(the “Subordination Agreement”). Buyer will make all payments when due under the Note to the full extent allowed by the Subordination Agreement.

2.3 Earn-Out Payments.

(a) In addition to the Closing Purchase Price Distribution, Sellers shall be eligible to receive earn-out payments (“Earn-Out Payments”), upon achievement of Adjusted EBITDA as follows (it being understood that the aggregate Earn-Out Payment paid to Sellers pursuant to this Agreement shall not exceed $1,400,000 (the “Maximum Amount”) under any circumstances):

(i) If Adjusted EBITDA of the Business equals or exceeds $2,000,000 (the “Year 1 Adjusted EBITDA Target”) during the period beginning on Buyer’s 2015 fiscal year (approximately January 1, 2015) and ending on the last day of Buyer’s 2015 fiscal year (approximately December 31, 2015) (such period, “Year 1”), the Earn-Out Payment for Year 1 will be $560,000.

(ii) If Adjusted EBITDA of the Business equals or exceeds $3,000,000 (the “Year 2 Adjusted EBITDA Target”) during the period beginning on the first day of Buyer’s 2016 fiscal year and ending on last day of Buyer’s 2016 fiscal year (such period, “Year 2”), the Earn-Out Payment for Year 2 will $840,000. In the event that (y) the Business does not achieve the Year 1 Adjusted EBITDA Target, and/or the Year 2 Adjusted EBITDA Target, and (z) less than the Maximum Amount has been paid pursuant to Sections 1.1(a)(i), and (ii), if the cumulative Adjusted EBITDA for Year 1 and Year 2 equals or exceeds $5,000,000, an Earn-Out Payment shall be made after Year 2 equal to the lesser of (1) twenty-eight percent (28%) of the actual cumulative Adjusted EBITDA for Year 1 and Year 2 minus any Earn-Out Payment(s) previously received pursuant to Sections 1.1(a)(i) and 1.1(a)(ii), and (2) the Maximum Amount minus any Earn-Out Payment(s) previously received pursuant to Sections 1.1(a)(i) and 1.1(a)(ii), in all cases subject to the Earn-Out Claw Back. For avoidance of doubt, the actual Adjusted EBITDA for each of Year 1 and Year 2, including any negative amounts, shall be used in calculating the cumulative Adjusted EBITDA for Year 1 and Year 2.

(iii) If any Earn-Out Payments are made by Buyer to Sellers and it is subsequently determined that the Earn-Out Payments exceeded 28% of the total of the Year 1 Adjusted EBITDA Target and Year 2 Adjusted EBITDA Target, Buyer shall be entitled to reimbursement of the excess payments (the “Earnout Claw Back”), as follows. If the cumulative Adjusted EBITDA for Year 1 and Year 2 is less than $2,500,000, then Sellers shall reimburse Buyer the entire amount of all previous Earn-Out Payments. If the cumulative Adjusted EBITDA for Year 1 and Year 2 is more than $2,500,000, but less than $5,000,000, then Buyer shall pay Sellers the difference between the amount of the Earn-Out Payments previously paid to Buyer and 28% of the total of the Year 1 Adjusted EBITDA Target and Year 2 Adjusted EBITDA Target. No other claw back of any Earn-Out Payments will be made by Seller, except pursuant to this Section 1.1(a)(iii).

(iv) The Business shall utilize WGI’s corporate services with such corporate overhead expenses included in the calculation of Adjusted EBITDA. The Business shall be charged three percent (3%) of the gross revenue generated by the Business, which will be deducted prior to calculating the Adjusted EBITDA.

(b) As promptly as practicable after the end of each of Year 1 and Year 2 (but no later than one hundred and five (105) days after the last day of each fiscal year), Buyer shall deliver to Sellers a statement setting forth Buyer’s good faith calculation of the Adjusted EBITDA for such year and the cumulative Adjusted EBITDA for all prior years collectively (in each case, the “Adjusted EBITDA Statement”). Buyer shall, and shall cause its representatives (including outside auditors) to, make available to Seller, at Seller’s expense (without charge for Buyer’s or WGI’s costs) during normal business hours and following reasonable advance notice, the books, records, work papers, and personnel used or involved in the preparation of each Adjusted EBITDA Statement. If Sellers disagree with Buyer’s calculation any Adjusted EBITDA Statement delivered pursuant to this Section 1.1(a), Sellers may, within thirty (30) days after receipt of the Adjusted EBITDA Statement, deliver a notice to Buyer disagreeing with such calculation and setting forth the Seller’s calculation of such amount. Any such notice of disagreement shall specify in reasonable detail those items or amounts as to which Sellers disagree. If a notice of disagreement shall be duly delivered pursuant to Section 1.1(a), Sellers and Buyer shall, during the ten (10) days after such delivery, use their commercially reasonable efforts to reach agreement on the disputed items or amounts in order to determine, as may be required, the Adjusted EBITDA or cumulative Adjusted EBITDA, whichever is applicable, which amount shall not be more than the amount thereof shown in Seller’s calculation delivered pursuant to this Section 1.1(a). If following such 10-day period, Sellers and Buyer are unable to reach such agreement, they shall promptly thereafter (and in any event within twenty (20) days of the end of such 10-day period) cause a nationally recognized independent accounting firm mutually acceptable to them (the “Accounting Referee”) to review this Agreement and the disputed items or amounts for the purpose of calculating the Adjusted EBITDA (it being understood that in making such calculation, the Accounting Referee shall be functioning as an expert and not as an arbitrator). The Accounting Referee shall deliver to Sellers and Buyer as promptly as practicable (but in any case no later than thirty (30) days from the date of engagement of the Accounting Referee), a report setting forth such calculation. Such report shall be final and binding upon Sellers and Buyer. The cost of such review shall be borne equally by Sellers and Buyer. Buyer and Sellers shall, and shall cause their respective representatives to, and Buyer

shall cause the Business and its respective representatives (including outside auditors) to, cooperate and assist in the determination of the Adjusted EBITDA and in the conduct of the review set forth in this Section 1.1(a), including making available, to the extent necessary, books, records, work papers and personnel during normal business hours and following reasonable advance notice.

(c) Each Earn-Out Payment that is earned by Sellers in accordance with this Section 2.3 shall be paid by Buyer to Sellers within the later of: (i) one hundred twenty (120) days following the end of the applicable Year 1 or Year 2, and (ii) five (5) Business Days after the Adjusted EBITDA for the applicable Year 1 or Year 2 has been conclusively determined in accordance with Section 1.1(a) above. The remaining Earn-Out Payment shall be paid in cash by wire transfer of immediately available funds to the accounts Sellers have designated in writing to Buyer at least two (2) Business Days prior to such payment date.

2.4 Net Working Capital Adjustment.

(a) Sellers shall deliver to Buyer a statement setting forth Sellers’ good faith estimate of the Net Working Capital of Abacus as of 12:01 a.m. on the Closing Date (the “Estimated Net Working Capital”) (as illustrated on Schedule 2.3(a) hereto), which statement shall be prepared in accordance with GAAP applied on a consistent basis with Abacus’s pre-Closing methodologies used in preparation of monthly unaudited balance sheets, together with reasonably detailed supporting documentation for such calculation.

(b) As promptly as practicable after the Closing (but no later than sixty (60) days after the Closing Date), Sellers shall deliver to Buyer a statement setting forth Sellers’ good faith calculation of the Net Working Capital of Abacus as of the Closing Date (the “Closing Net Working Capital”). Such calculation shall be based upon an unaudited balance sheet prepared in accordance with GAAP (except for the exceptions to GAAP as set forth on Schedule 2.4(b)), applied on a consistent basis with Abacus’s pre-Closing methodologies in the preparation of monthly unaudited balance sheets (as illustrated on Schedule 1.1(a) hereto). If Buyer disagrees with Sellers’ calculation of the Closing Net Working Capital delivered pursuant to this Section 2.4(b), Buyer may, within twenty (20) days after receipt of the statement containing the Closing Net Working Capital, deliver a notice to Sellers disagreeing with such calculation and setting forth Buyer’s calculation of such amount. Any such notice of disagreement shall specify in reasonable detail those items or amounts as to which Buyer disagrees. If a notice of disagreement shall be duly delivered pursuant to this Section 2.4(b), Sellers and Buyer shall, during the twenty (20) days after such delivery, use their commercially reasonable efforts to reach agreement on the disputed items or amounts in order to determine, as may be required, the amount of the Closing Net Working Capital, which amount shall not be more than the amount thereof shown in Sellers’ calculation delivered pursuant to this Section 2.4(b) nor less than the amount thereof shown in Buyer’s calculation delivered pursuant to this Section 2.4(b). If during such period, Sellers and Buyer are unable to reach such agreement, they shall promptly thereafter cause an Accounting Referee to review this Agreement and the disputed items or amounts for the purpose of calculating the Closing Net Working Capital (it being understood that in making such calculation, the Accounting Referee shall be functioning as an expert and not as an arbitrator). The Accounting Referee shall deliver to Sellers and Buyer as promptly as practicable (but in any case no later than thirty (30) days from the date of engagement of the Accounting Referee), a report setting forth such calculation. Such

report shall be final and binding upon Sellers and Buyer. The cost of such review shall be borne equally by Sellers, on the one hand and Buyer, on the other hand. Buyer and Sellers shall, and shall cause their respective representatives to, and Buyer shall cause Abacus and its respective representatives (including outside auditors) to, cooperate and assist in the determination of the Closing Net Working Capital and in the conduct of the review set forth in this Section 2.4, including making available, to the extent necessary, books, records, work papers and personnel.

(c) If the Net Working Capital as conclusively determined as provided in Sections 2.4(b) (the “Final Net Working Capital”) is:

(1) Greater than $190,000 (the “Target Net Working Capital”), Buyer shall pay to Sellers, in the manner provided in Section 2.4(d), the amount equal to the difference between the Final Net Working Capital and the Target Net Working Capital; provided, however, that if the amount determined pursuant to this clause (d)(1) is a negative number, Sellers shall pay the absolute value of such amount to Buyer; or

(2) Less than the Target Net Working Capital, Sellers shall pay to Buyer, in the manner provided in Section 2.4(d), the amount equal to the difference between the Target Net Working Capital and the Final Net Working Capital,; provided, however, that if the amount determined pursuant to this clause (c)(2) is a negative number, Buyer shall pay the absolute value of such amount to Sellers; or

(d) Any payment pursuant to Section 2.4(c) shall be made at a mutually convenient time and place within five (5) Business Days after Final Net Working Capital has been determined pursuant to Section 2.4(b).

(e) The Aggregate Purchase Price shall be allocated between goodwill, intangible assets and other assets, which combined are the total purchase price. The parties shall report this Transaction on any Tax Returns in a consistent manner. In the event less than 80% of the total purchase price is allocated to the sum of goodwill plus intangible assets, less the allocation to covenant not-to-compete, Buyer shall reimburse Sellers for the difference in tax between ordinary income and capital gains, to the extent the portion allocable to goodwill plus intangibles, less the allocation to covenant not-to-compete, falls less than 80%.

Subject to the terms and conditions of this Agreement, the closing of the closing of the sale and purchase of the Capital Stock (the “Closing”) shall take place simultaneously with the execution of this Agreement on the date of this Agreement (the “Closing Date”) “virtually” at the offices of Xxxxxx & Xxxxxx, 0000 X.

ARTICLE VI
ADDITIONAL AGREEMENTS

6.1 Preservation of Records. Sellers shall provide all books and records of Abacus to Buyer on the Closing Date, provided, that Sellers shall be permitted to retain copies of such books and records, subject to the provisions of Section 6.2. Buyer agrees that it shall preserve and keep the books and records provided by Sellers to Buyer on the Closing Date for a period of one (1) year from the Closing Date; provided that, if any such books or records of Abacus relate to a Claim brought by a Seller Indemnified Party pursuant to Section 10.2 of this Agreement and such Claim is unresolved at the end of one (1) year from the date of this Agreement, then such books and records relating to such unresolved Claim may not be destroyed until the resolution of such Claim. During such one (1) year period, Buyer will give Sellers reasonable access during Buyer’s regular business hours upon reasonable advance notice and under reasonable circumstances, subject to restrictions under applicable Law, to such books and records of Abacus transferred to Buyer to the extent necessary for the preparation of financial statements, regulatory filings or Tax Returns of Sellers or their Affiliates in respect of periods ending on or prior to Closing, or in connection with any insurance claims, legal proceedings, Tax audits or governmental investigations or in order to enable Sellers to comply with their respective obligations under this Agreement and each other agreement, document or instrument contemplated hereby and thereby. Sellers shall be entitled, at their sole cost and expense, to make copies of the books and records to which they are entitled to access pursuant to this Section 6.1.

6.2 Cooperation With Respect to Financial Statements. Sellers agree to cooperate with, and provide reasonable assistance to, Buyer, including providing and consenting to any required disclosure, in connection with any filings, registration statements or reports of Buyer or any of its Affiliates under the Securities Act or the Exchange Act, and any rules and regulations promulgated thereunder. At Buyer’s request, such cooperation and assistance shall include, but

not be limited to, making available such financial information with respect to Abacus as may be reasonably required in connection with such filing, registration statement or report (to the extent such financial information is available to Sellers), including using commercially reasonable efforts to facilitate Buyer’s access to the independent accountants that issued the audit reports for Abacus’s Financial Statements and using commercially reasonable efforts to obtain the consent of such independent accountants for the filing of their audit report(s) with respect to the Financial Statements in any filings, registration statements or reports of Buyer or any of its Affiliates under the Securities Act or the Exchange Act and any rules and regulations promulgated thereunder. The cost of preparation of any such required financial information and consents shall be borne by Buyer.

6.3 Regulatory and Other Authorizations; Notices and Consents.

(a) Sellers and Abacus shall use their commercially reasonable efforts to give all notices and obtain all consents set forth on Schedules 3.4 and 4.4. Buyer shall cooperate and use all commercially reasonable efforts to assist Sellers in giving such notices and obtaining such consents; provided, however, that Buyer shall not have any obligation to give any guarantee or other consideration of any nature in connection with any such notice or consent or to consent to any change in the terms of any agreement or arrangement.

(b) Sellers and Buyer agree that, in the event any Order or Approval necessary to preserve any material right or benefit of the Business or Abacus under any Contract to which Abacus is a party is not obtained prior to the Closing, Sellers will, subsequent to the Closing, use their commercially reasonable efforts to cooperate with Buyer, to the extent reasonably necessary, at Buyer’s sole cost and expense, to attempt to obtain such Order or Approval as promptly thereafter as practicable; provided, however, that none of Sellers shall have any obligation to give any guarantee or other consideration of any nature in connection with any such Approval or Order.

6.4 Non-Competition; Non-Solicitation.

(a) Restrictions on Competitive Activities. Each Seller agrees that, after the Closing, Buyer, Abacus shall be entitled to the goodwill and going concern value of the Business and to protect and preserve the same to the maximum extent permitted by Law. Each Seller also acknowledges that his management contributions to the Business have been uniquely valuable and involve proprietary information that would be competitively unfair to make available to any competitor of Abacus. For these and other reasons and as an inducement to Buyer to enter into this Agreement, each Seller agrees that (x) for a period of five (5) years after the Closing Date (the “Restricted Period”), each Seller will not, directly or indirectly, for its own benefit or as agent for another carry on or participate in the ownership, management or control of, or the financing of, or be employed by, or consult for or otherwise render services or advice to, or allow its name or reputation to be used in or by, any other present or future business enterprise that competes with Buyer, Abacus in activities in which Abacus is engaged as of the Closing Date in any of the business territories in which Abacus is conducting business or is actively engaged in the pursuit of business or has conducted business within the prior five (5) years (the “Covered Area”).

(b) Restrictions on Soliciting Customers. Each Seller agrees that during the applicable Restricted Period, such Seller will not, directly or indirectly (i) induce, entice, or solicit any client or customer of Buyer or Abacus to terminate any contractual or business relationship with Buyer or Abacus, or (ii) in any other manner use any client or customer lists or client or customer leads, mail, telephone numbers, client preferences, or printed material of Buyer or Abacus to the detriment of Buyer or Abacus.

(c) Restrictions on Soliciting Employees. In addition to the foregoing covenants, to protect Buyer against any efforts by Sellers to cause employees of Abacus to terminate their employment, each Seller agrees that during the applicable Restricted Period, such Seller will not, directly or indirectly, (i) induce, entice or solicit any employee of Abacus to leave Abacus or to accept any other employment or position, or (ii) make referrals to, or otherwise assist, any other entity in hiring any such employee; provided, however, the foregoing shall not prohibit general solicitations of employment not specifically directed toward Continuing Employees or the hiring of such employees in response thereto, nor the hiring, employment or engagement of any Continuing Employee who presents himself or herself for employment without direct or indirect solicitation by any Seller or any Affiliate of any Seller.

(d) Exceptions. Nothing contained herein shall limit the right of any Seller as an investor to hold and make investments in securities of any corporation or limited partnership that is registered on a national securities exchange or admitted to trading privileges thereon or actively traded in a generally recognized over-the-counter market, provided such Seller’s equity interest therein does not exceed one percent (1.0%) of the outstanding shares or interests in such corporation or partnership.

(e) Special Remedies and Enforcement. Each Seller recognizes and agrees that a breach by such Seller of any of the covenants set forth in this Section 6.4 could cause irreparable harm to Buyer, that Buyer’s remedies at Law in the event of such breach would be inadequate, and that, accordingly, in the event of such breach a restraining order or injunction or both may be issued against such Seller, in addition to any other rights and remedies which are available to Buyer. If this Section 6.4 is more restrictive than permitted by the Laws of the jurisdiction in which Buyer seeks enforcement hereof, this Section 6.4 shall be limited to the extent required to permit enforcement under such Laws. The applicable Restricted Period shall also be extended by the same amount of time that any Seller is in breach of any provision of this Section 6.4.

(f) Severability. The parties intend that the covenants contained in Sections 6.4(a)-(c) hereof shall be construed as a series of separate covenants, one for each county, city, state, nation, and other political subdivision. Except for geographic coverage, each such separate covenant shall be deemed otherwise identical in terms. If, in any judicial proceeding, a court shall refuse to enforce any of such separate covenants (or any part thereof), then such unenforceable covenant (or such part) shall be deemed eliminated from this Section 6.4 for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced by such court. It is the intent of the parties that the covenants set forth in this Agreement be enforced to the maximum degree permitted by applicable Law.

(g) Representations of Sellers. Each Seller represents that: (i) he is familiar with the covenants set forth in this Agreement; (ii) he is fully aware of his obligations under this Agreement, including the length of time, scope and geographic coverage of these covenants; (iii) he is receiving specific, bargained-for consideration for his covenants not to compete and not to solicit; and (iv) execution of this Agreement, and performance of such Seller’s obligations under this Section 6.4, will not conflict with, or result in a violation or breach of, any other agreement to which the Seller is a party or any judgment, order or decree to which the Seller is subject.

(h) Reasonableness of Terms. Each Seller acknowledges that the length, scope of activity and geographic coverage to which the restrictions imposed in Sections 6.4(a)-(c) hereof shall apply are fair and reasonable and are reasonably required for the protection of Buyer and Abacus, including but not limited to protecting Abacus’s confidential, proprietary and trade secret information, the stable workforce maintained by Abacus, the relationships Abacus maintain with their customers, and the goodwill in Abacus acquired by Buyer. Each Seller further acknowledges that Abacus currently does business, is actively engaged in the pursuit of business or has conducted business within the prior five (5) years in the Covered Area.

6.5 Credit Agreement. Buyer and WGI agree to notify Sellers in writing within five (5) business of the occurrence of a Default or Event of Default under the Credit Agreement.

6.6 Taking of Necessary Action; Further Action. If, at any time after the Closing Date, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest Buyer with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Abacus, the officers and directors of Buyer are fully authorized in the name of Buyer or otherwise to take, and will take, all such actions at Buyer’s expense.

ARTICLE VII
EMPLOYEE MATTERS

7.1 Health and Benefit Plans.

(a) Within ten (10) Business Days following the Closing Date, the Continuing Employees as listed on Schedule 7.1 (provided such Continuing Employees are then employed by Buyer or Company) shall be covered by the employee benefit plans, programs, and policies established or maintained by Buyer applicable to similarly situated employees of Buyer (the “Buyer’s Plans”). Until the Continuing Employees have been transitioned to Buyer’s Plans, Buyer shall cause Abacus to maintain the employee benefit plans, programs and policies of Abacus existing on the Closing Date for the benefit of the Continuing Employees (the “Company’s Plans”). After the transition from Abacus’s Plans to Buyer’s Plans, Buyer agrees to maintain availability of coverage under Buyer’s Plans for Continuing Employees (so long as such Continuing Employee is employed by Buyer or Abacus) on the same basis and terms and conditions as for similarly situated employees of Buyer. Subject to the immediately preceding sentence, nothing contained in this Section 7.1 shall obligate or commit Buyer to continue Buyer’s Plans after the Closing Date or to maintain in effect any such plan or any level or type of benefits.

(b) Buyer shall cause each group health plan of Buyer or, with respect to an insured plan, use its commercially reasonable efforts to cause the insurer, to waive any pre-existing condition exclusions thereunder with respect to the Continuing Employees and their covered beneficiaries to the extent that such Continuing Employees are enrolled in the applicable group health plan of Abacus as of the Closing Date.

(c) For purposes of this Article VII, Continuing Employees shall receive credit for purposes of eligibility to participate and for vesting and benefit accruals under Buyer’s employee benefit plans, programs and policies for service accrued or deemed accrued prior to the Closing Date with Abacus; provided, however, that such prior service credit shall not operate to duplicate any benefit or the funding of any such benefit.

7.2 Mutual Cooperation. Sellers and Buyer agree, in a complete, diligent and timely manner, to exchange such employee census, actuarial or other data as shall be reasonably necessary to calculate benefits under any plan and to take any and all actions as shall be reasonably necessary or advisable to effect the provisions of this Article VII.

7.3 Third-Party Claims. Nothing in this Agreement is intended, or shall be construed, to confer upon any Person, other than the parties hereto and their successors and permitted assigns, any rights or remedies by reason of this Article VII.

ARTICLE VIII
TAX MATTERS

8.1 Returns and Payments. Following the Closing, Sellers shall cause Abacus to file, on a basis consistent with past practice (except as required by applicable Law), any and all Tax Returns for Pre-Closing Tax Periods (other than Straddle Periods), provided that Sellers will supply a copy such Tax Returns to Buyer ten (10) days prior to the due date for filing for the review and consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed.

8.2 Allocation of Taxes.

(a) Sellers shall be responsible for the payment of all Taxes of Abacus attributable to any Pre-Closing Tax Period and Buyer, subsequent to the Closing, shall be responsible for the payment of all Taxes with respect to Abacus attributable to any Post-Closing Tax Period.

Any credits relating to a Straddle Period shall be taken into account as though the relevant Tax period ended on the Closing Date.

8.3 Section 338(h)(10) Elections.

(a) The Sellers and the Buyer shall make a timely, effective, and irrevocable election under Section 338(h)(10) of the Code and under any comparable statutes in any other jurisdiction with respect to Abacus (collectively, the “Section 338(h)(10) Elections”) and shall file such Section 338(h)(10) Elections in accordance with applicable regulations. The Sellers and the Buyer shall cooperate in all respects for the purpose of effectuating the Section 338(h)(10) Elections, including the execution and filing of any required Tax Returns and the grant of consent to the Section 338(h)(10) Elections by the Sellers. Without limiting the foregoing, the Buyer and the Sellers shall each execute a Form 8023 with respect to Abacus at the Closing, which forms shall be timely filed by the Buyer. Sellers shall be responsible for all Taxes imposed on Abacus, or any Seller as a result of making the Section 338(h)(10) Elections.

(b) Within 120 days after the Closing Date, the Sellers shall deliver to the Buyer an allocation of the Aggregate Deemed Sales Price (as such term is defined in Treasury Regulation § 1.338-4) among the assets of Abacus in accordance with Treasury Regulations §§ 1.338-6 and 1.338-7 (the “Allocation Statement”). The allocation of the Aggregate Deemed Sales Price shall be in accordance with the fair market value of the acquired assets as provided in Section 1060 of the Code. The Buyer shall have the right to review the Allocation Statement. Within forty-five (45) days after the Buyer’s receipt of the Allocation Statement, the Buyer shall indicate its concurrence therewith, or propose to the Sellers any changes to the Allocation Statement. The Buyer’s failure to notify the Sellers of any objection to the Allocation Statement within forty-five (45) days after receipt thereof shall constitute the Buyer’s concurrence therewith. Should the Buyer propose any change to the Allocation Statement, the Buyer and the Sellers shall resolve any disagreement regarding the Allocation Statement in accordance with the provisions of Section 2.4(b). The allocation so determined shall be binding on the parties, and all Tax Returns filed by the Buyer, the Sellers, and each of their Affiliates, if any, shall be prepared consistently with such allocation, and none of them shall take a position on any Tax Return or other form or statement contrary to such allocation (unless required to do so by Law). Appropriate adjustments shall be made with respect to the allocation for all payments made after the Closing Date in accordance with Section 8.3(c). Each of the parties agrees to notify the other if the IRS or any other authority proposes a reallocation of amounts allocated pursuant to this Section 8.3(b).

(c) With respect to payments made after the Closing Date and not included in the original Allocation Statement, Sellers shall prepare and provide to Buyer within sixty (60) days after such payments are made a revised Allocation Statement that reflects such payments and is prepared in accordance with Section 8.3(b). Thereafter, Sellers and Buyer shall follow the same procedures contained in Section 8.3(b) in finalizing the revised Allocation Statement. The allocation so determined shall be binding on the parties, and all Tax Returns filed by the Buyer, the Sellers, and each of their Affiliates, if any, shall be prepared consistently with such allocation, and none of them shall take a position on any Tax Return or other form or statement contrary to such allocation (unless required to do so by Law). Each of the parties agrees to notify the other if the IRS or any other authority proposes a reallocation of amounts allocated pursuant to this Section 8.3(c).

8.4 S Corporation Status. Abacus and the Sellers will not revoke Abacus’s election to be treated as an S corporation. Abacus and the Sellers will not take or allow any action, other than the sale of Common Stock pursuant to this Agreement that would result in the termination of Abacus’s status as a validly electing S corporation within the meaning of Sections 1361 and 1362 of the Code.

INDEMNIFICATION

10.1 Obligations of Indemnification.

(a) Each Seller, severally and not jointly, agrees to indemnify and hold harmless Buyer and its directors, officers, agents, representatives and Affiliates and their successors and assigns (the “Buyer Indemnified Parties”) from and against any and all Losses, directly or indirectly, as a result of, or based upon or arising from (i) the breach of any of such Seller’s representations or warranties made by such Seller in Article III, and (ii) the breach of any covenant or agreement by such Seller contained in this Agreement.

(b) Subject to Section 10.4, Sellers jointly and severally agree to indemnify and hold harmless Buyer Indemnified Parties from and against any and all Losses, directly or indirectly, as a result of, or based upon or arising from (i) the breach of any representation or warranty made by Abacus contained in Article IV; (ii) the breach of any covenant or agreement by Abacus contained in this Agreement; and (iii) any Pre-Closing Taxes.

(c) Subject to Section 10.4, Buyer agrees to indemnify and hold harmless Sellers and their respective directors, partners, officers, agents, representatives and Affiliates and their successors and assigns (the “Seller Indemnified Parties” and together with Buyer Indemnified Parties, the “Indemnified Parties”) from and against any and all Losses, directly or indirectly, as a result of, or based upon or arising from (i) the breach of any representation or warranty made by Buyer contained in Article V, and (ii) the breach of any covenant or agreement by Buyer contained in this Agreement.

10.2 Procedure. An Indemnified Party shall give the Person who may be responsible for indemnification hereunder (the “Indemnifying Party”) notice (a “Claim Notice”) of any matter which an Indemnified Party has determined has given rise to, or has received a written notice of a bona fide Claim of a third party that could give rise to, a Loss under this Agreement (a “Claim”), as promptly as possible, but in any event within thirty (30) days of such determination; provided, however, that any failure of the Indemnified Party to provide such Claim Notice shall not release the Indemnifying Party from any of its obligations under this Article X except to the extent the Indemnifying Party is materially prejudiced by such failure. Each Claim Notice shall provide the assertion of any Claim in reasonable detail, including specific identification of the obligation to indemnify under Section 10.1 (including a section reference to breached representation or covenant, if applicable) and a good faith estimate of the Losses being claimed. Upon receipt of the Claim Notice, the Indemnifying Party shall be entitled to assume and control the defense of such Claim at its expense if it gives notice of its intention to do so to the Indemnified Party within five (5) Business Days of the receipt of such Claim Notice from the Indemnified Party; provided, however, that if there exists or is reasonably likely to exist a conflict of interest in the reasonable judgment of the Indemnified Party, after consultation with counsel, for the same counsel to represent both the Indemnified Party and the Indemnifying Party, then the Indemnified Party shall be entitled to retain its own counsel, in each

jurisdiction for which the Indemnified Party determines counsel is necessary, at the expense of the Indemnifying Party. In the event the Indemnifying Party exercises the right to undertake any such defense against any such Claim as provided above, the Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. Similarly, in the event the Indemnified Party is, directly or indirectly, conducting the defense against any such Claim, the Indemnifying Party shall cooperate with the Indemnified Party in such defense and make available to the Indemnified Party, at the Indemnifying Party’s expense, all such witnesses, records, materials and information in the Indemnifying Party’s possession or under the Indemnifying Party’s control relating thereto as is reasonably required by the Indemnified Party. No such Claim may be settled by the Indemnifying Party without the prior written consent of the Indemnified Party. If the Indemnifying Party makes any payment on any Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such Claim.

10.3 Survival.

(a) The representations and warranties of Sellers and Abacus contained in this Agreement shall survive for twenty-four (24) months following the Closing Date; provided, however, that (i) the representations and warranties in Sections 3.1 (Organization and Qualification of Sellers), 3.2 (Stock Ownership by Sellers), 3.3 (Authorization; Enforceability), 4.1 (Organization and Qualification of Abacus), 4.2 (Capitalization), 4.3 (Authorization; Enforceability) and 4.18 (No Brokers or Finders) shall survive the Closing indefinitely, (ii) the representations and warranties in Sections 4.7 (Taxes), 4.11 (Licenses, Permits and Authorizations) and 4.15 (Employee and Labor Matters) shall survive until ninety (90) days after the expiration of the applicable statute of limitations period, (iii) the representations and warranties in Section 4.16 (Employee Benefit Plans; ERISA) shall survive the Closing for three (3) years from the Closing Date, and (iv) the representations and warranties in Section 4.20 (Environmental Matters) shall survive for five (5) years following the Closing Date (each representation and warranty set forth in subsections (i) through (iv), a “Sellers’ Specified Representation”). Sellers’ indemnification obligations set forth in Section 10.1(b)(iii) (Pre-Closing Taxes) shall survive until ninety (90) days after the expiration of the applicable statute of limitations period. Neither the period of survival nor the liability of Sellers with respect to Sellers’ representations and warranties shall be reduced by any investigation made at any time by or on behalf of Buyer. Sellers are not required to make any indemnification payment hereunder unless a Claim is initiated prior to the expiration of the applicable survival period set forth in this Section 10.3(a), except with respect to Claims based on fraud or intentional misrepresentation by Sellers or Abacus.

(b) The representations and warranties of Buyer contained in this Agreement shall survive for twenty-four (24) months following the Closing Date; provided, however, that the representations and warranties in Sections 5.1 (Organization and Authority of Buyer; Enforceability) shall survive the Closing indefinitely (each such representation and warranty, a “Buyer’s Specified Representation”). Neither the period of survival nor the liability of Buyer with respect to Buyer’s representations and warranties shall be reduced by any investigation

made at any time by or on behalf of Buyer. Buyer is not required to make any indemnification payment hereunder unless a Claim is initiated prior to the expiration of the applicable survival period set forth in this Section 10.3(b), except with respect to Claims based on fraud or intentional misrepresentation by Buyer.

(c) Any matter as to which a Claim has been asserted by notice to the other party that is pending or unresolved at the end of any applicable limitation period shall continue to be covered by this Article X notwithstanding any applicable statute of limitations (which the parties hereby waive) until such matter is finally terminated or otherwise resolved by the parties under this Agreement or by a court of competent jurisdiction and any amounts payable hereunder are finally determined and paid.

(d) All of the covenants made by each party in this Agreement shall survive the consummation of the transactions contemplated herein until the time specified in each such covenant.

10.4 Indemnity Cushion, Cap and Allocation.

(a) Sellers shall not have any liability to any Buyer Indemnified Party with respect to Losses arising out of any of the matters referred to in Section 10.1(b) until such time as the amount of all such Losses shall collectively exceed $25,000 (the “Sellers’ Deductible”) (after which point Sellers will be obligated to indemnify Buyer Indemnified Parties from and against Losses from dollar one, i.e., including Sellers’ Deductible). Notwithstanding anything to the contrary herein, the limitation in the immediately preceding sentence shall not apply to Claims based on fraud or intentional misrepresentation of any Seller or Abacus.

(b) Subject to the next sentence, the aggregate dollar amount of all payments Sellers shall be obligated to make pursuant to this Article X shall not exceed $3,000,000 (the “Cap”). Notwithstanding anything to the contrary herein, the limitation in the immediately preceding sentence shall not apply to Claims in respect of the breach by any Seller or Abacus of any representations and warranties in Sections 4.7 (Taxes), 4.11 (Licenses, Permits and Authorizations), 4.15 (Employee and Labor Matters) and 4.16 (Employee Benefit Plans; ERISA), or any covenants in Sections 8.1 through 8.7, for which Claims the aggregate dollar amount of all payments Sellers and Abacus shall be obligated to make pursuant to this Article X shall not be subject to any limitation.

(c) Buyer shall not have any liability to any Seller Indemnified Party with respect to Losses arising out of any of the matters referred to in Section 10.1(c) until such time as the amount of all such Losses shall collectively exceed $25,000 (the “Buyer’s Deductible”) (after which point Buyer will be obligated to indemnify the Seller Indemnified Parties from and against Losses from dollar one, i.e., including Buyer’s Deductible). Notwithstanding anything to the contrary herein, the limitation in the immediately preceding sentence shall not apply to Claims based on fraud or intentional misrepresentation of Buyer.

(d) The aggregate dollar amount of all payments Buyer shall be obligated to make pursuant to this Article X shall not exceed the Cap.

(e) For purposes of determining several liability under this Article X, the aggregate liability of any Loss hereunder shall be allocated among Sellers solely based on their pro rata share of the Aggregate Purchase Price, whether or not any amounts are received by such Sellers. For instance, if Abacus’s breach of a representation results in $1,000,000 of Losses to Buyer, a Seller who is allocated 50% of the Aggregate Purchase Price shall be liable for 50% of such Losses (i.e., $500,000).

10.5 Exclusive Remedy. OTHER THAN RIGHTS TO EQUITABLE RELIEF PURSUANT TO SECTIONS 6.4 OR CLAIMS FOR FRAUD TO THE EXTENT AVAILABLE UNDER APPLICABLE LAW, EACH OF SELLERS, ON BEHALF OF HIMSELF AND EACH OF THE OTHER INDEMNIFIED PARTIES OF EACH OF SELLERS, AND BUYER, ON BEHALF OF ITSELF AND EACH OF THE OTHER INDEMNIFIED PARTIES OF BUYER, ACKNOWLEDGE AND AGREE THAT THE SOLE AND EXCLUSIVE REMEDY FOR ANY BREACH OR INACCURACY, OR ALLEGED BREACH OR INACCURACY, OF ANY REPRESENTATION OR WARRANTY IN THIS AGREEMENT OR ANY DOCUMENT EXECUTED IN CONNECTION HEREWITH OR ANY COVENANT, AGREEMENT OR ANY OTHER CAUSE OF ACTION ARISING UNDER OR RELATING TO THIS AGREEMENT OR ANY DOCUMENT EXECUTED IN CONNECTION HEREWITH, SHALL BE INDEMNIFICATION IN ACCORDANCE WITH THIS ARTICLE X. THE PROVISIONS OF THIS SECTION 10.5 SHALL NOT, HOWEVER, PREVENT OR LIMIT A CAUSE OF ACTION BASED ON FRAUD OR INTENTIONAL MISREPRESENTATION OR TO OBTAIN AN INJUNCTION OR INJUNCTIONS TO PREVENT BREACHES OF THIS AGREEMENT AND TO ENFORCE SPECIFICALLY THE TERMS AND PROVISIONS HEREOF. THE RIGHTS TO INDEMNIFICATION SET FORTH IN THIS AGREEMENT BASED ON THE REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS CONTAINED IN THIS AGREEMENT AND THE CERTIFICATES DELIVERED PURSUANT TO THIS AGREEMENT SHALL NOT BE AFFECTED BY ANY INVESTIGATION CONDUCTED, OR ANY KNOWLEDGE ACQUIRED (OR CAPABLE OF BEING ACQUIRED) AT ANY TIME, WHETHER BEFORE OR AFTER THE EXECUTION AND DELIVERY OF THIS AGREEMENT OR THE CLOSING DATE, WITH RESPECT TO THE ACCURACY OR INACCURACY OF OR COMPLIANCE WITH ANY SUCH REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT.

10.6 Tax Treatment of Indemnity Payments. Each of Sellers and Buyer agree to treat all payments made by any of them to or for the benefit of the other (including any payments to Abacus) under this Article X as adjustments to the Aggregate Purchase Price for Tax purposes and that such treatment shall govern for purposes hereof.

10.7 Offset. Amounts otherwise due to Sellers pursuant to Sections 2.2(c) and 2.3, shall be available to fund amounts due to Buyer under this Article X. To the extent Buyer has made a Claim for indemnification before a payment is due under Sections 2.2(c) and 2.3, and such Claim is not resolved, Buyer shall be permitted to withhold from such payment, and any subsequent payments, until such Claim is resolved, a reasonable amount as a reserve to cover the potential indemnification obligations of Sellers with respect to such Claim. Notwithstanding anything to the contrary herein, (i) Buyer’s right to offset under this Section 10.7 is not Buyer’s exclusive remedy and (ii) neither the exercise nor non-exercise of Buyer’s rights to offset under this Section 10.7 will constitute an election of remedies or limit Buyer in any way in the enforcement of any other remedies that may be available to it under this Agreement.

ARTICLE XI

Each party to this Agreement shall each pay such party’s own expenses incident to the negotiation, preparation and performance of this Agreement and the Transactions, including but not limited to the fees, expenses and disbursements of their accountants, financial advisors and counsel, whether or not the Closing shall have occurred; provided that any expenses of Abacus incurred prior to or at the Closing shall be the obligation of Sellers and any expenses of Abacus incurred after the Closing shall be the obligation of Buyer. Notwithstanding the foregoing, if any legal action or other legal proceeding relating to this Agreement, or the other Transactional Agreements in connection herewith, or the enforcement of any provision of such items is brought against any party hereto pursuant to Article X above, the prevailing party shall be entitled to recover reasonable attorneys’ fees, costs and disbursements (in addition to any other damages or relief to which the prevailing party may be entitled).

11.11 Arbitration.

(a) In the event the parties to this Agreement are unable to resolve a disputed claim or claims, any of the parties may request arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration will not be commenced until such amount is ascertained or all parties agree to arbitration; and in either such event the matter will be settled by arbitration conducted by three (3) arbitrators. Buyer and Sellers will each select one (1) arbitrator, and the two (2) arbitrators so selected will select a third arbitrator. The arbitrators will set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrators, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrators will rule upon motions

to compel or limit discovery and will have the authority to impose sanctions, including attorneys’ fees and costs, to the extent as a court of competent Law or equity, should the arbitrators determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of a majority of the three (3) arbitrators as to the validity and amount of any claim will be binding and conclusive upon the parties to this Agreement. Such decision will be written and will be supported by written findings of fact and conclusions which will set forth the award, judgment, decree or order awarded by the arbitrators.

(b) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration will be held in Anaheim, CA, or such other location as the parties may mutually agree, under the rules then in effect of JAMS/ Endispute.

11.12 Time of the Essence. Time is of the essence in the performance of each of the terms hereof with respect to the obligations and rights of each party hereto.

11.13 Severability. If any provision of this Agreement is determined to be invalid, illegal or unenforceable by any Governmental Entity, the remaining provisions of this Agreement to the extent permitted by Law shall remain in full force and effect; provided that the essential terms and conditions of this Agreement for all parties remain valid, binding and enforceable. In event of any such determination, the parties agree to negotiate in good faith to modify this Agreement to fulfill as closely as possible the original intents and purposes hereof. To the extent permitted by Law, the parties hereby to the same extent waive any provision of Law that renders any provision hereof prohibited or unenforceable in any respect.

11.14 Counterparts. This Agreement and any amendment hereto or any other agreement (or document) delivered pursuant hereto may be executed in one or more counterparts and by different parties in separate counterparts. All of such counterparts shall constitute one and the same agreement (or other document) and shall become effective (unless otherwise provided therein) when one or more counterparts have been signed by each party and delivered to the other party.
