The Pathlore Board (i) has determined that the First Merger and the transactions contemplated thereby are fair to, advisable and in the best interests of, Pathlore and its stockholders, (ii) has unanimously approved this Agreement, the First Merger and the other transactions contemplated by this Agreement (excluding the Second Merger and the transactions contemplated by and in connection with the Second Merger) and (iii) has determined, subject to the terms of this Agreement, to recommend the approval of this Agreement and the First Merger by the Pathlore Stockholders.

D. As a result of the Mergers, among other things, (i) all of the issued and outstanding Pathlore Capital Stock shall be converted into the right to receive the consideration as set forth herein and (ii) all issued and outstanding Pathlore Options, if not exercised prior to the effective time of the First Merger, will be terminated.

E. A portion of the consideration otherwise payable by SumTotal in connection with the First Merger shall be placed in escrow by SumTotal, and the release of such amount shall occur upon the terms and conditions, all as set forth in Article VII of this Agreement.

F. Concurrently with the execution of this Agreement, and as a condition and inducement to SumTotal’s and Pathlore’s willingness to enter into this Agreement, each of the

persons and entities identified in Exhibit A (the “Pathlore Support Stockholders”) shall have entered into a Voting Agreement in the form attached hereto as Exhibit B (the “Pathlore Voting Agreements”).

G. Concurrently with the execution of this Agreement, and as a material inducement to SumTotal’s willingness to enter into this Agreement, each of the individuals identified in Exhibit C (the “Enumerated Employees”) are executing agreements with SumTotal (each a “Employee Severance Agreement”) together with a Proprietary Information and Invention Assignment Agreement in favor of SumTotal, in each case effective upon the Closing.

H. Concurrently with the execution of this Agreement, and as a material inducement to Pathlore’s willingness to enter into this Agreement, SumTotal and each of the individuals identified in Exhibit D (the “Affiliate Stockholders”) are executing (or will execute on or before the Closing Date) a registration rights agreement in the form attached hereto as Exhibit E (the “Registration Rights Agreement”).

1.7 Effect of Mergers on Pathlore Capital Stock. Subject to the terms and conditions of this Agreement, including, without limitation, the escrow provisions set forth in Article VII, as a result of the First Merger and Second Merger, as applicable, and without any action on the part of SumTotal, Merger Sub, Pathlore or the holder of any shares of Pathlore Capital Stock or Pathlore Options, the following shall occur:

(a) Pathlore Series A Preferred Stock. Unless converted to Pathlore Common Stock in accordance with the Pathlore Certificate of Incorporation as in effect immediately prior to the effective time of the First Merger, subject to the provisions of this Section 1.7 and Sections 1.8, 1.9, 1.10 and 1.11, each share of Pathlore Preferred Stock issued and outstanding immediately prior to the effective time of the First Merger (other than Dissenting Shares), by virtue of the First Merger, will be canceled and extinguished and automatically converted into the right to receive:

(i) subject to Section 1.7(e), an amount of cash, without interest, equal to the Pathlore Preferred Per Share Cash Consideration plus the Pathlore Common Per Share Cash Consideration; and

(ii) that number of shares of SumTotal Common Stock equal to the Pathlore Preferred Per Share Stock Consideration plus the Pathlore Per Share Common Stock Amount;

provided, however, that in no event shall the aggregate cash value of the Aggregate Pathlore Preferred Cash Amount and the Aggregate Pathlore Preferred Stock Amount (the “Aggregate Preferred Consideration”) exceed $50,000,000, and in the event the Aggregate Preferred Consideration does exceed $50,000,000, any amounts in excess of $50,000,000 that would otherwise be allocated in respect of the Pathlore Preferred Stock shall be instead allocated in respect of the Pathlore Common Stock on a pro rata basis.

(b) Pathlore Common Stock. Subject to this Section 1.7 and Sections 1.8, 1.9, 1.10 and 1.11, each share of Pathlore Common Stock issued and outstanding immediately prior to the effective time of the First Merger (other than any Dissenting Shares), including shares of Pathlore Common Stock issued upon conversion of any shares of Pathlore Preferred Stock prior to the effective time of the First Merger and any shares of Pathlore Common Stock to be canceled pursuant to Section 1.7(g), will be canceled and extinguished and automatically converted into the right to receive:

(i) subject to Section 1.7(e), an amount of cash, without interest, equal to the Pathlore Common Per Share Cash Consideration; and

(ii) that number of shares of SumTotal Common Stock equal to the Pathlore Per Share Common Stock Amount (the sum of the cash value of the Pathlore Common Per Share Cash Consideration and the Pathlore Per Share Common Stock Amount to be referred to herein as the “Per Share Common Consideration” and the aggregate Per Share Common Consideration to be referred to herein as the “Aggregate Common Consideration”).

-5-

(c) Pathlore Options. Notwithstanding anything else to the contrary set forth in this Agreement, at the effective time of the Second Merger, each then unexercised and outstanding Pathlore Option shall be cancelled and extinguished in accordance with the terms of Section 5.11(b) of this Agreement and shall not be assumed by SumTotal by virtue of the Second Merger or otherwise.

(d) Establishment of Escrow Fund. On or promptly after the Effective Time, ten percent (10%) of the Merger Stock Amount (the “Escrow Shares”) and ten percent (10%) of the Merger Cash Amount (the “Escrow Cash” and together with the Escrow Shares, the “Escrow Amount”), will, without any act of any Pathlore Stockholder, and in accordance with the provisions of Section 7.3 hereof, be deposited with the Escrow Agent by SumTotal to secure the obligations set forth in Article VII hereof. Such amount is referred to herein as the “Escrow Fund” and will be governed by the terms of Article VII of this Agreement and shall serve as the sole and exclusive source of payment to and remedy of SumTotal (for any Indemnified Party) in the event of the consummation of the Mergers, except as otherwise provided in Section 7.2(f). Notwithstanding Section 1.7(a), the amount of Merger Consideration payable to any Pathlore Stockholder on the Closing Date will be reduced by such Pathlore Stockholder’s Proportionate Interest in the Escrow Amount.

(e) Stockholder Representative Expense Reimbursement.

(i) On or promptly after the Effective Time, SumTotal shall pay to the Stockholder Representative an amount equal to $250,000 (the “Expense Reimbursement Amount”), which Expense Reimbursement Amount shall be deducted on a pro rata basis from the aggregate of the Pathlore Preferred Per Share Cash Consideration and the Pathlore Common Per Share Cash Consideration based on each Pathlore Stockholder’s Proportionate Interest. For the avoidance of doubt, the Expense Reimbursement Amount constitutes a reduction to the aggregate cash consideration to be received by the Pathlore Stockholders pursuant to the First Merger. The Expense Reimbursement Amount shall be paid to the Stockholder Representative in immediately available funds to an account previously designated by the Stockholder Representative. The Expense Reimbursement Amount shall by used by the Stockholder Representative solely for the payment of out-of-pocket expenses incurred by the Stockholder Representative in connection with the performance of the Stockholder Representative’s duties and obligations hereunder. The Expense Reimbursement Amount shall be available to the Stockholder Representative in addition to any amounts permitted to be paid to the Stockholder Representative pursuant to Section 7.3(h)(ii) of this Agreement. Notwithstanding anything to the contrary herein, in no event shall any Indemnified Party have any rights in or to the Expense Reimbursement Amount.

(ii) Promptly following the distribution of the Escrow Fund pursuant to Section 7.3(b) and resolution of all pending claims identified in any Officer’s Certificate, the remainder of the Expense Reimbursement Amount, if any, shall be distributed by the Stockholder Representative to the Pathlore Stockholders based on each Pathlore Stockholder’s Proportionate Interest in the remaining Expense Reimbursement Amount.

-6-

(f) Pathlore Stockholder Consent. The holders of the Pathlore Capital Stock, by virtue of the approval of this Agreement by the Pathlore Stockholders, shall be deemed to have approved and consented to (i) the deposit of the Escrow Amount with the Escrow Agent, (ii) the deposit of the Expense Reimbursement Amount with the Stockholder Representative and (iii) all of the provisions of this Agreement. Any payments from the Escrow Fund in satisfaction of valid indemnification claims, shall be determined pursuant to Article VII of this Agreement.

(g) Cancellation of SumTotal-Owned Stock. Each share of Pathlore Common Stock held by Pathlore or owned by Merger Sub, SumTotal or any direct or indirect wholly owned Subsidiary of Pathlore or of SumTotal immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof.

(h) Capital Stock of Merger Sub. Each share of Merger Sub Common Stock issued and outstanding immediately prior to the effective time of the First Merger shall be converted into and exchanged for one validly issued, fully paid and non-assessable share of Common Stock of the Surviving Entity. Each stock certificate of Merger Sub evidencing ownership of any such shares of Merger Sub Common Stock shall, as of the effective time of the First Merger, evidence ownership of such shares of Common Stock of the Surviving Entity.

(i) Adjustments. The Aggregate Pathlore Common Stock Amount and Aggregate Pathlore Preferred Stock Amount shall each be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into SumTotal Common Stock or Pathlore Common Stock), reorganization, recapitalization, reclassification or other like change with respect to SumTotal Common Stock occurring on or after the date hereof and on or prior to the effective time of the First Merger.

(j) Fractional Shares. No fraction of a share of SumTotal Common Stock or fraction of a cent of Merger Cash will be issued or paid by virtue of the Mergers. Instead, (i) any fraction of a share of SumTotal Common Stock that would otherwise be received by a holder of Pathlore Capital Stock pursuant to Section 1.7(a) shall be aggregated and such holder of Pathlore Capital Stock shall receive, in lieu of such fraction of a share, cash (without interest) in an amount equal to such fractional part of a share of SumTotal Common Stock multiplied by the SumTotal Share Value and (ii) any fraction of a cent of Merger Cash that would otherwise be received by a holder of Pathlore Common Stock pursuant to Section 1.7(a) shall be aggregated and any remaining fraction of a cent will be rounded to the nearest whole cent, with 0.5 being rounded up.

1.8 Dissenting Shares.

(a) If any Pathlore Stockholder entitled to appraisal rights under DGCL with respect to the First Merger has properly exercised and perfected such appraisal rights pursuant to and in accordance with Section 262 of the DGCL, such holder shall, to the extent allowed under Applicable Law, be entitled to an appraisal by the Delaware Court of Chancery of the fair value of such Pathlore Stockholder’s Pathlore Capital Stock as provided in Section 262 of the DGCL, provided that such Pathlore Stockholder acts in accordance with and meets all the requirements of Section 262 of the DGCL. Prior to the Closing, SumTotal and Pathlore shall comply, and after the Closing, SumTotal shall comply, with the information delivery and other requirements pursuant to Section 262 of the DGCL and applicable Delaware law.

-7-

(b) Notwithstanding any other provision of this Agreement to the contrary, shares of Pathlore Capital Stock that have not been voted for approval of the First Merger and with respect to which such stockholders become entitled to exercise dissenters’ rights in accordance with Section 262 of DGCL (“Dissenting Shares”), will not be converted into or represent a right to receive consideration in connection with the First Merger pursuant to Section 1.7, but will instead be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to the DGCL.

(c) If a holder of Dissenting Shares (a “Dissenting Stockholder”) withdraws such holder’s demand for such payment and appraisal or becomes ineligible for such payment and appraisal, then, as of the Effective Time or the occurrence of such event of withdrawal or ineligibility, whichever last occurs, such holder’s Dissenting Shares will cease to be Dissenting Shares and will be converted into the right to receive, and will be exchangeable for, that portion of the Merger Consideration, without interest thereon, into which such Dissenting Shares would have been converted pursuant to Sections 1.7(a) and (b).

(d) Pathlore will give SumTotal and Merger Sub prompt notice of any written demands or withdrawals of dissenters’ rights with regard to Pathlore Common Stock received prior to the Effective Time, and SumTotal shall have the right to participate in all negotiations and proceedings with respect to any demands for dissenters’ rights. Pathlore agrees that, except with the prior written consent of SumTotal and Merger Sub, or as required under the DGCL, it will not make any payment with respect to, or settle or offer or agree to settle, any such demand for appraisal. Each Dissenting Stockholder who, pursuant to Section 262 of the DGCL, becomes entitled to payment of the fair value of the Dissenting Shares will receive payment therefor (but only after the value therefore has been agreed upon or finally determined pursuant to such provisions).

(e) Any amount paid by SumTotal or the Surviving Entity to any Dissenting Stockholder(s) for Dissenting Shares pursuant to Section 262 of the DGCL in excess of the value such Dissenting Stockholder(s) would have received in the First Merger for such Dissenting Shares (with shares of SumTotal Common Stock valued at the SumTotal Share Value) shall constitute “Excess Payments.” Each of SumTotal and Pathlore agree that the amount of the Excess Payments shall constitute Losses and, without regard for the limitations (but subject to the procedures) set forth in Section 7.2, SumTotal shall be entitled to recover such amount from the Escrow Fund.

1.9 Exchange Procedures; Surrender of Certificates.

(a) Exchange Agent. SumTotal’s transfer agent, Mellon Investor Services, shall act as the exchange agent for the First Merger (the “Exchange Agent”).

(b) SumTotal to Deposit Escrow Amount. On or promptly after the Effective Time, SumTotal shall deposit into an Escrow Fund the Escrow Amount. The portion of the Escrow Amount attributable to each Pathlore Stockholder shall be determined with reference to the Proportionate Interest of each such Pathlore Stockholder.

-8-

(c) SumTotal to Provide SumTotal Common Stock. On or promptly after the Effective Time, SumTotal shall make available to the Exchange Agent for exchange, in accordance with this Article I, certificates representing the shares of SumTotal Common Stock issuable by virtue of the First Merger, and on or within one (1) Business Day following the Closing Date, SumTotal shall initiate the transfer to the Exchange Agent of the cash payable pursuant to Section 1.7 (subject to the escrow and Expense Reimbursement Amount provisions of Section 1.7(d), Section 1.7(e), Section 1.9(b), and Article VII) in exchange for outstanding shares of Pathlore Capital Stock and any dividends or distributions to which holders of shares of Pathlore Capital Stock may be entitled pursuant to Section 1.9(f), such shares and cash to be held by the Exchange Agent in a fund (the “Exchange Fund”) to be distributed in accordance with this Section 1.9.

(d) Exchange Procedures. On or promptly after the Effective Time, SumTotal shall cause the Exchange Agent to deliver to each holder of record of a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented outstanding shares of Pathlore Capital Stock and which shares were converted into the right to receive the applicable consideration set forth in Section 1.7 hereof, (i) a letter of transmittal (which shall be in customary and reasonable form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the applicable consideration set forth in Section 1.7. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefore, and SumTotal shall cause the Exchange Agent to pay, such holder’s portion of the Merger Consideration as set forth in Section 1.7 hereof less the portion of (A) the Escrow Amount and (B) the Expense Reimbursement Amount contributed with respect to such holder, and the Certificate so surrendered shall forthwith be canceled. As soon as practicable after the Effective Time, and subject to and in accordance with the provisions of Article VII hereof, SumTotal shall deposit the Escrow Amount with the Escrow Agent. From the Closing and until so surrendered, each outstanding Certificate that, prior to the Effective Time, represented shares of Pathlore Capital Stock will be deemed from and after the Effective Time, for all corporate purposes, to represent solely the right to receive the applicable consideration set forth in Section 1.7 hereof.

(e) Expediting of Payments. SumTotal and Pathlore will consult and cooperate with each other prior to the Closing with the aim of expediting payment of the Merger Consideration on or promptly after the Effective Time to the Pathlore Stockholders and into the Escrow Fund.

(f) Distributions With Respect to Interchanged Shares. No dividends or other distributions declared or made after the date of this Agreement with respect to SumTotal Common Stock with a record date after the effective time of the First Merger will be paid to the holders of any unsurrendered Certificates with respect to the shares of SumTotal Common Stock represented thereby until the holders of record of such Certificates shall surrender such Certificates. Subject to

-9-

applicable law, following surrender of any such Certificates, the Exchange Agent shall deliver to the record holders thereof, in exchange therefor, without interest, certificates representing whole shares of SumTotal Common Stock issued, and Merger Cash paid and the amount of any such dividends or other distributions with a record date after the effective time of the First Merger payable with respect to such whole shares of SumTotal Common Stock.

(g) Transfers of Ownership.

Additionally, Pathlore shall prepare for filing with the California Permit application, with the cooperation of SumTotal, a related information statement or other disclosure document for the offer and issuance of the shares of SumTotal Common Stock to be received by the holders of Pathlore Common Stock in the First Merger (the “Information Statement”).

(c) In addition to the obligations of Pathlore set forth in paragraph (i) of this Section 5.6(a), Pathlore as promptly as practicable, and in any event within twenty-four (24) hours, shall advise SumTotal orally and in writing of any request received by Pathlore for information which Pathlore reasonably believes could lead to a Pathlore Acquisition Proposal or of any Pathlore Acquisition Proposal, the material terms and conditions of such request, Pathlore Acquisition Proposal or inquiry, and the identity of the person or group making any such request, Pathlore Acquisition Proposal or inquiry. Pathlore will keep SumTotal informed in all material respects of the status and details (including material amendments or proposed amendments) of any such request, Pathlore Acquisition Proposal or inquiry.

5.7 Public Disclosure. SumTotal and Pathlore will consult with each other and agree before issuing any press release, making any public statement or otherwise making any disclosure with respect to the First Merger, this Agreement (including the Pathlore Schedules) or a Pathlore Acquisition Proposal and will not issue any such press release or make any such public statement or other disclosure prior to such agreement, except to the extent necessary in order to comply with (i) Sections 5.2 (California Permit; Fairness Hearing), 5.4 (Pathlore Stockholder Approval) and 5.8 (Third Party Consents), and (ii) applicable law or any listing agreement with a national securities exchange or the Nasdaq National Market. In the event either SumTotal or Pathlore (or any of their respective representatives) are requested to, or required by, applicable law or regulation (including, without limitation, any rule, regulation or policy statement of any national securities exchange, market or automated quotation system on which any of such party’s securities are listed or quoted)

-53-

or by legal process to disclose any of the foregoing, the disclosing party (the “Disclosing Party”) shall notify the other party (the “Non-Disclosing Party”) with prompt notice of such request or requirement in order to enable the Non-Disclosing Party (i) to seek an appropriate protective order or other remedy, (ii) to consult with the Disclosing Party with respect to the Non-Disclosing Party’s taking steps to resist or narrow the scope of such request or legal process or (iii) to waive compliance in whole or in party with the terms of this Section 5.7 and the Confidentiality Agreement. In the event that such protective order or other remedy is not obtained, or the Non-Disclosing Party waives compliance, in whole or in party, with the terms of this Section 5.7 and the Confidentiality Agreement, the Disclosing Party or its representative shall use commercially reasonable efforts to disclose only that portion of such disclosure that is legally required to be disclosed and to ensure that any information deemed to be “Proprietary Information” under the Confidentiality Agreement that is disclosed will be accorded confidential treatment.

5.9 Notification of Certain Matters. SumTotal will give prompt notice to Pathlore, and Pathlore will give prompt notice to SumTotal, of the occurrence, or failure to occur, of any event, which occurrence or failure to occur would be reasonably likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate at any time from the date of this Agreement to the Effective Time, or any failure of SumTotal or Pathlore, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Sections 6.2(a) or (b) or 6.3(a) or (b), as the case may be, would not be satisfied as a result thereof. Additionally, to the extent not otherwise publicly disclosed by SumTotal in its filings with the SEC, SumTotal will give prompt notice to Pathlore in the event SumTotal believes that a Material Adverse Effect shall have occurred at any time from the date of this Agreement to the Effective Time. Notwithstanding any of the foregoing, the delivery of any notice pursuant to this section will not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

7.2 Indemnification by Pathlore Stockholders.

(a) Scope of Indemnification. From and after the Effective Time, the Pathlore Stockholders who have received, or shall be entitled to receive, Merger Consideration pursuant to Section 1.7 of this Agreement (the “Indemnitors”), shall indemnify and hold harmless, and the Escrow Fund shall be available to compensate, each of SumTotal and its officers, directors and affiliates, including the Surviving Entity (each, an “Indemnified Party” and collectively, the “Indemnified Parties”) from and against any Losses paid, incurred, accrued or sustained by the Indemnified Parties (regardless of whether or not such Losses are related to any third-party claim) and which arise from or as a result of the following (it being understood that without limiting an Indemnified Party’s right to recover from the Escrow Fund fully for any particular Loss, a Pathlore Stockholder shall only be responsible to indemnify the Indemnified Party, by virtue of such stockholder’s participation in the Escrow Fund, for an amount equal to such stockholder’s Proportionate Interest with respect to such Loss):

(i) without giving effect to any update of or modification to the Pathlore Schedules made or purported to be made after the date of this Agreement, any breach of any representation or warranty made by Pathlore in this Agreement, including and subject to the Pathlore Schedules, or in any certificate delivered by Pathlore at the Closing, or any failure of any such representation or warranty to be true and correct as of the date of this Agreement and as of the Closing Date (as though such representation and warranty were made as of the Closing Date), or in the case of representations and warranties which by their terms speak only as of a specific date or dates, to be true and correct as of such specific date or dates;

-64-

(ii) any breach of any covenant or obligation of Pathlore in this Agreement required to be performed prior to the Closing Date;

(iii) any Excess Payments to Dissenting Stockholders;

(iv) any Undisclosed Excess Expense Amount; or

(v) any Agreed Claim (as provided in Section 7.2(i)).

(b) Surviving Entity Losses. It is understood and agreed that if the Surviving Entity suffers, incurs or otherwise becomes subject to any Losses indemnifiable under Section 7.2(a) as a result of or in connection with any inaccuracy in or breach of any representation, warranty, pre-closing covenant or obligation set forth in this Agreement, including the Pathlore Schedules, or in any certificate delivered by Pathlore at the Closing, then (without limiting any of the rights of the Surviving Entity as an Indemnified Party), SumTotal shall also be deemed, by virtue of its ownership of the stock of the Surviving Entity, to have incurred Losses as a result of and in connection with such inaccuracy or breach.

(c) Threshold. Subject to the exceptions set forth in this Section 7.2(c) and Section 7.2(i), the Indemnitors shall not be required to make any indemnification payment pursuant to (i) Section 7.2(a)(i) for any inaccuracy in or breach of any representation or warranty in this Agreement or (ii) Section 7.2(a)(ii) for any breach of a covenant in this Agreement (other than knowing breaches of covenants) unless the aggregate amount of all such Losses exceeds on a cumulative and aggregate basis $250,000 (the “Threshold Amount”), in which case such Indemnified Party shall be entitled to recover all Losses indemnifiable hereunder in excess of the Threshold Amount, subject to Sections 7.2(d), (e), (f), (g) and (h). Notwithstanding the foregoing, SumTotal shall be entitled to recover for, and the Threshold Amount shall not apply as a threshold to, any and all claims or payments made with respect to (X) Losses incurred pursuant to Sections 7.2(a)(ii) (only with respect to knowing breaches of covenants), 7.2(a)(iii), 7.2(a)(iv) and 7.2(a)(v) hereof, (Y) claims in respect of fraud or willful breach of this Agreement, including the Pathlore Schedules, or any certificate delivered by Pathlore at the Closing, or (Z) Losses that arise from or as a result of any inaccuracy in or breach of any representation or warranty of Pathlore contained in Section 2.2 or Section 2.3 of the Agreement.

(d) No Contribution. Each Indemnitor in its capacity as a Pathlore Stockholder waives and acknowledges and agrees that he/she/it will not have and shall not exercise or assert (or attempt to exercise or assert) any right against Pathlore or any of its Subsidiaries or the Surviving Entity of contribution, right of indemnity of other right or remedy in connection with any indemnification obligation of such Indemnitor under Section 7.2 hereof. This provision is not intended to otherwise limit the operation of Section 5.20 hereof.

-65-

(e) Indemnification Procedures. If an Indemnified Party seeks indemnification under this Article VII, the Indemnified Party shall deliver an Officer’s Certificate to (x) the Stockholder Representative and Escrow Agent if making a claim against the Escrow Fund pursuant to Section 7.3(d), or (y) the Stockholder Representative if making a claim other than against the Escrow Fund.

(f) Escrow as the Sole Remedy. Notwithstanding anything to the contrary herein, if the First Merger is consummated, the Escrow Fund shall be the sole and exclusive remedy for any claim made by any of the Indemnified Parties for Losses resulting from, arising out of or relating to this Agreement, including the Pathlore Schedules or any certificate delivered by Pathlore at the Closing, and the First Merger, other than Losses resulting from fraud in connection with this Agreement, including the Pathlore Schedules or any certificate delivered by Pathlore at the Closing.

Notwithstanding anything contained herein to the contrary, nothing shall prohibit SumTotal from seeking and obtaining recourse against a Pathlore Stockholder in the event that SumTotal issues to such Pathlore Stockholder, or any of them, more than the Merger Consideration to which such stockholder is entitled pursuant to Article I of this Agreement.

(g) Insurance Proceeds. Losses that may be recovered from the Escrow Fund shall take account of and be reduced by the amount of any insurance proceeds actually recovered by the Indemnified Party in respect thereof less that portion of any premium increase in the next policy period that results from the assertion of such claim. Nothing in this Section 7.2(g) shall obligate any Indemnified Party to obtain or maintain insurance with respect to any matters for which it is entitled to seek indemnification under this Agreement.

(h) Mitigation. SumTotal agrees that in the event of Losses that may be offset against the remaining Pathlore payment obligations under that certain Stock Purchase Agreement, dated as of August 11, 2004, by and between Pathlore and David Kripke (the “DK Agreement”), SumTotal shall first offset against such future payments to the extent permissible under Section 9.04 of the DK Agreement before obtaining recovery from the Escrow Fund (it being understood that if SumTotal cannot offset its Losses pursuant to the DK Agreement without objection from David Kripke, (the “DK Losses”) then such DK Losses may be recovered in accordance with the provisions of Section 7.2). In the event that David Kripke raises an objection to the right of offset asserted by SumTotal, the Stockholder Representative may, at its sole cost and expense, dispute and pursue such objection on behalf of SumTotal and, if successful, any recovery shall be deposited into the Escrow Fund to replace Losses paid to SumTotal if and only if an Indemnified Party has not recovered the DK Losses in accordance with Article VII. If an Indemnified Party has recovered its DK Losses in accordance with this Article VII, then the Stockholder Representative shall be entitled to retain and distribute to the Pathlore Stockholders any recovery in respect of the challenged objection to the right of set off asserted by SumTotal obtained by the Stockholder Representative in connection with the challenge of the objection.

(i) Agreed Claims. Section 2.10(b) of the Pathlore Schedules sets forth the treatment of certain third-party claims (each, an “Agreed Claim”) for purposes of the application of the provisions of Article VII. Except as set forth in Section 2.10(b) of the Pathlore Schedules,

-66-

nothing herein shall modify the rights and obligations set forth in Article VII, which shall continue to apply to each Agreed Claim. Notwithstanding anything to contrary herein, other than Sections 7.2(e), 7.2(f) and 7.2(g), (i) Losses sought to be recovered pursuant to Section 7.2(a)(v) shall be indemnifiable solely and exclusively in accordance with the limitations set forth in Section 2.10(b) of the Pathlore Schedules, and (ii) indemnification for any Agreed Claim shall be sought solely and exclusively under Section 7.2(a)(v).

7.3 Escrow Arrangements.

(a) Escrow Fund. As soon as practicable after the Effective Time, SumTotal will deposit the Escrow Amount with the Escrow Agent, such deposit to constitute the Escrow Fund to be governed by the terms set forth herein and at SumTotal’s cost and expense. The portion of the Escrow Amount contributed with respect to each of the Pathlore Stockholders shall be in proportion to the aggregate Merger Consideration to which each such Pathlore Stockholder would otherwise be entitled to receive pursuant to Section 1.7. The Escrow Amount shall be allocated in proportion to the number of Merger Shares and amount of Merger Cash payable at the Effective Time to each of the Pathlore Stockholders.

(b) Escrow Period; Distribution upon Termination of Escrow Periods. Subject to the following requirements, the Escrow Fund shall be in existence immediately following the Effective Time and shall terminate at 11:59 p.m. Pacific time on the Escrow Termination Date (the “Escrow Period”); provided that the Escrow Period shall not terminate with respect to (and only to) such amount that is reasonably necessary to satisfy any unsatisfied claims concerning facts and circumstances existing prior to the termination of such Escrow Period and to the extent specified in any Officer’s Certificate delivered to the Escrow Agent and Stockholder Representative prior to termination of such Escrow Period (“Eligible Claims”). As soon as all Eligible Claims have been resolved pursuant to the terms hereof, the Escrow Agent shall transfer to the Pathlore Stockholders the remaining portion of the Escrow Fund, if any, not required to satisfy the Eligible Claims. To the extent the Escrow Fund exceeds the amount of Eligible Claims on or after the Escrow Termination Date, the Escrow Agent shall transfer to the Pathlore Stockholders the amount, if any, of any excess above the amount of the Eligible Claims then remaining in the Escrow Fund.

-67-

(i) The Escrow Agent shall hold and safeguard the Escrow Fund during the Escrow Period, shall treat such fund as a trust fund in accordance with the terms of this Agreement and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof. All income earned on the cash in the Escrow Fund, if any, shall become part of, and be held as an additional portion of the Escrow Fund in proportion to each Pathlore Stockholder’s original share of the Escrow Fund. The parties hereto agree that the Pathlore Stockholders, based on each Pathlore Stockholder’s Proportionate Interest, shall be the owners of any cash contained in the Escrow Fund, and that all interest on or other taxable income, if any, earned from the investment of cash contained in the Escrow Fund shall be treated for Tax purposes as earned by such Pathlore Stockholder. At the end of each calendar year, an amount equal to the income earned from the investment of cash contained in the Escrow Fund for the preceding taxable year (or portion thereof) shall be distributed to the Pathlore Stockholders in proportion to each applicable stockholder’s Proportionate Interest.

(ii) Any shares of SumTotal Common Stock or other equity securities issued or distributed by SumTotal (including shares issued upon a stock split) (“New Shares”) in respect of shares of SumTotal Common Stock in the Escrow Fund which have not been released from the Escrow Fund as of the time of such issuance or distribution by SumTotal shall be added to the Escrow Fund and become a part thereof. Cash dividends on SumTotal Common Stock and New Shares issued in respect of shares of SumTotal Common Stock which have been released from the Escrow Fund as of the time of such issuance or distribution by SumTotal shall not be added to the Escrow Fund but shall be distributed to the Pathlore Stockholders in proportion to their Proportionate Interest in the Escrow Fund.

(iii) Each Pathlore Stockholder shall be entitled to control the vote of such stockholder’s Proportionate Interest in the shares of SumTotal Common Stock held in the Escrow Fund (and on any voting securities added to the Escrow Fund in respect of such shares of SumTotal Common Stock), and the Escrow Agent in whose name the shares are held shall vote such shares on all matters as instructed by the respective stockholders in writing.

(iv) So long as the closing sales price for one share of SumTotal Common Stock as reported on the Nasdaq National Market on the day before any sale under this Section 7.3(c)(iv) is equal to or greater than the SumTotal Stock Price, the Stockholder Representative, on behalf of the Pathlore Stockholders, may from time to time direct the Escrow Agent to sell Escrow Shares for cash, and the proceeds (net of ordinary and reasonable commissions) of any such sale shall be added to the Escrow Fund and be available for recovery under Section 7.2. In connection with any sale of Escrow Shares pursuant to this Section 7.3(c)(iv), the Escrow Agent shall be entitled to receive and rely upon written direction from the Stockholder Representative as to the manner and method to carry out such sale, including without limitation (i) identifying the number of shares to be sold, (ii) identifying the brokerage firm the Stockholder Representative requests to be used or instructing the Escrow Agent to use its affiliated brokerage service, and (iii) setting forth any necessary or special instructions with respect to the sale (including any stop loss or minimum price per share instructions).

-68-

(v) The Escrow Agent shall invest and reinvest the Escrow Fund at the joint written instructions of SumTotal and the Stockholder Representative. In the absence of joint written directions from SumTotal and the Stockholder Representative, the Escrow Fund shall be invested in a U.S. Bank Money Market account. The joint written instructions shall specify that the Escrow Fund shall be invested in any one or combination of the following: (a) readily marketable direct obligations of the Government of the United States or any agency or instrumentality thereof or readily marketable obligations unconditionally guaranteed by the full faith and credit of the Government of the United States, (b) insured certificates of deposit, of or time deposits with, any commercial bank that issues commercial paper (rated as described in clause (c) below), is organized under the laws of the United States or any State thereof and has combined capital and surplus of at least $1 billion, (c) commercial paper issued by any corporation organized under the laws of any State of the United States, rated at least “Prime-1” (or then equivalent grade) by Moody’s Investors Services, Inc. or “A-1” (or then equivalent grade) by Standard & Poors, Inc. or (d) money market funds that invest solely in direct obligations of the U.S. government.

(d) Claims Upon Escrow Fund. Subject to Section 7.2(e) and Section 7.2(i) hereof, upon receipt by the Escrow Agent and the Stockholder Representative at any time on or before the last day of the Escrow Period of a certificate signed by any officer of SumTotal (an “Officer’s Certificate”): (i) stating that an Indemnified Party has paid, incurred, accrued, sustained or reasonably anticipates that it will have to pay, incur, accrue or sustain Losses indemnifiable under Section 7.2(a), and (ii) specifying in reasonable detail the amount of such Loss, the individual items of Losses included in the amount so stated, the date each such item was paid, incurred, accrued or sustained, and the basis for such reasonably anticipated payment, incurrence, accrual or sustaining, and the nature of the misrepresentation, breach of warranty or pre-closing covenant, Excess Payment to Dissenting Stockholder(s) or Undisclosed Excess Expense Amount to which such item is related, the Escrow Agent shall, subject to the provisions of Section 7.2(e) and Section 7.2(i) hereof, transfer to SumTotal out of the Escrow Fund, as promptly as practicable, funds and shares of SumTotal Common Stock held in the Escrow Fund in an amount equal to such Losses. With respect to each Pathlore Stockholder, such payments from the Escrow Fund will be made by multiplying the amount of the aggregate payment from the Escrow Fund by such Pathlore Stockholder’s Proportionate Interest and shall be allocated between the cash and stock contributed to the Escrow Fund attributable to such Pathlore Stockholder in the ratio of the cash and stock originally deposited in the Escrow Account. Prior to any distribution of cash or stock from the Escrow Fund to SumTotal, the Pathlore Stockholders or the Stockholder Representative, SumTotal and the Stockholder Representative shall deliver a certificate to the Escrow Agent showing the remaining balance of the amount of shares and cash held in the Escrow Fund after giving effect to such distribution. For purposes of determining the number of shares of SumTotal Common Stock to be delivered to SumTotal out of the Escrow Fund pursuant to this Section 7.2(d), the shares of SumTotal Common Stock shall be valued at the SumTotal Stock Price.

(e) Objections to Claims. At the time of delivery of any Officer’s Certificate to the Escrow Agent, a duplicate copy of such certificate shall be delivered to the Stockholder Representative (with receipt by the Stockholder Representative confirmed by the Escrow Agent) and for a period of thirty (30) days after such delivery, the Escrow Agent shall make no transfer to

-69-

SumTotal of any Escrow Amounts pursuant to Section 7.2(d) hereof unless the Escrow Agent shall have received written authorization from the Stockholder Representative to make such transfer. After the expiration of such thirty (30) day period, the Escrow Agent shall transfer the funds from the Escrow Fund in accordance with Section 7.2(d) hereof, provided that no such transfer may be made if the Stockholder Representative shall object in a written statement to the claim made in the Officer’s Certificate, and such statement shall have been delivered to the Escrow Agent prior to the expiration of such thirty (30) -day period.

(f) Resolution of Conflicts; Arbitration.

(i) In case the Stockholder Representative shall object in writing to any claim or claims made in any Officer’s Certificate as provided in Section 7.3(e) hereof, the Stockholder Representative and SumTotal shall attempt in good faith to resolve all existing disputes and, if possible, agree upon the rights of the respective parties with respect to each of such claims. If the Stockholder Representative and SumTotal should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and distribute funds from the Escrow Fund in accordance with the terms thereof.

(ii) If no such agreement can be reached after good faith negotiations for thirty (30) days after receipt by the Escrow Agent of the written objection of the Stockholder Representative, either SumTotal or the Stockholder Representative may demand 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 shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. SumTotal and the Stockholder Representative shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The arbitrators shall 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 shall rule upon motions to compel or limit discovery and shall 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. In addition, the arbitrators shall be empowered to require any one or more of the parties to bear all or any portion of the costs and fees incurred as a result of the arbitration in the event that the arbitrators determine a party has acted unreasonably or in bad faith in connection with the negotiation or resolution of the underlying claim that is the subject of such arbitration. The decision of a majority of the three arbitrators as to the validity and amount of any claim in such Officer’s Certificate shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 7.3(e) hereof, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance therewith. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrators.

-70-

(iii) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in New Castle County, Delaware administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures as then in effect. The non-prevailing party to an arbitration (as determined by the arbitrator) shall pay its own expenses, the fees of each arbitrator, the administrative costs of the arbitration, and the expenses, including without limitation, reasonable attorneys fees and costs, incurred by the other party to the arbitration. In any arbitration where the Stockholder Representative is the non-prevailing party, all such expenses, fees and costs shall be paid out of the Escrow Amount after all distributions to SumTotal are made in satisfaction of any such claims and prior to any distribution to the Pathlore Stockholders.

(g) Third-Party Claims. In the event SumTotal becomes aware of a third-party claim, action or proceeding that SumTotal reasonably believes may result in a demand against the Escrow Fund, SumTotal shall promptly notify the Stockholder Representative of such claim, action or proceeding, and the Stockholder Representative shall be entitled, at its expense, to participate in any defense of such claim. If there is a third-party claim that, if adversely determined, would give rise to a right of recovery for Losses hereunder, then any amounts incurred or accrued in defense of such third-party claim (including reasonable counter-claims), regardless of the outcome of such claim, shall be deemed Losses hereunder and shall be subject to the limitations set forth in Section 2.10(b) of the Pathlore Schedules with respect to Agreed Claims (it being understood that any amounts awarded in connection with any such counter-claims shall be first offset against any Losses subject to indemnification (and limits thereto) hereunder and incurred in connection with the underlying third-party claim). SumTotal shall have the right in its sole discretion to control the defense of all such claims and to settle all such claims; provided, however, that SumTotal shall not settle any third-party claims without the prior written consent of the Stockholder Representative, which consent will not be unreasonably withheld or delayed. To the extent the Stockholder Representative presents the Indemnified Party with a bona fide offer from the third-party claimant regarding a settlement for money damages in an amount which, taken together with all Losses relating to the underlying third-party claims, is less than the value remaining in the Escrow Fund that is not already subject to existing claims pursuant to an Officer’s Certificate or Certificates, and which offer includes no material obligations or restrictions on SumTotal or its business other than the payment of money damages, then SumTotal may elect to (A) settle the third-party claims on the proposed terms and conditions of the proposed settlement in which case SumTotal shall recover the full amount of such settlement (and related Losses) from the Escrow Fund pursuant to Article VII without any objection from the Stockholder Representative, subject to the limitations on recovery provided in Section 7.2(i) with respect to Agreed Claims or (B) reject the settlement in which case SumTotal agrees and acknowledges that is shall thereafter be responsible for all Losses in excess of the proposed settlement offer (including litigation expenses incurred thereafter). The Indemnified Party shall keep the Stockholder Representative informed of any settlement proposals and the parties shall consult and cooperate with each other in good faith in connection with any such third-party claims.

-71-

(h) Stockholder Representative; Power of Attorney.

(i) In the event that the First Merger is approved, effective upon such vote, and without further act of any stockholder, Mr. James Collis shall be appointed as agent and attorney-in-fact (the “Stockholder Representative”) for each Pathlore Stockholder (except such stockholders, if any, as shall have exercised their dissenters’ rights under the DGCL), for and on behalf of the Pathlore Stockholders, to do and perform every act and thing required or permitted to be done by any Pathlore Stockholder in connection with Article VII of this Agreement and the matters contemplated thereby, including to give and receive notices and communications, to authorize delivery to SumTotal of cash and stock from the Escrow Fund in satisfaction of claims by SumTotal, to object to such deliveries, to engage and employ agents and representatives (including accountants, legal counsel and other professionals) and to incur such other expenses as deemed necessary or prudent, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of the Stockholder Representative for the accomplishment of the foregoing. Such agency may be changed by the Pathlore Stockholders from time to time upon not less than thirty (30) days prior written notice to SumTotal; provided that the Stockholder Representative may not be removed unless holders of a two-thirds interest of the Escrow Fund agree to such removal and to the identity of the substituted agent. Any vacancy in the position of Stockholder Representative may be filled by approval of the holders of a majority in interest of the Escrow Fund. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall not receive compensation for his or her services. The out-of-pocket fees and expenses incurred by the Stockholder Representative in connection with the performance of his duties and obligations hereunder shall be paid first from the Expense Reimbursement Amount in accordance with Section 1.7(e). Notices or communications to or from the Stockholder Representative shall constitute notice to or from each of the Pathlore Stockholders. The Stockholder Representative shall notify each of the Pathlore Stockholders, at the address set forth on the Spreadsheet (or such other address delivered in writing to the Stockholder Representative), of any claim made by an Indemnified Party hereunder pursuant to Section 7.3(d).

(ii) The Stockholder Representative shall not be liable for any act done or omitted hereunder as Stockholder Representative in good faith, absent bad faith or willful misconduct. The Pathlore Stockholders on whose behalf the Escrow Amount was contributed to the Escrow Fund shall severally indemnify the Stockholder Representative from the Escrow Fund and hold the Stockholder Representative harmless against any loss, liability or expense incurred without bad faith or willful misconduct on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of the Stockholder Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Stockholder Representative. Subject to Section 1.7(e), all other reasonable expenses incurred by the Stockholder Representative shall be paid out of the Escrow Amount after all distributions to SumTotal are made in satisfaction of any claims on the Escrow Fund and prior to any distribution to the Pathlore Stockholders.

-72-

(i) Actions of the Stockholder Representative. A decision, act, consent or instruction of the Stockholder Representative shall constitute a decision of all the Pathlore Stockholders for whom a portion of the Escrow Amount otherwise issuable to them are deposited in the Escrow Fund and shall be final, binding and conclusive upon each of such stockholders, and the Escrow Agent and SumTotal may rely upon any such decision, act, consent or instruction of the Stockholder Representative as being the decision, act, consent or instruction of each such Pathlore Stockholder. The Escrow Agent and SumTotal are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholder Representative.

(j) Escrow Agent’s Duties.

(i) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth herein, and any additional written escrow instructions that the Escrow Agent may receive after the date of this Agreement that are signed by an officer of SumTotal and the Stockholder Representative, and may rely on and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow Agent while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith, provided that the Escrow Agent has exercised reasonable care in the selection of such counsel.

(ii) The Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person, excepting only orders or process of courts of law or the arbitrators, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or the arbitrators. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(iii) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder absent gross negligence or willful misconduct.

(iv) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent absent gross negligence or willful misconduct.

(v) In performing any duties under the Agreement, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except for gross negligence or willful misconduct on the part of the Escrow Agent. The Escrow Agent shall not incur any such liability for (A) any act or failure to act made or omitted in good faith, or (B) any action taken or omitted in

-73-

reliance upon any instrument, including any written statement of affidavit provided for in this Agreement that the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with the legal counsel in connection with Escrow Agent’s duties under this Agreement and shall be fully protected in any act taken, suffered, or permitted by him/her in good faith in accordance with the advice of counsel provided that the Escrow Agent has exercised reasonable care in the selection of such counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any party to this Agreement.

(vi) If any controversy arises between the parties to this Agreement, or with any other party, concerning the subject matter of this Agreement, its terms or conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may hold all documents and funds held in escrow and may wait for settlement of any such controversy by final appropriate legal proceedings. In such event, the Escrow Agent will not be liable for damage.

Furthermore, the Escrow Agent may at its option, file an action of interpleader requiring the parties to answer and litigate any claims and rights among themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents and funds held in escrow, except all cost, expenses, charges and reasonable attorneys fees incurred by the Escrow Agent due to the interpleader action and which the parties jointly and severally agree to pay. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liabilities imposed by the terms of this Agreement.

(vii) The parties and their respective successors and assigns agree jointly and severally to indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, attorneys fees, and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of his/her duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter.

(viii) The Escrow Agent may resign at any time upon giving at least thirty (30) days written notice to SumTotal and the Stockholder Representative; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows: SumTotal and the Stockholder Representative shall use all reasonable efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If SumTotal and the Stockholder Representative fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a successor escrow agent authorized to do business in the State of California. The successor escrow agent shall execute and deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers and duties of the predecessor escrow agent as if originally named as escrow agent. The Escrow Agent shall be discharged from any further duties and liability under this Agreement.

-74-

(k) Fees. All fees of the Escrow Agent for performance of its duties hereunder shall be paid by SumTotal. It is understood that the fees and usual charges agreed upon for services of the Escrow Agent shall be considered compensation for ordinary services as contemplated by this Agreement. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not provided for in this Agreement, or if the parties request a substantial modification of its terms, or if any controversy arises, or if the Escrow Agent is made a party to, or intervenes in, any litigation pertaining to this escrow or its subject matter, the Escrow Agent shall be reasonably compensated by SumTotal for such extraordinary services and reimbursed for all costs, attorneys fees, and expenses occasioned by such default, delay, controversy or litigation.

(d) by SumTotal if the Pathlore Stockholder Approval has not been obtained; provided, however, that the right to terminate this Agreement under this Section 8.1(d) shall not be available to SumTotal if its action or failure to act has been a principal cause of the failure of the First Merger to occur on or before such date and such action or failure to act by SumTotal constitutes a breach of this Agreement;

(e) by Pathlore, upon a breach of any representation, warranty, covenant or agreement on the part of SumTotal set forth in this Agreement, or if any representation or warranty of SumTotal shall have become untrue, in either case such that the conditions set forth in Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time of such breach or as of the time

-75-

such representation or warranty shall have become untrue, provided, that if such inaccuracy in SumTotal’s representations and warranties or breach by SumTotal is curable by SumTotal within the earlier of thirty (30) days or the date set forth in Section 8.1(b) through the exercise of all reasonable efforts, then Pathlore may not terminate this Agreement under this Section 8.1(e) until the earlier of thirty (30) days or such fewer number of days before the date set forth in Section 8.1(b) after delivery of written notice from Pathlore to SumTotal of such breach, provided SumTotal continues to exercise all reasonable efforts to cure such breach (it being understood that Pathlore may not terminate this Agreement pursuant to this paragraph (e) if such breach by SumTotal is cured during such period); or

(f) by SumTotal, upon a breach of any representation, warranty, covenant or agreement on the part of Pathlore set forth in this Agreement, or if any representation or warranty of Pathlore shall have become untrue, in either case such that the conditions set forth in Section 6.3(a) or Section 6.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided, that if such inaccuracy in Pathlore’s representations and warranties or breach by Pathlore is curable by Pathlore within the earlier of thirty (30) days or the date set forth in Section 8.1(b) through the exercise of all reasonable efforts, then SumTotal may not terminate this Agreement under this Section 8.1(f) until the earlier of thirty (30) days or such fewer number of days before the date set forth in Section 8.1(b) after delivery of written notice from SumTotal to Pathlore of such breach, provided Pathlore continues to exercise all reasonable efforts to cure such breach (it being understood that SumTotal may not terminate this Agreement pursuant to this paragraph (f) if such breach by Pathlore is cured during such period).

Any termination of this Agreement under Section 8.1 above will be effective immediately upon the delivery of written notice of the terminating party to the other parties hereto (or such later time as may be contemplated by Section 8.1(e) and 8.1(f)). In the event of the termination of this Agreement as provided in Section 8.1, this Agreement shall be of no further force or effect and no party hereto shall have any liability hereunder, except (i) as set forth in Section 5.3(c), this Section 8.2, Section 8.3 and Article IX (General Provisions), each of which shall survive the termination of this Agreement, and (ii) nothing herein shall relieve any party from liability for any willful breach of this Agreement. This Section 8.2 shall not impair the right of any party to compel specific performance by another party of its obligations hereunder.

8.3 Fees and Expenses. Whether or not the First Merger is consummated, all fees and expenses incurred in connection with the Mergers including, without limitation, all legal, accounting, financial advisory, consulting, investment banking and all other fees and expenses of third parties (excluding amounts paid pursuant to Section 5.18(b), “Third Party Expenses”) incurred by a party hereto in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated hereby, shall be the obligation of the respective party incurring such fees and expenses; provided, however, that in the event that the First Merger is consummated, SumTotal agrees to pay at Closing up to an aggregate of $700,000 (the “Expense Cap”) in reasonable and documented Third Party Expenses incurred by Pathlore in connection with the Mergers and listed on the Statement of Expenses; and provided, further, that to the extent the

-76-

aggregate Third Party Expenses listed on the Statement of Expenses exceed the Expense Cap, the Merger Cash Amount shall be reduced dollar-for-dollar (such excess being, the “Disclosed Excess Expense Amount”). Any Third Party Expenses incurred by Pathlore in connection with the Mergers in excess of the Expense Cap that are not reflected in full on the Statement of Expenses (collectively the “Undisclosed Excess Expense Amount”) shall be subject to the indemnification procedures set forth in Section 7.2 (it being understood that Third Party Expenses not included on the Statement of Expenses, but incurred after the Closing Date and, which together with those Third Party Expenses disclosed on the Statement of Expenses, are not in excess of the Expense Cap, shall not be deemed to be part of the Undisclosed Excess Expense Amount and shall be paid by SumTotal).
