5.        *  Covenants*. 

(a)    *      General Covenants.*Guarantor shall not without the prior writtenconsent of Buyer, permit or allow: 

(i)          admission of any Person(other than any direct or indirect subsidiary of Guarantor) as a holder of membership interests in Seller; provided, however, the foregoing shall not preclude the merger of Guarantor or its successor which does not effect a Change of Control;

(c)          *DYT AssetCovenants*. Except with respect to Liens in favor of Goldman Sachs Mortgage Company pursuant to the Goldman MRA and Liens disclosed on Schedule 8 to the Repurchase Agreement, Guarantor covenants and agrees with Lender that, until payment in fullof all Guaranteed Obligations, neither Guarantor nor any of Guarantor’s Subsidiaries shall create, incur, assume or permit to exist any Lien on any DYT Asset, nor assign or sell any income or revenues (including accounts receivable) or rightsin respect of any thereof to secure any of its Indebtedness (or any Indebtedness of such Subsidiary) or any guarantee, indemnity or other surety obligation in respect of Indebtedness of any other Person. 

6.          *Nature of Guaranty*. Guarantor’s liability under this Guaranty is a guaranty ofpayment and performance of the Guaranteed Obligations, and is not a guaranty of collection or collectibility. Guarantor’s liability under this Guaranty is not conditioned or contingent upon the genuineness, validity, regularity orenforceability of any of the Repurchase Documents. Guarantor’s liability under this Guaranty is a continuing, absolute, and unconditional obligation under any and all circumstances whatsoever (except as expressly stated, if at all, in thisGuaranty), without regard to the validity, regularity or enforceability of any of the Guaranteed Obligations. Guarantor acknowledges that Guarantor is fully obligated under this Guaranty even if Seller had no liability at the time of execution ofthe Repurchase Documents or later ceases to be liable under any Repurchase Document, whether pursuant to Insolvency Proceedings or otherwise. Guarantor shall not be entitled to claim, and irrevocably covenant not to raise or assert, any defense,counterclaim, set-off or deduction against the Guaranteed Obligations that would or might be available to Seller, other than actual payment and performance of all Guaranteed Obligations in full in accordance with their terms. Guarantor waives anyright to compel Buyer to proceed first against Seller or any Security before proceeding against Guarantor. Guarantor agrees that if any of the Guaranteed Obligations are or become void or unenforceable (because of 

 

4 

inadequate consideration, lack of capacity, Insolvency Proceedings, or for any other reason), then Guarantor’s liability under this Guaranty shallcontinue in full force with respect to all Guaranteed Obligations as if they were and continued to be legally enforceable, all in accordance with their terms before giving effect to the Insolvency Proceedings. Guarantor also recognizes andacknowledges that its liability under this Guaranty may be more extensive in amount and more burdensome than that of Seller. Guarantor waives any defense that might otherwise be available to Guarantor based on the proposition that a Guarantor’sliability cannot exceed the liability of the principal. Guarantor intends to be fully liable under the Guaranteed Obligations regardless of the scope of Seller’s liability thereunder. Without limiting the generality of the foregoing, if theGuaranteed Obligations are “nonrecourse” as to Seller or Seller’s liability for the Guaranteed Obligations is otherwise limited in some way, Guarantor nevertheless intends to be fully liable, to the full extent of Guarantor’sassets with respect to all the Guaranteed Obligations, even though Seller’s liability for the Guaranteed Obligations may be less limited in scope or less burdensome. Guarantor waives any defenses to this Guaranty arising or purportedly arisingfrom the manner in which Buyer disburses the Repurchase Transaction to Seller or otherwise, or any waiver of the terms of any Repurchase Document by Buyer or other failure of Buyer to require full compliance with the Repurchase Documents.Guarantor’s liability under this Guaranty shall continue until all sums due under the Repurchase Documents have been paid in full and all other performance required under the Repurchase Documents has been rendered in full, except as expresslyprovided otherwise (if at all) in this Guaranty. Guarantor’s liability under this Guaranty shall not be limited or affected in any way by any impairment or any diminution or loss of value of any Security whether caused by (a) hazardoussubstances, (b) Buyer’s failure to perfect a security interest in any Security, (c) any disability or other defense(s) of Seller, (d) any acts or omissions of Buyer, or (e) any breach by Seller of any representation orwarranty contained in any Repurchase Document. 

7.          *Waivers of Rights andDefenses*. Guarantor waives any right to require Buyer to (a) proceed against Seller, (b) proceed against or exhaust any Security, or (c) pursue any other right or remedy for Guarantor’s benefit. Guarantor agrees that Buyermay proceed against Guarantor with respect to the Guaranteed Obligations without taking any actions against Seller and without proceeding against or exhausting any Security. Guarantor agrees that Buyer may unqualifiedly exercise in its solediscretion (or may waive or release, intentionally or unintentionally) any or all rights and remedies available to it against Seller without impairing Buyer’s rights and remedies in enforcing this Guaranty, under which Guarantor’sliabilities shall remain independent and unconditional. Guarantor agrees and acknowledges that Buyer’s exercise (or waiver or release) of certain of such rights or remedies may affect or eliminate Guarantor’s right of subrogation orrecovery against Seller (if any) and that Guarantor may incur a partially or totally nonreimbursible liability in performing under this Guaranty. Guarantor has assumed the risk of any such loss of subrogation rights, even if caused by Buyer’sacts or omissions. If Buyer’s enforcement of rights and remedies, or the manner thereof, limits or precludes Guarantor from exercising any right of subrogation that might otherwise exist, then the foregoing shall not in any way limitBuyer’s rights to enforce this Guaranty. Without limiting the generality of any other waivers in this Guaranty, Guarantor expressly waives any statutory or other right that Guarantor might otherwise have to: (i) limit Guarantor’sliability after a nonjudicial foreclosure sale to the difference between the Guaranteed Obligations and the fair market value of the property or interests sold at such nonjudicial foreclosure sale or to any other extent, (ii) otherwise limitBuyer’s right to recover a deficiency judgment after any foreclosure sale, or (iii) require Buyer to exhaust its Security before Buyer may obtain a personal judgment for any deficiency. Any proceeds of a foreclosure or similar sale may beapplied first to any obligations of Seller that do not also constitute Guaranteed Obligations within the meaning of this Guaranty. Guarantor acknowledges and agrees that any nonrecourse or exculpation provided for in any Repurchase Document, or anyother provision of a Repurchase Document limiting Buyer’s recourse to specific Security or limiting Buyer’s right to enforce a deficiency judgment against Seller or any other Person, shall have absolutely no application to Guarantor’sliability under this Guaranty. To the extent that Buyer collects or receives any sums or payments from Seller, Buyer shall have the right, but not the 

 

5 

obligation, to apply such amounts first to that portion of Seller’s indebtedness and obligations to Buyer (if any) that is not covered by this Guaranty,regardless of the manner in which any such payments and/or amounts are characterized by the Person making payment. 

8.          *Additional Waivers*. Guarantor waives diligence and all demands, protests, presentments and notices of every kind or nature, including notices of protest, dishonor,nonpayment, acceptance of this Guaranty and the creation, renewal, extension, modification or accrual of any of the Guaranteed Obligations. Guarantor further waives the right to plead any and all statutes of limitations as a defense toGuarantor’s liability under this Guaranty or the enforcement of this Guaranty. No failure or delay on Buyer’s part in exercising any power, right or privilege under this Guaranty shall impair or waive any such power, right or privilege.

9.          *No Duty to Prove Loss*. To the extent that Guarantor at any timeincurs any liability under this Guaranty, Guarantor shall immediately pay Buyer (to be applied on account of the Guaranteed Obligations) the amount provided for in this Guaranty, without any requirement that Buyer demonstrate that Buyer hascurrently suffered any loss or that Buyer has otherwise exercised (to any degree) or exhausted any of Buyer’s rights or remedies with respect to Seller or any Security. 

10.        *Full Knowledge*. Guarantor acknowledges, represents, and warrants that it has had a full and adequate opportunity to review the RepurchaseDocuments, the transaction contemplated by the Repurchase Documents, and all underlying facts relating to such transaction. Guarantor represents and warrants that it fully understands: (a) the remedies Buyer may pursue against Seller and/orGuarantor in the event of a default under the Repurchase Documents, (b) the value (if any) and character of any Security, and (c) Seller’s financial condition and ability to perform under the Repurchase Documents. Guarantor agrees tokeep itself fully informed regarding all aspects of the foregoing and the performance of Seller’s obligations to Buyer. Buyer has no duty, whether now or in the future, to disclose to Guarantor any information pertaining to Seller, theRepurchase Transaction or any Security. If at any time provided for in the Repurchase Documents, then Guarantor agrees and acknowledges that an Insolvency Proceeding affecting Guarantor, or other actions or events relating to Guarantor (includingGuarantor’s change in financial position), as set forth in the Repurchase Documents, may be event(s) of default under the Repurchase Documents. 

11.        *Representations and Warranties*. Guarantor acknowledges, represents, and warrants as follows, and acknowledges that Buyer is relying upon the followingacknowledgments, representations, and warranties by Guarantor in making the Repurchase Transaction:

(b)          *No Conflict*. The execution, delivery, and performance of this Guaranty will not violate any provision of any law, regulation, judgment, order, decree, determination, oraward of any court, arbitrator or governmental authority, or of any mortgage, indenture, loan, or security agreement, lease, contract or other agreement, instrument or undertaking to which Guarantor is a party, in any material respect, or thatpurports to bind Guarantor or any of Guarantor’s property or assets. 

(c)          *No Third Party Consent Required*. No consent of any Person (including creditors or partners, members, stockholders, or other owners of Guarantor) is required in connectionwith Guarantor’s execution of this Guaranty or performance of Guarantor’s obligations under this Guaranty.

(d)          *Authority and Execution*. Guarantor is a corporation duly organized and validly existing under the laws of the State ofMaryland. Guarantor is qualified to do business, validly existing and is, to the extent determinable, in good standing, in all other jurisdictions in which the nature of the business conducted by it makes such qualification necessary, except wherefailure so to qualify would not have a material effect on its property, business or financial condition or prospects. Guarantor has full power, authority, and legal right to execute, deliver and perform its obligations under this Guaranty. Guarantorhas taken all necessary corporate and legal action to authorize this Guaranty, which has been duly executed and delivered and is a legal, valid, and binding obligation of Guarantor, enforceable in accordance with its terms. 

(e)          *No Representations by Buyer*. Guarantor delivers this Guaranty basedsolely upon its own independent investigation and based in no part upon any representation, statement, or assurance by Buyer. 

12.        *Reimbursement and Subrogation Rights*. Except to the extent that Buyer notifies Guarantor to the contrary in writing from time to time: 

(a)          *General Deferral of Reimbursement*. Guarantor waives any right to bereimbursed by Seller for any payment(s) made by Guarantor on account of the Guaranteed Obligations, unless and until all amounts under the Repurchase Documents have been paid in full and all periods within which such payments may be set aside orinvalidated have expired. Guarantor acknowledges that it has received adequate consideration for execution of this Guaranty by virtue of Buyer’s entering into the Repurchase Transaction (which benefits Guarantor, as an indirect beneficial ownerof Seller) and Guarantor does not require or expect, and is not entitled to, any other right of reimbursement against Seller as consideration for this Guaranty. 

(b)          *Deferral of Subrogation and Contribution*. Guarantor agrees it shall not assert any right of subrogation against Seller orBuyer, or right of subrogation against any Security unless and until in Buyer’s reasonable determination (a) all amounts due under the Repurchase Documents have been paid in full and all other performance required under the RepurchaseDocuments has been rendered in full to Buyer; and (b) all periods within which such payment and performance may be set aside or invalidated have expired (such deferral of Guarantor’s subrogation and contribution rights, the“Subrogation Deferral”).

(c)          *Effect of Invalidation*.

Guarantorshall not file any claim in any Insolvency Proceeding affecting Seller unless Guarantor simultaneously assigns and transfers such claim to Buyer, without consideration, pursuant to documentation fully satisfactory to Buyer. Guarantor shallautomatically be deemed to have assigned and transferred such claim to Buyer whether or not Guarantor executes documentation to such effect. By executing this Guaranty, Guarantor hereby authorizes Buyer (and grants Buyer a power of attorney coupledwith an interest, and hence irrevocable) to execute and file such assignment and transfer documentation on Guarantor’s behalf, which power of attorney may only be exercised by Buyer following the occurrence and continuance of an Event ofDefault. Buyer shall have the sole right to vote, receive distributions, and exercise all other rights with respect to any such claim, provided, however, that if and when the Guaranteed Obligations have been paid in full Buyer shall, subject toSection 14 below, relinquish all such rights, reassign such claim to Guarantor and release to Guarantor any further payments received on account of any such claim.
