                 CHANGE IN CONTROL EXECUTIVE SEVERANCE AGREEMENT

         This Change in Control Executive Severance Agreement (this "Agreement")
is entered into this 9th day of July, 2003, by and between Serologicals
Corporation, a Georgia corporation having its principal place of business at
5655 Spalding Drive, Norcross, GA 30092 (the "Company"), and Vice Presidents
("Executive").

         The purpose of this Agreement is to afford Executive additional
security concerning his or her employment with the Company by providing for
certain termination payments to Executive if within 18 months following a Change
in Control, (i) the Company terminates Executive's employment without Cause or
(ii) Executive terminates his or her employment for Good Reason.

         Based upon the foregoing, and in consideration of Executive's continued
employment with the Company, the Company agrees as follows:

         1.       Term. This Agreement shall be effective as of the date first
written above and shall continue in effect until the earliest of (a) written
notice by the Company of cancellation of this Agreement, provided that no such
notice shall be effective within 12 months prior to, or within 18 months after,
a Change in Control, (b) termination of Executive's employment prior to a Change
in Control by Executive or the Company, or (c) termination of Executive's
employment within 18 months after a Change in Control by the Company for Cause,
by Executive without Good Reason, or as a result of Executive's death or
Disability.

         2.       Termination after Change in Control by Company without Cause
or by Executive for Good Reason. If at any time within 18 months after a Change
in Control, either (i) the Company terminates Executive's employment without
Cause, or (ii) Executive terminates his or her employment for Good Reason, then,
subject to paragraph 4, the Company shall provide the following to Executive:

                  (a)      Executive's base salary earned through the date of
         employment termination, but not previously paid;

                  (b)      reimbursement of reasonable and appropriate
         unreimbursed business expenses incurred by Executive through the date
         of termination; provided Executive submits supporting documentation
         thereof in accordance with the policies and procedures of the Company;

                  (c)      a pro rata portion of Executive's annual target bonus
         determined by multiplying (i) a fraction, the numerator of which is the
         number of days Executive was employed in the fiscal year in which
         Executive terminates employment and the denominator of which is 365, by
         (ii) Executive's annual target bonus for the fiscal year in which
         Executive's employment is terminated;

                  (d)      Two (2) times Executive's highest annual rate of base
         salary during the 18-month period prior to the date Executive's
         employment is terminated;

                  (e)      Two (2) times the greater of (i) Executive's annual
         target bonus for the fiscal year in which Executive's employment is
         terminated and (ii) Executive's annual bonus earned for the fiscal year
         immediately preceding the fiscal year in which Executive's employment
         is terminated;

                                       2

<PAGE>

                  (f)      Two (2) times the average of the Company's matching
         and profit sharing contributions, if any, allocated to Executive's
         account under the Company's 401(k) plan for the 3 years (or the period
         Executive was employed with the Company, if less) prior to the Change
         in Control;

                  (g)      Company-paid medical, disability and life insurance
         benefit coverage comparable to such coverage provided by the Company
         immediately prior to the Change in Control for a period of 2 years
         following the date of employment termination, to the extent comparable
         benefits are not provided by a subsequent employer of Executive during
         such period; provided that the Company, in its discretion, may elect,
         with respect to any or all of such insurance coverages at any time, to
         pay Executive cash in an amount that the Company in good faith
         determines to be equivalent to the cost to Executive to purchase such
         coverage for the entire period or any portion thereof;

                  (h)      The Company, at its expense, shall provide for
         outplacement services to Executive for the 6-month period following the
         date of employment termination by a mutually agreed upon outplacement
         services firm; and

                  (i)      Executive shall have the right to receive any
         benefits payable under the Company's employee benefit plans, programs
         and policies (other than any other severance pay plan, program or
         policy) which Executive otherwise has a nonforfeitable right to receive
         under the terms of such plans, programs and policies.

         3.       Other Termination. If Executive's employment is terminated (i)
for any reason prior to a Change in Control or (ii) within 18 months after a
Change in Control (A) by the Company for Cause, (B) by Executive without Good
Reason, or (C) as a result of Executive's

                                       3

<PAGE>

death or Disability, Executive shall be entitled to no payments or benefits
under this Agreement, other than as provided under paragraph 7.

         4.       Certain Additional Payments by Company.

                  (a)      If the Company or the Company's accountants determine
         that the payments or benefits called for under this Agreement or any
         other payments or benefits made available to Executive would constitute
         parachute payments (within the meaning of Section 280G(b) of the
         Internal Revenue Code of 1986, as amended (the "Code")) that would
         result in Executive being subject to an excise tax under Section 4999
         of the Code ("Payments"), and

                  (b)      If the Payments equal or exceed 115% of the Safe
         Harbor Amount (as defined in this paragraph 4), then the Company shall
         make a Gross-Up Payment (as defined in this paragraph 4) to or on
         behalf of Executive as and when such determination(s) and
         assessment(s), as appropriate, are made; provided Executive takes such
         action (other than waiving his or her right to any Payments) as the
         Company reasonably requests under the circumstances to mitigate or
         challenge such tax.

         If the Company or the Company's accountants determine that the Payments
exceed 100% but are less than 115% of the Safe Harbor Amount, then some or all
of the Payments (as determined by the Company in its absolute discretion) shall
be reduced to the extent the Company deems necessary so that such Payments are
no greater than the Safe Harbor Amount.

         The "Safe Harbor Amount" for purposes of this Agreement shall mean 2.99
times Executive's base amount (within the meaning of Section 280G(b) of the
Code). A "Gross-Up Payment" for purposes of this Agreement shall mean a payment
to or on behalf of Executive that

                                       4

<PAGE>

shall be sufficient to pay (i) any excise tax on the Payments under Section 4999
of the Code, (ii) any federal, state and local income tax and social security or
other employment tax, and any excise tax under Section 4999 of the Code, on the
amount described in clause (i) and the amounts described in this clause (ii),
and (iii) any interest or penalties assessed by the Internal Revenue Service on
Executive if such interest or penalties are attributable to the Company's
failure to comply with its obligations under this paragraph 4 or applicable law.
Any determination under this paragraph 4 by the Company or the Company's
accountants shall be made in accordance with Section 280G of the Code and any
applicable related regulations (whether proposed, temporary or final) and any
related Internal Revenue Service rulings and any related case law. For purposes
of determining the amount of the Gross-Up Payment, Executive shall be deemed to
pay federal income taxes at the highest marginal rate of federal income taxation
in the calendar year in which the Gross-Up Payment is to be made and state and
local income taxes at the highest marginal rates of taxation in the state and
locality of residence upon the date of termination, net of the maximum reduction
in federal income taxes that could be obtained from deduction of such state and
local taxes.

         If the Company reasonably requests that Executive take action to
mitigate or challenge, or to mitigate and challenge, any such tax or assessment
and Executive complies with such request, the Company shall provide Executive
with such information and such expert advice and assistance from the Company's
accountants, lawyers and other advisors as he or she may reasonably request and
shall pay for all expenses incurred in effecting such compliance and any related
fines, penalties, interest and other assessments.

                                       5

<PAGE>

         5.       Time of Payment. The Company shall pay any cash amounts due to
Executive under paragraph 2 in a lump sum payment within 30 days following
termination of Executive's employment.

         6.       No Other Severance Payments. If Executive receives payment
under paragraph 2, such payment shall be in lieu of any payment under any other
severance pay plan, program or policy of the Company, and Executive shall not be
entitled to any severance payments that might otherwise be payable to Executive,
whether by employment contract or otherwise. To the extent severance payment is
made under any other such severance pay plan, or otherwise, payment provided for
under paragraph 2 shall be offset by the amount of such payment.

         7.       Stock Options and Other Stock-Based Awards. All stock options,
stock appreciation rights, restricted stock, deferred stock units and other
stock-based awards of Executive ("awards") outstanding and not yet vested or
exercisable or which are subject to a substantial risk of forfeiture as of the
date of a Change in Control shall immediately vest and become immediately
exercisable and no longer subject to a substantial risk of forfeiture upon the
Change in Control, unless the agreement documenting the award provides otherwise
or such awards are assumed or replaced by the continuing or acquiring company.
If awards are assumed or replaced and the employment of Executive with the
continuing or acquiring company terminates for any reason other than Cause
within 18 months of the date of the Change in Control, then the assumed or
replaced awards outstanding and not yet exercisable or which are subject to a
substantial risk of forfeiture on the day prior to such termination shall
immediately vest and become immediately exercisable and no longer subject to a
substantial risk of forfeiture upon such termination.

         8.       Certain Definitions. For purposes of this Agreement, the
following terms have the meanings indicated:

                  (a)      The term "Board" as used in this Agreement means the
         board of directors of the Company.

                  (b)      The term "Cause" as used in this Agreement has the
         same meaning given such term in the employment agreement between
         Executive and the Company as of any date of determination, or if there
         is no such employment agreement or the employment agreement does not
         define "Cause," the term "Cause" means (i) an act of dishonesty causing
         harm to the Company or any Subsidiary; (ii) the knowing disclosure of
         confidential information relating to the Company's or any Subsidiary's
         business; (iii) habitual drunkenness or narcotic drug addiction; (iv)
         conviction of, or a plea of nolo contender with respect to, a felony;
         (v) the willful refusal to perform, or the gross neglect of, the duties
         assigned to Executive; (vi) Executive's willful breach of any law that,
         directly or indirectly, affects the Company or any Subsidiary; (vii)
         Executive's material breach of his or her duties following a Change in
         Control; provided that such duties do not differ in any material
         respect from Executive's duties during the 90-day period immediately
         prior to such Change in Control (other than as a result of incapacity
         due to physical or mental illness), which is demonstrably willful and
         deliberate on Executive's part, which is committed in bad faith or
         without reasonable belief that such breach is in the best interests of
         the Company or a Subsidiary, and which is not remedied in a reasonable
         period after receipt of written notice from the Company or any
         Subsidiary specifying such breach.

                  a person who acquires such securities directly from the
                  Company in a privately-negotiated transaction, of any
                  securities of the Company such that, as a result of such
                  acquisition, such person, entity or group either (x)
                  beneficially owns (within the meaning of Rule 13d-3 under the

                           (ii)     a change in the composition of the Board
                  such that a majority of the members of the Board are not
                  Continuing Directors;

                           (iii)    the stockholders of the Company approve a
                  merger or consolidation of the Company with any other business
                  entity, other than a merger or consolidation which would
                  result in the voting securities of the Company outstanding
                  immediately prior thereto continuing to represent (either by
                  remaining outstanding or by being converted into voting
                  securities of the surviving entity) more than 50% of the total
                  voting power represented by the

<PAGE>

                  voting securities of the Company or such surviving entity
                  outstanding immediately after such merger or consolidation; or

                           (iv)     the stockholders of the Company approve a
                  plan of complete liquidation of the Company or an agreement

                  transactions) all or substantially all of the Company's
                  assets.

         Notwithstanding the foregoing, the preceding events shall not be deemed
         to be a Change in Control if, prior to any transaction or transactions
         causing such a change, a majority of the Continuing Directors shall
         have voted not to treat such transaction or transactions as resulting
         in a Change in Control.

         majority of the Continuing Directors who were members of such Board at
         the time of such nomination or election.

                  (e)      The term "Disability" as used in this Agreement means
         termination because of Executive's failure to properly and fully
         perform the duties and responsibilities of his or her employment with
         the Company, due to mental or physical illness, for a period of 120
         consecutive days, or 180 days, even though not consecutive, within any
         360-day period, all as determined in good faith by the Board and
         supported by medical evidence.

<PAGE>

                  (f)      The term "Good Reason" as used in this Agreement
         means (i) a material reduction in Executive's job functions, duties or
         responsibilities, or a change in Executive's reporting relationships
         that has a material and adverse effect on the status of Executive's job
         functions, duties or responsibilities; (ii) any material reduction in
         Executive's base salary, target bonus or maximum bonus opportunity;
         (iii) absent Executive's consent, a required relocation of Executive of

         date of the Change in Control or a significant increase in required
         travel by Executive; (iv) the failure of any business entity with which
         the Company merges or consolidates, or to which the Company sells all
         or substantially all of its assets, to assume this Agreement; or (v)
         any material breach of any of the terms of this Agreement; provided,
         however, Good Reason shall not exist unless (A) Executive gives the
         Company a detailed, written statement of the circumstances that form
         the basis for Executive's belief that Good Reason exists and gives the
         Company a 15-day period after the delivery of such statement to cure
         the circumstances and (B) Executive actually resigns his or her
         employment with the Company after the end of such 15-day period (but no
         later than 60 days after the end of such 15-day period) if Executive
         reasonably and in good faith determines that Good Reason continues to
         exist after the end of such 15-day period.

                  (g)      The term "Subsidiary" as used in this Agreement means
         any corporation, partnership, joint venture or other business entity of
         which 50% or more of the outstanding voting power is beneficially
         owned, directly or indirectly, by the Company.

         9.       Amendment. This Agreement may be amended at any time by the
Board to the extent the Board deems necessary or appropriate upon written notice
by the Company of such

                                       10

<PAGE>

amendment; provided, however, absent Executive's written consent, no amendment
shall be effective within 12 months prior to, or within 18 months after, a
Change in Control to the extent the amendment adversely affects any rights of
Executive.

         10.      Attorneys' Fees. If any action at law or in equity is
necessary for Executive to enforce or interpret the terms of this Agreement, the
Company shall pay Executive's reasonable attorneys' fees and other expenses
incurred with respect to such action.

         11.      Partial Invalidity. If any provision of this Agreement is held
by a court of competent jurisdiction be invalid, void or unenforceable, the
remaining provisions shall nevertheless continue in full force without being
impaired or invalidated in any way.

         12.      Agreement Supersedes Any Inconsistent Prior Agreements or
Understandings. The terms of this Agreement supersede any prior promises,
policies, representations, understandings, arrangements or agreements between
the parties with respect to payments and benefits that become due as a result of
a change in control of the Company (including a Change in Control as defined in
this Agreement), including, but not limited to, any prior change in control
severance agreement that may have been entered into between the parties as of
March 27, 1998.

         13.      Not an Employment Contract. Nothing in this Agreement extends
or expands Executive's present rights concerning employment with the Company in
the absence of a Change in Control or is intended to create a contract,
guarantee or promise of continued employment by the Company. The Company shall
have no obligation hereunder if Executive's employment is terminated for any
reason prior to a Change in Control.

                                       11

<PAGE>

         14.      Employment with Subsidiary. A transfer between the Company and
a Subsidiary or between Subsidiaries shall not be treated as a termination of
employment with the Company under this Agreement.

         15.      Notices. All notices required or permitted to be given by
either party hereunder, including notice of change of address, shall be in
writing and delivered by hand, or mailed, postage prepaid, certified or
registered mail, return receipt requested, to the other party at the address set
forth below or to such other address as either party may from time to time
designate by 10 days advance written notice pursuant to this paragraph 15:

construed under the laws of the State of Georgia (without reference to the
choice of law principles thereof). Executive consents to jurisdiction and venue
in the state and federal courts of the State of Georgia for any action arising
from a dispute under this Agreement, and for any such action brought in such a

personal jurisdiction or improper venue, or that the action has been brought in
an inconvenient forum.

only and are not intended to affect the meaning of any provision hereof.

benefit of, and be binding upon, the Company, its successors and assigns and any
business entity with which the Company merges or consolidates or to which the
Company sells all or substantially all of its assets, and upon Executive and his
or her executors, administrators, heirs and legal representatives.
