(formerly HEALTH SYSTEMS ARCHITECTS, INC.) ("HSA"), a Delaware corporation and a wholly-owned subsidiary of HISCo. RECITALS A. The parties wish to provide for the merger (the "Merger") of Sub and HSA into HISCo, whereby it is contemplated, among other things, that all shares of common stock, $0.01 par value, of HISCo issued and outstanding ("HISCo Common Stock") immediately prior to the Effective Time of the Merger, as hereinafter defined, other than (1) HISCo Common Stock held by HMS and (2) Dissenting Shares, if any, as defined, will be converted into the right to receive $11.96 per share (the "Per Share Purchase Price") in cash, subject to adjustment as provided for in Section 2.3(e) of this Agreement. B. The parties hereto desire to set forth certain representations, warranties and covenants made by HMS and Sub to HISCo and HSA, and by HISCo and HSA to HMS and Sub, and the conditions precedent to the consummation of the Merger. C. The Boards of Directors of HMS, Sub, HISCo and HSA, respectively, have approved and adopted this Agreement and the Merger; NOW, THEREFORE, in consideration of the premises and of the mutual provisions, agreements and covenants herein contained, HMS, Sub, HISCo and HSA hereby agree as follows: ARTICLE 1. DEFINITIONS 1.1 Certain Definitions. The terms defined in this Section 1.1 shall, for all purposes of this Agreement, have the meanings herein specified, unless the context expressly or by necessary implication otherwise requires: (a) "Dissenting Shares" shall mean shares of HISCo Common Stock which shall be owned by stockholders who shall duly perfect appraisal rights in accordance with Section 262 of the Delaware General Corporation Law (the "GCL"). 7 (b) "Dissenting Stockholders" shall mean those stockholders of HISCo who are holders of Dissenting Shares and are entitled to appraisal rights. (c) "HISCo Founders Shares" shall mean the shares of HISCo Common Stock purchased in connection with the formation of HSA (then known as "Health Information Systems Corporation") for a cash purchase price of $0.01 per share, as set forth on Schedule 3.2 attached hereto. (d) "HISCo Stockholders" shall mean all holders of HISCo Common Stock immediately prior to the Effective Time of the Merger. (e) "HISCo Stockholders' Meeting" shall mean the meeting, and any adjournments thereof, of the holders of HISCo Common Stock called and convened for the purpose of their consideration of and voting upon the transactions contemplated by this Agreement and the Merger (the parties hereto agreeing that approval of this Agreement and the Merger may instead be obtained by means of written consents in accordance with Section 228(a) of the GCL). (f) "Material Adverse Effect" on any entity (or group of entities taken as a whole) shall mean an effect that is materially adverse to the consolidated financial condition, assets, liabilities, business or results of operations of such entity (or, if with respect thereto, of such group of entities taken as a whole). (g) "Material Agreements," as used in relation to HISCo and HSA, shall have the meaning ascribed to such term in Section 3.12. (h) "Subsidiary" means a corporation whose voting securities are owned directly or indirectly by a "parent" corporation in such amounts as are sufficient to elect at least a majority of the Board of Directors of the Subsidiary. (i) "Taxes" shall mean all taxes, charges, fees, levies or other assessments including, without limitation, income, gross receipts, excise, property, sales, withholding, social security, occupation, use, service, license, payroll, franchise, transfer and recording taxes, fees and charges, imposed by the United States, or any state, local or foreign government or subdivision or agency thereof whether computed on a separate, consolidated, unitary, combined or any other basis; and such term shall include any interest, fines, penalties or additional amounts attributable or imposed with respect to any taxes, charges, fees, levies or other assessments. 2 8 1.2 Other Definitions. In addition to the terms defined in Section 1.1, certain other terms are defined elsewhere in this Agreement; whenever such terms are used in this Agreement they shall have their respective defined meanings, unless the context expressly or by necessary implication otherwise requires. ARTICLE 2. THE MERGER 2.1 Effective Time of the Merger. Subject to the provisions of this Agreement, a Certificate of Merger, together with all other required certificates, shall be filed in accordance with the requirements of Section 251 of the GCL as soon as practicable on or after the Closing Date. The Merger shall become effective upon the filing of such certificate with the Secretary of State of the State of Delaware (the "Effective Time of the Merger"). 2.2 Effects of the Merger. At the Effective Time of the Merger: (a) the separate existence of Sub and HSA shall cease and Sub and HSA shall be merged with and into HISCo as the surviving corporation (the "Surviving Corporation"); (b) HISCo's Certificate of Incorporation, as amended by the Certificate of Merger, and By-laws shall be the Certificate of Incorporation and By-laws of the Surviving Corporation; and (c) the persons listed on Exhibit A shall be the directors and officers of the Surviving Corporation, and such officers shall continue to act as such and hold such offices in the Surviving Corporation, until their respective successors are duly elected and qualified. 2.3 Effect on HISCo Securities. As of the Effective Time of the Merger, by virtue of the Merger and without any action on the part of the holder of any shares of the issued and outstanding shares of HISCo Common Stock: (a) Cancellation of HISCo Common Stock Owned by HISCo. All shares of HISCo Common Stock that are owned directly or indirectly by HISCo or any Subsidiary of HISCo shall be cancelled, and no cash or other consideration shall be delivered in exchange therefor. (b) Conversion of HISCo Common Stock Owned by HMS. All shares of HISCo Common Stock, if any, that are owned directly or indirectly by HMS or any Subsidiary of HMS shall be converted into 3 9 shares of issued and outstanding common stock of the Surviving Corporation on the basis of 1,600 shares of HISCo Common Stock for each share of capital stock of the Surviving Corporation. (c) Conversion of HISCo Common Stock Owned by HISCo Stockholders Other Than HMS. Other than shares of HISCo Common Stock owned directly or indirectly by HMS or any Subsidiary of HMS to be converted pursuant to Section 2.3(a) and Dissenting Shares, each share of HISCo Common Stock issued and outstanding immediately prior to the Effective Time of the Merger shall be converted, without any action on the part of the holders thereof, into the right to receive the Per Share Purchase Price. (d) Adjustments of Price. If, after the date of this Agreement, the outstanding shares of HISCo Common Stock shall have been changed into a different number of shares or a different class by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or readjustment or a stock dividend thereon shall be declared with a record date within said period, then, in addition to all other rights and remedies that HMS and Sub may have by reason of such event, HMS and Sub, in their sole discretion, may elect that the Per Share Purchase Price shall be correspondingly adjusted. (e) Dissenters' Rights of HISCo Stockholders. Any Dissenting Shares shall not be converted into the right to receive the Per Share Purchase Price but shall be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to the GCL. HISCo shall give HMS prompt notice of any demand received by HISCo for the right to receive payment of the fair market value for the HISCo Common Stock, and HMS shall have the right to participate in all negotiations and proceedings with respect to such demand. HISCo agrees that, except with the prior written consent of HMS, or as required under the GCL, HISCo will not voluntarily make any payment with respect to, or settle or offer to settle, any such demand for appraisal. Each Dissenting Stockholder who, pursuant to Section 262 of the GCL, becomes entitled to payment of the value of shares of HISCo Common Stock shall receive payment therefor (but only after the value therefor shall have been agreed upon or finally determined pursuant to such provisions). In the event of the legal obligation, after the Effective Time of the Merger, to deliver the Per Share Purchase Price to any Dissenting Stockholder who shall have failed to make an effective demand for appraisal or shall have lost his status as a Dissenting Stockholder, HMS shall issue and deliver, upon surrender by such Dissenting Stockholder of his certificate or certificates representing shares of HISCo Common Stock, the aggregate Per Share Purchase Price to which such 4 10 Dissenting Stockholder is then entitled under this Section 2.3, and Section 262 of the GCL. 2.4 Conversion of Sub Capital Stock. Each share of Sub capital stock issued and outstanding immediately prior to the Effective Time of the Merger shall be converted, without any action on the part of the holder thereof, into one share of issued and outstanding capital stock of the Surviving Corporation. 2.5 Cancellation of HSA Capital Stock. Each share of HSA capital stock issued and outstanding immediately prior to the Effective Time of the Merger shall be cancelled, and no cash or other consideration shall be delivered in exchange therefor. 2.6 Payment of Per Share Purchase Price. (a) As soon as practicable after the Effective Time of the Merger, HMS shall mail to each holder (other than HMS or any Subsidiary of HMS) of record of a certificate or certificates representing then outstanding shares of HISCo Common Stock (the "Certificates"), a Letter of Transmittal or similar instrument for use in effecting the surrender of the Certificates in exchange for the Per Share Purchase Price pursuant to Section 2.3 hereunder. Upon surrender to HMS of a Certificate for cancellation after the Effective Time of the Merger, the holder of such Certificate shall be entitled to receive in exchange therefor the aggregate Per Share Purchase Price to which the holder of HISCo Common Stock is entitled pursuant to Section 2.3 of this Agreement and is represented by the Certificate so surrendered. The Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of HISCo Common Stock which is not registered in the transfer records of HISCo, the aggregate Per Share Purchase Price may be paid to a transferee if the Certificate representing the right to receive such aggregate Per Share Purchase Price is presented to HMS and accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.4, each Certificate shall be deemed at any time after the Effective Time of the Merger to represent the right to receive upon such surrender the aggregate Per Share Purchase Price as provided by Section 2.3 and the provisions of the GCL. (b) No Further Ownership Rights in HISCo Common Stock. Payment of the aggregate Per Share Purchase Price upon the surrender for exchange of shares of HISCo Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of 5 11 HISCo Common Stock. There shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of HISCo Common Stock which were outstanding immediately prior to the Effective Time of the Merger. If, after the Effective Time of the Merger, Certificates, with respect to shares of HISCo Common Stock owned by HISCo Stockholders other than HMS or any Subsidiary of HMS are presented to the Surviving Corporation for any reason, they shall be canceled and the aggregate Per Share Purchase Price or Per Option Purchase Price, as the case may be, shall be paid therefor as provided in this Article 2. ARTICLE 3. REPRESENTATIONS AND WARRANTIES OF HISCo and HSA Each of HISCo and HSA represents and warrants to HMS and Sub as of the date hereof and as of the Closing Date as follows: 3.1 Organization and Standing. Each of HISCo and HSA is a corporation duly organized, validly existing, and in good standing under the laws of the jurisdiction of its incorporation, and has the full power and authority (corporate and otherwise) to carry on its business in the places and as it is now being conducted and to own and lease the properties and assets which it now owns or leases. 3.2 Capital Structure. The authorized capital stock of HISCO consists of 17,000,000 shares of Common Stock, $.01 par value, of which 3,894,396 shares are issued and outstanding, inclusive of 2,500,000 HISCo Founders Shares, 1,500,000 shares of which are to be repurchased by HISCo immediately prior to the Effective Time of the Merger as provided in Section 6.09, and 5,000,000 shares of Preferred Stock, $.01 par value, of which no shares are issued and outstanding. All of the issued and outstanding HISCo Common Stock is owned of record and beneficially by the stockholders as set forth on Schedule 3.2 attached hereto. All of the outstanding shares of HISCo Common Stock were issued in compliance with applicable federal and state securities laws, and no further registration, qualification or other compliance under such securities laws is required. All of the outstanding shares of HISCo Common Stock are validly issued, fully paid and nonassessable and not subject to preemptive rights created by statute, HISCo's Certificate of Incorporation or By-laws or any agreement to which HISCo is a party or is bound. There are 312,829 HISCo Options outstanding, which are owned of record and beneficially by the holders thereof as set forth on Schedule 3.2 attached hereto, all of which HISCo Options are to be cancelled immediately prior to the 6 12 Effective Time of the Merger as provided in Section 6.10. The authorized capital stock of HSA consists of 1,000 shares of common stock, $.01 par value, of which 1,000 shares are issued and outstanding, all of which are owned by HISCo. Except for the foregoing, there are no equity securities of any class of HISCo or HSA or any security exchangeable or convertible into or exercisable for such equity securities, issued, reserved for issuance or outstanding. There are no other options, warrants, calls, rights, commitments or agreements of any character to which HISCo or HSA is a party or by which they are bound obligating HISCo or HSA to issue, deliver or sell, or cause to be issued, delivered or sold, additional shares of capital stock of HISCo or HSA or obligating HISCo or HSA to grant, extend or enter into any such option, warrant, call, right, commitment or agreement. There are no voting trusts or other agreements or understandings with respect to the shares of capital stock of HISCo or HSA. 3.3 Equity Investments. Neither HISCo nor HSA owns, directly or indirectly, any equity interest in any corporation, partnership, joint venture, trust or other business entity; provided, however, that HISCo owns all of the outstanding capital stock of HSA. 3.4 Authority. Each of HISCo and HSA has all requisite corporate power and authority to enter into this Agreement and, subject to approval of this Agreement by the stockholders of HISCo and by HISCo in its capacity as the sole stockholder of HSA, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by the Board of Directors of each of HISCo and HSA, subject to such approval by the stockholders of each of HISCo and HSA. This Agreement has been duly executed and delivered by each of HISCo and HSA and, subject to such approval by the stockholders of each of HISCo and HSA, constitutes a valid and binding obligation of each of HISCo and HSA, enforceable against each of HISCo and HSA in accordance with its terms, except as such terms may be (i) limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally (including fraudulent transfer laws), and (ii) subject to general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered in a proceeding in equity or at law). Subject to satisfaction of the conditions set forth in Sections 7.1 and 7.3, the execution and delivery of this Agreement do not, and the consummation of the transactions contemplated hereby will not, conflict with, or result in any violation of or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or 7 13 acceleration of any obligation or to loss of a material benefit under (i) any provision of the Certificate of Incorporation or Bylaws of HISCo or HSA or (ii) any Material Agreement or permit, license, judgment, order, statute, rule or regulation applicable to either HISCo or HSA or their respective properties or assets, other than any such conflicts, violations, defaults, terminations, cancellations or accelerations which individually or in the aggregate would not have a Material Adverse Effect on HISCo or HSA. 3.5 Governmental Consents. No consent, approval, order or authorization of, or registration, declaration or filing with, any court, administrative agency or commission or other governmental authority or instrumentality (a "Governmental Entity"), is required by or with respect to HISCo or HSA in connection with the execution and delivery of this Agreement by HISCo and HSA or the consummation by HISCo and HSA of the transactions contemplated hereby, except for (i) the filing of a Certificate of Merger with the Secretary of State of the State of Delaware, and appropriate documents with the relevant authorities of other states in which HISCo or HSA is qualified to do business, (ii) such consents, approvals, orders, authorizations, registrations, declarations and filings as may be required under applicable state securities laws and the laws of any foreign country and (iii) such other consents, authorizations, filings, approvals and registrations which if not obtained or made would not have a Material Adverse Effect on HISCo or HSA. 3.6 Financial Statements. HISCo has furnished to HMS: (i) the consolidated balance sheet of HISCo as of October 31, 1996 (the "1996 Consolidated Balance Sheet") and the related consolidated statements of earnings, stockholders' equity and cash flows for the year then ended (together with the 1996 Consolidated Balance Sheet, the "1996 Consolidated Financial Statements"), certified by Ernst & Young LLP, (ii) the unaudited balance sheet of HSA as of October 31, 1996 (the "1996 HSA Balance Sheet") and the related statements of earnings of HSA for the year then ended, certified by Controller of HSA (together with the 1996 HSA Balance Sheet, the "1996 HSA Financial Statements"), and (iii) the unaudited balance sheet of HSA as of January 31, 1997 (the "January Balance Sheet"), and the related statement of earnings of HSA for the three months then ended, certified by the Controller of HSA (together with the January Balance Sheet, the "Interim Financial Statements"). The 1996 Consolidated Financial Statements and 1996 HSA Financial Statements (including any related schedules and/or notes, if any) and the Interim Financial Statements are complete and correct in all material respects and have been prepared in accordance with generally accepted accounting principles, consistently applied ("GAAP") and, in the case of the Interim Financial Statements, subject to normal year-end adjustments. The 1996 Consolidated 8 14 Balance Sheet and 1996 HSA Balance Sheet fairly present the consolidated financial position of HISCo and the financial position of HSA as of their respective dates, and the 1996 Consolidated Financial Statements and the 1996 HSA Financial Statements fairly present the consolidated results of operations of HISCo and the unconsolidated results of operations of HSA, respectively, for the period then ended. Except as described in Schedule 3.6 hereto, the Interim Financial Statements are complete and correct in all material respects, fairly present the financial position and earnings of HSA at the dates and for the periods presented, and have been compiled in accordance with GAAP (except that the Interim Financial Statements are subject to normal year-end adjustments which, both individually and in the aggregate, will not differ materially and adversely from the Interim Financial Statements). Except as described in Schedule 3.6 hereto, there has been no material adverse change in the operations or condition (financial or other) of HISCo since October 31, 1996 or HSA since January 31, 1997. Except as reflected in the 1996 Consolidated Financial Statements or the Interim Financial Statements, neither HISCo nor HSA had any obligations or liabilities, absolute, accrued or contingent, as of October 31, 1996 and January 31, 1997, respectively, that are material to the business or assets of either HISCo or HSA taken as a whole other than performance obligations under contracts or agreements with customers. 3.7 Absence of Changes. Since October 31, 1996 and January 31, 1997, respectively, neither HISCo nor HSA have, except as disclosed on Schedule 3.7 attached hereto: (a) suffered any changes in its condition (financial or otherwise), net worth, assets, properties, obligations or liabilities which, in the aggregate, have a Material Adverse Effect on HISCo or HSA or become aware of any event which may result in any such Material Adverse Effect; (b) issued, or authorized for issuance, or entered into any commitment to issue, any equity security, bond, note or other security of HISCo or HSA, except for those stock options set forth on Schedule 3.7 attached hereto; (c) incurred additional debt for borrowed money, except in the ordinary and usual course of business; (d) paid any obligation or liability, or discharged, settled or satisfied any claim, lien or encumbrance, except for current liabilities in the ordinary and usual course of business; 9 15 (e) declared, promised, or paid any dividend, payment or other distribution on or with respect to any share of HISCo Common Stock; (f) purchased, redeemed or otherwise acquired or committed itself to acquire, directly or indirectly, any share or shares of HISCo Common Stock, except as contemplated in this Agreement; (g) mortgaged, pledged, or otherwise, voluntarily or involuntarily encumbered any of its assets or properties, except for liens for current taxes which are not yet due and payable and purchase-money liens arising out of the purchase or sale of products or services made in the ordinary and usual course of business consistent with past practices; (h) transferred, assigned, licensed, conveyed or liquidated any of its assets or entered into any transaction or incurred any liability or obligation which affected its assets, other than transactions occurring in the ordinary and usual course of business consistent with past practices; (i) suffered any material destruction, damage or loss relating to its assets whether or not covered by insurance; (j) committed, suffered, permitted or incurred any default in any liability or obligation which, in the aggregate, has had or will have any Material Adverse Effect upon HISCo or HSA; (k) made any expenditure or commitment for the purchase, acquisition, construction or improvement of a capital asset, except in the ordinary and usual course of business consistent with past practices; (l) sold, assigned, transferred or conveyed, or committed itself to sell, assign, transfer or convey, any Proprietary Rights (as defined in Section 3.14), except in the ordinary course of business consistent with past practices (including non-exclusive licensing in connection with the sale of equipment); (m) effected or agreed to effect any amendment or supplement to any employee benefit plan or arrangement or paid, agreed to pay or incurred any obligation for any payment for, any contribution or other amount to or with respect to, any employee benefit plan, or paid any bonus to, or granted any increase in the compensation of, its officers, agents or employees, or made any increase in the pension, retirement or other benefits of its directors, officers, agents or other employees; 10 16 (n) paid or committed itself to pay to or for the benefit of any of its directors, officers, employees or stockholders any compensation of any kind other than wages, salaries and benefits at times and rates in effect prior to October 31, 1996 or January 31, 1997, respectively, except for increases and bonuses to employees in the ordinary course of business consistent with past practices; (o) effected or committed itself to effect any amendment or modification in its Certificate of Incorporation or By-laws, except as contemplated in this Agreement, or to any change in the terms of any contract or instrument to which it is a party which may have a Material Adverse Effect on HISCo or HSA; (p) incurred any other material liability or obligation or entered into any transaction other than in the ordinary course of business consistent with past practices; or (q) received any notices, or has reason to believe, that any supplier or customer of HISCo or HSA has taken or contemplates any steps which could disrupt the business relationship of HISCo or HSA with said supplier or customer or could result in the diminution in the value of HISCo or HSA as a going concern. 3.8 Properties. Neither HISCo nor HSA owns any fee interest in real property. The 1996 Consolidated Financial Statements and the Interim Financial Statements reflect all of the personal property used by HISCo or HSA in its business or otherwise held by HISCo or HSA, as of their respective dates, except for (i) property acquired or disposed of in the ordinary and usual course of the business of HISCo or HSA since the dates of the 1996 Consolidated Balance Sheet and the January Balance Sheet, and (ii) property not required under generally accepted accounting principles to be reflected thereon. Each of HISCo and HSA has good and marketable title to all assets and properties listed on the 1996 Consolidated Balance Sheet and the January Balance Sheet and thereafter acquired, free and clear of any imperfections of title, security interests, liens, pledges, claims, charges, escrows, encumbrances, options, rights of first refusal, mortgages, indentures, easements, licenses, security agreements or other agreements, arrangements, contracts, commitments, understandings or obligations (collectively, the "Encumbrances"), except (i) liens for current taxes not yet due and payable or (ii) Encumbrances referred to in the 1996 Consolidated Balance Sheet, the January Balance Sheet or in Schedule 3.8 attached hereto (provided that the foregoing representation does not extend to Proprietary Rights as to which Section 3.13 applies). 11 17 3.9 Taxes. Each of HISCo and HSA has duly filed or caused to be filed with the appropriate United States, state, local and foreign governmental agencies all tax returns and reports required to be filed, and all such reports are true, correct and complete in all material respects. Each of HISCo and HSA has paid all Taxes shown thereon as owing. All Taxes due through the date of the Closing will have been fully paid by that date or provided for by adequate reserves. The 1996 Consolidated Financial Statements and the Interim Financial Statements reflect all Taxes accrued through the period indicated thereon. Neither HISCo nor HSA is a party to any pending action or proceeding, nor is any such action or proceeding threatened by any governmental authority for the assessment or collection of Taxes, and no claim for assessment or collection of Taxes has been asserted against HISCo or HSA. For purposes of this Agreement, an action shall be deemed pending, and a claim shall be deemed to have been asserted, only after service of summons or other notice has been made upon HISCo or HSA. 3.10 Compliance with Law. Except for possible minor exceptions, the curing or non-curing of which would not have a Material Adverse Effect on HISCo or HSA, the business of HISCo and HSA has been conducted in accordance with all applicable laws, regulations, orders and other requirements of governmental authorities. 3.11 Litigation. Except as otherwise set forth on Schedule 3.11 attached hereto, there is no claim, dispute, action, proceeding, suit or appeal, or investigation, at law or in equity, pending against HISCo or HSA or affecting any of its assets or properties (including the Proprietary Rights), before any court, agency, authority, arbitration panel or other tribunal and none has been threatened against HISCo or HSA. There are no facts which, if known to stockholders, customers, governmental authorities or other persons, would be a basis for any such claim, dispute, action, proceeding, suit or appeal or investigation which would have a Material Adverse Effect on HISCo or HSA. Neither HISCo nor HSA is subject to any order, writ, injunction or decree of any court, agency, authority, arbitration panel or other tribunal. 3.12 Material Agreements. Schedule 3.12 attached hereto consists of a true and complete list of all Material Agreements relating to HISCo or HSA, and not listed on another schedule hereto, to which HISCo or HSA is a party and which have been entered into by HISCo or HSA after June 30, 1995.

Each of the Material Agreements is a legal, binding and enforceable obligation by or against HISCo or HSA, assuming in the case of any such agreement, that it is a legal, binding and enforceable obligation of the other party(ies) thereto, enforceable in accordance with its terms, except as such terms may be (i) limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally (including fraudulent transfer laws), and (ii) subject to general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered in a proceeding in equity or at law). 3.16 Information Supplied.
