At the Effective Time, as a result of the Merger and without any action on the part of the holder of any capital stock of the Company: (a) Merger Consideration. Subject to Section 4.2, each share of the Common Stock, par value $0.01 per share, of the Company (the "Shares"), issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares (as defined in Section 4.3(a)), Shares owned by Parent, Merger Sub, or any other direct or indirect subsidiary of Parent (collectively, the "Parent Companies") or Shares that are owned by the Company or any direct or indirect subsidiary of the Company and in each case not held on behalf of third parties (collectively, "Excluded Shares")) shall be converted into, and become exchangeable for the following (the "Merger Consideration"): the right to receive (i) $7.50 in cash (the "Cash Consideration"), without interest thereon, or (ii) 0.31496 shares of Common Stock, par value $0.01 per share (the "Parent Common Stock"), of Parent (the "Stock Consideration"). At the Effective Time, all Shares shall no longer be outstanding and shall be canceled and retired and shall cease to exist, -3- 9 and each certificate (a "Certificate") previously representing any of such Shares (other than Excluded Shares and Dissenting Shares) shall thereafter represent only the right to receive the Merger Consideration and the right, if any, to receive pursuant to Section 4.2(e) cash in lieu of fractional shares into which such Shares have been converted pursuant to this Section 4.1(a) and any dividends or other distributions pursuant to Section 4.2(c). (b) Cancellation of Shares. Each Share issued and outstanding immediately prior to the Effective Time and owned by any of the Parent Companies or owned by the Company or any direct or indirect subsidiary of the Company (other than Shares that are in each case owned on behalf of third parties), shall, by virtue of the Merger and without any action on the part of the holder thereof, (i) cease to be outstanding, (ii) be canceled and retired without payment of any consideration therefor, and (iii) cease to exist. (c) Merger Sub. At the Effective Time, each share of Common Stock, par value $1 per share, of Merger Sub, issued and outstanding immediately prior to the Effective Time, shall remain outstanding and each certificate therefor shall continue to evidence one share of Common Stock, par value $1 per share, of the Surviving Corporation. 4.2. Cash Election Procedures. (a) Allocation. Notwithstanding anything in this Agreement to the contrary, the maximum number of Shares (the "Cash Election Number") to be converted into the right to receive Cash Consideration in the Merger shall be the largest whole number less than or equal to (i) 49.9 percent of the number of Shares issued and outstanding immediately prior to the Effective Time less (ii) the number of Shares to be canceled in accordance with Section 4.1(b). The number of Shares to be converted into the right to receive Stock Consideration in the Merger (the "Stock Election Number") shall be equal to the number of Shares issued and outstanding immediately prior to the Effective Time less the sum of (i) the Cash Election Number and (ii) the number of Shares to be canceled in accordance with Section 4.1(b). (b) Election Procedures. (i) As of the Effective Time, Parent shall deposit, or shall cause to be deposited, with an exchange agent selected by Parent, with the Company's prior approval, which shall not be unreasonably withheld (the "Exchange Agent"), for the benefit of the former holders of Shares, certificates representing the shares of Parent -4- 10 Common Stock and any cash and any dividends or other distributions with respect to the Parent Common Stock to be issued or paid pursuant to Sections 4.1 and 4.2(c) in exchange for outstanding Shares upon due surrender of the Certificates pursuant to the provisions of this Article IV (such cash and certificates for shares of Parent Common Stock, together with the amount of any dividends or other distributions payable with respect thereto, being hereinafter referred to as the "Exchange Fund"). (ii) Subject to allocation and proration in accordance with the provisions of this Section 4.2, each record holder of Shares (other than Excluded Shares and Dissenting Shares) issued and outstanding immediately prior to the Election Deadline (as defined below) shall be entitled (A) to elect to receive in respect of each such Share (x) Cash Consideration (a "Cash Election") or (y) Stock Consideration (a "Stock Election") or (B) to indicate that such record holder has no preference as to the receipt of Cash Consideration or Stock Consideration for such Shares (a "Non-Election"). Shares in respect of which a Non-Election is made (including shares in respect of which such an election is deemed to have been made pursuant to this Section 4.2 and Section 4.3 (collectively, "Non-Election Shares")) shall be deemed by Parent, in its sole and absolute discretion, subject to Sections 4.2(b)(v)-(vii), to be, in whole or in part, Shares in respect of which Cash Elections or Stock Elections have been made. (iii) Elections pursuant to Section 4.2(b)(ii) shall be made on a form and with such other provisions to be reasonably agreed upon by the Company and Parent (a "Form of Election") to be provided by the Exchange Agent for that purpose to holders of record of Shares (other than holders of Excluded Shares and Dissenting Shares), together with appropriate transmittal materials, at the time of mailing to holders of record of Shares of the Prospectus-Proxy Statement (as defined in Section 6.3) in connection with the stockholders' meeting referred to in Section 6.4. Elections shall be made by mailing to the Exchange Agent a duly completed Form of Election. To be effective, a Form of Election must be (x) properly completed, signed, and submitted to the Exchange Agent at its designated office, by 5:00 p.m., New York City time, on the Business Day that is two Business Days prior to the Closing Date (which date shall be publicly announced by Parent as soon as practicable but in no event less than five Business Days prior to the Closing Date) (the "Election Deadline") and (y) accompanied by the Certificate(s) representing the Shares as to which the election is being -5- 11 made (or by an appropriate guarantee of delivery of such Certificate(s) by a commercial bank or trust company in the United States or a member of a registered national security exchange or of the National Association of Securities Dealers, Inc., provided that such Certificates are in fact delivered to the Exchange Agent within three Business Days after the date of execution of such guarantee of delivery). The Company shall use commercially reasonable efforts to make a Form of Election available to all persons who become holders of record of Shares (other than Excluded Shares and Dissenting Shares) between the date of mailing described in the first sentence of this Section 4.2(b)(iii) and the Election Deadline. Parent shall determine, in its sole and absolute discretion, which authority it may delegate in whole or in part to the Exchange Agent and whether Forms of Election have been properly completed, signed, and submitted or revoked. The decision of Parent (or the Exchange Agent, as the case may be) in such matters shall be conclusive and binding. Parent shall make reasonable efforts to, or shall make reasonable efforts to cause the Exchange Agent to, notify holders of Shares of defects in any Form of Election submitted to the Exchange Agent. A holder of Shares that does not submit an effective Form of Election prior to the Election Deadline shall be deemed to have made a Non- Election. (iv) An election may be revoked, but only by written notice received by the Exchange Agent prior to the Election Deadline. Any Certificate(s) representing Shares that have been submitted to the Exchange Agent in connection with an election shall be returned without charge to the holder thereof in the event such election is revoked as aforesaid and such holder requests in writing the return of such Certificate(s). Upon any such revocation, unless a duly completed Form of Election is thereafter submitted in accordance with paragraph (b)(ii), such Shares shall be Non-Election Shares. In the event that this Agreement is terminated pursuant to the provisions hereof and any Shares have been transmitted to the Exchange Agent pursuant to the provisions hereof, such Shares shall promptly be returned without charge to the person submitting the same. (v) In the event that the aggregate number of Shares in respect of which Cash Elections have been made (collectively, the "Cash Election Shares") exceeds the Cash Election Number, all shares in respect of which Stock Elections have been made (the "Stock Election Shares") and all Non-Election Shares in respect of which Stock Elections are deemed to have been made (it being understood that in such case all Non-Election Shares shall be deemed to be shares in respect of which Stock Elections have been -6- 12 made) shall be converted into the right to receive Stock Consideration, and all Cash Election Shares shall be converted into the right to receive Stock Consideration or Cash Consideration in the following manner: (A) a cash proration factor (the "Cash Proration Factor") shall be determined dividing the Cash Election Number by the total number of Cash Election Shares; the quotient shall be carried to five decimal places. (B) the number of Cash Election Shares to be converted into the right to receive cash shall be determined by multiplying the Cash Proration Factor by the total number of Shares covered by each Cash Election. (C) each Share covered by a Cash Election and not converted into a right to receive cash as set forth above shall be converted into Stock Consideration in the Merger. (vi) In the event that the aggregate number of Stock Election Shares exceeds the Stock Election Number, all Cash Election Shares and all Non-Election Shares in respect of which Cash Elections are deemed to have been made (it being understood that in such case all Non-Election Shares shall be deemed to be Shares in respect of which Cash Elections have been made) shall be converted into the right to receive Cash Consideration, and all Stock Election Shares shall be converted into the right to receive Stock Consideration or Cash Consideration in the following manner: (A) a stock proration factor (the "Stock Proration Factor") shall be determined by dividing the Stock Election Number by the total number of Stock Election Shares; the quotient shall be carried to five decimal places. (B) the number of Stock Election Shares to be converted into the right to receive cash shall be determined by multiplying the Stock Proration Factor by the total number of Shares covered by each Stock Election. (C) each Share covered by a Stock Election and not converted into a right to receive Parent Common Stock as set forth above shall be converted into the right to receive cash in the Merger. (vii) In the event that neither clause (v) nor clause (vi) of this Section 4.2(b) is applicable, (x) Non-Election Shares shall be deemed Stock Election Shares -7- 13 such that the total number of Stock Election Shares equals the Stock Election Number and any remaining Non-Election Shares shall be deemed Cash Election Shares, (y) all Cash Election Shares and all Non-Election Shares in respect of which Cash Elections are deemed to have been made shall be converted into the right to receive Cash Consideration, and (z) all Stock Election Shares and all Non-Election Shares in respect of which Stock Elections are deemed to have been made shall be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests). (viii) The Exchange Agent, in consultation with Parent and the Company, shall (A) periodically, upon request of Parent or the Company, provide information with respect to Forms of Election received and (B) make all computations to give effect to this Section 4.2. (c) Distributions with Respect to Unexchanged Shares; Voting. (i) All shares of Parent Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by Parent in respect of the Parent Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of Parent Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the Parent Common Stock shall be paid to any holder of any unsurrendered Certificate until such Certificate is surrendered for exchange in accordance with this Article IV. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be issued and/or paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (A) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender. (ii) Holders of unsurrendered Certificates shall be entitled to vote, after the Effective Time, at any meeting of stockholders of Parent, the number of whole shares of Parent Common Stock represented by such Certificates, regardless of whether such holders have -8- 14 exchanged their Certificates. (d) Transfers. After the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time. (e) Fractional Shares. Notwithstanding any other provision of this Agreement, no fractional shares of Parent Common Stock will be issued and any holder of Shares entitled to receive a fractional share of Parent Common Stock but for this Section 4.2(e) shall be entitled to receive a cash payment in lieu thereof, which payment shall represent such holder's proportionate interest in a net proceeds from the sale by the Exchange Agent on behalf of all such holders of the aggregate fractional shares of Parent Common Stock that such holders otherwise would be entitled to receive. Any such sale shall be made by the Exchange Agent, at the market price, within five Business Days after the date upon which the Certificate(s) (or affidavit(s) of loss in lieu thereof) that would otherwise result in the issuance of such fractional shares of Parent Common Stock have been received by the Exchange Agent. Any costs, including, but not limited to, brokerage commissions of such sales shall be borne by Parent. (f) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof and any Parent Common Stock) that remains unclaimed by the former stockholders of the Company for 180 days after the Effective Time shall be paid to Parent. Any stockholders of the Company who have not theretofore complied with this Article IV shall thereafter look only to Parent for payment of their shares of Parent Common Stock and any cash, dividends, and other distributions in respect thereof payable and/or issuable pursuant to Section 4.1 and Section 4.2(c) upon due surrender of their Certificates (or affidavits of loss in lieu thereof), in each case, with out any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation, the Exchange Agent, or any other person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. (g) Lost, Stolen, or Destroyed Certificates. In the event any Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen, or destroyed and, if required by Parent, the posting by such person of a bond in customary amount as indemnity against -9- 15 any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen, or destroyed Certificate the shares of Parent Common Stock and any cash payable and any unpaid dividends or other distributions in respect thereof pursuant to Section 4.2(c) upon due surrender of and deliverable in respect of the Shares represented by such Certificate pursuant to this Agreement. (h) Affiliates. Notwithstanding anything herein to the contrary, Certificates surrendered for exchange by any "affiliate" (as determined pursuant to Sec tion 6.8) of the Company shall not be exchanged until Parent has received a written agreement from such person as provided in Section 6.8. 4.3. Dissenters' Rights. (a) Notwithstanding anything in this Agreement to the contrary, Shares which were outstanding on the date for the determination of stockholders entitled to vote on the adoption of this Agreement and which were not voted in favor of or were voted against the adoption of this Agreement and the holders of which have demanded that the Company purchase such shares at their fair value in accordance with Section 262 of the DGCL and have not failed to perfect or shall not have effectively withdrawn or lost their rights to purchase for cash under the DGCL (the "Dissenting Shares") shall not be converted into the Merger Consideration, but instead, the holders thereof shall be entitled to have their shares purchased by the Company for cash at the fair value of such Company Dissenting Shares as agreed upon or determined in accordance with the provisions of Section 262 of the DGCL; provided, however, that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost his, her, or its right to appraisal and payment under the DGCL, such holder's Shares shall thereupon be deemed to have been converted, at the Effective Time, as No Election Shares, into the Merger Consideration set forth in Section 4.1, without any interest thereon. (b) The Company shall provide Parent (i) prompt notice of any demands pursuant to Section 262 of the DGCL received by the Company, withdrawals of such demands, and any other instruments served pursuant to the DGCL and received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands under Section 262 of the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any such demands for appraisal or -10- 16 offer to settle or settle any such demands. (c) For purposes of Section 4.2, Dissenting Shares shall be deemed to be Shares in respect of which Cash Elections have been made. 4.4. Adjustments to Prevent Dilution. In the event that the Company changes the number of Shares or securities convertible into, exchangeable for, or exercisable for Shares, or Parent changes the number of shares of Parent Common Stock or securities convertible into, exchangeable for, or exercisable for shares of Parent Common Stock, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Merger Consideration shall be equitably adjusted to reflect such reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction. 4.5 Company Warrants. At the Effective Time, each outstanding warrant to purchase Shares shall, subject to the receipt of the consents referred to in Section 7.2(p), be canceled in exchange for the issuance, at the Closing, of the number of shares of Parent Common Stock equal to (a) the product of (i) the aggregate number of Shares for which such warrant was immediately prior to the Effective Time exercisable multiplied by (ii) 0.31496; minus (b) (i) the quotient of (A) the aggregate exercise price of such warrant immediately prior to the Effective Time divided by (B) $23.8125; provided that no fractional interests in a share of Parent Common Stock shall be issued, and any holder of a warrant entitled to a fractional share under this Section 4.5 shall be entitled to a cash payment in lieu thereof, as provided in Section 4.2(e). ARTICLE V Representations and Warranties 5.1. Representations and Warranties of the Company.

Each of the Company and its Subsidiaries is a corporation duly organized, validly existing, and in good -11- 17 standing under the laws of its respective jurisdiction of organization and has all requisite corporate or similar power and authority to own and operate its properties and assets and to carry on its business as presently conducted and is qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the ownership or operation of its properties or conduct of its business requires such qualification. The Company has made available to Parent a complete and correct copy of the Company's and its Subsidiaries' respective certificates of incorporation and by-laws, each as amended to date. The Company's and its Subsidiaries' certificates of incorporation and by-laws so delivered are in full force and effect.

(ii) The execution, delivery, and performance of this Agreement by the Company do not, and the consummation by the Company of the Merger and the other transactions contemplated hereby will not, constitute or result in a breach or violation of, or a default under, the respective certificate of incorporation or by-laws of the Company or any of its Subsidiaries. On the date of this Agreement, the execution, delivery, and performance of this Agreement by the Company do not, and the consummation by the Company of the Merger and the other transactions contemplated hereby will not, constitute or result in, (A) a breach or violation of, or a default under, the acceleration of any obligations or the creation of a lien, pledge, security interest, or other encumbrance on the assets of the Company or any of its Subsidiaries (with or without notice, lapse of time, or both) pursuant to any agreement, lease, contract, note, mortgage, indenture, arrangement, or other obligation ("Contracts") binding upon the Company or any of its Subsidiaries or any Law or governmental or non-governmental permit or license to which the Company or any of its Subsidiaries is subject, or (B) any change in the rights or obligations of any party under any of the Contracts.

(b) Parent shall cause the Surviving Corporation to maintain in effect for six years from the Effective Time policies of directors' and officers' liability insurance containing terms and conditions which are not materially less advantageous than those policies maintained by the Company at the date of this Agreement, with respect to matters occurring at or prior to the Effective Time, to the extent available, and having at least the same amount of coverage as the current directors' and officers' liability insurance of the Company, as provided by the Company to Parent; provided that (i) the Surviving Corporation shall not be required to spend an amount in any year in excess of 200% of the annual aggregate premiums currently paid by the Company for such insurance; and provided further, that if the annual premiums of such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with the best -38- 44 coverage available in the reasonable judgment of the board of directors of Parent following the Merger, for a cost not exceeding such amount; and (ii) such policies may in the sole discretion of the Surviving Corporation be one or more "tail" policies for all or any portion of the full six year period. 6.11.

Benefits. (a) Stock Options. Except as otherwise provided in Section 6.12(c), in the sole discretion of the Surviving Corporation, any option under any stock option plan of the Company may be assumed by the Surviving Corporation, or may be replaced with a cash incentive program of the Surviving Corporation or Parent that preserves the spread existing at the Effective Time on any Shares of the Company for which the option involved is not then otherwise exercisable (without regard to any acceleration related to the Merger) and that provides for a subsequent cash pay out in accordance with the same exercise/vesting schedule applicable to the Company Shares subject to the option. Any outstanding option that is neither assumed nor replaced with a cash alternative, as provided in this Section 6.12(a), shall be canceled at the Effective Time. (b) Employee Benefits.

(c) Limited Accelerated Vesting and Exercisability. Parent and Merger Sub agree that, with respect to options issued by the Company under its Stock Plans that will not be fully vested and exercisable at the Effective Time, the Company and Parent shall mutually agree upon accelerating the vesting and exercisability of certain of the unvested and unexercisable options (in an amount agreed between the Company and -39- 45 Parent) of certain of the Company's employees and consultants (as mutually agreed between Company and Parent), as long as such employee or consultant agrees that he or she will execute a release of liability in a form reasonably acceptable to Parent and/or the Surviving Corporation if such employee is terminated by Parent or Merger Sub after the Effective Date; provided, however, that in no event shall the total value (calculated as $7.50 minus the exercise price) of such options to be accelerated under this Section 6.12(c) exceed $671,915.00.

This Agreement may be terminated and -47- 53 the Merger may be abandoned at any time prior (whether before or after adoption of this Agreement by the stockholders of the Company) to the Effective Time by action of the Board of Directors of Parent if (i) the board of directors of the Company shall have with drawn or adversely modified its approval or recommendation of this Agreement or failed to reconfirm its recommendation of this Agreement within seven Business Days after a written request by Parent to do so, (ii) there has been a material breach by the Company of any representation, warranty, covenant, or agreement contained in this Agreement that is not curable or, if curable, is not cured within 30 days after written notice of such breach is given by Parent to the Company, or (iii) the Company or any Representatives of the Company shall take any of the actions that would be proscribed by Section 6.2. 8.5. Effect of Termination and Abandonment. (a) In the event of termination of this Agreement and the abandonment of the Merger pursuant to this Article VIII, this Agreement (other than as set forth in Section 9.1) shall become void and of no effect with no liability on the part of any party hereto (or of any of its directors, officers, employees, agents, legal and financial advisors, or other representatives) except as otherwise provided herein; provided, however, that except as otherwise provided herein, no such termination shall relieve any party hereto of any liability or damages resulting from any willful or intentional material breach of this Agreement.

("COMPS.COM Common Stock"). The undersigned acknowledges that the undersigned may be deemed an "affiliate" of COMPS.COM within the meaning of Rule 145 promulgated under the Securities Act of 1933 (the "Securities Act"), although nothing contained in this letter should be construed as an admission of such fact. As a result of the terms of an Agreement and Plan of Merger among CoStar Group, Inc. ("CoStar Group"), Acq Sub. Inc. and COMPS.COM, Inc. dated November 3, 1999 (the "Merger Agreement"), COMPS.COM will be merged with and into Acq Sub, Inc (the "Merger"). As a result of the Merger, the undersigned may receive shares of Common Stock, par value $0.01 per share, of CoStar Group, Inc. ("CoStar Group Common Stock") in exchange for shares of COMPS.COM Common Stock. A. In connection with the foregoing, the undersigned represents, warrants and agrees as follows: 1. The undersigned will not make any sale, transfer or other disposition of the CoStar Group Common Stock received in connection with the Merger in violation of the Securities Act, including the rules and regulations under the Securities Act. 2. The undersigned has been advised that the issuance of CoStar Group Common Stock to the undersigned as a result of the Merger has been registered under the Securities Act on a registration statement on Form S-4. The undersigned has also been advised that, because at the time the Merger was submitted for a vote of stockholders of COMPS.COM, the undersigned may have been an "affiliate" of COMPS.COM within the meaning of Rule 145 and that therefore the distribution by the undersigned of the CoStar Group Common Stock received as a result of the Merger must be held by the undersigned indefinitely unless (a) such distribution has been registered under the Securities Act, (b) such distribution is made in conformity with Rule 145, or (c) such distribution is pursuant to a transaction which, in the opinion of counsel for CoStar Group or other counsel reasonably satisfactory to CoStar Group or as described in a 61 "no-action" or interpretative letter from the staff of the Securities and Exchange Commission ("SEC"), is not required to be registered under the Securities Act. In the event of a sale or other disposition by the undersigned of CoStar Group Common Stock pursuant to Rule 145, the undersigned will supply CoStar Group with evidence of compliance with such Rule in the form reasonably requested by CoStar Group, including, if requested, a customary broker's certification, a customary seller's certification and an opinion of counsel reasonably acceptable to CoStar Group. 3. The undersigned has carefully read this letter and the Merger Agreement and has discussed the requirements of the Merger Agreement and other limitations upon the sale, transfer or other disposition of CoStar Group Common Stock to be received in connection with the Merger, to the extent the undersigned has determined to be necessary or appropriate, with counsel for the undersigned and/or counsel for COMPS.COM. 4. If the undersigned is other than a natural person, the person executing this letter is authorized to do so on behalf of the undersigned. B. Furthermore, in connection with the foregoing, the undersigned understands and agrees as follows: 1. CoStar Group is under no obligation to maintain the effectiveness of any registration statement under the Securities Act for purposes of resale of CoStar Group Common Stock by the undersigned. 2. CoStar Group is under no obligation to take any action to make available any exemption from registration to permit the resale of the CoStar Group Common Stock (except as provided by A.2. above). 3. Stop transfer instructions will be given to the transfer agent for CoStar Group with respect to the shares of CoStar Group Common Stock received by the undersigned as a result of the Merger, and there will be placed on the certificates representing such shares, or any certificates delivered in substitution therefor, a legend stating in substance the following: "The shares represented by this certificate were issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares represented by this certificate may only be transferred in accordance with the terms of an agreement dated ________, between the registered holder hereof and CoStar Group, a copy of which agreement is on file at the principal offices of CoStar Group." 4. Unless the transfer by the undersigned of CoStar Group Common Stock has been registered under the Securities Act or is a sale made in conformity with the provisions of Rule 145 and the terms hereof, CoStar Group 62 reserves the right to put the following legend on the certificates issued to any transferee of the undersigned: "The shares represented by this certificate have not been registered under the Securities Act of 1933 and were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares have been acquired by the holder not with a view to, or for resale in connection with, any distribution thereof within the meaning of Securities Act of 1933 and may not be sold, pledged or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act of 1933." 5. The legends set forth above may be removed and substitute certificates delivered without any such legends only if the undersigned provides documentation reasonably requested by CoStar Group, which may include an opinion of counsel reasonably satisfactory to CoStar Group that the legend is not required by the Securities Act. 6. The undersigned hereby agrees to waive any registration rights in COMPS.COM Common Stock and/or CoStar Group Common Stock, including, without limitation, any registration rights provided by the Amended and Restated Investors Rights Agreement, dated February 9, 1998, or any predecessor or successor agreement. Very truly yours, By signing below, CoStar Group agrees as follows: From and after the Merger and for so long as is necessary in order to permit the above signatory to this letter (the "Holder") to sell the CoStar Group Common Stock held by the Holder pursuant to Rule 145 and, to the extent applicable, Rule 144 under the Securities Act, CoStar Group will use its commercially reasonable efforts to file on a timely basis all reports required to be filed by it pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, referred to in paragraph (c)(1) of Rule 144 under the Securities Act, in order to permit the Holder to sell the CoStar Group Stock held by it pursuant to the terms and conditions of Rule 145 and the applicable provisions of Rule 144.

As used in this opinion letter, the phrase "to our knowledge", or any similar expression or phrase with respect to our knowledge of matters of fact, means as to matters of fact that, based on the actual knowledge of individual attorneys within the firm responsible for handling current matters for the Company (and not including any constructive or imputed notice of any information), and after an examination of documents referred to herein and after inquiries of certain officers of the Company, no facts have been disclosed to us that have caused us to conclude that the opinions expressed are factually incorrect; but beyond that we have made no factual investigation for the purposes of rendering this opinion letter. Specifically, but without limitation, we have made no inquiries of securities holders or employees of the Company, other than such officers; and we have not searched the dockets of any courts or government agencies. This opinion letter relates solely to the laws of the State of California, the General Corporation Law of the State of Delaware (the "DGCL") and the federal law of the United States, and we express no opinion with respect to the effect or application of any other laws. Special rulings of authorities administering such laws or opinions of other counsel have not been sought or obtained. We have not examined the question of, and express no opinion as to, what law would govern the interpretation or enforcement of the Agreement, and our opinions with regard to such matters are based upon the assumption that the internal law of the State of California would govern the provisions thereof. Based upon our examination of and reliance upon the foregoing and subject to the limitations, exceptions, qualifications and assumptions set forth below and except as set forth in the Agreement or the Company Disclosure Letter, we are of the opinion that as of the date hereof: 1.

Except for (i) options and warrants to purchase an aggregate of _____ shares of Common Stock and (ii) rights under the ESPP. 4. The Company's execution and delivery of the Agreement, and its performance of its obligations thereunder and compliance by the Company with the terms of the Agreement, do not and will not violate any provision of any federal or California law, statute, rule or regulation applicable to the Company, the DGCL or any provision of the Company's Restated Certificate of Incorporation, as currently in effect, or the Company's Restated Bylaws, as currently in effect, and do not and will not conflict with or constitute a default under the provisions of any judgment, writ, decree or order specifically identified in the Company Disclosure Letter or the material provisions of any material agreement specifically identified in the Company Disclosure Letter. 5. We are not aware that there is any action, proceeding or governmental investigation pending or overtly threatened in writing against the Company, except as set forth in the Company SEC Reports, which (a) questions the validity of the Agreement or the right of the Company to enter into the Agreement or (b) would reasonably be expected to have a material adverse effect on its business or properties, taken as a whole. Our opinions expressed above are specifically subject to the following limitations, exceptions, qualifications and assumptions: A. We express no opinion as to the Company's compliance or noncompliance with applicable federal or state antifraud or antitrust statutes, laws, rules and regulations. B. We express no opinion concerning the past, present or future fair market value of any securities. C. We express no opinion as to your compliance with any Federal or state law relating to your legal or regulatory status or the nature of your business. D. With respect to our opinion in Paragraph 4, we have not conducted any special investigation of laws, and such opinions are limited to the DGCL and such California and 66 CoStar Group, Inc. [date of closing] Page 4 United States laws as in our experience are of general application to transactions of the sort contemplated by the Agreement. Without limitation, such opinions do not extend to licenses, permits, approvals, etc. necessary for the conduct of the Company's business. Further, we express no opinion as to the effect of or compliance with any state or federal laws or regulations applicable to the transactions contemplated by the Agreement because of the nature of the business of any party thereto other than the Company. In addition, with respect to our opinion in Paragraph 4, we have relied solely upon the representations of officers of the Company regarding the existence of facts that may result in a material default, etc., except to the extent that such material default, etc. would be apparent solely from an examination of the agreements. We have made no analysis with respect to the Company's compliance with any financial ratios and the like set forth in any real property lease, equipment lease or other agreements to which the Company is a party, and we express no opinion on the effect of the consummation of the transactions covered by the Agreement on the Company's compliance with such financial covenants. E. With respect to our opinion in Paragraph 3(b) that the issued and outstanding shares of Common Stock of the Company are fully paid, we have relied solely upon the representations concerning receipt by the Company of consideration for such shares made to us in certificates executed by officers of the Company. With respect to our opinion in Paragraph 3 as it relates to the valid issuance and the number of shares of outstanding Preferred Stock and Common Stock, the number of outstanding options to purchase shares of the Company's Common Stock and the existence of any other options, warrants, conversion privileges or other rights, we have relied solely on our review of corporate minutes and on written representations of the officers of the Company. F. We express no opinion as to the enforceability of Sections 6.2 or 8.5(b) in the Agreement or whether the enforceability of the indemnification and contribution obligations referred to in Section 6.10 of the Agreement may be limited by public policy underlying federal or state securities laws. G. We express no opinion as to limitations imposed by the DGCL, California law, federal law or general equitable principles upon the specific enforceability of any of the remedies, covenants or other provisions of the Agreement and upon the availability of injunctive relief or other equitable remedies, regardless of whether enforcement of the Agreement is considered a proceeding in equity or at law. H. We express no opinion as to the effect of California or Delaware court decisions, invoking statutes or principles of equity, which have held that certain covenants and provisions of agreements are unenforceable where (i) the breach of such covenants or provisions imposes restrictions or burdens upon a party, and it cannot be demonstrated that the enforcement of such restrictions or burdens is reasonably necessary for the protection of the other party, or (ii) 67 CoStar Group, Inc. [date of closing] Page 5 the other party's enforcement of such covenants or provisions under the circumstances would violate the other party's implied covenant of good faith and fair dealing, or (iii) the breach of such covenants or provisions is not a material breach of a material covenant or provision. I. We express no opinion as to the effect of Section 1670.5 of the California Civil Code or any other California law, federal law or equitable principle which provides that a court may refuse to enforce, or may limit the application of, a contract or any clause thereof which the court finds to have been unconscionable at the time it was made or contrary to public policy. J. We express no opinion as to the [un]enforceability under certain circumstances of provisions expressly or by implication waiving broadly or vaguely stated rights, unknown future rights, or defenses to obligations or rights granted by law, when such waivers are against public policy or prohibited by law. K. We express no opinion as to the [un]enforceability under certain circumstances of provisions to the effect that rights or remedies are not exclusive, that rights or remedies may be exercised without notice, that every right or remedy is cumulative and may be exercised in addition to or with any other right or remedy, that election of a particular remedy or remedies does not preclude recourse to one or more remedies, or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy. L. We express no opinion as to the validity, binding effect or enforceability of any provisions prohibiting waivers of any terms of the Agreement other than in writing, or prohibiting oral modifications thereof or modification by course of dealing. This opinion letter is rendered as of the date first written above solely for your benefit in connection with the Agreement and may not be delivered to, quoted or relied upon by any person other than you, or for any other purpose, without our prior written consent. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company.

RECITALS WHEREAS, COMPS.COM, Inc., a Delaware corporation (the "Company"), Parent, and Acq Sub, Inc. ("Merger Sub") have entered an Agreement and Merger Plan, dated as of November 3, 1999 (the "Agreement"), whereby the Company will be merged with and into Merger Sub (the "Merger") and the separate existence of the Company will thereafter cease, so that Merger Sub shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the "Surviving Corporation"). WHEREAS, a condition to the performance by Parent and Merger Sub of their obligations to effect the Merger Sub under the Agreement is that Pledgors enter into this Pledge Agreement, and Pledgors enter into this Pledge Agreement as an inducement to Parent and Merger Sub to enter into the Agreement. NOW, THEREFORE, in consideration of the promises, and of the covenants, representations, warranties, and agreements contained herein, the parties hereto further agree as follows. SECTION 1. CERTAIN DEFINITIONS 1.1 Capitalized terms used herein but not defined herein shall have the meaning ascribed to them in the Agreement. SECTION 2. REPRESENTATIONS AND WARRANTIES 2.1 Christopher A.

(b) This Pledge Agreement constitutes the legal, valid and binding obligation of such Pledgor, in accordance with the terms hereof, and the Pledgor has good and lawful right and authority to execute the pledge provided for herein and to pledge the number of issued and outstanding Shares set forth on Schedule I opposite such Pledgor's name. (c) As to each of such Pledgor's issued and outstanding Shares: (i) the Pledgor is the sole legal, record and beneficial owner thereof, and the Pledgor has good and marketable title thereto, (ii) each Share is validly issued, fully paid and non-assessable and the holder thereof is not and will not be subject to any personal liability as such holder, (iii) each Share is and will remain free and clear of all security interests, pledges, liens or other encumbrances, and restrictions on the transfer and assignment thereof, except pursuant to this Pledge Agreement, the Voting Agreement, and applicable securities laws, and this Pledge Agreement is sufficient to convey to Parent a valid, first priority, perfected and enforceable security interest in, and lien on, any Collateral (as defined below) delivered to Parent hereunder, (iv) any consent, approval or authorization of or designation or filing with any governmental authority on the part of the Pledgor which is required in connection with the pledge and security interest granted under this Pledge Agreement has been obtained or effected, (v) there are no outstanding options, warrants or other requirements with respect to the Shares being pledged, and (vi) no interest of any kind in the Shares being pledged will be sold or otherwise transferred in any way to anyone prior to the Effective Time or termination of the Merger Agreement. 2.4 So long as this Pledge Agreement is in effect, each Pledgor covenants that it: (a) shall defend that Pledgor's Collateral against the claims and demands of all other parties except the security interest created by this Pledge Agreement, shall keep that Pledgor's Collateral free from all options, pledges, liens, claims, mortgages, hypothecations, charges, security interests or 80 other encumbrances except restrictions on transfer imposed by applicable securities laws, the security interest created by this Pledge Agreement, any security interests or other encumbrances created by the Parent, and as provided under applicable securities laws, and shall not sell, transfer, assign, deliver, or otherwise dispose of, or grant any option with respect to any part of that Pledgor's Collateral or any interest therein without the prior written consent of the Parent; and (b) shall pay all taxes, assessments, and other charges of every nature which may be imposed, levied, or assessed against or with respect to that Pledgor's Collateral. SECTION 3. PLEDGE OF SHARES 3.1 To provide collateral security for any Cash Shortfall, and to provide security and collateral for the due performance and compliance by each Pledgor of its obligations under this Pledge Agreement, each Pledgor hereby grants to Parent a first priority continuing security interest in, and pledges to Parent, all of the Pledgor's right, title and interest in and to the number of issued and outstanding Shares set forth on Schedule I opposite such Pledgor's name (the Pledgor's "Pledged Shares"), and as security agrees to deliver the certificates representing ownership of the Pledgor's Pledged Shares, accompanied by stock powers duly executed in blank and undated by the Pledgor, to Parent within ten Business Days following the date of this Pledge Agreement. Each Pledgor's Pledged Shares, together with any and all other securities and moneys received by Parent as provided for or paid in connection with those Pledged Shares and all cash and non-cash proceeds thereof while this Pledge Agreement is in effect (sometimes referred to herein collectively as that Pledgor's "Collateral"), shall be held by Parent upon the terms and conditions set forth in this Pledge Agreement. 3.2 Upon the delivery of a Pledgor's Pledged Shares to Parent in accordance with the preceding Section 3.1, Pledgor grants to Parent concerning that Pledgor's Pledged Shares an irrevocable proxy coupled with an interest and power of attorney pursuant to which proxy and power of attorney the Parent shall be entitled to complete appropriately the stock powers executed in blank by the Pledgor upon conveying the Pledged Shares to Parent and use these stock powers to exchange the certificates representing the Pledged Shares for the cash and/or Parent Common Stock payable in exchange for the Pledged Shares based on the Cash Election, Stock Election, or No Election made or deemed to be made by the Pledgor pursuant to the Agreement (hereinafter the "Election") and based on other provisions of the Agreement. Each Pledgor's Election shall be made pursuant to an Election Form to be delivered prior to the Closing by Pledgor. 3.3 Each Pledgor shall have the right to substitute $7.50 cash in lieu of any Pledged Share and $23.8125 in cash in lieu of any Parent Common Stock held by Parent as Pledgee under this Pledge Agreement (in which case, such cash shall form part of that Pledgor's Collateral hereunder). Upon delivery to the Parent of a wire transfer of such amount, Parent shall promptly, but in no event later than two Business Days, deliver any Pledged Shares or Parent Common Stock with respect to which $7.50 or $23.8125, as applicable, of cash collateral has been substituted as provided in this Section 3.3. 81 SECTION 4. VOTING OF PLEDGED SHARES 4.1 Each Pledgor shall be entitled to vote that Pledgor's Pledged Shares until the Effective Time, if the Merger is effected, or until the termination of this Pledge Agreement, if the Agreement is terminated, subject to the provisions of the Voting Agreement. SECTION 5. EFFECT OF TERMINATION OF THE AGREEMENT 5.1 If the Agreement is terminated, Parent shall as soon as practicable thereafter (but in no event later than three Business Days) deliver each Pledgor's Collateral to that Pledgor, and this Pledge Agreement shall terminate. If the Merger is effected, all the remaining provisions of this Pledge Agreement shall apply. SECTION 6. INITIALLY DETERMINED CONSIDERATION FOR PLEDGED SHARES 6.1 If the Cash Expenditure Certificate under Section 7.2(k) of the Agreement indicates that there is no Cash Shortfall as calculated under Section 7.2(l) of the Agreement, Parent as Pledgee shall as soon as practicable after the Effective Time exchange each Pledgor's Pledged Shares for the cash and/or Parent Common Stock payable in exchange for that Pledgor's Pledged Shares based on the Election made by that Pledgor under the Agreement and the terms of the Agreement. The total consideration payable in exchange for the aggregate number of the Pledgors' Pledged Shares based on the Pledgors' Elections and the terms of the Agreement shall be the "Total Merger Agreement Consideration," and the Pledged Shares shall be valued at $7.50 per Share in determining the dollar value of the Total Merger Agreement Consideration 82 6.2 If there is a Cash Shortfall as calculated on the Cash Expenditure Certificate, the total consideration initially payable in exchange for all the Pledged Shares (the "Total Initial Adjusted Consideration") shall be the Total Merger Agreement Consideration reduced on a dollar for dollar basis of the Cash Shortfall as calculated on the Cash Expenditure Certificate except that the reduction shall not exceed $5,000,000.00. The Pledged Shares shall be valued at $7.50 per Share in determining the dollar value of the Total Initial Adjusted Consideration. In such event, the consideration initially payable in exchange for each Pledgor's Pledged Shares (that Pledgor's "Initial Adjusted Consideration") shall be the applicable percentage set forth on Schedule I of the Total Initial Adjusted Consideration, and the Parent as Pledgee shall as soon as practicable after the Effective Time exchange each Pledgor's Pledged Shares for that Pledgor's Initial Adjusted Consideration. To the extent that, pursuant to the Election made by a Pledgor under the Agreement and the terms of the Agreement, Parent Common Stock would be payable in exchange for that Pledgor's Pledged Shares, Parent Common Stock, valued at $23.8125 per share, shall first be used to satisfy that Pledgor's Initial Adjusted Consideration; provided, that in accordance with the provisions of Section 4.2(e) of the Agreement, cash shall be paid instead of a fractional share of Parent Common Stock that would otherwise be payable in accordance with this sentence. Cash shall be used to satisfy any amount of a Pledgor's Initial Adjusted Consideration not satisfied by Parent Common Stock in accordance with the preceding sentence and pursuant to the terms of the Agreement. 6.3 After exchanging each Pledgor's Pledged Shares for the cash and/or Parent Common Stock payable in exchange for those Pledged Shares under Subsection 6.1 or Subsection 6.2 above, Parent shall thereafter hold such cash and/or Parent Common Stock as that Pledgor's Collateral subject to this Pledge Agreement. SECTION 7. VOTING AND DIVIDENDS ON PARENT COMMON STOCK HELD AS PART OF A PLEDGOR'S COLLATERAL After Parent has exchanged a Pledgor's Pledged Shares for cash and/or Parent Common Stock, the Pledgor shall be entitled to vote any Parent Common Stock received in the exchange until the termination of this Pledge Agreement; provided, that during such period, the Pledgor shall cast no vote that would violate or interfere with the performance of any of the terms of the Agreement or this Pledge Agreement. Any dividends paid on a Pledgor's Pledged Shares prior to termination of this Pledge Agreement shall be held as part of that Pledgor's Collateral. SECTION 8. FINALLY DETERMINED CONSIDERATION FOR PLEDGED SHARES 8.1 (a) Within forty-five (45) calendar days following the Closing Date, Parent may, or may cause an independent auditor selected by Parent ("Parent's Independent Auditor") to, audit the Surviving Corporation's books and records to determine whether the Cash Expenditure Amount and Cash Shortfall as shown in the Cash Expenditure Certificate was accurate, such determination to be set forth in a report (the "Post-Closing Audit Report"). If Parent or Parent's Independent Auditor determines that the Cash Expenditure Amount or Cash Shortfall as shown 83 on the Cash Expenditure Certificate was inaccurate, and that as a result there either was a Cash Shortfall although the Cash Expenditure Certificate did not indicate a Cash Shortfall or the Cash Shortfall was larger than indicated by the Cash Expenditure Certificate, Parent may within the above forty-five (45) calendar day period deliver a written notice to Pledgors setting forth the Cash Expenditure Amount and Cash Shortfall as determined by the Post-Closing Audit Report and stating that Parent proposes an adjustment in the consideration payable in exchange for the Pledged Shares, as determined under Subsection 6.1 or 6.2 above, based on the Post-Closing Audit Report (the "Notice of Proposed Adjustment"). Parent shall also deliver to Pledgors a copy of such Post-Closing Audit Report. If Parent does not deliver a Notice of Proposed Adjustment to Pledgor during the above forty-five (45) calendar day period, no adjustment will be made in the consideration payable in exchange for a Pledgor's Pledged Shares as determined under Subsection 6.1 or Subsection 6.2 above. (b) Pledgors (acting as a group) shall have nine (9) calendar days from receipt of the Notice of Proposed Adjustment to deliver to Parent a notice stating that the Pledgors dispute the determination of the Cash Expenditure Amount and/or the Cash Shortfall by the Parent or the Parent's Independent Auditor (a "Notice of Dispute"). During such nine (9) calendar day period, Parent shall cause the Surviving Corporation to give an independent auditor chosen collectively by the Pledgors (acting as a group) (the "Pledgors' Independent Auditor") access to the Surviving Corporation's books and records. Parent shall also give Pledgors' Independent Auditor reasonable access to the work papers of Parent's Independent Auditor, if any, that Parent's Independent Auditor is permitted to release with Parent's consent (which Parent reasonably will provide) pursuant to Parent's Independent Auditor's standard policies. If Parent has not received a Notice of Dispute within the above nine (9) calendar day period, the Cash Expenditure Amount as given in the Notice of Proposed Adjustment shall be the basis for an adjustment in the consideration payable in exchange for the Pledged Shares to be made in accordance with Subsection 8.2 below. (c) If Pledgors have delivered a Notice of Dispute to Parent within the above nine (9) calendar day period, an independent accounting firm mutually acceptable to Parent and Pledgors (the "Independent Accounting Firm") shall perform any required procedures on the Company's books and records, and shall review the Notice of Proposed Adjustment, the Notice of Dispute, and the work papers of Parent's and Pledgors' Independent Auditors, if any, that they are permitted to release with their respective clients' permission (which will be reasonably provided) pursuant to their standard policies, to determine independently solely whether the Cash Shortfall and Cash Expenditure Amount set forth in the Notice of Proposed Adjustment or in the Notice of Dispute most closely represent the Cash Expenditure Amount and Cash Shortfall determined pursuant to the Agreement. The Cash Expenditure Amount and Cash Shortfall as determined by the Independent Accounting Firm shall then be the basis for determining the amount, if any, of the adjustment in the compensation for the Pledged Shares and for making such adjustment. The Independent Accounting Firm shall give notice of such Cash Expenditure Amount and Cash Shortfall to Parent and Pledgors. The cost of such Independent Accounting Firm shall be borne equally by the Parent and the Pledgors. 8.2 If the determination of the Cash Shortfall that, under Subsection 8.1(b) or Subsection 8.1(c) above, is to be used to make any adjustment in the consideration payable in exchange for the Pledged Shares is larger than the Cash Shortfall, if any, shown in the Cash 84 Expenditure Certificate, the dollar value of the Total Merger Agreement Consideration shall be reduced, on a dollar for dollar basis, to a "Total Final Adjusted Consideration" as follows: -- if the Cash Expenditure Certificate did not indicate a Cash Shortfall, the Total Merger Agreement Consideration shall be reduced to the extent of the Cash Shortfall, if any, as determined under Subsection 8.1(b) or Subsection 8.1(c), or -- if the Cash Expenditure Certificate indicated a Cash Shortfall, the Total Merger Agreement Consideration shall be reduced by the sum of (x) the Cash Shortfall indicated on the Cash Expenditure Certificate plus (y) the excess of (i) the Cash Shortfall as determined under Subsection 8.1(b) or 8.1(c) above, over (ii) the Cash Shortfall as indicated by the Cash Expenditure Certificate, provided, that in neither case shall the dollar value of Total Final Adjusted Consideration be $5,000,000.00 less than the dollar value of the Total Merger Agreement Consideration. The consideration payable in exchange for each Pledgor's Pledged Shares (the "Pledgor's Final Adjusted Consideration") shall be the applicable percentage set forth on Schedule I multiplied by the Total Final Adjusted Consideration. 8.3 Within five (5) calendar days after completion of the procedure in Subsection 8.1 for determining whether there shall be any final adjustment in the consideration for the Pledged Shares, whether such procedure is completed pursuant to Subsection 8.1(a), Subsection 8.1(b), or Subsection 8.1(c), Parent shall take one of the following two actions depending on whether there is to be such an adjustment: (a) If no adjustment in the consideration for Pledged Shares is to be made pursuant to the preceding Subsection 8.2 and no adjustment in the consideration for Pledged Shares was made pursuant to Subsection 6.2 above, Parent shall deliver each Pledgor's entire then existing Collateral to that Pledgor. (b) If no adjustment in the consideration for Pledged Shares is to be made pursuant to the preceding Subsection 8.2 but an adjustment in the consideration for Pledged Shares was made pursuant to Subsection 6.2 above, Parent shall pay each Pledgor from that Pledgor's then existing Collateral that Pledgor's Initial Adjusted Consideration. Parent shall be entitled to retain any part of a Pledgor's then existing Collateral not payable to the Pledgor under the above provisions of this Subsection 8.3(b) as Parent's property no longer subject to this Pledge Agreement, and Pledgor shall no longer have any interest in or rights with respect to such property. (c) If an adjustment in the consideration for Pledged Shares is to be made pursuant to the preceding Subsection 8.2, Parent shall pay each Pledgor from that Pledgor's then existing Collateral that Pledgor's Final Adjusted Consideration. To the extent that Parent Common Stock was paid to Parent as Pledgee in exchange for that Pledgor's Pledged Shares in accordance with the provisions of Subsection 6.1 or Subsection 6.2 above, Parent Common Stock, valued at $23.8125 per share, shall first be used to satisfy that Pledgor's Final Adjusted Consideration; provided, that in accordance with the provisions of Section 4.2(e) of the Agreement cash shall be paid instead of a fractional share of Parent Common Stock that would otherwise be payable in accordance with this sentence. Cash shall be used to satisfy any amount of a Pledgor's Final 85 Adjusted Consideration not satisfied by Parent Common Stock in accordance with the preceding sentence. Any dividends paid on Parent Common Stock used to satisfy a Pledgor's Final Adjusted Consideration while such Parent Common Stock was held by Parent pursuant to this Pledge Agreement shall be delivered by Parent to Pledgor along with, and in addition to, such Pledgor's Final Adjusted Consideration. Parent shall be entitled to retain any part of a Pledgor's then existing Collateral not payable to the Pledgor under the above provisions of this Subsection 8.3(c) as Parent's property no longer subject to this Pledge Agreement, and Pledgor shall no longer have any interest in or rights with respect to such property. SECTION 9. TERMINATION OF AGREEMENT IF THE MERGER IS EFFECTED 9.1 If the Merger is effected, this Pledge Agreement shall terminate when each Pledgor has received the consideration that Pledgor is entitled to receive under Subsection 8.3(a), Subsection 8.3(b), or Subsection 8.3(c) and Parent has received any portion of the Pledgors' Collateral that Parent is entitled to under the provisions of Subsection 8.3(b) or Subsection 8.3(c). SECTION 10. MISCELLANEOUS AND GENERAL 10.1 Survival. This Section 10 and the representations and warranties by Pledgors in Section 2 and the remedies in the event of an incorrect representation or warranty by a Pledgor, shall survive the termination of this Pledge Agreement for a period of one year. All other representations, warranties, covenants and agreements in this Pledge Agreement shall not survive the termination of this Pledge Agreement. 10.2 Modification or Amendment. Subject to the provisions of the applicable law, at any time prior to the Effective Time, the parties hereto may modify or amend this Pledge Agreement, by written agreement executed and delivered by duly authorized officers of the respective parties. 10.3 Counterparts.

Crane 97 EXHIBIT F NON-COMPETITION AND NON-DISCLOSURE AGREEMENT This AGREEMENT dated this 3rd day of November, 1999 (the "Agreement"), is made and entered into by and between Christopher A. Crane ("Principal"), CoStar Group, Inc., a Delaware corporation ("Parent"), and its wholly-owned subsidiary Acq Sub, Inc., a Delaware corporation ("Merger Sub"). WHEREAS, Parent, Merger Sub, and COMPS.COM, Inc., a Delaware corporation ("Company"), have entered into an Agreement and Plan of Merger, dated November 3, 1999 (the "Merger Agreement") pursuant to which Company shall merge with and into Merger Sub and the separate corporate existence of Company shall cease; WHEREAS, Principal and Company have entered into an "Executive Employment Agreement," dated October 14, 1994, pursuant to which Principal is employed as President and Chief Executive Officer of Company; WHEREAS, it is mutually agreed between Principal, Company, and Merger Sub that Principal shall resign his employment as President and Chief Executive Officer of Company, said resignation to take effect as of the date that the Merger between Company and Merger Sub becomes effective (the "Merger Effective Date"); WHEREAS, it is also mutually agreed between Principal, Company, and Merger Sub that Principal shall be employed as an employee of Merger Sub for a period of one hundred eighty (180) calendar days following the Merger Effective Date, and Principal, Company, and Merger Sub have accordingly entered into a "Separation and Employment Agreement" dated November 3, 1999; WHEREAS, Principal has beneficial ownership of over twenty (20) percent of the common stock of Company, and will receive considerable financial benefit when the Merger becomes effective; WHEREAS, the Merger Agreement requires that Principal, Parent, and Merger Sub enter into this Agreement; NOW, THEREFORE, in consideration of the foregoing, and of the respective representations, warranties, covenants and agreements contained herein, the parties agree as follows (unless otherwise defined herein, capitalized terms used herein shall have the meanings given such terms in the Merger Agreement): 1. Effective Date. This Agreement shall take effect on the Merger Effective Date. 2. Non-Competition. In order to induce Parent and Merger Sub to enter into the Merger Agreement and to pay the valuable consideration required thereunder, to create a valuable 98 independent asset of Merger Sub, to preserve and protect the goodwill thereof, and to enhance the going concern value and earnings of Merger Sub in future years, Principal undertakes and agrees as follows: (a) Commencing on the Merger Effective Date and for a period of twenty-four (24) months after the Merger Effective Date (the "Term"), Principal shall not, within the parts of the United States where Company conducted business (the "Territory"), create, seek or accept employment or compensation of any kind or character from any enterprise, or person associated with such an enterprise, engaged or planning to engage, directly or indirectly, in any activity that is the same or similar to, or competitive with, any activity engaged in or proposed to be engaged in by Company on the Merger Effective Date; provided, however, that Principal may seek or accept such employment or compensation with the prior consent of Merger Sub, which consent may be conditioned or withheld by Merger Sub in its sole and absolute discretion. (b) During the Term, neither Principal nor any entity in which Principal may be not immaterially interested (as a principal, owner, partner, joint venturer, trustee, director, officer, employee, consultant, agent, shareholder, option holder, security holder, lender, creditor, guarantor, independent contractor, advisor, member, sales representative, or in any other capacity) shall, within the Territory, engage, directly or indirectly, in any activity that, directly or indirectly, is the same or similar to, or competitive with, any activity engaged in or proposed to be engaged in by Company on the Merger Effective Date; provided, however, that the foregoing shall not be deemed to prevent Principal from investing in securities if such class of securities in which the investment so made is listed on a national securities exchange or is issued by a company registered under Section 12(g) of the Securities Exchange Act of 1934, so long as such investment holdings do not, in the aggregate, constitute more than five percent (5%) of the voting power of any company's securities. (c) During the Term, Principal shall not, either in his individual capacity or as an agent for another: (i) hire or offer to hire any of Company's, Parent's or Merger Sub's officers, employees, or agents; (ii) entice away or in any other manner persuade or attempt to persuade any of Company's, Parent's or Merger Sub's officers, employees, or agents to discontinue their relationship with Company, Parent or Merger Sub; (iii) contract, solicit, divert, or attempt to divert from Parent or Merger Sub any business whatsoever by influencing or attempting to influence any customer of Company, Parent or Merger Sub with whom Company, Parent or Merger Sub has engaged in sales discussions prior to the termination of this Agreement; or (iv) call upon any person or entity as a prospective acquisition candidate for an entity other than Merger Sub or Parent who or that, during Principal's employment by Company or Principal's consulting relationship with Merger Sub was, to Principal's knowledge, either called upon by Company, Merger Sub or Parent as a prospective acquisition candidate or was the subject of an acquisition analysis conducted by Company, Merger Sub or Parent. Principal, to the extent lacking the knowledge described in the preceding sentence, shall immediately cease all contact with any prospective acquisition candidate upon being informed that Company, Merger Sub or Parent had called upon such candidate or made an acquisition analysis thereof. (d) The covenants set forth in this Section 2 shall be construed as a series of separate covenants covering their subject matter in each of the separate states where Company 99 conducted business and, except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant set forth above in this Section 2. To the extent that any such covenant shall be judicially unenforceable in any one or more of such states, such covenant shall not be affected with respect to each of the other states in the Territory. Each covenant with respect to each such state in the Territory shall be construed as severable and independent. (e) Parent, Merger Sub, and Principal acknowledge and recognize that these covenants not to compete are integral to the Merger Agreement, that without the protection of such covenants, Parent and Merger Sub would not have entered into the Merger Agreement, that the consideration paid by Parent and Merger Sub under the Merger Agreement bears no relationship to the damages Parent and Merger Sub may suffer in the event of any breach of the covenants, and that such covenants contain reasonable limitations as to time, geographical area and scope of activity to be restrained necessary to protect Parent's and Merger Sub's business interests. If this Section 2 shall for any reason be held excessively broad as to time, duration, geographical scope, activity or subject, it shall be enforceable to the extent compatible with then-applicable laws. (f) Principal agrees that all references to Parent in Sections 2 and 3 shall be deemed to refer to Parent, its subsidiaries and affiliates and that all references to Company in Sections 2 and 3 shall be deemed to refer to Company, its subsidiaries and affiliates. 3. Confidential Information. (a) The parties acknowledge and agree that: (i) The Company assets being merged into Merger Sub pursuant to the Merger Agreement include confidential and proprietary information of Company and, in the course of his employment for Merger Sub, Principal may develop and obtain access to confidential and proprietary information of Parent and Merger Sub (collectively, the "Confidential Information"), which Confidential Information shall include, without limitation, all of the following materials and information of Company, Parent, or Merger Sub (whether or not reduced to writing and whether or not patentable or protected by copyright): trade secrets, product specifications, proprietary software systems, sources of data, databases, know-how, formulae, inventions and ideas, designs, sketches, photographs, graphs, drawings, samples, selling and pricing information and procedures, research methodologies, customer lists, business and marketing plans, current and anticipated customer requirements, market studies, and internal financial statements. The parties hereto agree that the failure of any Confidential Information to be marked or otherwise labeled as confidential or proprietary information shall not affect its status as Confidential Information. (ii) The Confidential Information is confidential and proprietary, and the development and protection of the Confidential Information represents a substantial investment having a great economic and commercial value to Parent and Merger Sub. (iii) Parent and Merger Sub would be irreparably damaged if any of the 100 Confidential Information was disclosed to, or used or exploited on behalf of, any person other than Parent or Merger Sub. (b) Principal covenants and agrees that he shall not, at any time, directly or indirectly, use, exploit, or disclose to any person or entity, without the prior written consent of Parent or Merger Sub, any Confidential Information, except as expressly authorized by Parent or Merger Sub during the performance of Principal's duties for and with Merger Sub. Principal agrees that, given the nature of Merger Sub's and Parent's business and business plans there will never come a time when disclosure of the Confidential Information would not be seriously injurious to Merger Sub and Parent. (c) Notwithstanding the foregoing, Principal may use, exploit, or disclose Confidential Information, but only to the extent that such Confidential Information (i) is or becomes publicly known through no wrongful act of Principal; or (ii) is disclosed pursuant to the requirement of a governmental agency or a court of law or otherwise required by operation of law, provided that Principal gives Merger Sub and Parent prompt written notice of such requirement prior to disclosure. 4. Reasonableness of Restrictions. PRINCIPAL HAS CAREFULLY READ AND CONSIDERED THE PROVISIONS OF SECTIONS 2 AND 3 HEREOF AND, HAVING DONE SO, HEREBY AGREES THAT THE RESTRICTIONS SET FORTH IN SUCH SECTIONS ARE FAIR AND REASONABLE AND ARE REASONABLY REQUIRED FOR THE PROTECTION OF THE INTERESTS OF PARENT AND MERGER SUB. 5. Injunctive Relief. (a) Principal acknowledges and agrees that Parent and Merger Sub will suffer irreparable harm in the event that Principal breaches any of its obligations under this Agreement, and that monetary damages shall be inadequate to compensate Parent and Merger Sub for any such breach. Principal agrees that in the event of any breach or threatened breach by Principal of the provisions of this Agreement, Parent and Merger Sub, or either of them, shall be entitled to a temporary restraining order, preliminary injunction, and permanent injunction in order to prevent or restrain any such breach or threatened breach by Principal, or by any or all of Principal's agents, representatives or other persons directly or indirectly acting for, on behalf of, or with Principal. (b) Notwithstanding the provisions set forth in Section 5(a) above, or any other provision contained in this Agreement, the parties hereby agree that no remedy conferred by any of the specific provisions of this Agreement, including without limitation, this Section 5, is intended to be exclusive of any other remedy, and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by statute or otherwise. 101 6.

Specifically, but without limitation, we have made no inquiries of securities holders or employees of Parent or Merger Sub, other than certain officers of Parent and Merger Sub; and we have not searched the dockets of any courts or government agencies. This opinion letter relates solely to the General Corporation Law of the State of Delaware (the "DGCL") and the federal law of the United States, and we express no opinion with respect to the effect or application of any other laws including, without limitation, the laws of the State of California. Special rulings of authorities administering such laws or opinions of other counsel have not been sought or obtained. We have not examined the question of, and express no opinion as to, what law would govern the interpretation or enforcement of the Agreement. Based upon our examination of and reliance upon the foregoing and subject to the limitations, exceptions, qualifications and assumptions set forth below and except as set forth in the Agreement, we are of the opinion that, as of the date hereof: 1. Parent and Merger Sub are corporations that are duly incorporated, validly existing, and in good standing under the laws of the State of Delaware, and the Parent has the requisite corporate power and authority to own its properties and to conduct its business as such business is described in the Parent SEC Reports. Merger Sub has not conducted any business prior to the date of the Agreement and has no assets, liabilities, or obligations of any nature other than those incident to its formation and pursuant to the Agreement, the Merger, and the other transactions contemplated by the Agreement. 2. Parent and Merger Sub have the requisite corporate power and authority to execute, deliver, and perform the Agreement. The Agreement has been duly and validly authorized by each of Parent and Merger Sub, and duly executed and delivered by an authorized officer of each of Parent and Merger Sub. The Agreement constitutes a legal, valid, and binding obligation of the Parent and Merger Sub, enforceable by you in accordance with its terms. 3. The capitalization of Parent is as follows: The authorized capital stock of Parent consists of 30,000,000 shares of Parent Common Stock, of which "______" shares were, to our knowledge, outstanding as of the Closing Date, and 2,000,000 shares of Preferred Stock, par value $0.01 per share, of which "_________" shares were, to our knowledge, outstanding as 106 COMPS.COM, Inc. [Closing Date] Page 3 of the Closing Date. All of the outstanding shares of Parent Common Stock have been duly authorized and are validly issued, fully paid, and nonassessable.

To our knowledge, the execution and delivery of the Agreement by Parent and Merger Sub as of the Closing Date, and their respective performance of their obligations thereunder and compliance by Parent and Merger Sub with the terms of the Agreement, do not and will not violate any provision of any federal statute, rule or regulation applicable to Parent or Merger Sub, the DGCL or any provision of their respective certificates of incorporation, as currently in effect, or the bylaws of Parent or Merger Sub as currently in effect, and, to our knowledge, do not and will not conflict with or constitute a default under the provisions of any judgment, writ, decree or order, or the material provisions of any material agreement. 6. We are not aware that there is any action, proceeding or governmental investigation pending or overtly threatened in writing against Parent or Merger Sub, except as set forth in the Parent SEC Reports, which (a) questions the validity of the Agreement or the right of Parent or Merger Sub to enter into the Agreement or (b) would reasonably be expected to have a material adverse effect on their respective businesses or properties, if any, taken as a whole. 7. The shares of Parent Common Stock issuable pursuant to the Agreement are duly authorized, validly issued, fully paid, nonassessable and not issued in violation of any preemptive rights arising under the DGCL, the Parent Certificate or the Parent Bylaws. To our knowledge, the issuance of such shares will not violate any preemptive or similar rights arising under any Contract to which the Parent is a party or by which its assets are bound. Our opinions expressed above are specifically subject to the following limitations, exceptions, qualifications, and assumptions: 107 COMPS.COM, INC. [Closing Date] Page 4 A. We express no opinion as to the compliance or noncompliance of Parent or Merger Sub with applicable federal or state antifraud or antitrust statutes, laws, rules and regulations. B. We express no opinion concerning the past, present or future fair market value of any securities. C. We express no opinion as to your compliance with any Federal or state law relating to your legal or regulatory status or the nature of your business. D. With respect to our opinion in Paragraph 5, we have not conducted any special investigation of laws, and such opinions are limited to the DGCL and such United States laws as in our experience are of general application to transactions of the sort contemplated by the Agreement. Without limitation, such opinions do not extend to licenses, permits, approvals, etc. necessary for the conduct of Parent's or Merger Sub's business. Further, we express no opinion as to the effect of or compliance with any state or federal laws or regulations applicable to the transactions contemplated by the Agreement because of the nature of the business of any party thereto other than Parent or Merger Sub. In addition, with respect to our opinion in Paragraph 5, we have relied solely upon the representations of certain officers of Parent or Merger Sub regarding the existence of facts that may result in a material default, etc., and have conducted no special investigation of agreements of Parent or Merger Sub. We have made no analysis with respect to compliance of the Parent or Merger Sub with any financial ratios and the like set forth in any real property lease, equipment lease or other agreements to which the Parent or Merger Sub is a party, and we express no opinion on the effect of the consummation of the transactions covered by the Agreement on compliance of Parent or Merger Sub with such financial covenants. E. With respect to our opinion in Paragraphs 3 and 4 that the issued and outstanding shares of Common Stock of Parent and Merger Sub are fully paid, we have relied solely upon the representations concerning receipt by Parent or Merger Sub of consideration for such shares made to us in certificates executed by officers of Parent or Merger Sub. With respect to our opinion in Paragraph 3 as it relates to the valid issuance and the number of shares of outstanding Parent's Common Stock, the number of outstanding options to purchase the Parent's Common Stock and the existence of any other options, warrants, conversion privileges or other rights, we have relied solely on our review of corporate minutes and on written representations of the officers of Parent. F. We express no opinion as to limitations imposed by the DGCL, federal law or general equitable principles upon the specific enforceability of any of the remedies, covenants or other provisions of the Agreement and upon the availability of injunctive relief or other equitable remedies, regardless of whether enforcement of the Agreement is considered a proceeding in equity or at law. 108 COMPS.COM, Inc. [Closing Date] Page 5 G. We express no opinion as to the effect of Delaware court decisions, invoking statutes or principles of equity, which have held that certain covenants and provisions of agreements are unenforceable where (i) the breach of such covenants or provisions imposes restrictions or burdens upon a party, and it cannot be demonstrated that the enforcement of such restrictions or burdens is reasonably necessary for the protection of the other party, or (ii) the other party's enforcement of such covenants or provisions under the circumstances would violate the other party's implied covenant of good faith and fair dealing, or (iii) the breach of such covenants or provisions is not a material breach of a material covenant or provision. H. We express no opinion as to any law, (federal or state) or equitable principle which provides that a court may refuse to enforce, or may limit the application of, a contract or any clause thereof which the court finds to have been unconscionable at the time it was made or contrary to public policy. I. We express no opinion as to the enforceability under certain circumstances of provisions expressly or by implication waiving broadly or vaguely stated rights, unknown future rights, or defenses to obligations or rights granted by law, when such waivers are against public policy or prohibited by law. J. We express no opinion as to the enforceability under certain circumstances of provisions to the effect that rights or remedies are not exclusive, that rights or remedies may be exercised without notice, that every right or remedy is cumulative and may be exercised in addition to or with any other right or remedy, that election of a particular remedy or remedies does not preclude recourse to one or more remedies, or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy. K. We express no opinion as to the validity, binding effect or enforceability of any provisions prohibiting waivers of any terms of the Agreement other than in writing, or prohibiting oral modifications thereof or modification by course of dealing. This opinion letter is rendered as of the date first written above solely for your benefit in connection with the Agreement and may not be delivered to, quoted or relied upon by any person other than you, or for any other purpose, without our prior written consent. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to Parent or Merger Sub. We assume no obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which may alter, affect or modify the opinions expressed herein.
