                                        INDEMNIFICATION AGREEMENT

         This Indemnification Agreement (this "AGREEMENT") is made and entered
into this __ day of June, 2006, by and between Optium Corporation, a Delaware
corporation (the "COMPANY," which term shall include, where appropriate, any
Entity (as hereinafter defined) controlled, directly or indirectly, by the
Company) and _________________ (the "INDEMNITEE"):

         WHEREAS, it is essential to the Company that it be able to retain and
attract as directors and executive officers the most capable persons available;

         WHEREAS, increased corporate litigation has subjected directors and
executive officers to litigation risks and expenses, and the limitations on the
availability of directors and officers liability insurance have made it
increasingly difficult for the Company to attract and retain such persons;

         WHEREAS, the Company's By-laws, as amended from time to time (the
"BY-LAWS") require it to indemnify its directors and executive officers to the
fullest extent permitted by law and permit it to make other indemnification
arrangements and agreements;

         WHEREAS, the Company desires to provide Indemnitee with specific
contractual assurance of Indemnitee's rights to full indemnification against
litigation risks and expenses (regardless, among other things, of any amendment
to or revocation of the Company's Fifth Amended and Restated Certificate of
Incorporation, as amended from time to time (the "CERTIFICATE OF INCORPORATION")
or By-laws or any change in the ownership of the Company or the composition of
its Board of Directors);

         WHEREAS, the Company intends that this Agreement provide Indemnitee
with greater protection than that which is provided by the Company's By-laws;
and

         WHEREAS, Indemnitee is relying upon the rights afforded under this
Agreement in becoming or continuing as a director or executive officer of the
Company.

         NOW, THEREFORE, in consideration of the promises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:

         2. SERVICES OF INDEMNITEE. In consideration of the Company's covenants
and commitments hereunder, Indemnitee agrees to serve or continue to serve as a
director or

<Page>

executive officer of the Company. However, this Agreement shall not impose any
obligation on Indemnitee or the Company to continue Indemnitee's service to the
Company beyond any period otherwise required by law or by other agreements or
commitments of the parties, if any. Indemnitee may at any time and for any
reason resign from such position (subject to any other contractual obligation or
any obligation imposed by operation of law), upon which event the Company shall
have no obligation under this Agreement to continue Indemnitee in such position.
Notwithstanding the forgoing, this Agreement shall continue in force after
Indemnitee has ceased to serve as a director or executive officer of the
Company.

         3. INDEMNITY IN THIRD-PARTY PROCEEDINGS. The Company shall indemnify
Indemnitee in accordance with the provisions of this Section 3 if Indemnitee is,
or is threatened to be made, by reason of Indemnitee's Corporate Status, a party
to or a participant in any Proceeding, other than a Proceeding by or in the
right of the Company to procure a judgment in its favor. Pursuant to this
Section 3, Indemnitee shall be indemnified against all Expenses and Liabilities
actually and reasonably incurred by Indemnitee or on his behalf in connection
with such Proceeding or any claim, issue or matter therein (indemnifiable
Expenses and Liabilities collectively referred herein as "INDEMNIFIABLE
AMOUNTS"), if Indemnitee acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the Company and, in
the case of a criminal Proceeding, had not reasonable cause to believe that his
conduct was unlawful. Indemnitee shall not enter into any settlement in
connection with a Proceeding without the consent of the Company, which shall not
be unreasonably held or delayed.

         4. INDEMNITY IN PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY. The
Company shall indemnify Indemnitee in accordance with the provisions of this
Section 4 if Indemnitee is, or is threatened to be made, by reason of
Indemnitee's Corporate Status, a party to or a participant in any Proceeding by
or in the right of the Company to procure a judgment in its favor. Pursuant to
this Section 4, Indemnitee shall be indemnified against all Expenses actually
and reasonably incurred by him or on his behalf in connection with such
Proceeding or any claim, issue or matter therein, if Indemnitee acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company. No indemnification for Expenses shall be made under
this Section 4 in respect of any claim, issue or matter as to which Indemnitee
shall have been finally adjudged by a court to be liable to the Company, unless
and only to the extent that the Delaware Court of Chancery (the "DELAWARE
CHANCERY COURT") or any court in which the Proceeding was brought shall
determine upon application that, despite the adjudication of liability, but in
view of all the circumstances of the case, Indemnitee is fairly and reasonably
entitled to indemnification for such Expenses as the Delaware Chancery Court or
such other court shall deem proper.

         5. INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY
SUCCESSFUL. If Indemnitee is not wholly successful in such Proceeding but is
successful, on the merits or otherwise, as to one or more but less than all
claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against: (a) all Expenses reasonably incurred by Indemnitee or on
Indemnitee's behalf in connection with each successfully resolved claim, issue
or matter; and (b) any claim, issue or matter related to any such successfully
resolved claim, issue or matter. For purposes of this Agreement, the termination
of any claim, issue or matter in such a Proceeding by dismissal, with or without
prejudice, by reason of settlement, judgment, order or otherwise, shall be
deemed to be a successful result as to such claim, issue or matter.

<Page>

         6. PROCEDURE FOR PAYMENT OF INDEMNIFIABLE AMOUNTS. Indemnitee shall
submit to the Company a written request specifying the Indemnifiable Amounts for
which Indemnitee seeks payment under Sections 3, 4 or 5 of this Agreement and
the basis for the claim. The Company shall pay such Indemnifiable Amounts to
Indemnitee promptly upon receipt of its request. At the request of the Company,
Indemnitee shall furnish such documentation and information as are reasonably
available to Indemnitee and necessary to establish that Indemnitee is entitled
to indemnification hereunder.

         7. INDEMNIFICATION FOR EXPENSES OF A WITNESS. Notwithstanding any other
provision of this Agreement, to the extent that Indemnitee is, by reason of his
Corporate Status, a witness in any Proceeding to which Indemnitee is not a
party, he shall be indemnified against all Expenses actually and reasonably
incurred by him or on his behalf in connection therewith.

         8. EFFECT OF CERTAIN RESOLUTIONS. Neither the settlement or termination
of any Proceeding nor the failure of the Company to award indemnification or to
determine that indemnification is payable shall create a presumption that
Indemnitee is not entitled to indemnification hereunder. In addition, the
termination of any proceeding by judgment, order, settlement, conviction, or
upon a plea of NOLO CONTENDERE or its equivalent shall not create a presumption
that Indemnitee did not act in good faith and in a manner which Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company
or, with respect to any criminal Proceeding, had reasonable cause to believe
that Indemnitee's action was unlawful.

         9. EXCLUSIONS. Notwithstanding any provision in this Agreement to the
contrary, the Company shall not be obligated under this Agreement to make any
indemnity in connection with any claim made against Indemnitee:

            (a) for which payment has actually been made to or on behalf of
            Indemnitee under any insurance policy or other indemnity provision,
            except with respect to any excess beyond the amount paid under any
            insurance policy or other indemnity provisions;

            (b) for an accounting of profits made from the purchase and sale (or
            sale and purchase) by Indemnitee of securities of the Company within
            the meaning of Section 16(b) of the Securities Exchange Act of 1934,
            as amended, or similar provisions of state statutory law or common
            law; or

            (c) for which payment is prohibited by applicable law.

         10. AGREEMENT TO ADVANCE EXPENSES; UNDERTAKING. The Company shall
advance all Expenses incurred by or on behalf of Indemnitee in connection with
any Proceeding, including a Proceeding by or in the right of the Company, in
which Indemnitee is involved by reason of such Indemnitee's Corporate Status
within thirty (30) calendar days after the receipt by the Company of a written
statement from Indemnitee requesting such advance or advances from time to time,
whether prior to or after final disposition of such Proceeding. Advances shall
be unsecured and interest free. Advances shall be made without regard to
Indemnitee's ability to repay the

<Page>

expenses and without regard to Indemnitee's ultimate entitlement to
indemnification under the other provisions of this Agreement. To the extent
required by Delaware law, Indemnitee hereby undertakes to repay any and all of
the amount of indemnifiable Expenses paid to Indemnitee if it is finally
determined by a court of competent jurisdiction that Indemnitee is not entitled
under this Agreement to indemnification with respect to such Expenses. This
undertaking is an unlimited general obligation of Indemnitee.

         11. PROCEDURE FOR ADVANCE PAYMENT OF EXPENSES. Indemnitee shall submit
to the Company a written request specifying the Expenses for which Indemnitee
seeks an advancement under Section 10 of this Agreement, together with
documentation evidencing that Indemnitee has incurred such Expenses (which shall
include invoices received by Indemnitee in connection with such Expenses but, in
the case of invoices in connection with legal services, any reference to legal
work performed or to expenditures made that would cause Indemnitee to waive any
privilege accorded by applicable law shall not be included with the invoice).
Advances under Section 10 shall be made no later than thirty (30) calendar days
after the Company's receipt of such request. If a claim for advancement of
Expenses hereunder by Indemnitee is not paid in full by the Company within
thirty (30) calendar days after receipt by the Company of documentation of
Expenses and the required undertaking, Indemnitee may at any time thereafter
bring suit against the Company to recover the unpaid amount of the claim and if
successful in whole or in part, Indemnitee shall also be entitled to be paid the
expenses of prosecuting such claim. The burden of proving that Indemnitee is not
entitled to an advancement of expenses shall be on the Company.

         12. PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS.

             (a) In making a determination required to be made under Delaware
             law with respect to entitlement to indemnification hereunder, the
             person, persons or entity making such determination shall presume
             that Indemnitee is entitled to indemnification under this Agreement
             if Indemnitee has submitted a request for indemnification in
             accordance with Section 6 of this Agreement, and the Company shall
             have the burden of proof to overcome that presumption in connection
             with the making of any determination contrary to that presumption.
             Neither the failure of the Company or of any person, persons or
             entity to have made a determination prior to the commencement of
             any action pursuant to this Agreement that indemnification is
             proper in the circumstances because Indemnitee has met the
             applicable standard of conduct, nor an actual determination by the
             Company or by any person, persons or entity that Indemnitee has not
             met such applicable standard of conduct, shall be a defense to the
             action or create a presumption that Indemnitee has not met the
             applicable standard of conduct.

             (b) The termination of any Proceeding or of any claim, issue or
             matter therein, by judgment, order, settlement or conviction, or
             upon a plea of NOLO CONTENDERE or its equivalent, shall not (except
             as otherwise expressly provided in this Agreement) of itself
             adversely affect the right of Indemnitee to indemnification or
             create a presumption that Indemnitee did not act in good faith and
             in a manner which he reasonably believed to be in or not opposed to
             the best interests of the

<Page>

             Company or, with respect to any criminal Proceeding, that
             Indemnitee had reasonable cause to believe that his conduct was
             unlawful.

             (c) For purposes of any determination of good faith, Indemnitee
             shall be deemed to have acted in good faith if Indemnitee's action
             is based on the records or books of account of the Enterprise,
             including financial statements, or on information supplied to
             Indemnitee by the officers of the Enterprise in the course of their
             duties, or on the advice of legal counsel for the Enterprise or the
             Board of Directors or counsel selected by any committee of the
             Board of Directors or on information or records given or reports
             made to the Enterprise by an independent certified public
             accountant or by an appraiser, investment banker or other expert
             selected with reasonable care by the Company or the Board of
             Directors or any committee of the Board of Directors. The
             provisions of this Section 12(c) shall not be deemed to be
             exclusive or to limit in any way the other circumstances in which
             the Indemnitee may be deemed to have met the applicable standard of
             conduct set forth in this Agreement.

             (d) The knowledge and/or actions, or failure to act, of any
             director, officer, agent or employee of the Enterprise shall not be
             imputed to Indemnitee for purposes of determining the right to
             indemnification under this Agreement.

         13. REMEDIES OF INDEMNITEE.

             (a) RIGHT TO PETITION COURT. In the event that Indemnitee makes a
             request for payment of Indemnifiable Amounts under Sections 3, 4
             and 5 above or a request for an advancement of Expenses under
             Sections 10 and 11 above and the Company fails to make such payment
             or advancement in a timely manner pursuant to the terms of this
             Agreement, Indemnitee may petition the Delaware Chancery Court to
             enforce the Company's obligations under this Agreement.

             (b) BURDEN OF PROOF. In any judicial proceeding brought under
             Section 13(a) above, the Company shall have the burden of proving
             that Indemnitee is not entitled to payment of Indemnifiable Amounts
             hereunder.

             (c) EXPENSES. The Company agrees to reimburse Indemnitee in full
             for any Expenses incurred by Indemnitee in connection with
             investigating, preparing for, litigating, defending or settling any
             action brought by Indemnitee under Section 13(a) above, or in
             connection with any claim or counterclaim brought by the Company in
             connection therewith, if Indemnitee is successful in whole or in
             part in connection with any such action.

             (d) FAILURE TO ACT NOT A DEFENSE. The failure of the Company
             (including its Board of Directors or any committee thereof,
             independent legal counsel, or stockholders) to make a determination
             concerning the permissibility of the payment of Indemnifiable
             Amounts or the advancement of indemnifiable Expenses under this
             Agreement shall not be a defense in any action brought under

<Page>

             Section 13(a) above, and shall not create a presumption that such
             payment or advancement is not permissible.

         14. DEFENSE OF THE UNDERLYING PROCEEDING.

             (a) NOTICE BY INDEMNITEE. Indemnitee agrees to notify the Company
             promptly upon being served with any summons, citation, subpoena,
             complaint, indictment, information, or other document relating to
             any Proceeding which may result in the payment of Indemnifiable
             Amounts or the advancement of Expenses hereunder; provided,
             however, that the failure to give any such notice shall not
             disqualify Indemnitee from the right, or otherwise affect in any
             manner any right of Indemnitee, to receive payments of
             Indemnifiable Amounts or advancements of Expenses unless the
             Company's ability to defend in such Proceeding is materially and
             adversely prejudiced thereby.

             (b) DEFENSE BY COMPANY. Subject to the provisions of the last
             sentence of this Section 14(b) and of Section 14(c) below, the
             Company shall have the right to defend Indemnitee in any Proceeding
             which may give rise to the payment of Indemnifiable Amounts
             hereunder; provided, however that the Company shall notify
             Indemnitee of any such decision to defend within thirty (30)
             calendar days of receipt of notice of any such Proceeding under
             Section 14(a) above. The Company shall not, without the prior
             written consent of Indemnitee, consent to the entry of any judgment
             against Indemnitee or enter into any settlement or compromise which
             (i) includes an admission of fault of Indemnitee or (ii) does not
             include, as an unconditional term thereof, the full release of
             Indemnitee from all liability in respect of such Proceeding, which
             release shall be in form and substance reasonably satisfactory to
             Indemnitee. This Section 14(b) shall not apply to a Proceeding
             brought by Indemnitee under Section 13(a) above or pursuant to
             Section 22 below.

             (c) INDEMNITEE'S RIGHT TO COUNSEL. Notwithstanding the provisions
             of Section 14(b) above, if in a Proceeding to which Indemnitee is a
             party by reason of Indemnitee's Corporate Status, (i) Indemnitee
             reasonably concludes that he or she may have separate defenses or
             counterclaims to assert with respect to any issue which may not be
             consistent with the position of other defendants in such
             Proceeding, (ii) a conflict of interest or potential conflict of
             interest exists between Indemnitee and the Company, or (iii) if the
             Company fails to assume the defense of such proceeding in a timely
             manner, Indemnitee shall be entitled to be represented by a
             separate legal counsel of Indemnitee's choice at the expense of the
             Company. In addition, if the Company fails to comply with any of
             its obligations under this Agreement or in the event that the
             Company or any other person takes any action to declare this
             Agreement void or unenforceable, or institutes any action, suit or
             proceeding to deny or to recover from Indemnitee the benefits
             intended to be provided to Indemnitee hereunder, Indemnitee shall
             have the right to retain a counsel of Indemnitee's choice, at the
             expense of the Company, to represent Indemnitee in connection with
             any such matter.

<Page>

         15. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to Indemnitee as follows:

             (a) AUTHORITY. The Company has all necessary power and authority to
             enter into, and be bound by the terms of, this Agreement, and the
             execution, delivery and performance of the undertakings
             contemplated by this Agreement have been duly authorized by the
             Company.

             (b) ENFORCEABILITY. This Agreement, when executed and delivered by
             the Company in accordance with the provisions hereof, shall be a
             legal, valid and binding obligation of the Company, enforceable
             against the Company in accordance with its terms, except as such
             enforceability may be limited by applicable bankruptcy, insolvency,
             moratorium, reorganization or similar laws affecting the
             enforcement of creditors' rights generally.

         16. INSURANCE. The Company shall, from time to time, make the good
faith determination whether or not it is practicable for the Company to obtain
and maintain a policy or policies of insurance with a reputable insurance
company providing the Indemnitee with coverage for losses from wrongful acts.
For so long as Indemnitee shall remain a director or executive officer of the
Company and with respect to any such prior service, in all policies of director
and officer liability insurance, Indemnitee shall be named as an insured in such
a manner as to provide Indemnitee the same rights and benefits as are accorded
to the most favorably insured of the Company's officers and directors.
Notwithstanding the foregoing, the Company shall have no obligation to obtain or
maintain such insurance if the Company determines in good faith that such
insurance is not reasonably available, if the premium costs for such insurance
are disproportionate to the amount of coverage provided, or if the coverage

     in its sole discretion, subject to the provisions of Article 3 as to the
     total number of shares available for grants under the Plan.

          (c) STOCK INCENTIVE AGREEMENTS. Each Stock Incentive shall be
     evidenced by a Stock Incentive Agreement executed by the Company and the
     Participant, which shall be in such form and contain such terms and
     conditions as the Board in its discretion may, subject to the provisions of
     the Plan, from time to time determine.

          (d) DATE OF GRANT. The date a Stock Incentive is granted shall be the
     date on which the Board (1) has approved the terms and conditions of the
     Stock Incentive Agreement, (2) has determined the recipient of the Stock
     Incentive and the number of Shares covered by the Stock Incentive and (3)
     has taken all such other action necessary to complete the grant of the
     Stock Incentive.

     7.2. TERMS AND CONDITIONS OF OPTIONS.

          (a) NECESSITY OF STOCK INCENTIVE AGREEMENTS. Each grant of an Option
     shall be evidenced by a Stock Incentive Agreement which shall specify
     whether the Option is an ISO or Non-ISO, and incorporate such other terms
     and conditions as the Board, acting in its absolute discretion, deems
     consistent with the terms of this Plan, including (without limitation) a
     restriction on the number of Shares subject to the Option which first
     become exercisable or subject to surrender during any calendar year. The
     Board and/or the Company shall have complete discretion to modify the terms
     and provisions of an Option in accordance with Article 12 of this Plan even
     though such modification may change the Option from an ISO to Non-ISO.

          (b) DETERMINING OPTIONEES. In determining Employee(s) or Key Person(s)
     to whom an Option shall be granted and the number of Shares to be covered
     by such Option, the Board may take into account the recommendations of the
     Chief Executive Officer of the Company and its other officers, the duties
     of the Employee or Key Person, the present and potential contributions of
     the Employee or Key Person to the success of the Company, the anticipated
     number of years of service remaining before the attainment by the Employee
     of retirement age, and other factors deemed relevant by the Board, in its
     sole discretion, in connection with accomplishing the purpose of this Plan.
     An Employee or Key Person who has been granted an Option to purchase
     Shares, whether under this Plan or otherwise, may be granted one or more
     additional Options. If the Board grants an ISO and a Non-ISO to an Employee
     on the same date, the right of the Employee to exercise or surrender one
     such Option shall not be conditioned on his or her failure to exercise or
     surrender the other such Option.

          (c) EXERCISE PRICE. Subject to adjustment in accordance with Article
     10 and the other provisions of this Article, the Exercise Price shall be as
     set forth in the applicable Stock Incentive Agreement. With respect to each
     grant of an ISO to a Participant who is

                                       8
<Page>

     not a Ten Percent Shareholder, the Exercise Price shall not be less than
     the Fair Market Value on the date the ISO is granted. With respect to each
     grant of an ISO to a Participant who is a Ten Percent Shareholder, the
     Exercise Price shall not be less than one hundred ten percent (110%) of the
     Fair Market Value on the date the ISO is granted. If a Stock Incentive is a
     Non-ISO, the Exercise Price for each Share shall be no less than the
     minimum price required by applicable state law, or by the Company's
     governing instrument, whichever price is greater. Any Stock Incentive
     intended to meet the Performance-Based Exception must be granted with an
     Exercise Price equivalent to or greater than the Fair Market Value of the
     Shares subject thereto. Any Stock Incentive intended to meet the FLSA
     Exclusion must be granted with an Exercise Price equivalent to or greater
     than eighty-five percent (85%) of the Fair Market Value of the Shares
     subject thereto on the date granted.

          (d) OPTION TERM. Each Option granted under this Plan shall be
     exercisable in whole or in part at such time or times as set forth in the
     related Stock Incentive Agreement, but no Stock Incentive Agreement shall:

               (i) make an Option exercisable before the date such Option is
          granted; or

               (ii) make an Option exercisable after the earlier of:

                    A) the date such Option is exercised in full, or

                    B) the date which is the tenth (10th) anniversary of the
               date such Option is granted, if such Option is a Non-ISO or an
               ISO granted to a non-Ten Percent Shareholder, or the date which
               is the fifth (5th) anniversary of the date such Option is
               granted, if such Option is an ISO granted to a Ten Percent
               Shareholder. A Stock Incentive Agreement may provide for the
               exercise of an Option after the employment of an Employee has
               terminated for any reason whatsoever, including death or
               disability. The Employee's rights, if any, upon termination of
               employment will be set forth in the applicable Stock Incentive
               Agreement.

          (e) PAYMENT. Options shall be exercised by the delivery of a written
     notice of exercise to the Company, setting forth the number of Shares with
     respect to which the Option is to be exercised accompanied by full payment
     for the Shares. Payment for shares of Stock purchased pursuant to exercise
     of an Option shall be made in cash or, unless the Stock Incentive Agreement
     provides otherwise, by delivery to the Company of a number of Shares which
     have been owned and completely paid for by the holder for at least six (6)
     months prior to the date of exercise (i.e., "mature shares" for accounting
     purposes) having an aggregate Fair Market Value equal to the amount to be
     tendered, or a combination thereof. In addition, unless the Stock Incentive
     Agreement provides otherwise, the Option may be exercised through a
     brokerage transaction following registration of the Company's equity
     securities under Section 12 of the Securities Exchange Act of 1934 as
     permitted under the provisions of Regulation T applicable to

                                       9
<Page>

     cashless exercises promulgated by the Federal Reserve Board. However,
     notwithstanding the foregoing, with respect to any Option recipient who is
     an Insider, a tender of shares or a cashless exercise must (1) have met the
     requirements of an exemption under Rule 16b-3 promulgated under the
     Exchange Act, or (2) be a subsequent transaction the terms of which were
     provided for in a transaction initially meeting the requirements of an
     exemption under Rule 16b-3 promulgated under the Exchange Act. Unless the
     Stock Incentive Agreement provides otherwise, the foregoing exercise
     payment methods shall be subsequent transactions approved by the original
     grant of an Option. Except as provided in subparagraph (f) below, payment
     shall be made at the time that the Option or any part thereof is exercised,
     and no Shares shall be issued or delivered upon exercise of an Option until
     full payment has been made by the Participant. The holder of an Option, as
     such, shall have none of the rights of a stockholder. Notwithstanding the
     above, and in the sole discretion of the Board, an Option may be exercised
     as to a portion or all (as determined by the Board) of the number of Shares
     specified in the Stock Incentive Agreement by delivery to the Company of a
     promissory note, such promissory note to be executed by the Participant and
     which shall include, with such other terms and conditions as the Board
     shall determine, provisions in a form approved by the Board under which:
     (i) the balance of the aggregate purchase price shall be payable in equal
     installments over such period and shall bear interest at such rate (which
     shall not be less than the prime bank loan rate as determined by the Board)
     as the Board shall approve, and (ii) the Participant shall be personally
     liable for payment of the unpaid principal balance and all accrued but
     unpaid interest. Other methods of payment may also be used if approved by
     the Board in its sole and absolute discretion and provided for under the
     Stock Incentive Agreement.

          (f) CONDITIONS TO EXERCISE OF AN OPTION. Each Option granted under the
     Plan shall vest and shall be exercisable at such time or times, or upon the
     occurrence of such event or events, and in such amounts, as the Board shall
     specify in the Stock Incentive Agreement, provided, however, that
     subsequent to the grant of an Option, the Board, at any time before
     complete termination of such Option, may accelerate the time or times at
     which such Option may vest or be exercised in whole or in part.
     Notwithstanding the foregoing, an Option intended to meet the FLSA
     Exclusion shall not be exercisable for at least six (6) months following
     the date it is granted, except by reason of death, disability, retirement,
     a change in corporate ownership or other circumstances permitted under
     regulations promulgated under the FLSA Exclusion. The Board may impose such
     restrictions on any Shares acquired pursuant to the exercise of an Option
     as it may deem advisable, including, without limitation, vesting or
     performance-based restrictions, restrictions under applicable federal
     securities laws, under the requirements of any stock exchange or market
     upon which such Shares are then listed and/or traded, and under any blue
     sky or state securities laws applicable to such Shares.

          (g) TRANSFERABILITY OF OPTIONS. An Option shall not be transferable or
     assignable except by will or by the laws of descent and distribution and
     shall be exercisable, during the Participant's lifetime, only by the
     Participant; provided, however, that in the event the Participant is
     incapacitated and unable to exercise his or her Option, such Option may be

                                       10
<Page>

     exercised by such Participant's legal guardian, legal representative, or
     other representative whom the Board deems appropriate based on applicable
     facts and circumstances. The determination of incapacity of a Participant
     and the determination of the appropriate representative of the Participant
     who shall be able to exercise the Option if the Participant is
     incapacitated shall be determined by the Board in its sole and absolute
     discretion. Notwithstanding the foregoing, except as otherwise provided in
     the Stock Incentive Agreement, a Non-ISO may also be transferred as a bona
     fide gift (i) to his spouse or lineal descendant or lineal ascendant, (ii)
     to a trust for the benefit of one or more individuals described in clause
     (i), or (iii) to a partnership of which the only partners are one or more
     individuals described in clause (i), in which case the transferee shall be
     subject to all provisions of the Plan, the Stock Incentive Agreement and
     other agreements between the Company and the Participant in connection with
     the exercise of the Option and purchase of Shares. In the event of such a
     gift, the Participant shall promptly notify the Board of such transfer and
     deliver to the Board such written documentation as the Board may in its
     discretion request, including, without limitation, the written
     acknowledgment of the donee that the donee is subject to the provisions of
     the Plan, the Stock Incentive Agreement and other agreements between the
     Company and the Participant.

          (h) SPECIAL PROVISIONS FOR CERTAIN SUBSTITUTE OPTIONS. Notwithstanding
     anything to the contrary in this Article, any Option in substitution for a
     stock option previously issued by another entity, which substitution occurs
     in connection with a transaction to which Code ss.424(a) is applicable, may
     provide for an exercise price computed in accordance with Code ss.424(a)
     and the regulations thereunder and may contain such other terms and
     conditions as the Board may prescribe to cause such substitute Option to
     contain as nearly as possible the same terms and conditions (including
     the applicable vesting and termination provisions) as those contained in
     the previously issued stock option being replaced thereby.

          (i) ISO TAX TREATMENT REQUIREMENTS. With respect to any Option which
     purports to be an ISO, to the extent that the aggregate Fair Market Value
     (determined as of the date of grant of such Option) of stock with respect
     to which such Option is exercisable for the first time by any individual
     during any calendar year exceeds one hundred thousand dollars
     ($100,000.00), such Option shall not be treated as an ISO in accordance
     with Code ss.422(d). The rule of the preceding sentence is applied in the
     order in which Options are granted. Also, with respect to any Option which
     purports to be an ISO, such Option shall not be treated as an ISO if the
     Participant disposes of shares acquired thereunder within two (2) years
     from the date of the granting of the Option or within one (1) year of the
     exercise of the Option, or if the Participant has not meet the requirements
     of Code ss.422(a)(2).

     7.3. TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS. A Stock
Appreciation Right may be granted in connection with all or any portion of a
previously or contemporaneously granted Option or not in connection with an
Option. A Stock Appreciation Right shall entitle the Participant to receive upon
exercise or payment the excess of the Fair Market Value of a

                                       11
<Page>

specified number of Shares at the time of exercise, over a specified price which
shall be not less than the Exercise Price for that number of Shares in the case
of a Stock Appreciation Right granted in connection with a previously or
contemporaneously granted Option, or in the case of any other Stock Appreciation
Right not less than one hundred percent (100%) of the Fair Market Value of that
number of Shares at the time the Stock Appreciation Right was granted. The
exercise of a Stock Appreciation Right shall result in a pro rata surrender of
the related Option to the extent the Stock Appreciation Right has been
exercised.

          (a) PAYMENT. Upon exercise or payment of a Stock Appreciation Right,
     the Company shall pay to the Participant the appreciation in cash or Shares
     (at the aggregate Fair Market Value on the date of payment or exercise) as
     provided in the Stock Incentive Agreement or, in the absence of such
     provision, as the Board may determine.

          (b) CONDITIONS TO EXERCISE. Each Stock Appreciation Right granted
     under the Plan shall be exercisable at such time or times, or upon the
     occurrence of such event or events, and in such amounts, as the Board shall
     specify in the Stock Incentive Agreement; provided, however, that
     subsequent to the grant of a Stock Appreciation Right, the Board, at any
     time before complete termination of such Stock Appreciation Right, may
     accelerate the time or times at which such Stock Appreciation Right may be
     exercised in whole or in part.

          (c) TRANSFERABILITY OF STOCK APPRECIATION RIGHTS. Except as otherwise
     provided in a Participant's Stock Incentive Agreement, no Stock
     Appreciation Right granted under the Plan may be sold, transferred,
     pledged, assigned or otherwise alienated or hypothecated, other than by
     will or by the laws of descent and distribution. Further, except as
     otherwise provided in a Participant's Stock Incentive Agreement, all Stock
     Appreciation Rights granted to a Participant under the Plan shall be
     exercisable, during the Participant's lifetime, only by the Participant;
     provided, however, that in the event the Participant is incapacitated and
     unable to exercise his or her Stock Appreciation Right, such Stock
     Appreciation Right may be exercised by such Participant's legal guardian,
     legal representative, or other representative whom the Board deems
     appropriate based on applicable facts and circumstances. The determination
     of incapacity of a Participant and the determination of the appropriate
     representative of the Participant shall be determined by the Board in its
     sole and absolute discretion. Notwithstanding the foregoing, except as
     otherwise provided in the Stock Incentive Agreement, (A) a Stock
     Appreciation Right which is granted in connection with the grant of a
     Non-ISO may be transferred, but only with the Non-ISO, and (B) a Stock
     Appreciation Right which is not granted in connection with the grant of a
     Non-ISO, may be transferred as a bona fide gift (i) to his spouse or lineal
     descendant or lineal ascendant, (ii) to a trust for the benefit of one or
     more individuals described in clause (i) or (iii) to a partnership of which
     the only partners are one or more individuals described in clause (i), in
     which case the transferee shall be subject to all provisions of the Plan,
     the Stock Incentive Agreement and other agreements between the Company and
     the Participant in connection with the exercise of the Stock Appreciation
     Right. In the event of such a gift, the Optionee shall promptly notify the
     Board of such transfer and deliver to the Board such written documentation
     as the Board

                                       12
<Page>

     may in its discretion request, including, without limitation, the written
     acknowledgment of the donee that the donee is subject to the provisions of
     the Plan, the Stock Incentive Agreement and other agreements between the
     Company and the Participant in connection with the exercise of the Stock
     Appreciation Right.

          (d) SPECIAL PROVISIONS FOR TANDEM SAR's. A Stock Appreciation Right
     granted in connection with an Option may only be exercised to the extent
     that the related Option has not been exercised. A Stock Appreciation Right
     granted in connection with an ISO (1) will expire no later than the
     expiration of the underlying ISO, (2) may be for no more than the
     difference between the exercise price of the underlying ISO and the Fair
     Market Value of the Shares subject to the underlying ISO at the time the
     Stock Appreciation Right is exercised, (3) may be transferable only when,
     and under the same conditions as, the underlying ISO is transferable, and
     (4) may be exercised only (i) when the underlying ISO could be exercised
     and (ii) when the Fair Market Value of the Shares subject to the ISO
     exceeds the exercise price of the ISO.

     7.4. TERMS AND CONDITIONS OF RESTRICTED STOCK AWARDS. Shares awarded
pursuant to Restricted Stock Awards shall be subject to such restrictions as
determined by the Board for periods determined by the Board. Unless the
applicable Stock Incentive Agreement provides otherwise, holders of Restricted
Stock Awards shall be entitled to vote and receive dividends during the periods
of restriction to the same extent as holders of unrestricted Common Stock. The
Board shall have the power to permit, in its discretion, an acceleration of the
expiration of the applicable restriction period with respect to any part or all
of the Shares awarded to a Participant. The Board may require a cash payment
from the Participant in an amount no greater than the aggregate Fair Market
Value of the Shares awarded determined at the date of grant in exchange for the
grant of a Restricted Stock Award or may grant a Restricted Stock Award without
the requirement of a cash payment. A Restricted Stock Award may be transferred,
except as otherwise provided in the Stock Incentive Agreement, as a bona fide
gift (i) to his spouse or lineal descendant or lineal ascendant, (ii) to a trust
for the benefit of one or more individuals described in clause (i), or (iii) to
a partnership of which the only partners are one or more individuals described
in clause (i), in which case the transferee shall be subject to all provisions
of the Plan, the Stock Incentive Agreement, and other agreements between the
Company and the Participant in connection with the Restricted Stock Award. In
the event of such a gift, the Participant shall promptly notify the Board of
such transfer and deliver to the Board such written documentation as the Board
may in its discretion request, including, without limitation, the written
acknowledgment of the donee that the donee is subject to the provisions of the
Plan, the Stock Incentive Agreement and other agreements between the Company and
the Participant in connection with the Restricted Stock Award.

                                  ARTICLE VIII

                              SECURITIES REGULATION

     Each Stock Incentive Agreement may provide that, upon the receipt of Shares
as a result of the exercise of a Stock Incentive or otherwise, the Participant
shall, if so requested by the

                                       13
<Page>

Company, hold such Shares for investment and not with a view of resale or
distribution to the public and, if so requested by the Company, shall deliver to
the Company a written statement satisfactory to the Company to that effect. Each
Stock Incentive Agreement may also provide that, if so requested by the Company,
the Participant shall make a written representation to the Company that he or
she will not sell or offer to sell any of such Shares unless a registration
statement shall be in effect with respect to such Shares under the Securities
Act of 1933, as amended ("1933 Act"), and any applicable state securities law
or, unless he or she shall have furnished to the Company an opinion, in form and
substance satisfactory to the Company, of legal counsel acceptable to the
Company, that such registration is not required. Certificates representing the
Shares transferred upon the exercise or surrender of a Stock Incentive granted
under this Plan may at the discretion of the Company bear a legend to the effect
that such Shares have not been registered under the 1933 Act or any applicable
state securities law and that such Shares may not be sold or offered for sale in
the absence of an effective registration statement as to such Shares under the
1933 Act and any applicable state securities law or an opinion, in form and
substance satisfactory to the Company, of legal counsel acceptable to the
Company, that such registration is not required.

                                   ARTICLE IX

                                  LIFE OF PLAN

     No Stock Incentive shall be granted under this Plan on or after the earlier
of:

          (a) the tenth (10th) anniversary of the effective date of this Plan
     (as determined under Article 4 of this Plan), in which event this Plan
     otherwise thereafter shall continue in effect until all outstanding Stock
     Incentives have been surrendered or exercised in full or no longer are
     exercisable, or

          (b) the date on which all of the Shares reserved under Article 3 of
     this Plan have (as a result of the surrender or exercise of Stock
     Incentives granted under this Plan or lapse of all restrictions under a
     Restricted Stock Award) been issued or no longer are available for use
     under this Plan, in which event this Plan also shall terminate on such
     date.

                                   ARTICLE X

                                   ADJUSTMENT

     Notwithstanding anything in Article 12 to the contrary, the number of
Shares reserved under Article 3 of this Plan, the limit on the number of Shares
which may be granted during a calendar year to any individual under Article 3 of
this Plan, the number of Shares subject to Stock Incentives granted under this
Plan, and the Exercise Price of any Options and the specified exercise price of
any Stock Appreciation Rights, shall be adjusted by the Board in an equitable
manner to reflect any change in the capitalization of the Company, including,
but not limited to, such changes as stock dividends or stock splits.
Furthermore, the Board shall have the right to

                                       14
<Page>

adjust (in a manner which satisfies the requirements of Code ss.424(a)) the
number of Shares reserved under Article 3, and the number of Shares subject
to Stock Incentives granted under this Plan, and the Exercise Price of any
Options and the specified exercise price of any Stock Appreciation Rights in
the event of any corporate transaction described in Code ss.424(a) which
provides for the substitution or assumption of such Stock Incentives. If any
adjustment under this Article creates a fractional Share or a right to
acquire a fractional Share, such fractional Share shall be disregarded, and
the number of Shares reserved under this Plan and the number subject to any
Stock Incentives granted under this Plan shall be the next lower number of
Shares, rounding all fractions downward. An adjustment made under this
Article by the Board shall be conclusive and binding on all affected persons
and, further, shall not constitute an increase in the number of Shares
reserved under Article 3.

                                   ARTICLE XI

                        CHANGE OF CONTROL OF THE COMPANY

     If a Change of Control occurs, and the agreements effectuating the Change
of Control do not provide for the assumption or substitution of the Stock
Incentives granted under this Plan, then, except to the extent otherwise
provided in the Stock Incentive Agreement pertaining to a particular Stock
Incentive, each Stock Incentive shall be governed by applicable law and the
documents effectuating the Change of Control.

                                   ARTICLE XII

                            AMENDMENT OR TERMINATION

     This Plan may be amended by the Board from time to time to the extent that
the Board deems necessary or appropriate; provided, however, no such amendment
shall be made absent the approval of the shareholders of the Company (a) to
increase the number of Shares reserved under Article 3, except as set forth in
Article 10, (b) to extend the maximum life of the Plan under Article 9 or the
maximum exercise period under Article 7, (c) to decrease the minimum Exercise
Price under Article 7, or (d) to change the designation of Employees or Key
Persons eligible for Stock Incentives under Article 6. The Board also may
suspend the granting of Stock Incentives under this Plan at any time and may
terminate this Plan at any time. The Company shall have the right to modify,
amend or cancel any Stock Incentive after it has been granted if (I) the
Participant consents in writing to such modification, amendment or cancellation,
or (II) there is a dissolution or liquidation of the Company or a transaction
described in Article 10 or Article 11, or (III) the Company would otherwise have
the right to make such modification, amendment or cancellation by applicable
law.

                                  ARTICLE XIII

                                  MISCELLANEOUS

     13.1. SHAREHOLDER RIGHTS. No Participant shall have any rights as a
shareholder of the

                                       15
<Page>

Company as a result of the grant of a Stock Incentive to him or to her under
this Plan or his or her exercise of such Stock Incentive pending the actual
delivery of Shares subject to such Stock Incentive to such Participant.

     13.2. NO GUARANTEE OF CONTINUED RELATIONSHIP. The grant of a Stock
Incentive to a Participant under this Plan shall not constitute a contract of
employment and shall not confer on a Participant any rights upon his or her
termination of employment or relationship with the Company in addition to those
rights, if any, expressly set forth in the Stock Incentive Agreement which
evidences his or her Stock Incentive.

     13.3. WITHHOLDING. The Company shall have the power and the right to deduct
or withhold, or require a Participant to remit to the Company as a condition
precedent for the fulfillment of any Stock Incentive, an amount sufficient to
satisfy Federal, state and local taxes, domestic or foreign, required by law or
regulation to be withheld with respect to any taxable event arising as a result
of this Plan and/or any action taken by a Participant with respect to a Stock
Incentive Award. Whenever Shares are to be issued or cash paid to a Participant
upon exercise of an Option, the Company shall have the right to require the
Participant to remit to the Company, as a condition of exercise of the Option,
an amount sufficient to satisfy federal, state and local withholding tax
requirements at the time of exercise. However, notwithstanding the foregoing, to
the extent that a Participant is an Insider, satisfaction of withholding
requirements by having the Company withhold Shares may only be made to the
extent that such withholding of Shares (1) has met the requirements of an
exemption under Rule 16b-3 promulgated under the Exchange Act, or (2) is a
subsequent transaction the terms of which were provided for in a transaction
initially meeting the requirements of an exemption under Rule 16b-3 promulgated
under the Exchange Act. Unless the Stock Incentive Agreement provides otherwise,
the withholding of shares to satisfy federal, state and local withholding tax
requirements shall be a subsequent transaction approved by the original grant of
a Stock Incentive. Notwithstanding the foregoing, in no event shall payment of
withholding taxes be made by a retention of Shares by the Company unless the
Company retains only Shares with a Fair Market Value equal to the minimum amount
of taxes required to be withheld.

     13.4. NOTIFICATION OF DISQUALIFYING DISPOSITIONS OF ISO OPTIONS. If a
Participant sells or otherwise disposes of any of the Shares acquired pursuant
to an Option which is an ISO on or before the later of (1) the date two (2)
years after the date of grant of such Option, or (2) the date one (1) year after
the exercise of such Option, then the Participant shall immediately notify the
Company in writing of such sale or disposition and shall cooperate with the
Company in providing sufficient information to the Company for the Company to
properly report such sale or disposition to the Internal Revenue Service. The
Participant acknowledges and agrees that he may be subject to income tax
withholding by the Company on the compensation income recognized by Participant
from any such early disposition by either (or both) his payment to the Company
in cash or his payment out of the current wages or earnings otherwise payable to
him by the Company, as the Company shall require, and agrees that he shall
include the compensation from such early disposition in his gross income for
federal tax purposes. Participant also acknowledges that the Company may
condition the exercise of any Option which is an ISO on the Participant's
express written agreement with these provisions of this Plan.

     13.5. TRANSFER. The transfer of an Employee between or among the Company, a
Subsidiary or a Parent shall not be treated as a termination of his or her
employment under this Plan.

     13.6. CONSTRUCTION. This Plan shall be construed under the laws of the
State of Delaware.

     13.7. ADDENDUM A: CALIFORNIA GRANTEES. Addendum A attached hereto shall be
incorporated by reference in its entirety and shall only be applicable to the
grant of Stock Incentives under the Plan to grantees who are located in or
providing services to the Company or one of its Subsidiaries in the State of
California.

     13.8. ADDENDUM B: UK GRANTEES. Addendum B attached hereto shall be
incorporated by reference in its entirety and shall only be applicable to the
grant of Stock Incentives under the Plan to grantees who are located in or
providing services to the Company or one of its Subsidiaries in the United
Kingdom.

                                ADDENDUM A TO THE
                               OPTIUM CORPORATION
                              STOCK INCENTIVE PLAN

     Notwithstanding anything stated to the contrary in the Plan, this Addendum
A to the Plan shall apply for purposes of all Stock Incentives granted under the
Plan to employees, directors and consultants located in or providing services to
the Company or any Subsidiary in California until such time as the Shares become
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act. All capitalized terms, to the extent not defined herein, shall have the
meanings set forth in the Plan.

     1. EXERCISE PRICE. The exercise price per share for the Shares covered by a
Option shall be determined by the Committee at the time of grant; PROVIDED THAT,
if the Option is: (i) a Non-ISO and the grantee is not a Ten Percent
Shareholder, the exercise price may be no less than eighty-five percent (85%) of
the Fair Market Value of a Share on the date the Option is granted; (ii) an ISO
and the grantee is not a Ten Percent Shareholder, the exercise price may be no
less than one hundred percent (100%) of the Fair Market Value of a Share on the
date the Option is granted, or (iii) granted to a Ten Percent Shareholder
(whether an ISO or a Non-ISO), the exercise price may be no less than one
hundred ten percent (110%) of the Fair Market Value of a Share on the date the
Option is granted. Notwithstanding the foregoing, an Option (whether an ISO or a
Non-ISO) may be granted with an exercise price lower than the minimum exercise
price set forth above if such Option is granted pursuant to an assumption or
substitution for another stock option in a manner qualifying under the
provisions of Section 424(a) of the Code.

     2. PURCHASE PRICE. The purchase price for any Shares purchased pursuant to
a Restricted Stock Award shall be at least eighty-five percent (85%) of the Fair
Market Value of the Shares at the time the grantee is granted such Restricted
Stock Award or at the time the purchase is consummated. Notwithstanding the
foregoing, if the Restricted Stock Award is granted to a Ten Percent
Shareholder, the purchase price shall be one hundred percent (100%) of the Fair
Market Value of the Shares at the time the grantee is granted such Award or at
the time the purchase is consummated.

     3. EXERCISABILITY AND OPTION TERM. Options shall become exercisable at such
time or times, whether or not in installments, as shall be determined by the
Committee and set forth in the Stock Incentive Agreement evidencing such Option;
PROVIDED THAT, with the exception of Options granted to officers, directors, or
consultants of the Company or any Subsidiary, no Option shall become exercisable
at a rate less than twenty percent (20%) per year over a period of five (5)
years from the date of grant of such Option, subject to the grantee's continued
service relationship with the Company or any Subsidiary. Notwithstanding the
foregoing, no Option shall be exercisable on or after the tenth (10th)
anniversary of the date of grant of such Option or, in the case of a Ten Percent
Sharehold who is granted an ISO, such ISO shall not be exercisable on or after
the fifth (5th) anniversary of the date of grant of such Option.

     4. TERMINATION OF SERVICE RELATIONSHIP. In the event that a grantee's
service relationship terminates, such grantee may thereafter exercise their
Option, to the extent that it was vested and exercisable on the date of such
termination, until the date specified below. Any

<Page>

portion of the Option that is not exercisable on the date of termination of such
service relationship shall immediately expire and be null and void.

     Once any portion of the Option becomes vested and exercisable, the
grantee's right to exercise such Option (or the grantee's representatives and
legatees as applicable) in the event of a termination of the grantee's service
relationship shall continue until the earliest of: (i) the date which is: (A)
six (6) months following the date on which the grantee's service relationship
terminates due to death or Disability (or such longer period of time as
determined by the Committee and set forth in the applicable Stock Incentive
Agreement), or (B) thirty (30) days following the date on which the grantee's
service relationship terminates if the termination is due to any other reason
(or such longer period of time as determined by the Committee and set forth in
the applicable Stock Incentive Agreement), or (ii) the Expiration Date set forth
in the Notice of Grant of Stock Option; PROVIDED THAT, notwithstanding the
foregoing, a Stock Incentive Agreement may provide that if the grantee's service
relationship is terminated for "cause" (as defined in the applicable Stock
Incentive Agreement), the Option shall terminate immediately and be null and
void upon the date of the grantee's termination and shall not thereafter be
exercisable.

     "DISABILITY" shall mean the inability of the grantee, in the opinion of a
qualified physician acceptable to the Company, to perform the major duties of
the grantee's position with the Company or any Subsidiary because of the
sickness or injury of the grantee.

     5. NONTRANSFERABILITY OF OPTION. No Option shall be transferable by the
grantee otherwise than by will or the laws of descent and distribution; PROVIDED
THAT, a Non-ISO may provide in the applicable Stock Incentive Agreement that it
is transferable in any manner permitted by Rule 701 of the Act.

     6. PROVISION OF INFORMATION. At least annually, each grantee shall receive
financial statements of the Company; PROVIDED THAT, the Company shall not be
required to provide such information to key employees whose duties in connection
with the Company assure them access to equivalent information.

     7. REPURCHASE RIGHTS/RIGHT OF FIRST REFUSAL. Shares issued pursuant to
Stock Incentives may be subject to a right of first refusal, one or more
repurchase rights or other conditions and restrictions as determined by the
Committee and set forth in the applicable Stock Incentive Agreement. The Company
shall have the right to assign to any person at any time any repurchase right it
may have, whether or not such right is then exercisable.

     a. REPURCHASE RIGHT. Any repurchase right shall be at such purchase price
as is set forth in the Stock Incentive Agreement PROVIDED THAT: (i) if the
purchase price is equal to or greater than the Fair Market Value of the shares
to be repurchased (measured as of the date of termination of employment), then
such repurchase right must be exercised for cash or cancellation of purchase
money indebtedness for such shares within ninety (90) days of the termination of
employment (or, if later, within ninety (90) days of the exercise of the
applicable Option) and such repurchase right must terminate upon an initial
public offering; and (ii) if the purchase price is equal to the original
purchase price, such repurchase right must lapse at a rate of at least twenty
percent (20%) per year from the date of grant of the Stock Incentive and such
repurchase right must be exercised for cash or cancellation of purchase money
indebtedness for

                                       2

<Page>

the shares within ninety (90) days of the termination of employment (or, if
later, within ninety (90) days of the exercise of the applicable Option).
Notwithstanding the foregoing, Stock Incentives held by officers, directors or
consultants of the Company or any Subsidiary may be subject to additional or
greater restrictions.

     b. RIGHT OF FIRST REFUSAL. Any right of first refusal must: (i) be
triggered by an offer to purchase Shares received pursuant to a Stock Incentive
from a bona fide third-party offeror where the grantee desires to sell the
Shares; (ii) require the Company to make its election to purchase the Shares
subject to such right of first refusal, if at all, by giving notice of such
election no more than thirty (30) days after receipt of notice of such offer
from the grantee; and (iii) require the Company to purchase all, but not less
than all, of the Shares subject to such bona fide offer upon exercise of the
right of first refusal (unless the grantee consents to sell fewer Shares) on the
same terms offered by the bona fide third-party offeror within sixty (60) days
after receipt of the notice described above (unless a longer period is offered
by the bona fide third party offeror).

          established for the benefit of full-time directors and employees, who
          are UK Individuals, of the Company [UK SUBSID] and any other companies
          of which the Company has control (as defined in Section 187(2) of the
          Act).

     2.2  This Sub-Plan has been established in order to ensure that Options
          granted under Article 7.1 of the Plan to UK Individuals are granted
          under a share option plan approved under Schedule 9.

     2.3  The rules of this Sub-Plan should be read in conjunction with the Plan
          and are subject to the terms and conditions of the Plan except to the
          extent that the terms and conditions of the Plan differ from or
          conflict with the terms set out in this Sub-Plan.

     2.4  This Sub-Plan applies to any grant of Options made under the Plan to
          UK Individuals if, at the date of grant, such Options are specified as
          having been granted subject to the terms and conditions of this
          Sub-Plan.

3.   ELIGIBILITY

     3.1  A UK Individual shall not be entitled to be granted Options under this
          Sub-Plan unless he is an Eligible Employee on the date on which an
          Option is granted. Article 7.1(a) of the Plan shall be construed
          accordingly.

                                       2

4.   SHARES SUBJECT TO THIS SUB-PLAN

     4.1  The Shares over which Options may be granted under this Sub-Plan must
          form part of the ordinary share capital (as defined in section 832(1)
          of the Act) of the Company. The Shares must at all times comply with
          the terms of the Plan and the requirements of Paragraphs 10 to 14 of
          Schedule 9.

5.   INDIVIDUAL LIMIT

     5.1  No Option shall be granted to an Eligible Employee under this Sub-Plan
          at any time if it would result in the aggregate Market Value of the
          Shares which he may acquire in pursuance of rights obtained under this
          Sub-Plan and the aggregate market value of shares which the Eligible
          Employee could acquire by the exercise of an option under any other
          share option plan approved under Schedule 9 (not being a
          savings-related plan) and established by the Company or by any
          associated company (as defined in Section 416 of the Act) of the
          Company and not exercised, to exceed or further exceed (pound)30,000
          or such other limit contained from time to time in Paragraph 28(1) of
          Schedule 9.

     5.2  For the purpose of Rule 5.1:

          (a)  in respect of Options previously granted under this Sub-Plan, if
               any, the Market Value of the Shares shall be the Market Value
               originally determined under Rule 6 at the time that the Option
               was granted; and

          (b)  in the case of rights obtained under any other share option plan
               approved under Schedule 9 (not being a savings-related plan), the
               market value of shares shall be calculated as at the time when
               the option to acquire those shares was obtained, or such earlier
               time as may have been agreed with the Inland Revenue.

     5.3  If the market value of the Shares is expressed in a currency other
          than pounds sterling, it shall be converted into pounds sterling at
          the closing mid-market exchange rate for that currency on the date of
          grant of the relevant option, as published by the Financial Times.

     5.4  If the Board attempts to grant an Option under this Sub-Plan which is
          inconsistent with Rule 5.1, the Option granted under this Sub-Plan
          will be limited and take effect on a basis consistent with the
          provisions of Rule 5.1.

6.   EXERCISE PRICE OF OPTIONS

     6.1  The Exercise Price at which any Option granted under this Sub-Plan may
          be exercised shall be the Approved Exercise Price.

                                       3
<Page>

     6.2  The Approved Exercise Price shall mean the price per Share, as
          determined by the Board, at which an Eligible Employee may acquire
          Shares upon the exercise of an Option granted to him under this
          Sub-Plan. The Approved Exercise Price shall not be less than the
          Market Value of a Share on the date of grant. Article 7.2(c) of the
          Plan shall be construed accordingly.

7.   CAPITAL ADJUSTMENT

     7.1  The price at which Shares may be acquired on the exercise of any
          Option and the number of Shares thereunder may be adjusted as
          described in Article 10 of the Plan (Adjustment) only in the event of
          a variation in the share capital of the Company within the meaning of
          Paragraph 29 of Schedule 9 and only if the prior approval of the
          Inland Revenue has been obtained for such adjustment.

8.   EXERCISE OF OPTION

     8.1  Each Option shall be exercisable at such time or times as specified in
          the applicable Stock Option Agreement. Article 7.2 (f) will not apply
          to Options granted under this Sub-Plan.

     8.2  A Optionholder will not be able to exercise his Option granted under
          this Sub-Plan if at the proposed time of exercise he is ineligible to
          participate in the Sub-Plan by virtue of Paragraph 8 of Schedule 9
          (material interests in close companies).

     8.3  The Company shall not later than 30 days after the receipt of the
          notice of exercise of an Option (given in accordance with the
          provisions of the Plan) together with the payment of the aggregate
          Exercise Price in respect of the Shares to be issued or transferred
          pursuant to the exercise of an Option, allot and issue credited as
          fully paid to the Optionholder and cause to be registered in his name
          the number of Shares validly specified in the written notice or
          procure the transfer of such Shares.

     8.4  Notwithstanding any provision in the Plan to the contrary, the Board
          may not at any time buy out for a payment in cash or shares an Option
          granted under this Sub-Plan.

     8.5  The consideration to be paid for the Shares to be issued upon exercise
          of an Option shall comprise entirely of cash or cash equivalent only.
          Article 7.2(e) of the Plan shall be construed accordingly.

     8.6  If an Optionholder dies, his Option shall terminate within a period
          not exceeding a year following his death, but not later than the date
          the Option expires pursuant to its terms. Article 7.2(g) of the Plan
          shall be construed accordingly.

                                       4

<Page>

9.   NON TRANSFERABILITY OF OPTIONS

     9.1  Subject to the rights of exercise by the Optionholder' s personal
          representatives, every Option granted under this Sub-Plan shall be
          personal to the Optionholder and may not be sold, transferred or
          disposed of in any way. Article 7.2(g) of the Plan shall be construed
          accordingly.

10.  CHANGE OF CONTROL

     10.1 For the purposes of this Sub-Plan (and notwithstanding anything
          contained in the Plan, and in particular Article 11 thereof), the
          holder of an Option which has been granted under this Sub-Plan shall
          not be entitled to receive options over shares of a successor
          corporation or another corporation in consideration for the release of
          this option on any consolidation, merger, change of control or
          amalgamation with or into another corporation unless, such corporation
          makes an appropriate offer, and the holder of an option agrees within
          the appropriate period referred to in Rule 10.2 below and:

          10.1.1 the successor corporation obtains control of the Company as a
                 result of making a general offer to acquire the whole of the
                 issued ordinary share capital of the Company (which is made
                 on the condition such that if it is satisfied the successor
                 corporation will have control of the Company);

          10.1.2 the successor corporation obtains control of the Company as a
                 result of making a general offer to acquire all the Shares
                 in the Company which are of the same class as the Shares which
                 may be acquired by the exercise of Options granted under this
                 Sub-Plan (ignoring any Shares which are already owned by it
                 or a member of the same group of companies);

          10.1.3 the successor company obtains control of the Company in
                 pursuance of a compromise or arrangement sanctioned by the
                 Court under Section 425 of the United Kingdom Companies
                 Act 1985 ("the 1985 Act") or the local equivalent of the same,
                 if accepted by the Inland Revenue as closely comparable to
                 the UK legislation; or

          10.1.4 the successor company becomes bound or entitled to acquire
                 Shares in the Company under Sections 428 to 430F of the 1985
                 Act or the local equivalent of the same, if accepted by the
                 Inland Revenue as closely comparable to the UK legislation.

     10.2 Where Rule 10.1 above applies:

          10.2.1 subject to the limitations of the Plan, where any such holder
                 of an Option granted under this Sub-Plan is entitled to
                 receive options over shares of a successor corporation or
                 another corporation, he may at any time within the appropriate
                 period (within the meaning of Paragraph 15(2) of Schedule

                                       5

<Page>

                 9) release any Option which has not lapsed ("the old option")
                 in consideration of the grant to him of an option ("the new
                 option") which (for the purposes of Paragraph 15 of Schedule
                 9) is equivalent to the old option but relates to shares in a
                 different company (whether the successor corporation itself or
                 some other company falling within Paragraph 10(b) or 10(c) of
                 Schedule 9). For this purpose, the new option shall not be
                 regarded as equivalent to the old option unless the conditions
                 set out in Paragraph 15(3) of Schedule 9 are satisfied; and

          10.2.2 for the purposes of any application of the provisions of this
                 Sub-Plan, where any holder of an Option has released an old
                 option, any new option granted shall be regarded as having
                 been granted at the same time as the old option. With
                 effect from the date of release, the new option shall be
                 subject to the same provisions of this Sub-Plan as applied
                 to the old option except that the following terms have the
                 meaning assigned to them in this Rule 10.2.2 and not the
                 meanings elsewhere in the Plan or in this Sub-Plan:

                 "SHARES" means fully paid ordinary shares in the capital of
                 the corporation over whose shares new options have been
                 granted and which satisfy the conditions specified in
                 Paragraphs 10 to 14 of Schedule 9.

                 "BOARD" means the Board of Directors of the corporation in
                 respect of whose shares new options have been granted.

                 "COMMITTEE" means the committee of the Board of Directors of
                 the corporation in respect of whose shares new options have
                 been granted.

                 "COMPANY" means the corporation in respect of whose shares new
                 options have been granted.

     10.3 Notwithstanding anything contained in the Plan, if the Company merges
          or is consolidated with another corporation under circumstances where
          the Company is not the surviving corporation, no Options may be
          granted under this Sub-Plan following such merger or consolidation
          apart from new options granted by the successor corporation pursuant
          to this Rule 10.

     10.4 In this Rule 10, control has the meaning given to it by Section 840 of
          the Act.

11.  AMENDMENT OF THIS SUB-PLAN

     11.1 The terms of this Sub-Plan shall not be amended nor shall the Plan be
          amended if it shall effect this Sub-Plan, except to the extent that
          the Inland Revenue has approved such amendments. No such amendment
          shall take effect before the date on which it is approved by the
          Inland Revenue. Article 12 of the Plan shall be construed accordingly.

                                       6

12.  TERMS OF EMPLOYMENT

     12.1 Neither these Rules nor the Plan form any part of any Eligible
          Employee's terms of employment and nothing in the Plan or the Sub-Plan
          may be construed as imposing on the Company, [UK SUBSID] or any other
          related entity a contractual obligation to offer participation in the
          Plan or the Sub-Plan to any Eligible Employee. If any Optionholder
          ceases to be an Eligible Employee for any reason, he shall not be
          entitled by way of compensation for loss of office or otherwise
          howsoever to any sum or other benefit to compensate him for the loss
          of any rights under the Sub-Plan.

13.  DATA PROTECTION

     13.1 By participating in the Sub-Plan, the Optionholder consents to the
          holding and processing of personal data provided by the Optionholder
          to the Company or his employing company for all purposes relating to
          the operation of the Sub-Plan. These include, but are not limited to:

          -    administering and maintaining Optionholder records;

          -    providing information to trustees of any employee benefits trust,
               registrars, brokers or third party administrators of the
               Sub-Plan;

          -    providing information to future purchasers of the Company or the
               business in which the Optionholder works; and

          -    transferring information about the Optionholder to a country or
               territory outside the European Economic Area.

14.  STOCK OPTION AGREEMENTS

     14.1 When the Board, under the powers conferred by the Plan, determines the
          terms and conditions of any Option granted under this Sub-Plan, such
          terms and conditions shall:

          (a)  be objective, specified at the date the Option is granted and set
               out in the Stock Option Agreement issued under Section 7.2(a) of
               the Plan; and

          (b)  be such that rights to exercise such Options after the
               fulfillment or attainment of any terms and conditions so
               specified shall not be dependent upon the further discretion of
               any person; and

          (c)  not be capable of amendment, variation or waiver unless an event
               occurs which causes the Board to reasonably consider that a
               waived, varied or amended term and condition would be a fairer

                                       7

<Page>

               measure of performance and would be no more difficult to satisfy.

     14.2 The Board shall obtain the prior approval of the Inland Revenue for
          the form of Stock Option Agreement issued under Section 7.2(a) of the
          Plan in relation to Options granted under this Sub-Plan.

                             STOCK OPTION AGREEMENT

                          UNDER THE OPTIUM CORPORATION
                        STOCK INCENTIVE PLAN, AS AMENDED

     Pursuant to the Optium Corporation Stock Incentive Plan (the "PLAN"),
Optium Corporation, a Delaware corporation (together with its successors
thereto, the "COMPANY"), hereby grants to the person (the "GRANTEE"), named in
the Notice of Grant of Stock Option attached hereto (the "NOTICE") to which this
Stock Option Agreement (the "OPTION AGREEMENT") is attached, an option (together
with the Notice, referred to herein as the "OPTION") to purchase on or prior to
the expiration date specified in the Notice (the "EXPIRATION DATE"), or such
earlier date as is specified herein, all or any part of the number of shares of
Stock of the Company indicated in the Notice (the "OPTION SHARES," and such
shares once issued shall be referred to as the "ISSUED SHARES," each as adjusted
pursuant to SECTION 5 hereof), at the exercise price per share specified in the
Notice (the "EXERCISE PRICE"), subject to the terms and conditions set forth in
this Option Agreement, the Notice and the Plan. All capitalized terms used
herein and not otherwise defined shall have the respective meanings set forth in
the Notice and the Plan (as applicable).

     If this Option is designated as an Incentive Stock Option in the Notice,
this Option is intended to qualify as an "incentive stock option" as defined in
Section 422(b) of the Code. To the extent that any portion of this Option does
not so qualify as an Incentive Stock Option or, if this Option is designated as
a Non-Qualified Stock Option in the Notice, it shall be deemed a Non-Qualified
Stock Option. The Grantee should consult with the Grantee's own tax advisor
regarding the tax effects of this Option (and any requirements necessary to
obtain favorable income tax treatment under Section 422 or the Code, including,
but not limited to, holding period requirements).

     1.  VESTING AND EXERCISABILITY.
         --------------------------

         (a) No portion of this Option may be exercised until such portion shall
have vested.

         (b) Except as set forth below and in SECTION 6 hereof, this Option
shall be exercisable on and after the initial Vesting Date and prior to the
termination of the Option as provided herein, in an amount not to exceed the
number of Vested Shares (as determined in the Notice) less the number of shares
previously acquired upon exercise of this Option. In no event shall this Option
be exercisable for more than the Number of Option Shares (as designated in the
Notice).

         (c) In the event that the Grantee's Service Relationship terminates,
this Option may thereafter be exercised, to the extent it was vested and
exercisable on the date of such termination, until the date specified in SECTION
1 (d) hereof. Any portion of this Option that is not exercisable on the date of
termination of the Service Relationship shall immediately expire and be null and
void. "SERVICE RELATIONSHIP" means the grantee's employment or service with the
Company or its Parent or any of its Subsidiaries, whether in the capacity of an
employee, director

<Page>

or a consultant. Unless otherwise determined by the Committee, a grantee's
Service Relationship shall not be deemed to have terminated merely because of a
change in the capacity in which the grantee renders service to the Company or
its Parent or any of its Subsidiaries or a transfer between locations of the
Company or its Parent or any of its Subsidiaries, PROVIDED THAT there is no
interruption or other termination of the Service Relationship. Subject to the
foregoing, the Company, in its discretion, shall determine whether the grantee's
Service Relationship has terminated and the effective date of such termination.

         (d) Subject to the provisions of SECTION 6 hereof, once any portion of
this Option becomes vested and exercisable, it shall continue to be exercisable
by the Grantee or his or her representatives and legatees as contemplated herein
at any time or times prior to the earliest of (i) the date which is (A) twelve
(12) months following the date on which the Grantee's Service Relationship
terminates due to death or disability (B) three (3) months following the date on
which the Grantee's Service Relationship terminates if the termination is due to
any other reason, or (ii) the Expiration Date set forth in the Notice; PROVIDED,
HOWEVER, that notwithstanding the foregoing, if the Grantee's Service
Relationship is terminated for Cause, this Option shall terminate immediately
and be null and void upon the date of the Grantee's termination and shall not
thereafter be exercisable.

         (e) If designated as an Incentive Stock Option in the Notice, the
Grantee understands that in order to obtain the benefits of an incentive stock
option under Section 422 of the Code, subject to any amendments thereof, no sale
or other disposition may be made of Issued Shares for which incentive stock
option treatment is desired within the one (1) year period after the day of the
issuance of such Issued Shares to him or her (i.e., the exercise date), nor
within the two (2) year period after the grant of this Option and further that
this Option must be exercised, if and to the extent permitted hereunder, within
three (3) months after termination of employment (or twelve (12) months in the
case of death or "disability" (as defined in Code Section 22(e)(3))) to qualify
as an incentive stock option. If the Grantee disposes (whether by sale, gift,
transfer or otherwise) of any such Issued Shares within either of these periods,
he or she agrees to notify the Company within thirty (30) days after such
disposition. The Grantee also agrees to provide the Company with any information
concerning any such dispositions required by the Company for tax purposes.
Further, to the extent that the aggregate Fair Market Value (determined as of
the time that the applicable option is granted) of the shares of Stock with
respect to which all Incentive Stock Options held by the Grantee are exercisable
for the first time during any calendar year (under all option plans of the
Company, its Parent and/or its Subsidiaries) exceeds $100,000, such Incentive
Stock Options shall constitute Non-Qualified Stock Options. For purposes of this
SECTION 1(e), Incentive Stock Options shall be taken into account in the order
in which they were granted. If pursuant to the above, an Incentive Stock Option
is treated as an Incentive Stock Option in part and a Non-Qualified Stock Option
in part, the Grantee may designate which portion of the Option the Grantee is
exercising. In the absence of such designation, the Grantee shall be deemed to
have exercised the Incentive Stock Option portion of the Option first.

     2.  EXERCISE OF OPTION.
         ------------------

         (a) The Grantee may exercise this Option only by delivering an Option
exercise notice (an "EXERCISE NOTICE") in substantially the form of APPENDIX A

                                      -2-

<Page>

attached hereto to the Company's Chief Financial Officer or, if none, the Chief
Executive Officer, indicating his or her election to purchase some or all of the
Option Shares with respect to which this Option has vested at the time of
delivery of such Exercise Notice (which amount shall be specified in the
Exercise Notice), accompanied by payment in full of the aggregate Exercise
Price; PROVIDED that such exercise shall be effective only upon receipt by such
officer of the Exercise Notice and the aggregate Exercise Price. Payment of the
aggregate Exercise Price for the Option Shares elected to be purchased by the
Grantee may be made by one or more of the following methods:

              (i) in cash, by certified or bank check, or other instrument
acceptable to the Committee in U.S. funds payable to the order of the Company in
an amount equal to the aggregate Exercise Price of such Option Shares;

              (ii) if permitted by the Committee at the time of exercise, in its
sole and absolute discretion, by the Grantee delivering to the Company a
promissory note (which may be recourse or partial recourse to the Grantee) in a
form approved by Company; PROVIDED THAT at least so much of the exercise price
as represents the par value of the Stock to be issued shall be paid other than
with a promissory note if otherwise required by state law;

              (iii) after the closing of the Company's first fully underwritten,
firm commitment public offering pursuant to an effective registration statement
under the Act, other than on Forms S-4 or S-8 or their then equivalents,
covering the offer and sale by the Company of its equity securities or such
other event as a result of or following which the stock shall be publicly held
(an "INITIAL PUBLIC OFFERING"), if permitted by the Committee, at the discretion
of the Committee at the time of exercise, (x) through the delivery (or
attestation to ownership) of shares of Stock with an aggregate Fair Market Value
(as of the date such shares are delivered or attested to) equal to the aggregate
Exercise Price and that have been purchased by the Grantee on the open market or
that have been held by the Grantee for at least six (6) months and are not
subject to restrictions under any plan of the Company, or (y) by the Grantee
delivering to the Company a properly executed Exercise Notice together with
irrevocable instructions to a broker to promptly deliver to the Company cash or
a check payable and acceptable to the Company to pay the Exercise Price of such
Option Shares; PROVIDED THAT in the event the Grantee chooses such payment
procedure, the Grantee and the broker shall comply with such procedures and
enter into such agreements of indemnity and other agreements as the Committee
shall prescribe as a condition of such payment procedure; or

              (iv) a combination of the payment methods set forth in clauses
(i), (ii) and (iii) above.

         (b) Certificates for the Option Shares so purchased will be issued and
delivered to the Grantee upon compliance to the satisfaction of the Committee
with all requirements under applicable laws or regulations in connection with
such issuance. Until the Grantee shall have complied with the requirements
hereof and of the Plan, including the withholding requirements set forth in
SECTION 7 hereof, the Company shall be under no obligation to issue the Option
Shares subject to this Option, and the determination of the Committee as to such
compliance shall be final and binding on the Grantee. The Grantee shall not be
deemed to be the holder of, or to have any of the rights of a holder with
respect to Issued Shares unless and until this Option shall have been exercised
pursuant to the terms hereof, the Company shall have issued and

                                      -3-

<Page>

delivered such Issued Shares to the Grantee, and the Grantee's name shall have
been entered as a stockholder of record on the books of the Company. Thereupon,
the Grantee shall have full dividend and other ownership rights with respect to
such Issued Shares, subject to the terms of this Option Agreement.

         (c) The Company shall not be required to issue fractional shares upon
the exercise of this Option.

         (d) Notwithstanding any other provision hereof or of the Plan, no
portion of this Option shall be exercisable after the earlier of the Expiration
Date or the termination of this Option as contemplated by SECTION 1(d) and
SECTION 6 hereof.

     3. SUBJECT TO PLAN.
        ---------------

         This Option is subject to all of the terms and conditions set forth in
the Plan. Notwithstanding anything in this Option Agreement or the Notice to the
contrary, to the extent of any conflict between the terms of the Plan, this
Option Agreement, and the Notice, the terms of the Plan shall control.

      4. TRANSFERABILITY.
         ---------------

         This Option is personal to the Grantee and is not transferable by the
Grantee in any manner other than by will or by the laws of descent and
distribution; PROVIDED THAT if this Option is designated as a Non-Qualified
Stock Option, this Option may also be transferred by the Grantee, without
consideration for the transfer, to the Grantee's spouse, parents, siblings,
children (natural or adopted), stepchildren, a trust for their sole benefit of
which the Grantee is the settlor or a limited partnership or other
unincorporated entity in which the partners or beneficiaries are the foregoing
(each a "PERMITTED TRANSFEREE"); PROVIDED THAT the transferee agrees in writing
with the Company to be bound by all of the terms and conditions of the Plan and
this Option Agreement. This Option may be exercised during the Grantee's
lifetime only by the Grantee (or by the Grantee's legal representative or
guardian in the event of the Grantee's incapacity) or by a Permitted Transferee
pursuant to this SECTION 4. The Grantee may elect to designate a beneficiary by
providing written notice of the name of such beneficiary to the Company, and may
revoke or change such designation at any time by filing written notice of
revocation or change with the Company; such beneficiary may exercise the
Grantee's Option in the event of the Grantee's death to the extent provided
herein. If the Grantee does not designate a beneficiary, or if the designated
beneficiary predeceases the Grantee, the executor of the Grantee may exercise
this Option to the extent permitted herein in the event of the Grantee's death.

     5. ADJUSTMENT UPON CHANGES IN CAPITALIZATION.
        -----------------------------------------

         Subject to SECTION 6 hereof, if, as a result of any reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar change in the Company's capital stock, the outstanding
shares of Stock are increased or decreased or are exchanged for a different
number or kind of shares or other securities of the Company, or additional
shares or new or different shares or other securities of the Company or other
non-cash

                                       -4-

<Page>

assets are distributed with respect to such shares of Stock or other
securities, or, if, as a result of any merger, consolidation or sale of all or
substantially all of the assets of the Company, the outstanding shares of Stock
are converted into or exchanged for a different number or kind of shares or
other securities of the Company or any successor entity (or a parent or
subsidiary thereof), the Committee shall make an appropriate or proportionate
adjustment in the number and kind of shares or other securities subject to this
Option and the exercise price for each share subject to this Option, without
changing the aggregate Exercise Price of this Option (i.e., the Exercise Price
multiplied by the number of shares of Stock or other securities subject to this
Option shall be the same both before and after any adjustment pursuant to this
SECTION 5); PROVIDED THAT the adjusted Exercise Price may not be less than the
par value of the Stock. After any such adjustment, all references herein to
Stock or common stock shall be deemed to refer to the security that is subject
to acquisition upon exercise of this Option and all references to the Company
shall be deemed to refer to the issuer of such security. The adjustment by the
Committee shall be final, binding and conclusive. No fractional shares of Stock
shall be issued under the Plan resulting from any such adjustment, but the
Committee in its discretion may either make a cash payment in lieu of fractional
shares or round any resulting fractional share down to the nearest whole number.

     6. EFFECT OF CERTAIN TRANSACTIONS.
        -------------------------------

         Upon the effectiveness of a Change of Control, unless provision is made
in connection with the Change of Control for the assumption of all outstanding
Awards, or the substitution of such Awards with new Awards of the successor
entity or parent thereof (the "ASSUMPTION"), this Option shall terminate. In the
event of such termination of this Option, the Grantee shall be permitted to
exercise this Option to the extent that it is then exercisable, or becomes
exercisable in connection with the Change of Control, for a period of at least
ten (10) days prior to the anticipated effective date of such Change of Control;
PROVIDED, HOWEVER, that: (i) the exercise of the portion of this Option that
becomes vested and exercisable pursuant to the acceleration provisions set forth
herein, if any, shall be subject to and conditioned upon the effectiveness of
the Change of Control; and (ii) the Grantee may, but will not be required to,
condition the exercise of any portion of this Option not described in (i) above
upon the effectiveness of the Change of Control.

     7. WITHHOLDING TAXES.
        -----------------

         (a) PAYMENT BY GRANTEE. The Grantee shall, no later than the date as of
which the exercise of this Option (or, if applicable, the issuance, in whole or
in part of any Issued Shares, the operation of any law or regulation providing
for the imputation of interest related to this Option, or the lapsing of any
restriction with respect to any Issued Shares) gives rise to taxable income and
subjects the Company to a tax withholding obligation, authorize the Company to
withhold from payroll and any other amounts payable to the Grantee or pay to the
Company or make arrangements satisfactory to the Committee for payment of any
federal, state, foreign and local taxes required by law to be withheld with
respect to such income.

         (b) PAYMENT IN STOCK. Subject to approval by the Committee, in its sole
and absolute discretion, the Grantee may elect to have the minimum tax
withholding obligation satisfied, in whole or in part, by (i) authorizing the
Company to withhold from shares of Stock to

                                      -5-

<Page>

be issued a number of shares of Stock with an aggregate Fair Market Value (as of
the date the withholding is effected) that would satisfy the withholding amount
due or (ii) transferring to the Company shares of Stock owned by the Grantee
with an aggregate Fair Market Value (as of the date the withholding is effected)
that would satisfy the withholding amount due. The Fair Market Value of any
shares of Stock withheld or tendered to satisfy any such tax withholding
obligation shall not exceed the amount determined by the applicable minimum
statutory withholding rates.

     8. RESTRICTIONS ON TRANSFER OF ISSUED SHARES.
        -----------------------------------------

         If the Grantee (or a Permitted Transferee) shall receive a bona fide
offer from a third party for such third party to purchase any Issued Shares,
which offer the Grantee (or Permitted Transferee) intends to accept, the Grantee
(or Permitted Transferee), before consummating the sale to such third party,
shall comply with the right of first refusal and participation in sales
provisions in SECTIONS 2 and 3 of the Stockholders Agreement, dated as of
November 22, 2000, by and among the Company and certain of its stockholders, as
such agreement may be amended and/or restated from time to time. The
restrictions on transfer set forth above shall remain in effect until the
closing of a Change of Control or an Initial Public Offering (or such other
event as a result of or following which the common stock shall be publicly
held).

     9. COMPLIANCE WITH LEGAL REQUIREMENTS.
        ----------------------------------

         The grant of this Option and the issuance of shares of Stock upon
exercise of this Option shall be subject to compliance with all applicable
requirements of federal, state and foreign law with respect to such securities.
This Option may not be exercised if the issuance of shares of Stock upon
exercise would constitute a violation of any applicable federal, state or
foreign securities laws or other law or regulations or the requirements of any
stock exchange or market system upon which the Stock may then be listed. In
addition, this Option may not be exercised unless: (a) a registration statement
under the Act shall at the time of exercise of this Option be in effect with
respect to the shares issuable upon exercise, or (b) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of this Option may be
issued in accordance with the terms of an applicable exemption from the
registration requirements of the Act. The inability of the Company to obtain
from any regulatory body having jurisdiction and the authority, if any, deemed
by the Company's legal counsel to be necessary to the lawful issuance and sale
of any shares hereunder shall relieve the Company of any liability in respect of
the failure to issue or sell such shares as to which such requisite authority
shall not have been obtained. As a condition to the exercise of this Option, the
Company may require the Grantee to satisfy any qualifications that may be
necessary or appropriate, to evidence compliance with any applicable law or
regulation and to make any representation or warranty with respect thereto as
may be requested by the Company.

     10. LOCK-UP PROVISION.
         -----------------

         The Grantee and each Permitted Transferee agrees that in the event the
Company proposes to offer for sale to the public any shares of common stock of
the Company pursuant to a public offering under the Act, if requested in writing
by the Company and any underwriter engaged by the Company, not to directly or
indirectly, offer, sell, pledge, contract to sell

                                      -6-

(including any short sale), grant any option to purchase or otherwise dispose of
any securities of the Company held by them (except for any securities sold
pursuant to such registration statement) or enter into any Hedging Transaction
(as defined below) relating to any securities of the Company (including, without
limitation, pursuant to Rule 144 under the Act (or any successor or similar
exemptive rule hereinafter in effect)) held by them for such period following
the effective date of the registration statement of the Company filed under the
Act with respect to such offering, as the Company or such underwriter shall
specify reasonably and in good faith, not to exceed one hundred eighty (180)
days in the case of an initial public offering and ninety (90) days in the case
of any follow-on public offering. For purposes of this SECTION 10, "HEDGING
TRANSACTION" means any short sale (whether or not against the box) or any
purchase, sale or grant of any right (including without limitation, any put or
call option) with respect to any security (other than a broad-based market
basket or index) that includes, relates to or derives any significant part of
its value from the Company's common stock.

                          STOCK OPTION EXERCISE NOTICE

Optium Corporation
2721 Discovery Drive, Suite 500
Orlando, Florida, 32826
Attention: Chief Financial Officer/ Chief Executive Officer     Date:
                                                                     -----------

         Pursuant to the terms of the Notice of Grant of Stock Option dated
______________ _____, _____ and the Stock Option Agreement granted pursuant to
the Optium Corporation Stock Incentive Plan, as amended and entered into by
Optium Corporation and ______________________ on such date, I hereby [CIRCLE
ONE] partially/fully exercise such Option by including herein payment in the
amount of $__________ representing the purchase price for __________ shares of
Stock, all of which have vested in accordance with the Notice of Grant of Stock
Option. I hereby authorize payroll withholding or otherwise will make adequate
provision for federal, state, foreign and local tax withholding obligations of
the Company, if any, that arise in connection with the Option.

         I acknowledge that the shares are being acquired in accordance with and
subject to the terms, provisions and conditions of the Plan, the Notice of Grant
of Stock Option, and the Option Agreement, copies of which I have received and
carefully read and understand, including the Company's right of first refusal
and right of repurchase set forth therein, to all of which I hereby expressly
assent.

         I hereby represent that I am purchasing the shares of Stock for my own
account and not with a view to any sale or distribution thereof. I understand
that Rule 144, promulgated under the Securities Act of 1933, as amended, which
permits limited public resale of securities acquired in a nonpublic offering, is
not currently available with respect to such shares and, in any event, is
available only if certain conditions are satisfied. I acknowledge that any sale
of such shares that might be made in reliance on Rule 144 may only be made in
limited amounts in accordance with the terms and conditions of such rule and
that a copy of Rule 144 will be delivered to me upon my request. Finally, I
agree that, IF THE OPTION IS DESIGNATED AS AN "INCENTIVE STOCK OPTION" IN THE
NOTICE OF GRANT OF STOCK OPTION, that I will promptly notify the Chief Financial
Officer of the Company if I transfer any of the shares acquired pursuant to the
option within one (1) year from the date of exercise of all or part of the
Option or within two (2) years of the date of grant of the Option.

                                            Sincerely yours,

                                           -------------------------------------
