in the Plan. Each Participant’s targeted cash incentive opportunity is expressed as a percentage

(b) Promissory notes made payable to each Seller in an original principal amount equal to the
Seller’s Pro Rata Share of (i) Two Million Dollars ($2,000,000) minus (ii) all amounts
outstanding (including without limitation all accrued interest) under the Initial Note as of the
Closing Date (with the principal amounts and the payments due thereunder further adjusted pursuant
to clauses (i) and (ii) of this Section 2.1(b), below) in the form attached hereto as
Exhibit A (each, a “Promissory Note”), with the principal under such Promissory
Notes payable as follows:

(i) One Million Dollars ($1,000,000) minus the amount by which Estimated Net Worth is
less than the Net Worth Target (i.e., the amount by which the Estimated Net Worth is a greater
negative number than the Net Worth Target), if applicable, with such estimate determined in
accordance with Section 2.3(a) hereof, due and payable on March 1, 2008 (it being agreed by
the parties that there shall be no adjustment to the first payment under the Promissory Notes to

(ii) The remaining balance, as adjusted pursuant to Section 2.4 hereof, due and
payable on January 1, 2009.

Hundred Thousand Dollars ($5,200,000), divided by (ii) the volume weighted average closing price
of the Purchaser Common Stock for the twenty (20) trading days immediately preceding the earlier

terms of the transactions contemplated by this Agreement; provided, however, that

released to the Sellers as follows: (i) One Million (1,000,000) of the Purchaser Shares will be
held back by the Purchaser (the “Holdback Shares”) in escrow for a period of two (2) years
following the Closing to partially secure the indemnification obligations of the Sellers set forth
in Section 8 hereof; and (ii) within five (5) Business Days of the date revenues are
received by the Company from Pacific Texas Pipeline (“PTP”) following the Closing
(determined on a cash-received basis, and not an accrual or booked revenues basis) and verified by
the Purchaser to its reasonable satisfaction, the Purchaser shall issue to the Sellers a number of
Purchaser Shares equal to the product obtained by multiplying:

(A) the quotient obtained by dividing (1) the total number of Purchaser Shares as determined
by the first paragraph of this Section 2.1(a) above less the Holdback Shares by (2)
Seven Million Six Hundred Five Thousand (7,605,000) by

(B) the dollar amount of cash revenues so received by the Company from PTP and verified by the
Purchaser.

For purposes of clarity and solely by way of example, (A) if the total number of Purchaser Shares
less the Holdback Shares is 12,000,000, and following the Closing the Company receives, and the
Purchaser verifies the receipt of, $1,000,000 in cash revenues from PTP, the Sellers would receive,
within five (5) Business Days of such verification, a total of 1,577,909 Purchaser Shares, and (B)
if and when an aggregate of $7,605,000 of cash revenues have been received by the Company from PTP
following the Closing and verified by the Purchaser, all of the Purchaser Shares (less the Holdback
Shares) will have been released to the Sellers. In addition, for purposes of clarity, any amounts
received from PTP prior to the Closing, including without limitation any portion of $2,395,000 PTP
receivable described in Section 6.3 hereof, shall not be included in the calculation of the
Purchase Shares to be issued to the Sellers pursuant to this Section 2.1(c).

The Purchaser Shares issued to Sellers will contain customary legends with respect to applicable
restrictions under securities Laws, and such other legends as are required under the terms of the
Stockholders Agreement.

2.5 hereof and Schedule EO hereto; and

The Closing Date Cash Payment, the principal amounts of the Initial Note and the Working
Capital Notes, the Promissory Note(s), the Purchaser Shares, any Earn-Out Payments, and the
cancellation of the Initial Note shall be referred to collectively as the “Purchase Price.”

funds to an account designated by such Seller (such account to be designated at least two (2)

Note.

2.3 Determination of Net Worth. 

(a) Determination of Estimated Net Worth. Not later than two (2), nor more than five
(5), Business Days prior to the Closing Date, the Company and Sellers shall prepare and deliver to
Purchaser a certificate certifying the Company’s and Sellers’ good faith estimate of the Net Worth
of the Company as of the Closing Date (“Estimated Net Worth”), and including an estimated
unaudited balance sheet of Company as of the Closing Date (“Estimated Closing Date Balance
Sheet”), provided that such balance sheet shall not include footnotes and customary year-end
adjustments. The form of certificate delivered pursuant to this Section 2.3(a) and
acceptable to the Purchaser and the Sellers is referred to herein as the “Closing Payment
Certificate.” The Closing Payment Certificate shall be used to calculate any adjustments to
the first payment under the Promissory Notes in accordance with Section 2.1(b)(i).

(b) Determination of Actual Net Worth. Within sixty (60) calendar days after the
Closing Date, Purchaser will prepare and deliver to Sellers a certificate, signed by Purchaser,
certifying Purchaser’s determination of the actual Net Worth as of the Closing Date, and
identifying any adjustments to the Purchase Price (with such adjustment to be made to the second
payment under the Promissory Notes), as a result of such amounts being less than or greater than
the amounts set forth on the Closing Payment Certificate. If Sellers do not object to Purchaser’s
certificate within thirty (30) calendar days after receipt, or accepts such certificate during
such thirty (30) calendar day period, the Purchase Price shall be adjusted as set forth in
Purchaser’s certificate, and the second payment due the Sellers under the Promissory Notes shall
be adjusted accordingly as the means by which the Purchase Price may be adjusted. If Sellers
object to the Purchaser’s certificate, Sellers shall notify Purchaser in writing of such objection
within thirty (30) calendar days after Sellers’ receipt thereof (such notice setting forth in
reasonable detail the basis for such objection). During such thirty (30) day period, Purchaser
shall permit Sellers and/or any accountant engaged by Sellers at their sole discretion and cost,
access to such work papers, information and supporting documentation relating to the preparation
of Purchaser’s certificate, as may be reasonably requested by Sellers and/or their accountants to
permit Sellers and/or their accountants to review in detail the manner in which Purchaser’s
certificate was prepared. Purchaser and Sellers shall thereafter negotiate in good faith to
resolve any such objections. If Purchaser and Sellers are unable to resolve all of such
differences within twenty (20) calendar days of Purchaser’s receipt of Sellers’ objections, the
items in dispute may be referred by any party for determination as promptly as practicable to the
Independent Accounting Firm, which shall be jointly engaged by Purchaser, on the one hand, and
Sellers, on the other hand, pursuant to an engagement letter in customary form which each of
Purchaser and Sellers shall execute; provided, however, that such engagement letter shall
specifically provide that the Independent Accounting Firm owes fiduciary duties to Sellers and
Purchaser. If PriceWaterhouseCoopers is unable to serve as the Independent Accounting Firm, and
Purchaser and Sellers have failed to reach agreement on a replacement Independent Accounting Firm
within ten (10) calendar days following the termination of the twenty (20) calendar-day period
referred to in the immediately preceding sentence, then Sellers and Purchaser shall cooperate in
causing a replacement Independent Accounting Firm to be selected by the American Arbitration
Association. At the time that the Independent Accounting Firm or any replacement Independent
Accounting Firm is selected, Sellers and Purchaser shall represent and warrant to each other that
the Independent Accounting Firm or replacement Independent Accounting Firm, as applicable, that
has been selected, does not have and has not had a business relationship with any of the Sellers,
Company or Purchaser or any Affiliate of the Sellers, Company or Purchaser within the past three
(3) years. The Independent Accounting Firm shall prescribe procedures for resolving the disputed
items and in all events shall make a written determination, with respect to such disputed items
only, whether and to what extent, if any, the Purchaser’s certificate and the accompanying
calculations of the Net Worth and at Closing require adjustment based on the terms and conditions
of this Agreement (the “Determination”). The Determination shall be based solely on
presentations with respect to such disputed items by Purchaser and Sellers to the Independent
Accounting Firm and not on the Independent Accounting Firm’s independent review; provided, that
such presentations shall be deemed to include, without limitation, any work papers, records,
accounts or similar materials delivered to the Independent Accounting Firm by Purchaser or Sellers
in connection with such presentations and any materials delivered to the Independent Accounting
Firm in response to requests by the Independent Accounting Firm. Each of Purchaser and Sellers
shall use its Reasonable Best Efforts to make its presentation as promptly as practicable
following submission to the Independent Accounting Firm of the disputed items, and each such party
shall be entitled, as part of its presentation, to respond to the presentation of the other party
and any question and requests of the Independent Accounting Firm. Purchaser and Sellers shall
instruct the Independent Accounting Firm to deliver the Determination to Purchaser and Sellers no
later than thirty (30) calendar days following the date on which the disputed items are referred
to the Independent Accounting Firm. In deciding any matter, the Independent Accounting Firm
(i) shall be bound by the provisions of this Section 2.3(b), (ii) may not assign a value
to any item greater than the greatest value for such item claimed by either Purchaser or Sellers
or less than the smallest value for such item claimed by Purchaser or Sellers, and (iii) shall be
bound by the express terms, conditions and covenants set forth in this Agreement, including the
definition of Net Worth contained herein. In the absence of fraud or manifest error, the
Determination shall be conclusive and binding upon Purchaser and Sellers. The Independent
Accounting Firm shall consider only those items and amounts in the Purchaser’s certificate which
Purchaser and Sellers were unable to resolve. All fees and expenses of the Independent Accounting
Firm incurred in connection with any dispute over Purchaser’s certificate shall be borne by the
parties based on the percentage which the portion of the contested amount not awarded to each
party bears to the amount actually contested by such party.

2.4 Adjustment to Purchase Price. The Net Worth amount determined in accordance with
Section 2.3(b) (the “Actual Net Worth”) shall be used to calculate post-Closing
adjustment to the Purchase Price through adjustment to the second payment due Sellers under the
Promissory Notes as follows:

(i) if Actual Net Worth is less than Estimated Net Worth (i.e., if Actual Net Worth is a
greater negative number than Estimated Net Worth), the second payment under the Promissory Notes
shall be reduced by the difference between the Actual Net Worth and Estimated Net Worth;

(ii) if Actual Net Worth is greater than Estimated Net Worth and less than Target Net Worth
(i.e., if Actual Net Worth is a lesser negative number than Estimated Net Worth and a greater
negative number than Target Net Worth), the second payment under the Promissory Notes shall be
increased by the difference between Actual Net Worth and Estimated Net Worth;

Plan will become a multiple employer plan with respect to Company immediately after the Closing
Date.

result in the payment of any amount that by operation of Code Section 280(G) or 162(m) would not

former employees of Company beyond their termination of employment (other than coverage mandated
by law, which is paid solely by such employees); and (ii) there are no reserves, assets, surplus
or prepaid premiums under any such plan.

(i) Except as disclosed on Schedule 3.19(i), the consummation of the transactions
contemplated by this Agreement and the other Transaction Documents will not: (i) entitle any

(ii) accelerate the time of payment or vesting, or increase the amount of any compensation due, or
in respect of, any individual; (iii) result in or satisfy a condition to the payment of
compensation that would, in combination with any other payment, result in an “excess parachute

any representation or warranty, until the aggregate amount of Losses incurred by the Purchaser
Parties or Seller Parties, as the case may be, exceeds Seventy-Five Thousand Dollars ($75,000)
(the “Basket Amount”), and Sellers or the Purchaser (as applicable) shall only be liable
for the amount of all such Losses that exceeds the Basket Amount; provided that no Losses for any

included in the calculation of the Basket Amount unless the Losses related to that particular
breach, failure or matter exceeds Five Thousand Dollars ($5,000 (the “Minimum Claim
Size”)).

(b) Maximum Aggregate Amount. Except as otherwise expressly provided in this
Section 8, the maximum aggregate amount of indemnification payments under this
Section 8 in connection with the inaccuracy in or breach of any representation or warranty
to which the Purchaser Parties or Seller Parties shall be entitled to receive, upon the triggering

8.5 Satisfaction of Sellers’ Indemnity Obligations. The indemnification obligations of
the Sellers to the Purchaser, the amount of which has been finally determined under this
Section 8 or agreed to by the Sellers, shall be satisfied as follows:

(a) first, by either:

(i) set-off against, and cancellation of, a number of Holdback Shares equal to the quotient
obtained by dividing (i) the amount of Losses finally determined to be owed by the Sellers, or
agreed to by the Sellers, pursuant to their indemnification obligations hereunder, by (ii) the
volume-weighted average closing price of the Purchaser common stock (as quoted on the OTC Bulletin
Board or such other exchange or quotation system as the Purchaser common stock shall then be
traded) for the twenty (20) trading days immediately preceding the date on which such amount of
Losses is finally determined or agreed to; or

(ii) by set-off against any Earn-Out Payment owed by Purchaser; or

(b) second, by set-off against amounts owed by the Purchaser under the Promissory Notes in
accordance with the terms thereof; or

(c) third, by direct monetary payment by the Sellers to the Purchaser.

The indemnification remedy or remedies sought by the Purchaser under Section 8.5(a)(i)-(ii)
shall be at the option and in the discretion of the Purchaser; provided, that the Purchaser
shall have exhausted recovery pursuant to Section 8.5(a) prior to seeking recovery pursuant
to Section 8.5(b), and shall have exhausted recovery pursuant to Section 8.5(a) and
(b) prior to seeking recovery pursuant to Section 8.5(c). With respect to recovery
by the Purchaser against the Promissory Notes, Holdback Shares and/or Earn-Out Payments, the
Purchaser’s recovery shall, to the extent possible, be made on the basis of each Seller’s Pro Rata
Share of the amount owed to the Purchaser.

With respect to the Holdback Shares, the Sellers hereby grant a first priority security interest
in, and pledge and instruct Purchaser to set aside and hold, certificates representing the Holdback
Shares issued pursuant to this Agreement in order to provide security for the Sellers
indemnification obligations hereunder.

8.6  Defense of Claims. In the case of any claim for indemnification under
Section 8.1 or 8.2 arising from a request for information, audit or claim of a
third party (including the IRS or any Governmental Authority), an indemnified party shall give
prompt written notice and, subject to the following sentence, in no case later than ten (10)
Business Days after the indemnified party’s receipt of notice of such request for information,
audit or claim, to the indemnifying party of any request for information, audit, claim, suit or
demand of which such indemnified party has Knowledge and as to which it may request indemnification
hereunder. The failure to give such notice shall not, however, relieve the indemnifying party of
its indemnification obligations except to the extent that the indemnifying party is actually harmed
thereby. The indemnifying party shall have the right to defend and to direct the defense against
any such request for information, audit, claim, suit or demand, in its name and at its expense, and
with counsel selected by the indemnifying party unless such claim, suit or demand seeks an
injunction or other equitable relief against the indemnified party; provided, however, the
indemnifying party shall not have the right to defend or direct the defense of any such request for
information, audit, claim, suit or demand if it refuses to acknowledge fully its obligations to the
indemnified party or contests, in whole or in part, its indemnification obligations therefor. If
the indemnifying party elects, and is entitled, to compromise or defend such request for
information, audit or claim, it shall within thirty (30) days (or sooner, if the nature of the
claim so requires) notify the indemnified party of its intent to do so, and the indemnified party
shall, at the request and expense of the indemnifying party, cooperate in the defense of such
request for information, audit, claim, suit or demand. If the indemnifying party elects not to
compromise or defend such request for information, audit or claim, fails to notify the indemnified
party of its election as herein provided or refuses to acknowledge or contests its obligation to
indemnify under this Agreement, the indemnified party may pay, compromise or defend such request
for information, audit or claim. Except as set forth in the immediately preceding sentence, the
indemnifying party shall have no indemnification obligations with respect to any such request for
information, audit, claim, suit or demand which shall be settled by the indemnified party without
the prior written consent of the indemnifying party (which consent shall not be unreasonably
withheld or delayed); provided, however, that notwithstanding the foregoing, the
indemnified party shall not be required to refrain from paying any claim which has matured by a
court judgment or decree, unless an appeal is duly taken therefrom and exercise thereof has been
stayed, nor shall it be required to refrain from paying any claim where the delay in paying such
claim would result in the foreclosure of a lien upon any of the property or assets then held by the
indemnified party or where any delay in payment would cause the indemnified party material economic
loss. The indemnifying party’s right to direct the defense shall include the right to compromise
or enter into an agreement settling any request for information, audit or claim by a third party;
provided that no such compromise or settlement shall obligate the indemnified party to
agree to any settlement which requires the taking of any action by the indemnified party other than
the delivery of a release, except with the consent of the indemnified party (which consent shall
not be unreasonably withheld or delayed). Notwithstanding the indemnifying party’s right to
compromise or settle in accordance with the immediately preceding sentence, the indemnifying party
may not settle or compromise any request for information, audit or claim over the commercially
reasonable objection of the indemnified party; provided, however, that consent by the
indemnified party to settlement or compromise shall not be unreasonably withheld or delayed. The
indemnified party shall have the right to participate in the defense of any request for
information, audit, claim, suit or demand with counsel selected by it subject to the indemnifying
party’s right to direct the defense. The fees and disbursements of such counsel shall be at the
expense of the indemnified party; provided, however, that, in the case of any request for
information, audit, claim, suit or demand which seeks injunctive or other equitable relief against
the indemnified party, the fees and disbursements of such counsel shall be at the expense of the
indemnifying party.

8.7 Non-Third Party Claims. Any claim which does not result in a third party claim
shall be asserted by a written notice to the other party or parties and shall be identified as a
“DIRECT INDEMNITY CLAIM NOTICE.” The recipient of such notice shall have a period of thirty (30)
days after receipt of such notice within which to respond thereto. During such thirty (30) day
period, the recipient shall have the right to cure any applicable breach of this Agreement. If the
recipient does not respond within such thirty (30) days, the recipient shall be deemed to have
accepted responsibility for the Losses set forth in such notice and shall have no further right to
contest the validity of such notice. If the recipient responds within such thirty (30) days after
the receipt of the notice and rejects such claim in whole or in part, the party delivering shall be
free to pursue such remedies as may be available to it under this Section 8.

8.8 Further Limitations Upon Seller Parties’ or Purchaser Parties’ Indemnification
Obligations. The indemnification obligations of the Seller Parties to the Purchaser Parties,
or the Purchaser Parties to the Seller Parties, shall be net of any tax benefit actually realized
in connection with a liability, damage, expense or loss indemnified hereunder, but after giving
effect to any tax which may be required to be paid on the indemnification payment. A tax
adjustment indemnified hereunder which involved only a change in the year in which an amount is
includible in income or deductible and no other loss shall be indemnified only to the extent of the
interest, additions to tax and penalties resulting from such adjustment. In addition, the Seller
Parties shall not be required to indemnify the Purchaser Parties for any claim to the extent that
the Purchaser or the Company receives insurance proceeds with respect to such claim based on
insurance policies that have been maintained by the Purchaser or the Company and are paid current
and in place at the Closing Date; provided, that nothing herein shall obligate the
Purchaser or the Company to seek any insurance or to make any insurance claim following the
Closing.

8.9 Liability of the Company. Purchaser shall not after the Closing make any claim
against Company in respect of any representation, warranty, covenant or any other obligation of
Company to Purchaser hereunder or under any other Transaction Document to which Company is a party.

8.10 Tax Treatment. Unless otherwise required by applicable law, all indemnification
payments shall constitute adjustments to the Purchase Price for all Tax purposes, and no party
shall take any position inconsistent with such characterization.

8.11 No Waiver. The foregoing indemnification provisions in this Section 8
(including without limitation the provisions of Section 8.3 and Section 8.4) do
not (a) waive or affect any claims for fraud or willful misconduct to which a party hereto may be
entitled, or shall relieve or limit the liability of any party from any liability arising out of or
resulting from fraud or willful misconduct in connection with the transactions contemplated by this
Agreement or in connection with the delivery of any of the documents referred to herein and
(b) waive or affect any equitable remedies to which a party may be entitled.

8.12 No Right of Contribution Against Company. Sellers shall have no right to seek
contribution from Company with respect to all or any part of any of a Seller’s indemnification
obligations under this Section 8.

8.13 Exclusive Remedy. Except with respect to fraud or willful misconduct, the
remedies provided for in this Section 8 shall be the sole and exclusive remedies of the
parties hereto and their Affiliates and their respective shareholders, trustees, officers,
directors, employees, agents, representatives, successors and assigns for any breach of or
inaccuracy in any representation, warranty or covenant contained in this Agreement. The foregoing
shall not limit any party’s rights to seek equitable remedies.

9. TERMINATION.

9.1 Termination. This Agreement may be terminated at any time prior to the Closing Date:

(g) by Purchaser, (i) if the Company shall have instituted any proceeding (A) seeking a
declaration or entailing a finding that the Company is insolvent under any law relating to
bankruptcy, insolvency, relief of debtors or protection of creditors, or any other similar law now
or hereafter in effect, or (B) seeking appointment of a receiver, trustee, liquidator, assignee,
sequestrator or other custodian for the Company or for all or any substantial part of the
Company’s property, or (ii) a proceeding shall have been instituted by any third party in respect
of the Company (A) seeking a declaration or entailing a finding that the Company is insolvent
under any law relating to bankruptcy, insolvency, relief of debtors or protection of creditors, or
any other similar law now or hereafter in effect, or (B) seeking appointment of a receiver,
trustee, liquidator, assignee, sequestrator or other custodian for the Company or for all or any
substantial part of the Company’s property; or

(h) by either Purchaser on the one hand or Sellers and Company on the other hand, if an
order, decree, ruling, judgment or injunction has been entered by any Governmental Authority of
competent jurisdiction permanently restraining, enjoining or otherwise limiting or prohibiting the
consummation of the transactions contemplated by this Agreement and such order, decree, ruling,
judgment or injunction has become final and non-appealable.

9.2 Effect of Termination. If this Agreement is terminated as provided in
Section 9.1, then all further obligations under this Agreement shall terminate and no party
hereto shall have any liability in respect of the termination of this Agreement; provided,
however, that the confidentiality obligations of Purchaser, Sellers and Company described
in Section 5.7 will survive any such termination; provided further that no
such termination will relieve Purchaser, on the one hand, or Sellers or Company, on the other hand,
from liability for (i) any willful breach of any representation or warranty made by such party or
parties hereunder, (ii) any breach of any covenant or agreement of such party or parties hereunder,
or (iii) any fraud or willful misconduct, in each case described in clauses (i) through (iii)
above, prior to such termination, and in the event of such breach the parties hereto shall be
entitled to exercise any and all remedies available under law or equity in accordance with this
Agreement. Notwithstanding anything herein to the contrary, in the event of termination of this
Agreement for any reason, Purchaser shall have all rights and remedies under and pursuant to the
Initial Note and the Working Capital Notes.

(a) Notwithstanding the foregoing Section 9.2(a), upon the occurrence of a Post-Signing
Event, the Purchaser may either (x) terminate this Agreement after the applicable cure period,
with the only obligation of the Company and/or Sellers to Purchaser the rights and remedies under
and pursuant to the Initial Note and the Working Capital Notes; or (y) waive, in writing, the
Post-Signing Event as a cause for termination and permit the Company and the Sellers to update the
Disclosure Schedule.

10. POST CLOSING MATTERS. Following the Closing Date, the parties agree as follows:

10.1 Cooperation. In case at any time after the Closing any further action is
necessary to carry out the purposes of this Agreement each of the parties will take such further
action (including the execution and delivery of such further instruments and documents including
but not limited to any amendments and/or restatements to or of the Stockholders Agreement) as any
other party reasonably may request, all at the sole cost and expense of the requesting party
(unless the requesting party is entitled to indemnification therefor under Section 8
hereof). Sellers acknowledge and agree that from and after the Closing Purchaser will be entitled
to possession of and Sellers will provide to Purchaser all documents, books, records (including Tax
records), agreements, corporate minute books and financial data of any sort relating to Company.

10.2 Litigation Support. In the event and for so long as any party actively is
contesting or defending against any action, suit, proceeding, hearing, investigation, charge,
complaint, claim, or demand in connection with (i) any transaction contemplated under this
Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction that existed on or prior to the
Closing Date involving Company, each of the other parties will cooperate with such party and such
party’s counsel in the contest or defense, make available their personnel, and provide such
testimony and access to their books and records as shall be reasonably necessary in connection with
the contest or defense, all at the sole cost and expense of the contesting or defending party
(unless the contesting or defending party is entitled to indemnification therefor under
Section 8 hereof).

10.3 Transition; Standard Employee NDAs. Neither Seller will take any action that is
designed or intended to have the effect of discouraging any lessor, licensor, customer, supplier,
or other business associate of Company from maintaining the same business relationships with
Company after the Closing as it maintained with Company prior to the Closing. Each Seller will
refer all customer inquiries relating to the business of Company to Company from and after the
Closing. In addition, after the Closing, Purchaser and Sellers shall cause Company, and Sellers
shall use Reasonable Best Efforts, and cooperate with Purchaser, to cause each employee of Company
who will continue as an employee following the Closing to enter into Purchaser’s Standard
Non-Disclosure and Assignment of Inventions Agreements, substantially in the form of Exhibit
B hereto (the “Standard Employee NDA(s)”).

10.4 Confidentiality. Each Seller will treat and hold as confidential all of the
Confidential Information, refrain from using any of the Confidential Information except in
connection with this Agreement, and deliver promptly to Purchaser or destroy, at the request and
option of Purchaser, all tangible embodiments (and all copies) of the Confidential Information
which are in Seller’s possession. In the event that any Seller is requested or required (by oral
question or request for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand, or similar process) to disclose any Confidential Information, such
Seller will notify Purchaser promptly of the request or requirement so that Purchaser may seek an
appropriate protective order or waive compliance with the provisions of this Section 10.4.
If, in the absence of a protective order or the receipt of a waiver hereunder, a Seller is, on the
advice of counsel, compelled to disclose any Confidential Information to any tribunal or else stand
liable for contempt, such Seller may disclose the Confidential Information to the tribunal;
provided, however, that such Seller shall use its best efforts to obtain, at the request of
Purchaser, an order or other assurance that confidential treatment will be accorded to such portion
of the Confidential Information required to be disclosed as Purchaser shall designate. The
foregoing provisions shall not apply to any Confidential Information, which is generally available
to the public immediately prior to the time of disclosure.

10.5 Books and Records. Each party agrees that it will reasonably cooperate with and
make available (or cause to be made available) to the other party, during normal business hours,
all books and records, information and employees (without substantial disruption of employment)
retained, remaining in existence or continuing to be employed after the Closing Date which are
necessary or useful in connection with any Tax inquiry, audit, or dispute, any litigation or
investigation or any other matter requiring any such books and records, information or employees
for any reasonable business purpose (a “Permitted Use”). The party requesting any such
books and records, information or employees shall bear all of the out-of-pocket costs and expenses
reasonably incurred in connection with providing such books and records, information or employees.
All information received pursuant to this Section 10.5 shall be kept confidential pursuant
to Section 10.4 (which shall continue to apply to this extent following the Closing Date)
by the party receiving it, except to the extent that disclosure is reasonably necessary in
connection with any Permitted Use.

10.6 Cooperation and Records Retention. Company, Sellers and Purchaser each shall
(i) provide the other with such assistance as may reasonably be requested by either of them in
connection with the preparation of any Tax Return, audit, or other examination by any taxing
authority or judicial or administrative proceedings relating to liability for any Taxes;
(ii) retain and provide the other with any records or other information that may be relevant to
such Tax Return, audit or examination, proceeding or determination; (iii) provide the other with
any final determination of any such audit or examination, proceeding, or determination that affects
any amount required to be shown on any Tax Return of the other for any period; and (iv) cooperate
with respect to closing the books of Company and filing a tax return for Company as of the Closing
Date. The party requesting any such assistance or information shall bear all of the out-of-pocket
costs and expenses reasonably incurred in connection with providing such assistance or information.

10.7 Preemptive Rights. Subject to the terms and conditions of this
Section 10.7 and applicable securities laws, if, during the eighteen (18) month period
immediately following the Closing, the Purchaser proposes to offer or sell any New Securities, the
Company shall first offer a pro-rata share of such New Securities to each Seller.

(a) The Purchaser shall give notice (the “Offer Notice”) to each Seller, stating
(i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities
to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New
Securities.

(b) By notification to the Purchaser within twenty (20) days after the Offer Notice is given,
each Seller may elect to purchase or otherwise acquire, at the price and on the terms specified in
the Offer Notice, up to that portion of such New Securities set aside by the Purchaser’s board of
directors for purchase by existing investors which equals the proportion that the Common Stock
issued and held by such Seller or issuable (directly or indirectly) upon conversion and/or
exercise, as applicable, of any Derivative Securities held by such Seller bears to the total
Purchaser Common Stock issued and held or issuable (directly or indirectly) upon conversion and/or
exercise, as applicable, of any Derivative Securities outstanding.

(c) If all New Securities referred to in the Offer Notice eligible to be purchased by the
Sellers pursuant to this Section 10.7 are not elected to be purchased or acquired by the
Sellers as provided in Section 10.7(b), the Purchaser may offer and sell the remaining
unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and
upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the
Purchaser does not enter into an agreement for the sale of the New Securities within such period,
or if such agreement is not consummated within sixty (60) days of the execution thereof, the right
provided hereunder shall be deemed to be revived and such New Securities shall not be offered
unless first reoffered to the Sellers in accordance with this Section 10.7.

(d) The right of first offer in this Section 10.7 shall not be applicable to Exempted
Securities.

(e) The right of first offer set forth in this Section 10.7 shall terminate with
respect to any Seller who fails to purchase, in any transaction subject to this
Section 10.7, all of such Seller’s pro rata amount of the New Securities allocated (or, if
less than such Seller’s pro rata amount is offered by the Purchaser, such lesser amount so
offered) to such Seller pursuant to this Section 10.7.

10.8 Registration Statement.

(a) Subject to receipt of necessary information from the Sellers, including completion of a
questionnaire customary in form and substance for such purpose, the Purchaser will, in no event
later than six (6) months following the Closing Date, prepare and file with the SEC a Registration
Statement on Form S-3 (or, if the Purchaser is ineligible to utilize such form, on Form S-1) to
permit a public offering and resale of the Purchaser Shares under the Securities Act on a
continuous basis under Rule 415 under the Securities Act. The Purchaser acknowledges that the
plan of distribution contemplated by such Registration Statement may include offers and sales
through underwriters or agents, offers and sales directly to investors, block trades and such
other methods of offer and sale as a Seller may request. The Purchaser will use reasonable
commercial efforts to cause the Registration Statement to be declared effective by the SEC within
120 days following the filing thereof. The Purchaser will use reasonable commercial efforts to
cause such Registration Statement to remain effective until such time as all of the shares of
Purchaser Common Stock designated thereunder are sold.

(b) The Purchaser shall not be required to effect more than one (1) registration pursuant to
the first sentence of paragraph (a) above.

(c) The expenses of the registration pursuant to this Section 10.8 shall be paid by
the Purchaser.

(d) The Purchaser may delay the filing or effectiveness of any registration statement for a
period of up to 120 days following the date on which the registration statement is due to be filed
in accordance with paragraph (a) above or is eligible to become effective under the Securities
Act, as the case may be, if at such time: (i) the Purchaser is engaged, or has fixed plans to
engage within 60 days of such time, in a firm commitment underwritten public offering, or (ii) the
Purchaser furnishes to the Sellers a certificate signed by a senior executive officer of the
Purchaser stating that the Purchaser is engaged in any other activity which, in the good faith
determination of the Purchaser’s Board of Directors, is a material non-public event which would be
adversely affected by the registration to the material detriment of the Purchaser;
provided, however, that the Purchaser may not utilize the right set forth in this
paragraph (d) more than once in any 12-month period.

(e) In connection with any registration pursuant to this Section 10.8, Purchaser
shall, as promptly as practicable:

(i) prepare and file with the SEC such amendments and supplements to the Registration
Statement or prospectus as may be necessary to comply with the provisions of the Securities Act
with respect to the sale or disposition of all securities covered by the Registration Statement;

(ii) furnish to the Sellers copies of the preliminary and final prospectus and other documents
in such number as they may reasonably request in order to facilitate the disposition of Purchaser
Shares owned by them;

(iii) use all reasonable efforts to register and qualify the Purchaser Shares covered by such
registration statement under such other securities or blue sky laws of the jurisdictions as shall
be required by applicable Law, provided that the Purchaser shall not be required to qualify
to do business or to file a general consent to service of process in any such states or
jurisdictions;

(iv) in the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement, in customary form, with the managing underwriter of such offering;
and

(v) notify each holder of Purchaser Shares covered by such Registration Statement at any time
when a prospectus relating thereto is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such registration statement
includes an untrue statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing.

10.9 Tax Matters.

(a) Periods Ending on or Before the Closing Date. Sellers shall prepare or cause to
be prepared and file or cause to be filed all Tax Returns for Company for all periods ending on or
prior to the Closing Date which are filed after the Closing Date. Any Tax Returns filed pursuant
hereto must be consistent with the calculation of Net Worth. No later than twenty (20) days prior
to filing, Sellers shall deliver to Purchaser all such Tax Returns and any related work papers and
shall permit Purchaser to review and comment on each such Tax Return and shall make such revisions
to such Tax Returns as are reasonably requested by Purchaser. Sellers shall timely pay to the
appropriate taxing authority any Taxes of Company with respect to such periods to the extent such
Taxes were not included as a liability in the calculation of Actual Net Worth. The costs, fees
and expenses related to the preparation of such Tax Returns shall be estimated and accrued as a
liability of Company for purposes of calculating Net Worth and shall be payable by Company.

(b) Periods Beginning Before and Ending After the Closing Date. To the extent that
any Tax Returns of Company relate to any Tax periods which begin before the Closing Date and end
after the Closing Date, Purchaser shall prepare or cause to be prepared in a manner consistent
with the prior Tax Returns of Company and file or cause to be filed any such Tax Returns.
Purchaser shall permit the Sellers to review and comment on each such Tax Return described in the
preceding sentence at least twenty (20) days prior to filing such Tax Returns and shall make such
revisions to such Tax Returns as are reasonably requested by the Sellers. Any Taxes of Company
with respect to the portion of such period ending on the Closing Date, to the extent such Taxes
were not included as a liability in the calculation of Actual Net Worth, shall be paid in cash by
the Sellers. The costs, fees and expenses related to the preparation of such Tax Returns shall be
paid by Purchaser or Company. For purposes of this Section 10.9(b), in the case of any
Taxes that are imposed on a periodic basis and are payable for a taxable period that includes but
does not end on the Closing Date, the portion of such Tax which relates to the portion of such
taxable period ending on the Closing Date shall (i) in the case of any Taxes other than Taxes
based upon or related to income or receipts, be deemed to be the amount of such Tax for the entire
taxable period multiplied by a fraction the numerator of which is the number of days in the
taxable period ending on the Closing Date and the denominator of which is the number of days in
the entire taxable period, and (ii) in the case of any Tax based upon or related to income or
receipts be deemed equal to the amount which would be payable if the relevant taxable period ended
on the Closing Date. Any credits relating to a taxable period that begins before and ends after
the Closing Date shall be taken into account as though the relevant taxable period ended on the
Closing Date. All determinations necessary to give effect to the foregoing allocations shall be
made in a manner consistent with prior practice of Company.

(c) Tax Sharing Agreements. All Tax Sharing Agreements or similar agreements with
respect to or involving Company shall, unless otherwise agreed to by Purchaser, be terminated as
of the Closing Date and, after the Closing Date, Company shall not be bound thereby or have any
liability thereunder.

(d) Further Efforts. The Purchaser and the Sellers further agree, upon request, to
use their Reasonable Best Efforts (without expense to the Sellers) to obtain any certificate or
other document from any Governmental Authority or any other Person as may be necessary to
mitigate, reduce or eliminate any Tax that could be imposed (including, without limitation, with
respect to the transactions contemplated hereby).

10.10 338(h)(10) Election. The Purchaser and the Sellers shall jointly make a timely
election provided for by Section 338(h)(10) of the Code and Section 1.338(h)(10) of the
Treasury regulations (and any comparable election under state or local laws) (collectively, the
“Election”) with respect to the acquisition of the Company Common Stock. The purchase
price for the Company Common Stock shall be allocated among the assets of the Company based upon
the fair market value of the assets of the Company at the time of Closing for purposes of
completing all forms of any nature necessary to effectuate the Election (including, but not limited
to, Internal Revenue Service Form 8023, Corporate Qualified Stock Purchase, Form 8883 and any
similar forms under applicable state or local law) (the “Section 338 Forms”) in accordance
with applicable U.S. Treasury regulations. Within one hundred twenty (120) days after the Closing,
Purchaser will delivery to the Sellers a statement containing the Purchaser’s allocation of the
purchase price for the Company Common Stock among the assets of the Company (the (“Asset
Allocation Statement”). The Asset Allocation Statement will be prepared in accordance with
Sections 338 and 1060 of the Code and any comparable provisions of state, local or
foreign Law, as appropriate. The Purchaser shall permit the Sellers to review and comment on such
Asset Allocation Statement at least ten (10) days prior to filing such Asset Allocation Statement,
but shall have no obligation to make any changes requested by the Sellers. Based on allocation set
forth in the Asset Allocation Statement, the Purchaser and the Sellers shall jointly prepare the
Section 338 Forms and the Purchaser and the Company shall execute and deliver the Section 338 Forms
to one another for filing. The Company and the Purchaser shall duly and timely file the
Section 338 Forms in accordance with applicable tax laws and in accordance with this Agreement.
The Company and the Purchaser shall report the acquisition by the Purchaser of the Company Common
Stock pursuant to this Agreement consistent with the Election and shall take no position contrary
thereto or inconsistent therewith in any Tax Return, any discussion with or proceeding before any
taxing authority, or otherwise. The Purchaser agrees to provide the Sellers written instructions
in accordance with applicable Law as to what is necessary to file a timely, valid Election. The
Sellers and the Company agree to comply with such reasonable instructions. The Purchaser on the
one hand and the Sellers on the other hand shall promptly inform each other of any challenge by any
Tax authority to any allocation made pursuant to this Section 10.10; provided,
however, that the Purchaser shall be fully responsible for conducting and managing such challenge.

10.11 Seller Guarantees. Following the Closing, the Purchaser agrees to use
commercially reasonable to, and commercially reasonable efforts to cause the Company to, remove any
personal guarantee by the Sellers with respect to indebtedness of the Company outstanding as of the
Closing Date.

11. EXPENSES. Except as otherwise expressly set forth elsewhere in this Agreement, Purchaser
shall bear its own legal and other fees and expenses incurred in connection with its negotiating,
executing and performing this Agreement, including, without limitation, any related broker’s or
finder’s fees. Company and Sellers shall bear their respective legal and other fees and expenses
incurred in connection with their negotiating, executing and performing this Agreement, including,
without limitation, any related broker’s or finder’s fees (except as otherwise expressly set forth
herein with respect to any such fees owed to Excell or except as otherwise included as a liability
for in the determination of Actual Net Worth), for periods on or before the Closing Date. Sellers
shall bear their own legal and other fees and expenses incurred in connection with this Agreement
after the Closing, including, without limitation, any related broker’s or finder’s fees, subject to
the provisions of this Agreement. Sellers shall pay all applicable Taxes, if any, which are due as
a result of the transfer of the Company Common Stock in accordance herewith.

12. FURTHER ASSURANCES. From time to time at or after the Closing Date, at the request of the
other, Purchaser and Sellers each will execute and deliver such other instruments of conveyance,
assignment, transfer and delivery and take such actions as the other reasonably may request in
order to consummate, complete and carry out the transactions contemplated hereby, including the
execution and delivery of such instruments and agreements as may be reasonably necessary or
advisable to fully effect the transfer of the Company Common Stock to Purchaser.

13. AMENDMENT; BENEFIT AND ASSIGNABILITY. This Agreement may be amended only by the execution
and delivery of a written instrument by or on behalf of the Company, Sellers and Purchaser. This
Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns, and no other person or entity shall have any right
(whether third party beneficiary or otherwise) hereunder. Sellers acknowledge and agree that
Purchaser may merge with or be acquired by another business entity after Closing, and any successor
business entity will have all of the rights and remedies of Purchaser hereunder. This Agreement
may not be assigned by any party without the prior written consent of the other parties;
provided, however, that Purchaser may assign all or any portion of this Agreement
to any Affiliate of Purchaser, provided that Purchaser shall remain obligated for the payment of
the Purchase Price and the performance of this Agreement.
