If required, the Company will file the Prospectus and any amendments or supplements thereto with the Commission in the manner and within the time period required by Rule 424(b). During any time when a prospectus relating to the Shares is required to be delivered under the Act, the Company will comply with all requirements imposed upon it by the Act and the -18- Rules and Regulations to the extent necessary to permit the continuance of sales of or dealings in the Shares in accordance with the provisions hereof and of the Prospectus, as then amended or supplemented. With respect to any registration statement, prospectus, amendment, or supplement to be filed with the Commission in connection with the Shares, the Company will provide a copy of each such document to the Representatives a reasonable time prior to the date such document is proposed to be filed with the Commission and will not file any such document without the consent of the Representatives. Any such registration statement, prospectus, amendment or supplement, when filed, will comply with the Act. In the event that the Registration Statement is effective at the time of execution of this Agreement, but the total number of Shares subject to this Agreement exceeds the number of Shares covered by the Registration Statement, the Company will promptly file with the Commission on the date hereof a registration statement pursuant to Rule 462(b) in accordance with the requirements of such Rule and will make payment of the filing fee therefor in accordance with the requirements of Rule 111(b) under the Act.

The Company will use its best efforts to prevent the issuance of any stop order by the Commission, and if at any time the Commission shall issue any stop order, the Company will use its best efforts to obtain the withdrawal of such stop order at the earliest possible moment. (c) The Company will cooperate with the Representatives, their counsel and the Underwriters in qualifying or registering the Shares for sale, or obtaining an exemption therefrom, under the blue sky laws of such jurisdictions as the Representatives shall designate, and will continue such qualifications or registrations or exemptions in effect so long as reasonably requested by the Representatives to effect the distribution of the Shares.

If, at any time when a prospectus relating to the Shares is required to be delivered under the Act, any event occurs as a result of which the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, or if it becomes necessary at any time to amend or supplement the Prospectus to comply with the Act or the Rules and Regulations, the Company promptly will so notify the Representatives and will prepare and file with the Commission an amendment to the Registration Statement or an amendment or supplement to the Prospectus which will correct such statement or omission or effect such compliance; each such amendment or supplement to be reasonably satisfactory to counsel to the Underwriters.

The Company will operate its business in such a manner and, pending application of the net proceeds of the offering for the purposes and in the manner set forth under the caption "Use of Proceeds" in the Prospectus, will invest such net proceeds in such securities so as not to become an "investment company" as such term is defined under the Investment Company Act. (m) The Company will timely file all such reports, forms or other documents as may be required from time to time, under the Act, the Rules and Regulations, the Exchange Act and the rules and regulations thereunder, and all such reports, forms and documents so filed will comply as to form and substance with the applicable requirements under the Act, the Rules and Regulations, the Exchange Act and the rules and regulations thereunder which may from time to time be applicable to the Company.

(l) No order suspending the sale of the Shares in any jurisdiction designated by you pursuant to Section 6(c) hereof has been issued on or prior to the Closing Date or any Option Closing Date, as the case may be, and no proceedings for that purpose have been instituted or, to the best knowledge of such persons or that of the Company, have been or are contemplated. -26- (m) The Representatives shall have received from each person who is a director or officer of the Company, each stockholder, and each other person or group of persons who has the right to acquire more than five percent (5%) or more of the outstanding shares of Stock, assuming exercise of currently exercisable stock options on a fully diluted basis, an agreement to the effect that such person will not, directly or indirectly, without the prior written consent of the Representatives, on behalf of the Underwriters, offer, sell, contract to sell, grant any option to purchase, pledge or otherwise dispose (or announce any offer, sale, contract of sale, grant of an option to purchase, pledge or other disposition) of any shares of Common Stock or any securities convertible into, or exchangeable or exercisable for, shares of Common Stock for a period of 180 calendar days after the date of the Prospectus.

All approvals, consents and filings required or necessary to effectuate the IDP Acquisition shall have been obtained. The IDP Acquisition shall be effective on the Closing Date. (s) FBW shall have received $300,000 from the Company in satisfaction of the advisory fee owed to FBW pursuant to the letter agreement between the Company and FBW dated January 15, 1998, $50,000 of which has been received as of the date of this Agreement. -27- (t) The Company shall have furnished the Underwriters with such further opinions, letters, certificates or documents as the Representatives or counsel for the Underwriters may reasonably request. All opinions, certificates, letters and documents to be furnished by the Company will comply with the provisions hereof only if they are reasonably satisfactory in all material respects to the Underwriters and to counsel for the Underwriters. The Company shall furnish the Underwriters with manually signed or conformed copies of such opinions, certificates, letters and documents in such quantities as you reasonably request. The certificates delivered under this Section 8 shall constitute representations, warranties and agreements of the Company as to all matters set forth therein as fully and effectively as if such matters had been set forth in Section 2 of this Agreement. If any condition to the Underwriters' obligations hereunder to be satisfied prior to or at either the Closing Date or any Option Closing Date is not so satisfied, this Agreement, at the Representatives' election, will terminate upon notification to the Company without liability on the part of any Underwriter (including the Representatives) or the Company, except for the expenses to be paid by the Company pursuant to Section 7 hereof and except to the extent provided in Section 9 hereof. SECTION 9. INDEMNIFICATION. (a) The Company agrees to indemnify and hold harmless each Underwriter, and its officers, directors, partners, employees, agents and counsel, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages, liabilities or expenses whatsoever (which shall include, for all purposes of this Section 9, but not be limited to, attorneys' fees and any and all fees and expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever and any and all amounts paid in settlement), joint or several (and actions in respect thereof), to which such Underwriter, officer, director, partner, employee, agent, counsel or controlling person may become subject, under the Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages, liabilities, expenses or actions arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or the Prospectus or any Preliminary Prospectus, or any amendment or supplement thereto, or any blue sky application or other document executed by the Company specifically for the purposes of qualifying, or based upon written information furnished by the Company in any state or other jurisdiction in order to qualify, any or all of the Shares under the securities or blue sky laws thereof (any such application, document or information being hereinafter called a "Blue Sky Application"), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not -28- misleading, and will reimburse, as incurred, reasonable expenses of such Underwriter, partner, employee, agent, counsel or controlling person in connection with investigating, defending or appearing as a third party witness in connection with any such loss, claim, damage, liability, expense or action; PROVIDED, HOWEVER, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability, expense or action arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any of such documents in reliance upon and in conformity with information furnished in writing to the Company on behalf of such Underwriter through the Representatives expressly for use therein, and PROVIDED, FURTHER, that such indemnity with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) from whom the person asserting any such loss, claim, damage, liability, expense or action purchased Shares which are the subject thereof to the extent that any such loss, claim, damage, liability or action (i) results from the fact that such Underwriter failed to send or give a copy of the Prospectus (as amended or supplemented) to such person at or prior to the confirmation of the sale of such Shares to such person in any case where such delivery is required by the Act and (ii) arises out of or is based upon an untrue statement or omission of a material fact contained in such Preliminary Prospectus that was corrected in the Prospectus (as amended and supplemented), unless such failure resulted from non-compliance by the Company with Section 6(h) hereof. The indemnity agreement in this paragraph (a) shall be in addition to any liability which the Company may otherwise have. (b) Each of the Underwriters agrees severally, but not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, claims, damages, liabilities or expenses whatsoever (which shall include, for all purposes of this Section 9, but not be limited to, attorneys' fees and any and all fees and expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever and any and all amounts paid in settlement), (and actions in respect thereof) to which the Company or any such director, officer, or controlling person may become subject, under the Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages, liabilities, expenses or actions arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or the Prospectus or any Preliminary Prospectus, or any amendment or supplement thereto or in any Blue Sky Application, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with information furnished in writing by that Underwriter through the Representatives to the Company expressly for use therein. The Company acknowledges that the statements with respect to the public -29- offering of the Shares set forth under the caption "Underwriting" and the stabilization legend in the Prospectus have been furnished by the Underwriters to the Company expressly for use therein and constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Prospectus. The indemnity agreement contained in this paragraph (b) shall be in addition to any liability which the Underwriters may otherwise have. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against one or more indemnifying parties under this Section 9, notify such indemnifying party or parties of the commencement thereof; but the failure so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under paragraph (a) or (b) of this Section 9 to the extent that the indemnifying party was not adversely affected by such omission. In case any such action is brought against an indemnified party and it notifies an indemnifying party or parties of the commencement thereof, the indemnifying party or parties against which a claim is to be made will be entitled to participate therein and, to the extent that it or they may wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; PROVIDED, HOWEVER, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party has reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and otherwise to participate in the defense of such action on behalf of such indemnified party or parties. In no event shall the indemnifying party be liable for fees and expenses of more than one counsel separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdictions arising out of the same general allegations or circumstances. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses (other than the reasonable costs of investigation) subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party has employed such counsel in connection with the assumption of such different or additional legal defenses in accordance with the proviso to the immediately preceding sentence, (ii) the indemnifying party has not employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, or (iii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. (d) If the indemnification provided for in this Section 9 is unavailable or insufficient to hold harmless an indemnified party under paragraph (a) or (b) above in -30- respect of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (or actions in respect thereof) (i) in such proportion as is appropriate to reflect the relative benefits received by each of the contributing parties, on the one hand, and the party to be indemnified, on the other hand, from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of each of the contributing parties, on the one hand, and the party to be indemnified, on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. In any case where the Company is a contributing party and the Underwriters are the indemnified party, the relative benefits received by the Company on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares (before deducting expenses) bear to the total underwriting discounts received by the Underwriters hereunder, in each case as set forth in the table on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to above in this paragraph (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this paragraph (d), the Underwriters shall not be required to contribute any amount in excess of the underwriting discounts applicable to the Shares purchased by the Underwriters hereunder. The Underwriters' obligations to contribute pursuant to this paragraph (d) are several in proportion to their respective underwriting obligations, and not joint. No person guilty of fraudulent misrepresentations (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), (i) each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter and (ii) each director of the Company, each officer of the Company who has signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect to which claim for contribution may be made against another party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties shall not -31- relieve the party or parties from whom contribution may be sought from any other obligation (x) it or they may have hereunder or otherwise than under this paragraph (d) or (y) to the extent that such party or parties were not adversely affected by such omission. The contribution agreement set forth above shall be in addition to any liabilities which any indemnifying party may otherwise have. SECTION 10. REPRESENTATIONS, ETC. TO SURVIVE DELIVERY. The respective representations, warranties, agreements, covenants, indemnities and statements of, and on behalf of, the Company and its officers and the Underwriters, respectively, set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters, and will survive delivery of and payment for the Shares. Any successors to the Underwriters shall be entitled to the indemnity, contribution and reimbursement agreements contained in this Agreement. SECTION 11. EFFECTIVE DATE AND TERMINATION. (a) This Agreement shall become effective at 9:00 a.m., Washington, D.C. time, on the first business day following the date hereof, or at such earlier time after the Registration Statement becomes effective as the Representatives, in its sole discretion, shall release the Shares for the sale to the public, unless prior to such time the Representatives shall have received written notice from the Company that it elects that this Agreement shall not become effective, or the Representatives shall have given written notice to the Company that the Representatives on behalf of the Underwriters elect that this Agreement shall not become effective; PROVIDED, HOWEVER, that the provisions of this Section 11 and of Section 7 and Section 9 hereof shall at all times be effective. For purposes of this Section 11(a), the Shares to be purchased hereunder shall be deemed to have been so released upon the earlier of notification by the Representatives to securities dealers releasing such Shares for offering or the release by the Representatives for publication of the first newspaper advertisement which is subsequently published relating to the Shares. (b) This Agreement (except for the provisions of Sections 7 and 9 hereof) may be terminated by the Representatives by notice to the Company in the event that the Company has failed to comply in any respect with any of the provisions of this Agreement required on its part to be performed at or prior to the Closing Date or any Option Closing Date, as the case may be, or if any of the representations or warranties of the Company are not accurate in any respect or if the covenants, agreements or conditions of, or applicable to, the Company herein contained have not been complied with in any respect or satisfied within the time specified on the Closing Date or any Option Closing Date, as the case may be, or if prior to the Closing Date or any such Option Closing Date: (i) the Company shall have sustained a loss by strike, fire, flood, accident or other calamity of such a character as to interfere materially with the -32- conduct of the business and operations of the Company regardless of whether or not such loss was insured; (ii) trading in the Stock shall have been suspended by the Commission or the NNM or trading in securities generally on the New York Stock Exchange or the NNM shall have been suspended or a material limitation on such trading shall have been imposed or minimum or maximum prices shall have been established on either such exchange or market; (iii) a banking moratorium shall have been declared by New York or United States authorities; (iv) there shall have been an outbreak or escalation of hostilities between the United States and any foreign power or an outbreak or escalation of any other insurrection or armed conflict involving the United States; (v) there shall have been commenced any action, suit or proceeding at law or in equity against the Company, or by any federal, state or other commission, board or agency, wherein any unfavorable decision would materially adversely affect the business, properties or financial condition of the Company; (vi) there shall have occurred any material adverse market conditions, of which the Representatives shall be the sole judge; (vii) Company's independent public accountants shall have imposed qualifications in certifying to, or its attorneys in opining upon, material items including, without limitation, information in the footnotes to the financial statements or matters incident to the issuance and sale of the Shares, corporate proceedings or other subjects; or (viii) there shall have been a material adverse change in (i) general economic, political or financial conditions or (ii) the present or prospective business or condition (financial or other) of the Company that, in each case, in the Representatives judgment makes it impracticable or inadvisable to make or consummate the public offering, sale or delivery of the Company's Shares on the terms and in the manner contemplated in the Prospectus and the Registration Statement. (c) Termination of this Agreement under this Section 11 or Section 12 after the Firm Shares have been purchased by the Underwriters hereunder shall be applicable only to the Optional Shares. Termination of this Agreement shall be without liability of any party to any other party other than as provided in Sections 7 and 9 hereof. -33- SECTION 12. SUBSTITUTION OF UNDERWRITERS. If one or more of the Underwriters shall fail or refuse (otherwise than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 8 or 11 hereof) to purchase and pay for (a) in the case of the Closing Date, the number of Firm Shares agreed to be purchased by such Underwriter or Underwriters upon tender to the Representatives such Firm Shares in accordance with the terms hereof or (b) in the case of any Option Closing Date, the number of Optional Shares agreed to be purchased by such Underwriter or Underwriters upon tender to the Representatives of such Optional Shares in accordance with the terms hereof, and the number of such Shares shall not exceed ten percent (10%) of the Firm Shares or Optional Shares required to be purchased on the Closing Date or such Option Closing Date, as the case may be, then, each of the non-defaulting Underwriters shall purchase and pay for (in addition to the number of such Shares which it has severally agreed to purchase hereunder) its proportionate share (based on the monetary obligations of the several Underwriters hereunder on account of the purchase of Firm Shares, excluding the Firm Shares allocable to the defaulting Underwriter or Underwriters) which the defaulting Underwriter or Underwriters shall have so failed or refused to purchase on such Closing Date or Option Closing Date, as the case may be. In such case, the Representatives, on behalf of the Underwriters, shall have the right to postpone the Closing Date or the Option Closing Date, as the case may be, to a date not exceeding seven (7) full business days after the date originally fixed as such Closing Date or the Option Closing Date, as the case may be, pursuant to the terms hereof in order that any necessary changes in the Registration Statement, the Prospectus or any other documents or arrangements may be made. If one or more of the Underwriters shall fail or refuse (otherwise than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 8 or 11 hereof) to purchase and pay for (a) in the case of the Closing Date, the number of Firm Shares agreed to be purchased by such Underwriter or Underwriters upon tender to you of such Firm Shares in accordance with the terms hereof or (b) in the case of the Option Closing Date, the number of Optional Shares agreed to be purchased by such Underwriter or Underwriters upon tender to you of such Optional Shares in accordance with the terms hereof, and the number of such Shares shall exceed ten percent (10%) of the Firm Shares or Optional Shares required to be purchased by all the Underwriters on the Closing Date or the Option Closing Date, as the case may be, then (unless within forty-eight (48) hours after such default arrangements to your satisfaction shall have been made for the purchase of the defaulted Shares by an Underwriter or Underwriters) and subject to the provisions of Section 11(b) hereof, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or on the part of the Company except as otherwise provided in Sections 7 and 9 hereof. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this paragraph. Nothing in this Section 12, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. -34- SECTION 13.
