruct the Escrow Holder that Escrow Account-B shall be closed and the Escrow Agreement shall terminate with respect to Escrow Account-B and any remaining amounts of Escrow Amount-B shall be paid to Seller upon the earlier to occur of the following: (i) all sums have been disbursed from Escrow Account-B in accordance with this section 2.4; or (ii) Buyer and Seller have agreed in writing that Seller has fully satisfied its obligation to reimburse Seller for the Out-of-Pocket Costs. 4 "2.5 Arbitration.

"Except as otherwise required by law, the parties agree that the arbitration proceeding will be confidential; all conduct, statements, promises, offers, views and opinions, oral or written, made during the arbitration by any party or a party's agent, employee or attorney will remain confidential and, where appropriate, will be considered work product and privileged; and the existence and the results of the arbitration will be maintained by the parties and their respective agents, employees and attorneys as confidential at all times. "In the event that J.A.M.S./Endispute is no longer in existence at the time that arbitration is requested, the dispute shall be submitted to arbitration in accordance with the rules and procedures of the successor to J.A.M.S./Endispute or, if there is no such successor, the matter shall be submitted to an organization which consists of members similar to J.A.M.S./Endispute or its successor. 5 "The losing party shall bear all of its own and the prevailing party's costs and expenses incurred in connection with the arbitration, including the arbitrator's fees and costs." 2.
